최근 한반도를 통과했던 태풍 중 그 규모가 커서 海上에서 발생된 颱風波浪에 의해 특히 남해안 지역에 큰 재해를 준 1986년 태풍 Vera(8613)호 통과시에 南海의 거문도와 거제도 海上에서 동시에 태풍파랑을 관측하였다. 관측된 태풍파랑의 재현을 위하여 유럽의 북해를 대상으로 최근 연구개발된 Hybrid Parametric Wave Model(HYPA)을 적용하여 Vera 통과시의 파랑분포를 수치적으로 계산하였으며, 그 계산결과를 관측치와 비교하였다. 또한 태풍파랑의 추정에 주로 사용되어온 Wilson모델의 결과와도 비교하여으며, HYPA모델의 결과가 Wilson모델에 비해 훨씬 관측된 파랑자료에 근접함을 보였다. 따라서 본 연구를 통해서 한반도 근해상에서 발생되는 태풍파랑의 예측과 추정에 있어 HYPA모델에 매우 정확함을 보여주었다. During the passage of Typhoon Vera(8613) which causes the heavy natural disasters, especially, on the southern coast of Korea, waves were simultaneously measured at two different locations of the South Sea, that is, near to the Geomun and the Geoje Islands. In order to reproduce the measured typhoen-waves, Hybrid Parameteric Wave Model(HYPA) which has been developed for the North Sea was adopted to calculate numerically the waves generated by the Typhoon Vera. The model results were jilter-compared with the measured waves, and also with the results of Wilson model which has been widely used for the hindcast of typhoon-waves. HYPA's results show in the closer ageement with the measured waves than those of Wilson's. Based on these comparisons, HYPA model can be used for more accurate forecast and hindcast of typhoon-waves in Korean Seas.

The anterior cruciate ligament (ACL) of the knee is a primary anterior stabilizer and secondary rotatory stabilizer of this joint. Anterior cruciate ligament insufficiency can lead to degenerative arthritis and functional instability, and is also associated with a high incidence of meniscal tears. The relatively poor results generally obtained with conservative treatment of torn ACLs have led orthopaedic surgeons to either primary repair or reconstruction of this joint. The treatment of acutely torn anterior cruciate ligament remains a controversial subject. The purpose of this study is to compare the result of primary repair and arthroscopic reconstruction. Authors compared the results of 20 primary repairs(Group I) and 20 arthroscopic reconstructions(Group II) that were treated from January 1988 to December 1994. The results were as follows : 1. 34 males and 6 female ; the average age was 33 years. 2. Most common injury mechanisms were traffic acident(28 case) and sports injury(10 case). 3. Most common associated injury was medial collateral ligament rupture. 4. Group I showed postoperatively 12 negative anterior drawer test, 11 negative Lachman test and 11 negative pivot shift test and Group II showed postoperatively 17 negative anterior drawer test, 16 negative Lachman test and 17 negative pivot shift test. 5. In postoperative Lysholm knee scoring scale, group I showed 82 points and Group II showed 94 points. 6. In postoperative KT-20001 arthrometer, 12 cases in Group I and 17 cases in Group II showed less than 3mm in 20-D. 7. In postoperative KT-2000 arthrometer, 11 cases in Group I and 16 cases in Group II showed less than 3mm in MMD.

The Taegeuk Poomse 1 through 8 of Taekwondo are based upon eight major branches of philosophical theories. The propose of this study was to investigate the nfluence of Taekwondo poomse trainning on heart rate, MVO2, energy metabolism in primary school students. Subjects for this study were eight male the fifth∼sixth grades students who participated in exercise program consist of Taekwondo poomse trainning in dojang which is located in Shinlim-2dong, Kwanak-Gu, Seoul(12.7± 0.5years, 150.8 ±4.6cm, 45.1 ± 9.4kg, 24.9 ± 9trainning length). The results of thet this study are as follows: 1) The average of heart rate was Taegeuk Poomse 1 through 8 of Taekwondo 90.57± 4.gbeats/min in rest and 139.7 ± 17.5beats/min in exercise. The minimum heart rate was 89.0±2.8, peak heart rate was 167.1 ±6.4 in exercise. It was ranged from 42% to 80% 2) of the max heart rate and ranged 42 to 65%HRmax. Taegeuk 1 Jang was differenced with others Jangs significantly(p<0.05), 2) The time of the Taegeuk 1 through 8 Jang of Taekwondo was 5minutes 12seconds. Heart rate was ranged from 90.6 ± 7.85beats/min to 171.8 ±8.Ibeats/min and increased linearly. 3) The average of the MVO2 was 11.1 ±0.78mmHg · bpm-3 in rest and 19.1 ± 1.2mmHg ㆍbpm-3 in exercise. MVO2 was ranged from 10.5mmHg · bpm-3 to 20.3mmHg · bpm-3. There were not difference between Taegeuk Poomses(p<0.05). 4) The energy metabolism was as follows: Mean VO2 Respiratory exchange ratio, energy consumption were 0.51(V02L/min),0.71(RQ),2.32Ckca1/min) in rest respectively. but In exercise Mean VO2 Respiratory exchange ratio, energy consumption were 0.89 ± 0.18( V 02L/min), 0.79±0.08(RQ), 4.26±0.51(kcal/min) respectively . The difference was only between Taegeuk 1 Jang and Taegeuk 3 Jang(p<0.05). This study showed that the Taekwondo Poomse trainning was proper exercise for fitness, body composition and weight control in normal, abnormal(obese) children because the Taekwondo trainning are dynamic and exciting sport.

The present study is aimed to survey the aircraft noise around Cheongju International Airport, so the survey on the aircraft noise was undertaken from July 7 to July 13, 2002 continuously. As a result, it was found that number of passing aircrafts and WECPNL value per day are different with days of the week. On Wednesday, Saturday, and Sunday the influence of aircraft noise was lower than that on Tuesday and Thursday. The aircraft noise level of three residential areas around the airport was examined. The noise levels of 1.2km, 1.0km and 4.0km away from the airport runway were 74.7, 83.3, 67.7 WECPNL respectively. It was found that there is little affect of noise on residential life in two surveyed areas, but in the other area, noise is so loud that it should be anticipated to be noise damaged area.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

석원익(Won Ik Seok),이광범(Kwang Byum Lee),이종민(Jong Min Lee),엄기남(Gi Nam Um),윤성준(Seong Jun Yoon),최수란(Soo Lan Choi),김석영(Seok Young Kim),김광준(Kwang Jun Kim),이순표(Soon Pyo Lee),이지성(Jee Seong Lee),박찬용(Chan Yong Pa 대한산부인과학회 2002 Obstetrics & Gynecology Science Vol.45 No.6

목적 : 폐경상태에 따른 자궁경부 세포진 검사상 AGUS의 조직학적 결과 및 진단적 접근방법의 차이에 대한 임상적 중요성을 평가하고자 하였다. 방법 : AGUS로 진단된 104명 중 추적관찰이 가능했던 87명을 대상으로 폐경상태에 따른 조직학적 결과 및 진단 방법에 대한 평가를 하였다. 결과 : AGUS로 진단된 87명 중 폐경기 이전의 환자와 폐경 후 환자는 각각 46예 (52.9%)와 41예 (47.1%) 이었다. 87명중 70명 (80.5%)에서 중요한 조직학적 소견을 보였고, 이중 침윤성 질환을 보인 폐경기 이전 및 폐경 후 환자는 각각 19명 (41.3%)과 31명 (75.6%)으로, 폐경 후 환자에서 폐경기 이전 환자에 비하여 침윤성 암종이 유의하게 많이 관찰되었다 (P=0.002). 또한 진단방법의 평가에 있어 폐경 후 환자에서 폐경기 이전 환자에 비하여 제2군의 검사가 통계적으로 유의하게 많이 필요하였다 (P=0.018). 결론 : 자궁경부 세포진 검사상 AGUS는 추후의 조직검사에서 비침윤성 및 침윤성 병변의 높은 빈도와 관련되어 있다. 특히 폐경 후 환자에서는 제 1군의 검사 후 설명되지 않는 AGUS 환자에서 자궁경 및 자궁내막 병변의 잠재성의 병리상태 뿐만 아니라 드물지만 위장관, 난관, 난소 또는 유방 등 자궁 이외의 병변의 가능성을 배제하기 위해 보다 적극적인 검사가 추천된다. Objective : To evaluate the clinical significance of AGUS including histologic results and diagnostic modalities according to menopausal status. Methods : One hundred and four patients with AGUS were identified. Corresponding biopsies were available for 87 of these cases. The evaluation for histologic results and diagnostic modalities was made according to menopausal status. Results : Among the 87 patients with AGUS, the number of premenopausal and menopausal patients were 46 (52.9%) and 41 (47.1%), respectively. Over all, 70 (80.5%) of 87 patients were found to have important histologic findings and of them, premenopausal and menopausal patients with invasive diseases were 19 (41.3%) and 31 (75.6%) respectively. There were significant differences in pathologic findings between premenopausal and menopausal patients indicating more invasive lesions in menopausal than premenopausal patients (p=0.002). For the evaluation of diagnostic modality, the second arm was significantly more needed for menopausal than premenopausal patients (p=0.018). Conclusion : AGUS on pap smear represents a cytologic diagnosis associated with high incidence of underlying preinvasive and invasive lesions, especially in postmenopausal patients. Thus aggressive work-up is recommended to rule out the potential pathologic conditions in endocervix, endometrium and rarely extrauterine lesions such as gastrointestinal, tubal, ovarian or breast in patients otherwise unexplained AGUS after careful first arm work-up.

An improving example for traditional rapid mix system was studied in the base of mechanisms of alum coagulation. Local status of the major water treatment plants was also investigated and evaluated for upgrading these plants. A new design and operating criterium for rapid mix system was proposed to velocity gradient, G of 1,000-1,500 sec^-1 and detention time, t of 1 sec from the results of experiments and literature reviews. Comparing the present rapid mix system to this criterium, apparent difference existed between them. In this study, for improving Seongnam water treatment plant, a design criterium of velocity gradient, and detention time was set to 1,100 sec^-1, 1 sec, respectively. A new rapid mix system adopted the nozzle injection countcurrently cross the inlet pipe to the whole area. The injection velocity was 17m/s, nozzle diameter was 1.0mm, and number of nozzle was 70. The new modified system without running present four 75 HP agitators was able to improve water quality(based on sedimentation effluent) by 15-35% and to reduce electrical energy by 98%.
