J.Lacan 과 여성학

송동건 이화여대 한국여성연구소 1987 여성학논집 Vol.4 No.-

As late as 1980 New Yorker magazine reports that among American psychoanalytic circle the French structuralist psychoanalyst, Jacques Lacan, "Whose impenetably obscure writings" have been gaining increasingly earnest attention. It was the next year that Lacan died. It would be more accurate to say that Lacan's long obscurity in English-speaking world has been due largely to his anti-reductionist stance rather than his rather idiosyncratic rhetoric style. What is at stake for waging the attrition war between the Continent and the Anglo-American psychoanalyst was the enormous Empire of International Psycoanalytic Association with Anna Freud at its apex. Equally important, or in a sense more so, is, as Freud himself anticipated, which side of the Ocean would win "the decisive battle" for the real carrier of Freudian messages. In other words whether psychoanalysis is a biological science or cultural science is the real issue. And neither side can afford to give in to the other not merely because of vast vested interest for the positive camp, but also the very foundation of their trade itself is challenged with the long celebrated Freudian topographies in the danger of revision. This explains why the great interest in and serious reception of Lacan after his death have been mostly in the fields other than psychoanalysis itself. After 1981 books and articles are pouring in about Lacan. His most appealing contribution, though its full appreciation is yet to be seen, stems probably from his insistence upon the fact that man is no longer master of even his own body, let alone center of the universe. More insulting is that this has come about by man's own workings and that there is no escape. this trap is of course 'language.' Aside from this groomy picture, Lacan fortunately promises great many hopes for feminism, by going 'back to Freud' many feminist scholars find incalculably valuable insights in his writings. If once arch male-chauvinist Freud can help enhance woman's claims and rights, it is in no small prat thanks to the great reformist Jacques Lacan.

액정 8OCB(octyloxycyanobiphenyl)에 액정 5OCB(pentyloxycyanobiphenyl)를 무게비로 혼합하여 혼합액정 (8OCB+5OCB)을 만들었다. 이 혼합액정은 5OCB의 무게비에 따라 McMillan지수 (??)가 감소하였다. 그리고 Rayleigh 광산란 실험방법을 이용하여, 순수 8OCB와 혼합액정의 네마틱-스멕틱 A 상전이 근처의 네마틱상에서 산란된 빛의 세기를 온도와 함수로 측정하였다. 실험데이타 분석결과는 휨(bend) 탄성 상수에 비례하는 세로방향 상관거리(??)는 McMillan 지수에 관계없이 임계지수 ??=0.66±0.03을 갖고 발산하였다. 이 값은 de Gennes의 모델에서 제시된 ??=0.67과 일치함을 알수있다. By utilizing Rayleigh scattering technique, we have measured the temperature dependence of scattered light intensity near nematic to smectic-A phase transition point in the pure 8OCB(octyloxycyanobiphenyl) and its mixtures contaning 5, 10, 15 weight percentage of 5OCB(pentyloxycyanobiphenyl). From analysis of these data. it is found that the longitudinal correlation length (??) diverges with critical exponent ??=0.66±0.03 independent on McMillan parameter (??). This result is consistent with de Gennes model (??).

This study have two different purpose; one is to compare the cardiorespiratory function of male and female four student groups: elementary-, middle-, high-, and college level, the other is to produce the prediction equations for evaluating the maximal oxygen uptake and AT of the same groups. The all subjects in this study were 157: elementary school, middle school, high school, and college, is 49, 41, 28, 39 respectively. 1. Maximal Oxygen Consumtion 1) Body size components The body weight, FFW, VO₂max of both sex showed very high positive correlation:0.88∼0.94. However, male subjects’ slope was 8∼15% higher than that of females. On the other hand, Both male and female subjects’body weight, FFW and VO₂max/㎏ showed very low negative correlation:-.05∼ -.14. 2) Breathing components At the VO₂level, ?? was significantly low in accordance with the school levels; V?? of college level was most low among the four school levels. Minute ventilation(??) between male and female was neally same at the beginning stage of exercise. When their VO₂ reached at 1.5ℓ/min point, however, there was significant difference between male and female subjects’ ??. Like minute ventilation, male subjects’breathing rate(BR) was significantly lowered in accordance with the rise in school levels(p<.01). Female subjects BR, however, did not show significant difference among the four school levels although it was fewly decreased by the rise in school levels. 3) Circulation components The heart rate at every sumaximal intensity was significantly different between male and female, and among four levels of school as well. In other words, male subjects’submaximal heart rate was higher than that of female subjects by the rise in school level. Maximal heart rate, however, did not show significant sifference at all cases. Subjects’O₂pulse, compared at the point of VO₂1.0ℓ/min, did not show any significant difference between male and female, and among four grades as well. When it compared at the range of VO₂1.5∼2.5ℓ/min, however, there were significant differences between male and female, and among four levels of school as well. 4) The respiratory exchange ratio components The respiratory exchange ratio(R) at every sumaximal intensity was not significantly different between male and female, and among four levels of school as well. The respiratory exchange ratio(R) was increased gradually in accordance with the exercise intensity. 2. Anaerobic threshold The difference of AT-VO₂between male and female was gradually grown large by the level-up of their school levels; elementary school students had lowest AT-VO₂among four levels of school. There was not significant difference in AT-VO₂/㎏among four levels of school although AT-VO₂/㎏ was also higher in male than female. Like AT-VO₂,the difference of AT-HR between male and female was rapidly grown large by the level-up of their school levels. 3. The prediction equations of VO₂max, AT-VO₂and AT-HR Both male and female subjects’R and coefficients of variation of the prediction equations on VO₂max was 0.92∼0.95 and 10.8∼12.5% respectively. Both male and female subjects’R and coefficients of variation of the prediction equations on VO₂/㎏ was 0.40∼0.50 and 11.3∼16.0% respectively. Both male and female subjects’R and coefficients of variation of the prediction equations on AT-VO₂was 0.74∼0.88 and 6.6∼11.7% respectively. Both male and female subjects’R and coefficients of variation of the prediction equations on AT-HR was 0.52∼0.58 and 4.9∼6.7% respectively. Four prediction equations for each sex presented as follows. _______________________________________________________________________ VO₂max M Y=0.589+0.064AGE +0.021WT+0.003HT+0.358BSA ml/min F Y=-1.879+0.024AGE+0.039WT+0.025HT-1.587BSA _______________________________________________________________________ VO₂max /kg M Y=39.4+1.29AGE-0.50WT+0.04HT+5.57BSA ml/㎏/min F Y=-21.1+0.396AGE+0.343WT+0.857HT-65.63BSA _______________________________________________________________________ AT-VO₂ M Y=1.462+0.021AGE+0.029WT-0.011HT+0.157BSA l/min F Y=-0.199+0.019AGE-0.004WT-0.010HT+2.063BSA ________________________________________________________________________ AT-HR M Y=300.6-1.76AGE+0.31WT-0.79HT+5.73BSA beats/min F Y=270.6-2.063AGE-3.005WT-1.859HT+255.1BSA ________________________________________________________________________

FC-25계 회주철의 이온질화처리에 따른 표면특성과 고온산화거동에 관한 연구

Surface properties and high temperature oxidation behavior were investigated for FC-25 Gray Cast Iron(GCI) and the ion nitrided GCI(N-GCI). The GCI was pre-cleaned to improve hardness to the optimum pre-sputtering parameters with an Ar/H₂ ratio of 1/2, working pressure of 3 torr, working temperature of 550℃ and working time of 1hour. The optimum nitriding conditions for the maximum hardness of 560575 Hv were an N₂/H₂ ratio of 3/1, working pressure of 3 torr, and working temperature of 575℃. The thickness of graphite in the GCI was increased by increasing the working temperature from 525℃ to 595℃ for the nitriding time of 6-18hrs. XRD patterns showed FeO and Fe₂O₃ peaks for both the oxidized N-GCI and GCI at temperatures of 600℃ and 800℃ under atmospheric environment for both 24 and 60hours. At 800℃, above the Fe4N decomposition temperature of 680℃, the oxidation rate of N-GCI was greater than that of the GCI. The most abundant nitride, Fe4N, was decomposed and the nitrogen gas given off by the decomposition made the protective film porous by degassing through the film. But at 600℃, below the decomposition temperature, the degree of oxidation of N-GCI was lower than that of the GCI because the nitride film worked as protective barrier for oxidation.

Rayleigh 광산란 실험방법을 이용하여 액정 Octyloxycynobiphenyl(8OCB)의 네마틱-스메틱 A 상전이 근처의 네마틱상에서 산란된 빛의 세기를 온도의 함수로 측정하였다. 실험 데이타 분석으로부터 bend 탄성상수(K₃)에 비례하는 세로 방향 상관거리 ??가 임계지수 ??=0.64±0.02를 갖고 발산함을 알 수 있었다. 이 결과는 de Gennes의 모델에서 계산된 값인 ??=0.67과 유사함을 알 수 있었다. By utilizing the Rayleigh light scattering technique, we have measured the temperature dependence of scattered light in the nematic-smectic-A phase transition point of Octyloxycynobiphenyl(8OCB). The temperature dependence of bend elastic constant K₃is deduced from analysis of this data, and it is found that the longitudinal correlation length ?? diverges with critical exponent ??=0.64±0.02. This result is similar to de Gennes's prediction ??=0.67.

FC-25계 회주철의 Boro-Nitriding 복합 표면처리에 따른 표면특성과 고온산화거동에 관한 연구

허인창,손근수,윤재홍,조동율,박봉규,김현수,김인수 대한금속재료학회 2005 대한금속·재료학회지 Vol.43 No.2

Surface properties and oxidation behavior were studied for FC-25 gray cast iron (GCI), ion nitrided CCI (N CCI), powder boronized CCI (B GCI) and powder boronized N CCI (B-N GCI). A boride (Fe2B and FeB) layer with a tooth shape was formed by boronizing GCI at 650℃. The thickness and hardness of the layer were proportional to boronizing temperature and time. The hardness was decreased as the depth of the boronized layer increased. The activation energy for boride formation was about 74 kJ/mol. The thickness of the graphite layer formed by boronizing was increased by increasing temperature and time. A silicon layer insoluble to borides accumulated beneath the boride layer. The major phases were Fe4N, Fe3N and FeN in the nitride layer formed by ion nitriding. The thickness and hardness of the layer increased with increasing nitriding temperature and time under the Fe4N decomposition temperature of 680℃. The hardness was maximum at the surface and decreased with increasing nitrided depth on B-N GCI at 700℃, above the Fe4N decomposition temperature. Hardness of B-N GCI at the layer depth of 10 μm was 1000 Hv, which was lower than that of the B GCI at the same condition. Also the layer thickness was 50 gm; 10 μm deeper than that of B GCI. The reason was that the nitrogen gas given off by the decomposition made the layer porous and facilitated the diffusion of oxygen and other reactants. The samples were oxidated at 800℃ for 48hrs under atmospheric air. Oxidation rate was in decreasing order of N GCI, GCI, B GCI and B-N GCI. Oxidation rates were greatly influenced by the diffusion of nitrogen gas formed by Fe4N decomposition over the decomposition temperature of 680℃ and the oxidation barrier of the less corrosive boride layer.

단결정 Si(111) 위에 형성된 Ti-실리사이드에 대한 RBS 및 XRD 분석

이중환,권오준,최치규,박동수,김건호,이상환,이의완,곽호원 濟州大學校 基礎科學硏究所 1991 基礎科學硏究 Vol.4 No.1

초고진공 상태에서 p형 Si(111)기판에 Ti을 증착한 후 고진공에서 열처리하여 Ti-실리사이드를 형성시켰으며, Ti-실리사이드의 상전이 및 형성운동학은 2 MeV⁴He? 이온 후방산란과 x-선 회절방법으로 규명하였다. 형성된 TiSi₂는 결정학적으로 C49(ZrSi₂)와 C54 구조의 두 종류로 확인되었다. C49 TiSi₂상은 열처리온도가 700℃이하의 저온에서 형성되었고, 700℃ 이상의 고온에서는 C54 TiSi₂상으로 나타났다. 본 연구에서 확인된 C54 TiSi₂전이온도(??)는 700℃ 였고, TiSi₂형성온도 영역내에서 TiSi₂ 층두께(χ)와 열처리시간(t)의 관계는 저온(700℃ 이하)일 경우 ??이고, 고온(750℃ 이상)에서는 χ=ct+d 의 관계식이 만족됨을 알 수 있었다. 이것은 700℃ 이하에서 TiSi₂ 형성기구가 Si 확산에 의해 제어되며, 750℃ 이상에서는 핵형성 제어에 의하여 계면반응하는 것으로 나타났다. Titanium silicides were prepared by depositing titanium film on p-type Si(111) followed by annealing in ultra high vacuum. The growth kinetics of Ti-silicide has been studied by using ion backscattering spectrometry and x-ray diffractometry. Two crystallographic structures of Ti-silicide were identified the (ZrSi₂)structure and C54. The C49 TiSi₂ phase was formed at low annealing temperature(<700℃),and it transformed to the C54 phase over 700℃. The relation between the thickness of TiSi₂ layer(χ) and the annealing time(t) was ?? when annealing temperature was under 700℃ and χ=ct+d when that was over 750℃. The former implied that the formation of TiSi₂ was controlled by diffusion and the latter by nucleation of at the Ti/Si(111) interface.

김병성,정영철,변영태,박경현,김선호,임동건 광운대학교 신기술연구소 1996 신기술연구소논문집 Vol.25 No.-

MOCVD(metal-organic chemical vapour deposition) 방법으로 성장시킨 이중 이종접합구조GaAs / AlGaAs 웨이퍼를 이용하여 광위상변조기를 제작하였다. 제작과정에서 도파로와 절연층의 형성시 동일 포토레지스트 패턴을 이용하는 자기정렬공정을 개발하여 그 효용성을 입증하였다. Fabry-Perot 간섭법을 이용하여 변조기의 위상변조효율을 측정하였으며, 1.31㎛ 파장에서 TE 편광의 경우 22.5˚/Vmm의 위상변조특성을 얻었다. An optical phase modulator is fabricated in GaAs / AlGaAs double heterostructure wafer grown by MOCVD. A self-aligned process, in which the same photoresist pattern is used for both the waveguide etching and the insulation layer formation, is developed and is found to be very useful. Fabry-Perot interference technique is applied to the measurement and the phase modulation efficiency is measured to be 22.5˚/Vmm at 1.31㎛ for TE polarization.
