본 연구에서는 u-Eco City 건설을 위한 u-City 기술 연구의 첫걸음으로서 기반시설 관점에서 u-City기술을 분류하고자 한다. 이는 u-City를 구현할 때 기반시설에 u-City기술을 접목함으로써 u-City서비스를 실현할 수 있기 때문에 의미가 있다. 즉, "유비쿼터스 도시건설 등에 관한 법률"에서 언급하고 있는 u-기반시설의 개념을 도입하여 기술을 분류함으로써 서비스-기술-기반시설의 연계성을 명확하게 파악할 수 있다. 본 연구에서 제시하고자하는 u-City 기술의 분류는 u-City기술의 범위를 정하고, 추후 기술개발의 전략적 목표 설정 및 기술전략 수립의 기초자료로써 활용될 수 있으리라 기대된다.

In recent years, our society, because of the arrival of a new paradigm according to the rapid changes in ICT has entered into future smart society and the ubiquitous era. So it can be a notable turning point in the city and administrative spatial informatization, aspects of the era change. Therefore, this study was to derive a desirable vision for the city of Busan Centum City Informatization in the dream of leading global smart city of Busan by applying 'scenario planning' as a foresight method. Soon this study derived a successful local informatization strategy for Centum City in Busan. It proposed the use of the administrative aspects of information with spatial informatization as metadata information. Also this study explored the future leadership strategy of Busan Centum City in smart society. Eventually in 2030 to around, In order to still remain Busan Centum City as a leading ICT smart city, this study suggested the following strategy. It is important to increase the satisfaction of citizen services through the use of the administrative aspects of information with spatial informatization as metadata information for urban information system.

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.

Recently, a lot of nations are establish and researches the u-City which ubiquitous technology based city, and u-City Management Center(UMC) is also establish and researches. Technical researches of UMC are increasing. However, administrator privilege management researches for UMC is not enough. If we don't manage to administrator privilege who can access and control all of information in UMC, security problems will be occurs. Therefore, in this paper, analyses of administrator privilege management security problems, and proposed administrator privilege management system classification.

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.

Recently, there are many researches to realize context-awareness service that recognizes surrounding environments as context and provide the citizens with pervasive convenience based on ubiquitous computing technology. In the u-City, various sensors collect information as context, and citizens will receive various context-awareness service, making use of their wireless and mobile devices and the infrastructures of the u-City. We designed ontology that is useful to structure information of sensor or device that is linked to networks and use OWL (Web Ontology Language) that can express information of mutual relation and partial situation. And we propose a context-aware reasoning system for personalized u-City services based on collected context information and user's intention.

Informational urbanism is a new research area in information science. In this study, art history joins informational urbanism: Are digital artworks in public urban spaces recognized as essential assets of a smart city? We employed case study research, working with the example of the huge digital media façade of the Arthouse Graz as an artwork in a public space. In a mixed-methods approach, we asked passers-by and interviewed experts on Graz as a smart city and on the Arthouse's role concerning the image of Graz as a smart city. The research found strong hints that indeed digital artworks with large screens or media façades at public spaces are parts of a city's weak location factors as well as of the city's urban structure and may symbolize the city's smartness. A practical implication of this finding is that artists, computer and information scientists, city planners, and architects should include interactive contemporary digital art into city spaces in order to demonstrate the city's way towards knowledge society.

유비쿼터스 사회가 도래함에 따라 유비쿼터스 기술을 도시에 적용한 u-City가 개발되고 있다. u-City는 다양한 정보화 기기들이 존재하며 정보화 기기 사이를 연결하는 다양한 네트워크 기술이 상존한다. u-City의 핵심 요소인 uMC(ubiquitous Management Center)는 u-City 내의 모든 서비스를 처리하도록 설계되었으며 도시를 통제하는 중요한 기능을 수행한다. 따라서 사용자의 인증 및 보안을 처리하기 위한 기술이 요구되며 이러한 기술은 uMC에 필수적으로 구현되어야 한다. 본 논문에서는 기존의 인증 기술에 대해 설명하고, u-City 네트워크 환경에 적합한 인증 방법과 절차를 제안한다. 제안된 u-City 통합 인증 시스템은 u-City에 존재하는 정보화 단말기와 사용자를 인증하여 정당한 사용자에게만 IP를 할당하고, 할당된 사용자에 대해 정책에 따라 차별화된 권한을 부여 할 수 있으며, 따라서 uMC의 보안에 중요한 역할을 한다.

The purpose of this study is to develop Web database for healthy city that contains healthy city indicators for making city health plans, setting project priorities, monitoring projects, and evaluating healthy city projects, effectively. Using Delphi survey method for identifying indicator domains and indicators, we extracted nine domains with thirty-four healthy city indicators. Based on the appraisals of DB users about the contents of DB, a web database for healthy city Wonju was constructed. We developed a web database system for the purposes of sharing high quality health related data for managing and evaluating healthy city projects. The web database currently provides variety data in the web address, http://healthycity.wonju.go.kr/index.html. The web DB comprised with major healthy city indicators that are the most important indicators, healthy city indicator data that have a variety data set for encompassing all domain areas such as city infrastructure, health medicine, economies, and all other related areas and qualitative data that contains policy reports, research results, healthy city information and all other tips. A database of healthy city is very essential and important because it makes healthy city projects alive by managing and sharing healthy city related data effectively. But we need to fill out some blank cells in DB because there are currently unavailable data for some indicators. In conclusion, we expect the web DB contributes information sharing of healthy city project teams and improving healthy city project quality at Wonju city in Korea.
