Based on the crystal structures, the optimal BVS calculating conditions were determined. As a result, BVS distributions with small deviation were successfully achieved without lowering the reproducibility of other experimental constraints. The geometric asymmetry of PbOn polyhedra was evaluated from the eccentric distance between Pb and gravity center of oxygen atoms. The average eccentric distance was shorter than that in the lead borate crystals, indicating less asymmetry of PbOn units in the RMC glass model. The connectivity between BOn and PbOn units was investigated. It was consequently concluded that the glass had a different network structure from the crystal with the same composition, which might be due to the different chemical bonding character between the lead borate glasses and crystals. en-copyright= kn-copyright= en-aut-name=NagaoMasaaki en-aut-sei=Nagao en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BeninoYasuhiko en-aut-sei=Benino en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MukunokiAtsushi en-aut-sei=Mukunoki en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ChibaTamotsu en-aut-sei=Chiba en-aut-mei=Tamotsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KikuchiTakahiro en-aut-sei=Kikuchi en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakuragiTomofumi en-aut-sei=Sakuragi en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OwadaHitoshi en-aut-sei=Owada en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Environmental Management Center, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=JGC Japan Corporation kn-affil= affil-num=6 en-affil=JGC Japan Corporation kn-affil= affil-num=7 en-affil=JGC Japan Corporation kn-affil= affil-num=8 en-affil=Radioactive Waste Management Funding and Research Center kn-affil= affil-num=9 en-affil=Radioactive Waste Management Funding and Research Center kn-affil= en-keyword=Lead borate glass kn-keyword=Lead borate glass en-keyword=Reverse Monte Carlo modeling kn-keyword=Reverse Monte Carlo modeling en-keyword=Bond valence sum kn-keyword=Bond valence sum en-keyword=Coordination polyhedron kn-keyword=Coordination polyhedron END start-ver=1.4 cd-journal=joma no-vol=130 cd-vols= no-issue=8 article-no= start-page=605 end-page=610 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202281 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Environmental activities on glass in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=In general, glass has been recognized as an environmentally friendly material. However, the production of glass requires a lot of heat energy, and the raw materials also emit CO2 at the melting process. In fact, commercial glasses are not easy to recycle. In glass industry of Japan, various efforts have been made so far to reduce the environmental impact of glass. In this paper, not only glass manufacturing technologies but also glass recycling technologies were reviewed, and the future glass production technologies to achieve carbon neutrality were also introduced. en-copyright= kn-copyright= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BeninoYasuhiko en-aut-sei=Benino en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkaiTomoko en-aut-sei=Akai en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=National Institute of Advanced Industrial Science and Technology (AIST) kn-affil= 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=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=奥付 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=55 end-page=55 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2020年 環境理工学部 博士論文 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=53 end-page=53 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2020年 環境理工学部 研究受賞等 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=45 end-page=51 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2020年 環境物質工学科 学術論文等 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=29 end-page=43 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2020年 環境管理工学科 学術論文等 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=17 end-page=27 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2020年 環境デザイン工学科 学術論文等 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=11 end-page=16 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2020年 環境数理学科 学術論文等 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=7 end-page=10 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Mitigation Effect of Thermal Environment on the Asphalt by Sprayed Water kn-title=散水によるアスファルト上の暑熱環境緩和効果 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this study, water was sprinkled on the asphalt surface during the hottest hours of the day using a sprinkler, and the effect was experimentally verified. An air temperature, a humidity, a ground surface temperature, and a globe temperature which is radiant heat from the ground were measured, and using these measurements, WBGT (Wet-Bulb Globe Temperature), which is an index of thermal stress on the human body, was calculated. In this way, we investigated not only the climate mitigation effect but also the mitigation effect of the thermal environment felt by the human body.
As a result, the following points were clarified in this study: 1) During sprinkling, the air temperature, the black globe temperature, and the WBGT were lower in the sprinkled area than in the controlled area, and the wet-bulb temperature hardly changed. 2) Focusing on the amount of change after watering compared to before watering, the air temperature, the globe temperature, and the WBGT decreased, and the wet-bulb temperature hardly changed. 3) In the sprinkled area, when the WBGT value just before watering is higher than that of the strict caution (WBGT is 28°C or higher), it drops to a level one rank lower, and when the WBGT value just before watering is warning (WBGT value is 25°C or higher), it was almost no change. en-copyright= kn-copyright= en-aut-name=MOROIZUMIToshitsugu en-aut-sei=MOROIZUMI en-aut-mei=Toshitsugu kn-aut-name=諸泉利嗣 kn-aut-sei=諸泉 kn-aut-mei=利嗣 aut-affil-num=1 ORCID= en-aut-name=ITONaoya en-aut-sei=ITO en-aut-mei=Naoya kn-aut-name=伊藤尚也 kn-aut-sei=伊藤 kn-aut-mei=尚也 aut-affil-num=2 ORCID= en-aut-name=MIURATakeshi en-aut-sei=MIURA en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院環境生命科学研究科 affil-num=2 en-affil= kn-affil=前田道路 affil-num=3 en-affil= kn-affil=岡山大学大学院環境生命科学研究科（名誉教授） en-keyword=WBGT kn-keyword=WBGT en-keyword=Air temperature kn-keyword=Air temperature en-keyword=Globe Temperature kn-keyword=Globe Temperature en-keyword=Thermal environment kn-keyword=Thermal environment en-keyword=Sprayed water kn-keyword=Sprayed water END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue=1 article-no= start-page=1 end-page=5 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Estimation of actual evapotranspiration in 3 river basins in Okayama prefecture - Comparison of Morton method and modified Brutsaert & Stricker method - kn-title=岡山県3河川流域における実蒸発散量の推定 : Morton 法と修正 Brutsaert and Stricker 法の比較 en-subtitle= kn-subtitle= en-abstract= kn-abstract= In the study, the actual evaporation was estimated in the Asahi River, the Takahashi River, and the Yoshii River basins in Okayama prefecture for four years from January 1999 to December 2002. The Morton method and the modified Brutsaert and Stricker (B & S) method were applied to the three river basins to estimate the actual evapotranspiration and compare the two methods.
As a result, the actual evapotranspiration by the Morton method was all almost equal to that by the Penman’s potential evapotranspiration, and the evapotranspiration was overestimated rather than the actual evapotranspiration. The actual evapotranspiration by the modified B & S method was below the Penman’s potential evapotranspiration throughout the year, and the total annual amount was about 80% of the potential evapotranspiration. In addition, the modified B & S method showed the general tendency that the actual evapotranspiration was lower in urban area than in the hilly and mountainous areas. en-copyright= kn-copyright= en-aut-name=MOROIZUMIToshitsugu en-aut-sei=MOROIZUMI en-aut-mei=Toshitsugu kn-aut-name=諸泉利嗣 kn-aut-sei=諸泉 kn-aut-mei=利嗣 aut-affil-num=1 ORCID= en-aut-name=MIURATakeshi en-aut-sei=MIURA en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院環境生命科学研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院環境生命科学研究科（名誉教授） en-keyword=Complementary relationship kn-keyword=Complementary relationship en-keyword=Actual evapotranspiration kn-keyword=Actual evapotranspiration en-keyword=Potential evapotranspiration kn-keyword=Potential evapotranspiration 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=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=目次 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=2021 dt-pub=202103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙 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=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=奥付 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=51 end-page=52 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2019年 環境理工学部 博士論文 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=49 end-page=49 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2019年 環境理工学部 研究受賞等 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=39 end-page=48 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2019年 環境物質工学科 学術論文等 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=27 end-page=37 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2019年 環境管理工学科 学術論文等 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=13 end-page=26 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2019年 環境デザイン工学科 学術論文等 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=5 end-page=11 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2019年 環境数理学科 学術論文等 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=1 end-page=4 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202003 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Efficient modelling of 3-d finite element mesh formation with use of 3-d topographic survey kn-title=3次元計測を利用した効率的な3次元有限要素モデル化法の提案 en-subtitle= kn-subtitle= en-abstract= kn-abstract= In this decade, 3-dimensional topographic survey has been developed by using the UAV as like drones. With the technique, the complete topographies of the geo-structures can be measured. Although the accurate shapes of the geo-structures can be obtained, the numerical methods as like the finite element method is are not related to the 3-dimensional survey directly. In this research, the finite mesh modelling technique with use of the 3-D topographic survey is developed. The models of the earth-fill embankments formed from measured 3-D data are introduced as the examples. en-copyright= kn-copyright= en-aut-name=KANESHIGEMinoru en-aut-sei=KANESHIGE en-aut-mei=Minoru

en-subtitle= kn-subtitle= en-abstract= kn-abstract= There are many limitations and difficulties in terms of expanding agricultural lands. Also, some other factors affect the agricultural lands that result in decreases such as climate change, erosion and misuse of the lands. It is clear that these developments in agricultural land use threaten the future of human welfare, social conditions, economic growth and food supply. In this study, we examined the land use and its significance that represent past agriculture and regional characteristics in the Chugoku region including Okayama prefecture and the Seto Inland Sea. Specifically, among the products called as industrial crops, such as cotton, pyrethrum, rush, tobacco, rapeseed, mulberry and tea, were adopted as the indicators. Currently, these landscapes can hardly be seen, only leaves of tobacco and tea can still be seen in mountainous areas. Even in agricultural land usewhich has almost disappeared now, it may have indirect influence as in the case of reclaimed land and rush products. Therefore, we reaffirmed in this study the reasons for their existence and their significance. en-copyright= kn-copyright= en-aut-name=FumikazuIchiminami en-aut-sei=Fumikazu en-aut-mei=Ichiminami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Meltem Okur Din?soy en-aut-sei=Meltem Okur Din?soy en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Enver Erdin Din?soy en-aut-sei=Enver Erdin Din?soy en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Economics and Administrative Sciences, Trakya University kn-affil= affil-num=3 en-affil=School of Applied Sciences, Trakya University kn-affil= en-keyword=industrial crop kn-keyword=industrial crop en-keyword=cultivated area kn-keyword=cultivated area en-keyword=rural geography kn-keyword=rural geography en-keyword=agriculture kn-keyword=agriculture en-keyword=Okayama prefecture kn-keyword=Okayama prefecture END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=23 end-page=48 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=201803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Transitional Analysis on the Production of Cereals, Beans and Potatoes in Okayama Prefecture en-subtitle= kn-subtitle= en-abstract= kn-abstract= The contribution of cereals to economies is undoubtedly very important and has many dimensions in terms of use of cultivated areas, agricultural production, nutrition, domestic and foreign trade and national income. In this study, we examined the characteristics of agricultural production in Okayama prefecture from the viewpoint of grain, beans and potatoes excluding rice, wheat and barley in the long term. These are undoubtedly supposed to have a certain role in complementing the function as the staple food of rice and wheat, etc.Also, according to our literature investigations, researchers have not focused on this context for Okayama Prefecture by not spending enough attention in the past. Therefore, we focus on these subjects in this paper by examining a historical significance. It is observed that some planting area and yield of crops have drastically reduced in Okayama prefecture. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=Enver Erdin Din?soy kn-aut-sei=Enver Erdin Din?soy kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FumikazuIchiminami en-aut-sei=Fumikazu en-aut-mei=Ichiminami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Meltem Okur Din?soy en-aut-sei=Meltem Okur Din?soy en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=School of Applied Sciences, Trakya University kn-affil= affil-num=2 en-affil=Faculty of Environmental Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Economics and Administrative Sciences, Trakya University kn-affil= en-keyword=cultivated area kn-keyword=cultivated area en-keyword=cereals kn-keyword=cereals en-keyword=buckwheat kn-keyword=buckwheat en-keyword=beans kn-keyword=beans en-keyword=potatoes kn-keyword=potatoes en-keyword=Okayama prefecture kn-keyword=Okayama prefecture END start-ver=1.4 cd-journal=joma no-vol=23 cd-vols= no-issue=1 article-no= start-page=1 end-page=21 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=201803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Long Term Change of Agricultural Production in Okayama Prefecture in terms of Rice, Wheat and Barley en-subtitle= kn-subtitle= en-abstract= kn-abstract= The current ratio of dependence on food in Japan has remarkably grown and the significance of food self-sufficiency by concurrent agriculture may decline, while importantly conserving the natural environment, appropriate management of farmland. Okayama prefecture has an agricultural trend over more than 100 years of rice, barley and wheat cropping area with the rise and fall of its agricultural land use from the prior to the Industrial Revolution in Japan. Although rice reduction policy in Japan is scheduled to end in 2017, Japan is strongly subject to rice compared to other grains. In order to understand the role and scope of the agricultural sector in Okayama pref., it is necessary to review the changes in the related agricultural products for the long term. In Okayama pref., the cultivation and processing of some industrial crops including sericulture sector were thriving in the past, but, commercial agriculture was not well developed and the meaning of the production of cereals was greater than current production. Considering the part of agricultural characteristics by examining the cultivation of crops over the long term, planting area survey by variety confirmed that the greatest feature of rice cultivation in Okayama pref. is the diversity of varieties. In addition to various rice varieties, agriculture in Okayama pref. has a high sustainability, resistance and flexibility against changes on climate, policies and land use. en-copyright= kn-copyright= en-aut-name=Meltem Okur Din?soy en-aut-sei=Meltem Okur Din?soy en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Enver Erdin?

Valid response from 24 farmers were obtained and Asparagus had been planted in 30 plots within 74 plots (40.5%). As the result of statistical analysis on the geospatial preference for asparagus fields by logit model in which the geospatial characteristics of plots such as elevation, slope, curvature, acreage and distance from farmhouse were adapted as the explanatory variables while the category of the cultivated crops in there was adapted as the independent variable, it became clear that as for the asparagus plots, small lots were more preferred. On the other hand, the geospatial preference for asparagus plots such as elevation, slope, curvature and distance from farmhouse did not became clear. en-copyright= kn-copyright= en-aut-name=MoritaHidenori en-aut-sei=Morita en-aut-mei=Hidenori kn-aut-name=守田秀則 kn-aut-sei=守田 kn-aut-mei=秀則 aut-affil-num=1 ORCID= en-aut-name=HironakaShoya en-aut-sei=Hironaka en-aut-mei=Shoya kn-aut-name=弘中奨也 kn-aut-sei=弘中 kn-aut-mei=奨也 aut-affil-num=2 ORCID= en-aut-name=MatsumotoYuki en-aut-sei=Matsumoto en-aut-mei=Yuki kn-aut-name=松本雄樹 kn-aut-sei=松本 kn-aut-mei=雄樹 aut-affil-num=3 ORCID= affil-num=1 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=2 en-affil= kn-affil=倉敷市役所 affil-num=3 en-affil= kn-affil=復建調査設計株式会社 en-keyword=Land use kn-keyword=Land use en-keyword=GIS kn-keyword=GIS en-keyword=Thailand kn-keyword=Thailand en-keyword=Asparagus kn-keyword=Asparagus en-keyword=logit model kn-keyword=logit model END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=61 end-page=64 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Evaluation of drop in official air temperature record at Okayama caused by relocation of observation field of Okayama Local Meteorological Observatory - By comparison with records observed at surrounding points - kn-title=岡山地方気象台観測露場移転による気温低下量の推定 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Statistical change in official temperature records at Okayama City caused by relocation of meteorological observation field of Meteorological Agency was evaluated. The observation field of Okayama local meteorological observatory was moved to the Tsushima Campus of Okayama University from the downtown area of Okayama City in March, 2015. Comparison between the air temperature records measured at meteorological agency station and the records at Tanjo Pond in Tsushima Campus, showed 0.56 ℃ drop in annual average before and after relocation. Moreover, comparison between the records of Okayama local meteorological observatory and that at the surrounding meteorological observing 9 stations showed 0.55 ℃ drop in annual average. Those results suggest that the relocation dropped annual average of air temperature by about 0.6 ℃. en-copyright= kn-copyright= en-aut-name=MiuraTakeshi en-aut-sei=Miura en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=1 ORCID= en-aut-name=UedaYu en-aut-sei=Ueda en-aut-mei=Yu kn-aut-name=上田悠生 kn-aut-sei=上田 kn-aut-mei=悠生 aut-affil-num=2 ORCID= en-aut-name=MoritaHidenori en-aut-sei=Morita en-aut-mei=Hidenori kn-aut-name=守田秀則 kn-aut-sei=守田 kn-aut-mei=秀則 aut-affil-num=3 ORCID= en-aut-name=ChikamoriHidetaka en-aut-sei=Chikamori en-aut-mei=Hidetaka kn-aut-name=近森秀高 kn-aut-sei=近森 kn-aut-mei=秀高 aut-affil-num=4 ORCID= en-aut-name=KurokawaMasahiro en-aut-sei=Kurokawa en-aut-mei=Masahiro kn-aut-name=黒川正宏 kn-aut-sei=黒川 kn-aut-mei=正宏 aut-affil-num=5 ORCID= en-aut-name=NakashimaYoshitaka en-aut-sei=Nakashima en-aut-mei=Yoshitaka kn-aut-name=中嶋佳貴 kn-aut-sei=中嶋 kn-aut-mei=佳貴 aut-affil-num=6 ORCID= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=7 ORCID= affil-num=1 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=2 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=3 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=4 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=5 en-affil= kn-affil=岡山大学環境理工学部 affil-num=6 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=7 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 en-keyword=Okayama Local Meteorological Observatory kn-keyword=Okayama Local Meteorological Observatory en-keyword=relocation kn-keyword=relocation en-keyword=drop in air temperature kn-keyword=drop in air temperature END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=55 end-page=59 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Method for predicting minimum air temperature in the next morning using local meteorological observation data - Improvement on minimum air temperature forecasting system utilizing the Internet - kn-title=現地気象観測データを用いた最低気温予測方法とその精度―インターネットを利用した最低気温予報システムの改良― en-subtitle= kn-subtitle= en-abstract= kn-abstract=We have developed a minimum air temperature forecasting system using local meteorological observation data in order to prevent or mitigate the frost damage. In this paper, the correlation between the meteorological factors and the decrease in air temperature during the night was shown. Then minimum air temperature was predicted by the multiple regression equation that uses air temperature and humidity at 18:00 as explanatory variables. As the result, the root mean square error (RMSE) was 2.8°C. When the difference of air temperature between 17:00 and 18:00 was used for the prediction instead of humidity, the RMSE was 3.5°C. Next, the prediction was carried out only in clear nights, then the equation that use air temperature and humidity at 18:00 showed that the RMSE was 1.3°C. Although the predictive accuracy of the equations for clear nights is low on cloudy or rainy nights, we can forecast safely on frosty nights by using those equations in combination with the equations for all nights. en-copyright= kn-copyright= en-aut-name=UedaYu en-aut-sei=Ueda en-aut-mei=Yu kn-aut-name=上田悠生 kn-aut-sei=上田 kn-aut-mei=悠生 aut-affil-num=1 ORCID= en-aut-name=MishimaTakuya en-aut-sei=Mishima en-aut-mei=Takuya kn-aut-name=三島拓也 kn-aut-sei=三島 kn-aut-mei=拓也 aut-affil-num=2 ORCID= en-aut-name=MiuraTakeshi en-aut-sei=Miura en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=3 ORCID= en-aut-name=MoroizumiToshitsugu en-aut-sei=Moroizumi en-aut-mei=Toshitsugu kn-aut-name=諸泉利嗣 kn-aut-sei=諸泉 kn-aut-mei=利嗣 aut-affil-num=4 ORCID= affil-num=1 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=2 en-affil= kn-affil=エイト日本技術開発株式会社 affil-num=3 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=4 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 en-keyword=Minimum air temperature kn-keyword=Minimum air temperature en-keyword=prediction kn-keyword=prediction en-keyword=frost damage kn-keyword=frost damage en-keyword=IT kn-keyword=IT en-keyword=multiple regression analysis kn-keyword=multiple regression analysis END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=29 end-page=54 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Changing Food Production based on Agricultural Enterprises in Tottori Prefecture kn-title=経営部門からみた鳥取県の食料生産の変貌 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The study aims to explain the main features of food production in Tottori prefecture focusing on agricultural enterprises. First, the number of farmers and farm households, the area of cultivated land, and their spatial distribution were analyzed. Then, the production trend on rice, livestock, vegetables such as watermelon and leek, and pears was surveyed. Furthermore, by overlooking the features of each enterprise, food production as a regional agriculture was briefly examined. Farm management in Tottori pref. has long been a small scale selfsufficiency property, but has gradually decayed or specialized. Because agricultural workers are continuously decreasing and aging, farming in Tottori pref. should pay attention to the demand of world food while publicizing a process on food production and farmmanagement carefully. en-copyright= kn-copyright= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name=市南文一 kn-aut-sei=市南 kn-aut-mei=文一 aut-affil-num=1 ORCID= affil-num=1 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 en-keyword=food production kn-keyword=food production en-keyword=enterprise kn-keyword=enterprise en-keyword=vegetables kn-keyword=vegetables en-keyword=pears kn-keyword=pears en-keyword=Tottori prefecture kn-keyword=Tottori prefecture END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=1 end-page=28 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201703 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tourism Inventory of Okayama Prefecture: An Analysis on Main Sightseeing Spots in terms of the Number of Tourists en-subtitle= kn-subtitle= en-abstract= kn-abstract= At the early stage of this paper, Okayama prefecture was analyzed by the author focusing on the tendency of main sightseeing-areas based on the number of tourists for three decades (Ichiminami, 2002). In this study, the main sightseeing spots in Okayama pref. are also examined and the developments are explained in a more detailed and updated perspective by extending over current features and the number of tourists. One of the important reasons in a significant increase in tourists in Okayama is the opening of the highways, the bullet train and cross-linking of the Seto Ohashi Bridge. At the same time, there are some waves in the increase or decrease of the tourist trends appearing from several vital developments such as environmental, climatic, social, economic and spatial. In this regard, research objectives of the study are mainly based on investigating and making a comprehensive study on main sightseeing spots in Okayama pref. to find new tourism values and to provide a tourism inventory of Okayama pref. by means of information, data and clues from the field in/between the tourist destinations such as hotel guests, gardens and castles. Therefore, Okayama pref. has a rich potential of historical and cultural heritage in terms of spatial planning and growth. The important point is that the structural adaptation between historical and cultural assets and the city life should be provided and protected for domestic and foreign tourism as much as creating better futures in health tourism, gastronomy tourism, cultural tourism, belief tourism, congress tourism, thematic tourism and local tourism. en-copyright= kn-copyright= en-aut-name=IchiminamiFumikazu

kn-abstract=Turkey has been undergoing very important economic and social changes since several decades such as economic growth, privatization of state enterprises, liberalization, and integration with the EU, and legislative reforms. All sectors in Turkey and production levels are affected by these changes during the years. Crop production in agriculture is one of the most affected sectors. Many policies by governmental/nongovernmental organizations have been applied and supported for the development of the sector such as modernization, mechanization, irrigation, road constructions, potable water, financial supports, agricultural insurance, and technical supports. Therefore, the main purpose of this paper is to look back and analyze the trend of agricultural changes, land use and related production levels in Turkey. en-copyright= kn-copyright=

However, decline or stagnation trend has continued thereafter. Farm workers are often 50 years old or more, each farmer has cultivated eggplant, rice, two-rowed malting barley in family management by 2 or 3 persons. Work begins in July. Eggplant seedlings are planted in August, harvest begins in October and heating in November. Pest control is necessary throughout the year, but pesticide use has decreased in recent years. In order to suppress the occur -rence of the pests, workers use both the bunker crops like sesame and natural enemies like Amblyseius swirskii . However, because the prices of agricultural materials and fuel are recently soaring, the farm management of eggplant has become increasingly severe. We propose to expand the sales network by advertising and a more aggressive acceptance of new farmers. en-copyright= kn-copyright= en-aut-name=FurutaYuichiro en-aut-sei=Furuta en-aut-mei=Yuichiro kn-aut-name=古田祐一郎 kn-aut-sei=古田 kn-aut-mei=祐一郎 aut-affil-num=1 ORCID= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name=市南文一 kn-aut-sei=市南 kn-aut-mei=文一 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=生活協同組合おかやまコープ affil-num=2 en-affil= kn-affil=岡山大学大学院環境生命科学研究科 en-keyword=eggplant kn-keyword=eggplant en-keyword=greenhouse kn-keyword=greenhouse en-keyword=pest control kn-keyword=pest control en-keyword=farm management kn-keyword=farm management en-keyword=agricultural cooperative kn-keyword=agricultural cooperative en-keyword=Okayama prefecture kn-keyword=Okayama prefecture END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=1 end-page=11 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=201503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Preliminary study on the preserved trees in the central part of Himeji city and Syosya-zan Engyo-ji in terms of civil consciousness en-subtitle= kn-subtitle= en-abstract= kn-abstract=　This study investigated the civil consciousness on the preserved trees in Himeji city, Hyogo prefecture.

As a result, it was revealed that the citizens are not indifferent to the natural environment of trees, etc., they also do not have a strong interest in it in particular. As for preserved tree system, there were some slight differences in the recog -nition between the people who actually take care of trees and administration. People are in favor of the need for the current system of preserved trees. However, in Japan, which is blessed with many things, people do not recognize strongly appreciating the natural environment. en-copyright= kn-copyright= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NoguchiYukiko en-aut-sei=Noguchi en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Din?soyMeltem Okur en-aut-sei=Din?soy en-aut-mei=Meltem Okur kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Din?soyEnver Erdin? en-aut-sei=Din?soy en-aut-mei=Enver Erdin? kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Faculty of Environmental Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=JA Hyogo Informatin Center affil-num=3 en-affil= kn-affil=Faculty of Economics and Administrative Sciences, Trakya University affil-num=4 en-affil= kn-affil=Department of Banking, School of Applied Sciences, Trakya University en-keyword=preserved tree kn-keyword=preserved tree en-keyword=ordinance kn-keyword=ordinance en-keyword=civil consciousness kn-keyword=civil consciousness en-keyword=Himeji city kn-keyword=Himeji city END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=201503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=20 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=201503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=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) ?

An Analysis on the Acreage or Yield of Main Varieties of Rice ? en-subtitle= kn-subtitle= en-abstract= kn-abstract=　In this study, we examined the change of rice cultivation in consideration of the global warming. In Japan, rice which is suitable for subtropical zone is grown even in an environment of cool-temperate climate. Since the rice varieties that resist of cold weather have been developed, rice cultivation spread to north parts of the country gradually. Land productivity of rice has also improved markedly. As a result, northern Japan became the main producer of rice. Now, taking not only crop production but also the landscape formation and preservation of the natural environment into account, we should think about the rural society from different aspects. en-copyright= kn-copyright= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Din?soyMeltem Okur en-aut-sei=Din?soy en-aut-mei=Meltem Okur kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Din?soyEnver Erdin? en-aut-sei=Din?soy en-aut-mei=Enver Erdin? kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Faculty of Environmental Science and Technology, Okayama University affil-num=2 en-affil= kn-affil=Faculty of Economics and Administrative Sciences, Trakya University, Turkey affil-num=3 en-affil= kn-affil=Department of Banking, School of Applied Sciences, Trakya University, Turkey en-keyword=Global warming kn-keyword=Global warming en-keyword=rice cultivation kn-keyword=rice cultivation en-keyword=varieties kn-keyword=varieties en-keyword=acreage kn-keyword=acreage en-keyword=yield kn-keyword=yield en-keyword=Japan kn-keyword=Japan END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page=1 end-page=7 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Numerical Evaluation of the Approximation by an Influence Function kn-title=影響関数による近似の数値評価 en-subtitle= kn-subtitle= en-abstract= kn-abstract=For evaluating statistical models one of the most effective criteria is cross-validation.

In this criterion an influence function is used to estimate the parameters of the models. By the numerical simulation we studied the effect of an influence function.　 Surveying data of the lake depth are used as the sample data. We estimate the shape of lake bottom as spline surface. The estimated parameters and the estimated depths obtained by two criteria are compared and the effect of an information function is analysed. en-copyright= kn-copyright= en-aut-name=BaoHong Mei en-aut-sei=Bao en-aut-mei=Hong Mei kn-aut-name=包紅梅 kn-aut-sei=包 kn-aut-mei=紅梅 aut-affil-num=1 ORCID= en-aut-name=FuedaKaoru en-aut-sei=Fueda en-aut-mei=Kaoru kn-aut-name=笛田薫 kn-aut-sei=笛田 kn-aut-mei=薫 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境学研究科 affil-num=2 en-affil= kn-affil=岡山大学環境生命科学研究科 en-keyword=influence function kn-keyword=influence function en-keyword=information criteria kn-keyword=information criteria en-keyword=CV kn-keyword=CV en-keyword=mGIC kn-keyword=mGIC en-keyword=B-spline kn-keyword=B-spline END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=19 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=201403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=1 cd-vols= no-issue=1 article-no= start-page=108 end-page=113 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=201303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Distribution behavior of inorganic constituents in chemical recycling processes of a municipal waste slag en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OmuraKohei en-aut-sei=Omura en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BeninoYasuhiko en-aut-sei=Benino en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University affil-num=2 en-affil= kn-affil=Environmental Management Center, Okayama University affil-num=3 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University affil-num=4 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University en-keyword=Chemical recycling of wastes kn-keyword=Chemical recycling of wastes en-keyword=Glass kn-keyword=Glass en-keyword=Phase separation kn-keyword=Phase separation en-keyword=Dissolution?reprecipitation kn-keyword=Dissolution?reprecipitation en-keyword=Elemental mapping kn-keyword=Elemental mapping END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=2 article-no= start-page=152 end-page=174 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structural problems of regional development practices in terms of sectoral GDP per capita in Turkey en-subtitle= kn-subtitle= en-abstract= kn-abstract=In integration of Turkey to the EU,the scope of regional programs has been transformed to reach the basic regional socio-economic standards of the Union. In this way, new cooperative regional programs have been applied in Turkey by the EU and Turkey. Therefore, some regional programs in Nomenclature of Territorial Units for Statistics（NUTS）level-2 regions have been examined in this study. In this point, the data of regional GDP per capita by sectors has been used to analyse sectoral disparities in terms of Gini index. To discuss and evaluate the future of the programs on regional disparities, related sector parameters of GDP per capita have been calculated by regression analysis through（balanced）panel data. The ?ndings showed that there is a remarkable sectoral disparity among program regions, and the sector priorities of the programs are not suf?cient to bring any long-term solution for the regional disparities. Finally, Turkey from regional and/or multiregional perspectives needs to reconsider the regional programs for decreasing the disparities as much as development ofthe regions. en-copyright= kn-copyright= en-aut-name=DincsoyEnver Erdinc en-aut-sei=Dincsoy en-aut-mei=Enver Erdinc kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Okayama University, Graduate School of Natural Science and Technology affil-num=2 en-affil= kn-affil=Okayama University, Graduate School of Environmental Science and Technology en-keyword=Regional program kn-keyword=Regional program en-keyword=Sectoral GDP per capita kn-keyword=Sectoral GDP per capita en-keyword=Gini index kn-keyword=Gini index en-keyword=the EU kn-keyword=the EU en-keyword=Turkey kn-keyword=Turkey END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=80 end-page=89 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Research on Quality Assurance in Teacher Training course in Okayama University (1)?

en-abstract= kn-abstract=In Japan, the number of full-time farm households had continued to decrease since the latter half of 20th century. The number of part-time households has been also decreasing remarkably in the last twenty years. Cultivated acreage also aligned with these tendencies and it has decreased. As a result, the farmland which is not cultivated increased and it may also grow into a social problem. Therefore, the present condition and future view of Japanese agriculture was elaborately examined in the study by analyzing the transition of non-cultivated arable lands from a historical perspective. en-copyright= kn-copyright= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DincsoyEnver Erdinc en-aut-sei=Dincsoy en-aut-mei=Enver Erdinc kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Faculty of environmental science and technology, Okayama University affil-num=2 en-affil= kn-affil=Department of Banking, School of Applied Sciences, Trakya University en-keyword=Non-cultivated arable land kn-keyword=Non-cultivated arable land en-keyword=part-time farm households kn-keyword=part-time farm households en-keyword=non-farm households kn-keyword=non-farm households en-keyword=Japan kn-keyword=Japan 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=2013 dt-pub=201303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=2013 dt-pub=201303 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=2012 dt-pub=201203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=奥付 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=2012 dt-pub=201203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2011年度環境物質工学科研究報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=2012 dt-pub=201203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2011年度環境管理工学科研究報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=2012 dt-pub=201203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2011年度環境デザイン工学科研究報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=2012 dt-pub=201203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2011年度環境数理学科研究報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=23 end-page=43 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Landscape and Sightseeing of Bittchu-Kokubunji Based on the Viewpoints of Tourists and Local Residents kn-title=観光客と地域住民からみた岡山県総社市 備中国分寺の景観と観光 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, we examined the landscape and sightseeing at Bittchu-Kokubunji in Okayama prefecture carrying out the questionnaire survey to tourists and local residents. Both tourists and local residents estimate that the landscape ofBittchu-Kokubunji is wonderful, and it has several images such as historical, quiet, and old-fashioned, etc. AlthoughBittchu-Kokubunji is one of the famous tourist resorts in Okayama prefecture, there are quite few tourists compared with the degree of notability. Almost all tourists' age was 50 or more. As more active sightseeing activities, the number of times of holding events, such as an announcement of traditional performing arts, lighting of a five-storied pagoda, photograph or a sketching convention, needs to be increased. An attractive tourist resort should be created by the cooperation of local residents and administration. en-copyright= kn-copyright= en-aut-name=MizutaTomoya en-aut-sei=Mizuta en-aut-mei=Tomoya kn-aut-name=水田智也 kn-aut-sei=水田 kn-aut-mei=智也 aut-affil-num=1 ORCID= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name=市南文一 kn-aut-sei=市南 kn-aut-mei=文一 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=(株)三浦工業 affil-num=2 en-affil= kn-affil=岡山大学環境理工学部環境管理工学科景観管理学分野 en-keyword=Landscape kn-keyword=Landscape en-keyword=Sightseeing kn-keyword=Sightseeing en-keyword=Local residents kn-keyword=Local residents en-keyword=Bittchu-Kokubunji kn-keyword=Bittchu-Kokubunji END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=7 end-page=21 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Survey Study of University Students’ Awareness on Social Contribution and Regional Cooperation kn-title=大学生の社会貢献・地域連携に対する意識 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recently, competition among universities has a whole new face, and emphasis is given toward interdependence and interactive evolution between universities and regions. From this social perspective, universities should contribute to regional development by serving the regional society using results of intellectual work, and it is necessary for universities to accomplish social contribution and regional cooperation strategically. One of the most important parts in strategic planning is that students participate in activities for social contribution and regional cooperation. This paper presents a survey of the university students’ awareness on social contribution and regional cooperation using several statistical methods and attempts to find factors which affect activities for social contribution and regional cooperation using logistic regression analysis. en-copyright= kn-copyright= en-aut-name=NaMyungjin en-aut-sei=Na en-aut-mei=Myungjin kn-aut-name=羅明振 kn-aut-sei=羅 kn-aut-mei=明振 aut-affil-num=1 ORCID= en-aut-name=ArakiMasaru en-aut-sei=Araki en-aut-mei=Masaru kn-aut-name=荒木勝 kn-aut-sei=荒木 kn-aut-mei=勝 aut-affil-num=2 ORCID= en-aut-name=KuriharaKoji en-aut-sei=Kurihara en-aut-mei=Koji kn-aut-name=栗原考次 kn-aut-sei=栗原 kn-aut-mei=考次 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院社会文化科学研究科 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学大学院環境学研究科 en-keyword=University students’ awareness kn-keyword=University students’ awareness en-keyword=social contribution and regional cooperation kn-keyword=social contribution and regional cooperation en-keyword=volunteer activities kn-keyword=volunteer activities en-keyword=exploratory factor analysis kn-keyword=exploratory factor analysis en-keyword=logistic regression analysis kn-keyword=logistic regression analysis END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=201203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Basic Reproductive Ratio for Epdiemic Models (Review) kn-title=感染症数理モデルの再生産数(レビュー) en-subtitle= kn-subtitle= en-abstract= kn-abstract=We review some fundamental results on the basic reproductive ratio of models in epidemiology following several documents.

The wet ball milling of the simulated waste slag powder was performed using a ball mill pot and balls in air for 10 - 100 h at room temperature with the rotational speed fixed at 200 rpm. The fractions of CaO and Fe2O3 in the specimens obtained by wet-ball-milling the simulated waste slag powder decreased, that of SiO2 increased, and those of Al2O3 and Na2O hardly changed. These specimens contained 0.1 ? 0.8mass% ZrO2. Appropriate solution and time for wet ball milling were 300 ml distilled water and 20 h, respectively. When the wet ball milling of the simulated waste slag powder was performed twice, the fractions of CaO, Al2O3 and Fe2O3 in the specimen obtained after repeated wet ball milling decreased, those of SiO2 and ZrO2 increased and that of Na2O hardly changed in comparison with those in the specimen wet-ball-milled once. The insoluble end product obtained by soaking the specimen wet-ball-milled once in 6M HCl for 20 hours was composed of 98.5mass% SiO2 and 0.6mass% or less other oxides and is usable as glass material. en-copyright= kn-copyright= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name=崎田真一 kn-aut-sei=崎田 kn-aut-mei=真一 aut-affil-num=1 ORCID= en-aut-name=BeninoYasuhiko en-aut-sei=Benino en-aut-mei=Yasuhiko kn-aut-name=紅野安彦 kn-aut-sei=紅野 kn-aut-mei=安彦 aut-affil-num=2 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name=難波徳郎 kn-aut-sei=難波 kn-aut-mei=徳郎 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境管理センター affil-num=2 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 affil-num=3 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 en-keyword=Inorganic slag kn-keyword=Inorganic slag en-keyword=EDTA kn-keyword=EDTA en-keyword=Wet ball milling kn-keyword=Wet ball milling en-keyword=Recycling kn-keyword=Recycling END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue= article-no= start-page=126 end-page=135 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120319 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Research on the Effect of a Teacher Training Program for Freshmen,“The Visit to Their Old High School” kn-title=「母校訪問」を核とする全学教職課程初年次プログラムの成果と課題 en-subtitle= kn-subtitle= en-abstract= kn-abstract=岡山大学は全学の教職課程を担う「教師教育開発センター」を平成22年度に創設し、学部の枠を超えた教員養成教育の質保証に取り組んでいる。教育実習事前事後指導や教育実習ならびに教職実践演習（平成25年度から実施）等を中心とする「全学教職コア・カリキュラム」の企画・運営だけではなく、これらの科目の教育成果とその課題を検証し、FD的視点に基づくカリキュラム開発と改善とを進めている。「母校訪問」とは、教育学部以外の学生（文学部、法学部、経済学部、理学部、工学部、環境理工学部、農学部、マッチングプログラムコース）のうち、改正後の教育職員免許法が適用される平成22 年度以降入学生（現１、２年生）を対象に、センターが独自に開発した１年次生対象のプログラムである。本稿ではその成果と課題の検証を通して、いわゆる「開放制」と「大学における教員養成」の原則に基づいた教員養成教育の可能性を検討する。 en-copyright= kn-copyright= en-aut-name=GotoDaisuke en-aut-sei=Goto en-aut-mei=Daisuke kn-aut-name=後藤大輔 kn-aut-sei=後藤 kn-aut-mei=大輔 aut-affil-num=1 ORCID= en-aut-name=TakahataHiroshi en-aut-sei=Takahata en-aut-mei=Hiroshi kn-aut-name=旗浩志 kn-aut-sei=旗 kn-aut-mei=浩志 aut-affil-num=2 ORCID= en-aut-name=KashidaTakeshi en-aut-sei=Kashida en-aut-mei=Takeshi kn-aut-name=樫田健志 kn-aut-sei=樫田 kn-aut-mei=健志 aut-affil-num=3 ORCID= en-aut-name=MishimaTomotaka en-aut-sei=Mishima en-aut-mei=Tomotaka kn-aut-name=三島知剛 kn-aut-sei=三島 kn-aut-mei=知剛 aut-affil-num=4 ORCID= en-aut-name=EgiEiji en-aut-sei=Egi en-aut-mei=Eiji kn-aut-name=江木英二 kn-aut-sei=江木 kn-aut-mei=英二 aut-affil-num=5 ORCID= en-aut-name=SodaKayoko en-aut-sei=Soda en-aut-mei=Kayoko kn-aut-name=曽田佳代子 kn-aut-sei=曽田 kn-aut-mei=佳代子 aut-affil-num=6 ORCID= en-aut-name=TakahashiKayo en-aut-sei=Takahashi en-aut-mei=Kayo kn-aut-name=高橋香代 kn-aut-sei=高橋 kn-aut-mei=香代 aut-affil-num=7 ORCID= en-aut-name=KagaMasaru en-aut-sei=Kaga en-aut-mei=Masaru kn-aut-name=加賀勝 kn-aut-sei=加賀 kn-aut-mei=勝 aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=岡山大学教師教育開発センター affil-num=2 en-affil= kn-affil=岡山大学教師教育開発センター affil-num=3 en-affil= kn-affil=岡山大学教師教育開発センター affil-num=4 en-affil= kn-affil=岡山大学教師教育開発センター affil-num=5 en-affil= kn-affil=岡山大学教師教育開発センター affil-num=6 en-affil= kn-affil=岡山大学教師教育開発センター affil-num=7 en-affil= kn-affil=岡山大学大学院教育学研究科 affil-num=8 en-affil= kn-affil=岡山大学大学院教育学研究科 en-keyword=母校訪問 kn-keyword=母校訪問 en-keyword=全学教職課程初年次プログラム kn-keyword=全学教職課程初年次プログラム en-keyword=開放制教員養成教育の質保証 kn-keyword=開放制教員養成教育の質保証 en-keyword=FD kn-keyword=FD END start-ver=1.4 cd-journal=joma no-vol=117 cd-vols= no-issue=1371 article-no= start-page=1195 end-page=1198 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=200911 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Chemical recycling of municipal waste slag by using phase separation en-subtitle= kn-subtitle= en-abstract= kn-abstract=A chemical recycling method by using phase separation was applied to municipal waste slags. Glasses were prepared from incineration ash and ash-melted slag, where B(2)O(3) was added to promote phase separation. The glasses were heat-treated at temperatures higher than their glass transition temperatures, and they were soaked in hydrochloric acid, leaching CaO, Fe(2)O(3), K(2)O, and S. Transparent and colorless solids containing ca. 80 mass% of SiO(2) were successfully obtained as residues. It was suggested that phase separation took place not in the heat-treatment but in the vitrification process, and further characterizations are however required to investigate the phenomena at microscopic levels in the recycling processes. en-copyright= kn-copyright= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurodaYutaro en-aut-sei=Kuroda en-aut-mei=Yutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=BeninoYasuhiko en-aut-sei=Benino en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University affil-num=2 en-affil= kn-affil=Faculty of Environmental Science and Technology, Okayama University affil-num=3 en-affil= kn-affil=Environmental Management Center, Okayama University affil-num=4 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University en-keyword=Municipal waste slag kn-keyword=Municipal waste slag en-keyword=Waste recycling kn-keyword=Waste recycling en-keyword=Chemical recycling kn-keyword=Chemical recycling en-keyword=Glass kn-keyword=Glass END start-ver=1.4 cd-journal=joma no-vol=118 cd-vols= no-issue=1379 article-no= start-page=603 end-page=607 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=201007 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Phase separation of borosilicate glass containing sulfur en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 10Na(2)S?30B(2)O(3)?60SiO(2) (mol %) glass was prepared, and the changes in glass structure and chemical state of sulfur caused by phase separation were investigated. In the as-prepared and heat-treated glasses, sulfur was present as S(2)? anion and polysulfide S(2)? and S(3)? anions, and Si?S and B?S bonds were not confirmed. A phase separation by spinodal decomposition was observed after heat-treatment, where sulfur was preferentially distributed to borate-rich phase. Even after the phase separation, formation of non-bridging oxygen was not recognized. The preferential distribution of sulfur anions in the present glass was explainable on the basis of the change in population of sodium ions, which compensated the negatively-charged sulfur anions. en-copyright= kn-copyright= en-aut-name=SaikiKeiji en-aut-sei=Saiki en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=BeninoYasuhiko en-aut-sei=Benino en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University affil-num=2 en-affil= kn-affil=Environmental Management Center, Okayama University affil-num=3 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University affil-num=4 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University en-keyword=Phase separation kn-keyword=Phase separation en-keyword=Borosilicate glass kn-keyword=Borosilicate glass en-keyword=Chemical state of sulfur kn-keyword=Chemical state of sulfur en-keyword=Glass structure kn-keyword=Glass structure 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=2011 dt-pub=20110318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=奥付 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=2011 dt-pub=20110318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2010年度環境物質工学科研究報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=2011 dt-pub=20110318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2010年度環境管理工学科研究報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=2011 dt-pub=20110318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2010年度環境デザイン工学科研究報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=2011 dt-pub=20110318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=2010年度環境数理学科研究報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=35 end-page=39 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20110318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Improvement of complementary relationship-based evapotranspiration model kn-title=補完関係式を用いた実蒸発散量推定式の改良 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Advection-Aridity(AA) model can calculate actual evapotranspiration by using only meteorological data. However, comparing the model with Penman equation showed that AA model doesn’t properly evaluate evapotranspiration from urban moisture area. In urban area, Actual evaporation from water calculated by AA model(E) are much less than that by Penman equation(Epo). Multiple regression analysis using estimation results indicates that the difference between the models is due to the difference of the sensitivity to vapor pressure deficit between the models. To improve this problem, modification coefficient k, defined as k=a･albedo+b, is suggested. Regression coefficients a, b are determined as satisfying k=Epo/E for water and k=1 for urban surface. By using this coefficient k, evaporation from water is nearly equal to value estimated by Penman equation, while evaporation from urban surface is changeless. en-copyright= kn-copyright= en-aut-name=NakamichiTakeshi en-aut-sei=Nakamichi en-aut-mei=Takeshi kn-aut-name=中道丈史 kn-aut-sei=中道 kn-aut-mei=丈史 aut-affil-num=1 ORCID= en-aut-name=MoroizumiToshitsugu en-aut-sei=Moroizumi en-aut-mei=Toshitsugu kn-aut-name=諸泉利嗣 kn-aut-sei=諸泉 kn-aut-mei=利嗣 aut-affil-num=2 ORCID= en-aut-name=MiuraTakeshi en-aut-sei=Miura en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院環境学研究科 affil-num=2 en-affil= kn-affil=岡山大学環境理工学部 affil-num=3 en-affil= kn-affil=岡山大学環境理工学部 en-keyword=Complementary relationship kn-keyword=Complementary relationship en-keyword=Actual evapotranspiration kn-keyword=Actual evapotranspiration en-keyword=Potential evapotranspiration kn-keyword=Potential evapotranspiration en-keyword=Water budget kn-keyword=Water budget END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=7 end-page=33 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20110318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Changes and Problems of Commercial Activities in terms of the Questionnaire Survey in Omote-cho as the Central Shopping Street in Okayama City kn-title=岡山市の商業活動の推移と課題―中心商店街、表町地区の分析を中心にして― en-subtitle= kn-subtitle= en-abstract= kn-abstract=The present study mainly studied some properties of retail stores on the central shopping streets in Okayama City while looking back on the transition of the commerce. Second, we investigated the actual conditions of most retail stores in Omote-cho in terms of the questionnaire survey. Third, we considered the problems and measures on retail stores, a little. The charm of the central shopping streets has decreased relatively in Okayama City due to the advancement of a large-scale stores and the location competition of convenience stores. The number of empty stores has increased and the amount of the pedestrian traffic, the value of sales, and the number of retail stores have shown the decreasing tendency in eight commercial blocs in Omote-cho. Therefore, the unique features in Omote-cho should be polished while esteeming the history and the culture. The charm and/or the atmosphere of traditional commercial blocs is requested to be created while sending new informations that continue to create young person's fashion and culture. en-copyright= kn-copyright= en-aut-name=HanJing en-aut-sei=Han en-aut-mei=Jing kn-aut-name=?静 kn-aut-sei=? kn-aut-mei=静 aut-affil-num=1 ORCID= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name=市南文一 kn-aut-sei=市南 kn-aut-mei=文一 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=元岡山大学大学院環境学研究科博士前期課程 affil-num=2 en-affil= kn-affil=岡山大学環境理工学部 en-keyword=Retail Stores kn-keyword=Retail Stores en-keyword=Central Shopping Street kn-keyword=Central Shopping Street en-keyword=Questionnaire Survey kn-keyword=Questionnaire Survey en-keyword=Omote-cho kn-keyword=Omote-cho en-keyword=Okayama City kn-keyword=Okayama City END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=1 article-no= start-page=1 end-page=5 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20110318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Validation of Dollar cost averaging investment method kn-title=ドルコスト平均法を用いた投資の有効性の検証 en-subtitle= kn-subtitle= en-abstract= kn-abstract=As a method of long term investment for private investor, the dollar cost averaging investment method is well known and seems to reduce the purchase cost because we purchase risk assets with same amount of monye every month, then we purchase many assets when the price of assets is low and few assets when the price is high. On the other hand, if the expectation of the return of the risk assets is positive, we have the maximum expectation of return when we purchase the risk assets with all of money to invest. To reduce the risk of investment, diversified investments are effective. However question whehter we use the dollar cost averaging investment method or investe money all at once to well-diversified risk assets remains. In this study, we validate the effecte of the ddollar cost averaging investment method by Monte Carlo simulation. en-copyright= kn-copyright= en-aut-name=ToujiMasayuki en-aut-sei=Touji en-aut-mei=Masayuki kn-aut-name=田路正幸 kn-aut-sei=田路 kn-aut-mei=正幸 aut-affil-num=1 ORCID= en-aut-name=FuedaKaoru en-aut-sei=Fueda en-aut-mei=Kaoru kn-aut-name=笛田薫 kn-aut-sei=笛田 kn-aut-mei=薫 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院環境学研究科 affil-num=2 en-affil= kn-affil=岡山大学環境理工学部 en-keyword=Dollar cost averaging kn-keyword=Dollar cost averaging en-keyword=investment kn-keyword=investment en-keyword=Monte Carlo simulation kn-keyword=Monte Carlo simulation en-keyword=Stock price index kn-keyword=Stock price index 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=2011 dt-pub=20110318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=目次 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=2011 dt-pub=20110318 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=表紙 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岡山大学環境理工学部 kn-aut-sei=岡山大学環境理工学部 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=31 cd-vols= no-issue= article-no= start-page=26 end-page=31 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=200912 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Material recycling of inorganic sludge by wet ball milling kn-title=湿式ボールミル法を用いた無機性汚泥の再資源化技術の開発 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The possibility of material recycling of inorgamic sludge by wet ball milling with distrilled water and an ethylenediaminetetraacetic acid disodium salt dehydrate (EDTA・2Na・2H(2)O)reagent was investigated. The inorganic sludge consisted of 14.1mass% of the heat-treated sludge obtained after drying and heat treatment, 20.1mass% of active carbon, and 65.9mass% of water. The wet ball milling of the heat-treated sludge was performed using a ball pot and balls in air for 40 h at room temperature with the rotational speed fixed at 200rpm. The fractions of Mn, Fe, Ni, Cu, and Zr in the specimens obtained by wet-ball-milling the heat-treated sludge decreased and those of Si and Al increased. Appropriate content of distilled water and weight of the heat-treated sludge for wet ball milling were 150-250 ml and 4.5 g or less, respectively. When the wet ball milling of the heat-treated sludge was perfomed twice,the fractions of Mn, Fe, Ni, Cu, and Zr in the specimen obtained after repeated wet ball milling remarkably decreased and that of Si increased in comparison with those in the specimens wet-ball-milled once. This suggests that the repeat of wet ball milling of the heat-treated sludge leads to a colorless specimen without colored ions such as Mn, Fe, Ni, and Cu. en-copyright= kn-copyright= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name=崎田真一 kn-aut-sei=崎田 kn-aut-mei=真一 aut-affil-num=1 ORCID= en-aut-name=KurodaRyusuke en-aut-sei=Kuroda en-aut-mei=Ryusuke kn-aut-name=黒田龍介 kn-aut-sei=黒田 kn-aut-mei=龍介 aut-affil-num=2 ORCID= en-aut-name=BeninoYasuhiko en-aut-sei=Benino en-aut-mei=Yasuhiko kn-aut-name=紅野安彦 kn-aut-sei=紅野 kn-aut-mei=安彦 aut-affil-num=3 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name=難波徳郎 kn-aut-sei=難波 kn-aut-mei=徳郎 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境管理センター affil-num=2 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 affil-num=3 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 affil-num=4 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 en-keyword=Inorganic sludge kn-keyword=Inorganic sludge en-keyword=EDTA kn-keyword=EDTA en-keyword=Wet ball milling kn-keyword=Wet ball milling en-keyword=Recycling kn-keyword=Recycling END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2005 dt-pub=20050320 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=津島岡大遺跡 16　―第17・22次調査―　（環境理工学部棟新営） en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=岩ｱ志保 kn-aut-sei=岩ｱ kn-aut-mei=志保 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=野崎貴博 kn-aut-sei=野崎 kn-aut-mei=貴博 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=高田貫太 kn-aut-sei=高田 kn-aut-mei=貫太 aut-affil-num=3 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=高田浩司 kn-aut-sei=高田 kn-aut-mei=浩司 aut-affil-num=4 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=山本悦世 kn-aut-sei=山本 kn-aut-mei=悦世 aut-affil-num=5 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=能城修一 kn-aut-sei=能城 kn-aut-mei=修一 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil= kn-affil= affil-num=6 en-affil= kn-affil= END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue= article-no= start-page=2 end-page= 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= kn-title=環境管理センター設立20周年によせて en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KonoIichiro en-aut-sei=Kono en-aut-mei=Iichiro kn-aut-name=河野伊一郎 kn-aut-sei=河野 kn-aut-mei=伊一郎 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境理工学部 END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue= article-no= start-page=2 end-page=3 dt-received= dt-revised= dt-accepted= dt-pub-year=1997 dt-pub=199707 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=都市の時代と地球環境問題 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KawaraOsami en-aut-sei=Kawara en-aut-mei=Osami kn-aut-name=河原長美 kn-aut-sei=河原 kn-aut-mei=長美 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境理工学部 END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue= article-no= start-page=3 end-page=10 dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=199808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大字における廃棄物管理について en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KohnoIichiro en-aut-sei=Kohno en-aut-mei=Iichiro kn-aut-name=河野伊一郎 kn-aut-sei=河野 kn-aut-mei=伊一郎 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境理工学部 END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue= article-no= start-page=26 end-page=31 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=Evaluation of genotoxic potential in sewage and treated effluent with the umu-test kn-title=Umu試験による生活系排水の遺伝毒性評価 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The umu-test, which can detect genotoxic activites of a wide variety of environmental carcinogens and mutagenes, was carried out with samples from several sewage treatment processes. We applied the umu-test to raw sewage and treated effluent from two points of view, one is to evaluate a treatment process and the other is to identify the genotoxic substances. The original strain of umu-test, Salmonella typhimurium TA1535/pSK1002 can detect nonspecific genotoxicity, on the other hand, by using S. typhimurium NM2009 of the umu-test highly sensitive to aromatic amines, genotoxicity related to aromatic amines is measured. The result showed that genotoxic substances which have the polycyclic aromatic amino structures in the sewage remained after biological treatment. Tow-step HPLC fractionation followed by MS analysis to identify the genotoxic substances was applied to samples to detect mutagenic and carcinogenic heterocyclic amines. The concentration of Trp-P-1 and Trp-P-2 determined in the effluent caluculated from HPLC-UV analysis were on the order of 10(-5) mg/L. Because of the possibility of the reuse of wastewater in urban areas, the need for the investigation of the safety of the treated water from the sewage treatment plants was suggested, in order to evaluate strategies for advanced treatment, if necessary. en-copyright= kn-copyright= en-aut-name=MohriShino en-aut-sei=Mohri en-aut-mei=Shino kn-aut-name=毛利紫乃 kn-aut-sei=毛利 kn-aut-mei=紫乃

The purpose of this study is to develop a measuring system for subsurface contamination in which a so-called FDR (Frequency Domain Refiectometry) and FDR-V (with Vector network analyzer) system was employed to measure the salinity and oil contaminant. This FDR and FDR-V method is a coaxial probe method, which allows the measurement of the dielectric. The experimental study indicates the possibility in measuring both the contaminant concentration and volumetric moisture content. In addition, the method for obtaining the effective porosity using this equipment was shown. Concretely, the sensor was inserted in the ground, and the liquid in which the dielectric constant differed on the water in the circumference was injected, and the method for obtaining the effective porosity from the change of the dielectric constant was proposed. en-copyright= kn-copyright= 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=1 ORCID= en-aut-name=KomatsuMitsuru en-aut-sei=Komatsu en-aut-mei=Mitsuru kn-aut-name=小松満 kn-aut-sei=小松 kn-aut-mei=満 aut-affil-num=2 ORCID= en-aut-name=KimMan-il en-aut-sei=Kim en-aut-mei=Man-il kn-aut-name=金萬鎰 kn-aut-sei=金 kn-aut-mei=萬鎰 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境理工学部 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=Dielectric constant kn-keyword=Dielectric constant en-keyword=Contamination kn-keyword=Contamination en-keyword=Frequency Domain Refiectometry kn-keyword=Frequency Domain Refiectometry en-keyword=In-situ kn-keyword=In-situ en-keyword=Effective porosity kn-keyword=Effective porosity END start-ver=1.4 cd-journal=joma no-vol=26 cd-vols= no-issue= article-no= start-page=17 end-page=22 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=200411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Analysis of biodegradability for polyethylene glycol via numerical simulation kn-title=数値シミュレーションによるポリエチレングリコール生分解性解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We examined the biodegradability of polyethylene glycol by analyzing gel permeation chromatography patterns, which were obtained before and after cultivation of a microbial consortium E-1 in culture media containing polyethylene glycol as its sole carbon source. We solved an inverse problem of the initial value problem, which consists of an exogenous depolymerization model and the initial weight distribution, in order to determine an oxidation rate, for which the solution of the initial value problem also satisfies the final condition. Given the oxidation rate, we simulated the transition of the weight distribution solving the initial value problem. We interpret the result that reflects a physical significance of the molecular weight on the oxidation rate, and reach a conclusion concerning the role of the membrane transport in exogenous depolymerization processes. en-copyright= kn-copyright= en-aut-name=WatanabeMasaji en-aut-sei=Watanabe en-aut-mei=Masaji kn-aut-name=渡辺雅二 kn-aut-sei=渡辺 kn-aut-mei=雅二 aut-affil-num=1 ORCID= en-aut-name=KawaiFusako en-aut-sei=Kawai en-aut-mei=Fusako kn-aut-name=河合富佐子 kn-aut-sei=河合 kn-aut-mei=富佐子 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学環境理工学部 affil-num=2 en-affil= kn-affil=岡山大学資源生物科学研究所 en-keyword=biodegradation kn-keyword=biodegradation en-keyword=polyethylene glycol kn-keyword=polyethylene glycol en-keyword=exogenous depolymerization kn-keyword=exogenous depolymerization en-keyword=mathematical model kn-keyword=mathematical model en-keyword=numerical simulation kn-keyword=numerical simulation END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue= article-no= start-page=11 end-page=15 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=200710 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Material recycling of blast furnace slag by phase separation of glass kn-title=ガラスの分相現象を利用した高炉水砕スラグの再資源化技術の開発 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A novel recycling process of blast furnace slag was developed in order to obtain colorless silica−rich solids by using phase separation of borosilicate glass. B(2)O(3) was added to blast furnace slag to promote the phase separation. The slag glasses were heat-treated above glass transition temperatures. The slag glass prepared from blast furnace slag gelled after the heat treatment and the subsequent three types of acid treatment. The ratios of SiO(2) component in the gels were 40 - 60mass%. On the other hand, phase separation was observed on the surface of the slag glasses prepared from pre-treated slag by 2.5N HCI after the heat treatment. After soaking in acid, they did not gel and changed to insoluble colorless solids. According to compositional analyses, it was found that the insoluble colorless solids contained 70 - 90mass% SiO(2). No colored ions such as Cr, Mn, and Fe were confirmed in the remaining insolubles by optical absorption measurement. Therefore, the colorless silica-rich solids were successfully obtained in the present process. The end products obtained in the present process are expected as material of glass. en-copyright= kn-copyright= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name=崎田真一 kn-aut-sei=崎田 kn-aut-mei=真一 aut-affil-num=1 ORCID= en-aut-name=MikamiSyuuhei en-aut-sei=Mikami en-aut-mei=Syuuhei kn-aut-name=三上修平 kn-aut-sei=三上 kn-aut-mei=修平 aut-affil-num=2 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name=難波徳郎 kn-aut-sei=難波 kn-aut-mei=徳郎 aut-affil-num=3 ORCID= en-aut-name=MiuraToshinari en-aut-sei=Miura en-aut-mei=Toshinari kn-aut-name=三浦嘉也 kn-aut-sei=三浦 kn-aut-mei=嘉也 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学保健環境センター環境安全部門 affil-num=2 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 affil-num=3 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 affil-num=4 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 en-keyword=Blast furnace slag kn-keyword=Blast furnace slag en-keyword=Recycling kn-keyword=Recycling en-keyword=Colorless silica-rich solids kn-keyword=Colorless silica-rich solids en-keyword=Phase separation kn-keyword=Phase separation en-keyword=Glass kn-keyword=Glass END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=175 end-page=181 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=19990226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Commencer...et la suite : deux obsessions majeures de l'ecriture en-subtitle= kn-subtitle= en-abstract= kn-abstract=What is the meanig of the first sentence, and then the meaning of the full stop?

The point at issue in dispute was whether the industry of the pre-Meiji era had so far advanced as to the "Manufacture Stage" that precedes the "Modern Factory Stage" set in the theories of Marx and Lenin. In the ride of regression of Marxism the dispute seems to be now brought to a close. However, as the issue is closely related to the modernization in general, the discussion is sure to go on further in the future. The paper first surveys industry regions of pre-Meiji Japan, second introduces briefly important opinions of the dispute, then precisely examines the stage theories of Marx and Lenin, trying to find a correct answer that accords with the two. That it poses a question to the negative evaluation of the putting-out system and tries to find its proper place in the development of the production forms of modern capitalism and would thus get a better solution of the problem. The paper finally mentions the current active discussions about proto-industry and about the analysis of the international trade among Asian countries at the end of the 19t century and shows their relations to the dispute above. kn-abstract= en-copyright= kn-copyright= en-aut-name=TonomuraNaohiko en-aut-sei=Tonomura en-aut-mei=Naohiko kn-aut-name=外村直彦 kn-aut-sei=外村 kn-aut-mei=直彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=147 end-page=158 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=19990226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photoconductive and Photovoltaic Properties in Cadmium Bismuth Aluminate Glasses en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photo-induced phenomena such as photoconductive and photovoltaic effects were investigated for the glasses in CdO-Bi(2)O(3)-Al(2)O(3) system. Photoconductive effect was characterized by a slow decay of photocurrent (persitent photoconductivity). The decay rate decreased with increasing CdO content and decreasing Bi(2)O(3) content. Photovoltage was very small at room temperature but increased to an obvious value on heating. The photoconductivity and photovoltage were increased with CdO content and enhanced by heat treatment in air. The valence band spectra of X-ray photoelectron spectroscopy showed that the hybridization of Cd 4d and O 2p orbitals increases with decreasing Bi(2)O(3) content and increasing CdO content in the glasses. As the results maximum tends to flat. This type of band structure inhibits the rapid recombination of electrons and holes. The persistent photoconductivity of the glasses may be attributed to deep energy level of DX centers. Deep energy levels of the glasses are able to prevent the recombination because they have a repulsive barrier for both electron emission and capture. en-copyright= kn-copyright= en-aut-name=ChenDanping en-aut-sei=Chen en-aut-mei=Danping kn-aut-name=陳丹平 kn-aut-sei=陳 kn-aut-mei=丹平 aut-affil-num=1 ORCID= en-aut-name=WatanabeTomohiro en-aut-sei=Watanabe en-aut-mei=Tomohiro kn-aut-name=渡辺智大 kn-aut-sei=渡辺 kn-aut-mei=智大 aut-affil-num=2 ORCID= en-aut-name=MiuraYoshinari en-aut-sei=Miura en-aut-mei=Yoshinari kn-aut-name=三浦嘉也 kn-aut-sei=三浦 kn-aut-mei=嘉也 aut-affil-num=3 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name=難波徳郎 kn-aut-sei=難波 kn-aut-mei=徳郎 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Wuhan University of Technology affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Photoconductivity kn-keyword=Photoconductivity en-keyword=Photovoltage kn-keyword=Photovoltage en-keyword=Persistent photoconductivity kn-keyword=Persistent photoconductivity en-keyword=CdO-Bi(2)O(3)-Al(2)O(3) glasses kn-keyword=CdO-Bi(2)O(3)-Al(2)O(3) glasses en-keyword=Electronic state kn-keyword=Electronic state END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=131 end-page=145 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=19990226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Growth, Yield and Mineral Composition of Three Rice Varieties Cultivated under Salt-Affected Conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=A pot experiment was conducted to study the relative performance of IR 6,KS 282 and IR 10198-66-2 rice varieties cultivated under salt-affected conditions at EC of 6.0,9.0 12.0 dS m(-1) in a sandy clay loam soil havig ECe of 1.6 dS m(-1) treated as control. Six seedlings of 39-day old transplaned to each pot having 12 kg soil. The fertilizer as nitrophos and potassium sulphate at the rate of 57.0, 25.0 and 50.0 mg N,P and K kg(-1) soil respectively was applied at the time of transplanting while zinc sulphate at the rate of 5 mg Zn kg(-1) soil and 43.0 mg N kg(-1) of soil as additional dose were applied 19 and 30 days after transplanting respectively. Normal plant protection measures like number of tillers, panicles, paddy grains, filled and unifilled grains, yield per plant and sterility were recorded and shoot and straw samples were analysed for sodium, potassium, calcium and chloride contents. It was observed that growth and yield of all the varieties were reduced significantly with increasing soil salinity. Na/K and Na/Ca rations in shoot and straw increased significantly with increasing soil salinity. It was also observed that higher values of Na/K and Na/Ca rations in shoots affected growth parameters while higher values of these rations in straw affected yield components and grain yield. However, IR 6 having relatively lower values of Na/K and Na/Ca rations proved to be the most salt-tolerant rice among the three varieties studied. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KambohMaqsood Ahmed kn-aut-sei=Kamboh kn-aut-mei=Maqsood Ahmed aut-affil-num=1 ORCID= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=2 ORCID= en-aut-name=AdachiTadashi en-aut-sei=Adachi en-aut-mei=Tadashi kn-aut-name=足立忠司 kn-aut-sei=足立 kn-aut-mei=忠司 aut-affil-num=3 ORCID= en-aut-name=NariokaHajime en-aut-sei=Narioka en-aut-mei=Hajime kn-aut-name=成岡市 kn-aut-sei=成岡 kn-aut-mei=市 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=soil salinity kn-keyword=soil salinity en-keyword=growth and yield kn-keyword=growth and yield en-keyword=mineral compasition kn-keyword=mineral compasition en-keyword=rice varieties kn-keyword=rice varieties END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=119 end-page=130 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=19990226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Water Table Recession in Subsurface Drained Soils en-subtitle= kn-subtitle= en-abstract= kn-abstract=Theoretical drainage equations are intensively tested in many parts of humid and arid regions and are commonly used in drainage design. However, this is still a great concern in Japan as the drainage design is exclusively based on local experiences and empirical basis. There is a need therefore to evaluate the theoretical drainage equations under Japanese field conditions to recommend equations for design of subsurface drainage systems. This was the main motivation for this study. While drainage requirements of different crops are difficult to define quantiatively, adequate drainage can probably be provided by designing for a given water table recession rate. The method used was to measure the rate of water table recession and drain outflow after cessation of a considerable amount of rainfall. Based on these measurements, soil parameters were determined and nine drainage equations were tested in simulating water table recession against actual field data of two drained experimental sites, located in Soja city west of Okayama prefecture, Japan, having drain spacing of 10 and 8.5 m for a period of two years. An experimental drainage equation was also derived and theoretical equations were recommended for design of subsurface drainage systems. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=MoustafaMahmoud Mohamed kn-aut-sei=Moustafa kn-aut-mei=Mahmoud Mohamed aut-affil-num=1 ORCID= en-aut-name=YomotaAtsushi en-aut-sei=Yomota en-aut-mei=Atsushi kn-aut-name=四方田穆 kn-aut-sei=四方田 kn-aut-mei=穆 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Simulation kn-keyword=Simulation en-keyword=Soil parameters kn-keyword=Soil parameters en-keyword=Subsurface drainage kn-keyword=Subsurface drainage en-keyword=Water table kn-keyword=Water table END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=101 end-page=118 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=19990226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Environmental Symbiosis in Urban ane Regional Infrastructure Improvement -Some Examples in Okayama Region kn-title=都市地域整備と環境共生―岡山県における事例研究 en-subtitle= kn-subtitle= en-abstract=Now it is an important theme in the urban policy to revive natural and living environment surrouding city and to reconstruct softhearted city to human and environment.

These types of failure are considered to be in close relation to the dynamic behavior of bed material around the structures. Failure of bridges due to the phenomenon of scouring around piers is a common, natural problem of river hydraulics. Experiments were carried out to investigate the characteristics of pore water pressure and effective stresses in the bed material around a circular bridge pier under abrupt change of water pressure. A laboratory model was used to clarify the effect of the variation of water pressure to determine the mechanism of the collapse of circular bridge pier during flood or storm waves. The experimental results showed that the bed material under suddeen change in drop of water pressure near the pier was weakenend by an increase in excess pore pressure, followed by a considerable quick removal of bed material. en-copyright= kn-copyright= en-aut-name=NagoHiroshi en-aut-sei=Nago en-aut-mei=Hiroshi kn-aut-name=名合宏之 kn-aut-sei=名合 kn-aut-mei=宏之 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=MiaFaruque kn-aut-sei=Mia kn-aut-mei=Faruque aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Pore pressure kn-keyword=Pore pressure en-keyword=Effective stress kn-keyword=Effective stress en-keyword=Abrupt water pressure change kn-keyword=Abrupt water pressure change en-keyword=Scour kn-keyword=Scour en-keyword=Bridge pier kn-keyword=Bridge pier END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=81 end-page=92 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=19990226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=In situ determination of field-saturated hydraulic conductivity of subsurface soil of vadose zone by technique of Pressure Infiltrometer en-subtitle= kn-subtitle= en-abstract= kn-abstract=For reducing or bridging gap between small scale laboratory investigations and large scale field investigations, a simple and portable model which is based on real situation and has a compatibility to laboratory core sampling, the pressure infiltrometer technique is introduced for determination of field-saturated hydraulic conductivity. The field -saturated hydraulic conductivity, K(FS), is obtained from measurements of steady flow rates applying constant head as well as falling head principle. The device is also used for field core sampling on which laboratory constant head as well as falling head tests is carried out. The field device is validated through comparison to laboratory core sample experiment and other existing methods. This paper describes first time a versatile field device representing good performance for in situ determination of hydraulic parameters in a short time. en-copyright= kn-copyright= en-aut-name=KohnoIchiro en-aut-sei=Kohno en-aut-mei=Ichiro kn-aut-name=河野伊一郎 kn-aut-sei=河野 kn-aut-mei=伊一郎 aut-affil-num=1 ORCID= en-aut-name=TakeshitaYuji en-aut-sei=Takeshita en-aut-mei=Yuji kn-aut-name=竹下祐二 kn-aut-sei=竹下 kn-aut-mei=祐二 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=Mohammad JafarAli kn-aut-sei=Mohammad Jafar kn-aut-mei=Ali aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=In-situ test kn-keyword=In-situ test en-keyword=Field-saturated Hydraulic conductivity kn-keyword=Field-saturated Hydraulic conductivity en-keyword=Matric flux potential kn-keyword=Matric flux potential en-keyword=Wetting front kn-keyword=Wetting front en-keyword=3D-flow kn-keyword=3D-flow END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=77 end-page=80 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=19990226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hilbert C* -bimodules and countably infinite continuous graphs en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this paper, we contruct Hilbert C* -bimodules for continuous graphs whose vertexes are countable 1-dimensiona tori, and show some uniquness property of the C* -representatiion of these bimodules. en-copyright= kn-copyright= en-aut-name=KajiwaraTsuyoshi en-aut-sei=Kajiwara en-aut-mei=Tsuyoshi kn-aut-name=梶原毅 kn-aut-sei=梶原 kn-aut-mei=毅 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 en-keyword=Hilbert bimodule kn-keyword=Hilbert bimodule en-keyword=C* -algebras kn-keyword=C* -algebras en-keyword=continous graph kn-keyword=continous graph END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=57 end-page=75 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=19990226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Statistical threshold model and radiosensitivity on binary data of radiation related cataract and epilation en-subtitle= kn-subtitle= en-abstract= kn-abstract=An analytic approach that provides explicit estimates of risk on cataract and epilation data is evaluated by reasonableness of conceivable relative risk models regarding a simple, odds, logistic or Gompertz regression method, assuming a binomial distribution. In these analyses, we apply relative risk models with two thresholds between epilators and nonepilators from a highly characteristic lesion of which radiation cataract does not occur around 2 gray for a single acute exposure. The risk models are fitted to the data assuming 10 as a constant relative biological effectiveness of neutron. The likelihood of observing the entire data set in these models fitted is evaluated by an individual binary-response array. Estimation of a threshold with or without severe epilation and the 100(1-α )% confidence limits are derived from the maximum likelihood approach. The relative risk model with two thresholds can be expressed as a formula with structure of Backgroun × RR, where RR includes threshold models with or without epilation. The radiosensitivity of ionizing radiation to cataracts has been examined for the relationship between epilators and nonepilators. en-copyright= kn-copyright= en-aut-name=OtakeMasanori en-aut-sei=Otake en-aut-mei=Masanori kn-aut-name=大竹正徳 kn-aut-sei=大竹 kn-aut-mei=正徳 aut-affil-num=1 ORCID= en-aut-name=TanakaYutaka en-aut-sei=Tanaka en-aut-mei=Yutaka kn-aut-name=田中豊 kn-aut-sei=田中 kn-aut-mei=豊 aut-affil-num=2 ORCID= en-aut-name=TomitaMakoto en-aut-sei=Tomita en-aut-mei=Makoto kn-aut-name=冨田誠 kn-aut-sei=冨田 kn-aut-mei=誠 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=radiation cataract kn-keyword=radiation cataract en-keyword=threshold model kn-keyword=threshold model en-keyword=profile approach kn-keyword=profile approach en-keyword=risk model kn-keyword=risk model en-keyword=radiosensitivity kn-keyword=radiosensitivity END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=37 end-page=55 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=19990226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analysis of non-stationary spatial data : A study on the performances of Universal Kriging, Median-Polish Kriging and LOESS en-subtitle= kn-subtitle= en-abstract= kn-abstract=One of major problems in spatial analysis is to estimate the value z(s(0)) at an unknown location s(0) using the information about observations z(s(α)), α = 1,…,n. In this article, we will perform a numerical study about some methods for this problem. That is, we examine both the tranditional statistical method which does not take into account spatial correlation and the spatial statistical method which takes into account spatial correlation by applying them to a set of non-stationary spatial data. We compare the predictive powers of these methods. More precisely, we choose Universal Kriging(UK) and Median-Polish Kriging(MPK) as spatial statistical methods, and locally weighted regression or LOESS as a traditional method. As the major criterion for comparison, we use the so-called PRESS statistic, and also draw the prediction surface plot and the prediction standard error surface plot as minor criteria. A real numerical example of non-stantionary spatial data is analyzed for the comparison among the above three methods. en-copyright= kn-copyright= en-aut-name=ChoiSeung Bae en-aut-sei=Choi en-aut-mei=Seung Bae kn-aut-name=崔承培 kn-aut-sei=崔 kn-aut-mei=承培 aut-affil-num=1 ORCID= en-aut-name=TanakaYutaka en-aut-sei=Tanaka en-aut-mei=Yutaka kn-aut-name=田中豊 kn-aut-sei=田中 kn-aut-mei=豊 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=Stationary kn-keyword=Stationary en-keyword=Variogram kn-keyword=Variogram en-keyword=UK kn-keyword=UK en-keyword=MPK kn-keyword=MPK en-keyword=LOESS kn-keyword=LOESS END start-ver=1.4 cd-journal=joma no-vol=4 cd-vols= no-issue=1 article-no= start-page=19 end-page=35 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=19990226 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Assessment of Local Influence in Statistical Modelling with Equality Constraints kn-title=等式制約を含む統計モデルにおける局所影響の評価 en-subtitle= kn-subtitle= en-abstract=Influence analysis in the sense of Cook (1986)'s local influence is derived for statistical modelling with equality constraints.

There were no substantial changes at the area of the cultivated acreage and the use level of arable land before World War II. In statistics after 1965, the use level of the cultivated acreage and arable land has decreased remarkably. In this point, it is clearly observed that the cultivated acreage in 2005 has decreased by 60 percent compared with 1960 and the area of the field has importantly decresed in the same period about 80 percent. In addition, the uncultivated arable land in 2005 has increased double (or more) compared with 1975. Finally, this analysis concretely illustrated decreasing of man's concern for the production of food. Because a part of the safety of food is threatened recently, it is important in above all to procure food safely. Moreover, to reinforce a domestic production of food the decision and the execution of an effective policy are requested. en-copyright= kn-copyright= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name=市南文一 kn-aut-sei=市南 kn-aut-mei=文一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 en-keyword=arable land use kn-keyword=arable land use en-keyword=planted acreage kn-keyword=planted acreage en-keyword=food production kn-keyword=food production en-keyword=Okayama prefecture kn-keyword=Okayama prefecture END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=23 end-page=28 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20090316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Laboratory Investigation of Ethanol/Bentonite Slurry Grouting into Rock Fractures: Preliminary Resalts en-subtitle= kn-subtitle= en-abstract= kn-abstract=During underground space development, groundwater seepage mostly occurs which may seriously affect the stability of deep excavations as well as retard progress of construction. For smooth progress of work, effective construction and operation of a disposal facility for high level radioactive waste (HLW), it is important to control seepage into excavations by sealing off fractures or fissures and excavation disturbed zones (EDZ) to control groundwater inflow during the construction phase of such a facility. In this study, a series of experiments were conducted on ethanol/bentonite slurries in the laboratory with the aim of determining the effect of a hydrophilic solvent such as ethanol on the hydraulic and injection characteristic of bentonite slurry for the sealing of fissures to control ground water seepage during the construction phase of a repository. Preliminary results revealed ethanol/bentonite slurry as an effective grouting material capable of penetrating micro fractures (100μm or less) and with the permeability of the grouted medium being as low as 10E-7cm/s. The results also show that the effectiveness and efficiency of grouting is dependent on the type of injection and fissure size. Dynamic injection was observed to be efficient as it was able to inject high dense slurry. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=ChegbelehLarry Pax kn-aut-sei=Chegbeleh kn-aut-mei=Larry Pax aut-affil-num=1 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=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=AkudagoJohn Apambilla kn-aut-sei=Akudago kn-aut-mei=John Apambilla aut-affil-num=3 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=AlimMd.

It is believed that when groundwater level is less than 2 m there is the possibility of salinity transfer between the soil and groundwater due to factors such as capillary forces. One-dimensional column tests were conducted in the laboratory to find a suitable capillary cut design. The capillary cut material comprised a 20 cm thick 2?4.7 mm and a combination of 2?4.7 mm and 9.5?19 mm gravel material. In all, four different designs were tested by compacting Oji sand in the various columns. Groundwater level of 0.75 m from the top was maintained while salt solution of 10% concentration was allowed to flow under capillary forces through the columns. The water content in the columns were monitored using frequency domain reflectrometry-vector analyzer (FDR-V) after which soil samples from 10 m interval in each column was taken for electrical conductivity measurements. The results showed that 5 cm thick, 2?4.7 mm gravel sandwiching coarser material (e.g. 5 cm thick 9.5?19 mm or 10 cm thick 9.5?19 mm gravel material) proved to be very useful design to cut capillarity. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=AkudagoJohn Apambilla kn-aut-sei=Akudago kn-aut-mei=John Apambilla aut-affil-num=1 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=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=ChegbelehLarry Pax kn-aut-sei=Chegbeleh kn-aut-mei=Larry Pax aut-affil-num=3 ORCID= en-aut-name=KomatsuMitsuru en-aut-sei=Komatsu en-aut-mei=Mitsuru kn-aut-name=小松満 kn-aut-sei=小松 kn-aut-mei=満 aut-affil-num=4 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=AlimMd.

Determination of SWCC is not easy and more so time consuming. Generally, ceramic disc with high air-entry value has been used in the pressure plate apparatus for this purpose by many people. Now-a-days membrane filter is being used as a suitable alternative to ceramic disc. However, experience shows, it has disadvantage of breakage after one time use especially with coarse grain soils (sandy soils). In this study, membrane filter with stainless wire mesh was used to solve this problem and the SWWC was compared with the results obtained without wire mesh. Results showed that membrane filter with stainless wire mesh can be used to determine the SWCC for coarse grain soils. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=AlimMd.

The "Pandemic Influenza Preparedness Action Plan" determines the strategy against an influenza pandemic in Japan. Simulations were carried out using an individual based model (IBM). The IBM targeted a virtual area with a population of 100,000 using the demographic data of Sapporo-city, Hokkaido. The effectiveness of targeted antiviral prophylaxis (TAP), geographical targeted antiviral prophylaxis (GTAP), school closure, and pre-pandemic vaccination were explored. Moreover, this study focused on infections among children, who have a high attack rate, and analyzed the effectiveness of interventions for school-age targeted antiviral prophylaxis (STAP). Consequently, TAP, which is recommended by the "Pandemic Influenza Preparedness Action Plan", was found to have high effectiveness in the suppression of the outbreak. Moreover, this study showed the importance of intervention among children, such as STAP and school closure, to prevent the spread of H5N1 influenza. en-copyright= kn-copyright= en-aut-name=MorimotoTomoko en-aut-sei=Morimoto en-aut-mei=Tomoko kn-aut-name=森本智子 kn-aut-sei=森本 kn-aut-mei=智子 aut-affil-num=1 ORCID= en-aut-name=ZenihanaTomohiro en-aut-sei=Zenihana en-aut-mei=Tomohiro kn-aut-name=銭花知弘 kn-aut-sei=銭花 kn-aut-mei=知弘 aut-affil-num=2 ORCID= en-aut-name=MaitaniYusuke en-aut-sei=Maitani en-aut-mei=Yusuke kn-aut-name=米谷祐介 kn-aut-sei=米谷 kn-aut-mei=祐介 aut-affil-num=3 ORCID= en-aut-name=IshikawaHirofumi en-aut-sei=Ishikawa en-aut-mei=Hirofumi kn-aut-name=石川洋文 kn-aut-sei=石川 kn-aut-mei=洋文 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=Influenza kn-keyword=Influenza en-keyword=Pandemic kn-keyword=Pandemic en-keyword=H5N1 kn-keyword=H5N1 en-keyword=Individual Based Model (IBM) kn-keyword=Individual Based Model (IBM) en-keyword=Sapporo kn-keyword=Sapporo END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue= article-no= start-page=28 end-page=33 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=200612 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on optical properties of SnO-based glasses as lead-free glasses kn-title=SnOベースガラスの鉛代替光学ガラスへの応用の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The preparation of SnO-SiO(2), SnO-B(2)O(3), and SnO-GeO(2) glasses by melting in air was performed.

B(2)O(3) was added to blast furnace slag to promote the phase separation. The slag glasses were heat-treated above glass transition temperatures. The slag glass prepared from blast furnace slag gelled after the heat treatment and the subsequent three types of acid treatment. The ratios of SiO(2) component in the gels were 40 ? 60mass%. On the other hand, phase separation was observed on the surface of the slag glasses prepared from pre-treated slag by 2.5N HCl after the heat treatment. After soaking in acid, they did not gel and changed to insoluble colorless solids. According to compositional analyses, it was found that the insoluble colorless solids contained 70 - 90mass% SiO(2). No colored ions such as Cr, Mn, and Fe were confirmed in the remaining insolubles by optical absorption measurement. Therefore, the colorless silica-rich solids were successfully obtained in the present process. The end products obtained in the present process are expected as material of glass. en-copyright= kn-copyright= en-aut-name=SakidaShinichi en-aut-sei=Sakida en-aut-mei=Shinichi kn-aut-name=崎田真一 kn-aut-sei=崎田 kn-aut-mei=真一 aut-affil-num=1 ORCID= en-aut-name=MikamiSyuuhei en-aut-sei=Mikami en-aut-mei=Syuuhei kn-aut-name=三上修平 kn-aut-sei=三上 kn-aut-mei=修平 aut-affil-num=2 ORCID= en-aut-name=NanbaTokuro en-aut-sei=Nanba en-aut-mei=Tokuro kn-aut-name=難波徳郎 kn-aut-sei=難波 kn-aut-mei=徳郎 aut-affil-num=3 ORCID= en-aut-name=MiuraYoshinari en-aut-sei=Miura en-aut-mei=Yoshinari kn-aut-name=三浦嘉也 kn-aut-sei=三浦 kn-aut-mei=嘉也 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学保健環境センター環境安全部門 affil-num=2 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 affil-num=3 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 affil-num=4 en-affil= kn-affil=岡山大学環境理工学部環境物質工学科 en-keyword=Blast furnace slag kn-keyword=Blast furnace slag en-keyword=Recycling kn-keyword=Recycling en-keyword=Colorless silica-rich solids kn-keyword=Colorless silica-rich solids en-keyword=Phase separation kn-keyword=Phase separation en-keyword=Glass kn-keyword=Glass END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue= article-no= start-page=39 end-page=44 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200812 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=鉛フリー光学ガラスとしてのSnO-B(2)O(3)ガラスの光学特性 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The preparation of SnO-B(2)O(3) and SnO-SiO(2) glasses by melting in Ar atomosphere was performed.

Therefore, it is necessary to estimate the NAPL content (θNAPL) in unsaturated soil to detect and monitor the NAPL contaminations in soil and groundwater. The objective of this study was to investigate the relationship between θNAPL and permittivity (K) in unsaturated sandy soil as a fundamental study to estimate the θNAPL. An ADR (Amplitude Domain Reflectometry) method was used to measure the K in the soil including the NAPL which was a castor oil as light NAPL or a HFE-7100 as dense NAPL. The experimental study indicated the linear relation between θNAPL and K in unsaturated soil with soil-NAPL-air. Using this relationship, we can estimate the θNAPL. On the other hand, although we obtained the relationship between θNAPL, θw and (root) K in unsaturated soil with soil-NAPL-water-air, it was not possible to estimate the θNAPL using this relationship. en-copyright= kn-copyright= en-aut-name=MoroizumiToshitsugu en-aut-sei=Moroizumi en-aut-mei=Toshitsugu kn-aut-name=諸泉利嗣 kn-aut-sei=諸泉 kn-aut-mei=利嗣 aut-affil-num=1 ORCID= en-aut-name=SasakiYumi en-aut-sei=Sasaki en-aut-mei=Yumi kn-aut-name=佐々木裕美 kn-aut-sei=佐々木 kn-aut-mei=裕美 aut-affil-num=2 ORCID= en-aut-name=MiuraTakeshi en-aut-sei=Miura en-aut-mei=Takeshi kn-aut-name=三浦健志 kn-aut-sei=三浦 kn-aut-mei=健志 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 環境理工学部 環境管理工学科 affil-num=2 en-affil= kn-affil=日化エンジニアリング株式会社 affil-num=3 en-affil= kn-affil=岡山大学 環境理工学部 環境管理工学科 en-keyword=NAPL kn-keyword=NAPL en-keyword=Permittivity kn-keyword=Permittivity en-keyword=Amplitude Domain Reflectmetry kn-keyword=Amplitude Domain Reflectmetry en-keyword=Soil and groundwater contamination kn-keyword=Soil and groundwater contamination 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=2008 dt-pub=20080325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=地方都市における中心商業地の衰退化と再生への課題 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=NaniwadaTakao en-aut-sei=Naniwada en-aut-mei=Takao kn-aut-name=難波田隆雄 kn-aut-sei=難波田 kn-aut-mei=隆雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=20070930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=船底防汚剤の生態毒性と環境リスクに関する研究 kn-title=Studies on the ecotoxicity and ecological risks of antifouling chemicals en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=KoutsaftisApostolos en-aut-sei=Koutsaftis en-aut-mei=Apostolos kn-aut-name=クチヤフチイスアポストロス kn-aut-sei=クチヤフチイス kn-aut-mei=アポストロス aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=125 end-page=128 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=メキシコの半乾燥地における異なる有機物の施用効果 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In semiarid areas of Mexico, lack of organic matter is a major constraint for production of corn and frijol beans, the main crops of the region. A multi-year experiment was carried out at the CENGUA Experiment Station, Guanajuato State, Mexico. Soil moisture was highest in the treatments with 100% or 67% of corn residues. Yields of frijol beans increased as the proportion of corn residues increased in all three years, but there was no significant difference between the treatment with all corn residues and the treatment with one-third reduction of corn residues in two of the three years. The harvest index was highest in the same two treatments with higher proportions of corn residues in the last years. These results suggest that corn residues can be reduced by one third in fertilization of corn-frijol bean systems while maintaining adequate frijol bean yields. This could assist in establishment of sustainable corn-frijol bean-cattle integrated agriculture in semi-arid areas of Mexico. en-copyright= kn-copyright= en-aut-name=DanHaruyuki en-aut-sei=Dan en-aut-mei=Haruyuki kn-aut-name=團晴行 kn-aut-sei=團 kn-aut-mei=晴行 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=GarciaRamon Aguilar kn-aut-sei=Garcia kn-aut-mei=Ramon Aguilar aut-affil-num=2 ORCID= en-aut-name=HayashiYukihiro en-aut-sei=Hayashi en-aut-mei=Yukihiro kn-aut-name=林幸博 kn-aut-sei=林 kn-aut-mei=幸博 aut-affil-num=3 ORCID= en-aut-name=AgoHideo en-aut-sei=Ago en-aut-mei=Hideo kn-aut-name=吾郷秀雄 kn-aut-sei=吾郷 kn-aut-mei=秀雄 aut-affil-num=4 ORCID= en-aut-name=AdachiTadashi en-aut-sei=Adachi en-aut-mei=Tadashi kn-aut-name=足立忠司 kn-aut-sei=足立 kn-aut-mei=忠司 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=独立行政法人緑資源機構海外事業部 affil-num=2 en-affil= kn-affil=メキシコ国国立農牧林研究所 affil-num=3 en-affil= kn-affil=日本大学 affil-num=4 en-affil= kn-affil=農林水産省中国四国農政局高瀬農地保全事業所 affil-num=5 en-affil= kn-affil=岡山大学 en-keyword=compost kn-keyword=compost en-keyword=corn residues kn-keyword=corn residues en-keyword=frijol beans kn-keyword=frijol beans en-keyword=soil moisture kn-keyword=soil moisture END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=121 end-page=124 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel Fluorescent Probe Based on Anthryl Dendron Having Oligo(ethyleneoxide) Groups at the Terminals en-subtitle= kn-subtitle= en-abstract= kn-abstract=Amphiphilic anthryl dendrons 5 and 6, which have carboxylate groups or oligo(ethyleneoxide) groups at the terminals, show solvatochromic properties.

To elucidate the effect of P-stress on plant growth, and P-efficiency under Pstarvation, 14 diverse Brassica cultivars were grown hydroponically in a climatically controlled chamber using sufficient (200 and 400 μM) and stress (10 and 20 μM) P-levels using ammonium phosphate (NH4H2PO4) as a P source. Cultivars showed differential growth behaviour in terms of biomass accumulation (shoot and root dry matter partitioning), percent distribution of Pi-concentration ([P]) and P-contents in plant parts (roots and shoots), and P-efficiency ratio (% PER)(relative shoot growth) indicating considerable genetic diversity among the tested Brassica cultivars. PER and the proportional increases in shoot dry matter (SDM) accumulation (SDMmax/SDMmin) in response to the P levels assisted in categorizing the cultivars into efficient and inefficient utilizers of the absorbed P from an ambient environment. Cultivars were classified into efficient responsive (ER), efficient non-responsive (ENR), non-efficient responsive (NER) and non-efficient non-responsive (NENR) by plotting ordination plots between PER and SDMmax/SDMmin under P-stress environment. Differential PER values at stress P levels corresponds to high P levels suggest that P efficiency mechanisms can be different from one cultivar to another within a give plant species and cultivars exhibiting high PER values are better choice to thrive under P-starvation. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=AkhtarM.Shahbaz kn-aut-sei=Akhtar kn-aut-mei=M.Shahbaz aut-affil-num=1 ORCID= en-aut-name=OkiYoko en-aut-sei=Oki en-aut-mei=Yoko kn-aut-name=沖陽子 kn-aut-sei=沖 kn-aut-mei=陽子 aut-affil-num=2 ORCID= en-aut-name=AdachiTadashi en-aut-sei=Adachi en-aut-mei=Tadashi kn-aut-name=足立忠司 kn-aut-sei=足立 kn-aut-mei=忠司 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=University of Agriculture affil-num=2 en-affil= kn-affil=Okayama University affil-num=3 en-affil= kn-affil=Okayama University en-keyword=Brassica cultivars kn-keyword=Brassica cultivars en-keyword=biomass and P-distribution kn-keyword=biomass and P-distribution en-keyword=P-contents kn-keyword=P-contents en-keyword=P-efficiency ratio kn-keyword=P-efficiency ratio END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=103 end-page=109 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Basic Slag, Aggregate Size and Groundwater Treatments on the Production of Chilli in Acid Sulfate Soils in a Simulation Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=A simulation study was conducted to evaluate the effects of basic slag (BS10 and BS20: basic slag 10 and 20 t ha-1), aggregate size (A20 and A30: aggregate sizes of soil, less than 20 and 20-30 mm) and groundwater depth (Gw0: no influence of groundwater and Gw50: groundwater beneath 50 cm of the soil surface) as physico-chemical amendments in two pre-leached (leached for a week through tap water to remove excessive acidity and salinity from the soil before transplantation) acid sulfate soils of Badarkhali (Salidic Sulfaquept) and Cheringa (Typic Sulfic Halaquept) series in relation to the production of Chilli (Capsicum annum L.). Maximum growth and yield of chilli were recorded by the treatment combining A30Gw50BS20 in both the Cheringa (green chilli weight: 4.82 t ha-1) and Badarkhali (4.51 t ha-1) soils. The application of basic slag (BS20) was found to be the most effective among the individual treatments, followed by the BS10 > A30 > Gw50 treatments. The application of BS20 increased the yield in combination with the Gw0 treatment by 40% for A20, while by 107% for A30 in the Badarkhali soil. On the other hand, in the case of Gw50, these increments were 49 and 141% for A20 and A30, respectively. The application of BS at the highest rate (BS20) to the Cheringa soil was more effective compared with the A20 and A30 treatments in the Badarkhali soil. The same rate of BS20 in combination with the Gw50 treatment increased the yield by 59 to 147% in the Cheringa soil compared with 49 to 141% in the Badarkhali soil. Almost similar and significant (p?0.05) effects were observed for the other growth parameters of chilli cultivated in both soil series. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KhanMd.

Accordingly, the present study was conducted for the Enumeration, isolation and identification of nitrogen fixing bacterial strains at seedling stage (30 days after seed sowing) in rhizosphere of rice (BR 10, Oryza sativa L.) grown in Non-Calcareous Grey Flood Plain soil of Bangladesh. The soil is classified as ‘Inceptisol’ order and ‘Aquept’ suborder. It was identified as ‘Dhamrai series’, had ‘silt’ texture, pH 7.1 and 5.5 C/N ratio. The present results of the microbial tests on the rice rhizosphere soil evinced that out of 263 isolates, only 91 were branded as nitrogen fixing organisms per gram of soil, which was about 34.6 % of the total isolates. As per selection criteria, four individual strains were considered for identification. Biochemical tests were conducted for proper identification and the selected strains were identified as Enterobacter spp., Klebsiella spp., Bacillus spp. and Azospirllum spp. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KhanMd.

The soil showed a silty clay loam texture, initial pH value of 4.1, pyrite content of 55 g kg-1, base saturation of 47%, ECe value of 3.6 dS m-1, high exchangeable Fe3+ and Al3+ contents of 1.47 and 5.29 cmolc kg-1, respectively. The pH value of the average soil data obtained from all the treatments during fruit set (95 days after transplantation) of eggplants was found to be increased in pH by 1.2 units higher compared with the control (i.e. initial pH value). The contents of P, K, Ca and Mg in the average soil data during fruit set were found to be increased (IOC = increased over control) by 41 to 127% IOC, while the contents of Al3+, Fe3+, Na+, Cl- and SO4 2- in the soil were found to be decreased by 28 to 92% IOC. The different treatments on eggplants grown under the modified-plain-ridge-ditch techniques in the Cheringa acid sulfate soil significantly (0?0.05) increased the fresh yield of eggplants, and the increment was more pronounced with Tech 2. The maximum yield of 17.8 t ha-1 of eggplant for Tech 1 and 20.1 t ha-1 for Tech 2 were recorded by the application of BS30 in the soils of smaller aggregates (A20) at the ridges of Tech 2, followed by the A30BS30 treatments in both the techniques. The lowest quantity of 1.7 t ha-1 yield was recorded by the control treatment. The eggplants grown in the ridges of both the techniques exhibited the best responses on N, P, K, Ca and Mg contents in eggplant tissues during fruit set. As expected, the lowest contents of these nutrients in the eggplants were recorded in the control treatment. Sulfur content of the eggplants grown in the control plots was 3.6 g kg-1 and was in the range of adequate S content (4 g kg-1). However, the S contents in the eggplants grown in different treatments were significantly (p?0.01) lower compared with the adequate level. The effectiveness of the treatments for the reclamation of the soil in relation to the growth of eggplants was: Tech 2 > Tech 1, BS30 > BS20, and A20 > A30. The results suggest that the physicochemical properties of the soil, and the growth, yield and nutrition of eggplants were strikingly improved by the application of flash leaching followed by BS30 and A20 treatments in the ridges of Tech 2, and are regarded as the best reclamation measures for this acid sulfate soil. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KhanMd.

Although Muscat cultivation in glasshouse was already been introduced in the 19th century, grape production had remarkably increased up to mid-20th century. After various kinds of grapes such as Neo-Muscat and Campbell Early have been cultivated, it has come to concentrate on the production of Pioniere in Okayama prefecture. The cultivated area of grapes is, however, decreasing gradually due to aging in the farm labor force and the lack of agricultural successors. In the light of the investigations, this research subsequently stated the outline and the transition of the grape production with the exsisting statistical materials etc. en-copyright= kn-copyright= en-aut-name=IchiminamiFumikazu en-aut-sei=Ichiminami en-aut-mei=Fumikazu kn-aut-name=市南文一 kn-aut-sei=市南 kn-aut-mei=文一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 en-keyword=grape production kn-keyword=grape production en-keyword=grape varieties kn-keyword=grape varieties en-keyword=Pioniere kn-keyword=Pioniere en-keyword=Okayama prefecture kn-keyword=Okayama prefecture END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=67 end-page=74 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neutralizing Capacity of Basic Slag in Acid Sulfate Soils and Its Impacts on the Solubility of Basic Cations under Various Moisture Regimes en-subtitle= kn-subtitle= en-abstract= kn-abstract=An incubation study was conducted with the topsoils (depth: 0-20 cm) of two different series namely Cheringa (silty clay loam, pHwater 3.6, electrical conductivity = EC 18.5 dS m-1, CEC 17.2 c mol kg-1, organic matter = OM 39.1 g kg-1, and Badarkhali (silty clay loam, pHwater 3.9, EC 19.0 dS m-1, CEC 18.40 c mol kg-1, OM 30.7 g kg-1) acid sulfate soils to evaluate the effectiveness of basic slag (BS) for the neutralization of acidity and solubility of basic cations. These soils received BS at the rate of 0, 11, 22 and 33 t ha-1 under various moisture regimes (moisture at saturated condition, i.e. 100 % moisture, moisture at field condition, i.e. 50 % and wetting-drying cycles of those 50 and 100 % moisture levels). The impacts of these treatments on some selected properties and changes in water soluble bases in these soils were studied at different periods of 180 days of incubation. The application of BS was found to be increased the pH of soils from 3.6 to 5.1 for Cheringa; 3.9 to 5.2 for Badarkhali soils during the 180 days of incubation. These increments were more striking with the highest doses of BS at 33 t ha-1 under saturated moisture conditions in both the soils. The EC of the soils had not much influenced by the application of BS, regardless of time. The treatments were exerted significant (p?0.05) effects on the solubility of basic cations in different periods of incubation. The maximum release of the bases were recorded during 180 days of incubation under saturated moisture condition and the findings will be supportive for planning of crop production on these soils. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=Md.

This method is also useful to prospect the areas of interest in regional monitoring of a surface variable. The spatial scan statistic (Kulldorff, 1997) is a method of detection and inference for the zones of significantly high or low rates based on the likelihood ratio. These zones are called hotspots. The purpose of this paper is to detect the hotspot area for spatial data using echelon. We perform echelon analysis for Korea earthquake data. We use ESRI’s ArcGIS that is geographical information system (GIS) software to make the meshed areas and get contiguity information of these areas. With this contiguity information on the meshed areas, we detect the hotspot area using echelon analysis and spatial scan statistics. In addition, we compare with the result of analysis based on the total of number of times simply and the seismic wave energy. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=SanghoonHan kn-aut-sei=Sanghoon kn-aut-mei=Han aut-affil-num=1 ORCID= en-aut-name=IshiokaFumio en-aut-sei=Ishioka en-aut-mei=Fumio kn-aut-name=石岡文生 kn-aut-sei=石岡 kn-aut-mei=文生 aut-affil-num=2 ORCID= en-aut-name=KuriharaKoji en-aut-sei=Kurihara en-aut-mei=Koji kn-aut-name=栗原考次 kn-aut-sei=栗原 kn-aut-mei=考次 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=Hotspot kn-keyword=Hotspot en-keyword=Echelon analysis kn-keyword=Echelon analysis en-keyword=Spatial scan statistics kn-keyword=Spatial scan statistics en-keyword=Seismic Wave Energy kn-keyword=Seismic Wave Energy END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=43 end-page=49 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200803 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Estimate of the posted land price in Okayama city and its visualizing system kn-title=岡山市における地価公示価格の推定とその表示システムについて en-subtitle= kn-subtitle= en-abstract= kn-abstract=The posted land price is a decrared land price from Land Appraisal Committee, and current market price is selling price of the market.

However, public opposition occurs for the construction because the final waste disposal site has negative image such as pollution of various kinds, increase of traffic volume and noise by truck and bulldozer, and aggravation of living conditions. Public opposition is the most critical problem in constructing final waste disposal site. The source of public opposition has been characterized as NIMBY or not-in-my-yard.

Individuals have personal information, behavior patterns, and interactions among social groups. We took into consideration the influence of residual immunity due to past vaccination. We considered Traced Vaccination (TV) and Mass Vaccination (MV) strategies against bioterrorism. We investigated the effect of TV and MV strategies on the suppression of smallpox epidemics.

A waste containment or disposal facility is required to isolate the waste from man and the biosphere to avoid any undue radiation exposure. Deep geological repository or disposal facility is considered as an effective way to isolate high level radioactive waste, HLW from the human environment, for which a multi ? barrier system plays a very significant role. In this paper, literature collection was carried out, aimed to overview the present knowledge about the concepts of repository for HLW and to identify technologies that are currently available in the nuclear industry worldwide and the current state of barrier technologies for hazardous waste sites. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=ChegbelehLarry Pax kn-aut-sei=Chegbeleh kn-aut-mei=Larry Pax aut-affil-num=1 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=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=AkudagoJohn Apambilla kn-aut-sei=Akudago kn-aut-mei=John Apambilla aut-affil-num=3 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=AlimMd.

First, theories up to the present about civilizations including those of Spengler and Toynbee are introduced. Second, the criterion presented by Bagby to distinguish major civilizations and peripheral civilizations are examined and proved to be subjective. Then the author proposes as an objective criterion for big civilizations just the pattern of succeeding four stages with the span of 400~500 years each. Big civilizations meeting this requirement which total eight or nine are divided into two types according to the difference of their nature. Lastly is shown how four puzzles of world history that have hitherto caused a lot of disputes (feudalism, absolute power of royalty, capitalism and modernization) can be solved through the recognition of these big civilizations. en-copyright= kn-copyright= en-aut-name=TonomuraNaohiko en-aut-sei=Tonomura en-aut-mei=Naohiko kn-aut-name=外村直彦 kn-aut-sei=外村 kn-aut-mei=直彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END
