The need and concern about ecosystem are growing rapidly. However, ecosystem management systems are still in the first stage since the data are handled locally and separately. It results in the waste of money and time. In this research, we designed and implemented ecosystem management system of stream region using geographical information system(GIS) that is able to be used to manage the natural resource efficiently. It is expected to be used as a useful tool for Improvement of environment and management of ecosystem as well as recovery of natural environment.

Most organization are using E-mail(electronic mail) currently, but we seldom see the organizational success from the E-mail utilization strategically. There are many research which are focusing on the selection and usage of E-mail as a electronic communication media based on Information Richness Theory and Critical Social Theory. The purpose of this study is to investigate the effects by using E-mail through providing the model of perceived impacts. This model considers the moderate factors such as top management supports, organizational usage, and organizational pressure based on CST. Also it provides the guideline how to use E-mail strategically.

This paper presents a statistical process control(SPC) system in the electronic parts manufacturing process. In this system, an SPC method is integrated into the automated inspection technology on a real time base. It shows how the collected data can be analyzed with the SPC to provide process information. also presented are stuided of subpixel image processing technology to improve the accuracy of parts mearements , and the cumulative-sum(CUSUM) control chart for fraction defectives.An application of the developed system to connector manufacturing process as a part of computer integrated manufacturing (CIM) is presented.

This study examined the individual investors' Behavior and proposed the research task how significant difference within and among investor's personality types. First of all, we investigated factors that influence individual investor's investment behavior, such as, openness, will to achieve, self-monitoring. As result investors who have lately five number of holding stock are more dependent on openness and will to achieve.

A huge amount of financial information in large databases makes performance comparisons among organizations difficult or at least very time-consuming. This paper investigates whether neural networks in the form of self-organizing maps can be effectively employed to perform a competitive benchmarking in large databases. By using self-organizing maps, we expect to overcome problems associated with finding appropriate underlying distributions and functional forms of underlying data. The method also offers a way of visualizing the results. The database in this study consists of annual financial reports of 100 biggest Korean companies over the years 1998, 1999, and 2000.

This study deals with the concept of Microcomputer Playfulness(MCP), Even though MCP was introduced recently in the MIS research, the concept is expected and empirically supported to be significant in explaining information technology adoption and usage. Based on the Technology Acceptance Model(TAM), this study presented a revised model to explain individual PC use and explored the role of MCP in PC use. The results showed that MCP has a direct influence on PC use rather than a mediator between Self-efficacy and PC use, and that MCP is a better predictor of PC use than Computer Anxiety.

Today, satellite remote sensing and geographic information systems plays an important role as a advanced science and technology, and becomes a superpower tool of the study and research in various fields of Earth Science. This study reviews the application of satellite remote sensing and geographic information systems for many specialists in the fields of the fishery and ocean science. In future, satellite remote sensing and geographic information systems will be greatly used to observed, monitor and predict various phenomena associated with the fisheries and oceans, in order to seek safety in a natural disaster, and menage and conserve the fisheries and resources and the oceanic environments.
