This study was conducted to survey the background, knowledge, and interest in clinical research among junior and mid-career otolaryngologists.
　Methods : A questionnaire survey was distributed to 34 otolaryngologists with ≤15 years' clinical experience working at Okayama University and its affiliated facilities. The respondents were divided into junior (non-specialists) and mid-career otolaryngologists (specialists) based on whether they were board-certified otolaryngologists. The survey assessed their background, understanding, and interest in clinical research.
　Results : Twenty-nine otolaryngologists (83%) responded (10 junior and 19 mid-career otolaryngologists). There was significant individual variation in their interest and knowledge of clinical research. However, approximately half of the respondents indicated that they were not interested in and/or had never engaged in clinical research.
　Conclusion : The data collected by this survey contribute to our understanding of the current state of clinical research engagement among junior and mid-career otolaryngologists, and they can serve as a basis for exploring future strategies to increase this engagement. en-copyright= kn-copyright= en-aut-name=UraguchiKensuke en-aut-sei=Uraguchi en-aut-mei=Kensuke kn-aut-name=浦口健介 kn-aut-sei=浦口 kn-aut-mei=健介 aut-affil-num=1 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name=頼藤貴志 kn-aut-sei=頼藤 kn-aut-mei=貴志 aut-affil-num=2 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name=高尾総司 kn-aut-sei=高尾 kn-aut-mei=総司 aut-affil-num=3 ORCID= en-aut-name=SugayaAkiko en-aut-sei=Sugaya en-aut-mei=Akiko kn-aut-name=菅谷明子 kn-aut-sei=菅谷 kn-aut-mei=明子 aut-affil-num=4 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name=安藤瑞生 kn-aut-sei=安藤 kn-aut-mei=瑞生 aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil=岡山大学大学院医歯薬学総合研究科　疫学・衛生学 affil-num=2 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科　疫学・衛生学 affil-num=3 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科　疫学・衛生学 affil-num=4 en-affil=Department of Otolaryngology-Head and Neck Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学学術研究院医歯薬学域　耳鼻咽喉・頭頸部外科学 affil-num=5 en-affil=Department of Otolaryngology-Head and Neck Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学学術研究院医歯薬学域　耳鼻咽喉・頭頸部外科学 en-keyword=臨床研究 (clinical research) kn-keyword=臨床研究 (clinical research) en-keyword=統計解析 (statistical analysis) kn-keyword=統計解析 (statistical analysis) en-keyword=ビッグデータ (bigdata) kn-keyword=ビッグデータ (bigdata) en-keyword=質問紙調査 (questionnaire survey) kn-keyword=質問紙調査 (questionnaire survey) END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=1 article-no= start-page=1 end-page=15 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Improved sedimentary layer model including the accretionary prism in the fore-arc region of the Ryukyu arc, Japan kn-title=南西諸島の前弧域における付加体を含む堆積層のモデル化 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　We combine the recent seismic reflection profiles to construct a new seismic velocity model of the sedimentary layer incorporating the accretionary prism along the Ryukyu trench. In constructing the new model, we refer to the zoning (ZONE1 to ZONE4) identified by Okamura et al. (2017, Tectonophys.). The construction process consists of the following steps: First, we digitize either unconformities or VP=4 to 5 km/s lines as the seismic basement, whichever is more clearly identifiable. Second, the digitized thickness data of the sedimentary layer from the reflection profiles are geometrically modeled and interpolated to make the three-dimensional structure model. Finally, we supplement the external region of the constructed 3-D sedimentary model using the J-SHIS model provided by the NIED to complete the velocity structure model in the entire Ryukyu arc. The main features of our model are as follows: In ZONE1, off Ishigaki-jima island, the thick sedimentary layer extends about 50 km wide from the Ryukyu trench. In ZONE2, off Miyako-jima island, the thinner layer compared to the other zones is found near the trench, with a thin sedimentary terrace covering the area behind it. In ZONE3, off Okinawa-jima island, the sedimentary layer deepens as it approaches the trench. In ZONE4, off Tokara islands, the deepest layer among all zones is identified. We then conduct 3-D finite-difference simulations of seismic wave propagation using the new and the previous models to confirm the improvement of the new model. In the simulations, the effects of the accretionary prism along the Ryukyu trench on the seismic wave propagation are clearly identified. en-copyright= kn-copyright= en-aut-name=KOMATSUMasanao en-aut-sei=KOMATSU en-aut-mei=Masanao kn-aut-name=小松正直 kn-aut-sei=小松 kn-aut-mei=正直 aut-affil-num=1 ORCID= en-aut-name=URAKAMISohei en-aut-sei=URAKAMI en-aut-mei=Sohei kn-aut-name=浦上想平 kn-aut-sei=浦上 kn-aut-mei=想平 aut-affil-num=2 ORCID= en-aut-name=OKAMOTOTaro en-aut-sei=OKAMOTO en-aut-mei=Taro kn-aut-name=岡元太郎 kn-aut-sei=岡元 kn-aut-mei=太郎 aut-affil-num=3 ORCID= en-aut-name=TAKENAKAHiroshi en-aut-sei=TAKENAKA en-aut-mei=Hiroshi kn-aut-name=竹中博士 kn-aut-sei=竹中 kn-aut-mei=博士 aut-affil-num=4 ORCID= affil-num=1 en-affil=Okayama Gakuin University kn-affil=岡山学院大学 affil-num=2 en-affil=Formerly Department of Earth Sciences, Okayama University kn-affil=元・岡山大学大学院自然科学研究科 affil-num=3 en-affil=Department of Earth and Planetary Sciences, School of Science, Institute of Science Tokyo kn-affil=東京科学大学理学院地球惑星科学系 affil-num=4 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学学術研究院環境生命自然科学学域 en-keyword=Sedimentary layer model kn-keyword=Sedimentary layer model en-keyword=Accretionary prism kn-keyword=Accretionary prism en-keyword=Ryukyu arc kn-keyword=Ryukyu arc END start-ver=1.4 cd-journal=joma no-vol=41 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250321 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=津島岡大遺跡 23 ―第37次調査―（異分野基礎科学研究所新営に伴う発掘調査） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=木村理 kn-aut-sei=木村 kn-aut-mei=理 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=山口雄治 kn-aut-sei=山口 kn-aut-mei=雄治 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=宇田津徹朗 kn-aut-sei=宇田津 kn-aut-mei=徹朗 aut-affil-num=3 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=田﨑博之 kn-aut-sei=田﨑 kn-aut-mei=博之 aut-affil-num=4 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=那須浩郎 kn-aut-sei=那須 kn-aut-mei=浩郎 aut-affil-num=5 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=白石純 kn-aut-sei=白石 kn-aut-mei=純 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学文明動態学研究所 affil-num=2 en-affil= kn-affil=岡山大学文明動態学研究所 affil-num=3 en-affil= kn-affil=宮崎大学 affil-num=4 en-affil= kn-affil=愛媛大学名誉教授 affil-num=5 en-affil= kn-affil=岡山理科大学 affil-num=6 en-affil= kn-affil=元岡山理科大学 END start-ver=1.4 cd-journal=joma no-vol=2023 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Bulletin of Cultural Heritage Management Division Research Institute for the Dynamics of Civilizations Okayama University 2023 kn-title=岡山大学文明動態学研究所文化遺産マネジメント部門紀要2023 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=柴田亮 kn-aut-sei=柴田 kn-aut-mei=亮 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=パレオ・ラボAMS年代測定グループ kn-aut-sei=パレオ・ラボAMS年代測定グループ kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=木村理 kn-aut-sei=木村 kn-aut-mei=理 aut-affil-num=3 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=野﨑貴博 kn-aut-sei=野﨑 kn-aut-mei=貴博 aut-affil-num=4 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=山口雄治 kn-aut-sei=山口 kn-aut-mei=雄治 aut-affil-num=5 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岩﨑志保 kn-aut-sei=岩﨑 kn-aut-mei=志保 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学文明動態学研究所文化遺産マネジメント部門 affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil=岡山大学文明動態学研究所文化遺産マネジメント部門 affil-num=4 en-affil= kn-affil=岡山大学文明動態学研究所文化遺産マネジメント部門 affil-num=5 en-affil= kn-affil=岡山大学文明動態学研究所文化遺産マネジメント部門 affil-num=6 en-affil= kn-affil=岡山大学文明動態学研究所文化遺産マネジメント部門 END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=12633 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association of emergency intensive care unit occupancy due to brain-dead organ donors with ambulance diversion en-subtitle= kn-subtitle= en-abstract= kn-abstract=Our study aims to explore how intensive care unit (ICU) occupancy by brain-dead organ donors affects emergency ambulance diversions. In this retrospective, single-center study at an emergency ICU (EICU), brain-dead organ donors were managed until organ procurement. We classified each day between August 1, 2021, and July 31, 2023, as either an exposure day (any day with a brain-dead organ donor in the EICU from admission to organ procurement) or a control day (all other days). The study compared these days and used multiple logistic regression analysis to assess the impact of EICU occupancy by brain-dead organ donors on ambulance diversions. Over two years, 6,058 emergency patients were transported by ambulance, with 1327 admitted to the EICU, including 13 brain-dead organ donors. Brain-dead donors had longer EICU stays (17 vs. 2 days, P < 0.001). With 168 exposure and 562 control days, EICU occupancy was higher on exposure days (75% vs. 67%, P = 0.003), leading to more ambulance diversions. Logistic regression showed exposure days significantly increased ambulance diversions, with an odds ratio of 1.79 (95% CIs 1.10-2.88). This study shows that managing brain-dead organ donors in the EICU leads to longer stays and higher occupancy, resulting in more frequent ambulance diversions. These findings highlight the critical need for policies that optimize ICU resource allocation while maintaining the infrastructure necessary to support organ donation programs and ensuring continued care for brain-dead donors, who play an essential role in addressing the organ shortage crisis. en-copyright= kn-copyright= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name=

kn-subtitle= en-abstract= kn-abstract=In contemporary end-of-life care, it is difficult for patients to make decisions without the influence of society, family, and other factors. In many cases, patients have the capacity to make the decisions; nevertheless, they have difficulty expressing their own will because of the influence of their relationships and environment. Patient concerns about the burden of care and also the social and economic impacts on family members often hinder their use of imagination and decision-making. Therefore, this study has examined how patients with decision-making capacities could achieve autonomy under the influence of their relationships with their surroundings. The method of decision-making support provided by nurses to patients was examined using relational autonomy theory. Relational autonomy theory attempts to reconceptualize autonomy through feminists who criticize individualist theories of autonomy. en-copyright= kn-copyright= en-aut-name=SONOYAMASumiyo en-aut-sei=SONOYAMA en-aut-mei=Sumiyo kn-aut-name=園山純代 kn-aut-sei=園山 kn-aut-mei=純代 aut-affil-num=1 ORCID= affil-num=1 en-affil=The University of Shimane kn-affil=島根県立大学 en-keyword=relational autonomy kn-keyword=relational autonomy en-keyword=decision-making kn-keyword=decision-making en-keyword=end of life care kn-keyword=end of life care END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=1 end-page=9 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Corporate decision-making process for exploration time kn-title=知の探索時間についての企業の意思決定プロセス en-subtitle= kn-subtitle= en-abstract= kn-abstract=In order for companies to innovate through business co-creation, it is necessary to explore a wide range of external knowledge and technologies. However, there is no clear answer as to how much time should be spent for exploration. Under these circumstances, companies must take into account constraints such as the amount of management resources that can be invested, and make decisions about the time to spend for exploration. The purpose of this paper is to clarify the process of how companies that have introduced corporate accelerator program recognize the relationship between the program period and the results of business co-creation, and how they make decisions about the program period.

Kazuo Inamori's Philosophy, the Teachings of Nanshu Saigo, and the Iroha Poem by Prince Jisshin kn-title=稲盛和夫のフィロソフィーと西郷南洲翁遺訓及び日新公いろは歌の連関についての考察 en-subtitle= kn-subtitle= en-abstract=Kazuo Inamori is a rare business leader who founded DDI, the predecessor of Kyocera and KDDI, in one generation, and grew it into a trillion-yen company. He also rebuilt the bankrupt Japan Airlines (JAL) in three years and led it to relisting. He has not only led tens of thousands of people with his unique management method called amoeba management, but also with management principles. What are the roots of the way of life that a manager of a small and medium-sized business has derived from management? What is the Goju education that is the foundation of Satsuma, where he was born and raised? From the perspective of business management, it is interesting to know what it is like.
How is it related to Saigo Nanshu Ikun, the record of the words and deeds of Saigo Takamori, a local hero whom Kazuo Inamori met after founding Kyocera and used as the basis of his own management philosophy, and Shimazu Nisshin Iroha Uta, left by Shimazu Tadayoshi (Nissin), the father of Shimazu Takahisa, the 15th lord of the Shimazu clan who unified southern Kyushu, including Satsuma and Hyuga, in the 16th century? First of all, I am interested in the relationship between the ideas of the three men born in Satsuma. In this study, we used the grounded theory approach, a qualitative research method, to analyze the correlation between Kazuo Inamori's philosophy, the teachings of Nanshu Saigo, and the Nisshin Iroha Uta. As a result, the analysis revealed that the three concepts are related across 400 years of time. In particular, Kazuo Inamori's philosophy is not only positively influenced by the teachings of Nanshu Saigo, which are the words and deeds of Takamori Saigo, whom Kazuo Inamori admires, but also by the Nisshin Iroha Uta, which dates back 400 years, due to his education in Satsuma. It is believed that the ideals that the people of Satsuma have inherited for 400 years contain concepts that should be the foundation for people's lives, or that should be important core ideas and qualities in life, regardless of the era. kn-abstract=　一代で京セラやKDDIの前身となる第二電電（DDI）を創業し、合計数兆円企業に育て、倒産した日本航空（JAL）を3年で再建し、再上場に導いた稀代の経営者稲盛和夫は、アメーバ経営という独自の経営手法だけでなく、理念経営により数万人を導いてきた。中小企業の一経営者が経営の中から導き出した人生成功の処世術のルーツは何処にあるのか。生まれ育った薩摩の基礎となる郷中（ごじゅう）教育とは何か、などについて経営学の観点から関心が湧く。
　稲盛和夫が京セラ創業以降に出会い、自ら経営理念の基礎とした地元の偉人である西郷隆盛の言行録である西郷南洲翁遺訓及び16世紀に薩摩や日向など南九州を統一した島津家第15代領主島津貴久公の実父島津忠良（日新）が残した、島津日新公いろは歌とどのように連関があるのか。そもそも薩摩生まれの3名の思想にどのような連関があるのか、についても関心が湧く。この研究では、質的研究法であるグラウンデッド・セオリー・アプローチを援用して、稲盛和夫のフィロソフィーと西郷南洲翁遺訓及び日新公いろは歌の連関について分析した。結果的に3つの概念は400年の時代を超えて、連関していることが分析により明らかになった。特に稲盛和夫のフィロソフィーが稲盛和夫が敬愛する西郷隆盛の言行録である西郷南洲翁遺訓に正の影響を受けているだけでなく、薩摩での教育を背景に、400年前に遡る日新公いろは歌からも正の影響を受けていることが明らかになった。400年に渡り薩摩の人々が受け継いできた理念には、時代を超えても人が生きていく中で基礎とすべき、もしくは人生で重要なコアな思想・資質とすべき概念があると考えられる。 en-copyright= kn-copyright= en-aut-name=MACHIDAHisashi en-aut-sei=MACHIDA en-aut-mei=Hisashi kn-aut-name=町田尚史 kn-aut-sei=町田 kn-aut-mei=尚史 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学教育推進機構 en-keyword=稲盛和夫 (Kazuo Inamori) kn-keyword=稲盛和夫 (Kazuo Inamori) en-keyword=フィロソフィー (philosophy) kn-keyword=フィロソフィー (philosophy) en-keyword=西郷隆盛 (Takamori Saigo) kn-keyword=西郷隆盛 (Takamori Saigo) en-keyword=西郷南洲翁遺訓 (the teachings of Nanshu Saigo) kn-keyword=西郷南洲翁遺訓 (the teachings of Nanshu Saigo) en-keyword=島津忠良（日新） (Tadayoshi Shimazu (Nissin)) kn-keyword=島津忠良（日新） (Tadayoshi Shimazu (Nissin)) en-keyword=日新公いろは歌 (Nisshin Iroha Uta) kn-keyword=日新公いろは歌 (Nisshin Iroha Uta) en-keyword=グラウンデッド・セオリー・アプローチ (grounded theory approach) kn-keyword=グラウンデッド・セオリー・アプローチ (grounded theory approach) END start-ver=1.4 cd-journal=joma no-vol=59 cd-vols= no-issue= article-no= start-page=15 end-page=24 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=（Translation）katrina Jaworski : The Gender of suicide, Part２ kn-title=カトリーナ・ジャボルスキ：自殺とジェンダーの社会学 ――文学部プロジェクト（ジェンダーの多層性に関する領域横断的研究3）の講演記録（後編）―― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SAITOKeisuke en-aut-sei=SAITO en-aut-mei=Keisuke kn-aut-name=齋藤圭介 kn-aut-sei=齋藤 kn-aut-mei=圭介 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院社会文化科学学域 END start-ver=1.4 cd-journal=joma no-vol=59 cd-vols= no-issue= article-no= start-page=1 end-page=14 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Study on the Accessibility of Admissions Information: Comparison of universities in Japan, East and South-East Asia and English-speaking countries kn-title=入学情報へのアクセス性に関する研究 ―日本、東・東南アジア、英語圏の大学との比較から― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=INAMORITakao en-aut-sei=INAMORI en-aut-mei=Takao kn-aut-name=稲森岳央 kn-aut-sei=稲森 kn-aut-mei=岳央 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学グローバル人材育成院 END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=3-4 article-no= start-page=312 end-page=278 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=CJEU Cases on the Montreal Convention 1999 kn-title=モントリオール条約に関する CJEU 判例の紹介 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MasudaF. en-aut-sei=Masuda en-aut-mei=F. kn-aut-name=増田史子 kn-aut-sei=増田 kn-aut-mei=史子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院社会文化科学学域 END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学教師教育開発センターの活動状況の概要 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=357 end-page=371 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Proposals for Supporting Children’s Adaptation in School Mergers and Closures kn-title=学校統廃合における児童の適応支援策の提言 en-subtitle= kn-subtitle= en-abstract=The purpose of this study is to examine the impact of school mergers and closures on children through a literature review and field survey and to propose strategies for supporting children's adaptation to the resulting environmental transitions. First, a literature review on school mergers and closures indicated that such experiences could influence children's later interpersonal relationships and increase stress responses. However, research on the impact of school mergers and closures on children remains limited, with insufficient understanding of their psychological effects on children. Next, interviews conducted as part of a field survey revealed that school mergers and closures could be significant sources of stress for children. Based on these findings, we recommends multi-level support measures targeting individuals, classes, grades, and entire schools, primarily through special activities, to help mitigate the impact of these transitions on children. kn-abstract=本研究の目的は，学校統廃合に係る文献検索および実態調査を通して，学校統廃合という環境移行が児童に与える影響について検討し，学校統廃合がもたらす環境移行に対する児童の適応支援策について提言することである。まず，学校統廃合に係る文献検索を行った結果，学校統廃合の経験が児童生徒のその後の人間関係形成やストレス反応の増加に影響を与えている可能性が示された。しかし，学校統廃合が児童に与える影響に関する研究は非常に少なく，統廃合の経験が児童に与える心理的影響については十分に解明されていないことがわかった。次に，実態調査として行ったインタビューにおいて，学校統廃合が児童にとって大きなストレス要因となる可能性があることがわかった。これらの現状を踏まえて，学校統廃合が児童に与える影響を和らげるため，特別活動を中心として，個人・学級・学年・学校レベルでの具体的な取組を提案した。 en-copyright= kn-copyright= en-aut-name=IKEDAYuka en-aut-sei=IKEDA en-aut-mei=Yuka kn-aut-name=池田祐加 kn-aut-sei=池田 kn-aut-mei=祐加 aut-affil-num=1 ORCID= en-aut-name=IZUMITsuguyuki en-aut-sei=IZUMI en-aut-mei=Tsuguyuki kn-aut-name=伊住継行 kn-aut-sei=伊住 kn-aut-mei=継行 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education (Professional Degree Corse), Okayama University kn-affil=岡山大学大学院教育学研究科大学院生 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=学校統廃合 (School Consolidation) kn-keyword=学校統廃合 (School Consolidation) en-keyword=児童 (Children) kn-keyword=児童 (Children) en-keyword=人間関係形成 (Relationship Building) kn-keyword=人間関係形成 (Relationship Building) en-keyword=ストレス (Stress) kn-keyword=ストレス (Stress) en-keyword=特別活動 (Special Activities) kn-keyword=特別活動 (Special Activities) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=341 end-page=355 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Research Trends on Educational Needs and Support of Children with Cancer kn-title=小児がん患児に対する教育的支援とその研究動向 en-subtitle= kn-subtitle= en-abstract=　In this study, we summarized research trends related to the educational needs and support of children with cancer from the perspectives of “learning,” “self-management,” “interpersonal,” “psychological,” and “collaboration,”. In terms of learning, the study showed that experiential learning and distance education are solutions to the problem of delayed learning due to prolonged absence from school and poor concentration during treatment. Next, in self-management, it is important to educate affected children so that they can fully understand the disease and treatment. In addition, in terms of interpersonal support, it is difficult for the affected patients to build relationships with friends, but providing opportunities for interaction is expected to contribute to the improvement of interpersonal relationships. In terms of psychological support, the anxiety associated with treatment is a major psychological burden for the affected children, and the understanding of their friends and the intervention of university student volunteers are effective in helping them achieve psychological stability. Finally, the lack of cooperation between medical institutions and schools was highlighted as a deficiency in the support system, which needs to be strengthened. In the future, these support measures should be empirically verified to establish a sustainable support system. kn-abstract=　本研究は、小児がん患児の教育的支援に関する研究の動向を明らかにし、今後の課題とその解決策を提起することを目的とした。「学習」、「自己管理」、「対人」、「心理」、「連携」の5つの視点から分析を行った。学習支援について、治療に伴う学習の遅れや集中力の低下に対し、個別の教育支援計画や体験的な学習、および遠隔教育の実施に期待されていた。自己管理支援では、患児が自身の病状や治療による副作用を理解し、自立的に管理できる能力を育成することが求められていた。対人支援について、患児の長期入院により、友人関係の構築が困難になり、入院中や復学後のコミュニケーションの支援が重要であることが確認された。心理支援においては、周囲への効果的ながん教育や大学生ボランティアによる支援が、患児の心理的安定を促すことが示された。最後に、学校と医療機関、保護者の連携不足が指摘されており、連携ツールの開発が求められている。 en-copyright= kn-copyright= en-aut-name=CHENYiwen en-aut-sei=CHEN en-aut-mei=Yiwen kn-aut-name=陳依文 kn-aut-sei=陳 kn-aut-mei=依文 aut-affil-num=1 ORCID= en-aut-name=YOSHITOSHIMunehisa en-aut-sei=YOSHITOSHI en-aut-mei=Munehisa kn-aut-name=吉利宗久 kn-aut-sei=吉利 kn-aut-mei=宗久 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education Doctoral Programs, Hyogo University of Teacher Education kn-affil=兵庫教育大学大学院連合学校教育学研究科博士課程 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=小児がん (child hood cancer) kn-keyword=小児がん (child hood cancer) en-keyword=慢性疾患 (chronic illness) kn-keyword=慢性疾患 (chronic illness) en-keyword=教育的ニーズ (educational needs) kn-keyword=教育的ニーズ (educational needs) en-keyword=研究動向 (research trends) kn-keyword=研究動向 (research trends) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=297 end-page=311 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Exploring Home Learning That Bridges Lessons to Foster Autonomous and Self-Directed Learning kn-title=主体的・自律的な学びを萌芽させる「授業と授業をつなぐ家庭学習」の探究 en-subtitle= kn-subtitle= en-abstract=　For students to develop the ability to learn independently, they need learning experiences that extend beyond the classroom, including at home. In other words, learning is not confined to the classroom but is reinforced through a wide range of activities. This study aimed to nurture “autonomous and self-directed learning” among students in the second grade at a public junior high school by integrating classroom and home learning. Teachers emphasized the importance of learning strategies and goal setting, and encouraged metacognition. As a result, students became more aware of the self-regulated learning cycle and began exploring learning strategies tailored to their needs. In addition, working at home on assignments connected to the class not only increased students’ active participation in class but also improved their motivation to learn independ ently outside of class. kn-abstract=　生徒が自ら学習を進めていく力を身に付けるには，授業内だけでなく，家庭など授業外の場での学習経験を積む必要がある。つまり，学習は授業内だけで完結するのではなく，広範な活動を通して成立する。本研究では，公立中学校の第2学年を対象に授業と家庭学習を連携させる実践を行い，生徒の「主体的・自律的な学び」を萌芽させることを目指した。教師が学習方略や目標設定の重要性を伝え，メタ認知を促すことで，生徒は自己調整学習のサイクルを意識し，自分なりの学習方略を探求するようになった。また，家庭学習で授業につながる課題に取り組むことで，授業への主体的な参加と，授業外で自律的に学ぶ意欲が促されることも示唆された。 en-copyright= kn-copyright= en-aut-name=TANAKAJunko en-aut-sei=TANAKA en-aut-mei=Junko kn-aut-name=田中純子 kn-aut-sei=田中 kn-aut-mei=純子 aut-affil-num=1 ORCID= en-aut-name=MISAWARyo en-aut-sei=MISAWA en-aut-mei=Ryo kn-aut-name=三沢良 kn-aut-sei=三沢 kn-aut-mei=良 aut-affil-num=2 ORCID= affil-num=1 en-affil=Okayama Municipal Hosen Junior High School kn-affil=岡山市立芳泉中学校 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=授業と家庭学習の連携 (coordination between classroom and home learning) kn-keyword=授業と家庭学習の連携 (coordination between classroom and home learning) en-keyword=自己調整学習 (self-regulated learning) kn-keyword=自己調整学習 (self-regulated learning) en-keyword=宿題 (homework) kn-keyword=宿題 (homework) en-keyword=授業改善 (lesson improvement) kn-keyword=授業改善 (lesson improvement) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=281 end-page=295 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Development Support a Child with Autism to Acquisition of Intersubjective Communication: Through the Environmental Setting of Play with Shared Positive Emotions kn-title=ASD 児における相互伝達行為の獲得を目指した遊びを中心としたコミュニケーション指導　ポジティブな情動の共有を生み出す遊びの環境設定を通して en-subtitle= kn-subtitle= en-abstract=In this study, a play-based instruction was used to promote the acquisition of intersubjective communication in a special needs school for students with intellectual disabilities. The participant was a first-grade boy with autism. As a result, the boy began to show intersubjective communication and to respond to the teacher's instruction. It was suggested that four aspects of the play environment may have promoted the acquisition of intersubjective communication: 1) attractive toys, 2) play with the teacher through attractive toys, 3) intervention according to the developmental process of the target children's play, and 4) empathic involvement to encourage the affective sharing. kn-abstract=　自閉スペクトラム症児は，相互伝達行為の獲得に遅れがあることが指摘されている。本研究では，自閉スペクトラム症の診断のある知的障害特別支援学校小学部１年生男児を対象に，相互伝達行為の獲得を目指して，遊びを中心とした指導を行った。その結果，対象児の遊びが「感覚運動的遊び」「機能的遊び」から「象徴的遊び」「社会的遊び」へと移行するに伴い，相互伝達行為が見られるようになった。また，教師による働き掛けへの応答も見られるようになり，ポジティブな情動の共有が生み出されやすい遊びの環境設定が，相互伝達行為の獲得において効果的であったことが示唆された。遊び環境については，1）魅力的な玩具，2）魅力的な玩具を介した教師との遊び，3）対象児の遊びの発達段階に応じた介入，4）情動の共有を促す共感的関わりの４点が相互伝達行為の獲得を促した可能性が考えられた。 en-copyright= kn-copyright= en-aut-name=KAKUHARAKeisuke en-aut-sei=KAKUHARA en-aut-mei=Keisuke kn-aut-name=角原佳介 kn-aut-sei=角原 kn-aut-mei=佳介 aut-affil-num=1 ORCID= en-aut-name=BANMarina en-aut-sei=BAN en-aut-mei=Marina kn-aut-name=伴真里奈 kn-aut-sei=伴 kn-aut-mei=真里奈 aut-affil-num=2 ORCID= en-aut-name=TANJITakayuki en-aut-sei=TANJI en-aut-mei=Takayuki kn-aut-name=丹治敬之 kn-aut-sei=丹治 kn-aut-mei=敬之 aut-affil-num=3 ORCID= affil-num=1 en-affil=Tobi Special School kn-affil=岡山県立東備支援学校 affil-num=2 en-affil=Special School Affiliated with the Faculty of Education at Okayama University kn-affil=岡山大学教育学部附属特別支援学校 affil-num=3 en-affil=Institute of Human Sciences, University of Tsukuba kn-affil=筑波大学人間系 en-keyword=自閉スペクトラム症 (a Child with Autism) kn-keyword=自閉スペクトラム症 (a Child with Autism) en-keyword=相互伝達行為 (Intersubjective Communication) kn-keyword=相互伝達行為 (Intersubjective Communication) en-keyword=情動の共有 (effective sharing) kn-keyword=情動の共有 (effective sharing) en-keyword=遊びの環境設定 (Setting of Play) kn-keyword=遊びの環境設定 (Setting of Play) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=267 end-page=279 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Examination of Practical Cases of Career Education to Promote Self-Understanding in Elementary School Students: Utilizing Character Strengths Intervention kn-title=児童の自己理解を促すキャリア教育の実践事例の検討　―強み介入を活用して― en-subtitle= kn-subtitle= en-abstract=This study explored the implementation of Character Strengths Intervention (CSI), rooted in positive psychology, to enhance self-awareness in career education for elementary school students. The intervention targeted 4th-grade students at a public elementary school, aiming to facilitate their recognition and utilization of character strengths in relation to future aspirations. Through structured lessons, students deepened their understanding of personal strengths and developed increased awareness of how to apply these attributes towards their future goals. Moreover, peer-focused activities designed to acknowledge individual strengths contributed to improved interpersonal relationships among students.

Participants reflected on these discussions, and the content was analyzed. (1) A screening sheet to identify children who “cause concern” helped clarify differences in observations, leading to a shared understanding of child perceptions. (2) Teachers recognized differences in their views of children and education, improving their attitudes toward compromise and increasing awareness of the need to smooth the transition. However, an overloaded elementary school curriculum was noted, limiting the flexible application of the start curriculum and hindering child-centered education. kn-abstract=本実践では，５歳児から小学１年生の「架け橋期」の滑らかな移行に焦点を当てたスタートカリキュラム共同編成プロジェクトを立ち上げ，幼稚園と小学校の教員が集まって５回の話合いを行った。本プロジェクトを評価するために，参加者に話合いの振返りを書いてもらい，その内容を検討した。成果として，①スクリーニングシートを使って，「気になる」子供を抽出し，見取りの違いを可視化することで，相互の子供観について共通理解を図ることができた。②幼稚園と小学校，双方の教員が互いの子供観・教育観の違いを理解し，歩み寄ろうとする姿勢や校種間の接続をより滑らかにしようとする意識の向上が確認された。一方，課題として，スタートカリキュラムの柔軟な運用や小学校教育における子供主体の教育の実現を妨げる教育課程の過積載状態の問題が指摘された。 en-copyright= kn-copyright= en-aut-name=OKURAHisashi en-aut-sei=OKURA en-aut-mei=Hisashi kn-aut-name=大倉尚志 kn-aut-sei=大倉 kn-aut-mei=尚志 aut-affil-num=1 ORCID= en-aut-name=MATSUINoriko en-aut-sei=MATSUI en-aut-mei=Noriko kn-aut-name=松井紀子 kn-aut-sei=松井 kn-aut-mei=紀子 aut-affil-num=2 ORCID= en-aut-name=IZUMITsuguyuki en-aut-sei=IZUMI en-aut-mei=Tsuguyuki kn-aut-name=伊住継行 kn-aut-sei=伊住 kn-aut-mei=継行 aut-affil-num=3 ORCID= affil-num=1 en-affil=Hayashima Kindergarten kn-affil=早島町立早島幼稚園 affil-num=2 en-affil=Hayashima Kindergarten kn-affil=早島町立早島幼稚園 affil-num=3 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=架け橋プログラム (Bridge Program) kn-keyword=架け橋プログラム (Bridge Program) en-keyword=スタートカリキュラム (Start Curriculum) kn-keyword=スタートカリキュラム (Start Curriculum) en-keyword=スクリーニングシート (Screening Sheet) kn-keyword=スクリーニングシート (Screening Sheet) en-keyword=カリキュラム・オーバーロード (Curriculum Overload) kn-keyword=カリキュラム・オーバーロード (Curriculum Overload) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=235 end-page=249 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Practical Research on Nurturing the Next Generation of Classical Japanese Instrument Music That Connects the Local and the Global Community (1): Analysis of External Evaluations of the “Okayama International Classical Japanese Instruments Student Festival” kn-title=地域社会とグローバルをつなぐ和楽器音楽次世代育成の実践研究（１）　「おかやま国際和楽器学生フェスティバル」外的評価の分析 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　本稿では，「和楽器音楽及び教育の拠点づくりの実践研究」の一環として開催した「おかやま国際和楽器学生フェスティバル」の取り組みについて，その概要を報告するとともに，外的評価として「おかやま国際和楽器学生フェスティバルコンサート」終演後に実施した一般来場者対象の質問紙調査及びフェスティバルを参観した岡山県内の学校関係者対象の質問紙調査を取り上げ，意義と課題について検討した。

Diachronic Surveys kn-title=中学校理科教科書がつくり上げてきたきのこ像　―通時的調査から得るきのこを巡る学習への示唆― en-subtitle= kn-subtitle= en-abstract=　In this paper, we examined the image of mushroom in postwar junior high school science textbooks from four perspectives: (1) which species of mushroom were covered, (2) whether they were classified as plants or not, (3) what makes up the body of a mushroom, and (4) how they functioned in an ecosystem. The 47 species were identified through a periodic survey. Although a total of 47 species have appeared in science textbooks, we pointed out that in recent years, the focus has shifted to the role of mushroom as decomposers, rather than to species awareness. We also pointed out that although mycorrhizal fungi have been discussed in textbooks, there was no reference to the perspective in a plant-fungal symbiosis, which raises the possibility of developing learning that aims to understand symbiosis/interactions within a nature ecosystem. kn-abstract=　本稿では，戦後中学校理科検定教科書におけるきのこの扱われ方，すなわち学習者が受け取ることになるきのこ像について，①どのようなきのこが扱われてきたのか，②植物に分類されているか否か，③きのこのからだは何で形成されているのか，④生態系における働きの四つの観点から，通時的な調査によって明らかにした。全47種がこれまでの理科教科書で登場してきたが，近年は種への意識というよりも，きのこが分解者としての役割を持つことにのみ焦点が当てられてきていることを指摘した。また，これまで教科書においては菌根性のきのこ自体について取り上げられつつも，その生態系における相利共生の観点への言及はないことから，相利共生の理解を目指す学習の開発が可能性として浮かび上がってくることも指摘した。 en-copyright= kn-copyright= en-aut-name=TAKAGIRisa en-aut-sei=TAKAGI en-aut-mei=Risa kn-aut-name=髙木里彩 kn-aut-sei=髙木 kn-aut-mei=里彩 aut-affil-num=1 ORCID= en-aut-name=IKEDAMasafumi en-aut-sei=IKEDA en-aut-mei=Masafumi kn-aut-name=池田匡史 kn-aut-sei=池田 kn-aut-mei=匡史 aut-affil-num=2 ORCID= en-aut-name=YAMAMOTOMasaya en-aut-sei=YAMAMOTO en-aut-mei=Masaya kn-aut-name=山本将也 kn-aut-sei=山本 kn-aut-mei=将也 aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Education (Professional Degree Corse), Okayama University kn-affil=岡山大学大学院教育学研究科大学院生 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=3 en-affil=Hyogo University of Teacher Education kn-affil=兵庫教育大学大学院学校教育研究科 en-keyword=菌類 (Fungus) kn-keyword=菌類 (Fungus) en-keyword=菌根菌 (Mycorrhizal Fungi) kn-keyword=菌根菌 (Mycorrhizal Fungi) en-keyword=腐生菌 (Saprobic Fungi) kn-keyword=腐生菌 (Saprobic Fungi) en-keyword=相利共生 (Symbiosis) kn-keyword=相利共生 (Symbiosis) en-keyword=教材史 (History of teaching materials) kn-keyword=教材史 (History of teaching materials) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=91 end-page=105 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Reflections of Early Care and Education Practitioners, as Indicated in the Content on the Care and Education of Kindergarten Children Published by Japan’s Ministry of Education, Culture, Sports, Science and Technology kn-title=幼稚園の保育全体に関する文部科学省公表資料に示されている保育者の振り返りの仕方の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　本研究では，まず，我が国の保育施設におけるカリキュラム・マネジメントに関する先行研究を概観し，カリキュラム・マネジメントを実現するために必要な，保育の目標・ねらい・内容の連関性の確保された全体的計画の作成が困難な状況にあることを確認した。続いて，保育の目標・ねらい・内容の連関性を確保する上で，そのことを可能にする保育者の振り返りの仕方が不可欠となることを踏まえて，幼稚園の保育全体に関する文部科学省公表資料に示されている，保育者の振り返りの目的，観点，方法を抽出し整理し，検討した。その結果，保育者の長期の振り返りに関して示されている記述では，具体性が乏しく，保育の目標・ねらい・内容の連関性の確保された長期指導計画及び全体的計画を作成する上で，実用的ではないことを明らかにした。 en-copyright= kn-copyright= en-aut-name=ARITASho en-aut-sei=ARITA en-aut-mei=Sho kn-aut-name=有田翔 kn-aut-sei=有田 kn-aut-mei=翔 aut-affil-num=1 ORCID= en-aut-name=YOKOMATSUTomoyoshi en-aut-sei=YOKOMATSU en-aut-mei=Tomoyoshi kn-aut-name=横松友義 kn-aut-sei=横松 kn-aut-mei=友義 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University (Master’s Course) kn-affil=岡山大学大学院教育学研究科大学院生 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=保育者の振り返り (reflections of early care and education practitioners) kn-keyword=保育者の振り返り (reflections of early care and education practitioners) en-keyword=幼稚園 (kindergarten) kn-keyword=幼稚園 (kindergarten) en-keyword=カリキュラム・マネジメント (curriculum management) kn-keyword=カリキュラム・マネジメント (curriculum management) en-keyword=文部科学省公表資料 (the content on the care and education of kindergarten children published by Japan’s Ministry of Education, Culture, Sports, Science and Technology) kn-keyword=文部科学省公表資料 (the content on the care and education of kindergarten children published by Japan’s Ministry of Education, Culture, Sports, Science and Technology) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=75 end-page=89 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Trends in Awareness of Earthquake Disaster Prevention among Students Aspiring to Become Childcare Providers kn-title=保育者志望学生の地震防災に対する意識の傾向 en-subtitle= kn-subtitle= en-abstract=　In recent years, under the growing sense of crisis about the possibility of a major earthquake in the Nankai Trough, etc., it has become necessary to have more awareness of earthquake disaster prevention and to take measures for disaster prevention regularly. The purpose of this study was to clarify the actual situation of students who aspire to become childcare providers to protect children's lives. As a result of a questionnaire survey, we found that their awareness of the danger of earthquakes tended to differ by grade level and that their understanding and knowledge of earthquake disaster prevention differed depending on their awareness of earthquake disaster prevention. In the future, it will be necessary to consider conducting evacuation drills in kindergartens or nursery schools and providing guidance on disaster prevention education in training programs for childcare providers. kn-abstract=　近年，南海トラフ巨大地震や都市直下型地震に対する危機感が高まる中，地震防災に対する高い意識を持ち，普段から防災に関する取り組みに努めることが求められている。本研究では，子どもの命を守る保育者を目指す志望学生が，地震災害に対する意識をどのように持ち，地震防災に関する知識や理解をどの程度保持しているのかについて，その実態を明らかにすることを目的とした。保育者養成校４大学の学生に対する質問紙調査を行った結果，地震への危機意識が学年によって異なる傾向にあることや，地震防災に関する意識の高低によって，地震に対する知識や認識の違いがあることが判明した。今後，幼児教育・保育施設における避難訓練の実施や，保育者養成課程において防災教育に関する指導を検討していくことが求められる。 en-copyright= kn-copyright= en-aut-name=SATOHDaisuke en-aut-sei=SATOH en-aut-mei=Daisuke kn-aut-name=佐藤大介 kn-aut-sei=佐藤 kn-aut-mei=大介 aut-affil-num=1 ORCID= en-aut-name=TAKAHASHIKei en-aut-sei=TAKAHASHI en-aut-mei=Kei kn-aut-name=髙橋慧 kn-aut-sei=髙橋 kn-aut-mei=慧 aut-affil-num=2 ORCID= en-aut-name=BABANoriko en-aut-sei=BABA en-aut-mei=Noriko kn-aut-name=馬場訓子 kn-aut-sei=馬場 kn-aut-mei=訓子 aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Health and Welfare, Kawasaki University of Medical Welfare kn-affil=川崎医療福祉大学医療福祉学部 affil-num=2 en-affil=Faculty of Childhood Education, Kurashiki Sakuyo University kn-affil=くらしき作陽大学子ども教育学部 affil-num=3 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=地震防災 (earthquake disaster prevention) kn-keyword=地震防災 (earthquake disaster prevention) en-keyword=保育者志望学生 (students aspiring to become childcare providers) kn-keyword=保育者志望学生 (students aspiring to become childcare providers) en-keyword=意識調査 (questionnaire survey) kn-keyword=意識調査 (questionnaire survey) en-keyword=危機意識 (sense of crisis) kn-keyword=危機意識 (sense of crisis) en-keyword=地震防災教育 (education for earthquake disaster prevention) kn-keyword=地震防災教育 (education for earthquake disaster prevention) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=45 end-page=58 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Childcare and Support in Nursery Schools for the Development of Geometry and Number Sense for Five-Year-Old Children kn-title=５歳児を対象とした数量・図形感覚を育む保育所保育の実際と援助の在り方 en-subtitle= kn-subtitle= en-abstract=This study focuses on “the interest and sense of numbers, geometry, and words”, which is regarded as one of "the Ideal Image by the End of Childhood". The focus is on 5-year-old pre-schoolers and their experiences with numbers and shapes in daily lives and games at nursery schools with a comparison with the mathematics classes in the first grade of elementary school. We also aim to provide insights for nursery schools on how to arouse children’s interest and support them to get familiar with geometry and numbers through games.
Our finding reveals that children naturally become familiar with geometry and numbers in their daily lives and their experiences become the foundation when they cope with elementary school mathematics. We also come to know that nursery teachers have to visualize the connection between their games with elementary school mathematics and actively arouse children’s interests and understanding. kn-abstract=　本研究では、幼児期の終わりまでに育って欲しい10の姿のひとつである、「数量・図形、文字等への関心・感覚」に着目し、就学前の５歳児に焦点を当て、保育所の日常生活や遊びにおいて子どもがどのような数量・図形に関する事柄を経験しているのか、また、その経験を小学校１年生の算数科の学習内容と照らして検討した。さらに、子どもが園生活や遊びの中で数量・図形に関心をもって親しみ、学びを得ることを支える保育の在り方について検討した。
　その結果、子どもは日常の中で主体的に数量・図形に親しむ経験をすると共に、その経験が小学校算数科の内容に連続する学びの基礎となっていることが明らかになった。また、保育士自身が小学校算数との繋がりを見通しながら、眼前の子どもの興味や関心に沿って援助することが専門的力量として求められることが示唆された。 en-copyright= kn-copyright=

to evaluate the effectiveness of combining initial hemoglobin levels with the shock index for predicting the need for life-saving interventions (LSI) in pediatric patients with blunt liver and spleen injuries (BLSI), specifically tailored to different age groups. This was a multicenter retrospective cohort study of pediatric patients with BLSI in Japan. The area under the receiver operating characteristic curve (AUROC) were used to assess predictive accuracy. The study included 1,370 patients. LSI was required in 59 of 247 (23.9%) aged 1 to 6 years, 100 of 402 (24.9%) aged 7 to 12 years, and 125 of 297 (42.1%) patients aged 13 to 16 years. Within each specific age group, the predictability was categorized as fair and appeared higher than that of the entire cohort or when using either parameter alone. Notably, in the 1 to 6-year age group, the combined values showed the highest predictability, which was statistically superior to the shock index alone (AUROC of 0.770 vs. 0.671, P = 0.025). Tailoring initial hemoglobin levels and shock index to specific age groups enhances predictability of LSI in pediatric BLSI, showing a fair level of predictive accuracy. en-copyright= kn-copyright=

Today, unlike the attraction of heavy, large-scale industries during the period of high economic growth, there is a trend to attract companies by making the most of the region's advantages. Although the job creation effect has become smaller than in the past, many manufacturing industries remain positioned as core industries in the region. During the first period of regional revitalization, we identify what manufacturing firms have disappeared, withdrawn, appeared, or survived in what regions, and analyze the factors behind those.
　Comparing manufacturing firms in 2014 and 2019, the average of value-added and the distribution of that shows that manufacturing firms that existed in both 2014 and 2019 had the highest labor productivity. The next highest was manufacturing firms that existed in 2019, and the lowest was manufacturing firms that existed in 2014 but did not exist in 2019. In addition, the results of the logit analysis suggest that manufacturing firms with high productivity and large size tend not to disappear, and that manufacturing firms with a high degree of urbanization tend to disappear. On the other hand, a regression analysis at the city/town/village level using industry concentration by industry and urban concentration measured by population size as explanatory variables showed a positive effect on the number of manufacturing firms that had been established. kn-abstract=　地方に位置する多くの自治体においては，従来からある事業所の活性化や新規事業所の誕生に加えて，製造工場の誘致は地域振興にとっていまも重要な政策となっている。今日，高度経済成長期における重厚長大型の産業の誘致とは異なり，地域優位性をできるだけ活用した企業誘致の傾向になっている。雇用創出効果は昔に比べて小さくなっているとはいえ，製造業の多くにおいて，地域の基盤産業としての位置づけは残っている。第1期の地方創生の期間で，どのような地域において，どのような製造工場が消失，撤退や出現，存続しているのかを識別し，それらの要因を分析する。
　2014年と2019年の事業所の比較において，付加価値生産性の平均と分布を見ると2014年，2019年ともに存在する事業所の労働生産性が最も高い。次いで高いのが2019年に存在する事業所で，最も低かったのが2014年には存在したが2019年には存在していない事業所であった。またロジット分析の結果から，生産性が高く事業所規模が大きいと消滅しない傾向があり，また都市化の程度が高いと消滅傾向にあることが推定された。他方，発生した製造事業所について，産業別に同業種集積と人口規模で測った都市集積を説明変数とした市町村単位の回帰分析からは正の効果が示された。 en-copyright= kn-copyright= en-aut-name=NakamuraRyohei en-aut-sei=Nakamura en-aut-mei=Ryohei kn-aut-name=中村良平 kn-aut-sei=中村 kn-aut-mei=良平 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue=3 article-no= start-page=1 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250321 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Market Segmentation and Market Reactions to Earnings Announcements: A Quarterly Analysis kn-title=市場区分と決算発表に対する市場の反応 ―四半期データを利用した分析― en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this paper is to examine, using quarterly financial data, how the market reaction to earnings announcements in each market segment （prime market segment, standard market segment, and growth market segment） has changed after the revision of market segmentation at the Tokyo Stock Exchange. For the research design, the abnormal volume and residual returns for the 12 quarters around April 1, 2022, when the market segmentation was changed, were calculated using the analysis method of Beaver et al. ［2020］. The results of the analysis suggest that volume is significantly affected by changes in market segmentation. In addition, for the group of stocks in the growth market, there appears to have been some change in the trend of stock price fluctuations after the market segmentation revision. en-copyright= kn-copyright= en-aut-name=NakagawaToyotaka en-aut-sei=Nakagawa en-aut-mei=Toyotaka kn-aut-name=中川豊隆 kn-aut-sei=中川 kn-aut-mei=豊隆 aut-affil-num=1 ORCID= en-aut-name=YamanishiYuki en-aut-sei=Yamanishi en-aut-mei=Yuki kn-aut-name=山西佑季 kn-aut-sei=山西 kn-aut-mei=佑季 aut-affil-num=2 ORCID= en-aut-name=KobayashiHiroaki en-aut-sei=Kobayashi en-aut-mei=Hiroaki kn-aut-name=小林裕明 kn-aut-sei=小林 kn-aut-mei=裕明 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil=熊本県立大学総合管理学部 affil-num=3 en-affil= kn-affil=青山学院大学大学院会計プロフェッション研究科 END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=36 end-page=43 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=2025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of the temporal behavior of fulvic acid iron in Asahi River, Okayama, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Iron is essential for biogeochemical processes in aquatic ecosystems, but its riverine concentration can be affected by environmental conditions. This study assessed weekly fulvic acid iron (FAFe) concentration at a single sampling site in Asahi River from 2022–2023 to explore the differences in the temporal scales. The objectives of this study were to evaluate the effects of physicochemical properties of the river on the concentration of FAFe, analyze the concentration of FAFe in spring, summer, autumn and winter, and assess the relationship between FAFe concentration and land use types of the watershed. The results indicated that physicochemical parameters, such as pH and surface water temperature (SWT) seemed to influence FAFe concentration (p < 0.05). Hydrological dynamics influenced FAFe concentration and transport, revealing an increasing trend during spring (p < 0.001) and summer (p = 0.05), with non-significant trends during autumn and winter (p > 0.05). FAFe exhibited a strong positive correlation with total organic carbon (TOC) (p < 0.001). Upland fields significantly influenced FAFe concentration (p < 0.01) through runoff with abundant NO3– and PO43– into the river. Thus, FAFe concentration in Asahi River was influenced by pH, SWT, TOC, hydrological regime, and agricultural runoff. en-copyright= kn-copyright= en-aut-name=YengehRohdof Lactem en-aut-sei=Yengeh en-aut-mei=Rohdof Lactem kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SomuraHiroaki en-aut-sei=Somura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoroizumiToshitsugu en-aut-sei=Moroizumi en-aut-mei=Toshitsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriYasushi en-aut-sei=Mori en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MaedaMorihiro en-aut-sei=Maeda en-aut-mei=Morihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=dissolved iron kn-keyword=dissolved iron en-keyword=seasonal variation kn-keyword=seasonal variation en-keyword=dissolved organic matter kn-keyword=dissolved organic matter en-keyword=fulvic acid iron kn-keyword=fulvic acid iron END start-ver=1.4 cd-journal=joma no-vol=188 cd-vols= no-issue= article-no= start-page=123 end-page=127 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Review of Research on Digital Media Usage in Japanese Infancy kn-title=乳幼児期におけるデジタルメディア使用状況に関する研究の概観 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　子どものデジタルメディア，デジタルデバイスの使用に関して，使用開始年齢の低年齢化・長時間利用の問題が指摘され，乳幼児期からの使用実態の把握やそれが発達に及ぼす影響，および親の使用実態やペアレンタルコントロールも含めた検討の必要性が高まっているといえる。本報告では，近年の本邦における乳幼児を対象としたデジタルメディア，デジタルデバイスの使用実態を報告する研究や報告書を概観し，乳幼児期における使用実態の概要を把握するとともに，乳幼児期における依存傾向の実態やデジタルメディア使用に対する親の認識，乳幼児期のデジタルメディア使用をめぐるその他のトピックについて概観した。 en-copyright= kn-copyright= en-aut-name=MIYAKEMotoko en-aut-sei=MIYAKE en-aut-mei=Motoko kn-aut-name=三宅幹子 kn-aut-sei=三宅 kn-aut-mei=幹子 aut-affil-num=1 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=デジタルメディア kn-keyword=デジタルメディア en-keyword=デジタルデバイス kn-keyword=デジタルデバイス en-keyword=乳幼児期 kn-keyword=乳幼児期 en-keyword=ペアレンタルコントロール kn-keyword=ペアレンタルコントロール END start-ver=1.4 cd-journal=joma no-vol=188 cd-vols= no-issue= article-no= start-page=115 end-page=121 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Study on the Transition and Interpretation of Yasuo Kuniyoshi’s Works within Japan kn-title=日本国内における国吉康雄作品の捉え方の変遷と解釈についての考察 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　洋画家・国吉康雄 (1889-1953) は、岡山市北区出石町に生まれ，日露戦争終結後の1906 年に労働移民として単身渡米し，アメリカの教育により画家としての才能を磨き，20 世紀前半のアメリカを代表する画家として評価される洋画家・国吉康雄（1889-1953）。本論では，その画業と作品評価について論じるわが国の研究者の記述を，作家の没後の1954 年に国立近代美術館（現国立東京近代美術館）で開催された「国吉康雄遺作展」を起点とし，20 世紀中に開催された主な展覧会と，2004 年に同じく東京国立近代美術館などで開催された「国吉康雄展」で確認した。結果，日本人による国吉作品の表現が，この1954 年時に決定づけられていることに，別の捉え方を提示されるまでに40 年の歳月を要していることが明らかとなった。 en-copyright= kn-copyright= en-aut-name=ITOShun en-aut-sei=ITO en-aut-mei=Shun kn-aut-name=伊藤駿 kn-aut-sei=伊藤 kn-aut-mei=駿 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Yasuo Kuniyoshi Studies : Art Education and Rural Reveitalization,Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科国吉康雄記念・美術教育研究と地域創生講座 en-keyword=国吉康雄 kn-keyword=国吉康雄 en-keyword=作品解釈 kn-keyword=作品解釈 en-keyword=日系アメリカ人アーティスト kn-keyword=日系アメリカ人アーティスト en-keyword=展覧会 kn-keyword=展覧会 END start-ver=1.4 cd-journal=joma no-vol=188 cd-vols= no-issue= article-no= start-page=105 end-page=114 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Reconsidering Students’ Views of Home Economics through Comparison with Other Subjects: Through an Examination of the Explanation of the Curriculum Guidelines for “Secondary Home Economics Education” kn-title=学生による家庭科と他教科の比較を通した教科観の再考 ―「 中等家庭科教育法」における学習指導要領解説の検討を通して ― en-subtitle= kn-subtitle= en-abstract= kn-abstract=　本稿では，中等家庭科教員養成課程に在籍する２年生の必修科目「中等家庭科教育法」において，家庭科と他教科を比較（共通点や相違点を整理）する機会を設けることで，受講した学生の家庭科に対する教科観がどのように変容するのかを調査することを目的とした。

The species complex is divided into 13 anastomosis groups (AGs) based on hyphal fusion compatibility and further subdivided by culture morphology. While R. solani classifications were shown to be independent of host specificity, it remains unclear whether different R. solani isolates share similar virulence mechanisms. Here, we investigated the infectivity of Japanese R. solani isolates on Brachypodium distachyon and barley. Two isolates, AG-1 IA (from rice) and AG-4 HG-I+II (from cauliflower), infected leaves of both plants, but only AG-4 HG-I+II infected roots. B. distachyon accessions Bd3-1 and Gaz-4 and barley cultivar 'Morex' exhibited enhanced resistance to both isolates compared to B. distachyon Bd21 and barley cultivars 'Haruna Nijo' and 'Golden Promise'. During AG-1 IA infection, but not AG-4 HG-I+II infection, resistant Bd3-1 and Morex induced genes for salicylic acid (SA) and N-hydroxypipecolic acid (NHP) biosynthesis. Pretreatment with SA or NHP conferred resistance to AG-1 IA, but not AG-4 HG-I+II, in susceptible B. distachyon Bd21 and barley Haruna Nijo. On the leaves of susceptible Bd21 and Haruna Nijo, AG-1 IA developed extensive mycelial networks with numerous infection cushions, which are specialized infection structures well-characterized in rice sheath blight. In contrast, AG-4 HG-I+II formed dispersed mycelial masses associated with underlying necrosis. We propose that the R. solani species complex encompasses at least two distinct infection strategies: AG-1 IA exhibits a hemibiotrophic lifestyle, while AG-4 HG-I+II follows a predominantly necrotrophic strategy. en-copyright= kn-copyright= en-aut-name=MahadevanNiranjan en-aut-sei=Mahadevan en-aut-mei=Niranjan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FernandaRozi en-aut-sei=Fernanda en-aut-mei=Rozi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KouzaiYusuke en-aut-sei=Kouzai en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KohnoNatsuka en-aut-sei=Kohno en-aut-mei=Natsuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NagaoReiko en-aut-sei=Nagao en-aut-mei=Reiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NyeinKhin Thida en-aut-sei=Nyein en-aut-mei=Khin Thida kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatanabeMegumi en-aut-sei=Watanabe en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakataNanami en-aut-sei=Sakata en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MatsuiHidenori en-aut-sei=Matsui en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IchinoseYuki en-aut-sei=Ichinose en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MochidaKeiichi en-aut-sei=Mochida en-aut-mei=Keiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=HisanoHiroshi en-aut-sei=Hisano en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=NoutoshiYoshiteru en-aut-sei=Noutoshi en-aut-mei=Yoshiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Crop Stress Management Group, Division of Plant Molecular Regulation Research, Institute of Agrobiological Sciences, National Agriculture and Food Research Organization (NARO) kn-affil= affil-num=4 en-affil=Faculty of Agriculture, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Agriculture, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=12 en-affil=RIKEN Center for Sustainable Resource Science kn-affil= affil-num=13 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=14 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Rhizoctonia solani species complex kn-keyword=Rhizoctonia solani species complex en-keyword=virulence mechanism kn-keyword=virulence mechanism en-keyword=infection behavior kn-keyword=infection behavior en-keyword=salicylic acid kn-keyword=salicylic acid en-keyword=N-hydroxypipecolic acid kn-keyword=N-hydroxypipecolic acid END start-ver=1.4 cd-journal=joma no-vol=197 cd-vols= no-issue= article-no= start-page=115301 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fraglide-1 from traditional Chinese aromatic vinegar: A natural AhR antagonist for atopic dermatitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Traditional Chinese Zhenjiang aromatic vinegar (Kozu) contains Fraglide-1 (FG1), a bioactive lactone with demonstrated peroxisome proliferator-activated receptor gamma (PPARγ) agonist and antioxidant activities. This study explored FG1's novel ability to antagonize the aryl hydrocarbon receptor (AhR) signaling pathway, which regulates artemin expression and contributes to itching and inflammation in atopic dermatitis. Through molecular docking simulations and cell-based assays in human keratinocytes, we demonstrated FG1's potent antagonistic activity against AhR signaling. FG1 effectively suppressed FICZ-induced inflammatory responses, including artemin expression, with potency (half maximal inhibitory concentration, IC50 = 5.1 μM) comparable to the synthetic antagonist StemRegenin 1 (SR1) while demonstrating a superior safety profile (median lethal concentration, LC50 > 100 μM vs. 27.5 μM for SR1). These findings expand our understanding of bioactive compounds from traditional fermented foods and their regulatory effects on AhR signaling, providing a foundation for future studies on FG1's role in modulating skin inflammation. en-copyright= kn-copyright= en-aut-name=KatoKosuke en-aut-sei=Kato en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AkamatsuMiki en-aut-sei=Akamatsu en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KakimaruSaya en-aut-sei=Kakimaru en-aut-mei=Saya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoreishiMayuko en-aut-sei=Koreishi en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakagiMasahiro en-aut-sei=Takagi en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyashitaMasahiro en-aut-sei=Miyashita en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MurataYoshiyuki en-aut-sei=Murata en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraYoshimasa en-aut-sei=Nakamura en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SatohAyano en-aut-sei=Satoh en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TsujinoYoshio en-aut-sei=Tsujino en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=5 en-affil=School of Materials Science, Japan Advanced Institute of Science and Technology kn-affil= affil-num=6 en-affil=Graduate School of Agriculture, Kyoto University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=9 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=10 en-affil=Graduate School of Science, Technology and Innovation, Kobe University kn-affil= en-keyword=AhR kn-keyword=AhR en-keyword=Xenobiotic responsive element kn-keyword=Xenobiotic responsive element en-keyword=StemRegenin 1 kn-keyword=StemRegenin 1 en-keyword=ARNT kn-keyword=ARNT en-keyword=Atopic dermatitis kn-keyword=Atopic dermatitis en-keyword=Artemin kn-keyword=Artemin END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=1 article-no= start-page=3 end-page=10 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Investigation of SNPs associated with reproductive and body growth traits in Vietnamese and Nepalese native buffaloes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Water buffaloes are essential to the rural economies of many developing countries, including Vietnam and Nepal, but native buffalo populations in these countries face challenges such as low productivity due to fertility and body growth issues. This study analyzed 34 SNPs in 18 genes associated with reproductive and body growth traits reported in cattle and buffalo in Vietnamese and Nepalese native buffaloes. Results showed no polymorphism at bovine SNPs in either buffalo. Further analysis with SNPs previously reported only in popular buffalo breeds, such as Murrah, found that Vietnamese buffalo were monomorphic at all sites, which may reflect reduced genetic diversity due to population decline. In contrast, Nepalese buffalo, consisting of two native breeds, showed polymorphism in 11 SNPs in 7 genes, with 10 of these matching those found in the Murrah buffalo analyzed here. These findings suggest that these SNPs may be applicable for genetic improvement in Nepalese native buffalo. This study provides valuable insights for future conservation and breeding programs aimed at enhancing reproductive and body growth performance of native buffalo in Vietnam and Nepal. en-copyright= kn-copyright= en-aut-name=Thuy ThanhNguyen en-aut-sei=Thuy Thanh en-aut-mei=Nguyen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KuniedaTetsuo en-aut-sei=Kunieda en-aut-mei=Tetsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Manoj KumarShah en-aut-sei=Manoj Kumar en-aut-mei=Shah kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Thu Nu AnhLe en-aut-sei=Thu Nu Anh en-aut-mei=Le kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=Van HuuNguyen en-aut-sei=Van Huu en-aut-mei=Nguyen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UshijimaKoichiro en-aut-sei=Ushijima en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NagaeMayuko en-aut-sei=Nagae en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsujiTakehito en-aut-sei=Tsuji en-aut-mei=Takehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=National Swine Research Program kn-affil= affil-num=4 en-affil=Faculty of Animal Sciences and Veterinary Medicine, University of Agriculture and Forestry, Hue University kn-affil= affil-num=5 en-affil=Faculty of Animal Sciences and Veterinary Medicine, University of Agriculture and Forestry, Hue University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Vietnamese native buffalo kn-keyword=Vietnamese native buffalo en-keyword=Nepalese native buffalo kn-keyword=Nepalese native buffalo en-keyword=SNPs kn-keyword=SNPs en-keyword=Reproduction kn-keyword=Reproduction en-keyword=Body growth kn-keyword=Body growth END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=16 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250215 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Behavior, behavioral syndromes, and metabolism: the effects of artificial selection for death-feigning on metabolic rate en-subtitle= kn-subtitle= en-abstract= kn-abstract=Death-feigning, or thanatosis, is an anti-predator behavioral strategy in many animals. Because individuals remain immobile while feigning death, individuals with longer durations of death feigning often show lower locomotor activity. Thus, metabolic rate, which is closely related to locomotor activity, may also be related to the intensity of death feigning. If there is a genetic correlation between death feigning and metabolism, metabolic rate may respond to selection on death-feigning behavior. Here, we tested for a relationship between metabolic rate and death-feigning using replicated populations of the red flour beetle (Tribolium castaneum) subjected to artificial bidirectional selection on the duration of death-feigning behavior. The results indicated that metabolic rate did not differ between populations selected for increased or decreased death feigning, although locomotor activity was significantly different between these treatments; populations selected for reduced death-feigning durations tended to be more active. These results suggest that death-feigning behavior is not genetically correlated with metabolic rate in T. castaneum. en-copyright= kn-copyright= en-aut-name=MatsumuraKentarou en-aut-sei=Matsumura en-aut-mei=Kentarou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HoskenDavid J. en-aut-sei=Hosken en-aut-mei=David J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NodaTomohito en-aut-sei=Noda en-aut-mei=Tomohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SharmaManmohan D. en-aut-sei=Sharma en-aut-mei=Manmohan D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Centre for Ecology and Conservation, Faculty of Environment, Science and Economy, University of Exeter kn-affil= affil-num=3 en-affil=Centre for Ecology and Conservation, Faculty of Environment, Science and Economy, University of Exeter kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Centre for Ecology and Conservation, Faculty of Environment, Science and Economy, University of Exeter kn-affil= en-keyword=anti-predator behavior kn-keyword=anti-predator behavior en-keyword=artificial selection kn-keyword=artificial selection en-keyword=death-feigning kn-keyword=death-feigning en-keyword=metabolic rate kn-keyword=metabolic rate en-keyword=personality kn-keyword=personality en-keyword=Tribolium kn-keyword=Tribolium END start-ver=1.4 cd-journal=joma no-vol=236 cd-vols= no-issue= article-no= start-page=74 end-page=81 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characteristics of porcine oocyte-cumulus complexes derived from various sizes of antral follicles and classified by brilliant cresyl blue staining, and developmental competence of the oocytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=The present study sought to determine the characteristics of porcine oocyte-cumulus complexes (OCCs) derived from very small and small antral follicles (with less than 1 mm and 1–3 mm in diameter, respectively; VSF and SF) in comparison with controls from medium ones (with 3–6 mm in diameter; MF). Additionally, the present study examined the utility of brilliant cresyl blue (BCB) staining for assessing these OCCs. The incidence of BCB- oocytes in VSF- and SF-derived OCCs was higher than that in MF-derived OCCs. Although the meiotic and developmental competences of BCB+ oocytes from MF were superior to those from VSF and SF, blastocysts were successfully obtained from BCB+ oocytes even derived from VSF. The mean numbers of both total and viable cumulus cells surrounding an oocyte were significantly affected not only by the origin of the OCCs, but also by the BCB status of the oocytes (largest in MF-derived OCCs containing BCB+ oocytes). Although the outer and inner diameters of zona pellucida were affected by the origin of OCCs and the BCB status of oocytes (largest in MF-derived oocytes), the ooplasmic diameter of BCB+ oocytes did not differ among those derived from VSF, SF, and MF. Regardless of the BCB status, the transcriptional levels of G6PD and TKT in cumulus cells decreased during follicular development from VSF to MF, whereas the RPIA mRNA level in cumulus cells of MF-derived BCB+ OCCs was lower than in the others. These results underscore the utility of BCB staining for selecting MF-, SF-, and even VSF-derived OCCs containing oocytes with relatively higher meiotic and developmental competences, as well as the importance of having a sufficient number of healthy cumulus cells expressing genes related to the pentose phosphate pathway at lower levels. en-copyright= kn-copyright= en-aut-name=VanPhong Ngoc en-aut-sei=Van en-aut-mei=Phong Ngoc kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DoSon Quang en-aut-sei=Do en-aut-mei=Son Quang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FonsekaWanniarachchige Tharindu Lakshitha en-aut-sei=Fonseka en-aut-mei=Wanniarachchige Tharindu Lakshitha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WakaiTakuya en-aut-sei=Wakai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FunahashiHiroaki en-aut-sei=Funahashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=234 cd-vols= no-issue= article-no= start-page=125 end-page=132 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Mitochondrial content and mtDNA copy number in spermatozoa and penetrability into oocytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=The current narrative review aims to summarize the relation of mitochondrial content (MC) and mitochondrial DNA copy number (MDCN) in spermatozoa with sperm penetrability, and to discuss the various determining factors during the process of spermatogenesis in mammals. There are many potential factors associated with the quantitative alteration of MC and MDCN in male gametes from spermatogenesis to ejaculation. Particularly, spermatogenesis may be the first step to jointly contribute to an incomplete reduction of MC and MDCN in spermatozoon. It appears to be now quite clear that some abnormalities during spermatogenesis and oxidative stress are the main factors highly associated with the quantitative change of MC and MDCN in spermatozoa, consequently affecting sperm quality and their penetrability into oocytes. Currently, a series of proteins contributing to form sperm midpiece during spermatogenesis and cytoplasmic elimination during spermiation have been currently identified. The present review provides insight into how these factors interact with sperm MC and MDCN, and handholds to gain a better understanding of their roles. This review also highlights the uniqueness of normal fertile spermatozoa which have relatively lower MC and MDCN, but have mitochondria that function completely in multiple pivotal physiological pathways. en-copyright= kn-copyright= en-aut-name=NguyenHai Thanh en-aut-sei=Nguyen en-aut-mei=Hai Thanh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DoSon Quang en-aut-sei=Do en-aut-mei=Son Quang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WakaiTakuya en-aut-sei=Wakai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FunahashiHiroaki en-aut-sei=Funahashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Animal Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Animal Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Animal Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Animal Science, Okayama University kn-affil= en-keyword=Spermatozoa kn-keyword=Spermatozoa en-keyword=Mitochondria kn-keyword=Mitochondria en-keyword=Mitochondrial DNA kn-keyword=Mitochondrial DNA en-keyword=Penetrability kn-keyword=Penetrability en-keyword=Spermatogenesis kn-keyword=Spermatogenesis END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250209 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of caffeine on the longevity and locomotion activity of the common green bottle fly, Lucilia sericata (Diptera: Calliphoridae) en-subtitle= kn-subtitle= en-abstract= kn-abstract=The common green bottle fly, Lucilia sericata (Meigen) (Diptera: Calliphoridae), is a promising and useful managed pollinator for greenhouse agricultural crops. The fly can pollinate at lower and higher temperatures than European honeybee. However, management of the longevity of pollinators is important for growers using greenhouses. Previous studies using other insects showed that caffeine affects insect longevity and behaviors. For instance, European honeybee live longer and have increased memory after caffeine consumption. How caffeine affects the longevity and behavior of pollinators is worth investigating because it can affect pollinator’s behavior, extend longevity, or be an insecticide against pollinators. In the present study, therefore, the longevity and locomotion of L. sericata were investigated when they were given different caffeine concentrations. First, the longevity of L. sericata with five different caffeine concentrations was compared to the control. The results showed that higher concentrations of caffeine (2%, 1%, and 0.5%) significantly decreased the life span compared to lower concentrations (0.05% and 0.01%). Second, the locomotion activities of L. sericata were examined at those two caffeine concentrations with treated and control male and female flies utilizing a Drosophila Activity Monitor (DAM). Treatment with 0.05% caffeine dramatically reduced locomotion, but treatment of 0.01% caffeine did not. We also compared lipid concentrations of flies: flies treated with 0.05% caffeine had a lower lipid concentration compared to flies treated with 0% and 0.01% caffeine. These results indicate that caffeine had negative effects on the longevity and locomotion activities of the pollinator L. sericata in laboratory conditions. en-copyright= kn-copyright= en-aut-name=NaingShine Shane en-aut-sei=Naing en-aut-mei=Shine Shane kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiokaHaruna en-aut-sei=Fujioka en-aut-mei=Haruna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuuraTeruhisa en-aut-sei=Matsuura en-aut-mei=Teruhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Caffeine kn-keyword=Caffeine en-keyword=Life span kn-keyword=Life span en-keyword=Locomotor activity kn-keyword=Locomotor activity en-keyword=Pollinator kn-keyword=Pollinator END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=2485 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250120 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cesarean delivery on child health and development in Japanese nationwide birth cohort en-subtitle= kn-subtitle= en-abstract= kn-abstract=The long-term effects of cesarean delivery (CD) on child health and development remain controversial. This study aimed to investigate these effects using an outcome-wide approach in a Japanese context, where perinatal mortality rates are among the world's lowest. We analyzed data from 2,114 children in a nationwide Japanese birth cohort, linking the 21st Century Longitudinal Survey of Newborns with the Perinatal Research Network database. We examined associations between CD and various health and developmental outcomes up to 9 years of age, including hospitalizations, obesity, and developmental milestones. After adjusting for potential confounders, CD was not significantly associated with most outcomes, including all-cause hospitalization (adjusted risk ratio 1.25, 95% CI 0.997-1.56), obesity at 5.5 and 9 years, and various developmental milestones. Subgroup analyses for multiple births and preterm infants showed some differences in point estimates, but were limited by small sample sizes. CD was not significantly associated with adverse long-term child health or developmental outcomes in this Japanese cohort. These findings provide reassurance regarding CD safety when medically indicated in advanced perinatal care settings. Further research with larger samples and longer follow-up is needed, especially for specific subgroups. en-copyright= kn-copyright= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuiTakashi en-aut-sei=Mitsui en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TamaiKei en-aut-sei=Tamai en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirotaTomoya en-aut-sei=Hirota en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasuyamaHisashi en-aut-sei=Masuyama en-aut-mei=Hisashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Division of Neonatology, NHO Okayama Medical Center kn-affil= affil-num=4 en-affil=Department of Psychiatry and Behavioral Sciences, UCSF Weill Institute for Neurosciences, University of California San Francisco kn-affil= affil-num=5 en-affil=Department of Obstetrics and Gynecology, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Cesarean delivery kn-keyword=Cesarean delivery en-keyword=Delivery methods kn-keyword=Delivery methods en-keyword=Long-term outcome kn-keyword=Long-term outcome en-keyword=Child development kn-keyword=Child development en-keyword=Outcome-wide approach kn-keyword=Outcome-wide approach END start-ver=1.4 cd-journal=joma no-vol=114 cd-vols= no-issue= article-no= start-page=27 end-page=38 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The List of Published by Members of the Faculty From January to December 2024. kn-title=公表学術論文等リスト　2024 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=114 cd-vols= no-issue= article-no= start-page=11 end-page=20 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Uncovering the role of arcuate kisspeptin neurons as a source of the gonadotropin-releasing hormone pulse generator using gene-modified rats kn-title=遺伝子改変ラットを用いた弓状核キスペプチンニューロンの性腺刺激ホルモン放出ホルモンパルスジェネレーターとしての役割解明 en-subtitle= kn-subtitle= en-abstract=　世界において，乳牛の受胎率（妊娠率）が低下しており，家畜の繁殖成績向上のための効果的な治療法が必要とされている．家畜を含む哺乳類において，生殖機能は視床下部－下垂体－性腺軸から分泌されるホルモンによって制御されている．これらのホルモンのうち，性腺刺激ホルモン放出ホルモン（GnRH）のパルス状分泌（GnRH パルス）は，性腺刺激ホルモン分泌と性腺機能に本質的に重要である．したがって，GnRH パルスを制御するメカニズム（GnRH パルスジェネレーター）を解明することは，家畜の生殖技術を向上させるために不可欠である．本総説では，著者らの遺伝子改変ラットモデルを用いた弓状核キスペプチンニューロン（ΚNDy ニューロンとしても知られる）がGnRH パルスジェネレーターの本体であることの直接的な証拠を示した研究を中心として，過去20年間の研究を概説した．また，ΚNDy ニューロンが分泌するニューロキニンB，グルタミン酸，ダイノルフィンA がΚNDy ニューロンの神経活動を同期させ，GnRH パルスを発生させるメカニズムについて論じた．遺伝子改変ラットモデルから得られた知識は，GnRH/ 性腺刺激ホルモンパルスを刺激して，家畜の繁殖能力を向上させる新規繁殖促進剤開発に寄与すると期待できる． kn-abstract=　Strategies for increasing reproductive performance are needed for domestic animals because for example the conception (pregnancy) rate has decreased in dairy cows around the world. Reproductive function is controlled by hormones released by the hypothalamus-pituitary-gonadal axis in mammals, including domestic animals. Of those hormones, tonic (pulsatile) gonadotropin-releasing hormone (GnRH) release is fundamentally important for gonadotropin release and gonadal activity. Therefore, uncovering the mechanism controlling GnRH pulses, that is GnRH pulse generator, is essential to improve reproductive technologies for domestic animals. The present review is focused on the indispensable role of arcuate nucleus (ARC) kisspeptin neurons (also known as KNDy neurons) as the GnRH pulse generator in mammals. First, we give a brief overview of studies on hypothalamic kisspeptin neurons throughout the past two decades. Second, we review studies that have provided direct evidence that ARC kisspeptin neurons serve as the GnRH pulse generator, with a special focus on our gene-modified rat models. Finally, we discuss the mechanism underlying GnRH pulse generation. The knowledge obtained from gene-modified rat models should be clinically important and could be adapted to new tools to improve reproductive performance in livestock by stimulating GnRH/gonadotropin pulses. en-copyright= kn-copyright= en-aut-name=NagaeMayuko en-aut-sei=Nagae en-aut-mei=Mayuko kn-aut-name=長江麻佑子 kn-aut-sei=長江 kn-aut-mei=麻佑子 aut-affil-num=1 ORCID= en-aut-name=UenoyamaYoshihisa en-aut-sei=Uenoyama en-aut-mei=Yoshihisa kn-aut-name=上野山賀久 kn-aut-sei=上野山 kn-aut-mei=賀久 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学大学院環境生命自然科学研究科 affil-num=2 en-affil=Graduate School of Bioagricultural Sciences, Nagoya University kn-affil=名古屋大学大学院生命農学研究科 en-keyword=gene-modified rats kn-keyword=gene-modified rats en-keyword=GnRH kn-keyword=GnRH en-keyword=kisspeptin kn-keyword=kisspeptin en-keyword=LH kn-keyword=LH en-keyword=pulse generator kn-keyword=pulse generator END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The perception of plastic waste and composition of boathouse waste in floating villages on Tonlé Sap Lake, Cambodia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Villagers living on Tonlé Sap (TS) Lake have low incomes and no access to basic public services, such as waste management, domestic water, electricity, and health care. Knowledge of the villagers’ perceptions and the composition of the waste from their boathouses will contribute to constructing a waste collection system with community participation within the framework of waste prevention and reduction. This study surveyed residents living in boathouses in four floating villages on TS Lake, Cambodia, regarding their perceptions and boathouse waste composition to assess the status of plastic waste and the villagers’ environmental awareness and their willingness to participate in waste collection. The household waste survey sought to clarify the amount of plastic waste and other recyclable waste discharged from floating houses. The perception survey revealed that in the wet season, 36% of respondents disposed of plastic waste by open burning/dumping and 40% by discharge into TS Lake; in the dry season, 76% disposed of waste by open burning/dumping, and only 4% discharged waste into TS Lake. An analysis of the boathouse plastic waste composition showed that residents of the floating villages generated 40.21 g plastic waste/day/capita, which was much lower than 340 g/day/capita in the USA, 120 g/day/capita in China, and even 70 g/day/capita in Cambodian on average, but higher than the 10 g/day/capita in India. This study proposes a novel and valuable framework to estimate and determine the level of awareness of people in floating villages related to plastic pollution effects and waste components from boathouses. At the same time, the research results provide an essential scientific basis to be able to develop an effective waste collection system in the area of TS Lake. The proposed framework of this study will help the policy decision-makers in the TS Lake area and those in similar geographical regions facing similar problems. en-copyright= kn-copyright=

dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Maternal smoking during infancy increases the risk of allergic diseases in children: a nationwide longitudinal survey in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The incidence of allergic diseases has been increasing in Japan. In particular, a serious decline in the age of onset of allergic rhinitis has been observed. Passive smoking from parental smoking has a significant impact on children’s health; however, it is difficult to restrict smoking in the home. While various studies have previously reported on the relationship between passive smoking and the development of allergic diseases in children. However, there have been no reports on passive smoking and allergic diseases on a national scale.
Methods Using Japanese national longitudinal survey data (n = 38,444) for newborns born between May 10 and 24, 2010, we assessed parental smoking habits when their children were 6 months old and investigated the association with the development of allergic diseases until the age of 5.5 years. The risk ratios and 95% confidence intervals for the development of different allergic diseases were analyzed after adjusting for potential confounders using Poisson regression with a robust error variance.
Results The risk ratio for developing allergic rhinitis/allergic conjunctivitis (AR/AC) in children was significantly higher in the maternal smoking groups ( ≦ 10 cigarettes/day; RR 1.15, 95% CI 1.02–1.30; ≧11 cigarettes/day; RR 1.16, 95% CI 0.93–1.44). Furthermore, associations were found between the maternal smoking group in the presence of paternal smoking and the risk of developing bronchial asthma ( ≦ 10, RR 1.33 95% CI 1.17–1.52; ≧11, RR 1.71 95% CI 1.38–2.1), food allergy ( ≦ 10, RR 1.36 95% CI 1.12–1.63; ≧11, RR 1.25 95% CI 0.84–1.86), atopic dermatitis ( ≦ 10, RR 1.42 95% CI 1.22–1.66; ≧11, RR 1.6 95% CI 1.2–2.13), and AR/AC ( ≦ 10, RR 1.21 95% CI 1.07–1.36; ≧11, RR 1.35 95% CI 1.09–1.67).
Conclusions Maternal smoking during infancy increases the risk of developing AR/AC in children. Considering paternal smoking, maternal smoking further increased the risk of developing allergic diseases in children, suggesting that reducing parental smoking at home may reduce the risk of developing allergic diseases in children. en-copyright= kn-copyright= en-aut-name=ShigeharaKenji en-aut-sei=Shigehara en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsugeMitsuru en-aut-sei=Tsuge en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UdaKazuhiro en-aut-sei=Uda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SaitoYukie en-aut-sei=Saito en-aut-mei=Yukie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YashiroMasato en-aut-sei=Yashiro en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IkedaMasanori en-aut-sei=Ikeda en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatric Acute Diseases, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Allergic rhinitis kn-keyword=Allergic rhinitis en-keyword=Bronchial asthma kn-keyword=Bronchial asthma en-keyword=Atopic dermatitis kn-keyword=Atopic dermatitis en-keyword=National cohort study kn-keyword=National cohort study en-keyword=Passive smoking kn-keyword=Passive smoking END start-ver=1.4 cd-journal=joma no-vol=125 cd-vols= no-issue= article-no= start-page=106672 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Resveratrol, a food-derived polyphenol, promotes Melanosomal degradation in skin fibroblasts through coordinated activation of autophagy, lysosomal, and antioxidant pathways en-subtitle= kn-subtitle= en-abstract= kn-abstract=Resveratrol, a polyphenol found in grapes and peanuts, is known for diverse biological activities, yet its effects on dermal hyperpigmentation (so-called dark spots) remain unexplored. We investigated resveratrol's ability to enhance melanosomal degradation in human dermal fibroblasts. At concentrations of 25-50 mu M, resveratrol increased autophagy as measured by microtubule-associated protein 1A/1B-light chain 3 (LC3)-II/LC3-I ratio and enhanced lysosomal activity as assessed by a lysosomal activity reporter system. RNA sequencing revealed upregulation of lysosomal and autophagy-related genes, including cathepsins. Furthermore, reporter assays showed resveratrol's activation of antioxidant response via nuclear factor erythroid 2-related factor 2 (NRF2)mediated, leading to upregulation of transcription factor EB/transcription factor E3 (TFEB/TFE3), master regulators of lysosomal function. In fibroblasts pre-loaded with melanosomes, resveratrol reduced melanosome content compared to control by day 3. The findings reveal the activation of interconnected autophagy, lysosomal, and antioxidant pathways by resveratrol, suggesting potential applications in functional foods targeting dermal hyperpigmentation. en-copyright= kn-copyright= en-aut-name=OkamotoSaki en-aut-sei=Okamoto en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KakimaruSaya en-aut-sei=Kakimaru en-aut-mei=Saya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoreishiMayuko en-aut-sei=Koreishi en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakamotoMika en-aut-sei=Sakamoto en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakamuraYoshimasa en-aut-sei=Nakamura en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AndoHideya en-aut-sei=Ando en-aut-mei=Hideya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsujinoYoshio en-aut-sei=Tsujino en-aut-mei=Yoshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SatohAyano en-aut-sei=Satoh en-aut-mei=Ayano kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=National Institute of Genetics, ROIS kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Department of Applied Chemistry and Biotechnology, Okayama University of Science kn-affil= affil-num=7 en-affil=Graduate School of Science, Technology, and Innovation, Kobe University kn-affil= affil-num=8 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Antioxidant kn-keyword=Antioxidant en-keyword=Lysosomes kn-keyword=Lysosomes en-keyword=Autophagy kn-keyword=Autophagy en-keyword=Resveratrol kn-keyword=Resveratrol en-keyword=Skin fibroblasts kn-keyword=Skin fibroblasts en-keyword=Bioactive compounds kn-keyword=Bioactive compounds END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue=4 article-no= start-page=781 end-page=794 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Does International Environmental Certification Change Local Production and Trade Practices? A Case Study of Shrimp Farming in Southern Vietnam en-subtitle= kn-subtitle= en-abstract= kn-abstract=Studies on international environmental certification (IEC) have primarily focused on how certification can sustainably “upgrade” local production and trading practices. However, not many studies view this market-based governance process from the perspective of local practices and location-specific factors. This study therefore examines how the upstream of the local supply chain influenced global interventions through the case of certification for shrimp farming in the mangroves of southern Vietnam. To clarify various aspects of these interactions, semi-structured interviews were conducted with the provincial government, NGOs, a trading company, shrimp farmers, and middlemen. The results revealed that IEC did not affect local production practices and only partially influenced trade practices. The implementation of IEC was thus at the mercy of the robustness of local society, which was attributed to unique agroecology, production systems, and upstream customary economic practices. en-copyright= kn-copyright= en-aut-name=WatanabeHiroki en-aut-sei=Watanabe en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UbukataFumikazu en-aut-sei=Ubukata en-aut-mei=Fumikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Institute of Academic and Research, Okayama University kn-affil= en-keyword=International environmental certification kn-keyword=International environmental certification en-keyword=Shrimp farming kn-keyword=Shrimp farming en-keyword=Upstream of supply chain kn-keyword=Upstream of supply chain en-keyword=Local robustness kn-keyword=Local robustness en-keyword=Vietnam kn-keyword=Vietnam END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=コダマカワザンショウ属の八重山諸島産新種 (腹足綱: クビキレガイ上科: カワザンショウ科) — 同属で世界最北の現生種 kn-title=A new species of Ovassiminea Thiele, 1927 (Gastropoda: Truncatelloidea: Assimineidae) from the Yaeyama Islands, Okinawa, southern Japan — the northernmost record among recent species of the genus en-subtitle= kn-subtitle= en-abstract=沖縄県八重山諸島の西表島・石垣島から新種 Ovassiminea hayasei n. sp. ウラウチコダマカワザンショウを記載する。Ovassiminea Thiele, 1927 コダマカワザンショウ属は西太平洋の熱帯・亜熱帯に分布し, 本新種は同属中で世界最北の現生種である。本新種の産地は極端に狭い範囲に限られ, 沖縄県と環境省のレッドリストで絶滅危惧II類 (VU) とされている。なお文末の Appendix には, これまでに記載されたコダマカワザンショウ属全種 (現生5・化石5) の目録を, 異名表とともに挙げる。 kn-abstract=Ovassiminea hayasei n. sp. is described from mangrove swamps in Iriomote and Ishigaki Islands, of the Yaeyama Islands at the southwestern part of the Ryūkyū Archipelago, Okinawa, Japan.

Exogenous over-expression of PGC-1α by injection of the mRNA construct into oocytes 20 h after the start of IVM culture significantly increased the copy number of mtDNA in the oocytes, but reduced the incidences of oocytes matured to the metaphase-II stage after the IVM culture for totally 44 h and completely suppressed the early development in vitro to the blastocyst stage following parthenogenetic activation. The exogenous expression of PGC-1α also significantly induced spindle defects and chromosome misalignments. Furthermore, markedly higher ROS levels were observed in the PGC-1α-overexpressed mature oocytes, whereas mRNA level of SOD1, encoded for a ROS scavenging enzyme, was decreased. These results conclude that forced expression of PGC-1α successfully increase mtDNA copy number but led to increased ROS production, evidently by downregulation of SOD1 gene expression, inducement of spindle aberration/chromosomal misalignment, and consequently reduction in the meiotic and developmental competences of porcine oocytes. en-copyright= kn-copyright= en-aut-name=DoSon Quang en-aut-sei=Do en-aut-mei=Son Quang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NguyenHai Thanh en-aut-sei=Nguyen en-aut-mei=Hai Thanh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WakaiTakuya en-aut-sei=Wakai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FunahashiHiroaki en-aut-sei=Funahashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Porcine kn-keyword=Porcine en-keyword=Mitochondria kn-keyword=Mitochondria en-keyword=Oocytes kn-keyword=Oocytes en-keyword=PGC-1 alpha kn-keyword=PGC-1 alpha en-keyword=In vitro maturation kn-keyword=In vitro maturation END start-ver=1.4 cd-journal=joma no-vol=226 cd-vols= no-issue= article-no= start-page=158 end-page=166 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240915 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The impact of cumulus cell viability and pre-culture with the healthy cell mass on brilliant cresyl blue (BCB) staining assessment and meiotic competence of suboptimal porcine oocytes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives of the present study were to investigate the characteristics including glucose-6-phosphate dehydrogenase activity, as determined by Brilliant Cresyl Blue (BCB) staining, of suboptimal porcine oocytes and to enhance the meiotic competence of those through pre-culture with cumulus cell masses (CCMs). Percentage of oocyte-cumulus complexes (OCCs) derived from small follicles (SF; <3 mm in diameter) containing the oocytes that were assessed as BCB-negative (BCB-) was significantly higher than those derived from medium follicles (MF; 3–6 mm in diameter). Degrees of dead cumulus cells were significantly higher in OCCs containing BCB- oocytes, regardless of the origin of OCCs (MF vs. SF), than those containing BCB-positive (BCB+) ones. Exposing OCCs containing BCB+ oocytes to the apoptosis inducer, carbonyl cyanide m-chlorophenylhydrazone, for 20 h significantly induced the transition to BCB- and meiotic progression of exposed OCCs were significantly reduced in both SF and MF derived ones. Transit of BCB- oocytes to BCB+ was induced when OCCs were pre-cultured with CCMs of MF derived OCCs containing BCB+ oocytes for 20 h before IVM. This pre-culture also significantly increased the meiotic competence of BCB- oocytes, particularly in SF derived ones. However, reactive oxygen species levels were significantly higher in BCB+ oocytes as compared with BCB- ones, regardless of pre-culture with CCMs, whereas no significant differences were found in the ATP contents among the treatment groups. In conclusion, the BCB result of oocytes could be regulated by the healthy status and content of surrounding cumulus cells and the meiotic competence of suboptimal BCB- porcine oocytes is improved by pre-culture with healthy CCMs. en-copyright= kn-copyright= en-aut-name=FonsekaWanniarachchige Tharindu Lakshitha en-aut-sei=Fonseka en-aut-mei=Wanniarachchige Tharindu Lakshitha kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DoSon Quang en-aut-sei=Do en-aut-mei=Son Quang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=VanPhong Ngoc en-aut-sei=Van en-aut-mei=Phong Ngoc kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NguyenHai Thanh en-aut-sei=Nguyen en-aut-mei=Hai Thanh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WakaiTakuya en-aut-sei=Wakai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FunahashiHiroaki en-aut-sei=Funahashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Oocytes kn-keyword=Oocytes en-keyword=Meiotic competence kn-keyword=Meiotic competence en-keyword=Brilliant cresyl blue kn-keyword=Brilliant cresyl blue en-keyword=Cumulus cells kn-keyword=Cumulus cells END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue= article-no= start-page=300 end-page=302 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=NAITOH Naoki and MORI Akiko (eds.).

In ancient Japanese local communities, there existed complex webs of historical rule and intertwined relationships between local clans that date back to before the establishment of the Ritsuryō system. Gun-teki sekai is a term that refers to the reality of the control of the provincial and district systems, in which multiple powerful clans served as gunji , district governors under the Ritsuryō system. Each gunji organized smaller clans below them to carry out administrative duties based on such relationships. Recent research is beginning to reveal the multipolar structure of the gun-teki sekai .
　In this study, the author examines the gun-teki sekai through an analysis of the Asuwa district in Echizen province, which is rich in historical materials. As a result, the following four points became clear. First, it is highly likely that the powerful clans who served as district governors in the mid-Nara period were traditional clans with roots in the eastern part of the district. Second, the powerful clans who served as district deputy governors may have been an emerging power. Third, from an archaeological perspective, the eastern part of the district is the traditional area, while the dominance of the western part of the district developed after the establishment of the Ritsuryō system. Fourth, in terms of clan distribution, the clans who served as district governors were distributed over the widest area, followed by those who served as district deputy governors. en-copyright= kn-copyright= en-aut-name=WATANABEAtsunori en-aut-sei=WATANABE en-aut-mei=Atsunori kn-aut-name=渡部敦寛 kn-aut-sei=渡部 kn-aut-mei=敦寛 aut-affil-num=1 ORCID= affil-num=1 en-affil=Chigasaki City Museum kn-affil= en-keyword=Gun-teki sekai kn-keyword=Gun-teki sekai en-keyword=gunji（district governors under the Ritsuryō system) kn-keyword=gunji（district governors under the Ritsuryō system) en-keyword=local powerful clans kn-keyword=local powerful clans en-keyword=clan distribution kn-keyword=clan distribution en-keyword=Asuwa district kn-keyword=Asuwa district en-keyword=Echizen province kn-keyword=Echizen province END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue= article-no= start-page=53 end-page=63 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=What is education for sustainable development?: From the perspective of international legal history kn-title=持続可能な開発のための教育とは―国際法制史の視点から― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Throughout the history of international law, sustainable development has always been acknowledged as a global responsibility. In recent years, as global environmental concerns have escalated, this responsibility has become increasingly crucial. To fulfil this mandate, education policies must transcend national boundaries. Specifically, in light of pressing global environmental issues such as climate change, education on sustainable development is pivotal for the well-being of future generations. To delve deeper into this significance, the author examines the emergence of ESD (Education for Sustainable Development), its accomplishments, and the challenges the world is currently grappling with. en-copyright= kn-copyright= en-aut-name=KAWAKAMIYoko en-aut-sei=KAWAKAMI en-aut-mei=Yoko kn-aut-name=川上陽子 kn-aut-sei=川上 kn-aut-mei=陽子 aut-affil-num=1 ORCID= affil-num=1 en-affil=Ph.D in law, Université Toulouse Capitole kn-affil= en-keyword=ESD kn-keyword=ESD en-keyword=SDGs kn-keyword=SDGs en-keyword=international environmental law kn-keyword=international environmental law en-keyword=international law kn-keyword=international law en-keyword=human rights kn-keyword=human rights END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=cmad074 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230719 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of 2-week postpartum check-ups on screening positive for postpartum depression: a population-based cohort study using instrumental variable estimation in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Postpartum depression is experienced by approximately 10% of women and affects the health and development of their children. Although it is recommended that all mothers have the opportunity for early detection and intervention for postpartum depression, it is unclear whether early postpartum check-ups help to reduce postpartum depression.
Objective: The aim of this study was to assess the effect of 2-week postpartum check-ups on screening positive for postpartum depression in Japan.
Methods: This was a population-based cohort study that used the administrative database of Tsuyama, Japan. Participants were women who received postpartum home visits from a public health nurse in Tsuyama during the fiscal years 2017–2019. Data were obtained on participant’s attendance at a 2-week postpartum check-up and their responses on the Edinburgh Postpartum Depression Scale. Owing to the initiation of a publicly funded postpartum check-up programme, participants were pseudo-randomly assigned to receive/not receive a 2-week postpartum check-up. We conducted instrumental variable estimation to assess the causal effects of the check-up on screening positive for postpartum depression.
Results: The characteristics of the 1,382 participants did not differ by fiscal year of childbirth. We found a 6.7% (95% confidence interval 2.2–11.2) reduction in the prevalence of screening positive for postpartum depression as an effect of 2-week postpartum check-ups among women received 1-month postpartum home visits.
Conclusion: The results suggest that 2-week postpartum check-ups are effective in reducing the prevalence of screening positive for postpartum depression among 1-month postpartum women. Despite some limitations, early postpartum care could reduce postpartum depression. en-copyright= kn-copyright= en-aut-name=NakamuraNaoko en-aut-sei=Nakamura en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakashimaYasuko en-aut-sei=Nakashima en-aut-mei=Yasuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Health Promotion Division, Tsuyama City Department of Children’s Health kn-affil= affil-num=4 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=community health planning kn-keyword=community health planning en-keyword=diagnostic screening programmes kn-keyword=diagnostic screening programmes en-keyword=home visits kn-keyword=home visits en-keyword=postpartum depression kn-keyword=postpartum depression en-keyword=postnatal care kn-keyword=postnatal care en-keyword=quasi-experimental study kn-keyword=quasi-experimental study END start-ver=1.4 cd-journal=joma no-vol=136 cd-vols= no-issue=3 article-no= start-page=107 end-page=111 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Changes in the drug discovery environment and the roles required of academic researchers kn-title=創薬環境の変遷とアカデミア研究者に求められる役割について en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=NakayamaMasanori en-aut-sei=Nakayama en-aut-mei=Masanori kn-aut-name=中山雅敬 kn-aut-sei=中山 kn-aut-mei=雅敬 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Pathophysiology and Drug Discovery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学学術研究院医歯薬学域　病態生理・創薬学 en-keyword=創薬 kn-keyword=創薬 en-keyword=創薬エコシステム kn-keyword=創薬エコシステム en-keyword=スタートアップ kn-keyword=スタートアップ END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241214 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of aged microplastics on paddy soil properties and greenhouse gas emissions under laboratory aerobic conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Microplastics (MPs) formed after changes in chemical or physical properties may alter soil properties, which in turn may affect microbial activities and greenhouse gas (GHG) emissions. However, few studies have focused on the effects of aged MPs changes on soil properties and greenhouse gas emissions. Therefore, we aimed to investigate the impact of MPs with different aging times on soil GHG emissions and dissolved organic carbon (DOC). Low-density polyethylene (PE) and polylactic acid (PLA) were treated with ultraviolet (UV) irradiation for 0–2 weeks. Soil was incubated with PE or PLA 1% (w/w) concentration at 60% water holding capacity (WHC) for 35 days. Emissions of nitrous oxide (N2O) and carbon dioxide (CO2) were measured on days 0, 1, 3, 5, 7, 14, 21, 28, and 35. Results showed that CO2 and N2O emissions were higher (p < 0.05) in MPs-amended treatments than those without MPs and increased with MPs age. The addition of virgin PE did not affect soil DOC content, whereas aged PE and all PLA additions significantly increased soil DOC content on day 0, probably because UV irradiation caused the degradation of MPs to smaller molecules. In addition, aged MPs addition altered DOC spectral characteristics on day 7, possibly because aged PE and PLA promote microbial decomposition of organic matter by altering soil properties. Changes in soil DOC content and specific ultraviolet absorbance (SUVA) by aged PE and PLA probably promoted the emissions of CO2 and N2O compared to virgin MPs or soil only. Our study revealed that aged PE and PLA promote GHG emissions from soil by changing DOC contents and qualities. en-copyright= kn-copyright= en-aut-name=ZhangTian en-aut-sei=Zhang en-aut-mei=Tian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SomuraHiroaki en-aut-sei=Somura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkaoSatoshi en-aut-sei=Akao en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaharaNozomi en-aut-sei=Nakahara en-aut-mei=Nozomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PereraGamamada Liyanage Erandi Priyangika en-aut-sei=Perera en-aut-mei=Gamamada Liyanage Erandi Priyangika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakanoChiyu en-aut-sei=Nakano en-aut-mei=Chiyu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MaedaMorihiro en-aut-sei=Maeda en-aut-mei=Morihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Science and Engineering, Doshisha University kn-affil= affil-num=4 en-affil=Environmental Management Center, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Aged MPs kn-keyword=Aged MPs en-keyword=biodegradable plastics kn-keyword=biodegradable plastics en-keyword=microplastics kn-keyword=microplastics en-keyword=nitrogen transformation kn-keyword=nitrogen transformation en-keyword=organic carbon decomposition kn-keyword=organic carbon decomposition END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=82 end-page=89 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of high blood pressure on the risk of mortality among Japanese people aged 65 years and older en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: The purpose of this study is to investigate the impact of abnormal blood pressure on the risk of all-cause and cardiovascular mortality in a large cohort of older Japanese people aged ≥65 years.
Methods: This cohort study enrolled 54 760 participants from Okayama City aged ≥65 years who underwent basic health checkups from April 2006 to March 2008. Based on blood pressure, the participants were divided into six categories, from C1 (lowest) to C6 (highest). To assess the association of blood pressure with all-cause and cardiovascular mortality, we used survival analysis to estimate hazard ratios (HRs) for all-cause mortality and subdistribution HRs (SHRs) for cardiovascular mortality on C3. We then repeated the analyses based on age groups (65–74 years, 75–84 years, and ≥85 years).
Results: The fully adjusted HRs for all-cause mortality, which included all individual potential confounders, were 1.11 (95% confidence interval [CI]: 1.04–1.19) for C5 and 1.23 (95% CI: 1.09–1.38) for C6, respectively. The fully adjusted SHRs for cardiovascular mortality were 1.11 (95% CI: 1.01–1.21) for C4, 1.19 (95% CI: 1.05–1.34) for C5, and 1.36 (95% CI: 1.09–1.70) for C6. In the age-stratification, an increased risk of hypotension was observed with older age. The HR for C1 was 1.28 (95% CI: 1.16–1.41) for ≥85 years.
Conclusions: Hypertension increased the risk of all-cause and cardiovascular mortality among those aged 65–74 and 75–84 years, but not among those aged ≥85 years.

Under hydrothermal conditions, the refinement of dispersed oil droplets in water (O/W emulsions) and the polymerization reaction could be simultaneously advanced, and polymer particles of polystyrene (PS), polyvinyl alcohol (PVA), polymethyl methacrylate (PMMA), and poly-L-lactic acid (PLLA) with a particle size of about 100 nm could be synthesized. The coating of polymer particles gave an improved effect on the water repellency of WTBs due to the hydrophobicity of polymer particles and an alteration of surface roughness, and it also provided long-term stability (more than 6 years). en-copyright= kn-copyright= en-aut-name=ShimanouchiToshinori en-aut-sei=Shimanouchi en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HirotaDaichi en-aut-sei=Hirota en-aut-mei=Daichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaMasafumi en-aut-sei=Yoshida en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasuharaKazuma en-aut-sei=Yasuhara en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimuraYukitaka en-aut-sei=Kimura en-aut-mei=Yukitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Environmental Chemistry and Materials, Okayama University, kn-affil= affil-num=2 en-affil=Department of Environmental Chemistry and Materials, Okayama University, kn-affil= affil-num=3 en-affil=Department of Environmental Chemistry and Materials, Okayama University, kn-affil= affil-num=4 en-affil=Division of Materials Science, Nara Institute of Science and Technology (NAIST) kn-affil= affil-num=5 en-affil=Department of Environmental Chemistry and Materials, Okayama University, kn-affil= en-keyword=polymer particles kn-keyword=polymer particles en-keyword= emulsification kn-keyword= emulsification en-keyword= water repellency kn-keyword= water repellency en-keyword= hydrophobicity kn-keyword= hydrophobicity en-keyword= coating kn-keyword= coating en-keyword= convective self-assembly kn-keyword= convective self-assembly en-keyword= wood thin board kn-keyword= wood thin board END start-ver=1.4 cd-journal=joma no-vol=306 cd-vols= no-issue= article-no= start-page=109175 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Regional-scale evaluation of tertiary irrigation system in Muda Irrigation Scheme from space en-subtitle= kn-subtitle= en-abstract= kn-abstract=A tertiary irrigation system is essential for efficient water management in large-scale irrigation scheme and requires regular evaluation to understand their effectiveness. The current water balance method for tertiary irrigation system evaluation requires extensive data, making continuous monitoring over vast areas unfeasible. A better approach using geospatial data from the Google Earth Engine (GEE) is introduces to evaluate the efficiency of tertiary irrigation systems on a regional scale, aiding water management strategies. This study aims to (1) define the rice cultivation boundary for accurate data collection and (2) quantitatively evaluate irrigation system performance using specific indicators. Remote sensing evapotranspiration (RS-ET) and yield derived from Normalized Difference Vegetation Index (NDVI) were collected within rice cultivation boundary across 60 irrigation blocks, including 14 blocks equipped with tertiary irrigation system in Region II of the Muda Irrigation Scheme. Three irrigation system performance indicators (equity, adequacy, and water productivity) were used as a key metric in over four rice-growing seasons to evaluate tertiary irrigation system. Results reveal that tertiary irrigation system performance varies with the current three-phase water management strategy. Equity performance was highest during the off-season, particularly in phase 1 (2–8 %). Adequacy was moderate across all phases and seasons (median: 0.6–0.67), while water productivity showed consistent strength in phases 1 and 3, with fluctuations in phase 2, across seasons. This study underscores the cost-effectiveness and efficiency of using geospatial data from space for continuous regional-scale monitoring, highlighting areas for improvement in the current water management strategy. en-copyright= kn-copyright= en-aut-name=ZahirAliya Mhd en-aut-sei=Zahir en-aut-mei=Aliya Mhd kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SomuraHiroaki en-aut-sei=Somura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoroizumiToshitsugu en-aut-sei=Moroizumi en-aut-mei=Toshitsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Water management kn-keyword=Water management en-keyword=Remote sensing kn-keyword=Remote sensing en-keyword=Irrigation performance kn-keyword=Irrigation performance en-keyword=Irrigation system kn-keyword=Irrigation system en-keyword=Earth observation data kn-keyword=Earth observation data en-keyword=Muda Irrigation Scheme kn-keyword=Muda Irrigation Scheme END start-ver=1.4 cd-journal=joma no-vol=184 cd-vols= no-issue=1 article-no= start-page=24 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=In vitro fertilization and long-term child health and development: nationwide birth cohort study in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=The aim of this study is to compare long-term health outcomes between IVF-conceived children and non-IVF-conceived children in Japan, in the context of strong recommendation for single embryo transfer. Using data from a nationwide birth cohort linked with perinatal database, this study analyzed 2140 children born in Japan in May 2010. It compared child health and development outcomes up to 9 years of age between IVF-conceived and non-IVF-conceived children (binary exposure). A Poisson regression with robust variance to estimate the risk ratios for the association between IVF and various long-term child health and developmental outcomes. After adjusting for confounding factors, no significant differences were observed between IVF-conceived and naturally conceived children for most outcomes, including hospitalization, obesity, and developmental milestones. IVF-conceived children showed a slightly lower risk of attention problems at 8 years (adjusted Risk Ratio [aRR]: 0.73, 95% CI: 0.53–1.00). In subgroup analyses, IVF-conceived term children and singletons demonstrated reduced risk of cognitive delays at 5.5 years (aRR: 0.31, 95% CI: 0.10–0.96 and aRR: 0.37, 95% CI: 0.14–0.98, respectively).
Conclusion: In this Japanese cohort, IVF conception was not associated with adverse long-term health or developmental outcomes. These findings provide reassurance about the safety of IVF, particularly in the context of single embryo transfer policies. Further research is needed to explore specific IVF protocols and subgroups. en-copyright= kn-copyright= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei=

Study in Okayama, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: In Japan, approximately 97 million individuals have received their primary two doses of coronavirus disease 2019 (COVID-19) vaccine at the end of 2022. In this study, we aim to examine the effectiveness of the primary vaccines and compare its efficacy to booster vaccine shots in terms of preventing COVID-19 exacerbations during the Omicron-predominant period in Japan.
Methods: For this analysis, we have collected all the confirmed COVID-19-positive cases from different medical institutions in Okayama City and have also utilized the information from the public Vaccination Record System. Taking the number of vaccinations into consideration, we then conducted a population-based study to assess the effectiveness of the two primary vaccine doses in preventing COVID-19 exacerbations during the Omicron waves. Our primary and secondary outcomes were COVID-19 exacerbations with respiratory failure (i.e., oxygen saturation on room air ≤ 93%, requiring supplemental oxygen), intensive care unit admission and/or mechanical ventilator requirement, or death, in accordance with the Japanese COVID-19 guidelines, and pneumonia during the course of COVID-19 infection, respectively.
Results: In total, 95,329 COVID-19-positive individuals, aged 5 years and above, were included in this analysis (study period from January 1 to September 10, 2022). As per our findings, the effectiveness of the primary two doses against COVID-19 exacerbations compared with those who had never been vaccinated was 55.5% (95% confidential interval [CI]: 32.6-71.7), whereas it was higher after the third dose (76.9%; 95% CI: 66.7-84.0) and the fourth dose (75.7%; 95% CI: 58.8-85.7). Effectiveness was sustained for ≥ 5 months after the third vaccination, and preventive effectiveness was observed in individuals aged ≥ 65 years.
Conclusions: As per the results of this study, we can conclude that the efficacy of the primary two doses of SARS-CoV-2 vaccine can be further strengthened in terms of preventing COVID-19 exacerbations by administering third and fourth booster vaccine shots. The additional bivalent vaccine is anticipated to further increase its efficacy against the Omicron strain, suggesting that individuals who have not received their booster shots yet should consider getting them to prevent COVID-19 exacerbations. en-copyright= kn-copyright= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsuoRumi en-aut-sei=Matsuo en-aut-mei=Rumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KadowakiTomoka en-aut-sei=Kadowaki en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=Vaccine kn-keyword=Vaccine en-keyword=Omicron kn-keyword=Omicron en-keyword=Prevention kn-keyword=Prevention en-keyword=Pneumonia kn-keyword=Pneumonia END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=2 article-no= start-page=129 end-page=137 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230414 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Disease and Injury Trends following Heavy Rains in Western Japan in 2018 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Torrential rains occurred in Okayama in western Japan in July 2018, forcing local residents to evacuate. Few studies have reported early-phase disease and injury trends among patients following torrential rains. Thus, in this study, we assessed the illness and injury trends among patients who visited temporary medical facilities located in the areas affected by the 2018 torrential rains; these facilities opened 10 d after the disaster.
Methods: We evaluated the trends among patients who visited a medical clinic located in the area in western Japan affected by heavy rains in 2018. We reviewed medical charts related to 1,301 outpatient visits and conducted descriptive analyses.
Results: More than half of the patients were over 60 years old. The patients experienced mild injuries (7.9% of total visits) as well as common diseases such as hypertensive diseases (30%), diabetes mellitus (7.8%), acute upper respiratory infections (5.4%), skin diseases (5.4%), and eye diseases (4.8%). Hypertensive diseases were the main cause of a visit in any week. Eye problems were the second-highest reason for a visit in the first week, but there was a relative decrease from the first to the third week. Additionally, the proportion of injuries and skin diseases increased from the first to the second week, from 7.9% to 11.1% for injuries, and from 3.9% to 6.7% for skin diseases.
Conclusions: The types of diseases changed on a weekly basis. Older adults needed medical support for longer than other age groups. Prior preparedness such as earlier deployment of such temporary clinics can help mitigate the damage to the victims. en-copyright= kn-copyright= en-aut-name=HashimotoChiaki en-aut-sei=Hashimoto en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MurakamiKazuharu en-aut-sei=Murakami en-aut-mei=Kazuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SuganamiShigeru en-aut-sei=Suganami en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Epidemiology, Graduate School of Medicine, Density and Pharmaceutical Sciences Okayama University kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Density and Pharmaceutical Sciences Okayama University kn-affil= affil-num=3 en-affil=Mabi Memorial Hospital kn-affil= affil-num=4 en-affil=Association of Medical Doctors of Asia kn-affil= en-keyword=Common disease kn-keyword=Common disease en-keyword=communicable disease control kn-keyword=communicable disease control en-keyword=disaster kn-keyword=disaster en-keyword=flood kn-keyword=flood en-keyword=heavy rains kn-keyword=heavy rains en-keyword=Okayama kn-keyword=Okayama END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=3 article-no= start-page=e20220127 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Rapid thawing of frozen bull spermatozoa by transient exposure to 70 °C improves the viability, motility and mitochondrial health en-subtitle= kn-subtitle= en-abstract= kn-abstract=Up to now, the definitive conclusion of the positive effects of rapid transient thawing at higher temperatures for shorter durations has not been obtained yet and is still under discussion due to some contradictory findings and limited assessment of post-thawed parameters. The purpose of the current study was to evaluate the effectiveness of rapid thawing in water at 70 °C by using various post-thawed parameters of frozen bull spermatozoa. Experiment 1, monitoring the change of temperature inside frozen bull straw thawed in water at different temperatures. Experiment 2, evaluation of various post-thawed characteristics of frozen bull spermatozoa thawed in water at different temperatures by using a computer-assisted sperm analysis, flow cytometry and immunocytochemistry. The time it took for the temperature inside the straw to warm up to 15 °C was nearly twice as faster when the straw was thawed in 70 °C water compared with 39 °C. Although there were differences among bulls, viability, motility, and mitochondrial membrane potential of spermatozoa thawed at 70 °C for 8 seconds and stabilized at 39 °C for 52 seconds were significantly higher than those of controls (thawed at 39 °C for 60 seconds) at 0 and 3 h after thawing. Just after thawing, however, there were no differences in acrosome integrity and distribution of phospholipase C zeta1, whereas mitochondrial reactive oxygen species production was significantly lower in spermatozoa thawed at 70 °C. From these results, we conclude that rapid thawing at 70 °C and then stabilization at 39 °C significantly improves viability, motility and mitochondrial health of bull spermatozoa rather than conventional thawing at 39 °C. The beneficial effect of rapid transient thawing could be due to shorter exposure to temperatures outside the physiological range, consequently maintaining mitochondrial health. en-copyright= kn-copyright= en-aut-name=NguyenHai Thanh en-aut-sei=Nguyen en-aut-mei=Hai Thanh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DoSon Quang en-aut-sei=Do en-aut-mei=Son Quang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AthurupanaRukmali en-aut-sei=Athurupana en-aut-mei=Rukmali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WakaiTakuya en-aut-sei=Wakai en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FunahashiHiroaki en-aut-sei=Funahashi en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=bull semen kn-keyword=bull semen en-keyword=cryopreservation process kn-keyword=cryopreservation process en-keyword=phospholipase C zeta1 (PLCZ1) kn-keyword=phospholipase C zeta1 (PLCZ1) en-keyword=temperature of thawing kn-keyword=temperature of thawing END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=10 article-no= start-page=1488 end-page=1500 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241015 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Method for Inter-Broadcaster Data Integration of Non-Identifiable Television Viewing Log kn-title=非特定テレビ視聴履歴データの放送局間統合手法 en-subtitle= kn-subtitle= en-abstract=Recently, TV broadcasters have been collecting and utilizing non-personal TV viewing log data, including start and end times of viewing, from TVs connected to the Internet in a format that does not identify individual viewers. However, since each broadcaster can only use its own non-personal TV viewing log data, it has not yet been able to obtain useful knowledge despite the vast amount of data it has accumulated. In addition, the collection methods and data granularity of non-personal TV viewing log data vary from station to station, and the data accumulated by each station cannot be integrated and used. In this paper, we propose a method for matching non-specific viewing history data collected by each broadcaster using its own method, and design and implement a simulator to evaluate the proposed method. The proposed method estimates that TVs whose channel transition timing matches five items collected at the time of viewing history data collection (IP address, zip code, manufacturer ID, browser major version, and browser minor version) are the same TVs. In addition, we designed a simulator that reproduces viewer behavior and applied this method to the viewing history data synthesized from the simulator. As a result, we succeeded in matching approximately 2.41 million TVs out of the 2.5 million units of data generated, showing an identification rate of 96.5%. kn-abstract=近年，各テレビ放送局において，個人を特定しない形式で，インターネット接続されたテレビから視聴開始時刻や視聴終了時刻等を含む非特定視聴履歴データを収集し，利活用する取り組みが進められている．しかし，各放送局は自局の非特定視聴履歴データしか利用できないため，膨大なデータを蓄積しているにもかかわらず，有用な知見を得るまでに至っていないのが現状である．さらに，非特定視聴履歴データの収集方式やデータ粒度は，各局各様となっており，各局が蓄積したデータを統合し，利用することもできていない．そこで本論文では，各局が独自の方式で取得している非特定視聴履歴データを放送局間で統合する手法を提案し，評価するためのシミュレータ設計と実装を行い，提案手法の評価を行う．
提案手法では，各局の視聴履歴データのうち，共通しているIPアドレス・郵便番号・メーカID・ブラウザメジャーバージョン・ブラウザマイナーバージョンの5項目でテレビ受像機を分離処理する．そして，分離された中でこれらの5項目が一致するテレビのうち，さらにチャンネル遷移時刻が一致するテレビを同一テレビと推定する．また，視聴者行動を再現するシミュレータを設計し，そのシミュレータから合成された視聴履歴データに対して，本手法を適用した結果，生成された250万台分のデータのうち約241万台のテレビIDのマッチングに成功し，再現率96.5%であることを示した． en-copyright= kn-copyright= en-aut-name=MatsudaHiroki en-aut-sei=Matsuda en-aut-mei=Hiroki kn-aut-name=松田裕貴 kn-aut-sei=松田 kn-aut-mei=裕貴 aut-affil-num=1 ORCID= en-aut-name=SakakibaraTaichi en-aut-sei=Sakakibara en-aut-mei=Taichi kn-aut-name=榊原太一 kn-aut-sei=榊原 kn-aut-mei=太一 aut-affil-num=2 ORCID= en-aut-name=MayumiDaiki en-aut-sei=Mayumi en-aut-mei=Daiki kn-aut-name=真弓大輝 kn-aut-sei=真弓 kn-aut-mei=大輝 aut-affil-num=3 ORCID= en-aut-name=MatsudaYuki en-aut-sei=Matsuda en-aut-mei=Yuki kn-aut-name=松田裕貴 kn-aut-sei=松田 kn-aut-mei=裕貴 aut-affil-num=4 ORCID= en-aut-name=MizumotoTeruhiro en-aut-sei=Mizumoto en-aut-mei=Teruhiro kn-aut-name=水本旭洋 kn-aut-sei=水本 kn-aut-mei=旭洋 aut-affil-num=5 ORCID= en-aut-name=YasumotoKeiichi en-aut-sei=Yasumoto en-aut-mei=Keiichi kn-aut-name=安本慶一 kn-aut-sei=安本 kn-aut-mei=慶一 aut-affil-num=6 ORCID= affil-num=1 en-affil=Nara Institute of Science and Technology kn-affil=奈良先端科学技術大学院大学 affil-num=2 en-affil=Yomiuri Telecasting Corporation kn-affil=讀賣テレビ放送株式会社 affil-num=3 en-affil=Nara Institute of Science and Technology kn-affil=奈良先端科学技術大学院大学 affil-num=4 en-affil=Okayama University kn-affil=岡山大学 affil-num=5 en-affil=Chiba Institute of Technology kn-affil=千葉工業大学 affil-num=6 en-affil=Nara Institute of Science and Technology kn-affil=奈良先端科学技術大学院大学 en-keyword=テレビ (TV) kn-keyword=テレビ (TV) en-keyword=視聴履歴データ (TV viewing log data) kn-keyword=視聴履歴データ (TV viewing log data) en-keyword=ビッグデータ (Big data) kn-keyword=ビッグデータ (Big data) en-keyword=IoT kn-keyword=IoT en-keyword=クロスデバイスマッチング (Cross-device matching) kn-keyword=クロスデバイスマッチング (Cross-device matching) en-keyword=クロスデバイストラッキング (Cross-device tracking) kn-keyword=クロスデバイストラッキング (Cross-device tracking) END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=24716 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241021 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A nationwide longitudinal survey of infantile injury and its recurrence in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Injury recurrence in young children is a significant public health concern, as it may indicate an unfavorable home environment. This study evaluates whether infantile injuries increase recurrence during preschool years, contributing to more effective prevention strategies for vulnerable families. The study included 20,191 children from "The Longitudinal Survey of Babies in the 21st Century," a representative sample of infants born in Japan between May 10 and 24, 2010. We conducted a logistic regression analysis to compare injury recurrence risk between children aged 18 months to seven years with and without infantile injury histories. The study revealed that infants with a history of injuries had a higher risk of subsequent hospital visits for injuries during preschool years (crude Odds Ratio (cOR) 1.52, 95% CI, 1.41-1.64, adjusted OR (aOR) 1.48, 95% CI 1.37-1.60). Specific injuries, such as falls (aOR 1.34, 95% CI, 1.26-1.43), pinches (aOR 1.22, 95% CI, 1.15-1.29), drowning (aOR 1.29, 95% CI, 1.19-1.40), ingestion (aOR 1.35, 95% CI, 1.17-1.55), and burns (aOR 1.47, 95% CI, 1.31-1.65), independently increased the risk of future injuries. Our findings highlight the necessity of universal safety measures in the home environment and targeted interventions for families with a history of high-risk injuries. en-copyright= kn-copyright= en-aut-name=HiraokaTomohiro en-aut-sei=Hiraoka en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ObaraTakafumi en-aut-sei=Obara en-aut-mei=Takafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NojimaTsuyoshi en-aut-sei=Nojima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HisamuraMasaki en-aut-sei=Hisamura en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Faculty of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Retrospective cohort study kn-keyword=Retrospective cohort study en-keyword=Injury recurrence kn-keyword=Injury recurrence en-keyword=Injury prevention kn-keyword=Injury prevention END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue=2 article-no= start-page=41 end-page=71 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Reproducing Self-organizing Agglomeration using Agent-based Model: ICT Establishments in Tokyo’s Special Wards kn-title=エージェントベースモデルによる自己組織化的集積の再現：特別区におけるICT 事業所 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　As a preliminary step to conducting a self-organizing simulation of the agglomeration and dispersion of the information and communications industry, we quantify the spatial agglomeration of the information and communications industry in Japan’s major cities. Using the town and district data from the Economic Census for Economic Activity, we attempted a spatial analysis of the information and communications industry in the Tokyo Special Wards as well as in Sapporo, Sendai, Hiroshima, and Fukuoka, which have regional central functions. As a result of detecting spatial autocorrelation in small areas within each city, hotspots indicating the agglomeration of information and communications industry offi ces were found in the city center of each city. At the same time, we were able to confi rm the impact of agglomeration economies, which are the premise of the self-organizing model, and confi rmed that the information and communications industry is an industry suitable for simulation of the self-organizing model. 　Krugman（1996）was the fi rst to model the self-organizing model in cities and clarifi ed the emergence principle of peripheral cities, but this was limited to numerical simulations. Later, Kumar et al.（2007）used actual data to show that Krugman’s self-organizing model could be applied to predict corporate agglomeration and dispersion. In this paper, we use an agent-based model to examine whether a self-organizing model is also effective in reproducing and predicting the concentration and dispersion of the information and communications industry in Japanese cities. en-copyright= kn-copyright= en-aut-name=NakamuraRyohei en-aut-sei=Nakamura en-aut-mei=Ryohei kn-aut-name=中村良平 kn-aut-sei=中村 kn-aut-mei=良平 aut-affil-num=1 ORCID= en-aut-name=NagamuneTakeshi en-aut-sei=Nagamune en-aut-mei=Takeshi kn-aut-name=長宗武司 kn-aut-sei=長宗 kn-aut-mei=武司 aut-affil-num=2 ORCID= en-aut-name=HayashiSyusei en-aut-sei=Hayashi en-aut-mei=Syusei kn-aut-name=林秀星 kn-aut-sei=林 kn-aut-mei=秀星 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=新見公立大学 affil-num=3 en-affil= kn-affil=東北大学大学院 END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue=2 article-no= start-page=17 end-page=40 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Achievements and Challenges of Student-led Regional Revitalization Activities over 10 Years: Practical Activities in the Mokake District of Setouchi City kn-title=学生による地方創生活動10年の成果と課題―瀬戸内市裳掛地区での実践活動― en-subtitle= kn-subtitle= en-abstract=　Among the officially recognized student clubs at Okayama University, there is a club called the“ Town Development Research Association” that engages in regional revitalization activities. The Okayama University student club “Town Development Research Association” started its activities in 2014. The purpose of these activities is to collaborate with the local residents in the Mokake district of Oku Town, Setouchi City, which faces issues of depopulation and declining population. This project is commonly known as the “Setouchi City Mokake District Revitalization Project.” 　Over the past ten years, students have carried out various activities while passing down practical activities from seniors to juniors. The main focus of these activities is to support the children of Mokake Elementary School, where the number of students is decreasing, in order to curb the decline in student numbers. Specific measures for this include “information dissemination by students,” “participation in countermeasures for abandoned farmland,” “creating bases through support for the regeneration of vacant houses,” “support for promoting migration and settlement,” “planning and managing local events,” and “watching over the children.” These activities aim to continuously support and revitalize the community. 　This paper reports on the achievements of these student activities, presenting them as a case study of “student-led regional revitalization activities” from the perspective of mutual benefits in terms of student learning and contributions to the community. kn-abstract=　岡山大学の公認学生サークルのなかで地方創生活動を展開しているサークルに「まちづくり研究会」がある。岡山大学学生サークル「まちづくり研究会」は，2014年に活動を開始，その活動の目的は，過疎化人口減少の問題を抱える瀬戸内市邑久町虫明（おくちょうむしあけ）の裳掛（もかけ）地区をフィールドとした学生と地域住民による地方創生の協働活動であり，通称『瀬戸内市裳掛地区再生プロジェクト』と呼ばれている。 　この10年間，学生たちは先輩たちから後輩たちに実践活動をリレーしながら様々な活動を展開してきた。その主眼が，生徒数の減る裳掛小学校の子どもたちの支援活動を続けることで，生徒数の減少に歯止めをかけることである。そのための具体的な方策として，「学生による情報発信」，「耕作放棄地対策への参加」，「空き家の再生支援による拠点づくり」，「移住定住促進支援」，「地域催事への企画・運営支援」，「子どもたちの見守り」などの活動を実践しながら地域を元気にする応援を継続してきた。なお，掲載写真の使用許可は，活動の都度，地域の皆様（保護者を含む）や学生たちに確認・了解を得ている。 　本論では，この学生たちの活動の成果を紹介しながら，学生たちの学びと地域への貢献という互恵性の視座に立ち「学生による地域創生活動の実践事例研究」として報告する。 en-copyright= kn-copyright= en-aut-name=MimuraSatoshi en-aut-sei=Mimura en-aut-mei=Satoshi kn-aut-name=三村聡 kn-aut-sei=三村 kn-aut-mei=聡 aut-affil-num=1 ORCID= en-aut-name=TokooAkane en-aut-sei=Tokoo en-aut-mei=Akane kn-aut-name=床尾あかね kn-aut-sei=床尾 kn-aut-mei=あかね aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学地域共創本部 affil-num=2 en-affil= kn-affil=岡山大学地域共創本部 en-keyword=少子化対策 (Countermeasures against declining birthrates) kn-keyword=少子化対策 (Countermeasures against declining birthrates) en-keyword=空き家の再生 (Revitalization of vacant houses) kn-keyword=空き家の再生 (Revitalization of vacant houses) en-keyword=移住・定住促進 (Promotion of migration and settlement) kn-keyword=移住・定住促進 (Promotion of migration and settlement) END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue=2 article-no= start-page=1 end-page=16 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241125 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Why Is Intermediate Organization Necessary? kn-title=なぜ中間組織が必要なのか en-subtitle= kn-subtitle= en-abstract= kn-abstract=　This paper challenges a fundamental question, ‘Why is an intermediate organization necessary?’ Due to transaction costs and market failures on the one hand and the limitations of organizational control mechanisms on the other hand, many‘ intermediate organizations’ are observed in the real world.

The theoretical elaboration since Ouchi’s（1980） discussion of clan-type governance and cumulative empirical research on industrial agglomerations have allowed us to construct a more sophisticated theory called community capital. 　In effective communities, members are ‘embedded as insiders’ who serve the purpose of the community, share experiences of failures and successes, and find and deepen their common identity. This limited membership is bound by‘ mutual trust to rely on each other’ for‘ distribution of short-term risks.’ In contrast to social norms that need to be abstract enough to be widely shared, the communal norms that are concrete enough to allow the members to understand without hesitation how they should behave in localized contexts are cumulatively cultivated along socializing process. Among the norms, sense of mutual obligation to incur intermittent costs for the whole community is a crucial norm for the sustainable development of the community. However, as a practical matter, membership control, mutual trust and short-term risk allocation may serve the communities in the short run, but they do not guarantee long-term accumulation of shared capital. As a result, the limits of community capital may need to be discussed once again, especially today when market liquidity is increasing, and its failures tend to become more apparent in a variety of areas. en-copyright= kn-copyright= en-aut-name=FujiiDaiji en-aut-sei=Fujii en-aut-mei=Daiji kn-aut-name=藤井大児 kn-aut-sei=藤井 kn-aut-mei=大児 aut-affil-num=1 ORCID= en-aut-name=OshimaTamako en-aut-sei=Oshima en-aut-mei=Tamako kn-aut-name=大島珠子 kn-aut-sei=大島 kn-aut-mei=珠子 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院ヘルスシステム統合科学学域 affil-num=2 en-affil= kn-affil=国際医療福祉大学小田原保健医療学部看護学科 en-keyword=中間組織 kn-keyword=中間組織 en-keyword=内部組織の経済学 kn-keyword=内部組織の経済学 en-keyword=産業集積 kn-keyword=産業集積 en-keyword=コミュニティ・キャピタル kn-keyword=コミュニティ・キャピタル END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=3 article-no= start-page=77 end-page=83 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=2021 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation of drought features in the Dakbla watershed, Central Highlands of Vietnam en-subtitle= kn-subtitle= en-abstract= kn-abstract=The drought impacts in the Dakbla watershed were assessed based on a combination of hydrological modeling and drought indices. Three drought indices, the Standardized Precipitation Index (SPI), Standardized Soil Moisture Index (SSI), and Streamflow Drought Index (SDI) were utilized to evaluate the drought features of meteo-hydrology and agriculture. The results indicated that these indices are well adapted to the local conditions, especially the 12-month time scale. Evaluations of drought features on the watershed scale could provide more specific information regarding drought risk than regional-scale/district-level assessments, because a watershed is a hydrologically fundamental unit to consider water resources management. Additionally, evaluations of drought impacts using the SSI showed longer and higher trends than those using the SPI and SDI in terms of drought duration and frequency. Considering the spatial distribution of drought frequency, the areas predominated by agricultural land in the target watershed had higher drought risk. Thus, assessment of agricultural droughts along with meteo-hydrological droughts is extremely important to support realistic local drought management strategies by considering water availability, water balance, and soil characteristics, especially in specific agricultural areas. en-copyright= kn-copyright= en-aut-name=Ngoc Quynh TramVo en-aut-sei=Ngoc Quynh Tram en-aut-mei=Vo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SomuraHiroaki en-aut-sei=Somura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoroizumiToshitsugu en-aut-sei=Moroizumi en-aut-mei=Toshitsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=hydrological modeling kn-keyword=hydrological modeling en-keyword=drought indices kn-keyword=drought indices en-keyword=drought features kn-keyword=drought features en-keyword=watershed scale assessment kn-keyword=watershed scale assessment en-keyword=agricultural activities kn-keyword=agricultural activities en-keyword=mountainous region kn-keyword=mountainous region END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=4 article-no= start-page=87 end-page=94 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluation and selection of a set of CMIP6 GCMs for water resource modeling in the poorly gauged complex terrain of the Tana River basin in Kenya en-subtitle= kn-subtitle= en-abstract= kn-abstract=The Tana River basin is among the least monitored in terms of meteorological data in Kenya. The Kenya Meteorological Department (KMD) provided data on a ten-day timescale, which is not adequate for water resource evaluation. To bridge this data gap, there is a growing need to leverage General Circulation Models (GCMs) and global datasets to assess current and future water resources in this basin. This study focused on evaluating the performance of 19 CMIP6 GCMs concerning precipitation (pr), maximum temperature (tasmax), and minimum temperature (tasmin) for the complex terrain of the Tana River basin. This involved a rigorous process of disaggregating the data provided by the KMD into a daily timescale for downscaling. The GCMs’ historical output was prepared using the Climate Data Operator (CDO) in Cygwin. The Kling Gupta Efficiency (KGE) was computed for each variable at three stations: Nyeri (upstream), Kitui (midstream), and Bura (downstream). The KGE results were validated using Taylor statistics. Five GCMs, CMCC-ESM2, MPI-ESM1-2-HR, ACCESS-CM2, NorESM2-MM, and GFDL-ESM4, performed best with a multivariable Multi-station KGE statistic of 0.455–0.511. The outputs from these selected GCMs were subsequently downscaled for later use in assessing the water resources and crop water demand in the basin. en-copyright= kn-copyright= en-aut-name=Mwendwa WambuaDaniel en-aut-sei=Mwendwa Wambua en-aut-mei=Daniel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SomuraHiroaki en-aut-sei=Somura en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoroizumiToshitsugu en-aut-sei=Moroizumi en-aut-mei=Toshitsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=climate change kn-keyword=climate change en-keyword=adaptation kn-keyword=adaptation en-keyword=scenarios kn-keyword=scenarios en-keyword=downscaling kn-keyword=downscaling en-keyword=disaggregation kn-keyword=disaggregation en-keyword=temporal kn-keyword=temporal END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=363 end-page=370 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Small-for-Gestational-Age Status and the Risk of Kawasaki Disease: A Nationwide Birth Cohort in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Kawasaki disease (KD) is a pediatric disease of unknown etiology that commonly affects infants in East Asia. Infants born small for gestational age (SGA) have weaker immune systems and are more susceptible to infection. Using data from a nationwide Japanese birth cohort study conducted in 2010 (n=34,579), we investigated whether SGA increases the risk of KD. SGA was defined as birth weight below the 10th percentile for gestational age. The outcome was hospitalization for KD between 6 and 30 months of age. The association between SGA and hospitalization for KD, adjusted for child and maternal factors, was examined using logistic regression. Of the 231 children hospitalized for KD, 9.5% were SGA. Further statistical analysis showed that SGA did not increase the odds ratio (OR) of hospitalization for KD (adjusted OR 1.12, 95% confidence interval 0.71-1.75). This result was not changed with stratification by early daycare attendance and preterm status. Reasons for the lack of association may include the multifactorial pathogenesis of KD; in addition, the types of infections to which SGA infants are predisposed may differ from those triggering KD. Overall, our large nationwide study found no association between SGA and KD. en-copyright= kn-copyright= en-aut-name=TakanagaSatoe en-aut-sei=Takanaga en-aut-mei=Satoe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KadowakiTomoka en-aut-sei=Kadowaki en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Kawasaki disease (KD) kn-keyword=Kawasaki disease (KD) en-keyword=small for gestational age (SGA) kn-keyword=small for gestational age (SGA) en-keyword=cohort kn-keyword=cohort en-keyword=epidemiology kn-keyword=epidemiology END start-ver=1.4 cd-journal=joma no-vol=46 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241031 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学環境管理センター報　第46号 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境管理センター kn-aut-sei=岡山大学環境管理センター kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=9 article-no= start-page=1781 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240828 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Novel C-Terminal Truncated Bacteriocin Found by Comparison between Leuconostoc mesenteroides 406 and 213M0 Isolated from Mongolian Traditional Fermented Milk, Airag en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bacteriocins produced by lactic acid bacteria are known to be useful tools for food biopreservation and fermentation control. Leuconostoc mesenteroides subsp. mesenteroides 406 and 213M0 isolated from different samples of Mongolian traditional fermented milk, airag, had been reported to produce listericidal bacteriocin-like inhibitory substances with similar but slightly different properties. In this study, the antibacterial properties and the related gene sequences of both strains were compared, and then their bacteriocins were purified and identified. Strain 406 was superior to strain 213M0 in cell growth and antibacterial activity against many strains. However, the activity of 213M0 was stronger than that of 406 against a few strains. DNA sequencing revealed two and three plasmids in 406 and 213M0, respectively, and each one of them harbored an almost identical mesentericin Y105-B105 gene cluster. Removal of these plasmids resulted in a complete loss of activity, indicating that the antibacterial activity of both strains was generated by bacteriocins encoded on the plasmids. Mesentericins Y105 and B105 were purified from both cultures, and another novel bacteriocin, named mesentericin M, was identified from the 213M0 culture only. Its structural gene was coded on a 213M0 plasmid and, surprisingly, its C-terminal three amino acid residues were post-translationally cleaved. To our knowledge, this is the first report of a C-terminal truncated bacteriocin. In conclusion, the novel bacteriocin should be mainly responsible for the difference in antibacterial properties between the two strains. en-copyright= kn-copyright= en-aut-name=HasiqimugeChihiro en-aut-sei=Hasiqimuge en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HanoChihiro en-aut-sei=Hano en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ArakawaKensuke en-aut-sei=Arakawa en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaSaki en-aut-sei=Yoshida en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZhaoJunliang en-aut-sei=Zhao en-aut-mei=Junliang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TohHidehiro en-aut-sei=Toh en-aut-mei=Hidehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MoritaHidetoshi en-aut-sei=Morita en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyamotoTaku en-aut-sei=Miyamoto en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Advanced Genomics Center, National Institute of Genetics kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Leuconostoc mesenteroides kn-keyword=Leuconostoc mesenteroides en-keyword=antimicrobial peptide kn-keyword=antimicrobial peptide en-keyword=bacteriocin kn-keyword=bacteriocin en-keyword=Listeria monocytogenes kn-keyword=Listeria monocytogenes en-keyword=fermented milk kn-keyword=fermented milk en-keyword=biopreservation kn-keyword=biopreservation en-keyword=fermentation control kn-keyword=fermentation control en-keyword=post-translational modification kn-keyword=post-translational modification en-keyword=C-terminal cleavage kn-keyword=C-terminal cleavage END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=10 article-no= start-page=239 end-page=244 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=2024101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Reverse Shape Memory Effect and Toughness Recovery of Ti-10V-2Fe-3Al Alloy kn-title=Ti-10V-2Fe-3Al合金の逆形状記憶効果と靭性回復 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ti-10V-2Fe-3Al alloys exhibit shape memory (SM) and reverse shape memory (RSM) effects. When an alloy sample that has been strained by external force at room temperature is heated, the strain recovers and SM effect develops at around 300℃, but as the temperature increases further, the shape changes in the opposite direction due to RSM effect at around 450℃. This RSM effect has potential applications in forming processes such as thin-walled pipes, but has the disadvantage that the RSM treatment makes the material very brittle. Therefore, in this study, a heat treatment to restore toughness while maintaining the shape after forming was investigated. The alloy quenched from 1050℃ had a microstructure consisting of a β matrix phase and α′′-martensite (α′′Mq). Differential scanning calorimetry (DSC) results showed that the continuous heating process occurred in the following order: α′′Mq → β reverse transformation, ω formation, ω disappearance, thermally induced α′′iso phase formation, α precipitation and α → β transformation. Ageing at 300℃, where the SM effect appears, caused significant embrittlement due to the formation of the ageing ω phase. Ageing treatment at 450℃, where the RSM effect is obtained, resulted in the formation of a fine α phase, which also caused significant embrittlement. On the other hand, additional aging at 600℃ for 1.8 ks after RSM treatment significantly improved the toughness and produced material properties comparable to aerospace material specifications. It was found that the embrittlement in the RSM treatment was due to the precipitation of fine α phase, and that the growth of α phase with a width of about 0.2 µm or more was required for toughness recovery. It was also found that the specimen shape formed by the RSM treatment hardly changed after the additional heat treatment of 1.8 ks at 600℃. en-copyright= kn-copyright= en-aut-name=TakemotoYoshito en-aut-sei=Takemoto en-aut-mei=Yoshito kn-aut-name=竹元嘉利 kn-aut-sei=竹元 kn-aut-mei=嘉利 aut-affil-num=1 ORCID= en-aut-name=ShinomiyaDaiki en-aut-sei=Shinomiya en-aut-mei=Daiki kn-aut-name=四宮大輝 kn-aut-sei=四宮 kn-aut-mei=大輝 aut-affil-num=2 ORCID= en-aut-name=IshiharaTaiki en-aut-sei=Ishihara en-aut-mei=Taiki kn-aut-name=石原大暉 kn-aut-sei=石原 kn-aut-mei=大暉 aut-affil-num=3 ORCID= en-aut-name=YokotaHiroto en-aut-sei=Yokota en-aut-mei=Hiroto kn-aut-name=横田啓人 kn-aut-sei=横田 kn-aut-mei=啓人 aut-affil-num=4 ORCID= en-aut-name=ArakawaJinta en-aut-sei=Arakawa en-aut-mei=Jinta kn-aut-name=荒川仁太 kn-aut-sei=荒川 kn-aut-mei=仁太 aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学環境生命自然科学学域 affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学大学院環境生命自然科学研究科 affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学大学院環境生命自然科学研究科 affil-num=5 en-affil=Faculty of Environmental, Life, Natural Science and Technology, Okayama University kn-affil=岡山大学環境生命自然科学学域 en-keyword=reverse shape memory kn-keyword=reverse shape memory en-keyword=α′′-phase kn-keyword=α′′-phase en-keyword=deformation induced martensite kn-keyword=deformation induced martensite en-keyword=β-type titanium alloy kn-keyword=β-type titanium alloy en-keyword=brittle fracture kn-keyword=brittle fracture en-keyword=toughness kn-keyword=toughness en-keyword=shape recovery kn-keyword=shape recovery en-keyword=ω-phase kn-keyword=ω-phase en-keyword=variant kn-keyword=variant END start-ver=1.4 cd-journal=joma no-vol=65 cd-vols= no-issue=11 article-no= start-page=1769 end-page=1786 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240824 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Nutrient Requirements Shape the Preferential Habitat of Allorhizobium vitis VAR03-1, a Commensal Bacterium, in the Rhizosphere of Arabidopsis thaliana en-subtitle= kn-subtitle= en-abstract= kn-abstract=A diverse range of commensal bacteria inhabit the rhizosphere, influencing host plant growth and responses to biotic and abiotic stresses. While root-released nutrients can define soil microbial habitats, the bacterial factors involved in plant–microbe interactions are not well characterized. In this study, we investigated the colonization patterns of two plant disease biocontrol agents, Allorhizobium vitis VAR03-1 and Pseudomonas protegens Cab57, in the rhizosphere of Arabidopsis thaliana using Murashige and Skoog (MS) agar medium. VAR03-1 formed colonies even at a distance from the roots, preferentially in the upper part, while Cab57 colonized only the root surface. The addition of sucrose to the agar medium resulted in excessive proliferation of VAR03-1, similar to its pattern without sucrose, whereas Cab57 formed colonies only near the root surface. Overgrowth of both bacterial strains upon nutrient supplementation inhibited host growth, independent of plant immune responses. This inhibition was reduced in the VAR03-1 ΔrecA mutant, which exhibited increased biofilm formation, suggesting that some activities associated with the free-living lifestyle rather than the sessile lifestyle may be detrimental to host growth. VAR03-1 grew in liquid MS medium with sucrose alone, while Cab57 required both sucrose and organic acids. Supplementation of sugars and organic acids allowed both bacterial strains to grow near and away from Arabidopsis roots in MS agar. These results suggest that nutrient requirements for bacterial growth may determine their growth habitats in the rhizosphere, with nutrients released in root exudates potentially acting as a limiting factor in harnessing microbiota. en-copyright= kn-copyright= en-aut-name=HemeldaNiarsi Merry en-aut-sei=Hemelda en-aut-mei=Niarsi Merry kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BaoJiyuan en-aut-sei=Bao en-aut-mei=Jiyuan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeMegumi en-aut-sei=Watanabe en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuiHidenori en-aut-sei=Matsui en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ToyodaKazuhiro en-aut-sei=Toyoda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IchinoseYuki en-aut-sei=Ichinose en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NoutoshiYoshiteru en-aut-sei=Noutoshi en-aut-mei=Yoshiteru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Commensal bacteria kn-keyword=Commensal bacteria en-keyword=Nutrient requirements kn-keyword=Nutrient requirements en-keyword=Organic acids kn-keyword=Organic acids en-keyword=Plant-microbe interactions kn-keyword=Plant-microbe interactions en-keyword=Rhizosphere kn-keyword=Rhizosphere en-keyword=Sugars kn-keyword=Sugars END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=17 article-no= start-page=2824 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240823 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cyclic Oligosaccharide-Induced Modulation of Immunoglobulin A Reactivity to Gut Bacteria Contributes to Alterations in the Bacterial Community Structure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immunoglobulin A (IgA) is a major gut antibody that coats commensal gut bacteria and contributes to shaping a stable gut bacterial composition. Although previous studies have shown that cyclic oligosaccharides, including cyclic nigerosyl-1,6-nigerose (CNN) and cyclodextrins (CDs, including alpha CD, beta CD, and gamma CD), alter the gut bacterial composition, it remains unclear whether cyclic oligosaccharides modify the IgA coating of gut bacteria, which relates to cyclic oligosaccharide-induced alteration of the gut bacterial composition. To address this issue, mice were maintained for 12 weeks on diets containing CNN, alpha CD, beta CD, or gamma CD; the animals' feces were evaluated for their bacterial composition and the IgA coating index (ICI), a measure of the degree of IgA coating of bacteria. We observed that the intake of each cyclic oligosaccharide altered the gut bacterial composition, with changes in the ICI found at both the phylum and genus levels. The ICI for Bacillota, Lachnospiraceae NK4A136 group, UC Lachnospiraceae, and Tuzzerella were significantly and positively correlated with the relative abundance (RA) in total bacteria for these bacteria; in contrast, significant correlations were not seen for other phyla and genera.

Illumina sequencing of A. crassicarpa was conducted, and the raw data of 124,410,892 reads were filtered and assembled de novo into 93,317 unigenes, with a total of 84,411,793 bases. Blast2GO annotation, Benchmark Universal Single-Copy Ortholog evaluation, and GO-term classification produced a catalogue of unigenes for studying primary metabolism, phytohormone signaling, and transcription factors. Massive transcriptomic analysis has identified microsatellites composed of simple sequence repeat (SSR) loci representing di-, tri-, and tetranucleotide repeat units in the predicted open reading frames. Polymorphism was induced by PCR amplification of microsatellite loci located in several genes encoding auxin response factors and other transcription factors, which successfully distinguished 16 local trees of A. crassicarpa tested, representing potentially exploitable molecular markers for efficient tree breeding for plantation and biomass exploitation. en-copyright= kn-copyright= en-aut-name=IshioShougo en-aut-sei=Ishio en-aut-mei=Shougo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KusunokiKazutaka en-aut-sei=Kusunoki en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NemotoMichiko en-aut-sei=Nemoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanaoTadayoshi en-aut-sei=Kanao en-aut-mei=Tadayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TamuraTakashi en-aut-sei=Tamura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Tsukuba Research Institute, Sumitomo Forestry Co.

In this study, we evaluated the modulating effect of quercetin on the cytotoxicity induced by acetaldehyde in mouse hepatoma Hepa1c1c7 cells, the frequently used cellular hepatocyte model. The pretreatment with quercetin significantly inhibited the cytotoxicity induced by acetaldehyde. The treatment with quercetin itself had an ability to enhance the total ALDH activity, as well as the ALDH1A1 and ALDH3A1 gene expressions. The acetaldehyde treatment significantly enhanced the intracellular reactive oxygen species (ROS) level, whereas the quercetin pretreatment dose-dependently inhibited it. Accordingly, the treatment with quercetin itself significantly up-regulated the representative intracellular antioxidant-related gene expressions, including heme oxygenase-1 (HO-1), glutamate-cysteine ligase, catalytic subunit (GCLC), and cystine/glutamate exchanger (xCT), that coincided with the enhancement of the total intracellular glutathione (GSH) level. Tin protoporphyrin IX (SNPP), a typical HO-1 inhibitor, restored the quercetin-induced reduction in the intracellular ROS level, whereas buthionine sulphoximine, a representative GSH biosynthesis inhibitor, did not. SNPP also cancelled the quercetin-induced cytoprotection against acetaldehyde. These results suggest that the low-molecular-weight antioxidants produced by the HO-1 enzymatic reaction are mainly attributable to quercetin-induced cytoprotection. en-copyright= kn-copyright= en-aut-name=LiKexin en-aut-sei=Li en-aut-mei=Kexin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KidawaraMinori en-aut-sei=Kidawara en-aut-mei=Minori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChenQiguang en-aut-sei=Chen en-aut-mei=Qiguang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MunemasaShintaro en-aut-sei=Munemasa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurataYoshiyuki en-aut-sei=Murata en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraToshiyuki en-aut-sei=Nakamura en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakamuraYoshimasa en-aut-sei=Nakamura en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=quercetin kn-keyword=quercetin en-keyword=acetaldehyde kn-keyword=acetaldehyde en-keyword=glutathione kn-keyword=glutathione en-keyword=aldehyde dehydrogenase kn-keyword=aldehyde dehydrogenase en-keyword=heme oxygenase-1 kn-keyword=heme oxygenase-1 END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=1403922 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240820 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Lentil adaptation to drought stress: response, tolerance, and breeding approaches en-subtitle= kn-subtitle= en-abstract= kn-abstract=Lentil (Lens culinaris Medik.) is a cool season legume crop that plays vital roles in food and nutritional security, mostly in the least developed countries. Lentil is often cultivated in dry and semi-dry regions, where the primary abiotic factor is drought, which negatively impacts lentil growth and development, resulting in a reduction of yield. To withstand drought-induced multiple negative effects, lentil plants evolved a variety of adaptation strategies that can be classified within three broad categories of drought tolerance mechanisms (i.e., escape, avoidance, and tolerance). Lentil adapts to drought by the modulation of various traits in the root system, leaf architecture, canopy structure, branching, anatomical features, and flowering process. Furthermore, the activation of certain defensive biochemical pathways as well as the regulation of gene functions contributes to lentil drought tolerance. Plant breeders typically employ conventional and mutational breeding approaches to develop lentil varieties that can withstand drought effects; however, little progress has been made in developing drought-tolerant lentil varieties using genomics-assisted technologies. This review highlights the current understanding of morpho-physiological, biochemical, and molecular mechanisms of lentil adaptation to drought stress. We also discuss the potential application of omics-assisted breeding approaches to develop lentil varieties with superior drought tolerance traits. en-copyright= kn-copyright= en-aut-name=NoorMd.

To this end, we conducted a literature survey focusing on Martin Heidegger’s seminal work Sein und Zeit. Through the survey, we could provide examples of learning that creators experience while engaging in dialogue in formative activities. Additionally, we developed a perspective that considers the dialogue related to Das Sein, such as the motifs, impressions, and atmosphere, as linked to the shapes and colors they create.

This study assesses the kinetics of anti-spike protein receptor-binding domain (S-RBD) IgG antibody titers post-booster vaccination in a Japanese population during the Omicron variant epidemic.
Methods: A prospective cohort study was conducted in Bizen City, Japan, from November 2023 to January 2024. Participants included residents and workers aged ≥18 years, with at least three COVID-19 vaccinations. Antibody levels were measured from venous blood samples. The study analyzed 424 participants and 821 antibody measurements, adjusting for variables such as age, sex, underlying conditions, and prior infection status. Mixed-effects models were employed to describe the kinetics of log-transformed S-RBD antibody titers.
Results: The study found that S-RBD antibody titers declined over time but increased with the number of booster vaccinations, particularly those adapted to Omicron and its subvariant XBB.1.5 (Pfizer-BioNTech Omicron-compatible: 0.156, 95%CI −0.032 to 0.344; Pfizer-BioNTech XBB-compatible: 0.226; 95%CI −0.051 to 0.504; Moderna Omicron-compatible: 0.279, 95%CI 0.012 to 0.546; and Moderna XBB-compatible: 0.338, 95%CI −0.052 to 0.728). Previously infected individuals maintained higher antibody titers, which declined more gradually compared to uninfected individuals (coefficient for interaction with time 0.006; 95%CI 0.001 to 0.011). Sensitivity analyses using Generalized Estimating Equations and interval-censored random intercept model confirmed the robustness of these findings.
Conclusions: The study provides specific data on antibody kinetics post-booster vaccination, including the XBB.1.5-adapted vaccine, in a highly vaccinated Japanese population. The results highlight the importance of considering individual demographics and prior infection history in optimizing vaccination strategies. en-copyright= kn-copyright= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiAyako en-aut-sei=Sasaki en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KadowakiTomoka en-aut-sei=Kadowaki en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=SARS-CoV-2 kn-keyword=SARS-CoV-2 en-keyword=Vaccine kn-keyword=Vaccine en-keyword=Antibody kn-keyword=Antibody en-keyword=Mixed-effects model kn-keyword=Mixed-effects model en-keyword=Omicron kn-keyword=Omicron END start-ver=1.4 cd-journal=joma no-vol=37 cd-vols= no-issue=2 article-no= start-page=152 end-page=158 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Death Feigning in Larvae of Scorpionflies (Mecoptera: Panorpidae): Frequency and Postural Changes Based on Larval Instars en-subtitle= kn-subtitle= en-abstract= kn-abstract=Death feigning is thought to have evolved primarily as a predator avoidance behavior, and has been reported in 10 of the 31 orders of insects. However, there have been no reports of death-feigning behavior in Mecoptera species. We found that larvae of two scorpionfly species, Panorpa japonica and P. pryeri, showed death feigning in response to external stimuli by brush poking stimulation. First, we examined the frequencies of death-feigning postures. The two species showed two different postures of death feigning, “straight” and “ball.” Most of the 1st instar larvae of P. japonica and P. pryeri adopted the straight death-feigning posture. Next, we examined duration of death feigning. As the larval instar progressed, the death-feigning posture shifted from straight to ball in both Panorpa species. In P. japonica, the longest durations of death feigning were found in the 2nd to 3rd instars, while the longest duration of death feigning was found in the late 4th instar in P. pryeri larvae. en-copyright= kn-copyright= en-aut-name=IshiharaRyo en-aut-sei=Ishihara en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumuraKentarou en-aut-sei=Matsumura en-aut-mei=Kentarou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Anti-predator behavior kn-keyword=Anti-predator behavior en-keyword=freezing kn-keyword=freezing en-keyword=larvae kn-keyword=larvae en-keyword=thanatosis kn-keyword=thanatosis en-keyword=tonic immobility kn-keyword=tonic immobility END start-ver=1.4 cd-journal=joma no-vol=42 cd-vols= no-issue=3 article-no= start-page=177 end-page=185 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240718 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reduced fitness in losers of leg-biting male combat compared to uncontested males in Zophobas atratus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sexual dimorphism and male combat are observed in many species. Often, the outcome of male combat affects the outcome of subsequent combats, mating success, number of sperm, and fitness of the male’s offspring. Also, the quantity and quality of sperm may be regulated by winning or losing, depending on species ecology and mating system. However, very few studies have experimentally examined the influence of fight outcomes on male offspring fitness. We studied male combat in the giant mealworm (Zophobas atratus) in which males bite each other’s hind legs. We hypothesized that subsequent fitness could differ between winners and losers in the escalated male combat of this species. We measured several fitness traits including the number of eggs laid by mated females, and the number of hatches sired by uncontested males, winners, and losers in escalated and non-escalated combat, and compared the fitness of each winner and loser to that of an uncontested male. We also measured mating duration. The numbers of eggs and the percentages of hatched eggs of losers in the escalated combat were significantly reduced compared to that of the uncontested males. This reduction may be due to injuries from escalated leg- biting fights and a result of the sperm amount of the uncontested males being greater than that of the loser males. en-copyright= kn-copyright= en-aut-name=MatsuuraTeruhisa en-aut-sei=Matsuura en-aut-mei=Teruhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Beetle kn-keyword=Beetle en-keyword=Offspring fitness kn-keyword=Offspring fitness en-keyword=Male combat kn-keyword=Male combat en-keyword=Hind leg kn-keyword=Hind leg en-keyword=Weapon kn-keyword=Weapon END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue=1 article-no= start-page=1 end-page=28 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240724 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Firm Entry and Exit in the First Stage of Regional Vitalization: Revolving Door Economy or Creative Destruction kn-title=地方創生第１期における企業の参入と撤退：回転ドア型経済か創造的破壊か en-subtitle= kn-subtitle= en-abstract= kn-abstract=　The growth of the regional economy needs an economic metabolism in which high-productivity firms newly enter the market, while low-productivity firms exit the market, resulting in a shift in labor and other production factors. A“ revolving door” economy is an economy in which firms that enter the market have a short existence period, withdraw and enter the market repeatedly, and new entrants do not contribute to productivity improvement. This means that if new entrants are not sufficiently innovative compared to incumbents, even if the rate of entry into business rises, they will simply be replaced by firms whose productivity level has not changed much, and this will not lead to job creation or improving productivity. A contrasting concept is the replacement of firms by Schumpeter's “creative destruction.” The high level of technology and productivity of new firms entering the market drives inefficient incumbents out of the market. Looking at the statistics, there is a tendency for both large cities to have higher business entry and exit rates, but the difference between the entry and exit rates is greater in metropolitan areas. Although it depends on the regional characteristics, location competitiveness is generally higher in metropolitan areas, and there is a tendency for the turnover rate to be high or the survival period to be short. Before and after regional revitalization, we will examine whether or not there is a departure from the revolving door economy by industry and region, using economic census and TSR （Tokyo Shoko Research） data. en-copyright= kn-copyright= en-aut-name=NakamuraRyohei en-aut-sei=Nakamura en-aut-mei=Ryohei kn-aut-name=中村良平 kn-aut-sei=中村 kn-aut-mei=良平 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=2400078 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240704 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Unabsorbed Fecal Fat Content Correlates with a Reduction of Immunoglobulin a Coating of Gut Bacteria in High‐Lard Diet‐Fed Mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Scope: Immunoglobulin A (IgA) selectively coats gut bacteria and contributes to regulatory functions in gastrointestinal inflammation and glucose metabolism. Excess intake of lard leads to decrease in the IgA coating of gut bacteria, although the underlying mechanisms remain unknown. This study validates how unabsorbed fat derived from a high-lard diet in the gut affects the IgA coating of bacteria, as assessed in mouse models using three types of dietary fat (lard, medium-, and long-chain triglycerides [MLCTs], and medium-chain triglycerides [MCTs]) exhibiting different digestibilities.
Methods and results: C57BL/6J mice are maintained on diets containing lard, MLCTs, or MCTs at 7% or 30% w/w for 10 weeks (n = 6 per group). The fecal fatty acid concentration is measured to quantify unabsorbed fat content. The ratio of IgA-coated bacteria to total bacteria (IgA coating ratio) in the feces is measured by flow cytometry. Compared to lard-fed mice, MLCT- and MCT-fed mice exhibit lower fecal concentrations of palmitic acid, stearic acid, and oleic acid and higher IgA coating ratios at both 7% and 30% dietary fat, and these parameters exhibit significant negative correlations.
Conclusion: Unabsorbed fat content in the gut may result in attenuated IgA coating of bacteria in high-lard diet-fed mice.

Concrete deteriorates through repeated freezing and thawing, but in salt water, freezing alone leads to destruction. This paper investigated the effect of calcium hydroxide in concrete on the failure of concrete under such low temperatures. Calcium hydroxide precipitates at the transition zone between aggregate and cement paste due to the hydration of cement. The lower the temperature and the higher the concentration of salt water, the more calcium hydroxide dissolves. From concrete, more calcium hydroxide is eluted in salt water than in fresh water. This accelerates the deterioration of mortar and concrete due to freeze-thaw action. Mortar and concrete using ground granulated blast-furnace slag produces less calcium hydroxide. In mortar and concrete using blast-furnace slag sand, calcium hydroxide precipitated around the aggregate reacts with cement paste and blast-furnace slag sand to modify the transition zone. From these results, it was clarified that concrete using blast-furnace slag exhibits high freeze-thaw resistance even in salt water.

kn-abstract=　変革の時代に資する数学力が世界中で叫ばれている。我が国では「数学的な見方・考え方を働かせ､数学的活動を通して､数学的に考える」と数学的に考えることが (2017) が強調されている。これを実現するために、「個別最適な学び、協働的な学び」(2021) が推奨されている。資質・能力と学び方はどちらも重要なことであるが、学び方ばかりに目が向き、数学的に考える指導が洗い流されている。両者を関連付けて同時達成する必要がある。その成否の鍵は､「数学的活動」にあると考える。ところが､数学的活動は、総花的、表層的に捉えられ易い。数学的に考える力を生成するには、活動をどのような視座から数学化すればよいか、数学的に考える力を生成・創発する機能的な数学的活動にするにはどうすればよいか、そのアプローチはまだ解明されていない。そこで、数学的に考える力を生成する真正な「数学的活動のアプローチ」と「変容」の在り方を探究する。
