The study of Jungpung(中風)'s section in Chungumyobang (千金要方, 諸風門) by Sonsamak(孫思邈) showed the following results. 1. The cause of Jungpung(中風) in Jungpung(中風)'s section in Chungumyobang (千金要方, 諸風門) was quotated from the theory of Naekyung(內經) -Pung(風) evil from the external environment invade on Hu(虛) of human body(外來風邪, 內虛邪中). 2. At Jungpung(中風)'s section in Chungumyobang (千金要方, 諸風門), he devided into the four classes of Jungpung(中風)'s symptom-Pyungo, Pungbi, Pungyi, Pungbi(偏枯, 風?, 風懿, 風痺)-, and this classification had a great influence on the next generations. 3. At Jungpung(中風)'s section in Chungumyobang (千金要方, 諸風門), he understanded that changes of Jungpung(中風)'s pathology depended on the Eum-Yang-Han-Yul-Hu-Shil(陰陽寒熱虛實) of the patients. 4. At Jungpung(中風)'s section in Chungumyobang (千金要方, 諸風門), he gathered and rearranged various prescription which accumulated the clinical experiences during the period from Naekyung(內經), Sanghan(傷寒) times, to Tang(唐)'s dynasty. There were major Jungpung(中風)'s prescription -Sosokmyungtang(小續命湯), Daesokmyungtang(大續命湯), Jukryuktang(竹瀝湯), Jihwangjun(地黃煎), Dokhwalgisaengtang(獨活寄生湯) etc. And the principle of treatment was the remedy method of removing evil through sweating(發汗祛邪法). 5. Chungumyobang(千金要方) showed the development of quality, quantity in their prescription comparing the fomer ages. And the method of classification of Jungpung(中風)'s symptom had a great influence on the next generation in clinical aspect. But the basic theory in Chungumyobang(千金要方) coudn't get out of the limits of Naekyung(內經), Gumgueyoryak(金?要略).

최은정(Choi, Eun-Jeong) 한국외국어교육학회 2012 Foreign languages education Vol.19 No.1

This study ha that after examining Discourse Hypothesis which revealed relation between narrative structure and tense-aspect it examines overall whether to apply hypothesis and using patterns of tense-aspect morphology as its object. On this study, to investigate using conditions of tense-aspect appeared in narrative discourse of Japanese learners of Korean, I collected data through story-rewriting task and intended to figure out difference by setting up native speakers as a comparative group. So, I intended to analyze whether differences in learners' use of tense-aspect exist according to narrative structure and examined changing patterns according to improvement of proficiency levels in using tense morpheme. Also, I intended to interpret learners' using patterns of tense-aspect by investigating whether distribution of lexical aspect varies according to narrative structure. According to the results, learners present differences in using tense aspect to distinguish foreground and background. Especially, in foreground using rate of past tense was high and in background various using patterns of tense were identified. In an aspect of using rate of tense-aspect, differences between high-ranking learners and low-ranking learners could not be identified and using patterns of high-ranking learners and native speakers were similar only in foreground. All lexical aspects showed significant differences in distribution according to narrative structure and I can identify the correlation between distribution of tense-aspect and, division criteria of narrative structure and three semantic features of lexical aspect in an aspect of temporality.

Congenital cytomegalovirus (CMV) infection is the most common nongenetic cause of sensorineural hearing loss and a major cause of visual, intellectual, and neurodevelopmental impairment worldwide. The seroprevalence of CMV among women of childbearing age in developing countries reaches almost 100%, and the incidence of CMV infection in neonates is 1%-2%. Approximately 87% of the infected neonates are asymptomatic at birth and 13% of them have permanent sequelae. The burden of congenital malformations due to congenital CMV infection is higher than that due to Down syndrome, fetal alcohol syndrome, and spina bifida. Nevertheless, there is little knowledge regarding congenital CMV pathogenesis, diagnosis, treatment, and prevention. In this study, we report a case that showed sequential changes of fetal brain following CMV infection in pregnancy. Additionally, we reviewed the latest information on the diagnosis, treatment, and prevention of congenital CMV infection.

최은정(Eun Jeong Choi),김세훈(Se Hun Kim),심상희(Sang Hee Shim),정현정(Hyun Jung Chung),방우석(Woo-Suk Bang) 한국식품과학회 2012 한국식품과학회지 Vol.44 No.4

약용식물 6종을 메탄올로 추출한 다음, n-hexane층을 DMSO에 녹여 항산화 활성을 측정·비교하여 기능성 소재인 천연 항산화제로써의 활용 가능성을 조사하였다. DPPH를 이용한 라디칼 소거능 실험에서는 250 μg/mL 농도에서 보골지가 대조군인 ascorbic acid에 비해 높은 유리기 소거능에 의한 항산화 활성을 나타냈다. 농도 500 μg/mL 에서는 ascorbic acid가 가장 높은 항산화 활성을 보였다. ABTS 유리기 소거능 실험에서는 농도 증가에 따른 항산화 활성이 DPPH assay와 상반된 결과를 나타냈고, 특히 보골지의 항산화 활성이 대조군인 ascorbic acid보다 유의적으로 높게 나타났다. DPPH 라디칼, ABTS 유리기 소거능 실험 결과 공통적으로 우수한 것으로 조사 된 약용 식물은 반지련, 보골지이며 500 μg/mL 이상의 농도에서 ascorbic acid와 유사한 90% 활성을 보였으며 750 μg/mL 농도에서는 ascorbic acid 보다 우수한 유리기 소거 활성을 보였다. 따라서, 반지련과 보골지는 항산화 활성이 우수하므로 천연 식물소재로 이용하기에 적합하며, 천연물의 추출 부위, 용매, 추출 조건에 따라 다양한 항산화 활성 능력을 기대 할 수 있으므로 천연 항산화제로서의 응용 가능성 또한 있을 것으로 사료된다. The objective of this study was carried out in order to evaluate the antioxidative activities of n-hexane fractions from medicinal herbs. Certain parts from 6 species of edible and medicinal herbs were extracted with methanol. Radical scavenging activity of the n-hexane fractions against DPPH and ABTS radicals were observed to be high in Psoralea corylifolia, and Scutellsria barbata it also significantly increased (p<0.05). For a comparison of the effect of various concentration of fractions, as the concentration of treatment increased, the antioxidative effects on radical scavenging activity also oncreased; yet it was not significant. The antioxidative effect of medicinal plants was dependent on the concentration but was not significant. Therefore, these results indicate that edible wild plants, such as Psoralea corylifolia, and Scutellsria barbata may be useful as potential antioxidant sources for improving the human antioxidant defense system against disease.

약용식물 3종에 대한 항균활성 결과, 보골지와 오미자 분획층에서 계혈등 분획층보다 높게 나타났다. 계혈등과 보골지 n-hexane 분획층에서 그람 음성균보다 그람 양성균에 대한 항균활성이 유의적으로 높게 나타났으며(p<0.05), 항균활성은 농도가 증가함에 따라 증가하였다. 계혈등 n-hexane 분획층의 L. monocytogenes에 대한 MIC는 7.765 (mg/mL), 보골지 n-hexane 분획층의 B.cereus, L. monocytogenes, E. coli 균에 대한 MIC는 2.03 (mg/mL), 오미자 분획층의 (L. monocytogenes), E. coli 균에 대한 MIC는 8.5 (mg/mL)로 나타났으며, 오미자 n-hexane 분획층의 MIC가 모든 균주에서 가장 낮게 나타났다. 약용식물 추출물의 항균활성에 대한 열 안정성 실험결과, L. monocytogens에 대한 계혈등 n-hexane 분획층을 제외하고는 100℃에서 10분간의 열처리에도 항균 활성의 변화가 없었다. 본 연구 결과 보골지와 오미자 n-hexane 분획층에서 비교적 높은 항균활성을 나타냈다. 이러한, 약용 식물은 다양한 생리활성 및 기능성 성분을 포함하고 있어 천연 항균제의 유용한 자원으로 이용 될 수 있으며, 식품산업 발달에 기여 할 수 있을 것으로 사료된다. This study was performed to identify safe natural food preservatives from medicinal herbs and to evaluate the antimicrobial effects of medicinal plants against microorganisms. Medicinal herbs were extracted 3 times with methanol at 45℃ for 3 h and fractionated with n-hexane. The antimicrobial effects of the fractions were determined by measuring the diameter of the inhibition zone by using an agar-well diffusion assay. The MIC of fractions for the inhibition of microorganisms was determined using a microplate reader. The antimicrobial effects of fractions were greater against gram positive bacteria than against gram negative bacteria, but the difference was not significant. The antimicrobial effects of fractions were concentration dependent. While these results have implications, the underlying mechanisms of microbial inactivation need to be further elucidated. The results showed the possibility of developing safer food preservatives.

<문화,문학> : 철응(鐵凝)의 『매괴문(매괴門)』다시 읽기 _인물의 “되기”를 중심으로-

최은정 ( Eun Jeong Choi ) 경희대학교 비교문화연구소 2013 비교문화연구 Vol.31 No.-

This thesis analyzes various becomings of female characters in rose Grate written by Tie Ning. By this analyzation, we can pick out what identity the female characters eager to have decomposed, what identity they hope to create, and what do these procedures mean. Si Qiwen`s ``becoming male`` presents strong desire to shift from periphery to center. However, it is meaningless when her tragic life can not be justified by those same female people. Zuxi`s ``becoming wanderer`` shows that Tie Ning refuses usual reality of woman`s life which vest in man. Sumei`s ``becoming mother`` is the exact point where torn female ego gets to consolidate, and it means Tie Ning takes ``mother-becoming`` as ultimate truth of woman`s life. Besides, Tie Ning finds women`s becoming something new as escaping from the other and she denies equation of man with savior.

1990년대 중국소설에 나타난 남성성 연구(2) — <雨天的棉花糖>과 <那个夏季那个秋天>을 중심으로

崔銀晶(Choi, Eun-Jeong) 한국중국소설학회 2020 中國小說論叢 Vol.62 No.-

본고는 <雨天的棉花糖>과 <那个夏季那个秋天>를 대상으로 하여, 남성성이 남성자아의 정체성 구축에 어떻게 작용하고 있는지를 살펴보았다. 홍더우와 겅동량은 가부장제에서 규정한 남성성에서 일탈한 개별화된 남성성을 전시한다. 이들의 비극은 두 가지 측면에서 사유할 가치가 있다. 첫째, 지배적 남성성의 해체이다. 이는 두 가지 측면에서 나타난다. 하나는 지배적 남성성이 남성자아를 억압함으로써 실천된다는 것이다. 다른 하나는 지배적 남성성의 구축 여부와는 별개로 나타나는 남성자아의 분열이다. 이는 지배적 남성성의 실현 불가능성, 허상성을 보여준다. 둘째, 이분화된 성별 시스템의 공고함이다. 홍더우의 죽음은 이분화된 성별 구조 안에서 개별화된 남성성을 수용하지 않는 사회문화적 심리를 보여준다. 반면, 겅동량의 자아분열은 개인에게 내면화된 이분화된 성별 인식을 증명한다. 요컨대, 이들의 비극은 이분화된 성별 구조 안에서, 다양한 남성성/들이 문화적으로 재현되는 것과 이러한 다양한 남성성/들이 동일한 가치를 부여받고 수용되는가에 대한 문제는 별개임을 설명한다. 개별화된 남성성을 부여받은 소년들의 ‘남성 되기’ 서사가 보여주는 의미가 여기에 있을 것이다. This study explores how masculinity contributes to establish its identity as male subjectivity by observations on <雨天的棉花糖> and <那个夏季那个秋天>. Their tragedies are worthy to be evaluated in two aspects. The first one is the deconstruction of hegemonic masculinity. It appears in two ways. The hegemonic masculinity is practiced by suppressing male subjectivity, and male subjectivity is deconstructed regardless of success or failure in winning hegemonic masculinity. It proves that hegemonic masculinity is unachievable and illusive. The second aspect is the firmness of the bisected gender system. The social and cultural mentality does not accommodate individualized masculinity in the bisected gender system, and it is rigid enough to lead Hong Dewu to his death. On the other hand, Geng Dongliang feels lost because he recognizes his internalized recognition of bisected genders. The tragedies explain that whether various masculinities are practiced in culture or not is one question, and whether the masculinities deserve equal value and get accepted or not is another question in the bisected gender system. As Hong Dewu and Geng Dongliang’s tragedies, the space for various masculinities will get narrower when the subjectivities, which does not be explained as dominant and universal, get suppressed in the processes of becoming males. The writer must have had enough his reasons and meanings for focusing on these particularly non masculine boys, and making narratives on their journeys of becoming a man.
