한우의 간 조직에서 성장단계별로 발현하는 유전자의 분리

윤혜숙,구용범 인제대학교 1998 仁濟論叢 Vol.14 No.1

생명체에서 발현되어지는 여러 종류의 유전자들은 조직 특이적으로, 흑은 성장단계별로 다른 발현 양상을 보인다. 한우의 경우에서도 그 발현 양상이 다른 유전자가 있을 것으로 추정된 바, 한우의 간 조직을 이용하여 성장단계별로 그 발현 정도가 다른 유전자를 탐색하고자 하였다. 성장단계에 따른 유전자 발현의 차이는 생시, 6개월, 12개월, 24개월 된 한우의 간 조직에서 합성한 cDNA의 subtraction과 PCR 방법을 이용하여 탐색하였다. PCR로 증폭한 cDNA library에서 임의적으로 선택한 622개의 clone들을 slot-blot hybridization를 이용하여, 간 조직의 성장단계별로 차이가 나는 140개의 clone을 얻었으며, 140개의 clone 중 101개의 clone은 성장단계가 증가할수록 발현 양상이 점차적으로 증가하는 유전자인 반면, 39 개의 clone에서 얻은 유전자는 태어난 후 6 개월 이내에 급격히 발현이 증가하는 양상을 보였다. 점차적인 증가 양상을 보인 유전자들을 조사한 결과, 생체 내에서 유해한 free radical로부터 조직이나 세포 구조의 손상을 방지하는 역할을 하는 유전자들과 지방의 생합성 및 지방산이나 지방의 이동과 관련이 있는 유전자들인 것으로 생각되어진다. In many organisms, many genes are expressed differentially depending on developmental stages and ages. It was believed that some genes are expressed differentially in bovine liver tissue during growth. To analyzed the differentially expressed genes, cDNAs from bovine liver tissues of 0, 6, 12, 24 months old oxen were used for cDNA subtraction and PCR. 622 clones were randomly selected from the subtracted cDNA clones and were used for slot-blot hybridization to screen the clones showing differential expression. 140 clones out of 622 were found to exhibit different levels of hybridization signal to the cDNA probes prepared from liver tissues of different growth stages. Of 140 clones, 101 clones exhibited incremental expression during postnatal growth up to 24 months, whereas the 39 clones showed abrupt increase in expression within 6 months of age. It seems that some of the genes which showed gradual increase in expression during growth are related to removal of free radicals, and the others are related to biosynthesis or transport of lipids. Key words : cDNA subtraction, bovine liver, differential gene expression.

Ribbon형 Co1-x Crx (x=0.27, 0.29, 0.30, 0.32, 0.35) 합금의 자기특성

장현숙,김미양,이장로,이용호 숙명여자대학교 자연과학연구소 1994 자연과학논문집 Vol.- No.5

급냉법으로 리본형 결정질 Co1-x Crx (x=0.27, 0.29, 0.30, 0.32, 0.35)합금을 제조하여 Cr의 조성에 따른 자기적 특성을 조사하였다. 포화자화값은 벌크값보다 컸지만 박막의 경우보다는 작았다. Cr의 함량이 증가함에 따라 포화자화값은 감소하였다. 27 at.% Cr의 경우를 예외로 하면 Cr 함량 증가에 따라 결정립의 크기는 감소하였고, 항자력은 증가하였다. 리본형 Co1-x Crx 는 포화자화값의 온도 의존성이 비정질 시료인 경우와 유사한 경향을 나타내었으며 Cr의 함량이 증가할수록 Curie온도(Tr)는 감소하였다. Cr 함량의 증가에 따라 exchange interaction의 평균자승거리<r²>와 spin wave stiffness 상수D는 감소하는 경향을 나타내었다. 천이금속(Co)의 원자당평균 자기모멘트는 Cr의 증가에 따라 선형적으로 감소하였다. The magnetic cnaracteristics of crystalline Co1-x Crx (x=0.27, 0.29, 0.30, 0.32, 0.35) ribbons prepared by the rapid solidification were investigated. The saturation magnetization for ribbon was greater than that for bulk alloys containg the same amount of Cr. but smaller for the films. The grain size of ribbon became smaller and coercive force increased with increasing Cr contents except case of 27 at.% Cr. The saturation magnetization decreased with increasing Cr contensts. The temperature dependence of saturation magnetization for Co1-x Crx ribbon showed the similar behavior as the amorphous alloy and the Curie temperatures were decreased with the increase of Cr contents. The spin wave stiffness constant and the mean square range of exchange interaction, also were decreased. The average magnetic moment per transition metal atom was linearly decreased with increasing the contents of Cr.

甚한 惡液質을 同伴한 若年性 進行痲痺 (晩發性 先天梅毒) 1例

田珍淑,朴容九 大韓神經精神醫學會 1988 신경정신의학 Vol.27 No.4

A 15 year-old boy, who had been ill in bed with pervasive cognitive impairment, poor intelligence, global aphasia, disuse muscular atropy, etc since the age of 11 years is reported under the impression of juvenile general paresis. His mother and an elder brother also had positive responses to serologic tests for syphilis. Brain computed tomography showed marked dilatation of ventricles without sulcal enlargement, which was interpreted as communicating hydrocephalus rather than cerebral atropy. He showed some improvements of intelligence and cognitive functions after intramuscular penicillin administration and ventriculoperitoneal shunt. However, it was not good enough to say that his daily living activities in general had improved.

The purpose of this research was to analyze the effects of situation-related anxiety(SRA) on academic achievement of subject-matters of elementary and secondary school students(N=828), and the research problems were as follows; 1) What correlations are there between SRA's sub-factors(such as home-related anxiety; HORA, school-related anxiety: SCRA, examination-related anxiety: EXRA, and society-related anxiety: SRA) and academic achievement of subject-matters? 2) What the combined and relative effects are there SRA's sub-fectors on total academic achievement(TAA)? 3) What the combined and relative effects are there SRA's sub-factors on academic achievement of subject-matters? 4) What the combined and relative effects are there variables(items) in SRA's sub-factors on academic achievement of subject-matters? The subjects for this research were 828 and selected randomly from each level of school such as primary(199), middle(313), high(316) schools in Seoul. And the instruments used for the research were "Situation-Related Anxiety Scale" (Kim, Y.R. & Koo, s.S., 1989) and "Teacher-made Test". The collected data were analyzed statistically through SPSS program-simple correlation, multicorrelation, and regression analysis. The major findings of this research were as follows; 1) The correlation coefficient between SRA and each subject-matters' academic achievement and TAA was -.1914∼-.2414(p<.001), and the correlation between SCRA and each subject-matters' AA and TAA was statistically significant proved negative(-.2570∼-.3060, p<.001). 2) The R^2, the combined effect of SRA sub-factors on TAA 15.64%, and there were significantly relative effects of SRA sub-factors on TAA respectively(SCRA:9.37, SORA:3.19, HORA:2.30, and EXRA:0.78, p<.05). 3) The combined effect of SRA's sub-factors on subject-matters' academic achievement(SMAA) were 13.0%(Language), 11.0%(English), 11.0%(Mathematics), 13.12%(Social studies), and 11.44%(Morals) respectively. 4) The high effects-variabls(items) in SRA's sub-factors on SMAA were as follows: a) The high effects variable in HORA was "parents' non-recognition for children's ability" and the relative effects of this variable were 7.53%(TAA), 4.20%(Language), 4.47(English), 6.23%(Mathematics), 4.88%(Social studies), and 3.78(Morals). b) In case of SCRA, the relative effects of variable "my academic achievement opening" on SMAA were 8.95%(TAA), 7.71%(Language), 7.73%(English), 6.96%(Mathematics), 6.94%(Socal studies), and 6.51%(Morals). c) In the case of EXRA, ⑴ the relative effect of variable-"incapacity in exam-time" on Morals-SMAA was 5.32% and ⑵ the relative effects of variable- "presenting my academic achievement to parents" TAA and SMAA were 8.04%(TAA), 6.68%(English), 6.27%(Mathematics), 5.75%(Language), and 5.43%(Social studies). d) In the case of SORA, ⑴ the relative effects of variable- "frequent traffic accident" on TAA and SMAA were 2.14%(TAA), 2.02%(English), and 1.89%(Mathematics), and ⑵ the relative effects of variabls- "reception of intemperate foreign culture and goods" on SMAA were 1.95%(Language), 1.80%(Social studies), and 1.70%(Morals).

This study was conducted to find out the occurrence of pests and yield performance of rice by pesticide spray or non-saray and application of organic matter, such as rice straw compost, fowl dung compost, rice straw + SEMIP(super effective micro-organism in plantation), organic fertilizer and milk vetch. The contents of 0.M and C.E.C were increased a little in soil applied with organic matter. At the one panicle formation stage the contents of T-N of rice leaf blade and leaf sheath in conventional plot were lower than that in applied organic matter plot. The occurrence of pests in pesticide non-spray was much more than that in pesticide spray. Rice plant was damaged by sheath blight in every kinds of organic matter of pesticide non-spray plot. Therefore sheath blight must be applied by chemicals. The damage of rice stern borer was high in plots of fowl dung compost, organic fertilizer and milk vetch of pesticide non-spray plot. The contents of protein in conventional plot were 5.18-5.24%, but 5.41-5.89% in applied organic matter plot. Percentage of ripened grain in pesticide non-spray(83.6-86.9%) was lower than that in pesticide spray (88.0-89.7%). The yield of brown rice in pesticide non-spray was 13% lower than that in pesticide spray.

The present study achieved the following conclusion by analyzing of theoritical adventure experience paradigm and the model of flow which require a risk experience in leisure and sport. 1. The influience of emotion on the experience of risk dependons upon the situation of risk and ability one's competence. 2. From the fact that those who maintain the optimal state through the high arousal is deduced by the effect of social environment with special factors. 3. People can experience a peak adventure, perceiving correctly one's competence in a risk situation. 4. It appears that risk in adventure experience(eustress and distress, risk/dange rs, social orientation or environment orientation and spectively) associate the erception of competence(attitude and ability, skill/experience level, frequency of participation, locus of contrl)multidimentionally. 5. It is possible that the optimal experience about the adventure leisure and sport could be achived by equalizing the desire of challenge with competenceto the optimal situation for challenge. 6. The critical factor on the enjoyment is the variance of one's competence, and therefore it is possible that the perception of high competence makes it controlthe degree of difficulty in a risk situation. 7. The future research requires experimental study on the manner of participan ts and the optimal experience on the adventure leisure and sport.
