Due to the paradigm shift of the industrial structure in the contemporary china society, the usage of practical function of industrial facilities goes down in this high developing society, so that it falls into some unused spaces. But the unused industrial facilities that including historical, symbolic and cultural meaning has been creating a new cultural space by giving architectural form and function through a variety of application methods for revitalization design. Especially, the facade design which fully expresses the function and meaning of building while properly expressing the cultural situation. It improves the living and cultural conditions of residents while giving the new symbolism of unused industrial facilities through various ways of application methods for revitalization. The unused industrial facilities that was reconstructed into the exhibition space in Beijing and Shanghai, china since 2006 is the object and scope of this study. The purpose of this study is to analyze the methods and characteristics of application methods for revitalization according to each component of the facade design in the idle industrial facility and to expect it to become basic data in the future design plan of unused industrial facilities.

Modern public museums are expanding its role as general cultural facilities. Therefore, the museums that are equipped with convenient and physical environmental features for all ages and types of users are needed. The purpose of this research is to evaluate the application of universal design in common space of the museums and to recommend a set of environmental improvement plans based on which various types of users can decide their choice of museums based on available data on the museums. The scope of this research was limited to seven major public museums located in Seoul, Korea. The spatial scope that was set for this research was common space of the public museums and the scope of the content was about the applicability of universal design. As a result of the research, three major conclusions were reached. First, the application of universal design toward common space in the public museums currently was not prevalent. Second, constant management and application development of universal design are needed. Third, as museums' primary roles and functions become more diverse, a direct application of delicate universal design is a necessary prerequisite to accommodate and fulfill users' needs.

The thermomechanical behaviors of SMA thin film actuator and their application are investigated. The numerical algorithm of the 2-D SMA thermomechanical constitutive equation is developed and implemented into the ABAQUS finite element program by using the user defined material (UMAT) subroutine. To verify the numerical algorithm of SMAs, the results are compared with experimental data. For the application of SMA thin film actuator, the methodology to maintain the precise configuration of inflatable membrane structure is demonstrated.

In this modern world of drastic change, folding architecture was an alternative that offered a novel architectural insight. Today, the folding technique is being used above and beyond architecture, spreading to fashion, lighting, medicine, etc. Especially in the interior space design field, the folding technique is in the limelight as an alternative to create an original space for modern society. However, research and experiments into folding mainly remains at philosophical interpretation or architectural examples, and even these were mostly before the 2000s. Therefore, the present study determined it necessary to look deeply into the post-2000s folding technique focusing on interior space. In this paper, 33 cases of indoor space where folding technique appears are derived, and classified them again by use. The folding technique which was the first step of Sophia Vyzoviti's experiment on her book, "Folding Architecture" was extracted and used as the framework. We summarizes the range of application of folding techniques (interior space in general, floor, wall, ceiling, etc.) and major folding techniques by combining photographs, drawings, and descriptions of the works of the architects. This paper summarizes the characteristics of the space described comprehensively, and draws out the spatial characteristics of the modern interior space where the folding technique appears.

Space development has been independently performed by space agencies in each country. This causes redundant development for individual function, resulting in waste of space resources. Accordingly, Interagency Operations Advisory Group (IOAG) was established for standardization with mutual agreement between international organizations, and space resources can be used efficiently between space agencies through cross-support. IOAG define Service Catalog#1, #2, and #3, according to the network layer. In this technical paper, the background and main contents of the IOAG Service Catalog, and the application plan for domestic space development will be discussed.

For the generalized nilpotent spaces, e.g. the locally nilpotent space, the residually locally nilpotent space and the space satisfying the condition ($T^{*}$) or ($T^{**}$), we find the pullback property of them. Furthermore we investigate some fiber properties of the space satisfying the condition ($T^{*}$) or ($T^{**}$), especially locally nilpotent space.

To prepare for a future Korean lunar orbiter mission, semi-optimal lunar capture orbits using finite thrust are designed and analyzed. Finite burn delta-V losses during lunar capture sequence are also analyzed by comparing those with values derived with impulsive thrusts in previous research. To design a hypothetical lunar capture sequence, two different intermediate capture orbits having orbital periods of about 12 hours and 3.5 hours are assumed, and final mission operation orbit around the Moon is assumed to be 100 km altitude with 90 degree of inclination. For the performance of the on-board thruster, three different performances (150 N with $I_{sp}$ of 200 seconds, 300 N with $I_{sp}$ of 250 seconds, 450 N with $I_{sp}$ of 300 seconds) are assumed, to provide a broad range of estimates of delta-V losses. As expected, it is found that the finite burn-arc sweeps almost symmetric orbital portions with respect to the perilune vector to minimize the delta-Vs required to achieve the final orbit. In addition, a difference of up to about 2% delta-V can occur during the lunar capture sequences with the use of assumed engine configurations, compared to scenarios with impulsive thrust. However, these delta-V losses will differ for every assumed lunar explorer's on-board thrust capability. Therefore, at the early stage of mission planning, careful consideration must be made while estimating mission budgets, particularly if the preliminary mission studies were assumed using impulsive thrust. The results provided in this paper are expected to lead to further progress in the design field of Korea's lunar orbiter mission, particularly the lunar capture sequences using finite thrust.

This study has the main objective of being of help as a reference data for the application of the finishing materials when designing the interior of the chapel of the church space through analysis of the finishing materials against the chapels of church space which has complex function. As precedent studies for this, the composition of the function and concept of the church space was surveyed and the complex function of the church space was surveyed. The theoretical surveyed was performed according to the casual composition, behavior of the community and role and location of the duties of the church members. The case objects were 10 chapels constructed by 5 professional interior design companies. The content of the analysis was the finishing materials in the chapels and their application characteristics. The detailed considerations to be referred to when designing the interior of the chapels of church space in the future were proposed. The analysis result of the application of the finishing materials according to the locational function of the chapels of church space can be explained as follows. First, the platform area was the characteristic of applying finishing materials which induce visual immersion. As for the floor materials in the platform, in order to minimize the floor sound and vibration phenomenon occurring during movements, noise insulation and dust protection rubber sheet was place and on top of it the floor or the carpet was placed. Second, the Choir area had the difficult problem of having to consider the appropriate sound absorption occurring due to the proliferation of sound and performance of classical instruments at the same time. However, in the case, this problem was solved through the sculptures of convex shape. Third, since the scheelite is a space where many people move around, the finishing material which absorbs sound was mainly used. Fourth, the entrance area was composed of thick wall materials compared to other walls, and the sound absorption character was most significantly considered when applying the finishing material. Fifth, the broadcasting room was composed either in independent type or an open type and performed its function and the main finishing materials was transparent glass which was highest use frequency.
