The purpose of this study was to evaluate the effects of recreational exercise on cognition, depression, dynamic balance and leg strength in elderly women. This study was nonequivalent control group pre-post test design. Subjects were divided into two group(exercise group=14, control group=13). Experimental group conducted recreational exercise program for eight-week. Cognition was assessed by K-WAIS(object assembly & digit symbol) and depression were assessed by questionnaire. Dynamic balance(DB) and leg strength(LS) were assessed by 244cm up & go and sit to stand respectively. The collected data analyzed by Wilcoxon singed rank test and Mann-Whitney U test. The exercise group significantly improved cognition(object assembly) and DB, but control group significantly reduced DB. DB in exercise group were significantly greater than in control group after eight-week. The program was effective on cognition and dynamic balance in elderly women.

In this paper, in order to compose the visual perception cognitive function training content that can be linked with the IPUZZLE image block, an interactive content device that utilizes photos and videos of smartphones. Four areas of visual memory, visual continuity, spatial relationship, and visual discrimination were derived and the content operation, application method, and scenario were written. It was intended to continuously give and induce children's desire to participate in training by designing the content image and developing the existing learning terrain visual and perceptual cognitive function training materials in the form of mobile mini-games. Experiential activities were conducted for general children and their guardians using the developed contents, and the results were found to be significant in terms of concentration, effect, and effect compared to basic puzzle toys. It is expected that this thesis will be a meaningful data for the study of cognitive function improvement activities based on digital toys and contents.

Objectives: The purpose of this study was to evaluate the difference of cognitve function among patients with posttraumatic stress disorder according to severity of symptoms. Methods: The subjects were 90 psychiatric inpatients and outpatients with posttraumatic stress disorer(by DSM-IV criteria) after traffic accident. The severity of symptoms was assessed by MMPI subscales; depression, psychasthenia, schizophrenia. The impairment of cognitive function was assessed by Korean Wechsler Intelligence Scale(K-WAIS). Based on scores of the MMPI subscales, the patients were divided into high group(above 70 percentile) and low group(below 30 percentile). We estimated the difference of the K-WAIS score and subtest score in the low group and high group of the MMPI subscales by indedpendent t-test. Results: The scores of high group is significantly higher in the subtests of information, vocabulary, similarity, picture completion, and picture arrangement than the low group for psychasthenia subscale of MMPI. And the score of high group is significantly higher in full scale I.Q., verbal I.Q., performance I.Q., verbal subscales except digit span and simiarity, and performance subscales than low group for schiozphrenia subscale of MMPI. Conclusion: It was found cognitive function was more impaired in the group of PTSD with severe symptom compared to the group of PTSD with mild symptoms. We suggest that psychiatrist should consider various cognitive approaches as well as pharmacotherapy in the management of PTSD.

Objective : The purpose of this study was to develop a Yonsei dual task cognitive screening test (Y-DuCog) for the elderly. Methods : The reliability and validity test of Y-DuCog (Yonsei Dual Task Cognitive Screening Test) was developed by 229 elderly people aged over 60 years from community organizations at Gyeonggi-do and Chungcheong-do from May 2019 to August 2019. In addition, the criteria for classifying elderly with cognitive impairment were presented. Results : The correlation analysis between MMSE-K, MoCA-K and Y-DuCog were a correlation between the DTE and CRR of Y-DuCog. As a result of internal consistency, Cronbach's-α values of DTE and CRR showed .848 (p<.01) and .916 (p<.01), respectively. The test-retest reliability was high. The screening point showed 88.7% sensitivity and 83.5% specificity at 31.76 seconds in total DTE, and 84.5% sensitivity and 76.6% specificity at 0.38 in total dual-task CRR. Conclusion : This study verified the reliability and validity of Y-DuCog. It was found that the level of education was not a barrier to the undertaking of this test. Furthermore, the test could be performed easily and quickly. It is also expected to be used to evaluate the effectiveness of cognitive function assessment and intervention methods in the elderly.

This study was undertaken to investigate the effect of cognitive rehabilitation program (CRP) using virtual content, for recovering patients with cerebrovascular disease (CVD). A total of 34 patients with CVD were divided into a control group and an experimental group, and subsequently subjected to a virtual content based CRP, followed by cognition, ADLs, and upper limbs. The control group completed a universal rehabilitation program (URP), and the experimental group was provided a URP and a virtual content based cognitive rehabilitation program. For both groups, respective programs were conducted twice a day, 5 times a week for 4 weeks. Both groups showed significant improvement in ADLs (p<0.05); but the amount of change in the experimental group 5 point improved significantly (p<0.05). Cognition was significantly different for both groups (p<0.05). However, the experimental group showed a greater change (2 point) than the control group when considering the amount of change (p<0.05). Comparing the amount of change in the upper extremity, the experimental group showed a significant change (0.7 point) than the control group (p<0.05). This study confirms that compared to URP, CRP using virtual content significantly improves ADLs and cognition.

Objectives: The authors intended to evaluate long-term outcome of group cognitive behavioral therapy(GCBT) for panic disorder and examined the variables to predict high end-state functioning in 12 months follow-up. Methods: 236 patients meeting DSM-IV criteria for panic disorder were assessed by STAI, ASI, BDI, BSQ, PBQ, ACQ at pre & post treatment, and were asked about the frequency of panic attacks during recent one month. We executed stepwise discriminant analysis on the clinical variables at pre treatment assessment to find the variables for discriminating between high end-state function(HES) and low end-state function(LES). Results: After GCBT, 82.6% of panic patients maintained high end-state functioning at 12 months follow-up. The results of discriminant analysis showed that BDI and BSQ at pre treatment assessment were significant variables to predict end-state functioning at 12 months follow-up. The hit ratio of discriminant analysis was 69.2%. Conclusion: These results suggest that the therapeutic effect of GCBT can be maintained through 12 months. Especially, it is likely that patients who were less depressed and who had less experienced the fear of physical symptoms at pre-treatment can maintain HES.

Cognitive impairment and Alzheimer's disease are serious social problems associated with the rising elderly population in Korea. 1,2,3,4,6-Penta-O-galloyl-β-ᴅ-glucopyranose (PGG) is a gallotannin isolated from medicinal plants such as Rhus chinensis. This study was performed to evaluate the effect of PGG on biomarkers related to cognitive function in human neuroblastoma SK-N-SH cells. Inhibition of acetylcholinesterase (AChE) activity is considered to be one of the main therapeutic strategies. PGG inhibited AChE activity in the test tube as well as in SK-N-SH cells. In addition, PGG induced protein and mRNA expression of brain-derived neurotrophic factor (BDNF), which is a mammalian neurotrophin that plays major roles in the development, maintenance, repair, and survival of neuronal populations. As one of the underlying molecular mechanisms that induce BDNF expression, PGG induced the activation of Ca²⁺/calmodulin (CaM)-dependent protein kinase II (CaMKII)-cAMP response element binding protein (CREB) pathway. In conclusion, PGG may be an useful material for improving cognitive function.
