To investigate opportunities for wood frame housing and to activate wood frame house construction, trends of construction activities. preference about housing, and building codes related to wood frame housing were discussed. And two models of wood frame house were developed and construction cost was analyzed to compare with comparative masonry houses. The results obtained were as follows: 1. While 77.8% of people prefer single-family houses, majority of people(74.9%), ironically, possess multi-family houses such as apartments Wood work cost was ratio of 4% of total building cost. while wood material cost accounted merely for 11 % out of total building material cost. 2. Building code was not major barrier to residential house at height under 13m. The building code regulated major structural member and family boder wall of multi-family house to be built with fire retardant material. 3. The proper wood frame house was analyzed of town house or villa type locating in suburban of big city with hot ondol system for the upper middle class. 4 There was no difference in construction cost between western style wood frame house and comparable masonry house, but construction cost for Korean style wood frame house is 27% higher than that of comparable masonry house. It was necessary to reduce materials and cost down by prefabrication technique for both style of wood frame house.

This study is to analyze the transfiguration of the plan of the Japanese-Western eclectic houses in the process of the change in the living style and modernization. Twenty four Japanese-Western eclectic houses. which were located in Teagu Province and constructed during the period from the end of 19th century to the year 1945. were surveyed and analized about the original plans and the process of their spatial tranfituration. The results of this study are as follews 1) In the original plans. the bathroom, toilet and entrance hall in the residential space and HUSMA(wooden sliding doors) for separation of the rooms had been installed. 2) After the Liberation. the rooms of the residential space had been transfigured from TADAMI. JASHIKI. kitchen and toilet etc. to ONDOL. ANBANG. kitchen and toilet etc of the Korean traditional style. From 1980's they composed of living room, dining room and entrance hall of the Western-style. 3) From the liberation to 1960's. each room of residential space had been transtigured greatly form the Japanese style into the Korean style. Thus as the entrance hall. bathroom and TADAMI has been disappeared. DNDOL and MARU reappeared. Since 1980's bathroom diningroom and entrance hall ef the Western-style have recomposed in their residential space. But ANBANG is still used as a major living space in the surveyed houses.

The purpose of this paper is to derive attractive items of 'Hanok' in order to preserve 'Hanok' in urban area, focused on the 13 preceding studies which have got in respect of image, satisfaction, preference, awareness and advantage of 'Hanok' in urban area revolved around the latest studies. This study is analysis of questionnaire items and results of 13 preceding studies. And attractive items are classified with general and overall survey items, advantage of 'Hanok' in urban area, and image of Hanok-density urban area. These can also be classified with 5 items which are space, health, material, form, and image of 'Hanok' in urban area. As a result, Space items are composed with 'use of a space', 'cosiness', 'garden' and 'floor and ondol(korean floor heating system). Health items are composed with 'lighting and ventialtion', 'a sense of the season' and 'natural material'. Material items are composed with 'natural beauty', 'wooden', 'changhoji(traditional Korean paper made from mulberry bark for doors and windows) and hanji(traditional Korean paper handmade from mulberry trees), 'rafter' and 'new materials'. Form items are composed with 'attractive appearance', 'simply decoration' and 'traditional elements'. Image items are composed with 'crowding', 'traditionality and historicity', 'dichroism' and 'warmth'.

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.

Owing to the energitic studies of the leading shcolars, some paradigmatic theories on the history of Korean dwellings have been suggested. They constructed periodization of their own and defined characteristics of each period with very limited historical materials. However the new historical materials have been discovered in the neighboring academic fields, which require to review the existing theories. This study aims at restructuring periodization in the history of Korean dwellings during the age of The prehistory and The ancient Kingdomes. Through the study, the existing theories on the same period are revived and evaluated based on the new materials. I suggest a new theory on the periodization and the characteristics of each period: a. the paleolithic period(6,000,000 B.P.-10,000 B.P.) : natural shelter, the emergence of man-made dwellings b. the neolithic period(10,000 B.P.-1,000 B.C.) : construction of pit house c. the bronze period(1,000 B.C.- 300 B.C.) : construction of semi-pit house d. the early metalic period(300 B.C. - 300 AD.) : construction of house on the ground level development of the Ondol system e. the ancient kingdomes period(300 AD - 700 AD): classification of housing type

Soengyo-jang has some characteristics as the most great house, the special functions, and the non-regional type of house form. And it has constructed continuously for two centuries by many owners in the different generations, It needs a special research method ; which are consist of a) comprehension of background information from documents and oral instructed materials, b) pursuit of design process through the building survey, and c) theoretical interpretation about 'collectivism'. From the results of this research, it is revealed that the architectural purpose of this house was constructing 'a great manor'. At first phase, it had been a single ordinary house, at second, it had expanded to a complex including many housing clusters, and finally became to expand its dwelling territory into whole village. Its expansion was progressed by the four collecting phases of which were building, building cluster, group of clusters, and topological setting. Main design elements operated in each of collecting phases ; they were partial element of , exterior spaces of , a linear building of , and a pavilion of . The last two elements were also powerful datum.

Heating pipes burst was occurred in the apartment complex that was applied floor radiant heating system. There were two opinions for the cause of the bursted heating pipes that was the flaw during construction and defects in the product and also there were conflicting among them. Officials analyzed it in order to investigate the cause of the rupture. Tensile test results showed different tensile strength between the lower part of heating pipe and the upper part of heating pipes. The lower tensile strength is maintained while the top was not secured. The reason why rupture heating pipes is that flow velocity isn't secured and then the air get stagnant. Stagnant air makes hardening. It is caused rupturing. The proper flow rate was confirmed 0.166 m/sec after experiment. It isn't make stagnant air inside heating pipes.

Sudden infant death syndrome (SIDS) in Korea remains a poorly-understood subject for both professionals and the public. Recent reports have emphasized ethnic differences in SIDS rates, suggesting that making adjustments in child-rearing practices may contribute substantially to SIDS reduction. Two of the three major risk factors for SIDS-vulnerability of the infant and exogenous factors-need to be understood in particular depth due to their broad scope and sociocultural grounding. This paper presents substantial issues regarding preterm birth and male gender on infants' vulnerability to SIDS in Korea. Practices of caring for healthy infants are addressed in the context of sleeping practices, including sleeping position, bedding arrangements, sleeping on the floor, the back-to-sleep position, high indoor temperatures and ondol floor heating, and swaddling. Professional and social awareness about how to reduce SIDS should be raised by promoting a better understanding of risk factors in the context of ethnic and cultural variations in child-rearing practices.
