Using transportations like railway, aviations and roads has been increasing continuously. Traffic accidents have been increasing as well. To prevent or lessen these accidents become a big issue to solve. Therefore, more enforced safety levels are being required to meet. In railway field, continuous efforts of railway safety are being executed to prevent traffic accidents. In present, a railway accident has been decreasing since subway accident happened in Daegu Subway in 2003. However, safety levels in railway field have not yet achieved as much as in advanced countries. Basic concept for enforced safety level in railway system is to prevent or minimize accidents by managing systems like related facilities, management method, organization, education. This is the same concept to minimize error rate in six sigma theory. In this paper, we are to apply six sigma techniques used in manufacturing industry to railway safety and go through ways to make more efficient railway safety system.

Role Based Access Control (RBAC), which is a method, using role as an access control, has been popular with users and it is recognized as an effective method to replace the Discretionary Access Control and the Mandatory Access Control However, the existing Role Based Access Control Models have only been limited to the bureaucracy organization in which a distinctive hierarchy system was used, incorporating a stable structure and a standardized work system. Only in some parts, some access control models have been used, which supports 'Team' concept, such as Team Based Access Control Model. However, it did not incorporate the characteristics of the adhocracy organization, which is similar to the company's task force team, whose characteristics are organic, temporary, no standardized operation procedures, and many frequent changes. In this study, we have discussed the characteristics of the adhocracy organization which is different from the existing bureaucracy organization, and we have also discussed the problems related to when the existing access control models are used as the access control model for the adhocracy organization due to its characteristics. In addition, based on the problems, we have suggested an improved role based access control model for the adhocracy organization, and have come up with the solutions when any problems occur in the access control system.

The national framework data is being constructed by the second plan of NGIS(National geographic information system). However, themes of national framework data are not reflecting various geographic information of marine that demand is increasing. Also, it is mean that national framework data did not consider concept of country which is integrate land and marine. Therefor, this study perform to organize marine framework data through analysis of overseas framework data, and present the composition of national framework data that land and marine are integrated through investigate relationship between national framework data and marine framework data.

This paper suggests a model of Living & Learning Nation as a new ploicy framework. It is a combination of Living Nation and Learning Nation. Living Nation model takes the nation as a living entity composed of spirit, resource, and communication : it grows but healthy and balanced growth is needed, its organs are closely connected, it has a circulation system, the 'spirit' factor plays the central role, etc.. Learning Nation model is a national level version of learning organization concept. The model defines new perspectives on the objectives, span of means, and the role of government in S&T policy. Therefore, the model can be used to give new insights to policymakers of developing countries facing the knowledge-based economy.

In earth moving construction equipment used for rough and dangerous works, seat suspension system is the only means for reducing the vibration transmitted to the operator. Thus ISO(International Organization for Standardization) 7096 suggests a recommendation for the vibration characteristics of the seat suspension system in order to protect the human beings from excessive vibrationl. In this research, a new mechanical type seat suspension system is designed and a mathematical model, effective design parameters of the seat suspension system are determined and concept design strategy is presented.

Document management system is a tool, based on the document life cycle concept, for structured management of various documents within an organization. In this paper, we address a development process of document management system based on SGML. We have developed a document management system which can support a variety of types in documents such as informal data, HTML, CGI and so on. Using the developed system, users can access documents in the system through an internet browser, and also add or modify existing documents.

Recently, The concept of strategic groups is recognized as a basic unit of understanding framework in strategic management research. Researchers have consistently approached the relationship between strategic groups and organizational variables(organization structure vs strategies, management process vs strategies, management systems vs strategies, environment vs strategies, strategies vs performance). However the relationship between strategic groups and human resources has been neglected in theortical approach and empirical approach. Therefore this study explores the relationship between strategic groups and human resources management.

In this paper it was attempted to design a system for the effective development of electronics industry by use of systems management concept. For the design of this system, current status of electronics industry was analyzed; problem area was derived through this analysis and developmental strategy was determined. As an organization for centeralized coordination, "Electronics Industry Committee" was proposed. The committee controls three specialized organizations such as R&D center, marketing management center, and council for political support. Each function of these special organizations was introduced and special role as a system manager was described.

In this paper, we discuss the concept of Spatio-Temporal Data Warehouse and analyze the organization model of spatio-temporal data. Based on the above, we found the framework of Spatio-Temporal Data Warehouse composed of data source, processing tools and application, which covers the whole process from building warehouse to supplying services.

Medical Subject Headings (MeSH), a medical thesaurus created by the National Library of Medicine (NLM), is a useful resource for natural language processing (NLP). In this article, the current status of the Japanese version of Medical Subject Headings (MeSH) is reviewed. Online investigation found that Japanese-English dictionaries, which assign MeSH information to applicable terms, but use them for NLP, were found to be difficult to access, due to license restrictions. Here, we investigate an open-source Japanese-English glossary as an alternative method for assigning MeSH IDs to Japanese terms, to obtain preliminary data for NLP proof-of-concept.
