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.

Metabolic acidosis is commonly encountered issues in the management of critically ill neonates and especially of preterm infants during early neonatal days. In extremely premature infants, low glomerular filtration rate and immaturity of renal tubules to produce new bicarbonate causes renal bicarbonate loss. Higher intake of amino acids, relatively greater contribution of protein to the energy metabolism and mineralization process in growing bones are also responsible for higher acid load in premature infant than in adult. Despite widespread use of sodium bicarbonate in the management of severe metabolic acidosis, use of sodium bicarbonate in premature infants should be restricted to a reasonable but unproven exception such as ongoing renal loss. Despite concern about the low pH value (<7.2) which can compromise cellular metabolic function, no treatment guideline has been established regarding the management of metabolic acidosis in premature infants. Appropriately powered randomized controlled trials of base therapy to treat metabolic acidosis in critically ill newborn infants are demanding.

The home environments, daily activities, caregiving behaviors of mothers, infant's verbal behaviors, attachment to mothers of home-reared infants from low SES families were observed. 30 two-year-old home-reared infants and their mothers were observed at home by the time sampling method. The HOME scale, the behavioral checking lists for caregiving behaviors and for the infants' verbal behaviors, and the Attachment Q-set were used for the observation. the total HOME scores were in the middle range and the scores of "Provision of apropriate play materials" was relatively high, but "Avoidance of restriction and physical punishment" was low. The most frequent caregiving behaviors shown by mothers were " Facilitating verbal development" and "Positive social-emotional inputs". The most frequent verbal behaviors shown by infants were " Information exchange" and " Language interpretation" . The infants' attachment security scores of their mothers tended to be low.

One- to three-month-old infants (n=232) were compared their upper arm cumference and skinfold thickness(triceps, subscapular) by feeding methods in cross-sectional study. There were two groups : breast-fed(BF) and formula-fed groups(FF). As reported previously, weight, length, head and chest circumferences of these infants were good, and overall growth status was not significantly different by feeding methods, but weight, weight velocity and chest circumference of formula-fed infants were higher than breast-feds at 3month, significantly. Hear, the triceps skinfold thickness of infants at 1, 2, and 3 postpartum months were 7.4, 9.5 and 10.5 mm, respectively. The triceps skinfold thickness of breast-fed infants were higher than formula-feds at 1 and 2 postpartum month, but at 3 month that of formula-fed infants was greater than breast-fed infants, insignificantly. The subscapular skinfold thickness of infants were 6.4, 9.2 and 10.6 mm at 1 to 3 postpartum months, respectively. The upper arm circumference of infants were 11.7, 13.4, 14.3cm, and the arm muscle diameter were 34.5,39.3 and 41.7cm at one to three postpartum months, respectively. The upper arm circumference of male infants was higher than females at 2, 3 postpartum months. Overall, there were no signifiant differences between feeding methods in triceps and subscapular skinfold thickness, upper arm circumference and arm muscle diameter. But 3-month-old formula-fed male infant showed bigger significantly in arm circumference than the breast-feds. From this survey, long-term survey on growth and body composition of large scales might be necessary to determine the effect of feeding methods of infants after 3 months and to set proper body composition standard for infant.

The present analysis was undertaken to find out the relationships between birth weight & Apgar Score of newborn infant & maternal factors. The medical records of 1436 newborn infants who had been at the Korea University III Seoul from January. 1.1984. to December. 31. 1985, were examined. Measurements include weight and Apgar Score. As the possible factors influencing the birth weight & Apgar Score of newborn infant, 9 variables such as : mother's age, frequency ·of pregnancy, frequency of fullterm delivery, frequency. of premature, frequency of abortion, mother's hemoglobin level, complications during pregnancy gestational period and infant sex at birth were selected among the items recorded in the medical records of newborn infants and their mothers. The weight & Apgar Score of newborn infants were compared separately by sex with group percent of those variables. The results were summarized as follows: 1. All of those factors chosen are supposed to be influencing upon the birth weight and Apgar Score examined at birth indirectly through inducing early termination of pregnancy. 2. The most influencing variable of birth weight of newborn infants was gestation period. The most influencing variable of Apgar Score of infant newborn was gestation period. 3. The relationships of those influencing factors are more clear on the birth weights of newborn than on the Apgar Score. 4. More then half of low birth weight infants are turned out to be physiologically normal through the evaluation by Apgar Scoring. Conclusively, All of those factors chosen are supposed to be influencing upon the birth weight and apgar score examined at birth indirectly through inducing early termination of pregnancy.

Purpose: Mothers' postpartum depression is a worldwide health concern that produces compromising effects on their infants. This study was conducted to compare the infants' temperament and health problems according to the presence of maternal postpartum depression. Methods: Data were collected from May to October in 2009. The sample was 137 mothers at one month postpartum. The Edinburgh Postpartum Depression Scale (EPDS) was used to assess depressive symptoms. Results: At one month postpartum, 22.6% of mothers were classified as having postpartum depression. Infants of depressed mothers were more frequently classified as difficult temperament infants. They showed lower scores on the amenability, rhythmicity and persistency and higher scores on activity in temperament. Also, infants of depressed mothers reported more infant health problems at one months. Maternal depression showed significant negative correlations with family functioning, social support and marital satisfaction. Conclusion: Study findings show that postpartum maternal depression is associated with infants' temperament and health, and thus screening and early interventions for postpartum depression would promote the health of both the mother and infant.

The purpose of this investigation was to examine whether early child-care experience, alone or in combination with mother/child factors, was associated with emotion regulation. Participants were forty 12-18 month-old infants, their mothers and their caregivers. Infants were observed in the Strange Situation to assess the pattern of emotion regulation. Mothers were interviewed, given Questionnaires, and observed in play. Caregivers were observed in child care to assess the caregiving environment. There were significant main effects of good quality child care on open emotion expression and heightening emotion expression. Significant interaction effects revealed that infants were more likely to be open emotion expression when high maternal sensitivity /responsiveness was combined with good quality child care, or nonmaterial care initiated prior to six month of age. Infants were more likely to be minimizing emotion expression when low maternal sensitivity/responsiveness was combined with nonmaternal care initiated after six month of age, or more than one care arrangement. Difficult temperament infants received nonrelative care were somewhat more likely to be minimizing emotion expression. Infants were more Likely to be heightening emotion expression when high maternal sensitivity/responsiveness was combined with relative care. Boys experiencing nonrelative care were more Likely to be heightening emotion expression.

Fourty-three infants underwent intracardiac repairs within the first 12 months of life. Mean age was 7 months and mean weight was 6.7 kg. A quarter of them were below 5 kg. Overall mortality including complex anomalies was 17.9%. Thirty-four infants with a ventricular septal defect[VSD were treated. Three infants[8.8% died in the early postoperative period, but only one[3.7% of the infants without having associated lesions was dead. VSD was repaired either by the incision on the right atrium, pulmonary artery, or right ventricle. Postoperative right bundle branch block[RBBB occurrence were different according to the approach: 30.8 % in pulmonary arteriotomy, 37.5 % in atriotomy, and 42.8 % in ventriculotomy. Surgically induced heart block did not occur in any patient, but 10 had temporary arrhythmia, and 11 patients were under temporary pacing from one day to 4 days without any persisting rhythm disturbances. Pulmonary hypertension was present in 29 infants preoperatively, and seven of them developed postoperative elevation of the pressure. Infants complicated with pulmonary hypertensive crisis were managed successfully. Inotropics were necessary in 55.8 % of the infants and vasodilators in 37.2 %. Platelet transfusion were needed in 10 cases who required 272 ml in average, but one who died from sepsis consumed 5,370cc of platelets. And we discuss complications and causes of deaths.

The purpose of this study was to examine the relationship between infants' turn-taking and vocabulary development during a one-year longitudinal study. Participants of this study included 46 infants who participated in both of the 1st and the 2nd tests. The infants' turn-taking frequencies were observed during mother-infant's free play for 10 minutes. The infants' vocabulary was investigated with MCDI-K for the 1st test and PRES for the 2nd test. The collected data were analyzed using both t-test and Pearson's correlation. The research results were as follows: First, the turn-taking frequencies and vocabulary of infants increased with age groups. Second, there was positive relationship between the turn-taking and the receptive vocabulary in group A at T1. Third, there were significant differences in receptive vocabulary at T1 and expressive vocabulary at T2 among group A according to the infants' turn-taking levels.
