This study examined the effects on preschooler's social competence of preschooler's emotional regulation strategies and maternal attitude toward child's emotional expressiveness. Subjects were 57 3-to 5-year-old preschoolers, their mothers and 3 teachers in their classes. Data were adapted from the Social Intelligence part of Project Spectrum and analyzed by Pearson Correlation Coefficient and Stepwise Multiple Regression Analysis. Findings were that : (1) preschoolers' positive emotion regulation strategies significantly explained their social competence. (2) Older children showed higher social competence than younger children; the effect of children's age on social competence was more influential than emotional strategies or maternal attitudes. In conclusion, preschooler's emotion regulation strategies are an important factor as their social competence develops with age.

Purpose: The Purpose of this study was to investigate relationships between maternal fetal attachment and state anxiety for pregnant women in preterm labor. Methods: The subjects consisted of 56 pregnant women in preterm labor on C hospital. The data were analyzed using SPSS computer program that includes descriptive statistics, mean, standard deviation, t-test, ANOVA, Scheffe? test and Pearson correlation coefficient. Results: Age distribution was 30~39 years of age. Mean score of maternal fetal attachment was 91.50. The group whose planned pregnancy was highest showed higher maternal fetal attachment. The primigravida group showed high maternal fetal attachment. Most frequently practiced attachment item was: "I'm really looking forward to seeing what the baby looks like". The next was was: "I enjoy watching my tummy jiggle as the baby kicks inside". There was no difference in degree of anxiety by general and obstetrical characteristics. There was statistically significant of negative correlation between maternal fetal attachment and state anxiety for pregnant women with preterm labor. Conclusion: Findings provide useful information for further studies in reducing anxiety and intervention programs relating to pregnancy and preterm labor. To increase maternal fetal attachment of pregnant women with preterm labor, it is necessary to standardize prenatal education program.

Purpose: This study aimed to analyze the impact of advanced maternal and paternal age on perinatal outcome in Korea. Methods: We conducted a retrospective study involving 1,622 Korean women who delivered at M Woman Hospital from January to December 2010 and their spouses were included. We obtained obstetrics database which included demographic characteristics, medical and obstetrics history, course of the current pregnancy and advised perinatal outcome. Multivariable logistic regression was used to adjust for potential confounding variables. Results: Women giving birth age 35 or older were statistically significant in paternal age, gravidity, spontaneous abortion experience, method of conception, method of delivery, and multiple gestation compared to women aged <34 years. After adjusting for the confounding effects of maternal characteristics, women aged 35 or older were at increased risk for cesarean section delivery (adjusted OR 1.6, 95% CI 1.22-2.13) and preterm birth (adjusted OR 2.2, 95% CI 1.03-4.63). Conclusion: In this population of Korean women, advance maternal and paternal age is independently associated with specific adverse perinatal outcome, especially preterm birth and cesarean section delivery.

Purpose: Increased maternal age is a major risk factor for chromosomal abnormalities. The maternal age-specific risk of fetal trisomy was theoretically calculated. We investigated the actual frequency of fetal trisomy between 16 and 24 gestational weeks in pregnant women over the age of 34 at delivery. Materials and Methods: We retrospectively, over a four-year period, reviewed the medical records of women with singleton pregnancies that started their antenatal care before the 10th week of pregnancy. Pregnant women aged 34 to 45 years at the time of delivery were enrolled and divided into groups of one-year intervals. We investigated the frequency of Down syndrome and all trisomies as a function of the maternal age and compared with the theoretical maternal-age-specific risk. Results: Of the 5,858 pregnant women enrolled in the study, the rate of trisomy 21 was 0.29% (17 cases). The observed frequencies of trisomy 21 in women with maternal ages of 35 years and 40 years were 1:1,116 and 1:141, respectively. The rate of all trisomies was 0.39% (23 cases). The observed frequencies of all trisomies in women with maternal ages of 35 years and 40 years were 1:372 and 1:56, respectively. Conclusion: The frequencies of Down syndrome and all trisomies were proportional to the maternal age. However, the observed frequencies of Down syndrome and all trisomies between the 16 and 24 gestational weeks were lower than the theoretical rates.

Objectives: The aim of this study was to evaluate the impact of shifts in maternal age and parity on the increasing trends in the low birth weight (LBW) and very low birth weight (VLBW) rates from 2005 to 2015 in South Korea. Methods: Data from 4 993 041 live births registered with Statistics Korea during the period between 2005 and 2015 were analyzed. Applying a modified standardization method, we partitioned the total increment in the LBW and VLBW rates into (1) the increase in the LBW and VLBW rates due to changes in the maternal age and parity distribution (AP-dis) and (2) the increase due to changes in the age-specific and parity-specific rates (AP-spe) of LBW and VLBW for singleton and multiple births, respectively. Results: During the study period, the total increment in the LBW and VLBW rates was 1.43%p and 0.25%p, respectively. Among singleton births, changes in the AP-dis accounted for 79% (0.34%p) and 50% (0.06%p) of the total increment in the LBW and VLBW rates, respectively. Meanwhile, among multiple births, changes in the AP-dis did not contribute to the increase in the LBW and VLBW rates, with 100% of the increase in the LBW (1.00%p) and VLBW (0.13%p) rates being attributed to changes in the AP-spe. Conclusions: This study demonstrated that shifts in maternal age and parity were prominent contributors to the increase in the LBW and VLBW rates among singleton births between 2005 and 2015 in South Korea.

The relations of mothers' attitudes regarding maternal employment to mothers' psychological well-being, mothers' parenting sensitivity and children's social competence were examined for mothers who worked full-time (extensively) from age 6 months of their children on, mothers who were not employed, and mothers who worked part-time or inconsistently during their children's early years. Longitudinal observations of 1,034 mothers and children in the NICHD Study of Early Child Care from age one month to first grade were analyzed using structural equation models. As predicted, mothers and children benefited when maternal attitudes were consistent with mother's actual employment status. Among extensively employed mothers, those with positive attitudes about employment had better psychological well-being; among mothers who were not employed, those who believed that maternal employment would have negative consequences for children's development reported better psychological well-being. The findings suggested that whether the mother's status of employment is congruent with their beliefs, not whether the mother is working or not, predicted the mother's well-being and their child's social development.

The purpose of this study was to examine the effects of a child's demographic variables and maternal perceptions of the conditions of happiness on their happiness for mothers. The participants of this study comprised 916 mothers of young children, school-aged children, and adolescents. The results revealed that a child's age and the numbers of children influenced maternal happiness when mothers' demographic variables were controlled. In addition, mothers who exhibited high degree of need in terms of the conditions of happiness regarding existence, relatedness, and growth were more likely to be happy than mothers who exhibited low degree of needs. Finally, the expectations regarding growth, which refers to the pursuit of self-accomplishment and meaning, was the most important predictor of maternal happiness. These findings have implications for parent education programs for mothers of young children, school-aged children, and adolescents.

Although Korean population has been growing steadily during the past four decades, the nation is rapidly becoming an aging society because of its declining birth rate combined with an increasing life expectancy. In addition, Korea has one of the lowest fertility rates in the world due to fewer married couples, advanced maternal age, and falling birth rate. The prevalence of low birth weight infants and multiple births has been increased compared with the decrease in the birth rate. Moreover, the number of congenital anomalies is expected to increase due to the advanced maternal age. In addition, the number of interracial children is expected to increase due to the rise in the number of international marriages. However, the maternal education level is high, single-mother birth rate is low, and the gender imbalance has lessened. The number of overweight babies has been decreased, as more pregnant women are receiving adequate prenatal care. Compared to the Asian average birth weight, the average birth weight is the highest in Asia. Moreover, the rate of low birth weight infants is low, and infant mortality is similarly low across Asia. Using birth data from Statistics Korea and studies of birth outcomes in Korea and abroad, this study aimed to assess the changes in maternal and infant characteristics associated with birth outcomes during the past four decades and identify necessary information infrastructures to study countermeasures the decrease in birth rate and increase in low birth weight infants in Korea.

Purposes: The purposes of this descriptive survey study were to describe levels of Maternal-Fetal Interaction Belief and Maternal-Fetal Interaction, and to define their correlation. Method: Data were collected from 273 pregnant women who visited one public health center and OB/GY clinic in Gangneung city. The instrument used for this study was a self-report questionnaire that included the Maternal-Fetal Interaction Belief scale(MFIBS) and maternal-fetal interaction. Results: The mean scores for maternal-fetal interaction belief and maternal-fetal interaction were $107.41{\pm}15.67$ and $31.75{\pm}5.92$ respectively. For maternal-fetal interaction belief, there were significant differences according to education, religion, income, feeding plan, marriage satisfaction, family support, and husband's love. For maternal-fetal interaction, there were significant differences according to mother's age, period of pregnancy, marriage satisfaction, family support, husband's love. There was a correlation between maternal-fetal interaction belief and maternal-fetal interaction. Conclusion: Maternal-fetal interaction belief is related to increase in maternal-fetal interaction and fetal development. It is essential to develop a maternal-fetal interaction program that includes maternal-fetal interaction belief.

Objective: The aim of this study was to evaluate the influence of maternal age on fertilization, embryo quality, and clinical pregnancy in patients undergoing intracytoplasmic sperm injection (ICSI) using testicular sperm from partners with azoospermia. Methods: A total of 416 ICSI cycles using testicular spermatozoa from partners with obstructive azoospermia (OA, n = 301) and non-obstructive azoospermia (NOA, n = 115) were analyzed. Female patients were divided into the following age groups: 27 to 31 years, 32 to 36 years, and 37 to 41 years. The rates of fertilization, high-quality embryos, clinical pregnancy, and delivery were compared across maternal age groups between the OA and NOA groups. Results: The rates of fertilization and high-quality embryos were not significantly different among the maternal age groups. Similarly, the clinical pregnancy and delivery rates were not significantly different. The fertilization rate was significantly higher in the OA group than in the NOA group (p< 0.05). Age-group analysis revealed that the fertilization and high-quality embryo rates were significantly different between the OA and NOA groups in patients aged 27 to 31 years old, but not for the other age groups. Although the clinical pregnancy and delivery rates differed between the OA and NOA groups across all age groups, significant differences were not observed. Conclusion: In couples using testicular sperm from male partners with azoospermia, pregnancy and delivery outcomes were not affected by maternal age. However, women older than 37 years using testicular sperm from partners with azoospermia should be advised of the increased incidence of pregnancy failure.
