The purpose of this paper is to investigate the removal efficiency of fine dusts as the configuration condition of machinery and equipments in Clean Room and to analyze the flowing behaviors of fine dusts as the layout of Clean Room. The layout of the Clean Room was classified into side layout type, 2 center line type and center concentration type layout, and the flow rates used in this research were 0.22m/s, 0.44m/s and 0.80m/s. Dust removal efficiency as layout change was decreased 37% for side layout type, 31% for 2 center line type and 20% for center concentration type layout at the flow rate of 0.22m/s, compared with the state without machinery and equipments in Clean Room. The efficiency was decreased 42% for side layout type, 22% for 2 center line type and 8% for center concentration type layout at the flow rate of 0.44m/s, and decreased 20% for side layout type, 18% for 2 center line type and 10% for center concentration type layout at the flow rate of 0.80m/s. According to the result of dust removal behavior, $0.3{\mu}m,\;1{\mu}m\;and\;3{\mu}m$ dust except for $5{\mu}m$ showed the higher change of the behavior in side layout type than in center concentration type layout due to the change of air flow. It was confirmed that removal behavior depends on the layout of machinery and equipments as the dust size decreases.

The objective of the present study is to predict the characteristics of the fire and smoke propagations in a clean room. Numerical calculations have been performed by using the finite volume method to obtain temperature and velocity distributions in the clean room. In odor to account for the turbulent flow characteristics, the standard $k-{\varepsilon}$ model is used. From this study, it was found that the fire propagation could be fully developed only after 150 seconds when the ventilation system in the clean room was off. And the smoke mass fraction showed a similar distribution as the gas temperature. Since the simulated fire was proceeded up to $20{\sim}30%$ of the room within 60 seconds. it could be recommended that the occupants should be evacuated from the room within 30 seconds.

The importance of improving semiconductor fab layout has been increased with the necessity of a large-scale capital investment and the increase of manufacturing complexity of the system. For the present, most semiconductor fab takes the form of a bay type layout where the same types of machines has been laid at the same bay. The bay type layout has many disadvantages in respect of material flow control even though it has merits of flexibility. To overcome the drawbacks of the bay type layout, a new room type semiconductor layout which integrates bays without a center spine and maintains the flexibilities of the bay type has been presented and compared with existing layouts. The results of test show that the room type layout is superior to the existing layouts from standpoints of transportation number and time, foot-print, number of stocker being passed and material flow time.

The purpose of this study is to clarify the spatial changes that have taken place in the main rooms (Anbang) and kitchens of traditional Utbangkkeokeum houses in Cheongju city, located on the central inland of Korea. These houses consist of a main house (Momchae) and a single-wing house (Nalgaechae), creating an ㄱ-shaped plan. The kitchen is in the front of the Nalgaechae, and the Anbang is at the rear. For the Momchae, the main hall (Daechung) is next to the Anbang, which is at the end of the Nalgaechae, and the room (Gunnunbang) is situated across from the Daechung. This study is based on the assumption that these houses have been conserved and altered from their original forms. As a result of alterations, many changes have occurred to the main room and kitchen spaces. The traditional main room is connected with two rooms (Utbang and Araebang), new standup kitchens are introduced, and floor heating systems are installed. The Anbang has maintained its sedentary lifestyle and the space for major daily activities such as sleeping and TV viewing. Also, TV viewing is a distinctive feature for residential purposes and the bedding is located in such a position that it is easy to observe any exterior movement for the elderly living alone. The layout of the standup kitchen has been altered to maintain the previous circulation, position and function of the entrance. Also, the kitchen and dining room were used together, and the size of these rooms has been partially increased from the original module in different ways for each case. The above findings suggest that Utbangkkeokeum houses of Cheongju city have been spatially changed while maintaining the previous lifestyle.

This study is about user satisfaction of the Junior College Library based on its characteristics of space composition. For this, we studied characteristics of space composition targeting the libraries in colleges in Seoul and Gyeonggi-do. First, in case of study of characteristics of space composition for books and library data, student satisfaction for traditional and normal library areas was high. It means that the service based on library areas should start from normal library areas as well as there is a change about space as the type of data in libraries change to electric data and multimedia. Second, If we look at the space for a reader and a user, satisfaction for a normal reading room was high. we can also see that satisfaction for a computer room and a multimedia reading room was not higher but still high. Also, the reason why satisfaction for a multimedia reading room that provides various activities was high was that the complex of a library space is needed to provide users with various activities. Third, in case of space for programme function and meeting, satisfaction for the room of video information and the group study room was high. we can see that user satisfaction for the space got high basically when a user is satisfied with the proper information technology based on interaction Fourth, as a result of variance analysis of 3 spaces of Junior College Library and the services, the size of the space of service does not influence user satisfaction directly. Even the space is small, if it decorates variously like with a lighting for a user, a window seat to meet the nature of users and has specific factors such as space reservation using internet, user satisfaction is high. If we summarise the result of this study, to make user satisfaction for speace in a Junior College Library higher, not just we need to try to make it extend as a educational, a cultural place but we also need to accept the student's requirement that the space also needs to be extend as a complex cultural space.

The objective of this research is to provide basic materials for future development of unit household plane of lease apartment house by comparing and analyzing the unit household plane of SH Corporation lease apartment house in Korea and PHA apartment house in the state of Minnesota, USA. For this purpose, the researcher chose 8 SH Corporation lease apartment houses in Yangcheon-gu Korea and 16 PHA apartment houses in St. Paul, Minnesota, USA. Drawing of 8 complexes of Korea SH Corporation, literary materials collected by Korea House Corporation and SH Corporation and the plane of USA were analyzed and the unit household plane of Korea and USA were processed by CAD to ensure exact analysis. Based on the drawing for CAD, the materialization work was implemented. The total size of materialized drawing and size of each room was drawn by using 'CAD POWER 2005' program. The result of this research is as follows. The plane of SH Corporation lease apartment house shows the difference in the plane composition from 12 pyung. Since LIVING ROOM is described in the drawing, the living room and bedroom seen in the existing size less than 12 pyung become independent as they are separate. While SH Corporation is composed in the form of kitchen that functions as dining room, living room functions as dining room in PHA. While SH Corporation shows 5 types, PHA shows different pattern in each complex. This is probably because PHA has diverse complexes. All planes of SH Corporation have entrance, which reflect the own character of Korea as it is. In PHA, the portion of receipt and storage space is very high.
