고전건축 이나 현대건축 모두 각자의 완벽함을 추구한다. 그러나 이 완벽성은 때때로 여러 가지 이유로 변형된 형태로 나타나게 된다. 본 연구는 르네상스 시대의 몇몇 건물의 입면과 평면을 분석하여 변형의 원리를 세가지 (precomposition, composite, extracomposition)로 분류, 분석하고 이를 토대로 새로운 구성원리인 "탈구성 (decomposition)"의 체계를 정립한다. 탈구성은 이제까지의 존재론적인 개체보다는 생성론적이고 과정적인 개체의 가능성이다.

Exposure to the posterolateral comer of the tibial condyle was difficult due to narrow joint space and meniscus. From l995. 1. to l996. 4.. the authors operatively reduced and internally fixed 9 cases of lateral tibial plateau fractures using lateral meniscal incision with minimal detatchment and retraction to improve visualization posterior aspect of articular cartilage Eight of the 9 cases were studied with three dimentional computerised tomogram and 1 case with roentgenographic tomogram to evaluate the shape, site and degree of comminution of the fracture fragments. ROM exercise was started at weeks postopratively, manipulation under anesthesia were done in 3 cases at 12 weeks postoperatively. The follow up period was 13 months (from 8M to lyr 11M). The results were obtained as follows, 1. Seven cases were split depression type, one was pure depression type and one was bicondylar type. 2. Articular depression were posterolateral aspect in 8 cases, and lateral aspect in one case. The degree of depression was average 15 mm(range from 6mm to 22mm). 3. Six of the 9 cases had peripheral tear of the lateral meniscus 4. Second look arthroscopy shows that the incision site of the meniscus were thinned but completely healed in 3 cases. 5. The ROM of the knee joint were 0 - over l35 in seven cases. 0° - 90° in one case, 30- 60° in one case. This meniscal incision approach was one of the effective methods that provides exposure of the entire articula surface of the lateral tibial condyle easily to allow accurate reduction.

Traumatic Posterior hip fracture-dislocation is uncommon injury, which induces the traumatic arthritis, joint contracture and avascular necrosis of the femoral head as a late complication. Among 23 patients with traumatic fracture-dislocation of the hips, 13 patients who underwent operative intervention were reviewed retrospectively: all patients were men ranging from 24 to 59 years old. A dash-board injury of car accident was leading cause of the traumatic dislocation in this series(9 cases, 64%). Associated injuries were found in 11 cases(84%). In follow-up ranging from 12 months to 36 months(averge, 18 months). Ten were treated by closed reduction; 6, by closed reduction followed by subsequent open reduction and internal fixation for unstable fracture of the acetabulum; 3, by primary open reduction; and 4, delayed open reduction. The results according to the Epstein and Thompson clinical criteria for evaluating results were good at 5 of 6 patients treated by closed reduction followed by open reduction for acetabular fracture. It was concluded that early closed reduction followed by open anatomic reduction with removal of all loose fragments of bone and cartilage and restoration of stability by intemal fixation of the fracture of the acetaulum offers the best prognosis.

Purpose: Although fracture of the body of the scapula have been treated successfully by conservative treatment but residual deformity was high and related to the residual symptom. Authors had done open reduction and internal fixation with wiring in the case of severe displacement of the fracture fragment of the body of scapula and analyzed that results. Material and Methods: Authors treated 18 cases of fracture of the body of the scapula in 17 patients from October, 1985 to June, 1996. Conservatively treated group was 12 cases which has less than 2cm displacement and operatively treated group was 6 cases which has more than 2cm displacement of the fracture fragment. Internal fixation was done with wiring. All cases was followed up average l year 9months (from 13months to 8year 8months) and evaluated by McGinnis assessment system. Results: All cases united within ten weeks. Five cases in the operatively treated six cases got anatomic reduction and stable fixation with wiring and had no operation related complication. Operatively treated group has average 2.83 associated injury and conservatively treated group has average 1.87. Neurovascular complication compromised the results. Conclusion: Operative treatment of the fracture of the scapular body can reduce the residual deformity and residual symptom in the severely displaced case and facilitate early rehabilitation.

췌장 질환에서 혈청 및 대변 pancreatic elastase-1 측정의 임상적 의의

목적 : 췌장 질환에서 혈청 및 대변 PE-1을 측정하여 췌장 질환의 감별 진단 및 췌장 외분비 기능의 평가 방법으로 PE-1이 유용성이 있는지 알아보고자 하였으며, 이를 만성 췌장염 환자에서 secretin-CCK 자극 검사와 비교 관찰하여 PE-1의 임상적 유용성을 평가하고자 하였다. 방 법 : 1997년 2월부터 1998년 3월까지 고려대학교 병원에 입원한 췌장 질환 79예(급성 췌장염 26예, 만성 췌장염 23예, 췌장암 30예)를 대상으로 혈청 및 대변 PE-1을 측정하였으며, 만성 췌장염에서는 순수 췌액을 이용한 췌장 외분비 기능 검사를 동시에 실시하였다. 결 과 : 만성 췌장염 환자에서 secretin-CCK 자극 후 췌액 분비량은 29.2 3.9 ml·30 min-1, 아밀라제 분비량 2,320.8 372.1 U·30 min-1, 그리고 중탄산염 분비량은 2.9 0.5 mEq·30 min-1으로 정상 대조군보다 모두 의미 있게 저하되었다. 또한 Cambridge 분류에 따른 대변 PE-1 농도는 경증에서 366.0±127.8 μLμg/g으로 대조군과 유의한 차이가 없었으나 중등도에서는 232.8±138.5 μLμg/g, 중증의 경우는 71.3±58.0 μLμg/g을 나타내어 양군에서 모두 대조군에 비해 의미 있게 감소되었다(p$lt;0.001). 대변 PE-1은 췌장암과 만성 췌장염에서 비해 모두 통계적으로 의미 있게 높았으나(p$lt;0.001), 급성 및 만성 췌장염 양군간에 유의한 차이는 없었다. 결론 : 췌장 질환에서 혈청 PE-1 농도의 측정은 췌장 질환의 감별 진단에 도움을 주지는 못하였으나, 대변 PE-1 농도의 측정은 췌장 외분비 기능 저하 정도를 반영하는 검사로 유용하였다. 특히 만성 췌장염에서 대변 PE-1 측정은 중등도 이상의 병변에서 췌장 외분비 기능을 평가하는데 민감도가 높았으며, 이는 순수 췌액을 이용한 secretin-CCK 검사법과 유사한 성적을 보여 향후 임상에서 비교적 쉽게 이용할 수 있는 비침습적이며 정확한 췌장 외분비 검사 방법으로 생각된다. Backgrounds : The aims of this study were to evaluate the diagnostic value of pancreatic elastase-1(PE-1) in patients with pancreatic diseases and compare the significance of PE-1 with that of pancreatic exocrine function test by pure pancreatic juice (PPJ) collection. Methods : For evaluation of PE-1, seventy nine patients with pancreatic diseases were examined. For evaluation of exocrine pancreatic function by PPJ, twenty three patients with Chronic pancreatitis(CP) were examined. PPJ was collected by endoscopic cannulation of main pancreatic duct under the intravenous bolus injection of secretin (0.25 CU/kg body weight) and cholecystokinin (CCK, 40 ng/kg body weight). Results : Pancreatic exocrine functions were significantly decreased in patients with CP showing moderate and severe ductal changes on pancreatogram. The mean concentration of fecal PE-1 was significantly decreased in patients with CP and pancreatic cancer, but not in patients with acute pancreatitis. When we analyzed the PE-1 concentration according to Cambridge classification, the concentration of fecal PE-1 was significantly decreased only in patients with moderate and severe CP. With a cut off of 200 ug fecal PE-1/g, the sensitivity of PE-1 was 25%, 60%, and 100%, respectively, for mild, moderate and severe CP, and the specificity was 88.1%. The mean concentration of serum PE-1 was increased both in patients with acute and chronic pancreatitis, but there was no difference between both group. Conclusion : Fecal PE-1 is useful for diagnosis of pancreatic exocrine insufficiency in patients with CP, especially in moderate and severe grade of pancreatic exocrine insufficiency. The diagnostic value of fecal PE-1 was also similar to secretin-CCK test in pancreatic exocrine insufficiency.(Korean J Med 58:392-401, 2000)
