Purpose: The purpose of this study was to understand the effect of aquatic exercise on balance and depression of stroke patients. Methods: For 12 participants with stroke, six members of the experimental group and six members of the control group were randomly selected and arranged. Proprioceptive Neuromuscular Facilitation (PNF) lower extremity aquatic pattern exercise was applied to the experimental group. On the other hand, participants in the control group performed PNF lower extremity pattern exercise on the ground. Both exercises were performed 30 minutes per day, five times per week, for a period of six weeks. Balance was assessed using the Berg Balance Scale (BBS) and Timed Up to Go test (TUG). Depression was measured using the Center for Epidemiologic Studies depression scale (CES-D). Results: As a result of comparison within groups, the experimental group showed significant difference for balance and depression after the experiment (p<0.05). In comparison between the two groups, the experimental group in which aquatic exercise was applied showed more significant change in balance and depression than the control group (p<0.05). Conclusion: According to the results of this study, aquatic exercise was proven to enhance the balance and decrease the depression of stroke patients.

Purpose : The cause and pathogenesis of $Henoch-Sch\"{o}nlein$ purpura has been studied for many years but the results are disappointing. Recently the hypothesis that abnormalities involving the glycosylation of the hinge region of immunoglobulin Al(IgAl) may have an important role in the pathogenesis of $Henoch-Sch\"{o}nlein$ purpura is being approved. $Henoch-Sch\"{o}nlein$ purpura is the most common vasculitis Ihat affects children and the prognosis is good. But if kidney invovement occurs, the course may be chronic and troublesome. So we evaluated children with $Henoch-Sch\"{o}nlein$ purpura especially from the point of epidemiology and clinical manifestations. Methods : Investigation of 124 children who were diagnosed with $Henoch-Sch\"{o}nlein$ purpura at Inje University Ilsan Paik Hospital from December 1999 to July 2003 was performed retrospectively through chart review. Efforts were made to get informations about the profile, epidemiology, clinical manifestations, progress of the disease and recurrence rate of patients. Results : The patients were 69 boys and 55 girls, with a mean age of $6.1{\pm}2.7$ years at the time of data collection. The male to female ratio was 1.25 : 1. The occurrence rate was much higher in autumn(from September to November, 31.5%) and winter(from December to February, 28.2%) than in spring and summer, with a peak in November. Joint involvement was shown in 66.9% of patients mostly on the foot/ankle(75.9%), knee(39.8%). Seventy(56.5%) out of 124 patients had abdominal pain and 10 patients(8.1%) showed bloody stools. Renal involvement was observed in 24 patients(19.4%) after 21.1 days on the average. IgA was elevated in 10 of 21 patients(47.6%). $C_3$ and $C_4$ levels were normal in 40 of 49 patients (81.7%) and 47 of 48 patients(97.9%), respectively Antistreptolysin-O(ASO) titer was elevated over 250 Todd units in 29 of 62 Patients(46.8%). Mycoplasma antibody titer was elevated in 21 of 49 patients(42.9%) equal or greater than 1:80. Radiologic studies were peformed in 23 patients. Seven patients(30.4%) showed bowel wall thickening and one of them received intestinal resection and anastomosis operation due to terminal ileum necrosis. Eighty four patients took steroid 1.4 mg/kg/day in average. Recurrence rate was 2.5 in 37 patients(29.8%). Conclusion : $Henoch-Sch\"{o}nlein$ purpura in childhood appears most in about 6 years of age. The occurrence rate is much higher in autumn and winter relatively. Diagnosis can be made through the perspective history taking and the inspection of clinical manifestations, but the laboratory findings are not of great help. A small portion of the patients might show abdominal pain or arthritis before purpura develops, therfore various diagnosis can be made. Radiologic evaluation should be performed to avoid surgical complications in cases accompanying abdominal pain, and long term follow up should be needed especially in patients suffering from kidney involvement. In about 30% of the patients $Henoch-Sch\"{o}nlein$ purpura would recur. Steroid can be used safely without side effects. 목적 : 최근에 $Henoch-Sch\"{o}nlein$ 자반증의 원인 및 발병기전에 대한 연구가 진행되고 있으나 현재까지 뚜렷하게 밝혀진 것은 없으며 면역글로불린 Al이 중요한 역할을 하는 것으로 알려져 있다. 질환자체는 매우 흔하며 양호한 예후를 보이지만 신장에 침범된 경우 만성적인 경과를 취하는 경우도 있다. 따라서 저자들은 이러한 $Henoch-Sch\"{o}nlein$ 자반증의 연구에 도움이 되고자 역학, 임상양상 및 경과에 대해 조사하여보았다. 방법 : 1999년 12월부터 2003년 7월까지 인제대학교 일산백병원에서 $Henoch-Sch\"{o}nlein$ 자반증으로 진단된 124명의 환아들을 대상으로 역학, 임상양상 및 경과에 대해 차트분석을 통한 후향적 조사를 시행하였다. 결과 : 남아는 69명, 여아는 55명으로 남녀 비는 1.25:1이었다. 평균연령은 $6.1{\pm}2.7$세였으며 가을(9-11월, 31.5%)과 겨울(12-2월, 28.2%)에 상대적으로 호발 하였으며 11월에 가장 많이 발생하였다. 관절염은 66.9%에서 발생하였고 발/발목(75.9%), 무릎(39.8%) 순이었으며 환아의 56.5%에서 복통이 있었고 10명(47.6%)에서 증가하였으며 $C_3,\;C_4$는 각각 81.7%; 97.9%에서 정상이었다. ASO titer는 46.8%에서 250 Todd units 이상으로 증가되어 있었고 2명에서 S. pyogenes(group A)가 자랐다. 마이코플라즈마 항체가가 1:80 이상인 경우가 42.9%이었다. 방사선학적 검사는 23명에서 시행되었고 이중 7명(30.4%)이 장벽비대 소견을 보였으며 1명은 말단회장의 괴사로 인해 장절제 및 문합술을 받았다. 총 84명이 스테로이드 투여를 받았으며 용량은 평균 1.4mg/kg/day이었다. 재발은 37명(29.8%)에서 평균2.5회 발생하였다. 결론 :소아 $Henoch-Sch\"{o}nlein$ 자반증은 6세경에 가장 호발하며 가을과 겨울에 더 많이 발생한다. 검사소견은 진단에 많은 도움이 되지 않으며 자세한 병력청취 및 임상증상의 관찰이 진단에 중요하다. 일부 환아들은 복통과 관절염증상이 자반에 선행하여 나타나는 경우가 있어 다양한 진단을 내릴 수 있으나, 대부분 3-4일 이내에 자반이 발생하므로 성급한 진단은 피해야 한다. 복통을 동반하는 경우 드물게 수술적 합병증이 발생하는 경우가 있으므로 방사선학적 검사를 요하며 혈뇨를 보이는 경우에는 만성적인 경과를 취할 수 있으므로 지속적인 관찰이 요구된다. 환아의 30%는 재발하며, 스테로이드는 부작용 없이 안전하게 사용될 수 있다.

Study of the Switching Errors in an RSFQ Switch by Using a Computerized Test Setup

김세훈,백승헌,양정국,김준호,강준희,Kim, Se-Hoon,Baek, Seung-Hun,Yang, Jung-Kuk,Kim, Jun-Ho,Kang, Joon-Hee The Korean Superconductivity Society 2005 Progress in superconductivity Vol.7 No.1

The problem of fluctuation-induced digital errors in a rapid single flux quantum (RSFQ) circuit has been a very important issue. In this work, we calculated the bit error rate of an RSFQ switch used in superconductive arithmetic logic unit (ALU). RSFQ switch should have a very low error rate in the optimal bias. Theoretical estimates of the RSFQ error rate are on the order of $10^{-50}$ per bit operation. In this experiment, we prepared two identical circuits placed in parallel. Each circuit was composed of 10 Josephson transmission lines (JTLs) connected in series with an RSFQ switch placed in the middle of the 10 JTLs. We used a splitter to feed the same input signal to both circuits. The outputs of the two circuits were compared with an RSFQ exclusive OR (XOR) to measure the bit error rate of the RSFQ switch. By using a computerized bit-error-rate test setup, we measured the bit error rate of $2.18{\times}10^{-12}$ when the bias to the RSFQ switch was 0.398 mA that was quite off from the optimum bias of 0.6 mA.

본 연구는 개정 $\ulcorner$도서관법$\lrcorner$에서 도서관정책의 지방분권에 있어서 가장 핵심적 수단으로 제시하고 있는 지역대표도서관의 설립 또는 지정 운영이 보다 안정적으로 추진될 수 있는 방안을 모색할 목적에서 수행되었다. 이를 위해 지역에 따라 재정, 인력, 정책 우선순위 등에서 매우 큰 편차를 보이고 있는 시 도에게 지역대표도서관의 역할과 기능, 업무를 상세히 설명하고, 지역대표도서관 설립 운영과 관련해 도움이 될 수 있는 방안을 제시하고자 한다. This research aims to suggest ways of establishment and management of the Regional Central Libraries, which are expected to play an important role in promoting the quality of library services in metropolitan regions. The field survey for this research, however, shows that many regional governments have difficulties to establish and/or run the Libraries and the difficulties come from their inexperience in the library services. On the basis of the analysis, it suggests standard organizational structure of the Regional Central Libraries and specifies their services according to their roles and functions.
