Although iron is an essential mineral, excess iron intake during pregnancy may increase oxidative stress in tissues. This study was conducted to investigate the effects of iron overload during pregnancy on iron status and oxidative stress in maternal rats. Ten week-old female Sprague-Dawley rats were mated with male rats. Non-pregnant (control) and pregnant rats were fed diets containing normal Fe (35 mg/kg diet), high Fe (350 mg/kg diet), or excess Fe (1,050 mg/kg diet) during pregnancy. Rats were sacrificed on pregnancy day 19. No significant difference in weight gain, diet intake, or litter size was observed according to iron intake levels. Furthermore, serum iron, hemoglobin, and hematocrit were not different among the rats administered the three levels of Fe both in the control and pregnant groups. However, the iron levels were lower in pregnant rats than those in the control. The liver and spleen iron contents increased significantly in the excess Fe group. An increase in liver ferritin levels with increasing iron intake was observed. Protein carbonyl content, as a marker of oxidative stress, increased significantly in liver with increasing iron intake but not malondialdehyde. Glutathione peroxidase activity in the liver of pregnant rats fed excess iron decreased significantly. Bcl-2 protein expression in the liver declined remarkably with increasing maternal iron intake in pregnant rats. Taken together, iron overload during pregnancy had little effect on hematology. However, the deposits of iron in the liver and the decline in antioxidant enzyme activity implied increased oxidative stress in tissues of the excess Fe group. These results suggest that excess iron intake during pregnancy increases oxidative stress in maternal tissues and may also affect fetal tissues.

한우의 번식에 있어서 번식효율을 증진하기 위해서는 정확한 수정적기의 선택과 수정 후 가능하면 조기에 임신감정을 실시하여 공태기간을 최소로 단축시켜 번식우의 효율을 증진하고 송아지 생산비를 줄여야 할 것이다. 임신감정은 일반적으로 인공수정사나 수의사가 직장검사를 통해 태아를 확인하는 방법이 있으나, 이 방법은 수정 후 50-60일 이후부터 가능하며 숙련자에 따라 진단율이 다르며 암소에게 스트레스를 주고 태아나 난소에 손상을 주거나 심하면 태아의 조기폐사 등의 부작용이 있으며 진단율도 2-3만원 정도 소요된다. 최근 임신진단을 현장에서 간단히 조기에 진단할 수 있는 새로운 방법이 개발되어 있어 소개하기로 한다.

This study is to identify the effects of pilates mat exercise on the body composition, lumbar muscle strength, low back pain and pregnancy stress in pregnant women. In order to carry out this study, nineteen pregnant women were divided into two groups: pilates mat exercise group (n=11) and control group (n=8). EXE group performed pilates mat exercise for 60 min per day, 2days/week for 12 weeks. Our results showed that there was no significant changes in total body water, body fat mass, BMI, body fat percent, and BMR, but the EXE group showed significant increase in skeletal muscle mass. Furthermore, EXE group was significantly increased in hip extension and lumbar extension ROM. Analysis of low back pain and pregnancy stress level showed no significant difference between group. In conclusion, our study suggest that pilates mat exercise can be safely applied to pregnant women by increasing the muscle mass of pregnant women and by showing a positive effect on the lumbar muscle strength.

In this study, HRV signals are analyzed to compare the autonomic nervous system activity of non-pregnant women and pregnant women. 99 disease-free pregnant women and 27 non-pregnant women from W Hospital participated in the study. The acquired HRV signals were used by the program to perform time domain analysis and frequency domain analysis. The measured values were statistically analyzed for differences between pregnancy periods through a one-way ANOVA. In the results, SDNN and RMSSD in time domain analysis had significantly higher results in early pregnancy and non-pregnant women compared to mid- and late pregnancy. In frequency domain analysis, LF and HF had significantly higher values for pregnancy and non-pregnancy compared to midand late-term, but there was no significant difference between VLF and LF/HF. his means that as pregnancy progresses, the ability to control autonomous nerves decreases in the middle and late stages of pregnancy and increases physical fatigue and mental fatigue. Therefore, the longer the pregnancy period, the more special care is needed to maintain mental and physical stability of pregnant women.

Purpose: We aimed to assess the mediating effect of fatigue on the relationship between pregnancy stress and depression during the third trimester of pregnancy. Methods: We surveyed 161 pregnant women at a hospital in Gyeonggi province in Korea from October to November, 2017. Data were analyzed by the SPSS WIN 22.0 program. Results: The mean scores of pregnancy stress, fatigue and depression were $2.09{\pm}.87$ with a range of 1~4, $2.31{\pm}0.84$ with a range of 1~4 and $0.85{\pm}0.81$ with a range of 0~3, respectively. Pregnancy stress was positively correlated with fatigue (r=.60, p<.001) and depression (r=.59, p<.001) and fatigue was positively correlated with depression (r=.48, p<.001). The mediating effect of fatigue on the relationship between pregnancy stress and depression (${\beta}=.21$, p=.010) was found. Conclusion: We found the mediating effect of fatigue on the relationship between pregnancy stress and depression. Thus, healthcare professionals should assess the pregnant woman's negative emotions in the early stage and facilitate their positive transition utilizing the assesment findings. For example, a development of interventions considering physical and psychological aspects for decreasing fatigue may improve the pregnant women's well-being during pregnancy and childbirth. In conclusion, the healthcare professionals should understand the potential problems during pregnancy and strive to enhance the positive process of pregnancy and growth of the baby.

Purpose: The objective of this study was to investigate the relationship between fatigue, sleep disturbance, and gestational stress in women during late stage of pregnancy. Methods: This study was conducted with 113 healthy pregnant women at gestational age greater than 27 weeks who were registered at community health centers and received prenatal care. A structured questionnaire regarding fatigue, sleep disturbance, and gestational stress was used. The data was analyzed using a t-test, an ANOVA, and Pearson correlation coefficients. Results: The subjects with unplanned pregnancies and irregular exercise patterns showed a higher level of fatigue than those with planned pregnancies and regular exercise patterns. Pregnant women with caffeine intake manifested higher levels of gestational stress and sleep disturbance than those without. The levels of sleep disturbance and gestational stress increased as the fatigue levels increased. The fatigue levels increased with increased levels of sleep disturbance. Conclusion: Planned pregnancy, regular exercise patterns, and caffeine intake were related with fatigue, sleep disturbance, and gestational stress in women during late stages of pregnancy. Fatigue, sleep disturbance, and gestational stress had close associations to each other. In the future, such results should guide development of nursing intervention programs for women in late stages of pregnancy.

The perceived stress of pregnant women is a potential contributor to adverse birth outcomes. Although the importance of the psychosocial well-being of pregnant women has been emphasized, there are fewreliable and valid instruments to measure the stress level of pregnant women in Korea. This study evaluated the psychometric properties of Ahn's pregnancy related stress scale (PSS) that was originally developed in 1984. Two hundred pregnant women completed the survey questionnaire, which was comprised of the PSS, depression scale, and demographic information. Principal component analysis and confirmatory factor analysis was used to test the construct validity. The concurrent validity was evaluated using the correlation with depression scores. Based on exploratory factor analysis and a consideration of conceptual meaning, a five-factor structure was extracted, explaining 57.25% of the variance: physical discomfort, fetus, parenting, spouse relationship, and housework. The goodness-of-fit indices showed an acceptable fit overall with the full model and acceptable internal consistency (Cronbach's alpha =.89). The concurrent validity was confirmed by a comparing with the depression score (r=.48, p <.001). The shortened PSS, as a valid and reliable scale, is recommended to be used to assess pregnancy-related stress and to develop stress managing interventions for pregnant women in clinical settings.

The objective of this study was to develop the stress coping program for pregnant adolescent to alleviate the stress levels and symptoms, and to cope with the stress adequately. The program of this study was based on the cognitive-behavioral theory and the stress management. The program was done twice a week totally 8 times and preview meeting was done 1 week before the program and follow-up was formed 4 weeks after finishing the program. one-group pretest-posttest design was held and the group was 13. In case of qualitative research, the content of discussion in the course of group process, investigation, and the materials which were made from the group members were classified and analysed to the objects of program. first, the common change of members was reduction of stress levels by attending stress management program. Second, the coping skills for stress were verified and improved. More than one new coping skills were acquired such as positive re-evaluation, persuasion, self-talk, I-message communication method, assertive self-expression, and problem settlement. Third, the group members admitted their irrational beliefs and partially had a change of it. The implications for the future practice are discussed.
