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.

윤명오,고재선,박형주,박성은 한국화재소방학회 2001 한국화재소방학회논문지 Vol.15 No.1

지하공동구는 최근 통신의 발달로 인해 국가 중추기능으로서의 주요 역할를 하는 시설로, 사고시 신속한 대처가 힘들고 케이블 연소시 발생하는 유독가스에 의한 검은 연기로 공동구 내에 진입하여 소화하기가 힘들다. 따라서 화재발생시 막대한 재산피해 및 통신의 두절 등 국가의 중추신경이 마비됨은 물론 시민 불편사항을 초래시켰다. 본 논문은 지금까지 발생되어온 공동구 화재를 바탕으로 실제 공동구 모형을 제작하여 화재를 재현함으로서, 과학적으로 화재의 성상을 분석하고 지하공동구 내에 소방설비를 갖춘 후에 일정온도에서 각각의 소방설비들이 제대로 작동하는지를 검증하는데 그 목적이 있다. 화재실험은 지하공동구 내에 정온식 감지선형 감지기, 방화문, 연결살수설비 및 환기설비를 설치하고 송 · 배전케이블은 일정구간 내화도료로 도장하며 난방관은 내화피복된 상태에서 실험하였다. 그 결과 최고 온도가 932℃로 측정되었고 일정온도에서 정온식 감지선형 감지기가 작동하여 화재위치를 정확히 수신반에 나타내었다. 그리고 송 · 배선케이블은 일정구간 내화도료로 도장한 것은 내화성능이 없는 것으로 나타났고, 내화피복된 난방관은 약 30분 정도의 내화 성능이 있는 것으로 나타났다. 컴퓨터 화재 시뮬레이션은 실제 화재 시험시의화재하중을 입력하여 실시한 결과 최고 온도가 943℃로 실제 화재시의 최고 온도인 932℃와 거의 일치하였다. 따라서 공동구 화재하중만으로 화재 시뮬레이션을 실시하여 화재의 성상에 대한 예측이 가능한 것으로 판단되며 시뮬레이션으로 얻는 열방출량, 연기층의 높이, 산소, 일산화탄소, 이산화탄소의 농도 등의 결과 값들을 실제 화재 실험시의 값으로 적용시킬 수 있는 것으로 판단된다. The utility tunnels are the important facility as a mainstay of country because of the latest communication developments. However, the utilities tunnel is difficult to deal with in case of a fire accident. When a cable burns, the black smoke containing poisonous gas will be produced. This black smoke goes into the tunnel, and makes it difficult to extinguish the fire, Therefore, when there was fire in the utility tunnel, the central nerves of the country had been paralyzed, such as property damage, communication interruption, in addition to inconvenience for people. This paper is based on the fire occurred in the utilities tunnel in the past, and reenacting the fire by making the real utilities tunnel model. The aim of this paper is the scientific analysis of the character image of the fire, and the verification of each fire protection system whether it works well after process of setting up a fire protection system in the utilities tunnel at a constant temperature. The fire experiment was equipped with the linear heat detector, the linear heat detector, the fire door, the connection water spray system and the ventilation system in the utilities tunnel. Fixed portion of an electric power supply cable was coated with a fire retardant coating, and a heating tube was covered with a fireproof. The result showed that the highest temperature was 932℃ and the liner heat detector was working at the constant temperature, and it pointed at the place of the fire on the receiving board, and Fixed portion of the electric power supply cable coated with the fire retardant coating did not work as the fireproof. The heating tube was covered with the fireproof had the function of the fireproof about 30 minutes.

본 논문은 생체 면역시스템의 자기와 비자기를 구분하여 인식하는 세포독성 T세포의 특징을 이용하여 컴퓨터에서 자기 파일과 비자기 파일을 구분할 수 있는 T세포를 모델링하였다. 모델링한 T세포는 MHC 인식부와 향원 인식부로 구성되며 각각의 인식부를 이용하여 비자기 파일에 적용시켜 자기-비자기 구분이 가능함을 컴퓨터 시뮬레이션을 통하여 입증하였다. Biological immune system distinguishes nonself from self-body and protects self intrusion such as virus, pathogenic bacteria. In this paper, we make a model of the T-cell of immune system to apply to computer immune system. The modeled T-cell possesses the ability to be able to distinguishes self files from random files in computer. The T-cell consists of MHC perception and antigen perception, and distinguishes self from non-self through matching file which we must test. We verify the effectiveness of the proposed method by applying self-nonself discrimination in a computer virus.

Cimetidine is a histamine H₂-receptor antagonist, used for the treatment of endoscopically or radiographically comfirmed duodenal ulcer. pathologic GI hypersecretory conditions. and active, benign and gastric ulcer. Simple method for determining cimetidine in human plasma has been developed and validated. The analytical procedure for cimetidine showed a linear relationship in the concentration ranges from 0.05 to 5 pg/ml. Coefficient of variance (CV, ° o) for intraday and interdav validation and relative error (RE. ° o) were less than ±150 o. Based on this analytical method. the bioequivalence of two cimetidine 400 mg tablets, reference (Tagamet 400 mg) and test drug (Sinil CIMETIDINE 400 mg) was evaluated according to the guidelines set by the Korea Food and Drug Administration (KFDA). Release of cimetidine from the tablets in vitro was tested using KP VIII Apparatus II with various dissolution media (pH 1.2. 4.0. 6.8 butter solutions and water). Twenty-four healthy volunteers. 21.38±1.86 years in age and 68.71±8.68 kg in bode weight, were divided into two groups and a randomized 2x2 cross-over study was performed. After oral administration of a tablet containing 400 mg of cimetidine. blood samples were taken at predetermined time intervals and concentrations of cimetidine in plasma were determined using HPLC equipped with UV detector. The dissolution profiles of the two tablet formulations were very similar at all dissolution media. In addition. pharmacokinetic parameters such as AUC, and C_(max) were calculated and ANOVA was employed for the statistical analysis of parameters. The results were revealed that the diterences in AUCf and Cma, between the two tablets were 4.17% and 0.97% respectively. At 90% confidence intervals. the differences in these parameters were also within ± 20° o. All of the above mentioned parameters have met the criteria of KFDA guidelines for bioequivalence, indicating that the test drug tablet (Sinil CIMETIDINE tablet) is bioequivalent to Tagamet 400 mg tablet.

We investigated that the effects of residential type on energy balance in college students. Total sixteen college students were participated in this study, all subjects were assigned one of three groups: either school attendee students group, self-governed living students group, dormitory students group. Routine physical activity level (for 5 days including three weekday and two weekend) and food intake were surveyed. For investigation of degree of physical activity, all subjects were requested to record on their physical movements as possible as detail should be obtained. To all subjects, five-day dietary log form was given, and used for examining of calorie intake from their routine diet. There was no statistical difference in energy intake and consumption in each. However energy consumption was significantly higher than energy uptake in school attendee students group. All other groups were shown a similar energy values between energy uptake and consumption. There were no significant differences in energy intake and consumption in any of experimental groups when comparisons were made between weekdays and weekend. As far as energy uptake was concerned it was no statistical difference in any of major nutrients among groups. In conclusion, partial imbalance was found between energy intake and uptake in school attendee groups. This may be due to their more active life style than other groups'. In future studies, better controlled study should be performed not only more subjects are recruited but also minor nutrients are included for examining of energy balance.
