The purpose of this study were to identify school uniform satiafaction factors and to compare parents, teachers, and students' middle and high school uniform satisfaction. Respondents were middle and high school parents, teachers, and students in Chonbuk province and data was collected during March, 2002. Frequencies, percentages, and mean were calculated. ANOVA, Chi-square test, reliability test were done. The results were as follows: 1. The school uniform satisfaction was composed of 5 factors symbolism, design, management and comfort, durability and economy, and fitness. The satisfaction level of symbolism was the highest, and the management and comfort was the lowest. 2. The school uniform satisfaction level was relatively low. Teacher's school uniform satisfaction level was the highest, and students' satisfaction level was the lowest. The parents' satisfaction level of management and comfort, durability and economy, and fitness were the highest, and the teachers' satisfaction level of symbolism and design were the highest. 3. The parents and teachers' satisfaction level of symbolism and students' satisfaction level of school uniform design were higher under the strict school regulation on school uniform. parents, teachers, and students who agreed to the school uniform policy showed higher school uniform satisfaction.

완전 결합형 ATM 스위치의 멀티캐스트 성능특성에 관한 연구

전용희,박정숙 대구효성가톨릭대학교 응용과학연구소 1997 응용과학연구논문집 Vol.5 No.-

In this paper, we studied on the multicast performance characteristics of fully-interconnected switch proposed by ETRI. It is the proper architecture for a small-sized switch element. The switch uses bit addressing method for addressing scheme and thus it is easy to implement multicast function without adding a function block. In B-ISDN(Broadband Integrated Services Digital Networks), the efficient implementation of multicase function is very important since the demand for distributed type of service is expected to grow. To incorporate the bursty nature of traffic in ATM networks, we used IBP(Interrupted Bernoulli Process) model as an input traffic model. We presented and analyzed the simulation results in terms of the multicast operation of the switch.

Sprague Dawley계 숫 흰쥐에 eicosapentaenoic acid 및 docosahexaenoic acid둥 고도불포화지방산을 함유하고 있는 말쥐치커기름과 monoenoic acid를 많이 함유하고 있는 올리브기름을 각각 10% 씩 첨가하고 또한 vitamin E를 식이 100g당 5, 50, 100 I. U.로 첨가한 사료로서 2주간 사육한 후 혈청 및 간장 중의 cholesterol 농도, 과산화지질 및 α-tocopherol의 농도를 측정한 바 다음과 같은 결과를 얻었다. 1. 증체량 및 사료섭취량은 전 시험군 간에 있어 유의적인 차이는 없으나 말쥐치기름 투여군이 약간 낮은 경향이었다. 2. 혈청 중의 총 cholesterol 농도는 올리브기름 및 말쥐치기름 투여 군 모두 vitamin E의 첨가량을 증가시킴에 따라 낮아지는 경향이었으며, 말쥐치기름 투여군 은 올리브기름 투여군에 비해 유의적으로 그 농도가 낮았다 (P<0.05). 3. 혈청 중의 HDL-cholesterol 농도 및 총cholesterol 농도에 대한 HDL-cholesterol 농도의 비율은 말쥐치기름 투여군이 올리브기름 투여군에 비해 대체로 높은 경향이었다. 4. 간장 중의 총 cholesterol 농도는 말쥐치기름 투여군이 올리브기름 투여군에 비해 약간 낮은 경향이었다. 5. 혈청 및 간장 중의 과산화지질의 농도는 말쥐치기름 투여군이 유의 적으로 높았으며 (P<0.05) vitamin E의 첨가량을 증가시킴에 따라 감소되는 경향이었다. 6. 혈청 및 간장 중의 α-tocopherol 농도는 말쥐치기름 투여군이 유의적으로 낮았다 (F<0.05). The Sprague Dawley male rats were fed experimental diets containing 10% file fish oil or 10% olive oil, and three graded levels of vitamin E(5,50 and 100 I.U./l00g diet) were provided for each test oil group. After two weeks feeding, the concentration of cholesterol, lipid peroxide and a-tocopherol in serum and liver of rats were determined. The results were summarized as follows. 1. The amount of body weight gain and food intake of rats were not significantly different among all the experimental groups but tended to slightly be low in rats fed file fish oil diet. 2. Total cholesterol concentrations in serum tended to be decreased as vitamin E level increased all of the file fish oil and olive oil diet groups, serum total cholesterol concentrations of the file fish oil diet groups were significantly lower than those of the olive oil diet groups. 3. HDL-cholesterol concentrations and the ratio of HDL-cholesterol to total cholesterol in serum generally tended to be higher on the file fish oil diet groups than those of the olive oil diet groups. 4. Total cholesterol concentrations in liver tended to slightly be lower on the file fish oil diet groups than those of the olive oil diet groups. 5. Lipid peroxide values in serum and liver were significantly high on the file fish oil diet groups and tended to be decreased as vitamin E level increased. 6. The concentrations of α-tocopherol in serum and liver were significantly low on the file fish oil diet groups.

홍용표,오승환,라미숙,임경일 INSTITUTE OF TROPICAL MEDICINE YONSEI UNIVERSITY 1995 YONSEI REPORTS ON TROPICAL MEDICINE Vol.26 No.1

가시아메바 속(Acanthamoeba spp.)의 DNA 염기 구성 정보와 관계없이 임의의 10개의 염기로 구성된 프라이머를 사용하여 random amplified polymorphic DNA-polymerase chain reaction(RAPD-PCR)에 의해 게놈 상의 DNA를 무작위로 증폭하여 확인된 표지자로써 한국 분리주 및 외국 분리주와 기존의 알려진 4개 가시아메바 종간의 유전적 근연관계 분석을 통해서 4개 한국분리주의 분류상의 성상을 규명하였다. 본 연구에서 A. culbertsoni, A. hatchetti, A. triangularis, A. polyphaga와 한국 분리주인 YM-2, YM-3, YM-4, YM-5, 그리고 외국 분리주인 HOV의 게놈 DNA는 18종류의 프라이머에 의하여 다양한 양상의 증폭산물을 보였으며, 그 중 9개 프라이머는 한국 분리주간에도 특이성을 보이는 RAPD 표지자를 제공하였다. 총 18개의 프라이머에 대한 증폭산물을 대상으로 각 시료의 유사도를 조사한 결과, A. culbertsoni는 A. hatchetti, A. triangularis, A. polyphaga와 유사도가 각각 0.300, 0.308, 0.313이었고, A. hatchetti와 A. triangularis간의 유사도는 0.838이었다. 한국 분리주 YM-2, -3, -4간의 평균 유사도는 0.959이었고, YM-2, -3, -4와 A. hatchetti, A. triangularis간의 평균 유사도는 0.832이었다. 한국 분리주 YM-5는 YM-2, -3, -4 간의 비교에서 평균 0.237의 유사도를 보인 반면, A. culbertsoni와 유사도 0.857을 보여, 다른 한국 분리주보다 A. culbertsoni와 유전적으로 유사함을 알 수 있었다. UPGMA법에 의한 유전적 근연관계 분석 결과 phenogram 상에 두개의 분지군이 존재하는데, A. hatchetti, A. triangularis 및 3개 한국 분리주 (YM-2, -3, -4)가 하나의 분지군을, A. culbertsoni, A. polyphaga, HOV주, 및 YM-5가 다른 분지군을 형성하는 것으로 나타났다. 게놈 DNA 상의 변이에 근거하여 볼 때, YM-5 주는 유전적으로 A. culbertsoni와 거의 유사한 분리주이며 한국 분리주는 최소 2종 이상의 가시아메바로 분류할 수 있다고 사료된다. Genetic status of Acanthamoeba spp. were tested on the basis of random amplified polymorphic DNA(RAPD) marker analysis. Four previously established Acanthamoeba species. 4 Korean isolates of Acanthamoeba sp.. and one American isolate of Acanthamoeba sp. were analyzed by RAPD-PCR using an arbitrary decamer primers. Amplification products were fractionated by agarose gel electrophoresis and stained by ethidium bromide. Eighteen primers producted DNA amplification profiles revealing clear differences among 4 species. Nie of them also produced DNA amplification profiles which included some isolate-specific amplification products. On the basis of amplified fragments by 18 primers, the pairwise similarity indices between A. culbertsoni and other species (i.e., A. hatchetti, A. triangularis, A. polyphaga) were 0.300, 0.308, and 0.313, respectively. Similarity index between A. hatchetti and A. triangularis was 0.833. The mean similarity index among the 3 Korean isolates (YM-2,-3,-4) was 0.959 and 0.832 among them and 2 other species (A. hatchetti and A. triangularis). The mean similarity index among YM-5 and other Korean isolates (YM-2,-3,-4) was 0.237. However, the similarity index between YM-5 and A. culbertsoni was 0.857, which suggests that YM-5 is genetically more similar to A. culbertsoni than other Korean isolates. Phenogram reconstructed by UPGMA method revealed that there are two groups: one group consists of A. hatchetti, A. triangularis, and 3 Korean isolates (YM-2,-3,-4), and the other group consists of A. culbertsoni, A. polyphaga, HOV, and YM-5.

Present study suggest that why dropout in the activity of sport is the following results as the analysis of the human basic motives and previous research. 1. Results suggest that since 1980 the study of the dropout and motivation for participating in the sport has studied, however, it is necessary to more attend this area in future 2. The previous study has mainly focused on the withdrawal and participating on sport activity 3. Maintaing sport activity is highly related to the level of perceived competences. This reason is more likely to depend on the level of skill development and affiliation. 4. Most of research tends to study on the withdrawal on the athletes in the present and past rather than as leisure behaviors the peoples generally participated in sport. 5. Most of study relating to this area tends to focus on children, adolecent and male rather than female, elder and adults. 6. Result reveals that the difference of age, gender culture tends to affect significantly on the withdrawal of sport activity. 7. In Korea, the study of this area has been neglected and furthermore it only partly applied. 8. Furture study in this area, it is important to examine the level of casual and model for intergrating motive, it also necessary to focused on various aged to improve the quality of life.

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.

閔惠淑,全容赫,羅福瑛 고려대학교 의과대학 1982 고려대 의대 잡지 Vol.19 No.3

The effects of interaction between chlorambucil and crude ginseng extract (ginseng saponin) had teen investigated on liver cell of 90 experimental weanling albino rats from 22 healthy primiparous mother rats by means of histochemical detection as RNA, DNA and PAS positive materials 1. Severe regressive changes of the liver tissue, especially on the portal area, induced by intraperitoneal administration of single dose of chlorambucil rated 0.2㎎/0.1㏄ per 20㎎ of body weight had been protected or recovered from the degeneration by following administration of single dose of the crude ginseng extract rated 1.0㎎/0.1㏄ per 20㎎ of the body weight of young. 2. An abrupt declination of PAS positive material in hepatocyte due to use of chlorambucil was contrasted with a gradual inclination of it induced by use of crude ginseng extract, and the effect of the latter appears to be contributed for recovering the lower PAS reaction into that of the normal on the former hepatic cellular change. 3. A declination of stain property or RNA to Azure B was resulted from the use of chlorambucil, while that of DNA was not affected until 24 hours and later it was increased by 36 hours after the administration. 4. A slight decrease of the staining in both the DNA and RNA was recovered the property by 48 hours after the administration of crude ginseng extract. 5. On concomitant administration of both the chlorambucil and crude ginseng extract the staining property of the RNA to Azure B was shown a decrease in the initial stage, and was recovered in that of the normal immediately thereafter without influencing that for DNA.

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.
