  • This study investigates the effects of OSRVM mounting location and its configurations such as stalk height and housing height on the aerodynamic performance of the passenger car. In order to validate the flow solver, FLUENT which is very well known commercial code, the flow field around an Ahmed Body was analyzed numerically and compared with the experimental data. The predicted aerodynamic performance and flow patterns around a car show good agreements with the experimental data. Mounting location and stalk height should be designed while OSRVM is mounted on the car to evaluate the aerodynamic performance precisely. Housing height, however, may be designed independent of the car because the aerodynamic interference between housing height and car configuration is negligible.

  • In the design guideline about the existing elderly housing, the equipment related to bathroom are the most important in the secure and functional aspect. On the other hand, the present elderly housing is being designed according to foreign design guideline or common housing form instead of reflecting living and physical qualities of the Korean elderly. Therefore, in this study based on the guideline of the existing literature, we made Mockup furnished with the equipments of bathroom and conducted an experiment in finding proper position and height for Korean elderly enough to use the bathroom conveniently and independently. The equipments of bathroom consist of different height wash bowls, toilet stools, grab bars, and a bathtub. As a result, suitable height of wash bowl is 760 mm $\pm{\alpha}$. We can realized that elderly feel comfortable to grab perpendicular bars of toilet stools more than horizontal ones. So it is necessary for elderly to grip perpendicular of grab bars added to prevention slipping and made shape easy to hold. Most of elderly told us that 500 mm of the bathtub setting is suitable. But many other people feel high. So height of the bathtub must be established lower than 500 mm for safety in the bathroom and for convenience.

  • The purpose of this study is to prove the correlations among various factors what determined to formation of front elevation proportion system through making an actual survey and investigating. According to the analysis of them, we make conclusions as follows; 1, On the assumption that average distance of 1Kan(間) is 1, the height of foundation is 0.21, the height of floor from foundation is 0.24, the height of normal column from floor is 0.85, the height of eaves from foundation is 1.10. 2. Southeast faced buildings are wider than southwest faced buildings in the distance of 1Kan (間) in the range of $110{sim}220mm$. The height of foundation and floor in the southeast faced buildings are higher than those in southwest faced buildings beside the height of normal column, eaves, high column in the southwest faced buildings are higher than those in southeast faced buildings. 3. As number of front Kan(間) increases, the distance of 1Kan(間) decrease and the height of eaves and high column(高柱) increases. This is cause of making a maximum needed inner space by increasing the distance of 1Kan(間). This is an wisdom for living from ancestors. 4. As number of Dori(道里) increases, the distances of 1Kan are nearly same but the height of eaves and high column(高柱) increases about 300mm, This is a natural result from an increasing of building scale. 5. The distance of 1Kan(間) in later 19C building is most wide but, the unit heights are minimal average values at year 1900 as a reference mark. After this, the height of normal column, eaves, high column are higher about $170{sim}330mm$. 6. The number of Kan in front elevation, Dori(道里), and direction of building have correlations each other in proportion system of traditional housing An-Chae with significant level, p<0.05.

  • The purpose of this study was to identify the universal design characteristics in residential environments. The subjects were 135 physically disabled persons who lived in the rental multi-family housing apartments in Pusan. Interview method was used for this study. They were an average age of 51 years and 63% were male. They were low income families and lived in 12 pyung ($39.75\textrm{m}^2$) apartments. They were asked about what housing characteristics were constraints in their daily living. They pointed out that the constraints in their apartments were as follows: 1) the small amount of space in the bathroom, kitchen, bedroom, and the entrance area of housing unit, 2) the unflat floor level between the bathroom and the hallway, or the balcony and the bedroom, 3) the slippery floor finish in the bathroom, 4) lack of grab bars or handrails in the bathroom and the ramp, 5) the kitchen work centers and the electric switches at improper height, and 6) the steep ramp. Therefore, the universal design characteristics in residential environments were the adequate amount of space, flat floor level, non-slippery floor finish, grab bars or handrails, accessible height, and ramp.

  • The aim of this study was to analyse the design characteristics of court housing. In spite of changes of housing design condition, especially density, there have been changes only in the height of housing block, not in the housing types, layout system and other design properties. Due to the situation, housing design in Korea has been criticised as too routine and monotonous one. As one of the alternatives to respond to the criticism, this study focused on the positive aspects of the court housing type, and suggested the design strategies throughout the analysis of 8 entries in the design competition of EunPyeong NewTown, which attempted to overcome the negative problems - mainly the daylighting, orientation, and privacy- of this housing type. Throughout the analysis, there suggested design strategies to respond to the problems of court housing type, which can be the basis for the court housing design in Korea.

  • This research progressed space evaluation test with 3D simulation for exterior space of detached housing area among the Seoul spaces of child sex offense in 2010. Based on changing analysis on natural surveillance by spatial changes of each physical element, the purpose is to suggest effective construction planning measure for preventing child sex offense. The results of research are as follows. First, natural surveillance of space's height differences and width differences were compared and analyzed. As the result, footpath shows that stairs of slope didn't make lots of effects on visual block, not block of spatial moving, because of the difference of stair height. Also, in case of parking space, visual connection with footpath is expanded when designing pilotis rather than heightening floor height, so activities of exterior people could be seen more easily. Therefore, natural surveillance was higher. Second, natural surveillance of architectural elements by changes of footpath' width was compared and analyzed. As the result, openness of footpath should be secured rather than openness of architectural element. And, planning autonomy of architectural form could be more expanded when securing openness of footpath.

  • This study compared the recommended levels of illumination for housing. KS Recommended Levels of Illumination (KS A 3011) in Korea, Recommended Levels of Illumination (GB 50034-2004) in China and Recommended Levels of Illumination (JIS Z 9110) in Japan are compared. The results are as below. First, recommended levels of illumination used in Korea China Japan are suggested by different locations and activities. However, classification for application scope is set differently. There are 10 areas for classification used in Korea, 5 areas in China, and 13 areas in China. When medium levels for classification are included as classification level, total of 15 areas are used for classification in China. Second, when considering there are 15 areas of application scope in China for recommended levels of illumination, there are 7 areas that are commonly used in Korea China Japan. 7 areas include stadium, factories, hospitals, office, shopping center, houses and hospitals. Third, working surface is considered as the height for recommended levels of illumination in Korea China Japan. Korea and Japan consider all working positions, standing and sitting position, when deciding the height. However, China only considers the standing position. Fourth, application scope for recommended levels of illumination for housing are classified in 16 areas in Korea, 5 in China and 18 in Japan. Thus, the application scope for recommended levels of illumination in housing in Korea is similar to Japan. However, there are only 5 areas used in China such as living room, bedroom, dining room, kitchen and sanitary room. Fifth, recommended levels of illumination is classified in 3 levels such as Lowest-Moderate-Highest while China and Japan only have standard recommended levels of illumination. Sixth, when observing recommended levels of illumination by type of activities, Japan classified the activities in greatest detail followed by Korea and then China. Seventh, Recommended levels of illumination differs by each country.
