To assess the effect of an antenatal nutritional status on pregnancy outcome, especially neonatal birty weight, one-day 24hr-recall and two-day recording methods for dietary survey and interview for general and obstetric characteristics of each subject were completed and pregnancy outcome was recorded by phone after delivery. 147 pregnant women attending routinely public health centers in Ulsan were divided into 1st trimester(n=36), 2nd trimester(n=102), 3rd trimester(n=71) by LMP(Last Menstrual Period) because some subjects attended repeatedly in different trimester. The subjects were aged 27.9$\pm$2.9 as mean and the level of education was senior high school and more. 20.4% of subjects experienced spontaneous abortion and 30.0% experienced induced abortion in previous pregnancy. Mean intakes of all nutrients except ascorbic acid were significantly different but dietary composition of energy intakes was not different between trimester. Mineral of calcium, iron and zinc did not meet the RDA for pregnancy outcome was about 20%, which consists of spontaneous abortion (3.4%), caesarian section(15.6%), premature delivery(0.7%) and still births(0.7%). The mean birth weight of neonates is 3.31kg the rate of neonatal birth weight below 10th percentile was 8.4% and the rate of low birth weight(<2.5kg) was 3.1%. By analysis of nutrient factors that influence on the neonatal birth weight (NBW), iron intake correlated negatively and zinc intake correlated positively with NBW in 1st trimester but fat and iron intakes correlated with NBW positively in 3rd trimester. Prepregnancy weight, gestational age at delivery and No. of induced abortion had a positive effects on NBW and No. of spontaneous abortion and te severity of morning sickness had a negative effects on NBW.

Purpose: The aim of this study was to investigate the clinical characteristics of Respiratory syncytial virus (RSV) infection during the neonatal period to provide information that is useful in clinical practice and suggest extension of the palivizumab administration. Methods: Neonates admitted to the National Health Insurance Service Ilsan Hospital neonatal intensive care unit due to respiratory symptoms and for whom multiplex reverse transcription-polymerase chain reaction and multiplex real time-polymerase chain reaction tests were performed between October 2011 and May 2016 were included in this study. Medical records were retrospectively reviewed, and data was collected for 156 neonates. Results: Among the 156 neonates, RSV was detected in 114 (73.1%), non-RSV in 25 (16%), and no virus in 17 (10.9%). The majority were full term infants (92.4%) and peak incidence of RSV infection was in January. Post-natal care center infection was more common in the RSV group (46.6%) than that in the other virus groups (24%, P=0.0243). Clinical symptoms were severe in the RSV group in contrast to that in the non-RSV or others groups. The RSV group frequently needed oxygen therapy (P=0.0001) and the duration of hospital stays were longer (P=0.0001). Conclusion: RSV is a significant cause of respiratory infection in neonates and the severity is higher in contrast to that with other viral causes of infection. Infants in post-natal care centers have a high-risk of developing RSV infections; therefore, palivizumab administration may be considered in this group to prevent hospitalization and reduce the duration of hospital stay.

Influenza virus infection is a zoonosis that has great socioeconomic effects worldwide. Influenza infection induces respiratory symptoms, while the influenza virus can infect brain and leave central nervous system sequelae. As children are more vulnerable to infection, they are at risk of long-term neurological effects once their brains are infected. We previously demonstrated that functional changes in hippocampal neurons were observed in mice recovered from neonatal influenza infection. In this study, we investigated changes in myelination properties that could affect neural dysfunction. Mice were infected with the influenza virus on postnatal day 5. Tissues were harvested from recovered mice 21-days post-infection. The expression levels for myelin basic protein (MBP) were determined, and immunohistochemical staining and transmission electron microscopy were performed. Real-time polymerase chain reaction and Western blot analyses showed that mRNA and protein expressions increased in the hippocampus and cerebellum of recovered mice. Increased MBP-staining signal was observed in the recovered mouse brain. By calculating the relative thickness of myelin sheath in relation to nerve fiber diameter (G-ratio) from electron photomicrographs, an increased G-ratio was observed in both the hippocampus and cerebellum of recovered mice. Influenza infection in oligodendrocyte-enriched primary brain cell cultures showed that proinflammatory cytokines may induce MBP upregulation. These results suggested that increased MBP expression could be a compensatory change related to hypomyelination, which may underlie neural dysfunction in recovered mice. In summary, the present results demonstrate that influenza infection during the neonatal period affects myelination and further induces functional changes in influenza-recovered mouse brain.

Purpose: The purpose of this study is to identify the influencing factors of mother-infant attachment and construct a descriptive model that explains mother-infant attachment during the early postpartum period. Method: The hypothetical model of this study consisted of 8 variables with 23 constructed paths. The subjects of this study were 152 postpartum women. Data was analyzed to test the hypothetical model using covariance structure analysis. Result: The final model which is modified from the hypothetical model improved to Chi-Square 41.92, GFI .95, AGFI .89, RMSR .02, RMSEA .06, NFI .94, and NNFI .95. Mother-infant attachment during the early postpartum period was proven to be influenced directly by neonatal perception, maternal sensitivity, and maternal-fetal attachment and also indirectly by social support, maternal-fetal attachment and maternal identity. These variables accounted for 32% of the variance of the mother-infant attachment during the early postpartum period. Conclusion: It is necessary that the nurses provide postpartum women with an intervention using social support for improving maternal identity and alleviating maternal role strain. It can be helpful to improve maternal sensitivity and in the end it will facilitate the mother-infant attachment during postpartum period.

The purpose of this study is to define the effect of radiation hours on the physiologic jaundice infants. Since there in no full explanation of the way of phototherapy. Data was collected from February, 1993 through August, 1993 at E University Hospital. The subjects consisting of 179 normal newborn who is to receive phototherapy due to bilirubinemia in the early postnatal period. Six groups compared the effectiveness of phototherapy based on hours of radiation ; 6hrs, 9hrs, 12hrs, 15hrs, 18hrs, 21hrs. The results were as follows 1) Effectiveness of phototherapy which means serum total bilirubin decrements were significantly different in groups (F=9.812 p=.000). And follow up study was showed the subset in less than 15hrs groups and more than 15hrs groups. 2) There was no significant difference on the effect of phototherapy between aged after birth. 3) An hours of radiation and the number of stools was not revealed the relationship. The results obtained from this study suggest that 15hrs radiation per day is effective in phototherapy. In the furture, more replication of this study will be contribute for neonatal nursing care.

A polyvalent live Escherochia coli oral vaccine were prepared by the use of 5 field isolates of enteropathogenic E. coli, serotypes 08 : K87, K88a, b ; 0138 : K81, K88a, c ; 0141 : K85a, b, K88a, b ; 0149 : K91, K88a, c and 0157 : K'V17', K88a, c. Some field experiments were conducted to investigate the effectiveness of the polyvalent live E. coli oral vaccine in the prevention of neonatal colibacillosis in piglets suckling orally vaccinated sows. Seventy-nine pregnant sows in an intensive pig farm were vaccinated with oral vaccine 4 weeks prior to farrowing and 19 sows were chosen for control. The piglets suckling vaccinated sows showed a significant protection against neonatal enteric colibacillosis during the 2 weeks observation period from the farrowing but no significant differences in protection between vaccinated and control group were observed with piglets older than 15 days.

Three swine farms which were suffering from slight economic loss due to suckling piglets' diarrhea, were selected to apply commercialized multivalent vaccine for sow use; $SUISENG^{(R)}$ (Hipra, Spain). Farms were pre-diagnosed with clinical symptoms and molecular detection of C. perfringens Type A and C and E. coli pili by PCR. Sows were vaccinated twice 2 ml of the vaccine at 6 and 3 weeks ante partum intramuscularly according to the manufacturer's instruction. All vaccinated sows did not show any adverse reaction or clinical signs; hypersensitivity, fever, granuloma or abscess on the injection site, appetite loss, and so on. Also, no reproductive disorder was appeared in vaccinated sows compared with non-vaccinated control sows. The results suggested that piglets born from vaccinated sows show significantly better performance in regard of the diarrhea index and mean daily weight gain compared with piglets from non-vaccinated sows. Therefore, the commercial vaccine for the prevention of neonatal diarrhea is found to be effective in reducing diarrhea in the first suckling period of piglets after birth.

Background: Respiratory distress syndrome (RDS) is a one of the most common cause of respiratory morbidity and mortality in neonates. This study was conducted to investigate the risk factors for RDS in full-term neonates. Methods: We conducted this retrospective study using medical records. The study group included 80 full-term neonates diagnosed with RDS and hospitalized in the neonatal intensive care unit between January 2012 and December 2016, at Yeungnam University Hospital. We analyzed sex, gestational age, birth weight, delivery method, maternal age, number of pregnancy, history of abortion, and complication of pregnancy. The control group included 116 full-time neonates who were hospitalized with jaundice during the same period. Results: The incidence of full-term RDS was more common in males (odds ratio [OR], 3.288; 95% confidence interval [CI], 1.446-7.479), cesarean section (OR, 15.03; 95% CI, 6.381-35.423), multiparity (OR, 4.216; 95% CI, 1.568-11.335). The other factors rendered no significant results. Conclusion: The risk factors for RDS in full-tern neonates were identified as male sex, cesarean section, and multiparity. Further studies involving more institutions are needed to clarify the risk factors for RDS in full-term infants.
