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.

The purpose of this study are to investigate the actual conditions of residing environment in children's room and it's utilization. Further, basic for the guidence and the effective preparation of children's room and children's residing environment in addition willbe produce through grasping the actual conditions of them.The subjects of this study were 214 5th grade elementary school children living in Taegu. The analysis of the data was done through SPSS pc programs.The major findings of this study can be summarized as follow;1. The greater part of children had their own room, and they had the desk, the book case and the clothes chest in their room. But the numbers of children with the bed were few in comparison to those. And a large number of children wanted to have the bed and the computer in their room.2. There were significant differences in the actual conditions of residing environcent in children’s room according to the independent variables. For example, the existence of children's room was variable according to farther's job(0.1% level).3. The case of having their own room in the period of the lower grades in elemtary school dccupied the highest percentage. A lage number of children passed away time mostly in the women'a guarters. In the cleaner of children's room, the case of doing themselves occupied the highest rate as 51 percent.4. There were significant differences in the actual conditions of utilization in children's room according to the independent variables.

Recently, since there appear the quality improvement in both educational and cultural level at the college campus also, thus the lecture room is requiring by the students where the intimacy degree among the students can be raised, also a smoother interaction between the professor and the student is able to be generated. Particularly in case of College of Music, the Practical Technique Training Rooms such as Orchestral Music Room, Pipe Music Concert Room, Music-Part Practice Room are more important for the interaction between Professor and Student or Student attends at the lesson, than the lecture rooms of any other colleges. Likewise, while such music practice room should be designed with consideration of the acoustic characteristics, so as to obtain the feel as if hear it performs at a music hall, but since the most of music practice room was designed with consideration of the convenience of construction work and its economical efficiency only, it has been exposed with many acoustic defects after the completion of construction. Therefore in this thesis, it has grasped the physical acoustic characteristics on the object of the two orchestral music rooms, pipe music concert room and ensemble practice room, among the newly constructed practice rooms of the Music College, W University, and it is considered that it could be utilized as the fundamental data on the base of this material when designing of the college music practice room, for the future.

Purpose: The aim of this study was to analyze various nursing services of delivery room nurses by hospital level, and identify importance and frequency to provide baseline data to establish delivery room nurses' roles. Methods: Through DACUM analysis technique, service descriptions, duties, and tasks were derived from the literature. A survey was done of 242 nurses from delivery rooms of hospitals, general hospitals, superior general hospitals, and special hospitals. Importance and frequency of each service were measured using a 4point scale, and results were analyzed using SPSS. Results: Nursing services for delivery room nurses consisted of 18 duties and 86 tasks. Duties with the highest importance were 'labor support' and 'infection management', and those with lowest importance were 'collaborative care' and 'communication'. The duty with the highest frequency was 'labor support', and lowest frequency was 'communication'. There were differences between importance and frequency depending on the size of hospitals. Conclusion: Results of this first study on nursing services of delivery room nurses. delivery room nurses are performing a wide range of nursing services and the various types are clarified including importance and frequency.

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.
