  • Korean architecture classifies Banja (the decorated flat of the ceiling visible from the inside) of Royal Palaces into two types: Woomul(water-well, 井) banja, which inserts rectangular wooden board into lattice frame, and paper banja, which applies paper to the flat ceiling. Such classification was established in the 19th century. Before that, Banja was classified according to what was inserted into the lattice frame, either wooden or paper board. At first, the banja that used paper board was widely installed regardless of the purpose or nobility of the building. However, since the 17th century, the use of paper board banja became mostly restricted to Ondol (Korean floor heating system) rooms which are characterized by private usage and the importance of heating, and it was considered inferior to wooden board banja in terms of rank or grace. The contemporary paper banja was mainly installed in low-rank ondol rooms until the late 19th century to early 20th century, when roll-type wallpaper was introduced from the West and the paper banja came to decorate the King's and Queen's bedrooms. The traditional paper board banja benefits heat reservation, reduces the weight of the ceiling, and allows the adjustment of the lattice frame size. Furthermore, it can feature unique artistry if covered with blue, white, or red Neung-hwa-ji (traditional flower pattered paper).

  • For those with disabilities, the residential area is the primary place to adapt the disabilities. Since the quality of the area gives a critical impact on their quality of life, it is essential to finding the measures to create the residential environment that supports their independence. In this regard, this study aimed to compare and analyze the interior elements of the houses that hinder the independence of the physically handicapped in the rural and urban areas, and conducted a survey on a total of 80 physically challenged in Seoul and Yeongwol (40 for each area). As a result, the respondents answered that the houses where they are currently living are hindering their independence regardless of area, and there were regional differences in the level of inconvenience with the size of living room, size of utility room, location of room, lighting and heating environment, ventilation system, deteriorated wallpapers and finishing materials, threshold and floor level difference and humidity control. This study has significance by providing the realistic measures to improve the housing environment of the physically challenged living in the rural and urban areas to be customized to them to increase their quality of life.

  • It is possible to explain the design, the meaning, and the use of domestic space by comparing different cultures. The characteristics of Koreans' housing life living in western cultures has already been studied extensively. Because of political reasons, however, the characteristics of Koreans' housing life living in Chinese culture has hardly been studied at all. The purpose of this study was to find out the characteristics of succession and transformation of domestic housing culture. The data was collected by questionnaire methods from fifty Korean households and eleven Chinese households. Individual interviews and actual surveys, including taking pictures were also used for data collection. The results of this study were as follows (1)An analysis of heating system usage behaviors showed the importance of heated floors, known as Ondol, is one of the enduring characteristics of domestic habits. (2)In the sitting style, the traditional sitting on the floor was shown in living room. (3)Regarding room usage behavior, Korean households were centered around the living room in chinese houses. (4)An analysis of space organization preferences with respect to common spaces revealed that Korean households tend to prefer the open plan of common spaces.

  • To investigate the actual conditions on the living environment of group-homes for the elderly and their living environment, 4 group-homes were surveyed. As the results, conditions of location for the group-home of the elderly looked positive, on the other hand, safety for criminal prevention, accessability and convenient facilities were not on level satisfied. The average area of each space in the group-home indicated that the bed room was $11.21\;m^2$, the living room $28.13\;m^2$, the kitchen $23.59\;m^2$, and the bath room had an integrated type of bath room and toilet $7.63\;m^2$. The physical environments of each space in the group-home were investigated, In bed room, door, windows and illumination were relatively good but safety was extremely inferior. Living room mostly looked good except the doorsill which needs refurbishment. In kitchen, cooking table, windows, illumination, ventilator were somewhat satisfactory but gas-warning device should have been installed. In addition, in bath room and toilet, location, door, window, illumination and finished material were satisfactory. But the stepped difference between the bath room and other space, safety-bar, emergency bell and floor heating system were seriously deteriorated and must be improved for the safety of the elderly. Conclusively, living environment of group-home for the elderly is mainly satisfactory but it was necessary to take a consideration for their safety.

  • 에너지절감에 대한 인식이 높아짐에 따라 점차 건물이 밀폐화되고 있으며, 이로 인하여 실내공기질에 영향을 미치는 건축자재로부터의 휘발성유기화합물 방출에 대한 관심이 높아지고 있다. 그러므로 실내공기질을 개선하는데 있어 건축자재로부터의 VOCs 방출특성을 파악하는 것이 무엇보다 중요하다. 본 연구에서는 우리나라가 온돌문화인 점을 고려하여 대표적인 건축자재인 온돌마루와 접착제를 대상으로, 방출챔버시험을 통하여 온도 및 시간경과에 따른 헥산, 톨루엔 및 TVOCs 방출특성을 살펴보았다. VOCs의 방출속도는 온도와 비례관계를 나타내었으며, 바닥재에 존재하는 VOCs 발생원이 어느 위치에, 어떠한 형태로 존재하느냐가 시간의 경과에 따른 방출특성에 크게 영향을 미친다는 것을 알 수 있었다. 즉, 건축자재로부터의 헥산, 톨루엔의 방출은 전반적으로 초기에 방출속도가 높고 시간이 지남에 따라 점차 줄어드는 경향을 보이고 있으나, 온돌마루로부터의 톨루엔 방출은 다른 양상을 보이는데 시간이 지남에 따라 방출속도가 오히려 증가하여 6시간 경과 후 최대값을 보인 뒤 점차 감소하는 경향을 나타내었다. 이는 온돌마루에 함유되어 있는 톨루엔 발생원이 자재의 내부에 많이 존재하고 있기 때문에 시간이 경과함에 따라 방출속도가 증가했다가 다시 감소하는 경향을 보인 것으로 추정된다. 바닥재로부터의 VOCs 방출특성 실험결과를 종합하여 살펴보면, 온돌시스템에서 방출되는 고농도의 VOCs에 인체노출을 줄이기 위해서는 이사하기 전에 적어도 72시간 이상의 Bake-out 시간이 필요할 것이라 사료된다.
