The purpose of this study is to analyze the impact of earthquake on apartment prices. Many studies have been done analyzing the relationship between natural hazards and residential property prices. Most studies have shown that natural hazards have an negative effect on residential property prices, but some studies have shown that natural hazards have an positive effect on residential property prices. These conflicting analysis result from the lack of considering natural hazard frequency at the analysis site. According to literature reviews risk avoidance tendency are already inherent in prices, thus distorting the relationship between natural hazards and prices. That is, in order to analyze the impact of natural hazards on residential property prices, analysis must be carried out in areas where there has not suffered natural hazard for a long time or where there has been no damage before. Nevertheless, previous studies analyzed areas frequently affected by natural hazards. Gyeongju has been recognized as a safe area from earthquake in the past, an 5.8 magnitude earthquake occurred in September 2016. Analysis results focusing on Gyeongju Earthquake case has shown that the earthquake has affected decrease of apartment prices in hazardous areas, and after earthquake apartment prices have risen over time.

This study aims to analyze the current status and characteristics of apartment house unit plans towards spatial differentiation. The 172 house units from 32 housing complexes were selected for this analysis. In this study, factors of residential space plan especially in an apartment house are categorized into general characteristics on floor plan and factors for spatial floor plan. The Primary findings are as follows: (1) General characteristics on floor plan are analyzed based on space organization, area and number of bays. Among apartment houses over 40 pyeong, it seems that differentiation is well applied with various space plans available. (2) A result of an analysis on the factors for spatial floor plan shows that planning a living room with two-open-sides seems to be more common in the tower-shaped apartment blocks which are now on the increase. Moreover, many of them are adopting movable partitions to reflect resident's various demands on space plan. Among all, the extra kitchen in the balcony is planned high portion of 80.4%. And diningroom is positioned on the front side of the residential space along with a livingroom(19.2%). More frequently, dining area tends to face the living room(30.2%) according to the result.

Through the questionnaire survey, residential satisfactions and maintenance consciousness were investigated. As the result of statistic analysis, the residents' needs for improvement according to the life span of apartment communities were found out. And we can also compare the differences about maintenance consciousness to the life span of apartment. The major research findings are as follows. First, the satisfaction averages according to the life span of apartment communities were classified two groups, less than 10 years' and over than 10 years'. By the requirement for improvement according as the life span apartment communities, habitability factors was demanded in less tham 10 years' group and safety factors was required in over than 10 years' group, Second, dwellers have high preference about remodeling to reconstruction. Especially we have to pay attention to the result that positive consciousness of remodeling and long term reparative marked highly in the group which has the short elapsed years. These results represent the possibility gradual step-by-step remodeling. In other words, the object of remodeling is not only odeteriorated apartments but also new apartments to have short elapsed years.

The purpose of this study is to classify defects of the residential building by analyzing the defect specified by prequalification of residential building reconstruction and to suggest the solution of the problem which can be arisen during each stage of plan, construction and maintenance. By sorting the main defects which is specified by pre-qualification of residential building reconstruction for three years from August 2006 to August 2009 into 4 catagories and analyzing the cause of the defects, we draw the way of maintenance to prevent the defects and make pleasant residential environment. The reason for the frequent defects from residential building is mainly deterioration. It occured on the finishing more than on the structure, which means that residents can find defects easier on the finishing than the structure and clear the demand for repair. The result of analyzing of pre-qualification of residential building reconstruction is that the defects mostly caused small, masonry constructed and lower apartment. The apartment which is not into legal right for maintenance naturally have more defects than the others. In conclusion, it is necessary to establish a law of obligation duty of the maintenance of small apartment.

This study tried to prove why a low-rise residential block is more vitalized than in a superblock consisted of an apartment housing complex. To do this, two adjacent superblocks in Yeoksam 2-dong were selected as a case study among superblocks of residential area in Gangnam, Seoul. It adopted the concept of 'complexity', 'Osmosis', 'Vitality' and 'Permeability' for evaluation indexes to measure street vitality. As a result, four indexes were clearly higher in low-density residential superblocks than apartment housing complex superblocks. First, the superblocks for apartment housing complexes showed a lower 'complexity' because large-scale parcels for an apartment housing complex reduces a possibility for various land uses. Second, smaller blocks improved "osmosis" compared to larger blocks, and the larger the block, the less likely it is that buildings and streets penetrate activity. Third, as the apartment complex block became larger, the number of accesses decreased. Thus, it did not provide vitality to the streets. Fourth, high permeability was shown in the low-density superblocks, while that of the superblock consisted of apartment housing complexes was very low because the entrance of the complexes entrance is closed to the public. The results of this study demonstrated that an apartment housing complex may hamper street vitality and deteriorate the quality of urban environments.

Apartments with a southern exposure are often thought to have advantages in receiving winter sunlights and summer natural ventilation. However, as due-south-apartments increase recently, the consideration for residential environment for households with no southern exposure is necessary. In case of due-south-apartments, residents prefer east-sided apartments than west facing apartments which might receive more hot sunlight in the afternoon; however in case of west-oriented apartments with active ventilation, the interior area is bright until late afternoon without unpleasant heat and has advantage in light environment aspects. This study aims to compare and analyze merits and demerits of air flow and sunlighted environment of buildings through sunshine duration simulation using CFD simulation ad sunlights about southeast-sided and southwest-sided apartments based on general opinions for apartment directions. As results of the interior natural ventilation analysis, as the average air flow speed in southwest-sided apartments was 1m/s faster than that of southeast-sided, it has effects of lowering sensory temperature of residents in summer, and for sunlighted environment, southwest-sided apartments are advantageous for sunlighted area for duration time inside. As a result of the research, the calculation of physical residential environment of apartment residential space should be reached through integrated evaluation of natural ventilation and sunlighted time from placement and facing direction of the buildings considering characteristics and environment of each apartment, not based on general opinions.

Residential complexes offer a sense of community and convenience, but making closed and privated space have been criticized.Closed urban spaces have issues encouraging residential segregation.large apartment complexes over 1,000 households,the most poular housing type in Korea, seems to make urban space more closed and privated than ever before. Our study puts forward and tests the hypothesis that large apartment complexes with over 1,000 households are linked to residential segregation. First of all, we examined the degree of residential segregation of metropolitan cities in Korea over a nine-year period (2011-2019). The dissimilarity index and the delta index were used for determining the extent of residential segregation. Next, we tested our hypothesis by Spearman's rank correlation analysis. Spearman's rank correlation analysis was performed on the residential segregation index per administrative division ("dong") and the number of large apartment complexes per administrative division ("dong").
