Congestion index is needed for quantifying congestion level for various areas. So far, the index has been calculated based on multiple vehicle data for specified time interval. Such being the case, it was costly to build it and the usage of it was focused on policy development and evaluation rather than on traffic information provision. This study focuses on a development on a single vehicle based congestion index which can be a representative value for link congestion level and link speed information at the same time for dual purposes of traditional usages and information provision. A new term has been added for representing real time based arterial congestion level and it has been verified on a real time basis. The index was based on single vehicle GPS data and seemed to be cost effective in deriving the index. With the help of the index, the traffic information contents can be diversified in a constructive way in providing real time traffic information for ITS area and in using congestion level determination for traditional transportation areas.

Purpose The purpose of the study is to identify the need of a mobile based library information and service delivery system in developing countries, identify the services that are possible to provide with the help of mobile phones and their applications, design a mobile based library information and service delivery system, and identify major challenges regarding mobile based library information and service delivery systems.Design/ Methodology/ Approach The research is exploratory in nature. This paper is based on a review of literature, survey information, and on the author’s own viewpoints. A comprehensive search of scientific literature has been done along with a survey for validating the necessity of designing mobile based library information and service delivery systems. Responses to closed-ended questions in particular on 7-point Likert scales were analyzed using the descriptive analysis techniques of SPSS 20.0 and responses to other closed-ended questions were analyzed using general statistics.Findings The research indicates that users of academic libraries, especially students and faculty members, have a positive notion regarding designing and implementing a mobile based library information and service delivery system. It also reveals user opinions regarding the possible problems associated with the design and implementation of a mobile based library information and service delivery system.Originality The paper explores mobile based library information and service delivery systems for better and faster service provision to its potential users.

The extensive coverage and high speed of communication network, which is a basic structure of the information society, enables the provision of various forms of informatiov. especially, such services as cyber medicine, cyber education, home office, home banking, and home shopping will be common; and, now, no one can deny that the information society starts to be part of our life. Regarding home office, John Navigate predicted home office through the electronic house in New Mecca Trend and Alvin Toffler asserted in The third Wave that people could do their work anywhere including living room in their hoses with the development of communication technology and other related appliances. Such predictions are realized with the development of information communicatiov. Therefore, housing space should be changed according to the realization of home office and the direction of housing plan need to be set for home office.

Efficient extraction and update of imagery is a crucial element in establishing latest geospatial information in today's fast changing Information society. Provision of Quick Bird imagery, with 61cm resolution panchromatic imagery and 2.5m resolution multi-chromatic imagery is contributing greatly in the application field if high density geospatial information. This research have conducted digital plotting utilizing stereo images provided by QuickBird satellite and evaluated the accuracy through comparison and analysis with digital map results. It turned out that result has smaller error than standard deviation of scale of 1:5,000 set by the NGII. This proves that the production of digital map at scale of 1:5,000 is possible.

Proportion and importance of knowledge & information provision through the web are increased continuously. Equivalent accessibility focused on universal service is highly demanded especially for public institutions, such as national libraries. In this study, web accessibility of sixteen national libraries were compared and analyzed by KADO-WAH, web accessibility tool. Characteristics of libraries were investigated and future directions were suggested based on the analysis and results.

This paper proposes the new high precision monitoring sensor for the Marine Installation. Among variety of sensor network systems, wireless information transmission through the marine is one of the enabling technologies for the development of future marine-observation systems and sensor networks. Applications of marine monitoring range from oil industry to aquaculture, and include instrument monitoring, pollution control, climate recording, prediction of natural disturbances. For these marine applications to be available, however, the provision of precise location information using monitoring sensor is essential. In this paper, the dynamic characteristics for obtaining the location information of monitoring sensor is analyzed. The theoretical and experimental studies have been carried out. The presented results from the above investigation show considerably excellent performance for the Monitoring for the Marine Installation.

Urban regeneration is a large-scale program that must address challenges such as a significant number of involved projects, diverse participants and their conflicting objectives, and a long life span. In an effort to address these issues, the Interactive Electronic Technical Manual (IETM) is applied to urban regeneration in order to provide a guideline to enhance urban regeneration program management. Through a survey, three major functionalities required in the IETM are identified: process map provision, customized information delivery, and communication ability with other information systems. To achieve these functionalities, the development framework of the IETM and the associated technologies are examined.Its characteristics can be sum up ontology-driven metadata, user-oriented process map composition system and so on. Finally, the usage scenarios of the IETM are discussed.

Electronic commerce has already existed for over 20 years. In sectors such as retail and automotive, electronic data interchange(EDI) for application-to-application interaction is being used regularly. For defence and heavy manufacturing, electronic commerce life-cycle management concepts have been developed that aim to integrate information across larger parts of the value chain, from design to maintenance, such as CALS(Computer Assisted Life-cycle Support or Computer Aided Logistics Support). Bolero's mission is to provide guaranteed and secure delivery, in electronic form, of trade documentation, globally, based on a binding legal environment and common procedures. Bolero will also provide a platform for provision of neutral cross-industry services.
