Elevated maternal plasma homocysteine concentrations have been associated with adverse pregnancy outcomes, including birth defects, low birth weight, preeclampsia, spontaneous abortion, placental abruption, and other maternal or fetal complications. The purpose of this study was to assess the maternal plasma homocysteine level during pregnancy and to investigate the relationship between the plasma homocysteine concentrations and pregnancy outcomes. Venous blood samples were drawn from 82 pregnant women who were grouped with gestational age, 1st trimester (n = 26), 2nd trimester (n = 27) and 3rd trimester (n = 29). The concentration of plasma homocysteine was analyzed by HPLC, and pregnancy outcomes including gestational length, maternal weight gain, infant birth weight, and Apgar score were collected with the medical records of the pregnant women. The levels of plasma homocysteine of the pregnant women at the 1st, 2nd, and 3rd trimester were 5.7 $$\pm$ 3.7\mu㏖/L,\;5.6 \pm4.1\mu㏖/L\; and\; 7.0\pm 4.5\mu㏖/L$, respectively, which had not showed any significant difference. The result of this study showed that in case of the pregnant women at the 1st trimester, the maternal plasma homocysteine level of the pregnant women whose gestational length was less than 38 weeks was significantly high (p < 0.01) compared to that of the pregnants whose gestational length was more than 38 weeks. And also, the level of homocysteine of the pregnant women at the 2nd trimester was significantly low when the maternal weight gain was high (p < 0.05). These findings suggest that maternal plasma homocysteine level at early stage of gestation will be a predicter of gestational length and maternal weight gain.

Purpose: This study tries to systematically understand factors that explain levels of happiness among pregnant women in the Ecological systems theory. Methods: A descriptive, cross-sectional study was conducted with 169 pregnant women in Korea. Collected data from self-report questionnaires were analyzed by hierarchical regression analysis using the SPSS statistics 23 program. Results: A total of 5 models were examined according to individual, microsystem, mesosystem, exosystem, and macrosystem in the Ecological systems theory. In the first model including individual factors, extraversion, neuroticism, and physical and psychological change constitute significant factors explaining happiness. In the second model with microsystem factors and in the third one with mesosystem factors, marital intimacy appears to be a significant factor. In the fourth model including exosystem factors, community service is a significant factor. In the final model with social atmosphere, personality (${\beta}=.15$ for extraversion; ${\beta}=-.30$ for neuroticism), physical and psychological change (${\beta}=-.15$), marital intimacy (${\beta}=.35$), and community service (${\beta}=.18$) turn out to be significant. These factors explain 59% of the variance of happiness in the pregnant women in Korea. Conclusion: Considering the fact that pregnant women's happiness is explained by microsystem and exosystem factors as well as individual factors, developing intervention programs that can promote influencing factors such as marital intimacy and community service is necessary to improve levels of happiness among pregnant women in Korea.

Pregnant women's psychological health affects the health of the fetus. Therefore, health care for pregnant women is essential for a healthy fetus. One of the symptoms of pregnancy among many pregnant women is the depression of emotional ups and downs. One way to relieve this depression is to use light therapy and color therapy by using lighting. Adjust the color temperature of the light so that it affects the emotions through color. For example, ceiling lights in car dealerships are set up like a sun-light, or low color temperature are used to create a comfortable mood in facilities like spas. In this paper, we use image sensors to identify the psychological state and change the color temperature of the lighting in real time. The study was conducted to relieve postpartum depression by using the psychological effects of pregnant women with easily purchased lighting devices.

Purpose: This study was conducted to investigate the safety of dental imaging in pregnant women with respect to fetal health. Materials and Methods: Searches were conducted of the PubMed, Scopus, and Web of Science databases in May 2023. The inclusion criteria encompassed cross-sectional and longitudinal studies that focused on the analysis of diagnostic dental imaging in pregnant women, as well as studies utilizing phantoms to simulate imaging examinations. The exclusion criteria consisted of reviews, letters to the editor, book chapters, and abstracts from scientific conferences and seminars. Results: A total of 3,913 articles were identified. Based on a review of the titles and abstracts, 3,892 articles were excluded, leaving 21 articles remaining for full-text review. Of these, 18 were excluded, and 4 additional articles were included as cross-references. Ultimately, 7 articles underwent quantitative-qualitative analysis. Three retrospective studies were focused on pregnant women who underwent dental imaging procedures. The remaining 4 studies utilized female phantoms to simulate imaging examinations and represent the radiation doses absorbed by the uterus or thyroid. Conclusion: Few dental radiology studies have been conducted to determine the safe radiation threshold for pregnant women. Additionally, the reviewed articles did not provide numbers of dental examinations, by type, corresponding to this dose. Dental imaging examinations of pregnant women should not be restricted if clinically indicated. Ultimately, practitioners must be able to justify the examination and should adhere to the "as low as diagnostically acceptable, being indication-oriented and patient-specific" (ALADAIP) principle of radioprotection.

BACKGROUND: To assess the interventricular septum (IVS) volume of fetuses from pre-gestational diabetes mellitus (DM) pregnant women by 3-dimensional ultrasound using spatiotemporal image correlation (STIC) and virtual organ computer-aided analysis (VOCAL) methods. METHODS: This was a prospective cross-sectional study of 45 fetuses from pre-gestational DM and 45 fetuses from healthy pregnant women (controls). Only singleton pregnancies between 20 and 34 + 6 weeks of gestation were included. The fetal IVS volumes were obtained off-line using STIC and VOCAL methods. To analyze differences among variables, the Student's t-test and Mann-Whitney U test were used. The correlation among continuous variables was determine using Spearman's correlation test (r). RESULTS: The median of fetal IVS volume was significantly higher in pre-gestational DM than in healthy pregnant women (0.3 cm³ vs. 0.2 cm³, p = 0.032). A strong positive correlation was observed between fetal IVS volume and gestational age at the time of ultrasound examination (r = 0.75, R² = 0.48, p < 0.0001) and between fetal IVS volume and estimated fetal weight (r = 0.63, R² = 0.37, p < 0.0001). No significant correlation was noted between fetal IVS volume and glycated hemoglobin levels (r = -0.16, R² = 0.01, p = 0.540) in the pre-gestational DM pregnant women. CONCLUSIONS: Significant differences were observed in fetal IVS volumes between pre-gestational and healthy mothers, with higher values in the fetuses of pre-gestational DM pregnant women.

Purpose: This study aims to compare protection against diphtheria and tetanus conferred on the mother and the neonate before and after maternal vaccination against tetanus, diphtheria, and acellular pertussis (Tdap), transfer of antibodies, and the variables that could impact on the protection. Materials and Methods: The study followed a cohort of 200 pregnant women from a region in Colombia, contacted during prenatal control before vaccination and upon delivery. The work determined immunoglobulin G antibodies against diphtheria and tetanus of pregnant women and umbilical cord. The proportion of protection, the geometric mean of the concentration, and the transfer of maternal antibodies were calculated. The protection profile of the pregnant women was explored by using multiple correspondence analysis. Results: The concentration of antibodies against diphtheria was significant before and after vaccination of the pregnant women (p=0.000) with proportions of 85.0% and 97.5%, respectively, and of 98.6% in the umbilical cord, with significant antibody correlation (Spearman's coefficient=0.668, p=0.01). Sero-protection against tetanus before vaccination was at 71.0%, after at 92.6%, and in the umbilical cord at 95.9%, with significant antibody concentration before and after vaccination (p=0.000) and antibody correlation (Spearman's coefficient=0.936, p=0.01). Sero-protection was higher when the pregnant women were vaccine 8 to 11 weeks before delivery. Unprotected pregnant women were those not vaccinated during pregnancy. Conclusion: The high proportion of protection against diphtheria and tetanus and the placental transfer support the need to promote maternal immunization with Tdap.

A survey was conducted from January 23 to 31 and February 14 to 18, 1981, in Whaseounggun, Kyunggj-do, to investigate the dietary and nutritionary status, and prevalence of parasitic infection of the fertile women, in an attempt to provide an integrative perspective on the rural family health programmes. The results are summarised as follows; The total number of fertile women, randomly selected, was 197 ; 21 women were in the latter half of pregnancy; 38 women, lactating, the remaning, non-pregnant. Average age of the subjects was 31.4 years; average number of children, 2.7; average number of abortion, 0.9; average family number in home, 5.5. The families had a mean income of \ 2,470,000 per fear. The majority, 83.8% of the families, were engaged in farming. 61.4% of the subjects had completed schooling 6 years or less. The mean energy intake of the lactating women was 73.4% of the recommended allowance, while that of non-pregnant and pregnant women reached 86.9 to 88.6% of the recommendation. In the average diet of the subjects, carbohydrates contribute 74.6 to 81.7% of the total energy intake; protein 11.3 to 11.9%; fat 7.0 to 13.9%. Protein intake of non-pregnant, pregnant, and lactating women met 72.6%, 60.8%, and 65.2% of allowance, respectively; and those proteins were mainly derived from vegetable sources. The subjects ingested less than one-half of the allowances for iron, calcium, vitamin A, and riboflabin ; in contrast, thiamin and ascorbic acid levels were adequate or fairly acceptable. There were significant correlations of meal balance and food diversity scores to the mean intake levels of protein, calcium, iron, vitamin A, thiamin, and riboflavin. Only 10% of the pregnant women and 11.4% of non-pregnant and lactating women reached the acceptable level of hemoglobin. Positive prevalence of parasitic infection was found among about one-third of the subjects, 30.3% of women. Hematologic findings had no significant correlation to parasitic infection.

By cluster sampling measurements, passing months of pregnancy according to changes of pregnant women body forms. On the basis of the above mentioned data, sizes of pregnant women clothes were decided. The results are as follows. 1. By cluster sampling measurements, sixty-nine items of apparel were obtained during the three different periods of pregnancy. They included the mean and standard deviation of body form measurement and the minimum and maximum values (Chart 3-4). The results of these surveys made it possible to notice the changes of pregnant womens' physical characteristics, i. e., the increased physical proportions: frontal waist area, umbilicus width, abdominal girth, crotch length, the length of the nipple, and body weight and the decreased proportions: omphalos height, perineum dimension. There was little change in the rear parts of the body. 2. The analized results of principle factors for body form measurements by cluster measurements produced seven major factors for which the proper values were over 1.0. They were: form factor, pregnancy factor, posture factor, breast formation factor, rear body formation factor, and nipple to nipple breadth. 3. In deciding garment sizes of pregnant women, four different sizes were established; small, medium, large, and extra-large according to the third, fifth, eighth, and tenth month of pregnancy. The measurement value of each item was produced by estimate.

This study develops leggings patterns for pregnant women with increased needs in utilization and necessity. It provides basic data for the development of leggings for pregnant women. The pattern was deformed by analyzing the leggings of U company, and simulated using the DC Suite Program. SPSS 24.0 was used for the analysis. As a result of the appearance evaluation, the primary pattern had many spaces in the thighs, calves, and the upper part; in addition, wrinkles occurred in the upper part and the knee part. The length of the leggings was long and agglomeration in the ankle appeared. Wrinkles were reduced by setting the hip circumference, hip width, and leggings length to reflect the results of the primary in the case of the secondary pattern. A pattern was developed that closely adhered to the body without any wrinkles in the appearance evaluation of the final pattern. Future studies should examine legging patterns of pregnant women according to the material change. Wearing evaluation and appearance evaluation should be done by making actual leggings for pregnant women, not 3D simulation.
