콘크리트 구조물이 대형화됨에 따라 설계단면이 증대되어 상대적으로 많은 경제적 손실을 부담하게 된다. 따라서 단면을 감소시키면서도 소요의 하중에 안전한 구조물을 건설하기 위해서는 우선적으로 구조물 건설에 기초가 되는 고품질, 고내구성의 고강도 콘크리트 개발이 절실히 요구된다 본 연구에서는 일정 시멘트비 및 혼화재 비율하에서 소요의 워커빌리티가 확보되는 고강도 콘크리트를 시간과 온도의 변화에 따라 증기 양생하여, 압축, 인장, 휨강도 뿐만 아니라 파괴특성을 실험적으로 연구하였다. 시료 제작시 시멘트 입자 사이의 공극 및 불연속 영역을 충전하여 고밀도화하기 위한 콘크리트용 혼화재로 시멘트 비표면적이 상당히 작은 초미립 분말인 실리카흄을 이용하였다. 또한 AE감수제 및 고성능 유동화제를 사용하여 혼화재의 첨가에 의하여 발생될 수 있는 워커빌리티의 감소를 방지하였다. 실험결과에 의하면 일정 양생 지속 시간하에서 온도의 증가에 따라 콘크리트의 압축, 인장 및 휨강도가 전반적으로 증가하였다. 동일하게 일정 온도하에서 양생 지속시간이 커짐에 따라 강도들이 증가됨을 알 수 있었다. 따라서 상대적으로 높은 온도와 긴 지속 양생 조건하에서 파괴에 대한 저항력이 크게 나타났다. The compressible, tensible, and flexibleresistance of the high strength concrete is analyzed by the experimentation in the present study. For the test, we cure several samples with the silica fume as a mixture being become dense the spaces between the particle of cement under the variation of both the temperature and the curing-interval. Then, the superplasticizer and the ezcon are also used to satisfy the required workability for construction. The compressible, tensible, and flexible resistances to a stress are increased as increasing the temperature and the time interval for the curing. Therefore it is concluded that the overal fractural and mechanical properties is improved by mixing the silica fume into the cement.

Amyloidosis is characterized by extracellular deposition of protein fibrils in one or multiple organs. AA amyloidosis is secondarily occurred to be related with chronic infections or inflammatory diseases. We report a 67-year-old man suffered from secondary AA amyloidosis related with chronic Clostridium difficile colitis after repeated total hip replacement surgery. Infection control is the most important treatment of AA amyloidosis secondary to chronic infection. However, the patient’s C. difficile colitis was not controlled well, eventually toxic megacolon with sepsis was developed. Consequently, he had to take total colectomy, but he expired with multi-organ failures. We suggested that early surgical procedure might be one option for intractable C. difficile colitis complicated with secondary amyloidosis.

Caroli syndrome is a rare congenital disorder of intrahepatic bile ducts that is characterized by intrahepatic bile duct dilatation and prominent fibrosis in the portal area. In Korea, only 2 cases have been reported in adult age. A 23 year old male visited emergency room for hematemesis. He had received splenectomy for unclear causes several years ago. He didn’t drink alcohol and serologic tests for viral hepatitis were all negative. Liver imaging study revealed multiple intrahepatic large bile duct dilatation with central enhancing dots which acknowledged the presence of Caroli’s disease. Portal hypertension is not common manifestation of Caroli’s disease itself but a major problem when it combined with congenital hepatic fibrosis. Liver biopsy was performed and showed irregular fibrosis containing small bile ducts. He was counseled for the future liver transplantation. We present a rare case of Caroli syndrome confirmed by CT and liver biopsy in adult.

목적: 태아 배벽갈림증의 주산기 경과 및 태아 치료와 산후 결과를 분석하고자 한다. 연구 방법: 1997년 3월부터 2007년 4월까지 배벽갈림증으로 진단된 35예에 대해 의무기록을 이용하여 후향적으로 분석하였다. 결과: 28명에 대해 추적관찰이 가능하였고 이 중 17명은 생존 출생하였다. 22명의 태아에서 염색체검사를 시행하였으며 모두 정상 소견이었다. 12명 (34.2%)에서 동반기형이 발견되었다. 이 중 8명은 양막대증후군 (22.9%), 6명은 척추측만 (17.1%)이었고, 구개열, 태아수종, 뇌수종, 무뇌증은 각각 1명 (2.9%)이었다. 태아 치료를 위해 4명이 양수주입술과 양수교환술을 동시에 시행 받았다. 4명 (23.5%)이 제왕절개술로 분만되었다. 신생아들은 모두 출생 직후 외과적 치료를 받았다. 8명 (47.1%)에서 수술 후 합병증을 보였다. 3명은 사망하여 전반적인 생존율은 82.4%이었다. 영아의 평균 재원기간은 36일 (2~210일)이었다. 결론: 산전진단된 배벽갈림증은 외과적 치료의 예후가 좋고 전반적인 생존율도 높았다. 이러한 결과는 기존의 연구와 일치하고 있으며, 배벽갈림증으로 산전 진단 받은 산모를 상담하는데 도움을 줄 수 있을 것으로 기대된다. Objective: The aim of this study is to analyze the perinatal courses, fetal treatment and postnatal outcomes of fetal gastroschisis. Methods: A retrospective review of the medical records of 35 cases with a prenatal diagnosis of gastroschisis was conducted between March 1997 and April 2007. Results: Twenty-eight fetuses were followed up and 17 fetuses of them were born alive. Chromosomal study was performed in 22 fetuses and no abnormality was detected in them. Associated anomalies except for gastrointestinal anomalies were found in 12 (34.2%) cases: amniotic band syndrome (n=8), scoliosis (n=6), cleft lip (n=1), hydrops (n=1), hydrocephalus (n=1), acrania (n=1). In 4 fetuses, amnioinfusion and amnioexchange were performed simultaneously for treatment. Four cases (23.5%) were delivered by cesarean section. All neonates received corrected operation immediately after birth and 8 (47.1%) of them had postoperative complications. Three of them were died and the overall survival rate was 82.4%. The average length of hospital stays for the survivors was 36 days (2~210days). Conclusion: Fetal gastroschisis diagnosed prenatally has a good prognosis and high survival rates. The result of this study was not different from that of preexisting studies and will be a useful guide in counseling parents with a prenatal diagnosis of gastroschisis.

Mediastinal nodal staging of nonsmall cell lung cancer using integrated ¹⁸F-FDG PET/CT in a tuberculosis-endemic country : Diagnostic efficacy in 674 patients

Kim, Yoon Kyung,Lee, Kyung Soo,Kim, Byung-Tae,Choi, Joon Young,Kim, Hojoong,Kwon, O Jung,Shim, Young Mog,Yi, Chin A,Kim, Ha Young,Chung, Myung Jin Wiley Subscription Services, Inc., A Wiley Company 2007 Cancer Vol.109 No.6

<B>BACKGROUND</B><P>Integrated <SUP>18</SUP>fluorine fluorodeoxyglucose (<SUP>18</SUP>F-FDG) positron emission tomography/computed tomography (PET/CT) has shown somewhat variable sensitivity and specificity for mediastinal nodal staging in granulomatous disease endemic areas. The purpose of the study was to prospectively evaluate the efficacy of PET/CT for mediastinal nodal staging in nonsmall cell lung cancer (NSCLC) patients in a tuberculosis-endemic country.</P><B>METHODS</B><P>Prospective assessment of the diagnostic efficacy of integrated PET/CT for detecting mediastinal nodal metastasis was performed in 674 patients (M:F ratio = 502:172; mean age, 61 years) with NSCLC. Patients underwent an integrated PET/CT examination and subsequent surgical nodal staging (by mediastinoscopy only in 121 patients and by thoracotomy in 553). Nodes showing greater <SUP>18</SUP>F-FDG uptake than mediastinum at PET without benign calcification or high attenuation >70 household unit (HU) at unenhanced CT were regarded as being positive for malignancy. The histologic nodal assessment results were used as reference standards.</P><B>RESULTS</B><P>Of 2477 mediastinal nodal stations evaluated in 674 patients, 275 (11%) stations in 180 (27%) patients proved to be malignant. On a per-person basis, the overall sensitivity, specificity, and accuracy of PET/CT for mediastinal nodal staging were 61% (110 of 180), 96% (473 of 494), and 86% (583 of 674), respectively. On a per-nodal station basis, they were 46% (126 of 275), 98% (2154 of 2202), and 92% (2280 of 2477).</P><B>CONCLUSIONS</B><P>Integrated PET/CT provides high specificity and reasonably high accuracy, but somewhat low sensitivity for mediastinal nodal staging of NSCLCs. The high specificity is achieved at the expense of sensitivity by interpreting calcified nodes or nodes with high attenuation at CT, even with high FDG uptake at PET, as benign in a tuberculosis-endemic region.
