In the late Japanese colonial period, from the Sino-Japanese War until the Pacific War, critical discourses on the modern were prevalent in Japan and the Joseon. Despite the absence of a consensus about the specific definition of the modern, most thinkers agreed that the modern was something to be overcome. While some regarded naturalism and capitalism of the West as the essence of the modern, some others named scientism and humanism as the nature of the western modernity. Additionally, some criticized the temporal concept of historicism and brought new meanings of 'tradition' into relief, and some others advocated overcoming 'the West inherent in us'. This study is to consider the temporality of the theory of overcoming the modern focusing on the following three notions-world history, tradition, and emergency-, and examines the antinomy of them. The first notion to consider is 'world history'. The theorists of overcoming the modern, including the Kyoto school, discarded the progressive ideology that had led the Western modern history, and instead introduced 'world history' as a new notion. Although this resulted from the imperialistic embracement of the theories of Ranke, a major positivist historian from Germany, it contained antinomy of remaining in 'history' which was the modern temporal view. The second notion is 'tradition'. While the critical mind of 'world history' brought 'time of world' into question in the context of temporal realization, the notion of 'tradition' was to understand 'time of history' itself as the modern and overcome it. The critical mind of the notion involves the attempts to criticize regarding history as a 'progressive' process and to discover tradition as 'the present past' or 'the eternal present'. However, it also contained antinomy; the 'tradition' here was a notion that was created in the modern times, not passed down from ancient times. The third notion to consider is 'emergency', which was a method to define the present time as a transition period toward a new era, relating to states of war. However, the theorists of overcoming the modern did not regard 'emergency' as a particular time that strayed from normal states, instead they thought is as 'a regularized exceptional state', namely 'a state in which exceptions have become regulations'. However, the notion also contained antinomy since the word 'emergency' connotes abnormality.

Suncheon Songgwangsa has unique ventilation roofs. In the meantime, these roofs have been known as a characteristic element of Songgwangsa architecture and a unique element of Korean traditional architecture. I would like to review the installation time of the ventilation roof and check the installation time through Songgwangsa's records and photographs. According to the results of this study, it was confirmed that the ventilation roofs installed in various buildings including the temple of Songgwangsa were installed between the 1920s and 1930s. This can be summarized by comparing the history of Songgwangsa and the history of each building of Songgwangsa by comparing the paintings of Songgwangsa in 1886 and 1915 with the photographs of 1920s and Songgwangsa in the 1930s. It is a matter of further study whether the installation of the ventilation roof of Songgwangsa Temple is influenced by the Japanese occupation period.

The epoch-making event of history called "JE JU 4.3" took place in JE JU beautiful island on liberation political situation in 1948. The cruelties of this event were reported awful life loss over 30,000, cruel slaughter by government, scorched villages in mountain area, silence exaction and disadvantage of implication for long time over 40 years. But, the real features are in still a fog.. Recently, the searching movement has arised owing to democracy atmosphere and literature works with "JE JU4.3" materials were published from 1988 and the government announced official apologies in 2003. The novel "The Sun-set on Halla Mt", one of those works, is accessible to real history due to its time/space back ground and the real name of persons who were related with this event. It is important for readers to consider the difference between real history and fiction story. Because a historical novel should be evaluated by writer's theme rather than history character.

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.

This essay elucidates the way the geometries of space-time theories explain material bodies' motions. A conventional attempt to interpret the way that space-time geometry explains is to consider the geometrical structure of space-time as involving a causally efficient entity that directs material bodies to follow their trajectories corresponding to the laws of motion. Newtonian substantival space is interpreted as an entity that acts but is not acted on by the motions of material bodies. And Einstein's curved space-time is interpreted as an entity that causes the motions of bodies. This essay argues against this line of thought and provides an alternative understanding of the way space-time geometry explain the laws of motion. The workings of the way that Newton's flat and Einstein's curved space-time explains the law of motion is such that space-time geometry encodes the principle of inertia which specifies straight lines of moving bodies.

Even in moderate to low seismic regions like Korean peninsular where wind loading usually governs the structural design of a tall building, the probable structural impact of the design basis earthquake or the maximum credible earthquake on the selected structural system should be considered at least in finalizing the design. In this study, by using response spectrum analysis and linear time history analysis method, seismic performance evaluation was conducted for wind-designed concentrically braced steel highrise buildings. Both spectrum-compatible artificial accelerograms and recorded accelerograms were used as input ground motions for the time history analysis. The analysis results showed that wind-designed concentrically braced steel highrise buildings possess significantly increased elastic seismic capacity due to the system overstrength resulting from the wind-serviceability criterion and the width-to-thickness ratio limits on steel members. Time history analysis results generally tended to underestimate the seismic response as compared to those of response spectrum analysis.

The purpose of this study is to investigate nonlinear behavior and estimate ultimate resistance of the wall structure against seismic loading. Experimental data for RC coupling elements are used for specifying the strength deterioration and stiffness degradation factor of hysteretic model. Modified coupling element models are used in the push over analysis and time history analysis. In the time history analysis, three earthquake waves are used in the analysis and their peak ground accelerations are changed to be 0.2g. The conclusions of this study are as follows : (1) In the push over analysis, yielding of coupling elements occurred at lower story with small story drift ratio as 0.3%. (2) In the time history analysis, the story drift ratio is sufficient for the requirement of Korean Code, But coupling elements at most stories of the buildings occurred yielding. i. e. the earthquake resistant capacity of shear wall structures is not sufficient at 0.2g.

In this study, the seismic control performance of energy dissipation devices installed in a shear all-frame structure is investigated through nonlinear time history analysis of a 12-story building. Inelastic shear walls are modeled using the multiple vertical line element model (MVLEM) and inelastic columns and girders were modeled using fiber beam elements. For a seismic load increased by 38% compared to the design load, the seismic control performance was analyzed based on the results of a nonlinear time history analysis in terms of the inter-story drift, the story shear and the flexural strain. Friction type dampers was found to performs best if they are installed in the form of a brace adjacent to the shear wall with the friction force of 15 % of the maximum story shear force induced in the original building structure without dampers.

This study investigates the direct displacement based design (DDBD) approach for different types of reinforced concrete structural systems including single moment-resisting, dual wall-frame and dual steel-braced systems. In this methodology, the displacement profile is calculated and the equivalent single degree of freedom system is then modeled considering the damping characteristics of each member. Having calculated the effective period and secant stiffness of the structure, the base shear is obtained, based on which the design process can be carried out. For each system three frames are designed using DDBD approach. The frames are then analyzed using nonlinear time-history analysis with 7 earthquake accelerograms and the damage index is investigated through lateral drift profile of the models. Results of the analyses and comparison of the nonlinear time-history analysis results indicate efficiency of the DDBD approach for different reinforced concrete structural systems.
