Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

Exercise index(EI) was measured on 933 pneumoconiosis patients (865 patients with small rounded opacities and 68 patients with large opacities) and 176 suspected pneumoconiosis patients from Korean anthracitic mines, in order to evaluate the ventilatory impairment of pulmonary function according to the chest radiographic findings of pneumoconiosis. Exercise index was obtained from the maximum breathing capacity (MBC) and the exercise ventilation volume(EV) which were measured by spirometer and two step-test. Classification of pneumoconiosis was based on the international classification of ILO U/C. The results were as follows: 1. The mean value of E1 was significantly increased in pneumoconiosis patients with large opacities(46.0%) than in patients with small rounded opacities(26.5%) and with suspected pneumoconiosis(25.0%). The number of jpatients in substandard EI was 97.1% in patients with large opacities but 49.4% in patients with small rounded opacities and 40.3% in patients with suspected pneumoconiosis. 2. The mean values of EI and the number of patients in substandard EI were markedly increased in pneumoconiosis patients with small rounded opacities and suspected over 50 years of age. However, the number of patients in substandard EI showed no association with age in pneumoconiosis patients with large opacitis. 3. In pneumoconiosis patients with small rounded opacities, the mean values of EI and the number of patients in substandard EI showed significant association with the profusion (category) but no significant association with the type of small rounded opacities. 4. In pneumoconiosis patients with large opacities, the mean values of EI and the number of patients in substandard EI showed no significant difference between patients complicated with and without pulmonary tuberculosis. 5. No significant association of EI and the number of patients in substandard EI with the size of large opacities was observed in pneumoconiosis patients with large opacities, however, the mean values of EI showed increasing tendenccy in category B and C compared to category A.

본 연구는 우리나라 대학원을 육성코져 하는 의도에서 발달한 1980년도 文敎部 硏究費의 보조를 받아 우리나라에서의 정신의학분야 대학원생을 어떻게 선발하는 것이 최선이냐는 데에 대한 方案을 제시하는 데 그 목적을 둔 것으로, 저자들은 이에 수반하여 이분야 專攻醫의 선발방안도 아울러 연구코져 하였다. 먼저 저자들은 우리나라 현행 대학원생 선발의 예로 서울대학교를 들어 이를 검토한 결과 그 특징으로, 첫째 선발의 주도권이 해당 科(敎室)가 아닌 醫大에 있다는 것과, 두째 서류전형이 없고 면접고사는 형식적인 것에 불과한 반면 영어와 임상의학에 치중된 필기고사가 그 당락을 좌우한다는 사실을 발견·지적하였다. 다음 저자들은 우리나라 현행 전공의선발의 예로 서울대학교병원을 들어 이를 검토한 결과 그 특징으로 첫째 선발의 주도권은 형식상 병원측에 있으나 실제에서는 신경정신과측과 병원측에 양분되어 있었고 그 비중은 科側이 病院側 보다 높다는 인상을 받았다는 것이고, 두째는 이 역시 대학원생 선발과 마찬가지로 서류전형은 없고 영어와 전공과목인 2과목의 필기고사 성적에 그 당락이 좌우됨을 발견하였다. 이같은 우리나라 경우에 비해 Cornell 대학병원 정신과를 예로 든 미국의 전공의 선발과정의 특징은 첫째 서류전형에서 부터 출신의대와 의대성적을 중점 참고하여 탈락이 속출하고, 두째 필기고사는 없으되 다수의 면접위원에 의한 철저하고 엄격한 면접고사에서 최종 당락이 결정된다는 것, 세째 선발의 모든 권한과 책임이 전적으로 해당과에 부여된다는 점이었다. 위와 같은 자료를 준비한 뒤 저자들은 1981년 8∼9월 大韓神經精神醫學會會員으로 있는 專門醫(교수 포함)92명, 專攻醫 94명(대학원생 포함), 도합186명에게「전공의 및 대학원생 선발방안에 대한 질문서」를 발송하여 그 61%인 전문의 59명(전임교수 43명 포함)과 전공의55명(대학원생 49명 포함)도합 114명에게서 회신 받은 것을 종합·평가·분석하여 본선발방안을 작성하였던 바, 현재로서 이 방안은 본연구의 부수목적이었던 신경정신과 전공의선발에는 약간의 무리를 무릅쓰면 즉시 사용할 수 있는 것 임에 비하여 본 목적이었던 대학원생선발에는 그 대학원제도 자체가 지닌 산적한 制度上·運用上의 근본문제로 인하여 즉시 사용은 불가능한 상태임을 알아내었고, 따라서 저자들은 이들 妨害要素 4가지를 제시하면서 대학원 정책입안자들의 高次元的 決斷을 촉구하였다. 이러한 制約이 있음을 前提로 하여 著者들은 다음과 같은 精神醫學分野 大學院課程學生 選拔方案을 제사하는 바이다.―① 학생(전공의) 선발의 모든 권한과 책임은 醫大와 病院이 아닌 科와 敎室이 갖도록 한다. ② 응모에 마감은 해마다 정하되 각 대학원 또는 병원은 각기 독자적으로 다르게 일자를 정하는 것이 좋다. ③ 경쟁율이 높은 대학원 또는 병원은 書類銓衡을 일차적으로 하는 것으로 하되 주로 의대성적·인턴근무·성적·추천서·인턴병원에 관한 사항을 참작토록 한다. ④ 筆記考査는 폐지하던가 시행한다해도 전공과목·임상의학·영어의 3과목으로 제한하며 그 합격율을 최종선발인원의 倍數 이상으로 하도록 한다. ⑤ 面接考査를 철저하고 엄격히 장시간에 걸쳐 多數委員에게서 同一지망자에게 실시토록 하되 지식위주가 아닌 인간성과 자질평가에 주안점을 둔다. ⑥ 선발과정에 있었던 모든 토의·결정사항에 관계되었던 것을 文書化· 機密化하여 半永久 保存함으로써 公正度 유지에 전력을 다한다. No study has been known yet in Korea on evaluation of the students selection system in graduate course while there have been some outspoken critics to the present system in the past several years. Comparison between on-going Korean and American systems was made, and opinions of a group of 59 board-certified leading psychiatrists(including 43 full-time faculty staffs) and 53 psychiatric residents (including 49 graduate course students) on the ideal and best suitable selection system obtained via questionaire method were assessed. On the basis of this assessment, following recommendations were finally made for the future occasions of the selection: 1) Initiatives and whole responsibilities of the selection is preferred be lied in the hands of department of psychiatry instead of medical school authorities. 2) Different application time-limits set for each graduate school are desirable for the conveniences of applicants who want to apply for several places. 3) Preliminary selection on the basis of academic grades in medical school, hospital of the present internship, and recommendation lecters from deans and directors of internship is desirable. 4) Written test for evaluation of medico-psychiatric knowledges seems less important as it does not correctly reveal whole abilities of each applicant. 5) Interview by more than two faculty members for each applicant, not as oral-test style for medico-psychiatric knowledges only, but as evaluation of whole person, is strongly recommended. 6) Those above-mentioned ideas seem highly-reasonable and immediately applicable to the present psychiatric residents selection system without much difficulties, while those could cause severe turmoil in the present graduate school system unless there were some basic and radical changes in medical education system in Korea as to parallel to he international standard.

슬관절 전치환술시 슬개골 비치환술

조세현,정운화,천충우,윤영필 대한슬관절학회 2002 대한슬관절학회지 Vol.14 No.2

슬개골-대퇴골 관절의 합병증은 슬관절 전치환술 후 가장 흔한 합병증 중의 하나로, 이런 합병증을 예방하기 위해 슬관절 전치환술 시 슬개골을 치환할 것인가, 아니면 보존할 것인가에 대하여 아직도 많은 논란이 되고 있다. 1993년 8월부터 200년 8월까지 퇴행성 관절염 및 류마티스 관절염으로 슬개골 치환을 하지 않고 인공슬관절 전치환술을 시행한 환자 중 2년이상 추시가 가능했던 36명, 43례를 연구대상으로 하였다. 전례에서 슬개골의 퇴행성 변화에 관계없이 슬개골 보존술(즉 슬개골을 치환하지 않고 슬개골 성형술만 실시함)을 시행하였으며, 추시 기간은 최단 2년에서 최장 10년으로 평균 54개월이었다. 수술전 슬개골의 방사선 사진으로 정상 슬개골을 A군 (10례), 중등도의 퇴행성 변화를 B군 (20례), 심한 퇴행성 변화를 C군 (13례)으로 분리하여 세군의 슬관절 전방부 동통, 운동범위, 계단 오르기 능력 등의 임상적 소견과 슬개골 경사(patellatilt) 및 외측 슬개골 전위(lateral patella shift)의 두 가지 방사선사학적 소견을 비교 분석하였다. 35명중 퇴행성 관절염이 29명, 류마티스 관절염이 6명였으며, 임상적 분석은 American Knee Society Score(KSS)를 사용하였다. 최종추시시 평균 Knee Society Score (KSS)는 A군 93.1점, B군 92.7점, C군 94.2점이었다. 총 43례중 슬관절 전방부 동통을 호소한 예는 A군 2례, C군 2례로 4례 (9.3%)뿐이었으며, 이들은 보행 시는 동통이 없으나, 쪼그린 자세나 계단을 오르내릴 때 동통을 호소하였다. 세군간의 슬관절 운동범위, 계단 오르기 능력 등의 비교에서는 유의한 차이가 없었으며, 방사선학적 비교에서 외측 슬개골 전위는 유의한 차이가 없었고, 슬개골 경사는 A군과 B군에서는 유의한 차이가 없었으나, C군에서는 유의하게 차이가 있었으므로 술전 슬개골의 퇴행성 변화가 심할수록 슬개골 경사가 증가됨을 알 수 있었다(p=0.01). Patello-femoral problem is one of the common complications in total knee arthroplasty and whether to replace the patella or retain it has long been controversial in order to prevent the complications. 43 cases (35 patients) of total knee arthroplasty with patellar retention performed by single surgeon between August 1993 and August 2000 were reviewed retrospectively. The follow-up period averaged 54 months (range, 24-120months). The whole cases were divided into three groups according to the preoperative radiographs. Group A was normal patella (10 knees), Group B was borderline arthritic patella (20 knees), and Group C was severely deformed patella (13 knees). All of 43 knees, regardless of preoperative radiological degree of arthritis received patelloplasty including removal of osteophytes, subchondral shaving and lateral retinacular release was performed in 20 knees (47%). Each groups was evaluated in terms of the objective criteria of anterior knee pain, range of motion, stair climbing ability, and roentgenographic findings. All 35 patents were diagnosed as osteoarthritis in 29 and rheumatoid arthritis in 6. American Knee Society Score (KSS) was assessed for the clinical analysis and lateral patella shift and patella tilt were assessed for roentgenographic analysis. The mean Knee Society Score at final follow-up was 94 in group A, 93 in group B, and 94 in group C. Mild anterior knee pain was reported in 9.3% (Group A: 2 cases, Group C: 2 cases). patellar tilt was significantly higher in C group (oneway ANOVA test, p=0.01), representing that advanced patello-femoral arthritis caused increased patellar tilt. There was nither significant difference in terms of range of motion, and stair climbing ability nor of patellar shift among all three groups. TKA with patelloplasty, not resurfacing the patella, provided satisfactory results without significant problems regardless of the preoperative degree of patello-femoral arthritis.

Vibration-controlled concrete has been developed by using various concrete mixtures, such as latex, rubber powders, plastic resins and polystyrene(styrofoam). As part of the recycling research of obsolete aged <tires and plastic> materials, vibration-reducing mixtures are used for 10 concrete panels above 200 ㎏/㎠ in uniaxial compressive strength. Laboratory test and open space test have been carried out for the analysis of the impact wave, of which data have been transferred by the FFT technique to comparatively investigate damping ratios of 10 concrete panels. According to wave propagation analysis on vibration- controlled concrete for this research, it can be concluded that Latex concrete has relatively larger damping ratios than those for noncontrolled normal concrete with similar compressive strength.

A comparative study was undertaken to evaluate the contact Neodymium : yttrium aluminum garnet(Nd : YAG) laser system for vascular anastomosis of small caliber blood vessels(diameter 0.5-1.2mm) in the animal model. In this study 40 femoral arteries and 40 femoral veins of Sprague-Dawley rats were anastomosed by contact laser assisted microvascular anastomosis(LAMA) utilizing 3 stay sutures which were placed 120 degrees apart and the intervals welded with contact Nd : YAG laser unit, conventionally sutured anastomosis(CSA) served as controls. The time needed for vascular anastomosis, patency rate (immediate postoperative, postoperative 2nd day, postoperative 1 week, postoperative 4 week), gross and microscopic evaluations were compared to conventional microsurgical suture technique. The results are as follows : (1)Post-operative patency rate was 82.5% for femoral artery and 75% for femoral vein by contact LAMA technique compared to 90% and 75% by CSA technique at post operative 4 weeks. (2)Less time-consumed for arterial anastomosis by 6 minutes 23 seconds and venous anastomosis by 8 minutes 55 seconds with contact LAMA technique compared to CSA technique. (3)Grossly almost complete healing had taken place by post-operative 1 week by contact LAMA technique. (4)Aneurysm formation was 5% for femoral artery and 15% for femoral vein by contact LAMA technique compared to 5% and 10% respectively by CSA technique. (5)Microscopically, re-endothelization was complete by post-operative 7th day by contact LAMA technique. There was less medial hypertrophy and hyperplasia and also less inflammatory response compared to CSA.
