IT를 매개로 서로 다른 분야의 기술들이 상호 융합되어 새로운 서비스 또는 기술을 제공하는 유비쿼터스 패러다임은 도시에 대한 새로운 시각을 제공하고 있다. u-City는 첨단 정보통신 인프라와 유비쿼터스 정보서비스를 도시공간에 융합하여 도시생활의 편의 증대와 삶의 질 향상, 체계적 도시관리에 의한 안전보장과 시민복지 향상, 신산업 창출 등 도시의 제반기능을 혁신시킬 수 있는 차세대 정보화 도시를 의미한다. 성공적인 u-City 건설을 위해서 기존의 지자체GIS 개념을 확대한 지능형 도시공간정보의 개념이 필요하며, 지능형 도시공간정보를 효율적으로 제공하기 위한 서비스가 요구된다. 이러한 지능형 도시공간정보 서비스는 도시 전반의 영역에서 제시될 수 있으므로 다양한 서비스를 도출할 수 있다. 이에 본 연구에서는 지능형 도시공간정보의 개념을 살펴보고, 기존 u-City 관련 서비스 분류에 관한 선행 연구내용을 중심으로 지능형 도시공간정보 서비스 분류체계를 제시였다.

With the advent of u-City(ubiquitous city) concept, the importance of urban management has been increased. GIS is a foundation for the efficient urban management and an essential technology for the development of u-City. u-City, which aims for convenient, safe, healthy, and comfortable life, provides diverse services based on advanced information technologies, and it will offer more services in the future. u-City integrated management platform enables the ease of service development, guarantees the quality of services for the resident, and provides organic information sharing. Moreover, the platform by integrating GIS and other common management functions, makes possible efficient urban management. In this paper, required functions of u-City integrated management platform for u-City service were analyzed. As a result, GIS module for management of street lights and supervision of fire was developed and the application usability of u-City integrated management platform was verified by service simulation.

As the title signifies, the current study aims at the realization of u-City, which is short for the Ubiquitous City. For this purpose, firstly, the meaning of u-City realization is sought in the study based on future urban changes. Along with this, current issues in the course of u-City realization are gathered based on in-depth interviews with relevant experts. Thirdly, necessary for the comprehensive planning and management of u-City, several strategies are presented by classifying it into u-Infra and u-Service, and considering relevant laws and regulations. And the study divided the execution process into project, development and management levels, and then suggests some realization strategies that are level-dependent.

유비쿼터스도시서비스에서의 가장 핵심적인 기술을 유비쿼터스도시서비스를 제공하기 위하여 설치된 도시기반시설물과 도시기반시설물로터 정보를 수집하고, 시설물을 관리하기 위하여 설치된 센서이다. 시설물에 설치된 센서는 USN으로 연결되어서 도시통합운영센서와 통신을 하여 센서로부터 수집된 정보를 전송한다. 도시통합운영센터에서는 USN을 통해서 센서 또는 시설물을 제어한다. 이러한 USN에는 Zigbee, 6LoWPAN등 센서의 특징에 따른 프로토콜이 있고, 유선네트워크, 무선네트워크 등을 통해서 USN의 네트워크를 구성한다. 본 논문에서는 유비쿼터스도시의 시설물 관리를 위해서 사용되어지는 센서 및 USN의 특성을 분석하고, 센서 및 USN의 다양성에서 발생하는 문제점을 분석하고 이를 해결하기 위한 방안을 제시하고자 한다.

Recently, a lot of local autonomous entities are promoting Ubiquitous City(U-City) Construction by integrating Information Communication Technology(ICT) with city development, and also internationally, a lot of cities are making efforts to develop U-City to intensify a city's competitive strength and improve life quality of city dwellers. In keeping with such a stream of the times, each local autonomous entity and project developer are developing a lot of methodologies to establish optimal U-City in corresponding cities and also inquiring into a variety of development procedures, such as connecting existing urban development methods with information establishment methods. The method used usually is to establish Information strategy Plan(ISP) for a city which will be developed through consulting in the stage of city development planning. ISP is to establish vision & strategy for building the ubiquitous city and is a methodology including city vision, strategy, goal, and implementation method, etc. However, due to a lot of variables, such as a variety of city environment, establishment period, budget, information technology, and etc., it is difficult to contain establishment plans for every occasion in a similar method, in reality. Therefore, it is naturally necessary to suggest plans for city vision & strategy, and selection of element technology/service. Thus, this paper suggests models for vision & strategy establishment of U-City and suggests Top-Down Approach and Bottom-Up Approach method as a plan for U-City establishment. In addition, this paper analyzes general promotion methodologies for constructing U-City and analyzes how these two strategic methods [Top-Down Approach and Bottom-Up Approach] for city vision establishment are composed in such a methodology, to define and analyze its constituent plan.

Recently, the concern of ubiquitous City(u-City) in each level of governments is on the increase, and they are professing themselves to follow the u-city concept on constructing new urban development or urban renewal project. But the u-city plan and construction proceed as the simple sets of advanced technology without fundamental space concept or space plan of the u-city. Therefore, the u-city as a citizen's living space and a basic urban environment is defined in this article, the viewpoint of the space plan and the recent trends of u-city in korea are reviewed. On the basis of this review, this article proposed an approach of the spatial plan for a u-city construction, here the approach consisted of the 3 stages of planning, constructing, and maintaining of the u-city, and finally the role of the participant in the each stage and spatial hierarchy was proposed.

최근 건설되어지는 도시들은 정부의 신도시 정책의 일환인 첨단 도시 건설을 목적으로 하는 Ubiquitous City를 계획하고 있다. Ubiquitous City는 언제 어디서나 유비쿼터스 서비스와 인프라가 제공되는 환경을 가지고 있으므로 노출 위험이 높다. 보안을 고려한 개별 시스템들의 설계는 정부 정책과 함께 활발히 진행되지만 통합 시스템을 관리하는 면에서의 방안은 제시되지 못하고 있다. 보안관리방안이 성립되지 못한다면 침해 유형이 고도화되면서 항상 변화하는 유비쿼터스 시대에 보안은 취약해질 수밖에 없다. 시스템을 총괄 관리 및 관제하는 통합네트워크전산센터인 U-City전산센터의 보안 관리망을 구성하고 취약한 시스템들의 보안을 관리하는 대책이 필요하다. 본 논문에서는 유비쿼터스 보안망의 체계적인 관리 방안을 통합보안관리(ESM)를 중심으로 기술적인 보안관리대책을 제안한다. 제안된 보안관리대책이 Ubiquitous City를 계획하는 모든 신도시들의 플랫폼이 되도록 한다.

The international society under the internet technology have been declining boundaries of the global economy. After this step, a social revolution will be happen from the ubiquitous technology which fives objects intelligence to serve people. And then it is expected that every part of a city competitive power is defined by both in qualify and in quantify of the ubiquitous information unit in the future. On this score, now each nation is trying to set relative services and broadband networks to lead the ubiquitous industry. Therefore this paper analyzed about the progress and prospect of a local U-city plan in our nation Especially we propose a new city development model which use U-city and self-communication network to Improve a city competitive power.

The international society under the internet technology have been declining boundaries of the global economy. After this step, a social revolution will be happen from the ubiquitous technology which gives objects intelligence to serve people. And then it is expected that every part of a city competitive power is defined by both in quality and in quantity of the ubiquitous information unit in the future. On this score, now each nation is trying to set relative services and broadband networks to lead the ubiquitous industry. Therefore this paper analyzed about the progress and prospect of a local U-city plan in our nation. And than we propose a method of configurating broadband self-communication network on the base of cost and utilization Especially we propose a new city development model which use U-city and self-communication network to improve a city competitive power.
