  • For assessment of U-Eco City technologies, more concrete definition of those technologies are required. However, almost researches defined technologies as conceptually and even cannot include all of them. In this sense, the purpose of this study is to deduct assessing items for specifying applying priority of U-Eco City technologies. We performed the research by 3 steps. Firstly, we deduct assessing items of the technologies by researching their advance process. After then, we compensate the defect of those items through documentary research and made a periodic table about core technologies that can be useful for deducting long-term items. The assessing items what are deducted as a result of this study can be applied to the selection of technology, and will be useful to construct more objective and systematized U-Eco City. Furthermore, if assessment frame about technologies and services is developed from this research, it gives to us probability that standardized process of U-Eco City construction can be established.

  • KUbiquitous city(U-City) is a recent trend in urban planning and management across the globe. Currently, several typologies were developed and presented classifying U-City services, but validation research of these typologies are scarce. In this study, efforts were made to qualitatively validate the usability and practicality of a typology of u-city services. Using 228 U-City services identified in previous studies, classifying exercises were conducted against a typology. Three experts were involved in this expert heuristic exercise, against a most popularly used and comprehensive typology of U-City services. Findings indicates that the selected typology is high on comprehensive exhaustiveness, and empirical applicability while low on mutual exclusivity, simplicity and theoretical contribution. Implications for the typology improvement are suggested followed by limitations and directions for further research.

  • U-City 공간계획 및 설계기술개발연구는 그 동안 서비스와 정보통신기술(ICTs)을 중심으로 다루어졌던 U-City추진의 한계를 극복하고 도시공간에 기반한 U-City 구축과 실증을 통해 저비용 고효율의 미래 도시공간을 구현하고, 기존 도시의 문제 해결과 도시의 효율적 운영관리의 필요성 등에 따라 공간적 측면에서의 U-City 구축을 통해 국내 대표의 건설브랜드인 U-City선도화와 종주국으로서의 위상을 강화하기 위한 U-City 창조공간 계획 및 설계 기법을 연구하고자 한다. 본 연구를 위해서는 국내외 관련 문헌조사, 사례조사를 중심으로 연구를 진행하고 있으며, 도시 공간단위별로Prototype을 구축하고 실제 사례도시(Test Bed)를 선정하여 연구결과를 적용해 보고 효과를 검증하는 방법으로 연구 내용의 내실화를 기하고 있다. 본 연구개발사업을 통해서 도출된 결과물을 통해서는 도시민이 체감할 수 있는 U-City 구현을 통해 시민이 체감할 수 있는 U-City 보급과 확산으로 국내 고유의 대표건설브랜드로서 U-City의 대내외적 경쟁력을 확보하고, 침체된 건설경기 활성화 등에 기여할 수 있을 것이라 판단된다.

  • This study examined correlations between U-Service for U-City and assessment indicators for urban competitiveness. The results of this study show that U-Service is used as a means of strengthening urban competitiveness in six types of cities, despite the differences in degree of contribution. The proper use of U-Service in Safety & Health City and Vitality (Economy) City has significantly contributed to strengthening the competitiveness of such cities. Of the assessment items for urban competitiveness, common items and Culture City type show that U-Service has not contributed much to strengthening urban competitiveness. The analysis shows that because common items are part of the assessment items for urban policies, these items are not suitable to the character of a U-City that implements U-Service through intelligent physical facilities. On the other hand, U-Service related to the Culture City type is relatively less developed. This study found out that U-Service could be used to reinforce urban competitiveness.

  • U-City includes various information devices and network techniques, which connect among several information devices. Integrated Management Center, which is the core element of u-City, is designed to manage all services of u-City and carry out the control function for a city. Accordingly, u-City needs the methods of user authentication and security, so these methods must be implemented to integrated management center. This paper is devoted to describe some conventional authentication techniques, and authentication methods and procedures that may be available to u-City network context. Proposed u-City integrated authentication model assigns IP to only right user after authenticating information terminals and users in u-City and authorizes users according to the policy, so this model plays an important role for the security of integrated management center.

  • The purpose of this paper is to analyze the implementation of the GIS infrastructure systems for the u-City, GIS base u-City represents spatial information derived fields, such as geographical distribution of the urban boundaries, physical configuration of the urban locations and cultural characteristics of the urban history. These three aspects relate to urban infrastructure systems implementation, urban monitoring center implementation, and spatial database implementation. In terms of the GIS based u-Ci쇼 urban infrastructure implementation systems, the u-City depends on IT contents and spatial features. IT contents are strongly related to IT839 strategy due to the national agenda is "u-Korea". GIS should contribute to u-City construction through the spatial analyses methods. For these methods various GIS functions will guide to u-City's distribution, location, and characteristics of urbanization. The infrastructure consists of road and road facilities, underground facilities, related agencies facilities, dispatch systems, environmental systems, and urban planning. These six units of the urban infrastructures have spatial databases that consist of spatial configuration, such as dots, lines, and polygons in order to draw the spatial distribution of the u-City GIS based u-City urban infrastructure implementation systems should deal with It convergence to generate fusion affects.

  • By the time the interest on the u-City is continuously growing as a test bed for verifying the potentials of ubiquitous convergence industries, research on the u-Safety gradually increases as well, as a typical service and application area of u-City. Like the other service areas of u-City, in order to provide u-Safety services smoothly, it is crucial to integrally connect u-City services and infrastructures that have operated under distributed environment. In this study, we suggest an approach for design of u-Safety service and monitoring architecture by combing CIM/WBEM standard with GMA. CIM/WBEM and GMA are broadly applied in the distributed resource monitoring environment and are widely recognized as data acquisition architecture under massive monitoring data volumes respectively. Considering the growing research needs for standardization and extension of u-City service infrastructure, it is expected that our integrated infrastructure model will be used as a reference model for effective integration of distributed resources with newly added services.

  • A law and enforcement ordinance related to "ubiquitous city" (U-city) has been announced officially in Korea and practical standardization which is connected with U-city is in progress. The U-city defines citywide service over a city providing its infrastructure. The key facilities of U-city include intelligent equipments, networks, and operational facilities. Especially, the main focus of them is the intelligent equipments that are defined as facilities being applied to information technology. However, U-city has not been provided with standards related to actual construction of intelligent equipments so far. In this article, we survey standards for intelligent equipments for existing infrastructure and U-city's services.

  • u-방재City는 첨단 IT 인프라를 기반으로 유비쿼터스기술과 단위서비스를 활용하여 시민이 안전하고 편안하게 생활할 수 있도록 재난으로부터의 피해를 최소화한 도시이며, u-방재City 서비스란 도시의 지능화된 기반시설과 정보통신망을 활용하여 재난상황을 상시 모니터링하고, 이를 통해 재난의 사전 예방과 상황 발생 시 신속한 대응이 가능하도록 하는 서비스로 정의된다. 이러한 u-방재City 서비스는 지역간 서비스간 상호 운용성 확보가 매우 중요하며 국가재난관리의 큰 틀 내에서 추진되어야 하는데, 이를 위해서는 지역의 재난발생 특성과 서비스 수요 및 인프라 여건 등을 종합적으로 조사 분석하여 서비스 모델을 개발하여야 한다. 본연구는 u-방재City 서비스의 체계적인 개발과 효율적인 운영을 위해 지역의 재난발생 특성과 재난관리 업무현황, 서비스 제공을 위한 인프라 여건, 서비스 수요 및 요구사항 등을 조사 분석하고, 이를 토대로 u-방재City 서비스 개발 및 운영 방향을 제시함을 목적으로 한다.
