In terms of cultural history, museum architecture represents culture of society in an era. exhibition space which represents the society and culture can't be fixed in the same way in a current mobile era. Especially, mobility of exhibition can be able to give audience even opportunities to enjoy. As a result, mobile exhibition space that functions as total space for everybody and the study of this issue is necessary. As mobile exhibition space is in the middle of development, there are many things to make up for the weak points. In order to make mobile exhibition space more competitive, development of new form and material is needed most. besides, limited development on interior plans which has been overlooked in terms of mobility is needed. Also, there should be more aggressive and powerful marketing and promotion for mobile exhibition space. To equalize the metropolitan area and local exhibition space and revitalize domestic exhibition space, the utility of mobile exhibition space which is movable and economic is highly expected more than previous fixed exhibition space.

The binding interaction between a hemolytic peptide ${\delta}$-lysin and a zwitterionic lipid bilayer POPC was investigated through a series of molecular dynamics (MD) simulations. ${\delta}$-Lysin is a 26-residue, amphipathic, ${\alpha}$-helical peptide toxin secreted by Staphylococcus aureus. Unlike typical antimicrobial peptides, ${\delta}$-lysin has no net charge and it is often found in aggregated forms in solution even at low concentration. Our study showed that only the monomer, not dimer, inserts into the bilayer interior. The monomer is preferentially attracted toward the membrane with its hydrophilic side facing the bilayer surface. However, peptide insertion requires the opposite orientation where the hydrophobic side of peptide points toward the membrane interior. Such orientation allows the charged residues, Lys and Asp, to have stable salt bridges with the lipid head-group while the hydrophobic residues are buried deeper in the hydrophobic lipid interior. Our simulations suggest that breaking these salt bridges is the key step for the monomer to be fully inserted into the center of lipid bilayer and, possibly, to translocate across the membrane.

When observing an object in a space, a part of it is remembered into our perception in the time for paying attention or conscious observation and it reaches to our visual understanding. In this study, it examined characteristics by each subject through the process of visual understanding by changes in such observation time. The results from this study are summarized as belows: First, through analysis of the observation data focused on the distance between the observed points, it was able to apply those visual theories organized before to the analysis of characteristics of the time for understanding by each subject. Second, there showed big differences in the time for visual understanding by each subject according to changes in the observation time so that it was found that there were big differences according to the characteristics of subject's intention or purpose of the observation of a space. Third, as the number of continuous observation gives an important clue in judgement of how well the space was understood, it was able to compare and organize the mutual characteristics of the time the attention was concentrated, the time observed intentionally and the time understood visually. Fourth, it was found that the shorter subjects gave the intentional observation in observing a space, the longer they spent the time for paying attention, while the less they could understand it visually.

The relationship between users and physical elements of environmental gives a space special characteristics. The Environment Probabilitism by Altman shows that behavior and environment, both response, effect each other construct their characteristics. People can choose their response consciously or unconsciously during their walking , sitting, standing, talking in their environment. Designing a good place can lead people to the goal that they want and designer intend to get, A good place well designed as an positive place is organised with 3 points(1) User's behavior (2) physical elements in environment (3) meanings produced between behavior and physical elements. In this study the importance of physical elements are focused on. In the place where we can have permeability, variety , legibility, robutness, visual appropriateness, richness, personalisation physically , these characteristics will encourage people to have strong motivation and to choose the most active way . From this perspective the circulation of physically handicapped persons is analyzed into their behavioral environment and their behavioral response. The analysis shows the handicapped in our situation has no environmental right for a man itself ,even they have no street to walk safely. And their response to the environment was very negative. Basically the elements from exterior space to interior space should be guaranteed for everyday according to their behavioral characteristics include handicapped. From this study the result shows that the needs of a person should be considered and accepted as an important design problem for improvement our environment.

Design has been proceeding to 21 century undertaking the many-sided and complicated characteristics of the modern industrialized society much more heavily comparing to past. The rapid change of technology and media of communication faces the new concept of relationship between users and environment, and newly developed material leads designers to change the way of building concept and the process of designing. Especially the important points of user-friendly and environment-friendly approaching for designing influences over choosing, controlling meterials and forming the structure and shape organically, or simply. From the tendency of chairs designed in 1990s the very adaptable new material shows both the unlimited possibility for new design is in the turn of this century, but also it can be analogized that 'the design which can make users think' will be the philosophical basis for future desigv.

The first object of this study is to clarify the newly demanded service to the visiter in the museum. And the second is to consider the spatial configuration on the layout of exhibition and the shape of exhibition room from the view points of behavior of appreciation and other methodology. The results of this study are as follows : The exhibition content and structure of Seoul Museum of History formed by a story-line according to the theme of an each zone fixed sequence in an each exhibition that we are achieved. But the layout of exhibition and the shape of exhibition consist on the other hand of the freedom selection. So the problem appeared In the difference of the exhibition content and the layout of exhibition to the behavior of appreciation. It can be said that the concept of exhibition space should be taken into account and the spatial configuration by the completed floor plan in order to satisfy the planning concepts.

In general, surface mounted PM synchronous motors (SPMSMs) are mainly adopted as a driving motor for high-speed applications, because they have high efficiency and high power density. However, the SPMSMs have some weak points such as the increase of magnetic reluctance and additional losses as a consequence of using a non-magnetic sleeve. Especially, the magneto-motive force (MMF) in the air-gap of the SPMSMs is weakened due to the magnetically increased resistance. For that reason, a large amount of PM is consumed to meet the required MMF. Nevertheless, it cannot help using the sleeve in order to maintain the mechanical integrity of a rotor assembly in high-speed rotation. Thus, in this paper, a multi-layer interior PM synchronous motor (IPMSM) not using the sleeve is presented and designed as an alternative of a SPMSM. Both motors are evaluated by test results based on a variety of characteristics required for an air blower system of a fuel cell electric vehicle.

It is generally known in seismic design that the beam yield type frames have more advantages than column yield type of which damage is likely to concentrate to any story. However we may design a building as a beam yield type, it becomes actually a column yield type collapse mode for slab floor diaphragm effect. Considering these points, the column yield type frames are selected and designed as the specimens. The object of this study is to grasp quantitatively the restoring force characteristic values and to estimate the seismic performances of column yield type steel rahmen.
