In recent years, Ubiquitous City (u-City), the integrated and convergence of ubiquitous services, infrastructure, technologies and city management of the new future development city, is being initiated by the Korean government and local authorities as their new national growth engine. However, a performance measurement system for evaluating and monitoring the impacts of U-City implementation is yet to be established. This paper aims to develop an integrated performance management system (PMS) and extensively used as a tool for managing performance activities to support the visions and goals of the u-City operations. Based on current reviews on the literature and interviews with experts drew Critical Success Factors (CSF) and Key Performance Indicators (KPI) by four different measurement domains including U-City services, infrastructure, technologies, management and developed into an integrated performance measurement system based on the Balanced Scored Card (BSC) perspective. The system also provides number of examples of 'u-City Strategy Map' which illustrates a causal relationship between CSFs to execute u-City visions and goals.

최근 수요가 급증되고 있는 u-City의 경우 성공적인 구축을 위하여 도시통합운영센터라는 개념을 도입하여 추진하고 있으며, 나아가 이를 보다 확장시킨 개념인 도시통합운영체계의 중요성이 강조되고 있다. 이처럼 u-City의 핵심기반으로서 도시통합운영체계의 중요성이 증대되고 있는 가운데, 효율적인 도시통합운영체계 구축을 위해선 공간정보 활용이 필요하다. 즉, 지자체에선 오래전부터 GIS 정보화 사업을 추진하고 있으며, 공간정보를 구축 활용하고 있다. 효율적인 도시통합운영체계 구축을 위해선 공간정보의 활용은 필수적이며, 이는 u-City 추진의 핵심적 기반이 될 것이다. 본 연구에서는 u-City 도시통합운영체계에서 공간정보를 효율적으로 활용을 위해 u-City의 도시통합운영서비스와 관련하여 공간정보의 활용성과 활용방안을 제시하고자 한다.

This Study is U-City based facilities analysis procedures and techniques of the effective management. We analyze the existing procedure of the management of urban based facilities. And U-City based facilities of management procedures were presented. U-City based facilities were classified regular inspection, safety inspection, emergency inspection, accurate safety diagnosis, routine work and emergency work. We analyze the skills required in the management of these facilities. The procedures for the management of U-City based facilities will improve efficiency of urban management and safety of citizen. As a result, the management of U-City based facilities will lead to improving the quality of services for citizens and competitiveness of the city. Furthermore, this will be the foundation of the environment that people can enjoy safe and convenient life.

정부 주도적으로 전국적으로 U-City 구축이 확산되고 있으며 특히 신도시형 U-City 사업은 동탄 U-City가 완공됨에 따라 본격적인 운영단계에 접어들고 있다. 그러나 신도시형 U-City 사업은 이원화된 사업 수행 체계로 인한 많은 문제점들이 드러나고 있다. 본 논문에서는 U-City 사업의 가치사슬을 분석하여 문제점을 도출하고 이에 대한 해결방안으로서 U-City 거버넌스 모델을 제시하고 있다. U-City 거버넌스 모델은 구축뿐만 아니라 운영 단계까지 포함한 U-City 라이프사이클을 효율적이며 효과적으로 관리할 수 있는 조직 체계를 정의한다. 이와 같은 U-City 거버넌스 모델은 국내 U-City 사업뿐만 아니라 도시수출의 성과를 극대화 할 수 있는 기반을 제공할 것으로 기대된다.

As adopting ubiquitous technology into civil engineering, new city model is suggested called U-City. This paper proposes the framework of U-City management center to support effective services operation. The aims of the framework are to provide the development and operation environment for U-City services. Basically, these objectives are achieved by adopting the semantic web service technology to the framework. In this paper, OWL-S is mainly conducted to represent the description of U-City services. In addition, this paper insists that fine grained unit services are required to guarantee reusability, compatibility, and scalability of the services on U-City management center. The documentations conducted by OWL-S are provided as an example of service descriptions. At the last section, this paper also presents the architecture of U-City management center which enables automatic service discovery, selection, composition and interoperation.

In this paper, the requirements for information security are presented in the ubiquitous ecological(u-Eco) city. The various definition of ubiquitous city is analyzed first, the concept of the u-Eco City, services and major projects are then presented. The framework of the integrated operating center for u-Eco city is proposed, the privacy, data security and network facility protection in the center are analyzed. Unlike to previously proposed security algorithms, the light-weight encoding algorithms(such as block/stream encoding, pseudo-random generator, hash function, and public key encoding) in the u-Eco city center are required to communicate the information in the ubiquitous sensor network. Furthermore, the principal policies guaranteeing the secrecy and authentication for the private information are also presented.

도심내 지속적인 차량증가에 따라 도시의 주차문제는 운전자에게 있어 과거부터 현재까지 여전히 불편함을 주고 있다. 이에 유비쿼터스 기술을 이용한 주차시스템이 활발히 연구중이며, 센서를 이용한 새로운 형태의 주차장이 생겨나고 있다. 따라서, 본 논문에서는 국내 사례 및 선행연구의 검토를 통해 시사점을 도출하였고, 더욱 더 발전된 모바일을 기반으로 한 유비쿼터스 기술을 적극 활용하여 능동적이고 개인 맞춤형의 통합 주차서비스가 가능한 지능형 u-Parking시스템을 제안하였으며, 개별 운영관리의 비효율성을 u-City의 통합운영센터와의 연계를 통하여 효율적 방법을 제시하였다. 또한 주차장 스마트 검색, 인터넷 주차장 예약제, 경로연계 맞춤형 정보제공 등 u-서비스 비즈니스 모델 제시를 통하여 효율성과 경제성을 확보방안을 마련하였다.

It is a fact that we are yet to recognize and sense the U-City even though the business of U-City construction has been started many years ago. One of the causes is that UCity was thoughtlessly developed in the industry-centered environment for a tangible achievement, despite of need on more systematic development and organized management. Fortunately, it is expected that the most part of the situation will be solved, since "laws on the construction of the ubiquitous city" for planning, construction and management has been promulgated on March, and U-City project will be systematically promoted by the related laws from now. Therefore, intention of this study is the sustainable development of the U-City by analyzing the previous process and problems of the U-City Construction project of local governments and reengineering U-City construction project process in accordance with new laws, using the BPR methodology.

SOA (Service-Oriented Architecture), which has become very popular recently, is a new paradigm for software development and application. In this paper, we propose an integrated architecture which is able to effectively manage and control a variety of services for U-City projects focusing on the importance of service integration. SOA has a number of important features such as loose coupling, standard bases, and distributed computing, all of which are the essential elements for merging and providing various services in U-City projects. We exploit the ESB (Enterprise Service Bus) for reflecting those features, which is a core module linking mutually heterogeneous components so that the communication of services can be implemented. In this paper, we discuss the necessity of SOA in U-City services and a possible scenario and method for the implementation. Finally, we propose an integrated architecture for the U-City Integration and Management Center.
