Ureteropelvic junction obstruction is one of the common causes of hydronephrosis in infancy and childhood. Most cases of ureteropelvic junction obstruction are diagnosed prenatally and are usually asymptomatic. Although less common, older children can experience ureteropelvic junction obstruction that presents with symptoms including flank or abdominal pain. Here, we present the case of a nine-year-old healthy girl who had repeated flank pain and abdominal symptoms, with mild left hydronephrosis, for several months. Computed tomography that was performed during the period of acute flank pain revealed aggravated hydronephrosis on her left kidney, which was secondary to an ureteropelvic junction obstruction. She underwent laparoscopic pyeloplasty, and a crossing vessel that passed the ureteropelvic junction was identified. In addition, we reviewed the current literature of this rare entity.

The assessment of children's nutritional intakes is important because any nutritional inadequacies or toxicities may have adverse consequences. Studies on the nutritional intakes of Korean children are limited. The aims of this study were to determine anthropometric indices, estimate selectee nutrient intakes of young Korean children, and compare these intakes with current Dietary Reference Intakes for Koreans. This study included 136 healthy children(65 boys, 71 girls), 2-6 y old, living in Kwangju, Korea. Weights and heights were measured. Three consecutive 24-h food recalls were obtained. According to International Obesity Taskforce BMI cutoffs, 8% were overweight and 2% were obese. The energy intakes of 40% were < Korean Estimated Energy Requirements, while all subjects consumed $\geq$ Korean Estimated Average Requirement(EAR) for protein. The majority of the children consumed > Korean EAR for iron, zinc, vitamin $B_1$, vitamin $B_2$, vitamin $B_6$, and niacin. Vitamin E intakes of 65% of the Korean children were < Korean Adequate Intake, and approximately half of the subjects had < Korean EAR for calcium and for folate. Many young children in Kwangju, Korea, likely have inadequate status of calcium, folate, and vitamin E.

Purpose: This study aimed to identify the longitudinal effects of children's temperament on maternal depression. Methods: Data from a longitudinal cohort of the Panel Study of Korean Children (PSKC) from 2010 to 2012 were analyzed using hierarchical linear modeling. The survey included 1,721 mother-child dyads. The mothers reported on their children's temperament and on maternal depression. The children's temperament was measured by the Emotionality, Activity and Sociability-Temperament Survey for Children-Parental Ratings, while maternal depression was measured by the Kessler 6 Psychological Distress Scale. Results: The results showed that both children's temperament and maternal depression were relatively stable when the children were between the ages of 2 to 4. The mean maternal depression scores were 11.83 in 2010, 11.88 in 2011, and 11.75 in 2012. There were significant negative correlations between the maternal depression scores and children's ages, and sociability and activity subdomain scores ranged from r=-.05 to -.11 (p<.05). There was a significant positive correlation between children's emotionality subdomain scores and maternal depression scores (r=.35, p<.001). Children's temperament rament (emotionality: β=0.26, activity: β=-0.07, and sociability: β=-0.03) were significant factors in maternal depression. Conclusion: These findings indicate the need for the early assessment of and intervention for children's temperament and maternal depression. The results of this study will provide basic data for the development of nursing education programs related to early assessment and intervention to improve the health and quality of life of young children and mothers.

Objective: The purpose of this study was to explore the structural relationships among parents' and teachers' autonomy support, children's basic psychological needs, and children's participation in decision-making. Methods: The participants were 687 elementary school students (5th and 6th grades) in Seoul and Gyeonggi-do. The data were analyzed using SEM. Results: First, parents' and teachers' autonomy support had a direct effect on children's participation in decision-making. Second, parents' and teachers' autonomy support had an indirect effect on children's participation in decision-making through the children's basic psychological needs. Third, children's basic psychological needs mediated the effects of parents' and teachers's autonomy support and children's participation in decision-making. Conclusion: The findings suggest the importance of the mediating effect of children's basic psychological needs, between parents' and teachers' autonomy support and children's participation in decision-making. The findings can be used as an important basis for prospective research and practices for improving children's participation in decision-making.

This study was designed to investigate the relation between mother's interaction strategies and self-regulation of young children from a Vygotskian perspective. The hypotheses of this study were: 1) The self-regulation of young children will improve with increase in age, 2) the use of mothers' interaction strategies will increase as child's age decreases, 3) mothers' directiveness in the mother-child interaction depends on the age of child and socio-economic level, and 4) mothers' directiveness in the mother-child interaction will have negative relationship with child's self-regulation. The subjects of this study were 60 mother-child dyads with three different age-of-child groups (3-, 4-, and 5-year-olds). They were further divided into higher and lower socio-economic groups. A puzzle task was used for the measurement of self-regulation. The task consisted of two identical puzzles with one used as the model. The collected data were analyzed by ${\chi}^2$, one-way and two-way analysis of variance, and Pearson's r. Self-regulation of the young children improved with increase in age (P < .05). The use of mothers' interaction strategy decreased as the children's age increased (P < .05). Mothers' directiveness in the mother-child interaction was influenced by the age of child (P < .01) and by socioeconomic level (P < .05). There was a negative correlation (r=-.848) between the mothers' directiveness in the mother-child interaction and the child's self-regulation (P < .001).

The purpose of this study is to analyze the types of children's strategic thinking in the board games. Subject were 98 5-7-year-old children were participated in this study. Children divided by age were provided the same board game. Strategies used by the children to play the game were classified by age. The observational results were as follow; 1)Children used 9 strategies. Comparing to Kamii's study, children utilized 2 more strategic thinking. 2)Children used different game strategies based on children's age. Results showed that game strategies differentiated by child's age: five-year-olds used fewer strategies and older children applied a wider range of strategies.

The purpose of this study was to analyze the effect of home related variables like socio-demographic variables, parent-child communication, and concern for children's education on children's school adjustment. The data was collected from 287 elementary school children living in Gyunggido. Measurement scales included the children's school adjustment inventory, the questionnaire of the socio-demographic variables, the parent-child communication index, and the parent's concern about children's education index. Results showed that children's school adjustment was significantly effected with regard to: father's age, father's education, mother's education, income, and mother's job. Correlation analysis indicated that parent-child open communication was positively correlated to children's school adjustment; that is the relationships with teachers and with friends, study at school, and rule of school. As well, parent-child problematic communication was negatively correlated to all of the school adjustment variables. Parent's concern about children's education indicated positive correlations with all of the school adjustment variables. It was also found that: parent's concern about children's education, parent-child open communication, parent-child problematic communication, mother's education, and income were significant predictors of the children's school adjustment.

This study has a goal to read a trend of language research by analysing evaluation tools and methods that researchers have used for assessing young children's language abilities. Thus the study has chosen 237 language ability evaluation methods out of 121 young child's language ability evaluation researches. The treatises were selected from 4 types of early childhood education journals registered on the Korea Research Foundation. The data analysis was employed for processing the frequency and percentage of the collected data. The results were as follows: First, of single age groups the subject group most selected was five-year-olders and of mixed-age groups the subject group most selected was from three to five, and the number of subjects in researches were mostly below fifty children. The researches were sorted into an 'experimental/ investigational researching' type that has been frequently re-utilized by others, an 'interview type' using a data collection method, and a 'difference verification' type using a data analysis method which has been used in majority of studies. Second, the number of treaties that required data analysis has increased since 1996. Concludingly, the analysis of young child's language ability evaluation tools shows that the purposes of many researches were concentrated on studying children's knowledge about language, children's language functions such as speaking, reading, writing and listening, while evaluation contents were focused on speaking and writing.

With a purpose of investigating the current status of resource organization for infants and young children's resources, this study examined 8 municipal libraries in J city and suggested recommendations for improvements. To do that, interviews were conducted with 8 children's librarians and 25 users, who were parents visiting the libraries. All libraries examined were using KDC to classify young children's resources, but books were shelved by the alphabetic order of publishers' names. This arrangement strategy was regarded very convenient in re-shelving materials from the perspective of librarians, but users had difficulties in finding books because of the separation of the classification system and the arrangement system. Also, the online public cataloging system did not provide accurate and sufficient information to locate a book. Based on the results, this study suggested two ways for improvements: (1) classifying and arranging books by KDC, (2) developing a new classification system customized to infants and young children.
