The purpose of this study was to investigate kindergarten teachers' beliefs and practices for young children's literacy acquisition. Specifically, teachers' beliefs in terms of constructivism and its variance according to teacher characteristics, and teachers' use of literacy approaches and their variances according to young children's age and teacher characteristics were examined. Subjects were 280 teachers sampled from 39 kindergartens located in Pusan and Kyungnam Province. A Questionnaire was developed with the reference of Wortham(1998), Hopkin(1995) and Chung(1998) to collect data. Statistical methods used in this study were mean table, MANOVA, and Tukey post-hoc test. The conclusions derived from the discussion on the results of this study are as follows: Firstly, it was revealed that both the degree of teachers' beliefs on constructivism and the use of whole-language approach were comparatively high. Therefore kindergarten teachers seem to use whole-language approach based on their solid theoretical backgrounds. Secondly, kindergarten teachers are revealed to use whole-language approach more than skills approach to assist young children's literacy acquisition. This is a desirable tendency for balanced adoptions between the two approaches in the classrooms. Thirdly, the tendency for teachers to use the two literacy approachers does not vary according to the age of young children they teach. This can be a problematic classroom practice because the dominance of whole-language approach for younger children should shift progressively to include more skills approach as children reveals and develops emergent literacy. Therefore, this tendency should be reflected in teacher education programs. Fourthly, while teachers with higher status and education revealed higher beliefs on constructivism, and teachers with more teaching experience and higher education use more whole-language approach, teachers with less teaching experience use more skills approach. This should also be reflected in teacher education programs.

Pork was cooked using three kinds of instrument [electric grill (EG) for 5min., microwave oven (MW) for 6min. and reheated using a MW] and then extracted with 80% methanol. The Ames test was performed on the methanol extracts, employing the S. typhimurium tester strain, TA100. The methanol extract of cooked pork showed high mutagenicity ion the 5.0 mg/plate without the S9 mix, but a higher mutagenicity was induced with the S9 mix With increasing refrigeration (4℃) and freezing (-18℃) periods the extracts showed higher mutagenicities and TBA values, and the same results where shown with reheating. Correlations of the mutagenicity (-S9 mix) and rancidity of the pork cooked by EG, according to storage at and -18 ℃ and reheated by MW (1 min), were r=0.85, 0.86, 0.98 and 0.83, respectively. When the MW was used for reheating, the refrigeration storage (r=0.98) showed a higher correlation coefficient than for that stored frozen (r=0.83). From the structure of cooked pork, as observed by SEM, many vapor pathways were viewed in the pork reheated using themicrowave oven.

The present study was carried out to examine the effect of a carcinogen, aflatoxin B_1 on the pathogenesis of the bile duct changes in mice experimentally infected with Clonorchis sinensis metacercariae. A total of 75 male albino mice of the BALB/c strain was used, and divided into 3 group; group Ⅰ, treated with 1.0ppm aflatoxin B_1 in drinking water alone for 12 weeks; group Ⅱ, given 50 Clonorchis sinensis metacercariae alone and group Ⅲ, given 50 metacercariae at the beginning of the 12 week treatment with 1.0ppm aflatoxin B_1 in drinking water. Three mice were served as untreated-uninfected normal control. All mice were fed the standard protein diet which was synthesized and supplied by the Laborarory of Sam-Lip Food Co. Since the 4th week three mice from each group were removed and sacrigiced at 4 week interval up to the 32nd week. The hepatobiliary tissues were extracted and subsequently prepared for light microscopic examination. The tissue specimens were stained with hematoxylin and eosin. Mice in group Ⅰ showed no significant changes except the lower degrees of bile ductular proliferation and inflammatory cell infiltration at the portal regions at an earlier stage. In groups Ⅱ and Ⅲ there were remarkable together with extensive acute and chronic inflammatory cell infiltrations, cellular atypia and periductal fibrosis from earlier stages. However, in group Ⅲ the histopathological changes observed were more prominent than those in group Ⅱ throughout the observation. As the time elapsed, they showed gradual regression with some fluctuations in the degrees. No any evidences of malignant changes of epithelial cells were noted in group Ⅱ, but in group Ⅲ the first tumor was found at the 28th week and the second one was at the 32nd week, respectively. Histologically the tumors observed were well differentiated adenocarcinoma of the bile duct. It was appeared that the tumors were of peripheral origin with a tendency of multifocal growth. They also showed an infiltrative growth pattern, increased mucin droplets, increased nuclear-cytoplasmic ratio and nuclear hyperchromatism. No hepatocellular carcinoma was noticed throughout the observation. In conclusion, it was suggested that Clonorchis sinensis infection promotes carcinogenic action aflatoxin B_1, a carcinogenic agent.

The purpose of this study was to examine the relationship between obesity and dietary habit! life style habit of major field of Music. This study was to questionnaire major of Music in detail. The subjects were the college students of music in women university which was located in Seoul. Among them, the experimental group was major in vocal music and the control group was major in piano, wind and stringed instrument. The data collection was self-recording method and anthropometric index was height and weight. The rate of obese subject determined by Body Mass Index(BMI) above 23, was 18% in the experimental group and 4.2% in the control group and the body fat of experimental group was higher than the control group. Among the dietary habit questionnaires, eating speed, amount of food eating by alone and preference of sweeten food items of the experimental group had statistical significant difference from the control group. The practice time for major field of experimental group was significantly lower than the control group(82 min vs 150 min). Hours of sleep, number of meal time, preference of special food and duration of exercise items related to the musical performance were significantly differences between the experimental group and the control group. Therefore, dietary habit and life style related to musical performance may influenced to the development of obesity.

補助質問의 認知水準과 提示時期가 散文學習에 미치는 效果

鄭淑璟 東亞大學校 大學院 1986 大學院論文集 Vol.11 No.-

Adjunct questions are known as an effective adjunct aid for prose learning, having produced much research during these two decades. The purpose of persent study was to find out how the effect sizes vary according to cognitive levels and locations of questions. An expository material titled "On Psychology" was used for this experiment and two hundred and twenty six freshmen had read prose material and adhunct questions without having received right answers, and then had taken an achievement test immediately after reading session. Three hypotheses set on the basis of previous research results were as follows: Hypothesis Ⅰ : semantic prequestions will produce higher scores on general achievement, on semantic achievement, and on verbatim achievement than verbatim prequestions will. Hypothesis Ⅱ : Semantic prequestions will produce higher scores on general achievement, on semantic achievement, and on verbatim achievement than semantic postquestions will Hypothesis Ⅲ : Verbatim prequestions will produce higher scores on general achievement and verbatim achievement than verbatim prequestions will. According to the results of analysis of variance, the differences of scores by the levels and locations of questions were statistically significant. The t test results have further indicated the differential effects of these variables: 1) the scores obtained by the subjects with semantic prequestions were significantly higher on general achievement and verbatim achievement that the scores obtained by those either with verbatim prequestions or with semantic postquestions; 2) the scores obtained by the subjects with verbatim postquestions were significantly higher on general achievement and verbatim achievement than the scores obtained by the those with verbatim prequestions. The following conclusions were obtained from the results of present study. 1. High cognitive questions, say semantic questions, produce larger effects on the learning of prose material than lower cognitive questions do. 2. Semantic questions produce larger effects on the learning of prose material when they are located before than they are located after prose material. 3. Verbatim questions produce larger effects on the learning of prose material when they are located after than before prose material.

The purpose of this survey is to summerize the data acquired by our researchers in our research on actual state of 3 villages in kyung­ki procince in preparation of the further field work in which we investigated the subjects of 369 women using questionaire method and to suggest the following based on this analysis: 1. The rate of practising contraception amounts to 58.8% of the subjects and is relatively high, compared with other rural areas. 2. As for the kinds of contraceptive intrauterine divice (I.U.D) is used by the greatest number of the subjects, i.d., by 30% of the subjects and the next is in the order of oral pill and condom. 3. As for the place they get contraceptive appliance, 83.9% of the subjects are using the health center and the rate well explains their cooperation with the family planning programme of the government. 4. 38.8% of the subjects report the experience of abortion and this rate is remarkably high in the case of rural area. This result of high rate, not lower than the urban areas, is above all, due to their geographical nearness to the cities and regarded as a harmful factor to maternal health. It shows that we have to produce measures to prevent abortion by Integration of family planning programme and maternal­child health programme in the rural area. 5. 31.6% of the subjects have chosen the medical organization for their last birth and for that matter there is a considerable difference between urban and rural areas. Therefore, we have to make efforts in the direction of increasing deliveries at medical organization.
