Purpose: This study aimed to identify the effects of a direct breastfeeding program for premature infants in neonatal intensive care units (NICUs). Methods: This quasi-experimental study was conducted during August 2016 to April 2017. Sixty mothers of premature infants were assigned to the experimental (n = 31) or control groups (n = 29). The program was comprised of breastfeeding education and direct breastfeeding support. The experimental and control groups were provided with education and counseling on breastfeeding at the time of admission and discharge. In the experimental group, the mothers initiated oral feeding with direct breastfeeding and engaged in breastfeeding at least seven times during the NICU stay. The collected data were analyzed by the χ2-test and repeated measures ANOVA using an SPSS program. Results: The experimental group showed a higher direct breastfeeding practice rate (χ2 = 19.29, p < .001), breastfeeding continuation rate (χ2 = 3.76, p < .001), and self-efficacy (F = 25.37, p < .001) than the control group except for maternal attachment. Conclusion: The direct breastfeeding program in the NICU has significant effects on the practice and continuation rate of breastfeeding and breastfeeding self-efficacy. Therefore, this program can be applied in the NICU settings where direct breastfeeding is limited.

Pregnant Yorkshire gilts were utilized to investigate the efficacy of exogenous administration of pST and/or insulin in enhancing prenatal piglet survival, uteroplacental and umbilical cord growth and development. Gilts were randomly assigned in a $2{\times}2$ factorial arrangement to four treatment combinations consisting of either daily i.m. injections of 5 mg pST (P, n=23); 0.50 IU/kg of insulin (I, n=23); combination of pST and insulin (P+I, n=23); or 1 ml of saline as control (C, n=23) from gestation Day 30 to 70. All gilts were sacrificed on gestation d 113 to evaluate piglet survival and uteroplacental or umbilical cord development Uteri were longer (346.3 vs 325.7 cm; p<0.05), and heavier (3122.8 vs 2940.7 g; p<0.05) in insulin treated gilts. Only placental macroscopic surface area was enhanced by maternal insulin injections (p<0.05) Incidence of umbilical cord abnormalities were low (14.3%), and they were independent of maternal treatment, occurring more in short cords than in long ones (21 vs 12%; p<0.05). A 6% increase in cord length (53.2 vs 48.6 cm; p=<0.05) was observed in piglets from treated gilts compared with controls. Significant sex differences (in favour of males) were observed in piglet weight, crown rump length and for most umbilical or placental parameters. Gilt weight gains from breeding to Day 113 of gestation were 10% and 15% greater in pST and insulin treated gilts compared with controls. These data indicate that prepartum injections of pST and/or insulin to gestating gilts seem to have a beneficial effect on uteroplacental or umbilical cord development and promote conditions conducive for perinatal piglet survival.

Purpose: This study was intended to evaluate the effects of an Infant Health Promotion Program (IHPP) for mothers with their firstborn infants. Methods: This study employed a non-equivalent control group pretest-posttest design. The participants consisted of 17 mothers with their firstborn infants in the experimental group and 17 in the control group from two women's hospitals. The experimental group received eight sessions of the program for four weeks. The collected data were analyzed using the chi-square test and repeated-measures ANOVA using an SPSS/WIN ver. 22.0. Results: The experimental group receiving the program had statistically significant higher levels of infant health promotion knowledge (F = 22.91, p < .001), social support (F = 27.64, p < .001), maternal role confidence (F = 8.25, p = .005) and health promotion behavior for infants (F = 16.85, p < .001) than the control group. The experimental group had a statistically significant lower level of parenting stress than the control group (F = 29.93, p < .001). Conclusion: The study's findings indicate that the IHPP is effective in improving health promotion knowledge, social support, and maternal role confidence and decreasing parenting stress among mothers with their firstborn infants. A method of delivering intervention, focused on readily accessible online platforms, coupled with intervention strategies grounded in the theory of self-efficacy, proves to be an advantageous approach for this particular target group.

Background/Aims: There have been numerous efforts to reduce mother-to-child transmission (MTCT) of hepatitis B virus (HBV) with antiviral agents during pregnancy. However, there are limited data regarding the outcomes of pregnant women after delivery. This study was performed to evaluate the efficacy of antiviral agents in preventing MTCT of HBV and maternal long-term outcomes. Methods: The HBV-infected pregnant women treated with antiviral agents to prevent MTCT were retrospectively reviewed. Forty-one pregnant women who received telbivudine or tenofovir during late pregnancy (28-34 week) were analyzed. Hepatitis B virus surface antibody (HBsAb) positivity was tested in 43 infants after 7 months of birth. Eleven mothers were followed >1 year after delivery. Results: The mean HBV DNA titer before antiviral therapy was 8.67 (6.60-9.49) log copies/mL, and the median age at delivery was 32 years (range, 22-40). Eleven patients were treated with tenofovir and 30 with telbivudine. The median duration was 57 days (range, 23-100), and the median HBV DNA titer at birth was 5.06 log copies/mL (range, 2.06-6.50). Antiviral treatments were associated with significant HBV DNA reduction (P<0.001). Among 43 infants (two cases of twins), HBsAb was not detected in two, subsequently confirmed to have HBV infection. Biochemical flare was observed in two of 11 mothers followed >12 months, and an antiviral agent was administered. Conclusions: Antiviral treatment during late pregnancy effectively reduced MTCT. Long-term follow-up should be required in such cases. In addition, given that maternal biochemical flare occurred in 18% of mothers, re-administration of antiviral agents might be required.

The present study employed a pretest-posttest quasi-experimental design model in order to evaluate the effectiveness of the Respected Parents & Respected Children (RPRC) parent education program for mothers of early school-age children. Ninety mothers were randomly assigned to an intervention (n=45) group or a control group (n=45). Mothers in the intervention group participated in 8 weekly sessions of the parent education program. After the termination of the program, the differences between pretest and posttest were analyzed in terms of both maternal parenting characteristics (i.e., parenting behavior, parenting efficacy, parenting stress, and co-parenting) and children's social competence. The results indicated that only in the intervention group, self-reported positive parenting characteristics were significantly improved and negative parenting characteristics were significantly decreased. There were no significant effects of the program on children's social competence as rated by the mothers. These findings suggest that the RPRC parent education program is effective in changing parenting characteristics known as crucial predictors of child outcomes.

Injury has now replaced disease as the biggest single cause of death in children after their first birthday. Each day child dies from preventable, unintentional injury and the medical cost of these injury is increasing remarkably. It is necessary to develope injury prevention models to explain, predict, manage, evaluate and analyze the information about accident. The purpose of this paper is, firstly, to investigate parent's actions regarding safety measures at home and secondly, to identify the influencing factors of parents' safety behaviors. The selection of such factors is guided by the theoretical framework of the Pender's Health Promotion Model. Method ; The questionnaire was developed on the basis of other investigations, through pilot testing, peer review, and review by field health workers. The questionnaire was completed by 231 mothers of young children. Data was collected between April and May 2002. Variable Use of three different domains of safety behavior, safety habits, supervision and perception of safety devices, were listed. Mothers were self reported on internal locus of control, mother & child relationships, and marital intimacy. Also the elements of the Health Promotion Model: perceived benefit, barrier, threat, and self-efficacy, were surveyed. Results & discussion The results indicate that most parents take considerable action to reduce household hazards. The constructs derived from the Model were statistically significant differences for a small part of the variables on parental behavior to reduce hazards in the home, such as age, education, economic status, self-efficacy, perceived benefit, internal locus of control. Future studies ought to include social influences, such as expectations, perceived norms, knowledge, and child-related variables, relevant to parental safety measures in their home.

Purpose: This study developed a self-report measure for easy assessing of the health literacy of Asian immigrant women in South Korea. Methods: After a literature review, focus group interviews, and content validity evaluation, 14 preliminary items were generated. These were translated into Chinese, Vietnamese, and English. Data were collected from 229 Asian immigrant women. Validity and reliability tests were conducted. Results: Factor analysis yielded final 10 items in three factors: primary functional and interactive health literacy, secondary functional and interactive health literacy, and critical health literacy, which explained 61.90% of the total variance of health literacy. In known-group comparisons, health literacy was significantly lower in recent immigrants, those with a low education level, and those with low Korean language proficiency. For convergent validity, health literacy was positively associated with health specific self-efficacy and maternal health knowledge. For criterion-related validity, health literacy was positively associated with the REALM-SF. The overall reliability coefficient (Cronbach's ${\alpha}$) of the instrument was .773. Conclusion: The Health Literacy Assessment Scale for Asian Immigrant Women (HLAS) represents a multidimensional construct which encompasses functional, interactive, and critical health literacy. This self-report HLAS can be a useful and convenient method for appraising the health literacy of Asian immigrant women.

Objectives Recently, vitamin D supplements to breast-fed infants are being encouraged in Korea, and other countries. However, the reliability and validity assessment of supplements is insufficient. Therefore, this study suggests new Korean guidelines for vitamin D supplements of breast-fed infant. Methods The roles of Vitamin D for bone metabolism in children and the correlation between breast milk and Vitamin D were examined throughout domestic and international literature review. In addition, the efficacy and safety of vitamin D supplements were reviewed. Results Preventive effects of rickets by vitamin D supplementation remain unclear. Furthermore, concerns about the safety of vitamin D supplements intake have been raised. Korean guideline suggests breast-fed infants can get vitamin D through the skin safely, but maternal intake of vitamins through sunbath and diet is more effective and safe. Conclusions Limiting sunlight excessively and applying foreign countries' medical guideline for vitamin D supplements are not valid to apply as a domestic guideline for Korean breast-fed infants without considering ethnic and cultural characteristics.
