현재 리모델링 시장은 전체 건설시장 규모에 비해 매우 적은 비중을 차지하고 있으나 점차 그 비중은 확대될 것으로 기대한다. 또한 공동주택 리모델링 시장은 자원의 재활용 및 수익성 측면에서도 재건축을 보완할 대체시장으로 부상할 것으로 예상한다. 그럼에도 불구하고 리모델링보다 재건축에 대한 선호도가 높은 이유는 재건축이 리모델링보다 경제성 측면에서 유리할 것이라는 막연한 기대감과함께 리모델링의 구조적 신뢰도 결여, 리모델링 평면의 제약, 리모델링 사업 수행 경험 부족 등에서 그 원인을 찾을 수 있다. 그러나 분석 결과와 같이 실제 사업성 측면에서 리모델링이 유리한 단지가 많을 것으로 예상되는 만큼 사업 주체인 조합에게 합리적인 사업성 분석을 통하여 자산 가치를 높이는 최적의 사업방안을 제시하는 것이 필요하다. 이를 위해 리모델링에 대한 포지셔닝 구축을 통한 합리적인 마케팅 방안 제시가 요구된다고 하겠다.

Due to a waste of energy in korea, about 525,000 which are 75 percent of total buildings are at least 15 years old buildings that need remodeling. There are two current remodeling systems. One is a remodeling system to reduce a waste of resources from the reconstruction. The other is a green-remodeling system aimed to energy savings and reducing environmental costs. This study is to analyze quantitatively these current systems with respect to the cost-benefit caused by the life cycle and suggests the political and institutional implications through the interpretation of the results. For a quantitative analysis, we analyzed reducing maintenance costs and rent benefits with simulation by using opportunity costs, construction costs, plan costs and supervision costs as expense variables and using the reduced floor area ratio, institutional incentives, energy, water resources and certified emission reduction(CER) as benefit variables. As a result of the empirical study, the green-modeling was more beneficial in the field of environment such as the energy savings, however, the final benefits of remodeling which has no green building certification costs but more floor area ratio incentives were more economical. The green-remodeling system focused on reducing environmental costs and energy savings needs a equatable institutional incentive system.

현재 국내 주택의 근간을 이루는 내력벽식 공동주택은 구조적 한계로 인해 단수명화되고 있다. 이로 인해 발생하는 재건축은 막대한 자원 및 에너지 소비와 건설폐기물로 인한 환경오염을 유발하고 있다. 정부는 이러한 문제 해결의 방안으로 리모델링이 가능한 라멘구조를 유도하는 인센티브 제도를 시행하고 있다. 따라서 새로운 개념을 적용한 라멘구조의 공동주택을 위하여 개발된 복합PC구조인 Green Frame은 내력벽식 및 기존 라멘조식 공동주택이 리모 델링이 어렵다는 단점을 개선할 수 있을 뿐만 아니라 공사기간 단축이 가능할 것이다. 그러므로 본 연구에서는 Green Frame의 특성과 절대공기를 분석하고, 구조별 공동주택의 골조공사 공기와 비교 분석하여 차이점을 규명하였다. 그 결과 Green Frame을 공동주택에 적용할 경우 공기단축이 가능한 것으로 나타났다. 따라서 건설공사에서 공기는 매우 중요한 요소로 향후 성공적인 공동주택의 사업을 위해서 중요한 핵심기술로서의 역할을 할 수 있을 것으로 사료된다.

Purpose - This paper attempts to identify the problems and limitations of a market maintenance project conducted according to the 「Special Act for the Development of Traditional Markets and Shopping Street」 and to present a revised direction for the special law and lay the groundwork for market maintenance projects to be promoted smoothly. Research design, data, and methodology - The revised direction for the legislation and the proposal were written based on an investigation of the problems and the legal system, and proposed measures for market maintenance operation and system improvements to derive the improvements needed for market maintenance projects. Results - A market maintenance project has been conducted as a means to reinvigorate traditional markets that are economically depressed, and to revive the local economy. It was largely conducted in the form of reconstruction and redevelopment and represents the interests of landowners and merchants. Thus, it is most likely to contribute to the gradual disappearance of traditional markets. First, as part of a market maintenance project, many companies are building multipurpose buildings or high-rise residential buildings to increase profits. In these high-rise buildings, they can raise rents, which may not be affordable for some existing small businesses. To solve such problems, the large-scale store registration requirement needs to be relaxed or abolished once the market maintenance project is completed. If the large-scale store registration requirement is to be abolished, the term 'large retail store' should be changed in the 「Special Act for the Development of Traditional Markets and Shopping Street」. After registration, the Small and Medium Business Administration should train merchants, offer consultations, and support events, to the extent that the existing traditional market management modernization project permits, and further continue to manage and support its ongoing activities. However, unless large-scale store registration is abolished, adding an exception clause in the special law to relax large-scale store registration criteria, and permitting changes to building use is another option. At the end of a market maintenance project, empty stores should be purchased by the Small and Medium Business Administration, and local government, etc., at the actual construction cost, to utilize them as public rental shopping areas, which in turn may be re-utilized as a temporary market for another market maintenance project. The second problem in market maintenance projects is merchant-protection. Currently, the special law prescribes that a temporary market be created for merchants to conduct business during the rental period of a market maintenance project. Conclusions - In reality, a market maintenance project is conducted usually in big metropolitan cities with 500,000 residents or more. The main building type created under these projects is a multipurpose building. For this reason, it is very difficult to secure a location for a temporary market in the surrounding area of such a project. To solve this problem, this study suggests 'public rental shopping areas' as mentioned above.

Multi Housing design has not considered the remodeling even at the beginning of the construction. This severely hindered systematic maintenance, providing fundamental causes of consuming society. In general, in about 20 years when the buildings become too old, they are brought down or removed with a trail of waste left behind. In addition, since the current remodeling or future remodeling type is a general remodeling that leaves only a frame, some question the role of the remodeling as a solution to the reconstruction from economically and environmentally efficient aspects. This study intends to find a solution for long-life span multi-family housing design, promoting sequential remodeling by stating the life cycle of components. Problems were identified by analyzing joints, design and construction of multi-family housing based on the previous researches. Conclusion from characterization of the design plan according to joint parts can be summarized as the following firstly, the problem of the wet was seen in joints between the structure and a finishing materials and ones between separate finishing materials. Secondly, the problem of overlap was frequently seen in joints between the structure and a door/window, ones between a door/window and a finishing materials, and ones between a finishing materials and an electrical/mechanical device.

In order to solve the current shortage of parking spaces, and redesign the main gate area of the U University, the research investigated some cases of other schools located in Seoul which actively constructed multi-purpose building structures. Those schools are considered to be good samples showing their efforts to fulfill the needs of more parking spaces in their campuses, and to cover with the growing needs of multi-functioned facilities accommodating services of academic affairs, reading room spaces, and amenities. With the investigation, the research finded out the current trends of campus developments from the sample schools, such as underground parking facilities connected with multi-purpose buildings along the main arteries of campuses. Following the trends the research thoroughly examined the present conditions of our school and tried to make some possible alternatives for the facilities. Under the conditions, the research suggested 1)to construct underground parking lots accepting around 1,000 cars under the ivory tower square located in front of University Administration Building, 2)to develop a big-scaled open square at the university main gate, and 3)to build a multi-purpose structure along the main street of the campus, which included administration services, studying spaces, and some commercial facilities.

This study is to find out the characteristics of the changes of the site layout in Beopjusa which was built on Maitreya faith in the Shilla.. According to the analysis of it in this study, we make conclusions as follows; 1) The reconstruction of Beopjusa means a start in Dhamalsama(法相宗) and then it was supposed to be Buddhist temple which was formed by intersecting axis of centering around a wooden pagoda(捌相殿) with a main Buddhist hall and a lecture hall. 2) After the middle of Koryo dynasty, Beopjusa was changed to building layout of intersecting with Yongwabojeon(龍華寶殿) and Daeungbojeon(大雄寶殿) because of harmony with Avatamsaka(華嚴宗) and Dhamalsama centering around Avatamsaka. 3) The buildings of Zen Buddhism was built in the early Chosun dynasty owing to a prevalence of Zen Buddhism in the late Koryo dynasty. And since 17th century, Buddhist halls were each built in their a faith system according to interpenetrated Buddhism(通佛敎). 4) The courtyard type of mountainous district was made on interpenetrated Buddhism. On the other hand, the site layout of Beopjusa is being maintained by centripetal spatial organization through the wooden pagoda as object.

The $18^{th}$ century's Industrial Revolution brought about influx of commerce, industry, and agricultural population into the urban areas, entering the $19^{th}$ century. Quality of rural communities declined, and the exploding population in the cities gave rise to various problems. 'Mietskaserne' Blockhousing was constructed by the 'Hobrechtplan', but led to social problems such as poor living conditions, insufficient sunshine due to overcrowding, slums due to incomplete urban infrastructure, epidemics, and so on. Starting in the early $20^{th}$ century, Berlin has driven forward a remodeling plan under the motto of 'critical reconstruction (kritische Rekonstruktion)'. It is performed in the place, which represents the vicissitudinous history of Berlin with site plans coexisting past with presence, using modern vocabulary of architectural forms. Reconstructing a city is a process which not only raises the economic value of each building consisting a city, but also a redevelopment process that brings out cultural value of an era. When a new era emerges buildings get reconstructed or rebuilt, and thereby form the identity of a city by reflecting its society, culture, politics, economy, and history. Old German architecture were not destroyed or rebuilt recklessly just by the fact that they are functionally or aesthetically outdated. Each building is treated as precious cultural heritage reflecting the history. This is how Berlin is being transformed today.

Purpose - Clarifying one of the biggest public Hospital Costs and incomes according to patients' case mix. It leads to prepare financial information about pubic medical tariffs and hospital operational costs. Research design, data, and methodology - This study calculates the costs both, with and without taking into account capital costs. This holds for comparison of hoteling based on case mix in all medical procedures. The checklists were reviewed and filled by reviewing accounting documents of the hospital, warehouse exclusion list, and daily books of laundry and CSR. Data was analyzed descriptively by using Excel. Results - In both cases, the hospital is losing in terms of hoteling. Because the buildings and equipment are new, this loss is not tangible. However, this will be revealed when costs of reconstruction and replacement of equipment. The loss rate per day of hospitalization was 569318 Rials for Coronary Care Unit (CCU), 528171 Rials for Post Intensive Care Unit (Post ICU), 474570 Rials for ICU, 233183 Rials for Post CCU and 204803 for Surgical ward. Conclusions - Income of hoteling was lower than its costs. ANOVA showed a strong relationship between case mix and hospital costs as well as case mix and its income. This suggests that optimal case mix can minimize the costs and maximize income.
