The objective of the research is to analyze changing trend of water discharge in precipitation, according to changing land use, through an environment-friendly urban development method called LID. The study chose S1 basin (Separated Sewer districts) in Cheongju region for survey. Among LID methods, relatively more applicable methods of green rooftop space and parking lot with permeable material were selected to construct plausible scenarios. Curve Number (CN) value was calculated due to land use patterns in each scenario, and SWMM model simulation were conducted during 2008 for comparative analysis. For Case 1, only parking lot with permeable material was applied to the scenario. Green rooftop space I and II were applied to Case 2 and 3 respectively. For Case 4 and 5, green rooftop space I and II were applied, in addition to parking lot with permeable material, Calculation of CN value showed that for S1 basin, the value was 88.1 (prior to scenario application), 86.5 (Case 1), 81.9 (Case 2), 68.5 (Case 3), 80.4 (Case 4) and 67.2 (Case 5). Changing pattern of rain water discharge was analyzed for each scenario. For Case 1, the change was not remarkable before and after application of scenario. In Case 2 and 4, the impact of rain water discharge as source of pollutant fell to 20~30%. The rate dropped to 30~50% in Case 3 and 5 respectively. The result demonstrates that the amount of rain water discharge, amount and frequency of sewer overflow, frequency of rain water discharge, and pollution load decreased in accordance with declining CN value in each scenario. In installing green rooftop space, the effect was twice greater when rain water discharge was directly infiltrated into soil.

This report designs a landscape plan of six reservoirs in Sihung city which has possibilities both in development and in destruction. The report suggests how to create a leisure space in harmony with the surroundings in Sihung city. Building a leisure town will create the local residents' demand in recreational activities and improve the amenities. Therefore this study analyzes eco-friendliness of the land, conditions of fauna and flora, the quality of water and the usage figures of the six reservoirs so as to develop those six reservoirs more eco-friendly. Based on environmentalism, the leisure spot development plan attribute the ultimate importance to local residents' pleasant leisure time and recreations. With this master plan, the report suggests expanding the city's green space, since the city has under 50% out of the optimal percentage of green space per person. In addition, the report intends to plan each six reservoirs developed separately but organically connected at the same time that those six can put together and become a Sihung Green Way which makes the city's leisure space a belt. Apportioning the six reservoirs development levels in order to balance the development, accumulating and arranging buildings and facilities in available spaces according to the governing law, and creating resting area, promenade and parking lot to make an eco-city. Also the report suggests conserving environment and regulating contamination such as ban on fishing to move forward sustainable development. Since the adventives predominate the site, introducing indigenous plants should be necessary soon.

If human beings could make friends with nature, it would be a truly wellbeing. This project has selected the design concept under the supposition that human beings and the nature become friends. This residential house, which is consisted of one ground floor and two underground floors, is confronting the mountains that surround the residential complex. Residents can enjoy viewing the mountains from the living room. The garden is created by using this given environment in maximum. The walls are made up with rocks, and a small pond is formed with water from the mountain, presenting another attractive sight. Through the connection rather than the break between mountain and garden, living room and garden, and again garden and mountain, the dialogue with nature was attempted. The water of the pond in the garden flows down along the walls and creates another water space at the gate area of the house. Passing through the entrance, there are a living room, a kitchen, a bedroom for spouses, a common bathroom, and a library on the ground floor. On the second floor, there are two rooms, a bathroom, and a mini living room. The platform of living room on the 1st floor is lowered to produce the comfortable living room with the hearth. From the view of living room, the garden with full feeling of nature can give a good emotional rest for modem people who want the mental relaxation. The marble stones are used as its material to present rich texture and sophisticated image presentation. The hearth in the living room is harmonized with high-tech electronic home appliances and surrounding accessories. On the kitchen, the high-glossy materials are used to express the external appearance neatly and the depository function is more improved for housewives.

1960년대 이후, 우리나라의 산업화가 급격하게 진행되고 도시가 기능적으로 개발되면서, 도시내부의 강을 중심으로 하는 수변공간은 도로건설과 비선호성시설의 집적으로 도시민의 삶의 공간에서 소외되기 시작하였다. 특히, 산업화시대인 1970~80년대에 폐수와 쓰레기로 오염된 강은 생태 친수공간으로서의 역할을 상실하고 하수구의 기능으로 전락하였다. 그러나 21세기에 들어서서 지속가능한 도시에 대한 요구와 도시의 쾌적성에 대한 수요가 증가하면서, 도시민은 도시 내에서 맑은 물과 쾌적한 수변공간을 갈구하게 되었고, 최근에는 도시재생의 중심적인 공간으로 수변공간이 주목받고 있다. 본 연구에서는 도시 수변공간에 대한 이용현황과 계획의 문제점을 살펴보고, 도시 수변공간이 갖는 입지적 특성을 바탕으로 한 수변공간 활용방안을 분석하여, 우리나라의 도시적 여건에 부합되는 친환경적이며 도시재생에 기여하는 지속가능한 수변공간의 관리방안을 제시하고자 한다.

The water-gas shift reaction for the compact reformer was carried out at a gas hourly space velocity of 72,152 h^-1 over the Cu-Nb-CeO₂ catalysts prepared by co-precipitation method. In order to investigate the effect of Nb₂O₅ promotion over a Cu-CeO₂ catalyst, the Nb₂O₅ loading amount was systematically changed from 0 to 5 wt.%. Among the prepared catalysts, the Cu-Nb-CeO₂ (1%) catalyst showed the highest catalytic activity (CO conversion=61% at 400℃) as well as 100% CO₂ selectivity. The high activity and stability of Cu-Nb-CeO₂ (1%) catalyst are correlated to high Brunauer-Emmett-Teller surface area, small metallic Cu crystallite size, and enhanced redox property.

Excessive outflow of pollutant loads resulting from rapid industrialization has unbalanced the water ecosystem, deteriorating the water quality environment severely. Therefore, measures for improving the water quality are necessary to maintain clean reservoir water and restore water-friendly spaces. A water quality model which is capable of simulating daily reservoir water quality was developed. The model had been applied to Masan reservoir and Wanggung reservoir in Korea. The model appeared to be satisfactory in representing the trend of water quality variations by comparing measured and simulated results. The model had been also applied to assess water purification techniques such as dredged pool, floating island and vegetation purification system. The model was considered to assess the effect of water purification techniques on reservoir water quality improvement. The results of water quality simulation for lake water purification techniques showed that a large facility would be needed to meet the targeted water quality of the reservoir when only one technique is applied. To effectively improve the quality of the polluted reservoir water, it is therefore recommended that pollutant sources should first be controlled, and a combination of the water purification techniques applied to make the utmost use of their secondary effects such as conservation of the reservoir volume capacity, establishment of a recreation space, promotion of bio-diversity, and improvement of the lake landscape.

The purpose of this study is to provide basic data needed for planning and designing apartment community facilities in order to vitalize rental apartments. Outdoors community facilities of six rental apartments in Seoul were examined. The results are as follows. Firstly, the conditions of planning characteristics showed that the convenience is ranked as the highest priority of planning, compared to safety, friendliness and finally comfortableness. Community facilities are connected with the apartments and sidewalk providing convenient access for all apartment residents, there was little regard given to the features of comfortableness. Secondly, comfortableness of community facilities were shown to the lowest, compared to any characteristics. It is not easy to control noise and privacy in facility, and there are lack of near community facilities, for washing hands, drinking water and shielding from snow or rain, respectively. Thirdly, green facilities were shown to the highest applied friendliness more than other facilities. They were well outfitted with water space and gardening spaces, and robustly applied environment friendly materials and colors. Fourthly, resting facilities were shown to the lowest applied safety more than other facilities. Structure and material of facility are favorable but there is an absence of nonskid material and night-lightening system.
