Endoscopic submucosal dissection is an effective treatment modality for early gastric cancer(EGC), though the submucosal fibrosis found in ulcerative EGC is an obstacle for successful treatment. This report presents two cases of ulcerative EGC in two males, 73- and 80-year-old, with severe fibrosis. As endoscopic ultrasonography suggested that the EGCs had invaded the submucosal layer, the endoscopic submucosal tunnel dissection salvage technique was utilized for complete resection of the lesions. Although surgical gastrectomy was originally scheduled, the two patients had severe coronary heart disease, and surgeries were refused because of the risks associated with their heart conditions. The endoscopic submucosal tunnel dissection salvage technique procedures described in these cases were performed under conscious sedation, and were completed within 30 min. The complete en bloc resection of EGC using endoscopic submucosal tunnel dissection salvage technique was possible with a free resection margin, and no other complications were noted during the procedure. This is the first known report concerning the use of the endoscopic submucosal tunnel dissection salvage technique salvage technique for treatment of ulcerative EGC. We demonstrate that endoscopic submucosal tunnel dissection salvage technique it is a feasible method showing several advantages over endoscopic submucosal dissection for cases of EGC with fibrosis.

Endurance Analysis of Automotive Vehicle’s Door W/H System Using Finite Element Analysis

引用

Journal of Software Engineering and Applications 2009年第5期2卷 375-382页

作者： Byeong-Sam kim Kyoungwoo Park young-Woo kim 不详

In the automotive electronics industry, demand for low-cost, high strength-to in-service performance for electronic components continues to drive the development of vehicles’ door Wiring Harness (W/H) system for new applications. The problem of the fatigue strength estimation of materials or components containing natural defects, inclusions or in homogeneities is of great importance from both a scientific and industrial point of view. This article gives some insight into the dimensioning process, with special focusing on fatigue analysis of W/H in a vehicle’s door structures. An en-durance life prediction of door W/H was calculated using finite element analyses. Endurance test data for slim test specimens were compared with the predicted fatigue life for verification. The final life expectancy of the component combines the effects of these microstructural features with the complex stress state arising from the combined service loading and residual stresses.

The purpose of this study was to evaluate the effect of pelvic exercise on standing balance in patients with incomplete cervical spinal cord injury for healthy rehabilitation. 11 patients (8 men and 3 women) with levels of incomplete injury between cervical 3 and cervical 6 who were participated in a study measuring the standing balance using an interactive balance system (IBS) before and after pelvic exercise. The index of standing balance after pelvic exercise was significantly lower than before exercise in patients with incomplete cervical cord injury. The greatest improvements were observed in incomplete cervical spinal cord injury with neurologic levels of cervical 3 and 4 with Brown-Sequard syndrome. These results suggest that the pelvic exercise for rehabilitation significantly improved in part standing balance in patients with incomplete cervical spinal cord injury.

第五届国际材料与热加工物理模拟及数值模拟学术会议

作者： Kwang Ryul kim Kwang Ho kim National Core Research Center for Hybrid Materials Solution Pusan National University Busan 609-735 South Korea National Core Research Center for Hybrid Materials Solution Pusan National University Busan 609-735 South Korea

A mathematical model of the dynamics of laser-produced heating, evaporation and plume formation is presented. The condensed material model includes conduction heat transfer as well as melting and evaporation phase changes. The localized heating and evaporation caused by focused laser radiation forms a plume of mixed vapor above the material surface. The beam is absorbed and refracted as it traverses the plume, thus modifying its power density on the surface. In this work, variations of heat transfer rate during laser heating and effects of a plume formed by vapor from an iron surface are studied using an axisymmetric mass, momentum and energy transport model. The simulation results quantify the heat transfer rate in the plasma plume, heat losses due to radiation, and variations of heat input into the material.

WHEN looking at China＇s 12th Five-year Plan （2011-15） we observe that the country has singled out several industries, such as new energy resources and biotechnology, and has expressed its aspiration to support related businesses in order to compete on a global scale. It seems that China＇s effort has turned out positively in some areas. These efforts were based on unprecedented growth rates for the last three decades, which might now be a matter of the past. yet, meanwhile China has transformed itself from a country that copies Western and other Asian competitors to one that has the most number of patent filings worldwide. Based on this experience.

Prediction of forming limit curve for pure titanium sheet

引用

Transactions of Nonferrous Metals Society of China 2018年第2期28卷 319-327页

作者： young-Suk kim Bong-Hyun LEE Seung-Han yANG School of Mechanical Engineering Kyungpook National University Daegu-Gyeongbuk Center Korea Automotive Technology Institute

Commercially pure titanium（CP Ti） has been actively used in the plate heat exchanger due to its light weight, high specific strength, and excellent corrosion resistance. However, researches for the plastic deformation characteristics and press formability of the CP Ti sheet are not much in comparison with automotive steels and aluminum alloys. The mechanical properties and hardening behavior evaluated in stress-strain relation of the CP Ti sheet are clarified in relation with press formability. The flow curve denoting true stress-true strain relation for CP Ti sheet is fitted well by the kim-Tuan hardening equation rather than Voce and Swift models. The forming limit curve（FLC） of CP Ti sheet as a criterion for press formability was experimentally evaluated by punch stretching test and analytically predicted via Hora＇s modified maximum force criterion. The predicted FLC by adopting kim-Tuan hardening model and appropriate yield function shows good correlation with the experimental results of punch stretching test.
