The maintenance of adequate folate levels in the umbilical cord blood is esential for supplying tissue requirements of fetal growth. However, there is data on folate levels in the cord blood of Korean infant. The present investigation was undertaken to determine folate levels in cord blood and aassess relationships between folate levels and pregnancy outcomes. Dietary and supplementary folate intake was obtained from thirty subjects who were in the third trimester fo pregancy . The umbilical cord blood was drawn at delivery and pregnancy outcomes for the subjects were collected from their medical records. Erythrocyte and plasma folate levels in the cord blood were analyzed. The subjects were divided into two groups ; high folate (HF, $\geq$654ng/ml) and low folate (LF, <654ng/ml) groups according to erythrocyte folate levels in cord blood. Dietary folate intake and the amount of supplemental folates were not significantly different between the two experimental groups. However, infant birth weight (3540$\pm$295g) and placental weight(910$\pm$85g) for the HF group were significantly higher(p=0.0041 and p=0.109, respectively) than those for the LF group, which were 3127 $\pm$419g and 823$\pm$80g , respectively. Although it was not significant, the gestational weight gain for the HF group was 2.8kg higher than that for the LF group. Thus, the erythrocyte folate level in the cord blood was significantly related to infant birth weight and placental weight. These results confirm that a high erythrocyte folate level in the umbilical cord blood promotes both fetal and placental growth and improves gestational weight gain as well.

Reduced fetal growth is independently associated with increased risk of health problems in later life, particularly type 2 diabetes and cardiovascular diseases. Insulin resistance appears to be a key component underlying these metabolic complications. It is suggested that detrimental fetal environment may program insulin resistance syndrome. An insulin-resistant genotype may also result in both low birth weight and insulin resistance syndrome, and it is likely that the association of low birth weight with insulin resistance is the result of both genetic and environmental factors. Early postnatal rapid catch-up growth is closely related to risk for subsequent metabolic diseases. Fat mass is strikingly reduced in neonates born small for gestational age (SGA), and recent data suggest that insulin resistance seen in catch-up growth is related to the disproportionate catch-up in fat mass compared with lean mass. Endocrine disturbances are also recognized in SGA children, but overt clinical problems are infrequent in childhood. Cognitive impairment is reported in some children born SGA, especially those who do not show catch-up growth, in whom early neurodevelopmental evaluation is required. Breast feeding, also known to be protective against the long-term risk of obesity, may prevent some intellectual impairment in SGA children. Calorie-dense feeding does not seem to be appropriate in SGA infants. We must balance the positive effect of nutrition on neural development against rapid fat deposition and the future risk of insulin resistance.

One hundred two high-risk women(HRW) and 115 low-risk women(LRW) were studied at post-partal hospitalization and at 1, 4, and 8 months after giving birth to determine whether they would differ in the achievement of perceived maternal acquisition and whether predictors of maternal acquisition would differ for the two groups over time. The subjects were 102 HRW and 115 LRW, all in the above 27 weeks, admitted to two hospitals and to two clinic in the Kyoungnam area between July 1, 1998 and May 4, 1999. The data were analyzed by a SPSS program and the results are as follows ; 1) Predictors of Maternal role acquisition in the HRW were fetal attachment, maternal attachment, state anxiety, relationships of partner, social support in the early postpartum, maternal attachment, relationships of partner, depression, infant's health status in the postpartal 1 month, relationships of partner, self-esteem, educational degree in the postpartal 4 month, and maternal attachment, social supports in the postpartal 8 month. 2) Predictors of Maternal role acquisition in the LRW were fetal attachment, social supports, perceived experience about labor and delivery in the early postpartum, maternal attachment, sense of mastery in the postpartal 1 month, sense of mastery, experience with infants, relationships of partner in the postpartal 4 month and maternal attachment, experience with infants, social supports in the postpartal 8 month. 3) The hypothesis that HRW would score significantly lower on maternal competency than LRW was rejected. 4) The hypothesis that maternal acquisition would be significantly related to maternal attachment was accepted.

The objective of this study is to assess the effect of interpregnancy interval on fetal outcome among women with term premature rupture of membrane in public hospitals, Ethiopia, 2017. Facility based follow up study was conducted in Southern Ethiopia public hospitals from February 30, 2017 to August 20, 2017. Among 150 observed mothers with interpregnancy interval of less two years, 46.67 % (95% CI: (7.170, 29.93) of them experienced adverse birth outcome, but among 173 women with interpregnancy interval of two and above years, 5.78% (95% CI: (7.170, 29.93) of them experienced adverse birth outcome. The odds of adverse birth outcome were more among women with interpregnancy interval of less than two years (AOR=17.899, 95%CI: [6.425, 49.859]. The effect of interbirth interval of less than two years on adverse birth outcome of newborn was increased by length labor of >=24 hours, induction of labour and cesarean section delivery. Interpregnancy interval of less than two years, in collaboration with other risk factors, is the main predictor of adverse birth outcome. Therefore especial attention should be given to mothers with birth spacing by using family planning methods to reduce adverse birth outcome.

착상전기(着床前期}의 태아(胎兒)는 방사선(放射線)을 비롯한 많은 환경요인(環境要因)에 대하여 감수성(感受性)이 높은 개체(個體)임에도 불구하고 특히 이 시기는 임신부(姙娠婦)가 자각(自覺)적으로 임신을 감지할 수 없는 시기이기에 이러한 여러 환경유해요인으로부터 의도적으로 피할 수가 없다. 그러므로 착상전기의 영향을 충분히 검토한 후에 의료행위를 취할 것이며 이에 대한 방어(防禦)대책도 검토할 필요가 있다. 종래 까지 방사선에 대한 태아영향에 관한 많은 연구결과에 의하면 방사선 및 그 외의 유해요인에 대한 착상전기의 영향은 배사망(胚死亡)(유산(流産))만이 일어나며 기형(奇形)은 유발(誘發)하지 않는다고 하여 발생학(發生學)등 여러 교과서에서 기형은 기관형성기(器官形戚期)만이 국한(局限)해서 일어나는 영향이라고 단정되어 왔었다. 그러나 이 연구결과 착상전기에 있어서도 기형이 유발하여 오히려 기관형성기((器官形成期)보다도 감수성이 높다는 것이다. 또한 착상전기에서도 기형유발의 시기특이성을 가지며 여러 종류의 기형이 발생한다는 것이 본 연구로부터 밝혀졌다. 실험동물은 ICR Mouse를 사용했다. ICR Mouse는 일반적으로 태아사망 및 기형실험에 널리 사용되는 것이다. 사육조건은 Conventional 한 조건하에서 사육했으며 Mating 방법(方法)은 Female 마우스의 발정기(Sexual Excitement period)에 있는 mouse 질(膣)을 육안 적으로 관찰하여 $AM 6:00{\sim}AM 9:00$시까지 3시간만 mate시켰다. AM9:00시에 Vaginal Plug를 관찰하여 임신을 확인했다. Plug가 확인 된 마우스는 AM8:00시에 수정(Conception)된 것으로 가정하고 이 시점을 임신 0일 0시로 수정 난의 태아연령을 산정했다. 방사선조사는 $^{135}Cs\;{\gamma}-$선을 사용하였으며 임신 마우스의 전신조사를 실시하고 조사한 시기는 각 2, 48, 72, 96hpc이며 조사한 방사선 선량 군은 $0.1{\sim}2.5Gy$이다. 태아영향 관찰지표는 태아 연령은 mate일 오전 8:00시를 임신 0일 0시로 환산하여 태아연령 18일에 임신마우스를 Cervical vertebral dislocation에 의해 도살했다. 도살 후 해부하여 각 임신 마우스별로 관찰했다. 착상 율을 관찰하기 위하여 황체수를 세었고, 태아사망과 생존태아를 구별했다. 자궁 내 사망의 분류는 태아사망을 1) preimplantation death 2) Embryonic death 3) Fetal death로 분류했다. 착상전사망은 수정후 $0{\sim}4.5$일(1세포기${\sim}$배반포후기 부화까지)까지의 사망으로써 난소의 황체수(배란 수)와 착상태아(생존태아, 착상흔, 태반유잔, 흡수태아, 침연태아의 합계)로부터 구할 수 있다. Embonic death는 수정 후 $4.5{\sim}13$일까지의 사망으로써 Implantation sites, Placental remnants, Resorption of fetus로 관찰된 것이다. Fetal death는 수정후 $14{\sim}18$일까지의 사망으로써 Maceration of fetus로 관찰되는 것이다. 통계학적 분석은 각 Group의 착상 을과 자궁 내 사망 율을 산출할 때에는 각 임신마우스에 따라 발생빈도가 크게 다르기 때문에 통계처리에는 Non parametric 검정인 Kluskal Wallis 검정을 사용하여 분석하였다. 또한 개체 Level 영향인 착상을, 태아사망, 기형의 threshold dose의 산정에 대해서는 SAS-Logistic 검정에 따라 통계 분석을 하여 $5%(Ld_5,\;ED_5)$ 및 $10%{\times}2/3$점을 threshold dose로 판단했다. 태아체 중에 대해서는 parametric검정인 t-test검정에 의하여 분석했다. 그 결과 착상전기에서도 기형이 유발하며 특히 시기에 따라 일어나는 때와 일어나지 않는 때가 있음을 본 연구로부터 밝혀졌다. 또한 착상전기의 영향으로써 유발되는 기형은 여러 종류의 기형이 발생함이 밝혀졌다. 특히 이시기는 착상전 사망 및 배(胚)사망은 방사선 선량에 따라 크게 일어나나 태아사망(Fetal death) 및 태아체중은 유의차(有意差)가 없었다.

This study aims to find factors that affect variations in cesarean section frequency rates among OBGY clinics in Metropolitan areas. The factors include patient, medical supplier characteristics and economic factors. This study is a cross-sectional analysis using health insurance delivery claims from July to December 2000 and files of the NHIC(national health insurance corporation). Multiple regression was used to analyze the dependent variable of cesarean section frequency rate at each clinic. The results are as follows : Cesarean section frequency rate is increasing in proportion to the number of the following patients : repeated caesarean section, disproportion, obstructed labour, fetal distress, emergency caesarean section and self-employed patients. There are geographic variations as well. Cesarean section frequency rates are higher in Inchon and Gyonggi province than in Seoul. The higher number of total delivery the clinic has, the lower rate of cesarean section it has. Clinics with high frequency rates in 1999 showed higher rates the next year. Further research is required to develop evidence based delivery modes and change strategies for increasing normal delivery and activating midwife clinics.

About smoking and health control by theorize of common with various records investigation prevent an injury from smoking Further, should be contribute for the national health improvement for application of guide to health education. The results of investigation are as follows; 1) Tobacco be transmitted the first year of KwangHea's(reign) from GeeRu(the year of GeeRu), before sixth year of KwangHea's GapIn. 2) By reason of smoking an extreme poison ingerdients is Nicotine, Co, Tar etc three kinds. 3) The number of chemicalcompound in the tobacco smoking. Nicotine play an important part of it makes continue to smoking act. 4) Co, Not only injury vascular in the cell wall but also influence in ardiac muscular tissue. 5) Tar, is play an important part tl determine taste of tobacco or fragrace(a sweet smell). 6) Be demaged in the body with harmful objects of tobacco is first lung cancer, next heart disease, and chronic lung disease etc. 7) Passive smoke(indirect smoke)is first smoker's when have smoking and blow smoke from cigarette take smoking. On second when take smoking as it is burning cagar to end. 8) Female smoker are no good and bring many trouble to the mother's body and fetal body(an unborn child). 9) Nicotine also, like drug and alcohol break out reliance, introspection, poisonous or obstinence syndrome 10) A counterplan about smoke should be settlement with propriety control of smoking and an antismoking(non-smoker).

Purpose: Maternal Fetal Intensive Care Unit (MFICU), which provides intensive care to high-risk mothers with increasing maternal age and high-risk newborns, has become a new field of nursing work in South Korea. The present study was conducted to identify the educational needs and self-assessing clinical competence of nurses in MFICU. Methods: The education needs and competencies of MFICU nurses were measured through prepared questionnaires by researchers based on the previous studies on job analysis of nurses in MFICU. Data were collected from January 2019 to March 2019. The study involved 168 nurses working in MFICUs at 12 hospitals nationwide as study subjects. The data were analyzed using the SPSS WIN 23.0 program. Results: The education needs of nurses in MFICU had an average of 4.21 points (${\pm}0.50$) and their nursing competence was average 3.38 points (${\pm}0.60$). The items reported as high education needs but low competency by nurses in MFICU were as following: 'postpartum hemorrhage and shock,' 'cardiopulmonary resuscitation (CPR) for neonate,' 'CPR during pregnancy,' 'disseminated intravascular coagulation,' 'sepsis,' and 'mechanical ventilation during pregnancy.' Conclusion: Based on these results, it is proposed that a comprehensive education program for nurses in MFICU should be developed by considering low capabilities among MFICU nurses as a priority factor.

Purpose: Although insulin is usually injected into the abdominal subcutaneous fat, in pregnancy women tend to avoid abdominal injections due to concern about fetal damage. Prior studies have been limited to only measuring skin-subcutaneous fat thickness (S-ScFT) at one site at specific pregnancy points. This study aimed to measure S-ScFT across several abdominal sites and over the gestational period in Korean pregnant women. This can identify which site would be relatively safe for subcutaneous injection during pregnancy. Methods: Healthy women over 24 weeks of pregnancy in Korea were invited to voluntarily participate in this descriptive study. For the 142 women, S-ScFT of 12 sites in the abdomen were measured by ultrasound, several times over the pregnancy. Each incidence was treated as a case and a total of 262 cases were analyzed. Results: The mean S-ScFT during pregnancy was 1.14±0.47 cm (1.25±0.54 cm at 24⁺⁰-27⁺⁶ weeks; 1.17±0.48 cm at 28⁺⁰-31⁺⁶ weeks; 1.09+0.40 cm at 32⁺⁰-35⁺⁶ weeks; and 1.06±0.47 cm at 36⁺⁰-40 weeks of pregnancy). Most S-ScFT were thicker than 10 mm. But S-ScFTs in the lateral abdomen and some sites were suboptimal (<6 mm), especially in the pre-pregnancy underweight body mass index group, who had a high rate of suboptimal thickness (27.1% overall and 33.9% in the lateral side). Conclusion: The whole abdomen seems to be appropriate for subcutaneous injection in most Korean women during pregnancy, with a 4 to 5-mm short needle. However, for the lateral abdomen, making the skin fold might be needed for fetal safety.
