With an increasing number of cars in Korea, the government is constantly providing roads and their related facilities. However the fundamental problems of cities like the structure of cities and the environment of roads make the traffic congestion of downtowns. To solve this problem the construction of toll roads such as tunnels and bridges is increasing but use rates of drivers is low. With more tolls required, less persons will use the roads. Thus this study is to consider offering discounted charges when using the two or more toll roads together. This study analyzes the impact that discounted charges would bring to the demand. In the meantime we looks into what the proper range should be for the discount. The results of this study are expected to be used as basis for the introduction of a discount system in the future.

Information users depend more and more on portal sites for Internet navigation. These circumstances are reflected in academic information market especially. As the path of contacting public knowledge information, many institutions of information creation and services are collaborating with portal sites. At this point in time, it is necessary to consider linking libraries services with portal sites. Especially university libraries which have been recognized as private facilities of each university must to be considered as public facilities of local community. So it is desirable to develop method for linking university library services with portal sites for revitalizing university library services. This paper presents methods linking library OPACs with portal sites, through surveying oversea's cases and situation of domestic portal sites.

Considering the traffic condition of railroad 'KTX' links to lack of service's punctuality in nation's small/ medium cities, design guidelines with practical railroad transportation policies in terms of convenient railroadbus connection and improving comfortable ride is suggested. Following the guideline and policies, operational requirements of current railroad-bus connection system, the system's design consideration, and transportation policies and laws in relation to the bus operating companies should be analyzed to decide the practicality of the railroad-bus connecting infrastructure. Also, in order to achieve practical railroad-bus connection, connecting buses' design guideline is combined with suggested optimization method of the practicality transportation system. Lastly, the design guideline of buses as 'links,' and railroad transportation policies concerning the operation of connecting bus system for nation's small/medium cities are suggested.

Due to have been more keen in East-North Asia Hub Port competition, to be accelerated Busan New Port development, and to result to supply excess position, Busan port has been confronted by many problems. Also, as facilities of North Port is old, it is impossible to secure 16m depth of water at North Port, and North Port redevelopment is being, container traffic of North Port is accelerated to shift at New Port. Therefore, it. is time to seek for connection growth plan of succeeding together-Busan North & New Port as soon as possible. Connection growth plan of succeeding together-Busan North & New Port is focused, as follows. First, it is required to set up model for connection growth plan of succeeding together-Busan North & New Port. It is valid to specialize for ULCC, to promote to global port at New Port, and it is effective to focus on feeder service and general cargo handling, and to include most space to North Port redevelopment. Second, through port function reorganization, it is required to create a synergy by port function clustering. Third, through effective connection traffic network expansion for moving T/S cargo effectively, it is required to develop Busan Port for T/S cargo-focused port. Fourth, it is required to develop port hinterland logistics zone for creating container traffic through connection development of New Port-BJFEZ. Finally, it is required to build SCM system for creating container traffic among shipper, carrier, freight forwarder and related institution.

Increase of delivery effect of pollutant loads and surface runoff due to urbanization of catchment area results in serious environmental problems in receiving urban streams. This study aims to develop integrated stormwater management system to assist efficient urban stream flow and water quality control using information from the Storm Water Management Model (SWMM), real time water level and quality monitoring system and remote or automatic treatment facility control system. Based on field observations in the study site, most of the pollutant loads are flushed within 4 hours of the rainfall event. SWMM simulation results indicates that the treatment system can store up to 6 mm of cumulative rainfall in the study catchment area, and this means any type of normal rainfall situation can be treated using the system. Relationship between rainfall amount and fill time were developed for various rainfall duration for operation of stormwater treatment system in this study. This study can further provide inputs of river water quality model and thus can effectively assist integrated water resources management in urban catchment and streams.

Urban infrastructure is a core of urban growth management which concerns with location, time and costs of development. Despite an inevitable link between development density and infrastructure capacity in urban areas, little study have been performed. For this reason, development activities are undergone without any clear evidence or analysis. The main purposes of this paper are to build subject maps of urban infrastructure capacity which illustrate the level of education service and road capacity, and to give reference standard for development decision at given location. For these purposes, the case study of the high-rise multi-purpose buildings in Daegu metropolitan city is performed. The main findings are follows. First, road ratio is high in the CBD and its surrounding areas as well as rural area, and low in areas of manufacturing, parks and military use. Second, educational facility, represented by the number of student per classroom of elementary school, is fairly abundant across the city, especially in the CBD and rural areas. Third, the high-rise multi-purpose buildings have been built in population-losing infrastructure-abundant areas, in general. Based on these results, this study concludes that the high-rise multi-purpose buildings may induce population-inflow and have low possibility to bring about overly dense developments.

The South Korean government is looking for a solution to the ever-growing problems of traffic congestion, and surging international oil prices: the use of the humble bicycle to get to places. However, Many people feel inconvenient using bicycle because of the insufficient bicycle infrastructure and lack of the safety and connectivity between existing pathways. In this study, bicycle level of service model using ordered probit model is developed considering safety, convenience, connectivity, and factors that affect bicycle LOS. The ordered probit model would be recommended for the research which relates in choice, preference and strength etc. Bicycle level of service criteria is calculated by applying this model reflecting bicyclist's point of view. The model which develops from this research which accomplishes a bicycle level of service evaluation and represent alternative solution to encourage bicyclist. It is believed that the proposed model would be greatly utilized in bicycle network planning, bicycle road and facility alternatives testing, projects funding priority.

This study examined the present condition of the closed elementary school in the Yeongi province, where much of the area will be transformed into the city of Se-Jong, and suggested the renewal plan in the future. Among the twelve(12) schools, eight(8) that have transferred to private sectors were analyzed in respect to lot size, present usage, surroundings, means of approach, and distance from the most populated area, ect.. Additionally, interview with the management official of school board was taken in place. The findings include: two(2) schools that are located nearer then others to the newly-born city can be rehabilitated as educational facility, such as training institute and cultural experience place. Other six(6) schools can be utilized as senior citizens' center, community center, medical substation, hobby farm, or even community warehouse.

"재난 및 안전관리기본법"에서는 재난발생의 위험이 높거나 재난예방을 위하여 계속적으로 관리할 필요가 있다고 인정되는 시설 및 지역을 특정관리대상시설로 지정 관리하고 있다. 그러나 특정관리대상시설의 종류가 다양하고, 양이 방대하며, 상세 안전관련 내용이 개별법에 따라 관리됨에 따라 종합적인 안전관리가 어렵다. 본 연구에서는 특정관리대상시설의 종합적인 안전관리시스템을 구축하기 위하여 "소방시설 설치유지 및 안전관리에 관한 법률"에서 규정하고 있는 특정소방대상물의 소방검사제도를 살펴보고 이를 통하여 각 전문분야 시스템과 연계한 종합안전관리시스템 구축방안을 제시하고자 한다.
