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.

국가의 신성장 동력으로써 유비쿼터스 도시(U-City) 개발이 추진되고 있다. U-City는 국가 차원에서 수행되는 미래전략 프로젝트이며, 도시의 다양한 문제점들을 해결하여 지속가능한 도시 조성에 그 목적이 있다. 또한, 전 세계적으로도 미래도시 연구의 선도적인 역할을 하고 있으며, 정부, 산업계를 비롯하여 학계에서도 U-City 개발과 관련한 다양한 연구가 진행되고 있다. 하지만, 무분별한 사업 추진과 장기적인 효과에 대한 가시적인 평가가 이루어지고 있지 않기 때문에 자칫 하면 난개발이 될 수 있다는 우려가 발생하고 있다. 따라서, 이러한 문제점들을 극복하고 보다 안정적인 개발이 이루어지기 위해서는 U-City 사업평가에 대한 근본적인 고찰이 필요할 것으로 보인다. 본 연구에서는 U-City 사업을 점검하기 위한 평가체계를 제시하고, U-City에 적용하여 평가체계의 활용방안을 논하고자 한다.

U-City건설사업이 시작된 지 수년이 지났지만 아직도 우리가 U-City를 인지하고 체감하기에는 부족한 것이 사실이다. 그러한 원인 중에 하나는 U-City가 그 속성상 보다 체계적인 개발과 제도적 관리가 요구됨에도 가시적인 성과만을 위해 개별사업자를 중심으로 한 난개발에 있다고 볼수 있다. 다행히도 올 3월 U-City의 계획, 건설, 운영관리 등을 위한 "유비쿼터스도시의 건설 등에 관한 법률"이 공포되고 앞으로는 관련법률에 의해 체계적으로 U-City가 추진될 것으로 보여 이런 상황은 상당부분 해소될 것으로 예상된다. 이에 본 연구에서는 과거 각 지자체들의 U-City 건설사업절차와 문제점들을 분석하고 BPR방법론을 이용하여 새로운 법률에 맞춰 U-City건설사업 프로세스를 재설계함으로써 체계적인 사업추진을 통해 지속가능한 U-City의 개발이 될 수 있도록 하는데 그 목적을 두었다.

현재 국내에서는 정부 및 지자체를 중심으로 u-City를 도시의 핵심 성장 동력으로 인식하고 활발하게 사업을 추진 중에 있다. 그러나 도시의 목표나 특성에 적합한 서비스 도출을 위한 선정방법이 미흡하여, 한정된 예산과 도시 전 분야에 걸친 과다한 서비스, 복잡한 이해관계로 인한 사업비용과 시간지연, 낮은 서비스 수준 등의 문제를 안고 있다. 본 연구는 이러한 문제를 해결하고자 새로운 u-서비스군 선정방법론을 제안하고 있다. 제안한 u-서비스군 선정방법론은 법 제도나 기술제약의 엄격한 적용과 다양한 변수를 통해 서비스군의 가치를 산출하였고, 서비스군의 다양한 조합으로부터 최적의 서비스군을 선정할 수 있는 가치평가모형(u-SEM)을 제시하고 있다. 특히 본 모형은 사업추진상의 복잡도로 나타나는 비우호적이고 영향력이 높은 이해관계자의 수를 가치평가의 중요한 요인으로 포함하였고, 궁극적으로 복수의 u-서비스군 대안을 경제효과, 복잡성, 구축비용 등으로 종합 평가할 수 있는 방법론을 제시하고 있다.

As a leading nation of ubiquitous technology, South Korea has been promoting u-City pilot projects throughout the country. According to 'Fundamental Construction Law of u-City,' u-City projects are classified into old-town and new-town types. However, most projects have focused only on the new-town type. Pushing forward large-scale land development projects, Korea Land and Housing Corporation (LH Co.) under Ministry of Land Transport and Maritime Affairs (MLTM) has gained a development profit out of the u-City infrastructure and then donated the infrastructure to a local government without making any plan for operations. In the process of u-City pilot projects, old-towns have been relatively ignored and various of unexpected problems have emerged. Building the u-City of an old-town is not easy due to many constraints such as huge initial investment, long validity and verification procedures, lack of useful services for citizens, lack of professional outsourcing methods for business promotion, high operating costs of the integrated control center, inadequate law related, insufficient institutional requirements and so on. This paper introduces a case study on u-City development for an old-town, Ansan City, as a private investment project. The case will help boost u-City projects for old-towns by solving their problems and providing an effective operational mechanism. As the first BTL (Build-Transfer-Lease) project for constructing u-City, 'Broadband Information Network Development Project' of Ansan City will provide a reference model of expanding u-City projects for other cities.

u-City사업은 기존의 도시개발 사업과 달리 IT기술과의 융합을 통하여 진행된다. 따라서 기존의 개발사업의 비하여 더 많은 복잡성, 다양성을 내포하여 더 많은 위험요인들을 내제하고 있다. 이러한 리스크 요인들을 체계적으로 확인하고 정량화하여 관리, 통제할 수 있는 리스크 관리체계에 대한 필요하다. 특히 계획단계는 그 위험 요인이 다양한 형태로 나타나게 되어 사업의 성패에 많은 영향을 주는 단계이지만, 위험요인에 대한 관리는 소극적인 형식에 머물러 있다. 이러한 상황에서 리스크 요인들의 식별과 분석을 통한 리스크관리는 가장 필요한 요소이다. 따라서 본 연구에서는 u-City 사업의 지속적인 성장과 성공적인 수행을 위하여 계획단계에서의 문제점과 기존의 개발사업의 리스크 요인을 분석하여, u-City 계획단계에서 관리되어야 할 리스크 인자를 식별하고 이를 통계적 기법을 활용하여 리스크의 중요도, 발생확률, 발생영향에 따라 리스크 요인을 분석하여 정량화 하였다. 이를 통하여 우선적으로 관리되어야 할 핵심리스크 요인을 도출하였으며, u-City사업의 효과적인 리스크 관리를 위한 기초자료를 마련하였다.

Recently, the construction of U-City or of U-City service (U-service) in many kinds of urban development projects becomes the general trend. However, as the construction of U-city comes into the spotlight like the trend of the times, various service constructions are being indiscreetly implemented since it's processed focusing on local specialized projects or local landmark project by a local autonomous entity or an institute in charge being off the original purpose of the improvement of living quality of residents and the efficiency of urban management, which causes a number of problems on the process, maintenance, operation and management of those projects. Therefore, this study is to derive the standard pattern of U-service construction through the analysis of patterns and numbers of U-service and problems during the process of construction in domestic U-City construction case district, and is aimed to suggest the reasonable direction of service construction based on this. 11 projects areas in which data related to U-service are available among U-City construction project areas were selected for the subjects of this study, and it's standardized with 228 detailed unit services that were suggested by U-Eco City R&D and with 11 service domains that are regulated in "the Act of ubiquitous city construction etc.", and it is limited to services that were suggested in U-City case area of which design was completed by July, 2010 based on this. The actual state of various U-service construction is analyzed through case studies as well as reviews on the legal and theoretical concept and the method of pattern classification of U-service, the plan for the standardization (pattern classification) of U-service and the plan for the construction body of service and to share the costs are suggested as the plan to construct reasonable U-service based on this for the method and the procedure of this study For the method to construct U-service, the plan to classify the pattern of U-service into the basic service and additional service is suggested, and whether it has the publicity, whether urban infrastructure is included, whether utilities are included, the body of realization, the recipients, the urgency, the importance and the spreading, etc. are suggested for the index to determine the pattern of service. The method to get the executor of a project to construct the basic service, the method to get the executor of a project to construct the most basic service among the group classification of service and to get a private entity and a local autonomous entity to perform additional service in the future, and the method to construct the whole service and to distribute the construction costs were suggested, and the first one that determines the body of construction after dividing U-service into the basic service and the additional service was evaluated to be the most reasonable one. And the plan to solve the problem that the excessive construction costs of U-service are shifted onto the executor of a project through benefit principle, balanced distribution principle and consultation and mediation between the interested parties was suggested for the criteria to share the costs.

This paper analyzed articles of u-City Construction Law, which has been enacted on 29th of September last year, and evaluated their appropriateness and other laws associated with u-city services for better provision of u-cities and u-city services. The enacted law established the concept of u-city in Korea and provided relating industries with construction procedures, technology developments, and standards. These efforts have substantial implications as the first stepping stone, but also raised several problems. Hence, this paper suggested that the u-City Construction Law should be amended as follows. First, The minimum size of u-cities, that is required by the law, should be decreased. Second, various kinds of incentives should be provided to the u-city project companies. Third, new organizations such as u-City commission and National or Regional Control and Management Center will be necessary. Fourth, technology standards and inter-operability among cities should be provided in the areas of the control and management centers. And Finally, more measures of and focuses on project financing issues should be made.

In recent year, the u-City construction projects which integrate IT technology into urban infrastructures are being pushed forward by many local governments. These projects contain various purposes in an aspect of regional economy : to reinforce a competitiveness of region by increasing efficiency of urban managements and to revitalize regional economy by stimulating the regional high-tech industries that related to u-City construction. In this context, regional economic impact assessment of u-City construction projects is particularly important because, it give us information about effectiveness of u-City construction policy as a stimulus of regional high-tech industries and the policy feasibility of u-City construction projects that can be a base of public projects. However, it is challenging to assess the impact of u-City projects on regional economy properly due to a lack of understanding about industrial classification, and specific industrial inputs related to u-City construction. In this study, we suggest u-City industrial classifications, and specific-industrial inputs induced by u-City construction projects based on associated legislations, business report for a u-City construction, and results from previous studies. Using these classification and industrial input, we also investigate the regional economic impacts of a u-City construction project in Wha-sung and Dong-tan cities employing Input-output analysis. The empirical results suggests that u-City industries have relatively high in production inducement, and value added inducement compared to input of other industrial sectors. These results indicate that regional economic impact of a Wha-sung and Dong-tan u-City construction project are relatively high, but economic impacts of u-City construction projects vary according to the regional industrial structure, and the specific expense accounts of u-City construction projects.

The u-City construction project has become a hot topic in the construction market because it seems economic value-added field for construction firms. However, construction firms don't willingly participate in the u-City construction market because environments of the future business for the u-City are very uncertain. Scenario planning is a very powerful method in managing this uncertain planning situation and is based on scenarios that help each enterprise appropriately adapt itself to its own business environments. Therefore it is based on the main principles of systems thinking and multiple futures. For the purpose of dealing with such uncertainties, this paper attempts to develop the possible market scenarios of the u-City construction market in S.Korea through a scenario planning approach. From this perspective, we considered various aspects of the u-City construction such as market demands, technology development, policy level and management environment. After considering the relevant issues, we identified the main trends and key uncertainties. Finally, we developed three coherent u-City construction market scenarios. Construction firms can use these scenarios as a basic reference for market analysis and business strategy. Therefore, this paper is able to enhance the participation of construction firms in the u-City construction market.
