탄소분말이 물리적으로 코팅된 리튬 음전극의 충방전 특성

To improve the safety and electrode characteristics of lithium metal anode, physically coated electrodes on lithium metal surface by three kinds of carbon are prepared and their charge- discharge performances are investigated by adopting the C-Li electrodes as the anode of rechargeable lithium batteries. The lithium anode coated by the carbon powder with smaller particle size and higher surface area, which has higher packing density and lower surface roughness, shows better performance in charge-discharge characteristics. The carbon coating on lithium surface can be more effective in small-sized cells.

In this paper we present a knowledge-based SMD fault diagnose system in which the case-based reasoning and hybrid neuro-fuzzy technology are applied This knowledge-based system can be used as a sub-system of enterprise knowledge management system (KMS). A machine fault diagnose operation is stored as a case with problem indices and solution indices to the case-base and those indices are also used as learning data for hybrid neuro-fuzzy system. The proposed knowledge-based fault diagnose system provides the stable and consistent maintenance plan by removing the subjectivity of human expert.

Necrobiosis Lipoidica is a skin disorder of unknown cause, which shows characteristic clinical and histological findings. With histochemical studies, we report of a case which oecurred on the both pretibial surfaces in a 5]-year-old female. Having had treatment with aspirin and dipyridarnole for 9 months. The results were successful.

The idiopathic calcinosis of the scrotum which was first described by Shapiro et al. in 1970 is usually multiple, asymptomatic nodules of the scrotal skin and is easily misdiagnosed clinically as calcified epidermal inclusion cyst or pilar cyst. We present three cases of the idiopathic calcinosis of the scrotum. Clinically these three patients showed slightly yellowish papules or nodules in the scrotum without any other cutaneous disorders and subjective symptoms except mild itching sensation in one case. Histopathologically calcium deposits were found in the dermis without any evidence of residual cysts, and partial foreign body reaction was seen around the calcified area in one case. Laboratory findings including serum calcium, phosphorous and potassium level were within normal limits.

기업의 생산 및 서비스 영역에서 설비의 의존도가 심화되고 있다. 이에 따라 설비를 효율적으로 관리하기 위한 설비관리 업무의 중요도도 증가하고 있다. 효과적인 설비관리 업무는 설비의 수명을 연장시키고 설비운영 효율을 증가시킨다. 체계적인 성과평가시스템은 작업자의 업무의욕을 증대시켜 설비관리 업무의 수준을 높일 수 있다. 설비관리 업무의 성과평가를 위한 다양한 연구가 이루어져 왔으나 전략을 중심으로 한 체계적인 성과평가 연구는 다소 부족한 상황이다. BSC는 비전을 달성하기 위한 전략을 중심으로 균형있고 체계적인 성과평가 방법으로 많이 활용되고 있다. 이에 본 연구에서는 BSC 개념을 적용하여 설비관리 업무에 대한 성과평가시스템을 개발하였다. A company's reliance on plants is growing in the area of production and service. Therefore, the importance of the work on plants in order to manage them efficiently is growing. Effective plant management increases the durability and efficiency of the plant. An organized BSC also increases the workers' will to work harder which is to bring the higher quality of plant management. In this way, however, it has studied with variety ways to assess plant management task for performance evaluation, there is a little deficiency that the study of methodical performance evaluation that based on the some strategies. The BSC, the very way, and it has been utilized in balanced and methodical performance evaluation means in widespread fields with strategy as the center to get visions. In this study, I have developed the performance evaluation system for plant management, appling BSC concept.
