본 연구는 도시화 과정에서 발생한 도시 열섬현상을 완화하기 위해 도시 내에서 시행할 수 있는 생활권 녹지 조성 방법인 근린공원 조성, 소공원 조성, 주차장 녹화, 가로수 식재, 옥상·벽면 녹화 다섯 가지의 유형에 대해 세부 녹화 시나리오를 설정하여 열환경 개선 효과를 정량적으로 분석하는 것을 목표로 한다. 열환경 개선 효과를 확인하기 위해 미기후 시뮬레이션 프로그램인 ENVI-met 4.4.6v 모델을 활용하였다. 분석 결과, 공원의 식재 밀도가 높아질수록 기온이 낮아졌으나 사람이 느끼는 온열 체감 정도인 열쾌적성 지수 PET는 기온과 정비례하지 않았다. 수목이 증가하며 기온은 감소하였으나 상대습도가 소폭 증가 및 풍속이 다소 감소하였으며, 특히 PET에 많은 영향을 미치는 평균 복사온도가 수목 밀도와 정비례하지 않아 PET 역시 기온과 다른 양상을 보였다. 소공원은 한 개소 조성 후 효과를 확인하였을 때 최대 56m 반경까지 기온 저감 영향을 주었고, 250m 간격으로 세 개소를 추가 조성한 경우 기온 저감 범위가 약 12.5% 증가하였다. 기온과 달리 PET는 식재된 수목 영역 인근만 영향을 미쳐 소공원 조성 후 주변 환경의 열쾌적성은 큰 차이를 보이지 않았다. 지표면 포장을 아스팔트에서 잔디블록으로 변경하거나 옥상 및 벽면녹화 시행 등은 직접적인 일사 차양의 역할을 하지 않으나 기온 저감에 긍정적인 효과를 주었고, PET는 세 유형 모두 조성 전후 유의미한 차이를 보이지 않았다. 가로수는 식재 간격이 좁을수록 더 높은 기온 저감 효과를 보였으나, PET는 수목 밀도와 정비례하지 않았다. 가로수 하부 관목 식재의 경우 기온 저감에는 큰 영향을 주지 않으나 열쾌적성 개선에는 긍정적인 영향을 주었다. 본 연구는 도시 열섬현상 해소를 위한 생활권 녹지 조성 전략을 개괄적으로 제시하고 효율적인 열환경 개선을 위한 세부 전략을 수립하는 데에 활용될 수 있을 것으로 판단된다.

The fire area need management to prevent enlargement of collapes and sinkage. and it need that repair Vegetation sack work, Soil arresting structure, Terrace-sodding works, Direct seeding works in greening works and Water cushion in erosion control dam. The whole of the Concrete stream grade stabilization structures were broken, it need to be repair. As pass the time, a lot of structures were abandoned. Therefore, it need to reorganize erosion control structures and the method of construction in the fire area

This paper aims to analyze ecological characteristics of interior design, selecting as the subjects Busan-based construction companies which have a model house, among those that distribute apartments in Busan as of August 2006. Primarily, literature research Is conducted to understand recent trends of interior design for apartment building, present situations and characteristics of ecological design, and prepare environmentally-friendly guidelines and check-list items on the basis of domestic and overseas cases. Collected data in turn is analyzed to assess ecological characteristics of apartment building design in Korea today and present problems and directions for the future.

This plan is for a different type of welfare facilities devised by analyzing problems with existing welfare centers and focusing on connection with residents and link between culture and welfare and among generations. In terms of re-development plan of Youngsun-2-dong, Youngdo-gu, Busan and the neighborhood under this plan, Youngsun-dong, Youngdo-gu is one of the densely populated districts of the aged, with lower growth rate and poor housing and welfare facilities. However, the district has a blessed natural environment and historical site of cultural relics of the Neolithic Age as well as growth potential as a logistics center with broader network of roads linking with Bukhang Bridge when Namhang Bridge construction is complete, showing the aspiration for change toward hi-tech maritime city in the 21st century of Youngdo-gu. This plan is expected to promote unity between the old and children, protection from social marginalization, and re-socialization education and set the stage for participation and solidarity of residents in the community.

Recently, because a renewable power source must operate as a constant rate in accordance with RPS(Renewable Portfolio Standard), the study of the renewable power sources has been ongoing. Especially because of noise of wind turbine, troubleshooting, and urban greening business, research related with small wind turbine are underway. The economics and reliability are important parts for the activation of small wind turbine, such as solar energy. In this paper, by analyzing the temperature variations for each location and efficiency of power conversion devices in accordance with short period wind speed changes in simulation test, we reviewed the safety about temperature variations of wind generator and the method of selection of power converter.

With the rapid development of China's industrialization and urbanization, air pollution has become a growing concern. The emergence of air pollution not only affects people's health, but also restricts the development of China's social economy. This paper puts forward specific measures for air pollution control by examining the causes of air pollution and by comparing air pollution status and management policies between Korea and China. Methods of control involve improving the urban environmental management mechanism, spreading awareness of urban environmental management and air pollution management laws and regulations system, strengthening clean energy utilization and urban environmental greening, increasing investment and management funds and more. Through these measures, urban environmental management in China can be accelerated and level of environmental management improved.

Recently, as part of an effort to realize the low-carbon green growth, the research to measure the degree of greening about the road facility with United States as its center was performed. In addition, the Green-road certification is enforced and applied. In this study, we would like to examine the applicability of the green-road certification to domestic road to promote the settlement of green-road certification system to contribute the related industry development for the green technology development and application and spread in the roads sector.

Recently, in addition to greening of roof and artificial soil, Rootproofing to prevent damage to the waterproof layer and structures by roots is recognized as an important task. Therefore, various related products and construction methods have been developed and applied in the field. However, in the case of synthetic polymer-based sheets most commonly used in domestic construction sites, Most are produced using 100% new materials that are not suitable for green trends such as resource conservation and environmental protection. Therefore, in this study, we developed TPO sheet using recycled material, which is a technology that can secure eco-friendliness by utilizing recycled resources. As a result of the evaluation of tensile performance of the TPO sheet according to the recycled material content, The tensile strength of the specimens with the recycled content of 50 ~ 70% was the highest, The elongation rate of the specimen with the recycled content of 30 ~ 40% was the best.

The subject is to find green roofs' location as stepping stones in green-network in fine scale. The study site is Junggu, Seoul, which has core areas(Bukaksan and Namsan) and green areas(parks, etc.). Through literature review, the closer to core areas and green areas, target species reach green roof easier, and target species must be avifauna(flying species) and high class in food chain, because of possibility of reaching. So, Great Tits, inhabited in Namsan and urban bird, is target species. The location standard of green roofs, realized birds' reaching distance, consists of home range(horizontal range and vertical range) and roof-greening capable area. The green roofs' distribution of location was resulted through GIS analysis of feasible site finding, and classified with weight of score. In discussion, Namsan gives more effect to locate green roofs than Bukaksan does and selected buildings which are grouped in some parts need to be managed with group, green roof district.

This study aimed at framing alternative urban planning scenarios reflecting urban planning factors, performing urban climate simulation and evaluating eco-friend and low energy characteristics of each scenario on the viewpoint of urban temperature and energy savings on the target of the costal city including Haeundae District in Busan The results are as follows. 1)The fact that urban higher temperature is approximately 2.5 times higher in the building constructed area than whole urban area was represented severe higher temperature phenomenon in the built-up area. Ground greening, water scenario and soil scenario could be expected peek air temperature alleviating effect in order. Especially water scenario had significant effect(maximum $2.5^{\circ}C$) on lowering of air temperature.
