U-City는 도시에 IT를 접목하여 도시의 운영과 관리를 효율화하고 다양한 서비스의 도입을 통해 주민들의 복지 향상을 목적으로 하는 신개념의 도시이다. UMC(U-City Management Center)는 U-City의 핵심요소로 U-City의 각종 서비스의 관리 운영을 통제하고, 새로운 부가가치를 생성하는 역할을 한다. 하지만 정보화 사업을 타당성 분석없이 진행하는 경우 전반적인 재정의 운영이라는 정책적인 측면에서 문제가 발생할 소지가 크다. 따라서 UMC 타당성 분석이 선행되어야 한다. 본 논문에서는 정보화사업의 타당성 분석을 위한 선행연구들을 분석하고, UMC의 타당성 분석을 위하여 AHP 모델을 적용하였다. 또한 도출된 모델을 이용하여 구축중인 UMC의 타당성을 분석하였으며, 분석 결과 기술적 타당성, 경제적 타당성, 정책적 타당성 중 기술적 타당성이 가장 낮은 것으로 평가되어 향후 기술적 문제를 보완해야함을 도출하였다.

Even after many constructions of test-beds to verify R&D results, there is no standard to set up a consistent and systematic test-bed master plan. Therefore, this research derives standards of a u-city test-bed master plan. To verify these standards, the research constructs the potential U-City master plan targeting Cheongna district in Incheon. Standards of a test-bed master plan which is suggested by this research will bring strengths to construct a test-bed such as clear construction procedures from presenting directions of planning, saving cost, effective management of equipments, and so on.

u-City 도시통합운영 플랫폼은 u-City 내 교통, 건물, 시설물 등의 첨단화된 기반 시설을 전반적으로 관리하고 체계적으로 통제 가능하도록 한다. 그러나, 도시통합운영 플랫폼에 인가되는 부하는 도시 전반에 분산된 센서와 같은 정보원의 규모뿐 아니라 그 정보의 복잡성에도 의존할 수 밖에 없어, 효율적인 도시운영을 위해서는 플랫폼의 성능확보 방안이 고려되어야 한다. 일반적인 성능개선의 방법으로는 이미 발생한 부하의 효율적 처리를 통한 개선과 더불어 부하원의 근본적 통제와 같은 우회적 방법이 사용될 수 있다. 본 고에서는 네트워크 구조 개선을 통한 부하분산 방법과 더불어 플랫폼의 주 부하원인 센서 네트워크와의 연동방식 개선이라는 두 가지 측면에서 u-City 도시통합운영 플랫폼의 성능개선 방향을 고찰한다.

U-City laws are divided into three categories: intellectual laws, information superhighway laws, and integrated operation center laws. Previous studies have suggested that efficient infrastructure operation and management is necessary in Ubiquitous-City (U-City). However, infrastructure is often interpreted differently by different laws. The purpose of this study was to plan for the integrated operation of intelligent service facilities by comprehensively analyzing the law system of domestic intelligent service facilities and problems in operation and management based on this critical mind. For this, present conditions and problems of intelligent service facilities were found through interviews with people who are in charge of the law system and other practitioners. The necessity of integrated use, including city information generated from intelligent service facilities and installment locations, has been demonstrated. Government ministries and local governments have established various information systems using ICT and U-City laws that specify integrated management and operation, but do not clearly specify definitions for the specific responsibility and authority for main agents participating in facility operation. A system is needed to smoothly mediate the relevant divisions so that they can use installed equipment simultaneously for efficient operation in generating city information. This objective of this study was to prepare a unitary law system for efficient installment and management of intelligent service facilities by establishing a logically linked relationship among the relevant laws and regulations. This will provide a foundation for a management system that has an integrated linkage of intelligent service facilities.

U-Services are inevitably essential for the realization of u-Cities. Most local governments in Korea have expressed much interest in introducing u-Cites and related u-Services. Since researchers anticipate that developing u-Cities will produce economic effects, the Korea government has support local governments to develop u-Cities and necessary u-Services. However, the technology issues have been dominiated in the field of U-City services and most of the U-City services do not reflects all the complicated and pluralistic sides of environment, which are caused by future uncertainties in developing u-Cites. For the purpose of addressing the above uncertainties, this paper attempts to develop the possible scenarios for U-City services through a scenario planning approach. A focus group interview and survey with professionals in the field of planning u-Cities was performed to identify these uncertainties. Then, in order to investigate the validity of the scenario planning methodology, the u-Service "u-Water purity monitoring" is adopted. After considering the relevant issues, we developed two possible scenarios: a mutual linkage service among u-Service related organization and a cooperating and coordinating service among local governments. On the basis of these scenarios, the strategies for potential U-City services are formulated. Various participants in developing U -City services are encouraged to use the scenarios as the foundation of predicting future features of u-Cities and developing the framework of the U-City service scenarios effectively.

In this paper, the design methodology of information security is analyzed to implement the ubiquitous city (u-City). The definition, concept, and main u-services of u-City are presented. The main components, functio ns and offering services of u-City management center are presented, and the laws and network security requirements related to protect the personal information in collecting, processing, and exchanging are also analyzed. Three step security levels of Router/Switch, Firewall/VPN, and IPS are applied where main functions of in terception of abnormal packets($1^{st}$ level), access control for each service($2^{nd}$ level), and real-time network monitoring($3^{rd}$ level) are performed. Finally, application cases are presented to validate the security of personal information in providing the u-City services.

U-city is one of the most competitive field in Korea in the future and it has many subdivision applying field. U-health and u-disaster are important fields of u-city and many projects are being done about those fields. Because each filed is being developed independently, the better efficiency cannot be expected in case of disaster. The most important focus in disaster is the maintenance of human life and dignity, so u-health and u-disaster should be developed together and organized as the same filed for the practical assistance in case of disaster.

The ubiquitous city construction act worked as an institutional basis for the U-City projects which were actively driven in the new urban areas until 2010. However, the country's urban policies which were recently changed focusing on revitalization of the existing towns and urban regeneration led to the increased demand for revision of the u-City law with a strong character of procedural law mainly for the new urban areas. Therefore, this study, taking into account the changes of the country's urban policies and the conditions related to u-City, established the direction of revision on the u-City law as the diversification of the u-City projects, reinforcement of u-City management operation and the supports for the u-City projects, and presented the consequent action plans. This study aims to review the problems with the current u-City law and the improvement plan from the practical point of view for reflecting the country's urban policy flow and demand. It is expected that the result of this study will be able to be utilized as a basic material for supporting the continuous development and expansion of u-City by law and system.
