In this paper, we purpose the integrated TMS to solve the problem of current systems. The current system resulted in inconvenience because customers and users must contact to each system, when they want to know the information about orders. In this research, we develope a system with which customers and users can confirm all of order information from one system. To solve this problem, the information brought from two systems is integrated by constructing integrated database.

This study suggests a safety management model for construction management (CM) suitable to domestic conditions so that inefficiency resulted from the operation of construction projects by public and private institutes according to different systems can be eliminated for the securing of systematic and efficient safety management. Based on the suggested safety management model, this study also develops a safety management information system that can efficiently and consistently manage and maintain a large quantity of information, and give necessary supports in a speedy way in the managing of construction projects.

New renewable energy information becomes one of the greatest issues all over the world because of serious environment problems and limited fossil resources. The new renewable energy source information system is treated seriously for efficient management and distribution as dealing with these energy problems. However, it is difficult to manage and utilize new renewable energy information because gathering and surveying information is progressed individually in each research field. Therefore this paper will establish ISP(Information Strategy Planning) and propose the basic management system based-on GIS to analyze new renewable energy such as solar energy, wind power, small hydro, biomass, geothermal etc. and build the integration management system. The proposed integration management system can provide spatial analysis using thematic map, data search, data import/export and interpolation about users' queries.

We consider a problem of intelligent Integration Information system for research ship, and propose a design as one effective solution of the problem. The goals of the proposed design and system are as follows: management of engine, management of ship, researcher's work, education, training, manage schedule of the project, and thus to manage the whole life cycle of the research ship project. These goals are basically to facilitate and implement innovation- and enhancement-related activities which intelligent Integration Information system is fundamentally pursuing.

This paper is to aimed to design a model of Korea defense information resource management structure from the viewpoint of system's approach, especially focusing on planning/programming procedures, organizational structure and business process re-engineering. The author analyzed current projects and plans on the field of Korea defense information systems, for finding what kinds of problems and why the problems occurred. The author concluded that many problems came from wrong approach of previous information resource management. Highlights of the proposed model are as follows: 1) Planning and programming structure must be considered as a major information resources and it must be managed as a key role through the whole system life cycle; 2) Organizational structure should be properly set up for managing and implementing information system projects; 3) Business process should also be analyzed thoroughly for re-engineering and innovating current inefficient organizational structure. These three additional viewpoints added to previous model for improving Korea defense information resource management.

As "Nationwide Educational Information System", as one of 11 essential tasks of the electronic government, is to be introduced step by step from March in 2003, the current School Information Management System servers in each school cannot be functioned appropriately any more. Management of school cumulative records will be done by the integrated server of the regional Office of Education. Accordingly, more than 20,000 servers of various kinds available in each school should be put into use in one way or another. So this thesis aims to suggest how to reuse these servers in schools, and how to approach modeling of the 21st-century school in the School Information Management System.

In this paper, we present an integrated management system for WSNs (Wireless Sensor Networks). Each sink node of heterogeneous sensor networks is connected with a gateway. By supporting various hardware platforms and networking models, the gateway is able to collect management information from one or more WSNs and store it in a MIB (Management Information Base). The management system obtains management information from the MIB of the gateway by SNMP (Simple Network Management Protocol) and analyzes it. A manager can have access to the management system through the Web wherever the Internet is available and manage WSNs as well as sensor nodes. We implemented the proposed management system and our findings revealed the practicality of this system.

To manage a cluster of distributed server systems, a number of management aspects should be considered in terms of configuration management, fault management, performance management, and user management. System performance monitoring and reporting take an important role for performance and fault management. In this paper, we present distributed system architecture modeling of a performance monitoring and reporting tool. Modeling architecture of four subsystems are introduced: node agent, data collection, performance management & report, and DB schema. The performance-related information collected from distributed servers are categorized into performance counters, event data for system status changes, service quality, and system configuration data. In order to analyze those performance information, we use a number of ways to evaluate data corelation. By using some results from a real site of a company and from simulation of artificial workload, we show the example of performance collection and analysis. Since our report tool detects system fault or node component failure and analyzes performances through resource usage and service quality, we are able to provide information for server load balancing, in short term view, and the cause of system faults and decision for system scale-out and scale-up, in long term view.

In this paper, we propose a web GPS based logistics vehicle control management system using MVC design patterns. The proposed system is designed by applying design patterns of object oriented modeling called mini-architecture to enhance reliability of software as well as promote stability of overall system design. In addition, we can get a position information by means of the GPS embedded in PDA and communicate between client and monitoring server using CDMA network so that the position of client can be identified directly by the map service. The system provides an moving object indexing technique which extends the existing TB-tree to manage and retrieve a transporting trajectory of logistics efficiently. Finally, with development of the logistics vehicle control service called WG-LOGICS system, we can verify the usefulness of our system which is able for monitoring a vehicle preparation, allocating registration, loading a burden, transfer path, and destination arrival in real world.

This study examined the predictive power of data mining algorithms by comparing the performance of logistic regression and decision tree algorithm, called CHAID (Chi-squared Automatic Interaction Detection), On the contrary to the previous studies, decision tree performed better than logistic regression. We have also developed a CDSS (Clinical Decision Support System) with three modules (doctor, nurse, and patient) based on data warehouse architecture. Data warehouse collects and integrates relevant information from various databases from hospital information system (HIS ). This system can help improve decision making capability of doctors and improve accessibility of educational material for patients.
