Objective: to investigate pertussis vaccination rates during pregnancy and the routine recommendation rates by maternity healthcare professionals (HCPs), including influencing factors, in Korea. Materials and methods: Two different questionnaires were developed and conducted anonymously for pregnant or postpartum women and maternity HCPs in 30 multi-centers. Maternal pertussis vaccination rates and maternity HCPs’ recommendation rates were analyzed. Independent influencing factors were analyzed using multivariate logistic regression analysis, respectively. Results: The rate of pertussis vaccination during pregnancy among 466 women was 67%. Among 164 multiparous women, 35.5% received pertussis vaccinations during every pregnancy. However, 27.9% among all pregnant women did not receive information about pertussis and vaccination. The independent influencing factors for maternal pertussis vaccination, given as the tetanus, diphtheria and acellular pertussis (Tdap), were “getting informed” (OR 18.597, 95% CI 11.206–30.861), “informed by OBGYN doctors” (OR 4.426, 95% CI 2.144–9.267), and “metropolitan residence” (OR 3.048, 95% CI 1.419–6.548). Among a total of 373 maternity HCPs, 210 (56.3%) routinely recommended pertussis vaccination, but 21.7% of the total maternity HCP participants did not know the maternal Tdap guideline. The independent factors affecting routine recommendation were the awareness of guideline (OR 9.771, 95% CI 5.227–18.265, p

The purpose of this study is to investigate the effect of Grit on career decision making self-efficacy and career preparation behaviors of university students in physical education. The purpose of this study is to examine the effect of Grit on university students in physical education in Seoul and Gyeonggido. The data were analyzed by frequency, factor analysis, correlation analysis, regression analysis, and structural equation modeling using SPSS 21.0 program and AMOS 21.0 program. Based on the results and discussions, the following conclusions were obtained. First, all variables such as steady effort and continuous interest, which are sub-factors of Grit, had a positive influence on all of the sub-factors of career decision making self-efficacy, such as goal selection, future planning and job information. These results indicate that Grit is a very important variable to enhance career decision making self-efficacy. Second, all variables such as steady effort and continuous interest, which are sub-factors of Grit, had a positive influence on career exploration behavior, information gathering behavior, and job experience behavior. These results indicate that Grit is a very important variable for enhancing career preparation behavior. Third, all variables such as goal selection, future plan, and job information, which are sub-factors of career decision making self-efficacy, have positive significance in career exploration behavior, information gathering behavior, It affected. These results indicate that career decision making self-efficacy of university students is a very important variable to enhance career preparation behavior. Fourth, the relationship among Grit, career decision making self-efficacy and career preparation behavior was confirmed, and it was confirmed that there was a positive causality between each variables.

This study aims to investigate the independent influence of maternal age on the risk of emergency cesarean section (CS) due to nonreassuring fetal heart rate or arrest disorder.This was a cross-sectional study on women with nulliparous pregnancies, who are attempting vaginal delivery at term and have a cephalic presentation without the indication of elective CS at the onset of labor. The primary outcome was the rate of emergency CS. Independent risk factors were elucidated using multivariate logistic regression analysis.Of 3513 women, 541 (15.4%) delivered by emergency CS during a trial of vaginal delivery, with theses being due to nonreassuring fetal heart rate (N = 150) or arrest disorder (N = 391). In univariate analysis, both individual CS rate due to nonreassuring fetal heart rate or arrest disorder and total emergent CS rate increased with maternal age. The risk of emergency CS was also significantly higher when labor induction was performed (odds ratio (OR) 2.489, 95% confidence interval (CI) 2.043-3.033), while fetal weight was heavier (neonatal weight ≥3.5 kg; OR 2.396, 95% CI 1.956-2.934), and maternal BMI was higher (before pregnancy ≥25 kg/mAdvanced maternal age is an independent risk factor of emergency CS due to nonreassuring fetal heart rate or arrest disorder during the trial of vaginal delivery. The risk of emergency CS was also increased when labor induction was performed. Therefore, the risk of emergency CS needs to be considered, especially when the labor induction is planned, in women aged 40 or more.

The aim of this study was to examine the current perinatal outcomes among infants born late-preterm and early-term compared to those born full-term and evaluate the optimal gestational age for delivery.We performed a retrospective cohort study for births occurred at Seoul St. Mary's Hospital over the past 7 years. Statistical comparison was performed using χA total of 7580 women met the study criteria. Compared to 39 weeks, delivery at late-preterm and early-term had higher risk of composite morbidity, including respiratory morbidities, intracranial hemorrhage (ICH), and admission to neonatal intensive care unit (NICU) (34 weeks adjusted odds ratio [aOR]: 132.54; 95% confidence interval (CI): 74.00-240.10; 37 weeks aOR: 2.14; 95%CI: 1.65-2.77). The risks of sepsis and necrotizing enterocolitis in deliveries before 36 weeks and the risk of feeding difficulty in deliveries before 37 weeks were significantly higher than those of 39 weeks. Neonatal morbidity at deliveries was not significantly different between 38 and 39 weeks.Neonatal morbidities at late-preterm births are significant and surveillance for them seems increasing. Obstetricians should recognize the risk of respiratory morbidity, ICH, and NICU admission for deliveries before 38 weeks' gestation.

Objective: The aim of this study was to analyze the relationship between maternal origin and risks of term low birth weight (TLBW) or macrosomia in Korea. Methods: Using Korean birth statistics from 2009 to 2015, we examined the association between maternal nationality and risks of TLBW (less than 2.5 kg) or term macrosomia (over 4.0 kg). Birth statistics included singleton live births in women, from 37 to 41 weeks’ gestation, during the period 2009-2015. Immigrant mothers were defined as women born in any country other than Korea, and were grouped by economic level of maternal country of origin. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated with multivariate logistic regression analysis. Results: There were significant differences in neonatal birth weights between Korean mothers and immigrant mothers (3.28±0.38 kg vs. 3.24±0.39 kg, P

An agar-degrading enzyme-producing strain was isolated from seawater. The isolate was identified as Microbulbifer sp. SD-1 by 16S rRNA sequencing analysis. The optimal pH and temperature for growth were 6.0 and 30°C, respectively, and growth was pos- sible at pH 9.0 and 60°C. The isolate required 5% NaCl for optimal growth and showed 45% growth activity without NaCl. Agar concentrations of 0-0.4% in the medium did not affect growth. Thin-layer chromatography analysis revealed that this strain could degrade agar into a monosaccharide and oligosaccharide, which may have industrial applications.
