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.

Objective : The amygdala has been considered to be a critical region in the pathophysiology of social anxiety disorder, but subregional connectivity pattern has not been examined yet despite lots of previous functional neuroimaging studies. Methods : Resting-state functional magnetic resonance imaging data was obtained in 19 patients with social anxiety disorder and 20 normal controls, and default mode functional connectivity with each of basolateral, centromedial and superficial areas of the amygdala was measured and compared between the two groups. Results : Differential amygdala-based networks between the two groups were distributed to all over the brain. In particular, however, a bias on the amygdala-cingulate pathway was observed in the superficial amygdala only. Connectivity strengths between the superficial amygdala and perigenual anterior cingulate cortex were correlated with scores of social interaction and avoidance. Conclusion : Our findings provide new insights into understanding of the intrinsic cognitive bias model of social anxiety disorder. An abnormality in superficial amygdala-anterior cingulate connectivity may influence on cognitive processing of socially-relevant information in social anxiety disorder.

Objectives: This article aims to review clinical studies related to traditional Korean medicine (TKM) for cancer-related cognitive impairment (CRCI) up to date. Methods: EMBASE, Pubmed and eight Korean databases were searched for clinical studies about TKM for CRCI up to July 2016. We selected articles about subjects with cancer, using TKM interventions including acupuncture, moxibustion or herbal medicine, containing assessment about cognitive function. Results: Two randomized controlled trials (RCTs) and one randomized controlled feasibility study were included. Selected studies were containing assessments about cognitive function but not as primary outcomes. The three studies included one acupuncture study and two herbal-medicine studies. Only one herbal-medicine study showed improvement in cognitive function. Conclusions: Few clinical studies mainly focusing CRCI treated with TKM have been performed and have shown contradictory results until now. Future studies should be performed considering findings from pre-clinical and clinical studies altogether, and they should be controlled to minimize risk of bias thorough out overall courses of designing, conducting and reporting them.

Purpose: This study investigated evidence for the effects of community-based cognitive rehabilitation programs for demented elderly. Methods: The literature review covered studies between 2004 and 2014, and searched international databases including Ovid-MEDLINE, EMBASE, and the Cochrane Library. The Risk of Bias Assessment Tool for Non-Randomized Studies was used by two reviewers to evaluate independently the quality of the selected articles. Results: Eighteen studies were selected through a systematic search of the literature. About three quarters of the studies showed that the community-based cognitive rehabilitation programs provided by nurses were significantly effective in enhancing cognition among elderly individuals with dementia. Conclusion: Based on these results, we suggest that nurse is an appropriate profession to manage cognitive rehabilitation or cognitive enhancement programs for demented elderly individuals. Therefore, the current system in which caregivers provide cognitive rehabilitation programs for demented elderly individuals must be reformed.

Purpose: The present study aimed to review the characteristics of cognitive behavioral therapy (CBT) programs for alcohol use disorders and to examine the outcomes of such programs. Methods: We searched for domestic and foreign studies that implemented a CBT program for alcohol use disorders, published from 2006 to 2017. Studies that met inclusion/exclusion criteria were selected and a quality assessment was performed using the Risk of Bias (RoB) and Risk of Bias Assessment Tool for Nonrandomized Studies (RoBANS) instruments. We utilized a five-stage analysis process, through which nine experimental studies were selected. Results: Of these nine studies, four were randomized controlled trials, four used a quasi-experimental design, and one used a qualitative design. The CBT involved the three domains of cognitive reconstruction, problem solving, and coping. Coping with drinking situations and communication constituted most of the sessions. The outcomes of such interventions showed that CBT had a positive effect on alcohol use and self-evaluation. Conclusion: CBT is an effective way to change alcohol use behaviors, motivation, interpersonal relationships, emotional control, and self-efficacy among patients with alcohol use disorders. This study provides evidence for the effectiveness of CBT-based programs for the treatment of alcohol use disorders.

This study is to apply behavioral economics-an economics that studies actual human behavior based on cognitive psychology-to the farming decision-making process of onion and garlic farmers. Of behavioral economic theories, dual system theory and prospect theory (value function), heuristic and bias were surveyed and examined in the field. The reference point of farmers was farming experience of the previous year, and so they showed reference dependence and anchoring heuristic, not rational thinking on production cost plan. And they showed status quo bias that cultivated continuously the previous year or the present crop. This status quo bias is related to loss aversion propensity. Farmers did not usually change cultivating crops, in other words, they showed diminishing sensitivity-insensitive to those that the more revenue or loss was increased. This diminishing sensitivity is related to loss aversion propensity and status quo bias. Also, farmers had representativeness heuristic because they regarded auction price of Garakdong wholesale market as the standard price level despite various prices by production region. And farmers had the affect heuristic that they depended on producers' organization data more than the state-run research institute ones about cultivation intentions and actual situations.

Purpose : This study aimed to present evidence by analyzing the characteristics and effectiveness of group art therapy interventions through an examination of domestic studies on group art therapy for older people with dementia. Methods : The database used DBpia, Riss, and Google Scholar, and the research period was from 2016 to November 2021. For the selected studies, the level of evidence was analyzed, bias evaluation was performed, and patient, intervention, comparison, and outcome were analyzed. For the evaluation of bias, the risk of bias assessment tool for non-randomized study (RoBANS) and Cochrane's risk of bias (RoB) were used. Results : As for the level of evidence of the included studies, level I consisted of five studies, and levels II and III each had one article. As a result of the bias evaluation of five studies through RoB, a "low risk of bias" was found for incomplete result data, selective result reporting, and others, except for four unclear evaluation areas. The "low risk of bias" ratio was 0~25 % in the evaluation of bias in two studies through RoBANS. For the evaluation tool, cognitive evaluation tool was used the most while mini-mental state examination-Korea was used the most frequently. For the intervention method, the most frequently used was group art therapy that employed recall in three studies, while collage, Korean painting, use of paper media, and procedural memory were used in each of the other studies. Each intervention was found to be significantly effective overall. Conclusion : This study provided clinical evidence by systematically reporting research on group art therapy for older people with dementia. In the future, it is necessary to check the effect of group art therapy on various areas other than cognition for older people with dementia. Moreover, the study should be conducted with the risk of bias sufficiently taken into consideration.

This paper derives a consistent and bias corrected extension of Akaike's Information Criterion (AIC), $AIC_{bc}$, based on Kullback-Leibler information. This criterion has terms that penalize the overparametrization more strongly for small and large samples than that of AIC. The overfitting problem of the asymptotically efficient model selection criteria for small and large samples will be overcome. The $AIC_{bc}$ also provides a consistent model order selection. Thus, it is widely applicable to data with small and/or large sample sizes, and to cases where the number of free parameters is a relatively large fraction of the sample size. Relationships with other model selection criteria such as $AIC_c$ of Hurvich, CAICF of Bozdogan and etc. are discussed. Empirical performances of the $AIC_{bc}$ are studied and discussed in better model order choices of a linear regression model using a Monte Carlo experiment.
