In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

김남재,김진희,이경태,서광식,정현용,이승민,김석현,이병석,이헌영 대한소화기내시경학회 1999 Clinical Endoscopy Vol.19 No.3

A carcinoid tumor of the stomach is uncommon, has no clinical symptoms, and is regarded as a benign. It is also incidentally found in most cases. 48-year-old woman with gastric carcinoid tumor was admitted. She had suffered from a anorexia and a dry mouth for 4-months. A gastroscopy revealed a polypoid mass on the greater curvature of the mid-body of the stomach which was subsequently thought to be an adenocarcinoma. An endoscopic mucosectomy revealed however, that it was a carcinoid tumor. A case of carcinoid tumor of the stomach is here by presented with a brief literature review.

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

This study proposes a new analytical method for assessing outage cost of composite power system with considering transmission system. Uncertainty of outages of generation system and transmission can be included. Composite power system ELDC(CMELDC) on HLII is developed and proposed newly from reliability evaluation of composite power system in order to analysis the outage cost on HLII. Equivalent outage cost of transmission system(EOCTS) is proposed newly in this study too. This means the outage cost conversed from unarrival which is power occurred by the outage of transmission system. The effectiveness of the proposed approach is demonstrated by the two case studies. The results show that this approach can evaluate the equivalent price of the outages of transmission lines.

석창욱,양승준,곽병철,이재응 중앙대학교 기술과학연구소 2000 기술과학연구소 논문집 Vol.30 No.-

기존 접촉식 베어링과 비교할 때 능동 자기 베어링(AMB)는 많은 장점을 가진다. 자기 베어링 시스템은 주축을 자기력을 이용하여 부상시켜 기계적인 마찰이 없는 상태에서 회전시키기 때문에 윤활을 하지않고도 작동시킬 수 있다. 따라서 이 베어링은 우주에서의 진공상태와 같은 극한상황에서도 사용할 수 있다. 특히 원추형 자기 베어링은 4조의 전자석으로 구성되어 래디얼 타입 자기 베어링보다 소형, 경량화할 수 있는 장점을 가진다. 본 논문에서는 먼저 원추형 자기베어링에 대한 운동방정식을 유도하고, 이 시스템의 진동 제어를 위해 비연성인 디지털 PD, PID 제어기를 설계하였다. 컴퓨터 모의실험을 통해 제어기의 성능을 평가하여 만족할 만한 성능을 얻었다. There are many advantages of the Active Magnetic Bearing(AMB) system, compared with conventional contacting bearing systems. Since the spindle in the AMB system is levitated by electro-magnetic forces and rotates without mechanical friction, it can run without lubrication. So, it can run in the extreme circumstances, e.g. a vacuum condition in the space. Particularly, the cone-type AMB system consists of only 4 couples of magnet, it can be smaller and lighter than radial-type AMB system. In this thesis, the equations of motion of the cone-type AMB system is derived first, and the digital PD and PID controllers are designed for the vibration control of the system. The controllers are designed based on the decoupled equations of motion, and the performance of the controllers are evaluated through the computer simulations. The results of the simulation show good performance of the controllers.
