This study examines how Japanese firms' decisions about the overseas production activities are influenced by economic and socio-economic characteristics of host country . The focus has particularly set on the impact of the chemical control notification laws, which may deter the direct investment. The empirical analysis utilizing the logit model has been conducted on the foreign direct investment decision made by Japanese firms which engaged in chemical production during the 1980 s. In addition to using aggregated data from the Ministry of Finance, the study takes special care to use information on individual firms by using data from Toyokeizaishinpousya. The use of such disaggregated firm level data is the distinguishing feature of this study. The results indicate that implementing the chemical control notification laws has a negative impact on the inflow of the foreign direct investment. The results also show that these factors such as the decrease in labor cost, the market size, the country credit, and the agglomeration of the industry attract foreign direct investment.

It is getting necessary for the government to communicate with citizens in order to implement a public project which leads to serious destruction of the environment. We call this Environmental Communication. In Environmental Communication, the planner must give information to citizens' for clearing their misunderstandings of the project that distort their valuation. The purpose of this paper is to develop the model that specifies these misunderstandings in Awase reclamation project in Okinawa. There are 2 alternatives of such model. One is the model in which citizens' recognition of the project directly influences their valuation. The other is the model in which their recognition influences their expected results of the project and then these affect their valuation of the project. By using questionnaire data and applying bootstrap GMM-J test, extension of bootstrap -J test, we selected the former model. And this model could specify misunderstandings that distort the valuation of the project.

This paper developed a computer software for zero-emission simulation to optimize the waste disposal process in local community. A user sets waste disposal plants and waste discharge distribution on a map for the simulator to calculate a cost of waste disposal. The cost of waste disposal is defined as the product of distance and amount of waste. The waste discharge distribution is estimated by statistical data . To achieve accurate simulation, actual road maps are used to estimation of distance between disposal plants and waste sources. By calculating the total cost with various parameters, optimization of the cost of waste disposal is achieved . In this paper, the functions and the usage of this zero-emission simulator are reported.

In recent years study of "Kankyougaku"has become popular in Japan. However, the research is being continued in the situation where characteristic of "Kankyougaku" has not been clearly in academic aspect. From this reason I have decided to clarify academic nature of "Kankyougaku" by analyzing [Purpose] [Object of Study] [Method of Study] [Others] taking up books and papers dealing with Synthetic and One system Science, Study and Research on environment and environmental problems. As a result, it has become clear that "Kankyougaku" in Japan can be describe as follows;1. Purpose: To present theory to realize better environment.2. Object of Study: Human Beings and Environment (inclusive of interrelation).3. Method of Research: To analyze, connect, unify and evaluate factors of environment and environmental problems.4. Others: Characteristic of others are [Reevaluation of Factor Revivification], [Systematiza tion of Study, Method and Knowledge for environment], [Fusion of human and cultural, social and natural science] and [Open the way for Interdisciplinary study by individual].

Effects of a high magnetic field gradient (8T, ca. 400 T²m^-1) on the behavior of E. coli were examined. The speeds for movement from a high (8T) to a low field (1.5T) and for the opposite movement are 1.35 and 0.49 cm h^-1, respectively; it is 0.65 cm h^-1 in a zero field. The magnetic force hastens the downfield movement of diamagnetic E. coli and impedes the up-field movement.
