The purpose of this research is to improve exhibition effectiveness by implementing hands-on exhibition technique that best provides adults with cultural resting place and children with outdoor education which simply supports school curriculum. By completing this research, the museum of natural history will become defined innovatively as a place that enables people actively develop creativity. Seodaemun museum of natural history was selected for this research and itinerary tracking method of Robinson and Melton was adopted to find out adults' and children's particular movements in the museum. At the same time, observation method was used to get information on each room's visiting and viewing rate. In order to understand adults' and children's movements, their behavior was encoded.

Modern architecture does a role in terms of connecting traditional and current architecture. In the same time, Which is important part of korean architecture history because of introduction of western architecture. Accordingly, At this meaninglessly going out and leaving of modern architecture, the purpose of this study is systematic researching of 'Cho-sun government-general' interior which is disappeared. I progressed this study to research into the period context at construction of Cho-sun government-general md tendency of architecture and interior at that time. And then understand interior space organization of it. Cho-sun government-general adopted Neo-Baroque style from tendency of that time. Also, showed composite order which is mixed in the Greek temple, the Renaissance and the classic style representing the power. This characteristic is different from current composit order, which is comprehended by our. In order to understand aesthetic value of current straight interior space, It have to be interacted the present and past. But It's averted because it was made in the period of Japanese imperialism. Therefore, We should explore history of interior design that is endowed with sociality and historicity between modern and future interior space as well as current.

Safety qualification of a steam generator is a crucial issue related to faulted condition design loads, including earthquake loads, and it should be ensured that the structural integrity of a steam generator does not exceed its design load. Using data from the Gyeongju and Pohang earthquakes, the two most powerful recorded seismic events in Korea, seismic analyses of a typical steam generator are conducted in this study. The modal characteristics are used to develop an input deck for these analyses. With a time history analysis, the responses of the steam generator in the event of an earthquake are obtained. In particular, the displacement, velocity, and acceleration responses are obtained in the time domain, with these outcomes then used for a detailed structural analysis as part of the ensuing assessment. The response spectra are also generated to determine the response characteristics in the frequency domain, focusing on the response comparisons between the Gyeongju and Pohang earthquakes. Structural integrity can be ensured by performing additional analysis using results obtained from the time history analysis considering the input excitations of various earthquakes considered in the design.

This paper addresses the concept of lateral overstrength; the ratio of actual lateral strength to design base shear force, for both SDOF and MDOF systems considering soil structure interaction. Overstrength factors are obtained with inelastic time history analysis for SDOF systems for period range of 0.1-3.0 s, five different aspect ratios (h/r=1, 2, 3, 4, 5) and five levels of ductility (${\mu}$=2, 3, 4, 5, 6) considering soil structure interaction. Structural overstrength for MDOF systems are obtained with inelastic time history collapse analysis for sample 1, 3, 6, 9, 12 and 15 storey RC frame systems. In analyses, 64 ground motions recorded on different site conditions such as rock, stiff soil, soft soil and very soft soil are used. Also lateral overstrength ratios considering soil structure interaction are compared with those calculated for fixed-base cases.

In this study a procedure for evaluation of performance point using direct displacement-based design method was developed to enhance the applicability of the method. Parametric study has been performed for the natural period of the structure, yield strength, and the stiffness after the first yield. The proposed method was also applied to a 10-story steel frame. To verify the accuracy of the result, the results from capacity spectrum analysis and time history analysis were compared. The results of the proposed method turned out to match well with the results of capacity spectrum method and the time history analysis.

To realise the full benefits of a self-centering seismic resilient system, the designer must ensure that the entire structure does indeed re-center following an earthquake. The idealised flag-shaped hysteresis response that is often used to define the cyclic behaviour of self-centering concrete systems seldom exists and the residual drift of a building subjected to an earthquake is dependent on the realistic cyclic hysteresis response as well as the dynamic loading history. Current methods that are used to ensure that re-centering is achieved during the design of self-centering concrete systems are presented, and a series of cyclic analyses are used to demonstrate the flaws in these current procedures, even when idealised hysteresis models were used. Furthermore, results are presented for 350 time-history analyses that were performed to investigate the expected residual drift of an example self-centering concrete wall system during an earthquake. Based upon the results of these time-history analyses it was concluded that due to dynamic shake-down the residual drifts at the conclusion of the ground motion were significantly less than the maximum possible residual drifts that were observed from the cyclic hysteresis response, and were below acceptable residual drift performance limits established for seismic resilient structures. To estimate the effect of the dynamic shakedown, a residual drift ratio was defined that can be implemented during the design process to ensure that residual drift performance targets are achieved for self-centering concrete wall systems.

An inverse finite element approach is employed for more capability to design the optimum blank shape from the desired final shape with small amount of computation time and effort. For multi-stage deep-drawing processes, numerical analysis is extremely difficult to carry out due to its complexities and convergence problem as well as tremendous computation time. In this paper, multi-stage finite element inverse analysis is applied to multi-stage rectangular cup drawing processes to calculate intermediate blank shapes and strain distributions in each stages. Deformation history of the previous stage is considered in the computation. Finite element patches are used to describe arbitrary intermediate sliding constraint surfaces.

Currently the automobile parts manufacturing industry of most, it is difficult in the automobile part development and purchase and production management. And when new regulation it will develop this automobile parts and changing design, it is difficult in new registration and history management. Automatic history management and DB construction about automobile parts is in great demand. The purpose of paper is a design of data retrieval and real-time production integration management for automobile parts. Automatic data update is accomplished as input material changing process for design data change and integration management of history information about parts is possible when input the name of an part and the number of an part.

In this thesis, the Development of Station Buildigs Design during last a hundred years in Korea is analyzed. From the early time to today, several posts of Office of Korean National Railroads have controlled the Station Buildings Design by Standard Drawings. Sometimes, private architects joined in designing the Stations, that have the value as historic architecture. Under the Japanese imperialistic rule, Japanese Officer designed all of the stations ; that can be classified 1) wooden compromise style, 2) renaissance style, 3) northern European house style, 4) general station by standard drawing, 5) Korean house style. 6) modernism style. Especially, Korean house style was not planned to commemorate the old Korean Architecture, but to beguile the Japanese tourists' monotony of the journey in Korea. After the Independence, the Station Buildings are grouped into 1) international style, 2) modernism style with traditional details, 3) Station Complex Buildings. In the future, design of the Railroad Station Building needs to be diversified to satisfy tourists' emotion.
