Purpose: This study was performed to investigate the quantities of three neo-maternal exposures; visiting frequency, auditory contact and physical contact, and to examine the relationship between the quantities of each exposure and maternal attachment, maternal self-esteem and postpartum depression in 40 mothers of NICU babies during the first week in the NICU. Method: Each neo-maternal exposure was counted at every mother's visit to the newborn and maternal attachment, maternal self-esteem and postpartum depression were measured using the maternal attachment inventory, the maternal self-report inventory and Edinburgh Postpartum Depression Scale (EPDS) on the first and seventh day in the NICU. Result: The Mean of each neo-maternal exposure was 8.77(2.81) for the visiting frequency, 5.82(3.66) for the auditory contact and 5.60(2.89) for the physical contact during 7 days in the NICU. No significant changes were found in the scores of maternal attachment, maternal self-esteem and postpartum depression between the first and the seventh day in the NICU. The quantities of neo-maternal exposures were positively related to the scores of maternal attachment and maternal self-esteem but not related to postpartum depression. Conclusion: The results of the study suggest the lack of early neo-maternal exposure in cases of NICU hospitalization negate its beneficial effects on maternal psychological well-being in increasing maternal attachment and self-esteem. More efforts are neededfor the neo-maternal interaction and the reevaluation of NICU visitation hours in order to promote maternal-infant interaction.

Data containing 14,188 lactation and reproductive records of Korean Holstein cows at first parity distributed across 3,734 herd-year-season groups were analyzed to get genetic (co)variance estimates for milk yield, fat yield, calving ease, and days open. Milk and Fat yields were adjusted to 305 d. Heritabilities and genetic correlations were estimated in two different animal models on which were included direct genetic effects (Model 1) and direct+maternal genetic effects (Model 2) using REML algorithms. Milk and fat yields were affected by age at first calving as linear and quadratic. Heritability estimates of direct effects were 0.25 for milk yield, 0.17 for fat yield, 0.03 for calving ease and 0.03 for days open in Model 2. These estimates for maternal effects were 0.05, 0.08, 0.04 and less than 0.01 for each corresponding trait. Milk productions at first lactation were to show genetically favorable correlation with calving ease and days open for direct genetic effects (-0.24 - -0.11). Moreover, calving ease was correlated with days open of 0.30 for direct genetic effects. Correlations between direct and maternal effects for each trait were negatively correlated (-0.63 - -0.32). This study suggested that maternal additive genetic variance would be not ignorable for genetic evaluation of milk production as well as reproductive traits such as calving ease and days open at first parity. Furthermore, difficult calving would genetically influence the next conception.

Purpose: The purpose of this study was to determine the effects of music therapy on postpartum blues and maternal attachment of puerperal women. Methods: The research design was a nonequivalent control group non-synchronized design. The participants were puerperal women who agreed to participate in this study and through a convenience sampling, 60 puerperal women were recruited (30 in the experimental group, 30 in the control group). After measuring postpartum blues and maternal attachment, music therapy was provided to the experimental group over 40 min, once a day, and for 8 days. Then, postpartum blues and maternal attachment for the experimental and control group were measured again on the 8th day. The data were analyzed using the SPSS WIN 12.0 Program. Results: The first hypothesis that "the degree of postpartum blues for the experimental group who participated in music therapy would be lower than that of the control group" was accepted (t=4.350, p<.001). The second hypothesis that "the degree of maternal attachment of the experimental group who participated in music therapy would be higher than that of the control group" was accepted (t=4.828, p<.001). Conclusion: These findings indicate that music therapy has positive influences on decreasing postpartum blues and increasing maternal attachment of puerperal women.

The purpose of this study was to examine the moderating effects of mother-adolescent communication time on the relationship between maternal meta-emotion philosophy, adolescent psychological adjustment and depression. The participants for this study comprised 181 first and second grade high school students and their mothers, residing in Seoul. The results of the analyses indicated that, (a) maternal disapproving is negatively correlated to adolescents' positive world views, and that maternal laissez-faire is also negatively correlated to adolescents' emotional responsiveness. However, a positive correlation is revealed between maternal emotion-coaching and adolescents' positive self-esteem. (b) It is evident that adolescents' emotional responsiveness is influenced by maternal laissez-faire, and that adolescents' positive self-esteem is influenced by emotion-coaching. It also indicated that mother-adolescent communication time is influenced by dismissing as well as laissez-faire meta-emotion philosophy. (c) It revealed that mother-adolescent communication time, in part, has a meaningful moderating effect on the relationship between meta-emotion philosophy and adolescent depression. Therefore, the present study indicates that even if maternal disapproving, laissez-faire, or dismissing is practiced, adolescent depression levels decrease as mother-adolescent time lengthens.

Objectives : The aim of this study was to examine the effects of maternal sociodemographic characteristics, especially education and employment, and parenting stress on the child's self-concept. Attention was also paid to the mediating impact of parenting style on the relationship between the maternal variables and a child's self-concept. Methods : A questionnaire and three scales were completed by fifth graders and their mothers, and 270 sets of paired data were analyzed. Results : The results showed that mothers with higher education experienced less child-related parenting stress, were perceived to be more achievement-oriented and rational by their children, and also had children with more positive self-concept. The relationship between maternal education and child's self-concept was mediated by the rationality dimension of parenting style. Maternal employment was not related to parenting stress, parenting style and most aspects of the child's self-concept. Lastly, child-related parenting stress had a negative effect on the child's self-concept, and this effect was mediated by the warmth and rationality dimensions of parenting style. Conclusion : Parenting style had a mediating effect on the relationships between the child's self-concept and maternal education and child-related parenting stress.

Purpose: The purpose of this study was to investigate the effects of sensory stimulation conducted by primiparas on mother-infant interaction, maternal self-esteem and infant temperament. Method: A non-equivalent control group post-test study design was used. The data were collected from December 1, 2001 to March 30, 2003. The participants were 39 primiparas with normal birth weight infants. They were divided into two groups, 20 mothers in the intervention group and 19 in the control group. The mothers in the intervention group were given instruction on sensory stimulation by the researcher, and the mothers, in turn, used this technique on their infants twice a day during the first 2 months of life. Both groups were measured for maternal self-esteem and infant temperament using the maternal self-report inventory (MSRI) and What My Baby Is Like (WBL) and a film was made of the feeding situation when each infant was between 8 and 10 weeks of age. Results: Compared to the control group, the experimental group had significantly higher scores in mother-infant interaction, maternal self-concept and infant temperament. Conclusion: This suggests that sensory stimulation conducted by primiparas may improve the mother-infant interaction, maternal self-esteem and infant temperament.

This study examined the effects of maternal parenting, children's self-esteem and emotion regulation strategy on emotion regulation. Data were collected from 493 5th and 6th graders. The results were as follows: Firstly, maternal authoritarian and permissive parenting directly affected children's maladaptive emotion regulation, while maternal affectionate and permissive parenting directly affected children's adaptive emotion regulation. Secondly, children's selfesteem directly affected both their maladaptive and adaptive emotion regulation, while also acting as a mediator between maternal parenting and children's maladaptive and adaptive emotion regulation. Children's cognitive reappraiser strategy positively affected adaptive emotion regulation, but emotion suppressive strategy negatively affected adaptive emotion regulation. These emotion regulation strategies played a mediating role between maternal parenting or children's self-esteem and adaptive emotion regulation.

Iron deficiency anemia in pregnant women has been of great concern because of its negative effects on the outcomes of pregnancy. Much of evidence has shown that there are associations between pregnancy outcomes and maternal iron status. Maternal iron status might affect pregnancy outcomes through the iron status of the cord blood. In this study, we divided 91 subjects into two groups : the anemic and the normal groups. The groups were classified according to their hemoglobin(Hb) and hematocrit(Hct) values of the maternal blood in the third trimester of the pregnancies. We determined the parameters for the iron status of the cord blood and then analyzed the correlations between these parameters and the pregnancy outcomes. Mothers in the anemic group had a significantly higher parity number and a lower dietary score as well as a shorter duration of iron supplements consumed compared to those in the normal group. Maternal Hb values in the third trimester had positive correlations with the infant's head and chest circumferences, and the Hct values related positively to the infant's chest circumferences. On the other hand, Hb concentrations of the cord blood had positive correlations with the infant's height and head and chest circumferences. The Hct values of the cord blood had positive correlations with gestational periods and the cord lengths. These results suggest that the maternal iron status might influence fetal development through the iron status of the cord blood.

We investigated the effects of maternal parenting behavior and social supports on children's problem behaviors. The participants are 148 elementary school children and their teachers from one elementary school in Seoul. The data were analyzed by using descriptive statistics, correlation analysis, t-test, and multiple regression. The major findings are summarized as follows: (1) there were differences in maternal parenting behavior(warmth), teacher support, and internal problem behaviors according to children's gender; (2) mothers's parenting behavior(warmth) and teachers' support explained children's overt problem behaviors; and (3) mothers' parenting behaviors(supervision) and friends' support explained children's internal problem behaviors. In conclusion, there were differences between the subscale of maternal parenting behavior and social supports influencing overt problem behaviors and internal problem behaviors.
