Purpose: This study was done to identify content of prenatal education and to examine differences in prenatal education, knowledge, and attitude of nulliparous South Korean women. Methods: A cross-sectional survey design was used with 134 conveniently recruited nulliparous women. Data were collected through self-report questionnaires. Results: Average number of institutional prenatal education programs was 5.96 at clinics, 4.31 at health care centers, and 0.49 at hospitals. Women participated in an average 5.78 out of the 35 prenatal education contents: 15 types of prenatal and delivery, 10 postpartum self-care, and 10 parenting. Score for knowledge was 7.57out of 10. Women who participated in prenatal education (n=72) reported significantly higher scores in knowledge (t=2.71, p=.008) than women who did not participate (n=62). The average score for attitude was 7.22 out of 10. Nulliparous women over 36 weeks of gestational age had significantly higher scores for attitude (t=2.38, p=.019) than women under 36 weeks. There were significant positive correlations between newborn care knowledge and postpartum care self-efficacy (r=.26, p=.026), and newborn care knowledge and parenting confidence (r=.25, p=.034). Conclusion: Results indicate that policy is needed to increase participation in prenatal education and to establish strategies for health care centers and hospitals to provide prenatal education.

This study was undertaken to evaluate the prevalence of significant cervical pathology among women who are high-risk human papillomavirus (HR-HPV)-positive/cytology negative, the most common combination of positive co-tests. The records of 244 women HR-HPV-positive/cytology-negative who had undergone colposcopy at Srinagarind Hospital, Khon Kaen University during January 2010 and April 2014 were reviewed. Mean age was 46.4 years. Of these 224 women, 75 were positive for HPV types 16/18 (33.5%) and 123 were positive for non-16/18 types (54.9%). HR-HPV was not genotyped in the remaining 26 women (11.6%). Prevalence of significant lesions for the entire cohort was 2.4%, and 2.6% and 3.3%, respectively, for those with HPV 16/18 and other oncogenic HPV types. One woman with HPV 16/18 (1.3%) had invasive cervical cancer. Multiparous women were more likely to be infected with HPV 16/18 compared to nulliparous women (36.3% versus 17.6%, respectively). In conclusion, the prevalence of significant cervical lesion among our study population was 2.4%. Multiparous women were more likely to be infected with HPV 16/18 compared to nulliparous women.

We conduct this study to compare the difference in duration of labor in nulliparous women received epidural analgesia or non-epidural analgesia for labor pain. This retrospective, observational study based on the review of the medical records from February 2014 to July 2017. Epidural analgesia was initiated with a 10 mL epidural bolus of 1% lidocaine and was maintained with a 0.1% mixture of ropivacaine with fentanyl. Non-epidural analgesia was initiated with pethidine 12.5 mg bolus, followed by additional boluses as needed. The primary outcome was the duration of the labor. 149 healthy nulliparous women at term pregnancies with no evidence of fetal distress were enrolled in this study. 92 women received non-epidural analgesia (Group NE) and 57 women received epidural analgesia (Group E). There were no significant differences between the two groups in maternal demographic characteristics. Using a Kaplan-Meier survival analysis, there was no significant difference in the overall duration of the labor(P=0.233). The duration of the first stage of labor was $187.6{\pm}167.3min$ in Group NE, $248.6{\pm}168.7min$ in Group E (Mean${\pm}$SD, P=0.032). The duration of the second stage of labor was $67.1{\pm}57.8min$ in Group NE, $64.1{\pm}47.5min$ in Group E (Mean${\pm}$SD, P=0.693). Epidural analgesia delayed the first stage of labor in this study. But there were no significant differences between the two groups in the duration of the second stage and the total duration of labor.

Objective : This study was aiming at estimating the joint effects of various risk factors associated with uterine cervix cancer in Korea. Methods : Data obtained from a case-control study were analyzed with a multiplicative model. Results : After adjustment for age and husband's educational attainments, the family history of cervical cancer (OR=2.1, 95% CI=1.2-3.9), unstable marital status due to separation, by death or divorce, etc. (OR=2.8, 95% CI=1.7-4.6), and a large number of deliveries ($\geq$3 vs. nulliparous OR=6.5, 55% CI=1.4-29.0) increased the risk of uterine cervix cancer, Conversely, first sexual intercourse at an older age ($\geq$25 years vs. <19 years OR=0.4, 95% CI=0.2-0.6) and husband's circumcision (OR=0.7, 95% CI=0.5-1.0) decreased the risk. In the multiplicative model, the highest joint risk (OR=39.2, 95% CI 5.9-258.9) was observed in women with a family history of uterine cervical cancer, an unstable marital status, where the ex-husband was not circumcised, with 3 or more delivery experiences, and having her first sexual intercourse when younger than 19 years of age. However, women without a family history of uterine cervix cancer, married to a circumcised husband, having had her first sexual intercourse at 25 years or older, and nulliparous, showed the lowest joint effect (OR=0.3, 95% CI=0.1-0.5). Conclusion : As carcinogenesis is a complex action involving various factors, we consider a joint effects approach to be appropriate in an epidemiological study on risk factors for uterine cervix neoplasms cervix neoplasm.

Primary carcinoma of the fallopian tube is exceedingly rare, accounting for 0.3 percent of female genital tract cancer. It is usually unilateral, but 20 percent of cases are bilateral. It occurs most commonly in women between 40 and 60 years old. Approximately 50 percent of the patients are nulliparous. Because of variable presenting symptoms and rarely incidence, preoperative diagnosis of fallopian tube carcinoma is seldom made. Evaluation and treatment are also essentially the same at that of ovarian carcinoma. We experienced a case of bilateral primary fallopian tube carcinoma in women presented with vaginal bleeding and pelvic mass, postoperatively pathologic examination of resected specimen after laparatomy and reported with brief review of literature.

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 purposes of this study were to predict newborn birthweight by use of gestational period and fundal height and to identify growth curve of fundal height according to gestational period and growth curve of newborn birthweight according to fundal height. The subjects for the study were 802 women who delivered the normal newborn babies at Seoul National University Hospital from Sep. 1, 1981 to Aug.31, 1986. The data were collected bit chart review and analyzed nth SPSS program. The results of study were as follows : 1. The multiple regression equation ($R^2$=0.416) used for the prediction of newborn birthweight was y=(newborn birthweight, kg)=-4.421+0.075$x_1$(fundal height, cm)+0.053$x_2$(gestational period, weeks)+0.016$x_3$(abdominal girth, cm)+0.010$x_4$(maternal height, cm) 2. The growth curve of fundal height according to gestational period was obtained by polynomial regression. The regression equation was Y(fundal height, cm)=-36.78+18.58$log_ex$(gestational period, weeks) The growth curve of newborn birth weight according to fundal height was obtained by polynomial regression. The regression equation was Y(newborn birthweight, kg)=-8.09+3.27$log_ex$ (Fundal Height, cm) 3. In the following subgroups no significant difference was found in fundal height : engaged vs. nonengaged presentation, and nulliparous vs. multiparous women.

This study was conducted to determine whether advancing age is an independent predictor of increased risk of high-grade pathologies among women referred for colposcopy after abnormal cervical cytology. Medical records were reviewed for women with abnormal cervical cytology who underwent colposcopy at Khon Kaen University Hospital. Logistic regression was used to determine the independent impact of age on the risk of high-grade pathologies. Mean age of the women was 42.8 years. Of 482 women, 97 (20.1%) were postmenopausal, and 92 (19.1%) were nulliparous. The rate of high-grade pathologies included cervical intraepithelial neoplasia 2-3, 99 (20.5%), adenocarcinoma in situ, 4 (0.8%), cervical cancer, 30 (6.2%), and endometrial cancer, 1 (0.2%). The prevalence of significant lesions was 26.9% (95% CI, 23.1%-31.2%). In total, 31 women had cancers (6.4%; 95% CI, 4.4%-9.0%). When controlling for smear types and parity, age was noted to be a significant independent predictor of high-grade histopathology. Women older than 35-40 years were approximately 2 times as likely to have severe histopathology as the younger women. This study illustrates the substantial risk of underlying significant lesions especially invasive cancer in Thai women with abnormal cervical cytology. Age was a significant independent factor predicting the risk of high-grade pathologies.

Background: Usually, lumbar epidural block is performed on the $L_{3-4}$ interspace. This study was designed to evaluate the analgesic efficacy and shortening of labor duration comparing the $L_{1-2}$ and $L_{3-4}$ interspace epidural blocks in nulliparous normal vaginal deliveries and then investigates side effects following the blocks. Methods: Eighty healthy nulliparous women were divided into two groups, $L_{1-2}$ (n = 40) and $L_{3-4}$ (n = 40). Epidural blocks, lumbar epidural block were performed at the $L_{1-2}$ and $L_{3-4}$ interspace with a catheter advancing 3 cm cephalad. The initial dose of 12 ml (0.167% bupivacaine, fentanyl $50{\mu}g$ and clonidine $75{\mu}g$) was injected epidurally at 4 cm dilatation of cervix and severe pain of labor. If a visual analogue scale (VAS) score was more than 4 points, an additional dose was administered epidurally using the same volume as the above mentioned, but with the exception that the bupivacaine was diluted to 0.1 percentage. The maternal blood pressure, pulse rate, respiration rate and fetal heart rate were measured at 10 min intervals for the first 30 min, at 15 min interval for the next 30 min and at 30 min interval for the last one hour following the blocks. The duration of the first (active) and second stages of labor was counted and the neonatal Apgar score was recorded at one and five min after delivery. The degree of motor block, pruritus, nausea and vomiting were also noted. Results: The patients in group $L_{1-2}$ had lower pain scores than group $L_{3-4}$ at 5, 20, 30, 60 mins. The duration of 1st and 2nd labor stage in the $L_{3-4}$ epidural block were $272{\pm}33.5$ min, $49.2{\pm}27.4$ min respectively but those in the $L_{1-2}$ epidural block were $253.5{\pm}32.5$ min, $37.3{\pm}22.3$ min, respectively. Conclusions: We concluded the analgesic efficacy and shortening of labor duration in $L_{1-2}$ epidural block was better than those in $L_{3-4}$ epidural block. Maternal hemodynamic change, motor block. pruritus, nausea, vomiting and Apgar score showed no significant differences between the two groups.

Objectives : The purpose of this study is to investigate the differences of pulse wave parameter between the non delivery group (single women with no childbirth experience) and the delivery group (married women who gave birth(s) in delivery). Methods : Sixty one healthy (non delivery) nulliparous women and fifty three delivery women participated in this study. We used 3 dimensional pulse analyser(3D MAC, DAEYOMEDI co., Korea), which measures radial pulse waveform non-invasively by way of tonometry method at 5 different applied pressure levels. From 114 subjects enrolled, pulse wave parameters were measured on the six locations of Chon, Kwan and Cheok of each hands. Results : Delivery group's pulse showed larger values in the following pulse wave parameters (Energy, Ap, RAI, As, Aw, h1, h2, h4, h4/h1, t, t1, t2, t4, Wm, Wm/t). Non delivery group's pulse indicated larger values in the pulse wave parameters such as Energy of left Chon, difference pulse energy between left and right hand, Ad, h5, h5/h1, t5. Conclusions : According to the analysis result, delivery group's pulse has bigger values in most part of pulse wave parameters, especially in Kwan and Cheok which correspond to Liver, Kidney, and Myeong-mun. We interpret these results that delivery women are more mature and stable in reproductive organs than non delivery group, as they have experienced delivery(deliveries) and child-caring through married life.
