The teaching plan is an important material for teaching and learning, and it goes through many hardships to make out it. Although these materials have been shared through web and referenced for making their teaching plan by other teachers, it has been little utilized yet in learning. In this paper, we proposed a strategy for utilizing the teaching plan as a useful material in learning and had developed the web-based system for managing and utilizing the teaching plan based on the strategy.

Ever-growing recreation, tourism and ecotourism worldwide have become a significant factor of resource degradation in many protected areas. Managers of these areas are increasingly challenged to implement policies, strategies and actions that would protect the resource base while providing quality visitor experience. One major issue in managing protected area visitations is that of carrying capacity, or the question of "how much use is too much\ulcorner". Scientific studies of visitor impacts, often known as recreation ecology, has generated a knowledge base that provides valuable input to the visitor carrying capacity management process adopted by the U.S. National Park Service. This paper aims at (a) providing an overview of recreation ecology research and its application in managing visitor carrying capacity, and (b) examining the relevance of recreation ecology to East Asian protected areas with special reference to the visitor capacity issue.ity issue.

Electronic socuments described in SGML DTD are effedtive to manage with the object-oriented database. To do that,first of all, a database design for SGML documents must be preceeded. In this paper, we suggest an object-oriented meta schema for managing SGML DTDs, which describes logical structures of electrinic socuments. We also propose a method a methof to manage electronic documents in object-oriented databases through the application database schema which is synamically create from the meta schema.

In America, there has been increased empasis on corporates social responsbility in connect with corporate governance. Modern statutes have been enacted expressly empowering corporations to make donations for the public welfare or for charitable, scientiffic, or educational purposes. the Securities and Exchange Commission in the 1970's stressed improvement in corporate accountability by changing the traditional corporate governance, with emphasis on independent directors, and disintrested overview. The Korean Commerce Code and the Securities Exchange Law have introduced the independent outside-director and the audit committee. This outside-directors and the audit committee should supervise the corporate management by the managing directors to make donations for the public welfare or for charitable, scientiffic, or educational purposes. Korean statutes include many problems that would lose effect of corporates social responsbility in management. In order to become effective the corporates social responsbility, it should be established newly a provision of corporates social responsbility. And the outside-directors should be independent of and supervise the managing directors, and make donations for the public welfare. And the shareholders' supervisement rights on the managment should be strengthen.

Risk assessment of a railway system should be periodically conducted managing a large amount of accumulating accident/incident data and scenarios, which generally requires enormous time and efforts. Therefore, special information management system is essential for railway risk assessment, where data needed for decisions on managing the railway safety could be promptly supported. In this study, we develop the framework of a railway risk assessment information management system (RAIMS). The RAIMS is composed of two main modules: 1) hazard data processing module; 2) and risk assessment module. Hazard data could be turned into risk information using these two modules. The RAIMS will be useful in finding hazard conditions, quantitatively assessing the risk, and providing pertinent risk measures, eventually serving to prevent railway accidents and reduce severities of railway accidents.

Risk assessment of a railway system should be periodically conducted managing a large amount of accumulating accident/incident data and scenarios, which generally requires enormous time and efforts. Therefore, special information management system is essential for railway risk assessment, where data needed for decisions on managing the railway safety could be promptly supported. The objective of this study is to develop a railway accident analysis program for risk assessment. The program is application running on the web which links railway accident analysts throughout the railway industry to a central database. Data entered, together with associated code tables. is stored on MS-SQL database. The program uses the concepts of accident, safety events, causes, related factors(vehicle, person, infrastructure, tool/equipment), recommendations to bring together the various elements of railway accidents. The program will be useful in finding hazard conditions, accident scenarios, quantitatively assessing the risk, and providing pertinent risk measures, eventually serving to prevent railway accidents and reduce severities of railway accidents.

The abuse of the internet creates the problem of ′Internet Addiction′ in the lives of college students. The purpose of this study is to investigate the characteristics and effects of ′Internet Addiction′ in college students. Data was gathered by in-depth interviews with 13 college students who use the internet addictively. The internet addictive group was divided into three subtypes:internet game addicts, personal relation addicts and majors in computer science. There were many characteristic differences among the internet addict subtypes in internet use, and psycho-social traits, such as self-efficacy, impulsiveness, and time management ability. The effects of "Internet Addiction" in the lives of college students were divided into five categories: emotional problems, physical problems, family relationship problems, friendship problems, and schoolwork problems. This study suggests some implications on developing programs for managing and schoolwork problems. This study suggests some implications on developing programs for managing and preventing "Internet Addiction."

MANET has an advantage that can build a network quickly and easily in difficult environment to build network. In particular, routing protocol that uses in existing mobile environment cannot be applied literally because it consists of only mobile node. Thus, routing protocol considering this characteristic is necessary. Malicious nodes do extensive damage to the whole network because each mobile node has to act as a router. In this paper, we propose technique that can detect accurately the suspected node which causes severely damage to the performance of the network. The proposed technique divides the whole network to zone of constant size and is performed simultaneously detection technique based zone and detection technique by collaboration between nodes. Detection based zone translates the information when member node finishes packet reception or transmission to master node managing zone and detects using this. The collaborative detection technique uses the information of zone table managing in master node which manages each zone. The proposed technique can reduce errors by performing detection which is a reflection of whole traffic of network.

In less favored areas, it is getting more difficult to manage Satoyama according to aging of rural residents and depopulation. Some support of urban residents are necessary for management of Satoyama. In this paper, the role of Satoyama management activities was clarified through the analysis of the feature of activities for managing Satoyama. The questionnaire and interview surveys were done in order to clarify the actual conditions for management of Satoyama and activities of urban residents who are participating in NPO in Hyogo Prefecture. The results of analysis are as follows. (1)The form of rural-urban exchange in Satoyama is different in each Satoyama. (2)The urban residents are contributing to the region very much on both sides of the manager and the visitor in Satoyama. (3)Many urban residents visit Satoyama for the purpose of enjoying the variety of nature and culture programs in rural area. (4)There are some urban residents who participate in activities for managing Satoyama even if Satoyama is far from their residence. So it is important for rural residents to arrange the condition that they can visit rural area without difficulty.
