Ministry of Land, Infrastructure and Transport (MOLIT) promote long-life housing to reduce social costs generated by poorly considered rebuilding and extend the life-span of housing. Long-life housing has advantages of durability, floor plan variability, efficient maintenance and ease of remodeling because it is a beam-column structure building. However, long-life housing requires somewhat higher initial construction cost than wall type apartments. It makes increase of long-life housing more difficult. In this study, we compare between wall-type apartment and beam-column structure apartment from Life-Cycle Cost's viewpoint. As a result of the study, long-life housing incurs 18% higher initial cost than wall type apartment, but is 7% more economical than wall type apartment in terms of Life Cycle Cost. Therefore, it is shown that long-life housing could be a beneficial alternative to traditional wall type apartments.

Reclaimed aggregates through waste asphalt are produced and utilized for waste resource utilization. This study conducts quality tests and performance evaluations for mixtures with Rejuvenator applied to reclaimed asphalt concrete. Through quality testing and performance evaluation, the study investigates whether there is any problem in using reclaimed asphalt concrete by replacing general hox mix asphalt. As a result, the values of ordinary hot mix asphalt are similar to those of reclaimed asphalt, suggesting that the substitution does not create critical engineering issues. Using reclaimed asphalt concrete has the advantages of increasing economic efficiency and utilizing waste resources.

The purpose of this study is to investigate the historical changes in popular house form of chuncheon city. 177 samples of the houses built in the period of 1951~1992 were selected. The house structure, size, equipment system were analyzed as well as material, color and types of roof along the historical development.

In this study, we investigated the macroeconomic variables that affect housing prices thus creating a large impact on people's lives as well as the real estate market. For the study, the macroeconomic variables able to influence the House Rental Price (housing price by lease or deposit) were used for an analysis as follows: housing sales price index, household loans rate, total household savings, the number of employees and a multiple regression analysis was performed using a time series for each macroeconomic variable. As a result of the analysis, the House Rental Price was affected by all of four macroeconomic variables. The House Rental Price increased as each variable enlarged. In conclusion, this study may be useful for finding a solution for stabilizing the House Rental Price as well as for the establishment of efficient and sustainable policies for the housing market.

Although the life-spans of most apartment buildings are over fifty years, they are often demolished and retrofitted only after twenty years, in spite of its remaining life expectancy, resulting in economical waste. The purpose of this paper is to estimate optimum remodeling period of apartment buildings using total cost. In this study it is seen that total sum of running cost of life-span on the buildings is about 4.69 times of initial cost till the fifty years of the life expectancy. The optimum remodeling period of the apartment building is thirty years applying the discount rate of $4.17\%$ and the discount rate should be $6.122\%$ to obtain the forty years of the optimum remodeling period. From the sensitivity analysis based on the change of the discount rates, it is seen that if discount rate decreases the optimum remodeling period can be extended, or vice versa. As a result, a time of the demolished and remodeling can be expected and the basic data can also be established for lengthening life-span of the apartment buildings.

Due to the improved living standards and the expectation on higher-quality housing of tenements, complaints on the defects in the buildings are increasing every year. Also, the types of flaws are changing. We surveyed one hundred buildings(9,748 households) in 12 complexes across the country to investigate the shifted types. The number of defects received increased by about 1.6 times compared to 10 years ago, while the categories did not change. The report on the malfunctioning mechanical equipment has increased 1.4 times than ten years ago, and the types of the problem changed. The proportion of general parts(water supplement, drainage, water pressure) has decreased about 25% compared to 10 years ago. This is because the items related to the indoor environment become standardized in apartment housing. Therefore the problems related to those have been increased. As the specialized items applied to the tenement building are showing gradual expansion, the defect reports concerning those will also grow.

Since the late 1990s, mixed-use apartment, armed with high qualities and large scales with a high ratio of TFA(Total Floor Area) have been continuously provided accommodating exclusive community facilities along with high-tech securities, not to mention excellent skyline view. However, especially in mid-small cities, there have been only a few supplies. As a result, none of the mixed-use housing provided by high-end brands has ever been built in non-metropolitan area. But constructors couldn't plan the projects which aims to build the mixed-use apartment in local city, because they couldn't get the basic data or advanced research for feasibility analysis. Therefore, to suggest the useful price for mixed-use apartment supply project of local city, the PSM(Price Sensitivity Method) widely used for determining the price preferences as a market research tools has been applied. As analysis results, the estimated price of mixed-use apartment is 10.8% higher than general apartment, and mixed-use apartment has lower price sensitivity than general apartment. As price determinants, the age, education level and family size influence on UTP in significant level. It is expected that these research findings can be applied for establishing the solid marketing strategy of mixed-use apartment development project in local city.

This research was aimed at finding clues of improving residential quality of the Urbanistic Housing which was introduced for the small household of 1-2 residents. It was the communal amenities in multi-family housing complexes that this research concentrated on. Therefore 20 Urbanistic Housing complexes and 11 regular multi-family housing complexes were chosen as the subjects, and all of them were constructed in same period of date and composed of similar number of household units. Compared varieties and design programs of the communal amenities in Urbanistic Housing complexes to those in regular multi-family housing complexes, there were noticeable differences that far less various communal amenities and bland layouts in Urbanistic Housing complexes than in regular multi-family housing complexes. To become a quality residence, it is necessary that Urbanistic Housing are also required to provide certain level of communal amenities, not as much as regular housing for regular household but much more than Quasi-housing, the minimum residence. And it should be ensured by the legal system to make it more practical.

Modular house is built by assembling various joints. Module assembly in the stage of on-site installation is very important process, because assembly process directly affects the structural stability and the quality. However, manual tools and electric-powered tools have a problem in that assembly productivity and quality are reduced during long-time usage. Although pneumatic assembly tools for modular house have been developed, but empirical analysis to compare and evaluate the performance of tools has not been sufficient. This study compares and analyzes the assembly quality and productivity by applying existing assembly tools and new pneumatic tools to the field. The analysis results show that pneumatic assembly tools are more excellent in terms of assembly productivity and quality.
