  • Seasonal and interannual variation of volume transport through the La-Perouse Strait were estimated using the difference of sea level observed at Krillion of Sakhalin, Russia, and Wakkanai of Hokkaido, Japan, during the period of 1975-1988. Historical sea level measurements between Russian and Japanese tide gauge data were normalized using an independent direct volume transport measurement. Volume transport from the East Sea (Sea of Japan) to the Sea of Okhotsk varied from -0.01 to 1.18 Sv with an annual mean value of 0.61 Sv. Monthly water transport rates showed a unimodal distribution with its maximum occurring in summer (August) and minimum in winter (December-February). The annual mean volume transport varied from 0.2 to 0.8 Sv during the period of 1975-1988 with the maximum variance of 0.6 Sv.

  • The purpose of this study was aimed to investigate the historical tends of population growth which has reflected direct effect of the ratio of food self sufficiency in Korea between the year of 1910 and 1980. Author divided the whole years between 1910 and 1980 into five different periods ; colonial period from 1910 to 1945, post colonial period from 1945 to 1950, Korean war period from 1950 to 1955, post Korean war period from 1955 to 1960, fast economic growing period 1960~1980. The ratio of national food self sufficiency has been profoundlly affected by dual factors ; rate of population group and increment of GNP which reflect the national economic development. Total food production never reached the level of population growth ratio in Korea. As a result food demand and supply has shown imbalaced condition which leads to import foods from outside contury to compensate food shortage. The increment of GNP sharply cut down the cereal consumption. The consumption of fish, milk, eggs and meat reflected to increase since 1970.

  • This paper examines the historical relationship between the Little Ice Age and the Anthropocene, which has not yet been studied. The Little Ice Age is the coldest multi-century period in the Holocene. The reforestation of huge farmlands, abandoned due to pandemics in the Americas, aggravated the cooling weather of the Little Ice Age. It was in the long and severe cold of the Little Ice Age that the transition from renewable energy to non-renewable energy was completed in Britain in the latter part of the eighteenth century, and when the pattern of linear growth in greenhouse gas concentrations was forged in the ecosystems of the Earth. The Little Ice Age forced humans to depend on fossil fuels while the advent of warmer and more stable climate in the Holocene enabled them to start agriculture in an energy revolution 11,000 years ago, thus making the coming of the Anthropocene possible.

  • Future e-Trade RFID/USN distribution should satisfy the new needs of reasonable customers such as efficient supply of goods, presentation of information, and communication by developing intermediate and long-term strategies through analysis of industrial conditions and customers' needs. Through preferential application of new technology, knowledge-based e-Trade RFID/USN distribution environment and DB of industrial portal sites should be developed, RFID/USN infra such as Supply Chain Management(SCM) should be expanded, future-oriented knowledge-based services should be developed to prepare specific and realistic plans for proper UT(Ubiquitous Technology). Such change in e-Trade distribution environment should have historical and environmental backgrounds to suggest specific tasks and directions as a conversion of structural concept of engineering and trade theory for new u-Trade. Accordingly, this study is to present all the problems available in RFID/USN distribution, develop an organized and technological estimate model and provide a foundation to apply it efficiently. This study aims to present an interpretational foundation of RFID/USN distribution, rather than technical directions.

  • The purposes of the study were to detect and evaluate the historical land use and land cover changes on the Balan watersheds from three thematic mapper (TM) data, which were taken in 1985, 1993, and 1996. The supervised and unsupervised classification methods were adopted to classify five land cover categories: Paddy, upland, forest, residential, and water. The results indicated residential areas increased significantly during the past eleven years, Forest and paddy were converted to the urban areas. Future land cover patterns were forecasted using a Markov chain method, and the simulated land coiler change ratios presented.

  • This paper discusses the change of land ownership in the urban historical core of Kyungju city in the Period of Japanese occupancy(1910-45) based on the analysis of land register records. Kyungju city was not designated for the cities controlled by urban planning law which was set up in 1912 and 1934. The major purpose of this paper is to clarify the urbanization process of a Korean local city where the formal urban planning projects were not carried out. The focus of the study is the increase of the Japanese landowners and Japanization of the landscape. In the very beginning of occupation, Japanese already owned about 8% of the total land of the city centre where the old Kyungju castle had been located. The ratio of the land owned by Japanese went up to more or less 70% at the end of World war II. The process which the urban core had been replaced for the Japanese is very clearly traced from the analysis of a land register records.

  • Kyoto, which was Japan's political and cultural capital for more than a millennium before the dawn of the modern era, shows distinctive characteristics formed in the process of urban modernization. A citizen plaza perfectly fit to a modern city is lying on the east side, but a delayed urban reconstruction in the city center due to a strong conservative self-government awareness, as well as a delayed modernization of tax system, caused disorderly urban sprawl to appear in the suburbs. Thanks to the enactment of urban planning law enacted in 1919 by the government (Ministry of Internal Affairs) and an increasing awareness about the necessity and rationality of urban planning projects, urban renovation took place at a rapid pace. In the meantime, new ways of urban design were sought for and experimented to conserve it as a historical city against the city' quickly changing landscape.
