The purpose of this study is to examine the effect of parents knowledge on oral health status toward their children. This study was carried out to investigate and analyze the cognitive degree of dental subjects and general public who have an experience to be treated for their dental knowledge, operative dentistry, and dental prothesis in the oral health care through the questionnaires. The results are as follows : 1 : In questioning the frequency in the visitation of dental clinic, 68.8% usually go to see dentists, if children's teeth have trouble. It was the reason that economical standard and educational level were enhanced as before. 57.6% took a kind of medical measures. 2 : In surveying the preference of dentists’ age or gender, 56.9% preferred younger dentists to older or female dentists. On the contrary, 56.9% children want younger dentists, and 64.8% children want female dentist doctor. As a conclusion, the preference of dentists’ age or gender is relevant with a view to remove big horror, which can be evoked by dental measures. 3 : In questioning the possession amount of decayed teeth, 45.8% have more than four. Usually those parents who have children filled their decayed teeth with artificial or installed with dental prosthesis. As a conclusion, age is relevant in this study in p<0.05 level. 4 : In asking for efficient starting-year of tooth brushing, 42.6% said that 2 or 3 year age is the most efficient, and especially 80.6% teach children to learn brushing themselves. (P<0.05). As a conclusion, the voluntary brushing can be good behaviour for good dental health. 5 : In surveying the way they obtained dental information, 38.9% were given form mass media, but 90% were once not delivered with the education of dental health. Because parents have been known narrow and deficient information of dental health through mass media, experts in dental health have to deliver help their parents to be delivered with systematical dental information. The conclusion of this study can be summarized that parents' role is very important to their children's tooth health and the education program for systematical dental information should be delivered to their parents.

Prior studies were limited in the comparison of false belief tasks with desire tasks due to lack of consideration of level of executive functions. To compensate for this, executive functions were included in new preference-related and game-related tasks of conflicting desire. These tasks were administered to 246 preschoolers ranging from 2.5 to 4 years of age. Statistical analysis was by one-way ANOVA and repeated measures ANOVA. Results showed significant main effects depending on age and task type. Younger children lacked ability of executive function, such as inhibition and working memory. Older preschoolers averaged better scores on task performance, showing that it is difficult for younger children to control their own desires and select the contradicted view.

This study investigated the development of complex sentences in the early utterances of Korean-Chinese children. The subjects were 47(20 2-year-old, 15 3-year-old, and 12 4-year-old) Korean-Chinese children living in China. Each child's spontaneous natural speech during interaction with his/her caregiver was videotaped for about 30 minutes and analyzed for Korean complex sentences using Kim's(2000) categories and Korean Computerized Language Analysis 2.0(2000). Results showed that older children were higher in Mean Length of Utterance and in number and frequency of word types than younger children. The language development of bilingual children was delayed compared with monolingual children but the developmental sequence between bilingual and monolingual children was similar.

Relationships between parents' home literacy attitudes in low-income families and children's emergent literacy were studied with 107 children 4- and 5-years of age and their parents. Instruments were Kim and Kwon's (2006) questionnaire about parents' literacy attitudes, the Peabody Picture Vocabulary Test-Revised(Kim et al., 1995) and the Concepts About Print(CAP; Kim & Kim, 2004). Results showed that parents of younger children were positive about reading books; parents of older children were positive about reading instruction. More positive parental feelings about reading and higher frequencies of reading with the child were related to children's higher vocabulary scores. Children's CAP was positively related with amount of parents' reading instruction, home literacy resources, and number of child's books in the home.

The purpose of this study was to assess children's literacy in Korea. The subjects were 147 children aged 3 to 5 in Iksan and Chonju. For the assessment of children's literacy, the revised form of WLAT(Written Language Awareness Test) (Taylor & Blum, 1980) and "The Concept About Books Interview" designed for this study were used. The test scores and oral responses of the children were analyzed by frequencies, means, ${\chi}^2$ test, one-way ANOVA, Pearson's r, and $Scheff{\acute{e}}$-test. The findings Showed that : (1) the children had more awareness about the mapping principles between speech and print, and the context of sentence than about technical aspects of the written language, and (2) the children had a low awareness of the ultimate function of books. Younger children recognized a hook as a play instrument, whereas older ones saw it as a decoding instrument.

This study examined effects on children's emotional expressiveness and regulation strategies or maternal attitudes and emotional expressiveness. Participants were 180 children(88 girls) age 3-5, their mothers, and 20 teachers. Results showed boys used more aggressive and girls used more positive coping strategies. Younger children used more aggressive and non-expressive strategies. When mothers had more Permissive and Accepting attitudes, children used more positive coping strategies. When mothers had more Restrictive or Controlling attitudes, children used more aggressive strategies. When mothers expressed positive emotions, children used fewer aggressive and venting strategies. When mothers expressed negative emotions, children used more aggressive and fewer positive coping and non-expressive strategies. Negative maternal emotional expressiveness was an especially influential factor on children's emotional regulation strategies.

Griscelli syndrome type 2 (GS2) is a rare autosomal recessive disease caused by mutations in the RAB27A gene. It is characterized by cutaneous hypopigmentation, immunodeficiency, and hemophagocytic lymphohistiocytosis. We describe 2 brothers who had GS2 with clinically diverse manifestations. The elder brother presented with a purely neurological picture, whereas the younger one presented with fever, pancytopenia, hepatosplenomegaly, and erythema nodosum. Considering that cutaneous hypopigmentation was a common feature between the brothers, genetic analysis for Griscelli syndrome was performed. As the elder sibling had died, mutation analysis was only performed on the younger sibling, which revealed a novel homozygous mutation in the RAB27A gene on chromosome 15 showing a single-base substitution (c.136T>A p.F46I). Both parents were heterozygous for the same mutation. This confirmed the diagnosis of GS2 in the accelerated phase in both siblings. The atypical features of GS2 in these cases are a novel mutation, isolated neurological involvement in one sibling, association with erythema nodosum, and 2 distinct clinical presentations in siblings with the same genetic mutation.

This study aims to examine how home child care allowance influences a mother's choice of child care type. To accomplish this goal, we surveyed 432 mothers who had at least one child under 5 years old. The data were analyzed by frequencies, percentages, means and binomial logistic regressions. The results showed that unemployed mothers and mothers with younger children had a high tendency to choose home child care allowance instead of child care subsidy. Second, mother's employment status, age of first child and an interactive term of mother's employment status and home child care receipt influenced a concordance between an ideal and actual child care type. Unemployed mothers and mothers with younger children were more likely to experience a concordance between their ideal and actual types of child care. By investigating how home child care allowance affects the right of choice in child care type, this study provides empirical information to policy makers and researchers and contributes to develop cash-benefit policies for families with young children.

Objectives: Child and adolescent sleep is an important factor for brain and physical development. Therefore, it is necessary to investigate the prevalence of sleep disorders and nonorganic sleep disorders in children and adolescents and determine the type of utilization of medical institutions. This study analyzed the prevalence and type of medical institutions in Korean children and adolescents with sleep disorders and nonorganic sleep disorders. Methods: This study used data recorded in the Health Insurance Review and Assessment-National Patient Sample (HIRA-NPS) database from 2010 to 2017. Details of medical institution type and patient's sex, age, and treatment type were extracted for patients younger than 20 years with sleep disorders and nonorganic sleep disorders. Results: Among 2,536,478 patients under age 20, we identified 3,772 patients with sleep disorders or nonorganic sleep disorders. From 2010 to 2017, the prevalence of sleep disorders in children and adolescents was 0.07% to 0.09%. The utilization rate of Korean medical institutions was 30.47%. The prevalence of nonorganic sleep disorders and the utilization rate of Korean medical institutions were 0.06% to 0.08% and 45.99%, respectively. Conclusion: The prevalence of sleep disorders and nonorganic sleep disorders in the under-20 population was 0.14% to 0.16%. More than 70% of patients with nonorganic sleep disorder who were younger than 9 years used Korean medical institutions.

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.
