The purpose of this study is to analysis the change of rural house type and house plans in Bonghwa province. According to definition of rural area, the scopes of the research of rural houses limited the Bonghwa rural area(1 eup, 9 myeon). The method of study is to compare and analyze about housing situation, structure of house, housing type and construction of house space etc. through the statistical data of Bongwha statistical yearbook, space syntax(convex analysis) and other various data etc. during these 10 years. As a results of the analysis 1) According to Change of family member the supply ratio of detached house is steadily decreasing and changing from a detached house to multi-household house in Bongwha areas. 2) Most of houses structure were using lightweight steel construction because of cost-cutting of construction and easy way to construct etc.. 3) The highest Integration space is living space in rural house plans 4) The highest segregation space is bathroom space of master bed room in rural house plans. Some of bed rooms are classed as segregation space regardless of Integration space 5) Traditional front yard's function is changing from the place with the various functions to the place with the specific functions.

Indoor space becomes limited by each factor engirdling and defining infinite empty space. Those factors appear as physical ones called wall, floor, and ceiling, and earn existential value as a living space by placing furniture in the space organized in this way. However, it is not easy to find a clear harmony between the space and furniture. Since long ago, a great deal of effort has been put into creating a relational harmony between the space and furniture. This study is to be unfolded by assuming that spatial furniture comes amid these efforts. Namely, furniture does not exist as a separate entity in a space but interacts with the construction; thus, furniture is immersed into construction or construction becomes furniture, which demonstrates that furniture is on the continuum of the composition of the space. This study looks into the characteristics of spatial furniture in contemporary indoor space through relevant cases, and prepares the ground for a creative interpretation of Indoor space.

초고층건축물의 수요가 증가하고 수요지역이 확장함에 따라 초고층건설 기술력향상의 필요성이 증가하고 있다. 또한, 건물의 초고층화로 인해 마감공사는 프로젝트전체에 영향을 미치는 중요한 관리요소가 되고 있다. 이에 본 연구는 마감공사 준비작업의 의사결정 및 수행을 지원하기 위한 도구로서 현장사진기반 공간모델을 제안하고 있으며, 그 구축방법을 제시하고 활용방안을 모색하고자 하였다. 현장사진기반 공간모델을 통하여 초고층프로젝트의 특성과 공종에 맞는 공간모델을 활용이 가능할 것으로 예상되며, 이를 통하여 건설분야에서의 공간모델 실용화를 기대할 수 있을 것이다.

최근 대도심지를 중심으로 지반침하, 지반함몰 등 지하공간에서의 안전사고가 빈번히 발생하고 있다. 이에 정부차원에서의 다양한 대응방안을 마련하고 있으며, 이의 일환으로 지하공간통합지도 구축을 추진 중에 있다. 3차원 지반정보는 지하공간통합지도의 핵심 구성요소이며, "지하안전관리에 관한 특별법"에 따라 의무화된 지하안전영향평가의 주요 데이터로 활용된다. 3차원 지반정보의 구축 방법은 지하공간통합지도 구축 기본계획 수립 시 도출되고 국토지반정보 통합DB센터에서 지속적인 구축을 추진하고 있으나, 정확성, 효율성, 활용성을 고려한 구체적인 방안 도출이 필요한 실정이다. 본 연구에서는 지하안전관리 지원을 위해 3차원 지반정보의 정확성, 활용성, 구축 효율성을 고려한 구축 방안을 도출하고자 하였다. 이를 위해 국토지반정보 포털시스템에서 보유한 시추정보와 지반정보 구축 소프트웨어인 MVS, MakeJiban을 활용하여 표고와 지층 기반의 구축 높이 정확도를 비교하였다. 종합적인 분석결과 정확성, 활용성, 효율성 측면에서 원표고 기반의 전체 지층 일괄 구축이 가장 적합한 것으로 판단되었다. 향후, 본 연구결과를 바탕으로 일괄성 있는 3차원 지반정보 구축을 추진할 계획이다.

Since the twentieth century, common exhibitions have experienced display replacements and apace alterations. As a result, not only the visual space background of the spectators but the structure systems and positions of the construction space have also been changed. With regards to common zones of the exhibition space, appropriate harmonization of spectators space, aisle space, and media space are closely related the effectiveness and propriety of display arrangement. A number of preceeding researches suggest exhibition first, construction next, regarding the order of the construction and exhibition of the museums and art galleries. However, a majority of the exhibition hall constructions in Korea have not been carried away based on these models. Thus, disharmony of constructions and exhibition space structures have caused numerous problems. The purpose of this research is to seek the countermeasures that can be used in the stage of planning for the museum constructions and exhibition space by suggesting, based on the above mentioned points, the development of the indicators and analyzing methods to understand the structural attributes of the common exhibition space through space syntax method and multivariate analysis.

Greeting the era that the interest in qualitative aspects of life environment is getting important, commercial space, which is sensitive to the reflection of consumers' desire, is making efforts to secure the interior image identity of its own space. Especially, because the bar, which is the object of this study, is competing with undistinguished alcoholic beverages, the distinction of the interior image construction becomes more important. Here this study is purposed to understand the features of structural elements for the construction of the image identity of interior space. Especially, the purpose is to present the basic materials of the space design for individuality and distinction by considering relationship between the whole image and structural elements that form the image of space, and the preference, centering on the installation, which is being used very much for the image identity construction in eating and drinking space these days.

A fundamental problem is to construct linear systems with given transfer functions. This problem has a well known solution for unitary linear systems whose state spaces and coefficient spaces are Hilbert spaces. The solution is due independently to B. Sz.-Nagy and C. Foias [15] and to L. de Branges and J. Ball and N. Cohen [4]. Such a linear system is essentially uniquely determined by its transfer function. The de Branges-Rovnyak construction makes use of the theory of square summable power series with coefficients in a Hilbert space. The construction also applies when the coefficient space is a Krein space [7].

U-City related researches and development have been actively conducted in Korea since 2002. According to the Act on Ubiquitous City Construction, "U-City" is defined as "the city to provide ubiquitous service anytime anywhere through the existing ubiquitous backbone systems and ubiquitous technologies, ultimately for the purpose of improving urban competitiveness and quality of life. This research explains the plan to develop collective management technology for integrated operation of U-Space which makes up U-City. Specifically, this report is intended to suggest basic approach of identifying collective management elements of each U-Space type, developing integrated management system and creating interface module to link the system with urban integrated operation center.

This research is comprised of virtually simulating behavior while experiencing low gravity effects in advance of real world testing in low gravity aboard Zero Gravity Corporation's (Zero-G) research aircraft (727-200F). The experiment simulated a drill rig penetrating a regolith simulant. Regolith is a layer of loose, heterogeneous superficial deposits covering solid rock on surfaces of the Earth' moon, asteroids and Mars. The behavior and propagation of space debris when drilled in low gravity was tested through simulations and visualization in a leading dynamic simulation software as well as discrete element modeling software and in preparation for comparing to real world results from flying the experiment aboard Zero-G. The study of outer space regolith could lead to deeper scientific knowledge of extra-terrestrial surfaces, which could lead us to breakthroughs with respect to space mining or in-situ resource utilization (ISRU). These studies aimed to test and evaluate the drilling process in low to zero gravity environments and to determine static stress analysis on the drill when tested in low gravity environments. These tests and simulations were conducted by a team from Texas A&M University's Department of Construction Science, the United States Air Force Academy's Department of Astronautical Engineering, and Crow Industries
