As being inconvenient to apply reinforced concrete structure to high-rise buildings. it is applied steel structured system. Therefore light-weight wall systems are applied as partition wall to reduce the self-load of the building. But. the required performances of a light-weight wall are not evaluated systematically. As a field survey result. partition walls of house-to-house and room-to-room were not showed their respected performances. so the dwellers are feel so worse the quality of the whole building. In steel-structured high-rise buildings especially. occupant's dissatisfaction concerned indoor noise was high because curtain wall systems having a high air-tight performance isolate the outdoor noise making masking effect. Also to suppress indoor air movement. stact effect must be concerned. Therefore wall systems which have high performances of sound insulation and air-tightness are required in high-rise buildings.

The purpose of this study is to analysis the change of rural house type in Gyeongbuk province. There are 13 Gun(a kind of administrative district) areas in Gyeongbuk province. According to definition of rural area, the scopes of the research of rural houses limited the 12 places rural area(Gun area, excluded Ulleung-Gun) of Gyeongbuk province. The method of study is to compare and analyze about housing situation, structure of house, housing type and housing area etc. through the statistical data of each Gun area and other various data etc. during these 5 years. As a results of the analysis : 1) The supply ratio of housing is steadily decreasing in rural areas. 2) The houses of rural areas are changing from a detached house to multi-household house and small apartment by development near the rural area. 3) The number and area of commercial buildings are gradually increasing because of urbanization of rural areas. 4) The most houses inside area scopes in the rural area was from $60m^2$ to $85m^2$ area. And the family types of rural house are changing from large family to nuclear family and single households. 5) The structure of rural houses is changing from the brick house type to lightweight steel construction house because of cost-cutting of construction and easy way to construct etc.

Most of all furniture had been produced from wood, because it is easy to obtain from our surroundings. As time goes by people want to decorate their house with new material furniture. Because it is outcome from development of material technology & industrialization. Furniture design trends of twenty century are not only the fruits of great talented furniture artists but also high-tech material engineers. In this study, I deal with a tubular steel, as an one of the most important material of furniture, and also tubular steel furniture manufactured by a cantilever method. This study researches what are special features of it, how can designers utilize it to furniture and how do they conquest defects of the material such as a sensation of coldness, hardness and so on. In this context, It is possible that create not only new shape of furniture but also new style of space through new technology innovation.

The technology-intensive unit modular method of factory production method is attracting attention by the limit of the labor-intensive and field centered wet construction method. In recent years, the unit modular method has been applied to the construction of schoolhouse and BOQ(bachelor offices' quarters), dormitories, etc. But the modular method still is not used in housing construction by the lack of verification of resident performance and construction cost. Therefore, this study analyzed the economics of modular house to vitalize the constructed residential building by modular method and to develop the modular method. According to the study results, the construction cost of the modular house was analysed more about 6.2% expensive than that of the existing housing. However, if the construction duration of modular house is shortened or the productivity of modular house is increased, the construction cost of modular house will be similar to the that of the existing house.

The area of facility horticulture in Korea is increasing rapidly, the single-span pipe house which uses galvanized steel pipe as the main rafters occupies 78.7% of the facility area. Lightweight structures such as the single-span pipe house are vulnerable to meteorological disasters such as strong winds, economic losses of the state, local governments and farmers are continuing as construction does not meet the design standards. In order to minimize economic losses in the horticultural specialty facilities sector, the Rural Development Administration has been operating the horticultural disaster resilient standard for horticultural specialty facilities since April 2007. The only standard for the pipe connector is the disaster resilient standard, there is no standard for the uplift capacity of the house pipe foundation and the research on it is also insufficient. The purpose of this study is to investigate the characteristics of uplift capacity according to the foundation type, compaction ratio and embedded depth through soil box test. The results of the maximum uplift capacity according to the type, compaction ratio and embedded depth can be used as the basic data for the basic design of the pipe house conforming to the disaster resilient standard. Due to the limitation of soil box test, it may be different from the behavior of pipe house installed on site. In the future, the field test and the actual pipe house should be made and supplemented by comparing this result with the field test values.

Cold-Formed C-section and Lipped C-section are commonly used as structural members of steel houses in Korea. Both are made of SGC41 steel. However, special Cold-Formed Sections with unique cross sectional shape have been developed and widely used in advanced countries. This research focused on the newly developed thin-walled Cold-Formed Sections which possess not only high strength and stiffness but also other advantages in construction. A series of compression tests was conducted to investigate the structural behavior of a compression member, including its load carrying capacity. Test results were compared with analytical study results.

The use of light steel framing as a method of house construction has increased significantly throughout Japan, United States and Europe. Industrialized unit method are prevailing in developed countries. Unit modular house industry has supported an intensive technical development, and housing systems are now available, which are highly adaptable in form and use. Unit modular house have their own merits and demerits, but the more crucial aspect is that the constant design standard should be applied in each design procedure. It entails the necessity of industrial housing development on the open system basis. This paper describes the general forms of factory product system of unit modular housing system in Korea, United States, Japan. And this study attempts to propose the unit factory product system of which the rate of pre-fabrication is the biggest, that can cope with the demand of user on the basis of open-system.

This study estimates steel house shear wall's seismic performance depending on trend of seismic design. As a result at cyclic-test, the capability of energy dissipation about X1SPCH during this test is good enough. The capability of energy dissipation of X3SPCH and X4SPCH was better than that of X1SPCH. The X2SPCH which is similar to real X-braced shear wall has better seismic performance than shear wall braced with structural sheathing materials on pseudo-dynamic test.
