Cerebral and cerebellar atrophic changes on computerized tomography (CT) scans of 18 schizophrenics and 25 age-matched controls were reviewed. Sizes of variable portions of ventricles and several cisterns was measured and presence of abnormal widenings of several subarachnoid cisterns was investigated on CT scans. The prevalences of both cerebral and cerebellar atrophy were significantly higher(p=0.001, p=0.001) in the schizophrenics than the controls. However, all of the atrophic changes were questionable or mild except two cases in each supratentorial and infratentorial structures. The cerebral and cerebellar atrophic changes had statistically significant positive linear correlation. The mean symptom duration was significantly longer in the undifferentiated type than the paranoid type (p=0.007), in the cases with negative symptom than with positive symptom(p=0.03). Negative symptoms were more in the undifferentiated type. These findings were consistent with previous reports that correlate the cerebral and cerebellar atrophies with schizophrenia and these results suggest that the brain atrophy in schizophrenics is not an isolated event but a feature of diffuse brain atrophy.

幼弱白鼠 肝細胞內 DNA, RNA 및 PAS 陽性物質에 미치는 Chlorambucil과 Ginseng Saponin의 相互作用에 關한 組織化學的 硏究

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.

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).

The purpose of this study is to look into the effect of chemical structure of carrier for carrier dyeing of poly (ethylene terephthalate) (PET), rate of dyeing and dyeing transition temperature were investigated. In the series of carriers which have a phenyl ring, the dyeing transition temperatures were lowered, and diffusion coefficients were increased according as their molecular structures are similar to that of PET. Carriers which have a phenyl ring and carbonyl group showed an excellent carrier effect, and the order of carrier effect is Toluene <Ethylbenzene<Benzaldehyde<Acetophenone<Propiophenone. The carrier of which chemical structure is very similar to that of PET was the most effective carrier. This is due to the overlapping of p-porbitals of phenyl rings and carbonyl groups between carrier and PET.

To observe the developing process of human fetal eccrine sweat gland during the intrauterine life, an electron microscopic study was carried out based on 12 fetuses ranging from 20 to 42 weeks of gestation. These fetuses were the products of induced deliveries found to have not associated disease or congenital anomalies at the autopsy. Following observations were made. The various types of cell consisting coiled portion of eccrine sweat gland were recognized at the 20th weed of gestation and they were clear cells, undifferentiated dard cells, myoepithelial cells. clear cells were located in central central portion and dark or myoepithelial cells were in peripheral portion. While undifferentiated dark cells were randomly distributed in the straight portion of eccrine sweat gland. The differential points between clear cell and undifferentiated dark cell were its round nucleus and glycogen contents. Marked hydropic changes of clear cells were noted at the 30th week of gestation. Secretory granules were noted at the 31st week of gestation. Secretory cells in the coiled portion of eccrine sweat gland was not fully mature until the 42nd week of gestation. Clear cells showed clear cytoplasm, abundant free ribosomes and scanty organelles. Undifferentiated dark cells showed many mitochondria and few glycogen. Secretory granules were rarely seen. Myoepithelial cells showed a few mitochondria, glycogen and microfilaments. Among three portions of eccrine gland, duct lumen in the acral and coiled portion were formed through the intracellular canaliculus and in the straight portion were made through the intercellular canaliculus. The main basic morphological mechanism of the lumen formation were microvesicle formation and pinched off phenomenon.

The subjects of this research is 229 high school girls who major in dancing at high schools of arts, We used the new personality-testing method to fond how much and in what kind of way experiences in dancing at each major have influence on the change of personality. And also we took One Way ANOVA to find the factors that have effects on the change of personality and to verify the differences among the items such as majors, careers, time to begin dancing, rank to be born, religions, and ten items of characteristic personality based on how poor educational levels of the heads of their families are, etc. In this way, we came to a conclusion as follows. 1.The group of modern dancing has a higher anti-social tendency than that of Korean dancing and batlet by significance level(p〈.001) in comparison of each major. The group of middle school has a higher anti-social tendency than that of preschool children and primary school students by significance level(p〈.01) in comparison of time to begin dancing. We found there was self-regulation and anti-social nature by significance level(p〈.05) in comparison of religions. And we found there was leadership by significance level(p〈.05) in comparison of educational levels of the heads of families. 2.We found that, of six main factors, a career was the one which had much influence on the change of personality and there was significance level(p〈.01) among rest, thoughtfulness, and an anti-social tendency in comparison of careers. And also there was significance level(p〈.05) among achievement, activeness, a tendency of neurosis, and that of a mental disorder. Considering the conclusions above, We came to the conclusion that careers of high school girls which means participation in dancing or such experiences have much influence on the change of personality and that the factors related to religions somewhat have an effect on it. However, analysis is showed that such (actors as majors, time to begin dancing, rank to be born, and educational levels of the heads of families, etc. have few effect on it.

The purpose of this study was to show a coaching leadership style by investigating the relationship between discrepancy of leadership behavior and achievement motivaton. Questionnaires were given to 776 players(87 teams) of 9 sports belonging to middle and high schools in Pusan, and finally 695 questionnaires were analysed based on response set. The questionnaires were composed of three parts : 1) the LSS (Leadership Scale for Sports) by Chelladurai and Saleh(1980), 2) the scale of Competition-Related Motives in Sports by Willis(1982), 3) personal characteristics of players. Those materials were subjected to a series of statistical analyses. Item-to-total-correlation was used for item validity of the scales and Cronbach'α for internal consistency in items. Also, t-Test was available to identify the relationship between discrepancy of leadership behavor and achievement motivation. After those analyses of the data, the following conclusion could be drawn : 1. The most preferred leadership style is traininng and instruction, on the other hand, the least is autocratic behavior. So traininng and instruction is perceived best but autocratic behavior are not. 2. In democratic behavior the discrepancy is most excessive and in positive feedback it is quite the opposite. 3. In the relationship of the discrepancy of leadership style and achievement motivaton, there is significant difference with the discrepancy of traininng and instruction, autocratic behavior, and social support.
