Objectives : This research is to figure out the neurofeedback treatment for the inattentive children is effective in improving attention deficit and furthermore, in relieving hyperactivity and impulsivity. Methods : 20 children subjects participated for this study. C3-A1 protocol neurofeedback was given 15 to 20 times to each child, it is carried out to compare the degree of attention in each case every 5 times of neurofeedback by using ADHD Rating Scale-IV : Parent Version(ARS) and Attention Deficit Disorder Evaluation Scale-Home Version(ADDES-HV). Results : The subscale of mean inattention score of ARS was reduced from 14.2 to 8.8 significantly(p<0.05) after 20 sessions of neurofeedback treatment, also the subscale of mean impulsivity/hyperactivity score of ARS from 13.3 to 7.1. The subscales of mean inattention, impulsivity and hyperactivity score of ADDES-HV was also reduced significantly(p<0.05) after 20 sessions of neurofeedback treatment. The changes of scores appeared significantly(p<0.05) from 10-15 sessions of neurofeedback treatment. Conclusion : The results of this study suggest that neurofeedback can improve children's attention deficit, hyperactivity and impulsivity, there exists the possibility of being a method to treat ADHD.

The paper examines the role of some determinants of economics, politics and institutions on the budget deficit volatility in some countries of the Association of South East Asian Nations (ASEAN) such as Indonesia, Thailand and Vietnam. The paper uses the fixed effects model (FEM) and the random effects model (REM) to investigate panel data of these countries in the period of 1990-2018. Moreover, the study also explores ordinary least square (OLS) to analyze time-series data for each country in the same period to make comparison among them. The economic data is collected from international financial statistics and world development indicators. The data on political variables are collected from International Country Risk Data Guide (ICRG). The empirical results both confirm that corruption and political stability are important indicators of budget deficit. Besides, the paper suggests authorities should pay more attention on improving the institutional setup of the economy in order to avoid high and unstable deficit. The findings offer new insight on the budget deficit in essence and suggest that the most important thing need to be done ahead is to strongly implement anti-corruption actions. By doing so, the status of budget deficit would be remarkably improved immediately.

The purpose of this study was to examine the reliability and validity of a Korean form of Childhood Attention Problem(CAP) scale. CAP were administered to 98 normal elementary school students as control group and 98 attention deficit hyperactivity disorder patients. Male students showed high scores than female students in both subscale and total scores, but not statistically significant. There were no significant difference in CAP scale between male students and female students in attention deficit hyperactivity disorder patients. In the reliability test, the test-retest reliability coefficient was highly satisfactory and that of inattention subscale was 0.83, impulsivity subscale was 0.70 and total score was 0.82. In the reliability test by internal consistency, the Cronbach $\alpha$ coefficient was highly satisfactory and that of inattention subscale was 0.91, overactivity subscale was 0.89(p<0.05). The concurrent validity between CAP scale and ADDES-BV scale was 0.85 in attention deficit hyperactivity disorder patient group and 0.73 in normal control group(p<0.05). In discriminant validity test between attention deficit hyperactivity disorder patient group and normal control group, the patient group showed higher score(p<0.05). The total discriminant capacity of the patient group in CAP was 93.4%. In this point of view, CAP scale showed high reliability and validity in applying to Korean subjects and was proved to be the good and simple screening test tool for attention deficit hyperactivity disorder research and can help many young patient to treat early.

The purpose of this study was to examine the reliability and validity of attention deficit disorder evaluation scale-school version(ADDES-SV). Between October 1996 and November 1996, ADDES-SV was administered to 263 elementary school students in the second grade and between Jun 1996 and October 1996, 28 attention deficit hyperactivity disorder patients. In the reliability test, the test-retest reliability coefficient was significantly high and that of inattention was 0.88, that of impulsivity was 0.80, that of hyperactivity was 0.83 and total score was 0.83. In the reliability test by internal consistancy, the Cronbach $\alpha$ coefficient was significantly high and that of inattention was 0.98, that of impulsivity was 0.87, that of hyperactivity was 0.87(p<0.05). The half-sprit reliability coefficient by first-second half method showed high correlation and that of inattention was part 1: 0.96, part 2: 0.96 impulsivity was part 1: 0.95, part 2: 0.93, hyperactivity was part 1: 0.92, part 2: 0.94(p<0.05). Inter-rater reliability by pearson correlation coefficient was significantly high and that of inattention was 0.92, that of impulsivity was 0.87, that of hyperactivity was 0.89 and total score was 0.89. The concurrent validity between ADDES-SV and CAP scale was 0.85 in attention deficit hyperactivity disorder patient group and 0.79 in normal control group(p<0.05). In discriminant validity test between attention deficit hyperactivity disorder patient group and normal control group, the patient group showed higher score(p<0.05). The total discriminant capacity of the patient group in ADDES-SV was 94.6%. In this point of view, ADDES-SV scale showed high reliability and validity in applying to Korean subjects and was proved to be the useful screening test tool for attention deficit hyperactivity disorder research.

Objectives: Children with attention-deficit hyperactivity disorder(ADHD) often have difficulties in social behavior. The aim of this study was to evaluate the effectiveness of a short-term training program for improving social skills, self-perception and attention deficits. Methods: The subjects were nine children diagnosed with ADHD with(or without) other mental disorders using the Diagnostic Interview Schedule for Children(DISC-ADHD) module. Children were given eight sessions of a social skills training program. Parents of children simultaneously participated in their own training which was designed to support their children's generalization of skills. Assessments included child, parent and teacher ratings of social skills, self-perception and attention deficit at baseline and post-treatment. Results: Social skills training led to significant improvements in child-reported measures of self-esteem, in teacher reported measures of social skills, and in parent-reported measures of attention deficit. Conclusion: This study suggests that short-term social skills training programs for children with ADHD may improve their social skills, self-perception and attention deficits.

Cognitive dysfunction is a common symptom of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and Huntington's disease, and is known to be caused by the structural and functional loss of neurons. Many natural agents that can improve cognitive function have been developed and assessed for efficacy using various cognitive deficit animal models. As the gut environment is known to be closely connected to brain function, probiotics are attracting attention as an effective treatment target that can prevent and mitigate cognitive deficits as a result of neurodegenerative diseases. Thus, the objective of this review is to provide useful information about the types and characteristics of cognitive deficit animal models, which can be used to evaluate the anti-cognitive effects of probiotics. In addition, this work reviewed recent studies describing the effects and treatment conditions of probiotics on cognitive deficit animal models. Collectively, this review shows the potential of probiotics as edible natural agents that can mitigate cognitive impairment. It also provides useful information for the design of probiotic treatments for cognitive deficit patients in future clinical studies.

Purpose: This study was a meta-analysis designed to identify effects of Cognitive Behavioral Therapy (CBT) interventions in alleviating main symptoms of Attention Deficit Hyperactivity Disorder (ADHD) among school-aged children in Korea. Methods: Examination of several databases including Research Information Sharing Service, Korean Studies Information Service System, Data Base Periodical Information Academic and hand-searched article references, resulted in identification of 1,298 studies done between 2000 and 2013 of which 21 met the inclusion criteria. Comprehensive Meta-Analysis version 2.0 was used to analyze effect sizes, explore possible causes of heterogeneity, and check publication bias with a funnel plot and its trim-and-fill analysis. Results: Overall effect size of CBT intervention was large (g=1.08) along with each outcome of self-control (g=1.26), lack of attention (g=1.02), social skills (g=0.92), and hyperactivity (g=0.92). For heterogeneity, moderator analysis was performed, but no significant differences were found between the RCT (Randomized Controlled Trials) group and the NRCT (Non RCT) group. Also, meta-regression was performed using sample size, number of sessions, and length of session as predictors, but no statistically significant moderators were found. Finally, a funnel plot along with trim-and-fill analysis was produced to check for publication bias, but no significant bias was detected. Conclusion: Based on these findings, there is clear evidence that CBT intervention has significant positive effects on the main symptoms of school-aged children suffering ADHD. Further research is needed to target diverse age groups with ADHD along with more RCT studies to improve the effectiveness of the CBT intervention.

Objectives: Although aggressive behavior in children and adolescents with attention-deficit/hyperactivity disorder (ADHD) has previously shown correlations with hyperactivity/impulsivity, few studies have examined its association with inattention or the effect of working memory on aggressive behavior. This study aimed to assess the relationship between inattention and aggressive behavior and the effect of working memory on the relationship between inattention and aggressive behavior in children and adolescents with ADHD. Methods: Thirty-one children and 26 adolescents with ADHD were retrospectively investigated. The subjects completed the Korean Wechsler Intelligence Scale for Children-Fourth Edition (K-WISC-IV), the Korean Child Behavior Checklist (K-CBCL), and the Korean Children's Depression Inventory (CDI). Results: Inattention was positively correlated with aggressive behavior in children and adolescents with ADHD and working memory showed an insignificant correlation. However, working memory had a significant moderating effect on aggressive behavior by interacting with inattention. The moderating effect of working memory manifested when the working memory index score on the K-WISC-IV was 73.5 points or higher, and it had a significant effect on aggressive behavior. Conclusion: This study shows that the severity of inattention and hyperactivity/impulsivity should be addressed to provide appropriate treatment to children and adolescents with ADHD who exhibit aggressive behavior.

Objectives: The study compared the intelligence test profiles of Tourette's Disorder (TD), attention-deficit hyperactivity disorder (ADHD), and TD with ADHD (TD+ADHD) groups. Methods: The Korean Wechsler Intelligence Scale for Children-third edition (K-WISC-III) and Korean Wechsler Intelligence Scale for Children-fourth edition (K-WISC-IV) were administered to 13 children and adolescents with TD, 17 children and adolescents with ADHD, and 15 children and adolescents with TD+ADHD. Each parameter was compared among the groups using the Kruskal-Wallis test. Results: The mean scores of the freedom from distractibility/working memory index (FD/WMI) and the digit span and arithmetic subtests of the TD+ADHD group were significantly lower than those of the TD group. Conclusion: According to the intelligence test results, the comorbid ADHD+TD group showed a significant decrease in working memory compared to the TD group. These findings are similar to those of previous research on cognitive functions and suggest that the TD+ADHD comorbid and TD alone groups exhibit different endophenotypes. The results also imply that WISC-III and WISC-IV, the most commonly used intelligence tests clinically, are effective in evaluating cognitive functions such as attention. Further research is required to confirm these results.

The purpose of this study was to investigate the correlation between food behavior and Attention Deficit Hyperactivity Disorder (ADHD) score in elementary students in Suwon-si, Gyeonggi-do. Two hundreds and thirty two students (113 male and 119 female) in grades 4~6 participated. We assessed food behavior by using Nutrition Quotient (NQ). NQ was examined by an NQ questionnaire, which consisted of 19 food behavior checklist items. Their items were grouped into five categories: balance, diversity, moderation, regularity, and practice. All data were statistically analyzed by SPSS 18.0. Among the five factors, NQ for food behavior and balance factor showed the lowest score, whereas that of diversity factor showed the highest score. The final Nutrition Quotient (NQ) score weighted on such five factors was 62.59 points. The average level of ADHD by Conners-Wells Adolescent Self-Report Scale (Short Form) [CASS(S)] was 17.02 points out of a total of 81 points. Six students (2.2%) who scored more than 41 points were classified as ADHD risk. By gender, male students (19.76 points) showed a higher CASS(S) score than female students (14.41 points) did. There was a significant negative correlation between NQ and CASS(S) score (r=-0.445, P<0.001). Multiple regression determined the effects of moderation ($Exp({\beta})=-0.193$, P<0.01) and practice ($Exp({\beta})=-0.345$, P<0.001) on CASS(S) score. In conclusion, distinctive nutritional education is needed for students with a high level of ADHD to help their understanding considering their different levels of attention.
