  • 본 연구에서는 유비쿼터스 도시의 통합운영센터가 가지고 있는 문제점들을 해결할 수 있고, 기존도시와의 IT서비스의 차별성을 위하여 스마트그리드를 운용하는 방안을 제안하였다. 이를 위하여 한국전력의 대리자, 해상풍력에너지 전력생산 및 판매, 그리고 정전대비 보완사항을 제시하였다. 이 연구로 유비쿼터스 도시에 대한 운영비 조달과 수익창출 및 정전에 의한 재난관리 예방이 기대되고, 유비쿼터스도시의 참조모델이 될 것으로 판단이 된다.

  • 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.

  • A u-city is a vision of a city with computers and sensors built in to its infrastructure, and data sharing among the various information systems. A u-City provides several u-City services to the u-City clients. The u-City services for local governments contain two types of functions: common function and specified function. It is needed a study on generation of specified service models of local governments. The proposed service model divides functions of the city into two service areas: common support service and specified support service. And we suggest the way to generate the u-services of each local government in this paper.

  • 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.

  • The first generation of Japan's smart city policies began around 2010. However, the latest trends in smart city policies and the impacts of the first generation on the latter one were not fully covered in either official documents or academic literature. In such circumstances, the purposes of this study were firstly to identify outcomes derived from the smart city projects in the first generation, and then, to reveal the present situation of the latest smart city policies, including the influence of the first generation on these state of the art policies. The present study was also intended to evaluate the validity of a conceptual framework presented by Fernandez-Anez et al. (2018) for smart city policies. As a result, it was revealed that (1) policy outputs and outcomes derived from the smart city policies in the first generation were highly regarded, (2) the conceptual framework of smart city policies was evaluated as valid, and (3) the second generation of smart city policies after Society 5.0 was characterized by the establishment of smart city platforms.

  • 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.

  • PAJU Book City Plan was designed to integrate two concepts of "Publishing Productive City" and "Ecological City" with the goal of "bringing of human being and nature together". This research on the post occupancy evaluation on PAJU Book City has two aims; One is to define how people, mainly working there rather than living, recognize the city and the other is to identify the problems resulted from the first phase of planning process and to suggest feasible solutions at the same time. It would be desirable that the outcome of this research should be used as data sources to improve the second phase of the plan. The evaluation criteria were created by the pre-survey on the basis of previous researches and "Pa Ju publishing city architectural design guide book (1999)". With those criteria, on-site questionnaire was conducted among people who work in PAJU Book City and stratified sampling was used for the proper sampling. The result is as follows; the visual-aesthetic criteria had positive response, which also closely related to a city satisfaction. Considering this result, construction type, circumferential environment of the building and a place of building form were found appropriate. The evaluation on the physical-ecological criteria was relatively low. Respondents were unsatisfied with green space and required better ecological waterway and more roadside tree. As green space was given a lot of weight in satisfaction survey, more green urban areas should be planned in the next phase. The evaluation on the social-behavior criteria got the lowest score. Particularly, the accessibility and convenient facilities were remarkably low. Nonetheless, the self-conceit about PAJU Book City was highly evaluated and played a crucial role in a city satisfaction. In order to achieve the goal, physical beauty, characteristics as a publication city as well as an ecologically sustainable city should be main agenda in the second phase of Paju Book City Plan. Consequently, it is important to strike a balance between the external environment and image media in order that PAJU Book City should be re-born as a culture city.

  • U-City has been promoted nation-wide by development of recent IT technology. This paper studied the concept of 3D-virtual city in order to realize the current Ubiquitous City(U-City) efficiently, and to manage all the RFID/USN monitoring data in the real U-City. 3D-Virtual City is the concept of the reproduction of real world U-City, for embodying Ubiquitous technology while using Digital map, satellite image, VRML(Virtual Reality Modeling Language). U&V-City is the four-dimensional future city that real-time wire/wireless communication network and 3D-web GIS shall be connected that massive database, intelligent service be perceived through employing EAI(External Authoring Interface) that provides HTML&JAVA, and interface for efficient removal/process of massive information/ service and also by employing GPS/LBS/Navigation in support of world-wide orientation concept, and RTLS(Real Time Location System).
