Purpose: An exploratory study was done to examine the validity of the new Ballard scale with extended scoring system(eNBS) in estimating gestational age(AG) in full-term newborns. Method: The eNBS scoring system was extended to include all numbers of total score of NBS and GA to allow a 3-days variation in GA estimatio compared to the original scale which has a 2-week variation due to the application of a 5-score interval for the total NBS score and only even numbers for GA. GA by eNBS(GA-eNBS) was compared with GA by LMP(GA-LMP) and GA by standard NBS(GA-sNBS) in 133 full-term newborns. Difference between GA-LMP and GA-eNBS was analyzed for each GA. Results: Positive correlations were observed in GA-sNBS and GA-eNBS with GA-LMP. There was no difference between GA-LMP and GA-eNBS at 39GA and 40GA. At 37GA and 38GA, GA-eNBS overestimated GA-LMP up to 1 week, while underestimating up to 1 week at 41GA. Conclusions: The accuracy of eNBS was validated within 3 days of variation in GA estimation at 39-40GA. Overestimation by eNBS suggests the possible acceleration of fetal maturity in premature newborns, while underestimation, of the deceleration of fetal maturity in postterm newborns.

Purpose: To examine delivery type of mother who have had a previous cesarean and identify maternal factors related to type of delivery. Methods: The study sample included 60,504 mothers who had delivered through cesarean section. Related variables were categorized as sociodemographic factors (age, residence, health insurance type, income level) and clinical characteristics (14 maternal factor, 4 fetal factor and pre-term). For data analysis, $x^2$ and multivariate logistic regression were conducted. Results: Among the 60,504mothers, 3,075 were delivered through Vaginal Birth After C-Section (VBAC) and the VBAC rate was 5.1%. Underage 34, the VBAC rate increased according to age increases up to 3%. Mothers residing in urban areas had VBAC more frequently than mothers in rural area. Mothers in the high and middle income levels had a greater possibility of having VBAC than mothers in lower income levels. A greater likelihood of increase in repeated cesarean section were found in mothers with maternal and fetal factors. Conclusion: Evidence based nursing practice guidelines and education programs for previous cesarean section mothers and health policy are needed to increase VBAC.

This study investigated the effect of maternal undernutrition during late pregnancy on the growth and development of ovine fetal visceral organs. One hundred Mongolian ewes were mated at a synchronized oestrus and divided into three groups and offered 0.175 MJ ME $kgw^{-0.75}\;d^{-1}$ (Restricted Group1; RG1), 0.33 MJ ME $kgw^{-0.75}\;d^{-1}$ (Restricted Group2; RG2) and ad libitum access to feed (Control Group; CG) during late pregnancy (90 days). Selected animals in each group were slaughtered immediately at d 90 of pregnancy and after parturition (neonatal lambs), and major visceral organs were removed and weighed separately. The results indicated that the weights of lung (p<0.01), spleen (p<0.01), heart (p<0.05), liver (p<0.05) and abomasum (p<0.01) in RG1 were significantly lighter than those of CG. For RG2, only the weights of the lung (p<0.05) and spleen (p<0.01) were significantly lighter than those of CG; when expressed as a percentage of body weight, significance was retained in the spleen (p<0.01) for both restricted groups, but the percentage of brain in RG1 was significantly higher than that in CG (p<0.01). For lung and spleen, the amount of DNA was significantly lower (p<0.01) in both groups of restricted neonatal lambs compared to CG; however, there was a significant difference only between RG1 and CG for protein: DNA ratio (p<0.01). The DNA content of kidney, abomasum and jejunum were decreased (p<0.05) in RG1 neonatal lambs, but protein: DNA ratio in the liver was decreased compared with that of CG (p<0.05). The plane of maternal undernutrition during late pregnancy had a significant effect on the growth and development of fetal visceral organs, which altered ontogeny of fetal organ growth and development. These perturbations in fetal visceral development may have significant implications on postnatal growth and adult health.

다태동물의 경태반성독성학실험시 자중내적 요인의 하나로서 자궁내 착상위치가 태자의 출생시 체중에 미치는 영향을 관찰하고, 급 만성 일산화탄소중독으로 저산소상태를 만들었을 때 이러한 외부 요인이 자궁내적 요인에 어떻게 작용하는가를 관찰하고자 백서를 이용하여 정상대조군 및 급 만성 일산화탄소 폭로군에서의 착상부위별 태자의 출생시 체중을 관찰한 바 다음과 같은 소견을 얻었다. 1) 대조군에 있어서는 자궁중앙부에 위치한 태자가 가장 무거운 출생시체중을 나타내었으며 그 다음이 자궁경부, 난소부의 순서였다. 그러나 부위별 체중은 통계적으로 유의한 차이를 보이지 않았다. 2) 급성 CO폭로군에서는 자궁중앙부의 태자체중이 가장 무겁고 자궁경부, 난소부의 순서로 대조군과 양상이 같았으나, 부위별 태자체중의 차이는 통계적으로 유의하였다. 만성 CO 폭로군에서는 자궁중앙부, 난소부, 자궁경부의 순서였으며 자궁부위별 태자체중의 차이는 유의하였다. 이상의 결과를 통하여 정상상태에서는 태자의 자궁내위치는 출생시 체중에 영향을 주지 않으나, 급 만성 CO중독으로 조직저산소증을 일으킨 경우에는 자궁내 착상부위에 따라 태자의 출생시 체중에 영향을 주는 것으로 나타나 다태동물의 출생시 체중을 종속변수로 사용하는 실험연구에서는 태자의 자궁내 착상부위가 교란변수로서 간주되어야 할 것으로 생각된다.

The combined effect of radiation and ultrasound has been studied in mouse embryos. Radiation and/or ultrasound were adminstered to ICR mice on day 8 of gestation. Intrauterine death, gross malformation, and fetal body weight were selected as indicators of effects. Does of whole-body ${\gamma}-irradiation$ were 0.5 to 2.5 Gy and those of ultrasound were $0.5\;W/cm^2$ to $3\;W/cm^2$. Intrautrine mortality increased with increasing radiation dose ; this trend was more remarkable in combination with ultrasound. Gross malformations such as exencephaly and anophthalmia/microphthalmia appeared frequently in the fetuses treated with both radiation and ultrasound. Decreased fetal weight was observed even in mice treated with 1.5 Gy of radiation or $1\;W/cm^2$ of ultrasound. There was a linear relationship between dose and reduction of fetal weight. The fetal weight was sensitive, precise and easy-to-handle indicator for the effects of growth retardation. Intrauterine mortality and frequencies of exencephaly and anophthalmia/microphthalmia were higher than the sum of those induced by radiation and by ultrasound. The results indicatied that the combined action of radiation and ultrasound on intrauterine death and malformations was synergistic.

In modern society, the amount of alcohol ingestion is increasing at a dangerous level, especially among women. One of reason for increased alcohol consumption is stress caused by social pressures. Alcohol is a kind of depressant of centric nervous system, so it can induce relaxation of body and decrease the stress. The evidence on the effects of alcohol on the fetus is somewhat hazy, whereas that of smoking is quite clear. The literature on the ingestion of alcohol strongly suggests that drinking during pregnancy is associated with teratogenic effect and low birth weight. Therefore, the adverse effect of alcohol ingestion during pregnancy must be informed to public. More remarkable warning sign about alcohol ingestion must be attached on the top of bottles. This can be an effective measure for public education. Also legal sanction or tax imposition for the production of liquor be required. First of all, drinking habit or drinking culture must be changed. In fact, the strongest motivation of drinking in adolescent is a peer pressure which is related to drinking habit or culture. Secondly, early detection and treatment must be required to prevent from fetal alcohol syndrome. Accordingly, drinking history of pregnant women must be assessed as early as possible and health professional should give a warning about the abstinence of alcohol to drinking women. Thirdly, to minimize the adverse effects for mother, withdrawal syndrome by alcohol ingestion must be treated. to correct the malformation by fetal alcohol syndrome(FAS) can be corrected. Sometimes surgical intervention may be required for this purpose.

A clinical study was made on 365 low birth weight infant and 406 normal birth weight infant who had been born at Kangnam St. mary's Hospital during past 3 years from Jan. 1, 1995 to Dec. 31, 1997. the data of this study were gathered through reviewing of medical records. 1. Comparison of general characteristic with of obstetric characteristic 1) Old maternal age, previous abortion and previous LBWI delivery in the group of low birth weight infant(LBWI) mother were more prevalent than those in the group of normal birth weight infant(NBWI)mother 2) Cesarean section, abnormal presentation and multiple pregnancy in the group of LBWI mother were prevalent than those in the group of NBWI mother. 3) regular antenartal care and visiting rate of tertiary hospital in the group of LBWI mother were more prevalent than those in the group of NBWI mother. 2. Frequency of low birth weight infant 1) Anmual average frequency of LBWI was 6.5% and monthly frequency was the highest in January and december. 2) The frequency of LBWI was the highest in 37-40wks of gestational age and was the highest in 2251-2500 gm of birth weight. 3) The frequency of congenital anomaly in the group of LBWI was more prevalent than that of NBWI. 3. Mortality rate of LBWI The mortality rate of LBWI was 9.2%. The highest mortality rate was noted before 27wks of gestational age, less than 1000gm of birth weight and within 12hrs of delivery. 4. The most common complication of pregnant women was pre-term labor, the most complication relating to placenta was premature rupture of membrane(PROM) and the most fetal complication was fetal distress in delivered LBWI. 5. Significant relating factors of low birth weight infant delivery were associated with maternal age, previous delivery, previous low birth weight delivery, pre-eclampsia, anemia, oligohydramnios, PROM, placenta previa, abruptio placenta, fetal sex, fetal distress and congenital anomaly.

Purpose: This study was a comparative study to understand the levels of anxiety, pain and maternal-fetal attachment between women who became pregnant after infertility treatment and became pregnant naturally. Methods: This study used a comparative survey design. Data were collected by 50 couples of natural pregnancy and of who became pregnant after infertility treatment who visited delivery room in C Medical hospital, Seoul. These couples were to have first baby, and cervix dilatation of women was less than 3 cm regardless of diagnosis. Results: The score of anxiety of infertile women was significantly higher than that of naturally pregnant women; however, that of spouses showed no difference. The pain score for infertile women was significantly higher in both the active and transition phases. Pain scores that reported by their spouses did not show differences in either phase. The score of maternal-fetal attachment showed no difference between two groups of women. Conclusion: The result showed the importance of nursing intervention to reduce women's anxiety and pain, through both antenatal-childbirth education programs and assertive nursing interventions. It is necessary to develop and evaluate new intervention which would be more effective for reducing pain and anxiety for couples who became pregnant after infertility treatment.

The adverse effect of diving on the fetus may extend beyond n gestational process and outcome. Primiparous Sprague-Dawley rats were assigned to one of ten exposure schedules during gestatred $PO_2$ level, the following question about the effect of exposing a pregnant female to high partial pressure of inspired oxygen has been raised. 'What effect does an increased maternal $PIO_2$ have on fetal arterial $PO_2$ and therefore on possible fetal oxygen poisoning?' This study was carried out to observe the effects of maternal hyperoxia on gestational process and outcome. Primiparous Sprague-Dawley rats were assigned to one of ten exposure schedules during gestation. The treatment groups were subjected to either the high concentration of oxygen, or the high atmospheric pressure. On day 21 of gestation, laparotomy was performed to examine for number and distribution of implantations and live and resorbing embryos. Fetuses were weighed, and examined for gross malformations. Subsequently, they were fixed, measured in physical parameters, and examined for visceral anomalies. Minor visceral anomalies and anatomical variation was not found. Similarily, there were no significant differences when number of resorptions, mean fetal weights, pregnancy interruption rate were compared by analysis of variance. These results indicate that exposing rats to oxygen at increased atmospheric pressure doese not affect fetal health or survival.
