  • The artillery fire accident in Yeonpyeong Island showed that the man-made disaster caused by the domestic political conditions as well as the conventional natural disaster can occur in Korea. Especially, it can be known that the whole community can be abandoned despite of a small scale of practical damage in residential district and the resulting large scale of refugees can be produced in the nation. This study investigated the real condition of temporary housing which has been provided at the Island. Firstly, in the theoretical review based on the literature study, the content on the background of temporary housing, the providing procedure of its concept, the status of supply, etc. has been considered. And it researched the current condition of the entire temporary housing through the questionnaire and interviews targeting the residents in the Island. So it purposed to make use of the results as a plan and design for future temporary housing against disaster.

  • Recently the architectural paradigm have been changing into eco-friendly architecture as an sustainable architecture. This social background encourages the development of various methods of building applicable for eco-friendly buildings in architectural design. Among them, passive architecture is an design approach for eco-friendly design that contrasts with technology-based methods through MEP for renewable energy. This study researches the Passive Architectural Design methodology with two points of view; Passive Architectural Design Techniques as a guideline, which defines the elements to consider for passive architecture, and the project of Sejong Municipal Public Library as a case, which is to analysis the architectural design process. The purpose of this study is to propose an eco-friendly public building based on the methodology which is suitable for passive architectural design. Finally, this study suggests that the eco-friendly public building design for passive architecture should consider from the early step of design process, such as concept and building form etc. What is important for the passive architecture is not how much building can produce the natural energy but how less building consumes it to maintain.

  • Recently, as the continuously increasing of the one-person households, builders were focusing on a built-in furniture development for efficiency. Through the dead space of the space can be reduced. Also, Condensation that occurs in a built-in furnitures installation space may result in different results depending on the room's direction, floor, finish, adjacent room effect, occupant's lifestyle. In this background, it can be considered in terms of functional aspect and morphological aspect by using WUFI2D simulation system. As a result, the tendency of occurrence of condensation was examined by comparing the water content and the growth potential of fungus graph which came from WUFI2D. Results of this study are as followings: Built-in furniture, both top & bottom open, is more stable to condensation than the built-in furniture with the top or bottom open. Also, Among from the top floor built-in furniture to the bottom of it, the bottom one is more stable to condensation.

  • Recently, the prediction of wind environment around a building using Computational Fluid Dynamics (CFD) technique comes to be carried out at the practical design stage. However, there have been very few studies which examined the accuracy of CFD prediction of flow around a high-rise building including the velocity distribution at pedestrian level. The working group for CFD prediction of wind environment around building, which consists of researchers from several universities and private companies, was organized in the Architectural Institute of Japan (AIJ) considering such a background. At the first stage of the project, the working group planned to carry out the cross comparison of CFD results of flow around a high rise building by various numerical methods, in order to clarify the major factors which affect prediction accuracy. This paper presents the results of this comparison.

  • This study is to inspect and analyse the historical background, spacial organization and architectural features about the traditional government office building of Gangwon Gamyoung(the supreme local government office of Gangwondo in Chosun dynasty). The results are as follows. - Gangwon Gamyoung was located at the center of Gangwondo in consideration of distance to each small local office. And also it was located in consideration of geographical connection between Hanseong(today's Seoul). - The spatial organization of Gamyoung was divided into the three parts of entrance space, government office building space and backyard space. The entrance space was composed of three gates(Pojungru-Jungsammun-Naesammun). The government office building Space was consisted of business and living building as center of Sunhwadang(the main office building). And the backyard space was composed of Yonji(pond), Jungja(bower), and so on - The way to enter the space of Gamyoung follows the order from Pojungru(the first & outer main gate with a bower), Jungsammun(the second & intermediate gate), Naesammun(the third & inner gate) to Sunhwadang at last. - There were a beautiful Yonji(pond) which to be rectangular type and to have a round island with Bongraegak(bower) at Gamyoung backyard, the drain conduit and pedestrian road covered with pebble in the ground.

  • The purpose of this paper is to clarify the introduction of foreigner's architectural engineering such as building materials techniques engineers, focused on the Late Yi-dynasty. Such all kind of building materials as timber brick tile cement lime glass window furniture and so on was imported from the foreign company in opening period of ports in Cho-son. The timer of these materials was imported from Japan, the brick tile from China, and others directly from Western counteries indirectly from Japan China. As it was active in an inflow of building materials and machines about 1890's, the modern building techniques were introduced and elementarily mastered such as timber sewing, manufacturing baking of brick glass, and masonry, The above modern techniques became the direct background in the formation of Korean modern architecture. Building engineers can be divided into three classes : architect engineer apprentice. But It could be apparently not divided the relation between architect and engineer at that time. They could be classified into job-architects who were engaged by the Korean government and leaded an active life in their settlement, and missonaries, They introduced the construction and style of modern architecture in our country, And so many skilled laborers and laborers participated in the construction of their settlement.

  • Feature based stereo matching is an effective way to perform 3D building reconstruction. However, in urban scene, the cluttered background and various building structures may interfere with the performance of building reconstruction. In this paper, we propose a novel method to robustly reconstruct buildings on the basis of rectangle regions. Firstly, we propose a multi-scale linear feature detector to obtain the salient line segments on the object contours. Secondly, candidate rectangle regions are extracted from the salient line segments based on their local information. Thirdly, stereo matching is performed with the list of matching line segments, which are boundary edges of the corresponding rectangles from the left and right image. Experimental results demonstrate that the proposed method can achieve better accuracy on the reconstructed result than pixel-level stereo matching.
