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.

This study proposed a traffic responsive urban traffic control system using RFID(Radio Frequency Identification) technology to get traffic information. The proposed system is a decentralized control using model predictive control. The objective of proposed system is to get traffic data using advanced technology for controlling the junctions' traffic rights. A simulation example is provided to demonstrate the applicability of the proposed model.

This paper proposes a standard method for linking data between the U-City Integrated Urban Management Platform and u-service systems through systemization of event identification and standardization of event priority. By applying the proposed method, the incoming events to the Management Platform are listed and processed according to their priority of urgency. The application of the systemized event ID and standardized event priority enables prompt counter-measures against urban emergencies and disasters, which improves the efficiency of business processes by reducing the time and cost to complete required actions.

The u-City offers diverse u-services, which are integrated with information and GIS technologies, by utilizing an integrated management platform for controlling the city efficiently, increasing convenience of city lift, and improving the quality of lives. An urban control system is a core element of the u-City to connect organically and expand all kinds of information through various u-interfaces. This study presents the implementation of a GIS service module based on the urban control system for the efficient development of u-services, which contributed to the successful execution of GIS service scenarios that include processes of unexpected events, air pollution monitoring, and emergences. The results of the study can be used as basic data for the design and operation of practical u-City services.

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.

최근 들어 도시 집중화 현상 및 기반산업의 불균형적인 발전에 따른 문제를 해결하기 위해 유비쿼터스 기술 기반의 혁신도시 개념인 u-City에 대한 연구와 발전의 필요성이 대두되고 있다. 이에 본고에서는 u-City의 개요와 필요성, 그리고 기존도시와의 개념적, 기술적 차별성에 대해 분석하고 이와 관련된 요소기술들에 대하여 분석한다. 그리고 이를 바탕으로 u-City 구축 시 필요한 다양한 서비스에 대하여 분류하고, 각각의 분류에 따른 실제 서비스 적용 사례에 대하여 분석한다. 또한 이러한 u-City에서의 다양한 서비스들에서 발생 가능한 보안 문제점에 대하여 분석하고, 이를 효과적으로 해결하기 위한 보안 고려사항들에 대해 분석한다.

유비쿼터스 기술의 보급으로 우리 생활에 밀접한 연관이 있는 도시시설 등이 IT기술과 융합되어가고 있다. 이로 인해 개별 네트워크에서 운영되던 각종 IT 서비스들도 u-City 서비스로 융합되고 있다. 하지만, u-City 안에서 새로이 융합되는 신규 IT서비스들이 구축되는 과정에서 보안요소의 고려 및 적용이 미흡할 경우에 u-City 서비스의 안전성 및 신뢰성에 심각한 문제를 야기할 수 있다. 이를 해결하기 위해, 본 논문에서는 u-City 서비스에서 발생 가능한 정보보호 위협을 분석하고 이를 극복하기 위한 정보보호대책 및 정책 과제를 제시하도록 한다.

As the ubiquitous technology has been widespread, the u-service development driven by the private sector is increasing these days. In this paper, a new development methodology of interactive u-services for a mixed-use complex in u-City is proposed. The current state-of-the-art IT, Web2.0, assumes that information must be communicated in both way, not only from service provides to users but also from users to service providers. Here the user-driven u-service will be utilized for service providers to customize user services. By this interactive u-service paradigm, the information users become the information providers so that the mixed-use complex will take advantage of massive information. Also, admitting that the mixed-use complex is limited in terms of the space size, the network effect of information and shared contents created through the interactive u-services can be maximized.
