The factors adopted in this experiment are volume fraction and the diameter and aspect ratio of fiber. The levels of factors are determined by existing studies. The effects of the diameter and mixing volume fraction and the aspect ratio for maximum strength, strain and tangent modulus are analyxed based on the linear multiple regression and we obtained regression equations as follows ; Maximum stress : σ_max=298.59820+95.78361φ-6.36043V_f+0.62067Ar Maximum strain at maximum stress : ε_max=0.021336+0.15746φ+0.05519V_f+0.00181Ar Tangent modulus : E=208209.80+87132.84φ-17286.69V_f-464.9181Ar where φ : diameter V_f : volume fraction Ar : Aspect Ratio

최재화,김호덕,심태섭,라봉진 중앙대학교 의과대학 의과학연구소 1985 中央醫大誌 Vol.10 No.1

For the study, forty-six normal adult ICR mice were sacrificed. Extraction of the hearts was performed under ether anesthesia after two consecutive subcutaneous injections of isoproterenol hydrochloride (1-/3', 4'-dihydroxyphenyl/-2-isopropylaminoethanol HCI). The administered doses of isoproterenol to each group of the mice were 20mg, 35mg, 50mg, 80mg, 100mg, 150mg, and 200mg per kilogram of body weight respectively, After extraction, the wet weight of each of the hearts was measured. Five μm-thick paraffin sections of the heart tissue fixed with alcohol-formalin were stained with hematoxylin and eosin for routine study, with van Gieson's method for collagen, and with von Kossa's method for histochemical study of calcium salt. Stained sections were examined under light microscope. The results were as follows: 1. All of the mice treated with isoproterenol showed myocardial necrosis-like lesions. These lesions spread from subendocardial area to entire myocardium in accordance with the increase of dose of isoproterenol and the prevalence rate of myocardial necrosis by isoproterenol administration was higher in the left ventricle than in the right ventricle. 2. The most typical histopathologic findings of myocardial necrosis were observed in the mice treated with 80mg of isoproterenol per kilogram of body weight. 3. The mice treated with 100mg, 150mg, and 200mg of isoproterenol per kilogram of body weight showed the death rate of 50%, 83%, and 100% respectively after the first administration. 4. All of the mice treated with isoproterenol showed calcium deposits in the myocardium. 5. The ratio of the wet weight of heart to the body weight increased in the mice treated with isoproterenol in comparison with the control mice.

This study investigates director, teacher, parent's recognition on the volunteer activities of parents in the kindergarten classrooms. The subjects of this study were 662 kindergarten directors, teachers, parents in Jeonbuk province, respectively 144, 212, 306. The data were collected using questionnaires and analyzed by the statistical methods of frequencies, percentages, a Chi-Square test with SPSS program. The major findings were as follows : 1) Directors, teachers, parents positively recognized the concept of volunteer that is parent's spontaneous, public benefit, development of self and nonsalaried activity. And it appeared need to volunteer activities in kindergarten because of effectiveness of early childhood education and understanding of the kindergarten. 2) They all recognized that volunteer's attitude needs the observance of role, most of all directors recognized knowledge of education principle, teachers and parents recognized fairly dealing with children. 3) They all recognized that pre-education needs to the understanding of early childhood education and children. 4) Most of the Directors, teachers, parents wanted the role of the simple assistant as a volunteer activities in kindergarten. 5) Most of the Directors, teachers, parents recognized that the assessment method needs to discussion among directors, teachers and parents and the assessment content needs to volunteer's attitude and capability of volunteer's role performance.

Paraquat 독성에 미치는 Dicumarol과 Allopurinol의 병합 투여 효과

송명화,정미숙,오순식,박재윤,차종희 조선대학교 1995 The Medical Journal of Chosun University Vol.20 No.1

Despite intensive investigation into paraquat toxicity, neither the final cytotoxic mechanism nor a clinically useful antidote has been discovered. The mechanism of paraquat cytotoxicity is also debatable, but it is generally accepted that a redox reaction occurs between reduced paraquat and molecular oxygen. The intracellular reduction of paraquat occurs by various enzymes, such as DT-diaphorase, xanthine oxidase and glutathione reductase. In present study, we investigated that the effects of allopurinol, a xanthine oxidase inhibitor, and dicumarol, a DT-diaphorase inhibitor, in paraquat-intoxicated rats. The survivals of paraquat-intoxicated rats were increased by allopurinol treatment compared to paraquat-treated control rats , but not effected by dicumarol treatment. The activity of xanthine oxidase in the liver of allopurinol-treated rats was decreased and DT-diaphorase activity in liver of dicumarol treated rats was also decreased compared to normal control rats. The contents of glutathione in liver of paraquat treated rats was decreased but in paraquat+allopurinol treated rats, the decrements of glutathione contents was reduced but in paraquat+dicumarol treated rats, liver glutathione level was not changed compared to paraquat-treated rats. These results suggest that paraquat toxicity maybe reduced by administration of allopurinol but dicumarol did not have such effects .

This study was to examine the mother's recognition to the preparatory education for the volunteer activities as a kindergarten class-assistance. The subjects were 186 mothers who participated in the preparatory education. Data collected using questionaires were analyzed by the statistical methods of frequencies, percentages, a Chi-Square test with SPSS program. Results showed as follows : 1) Most mothers were satisfied with the preparatory education. 2) They liked the lecture among teaching methods and they thought that 10 hours of 2 days and 20 hours of 3 days were proper to the length of education. 3) Their best subject was the play instruction for children and anybody didn't respond to like the subject of the evaluation among all subjects. 4) They recognized that reeducation was important and that it need to do one time within 6 months after participating the preparatory education. 5) They wanted to open this preparatory education to all mothers and to use various audio visual electric medias.

Effect of Coating mulberry leaves with ginseng solution on the weight of larva and cocoon, the cocoon layer ratio, the activities of GOT and GPT that are known to be important in amino acid metabolism. the activity of amylase. and the contents of cholesterol, triglyceride and sugar was investigated. The results are summerized as follows 1. Ginseng solution coated mulberry leaves were more effective in increasing the weight of larva and cocoon layer, and the cocoon Layer Ratio than non-coated leaves. 2. The activities of GOT and GPT in silkworms feeded with ginseng solution coated mulberry leaves decreased, and were inversely related with the concentration of ginseng. 3. The activity of amylase in silkworms feeded with ginseng solution coated mulberry leaves decreased, and was inversely related with the concentration of ginseng. 4. The contents of total cholesterol and triglyceride in silkworms feeded with ginseng solution coated mulberry leaves decreased. 5. The content of sugar in silkworms feeded with ginseng solution coated mulberry leaves decreased and appeared not to be inf1uenced by the concentration of ginseng.
