  • After the new house symptoms recently, room environment pollution problem of building syndrome and so on is becoming research about ways to solve this being risen. Is taking advantage of nature data by building materials by one of this way, but Friendly Environmental performance examination for structure material is insufficient misgovernment being real condition that put emphasis in ability as most embellishment and in finish. Environmental examination is insufficient misgovernment on factor itself as structure material. Also, being real condition that radon that is responsible for lung cancer occurrence next to smoke in building materials such as concrete and so on is happened, the danger is reported much through mass communications and research paper etc. Therefore, this research measured radon release amount and the carbon dioxide adsorption rate for physical special quality measuring and Friendly Environment Efficiency that follow to 'KS F 4004 Concrete bricks' regulation after manufacture Concrete Bricks utilizing charcoal that is nature material by sand. This study finding carbon dioxide density appeared and displayed effect that charcoal Controls radon release that happen in Concrete Bricks to maximum 74% that decrease to best 95% though decreased the charcoal addition rate increases.

  • The purpose of this study is to evaluate Suwon stream naturalness Index(S.N.I). and tofind out stats, problems and opportunities of the Suwon stream by assessment standard. Assessment standard is mainly based on physical structure of stream environment. the purpose evaluating sectors and elements are physical form and structure restoration of stream. To find out assessment standard of stream naturalness index, conceptual frame of assessment standard has been established, for which four sections, for example, longitudinal section, lateral section, stream bottom structure and water environment, have been selected. Overall stream naturalness index of the Suwon stream has been distributed at 3rd to 4th grade, and 3.3 of assessment index and mode were 3rd grade respectively. stream naturalness index of each section was as follows: Longitudinal section accounted for 3.7in average to be 4th grade, lateral section did 3.8 to be 4th grade, and water environment did 2.4 to be 2nd grade. Analysis of assessment outcome of stream naturalness index has checked status, problems and opportunities of corresponding stream. Assessment of stream naturalness index of the study provides useful information for restoration of close-to-nature stream, and furthermore has its meaning in checking problems and opportunities of Suwon stream.

  • 자연친화적 하천사업에 있어서 못은 하천환경을 구성하는데 기본단위이나 수환경상의 기능에 대한 평가는 이루어지지 않고 있는 실정이다. 못의 수환경을 평가하기 위하여 측정 자료를 토대로 한 일중 수질모형을 개발하여 적용하였다. 못의 하천환경에 대하여 물리적, 생태학적 관점에서 그 효과를 분석하였다. 못에 있어서 일중 수질은 혼합의 정도에 따라 영향을 크게 받으며 이러한 모의실험 결과는 향후 못의 조성에 따른 자료수집이나 일차 생산력을 이해하는데 유효하게 이용될 수 있을 것이다.

  • The purpose of this study is to overcome the realistic pressure and the limit of school environmental education and to develop an environmental education program that can provide students, who live in an urban area, have difficulty in contacting with nature, with an opportunity to experience the nature in the school outdoor environment, which is their daily living space and is a ground of environmental education. First, I developed an analytical tool which can be used to determine the degree how the environmental education is related to the school outdoor environment with 8 categories(spaces). And I analyzed the 2007-79 curriculum of lower grade(1 and 2 grades) of the elementary school provided by the Ministry of Education and Human Resources Development by using the analytical tool and found out that this curriculum was suitable for the environmental education utilizing the school outdoor environment. According to this curriculum analysis, the studying subjects which could be suitable for the environmental education utilizing the school outdoor environment were extracted, and based on these subjects, an environmental education program was developed. The environmental education 'in' environment program were composed with 5 modules and 18 activity subjects suitable for students advancement phase, and these activities can be implemented with experiencing, understanding and expressing by using 5 senses. I also proposed a plan that can be used to apply this program continuously to the lower grades(1 and 2 grades) original experience activity class.

  • This study is written with a purpose to foresee the changes of way of life in the 21st century trough recognizing an environment based on a correct ecological world-view and to create environmental design of seeing the nature and humans as one organism. This study is focused especially in environmental design and written generally based on urban ecology human ecology cultural ecology and plant ecology with this multi-interdisciplanary approach,. To understand meaning of ecosytem by considering the theory of ecology for ecological approach of the environmental design and to grope for possibility of applying environmental design by considering what to analyze and how to differenciate concept for ecological environmental plan from the mechanical design. Through this study it was realized that the ecological design starts from the recognistion of seeing the humans and nature as a one and form being aware of signficance of all the living things in our surrounding environment.

  • Conquering top and climbing was a major visiting purpose of Nogodan in the Chrisan National Park. The visitors prefered climbing as visiting times increased. 37 percents of the visitors did not know Mt. Chiri as a national park and 78 percents of the visitors did not understand Mt. Chiri as a observing nature area. No of visitors to Chirisan National Park and Nogodan increased each by 2.2 times (2.6 millions) and by 7 times (260 thousands), respectively after construction of the Sungsamjae access road in 1988.

  • This study is on landscape design of existing rural village focused on for improvement of community. It's so one of serious problems in landscape in almost rural area of the nation. For the finding clue of landscape design of village view through this study, we surveyed 1 village located in Sangju city. By surveying landscape design factor of village, we can propose design method and a few results as follow; Firstly, the structure of village landscape has five principle factors. The five factors of landscape are history and culture, housing and building, nature, agriculture, and environment design. Secondly, color existing of housings is to contain a primary color on roof which is not in harmony. Nevertheless, we can also find the reform measure and the possibility because of the knowledge of village people.

  • At present, Metal Oxide gas Sensors (MOXs) are widely used in gas detection because of its advantages, including high sensitivity and low cost. However, MOX presents well-known problems, including lack of selectivity and environment effect, which has motivated studies on different measurement strategies and signal-processing algorithms. In this paper, we present an artificial neural network (ANN) that models an MOX sensor (TGS822) used in a dynamic environment. This model takes into account dependence in relative humidity and in gas nature. Using MATLAB interface in the design phase and optimization, the proposed model is implemented as a component in an electronic simulator library and accurately expressed the nonlinear character of the response and that its dependence on temperature and relative humidity were higher than gas nature.
