I already wrote a thesis about A Study of Ideologies and Stylistic Features of the Oral Narratives in a Collection of Lee, Duck Moo's Works(ChungJangKwanJunseo)" in The Classical Literature and Education Vol.11, (2006). At that time I held over a study of figure's episodes. So this essay is a series of the thesis. In this essay, I described his critical ideas about the figure's episodes of other people. I classified as the gentry's episodes and the common's episodes, and ones more classified these as the Confucian's moral episodes and the oddity's strange episodes. And I studied the narrative principles and features of narrative structure. He asked for a reasonal thinking attitude in the figure's episodes of other people. In his the gentry's episodes he indicated as a important value the constant attitude of propriety and dignity. The other hand, in his the common's episodes he thought importantly a practical act of the Confucian's moral. He showed man's equality and criticized the anti-practical attitude of the gentry group. In the oddity's strange episodes were focused on the super ability of figures in the both of groups. And then even though there are unreal or unreasonable contents in the oddity's strange episodes, he did not criticize. His such attitude was came out to take interest in unreal story like the Paesasopeum(稗史小品). The the narrative principles of his episodes are two types, one is a summary or a report type, the other is a descriptive of events type. the former was explained by narrater, the latter was described as the indirect or direct narration of the characters. In the structure of narrative in case a summary type were enumerated with the episodes, but in case a report or descriptive type of events were contrasted with characters. A story-telling way of figure's episodes borrowed from 'Jeon(傳)' or 'Yadam(野談)' genre. And a point of view in case a summary or a report type was consisted with a center of narrater, in case a descriptive of events type was consisted with a center of witness.

This experiment was carried out to examine ecological response and soybean quality as affected by environmental cultivation for producing high seed quality in domestic soybean variety. The results are as follows: Under equal cumulative temperature condition, soybean plants grown in Muju showed longer days to flowering, which was an effect of the long day-length on high latitudes, and longer duration of reproductive stage as a result of low temperature within that period. Considering apparent seed quality, 100 seed weight of soybeans grown in Muju was heavier than Miryang. Ratio of seed crack and disease-damaged seeds was lower in Muju, and these parameters decreases as planting was delayed. The protein contents did not show significant difference in terms of altitude and planting date, however, crude oil contents were higher in Miryang. An opposite trend was observed in C18:1 and C18:3. In the fatty acid composition, the proportion of C18:1 decreased as seeding date was delayed, and was higher in Miryang. Opposite observations were obtained from C18:3. The anthocyanin contents were highest on June 10 planting and higher in Muju than in Miryang. Isoflavone content was higher as seeding date was delayed and is similar accross seeding dates in Muju. As a summary, for high seed quality production the optimum planting date was June 10, and Muju was more suitable region than Miryang.

The effects of 5 novel hepatotrophic agents, dithiol malonate derivatives (DMDs; DMD1-DMD5), on the liver microsomal lipid peroxidation induced by carbon tetrachloride $(CCl_4)$ and the correlations with the changes of microsomal electron transport system were investigated. All DMDs were found to inhibit the lipid peroxidation induced by $CCl_4$ in mice and rats as well in vitro liver microsomal system. Therefore, each DMD seemed to have direct mode of action on liver microsomes to inhibit the lipid peroxidation. As an ex vivo study, the induced lipid peroxidation by $CCl_4$ and the changes in electron transport system were determined with liver microsomes obtained from rats chronically treated with DMDs for 7 days. The induced lipid peroxide contents in liver microsomal system were lower in DMD1, DMD2 and DMD3 treated group, but higher in DMD4 and DMD5 group when compared to the control group. Cyt. p.450 contents in the microsomes were decreased by the treatment with DMD1, DMD2 and DMD3, but increased significantly by DMD4 with great extent and by DMD5 with less extent. The cyt. p-450 isozymes induced by treatment of DMD4 and DMD5 were identified as 3-methylcholanthrene (MC) type. The NADPH cyt. -C reductase activities of the microsomes treated with DMD1, DMD2, DMD4 and DMD5 were increased in the range of around 20% to 50%, but decreased with DMD3, All DMDs increased dyt. $-b_5$ content and did not alter NAdH-cyt, $-b_5$ reductase activities in the microsomes. In summary, the 5 novel hepatotrophic agents (DMDs) markedly protected against lipid peroxidation induced by $CCl_4$ in vivo and in vitro possibly through the mechanism of direct action on the liver microsomes. The degree of inhibition produced by DMDs on lipid peroxidation induced by $CCl_4$ seemed to coincide rather with cyt. p-450 contents than with other components of liver microsomal electron transport system including NADPH-cyt, -C reductase.

가상현실을 이용한 체험교육은 몰입을 통한 학습 효과성을 검증하며 의료분야에서 적극적으로 활용되고 있으나 가상현실 내에서 학습 몰입에 영향을 미치는 요인에 관한 연구는 부족한 실정이다. 이에 본 연구는 문헌 연구를 통해 인터페이스의 사용성 및 인지적 어포던스 평가 요소를 추출하고 가상현실 의료 콘텐츠 4종을 선정하여 전문가 대상 사용성 평가를 실시하였다. 이를 종합하여 가상현실 의료 술기 콘텐츠에 따른 인터페이스 설계 방안을 제안하였다. 내용을 요약하면, 정보를 제공하는 인터페이스는 가시성, 체험자의 시선과의 거리, 색감의 조화, 통일감 있는 시각화, 피드백, 반응 속도, 조작에 따른 예상된 변화로 인해 몰입에 영향을 끼치며 인터페이스를 통해 제공하는 정보의 의미와 용어가 명확해야 몰입을 해치지 않음을 알 수 있었다. 본 연구는 제한된 콘텐츠를 이용하여 일반화에는 한계가 있어, 이후 지속적인 연구를 통해 체험자가 학습의 맥락을 익히고 파악하기 위한 인터페이스 설계에 표준화된 가이드 개발 및 사용자 관점의 인터페이스 설계 연구에 대한 정밀화가 논의되기를 기대한다.

In order to evaluate the degree of air pollution, soils from 125 and 60points of main streets of Seoul and Daejeon, respectively, were sampled and analyzed for the contents of lead, copper, iron and zinc by nitric acid($HNO_3$) extraction followed by atomic absorption spectrophotometry during June and September, 1990. The Pb contents of Seoul and Daejeon were 350.2$\mu$g/g and 175.9$\mu$g/g, respectively, which were 14.5times and 7.3times respectively higher than the control(24.0). In Seoul, the commercial area gave the highest value followed by resdential and industrial areas in the decreasing order, while the order in Daejeon was Industrial, commercial and residential areas. The Cu contents in Seoul and Daejeon were very similar(236.6 and 234.6, respectively) each other, and about 11times higher than the control(20.9). The concentration was highest in industrial, followed by commercial and the lowest in residential areas in Seoul, while the order in Daejeon was industrial, residential and commercial areas. The Fe contents were 25716.5 in Seoul and 22838.6 in Daejeon, both being similar to the control value(22537.0). The value was highest in industrial and next in commercial areas and the lowest in residential area both in Seoul and Daejeon. The Zn contents in Seoul and Daejeon were 728.2 and 404.0, respectively, wihch were 6.3 and 3.6times higher than the control(113.3). The value was highest in commercial and next in industrial areas and the lowest in residental area in Seoul, while the order was industrial, residential and commercial areas in Daejeon. The heavy metal content was higher in the soil of main streets than that of minor streets in Seoul. The content of lead in Seoul was higher in the streets of Chongro-ku(525.9) and Chung-ku(684.8), the central area of the city which had a heavy traffic, than those in Nowon-ku(320.3) and Kwanak-ku(312.6) which had relatively less traffic crowd. The similar pattern was observed in the content of zinc; it was higher in Chongro-ku(1305.0) and Chung-ku(1335.4) than in Nowon-ku(489.1) and Kwanak-ku(569.8). In Daejeon, the contents of lead and zinc were decreasing as the distance from Daejeon Railroad Station increased : they were respectively 157.8 and 447.7 within 2km from the station, 157.6 and 235.7 with in 2-4km, and 63.5 and 156.2 within 4-6km and 58.7 and 142.2 within 6-8km. In summary, the contents of lead, copper and zinc were generally higher in the central area of the city, areas of heavy traffic and areas of industry and commerce.
