In this study of 79 3- and 4-year-old children, behavioral inhibition was assessed by their preschool teachers; mother-child attachment was assessed by the researchers in home visits; and mothers reported on their parenting and their child's emotionality at 6-12 months of age. Findings were that insecure attachment was related to high child's distress reactions to limitations (negative emotionality) in early infancy and to strong maternal rejection/hostility. Higher maternal sensitivity to child's inhibition was related to more secure attachment. Girls were more highly inhibited than boys. Smiling and laughter (positive emotionality) in early infancy was negatively related to child's inhibited behavior. Maternal sensitivity to child inhibition was positively related to child's inhibited behavior. Findings are consistent with Engfer's (1993) theory of gender differences in developmental paths into behavioral inhibition.

Purpose: The purpose of this study is to identify the association between maternal feeding practices and excessive weight gain in infants. Methods: This study adopted a cross-sectional design and included 240 pairs of mothers and their infants (129 boys and 111 girls) in public healthcare centers in the Daejeon area in South Korea. Via multivariate analyses, the association between maternal feeding practices and excessive weight gain in infants was identified. Results: Among 240 infants in this study, 39 (16.3%) infants gained excessive weight during 12 months after birth. Using multivariate logistic regression with adjustment for covariates, more than 7 months of exclusive breastfeeding was associated with a reduced likelihood of excessive weight gain in infants during the 12 months after birth (adjusted odds ratio: 0.39, 95% confidence interval: 0.02~0.81, p=.029). Conclusion: Based on these results, nurses in communities and clinics should educate mothers on the importance of longer durations of exclusive breast feeding and develop strategies for encouraging such behavior. Furthermore, support for exclusive breast feeding should be provided in various settings.

The relationship between children's behavior problems and perceptions of their parents' childrearing behaviors was studied in 359 fourth graders. Children reported on perceptions of their parents' childrearing behaviors with the Childrearing Behavior Questionnaire (Park, 1995) and on their own behavior with the Korean Youth Self-Report (K-YSR; Oh, Lee, Hong, & Hah, 1997). Data were analyzed with descriptive statistics, t-test, and hierarchical multiple regression. Results showed that girls viewed their fathers and mothers as more warm/accepting and their fathers as less rejecting/restricting than boys. Boys had more externalizing (aggressive/delinquent) behavior problems than girls. Children's internalizing behavior problems were positively related to their perceptions of paternal and maternal rejection/restriction and permissive/non-interfering. The relationship was differed as a function of child's sex. Children's externalizing behavior problems were positively related to their perceptions of paternal and maternal rejection/restriction and paternal permissive/non-interfering. The relationship was differed as a function of child's sex.

The purpose of this study is to investigate the effect on maternal perception of her infant and the infant's behavior development through maternal education designed to provide information of the capabilities and the individual characteristics of her infant. The subjects were 48 pairs of normal infants and mothers at three different hospitals, 24 pairs for the intervention group and 24 pairs of the control group. The survey was conducted from July 30 to October 6, 2001. The results of this study were as the following. A maternal perception of her infant was significantly different between the two groups, more positive in the intervention group than in the control group. The information and understanding of behavioral characteristics of the infant are an important factor influencing maternal perception for her infant and general development of the infant. On the basis of these results, the educational intervention method of this study may be worth utilizing in nursing practice. The practitioners of hospitals have to establish a system that it offers an education of understanding the infant's behavioral characteristics during the hospitalization after delivery.

This study was conducted to identify the characteristics of paternal and maternal grandmothers' social support, and to investigate the relationship between paternal and maternal grandmothers' social support and their school-aged grandchildren's psychological adaptation. The participants of this study were 215 students in the 5th and 6th grades and their mothers residing in Daegu. Collected data were analyzed using t-test, paired t-test, ANOV A, Scheffe's test, and hierarchical multiple regression. Findings of this study are as follows: 1. School-aged children perceived that their maternal grandmothers rendered more emotional and informational support than their paternal grandmothers. 2. Paternal grandmother's social support as perceived by the grandchild varied significantly with the frequency of face-to-face contact, the frequency of phone contact, and the friendship between the paternal grandmother and the mother. Maternal grandmother's social support as perceived by the grandchild, on the other hand, varied significantly by the level of grandmother's education, the frequency of face-to-face contact, and the frequency of phone contact. 3. Perceived paternal and maternal grandmothers' social support had indirect impacts on grandchildren's depression, which was mediated by their mothers' parenting.

The purpose of this study was to investigate the effect of mother's smartphone dependency and maternal guilty feelings on early childhood emotion regulation. The subjects were 326 mothers of 2 to 5 year olds. Mothers' smartphone dependency was assessed by the Korea Agency for Digital Opportunity & Promotion(2006), guilty feelings by the Maternal Guilt Scale(Sung 2011), and early childhood emotion regulation assessed by the ERC(Park 2012). The results of the study were as follows. First, mother's dependency on smartphones was highly related with early childhood emotion regulation. Maternal guilty feelingswere weakly related with child's emotion regulation. Relationship between mother's dependency on smartphones and maternal guilty feelingswasmoderate. Second, mother's positive expectations towardssmartphones and maternal guilty feelings from negative parenting behavior explained early childhood emotion regulation as much as 69%.

Purpose: The main purpose of this study was to establish a nursing intervention data base to improve maternal attachment. Method: The first group of mothers( control group), experienced their first physical contact with their infants after being discharged from the hospital. The second group (experimental group) practiced early initial mother-infant postpartum contact known as the most sensitive period for founding maternal-infancy attachment. The subjects of this study gave birth to normal infants at M hospital from Aug.25 to Sept.30, 2004. During the same time, data was collected through direct observation, with instruments designed by Cropley et al., to assess the behaviors of normal attachment. The statistical methods for data analysis were percentage, mean, standard deviation and t-test with an SPSS program. Result: The group practicing initial mother-infant contact, showed a higher degree of physical and functional bonding than the group experiencing the first contact after discharge from the :10spital (control group)(p<.0l). The group practicing initial mother-infant contact, showed higher degrees of bonding attachment assessments than the group experiencing their first initial contact after their discharge from the hospital(p<.01). Conclusion: The group practicing early mother-infant contact, showed more maternal-infant interaction than the group experiencing their initial contact after their discharge from the hospital. These results show that maternal attachment behavior increases according with an early initial mother-infant contact.

Matemal behaviors of Korean mothers of one-year-old infants (26 boys and 21 girls) were observed at home. Mothers were from middle to upper-middle class families in Seoul. Trained observers visited the infant's home for 3 to 4 hours and observed infant-mother interactions in natural situation. After the home visit, observers sorted the Maternal Behavior Q-set into 9 piles, from most characteristics to least characteristics of the mothers. In general, Korean mothers were quite sensitive and responsive in their interactions with one-year-old babies. Mothers interpreted baby's cues correctly, noticed when baby was distressed, and slowed pace down to wait for baby's response. Maternal behaviors were somewhat different according to whether they interacted with boys or girls. Mothers of boys were observed to be less sensitive in their interactions than mothers of girls. Mothers of boys were more unaware of or insensitive to baby's signs of distress, their responses were more delayed, and provided baby to constant and unphased barrage of stimulation thus made baby overwhelmed. In contrast, mothers of girls enjoyed face-to-face interactions, slowed pace down, and their interactions revolved around baby's tempo and state.

Exposure to early stressful adverse life events such as maternal and social separation plays an essential role in the development of the nervous system. Adolescent Sprague-Dawley rats that were separated on postnatal day 14 from their dam and litters (maternal social separation, MSS) showed hyperactivity and anxiolytic behavior in the open field test, elevated plus-maze test, and forced-swim test. Biologically, the number of astrocytes was significantly increased in the prefrontal cortex of MSS adolescent rats. The hyperactive and anxiolytic phenotype and biological alteration produced by this MSS protocol may provide a useful animal model for investigating the neurobiology of psychiatric disorders of childhood-onset diseases, such as attention deficient hyperactive disorder.

Ketamine has long been used as an anesthetic agent. However, ketamine use is associated with numerous side effects, including flashbacks, amnesia, delirium, and aggressive or violent behavior. Ketamine has also been abused as a cocktail with ecstasy, cocaine, and methamphetamine. Several studies have investigated therapeutic applications of ketamine, demonstrating its antidepressant and anxiolytic effects in both humans and rodents. We recently reported that neonatal maternal separation causes enhanced anxiety- and aggressive-like behaviors in adolescent. In the present study, we evaluated how acute and chronic ketamine administration affected the behavioral consequences of neonatal maternal separation in adolescent mice. Litters were separated from dams for 4 hours per day for 19 days beginning after weaning. Upon reaching adolescence (post-natal day 35-49), mice were acutely (single injection) or chronically (7 daily injections) treated with a sub-anesthetic dose (15 mg/kg) of ketamine. At least 1 h after administration of ketamine, mice were subjected to open-field, elevated-plus maze, and resident-intruder tests. We found that acute ketamine treatment reduced locomotor activity. In contrast, chronic ketamine treatment decreased anxiety, as evidenced by increased time spent on open arms in the elevated-plus maze, and remarkably reduced the number and duration of attacks. In conclusion, the present study suggests that ketamine has potential for the treatment of anxiety and aggressive or violent behaviors.
