This research is to study about the weight-change of a pregnant woman, conditions of the woman and an infant. The weight-change of a mother during pregnancy was observed and that was expressed as the basis on the body mass index of a mother before pregnancy. The effects of weight-changes on both the discomfort, complications of pregnant mother and the condition of an infant were also investigated. Thus we set a purpose that this study would help pregnant woman and an infant to maintain and enhance their health conditions by proper weight control through nursing mediation. This study was performed in a certain hospital of university in seoul from Feb. 1. 2000 to Mar. 31. 2000. We explained the purpose of this study to the hospital institution and obtained consent of investigation. 152 inpatients who were in condition from PA 37 weeks to PA 42 weeks were the subject of this study. The research materials were made through of question paper that inpatients make answer by themselves and investigation paper. The question paper was about general background, weight and height before pregnancy and discomfort of the physical degree. And the investigation paper was about parity, maternal weight(late pregnancy), high pregnancy, delivery method, hemoglobin level, Apgar score, fetal weight. Physical discomfort was measured using the implement made by Kim hae won(1996) (chronbach's ${\alpha}=0.85$). SPSS was used to do statistics for managing and analyzing data. The results of this study were like followings. 1. The mean value of gained weight during pregnancy was about 13.8kg within from 3 kg to 26 kg. Among 152 research candidates, the gained weight of 80(52.6%) candidates remained within an ideal range. But that of 37 candidates(24.3%) became less than the ideal range. Also that of 35 candidates(23.0%) became over than the ideal range. 2. In the investigation of the relation between the weight change of a pregnant woman and her condition, the scores to represent physical discomfort were middle in all candidates. And the physical discomfort of over weight-gained group was more than that of low weight-gained group, but there was no difference in statistics(F=0.234, p=0.791). The weight-changes of pregnant woman didn't have an influence with the high risk of pregnancy(F=0.509, p=0.477). Also, the weight-changes didn't have an influence on delivery method($x^2=3.825$, p=0.148). However, in the investigation of the relation between weight-change and hemoglobin level, the change of hemoglobin level was highest in over weight gained group(F=3.062, p=0.05). 3. In the investigation of the weight-change of pregnant woman and the condition of infant. the weight changes didn't have an influence on both 1 min Apgar score(F=0.157, p=0.855) and 5 min Apgar score(F=0.030, p=0.970) of infant. Also, in the investigation of weight-change of a pregnant woman and weight difference of a infant with Pearson Correlation Coefficient, the weight-change of a pregnant woman affected vastly the weight of a infant. It was also found that the more pregnant woman gained in weight, the more did gain weighty infants. This relation was in net proportion(r=0.256, p=0.001). In conclusion, these results suggest that the weight-changes during pregnancy in Korea women of these days are more increased than that of the past days and individual variation in weight-changes is very high. Also, these results suggest that the changed hemoglobin level of a mother and weight of an infant were meaningfully affected by the weight-changes of a pregnant woman during pregnancy. However, the physical discomfort of a pregnant woman, the high risks of pregnancy, the delivery method and Apgar score of an infant were not affected by the weight-changes during pregnancy. Because the recommendation suggesting the ideal weight-change, used this study, is basis on the subject of American women, therefore, these results also suggest the necessity of such recommendation which is subject to Korean women.

Background: This study aimed to better understand the barriers to perinatal hepatitis B prevention and to identify the reasons for poor hepatitis B knowledge and delivery of education to hepatitis B surface-antigen-positive pregnant women among healthcare providers in Santa Clara County, California. Materials and Methods: Qualitative interviews were conducted with 16 obstetricians and 17 perinatal nurses in Santa Clara County, California, which has one of the largest populations in the United States at high risk for perinatal hepatitis B transmission. Results: Most providers displayed a lack of self-efficacy attributed to insufficient hepatitis B training and education. They felt discouraged from counseling and educating their patients because of a lack of resources and discouraging patient attitudes such as stigma and apathy. Providers called for institutional changes from the government, hospitals, and nonprofit organizations to improve care for patients with chronic hepatitis B. Conclusions: Early and continuing provider training, increased public awareness, and development of comprehensive resources and new programs may contribute to reducing the barriers for health care professionals to provide counseling and education to pregnant patients with chronic hepatitis B infection.

This study was carried out to assess the problems with the pregnant women, and check out the risk-factors in the high-risk pregnancies, using a simplified antepartum risk-scoring system, which was revised from Edwards' scoring system to be suitable for Korean situaition. This instrument was included 4 categories, demographic, obstetric, medical and miscellaneous factors. This survey was based on the 1300 pregnant women who were admitted, $x^2$-test, F-test, Pearsons correation, using statistical package SAS in NAS computer system, KIST. The results of the study were as follows; 1. 1313 infants were deliveried of these 560 infants(42.7%) were born to mothers with risk-scores > 7, and 753 infants(57.3%) were born to mothers risk-scores <7. 2. Maternal age" parity, education level, of the demographic factors were significant relation statistically to identify the high risk pregnancies($X^2$=20.88, 42.87, 15.60 P < 0.01). 3. C-section, post term, incompetent cervix, uterine anomaly, polyhydramnios, congenital anomaly, sensitized RH negative, abortion, preeclampsia, excessive size infant, premature, low birth weight infanl, abnormal presentation, perinatal loss, multiple pregnancy, of the obstetric factors were significant relation statistically to identify the high risk-pregnancies. ($X^2$ = 175.96, 87.5, 16.28, 21.78, 9.46, 8. 10, 6.75, 22.9, 64.84, 6.93, 361.43, 185.55, 78.65, 45.52, P < 0.01). 4. Abnormal nutrition, anemia, UTI, other medicalcondition(pulmonary disease, severe influenza), heart disease, V.D., of the miscellaneous and medical factors, were significant relation statistically to identify the high risk-pregnancies. 5. Premature, low birth weight infant, contracted pelvis, abnormal presentation, of the risk factors were significantly related with Apgar score at 1 '||'&'||' 5 minute after birth and neonatal body weight. 6. Apgar score at 1 '||'&'||' 5 minute after, birth and neonatal body weight were significantly negative correlated with risk-score. 7. There were statistically significant difference between risk-score and Apgar score at 1 '||'&'||' 5 minute after birth, 3 group(0-3, 4-6, above 7), and neonatal body weight, 2 group(below 2.5kg, the other group) (F=104.65, 96.61, 284.92, P<0.01). 8. Apgar score at 1 '||'&'||' 5 minute after birth(below 7), and neonatal body weight(below 2.5kg), were significant relation statistically with risk score.($x^2$=65.99, 60.88, 177.07, P<0.01) were 60.8 %, 60% . 9. Correct classifications of morbid infants(l '||'&'||' 5 minute Apgar score < 7) were 77.8%, 83.8% and that of nonmorbid infants(l '||'&'||' 5 minute Apgar score > 7) were 60.8%, 60%. 10. There were statistically significant difference between dislribution of maternal risk-score among the morbid infants(l '||'&'||' 5 minute Apgar score < 7) and non morbid infants(l '||'&'||' 5 minute Apgar score> 7) ($x^2$=64.8, 58.8, P < 0.001). 11. There were statistically significant difference between distribution of morbid infants(l '||'&'||' 5 minute Apgar score < 7) and fetal death. 12. The predictivity for classifying high.risk cases was 12 % and for classifying low-risk cases was 98.3 % in 5 minute Apgar score. Suggestions for further studies are as follows; 1. Contineous prospective studies, using this newly revised scoring system are strongly recommended in the stetric service. 2. Besides risk facto~s used in this study, assessmenl of risks by factors in another scoring system and paralled studies related to perinatal outcome are strongly recommended.

Purpose: Noninvasive prenatal test (NIPT) by massively parallel sequencing (MPS) of cell-free fetal DNA in maternal plasma marks a significant advancement in prenatal screening, minimizing the need for invasive testing of fetal chromosomal aneuploidies. Here, we report the initial clinical performance of NIPT in Korean pregnant women. Materials and Methods: MPS-based NIPT was performed on 910 cases; 5 mL blood samples were collected and sequenced in the Shenzhen BGI Genomic Laboratory to identify aneuploidies. The risk of fetal aneuploidy was determined by L-score and t-score, and classified as high or low. The NIPT results were validated by karyotyping for the high-risk cases and neonatal follow-up for low-risk cases. Results: NIPT was mainly requested for two clinical indications: abnormal biochemical serum-screening result (54.3%) and advanced maternal age (31.4%). Among 494 cases with abnormal biochemical serum-screening results, NIPT detected only 9 (1.8%) high-risk cases. Sixteen cases (1.8%) of 910 had a high risk for aneuploidy: 8 for trisomy 21, 2 for trisomy 18, 1 for trisomy 13, and 5 for sex chromosome abnormalities. Amniocentesis was performed for 7 of these cases (43.8%). In the karyotyping and neonatal data, no false positive or negative results were observed in our study. Conclusion: MPS-based NIPT detects fetal chromosomal aneuploidies with high accuracy. Introduction of NIPT as into clinical settings could prevent about 98% of unnecessary invasive diagnostic procedures.

각 의료기관에서 분만하는 산모와 신생아의 특성을 비교분석하고 의료기관별 산모와 신생아의 위험수준을 조사하여 특정 의료기관에서 관찰한 연구결과를 해석하는데 참고 자료를 제공하기 위하여 대구시내 3개 대학병원, 2개 종합병원,2개 개인의원, 1개 조산소, 그리고 1개 모자보건센터에서 1987년 4월 1일 부터 4월 30일 까지 1개월간(1개 대학병원은 2개월간) 분만한 산모 1,410명을 대상으로 산모의 연령, 교육수준, 의료비 지불방법, 산과력 및 특정의료기관을 선택한 이유를 면담 조사하고 병원기록지에서 신생아의 출생시 체중의 조사하였다. 대학병원과 종합병원을 이용한 산모의 평균 연령은 각각 27.5세, 26.7세로 조산소(25.4세)와 모자보건센터(26.1세)를 이용한 산모보다 많았고, 교육수준은 대학병원(평균 12.7년)과 종합병원(평균 12.2년) 산모가 조산소(평균 9.2년) 및 모자보건센터(평균 9.3년) 산모보다 월등히 높았다. 그리고 의료보험 대상자도 대학병원(78.1%)과 종합병원(82.9%) 산모가 개인의원(44.3%), 조산소(29.1%)나 모자보건센터(5.4%) 보다 많았다. 모자보건센터는 2번째 출산이 47.3%로 가장 많았으나 다른 의료기관은 모두 초산부가 $56.0{\sim}61.7%$로 제일 많았다. 산모의 산과력 비교에서는 대학병원 산모가 자연유산 경험율이 상대적으로 다른 의료기관 산모보다 높았고 사산 경험자도 소수였으나 조산소와 모자보건센터에서 분만한 산모는 사산 경험자가 1명도 없었다. 대학병원 산모의 경우 37주 이하의 조산아 출생율(11.4%)과 2,499gm이하의 저체중아 출생율($5.8{\sim}13.0%$)은 타 의료기관 보다 현저히 높았다. 이에 따라 제왕절개술에 의한 분만율은 의료기관간에 차이가 많았다. 결국 대구시내 대학병원과 종합병원에서 분만하는 산모들은 사회경제적으로 중, 상류층과 소득고하를 막론하고 고위험산모들이 많고 조산소와 모자보건센터는 저소득충의 산모 가운데 산과적으로 저위험군들이 많이 이용하고 있다. 따라서 특정 의료기관을 대상으로 조사한 자료를 해석하는데 많은 제한성이 있으며 전체 산모의 특성으로 일반화하는 것은 불가능한 것으로 생각된다.

Purpose: Influenza is the most common seasonal infectious disease that causes permanent social, economic, and medical problems worldwide. Therefore, the most effective way to prevent influenza is through vaccines. The aim of this study is to identify the influence of factors that determine the refusal of influenza vaccine among three subjects groups. Materials and Methods: A survey was conducted amongst the three high-risk groups in 2018-2019 (Moscow, Russia). The survey involved 1,620 parents and pregnant women (group 1), 324 doctors (group 2), and 433 students (group 3). Poor vaccine uptake was observed among respondents in all three groups. Results: According to the survey results, only 22.2% of children and 13.8% of adults were vaccinated against influenza. Group 2 showed increased rates with 36.7% of vaccinated adults and 58.7% of children. The lowest adherence to annual vaccinations was recorded in group 3 (only 17.3%). There is also a negative correlation between adherence to vaccination and smoking (-0.66), unhealthy diet (-0.73), poor oral hygiene (-0.61), and insufficient awareness of the need for influenza vaccine as well (-0.81). Conclusion: Thus, a general lack of vaccination awareness has a fundamental role in forming a negative attitude toward influenza vaccine. It is necessary to conduct research to promote vaccination against influenza to improve vaccine uptake among high-risk groups, particularly students.

Purpose: The aim of this study was to review the literature to determine whether intensive pelvic floor muscle training during pregnancy and after delivery could prevent urinary and fecal incontinence. Methods: Randomized controlled trials (RCT) of low-risk obstetric populations who had done Kegel exercise during pregnancy and after delivery met the inclusion criteria. Articles published between 1966 and 2012 from periodicals indexed in Ovid Medline, Embase, Scopus, KoreaMed, NDSL and other databases were selected, using the following keywords: 'Kegel, pelvic floor exercise'. The Cochrane's Risk of Bias was applied to assess the internal validity of the RCT. Fourteen selected studies were analyzed by meta-analysis using RevMan 5.1. Results: Fourteen RCTs with high methodological quality, involving 6,454 women were included. They indicated that Kegel exercise significantly reduced the development of urinary and fecal incontinence from pregnancy to postpartum. Also, there was low clinical heterogeneity. Conclusion: There is some evidence that for antenatal and postnatal women, Kegel exercise can prevent urinary and fecal incontinence. Therefore, a priority task is to develop standardized Kegel exercise programs for Korean pregnant and postpartum women and make efficient use of these programs.

임산부에게 약물을 사용하는 것은 태아에게 잠재적인 위협이 될 수 있으므로 임산부가 복용을 피해야 할 약물을 분류하는 것은 필수적이다. 하지만 많은 화합물이 태아에게 독성을 나타낼 수 있는지에 대한 근거가 불분명하며, 그것을 밝혀내기 위해서는 많은 시간과 비용이 투자된다. In silico 기반 가상 스크리닝은 광범위한 화합물에 대해서 적은 비용과 시간으로 어떤 화합물이 태아에게 높은 위험을 보일 수 있는지 예측하는데 활용될 수 있다. 우리는 한국과 호주 정부의 임신 중 약물 처방을 위한 위험 분류 리스트를 활용해 약물의 분류 등급 정보를 가져왔다. 약물의 구조적 특징과 화학적 특징을 기반으로 다양한 머신 러닝 기법을 적용하여 약물의 태아 독성 여부를 예측하는 모델을 생성하였으며, 정량적 성능 평가를 수행하였다. 나아가, attention 알고리즘을 활용하여 제안하는 모델이 약물의 태아 독성을 예측하는 과정에서 화합물의 어떤 하위 분자 구조가 중요하게 활용되었는지 확인하였다. 해당 연구를 통해 광범위한 화합물에 대해 높은 태아 독성 위험도를 가진 약물을 머신 러닝을 통해 예측할 수 있는 것을 확인하였다. 우리의 연구는 단순한 약물의 태아 독성 예측에서 나아가, 유의미한 하위 분자구조를 제공함으로써 연구자들이 약물의 태아 독성을 증명하기 위해 수행하는 실험에서 핵심적인 역할이 가능할 것이다.

최근 사회적으로 결혼연령이 높아짐에 따라 고령산모가 증가하면서 생화학적 표지물질을 이용한 다운증후군 선별검사는 산모들에게 필수적인 검사가 되었다. 다운증후군 임신을 진단하는 과정은 선별검사에서 고위험군으로 보고 되면 융모막 융모생검이나 양수검사 같은 침습적 검사를 통해 염색체 분석을 하는 단계로 진행이 되는데 이러한 확진검사는 비용이 많이 들고 태아손실의 위험도가 높다. 따라서 위험도는 낮고 다운증후군 발견율이 높은 선별검사를 선택하여 불필요한 침습적 검사를 줄여 산모와 태아의 위험도를 낮추는 것이 중요하다. 본 연구는 2018년 용인의 임상검사기관에 산전선별검사를 의뢰한 17세부터 46세까지 총 36,436명을 대상으로 triple test(185명), quad test(3,629명), integrated test(18,932명), sequential test(13,690명) 4가지 검사를 direct sandwich, indirect sandwich 기술을 이용한 Time-resolved fluoroimmunoassay 방법과 sandwich 방법을 이용한 면역측정 방법을 사용하여 35세 미만과 35세 이상 산모의 다운증후군 위험도를 분석하여 산모 연령이 증가함에 따른 양성률의 차이를 확인하였다. 검사결과 전체 산모의 다운증후군 고위험군은 triple test 36명, quad test 408명, integrated tset 1,441명, sequential test 924명 이었다. 이중 35세미만 산모의 고위험군은 triple test 7명(3.8%), quad test 141명(3.9%), integrated tset 644명(3.4%), sequential test 430명(3.4%)이었고, 35세이상 산모의 고위험군은 29명(15.7%), 267명(7.4%), 797명(4.2%), 494명(3.6%)으로 나타나 35세이상 산모가 훨씬 높은 고위험군을 나타내었다. 임상에 있어서 35세 미만과 35세 이상 산모의 위험도 분석을 한 연구는 국내외에 거의 희박하므로 본 연구는 향후 국내외의 많은 검사기관들과 예비 산모들에게 다운증후군 위험의 예방과 치료를 위한 매우 유용한 기초 자료가 될 것으로 생각된다.
