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.

The purpose of this study is to define U-Eco City services and to analyze the possibility and easiness of application in urban space. The most significant meaning of this study is that these results could be used as the design and planning guidelines for integrated U-Eco City. This study progress as follows; First, U-Eco City concept and their services were defined and the spatial units of U-Eco City were distinguished through literature review. Second, U-Eco City spaces are classified into four levels such as building, street, facility and district. Finally, the application of U-Eco city services was analyzed together by the statistical technique of cross-tabulation. 35.7% of U-city services was serviced in urban district and 38.8% of Eco City services was applied to Building. U-City and/or Eco city services were adapted differently according to the urban spatial hierarchy. Those services should be applied in terms of the characteristics of urban space in designing and planning U-Eco City.

U-Services, which are offered from local governments based on their Ubiquitous City Plans, are only focused on facility and urban management services. Also Citizen oriented U-service is only planned. This study's purpose is to propose the implication for provide of the Citizen oriented U-service comparing with U-Service plan of 'Ubiquitous City Comprehensive Plan' and 'Ubiquitous City Plan' through a network text analysis and word frequency analysis. It was calculated a important keyword that was extracted the service plan contents of the 'Ubiquitous City Comprehensive Plan' and 'Ubiquitous City Plan' of the four local governments. The network text analysis and keyword frequency analysis was performed through derived keyword. Based on the analysis results, awareness of the citizens can be expected to increase about U-City by activating a excavation of Citizen oriented U-service in a variety of sector through additional services and policy of financial support in the next Ubiquitous City Comprehensive Plan.

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.

본 연구에서는 u-City인력수급 전망을 토대로 국토해양부의 u-City 관련 인력양성에 대한 실천계획이 효율적으로 실행될 수 있는 방안을 제시하였다. u-City를 추진하는 지자체, 개발사업자마다 공통적으로 제기하는 문제점은 u-City 관련 고급 및 기능 인력의 절대적인 부족이다. 그러나 u-City 전문인력은 u-City건설의 특성상 도시계획 개발, 정보통신망, IT 등 다양한 분야에 대한 전문지식을 갖추어야하나 이러한 고급인력이 배출되고 있지 않다. 따라서 본 연구에서는 인력양성방안의 목표를 'u-City의 성공적인 추진에 부합하는 전문인력양성'으로 설정하였으며, 수요자 중심의 교육, 지역 균형적인 전문인력양성, u-City 관련 분야의 융 복합교육, u-City 관련 교육인프라 구축을 추진전략으로 수립하였다. u-City 인력양성의 추진목표 및 전략을 실행하기 위한 중점추진과제로는 'u-City건설 전문인력교육 관련 수요전망', '지역별 거점대학 선정을 통한 전문인력의 양성', 'u-City 인력양성센터 건립추진', '교육포탈을 통한 온라인 교육', '교육인프라 구축' 등 5개를 선정하였다. u-City 인력양성을 위한 추진전략의 성공적 실행을 위해서는 중점 추진과제들간의 유기적인 연계가 필수적이다.

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.

Ubiquitous City(U-City) in Korea is not a fantastic wonderland but an on-going real phenomenon. Many researchers so far have mainly dealt with a rosy future where U-City would potentially promise the high Quality of Life and positive economic effects. However, a suspicion of unexpected disadvantages can be able to take place in the bright future of U-City : the running cost of U-City. Without full consideration of it, descendants living in the U-City in near future will suffer from the heavy burden in operating the U-City. Given this circumstantial background, the aim of this study is to indicate potential solutions to address a sustainable U-City controlled by the virtuous cycled mechanism toward a self-sufficient city, which will illuminate a new paradigm of the city history. Solutions were sought from the several viewpoints, which were behavioral and institutional aspects, developing profitable business models and core technologies applicable to U-City, and building self-owned networks. Based on this preliminary study, further efforts and devotion to seeking virtuous-cycled U-City model will contribute to bringing a prominent future of U-City whose belongings will be able to manage to enjoy better quality of life.

The realization of u-City is coming near in some local governments by applying various city services, namely, u-City services to the city construction field to improve competitiveness of the city. But it is a reality that some local governments are experiencing many trial and errors in application of the u-City service in addition to the problem posing that the u-City service is not considering characteristics of development or application environment of an individual city. The present research proposes a service model for on-site application of the u-City service to solve this problem. The proposed model suggests a method for specifically conceptualizing and objectifying the on-site application that the existing concept-oriented model or an architecture-oriented model, etc. didn't provide. The verification system on effectiveness or effects of the u-City service model to remove ambiguity on the u-City service especially. The verification system of the u-City service model grasps the technology, function, procedure and target, etc. that the u-City service contains, evaluates whether the model satisfies conditions that the model should have, and secures objectivity and predictability of the u-City service model through confirmation on propriety, implementation and effectiveness, etc.
