Objective : This systematic review aimed to evaluate the global literature on the effect of early intervention for preschool children with autism spectrum disorder (ASD). Methods : A literature search of the PubMed database identified 10 studies published up to December 2017, using the following search terms: autism, autism spectrum disorder, ASD, high-function autism, high-function ASD, Asperger syndrome, pervasive developmental disorder, PDDNOS, intervention, and early intervention. Results : Early intervention for children with ASD used Applied Behavior Analysis in 8 of the 10 selected studies. The other two studies used a Sensory Integration approach and Technology-based intervention. Most studies reported positive effects on communication skills, social interaction skills, intelligence, adaptive behavior, and improved attention through early intervention. Conclusions : These results suggested a basis for early intervention for children with ASD. Further research is needed to determine the effectiveness of early intervention.

Objectives: Early intensive interventions are very important for children with autism spectrum disorder. We examined the actual conditions of hospital-based early intensive interventions for autism spectrum disorder in Seoul, in order to help develop and implement an evidence-based early intensive intervention model for use in Korea. Methods: Nine hospital-based institutes running an early intensive intervention program for children with autism spectrum disorder responded to a questionnaire in September 2014. They provided a brief introduction to their program, explained its theoretical bases, and reported the number of children, their age, intervention time, duration and so on. Results: In the majority of the institutions, the intervention was provided for over 20 hours every week, and the theoretical bases included various applied behavioral analysis (ABA) methods and other therapies (language and occupational therapy). The therapist-child ratio ranged from 1:1 to 5:3. Various types of therapists were involved, including behavioral analysts, special education teachers and (or) language pathologists. There was only one clinic where the behavioral analyst was the main therapist. Usually, the intervention was terminated just before the child entered elementary school. The main merit of the hospital-based intervention in our survey was the effectiveness of the multi-disciplinary intervention plan and its other merits were the accuracy of the diagnosis, its ability to be combined with medicine, and so on. Conclusion: The current hospital-based early intensive intervention programs provide interventions for over 20 hours per week and employ multidisciplinary approaches. However, there are very few institutes for children with autism and very few intervention specialists and specialist education courses in the country. We need more educational programs for intervention therapists and have to try to develop policies which encourage the implementation of an evidence-based early intensive intervention program nationwide.

The significant role of joint attention in the development of children with autism spectrum disorder (ASD) has highlighted the importance of early intervention. With the emphasis on the effective cueing and reinforcer for orienting to social stimuli in improving responding to joint attention (RJA) of children with ASD, the use of musical cue was hypothesized. This study aimed to examine the occurrence of RJA behaviors depending on the attentional cue, which differed in the level of information and type of auditory modality. Nine children with ASD participated in this study. The use of eight different joint attention cues were analyzed in terms of the frequency and accuracy of RJA behaviors elicited. The results of the study showed that RJA behaviors occurred more frequently with musical cues than with verbal cues and the mean accuracy rate of RJA was higher with musical cues (p = .047). Musically delivered eliciting and directing cues accompanied with pointing elicited the highest attentional shift and RJA accuracy. The significant increases in RJA with the use of musical cues indicated that incorporating musical elements into an attentional cue may provide more accurate cue information, enough to improve RJA behaviors of children with autism.

Purpose : Early detection and intervention of hearing impairment is believed to improve speech and language development and behavior of children. The aim of this preliminary study was to determine the prevalence of hearing impairments, and to identify the association of risk factors relating to refer response in high risk neonates who were screened using distortion product otoacoustic emissions (DPOAE). Methods : The subjects included 871 neonates who were admitted to the neonatal intensive care unit of the Pediatric Department in Soonchunhyang University Bucheon Hospital from May, 2001 to December, 2004. They were screened using DPOAE. Based on DPOAE, we divided the neonates in two groups : 'Pass' and 'Refer'. The differences in risk factors between the pass group and the refer group were analyzed. Results : The incidence of the refer group was 12.1 percent(106 out of 871). The bilateral refer rate was 5.4 percent(47 out of 871). And the unilateral refer rate was 6.7 percent(59 out of 871). Gender, birth place, family history of hearing loss, small/large for gestational age, obstetrical factor, hyperbilirubinemia and use of gentamicin were not statistically related to the refer rate. Statistically related to refer rate were birth weight, resuscitated neonates, Apgar score, craniofacial anomaly, mechanical ventilator application, sepsis, using of vancomycin(P<0.05). The prevalence of hearing impairment (${\geq}60dB$) in this study was 2 percent(18 out of 871). Conclusion : This study showed a higher prevalence of hearing impairment in high-risk neonates. Thus neonatal hearing screening should be carried out in high-risk neonates.

Background: Recent improvements in interventional procedure and medical therapy for congestive heart failure result in an increase of number of patients with ischemic cardiomyopathy considered for coronary artery bypass grafting. We retrospectively review the results of CABG in these patients with decreased LV function to know the early and mid-term follow-up results. Material and Method: Between January 2001 and June 2005, 1,143 patients underwent coronary artery bypass grafting and 144 of these patients had preoperative left ventricular function of equal to or less than 35% ${(LVEF{\leq}\;35%)}$. There were off-pump coronary artery bypass grafting (OPCAB) in 66 cases (45.8%), on-pump beating heart coronary artery bypass grafting in 34 cases (23.6%) and conventional coronary artery bypass grafting in 44 cases (30.6%). The combined operations including mitral annuloplasty were 48 cases in thirty five patients (24.3%). Result: The mean number of dstal anastomosis were $3.5{\pm}1.3$. The median postoperative duration of stay in intensive care unit and hospital was 2 days and 8 days, respectively. There were 6 early death (4.2%) and causes of deaths were ventricular tachycardia in 5 patients, small bowel infarction in one patient. Mean follow-up time was $21{\pm}14$ months $(4{\sim}54\;months)$. The 1-year was $95{\pm}2%$ and 3-year survival rate was $83{\pm}7%$, the 1-year and 3-year cardiac event-free survival were ${88{\pm}3%\;and\;69{\pm}7%}$, respectively. Conclusion: Based on satisfactory early and mid-term results in our study, CABG should be carried out as actively as possible in patients with ischemic cardiomyopathy. Postoperative aggressive management for ventricular arrhythmia would be helpful for better results.

Purpose : This study investigated the clinical course and prognostic factor of very low birth weight infants (VLBWI) with hemodynamically significant congenital heart defects (CHDs). Methods : Medical records of 1,098 VLBWI with birth weight <1,500 g who had been admitted to the neonatal intensive care unit of Samsung Medical Center from October 1994 to December 2007 were reviewed retrospectively. The data for these patients with hemodynamically significant CHD (n=33) were compared with those without CHD (n=1,065). Results : The incidence of CHD was 3.0% (33 patients) 7 patients (21%) had CHD combined with the congenital abnormalities or chromosomal disorders. The most common CHD was a ventricular septal defect. The incidence of intrauterine growth retardation was higher in patients with CHD than in patients without CHD (34% vs. 20%), but there were no significant differences in gestational age, birth weight, respiratory distress syndrome, bronchopulmonary dysplasia, necrotizing enterocolitis, severe intraventricular hemorrhage (${\geq}$Gr III), and periventricular leukomalacia. Cardiac surgery was performed on 13 patients (39%). Nine patients received staged operations, and 10 patients received early intervention. The overall mortality in patients who had CHD was higher than in the patients who did not have CHD (27% vs. 16%). In patients with CHD, congenital abnormalities or chromosomal disorders were more important factors for increased mortality (86% vs. 11%) than the degree of complexity of CHD (19% vs. 42%). Conclusion : The most important prognostic factors of VLBWI with CHD are the associated congenital abnormalities or chromosomal disorders.

This study examined the factor structure of the Child Behavior Checklist Dysregulation Profile(CBCL-DP) for school-aged children in Korea identified differences in the level of maladjustment and problematic behaviors between the clinical group which had characteristics of CBCL-DP and the control group which did not. Confirmative factor analysis was performed on three alternative models from the literature to determine which was the most appropriate factor structure for the CBCL-DP. The result showed that the bi-factor model fit the sample data better than both the one and second-factor models. To confirm that the bi-factor model was the most appropriate factor structure, regression paths with relevant variables examined. The showed that CBCL-DP with the bi-factor model was associated with executive function difficulty as reported by parents and with school adjustment and all sub-factors of strength and difficulty as reported by teachers. The results also showed that this model had a different relationship with anxiety/depression, aggressive behavior, and attention problems than the other models. The clinical group was shown to have more executive function difficulty, worse adjustment of school life and to be less likely to engage in desired behaviors than the control group. These results indicate the CBCL-DP is more related to negative outcomes than any other factor, and that the bi-factor model was found to best fit the sample data, consistent with other studies. The early discovery of CBCL-DP can be used to provide interventions for high-risk children who exhibit emotional and behavioral problems, making its detection a significant diagnostic tool. The implications of these result, the limitations of this study, and areas for future research are discussed in this paper.
