Purpose: The aim of this study is to prepare medical staff in order to prevent medical malpractice litigation through analysis of litigation cases related to the department of surgery in Korea. Methods: A total of 94 litigation cases related to the department of surgery, where a certain amount of payment was ordered to the defendant between 2005 through 2010, were analyzed. We examined time of occurrence, amount claimed and awarded in damages, plaintiff claims, and court opinion. Results: An average of 3.2 years was spent from the date of the incident occurring to the end of the litigation procedures. The average amount awarded in judgments for damages was 59,708,983 ± 67,307,264 (range, 1,700,000–365,201,482) Korean won. Cases were found involving the following opinion of the court: violation of duty of care (49 cases), violation of informed consent (7 cases), violation of duty of care and informed consent (5 cases), and settlement, reconciliation, and others (32 cases). By analyzing defendants’ negligence in court opinions, diagnosis (30.8%) was the most common, followed by post-operation management (27.7%). Conclusion: Physicians have to conduct treatment and surgery based on exact diagnosis and be careful to observe patients’ conditions and symptoms after surgery. It is essential to identify the current status and characteristics of medical litigation for reducing further litigation and improving patient safety. In order to create a safe medical environment, national efforts should be made not only by individuals but also at the national level.

본 연구에서는 흙막이벽 설계시 널리 사용되고 있는 SUNEX 프로그램을 이용하여 Top-Down 공법이 적용된 지중연 속벽, 주열식 흙막이벽 (CIP벽, SCW벽)의 변형거동을 분석하였다. 해석프로그램에 Rankine의 토압(l857), Terzaghi and Peck의 토압(1967), Tschebotarioff의 토압(1973), 홍원표·윤중만의 토압(1995a)을 적용하여 흙막이벽의 수평변위를 예측하였다. 프로그램 해석결과, 흙막이벽의 수평변위량은 토압의 종류에 따라 큰 차이를 나타내고 있다. 홍원표·윤중만의 토압(I995a)을 적용하여 얻은 흙막이벽의 예측수평변위량이 실측수평변위량과 가장 유사하게 나타났다. 따라서 프로 그램 해석시 홍원표·윤중만의 경험토압(l995a)을 적용하면, Top-Down 공법이 적용된 흙막이벽의 변형거동을 비교적 정확히 예측할 수 있다. Abstract: The behaviors of a diaphragm wall and a contiguous pile wall such as CIP (Case-in-place pile) and SCW (Soil-cement wall), applied to the top-down construction method, were analyzed using the SUNEX program, which is widely used to design earth retaining walls. Four types of earth pressures, as described by Rankine (1857), Terzaghi and Peck (1967), Tchbotarioff (1973), and Hong and Yun (1995a), were applied to the analysis program to predict the lateral displacement of walls, The results show that the displacements of an earth retaining walls vary with the applied earth pressure. The predicted lateral displacement based on Hong & Yun`s (1995a) earth pressure is similar to the measured displacement. Therefore, the actual lateral displacement of an earth retaining wall, as applied to top-down construction method, can be accurately predicted by using an analysis program considering Hong and Yun`s (1995a) earth pressure.

본 연구에서는 지중연속벽 설계시 사용되는 범용 해석프로그램에 Rankin(1857)의 이론토압과 홍원표와 윤중만(1995a)의 경험 토압을 각각 적용하여 Top-Down 공법에 적용된 지중연속벽의 수평변위를 분석하였다. 그리고 이들 해석 프로그램에서 산정된 예측변위량과 지중경사계로 측정된 실측변위량을 비교 검토하였다. 현재 지중연속벽 설계에 적용되는 해석프로그램에는 Rankine의 토압이 주로 적용되고 있다. 검토결과, 지중연속벽의 예측수평변위는 적용되는 토압에 따라 상당히 큰 차이를 나타내고 있다. Rankine의 토압을 적용하여 산정된 예측수평변위 형상은 실측결과와 큰 차이를 보이고 있으며 벽체의 하부에서 예측치가 실측치보다 과다하게 산정되었다. 반면, 홍원표·윤중만의 토압을 적용하여 얻은 예측수평변위 형상과 최대수평변위 량은 실측결과와 유사하게 나타났다. 따라서 Top-Down 공법이 적용된 지중연속벽의 설계시 Rankine의 토압보다는 홍원표·윤중만의 경험토압을 적용하는 것이 적합함을 알 수 있다. The Rankine(1857)'s earth pressure and the Hong and Yun(1995a)'s earth pressure was applied to analyze the lateral displacement of diaphragm wall applied to the Top-Down construction method using the computer program, which is a common design program for diaphragm wall. The lateral displacement estimated by the computer program was compared with the lateral displacement measured by inclinometer. The Rankine's earth pressure has been widely used to design the diaphragm wall in the analysis of computer program. As the result of comparison, the lateral displacement of diaphragm wall was predicted differently according to the applied earth pressures. The behavior of lateral displacement predicted by the Rankine's earth pressure was different with displacement measured by inclinometer and the lateral displacement at the bottom part was overestimated. However, the lateral displacement predicted by the Hong and Yun's earth pressure is similar to the behavior and maximum value of real displacement. Therefore, the Hong and Yun's earth pressure is more suitable than the Rankine' earth pressure to design the diaphragm walls applied to the Top-Down Construction Method.

The reaction of o-phenylenediamine 5 with acrylic acid 11 in the presencce of P₂O5+H₃PO₄afforded benzodiazepinone 13 and pyridobenzodiazepinono 17. The reactions of o-phenylenediamine 5 with acrylic acid 11 in the presence of PPA or SiO₂afforded only benzodiazepinone 13. But the reaction of O-phenylenediamine 5 with acrylic acid 11 in the presence of acetonedicarboxylic acid 18 or acetonedicarboxylic acid 18 and PPA or acetonedicarboxylic acid 18 and SiO₂was respectively synthesized 2,4,4,-trimethyI-3H-5-hydro-1.5-benzodi-azepine 23 as new cyclic imine compound. We propose that formation of 2-(2`-imine)propyI-N-isopropylidene aniline proceed though 2-amino, N-isopropylidene aniline intermediate C and 2-(N-a-methylethyI) amino, N-isopropylidene aniline intermediate G. The reaction of o-phenylenediamine 5 with acetonedicarboxylic acid 18 in the presence of PPA or SiO₂or HCI gave 2,4,4-trimethyI-3H-5-hydro-1,5-benzodiazepine 23. Using acetone 19 instead of acetonedicarboxylic acid 18, the reaction of o-phenylenediamine 5 in the presence of PPA or SiO₂or acrylic acid 11 was synthesized 2,4,4-trimethyI-3H-5-hydro-1,5-benzodiazepine 23 as same product. And also the reaction of o-phenylenediamine 5 with acetone 19 and acrylic 11 in the presence of PPA or SiO₂was obtained 2,4,4-trimethyI-3H-5-hydro-1,5-benzodiazepine 23. In case of acetophenone 21 in stead of acceton 19, the reaction of o-phenylenediamine 5 in presence of PPA or SiO₂at 40~45℃ were obtained 2,4-diphenyI-4methyI-3H-5-hydro-1,5-benzodiazepine 24. The reaction of o-phenylenediamine 5 with crotonic acid 25 in the presence of PPA or P₂O5+H₃PO₄or SiO₂at 100~110℃ afforded respectively 4-methybenzodiazepinone 26 as 1:1 cycloadduct.

Peritonitis is a serious problem in patients undergoing peritoneal dialysis. Rarely pneumatosis intestinalis can occur as a complication of this infectious process. Pneumatosis intestinalis is a potential life threatening condition with a challenging management. The mortality of peritoneal dialysis patients with pneumatosis intestinalis secondary to mesenteric ischemia is almost 100%. We describe a rare case of pneumatosis intestinalis in a peritoneal dialysis patient who developed Staphylococcus aureus peritonitis which was initially treated with appropriate antibiotics. Since initial response to therapy was not achieved, an abdominal computerized tomography was done which revealed a pneumatosis intestinalis. A laparotomy was performed and small bowel necrosis was seen. A segmented resection with ileostomy, jejunostomy was done. Though surgical treatment was performed, the patient died in 2 weeks after admission. Pneumocystitis intestinalis in peritoneal dialysis peritonitis is a uncommon complication which requires prompt evaluation to rule out mesenteric ischemia as it carries a high mortality and its management will be surgical.

Double primary cancers are two independently developed cancers in an individual. There have been some reports on double primary cancer since Billroth reported it for the first time in 1879. Double primary cancer of the stomach and esophagus has been revealed a very low incidence worldwide. The incidence of an esophageal cancer with another primary cancer is reported to be 9.5∼27%, but double primary cancers in the esophagus and stomach have been rarely reported to our knowledge. In this study, we present here a case of double primary esophageal and stomach cancer in a 66-year-old man because of progressive dysphagia.

Patients with chronic renal failure (CRF) are known to be more susceptible to tuberculosis infection due to impairment of the host defense mechanism. Although extrapulmonary tuberculosis is more prevalent in those subjects and it may induce dismal outcome, its diagnosis has been challenging since there is no specific symptoms of the disease and the clinical course is usually atypical. Herein, We report a case of disseminated tuberculosis diagnosed by ultrasound-guided liver biopsy in a 31-year-old CRF patient presenting sustained fever despite broad-spectrum antimicrobial therapy and progressive cholestatic jaundice.
