The changed Korean government law associated with the public apartment housing supply, so called the $^{\circ}{\AE}$Apartment Sales Price $Cap^{\circ}{\phi}$, requires new system for estimating construction cost in order to set appropriate price. A model apartment project was carefully designed and its construction cost were analyzed in many different ways. Based on the analyses outcomes, 1,028,000 Won/m2 (excluding cost for underground parking lot) is the most appropriate Price Cap for a smaller than $85{\beta}{\geq}$ apartment unit. Further, it was revealed that the price have to be adjusted reflecting such factors as underground size; structural system; external complex quality; and consumer preferences. Findings from this study will enable the Korean government to realize faster and better application of the related laws. The methodology for obtaining appropriate apartment construction cost will also benefit for future researchers.

The Qualitative improvements of outdoor spaces are unsatisfactory in comparison with that of indoor environment in existing apartments. Lately construction companies are differentiating the outdoor spaces of apartment complexes to meet needs of residents. However, high-rise buildings inherently have limitations on providing exposure to the outdoor settings and inappropriate lightings could have serious impacts on physical and psychological health of residents. Therefore, the purpose of this study is to provide useful information for the luminous environment of outdoor spaces through the analysis of current apartment complexes' lighting plans. Outdoor space of branded apartment complexes in Seoul, built after the year 2003, were researched. Through site visits, illumination level and lighting plans were investigated classified into entry area, passage area, plaza, rest area, exercise area, and play area. With the result, illumination level of apartment complexes researched was lower than KS illumination standard in all areas and the lighting plans were mostly shown in different condition of first intended lighting plan because of insufficiency of maintenance in lighting system. Therefore, it is need to provide better luminous environment to make outdoor space more lively and energetic at the night time.

The purposes of this study were to make clear the present condition of the TVOC and HCHO concentration after remodeling in apartment houses and to analyze the relation of concentrated ascension and remodeling elements. The field measurements of TVOC and HCHO concentration were carried out in 4 subject apartment houses according to the Korea Test Method Standard for Indoor Air Quality. The results are as follows; the TVOC concentration after remodeling ranged from mean 0.35ppm to mean 5.08ppm and increased of 0.35$^{\sim}$5.08ppm. The concentration of 3 subjects exceeded the Indoor Air Quality Management standard for the newly-built apartment houses (0.7ppm). The HCHO concentration after remodeling ranged from mean 0.13ppm to mean 0.43ppm and increased of 0.06$^{\sim}$0.26ppm. The concentration of 2 subjects exceeded the Standard (0.16ppm). As results of analysis on the relation of concentrated ascension and remodeling elements, the amount and the types of finishing materials and adhesives affected concentrated ascension. Also, production method for installed or purchased furniture had certain effect on the TVOC and HCHO concentration ascension.

The purpose of this study is to provide basic data needed for planning apartment community spaces in order to vitalize rental apartments. Indoors community spaces of six rental apartments in Seoul and Gyung-gi were examined. The results are as follows. First, layout types of community spaces in rental apartment complexes were researched and it was found that there are singular types and block types. Depending on the layout type, the space could function as an element to closely associate residents with each other. Second, child care spaces were planned to conveniently utilize the space with space plans, and furniture and appliance plans adjusted for children's characteristics. On the contrary, elderly spaces lacked exercise equipment and subsidiary facilities, and educational spaces caused inconvenience as they did not take into consideration the user characteristics. Third, although indoor community spaces of rental apartment complexes were planned to hold child care spaces, elderly spaces, educational spaces, and neighborhood spaces according to the legal standards of installation, the operation of these facilities were problematic.

This study is a preliminary study to develop design guidelines on shared spaces of apartment for healthy housing. It was tried to set the basic direction of the guideline development by comparing and analyzing related literatures based on the previously identified evaluation indicators of healthy housing of apartment. The major findings were as followings: 1) based on the research conducted before, the characters of shared spaces for healthy housing were classified as physical, mental and social dimensions. 2) According to the comparison and analysis of relevant standards and guidelines, focuses were mostly on the physical dimension, particularly on the human traffic lines of the convenience attributes. Other focuses were on the attractiveness of the apartment complex of the vitality attribute under the mental dimension, and community facilities of the residential stability attributes under the social dimension. Therefore, it was identified that it is required to take complementary measure regarding mental and social dimensions, and design concrete steps to include different attributes of each dimension, in order to develop comprehensive guidelines for shared space.

The purpose of this study is to investigate the planning of the community spaces for sustainable apartment complex under the aging society. For this, it is needed to identify the practical meaning of community spaces for elderly residents. In many cases, existing apartments' community spaces have been designed without considering the elderly. In order to develop successful environment for aging society, it is necessary for us to precisely review how elderly residents are changing their needs. Survey and depth-interview methods were used for data collection of this study. This study was performed in the five subject apartments located in Haeundae new town, Busan. In planning of community spaces for sustainable apartment complex in the aging society, 1) The population of the elderly in apartment complex has been increased with progress of the aging society, and it has been necessary to enlarge and consider the aging-friendly community space. 2) When the community space is located in a good accessibility, visual openness, multipurpose composition and the center of complex, it was investigated that the degree of its usage was high. 3) Common apartment complex for the elderly was deficient, and the composition and the layout of community spaces were needed, which included sports facility, spaces for leisure culture and study. This study could be utilized as basic data for designing community spaces in apartments from the perspective of sustainable community.

Management process of apartment buildings construction has increased because the after service of construction company meet the needs of customers. Many defect data, which was inspected by construction company or customers before moving into a new apartment house, were classified by field engineers and then communicated to corresponding subcontractors. The classification process needs to be performed by an expert engineer because there is so much data, it is unfeasible to complete in a short period of time. For this classification process, an automatic classification system using case base reasoning (CBR) should be considered. This research proposed a defect management system with automatic classification system using CBR. This constructed defect management system consists of cyber after service system for tenants and the whole defect management process of construction, preservation and management of apartment buildings. This system could improve the efficiency of expert work in terms of time and accuracy, as well as helping laymen users to conduct defect classification work as experts do.
