        필릿용접에서 리브높이에 따른 용접변형 해석에 대한 연구

        김용래,송규영,왕초,김재웅,Kim, Yong-Rae,Song, Gyu-Yeong,Wang, Chao,Kim, Jae-Woong 대한용접접합학회 2013 대한용접·접합학회지 Vol.31 No.6

        The welding distortion is caused by welding heat in the structures which are widely used in shipbuilding and automotive industries, thus many researchers have proposed such methods to control the welding distortion through trials and numerical studies. The welding distortion has been the main cause of low productivity due to the structural strength degradation, apparent flaw, additional deformation caused by the process followed the current assembly step, and the increase of correction workload. The deformation of fillet welding is investigated in this study, and the influence of the rib height on the welding distortion is verified through the actual experiment. And the numerical analysis model using the FE software MSC.marc for analysis of welding distortion is proposed.

        GTA 오버레이 용접부의 열유동 해석을 위한 용접열원 모델링

        김용래,채현병,김재웅,Kim, Yong-Rae,Chae, Hyunbyung,Kim, Jae-Woong 대한용접접합학회 2013 대한용접·접합학회지 Vol.31 No.4

        Overlay welding is carried out to improve the corrosion resistance, wear resistance and heat resistance on the surface of the chemical plant and steelmaking plant structures. In overlay welding, control of the bead size and the temperature distribution of weldment are particularly important because that is directly connected to the improvement of quality and productivity. The aim of this study is to model the welding heat source that is very useful to analyze the bead size and temperature distribution of weldment. To find the welding heat source model, numerical analyses are performed by using FE software MSC-marc.

        사업장 자체측정기관 국내 , 외 정도관리 참여 결과

        김용래,조기현,이영세,이송권,채종홍 한국산업위생학회 1995 한국산업보건학회지 Vol.5 No.1

        Since being granted permission for self-assessment of the work environment by the Department of Labor in 1992, POSCO's Industrial Hygiene Laboratory has participated in domestic and Foreign Quality Control Programs 8 times and has obtained remarkable results. It has made a lot of effort to be a proficient laboratory with the ability to observe and analyse environmental monitoring data. The summary of results is as follows: 1. POSCO's Industrial Hygiene Laboratory has received a $quot;P(Proficient)$quot; grade from the round 115 to round 119 of AIHA/NIOSH PAT Program for analysis of such metals as lead, cadmium, zinc, and chromium, and also has received a $quot;P(Proficient)$quot; grade from its round 119 of for organic solvent analysis, i,e,. Trichloroethyiene(TCE), Carbon Tetr-achloride(CTC), 1.2-Dichloroethane(DCE), 1,1,1-Trichloroethane(MCM), Tetrachloroethylene (PCE), Chloroform(CFM), Benzene(BNZ), toluene(TOL), and O-xylene(OXY). 2. In the Quality Control Evaluation Program performed by the Industrial Health Research Institute, Korea Industrial Safety Corporation, POSCO has passed impressively in the 3-metal analysis test for lead, cadmium, cupper, and in the 6 organic solvent analysis test for Benzene(BNZ), toluene(TOL), O-xylene(OXY), Trichloroethylene(TCE) and Methyl isobutyl keton(MIBK), n-Hexane with 2 standard deviations. These analytic techniques should be practically applied to various fields, and reliable results of environmental monitoring should be considered to improve the work environment and to keep workers from occupation related diseases.

        구조방정식 모형을 이용한 반부패 인식에 관한 연구 : 청탁금지법과 신입사원을 중심으로

        김용래 한국부패학회 2019 한국부패학회보 Vol.24 No.2

        This study analyzed the perception of anti-corruption through a structural equation model and how the efforts of our society, focusing on the anti-graft law and new employees, affect the fair society. First of all, the results of frequency analysis through questionnaires showed a high rate of perceived corruption in our society, with only 20% of positive responses to our efforts to establish the anti-graft law in a stable manner. Second, our society's efforts were having a positive effect on the perception of anti-graft law and the fair society, but had no effect on the corruption reporting system. Third, awareness of the anti-graft law was found to have a positive effect on the corruption reporting system. Fourth, the recognition of the anti-graft law and the corruption reporting system were found to have no effect on the fair society. This seems to be due to the negative perception and difficulty of internal reporting in our society as the new employees see it. Fifth, our society's efforts for stable settlement of the anti-graft law have a positive effect on the fair society, and the understanding of anti-graft law and the corruption reporting system have been shown to have a low influence on the fair society but indirect influence. According to the results of the study, our society should make more efforts such as promoting related systems for anti-corruption and introducing a systematic education system for the stable operation of the anti-graft law in the future, and especially, it seems necessary to create a social climate that anyone who reports corruption can be protected safely. This study is meaningful as an empirically analytic case of how much our society is trying to realize fair society through the recognition of anti-graft of new employees since the enactment of the anti-graft law. 본 연구는 반부패 인식에 대하여 청탁금지법과 신입사원을 중심으로 우리 사회의 노력이 반부패제도 이해와 공정사회에 어떠한 영향을 미치고 있는지 구조방정식을 통하여 분석하였다. 연구결과, 첫째, 설문항목을 통한 빈도분석 결과를 보면 청탁금지법을 안정적 정착을 위한 우리 사회의 노력이나, 공정사회에 대하여는 긍정적인 답변이 20%대로 우리사회에 대한 높은 부패인식률을 보이고 있었다. 둘째, 우리 사회의 노력은 청탁금지법의 인식도와 공정사회에 긍정적인 영향을 미치고 있었으나, 부패신고제도에는 아무런 영향을 미치지 않고 있었다. 셋째, 청탁금지법에 대한 인식도는 부패신고제도에 긍정적인 영향을 미치는 것으로 나타났다. 넷째, 청탁금지법의 인식도와 부패신고제도는 공정사회에 아무런 영향을 미치지 않는 것으로 나타났다. 이는 신입사원이 바라보는 우리사회에 부정적인 인식과 내부 신고의 어려움 등이 한 원인으로 보여진다. 다섯째, 청탁금지법의 안정적 정착을 위한 우리 사회의 노력은 공정사회에 긍정적인 영향을 미치며 청탁금지법 이해도와 부패신고제도는 공정사회에 낮은 영향력이지만 간접적인 영향을 미치는 것으로 나타났다. 위와 같은 연구결과를 보면 우리사회는 향후 청탁금지법의 안정적인 운영을 위하여 관련 제도 홍보와 체계적인 교육시스템 도입 등 더욱 노력해야 하며, 특히 안심하고 신고할 수 있는 사회적 풍토 조성이 필요해 보인다. 본 연구는 청탁금지법 시행이후 신입사원의 반부패 인식을 통하여 우리사회가 공정사회 실현에 얼마나 노력하고 있는지에 대한 실증분석 사례로 그 의의가 있다고 하겠다.

        The purpose of this examination was to find out the relationship among secondary school learners' self-efficacy, instructional motivation and school life-related coping. And in order to achieve the purpose of this examination sampled middle/high school learners in Seoul and other areas. The instruments used for the data collection were 「Self-efficacy Scale」 (Kim, A-Young, 1997), 「School Learning Motivation」 (Kim, Yong-Rae, 2000) and 「School Adjustment Scale」 (Kim, Yong-Rae, 2000). The collected data analysis were performed using SPSS/WIN(11.0V) program, and analysis Mean score(M), Standard Deviation(SD), Zero Order Correlation(r) and Multi-Regression Analysis All statistic values were tested by t-test and F-test in the significant level of p<05. And as for the major findings of this examination, 'self-efficacy', 'instructional motivation' and 'school life-related coping' were significantly positive correlation. And 'self-efficacy' and 'instructional motivation' were significantly positive influences on Korea secondary school learners' 'school life-related coping' respectively.
