In this study, an analytic hierarchy process (AHP) was conducted with the aim of developing a post-disaster refugee housing performance index system (PPS) to improve the post-disaster refugee housing (PRH) performance criteria for the foundation of quality-based development. The PRH was defined as a mid-term temporary housing facility that is used for a certain period before the permanent housing is established. The safety, rapidity, reusability, habitability, and economy were derived from major performance factors through prior research. A hierarchical PPS was organized by linking the major performance factors with the whole life cycle process of PRH. The priority of each performance index of PPS was determined quantitatively using the analytic hierarchy process through an expert survey. Based on AHP analysis, the performance criterion of the total weight 1-10 ranking and the performance criterion of the first rank in each category were classified into the essential performance criterion (must be achieved) and the others were classified into the recommended performance criterion (optional achieved) and the performance index was constructed considering all stages of PRH development. With the completion of the PRH performance index, it is expected that victims will be able to secure stable residence and return to their daily lives quickly.

This research starts from the questioning of current housing development on the hilly site in Korea. It aims to investigate various design techniques of low-rise housing as an alternative housing plan on hilly sites. Several generic solutions of the combination of building type and road pattern are tested for a simulation process, and evaluated in terms of crucial design issues; development density, parking space and open space. As a result, four reasonable models are selected for making full use of geographical features of hilly site, two models each land slope of $18^{\circ}$ and $26^{\circ}$. Several design techniques for each model are also suggested, in ensuring the development feasibility by considering land slope, vehicular access and parking, common open space, and community facilities.

The purpose of this study is to provide the guidelines for housing area that consider the children's outdoor behavior. This study was complemented the limit of study method of the previous studies limiting the subject to play space in APT. So, this study was progressed the analyzation of physical characters of outdoor spaces, the observation of children's activities behavior, and the survey of children's opinion and satisfaction. Especially, 2 objective housing areas of this study were selected the deferent areas. The deferents were the structure of street, the location shape of parks, and the physical characters(accessibility, network etc.). Finally, founding on the result of this study, the 7 guidelines of housing area for children were presented : play space, park & green space, space of around the education facilities, space of around the commercial facilities, street space, square, and parking lot. This study have means that expand the objective range and use the variety study methods.

Based upon the research and analysis on the downtown residents' satisfaction with their current housing areas and preference for future housing areas, this study clarifies the following. First, the breakdown on various factors influencing the housing environment indicates that downtown residents are the most satisfied with the easy access to the public transportation, and cultural and commercial facilities. Second, they are not content with the amenity aspects such as the air, noise, and the surrounding views, and the economic aspects such as the prices of the houses and the prospects for future investment. The low satisfaction suggests that the amenity aspects and economic aspects should be considered for future downtown housing development. Third, more than half of the residents in downtown areas still prefer to dwell in downtown areas. In the future downtown development, the close analysis on the characteristics of downtown dwelling, and the researches on the right direction of downtown housing development for the whole citizens of Daegu should be done in advance. Last, the majority of people wishing to reside in downtown want medium- or large-scale apartment complexes. In the future downtown housing development, it should be focused on the downtown residence with complex functions rather than on the small-scale maintenance projects.

The purpose of this study is to find the characteristics of space utilization and the problems that follows after converting in a new developmental residential area. This study used the content-analysis method and analysis was made on the floor plans for 95 different conversion cases. Above all, 190 unit plans (the unit plans for conversion before and after) were analyzed. The results of this study were as follows; 1) There were 8 types of conversion according to such usages as residential, commercial and residential-commercial buildings. 2) In the case of conversions, from residential to commercial, there was a tendency each floor was integrated to exclusive use for commercial or commercial with small portions of residential usage. And in the case of conversions from commercial to residential, there was a tendency that all space of each floor were changed to exclusive usages for residential purposes. 3) In case of usage conversion from commercial to residential, there were constraints for balcony installation, because of its original lot-structure and building equipments. Also, when the basement was converted for residential purpose, there was no possibility for an extra lighting or ways to ventilate the area.

악취는 인간이 직접 후각으로 느끼는 환경오염의 지표로서 극히 낮은 농도에서도 피해를 유발하여 대기질 전반에 대한 불신을 초래하게 된다. 악취의 주요 발생원으로는 정유공장, 화학공장, 하수처리장, 분뇨 및 축산폐수처리장, 쓰레기 매립지 등으로 발생원이 매우 다양하고 여러 가지 복합된 화합물이 원인이 되어 악취를 유발시키는 것이 특징이다. 우리나라의 주거여건은 주변환경을 충분히 고려하지 못한 개발로 공업지역과 주거지역이 근접 또는 혼재하여 악취오염에 근본적으로 취약한 구조의 도시가 형성된 곳도 있다. (중략)

The key technology for developing high quality LCDs is about manufacturing BLUs with homogeneous dot distributions. Commonly, homogeneous dot distributions are obtained by the halftoning methods which convert a gray-scale image to a binary image. Among many halftoning algorithms, the error-diffusion technique based on the principle distance is known to show homogeneous dot distributions. However, this technique has a drawback; the extent of the principle distance at each pixel with respect to those of the neighboring pixels can be too small or big creating a gap or overlap. In this paper, we propose a new error diffusion algorithm based on the variable principle distance which improves the existing error diffusion technique based on the principle distance. The variable principle distance at a given pixel is calculated with gray-scale values of the pixel and its neighbors and thus the principle distance value is variable depending on the direction from that pixel. This variable principle distance technique helps BLUs obtain homogeneous dot distributions.

The purpose of this study is to analyze the effects of geographic and Feng Shui characteristics of Gwanggyo New City on residential satisfaction and whether residential value has a significant medium effect. It is meaningful to present theoretical, institutional, and practical implications of this research as basic data. According to the results of our analysis of questionnaires completed by residents of Gwanggyo New City, geographic and Feng Shui characteristics showed a significant positive effect on residential value and satisfaction and a significant mediating effect on residential value. Rather than professional Feng Shui factors, general geographical factors have a relatively larger influence on residential value and residential satisfaction, identified as a more significant factor for ordinary residents. Study findings are valuable as basic data in order to suggest institutional and practical implications for policy design to develop cities and improve residential satisfaction.
