The work of constructing apartment housing involves various fields of industry that are linked to each other, and is based on a design document prepared by multiple technicians and architects. Consequently, design errors, material flaws or faulty construction works can cause defects, which sometimes overlap with each other. Construction companies should repair any defects found in a completed building within a specified period of time, and to do this, should establish a business plan by efficiently predicting the cost of defect repair. As it is very difficult for companies to accurately predict the occurrence of defects, historical performance data is used as a base. For domestic apartment housing units, data on the cost of defect repair is insufficient, so there are hardly any methods that can be used to make precise predictions. Therefore, the intent of this study is to develop a model that can predict the cost of defect repair by supply type and area, based on historical performance data with ten years worth of post-completion.

전세제도(傳貰制度)는 공공임대주택(公共賃貸住宅)이 존재하지 않고 제도금융권의 주택금융이 미약한 상황에서 유지되어 온 우리나라 특유의 주거점유형태(住居占有形態)이다. 그러나 불완전한 우리의 주택시장 여건하에서 전세임대차(傳貰賃貸借)에 따르는 위험부담이 임차자(賃借者)에게 전가되는 등 불필요한 사회적 비용을 초래하고 있다. 따라서 현존의 전세제도(傳貰制度)를 개선하기 위하여 공공임대주택(公共賃貸住宅)을 늘리고 월세전환(月貰轉換)으로의 유인책을 제공하여야 한다. 아울러 20조(兆)원이 넘는 전세보증금(傳貰保證金)을 주택부문 자금으로 쓸 수 있도록 전세기금(傳貰基金)을 설치하는 등 전세제도(傳貰制度)를 개선하여야 한다. 종국적으로 전세제도(傳貰制度)가 사라지더라도 사회 일각에서 우려하는 저축감소효과는 거의 없을 것이다.

Development Charge System was introduced in 1989 to recapture development gains, however, it has been revised more than 20 times since then. The reason for such frequent revisions was that estimating development cost was too composite and indefinite. Therefore it is required that estimating method of development cost should be simplified in order to minimize conflicts among diverse parties. To support the recent revision of 'Restitution and Development Gains Act', this study verified several alternatives of applying standardized costs per area under specific size of development and suggested policy implications. For analysis data, 9,362 Development Charge and cost data of si gun gu for recent 3 years were used. The results showed that dividing Seoul Metropolitan Area (SMA) and non-SMA made a significant difference and definite divisions among regional groups. The result of this study could minimize social conflicts as well as contribute in realizing the public concept of land policy by revising Development Charge System.

This study aimed to assess the rental housing ABS in Korea, and to suggest ways of improving the structure of existing rental housing ABS. Thus, the three major assessment for existing public rental housing ABS case can be summarized as follows : First, when viewed in terms of the accounting treatment, rental housing ABS which use the future receivables as underlying asset, can not enjoy off-balance-sheet effect. Second, when viewed from the point of financing costs, the rental housing ABS interest rate being higher than unsecure bond is very unreasonable nevertheless the ABS being off-balanced. Third, when viewed from the liquidity effect, the originator (LH) use the ABS as a means of diversifying funding in a serious liquidity crisis situation. The Improvement of rental housing ABS based on the evaluation results can be summarized into two broad. First, it is a plan to handle the off-balance-sheet effect in a way of changing the accounting treatment of rental payment. Second, it is a plan to reducing the structuring cost and interest rate in ways of multi-asset securitization structure, self-trust structure, and adopting legal CB structure.

In the resent years, the importance of VE (value engineering) and LCC (life cycle cost) analysis for apartment building construction projects has been fully recognized. Accordingly theoretical models, guidelines, and supporting software systems were developed for the value engineering and life cycle cost analysis for construction management including large building systems. However, the level of consensus on VE and LCC analysis results is still low due to the lack of reliable data on maintenance. This paper presents time dependent LCC model based value analysis method for rational investment decision making and design alternative selection for construction of apartment building. The proposed method incorporates a time dependent LCC model and a performance evaluation technique by fuzzy logic theory to properly handle the uncertainties associated with statistics data and to analyze the value of alternatives more rationally. The presented time dependent VE and LCC analysis procedure were applied to a real world project, and this case study is discussed in the paper. The model and the procedure presented in this study can greatly contribute to design value engineering alternative selection, the estimation of the life cycle cost, and the allocation of budget for apartment building construction projects.

A smart-home is considered as one of most important alternatives of future homes with rising attention on IT technologies. The purpose of the study was to analyse the trend of smart-home technologies and to see how they reflect changing lifestyle needs. The research method includes a content analysis and a case study. The result shows that 'automation' functions are 35% of total. 'Health'(19%) and 'entertainment'(15%) functions are followed by 'Energy'(15%), 'Information'(11%). and 'relationship(6%).' This study is meaningful in that it examined smart-home technologies centering on the needs of residents rather than technological perspectives. Further researches on specialized smart-homes should be continued reflecting segmented needs of residents such as a medical home and a energy saving home etc.

In recent years, the proportion of medium and small-sized apartments within the housing market has seen a noticeable increase, alongside a corresponding rise in disputes related to construction defects. Such disputes are most prevalent in the finishing works phase of construction, which not only are frequent in occurrence but also impose significant repair costs. Furthermore, there is a noticeable scarcity of research focused on the quality management of finishing work defects prior to the completion of construction. Addressing this issue necessitates a methodology capable of preemptively identifying defects by analyzing their frequency and associated costs across various defect types. Consequently, the aim of this study is to propose a risk assessment methodology by conducting an analysis of defect cases across 3,299 apartment units, considering aspects such as frequency and severity. The outcomes of this research endeavor are expected to offer practical management strategies to enhance the quality of apartment finishing works and serve as an academic foundation for the enhancement of construction management systems pertaining to apartment finishing works.

The purpose of this study was to explore the attitudes about the management service charge in multi-family housing. Recently, increasing needs of urban families in residential housing management services were apparent in many studies, but the way that they charge for the management services was not dear. Research method was social survey with questionnaire from 484 residents and 84 housing managers of multi-family housing in Seoul and new town area. Research results showed that residents recognized the management services should be free of charge or imposed actual expenses, but managers recognized the management services as charged services. To provide efficient housing management services for residents in multi-family housing, human resources should be inputted. Therefore, this study suggested that the participation of residents in housing management service is recommendable as a way of lessen the economic burden of management service charge, but also to have an opportunity to interest in their community activities.

The purpose of this study is to predict the long-term maintenance expense of BTL school projects which were ordered from the Ministry of Education and Human Resources Development and each Metropolitan and Province Office of Education. For conducting this study, the adapted research method includes a case study of BTL school projects ordered from Seoul Metropolitan Office of Education in 2006. After examination of initial investment based on each $school^{\circ}{\phi}s$ operation account, it estimates maintenance expense and long-term maintenance expense. Also it compare using two methods: one is the long-term maintenance expense estimation in apartment houses and the other is AEAM(annual equivalent amount method). The results of this study are as follows: 1) It is analyzed long-term maintenance expense rates of each BTL school. As a result, it is construction(14.0), civil(1.4%), mechanical(6.5%), equipment(6.5%), electronic(11.0%), fixture(5.1%) and the rest(1.0%). 2)It is applied using two methods: one is the long-term maintenance expense estimation in apartment houses and the other is AEAM. Finally, It is compared expense deflection per $100{\beta}{\ge}$ in each month.
