Purpose: The objective of this research is to investigate and analyze the relationship between physical residential conditions and occupants' responses in apartment buildings by POE(Post-Occupancy Evaluation). The analysis results from this research will help to identify the indoor residential problems and find design solutions for improving overall residential indoor residential environment. Method: The occupant survey was conducted at four different apartment complex area at Cheongju City, Chungbuk Province, Korea. Combination of unbalanced indoor environmental conditions in residential building had difference of occupants' responses according to occupants' characteristics, such as gender, age, and so on. The survey collected data regarding the occupants' EQ(Environmental Quality) priorities to determine the weight of each environmental-quality factor (lighting, acoustic, thermal and indoor air quality). A paired comparison method was used to determine the weight by comparing the relative importance of the two factors based on occupant's survey response. Result: The output from this research is useful to understand the residential environment, occupants' satisfaction, preference, and identifies the current residential problems and finds an architectural solution in apartment buildings.

The ship working environment of combat service support boat is much inferior to the ground working environment. For this reason, the crew of a combat service support boat suffer from an occupational disease such as hardness of hearing. Owing to its small size and low status, the improvement of its working and residential environment was occasionally ignored and its indoor noise was not fully investigated. In this study, for improving its residential environment indoor, the indoor noise of its shipboard compartments was analysed. These studies define the indoor noise level of combat service support boat is very high and some of indoor noise is exceeded the criteria for ship noise. Compared with marine police vessels, the indoor noise levels of marine police vessels are higher than the level of combat service support boat.

Residential Buildings should provide high-quality, comfortable environments to support the activities of their occupants. The indoor environment of residential buildings, which includes thermal, lighting, acoustic, and indoor air quality, has a significant impact on health and quality of life. The comfortable living environment in residential buildings result from appropriately combining these environmental quality factors, and the performance of building systems must be compatible with the activities of the occupants. The objective of this research is to investigate and analyze the relationship between physical environmental conditions and occupant responses for improving environmental quality (EQ) in apartment buildings with four different building orientations (i.e. E, W, S, N) in two different seasons (i.e. winter and summer). The occupant survey was conducted in actual apartment buildings. The Physical environmental conditions in apartment buildings differed substantially depending on space, outdoor weather conditions and building orientations. Each space within the same apartment building had different environmental conditions. Combinations of unbalanced physical environmental conditions in apartment building decrease occupants' satisfactions and their perceptions of overall residential quality. Occupants' satisfaction and their responses to physical characteristics of their residential environment is related to thermal, lighting, acoustic, and indoor air conditions in their buildings. The result from this research will help designers and researchers to identify problems and develop solutions for improving environmental quality from the occupants' point of view.

The aim of this study was to evaluate the influence of air pollution level in industrial and residential district of Ulsan on resident's evaluation and cognition for indoor environment. The evaluation of air pollution materials (as $SO_2$, $NO_2$, $O_3$, CO, PM10) were investigated to understand the distributional characteristics in survey area, and air quality monitoring data from 2007 to 2009 were used. The data was applied in a realtime measurement of industrial and residential area respected to difference of the pollution level in Ulsan. The questionnaire of this survey for resident's cognition was to find out characteristics on perception of indoor environment and outdoor air quality recognition based on the distinct characteristics of the areas. The results of this study shows that resident's satisfaction at clean level outdoor air and indoor environment were different whether it was residential area or industrial area and outdoor air pollution level has direct influence on resident's satisfaction in indoor environment.

The purpose of this study was to develop a measurement model for evaluation of residential environment in low-income families. Residential environment means the housing unit itself and neighborhoods and community characteristics. Based on the previous research on housing environment, six factors (comfortable environment in indoor and outdoor, facilities environment in complex and community, sociopsychological environment, management and economic environment) were selected to evaluate residential environment and to provided a foundation for exploring the multidimensional factors of this research. As s confirmatory study, an Analysis of Linear Structural Relationships(LISREL) was utilized to develop the model. Despite of some measurement errors, the goodness of fit of an overall model was acceptable. Facilities environment in complex and sociopsychological environment were the most important factors in residential environmental evaluation of the low income families. the findings showed that housing policies and programs to improve the quality of homes in low-income families seemed to be beneficial to improve residential satisfaction of the residents.

The Korean Green Building Certification System was activated from 2005. The purpose of it is to improve the quality of residential unit. Recently, people stay inside of building more than for 90% of a day Accordingly, it is really important for them to make the quality of Indoor Environmental better, in brief, to develop the indoor environmental factor in KGBC is important. One of the best way to develop the system is to do research based on POE because the area of problem can be realized. Accordingly, we get the information about POE from another research for the part of the indoor environment for residential unit to have the critical mind about the KGBC, and tried to compare the factors to another which is from foreign Green Building Certification System such as LEED, BREEAM, GBTool, After they have been analyzed, we could find that some of factor need to be revised and added. Also, there was one problem that many part of factor was created without any consideration of direction of each space in residential unit.
