This study analyzes areas, traffic lines and characteristics of block of traditional villages in order to suggest how to build urban village in the way that can solve problems occurring in residential areas these days. The study showed the following results: 1) Traditional villages have definite boundary and entrance, and the community area for the villages is close to the entrance to encourage community activities of villagers. 2) With an access in the form of a blind alley branched from the main road, traditional villages form a small-sized clustering and encourage community activities in a natural way. 3) Formed of block with a pattern of net, blind alley or standing in a line on both sides, traditional villages help residents to form close relations between. These findings suggest that for building desirable urban villages, 1) they should have definite boundary, 2) size and location of community area should be determined in the way to activate community activities of residents, 3) roads inside the village should have branched form rather than standardized check pattern so that small-sized clustering could be formed along the branched inner roads, and 4) clustering in villages should be arranged in a line on both sides or in the form of a blind alley giving consideration to the length and width of roads. The roads should be also of a closed type so that residents could create strong bonds with their neighbors.

This research aims to find the issues and explore policy agenda of contributed acceptance of urban renewal project. Through the analysis of urban renewal project in Seoul, three isssues was found as follows. Firstly, the ratio of contributed acceptance in each district was quite different. Secondly, the donated land was scattered around whole project area. Thirdly, infrastructures are not constructed until all renewal projects were implemented. For this issues, this research proposed that a proper standard of the ratio of contributed acceptance is needed and land donation should be designated to adjacent lot or block. Also public support should be for developing urban capacity and completing infrastructure.

This study measured temperatures and albedos of urban surfaces for different colors and materials during summer, and calculated the energy budget over different urban surfaces to find out the thermal performance affecting the heat built-up. The study selected six surface colors and 13 materials common in urban landscape. Their surface temperatures (Ts) and albedos were measured at a given time interval in the daytime from June to August. Average Ts over summer season for asphalt-colored brick was $4.0^{\circ}C$ higher than that for light red-colored one and $9.7^{\circ}C$ higher than that for white-colored one. The Ts for artificial surface materials of asphalt paving, brown brick wall, and green concrete wall was $6.0^{\circ}C$ higher than that for natural and semi-natural ones of grass, grassy block, and planted concrete wall. There was the greatest difference of $16.3^{\circ}C$ at midafternoon in the Ts between asphalt paving and planted concrete wall. Average albedo over summer season of surface materials ranged from 0.08 for asphalt paving to 0.67 for white concrete wall. This difference in the albedo was associated with a maximum of $15.7^{\circ}C$ difference at midafternoon in the Ts. Increasing the albedo by 0.1 (from 0.22 to 0.32) reduced the Ts by about $1.3^{\circ}C$. Average storage heat at midday by natural and semi-natural surfaces of grass and grassy block was about 10% lower than that by artificial ones of asphalt, light-red brick, and concrete. Reflected radiation, which ultimately contributes to heating the urban atmosphere, was 3.7 times greater for light-red brick and concrete surfaces than for asphalt surface. Thus, surfaces with in-between tone and color are more effective than dark- or white-colored ones, and natural or semi-natural surfaces are much greater than artificial ones in improving the urban thermal environment. This study provides new information on correlation between Ts and air temperature, relationship between albedo and Ts, and the energy budget.

A fast running model comprising the climate change effects is proposed for urban heat environment simulations so as to be used in urban heat island studies and/or the urban planning practices. By combining Hot City Model, a high resolution urban temperature prediction model utilizing the Lagrangian particle tracing technique, and the numerical weather simulation data which are constructed up to year of 2100 under the climate change scenarios, an efficient model is constructed for simulating the future urban heat environments. It is applicable to whole city as well as to a small block area of an urban region, with the computation time being relatively short, requiring the practically manageable amount of the computational resources. The heat environments of the entire metropolitan Seoul area in South Korea are investigated with the aid of the model for the present time and for the future. The results showed that the urban temperature gradually increase up to a significant level in the future. The possible effects of green roofs on the buildings are also studied, and we observe that green roofs don't lower the urban temperature efficiently while making the temperature fields become more homogeneous.

Unsatisfactory urban walking environment stresses urban residents, and may cause mental illness and chronic diseases by reducing walking activities. Therefore, establishing a high-quality walking environment that can promote walking activities in urban residents has emerged as an important issue. The walking environment consists of various components, such as trees, stairs, streetlights, benches, signs, fences, and facilities, and it is essential to understand which components and their settings act as satisfiers or dissatisfiers for pedestrians, to create a better quality walking environment. Therefore, this study investigated pedestrian satisfaction and dissatisfaction as a function of various environmental components through a survey using walking environment images. The results revealed that most of the walking environment components except the braille block and treezone exhibited significant correlations with pedestrian satisfaction. Particularly, safety-related component (e.g., adjacent roads, parked cars, traffic cushions, and car separation), and landscape-related components (e.g., trees and green), as well as the material settings of landscape facilities (e.g., wooden fences, benches, stairs, and walkway surfaces) correlated with pedestrian satisfaction. The results of this study can contribute to the extraction of useful features to evaluate pedestrian satisfaction as a function of the walking environment. The research outcome is expected to assist in the effective arrangement of walking environment components and their settings, which will ultimately contribute to significantly satisfactory walking environment and encourage walking activities.

The train control and monitoring system(TCMS) is an on board computer system in railway vehicles performing the control, supervisory and diagnostic functions of the complete train. This system replaces a lot of hardwired relays and minimizes the necessaries vehicle wiring thus increasing the reliability of the train. In this paper, we proposed a software design technique of TCMS using CASE tool (SAO+). The TCMS functions are implemented in software easily programmed, using a functional block, graphic programming language. We applied the compressor air module to a case study.

본 연구는 조선시대 읍치로부터 성장한 지방 소도읍의 하나인 고산을 대상으로 형태학적 개념과 연계하여 도시의 형성 발달과정에서 나타나는 형태구조와 도시평면 변화과정을 시계열적으로 분석해보고 시기별 형태특성을 도출해보고자 하는데 목적이 있다. 본 연구에서는 고산의 도시형태 분석을 위하여 콘젠과 카니지아가 설정한 도시형태 분석개념을 토대로 형태구조, 도시평면, 경로체계, 개발규정선, 전이지대, 중심지구, 평면단위, 형태시기, 브레이크 포인트, 자투리필지, 유휴지, 사유화 등의 개념을 도입하였다. 고산현시대에 골격이 형성된 고산의 도시형태 변천과정에는 도시형태 형성-구시가(kernel)의 형태구조 해체 재편-중심지구(epidome district)의 형성 발달-확장형 충진-중심지구 확장 재편으로 이어지는 순환적 사이클이 존재하고 있다. 공공사업은 고산의 형태구조와 도시평면의 변화를 주도하는 요인으로 작용하였다. 초기 단계 고산의 형태적 변화과정에는 간선경로로서 구시가(kernel)을 관통하며 개설된 신작로(고산로)와 이를 연결하는 계획로가 중요한 영향을 미치고 있다. 신작로 개설을 계기로 T(십(十))자형 골격도로체계를 바탕으로 구시가의 대부분을 점유하고 있던 관아시설구역의 평면단위가 소블록 단위의 개방형 평면단위로 전이되었다. 이와 더불어 신작로와 시장 경계도로를 따라 상가가 들어서면서 선형의 평면단위를 지니는 노선상가와 시장이 어우러진 근대적 중심지구를 형성하게 되었다.
