The purpose of this research is to provide basic data for the promotion strategy to activate modular construction system as residential facilities, through a study on the architectural planning, institutions and policies and research on connection details, for the use as residential facilities of the modular construction that is not actively supplied for the general residential facilities. As a result, I suggest sample model plan of domestic and foreign case analysis and characteristic of modular construction and practical application of modular construction for Residential Facilities. Owing to many advantages including short construction period structural stability and economic benefits, modular construction is expected to play a role as residential alternative of socially controversial affordable housing and weekend homes, and potential housing shortage after reunification; and to contribute to the development of design automation and industrialized constructions. Though Korea is still lacking development of the system that meets the domestic context, if supported by ongoing researches on the development of construction methods, materials and details, the settlement of appropriate modular residential facilities to suit the national situation will serve a possible alternative solution for many housing and environmental problems.

이 연구는 채석장의 실태조사를 통하여 토석채취 후 합리적이고도 완벽한 복구를 실시하기 위한 기초 자료를 제공하기 위하여 전국의 18개 토석채취장을 대상으로 조사한 결과는 다음과 같다. 농어촌정비사업에 따른 토석 채취 후 산지복구지는 대부분 조경적 녹화가 이루어지고 있다. 또한 복구공사 후 유지관리가 이루어지지 않아 식재한 나무가 고사하거나 비탈면녹화가 제대로 되지 않아 여름철에는 강우에 의한 표층토양의 유실 및 붕괴로 이어지고, 복구녹화공사를 실시한 비탈면은 황폐화되고 있는 실정이다. 따라서 자연친화적이고 완벽한 복구녹화공사를 실시하기 위해서는 비탈면녹화를 실시하기 전에 현장의 토질특성, 지질특성 등에 대해서 조사하고 그곳에 적합한 복구공법에 대하여 면밀히 검토해야 한다. 아울러 계획된 복구공법의 적용에 있어서도 복구비를 절감할 수 있는 공법의 적용이 필요하다. 조사 결과 토석채취지의 경우 토질이 토사질 또는 리핑암, 풍화토가 대부분으로 이러한 지역은 복구녹화가 완벽하게 이루어질 수 있는 조건이 되므로 여기에 적용하는 공법도 가능하면 간단하면서도 복구녹화가 충분히 될 수 있는 공법의 선정이 중요하다. 아울러 복구녹화계획 및 검토시에는 반드시 산지복구를 전공으로 하는 전문가의 의견을 청취함으로써 그 지역에 가장 적합한 복구녹화공법의 선정 및 완벽한 복구녹화가 가능하게 될 것으로 사료된다.

The purpose of this study was to minimize the forest disturbance around an entry road of a power transmission tower construction site between Taean and Sinsesan, Chungnam. The main study field was classified into existing materials and a GIS, remote sensing analysis, and a field examination. This information was used to identify the most suitable entry road using a degree of green naturality map, eco-naturality map, actual vegetation map, and a forest state map as the existing materials. Also, the study used an normalized difference vegetation index, altitude and slope map in order to make the evaluation materials which used an remote sensing image, and GIS. This data was used to choose an optimum area, and diagnosed the current condition of the vegetation with a field survey of the area. It analyzed vegetation structure, species diversity, the age of trees in a field examination. Subsequently, we proposed four area types based on the analysis results--preservation area, transplantation area, restoration area and development area. As a result, the preservation area was categorized into 8 grades, according to the degree of green naturality, large area of breast diameter at Pinus densiflora community, competition area of Pinus densiflora and Quercus spp. and Quercus spp. community of over 20 years old. A transplantation area established 46 optimum areas according to the GIS analysis and vegetation investigation results. Vegetation restoration plan for disturbance area should be made based on ecological value of existing vegetation to worthwhile area as Quercus spp. mixing forest proposed. The development area selected a ecological worthless place as an artificial forest where Pinus densiflora and Pinus thunbergii growth is poor. This research results suggest that restoration of vegetation will be possible in the real world. Also, ecological restoration guidelines will be made through building and analyzing data base and routine monitoring of transplantation and restoration area.

Purpose: Temperature in urban areas increase much more than suburban areas and it is called urban heat island (UHI) phenomenon. There are several solutions to control UHI phenomenon such as green roof system, water space construction, and cool roof system. However, application of green roof system and cool roof system to some of the buildings which compose the city has a critical limit. Therefore, in order to diminish the temperature rising and UHI phenomenon due to climate change of the city, it needs to approach from the viewpoint of site or city, rather than the viewpoint of individual buildings. This study is aims at analyzing UHI phenomenon by characteristics of surface materials and suggesting the solutions to reduce UHI phenomenon by types of complex. Method: Literature reviews were conducted to analyze the cause, mitigating plan, and recent trends of UHI phenomenon. For the simulation analysis, the type of complex was classified 3 representative complex. Based on measured reflectivity, simulation about UHI phenomenon was conducted by setting 4 strategies; albedo of roof, road pavement, green roof system, and vegetating around buildings. Result: As the results of simulating the UHI reduction factor by types of complex, it showed that the effect of temperature reduction on the building roof layer is more effective than adjusting the reflectivity of buildings such as green roof system, planting near the buildings in both the detached house complex, apartment complex, and commercial complex.
