본 연구는 동래 읍성의 입지, 성곽 형태 및 도로망. 관아 및 가옥분포 토지이용 등을 중심으로 조선시대의 경관 복원을 시도한 후. 일제강점기에 나타난 변화를 파악하여 이를 사회ㆍ문화적인 측면에서 설명하고자 하였다. 가야시대부터 취락이 형성되었던 현재의 장소에 고려말 읍성이 이전 입지한 것은 해안방어 요충지와의 접근성을 최대로 하기 위하였던 것으로 추정된다. 이후 읍성이 위치한 장소는 동래부의 중심 공간으로 등장하였다. 이와 같은 입지 특성은 4대문 위치 및 성안의 도로망 분포 등에 영향을 주었다. 관아시설의 배치는 중앙 권력의 상징. 읍성 군사 방어 기능과 관련되어 배치되었다. 객사 입지는 중심공간에 지형을 이용하여 권력 질서의 위계를 반영하였으며. 좌측에 동헌. 우측에 향청 및 군사 기능이 배치되었다. 읍성내 취락은 남문을 중심으로 분포하였고. 산록부는 농경지로 이용되었다. 일제 강점기 중 1920년대 시행된 시구개정사업으로 성벽이 철거되었고, 성안에 격자상의 도로망이 신설되었다. 평지에 있던 성벽 자리는 도로용지나 주택지로 이용되었다. 객사와 동헌을 중심으로 형성되었던 성안의 공간구조가 변화되었고. 관아건물은 공공기관으로 사용되거나, 민간인에게 불하되어 다른 용도로 이용되었다. 이 과정을 통하여 읍성이 위치하였던 장소의 상징적 의미는 쇠퇴되었다. 그러나 현대사회에서 읍성은 부산시민에게 역사적인 중심공간으로 자리잡고 있으며. 현재 남아 있는 일부 경관을 중심으로 복원작업이 시도되고 있다. 연구 결과는 읍성이 단순히 건축물이 아닌 당시대의 사회문화가 투영된 경관이며, 각지방에 소재한 읍성은 새로운 시각으로서 재조명되어야 할 것임을 보여준다.

This study was designed to examine the meaning of housing in modern Korea, and to draw the interrelationship of people and housing. In-depth interviews were conducted, and the qualitative research investigated various aspects of housing history among four individuals during the different phases of social and economic transitions. Each narratives showed the unique characteristics of life history, and the conceptual frameworks for interpretation were microsociological approach by Morris and Winter(1978) and pathway approach by Clapham(2005). One narrater named "K" had gone through various housing experiences since her birth in 1933 at a traditional Korean housing, and she moved to a traditional rural community. Another narrater called "S" was born in housing built during the Japanese colonization, gained wealth through the housing boom of the industrialization, and has lived in a suburban condominium. "G" spent her entire life in an urban area, had never owned a house, and lived in a house with poor quality. The other narrater named "L" had lived in a single-family home with a large yard since her childhood, and she has resided in multi-family housing by herself after having a lot of experiences of building houses. The results revealed that housing could play as a simple role as a shelter, be transformed over family life cycle, become prestige of extended family, social and family status, investment. Meaning of housing from the pathway approach were closely related to hometown, the relation to birth family at postmarriage, economic status, and housing experiences according to the social change. As a conclusion, the meaning of housing is vary, and housing conveys numerous implications including psychological, social and economic aspects.

Since 'Hanok Expanse Support' has been started in Seoul, its target was expanded from renovation to new construction and from 'Hanok District' to all area in Seoul. The newly built hanok with Hanok Expanse Support had to follow the standards about the form of the hanok and adapt to modern lifestyle. However, the newly built hanok were planned with 'kan' since it retained the traditional wooden structure. So their composition of kan were considered to be influenced by the standards of each district and modern lifestyle. Therefore the aim of this study is to understand the architectural characteristics of newly built hanok in Seoul since 2000 focusing on the kan composition. Because of the differences in site conditions and the district unit plan, newly built hanok in Hanok District have more limited changes than Other District. However, kan is composed variously in horizontal and vertical ways to make the most space according to site conditions and most of the newly built hanok have opened courtyard rather than closed courtyard layout. With kan composition in various directions and kan added under the eaves, kan is highlighted in form. On the other hand, the composition of kan as an interior spatial element has changed and weakened because the lifestyle has changed compared to the traditional hanok and the 20th century urban hanok. Also the regular kan composition of Mom-chae and Nalgae-chae has changed. And kan is divided regardless to the wooden structure. Also, with the added kan under the eaves the main kan is dismantled inside. This paper indicates that although there is an undeniable premise that the case is restricted to hanok received Hanok Expanse Support on the condition of following the standards of the form of hanok, it is a part of the transitional changes that hanok is experiencing.

Focusing on the creation of a new han ok, especially a mid-rise hybrid-structured Han-ok, this study proposes a middle-rise (four-story) Han-ok on one and two lots located in Seoun-dong, the existing Han-ok intensive housing site in downtown Cheongju. 1) In terms of layout and function, according to the existing L-shaped Han-ok corresponding to the road and the direction, the parking lots and shops on the 1st floor, the business facility on the 2nd floor, the Han-ok on the 3rd and 4th floors are placed. There are yards, open roof yards, and semi-open Daecheong(大廳, main hall), which can be shared by residents. 2) In terms of structure and form, one or two floors (some 3 floors) are 5.4m square and 5.4×6.6m modules of the RC(Reinforced Concrete) group, and the upper floor reflects the 2.7m module, size and shape of the existing Han-ok. By extending the outer wall of the RC group in the lower floors (1st to 3rd floors) to the wooden exterior of the upper floors (2nd to 4th floors), it is attempted to avoid the awkward appearance of the RC group being exposed to wooden structures. And it is also attempted to reflect the wooden shape and design elements through the elevation elements such as horizontal windows, corner windows, picture frames, and vertical slits. 3) In environmental control and facilities, it is attempted to smooth the ventilation of the building by forming a vertical upward airflow from the dark space of the low floor to the positive of the upper floor. This doubles the effect through a vertical rise of cold air generated in a narrow alleyway, piloti parking lot, and the various voids. In addition to the Daecheong and Numaru(loft) of Han ok, the rooftop yard, the terrace, and the balcony, horizontal natural ventilation is generated through divided doors and transom windows.

China's Mapping Satellite-1, developed by the China Aerospace Science and Technology Corporation (CASC), was launched in three years ago. The data from Mapping Satellite-1 are able to use for efficient surveying and geometric mapping application field. In this paper, we fuse the panchromatic and multispectral images of Changchun area, which are obtained from the Mapping Satellite-1, the one that is the Chinese first transmission-type three-dimensional mapping satellite. The four traditional image fusion methods, which are HPF, Mod.IHS, Panshar and wavelet transform, were used to approach for effectively fusing Mapping Satellite-1 remote sensing data. Subsequently we assess the results with some commonly used methods, which are known a subjective qualitative evaluation and quantitative statistical analysis approach. Consequently, we found that the wavelet transform remote sensing image fusion is the optimal in the degree of distortion, the ability of performance of details and image information availability among four methods. To further understand the optimal methods to fuse Mapping Satellite-1 images, an additional study is necessary.

Buildings are responsible of major energy consumption globally. In addition, they are linked to thermal comfort. The need to provide comfort becomes more crucial in schools as they are the place where students learn, and develop their skills. This research aims to investigate the energy responsiveness of new and traditional school building design, where major variation in form, amount of external walls and glazing are different. The research focused on indoor microclimate condition of selected schools in the city of Jeddah where the climate is hot and humid using advanced tools for monitoring. The research uses advanced energy equipment to measure several aspects such as floor temperature, roof temperature, globe temperature and other factors which can lead to predictable thermal comfort of users. The findings suggest that a larger area of glazing shielded from sunlight has a greater influence on both indoor condition and general thermal sensation. The finding also suggests that the glazing ratio is a major contributor on indoor thermal pattern which can result in an increase in temperature profile between from $7-10^{\circ}C$. The findings of this research can assist in the improvement in the design of the prototype school building in hot and humid climate.

The traditional farming method has very long history in the process of agricultural development. The application of chemical fertilizers production became most popular to increase quantities of agricultural production. The United States of America is one of largest countries in the world. There are at present 50 States and farming conditions are very different from each individual States. There are increasing trend of agricultural production by applying chemical fertilizers as well as sprays during last 50 years(1940-90). The disadvantages of conventional farming method were to destroy nature and human life. There were some other kinds of disadvantages such as nitriated contamination in drinking water both for human being and animals. The alternative farming method is one of new farming method reducing and/of non-application of chemical fertilizers and sprays in agricultural production. There is less economic research on alternative farming system about $5.444 economic advatages in organic farms comparing commercial farms at the same area. There are advantage of higher unit price level in orgnic products, decreasing chemical costs as well as effect of crop combinations. It is certainly necessary to have more empirical research on economic and management of alternative farming method in the United States of America. However, if there is economic advantage in alternative farming methods, the future development possibility of alternative farming method can be very bright in vear future. There might be more advantages such as soil conservation, better quality of agricultural products, better health conditions of farmer's and consumer's as well as keeping healthy environment of rural and urban areas.
