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.

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.

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.

최근 주택시장의 경향을 반영하여 도시형 타운하우스의 개발이 지역에 따라 다양한 형태로 이루어지고 있는 실정이다. 그러나 생활주택으로서의 특성과 소비자들의 니즈를 잘못 판단하여 도시생활에 적합하지 않거나 무분별한 지역개발의 산물로 전락하는 등 많은 시행착오를 거듭하고 있다는 점은 매우 안타까운 일이 아닐 수 없다. 도시형 타운하우스의 장점은 사생활 침해나 가구 간 소음문제가 없으며, 개별정원과 주차공간의 확충, 접지성 확보, 개성 있는 내·외부 계획을 할 수 있다는 점이다. 또한 방범, 방재, 보안 등 공동관리 효율성, 출입문 분리를 통한 연속벽 건축, 중앙광장, 공원 등 공용공간 계획 등의 공동주택 측면의 장점도 갖추고 있어서 도시형 주거유형으로 발전할 수 있는 가능성은 매우 높다고 본다. 따라서, 본 연구에서는 도시 생활공간에 적합한 주택상품개발을 위한 기본 방향을 구축하여 도시형 타운하우스의 역할을 극대화하는데 그 목적이 있으며, 생활주택으로서의 공간적 요소와 기능적 요소 및 재료활용을 파악하여 소비자의 니즈에 부합하는 도시형 타운하우스의 주택상품개발을 위한 가이드라인을 제시하고자 한다.

자동차용 LPI 연료필터 하우징의 냉간단조 공정에 대한 성형해석을 수행하였다. 변형과 하중의 분배를 고려하여 금형과 시제품을 제작하였다. 또한 기존 모델과 신규 모델의 유동 특성을 분석하기 위하여, 유동해석을 수행하였다. 유동해석 결과, 두 모델은 동등한 압력강하량을 나타내었다. 기존 제품 대비, 상부 하우징은 16 g, 하부 하우징은 30.5 g이 감소하여, 총 46.5 g의 중량이 감소하였다. 안정성을 검증하기 위해서 기밀시험 및 내압시험을 수행하였으며, 시험 기준을 만족하였다.

The amount of multi-aged housing more than 15 years since the completion has increased, and the real estate market caused by apartment remodeling has also increased. The domestic mortgage loan regulation on relocation expense caused by remodeling apply to same limit as that for mortgage loan newly-built apartment. The excessive government housing regulation could be an obstacle for the occupants residential stability of remodeling apartment. To suggest methods for government housing regulation of residential mortgage loan related to remodeling, examples for mortgage loan regulation and mortgage products were studied and compared. It is pointed out that regulation on occupants relocation expense caused by remodeling has to be relaxed and mortgage product development are needed to boost remodeling project.

"Environmentally Sound and Sustainable Development (ESSD)" is a key word in recent years. The construction industry, have put a great influence on ergonomic and sustainable environment. Recently, "green building certifications", such as Indoor Air Quality (IAQ) and eco-friendly material regulation have been established. With this regard, new construction and aged-housing remodeling projects are required to meet these certification criteria. Multi-housing residents have great concern on eco-product, since many cases are reported that Sick Building Syndrome is caused by toxic substance from building materials. Aged-housing remodeling project is very unique in that building residents are selected prior to design phase. Therefore, the analysis of resident's need for building materials in aged-housing remodeling is relatively easy compared to new building construction. As such, it is very important to analyze their preferences for eco-friendly materials prior to project execution. The purpose of this study is to find the needs of residents and priority of their needs. Based on their needs and priority, this paper provides a new strategy in using environment-friendly materials and maximizing their satisfaction level when aged housing remodeling is constructed. In addition, this paper provide new criteria in selecting new developed environmental materials in remodeling projects for the purpose of improving the safety and health level in construction industry.
