        19세기 미국의 문학지식인과 대중문화: 휘트먼의 「민주주의의 전망」과 연관하여

        유희석 영미문학연구회 2007 영미문학연구 Vol.13 No.-

        With the advent of globalization it is commonplace to hear that a geoculture that everyone shares finally comes to be realized. But it is equally easily argued that the geoculture itself is contaminated by the gobbling capital; homogenizing commercial culture symbolized by the Macdonald erodes the very foundation of Rabelaisean culture. These contradictory voices compel us to think over the role of literary intellectuals in shaping the common culture as a genuine public sphere which is neither of the two mentioned above, geoculture and Rabelaisean culture; the one is too vulnerable to the onset of commercialization leading to the mass culture while the other is no less inclined to the pitfalls of the vicious circle of binary opposites, the highbrow vs. the lowbrow. This paper purports to read W. Whitman’s post-bellum essay “Democratic Vistas” keeping in mind the dialectical tension of the literary intellectuals in 19th century America and its reading culture. Whitman’s argument against the general deterioration of spiritual conditions in America signally termed as ‘the Gilded Age’ offers us opportunities to muse on the possibility of the common culture as a desirable public sphere. His total vindication for the vocation of (national) literature as well as the positive role of literary intellectuals in engaging with consuming culture is one of the guideposts to the horizon of ensemble-Individuality.

        『주홍글자』론: 극적구조의 관점으로

        유희석 영미문학연구회 2004 안과 밖 Vol.16 No.-

        This paper purports to read The Scarlet Letter in terms of dramatic structure. To grasp this novel with the sense of a spectator is a felicitous way of disciplining literary scholarship in that it helps, first of all, to deal with the notorious duplicity of The Scarlet Letter; we can envisage more concretely in what ways “an equivocal hope” expressed in the denouement of the novel is related with the historical dilemmas that the writer faces in mid 19th century America. Further than that, we can picture more clearly how the real hope and the false consciousness of Hester Prynne and Arthur Dimmesdale are dubiously compromised, and in what sense the reader’s commitment on women’s liberation is an essential part of the critical understanding of the text, to say nothing of placing the ambiguous narrator in the context of narrative and of containing the centrifugal allegories in it. Through this kind of unconventionally conventional reading, we come to the conclusion that the human liberation is an unimaginable universal horizon unless enforced by the reader’s ultimate questioning on the Truth which inevitably embraces the intense engagement with his/her local reality.

        적출 자궁운동에 대한 Neuropeptide Y의 영향

        유희석,이경은,안영수 대한산부인과학회 1991 Obstetrics & Gynecology Science Vol.34 No.4

        토끼 자궁절편운동에 미치는 neuropeptide Y(NPY)의 영향과 다른 신경전달 물질과의 상호 연관성 및 칼슘과 칼륨이용과의 관계를 검색하여 다음과 같은 결과를 얻었다. 1. 토끼 자궁절편은 Tyrode액내에서 비교적 규칙적인 자발운동을 나타내었으며 estrogen 및 progesterone처치군에서 norepinephrine, acetylcholine 및 histamine은 용량 의존적으로 자궁절편의 자발운동을 증가시켰으나 5-hydroxytryptamine은 estrogen처치군에서 자궁운동을 억제시키고 progesterone처치군에서는 별다른 영향을 미치지 않았다. 2. Estrogen처치군에서 NPY(10-6M)는 토끼 자궁절편의 자발운동을 항진시켰으나 progesterone처치군에서는 별다른 영향을 나타내지 않았다. 3. 자궁 절편운동에 대한 NPY의 수축 증가반응은 phentolamine, atropine, chlorpheniramine 또는 indomethacin에 의해 봉쇄되지 않았다. 4. Cromakalim은 NPY에 의한 자궁 수축반응을 완전히 억제하였다. 5. 칼슘배제 고칼륨 탈분극 영양액 내에서 NPY는 자궁절편 운동에 아무런 영향이 없었으나 정상 Tyrode 액내에서 diltiazem은 NPY에 의한 자궁 수축반응을 억제하였다. 이상의 결과로 보아 NPY는 estrogen영향하에서 토끼 자궁절편의 자발운동을 증가시키는데 이러한 효과는 콜린성 및 아드레날린성 신경전달물질과는 무관하고 NPY자체의 수용체를 경유하여 나타나는 것이라 생각되며 이러한 작용을 나타내는 데에는 칼륨의 평형 전압 변동에 따른 칼슘의 세포내 유입이 관계할 것으로 생각된다. Among the nonadrenergic, noncholinergic transmitters, neuropeptide Y(NPY), vasoactive intestinal polypeptide and substance P are found in the female genital organs and they are known to regulate the uterine motility. NPY is consisted of 36-amino acid residues which is originally isolated from porcine brain and co-exist with the classical autonomic neurotransmitters in some sympathetic neurons. In particular, it was found in nerves around the vascular and nonvascular smooth muscle in the uterus, which suggests that NPY may have an important role in uterus. So far, however, few supporting studies are reported. In the present study, it was aimed to examine the effect of NPY on the motility of the isolated rabbit uterine strip and to investigate its mechanism of action. Rabbits weighing about 2 kg were spayed and treated either with estrogen(17- -estradiol:500 g/kg/day,s.c.) or progesterone(4-pregnene-3,20-dione:12.5 mg/kg/day,s.c.) for 1 week. After sacrifice, uterus was isolated and the uterine strip(1 mm 10 mm) was suspended in a chamber containing 1 ml Tyrode solution. The motility was recorded on a Polygraph(Model 7,Grass) through force displacement transducer. The results obtained are as follows: 1. Norepinephrine, acetylcholine and histamine increased the spontaneous motility of uterine strip of estrogen- or progesterone-treated rabbit dose-dependently. But 5-HT inhibited the contraction of estrogen-treated uterus and had little effect on progesterone-treated uterus. 2. NPY increased the motility of estrogen-treated uterus, but had little effect on progesterone-treated uterus. 3. NPY-induced uterine contraction was not blocked by phentolamine, atropine, chlorpheniramine or indomethacin. 4. Cromakalim completely blocked the uterine contraction induced by NPY. 5. The effect of NPY was abolished by diltiazem, and further, NPY had no effect on the uterine tension in Ca++-free high potassium depolarizing solution. These results indicate that NPY has a stimulatory effect via specific receptor on the uterine motility of rabbit, which is estrogen dependent and might be associated with extracellular calcium mobilization.

      • 자궁경부암 병기판정 기초검사시 새로운 보조방법으로서 고주파 질식 초음파의 가치

        유희석,이은주,장기홍,권혁찬,양정인,김행수,오기석 아주대학교 의과학연구소 1996 아주의학 Vol.1 No.1

        To investigate the efficacy of endoluminal ultrasound system (EUS) as a surrogate for high frequency transvaginal ultrasonography and as an optional baseline study in determining parameirial and stromal invasion of early stage cervical cancer, 52 women suspected of cervical cancer underwent EUS. A 12 MHz endoscopic probe was employed to radially scan the cervix for possible lesions suspected to be invasive cancer during a period of 6 months from Feb. 1 to July 1, 1995. Patients also underwent magnetic resonance imaging (MRI) and/or computerized tomography (CT) as a routine mode of baseline study, and were clinically staged by 3 independent physicians specializing in Obstetrics and Gynecology at the Department of Obstetrics and Gynecology, School of Medicine, Ajou University, Suwon, Korea. Thirty one patients subsequently received surgery appropriate for the stage of the disease and the final pathology findings were compared with the results of clinical staging, EUS, MRI/CT by regression analysis. The results showed that there was statistically significant correlation between MRI/CT and pathology (r=0.660, p<0.02), between EUS and pathology (r=0.803, p<0.01), and between clinical staging and pathology (r=0.825, p<0.01). It is concluded that there was significant statistical correlation t>etween EUS, MRI/CT, clinical staging and pathology, but the question remained as to the statistical superiority of EUS over MRI/CT with regard to parametrial invasion and stromal invasion depth assessment. Finally, EUS is useful as an alternative optional diagnostic tool in the baseline study of cervical cancer.
