Background: Hepatic epithelioid hemangioendothelioma (HEH) is a rare tumor of vascular origin with an unknown etiology, a low incidence, and a variable natural course. We evaluated the management and prognosis of HEH from the Surveillance, Epidemiology and End Results (SEER) program and changes in treatment modalities of HEH over 30 years. Methods: From 1973 to 2014 in the SEER database, we selected patients diagnosed with HEH. We analyzed the clinical characteristics, patterns of management, and clinical outcomes of patients with HEH. Results: We identi ed 79 patients with HEH (median age: 54.0 years;male to female ratio: 1:2.6). The initial extent of disease was local in 22 (27.8%) patients, regional metastasis in 22 (27.8%), distant metas-tasis in 31 (39.2%) and unknown in 4 (5.1%). The median size of primary tumor was 3.85 cm (interquartile range, 2.50 7.93 cm). Among 74 patients with available management data, the most common manage-ment was no treatment (29/74, 39.2%), followed by chemotherapy only (22/74, 29.7%), liver resection-based (13/74, 17.6%), and transplantation-based therapy (6/74, 8.1%). The 5-year cancer-speci c survival rate was 57.8%. Patients who underwent surgical treatment had signi cantly higher survival than those who underwent non-surgical treatment (5-year survival;88% vs. 49%, P=0.019). Multivariate analysis revealed that surgical therapy was the only independent prognostic factor for survival (hazard ratio: 0.20, P=0.040). Conclusions: Resection or liver transplantation is worth considering for treatment of patients with HEH.

Evaluation of non-ampullary duodenal polyps: Comparison of non-neoplastic and neoplastic lesions

引用

World Journal of Gastroenterology 2010年第43期16卷 5474-5480页

作者： Sung Hoon jung Woo Chul Chung Eun jung Kim Seol Hye Kim Chang Nyol Paik Bo In Lee Young Seok cho Kang-Moon Lee Department of Internal Medicine College of Medicine The Catholic University of Korea

AIM: To evaluate duodenal polyps, divided into nonneoplastic and neoplastic lesions. In addition, the clinical characteristics of duodenal hyperplastic polyps are determined. METHODS: We analyzed medical records of 50 114 consecutive patients submitted to for first diagnostic esophago-gastroduodenoscopy between January 2004 and December 2009. We excluded lesions on the ampulla of Vater and submucosal tumors. We studied 510 cases that were diagnosed endoscopically with duodenal polyps and enrolled a total of 221 cases that had undergone tissue biopsy. We analyzed the differences between non-neoplastic and neoplastic lesions, and determined the clinical features of duodenal hyperplastic polyps. RESULTS: Non-neoplastic lesions were found in 196 patients and neoplastic lesions in 25 patients. On uni-variate analysis, there were significant differences in shape, location, and size. Polyps more than 10 mm in diameter or polyps in the second portion had independent risk factors for being neoplastic lesions, as identified by multivariate analysis. In 23 cases of hyperplastic polyps (79.3%), they were accompanied by gastroduodenal pathology, which was possibly associated with Helicobacter pylori . CONCLUSION: Polyps of more than 10 mm or polyps in the second portion of the duodenum should be evaluated by histological examination.

Inferring community properties of benthic macroinvertebrates in streams using Shannon index and exergy

Frontiers of Earth Science 2014年第1期8卷 44-57页

作者： Tuyen Van NGUYEN Woon-Seok cho Hungsoo KIM Il Hyo jung YongKuk KIM Tae-Soo choN Department of Mathematics Pusan National University Busan 609-735 Korea Department of Biological Sciences Pusan National University Busan 609-735 Korea DSPENALO National Robotics Research Center Pusan National University Busan 609-735 Korea Department of Mathematics Kyungpook National University Daegu 702-701 Korea

Definition of ecological integrity based on community analysis has long been a critical issue in risk assessment for sustainable ecosystem management. In this work, two indices （i.e., Shannon index and exergy） were selected for the analysis of community properties of benthic macroinvertebrate community in streams in Korea. For this purpose, the means and variances of both indices were analyzed. The results found an extra scope of structural and functional properties in communities in response to environmental variabilities and anthropogenic disturbances. The combination of these two parameters （four indices） was feasible in identification of disturbance agents （e.g., industrial pollution or organic pollution） and specifying states of communities. The four-aforemen- tioned parameters （means and variances of Shannon index and exergy） were further used as input data in a self- organizing map for the characterization of water quality. Our results suggested that Shannon index and exergy in combination could be utilized as a suitable reference system and would be an efficient tool for assessment of the health of aquatic ecosystems exposed to environmental disturbances.

Driving characteristics of octagon-type ultrasonic motor

引用

Journal of Central South University 2013年第1期20卷 71-75页

作者： KIM Jong-wook PARK choong-Hyo LIM jung-Hoon JEONG Seong-Su PARK Jong-Kyu PARK Tae-Gone Changwon National University Sarim-dongChangwon-siGyeongsangnam-do641-773Korea

Structure of the octagon-type ultrasonic motor was proposed and designed so as to allow the motor to drive small actuator. The stator of the motor consisted of the octagon shape elastic body and four rectangular plate ceramics. The four ceramics were attached to outer surfaces of the octagon elastic body. The same phase voltages were applied to the ceramics on horizontal surfaces, and 90° phase difference voltages were applied to the ceramics on vertical surfaces. When the AC voltage with 90° phase difference was applied in ceramics, the elliptical displacement of unimorph bars was generated by generating bending vibration. To find the maximum displacement model that generates elliptical displacement at the centers of the inner surfaces, the finite element analysis program ATILA was used. The analyzed results were compared to the experimental results. As a result, the speed and torque are increased linearly by increasing the input voltage and the speed of motors can be controlled by changing the applied voltages.
