The purpose of this study is to suggest development directions and elicit future research themes of U-City and future city by identifying the research trends of U-City theses. For this, meta-keywords were elicited based on the theses of U-City and future city published from mid 1990s to 2010. Centered on the meta-keywords, temporal keyword analysis was performed to compare the research trends of U-City and future city theses in Korea and oversea. The results show that most of U-City and future theses in Korea and oversea mainly dealt with technology. U-City theses in Korea have a tendency to research technology, methodology, service, planning and management in order from the early beginning. However, the U-City and future theses in oversea have a tendency to continuously study U-City applications to city through the model based on the technology and methodology. Therefore, the U-City research in Korea should focus on aspects of urban regeneration, urban scale, and so on. That is to say, the research in near future is required to apply the U-City to various urban themes.

Last February, $\ulcorner$The Act on Ubiquitous City Construction and etc.$\lrcorner$ was approved by the National Assembly. The law stipulates the regulations on the planning, construction and management of the Ubiquitous City. As its national-level law system is about to take its effects, future new city developments are expected to have its legal basis to be built to meet ubiquitous city requirements. Also, it is anticipated that such needs would require much more planning techniques and strategies. In reaction to those upcoming needs, this study is to search for new planning approaches to realize the u-City in reality. It is also to supply with the framework to execute the u-City projects in more structuralize and systemize manner. Therefore, with the purpose of the establishment of comprehensive planning system, the theoretical bases were sought in relation to planning u-City, pre-existing u-City development cases and regarding regulations were analyzed, and then basic concepts, features, and constituent factors were set up.

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.

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.

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.

We proposed the concatenation of logistics' Information to constructing the intelligent logistics city that is to manage efficiently cargo distribution as providing at real-time information of cargo location trace and management through the Telematics/RFID. Case of the Incheon of the "Air Logistics Hub", this area is on an increasing trend on the quantity of cargo transport of the Air & Sea cargo system until 2006. As intelligent project of the Air's and the Sea's field is independently developed at each area, it is a problem on the concatenation of logistics' information such as freight location trace and management, operation management and route information of cargo vehicles. Therefore, we propose the advanced transport service model for the concatenating smoothly of Air & Sea cargo system. In this paper, we only manage the model of Air & Sea cargo system of the advance logistics city.

인터넷의 발달로 인해 현대의 사회와 도시는 인터넷 이전의 사회와는 확연히 다른 모습으로 변화하게 되었다. 이러한 사회적 배경을 바탕으로 세계의 여러 나라와 도시들은 기존의 도시 기능으로는 타 국가와 도시에 대한 경쟁우위를 가지기 힘들어졌다. 이러한 시대의 요구를 충족 시켜줄 수 있는 것이 바로 u-City의 출현이다. 각국과 도시들은 여러 사업체와의 제휴를 통하여 활성화된 투자환경을 조성하고 특화된 사업 모델을 통해 차별화된 서비스를 제공하고, 좁게는 도시민의 편의와 삶의 질을 향상 시키고 더 나아가 지역산업활성화를 도모하여 경쟁력을 높이는데 많은 노력을 하고 있다. 이연구의 목적은 이러한 지능기반 사회를 추구하는 u-City의 발전이 무조건 사회에 장점만을 반영할 것인가와 u-City와 기존도시와의 정보통합관리 및 정보와 조직의 연계방안에 대한 발전방안 살펴보고 어떤 방향으로 이루어져야 하는지 생각해보는 것이 본연구의 목적이다.

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.

IT technologies applied in the urban places are being promoted in each area. Especially infrastructure is performed in the central role of technical support in urban area. However, u-City infrastructure has lack of integrated way and concentrated on only feasible technology which cause frequent substitution and the nested technology in urban area. Therefore this study sheds light on infrastructure through a overall considerations of urban compositional elements and interactions, and apply technology in the process of the industrial era, the domestic supply of urban infrastructure and the cycle comparison-analysis deal with the domestic implications when applied. The results of the study, first, the u-City infrastructure should be supplied by public. Second, u-City infrastructure is in need of the agile character, and standardization of the subtleties is needed. Third, a new system of integrated-macroscopic perspective should be established by changes that influenced by convergences of IT technologies and infrastructures. Fourth, u-City infrastructures planning should consider interactions of services, devices and systems.

Up to the present point in time, the level diagnosis system for urban reactivation have utilized various methods for establishment and management in Korea and overseas, such as city competitiveness evaluation, urban decay diagnosis, etc. However, contrary to performing diagnosis and evaluations on general cities in existing studies, it is found to be a very complex and difficult task to perform a diagnosis on the level of U-City due to its unique characteristics. It is difficult to determine the level of a U-City using a level diagnosis system used for general cities because a U-City is comprised of a connection/fusion of various structural elements. Therefore, in order to perform a systematic diagnosis of a U-City, it is necessary to primarily observe the structural characteristics of a U-city to derive a diagnosis system based on the relativity between each structural element. This study aims to propose a directivity of a U-City level diagnosis system in comprehensive consideration of various elements, such as the objective of a U-City, as well as the structural elements that compose a U-City based on the definitions prescribed in U-City legislations, including ubiquitous city planning, ubiquitous city infrastructure, ubiquitous city technology, services, etc. The results of this study are expected to provide a resolution for the regional quality differences of U-Cities, and also establish a stepping-stone for the realization of U-Cities with high degree of completion.
