The purpose of this study is to analyze user's behaviors and environmental image to show how to plan dining facilities by checking what factors make user's satisfaction and how inferior factors effect dining people. The spaces in this study are dining facilities in a University. Dining places are campus welfare facilities, students don't have other choice. Dining facilities are determined according to user's desire to convenience and time saying. And this facilities will be compliment to resting places in campus. As we know, functional planing facilities are central element in University Master Plan and must consider interior decoration, surrounding places and some other instruments. Scale of dining facilities must accommodate with many students, therefore dining facilities can served as spare place and resting space.

The Ministry of Health and Welfare of Japan has set up six research groups concerning the endocrine disrupting chemicals. One of these projects was "A study on development of testing methodology for health effects due to exposure of environmental endocrine disruptors". In this paper, three topics are described. In OECD collaboration for pre-validation of uterotrophic assay, the most sensitive response to ethnyl estradiol was noted in the ovarectomized rats treated subcutaneously for 7 days. Secondly, it was suggested that changes of the serum $\alpha_{2u}$-globulin level may be a sensitive parameter for detecting the estrogenic activities of chemicals. Finally, development of the sexually dimorphic nucleus of preoptic area in the brain oj male rats was inhibited by the treatment with estrogenic chemicals, and their masculine behaviors and reproductive abilities were impaired after sexual maturation. In conclusion, these parameters are considered to be sensitive endpoints for testing estrogenic chemicals.chemicals.

The United Nations Framework Convention on Climate Change (UNFCCC) is an international environmental treaty to stabilize greenhouse gas concentrations in the atmosphere. In order to fulfil the commitments of the countries in an economically efficient way, the UNFCCC adapted the emission trading scheme in the Kyoto Protocol. If the UNFCCC's scheme is enforced in the country, considerable changes in electric power industry are expected due to the imposed greenhouse gas emission reduction. This paper proposes a game theoretic model of the case when generation companies participate in both competitive electricity market and emission market simultaneously. The model is designed such that generation companies select strategically between power quantity and greenhouse gas reduction to maximize their profits in both markets. Demand function and Environmental Welfare of emission trading market is proposed in this model. From the simulation results using the proposed model the impact of the emission trading on generation companies seems very severe in case that the emission prices are significantly high.

After the introduction of Volume-based Waste Fee System for municipal wastes, the disposal of food wastes became an issue an issue in society. Concerted efforts among government agencies have been made to manage food wastes separately from municipal wastes. For example, the Ministry of Environment, the Ministry of Agriculture and Forestry, and the Ministry of Health and Welfare established the '5-year('98-'02) Basic Plan for Recycling Food Wastes' in September 1998. Also changes in the waste disposal system has been sought, aiming at the Resource-circulating Society.

In recent years Korea fisheries have been much more influenced than ever before by domestic and foreign environmental changes such as market liberalization, sustainability, efficiency and effectiveness of domestic fisheries, fisher's welfare etc. Under the wide range of environmental changes, government is carrying out various fisheries policies. However, it seems insufficient to accomplish policy goals under the existing policy instruments. The main focus of the paper is to investigate structural changes and policy directions of fisheries finance in Korea after asian economic crisis. The results of the study are as follows; Fisheries sector in whole economy has been lowering in its proportion. To survive in emerging global competition, fisheries sector is needed structural reformation. In particular the strategy that increases operative efficiency and effectiveness on government financial policy in fisheries sector is much expected. Also, it is necessary to minimize costs, to reform institution and management for increasing efficiency and effectiveness.

Minamata disease made its first appearance in the world at Minamata City, Kumamoto Prefecture, in May 1956. In 1962 methyl mercury poisoning through the placenta was found for the first time in the world. This was called congenital Minamata disease. In all cases the clinical symptoms were consistent with those of cerebral palsy. The time and place of outbreak were the same as those for Minamata disease. Their mothers had eaten fish and shellfish during pregnancy. The principal symptoms of congenital Minamata disease are mentalretardation ($100\%$); primitive reflexes ($100\%$); disturbance of coordination ($100\%$); dysarthria ($100\%$); limb deformation (100%); growth disorders ($100\%$); nutritional disorders ($100\%$); chorea-athetose ($95\%$); and hypersalivation ($95\%$). However, today, when the world is polluted by mercury in various places and at various levels, the data we need is not represented by those severe cases, but rather by the chronic milder type. Even in Minamata, the issue of Minamata disease has not been resolved. And likewise, on a global scale the problem of Minamata disease is not yet over.

The OECD acute toxicity guideline has been revised recently to protect animal welfare. The GLP authority of the Ministry of Environment, the National Institute for Environmental Research, recommended GLP laboratories in Korea to ufo the revised acute toxicity guideline. This study was carried out to optimize newly adopted OECD test guideline 420 (TG 420). Bisphenol A was selected for test chemical. Following TG420, Bisphenol A was classified as class 5/unclassified group. The revised TG 420 was very effective test in minimizing animal number and classifying chemicals. The method, however had short-coming in evaluation of test results statistically because the test had no control group, and the test should be stopped when animals were dead at the lowest dose or alive at the highest dose. TG 420 required at Least 20 animals to complete the test, but it could result in producing unused animals that need to sacrifice.
