The purpose of this study was to analyze toddlers' verbal and nonverbal interaction with their peers and caregivers according to the class size of child care centers in Seoul. The subjects of this study were 20, two-year-old(M=32.5 month) toddlers with peers and caregivers from child care centers in different class sizes, but with same caregiver-toddler ratio. Verbal and nonverbal interactions were videotaped during one hour indoor free play per child in the center. According to the class size, the results were as follows : 1) Toddlers in the small class played more cooperatively with peers, and uttered more regulative or directive words than those in the large class. 2) Toddlers in the large class were more aggressive than those in the small class. 3) Caregivers in small class expressed more empathetic behaviors to a toddler than those in large class.

The aim of the present study was to compare child care center directors and teachers' recognition of criteria for class placements, specifically for children who were born in January or February, children's ability, and for mixed-age classes. The subjects were 398 center directors and 383 teachers in Seoul, Gyeonggi-do, Jeolla-do, Gangwon-do, Choongcheong-do and Gyeongsang-do. Data were analyzed by SPSS 12.0 and the t-test and Chi-square test were used. The results were as follows: (1) Most child care center directors and teachers believed that children born in January or February should share a classroom with classmates of the same age. (2) Most child care center directors and teachers believed that regardless of a child's ability, it was desirable for the child to be in a class with classmates of the same age. (3) Child care center directors thought that the current criteria for teacher-child ratios within a mixed-age classroom were acceptable but should be lowered if the child care center was not experiencing financial problems. Meanwhile, most of the teachers thought that lower teacher-child ratios within a mixed-age classroom was desirable.

Mothers of 58 20-month-olds in Seoul, the Republic of Korea, completed vocabulary checklists for their children. When vocabulary level was taken into account, children's vocabularies contained relatively greater proportions of nouns than other word classes, and more verbs than adjectives or closed-class words. Correlations among word classes showed that each word class was consistently positively correlated with every other class. Girls' vocabularies showed evidence of being larger than boys. Large individual differences in the sizes of children's vocabularies were found. Factors that influence vocabulary size and can account for gender and individual differences are discussed. Noun prevalence in the vocabularies of children learning to speak Korean, and the merits of several theories that may account for this word-class prevalence pattern, are evaluated.

The purpose of this study was to examine mother's child rearing practices by mothers of their first-born child as a function of child's sex, temperament, and social class and of mother's marital satisfaction. The subjects were 158 mothers of 3-year-old first-born children in Seoul. Block (1984)'s CRPR, Buss and Plomin (1975)'s EAS, and Roach et al.'s MSS (1981) were used to measure maternal child rearing practices, children's temperament, and mother's marital satisfaction, respectively. The statistical methods for data analysis included t-test, ANOVA, Duncan's multiple range test, multiple regression. The major findings showed there were no sex of child differences in child rearing practices. Social class differences were found in "encouragement of independence", "enjoyment of child" and "openness to experience" in maternal child rearing practices. There were differences in maternal child rearing practices by child's temperament and mother's marital satisfaction. In a multiple regression analysis, it was found that the most significant predictor of maternal child rearing practices was mother's marital satisfaction.

Objective: This study aimed to provide policy implications by studying the class size of early childhood education institutes. Methods: By looking through researches, the educational influence of class size was examined. By using the latest statistical data, class size standard and status were compared. After class size perception in the field was considered and the main results of advanced researches were summarized and analyzed, the actual condition of class size was diagnosed. Furthermore, the national research trend was analyzed. Results: First, class size was an influencing factor on young children and teachers and its importance was reconfirmed. Second, as for standard in relation to class size in Korea, the maximum class size and teacher-child ratio were not presented together. In respect of overseas standards, infancy has similar standards, but early childhood has a little higher ratio. In the educational fields, there was growing awareness that class size should be modified. Third, there were not enough domestic researches on class size and they tended to be biased in terms of the method, targets, and contents. Conclusion/Implications: It is suggested that it is necessary to establish a class size policy for future early childhood education institutes, to implement a system, and to perform follow-up studies.

The purpose of the present research was to investigate developmental trends in children's class-inclusion performance and to examine the influence of task characteristics(provision or deprivation of quantitative information and perceptual information) on a class-inclusion task. The subjects of this study were 96 children, 12boys and 12girls at each age level. 5, 6. 7 and 8 years of age. The experimental materials consisted of 12 stimulus boards which were constructed on the basis of picture cards used by Judd and Mervis(1979) and Lane and Hodkin(1985). The class-inclusion tasks were individually administered by the researcher. The data were analyzed by the statistical methods of t-test, one-way ANOVA and Duncan multiple range test. The results showed that (1) There were significant age differences in children's class-inclusion performance. That is, children's performance scores on the class-inclusion task increased with age.: (2) There were significant task characteristics differences in children's class-inclusion performance. That is, children performed better on the deprivation of quantitative information task than on the provision of quantitative information task.

This study was designed to investigate the variation of mandibular pattern and cranial base and their association in the craniofacial malocclusion. The material was the 165 cephalometric radiographs taken from craniofacial malocclusion. The sample was devided into two groups by age child group aged from 10 to 13 years and adult group aged over 18 years, and each group was devided into 3 types of malocclusion; class I, Class II div. 1 and Class III malocclusion. Child group consist of 35 samples and adult group consist of 20 samples in each malocclusion type. Various angular and linear measurements on the cephalometric radiographs were recorded and statistically analyzed. The results of the study were as follows; 1. The cranial base angle was largest in Class II div. 1 malocclusion and smallest in Class III malocclusion 2. The anterior cranial base length was largest in Class II div. 1 malocclusion but posterior cranial base length did not show statistical difference. 3. The mandibular body length of Class III malocclusion was larger than those of Class I and Class II div. 1 malocclusion in the adult group but did not shown difference in the child group. The ramus height of Class III malocclusion was larger than those of Class I and Class II div. 1 malocclusion in the child and adult group, but there were no difference between Class I and Class II div. 1 malocclusion. 4. The mandibular position was showed low correlation with the cranial base angele.
