This study was aimed at determining the characteristics of circular multi-family housing under the assumption that the shape of a residential building affects local identity. A total of six case studies were included in this study, three case studies on idle historical industrial facilities turned into residential buildings and another three on multi-family housing located in newly developed residential complexes. The study drew its conclusions as follows. First, the design of circular multi-family housing was intended to maximize security and defense from the outside in older times. This was later developed as the terrace house style with geometric urban squares designed under the urban planning of the Baroque period. This evolved high-density housing with a courtyard in the center offering a green open space, with the aim of restoring a sense of humanity. Second, the six case studies on circular multi-family housing were analyzed from the viewpoint of each factor of local identity, including historical and cultural, landscape, and community. Third, the historical and cultural elements of circular multi-family housing are found in some unused historical industrial facilities remodeled into residential buildings. They provide new capabilities and shapes desired by society at a given time, while maintaining familiar styles and elements of history, integrating a legacy of the past into the present. Fourth, circular multi-family housing with unique shapes and structures often become landmarks of a region with their distinctive appearance against a uniform urban environment and the monotonous scenery of residential complexes. They also show a high level of visual awareness with the distinctive shapes made possible when new elements are added to a historical exterior. Finally, circular multi-family housing with courtyards in the center prompt social contact between inhabitants, especially with dormitories and rental houses for the low-income bracket, which provide a small individual units with high use common space. Circular multi-family housing are planned in a manner similar to a small village or a city. They are designed to enhance sense of community, allocating various public amenities and provide cultural and commercial spaces on the ground floor and courtyard areas.

In order to reduce greenhouse gas emissions in recent agricultural energy and increase the energy self-sufficiency rate of each farmer, it is extremely important to expand the supply of solar energy using unused space of agricultural facilities, roof. This study surveyed and analyzed the environmental and administrative factors such as problems according to the structure, azimuth and latitude of broiler houses and stability of standard broiler houses required to use broiler house roof based on the poultry houses in Sangju-si. The results can be summarized as follows: 55.6% of the solar energy facilities of according to the classification of arable lands of broiler houses were available, and 31.7% of them were available by classifying according to the azimuth. However, 20.6% of them were available in the survey considering all the arable land and azimuth. In the roof inclination of the broiler houses, from 20 to $25^{\circ}$ was the most common, 30 broiler houses. The broiler houses with the roof inclination more than $20^{\circ}$ accounted for 63% of the total. It was considered that the inclination was generally proper. In the structural safety, only 3 broiler houses that were constructed as a standard broiler house were available. In practice, all but one broiler house was inappropriate to expand the solar energy project using roof. The solar thermal facility weighed $63.6kg/m^2$ in total: the frame and solar thermal collector weighed $27.8kg/m^2$ and $35.8kg/m^2$, respectively. The standard broiler house required to be internally reinforced. This study suggested a plan for internal reinforcement and a feasible plan because there were problems with structural safety when installing solar thermal and photovoltaic systems.

콘크리트의 화학적 침식은 콘크리트 구조물의 내구성 감소로 이어져 문제가 되고 있다. 현재 사용되고 있는 콘크리트 표면보호재의 내구수명이 짧아 유지보수에 많은 비용과 노력이 요구되고 있다. 한편 국내 산업시설에서 유황의 부산량이 늘어나고 있으나, 소비량이 한정되어 있어 잉여유황이 증가하고 있다. 따라서 본 연구에서는 유황폴리머를 콘크리트의 표면보호재로 사용하기 위한 연구로써 채움재의 종류 및 양생조건에 따른 역학적 특성을 평가하였고, 유황폴리머에 대한 유해성을 평가하였다. 압축강도 평가 결과 채움재의 치환비율이 40%까지 증가할수록 압축강도 또한 증가하였으며, 채움재의 종류에 따라 양생온도 $40^{\circ}C$ (SS, FA)와 $60^{\circ}C$ (OPC)에서 높은 압축강도를 나타냈다. 기건양생과 수중양생의 압축강도 차는 미미한 것으로 나타나 양생 시 수분에 의한 영향은 크지 않은 것으로 나타났다. 부착강도 평가 결과 채움재의 종류와 무관하게 기건상태 $40^{\circ}C$에서 가장 높은 부착강도를 나타냈으며, 수중양생시 기건양생에 비하여 부착이 되지 않는 것으로 나타났다. 또한 $60^{\circ}C$에서 양생한 공시체의 경우 온도에 영향을 받아 변색 및 잔갈림 등이 나타냈으며, 채움재의 종류에 따라 치환 비율 20% (SS, FA) 30% (OPC)에서 가장 높은 부착강도를 나타냈다. 유해물질 용출시험 결과, 유해물질이 용출되지 않아 유황폴리머를 활용한 표면보호재의 유해성이 없는 것으로 판단된다. 본 연구범위에서 검토한 결과, 유황폴리머를 표면보호재로 활용하기 위해서는 규사를 20% 정도 치환하여 배합하고 $40^{\circ}C$의 기건상태에서 양생하는 것이 가장 적절한 것으로 판단된다.
