With the rapid and broad changes of information media and information environment the traditional libraries have been evolving into the digital libraries. An analysis for the Planning and realization of the electronic resource management system was carried out to establish the various electronic resources in the digital library, the first in Korea. The study targeted from electronic journals, web-based databases, e-books, and to open access resources. The focus of the analysis lies in the Providing practical integrated electronic resource management for digital librarian based on the framework of effective Electronic Resource Management Initiative(ERMI) of Digital Library Federation(DLF) with network and electronic resource description. The analyses included life-cycle, subscription models, coverages. types of information provider for electronic resources. and system organization for implementation of electronic resource management system.

컴퓨터 시뮬레이션이라는 개념이 세상에 소개되고 널리 사용된 것은 이미 오랜 전의 일이다. 또한 이러한 방법론이 여러 방면으로 제조/생산 분야 기업의 이윤을 증대시키는 데 기여할 수 있다고 알려져 있고 실제로 일부 영역에서는 기여를 하고 있다. 하지만, 냉정하게 현실을 판단해보면 컴퓨터 시뮬레이션이 좀 더 넓은 제조 영역에서 그 자체의 가치를 향상시키기 위해서는 아직 부족한 점이 존재한다. 예를 들어, 적용하고자 하는 분야에서 컴퓨터 시뮬레이션의 효용 가치를 발견하지 못한다거나, 시뮬레이션 모델링 업무 자체가 하나의 새로운 부담으로 다가오는 일, 또는 기업의 입장에서 시뮬레이션 소프트웨어의 가격이 너무 높기 때문에 컴퓨터 시뮬레이션을 도입하고 싶어도 비용적인 측면에서 벽에 부딪치는 일이 빈번하게 발생을 하고 있다. 본 논문에서는 이러한 문제점들을 해결할 수 있는 방법론들에 대한 분석 및 사례들을 보이고자 한다. 컴퓨터 시뮬레이션 모델링을 기존의 라이브러리를 활용하여 좀 더 쉬운 방법으로 재활용 할 수 있는 방법론, 제조 현장 어디서나 컴퓨터 시뮬레이터에 접속하여 시뮬레이션을 수행 할 수 있는 방법론 그리고, 이러한 방법론들이 실제로 기업의 업무에서 어떠한 기여를 할 수 있는지에 대한 분석을 수행하고자 한다.

As wireless and mobile technologies have advanced significantly, lots of large sized healthcare organizations have implemented so called mobile hospital (m-Hospital) which provides a location independent and point of care (POC) clinical environment. Implementation of m-Hospital enhances quality of care because health professionals such as physicians and nurses can use hospital information systems at the very place where patients are located without any delay. This paper presents a real-time patient monitoring system based on wireless network technologies. A general framework for the patient monitoring process is introduced and the architecture and components of the proposed monitoring system is described. The system collects and analyzes biometric signals of in-patients who suffer from cancer. Specifically, it continuously monitors oxygen saturation of patients in bed and alarms health professionals instantly when an abnormal status of the patient is detected. The monitoring system has been used and clinically verified in a university hospital.

Recently, there has been an increase in the demand to enhance the intelligence of construction equipment and systems. Especially for semiautonomous and autonomous systems that have great potential for impact on the construction industry, artificial intelligence approaches are required to generate instructions and plans necessary to perform tasks in dynamically changing environments on their own. The framework for an intelligent earthwork system (IES) is suggested in this paper. It generates a plan automatically for construction equipment and provides a means of cooperation between construction equipment seamlessly. This paper describes the system architecture, control strategy, task planning method, and resource allocation method for IES.

ERP(Enterprise Resource Planning) 시스템은 급여, 회계, 인사, 생산, 판매, 물류 등을 포함한 핵심 비즈니스 프로세스를 담고 있는 소프트웨어이다. 인터넷의 등장으로 ERP 시스템이 WEB 기반으로 전환되었고 ERP의 영역도 기업내부에 국한된 것이 아니라 기업간의 거래를 모두 포함하기에 이르렀다. 그러나 ERP 시스템은 회사의 중요한 의사결정 데이터들과 한 Application 안에서 일어나는 Transaction 처리 등의 정보 보안에 대한 취약성을 가지고 있다. 이에 ERP 시스템에도 보안에 대한 필요성이 대두되었으나 ERP 업체들의 대다수는 아직도 구체적인 보안에 대한 방안을 제시하지 않고 있는 실정이다. 결국 비즈니스의 성공도 취약한 기업의 자원을 인증되지 않은 다른 사용자로부터 보호하는 능력에 달려 있으며, 이 연구의 목적은 ERP 시스템의 보안 이슈를 어떻게 다룰 것이며, ERP 보안 요구 사항을 어떻게 모델링 할 것인가에 대한 연구 이다. 현재 나와있는 SAP R/3와 EAGLE ERP의 제품 보안 모델을 비교함으로써 외산 제품과 국산 제품의 보안 요구 사항을 분석 하고, ERP시스템 보안에 대한 고려사항 및 접근 방법을 모델링 할 것이다. 본 연구에서는 UML을 이용하여 ERP 시스템 안에서 찾을 수 있는 모든 보안 사항을 점검 하고,UML의 물리적 요소와 논리적 요소를 이용함으로써 ERP 보안을 모델링 하고자 한다. 이 논문을 통하여 ERP 시스템의 각 분야의 담당자가 ERP 보안을 개념적으로 접근 할 수 있도록 할 것이다. 차후 연구 과제는 좀더 구체적인 모델링을 통한 ERP 보안 solution 개발이다.

Purpose: This study was conducted to investigate the school related stress and the need of mental health education among adolescents. Method: The subjects were selected by convenient sampling comprising of 1,049 high school students. The instrument of the study was the modified School Stress Scale by Kim (2002) and the Scale of Mental Health Education Need developed by Hyun et al. (2005). Results: School-related stress and the need of mental health education were higher in female students than male ones. Among the types of stress, stress related to academic activities was highest for all students. The need of stress management was highest, which was followed by the need of self-management. As for the need of mental health education and school-related stress according to general characteristics, the need was significantly different according to the Sender, grade, and experience in mental health education, and school-related stress was significantly different according to gender and grade. Conclusion: This study revealed that there was a correlation between school-related stress and the need of mental health education in high school students. This study also suggested the basic information and framework for planning, developing, and providing the school based mental health promotion education for the high school students.

To ensure that equipment outages do not directly impact the reliability of the ISO-controlled grid, market participants request permission and receive approval for planned outages from the independent system operator (ISO) in competitive electricity markets. In the face of major generation outages, the ISO will make a critical decision as regards the scheduling of the essential maintenance for myriads of generating units over a fixed planning horizon in accordance with security and adequacy assessments. Mainly, we are concerned with a fundamental framework for ISO's maintenance coordination in order to determine precedence of conflicting outages. Simulated annealing, a powerful, general-purpose optimization methodology suitable for real combinatorial search problems, is used. Generally, the ISO will put forward its best effort to adjust individual generator maintenance schedules according to the time preferences of each power generator (GENCO) by taking advantage of several factors such as installed capacity and relative weightings assigned to the GENCOs. Thus, computer testing on a four-GENCO model is conducted to demonstrate the effectiveness of the proposed method and the applicability of the solution scheme to large-scale maintenance scheduling coordination problems.

Recently, an ERP (Enterprise resource Planning) system has been becoming an essential S/W tool for companies to manage their business processes and manufacturing resources. As the information exchange becomes more complex, not only corporate companies but also small- and mid- sized enterprises (SMEs) are required to build an ERP system. However, for small- and middle- sized companies, the adoption of ERP systems becomes challenging due to high cost and long installation time of the system. This paper presents a novel concept of an adaptive ERP system incorporating the ontology structure of the business supply chain information. The proposed ERP installation methodology is illustrated with an example of a door-trim manufacturing company in the automotive supply chain.

Since various R&D projects about technology convergence was conducted by the government of Korea, the lack of liaisons among the projects has been accepted as serious issues related on the duplicated funding. In this article, we propose a research framework to analyze the relationship among national R&D projects about technology convergence. In detail, the projects have been sorted and categorized with the data collected from National Science and Technology Information Service (NTIS) in order to analyze the current state of national R&D projects. The linkages among projects are then established using the results of analysis on national R&D projects. Finally, the relationship maps have been developed. It is expected that the result could be applied to identify the relations among projects and handle problems on the duplicated funding.
