The purposes of this descriptive survey study were to describe antenatal depression and level of mother-fetal interaction, and to assess mother's behavior and feeling during mother-fetal interaction, in order to develop a base for nursing intervention programs for mothers who have antenatal depression. Method: Data were collected from 174 pregnant women who visited one public health center and OBGY clinic in Gangneung city. The instrument used for this study was a self-report questionnaire to identify depression (BDI), and mother-fetal interaction. Results: Of the mothers 63.2% were in the normal range for antenatal depression, 21.3% in the mild group and 15.5% were in the moderate to severe group. For antenatal depression, there were significant differences among the income, planned pregnant, health status, marriage satisfaction, family support, husband's love. The mean for mother-fetal interaction was $29.88{\pm}4.91$. For mother-infant interaction, there were significant differences in education, income, pregnant number, delivery number, feeding plan, marriage satisfaction, family support, husband's love. There was a weak correlations between antenatal depression and mother-fetal interaction but it did not reach statistical significance. Conclusion: Antenatal depression and mother-fetal interaction influence fetal development. It is essential to assess and provide immediate care to mothers who have antenatal depression and lower level mother-fetal Interaction.

Purpose: Prenatal depression is associated with potential negative consequences for the mother and infant. The purpose of this study was to examine pregnant women's stress, and depression and their impact on maternal-fetal attachment and fetal growth. Methods: Data were collected by means of a questionnaire and fetal sonogram from a convenience sample of 166 pregnant women. Results: Women who have a low educational level, poor health and are dissatisfied with their marriage showed low maternal-fetal attachment. Prenatal depression had significant correlations with length of pregnancy and level of stress. Even though correlation between maternal stress and fetal weight (r=-.15, p=.099) and correlation between maternal depression and maternal-fetal attachment (r=-.13, p=.095) were not statistically significant, the impact of the prenatal psychological state of mothers can not be ignored as it relates to fetal health. Conclusion: Maternal-fetal attachment and fetal growth can be affected by maternal emotional state, including stress or depression. These findings suggest that primary care nurses in hospitals and public health centers should provide prenatal depression screening and nursing intervention programs for management and prevention of prenatal stress and depression.

Purpose: This study was conducted to examine the relationships among the perceptions and practice of taegyo (a traditional set of practices and beliefs related to healthy fetal development) and maternal-fetal attachment in pregnant women. Methods: The participants were 136 pregnant women who visited a public health center or maternity hospital for prenatal care. The collected data were analyzed using descriptive statistics, the t-test, analysis of varience, and Pearson correlation coefficients with SPSS version 22.0. Results: The mean age of the pregnant women was $32.24{\pm}3.99$ years. The mean scores for perceptions of taegyo, practice of taegyo, and maternal-fetal attachment were $3.96{\pm}0.53$, $3.74{\pm}0.64$, and $3.94{\pm}0.49$, respectively. Perceptions of taegyo were significantly correlated with the practice of taegyo (r=.72, p<.001), and maternal-fetal attachment (r=.55, p<.001). A significant correlation was also found between the practice of taegyo and maternal-fetal attachment (r=.65, p<.001). Conclusion: Perceptions of taegyo affected the practice of taegyo, and had a positive effect on maternal-fetal attachment. These findings suggest that primary care nurses at hospitals and public health centers should provide nursing intervention programs to improve the perceptions of taegyo, the practice of taegyo, and maternal-fetal attachment.

Purpose: Coronavirus disease 2019 (COVID-19) has spread widely throughout the world, causing psychological problems such as fear, anxiety, and stress. During the COVID-19 pandemic, pregnant women have been concerned about both their own health and the health of their fetuses, and these concerns could negatively affect maternal-fetal attachment. Thus, this study aimed to explore the level of COVID-19 stress, resilience, and maternal-fetal attachment among pregnant women during the COVID-19 pandemic, and to identify factors influencing maternal-fetal attachment. Methods: In total, 118 pregnant women past 20 weeks gestation were recruited from two maternity clinics in Daegu, Korea, to participate in this descriptive correlational study during COVID-19. The factors influencing maternal-fetal attachment were analyzed using hierarchical multiple regression analysis. Results: The mean scores for COVID-19 stress, resilience, and maternal-fetal attachment were 57.18±10.32 out of 84, 67.32±15.09 out of 100, and 77.23±9.00 out of 96, respectively. Nulliparous pregnant women reported greater maternal-fetal attachment than multiparous pregnant women (p=.003). Religious pregnant women also reported greater maternal-fetal attachment than non-religious pregnant women (p=.039). Resilience (β=.29, p=.002), COVID-19 stress (β=.20, p=.030) and parity (β=-.17, p=.047) were factors influencing maternal-fetal attachment, and these factors explained 26.4% of the variance in maternal-fetal attachment (F=10.12, p<.001). Conclusion: Converse to common sense, COVID-19 stress exerted a positive influence on maternal-fetal attachment in pregnant women during the COVID-19 pandemic. Healthcare providers need to recognize the positive influence of COVID-19 stress and implement intervention strategies to strengthen resilience in pregnant women to improve maternal-fetal attachment.

The characteristics of health behavior related pregnancy and childbirth have reflected on the cultural belief and value in the society. The efforts for women's health promotion through the current illumination of the traditional health care are the prompting assignment to be in nursing. The process of motherhood already progress before the motherhood actually. The functional state as the expectant mother can be the important predicting factor of the postpartum state, the quality of a married life. Motherhood was analyzed by Walker and Avant's method to clarify the concept 'to be a mother' using the various concepts like Koreans' Taekyo, transition to motherhood, maternal identity, maternal role attainment, maternal fetal attachment, and maternal fetal interaction. Upon the concept analysis, naturalness, responsibility, attachment, readiness, controllability were identified as the defining characteristics of motherhood. The antecedents of motherhood were consist of maternal affection, positive self esteem, pregnancy acceptance, fetus recognition and the consequences of motherhood were consist of positive maternal identity, maternal fetal attachment, confidence about the maternal role, the healthy mother and the healthy baby. The empirical referents of motherhood were consists of recognition of motherhood, expectation about motherhood, fetal recognition with ultrasonography and fetal movement, experience of unification between mother and fetus, expression of affection to the fetus, concern about fetal health, concern and practice about Taekyo, adaptation behavior about physical change and discomfort due to pregnancy. Therefore it is necessary to develop the instruction program of motherhood including the defining attributes identified in this study.

Purpose: Smoking during pregnancy contributes to the risk of negative health outcomes in mothers and babies. The purposes of this study were to review the harmful effects of maternal smoking during pregnancy on fetal and child development, to discuss if maternal smoking should be criminalized as a form of child abuse, and to explore advocating for fetal rights. Methods: A variety of published literature and legal documents including the Korean constitution, criminal laws, and children's welfare laws were reviewed and critically analyzed. Results: Women who smoke during pregnancy are more likely to experience abortion related to placental dysfunction. Their unborn risk premature birth, fetal growth restriction, low birth weight, neurobehavioral disturbances, and/or other complications and newborn babies are also at risk for complications. The advocates for fetal rights can assert that maternal smoking should be regarded as a crime. Conclusion: Findings show that maternal smoking during pregnancy is a major risk factor for many adverse pregnancy outcomes. Effective strategies and health policies for smoking cessation during pregnancy are required to protect pregnant women and their babies.

The purpose of this study was to perform the fetal education effectively for the delivered woman and her husband. This study was conducted by the questionnaire survey on 199 delivered women and their 171 husbands at several hospitals located in Seoul and Kyonggi Province from February 28 to March 26, 2002. The contents of questionnaire included the purposes, the cognition and the practice of fetal education. The SAS program was used for the statistical analysis of the data. The character of subject was analyzed by the percentage. The difference between the cognition and practice of fetal education was analyzed by t-test, ANOVA, Wilcoxon rank sum test. The factor analysis affected on the practice of fetal education was adopted by Multiple regression. The results were as follows; 1. In the purpose of fetal education, the well- balanced emotion showed the highest mark. The cognition of fetal education(woman:$4.39{\pm}0.52$, husband:$3.88{\pm}0.70$) and the practice (woman:$3.88{\pm}0.60$, husband:$3.83{\pm}0.70$) showed the relatively high mark, but the score of cognition showed higher than that of practice. 2. In the comparison of the cognition between the delivered woman and the husband for the fetal education the item of the mental or health state would affect unborn baby, which occupied the highest mark in both woman and the husband(woman:$4.81{\pm}0.44$, husband:$4.81{\pm}0.50$). But they were prohibited to eat the deformed food, which showed the lowest mark(woman:$3.19{\pm}1.12$, husband:$3.21{\pm}1.29$). 3. In the comparison of the practice for the fetal education between the delivered woman and the husband, the practice for the healthy baby showed the highest mark in woman ($4.51{\pm}0.71$), which had a statistically significant difference(P=0.025), compared with that of the husband($4.13{\pm}0.99$). 4. In the comparison of cognition and practice for the fetal education, the general character was associated with the duration of marriage, the satisfaction with marriage and the support of husband on pregnancy. The mark was associated with the age of woman, the level of education and the first birth. 5. The significant factors influencing on the practice for the fetal education were connected with the cognition of fetal education, age, satisfaction with marriage, the support of husband on pregnancy, the type of family, the experience of delivery and the state of health during the period of pregnancy. etc. In conclusion, it is indicated to make effort for transforming and developing the traditional fetal education in accordance with the modern fetal education. And it is suggested that the fetal education might be recognized by all members of family, and the importance of husband's role for the fetal education should be informed as well as that of woman's.

In this paper, we proposed a new algorithm for the separation of fetal ECG from single channel abdominal ECG. The algorithm consists of a stage of demixing vector calculation for initial signal and a stage of fetal beat detection for the rest of signal. The demixing vector was obtained by applying independent component analysis technique to projected signals into time-frequency domain. For the test of this algorithm, simulation signals, De Lathauwer's data and some measured data, which was acquired from 8 healthy volunteers whose pregnant periods ranged from 22 weeks to 35 weeks and whose ages from 27 to 37, were used. For each data, the accuracy of fetal beat detection was $100\%$ and with the location of fetal beats, fetal heart rate variability and morphology could be offered. In conclusion, this proposed algorithm showed the possibility of fetal beat separation with a single channel abdominal ECG and it might be adopted to a fetal health monitoring system, by which a single channel abdominal ECG is acquired.
