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.

Ubiquitous City(U-City) is spotlighted for the new paradigm to solve the problem of urbanization using ICT technology. However, due to the lower profit and the insufficient of citizen-experience service, ubiquitous service(U-Service) is perceived negatively. In this sense, a study for user-centric profitable service development is needed. This study, as a basic research for the development of U-service, is conducted to identify the factors which are affected to acceptance of the U-Service. Technology Acceptance Model is applied for the basic model of the research. The model is modified by the U-City characteristic which has user, technology, and service perspective. The proposed model is empirically tested using survey data collected from 600 citizens of 7 U-City. Structural equation modeling is employed to test the research hypotheses. The survey analysis results are able to apply for basic research of U-Service design, and provide theoretical and practical implications.

This research is a part of the Intelligent Urban Facility Management project of the Korean Land Spatialization Group (KGSL). First, this study started from the investigation of existing u-City service model in order to drive essential components and considerations for the urban facilities management system. Considering the driven conclusions, this study finally proposed the new classification system of urban facilities management service model and the adequate application method in u-City.

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.

This paper aims to study the effects of quality of u-City public service on customer satisfaction in the Korea and is summarized as follows. First, we propose a model for assessing customer's satisfaction on u-City public services. The model comprises of information system (IS) quality, information quality, service quality and publicity. For verifying a model, a statistical study by SPSS 12.0 and AMOS 16.0 has been performed. Second, it is shown from the analysis that information system (IS) quality, information quality and publicity have a positive effect on customer satisfaction. while service quality does not. Last, the study shows that u-City public service enables any citizen to connect to necessary service in anytime and anywhere.

U-City means the high-tech city that applied ubiquitous technology and information communication technology. U-City aims to intensify urban competitiveness and to improve the quality of residents' life through efficient management of the urban. Currently, 77 U-City projects is underway. The each project cost and scale estimate is not clear in the absence of the U-Service Standardization Model. So, many of the project are trouble about making a production the proper number of U-Service or the cost of project. The excessive service construction is reflected on the construction costs, which leads to the rise of sales price and passes onto the executor of a project as a burden of the project costs, and the problem of the delay of the change-over occurs due to supporting the operation costs for the operation of the constructed service and the demand for additional installation of facilities between a local autonomous entity and the executor of a project. In this paper, we suggested the U-Services Construction Standardization Methods and proposed the standardization services guideline of crime prevention services. U-City services in the future are able to maintain the consistency of the system through the utilization of the proposed standard model. As a result, the U-City project's pre-estimated cost and scale can be extracted.

Recently, interesting of U-city with ubiquitous computing technologies has increased and u-city services can improve people's quality of life. Among the u-city services, traffice service is actively developed in our lives. In this paper, we propose the business model and business model process in u-intelligence traffic service. To propose the research purpose, we examined the prior business model and investigated u-intelligence traffic information and control services. And also, we draw scenario and used it to identify business model. To efficiently understand proposed business model, we built business model process of u-intelligence traffic information and control services. The results of study, we draw 4 representative U-intelligence traffic information and control service. Based on representative services, we proposed business model and business model process with stakeholder, benefiter and value model. This study concludes with implications of the study results as well as limitations and future research directions.

By the time the interest on the u-City is continuously growing as a test bed for verifying the potentials of ubiquitous convergence industries, research on the u-Safety gradually increases as well, as a typical service and application area of u-City. Like the other service areas of u-City, in order to provide u-Safety services smoothly, it is crucial to integrally connect u-City services and infrastructures that have operated under distributed environment. In this study, we suggest an approach for design of u-Safety service and monitoring architecture by combing CIM/WBEM standard with GMA. CIM/WBEM and GMA are broadly applied in the distributed resource monitoring environment and are widely recognized as data acquisition architecture under massive monitoring data volumes respectively. Considering the growing research needs for standardization and extension of u-City service infrastructure, it is expected that our integrated infrastructure model will be used as a reference model for effective integration of distributed resources with newly added services.

For the development and management of u-City(ubiquitous city), Ubiquitous City Construction Law was enacted(March 3, 2008) to form the legal basis of u-City plan, construction and managements afterwards. The ultimate goal of the u-City construction is the advancement of national territory utilization and management using Korea's high level of IT and spatial information infrastructure. Based on the definition of the u-City Construction Law, the u-City refers to a city where u-City services are provided through the u-City infrastructure applying u-City technology. But, based on the current level of relationship model among u-City service, technology and infrastructure, it is not enough to guide the local municipalities to plan and provide the successful u-City services in its vicinity. So as one of the core issues for the legal arrangements of successful u-City services, the purpose of the study is to suggest the basic directions and execution strategies for the relationship establishment among u-City service, technology and infrastructure.
