For housing estate of a new administrative capital city, Noise reduction method is a important design factor. As measuring a noise level of traffic noise according to separation from road, it can be created a quite housing estate. Analyzing of merits and demerits in sound barrier walls and tunnels can be proposed environment friendly soundproofing facilities. Number of measurement was performed to know what kind of layout of housing estate is good for noise reduction. Through this measurement, ㄷ shaped layout or parallel layout has the advantage of sound insulation rather than right angled layout. In this case (ㄷ shaped layout or parallel layout) buildings neighboring to the road should be designed to insulate sound. Evergreen trees should be planted between housing estate and road more than 30m (at least 7～8m) in order to reduce noise and have masking effects. If broad-leaved trees are planted more than 30m, approximately 10dB noise is reduced and 2～4dB if 7～8m. Roads in the estate should be designed considering pedestrians first, and special roads for moving and ambulance should be designed as skew road, if possible. The result shows that 15$^{\circ}$-sloped‘S’road reduces 1～2dB noise and 30$^{\circ}$-sloped road reduces 4～7dB. If noise barrier is inevitably installed, it should be designed to go well wit neighboring environment so as to install Environment Friendly Noise Barrier using materials and trees including wood and soil. Through this study the results are used to guideline for construction of environment friendly housing estate

I The Purpose of this study is to look in to the production of high-functional clothing industry, such as item, style, layout, labor, suggest some effective solutions and alternatives for them. 23124554 For this purpose, the companies specialized in manufacturing of special high-functional clothings were sampled for a survey using interview and a questionnaire. The results of this study can be summarized as follows; It was found that since demands for high-functional apparels are low and their sewing processes are much complicated requiring expensive equipments, only a few companies are engaged in such apparels. In addition, since the quantity of order s small and material inputs are more frequently changed, the sewing processes on the production line need to be changed together with the production layouts. On the other hand, as the materials used are very special, expensive equipments should be used, for which the companies feel much burdensome financially. Accordingly, t is deemed necessary for the high-functional apparel manufactures to specialize the processes requiring specialized equipments or outsource some of them or recruit highly-skilled workers.

This paper is on the research of the special character of the dynamic response according to a design of the clamped reinforced concrete slab. In this study, the 20-node solid element has been used to analyze the dynamic characteristics of RC slabs with clamped edges. The elasto-visco plastic model for material non-linearity and the smeared crack model have been adopted in the finite element formulation. The design factor, which affect the dynamic response of the reinforced concrete slab, are the steel layer thickness, steel layer depth, steel layout method, steel layout angle and the slab thickness and span ratio. The main purpose of this study was to find out the dynamic response of the reinforced concrete slab according to above variables. The reduction of deflection/thickness ratio appeared less than 2% when the slab thickness between 20 and 21cm. It is desirable that the slab thickness must be above 20-21cm. The reduction ratio of deflection is appeared greatly when the value of the span/thickness ratio is between 25 and 30. In conclusion, the steel layer depth and thickness had a little effect on deflection of the dynamic response, but had no effect on the steel layout angle.

This study describes development process of residential architectural space in the Richard Meier's residential works through chronological analysis. By analyzing house layout, floor plan, elevation, materials and colors and light entering of his residential works, changes in his architectural space has been studied. Richard Meier's early work is designed as three-dimensional shape, and places emphasis on geometric form. However, recently completed residential works by Richard Meier focuses on the horizontal sun shading louvers, which has ability. In addition, teak and a special UV protective glass are used to control natural environment. Through this research, it was found that Richard Meier has maintained his architectural language in terms of the design layout of the house and planar with colors that appear on the initial project. Using light input methods and materials used for active development, it was found that many design elements were applied and developed.

Based on travel literatures written by the Joseon literati, the different picture of seventeenth- and eighteenth-century Buseok monastery from the one today emerges. Not only do the buildings removed from the monastery today reappear, but the quite different way of the monastic operation comes to light. This observation leads to a speculation that the monastery was functionally and spatially divided into two territories; that of the Immeasurable life hall and of the Dharma hall. The Immeasurable life hall's precinct was built at the site open to the west providing a grand vista of mountainous area. This siting, originally having a close relation with the visualization such as the Sixteen contemplation, not simply gave such a special attraction that the first built architectural composition has lasted through the centuries to the late Joseon, but also granted to the Chwiweon pavilion located at the western side of the precinct a special meditative quality. As the monastery has suffered from a number of heavy duties in the Joseon period, the architectural attraction of the precinct was mobilized to promote the monastic identity as the legitimate monastery first built by Uisang, the founder of Hwaeom Buddhsim. Especially, the Chwiweon pavilion offered a mental space so that the literati might form an affirmative attitude toward the monastery and the monks. The Dharma hall's precinct was built based on the direct replication of the architectural layout presented in liturgy books for the Water and Land rite as well as the Vulture Peak rite. This layout is generally called the Court-type enclosed by four buildings, which has been widely fashioned in the late Joseon period. This characteristic gave to the Dharma hall precinct an arbitrary and anonymous quality, which helped not only avoid the tourism of the literati, but also secure the sacrality and ritual efficacy at occasions of Buddhist rites. This division of territories of the monastery can be understood as the strategic reaction from the monks in order to survive in the age of oppression against Buddhism. In result, the identity of Buseok monastery in the late Joseon was established as the Nine-rank sanctuary where Bodhisattvas permanently resided.

In Korea, special education for the gifted is being activated in school systems, and many researches regarding this special education are being conducted. However, despite its rich research on the programs of this special education, there are almost no research on the institutions layout and spatial design that can utilize them. Considering the heat for education of the present and the researches on education for the gifted so far, this tendency is likely to continue. To study space composition and interior architectural design of children's institution for the gifted, we studied the cases of 5 institutions located in Seoul and the following are the results. The research results are as followed. Most institutions for the gifted used most common and technical paint, wallpaper, and PVC for finishing materials. The colors should be carefully selected, too, so that it will increase inquisitiveness and interest of the children, which will develop into creative ability. In the cases studied, color of most walls and furnitures were not very distinctive: they were in light pastel and bright tone. And there were set of desks in many shapes so it can be put in different ways for different purposes. However, there were also desks that are commonly used at schools, which were limited in arranging in various ways. Most cases studied were located in general building and therefore, natural light source was limited. On the part of appliances, supplements should be made so that classes can be carried out using multimedia materials.

The purpose of this study is to suggest improved Special Instruction Classrooms(SIC) in terms of architectural planning based on the analysis of design characteristics and problems. For this study, SICs in 20 elementary schools located in Daegu were selected and investigated. The results of investigation showed that: first, the vertical separation type is mostly preferred for the layout of SICs; second, the top floor is preferred for the location of SICs. We suggest that first, each SIC should be located with consideration of the characteristics of subjects(); second, the degree of adjacency-room preference for each room should be taken into consideration for the zoning of the SICs(, ); finally, a direction for improvement for suitable architectural design of each SICs should be based on the feasibility of learning space().

The objective of the present study is the depth and layout optimizations of a single layer, high level radioactive waste repository in a discontinuous rock mass with special joint set arrangements. A single layer repository model, considering variations in the repository depths, pitches, and tunnel spacings, is used to analyze the thermomechanical interaction behavior. It is assumed that the repository is constructed in saturated granite with joints; the PWR spent fuel in a disposal canister is installed in a deposition drift which is then sealed with compacted bentonite; and the backfill material is filled in the repository tunnel. The decay heat generated by the high level radioactive wastes governs the thermomechanical behavior of the near field rock mass of the repository. The temperature and displacement behavior of the repository is influenced more by the pitch variations than the tunnel spacing and repository depth. However, the stress behavior is influenced more by the repository depth variations than the pitch and tunnel spacing. For the final selection of the tunnel spacing, pitch, and repository depth, other aspects such as the nuclide migration through a groundwater flow path, construction costs, operation costs, and so on should be considered.
