As the number of small households (1 to 2 persons per household) in Korea gradually increases, so does the importance of housing supply policies for small households. In response to the increase in small households, the government has been continuously supplying urban housing for these households. Since housing for small households is a sales and rental business similar to apartments and general business facilities, it is important for the building owner to calculate the project's estimated construction duration during the planning stage. Review of literature found a model for estimating the duration of construction of large-scale buildings but not for small-scale buildings such as urban housing for small households. Therefore this study aimed to develop and verify a model for estimating construction duration for urban housing at the planning stage based on multiple regression analysis. Independent variables inputted into the estimation model were building site area, building gross floor area, number of below ground floors, number of above ground floors, number of buildings, and location. The modified coefficient of determination (R_a²) of the model was 0.547. The developed model resulted in a Root Mean Square Error (RMSE) of 171.26 days and a Mean Absolute Percentage Error (MAPE) of 26.53%. The developed estimation model is expected to provide reliable construction duration calculations for small-scale urban residential buildings during the planning stage of a project.

도시재생사업은 주민참여를 중심으로 커뮤니티를 재생시키려는 목적을 갖지만 공람, 공청회 등 현행 주민참여방식은 형식적 수단에 불과하다는 한계를 지니고 있다. 이에 따라, 본 연구에서는 정책결정자, 전문가 그리고 주민이 서로의 생각을 교환하고 이해하는데 유용한 의사소통 도구 및 재생사업의 적극적인 추진 매개체로써의 공공참여 서비스 모형을 수립함으로써 능동적인 공공참여를 이끌어낼 수 있기를 기대한다.

본 연구는 '01년 이후 민간 제휴업체에 의해 추진되고 있는 주택공사 사이버아파트 운영체제의 문제점을 분석하고, 향후 기술발전 추세와 정부방향을 검토하여, 바람직한 운영체제를 제시하였다. 아파트 단지 홈페이지 위주의 사이버아파트는 향후 홈네트워크 기반의 디지털홈으로 발전될 것으로 예상되며, 정부도 지능형 홈네트워크를 차세대 10대 성장동력산업으로 선정하는 등 육성의지를 표방하고 있다. 현재 사이버아파트 운영은 입주자 특성에 부합하는 정보제공 불가능, 관리정보의 온라인 제공 곤란 등 운영상 문제점이 나타나고 있으며, 이는 아파트 단지 홈페이지가 활성화되지 못하는 원인으로 작용하고 있다. 이에 따라 사이버아파트 구축현황을 분석하고 효율적인 운영 체제를 제시하였다.

Time management is important in construction management Especially, in the high-rise apartment housing projects, it is very important to expedite the construction progress in order to meet the planned schedule. The objective of this paper is to propose the baseline for the progress rate using work volume and man $\cdot$ hours performed at work activity level. The work volume far each activity is transformed to the weighted value compared to total work volume for the floor Therefore, a progress rate for an activity is calculated by multiplying a weighted value and work volume. A progress rate for a floor and a building can calculated in this manner, respectively.

This study is aiming at estimating the demolition cost of deterioration housing by the rational method in order to provide for the demolition and new build project of the rental multi-family housing of LH. We investigated the actual state of demolition construction and work process of small size housing, and analysed an actual condition of estimation for the demolition cost through an advice by the expert of construction cost estimate. Furthermore, the 'estimation standard for the predetermined amount', 'estimation standard for the disposal cost of construction wastes' and precedent studies in public construction work were considered. As one of results in this study, cost accounting system, breakdown system and construction cost for the demolition work based on the standard of estimate were proposed and the predetermined amount of demolition construction for the multi-family housing with 2 or 3 floors could be produced by them. Eventually, It is estimated that the demolition cost per a multi-family housing is about 18,331,000(won) and 104,000(won) per floorage($m^2$). To the details, the result indicated that the direct demolition cost needs about 14,339,000(won) per a multi-family housing and the consignment disposal cost of wastes needs 3,992,000(won) per one. The results of the study will be used as the fundamental data to estimate the project cost in the phase of budget establishment for demolition and new build project of the deteriorated rental multi-family housings, and also cost accounting system of demolition construction and breakdown system are expect to be used effectively at the ordering of public construction work.

As the domestic housing supply problem has been resolved, the apartment construction market has shifted to a consumer-oriented market that wants high quality, and in particular, expectations in the area of finishing quality have increased. Looking at the status of complaints regarding apartment housing defects supplied by Korea Land and Housing Corporation, tile-related complaints are the type occurring the most frequently. While the Ministry of Land, Infrastructure and Transport(MOLIT) is making an ongoing effort to reduce complaints related to defects, through approaches such as drafting amendments to 「Investigation of defects in apartment houses, calculation of repair costs, and standards for determining defects」, the provision of preventive measures has been insufficient. In addition, by reviewing studies, there has been insufficient research to construct a classification system after deriving the characteristics of each type using the qualitative knowledge of experts, various quantitative indicators, and suggesting measures for reduction according to the causes of each type. Therefore, this study will reflect qualitative indicators to use the AHP analysis that makes it easy to identify the relationship between defects by surveying construction experts. Then, by visualizing the weight of 'Possibility of recurrence after repair,' 'Degree of difficulty in repairing defects' and 'Fault frequency' using a radial graph, we will analyze the characteristics of each type of tile construction defect and establish measures for reduction according to the cause. This will improve the quality of the living environment and contribute to the establishment of a system for smooth defect management and reduction of defects in apartment tile construction.

Usually feasibility analysis in a narrow sense is a economic analysis of project. Feasibility analysis focused in this study is confined to the matter of finance. Many studies have been executed in qualitative element which include decision-making process or prediction of housing market. But it is difficult to find economic analysis related to characteristics of planning. In this study, floor area ratio, selling area ratio and term of works are adopted as the Characteristics of Planning. So, the purpose of this study is to analyze the Influence of the characteristics of planning on the cost of apartment by means of multiple regression analysis and what-if method.

In the event of a housing sale guarantee accident, the Housing and Urban Guarantee Corporation shall be responsible for the guarantee by refunding the moving-in money unless there are special circumstances to the contractor. The Housing and Urban Guarantee Corporation may refuse to perform the refund based on the Terms and Conditions Regulations Act, but disputes continue to arise between interested parties in this regard. Therefore, the purpose of this study is to study the problems and improvement measures for legal issues related to the implementation of the refund. First, the issue of guarantee effectiveness and scope of guarantee under the Terms and Conditions Regulation Act. Second, the problem of guarantee contract for conditional third parties of Housing and Urban Guarantee Corporation. Third, the problem of the attitude of the existing precedents of the Supreme Court was examined. As a result of reviewing these legal issues, it was confirmed that the interpretation of terms and conditions according to the implementation of the refund is being interpreted in accordance with the principle of good faith, but according to individual cases, precedents can be divided into positive and negative judgments. In addition, despite the fact that the housing pre-sale guarantee is a guarantee contract for a conditional third party, it was confirmed that the buyer suffered damages in good faith through active disputes with the interested parties. Accordingly, the Housing and Urban Guarantee Corporation proposed an improvement plan for roles and cooperation items to meet the purpose of establishment for the stability of the customer's housing.
