The purpose of this study was to investigate the effect of child care type on infant's developmental outcomes assessed by K-ASQ, focusing on the child-centric role of nurture policy. For this, this study categorized child care type into types including home nurturing, child care center, and subtypes of each category. The findings of multiple regression analysis using the first-third wave data of Panel Study of Korean Children(PSKC) are as follows. First, the child care center experience had rather positive effect on the development of all abilities in the infants comparing to home nurturing. Second, the time of attending child care center was differently related to the development of motor, communication, and personal-social skill in infanthood. Finally, the accreditation of child care showed a difference only in terms of social development of infants. In conclusion, even if the experience of using child care center has positive impact on infant's developmental level, it is still in need of improving service quality such as reinforcing accreditation system.

The purpose of this study is to identify factors that affect the language development of infants. For the analysis, data of three years from the first year (2008) to the third year (2010) of the 'Panel Study on Korean Children (PSKC)' were constructed and panel analysis was conducted. The subjects were 2,150 infants who participated in the questionnaire, and the language development of the infants was measured using the communication scores of the K-ASQ test provided by the Korean children's panel. In addition, the factors influencing the language development of infants derived from previous studies were introduced into the model. As a result of the analysis, it is shown that the fixed effect model with fixed individual error of the panel is suitable through the Hausman test. The higher the cognitive development level of the infant, the more positive parenting behavior of the infant, respectively. The conclusions and suggestions about the characteristics of the parents and the parents affecting language development were introduced.

This study investigated relationships among infant development, teacher's sensitivity, home literacy environment, and infant-teacher interaction in the child care setting. Verbal and behavioral interactions between 30 2-year-old infant-teacher pairs were video-recorded during free play activities; teachers' sensitivity was observed by trained observers; infant development was assessed by teachers; data on the early home literacy environment were gathered through maternal self-reported questionnaires. Data were analyzed by descriptive statistics, t-tests, and correlation analyses. Results indicated that boys showed more naming; girls showed more physical contact with teachers. Infants high in overall developmental level showed more behavioral interaction with teachers. Teacher's sensitivity correlated positively with behavioral imitating and negatively with questioning and nodding. Verbal interaction in the home correlated positively with nodding.

This study aims to observe the impact of mothers' child-rearing stress on the development of 3-month-old, breastfeeding and non-breastfeeding infants. For this purpose, a survey based on the K-ASQ scale was conducted on a sample of 533 3-month-old infants and their mothers in the Seoul and Kyeong-gi area. The results of the study are as follows. First, breastfeeding mothers felt less child-rearing stress than their non-breastfeeding counterparts, especially in parent-role stress. Second, breastfeeding infants exhibited a better personal sociality than non-breastfeeding infants. Third, it was found that mothers' child-rearing stress had an impact on all aspects of infant development in breastfeeding infants, and especially in the development of communicational skills, having an impact of 12.4%. However, in non-breastfeeding infants, mothers' child-rearing stress had an impact only on communication and personal sociality development and exhibited a nonsignificant impact on other aspects. Lastly, it was found that mothers' parent-role stress, out of all aspects of child-rearing stress, was the main factor of negative impact on infant development in both breastfeeding and non-breastfeeding infants. Based on the results of this study, I have suggested family-level and society-level support measures to reduce mothers' parent-role stress and promote breastfeeding.

This study examined the effect of infant teacher's sensitivity, efficacy and interaction on the social and emotional development of infants. The participants of this study were 169 infants and their teachers in daycare centers located in Seoul and Gyeonggi-do. The instruments were collected through teachers' responses. Data were analyzed through the variance analysis using PASW 18.0 to verify the infant teachers' susceptibility, efficacy, and infant-teacher interaction based on infant teachers' background variables; to find out the relationship between the variables, Pearson correlation analysis was performed, and to find out the relative influence of variables on the infants' social and emotional development, stepwise multiple regression analysis was performed. Results were as follows. Firstly, Among the background variables of the teachers, their career as infant teachers displayed differences in the infants' social and emotional development, and the susceptibility, efficacy, and infant-teacher interactions displayed partial differences based on the teaching career, career as infant teachers, age, daycare center type, and the academic background of the teachers. Secondly, there were positive relationships between infant teacher's sensitivity, efficacy and interaction and infants' social and emotional development. Thirdly, infant teachers' sensitivity, efficacy and infant-teacher interaction had an influence on infants' social and emotional development at the same time. Especially, sensitivity and interaction were powerful and influential variables and their explained variance was 53%. These results suggested that teachers' efforts must be made to interact positively with infants and to increase their sensitivity level to respond to infants in order to increase infants' social and emotional development.

The purpose of this study is to investigate the level of knowledge that mothers have on child development. To do so, a Knowledge of Child Development Inventory(KCDI) developed by Larsen &Juhasz(1986) was carried on to 156 mothers with an infant range from birth to age 24 months. The findings of the study were twofold: First, 70% of the questions on average were answered correctly by the participants. In other words, mothers generally demonstrated a high level of knowledge on child development. With regard to knowledge of child development, their knowledge on physical development of children was relatively low in comparison with that of cognitive and emotional development. In addition, mothers with a girl were more aware of child development especially in relation to child's emotional development. Also, mothers who delivered a heavier baby at birth possessed a higher level of knowledge concerning child's physical development. Second, other external factors, such as the level of family income and mother's education, played a significant role in affecting the level of knowledge on child development. Unsurprisingly, mothers with a higher income and education level demonstrated a higher level of knowledge on child's cognitive development. The findings of the study implicates that mothers seldom demonstrate a proper level of knowledge on child development. Hence, this study suggests that a practical, functional training services and resources for current and future mothers must be ensued.

Recent research indicates that the n-3 fatty acid , docosahexaenoic acid(22 : 6n 3, DHA) plays an essential role in infant brain development . DHA is highly concentrated in brain and retinal tissues and accumulates during late fetal and early neonatal life. Diets deficient in DHA are associated with reduced levels of DHA in brain and retinal tissues. The purpose of this study is to investigate the long term effects of DHA supplementation on the growth and mental development of full-term infants. THirty four healty infants were recruited from those who were delivered at Kyung Hee Medical Center. The experimental groups were the breast milk+DHA(-) group who were fed human milk for 20 weeks after birth and thereafter were fed placebo formula for 28 weeks, the breast milk+DHA(+) group who were fed human milk for 20 weeks after birth and thereafter were fed DHA supplemented formula for 28 weeks, DHA(-) group who were fed placebo formula for 48 weeks, and DHA(+) group who were fed DHA supplemented formula for 48 weeks. The daily average intake of DHA for the breast milk+DHA(-) , breast milk+DHA(+), DHA(-) and DHA(+) groups were 39.1mg, 89.9mg, 17.7mg, and 160.224mg, respectively. The results showed that measurements of infant weight, length, head, and chest circumferncewere all in normal range and they were not influenced by the DHA supplements in their diets. There was a significant correlation between dietary DHA intake and erythrocyte DHA level. The results of flash visual evoke potential (VEP) test were not correlated with eerythrocyte DHA and dietary DHA levels at 48 weeks of age. No differences were found in Bayley mental and Psychomotor Development lndex scores among the four experimental groups at 48 weeks of age. Unlike the short-term effects there was no long-term effect of relatively small amounts of dietary DHA supplements on the scores for flash VEP and Bayley test, even thour호 there was an elevated DHA supplements on the scores for flash VEP and Bayley test, even through there was an elevated DHA content in the infants erythrocytes.

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.

This study looked into changes in the parenting stress and the depression of mothers whose children at the age of three or younger have been suffering from developmental risk, and discussed how the parenting stress would constantly influence the depression. In order to achieve the research goal, the study used the data from the Panel Study of Korean Children. According to the findings of the study, first of all, the parenting stress increased significantly for the next four years after the childbirth. The study also understood that there are personal differences among the mothers in relation to how much the stress gets worse overtime. Second, more severe the parenting stress during the year of the childbirth, the greater the depression during the same year, and this parenting stress's being intensified even more greatly for the four years right after the childbirth turned out to have a significant effect on how much the depression develops. What this study has found out so far confirms that the depression of the mothers will get reduced when the mothers of the children with the developmental risks before the age of three try to efficiently deal with their parenting stress.

The purpose of this study is to understand in detail the development of infants in the 18-24-month period when language develops the most, and to prepare new standards for developmental evaluation that can promote appropriate intervention design at an early time. We divided sub-items such as screening tests and standardized test tools to know the language development ability indicators of infants aged 18-24 months were divided into syntax/phonology, meaning, and speech, and each question was classified and a checklist was made on a five-point scale to conduct a survey on parents with infants aged 18-24 months. Low sensitivity to screening of infants with language delays in nationally implemented infant health checkups, and domestic test tools are standardized for at least six to as many as 10 years, which is always possible in questionnaires related to acceptance and expression, with many reports from parents or teachers.The proportion of "wow" and "started to do" was more than 50-60%. Based on the results of this study, it is hoped that new standards for developmental evaluation will be developed to promote the design of appropriate interventions in detail at a short time.
