The international society under the internet technology have been declining boundaries of the global economy. After this step, a social revolution will be happen from the ubiquitous technology which gives objects intelligence to serve people. And then it is expected that every part of a city competitive power is defined by both in quality and in quantity of the ubiquitous information unit in the future. On this score, now each nation is trying to set relative services and broadband networks to lead the ubiquitous industry. Therefore this paper analyzed about the progress and prospect of a local U-city plan in our nation. And than we propose a method of configurating broadband self-communication network on the base of cost and utilization Especially we propose a new city development model which use U-city and self-communication network to improve a city competitive power.

Recently, with the advance of Ubiquitous era, the types of services become diverse. Especially, due to the rapid development of mobile technology, the new functions of mobile phones are added and the new applications of mobile phones are developed actively. Among the various applications related to mobile phones, 2 dimensional barcode-based applications are increasing. 2 dimensional barcode is mostly used for the management of past record. However, by combing 2 dimensional barcode with mobile phones, the application areas of 2 dimensional barcode are expanded to the means of publicity for education, tourism, and festivals. In this paper, we develop a QR code decoder running on smartphones, which connects on-line and off-line. In addition, we modify our decoder by detecting the point for performance enhancement based on TRIZ. We compare our decoder with an open-source based decoder in terms of the code size of decoding and the speed of decoding in order to prove that our decoder has a better performance than the other. Finally, we introduce two applications: u-map and u-pamphlet as QR code applications.

Ubiquitous tourism information systems are more and more required to provide cultural contents comprising material heritage, performing art, folk tradition, handicraft or customs of everyday life, along with traditional tourist information about hotel facilities and infrastructure. This study attempts to investigate the effect of tourists' hotel preference attributes in terms of their satisfaction with ubiquitous tourism service. In so doing, 145 questionnaires were used to analyze the satisfaction of u-tourism service and the hotel preference attributes through the field survey. The questionnaires were collected from hotel employees who had experienced the ubiquitous tourism service. It is found that some of hotel-preference attributes positively influence u-tourism satisfaction but not all of them did. Service and differentiation attributes had an impact to u-tour and u-hotel function. And beverage attributes, to u-tour function, and convenience attributes, to u-hotel function. These findings mean that the hotel built u-tourism infrastructure gain a competitive advantage than the otherwise hotel.

How can new media devices and networks provide an effective response to the world's growing sector of cultural and historically-minded travelers? This study emerged from the question of how mobile handsets can change the nature of cultural and historical tourism in ubiquitous city environments. As wireless network and mobile IT have rapidly developed, it becomes possible to deliver cultural and historical information on the site through mobile handset as a tour guidance system. The paper describes the development of a new type of mobile tourism platform for site-specific cultural and historical information. The central objective of the project was to organize this cultural and historical walking tour around the mobile handset and its unique advantages (i.e. portability, multi-media capacity, access to wireless internet, and location-awareness potential) and then integrate the tour with a historical story and role-playing game that would deepen the mobile user's interest in the sites being visited, and enhance his or her overall experience of the area. The project was based on twelve locations that were culturally and historically significant to Korean War era in Busan. After the mobile tour game prototype was developed for this route, it was evaluated at the 10th PIFF (Pusan International Film Festival). After use test, some new strategies for developing mobile "edutainment content" to deliver cultural historical contents of the location were discussed. Combining 'edutainment' with a cultural and historical mobile walking tour brings a new dimension to existing approaches of the tourism and mobile content industry.

Mobile network evolution and development of USN technologies introduce new business model based on context awareness. Cellular operators provide friend finding service using cell based location information and telematics service using GPS location information. Recently cellular operators provide yellow page service based cell based location information. In this paper, we develop mobile tour application on WIPI platform based on location information. Mobile tour information services provide the best information based on context awareness using user location information from LBS(Location Based Service) Platform, season, weather conditions, time from Web server, and personal preference information stored in database. Mobile tour information service application is developed on WIPI platform.

The rapid development of the information technology has passed over the implementation of the virtual reality. It is realizing information services that are form of the globalization, based on the Internet. In addition, the effort to apply IT to public administration for public services has been made. The remarkable development of computer hardware has overcome the limit of the information distribution and emerged for practical use in various fields such as public institution, underground facilities management, tourism industry development etc. However, the practical use of Virtual Reality with Three-Dimensional GIS on disaster management by Korea National Emergency Management Agency is very much low. Therefore, this studies focus on how to use 3-Dimensional GIS for the purpose of fire disaster prevention. The studies also discussed, through understanding of the limitations of 2-Dimensional GIS, the establishment of basis for fire prevention technology development and its utilization among those ubiquitous city paradigms, which have become so much issues these days.

This paper presents real-time online early fire warning systems developed for preserving cultural properties of Bulguksa which is a world heritage designated by UNESCO. The system is based on the ubiquitous sensor network employing 900MHz and 2.4GHz bands. In this paper, we analyze requirements that should be considered in building effective management systems of cultural heritages by using wireless sensor network. Finally, we introduce the architecture, sensor and network design, and software design of the fire warning systems which is an initial version of U-Bulguksa. The current version of systems has been operating in Bukguksa for a few months. U-Bukguksa project sponsored by National Information Society Agency is ultimately aimed at developing an integrated system of U-cultural heritage management and U-tourism. The former aims to conserve and manage intangible cultural properties by providing a variety of environmental information such as erosion, crack, and gradient as well as fire which are important causes of loss and damage in real-time and online. The latter refers to the intelligent tourism information and guidance systems allowing tourists to get the personalized content on cultural heritages and help guidance with mobile devices in Bulguksa.

In this study, the operation condition of the U-library services is identified, and after confirming if there is any difference in the recognition from librarians, based on the results, the U-library services explore ways improvement plan to be operated reasonably. This study selected 10 local governments supported of the Ministry of Culture was performed in U-library services as a subject of study. Whether is any difference in the perception of librarians were measured according to demographic factors of librarians, presence or absence of work independency, employment pattern difference of librarians mainly operating U-library service as U-library services operating difference. For this study, united research methods (survey, visit, phone call) were used.
