The dominant heating system used in Korean residential apartment buildings is a hydronic radiant floor heating system, known as the Ondol system. The most common control strategy applied to this traditional hydronic radiant system is a simple on-off control that intermittently supplies "hot water of a fixed temperature" at a "constant flow rate" to each room. However, the current problems with the aforementioned control are as follows: (1) since the simple on-off control is usually based on a one point measured temperature (a signal from a thermostat installed in a living room) in each dwelling unit, heating energy use for unoccupied rooms as well as a difference in temperatures between spaces (master bedroom, living room, bedroom1, bedroom2) can occur occasionally. (2) the most widely used residential water splitter has static valves, and is thus not able to change the flow rate to each room depending on the space heating load. In other words, the ratio of flow rates to rooms is fixed after construction, resulting in over- or under-heating and an improper use of energy. The aim of this paper is therefore to investigate the differences in the system's performance between control strategies in terms of the flow rate control and sensor location. It is shown that energy savings of control strategies are strongly influenced by occupant schedule.

The purpose of this research lies in providing basic data for appropriate territorial adjustment within the family by understanding the relation to family members and how 'territorial dislocations' caused by differences in personal space and behavioral domains are used and controlled as living elements. As a result, the following data could be obtained. 1. General usage conditions of living elements. When the order of usage conditions of living elements is reviewed, the living elements interspersed at the personal space and behavioral territory in public and private spaces show a high usage rate, and in the case where living elements are shared with other families, many living elements are controlled by each family. Also, for living elements with a high possibility of sharing, a high consciousness for public usage is shown rather than elements controlling the territory, and the usage rate as territory controlling living elements is not high. 2. Compared to Japan, in Korea elements that can be placed at a certain location are often used as elements that resolve 'territorial dislocation', using furniture rather than objects. On the other hand, in Japan 'territorial dislocation' is often resolved by establishing a personal territory within the living space. Lastly, compared to Japan, in Korea 'territorial dislocation' is often resolved by maintaining a personal territory spatially rather than territorially.

Recently, as the era of economic cooperation on the Korean Peninsula approaches, the role of the building sector, such as humanitarian reorganization of North Korean housing, is increasing. The purpose of this study is to find out the current location of North Korean housing standards through the North Korean Housing Survey. For the survey, a survey was conducted through 79 North Korean defectors. The main construction methods of North Korean housing are reinforced concrete, steel framed, wooden framed, masonry, and reinforced concrete walled and prefabricated. The residential environment satisfaction items consist of durability, waterproof, heating, ventilation, heat insulation, air tightness, mining, soundproofing, disaster safety, fire safety, and crime prevention. The result is as follows. The housing construction method in North Korea, which lived at that time, consisted of 21 people (30.88%) of reinforced concrete frames, 18 people (26.47%) of wooden frames, 17 people (25%) of masonry walls, 5 people of prefabricated structures (7.35%), and reinforced concrete. Two people (2.94%) were walled. Among these, the wooden frame type had the lowest satisfaction level for each item, and the reinforced concrete had a high level of dissatisfaction in the items of heating, confidentiality, and disaster safety, and the other item had a high level of satisfaction. The masonry wall type has a relatively high satisfaction level in terms of insulation, confidentiality, mining, and disaster safety.

This study aims to propose the improvement direction of spatial organization of orphanage facilities by reflecting the international trend of child welfare facilities including 'enhancement of habitability', 'opening to the local community' and 'multi-functionality' on the basis of ideas of 'right of housing' and 'normalization'. Orphanage facilities are evolving from 'facilities' to accommodate unfortunate children to the concept of the 'community-care', and the residential space is also rapidly shifting to 'cottage' type resembling a residential type of ordinary family so as to enhance the self-esteem and relationship. To suggest the future-oriented changeability of current orphanage facilities, the present study conducted a nationwide survey of child welfare facilities and four Visiting researches of cottage type orphanage with different locations to investigate the appropriateness of housing type, organization of common use space, mode of management and facilities criteria. The results of this study are following: 1) For enhancement of habitability it is suggested that cottage type with various plans in the form of ordinary housing is appropriate, that the number of children per cottage is six or so, and that the number of less than two or three children per room is recommended. At the same time the adjustment of facilities criteria, simplified or complex, is suggested to support a similar residence pattern to ordinary home. 2) Specialized programs must be introduced to establish a base of welfare-network for community children according to features of location and a complex management must be sought in the connection with neighboring public facilities. 3) To secure the residential environment and quality of life for children, the concept of a simple playground space by the current facilities criteria must be broken away to reinforce the network of various outdoor spaces closely connected with living space.

With 106 detached houses where the elderly people lives, this study was conducted to perform a survey of their residential environment. The results of this study were summarized as follows: While the surveyed houses' safety, sanitation and convenience appeared to be positive, with respect to the conditions of location, 73.6% of the surveyed houses did not meet the requirements for comfort. The average area of each space indicated that the bed room was $12.09m^2$, the living room $14.38m^2$, the kitchen $8.96m^2$, the bath room $3.93m^2$, and the rest room $259m^2$. Then, 93.3% of the bed room had the doorsill. Also, 97.2% of the surveyed houses had retrievable space. The forms of the living room door were a hinged door(55.7%) and a sliding door(44.3%). The 43.4% of the finished material of the living room was wood which was highest. The cooking table forms of kitchen were mainly "ㄱ"-shaped(50.0%) and "ㅡ"-shaped(48.0%), and their average height was 815mm. The fuel used for kitchen was mainly the gas which accounted for 93.4%, but 95.3% of houses had no gas-warning devices. Most houses(77.4%) had an integrated type of bathroom and toilet. In addition, 63.2% houses had the stepped difference between the bathroom and other spaces. But they had no a sliding-prevention devices(not for 92.5%) or heating systems(not for 93.4%) in the bathroom.

축산농가로부터 발생되는 악취문제는 지역사회에 중요한 이슈로 떠오르고 있다. 본 연구는 미국의 콜로라도 주의 한 지역(Weld County)에서 거래된 3,355개의 주택이 199개의 축산농가의 악취 때문에 거래가격에 얼마나 영향을 받았는지를 분석하였다. 특히 주택시장에 잠재적으로 존재하는 공간상관관계를 분석에 포함하기 위해 공간 헤도닉 모형을 이용하였다. 결과를 보면 이 지역은 전통적으로 육우와 비육우 농가가 많아서인지 소규모의 육우와 비육우 농장은 오히려 농촌의 전형적인 전원생활의 일부로 주택가격에 양의 파급효과로 나타났다. 그러나 악취로 인한 주택가격의 영향은 축산업의 규모와 업종에 따라 차이를 보였다. 일정규모 이상을 넘어서는 농가와 특정 업종은 주택가격을 하락시키는 것으로 분석되었다. 특히 대규모의 양돈과 양(sheep)은 주택과 근거리에 있는 경우 지역사회에 결정적인 경제적 손실을 초래하고 있음을 알 수 있었다. 축산업의 악취는 부정적인 외부효과의 하나로 지역사회에 사회적인 비용으로 나타난다. 정책결정자는 이 같은 사회적인 비용을 최소화하고 지역경제개발 효과를 극대화하기 위해 이 같은 사회적인 비용을 지역계획 수립에 반영해야 한다. 특히 주택과 축산업의 위치와 특성을 적절히 고려해야 할 것이다.

By this time the main tendency of studying traditional residential building was to find out and analyze the regional and spacial peculiarity. But that kind of study has been set limits in terms of including each building into one category and being researched by the viewpoint of an observers rather than a resident. Due to this kind of problem, the outcome of that study didn't obtain good results. This study, which has synthetically not been investigated until now, have put a little more deep interpretation on traditional residential building, by surveying Andong Kwon family's Yuhoedang-Chongga located 299 Musudong Daejon. The purpose of this study is to investigate the characteristic of construction in the architecture of Yuhoedang-Chongga of the Andong Kwon family, and to develop the viewpoint and analytic process of traditional construction. As the first step to study it efficiently, basic architectural investigation on Yuhoedang-Chongga has been carried out with an actual evidence, and the new viewpoint of traditional residential building has been developed by this survey such as collecting, arranging, analyzing and examining this positive proof. For example, from the house-picture book handed down from that family, the condition of then established was compared with the present state of it. And then this article examines the arrangement, floor-plan types, interior, structures and condition of location. The transition-history of this house was searched into, and the development process of this was examined. The related documents was synthetically analyzed, so the characteristics of this construction was grasped.
