The purpose of the study is to establish the concept of residential standard, and at the same time to investigate the area of the minimum residential standard in the countries of the world through the preceding studies. In addition, it also aims at establishing the objective residential standard by comparing the residential standard of Korea with that of foreign countries, examining the problems and finding out the matters to be improved through the comparison of the residential standard in advanced countries with the minimum residential standard of Korea. The standard residential area, derived from the process of examining the minimum residential standard, will be used as the basic material for the calculation of the reasonable area in the surface plan for the study of low-cost housing development. The method of the study is to establish the concept of residential standard and at the same time to find out the problems in the minimum residential standard of Korea and improvement methods through the comparison of the residential standards in other countries. As the result of the studies focused on the area among the residential standards, it is found out that the Korea's residential area per capita is established as the least in comparison with that of advanced countries. The real area decided depending on the size of social space suitable for living can play a role in improving the degree of satisfaction in the person's living in the residential area. Therefore, it is urgently necessary to make a depth study on the surface area of the minimum residential standard, and it is also required to propose the residential standard and directions for the improvement of the qualitative level rather the quantitative expansion of residential structures.

기존의 산업단지 개발은 대규모 단일 공간 집적형태로 신규 부지를 활용하여 개발하는 방식이나 4차 산업혁명 시대는 스마트한 기술적용과 융복합화를 지원할 수 있는 새로운 입지모델 개발이 필요하다. 따라서 본 연구에서는 새로운 산업단지 공급유형으로 단일공간에 대규모로 집적하는 형태가 아닌 다수의 공간에 분산 배치하여 연계하는 방식으로서 '네트워크형 산업단지'를 제시하였다. 새로운 입지모델 개발을 위해 기업체 설문조사를 실시한 결과, 약 89%의 기업이 네트워크형 산업단지의 필요성을 인식하였으며, 동 산단의 활성화를 위한 조건으로서 '상호 보완기능형성', '결절지간 교통편리성'을 선택하였다. 네트워크형 산업단지는 도시공간과의 개방 연계 지향 및 기반인프라 공유 등을 통해 저비용 고효율화 산단으로 기능할 것으로 전망된다.

The utility interactive sinewave modulated inverter for the solar photovoltaic (PV) power conversion and conditioning with a new high frequency pulse modulated link is presented for domestic residential applications. As compared with the conventional full-bridge hard switching PWM inverter with a high frequency AC link, the simplest single-ended quasi-resonant soft switching sinewave modulated inverter with a duty cycle pulse control is implemented, resulting in size and weight reduction and low-cost. This paper presents a prototype circuit of the single-ended zero voltage soft switching sinewave inverter for solar power conditioner and its operating principle. In addition, this paper proposes a control system to deliver high quality output current. Major design of each component and the power loss analysis under actual power processing is also discussed from an experimental point of view. A newly developed interactive sinewave power processor which has $92.5\%$ efficiencty at 4kW output is demonstrated. It is designed 540mm-300mm-125mm in size, and 20kg in weight.

The important goal of urban renewal is not to reform only Physical environment but to improve people' life quality. people who have been lived in urban renewal area are grouped to owner and tenant. owner of land or house has substituent right but tenant has only house-moving money or rental house by urban renewal. But rental house condition is not good to tenant because tenant has large family, low-income and low grade and it is essential to provide rental house for low-income class and it is worth to analyze tenant house problem The purpose of this study is to analyze the problems of public rental house and to presents solutions. The study was done in following process. First, the literatures on this subject were investigated to seek the problems of public rental house. Second, Survey were done on the staff, who works in the cooperative housing redevelopment and whose jobs are officer, consultant, real estate introducer and designer, to seek problems and solution of public rntal house. survey which is made by three group. one group is made by people who already lived in tenant APT, second group is made by people who are waiting for moving in tenant APT. Third group is made by specialist who has many experience-more than 3years- to urban renewal. Third, the Correlation Analysis was used to analyze the relation between the Area and dwelling satisfaction. Fourth, tenant policy' altenative is presented to solve tenant APT' problem which is analyzed by this study The results are as follows : First, tenant APT' size Which is regulated to 30-$45m^{2}$ is enlarged to more than $45m^{2}$ because tenant family is made up averagely of 4.8 persons. Second, tenant APT' rental cost is reduced to 100 thousand won. Third tenant APT' arrangement is divided from owner because tenant and owner want to live in group by group. Fourth, tenant house type is changed to various house type because tenant is not familiar with APT

The nursing-care insurance system started in April, 2000 in Japan. It was a kind of business opportunities for a lot of private entrepreneurs. They came into this care service business from another type of business rapidly. They opened the pay nursing homes with 24 hour nursing. However, the expense load of the nursing-care insurance system was large, local governments started controlling on total numbers of facilities with 24 hours nursing in 2006. So the group houses besides the pay nursing home without nursing care are paid to attention. The pay nursing home has been often managed by the nursing business. Most of the group houses are managed by community based NPO. This study is a case study by the visit and the interview form for one of the group houses. The group house "Shalom Tsukimino" in Kanagawa started operations comparatively at early time among them. Through the study we recognized that a lot of people were helping the NPO as a community service. So they can manage the group house and people who live there get the services with low cost. They show that they separate residence and nursing and use the community service efficiently. We can find a new direction in this case for the life in elderly.

As the government announced Real Estate Policies on August 02, most areas except for Seoul cities face increasing business risks. Moreover, the government control over financial sectors' loan leads to the highly possible contraction of new distribution markets. The market trend could bring about the reduction of new demand in PF (Private Financing) business that large construction companies mainly concentrate on, and even the business already obtained has a high risk of being distributed, which could result in substantially low profitability. The currently unstable financial structure of most construction companies is caused by the hike of the prime cost of foreign plants except for that of a few construction companies. If PF (Private Financing) business also faces a difficult situation in such a financial condition, even large construction companies come to have the high possibility of a deficiency in credit rating. Accordingly, the major business that large construction companies concentrate on needs the sufficient business review. It is desirable to make a bid for business guaranteeing stability rather than business solely in consideration of profitability, when participating in a competition for a new construction contract.

The purpose of this study is to examine the awareness of apartment residents on their using tendency of community facilities established in apartment complex in order to verify a role that such facilities play in making contributions to lives of apartment dwellers and to analyze their using tendency of the facilities and subsequent problems. The study produced the important findings as follows. First, the level of exchange among residents and their satisfaction were raised high in the apartment complex that offered substantial community facilities. Second, in regard to physical aspect, community activities among dwellers were brisk in the apartment complex where community facilities were organically connected. Third, fitness center, shower room and golf course were excessive in terms of space provided while the space alloted for G.X room, a place used exclusively for class, was insufficient. Fourth, the analysis of using tendency and preference level showed that fitness center, shower room and G.X room were the required facilities. The rooms for using PCs and watching DVDs and the singing room were found to be unnecessary because such facilities were low in the effectiveness when the operating cost was considered.

Implementing a home modification to enable elderly's safe and independent living is the key plan to realize their aging in place. South Korea in which had entered an aged society is not yet vitalized in home modification for the elderly compared to that of welfare-developed countries, and South Korea provides support that is limited to the low-income elderly. Therefore, this purpose of this study was to analyze the laws related to the home modification, the present condition of home modification support, the standards and guidelines in home modification, the support in house modification cost, and supporting organization and working force in the home modification. Through the analyzing process, this study examined the current situation and problems of institutional support in the home modification for elderly and the proposed plan for institutional improvement. The suggestions based on the results are as in the following. 1) Home modification support law(act or regulation) is required to be improved 2) Home modification support system correspondent to aging process should be provided regardless of their income levels. 3) Delicate plan standard and guideline are necessary for a process of implementing the home modification for the elderly. 4) Information on life behavior is in need for the implementation of elderly-customized home modification. 5) Cost for the home modification should be considered to cover by the Act on Long-Term Care Insurance for the Aged. 6) Housing Welfare Center and Housing Welfare Professional should be actively utilized for the home modification support institution and work force.

The need for off-site construction has increased in the construction industry in Korea in recent years due to the enforcement of the 52-hour workweek, the increasing age of workers on construction sites, the deepening dependence on overseas workers, and the stagnation of productivity in the construction industry. Thus, studies on OSC started in April 2020. In addition, as a national policy study advocating the modular construction method, which is one of the OSC methods, was completed in the first half of 2019. 70 housing units in two complexes that satisfied the Housing Act requirements have been supplied to citizens. However, although modular construction methods have been recognized as a dramatic construction method that achieves shortened construction schedules and solves the issues of cost reduction and the shortage of technical workers on sites by combining the advantages of the manufacturing industry and applying the economies of scale, realistically it has issues due to the rising cost of steel and a low pre-fabrication ratio. Moreover, the construction time of core parts, such as those built by pouring concrete, has become a factor that hinders the shortening of construction times. Thus, this study aims to propose a precast concrete(PC) modular construction system, which fuses three-dimensional infill as an interior finish material and a three-surface PC module that can acts as a structure for a construction method that is economical and can shorten construction time.
