The purpose of this study is to analyze the relative importance of three factor -socioeconomic development, public health development, egalitarian nature of socioeconomic development- affecting mortality declines. Infant mortality rate and life expectancy at birth are used as the mortality index, that is the dependent variables, while GNP is used as the indicator of socioeconomic development, primary school enrollment ratio of female as the indicator of egalitarian nature of socioeconomic development, population per hospital bed as the indicator of public health. The data of these variables are collected two time-periods -before 1970 and during 1970-1980- over 50 countries. The explanatory data analysis is used as the statistical technique. We can find whether the relationship between dependent variable and independent variables are linear or nonlinear, and which case is the influential case in our model. The main results of this study are followings. First, the association between infant mortality rates and four indices are not linear. The most important factor explaining the variation of infant mortality is GNP, while primary enrollment of female is the second and GINI is the third important factor. However, population per hospital bed does not have a significant effect on the infant mortality rates in this study. Second, life expectancy at birth is log-linearly related to GNP. Unlike infant mortality rates, the most important factor explaining the variation of life expectance at birth is women's education and the next important factor GNP, and then the third one GINI. But, still population per hospital bed is not significantly related to the variation of life expectance in this study.

The purpose of the study was to assess the knowledge of infant development of child care teachers, undergraduate students majoring in child development at universities, and the students at child care training centers. A questionnaire was distributed to 126 in-service and 187 pre-service child care teachers. Data were analyzed by t-test, F-test, Correlation. The results showed that the mean scores of subjects on the Knowledge of Infant Development Inventory (KIDI) were relatively low. Among the 3 groups of subjects, child care teachers had the lowest scores on the KIDI. There were individual differences in the knowledge of infant development by school year, the length of work experience, marital status, age of child, attendance at in-service training events, and kind of license.

This longitudinal study investigated developmental changes in temperament and examined social adjustment problems by early temperamental characteristics and developmental patterns of temperamental change during infancy. Subjects were 153 six-month-old infants and their mothers. Infant temperament and toddler's problem behavior were measured by the Infant Behavior Questionnaire-Revised (Garstein & Rothbart, 2003) and the Toddler Behavior Checklist (Larzelere et al., 1989), respectively. Results showed that distress to limitations, high pleasure, perceptual sensitivity, and approach increased with age, while activity level, cuddliness, and vocal reactivity decreased. Infants with high scores in activity level, fear, sadness, and approach at 6 months showed more problem behaviors at 18 months. Infants showing abrupt developmental change of high pleasure and perceptual sensitivity developed more negative behavior.

The purpose of this study was to explore the relationship among the mother's knowledge of infant development, mother's parenting stress, maternal parenting behavior and infant development. Participations in this study included 2078 infants(1056 boys, 1022 girls) and their mother. The major results of this study were as follows: First mother's knowledge of infants showed positive effects on maternal parenting behaviors, and mother's parenting stress showed negative effects on maternal parenting behaviors. Second, maternal parenting behaviors and mother's knowledge of infants showed positive effect on infant development. But maternal parenting stress didn't show direct effect on infant development. In conclusion, maternal parenting behaviors partially mediated between mother's knowledge of infants and infant development, and fully mediated between mother's parenting stress and infant development.

This study investigated differences in toddlers' language development depending on their teachers' types of interaction during reading of picture books. A pilot study identified teachers' types of interaction as instructional, non-immediate, and passive. Fifteen teachers recruited from 10 child-care centers located in Seoul and their 90 2-year-old toddlers participated in this study. Teachers read two picture books to a small group of toddlers each week for eight weeks. Data on the toddlers' receptive and expressive language, vocabulary, reading behavior, and book handling were collected and compared by their teachers' interaction type before and after teachers' 8-week reading of picture books. Results showed that teachers using the non-immediate interaction type had the most positive effects on toddlers' language development.

This study investigated relationships between engagement in joint attention and the early language development in infancy. Subjects were 12 infants and their mothers. At 20 and 25 months of age, each child's spontaneous natural speech during interaction with his/her caregiver was videotaped for about 30 minutes. The EJA(Episodes of joint attention) focus between mother and child were identified and coded by Tomasello and Todd's(1983) and Bakeman and Adamson's(1984) including person engagement, object engagement, looking engagement, passive joint attention, coordinated joint attention. Results showed that a significant difference in infant's language development between within and outside EJA at 20 and 25 months of age; that is, during periods of EJA children talked more inside than outside EJA.

The main purpose of this study was to investigate the paths from the cumulative risk factors to infant's development at 24 months of age via the mediation of maternal parenting behaviors. The data consisted of 3 year's worth of data harvested from 1802 families participating in the Panel Study on Korean Children (PSKC). The results revealed that cumulative family risk factors tended to stay in the family in relatively stable ways. Early risk factors significantly predicted later risk factors. Cumulative risk factors were negatively associated with the parenting styles of mothers, which in turn, significantly predicted the development of the infants concerned. Statistical tests supported the notion that mothers' parenting behavior is the mediator of the relation between family risk factors and infant's developmental outcomes.

This study aims to examine the relationship between mothers' attachment levels, types of verbal control, and infants' language development. The selected participants comprised 224 infants, aged 24-35 months and their mothers (224) at 25 long day care centers located Goyang-si, Gimpo-si in Gyeonggi-do, Incheon and Seoul. The major findings of this study were as follows. First, there were significant differences in mothers' attachment levels, types of verbal control, and infants' language development depending on the mothers' employment status. Secondly, to assess the relative influences of two variables which were significantly associated with infants' language development, the sociodemographic variables of mothers and infants, including infants' age and mothers' employment status, were controlled in order to conduct hierarchical regression analysis. The results revealed that imperative-oriented verbal controls, person-oriented verbal controls, and contact seeking all influenced infants' overall language development.
