Purpose: Condensation in walk-in closets attached to apartment bathroom has been known as an emerging issue that may threat occupants' comfort and health. Despite a number of design guidelines and enforcements to prevent condensation, condensation issues may still occur depending on various cases and scenarios. We aim to identify what condensation scenarios may lead to walk-in closet condensation and/or worse the existing condensation issues. Method: First we choose an actual walk-in closet of an apartment that suffers from sporadic condensation and resulting mold and mildew. Then we observe its relative humidity and temperature after the bathroom is used, in which excessive vapor is thought to be transported to the walk-in closet. We analyze Temperature Difference Ratio - a domestic indicator of condensation occurrence, and dew point temperature to compare it with surface temperature using 2D heat transfer simulation upon various condensation scenarios. Result: TDR of the test walk-in closet turns out be OK despite mold and mildew actually occurring. Hot water pipe installed in the floor would greatly reduce condensation. If hot water pipe in the upper floor, however, is not used, or hot water pipe of the closet is turned off during swing seasons, it is expected that condensations may still occur.

The purpose of this study is to provide a basic for a desirable bathroom plan of apartments. As a first step in this process, we analyzed the bathroom plans of the apartments(area: 10-69 pyung) constructed in 8 sections in Seoul from 1971 to 1995 where 65,801 households live. In this study, the numbers, location, size, and proportion of the bathroom and dressing room, and the direction of the bathroom door in apartments are examined. The major frindings are as follows; 1) We have found that the numbers of bathrooms to increase in more than 20s pyung apartment since 1990. 2) Except a master bathroom, the another one for the guest is located in enterance in more than 40s pyung apartment. 3) The door of the bathroom faces corridor in more than 40s pyung apartment. So, it is possible for them to lessen discomfortness when they coming in and out of the bathroom. 4) It was found that the size of bathroom were decreased in most cases. 5) They did not plan a dressing room in 10s pyung - 60s pyung and the size of dressing room was decreased in 60s pyung apartment.

This study examines the furniture usage behavior of the apartment dwellers in tile city of furniture usage by resident’s characteristics, such as floor space size, household income, the stage of family life cycle and housewife’s age. To this end, interviews were conducted with 304 individuals, either household heads or their spouses living in three residential areas in Seoul. The sample was selected among people living in apartment units with the 30s and 40s pyong of floor space size.The major findings of this study are as fllows ; The furniture and furnishings selected for the study are grouped into four clusters such as conversation-space components, ordinary decoration, high-quality decoration and miscellaneous components. Families in the stage of primary school life cycle were likely to possess fewer furniture and decorations than those in the stage of high school life cycle and in the launching stage. Younger housewives are less likely to possess ordinary and high-quality decorations than the older. Those living in the larger apartment units are likely to decorate their living room in an ornamental rather than functional way, and to possess more ordinary and high-quality decorations than those in the smaller. In this study, the size of floor space appers a variable most powerful to explain the pattern of furniture usage.

This study aims to identify the change of bathroom design characteristics through the investigation of bathroom space in apartment model houses. The bathroom space of each private exclusive area was analyzed from the plane characteristics perspective such as quantity, location, size and shape. For this study, site survey and observation was performed to analyze the characteristics of plane and design based on twenty seven model houses of seven large-sized construction firms with Seoul area focused on. Research object was restricted to from ten Pyeong's apartment to sixty Pyeong's in order to understand various characteristics of twenty seven model houses. Since analysis variables were not diverse, the main three factors - frequency, percentage and an average - were represented in Microsoft Excel worksheet, focusing on the quantity of each case, design characteristics and pattern. 1) The quantity of bathrooms: It was turned out that the quantity of bathroom was one in ten Pyeong's apartment while it was two in thirty, forty, and fifty Pyeong's apartment. There were mostly two bathrooms available in twenty Pyeong's apartment even if only one was planned in few cases. All powder rooms and dress rooms in twenty and fifty Pyeong's apartment were designed to be separated and be accessible through bedroom. 2) The size of bathrooms: As private exclusive area increased, the size of bathroom for both family and couple increased. Couple bathrooms had the tendency to be equipped with shower booth and bathtub at the same place or have more tubs than family bathrooms because couple bathrooms were bigger than family bathrooms. 3) The location of bathrooms: Couple bathrooms were usually located beyond dress rooms or powder rooms while family bathrooms were mostly located at the entrance side. 4) The shape of bathrooms: Shower booth was assumed to be in general vogue because family bathrooms, for the most part, were comprised of a flush toilet, a washstand and a shower booth. In the case of couple bathrooms, a flush toilet, a washstand, a shower booth and a tub were generally equipped in more than twenty Pyeong's apartments while a tub was not installed in twenty Pyeong's apartments.

The road traffic noise has been increasing broader effects on urban areas as well as rural areas because of rapidly increasing traffic volume and newly-constructed roads. 10 sites in building development areas were selected and the noise levels were measured by the apartment floors and by the various block plans of apartment complex. The results showed that the highest traffic noise level was obtained at the 5 and 7 floors on the apartment floors. On the basis of 7 floor with the highest level, the correction coefficient obtained from noise reduction by each floor and measurement point was -5.54 dB(A)(1st floors), -0.96 dB(A)(3rd floors), -0.38 dB(A)(5th floors), 0.00 dB(A)(7th floors), -1.98 dB(A)(l0th floors), -3.10 dB(A)(13th floors), -3.45 dB(A)(15th floors). The level of road traffic noise in the arrangement construction of right angle was about 3.0 dB(A) at N-4 point and 2.1 dB(A) at N-6 point lower than that of a plan figure, respectively. The results suggested that application of correction coefficient obtained by the apartment floor and by the arrangement construction can be improved in road traffic noise.

As the increase in quantity of apartments has been stable, consumers' needs in housing quality become more diverse. According to the changes in the tendency of residents, construction companies has developed brands of apartment buildings with the concepts of LOHAS, well-being, ergonomics, ubiquitous. However, these trends has been focusing on the Capital area, and becoming fixed and typical in the way of delux quality, large-sized houses and a healthful residence. For that reason, this research is about survey on the needs of the local apartment residents, especially in Daegu. This analysis of their preferences will furnish basic data and offer possible interior plans to building companies making inroads into the Daegu apartment market. This research is based on the questionnaire forms which had been collected for two months(in Aug.-Oct.) of 2005 in Daegu and the amount of the samples is 135. All of them are the residents of the apartments where they moved in after 2000. The contents of this research include the evaluation of plane composition and practicality, interior finishing and design, and spaces for items. The results of this research show that the interior design and finishing materials of apartments in Daegu should be improved and the drainage and uncleanness of bathroom also need to be considered, much like the results of Seoul area. However, regarding the higher age range and life stage, the bedroom 2 needs to be planned for a study and the design of livingroom is prefered to be widely open. Besides, comparing with those in Seoul, the residents in Daegu demand that spaces for things (especially those in secondary kitchen and dress room) be more organized and convenient.

The main factors that made Seoul's rapid population accommodation and urbanization possible in the mid-to-late 20th century were the ex-pansion of urban infrastructure, completion of the transportation system, and housing supply. The development of transportation and resi-dential development occurred simultaneously, and in particular, apartment complexes, a representative residential area in Seoul, were most influenced by Perry's neighborhood unit theory. The purpose of this study is to analyze the process of the physical environment of apartment complexes in the metropolitan area in response to development of transportation in the mid-to-late 20th century. The analysis sites are Jamsil Apartment Complex(1974), Dunchon Apartment Complex(1979), Mok-dong New Town(1983), Sanggye New Town(1985), Bundang New-town(1990) and Ilsan Newtown(1990), which were planned at the turning point of development of transportation and actively reflect the neigh-borhood unit theory. The analysis was conducted in three stages. Analyzing the status of transportation when the plan was established, deriv-ing the planning elements, and classifying the planning elements into walking, bus, car, and subway which is the representative transportation. The conclusions from the analysis are as follows. Firstly, completing the legal system and expanding the related infrastructure are essential. Secondly, in contrast to the increase in traffic volume, the pedestrian environment has been continuously improved. Thirdly, despite the emergence of new mode of transportation, there was a tendency to activate the linkage between transportation.
