유비쿼터스 도시의 개념이 등장하면서 도시관리에 대한 중요성이 점차 부각되어가고 있다. 특히 지하시설물에 대한 안전한 관리는 안전한 도시를 표방하는 유시티 에서는 없어서는 안될 중요한 공공서비스라 할 수 있다. 최근 이러한 도시의 지하시설물의 안전한 관리를 위한 체계적인 관리 방안에 대한 연구가 국토해양부를 중심으로 활발히 이루어지고 있다. 지하시설물의 특성상 안전하고 체계적인 관리를 위해서는 무엇보다 지하시설물에 대한 정확한 위치좌표를 알아야 하고 지하시설물에 일어나는 변화에 대한 정보를 수집하기 위해 센서적용기술을 필요로 한다. 본 논문에서는 유비쿼터스 도시 내 지하시설물 구축과정에서의 절대위치확보 방안과 각 지하매설물별 특성을 고려한 센서적용방안에 대한 내용을 기술하였다.

In recent years, our society, because of the arrival of a new paradigm according to the rapid changes in ICT has entered into future smart society and the ubiquitous era. So it can be a notable turning point in the city disaster prevention system with big data, aspects of the era change. Therefore, this study was to derive a desirable vision for the big data city disaster prevention informatization in terms of ICT city disaster prevention system development as preparedness for the city disaster by applying 'scenario planning' as a foresight method. Soon this study derived a successful city disaster prevention informatization strategy as preparedness for the city disaster, for example, in terms of water pollution and disaster prevention of Busan Ecodeltacity. It proposed the big data city disaster prevention informatization system with the use of the administrative aspects of information with spatial informatization as big data information. Also this study explored the future leadership strategy of the big data city disaster prevention informatization in smart society and smart eco-city. Eventually in 2030 to around, in order to still remain our city disaster prevention informatization as a leading ICT nation, this study suggested the following strategy. It is important to ready the advanced ubiquitous administrative spatial informatization and ICT disaster prevention system with big data in terms of water pollution and disaster prevention of Busan Ecodeltacity.

Recently, interesting of u-city with ubiquitous computing technologies has increased. In this paper, we propose u-service model for urban facility management based on ubiquitous computing technologies. To propose the research purpose, we define business model for the service and u-service model. And, we propose service function, service process, and relationships between participants to give shape to u-service model. First, we present five service functions; remote monitoring, remote control and inquire, state information, field support, and facility history information. And, we propose overall service process and demand-supply relationship between participants.

This paper presents the main business models in ubiquitous city (u-City), the future city strategically integrated with the ubiquitous computing technology. Based on the concept of u-City, the chief services related to the u-City that has been actively developed are analysed, and then the best main four business models (u-Tour, u-ITS, u-SCM and B2B) for SongTan city are presented. The four business models are selected from making an analysis for the present situation of the tour industries, industrial complex, traditional market in SongTan. With the business models, the strategies to realize the active business transactions, high revenues, high value-adding industries, self-sufficient business through the construction of u-City are also presented. Finally, the promoting plans for local autonomy party, citizen party and consortium of industries/universities/researches to give an comfortable u-Life to citizen in SongTan are described.

유비쿼터스 사회가 도래함에 따라 유비쿼터스 기술을 도시에 적용한 u-City가 개발되고 있다. u-City는 다양한 정보화 기기들이 존재하며 정보화 기기 사이를 연결하는 다양한 네트워크 기술이 상존한다. u-City의 핵심 요소인 u-City 통합운영센터는 u-City 내의 모든 서비스를 처리하도록 설계되었으며, 도시를 통제 관리하는 중요한 업무를 수행한다. 이 중에서 보안관리 업무는 시스템에서 수집, 가공, 산출하는 데이터 및 정보의 보안유지를 위해 중요한 부분이다. 따라서 본 논문에서는 u-City 통합운영센터의 보안유지를 위한 기술적, 물리적, 관리적인 측면에서 보안관리 대책을 제시하였다.

유비쿼터스라는 새로운 패러다임의 등장과 IT 기술의 급격한 발전에 힘입어 도시에 유비쿼터스 기술을 적용하여 도시민의 삶의 질과 경쟁력을 향상시키는 도시, 즉 u-City가 다양한 차원에서 추진 중에 있다. 효율적인 u-City 구현을 위해서는 다양한 시도들이 한데 묶여 진정한 u-City로써의 시너지 효과를 내는 것이다. 이를 위해 현 시점에서의 상황을 직시하고 관련 정책 및 사업에 대한 계속적인 모니터링을 통해 국토, 도시, 교통, 환경, 행정, 문화 등 모든 것이 한데 어우러져 최고의 효과를 가져 올수 있는 진정한 u-City 개발이 필요할 것이다. 이에 본 연구에서는 여러 부처에서 진행/계획 중인 u-City 관련 연구 및 사업의 여건분석을 통해 문제점을 도출하고 효과적인 u-City 발전 방안에 대해 고찰해 보고자 한다.

우리나라는 1960년대 이후 급격한 산업화로 인해 도시의 구조가 변화하기 시작하였으며 2004년 이후부터 대두된 유비쿼터스 도시(U-City)는 사회 각 분야에서 논의가 본격화되고 있다. U-City는 언제 어디서나 도시의 경쟁력과 삶의 질을 향상하기 위해 유비쿼터스기술을 도입한 도시 내 서비스가 제공되는 것이며 현재 우리나라의 U-City는 체계적인 서비스 도출 방법이 미흡한 실정이다. 이러한 문제점을 바탕으로 본 연구에서는 4개의 특징적인 가로를 대상으로 U-서비스를 비교 분석하여 향후 체계적인 서비스 도출 방안과 지속적인 서비스 운영 방안, 이용자 중심의 서비스 도출 방안에 대해 기본방향을 제시하고자 한다.

Recently, discussions about the guarantee of smart ecological environment have been started in S. Korea. These discussions are becoming more and more popular in the aspect of ubiquitous administrative spatial informatization in utilization using big data as a new paradigm due to the rapid change of information and communication technology, such as the start of smart society and the ubiquitous era. In addition, there is a growing interest in discussing environmental and disaster preservation in terms of ubiquitous smart city construction in smart society. In thisstudy, by applying 'scenario planning' as a foresight method, we have developed a desirable future vision for ubiquitous administrative spatial informatization in terms of preservation of disaster of Kori nuclear power plant like earthquake. In order to establish a high level of city disaster prevention level in S. Korea in 2030 when the big data and big data System will be further intensified in the future, it is necessary to develop advanced ICT city disaster prevention system with big data administrative spatial informatization in terms ofsmart ecological city construction.

The ubiquitous technology is capable of innovating various area to constructing intelligent and network to all objects. This technology can construct network infrastructure to facilities for applying legacy industry and need to develop intelligent service that analyze context-aware through network. This paper derive and propose the introduction range of ubiquitous technology, which should be testified and analyzed network, and studied the detection and analysis of information for managing gas facilities. We investigate the current status of gas facilities and automatic reading system, testing and analyzing wireless personal area network and mobile communication by scalability, self-configuration, connection in underground. Furthermore, we propose modelization method for intelligent service and derive the introduction range for applying ubiquitous technologies for managing gas facilities.

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.
