Old maps are a cultural heritage of recorded information with humanities materials and scientific value. However, there is no sufficient study on the development of web-based information system using old maps to provide the old map information. In this study, we analyze the status of the old map information on the website of the main institutions, construct the web-based information systems to provide the unified map information efficiently and systematically. It is not easy to standardize the data categories and information searching method because of the diversity and complexity of old map. So, the importance of engineering information management is growing. Therefore, the attempting to computerized humanistic old map information and the integrated approach is very important and necessary. This study provide an opportunity to combine the humanities and engineering through the convergence between information technology, humanities, and computational engineering.

Nowadays, IS projects are getting more complicated and large-scaled. Therefore, many researchers and practitioners have been interested in the IS development methodologies, automated tools, techniques, and TQM to improve IS performance. Latest Standish Group's research reported that after the PMO introduction, project scale became bulkier than 1 or 2 year ago, and that IS development project success probability was increased sharply by 62 percents from 37. The previous researches listed just various PMO functions. This research is to seize the core functions and management level of the PMO affecting on the IS project performance with banks which are the leading industry to accept the PMO in Korea. The activities in the categories of implementation management technology support management infrastructure management are the core functions of the PMO to affect the IS performance including schedule management quality management user and stakeholders' satisfaction. Also, the PMO management level is important for IS project success. Among the 5 levels PMI suggested, PMO can implement the project effectively at least at the third level. Korean companies which are about to introduce the PMO have to consider the PMO core functions and management level to increase the IS maturity.

According to literature review, fitness between IT activities and organizational strategy enhances performance. Theoretical research says that centralized company in IT activities is appropriate to cost-leadership strategy and decentralized company in IT activities is appropriate to differentiation strategy. But there are very few empirical research. The purpose of this study is to attest whether fitness between IT activities and organizational strategy enhances the information system performance. But the results of this field study were not consistent with literature that fitness of two independent variables enhance performance. So we should take other contingency variables such as organizational structure, culture etc. into consideration to investigate relationship between IT activities and strategy.

Although a significant number of studies have been conducted in user-based relevance criteria, a need for further research still remains. The rational is associated with the following inadequacies: (1) research on young user groups, (2) research on the Web environment with multimedia resources, (3) research on the irrelevance criteria and implications to improve related systems and services. Accordingly, this study identified user - based relevance and irrelevance criteria, examining 40 middle school third grader students who use KERIS Edunet site. The results identified 16 relevance criteria and 8 irrelevance criteria. Major implications related to information system and service improvements.

User can be offered various information form internet and reserve. However this operation is hard to be satisfied with user's requirement. Because it offer the alternative by self-mediation and the place where offer the information is distributed and a form or stored f[nm of data would be different. These cases occurred in change of enterprise recently. In a process of M&A, outsourcing or cooperation. necessity of new strategy become a pressing issue for ensuring interoperability on application, database of each enterprise and integration information management. Thus, interoperability of distributed data is a base condition for cooperation of legacy system, it will solve a problem such as available or clarity of data, problem of cooperation system. This paper use a XMDR for integration of distributed system and ensuring interoperability. By using XMDR, integrate a traveling information system and it will be solve the problem of interoperability and variety data problem that be occurred in integration of data by suggesting a technique of transaction management.

In this paper, a public key kanpsack cryptosystem algorithm is based on the security to a difficulty of polynomial factorization in computer communication is proposed. For the proposed public key kanpsack cryptosystem, a polynomial vector B(x,y,z) is formed by transform of superincreasing vector A, a polynomial f(x,y,z) is selected. Next then, the two polynomials B(x,y,z) and f(x,y,z) is decided on the public key. Therefore a public key knapsack cryptosystem is based on the security to a difficulty of factorization of a polynomial f(x,y,z)=0 with three variables. In this paper, a public key encryption algorithm for data security of computer network is proposed. This is based on the security to a difficulty of factorization. For the proposed public key encryption, the public key generation algorithm selects two polynomials f(x,y,z) and g(x,y,z). The propriety of the proposed public key cryptosystem algorithm is verified with the computer simulation.
