Journal of Cancer Therapy 2013年第1期4卷 323-330页

作者： jae Do Kim Tae hun Kim So Hak Chung Department of Orthopedic Surgery Kosin University Gospel Hospital Busan Korea

Purpose: This study analyzed oncological and functional outcomes of treatment for Ewing’s sarcoma, as well as its significant risk factors through long-term follow up. Objective and Method: Between September 1990 and April 2009, 20 cases that were diagnosed and treated as Ewing’s sarcoma in Kosin University Gospel Hospital were entered onto the study. Mean follow-up period was 45.4 (12 - 108) months. There were 7 cases of male and 13 cases of female, and mean age was 19.9 (5 - 48) years old. Retrospective review was done about treatment outcomes, complications, and significant risk factors. Results: In terms of oncologic results, there were 9 cases of CDF (continuous disease free), 1 case of NED (no evidence of disease), 4 cases of AWD (alive with disease), 5 cases of DOD (dead of disease), and 1 case of DWOD (dead with other disease). Five-year overall survival rate of all the patients was 70.0% and event-free survival rate was 50.0%. The mean MSTS (Musculoskeletal Tumor Society) score was 15.9 (53%) points at last follow-up. Among prognostic factors of age at diagnosis, Enneking stage, size of tumor, site of primary lesion, and distant metastasis, 5-year survival rate of groups without metastasis were 90.9%, nevertheless 44.4% in other group with the metastasis showing statistical significance (p = 0.020). Postoperative complications were 3 cases of infection, each 2 cases of ankylosis and metal failure, and each 1 case of leg length discrepancy, periprosthetic fracture, and local recurrence. Conclusion: Five-year survival rate of this study was similar to that of multicenter studies in America and Europe. Among the prognostic factors, distant metastasis was proven to be most significant. Enneking stage, size of tumor and site of primary lesion are also important and could be statistically significant if with more cases.

作者： Jeong Suh jae-Hoon lee Hie-Sin Kang Kyoung-Taik Park Moon-Yong lee Byung-hun Jung Korea Institute of Machinery & Materials Technical Institute of Sungwoo Hitech Co. LTD

To minimize the weld defect in manufacturing the welded tube by using CO2 laser, the monitoring of the welding quality and the seam tracking along the butt-joint lengthwise to the tube axis are studied. The tube, 60kgf/mm2grade steel sheet, is formed by 2 roll bending machine. The tube has the thickness 1.5mm, diameter 105.4mm and length 2000mm. The longitudinal butt-joint of the tube is welded by the CO2 laser welding system equipped with the seam tracker and plasma *** precise positioning (<200μm) of the laser beam on the butt-joint to be assembled is obtained by the seam tracker with MVS-5 sensor (combination of laser emitter and CCD camera). The artificial defects (<φ1mm) in the butt-joint are well observed by the signal of plasma intensity measured by the plasma sensor of UV wavelength range (<400nm). The developed CO2 laser tube welding system has the function of the precision seam tracking and the real-time monitoring of the welding quality. Finally, the laser welded tube can be used for manufacturing of automobile chassis and components after tubular hydro-forming.

Efficiency Improvement of 590 nm AIGalnP Light Emitting Diode with a Reflective Top Electrode

引用

Journal of Physical Science and Application 2014年第2期4卷 115-118页

作者： Hyung Joo lee Young Dae Cho Young Jin Kim Choong hun lee jae Hoon Kim Hwa Sub Oh Su Chang Ahn CF Technology Division AUK Corporation lksan 570-210 Republic of Korea Division of Microelectronics and Display Technology Wonkwang University Iksan 570-749 Republic of Korea LED Team Korean Photonic Technology Institute (KOPTI) Gwangfu 500-779 Republic of Korea

In this work, enhancement of the light extraction efficiency of a 590 nm AIGaInP light-emitting diodes （LED） with a reflective top electrode （RTE） was investigated. A distributed Bragg reflector （DBR）, consisting of AIAs/AIGaAs pairs, grown on an AlGaInP structure was used as a reflector for a reflective top electrode. It was found that a higher output power was observed from the AIGalnP LED with a RTE than from a conventional one. In addition, it was noted that the improvement in the output power depends strongly on the reflectivity of the reflector and that it exhibits a more effective performance with low injection currents. The increase in the optical output power was attributed to the enhanced extraction efficiency caused by a reduction of light absorbed from the emission region to top electrode through the RTE.

作者： Sang hun Shin Young Beom Song Mingeon Kim Hye Jin Kim Wook jae Yoo Kyoung Won Jang Bongsoo lee School of Biomedical Engineering BK21 Plus Research Institute of Biomedical Engineering Konkuk University Chungju-si Korea School of Energy Systems Engineering Chung-Ang University Seoul Korea

In this study, we fabricated a Cerenkov fiber-optic dosimeter (CFOD) without any scintillator to measure Cerenkov radiation signals owing to gamma-rays. The relative depth dose (RDD) distributions of Ir-192 HDR brachytherapy source were obtained by using the CFOD based on a subtraction method and the RDD curve was compared with the simulation result of Monte Carlo N-particle extended transport code (MCNPX). Finally, we demonstrated that the CFOD can be used to measure real-time dose information for HDR brachytherapy.

AIM To assess the performance of proposed scores specific for acute-on-chronic liver failure in predicting shortterm mortality among patients with alcoholic *** We retrospectively collected data from 264 patients with clinically diagnosed alcoholic hepatitis from January to December 2013 at 21 academic hospitals in Korea. The performance for predicting short-term mortality was calculated for Chronic Liver FailureSequential Organ Failure Assessment(CLIF-SOFA), CLIF Consortium Organ Failure score(CLIF-C OFs), Maddrey'sdiscriminant function(DF), age, bilirubin, international normalized ratio and creatinine score(ABIC), Glasgow Alcoholic Hepatitis Score(GAHS), model for end-stage liver disease(MELD), and *** Of 264 patients, 32(12%) patients died within 28 d. The area under receiver operating characteristic curve of CLIF-SOFA, CLIF-C OFs, DF, ABIC, GAHS, MELD, and MELD-Na was 0.86(0.81-0.90), 0.89(0.84-0.92), 0.79(0.74-0.84), 0.78(0.72-0.83), 0.81(0.76-0.86), 0.83(0.78-0.88), and 0.83(0.78-0.88), respectively, for 28-d mortality. The performance of CLIF-SOFA had no statistically significant differences for 28-d mortality. The performance of CLIF-C OFs was superior to that of DF, ABIC, and GAHS, while comparable to that of MELD and MELD-Na in predicting 28-d mortality. A CLIF-SOFA score of 8 had 78.1% sensitivity and 79.7% specificity, and CLIF-C OFs of 10 had 68.8% sensitivity and 91.4% specificity for predicting 28-d *** CLIF-SOFA and CLIF-C OF scores performed well, with comparable predictive ability for short-term mortality compared to the commonly used scoring systems in patients with alcoholic hepatitis.

A Study on Transmission Loss Characteristics of Honeycomb Panel for Offshore Structures

引用

Journal of Applied Mathematics and Physics 2015年第2期3卷 172-176页

作者： jae-Deok Jung Suk-Yoon Hong Jee-hun Song Hyun-Woung Kwon Department of Naval Architecture and Ocean Engineering Seoul National University Seoul Republic of Korea Department of Naval Architecture and Ocean Engineering Chonnam National University Yeosu Republic of Korea Department of Naval Architecture and Ocean Engineering Koje College Koje Republic of Korea

Honeycomb panel is consisted of 3 layers that are double-faced sheets and honeycomb-shaped core. It is highly desirable for ship, railway, and aerospace industry. The reason is that honeycomb panel excels in strength and in its weight. However in terms of insulation, it is a little bit insufficient to commonly use sandwich-panel. In this paper, Moor’s theory is used to predict sound transmission loss (STL). The theory is assumed that core layer is homogeneous orthotropic. And to calculate STL, it is evaluated in terms of the symmetric and anti-symmetric panel impedances, and the characteristic impedance of air. After that predicted data are compared with experiment data.

Background： Glehnia littoralis has been used for traditional Asian medicine, which has diverse therapeutic activities. However, studies regarding neurogenic effects of G. littoralis have not yet been considered. Therefore, in this study, we examined effects of G. littoralis extract on cell proliferation, neuroblast differentiation, and the maturation of newborn neurons in the hippocampus of adult mice. Methods： A total of 39 male ICR mice （12 weeks old） were randomly assigned to vehicle-treated and 100 and 200 mg/kg G. littoralis extract-treated groups （n = 13 in each group）. Vehicle and G. littoralis extract were orally administrated for 28 days. To examine neurogenic effects ofG. litmralis extract, we performed immunohistochemistry tbr 5-bromo-2-deoxyuridine （BrdU, an indicator for cell proliferation） and doublecortin （DCX, an immature neuronal marker） and double immunofluorescence staining for BrdU and neuronal nuclear antigen （NeuN, a mature neuronal marker）. In addition, we examined expressional changes of brain-derived neurotrophic factor （BDNF） and its major receptor tropomyosin-related kinase B （TrkB） using Western blotting analysis. Results： Treatment with 200 mg/kg, not 100 mg/kg, significantly increased number of BrdU-immunoreactive （＋） and DCX＋ cells （48.0 ±3.1and 72.0 ± 3.8 cells/section, respectively） in the subgranular zone （SGZ） of the dentate gyrus （DG） and BrdU＊/NeuN＋ cells （17.0 ±1.5 cells/section） in the granule cell layer as well as in the SGZ. In addition, protein levels of BDNF and YrkB （about 232% and 244% of the vehicle-treated group, respectively） were significantly increased in the DG of the mice treated with 200 mg/kg ofG. littoralis extract. Conclusion： G. littoralis extract promots cell proliferation, neuroblast differentiation, and neuronal maturation in the hippocampal DG, and neurogenic effects might be closely related to increases ofBDN F and TrkB proteins by G. littoralis extract treatment.
