  • This study is to examine the sound transmission loss of a railway vehicle floor. To this end, a semi-reverberation room was constructed. The semi-reverberation room was made of a railway vehicle floor between the sound radiating chamber and the sound receiving chamber. To block the sound, the wall was made of acryl, urethane foam, wood, and glass fiber. The test followed the KS F 2808 standard, and a typical reverberation room was used to verify the performance of the semi-reverberation room. As a result, comparison of the measurements showed that the test results of the semi-reverberation room had the same tendency as those of the reverberation room. Consequently it was possible to measure the sound transmission loss of railway vehicle structures using the semi-reverberation room.

  • A relationship between the museum display wall composition and the visual spatial configuration is investigated in this study. From the previous research, existing types are classified in order to define the exhibition space of room to room. Based on the classification, an open room to room of art museum is defined as a room to room of museum, and the plane of museums is investigated. With the museums under this study, the wall of a room to room exhibition space as well as the visual spatial configuration are analyzed depending on the location of an opening, centering on the composition of unit space. In addition, two types of spatial composition are compared depending on the location of the opening. One type of spatial composition is lied on a straight line with visual continuity, and the visual line is found to be simple. Whereas, the other type has an invisible configuration between spaces due to a criss-crossed opening, so the space is perceived to be closed and disconnected. When comparing these two types, the advantage and disadvantage of each space are compared. As a result, a similar type and size of unit space are derived. In addition, the ratio of the opening compared to the total wall was found to be uniform, and a distribution of the opening and walls were found.

  • This research is done to design and manufacture prototype clean room garments to improve the product yield of the clean room processing. To assist the research, other papers and references on the same subject were collected for analysis. Also the researcher made interviews with the workers at the clean room. The prototype garments made for this project was compared against the commercially available clean room garments used in the industry. A set of test was conducted to measure particle release from the garments. The prototype clean room garments was manufactured after having considered all the aspects stated above, and tested for the level of particle release. The test subjects performed 4 different movements(marching, arms stretch, squat and rise, and jogging) while wearing the prototype garments and commercially available clean room garments. Particle counts produced by each movement were measured. The data collected was statistically analyzed. The followings are the result of the test. 1) Overall, the prototype garments yielded less particle release.(p<0.001) 2) It showed greatest difference of particle counts for jogging(p<0.001) and squat and rise(p<0.001). In the arms stretch test. the prototype garments was also more effective in controling the particle, however, in the marching test. no significant difference was detected. 3) The prototype garments had less particle release in upper(p<0.001), middle(p< 0.001), and lower level(p<0.01) than the commercially available clean room garments. Manufacturing a new fabric for the clean room processing is important, but this research proves that the design of the clean room garments also determines the efficiency garments in the particle control. Therefore the same fabric can perform differently according to how it is designed. Improving the design will also improve the 7article control and reduce the cost of research. Eventually, the manufacturers will increase the product yield.

  • The purpose of this study is to suggest the materials for developing the new house style by analysing the space characteristics of wood frame houses in suburbs of Seoul. For this, we analysed 45 drawings(site plan, floor plan, elevation, section) that were designed by MICHOO, WOOD-LAND, STUGA and CHOWONJUTECK company etc. The space design characteristics that we found are as follows; 1. The wood is fragile to humidity. Therefore this characteristic is especially considered in designing the space of bathroom and utility room. 2. It is the merit of wood frame house that inner space can be designed variously by using spilt-level and the slope of roof. 3.The public space and private space are completely separated in most cases and the stair is located in the middle of house. This structure of house is short of horizontal openness. Instead, most houses gets vertical openness by making second floor on the living room opev. 4. In wood frame house as the rural house, the outer space is well used by setting up deck and balcony. The outer spaces like deck and balcony are usually used as a part of life space in connected with living room, dining room, master bed room and family room. 5. The public spaces like kitchen, living room, dining room and family room are considered so important in design that those are arranged in front in order to have good outlook and directiov.

  • We have analysed the use and organization of space in the Centres des Documentations et de Informations(CDI) in lycees in France with the equivalent information centres. The majority of CDI are located in close proximity to the Academic staff and provide easy student access. The CDI provide not only books but also reviews, magazines and CD-Rom. This information is very important to pupils both in the pursuit of their higher studies and also with their future professional life as there is also careers information available to be discussed regularly with the careers advisor. The function of the CDI is not only to provide information. As part of the curriculum there are classes on how to access the information available in the CDI as well as Seminars and Audio-Visual courses. This management makes it possible for the CDI to operate, not only as a school library but also as a multi-function centre of documentation and information; a variety of spaces are also available: a room for private/small group study. A computer room (as well as a research corner), a reading room, monthly review room, photocopy room, rest room, exhibition room, careers information room, audio visual room etc. The results of this study can be used as essential information during the space planning of Korean school libraries in the future.
