The boom of housing market lead to build a lot of apartment houses concentrated on the metropolitan area and developing new city in 1980's made 2,000,000 houses. In this time, quality standards could not be satisfied with consumers' desire due to the policy about excessive supply and come from unexpected defects in the complected buildings. In $1980's\~1990's$, It would be performed on the study for defect prevention in apartment houses. It has contributed in no way to the reduction at the rate of the defect outbreak and the solution of consumers' dissatisfaction by flaws. The reason is that the study related defects is not linked and applied by the managing and controlling system, Therefore, the study will be analyzed out defect information occurred on apartment houses of domestic construction and classified by type features. As a result, it will suggest web-based feed-back system for getting systematic information and the practical use.

Apartment brand has been used as a new strategy in Korean housing market to fulfill customer's changing needs for buying houses. A number of construction companies have succeeded in brand awareness and image building, however, they still struggle to establish brand loyalty and manage brand equity elements in balance. The purpose of this study is to analyze the brand equity building process of apartment products in Korean housing market and determine causal relationships among variables to propose strategies for long-term prosperity of the construction companies. System Dynamics modeling method is applied to describe how variables affect and are linked to each other in terms of building equity and enhancing company profits from customers' brand awareness to brand loyalty. Based on the analysis model, strategies for construction companies depending on their market share were proposed and this may support the company to achieve financial success and competitiveness among its competitors in the fast-changing market.

Apartments amount to 58.3%, the highest proportion of domestic housing types. These apartments' lifespan (approximately 27 years) are one-third of the developed countries' housing lifespan due to the property developers and mass production. It is significantly short-cycle period considering the original physical lifespan of the apartment housing are 60 years. It has caused economic loss and environmental degradation. In recent years, research and development for the long life of the apartment housing has been actively performed, but it is limited on reconstruction and new construction. Reconstruction of existing a number of high-rise apartments is difficult owing to restrictions on the floor area ratio allowing for 40 years limit of decay resistance after the completion. Improving lifespan of the building has recently begun to receive attention as an alternative to remodeling. However, These sort of remodeling techniques tend to be focused on technology developed for the physical life extension. That means developing the techniques about dwelling-unit environment for residents satisfaction are required as well as improving physical construction. The purpose of this study is to propose and verify the Participatory Design Technique which can help the residents as the active participation in the design decision-making process.

Recent new town construction project proouced large numbers of apartment houses using precast concrete (P. C.) panels. l'bst construction companies involved in this project put their management focus on to the individual control of P.C. panel producing plants and the job sites. Little attention was paid to the integrated management of the production. transportation. and im;tallation of P. C. panels. Numerous job site delays experienced in the new town project were largely based on the poor coordination between these three key disciplines of the P. C. apartment construction. This stlldy was initiated with an .intention to improve coordination between these disciplines. Activities of these disciplines were identified and related data were gathered. This was performed through the interv:iews with the personnel involved in P. C. constructlon and through the analy::;is of the related documents and publications. Based on this information. the authors are nolol developing a model IoIhich will provide a foundation for opt:iJnal.ly coorc.inated control of the proouction. transportation, and installation of P. C. panels for apartment construction. In this paper. the authors briefly present intermediate results of this study.

The apartment housing in Korea has been rapidly constructed by adapting the most suitable construction methods as like wall structure, wet and united construction. But most of short-lived equipments usually filled in the structure which has longer life, and it causes not only to make difficult coping with the deterioration of equipments but also to let buildings remained deteriorate themselves. The buildings can be remodelled to slow down the terms of deterioration or reconstructed to give a new life of themselves, although the disposal of wastes or the lack of natural resources still be problems and unsolved that can occurred in pulling down and reconstructing the buildings. Furthermore, it is the time to need keeping with worldwide trends and movements as like sustainability or 'green growth' movements based on low carbon emissions. The researches for Long-Life Housing apartments which has durability and variation have been advanced up to now. Long-Life Housing apartments can separate their structures from equipments and interior or exterior materials of buildings. Therefore equipments or materials of buildings can be easily repaired and replaced with new ones, even if they are deteriorated themselves. Also, the construction process of Long-Life Housing apartments can be independent from the matter of proprietary rights, terms of durability, decision rights and so on. 'The law of Possession and Management of Collective Building' and the 'Regulation of Management of Collective Building' established by each local governments are already legislated for declaring the rights of using and ownership, responsibilities of each parts of apartment buildings. These laws and regulations classify the ownership of each parts of apartment buildings, and divide the ownership with public possession and exclusive possession. Therefore, this study will conduct comparative analysis between 'The law of Possession and Management of Collective Building' and 'the Regulation of Management of Collective Building' and find problems which can be occurred in future construction of Long-Life Housing apartments. It will be helpful to revise laws and regulations.

High-rising buildings are a sort of solution to recent cities. Till now real estate development was concentrated in new development on vacant lots, and it resulted urban sprawl. Generally large cities are confronted with the exodus of industry and population from city. High-rising buildings solve many problems associated with this problem. The purpose of this research is to identify the effect of super high-rise mixed use building project process on apartment price. For this study, the hypothesis is that price of apartments is influenced by project process of super high-rise mixed use building. The study concerned 4 variations of project process that is building permits stage, sale stage, construction starting stage and stage of moving into building. The target projects of buildings are selected by number of floor(over 40 floors) and construction time. And 48 apartment complex are selected around super high-rise mixed use building. This study uses hedonic price function to analysis effect of project process of super high-rise mixed use building. A price of apartments is defined as a dependent variable. Characteristics of residence, complex, district and super high-rise building are defined as independent variables. The results are as follows; first, there is no error in price model of this study. Second, it is found that apartment price was influenced negatively by building permit stage and sale stage of super high-rise mixed use building. But that was influenced positively by construction starting stage and stage of moving into building of that. Third, as the project process of super high-rise mixed use building was proceeded, price of apartments was increased.

Recently, much attention has been paid to the problem such as sick building syndrome, which caused by the indoor air pollutant. Volatile Organic Compounds $(VOC_s)$ and formaldehyde have been considered as one of the main reason that causes indoor air pollutant. This study is for introducing and designing thermal performance of super energy saving building by conducting $VOC_s$ and formaldehyde concentration in the 3Liter house. The results of the measurement for 10 months showed that $VOC_s$ and formaldehyde decreased until the guideline concentration. It took about 7 months, and it appeared right after new construction. However, their levels were showed higher concentration in comparison with the ordinary residential houses (apartment house). The main difference of between newly built 3Liter house and ordinary apartment is their air changes, which are 0.67/h for 3Liter house and 4.0/h for the apartment.

Until now, the domestic construction market has been formed focusing on new construction and reconstruction in the apartment industry. Recently, however, the remodeling market for old structures have shown a tendency towards land shortage and land price increases in the major cities: the reinforcement of regulations regarding reconstruction; expenditure reduction and the solving of environmental problems by regarding old structures is pursuing low costs and maximum efficiency. The interest in remodeling is increasing, however, remodeling has not been successfully initiated in the apartment division for a reasonable period of time. Consequently to acquire mutual agreement for remodeling from the residential occupants. In order to evaluate profitability, it is necessary to set priorities and reasonable criteria for remodelling and to this end, it is also required to assess each fact of remodelling in view of both customers and supplied. Thus, a sample apartment housing complex was analyzed for geographic location, surrounding environment floor area ratio, site area, number of households, number of stories and unit area and thereupon, its remodelling profitability was analyzed to select an effective remodeling method as an alternative case for apartment house owners and remodelling.
