현 정부는 신성장동력의 녹색기술산업 분야에서 첨단그린도시를 선정하여, 향후 많은 지자체 등에서 앞다투어 U-City 건설을 목표로 많은 서비스를 도입할 것으로 예상된다. 그러나, U-City 서비스, 프로세스, 필요한 H/W 등에 대한 표준화는 이루어져 있지 않은 상황이다. 이에 본 연구에서는 U-City 건설에 활용될 수 있는 IT 기반의 U-City 서비스 개발 방법론을 제안하고자 한다. 이를 위해 본 연구에서는 U-City와 NSD(New Service Development) 방법론들에 대한 문헌연구를 중심으로 U-City Service 개발 방법론 도출을 위한 분석을 하였다. 이러한 U-City 서비스 개발 방법론 연구결과를 통하여 U-City 서비스 도입을 위한 지침서를 제공할 수 있는 토대를 마련할 것이다.

u-City사업은 완성까지 5년 이상이 소요되는 대형 장기사업으로, 정보시스템 개발 및 정보통신공사가 동시에 이루어지는 복합공종 사업이다. 이러한 대규모 사업을 차질없이 수행하기 위해 u-City사업에는 감리도 동시에 수행된다. 그러나 u-City감리는 아직 단일화된 감리기준이 없어 정보시스템 감리기준 및 정보통신공사감리 업무수행지침이 각각 적용되고 있으며, 이로 인해 감리 현장에서는 통일된 일정계획 수립이 어렵고, 업무 분장이 불명확하여 감리대상 일부가 누락되는 경우도 발생한다. 본 논문에서는 정보시스템 감리기준 및 정보통신공사감리 업무수행지침으로 이원화된 감리기준으로 인해 발생되는 문제점들을 살펴보고 이의 개선방향을 제시하였다.

This study ultimately aims to suggest directions for development of U-City Competitiveness Index through thorough analyses of U-City competitiveness concepts and previous research in U-City-related index. In an attempt to reach the aforementioned goals, the concept of U-City competitiveness is presented based on existing publications on informatization age, future city, and U-City. Next, insights on the development of U-City Competitiveness Index are provided via analysis of research on indices regarding U-City and future city. Finally, the process of developing UCity Competitiveness Index and cautionary comments for each developmental step has been provided. Based on the research results, U-City competitiveness refers to the ability to respond to demands of residents in a timely manner as well as to manage U-City, ICT, U-City infrastructure, and U-City services that maximizes the efficiency of urban space management. In order for proper assessment of these criteria, development of assessment tools, selection of indices, standardization, allocation of weight per index, and construction of assessment framework are required.

A law and enforcement ordinance related to "ubiquitous city" (U-city) has been announced officially in Korea and practical standardization which is connected with U-city is in progress. The U-city defines citywide service over a city providing its infrastructure. The key facilities of U-city include intelligent equipments, networks, and operational facilities. Especially, the main focus of them is the intelligent equipments that are defined as facilities being applied to information technology. However, U-city has not been provided with standards related to actual construction of intelligent equipments so far. In this article, we survey standards for intelligent equipments for existing infrastructure and U-city's services.

This study demonstrates a basic concept and designing direction for the realisation of disaster prevention planning in u-City(u-BangjaeCity) that is from establishing a planning system in terms of the areas of professional disaster and safety management for the national disaster management. and designing disaster or safety management system via using ubiquitous technology for the scientific disaster management. In order to realise u-City it is necessary to maps out interrelation amongst various services such as traffic, environment and disaster prevention. Domestic and international case studies regarding the tendency of disaster prevention planing in u-City and its analysis could be the fundamental resource in order to develop the standard model of u-BangjaeCity.

This paper aims to study the effects of quality of u-City public service on customer satisfaction in the Korea and is summarized as follows. First, we propose a model for assessing customer's satisfaction on u-City public services. The model comprises of information system (IS) quality, information quality, service quality and publicity. For verifying a model, a statistical study by SPSS 12.0 and AMOS 16.0 has been performed. Second, it is shown from the analysis that information system (IS) quality, information quality and publicity have a positive effect on customer satisfaction. while service quality does not. Last, the study shows that u-City public service enables any citizen to connect to necessary service in anytime and anywhere.

This paper presents the main business models in ubiquitous city (u-City), the future city strategically integrated with the ubiquitous computing technology. Based on the concept of u-City, the chief services related to the u-City that has been actively developed are analysed, and then the best main four business models (u-Tour, u-ITS, u-SCM and B2B) for SongTan city are presented. The four business models are selected from making an analysis for the present situation of the tour industries, industrial complex, traditional market in SongTan. With the business models, the strategies to realize the active business transactions, high revenues, high value-adding industries, self-sufficient business through the construction of u-City are also presented. Finally, the promoting plans for local autonomy party, citizen party and consortium of industries/universities/researches to give an comfortable u-Life to citizen in SongTan are described.

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.

Though the interest for the construction of ubiquitous city (u-City) has been increased in many researches, many of those efforts are still done somewhat separated ways such as from the perspective of architectural design of urban city or from the perspective of underlying ICT (Information and Communication Technology) implementation. Since there are various services and technical components involved in u-City implementation, those separated approaches can cause much troubles while implementing u-City. In addition to this, because u-City components are continually changing and expanding, to cope with this evolution, many researches about the infrastructure of u-City should be done in a systematic way while integrally considering various perspectives of u-City. In this research, by combining WBEM/CIM standards to GMA (Grid Monitoring Architecture), we could provide WBEM/CIM design that is usable for u-City implementation. In contrast to the conventional research that is still abstract, our study presents concrete and implementable u-City infrastructure model. We hope our result will be a valuable reference for the other u-City infrastructure-related researches.

U-Services(Ubiquitous Services)는 최근 성공적인 U-City의 구축에 있어서 핵심적인 요소로 주 목 받고 있다. U-City라는 개념은 현재 한 도시의 통신과 인프라의 통합 관리라는 차원에서 주로 접근되고 있는 실정이나, 궁극적으로는 한 도시의 사용자들인 시민들에게 어떠한 가치를 돌려주고, 이를 어떻게 지속 할 수 있을지에 대한 의문이 지속적으로 제기되고 있다. 도시의 사용자인 시민과 입주기관들에게 어떠한 '가치'를 제공할 수 있는지에 대하여 고민하는 과정으로써, 본 연구 에서는 소요 기술, 활용 인터페이스, 구현되는 공간, 그리고 제공하는 컨텐츠에 따라 정의할 수 있는 방법론을 제시한다. 또한, 제조업에서 주로 활용되던 QFD(Quality Function Deployment - 하나의 제품을 개발하는 과정에서 요구되는 기능이나 속성을 규정하기 위한 Analytic Hierarchy Process framework)를 도시 설계로 적용하여 SVD (Service-Value Deployment method)라는 방법론으로 제시하고 있다.
