The correct river discharge is a important item to keep a river role of using, controlling and ecology. Especially river role of ecology is very important for environmental development of river. In assesment of ecological flow, exact information of river life and topograph is very important. In this paper, the assesment of environmental flow is conducted using geo-spatial data of basin and river. The geo-spatial data is used as a important basic data in river restoration.

This study intends to develop a GIS-based environmental assesment technique for environmental friendly road route plan using a spatial analysis function. After embodying an impact range based on the analysis of factors which cause the environmental damage by the road construction, a literature survey on a diverse grading cases and legal regulations was conducted. As a quantitative model for the spatial analysis, AHP was selected. As the environmental assessment, 8 items such as topography & geology, animals & plants, soil ecology, water quality, air quality, noise, land use, and landscape were selected. and then finally classified into three-grades using a pairwise comparison of the alate collected by a questionnaire surveying, weighting values were applied to there 8 items. The highest weight value, the grade 1 among eight was 0.191 for animals & plants. As the result of verifying the above method for the case region, the most environment-friendly road route could be generated.

o US environmental regulations are complex o Compliance assesment should be part of an effective environmental management system o Companies must assess and report a dollar value for environmental liabilities o Comprehensive assessment of environmental liability and risk should be conducted for all property transfers aquisitions o Independent external audits provide the highest level of compliance oversight and can assist in assessment of environmental liabilities

There has been a steady increase in geoenvironmental engineering projects where geotechnical engineering has been combined with environmental concerns. Many of these projects involve some investigation on contaminant and leachate flume in the ground and landfill. In this study, investigation and assesment on soil and groundwater around the waste landfill was carried out. Many techniques such as drilling and sampling method were applied. As a result of this study, the concentration of soil and groundwater were investigated and analysed.

This study is aimed at compare and evaluate the environmental impact of End-of-Life Vehicle(ELV) on the eco-friendly technology dismantling and recycling system, using Life Cycle Assessment (LCA) method. In this study, it was analyzed for the environmental impacts of raw materials, disassemble process, recycle parts separation and waste treatment into the process of ELV treatment by greenhouse gas and resource consumption, etc. Through this study, the indoor rail type dismantling technology were recycling rate applied on the alternate system was increased by approximately 8%. As a result, it was 3 to 88% by improving the environmental impact category. In addition, the added benefit of approximately 8 - 62% in pre-market occurred through the recycling rate, improve parts reuse rate of ELV. Through the results of this study, legal compliance, improved reuse and recycling ratio, used parts market reach, enable exports has identified the need for the effort that the dissemination and diffusion of eco-friendly technology.

The study is conducted to analyze the questioning styles in three middle school environmental textbooks in terms of frequency, type, and placement of questions. It is also to analyse and compare the kinds of scientific processes elicited by the questions in the topics of textbook. The instrument was the Textbook Questioning Strategies Assesment Instrument (TQSAI) which was developed the Cooperative Teacher Preparation Program, University of California. The mean number of questions per topic was 4.0 and the ratio of questions to sentences was 3.8%. The numbers of empirical and non-empirical questions were 52.5% and 47.5% for textbook D, 56.6% and 43.4% for textbook J, and 92.7% and 7.3% for textbook K, respectively. The open-hearted question was the highest in all types of questions for three middle school environmental textbooks. The explanatory question was the highest in all characteristics of questions. The types of various questions were distributed throughout textbooks including the green field, debate-discussion, examination, and so on.

University campuses, in Korea, experienced expansion during the 1970's and exceeded its capacity in the 1980's. On the other hand, universities needed to deal with increasing capacity and expansion of its facilities. This study is carried out in three steps : developing the factors of environmental friendly assessment, designing an assessment table based on specific categories, and applying the categories to the campus of Seoul National University. The assessment factors and assessment table were designed through a survey of experts in landscaping, architecture, and urban planning. The elements of major categories were classified as follows; 1) Management of land and accessibility, 2) Pollution and waste matter, 3) Energy, 4) Natural resources, 5) Operation, maintenance and management of environmental friendly campus. And, this study classified five major categories into twenty subcategories on the evaluation of the environmental friendly campus. The twenty subcategories include various fields such as architecture, landscape architecture, environment, urban design, and social sciences etc., profound studies at this line should make more precise assesment guidelines.
