This study examined the apartment sale in lots system from 1960s to 1970s in Seoul from a historical perspective, with the focus on the concept and changes of pre-sale in lots system. By tracing back historical context and application of the system in that period through the analysis of the advertisements for apartment sale, we found out the hidden side of the apartment pre-sale in lots system from the public's point of view, and its impact and meaning on the formation of our current residential culture. In the 1960s and 1970s, the apartment sale in lots system based on the pre-sale in lots system formed strong seller's market and it has been the main reason for imposing the wrong residential awareness that led the public to recognize housing as a means of property growth. Even now, the current apartment sale in lots system remains to be a supplier-oriented one, and lots of people tend to regard housing as investment method. That is, this mechanism is not only still working but one of the fundamental causes of impoverishing our residential culture. It is necessary to reconsider the pre-sale in lots system and the apartment sale in lots system in relation to the public of housing.

One of the problems in using renewable energy sources is great difficulty of stable and sustainable supply. Because the fuel cell can provide stable and sustainable supply of energy sources without regard to external conditions, however, it will become one of the most useful renewable energy sources for buildings that need stable energy supply. For practical application of PEMFC system to common household, the data of household energy consumption are analyzed by electricity, cooking and heating. From the result of the data analysis, practical application methods of PEMFC system to household are designed to several models. The aim of this study is to establish a plan of practical application for applying Polymer Electrolyte Membrane Fuel Cell(PEMFC) system to the households.

Citizen participation in local redevelopment has recently been regarded as essential, since progress in democracy and diversified public interests have contributed to more importance being placed on citizen participation in the implementation of public policies. While the importance of resident participation has been increasingly emphasized in principle, in reality more effort is still required in its application. We need to develop practical strategies of collecting community opinion in order to reflect it in public policy, if we are to achieve a resident and citizen-centered society. The purpose of this study is to develop an image map construction tool that can be applied to the "Maul-Mandulgi" projects as a visualized method to facilitate the exchange of opinions and work toward agreements. The tool is intended to assist public discussion by visualizing policies and plans and reducing the possibility of misunderstanding, so that residents can properly respond to the plans. Second, this study will verify the effectiveness of the tool in the application to local community workshops. The main research method is participant observation method and field study. Major findings are as follows, First, every resident who had participated in previous workshops gathered together, used the tool and represented their opinions unusually more than once. Each resident tried to make sure that other participants appropriately understood his or her opinion. The workshop finished when all participants agreed and produced a consensus. The workshop took much less time, which is in stark contrast to previous workshops in which it took significantly more time to collect opinions. Second, it proved that residents in the redevelopment area can strike a broad agreement by themselves on a method and direction for residential improvement. In previous workshops, conflicts between residents developed over the choice between the two methods, of local improvement and total demolition prior to multi-housing construction. In this study, opinions of residents were not limited to the two methods by finding a winwin solution. Third, the use of the tool kit for image map became efficient for inactive residents to develop their own opinions in regard to the direction and orientations of the residential improvement process. In addition, for those who have either no or a slight understanding of the residential improvement projects, the tool can provide access to information and knowledge. This study concludes that the developed tool for imaging of the redevelopment projection like a design game, rather than using forms of text and speech, can be a useful tool in collecting opinions and forming an agreed opinion for forthcoming residential improvement plans.

The application of solar energy in residential building is general and natural in today. And application methods of solar thermal energy is divided in two kind of form, single evacuated tube and flat-plate form. Then in this study, the efficiency of single evacuated tube and flat-plate system is compared by total and effective area considering the time receiving the solar radiation between 24 hours and the specific time(10:00~15:00). As a result of the experiment, single evacuated tube and flat-plate collector's efficiency is varied by the quantity of solar radiation. And especially, the flat-plate system is more affected by outdoor temperature. Therefore the application of solar thermal system should be considered the solar radiation and outdoor temperature.

The purpose of this study is to find how to use the terrace-house which can protect development thoughtless for the environment of hilly sites and make good hilly residential area. But there are some problems not to be able to apply terrace-house on hilly sites under such korean circumstances. So, to find these problems, it is analyzed different things between terrace-housing and high-rise apartment housing. This analysis finds some reasons why terrace-houses can't be applied in korea. Of these reasons to interrupt application of terrace-house, this study is to solve problem of density and to suggest the design proposals considered by habitability.

The purpose of this study is to consider the community design applications in the senior collective housing in Hyogo Prefecture, Japan. It was performed by two programs, application program and space design program. The former is focused on the participation of residents to the planing and design process, sharing, community activity, social interaction, and management by residents. The latter is focused on the common space(room) design. It was also performed by literature review, observation, and interview. The findings for the community design as an application program in SCH are almost the same with those in CH. But, the level of common meal and common laundry in SCH is lower than that of CH. And space design program is focused on the location and scale of common space(room) which is related to the number of users. As a result, the positive possibilities of SCH as a new residential type for the self-reliant seniors can be confirmed. The difference of community design application between CH and SCH is caused by various factors such as senior's health conditions, economic factors, and Japanese life style.

현재 우리가 사용하는 에너지의 대부분은 화석 에너지로서 멀지 않아 고갈될 것으로 예상되며, 이의 사용으로 환경오염을 발생시키고 있는 현실에서 이에 대한 대안으로 대체에너지 개발과 적용의 필요성이 대두되고 있다. 이에 본고에서는 변전소에서 변압기 운전 시 발생되는 폐열을 냉, 난방에너지에 적용한 사례에 대하여 설명하고 이에 대한 경제적인 효과와 적용 가능성에 대하여 논 하고자 한다.

The output characteristics of solar cell are nonlinear, and these characteristics vary with load solar insolation. solar cell temperature. The PWM power inverter is realized by driving a inverter constructed with a high frequency buck-boost chopper in the discontinuous conduction mode(DCM). This paper present a buck-boost PWM inverter and its application for residential system.
