  • In this study, a smart base isolation system has been proposed to reduce dynamic responses of a spacial structure subjected to seismic excitation. MR dampers and low damping elastomeric bearings were used to compose a smart base isolation system and its vibration control performance has been investigated compared to that of the optimally designed lead-rubber bearing (LRB) isolation system. Control performance of smart base isolation system depends on control algorithm. Fuzzy controller was used in this study to effectively control the spacial structure having a smart base isolation system. Dynamic responses of the spacial structure with isolation system is conflict with base drifts and thus these two responses are selected as objective functions to apply multi-objective genetic algorithm to optimization of fuzzy controller. Based on numerical simulation results, it has been shown that the smart base isolation system proposed in this study can drastically reduce base drifts and seismic responses of the example spacial structure in comparison with the optimally designed LRB isolation system.

  • The purpose of this study is to show the relation of the change between spacial structure and social conditions of rural area. The spacial structure change of Asan city was analyzed using Space Syntax, and multiple regression analysis (dependent variables: connectivity, global integration, local integration / independent variables: population, household, farm population, farm population of 65years old and over, farm household, part-time farm households, cultivated land) was accomplished. As th result, that the increase of connectivity is related to the increase of population and farm population of 65years old and over and the decrease of farm population, and the increase of local integration is related to the increase of farm population of 65years old and over was showed. However, that global integration is not related to change of social conditions was proved.

  • Retractable roof system is one of the special feature in stadium or complex structure. And this retractable roof system makes possible to use spacial structure all-weather. This retractable roof system is able to classified into overlapping, parallel movement and folding system. Moving load, impact load, inertial or braking loads, these dynamic loads induced by movements of retractable roof system. So it is necessary to analysis of spacial structures are subjected to these dynamic loads. Dynamic loads that are induced by the retractable roof movements can be applied to moving mass method or moving force method. But, moving force method is appropriate because the retractable roof movements is slow relatively. In this paper, new application method of moving forces induced by the retractable roof movements is proposed. And vibration analysis of spacial structures are executed by using the proposed method. This proposed equivalent moving force can be easily applied to spacial structure that is subjected to dynamic loads induced by movement of the retractable roof system.

  • A novel vibration control method for vibration reduction of a spacial structure subjected to earthquake excitation was proposed in this study. Generally, spatial structures have various vibration modes involving high-order modes and their natural frequencies are closely spaced. Therefore, in order to control these modes, a spatially distributed MTMDs (Multiple TMDs) method is proposed previously. MR (Magnetorheological) damper were used to enhance the control performance of the MTMDs. Accordingly, MSTMDs (Multiple Smart TMDs) were proposed in this study. An arch structure was used as an example structure because it has primary characteristics of spatial structures and it is a comparatively simple structure. MSTMDs were applied to the example arch structure and the seismic control performance were evaluated based on the numerical simulation. Fuzzy logic control algorithm (FLC) was used to generate command voltages sent for MSTMSs and the FLC was optimized by genetic algorithm. Based on the analytical results, it has been shown that the MSTMDs effectively decreased the dynamic responses of the arch structure subjected to earthquake loads.

  • This study is purposed to understand the spacial usage of the furniture in detail for interior architecture. Many documents have prescribed the spacial furniture at random. While modernist have been interested in the spacial usage of the furniture, the importance of the spacial furniture stands out in architectural space. Since long ago, a great deal of effort has been put into creating a relational harmony between the space and furniture. The villa, the weekend home of the Savoye family, was built between 1928 and 1931. Particularly, the villa Savoye was focused for this study. Le Corbusier viewed desks and case pieces for storage as architecture, and the unite furniture and architecture by developing cabinets in standard modules that could be painted either the wall color to become part of the wall or in contrasting colors to stand out as furniture. Spacial furniture was used architecturally in the interior as well, it gives the space an unexpected playfulness with the color of the finishing materials. The various usage of the Spacial furniture constitute an element of great architectural richness. They have a unique principle based on emotional order and make the man move to another space and experience the spacial connection. In particular, the furniture that was considered by Corbuisier have rational function, division of the space, leaning the structure, and so on. The furniture as the element of the space composition can change the architectural space and view as well as connecting each other. Spacial furniture appear as physical ones called wall, floor, column, and existential value as a living space.

  • The purpose of this study is to investigate the change of spacial structure from rural space to urban space and to examine the characteristic of spacial restructure, focusing on the Hwamyeong-Dong of Buk-gu in Busan. Hwamyeong-Dong has changed from rural area to urban area because of spacial expansion owing to industrialization and urbanization. The unique natural environment, rural village, etc. were disappeared and instead the apartment complex, commercial building, and so on were built. For this reason, historic and concrete place were vanished and so the spacial homogenization and uniformization were formed centering around apartment complex. But the singularity of Hwamyeong-Dong exposes in the way that unique history, custom and memory, trace of Hwamyeong-Dong preserved through the support and effort of the residents and that the Daechen stream changed to ecological stream. In addition, Hwamyeong-Dong altered heterogeneous, multi-layered urban space from homogeneous rural space in terms of the apartment supply sectors and scale, the distribution and kind of commercial facility, residents's composition. This has brought about the subdivision, hierarchization of the space as well as the residence, education, culture. Especially, Hwamyeong3-Dong that built to large scale apartment complex are significantly different from Hwamyeong2-Dong. Hwamyeong2-Dong is marginalizing step by step. However, It is found that the residents in Hwamyeong2-Dong are making an effort for liveable place with ecological residential community and educational cultural community as the center.

  • This paper presents an efficient FTL for NAND flash based SSDs. Address translation information of page mapping based FTLs is stored on flash memory pages and address translation cache keeps frequently accessed entries. The proposed FTL of this paper reduces response time by considering both of temporal and spacial localities of page access patterns in translation cache management. The localities of several well-known traces are evaluated and determine the structure of the cache for high hit ratio. A simulation with several well-known traces shows that the presented FTL reduces response time in comparison to previous FTLs and can be used with relatively small size of caches.

  • This Study is concerned with the acceptance of Western timber structure and the interior space of church buildings in the early modern period in Korea. Timber roofs have represented a wide variety of constructional forms and have been fundamental to any technological appraisal of the evolution of both of Western and Eastern architecture. Especially the roof structure of the church buildings reflects the technological level, aesthetic sense, and spacial concepts of the age. Between Western timber structure and Korean timber structure, there are many differences in not only structural form but also form of roof, members, load, frame system and etc. And there were various types of framing technique such as timber truss, timber arch, timber vault in the western style church architecture in the early modern period in Korea. I have summarized the character of the acceptance process of Western timber structure and the influences on the interior space of church buildings.
