The objectives of this study were to analyze the longitudinal mediation effects of maternal parenting stress and psychosocial development of infant on the influence of paternal involvement during infancy to children's peer interactions. For these objectives, latent growth modeling was used and adapted to the data taken from the Panel Study on Korean Children(PSKC), Wave I (0-year olds) to Wave III (2-year olds) and Wave V(4-year olds) to Wave VII(6-year olds). During a total of six years, 1,018 parent responded. The major results of this study were as follows. First, maternal parenting stress(initial status) had a significant mediating effect on the influence of paternal involvement(initial status) to children's play interaction(initial status). Second, maternal parenting stress(initial status/change rate) had a longitudinal mediating eff ect on the influence of paternal involvements(initial status/change rate) to children's play disruption-disconnection interactions(initial status/change rate). Third, psychosocial development of infants(initial status/change rate) had a longitudinal mediating effect on the influence of paternal involvement(initial status/change rate) to children's play interactions(initial status/change rate). Fourth, psychosocial development of infant(initial status) had a significant mediating effect on the influence of paternal involvement(initial status) to children's play disruption-disconnection interactions(initial status). The implications of the findings of the current study and suggestions for future research were also discussed.

Purpose: This study was aimed to evaluate the effects of a maternal education program based on the temperament theory on the temperamental goodness-of-fit between mother and child. Method: The research method was a nonequivalent, control group, non-synchronized design and the experimental period was from May 10, 2004 to July 24, 2004. The subjects were mothers who had children 3-4 years old who registered in eight kindergartens or infant schools in M city. Among the total 94 subjects, 47 were allocated as an experimental group and 47 were a control group. Using the SPSS/WIN 10.0 program, the data was analyzed by a Chi-square test, and t-test. Result: 1. After treatment with a maternal education program based on the temperament theory, the experimental group significantly decreased in scores for perceived children's behavior problems in comparison to the control group(t=-4.01, p<.001). 2. After treatment with a maternal education program based on the temperament theory, the experimental group did not significantly decrease in scores for parenting stress in comparison to the control group(t=-.85, p=.40). 3. After treatment with a maternal education program based on the temperament theory, the experimental group did not significantly decrease in scores for rejective parenting behaviors in comparison to the control group(t=-1.32, p=.19). Conclusion: A maternal education program based on the temperament theory is a useful intervention to decrease perceived children's behavior problems.

This study investigated the effect of maternal interactive styles, parenting stress, home environment stimulation and social support on poverty in early childhood. Participants consisted of 145 mothers and their children living in Seoul and Kyounggi Province. Data included videotaped observations of parent-child play and standardized measures of social support, parenting stress, home environment, and child development. Results of the t-test indicated significant differences among father's age and education, mother's age and education, and income over the variable of poverty. Regression analyses indicated that home environment stimulation was the strongest predictor of variance in children's development. Results from the regression analyse were supportive of the hypothesis that home environment moderates the impact of poverty on children's development.

This study was conducted to compare the emotional state between the mothers with low-birth-weights and mothers with normal infants, and to analyze the effects of home visiting for the low-birth-weights in one city. Data were collected from 51 mothers with low-birth-weights and 90 mothers with normal infants to compare emotional state, and from 26 mothers with low-birth weights to evaluate the effect of home visiting care. Summaries of results were as follows; 1. In mothers with low-birth-weights, social support form others was significantly lower than those of mothers with normal infants. Although the differences were not significant, mothers with low-birth-weights have more stress and child rearing burden, and less maternal self-esteem than those of mothers with normal infants. 2. Mothers with low-birth-weights, the more burden, postpartum depression, and the less husbands' support they felt. When they had lower maternal self-esteem and lower husbands' support, child rearing burden was higher. Also there was significant negative correlation between maternal self-esteem and postpartum depression. 3. In mothers with low-birth-weights, the score of post-intervention stress, care-giving burden, and postpartum depression were somewhat decreased, and maternal self-esteem was increased than pre-intervention data, although they were not statistically significant. 4. Mothers' satisfaction on the home-visiting care was considered to be high. In summary, mothers with low-birth-weights had lower social support even though they experienced more stress than mothers with normal infants. Therefore, public health nurse in community should pay more attention to them.

This paper was composed with fatigue test of the cruciform specimens, as load carrying and non-load carrying type. It also has performed computational analyses for geometric condition of the fillet welding bead. As test results, the effect of stress ratio in the specimen was insignificant. Stress ranges were varied with R=0.1~0.2. The fatigue cracks that were found in the load carrying type specimens and most specimens welded with contact were developed at the end of welds. The fatigue strength of specimen that have fractured in maternal plate was found about ${\Delta}\sigma_c$=63.5MPa. It's about 24% less than that of the non-load carrying type specimens having about ${\Delta}\sigma_c$=83.8MPa. A category of the Fatigue design specifications which provide for cruciform details was defined grade C as a stress of the maternal member. And then, the fatigue strength to be transformed into the maternal stress was found about 78.27 MPa, it tends to be less than that of allowable fatigue strength.

Dexamethasone, a synthetic glucocorticoid (GC), is clinically administered to woman at risk for premature labor to induce fetal lung maturation. However, exposure to repeated or excess GCs leads to intrauterine growth restriction (IUGR) and subsequently increases risk of psychiatric and cardio-metabolic diseases in later life through fetal programming mechanisms. GCs are key mediators of stress responses, therefore, maternal nutrient restriction or psychological stress during pregnancy also causes negative impacts on birth and neurodevelopment outcome of fetuses, and other congenital defects, such as craniofacial and skeletal abnormalities. In this study, to examine the effect of prenatal stress on fetal skeletal development, dexamethasone (1 mg/kg [DEX1] or 10 mg/kg [DEX10] maternal body weight per day) was administered intraperitoneally at gestational day 7.5~9.5 and the skeletons were prepared from embryos at day 18.5. Seven out of eighteen (39%) embryos treated with DEX10 showed axial skeletal abnormalities in either the T13 or L1 vertebrae. In addition, examination of the sternum revealed that xiphoid process, the protrusive triangular part of the lower end of the sternum, was bent more outward or inward in DEX group embryos. In conclusion, our findings suggest a possible link to the understanding of the effect of uterine environment to the fetal skeletal features.

The purpose of this study was to examine the effects of parenting efficacy, parenting stress on elementary school children's self-efficacy and daily stress. The subjects were 355 children selected from 4 elementary schools and their mothers. Data was collected using the parenting efficacy index, parenting stress index, children's self-efficacy inventory and children's daily stress inventory. Data was statistically analyzed using the t-test, one way ANOVA(Duncan test), correlation analysis and multiple regression analysis. The study showed that there were some significant differences in children's self-efficacy according to the child's grade, gender, scholastic achievement, mother education, father education, and income. There were some significant differences in children's daily stress according to the child's grade, gender, and scholastic achievement. Correlation analysis indicated that the maternal parenting efficacy and children's self-efficacy, especially self-confidence had a significant positive correlation, and indicated a negative correlation with children's daily stress. Correlation analysis indicated that maternal parenting stress and children's self-efficacy had a significant negative correlation, and indicated a positive correlation with children's daily stress. It was also found that scholastic achievement, educational distress of the mother, father education were significant predictors of the children's self-efficacy, and healthy parenting ability, father education, stress of a difficult child, scholastic achievement, gender were all significant predictors of the children's daily stress.

The purpose of this study was to analyze the intake of antioxidant vitamins and plasma TRAP concentrations of 60 maternal-infant pairs (30 in normal term delivery group, NT; 30 in preform group, PT) We also investigated the relationship between plasma TRAP levels of maternal-umbilical cord blood and pregnancy outcomes. Mean energy intakes of NT and PT pregnant women were 93.2% and 85.4% and their protein intakes were 113.3% and 110.9% of the recommended dietary allowance (RDA), respectively. The vitamin A intakes of NT and W pregnant women were 559.7 RE and 497.8 RE, which were less than RDA. While the vitamin E and C intakes of both NT and PT pregnant women were more than RDA. The maternal plasma TRAP level of PT was 1.41 mmol/l and that of was 1.50 mmol/l, which was significantly higher than TRAP level of PT (p < 0.05) . The umblical cord plasma TRAP levels of NT and PT were 1.44 mmol/l and 1.23 mmol/l, which indicates the significant difference between those two groups (p < 0.001) . In case of comparing the TRAP level of maternal and umbilical cord blood, there was no significant difference in NT pregnant women, however, in PT group maternal the TRAP level significant higher than that of umbilical cord (p < 0.001). The length of gestation and plasma TRAP level of maternal and umbilical cord showed a positive correlation. However, other parameters of pregnancy outcomes such as birth weight, weight gain, and Apgar score were not affected by the plasma TRAP levels. Based on these results, preform infants could have a risk of oxidative stress because of low plasma TRAP level.

Objectives : The purpose of this study was to investigate the relationships between mother's and child's temper and parenting stress. Methods : One hundred twenty healthy mothers (above 20 yrs old) who has a school-aged child (7-11 yrs old) participated after informed consent. The temperament of the children was analyzed by the Junior Temperament and Character Inventory 7-11 (JTCI 7-11) by their mothers. The temperament of the mothers was analyzed by the Temperament and Character Inventory-Revised Short (TCI-RS) and the mother's parenting stress was analyzed by the Korean Parenting Stress Index (K-PSI). The relationships between mothers' and child's temperament and parenting stress were assessed using the Pearson correlation coefficient and multiple regression test. Results : There were significant correlations between maternal temperaments and child's temperaments and maternal parenting stress. There was a positive correlation between mother's harm avoidance characteristic, child's novelty seeking degree and parenting stress. On the other hand, there was a negative correlation between child's persistence and parenting stress. In addition, interactions between child and mother temperament dimensions predicted higher levels of parenting stress. Parenting stress was higher in the group of high mother's harm avoidance with child's high novelty seeking and high mother's harm avoidance with low child's persistence. Conclusions : These results are showing that there are significant relationships between mother and child temperament and parenting stress in mothers with school-aged children.

The purpose of this research was to evaluate the effectiveness of the Counseling-Utilized Parent Education for Mothers (CUPEM). CUPEM was developed based on Developmentally Appropriate Practices, Solution-Focused Therapy, Satir's Experiential Family Therapy, and Cognitive-Behavioral Therapy. The subjects were 51 mothers of 4 and 5 year old children and randomly assigned either to the intervention group (n=26) or the comparison group (n=25). Mothers in the intervention group had 10-2 hour intervention sessions while those in the comparison group received the intervention after this study was completed. Both groups received pre-and post-test evaluation, and a follow-up test. The data were analyzed by t-test and paired t-test. The results showed that participanting mothers' parenting stress was lessened while sense of parenting competence and positive maternal behaviors during mother-child interaction were increased significantly. Second, these mothers' self-confidence and maternal attitude toward childrearing were improved. Third, this effect lasted for at least one month after the termination of this program.
