Purpose: This study aimed to determine the effects of sensory feedback training of the ankle with visuoperceptual stimulation on static balance and gait functions in patients with chronic post-stroke hemiparesis. Methods: This study included 16 patients with chronic post-stroke hemiparesis. The subjects were randomly assigned toeither the experimental group (EG) or the control group (CG), with 8 subjects in each group. All the subjects received a routine physical therapy. The EG subjects received a 30-min sensory feedback training for the foot and ankle with visuoperceptual stimulation by using Tetrax Portable Multiple System. This training was conducted 3 times a week for 4 weeks. The scores of balance ability, timed up and go (TUG), and dynamic gait index (DGI) were assessed before and after the intervention. Results: In the EG, the scores of static balance, TUG, and DGI obtained afterthe intervention significantly differed from those obtained before the intervention (p<0.05). Further, in the EG, a significant difference was noted in the rate of change of all the variables when compared with those of the CG (p<0.05). However, in the CG, post-intervention score were only significantly different for DGI. Conclusion: Our findings indicate that the sensory feedback training with visuoperceptual stimulation improves balance and gait functions of patients with chronic post-stroke hemiparesis. Further studies are needed to generalize the results of this study.

Purpose: The purpose of this study was to determine correlations between the Berg Balance Scale (BBS), Functional Reach Test (FRT), Timed Up & Go (TUG), Motor-Free Visual Perception Reach Test Vertical format (MVPT-V), Functional Independence Measure (FIM). Methods: The subjects used in this study were 35 stroke patients from Cheongju ST. Mary's hospital. Balance was measured by BBS, FRT. Functional mobility was measured by TUG. Visual perception was measured by MVPT-V. FIM was used to evaluate the activities of daily living. Data was analyzed using pearson product correlation. The TUG and MVPT-V index were analyzed by linear regression. Results: There was a statistically significant difference between FRT and BBS (r=0.89, p<0.01), FIM (r=0.74, p<0.05), MVPT-V (r=0.40, p<0.05), and TUG (r=-0.36, p<0.05). There was significant statistical differences between TUG and MVPT-V (r=-0.64, p<.01). However, statistically significant differences were observed between BBS and FIM (r=0.79, p<0.01). The visual close item of the MVPT-V showed the strongest variance in predicting TUG. Conclusion: The use of both quantitative and qualitive scales was shown to be a good measuring instrument for the classification of general clinical performances of stroke patients. In particular, the results suggest that the visual perception test may be able to predict functional locomotion in stroke patients.

Purpose : There is a lack of research on this field in the Republic of Korea, especially those that have seen the effect of interaction between transcranial direct current stimulation and computerized cognitive rehabilitation therapy. This study divided 30 dementia patients into a treatment group, which received transcranial direct current stimulation and computerized cognitive rehabilitation, and a control group, which received pseudo-transcranial direct current stimulation and pseudo-computerized cognitive rehabilitation. This study evaluated the effects of these treatments on the visual perception, cognition functions, and daily activities of dementia patients. Methods : Fifteen subjects were allocated to the treatment group and the other 15 subjects were allocated to the control group. Treatments were given at intervals of five sessions per week (30 minutes per session) for six weeks (30 times in total). This study used the Neurobehavioral Cognitive Status Examination (NCSE) to examine cognitive functions, MVPT to evaluate visual perception, and FIM to test daily living activities before and after applying the treatments. Results : The results of this study showed that cognitive functions, visual perception, and daily living activities significantly (p<.05) improved after the intervention in the treatment group and the control group. The changes in cognitive functions, visual perception, and daily living activities due to the treatments were significantly different between the groups (p<.05). Conclusion : The results indicated that transcranial direct current stimulation and computerized cognitive rehabilitation therapy improved visual perception and daily living activities by increasing cognitive functions. Consequently, it was found that the simultaneous application of transcranial direct current stimulation in conjunction with a computerized cognitive rehabilitation program was an intervention method that could positively affect the visual perception, cognitive function, and daily living activities of dementia patients. Based on the results of this study, the study of arbitration protocols for demential will have to be more active.

The purpose of this study was to analyze the effect of infographic instruction to promote the use of the scientific model in the 'lens' unit of elementary science textbooks. The participants were $6^{th}$ grade students(n=53) of G elementary school in G city, Gyeongsangnam-do. For this study, the lesson plan of the 'lens' unit consisted of three steps as investigation of students' prior concept about the lens, scientific model construction activity, and infographic construction activity. We then analyzed the results of this study from three perspectives: the scientific concept, scientific model, and infographic. Before the lesson, students focused on the external shape and material of the lens in prior concept of it. However, after the scientific model construction activity and infographic construction activity, students' scientific concept about the lens improved in the categories of features of lens, features of glasses, light path, and applications of the lens. In terms of the scientific model, use of type and frequency of scientific model increased more in the infographic construction activity than the scientific construction model activity. Also, in terms of infographic, the two infographic types as function based infographic and connection based infographic used more than non-infographic in the infographic construction activity. Also, the frequency of Gestal theory's visual perception increased more in the infographic construction activity than the scientific model construction activity.

This study systematically analyzed computer-based driving intervention programs for seniors, to provide the academic background for driving intervention for seniors. Articles published from January 2009 till December 2018 were researched and analyzed. 'PubMed, Google Scholar, and Science Direct' were used to search articles published overseas, and 'RISS, KERIS, and KISS' searched for articles published in Korea. Based on the inclusion and exclusion criteria, totally 359 papers were retrieved, and 10 articles were finally analyzed; 8 articles (80%) were evidence level I, and 2 articles (20%) were evidence level III. Amongst the computer-based interventions, driving simulators (70%) were the most common, followed by two video image training (20%) and one Nintendo Wii program (10%). In most studies, driving simulators trained the cognitive and visual abilities of seniors and enhanced their abilities to cope with risk situations under various simulated circumstances. Other interventions were also reported to have a positive effect. For evaluating elderly drivers, the driving performance evaluation using a driving simulator was the most common; in addition, evaluations of attention, space-time ability, cognitive function, risk perception, depression and anxiety were also commonly used. We believe that it is appropriate to employ computer-based driving intervention programs for seniors to train and evaluate various domains. We expect that these interventions can be used as an effective tool for safe driving.
