Vanadium 을 첨가한 고장력강의 기계적 성질에 관한 연구

김용규,김상주,이후철,윤종규 대한금속재료학회(대한금속학회) 1979 대한금속·재료학회지 Vol.17 No.3

본 실험은 Vanadium의 첨가량과 소려온도의 변화에 따른 저탄소 Vanadium강의 기계적 성질의 변화를 조사한 것이다. Vanadium첨가량은 0∼0.16%까지 변화시켜 보았으며, 그 결과 0.106%까지는 첨가량이 증가할수록 경도, 인장강도, 항복강도, 내마멸성 등이 개선되였으나 0.16%에서는 기계적 성질이 더 이상 개선되지 않았다. 또한 소려온도는 500℃, 600℃, 700℃로 변화시켰으며, 기계적 성질은 600℃에서 가장 좋았다. 소입 및 소려된 Vanadium강에서의 Vanadium 탄화물의 석출은 전위 및 폐라이트 기지 내에 불규칙하게 분포되어 있었으며 기계적 성질의 개선은 이들 탄화물에 의한 입자의 미세화 및 전위의 고착, 전위 이동의 방해 등에 기인되는 것으로 보여진다. Effect of vanadium contents and tempering temperature on the mechanical properties of low carbon vanadium steel was studied with V content ranging from zero to 0.16% and tempering temperature of 500℃, 600℃ and 700℃. As the results, hardness, tensile strength, yield strength and wear resistance were increased with the increase of vanadium content and the maximum value was shown when 0.106% of vanadium was added and tempered at 600℃ for 1 hr. Vanadium carbides were dispersed in ferrite and randomly precipitated at dislocation sites. The improvement of the mechamical properties was interpreted in terms of grain refinement and locking of dislocations due to vanadium carbides.

미셀 푸코의 권력모델의 변화와 비판의 의미 : 전쟁에서 통치성으로

김용규 대동철학회 2018 大同哲學 Vol.85 No.-

이 글은 1976년부터 1979년까지 푸코의 콜레주 드 프랑스 강의록을 통해 ‘전쟁에서 통치성으로’ 나아가는 그의 권력이론의 변화를 검토하는 데 목적이 있다. 더 구체적으로 말해, 이 글은 1976년 성의 역사 제1권과 1984년 성의 역사 2, 3권 사이에 있었던 일련의 전환들, 즉 규율권력에서 생명권력으로의 전환(감시와 처벌에서 앎의 의지와 사회를 보호해야 한다까지), 생명권력에서 통치성 연구(사회를 보호해야 한다에서 안전, 영토, 인구와 생명정치의 탄생까지)로의 전환, 신자유주의적 통치성 연구에서 자아의 윤리로의 전환(79년부터 84년까지의 강의록과 쾌락의 활용, 자기배려) 중에서 두 번째 전환에 초점을 두고 푸코의 권력이론의 변화를 추적하고자 한다. 이 전환은 푸코의 권력이론의 발전에서 매우 중요한 연결고리로 기능한다. 그것은 규율권력과 생명권력을 안전권력과 자유주의적 통치성이라는 보다 확장된 문제틀 속으로 편입시키는 한편, 신자유주의적 통치성과 자기테크놀로지를 넘어 자기수양과 자기배려의 문제틀로 넘어가는 중간 단계를 이루고 있기 때문이다. 특히 이 전환은 푸코 자신의 이론 활동의 변화뿐만 아니라 프랑스의 정치현실과 관련된 지성계 내부의 변화를 반영하고 있다. 이 시기에 푸코는 68년 혁명 이후에 실천적으로 개입했던 사회적 실천투쟁에서 함께 했던 급진 좌파들과 맑스주의로부터 거리를 두는 한편 자유주의에 보다 많은 관심을 기울인다. 이 글은 이런 변화들을 고려하면서 ‘전쟁에서 통치성으로’라는 변화해가는 푸코의 권력이론의 전환을 분석하고자 한다. This paper aims to critically examine the change of Michel Foucault’s power theory “from war to governmentality” in the College de France lectures from 1976 to 1979. In that period, Foucault had attempted to change his own conception of power from discipline to bio-power, from bio-power to governmentality, and from neoliberal governmentality to the ethics of self. This paper focuses on the second change in order to track the change of power theory in Foucault. This change serves as a very important link in the development of Foucault's power theory. It not only incorporates disciplinary power and bio-power into a more expanded problematic of security power and liberal governmentality but also serves as an important stage for shifting beyond neoliberal governmentality and technologies of self into self-care and self-cultivation. In particular, this shift reflects the changes in the intellectual and political area in France as well as in Foucault's own theoretical practices. In that time, Foucault started to be more interested in liberalism while distanced from radical leftists and Marxists, who had together participated with Foucault in the social struggles since the ’68 Revolution. Considering these changes, this paper tries to grasp the turn “from war to governmentality” in the development of Foucault’s power theory.

A Study on the Profile Change Measurement of Steam Generator Tubes with Tube Expansion Methods

김용규,송명호,최명식 한국비파괴검사학회 2011 한국비파괴검사학회지 Vol.31 No.5

Steam generator tubes for nuclear power plants contain the local shape transitions on their inner or outer surface such as dent, bulge, over-expansion, eccentricity, deflection, and so on by the application of physical force during the tube manufacturing and steam generator assembling and by the sludge (that is, corrosion products) produced during the plant operation. The structural integrity of tubes will be degraded by generating the corrosive crack at that location. The profilometry using the traditional bobbin probes which are currently applied for measuring the profile change of tubes gives us basic information such as axial locations and average magnitudes of deformations. However, the three-dimensional quantitative evaluation on circumferential locations, distributional angle, and size of deformations will have to be conducted to understand the effects of residual stresses increased by local deformations on corrosive cracking of tubes. Steam generator tubes of Korean standard nuclear power plants expanded within their tube-sheets by the explosive expansion method and suffered from corrosive cracks in the early stage of power operation. Thus, local deformations of steam generator tubes at the top of tube-sheet were measured with an advanced rotating probe and a laser profiling system for the two cases where the tubes expanded by the explosive expansion method and hydraulic expansion. Also, the trends of eccentricity, deflection, and over-expansion of tubes were evaluated. The advanced eddy current profilometry was confirmed to provide accurate information of local deformations compared with laser profilometry.

김용규 한국체육정책학회 2020 한국체육정책학회지 Vol.18 No.1

The purpose of this study was to analyze the physical education subjects for student with disability at D university. The subjects gathered through purposive sampling were 4 students with disability who participated in the physical education subjects for student with disability and 2 staffs of D university. Collected Data were analyzed through literature analysis and a survey form semi-structured based on the researchers' opinion and referred to during the in-depth interview. The findings are as follows: first, historical particularity of D university effected on developing physical education subject for students with disability. Second, experience of participants on physical education subject was analyzed. Third, there was some inconvenience in physical education subject for students with disability. Lastly, it drew way to improve the physical education subject for students with disability. Finally, university had to provide high quality physical education for students with disability because of university enrollment rate of student with disability is increasing so university should strive to provide physical education subjects that take into account the specificity of students with disability.

스튜어트 홀과 영국 문화연구의 형성

김용규 새한영어영문학회 2007 새한영어영문학 Vol.49 No.1

This paper tries to provide a critical overview of Stuart Hall's cultural theory. Stuart Hall is being considered a figure who embodies a living history in British cultural studies, as Terry Eagleton says, "he is a kind of walking chronicle of everything from the New Left to New Times, Leavis to Lyotard, Aldermaston to ethnicity." It means not merely that Hall is one of the representative figures in the British New Left but that he is a controversial one who has continuously intervened in the British intellectual debate since the late 1950s and formed a tradition of the British New Left and cultural studies. So his theoretical trajectories can serve as a map of the history of the postwar British cultural left. The most important characteristics of his cultural theory lies in the fact that he has focused upon the contemporary and new cultural phenomena emerging in the postwar British society. His senior theorists, such as E. P. Thomson, Raymond Williams and Richard Hoggart, paid attention to the cultural aspects of British society but their emphasis was upon the popular culture or experience which disappeared with the advent of the mass culture. But Hall gives above all priority to the newly emerging cultural phenomena. This paper tries to examine how Hall's emphasis on the new or the contemporary is shaped and what influence it gives on his later theoretical developments.
