The maintenance prices in information security industry between Korean companies and foreign companies have been a big difference. Korea Information Security SW maintenance standards were not adequate for the rate, and there was disagreement between domestic companies and governments. This research, therefore, surveyed a standard of information SW and the status of maintenance payment rates. The study suggests an estimation method and verifies the method and an appropriate maintenance cost rate. According to the results of the study, the current maintenance cost should be increased or decreased independent with a kind of information security systems. Based on the study, Korea government is able to change the maintenance policy in information security. And the domestic companies get a theoretical ground for improving the rates of maintenance costs in information security systems and are able to allot the resources effectively.

By the time the interest on the u-City is continuously growing as a test bed for verifying the potentials of ubiquitous convergence industries, research on the u-Safety gradually increases as well, as a typical service and application area of u-City. Like the other service areas of u-City, in order to provide u-Safety services smoothly, it is crucial to integrally connect u-City services and infrastructures that have operated under distributed environment. In this study, we suggest an approach for design of u-Safety service and monitoring architecture by combing CIM/WBEM standard with GMA. CIM/WBEM and GMA are broadly applied in the distributed resource monitoring environment and are widely recognized as data acquisition architecture under massive monitoring data volumes respectively. Considering the growing research needs for standardization and extension of u-City service infrastructure, it is expected that our integrated infrastructure model will be used as a reference model for effective integration of distributed resources with newly added services.

Existing application systems of enterprises can process and collect a lot of information within enterprises, but it could be difficult to share validated information with partners and other system in the process of contacting to other legacy systems required in cooperation environment. For solving these problems, EAI systems are introduced in cooperation environment so that data sharing and integration can be achieved. The integration based on EAI is not limited to particular business system but all systems of an enterprise so that standard of suitable metadata level is needed for forwarding consistently between each business of systems. Therefore this paper maintains consistency of data sharing and integrating among legacy systems in cooperative environment for proposing message exchanging based on bridge XMDR.

Because the current disaster management task is being processed by using a separated operation system and an insufficient information system by each division, construction facilities suffer great damage by disaster. This research has classified the disaster management business phase and information by each phase through analyzing the existing disaster management information and business process. Then, it has built a disaster management information breakdown structure for integrating of individual disaster information, and also established a standard XML (eXtensible Markup Language) schema of disaster management electronic documents for a real-time utilization. The suggested methods in this research are verified by developing a manual system of electronic type. The disaster management IETM developed in this study provides the consistency for processing the disaster management tasks and the prevention of information omission. And it can be used as a electronic decision making tool for providing of integrated disaster management information.

This study aimed to design a knee brace with dry electrode EMS (Electrical Muscle Stimulation) for elite badminton players suffering from knee pain and assess its effectiveness in relieving pain and improving mobility. The assessment measured knee joint range of motion (ROM), Sargent jump height, and pain perception using a visual analog scale (VAS). Four experimental groups were established: stability, pain induction after 100 squats, muscle soreness induction with a regular knee brace, and muscle soreness induction with the EMS knee brace. The most suitable knee brace was selected from four samples to design the EMS knee brace. The conductive fabric was integrated into the inner surface of the knee brace to enhance EMS conductivity for the quadriceps muscles. Tensile strength tests showed that the dry electrode did not significantly affect the physical functionality of the knee brace.Regarding knee joint ROM and Sargent jump height, the EMS knee brace outperformed muscle soreness induction with a regular knee brace and wearing a standard knee brace. VAS measurements demonstrated that the EMS braces effectively alleviated pain perception in most cases. The results indicate the potential for developing EMS braces to alleviate pain and prevent injuries for athletes across various sports.

This paper presents a Train Communication Network simulator (TCNS) that can be used to evaluate the performance of TCN. TCN was accepted as the standard of the protocol for the communication network in trains. We carry out some simulation tests using the TCNS to show practical uses of the simulator. Results of some simulation tests are also reported

The paper describes the implementation of the video conferencing system using public key infrastructure which is used for user authentication and media stream encryption. Using public key infrastructure, we are able to reinforce the authentication for conference participant and block several malicious hacking while protecting conference control information. The paper shows the implementation of the transportation layer secure protocol in conformity with Korea public key authentication algorithm standard and symmetric key encryption algorithm (RC2, SEED, DES and 3DES) for media stream encryption. The feature of the paper is transportation layer secure protocol that is implemented for protection of information on a user authentication and video conference and the media streaming encryption algorithm also can be envisioned with another block encryption algorithm. The key for media streaming encryption may be safely distributed by the transportation layer secure protocol.

In this paper, we propose a reference model for logistics processes to improve the effect of RosettaNet standards application to domestic industry. First of all, implementation cases applied to logistics processes in the world are investigated. Second, logistics processes of domestic manufacturers are analyzed for the application of RosettaNet standards, and the processes are compared with PIP. Finally, a new logistics processes model and corresponding PIP documents which reflect domestic situations are proposed.

Artificial Neural Networks(ANN) have been successfully applied to various kinds of business and engineering problems, especially those involved in pattern classification. However, because of the lack of design standard or guidelines, the structure of specific ANN depends on the designer's own experiments or choices. In other words, even though we could construct a better ANN, we often steeled down with just a satisfactory ANN. The purpose of this research is to apply the Genetic Algorithm(GA) to design a structure of ANN that yields better performance compared to the existing test results. For a bankruptcy prediction problem. an exiting research using ANN which consists of 22 input processing elements(PEs) for financial ratios and 5 hidden PEs showed 70% hit ratio. In our research, the input financial ratios and the number of hidden PEs are determined by GA. The best ANN, which consists of 8 input PEs and 6 hidden PEs, shows 78.03% hit ratio. In addition, we compare the performance of two types of reproduction schemes, i.e., generational reproduction and steady-state reproduction.

기업 환경이 글로벌화 됨에 따라 다수의 기업들이 하나의 공동 프로젝트를 수행 하기 위해 인터넷 등의 통신 네트웍을 통해 기업 간 데이터 등을 교환 및 공유하여 하나의 기업이 업무를 수행하는 것과 같은 유기적인 비즈니스 프로세스를 지원하는 가상 협업(Collaboration) 환경의 중요성이 날로 강조되고 있으며, 이러한 환경을 가상 기업(Virtual Enterprise)이라 한다. CALS는 가상 기업을 구축하기 위한 핵심 기술로써 이질 분산 데이터의 공유 환경을 제공하기 위한 여러 형태의 요소 기술들을 정의하고 있다. 본 논문에서는 여러 기업들 사이에서 데이터를 공유하기 위한 기반 기술인 CALS 표준 데이터 공유 서버에 대해 살펴본다. 특히, CALS 환경에서 주목하고 있는 SGML, STEP 등의 표준 데이터를 공유하기 위해 필요한 분산 객체 기반 서버 컴포넌트에 대해 논한다. 마지막으로 CALS 표준 데이터 공유 서버를 응용하여 기업간의 문서 공유 시스템을 개발하여 본 시스템의 유효성을 검증한다.
