  • Ubiquitous City is emerging as a new paradigm in future city development. U-City is nationwide project for future strategy to implement sustainable city environment and solve several issues in urban area. And as worldwide leading role on future city research, there are lots of U-City related researches in Government and Industry sector. However, it has raised unsustainable development concerns that indiscriminate promotion and visibility for long-term effects because it is not conducted an assessment. Thus, to overcome these problems and in order to develop a more stable U-City project, need to a fundamental consideration about U-City evaluation. This study is to provide the evaluation framework for Ubiquitous City(U-City). The framework is consisted of evaluation dimensions derived from characteristics of U-City development project. From this research, we expect it helps U-City development to be inspected and managed.

  • 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.

  • 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.

  • '08.3월 U-City법이 제정되었고, '09년에 U-City법에 근거한 제1차 유비쿼터스도시종합계획 (이하 U-City종합계획)이 수립되었다. 이후 계획에 따라 U-City R&D, U-City시범도시 지원사업 등이 추진되었으며, 기술, 서비스, 인력양성, 산업지원, 법제도 개선 등 다양한 부문에 U-City 지원 정책이 시행되었다. 이로 인해 국내 U-City 사업이 활발히 추진되었으나 주로 공공 주도의 신도시를 중심으로 구축되어 과도한 건설비용 및 관리운영비 부담, 중복투자 등의 다양한 문제를 발생하게 된다. 결국 신도시 조성 개발이익을 통한 U-City 구축은 건설경기의 침체와 함께 심각한 위기를 맞게 된다. 하지만 새정부 출범 이후 U-City는 창조경제 대표사업으로 채택되어 재도약할 수 있는 계기가 마련되었고 정부는 지역경제 활성화의 일환으로 도시재생사업에 U-City를 접목하는 등 U-City 부흥을 위한 시도를 지속적으로 하고 있다. 특히 신도시 개발로 치우쳐서 발생된 기존도시와의 불균형을 해소하기 위해 다각도로 해결방안을 모색하고 있다. 이에 현 시점에서는 기존도시에 초점을 맞추어 U-City 방향을 살펴보는 연구가 필요하며, 기존 신도시형 U-City가 추구했던 정보통신 위주의 계획에서 벗어나 지역특성 및 수준 등을 고려한 도시계획적 측면으로 접근하는 것이 바람직하다. 본고에서는 국내외 스마트시티 동향을 파악하고 우리나라의 신도시개발형 U-City 구축 현황의 문제점을 진단하여 기존도시형 U-City 구축의 필요성을 도출하였다. 이를 토대로 실효성 있는 기존도시 U-City 구현을 위하여 도시계획적 관점에서의 고도화 방안을 모색하고자 한다.

  • Recently, a lot of local autonomous entities are promoting Ubiquitous City(U-City) Construction by integrating Information Communication Technology(ICT) with city development, and also internationally, a lot of cities are making efforts to develop U-City to intensify a city's competitive strength and improve life quality of city dwellers. In keeping with such a stream of the times, each local autonomous entity and project developer are developing a lot of methodologies to establish optimal U-City in corresponding cities and also inquiring into a variety of development procedures, such as connecting existing urban development methods with information establishment methods. The method used usually is to establish Information strategy Plan(ISP) for a city which will be developed through consulting in the stage of city development planning. ISP is to establish vision & strategy for building the ubiquitous city and is a methodology including city vision, strategy, goal, and implementation method, etc. However, due to a lot of variables, such as a variety of city environment, establishment period, budget, information technology, and etc., it is difficult to contain establishment plans for every occasion in a similar method, in reality. Therefore, it is naturally necessary to suggest plans for city vision & strategy, and selection of element technology/service. Thus, this paper suggests models for vision & strategy establishment of U-City and suggests Top-Down Approach and Bottom-Up Approach method as a plan for U-City establishment. In addition, this paper analyzes general promotion methodologies for constructing U-City and analyzes how these two strategic methods [Top-Down Approach and Bottom-Up Approach] for city vision establishment are composed in such a methodology, to define and analyze its constituent plan.

  • 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.

  • 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.
