Residental photovoltaic power system achieved remarkable results in distribution and activation through 'One Million Green Homes Program' led by the government. However, system maintenance and management after installation are relative unsatisfactory. Thus, problems, such as malfunctioning, decrease in efficiency, breakage, etc, are occurring in succession which means that expensive facilities are not used effectively. This study attempted to propose a more preferred alternative to the photovoltaic power system currently applied and installed to the housing by investigating and analyzing the said system, identifying management practices, and deriving problems. For this study, 48 houses equipped with photovoltaic systems in J City were chosen and they were analyzed after preliminary research and field investigation. The results revealed that most of the surveyed systems in J City are still in fairly good conditions. But the instruction and information regarding the appropriate operational management of those surveyed systems have not been delivered to the owner. Therefore, promotion education and related manual deployment should be done by the contractor. In terms of installation, inadequate system location and some warranty services are required to be improved, which are usually caused by a lack of careful planning and construction. In addition, the follow-up management needs to be provided about five years later after installation considering system deterioration.

According to "The regulations regarding the residential construction standards", residents' common spaces are restricted by the standards on building facilities. In a typical apartment complex, residents' communal facilities are represented by a children's playground, a elderly social station, and a management office. However, these residents' communal facilities do not reflect residents' composition characteristics. Multidisciplinary research and experimentation to enable the community of housing complex are being actively conducted. In these situation, we observed institutional improvement about installing standard of community space, and analysed the tendency. The purpose of this study is to propose practical institutions to review the institutional improvement. We conducted a case study where was renovated the community space according to the new standard. As a results, the installing standard of the community space has changed in the direction to increase the autonomy of resident. These results raise the practical performance of the community space, and it has the effect of increasing the satisfaction of the residential environment. The results of this study suggest an alternative to the institutional aspects and planning aspects for community activation in housing complex.

An increasing interest towards the investigations of chalcogenide glasses has been observed in the past years. This interest is due to their specific properties, as well as to the possibilities for their application in different fields of science. The optical devices, working on the basis of photoinduced phase transition between amorphous and crystalline state in the chalcogenide glasses, are a perspective for the micro- and nano-electronics. Here we were analysis basic physical properties for Ge-As-Se and As-Se chalcogenide glasses samples for characteristic for a planning of chalcogenide aspheric lens. From differential DTA/TG results, activation energies of the crystallizations of $Ge_{10}As_{40}Se_{50}$ and $As_{40}Se_{60}$ were approximately 3.6 eV and 3.3 eV, respectively.

Activated carbon is carbon produced from carbonaceous source materials, such as coconut shells, coals, and woods. In this study, an activated carbon production system was analyzed by carbonization and activation in terms of environmental impact and human health. The feedstock of wood wastes for the system reduced fossil fuel consumption and disposal costs. Life cycle assessment methodology was used to analyze the environmental impacts of the system, and the functional unit was one tonne of wood wastes. The boundary expansion method was applied to analyze the wood waste recycling process for activated carbon production. An environmental credit was quantified by avoided impact analysis. Specifically, greenhouse gases discharged from 1 kg of activated carbon production system by feeding wood wastes were evaluated. We found that this system reduced global warming potential of approximately $9.69E+00kg\;CO_2-eq$. compared to the process using coals. The environmental benefits for activated carbon production from wood wastes were analyzed in contrast to other disposal methods. The results showed that the activated carbon system using one tonne of wood wastes has an environmental benefit of $163kg\;CO_2-eq$. for reducing global warming potential in comparison with the same amount of wood wastes disposal by landfilling.

This study starts from the architectural and urban interest to integrate the daily life and behavior of residents in the city of Seongnam and to sustain the community. A fixed abode is something that can not be separated from the place and should be approached from a comprehensive perspective reflecting the physical and social conditions of the region. Although residential neighborhoods have a residential walking range, which has a steep slope, it has been formed in the suburbs of the residential area where commercial facilities are activated organically. The humanities and social organizations of the residents are integrated with the physical space and act as constituent factors of major cities. This is an attempt to suggest improvement and activation of existing cities based on their daily lives, rather than destroying cities and creating new ones. Also, it is proposed to 'Neighborhood Street' as an indicator of a uniform urban renewal plan for existing urban regeneration projects. Based on the definition of the city of living in the city, the center of the city will be located in the center of the city, and it will be the center of the city's bustling streets.

Recently, residents' community center is trying to combine with various program and facilities as the residents self-government program's development. This is due to the reduction of administrative tasks, the computerization of programs, the importance of community participation activities, the activation of community, and the increase of welfare projects. Therefore, previous studies on program complexity have been actively carried out. Nevertheless, spaces and programs studies of considering regional characteristics are lacking. Therefore, the community centers' program and spaces need to change. Therefore, this study propose an improvement direction through analyzing the situation of the residents' community center. For this study, the precedent research and institutional limitations are examined. In addition, this study selected and analyzed the 15 local community center. Thirdly, interviews were conducted with users and officials of the 5 residents' community centers on major changes. Finally, This study suggests direction of program improvement and architectural design direction. As a result of this study, integrated management measures with overlapping agencies should be sought. Surplus space will have to be rearranged into a new program through prior examination. Above all, the proposed remodeling guidelines require user requirements to be reflected and designed with the residents.
