The purpose of this study is to first discriminate and assess those infants who appear healthy in appearance but who could face possible risk factors in the future and, secondly, to identify those infants who may have difficulties in their developmental stages. The subjects of this study consisted of 35 full-term infants (39-40 weeks) and 33 pre-term infants (34-35 weeks). The infants' voices were recorded for three minutes, for which EDIROL by Roland and a stand-type microphone made by SONY were used. This was done to discern the value of the Breath unit (B-unit) and the fundamental frequencies ($F_0$). It was found that there were significant differences in terms of F0 since the pre-term infants had higher F0 than the full-term infants, showing a result of 436.4 Hz for the full-term infants and 460 Hz for the pre-term infants (p<.05) There was an average rate of 4.01 for the full-term infants and 4.02 (SD=1.69) for the pre-term infants in shimmer. For NHR, it was observed .44 for the full-term infants and .50 for the pre-term infants, thus revealing no significant differences in these observations. This study shows that the crying of newborn babies is related to their physical conditions and it is a sensatory response to these conditions. Furthermore, this study could be helpful for the early detection and measurement of newborn babies who look clinically healthy but could be at risk through acoustic and physiological analyses.

Ecological studies have indicated that the essential fatty acids in maternal and umbilical cord blood samples are associated with gestational length and birth weight. The objectives of this study were to examine serum fatty acid concentration, particularly $\omega$3 fatty acids, in maternal and umbilical cord blood and to investigate the relationship of serum fatty acid levels in the blood of the mother and of the umbilical cord. Subjects consisted of 30 full-term and 30 pre-term mothers and neonates of both groups. Serum levels of fatty acids were measured by gas chromatography. The concentration of total saturated fatty acids in pre-term pregnant women was significantly higher than that of the full-term group (p<0.05), however, the maternal level of $\omega$3 fatty acids in the pre-term group was significantly lower than that of the full-term pregnant women (p<0.05), Moreover, the concentrations of $\alpha$-linolenic acid and eicosapentaenoic acid in full-term pregnant women were significantly higher than those of the pre-term group. In umbilical cord blood, the levels of total $\omega$3 fatty acid and arachidonic acid were significantly lower in the pre-term group than in the full-term group (p<0.05). Based on the coefficient of correlation between serum fatty acids in the mother and the umbilical cord, it turned out that in the full-term group, the newborn's umbilical cord serum fatty acids were not influenced by the levels of serum fatty acids in the mother. However, in the pre-term group, it seems to have positive correlations in terms of the levels of SFA, MUFA, PUFA and $\alpha$-linolenic acid. This study suggests that a lower status of $\omega$3 fatty acids in maternal and umbilical cord blood probably is a risk factor for pre-term birth.

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.

Testicular torsion is rare in newborn infants. However, its frequency has increased, most of which are reported in full-term infants. We diagnosed and treated testicular torsion in an extremely low birth weight infant (ELBWI). A $2{\times}2cm$ red mass was palpable in the left groin of a 24-week-old, 745 g, male newborn at 23 days of age. Left testicular torsion was diagnosed, and emergent orchiopexy was performed. Careful physical examination is needed in cases suspicious of testicular torsion in ELBWIs with cryptorchidism. Moreover, early diagnosis and emergent exploration are necessary to prevent complications such as the risk of anorchia.

Hemolytic disease in a newborn that causes early jaundice is common. It is often due to the Rh (D) and ABO incompatibility, but rarely due to unexpected antibodies. Among these unexpected antibodies, the anti-$Di^a$Dia antibody rarely occurs. The anti-$Di^a$ antibody was observed in the serum and red-cell eluate of an infant, and in the serum of his mother. The frequency of the appearance of the $Di^a$ antigen in the Korean population is estimated to be 6.4-14.5%. This paper reports a case of hemolytic disease in a newborn associated with the anti-$Di^a$ antibody. A full-term male infant was transferred to the authors' hospital due to hyperbilirubinemia the day after his birth. The laboratory data indicated a hemoglobin value of 11.6 g/dL, a reticulocyte count of 10.6%, a total bilirubin count of 14.4 mg/dL, a direct bilirubin count of 0.6 mg/dL, and a positive result in the direct Coombs' test. Due to the identification of an irregular antibody from the maternal serum, an anti-$Di^a$ antibody was detected, which was also found in the eluate made from the infant's blood. The infant had been treated with phototherapy and intravenous immunoglobulin since the second day after his birth and was discharged due to an improved condition without exchange transfusion. Therefore, in cases of iso-immune hemolytic disease in a newborn within 24 hours from birth who had a negative result in an antibody screening test, the conduct of an anti-$Di^a$ antibody identification test is recommended due to the suspicion of an anti-$Di^a$ antigen, followed by early administration of intravenous immunoglobulin.

Purpose: Glucose has been recommended as an analgesic for mild to moderately painful procedures in neonates. The goal of this study was to assess the optimal dextrose concentration for pain control in newborns. Methods: This prospective, randomized, blinded clinical trial included 116 healthy full-term newborns. The neonates were randomly assigned to the following four groups by drawing straws: groups receiving sterile water or a 10%, 20%, or 40% dextrose solution orally. Each group was treated with the assigned solution prior to hepatitis B vaccination. The Neonatal Facial Coding System (NFCS) and the Neonatal Infant Pain Scale (NIPS) scores were evaluated before, immediately after, and 2 minutes after the injection in all neonates. Premature Infant Pain Profile (PIPP) scores were evaluated during the injection. All procedures were video-recorded, and pain scores were assessed by two independent observers who were not involved in the care of the newborns studied. The pain scores were compared among the four groups. Results: The 40% dextrose solution significantly reduced the NFCS (P=0.002) and the PIPP scores (P=0.001) compared with sterile water. No hyperglycemic events were noted in the study subjects 2 hours after the injection. Conclusion: The 40% dextrose solution effectively relieved pain due to intramuscular injection in full-term newborns without causing hyperglycemic events. However, the 10% and 20% dextrose solutions did not affect neonatal pain scores.

The purpose of this study was to observe and describe the maternal attachment behavior during the mother's first interactions with her newborn and define the factors contributing to differences in maternal attachment behavior. Observations of the mother's first interaction with her newborn can offer valuable information about the mother-infant relationship, and it provides an opportunity for planning individulized care for them. Data was collected from Sep. 1, 1950 to Oct.30, 1980 at Ewha Womans University Hospital. Maternal attachment behaviors of healthy full-term infants were observed and recorded on the .maternal attachment tool and analysed by the use of means, standard deviations and ANEVA test. The following trends of maternal behaviors were observed: 1. Identifying behaviors was the predominant mode and all of the mothers inspects baby's body features. 2. Modalities of interaction, that is, touching was initiated on the babies extremities and heads (57.3%) rather than the trunks (8.7%) and mothers touched their infants with their fingertips (58.2%) more than palm touching (14.6%) 3. Care-taking activities performed by the mother were negligible at the first interaction. 4. Parity of mother, sex of infant, age of mother, planned pregnancy, length of visits by mother to infant appeared to have significant influence on the maternal attachment behaviors.
