Objective : The purpose of this study was to systematically review dysphagia rehabilitation treatment for children with feeding disorders. Methods : The articles evaluated in this study were collected from the PubMed, Medline Complete, and CINAHL databases and subsequently reviewed using the PRISMA flow chart and PICOS approach. A total of 13 papers were analyzed for study quality, disease groups, evaluation tools, interventions, and post-intervention effects. Results : Of the reviewed papers, six (46.15%) related to autism spectrum disorder (ASD) and seven (53.85%) to cerebral palsy (CP) with age ranges of between 2 and 8 years for the ASD studies and between 12 months and 18 years for CP. In evaluating the types of feeding disorder involved, the ASD group exhibited predominantly behavioral conditions while the CP subjects had a larger number of functional oral and swallowing issues. In terms of interventions, behavior modifications were used most frequently with ASD while oral-sensory motor, texture modifications, and electrical stimulation were applied at the same frequency with children with CP. All interventions were found to be effective. Conclusion : In this study, research into children with feeding disorders was reviewed according to condition, evaluation tool, and method of intervention. It is expected that this review can be used as basic data for developing a protocol that will allow clinicians to efficiently apply condition-specific interventions for eating disorders without resorting to trial and error.

Objective : The purpose of this study was to identify the status and trends of Korean child occupational therapy intervention studies according to the International Classification of Functioning, Disability, and Health, Children and Youth Version (ICF-CY). Methods : In this research, 47 studies on occupational therapy interventions for children that were published between January 2017 and December 2021 in the Journal of Occupational Therapy, registered in the Korea Citation Index, and analyzed the classification of the study type and evidence level to understand the trends. Moreover, intervention objectives and approaches were analyzed on the basis of the ICF-CY. Results : The outcomes of the analysis of the articles published in the Journal of Occupational Therapy were as follows: (1) Level IV was the highest evidence level (53.19%). (2) Among the studies, most (53.7%) included school-age children as subjects. Autism spectrum disorders and developmental delays were the most common diagnoses (14.8%). (3) As for the purpose of intervention according to ICF-CY, activity and participation factors were the most common (48.94%), and a sensory approach was frequently used. Conclusion : This study reviewed articles on occupational therapies for children that were published in the Journal of Occupational Therapy to understand the trends in occupational therapy interventions for children in South Korea. For the development of occupational therapies for children in the future, more qualitative research types and studies on various intervention approaches are needed.
Epidemiological studies suggest that maternal infection, maternal stress, and environmental risk factors during pregnancy increase the risk of brain development abnormalities associated with cognitive impairment in the offspring and increase susceptibility to schizophrenia and autism spectrum disorder. Several animal models have demonstrated that maternal immune activation (MIA) is sufficient to induce abnormal brain development and behavioral defects in the fetus. When polyinosine:polycytodylic acid (poly I:C) or lipopolysaccharide (LPS), which is commonly used in maternal immune activation animal models, was introduced into a pregnant dam, an increase in pro-inflammatory cytokines and microglial activity was observed in the offspring's brain. Microglia are brain-resident immune cells that play a mediating role in the central nervous system, and they are responsible for various functions, such as phagocytosis, synapse formation and branching, and angiogenesis. Several studies have reported that microglia are activated in MIA offspring and influence offspring behavior through interactions with various cytokines. In addition, it has been reported that they play an important role in brain circuits through interactions with neurons and astrocytes. However, there is controversy concerning whether microglia are essential to brain development or lead to behavioral defects, and the exact mechanism remains unknown. Therefore, for the potential diagnosis and treatment of brain developmental disorders, a functional study of microglia should be conducted using MIA animal models.
During pregnancy, maternal immune activation (MIA) from infection increases the risk of neurodevelopmental diseases, including schizophrenia and autism spectrum disorders. MIA induced by polyinosinic-polycytidylic acid (poly (I:C)) and lipopolysaccharide (LPS) in animal experiments has led to offspring with abnormal behaviors and brain development. In addition, it has recently been reported that microglia, which reside in the brain and function as immune cells, play an important role in behavioral abnormalities and brain development in MIA-induced offspring. However, the underlying mechanism remains unclear. In this study, we investigated whether microglia-specific inhibition of GPR56, a member of the G protein-coupled receptor (GPCR) family, causes behavioral abnormalities in brain development. First, MIA induction did not affect the microglia population, but when examining the expression of microglial GRP56 in MIA-induced fetuses, GPR56 expression was inhibited between embryonic days 14.5 (E14.5) and E18.5 regardless of sex. Furthermore, microglial GPR56-suppressed mice showed abnormal behaviors in the MIA-induced offspring, including sociability deficits, repetitive behavioral patterns, and increased anxiety levels. Although abnormal cortical development such as that in the MIA-induced offspring were not observed in the microglial GPR56-suppressed mice, their brain activity was observed through c-fos staining. These results suggest that microglia-specific GPR56 deficiency may cause abnormal behaviors and could be used as a biomarker for the diagnosis and/or as a therapeutic target of behavioral deficits in MIA offspring.

Objective : This study aims to verify the validity and reliability of the Korean version of the Sensory Processing and Self-Regulation Checklist (SPSRC) for children with and without autism spectrum disorder. Methods : The Pearson product-moment correlation coefficient was calculated using Short Sensory Profile (SSP) to verify concurrent validity. Construct validity was verified by comparing the sensory processing ability and self-regulation ability of the two groups. Cronbach's α was calculated in the case of internal consistency for reliability verification, and the test-retest reliability was verified through the Pearson correlation coefficient. Results : Based on the verification of the concurrent validity, the Korean version of SPSRC and SSP showed a statistically significant correlation (p < 0.01). The construct validity was found to have a statistically significant difference between the two groups in the area and sub-items of the Korean version of SPSRC (p < 0.001). For the internal consistency, Cronbach's α ranged from 0.700 to 0.975. The test-retest reliability showed that the correlation coefficient ranged from 0.937 to 0.997. Conclusion : The Korean version of SPSRC was confirmed to be an evaluation tool with high validity and reliability. It is expected to be used as an evaluation tool for planning treatment goals in clinical trials and as a meaningful basis for future research.

This study is a qualitative study conducted to analyze the functions and needs of social robots for parents of children with developmental disabilities in order to utilize care robots for treatment of children with developmental disabilities. The subjects of the study were 11 primary caregivers with children under the age of 18 whose children were diagnosed with developmental disabilities or who had been receiving special education for more than one year. The interview questionnaire was composed of a semi-structured questionnaire and consisted of awareness, necessity, expectation, concern, and other opinions about social robots. The interview was conducted as a non-face-to-face online video interview due to COVID 19. As a result of the study, 4 themes and 7 sub-topics were derived. The four topics were derived from the unfamiliar but soon-to-be-faced reality, social robots with active functions, opinions on the appearance and materials of social robots, and concerns about social robots. Through this study, it was possible to identify the expectations and suggestions of the main caregivers for social robots, which could not be identified in quantitative studies, and if these can be reflected in social robots to be developed in the future, it is expected that positive results with higher acceptance will be derived.

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.

Objectives : The purposes of this study were to examine the reliability and validity of the Korean version of Social Communication Questionnaire (K-SCQ) and to determine cut-off scores for diagnosis of autism spectrum disorder (ASD). Methods : A total of 166 subjects with ASD and their 186 unaffected siblings were recruited through child psychiatry clinics of university hospitals. Board certified child psychiatrists screened all probands suspected to have ASD based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition. To confirm the diagnoses, the Korean versions of the Autism Diagnostic Observation Schedule and the Autism Diagnostic Interview-Revised (K-ADI-R) were administered to all the subjects. All parents completed the K-SCQ and Social Responsiveness Scale (SRS). The non-ASD siblings were evaluated with the same instruments as the probands with ASD. We performed a factor analysis to examine the structure of K-SCQ. For testing the validity of K-SCQ, we compared the difference in Lifetime and Current scores of probands with ASD and their non-ASD siblings using t-test and analysis of covariance. Correlations between the K-SCQ and other measurements of ASD symptomatology, including K-ADI-R totals and domain scores and SRS, were examined. Receiver operation characteristic curve analysis was performed to extract cutoff scores discriminating affection status. Results : Four factors were extracted through factor analysis of K-SCQ ; 1) social relation and play, 2) stereotyped behavior, 3) social behavior, and 4) abnormal language. Cronbach's internal consistency was .95 in K-SCQ Lifetime, and .93 in K-SCQ Current. There were significant differences in total score of K-SCQ, both in Lifetime and Current between the ASD group and non-ASD siblings group (p<.05). K-SCQ scores were significantly correlated with K-ADI-R subdomain scores and SRS total scores (p<.05). The best-estimate cut-off scores of K-SCQ for diagnosis of ASD were 12 for 48 months and over, and 10 for below 47 months. Conclusion : Our findings suggest that the K-SCQ is a reliable and valid instrument for screening autistic symptoms in the Korean population. Lower cut-off scores than the original English version might be considered when using it as a screening instrument of ASD.

Objective : This study sought to systematically examine the intervention effect of social stories when applied in relation to children with sleep disorders. Methods : Studies available in the SCOPUS, ScienceDirect, PsycArticles, and PubMed databases that were published from 2001 to 2022 were searched. The keywords used for the search were as follows: ("social story" OR "social stories") AND ("sleep" OR "sleep disorders" OR "sleep wake disorder bedtimes" OR "sleep initiation and maintenance disorders" OR "sleep wake disorder" OR "sleep arousal disorders"). Based on the selection criteria, six experimental studies were selected and analyzed. Results : The selected studies were two randomized controlled trials, three individual trials, and one case study. The subjects were mostly children diagnosed with autism spectrum disorder who were school-aged or adolescent. The intervention types were often complex interventions, including social stories and other interventions, while the durations of the interventions varied from one day to more than 40 days. The interventions had a positive effect on the subjects' sleep quality, with night wakings, sleep onset delay, and sleep anxiety all being improved. As standardized assessment tools to evaluate the effectiveness of social stories, the Child Sleep Habits Questionnaire and the Child Behavior Checklist were used in two papers each, and were the most commonly used. As non-standardized assessment tools, each of the four papers used turbulence and sleep diaries as assessment tools. Conclusion : The effect of social story mediation can be divided into sleep quality and sleep-related behavior. In terms of sleep quality, studies showing improvements in night wakings, sleep onset delay, and sleep anxiety accounted for a large proportion of the sample. The detailed effect area of sleep quality showed a significant improvement after the interventions in most studies, and in all six studies analyzed in the present study, the continuation of the effect after the intervention was confirmed via follow-up tests. Thus, the findings of this study are expected to be helpful when applying social stories in children with sleep disorders in clinical practice due to presenting the intervention effects, outcome evaluation tools, and intervention periods in children with sleep disorders in prior investigations involving social stories.
