The purpose of this study is to examine the effects of a chorus program in a local child center regarding character, social skills, problematic behaviors, and ADHD. Subjects of this study included 24 children in elementary schools participating in the daytime programs at a local child center located in Suwon, South Korea. The chorus program was comprised of 12 sessions of 60 minutes each, conducted from April 5-July 5, 2017. Results of this study were as follows: First, during the interviews on the character of the children before and after participation in the chorus program, it was noted that the children became more active in terms of the relationships with others and leadership. However, it was also noted that children were more active at the center than they were at their schools. Second, the differences in social skills before and after the chorus program among children were significant in overall social skills and their sub-variables, indicating that there were effective in adjusting social skills. Third, the differences in problematic behaviors before and after participation in the chorus program were significant only in overall problematic behaviors and excessive behavior. This indicates that the program was effective in improving problematic behaviors, particularly for excessive behavior. Fourth, the differences before and after participation in the chorus program in terms of ADHD were statistically significant for ADHD and its sub-variables of carelessness and hyperactivity impulsiveness. This indicates that there was an overall improvement in attention deficit/hyperactivity disorder. Therefore, the findings in this study showed that the chorus program was effective on enhancing character, social skills, problematic behaviors, and ADHD behaviors.

Objectives : The aims of this study were to examine agreement between parent and teacher ratings of the Korean version Strengths and Difficulties Questionnaire (SDQ-Kr) for the children's psychopathology and to determine whether it is effective in diagnostics as the Korean version of Childhood Behavior Checklist (K-CBCL). Methods : SDQ-Kr and K-CBCL were completed by parents and teachers of 165 children aged 6-12 years. The clinical diagnosis was made by a child and adolescent psychiatrist who did not have knowledge of the outcome. Spearman's correlations were computed for associations between parents' and teachers' ratings on a subscale level. The Mann-Whitney U test was performed for the influence of child's age and sex on the results. Finally, AUC values were calculated for the diagnostic capacity and the difference between informants was tested using the z test. Results : High correlations were observed between parents' and teachers' SDQ-Kr on every scale. Parents were more sensitive to emotional symptoms of girls, while teachers appeared to be more responsive to externalized symptoms of boys, inattention-hyperactivity of young children, and emotional symptoms of seniors. Parents' SDQ-Kr demonstrated the highest prediction of attention-deficit hyperactivity disorder. Conclusion : Teachers' SDQ-Kr can be used in identification of child psychopathology when parents are absent or when their reliability is considered low.

Objectives : There have been very few studies on the compliance of methylphenidate-immediate releasing form(MPH-IR), which is the most frequently used drug in Korea, in Attention Deficit Hyperactivity Disorder(ADHD). This study was conducted to investigate the compliance rate and the related factors in the one year pharmacotherapy process via OPD for children with ADHD. Method : Total 100 ADHD patients were selected randomly among patients who have been treated with MPH-IR from September in 2002 to December in 2002. All the selected patients were diagnosed with DSM-IV-ADHD criteria and fulfilled the inclusion criteria. In March, 2003(at the time of 6 month treatment), all the patients and parents received the questionnaire for the compliance and satisfaction for MPH-IR treatment. In October 2003(at time of 1 year treatment), we, investigators evaluated the socio-demographic variables, developmental data, medical data, family data, comorbid disorders, treatment variables, and compliance rate. Through these very comprehensive data, The compliance rate at the time of mean 1 year treatment and the related factors were investigated. Result : 1) In the questionnaire for compliance and satisfaction for MPND treatment, the 60% of respondents(parents) reported more than moderate degree of satisfaction in the effectiveness of MPND. Their compliance rate for the morning prescription was 81%, but the rate of afternoon prescription was 43%. 2) In the evaluation at the time of 1 year treatment(October 2003), the 38% of parents were dropped out from the OPD treatment. The mean compliance rate for the 1 year treatment was 62%. the 38% of parents were dropped out from the OPD treatment. The mean compliance rate for the 1year treatment was 62%. 3) Compared with the noncompliant group(drop-out group), compliant group showed higher total, verbal and performance IQ scores. In the treatment variables, higher reposponder rate(clinician rating), higher medication dosage and more compliance rate in afternoon prescription were found in the compliant group compared with the noncompliant group. There were no statistical differences in the demographic variables(age, sex, SES, parental education level), medical data, developmental profiles and academic function. Conclusion : To our knowledge, this is the first report about the compliance rate of the MPH-IR treatment for the children with ADHD. The compliance rate at the time of mean 1year treatment was 62%, which was comparable with other studies performed in foreign countries, especially States. In this study, the compliance related factors were IQ score, clinical treatment response, dosage of MPH-IR, and early compliance for the afternoon prescription. These results suggest that clinician plan the strategies for the promotion of the early compliance for the after prescription and enhancement of overall treatment response.

Ovjectives: As the attention devoted to children's mental health increases, medical costs and burdens mount as well. In the present study, we evaluated the association between socioeconomic status(SES) and major child psychiatric symptoms. Methods: The subjects of this study were children of recruited from a mental health screening program in the Seoul Sungbuk mental health center over the course of 3 months. To establish the SES of each child, we collected data about each child's medical insurance, years of parental education, household income, family structure and housing. 149 children & parents completed questionnaires including the Childhood Depression Inventory(CDI) and the Korean Attention Deficit Hyperactivity Disorder Rating Scale(K-ARS). Results: The mean K-ARS-P score was $12.1{\pm}11.1$ and the suspected prevalence of ADHD was 20.8%(n=31). The mean cm score was $12.9{\pm}7.9$, and the prevalence of suspected depression was 16.8%(25). Depressive symptoms and ADHD symptoms were both more severe than those observed in a previous epidemiologic study in Korea. Depressive symptoms were more closely associated with family SES status. Conclusion: SES status is one of the most important risk factors in the development of major child psychiatric symptoms. In our study we found that depressive symptoms in particular were most tightly associated with psychosocial factors. Evaluation of the risk factors, early screening and intervention for low SES children would be valuable mental health management tactics to implement in a community mental health system.

Background: There is increasing concern that moderate preterm (32-33 weeks' gestation) and late preterm (34-36 weeks' gestation) birth may be associated with minor neurodevelopmental problems affecting poor school performance. Purpose: We explored the cognitive function, cognitive visual function, executive function, and behavioral problems at school age in moderate to late preterm infants. Methods: Children aged 7-10 years who were born at 32⁺⁰ to 36⁺⁶ weeks of gestation and admitted to the neonatal intensive care unit from August 2006 to July 2011 at the National Health Insurance Service Ilsan Hospital were included. We excluded children with severe neurologic impairments, congenital malformations, or chromosomal abnormalities. Neuropsychological assessments consisted of 5 neuropsychological tests and 3 questionnaires. Results: A total of 37 children (mean age, 9.1±1.2 years) participated. The mean gestational age at birth was 34.6±7.5 weeks, while the mean birth weight was 2,229.2±472.8 g. The mean full-scale intelligence quotient was 92.89±11.90; 24.3% scored between 70 and 85 (borderline intelligence functioning). An abnormal score was noted for at least one of the variables on the attention deficit hyperactivity disorder diagnostic system for 65% of the children. Scores below borderline function for executive quotient and memory quotient were 32.4% and 24.3%, respectively. Borderline or clinically relevant internalizing problems were noted in 13.5% on the Child Behavior Check List. There were no significant associations between perinatal factors or socioeconomic status and cognitive, visual perception, executive function, or behavior outcomes. Conclusion: Moderate to late preterm infants are at risk of developing borderline intelligence functioning and attention problems at early school age. Cognitive and executive functions that are important for academic performance must be carefully monitored and continuously followed up in moderate to late preterm infants.

Phenomenology has been developed by philosophers like Kant and Husserl since the late 18th century. Jaspers, a German psychiatrist, adopted it into psychopathology studies and accumulated data by closely observing and recording the patients' symptoms and signs. Among descriptions done even before the psychopathology or diagnostic criteria of disorders in the field of child psychiatry was established, we can find exact and valuable descriptions matching the autism spectrum disorder or attention deficit/hyperactivity disorder. The diagnostic criteria of modern childhood psychiatric disorders were established based on these grounds. Phenomenological/descriptive methods in various psychiatric fields lead to medical study methods for social phenomenon such as oiettolie, hikikomori, and internet game addiction. Since Romanian orphans were adopted to the western world, descriptive studies along with neurobiological studies on the influence of stimulus deprivation on emotional and physical development are being conducted. While phenomenology, which was adopted by Jaspers to verify psychopathology, was developed mainly by observation and description, recent studies are explaining such descriptive phenomena even at the synapse level due to advances in neurobiology. Although phenomenological/descriptive psychiatry, describing precise and detailed experiences of patients, is less applied nowadays among modern study methods, we must remember that such descriptions may lead to biological studies and provide evidence to improve the accuracy of choosing and applying treatment methods.

The pathophysiology and neural mechanism involved in Tourette's and chronic motor tic disorder are highly controversial. In order to investigate the functional abnormalities of brain. In Tourette's and chronic motor tic disorder, 42 children with Tourette's and chronic motor disorder underwent single photon emission computed tomography(SPECT) using Tc-99m-HM-PAO. The results are summarized as follows : 1) 31.0% (13/42) of this series revealed perfusion defect in cerebral cortex. 2) 4.8% (2/42) revealed perfusion defect in basal ganglia. 3) 4.8(2/42) revealed perfusion defect in thalamus. 4) 16.7%(7/42) showed perfusion defect in cerebellum. 5) The frequency of abnormal perfusion showed no significant difference between tic with and without attention deficit hyperactivity disorder. 6) The frequency of abnormal perfusion showed no significant difference between Tourette's and chronic motor tic disorder. These findings support the hypothesis of a possible involvement of brain dysfunction in the production of Tourette's and chronic motor tic disorder, and quantification of blood flow and co-registration with magnetic resonance imaging will increase the validity of this study.

Background: Injury is the leading cause of death or disability in children and adolescents. Rates of deaths from injuries have recently declined, but studies of the occurrence of nonfatal injuries are lacking. Purpose: This study aimed to investigate nonfatal injuries in children and adolescents younger than 20 years based on data from the Korean National Health and Nutrition Survey, 2007-2018. Methods: A questionnaire survey was conducted to determine whether children and adolescents had experienced an injury requiring a hospital visit in the previous year. We investigated each injury's risk factors and characteristics. Results: Of a total of 21,598 children and adolescents, 1,748 (weighted percentage, 8.1%) experienced one or more injuries in the previous year. There was no yearly difference in the proportion of injuries experienced. Among the male subjects, 10.0% had an injury experience; among the female participants, 6.1% had an injury experience (P<0.001). The highest rate was 9.0% in children aged 1-4 years. In multivariate logistic regression analysis, male sex; having an urban residence; having restricted activity due to visual, hearing, or developmental impairment; and attention deficit/hyperactivity disorder were significant risk factors for injury experience. The characteristics of up to 3 injuries per patient were investigated, and 1,951 injuries were analyzed. Falls and slips accounted for 34.9%, collisions for 34.1%, and motor vehicle accidents for 11.3% of the total injuries. Ninety-six percent of injuries were unintentional, 20% caused school absences, and 10% required hospitalization. Conclusion: Among Korean children and adolescents, 8.1% experienced injuries at least once a year with no significant differences in incidence over the past 12 years. Greater attention and effort to prevent injuries are needed.

Objective : The purpose of this study was obtaining data on the efficacy and safety of risperidone in child and adolescent psychiatric patients. Method : Thirty one children and adolescents (males n=18, females n=13, age ranged from 5.4 to 17.3 years) treated with risperidone were selected among child and adolescent psychiatric inpatients of Seoul National University Hospital from January, 2001 to June, 2002, and charts for them were reviewed retrospectively. Results : The primary psychiatric disorders treated with risperidone were schizophrenia and other psychosis, bipolar I disorder with psychotic features, Tourette's disorder, autism spectrum disorders, mixed receptive and expressive language disorder, attention deficit-hyperactivity disorder, conduct disorder and obsessive-compulsive disorder. twelve of these had comorbid mental retardation. Primary target symptoms of risperidone were psychotic symptoms (n=13 or $41.9\%$), behavioral symptoms (n=10 or $32.3\%$) including aggression, impulsivity, hyperactivity, stereotypy nonresponsive to other psychiatric treatments, and chronic and severe tics (n=8, $25.8\%$). The efficacy of risperidone was measured by clinical global improvement (CGI) for target symptoms, $67.7\%$ of subjects showed moderate or marked improvements and its therapeutic effect appeared to be maintained during at least 7.5 months. Mean daily dosage of risperidone was $0.05{\pm}0.01mg/kg$, the group with psychotic symptoms had significantly higher mean daily dosage (0.07mg/kg) compared with other two groups (0.04mg/kg) with behavioral symptoms or tics. A variety of adverse events were reported in this study : weight gain (n=23) most commonly reported, extrapyramidal symptoms (n=15), autonomic symptoms (n=6), sedation (n=5) and symptoms related to hyperprolactinemia (n=2) etc. Although there was no drug change related to the adverse events of risperidone, and $90\%$ of subjects at their last visits were maintained on it, thus its tolerability appeared good. Conclusions Results suggest that risperidone may be relatively safe and effective drug in managing a wide variety of child and adolescent psychopathologies such as psychotic symptoms, behavioral symptoms including aggression, impulsivity, hyperactivity and stereotypy nonresponsive to other psychiatric treatments, and chronic and severe tics. Controlled and long-term studies of efficacy and safety of risperidone treatment for children and adolescents are recommended in the future.

Although Attention Deficit Hyperactivity Disorder(ADHD) has been considered as the disorder occurring during childhood, the prevalence is increasing among adolescents and adults. The prevalence rate varies from 2.0 to 14.3% due to the difference of diagnostic criteria, different assessment methods, or subjects' age difference. Therefore, it needs to make age specific(i.e., for children, for adolescents, and for adults) assessment tools. Authors translated Conners-Wells Adolescents Self-Report Scales(short form)[CASS(S)] in to Korean to get validity and reliability as a way of development of assessment tool for adolescent with ADHD in Korea. CASS(S) was translated and corrtected by three psychiatrists and one clinical psychologist. To examine the concurrent validity and test-retest validity, CASS(S) was applied with K-YSR on one class of each grade in a middle school in Seoul with two week interval(total 115：male 58, female 57). To test validity, authors analysed and got Cronbach's as internal consistency. Construct validity was done by principal axis factor analysis on 4,354 students. As a result, Cronbach's alpha for internal consistency was .88, Pearson coefficient for test-retest reliability .83, and coefficient for concurrent validity .65. And in the factor analysis to examine construct validity, three factors were revealed as cognition, hyperactivity, and conduct. These results shows that CASS(S) may be useful tool for adolescents with ADHD, although there was a limit not to be done the comparison with clinical groups.
