In view of the lack of efficient coordination of interdependent task in the collaborative design system, the mechanisms for temporal and resource coordination problems are established based on Petri Nets, respectively. Both of the mechanisms are encapsulated and implemented in the coordination component so as to increase the flexibility and acceptability of the system. We model the CSCW system based on Petri Nets for simulation, analysis and optimization. A case study on the overhead traveling crane is given to demonstrate and validate our theory.

In this paper, we propose a new model, assembled ERP, to analyze the reason why the small and medium sized companies have a low ERP implementation rate and to solve this. As a result of our analysis, the high initial costs and time required for implementing ERP keep such companies from implementing it as they have relatively limited resources. The assembled ERP model, however, reduces the scale of ERP by developing the ERP for the unique business of each and connecting a few 3rd-Party applications as a module to make ERP for common work. Also it enables easier data utilization by drawing up an API list that connects the 3rd-Party applications to the developed ERP when the user lacks knowledge in the master data of the 3rd-Party applications. Therefore it lets the small and medium sized companies introduce the ERP more easily by reducing the costs for ERP implementation and user training.

For trying to frontal attack of new solution by fusion of technical tasks and conditions with it's solving methods of the essential tasks of marine resource development and environmental conservation in addition with elements of electronic high-technologies, the skimmer robot was proposed by using of oil spill disaster prevention and its disposal system with sequentially circular collection type of magnetic oil spill adsorbent powder and fabrics on the electronic barge robot for the scheme of sustainable development of environment-friendly technology. It was verified from the experiment of electronic barge robot demonstrator that the skimmer system of magnetic oil spill adsorbent powder and fabrics was very effective and useful technique to collect oil spill samples. At this point, the barge-based electronic remote control was very useful system operating easily on the marine fields to skim oil spill with dangerous toxic substances of crude oil and very harmful to human. Therefore, fusion technology proposed in this study combined with electronic and marine technology is the novel contributable technology for developing marine environmental conservation and environment-friendly disaster prevention, and also its management techniques.

학술정보의 핵심인 학술지에 대한 정보 요구가 점차 전자저널로 변화함에 따라 도서관은 컨소시엄을 구성하여 효율적으로 전자저널을 구축하고 활용하기 위해 노력하고 있다. 그러나 우리나라의 전자저널 컨소시엄은 참여 도서관이 활발한 역할을 하기보다 운영기관과 콘텐트 제공자가 주도하는 경향이 있다. 이에 따라 우리나라에서 가장 많은 도서관이 참여하고 있는 KESLI 컨소시엄을 대상으로, 참여도서관, 콘텐트 제공자, 그리고 컨소시엄 운영자와 같은 다양한 이해관계자 집단을 통해 그 쟁점사항을 파악해 보고자 한다.이 연구의 목적은 KESLI 이해관계자 집단의 기대와 요구를 표적집단면담을 통해 조사한 결과를 분석하여 KESLI 컨소시엄의 발전적인 운영 방안을 마련하는데 있다.

초$.$중등학교에서는 교육인적자원부 주관 하에 개발한 ERP시스템인 전국단위 교육행정정보시스템(National Education Information System： NEIS)을 활용하고 있다. 본 논문에서는 NEIS를 교육행정업무뿐만 아니라, 국가인적자원을 평생 관리하는 정보시스템으로도 활용할 수 있음을 보였다. 그동안의 초 중등학교 정보관리시스템은 현장 적합도와 사용자 편이성이 미흡하였다. 이와 같은 문제점을 해결하기 위해서는 시스템의 재구축 또는 개정작업이 필요하다. 개정과 보완의 한 방법으로, 전 국민의 건강정보를 학교와 의원에서 공동으로 활용할 수 있는 구체적인 예를 제시해 보고자 하였다. 이를 위해 NEIS의 학생건강기록부와 의사가 기록하는 전자의무기록부의 건강정보를 통합하여 평생관리 할 수 있는 방안을 모색하였다. 구체적으로는, 학교와 의원에서 공통으로 관리하여야할 건강정보들을 XML로 작성해 보았다. 여기에 수요자의 요구에 적합한 뷰를 제공하기 위하여 각기 다른 XSL 스타일시트를 적용하였다. 이 뷰를 이용하여 건강정보를 효율적으로 관리하고 활용할 수 있음을 알았다. 이에 건강정보관리 비효율성과 유관기관간 연계성 미흡을 해결하고, 국가인적자원을 평생관리 할 수 있는 가능성을 확인하였다.

This study tried to develop the theoretical backgrounds, explaining consumers energy consumption behavior and analyzed its effects. In other words, this study investigated the factors influencing the amount of electronic energy consumption. In this study, we used 678 questionnaires which were selected a quota sampling by living area who were above 20 years old and married. Summary of results of this study follows. First, attitude for energy saving was positively related with female, high school graduated large size of family members, elderly, and middle-class consumers. In addition, consumers' search for energy saving were appeared passively in young consumers under 30 years old, and the family with the highest household income. Consumers' purchasing energy-efficient products was presented in large size of family members, and young consumers. Second, consumers' environmental oriented behavior, action-directed behavior, healthseeking behavior were significantly related with energy saving behavior, and active information search for energy saving, but not with purchasing energy-efficient products and consuming behavior of electrical energy. Third, the quantity of electric energy consumption was affected by the size of family members, the living size of house related with high energy demand, the attitude for energy saving, and searching information for energy-saving.

To overcome the ecosystem-crisis of resource depletion and climate change, we should maintain and develop a 'Sustainability' of our society. 'After-market' is defined like this : any market where customers who buy one product or service are likely to buy a related follow-on product. This is related to a automotive, electric and electronic, and remanufacturing industry. 'After-market' will be helpful for reuse and recycling of resources aspects, cost and economic efficiency, low-carbon, climate protection, and new industries and job creation effects, To promote 'After-Market', we need to guarantee the quality of products. In this regard, we refer and introduce a new standard, for example, BS8887, PAS141 and ISO20245 etc. In order to promote 'After-Market', first of all, product quality assurance and safety must be demonstrated in the process of reuse. Second, many aspects of a device that protects the rights of consumers to be provided. And third, the related laws and standards should be reviewed. Finally, original manufacturer's awareness for environmental protection and resource conservation and government's institutional support are needed.

TMN Agent Platform은 망 요소의 운영상태와 자원들을 GDMO에 따라 관리객체(Managed Object : MO)로 모델링 하고, 자원들의 현재 상태를 유지하며, 관리자(Manager)로부터의 망 관리 기능 요구에 따라 조작된다. 그러므로, 에이전트의 성능향상은 전체적인 통신망 관리의 성능향상에 직접적인 영향을 미친다.본 논문에서는 TMN 에이전트의 기능요구 사항을 분석하고, 이를 토대로 성능향상을 위해 멀티스레드 기법을 사용하는 병렬 처리 구조의 TMN Agent Platform의 기능구조를 제시한다. 또한 에이전트와 다양한 자원들간의 효율적인 메시지전달을 위한 체계를 제시하며, 구현된 TMN Agent Platform의 성능을 분석한다.Abstract TMN Agent manages the operational status and real-resources of network elements, such as switching nodes and transmission systems. It performs the requested management functions from manager and maintains consistent status data of real-resource. The performance of agent system affects directly the performance of network management operation. If the agent is implemented by sequential processing scheme with single process, the agent processing can be delayed or blocked according to the status of real-resources. This problem can be solved by parallel and distributed processing scheme.To improve the processing performance of TMN Agent, we propose a TMN Agent Platform's functional architecture that is based on parallel processing with multi-tread and effective message transferring scheme between agent and various real-resource. We analyze the performance of the implemented TMN Agent Platform.
