The development of human civilization has been accompanied by a corresponding development of storage facilities. In particular, the storage of residential spaces not only performs the storage management function for personal property but also is considered an important prerequisite for a comfortable life. While examining the history of the transformation of built-in furniture, this study emphasizes the social and cultural implications of Korean residences. Therefore, We attempt to uncover the Korean characteristics that can be discovered in the transformation of storage furniture according to the changes that occurred in Korean residential forms following the modern era and to question the problematic issues of the built-in furniture in Korea.

It is not easy to clarify the historical perspective of architect through his architecture. Exceptional cases, it will be the time to design a history museum. As an institution, a Museum already became an apparatus to represent the history to it itself. Libeskind's Jewish museum Berlin has been presented as the controversial case most of all. In particular, in that it instead of dealing with history positive, that contains a tragic history, this building is a building that history a unique interpretation of the architect has been a problem. Therefore, it is difficult to find a suitable example to Libeskind's Jewish museum in Berlin to try and look at the problem of the history of contemporary history and interpretation of the architect. In this paper, I am trying to interpret Libeskind's Jewish Museum Berlin through the aesthetics and history philosophy of Theodor Adorno and Walter Benjamin. They are Jewish and the central figures of the Frankfurt School, known as 'critical theorists'. Their critical theory was formed based on the experience of the Jewish genocide and war.

Meoricho of Dancheong is a pattern that placed at the end of each elements. We call Dancheong which has Meoricho Moro-dancheong. Meorico is the pattern comes from the metal ornaments of ancient architecture. The most primitive forms of Meoricho is Saw-toothed Design. Since the influence of Buddhism in the Northern Wei dynasties Saw-toothed Design have changed Tied lotus Design. Tied lotus Design of the Unified Silla it becames Gak-yeop Design and Yeo-ui-doo Design Meoricho in Goryeo Dynasty. Since Goryeo Dynasty there's been great and small variations in the internal composition of Meoricho, but the outline has maintained as it was. Therefore the completed form of the outline of Meoricho could be regarded as the one that was formed in Goryeo Dynasty.

In the current seismic design codes design earthquake is usually defined as the earthquake with the 90 percent probability of not being exceeded in the life time of a structure which is assumed as 50 years equivalent to the earthquake with 475 year recurrence period. However the life time of tall building structures may be much longer than 50 yers. The current seismic design code requires the modal analysis or dynamic time history analysis for the buildings with the height exceeding a certain height limit. The objective of this study is to collect the earthquake ground motion(EQGM) which can be used for dynamic time history analysis for tall buildings. For this purpose linear elastic design response spectrum (LEDRS) in the code is scaled to account for the recurrence period of the design earthquake. The earthquake ground motions which has been recorded are calibrated to fit the scaled LEDRS. The set of calibrated EQGM can be treated as design EQGM for the design of tall building with longer lifetime than ordinary building.

High Tech Design manner is a design concept that had been constantly discussed in constitution process of the West art history and modem ideology and had been experimented in industry, having started from futurism and structuralism in the early 20th century through Kinetic Art & Technology Art and up to now. High Tech Design had a great influence also on Post Modernism and more important is that this manner of design will be existing continually in the future too. From the modem times when machine civilization started, the artist and designers expressed a utopia will showing the future world with help of High Tech Design and modem people are realizing technology images as a utopia, in the space and material presented by this high tech design. And this utopia imply the images of dynamic power, speed making a voyage in universe, dream of future, hope, mass production, earth's environment, wealth etc. High Tech furniture was lightly designed by using thin steel wire, structure stressing the metallic characteristic and tempered glass, and it was used for presenting a convenient interior space visually, and with that it can make a unified sense in High Tech interior space, and a contrary effect compared with minimal space. High Tech Design equipped with glass and metal materials looking inappropriate for our interior space due to their sharp and cold image has been regularly used as living furniture, not only decoration function, and then there must be reasons for that. This study intends to research how High Tech Design has been changed and developed in the design history & West art history from the early 20th century, and to present it's value of development as data orienting, namely a direction for the industry of the next-generation and furniture design.

In the event of an earthquake, non-structural components require seismic performance to ensure evacuation routes and to protect lives from falling non-structural components. Accordingly, the seismic design code proposes horizontal force for the design and evaluation of non-structural components. Ground motion observed on each floor is affected by a building's eigen vibration mode. Therefore, the earthquake damage of non-structural components is determined by the characteristics of the non-structural component system and the vibration characteristics of the building. Floor response spectra in the seismic design code are estimated through time history analysis using seismic waves. However, it is difficult to use floor response spectra as a design criterion because of user-specific uncertainties of time history analysis. In addition, considering the response characteristics of high-rise buildings to long-period ground motions, the safety factor of the proposed horizontal force may be low. Therefore, this study carried out the horizontal force review proposed in the seismic design code through dynamic analysis and evaluated the floor response of seismic waves considering buildings and predominant periods of seismic waves.

Computerized visual database construction of architectural precedents has just begun in some research institutes in the world. In Korea the first visual database has shown its testl version by S architectural design firm in september 1996. In this article the author discusses the historical contexts and the recent computerization cases, the traits, the uses and the limits of architectural visual database system of precedents. The forms and contents of data fields in two cases are compared with a focus on the description of architectural traits of each data entry. Compared to the KIA format, the S database has better performance for architectural design reference because it collects more pictures and drawings and larger texts for the field of architectural chracteristics. But this latter also is constrained by its capacity of memory and so lacks the reciprocity of the DOORS in the Graduate School of Design, Harvard University. A visual database system which has more flexible allocation of memory and respondent with the users is yet to be prepared. But this system also should be maintained by some experts in architectural history, theory and criticism, because their knowledge is essential for selection of precedents and revision of the data description. A full-fledged electronic visual database in architecture will not only save much effort for the architect, but also will change the architects' design behavior. Nevertheless this does not mean the automatic promotion of architects' creativity.

Existing elastic analysis methods cannot be adhered to in order to assess the structural integrity of a reactor vessel and internals for a beyond design basis earthquake. Elasto-plastic analysis methods are required, and the factors that affect the elasto-plastic behavior of reactor materials should be taken into account. In this study, a material behavior model was developed that considers the irradiation embrittlement effect, which affects the elasto-plastic behavior of the reactor material. This was used to perform the elasto-plastic time history analyses of the reactor vessel and its internals for beyond design basis earthquake. For this investigation, appropriate beyond design basis earthquakes and reliable finite element models were used. Based on the analysis results, consideration was given to the load reduction effect and the margin change. These were transferred to the internals due to the plastic deformation of the reactor vessel.
