Using an outcome-wide analytic approach, we examined associations between screen time and 38 adult outcomes, adjusting for prior screen time, values of most outcomes, and confounders. Most associations were null. Modest evidence was found for links between screen time (continuous) and reduced sense of control, illicit drug use, and allostatic load. High screen time (14 h/week) or more also showed weak associations with lower depression and preventive care use. Because the data predate widespread internet use, the findings help establish a baseline for the long-term effects of non-internet screen activities, which appeared to behave had limited impact on adult health and well-being.No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026裏表紙・英文目次ENNo potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026奥付ENNo potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026虢州期の岑参について ―― 心境と詩的表現 ――(59)(74)ENKanakoKUROSE10.18926/70288No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026備中国浅口郡鴨方村高戸家文書目録・史料紹介(39)(57)ENKanakoMASATSUGUYoshihoHONDAMasanobuHIGASHINO10.18926/70287No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026「有翼の天女図」十四考 ― 大正・昭和初期の舞台の羽衣 ―(21)(38)ENYukoTATSUNO10.18926/70286No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026『論語集注』訳注（子罕第九 （二））(1)(20)ENLuyiSUN10.18926/70285No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026墓誌から見た北魏太和後令以後の北朝下位官の遷転175193ENQIANSUN10.18926/70284No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026環境支出は企業リスクを軽減するのか？日本企業の実証分析155174ENYUSRANAZIR10.18926/70283 This study examines how environmental conservation costs (ECC) affects firm risk, using changes in leverage ratios and earnings volatility as stand-ins for risk. This study evaluates the direct impact of ECC and its relationship to profitability (ROA) using panel data of Japanese companies from 2010 to 2022 and Pooled OLS regression models. The results demonstrate the risk-mitigating function of sustainability investments by showing that, although independent ECC have little direct significance, their interaction with firm profitability dramatically lowers earnings volatility and leverage instability. These findings underscore the economic value of environmental strategies, suggesting that incorporating profitability considerations into sustainability practices enhances operational stability and reduces risk exposure. To help policymakers, investors, and corporate managers strike a balance between sustainability and financial performance, this study contributes to the growing body of research on the relationship between the environment and finance.No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026GARCH-MIDAS アプローチによる石油ショックが石油輸入国および輸出国の為替レートに与える影響の分析139153ENPengCHEN10.18926/70282No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026中国の債権者代位訴訟における債務者の手続保障に関する一考察121138ENYANLINGWANG10.18926/70281No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026性役割と両面価値的性差別主義における就業動機との関連101120ENSuzuhaHAPPOKyokoSUMIOKA10.18926/70280No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026写真技術のイノベーションが創出する経済価値8599ENSatoruMIYAZAKI10.18926/70279No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026「国郡志御編集ニ付下調べ書出し帳」にみる広島藩の歌謡田植 ― 大田植の分布と種類に対する一つのアプローチ ―6584ENHiroshiTAKANO10.18926/70278No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026コロナ禍で現地留学中断体験をした日本人学生における心理的変容 ― TEM 図を用いた体験のとらえ直し過程の分析 ―4763ENKoyuriSAKOTomokoTANAKA10.18926/70277No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026南オーストラリア州（アデレード）のリプロダクティブ・ヘルス＆ライツをめぐる現状と課題3146ENKeisukeSAITOSetsukoSUGANO10.18926/70276No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026日本の地方議員における代表性の検討：岡山県地方議員データの分析2129ENYasushiIWABUCHIMichelKoebel10.18926/70275No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026多文化共修のためのグループワークから学生は何を感じたのか？ ― GIS ソフトを使用した地域研究授業からの一考察 ―120ENTakaoINAMORI10.18926/70274No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671612026表紙ENNo potential conflict of interest relevant to this article was reported.岡山大学経済学会Acta Medica Okayama2433-41465732026Environmental Conservation Costs and Operational Efficiency: Evidence from Japanese Manufacturing Firms93109ENYusraNazirDoctoral student at Graduate school of humanities and social sciences, Okayama UniversityTatsumasaTennojiyaFaculty of humanities and social sciences, Okayama University10.18926/OER/70264 This study investigates whether environmental conservation costs (ECC) support the operational effectiveness and financial stability of Japanese manufacturing firms. Using a balanced panel of 128 non-financial companies listed on the Tokyo Stock Exchange from 2010 to 2022, we manually collected firm-level ECC data based on the Ministry of the Environment, Japan's guidelines from sustainability reports and matched them with financial data from Compustat Global/S&P Capital IQ. Applying pooled ordinary least squares regression with firm-level clustered standard errors and winsorized variables, we examine two aspects of performance as measures of operating efficiency and profitability: asset turnover and profit margin. The results show that ECC is positively associated with asset turnover and profit margin, and that the effect is stronger in more profitable companies, substantiating the Resource-Based View that green practices generate competitiveness. These findings contribute to sustainability finance research by going beyond perceptual measures of environmental, social, and governance ratings, and measuring actual firm-level spending on environmental activities, thereby providing more nuanced insights into how environmental practices translate into actual financial performance. This study offers clear managerial and policy implications by showing that transparent environmental conservation costs improve disclosure quality and serve as a measure of improved efficiency and profitability.No potential conflict of interest relevant to this article was reported.岡山大学経済学会Acta Medica Okayama2433-41465732026AI 共生時代における消費者行動の再理論化―AIBCBM フレームワーク―4191ENSawutShazadigulFaculty of Humanities and Social Sciences, Okayama University10.18926/OER/70263 本研究は，AIが意思決定の前段階から介入する環境において，企業・消費者・AIの三者相互作用を体系的に説明する理論枠組みとして，Artificial Intelligence-Based Consumer Behavior Model（AIBCBM）を構築し，提示することを目的とする。まず，既存の消費者行動モデルが，アルゴリズム露出，再帰的学習ループ，AI媒介型社会的影響（Algorithmic Social Influence）といった現代的現象を十分に扱えないという決定的な理論的限界を明らかにする。そのうえで，AI共生時代における消費者行動を，「企業－AI－消費者」の三者循環構造として捉えるAIBCBMを提示する。<br>
モデル構築に際しては，複雑な現実を過度に単純化するのではなく，三者共進化構造モデル（図２），行動生成の動態を示す行動プロセスモデル（表３），概念構造モデル（図３），行動類型モデル（図４）に分離することで，理論的明瞭性と分析可能性を確保した。本研究の理論的貢献は，①System １を行動生成メカニズムとして再定義した点，②意思決定主体と権力構造を再定義した点，③消費者行動における非線形・高速フィードバックループを理論化した点，④非消費やJOMOを，幸福と主体性に根ざした戦略的行動として理論的に再定義した点，⑤消費者行動を「意思決定モデル」から「行動生成モデル」へ理論的に転換した点に集約される。さらに，本研究が提示する，アルゴリズムによる効用の向上と自律性の毀損が併存しうるという二面性は，AI時代におけるマーケティング戦略および政策設計に対して，規範的かつ理論的な新たな評価軸を提供する。AIBCBMは，これらの視座を統合する理論的プラットフォームとして，今後の実証研究に向けた基盤として機能する。とりわけ， AIBCBMは，JOMOや非消費行動を，アルゴリズム環境からの受動的撤退ではなく，AIによって構築された選択環境との距離を意図的に調整し，人間らしさ（人間としての主体性やウェルビーイング）を保持するための戦略的行動として位置づける点に独自性を有する。さらに本モデルは，AI設計（企業側）・アルゴリズム動態（AI側）・主体性とウェルビーイング（Well-being）（消費者側）を同一枠組みで接続することで，AI共生時代の実証研究と規範設計を架橋する理論的座標軸を確立する。No potential conflict of interest relevant to this article was reported.岡山大学経済学会Acta Medica Okayama2433-41465732026地域間での情報交流に関するネットワーク分析：高梁川流域圏での調査による1140ENRyoheiNakamuraNatsumiYokota10.18926/OER/70262 本稿では，岡山県の「高梁川流域連携中枢都市圏」で2014年から開催されている「高梁川流域経済成長戦略会議」における参加主体間の情報交流についてのネットワーク分析を行った。高梁川流域連携中枢都市圏（高梁川流域圏）とは，岡山県高梁川周辺に位置する現在の新見市，高梁市，総社市，早島町，倉敷市，矢掛町，井原市，浅口市，里庄町，笠岡市の10自治体が参加している連携中枢都市圏である。高梁川流域圏におけるネットワーク分析に際しては，同圏域内で展開されている事業を８つに分類し，それぞれの事業に関する参加主体間の情報交流についてアンケート調査を行った。ネットワーク指標については事業ごとに次数中心性と媒介中心性の中心性指標を，また事業別に密度，推移性，相互性を算出した。事業別にみると，観光事業についての情報交流が最も密なネットワーク構造をしており，ネットワークの視点では観光事業が高梁川流域圏内で最も勢力的に行われている事業といえる。また全事業において特定の行政主体や商工会議所をはじめとする地域経済団体等の中心性指標が全体的に大きな値をとっており，ネットワークにおいて情報交流のハブや情報の集中・分散主体として機能していることが明らかになった。分析結果を踏まえ，ネットワークの視点から高梁川流域圏の今度の地域振興について２点提言した。１つは事業によって情報交流のハブや情報の集中・分散主体を主体間で分担することによって，すべての事業で密なネットワークを築くことを目指すことである。もう１つは高梁川流域圏の情報交流ネットワークに全く参加していない主体をなくすことで，全体的に密なネットワークを目指すことである。No potential conflict of interest relevant to this article was reported.岡山大学文学部Acta Medica Okayama0285-4864782025可能表現としての「可能だ」「不可能だ」5162ENKazuhitoMIYAZAKI10.18926/okadai-bun-kiyou/70220No potential conflict of interest relevant to this article was reported.岡山大学文学部Acta Medica Okayama0285-4864782025広島市方言におけるアクセントの継承と変容（1）─ 1 拍・2 拍・3 拍名詞のアクセントの世代的動態 ─3950ENYasueNAKATO10.18926/okadai-bun-kiyou/70219No potential conflict of interest relevant to this article was reported.岡山大学文学部Acta Medica Okayama0285-4864782025戦後80周年の英国の対日戦勝記念日（VJ デイ）の催しおよびドイツ・ベルリンの企画展1328ENTomoyoNAKAO10.18926/okadai-bun-kiyou/70217No potential conflict of interest relevant to this article was reported.Informa UK LimitedActa Medica Okayama1350-46222026Towards place-responsive climate change education: Mongolian primary teachers’ pedagogical judgement across urban and rural contextsENShinetsetsegGerelkhuuGraduate School of Humanities and Social Sciences, Okayama UniversityKhalifatullohFiel’ardhGraduate School of Education, Okayama UniversityHirokiFujiiGraduate School of Education, Okayama UniversityBatchuluunYembuuGeography Department, Mongolian National University of EducationUuriintuyaDembereldorjLifelong Learning and Distance Education Department, Mongolian National University of EducationClimate change education (CCE) in primary schools is increasingly recognised as essential, yet how teachers interpret and enact CCE across diverse local contexts remains underexplored. This study examines how Mongolian primary school teachers working with students aged 6–11 in urban and rural contexts interpret and teach climate change, with particular attention to the role of place. Drawing on semi-structured interviews with 20 teachers across contrasting contexts, the study explores how environmental, cultural, and institutional conditions shape teachers’ pedagogical interpretations and classroom practices. Data were analysed using reflexive thematic analysis, informed by conceptual frameworks that position place as an active mediator of teaching and learning. Findings show that rural teachers frequently integrated traditional ecological knowledge and lived environmental experience to connect global climate processes with locally observable ecological change, emphasising livelihood impacts and intergenerational ecological memory. Urban teachers, by contrast, framed climate change through anthropogenic pressures such as air pollution, waste, and infrastructure constraints, foregrounding feasible individual actions within everyday school contexts. Across both settings, teachers exercised place-responsive pedagogical judgement by selectively adapting climate content to local realities while navigating curriculum constraints and workload pressures. The study contributes a place-responsive account of teachers’ pedagogical judgement in CCE, demonstrating how place functions not only as context but as a condition shaping pedagogical feasibility.No potential conflict of interest relevant to this article was reported.Okayama University Medical SchoolActa Medica Okayama0386-300X8012026Time Course of the Development and Loss of Delta-9-tetrahydrocannabinol Tolerance: Effects on Hypothermia and Spontaneous Locomotor Activity in Mice4754ENYukiomiEguchiDepartment of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka UniversitySoichiroUshioDepartment of Emergency and Disaster Medical Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka UniversityKeiichiIrieDepartment of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka UniversityYutaYamashitaDepartment of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka UniversityMiyuEguchiDepartment of Emergency and Disaster Medical Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka UniversityTakafumiNakanoDepartment of Oncology and Infectious Disease Pharmacy, Faculty of Pharmaceutical Sciences, Fukuoka UniversityKenichiMishimaDepartment of Physiology and Pharmacology, Faculty of Pharmaceutical Sciences, Fukuoka UniversityOriginal Article10.18926/AMO/70072Deregulation of cannabis use is gradually expanding in Europe and the United States. However, the biological processes driving tolerance to delta-9-tetrahydrocannabinol (Δ9-THC), the main psychoactive component of cannabis, remain unclear. Thus, this study aimed to investigate the mechanisms and time course of tolerance development and loss to Δ9-THC in mice. Male ICR mice (7 weeks old) were administered Δ9-THC once daily for 3 days and then divided into three groups according to the washout period (3-, 10-, and 17-day washout groups). After each washout, changes in body temperature and locomotor activity were measured following re-exposure to Δ9-THC. Furthermore, the mRNA expression levels of CB1 and CB2 receptors in the brain were evaluated using real-time PCR. On day 1, significant hypothermia and reduced spontaneous locomotor activity were observed in the Δ9-THC-treated mice compared with the vehicle-treated mice. Tolerance to the hypothermic and locomotor-suppressing effects of Δ9-THC developed on days 2 and 3, respectively, and dissipated after 3 and 11 days of washout, respectively. These differences in the rates of tolerance development and recovery may reflect distinct underlying mechanisms. No significant changes in receptor mRNA expression were observed. These findings highlight the complexity of Δ9-THC tolerance and its potential implications for long-term cannabis use.No potential conflict of interest relevant to this article was reported.Springer Science and Business Media LLCActa Medica Okayama1862-40652026Does Human Depopulation Reduce Resource Consumption? Evidence from Anthropocene JapanENAnassBarrahmouneGraduate School of Humanities and Social Sciences, Faculty of Economics, Okayama UniversityPeterMatanleSchool of East Asian Studies, The University of SheffieldJiyoungKimGraduate School of Humanities and Social Sciences, Faculty of Economics, Okayama UniversityHumanity’s deepening strain on Earth systems has sparked widespread discussion of an “Anthropocene crisis,” often attributed to overpopulation. This raises the question: if overpopulation underpins the crisis, does its resolution lie in depopulation? Here, we examine the effects of Japan’s ongoing depopulation on the nexus of population, economy, cropland use, food, water, and energy. We take a systematic Bayesian approach to examine changes in the strength and direction of causality among these variables and explore plausible future pathways under Shared Socioeconomic Pathway (SSP) scenarios. We find that, while depopulation has led to reductions in resource demand, notably for water and energy, impacts on the food system are more complex due to interdependencies with economic and other factors beyond population change. In conclusion, we argue that it will take longer than predicted for depopulation dividends to materialize at a scale that could meaningfully contribute to addressing the crisis, and that proactive efforts to reshape consumption patterns and restructure economic systems, from a model predicated on perpetual growth to one oriented toward sufficiency, are necessary to capitalize on the potential dividends offered by this demographic shift.No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025裏表紙・英文目次ENNo potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025奥付ENNo potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025菊舎の太宰春台詩受容について(41)(58)ENMENGHUANLI10.18926/70034No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025「有翼の天女図」十三考― 竹内栖鳳による東本願寺御影堂門の天井画とその周辺 ―(21)(39)ENYukoTATSUNO10.18926/70033No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025『論語集注』訳注（子罕第九 （一））(1)(20)ENLuyiSUN10.18926/70032No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025日本語版 The Passive Aggression Scaleの作成および信頼性と妥当性の検討245260ENAyakaSHIGETOUYoung-OkLimKyung-HyunSuhKyokoSUMIOKA10.18926/70031No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025台湾の工業及びサービス業をめぐる低賃金及び賃金格差問題について225244ENHONG TINGCHIANG10.18926/70030No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025日本の一地方の中小企業の貿易・投資相談事例分析― アクションリサーチ及びショーン（1983）の「省察的実践論」を活用した直近三年間の相談事例の現況分析の試み ―205224ENMasaakiNAGAMITSU10.18926/70029No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025「じゃあ」との共起から見た日本語の勧誘文― 談話構造に着目して ―187204ENLizhongXING10.18926/70028No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025科学を担う他者たち：清末科学小説における親縁と鏡像の表象分析169185ENXIAOXUANWU10.18926/70027No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025漢語接尾辞「派」による派生語について― 前接語が固有名詞の場合 ―157168ENXUELI10.18926/70026No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025『本朝小説』における引用の分析― 引用内容と文脈の関連性について ―139156ENJIAJIALIU10.18926/70025No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025現代日本語における「わりに（は）」の用法について129137ENWENHUAYANG10.18926/70024No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025外国人技能実習生のキャリア形成と日本語学習の意味付け― 日本でキャリアを継続するベトナム人技能実習生の語りから ―109128ENNgoc Bich TranHOANG10.18926/70023No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025現代日本語の会話における「で」のフィラー的な使用について89107ENYANGLIU10.18926/70022No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025動作の主体を主語とする難易文について7188ENHUIXINSUN10.18926/70021No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025フッサールの発生的現象学に関する先行研究の整理と比較検討―― 方法論的問題を中心に ――5169ENDaisukeSATO10.18926/70020No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025ライプニッツの「人間学」―『定義集』の叙述を中心に―3150ENTsuyoshiMATSUDA10.18926/70019No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025卑弥呼の残像（下）――明清通俗文学作品に描かれた日本人女性と日本イメージ――1929ENToruYUSA10.18926/70018No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025大田植の分布と種類に関する検討（3）―岡山県・広島県の自治体史等における記述・資料―118ENHiroshiTAKANO10.18926/70017No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671602025表紙ENNo potential conflict of interest relevant to this article was reported.Open Library of the HumanitiesActa Medica Okayama2056-67001212026Racialized Contagion and Defensive Biopolitics in The Last of UsENRobertYeatesFaculty of Humanities and Social Sciences, Okayama UniversityIn the opening moments of the video game The Last of Us Part I, players are introduced to an emerging pandemic via Austin’s Texas Herald newspaper. Below a headline warning of mass hospitalizations from a 'mysterious infection', players read of a recall of imported crops 'potentially tainted with mold': 'Initial lists distributed to vendors nationwide warned against crops imported from South America. However now the scope has extended to include Central America and Mexico'. This scene immediately suggests the racialization of the franchise’s Cordyceps brain infection (CBI), with the
contagion germinating in the global South, invading the US via its southern border, and spreading fastest in the nation’s diverse urban centres. By highlighting tainted crops as the vector of dispersal in the US, however, rather than infected humans, the franchise resists making this a simple invasion-scare narrative and instead suggests that the spread of the infection is in part a result of the capitalist exploitation of cheap land and labour in the global South. Despite its inconsistent record on racial representation and the near-absence of discussion of race across the franchise, the structures reflecting the racialization of contagion and the perpetuation of racialized hierarchies through defensive biopolitics remain present. Drawing connections with the discourse around immigration and the southern border and contemporary pandemics and epidemics, this article makes the case for reading the franchise in terms of racialized contagion and defensive biopolitics, a reading that highlights how the games and their television adaptation reflect urgent contemporary issues around race in America.No potential conflict of interest relevant to this article was reported.岡山大学経済学会Acta Medica Okayama2433-41465722025家族介護者の数と介護時間の推移8192ENKensakuKishida10.18926/OER/69554No potential conflict of interest relevant to this article was reported.岡山大学経済学会Acta Medica Okayama2433-41465722025The Evolution and Challenges of Consumer Behavior Models in the Age of AI Co-Existence4980ENSawutShazadigulFaculty of Humanities and Social Sciences, Okayama University10.18926/OER/69553 This study, based on a theoretical review, aims to elucidate elucidate the structural impact of changes in industrial and social systems, as well as advances in AI technologies, on consumer decision-making and purchasing behavior. It seeks to critically examine the limitations of traditional consumer behavior models that no longer adequately capture contemporary consumption patterns.<br>
Representative models such as AIDMA, AISAS, and SIPS demonstrated explanatory power within the technological and media contexts of their respective eras. However, in the current environment, where AI and algorithms not only deliver information but also shape the structure of choice, these models—built on the assumptions of linearity and rationality, are becoming increasingly insufficient.<br>
This paper provides a comprehensive overview of the theoretical evolution of consumer behavior models from the Mass Media Era to the Age of AI Coexistence. It highlights key limitations, including the neglect of nonlinearity; underestimation of emotional dimensions, such as empathy and resonance; and lack of theoretical responsiveness to the structural constraints imposed by algorithmic environments. Ultimately, this study serves as a theoretical starting point for a paradigm shift in consumer understanding, laying the groundwork for the future reconstruction of theory and he development of innovative marketing strategies in the age of intelligent systems.No potential conflict of interest relevant to this article was reported.岡山大学経済学会Acta Medica Okayama2433-41465722025介護離職の社会的損失―アップデートと時系列推移―116ENKensakuKishida10.18926/OER/69550 Kishida（2020）estimated the number of labor force exiters unemployed due to family care and their lost income. We updated the result of Kishida（2020）and modified the estimation method of the lost income. We defined labor force exiters as those who were out of work 2 years after they exited. The results using the latest Employment Status Survey for 2022 are as follow. Among the 10.6 thousand annual care leavers, 35.9％ restarted work and the remaining 64.1％ exited the labor market. Three-fourths of returned to the exiters were non-regular workers. Among the care leavers previously in regular employment who returned to the labor market, 34.4％ of them restarted work as regular workers and the remainder restarted work as non-regular workers. Among the exiters, the ratio of care leavers to all exiters was 3.8％ . More than 10％ of women exiters of 40-50 years of age were care leavers. Hence, the loss of middle-aged employment due to care leavers is significant.<br>
The wages of care leavers' previous jobs are indispensable for calculating the loss of income. However, our data did not contain the necessary information. Hence, as a proxy variable, we used the wages of workers whose attributes are similar to the ones of the care leavers. Additionally, in the loss of income calculation, we considered the income accrued from restarting work.<br>
The total loss of income during one year after care leave was 187.4 billion yen. We decomposed the income loss into the loss incurred by being unemployed and the loss incurred by getting a job that pays less than the previous one. The former loss was 77.1％ and the latter one was 22.9％ . Approximately 70％ of the income loss due to wage declines was due to previous full-time employment, and 86.3％ of that was due to resuming work as non-full-time employment with significantly lower wages. If the separation period lasts for more than one year, the income loss for society as a whole is the sum of the income losses in the years when the separation period is different. Based on our calculations, the annual income loss was at least 403.2 billion yen.<br>
The number of people leaving the labor market was 74,400 in 2012, 63,700 in 2017, and 68,100 in 2022. In 2012, when the unemployment rate was high, the return to work rate was lower than in 2017 and 2022, and the number of people leaving the labor market was relatively high. Income losses were 382.1 billion yen in 2012, 363.9 billion yen in 2017, and 399.2 billion yen in 2022. The breakdown of income losses by cause was roughly the same.No potential conflict of interest relevant to this article was reported.Elsevier BVActa Medica Okayama1062-9408812026Does innovation-driven policy optimize urban energy consumption? Evidence from China’s innovation-driven city pilot policies102548ENYingnanCongBusiness School, China University of Political Science and LawYufeiHouSchool of Economics, Renmin University of ChinaYuanJiBusiness School, China University of Political Science and LawXiaojingCaiGraduate School of Humanities and Social Sciences, Okayama UniversityRestructuring energy consumption is essential for promoting green, low-carbon economic and societal development. Innovation-driven policies, particularly those implemented in pilot cities, play a crucial role in this transformation. This study conducts a theoretical analysis to examine how such policies influence urban energy-consumption structures. Using a multitime-point difference-in-differences model, it treats China’s national innovation-driven city pilot policies as a quasi-natural experiment. The results indicate that these policies significantly improve urban energy structures. Mechanism analyses reveal that the improvements occur mainly through green innovation and industrial upgrading. Heterogeneity analysis further indicates that the effects are more pronounced in cities with lower administrative tiers, more challenging geographical conditions, and stronger environmental priorities. These findings provide valuable policy insights for refining innovation-driven strategies, enhancing urban energy-consumption structures, and promoting sustainable economic development in China.No potential conflict of interest relevant to this article was reported.Elsevier BVActa Medica Okayama1876-20181082025Introduction to the “Japanese and Western approaches to psychotrauma” symposium104508ENMasanoriNagamineDivision of Behavioral Science, National Defense Medical College Research InstituteTomoyoNakaoGraduate School of Humanities and Social Sciences, Okayama UniversityLeovan BergenFreelance Medical HistorianJunShigemuraFaculty of Health Sciences, Mejiro UniversityTakuSaitoDivision of Behavioral Science, National Defense Medical College Research InstituteFlorentine H.S.van der DoesDepartment of Psychiatry, Leiden University Medical Center (LUMC)MasatoKitanoDivision of Behavioral Science, National Defense Medical College Research InstituteErik J.GiltayDepartment of Psychiatry, Leiden University Medical Center (LUMC)Nic J.van der WeeDepartment of Psychiatry, Leiden University Medical Center (LUMC)EricVermettenDepartment of Psychiatry, Leiden University Medical Center (LUMC)Understandings of psychotrauma have changed throughout medical history, shaped by cultural and social factors. Reviewing transcultural perspectives of psychotrauma helps understand its complexities and contextual impacts. This paper summarizes the Japan–Netherlands symposium on psychotrauma held on March 1, 2024. Despite experiencing psychological trauma from World War II and numerous natural disasters, Japan did not actively research post-traumatic stress disorder (PTSD) for nearly 50 years after the war. The Great Hanshin-Awaji Earthquake and the Tokyo subway Sarin gas attack (1995) popularized the term PTSD in Japan and triggered related research. The absence of psychotrauma research in Japan may reflect a form of state-level PTSD, characterized by avoidance. Japan’s collectivist culture, stigma against seeking psychological help, view of patience as a virtue, survivor guilt, and moral injury were potential related factors. Additionally, sociocultural factors (e.g., insufficient collective grieving and focusing on post-war reconstruction) were discussed as potential hinderances to discussing war experiences. From a European perspective, we examined how “Konzentrationslager” (KZ) syndrome, a trauma-related disorder, evolved independently into diverse conceptual frameworks, ultimately contributing to the acceptance of PTSD following its introduction in 1980. Beyond state compensation for concentration camp survivors, advocacy by feminist movements and veterans' groups increased awareness of psychotrauma across Europe, fostering scholarly research and public discourse. Both PTSD and KZ syndromes are diagnostic categories shaped by specific historical and cultural contexts and should not be regarded as simple, universally applicable medical conditions. They reflect how trauma is interpreted and responded to differently depending on cultural, political, and historical factors.No potential conflict of interest relevant to this article was reported.WileyActa Medica Okayama1367-22232812024Can online interactions reduce loneliness in young adults during university closures in Japan?

However, whether these opportunities contributed to reducing loneliness during the university closures remains unclear, as previous studies have produced contradictory findings. We conducted a nationwide cross-sectional survey. Data were collected on demographics, social environment, social support, interactions, health and loneliness from 4949 students from 60 universities across Japan. We used psychological network and Directed Acyclic Graphs (DAGs) to examine the effect of online interactions on loneliness during university closures during COVID-19. The results showed that the frequency of online interactions with friends did not exert a significant influence on loneliness during university closures. A comparative examination of the DAGs further illuminated that the social environment exhibited fewer pathways for interpersonal interactions and social support during these closure periods. The psychosocial pathways influencing young adults' loneliness show variations contingent on the university's closure status. Notably, the impact of heightened online interactions with friends on loneliness appears to be less pronounced among young adults in the context of university closure.No potential conflict of interest relevant to this article was reported.岡山大学法学会Acta Medica Okayama0386-30507512025エストニアの民族間統合と安全保障問題 ― 「社会意識調査」（2023年５月）の結果に照らして―5622ENY.

This study examined whether power-distance orientation (PDO)—the extent to which individuals accept hierarchical power relations—moderates this association. High-PDO individuals tend to view institutional authorities as entitled to privilege, inclined to engage in patronage relationships and potentially corrupt. We hypothesised that for individuals high in PDO, confidence in institutions could backfire and be linked to the rejection of civic honesty. Using data from 2088 participants across eight countries, we found support for this hypothesis. Specifically, the positive link between institutional confidence and civic honesty was reversed among those who strongly endorse PDO. These findings suggest that individual-level variation in the link between confidence in institutions and civic honesty partly reflects broader beliefs about authorities. We discuss implications of this interaction and outline directions for future research.No potential conflict of interest relevant to this article was reported.岡山大学経済学会Acta Medica Okayama2433-41465712025地域産業連関表における経済波及効果のNew Approach3550ENRyoheiNakamura10.18926/OER/69003 本稿では，まず経済波及効果の考え方について，産業連関表を用いたシミュレーションの結果が，しばしば過大評価になっていることを述べる。その理由として，経済波及効果をもたらす前提条件の考え方にしばしば誤解があることを指摘する。域内の居住者の消費はマネーの移転であり，真の経済効果ではない。波及効果とは，本来，所得が増えた結果の追加消費であって，所得が増えない状況では，代替消費や消費の先取りに過ぎないのである。また，一般にいう経済効果とは，売上高の積み上げであって同じマネーが何でも加算されているものであり，付加価値効果すなわち所得効果とは異なる。付加価値効果は，当初の域外から入ってきたマネー以上にはならない。こういった解釈の誤謬をもたらしているのは，大学での産業連関分析の教育が十分でないことも原因の1つであるが，シンクタンクや公的機関などで提供されている波及効果の計算ツールにも問題がある。そこで本稿では，これまで筆者が提唱してきた波及効果プロセスを見える化するモデルを更に精緻化し，イベントなど外生的インパクトが発生した後の事後的な産業連関表を構築する流れに関して実例を用いて説明を行う。特に自給率の変化の効果については，これまでの競争移入型連関表では効果が過大傾向になる問題点を解消するべく，「部分非競争移入型」の投入構造を提案し，新たな分析方法を提案する。No potential conflict of interest relevant to this article was reported.岡山大学経済学会Acta Medica Okayama2433-41465712025黒字企業と赤字企業における決算発表に対する市場の反応―市場区分変更前後における分析―2133ENToyotakaNakagawaYukiYamanishiHiroakiKobayashi10.18926/OER/69002The purpose of this paper is to examine whether the market reaction to earnings announcements in each market segment （prime market segment, standard market segment, and growth market segment） differs between profitable and loss-making firms around the time of market restructuring. We have previously studied market reactions to quarterly earnings announcements in the context of the revision of market segmentation at the Tokyo Stock Exchange. However, we have not studied the differences between profitable firm quarters and loss firm quarters. Therefore, the analysis in this paper focuses on whether the net income attributable to owners of the parent is positive or negative.

Here, we demonstrate that juvenile-adolescent rats, which naturally engage in social play with peers characterized by rough-and-tumble interactions and 50 kHz ultrasonic vocalizations indicating pleasant sensations, develop a strong affinity for human hands through similar playful contact achieved by repeated tickling with human hands. Using this rat with tickling-induced high affinity for human hands, we discovered that repeated tickling mimicking rough-and-tumble play led to increased oxytocin receptor (OTR) expression in the ventrolateral part of the ventromedial hypothalamus (VMHvl). Inhibition of oxytocin signaling in the VMHvl reduced affinity-like behaviors from rats to human hands. These findings suggest that OTR neurons in VMHvl play an important role in the increase in affinity for human hands induced by pleasant touch sensation with human touch-induced play behavior. Based on retrograde and anterograde tracing studies examining the supraoptic nucleus (SON) and the paraventricular nucleus (PVN) as primary sources of oxytocin, we demonstrate that a subset of oxytocin fibers in the VMHvl originate from the SON, suggesting that affinity-like behavior from rats to human hands may be controlled by oxytocin signaling from magnocellular neurons. Together, this work advances our understanding of how oxytocin shapes social behavior and may inform the development of therapeutic strategies to promote positive social interactions.No potential conflict of interest relevant to this article was reported.Okayama University Medical SchoolActa Medica Okayama0386-300X7922025Lower Work Engagement Is Associated with Insomnia, Psychological Distress, and Neck Pain among Junior and Senior High School Teachers in Japan93100ENRinaTsuchieDepartment of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesMariFukudaDepartment of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesHidekiTsumuraDepartment of Psychology, Graduate School of Technology, Industrial and Social Sciences, Tokushima UniversityMinakoKinutaDepartment of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesTakashiHisamatsuDepartment of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesHideyukiKandaDepartment of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesOriginal Article10.18926/AMO/68647School teachers are subject to both physical and mental health problems. We examined cross-sectional relationships between work engagement and major health outcomes among junior and senior high school teachers in Japan via a nationwide survey in 2019-2020. A total of 3,160 respondents were included in the analyses (19.9% response rate). Work engagement was assessed with the Utrecht Work Engagement Scale-9 (UWES-9), and we thus divided the teachers into quartiles according to their UWES-9 scores. Based on validated questionnaires, we assessed insomnia, psychological distress, and neck pain as health outcomes. A binomial logistic regression adjusted for age, gender, school type, teacher’s roles, involvement in club activities, division of duties, employment status, and whether they lived with family demonstrated that the teachers with lower UWES-9 scores had higher burdens of insomnia, psychological distress, and neck pain (odds ratios [95% confidence intervals] in 4th vs. 1st quartile, 2.92 (2.34-3.65), 3.70 (2.81-4.88), and 2.12 (1.68-2.68), respectively; all trend p<0.001). There were no significant differences in these associations between full-time and part-time teachers. Our findings indicate that low work engagement may contribute to physical and mental health issues among junior and senior high school teachers, thus providing insights for preventing health problems in this profession.No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671592025裏表紙・英文目次ENNo potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671592025奥付ENNo potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671592025明治初年における岡山藩の常備軍編成 ―銃隊を中心に―(1)(15)ENKanakoMASATSUGU10.18926/68546No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671592025西夏軍制における「軍」の機能 ―「軍」に属する地位名称および「職」との関係―143163ENHirokoONO10.18926/68545No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671592025秦漢時代における官吏の処罰 ―「廢」と「免」を中心に―123141ENCongLIU10.18926/68544No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671592025The Impact of Free Government Healthcare Insurance on The Utilization of Healthcare Services in Vietnam101122ENDo Thi Hoai Giang10.18926/68543 This study investigates the impact of the Free Government Healthcare Insurance (FGHI) scheme on healthcare utilization patterns among enrolled households. Utilizing Tobit regression and Nearest Neighbor Matching (NNM), the analysis revealed a significant positive correlation between scheme enrollment and increased healthcare checkup frequency. However, demographic and geographic variations were evident in the scheme's impact, with ethnic minorities and rural households experiencing a more pronounced rise in healthcare visits compared to the majority group and urban residents. These findings underscore the necessity for tailored policy interventions to address disparities across diverse demographic and geographic strata. Moreover, the FGHI scheme demonstrated effectiveness in encouraging healthcare utilization, particularly among specific demographic groups.

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.No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024裏表紙・英文目次ENNo potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024奥付ENNo potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024菊舎の上⺒詩諧と「桃花源記」(19)(28)ENMenghuanLI10.18926/68315No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024『論語集注』（朱熹撰）の日本語訳（述而第七 下篇（下））―『論語集注』を主とする朱子の『論語』解釈―(1)(17)ENLuyiSUN10.18926/68314No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024国内外の文献レビューを通した恋愛関係喪失体験からの回復に関する要因と過程213232ENAsumiKIMURAMikayoANDO10.18926/68313No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024「多言語母語の日本語学習者横断コーパス（I − JAS）」から見た日本語学習者の会話における「で」の使用実態について―日本語母語話者との比較を通じて―195212ENYangLIU10.18926/68312No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024食品ロス削減キャンペーンの効果検証―縦断データによる２種類の消費者行動分析からの考察―175193ENMasashiKANDA10.18926/68311No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024『唐詩選』収録作品の主題―『古文真宝』との比較を通じて―155173ENYanyanMA10.18926/68310No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024中国民法典成立後の債権者代位訴訟の手続法問題135154ENYANLINGWANG10.18926/68309No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024介護士に必要なソーシャルスキル――教育実践に向けた研究課題の展望――119134ENSayumiMIYAKEYoichiYAMANOTomokoTANAKA10.18926/68308No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024隠れたカリキュラムによるジェンダー再生産のメカニズム―知識伝達と再生産に着目して―103118ENHeqiaoWANG10.18926/68307No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024現代若者の自然会話におけるぼかし表現の使用実態―性差に着目して―91102ENKainanWANG10.18926/68306No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024Exploring the Link Between Modern Household Amenities and Health in Vietnam7189ENDo Thi Hoai Giang10.18926/68305 The correlation between the impact of the external and internal environment of a household on its occupants’ health has been well documented by various research studies. Yet a limitation of the literature is the prevalence of modern household basic amenities and occupant health, especially in Vietnam. This paper examines the impact of modern household basic amenities on occupant health by applying the Vietnam Household Standard Survey 2018. By applying the Tobit method, it is revealed that household amenities displayed a significant association with health outcomes. For instance, individuals residing in concrete houses or employing waste collection systems exhibited decreased illness likelihood. Handwashing with soap correlated with a diminished illness probability. Tobit analysis highlights internet accessibility as significant in reducing days of work incapacity (approximately 6 days less). Gender, residential location, and total income also impact workdays. Age and education exhibit inverse relationships with workdays missed. In essence, these findings contribute to the broader discourse on public health and underscore the importance of considering diverse factors, ranging from basic amenities to socio-economic indicators, in formulating comprehensive health policies and interventions.No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024動作の対象を主語とする難易文について5370ENHuixinSUN10.18926/68304No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024統合型日本語語彙データベースJ-CLID:C4の構築3352ENJianhuiLU10.18926/68303No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024卑弥呼の残像（中）―明清通俗文学作品に描かれた日本人女性と日本イメージ―2531ENToruYUSA10.18926/68302No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024ヘーゲルの和解概念・1―キリスト教における和解の教義―1524ENAyumiTAKESHIMA10.18926/68301No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024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（前半）――113ENKeisukeSAITO10.18926/68300No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671582024表紙ENNo potential conflict of interest relevant to this article was reported.岡山大学文学部Acta Medica Okayama0285-4864772024論理可能と推論─「してもおかしくない」「しても不思議はない」─6575ENKazuhitoMIYAZAKI10.18926/okadai-bun-kiyou/67920No potential conflict of interest relevant to this article was reported.岡山大学経済学会Acta Medica Okayama2433-41465622024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4171ENRyoheiNakamuraTakeshiNagamuneSyuseiHayashi10.18926/OER/67707 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.No potential conflict of interest relevant to this article was reported.岡山大学法学会Acta Medica Okayama0386-30507412024エストニア共和国における移民問題の現状と課題― 「暴動」（2007年）以後の統合政策の展開を通して―8653ENY.KawaharaNo potential conflict of interest relevant to this article was reported.岡山大学経済学会Acta Medica Okayama2433-41465612024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128ENRyoheiNakamura10.18926/OER/67485 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.No potential conflict of interest relevant to this article was reported.WileyActa Medica Okayama2688-6146542024Combination of reduced post-transplant cyclophosphamide and early tacrolimus initiation increases the incidence of chronic graft-versus-host disease in human leukocyte antigen-haploidentical peripheral blood stem-cell transplantation810814ENToshikiTeraoDepartment of Hematology and Oncology, Okayama University HospitalTakumiKondoDepartment of Hematology and Oncology, Okayama University HospitalMakotoNakamuraDepartment of Hematology and Oncology, Okayama University HospitalHirokiTakasukaDepartment of Hematology and Oncology, Okayama University HospitalHideakiFujiwaraDepartment of Hematology and Oncology, Okayama University HospitalNoboruAsadaDepartment of Hematology and Oncology, Okayama University HospitalDaisukeEnnishiDepartment of Hematology and Oncology, Okayama University HospitalHisakazuNishimoriDepartment of Hematology and Oncology, Okayama University HospitalKeikoFujiiDepartment of Hematology and Oncology, Okayama University HospitalNobuharuFujiiDepartment of Hematology and Oncology, Okayama University HospitalYoshinobuMaedaDepartment of Hematology and Oncology, Okayama University HospitalKen-IchiMatsuokaDepartment of Hematology and Oncology, Okayama University HospitalWe evaluated the clinical impacts of the concurrent modification of post-transplant cyclophosphamide (PTCy) dose and tacrolimus (Tac)-initiation timing in 61 patients with human leukocyte antigen-haploidentical transplantation. Reduced-dose PTCy (80 mg/kg) was associated with a higher incidence of moderate-to-severe chronic graft-versus-host disease (GVHD) than standard-dose PTCy (100 mg/kg) (35.0% vs. 26.6%, p = 0.053). Notably, early-initiation Tac (day -1) increased moderate-to-severe chronic GVHD than standard-initiation Tac (day 5) in the reduced-dose PTCy group (p = 0.032), whereas Tac-initiation timing did not impact chronic GVHD in the standard-dose PTCy group. These data indicate that the combination of reduced-dose PTCy and early-initiation Tac can amplify chronic GVHD.No potential conflict of interest relevant to this article was reported.Springer Science and Business Media LLCActa Medica Okayama1352-47392024The optimum quantity of debt for an aging Japan: welfare and demographic dynamicsENAkiraOkamotoFaculty of Economics, Okayama UniversityJapan’s government is heavily indebted, and the current net debt tends to increase. This paper uses an extended life-cycle general equilibrium model with endogenous fertility to investigate an optimal size of government debt from two viewpoints: individual welfare and future demographic dynamics. A simulation analysis finds that the level of net government debt, which maximizes per-capita utility, is negative at − 220% of Japan’s gross domestic product (GDP). The results also indicate that the net debt-to-GDP ratio of − 220% produces a considerable per-capita welfare gain; however, compared to the baseline simulation with a debt-to-GDP ratio of 150%, it substantially decreases the total population in the long run.No potential conflict of interest relevant to this article was reported.Springer Science and Business Media LLCActa Medica Okayama0167-680620232023Prognostic impact of adjuvant endocrine therapy for estrogen receptor-positive and HER2-negative T1a/bN0M0 breast cancer473483ENShinsukeSasadaDepartment of Surgical Oncology, Research Institute for Radiation Biology and Medicine, Hiroshima UniversityNaotoKondoDepartment of Breast Surgery, Nagoya City University Graduate School of Medical SciencesHiroyaHashimotoCore Laboratory, Nagoya City University Graduate School of Medical SciencesYukoTakahashiDepartment of Breast and Endocrine Surgery, Okayama University HospitalKaoriTerataDepartment of Breast and Endocrine Surgery, Akita University HospitalKumikoKidaDepartment of Breast Surgical Oncology, St. Luke’s International HospitalYasuakiSagaraDepartment of Breast and Thyroid Surgical Oncology, Social medical corporation Hakuaikai, Sagara HospitalTakayukiUenoBreast Oncology Center, The Cancer Institute Hospital of Japanese Foundation for Cancer ResearchKeiseiAnanDepartment of Surgery, Kitakyushu Municipal Medical CenterAkihikoSutoDepartment of Breast Surgery, National Cancer Center HospitalChizukoKanbayashiDepartment of Breast Oncology, Niigata Cancer Center HospitalMinaTakahashiDepartment of Breast Oncology, National Hospital Organization Shikoku Cancer CenterRikiyaNakamuraDepartment of Breast Surgery, Chiba Cancer CenterToshiyukiIshibaDepartment of Breast Surgery, Tokyo Metropolitan Cancer and Infectious Diseases Center, Komagome HospitalMichikoTsuneizumiDepartment of Breast Surgery, Shizuoka General HospitalSeiichiroNishimuraDepartment of Breast Surgery, Shizuoka Cancer Center HospitalYoichiNaitoDepartment of General Internal Medicine, National Cancer Center Hospital EastFumikataHaraBreast Oncology Center, The Cancer Institute Hospital of Japanese Foundation for Cancer ResearchTadahikoShienDepartment of Breast and Endocrine Surgery, Okayama University HospitalHirojiIwataDepartment of Breast Oncology, Aichi Cancer Center HospitalPurpose Mammography screening has increased the detection of subcentimeter breast cancers. The prognosis for estrogen receptor (ER)-positive and human epidermal growth factor receptor 2 (HER2)-negative T1a/bN0M0 breast cancers is excellent; however, the necessity of adjuvant endocrine therapy (ET) is uncertain.<br>
Methods We evaluated the effectiveness of adjuvant ET in patients with ER-positive and HER2-negative T1a/bN0M0 breast cancer who underwent surgery from 2008 to 2012. Standard ET was administrated after surgery. The primary endpoint was the cumulative incidence of distant metastasis. All statistical tests were 2-sided.<br>
Results Adjuvant ET was administered to 3991 (83%) of the 4758 eligible patients (1202 T1a [25.3%] and 3556 T1b [74.7%], diseases). The median follow-up period was 9.2 years. The 9-year cumulative incidence of distant metastasis was 1.5% with ET and 2.6% without ET (adjusted subdistribution hazard ratio [sHR], 0.54; 95% CI, 0.32–0.93). In multivariate analysis, the independent risk factors for distant metastasis were no history of ET, mastectomy, high-grade, and lymphatic invasion. The 9-year overall survival was 97.0% and 94.4% with and without ET, respectively (adjusted HR, 0.57; 95% CI, 0.39–0.83). In addition, adjuvant ET reduced the incidence of ipsilateral and contralateral breast cancer (9-year rates; 1.1% vs. 6.9%; sHR, 0.17, and 1.9% vs. 5.2%; sHR, 0.33).<br>
Conclusions The prognosis was favorable in patients with ER-positive and HER2-negative T1a/bN0M0 breast cancer. Furthermore, adjuvant ET reduced the incidence of distant metastasis with minimal absolute risk difference. These findings support considering the omission of adjuvant ET, especially for patients with low-grade and no lymphatic invasion disease.No potential conflict of interest relevant to this article was reported.Okayama University Medical SchoolActa Medica Okayama0386-300X7822024The Relationships among Internalized Stigma, Sense of Coherence, and Personal Recovery of Persons with Schizophrenia Living in the Community171184ENAyaKuramotoGraduate School of Health Sciences, Okayama UniversityShinyaSaitoGraduate School of Health Sciences, Okayama UniversityKumiWatanabeSchool of Nursing, Faculty of Medicine, Kagawa UniversityOriginal Article10.18926/AMO/66926We investigated (i) the relationships among internalized stigma (IS), sense of coherence (SOC), and the personal recovery (PR) of persons with schizophrenia living in the community, and (ii) how to improve the support for these individuals. A questionnaire survey on IS, SOC, and PR was sent by mail to 270 persons with schizophrenia living in the community who were using psychiatric daycare services, of whom 149 responded and 140 were included in the analysis. We established a hypothetical model in which IS influences PR, and SOC influences IS and PR, and we used structural equation modeling to examine the relationships among these concepts. The goodness of fit was acceptable. Our findings suggest that rather than directly promoting PR, SOC promotes PR by mitigating the impact of IS. It is important for nurses/supporters to support individuals with schizophrenia living in the community so that they have opportunities to reflect on their own experiences through their activities and to share their experiences with peers. Nurses/supporters themselves should also reflect on their own support needs. Our findings suggest that this will lead to a reduction of IS and the improvement of SOC, which will in turn promote personal recovery.No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024裏表紙・英文目次ENNo potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024奥付ENNo potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024源琦筆「妖怪絵巻」に見られる大頭の妖怪の図像の伝播(61)(75)ENShokoTSUTSUMI10.18926/66839No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024「有翼の天女図」十一考―明治後期の諸相―(41)(60)ENYukoTATSUNO10.18926/66838No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024『論語集注』（朱熹撰）の日本語訳（述而第七 下篇（上））――『論語集注』を主とする朱子の『論語』解釈――(21)(39)ENLuyiSUN10.18926/66837No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024近世後期～明治期における山間部豪農の経営とネットワーク―備中国川上郡宇治村仲田家文書の紹介を兼ねて―(1)(19)ENMasanobuHIGASHINO10.18926/66836No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024RCEPの日中サービス貿易に与える影響についての研究183197ENWenjunNIU10.18926/66835No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024社会ネットワークとISO15189認定取得との関連169181ENHiroyoNAGATA10.18926/66834No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024日本のコンテナターミナルにおける港湾荷役の高度化に関する動向149167ENHirokiMORIYAMA10.18926/66833No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024岡山県北東部における地域食文化の変遷―旧大原町と西粟倉村の秋祭りを事例として―127148ENShigekoHOSHIJIMA10.18926/66832No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024利用者が介護士へ信頼感を抱く場面に関する質的研究―介護士の対人関係形成能力の向上のための心理教育法開発に向けて―111126ENSayumiMIYAKETomokoTANAKA10.18926/66831No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024形容詞修飾語用法の不規則性について―規定語・述語用法との比較から―89109ENKazumiKATO10.18926/66830No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024卑弥呼の残像（上）――明清通俗文学作品に描かれた日本人女性と日本イメージ――7587ENToruYUSA10.18926/66829No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024可能性と否定―動詞「限る」の否定形―5973ENKazuhitoMIYAZAKI10.18926/66828No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024進路選択における自己効力感、ソーシャルスキル、EIの関係に関する考察―コロナ禍における3年間の大学生データを基にして―4158ENHisashiMACHIDA10.18926/66827 進路選択における先行研究では、進路選択能力を高めることにより進路選択行動が活発化し、そこに進路選択自己効力感が媒介するとより進路選択行動が高まるなど多様な研究成果が報告されてきた（富永, 2009）。先行研究を踏まえて筆者らはこれまでMachida, H., & Hirakimoto, H.（2017）、Machida, H.（2021） などにおいて、大学生などの進路選択自己効力感を高める因子としてのソーシャルスキルの存在を明らかにしてきた。しかしながら2020年以降のコロナ禍においては、大学生は学業の場のみならず、課外活動やアルバイトの場においても対人関係を深める活動が制限されると共に、コミュニケーションの機会が失われ、ソーシャルスキルを高める機会は低減した。筆者らはこのような環境下においてもソーシャルスキルを高める因子としてのEI（感情知性）に着目し、2021年度の調査を基礎に町田・開本（2022）においてEI（感情知性）とソーシャルスキル並びに進路選択自己効力感の関係について明らかにしてきた。その後2021年からの3年に渡る、ソーシャルスキルに加えEI（感情知性）が大学生の進路選択自己効力感にどのような影響を及ぼしているかについて明らかにすることを目的に、大学生を対象にサーベイ調査を継続してきた。結果的にEI（感情知性）はソーシャルスキルを媒介して進路選択自己効力感に正の影響を及ぼすことが3年間の継続調査により明らかになった。No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024本邦における質問紙を用いた心理学的縦断研究の概観2140ENKyokoSUMIOKAHirotoYAMAUCHI10.18926/66826No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024TEIとRDFを用いたアラビア文字伝記資料のデータ化の試み―イブラーヒーム・クーラーニーの伝記を例に―120ENYuriISHIDA10.18926/66825No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671572024表紙ENNo potential conflict of interest relevant to this article was reported.岡山大学法学会Acta Medica Okayama0386-30507342024令状請求における虚偽情報と，善意の例外446424ENK.

The economic base model has some conditional assumptions while it is quite tractable.<br>
Recently, papers by Moretti and others show significant regional multiplier effects of innovative jobs. They refocused on the traditional economic base model. However, their approach has several deficiencies concerning the identification of basic/non-basic industries and ambiguity of multiplier generating mechanisms.<br>
This paper focuses on regional specialization of knowledge intensive industries and creative jobs which are the driving forces of regional development in the framework of the economic base model. The estimations of regional economic multiplier in terms of employment are carried out using two-digit employment and three-digit job classification data at local municipality level with two-period data. Using these data, I explain regional differences by degree of specialization of knowledge intensive industries and creative workers. By doing this, I propose contemporary regional economic policy. Furthermore, by comparing multiplier effects at local municipality level and regional employment area level, benefits of municipal consolidation are shown.No potential conflict of interest relevant to this article was reported.Okayama University Medical SchoolActa Medica Okayama0386-300X7812024Quantitative Assessment of the Heat Transfer Capacity of Ice Bags and their Cooling Effects on the Skin Surface and Core Temperature5361ENYukikoIchikawaDepartment of Nursing Science, Faculty of Health and Welfare Science, Okayama Prefectural UniversityTetsuyaOginoDepartment of Nursing Science, Faculty of Health and Welfare Science, Okayama Prefectural UniversityOriginal Article10.18926/AMO/66671Ice bags are frequently used in medical care settings for pain relief, comfort, and in some cases, whole-body cooling. This study quantifies heat energy transfer capacity of ice bags and evaluates their cooling effects on body temperature. Forty-eight healthy adults in their 20s were recruited. An ice bag wrapped in two layers of dry towel was applied to the forehead, neck, or palm of each participant for 10 min. The skin surface temperature, heat flow, and core temperature were recorded during the cooling and non-cooling periods, with energy transfer calculated by integrating heat flow over time. Over the non-cooling period, 31.4-53.6 kJ·m-2 of energy was dissipated over 10 min, whereas during the cooling period, the range increased to 180.0-218.7 kJ·m-2 over 10 min. Skin surface temperature decreased by 3.2-5.7°C, whereas core temperature was unchanged. Ice bag use augmented energy transfer by about 150-180 kJ·m-2 over 10 min, but this was insufficient for rapid whole body cooling due to the small skin-surface area in contact with the ice bag. The measured energy transfer indicated that topical ice bag application absorbs insufficient energy to affect core temperature. Quantitative assessment of energy transfer was shown to inform the safe and appropriate use of thermotherapy.No potential conflict of interest relevant to this article was reported.Elsevier BVActa Medica Okayama2352-409X532024Multi-isotopic analysis of domestic burials from sin Cabezas, Escuintla, Guatemala104348ENShintaroSuzukiResearch Institute for the Dynamics of Civilizations, Okayama UniversityTomásBarrientosCentro de Investigaciones Arqueológicas y Antropológicas, Universidad del Valle de GuatemalaHéctorMejíaTransportadora de Energía de Centroamérica, Universidad de San Carlos de GuatemalaT. DouglasPriceUniversity of WisconsinWe present the results from the stable isotope measurements of strontium (87Sr/86Sr) and oxygen (δ 18O) in tooth enamel from 36 individuals from the site of Sin Cabezas, Escuintla, Guatemala. This is the first contribution of isotopic proveniencing from the Pacific Coast of Guatemala and offers new solid baseline reference data from a large archaeological sample. Although some outlier cases are identified, the high homogeneity is the most evident feature in the sample. Based on this homogeneity, we discuss a critical issue of baseline data between Teotihuacan and the Pacific Coast, where the material culture has indicated intimate cultural interactions. A critical overlap for both strontium and oxygen reference between the Mexican metropolis and the coastal region is pointed out. This is why detecting human movement between both regions is still elusive. A case study of a possible Mexican individual is introduced. We also assess the outlier cases in terms of proveniencing and add several osteobiographic notes for the most relevant cases whose origin could be seen among the Northern - Eastern part of the Guatemalan Highlands, the Soconusco border region, or Central Honduras.No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671562023裏表紙・英文目次ENNo potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671562023奥付ENNo potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671562023「有翼の天女図」九考―狩野芳崖の天人図画稿再論―(23)(36)ENYukoTATSUNO10.18926/66522No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671562023『論語集注』（朱熹撰）の日本語訳（述而第七 上篇）―『論語集注』を主とする朱子の『論語』解釈―(1)(12)ENLuyiSUN10.18926/66521No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671562023希求文におけるモーダルな意味の広がり―主体が二人称、三人称の場合―107125ENSeiryuMIYAGI10.18926/66520No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671562023会話における接続詞「で」の文脈展開機能89106ENYANGLIU10.18926/66519No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671562023大学生のオンライン授業と対面授業におけるストレスの構造―新型コロナウイルス感染症の感染急拡大と消退を踏まえて―7388ENHirotoYAMAUCHIMikayoANDO10.18926/66518No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671562023中山間地域における公共交通維持に係る地域的対応―岡山県美作市を例に―5372ENKatsumiKATAOKA10.18926/66517No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671562023Collapse of Groups due to the COVID-19 Pandemic and Group Resilience in Varsity Sports Teams3751ENMikiOzekiFaculty of Humanities and Social Sciences, Okayama UniversityRisakoYoshimuraThe Joint Graduate School (Ph.D. Program) in Science of School Education Hyogo University of Teacher EducationHarukoSakoFaculty of Education, Okayama University10.18926/66516No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671562023外来語の連濁について1736ENJianhuiLU10.18926/66515No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671562023知的障害のある子供に対する主権者教育の原理の構築―自立的意思決定を保障するプログラム開発のためのフレーム・ワークの構築を目指して―116ENToshinoriKUWABARA10.18926/66514No potential conflict of interest relevant to this article was reported.岡山大学大学院社会文化科学研究科Acta Medica Okayama1881-1671562023表紙ENNo potential conflict of interest relevant to this article was reported.岡山大学文明動態学研究所Acta Medica Okayama2436-832632024中洲の形成と中世後期の地域変容6066ENToshifumiYATANiigata University, Humanities and Social Sciences特集：災害と文明・地域社会 (Special Issue: Disasters, civilization, and local society)10.18926/66192The purpose of this paper is to clarify how a harbor city established in a sandbank inlet transformed a local area. In the Later Medieval period, the harbor city of Nakamura was established in the lower part of the Chikusa river. In the late 15th century, the Eiōji temple of Jōdo Shinshū Buddhism was constructed in the harbor city of Nakamura. Nakamura used Sagoshinoshō as a local name. In the 16th century, the harbor city of Kariya on the west coast of the Chikusa river also used the local name of Sagoshinoshō. In the early modern period, villages to the west of the mouth of the Chikusa river came to use the local name of Sagoshinoshō. While the local name of the west coastal area of the Chikusa river mouth had been Akōnoshō, it changed to Sagoshinoshō. Areas where local names may have changed also include Shikatanoshō and Mikuriyanoshō elsewhere in the Later Medieval period.No potential conflict of interest relevant to this article was reported.岡山大学文明動態学研究所Acta Medica Okayama2436-832632024災害と人間の暮らし5559ENKatsunoriIMAZU特集：災害と文明・地域社会 (Special Issue: Disasters, civilization, and local society)10.18926/66191No potential conflict of interest relevant to this article was reported.岡山大学文明動態学研究所Acta Medica Okayama2436-832632024How is subjective well-being affected by different factors and groups: Income threshold induces asymmetric effects120ENMasaoTSURIFaculty of Economics, MUSASHI UNIVERSITYKenAOOGraduate School of Humanities and Social Sciences, OKAYAMA UNIVERSITY論文 (Research article)10.18926/66188Holistic well-being has rapidly developed in the 21st century as a policy measurement tool. Nevertheless, there continue to be some gaps in the literature regarding the interrelation between subjective well-being and other factors, and, regarding disaggregation of the well-being status within a country, by age group, gender, and community. This study first illustrates how the concept of well-being developed from a philosophical and psychological conception of “happiness” to being measured by multidimensional tools that measure the impact of policy and the progress of society, such as OECD’s Better Life Index, UK’s National Well-being Measurement, and Japan’s Well-being Survey and Quality of Life. Subsequently, it analyzes the relationships between subjective well-being and objective variables by comparing the country, regional, and individual datasets. It found that some indicators, such as social relationships, have asymmetric effects on life satisfaction depending on the income level or threshold. In other words, if the income is less than a certain level, the effects of some indicators on life satisfaction are complementary to income, while if the income is above that level, the effects are substitutional. Finally, it estimates these effects and confirms them statistically by using the OECD Regional Statistics. Regarding the relationship between social connection and self-evaluation of life satisfaction rated on a 10-point Likert scale, the base score in the estimation is approximately 5.1 points higher in the lowest quartile group of income. However, the substitution is lower than that of the other groups by approximately -0.061. The coefficient of social connection for the other groups was approximately 0.059, and the lowest group had almost zero coefficients for substitution.No potential conflict of interest relevant to this article was reported.Okayama University Medical SchoolActa Medica Okayama0386-300X7762023Japanese Nursing Staff’s Knowledge and Attitude toward Bereavement Care for Couples with Miscarriage/Stillbirth and Its Associated Factors577587ENSiyuLiuGraduate School of Health Sciences, Okayama UniversityRukmaliAthurupanaGraduate School of Health Sciences, Okayama UniversityHongmeiHanGraduate School of Health Sciences, Okayama UniversityTitiYangGraduate School of Medicine, Density and Pharmaceutical Sciences, Okayama UniversityMikiyaNakatsukaGraduate School of Health Sciences, Okayama UniversityOriginal Article10.18926/AMO/66149Bereavement care is conducted to meet the emotional needs of grieving couples who are devastated by the experience of a miscarriage or stillbirth. From January to April 2022, we distributed a questionnaire that assessed the knowledge and attitudes of Japanese nursing staff (nurses and midwives) in Japan’s Chugoku-Shikoku region toward bereavement care for couples with miscarriage/stillbirth. The 370 survey respondents’ answers revealed that the nursing staff’s knowledge regarding recurrent pregnancy loss and subsequent bereavement care was insufficient. About 41.1% and 64.1% of the respondents had received school and on-the-job education in bereavement care, respectively, and 79.2% expressed willingness to provide such care. Our analyses revealed that the following factors were associated with the nursing staff’s knowledge level: parent status, age, reproductive history, midwifery license, work experience and environment, and on-the-job education. The following were correlated with the staff’s willingness to provide bereavement care: work environment, midwifery license, bereavement care knowledge, and on-the-job education. Together our findings indicate that education plays a significant role in equipping caregivers to provide effective bereavement care for couples who have experienced a miscarriage or stillbirth.No potential conflict of interest relevant to this article was reported.Springer Science and Business Media LLCActa Medica Okayama0014-481924032022Global surface features contribute to human haptic roughness estimations773789ENHuazhiLiGraduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama UniversityJiajiaYangGraduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama UniversityYinghuaYuGraduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama UniversityWuWangSchool of Psychological and Cognitive Sciences, Peking UniversityYulongLiuGraduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama UniversityMengniZhouGraduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama UniversityQingqingLiDepartment of Teacher Education, Wenzhou UniversityJingjingYangSchool of Computer Science and Technology, Changchun University of Science and TechnologyShipingShaoSchool of Social Welfare, Yonsei UniversitySatoshiTakahashiGraduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama UniversityYoshimichiEjimaGraduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama UniversityJinglongWuGraduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama UniversityPrevious studies have paid special attention to the relationship between local features (e.g., raised dots) and human roughness perception. However, the relationship between global features (e.g., curved surface) and haptic roughness perception is still unclear. In the present study, a series of roughness estimation experiments was performed to investigate how global features affect human roughness perception. In each experiment, participants were asked to estimate the roughness of a series of haptic stimuli that combined local features (raised dots) and global features (sinusoidal-like curves). Experiments were designed to reveal whether global features changed their haptic roughness estimation. Furthermore, the present study tested whether the exploration method (direct, indirect, and static) changed haptic roughness estimations and examined the contribution of global features to roughness estimations. The results showed that sinusoidal-like curved surfaces with small periods were perceived to be rougher than those with large periods, while the direction of finger movement and indirect exploration did not change this phenomenon. Furthermore, the influence of global features on roughness was modulated by local features, regardless of whether raised-dot surfaces or smooth surfaces were used. Taken together, these findings suggested that an object’s global features contribute to haptic roughness perceptions, while local features change the weight of the contribution that global features make to haptic roughness perceptions.No potential conflict of interest relevant to this article was reported.Okayama University Medical SchoolActa Medica Okayama0386-300X7752023Participation in the Setouchi Triennale and the Health of Residents in Naoshima: A Cross-Sectional Study491497ENHiroshiHabuDepartment of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesSoshiTakaoDepartment of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesChikaraMiyajiDepartment of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesNaomiMatsumotoDepartment of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesKenAooGraduate School of Humanities and Social Sciences, Okayama UniversityYosukeNishitaGraduate School of Humanities and Social Sciences, Okayama UniversityMasaoTsuriFaculty of Economics, Musashi UniversityTakashiYorifujiDepartment of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesOriginal Article10.18926/AMO/65971Arts festivals have become increasingly popular in various parts of Japan in recent years. The purpose of this study was to investigate the relationships between arts festival activities participation at the Setouchi Triennale and the health of residents in the town of Naoshima. This was a cross-sectional study. Questionnaires were distributed to all residents of Naoshima who were 20 years old or older (n=2,588). We analyzed responses from 708 people. The associations between arts festival activities participation and health (measured by self-rated health) were analyzed using logistic regression analysis as the primary outcome. Kessler’s psychological distress scale scores were also analyzed in the same manner as the primary outcome. The participating group had an adjusted odds ratio of 1.86 (95% confidence interval: 1.03-3.33) for higher self-rated health compared with those who did not participate. Kessler’s psychological distress scale results showed that the participating group had an adjusted odds ratio of 3.23 (95% confidence interval: 1.19-8.81) for lower psychological distress compared with those who did not participate. In conclusion, arts festival activities participation was associated with higher self-rated health and lower psychological distress. However, caution must be taken in regard to generalizability and causality when interpreting these results.No potential conflict of interest relevant to this article was reported.Okayama University Medical SchoolActa Medica Okayama0386-300X7752023Childcare and Child Development in Japan479490ENAkikoMurataDepartment of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesNaomiMatsumotoFaculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama UniversityChikaraMiyajiDepartment of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesSoshiTakaoFaculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama UniversityTakashiYorifujiFaculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama UniversityOriginal Article10.18926/AMO/65970For decades, the notion has persisted in developed countries that exclusive care by the mothers is best for the development of children up to 3 years of age. To examine the veracity of this “myth of the first three years” in Japan, we examined the effects of childcare facility use for children younger than 3 years on their development using the cohorts of the Longitudinal Survey of Newborns in the 21st Century conducted in Japan. Of the 47,015 respondents to the survey, we studied the children of 5,508 mothers with university/professional education to evaluate the relationships between primary early (< 2.5 years) childcare providers during weekday daytime hours and specific development indices for the ages of 2.5, 5.5, and 8 years. At the age of 2.5 and 5.5 years, children attending childcare facilities were judged as having more advanced developmental behaviors by their parents, such as being able to compose a two-word sentence (adjusted odds ratio [aOR]: 0.22) or to express emotions (aOR: 0.81), compared with those cared for by mothers. However, at the age of 8 years, children who attended childcare facilities as infants < 2.5 years showed more aggressive behavior in interrupting people (aOR: 1.20) and causing disturbances in public (aOR: 1.26) than those cared for by mothers (after adjustment for numerous child and parental factors). Although these results are generally consistent with previous studies, issues potentially involved with problem behavior such as quality of childcare require further investigation, as does the case of children of mothers with more modest educational attainment.No potential conflict of interest relevant to this article was reported.Okayama University Medical SchoolActa Medica Okayama0386-300X7752023Does Participation in the Setouchi Triennale Foster Social Capital? : A Cross-Sectional Study443449ENChikaraMiyajiDepartment of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesSoshiTakaoDepartment of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama UniversityHiroshiHabuDepartment of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesNaomiMatsumotoDepartment of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama UniversityKenAooGraduate School of Humanities and Social Sciences, Okayama UniversityYosukeNishitaGraduate School of Humanities and Social Sciences, Okayama UniversityMasaoTsuriFaculty of Economics, Musashi UniversityTakashiYorifujiDepartment of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama UniversityOriginal Article10.18926/AMO/65966This study examined whether participation in an art project was associated with higher social capital (SC). We conducted a questionnaire survey from November 2021 to March 2022 among residents aged 20 years or older of Naoshima, an island in Kagawa Prefecture, Japan. Before the survey, the Setouchi Triennale had been held on Naoshima four times, starting in 2010. We calculated propensity scores for Triennale participation and performed propensity score matching. We then compared cognitive and structural SC by Triennale participation and found significant differences, respectively. We adopted a conditional ordered logistic regression analysis with propensity score matching for cognitive or structural SC, and found adjusted odd ratios of 2.913 (95%CI, 1.846-4.596) for cognitive SC and 4.535 (95%CI, 2.839-7.244) for structural SC. Our findings suggest that Triennale participation enhanced the cognitive aspect of SC while also building structural SC.No potential conflict of interest relevant to this article was reported.Antiquity PublicationsActa Medica Okayama0003-598X973912022LiDAR survey of the fifth-century Tsukuriyama mounded tomb group in JapanENJunMitsumotoFaculty of Humanities and Social Sciences, Okayama UniversityJosephRyanResearch Institute for the Dynamics of Civilizations, Okayama UniversityYujiYamaguchiResearch Institute for the Dynamics of Civilizations, Okayama UniversityAkiraSeikeFaculty of Humanities and Social Sciences, Okayama UniversityThe authors present the results of a drone-based airborne LiDAR survey of the fifth century AD Tsukuriyama mounded tomb group in Okayama Prefecture, Japan, revealing the relationship between tomb building and the surrounding landscape during Japan's period of ancient state formation.No potential conflict of interest relevant to this article was reported.MDPIActa Medica Okayama1996-107316152023Features and Evolution of Global Energy Trade Patterns from the Perspective of Complex Networks5677ENYingnanCongBusiness School, China University of Political Science and LawYufeiHouBusiness School, China University of Political Science and LawJiamingJiangCenter for Artificial Intelligence and Mathematical Data Science, Okayama UniversityShuangziChenSchool of Economics, Hebei UniversityXiaojingCaiGraduate School of Humanities and Social Sciences, Okayama UniversityAs an integral part of economic trade, energy trade is crucial to international dynamics and national interests. In this study, an international energy trade network is constructed by abstracting countries as nodes and representing energy trade relations as edges. A variety of indicators are designed in terms of networks, nodes, bilaterals, and communities to analyze the temporal and spatial evolution of the global energy trade network from 2001 to 2020. The results indicate that network density and strength have been steadily increasing since the beginning of the 21st century. It is observed that the position of the United States as the core of the international energy market is being impacted by emerging developing countries, thus affecting the existing trade balance based on topological analysis. The weighted analysis of bilateral relations demonstrates that emerging countries such as China, Brazil, and Saudi Arabia are pursuing closer cooperation. The community analysis reveals that an increasing number of countries possess strong energy trade capabilities, resulting in a corresponding increase in energy trade volumes.No potential conflict of interest relevant to this article was reported.Okayama University Medical SchoolActa Medica Okayama0386-300X7742023Association between Radon Hot Spring Bathing and Health Conditions: A Cross-Sectional Study in Misasa, Japan387394ENTakahiroKataokaDepartment of Radiological Technology, Okayama University Graduate School of Health SciencesHiroshiHabuDepartment of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesAyumiTanakaDepartment of Radiological Technology, Okayama University Graduate School of Health SciencesShotaNaoeDepartment of Radiological Technology, Okayama University Graduate School of Health SciencesKaitoMurakamiDepartment of Radiological Technology, Okayama University Graduate School of Health SciencesYukiFujimotoDepartment of Radiological Technology, Okayama University Graduate School of Health SciencesRyoheiYukimineDepartment of Radiological Technology, Okayama University Graduate School of Health SciencesSoshiTakaoDepartment of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesFumihiroMitsunobuDepartment of Longevity and Social Medicine (Geriatrics), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesTakashiYorifujiDepartment of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical SciencesKiyonoriYamaokaDepartment of Radiological Technology, Okayama University Graduate School of Health SciencesOriginal Article10.18926/AMO/65749No epidemiological studies have examined the health effects of daily bathing in radon hot springs.

There is also a Porter-type competitive environment indicator that advocates cluster-like agglomeration. The（modified）specialization coefficient, the Hirshman-Halfindahl index, and the entropy index are examples of indices that directly measure these factors.

The operation does not apply to adjuncts, and thus, adjuncts are unelidable. Funakoshi (J East Asian Linguist 25(2):113–42, 2016), following in the footsteps of Otani and Whitman (Linguist Inquiry 22:345–58, 1991), argues that adjuncts can be elided when V-stranding VP-deletion applies. This article refutes Funakoshi’s proposal. Under rigorous control, adjuncts are generally unelidable even when the context strongly favors the adjunct inclusive interpretation, showing that the language lacks VP-deletion. It is also shown that, for a small number of speakers who permit the adjunct inclusive interpretation, the interpretation is sensitive to island constraints. The observation is attributed to covert right dislocation (Tanaka in J Linguist 37:551–79, 2001), marginally available for such speakers.No potential conflict of interest relevant to this article was

(Research note)10.18926/64200Although it has been said that modern Japanese santoria for Hansen's disease quarantined patients for their entire lives, there were a small number of cases of "arrested discharges" (a "provisional discharge" when progress of the disease was halted) in the 1920s. To examine the reasons why this practice did not spread in Japan, this paper considers the background that led to the admission of patients who were later discharged from the Kyushu Sanatorium (九州療養所) to analyze two types of discharges: "Arrested discharges" and "discharge by relatives." To do so, this paper draws on the "Patient Identification Records"(身分帳) created by the Fifth Ward United Kyushu Sanatorium (now National Sanatorium Kikuchi Keifuen) to manage patients' admission and discharge from the sanatorium. This analysis clarified specific procedures of "arrested discharges" from the facility, which had previously been completely unknown, and it further revealed that regardless if the patients were discharged as an arrested case or by relatives, emphasis was placed upon their prospects for life after discharge, such as the availability of people to support their care and a minimum standard of livingNo potential conflict of interest relevant to this article was reported.ElsevierActa Medica Okayama2352-3409442022The dataset of Japanese patents and patents' holding firms in green vehicle powertrains field108524ENJiamingJiangGraduate School of Humanities and Social Science, Okayama UniversityKensukeBabaCyber-Physical Engineering Informatics Research Core, Okayama UniversityYuZhaoSchool of Management, Department of Management, Tokyo University of ScienceJunshiFengGraduate School of Humanities and Social Science, Okayama UniversitySouKumagaiDepartment of Electrical and Communication Engineering, Faculty of Engineering, Okayama UniversityIn 2020, the Government of Japan declared "2050 carbon neutral" and launched a long-term strategy to create a "virtuous cycle of economy and environment".(1) Japanese firms possess many technologies that contribute to decarbonization, which is important to expand investment for Green Technology (environmental technology) development. As automobiles are major contributors to greenhouse gas emissions [1], the technological shift towards vehicle powertrain systems is an attempt to lower problems like emissions of carbon dioxide, nitrogen oxides [2]. On the other hand, patent data are the most reliable business performance for applied research and development activities when investigating the knowledge domains or the technology evolution (Wand, 1997). Our paper describes a Japanese patents dataset of the vehicle powertrain systems for hybrid electric vehicle (HEV), battery electric vehicle (BEV) and fuel cell electric vehicles (FCEV). In this paper we create a method of bombinating international patent classification (IPC) and keywords to define "green" patents in vehicle powertrains field, using patent data which were applied to Japan Patent Office recorded on EPO's PATSTAT database during 2010 similar to 2019 year. When analyze patents, it is necessary to consider the social situation of each country including language background, we collect patents description documents (abstracts and titles) not only written in English but also in Japanese. Finally, we build a database includes 6025 green patents' description documents and 266 patents' holding firms. With which we then identify 3756 HEV patents, 1716 BEV patents, and 553 FCEV patents. Data about patent holding firms is also appended. The full dataset may be useful to researchers who would like to do further search like natural language processing and machine learning on patent description documents, statistical data analysis for empirical economics.No potential conflict of interest relevant to this article was reported.
