Six mature purebred Angus cows ($3.5{\pm}1.5$ years of age, $631.36{\pm}8.63kg$), three pregnant ($250{\pm}7$ days pregnant) and three non-pregnant and eight mature Suffolk ewes ($5{\pm}1.2$ years of age, $68.18{\pm}2.3kg$) four pregnant $115{\pm}5$ days pregnant) and four nonpregnant were utilized in a five-day metabolic trial to determine the effects of gestational status (pregnant vs. non-pregnant) on apparent absorption and retention of copper (Cu) and zinc (Zn). Animals were selected based on body weight, age, and gestational status, and randomly assigned to metabolic crates for total fecal and urine collection. Animals were allowed to acclimate to their new environment for seven days. Pregnant and non-pregnant cows and ewes were then paired (within a species) by body weight and pair-fed throughout the 5 day collection period. Copper and Zn intakes were similar for pregnant and non-pregnant animals within a species. Apparent absorption of Cu (p<0.06) and Zn (p<0.04) were higher in pregnant cows relative to non-pregnant cows. Pregnant cows also had a higher apparent retention of Cu (p<0.05) and Zn (p<0.06) relative to non-pregnant cows. Pregnant ewes had a higher (p<0.01) apparent absorption and retention of Zn compared to non-pregnant ewes. However, apparent absorption and retention of Cu were similar for pregnant and non-pregnant ewes. These data indicate that certain physiological and/or metabolic parameters are altered in pregnant cows and ewes consuming an alfalfa-based diet that enhance the apparent absorption and retention of certain trace minerals.

Gestational diabetes mellitus (GDM) is a common complication during pregnancy and one of the main causes of adverse fetal-maternal outcomes. However, the pathogenesis of GDM has not been clearly stated. Adiponectin, an adipose tissue-derived plasma protein, is involved in regulation of insulin resistance and glucose hemostasis, and thus is a key modulator of insulin action and glucose metabolism. In this study, we investigated to compare serum adiponectin levels in pregnant women with diabetes, pregnant women who are without diabetes, and non-pregnant women, and to evaluate relationship between serum adiponectin. levels and metabolic parameters. Forty-one pregnant women with diabetes, fifty-nine pregnant women without diabetes and forty non-pregnancy women were recruited. Adiponectin levels were significantly lower in pregnant women with diabetes when compared to non-pregnant women and pregnant women without diabetes. Pregnant women without diabetes at second trimester had lower adiponectin levels compared to non-pregnant women. Adiponectin was negatively correlated with BMI, fasting insulin, HOMA-IR, total cholesterol, and triglyceride. In conclusion, this study confirmed that the decreased level of adiponectin precedes the onset of abnormal glucose level during pregnancy and also normal pregnant women had lower adiponectin levels compared to non-pregnant women. This knowledge may help to identify strategies for lowering the occurrence of GDM in women who are at high risk of developing the disorder.

Plasma concentrations of zinc and copper were measured in 59 non-pregnant women and 105 pregnant women(12 ; early pregant, 93 ; late pregnant) to estimate and compare both groups and to detect the effects of iron supplementation on the plasma zinc and copper concentrations in the pregant women. The mean plasma zinc concentration of the early pregnant group was not significantly different with those of the non-pregnant group. But in contrast, the mean plasma zinc concentration of the late pregnant group was significantly lower than those of the non-pregnant and early pregnant group. Mean plasma copper concentration were significantly elevated in ealry pregnant group and doubled in late pregnant compared to non-pregnant. In Fe supplemented group, mean plasma zinc concentrations were lower and mean plasma copper higher than those of Fe non-supplemented group. It appeared that Fe supplementation had effects on the decrease of plasma zinc concentrations in pregnancy.

Purpose: This study aimed to identify the status of emergency care of pregnant women transported by paramedics, to analyze the knowledge of paramedics related to pregnant women and their self-confidence in emergency care, and to provide foundational data to improve the quality of emergency care for pregnant women. Methods: We received a total of 1,798 rescue logs from 119 paramedics, who had transported pregnant women, in I city from January 1, 2016 to December 31, 2018. For survey analysis, we used the 164 questionnaires received from these paramedics from June 15 to August 14, 2019. Results: The analysis of the rescue logs revealed that 85.5% (1,537 individuals) either had disease symptoms or were pregnant, whereas only 14.5% (261 individuals) had traffic accidents or accident-related injuries. The mean knowledge of the paramedics related to pregnant women was 23.73 (±2.98) points, and the mean self-confidence in emergency care was 3.19 (±0.74) points. Knowledge of the paramedics about pregnant women and their self-confidence in emergency care of these women had a statistically significant positive correlation (r=.306, p=.000). Conclusion: Paramedics should be provided theoretical and practical training through various programs about the emergency care of pregnant women.

Objective: The aim of this study was to compare the rate of maturation, fertilization, and embryo development of in vitro-matured human oocytes derived from pregnant and non-pregnant women. Methods: Immature oocytes were obtained by needle aspiration from 49 pregnant women (group 1) who underwent a cesarean section at term and 77 non-pregnant women (group 2) who underwent a gynecological operation during the same period (8 months). Healthy immature oocytes (530 in group 1 and 539 in group 2) were cultured and assessed for maturation 36 hours later. Mature oocytes were inseminated by intracytoplasmic sperm injection and cultured up to 144 hours. Results: The percentage of degenerated oocytes was significantly higher (12.1% vs. 6.3%; p<0.001) in group 1 than in group 2. There was no significant difference in the maturation rate (66.8% vs. 68.1%; p=0.698), fertilization rate (66.7% vs. 67.6%; p=0.857), or the rate of formation of good-quality blastocysts (46.2% vs. 47.2%; p=0.898) in oocytes obtained from pregnant and non-pregnant women. Conclusion: The developmental competence of immature oocytes did not differ between pregnant and non-pregnant women.

The purpose of this study was to estimate the mineral intakes and serum mineral levels of pregnant and lactating women. The subjects consisted of 34 non-pregnant, 56 pregnant and 20 lactating women. Nutrients intakes were investigated by the 24-hr recall method, and serum major and trace minerals were analyzed by the ICP-spectrometry. Calcium (Ca) and zinc (Zn) intakes were observed lower than RDA especially for both pregnant and lactating women. Iron (Fe) intake of pregnant women was $85 - 139\%$ RDA through Fe supplementation, and that of lactating women was lower than RDA. Compared with non-pregnant women, the pregnant women had similar Ca intake and higher magnesium (Mg) intake. Comparing with the non-pregnant women, serum Ca level in pregnancy was lower, and that of lactating women was not significantly different. Serum phosphorus and Mg levels were not significantly different among the groups. Serum Fe level of pregnant and lactating women was lower than that of the non-pregnant women. Serum Zn level of pregnant women was lower than those in the lactating and non-pregnant women. Serum copper level decreased as the pregnancy progressed. Serum sodium (Na) level was higher in 2nd- and 3rd trimester and potassium (K) level was higher in 3rd trimester and lactating period than other groups. Na/K ratio was not significantly different among the groups. During all periods, there was no correlation between dietary intakes and serum levels in each minerals. Serum Ca level positively corrleated with serum Mg level, especially in 3rd trimester and lactating women. In general, serum mineral levels in pregnancy were changed compared to the levels in non-pregnancy and restored in lactation to the levels for non-pregnancy.

Purpose: The aim of this study was to assess health-related behavior of pregnant women and breastfeeding mothers by investigating relevant risk factors. Methods: Data of 10,396 women (age 19 to 49 years) from the Korea National Health and Nutrition Examination Survey report from 2007 to 2012 was used to analyze factors associated with health-related behavior. The subjects were divided into pregnant women; breastfeeding mothers; and non-pregnant women. Bottle feeding mothers were excluded. Results: Current smoking rate including self-reported smoker and/or positive cotinine urine test were lower for pregnant or breast-feeding group than non-pregnant group. Heavy-drinking was not different among groups while monthly drinking rate was higher in non-pregnant group. Rate of stress recognition was lower in pregnant and breast-feeding group than non-pregnant group. Rate of experience for depressive symptoms and rate of suicidal ideation were not different among groups. Conclusion: Pregnant women and breast-feeding mothers maintain a good pattern of health- related behavior compared to non-pregnant women. However, substantial proportion of pregnant women and breast-feeding mothers continue to drink and smoke. This shows the need for a plan that will modify health-related behavior.

Purpose and Methods: Currently, Korea has the lowest fertility rate among OECD countries. It is also true that from the aspect of encouraging childbirth policy, as the use of automobiles has increased, the interest in securing parking spaces has also become more important. However, there are efforts and researches on the supplying parking spaces for the general public in society not to the positive discrimination such as elders or pregnant women. On the other hand, there is a growing need for a dedicated parking space for pregnant women due to the changing social environment and increasing number of female drivers. At this point, proper design of the maternity parking spaces is essential. Therefore, this study is analyzing the characteristics of pregnant women such as measurements and certain actions and case studies of domestic and oversea. Through the analysis of these factors, the following results were derived. Results: First, it was determined that the important factor in the planning of the parking-block for pregnant women was the human body size of pregnant women. And the required dimensions of movement of pregnant women were derived. Second, the dimensions of automobile were analyzed and applied from the most used vehicles in the family composition. Third, after the observations, the status of the parking spaces of the pregnant women and observations showed that the drivers not only the pregnant women but others were using the spaces improperly. Fourth, at certain conditions of the parking spaces, in order to improve the efficiency of the parking spaces, it is necessarily considered that the usage of designated accessible parking spaces can be used together by not only the disabled but also to the passengers who are classified as 'transportation weak' such as pregnant women. Implications: In this study, the researcher will propose the shape and size of the parking-block for pregnant women considering the elements derived above.

Dietary folate intake and serum folate levels were measured in 26 pregnant, 25 lactating, and 17 non-pregnant, non-lactating women. Dietary folate comsumption was estimated by calculating folate intake based on the information obtained from food frequency quesionnaires and serum folate levels were determined microbiologically using Lactobacillus casei. The total folate (from food and supplements) intakes of pregnant and lactating women were 326.9ug and 407.9ug, which was significantly higher than that of the non-pregnant, non-lactating women(139.5ug). However, with regard to food folate intake, there were no differences among the three groups (160ug for pregnant women, 143.4ug for lactating women). Forty-two percent and 36% of the pregnant and lactating subjects, respectively, were found to be taking commercially available nutritional supplements containing folate. The concentrations of folate in these supplements were in the range of 83ug~1, 000ug per tablet. For lactating women, serum folate levels were significantly higher when folate supplements were voluntarily used. The amount of folate intake was positively correlated with the serum folate levels in pregnant women, but not in lactaing women and non-pregnant, non-lactating women. Serum folate levels were negatively correlated with the ages of the pregnant women, and for lactating women, serum folate was positively correlated with their body weights.

This survey was carried out to investigate the nutritional status of 102 rural pregnant women after the 2nd trimester and the effect of pregnant nutritional status on newborn infant's anthropometric measurements. 102 rural pregant women's age was distributed 20 to 34. Pregnant height and prepregnant weight were 157.7$\pm$3.2cm and 50.7$\pm$5.4kg, respectively, which were similar to Korean standard, and pregnant weight gain per week after the 2nd trimester was 0.35$\pm$0.13kg, which was showed normal weight gain. Pregnant blood pressure were 112.6$\pm$12.7mmHg (systolic pressure) and 71.8$\pm$10.6(diastolic pressure), and energy and protein intake were 83.8$\pm$34.3% and 72.2$\pm$24.2% of RDA, respectively. Hemoglobin and blood protein level of 17 pregnant women who selected among total pregnant women were 11.8$\pm$1.0g / dl, 6.5$\pm$0.9g / dl, respectively. Height, weight, and head circumference of 17 newborn infants who delivered from 17 pregnant women were 50.1$\pm$1.9cm, 3.4$\pm$0.6kg, and 31.4$\pm$1.2cm, respectively, which were similar to Korean standard. Infant height, weight, and head circumference at birth were significantly correlated with pregnant higher than dietary intakes and weight gain per week during midpregnancy.
