This study examined gender differences of the effect of playfulness on the social skills of young children. The subjects were 242 4- to 6-year-old children at five nursery schools and kindergartens. Results showed that playfulness influenced social skills of young children. In particular, young children's playfulness was a more effective variable of assertion than self-control, cooperation and responsibility. Cognitive spontaneity and social spontaneity were the most effective variable of social skills. Playfulness had variable influences on social skills by gender: Among boys, playfulness was a less effective variable of cooperation than the other variables of social skills. Among girls, playfulness was a less effective variable of self-control than other variables of social skills.

Purpose: We evaluated the long-term results of endoscopic Deflux$^{(R)}$ injection for treating vesicoureteral reflux (VUR) in children. Methods: Between September 2004 and September 2014, 243 children (137 boys and 106 girls) with a mean age of 53 months underwent Deflux$^{(R)}$ injection. Our clinical protocol included radionuclide voiding cystography (RNC) at postoperative 3 months, 1 year and 3 years to assess the VUR resolution. Results: The cure rates at 3 months, 1 year, and 3 years by patients were 70.8%, 64.3%, and 65.6% for the total patients and 79.2%, 75.2%, and 76.4%, for the ureters, respectively. The recurrence rate of postoperative febrile urinary tract infection (UTI) was 20% in patients without VUR at postoperative 1 year. Twenty patients undergoing ureteroneocystostomy (UNC) significantly had younger age (P=0.003), higher VUR grade (P<0.001), and lower success rates of Deflux$^{(R)}$ injection (P<0.05). On univariate analysis, older age (P=0.014) and lower grade of VUR (P=0.031) were the significant predictors of a successful outcome. But there was none on multivariate analysis. Younger age, especially age of 0-12 month-old, was the only significant predictor of postoperative febrile UTI recurrence on both univariate and multivariate analysis. Conclusion: Deflux$^{(R)}$ injection is efficacious with a low complication rate for the anti-reflux procedure in children. There is low recurrence rate of UTI though VUR persists, and high probability of no VUR at 3 years if no VUR at 1 year. It is recommendable not to perform follow-up RNC at 3 years routinely if no VUR at 1 year.

The purpose of this study was to describe and understand the characteristics of morphological, contextual as relational aggression among 4-year old children during free play periods. The ethnographic methods included participants observation of children's play interaction behaviors, field notes, video taping and analysis of transcribed date. The results are as exclusion occurred by group power taking the relational attribute, including direct language, while the other would not be revealed easily other than being in line with real relation. Also as follows; proactive relational aggression was more frequently observed in girls, and their major strategies employed against someone they disliked were ignoring them, distorting play-rules, and so on. Major strategies of reactive relational aggression in girls were largely manipulative in nature, for example, 'threatrning their friend' and 'withdrawal of friendship'.

The purpose of the present research was to study the self-regulation of the child during mother child interaction. That is. this study focused on how mothers regulated children's problem solving efforts before children began to function as independent agents capable of self-regulation. The emphasis was on the "regulation-by-others" that preceded "self-regulation". The subjects of this study were 30 mother-child dyads. The dyads were divided into 3 groups of 10 dyads each on the basis of the child's age (2, 3, and 4 years of age). The instrument used for this study was the "truck puzzle" devised by Wertsch, McNamee, Mclane and Budwig (1980). The problem solving task in this study required the dyad to make a puzzle in accordance with the model puzzle. The interaction of 30 mother-child dyads was observed and analyzed flH verbal and non-verbal behavior used by the mother to regulate the child's behavior. One-way ANOVA, Scheffe post hoc comparision and Spearman's rank-difference correlation were used for the statistical analysis of the data. The results revealed that there were significant age trends in regulation-by-others and self regulation in joint cognitive activity; that is, there were developmental transitions from regulation by-others to self-regulation in connection with crucial strategic behavior (looking at the model). Significant differences were found in mothers' interventions after children's gaze at the model in joint cognitive activity; that is, the mean proportion of mothers' intervention for the 2-year-old group was the highest and that of the 4-year-old group was the lowest. There were no significant age-related differences in mothers' use of referential perspectives in joint cognitive activity. Children's regulation- by-others increased and children's self-regulation decreased in proportion to mothers' use of referential perspectives.

Background: Delivery of Bacille Calmette-Gur$\acute{e}$in (BCG) Tokyo vaccine, with the multipuncture device, has been much preferred over BCG Pasteur, with the intradermal method, possibly due to the easier manner of administration, a desire to avoid any trouble with scars, as well as side effects and higher profits to providers in South Korea. Methods: To determine BCG scar status in 0~6 year old children vaccinated with two BCG vaccines (Pasteur BCG vaccine with intradermal method and BCG Tokyo vaccine with percutaneous method), the data from the national BCG scar survey in 2006 was analyzed. Results: Based on the national survey, the high proportion that were vaccinated with BCG Tokyo vaccines with the multipuncture method (64.5%) was noted in 0~6 year old Korean children. From inspection of scar formation, as an indicator of vaccination, the median number of the visible pin scars from the percutaneous method was 16 (interquartile range, 12~18) in the Korean children, and pin scars decreased as the age of the children increased (p<0.001). Conclusion: The findings in this survey clearly showed a growing preference of parents for the BCG Tokyo vaccines by the multipuncture method in South Korea.

The incidence of Meckel's diverticulum(MD) in general population has been assessed as 2 percent. The major complications of MD are bleeding, perforation, and intestinal obstruction. In spite that the complication rate of Meckel's diverticulum is relatively high(about 4.2% during a lifetime), the preoperative diagnostic rate of complicated MD is very low. Authors investigated the clinical characteristics of complicated MD to improve the diagnostic rate. 16 patients with complicated Meckel's diverticulum who were operated upon at the Department of Pediatric Surgery, Seoul National University Children's Hospital from June 1985 to December 1993 were reviewed. Among the 16 patients with complicated MD, 12 patients(75%) were under 2 year-old and male were predominant(88%). The most common complication was bleeding patients with bleeding MD (8 cases) were diagnosed preoperatively as MD. 8 patients with other complications(perforation : 4 cases, obstruction : 4 cases) could not be suspected as complicated MD except one patient who had previous history of melena. These patients were diagnosed after exploratory laparotomy under the various impression other than MD. Among 12 patients with ulcer related complications such as bleeding and perforation, heterotopic gastric mucosa was found in 11 patients. In conclusion, in any children with unexplained acute abdomen, especially under 2 years old, complicated MD must be included in differential diagnosis. In children with obscure lower gastrointestinal bleeding, $^{99m}Tc$-pertechnetate scintigraphy is a useful diagnostic tool to rule out bleeding MD.

Causal relationships of kindergarteners' phonological awareness and processing to their ability to read words was investigated with the participation of 289 4- to 6-year-old children attending three kindergartens in Busan. Results showed gradual growth in reading ability with age. Children performed best in reading words and poorest in reading low frequency letters. They showed continuous development in skills of syllable deletion, phoneme substitution, phoneme insertion, phonological memory and naming. Discontinuous development was found in counting syllables. Longer syllables were difficult to count, and middle syllables of 3 syllable words were hard to delete. Children had poor perception of final consonants of Consonant-Vowel-Consonant syllables. Children's phonological awareness and processing were latent variables strongly related to ability to read words written in Hangul.
