웹툰에 드러난 남성 동성사회성(homosociality) 양상 : 박태준 작가의 작품을 중심으로

남미자(Nam, Mi-Ja),박성태(Park, Seong-Tae),임세원(Lim, Sewon) 한국교육사회학회 2022 교육사회학연구 Vol.32 No.1

이 연구는 박태준의 네이버 연재 웹툰 싸움독학 (2019.11.15~현재)과 한남동 케이하우스 (2018.12.6~2019.10.31.)에 나타난 남성 동성사회성이 어떻게 드러나는가를 분석하는 것이 목적이다. 최근 남성 청소년의 백래시와 반페미니즘 정서가 확산되고 있는 가운데, 남성 청소년에게 영향력 있는 웹툰 분석은 향후 남성 청소년을 이해하는 데 의미있는 자료가 될 것이다. 두 작품의 분석을 통해 확인한 남성동성사회성 양상은 다음과 같다. 첫째, 남성의 성장은 ‘아직’ 남자가 아닌 자들이 ‘진짜’ 남성들에게 인정받고, 둘째, 인기 있는 여성을 소유하여 성적 주체가 되며, 셋째, 이 과정에서 호모포비아와 여성혐오를 동반하는 것으로 의미화 된다. 이것이 남성의 성장이라고 인식할 때 청소년들은 지속적으로 자신을, 그리고 여성을 혐오할 수밖에 없게 된다. 이러한 분석을 토대로 본 연구는 젠더 교육과 연구의 지형의 변화와 확장을 제안한다. 여성 청소년뿐 아니라 남성 청소년 역시 하나의 젠더 범주로 묶일 수 없는 다층적이고 교차적이기 때문에, 젠더 연구와 교육에서 여성과 남성의 이분법적 시각을 벗어날 필요가 있다. The purpose of this study is to analyze how the male homosociality is revealed in the webtoons written by Park, Tae-joon. Amid the recent spread of backlash and anti-feminist sentiment among male adolescents, webtoon analysis that is influential to male adolescents will be meaningful data for understanding male adolescents in the future. The male homosocial aspects confirmed through the analysis of the two works are as follows. First, the growth of men is recognized by not yet men, and secondly, they become sexual subjects by owning popular women, and thirdly, it is meant to be accompanied by homophobia and misogyny in the process. When recognizing that this ismale growth, adolescents have no choice but to constantly hate themselves and women. Based on this analysis, this study proposes changes and expansion of the topography of gender education and research. Since not only female adolescents but also male adolescents are multi-layered and cross-sectional that cannot be grouped into one gender category, it is necessary to deviate from the dichotomy perspective of women and men in gender research and education.

The study was conducted to evaluate the difference of life style, subjective symptoms and health cognition depending on the Sasang Constitution in the industrial workers. The results were as follows ; Constitutional distribution among exposed group were Tae-eum In(38.4%), So-eum In(35.2%), and So-yang In(26.4%) and it was turned out that Tae-eum In took a higher portion of Sasang constitution than other constitutions in technician workers. 'Exercise' and 'Obesity' were found most in Tae-eum In, In So-eum In there were many 'Normal' weight and 'Having digestive disorders' were found most in So-eum In. There were no significant difference in the health cognition among the constitutions. The closer to 'normal' weight, the higher prevalence in 'having' concern about health condition and the more 'normal' condition in sleeping, the higher prevalence of 'having' self-confident in present health.

키토산 올리고당 첨가 증편 발효 중 Dextran 형성과 증편의 내부구조에 관한 연구

남태희,우경자 동아시아식생활학회 2003 동아시아식생활학회지 Vol.13 No.2

This study was carried out in order to investigate the dextran formation and the internal structure of the chitosan-oligisaccharide(COS) Jeung-Pyun during the fermentation. To develop a functional Jeung-Pyun, COS was added to the rice at the level of 0, 2, 4, and 6% to the 2-hour-soaked rice. The pH, dextran and reducing sugar contents of COS batter, specific volume and the internal structure of COS were analyzed as a function of fermentation time. The specific volume of COS peaked at the 3 hour fermentation. The pH values of COS batters reduced with the fermentation time. The dextran content of the control batters peaked at the 7 hour fermentation. In contrast, the dextran contents of COS batters reduced up to 7th hour of fermentation, and then increased slowly until 20th hour of the fermentation process. From the air pore size and distribution of COS observed by SEM, the COS fermented for 3 hour was judged as the best. It was concluded that COS prevented the formation of dextran at the early stage of fermentation process.

金亨資,全泰玉,加藤康司 釜山工業大學校 1994 論文集 Vol.36 No.-

Sliding friction between spherical pin of 8mm in diameter and flat(disk) substrates coated with vacuum-deposited thin film was measured under on ultra high vacuum pressure for various materials, rate of film supply(8∼210nm/min), sliding velocity(1.5∼67.0nm/s), flash temperature. It was found that the most effective lubrication is obtained when the adhesion between pin of Si₃N₄ and disk of SUS440C is high and that between pin of Si₃N₄ and disk of Si₃N₄ is low. When In film is used as a lubricant between pin of Si₃N₄ and disk of stainless steel, the friction coefficient has a value as low as 0.04. In this case, the normal load W and the sliding velocity V are expressed as 1ON and 24mm/s for 10??Pa. The dependence of μon the thickness h of the Ag film, which is used as a lubricant between Si₃N₄pin and SUS440C(Q) disk is expressed as μ=0.12 for W=10N and V=24mm/s when the film is thicker than 100nm. A brief discussion on these relations is presented from the viewpoint of the real contact area.

金泰玩,具滋龍,李昌熙 弘益大學校 科學技術硏究所 1997 科學技術硏究論文集 Vol.8 No.-

Langmuir-Blodgett(LB) technique is one of the ways of manufacturing organic this films. It has an advantage in alignment and orientation of the molecules in the films. It is being used to develop molecular electronic devices, gas sensor and etc. Phthalocyanine(Pc) is especially sensitive to the electron affinitive toxic gases, such as NO₂, NO, O₂, SO₂, and etc. It has chemiresistor properties, such as a change in electrical conductivity when it is exposed to the gases. In this study, CuTBP LB films were manufactured. NO₂ gas detection ability of the above LB films were examined. A chemiresistor device using CuTBP LB films was made and the possibility as a gas sensor was investigated. To increase the current level at constant bias, interdigital electrode was used. A lateral distance d(2, 1, 0.5mm) between fingers and number of finger pairs N were varied. We have observed that a conductance G is proportional to 1/d and N. when we compare the conductance between N = 1 and N = 25, the current where N = 25 is higher than that of N = 1 by 60 times. The sensitivity is about 50 times greater and stable.

본 연구는 차나무의 신초를 이용하여 기내에서 여러가지 배양조건에 따른 캘러스의 catechin류 함량을 분석하여 생산성이 높은 배양조건을 찾고자 실시하였다. 신초배양시 캘러스는 0.5mg/L NAA와 1mg/L BA 조합 처리구에서 가장 잘 유도되었다. 이 조건에서 유도된 캘러스를 가지고 thiamin-HCI, PVP, taxifolin과 quercetin을 농도별로 처리하여 4주간 배양하여 생장 및 catechin류 함량을 조사하였다. 캘러스의 생장은 30mg/L thiamin-HCL, 200mg/L PVP, 1 mM taxifolin, 0.01 mM quercetin처리시 대조구에 비해 2~3배의 생장를 보였다. 차나무 잎의 주성분인 catechin류를 분석하고자 신초와 여러조건에서 배양된 캘러스를 가지고 분석한 결과를 보면, 캘러스에서 높은 함량을 보였다. 또한 신초에서의 catechin류는 EGC, EGCG, ECG등은 검출되었으나, EC는 검출되지 않았다. 그러나 배양된 캘러스에서는 4가지 성분이 모두 검출되었다. 각각의 성분들의 최적 배양조건을 보면, EGC는 500mg/L PVP, EC는 100mM quercetin, EGCG는 10 mg/L thiamin-HCI, ECG는 10mM taxifolin처리구에서 가장 높은 함량을 보였다. This study aimed to measure the growth of callus cultured under MS medium with thiamin-HCI as a vitamine. PVP as the antioxidant. taxifolin and quercetin as precursors of catechins and to select the clone producing catechins highly. Callus induction from Thea sinensis young leaf was great in the MS medium with 0.5mg/L NAA and 1 mg/L BA. When components of callus were compared with those of young leaf. Four kinds of catechins(EC, EGC, EGCG, ECG) were detected in cultured callus whereas EC not in young leaf. Catechins were detected most in the medium with 10mg/L thiamin-HCI. Expecially, EC was most as a 6.39mg/g. The content of catechins in PVP treatment was not different each other but was higher in 100 mg/L and 200 mg/L PVP than in control. When the callus was cultured in the medium with taxifolin and quercetin the caffeine content was lower than in the medium with not them. Also, the content of catechins in taxifolin and quercetin treatment was not different each other but it was highest in 10mM taxifolin and 100mM quercetin treatment.
