  • With the rapid development of information and telecommunication technologies, the adoption of ubiquitous technologies is increasing for the realization of new effective u-City services. u-City is defined as a next-generation informatization city that can innovate a city's various functions, such as improving the welfare of the citizenry, ensuring safety based on systematic urban management, improving the quality of lives, and increasing convenience in city life, by merging cuttingedge information and telecommunication infrastructures and ubiquitous information services with urban space. There is therefore a need to recognize that a successful u-City implementation strategy involves developing the previous UIS into a ubiquitous technology-based UIS and integrating UIS's various urban informations with effective u-City services. In this paper, for UIS-based u-City implementation, the intelligent integration model of urban spatial information based on interoperability is proposed.

  • In this paper, the design methodology of information security is analyzed to implement the ubiquitous city (u-City). The definition, concept, and main u-services of u-City are presented. The main components, functio ns and offering services of u-City management center are presented, and the laws and network security requirements related to protect the personal information in collecting, processing, and exchanging are also analyzed. Three step security levels of Router/Switch, Firewall/VPN, and IPS are applied where main functions of in terception of abnormal packets($1^{st}$ level), access control for each service($2^{nd}$ level), and real-time network monitoring($3^{rd}$ level) are performed. Finally, application cases are presented to validate the security of personal information in providing the u-City services.

  • 이 연구는 u-City의 성공적 조성을 위해 u-서비스 공급자 측면과 수요자 측면의 요구를 충족할 수 있는 u-서비스 우선순위 선정에 관한 체계적 연구의 필요성에서 시작되었다. u-서비스 우선순위 모형개발을 위해 선행 연구를 토대로 수요자와 공급자의 서비스 결정 요인을 탐색적으로 도출하고, 전문가와의 브레인스토밍을 통해 u-서비스 결정의 확정적 요인을 도출하였다. 도출된 요인들을 계층분석(AHP)모형으로 설정하고, 1차 전문가 설문조사를 통해 요인별 가중치와 우선순위를 도출함으로써 공급자와 수요자를 고려한 u-서비스 우선순위 선정 모형을 제시하였다. 개발된 모형을 바탕으로 2차 전문가 설문조사를 통해 u-지역정보화에서 제시한 대구지역의 특화서비스를 평가하였다. 평가 결과 대구지역은 지역물류 지원서비스, 시각장애인 길안내 서비스, u-텔레매틱스 서비스가 상위권을 차지한 반면, u-지역정보화에서 제시한 안전방재지원서비스와 산업특화거리 등의 서비스는 중위권을 차지하고 있어 공급자 위주의 u-서비스 선정과는 차별성을 보였다. 개발된 u-서비스 우선순위선정 모형은 u-서비스 제공 및 사용의도에 기반한 모형으로 u-서비스 우선순위 선정을 체계적으로 지원할 수 있어 향후 성공적 u-City 조성에 기여할 수 있을 것이다.

  • U-City is the key element of the future knowledge-based society where every citizen will be benefited from the most advanced information technology. The following research reengineers the old process to define the rational and efficient process of the U-City construction project(BPR: Business Process Reengineering). In order to achieve the goal, identify and diagnose problem points, outline the improved plan, and readjust the managing system and process to propose better process. And Lastly, redefine the best efficient process by simple modeling using the UML(Unified Modeling Language). The goal of the systematic proposal is to make contributions to a base of the green growth to be the development of the Sustainable U-City.

  • 도심내 지속적인 차량증가에 따라 도시의 주차문제는 운전자에게 있어 과거부터 현재까지 여전히 불편함을 주고 있다. 이에 유비쿼터스 기술을 이용한 주차시스템이 활발히 연구중이며, 센서를 이용한 새로운 형태의 주차장이 생겨나고 있다. 따라서, 본 논문에서는 국내 사례 및 선행연구의 검토를 통해 시사점을 도출하였고, 더욱 더 발전된 모바일을 기반으로 한 유비쿼터스 기술을 적극 활용하여 능동적이고 개인 맞춤형의 통합 주차서비스가 가능한 지능형 u-Parking시스템을 제안하였으며, 개별 운영관리의 비효율성을 u-City의 통합운영센터와의 연계를 통하여 효율적 방법을 제시하였다. 또한 주차장 스마트 검색, 인터넷 주차장 예약제, 경로연계 맞춤형 정보제공 등 u-서비스 비즈니스 모델 제시를 통하여 효율성과 경제성을 확보방안을 마련하였다.

  • In recent year, the u-City construction projects which integrate IT technology into urban infrastructures are being pushed forward by many local governments. These projects contain various purposes in an aspect of regional economy : to reinforce a competitiveness of region by increasing efficiency of urban managements and to revitalize regional economy by stimulating the regional high-tech industries that related to u-City construction. In this context, regional economic impact assessment of u-City construction projects is particularly important because, it give us information about effectiveness of u-City construction policy as a stimulus of regional high-tech industries and the policy feasibility of u-City construction projects that can be a base of public projects. However, it is challenging to assess the impact of u-City projects on regional economy properly due to a lack of understanding about industrial classification, and specific industrial inputs related to u-City construction. In this study, we suggest u-City industrial classifications, and specific-industrial inputs induced by u-City construction projects based on associated legislations, business report for a u-City construction, and results from previous studies. Using these classification and industrial input, we also investigate the regional economic impacts of a u-City construction project in Wha-sung and Dong-tan cities employing Input-output analysis. The empirical results suggests that u-City industries have relatively high in production inducement, and value added inducement compared to input of other industrial sectors. These results indicate that regional economic impact of a Wha-sung and Dong-tan u-City construction project are relatively high, but economic impacts of u-City construction projects vary according to the regional industrial structure, and the specific expense accounts of u-City construction projects.

  • It is a fact that we are yet to recognize and sense the U-City even though the business of U-City construction has been started many years ago. One of the causes is that UCity was thoughtlessly developed in the industry-centered environment for a tangible achievement, despite of need on more systematic development and organized management. Fortunately, it is expected that the most part of the situation will be solved, since "laws on the construction of the ubiquitous city" for planning, construction and management has been promulgated on March, and U-City project will be systematically promoted by the related laws from now. Therefore, intention of this study is the sustainable development of the U-City by analyzing the previous process and problems of the U-City Construction project of local governments and reengineering U-City construction project process in accordance with new laws, using the BPR methodology.

  • This research dealt with the methodological procedures of ubiquitous sensor networks, applying to urban ground facilities. Recently Korean government established a guide, "u-City IT Infra guide v1.0" when promoting u-City implement projects. This guide conceptually included general processes about u-City mainframe in overall, but its guidance could not lead the detailed procedures and methods for specific ground facility. Therefore, this research proposed the details of the procedure for the intelligence of facilities after reviewing the existing procedures for ubiquitous city. Newly proposed procedure for the intelligence of facilities was consisted of selection of facility and sensors for intelligence, setting a level for intelligence, and suggestion of service model for the selected facility.

  • 2009년 현재 기완료된 바 있는 화성 동탄 신도시를 시작으로 국내 12개의 u-city가 건설 추진 중에 있다. 또한 39개의 지구가 추진예정 중에 있으며 더욱 많은 지자체들이 u-city사업에 관심을 가지고 있다. 이렇듯 지대한 관심을 받고 있는 u-city의 구성요소 중 핵심이라 할 수 있는 도시통합운영센터는 도시정보를 효율적으로 취합하고 정보서비스를 제공하는 요소라 할 수 있으며, 그 구축방안에 대한 연구들이 활발히 이루어지고 있다. 하지만 도시의 여러 특성에 따라 적합한 센터의 구축방안에 대한 연구는 거의 이루어지고 있지 않은 실정이다. 특히 도시개발 유형과 관련하여 신도시를 건설하면서 u-city를 구축하는 경우 도시의 기반시설물 구축과 함께 u-city시설물 구축이 동시에 가능하지만 기존 도시의 경우 이미 구축되어 있는 도시기반 시설물에 u-city구축을 위한 시설물과 관련 기술을 적용해야 하는 차이점이 있다. 따라서 이러한 차이로 인해 각 유형의 도시통합운영센터 구축 방안에도 차이가 있을 수밖에 없다. 이에 이 연구에서는 우선 여러 가지 도시특성 중 개발 유형에 따라 도시의 유형을 구분하고 이를 중심으로 도시통합운영센터의 구축 시 고려해야할 점에 대해 살펴본다.
