The purpose of this study is to develop instruction model of environmental problem process focused with environmental justice. This study has analyzed environmental problem solution process in social studies of elementary school from 4th grade to 6th grade with it. The results of this study are as follows. First, social studies of elementary school didn't show distributive justice in environmental problem solving process. Second, procedural justice existed, but offered information is lacking to each main group. Third, substantive justice was emphasized personal viewpoint. We developed instruction model of environmental problem solving process based upon the results. Component of instruction model is problem analysis, distributive justice, procedural justice, substantive justice and evaluating a solution. Timely, teachers can use and can apply it in social studies class. In conclusion, it is strongly recommend to teach environmental education linked with environmental justice. It enables us enhance a new awareness and attitudes towards sustainable development.

The Water Environmental Education Program Using Streams(WEES) is developed to help the teachers increase their professionalism of incorporating a local environment into their inquiry teaching. The purpose of this study is inquiry about the 'Baig Cheon' stream with the perspective of environmental studies for WEES. Through these studies, we tried to get the background information in 'Baig Cheon' and profound insights into application of WEES. The 'Baig Cheon' was examined from the perspective of environmental studies through literature study, field study, and water quality monitoring. The results revealed the characteristics of the 'Baig Cheon' that ran across a rural area in terms of the watershed boundaries, water systems, and water usage. The changes to the water quality items were observed according to the spatial distribution at the measuring points across the watershed for six months from March to August, 2007. The results indicate that the water quality of the 'Baig Cheon' could well be affected not only by the natural and environmental conditions such as the geological features, but also by the human activities including the land uses in the surrounding roads, rice fields and farms and the water supply and usage. The inquiry of the 'Baig Cheon' from the perspective of environmental studies will hopefully make the education and inquiry process of WEES more meaningful and in-depth and contribute to providing better environmental education that properly reflects the nature of inquiry from the perspective of environmental studies.

The goal of the environmental education in High School is to make students survey and work out the issues on environment and to help them continue and improve the work. It is important that we should educate students the rational ability of decision-making. The more they can make decisions rationally, the more they participate actively in that. The purpose of this study is to develope the model of a new teaching-learning method coinciding with the goal of the environmental education of Social studies in High School. This study is backed up by the following developing processes. To begin with, the contents related to environmental problems in Social Studies Curriculum are being investigated. To urge the importance of STS(Science, Technology and Society), 1 will present the righteous understanding of Science in societal contexts, the development of rational decision-making abilities, and the cognitive connections between society and science. For this, 1'm representing a new model of learning-teaching method, backed up by Constructivism, especially Vygotsky's ZPD theory, giving 4 steps from everyday concepts to natural lingistic thought. Based on the above hypothesis, at last I will represent a STS whose topic is a problem of beach preservation because I intend to show the possibility of STS on the environmental education of Social Studies through this study. This study will help us lay a foundation stone of introducing STS in environmental education of Social Studies.

Background: Epidemiology is a fundamental study of public health, including environmental health, since the features and causes of diseases discovered through epidemiology provide crucial information for developing successful disease prevention strategies. Objectives: This paper tried to define the role and function of epidemiologic research in the field of environmental health, summarize examples of epidemiological studies with regard to selected environmental health events in South Korea, and address important issues that should be considered when conducting epidemiological research in the future. Methods: Epidemiological studies of selected environmental health events were reviewed and summarized in terms of their contribution to environmental health in South Korea. Based on the information, important issues were suggested for future epidemiological studies in environmental health. Results: The role and function of epidemiologic research in the field of environmental health includes the systematic description of the health effects caused by environmental exposure, verification of the causal relationship between environmental exposure and health effects, and provision of background data for conducting prevention strategies and developing policies. A number of epidemiological studies have contributed to characterizing and assessing the environmental risks involved in a series of environmental health events in South Korea. Conclusions: Important issues for future epidemiological studies may include health effects from chronic low-level environmental exposure, application of analytical epidemiology to elucidate causal relationships, use of exposure/disease/susceptibility biomarkers, accurate reconstruction of past exposure status, cohort recruitment and long-term follow-up, and in-advance surveillance of diseases with environmental causes.

Studies on the stem bark extracts of Garcinia cuneifolia have furnished a new xanthone cuneifolin (1) and the triterpene stigmasterol (2). Structures for these compounds were elucidated based on NMR, 2D NMR, MS and GCMS data. Larvicidal activity screening of the crude bark extract using the larvae of Aedes aegypti indicated the larvae to be susceptible to these extracts. $LC_{50}$ values of the bioassays show the extracts to be moderately toxic to the larvae of Aedes aegypti.

The 'Environmental Psychology and Behavior Studies' which started from the purpose of "Building the comfortable environment for people", is one of the most essential research area in architecture and intoner design field because of the basis of humanbeing matters. As the development of science and industries, the social circumstances have been more complicated and diversified. As a result, humanbeing require much humanized and high level of quality in space design as well as environmental design. In case of domestic research situation, the research of environmental psychology and behavior studies in architecture and interior design fields, haven't been applied fully in their potential abilities due to the shortage of research history, complexity of humanbeing researches and the vagueness of studies as a major fields. Thus, my purpose of studying is to analizing the previous research tendencies focus on the domestic thesis since 1980 to 2006 from the related research Institutes. Final findings are as follows ; 1. Steadily increasing tile interest ratio of the research field of environmental psychology and behavior studies 2. Concentration of research target spaces are higher from the residential > elderly facilities > educational > and medical spaces. 3. The preference of research theme showed the environmental psychology fundamentals > behavior studies > general studies of environmental psychology > emotional engineering > human factors engineering. 4. Results of crossing analysis ; 1)Residential spaces were the main spaces for main research theme. 2)Main theme used in target spaces were 'environmental psychology fundamentals' and "behavior studies'. 3)Main research methods for the most target spaces were 'sample research' methods.

Background: The occurrence of environmental disease is known to be associated with chronic exposure to toxic chemicals, including waterborne contaminants, air/indoor pollutants, asbestos, ingredients in humidifier disinfectants, etc. Objectives: In this study, we reviewed toxicological studies related to environmental disease as defined by the Environmental Health Act in Korea and toxic chemicals. We also suggested a direction for future toxicological research necessary for the prevention and management of environmental disease. Methods: Trends in previous studies related to environmental disease were investigated through PubMed and Web of Science. A detailed review was provided on toxicological studies related to the humidifier disinfectants. We identified adverse outcome pathways (AOPs) that can be linked to the induction of environmental diseases, and proposed a chemical screening system that uses AOP, chemical toxicity big data, and deep learning models to select chemicals that induce environmental disease. Results: Research on chemical toxicity is increasing every year, but there is a limitation to revealing a clear causal relationship between exposure to chemicals and the occurrence of environmental disease. It is necessary to develop various exposure- and effect-biomarkers related to disease occurrence and to conduct toxicokinetic studies. A novel chemical screening system that uses AOP and chemical toxicity big data could be useful for selecting chemicals that cause environmental diseases. Conclusions: From a toxicological point of view, developing AOP related to environmental diseases and a deep learning-based chemical screening system will contribute to the prevention of environmental diseases in advance.

VFAs like acetate are the major soluble metabolites of food waste leachates after digested. Therefore this study investigates the effect of acetate on growth rate and nutrient removal efficiency of Chlorella vulgaris to treat digested food waste leachates. The initial acetate concentration varied from 0 to 20 mM. As a result, Chlorella vulgaris growth rate was increased as high as the concentrations ranged from 0 to 20 mM. The same trend was observed with $NH_4$-N and $PO_4$-P consumption. The highest growth rate and the highest $NH_4$-N, $PO_4$-P removal rate were observed at acetate concentration of 20 mM. The microalgae growth rate and $NH_4$-N, $PO_4$-P removal rates were 1.5, 1.8, 2.3 times higher than the condition without acetate.
