This study analyzed 10,352 married women to find the correlation between marital equality felt by married women and additional childbirth intentions. Frequency analysis and chi-square test analysis were performed to analyze the general characteristics of the investigator, and studies were conducted through binary logistic regression analysis and interaction analysis to analyze the relevance between each variable and additional childbirth. As a result, the 4-point group based on the 0-point group that lowest marital equality had 2.01 times higher willingness to additional birth. And, the 3-point group and the 2-point group were 1.46 times and 1.41 times higher than 0-point group with marital equality and additional childbirth intentions. In addition, intention of additional childbirth was increased when the higher the number of children, if they own a house, and if wives are non-regular or unemployed. This study analyzed the relationship between married women's intention to give birth additionally, focusing on marital equality. It is suggested that specific and reasonable policies at the macro level are required to improve the fertility rate.

The purpose of this study is to compare the cognition of SIDS as the first step for decreasing the SIDS death rate for the infant and for activity of infant-care in Korea. Participants were 409 child care center directors and 146 parents from 500 child care center directors and 200 parents who using child care center facilities for their children in Seoul. For analysis of research questions, frequencies, Cronbach $\alpha$, t-test,One-way ANOVA, Scheffee test were used with SPSSWIN 15.0. Through this study, we find the child care center directors have good cognition for it, but their effort for SIDS prevention is limited, because they don't have any official prevention education from authorized training center. Even though the parents have a low awareness for SIDS prevention than child care center directors, but they have high score in endeavor for SIDS precaution. Both child care center directors and parents want to receive systematic information from government side. Our infant should have a opportunity to grow up health and stability from reducing the risk of SIDS. In western countries such as U.S.A., U.K. and Japan have studied to decrease the SIDS death rate from thirty years ago, they have already government and social organization for preventing the SIDS. Nowadays, as you know well, our country birth-rate is falling by 1.08, therefore, it is important to decrease the infant death rate for keeping with our population. Also, it is relevant to the child-welfare and the child-safety and more better the child-care.

Purpose : The aim of this study was to evaluate recent improvements in the survival rate of extremely low birth weight (ELBW) infants and to identify perinatal and management factors that are associated with improved survival. Methods : Two groups of ELBW infants who were admitted to our neonatal intensive care unit (NICU) during two distinct eras : November 1994-December 1999 (Period 1 : n=100) and January 2000-April 2004 (Period 2 : n=166) were retrospectively reviewed. Results : Despite the younger gestational age and smaller birth weight of the ELBW infants in period 2, not only did their survival rate increased to 75 percent from 60 percent in period 1, but their incidence of morbidities such as bronchopulmonary dysplasia, confimed sepsis and intraventricular hemorrhage (${\geq}$Grade III) also declined. Factors significantly associated with improved survival included the use of antenatal steroids, a longer duration of nasal continuous positive airway pressure and the absence of intraventricular hemorrhage (${\geq}$Grade III). Conclusion : We believe that optimized clinical practice, that emphasized less invasive care, contributed to the recent improvements in the survival rate of ELBW infants.

The present study was undertaken to evaluate the effect of flushing of ewes with concentrate pellets just before the mating season on their nutrient utilization and reproductive performance on farms. Forty-eight Malpura ewes, 1-5 years old were randomly divided into 2 groups of 24 each (G1and G2). Ewes in both the groups were grazed on natural rangeland from 07.00 to 18.00 hr followed by night shelter in animal shed. G1 ewes were maintained on sole grazing while G2 ewes, in addition to grazing, received concentrate pellets at the rate of 1.5% of their body weight. The mean biomass yield of the community rangeland was 0.46 ton DM/hectare. The intakes of DM (g/kg $W^{0.75}$), DCP (g/kg $W^{0.75}$) and ME (MJ/kg $W^{0.75}$) were higher (p<0.01) in G2 as compared to that of G1 being 86.5, 10.2 and 1.15 and 57.5, 4.7 and 0.75, respectively. The digestibility of DM, OM, CP, NDF and hemicellulose were also higher (p<0.01) in G2 as compared to that of G1 being 57.2, 76.7, 78.9, 51.9 and 81.6 and 50.8, 68.7, 68.4, 45.4 and 74.4, respectively. The conception rate was higher (79.2%) in flushed ewes as compared to that of non-flushed (66.7%). Five of the pregnant ewes died and another 5 aborted in G1 while in G2, 5 ewes aborted with no mortality. The lambing was higher (73.7%) in G2 than that in G1 (37.5%). The birth weight of lambs was higher (p<0.05) in G2 (3.47 kg) than that in G1 (2.95 kg). Further, the birth weight of male lambs was higher (3.28) than that of female lambs (3.14). It is concluded that the biomass yield of the community rangeland in semi-arid region of India is low and insufficient to meet the nutrient requirement of ewes prior to mating season. However, concentrate supplementation at the rate of 1.5% of body weight to ewes during this critical stage enhanced their plane of nutrition, reproductive performance, body condition and birth weights of lambs.

Objective : Owing to advances in critical care treatment, the overall survival rate of preterm infants born at a gestational age (GA) <32 weeks has consistently improved. However, the incidence of severe intraventricular hemorrhage (IVH) has persisted, and there are few reports on in-hospital morbidity and mortality. Therefore, the aim of the present study was to investigate trends surrounding in-hospital morbidity and mortality of preterm infants with severe IVH over a 14-year period. Methods : This single-center retrospective study included 620 infants born at a GA <32 weeks, admitted between January 2007 and December 2020. After applying exclusion criteria, 596 patients were included in this study. Infants were grouped based on the most severe IVH grade documented on brain ultrasonography during their admission, with grades 3 and 4 defined as severe. We compared in-hospital mortality and clinical outcomes of preterm infants with severe IVH for two time periods : 2007-2013 (phase I) and 2014-2020 (phase II). Baseline characteristics of infants who died and survived during hospitalization were analyzed. Results : A total of 54 infants (9.0%) were diagnosed with severe IVH over a 14-year period; overall in-hospital mortality rate was 29.6%. Late in-hospital mortality rate (>7 days after birth) for infants with severe IVH significantly improved over time, decreasing from 39.1% in phase I to 14.3% in phase II (p=0.043). A history of hypotension treated with vasoactive medication within 1 week after birth (adjusted odds ratio, 7.39; p=0.025) was found to be an independent risk factor for mortality. When comparing major morbidities of surviving infants, those in phase II were significantly more likely to have undergone surgery for necrotizing enterocolitis (NEC) (29.2% vs. 0.0%; p=0.027). Additionally, rates of late-onset sepsis (45.8% vs. 14.3%; p=0.049) and central nervous system infection (25.0% vs. 0.0%; p=0.049) were significantly higher in phase II survivors than in phase I survivors. Conclusion : In-hospital mortality in preterm infants with severe IVH decreased over the last decade, whereas major neonatal morbidities increased, particularly surgical NEC and sepsis. This study suggests the importance of multidisciplinary specialized medical and surgical neonatal intensive care in preterm infants with severe IVH.

This study aimed to identify the factors influencing the intentions of employed married women, aged 19 and above, with no prior experience of childbirth, to give birth to their first child. First, the intention of employed married women to give birth to their first child showed a moderate level of inclination, with slightly higher scores reflected in the subvariables of perceived marital value and perceived child value both within family values, while the effect of perceived gender role value was generally higher than the midpoint. Perception of work-life balance was generally a moderate influence, with the subvariable of balancing work and family being slightly higher than the midpoint in terms of influence. Second, the intention to give birth to a first child was clearly associated with the level of education and showed a positive correlation. However, this intention was negatively correlated with age, perceived child values, perceived marital values, and residential tenure. Third, pregnancy intention was influenced by age, educational level, perceived value of children, perceived value of marrriage, and work-life balance. This study provides meaningful assistance in understanding current low birth rate by gathering data on the preferences of married working women in relation to childbirth and by presenting the diverse perspectives of the women.

This study was attempted for clinical investigation regarding with Apgar score changing phase of newborns and their sucking power related the score and weight. The data for this study obtained from 545 newborns who were born at Dept. of obstetric WooSok Hospital, Korea University from Jan. to Sept.. 1373. It is hoped that this study will contribute to nursing care planning of newborns in nursery. The Apgar score was checked in the delivery room at 1 minute after delivery by Doctor and rechecked at 30 minutes and 1 hour after delivery by nurses. The results obtained were as follows: 1. The total newborn numbers at 1 minute after delivery were 545, at 30 minutes were 542 (3 dead) and at 1 hour were 540. The babies were divided into 3 groups by the Apgar score. The frequency of group 1 (score 1 to 4) at each times were 5.0%, 0.9%, 0.4%, group 2 (score 5 to 7) 11.2%, 4.1%, 1.7% and group 3 (score 8 to 10) 83.8%, 95.0%, 97.9%. 2. The group I was found most frequently among the cases of less than 2, 500g and group 3 was found among the cases over 2.500g. It was found that there was a tendency of delaying in recovery process of low score among the premature and low birth weight newborns. 3. The type of delivery, breech and other I e was found worst and C-Section was the second, however normal spontaneous delivery was found the best. 4. In observation of sucking power of the newborn related its score and weight, good, fair, poor marks were given. But for convenience of statistical analysis. good and fair was collected together and poor alone evaluated. The result of group 1.2 examined statistically by F.E.T shown no relation between newborn weight and sucking power. however group 3, examined by X$^2$test shown very significant relation between newborn weight and sucking power. 5. The mortality rate of newborn while they were in hospital was found 2.6% to 545 of birth and all cases of dead belonged to group 1 at 1 minutes after delivery. 64.3% of the dead was found among the cases less than 2, 500g. 6. It was found that in this observation premature and Newborn asphyxia had influence to low score at birth. Conclusively, good anthemata carr should be emphasized in order to prevent main causes of these and should avoid abnormal delivery as possible.

Objectives: This study was conducted to investigate how willingness to have an additional childbirth was related to mother's general characteristics and various reasons for avoiding an additional childbirth. Methods: By using organized questionnaire, we had face-to-face interviews with 722 mothers who had 12 to 36 months child in a urban-rural area of Chungcheongnam-do from 14 February to 19 February in 2005. Questionnaires included general characteristics composed of age, monthly income, number of children, major carers and mother's job status, and 6 reasons for avoiding an additional childbirth. We performed chi-square test and multiple logistic regression analysis. Results: Of 722 mothers, 66.5% had no willingness to have an additional childbirth. In the multiple logistic regression analysis, old age of mother(95% CI of OR: 1.084-1.190), two or more children(95% CI of OR: 6.97-15.602) and weak norm about need for a child(95% CI of OR: 1.633-29.352) were independent related factors with willingness to have an additional childbirth. Conclusions: In our study, 2/3 women who already had children were appeared to have no willingness to have additional childbirth. Policies about family planning and controlling birth rate should be focused on eliminating barrier to additional childbirths.

Cryptorchidism or undescended testis is the single most common genitourinary disease in male neonates. In most cases, the testes will descend spontaneously by 3 months of age. If the testes do not descend by 6 months of age, the probability of spontaneous descent thereafter is low. About 1%-2% of boys older than 6 months have undescended testes after their early postnatal descent. In some cases, a testis vanishes in the abdomen or reascends after birth which was present in the scrotum at birth. An inguinal undescended testis is sometimes mistaken for an inguinal hernia. A surgical specialist referral is recommended if descent does not occur by 6 months, undescended testis is newly diagnosed after 6 months of age, or testicular torsion is suspected. International guidelines do not recommend ultrasonography or other diagnostic imaging because they cannot add diagnostic accuracy or change treatment. Routine hormonal therapy is not recommended for undescended testis due to a lack of evidence. Orchiopexy is recommended between 6 and 18 months at the latest to protect the fertility potential and decrease the risk of malignant changes. Patients with unilateral undescended testis have an infertility rate of up to 10%. This rate is even higher in patients with bilateral undescended testes, with intra-abdominal undescended testis, or who underwent delayed orchiopexy. Patients with undescended testis have a threefold increased risk of testicular cancer later in life compared to the general population. Self-examination after puberty is recommended to facilitate early cancer detection. A timely referral to a surgical specialist and timely surgical correction are the most important factors for decreasing infertility and testicular cancer rates.

To understand the current status of neonatal surgery in Korea, a survey was made among the 36 members of the Korean Association of Pediatric Surgeons. The response rate was 75 % (26 surgeons in 20 hospitals). Five hundred fifty three neonatal surgical patients treated in 1999 were analyzed. Regional numbers of patients were closely related to the regional population in most areas. Ano-rectal malformations (17 %), pyloric stenosis (16 %), Hirschsprung's disease (13 %), atresia/stenosis of the gut (11 %), esophageal atresia (8 %) were the most common anomalies treated. The majority of operations were done within the first week of life. Seventy one per cent of cases were major life threatening or so-called neonatal index cases. Over-all mortality was 8 per cent. Higher mortality was observed in patients with diaphragmatic hernia (26 %), gastro-intestinal perforation (18 %), NEC (18 %), and esophageal atresia(14 %). Higher mortality was observed in patients with extremely low birth weight (33%) and low birth weight (18 %). Associated anomalies were observed in 20 %. Prenatal ultrasound was performed in 36 per cent with sensitivity of 20 %. Result of this study was compared to the previous report (1994) and that of Japan (1998).
