Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

The expression of pro-apoptotic molecules, p53 and Bax, in the spinal cord of rats with experimental autoimmune encephalomyelitis (EAE) was examined. Apoptosis was confirmed by the terminal deoxynucleotidyl transferasemediated dUTP nick end-labeling (TUNEL) method. TUSEL (+) apoptotic cells were mainly either ED1 (+) macrophages or T-cells in the parenchyma of E N . Western blot analysis showed that both p53 and Bax expression significantly ( p < 0.01) increased in the spinal cords of EAE rats at the peak stage, and thereafter declined. An immunohistochemical study showed that inflammatory cells (notably T cells) in the parenchyma express p53 and Bax, while brain cells, includng neurons and glia, were devoid of these nuclear staining of these molecules. The nuclear expression of p53 largely matches apoptotic cells in the parenchyma of EAE. These finchngs suggest that pro-apoptotic molecules, p53 and Bax, may play an important role in eliminating T cells in the parenchyma in EAE.

This paper achieves a research about avoidance of obstacles avoidance based on ultrasonic sensor. The performance of the proposed obstacle avoidance robot controller in order to determine the exact dynamic systems modeling system that uncertainty is difficult for nomadic controlled robot direction angle by ultrasonic sensors throughout controlled performance tests. In additionally, this study is an in different ways than the self-driving simulator in the development of ultrasonic sensors and unmanned remote control techniques used by the self-driving robot controlled driving through an unmanned remote controlled unmanned realize the performance of factory automation.

본 연구의 목적은 IT직업훈련의 경제적 성과를 측정하는데 있다. 경제적 성과의 측정은 두가지 측면 즉 고용과 임금의 관점에서 행해졌다. 사용된 자료는 1998~1999년의 한국노동패널조사 자료이며 대상은 1차 년도의 실업자 또는 실망실업자 1,877명이다. 본 연구의 주요 결과는 다음과 같다. 첫째, 취업효과에 있어 IT교육훈련의 질적인 측면의 중요성이 두드러지게 부각되었다. 단순히 IT직업훈련의 유무가 취업에 '음'의 효과를 가지는 것에 비해 6개월 이상 IT직업훈련을 사람은 그렇지 않은 사람에 비해 취업될 확률이 24%나 높게 나타났다. 둘째, 취업효과를 학력별로 살펴볼 경우, 고등학교 이하의 그룹에서는 6개월 이상 교육받은 사람은 그렇지 않은 사람에 비해 취업될 확률이 38% 높은 것으로 나타났는데, 이 수치는 고려된 다른 어떤 변수들보다 높다. 셋째, 취업효과에 비해 IT직업훈련이 임금에 미치는 효과는 뚜렷하게 나타나지 않았다. 넷째, 비 IT직업훈련도 마찬가지이지만 특히 IT직업훈련의 경우 공공기관보다 민간기관에서 직업훈련을 받는 것이 또한 타인(정부 혹은 회사)이 비용을 부담하는 것이 취업에 유리한 것으로 나타났다. In this paper, we examined that whether IT job-training affects employment and insures job to pay high salary. This paper reports that all job-training overall affect not only employment but wage premium. even though the effect on wage premium is somewhat weak. In particular, the effect of IT job-training on employment is obvious and get stronger as training period increases in the low-educated group. In the case of the persons to receive IT job-training more than 6 months, the probability to get job is found to be higher by 38% than persons without receiving any other job-training

Pseudomembranous colitis (PMC) is a disease caused by Clostridium difficile proliferation. The causative drugs are clindamycin, third-generation cephalosporins, flouroquinolone and so on. Rifampicin has been reported as a cause of PMC in the 1980s, and the frequency of PMC is increasing because rifampicin is a first line drug for anti-tuberculosis therapy. Two patients were recently admitted to our hospital due to watery diarrhea for 1 month and they were diagnosed with PMC by sigmoidoscopy. Their onset age were 74, 72 years old and latent period of symptoms were 60, 129 days, respectively. In one case, the patient displayed coexisting hypertension and diabetes. The clinical symptoms improved after discontinuing the rifampicin and then administering oral metronidazole. We report here on two cases presumed to be rifampicin-induced PMC.

A 40-years-old woman was admitted to this hospital with flank pain and high grade fever for 2 weeks. As a matter of her past history, extracorporeal shock wave lithotripsy (ESWL) was performed for treatment of renal stones 5 years ago. Her abdominal CT findings were hydronephrosis with pyonephrosis and renal stones. Antibiotics administered for 5 days had no effects on her symptom improvement. A right ureteral stricture was noticed by ultrasonography follow up. We inserted double J stent and continued antibiotics therapy for 10 days, and then her fever was disappeared and flank pain was improved. ESWL is one of the most important treatment of renal and ureteral stone. However, its complications should not be negligible including bleeding, pain, ureteral obstruction, infection and so on. Complications of ESWL can be divided into acute and chronic courses. When we treat pyelonephritis patient with past history of ESWL, possibility of ureteral stricture must also be considered. In this study we report a case of pyelonephritis caused by ureteral stricture, possibly as a chronic complication of ESWL performed 5 years earlier

Erythrocyte sedimentation rate is influenced by plasma protein, red cell itself and physiological conditions and it is clear that the measurement of erythrocyte sedimentation rate varies with technique and various environmental factors. The effect of temperature, angle of test tube, and osmobility with different percent of NaCl solution on erythrocyte sedimentation rate on sheep was determined by modified Westergren method. In sheep, as the angle of Westergren tube was decreased from $90^{\circ}$ to $45^{\circ}$, erythrocyte sedimentation rate was increased in both diluted plasma and NaCl solutions. As temperature was increased from $4^{\circ}C$ to $20^{\circ}C$ at $45^{\circ}$ angle. erythrocyte sedimentation rate was increased. In ruminants, this modified Westergren methods, erythrocyte 1 : plasma 9 instead of erythrocyte 4 : plasma 6(whole blood), enable them to have meanings as dog therefor, using this method, clinical can determine the erythrocyte sedimentation rate of ruminants for diagnosis. Because erythrocyte sedimentation rate was changed according to the angle of Westergren tube, temperature as erythrocyte diluted with NaCl, this study detected that the change of temperature, the angle of Westergren tube could change erythrocyte sedimentation rate by effecting red cell itself. The increase of osmobility owing to change of NaCl percent resulted in the decrease of rapid erythrocyte sedimentation rate. So this fact indicate that deformibility and the change of red cell volume have meaning in the change of erythrocyte sedimentation rate.
