본 연구는 지속적으로 구조적 변화를 겪으며 증가하고 있는 외국인의 인구와 주택 소비의 변화가 본국과 이주국의 주택 시장 양쪽 모두에 영향을 미친다는 사실을 밝히는 것에 목적을 둔다. 서울의 조선족 주택 시장의 형성 원인과 변화는 임대료 시장에 있어서 내국인 주택 시장과는 다른 '임대료의 고정 효과'로 인하여 외국인의 유입이 지속적으로 발생하는 것으로 나타났다. 특히 순환 이주 의향이 강한 조선족 집단에 의해 분화된 주택 시장의 밀집은 더욱 심화된 형태로 변화하고 있다. 한편 한국에서 이주 경험이 있는 조선족들이 주요 주택 소비자로 부상하면서, 연길시의 부동산 붐을 일으켰다. 조선족의 주택 투자는 연변 대학을 기준으로 '서부'에 집중되어 있는데, 연길시의 주택 공급에 영향을 미치는 도시 기본 계획과 밀접한 연관 관계를 가지고 있다. 이와 같은 이주자의 초국가적 주택 소비로 인하여, 본국과 이주국의 주택 시장을 연결함으로써 두 주택 시장에서 발생하는 여과과정을 동시에 일으켜, '초국가적 주택 여과 과정(Transnational housing filtering process)'이 발생하게 되는 것으로 나타났다.

In Korea, the modular construction method was applied to the construction of facilities such as military barracks and school dormitories, beginning with the pilot project of Seoul New Elementary School in 2003. In 2017, public modular houses were supplied to Busan(Yongho-dong) and Seoul(Gayang-dong), and modular housing is expected to continue to be supplied in the future. However, there is no clear construction standard for the modular housing construction yet, and there are few cases where the infill modular system is applied. Therefore, this study established the work breakdown structure and proposed a standard process focusing on the infill modular system applied to the construction of Dujeong-dong modular house in Cheonan. Level 1 of the work breakdown structure by construction stage of Infill modular was defined as modular manufacturing, assembly, and finishing process. Level 2 was defined as preparation, modular production, modular infill, modular fixing, floor plastering, building finishing, and other site finishing. Level 3 is defined as 57 detailed unit work of infill modular construction. The standard process of infill modular is proposed for the assembly stage that is commonly applicable to infill modular housing construction. The results of this study can be used for the process plan, transportation plan, lifting plan of modular housing construction.

The purpose of this study is to explore the formation process of housing notion for later life of the elderly which is based on one's lifetime housing experiences. Qualitative data was collected through in-depth interviews with 6 highincome, highly educated aged women, who could select their housing and move voluntarily in old age and explain their housing experiences logically. The findings of this study showed that housing notion for later life was formed through a complex process of individual personality, lifestyle, housing experiences, housing values, housing market and period background as well as socio-demographic characteristics. This qualitative study has a significance as a holistic approach to reveal the lifelong experience of elderly individuals which had not been to deal in the quantitative research of housing for the elderly in the meantime.

The environment which has been destroyed for the national growth since 1960's would seem to offer infinite resources to human, but now, the existence of human being is threatened by the development thoughtless for the environment. The World Powers have concentrated on green growth with eco-friendly resource since the end of 20th century. Korea suggested that the vision was the low carbon for green growth in 2008. It is necessary to supply Long-Life Housing in the green technology in terms of the sustainable housing development based on various life style, life cycle of the residences, the restrain remodeling and redevelopment in construction. This study is aim to establish the development of maintenance process to make continuous inhabitation of Long-Life Housing that has the separated SI for maintenance, durability, variability and remodeling. The maintenance for Long-Life Housing is very important to have more than 50~70 years the long term of life cycle in comparison with Housing. Also, the roles of manager and user are important parts in Long-Life Housing. The present maintenance for Housing is shift and repair works by the routine maintenance and demage. However, The maintenance for Long-Life Housing should consider movement and flexibility. In addition, Long-Life Housing requires the proper process of maintenance because it is different from Housing in housing concept, design and constructions stage. Therefore this study shows the efficient maintenance process for Long-Life Housing.

In this paper, research on the mold design of motor housing produced by the HPDC process was conducted using computer simulations and experiments. Recently, automobile parts have been required to be light and have high strength. The die casting process was used to manufacture automotive motor housings. In the die casting process, the control of casting defects is very important. However, it has usually depended on the experience of the foundry engineer. For the analysis of the manufacturing process of motor housing, the finite element method is applied. Through the simulations using commercial software, the filling pattern and product defects could be confirmed. The analysis results obtained from the filling behavior of the casting process agreed with the experimental results. The computer simulation results of filling behavior were reflected in the optimal mold design of motor housing.

The recent paradigm shift in the construction industry has led to a growing demand for industrial construction. In particular, interest in modular housing, one of the areas of industrialization architecture, is soaring. Modular housing is a construction method for completing a building by transporting factory-built modules to the site and assembling them. However, modular housing in Korea has various problems such as errors in design books, lack of factory drawings, and lack of on-site construction plans. BIM is a tool for accumulating, producing and managing various information through 3D models and is a solution to solve various problems of modular housing. In this study, problems of modular housing and BIM utilization of modular housing were presented as ways to ensure the quality of modular housing. Therefore, this study analyzed the problems that are occurring in the construction process of modular housing. And, to address the problem of modular housing, BIM utilization measures were proposed for each modular process step. However, the application of BIM in domestic modular project is currently being carried out in pilot research project. Because of this, the BIM utilize method for modular housing is limited based on the BIM use for general projects and the examples for some modular pilot projects.

A process sequence of multi-operation cold forging for actual application in industry is designed with the rigid-plastic finite element method to form a constant velocity joint housing(CVJ housing). The material flow during the CVJ housing forming is axisymmetric until the final forging process for forming of ball grooves. This study treats the deformation as an axisymmetric case. The main objective of the process sequence design is to obtain preforms which satisfy the design criteria of near-net-shape product requiring less machining after forming. The process sequence design also investigates velocity distributions, effective strain distributions and forging loads, which are useful information in the real process design.
