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.

With the obligation of information system supervision and an increase in supervision demands, the quality improvement in information system supervision has been of significance, and the supervision system has been enhanced in the way of preventing information systems from being poorly established. In the meantime, recently the supervision industry has received administrative punishment due to violation of supervision guidelines and false reports. As a result, the introduction of the responsible supervision of information systems to strengthen the rights and duties of supervisors and supervision corporations has been discussed by supervision corporations. Therefore, this work was intended to propose success factors to introduce responsible supervision in the information system supervision sector, and thereby contribute to the introduction of responsible supervision system that plays a successful role in preventing poor supervision and establishing information system business. The success factors of the responsible supervision of information systems, proposed in this work, were categorized into legal system, standardization of supervision work, those concerned with supervision. And, detailed success factors of each category were proposed, and on the basis of that, the success model to introduce responsible supervision successfully was proposed.

Enterprise should determine the adoption and utilization of information systems would be a great help to increase management performance. So, it maintains continually the budget and the investment for informatization. However, there is a limit to clarify whether the investment in informatization is contributed to create business opportunities through corporate competitiveness certainty or not. We tend to recognize the information system as a simple means to support common business rather than being used to achieve the company's business performance and to remain competitive. It is not an easy problem for the quantitative evaluation and analysis on the effect of intangible, such as management performance measurement by introducing computerization project. Informatization level evaluation model for the harsh business environment, specifically the Small and Medium Enterprise is lacking. In this paper, we proposed the audit evaluation model of an Small and Medium Enterprise informatization level based on system quality, information quality, user satisfaction, and IT business contribution. The proposed audit evaluation model was evaluated in the information system users, and verified the suitability throughout the survey of the audit professionals.

The architectural drawing, construction project specification, etc. are included in the contract of a documents. However, construction project specification, for being documentation, is not utilized to such an extent. The reason is that specification information is difficult in collecting information in relation to the architectural drawing, material finishing list and other architectural information. Therefore, an integrated model, which can be associated with other architectural information, is needed, and a DB based on this integrated model must be established in order for it to be utilized in design, construction, and management. The DB, which is established through this process, must be updated according to modification in design, and construction. Furthermore the specification must be in document on the web for reference. Consequently in this research, the structure of integrated model has been introduced, and it has made the search and preparation of the integrated model on the Internet, using the specification information DB established for the mutual reference of DB, possible. The improvements of construction project specification standards are expected by this system. Also, it will bring about Improvements upon claim prevention, and design, construction, management qualities. Furthermore, it will make the use of information more convenient in practical business such as order agency, design service and building site.

The considerable budgets for the 2nd-phase NGIS projects are allocated to the projects for developments of the GIS applications. Especially, the 78 local governments are major users of GIS application systems. In spite of GIS necessity in local government, whether a GIS is 'good' or bad, depends on its implementation and operation. How to implement GIS in effective wav and how to measure GIS effect for justifying GIS funding can be major concerns. Because it takes minimum 3-4 years to equal the costs and benefits of GIS, the long-terms implementation strategies for GIS project in local government are required. In order to establish a proper implementation model for the GIS application projects and to promote activities in the projects, this study considers several problems in accordance with the phases of GIS evolution and solutions of these problems. Based an the GIS auditing and consulting experience in local governments, this study constructs a GIS implementation and maintenance model in long and comprehensive perspective. This model can be a key to affective and realistic implementation for the future GIS projects.

Recently, two international standard organizations, ISO and OGC, have done the work of standardization for GIS. Current standardization work for providing interoperability among GIS DB focuses on the design of open interfaces. But, this work has not considered procedures and methods for designing GIS DB. Eventually, GIS DB has its own model. When we share the data by open interface among heterogeneous GIS DB, differences between models result in the loss of information. Our aim in this paper is to revise the design guidelines for geographic information databases in order to make consistent spatial data models, logical structures, and semantic structure of populated geographical databases. In details, we propose standard guidelines which convert ISO abstract schema into relation model, object-relation model, object-centered model, and geometry-centered model. Furthermore, we provide sample models for applying these guidelines in commercial GIS S/Ws. Building GIS DB based on design guidelines proposed in the paper has the following advantages: the interoperability among databases, the standardization of schema definitions, and the catalogue of GIS databases through.
