This study was carried out to examine the effect of the presence of non-structural walls in apartment buildings subjected to an earthquake. It was believed that the presence of non-structural walls, which has not been considered in the structural design process, was usually built together with structural walls and this led to significant damages to the apartment buildings in Pohang earthquake, 2017. In this study, a 22-story apartment building was selected and modeled to simulate the seismic behavior due to earthquakes. The story drift, performance point, and compressive strain in the walls were the main parameters to evaluate the seismic performance with the presence of non-structural walls.

The procedures of safety diagnosis assessment have been applied by synthetical consideration of structural safety, functionality, and economic efficiency in determining reconstruction or remodeling, but they have limitations in some special cases such as the non-association apartment. In this regard, this study was conducted to establish more desirable criteria and procedures in determining reconstruction or new construction and suggests a way to improve policy and laws of reconstruction correctly by reviewing the safety diagnosis in reconstruction process. Besides, the safety diagnosis of reconstruction for non-association apartments in government-owned public district was carried out preemptively to remove reckless procedures. As a result, the reconstruction of non-association apartments should be effectively without interference in the administrative procedures. This requires that the policy and laws of reconstruction safety diagnosis should be revised in priority in order that similar projects in future can be effectively executed.

The goal of this study is to identify the sense of community that is present in people based on different housing types and to devise methods for a sustainable community by comparing and contrasting the factors affecting the sense of community between apartment residents and non-apartment residents. The data for the analysis was collected using the questionnaire survey method from July 23~30, 2015, and the sample consisted of 225 respondents living in Gongdukdong, Mapo-gu, in Seoul. The results were as follows: (1) The attitude and sense of community in both groups turned out to be near the middle range without showing a significant difference. (2) All the variables related to the attitude towards the community that have impacts on the development of sense of community show significant positive correlations in both groups. (3) Determining factors of the sense of community are -in the order of importance- frequency of interaction, community awareness, and satisfaction level of community facilities. This result indicates that developing customized programs to enhance community interactions and making people aware of policies and support available are more effective in building a strong sense of community than expanding and refurbishing community facilities.

This study introduces a newly developed PC non-bearing wall system to prevent the damage of RC wall-type apartments that have been heavily damaged by the 2017 Pohang Earthquake. In order to evaluate the performance of the developed PC non-bearing wall system, a static cyclic test is conducted. The prototype of test specimen is from the RC wall-type apartment which has been severely damaged by the 2017 Pohang Earthquake. The specimen with the conventional non-bearing wall system showed the similar damage of RC wall type apartment suffered from the Pohang Earthquake. In case of the specimen with the developed PC non-bearing wall system, cracks and damages were not transmitted between the walls due to the seismic slit and there were almost no cracks in the non-bearing walls. Therefore, the proposed non-bearing wall system, separated from the structural walls, could prevent spreading cracks to bearing walls and make it possible to effectively control damage due to earthquake loads.

The purpose of this research is to demonstrate the necessity of conserving and maintaining eco-parks by estimating their economic value. Wonheung-ee Park in Sannam 3 District of Cheongju City was chosen as the subject and a quantitative estimation was conducted. The quantitative analysis utilized the hedonic price model that estimates the value of non-market goods. The summarized results of this study are follows. The subject park influenced the prices of its neighboring apartments. The most important factor was the distance between the park and the subject apartment. When the distance was longer than 400m, the impact was greatest. The quantitative assessment also showed that apartment prices and the distance between an apartment and the park had a negative relationship. When the distance increased by 1%, apartment prices decreased by 0.430%. This means that within a certain distance, the closer an apartment is to the park, the higher is the price. Demonstrating the economic value of eco-parks, this study also supports the importance of preserving eco-areas. It generally shows that when we develop a city, we should refrain destroying the ecosystem.

The present study is a preliminary research improving the dwelling quality of apartment house as a kind of multi-family housing. The purpose of the study is to find out the actual state on characteristics of indoor noise including residents' living in apartment units. The method was field survey consisted of field measurements on equivalent noise level, observation on noise type, and interview on residents' responses. Field survey were carried out in 20 occupied apartment units from January to March 2007. The results are as follows. 1) Averages of indoor noise levels including residents' living noise were measured as $43.9{\sim}62.2\;dB(A)_{Leq5min}$, the average of each house except one was higher than the permissible level, 45 dB(A). 2) The noise types observed were mostly residents' living noise and classified into 'water hammer', 'living equipment noise', 'noise by family', 'hood noise', 'kitchen noise' in own unit, 'walking and talking noise in stairs and corridors', 'noise by neighborhood house', 'noise by the upper story' in building, and outdoor noise. 3) The residents showed slightly non-positive responses at 'noise by the upper story', 'noise by neighborhood house', 'water hammer', and 'noise by family'. Therefore, it is required to plan for preventing deterioration of the dwelling quality by residents' living noise in own unit as well as by neighborhood houses.

Apartment design in residential Area is restricted by building distance limit code. Building distance limit decreases gradually to the 0.8H(height), and residential area has 250% site area ratio by building code, so site using has become efficient. In this study, examine the relationship between present building distance limit and right of daylighting environment by computer simulation. As well, high-rise residential officetel and multipurpose residential building becomes increase in commercial non-residential area. In the domestic, residential type multipurpose building made at the business area or central business area has 400∼800% site area ratio by building code. However, at a dweller's point of view, there are much lacks of environmental consideration to provide suitable daylighting environment. And, POE: Post Occupancy Evaluation is not completed yet. In this study, however, progress architectural environment prediction, basis by right of daylighting, and examine the possibility of daylighting by architectural distance limit code in residental area and by high-rise, high-density residential building in non-residental downtown area.
