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 analyzed relations among maternal parenting behavior, infant development and parenting stress focusing on the moderating effect of parenting stress. Subjects were 30 infants and their mothers. After videotaping the mother-infant free play session, maternal parenting was analyzed by the Parent Child Interaction Play Assessment(Mash & Terdal, 1981); mothers' parenting stress was measured by questionnaire. Infant development was measured individually by the Korean Bayley Scale of Infant Development (K-BSID-II). Correlation analyses revealed that infant cognitive development correlated significantly with maternal parenting behavior (attention) but the relation between them was moderated by maternal parenting stress; only the low parenting stress group showed a positive relationship between maternal parenting behavior and infant development.

This study investigated characteristics and types of ideal maternal behaviors in three different cultures : Korea, the United States, and France. The 18 experts from each of the 3 cultures who participated in this study had knowledge and experience related to infant development and parenting. Based on the principles of Q-methodology, the experts sorted 40 Q-items representing maternal behavior related to infancy. After rating each item on a scale from "least desirable" to "most desirable" maternal behaviors, the experts described their reasons for the classification. Results identified some clear similarities and differences among cultures. pooled responses yielded 3 types of ideal maternal behaviors: perfective, child centered, and realistic perspective.

The purpose of this study was to examine early emotionality and mothering and fathering antecedents of inhibition of children at age 3 years in a sample of 100 children(51 boys; 49 girls). In order to assess child's behavioral inhibition and mothering, the behaviors of each child-mother dyad was videotaped in a structured lab situation. Data on Fathering behavior were gathered through questionnaires. 2X2ANOVA, Hierachical Regression Analyses and Fisher's Z test were conducted for the statistical analyses. The main results were as follows; 1) Only small portion of the variance in subsequent inhibition could be explained by early emotionality(i.e.negative, positive, and the interaction of both emotionality). 2) High negativity coupled with low positivity in infancy predicted high inhibition especially for girls. 3) In general, sensitive mothering and appropriateness of mothers' response were related to child's low inhibition, while parental intrusiveness and negative affect increased child's inhibition. 4) Mothering appeared more influential in the case of children who showed low positivity during infancy. The importance of distinguishing positive and negative emotionality in infancy and studying parental behavior to predict child's inhibition were discussed.

Two sub-standies were conducted to analyze attachment related variables in infants and characteristics of maternal behavior. The first study investigated the relationships among attachment related variables in infants. The sample consisted of 58 pairs of 11- to 13- months-old infants and their mothers. A significant relationship was found among attachment security, infant temperament and maternal sensitivity. There were differences between security scores of the easy and difficult infants. Securely attached infants were rated as easier temperamentally than insecurely attached infants. The second study analyze maternal behavior characteristics. Subjects were this 30 mothers whose children were between the ages of 2 months and 24 months. The results identified four types of maternal behaviors. This study suggests different method of assessing subjective attributes of individuals by introducing Q-methods to the field of child development.

Parenting knowledge is regarded as an important variable influencing parenting style. This study investigated the parenting knowledge of mothers with infants and analyzed how this knowledge influenced their parenting style. The mothers’ parenting efficacy was included in the analysis as a mediator between parenting knowledge and parenting style. Three hundred and seventy-five mothers with infants completed questionnaires regarding parenting knowledge, parenting efficacy, and parenting style. The results showed that the mothers reported different scores in subcategories of parenting knowledge, in which the highest scores were in knowledge about rearing behavior and the lowest were in the developmental process. Second, there were differences in parenting knowledge scores according to the age, employment status, and educational level of subjects. Third, subjects with the more accurate parenting knowledge reported more positive parenting efficacy and parenting style. Lastly, parenting efficacy completely mediated between parenting knowledge and parenting style.

The purpose of this study was to investigate the changes in infant-mother interactions and to measure infant-mother interaction, mutuality, and reciprocity at the 2nd and 6th postnatal monthperiods. Infant-mother interaction was assessed in the mornings, afternoons, and evenings in the 2nd and 6th postnatal months, by filming unstructured free play in the home and analyzing 28 of these infant-mother film recordingsusing two trained observers. This study can be summarized in five points. First, the separate frequency distribution of each category in MIIBR's maternal behavior was as follows: the frequencies of vocalization category, the kinesthetic exercise & physical contact category, the physical caregiving category, and theuse of play tool category. These all showed changes in the 6th postnatal month compared to the 2nd postnatal month. Second, the separate frequency distribution of each category in MIIBR's infant behavior was as follows: the frequencies of physical behavior category, the vocalization category, and the play behavior category. These also all showed changes in the 6th postnatal month compared to the 2nd postnatal month. Third, the mutuality and reciprocity of mother interaction decreased in the 2nd postnatal month compared to the 6th postnatal month. Fourth, mutuality and reciprocity in the infant interaction increased in 2nd postnatal month compared to the 6th postnatal month. Fifth, mutuality and reciprocity in the infant-mother interaction increased in 2nd postnatal month compared to the 6th postnatal month. In conclusion, it is evident that infant-mother interactions change over time. This study bears particular significance in setting a foundation for the theoretical basis of the interaction between infant and mother by observation.

This study was designed to investigate the effects of a sensory stimulation program on the growth (weight, height, head circumference, and chest circumference), behavioral development, behavioral states, and the heart rate of the infants. A total of 23 infants of 2 weeks old were divided into sensory stimualtion group (11 infants) and control group (12 infants). The infants of sensory stimulation group had received sensory stimulation for 6 weeks. Sensory stimulation program was composed of tactile and kinesthetic stimulation. We assessed growth, behavioral state and heart rate every week and behavioral development every 2 weeks. The results were as follows: 1. Body weight in sensory stimulation group, from two weeks after the sensory stimulation program, was significantly increased more than control group, but there was no significant difference in height, head circumference, and chest circumference between the two groups. 2. Behavioral developmental score of sensory stimulation group was significantly higher than that of control group from two weeks after the sensory stimulation program. Developmental states of sensory stimulation group showed more 'high average developmental state' than the control group from 4 weeks after sensory stimulation program. 3. Behavioral states of sensory stimulation group after the sensory stimulation program, the 'sleeping state' was significantly increased more than control group. The 'awakening state' and the state of fuss or crying were significantly less than those of the control group. 4. The heart rate of the sensory stimulation group after the sensory stimulation was significantly lower than the control group. These results indicate that the sensory stimulation program decreases heart rate and improves the sleeping state to be effective on promoting the growth and development of the infants. In view of these experiments, we suggest sensory stimulation program might be considered as a nursing intervention for growth and development of the infants not only in clinical settings but also at homes and in the communities.

The purpose of this study is to identify the characteristics and influencing factors of the attachment-oriented caretaking behaviors among the mothers with infants. The total number of 204 mothers participated in this survey as subjects. They all were breast-feeding mothers who had their infants joining in the semi-final round of a healthy breast-feeding infant contest. The data were collected from July 14, 1999 to May 19, 2000. And the data were analyzed by SPSSWIN 10.0 version. The result of this study was as follows ; 1. The mean ages of the subjects were 29.5 and 95.6 percents of them were no-job housewives. 57.8% of them were normal delivery. And the mean months of the infants were 6.2 and the male infants were 57.4%. The first born babies were 62.3%. 2. The mothers are affirmative enough with their attachment-oriented caretaking behaviors (the total mean was $3.58{\pm}.631$). In general, the mothers showed very attachment-oriented caretaking behaviors, but the points that indicated "recording the development characteristics of the infant and discussing them with husband" were very low(score $2.79{\pm}.982$). 3. There are Significant differences in caretaking behaviors of the mothers according to their ages(F=3.497, p=.017), the degree of morning sickness(F=2.633, p=.050) and the birth order of their infants(F=4.854, p=.003). The older mothers and mothers who experienced the less morning sickness showed the higher scores of the attachment-oriented behaviors. The mothers who experienced the more deliveries showed the higher scores of the attachment-oriented behaviors. Accordingly, the above result suggests that the systematic and practical nursing intervention to encourage the attachment-oriented behaviors is essential to the younger, primipara mother.

This study explored the longitudinal developmental paths of preschooler's external problem behaviors from infancy. Subjects consisted of 205 preschoolers (106 boys, 99 girls aged 4) and their mothers recruited for the 2009 in-depth Panel Study on Korean Children. Data were analyzed by descriptive statistics, correlations, and structural equation modeling using SPSS 18.0 (SPSS Co., Chicago, IL, USA), Amos 18.0 (SPSS Co., Chicago, IL, USA). The results were as follows: Maternal depression at preschooler's age 0 had a direct effect on maternal social parenting style at preschooler's age 0. Maternal social parenting style at preschooler's age 0 had a direct effect on preschooler's effortful control at age 1. Preschooler's effortful control at age 1 had a direct effect on preschooler's external problem behaviors at age 4. Marital conflict at preschooler's age 0 did not have a direct effect on preschooler's effortful control at age 1. The direct effects of maternal depression at preschooler's age 0 on preschooler's effortful control at age 1, and on preschooler's external problem behaviors at age 4 were not significant. In addition, direct effect of maternal social parenting style at preschooler's age 0 on preschooler's external problem behaviors at age 4 was not significant. This study showed that maternal psychological characteristics, marital conflict, maternal social parenting style and preschooler's effortful control in infancy should be considered simultaneously to explain the effect on preschooler's external problem behaviors.
