Recently, the apartment building has been constructed in large quantities to provide housings due to the gravitation of population towards large cities. However, we're faced with a critical problem of deterioration of our dwelling environment caused by the trend toward high-rise apartment which could be an obstruction in obtaining sufficient sunlight. Therefore, there have been several legislative actions against infringement on the right of sunshine. In the building law, sunshine hours and the minimal separated distance between apartments are regulated as the criteria for the site planning, However, the minimal separated distance was defined without consideration of the parameters like building orientation and thermal effect of the sunshine hours in the site planning for the apartment building. In this study, the sunshine hours and heating energy during the underheated season for various arrangements in site planning are carefully considered and analyzed.

Recently, the interest on the comfortable dwelling environment is increasing and the effort to solve the problem of exterior noise was tried. The propose of this study is to suggest the design of balcony window in apartment and to evaluate the sound insulation of it. So, we designed five types of balcony window which were considered not only sound insulation but ventilation. The sound reduction index of window was evaluated by the measurement in mock-up room. The results showed that case 2 improved about 6dB in the weighted apparent sound reduction index than case 1, and case 3 reduced about 39% in construction cost than case 4.

The loss of connectivity and fragmentation of forest landscapes are seriously hindering dispersal of many forest-dwelling species, which may be critical for their viability and conservation by decreasing habitat area and increasing distance among habitats. For understanding their environmental impacts, numerous spatial models exist to measure landscape connectivity. However, general relationships between functional connectivity and landscape structure are lacking, there is a need to develop landscape metrics that more accurately measure landscape connectivity in whole landscape and individual patches. We reviewed functional and structural definition of landscape connectivity, explained their mathematical connotations, and applied representative 13 indices in 3 districts of Seoul having fragmented forest patches with tits, the threshold distance was applied 500m by considering the dispersal of tits. Results of correlation and principal component analysis showed that connectivity indices could be divided by measurement methods whether they contain the area attribute with distance or not. Betweenness centrality(BC), a representative index measuring distance and distribution among patches, appreciated highly stepping stone forest patches, and difference of probability of connectivity(dPC), an index measuring including area information, estimated integrated connectivity of patches. Therefore, for evaluating landscape connectivity, it is need to consider not only general information of a region and species' characteristics but also various measuring methods of landscape connectivity.

As the elderly population increases, concerns for the elderly's welfare become greater both quantitatively and qualitatively. In order to give a chance for the elderly to live in familiar dwelling and regional context to which they are accustomed, and to participate in their society actively, it is of great importance that suitable living spaces must be provided for the elderly. The practical ways of providing people with good living environment and its easy maintenance for healthy and valuable lives were discussed in this paper. This research is designed to propose pertinent policies related to social issues concerning the elderly. 137 seniors over 60 living in Gwanaju city were sampled and surveyed. The scope of planning for the elderly's lifestyle and welfare is divided into two parts, one is planning of space for the realization of stable and spacious dwellings and another is urban environment planning capable of supporting healthy and affluent lifestyles. Also, the realization of stable housing, the construction of urban structure for a healthy life, and the provision of barrier-free living conditions are investigated. For increasing the degree of stabilization and improvement for the elderly's life, self-governing bodies should grasp the demands of living condition and spatial requirements by taking the lifestyles of the elderly into account in urban or regional levels. Then, a master plan including development, improvement, execution, and maintenance of proper housing facilities and urban environments should be made for the best results.

This study researches the dwelling satisfaction about apartment remodeling by inspecting ten apartments located in Gwang-Ju, Jun-Nam province. The method of study is to use the field study method, which is based on cultural anthropology, and the participant observation method at same time. According to the research, we find those things as they follow. First, the participation of residents and the mutual agreement are necessary in the process of the selecting a company. Furthermore it's hard to solve the problem about an uniform design and an inferior construction. These things are the most serious factor in dissatisfaction of resident environment. Second, the space of storage and veranda should be separated for the proper functions and the space for laundry is necessary. The rooms, except bedroom, and the bathroom in the main living room should be used for practical application because they are not used so often and if we make the veranda as a inner space, we've got to make a gardening plan, too. Through this research we find out that the participation of an expert company and residents for enough communication and mutual agreement and the space plan for the satisfaction of occupants are necessary for the proper apartment remodeling.

Our country has depended on fossil fuel very much according to the Increasing of the demand of the electric power. For instance, if the reduction and freezing caused by the warm gas in earth by the regulation of international environment happen in Korea it will bring about the result of weakness in industrial activity. As a result, it will cause many problems to compete an advanced country which wants to connect environment with the activity of industrial product in their country. The photovoltaic system outputs have peak about a half past 13 o'clock(before and after) mainly in a good weather. The output decreases rapidly from a half past 17 o'clock and PV output doesn't work at six o'clock before the sun rises. The outputs of PV system stops at that time. The frequent degree of harmonics in dwelling house which lots of people live has peak from 19 o'clock to 22 o'clock Harmonics mainly happens at least at night. In recent, many researches about power quality has been studying very hard in order to solve the question, the voltage fluctuating and harmonics as one compensator. In this paper, I suggest the algorithm which can increase the power quality as a rate of operation of this system. This algorithm proves to have effectiveness through computer simulation.

The rapid urbanization after 1970s caused the shortage of dwellings in urban areas. As the result, the underground dwellings were developed to compensate for the insufficient dwelling spaces. While the underground dwellings have some advantage in the respect of thermal and acoustic environment, they usually have the basic problems in the indoor air quality because of the lack of natural ventilation through small window areas. The purpose of this study is to investigate and to improve the indoor air quality of underground dwellings. Thirty Units in Seoul and Gyung-Gi Province were investigated into the indoor environmental conditions. For the purpose of the improvement of their indoor air quality, Automatically-operated ventilating fan was installed in a sample unit which has worst indoor environmental condition. Then the indoor air quality was monitored when it was operated by $CO_2$ control system and timer. Finally economic feasibility study was made considering the effect of the improvement of indoor air quality. The extra cost for installing timer could be paid back only in 10 months, so timer-installed automatic fan is recommended to improve the indoor air quality of underground dwellings.

Eco-village is emerging as one of housing styles in the modern age. The common space in Eco-village uses environment-friendly materials while residents appear to aspire to a community. The common space in Eco-village offers a place of interchange and interaction for both visitors and residents as a transit area connecting dwelling units. It also forms the sense of community and serves as a space that builds friendly relations among residents. However, there seems to be a lack of research compare to its various roles and importance for this common space, which is an significant factor in establishing Eco-village plans. The purpose of this study is to provide research data by creating a layout drawing of Eco-village and reveal the characteristics of space boundary and practical use of common space through case studies on villages. This will serve as actual data in designing common space which would correspond to the purpose of Eco-village planning.
