    Correlation analysis was performed on the relationship of changes in air pollution in Yokkaichi City by taking into consideration the effects of various socioeconmic factors. The relationships of the incidence of new cases and mortality rate due to chronic bronchitis with the trend of air pollution were also evaluated. The consultation rate of middle-aged and aged individuals (40 years and above) for chronic bronchitis tended to decrease for the first time more than 20 years after the state of pollution began to improve in this region, but there has consistently been a significant correlation between the consultation rate and the degree of air pollution. Partial correlation coefficients of the consultation rate for chronic bronchitis with the degree of pollution, socioeconomic factors, and the rate of heavy smokers were calculated. As significant correlation was observed between the consultation rate and the family size. When the polluted area was compared with the nonpolluted (control) area, the consultation rate was consistently higher in the polluted area than in the reference area (residual effect), and the statistical significance of the difference continued, partly because of the refractoriness of chronic bronchitis once it is established. However, the incidence of new cases of chronic bronchitis in the age group 40 years and above decreased to the level of the reference area in about 4 years, closely reflecting alleviation of air pollution. Also, the mortality rate due to chronic bronchitis increased in all age groups with a decrease in pollution in the polluted area but decreased to the level of the control area with a delay of 4-5 years after the sulfur oxide concentration was reduced below the environmental standard. Recently, it has become comparable to that in the control area and has remained stable. Although the consultation rate of middle-aged to aged patients with chronic bronchitis in the polluted area tends to decrease, it has remained sightly higher than that in the control area due to residual effect. However, the incidence of new cases has already become similar to that in the control area, and the difference in the consulation rate is also expected to disappear in the near future.

    The purpose of this paper is to present the flow field with diffusion processes of air pollutant in a three dimensional numerical model. The previous model calculates a three dimensional wind field by using the mass consistent model that computes a total wind field from observed wind data on the ground at several observatory sites. Therefore, that model doesn't calculate the three dimensional momentum equations, and it approximates the wind velocities in each mesh point using the variational principle.Then, it causes the reduction of total computational CPU time in wind field computations. But, the previous model adopted the Cartesian Coordinates. so it has no good resolution of the topography for height data of the ground. In the present model of the Generalized Coordinates, the regular mesh system of the u, v and w flow field variables location is employed in order to cancel the truncation errors and to increase the resolution of the topography. This model strictly achieves numerical simulation of air flow, so we first determined the three-dimensional wind field of the entire Yokkaichi area from observatory wind velocity and direction data. Once the wind velocities in each computing mesh are obtained, next atmospheric diffusion and dispersion processes are computed by the convection diffusion equation. Using this method, we can trace the advection diffusion processes of diffused substances in the form of time development by the box model of finite-difference calculus. In this paper, the results of the real situation for sulphur dioxide diffusion processes from discharged smoke of petrochemical companies in Yokkaichi area in the past (in 1975) are shown. Computational results trend to agree well with real observed data in year averaged concentration analysis of sulphur dioxide.

    This paper describes one of the present activities of the Faculty of Environmental and Information Sciences. Since Cities of Yokkaichi and Tianjin are Sister Cities, our contribution to the sustainable development in Tianjin City is preferable. Based upon the result of Alkali-Soil reclamation at Shenyan City by adding gypsum, we are also to reclaim the alkali-soil at Tianjin. The soil improvement would result in economic growth through not only increasing crop production but also decreasing air pollutant such as SO_2. This paper shows additional possible projects that would enable sustainable development in the developing regions.

    In this paper, we investigate a quantitative evaluation of developmental projects involving petrochemical complexes and environmental policies for the reduction of atmospheric pollution in the Yokkaichi region. It is shown, using economentric model on the Yokkaichi region, that the calculation of environmental damage costs needs further consideration, and that the calculation of environmental damage costs needs estimating over the long term of a year. The calulation of environmental damage costs using direct measure underestimated the human damage within the scope of our knowing, therefore, we applied an indirect measure. Using the concept of imputed environmental costs in our analysis, the indirect impact measurement resulted in a higher cost estimate than the direct measure. Moreover, the imputed environmental costs rapidly decreased when an appropriate environmental policy was adopted. It is important in regional development policies that sufficient consideration be given and strict regulations applied to the environment and in addition, that efforts for environmental preservation begin at an early stage. Such policies will minimize damage to the environment, which will in turn minimize actual environmental costs for the improvement of the environment.

    The purpose of this paper is to study "crime of enterprises against the law of environmental pollution. In two classes of cases "crime relating to environmental pollution" has the meaning of a community. The result is that within the last few decades the Court has developed a much more flexible principle regarding service of process in personal actions, both those involving corporate defendants and those involving natural persons.

    At present, a wave of digitalization in broadcasting circles is in progress. The media environment rapidly changing with the opening of multichannel broadcasting via communication satellites, is breaking down the border between broadcasting and telecommunications, and expanding internet activities. At the same time, the broadcasting industry in Japan is being invaded by various industries including many from foreign countries. The free market tenet of capitalism is expanding more than before. Because of these circumstances, this paper argues for the necessity of a "Basic Broadcasting System" in order to secure an arena for public information dissemination, cultural programing, and unfettered journalism.

    We show a direct proof of the incompleteness of the quantum mechanical description in an interference experiment using a fast beam chopper. For further investigation, it is suggested that there may be a need to analyze the reduction of the wave packet experimentally as well as theoretically.

    "Mukza-Chip" was written by Sonching KYONG in 1688 in Korea, and "Warizan-Sho" was written by Shigeyoshi MORI in 1622 in Japan. The former is about a method of calculating with rods, which was influenced by "Suanxue Qimeng" (1299), a mathematical classic in China. The latter is about method of calculating with the abacus, influenced by "Sanfa-Tongzong" (1592) in China. While calculating with an abacus in Japan, it is necessary to recite the division table. The reciting voice was called "WARIGOE" (division voice). In Korea, while calculating with rods, it is necessary to think in peace and quiet, so there is not any voice. KYONG called this silence "MUKZA". KYONG and MORI were both deeply influenced by Chinese mathematics, but their attitudes to Chinese mathematics were very different. KYONG laid stress on traditional methods, and MORI sought new discoveries. KYONG handed on systematic methods and MORI adopted only practical ones.

    The purpose of this investigation was to determine the listening ability of students who took English Communication-Basic Course (herein-after referred to as 'ECB') by checking their self-evaluation of listening comprehension, and to clarify the level of teaching materials which were most suitable for use in ECB classes and their self-study hours at home. The investigation was made early in May, 1997,with 96 students who took the course (hereinafter referred to as 'the students'). The results of the investigation revealed that 93% of the students perceived the radio program 'Eikaiwa Nyumon' broadcasted by NHK in April, 1997,favorably for self-study use and that 80% of them had an impression that the TV program 'Eikaiwa' broadcasted by NHK in the same month was most suitable for use in ECB classes.

    This paper reports the results of a questionnaire study designed to explore the background, motivation and interests of first-year English students at Yokkaichi University. Primarily, this study was done in order to gather information to aid in the decision process related to choosing appropriate teaching methods and materials for this group of students. The results of the study indicate that although during the past decade there have been attempts to make high school English education more oriented towards communicative language use, considerable emphasis is still placed on helping students improve reading and grammar skills in high school English classes. The results also indicate that although students report that their previous experiences studying English have been somewhat unsatisfactory, they are motivated by the idea of studying English in university classes which have a greater emphasis on oral/aural aspects of communication.

    This paper is related to a larger work-in-progress with the current working title of Computers in the Learning, Teaching and Testing of English as a Foreign Language. In the last several years these fields have seen explosive growth, particularly as computers have become much more widely used in schools, in businesses and in the home. At the same time there has been a phenomenal growth in the use of the Internet-once the preserve of military planners, scientists and academics ; now open to any individual or institution connected to a network with Internet access. (See Matthew Gray 1996. Internet Growth Summary <http : //www.mit.edu.people/mkgray/net/printable/ internet-growth-summary. HTML> In this paper I hope to show the potential of the Internet in the Teaching of English as a Foreign Language, review some of the uses of the Internet in this field, with an attempt to estimate the benefits and drawbacks of these uses, and to suggest a course suitable for students who may be "Beginners" in both English and the Internet.
