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

There are two main halls in the Main Palace of the Koryo Dyansty in the 11th and 12th century. One, named Hoekyongjeon, was served only for special ceremony ; hundred Buddhist priests' sermons or receiption of Chinese emperor's letters. The other one, Kondukjeon, was used as ordinary throne hall. The ordinary throne hall was built when the palace was erected at the beginning era of the Koryo Danasty, while the special ceremony hall built after the reconstruction in the 11th century. The throne hall was located at northwest side of the special ceremony hall. Audience chamber and King's bedroom were located at west and northwest side of the throne hall. The basic layout of the Palace showed unsymmetrical shape. It seemed mainly effected by its undulating terraine. The acess road from main gate to the throne hall showed zigzag way, by following a stream penetrating the site obliquely, It could be said that the Main Palace of the Koryo Danasty achieved its originality on the aspect of unsymmetrical layout and zigzag acess road, which was not found in the former palaces.

This study aims to investigate the mechanism that analysis of the layout-structure of the Traditional Village Oeam. It can identify through the division of area, the properties of layout residential type, the relationship between buildings and roads and location of buildings and a gate. Traditional Folk Village is our precious cultural heritage. However, now is time for our disappearing heritage due to the indiscriminate development. This study will good references for residential Complex in modern society. As a result of this study road in the center of village is divided into two areas. The road and stream plays an important role in the housing layout and composition of the village. Oeam village houses are separated by scale as large, middle, small scale housing. The courty yard is formed widely through a various of housing plan. So that ventilation and light is favorable even if the main house is high. Each house has the individuality with avoiding the village roads and using the byroads and stone wall. Therefore, each house can protect the privacy of houses.

To meet the soaring demand recently, South Korea big shipbuilders are examining two things. One is new investment in plant and equipment. The other is replacement of production resources. Considering plant & equipment investment and replacement of production resources, even if actual production ability would be enough, the real output could be affected by limitation of logistics with lack of analysis. As we set up big shipyard in virtual space, we could perform actual production by using confirm production plan in virtual space. We've analyzed the load of block stock, load of road and load of transporter for logistics effects are followed by production increase. This research is to determine the possible problems of those analyzed results and to present the resolution using the current layout. And then modified yard layout, we reanalyzed previous three logistics effects. This simulation model could help administrator to make rational decision for changing yard layout.

PURPOSES: Road Design Consistency Evaluation can guarantee road alignments with safety factors, however it can be hard work to deal with general car accident factors in only this evaluation index. Ideal Road Design Consistency Evaluation is show the mutual balance of road alignment and human factors with a variety of factors for road safety. METHODS: This study carried out overall road safety evaluations which are methods of running speeding consistency and car platoon safety analysis (driver's behaviors factors) as well. RESULTS: Out of 13 sections in a experimental road layout, safety factors of 8 sections showed 'Good' or 'Fair' status. However, 'Poor' results were found out in 5 sections. Particularly, it showed the different outcomes among the 4 evaluation methods used in this study. CONCLUSIONS: Road safety countermeasures were proposed for the potentially dangerous sections in road which failed to identify in the other methods. This study will contribute toward future study of more reliable Road Design Consistency Evaluation in the future for road safety.

Sign system is one of the most widely used guide media in scenic spots. It plays vital role in introducing cultural values of destinations to tourists with better visit experience. The purpose of this study is to derive the influence factors of the sign system of Mount Tai scenic area for tourists, analyze the satisfaction of tourists, and provide suggestions for the sign system of Mount Tai Mountaineering Road to improve tourists' satisfaction in the future. The evaluation items of Mount Tai Mountaineering Road sign system were derived from the previous studies and then subdivided comprehensively. Survey by questionnaires was carried out to obtain the influence factors. In order to understand the satisfaction degree of tourists, fuzzy comprehensive evaluation was implemented. The research results of this study are summarized as follows. First, four influence factors of the sign system on Mountaineering Road of Mount Tai were concluded as the interpretation content, appearance modeling, interpretation methods and layout management. Second, the order of weight values of influence factors was the interpretation content, appearance modeling, interpretation methods and layout management respectively from high to low, which means that tourists paid more attention to practicality and aesthetics. Third, the satisfaction degree of the tourists on the sign system was different. The satisfaction level for the three factors (interpretation content, appearance modeling, layout management) was good, while the satisfaction for interpretation method was medium. The reason was that it failed to deepen the understanding of tourists on the natural and cultural values of Mount Tai Mountaineering Road. These results indicate great significance to provide theoretical basis for the later readjustment and design of the sign system and to improve the overall satisfaction of tourists on tourism experience.

Rapid urbanization and population increasing are making a high-rise residential building and high-density residential area. According to spacial concentration of population is occurred road traffic noise problem. Now we are popularly using almost only noise barrier installation, but it makes many disfunctions such as poor landscape, low noise barrier performance and crimes. The purpose of this research is to figure out which is best method one the traffic noise management. Alternative are composed to building layout type ($30^{\circ},\;90^{\circ},\;180^{\circ}$), separation between road and residential building, noise barrier types(noise barrier only, noise barrier and forests and etc). The noise barrier are shown to reduce barrier and building layout angle $30^{\circ}$ position is the best comparing with horizontal and vertical layouts. The gab distance is decreased approximately noise level 5dB(A). We figured out there are noise important method except noise barrier wall and it was analyzed how much decreased. This can be very useful before making a road planning and residential building design.

This study was aimed at suggest a proper planning method to select a optimal forest road network in mountains forest using GIS(Geographic Information System). To examine the field applicability, the method was applied to the National Forest at Mt. Kumsan in Namhae-gun, Gyungsangnam-do. The main results from altogether six alternative road route plans were derived from these criteria obtained the alternative route plan No.2 has two layout criteria, longitudinal gradient and earth work volume, and it showed similar pattern of existing forest road network which was designed mainly ground slope and longitudinal gradient. The alternative route plan No.6 has four criteria, longitudinal gradient, earth work volume, investment effect and landscape impact. It was different for the lowest forest road density among the alternatives and the pattern of the forest road layout was radial form, which was also quite different to other alternatives. For optimal forest road network planning, GIS provide the efficient and resonable solutions for decision making to provide the support for evaluation about various alternative road networks. If detailed inventory and relevant data are provided and also clear and objective indicators for evaluations are set up, it could be applied to preliminary analysis and detail planning stage to prevent undesirable effect such the land slide and soil erosion due to inadequate planning for forest road network.

The purpose of this study is to examine if orientation, location of entrance, court yard of existing old houses are consistently maintained when houses are newly built fitting the changed lots system, and the changed road system for Topdong 'Yangdalmal' in the existing old settlements in old center Cheongju. The lots was spilt up into 15 lots in 1913, 38 lots in 1968, and 75 lots in 2010. Among them, The lots maintained are 19 lots and the lots subdivided are 56 lots. 12 houses are newly built among the 19 shape-maintained lots and 41 houses are newly built among the 56 split up lots. Most of the new houses have south-facing orientation. Main entrance near the old road keeps the direction of the previous entry. Houses built in 1970s and 1980s keep their original court yards but they are disappearing year by year by new type of houses in 1990s.

A user - oriented computer model to aid designing forest road is developed to release the burden by increasing efficiency of time - consuming and laborious road design works. In this paper, the structures and functions of the model are discussed. The model consists of functional modules : 1)input module to treat survey data and design criteria ; 2)road design module to generate preliminary road layout, horizontal and vertical curvatures and curve widening ; 3)earthwork analysis module to determine the economic mass movement ; 4)report writer module to produce hard copies of engineering drawings for plan views, cross - sections and profiles, earthwork calculation sheets and mass movement diagrams. In addition, the report writer also provides the information on earthwork disturbance along the cut and - fill slopes. The modules are designed to be fully - integrated to enable the users to perform engineering analyses and evaluate design alternatives in a series of road - design procedures.
