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.

목적 : 3년간 서울시 강서지역의 1개 대학병원에서 입원치료를 받은 성인 급성 신우신염 환자를 대상으로 원인균과 항생제 감수성을 조사하고, 향후 급성 신우신염의 초기 경험적 치료 항생제를 제안하고자 하였다. 방법 : 1999년 1월부터 2001년 12월까지 3년간 고려대학교 의과대학 구로병원에 상부요로감염으로 내원한 16세 이상 환자 229명의 의무 기록을 검토를 통하여, 인구학적 특성, 원인균, 항생제 감수성, 초기 항생제 사용 양상과 입원기간을 조사하였다. 결과 : 연구에 포함된 229명을 118명의 단순 신우신염군과 111명의 복잡 신우신염군으로 구분 하였다. 단수 신우신염의 평균 발생 연령은 38.2세와 복잡 신우신염 56.1세로 복잡 신우신염 환자의 연령이 유의하게 높았다(P<0.001). 양군 모두에서 원인균 중 E. coli의 분리율이 가장 높았으며 항생제 감수성 결과 ampicillin, trimethoprim-sulfame-thoxazole에는 높은 내성률을 보였고, ciprofloxacin, gentamicin, cefotaxime에 대한 감수성은 비교적 높았으나 복잡 신우신염의 경우 단순 신우신염에 비하여 ciprofloxacin, gentamicin에 대한 감수성이 다소 낮은 것을 확인할 수 있었다. 평균 입원 기간, 항생제 투여 기간에 있어서도 복잡 신우신염군에서 유의하게 길었다. 결과 : 본 연구의 결과 서울의 강서 지역에서 대학병원급에 치료 의뢰되는 단순 급성 신우신염의 치료에 있어 1차 항생제로 3세대 cephalosporin, aminoglycoside, quinolone 중 한가지를 초기 경험적 치료제로 사용을 고려하여야 할 것으로 사료된다. Background : The purpose of this study is to recommend the initial therapeutic regimen for adult patients with acute pyelonephritis (APN) according to the changes of antimicrobial susceptibility patterns of causative microorganisms isolated from patients with APN. Methods : We reviewed medical charts of 229 APN patients, who had been treated at Korea University Guro Hospital from 1st of January. 1999 to 31st of December, 2001. We investigated the demographic data, clinical findings, durations of hospital treatment, antimicrobial susceptibility patterns of the causative microorganisms and initial antibiotic regimens in patients with APN. Results : In this study, 229 adult patients with APN were classified into simple APN patients (118 patients, 51.5%) and complicated APN patients (111 patients, 48.4%). Mean age of patients with simple APN was 38.2±14.1 years old and that of patients with complicated APN was 56.1±14.9 years old. Mean age of patients with complicated APN was significantly higher than that of simple APN patients (P<0.0001). Escherichia coli was the most common microorganism both in simple APN (96.7%) group and in complicated APN (90.6%) group. Antimicrobial susceptibility of E. coli was at the low level of ampicillin (31%/20%) and trimethoprim-sulfamethoxazole (42.6%/34.2%) in each group. In contrast, ciprofloxacin (11.5%/22.7%), gentamicin (16.4%/22%) and cefotaxime (0%/8.2%) resistance remained at relatively lower level. In comparison of simple APN with complicated APN, ciprofloxacin and gentamicin resistances were higher in complicted APN group. Average duration of hospitalization (5.9±2.3 days/8.2±4.6 days) and duration of antibiotic use (12.1±3.9 days/15.3±10.0 days) were significantly longer in complicated APN. Conclusions: The results of this study suggests that 3rd cephalosporin, aminoglycoside or quinolone antibiotic would considered as one of the initial therapeutic regimen for patients with simple APN in southwestern Seoul.

This paper presents a new vibration control device by which the mass and damping of a structure is increased equivalently. The vibration control system, named toggle-rotational inertia-viscous damper, can be utilized effectively in applications of small structural drift. Numerical analysis shows that because the relative drift of a structure can be effectively amplified by the toggle system, the device has a great performance in the vibration control without the increase of the damper capacity and size. It is also observed that vibration control effects is caused by the increase of equivalent mass and damping due to the rotational inertia and damping of the device.

Objectives : Euthymic patients with bipolar disorder have been reported to show deficits in sustained attention. This study aimed to compare the attention capacities of euthymic bipolar patients with those of control subjects using the sustained att-ention to response task (SART) and to examine the differences in the performance of SART related to the type of the stimulus. Methods : The four SART tasks were performed to measure attention capacities in 42 euthymic patients with bipolar dis-order and 28 control subjects. Happy, neutral, fearful faces and digit '3' were used as target stimuli in happy, neutral, fear and digit task conditions, respectively. The seventy of mood symptoms was assessed with 17-item Hamilton Rating Scale for De-pressive symptoms and Young Mania Rating Scale for manic symptoms. The efficiency estimate which reflects both the res-ponse accuracy and speed was used as the main outcome variable. Results : Bipolar patients showed significantly lower correct response rate than control group in all task conditions. Effi-ciency estimates of the bipolar patient group were significantly lower than those of the control group in the SART using facial stimuli, but not in the digit task condition. There was no significant difference in task performances related to the emotional categories of facial stimuli. Conclusion : Bipolar patients showed deficits in sustained attention even in the euthymic state. The attention deficits shownin the euthymic bipolar patients may be prominent in a more complex task condition with stimuli such as facial stimuli.

The metal salts of various fatty acids were prepared and their SEM data are collected. The morphology of metalated fatty acids (decanoic, stearic and 12-hydroxyst earic) showed more branched thread-like clusters than those of fatty acids. Among the prepared metal salts of various fatty acids, the morphology of lithium 12-hydroxystearate (Li-HSA) showed some similarity to the reticular structure suitable to be a proper thickener in grease formulation.

This paper presents the efficient system architecture of a digital studio and its operation and maintenance. This paper shows the overview of the system components and explains their technical features in detail, and discusses system installation and operational test procedures. And then technical requirements and procedural schemes for system implementation have been proposed and the operational organization, training programs, and maintenance planning have been qeneralized and analyzed. It shows that essential points for constructing the optimum system are to follow a supply-demand curve of its markets and industries and to make technical innovations of system implementation. Training programs for system operators and administrators are also very important factors. The integration of such factors makes it possible to construct the efficient a digital studio.
