Objectives: The purpose of this study is to study the personality traits and cognitive characteristics of the Sasang constitution by comparing the Personality Test and Neuropsychological Test. Methods: A total of 121 subjects were analyzed with the results of a Two Step Questionnaire for the Sasang Constitution Diagnosis (TS-QSCD). Among them, the Personality Tests (SPQ, EPQ, TCI) and the Neuropsychological Tests (A-VLT, CPM, Stroop-CWIT, WCST) were processed and analyzed for Soyangin, Taeeumin, Soeumin. Results: 1. In the results of the SPQ, the Soyangin showed a significantly higher score than did the Taeeumin and Soeumin in Behavior, Emotionality, Cognition, as well as the Total Score. The SPQ-C score and SPQ-T were significantly higher for Soyangin, Soeumin and Taeeumin, in that order. 2. In the results of the EPQ, the Soyangin showed a significantly higher score than did the Taeeumin and Soeumin in Extraversion - introversion. Soeumin showed a significantly higher score than did the Soyangin and Taeeumin in Neuroticism. Soyangin also showed a significantly higher score than Taeeumin in Venturesomeness. 3. For the results of the TCI, the Soyangin showed a significantly lower score than did Taeeumin and Soeumin in Harm-Avoidance, but a significantly higher score in Persistence and Self-Directedness. Soyangin and Taeeumin showed a significantly higher score than did Soeumin for the total score of Self-Directedness+Cooperativeness. 4. The results of the Computerized Neuropsychological Tests (A-VLT, CPM, Stroop-CWIT, WCST) showed no significant differences between the Sasang constitution. Conclusions: The EPQ, TCI score showed significant differences between the Sasang constitution. But the Computerized Neuropsychological Tests developed to evaluate cognitive abilities did not show differences between the constitutional individuals and showed limitations as a research tool. Further studies are needed to devise a research method for ascertaining the cognitive behavioral characteristics of the Sasang constitution.

This study was done objected to the chronic stroke patients in order to evaluate change in brain wave activity and cognitive performance when Neurofeedback training. The subjects were over 6 months ago in chronic stroke patients screened-test through the 20 patients, 10 persons in each group were randomly placed. This was carried out in 4 weeks in total, with control group(n=10) on general physical therapy and experimental group(n=10) on general physical therapy along with Neurofeedback training. The general physical therapy was applied 5 times a week, 30 minutes at once, Neurofeedback training was applied as equally as the general physical therapy, which makes 20 times in total. To learn about the effect before the training, after training, and 2 weeks after the training in electric physiological measurement method of the brain, electroencephalogram(EEG) to examine challenges by calculating the absolute spectrum power for standard EEG change(%), followed by evaluation with clinical assessment tool MMSE-K, Stroop Test, Digit Span Test. As a result of comparing the change in brain wave through EEG, after training and 2 weeks after training showed that absolute ${\alpha}$-power and absolute ${\beta}$-SMR power of experimental group have increased and absolute ${\theta}$-power decreased significantly compared to experimental group I. Moreover, the MMSE-K score in trial appraisal has increased significantly, and the error in Stroop Test and Digit Span Test has decreased significantly. such results, with the chronic stroke patient's brain wave control, Neurofeedback training was determined to improve the cognitive performance. this study suggests a new training possibility of stroke patients by identifying the training effects of Neurofeedback training that trains the brain directly with brain wave control.

Objectives : The purpose of this study was to investigate the deficits in executive function in children with ADHD and anxiety disorder, and further, to characterize executive function deficits among the two groups. Methods : Subjects consisted of 60 children between the ages of 5 and 14 (16 Normal, 24 ADHD, 20 Anxiety Disorder). Neuropsychological tests (KEDI-WISC, CCTT, STROOP, WCST, ROCF) for assessing cognitive and executive function were individually administered to all subjects. Results : There were no significant differences in FSIQ or PIQ among the three groups. However, the ADHD group tended to score lower on the VIQ and subtest of similarity, vocabulary, and digit span tests. The three groups did not significantly differ with respect to CCTT test results. On the STROOP test, the ADHD group showed poor performance on the word, color, and color-word subtests. The three groups did not exhibit significant differences in WCST test results ; however, the anxiety group performed poorly belonging to below 25 percentile rank on perseverative response. On the ROCF test, the ADHD group performed poorly with respect to their organization score and in particular, regarding copy and immediate recall. The anxiety group also performed poorly with regard to organization ; however, this was limited only to immediate recall. Conclusion : Children with ADHD displayed poor inhibition and organizational abilities compared to children with anxiety and normal controls. Further, children with anxiety disorder exhibited low cognitive flexibility and voluntary problem-solving abilities compared to ADHD children and normal controls. Based on these results, we suggest that the characteristics of executive dysfunction in ADHD and anxiety disorder in children are different.

Objectives Obsessive-compulsive disorder (OCD) and schizophrenia have many common clinical and neurocognitive features. However, not all of them share the same underlying mechanism. The aim of this study was to discover evidences that indicate a pathophysiological mechanism specific to OCD by comparing correlations of quantitative electroencephalography (QEEG) patterns and neurocognitive function in patients with OCD and schizophrenia. Methods Resting-state QEEG data of total 265 patients were acquired retrospectively and parameters such as absolute power, relative power and peak frequency were analyzed from the data. Stroop test and Trail Making Test results as well as demographic features were reviewed for this study. The correlation of neurocognitive functions and brain electrical activities in each group were assessed and compared by correlation analysis. Results Compared with the OCD group, the schizophrenia group performed poorly in neurocognitive tests. Mean values of QEEG parameters in patients with OCD and schizophrenia did not show significant differences. Both absolute and relative power of alpha rhythm in central and frontal regions showed significant positive correlation with Stroop test results in OCD patients. Conclusions Findings in this study shows distinctive correlations between frontal executive dysfunction and frontal alpha rhythm in the OCD patients, both of which might be a candidate for endophenotype underlying obsessive rumination.

Purpose: We investigated the effects of transcranial stimulation and task-oriented training on upper extremity and cognitive function in chronic stroke patients. Methods: A total of 30 patients were randomly divided into transcranial stimulation and task-oriented training groups (TT) and task-oriented training groups (TO). The TT group performed 30 min 5 times a week for 4 weeks in task-oriented training combined with transcranial direct current stimulation. The TO group performed 30 min 5 times a week for 4 weeks in task-oriented training. To measure upper extremity function, the Jebsen-Taylor Hand Function Test, Manual Function Test, and Cognitive Function Test were performed using the Stroop Test and the Trail Making Test. Results: There was a significant difference (P < 0.05) before and after training in both groups, and the TT group showed significant improvement in both groups. Conclusion: In this study, we confirmed transcranial stimulation and task-oriented training in upper extremity function and cognitive function in patients with chronic strokes.

Objective : This study is planned to determine the neurocognitive difficulties of hydrocephalic adults. Methods : The research group contained healthy adults (control group, n : 15), and hydrocephalic adults (n : 15). Hydrocephalic group consisted of patients with idiopathic aquaduct stenosis and post-meningitis hydrocephalus. All patients were followed with shunted hydrocephalus and not gone to shunt revision during last two years. They were chosen from either asymptomatic or had only minor symptoms without motor and sensorineural deficit. A neuropsychological test battery (Raven Standart Progressive Matrices, Bender-Gestalt Test, Cancellation Test, Clock Drawing Test, Facial Recognition Test, Line Orientation Test, Serial Digit Learning Test, Stroop Color Word Interference Test-TBAG Form, Verbal Fluency Test, Verbal Fluency Test, Visual-Aural Digit Span Test-B) was applied to all groups. Results : Neuropsychological assessment of hydrocephalic patients demonstrated that they had poor performance on visual, semantic and working memory, visuoconstructive and frontal functions, reading, attention, motor coordination and executive function of parietal lobe which related with complex and perseverative behaviour. Eventually, these patients had significant impairment on the neurocognitive functions of their frontal, parietal and temporal lobes. On the other hand, the statistical analyses performed on demographic data showed that the aetiology of the hydrocephalus, age, sex and localization of the shunt (frontal or posterior parietal) did not affect the test results. Conclusion : This prospective study showed that adult patients with hydrocephalus have serious neuropsychological problems which might be directly caused by the hydrocephalus; and these problems may cause serious adaptive difficulties in their social, cultural, behavioral and academic life.

The subjects were individually presented with the Maxi-doll task to examine false belief and with the flower-star (Stroop-like day-night) test to examine inhibitory control skill. In the $1^{st}$ session, the subjects were tested with both the Maxi tesk and the flower-star test. Three days later, subjects were retested with the Maxi task, including an inhibitory cue. Data were analyzed by 3-way ANOVA, age(2) $\times$ inhibitory level(2) $\times$ task type(Maxi-task or Maxi-including cue). All the main effects were significant and the interaction effect between inhibitory level and task type was also significant. Thus, their understanding of the mind and inhibitory control skill both influence children's performance on a typical false belief task.

Background and Purpose: Dual walking task such as crossing over an obstacle may serve as an excellent tool for predicting early cognitive decline. Thus, this study aimed to investigate correlation between walking while crossing over an obstacle and executive functions under different gait phases to validate the use of walking with an obstacle for predicting early cognitive decline. Methods: A cross-sectional study was conducted on 48 elderly individuals from 2 day-care centers and 3 welfare-centers in Seoul and Gyeonggi, Korea. Executive function tests (Trail Making Test, Stroop test) and dual walking tests (gait speed, cadence, stance time, gait cycle time) were performed and compared using partial correlation analysis. Results: There were significant correlations between executive function and most of the gait variables (stance time, cadence, and gait cycle time) (p<0.05) when crossing over an obstacle while walking. Especially, stance time exhibited significant correlations with most executive functions (p<0.05). Conclusions: When evaluating executive function during walking with an obstacle, post-obstacle-crossing phase and stance time need to be observed.

Objectives : This study was conducted in order to examine the reliability and validity of the Children's Color Trails Test (CCTT). The objective of the study was also to provide the Korean normative data for the CCTT. Methods : Normative samples consisted of 766 children and adolescents living in Seoul and aged from 5 to 15 years. Eighty children who were diagnosed with ADHD, based on the DSM-IV criterion, were recruited from Seoul National University Children's Hospital. Among them, 46 ADHD children were receiving medication, while 34 children were drug-free. Results : The scores of the CCTT were significantly correlated with those of the Stroop test. Three factors were extracted through factor analysis-visual tracking and cognitive flexibility, distractibility and susceptibility to interference, and simple attention and impulsivity. The completion time of the CCTT for all children tended to decrease as age increased. There were significant differences in the CCTT scores between the ADHD group receiving medication, the ADHD-drug free group and the normal groups. The CCTT also showed sound test-retest reliability. These results confirmed the reliability and validity of the CCTT. Finally, we provided the Korean normative data for the CCTT. Conclusion : These results suggest that the CCTT is a reliable and valid test, which can be used to assess frontal function related to child psychiatric disorders in Korean children.
