The provision of spatial data is a key infrastructural requirement for the promotion of economic growth, environmental quality, social progress, etc. 4S technology integrates 4 kinds of systems that process spatial data: GIS (Geographic Information System), GNSS (Global Navigation Satellite System), ITS (Intelligent Transport System), and SIIS (Spatial Imagery Information System). Spatial data processing field is expected to get synergy effect and overcomes development limit of individual unit technology via 4S technology. This paper discusses both the development of 4S-kernel technology and the construction of 4S-based framework, In the development of 4S kernel technology, we will concentrate on the following issues: the development of 4S base components for reciprocity integration among GIS, SIIS, GNSS and ITS technologies, the development of 4S-Mobile S/W and H/W, 4S-Van components, and national LBS technologies. And in the construction of 4S-based framework, we will especially concentrate on the ISP for overall 4S technologies, the international cooperative research center, and the guide model deduction for supervision and certification of 4S projects. Finally, we examine about how the construction of 4S-baed framework affects 4S industry.

With the growth and maturation of IT industry, the necessity of audit about development, maintenance and management of high-quality information system is gradually increasing. In addition, the necessity of inner auditing system, which could totally verify and evaluate the effectiveness of project according to the characteristics of organization conducting information-oriented business, also being proposed. Government offices including Korea Institute of Science and Technology(KISTI) collectively controlling nationwide science-technology related information have no guiding principle or organization within themselves even though performing information-oriented businesses are becoming more bigger and complicated. In this paper, we propose scheme for devising framework, which can audit construction and operation of knowledge information, check list and guideline. In addition, we present concrete ways for adapting these schemes to institutes which manage science-technology knowledge information. Audit framework consists of points of time in audit, audit domain and audit criterion. Points of time in audit are defined as three phases as followings: pre-audit, in-progress audit and post-audit. Audit domain includes 16 detail audit domains and especially we set 11 check items and 40 detail investigation items for database implementation business. We expect that management level of science-technology implementation business of organizations using this research result will increase and they could offer high-quality information service.

Nowadays PMIS (Project Management Information System) based on web is widely applied to communication, collaboration and community in construction jobsite for various organization such as subcontractors, general contractor, engineering company, supervisors and client. However, individual PMIS in jobsite is prone to be troublesome issue for integration and exchange of information regarding project management in corporate and may result in conflict of data application. The main reason should be lack of information strategy plan such as company master plan for information. This research shows a critical success factor that a big construction company of Korea establishes procedure and method for information strategy plan. In addition, It is to suggest how to be implemented PMIS architecture and execute business process innovation in corporate level. This research expects contribution that many construction companies reduce mistakes to be implemented management information system and to optimize system in corporate level.

Digital documentation is now becoming a must throughout a building process including design, construction, inspection, procurement and even facility management. The Internet is a backbone of such process, and web-based information exchange is the standard among other mainstream technologies. The current information management techniques, however, is heavily dependant on the server-side processing, which naturally results in the overload of the overall system. This paper proposes an XML-based approach in order to resolve such problems. A VE system was developed to demonstrate the efficiency of the XML solution, in term of efficient VE data management and fast decision making. also in this paper suggests 1) introduce XML based DBMS to improve data management efficiency and 2) introduce Mobile Computing to improve data accessibilities on sites.

As the field report data does not normalize, ordering organization requires different form every time and field reporters make out form as random, data and report to the ordering organization by different medium such as FAX, e-mail, paper document. Therefore, Field reporters must set and make out same information in required pattern. And ordering organization is being responsible for side works of totalizing and processing the reported data. This research suggests the electronic document unification about monthly construction progress report and construction present condition report system. In addition, it suggests electronically processing function that can handle field report business to unifying electronic documents. As using the result of this research, it will improve the work efficiency and simplify in report business.

This research is to suggest the factor which is effecting on the information system audit fidelity in the perspective of audit procurer, to develop the measure to evaluate it, to investigate the audit performance and project performance for comparison the audit fidelity between the audit teams. As the analysis results, we found that the audit service factors can be divided to the expert knowledge of auditor and the project attributes itself. It means these factors are the major measures for the audit fidelity. In this research, the hypothesis of this study model is verified throughout the factor and corelation analysis, and the structured equation model is applied. Analysis results show that all relations between the factors are significant statistically. The audit service factors has an effect on audit fidelity. Also the information system audit fidelity can be affect on the project performance, audit performance and customer satisfaction. So, in conclusion, we need to judge closely the audit service factors affecting the audit fidelity for the enhancement of the project performance, audit performance and customer satisfaction.

The National Computerization Agency has been leading the Information Systems(IS) audit since 1987, as development of IS projects in governmental and public sectors have become daily issues. While many considerations on audit guidelines and techniques for quality management in IS have been given to respond to the fast increasing demand of audit process since mid 1990's, the study on the fact that how audit activities directly affect the quality of software process has been put aside. In this paper, we went through 74 audit results, which were reported by H auditing organization, and performed on 59 IS projects carried on 1999 through 2001. As a result of study, we found that more than one fourth of errors of Coding and Test phases are caused in the earlier phases, which naturally leads to the conclusions that auditing on earlier phases can save a lot of stitches in the later phases. Comparing two types of IS projects-the one that went through only one audit process, and the other that went through two audit processes-, we found that projects with two audits carry less errors on Planning, Analysis, Design phases as a whole, which revealed the facts that IS audit actually gives positive effects on the quality of software.

The core infra-technology in the ubiquitous era, RFID which has taken action from the public institution with the pilot projects as well as the practical projects is gradually extending its spectrum to the private enterprises. Along with its expansion, the audit required on the RFID-based information system is also growing in the industry. Especially, since RFID-based information systems, especially compared to other information systems, are likely to be exposed to many threats, the security audit for them is being emphasized. This paper suggests security audit checking items for the RFID-based information system, which can be used to perform the efficient security audit. The security audit checking items consist of eight basic checking items, each of which consists of detailed review items and can be applied for each building steps of the system(analysis, design, implementation, testing, and development). Finally, this paper confirmed the efficiency of the security audit checking items proposed in this paper through survey by the experienced auditors and analysis of practical audit cases.
