물관리방법을 달리한 상시담수와 간단관개에서 메탄과 아산화질소의 배출 양상과 서로 다른 종류의 유기물원 및 질소비료 시용에 따른 메탄과 아산화질소 배출을 비교하고 저감 할 수 있는 방법을 찾기 위해 본 시험을 실시하였다. 물관리방법으로는 상시담수 (이앙∼출수 35일까지 담수)와 이앙 35일 이후 중간낙수한 간단관개 (중간낙수기간 20일),그리고 시비방법으로는 토양을 검정한 시비량인 토양검정, 토양 검정시비량+볏짚 돈분액비, LCU 완효성비료 그리고 N을 시용하지 않은 대조구 등을 처리하여 메탄 및 아산화질소 배출량을 측정하였다. 메탄 배출량은 간단관개보다 상시담수에서 높았고, 아산화질소 배출량은 이와 반대로 나타났다. 유기물과 비료시용 종류에 따른 메탄과 아산화질소 배출량은 액비와 검정시비+볏짚시용구에서 가장 높았으며, LCU 완효성비료구에서 가장 낮았다. 지구온난화잠재력으로 환산한 온실가스 배출은 물관리 조건에서 상시담수가 간단관개보다 170∼208% 높았으며, 요소를 시용하고 상시담수를 기준 한 것과 간단관개로 물 관리하여 각 처리에 따라 온실가스 배출을 비교하면 요소는 41.4%, LCU 완효성비료 55.8%로 온실가스 배출을 줄일 수 있는 것으로 나타났다. 그리고 비료이용효율은 LCU완효성비료, 액비>검정시비+볏짖>검정시비 순이었다. Emission of methane and nitrous oxide affected by nitrogen fertilizer materials were measured simultaneously in rice paddy fields under flooding and intermittent irrigation in 2000. Studies focused on mitigating CH_4 emission from rice paddy fields are summarized and the possibilities and limits applied to world's rice cultivation are discussed. The mitigation options are water management, soil amendments, organic matter management, different tillage, rotation, and cultivar selection. Altering water management, in particular promoting midseason aeration by short-term drainage, is one of the most promising strategies, although these practices may be limited to the rice paddy fields where the irrigation system is well prepared. The test site was divided into two water managements: a continuously flooded plot which was maintained flooded by constant irrigation from May to September, and an intermittently drained plot in which short-term (20days) draining practices were performed one times during the flooding period. By total emission of GHGs converted by global warming potential (GWP), flooding plots were higher 170~208% than intermittent irrigation plots. For emission of GHGs in fertilizer materials, it was high in the order of Swine slurry>Urea+Rice straw>Urea>LCU. Basing on GHGs emission of urea fertilization under flooding as baseline GWP of urea fertilization and Latex-coated urea under intermittent irrigation showed lower GHGs emission by 41.4% and 55.8%, respectively. In this case fertilizer use efficiency (kg unhulled rice/kg of applied N) were 18.2~20.2 and 18.7~19.0 and 9.3 and 5.8~6.6 for Swine slurry and LCU and Urea+Rice straw and Urea in the continuously flooded and intermittently drained plot.

맥베드 (Macbeth) : 세 마녀의 대사와 생성의 원리 Weltsanschaung of Becoming

김헌범 제주한라대학 2002 論文集 Vol.26 No.-

The aim of this paper is to throw some light on Shakespeare's Weltsanschaung reflected in Macbeth through the examination of the play under the supposition that "Fair is foul, and foul is fair" is relevant not only to the themes but to the explanation of the characters' motif. This prophetic dialogue is to be understood in terms of the dynamic cooperation of contrasting elements in order to have its significance in its relation to the meaning of the play. That is, this play should be interpreted and understood in terms of the dynamic theory of 'Becoming', not in terms of the static theory of 'Being'. In this context the supposition can be of help delving into the deep Weltsanschaung of Shakespeare's Macbeth. The characters and their actions are variations on the supposition, 'Fair is foul, and foul is fair.' The 'is' in this supposition signifies the dynamic cooperation of the two contrasting elements, and suggests the importance of the role of human consciousness in their relation. The movement of Macbeth's action and the judgement on his own actions implies that he shall be understood in the vertical movement of this consciousness and will. This is the point which is necessary for the ironies to come to be. The same can be applied to Malcolm and Macduff, which proves the authenticity of the supposition. This viewpoint proves true in that Macbeth's nature was evil from the beginning to Lady Macbeth's dialogue and an analysis of his solioquies. This also proves that emphasis is put on the dynamic process of Macbeth's consciousness rather than on the moralistic didacticism, which one of the main themes of the play, including that this is the very nature of the world in which man and the universe exist. This is, too, one of the main causes which arouse the pity and sympathy in the hearts of the audience. As a conclusion, the principle of Becoming implicated in 'Fair is foul, and foul is fair' is that man is set in the dynamic process of the world. This monistic principle does not deny Shakespeare's tragic vision that there is more than man can imagine and know in the universe, rather it cooperates to add a wider range of perspectives to the understanding of Shakespeare's Weltsanschaung putting emphasis on the deep vertical movement of human souls.

To develop the biomarker of non-invasive biomonitoring among workers who exposed benzidine-based dyes in its manufacturing and treating industries, we examined and evaluated the specific carciaogen-DNA adducts in exfoliated urothelial cells of 33 exposed workers. Samples were collected from urine of workers, and then isolated DNA from them. DNA adducts were analyzed using 32P-postlabeling, along with Nuclease P1. One adducts was predominated in those samples with 6 adducts present. It was formed in all exposed workers, but the others not. Its relative adducts level(RAL) was 73.2×107, which was statistically significantly higher than any other adducts' level(p<0.05). Analyzing regression between its RAL and employment period of workers, simple linear regression was positively increased with slop of 6.922(p<0.05, r2=0.548). And also, DNA adducts were analyzed using GC/MS-SIM, along with n-butanol extraction and trifluoroacetyl auhydride(TFA) derivatization. Standard material was synthetic N-(deoxyguanosin-8-yl)-N'-acetylbenzidine. The characteristics of sample and standard were observed on the same sites, such as M+(m/z 376) and M+(m/z 279) for benzidine-di-TFA and mono-TFA. And then, they were confirmed by analyzing with secondary ion mass(SIM). This study showed that benzidine-based dyes was formed one DNA adduct into significantly high levels in bladder of all exposed workers, its chemical formula was N-(deoxyguanosin-8-yl)-N'-acetylbenzidine. So we can do monitoring the workers with exfoliated urothelial cells of them by analyzing above DNA adduct as biomarker for preventing bladder cancer causing the exposure of the benzidine-based dyes.

She admitted to CNU hospital with major complaints of fever, skin rash, and gastrointestinal symptoms. Litter in the course, periungal desquamation developed, mimicking Kawasaki disease. Treatments with antibiotics improved the conditions and serum examination revealed the Yersinia pseudotuberculosis 4a, 4b infection.

콩에서 발생하는 강낭콩일반모자이크바이러스(BCMV)와 땅콩위축바이러스(PSV)의 저항성 평가

이영훈, 윤영남, 강범규, 김현영, 최만수, 구성철, 김현태, 윤홍태, 이수헌, 백인열 忠北大學校 農業科學硏究所 2014 農業科學硏究 Vol.30 No.2

It has been reported several viral diseases in soybean. The occurrence of Bean common mosaic virus and Peanut stunt virus are able to induce severe problem because the main breeding target for viral disease was focused on Soybean mosaic virus. BCMV is a spcies of the genus Potyvirus of the family Potyviridae. BCMV reduces yield by as much as 80% and also adversely affects seed quality in common bean. BCMV has a worldwide distribution because of its high rates 35% of transmission via seeds produced by plants systemically infected prior to bloom. PSV is a species of the genus Cucumovirus of the family Bromoviridae. PSV has been reported to be economically damaging on beans worldwide. Although the virus is reportedly seed transmissible at very low rates, infected plants rarely produce pods with normal viable seeds. The most satisfactory management method of viral diseases such as BCMV and PSV is the use of resistant cultivars and healthy seed. For the overcome of genetic resistance by new virus such as BCMV and PSV, virus diseases monitoring and researches need to study deeply and continually. In this study, we conducted the resistance screen on BCMV and PSV for selection of resistance cultivars. We inoculated on 128 cultivars with PSV and BCMV respectively. These cultivars were classified through pathogenic response such as resistance, necrosis and susceptibility. In addition, 99 and 66 resistant cultivars were confirmed against PSV and BCMV respectively.
