This study aims to clarify the impact of environmental issues on sustainable environmental management performance through the establishment of internal and external networks and environmental management activities. As a result of analyzing 163 final collected data of companies, social environmental issues did not have a significant effect on the internal sharing system, but they had a significant positive effect on both regulatory response and cooperation network establishment. In addition, the regulatory response to the environment has a significant effect on both the internal sharing system, cooperation network establishment, and environmental management activities. Lastly, environmental management activities have a significant impact on sustainable environmental management performance, indicating that environmental issues are leading to environmental management activities and performance by promoting sustainable growth of companies.

Values and attitude towards the environment begin to form in elementary school. Thus, environmental education is effective to promote children's sensibility on the environment, to increase their interest and concern on it, and to make them have friendly attitudes towards it. As a measure of such education, experiential learning activities are being emphasized, where children can see, feel and experience for themselves in a familiar environment surrounding them. Based on the results of this research, the following proposals can be made for environmental education necessary for elementary school children. i) the contents of environmental education should be selected and organized according to grades. Also, schedule should be secured to provide environmental education in certain time. ii) program should be developed to fit into local characteristics and academic level, providing connective and consistent environmental education. iii) activities for environmental education in elementary school can be effective only if connective guidances are provided among school, home and local community. iv) the recycling and separate collection activity program used in this research was limited to 3rd graders in small-size rural schools. Additional research may be necessary to see how long their attitudes last according to different grades.

Superoxide dismutase (SOD) activities were investigated from the portions of shoots and roots in accordance with developmental stage and in response to environmental stress and antioxidants using Rhodiola-seedlings. The rates of SOD activities were revealed highly at the portion of roots and its tip of seedlings in the latter stages rather than the initial stages. SOD activities of seedlings in the initial stages treated with sodium chloride and cadmium as environmental stressors showed the decrease by 15 and 30% with respect to the control, respectively. However, in spite of stressor-treatments, the activities in the roots were increased according to the growth period showing a maximum rate of up to 45%. Also, SOD activities of the seedling treated with ascorbic acid as a antioxidant were increased by 46% of control value, but this was similar to the rate revealed in the presence of stressors. These results suggest that SOD activities in Rhodiola-seedlings may be related with the important defence-system against injurious environments.

Strobilurins are one of the most important classes of agricultural fungicides. To discover new strobilurin derivatives with high activity against resistant pathogens, a series of novel ${\beta}$-methoxyacrylate analogues were designed and synthesized by integrating substituted pyrimidine with a strobilurin pharmacophore. The compounds were confirmed and characterized by infrared, $^1H$ nuclear magnetic resonance, elemental analysis and mass spectroscopy. The bioassays indicated that most of the compounds (1a-1h) exhibited potent antifungal activities against Colletotrichum orbiculare, Botrytis cinerea Pers and Phytophthora capsici Leonian at the concentration of 50 ${\mu}g/mL$. Exhilaratingly, compound 1d (R=3-trifluoromethylphenyl) showed better antifungal activity against all the tested fungi than the commercial strobilurin fungicide azoxystrobin.

This study was intended to develop the STS module regarding conservation of water resources, called "A Project for the Conservation of Water Resources". Since each theme consisted of 2 subject activities, they had total 8 subject activities. Developed STS module was applied to 113 male students of 11th grader of D High School in Incheon. After they received 8 periods of the developed STS module, the environmental sensitivity and environmental conservation behavior and the interest of the affective domains related to science were determined. Results were as follows; Four themes of this module were 'What are the water resources?', 'What is a main cause for the water pollution?', 'A drinking water? or non-drinking water?' and 'Making UCC for the water resources'. Since each theme consisted of 2 subject activities, they were for total 8 periods. Developed STS module was found to be appropriate for the STS and they could be applied to the classroom easily. Students who were instructed according to the developed STS module showed that there was a statistically significant enhancement in the environmental sensitivity and environmental conservation behavior and in the area of interest of the affective domains related to science. Students who were instructed according to the developed STS module showed positive responses to the instructional methods by STS. Based on students' interview, they revealed that they were impressed with the hands-on activities and the process of subject activities. Instruction with STS module seemed to be more appropriate way of teaching compared to the traditional way of teaching. However, it will be necessary to develop more modules or programs which could be linked from the elementary school level to the high school level and to use them consistently in order to maximize their effects.

The purpose of this study is to analyze environment-friendly consumption behaviors and consumption value of adolescent consumers, and to analyze the effects of environmental knowledge, environment and experience, perception of environment, the awareness of consumption and environmental pollution, and consumption value on environment-friendly consumption behaviors of them. The data were collected by 999 adolescent consumers in Jeju Province. Data were analyzed by frequency, percentage, t-test, one-way ANOVA and Scheffe’s multiple range test using SPSS 12.0 Program . The results are as follows. Economy had the most cause and effect influence on environment-friendly purchasing behaviors, followed by experience of environmental activities, eco-friendliness, esthetic sense, enjoyment, and awareness of consumption and environmental pollution. Regarding the environmentfriendly consumer behavior, economy is the most influential factor, followed by eco-friendliness, awareness of consumption and environmental pollution, experience of environmental activities, environmental knowledge and monthly average allowance. Eco-friendliness had the most cause and effect influence on environment-friendly disposal behavior, followed by awareness of consumption and environmental pollution, economy and experience of environmental activities.

The purpose of this study is to survey and analyze the environmental awareness and attitude of elementary school students, adapting the CHEAKS(Children's Environmental Attitude and Knowledge Scale) for Korean elementary students, which is the valid-tested tools for children's environmental awareness and altitude. The subjects are 580 students from 6 elementary schools. The differences of the environmental attitude are surveyed and analyzed by environmental education activities, such as environmental activities in school and “the school forest movement”, and environmental awareness and concern. The results are as followings: First, the subjects replied that the environmental problems are very serious, such as atmospheric pollution(37.6%), water pollution(22.2%) and food waste(16.3%), but they are relatively optimistic of the future environment. Second, the verbal commitment subdomain and the affect domain are evaluated higher than the actual commitment subdomain, and the environmental issues of water, energy and recycling are considered more importantly than other issues such as environmental generals, pollutions and animals. Third, the grade and the sex have little effect on the environmental attitude, but the environmental education activities have great positive effect, such as the experience of environmental camping, the education of saving resources, waste separation and the experience of raising plants and flowers. Fourth, the students with high awareness and concern about the environmental problems have high environmental attitude. Especially, the awareness and concern on the flowers and plants have very strong correlation with environmental attitude, regardless of the subdomains. Finally, the students from the school participating “the school forest movement” have relatively positive environmental attitude. Particularly, the participation of students and the positive approach of the school have positively great influence on the students' environmental attitude in all of 3 subdomains and 6 environmental issues.

The purpose of this study is to investigate the present status of environmental education administration in the middle schools of Seoul City and to find problems to be solved environmental education in middle schools. To accomplish these purpose surveys for middle school teachers in Seoul was conducted, and evaluation reports of school environmental education of 1998 were analyzed. The results indicated that both schools and Ministry of Education offered few evaluation standards related to environmental education. Most schools abolished division of environmental affairs because of the reorganization of school system, which focuses on subject and aptitude-based education. In addition, environmental education and related activities were maily the responsibilities of division of science education. The teachers responded that such activities as organization and management of mothers'social service, management of environment day, use of environmental conservation card, and establishment of conservation area were not effective and should be abolished. The conclusion from this study are that environmental education can be effective only when goals of environmental education are included in school evaluation, and the division of environmental affairs should be revived and systematically operated in school.

Spatial variations of physicochemical and microbiological variables were examined to understand spatial heterogeneity of those variables in intertidal flat. Variograms were constructed for understanding spatial autocorrelations of variables by a geostatistical analysis and spatial correlations between two variables were evaluated by applications of a Cross-Mantel test with a Monte Carlo procedure (with 999 permutations). Water content, organic matter content, pH, nitrate, sulfate, chloride, dissolved organic carbon (DOC), four extracellular enzyme activities (${\beta}-glucosidase$, N-acetyl-glucosaminidase, phosphatase, arylsulfatase), and bacterial diversity in soil were measured along a transect perpendicular to shore line. Most variables showed strong spatial autocorrelation or no spatial structure except for DOC. It was suggested that complex interactions between physicochemical and microbiological properties in sediment might controls DOC. Intertidal flat sediment appeared to be spatially heterogeneous. Bacterial diversity was found to be spatially correlated with enzyme activities. Chloride and sulfate were spatially correlated with microbial properties indicating that salinity in coastal environment would influence spatial distributions of decomposition capacities mediated by microorganisms. Overall, it was suggested that considerations on the spatial distributions of physicochemical and microbiological properties in intertidal flat sediment should be included when sampling scheme is designed for decomposition processes in intertidal flat sediment.
