Migration-enhanced epitaxy 성장한 InAs/GaAs 양자점(quantum dots)의 광학적 특성을 PL (photoluminescence)과 Time-resolved PL 이용하여 분석하였다. InAs 양자점은 In을 9.3초 공급하고 5초 차단한 후 As을 3초, 4초, 6초, 또는 9초 공급하고 5초 차단하는 과정을 3회 반복하여 성장하였다. As을 3초 공급한 시료의 PL 피크는 1,140 nm에서 나타나고, PL 세기는 다른 세 시료에 비해 매우 약하게 나타났다. As 공급시간을 3초에서 증가하였을 때 모든 PL 피크는 1,118 nm로 청색이동하여 나타났으며, PL 세기는 증가하였다. As을 6초 공급한 시료의 PL 세기가 가장 강하게 나타나고, 반치폭(full width at half maximum)도 가장 좁게 나타났다. 이러한 결과는 양자점의 밀도와 균일도(크기변화)로 설명된다. 또한 발광파장에 따른 PL 소멸시간은 PL 피크 근처에서 가장 길게 나타났다. The luminescence properties of InAs/GaAs quantum dots (QDs) grown by a migration enhanced epitaxy method have been investigated by using photoluminescence (PL) and time-resolved PL measurements. The MEE method supplies materials in a series of alternate depositions with migration enhancing time between each deposition. After In source was supplied for 9.3 s, the growth was interrupted for 5 s. Subsequently, As source was open for 3 (AT3), 4(AT4), 6 (AT6), or 9 s (AT9), and the growth was interrupted for 5 s again. This growth sequence was repeated 3 times for the growth of InAs QDs. The PL peak of the AT3 was 1,140 nm and the PL intensity was very weak compared with that of the other three samples. The PL peak of all samples except the AT3 sample was 1,118 nm, which is blueshifted from 1,140 nm, and the PL intensity was increased compared to that of the AT3. These results can be explained by the increased QD density and the improved QD uniformity. The AT6 sample showed the strongest PL intensity and the narrowest full width at half maximum. The PL decay time of AT6 increased with increasing emission wavelength from 940 to 1,126 nm, reaching a maximum decay time of 1.09 ns at 1,126 nm, and then decreased as the emission wavelength was increased further.

Anthracycline계 항암항생제인 adriamycin투여에 따른 랫트 신장 독성을 투여 시간 경과에 따라, alkaline phosphatase, adenosine triphosphatase와 acid phosphatase의 활성 변화로 관찰하였다. This experiment was carried out to investigate the effect of adriamycin on renal alkaline phosphatase, adenosin triphosphatase and acid phosphatase in rat. The experimental animals were administered with single dose of adriamycin, Img/kg, by the intravenous injection. The following result were obtained 1.The alkaline phosphatase activity appeared to be moderately decreased in the proximal convoluted tubules at the 8 hours. This decrease maintained by the second day and recovered to the normal state at the fourth day. 2.The adenosine triphosphatase activity appeared to be moderately increased in the proximal convoluted tubules at the 12 hours This increase maintained by the eighth day. 3.The acid phosphatase activity is moderately increased in the proximal convoluted tubules at the 4 hours. This in crease maintained by the 18 hours and recovered to the normal state at the first day.

金雲汀 희곡 연구

李美媛 慶熙大學校 1989 論文集 Vol.18 No.-

Yunjeong Kim is one of the most important Korean playwrights in the 1920s. Because he once studied under 島村抱月, a pioneer of Japanese modern theatre movement, he understood the western dramatic conventions well and took advantages of them in his plays. Yunjeong's plays could be divided into three groups. The first group makes good use of dramatic conventions. "The Fifteen Minutes (십오분간)" is the most successful play of the group. It set up the un-realistic tradition of Korean drama. The plays of the second group are modern realistic plays. Many western realistic techniques such as using everyday language, detailed description of stage, avoiding catastrophic effect, are achieved in these plays. "A Whistle blows (기적불때)" is the best example of this group. It still remains to be a question whether the beginning of realistic drama is that of modern drama in Korea. This question is believed to be answered in relation to the beginning of Korean modern literary history. The plays of the third group arc understood in the light of Sinpa plays of his time. Sinpa plays are the Korean adaptation of melodrama. They emphasize sad sentiments and adapt some Japanese traditional acting styles such as Noh and Kabugi. In spite of Sinpa's popularity, it obstructed the development of Korean modern drama in the long run. Thus, the third group plays of Yunjeong have little historical importance and literary merits compared to the others. Indeed, Yunjeong Kim played very important role for the development of Korean modern drama by establishing the dramatic traditions of realism and anti-realism. It is only regretful that the plays of Yunjeong had not been widely known and performed in his time due to the lack of his personal contact with theatre performance groups.

This study was designed to investigate the combined availability for the DST and TRH stimulation test in psychiatric patients, especially depressive patients. DST and TRH stimulation test were performed in 70 inpatients at the Dept. of Neuropsychiatry of Ewha Woman's University Hospital, Seoul, from June 1987 to June 1988. The results were as follows: 1) In 30 depressives(group Ⅰ), 13 patients(43.3%) were categorized as nonsuppressors of DST and 14 patients(46.7%) were as blunted responder of TRH test. However, of 40 other psychiatric patients(group Ⅱ), 39 patients(97.5%) were categorized as suppressor of DST and 25 patients(62.5%) were as normal responders of TRH test. 2) In major depression, the mean serum cortisol level of post-DST was significantly higher than group Ⅱ. (P<0.01) 3) The mean serum cortisol level of the depressives was significantly higher than the other psychiatric patients. (P<0.01) 4) There was no stastically significant correlation between △max TSH and post-DST cortisol level. 5) As the result of discriminant analysis for the group Ⅰ and group Ⅱ, we have reached the final rule; -0.0266(△mas TSH) +0.3119(P-DST) -0.5993>0 belong to group V -0.0266(△max TSH) +0.3119(P-Dst) -0.5993<0 belong to group Ⅱ Following this final rule, the sensitivity of depression was 63.3%.

In this paper, we propose an expansion method of surface text patterns which are used by Question-Answering systems to solve the long-distance dependency problem. We use additional information to present discontinuous patterns. Also, the cost of the system could be reduced by simplifying the training process. In this paper we implement the system based on the new training method to expand the form of patterns without external tools or knowledge bases. We prove that our system is efficient and reliable by comparing it with the performance of existing systems by the precision and MRR which is an evaluation method at TREC.

新劇 形成期 演劇의 社會觀

李美媛 慶熙大學校 1988 論文集 Vol.17 No.-

The Korean cultural movements of the early 20th century tended to aim to enlighten the Korean people, who were facing social changes and the colonial period. The dramatic movement was not an exception. In fact, due to the nature of theatre which meets the audience directly, the edifying role in theatre was more emphasized and lasted longer than in any other cultural movement. As the Korean modern drama emerged, the edifying perspective of theatre became more evident. Owing to the rising of the performers social status, the intellingentsia came to join theatre and to publish its edifying role by the early 20s. This paper examined the views of theatres role in the 20s, represented by Yoon Packnam, Hyunchul, Kim Woonchong, Cho Chunkwang, Kim Woojin and Hong Haesong, the representative dramatists and the critics of the 20s. They, except Kim Woojin, overall insisted that theatre had to initiate the nation-wide cultural movements and bad to be the best way to enlighten people. However, Kim Woojin who fully understood the Western Modern drama denied the edifying role of theatre. His artistic miew on theatre was later realiaed in the 30s. It is strange to notice the insistence of the edifying role lasted longer in theatre compared with in the other genres of poetry and novel, which began to move toward the artistic lines in the 20s. This seemed due to the impersonating nature of theatre as well as the efforts to change the conventional contemptuous view on theatrical arts from Yi dynasty. Many early dramatists joined theatre in order to improve society under the colonial rules and got respects from the people. This edifying view of theatre was in a sense an obstacle to the development of the modern drama but helped to raise the social status of theatre and to popularize it.

백서 뇌의 Ciliary Neurotrophic Factor 발현에 관한 면역조직화학적 연구

천현미,이영호,김원식 충남대학교 의과대학 지역사회의학연구소 1997 충남의대잡지 Vol.24 No.1

It was reported recently that ciliary neurotrophic factor (CNTF) is mainly present in the Schwann cells and asrocytes and maintain the motor neurons in postnatal periods. But there is no detailed research about the localization of CNTF. Several articles showed that there were many regions which have CNTF positive neurons. To test the unsettled CNTF immunoreactivity, the immunohistochemistry with CNTF antibody (Research & Development of the BML, Japan) was performed in th erat brain. The adult female rats weighing aound 200g were fixed by perfusion and 40-㎛-thick frozen sections were taken, and perform CNTF immunohistochemistry. The CNTF immunoreactivity was observed in the astrocytes of the optic nerve, olfactory nerve, fimbriae of the hippocampus, internal capsule, and cingulum, and in the non-astrocytes of the pyramidal tracts, the ventral portion of the pontine nucleus, and the central portion of the medulla oblongata. These data show that CNTF immunoreactivities present mainly in the astrocytes between the nerve fiber bundles in the cerebrum and in the non-astrocytes of the brain stem.
