A ventriculo-peritoneal shunt is a standard surgical management for hydrocephalus, but complications may impede the management of this disease. Obstruction of the catheter is one of the most common complications and manifests clinically in various ways. Intraparenchymal cyst development after shunt malfunction has been reported by several authors, but the underlying mechanism and optimal treatment methods are debatable. The authors report a case of intraparenchymal cyst formation around a proximal catheter in a premature infant after a ventriculo-peritoneal shunt and discuss its pathogenesis and management.

Purpose: This study was done to identify degrees of factors influencing parenting self-efficacy in grandmother raising infant and toddler. Method: A convenience sample of 121 grandmothers whose grandchild was between 3 to 36 months old was used. The variables were health status, health problems and life event. The data were collected through a questionnaire survey and descriptive statistics, t-test, ANOVA with Scheffe test, Pearson correlation coefficients and stepwise multiple regression were used to analyze using SPSS WIN 12.0. Results: The average score for parenting self-efficacy was 39.39(SD=5.09), somewhat higher than moderate in level. Factor that was significant in influencing parenting self-efficacy was life event. This factors accounted for 14.6% of explained variance. Conclusions: It was found that the life event was influenced to parenting self-efficacy in grandmothers raising infant and toddler. From this study it is proposed that there is a need to develop programs and policies which support them. Ultimately a good care environment for children will be good for the young children's growth and development.

Tracheomalacia can be a life threatening upper air way obstructive disease in an infant and vascular rings can be also a major rare cause of tracheoesophageal obstruction. These two rare entities can be combined in one patient because the vascular ring can cause secondary tracheomalacia during development of fetus. The diagnosis of this combination and adequate surgical correction is occasionally difficult. This is a report of an infant who had not diagnosed tracheomalacia associated with vascular ring until 5 months of age because of the prolonged tracheal intubation. The rigid bronchoscopic examination performed under impression of tracheomalacia revealed a concentric tracheal collapse, an unusual bronchoscopic findings of tracheomalacia, which raised a suspicion of the tracheal compression by vascular rings. The 3-D reconstructive DT aortography clearly demonstrated the double aortic arch. The patient was treated surgically by simple division of the left aortic arch and aortopexy with good result. The vascular ring such as double aortic arch should be considered during the diagnosis of tracheomalacia in infants. If the tracheomalacia is associated with vascular ring, simultaneous surgical correction should be performed.

Purpose: The purpose of this study was to determine the factors that may affect quality of life of mothers who delivered premature infants. Methods: With survey design, data were collected from 145 mothers of premature infants with corrected age of 2 months to 12 months from January 9 to February 2, 2017. Quality of life was assessed with two measures of direct survey in the selected hospital and online survey. A self-report questionnaire was administered regarding personality of the mothers and the infants, postpartum depression, parenting stress, social support, and the quality of life. Data were analyzed using t-test, ANOVA, Pearson correlation coefficients, and multiple regression. Results: The quality of life of the mothers of the premature infants was influenced by postpartum depression, parenting stress, parents-infant dysfunctional interactions, and social support accounted for 65% of the variance. Conclusion: These results indicate that early screening and continuous management of postpartum depression during postpartum period are important to improve the quality of life of the mothers of the premature infants. Education program and information and social support systems need to be developed to monitor mother-infant interaction and their role development.

Purpose: The aims of the study were to develop mobile application for postpartum care of first-time mothers and to validate it's effect. Methods: Using a nonequivalent control group pretest-posttest design, 52 first-time mothers were recruited (26 each in experimental and control) and the experimental group used the mobile application for 6 weeks after delivery. Postpartum self-care knowledge and confidence, infant care knowledge and confidence, and postpartum depressive mood (Edinburgh Postnatal Depression Scale) were measured before discharge from the hospital and 6 weeks later. Results: Women who have used the postpartum care mobile application reported higher levels of postpartum self-care knowledge (p=.030) and confidence (p=.023) infant care knowledge (p=.001) and confidence (p=.004), while scores of postpartum depression (p=.021) were lower than those in the control group. Conclusion: The postpartum-care mobile application developed in this research may be effective in reinforcing knowledge and confidence for postpartum self-care and infant care and in reducing postpartum depressive mood.

Purpose: The purpose of this study was to identify factors influencing parenting confidence in first-time mothers and to provide basic data for development of maternal role education programs. Method: The participants were 194 first-time mothers of babies aged 1-6 months who visited well-baby clinics in 4 hospitals. Instruments used in this study were self-reported questionnaires. The data were analyzed using descriptive statistics, Pearson correlation coefficient and stepwise multiple regression. Results: The parenting confidence level was moderate with a mean score of 3.26(range 1-6). Infant temperament was significantly correlated with maternal role confidence. Maternal role confidence was significantly correlated with child-rearing environment. Infant temperament and parenting stress were significant predictors explaining 50% maternal role confidence. Conclusions: Nursing Interventions to promote parenting confidence among first-time mothers of infants in their first year are needed to improve maternal perception to infant temperament and reduce parenting stress.

The purpose of this study was to extend our understanding of the developmental antecedents of delay of gratification in infancy. The first goal was to examine direct effects of one feature of an infants’ temperament and of positive and negative parenting assumed at age one on children’s delay of gratification six months later. The second goal of the study was to test the interactive effect of early infant temperament and parenting on children’s delay of gratification. It was hypothesized that 1) less negative infants at 12 months would delay gratification longer six months later, 2) children of parents who provided more positive and sensitive feedback would delay gratification longer than children with parents who were more negative and less sensitive, and 3) there would be differential prediction of parenting for children who scored high and low in negative emotionality as infants. Toward this end, 81 infants were observed interacting at one year of age with their mothers and fathers during laboratory assessments to obtain measures of parenting and infant negative emotionality. At 18 months of age, the child’s capacity to delay touching attractive objects was measured. The main effects of infant negative emotionality and of mothering on children’s delay of gratification were not detected at standard levels of significance. Differential effects of parenting on children’s delay of gratification for infants with low or high negative emotionality, too, were not detected. However, the anticipated effect of fathering on delay of gratification was found in some analyses, indicating that the more positive fathering children received, the longer they could delay gratification in the laboratory six months later.

A rapid and simple analytical method for L-carnitine was developed for infant and toddler formulas by liquid chromatography tandem mass spectrometry (LC-MS/MS). A 0.3 g of infant formula and toddler formula sample was mixed in a 50 mL conical tube with 9 mL water and 1 mL 0.1 M hydrochloric acid (HCl) to chemical extraction. Then, chloroform was used for removing a lipid fraction. After centrifuged, L-carnitine was separated and quantified using LC-MS/MS with electrospray ionization (ESI) mode. The precursor ion for L-carnitine was m/z 162, and product ions were m/z 103 (quantitative) and m/z 85 (qualitative), respectively. The results for spiked recovery test were in the range of 93.18-95.64% and the result for certified reference material (SRM 1849a) was within the range of the certificated values. This method could be implemented in many laboratories that require time and labor saving.

Objective: The purpose of this study is to investigate the effects of maternal parenting efficacy and emotional expression on infant's social emotional development. Methods: The subjects of this study were 269 infants and their mothers who attended day care centers in G district of S city and the data was collected by survey. The collected data were analyzed by frequency analysis, t-test and ANONA test using SPSS 16.0 program, $Scheff{\acute{e}}$ test by post test, correlation analysis and multiple regression analysis. Results: First, parenting efficacy, emotional expressiveness, and social emotional development of infants showed differences according to age, participation time, and academic background. Parenting efficacy showed a significant difference in age and parenting time, and emotional expressiveness showed significant difference in education and parenting time. Infant's social emotional development showed a significant difference in educational attainment and parenting time. Second, maternal parenting efficacy and emotional expressiveness were found to have an influence on infant's social emotional development. Conclusion/Implications: Maternal parenting efficacy and emotional expressiveness seem to influence the development of social emotions in infants, and these results suggest that, in order to grow the children healthy in social, emotional aspect, various education programs which could improve parenting efficacy and positive emotional expression are necessary.
