In constructing the new model, we refer to the zoning (ZONE1 to ZONE4) identified by Okamura et al. (2017, Tectonophys.). The construction process consists of the following steps: First, we digitize either unconformities or VP=4 to 5 km/s lines as the seismic basement, whichever is more clearly identifiable. Second, the digitized thickness data of the sedimentary layer from the reflection profiles are geometrically modeled and interpolated to make the three-dimensional structure model. Finally, we supplement the external region of the constructed 3-D sedimentary model using the J-SHIS model provided by the NIED to complete the velocity structure model in the entire Ryukyu arc. The main features of our model are as follows: In ZONE1, off Ishigaki-jima island, the thick sedimentary layer extends about 50 km wide from the Ryukyu trench. In ZONE2, off Miyako-jima island, the thinner layer compared to the other zones is found near the trench, with a thin sedimentary terrace covering the area behind it. In ZONE3, off Okinawa-jima island, the sedimentary layer deepens as it approaches the trench. In ZONE4, off Tokara islands, the deepest layer among all zones is identified. We then conduct 3-D finite-difference simulations of seismic wave propagation using the new and the previous models to confirm the improvement of the new model. In the simulations, the effects of the accretionary prism along the Ryukyu trench on the seismic wave propagation are clearly identified. en-copyright= kn-copyright= en-aut-name=KOMATSUMasanao en-aut-sei=KOMATSU en-aut-mei=Masanao kn-aut-name=小松正直 kn-aut-sei=小松 kn-aut-mei=正直 aut-affil-num=1 ORCID= en-aut-name=URAKAMISohei en-aut-sei=URAKAMI en-aut-mei=Sohei kn-aut-name=浦上想平 kn-aut-sei=浦上 kn-aut-mei=想平 aut-affil-num=2 ORCID= en-aut-name=OKAMOTOTaro en-aut-sei=OKAMOTO en-aut-mei=Taro kn-aut-name=岡元太郎 kn-aut-sei=岡元 kn-aut-mei=太郎 aut-affil-num=3 ORCID= en-aut-name=TAKENAKAHiroshi en-aut-sei=TAKENAKA en-aut-mei=Hiroshi kn-aut-name=竹中博士 kn-aut-sei=竹中 kn-aut-mei=博士 aut-affil-num=4 ORCID= affil-num=1 en-affil=Okayama Gakuin University kn-affil=岡山学院大学 affil-num=2 en-affil=Formerly Department of Earth Sciences, Okayama University kn-affil=元・岡山大学大学院自然科学研究科 affil-num=3 en-affil=Department of Earth and Planetary Sciences, School of Science, Institute of Science Tokyo kn-affil=東京科学大学理学院地球惑星科学系 affil-num=4 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学学術研究院環境生命自然科学学域 en-keyword=Sedimentary layer model kn-keyword=Sedimentary layer model en-keyword=Accretionary prism kn-keyword=Accretionary prism en-keyword=Ryukyu arc kn-keyword=Ryukyu arc END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Title Page en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=56 cd-vols= no-issue=3 article-no= start-page=1 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250321 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Market Segmentation and Market Reactions to Earnings Announcements: A Quarterly Analysis kn-title=市場区分と決算発表に対する市場の反応 ―四半期データを利用した分析― en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this paper is to examine, using quarterly financial data, how the market reaction to earnings announcements in each market segment （prime market segment, standard market segment, and growth market segment） has changed after the revision of market segmentation at the Tokyo Stock Exchange. For the research design, the abnormal volume and residual returns for the 12 quarters around April 1, 2022, when the market segmentation was changed, were calculated using the analysis method of Beaver et al. ［2020］. The results of the analysis suggest that volume is significantly affected by changes in market segmentation. In addition, for the group of stocks in the growth market, there appears to have been some change in the trend of stock price fluctuations after the market segmentation revision. en-copyright= kn-copyright= en-aut-name=NakagawaToyotaka en-aut-sei=Nakagawa en-aut-mei=Toyotaka kn-aut-name=中川豊隆 kn-aut-sei=中川 kn-aut-mei=豊隆 aut-affil-num=1 ORCID= en-aut-name=YamanishiYuki en-aut-sei=Yamanishi en-aut-mei=Yuki kn-aut-name=山西佑季 kn-aut-sei=山西 kn-aut-mei=佑季 aut-affil-num=2 ORCID= en-aut-name=KobayashiHiroaki en-aut-sei=Kobayashi en-aut-mei=Hiroaki kn-aut-name=小林裕明 kn-aut-sei=小林 kn-aut-mei=裕明 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil=熊本県立大学総合管理学部 affil-num=3 en-affil= kn-affil=青山学院大学大学院会計プロフェッション研究科 END start-ver=1.4 cd-journal=joma no-vol=188 cd-vols= no-issue= article-no= start-page=15 end-page=26 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Conceptual Arrangement of Resistance to Change in Organizations: Toward Integrative Understanding from the Perspective of Multidimensional Attitudes kn-title=組織における変化への抵抗の概念整理 ― 多次元的態度の視点からの統合的理解に向けて ― en-subtitle= kn-subtitle= en-abstract= kn-abstract=　VUCA時代と呼ばれる現代社会において，組織には急速に変化する社会環境への柔軟な対応力が求められている。しかし，新たな制度・施策を導入しても組織変革が進まないケースは多い。組織における変化への抵抗は古くから研究されてきた現象であり，変革へのレディネスやコミットメントなどさまざまな概念が提唱されてきた。他方で，これらの概念の内容の重複による混乱が危惧されており，VUCAが注目されはじめた2000 年代以降も，変化への抵抗に関連する新たな概念が提唱されている。こうした混乱を解決し，統合的な理解を図るため，本稿では既往知見をレビューし，社会心理学で伝統的な多次元的態度（認知，感情，行動）の視点から，変化への抵抗とその関連概念を整理した。 en-copyright= kn-copyright= en-aut-name=MISAWARyo en-aut-sei=MISAWA en-aut-mei=Ryo kn-aut-name=三沢良 kn-aut-sei=三沢 kn-aut-mei=良 aut-affil-num=1 ORCID= en-aut-name=ARIYOSHIMie en-aut-sei=ARIYOSHI en-aut-mei=Mie kn-aut-name=有吉美恵 kn-aut-sei=有吉 kn-aut-mei=美恵 aut-affil-num=2 ORCID= en-aut-name=HASEGAWANaoko en-aut-sei=HASEGAWA en-aut-mei=Naoko kn-aut-name=長谷川尚子 kn-aut-sei=長谷川 kn-aut-mei=尚子 aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=2 en-affil=Deparment of Psychology, Kansai University of International Studies kn-affil=関西国際大学心理学部 affil-num=3 en-affil=Faculty of Human Sciences, Department of Psychology, Bunkyo University kn-affil=文教大学人間科学部心理学科 en-keyword=組織変革 kn-keyword=組織変革 en-keyword=変化への抵抗 kn-keyword=変化への抵抗 en-keyword=多次元的態度 kn-keyword=多次元的態度 en-keyword=文献レビュー kn-keyword=文献レビュー END start-ver=1.4 cd-journal=joma no-vol=60 cd-vols= no-issue= article-no= start-page=104813 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Petrological characterization for material provenance of haniwa earthenware from mounded tombs in the Kibi region, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=To determine the provenance of the materials used in the production of haniwa earthenware unearthed from mounded tombs (kofun) in the Kibi region (modern Okayama Prefecture) during the Kofun period (late 3rd ? 6th century CE) of Japan, we carried out petrological analyses of haniwa sherds, including optical microscopy, X-ray diffractometry, X-ray fluorescence spectroscopy, and electron-probe analysis. The 25 haniwa sherds analyzed from 12 representative mounded tombs are composed of mineral and rock inclusions with variable grain size set in a clay matrix. The dominant inclusions are quartz, K-feldspar, and plagioclase, associated with minor amounts of amphibole, volcanic glass, and granitic rocks in all the haniwa sherds, and small amounts of hornfels, quartz rock, and accessory minerals, including mica, ilmenite, and chromite, in some of the sherds. Amphibole and plagioclase have compositional variations indicative of the mixing of tephra and granitic components. The compositions of volcanic glass inclusions are similar to those of the Aira-Tanzawa and Kikai-Akahoya tephras widely distributed in southwestern Japan. Bulk chemical compositions show magmatic differentiation trends, which are variable between individual tombs. From these results, it is concluded that the paste materials of haniwa in the Kibi region were commonly derived from weathered granitic rocks mixed with minor amounts of three widespread tephras. The variations of chemical and mineralogical compositions are probably the reflection of local geologic settings, suggesting the presence of specific mining sites of paste materials around each tomb. The mining sites could be located at the bases of hills of granitic rocks covered by widespread tephras and in some cases, near the flood plain of big river systems. en-copyright= kn-copyright= en-aut-name=NozakaToshio en-aut-sei=Nozaka en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhbayashiNaoya en-aut-sei=Ohbayashi en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TodaYuki en-aut-sei=Toda en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugiuraKanako en-aut-sei=Sugiura en-aut-mei=Kanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NozakiTakahiro en-aut-sei=Nozaki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KimuraOsamu en-aut-sei=Kimura en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoNaoko en-aut-sei=Matsumoto en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SeikeAkira en-aut-sei=Seike en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Earth Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Archaeology, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for the Dynamics of Civilizations, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for the Dynamics of Civilizations, Okayama University kn-affil= affil-num=7 en-affil=Research Institute for the Dynamics of Civilizations, Okayama University kn-affil= affil-num=8 en-affil=Department of Archaeology, Okayama University kn-affil= en-keyword=Haniwa kn-keyword=Haniwa en-keyword=Paste material kn-keyword=Paste material en-keyword=Provenance kn-keyword=Provenance en-keyword=Kofun kn-keyword=Kofun en-keyword=Kibi kn-keyword=Kibi en-keyword=Japan kn-keyword=Japan END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=裏表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学地球科学研究報告 投稿規定（約款） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=1 article-no= start-page=21 end-page=35 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A new insight into the driving mechanism for plate tectonics?the relationship between tectonic processes and the circumferential tensile forces associated with a rotating planet? en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Mantle convection currents are the currently accepted driving force for plate tectonics that have ripped apart the continents and created oceans. Because of these actions, continental collisions and ocean closures have resulted. Our paper challenges the conventional concept and provides an alternate, mathematically justified drive mechanism. The pull-push motions of such convection currents in the upper mantle are here concluded to be too weak to be the driving mechanism.
　Our proposal for such global scale forces concerns the effect of an offset centre of mass of the Earth that results in rotational wobbling. Kepler’s laws of planetary motion demonstrate the rotational behavior of the Earth to be aligned with the Sun on the outward and inward motions of the elliptical orbit. The unbalanced rotation on a fixed gravitational axis results in circumferential stresses on the outer Earth’s rim that is more than strong enough to pull the continental plates apart. The proposed unbalanced rotational stress force equation is shown to be sufficient to drive the cyclic breakup and reassembly of the continental plates, as well as the generation of new oceanic crust and subduction zones. Mantle convection currents are here demonstrated to have a passive rather than active role in the plate movements. en-copyright= kn-copyright= en-aut-name=MAURERRobert en-aut-sei=MAURER en-aut-mei=Robert kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HARKERStuart en-aut-sei=HARKER en-aut-mei=Stuart kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SUZUKIShigeyuki en-aut-sei=SUZUKI en-aut-mei=Shigeyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WHEELERAllan en-aut-sei=WHEELER en-aut-mei=Allan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Maurer Associates C/o Wellhead Metering Systems affil-num=2 en-affil= kn-affil=Morningside Petroleum Geology Consultancy Ltd. affil-num=3 en-affil= kn-affil=Department of Earth Sciences, Okayama University affil-num=4 en-affil= kn-affil=Professional editor of publications en-keyword=Differential circumferential tensile force kn-keyword=Differential circumferential tensile force en-keyword=Rotating Earth kn-keyword=Rotating Earth en-keyword=Offset centre of mass kn-keyword=Offset centre of mass en-keyword=radius of eccentricity kn-keyword=radius of eccentricity END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=1 article-no= start-page=13 end-page=20 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Microtremor exploration in Tsushima Campus, Okayama University kn-title=岡山大学津島キャンパスおける微動探査 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　In this report, microtremor array observations were conducted in the Tsushima Campus of Okayama University, and the subsurface velocity structure was estimated from the analysis of the records. The results indicate that a five-layer S-wave velocity structure from the surface to the seismic basement equivalent layer with thicknesses of 8, 24, 80 and 180 m and velocities of 150, 450, 1100, 1700 and 3200 m/s, respectively, is reasonable. This model explains to some extent the observed phase velocity and H/V spectral ratios. It is also consistent with the surface borehole results. Furthermore, the areal characteristics of the H/V spectral ratios were also presented, allowing us to estimate the trend of the ground structure in shallow areas. en-copyright= kn-copyright= en-aut-name=YAMADANobuyuki en-aut-sei=YAMADA en-aut-mei=Nobuyuki kn-aut-name=山田伸之 kn-aut-sei=山田 kn-aut-mei=伸之 aut-affil-num=1 ORCID= en-aut-name=TAKENAKAHiroshi en-aut-sei=TAKENAKA en-aut-mei=Hiroshi kn-aut-name=竹中博士 kn-aut-sei=竹中 kn-aut-mei=博士 aut-affil-num=2 ORCID= affil-num=1 en-affil=Faculty of Science and Technology, Kochi University kn-affil=高知大学理工学部地球環境防災学科 affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学学術研究院環境生命自然科学学域 en-keyword=Okayama kn-keyword=Okayama en-keyword=Microtremor array exploration kn-keyword=Microtremor array exploration en-keyword=S-wave velocity kn-keyword=S-wave velocity en-keyword=H/V spectral ratio kn-keyword=H/V spectral ratio END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=1 article-no= start-page=1 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Petrological characteristics of the stone chamber of Tobiotsuka Kofun, Okayama Prefecture kn-title=鳶尾塚古墳の石室石材の岩石学的特徴 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Tobiotsuka Kofun, a tumulus built on the Misu Hills in the Kofun period, has a horizontal stone chamber made of huge stone blocks with a width up to 2 meters or more. To specify the source of the stone blocks, we carried out the measurement of magnetic susceptibility, petrographic observation, and chemical analysis of minerals. The stones are amphibole-biotite granite with phenocrystic large grains of K-feldspar. The back-wall stone of the chamber has higher magnetic susceptibility than ceiling and side-wall stones, which probably results from a higher amount of magnetite formed by the alteration of biotite in the back-wall stone. Furthermore, the back-wall stone is different from ceiling stone in that it has lower XMg [Mg/(Mg + Fe) mole ratio], lower Al, Ti, and Na + K contents and higher Si contents of amphibole, higher XMg of biotite, and shows a tendency to have higher Na (albite component) contents at rims of plagioclase crystals and lower Ti contents of zircon. These characteristics of the back-wall stone are similar to those of granite exposed in the Koshinzan area about 2 km northeast of Tobiotsuka Kofun, whereas the ceiling and side-wall stones are similar to granite outcrops in the vicinity of Tobiotsuka Kofun, e.g., in the Midoriyama area. It is concluded that the quarry for the back-wall was located at a different place from that for the ceiling and side-wall stones. en-copyright= kn-copyright= en-aut-name=KANEKOTakahiro

年北海道胆振東部地震の初期の破壊過程 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The rupture process at the beginning stage of the 2018 Hokkaido Eastern Iburi, Japan, earthquake (MJ 6.7) is investigated by analyzing P-wave records from local strong-motion stations. The records show about 3 s of small amplitude arrival (so-called "initial rupture phase") followed by the onset of the main energy release ("main rupture phase"). In this paper we address the issue: where the seismic energy release corresponding to the main rupture phase started at the primary stage of the main rupture, by locating the main rupture onset position. For this aim we applied the 2D and the 3D search methods to estimate the relative location of the onset of the main rupture with respect to the hypocenter, and the time difference between them. The 2D method assumes a plausible initial fault plane and locates the main rupture onset position on the initial fault plane, while the 3D method does not require such assumed fault planes. In the 2D method we employed each of the nodal planes of the first-motion focal mechanism as the initial rupture plane. The 3D method was able to give a better solution than the 2D one. It suggests that the main rupture initiation point might not be on the same fault plane as the hypocenter is. The solution shows that the main rupture onset point is 5.8 km southward and 2.5 km upward from the hypocenter, with the rupture time of 3.3 s from the origin time. It is consistent with the previous studies on the relationship between the magnitude and the initial rupture duration. en-copyright= kn-copyright= en-aut-name=KOWARIHirofumi en-aut-sei=KOWARI en-aut-mei=Hirofumi kn-aut-name=小割啓史 kn-aut-sei=小割 kn-aut-mei=啓史 aut-affil-num=1 ORCID= en-aut-name=KOMATSUMasanao en-aut-sei=KOMATSU en-aut-mei=Masanao kn-aut-name=小松正直 kn-aut-sei=小松 kn-aut-mei=正直 aut-affil-num=2 ORCID= en-aut-name=TAKENAKAHiroshi en-aut-sei=TAKENAKA en-aut-mei=Hiroshi kn-aut-name=竹中博士 kn-aut-sei=竹中 kn-aut-mei=博士 aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学学術研究院自然科学学域 en-keyword=2018 Hokkaido Eastern Iburi earthquake kn-keyword=2018 Hokkaido Eastern Iburi earthquake en-keyword=fault plane kn-keyword=fault plane en-keyword=initial rupture kn-keyword=initial rupture en-keyword=strong motion kn-keyword=strong motion END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=1 article-no= start-page=29 end-page=48 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Summary of our activities toward development of the ESD interdisciplinary study plans on climate and cultural understanding education with attention to the seasonal cycle and “seasonal feeling” around Japan and Europe kn-title=気候・文化理解教育の学際的ESD学習プラン開発へ向けた取り組み（日本とヨーロッパの季節サイクルや季節感に注目して） en-subtitle= kn-subtitle= en-abstract= kn-abstract=We have continued the interdisciplinary integration of the knowledge on climate and music and have developed the crosscutting study plans on the climate and cultural understanding education.

The gravel of the Kayo Formation occupied paleo-valley of Pre-Paleogene basement. The Yagane and Ukan formations unconformably overlay Pre-Paleogene rocks and occupy the gentle valley on the Kibi Surface as valley fill deposits.
The fluvial of the Kayo Formation is mainly composed of conglomerate with minor amount of sandstone and mudstone. The fluvial Yagane Formation is mainly composed of conglomerate and associated with sandstone, mudstone and coal beds. The marine Ukan Formation is subdivided into 3 members, the Yamagata Muddy sandstone Member (YMM), the Shimoyokomi Sandstone Member (SSM) and the Tsuneyama Mudstone Member (TMM) in ascending order. The YMM is characterized by the bio-disturbed very poorly sorted muddy sandstone with frequent burrows, which indicate tidal flat deposits. The SSM is mainly composed of parallel bedded well-sorted sandstone with occasional burrows, which suggest near shore deposits. The TMM is composed of homogeneous clay rich mudstone, which implies off shore deposits.
The boundary between the SSM and TMM (the contact of the sandstone and mudstone) is distinctive and correlative throughout the study area. The boundary is considered to be formed under similar water depth. The variations of the boundary height indicate a later ground movement. From the north to the south in about 25km distance, the height of the boundary changes 260m (in Ukan), 300m (in Takeshou), 360m (in Kibikogentoshi) and 260m (in Nichiouji). It indicates that a very gentle upwarping of the Kibi Plateau Surface was formed after the deposition of the Miocene. en-copyright= kn-copyright= en-aut-name=TANAKAHajime en-aut-sei=TANAKA en-aut-mei=Hajime kn-aut-name=田中元 kn-aut-sei=田中 kn-aut-mei=元 aut-affil-num=1 ORCID= en-aut-name=SUZUKIShigeyuki en-aut-sei=SUZUKI en-aut-mei=Shigeyuki kn-aut-name=鈴木茂之 kn-aut-sei=鈴木 kn-aut-mei=茂之 aut-affil-num=2 ORCID= affil-num=1 en-affil=Seibu Engineering Consultants Co., Ltd. kn-affil=西部技術コンサルタント株式会社 affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学理学部地球科学科 en-keyword=Kibi Plateau Surface kn-keyword=Kibi Plateau Surface en-keyword=Upwarping kn-keyword=Upwarping en-keyword=Miocene kn-keyword=Miocene en-keyword=Ukan Formation kn-keyword=Ukan Formation END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Title Page en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue=1 article-no= start-page=53 end-page=63 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230118 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fbxl4 Regulates the Photic Entrainment of Circadian Locomotor Rhythms in the Cricket Gryllus bimaculatus en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photic entrainment is an essential property of the circadian clock that sets the appropriate timing of daily behavioral and physiological events. However, the molecular mechanisms underlying the entrainment remain largely unknown. In the cricket Gryllus bimaculatus, the immediate early gene c-fosB plays an important role in photic entrainment, followed by a mechanism involving cryptochromes (crys). However, the association between c-fosB expression and crys remains unclear. In the present study, using RNA-sequencing analysis, we found that five Fbxl family genes (Fbxl4, Fbxl5, Fbxl16, Fbxl-like1, and Fbxl-like2) encoding F-box and leucine-rich repeat proteins are likely involved in the mechanism following light-dependent c-fosB induction. RNA interference (RNAi) of c-fosA/B significantly downregulated Fbxls expression, whereas RNAi of the Fbxl genes exerted no effect on c-fosB expression. The Fbxl genes showed rhythmic expression under light-dark cycles (LDs) with higher expression levels in early day (Fbxl16), whole day (Fbxl-like1), or day-to-early night (Fbxl4, Fbxl5, and Fbxl-like2), whereas their expression was reduced in the dark. We then examined the effect of their RNAi on the photic entrainment of the locomotor rhythm and found that RNAi of Fbxl4 either disrupted or significantly delayed the re-entrainment of the locomotor rhythm to shifted LDs. These results suggest that light-induced c-fosB expression stimulates Fbxl4 expression to reset the circadian clock. en-copyright= kn-copyright= en-aut-name=TakeuchiKazuki en-aut-sei=Takeuchi en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsukaMirai en-aut-sei=Matsuka en-aut-mei=Mirai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShinoharaTsugumichi en-aut-sei=Shinohara en-aut-mei=Tsugumichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HamadaMayuko en-aut-sei=Hamada en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TomiyamaYasuaki en-aut-sei=Tomiyama en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TomiokaKenji en-aut-sei=Tomioka en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University, Okayama 700-8530, Japan kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=54 cd-vols= no-issue=1 article-no= start-page=1 end-page=12 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220729 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Preliminary Study of the Relationship Between Accounting Fundamentals and Stock Prices for the Prime Market kn-title=プライム市場を対象とした会計のファンダメンタルズと株価の関係に関する予備的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this paper is to examine the relationship between accounting fundamentals and future abnormal returns for prime market issues on the Tokyo Stock Exchange.

To elaborate, the market classification on the Tokyo Stock Exchange has been reorganized from the four categories of“ First Section,”“ Second Section,”“ Mothers,” and“ JASDAQ” to three categories of“ Prime Market,”“ Standard Market,” and“ Growth Market.” By examining the relationship between accounting fundamentals and future abnormal returns for prime market stocks, this paper provides empirical evidence on how the introduction of this new market classification affects the relationship between value based on accounting fundamentals and stock prices. en-copyright= kn-copyright= en-aut-name=NakagawaToyotaka en-aut-sei=Nakagawa en-aut-mei=Toyotaka kn-aut-name=中川豊隆 kn-aut-sei=中川 kn-aut-mei=豊隆 aut-affil-num=1 ORCID= en-aut-name=YamanishiYuki en-aut-sei=Yamanishi en-aut-mei=Yuki kn-aut-name=山西佑季 kn-aut-sei=山西 kn-aut-mei=佑季 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil=熊本県立大学総合管理学部准教授 END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=裏表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学地球科学研究報告 投稿規定（約款） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=1 article-no= start-page=27 end-page=103 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=FDM simulation of long-period ground motions around Oita Prefecture, Japan, using a land-ocean unified 3D structure model kn-title=地形を考慮した陸海統合3次元地震波速度構造モデルを用いた大分県周辺の長周期地震動シミュレーション en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oita prefecture is located in northeastern part of Kyushu Island which is characterized by active subduction of the Philippine Sea plate (PHS) beneath the Eurasian plate and several active volcanoes along with the volcanic front. Oita area has frequently been damaged by large earthquakes and tsunamis since ancient times. From the point of view of disaster prevention, it is important to investigate the feasibility of strong ground motion prediction using realistic structural models. In this paper we use a land-ocean unified 3D (three-dimensional) structure model around Oita prefecture, which includes land and sea-floor topography and a seawater layer as well as subsurface structures of the arc side and the PHS slab to conduct the FDM (finite-difference method) simulations of strong ground motion in land and ocean areas for the 2015 Southern Oita, Japan, earthquake (MJMA5.7) whose hypocenter is located in the PHS slab. The simulated long-period (2?20 s) ground motions reproducing observed records demonstrate substantial contributions of thick low-velocity sediment layers in and around Beppu Bay and Oita basin to development of the motions. We also examine the topographic effects on the seismic motion by analyzing the simulation results to show the strong enhancement of the later phases. en-copyright= kn-copyright= en-aut-name=OkunakaTatsuya en-aut-sei=Okunaka en-aut-mei=Tatsuya kn-aut-name=奥仲達也 kn-aut-sei=奥仲 kn-aut-mei=達也 aut-affil-num=1 ORCID= en-aut-name=KomatsuMasanao en-aut-sei=Komatsu en-aut-mei=Masanao kn-aut-name=小松正直 kn-aut-sei=小松 kn-aut-mei=正直 aut-affil-num=2 ORCID= en-aut-name=TakenakaHiroshi en-aut-sei=Takenaka en-aut-mei=Hiroshi kn-aut-name=竹中博士 kn-aut-sei=竹中 kn-aut-mei=博士 aut-affil-num=3 ORCID= en-aut-name=YoshimiMasayuki en-aut-sei=Yoshimi en-aut-mei=Masayuki kn-aut-name=吉見雅行 kn-aut-sei=吉見 kn-aut-mei=雅行 aut-affil-num=4 ORCID= en-aut-name=NakamuraTakeshi en-aut-sei=Nakamura en-aut-mei=Takeshi kn-aut-name=中村武史 kn-aut-sei=中村 kn-aut-mei=武史 aut-affil-num=5 ORCID= en-aut-name=OkamotoTaro en-aut-sei=Okamoto en-aut-mei=Taro kn-aut-name=岡元太郎 kn-aut-sei=岡元 kn-aut-mei=太郎 aut-affil-num=6 ORCID= affil-num=1 en-affil=Formerly Department of Earth Sciences, Okayama University kn-affil=元・岡山大学理学部地球科学科 affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学学術研究院自然科学学域 affil-num=4 en-affil=Geological Survey of Japan, National Institute of Advanced Industrial Science and Technology kn-affil=国立研究開発法人産業技術総合研究所 活断層・火山研究部門 affil-num=5 en-affil=Formerly Japan Agency for Marine-Earth Science and Technology kn-affil=元・国立研究開発法人海洋研究開発機構 affil-num=6 en-affil=Department of Earth and Planetary Sciences, School of Science, Tokyo Institute of Technology kn-affil=東京工業大学理学院地球惑星科学系 en-keyword=strong motion kn-keyword=strong motion en-keyword=Oita kn-keyword=Oita en-keyword=the 2015 Southern Oita earthquake kn-keyword=the 2015 Southern Oita earthquake en-keyword=long-period ground motion kn-keyword=long-period ground motion en-keyword=simulation kn-keyword=simulation en-keyword=finite-difference method kn-keyword=finite-difference method en-keyword=topography kn-keyword=topography END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=1 article-no= start-page=1 end-page=25 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Depositional history of the Paleogene to Neogene valley fill deposits and topographic change in the Kibi Plateau region, Okayama City, Southwest Japan kn-title=岡山市北部吉備高原地域に分布する古第三系・新第三系の分布・堆積相と古地理変遷 en-subtitle= kn-subtitle= en-abstract=The deposition of the Paleogene to Neogene sediments in the Kibi Plateau region played an important role to form the Kibi Plateau Surface. Study area is situated in the southern part of the Kibi Plateau. Field work has been continued more than 30 years and traced distribution of the deposits which make clear the paleo-topography. Sedimentary facies of deposits were observed to understand depositional environments. Without Fission-Track zircon dating from tuff samples, we could not divide and define the formations. The Paleogene Kibi Group and the latest Paleogene to Neogene Bihoku Group are distributed in the study area. The Kibi Group is unusual deposits which filled steep valley in mountain area and comprise the Tomiyoshi Formation (36 to 34 Ma) and the Tsudaka Formation (29 to 27 Ma). The formations are fluvial deposits and have similar litho-facies. The distribution of the formations indicate drainage system when deposited. Conglomerates with imbricate structure are the major component of the formations and sandstones and mudstones (sometimes with plant fragments and rootlets) are associated. The Bihoku Group is composed of the fluvial Yagane Formation (24.5 to 25.5 Ma) and the shallow marine Nichiouji Formation (15 to 16 Ma). The formations have the same depositional basin of low relief valley. The Yagane Formation is composed of conglomerate, sandstone, mudstone and coaly mudstone. The Nichiouji Formation is composed of well sorted sandstone with marine fossils. kn-abstract= en-copyright= kn-copyright= en-aut-name=TanakaHajime en-aut-sei=Tanaka en-aut-mei=Hajime kn-aut-name=田中元 kn-aut-sei=田中 kn-aut-mei=元 aut-affil-num=1 ORCID= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name=鈴木茂之 kn-aut-sei=鈴木 kn-aut-mei=茂之 aut-affil-num=2 ORCID= affil-num=1 en-affil=Seibu Engineering Consultants Co., Ltd. kn-affil=西部技術コンサルタント株式会社 affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学 特命教授・名誉教授 en-keyword=Kibi Plateau Surface kn-keyword=Kibi Plateau Surface en-keyword=Paleogene kn-keyword=Paleogene en-keyword=Kibi Group kn-keyword=Kibi Group en-keyword=Miocene kn-keyword=Miocene en-keyword=Bihoku Group kn-keyword=Bihoku Group END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Title Page en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=9 article-no= start-page=eabk0331 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202234 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Vasopressin-oxytocin?type signaling is ancient and has a conserved water homeostasis role in euryhaline marine planarians en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vasopressin/oxytocin (VP/OT)?related peptides are essential for mammalian antidiuresis, sociosexual behavior, and reproduction. However, the evolutionary origin of this peptide system is still uncertain. Here, we identify orthologous genes to those for VP/OT in Platyhelminthes, intertidal planarians that have a simple bilaterian body structure but lack a coelom and body-fluid circulatory system. We report a comprehensive characterization of the neuropeptide derived from this VP/OT-type gene, identifying its functional receptor, and name it the “platytocin” system. Our experiments with these euryhaline planarians, living where environmental salinities fluctuate due to evaporation and rainfall, suggest that platytocin functions as an “antidiuretic hormone” and also organizes diverse actions including reproduction and chemosensory-associated behavior. We propose that bilaterians acquired physiological adaptations to amphibious lives by such regulation of the body fluids. This neuropeptide-secreting system clearly became indispensable for life even without the development of a vascular circulatory system or relevant synapses. en-copyright= kn-copyright= en-aut-name=KobayashiAoshi en-aut-sei=Kobayashi en-aut-mei=Aoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HamadaMayuko en-aut-sei=Hamada en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshidaMasa-aki en-aut-sei=Yoshida en-aut-mei=Masa-aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KobayashiYasuhisa en-aut-sei=Kobayashi en-aut-mei=Yasuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsutsuiNaoaki en-aut-sei=Tsutsui en-aut-mei=Naoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SekiguchiToshio en-aut-sei=Sekiguchi en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsukawaYuta en-aut-sei=Matsukawa en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MaejimaSho en-aut-sei=Maejima en-aut-mei=Sho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=GingellJoseph J. en-aut-sei=Gingell en-aut-mei=Joseph J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SekiguchiShoko en-aut-sei=Sekiguchi en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HamamotoAyumu en-aut-sei=Hamamoto en-aut-mei=Ayumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HayDebbie L. en-aut-sei=Hay en-aut-mei=Debbie L. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MorrisJohn F. en-aut-sei=Morris en-aut-mei=John F. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SakamotoTatsuya en-aut-sei=Sakamoto en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=SakamotoHirotaka en-aut-sei=Sakamoto en-aut-mei=Hirotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Oki Marine Biological Station, Shimane University kn-affil= affil-num=4 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=5 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=6 en-affil=Noto Marine Laboratory, Institute of Nature and Environmental Technology, Division of Marine Environmental Studies, Kanazawa University kn-affil= affil-num=7 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Vertex Pharmaceuticals (Europe) Ltd. kn-affil= affil-num=10 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=11 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=12 en-affil=School of Biological Sciences and Maurice Wilkins Centre for Molecular Biodiscovery, University of Auckland kn-affil= affil-num=13 en-affil=Department of Physiology, Anatomy, and Genetic, Le Gros Clark Building, University of Oxford kn-affil= affil-num=14 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=15 en-affil=Ushimado Marine Institute (UMI), Graduate School of Natural Science and Technology, Okayama University, Ushimado kn-affil= END start-ver=1.4 cd-journal=joma no-vol=39 cd-vols= no-issue=1 article-no= start-page=157 end-page=165 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220128 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Observing Phylum-Level Metazoan Diversity by Environmental DNA Analysis at the Ushimado Area in the Seto Inland Sea en-subtitle= kn-subtitle= en-abstract= kn-abstract=The dynamics of microscopic marine plankton in coastal areas is a fundamental theme in marine biodiversity research, but studies have been limited because the only available methodology was collection of plankton using plankton-nets and microscopic observation. In recent years, environmental DNA (eDNA) analysis has exhibited potential for conducting comprehensive surveys of marine plankton diversity in water at fixed points and depths in the ocean. However, few studies have examined how eDNA analysis reflects the actual distribution and dynamics of organisms in the field, and further investigation is needed to determine whether it can detect distinct differences in plankton density in the field. To address this, we analyzed eDNA in seawater samples collected at 1 km intervals at three depths over a linear distance of approximately 3.0 km in the Seto Inland Sea. The survey area included a location with a high density of Acoela (Praesagittifera naikaiensis). However, the eDNA signal for this was little to none, and its presence would not have been noticed if we did not have this information beforehand. Meanwhile, eDNA analysis enabled us to confirm the presence of a species of Placozoa that was previously undiscovered in the area. In summary, our results suggest that the number of sequence reads generated from eDNA samples in our project was not sufficient to predict the density of a particular species. However, eDNA can be useful for detecting organisms that have been overlooked using other methods. en-copyright= kn-copyright= en-aut-name=KawashimaTakeshi en-aut-sei=Kawashima en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshidaMasa-aki en-aut-sei=Yoshida en-aut-mei=Masa-aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyazawaHideyuki en-aut-sei=Miyazawa en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakanoHiroaki en-aut-sei=Nakano en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakanoNatumi en-aut-sei=Nakano en-aut-mei=Natumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakamotoTatsuya en-aut-sei=Sakamoto en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HamadaMayuko en-aut-sei=Hamada en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=National Institute of Genetics kn-affil= affil-num=2 en-affil=Marine Biological Science Section, Education and Research Center Biological Resources, Faculty of Life and Environmental Science, Shimane University kn-affil= affil-num=3 en-affil=National Institute of Genetics kn-affil= affil-num=4 en-affil=Shimoda Marine Research Center, University of Tsukuba kn-affil= affil-num=5 en-affil=Department of Biology, Nara Medical University kn-affil= affil-num=6 en-affil=Ushimado Marine Institute, Okayama University kn-affil= affil-num=7 en-affil=Ushimado Marine Institute, Okayama University kn-affil= en-keyword=eDNA kn-keyword=eDNA en-keyword=marine invertebrate kn-keyword=marine invertebrate en-keyword=Xenacoelomorpha kn-keyword=Xenacoelomorpha en-keyword=Acoela kn-keyword=Acoela en-keyword=Praesagittifera naikaiensis kn-keyword=Praesagittifera naikaiensis en-keyword=Placozoa kn-keyword=Placozoa en-keyword=Trichoplax adhaerens kn-keyword=Trichoplax adhaerens END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=裏表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学地球科学研究報告 投稿規定（約款） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=1 article-no= start-page=39 end-page=50 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Estimation of displacement waveforms by baseline correction of near-fault acceleration records of the 2016 Kumamoto earthquake with median filter kn-title=メジアンフィルターを用いた2016年熊本地震の断層近傍における加速度記録の基線補正と変位波形の推定 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The 2016 Kumamoto earthquake sequence occurred on April 14 (MJMA 6.5) and April 16 (MJMA 7.3). Seismic intensity of 7 on the Japan Meteorological Agency (JMA) scale was observed in Mashiki Town, Kumamoto Prefecture for the both events and in Nishihara Village, Kumamoto Prefecture for the April-16 event. We estimate the displacement waveforms from these acceleration records. Since the acceleration seismograms include the long-period noise due to tilting of the ground and instrumental effects, the baseline corrections are required to derive the accurate velocity and displacement waveforms. We apply a median filter to the velocity waveforms to identify the linear trends on them due to the steplike noise on the acceleration records, and determine the time at which baseline shifts take place and the step value of each shift for the baseline correction through trial and error. Our baseline correction can successfully reconstruct the velocity and displacement waveforms from the acceleration records. The displacement waveforms show the static components consistent with the geodetic data. en-copyright= kn-copyright= en-aut-name=WatanabeTomotsugu en-aut-sei=Watanabe en-aut-mei=Tomotsugu kn-aut-name=渡邉禎貢 kn-aut-sei=渡邉 kn-aut-mei=禎貢 aut-affil-num=1 ORCID= en-aut-name=KomatsuMasanao en-aut-sei=Komatsu en-aut-mei=Masanao kn-aut-name=小松正直 kn-aut-sei=小松 kn-aut-mei=正直 aut-affil-num=2 ORCID= en-aut-name=TakenakaHiroshi en-aut-sei=Takenaka en-aut-mei=Hiroshi kn-aut-name=竹中博士 kn-aut-sei=竹中 kn-aut-mei=博士 aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 en-keyword=2016 Kumamoto earthquake kn-keyword=2016 Kumamoto earthquake en-keyword=baseline correction kn-keyword=baseline correction en-keyword=median filter kn-keyword=median filter en-keyword=displacement kn-keyword=displacement END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=1 article-no= start-page=29 end-page=38 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Synthetic nearfield seismograms at a subsurface position in a horizontally layered half-space kn-title=水平成層構造における地中の近地理論地震記象 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We extend the computational code of Takenaka and Sasatani (2000) for synthetic nearfield seismograms for horizontally layered elastic media, based on the reflection/transmission matrices and the discrete wavenumber summation method, to calculate seismic motion and its spatial derivatives at a subsurface position in the attenuative media.

These Paleogene and Miocene units are valley fill deposits. The Kibi Group is composed of formations which is deposited by more than 7 different depositional events during earliest to latest Paleogene Period. Repeated cycles of “erosion - formation of new valley system - deposition and fill up the valley” created the low relief topographic surface. The deposition of the Miocene deposits might complete the Kibi Plateau Surface. Detailed field works have done in middle western part of Okayama Prefecture. The Kibi Plateau Surface in study area is gently dipping from NW (about 600m high) to SE (about 100m high). The distributions of the Paleogene and Miocene deposits fit the surface. At the southern margin of the Kibi Plateau, the surface is a little inclined (from 400m high to 100m high) where the bottom of paleo-valleys of the Paleogene deposits are subparallel to the surface. It suggests that the gentle tilting of the Kibi Plateau is caused by an up-warping. en-copyright= kn-copyright= en-aut-name=TanakaHajime en-aut-sei=Tanaka en-aut-mei=Hajime kn-aut-name=田中元 kn-aut-sei=田中 kn-aut-mei=元 aut-affil-num=1 ORCID= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name=鈴木茂之 kn-aut-sei=鈴木 kn-aut-mei=茂之 aut-affil-num=2 ORCID= affil-num=1 en-affil=Fukken Co., Ltd., Okayama branch office kn-affil=復建調査設計株式会社岡山支社 affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 en-keyword=Kibi Plateau Surface kn-keyword=Kibi Plateau Surface en-keyword=Paleogene kn-keyword=Paleogene en-keyword=Neogene kn-keyword=Neogene en-keyword=Miocene kn-keyword=Miocene END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=1 article-no= start-page=1 end-page=17 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=For development of an ESD-based teacher training program on climate change : overlooking geo-phenomena on various timescales kn-title=気候変動に関するESD教師教育開発へ向けて：様々な時間スケールの地学現象の俯瞰 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Since the recent climate change is an important topic in the context of SDGs (Sustainable Development Goals) and ESD (Education for Sustainable Development), teacher training course should produce educators with sufficient geo-literacy. In order to meet this requirement, the authors have designed a study plan that facilitates students’ better understanding of current climate change issues, which will be offered in a lecture at university by two speakers who have different specialties, paleoenvironmental science and meteorology. Summary of the lecture is as follows. At first, from the branch of paleoenvironmental science, a major cooling event at the Eocene/Oligocene boundary and the glacial-interglacial cycles in the Quaternary will be explained. We will then instruct the participants to compare these climatic events with recent global warming, in order to remind them of the extraordinary higher speed of the recent climate change than climatic events in the geological past. Followed by these global topics, climatological features in East Asia including Japan (e.g. regional/seasonal difference in climate and year-to-year variations) will be demonstrated in order to relate local issues to global ones. By these efforts, the lecture aims to cultivate students’ ability to grasp geophenomena from various aspects and understand the true nature of problems, which may contribute producing educators who can execute ESD programs. en-copyright= kn-copyright= en-aut-name=KatoYuji en-aut-sei=Kato en-aut-mei=Yuji kn-aut-name=加藤悠爾 kn-aut-sei=加藤 kn-aut-mei=悠爾 aut-affil-num=1 ORCID= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=2 ORCID= affil-num=1 en-affil=Center for Advanced Marine Core Research, Kochi University kn-affil=高知大学 海洋コア総合研究センター affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 en-keyword=time scales kn-keyword=time scales en-keyword=geologic events kn-keyword=geologic events en-keyword=paleoenvironmental science kn-keyword=paleoenvironmental science en-keyword=meteorology and climatology kn-keyword=meteorology and climatology en-keyword=global warming kn-keyword=global warming en-keyword=ESD kn-keyword=ESD en-keyword=SDGs kn-keyword=SDGs END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Title Page en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=50 cd-vols= no-issue= article-no= start-page=233 end-page=239 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210127 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Interrelations among Basic Psychological Needs Satisfaction in Part-time Employment: A Study of International Students in Japan kn-title=アルバイト活動における基本的心理欲求充足間の関係 : 在日外国人留学生を対象とした検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YanLin en-aut-sei=Yan en-aut-mei=Lin kn-aut-name=閻琳 kn-aut-sei=閻 kn-aut-mei=琳 aut-affil-num=1 ORCID= en-aut-name=HoriuchiTakashi en-aut-sei=Horiuchi en-aut-mei=Takashi kn-aut-name=堀内孝 kn-aut-sei=堀内 kn-aut-mei=孝 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=立命館大学総合心理学部 affil-num=2 en-affil= kn-affil=岡山大学大学院社会文化科学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year= dt-pub= dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Erodium moschatum (L.)

The large climatological difference of precipitation at Kochi from that at Okayama throughout the warm season was greatly contributed to by the days with the precipitation difference between Kochi and Okayama (ΔPR) with greater equal to 30 mm/day. In addition, such large daily ΔPR was mainly due to the intense rainfall at Kochi with greater equal to 10mm/h throughout the warm season, except for a part of the cases in April when the “not so intense rain” with less than 10mm/h at Kochi contributed to the large ΔPR. However, it is noted that the features of the synoptic-scale atmospheric fields and possible roles of the mountain ranges in Shikoku District causing the large ΔPR were rather different among August (midsummer), September (Autumn rainfall season) and April (Spring) . en-copyright= kn-copyright= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= en-aut-name=SUGIMURAYuki en-aut-sei=SUGIMURA en-aut-mei=Yuki kn-aut-name=杉村裕貴 kn-aut-sei=杉村 kn-aut-mei=裕貴 aut-affil-num=2 ORCID= en-aut-name=MATSUMOTOKengo en-aut-sei=MATSUMOTO en-aut-mei=Kengo kn-aut-name=松本健吾 kn-aut-sei=松本 kn-aut-mei=健吾 aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 en-keyword=Daily precipitation climatology kn-keyword=Daily precipitation climatology en-keyword=Climate around Japan kn-keyword=Climate around Japan en-keyword=Seto Inland Sea Climate in Japan kn-keyword=Seto Inland Sea Climate in Japan en-keyword=Synoptic climatology kn-keyword=Synoptic climatology END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=25 end-page=36 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Interdisciplinary ESD lesson study for the university students with attention to the difference of climate and seasonal feeling in “summer” among Germany, northern Europe and Japan kn-title=ドイツ・北欧と日本の「夏」の気候や季節感の違いに注目して音楽と連携した大学での学際的ESD授業開発 en-subtitle= kn-subtitle= en-abstract= kn-abstract= Climatological features and seasonal feeling in the season called by the same word such as “summer”would be rather different from region to region. Comparison of these features among the different regions, including the regions which are not so familiar to the students, would help to promote their fundamental ESD literacy, especially relating to the “Understanding of heterogeneous others”. Based on that concept, this paper will report an interdisciplinary lesson study for the university students on a theme how different the summertime climate and seasonal feeling among Germany, northern Europe and Japan are. In this study, the lesson practice was made in 2015 and 2018. In both classes, after the lecture on the summertime climate and seasonal feeling in these regions, the students created substitute songs with use of the melody of “Alles neu macht der Mai” (“The May makes all things new”, the same melody as a Japanese school song “Butterfly”) for the comparison between Germany and Japan. As for that between northern Europe, the melody of a Japanese school song “Furu-Sato” (“My country home”) was used for the creation of the substitute songs. It is noted that, not only the seasonal mean temperature or solar radiation condition, but also the features in association with the large day-to-day temperature variation was strongly reflected in the students’ works. en-copyright= kn-copyright= en-aut-name=KATOKuranoshin en-aut-sei=KATO en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= en-aut-name=KATOHaruko en-aut-sei=KATO en-aut-mei=Haruko kn-aut-name=加藤晴子 kn-aut-sei=加藤 kn-aut-mei=晴子 aut-affil-num=2 ORCID= en-aut-name=OTANIKazuo en-aut-sei=OTANI en-aut-mei=Kazuo kn-aut-name=大谷和男 kn-aut-sei=大谷 kn-aut-mei=和男 aut-affil-num=3 ORCID= en-aut-name=MATSUMOTOKengo en-aut-sei=MATSUMOTO en-aut-mei=Kengo kn-aut-name=松本健吾 kn-aut-sei=松本 kn-aut-mei=健吾 aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Faculty of Education, Gufu Shotoku Gakuen University kn-affil=岐阜聖徳学園大学教育学部 affil-num=3 en-affil=TV Setouchi Broadcasting Co., LTD. kn-affil=テレビせとうち(株) affil-num=4 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 en-keyword=Interdisciplinary collaboration between climate and cultural understanding education kn-keyword=Interdisciplinary collaboration between climate and cultural understanding education en-keyword=ESD kn-keyword=ESD en-keyword=Comparative climatology kn-keyword=Comparative climatology en-keyword=Regional difference of summer climate kn-keyword=Regional difference of summer climate END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=19 end-page=24 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Schistose fault related rocks from the Sangun Metamorphic Rocks, Kawakita area, Misaki Town, Okayama Prefecture, SW Japan kn-title=美咲町川北地域に分布する三郡変成岩から見出された片岩化した断層岩 en-subtitle= kn-subtitle= en-abstract= kn-abstract= The crystalline schist which is representatively exposed in the Innerside of Southwest Japan is called the Sangun Metamorphic Rocks (SMR). In Kawakita area, Misaki Town, Okayama Prefecture, schistose fault rocks which is newly described in below are intercalated in the SMR. The rocks are composed of lenticular fragments of pelitic, basic siliceous rocks and quartz vein with siliceous to pelitic matrix. The fine-grained muscovites which define schistosity penetrate the rocks. Major direction of layer which though to reflect slip plane is subparallel to the schistosity. The long axis of some fragments are slightly oblique to the schistosity. The combination of the two sets of planes is considered to be a composite planar fabric. These occurrences suggest that the rocks are fault rock before the Sangun Metamorphism and named as schistose fault rocks. Lenses of cataclasite and myronite are accompanied. Planar thin (about 10cm in thickness) brittle fault rock is also associated. These shear deformed rocks form units of layer (shear zone) of 10 to 100m in thickness, and are concordantly intercalated in the surrounded normal schists. Active periods of the shear zones had several times from before and after the event of the Sangun Metamorphism. en-copyright= kn-copyright= en-aut-name=MATSUSHITAMirei en-aut-sei=MATSUSHITA en-aut-mei=Mirei kn-aut-name=松下実礼 kn-aut-sei=松下 kn-aut-mei=実礼 aut-affil-num=1 ORCID= en-aut-name=SUZUKIShigeyuki en-aut-sei=SUZUKI en-aut-mei=Shigeyuki kn-aut-name=鈴木茂之 kn-aut-sei=鈴木 kn-aut-mei=茂之 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 en-keyword=Sangun Metamorphic Rocks kn-keyword=Sangun Metamorphic Rocks en-keyword=regional metamorphism kn-keyword=regional metamorphism en-keyword=shear deformation kn-keyword=shear deformation en-keyword=schistose fault rock kn-keyword=schistose fault rock END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=1 end-page=17 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Computation of non-linear site response by the time-domain finite-difference method kn-title=時間領域差分法による表層地盤の非線形応答の計算 en-subtitle= kn-subtitle= en-abstract= kn-abstract= We have developed a time-domain staggered-grid finite-difference code for modeling non-linear response of a one-dimensionally inhomogeneous subsurface structure to a SH plane-wave incidence. It employs the velocity-stress formulation of elastodynamic equation for the linear part, and adopts a elastoplastic rheology model for the non-linear relation between the stress and strain. In this paper, we apply this code to four constitutive models from linear-elastic to nonlinear: (1) linear elastic model, (2) linear viscoelastic model, (3) elastoplastic model, and (4) viscoelastoplastic model, which simulate shallow sand and clay structures and are vibrated by a vertically incident SH plane-wave of Ricker wavelet, to compare the linear and the non-linear soil behaviors including low strains damping (viscoelastic effect) and/or hysteretic attenuation (non-linear effect). We also apply it to a local strong-motion record of the 2000 Western-Tottori earthquake (MW6.8). We then simulate characteristics of non-linear site response such as reduction of the spectral amplitude in the high frequency band and shift of the peak frequencies to lower frequencies. en-copyright= kn-copyright= en-aut-name=TORIGOEYusuke en-aut-sei=TORIGOE en-aut-mei=Yusuke kn-aut-name=鳥越友輔 kn-aut-sei=鳥越 kn-aut-mei=友輔 aut-affil-num=1 ORCID= en-aut-name=KOMATSUMasanao en-aut-sei=KOMATSU en-aut-mei=Masanao kn-aut-name=小松正直 kn-aut-sei=小松 kn-aut-mei=正直 aut-affil-num=2 ORCID= en-aut-name=TAKENAKAHiroshi en-aut-sei=TAKENAKA en-aut-mei=Hiroshi kn-aut-name=竹中博士 kn-aut-sei=竹中 kn-aut-mei=博士 aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Earth Sciences, Faculty of Science, Okayama University kn-affil=岡山大学理学部地球科学科 affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 en-keyword=finite-difference method kn-keyword=finite-difference method en-keyword=non-linear site response kn-keyword=non-linear site response en-keyword=strong motion kn-keyword=strong motion END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Title Page en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20191227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue=2-3 article-no= start-page=1 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200319 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Preliminary Study on Classification of Financial Ratios Using Factor Analysis kn-title=因子分析による財務比率の分類に関する予備的研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The purpose of this paper is to perform factor analysis on financial ratios calculated using consolidated financial statement data from the fiscal year ended March 31, 2006 to the fiscal year ended March 31, 2017, which are disclosed by Japanese companies, and to classify financial ratios.
　The analysis provided evidence to suggest that both net income and cash flows from operating activities are functioned as financial performance measures with similar properties. We also find that capital efficiency is an important factor. Furthermore, there is also evidence that cash flows from investing activities and cash flows from financing activities have a common factor. en-copyright= kn-copyright= en-aut-name=NakagawaToyotaka en-aut-sei=Nakagawa en-aut-mei=Toyotaka kn-aut-name=中川豊隆 kn-aut-sei=中川 kn-aut-mei=豊隆 aut-affil-num=1 ORCID= en-aut-name=NagahataHidekazu en-aut-sei=Nagahata en-aut-mei=Hidekazu kn-aut-name=長畑秀和 kn-aut-sei=長畑 kn-aut-mei=秀和 aut-affil-num=2 ORCID= en-aut-name=YamanishiYuki en-aut-sei=Yamanishi en-aut-mei=Yuki kn-aut-name=山西佑季 kn-aut-sei=山西 kn-aut-mei=佑季 aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil=岡山大学大学院社会文化科学研究科 affil-num=2 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil=岡山大学大学院社会文化科学研究科 affil-num=3 en-affil= kn-affil=熊本県立大学総合管理学部 END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue= article-no= start-page=12 end-page=17 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201906 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Species identification of a laboratory strain belonging to the family Arvicolinae kn-title=種名が不明なミズハタネズミ亜科系統の種の同定 en-subtitle= kn-subtitle= en-abstract= kn-abstract= This study investigated the taxonomic status of a laboratory strain belonging to the family Arvicolinae for which the wild species name is unknown.

The subdivision was based on the assumption that metamorphism occurred at ca. 116 Ma, largely based on an early Rb-Sr isotope study and zircon data obtained for the eclogite unit of the Sanbagawa Belt, whereas in some parts of the belt detrital zircons of late Cretaceous age (90-80 Ma) were discovered. Analysis of detrital zircons sampled from two sites within the area considered to expose the older ‘Sanbagawa Metamorphic Rocks’, including the area investigated by the Rb-Sr study, reveals the presence of zircons younger than 95 Ma in all samples and some grains as young as 80 ± 4 Ma. It is therefore concluded that the Sanbagawa Belt is one single tectonic entity that formed in the Late Cretaceous though it contains older components, including fossiliferous clasts, older basic meta-volcanics and eclogite units that may record earlier metamorphic events. en-copyright= kn-copyright= en-aut-name=KnittelUlrich en-aut-sei=Knittel en-aut-mei=Ulrich kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WaliaMonika en-aut-sei=Walia en-aut-mei=Monika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=LeeYuan-Hsi en-aut-sei=Lee en-aut-mei=Yuan-Hsi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Clay and Interface Mineralogy, RWTH Aachen University kn-affil= affil-num=2 en-affil=Department of Geosciences, National Taiwan University kn-affil= affil-num=3 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=4 en-affil=Department of Earth and Environmental Sciences, National Chung-Cheng University kn-affil= en-keyword=U-Pb zircon dating kn-keyword=U-Pb zircon dating en-keyword=Sanbagawa Metamorphic Belt kn-keyword=Sanbagawa Metamorphic Belt en-keyword=Late Cretaceous kn-keyword=Late Cretaceous en-keyword=Asemi River kn-keyword=Asemi River END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=31 end-page=38 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A new method of terrace analysis to determine precise altitudes of former shoreline en-subtitle= kn-subtitle= en-abstract= kn-abstract= The study area is situated in Japan Sea side margin of the Shakotan Peninsula, Hokkaido, Japan, where MIS5e Terrace is preserved along the cost. Numbers of tight drilling have done to establish new method for terrace analysis. Buried wave cut terrace and sea cliff (when the MIS5e Terrace was formed) are reconstructed by distribution of the terrace deposits and these bottom of unconformity planes. The precise site and altitude of former shoreline was also obtained. Altitudes of the former shoreline from the 7 sections are almost the same 22 to 27m in height. Previous data of the height of shoreline are obtained from the topographic MIS5e Terrace surface. The altitudes have variation from 30m to 60m. It suggests that the traditional method for the MIS5e terrace analysis had some errors in the study area. en-copyright= kn-copyright= en-aut-name=AmanoHideki en-aut-sei=Amano en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatoMasaru en-aut-sei=Sato en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YanagidaMakoto en-aut-sei=Yanagida en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Hanshin Consultants Co., Ltd., kn-affil= affil-num=4 en-affil=Hanshin Consultants Co., Ltd., kn-affil= en-keyword=MIS5e kn-keyword=MIS5e en-keyword=marine terrace kn-keyword=marine terrace en-keyword=terrace deposits kn-keyword=terrace deposits en-keyword=tight drilling kn-keyword=tight drilling en-keyword=shoreline kn-keyword=shoreline END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=19 end-page=30 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Development of an interdisciplinary study plan on the seasonal transition from autumn to winter around the Japan Islands (Through the lesson study at junior high school with attention to the shallow convective rainfall “Shi-gu-re” in the cold air outbreak situations in early winter) kn-title=日本の秋から冬への季節の変化を捉える学際的指導法の開発（初冬の時雨に注目した附属中学校での実践） en-subtitle= kn-subtitle= en-abstract= kn-abstract= An interdisciplinary study plan on the seasonal transition from autumn to winter around the Japan Islands and the “seasonal feeling” associated with the shallow convective rainfall “Shi-gu-re” in that stage expressed in the Japanese classic poems called “Wa-ka” was developed, through a lesson study at junior high school. In that study plan, special attention was paid to the seasonal evolution of the larger-scale systems from autumn to winter, such as the Siberian air mass and the Siberian high, and the relation to the cold air intrusion into the Japan Sea and the Japan Islands. According to the analysis of the lesson practice results, students seem to understand that the winter-type weather pattern becomes dominant around November, together with the features of the intermittent rainfall in the winter-type pressure pattern called “Shi-gu-re” expressed in the “Wa-ka”. However, necessity of further improvement of the study plan was pointed out, so that the students can understand more exactly the role of the seasonal development of the Siberian high and Siberian air mass in the climate around the Japan Islands. en-copyright= kn-copyright= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= en-aut-name=NishikawaSari en-aut-sei=Nishikawa en-aut-mei=Sari kn-aut-name=西川紗里 kn-aut-sei=西川 kn-aut-mei=紗里 aut-affil-num=2 ORCID= en-aut-name=NakakuraToshimi en-aut-sei=Nakakura en-aut-mei=Toshimi kn-aut-name=中倉智美 kn-aut-sei=中倉 kn-aut-mei=智美 aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil= kn-affil= affil-num=3 en-affil=Attached Junior High School of Okayama University kn-affil=岡山大学教育学部附属中学校 en-keyword=Interdisciplinary collaboration between climate and cultural understanding education kn-keyword=Interdisciplinary collaboration between climate and cultural understanding education en-keyword=Climate environment around Japan kn-keyword=Climate environment around Japan en-keyword=Transition from autumn to winter around Japan kn-keyword=Transition from autumn to winter around Japan en-keyword=“Seasonal feeling” in early winter expressed in the Japanese classic literature kn-keyword=“Seasonal feeling” in early winter expressed in the Japanese classic literature en-keyword=ESD kn-keyword=ESD END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=7 end-page=17 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Synoptic climatological analyses on the large day-to-day variation of air temperature around Germany in winter (Relating to the “seasonal feeling” in “Fasnacht”, the festival for driving the winter away) kn-title=ドイツ付近の冬における日々の大きな気温変動に関する総観気候学的解析（冬の追い出しの行事「ファスナハト」における季節感に関連して） en-subtitle= kn-subtitle= en-abstract= kn-abstract= Synoptic climatological analyses associated with the large day-to-day variation of air temperature around Germany in winter were performed based mainly on the NCEP/NCAR reanalysis data for 2000/2001 to 2010/2011 winters, with an interest in the relationship to the “seasonal feeling” in “Fasnacht”, the festival for driving the winter away. The intermittent appearance of the extremely cold days with rather large day-to-day variation in winter as pointed out by Kato et al. (2017) for around Germany was seen also to the north and to the east of Germany. According to a case study for the 2000/2001 winter, such large daily mean temperature fluctuation was closely related to the intraseasonal variation of the Icelandic low with about one month period, i.e., while the temperature around Germany was relatively higher at the eastward shift phase of the Icelandic low due to the strong warm air advection by the SW-ly wind, the temperature was extremely low there when the Icelandic low was weakened and retreated westward. en-copyright= kn-copyright= en-aut-name=HamakiTatsuya en-aut-sei=Hamaki en-aut-mei=Tatsuya kn-aut-name=濱木達也 kn-aut-sei=濱木 kn-aut-mei=達也 aut-affil-num=1 ORCID= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=2 ORCID= en-aut-name=OtaniKazuo en-aut-sei=Otani en-aut-mei=Kazuo kn-aut-name=大谷和男 kn-aut-sei=大谷 kn-aut-mei=和男 aut-affil-num=3 ORCID= en-aut-name=KatoHaruko en-aut-sei=Kato en-aut-mei=Haruko kn-aut-name=加藤晴子 kn-aut-sei=加藤 kn-aut-mei=晴子 aut-affil-num=4 ORCID= en-aut-name=MatsumotoKengo en-aut-sei=Matsumoto en-aut-mei=Kengo kn-aut-name=松本健吾 kn-aut-sei=松本 kn-aut-mei=健吾 aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=3 en-affil=TV Setouchi Broadcasting Co., LTD. kn-affil=テレビせとうち(株) affil-num=4 en-affil=Faculty of Education, Gifu Shotoku Gakuen University kn-affil=岐阜聖徳学園大学教育学部 affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 en-keyword=Comparative climatology kn-keyword=Comparative climatology en-keyword=Climate around Europe kn-keyword=Climate around Europe en-keyword=Synoptic climatology on daily temperature variation in winter around Germany kn-keyword=Synoptic climatology on daily temperature variation in winter around Germany en-keyword=seasonal cycle and “seasonal feeling” kn-keyword=seasonal cycle and “seasonal feeling” END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page=1 end-page=5 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Non-calcareous beachrock found in Akagurisaki, Ohi Town, Fukui Prefecture kn-title=福井県おおい町赤礁崎で見出された非石灰質ビーチロック en-subtitle= kn-subtitle= en-abstract= kn-abstract= Beachrock which was formed about 0.5 meter higher than high tide is found in Akagurisaki, Ohi Town, Fukui Prefecture.

Intergranular space is occupied by white amorphous cement. Magnesium and silicon rich composition of the cement is obtained by EPMA analysis. There is a conjecture that the magnesium rich cement was precipitated in spite of solution of calcareous shell under saturated state by spring water, because calcium has a higher tendency to ionize than magnesium. en-copyright= kn-copyright= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name=鈴木茂之 kn-aut-sei=鈴木 kn-aut-mei=茂之 aut-affil-num=1 ORCID= en-aut-name=AzumaYoichi en-aut-sei=Azuma en-aut-mei=Yoichi kn-aut-name=東洋一 kn-aut-sei=東 kn-aut-mei=洋一 aut-affil-num=2 ORCID= en-aut-name=DeyamaYasuyo en-aut-sei=Deyama en-aut-mei=Yasuyo kn-aut-name=出山康代 kn-aut-sei=出山 kn-aut-mei=康代 aut-affil-num=3 ORCID= en-aut-name=YukawaHirokazu en-aut-sei=Yukawa en-aut-mei=Hirokazu kn-aut-name=湯川弘一 kn-aut-sei=湯川 kn-aut-mei=弘一 aut-affil-num=4 ORCID= en-aut-name=UsuiMayumi en-aut-sei=Usui en-aut-mei=Mayumi kn-aut-name=臼井まゆみ kn-aut-sei=臼井 kn-aut-mei=まゆみ aut-affil-num=5 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil=平寺町松岡兼定島 4-1-1 ** kn-affil=福井県立大学恐竜学研究所 affil-num=3 en-affil=平寺町松岡兼定島 4-1-1 ** kn-affil=福井県立大学恐竜学研究所 affil-num=4 en-affil=Fukui Prefectural Dinosaur Museum kn-affil=福井県立恐竜博物館 affil-num=5 en-affil=Fujigakuin-Okayama kn-affil=富士学院 en-keyword=Beachrock kn-keyword=Beachrock en-keyword=Akagurisaki kn-keyword=Akagurisaki en-keyword=non-calcareous cement kn-keyword=non-calcareous cement en-keyword=ionization tendency kn-keyword=ionization tendency END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Title Page en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20181227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20171227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=裏表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20171227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学地球科学研究報告 投稿規定（約款） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=5 end-page=18 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20171227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Interdisciplinary class for high school students on the climate environment around Japan and "seasonal feeling" expressed in the school songs with attention to the asymmetric seasonal march from autumn to the next spring kn-title=日本の気候環境と愛唱歌などにみる季節感に関する高校での学際的授業の開発（冬を挟む日本の季節進行の非対称性に注目して） en-subtitle= kn-subtitle= en-abstract= kn-abstract= This study is a part of the activity to develop an interdisciplinary lesson plan for high school students on the climate environment around Japan and the "seasonal feeling". This time, we focused our attention to the asymmetric seasonal march from autumn to the next spring as proposed by Kato et al. (2013). Comparison of the climate between early winter and early spring was made in the class not only on that around the Japan but also on the relation to the larger-scale systems such as the Siberian air mass, including the brief data analysis. The students also compared the detailed "seasonal feeling" between the two seasons expressed in the school songs and the Japanese classic poems called "Wa-Ka". This paper reports the contents and results of this joint activity at the two high schools. en-copyright= kn-copyright= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=1 ORCID= en-aut-name=KatoHaruko en-aut-sei=Kato en-aut-mei=Haruko kn-aut-name=加藤晴子 kn-aut-sei=加藤 kn-aut-mei=晴子 aut-affil-num=2 ORCID= en-aut-name=MiyakeShoji en-aut-sei=Miyake en-aut-mei=Shoji kn-aut-name=三宅昭二 kn-aut-sei=三宅 kn-aut-mei=昭二 aut-affil-num=3 ORCID= en-aut-name=MoriTaizo en-aut-sei=Mori en-aut-mei=Taizo kn-aut-name=森泰三 kn-aut-sei=森 kn-aut-mei=泰三 aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科（理科） affil-num=2 en-affil=Faculty of Education, Gufu Shotoku Gakuen University kn-affil=岐阜聖徳学園大学教育学部（音楽） affil-num=3 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科（理科） affil-num=4 en-affil=Okayama-Ichinomiya High School kn-affil=岡山県一宮高等学校（地理） en-keyword= Interdisciplinary activity on climate and cultural understanding education kn-keyword= Interdisciplinary activity on climate and cultural understanding education en-keyword= Climate environment around Japan kn-keyword= Climate environment around Japan en-keyword=Seasonal cycle and "seasonal feeling" kn-keyword=Seasonal cycle and "seasonal feeling" en-keyword=Asymmetric seasonal march from autumn to the next spring kn-keyword=Asymmetric seasonal march from autumn to the next spring en-keyword=ESD kn-keyword=ESD END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=1 end-page=4 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20171227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Rounded pebble of metamorphosed iron-formations from conglomerate of the Miocene deposits in Yatakayama, Kibi Plateau, Okayama Prefecture kn-title=岡山県吉備高原弥高山地域に分布する中新統礫岩から変成鉄鉱石礫の発見 en-subtitle= kn-subtitle= en-abstract= kn-abstract= The Kibi Plateau was a part of the Eurasian Continent and separated by the event of opening of Japan Sea. The rounded pebble which is considered to be continental origin was discovered. The pebble is siliceous and attracts magnets. Prepared thin-sections were observed under microscope. Selected minerals were analyzed by EPMA. The rock is composed of recrystallized quartz, magnetite, riebeckite, stilpnomelane and associated with very tiny minerals with very high relief and interference colors. The assemblage suggests that there is a possibility that the rock is a metamorphic rock of iron-formations and derived from continent. en-copyright= kn-copyright= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name=鈴木茂之 kn-aut-sei=鈴木 kn-aut-mei=茂之 aut-affil-num=1 ORCID= en-aut-name=小網晴男 en-aut-sei=小網 en-aut-mei=晴男 kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=臼井まゆみ en-aut-sei=臼井 en-aut-mei=まゆみ kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil=Okayama Prefectural Okayama Asahi Senior High School kn-affil=岡山県立岡山朝日高等学校 affil-num=3 en-affil=Fujigakuin-Okayama kn-affil=富士学院 en-keyword=Continental origin kn-keyword=Continental origin en-keyword=Miocene conglomerate kn-keyword=Miocene conglomerate en-keyword=rounded pebble kn-keyword=rounded pebble en-keyword=iron-formations kn-keyword=iron-formations en-keyword=Kibi Plateau kn-keyword=Kibi Plateau END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20171227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Title Page en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20171227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue= article-no= start-page=21 end-page=27 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=201804 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Cytoskeletal elements in an acoelomorph worm, Praesagittifera naikaiensis kn-title=無腸動物Praesagittifera naikaiensis における細胞骨格要素 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Acoel flatworms can move in a variety of ways such as muscular and ciliary movements via cytoskeletal elements and their neural regulations. However, those locomotive mechanisms have not yet been fully elucidated. In this study, we examined the distribution of cytoskeletal elements including filamentous actin (F-actin) and tubulin, and the neuroanatomical organization in an acoelomorph worm, Praesagittifera naikaiensis (P. naikaiensis). Video microscopy revealed the elongation/contraction and the bending/rotation processes, and the ciliary gliding movement of P. naikaiensis. Histochemical and morphological analysis demonstrated that F-actin networks of inner longitudinal and outer circular muscle fibers were positioned along the entire surface of the body, and that the average distance between the circular muscle fibers in the contracted organism was decreased in the anterior region compared with that in the elongated organism. Electron microscopy showed dense bodies on the muscle cells of P. naikaiensis, which indicates that those muscle cells have the appearance of vertebrate smooth muscle cells. Immunohistochemical analysis revealed that ?-tubulin-positive signals on the ciliary microtubules had close contact with the F-actin network, and that neurite bundles labelled with anti dSap47 antibody as a neuronal marker run along the anterior-posterior body axis. These results indicate that the well-organized cytoskeletal elements and their neural control systems are preserved in P. naikaiensis, and that their mechanisms involved in those regulation systems are similar to those vertebrate systems. Further studies are needed to clarify the physiological mechanisms underlying the muscular and ciliary movements in P. naikaiensis. en-copyright= kn-copyright= en-aut-name=IkedaRisa en-aut-sei=Ikeda en-aut-mei=Risa kn-aut-name=池田理佐 kn-aut-sei=池田 kn-aut-mei=理佐 aut-affil-num=1 ORCID= en-aut-name=FujiwaraChiho en-aut-sei=Fujiwara en-aut-mei=Chiho kn-aut-name=藤原稚穂 kn-aut-sei=藤原 kn-aut-mei=稚穂 aut-affil-num=2 ORCID= en-aut-name=HamadaMayuko en-aut-sei=Hamada en-aut-mei=Mayuko kn-aut-name=濱田麻友子 kn-aut-sei=濱田 kn-aut-mei=麻友子 aut-affil-num=3 ORCID= en-aut-name=SakamotoTatsuya en-aut-sei=Sakamoto en-aut-mei=Tatsuya kn-aut-name=坂本竜哉 kn-aut-sei=坂本 kn-aut-mei=竜哉 aut-affil-num=4 ORCID= en-aut-name=SaitoNoboru en-aut-sei=Saito en-aut-mei=Noboru kn-aut-name=齋藤昇 kn-aut-sei=齋藤 kn-aut-mei=昇 aut-affil-num=5 ORCID= en-aut-name=AndoMotonori en-aut-sei=Ando en-aut-mei=Motonori kn-aut-name=安藤元紀 kn-aut-sei=安藤 kn-aut-mei=元紀 aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=3 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil=岡山大学・理学部附属臨海実験所 affil-num=4 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil=岡山大学・理学部附属臨海実験所 affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 affil-num=6 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 END start-ver=1.4 cd-journal=joma no-vol=49 cd-vols= no-issue=3 article-no= start-page=109 end-page=120 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180319 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The current situation and problems of China’s Long-term Care Insurance System kn-title=中国における介護保険制度の試行現状と課題 en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper uses the latest statistics of the National Bureau of Statistics to analyze the characteristics of China's population aging.

As an important barrier to the aging population, the long-term care insurance system has the advantages of using the market-oriented principle to reform the elderly care service market and realize the social distribution of the elderly’s maintenance responsibility. However, China’s long-term care insurance system, which is in the trial operation process, still has some drawbacks, we will be focusing on how to get rid of these shortcomings of the system as core issues of the reform. en-copyright= kn-copyright= en-aut-name=ZhangJian en-aut-sei=Zhang en-aut-mei=Jian kn-aut-name=張建 kn-aut-sei=張 kn-aut-mei=建 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=中国海南医学院管理学部 END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20161227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=裏表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20161227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学地球科学研究報告 投稿規定（約款） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=33 end-page=42 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20161227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A case study on the cyclone activity around Europe from winter to spring of 2000 kn-title=ヨーロッパの冬から春にかけての 低気圧活動に関する事例解析（2000年を例に） en-subtitle= kn-subtitle= en-abstract= kn-abstract= Although the extratropical cyclone is one of the basic systems that characterize the weather and climate in mid-latitude regions with the large meridional temperature gradient, its activity and characteristics would be greatly influenced by the seasonal transition and regional differences of the mean atmospheric fields such as between Europe and East Asia. Furthermore, detailed knowledge of the daily cyclone activity would help to understand deeply the differences of regional climatology including seasonal cycles among various areas. In such interest, the present study performed a case study on the cyclone activity around Europe from winter to spring of 2000. In winter, intraseasonal variation of the Icelandic Low was dominant. In the stage when such intraseasonal-scale Icelandic Low approached to the northwestern Europe, the several lows passed eastward with a few days interval around the intraseasonal-scale low pressure area or its southern edge where the baroclinicity was relatively strong. It is also noted that their center pressure was rather low (below 980hPa). After April, when the seasonal mean Icelandic low had disappeared, different types of the intra-seasonal-scale cyclones and anticyclones were dominantly observed. In the lower SLP stage of the intraseasonal variation in Europe, the low to the southwest of England in the middle of April was of the equivalent barotropic structure and persisted for about ten days. On the other hand, high pressure area extending from England to the northern coast of Germany also persisted for about half month. The southern half of that high area was also of equivalent barotropic structure with warmer air there. en-copyright= kn-copyright= en-aut-name=KuwanaYusuke en-aut-sei=Kuwana en-aut-mei=Yusuke kn-aut-name=桑名佑典 kn-aut-sei=桑名 kn-aut-mei=佑典 aut-affil-num=1 ORCID= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=2 ORCID= en-aut-name=TakigawaYumi en-aut-sei=Takigawa en-aut-mei=Yumi kn-aut-name=瀧川優実 kn-aut-sei=瀧川 kn-aut-mei=優実 aut-affil-num=3 ORCID= en-aut-name=KojimaYumi en-aut-sei=Kojima en-aut-mei=Yumi kn-aut-name=小嶋ゆう実 kn-aut-sei=小嶋 kn-aut-mei=ゆう実 aut-affil-num=4 ORCID= en-aut-name=OtaniKazuo en-aut-sei=Otani en-aut-mei=Kazuo kn-aut-name=大谷和男 kn-aut-sei=大谷 kn-aut-mei=和男 aut-affil-num=5 ORCID= affil-num=1 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学教育部 （理科 ） affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学院教育研究科自然系 （理科 ） affil-num=3 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学教育部 （理科 ） affil-num=4 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学教育部 （理科 ） affil-num=5 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil=岡山大学院自然科学研究科 en-keyword=cyclone activity around Europe kn-keyword=cyclone activity around Europe en-keyword=comparative climatology between Europe and East Asia kn-keyword=comparative climatology between Europe and East Asia en-keyword=seasonal cycle kn-keyword=seasonal cycle en-keyword=dynamic climatology kn-keyword=dynamic climatology END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=17 end-page=32 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20161227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Synoptic climatological analyses on the rainfall features in southern Kyushu and the atmospheric fields around April kn-title=九州南部における4月頃の大雨日の降水の特徴と 大気場に関する総観気候学的解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract= Around April, total precipitation in southern Kyushu already attains rather large value due to the increase in contribution of the “heavy rainfall days” (with daily precipitation more the 50 mm/day, referred to as HRD). The present study examined the rainfall features and atmospheric conditions on the HRDs at Kagoshima in southern Kyushu, based on the operational observation data from 1990 to 2009. The HRDs there in April appeared mainly associated with the extratropical cyclone passage, together with tentative appearance of the stationary front. The mean daily precipitation on the HRDs was 82 mm and contribution of the intense rainfall more than 10 mm/h attained up to 38 mm, which accounted for 46 % of the daily total precipitation. In April, the high specific humidity area in the time mean field was still located far to the south of the Japan Islands and the stratification around the Japan Islands was very stable for deep moist convection.

The field survey was concentrated in the coast of Shiofuki-iwa, Miyama Complex, Hidakagawa Belt where soft deformations penetrate throughout the m?lange unit. Brittle to ductile faults associated as later deformations are excluded. The m?lange unit is subdivided into the Y-shear zone (YSZ) and P-foliation zone (PFZ). The YSZ is composed of thick lenticular sandstone (trends subparallel to the direction of the m?lange), intense shear band (thin layer with concentrated prelithification shear deformation) and mudstone dominant m?lange. The PFZ is composed of mudstone dominant m?lange (associated with foliations which slightly oblique to the direction of the YSZ) and lenticular sandstone (slightly oblique to the direction of the YSZ). The intense shear band separates the YSZ and PFZ. Preserved radiolarian fossils free from deformation in the intense shear band is the evidence of the prelithification shear deformation in the m?lange. A remarkable-fact is that the structures of m?lange unit are formed under sinistral sense of shear. The m?lange unit in the Shiofuki-iwa is ascribed to be formed by sinistral sense of shear during sediments were prelithified. en-copyright= kn-copyright= en-aut-name=TakesueNorito en-aut-sei=Takesue en-aut-mei=Norito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=m?lange kn-keyword=m?lange en-keyword=Shimanto Belt kn-keyword=Shimanto Belt en-keyword=Y-shear zone kn-keyword=Y-shear zone en-keyword=P-foliation zone kn-keyword=P-foliation zone en-keyword=intense shear band kn-keyword=intense shear band en-keyword=prelithification structures kn-keyword=prelithification structures END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=1 end-page=7 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=20161227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Risk prediction of landslide and debris flow using slope gradation map obtained from airborne laser scanning kn-title=航空レーザ傾斜量図を用いた斜面・土石流危険箇所抽出の試み en-subtitle= kn-subtitle= en-abstract= kn-abstract= The slope gradation map which is obtained from airborne laser scanning is very important tool to detect hazardous sites of landslide, debris flow and others.

The map helps to distinguish between artificial microrelief and natural microtopography very well. Small scarps (even 0.5m high), rocky cliffs and large blocks (larger than 2m) are identified in the map. The detail images of the microrelief suggest threatening sites. The merit of the map leads us to find the site in the field easily.

In the present study, we investigated the taxonomic status of the Aco strain, which is derived from spiny mice of an unidentified species. Although this Aco strain has been tentatively considered A. cahirinus species, it was distinguished from this species based on conventional and G-banding chromosomal patterns of this strain. Subsequently, we determined the nucleotide sequence of the mitochondorial gene cytochrome b (Cyb) and constructed a molecular phylogenetic tree. We found that the Aco strain belongs to the same clade as A. dimidiatus. Based on this molecular analysis, we concluded that the Aco strain of spiny mice should be considered A. dimidiatus. en-copyright= kn-copyright= en-aut-name=MochidaHitomi en-aut-sei=Mochida en-aut-mei=Hitomi kn-aut-name=持田瞳 kn-aut-sei=持田 kn-aut-mei=瞳 aut-affil-num=1 ORCID= en-aut-name=MekadaKazuyuki en-aut-sei=Mekada en-aut-mei=Kazuyuki kn-aut-name=目加田和之 kn-aut-sei=目加田 kn-aut-mei=和之 aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Zoology, Faculty of Science, Okayama University of Science kn-affil=岡山理科大学 理学部 動物学科 affil-num=2 en-affil=Department of Zoology, Faculty of Science, Okayama University of Science kn-affil=岡山理科大学 理学部 動物学科 END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue= article-no= start-page=2 end-page=2 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201704 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Breeding and genetics of mutant strains and domestication of wildlife for laboratory animal science kn-title=ミュータント系実験動物育種と野生動物の実験動物化 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OdaSen-ichi en-aut-sei=Oda en-aut-mei=Sen-ichi kn-aut-name=織田銑一 kn-aut-sei=織田 kn-aut-mei=銑一 aut-affil-num=1 ORCID= affil-num=1 en-affil=Former Department of Zoology, Faculty of Science, Okayama University of Science kn-affil=元岡山理科大学理学部動物学科 END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue= article-no= start-page=12 end-page=18 dt-received= dt-revised= dt-accepted= dt-pub-year=2016 dt-pub=201604 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Animal Bio-Resources in the Department of Zoology, Faculty of Science, Okayama University of Science kn-title=岡山理科大学理学部動物学科における動物資源 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=JogaharaTakamichi en-aut-sei=Jogahara en-aut-mei=Takamichi kn-aut-name=城ヶ原貴通 kn-aut-sei=城ヶ原 kn-aut-mei=貴通 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山理科大学理学部動物学科 END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20151227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=裏表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20151227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学地球科学研究報告 投稿規定（約款） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=31 end-page=39 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20151227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Facies analysis of the Jito Formation ( Upper Triassic Nariwa Group ) in Jito Area, Kawakami, Okayama Pref., SWJapan. kn-title=岡山県川上町地頭地域における上部三畳系成羽層群地頭層の層相解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Facies analysis and analysis of stratigraphy together with folded structure of the Norian Jito Formation were studied in Jito Area, Kawakami, Okayama Pref., SW Japan.

For the experiments, the P-wave receiver functions are synthesized by assuming that a plane P wave is incident on an anisotropic multi-layer structure with anelastic properties. The synthetic receiver function shows smooth Ps phase waveforms with small amplitudes due to the attenuation of high-frequency spectral components, compared to that calculated for a multi-layer structure with perfect elasticity. From the shear-wave splitting of the Ps converted phases in the synthetic receiver functions, the S-wave polarization anisotropies for the anisotropic layers are measured as a function of propagation direction of the incident P wave. Consequently, we conclude that the seismic attenuation has a minor influence on the measurements of the S-wave polarization anisotropy. en-copyright= kn-copyright= en-aut-name=OdaHitoshi en-aut-sei=Oda en-aut-mei=Hitoshi kn-aut-name=小田仁 kn-aut-sei=小田 kn-aut-mei=仁 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部地球科学科 en-keyword=shear-wave polarization anisotropy kn-keyword=shear-wave polarization anisotropy en-keyword=shear-wave splitting kn-keyword=shear-wave splitting en-keyword=seismic attenuation kn-keyword=seismic attenuation en-keyword=Psconverted phase kn-keyword=Psconverted phase en-keyword=P-wave receiver function kn-keyword=P-wave receiver function END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20151227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=裏表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学地球科学研究報告 投稿規定（約款） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page=33 end-page=43 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Precipitation characteristics and large-scale atmospheric fields on the heavy rainfall days in the eastern part of Japan (Climatological features in midsummer and the supplemental study for the Baiu season) kn-title=東日本の大雨日の降水特性や総観場の解析（盛夏期の気候学的特徴と梅雨最盛期に関する補遺） en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Rainfall characteristics and large-scale atmospheric fields on the “heavy rainfall days” (with more than 50mm/day) in midsummer, and so on, at Tokyo in the eastern Japan were examined for 1971 to 2010, succeeding to Matsumoto et al. (2013) 　The present study firstly examined the rainfall features and the atmospheric fields for the “heavy rainfall days” at Tokyo with rather lower appearance frequency than in the typhoon related patterns in Matsumoto et al. (2013) and so on. In these cases (three cases in total), although the synoptic situations were rather different among each other, they seem to occur under the systems with relatively small zonal scale associated with the great meander of the upper-level westerly wind. 　Next, the climatological analyses similar to Matsumoto et al. (2013) were performed for the "heavy rain days" at Tokyo in midsummer (1~31 August). The precipitation on the “heavy rainfall days” at Tokyo in midsummer was mainly brought by the intense rainfall with more than 10 mm/h, as in the western Japan in the mature stage of the Baiu season. The detailed examination of the rainfall features for the case on 10 August 2009, with use of the 10-minutes precipitation data and the Radar AMeDAS Composite Data by the JMA, revealed that the organized meso-β-scale convective rainfall systems as often appear in the western Japan in the mature stage of the Baiu season were just to the east of the typhoon, and brought the intense rainfall at Tokyo to result in the large daily precipitation. en-copyright= kn-copyright= en-aut-name=MatusmotoKengo en-aut-sei=Matusmoto en-aut-mei=Kengo kn-aut-name=松本健吾 kn-aut-sei=松本 kn-aut-mei=健吾 aut-affil-num=1 ORCID= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=2 ORCID= en-aut-name=OtaniKazuo en-aut-sei=Otani en-aut-mei=Kazuo kn-aut-name=大谷和男 kn-aut-sei=大谷 kn-aut-mei=和男 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学教育学部（理科） affil-num=2 en-affil= kn-affil=岡山大学大学院教育学研究科自然教育学系（理科） affil-num=3 en-affil= kn-affil=岡山大学大学院自然科学研究科 en-keyword=rainfall characteristics in eastern Japan kn-keyword=rainfall characteristics in eastern Japan en-keyword=heavy rainfall in eastern Japan in the Baiu and midsummer seasons kn-keyword=heavy rainfall in eastern Japan in the Baiu and midsummer seasons en-keyword=rainfall climatology kn-keyword=rainfall climatology END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page=23 end-page=32 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A preliminary study on the seasonal cycles of the cyclone activity and the large-scale fields in Europe at the viewpoint comparing with those in East Asia kn-title=東アジアとの比較の視点でみたヨーロッパにおける低気圧活動と広域場の季節サイクル（序報） en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Preliminary analyses on the seasonal cycles of the large-scale atmospheric mean fields and the cyclone activity in Europe were performed based mainly on the NCEP/NCAR re-analysis data, at the viewpoint comparing with those in East Asia. 　As for the climatological monthly mean fields (1981~2010), the meridional temperature gradient in East Asia presents striking seasonal change with the maximum in winter and the minimum in summer. It is interesting that such transition from winter to summer and that from summer to winter occur rather rapidly accompanied by the great temperature increase around April to June and the decrease around October to November, respectively, in a wide region of 40~70N. On the other hand, the temperature gradient in Europe is significantly smaller with slight seasonal change than that in East Asian winter. 　By the way, in spite of the above difference of the horizontal temperature gradient between Europe and East Asia, the cyclone activity does not seem to be so weak even around Europe. Thus, the seasonal cycles of the characteristics of the cyclones and their environmental fields around Europe were examined. At the first step, we analyzed the daily cyclone activity in Europe for January and July of 2000. Many low pressure centers at the surface level appeared in both January and July. Referring also to the daily maps of sea level pressure and geopotential height at 500 hPa level, we found that not only the cyclones corresponding to the baroclinic instability waves, but also to the cold vortices which amplitudes increased with height appeared frequently. Moreover, it is interesting that the large-scale cold vortex, which embeds the shortwave trough with the low center at the surface level, appeared in the northern Europe in July as in East Asian winter, when such multi-scale systems sometimes bring the persisting heavy snowfall events in the Japan Sea side of the Japan Islands. en-copyright= kn-copyright= en-aut-name=TakigawaYumi en-aut-sei=Takigawa en-aut-mei=Yumi kn-aut-name=瀧川優実 kn-aut-sei=瀧川 kn-aut-mei=優実 aut-affil-num=1 ORCID= en-aut-name=HagaYuichi en-aut-sei=Haga en-aut-mei=Yuichi kn-aut-name=垪和優一 kn-aut-sei=垪和 kn-aut-mei=優一 aut-affil-num=2 ORCID= en-aut-name=MatsumotoKengo en-aut-sei=Matsumoto en-aut-mei=Kengo kn-aut-name=松本健吾 kn-aut-sei=松本 kn-aut-mei=健吾 aut-affil-num=3 ORCID= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学教育学部（理科） affil-num=2 en-affil= kn-affil=岡山大学大学院教育学研究科自然教育学系（理科） affil-num=3 en-affil= kn-affil=岡山大学教育学部（理科） affil-num=4 en-affil= kn-affil=岡山大学大学院教育学研究科自然教育学系（理科） en-keyword=seasonal cycle kn-keyword=seasonal cycle en-keyword=cyclone activity kn-keyword=cyclone activity en-keyword=Europe and East Asia kn-keyword=Europe and East Asia END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page=13 end-page=21 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Aerosol observation at Okayama with Skyradiometer and LIDAR kn-title=スカイラジオメーターとライダーを用いた岡山上空のエアロゾル観測 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　Aerosol is one of the controlling parameter for the global climate and also effects on local health hazards. The measurement of the aerosol was originally carried out as in-situ sampling and mass weight measurement including chemical analysis. Recently, remote sensing method is applied as satellite remote sensing and surface based remote sensing. Skyradiometer and LIDAR are surface based remote sensing system. Skyradiometer measures solar radiation as direct and scattered solar radiation affected by aerosols. LIDAR emit laser beam upward and it is backscattered by overlying aerosols. The backscattered light is received by a telescope and vertical distributions of the aerosols are obtained. These measurements require atmospheric radiation physics. 　A Skyradiometer and a LIDAR were operated continuously at Okayama University campus and aerosol parameters were obtained from both of the system. Seasonal variations of the AOT (Aerosol Optical Thickness) and Angstrom parameter (α) are evaluated. During some dust events (e.g. yellow sand and PM2.5), time variations of these parameters were identified from both of the measurement system. en-copyright= kn-copyright= en-aut-name=NagamatsuSinpei en-aut-sei=Nagamatsu en-aut-mei=Sinpei kn-aut-name=永松慎平 kn-aut-sei=永松 kn-aut-mei=慎平 aut-affil-num=1 ORCID= en-aut-name=EgawaDaiki en-aut-sei=Egawa en-aut-mei=Daiki kn-aut-name=江川大貴 kn-aut-sei=江川 kn-aut-mei=大貴 aut-affil-num=2 ORCID= en-aut-name=TsukamotoOsamu en-aut-sei=Tsukamoto en-aut-mei=Osamu kn-aut-name=塚本修 kn-aut-sei=塚本 kn-aut-mei=修 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil= kn-affil=岡山大学大学院自然科学研究科 en-keyword=Aerosol kn-keyword=Aerosol en-keyword=Skyradiometer kn-keyword=Skyradiometer en-keyword=LIDAR kn-keyword=LIDAR en-keyword=Aerosol Optical Thickness (AOT) kn-keyword=Aerosol Optical Thickness (AOT) END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page=7 end-page=11 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Paleoparadoxia from the middle Miocene of Obara, Misaki-cho, Okayama Prefecture, Japan kn-title=岡山県美咲町小原周辺に分布する中部中新統からのPaleoparadoxiaの産出報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract=　The partially preserved left humerus of the Desmostylia (Mammalia) has been collected from the riverbed in Obara, Misaki-cho, Okayama Prefecture in the western Japan.

The geospatial open data about the research field that used in the research were served by the government research institutes. The spatial analysis were executed by the R (R core team, 2014) and its spatial libraries, maptools (Bivand and Lewin-Koh, 2014), rgdal (Bivand, Keitt and Rowlingson, 2014) and gstat (Pebesma, 2014). The geospatial representation and qualitative analysis of the estimated distribution were performed by the QGIS (QGIS Development Team, 2014) and the Google earth (Google, 2014). The time variant of the PM2.5 concentration by the each observatories in the area were show some cross correlation factor to the SPM10 concentration data. The estimated PM2.5 distribution seems to show that the relatively tight relation to the geospatial factors in the research area. The estimation of a time variant change of the PM2.5 distribution will be required of the further research.. en-copyright= kn-copyright= en-aut-name=OmoriAkiho en-aut-sei=Omori en-aut-mei=Akiho kn-aut-name=大森秋穂 kn-aut-sei=大森 kn-aut-mei=秋穂 aut-affil-num=1 ORCID= en-aut-name=YamakawaJunji en-aut-sei=Yamakawa en-aut-mei=Junji kn-aut-name=山川純次 kn-aut-sei=山川 kn-aut-mei=純次 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部地球科学科 affil-num=2 en-affil= kn-affil=岡山大学理学部地球科学科 en-keyword=PM2.5 kn-keyword=PM2.5 en-keyword=Spatial statistics kn-keyword=Spatial statistics en-keyword=Kriging kn-keyword=Kriging en-keyword=R-language kn-keyword=R-language en-keyword=gstat kn-keyword=gstat en-keyword=FOSS4G kn-keyword=FOSS4G en-keyword=Google earth kn-keyword=Google earth END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Title Page en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=46 cd-vols= no-issue=2 article-no= start-page=119 end-page=131 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20141218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Relations Between Management Earnings Forecast Revisions and Returns kn-title=経営者予想利益の修正とリターンの関係 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=NakagawaToyotaka en-aut-sei=Nakagawa en-aut-mei=Toyotaka kn-aut-name=中川豊隆 kn-aut-sei=中川 kn-aut-mei=豊隆 aut-affil-num=1 ORCID= en-aut-name=YamanishiYuuki en-aut-sei=Yamanishi en-aut-mei=Yuuki kn-aut-name=山西佑季 kn-aut-sei=山西 kn-aut-mei=佑季 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=熊本県立大学総合管理学部 END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue= article-no= start-page=82 end-page=89 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20140310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Research on Quality Assurance in Teacher Training Course in Okayama University (2) ?

mature stage of the Baiu season kn-title=梅雨最盛期における東日本の大雨日の降水特性や総観場に関する気候学的解析（序報） en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rainfall characteristics and large-scale atmospheric fields on the “heavy rainfall days” (with more than 50 mm/day) in the mature stage of the Baiu season (16 June ~ 15 July) at Tokyo in the eastern part of the Japan Islands were examined, based on the daily and the hourly precipitation data from 1971 to 2010. Appearance frequency of the “heavy rainfall days” at Tokyo attained only about 1/3 of that at Nagasaki in the western Japan. Furthermore, it is noted that about half of the “heavy rainfall days” at Tokyo were related to the typhoon. In detail, about half of the typhoon cases were associated with the direct approach of a typhoon (referred to as Pattern A, hereafter), the other half corresponded to the situation when the Baiu front also stagnated around Kanto District with a typhoon to the southwest of Kanto (Pattern B). Although the contribution of the intense rainfall with more than 10 mm/h to the total precipitation was large in Pattern A, that with less than 10 mm/h was dominant in Patterns B and C (Pattern C: meso-α-scale cyclone on the Baiu front approaching to the Kanto District). It is noted that about half of the “heavy rainfall days” corresponded to these pattern. In other words, unlike the localized torrential rain in western Japan, the “heavy rainfall days” due to the duration of “not-so-intense-rain” appeared rather frequently in the eastern part of Japan even in the Baiu season. In both Patterns B and C, relatively strong low-level southerly wind associated with the disturbance (a typhoon or a meso-α-scale cyclone) invades into the baroclinic zone in the basic field sustained as the sowthwestern edge of the cool Okhotsk air mass. It is interesting that the “heavy rainfall days” there due to the contribution of the persistent “not-so-intense-rain” occur just in such situation. en-copyright= kn-copyright= en-aut-name=MatsumotoKengo en-aut-sei=Matsumoto en-aut-mei=Kengo kn-aut-name=松本健吾 kn-aut-sei=松本 kn-aut-mei=健吾 aut-affil-num=1 ORCID= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=2 ORCID= en-aut-name=OtaniKazuo en-aut-sei=Otani en-aut-mei=Kazuo kn-aut-name=大谷和男 kn-aut-sei=大谷 kn-aut-mei=和男 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学教育学部（理科） affil-num=2 en-affil= kn-affil=岡山大学大学院教育学研究科 affil-num=3 en-affil= kn-affil=岡山大学大学院自然系科学研究科 en-keyword=rainfall characteristics in eastern Japan kn-keyword=rainfall characteristics in eastern Japan en-keyword=heavy rainfall in eastern Japan in Baiu season kn-keyword=heavy rainfall in eastern Japan in Baiu season en-keyword=rainfall climatology kn-keyword=rainfall climatology END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=13 end-page=24 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20131227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A case study on the rainfall distribution over the Japan Islands associated with the approach of Ty0423 in late October (Comparison with that for Ty0418) kn-title=2004年10月後半の台風23号に伴う日本列島での広域の降水（台風18号と比較して） en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rainfall distribution in the Japan Islands associated with the approach of Typhoon No.23 around 20 October 2004 (referred to Ty0423, hereafter) showed considerably different features from those in late summer of this year. The present study examined the detailed rainfall features around the Japan Islands brought by Ty0423 and the atmospheric processes based on the operational observation data by the Japan Meteorological Agency (JMA), comparing with those in association with Ty0418 around 7 September 2004. During the stage when Ty0423 was approaching or landing on the western part of the Japan Islands, the areal mean precipitation from Kyushu to Kanto District attained much larger than that for Ty0418, with wider extension of the area with the large amount of precipitation. It is interesting that, although the intense rainfall was observed only at the upstream side of the mountain range from Kyushu to Honshu District for Ty0418 except for the area near its center, strong rainfall with 10~30 mm/h persisted in wider regions from the western to the eastern part of the Japan Islands, resulting in the considerably large total rainfall for Ty0423. As for the case for Ty0423, the surface front with stable frontal surface was located just to the east of the Ty0423 center just before its landing at the Japan Islands. Thus, the huge moisture inflow mainly in the eastern region from the typhoon center seems to be redistributed widely over the Japan Islands area associated with the large-scale convergence around the stable frontal surface. In late October, the colder air associated with the high pressure system in the eastern Siberia can cover the northern part of the Japan Sea area as the seasonal march. Such basic field might be favorable for sustaining the synoptic-scale front just around the southern coast of the Japan Islands, even when the strong southerly wind invades associated with the typhoon approach there. en-copyright= kn-copyright= en-aut-name=SatakeAi en-aut-sei=Satake en-aut-mei=Ai kn-aut-name=佐竹愛 kn-aut-sei=佐竹 kn-aut-mei=愛 aut-affil-num=1 ORCID= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=2 ORCID= en-aut-name=MoriYoshinori en-aut-sei=Mori en-aut-mei=Yoshinori kn-aut-name=盛宣誠 kn-aut-sei=盛 kn-aut-mei=宣誠 aut-affil-num=3 ORCID= en-aut-name=GodaYasuhiro en-aut-sei=Goda en-aut-mei=Yasuhiro kn-aut-name=合田泰弘 kn-aut-sei=合田 kn-aut-mei=泰弘 aut-affil-num=4 ORCID= en-aut-name=IkedaShoichiro en-aut-sei=Ikeda en-aut-mei=Shoichiro kn-aut-name=池田祥一郎 kn-aut-sei=池田 kn-aut-mei=祥一郎 aut-affil-num=5 ORCID= en-aut-name=TsukamotoOsamu en-aut-sei=Tsukamoto en-aut-mei=Osamu kn-aut-name=塚本修 kn-aut-sei=塚本 kn-aut-mei=修 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil=岡山大学大学院教育学研究科 affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=6 en-affil= kn-affil=岡山大学大学院自然科学研究科 en-keyword=Ty0423 kn-keyword=Ty0423 en-keyword=Ty0418 kn-keyword=Ty0418 en-keyword=rainfall in Japan associated with a typhoon in mid-autumn kn-keyword=rainfall in Japan associated with a typhoon in mid-autumn en-keyword=effects of a typhoon on the synoptic climatology in Japan in October kn-keyword=effects of a typhoon on the synoptic climatology in Japan in October END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=7 end-page=11 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20131227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=On Periploma mitsuganoense Araki (Bivalvia: Mollusca) from the Miocene Bihoku Group in Niimi City, Okayama Prefecture, southwest Japan ―with special reference to it’s paleogeographic significance― kn-title=岡山県新見市の中新世備北層群からのPeriploma mitsuganoense Araki (Bivalvia: Mollusca)について　―特にその古地理学的意義― en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, we deal with re-description of Periploma mitsuganoense Araki and it’s morphological variation and significance of the molluscan fauna of it from the Miocene Bihoku Group in Niimi City, Okayama Prefecture, Southwest Japan. Moreover, the paleogeographic significance of this species is analyzed. The obtained results are summarized as follows: 1. The morphological variation of Periploma mitsuganoense Araki has a wide range on the basis of the analysis of the morphological outline. 2. The occurrence of P. mitsuganoense Araki from the Pectinid fauna is the first record in the West Setouchi Geological Province. 3. It is presumable that P. mitsuganoense Araki is an endemic species in the First Setouchi Geological Province from a view point of it’s spatial distribution. en-copyright= kn-copyright= en-aut-name=TaguchciEiji en-aut-sei=Taguchci en-aut-mei=Eiji kn-aut-name=田口栄次 kn-aut-sei=田口 kn-aut-mei=栄次 aut-affil-num=1 ORCID= en-aut-name=KishimotoShingo en-aut-sei=Kishimoto en-aut-mei=Shingo kn-aut-name=岸本眞五 kn-aut-sei=岸本 kn-aut-mei=眞五 aut-affil-num=2 ORCID= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name=鈴木茂之 kn-aut-sei=鈴木 kn-aut-mei=茂之 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil=岡山大学理学部地球科学科 en-keyword=Periploma mitsuganoense Araki kn-keyword=Periploma mitsuganoense Araki en-keyword=Mollusca kn-keyword=Mollusca en-keyword=Miocene kn-keyword=Miocene en-keyword=Bihoku Group kn-keyword=Bihoku Group en-keyword=morphological variation kn-keyword=morphological variation en-keyword=paleogeographic significance kn-keyword=paleogeographic significance END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20131227 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Debris avalanche occurred in Kitamura area, Kurashiki City, Okayama Prefecture kn-title=岡山県倉敷市北村地域で発生した土石流災害の特徴と要因 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The debris avalanche occurred in Kitamura area, Kurashiki City, Okayama Prefecture caused by the hard rain of Typhoon 12 of September, 2011. Furthermore, 11 small landslides occurred in the study area. In this area, the altitude of mountainous are not so high (150m to 250m) and the amount of precipitation which producted the debris avalanche was not very serious quantity with 230mm. However the debris avalanche occurred. One private house collapsed, and the first floor part of the Kitamura Elementary School was buried due to the debris flow. The purpose of this study is to examine causes of the debris avalanche disaster occurred in Kitamura area using applied geological technique. The length of the debris avalanche scar is about 250m, and alluvial fan is formed as a debris slope. The ground is composed of weathered granite and the bottom of the valley was filled by soils derived from disintegrated granite. There are three small landslides as head scarps with steep slopes at approximately 30°-35°. The debris avalanche was inferred to have started as a shallow soil slip at the head by rainfall. 3 major causes are inferred which originated the debris avalanche in the study area; steep slope, ground composed of weathered granite, existence of sandy soil which occupied at the bottom of valley. en-copyright= kn-copyright= en-aut-name=KimuraYuki en-aut-sei=Kimura en-aut-mei=Yuki

kn-abstract=A case study on persistent appearance of the ensemble of precipitation bands in the warm sector of the Baiu front in Kyushu District, the western part of Japan around 19 June 2001 was performed based on the operational observational data. Around 00UTC (09JST) 19 June when the Baiu front on the surface weather map was still located about a few 100kms to the north of Kyushu, the number and the total area of the meso-β or γ-scale line-shaped precipitation bands increased around Kyushu rapidly. These precipitation bands had been sustained there and gradually gathered each other to change into the Baiu frontal precipitation zone extending from the northern Kyushu to Seto-Naikai (Seto Inland Sea) around 09UTC (18JST) 19 June (the intense rainfall zone was still located in the warm sector of the Baiu front). Until ~09UTC (18JST) 19 June, the moist air flow with the latently unstable stratification had been sustained around Kyushu corresponding to the low-level southerly wind toward the surface Baiu front to the north of Kyushu. This large-scale situation would contribute greatly to the maintenance of the ensemble of the line-shaped precipitation bands in the warm sector of the Baiu front. en-copyright= kn-copyright= en-aut-name=GodaYasuhiro en-aut-sei=Goda en-aut-mei=Yasuhiro kn-aut-name=合田泰弘 kn-aut-sei=合田 kn-aut-mei=泰弘 aut-affil-num=1 ORCID= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=2 ORCID= en-aut-name=TsukamotoOsamu en-aut-sei=Tsukamoto en-aut-mei=Osamu kn-aut-name=塚本修 kn-aut-sei=塚本 kn-aut-mei=修 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院教育学研究科自然教育学系理科教育講座 affil-num=3 en-affil= kn-affil=岡山大学大学院自然科学研究科 en-keyword=ensemble of line-shaped precipitation bands kn-keyword=ensemble of line-shaped precipitation bands en-keyword=precipitation in the warm sector of the Baiu front kn-keyword=precipitation in the warm sector of the Baiu front en-keyword=Baiu fronal rainfall kn-keyword=Baiu fronal rainfall END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=25 end-page=37 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20121226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The oldest fossil forest in Japan discovered from the Upper Triassic Nariwa Group, Okayama Prefecture, SW Japan -Implication for reconstruction of depositional environment and paleovegetation- kn-title=上部三畳系成羽層群における 日本最古の化石林の発見 ―堆積環境復元および古植生復元における意義― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Erect fossil stumps were found from the outcrop of the Upper Triassic Hinabata Formation, the uppermost part of the Nariwa Group at Hinabata, Nariwa-cho,Takahashi City, Okayama Prefecture, SW Japan.

The Upper Triassic Nariwa Group is mostly composed of non-marine deposits except the marine Jito Formation and characterized by the abundance in plant fossils. The marine Jito Formation is characterized by occurrence of Norian Monotis ochotica. On the basis of detailed observation of the occurrence of erect fossil stumps, as well as sedimentary facies of fossil-bearing unit, the fossil forest was interpreted to have grown on the top of the natural-levee units. One of the erect fossil stumps was identified as Xenoxylon sp. en-copyright= kn-copyright= en-aut-name=YukawaHirokazu en-aut-sei=Yukawa en-aut-mei=Hirokazu kn-aut-name=湯川弘一 kn-aut-sei=湯川 kn-aut-mei=弘一 aut-affil-num=1 ORCID= en-aut-name=TeradaKazuo en-aut-sei=Terada en-aut-mei=Kazuo kn-aut-name=寺田和雄 kn-aut-sei=寺田 kn-aut-mei=和雄 aut-affil-num=2 ORCID= en-aut-name=SunGe en-aut-sei=Sun en-aut-mei=Ge kn-aut-name=孫革 kn-aut-sei=孫 kn-aut-mei=革 aut-affil-num=3 ORCID= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name=鈴木茂之 kn-aut-sei=鈴木 kn-aut-mei=茂之 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil= kn-affil=福井県立恐竜博物館 affil-num=3 en-affil= kn-affil=遼寧古生物博物館 affil-num=4 en-affil= kn-affil=岡山大学大学院自然科学研究科 en-keyword=erect fossil stump kn-keyword=erect fossil stump en-keyword=fossil forest kn-keyword=fossil forest en-keyword=Nariwa Group kn-keyword=Nariwa Group en-keyword=Upper Triassic kn-keyword=Upper Triassic en-keyword=Xenoxylon kn-keyword=Xenoxylon END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=19 end-page=24 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20121226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Estimation of SPM concentration distribution over the central Seto Inland Sea kn-title=瀬戸内海中部上空におけるSPM濃度分布の推定 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ordinary Kriging, OK, and Regression Kriging, RK, are the spatial statistical methods that are possible to estimate a horizontal distribution in a study area from discrete data. OK is the method which takes account of only spatial auto-correlation structure of the data, while RK is the method which takes account of an interrelationship between spatial auto-correlation structure and some auxiliary variables to minimize the estimation error. Analytical processing for OK and RK methods was performed by the R-Language (R Core Team, 2012) and its some additional libraries. The auxiliary variables required to perform RK method were prepared by a GIS application, Quantum GIS (Quantum GIS Development Team, 2012). The 3-dimensional geographic representation of the estimation maps was performed by the Google Earth (Google, 2012). In this report, OK and RK methods were applied to one of the Earth scientific information, SPM (Supended Particulate Matter). Then, these methods were considered by comparing two estimation maps, and finally considered qualitatively by displaying these maps in the Google Earth. en-copyright= kn-copyright= en-aut-name=EbiTakahiro en-aut-sei=Ebi en-aut-mei=Takahiro kn-aut-name=海老貴宏 kn-aut-sei=海老 kn-aut-mei=貴宏 aut-affil-num=1 ORCID= en-aut-name=MatsumotoHirofumi en-aut-sei=Matsumoto en-aut-mei=Hirofumi kn-aut-name=松本宏文 kn-aut-sei=松本 kn-aut-mei=宏文 aut-affil-num=2 ORCID= en-aut-name=YamakawaJunji en-aut-sei=Yamakawa en-aut-mei=Junji kn-aut-name=山川純次 kn-aut-sei=山川 kn-aut-mei=純次 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科地球科学専攻 affil-num=2 en-affil= kn-affil=岡山大学大学院自然科学研究科地球科学専攻 affil-num=3 en-affil= kn-affil=岡山大学大学院自然科学研究科地球科学専攻 en-keyword=Ordinary Kriging kn-keyword=Ordinary Kriging en-keyword=Regression Kriging kn-keyword=Regression Kriging en-keyword=Auxiliary variable kn-keyword=Auxiliary variable en-keyword=R-Language kn-keyword=R-Language en-keyword=Google Earth kn-keyword=Google Earth END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=13 end-page=17 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20121226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The temperature and pressure conditions of synthetic Sibirskite and Parasibirskite kn-title=シベリア石とパラシベリア石の安定温度圧力条件 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sibirskite (CaHBO ) and parasibirskite ? are in the relation of polymorphism, these are regarded as the alteration products of takedaite (Ca?B?O?), occurs at Fuka mine, Okayama Prefecture. The synthesis of parasibirskite was reported by the Sch?fer (1968a, b) etc. and the synthesis of sibirskite was reported by the Sun et al. (2011). To determine the formation condition of sibirskite and parasibirskite in the natural, they were synthesized from the natural takedaite (Ca?B?O?). As a result, both of sibirskite and parasibirskite were formed by the duration time of 7 days with 1000 kg/cm2 and 300 oC, on the other hand, only sibirskite was formed by the duration time of 14 days with the same condition. In addition, the mixtures of sibirskite and parasibirskite were examined under the various temperatures and pressures of hydrothermal conditions. As a result, the upper limit of the stable temperature and pressure conditions of sibirskite was estimated between 350 oC and 400 oC at 1500 kg/cm2, and between 400 oC and 450 oC at 500 kg/cm2 .

The Nariwa Group unconformably covers the Paleozoic successions (Otoh, 1985). The Lower Carboniferous to Middle Permian Ko-yama Limestone Group, dated by foraminifers and fusulinids (Yokoyama et al., 1979), is mainly composed of massive limestone with basic volcanics, acidic tuff and chert. The Paleozoic successions of the Akiyoshi Belt were folded during the Middle to Late Permian (Suzuki et al., 1990). Strata of the Ko-yama Limestone Group generally strike E-W and dip to the north. The Hoya section about 300 m thick is composed of limestone, basic tuff, chert and acidic tuff, limestone, basic lava and tuff in ascending order. In this section, Ishida et al. (2012) recognized a nearly complete conodont faunal succession ranging from the upper Visean to the lower Moscovian. The faunal succession indicates younging southward, and the strata are overturned. A folded strucuture of tight overfold with north-dipping axial plane was reconstructed. Similar style of small scale overfolds of banded chert and turbidite were observed in the overlying Yoshii Group. en-copyright= kn-copyright= en-aut-name=InadaNoriyuki en-aut-sei=Inada en-aut-mei=Noriyuki kn-aut-name=稲田徳之 kn-aut-sei=稲田 kn-aut-mei=徳之 aut-affil-num=1 ORCID= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name=鈴木茂之 kn-aut-sei=鈴木 kn-aut-mei=茂之 aut-affil-num=2 ORCID= en-aut-name=IshidaKeisuke en-aut-sei=Ishida en-aut-mei=Keisuke kn-aut-name=石田啓祐 kn-aut-sei=石田 kn-aut-mei=啓祐 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部地球科学科 affil-num=2 en-affil= kn-affil=岡山大学理学部地球科学科 affil-num=3 en-affil= kn-affil=徳島大学大学院ソシオ・アーツ・アンド・サイエンス研究部基礎科学部門自然科学分野 en-keyword=folded structure kn-keyword=folded structure en-keyword=Ko-yama Limestone Group kn-keyword=Ko-yama Limestone Group en-keyword=Carboniferous kn-keyword=Carboniferous en-keyword=Akiyoshi Belt kn-keyword=Akiyoshi Belt END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=1 end-page=4 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20121226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Holocene environmental and sea-level changes of the Okayama Plain ? evidence from peat beds ? kn-title=岡山平野の泥炭層から推測される完新世の海水準変動と古環境変遷 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Quaternary peat beds from bore-hole samples deliver information to reconstruct paleoenvironment.

Most of particles are less than 30 μm in diameter, the greater part of particles observed at the 6 locations were considered to be transported from the Asian continent sources as Asian dust (KOSA). The variation patterns of the vertical profiles of particle concentrations in snow layers were corresponding among each location. The concentrations of particles with less than 30 μm was gradually increased with increasing distance from the Sea of Japan to the Japan Alps, although, sharply-decreased at 3 sites located the monsoon-leeward of the Japan Alps, suggesting that the particles transported with monsoon were gradually removed from air and deposited in snow cover when the air parcel pass through the Japan Alps.

kn-title=初夏に日本列島付近へ北上する台風の進路や周辺場の特徴について en-subtitle= kn-subtitle= en-abstract= kn-abstract=The number of typhoons approaching the Japan Islands is much smaller in May and June than in August to September. However, some typhoons abnormally approach to the Japan Islands in May or June as in 2004. The present study investigated the characteristics of the typhoon tracks and the large-scale fields in May and June associated with the approach of typhoons to the Japan Islands. Climatologically speaking, typhoons are generally formed in the lower latitude in May and early June, and tend to turn to ENE-ward before they reach ~ 20N in May by the upper- and middle-level westerly wind. In June, the upper-level easterly wind associated with the Tibetan high seems to prevent typhoons from approaching to the Japan Islands. However, when the cell-type subtropical high and the deep westerly trough in its western side are formed with the SW-ly from the lower to the middle latitude, a favorable situation for the northward invasion of the typhoon can be realized in May. On the other hand, the formation of the barotropic-like subtropical high to the southeast of the Japan Islands seems to enable a typhoon to approach to the Japan Islands by the S-ly wind around the subtropical high. en-copyright= kn-copyright= en-aut-name=HamamotoNatsumi en-aut-sei=Hamamoto en-aut-mei=Natsumi kn-aut-name=濱本奈津美 kn-aut-sei=濱本 kn-aut-mei=奈津美 aut-affil-num=1 ORCID= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=2 ORCID= en-aut-name=NakayamaYuuki en-aut-sei=Nakayama en-aut-mei=Yuuki kn-aut-name=中山祐貴 kn-aut-sei=中山 kn-aut-mei=祐貴 aut-affil-num=3 ORCID= en-aut-name=TsukamotoOsamu en-aut-sei=Tsukamoto en-aut-mei=Osamu kn-aut-name=塚本修 kn-aut-sei=塚本 kn-aut-mei=修 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil=岡山大学大学院教育学研究科自然教育学系理科教育講座 affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil=岡山大学大学院環境学研究科 en-keyword=typhoon tracks in early summer kn-keyword=typhoon tracks in early summer en-keyword=large-scale atmospheric fields in early summer kn-keyword=large-scale atmospheric fields in early summer END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=5 end-page=10 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20111226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Newly proposed landform division in the Kibi Plateau area: Application for a hazard map of landslides kn-title=岡山市北部吉備高原地域における地形区分―斜面防災のための試み― en-subtitle= kn-subtitle= en-abstract= kn-abstract=The Kibi Plateau is characterized by horizontal skylines and they are considered to be an uplifted peneplain.

The steep slope of the recent dissecting landform is unstable and a potential of landslide is high. en-copyright= kn-copyright= en-aut-name=SuzukiShigeyuki en-aut-sei=Suzuki en-aut-mei=Shigeyuki kn-aut-name=鈴木茂之 kn-aut-sei=鈴木 kn-aut-mei=茂之 aut-affil-num=1 ORCID= en-aut-name=OmizoYuna en-aut-sei=Omizo en-aut-mei=Yuna kn-aut-name=大溝佑奈 kn-aut-sei=大溝 kn-aut-mei=佑奈 aut-affil-num=2 ORCID= en-aut-name=HirataMinoru en-aut-sei=Hirata en-aut-mei=Minoru kn-aut-name=平田稔 kn-aut-sei=平田 kn-aut-mei=稔 aut-affil-num=3 ORCID= en-aut-name=NishigakiMakoto en-aut-sei=Nishigaki en-aut-mei=Makoto kn-aut-name=西垣誠 kn-aut-sei=西垣 kn-aut-mei=誠 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院自然科学研究科 affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil=岡山大学大学院環境学研究科 en-keyword=Kibi Plateau kn-keyword=Kibi Plateau en-keyword=landslide kn-keyword=landslide en-keyword=knick-point kn-keyword=knick-point en-keyword=Okayama Prefecture kn-keyword=Okayama Prefecture END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=1 end-page=3 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20111226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=KED estimated distribution of Earth Scientific Information kn-title=KED法を用いた地球科学情報の分布推定 en-subtitle= kn-subtitle= en-abstract= kn-abstract=KED, the Kriging with External Drift, is one of the spatial statistical method for estimating some distribution from the discrete spatial sampled data set about the research field. The KED uses the kriging method (Matheron, 1973) with some auxiliary map to minimize the estimated error. The KED procedure was performed by the R-Language (Ihaka and Gentleman, 1996) using some geostatistical libraries. The auxiliary maps required by the KED were prepared by the authors with some GIS applications. The 3-dimensional geographic representations for the estimated distribution were performed by the Google Earth (Google, 2011). In this report, the KED was applied to some Earth scientific information to show the fundamental scheme of the method. en-copyright= kn-copyright= en-aut-name=YamakawaJunji en-aut-sei=Yamakawa en-aut-mei=Junji kn-aut-name=山川純次 kn-aut-sei=山川 kn-aut-mei=純次 aut-affil-num=1 ORCID= en-aut-name=EbiTakahiro en-aut-sei=Ebi en-aut-mei=Takahiro kn-aut-name=海老貴宏 kn-aut-sei=海老 kn-aut-mei=貴宏 aut-affil-num=2 ORCID= en-aut-name=MatsumotoHirofumi en-aut-sei=Matsumoto en-aut-mei=Hirofumi kn-aut-name=松本宏文 kn-aut-sei=松本 kn-aut-mei=宏文 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部地球科学科 affil-num=2 en-affil= kn-affil=岡山大学理学部地球科学科 affil-num=3 en-affil= kn-affil=岡山大学理学部地球科学科 en-keyword=KED kn-keyword=KED en-keyword=Universal kriging kn-keyword=Universal kriging en-keyword=Regression kriging kn-keyword=Regression kriging en-keyword=R-Language kn-keyword=R-Language en-keyword=Google Earth kn-keyword=Google Earth END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20111226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Title Page en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20111226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue= article-no= start-page=3 end-page=7 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=201105 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Physiological Features of the Mouse Deer -

While the Akisame frontal zone extended zonally and the deep convective clouds tended to appear in that frontal zone near the southern coast of the Japan Islands in 1993, the frontal zone extends from southwest to northeast and the large amount of precipitation was brought mainly in the northern Japan. In 1995, although the surface front on the weather maps appeared frequently also around the southern coast of the Japan Islands, the rainfall amount there was not so large. The area with frequent appearance of the deep convective clouds in the Akisame frontal zone was seen only to the east of the Japan Islands. As such, it is noted that the active area of the Akisame frontal zone shows rather large year-to-year variability also in the zonal direction. It is also suggested that such great variability of the Akisame frontal zone in the zonal direction seems to correspond to the variations of the subtropical high and the ITCZ in the western Pacific region around September. en-copyright= kn-copyright= en-aut-name=FukudaShigeko en-aut-sei=Fukuda en-aut-mei=Shigeko kn-aut-name=福田維子 kn-aut-sei=福田 kn-aut-mei=維子 aut-affil-num=1 ORCID= en-aut-name=KatoKuranoshin en-aut-sei=Kato en-aut-mei=Kuranoshin kn-aut-name=加藤内藏進 kn-aut-sei=加藤 kn-aut-mei=内藏進 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学教育学部理科教室 affil-num=2 en-affil= kn-affil=岡山大学大学院教育学研究科自然教育学系理科教育講座 en-keyword=Akisame (autumn rainfall) front kn-keyword=Akisame (autumn rainfall) front en-keyword=STFZ in early autumn kn-keyword=STFZ in early autumn en-keyword=year-to-year difference of Akisame front kn-keyword=year-to-year difference of Akisame front END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=1 end-page=5 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20101224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=西南日本の熱変成超苦鉄質岩体中のかんらん石と輝石の組成変化に関する覚書 kn-title=A note on compositional variation of olivine and pyroxene in thermally metamorphosed ultramafic complexes from SW Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=This short article presents some diagrams showing the compositional variations of primary and metamorphic olivine, orthopyroxene and clinopyroxene in peridotites and serpentinites from thermally metamorphosed ultramafic complexes in SW Japan. In contrast to olivine, which shows a gradual change of chemical composition corresponding with metamorphic grade, orthopyroxene and clinopyroxene show clear differences in composition between primary and metamorphic phases. Compared with primary pyroxenes, even though their compositions could be variable depending on original rock composition, metamorphic orthopyroxene and metamorphic clinopyroxene is clearly deficient in Cr(2)O(3) and CaO, and in Cr(2)O(3) and Al(2)O(3), respectively. These characteristics are useful for the discrimination between the pyroxenes of different origin. en-copyright= kn-copyright= en-aut-name=NozakaToshio en-aut-sei=Nozaka en-aut-mei=Toshio kn-aut-name=野坂俊夫 kn-aut-sei=野坂 kn-aut-mei=俊夫 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=Department of Earth Sciences, Faculty of Science, Okayama University en-keyword=chemical composition kn-keyword=chemical composition en-keyword=olivine kn-keyword=olivine en-keyword=orthopyroxene kn-keyword=orthopyroxene en-keyword=clinopyroxene kn-keyword=clinopyroxene en-keyword=metaperidotite kn-keyword=metaperidotite END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20101224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Title Page en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20101224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙・英文目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=裏表紙・目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-sei=Department of Earth Sciences, Faculty of Science, Okayama University en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=9-2 article-no= start-page=5947 end-page=5954 dt-received= dt-revised= dt-accepted= dt-pub-year=1959 dt-pub=19590910 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Behavior of Fluorine for Animal Organs Part 3.

It was investigated how much fluorine was accumulated in their bones and organs, when NaF, CaCO(3)+NaF, and AlK(SO(4))(2)+NaF were respectively administered to them. (1) Amounts of fluorine contained in organs of non administered rabbits were considered to be the physiological required amounts which was taken as food from natural source. (2) When 1 mg/kg, and 10 mg/kg of NaF were respectively administered. amounts of fluorine in bones and organs did not increase so remarkably, but when 20 mg/kg of NaF, fluorine contents increased suddenly in all bones and organs. (3) When both CaCO(3) and NaF were administered in the same amount of fluorine, fluorine was much more accumulated in bones and less in all organs than when NaF alone was administered.

A new reagent "Nen-Thorin" (2-(1, 8-dihydroxy-3, 6-disulfo-2-naphthylazo)-benzene arsonic acid) (max. absorption, 500 mμ in an aq. solution of pH 2.3) was synthesised and complex of this reagent with thorium (max. absorption, 570 mμ at pH 2.3) was studied for the determination of F (<50 γ in 50 ml). The extinctions of both Neo-Thorin and its complex with Th are sensitive towards change in pH, but remain constant between pH 2.1 and 2.4, the extinction of the complex decreasing in proportion to the amount of F(-). Common ions, including Cl(-), SO(4)(2-), PO(4)(3-), Al(3+), Fe(3+), Ca(2+), and Mg(2+), interefere. Any F in the sample is distilled from an H(2)SO(4) soln. in the presence of SiO(2). (1) By using the Thorium-Neo-Thorin method, small amounts of fluorine may be easily determined. Color of this reagent changes from red to purple with small amounts of fluorine ion. So that the visual qualitative test for flurorine possible. Realisable limit of fluorine is 1/100 p. p. m. (2) After the plant tissue was mixed with CaO (3% by weight of dry sample) and a small amount of water, it was evaporated to dryness and the volatile matter was expelled at 250 to 300°C and then ignited at 650°C. Maximum recovery of fluorine was 98.5%. (3) A small amount of fluorine in animal tissue was satisfactory determined by the same procedure as in plant tissue. Namely, the sample was calcinated with CaO in proportion of 15 to 20% by weight of dry sample, charred at 350 to 400°C and ignited at 750°C. Maximum recovery of fluorine was 98.93%. en-copyright= kn-copyright= en-aut-name=HayamiTadashi en-aut-sei=Hayami en-aut-mei=Tadashi kn-aut-name=速水〓 kn-aut-sei=速水 kn-aut-mei=〓 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部化学教室 END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue=1-2 article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=1989 dt-pub=198902 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Radiosensitivity of an isolated human malignant fibrous histiocytoma cell line kn-title=組織培養による人癌細胞（悪性線維性組織球腫）の放射線に対する感受性―その1― en-subtitle= kn-subtitle= en-abstract= kn-abstract=A human cell line (YU-137) isolated from a bone of malignant fibrous histiocytoma in bone was evaluated using immunofluorescent staining methods.

From these data, the radiosensitivity of YU-137 was discussed. en-copyright= kn-copyright= en-aut-name=KawasakiShoji en-aut-sei=Kawasaki en-aut-mei=Shoji kn-aut-name=川崎祥二 kn-aut-sei=川崎 kn-aut-mei=祥二 aut-affil-num=1 ORCID= en-aut-name=MizutaAkifumi en-aut-sei=Mizuta en-aut-mei=Akifumi kn-aut-name=水田昭文 kn-aut-sei=水田 kn-aut-mei=昭文 aut-affil-num=2 ORCID= en-aut-name=KashitaniNaoko en-aut-sei=Kashitani en-aut-mei=Naoko kn-aut-name=柏谷尚子 kn-aut-sei=柏谷 kn-aut-mei=尚子 aut-affil-num=3 ORCID= en-aut-name=KurodaMasahiro en-aut-sei=Kuroda en-aut-mei=Masahiro kn-aut-name=黒田昌宏 kn-aut-sei=黒田 kn-aut-mei=昌宏 aut-affil-num=4 ORCID= en-aut-name=HirakiYoshio en-aut-sei=Hiraki en-aut-mei=Yoshio kn-aut-name=平木祥夫 kn-aut-sei=平木 kn-aut-mei=祥夫 aut-affil-num=5 ORCID= en-aut-name=AonoKaname en-aut-sei=Aono en-aut-mei=Kaname kn-aut-name=青野要 kn-aut-sei=青野 kn-aut-mei=要 aut-affil-num=6 ORCID= en-aut-name=SatoJiro en-aut-sei=Sato en-aut-mei=Jiro kn-aut-name=佐藤二郎 kn-aut-sei=佐藤 kn-aut-mei=二郎 aut-affil-num=7 ORCID= en-aut-name=OginoTetsuro en-aut-sei=Ogino en-aut-mei=Tetsuro kn-aut-name=荻野哲朗 kn-aut-sei=荻野 kn-aut-mei=哲朗 aut-affil-num=8 ORCID= en-aut-name=NakanishiTakashi en-aut-sei=Nakanishi en-aut-mei=Takashi kn-aut-name=中西敬 kn-aut-sei=中西 kn-aut-mei=敬 aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医療技術短期大学部 affil-num=2 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=3 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=4 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=5 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=6 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=7 en-affil= kn-affil=岡山大学医学部癌源研究施設病理学部門 affil-num=8 en-affil= kn-affil=香川医科大学病院病理部 affil-num=9 en-affil= kn-affil=山口大学医学部放射線医学教室 en-keyword=Tissue culture kn-keyword=Tissue culture en-keyword=Malignant fibrous histeocytoma kn-keyword=Malignant fibrous histeocytoma en-keyword=Radiosensitivity kn-keyword=Radiosensitivity en-keyword=Flow cytometry kn-keyword=Flow cytometry END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue= article-no= start-page=5 end-page=8 dt-received= dt-revised= dt-accepted= dt-pub-year=1953 dt-pub=195312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ON THE EXISTENCE OF RADIUM B, RADIUM C AND THORIUM B IN MISASA HOT SPRINGS kn-title=鳥取県三朝温泉に於ける二，三の放射性元素の存在について en-subtitle= kn-subtitle= en-abstract= kn-abstract=The author tried to measure RaB, RaC and ThB in the hot spring waters using G-M counter and proved the existence of RaB and ThB in Misasa Hot Springs. To 100 liters of spring water ahout 20 gms of ferric chloride and then sodium hydroxide were added. Precipitate was dissolved in hydrochloric acid and after adding bismuth and lead, the solution was saturated with hydrogen sulfide. The precipitate of sulfides was filtered and ignited to ashes after drying. The β-activity of the ashes was measured by a mica-window type G-M counter with the recording circuits of scale of 16. Natural background was 50±5 connts per minutes. Six spring waters of Misasa, namely "Spring of Branch Laboratory", "Nakayu", "Gunze" "O-T-R", "Jwayu", and "Tsukiminoyu" were investigated. RaB was detected in all samples. ThB was found only in "Gunze" and "O-T-R". ThB content of "Gunze" was estimated, to be roughly 1×10(-12) Curie units per liter. en-copyright= kn-copyright= en-aut-name=SatoMitsuo en-aut-sei=Sato en-aut-mei=Mitsuo kn-aut-name=佐藤三雄 kn-aut-sei=佐藤

from the District of San-in (Part I) kn-title=花崗岩に関する諸問題　（8）　山陰地方産花崗岩質岩石について（第1報） en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, the petrology of the granitic rocks from the district of San-in, especially from the province of Izumo, is described with some references on the mineral resources associated in these rocks. The granitic ro:ks of which the Chugoku-Mountainland in the Izumo province is mainly composed may be classified mineralogically and chemically into next seven kinds. Their names and the respective average silica contents are as follows: (1) Hornblende-biotite granodiorite?????????SiO(2) 66.18% (2) Hornblende-biotite granite????????? SiO(2) 69.28% (3) Biotite granite?????????SiO(2) 74.91% (4) Fine-grained biotite granite and biotite granite porphyry?????????SiO(2) 73.47% (5) Aplite ?????????SiO(2) 75.96% (6) Gabbro and diorite?????????SiO(2) 56.05% (7) Quartz porphyry? ?SiO(2) 73.79% Among the various mineral resources found in the granitic rocks in this region, the iron sand and the molybdenum ore seem to have more ecconomical value and are indeed wrought respectively in several localities in farely large scale. The iron sand is collected either from the decomposition product of the hornblendebiotite granite (2) and from that of the diorite (6). The former, so-called "Masa", is superior in quality for the production of steel, but it is inferior in its quantity. On the other hand, the latter, so-called "Akome", can be gathered in quantity in larger amount than the former, but it is inferior to the former in quality. For this reason, both sorts of sand are in practice mixed in some definite amounts. The ore deposits of molybdenite contained in the quartz vein traversing the granitic rocks are found in several localities and some of them are wrought. In such cases the parent rock of the ore seems to be invariably confined to the rock type of the fine-grained biotite granite or of the aplite. Besides the rocks stated above, some descriptions are given to the rocks, such as quartz porphyry and basalt, which are found in several places in the granite region. However they seem to have no genetic relation with the underlying granites. en-copyright= kn-copyright= en-aut-name=YamaguchiKenji en-aut-sei=Yamaguchi en-aut-mei=Kenji kn-aut-name=山口鎌次 kn-aut-sei=山口 kn-aut-mei=鎌次 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=島根大学文理学部地学教室 END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue= article-no= start-page=27 end-page=32 dt-received= dt-revised= dt-accepted= dt-pub-year=1957 dt-pub=195709 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=花崗岩に関する諸問題　（6）　北九州新白亜紀花崗岩類の進化とジルコン en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=冨田達 kn-aut-sei=冨田 kn-aut-mei=達 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=唐木田芳文 kn-aut-sei=唐木田 kn-aut-mei=芳文 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=桃井斉 kn-aut-sei=桃井 kn-aut-mei=斉 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=九州大学理学部地質学教室 affil-num=2 en-affil= kn-affil=九州大学理学部地質学教室 affil-num=3 en-affil= kn-affil=九州大学理学部地質学教室 END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue= article-no= start-page=16 end-page=26 dt-received= dt-revised= dt-accepted= dt-pub-year=1957 dt-pub=195709 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=花崗岩に関する諸問題　（5）　日本花崗岩類のRa含有量および岩漿進化におけるU, Thの行動 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=冨田達 kn-aut-sei=冨田 kn-aut-mei=達 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=桃井斉 kn-aut-sei=桃井 kn-aut-mei=斉 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=唐木田芳文 kn-aut-sei=唐木田 kn-aut-mei=芳文 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=九州大学理学部地質学教室 affil-num=2 en-affil= kn-affil=九州大学理学部地質学教室 affil-num=3 en-affil= kn-affil=九州大学理学部地質学教室 END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue= article-no= start-page=9 end-page=15 dt-received= dt-revised= dt-accepted= dt-pub-year=1957 dt-pub=195709 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=花崗岩に関する諸問題　（4）　花崗岩中の放射能分布 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=初田甚一郎 kn-aut-sei=初田 kn-aut-mei=甚一郎 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=尹一 kn-aut-sei=尹 kn-aut-mei=一 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=京都大学理学部地質学鉱物学教室 affil-num=2 en-affil= kn-affil=京都大学理学部地質学鉱物学教室 END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue= article-no= start-page=7 end-page=8 dt-received= dt-revised= dt-accepted= dt-pub-year=1957 dt-pub=195709 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=花崗岩に関する諸問題　（3）　広島･島根県下花崗岩類の時代に関する資料 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=吉田博直 kn-aut-sei=吉田 kn-aut-mei=博直 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=小島丈児 kn-aut-sei=小島 kn-aut-mei=丈児 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=広島大学理学部地質学鉱物学教室 affil-num=2 en-affil= kn-affil=広島大学理学部地質学鉱物学教室 END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue= article-no= start-page=37 end-page=40 dt-received= dt-revised= dt-accepted= dt-pub-year=1966 dt-pub=19661025 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The determination of copper and zinc in W-1 by the atomic absorption flame photometry kn-title=原子吸収炎光光度法による標準岩石試料W -1中の銅および亜鉛の予備的定量 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Copper and zinc in W-1 have been determined using a Jarrell-Ash Model 82-360 atomic absorption flame photometer.

The reproducibility of δ(13)C measurement is about ±0.2‰. Some systematic differences in δ(18)O values were observed among the three measurements in Apr.-May, July, and Aug., 1971. Because these systematic differences are supposed to be caused by the imperfection in the processes of decomposition of carbonates by phosphoric acid, the reproducibility of δ(18)O measurement may be ±O.2‰ in most cases. The calibrations of our working standard, CK-13, against the PDB standard were carried out on the assumption that δ(18)O and δ(13)C of CK-13 are -1.75‰ and +O.54‰ relative to PDB, respectively. The accuracy of these calibrations is about ±O.2‰ as shown by the interlaboratory comparison of some standards (Table 3). The δ(18)O values of the two working standards relative to PDB are independently recalculated relative to SMOW based on the two assumptions (Table 4). One of which is that a standard water MSA-2 is -8.20‰ relative to SMOW, and the other is that the δ(18)O of CK-13 is -1.75‰ relative to PDB. The results of both calculations agree within 0.4‰. en-copyright= kn-copyright= en-aut-name=WatanabeMakoto en-aut-sei=Watanabe en-aut-mei=Makoto kn-aut-name=渡辺洵 kn-aut-sei=渡辺 kn-aut-mei=洵 aut-affil-num=1 ORCID= en-aut-name=MatsubayaOsamu en-aut-sei=Matsubaya en-aut-mei=Osamu kn-aut-name=松葉谷治 kn-aut-sei=松葉谷 kn-aut-mei=治 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=東京大学理学部地質学教室 affil-num=2 en-affil= kn-affil=岡山大学温泉研究所温泉化学部門 END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue= article-no= start-page=1 end-page=13 dt-received= dt-revised= dt-accepted= dt-pub-year=1974 dt-pub=19740325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Phlogopites and coexisting pargasites in wehrlite from the northern Kanto mountains, central Japan kn-title=北関東山地,単斜輝石かんらん岩の金雲母とパーガス閃石 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Coexisting interstitial phlogopites and pargasites in iron rich wehrlite from the northern Kanto mountains were studied. The textural relationｓ between those interstitial hydrous minerals and major constituent minerals, such as olivines and clinopyroxenes suggest the crystallization of the former from the intergranular residual liquids. The modal amounts of phlogopites in wehrlite are less than 1%, and that of pargasites range from 2 to 5%. Microprobe analyses have been carried for those hydrous minerals and the major constituent minerals. namely, olivine, clinopyroxene and idiomorphic zoned chromite. Olivines in wehrlite from the northern Kanto mountains have rather iron-rich nature and range from Foso to Fo(80) and those coexisting with the hydrous minerals are Fo(82.5) in average. Clinopyroxenes from mica bearing wehrlite contain about 2.5% Al(2)O(3). 17% MgO and 5.5% FeO. Tentative cation per cent of Ca, Mg and Fe are calculated as Ca(42.6) Mg(48.1) Fe(9.3) in average. The present probe analyses show high magnesian nature of the interstitial phlogopites. In addition, these phlogopites are conspicuous by their high TiO(2) content ranging from 4.6 to 5.2%. Mg/Mg + Fe versus Ti relation plotted in Fig. 4 revealed that the present phlogopite are similar to that of the alkaline pyroxenite nodules from the Lashaine volcano, northern Tanzania. Pargasites in mica bearing wehrlite are also rich in TiO(2) (3.0〜4.7%), whereas pargasitic common hornblende from hornblendite or gabbro are rather low in TiO(2) (0.9〜1.7%). Mg/Mg+Fe+Mn versus Ti relations of amphiboles illustrate that Ti contents increase with decrease of Mg/Mg+Fe +Mn. Two different increasing trend for Ti conten t are also noticed. Idiomorphic chromites show distinct compositional variation from core to rim. Total FeO increases about 16% at rim, whereas TiO(2), Al(2)O(3) and MgO decrease at the rim. Possible crystallization scheme of those hydrous minersls is proposed in Fig. 10, where the maximum stability limits of phlogopite and hornblende are shown with the curve for begining of melting of basalt. Separation of liquid fraction from cumulate phase with a small trapped intergranular liquid might occur at point A. The liquid fraction then might move upward through the course II. In cumulate phase, intergranular liquid might crystallize pargasitic amphibole by the reaction with olivine and clinopyroxene through the course I in Fig. 10. Intergranular liquid might decrease with production of amphiboles and K(2)O might concentrate in residual liquid. At final stage of crystallization, residual liquid rich in K(2)O might crystallize as phlogopite by the reactions with olivine. Decrease of Ti02 content at the nm of idiomorphic chromite might be related to the formations of Ti-rich hydrous minerals. en-copyright= kn-copyright= en-aut-name=TazakiKoichi en-aut-sei=Tazaki en-aut-mei=Koichi kn-aut-name=田崎耕市 kn-aut-sei=田崎 kn-aut-mei=耕市 aut-affil-num=1 ORCID= en-aut-name=InomataMichiya en-aut-sei=Inomata en-aut-mei=Michiya kn-aut-name=猪俣道也 kn-aut-sei=猪俣 kn-aut-mei=道也 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所 affil-num=2 en-affil= kn-affil=東京教育大学理学部地質学鉱物学教室 END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue= article-no= start-page=7 end-page=20 dt-received= dt-revised= dt-accepted= dt-pub-year=1975 dt-pub=19750325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Semi-automatic processing of EPMA data kn-title=EPMA DATA 処理の半自動化の試み en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KawasakiToshisuke en-aut-sei=Kawasaki en-aut-mei=Toshisuke kn-aut-name=川嵜智佑 kn-aut-sei=川嵜 kn-aut-mei=智佑 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=京都大学理学部地鉱教室 END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue= article-no= start-page=15 end-page=28 dt-received= dt-revised= dt-accepted= dt-pub-year=1974 dt-pub=19740325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Hydrogen and oxygen isotopic ratios of thermal and mineral springs in Arima area kn-title=有馬地域の温泉,鉱泉の水素と酸素の同位体比について en-subtitle= kn-subtitle= en-abstract= kn-abstract=Saline waters of thermal and mineral springs in Arima area, at Takarazuka, and in Ishibotoke area of Kawachinagano City indicate wide ranges of δD and δ(18)O values (Table 1). Excellent linearity exists between the δD and δ(18)O values (Fig. 1) and between the δ(18)O value and the chloride concentration (Fig. 2). These facts as well as the chemical evidence of the previous investigators strongly support the view that Arima springs are admixtures of a single deep brine and local ground water (TSURUMAKI, 1964). The deep brine may have the δ(18)O value of +8.0〜+8.5‰, the δD value of -25〜-30‰, and the chloride concentration of 1.20〜1.25 eq/l, which were estimated from the water of the maximum salinity so far reported. Because the thermal and mineral springs in Arima area closely associate with the upper Cretaceous granitic rocks, and the estimated δ(18)O value of the deep brine is similar to a value of water in isotopic equilibrium with those granitic rocks at 500〜600℃, the deep brine of Arima might have been the magmatic water of those granitic rocks. The mineral springs at Takarazuka and in Ishibotoke area also show the similar linearity among Cl(-), δ(18)O and δD to those in Arima area. Therefore it is assumed that the mineral springs at Takarazuka may be of the same origin as that in Arima area, and the mineral springs in Ishibotoke area might have been the fluid associated with Ryoke metamorphic rocks. Alternatively, the deep brine in Arima area may be isotopically and chemically similar to the saline formation waters in Illinois basin (GRAF et al., 1966). The high δD values and salinities of those formation waters were attributed to the isotopic and chemical fractionation during the passage of water through sediments. The deep brine in Arima area may be genetically similar to those saline formation waters. If such a saline water could have formed in Osaka basin, it is not surprising to find out the similar brines at Arima and Ishibotoke which are the northwestern and southeastern rims of the basin, respectively. At the present, it cannot be answered which of these two models is more probable. Further studies on other saline springs fluid inclusions of Cretaceous granitic rocks may be useful in order to solve this problem. en-copyright= kn-copyright= en-aut-name=MatsubayaOsamu en-aut-sei=Matsubaya en-aut-mei=Osamu kn-aut-name=松葉谷治 kn-aut-sei=松葉谷 kn-aut-mei=治 aut-affil-num=1 ORCID= en-aut-name=SakaiHitoshi en-aut-sei=Sakai en-aut-mei=Hitoshi kn-aut-name=酒井均 kn-aut-sei=酒井 kn-aut-mei=均 aut-affil-num=2 ORCID= en-aut-name=TsurumakiMichiji en-aut-sei=Tsurumaki en-aut-mei=Michiji kn-aut-name=鶴巻道二 kn-aut-sei=鶴巻 kn-aut-mei=道二 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所化学部門 affil-num=2 en-affil= kn-affil=岡山大学温泉研究所化学部門 affil-num=3 en-affil= kn-affil=大阪市立大学理学部地学教室 END start-ver=1.4 cd-journal=joma no-vol=50 cd-vols= no-issue= article-no= start-page=17 end-page=24 dt-received= dt-revised= dt-accepted= dt-pub-year=1980 dt-pub=19800325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=An isotope study of hot springs in Nagano Prefecture kn-title=長野県の温泉についての同位体化学的調査報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Water samples from 28 hotsprings and mineral springs in Nagano Prefecture, central Japan, were examined for their stable isotope ratios of hydrogen, oxygen, carbon, and sulfur. Spring waters of Kashio are highly saline and enriched in heavy isotopes of oxygen and hydrogen (δ(18)O=-2.5〜-4.6‰, δD=-54〜-57‰). Linear relationships among δD, δ(18)O, and Cl(-) suggest that spring waters are the mixtures of a deep brine and local surface water. Extrapolation of the linear relationships indicates that the deep brine is both isotopically and chemically very similar to the deep brine previously suggested for the springs of Arima, Takarazuka, and Ishibotoke of which δD, δ(18)O, and Cl(-) are estimated as -33‰, +8.0‰, and 44g/l, respectively. A common origin may be warranted among these postulated brines, while their provenance is yet to be worked out. The hot springs in Matsushiro are a Na-Ca-Cl type of high carbonate content. Their hydrogen and oxygen isotope ratios (δD=-71〜-46‰, δ(18)O=-9.1〜-2.0‰) are higher than the local surface water. On the basis of the relationships among δD, δ(18)O, and Cl(-), they are considered to be the mixtures of fossil sea water and certain water of meteoric origin of which Cl(-) is about 4g/l and δ(18)O is higher by about 3‰ than the local surface water. The latter may be meteoric water circulating in the marine sedimentary formations (Green Tuff formations) with soluble sea salts. Isotopic exchange with carbonate minerals in the formations explains its (18)O enrichment. Spring waters from Yashio and Isobe (Gunma Pref.) as well as Yunosawa and Yatate (Akita Pref.) were previously interpreted to be mixtures of fossil sea water and local surface water of low Cl(-) content. Re-examination of their data revealed that the meteoric waters responsible for these springs contain about 3g/l Cl(-), similar to the value obtained for Matsushiro. However, unlike Matsushiro, the meteoric waters in these areas are found to be isotopically similar to the local surface waters. Waters from other hot springs studied here are of simply meteoric origin, thus belonging to the GreenTuff type water previously defined. en-copyright= kn-copyright= en-aut-name=MatsubayaOsamu en-aut-sei=Matsubaya en-aut-mei=Osamu kn-aut-name=松葉谷治 kn-aut-sei=松葉谷 kn-aut-mei=治 aut-affil-num=1 ORCID= en-aut-name=SakaiHitoshi en-aut-sei=Sakai en-aut-mei=Hitoshi kn-aut-name=酒井均 kn-aut-sei=酒井 kn-aut-mei=均 aut-affil-num=2 ORCID= en-aut-name=KusakabeMinoru en-aut-sei=Kusakabe en-aut-mei=Minoru kn-aut-name=日下部実 kn-aut-sei=日下部 kn-aut-mei=実 aut-affil-num=3 ORCID= en-aut-name=SasakiAkira en-aut-sei=Sasaki en-aut-mei=Akira kn-aut-name=佐々木昭 kn-aut-sei=佐々木 kn-aut-mei=昭 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所熱水地球化学部門 affil-num=2 en-affil= kn-affil=岡山大学温泉研究所熱水地球化学部門 affil-num=3 en-affil= kn-affil=富山大学理学部地球科学科 affil-num=4 en-affil= kn-affil=地質調査所鉱床部 END start-ver=1.4 cd-journal=joma no-vol=54 cd-vols= no-issue= article-no= start-page=43 end-page=53 dt-received= dt-revised= dt-accepted= dt-pub-year=1984 dt-pub=19840325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Relict igneous minerals of the Sangun metamorphic rocks of the Tsuboi district, Okayama Prefecture kn-title=岡山県久米郡坪井地域の三部変成岩類の残存火成鉱物 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The Sangun metamorphic rocks of the Maniwa Group are well developed in the Tsuboi district, Okayama Prefecture. These metamorphic rocks consist mainly of psammitic and pelitic sedimentary rocks and lavas and pyroclastics of basic to acidic compositions that recrystallized during the Sangun low-grade regional metamorphism. The metamorphic rocks in this district underwent to a considerable extent a mineralogical and textural transformation, but still preserve in parts their original, mineralogical and textural features. Unaltered, relict clinopyroxenes and hornblendes are commonly observed in the metamorphic rocks derived from basic lavas and intermediate pyroclastics. Microprobe analyses of these relict minerals suggest that their host rocks were probably derivatives of magma(s) with a non-alkaline affinity. en-copyright= kn-copyright= en-aut-name=LiQing-Yi

kn-subtitle= en-abstract= kn-abstract=Monitoring of environmental ionizing radiation and radioisotopes in Okayama city and the vicinity was carried out from the point of view of the external radiation from the environmental radiation dose. Although the fluctuation of monthly detected radiation dose throughout the year was rather low at each observation point, the mean value of dose equivalent was varied between the place of observation. From the observation of the distribution of environmental radiation dose in Okayama city, it was assumed that its distribution was well corresponded with the distribution of igneous rocks. The concentrations of radioisotopes in various kinds of rocks corrected in Okayama city and its vicinity were determined. It became apparent that high concentrations of radioisotopes, such as (134)Cs, (40)K, (226)Ra and (228)Th, were detected in igneous rocks, such as granite, gabbro and rhyolitic tuff, although the contents in sedimentary rocks, such as pelite, schist, psammite and limestone, were rather low. This result was in good agreement with that of the distribution of radiation dose in Okayama city. en-copyright= kn-copyright= en-aut-name=MioMitsunobu en-aut-sei=Mio en-aut-mei=Mitsunobu kn-aut-name=見尾光庸 kn-aut-sei=見尾 kn-aut-mei=光庸 aut-affil-num=1 ORCID= en-aut-name=KanayamaMunetoshi en-aut-sei=Kanayama en-aut-mei=Munetoshi kn-aut-name=鑛山宗利 kn-aut-sei=鑛山 kn-aut-mei=宗利 aut-affil-num=2 ORCID= en-aut-name=TadaMikiro en-aut-sei=Tada en-aut-mei=Mikiro kn-aut-name=多田幹郎 kn-aut-sei=多田 kn-aut-mei=幹郎 aut-affil-num=3 ORCID= en-aut-name=OnoBun-ichiro en-aut-sei=Ono en-aut-mei=Bun-ichiro kn-aut-name=小野文一郎 kn-aut-sei=小野 kn-aut-mei=文一郎 aut-affil-num=4 ORCID= en-aut-name=HachiyaKinji en-aut-sei=Hachiya en-aut-mei=Kinji kn-aut-name=蜂谷欽司 kn-aut-sei=蜂谷 kn-aut-mei=欽司 aut-affil-num=5 ORCID= en-aut-name=SatohKimiyuki en-aut-sei=Satoh en-aut-mei=Kimiyuki kn-aut-name=佐藤公行 kn-aut-sei=佐藤 kn-aut-mei=公行 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学薬学部 affil-num=2 en-affil= kn-affil=岡山大学RI共同利用津島施設 affil-num=3 en-affil= kn-affil=岡山大学農学部 affil-num=4 en-affil= kn-affil=岡山大学薬学部 affil-num=5 en-affil= kn-affil=岡山大学RI共同利用津島施設 affil-num=6 en-affil= kn-affil=岡山大学理学部 END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue= article-no= start-page=56 end-page=62 dt-received= dt-revised= dt-accepted= dt-pub-year=1995 dt-pub=19951220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Determination of Inorganic Anions in Environmental Samples by Capillary Electrophoresis kn-title=環境汚染による人体への影響の定量的評価―環境疫学の概念と最近の話題― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Concept and recent topics on environmental epidemiology have been introduced in the article.

In this study, the use of a polymer coated silica capillary and an anionic organic photometric reagent realized a stable baseline and short analytical time. Nine kinds of anions, Cl(-), Br(-), NO(3)(-), SO(4)(2-), C(2)O(4)(2-), ClO(4)(-), F(-), HPO(4)(2-), and HCO(3)(-), were well separated and detected within 12 minutes. Calibration graphs for the anions showed a good linearity in the range of 0 to 4x10(-4) mol dm(-3). Detection limits of the anions were 2x10(-6) mol dm(-3) (HPO(4)(2-)) to 4x10(-5) mol dm(-3) (NO(2)(-)). Anions in river water (Zasu river) and waste water (Okayama University, North district) were measured over 5 days. The waste water contained various kinds of anions, at high concentrations with its large variation, when compared with the river water. The proposed method offers a simple, rapid, and accurate analysis of anions in water samples. en-copyright= kn-copyright= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name=高柳俊夫 kn-aut-sei=高柳 kn-aut-mei=俊夫 aut-affil-num=1 ORCID= en-aut-name=WadaEiko en-aut-sei=Wada en-aut-mei=Eiko kn-aut-name=和田栄子 kn-aut-sei=和田 kn-aut-mei=栄子 aut-affil-num=2 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部化学科 affil-num=2 en-affil= kn-affil=岡山大学理学部化学科 affil-num=3 en-affil= kn-affil=岡山大学理学部化学科 affil-num=4 en-affil= kn-affil=岡山大学理学部化学科 END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue= article-no= start-page=4 end-page=10 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=199908 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Determination of trace metals in environmental water samples by inductively coupled plasma - mass spectrometry (ICP-MS) kn-title=誘導結合プラズマ―質量分析法による環境水中の微量金属の定量 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Trace metals in water samples, such as tap water, river water, and sea water, were determined by inductively coupled plasma-mass spectrometry (ICP-MS). ICP-MS has sufficient sensitivity to detect even below the concentrations of ppt level, and therefore the samples were not pretreated with a concentration column. Practical samples were diluted by lo-fold with ultrapure water and measured directly by ICP-MS. The measuring time of one sample was 2.5 min, and the data for 30 elements were obtained simultaneously. The concentrations of heavy metals, such as Cr, Mn, Co, Ni, Cu, Zn, As, Cd, Sb, and Pb, in the water samples were in the ranges of 0.05~82ng/ml. Zasu river and Sibukawa (sea water) contained various kinds of metals, and the concentration ranges were spread in a wide range; for example, Mg was 25700 ppb and In was 2 ppt. ICP-MS is found to be a useful and a powerful instrument for trace amounts of elements, and can be applied satisfactorily to the environmental water analysis. en-copyright= kn-copyright= en-aut-name=LeeKyue-Hyung en-aut-sei=Lee en-aut-mei=Kyue-Hyung kn-aut-name=李啓? kn-aut-sei=李 kn-aut-mei=啓? aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name=高柳俊夫 kn-aut-sei=高柳 kn-aut-mei=俊夫 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部化学科 affil-num=2 en-affil= kn-affil=岡山大学理学部化学科 affil-num=3 en-affil= kn-affil=岡山大学理学部化学科 affil-num=4 en-affil= kn-affil=岡山大学理学部化学科 END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue= article-no= start-page=37 end-page=42 dt-received= dt-revised= dt-accepted= dt-pub-year=2003 dt-pub=200308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学周辺の割川水の長期定量データの解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HamasakiKayoko en-aut-sei=Hamasaki en-aut-mei=Kayoko kn-aut-name=M崎佳代子 kn-aut-sei=M崎 kn-aut-mei=佳代子 aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部 affil-num=2 en-affil= kn-affil=岡山大学理学部 END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue= article-no= start-page=15 end-page=18 dt-received= dt-revised= dt-accepted= dt-pub-year=2000 dt-pub=200009 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=HPLCを用いた昆虫のカテコールアミン関連酵素活性測定法 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=AsadaNobuhiko en-aut-sei=Asada en-aut-mei=Nobuhiko kn-aut-name=浅田伸彦 kn-aut-sei=浅田 kn-aut-mei=伸彦 aut-affil-num=1 ORCID= en-aut-name=YamazakiShigeo en-aut-sei=Yamazaki en-aut-mei=Shigeo kn-aut-name=山崎重雄 kn-aut-sei=山崎 kn-aut-mei=重雄 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山理科大学理学部基礎理学科 affil-num=2 en-affil= kn-affil=岡山理科大学理学部基礎理学科 END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue= article-no= start-page=23 end-page=28 dt-received= dt-revised= dt-accepted= dt-pub-year=2001 dt-pub=200109 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=遺伝子レベルで細胞から個体まで研究出来る線虫モデル en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KagawaHiroaki en-aut-sei=Kagawa en-aut-mei=Hiroaki kn-aut-name=香川弘昭 kn-aut-sei=香川 kn-aut-mei=弘昭 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院　自然科学研究科　生命分子科学専攻　（理学部生物学科） END
