Recently Requirement of indoor environment is increased in APT. Among indoor noises of APT, noise of plumbing system in bathroom is very serious problem except of floor impact noise. Plumbing system with wan hanging unit make a good grade and recognition in rating noise of bathroom in grade of house rating. But it is hard to find a data which are measured in APT built. In this study, the effect of noise reduction is checked by measuring the noise of plumbing system with wall hanging unit that is built. As result the upper household's Peak sound level is measured 80dB(A), the under household's peak sound level is measured 40dB(A).

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 purpose of this study is to analyze the typological characteristics of super high-rise housings in Hong Kong. The results are as follows; 1) Most of the plan types of the residential building in Hong Kong are tower types and they show lots of curves on the external resident blocks so that each resident families can face maximum open air. 2) Each residential unit is arranged symmetrically and systematically around the central core. 3) The most of core types are central core types which are usually planned to place void light well to improve lighting and ventilation. 4) Rooms are arranged in line from entrance to kitchen, to living & dinning room, and finally bedroom and bathroom. Dinning area is arranged together with living area. 5) At least, more than two sides of the each unit were facing the open air; one side is for the view from a bedroom or a livingroom, the other side is for the ventilation of a kitchen or a bathroom.

The purpose of this study was to compare the characteristics of floor plan of $85m^2$-sized housing units with 2-bay and 3-bay and the residents' satisfaction with them. The subjects for analyzing floor plan were six floor plans of $85m^2$-sized housing units with 2-bay and nine floor plans of housing units with 3-bay in the new town, Hwamyeong-dong, in Busan. The floor plans were analyzed based on seven characteristics of floor plans such as the composition type of entrance core hall, the entrance arrangement, width and depth of the housing unit, size of each room, LDK arrangement, arrangement of family bathroom and private bathroom for husband and wife, and balcony arrangement. The subjects for grasping satisfaction with each housing unit were 400 residents of $85m^2$-sized housing units. A half of them lived in housing units with 2-bay and another half of them with 3-bay in the same area. They answered about the degree of satisfaction with the characteristics of each room and the preferred floor plan type if they move to the same size housing units through a questionnaire. The results were as follows; First, the floor plan with 3-bay had more diverse elements than one with 2-bay. Second, the residents who lived in 3-bay housing unit were younger, higher education, and higher income than the ones in 2-bay. Third, the residents who lived in $85m^2$-sized housing unit were more satisfied with and preferred to 3-bay housing units than 2-bay one.

The purpose of this study was to find out the residents' consciousness of the unit plan on condominium apartment and to contribute to develop a condominium apartment unit plan in Daejeon City. This research was performed by a questionnaire survey method, 464 data was collected from apartment residents lived in about $85\;m^2$ unit with 3 rooms and the apartments was limited to the complexes within 1-4 years of the length of building at Yuseong-gu and Seo-gu. By analyzing those data, findings are as follows: 1) Residents thought living room, kitchen and bathroom were importment space in a unit plan. They needed a storage function in an entrance and a intermediate room, and Anbang(mater bedroom) so did. 2) L-DK plan type was very popular and the type of front DK with L on the floor plan was preferred. This was unique results. 3) Sub-kitchen was needed for a refrigerator of Kimchi, the location of it was related to a main kitchen and a utility. the third room was needed for library, home office and storage space. 3) Bath-tub in An-bang and showe-booth in public bathroom was preferred. This was same to the popular trend of Korean condominium apartment. 4) The enlargment remodeling of balcony was showed livingroom balcony or personal bedrooms at the time of occupancy.

The purpose of this study is to find out the changes on the metropolitan condominium apartment unit plans based on the interior spaces related to women such An-bang (master bedroom), bathroom and attached spaces to the master bedroom, living room, diningroom, kitchen, utility room, and balcony. This study used the content analysis method and space syntax. Contents were limited to the floor plans with 3 rooms type and about 105 m2 in the Korean apartment encyclopedia. The unit plans of 2,278, built from October 1975 to January 2008, were analyzed and basically SPSS package 16.0 was employed. The results were as followed. 1) Living room was a core space and an increasing tendency. After 2001, the design trend of living room connected with kitchen and dining room, and dining room changed into one space combining with women's working space such kitchen. It meaned women's working activities became into family public activities as to depending open access. 2) Kitchen had a characteristics that was connected to utility room or back balcony, and the number of extra kitchen increased. Also, the size of DK decreased, but utility size little increased. It was showed the characteristic of this space was still for women. 3) An-bang had a little strong characteristics of married coulpe or women's personal space with bathroom or dress room/powder room. 4) In addition, the values of integration and control of living room and DK were highest. It meant these space were centered in unit plans. Next, the An-bang and dress room/powder room were high. Utility room or balcony's were next, and these were women's working space. Therefore, family's public space was most important, and married couple or women's personal and working space were later in planning.

The purpose of this study is to find out the spatial characteristics of the multi-housing units in Seoul and Kyung-gi area since 2006. Literature review and content analysis were used for this study and 82units of the big size over $165m^2$ were analyzed to review such design characteristics as spatial composition, layout and linkage. Through this study, the following conclusions have been reached; 1) Most unit plans had 4LDK and 3bath types including family room as a public space. This results shows that family-room and bathroom has recently become more important than number of rooms in multi-housing units planning. 2) Diversity of plan figures such as mass-mixing, mass-separation and polygons(L, V-type)was showed in most unit plan, breaking from the standardized forms of box types. 3) Intermediated spaces such as foyers and halls in entrance zone were planned and sub-entrance into kitchen were planned for the various types of circulation and work-efficiency. Cases had private space separated from public space, the dispersion of rooms with the increase of connection by corridors, L-DK meaning the living room isolated from the dining and kitchen, partially located living room for a view in area distribution. The spatial planning of master-zone mostly consists of the types of two-rooms and an entry into a foyer(library, dress-powder room, bathroom and master bedroom). This study has a significant meaning on grasping current trend in Korean multi-housing and to provide information for future direction on housing-unit design.
