Korean society expects to be changing into aged society more rapidly than any other countries due to low birthrate and increase in life expectancy. Increasing number of elderly and social problems of aging society have provoked increase in research on elderly environment. Elderly housing facilities and living conditions are significantly related to the quality of life for older persons. The purpose of this study is to systematically analyze empirical studies on elderly physical environments in Korea, find out research streaming and understand social backgrounds and to suggest future research problems. For this study, contents analysis was conducted. Articles of four academic peer reviewed journals published from 1986 to 2005 were units of analysis. Using a keyword through library database systems, the articles were systematically selected. As results, trends of research according to 4 periods were defined. Among them as major trends, expansion of the quantity, expansion to interior design features for older persons, more facility types for dependent elderly(assisted living facilities, facilities for elderly with dementia, long term care facilities) have appeared. This result showed some directions and implications on elderly facility planning and development.

This study is a preliminary investigation into improving the environmental quality of schools. The purpose was to clarify the present conditions and reasons of noise in elementary schools located near airports and roads by noise level measurements and questionnaire surveys of subjective responses. fold measurements on equivalent and instantaneous noise levels, indoor and outdoor, were carried out in 3 schools during the periods 11th~ 13th of February and 2nd~ 7th of July,2003. The respondents were 94 teachers working in the 3 schools. The results were as follows. 1) Indoor noise levels of the 3 schools were 36.g~73 dB(A) in winter, and 46.9~ 91 dB(A) in summer. These values were higher than the indoor noise standard of 50 dB(A), except for the average of equivalent noise levels in winter.2) Outdoor noise levels of the schools were 41.1 ~ 101 dB(A) in winter, and 52.4~ 102 dB(A) in summer. These values were generally inappropriate relative to the standard for environmental noise of 65 dB(A). 3) The respondents showed relatively non- positive responses during school hours for interruptions by environmental noise.4) The frequently checked types of environmental noise of the schools were 'airplane noise','surrounding facilities', and 'traffic noise'. The frequently checked types of damage by environmental noise were 'Interrupting school hours' and 'Interrupting business'.

Understanding consumers' latent desires for product form has now become a critical issue in product design. Accordingly, product development processes is rapidly changing from product-oriented development to user-centered development. Driver visibility is considered as an important element of driving posture packaging in automobile interior design. This study presents a systematic process for driver visibility analysis approached from affective engineering method that provides design variable selection and screening with respect to the image/impression element of the human visibility. Also, the analysis of front visibility, often called the feeling of "openness", in motor vehicle interior design, is selected and practiced a case study using the systematic process proposed in this study. Twenty six participants evaluated the feeling of openness for thirty motor vehicles following the perceived scale of affective design factors. The results showed that variables such as the height of head lining, the height of cluster housing, the gradient of windshield and the volume of A-pillar were the critical design variables which affect the feeling of openness in a motor vehicle.

An attempt is made to illuminate the characteristics of Korean high-rise apartment plans built after the 1990s in Seoul. Unlike the typical slab block plans of the past century, these plans were accommodated in a super-highrise building which normally integrates some portion of commercial areas on the lower floors. Thus, they are much different from the pre-1990s plans, so needs to have different strategy to adapt to the Korean dwellers' domestic requirements. This study reveals the topological patterns that appear in these new plans, and tries to relate these patterns to the old configuration patterns of the slab-type apartment houses. From the analysis, it was found that some important Korean dwellers' characteristics are still preserved, but at the same time, some unprecedented patterns were beginning to be absorbed into the spatial arrangement. At the end, suggestions are made on how this emerging trend of super-high rise can be better understood and evolved to enhance the living quality in a new multi-unit setting.

Various residential patterns, which can accommodate ever-changing modem lifestyles, are increasingly needed. On the residents' demand for flexible space, mote research should be conducted on the apartments built by the concept of flexible space. In this study, apartments of 40-60 pyeong in size built in the region of Seoul, between 1998 and 2007, are analyzed in terms of the flexible types and the unit plan composition. To reflect the changes in people's perception of residential quality-preference for a residence with a good view, over for the direction that a residence faces, more rooms are placed on the front bay. From the analyses of this study, flexible unit plans are classified into 6 types; and it was found that, as the size of apartments gets larger, the livingroom and the dinning room tend to be placed on the front bay. After grouping rooms with a similar function into the spatial zones of the master bedroom, children's room, the livingroom, and the dinning room, flexible types are analyzed in terms of the location of rooms. The results of this study will be able to contribute to establishing flexible housing culture that can accommodate the changing needs of residents.
