The construction supervisors of the public companies are usually responsible for process management, quality management, safety management, and many other various tasks that occur during construction project. Public companies such as Korea Highway Corporation have developed a framework and manual for management and supervision of construction projects. But, there has been the change of business environment such as increase of private investment project and the introduce of construction management system recently. It has been necessary for construction supervisor to streamline the current project management system in the owner's aspect in order to cope with the expected new challenges. Accordingly, this research has been investigated and analyzed the operation system between Korean supervisor and foreign supervisor in their public corporation. This research has suggested the advanced project management in their public corporation. Especially, this study has proposed the construction management manual for supervisors such as inspectors training, supervisors construction manual, and supervisors training road map.

With speeding up the process of being international municipality, the gravity of lacking parking lots in Shanghai urban area, which directly blocks the traffic in the city, has been revealed. This thesis analyses present automobiles parking capability and forecasts the future's needs for the city. To solve the problem, the concept could be to expand parking areas in city center recently to relax the tention and to do thoughtful planning in the near future on the foundation of fully consideration the trend. The municipal government has to set up policy properly, amplify regulations, strenthern the administration and open up a path to raise founds. Berween road system administration which is dynamic and parking lot system administration which is static, there are a knot on macroscopic meaning and an interference as well. The coordination of these two systems would be reflested on the effects of whole municipal traffic adminisration. Basically, public parking lots are city's foundal facilities, just like roads, bridges, etc. The main problems now in Shanghai are large parking space demands, insufficient facilities, cheap parking expenses comparing with the cost of parking lots construcion and poor administration. According to the forecast on social economy development, there will be 580 thousand automobiles in Shanghai by the year 2000, and the amount of private cars will increase greatly. The frequency of automobiles going out will be 1.45 million per day. Public parking lots being able to afford 105 thousand units are needed. To satisfy the demands, the recent aim of planning should be speed up the parking lots construction, the planning objective in next period should be developing reasonably and exceed the demands properly. In order to realize the planning objective, the government has to formulate correct policy and amplify administration regulations. The government has to adopt both administration and economy means, including charging parking people reasonably, collect necessary taxes, bringing the parking lots planning into general municipality planning, opening up an effective path to raise founds, such as set up founds for parking lots construction, issue bonds and stocks, get loans at home and abroad, etc.

Traditionally, a congestion charge based on first-best congestion pricing theory, namely, the theory of marginal cost pricing theory, is equal to the difference between marginal social cost and marginal private cost. It is charged on each link so as to derive a user equilibrium flow pattern to a system optimal one. Based on this theory this paper investigates on the characteristics of first-best congestion pricing of multiple user class on road with variable demand, and presents two methods for analysis of social and spatial equity. For these purposes, we study on the characteristics of first-best congestion pricing derived from system optimal in time and in monetary unit, and analyze equity from this congestion pricing with an example network.

The main purposes of this study were eliciting the planning contents and indices that is necessary to consider the physical part of public space, the side of service users and coherent side for improving public service. After then it analyzed the importance in both civil servants and practical officials side. For this public space planning topics and indicators by FGI (Focus Group Interview) derived through and through expert questionnaires Analytic hierarchy (AHP: Analytic Hierachy Process) were analyzed by conducting importance. A result, the priority of public space as a park planning index was found in the case of privately owned public space, public pedestrian pathways, public open space, public facilities land, the park is located, and the most important characteristics of the road, if the public transport association the most important thing is derived. In order to enhance the public good public space and location for easy access to the consideration of whether the plan should be. Therefore this work will be the fundamental materials to make some of farther policies related with the development of public interest of private-public spaces.

Urban style row-rise houses for rent have been supplied to the center of city from the 1950's first half The amount of stock is about 450,000 houses and occupies about 40％ in the private rented house. As for the structure, the 60％ of them is wooden-structure and the rest is non-wooden. Stocks of 57.5％ of the wooden-structure and 86％ of the non-wooden were built after 1981 years. It was 1981 years that the new earthquake-resistant standard was carried out, the improvement of stocks built before 1981 is necessary because those don't satisfy the present standard. To investigate the renovation possibility of urban style row-rise houses for rent, actual situation of two-story apartment at 2,4, and 5 Chome Taito-Ku in Tokyo was surveyed from July to November 2001. The number of building analyzed is 227 ridges among 234 ridges of the surveyed two-story building. 90％ of building analyzed is wooden structure. 1) The site of 88％ building surveyed is close to a road less than 4m width. It becomes the existing non-conformed building in the building construction act. It is impossible to make a renovation such as rebuilding, extension and remodeling because it requires the set back when renovating this type of non-conformed building, 2) The building built before 1981 is almost wooden-structure, and occupies 37％ of the building surveyed, and doesn't satisfy the present earthquake-resistant standard. An improvement of them is needed because the decrepitude of building proceeds. 3) 50％ of openings and 40％ of windows of the building surveyed doesn't use noncombustible materials. Though it becomes the existing non-conformed building, it can satisfy the present standard by replacing openings with noncombustible materials.

New towns and large multi-family housing complexes are being built in the capital region of Korea, with the goal of creating safe and pedestrian-friendly cities. Traffic accidents in such residential complexes, however, is on the rise, creating social problems. While there have been many previous studies on problems with pedestrian environment; there is a dearth of studies that take design-based approach to ensure safety in pedestrian environment within residential complexes. Therefore, this study aims to prevent traffic accidents by properly planning pedestrian environment within multi-family housing complexes, in addition to emphasizing theories related to planning safer pedestrian environment in general. This study found the following design directions required to improve the design theory of pedestrian safety in multi-family housing complexes: (1) Linking traffic facilities and residential complex spaces in Korea; (2) Considering implementation of United Kingdom road systems; (3) Establishing appropriate objectives for each residential complex based on case study. In response to these findings, the study selected the A84BL complex in Hwaseong Dongtan 2 Complex located in Dongtan-myeon, Hwaseong-si in Gyeonggi Province, Korea. Items that can be implemented, as well as spatial design directions, were discussed with a focus on private vehicles, pedestrians, and service vehicles.

The biotope network of Susung gu is characterized as dense residence zones forming its core that enable partial biotope in and around the residential zones. First, in district I, it is possible to make these zones connected to the third district. In district II, which is abundant in biotope, it is very important not to continue destoyi9ng the existing biotopes. In the case of district III, old residence zones have fill the severe gap between forests and the Sinchun river, through redevelopment, which covers more than 30% of the biotope area with large scaled linear residence areas. In the case of district IV, limited destruction of biotope and the improvement of nature areas were suggested as the alternative for preservation of biotopes. Consequently, in the construction of the biotope network in Su-sung gu, the maintenance of existing biotopes is required. Int he old residence zones, as redevelopment occurs, by maintaining biotope area of more than 30% and making the scale of residential complexes more than 1ha, it is possible for old residence zones to accomplish the role of providing important green spaces. In the case of newly developed residential zones, by reducing the rate of pavement of traffic conducts, utilizing small sized parks at the junctions and the plantation of trees along the corridors, the entire residence zones are able to accomplish the role of providing important green space. The problem houses and connecting the inner green space of the private houses with the green spaces of the streets in some areas. Futhermore, green spaces of forests must not be used for urban development. Dual planting on sidewalks, planting plots dispersed among streets and median strips must be established on road, too.

In this paper, we developed a vehicle control terminal using IoT and low-power long-distance communication (NB-IoT) technology. This system collects information on the location and status of a parked vehicle, and transmits the vehicle status to the vehicle owner's terminal in real time with low power to prevent vehicle theft, and in the case of a vehicle in motion, When primary information about the vehicle, such as an impact, is collected and transmitted to the server, the server analyzes the relevant data to generate secondary information on traffic congestion, road damage, and safety accidents. By sending it, you can know the exact arrival time of the vehicle at its destination. This terminal device is an IoT gateway for a vehicle and can be connected to various wired and wireless sensors inside the vehicle. In addition, the data collected from vehicle maintenance, efficient operation, and vehicles can be usefully used in the private or public sector.

In this paper, in order to study the relationship between the safety culture of highway management agencies and disaster reduction activities (BCMS), a measurement tool was identified through previous research on safety culture, and the validity of the measurement tool was confirmed through exploratory factor analysis. I want to check. The subjects of the study were workers belonging to disaster reduction activity management system certification organizations among highway management organizations. The highway management agencies are the Korea Expressway Corporation, which manages the functional continuity of national highways nationwide, and 8 of the 21 private road agencies that manage the functional continuity of the highways. The safety culture measurement tool is an indicator that measures safety culture factors, and is reorganized by the researcher based on survey items from previous studies, with management/manager safety values and attitudes, safety communication, safety education and training, and safety regulations/management system as subfactors. A total of 24 questions were comprised of the survey tool. As a result of the study, the result of exploratory factor analysis was that the safety culture scale was extracted into four factors based on theoretical grounds, and the total cumulative variance was 80.360%. When checking the questions for each factor, it was found that all the questions loaded on the factor that was originally intended to be measured. Factor 1 is management, factor 2 is safety, and factor 3 is communication., Factor 4 was named education. Number of questions: 4 management questions, 3 safety questions, communication It consisted of 4 questions and 2 education questions.
