Purpose: The purpose of this study was to identify the relations among supports during childbirth, attitudes toward childbirth presence, and the childbirth experiences in husbands. Methods: The participants in this study were 178 husbands whose wives were within 2 days after normal spontaneous vaginal delivery. Data were collected from September 1st to September 30th, 2013. Results: The significant factors affected on the childbirth experiences in husbands were attitudes toward childbirth presence (${\beta}=.61$), satisfaction for the nurse's cares during childbirth (${\beta}=.19$), psychological preparation for childbirth (${\beta}=.16$), baby weight (${\beta}=.09$), and prenatal education related to pregnancy (${\beta}=.09$). These variables explained 66% of the childbirth experiences in husbands. Conclusion: It would be necessary to develop nursing intervention programs that increasing positive attitudes toward childbirth presence, psychological preparation for childbirth, and prenatal education to increase positive childbirth experiences in husbands. Nurses should also provide husbands with satisfactory cares during childbirth.

Purpose: The purpose of this study was to evaluate the effects of Doula support during labor on anxiety, labor pain, and perceived childbirth experience of primiparas. Method: Of 65 primiparas who were hospitalized in LDR from March 1 to September 30, 2007. 32 women were placed in the Doula group and 33 in the control group. VAS was used to measure the degree of labor pain and anxiety in the latent, active, and transitional phases. Perceived childbirth experience was measured within 2 hours after birth. Results: The Doula group had a significantly lower anxiety level than the control group in the active phase (t=-2.13, p=.04) and the transitional phase (t=-3.99, p=.000). The degree of labor pain of the Doula group was significantly lower than that of the control group for the active phase (t=-3.10, p=.003) and the transitional phase (t=-7.24, p=.000). Also, There was no significant difference in perceived childbirth experience between the two groups (t=.19, p=.85). Conclusion: The results of this study show Doula support in LDR decreases not only anxiety of primiparas but also labor pain in the active and transitional phases. Therefore Doula support by nurses in LDR can be a useful intervention during childbirth.

A novel technology for homogeneous deposition of zeolite particles on a porous support was developed so that those particles played a seeding role for the growth of zeolite crystals. After the particles were dispersed in water, the aqueous solution was 134 through the bore of a porous tubular support. By keeping the other side of the support in a vacuum, the aqueous solution passed through the pores of the support, leading the particles to be homogeneously deposited on the support. The amount of the deposited particles was investigated by changing the following operating parameters: a particle concentration in the solution, a time for deposition, and the feeding rate of the solution. The amount of the deposited particles increased from 0.0019 g to 0.0208 g as the concentration of the particles was changed from 0.01 wt% to 0.3 wt%, while the feeding rate and the deposition time were kept to 100 mL/min and 4 min, respectively. As the deposition time was varied from 1 min to 4 min, the deposition amount increased from 0.0004g to 0.0019g at the typical condition of the rest parameters. Also, it was observed that the deposited weight increased from 0.0029 g to 0.01 g as the feeding rate increased from 100 mL/min to 300 mL/min. However, the total permeance of water and ethanol decreased through the zeolite membrane as the deposited weight increased.

Purpose: This study was done to investigate the point prevalence of postpartum depression and its predictors during early postpartum in mother of preterm infants. Methods: Participants were 101 women, 2-3 weeks after delivery whose preterm babies were hospitalized in a neonatal intensive care unit. Data were collected from June 2010 to January 2011. The instruments included 'Edinburgh Postnatal Depression Scale', 'Prenatal depression', 'Subjective health status of infant', 'Medical staff support', and 'Husband support'. Collected data were analyzed using t-test, ${\chi}^2$-test, and multiple logistic regression with SPSS/WIN version 18.0. Results: The point prevalence was 86.1% that postpartum depression occurred during the early postpartum period in mothers of preterm infants. Three significant predictors of postpartum depression in mothers of preterm infants were identified; 'Type of delivery (OR, 5.57; 95% CI, 1.25-24.77)', 'Subjective health status of infant (OR, 0.34; 95% CI, 0.16-0.70)', and 'Medical staff support (OR, 0.52; 95% CI, 0.28-0.97)'. Conclusion: The results indicate that postpartum mothers should be screened for postpartum depression early in the postpartum period and that, medical personnel should pay particular attention to mothers with a caesarean section and should help mothers of preterm babies to develop positive perceptions of their babies.

Carbon coils could be synthesized using $C_2H_2/H_2$ as source gases and $SF_6$ as an incorporated additive gas under thermal chemical vapor deposition system. The Ni layer on the $SiO_2$ substrate was used as a catalyst for the formation of the carbon coils. The characteristics (formation densities, morphologies, and geometries) of the as-grown carbon coils on the substrate with or without the $H_2$ plasma pretreatment process were investigated. By the relatively short time (1 minute) $H_2$ plasma pretreatment on the Ni catalyst layered-substrate prior to the carbon coils synthesis reaction, the dominant formation of the carbon microcoils on the substrate could be achieved. After the relatively long time (30 minutes) $H_2$ plasma pretreatment process, on the other hand, we could obtain the noble-shaped geometrical nanostructures, namely the formation of the numerous carbon nanocoils along the growth of the carbon microcoils. This noble-shaped geometrical nanostructure seemed to play a promising role as the good catalyst support for holding the very tiny Ni catalyst grains.

Purpose: To identify and clarify the concept of labor support. Methods: This study used Schwartz-Barcott & Kim's hybrid model to identify the main attributes and indicators. In the fieldwork stage, data were collected in Seoul and Chenmam, Korea. The participants were five nurses working in the delivery room and four women who delivered more than two children by vaginal delivery. Results: The concept of labor support was found to have nine attributes and 23 indicators in two dimensions. For the physical intervention dimension, five attributes were derived. They were pain relief, selective use of technology, ambulation/positioning, physiological pushing, and increasing comfort. For the labor support practices dimension the attributeswereprovidinginformation, relief and encouragement, family support, and presence. Conclusion: The concept analysis of labor support in this study could provide guidelines for 'labor support' nursing practice and be useful for research in the women's health field.

This study examined 191 pregnant women before delivery in an obstetrics and gynecology clinic in North Gyeongsang Province from May to September 2016 by using a questionnaire after obtaining informed consent for voluntary participation in the study. The study was performed to investigate the association of depression with sociodemographic characteristics, pregnancy-related characteristics, social support, sleep quality and Oral Health Impact Profile (OHIP) in pregnant women. The prevalence of depression among the pregnant women was 25.1% in the healthy group and 74.9% in the depression group. The depression level was significantly higher in women in the depression group who were unsatisfied with their marriage life, had no occupation, had lower social support, had poor sleep quality and had higher OHIP scores. The results of the logistic regression analysis indicated that, the risk ratio for more severe depression was significantly higher in the group with no experience of miscarriage and induced childbirth than in the group with childbirth experience. Conversely, the risk ratio for more severe depression was significantly lower in the group with high social support than in the group with low social support. Depression in the respondents significantly positively correlated with sleep quality and OHIP score but significantly negatively correlated with social support. The multiple regression analysis revealed that the depression level was significantly higher by 22.3% among pregnant women with lower marital satisfaction, no childbirth experience, lower social support and higher OHIP scores. In summary, depression was related to marital satisfaction, childbirth experience, social support, and OHIP score, among others, in pregnant women in this study. Therefore, further investigation is warranted to construct programs and measures that will help build positive thinking by designing and verifying a three-dimensional study model by taking into consideration various variables to reduce the incidence of depression in pregnant women.

Purpose: Maternal-fetal attachment in a pregnant woman is important for her health and for her child's emotional stability. This study was done to identify the contribution of maternal fatigue, social support, and Taegyo to maternal-fetal attachment based on a survey of pregnant women. Methods: The study was a descriptive correlation study. Participants were 211 from two women's health clinic centers. Data were analyzed using t-test, ANOVA, Pearson correlation coefficients and stepwise multiple regression. Results: Mean scores for maternal-fetal attachment, Taegyo, maternal fatigue, and social support were 93.74 (range 25-125), 64.76 (17-85), 24.12 (10-40), and 54.43 (22-132), respectively. There were significant differences in maternal-fetal attachment according to parity, breast feeding experience, and putting prenatal education into practice. Multiple regression analysis showed that the key determinants of maternal-fetal attachment, were Taegyo (${\beta}$=.67), maternal fatigue (${\beta}$=.21), and social support (${\beta}$=.13), and these explained 55% of the total variance of attachment. Conclusion: The results suggest a need to encourage Taegyo in prenatal management program and provide methods for fatigue resolution and promotion of social support.
