The stress corrosion cracking(SCC) and hydrogen embrittlement cracking(HEC) characteristics of a weathering steel weldment were investigated in aerated acid-chloride solution. The electrochemical properties of weldment were investigated by polarization test and galvanic corrosion test. Weathering steel did not show passive behavior in the acid-chloride solution. Galvanic corrosion between the weld metal and the base metal was not observed because the base metal was anodic to the weld metal. The slow-strain-rate tests(SSRT0 were conducted at a constant strain rate o 7.87×{TEX}$10^{-7}${/TEX}/s at corrosion potential, and at potentiostatically controlled anodic and cathodic potentials. The weldment of weathering steel was susceptible to both anodic dissolution SCC and hydrogen evolution HEC.

최윤석,장태영,김태연 대한이비인후과학회 2006 대한이비인후과학회지 두경부외과학 Vol.49 No.7

Background and Objectives:Mitomycin-C is an antibiotic, antineoplastic agent that inhibits DNA and protein synthesis,and fibroblast proliferation. It has been successfully used in adjunction to glaucoma surgery, dacryocystorhinostomy, pterygium surgery, and middle meatal antrostomy. The purpose of this study is to evaluate the symptomatic improvement and the state of soft palate stenosis after intraoperative application of topical Mitomycin-C in surgical treatment of snoring. Subjects and Method:Forty-two patients (38 men, 4 women) undergoing laser-uvulopalatopharyngoplasty (Laser-UPPP) for snoring were included. The patients were operated on at the Inha University Hospital between May of 2003 and Oct. of 2004. The patients were divided into two groups in accordance with intraoperative application of topical Mitomycin-C in surgical treatment of snoring. The degree of snoring and apnea related symptoms and complication were evaluated using questionnaires preoperatively and postoperatively. We also evaluated and compared the degree of stenosis of soft palate postoperatively of each group. Results:After Laser-UPPP, significant differences were seen in the pre & postoperative symptom score (snoring, apnea, daytime sleepiness) of each group, but no significant differences were observed between groups. There was a significant improvement in the degree of stenosis of soft palate in the group with intraoperative application of topical Mitomycin-C. Significant differences were seen in the postoperative complication score (nasal regurgitation, foreign body sensation) in the experimental group. Conclusion:Intraoperative topical application of Mitomycin-C can be used as a beneficial adjunct therapy in the surgical treatment of snoring. (Korean J Otolaryngol 2006;49:706-10)

Relationship between Poor Immunogenicity of HLA-A2-Restricted Peptide Epitopes and Paucity of Naïve CD8+ T-Cell Precursors in HLA-A2-Transgenic Mice

최윤석,이동호,신의철 대한면역학회 2014 Immune Network Vol.14 No.4

We examined the immunogenicity of H-2 class I-restricted and HLA-A2-restricted epitopes through peptide immunization of HLA-A2-transgenic mice that also express mouse H-2 class I molecules. All four of the tested epitopes restricted by H-2 class I robustly elicited T-cell responses, but four of seven epitopes restricted by HLA-A2 did not induce T-cell responses, showing that HLA-A2-restricted peptide epitopes tend to be poorly immunogenic in HLA-A2-transgenic mice. This finding was confirmed in HLA-A2-transgenic mice infected with a recombinant vaccinia virus expressing hepatitis C virus proteins. We examined the precursor frequency of epitope-specific naïve CD8+ T cells in HLA-A2-transgenic and conventional C57BL/6 mice and found that the poor immunogenicity of HLA-A2-restricted peptide epitopes is related to the paucity of naïve CD8+ T-cell precursors in HLA-A2-transgenic mice. These results provide direction for the improvement of mouse models to study epitope repertoires and the immunodominance of human T-cell responses

In the modern management literature, knowledge has been recognized as a new strategic resource enabling a firm to create its competitiveness. Shipping companies under fierce competitive structure need to pay attentions to the utility of knowledge management. A shipping firm may develop its unique service capability by classifying, sharing, and transferring the data, information and knowledge obtained from both inside and outside its global service network. The current study attempts to analyze influential relationships between liner shipping firms’ knowledge management and service capabilities. In order to achieve this goal, this study designed a knowledge chain model measuring shipping companies’ knowledge management levels and tested its validity and reliability based on a total of 80 replied questionnaires from national and foreign liners. The empirical result presents that supportive and primary activities composing a knowledge chain could exert significant positive influences on the enforcement of shipping service capabilities. This research shows that the utility of knowledge management is adoptable in the maritime industry, and recommends that shipping firms should recognize strategic importance of knowledge and actively pursue knowledge management at an entire firm level.

서해연안 패류의 성분원소 함량 및 퇴적물의 지화학적 특성

최윤석,송재희,박광재,윤상필,정상옥,안경호 한국패류학회 2012 The Korean Journal of Malacology Vol.28 No.3

갯벌어장에 서식하는 패류의 성분원소 함량 및 연안 생태계의 퇴적물의 지화학적 특성의 연관성을 조사하기 위하여 서해연안을 연구지역으로 선정하였다. 연구지역내 갯벌어장 표층퇴적물의 COD, AVS, IL의 지화학적특성은 다소 오염된 지역이 나타나지만 대부분 양식장 오염니 기준에 비하여 매우 낮은 농도를 보이며 패류의 성장에영향이 적은 것으로 생각된다. 그리고 중금속에 대한 농축비(Ef) 와 농집지수 (Igeo) 의 결과는 연구지역이 오염원이 적은자연적인 상태를 유지하여 서식하는 패류에 대한 오염이 적은것으로 평가되었다. 또한 연구지역내에 서식하는 패류의 성분원소 함량을 분석한 결과에 따르면 퇴적물과 패류의 원소함유량의 상관관계는 연관성 있는 것으로 평가되었다. 패류의 무기원소 및 중금속의 농축은 Mn, Zn에 대해서만 상관관계가 반영되는 것으로 사료된다. 한편 갯벌어장의 패류 및 저서생물들이 서식하기에 좋은 조간대 퇴적물 상태를 유지하기 위하여 어장관리를 위한 중금속 오염에 대한 기준설정이 필요하며, 오염경로와 퇴적물의 오염원을 관리할 수 있는 체계적인 정책이 요구된다. In order to evaluate the relationship of between the contents of inorganic elements in shellfish and surface sediments, we measured the concentration of inorganic elements (As, Ca, Cd, Cr, Fe, Hg, Li, Mn, Ni, P, Pb, Zn) in various shellfish and surface sediments of research area. The enrichment factor (EF) and the index of accumulation rate (Igeo) of the metals showed that the research areas can be classified as moderately polluted, or unpolluted. And also we measured the geochemical characteristics of surface sediments(grain size, chemical oxygen demand (COD), ignition loss (IL) and acid volatile sulfide (AVS). The grain sizes for research areas of surface sediment were similar the ratio of silt and clay in comparison with other sites. The COD and IL in surface sediment ranged from 5.41 to 14.06 mg/g. d.w. (mean 8.78 ± 3.16 mg/g d.w.) and from 0.92 to 3.17% (mean 2.08 ± 0.86%), respectively. Siginificant differences in metal concentrations also were determinated in the shellfish tissue among the different sites. However, except for metals(Mn, Zn), which showed some elevation of concentrations, the variations in the shellfish tissue were not related to variations in the sediment.
