The purpose of this study was to identify the characteristics of housing product through housebuilders' strategies. As a methodology for this study, literature survey and questionnaire survey were used. Questionnaires were delivered on mail to 232 housing-builders and return rate was 34.1％. In summary, housing product was characterized long gestation period, periodically building cycle, future uncertainty of market volatility, maximization of land development gain, utilization of public fund for continuous building activity, moral hazard by accidental bankruptcy. Therefore private housebuilding could be defined speculative industry.

For manufacturing upper housing product of mechanical control valve, the progressive drawing process was conducted experimental. Then, the center of the product was cut to measure the thickness of the product. As a result, the following conclusions were obtained. By means of a stand-alone pad provided with sufficient pressure, it is possible to prevent the occurrence of wrinkles in the die pad product of the drawing process. As a result of the experiment, it was considered that the flange bottom of the product and the lower edge of the product are made thick in thickness, the top edge and the top surface are thin. It is considered that this is due to the size and roughness of the entrance edge radius of the die in the drawing process, and the inflow of the material by the die pad.

정부의 대량주택공급정책 등으로 인한 고객중심으로의 시장변화는 자연히 주택 공급업체로 하여금 품질의 경쟁시대를 맞이하도록 하였다. 이러한 품질경쟁시대에서 빠르게 변화하는 고객의 요구품질에 부응하는 주택상품기획 방향을 모색하기위한 선행연구로서 현재 우리 주택시장에서 이루어지는 주택상품의 단위세대 품질의 차별화 사례유형에 대한 실태분석을 실시하였다. 조사 및 분석 결과 많은 사례들이 단순히 마감자재의 고급화나 일시 유행적인 친환경자재의 사용과 부분적이고 단속적인 생활편의품과 설비시스템의 건축요소와의 결합 등을 통한 상품풀질의 차별화를 꾀하고 있었다. 본 연구결과 주택상품의 차별화 기획은 고객을 중심으로 하여 단위세대의 품질 요소 중 건축지향적인 평면 및 인테리어요소와 기술지향적인 설비 및 제품요소의 유기적인 융합을 통합 품질의 차별화가 이루어져야 할 것으로 판단된다. 향후 주택상품기획단계에서는 고객 개념의 재정립을 통한 사람중심의 지속가능한 차별화 계획요소에 대한 연구 및 고객 지향적 주택상품기획 절차의 마련이 필요한 것으로 연구되었다.

최근 고객중심으로의 시장변화는 자연히 주택공급업체로 하여금 품질의 경쟁시대를 맞이하도록 하였다. 이러한 품질경쟁시대에 부응하는 주택상품 기획을 위하여 단위세대 품질의 차별화 사례 및 대상 부위에 대한 유형분석 등을 실시하여 공동주택의 단위세대에 대한 품질의 차별화 유형 분류체계를 구축하였다. 건축적 요소인 평면요소와 인테리어요소는 공간위계를 기준으로 품질요소를 세분하여 분류체계를 구축하였고, 사용자 편익과 관련 있는 설비시스템부위는 친환경성, 안전성, 에너지절약효과, 편리성으로 구분하여 분류체계를 구축하였으며, 제품요소는 가구와 설치제품 및 편의품으로 구분하여 분류체계를 구축하였다. 향후 이 분류체계는 공동주택상품의 마케팅 전략수립단계에서의 제품 포지셔닝과 상품기획단계에서의 상품의 차별화요소 결정에도 유용하게 활용할 수 있을 것이다.

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.

Product characteristic approach and hedonic method were explained and applied to demand behavior of housing for 360 households sampled from four districts of Seoul. Th major findings are: 1) Housing prices are determined by housing characteristics, i.e., basic structure, interior space, interior quality, and neighborhood quality. 2) as income increase , the demand for basic structure, interior space, interior of quality, and neighbor hood quality increases. As compared to the counties that have advanced housing financial systems, income elasticity form housing characteristics was low. 3) householder's educational level has insignificant effects on the demand for neighborhood quality. 4) the housing need of family is different to a family life cycle. In the first stage, the increase of income enhances the demand for basic structure. interior space, and interior quality, but inversed with neighborhood quality. In the second and third stages, the demand for basic structure, interior space, and interior quality increases as the income increases. 5) It is predicted that the larger the family size, the more housing space is required. But in the low-income group, an increase in family size results in a decrease in the demand for interior space because expenses for food and education are indispensable ones. In the middle -income group the demand for interior space, interior quality increases as the family size increases, In the high-income group, the larger the family size the more interior quality is demanded. As mentioned above, the demand for housing is derived form characteristics and the demand behavior far housing characteristics is varied with individual household's characteristics. Therefore, the fact that different housing needs according to various income groups should be considered in housing policy.

The purpose of this study was to analyze the Characteristic and Changing Process of Refugees' Housing in the Korean War. Refugees' Housing is one of the unique forms of housing that emerged during the acute situation in the war. During the Korean War, Busan became the Wartime Capital and various housing policies were implemented for the influx of refugees. Various types of housing appeared in Busan during the war, and the type analysis and characteristic of these types were revealed through literature and case studies. Accordingly, the product of study was indicated in the meaning of the housing restoration policy enforced during the war and the housing type exhibited by refugees from the perspective of housing.

Resin transfer molding process has been widely used in the automobile industry, because the product with large area can be manufactured easily and the cost for the manufacturing is lower than that of compression molding and hand lay up method. Since RTM process is suitable for large bus housing panels, in this work, the composite housing panel was manufactured by RTM process and the mechanical properties, surface quality and the condition of manufacturing process were studied.

A vacuum ladling die casting system is suggested as a means to obtain a high vacuum level. A high vacuum of 17.8 mmHg is obtained by sealing the inner space of the mould. The sample product is a rear-head housing for an auto-compressor, and the die-casting with 6-cavities was conducted. The flow analysis shows that the filling speed during vacuum ladling is faster than for a non-vacuum system. The air holes in the sample product were too small to be seen with the naked eye in X-ray films. Density tests show that the high vacuum ladling system reduces the internal porosity as much as 57.8% when compared to the non-vacuum system. A defective rate of only 0.17% was found from leak testing. The results of this research prove that the high vacuum die-casting process is useful for manufacturing of aluminium components under high internal pressure.
