권혁미 남서울대학교 2010 남서울대학교 논문집 Vol.16 No.1-2

This paper traces Toni Morrison's thought about racism in her non-fiction stories, interviews and biographies. Morrison, the first Afro-American Nobel Prize winner, has written a lot of manuscripts. Therefore there have been a great number of criticisms about the themes of her works from various perspectives. But I believe one common theme of her works is racism. Afro-Americans in the past had experienced oppression which impacted their lives negatively and had remained traumatized. Even after their emancipation from slavery by law, they were not liberated in real life. Through her characters during the slavery period, or descendants of slaves in her works, Morrison reveals that slaves were taken advantage of as the Other to prove white people's superior identities and that the media have manipulated the public opinions against the Afro-Americans. Morrison also attempts to convey through her writings how ex-slaves have overcome their traumas and have rebuilt their forgotten history. Examining her non-fiction stories provides a good basis for analyzing Morrison's fictions. This ensures that her creative writings have been accomplished for the benefit of the whole mankind as well as the Afro-Americans. Key Words : Toni Morrison, racism, Afro-American, non-fiction

This study was conducted to search for the α-glucosidase inhibitor from the natural products. In the previous study, the water extract of Gyrophora esculenta exhibited a potent inhibitory effect on α-glucosidase activities. Then, by bioassay-guided fractionation followed by chromatographic seperation of the water extract of Gyrophora esculenta, α-glucosidase inhibitor was isolated as GE974. GE974 showed significant inhibitory activities on some kinds of α-glucosidases in vitro. Its inhibitory mechanism seemed to be competitive for disaccharides. Also, it markedly inhibited α-glucosidases of intestine separated from both nondiabetics and diabetics.

최혁재,김남재,김동현 경희대학교 동서의학연구소 2001 東西醫學硏究所 論文集 Vol.2000 No.-

GE974, isolated from Gyrophora esculenta, showed significant inhibitory effect on several α-glucosidases in vitro in previous study. In the present study, GE974 showed significant inhibitory effect on blood glucose elevation in mice loaded with maltose, sucrose, starch and lactose. Also, it exhibited similar effect in alloxan and streptozotocin induced diabetic mice, and genetic diabetic mice(db/db mice) loaded with maltose in dose dependent manner. These results suggest that GE974 may possess hypoglycemic effect that inhibit competitively α-glucosidase activities.

In this study, We carried out the preparing standardization and regulation of processed Glycyrrhizae Radix(PGR) which have been widely used in oriental medicines. Glycyrrhizae Radix(GR) have been generally prepared by the stir-frying, or mix-frying with honey for purpose of decreasing sweetness and augmenting vitality. Firstly, we tried to standardize PGR prepared by the stir-frying. We purchased 14 kinds of PGR and non-processed GR(NPGR) at oriental physician's offices and oriental pharmacies on a nation scale, respectively. The amounts of dry on loss, water extract, diluted ethanol extract, ether extract, total ash, acid insoluble ash, glycyrrhizin(GL), glycyrrhetic acid(GA) and liquiritin(LQ) of them were examined. The amounts of dray on loss, GL and LQ in commercial PGRs showed remarkable decrease, while GA showed increase as compared with NPGR. In order to standardize preparing method of PGR, the effect of heating time on physico-chemical parameters and biological activities were examined. Physico-chemical parameters such as dry on loss, extract amount, GL and LQ contents in PGRs showed decrease, however, GA was increased with heating time as compared with NPGR. Also, GA obtained form heat-treated GR, was found as an artifact in PGRs. PGR was more effective than NPGR in vitro test of DPPH scavenging effect and TBA-Rs reducing effect. PGR and NPGR showed potent hepatoprotective effect on CCl_(1)-intoxicated rats. Especially, PGR prepared by 80 min of heating was the most effective. Considering these results, the optimal condition for PGR preparation was 150℃ for 80min.

The Process Safety Management (PSM) by the Law of Industry, Safety and Health has been performed for preventing major accidents of chemical plants since 1996. In terms of preventing chemical accidents more precisely, it is essential to develop a tool for quantitative risk assessment. For this, KOSHA (Korea Occupational Safety and Health Agency) developed an Integrated Risk Management System (IRMS) . The system is designed to assimilate data on chemical plant hazards from external database, to integrate these data with location information (topographic and demographic), and to make them user-friendly accessible. The system consists of several main functions: display of five major Korean petrochemical complex layout, display of equipment layout with its information utilizing the external database, zonation of the hazard effected area with consequence analyses, the most probable accident scenario generation, accident/incident database and calculation of frequency of accident using equipment reliability database, etc. The highlight of IRMS is to provide the risk contours using GIS(Geographical Information System) technology. IRMS is intended to manage hazardous installation more systematically and effectively, to reduce the number of accident remarkably, further minimizing production loss in the plant. The system is now under application to about 500 PSM sites as well as and emergency authorities in Korea by KOSHA (Korea Occupational Safety and Health Agency)

측핵과 편도체 중심핵이 조건공포의 습득과 파지에 미치는 영향

권혁철 한국심리학회 한국심리학회지 생물 및 생리 Vol.6 No.1

편도체 중심핵의 손상과 측핵의 손상이 조건공포의 습득과 파지에 주는 효과를 알아보았다. 편도체 중심핵 손상 집단의 지렛대 누르기에 있어서의 억압률을 모의시술-조건형성 집단과 모의시술-통제 집단의 억압률과 비교하였다. 측핵 손상 집단에 대해서도 각기 동일한 비교를 하였다. 편도체 중심핵 손상 집단의 조건공포 습득에 있어서의 결함이 나타났고, 측핵 손상 집단에서도 동일한 결함이 있었다. 이러한 결과는 편도체 중심핵이 동기적으로 중요한 자극들 사이의 연합의 형성과 유지에 있어 매우 중요하며, 중뇌변연 도파민계가 동기적으로 중요한 자극에 의한 행동의 활성화에 관여하고 있음을 지지해 준다. This study examined effects on acquisition and retention of conditioned fear of nucleus accumbens(n.Acc) lesion and central amygdaloid nucleus(ACe) lesion. The suppression ratio in bar-pressing of ACe-lesioned group was compared with that of Sham-Conditioning group and Sham-Control group. In n.Acc groups same comparisions were made respectively. If was found that ACe-lesioned animals and n.Acc-lesioned animals showed the deficit in acquisition of conditioned fear. It was suggested that ACe seemed to be essential in the formation of associations between motivationally significant stimuli and that mesolimbic dopamine system was involved in the activation of behavior by motivationally significant stimuli.

The following results were gathered from the extensive research done on the conduct disorder of patients improving and relative conditions. 1. All were good students in elementary school and showed no disobedience. 2. The majority of them had many strong relationships and were very outgoing. 3. Their parents showed much affection toward them in their childhood. Also, they were either the youngest or the oldest in their families consisting of 2 or more. 4. Five out of the 6 patients belonged to upper-middle or just upper class parts of society. 5. Fathers occupied professional occupations and the mothers occupations were domestic housekeeping. 6. They all had parents who were both well educated. 7. The patients attitude toward their parents changed from assertiveness ot obedience and respectfullness. 8. The degree of educational interest by their parents was very high ; 4 out of 6 9. Parents attitudes toward their children changed from traditional to democracy. The family relationship situation was deterioration. Then overtime, the situation inproved dramatically. 10. Parents method of punishing children seems to have changed from the tendency of tough punishment and patients respectful attitude toward their parents has changed from assertive to obedient. 11. There was no history of mental disorders in the family. 12. Most patients had jobs or continued their studies. 13. Conduct disorders occurred in these patients in their late teens. 14. They have never been imprisoned or placed in a mental hospital before.

[1, 3]-OH 시그마 결합 자리옮김 반응에 관한 이론적 연구

오혁근,조인호 全北大學校 基礎科學硏究所 1987 基礎科學 Vol.10 No.1

The MNDO semiempirical MO method was used in determination of transition states and activation energy for [1,3]-OH sigmatropic rearrangement in 2-pro-pen-1-ol. Calculated results were also compared with [1,3]-H and [1,3]-CH_3 sigmatropic rearrangements. Considering of steric effect, bond order, Ao coefficient, and charge dispersion [1,3]-OH shift was found to be favorble than [1,3]-H and [1,3]-CH_3 shifts. We found that non=planar transition state of [1,3]-OH shift had lower energy barrier than planar transition state due to the stereoelectronic effect.
