Since 2000 country region developmental policy has been to integrate not only the improvement of physical living environment but also various subjects on ecology, environment, scenery, local culture, and green tourism. This study has recently established a decentralized Rainwater Management plan in order to provide an hydrology cycle system to the eco-village being planned by Seocheon-gun as a part of the garden village development business promoted by the ministry of agriculture and forestry. Hydraulic conductivity of the subject area is measured at $10^{-7}{\sim}10^{-10}m/sec$, and a flowerbed-type rainwater Infiltration system capable of controlling a non-point pollution source that stems from the development-caused impermeable surface has been applied. In the case of rainwater flowing out from the main entrance way and parking lot within the complex being treated in the flowerbed-type rainwater infiltration system, natural purification effects via soil and plants as well as natural water cycling effects through evaportranspiration and infiltration are expected. The significance of this study, compared to conventional decentralized rainwater management being applied limited to the urban areas, is that it offers appropriate rainwater management planning based on the analysis of the current situation of the subject area. Decentralized Rainwater Management is a valuable measure both economically and ecologically that reduces the burdens on local underground water cultivation as well as rain water pipe lines or purification systems, and sewage pipes.

Sinkholes happen in increasingly higher frequency in downtown areas with a concentration of social infrastructure these days. Most sinkholes occur around the living areas of citizens, which calls for a systematic countermeasure plan for urban development and underground water management, which are parts of the main causes of sinkholes. This study thus set out to analyze the risk factors of sinkholes in the subject area by using geospatial information deeply connected to sinkholes both directly and indirectly. The geospatial information used in analysis was obtained by examining the causes of sinkholes from a topographical perspective. Collected data were treated and analyzed with a range of spatial analysis tools based on GIS. The findings show that topographical factors had significant relations with sinkhole causes and raise a need to manage all kinds of pipe networks underground, the movement characteristics of underground water levels, and other topographical features. The findings may serve as data to support decision-making processes in the field of urban disaster prevention and call for extensive research to incorporate hydro-geomorphology and spatial modeling.

A street, as a linear factor constituting the city, is an axis of urban development. The substantial function of the street is the traffic space for the passage but now it plays the important role of the place of community where contains various activities such as meeting between people and people, rest, entertainment etc. A street is basically the 3 dimensional space consisted of the sidewalk, roadway and the roadside structures surrounding the street. In this case, the roadside structures are the physical composition factors for the street space and the facade of the roadside structures acts as important variables to form the image of street space. Thus, this study is to provide the basic data to be applied in the future urban street landscape plan by extracting the superior factors in visual and perceptional aspects which affect the image of street view from the shape composition factors which constitute the facade of the roadside structures, and by searching and analyzing the satisfaction degree and preference of each factors.

The most commonly used method for space management in the industry is development of site plans. These plans outline how to manage material deliveries, staging areas, and crane locations for construction sites in suburban area but not in congested urban areas. This study focuses on how to efficiently manage space for construction facilities on high-rise buildings in congested urban areas where normally space for facilities around a building footprint is not available. The limitations of available horizontal space create a need to explore vertical expansion of facilities. This raises new aspects of vertical facility handling and flow that need to be considered in the facility design problem. The construction facilities layout plan method provides layout planners with a valuable technique to develop efficient sequences of work that optimally defines how to efficiently utilize the construction facilities and minimize the travel of specific facilities effort on multiple-floor buildings. A genetic algorithm-based heuristic will be presented for generating block layouts for multiple-floor la)rout problems.

The consumption in the clothing's living has been diversified and rich by the increase in pay, the ostentatious propensity to consume and the diversification of distribution on structure in accordance with the advance of clothing industries, etc. The clothing, however, was not used properly due to the thoughtless purchase, the sudden change of fashion and the difficulty in the use and management of clothing. Most rural communities, furthermore, have the poor market, and the unreasonable management could be often observed, e.g., some people don't follow the care label or burn the clothing to waste. This study was conducted to provide the tool measuring the standardized clothing management behaviors so that the systematic and effective instruction could be achieved to improve the living standards 623 rural and urban housewives to develop the tool measuring the standardized clothing management to compare and measure the effect of before and after the education and guide all the way. And then, we developed the standardized measurement tool consisting of 6 parts of 60 questions after analyzing the validation and reliability of the questions. As a result of analyzing the validation and reliability of the developed tool, each Conbach alpha value of clothing living showed the good reliability; the value of the purchase plan was 0.76, the purchase was 0.83, the wear was 0.80, the management was 0.84, the storage was 0.83, and the disposal was 0.74, which indicated that it was able to use as a standardized tool.

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.
