Steel applied in ocean environment is exposed to corrosion and cavitation and is subject to increasing damages. To prevent this, anti-corrosion thermal spray coating technique is widely used. The low-temperature thermal spray coating was performed with 85%Al-14.5%Zn-0.5%Zr for ship materials and various sealing materials were applied to improve its durability, and the electrochemical behavior and cavitation characteristics were observed. The results show that the sealing improves all the properties of the materials. Hybrid ceramic and fluoro-silicon sealing materials show good electrochemical characteristics, and the fluoro-silieon sealing material shows the best anti-cavitation characteristics.

Simultaneous laparoscopic multi-organ resection combined with colorectal cancer:Comparison with non-combined surgery

World Journal of Gastroenterology 2012年第8期18卷 806-813页

作者： Hye Jin Kim Gyu-Seog Choi Jun seok Park Soo Yeun Park Soo han Jun Department of Surgery Kyungpook National University Hospital School of Medicine Kyungpook National University Department of Surgery Daegu Catholic Medical Center Catholic University of Daegu

AIM: To access the short-term outcomes of simultaneous laparoscopic surgery combined with resection for synchronous lesions in patients with colorectal cancer. METHODS: Between March 1996 and April 2010 prospectively collected data were reviewed from 93 consecutive patients who had colorectal cancer and underwent simultaneous multiple organ resection (combined group) and 1090 patients who underwent conventional laparoscopic right hemicolectomy or laparoscopic low/ anterior resection for colorectal cancer (non-combined group). In the combined group, there were nine gastric resections, three nephrectomies, nine adrenalectomies, 56 cholecystectomies, and 21 gynecologic resections. In addition, f ive patients underwent simultaneous laparoscopic resection for three organs. The patient demographics, intra-operative outcomes, surgical morbidity, and short-term outcomes were compared between thetwo groups (the combined and non-combined groups). RESULTS: There were no signifi cant differences in the clinicopathological variables between the two groups. The operating time was signifi cantly longer in the combined group than in the non-combined group, regardless of tumor location (laparoscopic right hemicolectomy and laparoscopic low/anterior resection groups; P = 0.048 and P < 0.001, respectively). The other intraoperative outcomes, such as the complications and open conversion rate, were similar in both groups. The rate of post-operative morbidity in the combined group was similar to the non-combined group (combined vs non-combined, 15.1% vs 13.5%, P = 0.667). Oncological safety for the colon and synchronous lesions were obtained in the combined group. CONCLUSION: Simultaneous laparoscopic multiple organ resection combined with colorectal cancer is a safe and feasible option in selected patients.

World Journal of Gastroenterology 2016年第14期22卷 3785-3792页

作者： Yun Soo Hong Dong Hyun Sinn Geum-Youn Gwak Juhee Cho Danbee Kang Yong-han Paik Moon seok Choi Joon Hyeok Lee Kwang Cheol Koh Seung Woon Paik Department of Medicine Samsung Medical Center Sungkyunkwan University School of Medicine Department of Health Sciences and Technology SAIHST Sungkyunkwan University Deaprtment of Health Behavior and Society and Epidemiology Johns Hopkins Bloomberg School of Public Health

AIM: To analyze characteristics and outcome of patients with acute-on-chronic liver failure(ACLF) according to the severity of underlying liver disease. METHODS: One hundred and sixty-seven adult patients with chronic liver disease and acute deteriorated liver function, defined by jaundice and coagulopathy, were analyzed. Predisposition, type of injury, response, organ failure, and survival were analyzed and compared between patients with non-cirrhosis(type A), cirrhosis(type B) and cirrhosis with previous decompensation(type C).RESULTS: The predisposition was mostly hepatitis B in type A, while it was alcoholic liver disease in typesB and C. Injury was mostly hepatic in type A, but was non-hepatic in type C. Liver failure, defined by CLIF-SOFA, was more frequent in types A and B, and circulatory failure was more frequent in type C. The 30-d overall survival rate(85.3%, 81.1% and 83.7% for types A, B and C, respectively, P = 0.31) and the 30-d transplant-free survival rate(55.9%, 65.5% and 62.5% for types A, B and C, respectively P = 0.33) were not different by ACLF subtype, but 1-year overall survival rate were different(85.3%, 71.7% and 58.7% for types A, B and C, respectively, P = 0.02).CONCLUSION: There were clear differences in predisposition, type of injury, accompanying organ failure and long-term mortality according to spectrum of chronic liver disease, implying classifying subtype according to the severity of underlying liver disease is useful for defining, clarifying and comparing ACLF.
