        서브마이크로미터 크기의 실리콘 음극용 폴리페난트렌퀴논-폴리아크릴산 전도성 고분자 복합 바인더

        상모,이병일,이재길,이정범,류지헌,형태,영규,오승모,Kim, Sang-Mo,Lee, Byeongil,Lee, Jae Gil,Lee, Jeong Beom,Ryu, Ji Heon,Kim, Hyung-Tae,Kim, Young Gyu,Oh, Seung M. 한국전기화학회 2016 한국전기화학회지 Vol.19 No.3

        나노 크기에 비해 부피 변화가 상대적으로 더 큰 서브마이크로미터 크기의 실리콘 음극의 성능 향상을 위해 도전재 역할을 하는 3,6-poly(phenanthrenequinonone) (PPQ) 전도성 고분자 바인더와 카복시기를 가져 결착력이 좋은 poly(acrylic acid) (PAA)를 블렌딩 한 복합 바인더를 도입하였다. PAA를 PPQ와 블렌딩하여 전극을 제조했을 때 결착력이 월등히 증가하였고 충방전실험 결과 PPQ 바인더를 단독으로 사용한 전극보다 안정된 수명 특성을 나타냈다. PPQ와 PAA의 함량 비율을 2:1, 1:1, 1:2(무게비)로 하여 각 전극의 수명 특성을 비교했을 때, PPQ의 함량이 가장 큰 전극(2:1, QA21)이 50번째 사이클에서 가장 좋은 용량 유지율을 보였다. 이는 PPQ가 입자 간 또는 입자와 집전체 사이에서 도전재로서 존재하여 전자가 이동할 수 있는 통로를 제공해 주고 PAA가 적절한 결착력을 제공해주어 전극의 내부 저항이 가장 작았기 때문이다. PPQ-PAA 복합 바인더를 사용한 전극은 입자 형태의 도전재인 super-P를 전체 전극 무게 대비 20%를 첨가하여 제조한 전극보다도 더 안정적인 수명 특성을 나타내었다. In order to improve performances of submicrometer-sized Si negative electrode which shows larger volumetric change than nano-sized Si, composite binders are introduced by blending between poly(phenanthrenequinone) (PPQ) conductive polymer binder and poly(acrylic acid) (PAA) having good adhesion strength due to its carboxyl functional group. Blending between PPQ and PAA shows an effect that the adhesion strength of the Si electrode with the composite conductive binder is greatly improved after blending and this makes its better stable cycle performance. Blending ratios between PPQ and PAA in this work are 2:1, 1:1, 1:2 (by weight) and the best capacity retention at 50th cycle is observed in the electrode with the blending ratio 2:1 (named QA21). This is because that PPQ plays a role of conductive carbon among the Si particles or between Si particles and Cu current collector and PAA binds effectively the particles and the current collector. According to this synergetic effect, the internal resistance of the Si electrode with the blending ratio 2:1 is the smallest value. In addition, the Si electrode with PPQ-PAA composite binder shows the better stable cycle performance than the electrode with conventional super-P conductive carbon (20 wt.%).

        윌리엄 블레이크의 예술가상

        김재오 ( Jae Oh Kim ) 한국18세기영문학회 2014 18세기영문학 Vol.11 No.1

        In the later years of his career, William Blake felt alienated from the public sphere of art society dominated by art dealers, patronage, connoisseur, publishers, and so on. The experiences of discord with commercialistic practices of art allowed him to recognize the contrast between the real life in imaginative arts and his ordinary existence. Blake’s ideological and emotional struggles to realize the ideal of art under the disadvantaged environment are reflected in Los, a Blakean figure of artist in Jerusalem. To be precise, Los tries to prevail on his own spectre to labour at the artistic creation. This agonizing spiritual struggle mirrors Blake’s predicament as an artist in the modern world. To transform Albion’s “spectral” system into Jerusalem, which is the intellectual community of art and sciences, Los builds up “Golgonooza” that helps to restore the integrity of senses and to unfold ‘minute particulars’ of life. However, the city of art is surrounded with the walls of oppression and exploitation that have conspired to obstruct liberty to exercise imagination and creativity. Thus, the artistic creation should be accompanied with the creation of relationship, in which an individual’s mental gift is fully appreciated and “intellectual war” encourages brotherhood and love among human beings.

        "영문학"의 제도화와 매슈 아놀드: 중심인가, 예외인가?

        김재오 ( Jae Oh Kim ) 영미문학연구회 2008 영미문학연구 Vol.14 No.-

        Matthew Arnold has been considered to be the founder of English Studies who played a key role in setting up ``literature`` and ``tradition`` as its sphere. Recent researches on the institutionalization of ``English``, however, point out that Arnold`s place in the education of English literature was marginal as opposed to our common sense. The main stream of English Studies of the day aimed at shaping the cultural identity of the British people. In this project, Wordsworth was appropriated into a cultural icon and established as a father figure in English Studies. For Arnold, this nationalistic and ideological propensity was at the stake of reinforcing the parochialism of English literature. The idea of a cosmopolitan confederation of criticism and the revaluation of Wordsworth in terms of his internationality were the product of his exceptional attempt to overcome the provincialism of the dominant cultual nationalism. Contrary to nationalistic Wordsworthians` ardent praises on ``philosophic poems``, Arnold illuminated Wordsworth`s international value with his genius of embodying simple joys of life in nature as displayed in short poems. Controversial it may be, Arnold`s ``criticism of life`` is understood to be the pursuit of the ``poetic truth`` for the ground of a true or international universality in the face of epistemological entanglement such as cultural nationalism dominated by narrow faith and abstract thinking.

        남근(Nam Keun Kim),이찬(Chan Lee),이숙환(Sook Hwan Lee),고정재(Jung Jae Ko),손태종(Tae Jong Sohn),오유경(Yu Kyoung Oh),안희정(Hee Jung Ahn),차광열(Kwang Yul Cha) 대한산부인과학회 2000 Obstetrics & Gynecology Science Vol.43 No.9

        목적 : 다중 중합효소연쇄반응 (Multiplex PCR) 방법을 이용하여 자궁경부암 환자에서 인유두종부 바이러스 (human papilloma virus; HPV)의 고 위험군과 저 위험군을 동시에 검색하고, 이를 진단 및 예후판정에 이용하고자 시도하였다. 연구방법 : 1995년 6월부터 11월까지 분당 차병원 산부인과에 내원하여 생검이나 수술적 적출술을 수행한 71명의 환자를 대상으로 실시하였다. Multiplex PCR 방법으로 한번의 RCR 수행으로 HPV 감염여부 및 고 위험군, 저 위험군을 동시에 typing하였다. 이때, HPV의 L1, E6, E7 DNA에 대한 3 set의 primer를 동시에 반응시켜 결과를 얻었다. 결과 : 총 68명의 자궁경부암 환자를 대상으로 HPV 감염여부 및 고 위험군과 저 위험군여부를 검색하였다. 이들을 자궁경부암의 진행정도에 따라 상피내종양 (cervical intraepithelial neoplasia; CIN)과 침윤암 (Invasive carcinoma; ICa)으로 구분하였다. 이들은 CIN I이 75% (9/12), CIN II가 75% (9/12), CIN III가 92.0% (23/25), 그리고 ICa가 94.7% (18/19)로 각각 나타났다. 또한, 고 위험군 (HPV16/18), 저 위험군 (HPV6/11) 및 기타 type이 각각 50.0%(34/68), 4.4%(3/68), 32.4%(22/68)로 나타났다. 전체적으로는 86.8%(59/68)의 HPV 감염 양성율을 나타냈다.결론 : 이러한 연구결과로 보아 다중 중합효소연쇄반응 (Multiplex PCR)은 자궁경부암 환자에서 HPV 고 위험군 및 저 위험군의 동시 분석에 매우 효과적인 방법으로 임상진단 및 예후판정에 널리 활용될 수 있을 것으로 기대된다. Objective : To investigate simultaneous detection of high and low-risk type of HPV in Korean cervical carcinoma using multiplex PCR method. Methods : HPV typing in cervical carcinoma was performed by multiplex PCR using three set of consensus primers for L1, E6, E7 of HPV DNA. Results : A total of 68 cervical carcinomas were examined. Histological examination revealed a specimen of carcinomas, which were classified as CIN I, CIN II, CIN III and invasive carcinoma (ICa). Of 68 cervical carcinomas, 75.0% (9 of 12) of CIN I, 75.0% (9 of 12) of CIN II, 92.0% (23 of 25) of CIN III and 94.7% (18 of 19) of invasive carcinoma (ICa) were positive for at least one type of HPV by the multiplex PCR. HPV 6/11, HPV 16/18 and other HPVs (general) were detected in 86.8% (59/68) were detected in 4.4% (3/68), 50.0% (34/68) and 32.4% (22/68) of cervical carcinomas of patients from Korea, respectively. Conclusion : We also confirmed that multiplex PCR is a simple, convenient, and cost-beneficial technique in simultaneous detection of high and low-risk type of HPV for genetic diagnosis in Korean cervical carcinoma patients.

        『연애하는 여인들』에 나타난 ``성``과 ``일``의 문제

        김재오 ( Jae Oh Kim ) 성균관대학교 인문과학연구소 2012 人文科學 Vol.0 No.50

        로런스는 『연애하는 여인들』에서 근대성의 문제를 문명사적 지평 속에서 사유한다. 그것은 창조력이 고갈된 근대서구문명에 대한 심층적인 진단인바, 남녀관계와 남남관계를 통해 ``성``과 ``일``이라는 주제가 새로운 문명의 창조와 얼마나 밀접한 관련이 있는지를 보여주는 작업이다. 본고에서는 버킨과 어술라의 관계가 이룩한 일정한 성취가 근대 서구문명의 병폐를 극복하는 과정과 동일한 괘도에 있으며, 이러한 성취가 버킨과 제럴드의 관계진전으로 발전하지 못한 상황 자체가 근대문명을 바라보는 로런스의 암울한 전망임을 밝히고자 한다. 또한 버킨과 어술라의 관계가 새로운 문명의 창조에 이바지하기 위해서는 서구문명에서 일정한 이탈을 수반해야 할 것이고 그 이탈은 서구문명 바깥의 존재에 대한 새로운 인식으로 이어져야 할 것임을 강조하고자 한다. D. H. Lawrence thinks over the question of modernity on the horizon of the history of civilization in Women in Love. The main point of this question is how a creative power has been exhausted in the anti-life flow of capitalism and what effects this destructive result has on human relationship and labor. Lawrence`s thinking reveals that the theme of ``sex`` and ``work`` is inseparably related with the creation of a new civilization. This paper aims to show that the achievement of Birkin-Ursula relationship takes the same trajectory as the process of overcoming maladies of modernity and that the failure of Birkin-Gerald relationship reflects Lawrence`s bleak outlook of western civilization. Brikin and Ursula become estranged each other owing to disagreement presumably traced back to the sexual difference and at this critical moment, their encounters with other people have great effects on the advancement of their relationship, To recognize the radical difference between their lover and other persons is essential in discovering ``otherness`` of beings. Thus, their sexual relationship constitutes a mysterious experience amounting to the state where their world becomes deeper inward, keeping open outward. Of course, it is uncertain what relationship this "new One" will create with "some few other people". Such people are difficult to find at least in this novel itself. Gudren and Loerke`s world is surrounded with ``will to conquest`` and ``frivolity``. The fact that Gerald with more sincerity meets his death reveals the possibility and limitation of his friendship with Birkin. That`s why Birkin`s search for a new civilization should include the breakaway from the old world and the heuristic recognition of beings hidden in the underside of western civilization.

        기억과 역사: 키츠의 『하이페리언』읽기

        김재오 ( Jae Oh Kim ) 영미문학연구회 2004 영미문학연구 Vol.7 No.-

        Keats`s Hyperion has been critically assessed as a less accomplished work than its revised version The Fall of Hyperion mainly because it is too Miltonic to be an original work. Sure enough, Keats`s personal urgency is fully impersonalized in the latter by working through an un-Miltonic Dantesque poetic mode as shown in the encounter between Moneta and the poet-narrator. In The Fall of Hyperion, however, the thematic focus falls on the establishment of the poet`s identity, so that the historical context where the very issue of identity comes into question is blurred in the poet-narrator`s dream vision. On the other hand, the central event of Hyperion, the fall of Titans and the advent of Apollo, alludes to the political situation and cultural ethos after Napoleon`s dethronement. Under this preposition this paper examines the relationship between Keats`s poetry writing and the internalization of historical knowledge. Keats configures various historiographies by reference to which some of the Titans interpret the fall in their own ways. Despite different and even contrary notions of history, their conceptual ground of history is derived from the world-view of the Enlightenment represented by Hyperion`s deity at the stake of falling with Saturn`s. The advent of Apollo replacing Hyperion, thus, raises a question as to what character a new "foreseeing" deity ought to have. In an encounter between Mnemosyne and Apollo, Keats makes it salient that such a deity presupposes the vitalization of historical knowledge to serve as a foundation of poetic creation.
