조윤선 ( Yun Seon Cho ) 글로벌기독교세계관학회 2010 학문과기독교세계관 Vol.1 No.-

The primary purpose of this paper is to assess the social environment and people`s ideology, life style which were the period of previous modern age. At that time the Protestant was not still spreaded in the Cho-seon dynasty, but on the other hand the Confucianism was general tended since the 17th century. It was the common thing in those ages that the inequality was a heavy burden to the women and the slaves. Especially when the political party of the Noron took the helm of state, the inequality was deepened and the opposite political party of the Soron was more isolated. Because of those social atmosphere, they had been denied the existing social idea and as a result the standard of the social values were changed. And the changing of the social values were afforded an opportunity of the new religion Dong-hak which were emphasized the importance of the human rights and equality. In the same age eventually the Roman Catholicism were come to this country, Cho-seon. They took the new religions as a matter of course. Because they had declared themselves against the inequality, oppression and the irrational family system. The people who followed the new religion especially the Roman Catholicism believed the Cheon-Ju as one and only God instead the exciting King and the aristocratic class, Yang-ban. More and more they were inclined the new ideology which emphasized the equality of all kind of human. IThe more Roman Catholicism was spread out, the more religious persecution were happened. Lots of the believers were punished the death. At those times the case of the "Hwang-Sa Yeong`s letter on silk" was happened. Even though Hwang`s mainly attitude was toward the dependent on the western country`s power, we could find out the people who appeared on the letter were truly believer as the christian. The later period of the Cho-seon, the inequality was dominated over all kind of the society, and many of the catholic martyr and martyress made the finally the sacrifice the reception of Protestant.

Optimal Features for Classifying Giemsa-Stained Human Chromosomes with An Error-Backpropagation Neural Network

Cho, Jongman,Ryu, Seung-Yun 仁濟大學校 2006 仁濟論叢 Vol.21 No.1

Many studies for computer-based chromosome analysis using artificial neural network (ANN) have shown that it is possible to classify chromosomes into 24 subgroups. It is important to select optimum features for training the ANN. Our purpose was to select features that had the low classification error and the best ability for human chromosome classification. We applied the medial axis transformation for the medial line, extended the line to the boundary and obtained relative length, relative area and centromeric index. The Giemsa-stained human chromosome has a sequence of banding pattern that is perpendicular to the medial axis of the chromosome. Density profile is a one-dimensional graph of the banding pattern property of the chromosome computed at a sequence of points along the possibly curved chromosome medial axis. Some studied used relative length, centromeric index and 62 density profile as features, but we prepared two data sets as features that one set was relative length, centromeric index and 80 density profile considered No. 1 chromosome's length and the other was relative length, centromeric index, the 80 density profile and relative area and compared classification error of each set. We found that the classification error showed to be decreased by adding relative area to the other features.

‘금촌조생’ 품종은 농촌진흥청 원예연구소 나주배연구소에서 1971년 ‘금촌추’의 품질을 개선하기 위해 당도가 높고 육질이 유연한 ‘단배’를 교배하여 1982년 1차 선발되었고, 1997년부터 5년 간 지역적응시험을 거쳐 2001년 최종 선발 및 품종보호출원 되었다. 수세는 비교적 강하고, 수자는 반개장성이다. 꽃가루가 풍부하며, 주요 재배품종과 교배친화성을 보인다. 또한 흑반병에 대하여 강한 포장저항성을 나타내었다. 숙기는 재배중인 ‘원황’ 품종보다 약 5일 정도 늦은 9월 3일로 추석에 출하하기 알맞은 품종이다. 과형은 ‘금촌추’와 같은 도원추형이고, 과피색은 황갈색이다. 과중은 593g이고, 당도는 13.2Bx이다. 육질은 유연하며 과즙이 풍부하고, 석세포가 없어 식미가 매우 우수하다. 그러나 과육선숙형 품종으로 원예적 수확기에도 과피에 녹색이 남지만, 완숙과가 되면 황갈색으로 착색된다. 상온저장 기간은 20일 정도로 다른 조생종에 비해 저장력은 좋은 편이다. ‘Geumchonjosaeng’ pear cultivar (Pyrus pyrifolia var. culta Nakai) originated from the cross between ‘Imamuraaki’ and ‘Danbae’ to improve the fruit quality of ‘Imamuraaki’ cultivar in 1971 at Naju Pear Research Institute of National Horticultural Research Institute (NHRI), Rural Development Administration (RDA). It was preliminarily selected in 1982 and named in 2001. The tree habit shows vigorous growth and upright spreading. It carries abundant pollen grains and shows cross compatibility with leading cultivars. Also it shows high resistance to black leaf spot (Alternaria kikuchiana) in the field condition. Optimum harvest time is around Sep. 3, which is 5 days later than that of ‘Wonwhang’, and it could satisfy consumer’s demand for high quality pear fruit in “Chuseok”. The obovate fruit shape resembles maternal parent, ‘Imamuraaki’ and skin color is green yellowish brown at normal harvesting time and gradually turned to yellowish brown at full ripennig state. Fruit weighs about 593 g, and the soluble solid content is 13.5 ˚Bx. The flesh is very soft and juicy and, rendering good eating quality. Shelf life is about 20 days under the ambient temperature, and it is a relatively long period as compare with other early season cultivars.

조윤현 東亞大學校 大學院 1996 大學院論文集 Vol.21 No.-

This paper presents the design and characteristics analysis of induction machine for diesel-electric hybrid vehicle powertrain. diesel-electric hybrid vehicles are very efficacious in reduction of consumption energy, environment pollution and saftly yields with high dynamic ofr machines. However, their sophisticated construction requires from designers both complex made-technology and control strategy which would be able to put into practice this requirements. These problems are still considered in processing the design and analysis of induction machine. The requirements for a given volume, input power to weight ratio, high efficiency and wide speed range are met by the induction machine. The three phase induction machine with 12-pole, the maximum power, 34Kw and the maximum speed, 2300rpm is designed and manufactured. To investigate performance characteristics of the induction machine, the magnetic flux density is analyzed by the 2-dimensional F.E.M. and its performance is tested using the M-G dynamic tester. The experimental values are compared with the simulation ones. As a result of this work, it is found that good performances in terms of the efficiency, the primary current and the torque is obtained in the operation region of hybrid car, but no good performance occurs around the maximum speed region.

모잘록병균(Pythium ultimum)에 대한 N-Phenylbenzenesulfonamide 유도체의 살균활성에 미치는 구조적 특성

조윤기,장기운,성낙도 충남대학교 농업과학연구소 2008 농업과학연구 Vol.35 No.1

The structural characteristics that influence on the fungicidal activities of N-phenylbenzenesulfonamide (1∼24) and N-phenyltheinylsulfonamide (25∼30) derivatives against Dampping-off (Pythium ultimum) were discussed quantitatively using the models of molecular holographic quantitative structure-activity relationships (HQSAR). From the based on these findings, the statistical results of the optimized HQSAR F-3 model showed better predictablity (r² cv. or q²=0.581) and correlation coefficient (r²_(ncv).=0.963). And, from the analytical results of the atomic contribution maps on the fungicidal activities, the most active compound is R₁= 2-fluoro-4-chloro substituent (4) and the most inactive one is R₁=4-methoxy substituent (20). It was found that the 2-fluoro-4-chlorophenyl group as a R₁-group was an important structure and a characteristic factor not only for herbicidal activity but also for fungicidal activity.

조윤기,최우영,성낙도 충남대학교 농업과학연구소 2007 농업과학연구 Vol.34 No.2

The new insecticidal active molecules from the based on the holographic quantitative structure-activity relationships (HQSAR) between a series of 1-(R₁)-2-(n-octyl)-3-(R₂), 3-(R₃)-pseudothiourea derivatives and their insecticidal activities against Diamond-back moth (Plutella Xylostella Linnaeus) were designed and discussed quantitatively. The most active molecule from the based graphical analyses of atomic contribution maps with the optimized HQSAR C-1 model (q²=0.764 & r²_(ncv)=0.942) was 1-(n-butyl)-2-(t-butyl)-3,3-diisopropylpseudothiourea (P1: pI_(50)=5.30, IC_(50)=1.397 ppm). Therefore, it is suggested that the new designed molecule would increased the activity as much as 23.5 times as compared to X=n-octyl substituent 17(pI_(50)=4.00, IC_(50)=32.86 ppm) which was the highest active molecule in training set compounds.
