This article discusses dynamics of the automobile industry, one of the highest growth manufacturing sectors under the liberalization policy in the 1990s. After a brief historical explanation of the industry, the author describes corporate strategies of new comers, classified into three divisions; i.e. passenger car, commercial vehicle and two wheelers. Then he also analyze their distribution patterns from the view point of transport cost and Indian industrial location policy. The location of car assembly units in the 1990s tends to concentrate in greenfields on the outskirts of the existing agglomerations of the automobile industry. en-copyright= kn-copyright= en-aut-name=TomozawaKazuo en-aut-sei=Tomozawa en-aut-mei=Kazuo kn-aut-name=友澤和夫 kn-aut-sei=友澤 kn-aut-mei=和夫 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 en-keyword=automobile industry kn-keyword=automobile industry en-keyword=liberalization kn-keyword=liberalization en-keyword=industrial location kn-keyword=industrial location en-keyword=India kn-keyword=India END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=127 end-page=134 dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=19980114 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Matric Suction on Shear Characteristics of Unsaturated Fraser River Sand en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper discusses the shear strength and volume change characteristics of a loose Fraser River sand. Suction-controlled simple shear tests were carried out for the unsaturated sand. Drained tests for the saturated sand were also carried out for the comparison with the unsaturated sand. The increase of the shear strength of the sand with the matric suction is very small and there is almost no increase of that over 20 kPa of the matric suction. The suppression effect of the matric suction on the volume change bahavior during shear is small, and the degree of dilation increases with the increase of the matric suction. en-copyright= kn-copyright= en-aut-name=ShimadaKiyoshi en-aut-sei=Shimada en-aut-mei=Kiyoshi kn-aut-name=島田清 kn-aut-sei=島田 kn-aut-mei=清 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 en-keyword=unsaturated sand kn-keyword=unsaturated sand en-keyword=shear strength kn-keyword=shear strength en-keyword=simple shear test kn-keyword=simple shear test en-keyword=matric suction kn-keyword=matric suction en-keyword=volume change kn-keyword=volume change en-keyword=dilatancy kn-keyword=dilatancy END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=121 end-page=126 dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=19980114 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Comparison of micrometeorological environments inside and outside a watermelon plastic greenhouse kn-title=スイカ・ビニールハウス内外での微気象環境の比較 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The use of glass and plastic greenhouses have rapidly increased in recent years. Meteorological and soil moisture environments inside a greenhouse are significantly different from those in the open field. These differences should be understandable to establish accurate predictions of water consumption and evapotranspiraton inside a greenhouse which play impotrant roles in the design of any irrigation system. This study aims to estimate the micrometeorological conditions inside a watermelon plastic greenhouse which can be used for evapotranspiration calculations. Therefore, micrometeorological data were measured inside and outside the greenhouse for the comparison purposes. The results of this study may be summarized as : (1) Solar radiation inside the greenhouse was about 70% of that of outside it. (2) Net radiation during the daytime inside the greenhouse was almost the same as the absorbed total short-wave radiation. (3) The difference of air temperature inside and outside the greenhouse was very large during the daytime whereas not much difference was observed during the nighttime. (4) Both relative humidity and saturation deficit inside the greenhouse were higher than outside in case of highly vegetative land. (5) Wind speed inside the greenhouse was almost zero, while outside the average value was 1.8m/s. en-copyright= kn-copyright= en-aut-name=MoritaNoboru en-aut-sei=Morita en-aut-mei=Noboru kn-aut-name=森田昇 kn-aut-sei=森田 kn-aut-mei=昇 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 affil-num=2 en-affil= kn-affil=岡山大学 en-keyword=plastic greenhouse kn-keyword=plastic greenhouse en-keyword=micrometeorology kn-keyword=micrometeorology en-keyword=watermelon kn-keyword=watermelon END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=105 end-page=120 dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=19980114 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The classification of water shortage degree of irrigated plot area in command area by LP technique, Hiikawa-karyu irrigation project, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Two optimization models are formulated based on different objectives for assisting the irrigation planner in making decision on agricultural planning during drought year. The sensitive degree of water shortage area in the irrigation project are classified by those models. They are solved by simplex method. Firstly, the Two-phase method is applied to analyze the artificial variables in the formulated model. Then, the formulated model is modified after getting rid of the artificial variables to obtain the feasible solution. The agricultural planning is planned by considering the classified area with social equity and economic improvement. Crop diversification is introduced to conduct in the very sensitive water shortage area and intermittent irrigation system is introduced to operate in the moderately sensitive water shortage area. The integrated farming system, the separation of land owner and cultivator and the disposition of substitute lots system are also suggested to conduct in this study project. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KidtimontonSurasri kn-aut-sei=Kidtimonton kn-aut-mei=Surasri aut-affil-num=1 ORCID= en-aut-name=MitsunoToru en-aut-sei=Mitsuno en-aut-mei=Toru kn-aut-name=三野徹 kn-aut-sei=三野 kn-aut-mei=徹 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=agricultural planning kn-keyword=agricultural planning en-keyword=Two-phase method kn-keyword=Two-phase method en-keyword=integrated farming kn-keyword=integrated farming en-keyword=sensitive water shortage kn-keyword=sensitive water shortage en-keyword=disposition of substitute lots system kn-keyword=disposition of substitute lots system END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=97 end-page=104 dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=19980114 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surface Air Temperature Distribution : A Study from Southwest Bangladesh en-subtitle= kn-subtitle= en-abstract= kn-abstract=Surface air temperature distribution over the Ganges Delta Region of southwest Bangladesh and its tendency of warming are discussed through the analyses based upon the long-term temperature data from 1900-93. The data consist of two parts corresponding to the time-periods: 1973-93 and 1900-72. The study area is one of most affected places by the annual monsoon hydrological cycle and the present observation from these temperature data indicate that the surface air temperature gradient in the north-south direction is significant in the rainy season and that the temperature of the region is at an increasing tendency; the warming rate during the data periods (1900-93) on the long-term mean annual basis is estimated as 0.77℃ at Satkhira of the Khulna division and 0.29℃ as an areal average including the Barisal division, for the time difference of about half a century between the data periods before and after 1972. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=HassanMuhammad Qumrul kn-aut-sei=Hassan kn-aut-mei=Muhammad Qumrul aut-affil-num=1 ORCID= en-aut-name=OkuboKenji en-aut-sei=Okubo en-aut-mei=Kenji kn-aut-name=大久保賢治 kn-aut-sei=大久保 kn-aut-mei=賢治 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Department of Geology, University of Dhaka affil-num=2 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=1 article-no= start-page=75 end-page=95 dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=19980114 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Wave-Induced Pore-Pressure Response on a Submarine Pipeline Buried in Seabed Sediments - Experiment and Numerical Verification - en-subtitle= kn-subtitle= en-abstract= kn-abstract=The response on sandy seabed sediments to a harmonically oscillating water-table, with a special consideration of the wave-induced pore-pressure oscillations around a pipeline buried in seabed sediments, is studied in the present work experimentally and numerically.
