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.

The purpose of this study was to contribute to maternal nursing in early postpartum stage and to neonatal nursing. Data were collected through self-report questionnaires which were constructed to include parental role stress scale, state-trait anxiety scale, and perception of the newborn scale. The subjects consisted of 100 mothers in the early postpartum stage at three hospitals in the Kyoung-In area, from November 8 to December 26, 1997. The data were analyzed by an SPSS program. The results are as follows ; 1. The mean of parental role stress of mothers in the early postpartum stage was 10.70$\pm$2.63. The means of state anxiety and trait anxiety of mothers were 36.29$\pm$8.45 and 38.53$\pm$8.36. The mean of perception of the newborn was 2.65$\pm$5.05, and 59% of mothers rated their newborn as better than the average newborn. 2. The level of parental role stress correlated to the level of state anxiety and trait anxiety. The level of state anxiety and trait anxiety were also related. The level of perception of the newborn was related to the level of state anxiety and trait anxiety. 3. Mothers who did not want the pregnancy, whose newborns were girls, and who already had one child had higher state anxiety than those who did not. Mothers who already had one child, and whose newborn had no specific signs had higher trait anxiety than those who did not. Mothers who professed a religions had a higher perception of the newborn than those who did not. The above findings indicate that the levels of parental role stress, state anxiety, trait anxiety and perception of the newborn of mothers in early postpartum stage were correlated. Therefore nursing intervention for reducing stress and anxiety, and improving perception of the newborn should be provided for mothers in early postpartum stage.

The purpose of this study was to find pathways among factors that distinguish the mothers' intention to have a second child. As for factors affecting the childbirth intention of mothers, this study aimed to explore pathways from fathers' participation in childrearing to intention of second childbirth as mediating variables, maternal parenting stress and marital satisfaction. This study used the third wave data of the Panel Study of Korean Children (PSKC) that is a national-representative birth-cohort study. Among the 1,802 participants of the PSKC, 717 mothers who have a husband/partner and only one child have responded a decided intention of second childbirth. SPSS 19.0 and Amos 19.0 were used to implement exploratory analyses of predictors and test path models. Results showed that the hypothetical model assuming a path from paternal involvement in childrearing to mothers' intention of second childbirth, mediated by maternal parenting stress and marital satisfaction fitted the data of working mothers and non-working mothers well. The results suggest policies focusing on internal characteristics of mothers and dynamics in the family.

This study was conducted to investigate effects of maternal genetic potential and parity with pre- and postpartum periods on body weights, body condition score (BCS) and blood metabolites in relation to physiological stress and nutritional metabolism in Hanwoo cows. Also, this study was designed to develop effective husbandry technique for Hanwoo cows concerning of pre- and postpartum periods, and to get basic data for it. Forty five cows were allocated into two groups, 24 cows with high maternal genetic potentials and 21 cows with low maternal genetic potentials. The average parity of experimental cows with high and low maternal genetic potentials were 2.83±1.63 and 3.00±1.77, respectively. The growth performances such as body weights, average daily gain (ADG) and BCS were not different between two groups regardless of maternal genetic potential. However, pre- and postpartum periods had effects on the growth performances (p<0.05). Parity had no effects on ADG and BCS (p>0.05), but effect on body weight of cows (p<0.05). The metabolites of physiological stress such as neutrophil, hematocrit and cortisol, and nutritional metabolites such as albumin, blood urea nitrogen (BUN), triglyceride, and non-esterified fatty acid (NEFA) concentrations in blood of cows were affected by pre- and postpartum periods in a large scale, while those were partially affected by maternal genetic potential. However, among the metabolites in blood, only neutrophil and triglylceride concentrations were affected by different parity of cows. Therefore, the present study suggests that nutritional intake and digestion are affected by physiological stress due to the parturition, and it should need to consider different husbandry technique based on the maternal genetic potential, and pre- and postpartum periods of cows.

Objectives: This study was conducted to evaluate the maternal child health services provided by public health centers in Pyungtaek city. Methods: Data were collected based on multiple sources of official records. A questionnaire survey was obtained from 50 mothers with premature babies, and 89 mothers with full- term babies, in order to compare their demographic factors, and physical, obstetrical, and emotional status. In addition, the investigators collected data on pre and post follow-up care for the remature group to evaluate the effects of home visiting services on them. Moreover, additional data were collected from 135 pregnant women and 315 mothers with infants, to assess their degree of satisfaction for prenatal education course and breast feeding practices. Results: 1) The pregnant women's satisfaction for the prenatal education course, knowledge, and practices on self care were considered to be high. 2) Of the mothers with infants, 62.9% experienced breast feeding, but only 35.9% of them did it for six months. 3) Premature birth rate in the region was 5.6%, and 75.6% of all premature babies received follow-up care. 4) The mothers with premature babies experienced premature rupture of membrane. placenta previa, preeclampsia, and cesarean section more frequently than the mothers with full-term babies. 5) At the pre-intervention data collection point. mothers with premature babies experienced significantly less social support than mothers with full-term babies. In addition, mothers with premature babies reported higher levels of stress and care-giving burdens, and lower level of self esteem, than mothers with full-term babies, although the differences were not statistically significant. 6) In the premature group, stress, care giving burdens, and postpartum depression decreased after the intervention, whereas maternal self esteem, and the husband's support were increased after the intervention. Social support from significant others were somewhat decreased. 7) Satisfaction for the home visiting service in the mothers with premature babies was very high. Conclusion: These results showed a possibility that the recently started maternal child health services provided by the public health centers may be efficient. Although statistically significant differences were not found, the investigators found a potential for changes in a positive direction. Long-term effects of the health services on maternal child health needs should be addressed in future studies.

Purpose: The purpose of this study was to compare parenting stress between married migrant women and Korean women. Methods: Subjects were 68 married migrant women and 70 Korean women raising children aged seven years or younger, living in three different cities in Gangwon Do. To measure parenting stress, we used Kim's (1997) questionnaire that had been modified from Richard & Abidin's (1990) Parenting Stress Index (PSI). Results: There were significant differences between the two groups in age, academic credentials, job, monthly income, and achievement of maternal role. No statistically significant differences were found for parenting stress scores (p<.355), but there was a significant difference in the child characteristics of parenting stress (p<.007) between the two groups. There were no differences in the demographic variables influencing parenting stress between the two groups. Conclusion: The development of multi-cultural parenting and family support programs should consider the nationality and marital satisfaction of the family.

Purpose: The study examined differences in stress between the parents of sick newborns. Methods: Participants were the mothers (n=57) and fathers (n=57) of newborns in NICU of six university hospitals. An established stress measurement tool (Miles and Carter, 1993) was used. Results: Fathers and mothers displayed the highest stress scores (4.44 and 4.67, respectively) when the baby looked in pain. Maternal overall stress scores were significantly higher than paternal scores. Conclusions: Mothers and fathers experience differing levels of stress concerning their newborn. Further studies are needed to develop customized stress management intervention programs for parents of newborns in the NICU.

This study investigated how mother's thinking styles are represented and researched relationships between their thinking styles, their stress coping styles, and child-rearing stress. Subjects were 254 mothers of children attending child care centers and kindergartens. Instruments were the Thinking Styles Questionnaire Short Version (Sternberg & Wagner, 1991), Parenting Stress Index/Short Form (Abidin, 1990), and the Way of Coping Checklist (Lazarus & Folkman, 1984) Data were analyzed by MANOVA, Pearson's correlation, and regression. Results showed more educated mothers had legislative and internal thinking styles, and mothers employed outside the home had hierarchical, internal, and liberal thinking styles. Varieties of maternal thinking styles were related to parental distress, to parent-child dysfunctional interaction and to child's difficult temperament.

The purpose of this study was to examine the effects of parental beliefs, efficacy and stress on mother's parenting behaviors. The subjects were 243 mothers of two to three-Year-old children in Seoul. The main results showed that parental beliefs, efficacy and stress were significantly related with parenting behaviors. That is, the resets of mutiple regression analysis indicated that parental efficacy, beliefs and stress were significant variables predicting mother's parenting behavior. However, the predictive powers of these variables were different depending on the characteristics of parenting behaviors. And the relationship between mother's parental stress and parenting behaviors was mediated by mother's parental efficacy. To conclude, mother's cognitions such as parental beliefs, parental efficacy, and a perception of parenting stress turned out to be the vital factors in predicting parenting behaviors.

The objective of this study was to identify how child's gender, temperament, mother's stress and their interactions predict parenting behavior. The subjects were 97 2-year-olds(47boys; 50girls) and their mothers. Data were gathered by questionnaires. Results of a series of hierarchical regression analyses showed combinations of variables that predicted parenting behaviors : (1) mothers reported higher over-protectiveness toward girls and when they were under higher stress. (2) An interaction effect showed that mothers with sons who had higher 'difficult' temperaments reported greater over-protective parenting under greater stress. (3) There were no significant differences in over-protective parenting under low stress, regardless of the level of difficult temperament. (4) Mother's stress was a strong predictor of supportive parenting behaviors.
