In modern city, art museum is regarded as significant institutions because it includes educational roles beyond the means of facilities for historical exhibitions. Based on these flow, various research of museum's space with view from the operational point to the spatial analysis point has been approached. Moreover, it is required to address human behavior in art museum space on the ground that lots of audience move simultaneously. In the field of interior architecture, it is also necessary to analyze how design elements affect the human behavior directly and use the method of controling a circulation. In this research, based on the role and importance of the basic components of the interior space, re-interprets the exhibition space based on the relevant theory, to comprehensively examine the influence the shape of the space is on the substantially walking behavior. Therefore, first is to determine whether the spatial type corresponding to the position of the connectors in the exhibition space. Second is to conduct the investigation observation for gathering the actual viewing exhibition circulation. Finally, it analyzed whether the observed actual circulation and planned circulation matched. As the result, the position of the connectors is that causes the difference of the spatial configuration, which affects the viewing circulation was found. The significance of the research is to present the form to plans of the interior space as a method of reducing congestion perception of viewing circulation.

Infrared stealth is an important technology for naval ships. This technology helps improve the anti-detection performance and survivability of naval ships. In general, the infrared signature of naval ships are categorized into internal and external heat source. External signature are generated by ship surface heating by solar flux as well as the complicated heat transfer process with the surrounding weather condition. Modern naval ships are equipped with seawater injection nozzles on the outside for nuclear, biological and, chemical, and these nozzles are used to control external signature. Wide nozzle placement intervals and insufficient injection pressure, however, have reduced seawater dispersion area. To address this problem, nozzle installation standards must be established. In this study, an actual-scale experimental system was implemented to provide the evidence for nozzle installation standards in order to reduce the infrared signature of naval ships. In addition, the environmental conditions of the experiment were set up through computational fluid dynamics considering the ocean climate data and naval ship management conditions of South Korea. The dispersion distance was measured using a high-resolution thermography system. The flow rate, pipe pressure, and dispersion distance were analyzed, and the evidence for the installation of seawater injection nozzles and operation performance standards was suggested.

The history of the Korean lighthouse have been known to be begun from which installed by the purpose of the Japanese invasion of the outside. Modern navigational aid system have configured during the Japanese ruling era since the Incheon Palmido Lighthouse was built in 1903 as the first lighthouse in Korea. But in this regard it needs to be considered more carefully. Busan, as the city of international port and of Choryang Waegwan, had been a center of foreign relations between Korea and Japan since early 15th century. Because that reason, International port facility has been developed for a long time ago in Busan for example lighthouse, breakwater, wharf, jetty and so on. Nevertheless the lack of historical data and basic research related to the marine caused the proper history could not be established until now. In recently the basic translation of Korean Maritime Customs documents started to finish, and a compilation book of old pictorial maps on Choryang Waegwan was issued. As a result, more objective history of Busan Aids to Navigation can be investigated.

The purposes of this study were to compare Louis I. Kahn and Rem Koolhaas, both of whom established their architectural theories and granted rationality to them by applying the theory of psychoanalysis, and examine common and different characteristics in the inner space composition of a building between them. The study also set out to confirm a basic premise based on which to develop a metaphysical design concept by applying the theory of psychoanalysis in the inner space composition of contemporary architecture in future from the more developed and integrated perspective of modern psychoanalysis. As a result, Kahn sought after a metaphysical design concept through the combinations of inner unit spaces including servant and served space, which are comparable to the confrontation between consciousness and unconsciousness from the perspective of psychoanalysis. Unlike him, Koolhaas applied the concept of folding to his architectural plans based on the theory of post-structuralism and created a metaphysical design concept by more focusing on connections between unit spaces rather than their combinations. While Kahn worked on his designs with much interest in the combinations of inner unit spaces in horizontal circulation by separating it from vertical circulation, Koolhaas created a new design concept beyond the limitations of Kahn, who had a confronting, dichotomous view of the world between the phenomenal world and the metaphysical world, by making use of inclined slabs to connect upper slabs with lower ones. The findings show that there can be various metaphysical design concepts depending on how to connect and combine two confronting concepts when applying the theory of psychoanalysis to architectural design.

Modern embedded system employs a hybrid architecture which contains a general micro processor and reconfigurable devices such as FPGAS to retain flexibility and to meet timing constraints. It is a hard and important problem for embedded system designers to explore and find a right system configuration, which is known as design space exploration (DSE). With DES, it is possible to predict a final system configuration during the design phase before physical implementation. In this paper, we implement a timing analysis simulator for a DSE on a hybrid embedded system. The simulator, integrating exiting timing analysis tools for hardware and software, is designed by extending Y-chart approach, which allows quantitative performance analysis by varying design parameters. This timing analysis simulator is expected to reduce design time and costs and be used as a core module of a DSE for a hybrid embedded system.

The architectural design process is consisted of the phase of programming and the phase of the design. The contemporary architectural scheme, as a datascape, a rhizome structure and a diagram, is based on the concept of modern physics. And it is applied on the phase of design by synthesizing data. Like this, the design of the architectural field is accomplished in the phase of design. For design of the architectural field, the characteristics of the architectural field is considered as the viewpoint of design in the procedure. First, according to the area which is defined by relations of environments, around architectures and so on, the net system of relations is designed as area. Second, design the linkage between building and space, building and building, space and space, according to the correspondence each other. Third, design the method or form of connecting building and space to one as a building and a space are no longer divided but are understood by one. As a result, for the design of architectural field, it is necessary to define the criteria by the characteristics of architectural field and the architectural field is designed by process.

Building energy demands have highly risen in modern society; thus, It is necessary to reduce building energy demands especially commercial buildings adopting a curtain wall architecture. Curtain wall architectures have a high ratio of windows which is a vulnerable in heat insulations as cladding. In order to complement insulation performance of windows in these buildings, there are various methods adopted often such as installing blinds, wing wall and films. There are two suggestions of this paper. 1) WWR (Window-to-Wall Ratio) makes a impaction of energy demands in buildings. 2) Another one is an efficiency of blind systems which are installed in buildings in order to reduce cooling demands. It is also critical to make fundamental model for low-energy building construction by processing a lot of simulation As a result by this study, 1) an external blind system is more useful for reducing cooling energy demands rather than an internal blind system. 2) Buildings which have a large window require more amount of cooling demands. In case of WWR 45%, it needs more cooling energy rather than WWR 15% model's 3) Adopting blind system would reduce energy demands. WWR 45% model with external blind systems reduces about 4% of cooling energy demands compared to same model without any blind systems.4) it is necessary to study an efficiency of blind systems combined with renewable energy and it will be possible to reduce more energy demand in building significantly.

The research efforts to modernize Hanok (Korean traditional housing) have been performed to improve the quality and cost-effectiveness through application of modern building methods and materials, and to disseminate it in various forms of sizes and facilities. In this study, in order to identify the variations of modernized Hanok, data from seven test-bed projects are analyzed based on the building work-section, element, method, and material. The data were standardized and managed through the modernized Hanok classification system (Hanclass) to facilitate systematic comparisons of the test-bed projects by the variation of building method and it's cost impact. Identified factors of the variation in terms of building methods were then itemized and quantified in terms of building cost. Findings of this study indicate that the timber structure is the most critical area for future variation for improving the quality and cost-effectiveness. The results of this study will be also used to systemize the Hanok database for further studies.

The purpose of this study is to explore the characteristics of spatial expression in the works of Terunobu Fujimori, Japan's leading eco-friendly architect, in line with the contemporary background on environmental issues. As a method of research, we will select five representative multi-room spaces from the 1990s to the present and explore the characteristics of expression in the space through literature research. As a result of the analysis, we were actively using the strategy of using natural materials to finish the space and introduce plants into the building. Japan's strategy of borrowing traditional methods was to use them as a way of expressing space, a way of expressing fantasy and deviance. We expect that the demands of modern people seeking novelty in this era and the eco-friendly building plan of feasible alternatives can be presented as another methodology for spatial design.

"Death is the side of life which is turned away from us." The life of people in Seoul, however, is disconnected from death. Why? This article compares the historical changes in the cemetery disposition of Paris and Seoul to answer this question. The cemetery is always a meeting place between the living and the dead. In pre-modern cities, the cemetery was close to the people's daily life. However, the fundamental change of urban structure due to modernization has a great influence on the cemetery. With the advent of the train, the world has shrunk and the city has expanded unprecedentedly. In such a situation, the cemetery is expelled to the outside of the city. However, while Paris and Seoul share the same overall flow, they responded differently to the plans for the establishment of large-scale remote cemeteries. In Paris, the plan was canceled by citizens who value their relationship with the dead. On the other hand, Seoul was unable to manage the cemetery due to social confusion in 20th century. All cemeteries were expelled as industrialization began. As a result, there is no public cemetery or ossuary at present in Seoul. In Seoul, about 20 years ago however, a new kind of place for the dead began to appear. It is an ossuary attached to religious facilities. In other words, the current cemetery of Seoul is divided into two forms : the public cemetery, which is expelled from the city, and the private ossuary, which is attached to religious facilities built in the city.
