Early detection and intervention is critical in improving prognosis of developmental disorders. Developmental delay can have many different causes and the clinical features of developmental delay are diverse according to its etiologic causes and severity. The vast and rapid growth of the child's neurobehavioral repertoire from birth through adolescence requires the physician's abundant experience, knowledge, and understanding of development. Here, we summarize instruments for use in neurodevelopmental assessment of infants and toddlers, focusing on motor development, which is the most frequent complaint listed in the developmental clinic.

The preliminary Korean Paternal Involvement Scale of 84 items was constructed from items collected from free-response surveys with 106 middle school students and 33 fathers followed by consultation with experts. Those items were tested on a sample of 339 middle school students. The 82 items selected through item analysis were analyzed by factor analysis. Of these, 54 items were categorized into seven factors : leisure-life, proffering information, discipline, academic support, tradition-inheritance, material support, and everyday life. Leisure-life, proffering information, and academic support correlated with grade level of adolescents and fathers' education. The alpha coefficients of this scale ranged from .68 to .90.

The developmental self-knowledge from preschool to early adolescence was studied from a cognitive-structural perspective. Responses of the subjects to the question "Who am I?" were analyzed by means of a 29-category scoring system. The question was administered to 250 boys and 229 girls from kindergartens, elementary schools and middle schools in Seoul. One way-ANOVA and Duncan test were utilized for the statistical analysis. The major findings of the present study showed that with increasing age there was (1) a significant increase and diversification of self-knowledge. (2) an individual's self-knowledge became more abstract and less concrete, and (3) self-descriptions shifted from the physical to the psychological self.

This study examined patterns of delinquent behavior trajectory from late childhood to early adolescence and examined relationships between patterns of trajectory and individual, family, and school factors. Youth delinquent behavior trajectories were examined by mixed growth models using data from the 2nd to 5th year surveys of the Seoul Panel Study of Children. Relationships between patterns and effect factors were examined by multinominal logit models. Four patterns emerged: non-delinquency (80%); rapidly accelerating delinquency (3.3%); decelerating delinquency (6.0%); and moderately accelerating (10.7%) groups. Contacts with a delinquent peer group had persistent effects on more serious delinquent behavior trajectories. Increased levels of self-esteem and school achievement prevented increase in delinquent behaviors; close relationships with parents and parental supervision caused decrease in delinquent behaviors.

The prevalence of childhood obesity is increasing worldwide at an alarming rate. While obesity is known to increase a variety of cardiovascular and metabolic diseases, it also acts as a risk factor for the development and progression of chronic kidney disease (CKD). During childhood and adolescence, severe obesity is associated with an increased prevalence and incidence of the early stages of kidney disease. Importantly, children born to obese mothers are also at increased risk of developing obesity and CKD later in life. The potential mechanisms underlying the association between obesity and CKD include hemodynamic factors, metabolic effects, and lipid nephrotoxicity. Weight reduction via increased physical activity, caloric restriction, treatment with angiotensin-converting enzyme inhibitors, and judicious bariatric surgery can be used to control obesity and obesity-related kidney disease. Preventive strategies to halt the obesity epidemic in the healthcare community are needed to reduce the widespread deleterious consequences of obesity including CKD development and progression.

Functional aphonia is a disease in which normal vocal ability is suddenly lost. When voice therapy is started at an early stage, the prognosis is good. However, if the functional aphonia persists for a long time, there is a possibility that the voice disorder may become fixed, though reports of these characteristics are rare. The authors experienced a patient with functional aphonia that occurred in adolescence and lasted for 7 months and reported the result of treatment.

Purpose: This study was done to identify the effects of the Positive Peer Relationship Training Program on self-esteem, bullying, and depression. Methods: The research design was a quasi-experimental research with a nonequivalent control group non-synchronized pre-posttest. The recruited participants were forty-four 6th graders at an elementary school in G city. The research was carried out from September 10 to November 19, 2012. To test the effects of the Positive Peer Relationship Training Program, the participants were divided into two groups, an experimental group (23) and a control group (21). The Positive Peer Relationship Training Program was provided to the experiment group for 45 minutes/session twice a week, for 4 weeks. Data were analyzed using Fisher's exact probability test, $x^2$-test and t-test with the SPSS/WIN 18.0 program. Results: After attending the Positive Peer Relationship Training Program, no significant differences were found in self-esteem scores but significant differences were found in bullying and depression scores between the experimental group and the control group (t=1.27, p=.212, t=-2.10, p=.042; t=-2.37, p=.023). Conclusion: The results indicate that the Positive Peer Relationship Training Program is an effective nursing intervention for decreasing bullying and depression among Children in Early Adolescence.

The main purpose of this study is to examine the effects of the fathering practice on children's sociality. The subjects of this research are 569 (grade 6) students who are from 4 elementary schools, and 511 (grade 3) students who are from 4 other middle schools in Seoul and Gyeonggi province. The data was collected using two kinds of questionnaires: Canfield's (1995) Fathering Practice Scale and Urn Guy-Sung's (1999) Children's Sociality Scale. The data was analyzed by frequency, mean, standard deviation, percentage, Cronbach's alpha, t-test, one-way ANOVA, Scheffe's post hoc test, and hierarchical regression. The major results of this research are summarized as follows: First, there were differences in children's sociality according to children's and fathers' perceptions of the fathering practices. I classified 1080 students into 4 groups by mean${\pm}$1/2standard deviation of the children's and fathers' perceptions of the fathering practices. The results showed that children's sociality tends to be higher when the children's perceptions of the fathering practice are at a high level (Group 1 and Group 2), compared to when the fathers' perceptions of the fathering practice are at a high level (Group 3 and Group 4). Second, hierarchical regression was divided into two models so as to know how the effects were different from the children's and fathers' perceptions of the fathering practice on children's sociality. In the first model, only the fathers' variables were inputted and fathers' perceptions on fathering practice has significant effects on children's sociality. In the second model, both the children and fathers' variables were inputted into analysis. The fathers' perceptions of the fathering practice were not influenced, but children's perceptions of the fathering practice had great effects on children's sociality. Third, as the result of hierarchical regression with age, mid-childhood has significant effects on children's perceptions of the fathering practice on children's sociality. In addition, early adolescence is an important variable in the effects of the fathers' perceptions of the fathering practice on children's sociality. As a result the fathers' perceptions of the fathering practice are important and influential variables on children's sociality. In the result of this study fathering practice is necessary in children's development.

Anger is a multi-dimensional concept ranging from feeling irritable to violent aggression. A growing body of literature suggests the relevance of sleep in regard to anger. The current study aims to review previous studies on the association between anger and diverse aspects of sleep including sleep disruption, chronotype, sleep disorders and sleep deprivation. An association between sleep and anger has been observed starting in the early stage of life, with sleep of infants or toddlers affecting emotional and behavioral aspects of anger. However, the association between anger and sleep is not clear in adolescents and might be due to the effects of psychosocial factors on both sleep and anger during adolescence. Subjective but not objective sleep disturbances of adults have been also associated with anger. Evening types showed more anger, which might be mediated by psychological characteristics or social jet lag of evening people. Increased anger has also been found in those with insomnia, sleep apnea, or experimental sleep-deprivation. Previous studies have reported that diverse sleep disturbances are related to anger. Future study assessing the various sleep or circadian indices and considering the multidimensional aspects of anger are needed.
