An infant's sleep varies considerably from that of adults in terms of structure, amount, and breathing pattern. After birth, sleep becomes evenly distributed throughout the day and night. Nighttime sleep gradually increases with the maturation of circadian rhythm, and sleep is gradually consolidated. Electroencephalography characteristics change with age, from early and dominant active (REM) sleep in newborns to increasing NREM sleep. Similar to other elements of growth, the upper respiratory tract and ribcage gradually increase in size with age, and respiratory control also improves. With these changes, sleep patterns also change. At this time that various sleep disorders may appear. Improved understanding of age-dependent changes in infant sleep can help determine the etiology and facilitate diagnosis of infant sleep diseases.

Purpose: The purposes of this descriptive survey study were to describe postpartum depression level and to identify the influence of postpartum depression on maternal role confidence, parenting stress and infant temperament, in order to develop a base for nursing intervention programs for mothers who have postpartum depression. Method: Data were collected from 183 mothers of infants who visited one public health center in Goyang city. The instrument used for this study was a self-report questionnaire to identify the postpartum depression (BDI), maternal role confidence, parenting stress (PSI) and infant temperament (WBL). Results: Of the mothers 42.1% were in the normal range for postpartum depression, 33.3% in the mild group and 24.6% were in the moderate to severe group. There were significant differences in parenting stress, and infant temperament according to level of postpartum depression. There were correlations between maternal role confidence (r=-0.13), infant temperament (r=-0.20), parenting stress (r=0.51) and postpartum depression, and weak negative correlation between parenting stress and infant temperament (r=-0.30). Conclusion: Postpartum depression in the infant period when the mother's role is very important and the effect is not only on the mother's role but also on the infant's growth. It is essential to assess and provide immediate care to mothers who have postpartum depression.

Esophageal atresia (EA) with proximal tracheoesophageal fistula (TEF; gross type B) is a rare defect. Although most patients have long-gap EA, there are still no established surgical guidelines. A premature male infant with symmetric intrauterine growth retardation (birth weight, 1,616 g) was born at 35 weeks and 5 days of gestation. The initial diagnosis was pure EA (gross type A) based on failure to pass an orogastric tube and the absence of stomach gas. A "feed and grow" approach was implemented, with gastrostomy performed on postnatal day 2. A fistula was detected during bronchoscopy for recurrent pneumonia; thus, we confirmed type B EA and performed TEF excision and cervical end esophagostomy. As the infant's stomach volume was insufficient for bolus feeding after reaching a body weight of 2.5 kg, continuous tube feeding was provided through a gastrojejunal tube. On the basis of these findings, esophageal reconstruction with gastric pull-up was performed on postnatal day 141 (infant weight, 4.7 kg), and he was discharged 21 days postoperatively. At 12 months after birth, there was no catch-up growth; however, he is currently receiving a baby food diet without any complications. In patients with EA, bronchoscopy is useful for confirming TEF, whereas for those with long-gap EA with a small stomach volume, esophageal reconstruction with gastric pull-up after continuous feeding through a gastrojejunal tube is worth considering.

In Korea, the concerns about the consumption of soy-based infant formulas have received considerable public attention. In has been known that the n-3/n-6 ratio of soy has a beneficial effect on the health. This study was conducted to investigate whether the soy-based infant formula has an effect on the composition of fatty acids in erythrocytes with regard to the plasma lipid levels in full-term infants. The infants who were delivered at Kyung Hee Medical Center were recruited. Experimental groups were the breast milk group(n=17), soy-based infant formula group(n=12) and casein-based infant formula group(n=19). Anthrophometic and dietary assessments were performed and the composition of RBC fatty acids and blood lipid levels were measured. The body weight, length, chest circumference and head circumference of the subjects were normal growth range showing no significant difference among the experimental groups. The ratio of n-3/n-6 ratio in breast milk, soy-based infant formula and casein-based infant formula were 0.11, 0.14 and 0.13, respectively. N-3/n-6 ratio of the subjects erythrocyte fatty acids for each groups were 0.18, 0.21 and 0.17, respectively. Most of the fatty acids of erythrocyte were not significantly different among the three experimental groups. The blood lipid levels of each experimental group were normal range. The total lipid level of casein-based formula group was higher than that of other experimental groups and LDL-cholesterol level of soy-based formula group was the lowest among the three groups.

The authors made a clinical study of 80 cases of empyema who were diagnosed and treated at department of chest surgery, St. Mary`s Hospital, Chatholic Medical College, during the period of May.l964 through April.1969 and compared the empyema of infant and children with that of adults. 1. In age and sex ditribution, infant was 6 cases, childhood 22 cases and adult 52 cases. The ratio of male to female was 2.2:1. There`s a little difference in infant-childhood but prominence of males over females in adults was being 3. 3:1, in its ratio. 2. The cardinal symptoms were cough [61.3%], fever [60.0%] and dyspnea [52.8%]. The leukocytosis were observed in 83.7% of all cases, 96.2% of infant-childhood and 76.9% of adults. The hemoglobin level showed subnormal in 82.1% of infant-childhood and in 55.8% of adults. 3. Most frequent lesion to predisposing factor of empyema was pneumonia [43.7%],being prominent in infants children [64.3%] to that of adult 4. The Pathogenic organism by culture in 75 cases of empyema were staphylococuss [48%], streptococuss[9.3%], Gram[-] bacilli [9.3%], Klebsiella[2.7%], pneumococcus[4.0%], E. coli [5.4%] and no growth 21.3% in over all. Among the cases of empyema. staphlocal origin was 62.9% in infant-childfood and 39.6% adults. 5. Staphylococci were most susceptible to erythromycin [86. 1%], Kanamycin [75.0%], albamycin [61.7%] and neomycin [52.8%] but most resistant to penicillin, Chtoramphenicol and terramycin. 6. In the treatment of empyema, of 53 cases were closed thoracotomy drainage and the remainder of cases by open thoracotomy, decortication, thoracoplasty and pleuropneumonectomy. we could attain favourable results by only the closed thoracotomy in infant-childhood, 28 cases. 7. The mortality rate was 6.3% in over all; adult 3 cases, infant and children 2 cases. 3 cases of these, were due to staphylococcal infection.

Enterobacter sakazakii, Salmonella typhimurium. and Bacillus cereus were evaluated on inoculated infant formula by gamma irradiation treatment as a method to provide microbial safety. The infant formula inoculated with the major pathogenic bacteria was treated at irradiation dose of 0, 3, 5, and 10 kGy, respectively. After treatment, the samples were individually packaged and stored at $20^{\circ}C$. Microbiological data during storage represented that the populations of E. sakazakii, S. typhimurium, and B. cereus were reduced with the increase of irradiation dose by 4 to 5 log reductions. In particular, E. sakazakii, S. typhimurium. and B. cereus were eliminated at 10, 5, and 3 kGy, respectively. E. sakazakii was the most radiation-resistant, while B. cereus was the least. Our results represent that gamma irradiation below 10 kGy should eliminate the growth of the major pathogenic bacteria in infant formula during storage.
