As a result of the recent development and dissemination of HMD equipment, there has been an increase in the development of virtual reality contents. However most of these developments do not take differences of users' cognitive abilities and users' ability to immerse in and connect to these contents into consideration. In this study, we investigated the effects of visual factors of contents by conducting literature reviews, and conducted research on the correlation between visual factors and Virtual reality presence. While color and spatial factors had significant positive effects on content recognition and sense of reality, motion perception factors caused cognitive dissonance, which negatively effects the accurate recognition of contents. We were able to find that accurate recognition of virtual reality contents have a great impact on users' sense of reality.

Objective: This study was conducted to investigate the correlation of cognitive function and fall-risk behavioral factors. Methods: The elderly over than 65 year-old with and without cognitive impairment were recruited in four different regional areas. Total 43 data of K-MoCA and FaB were collected. Pearson correlation of total scores of K-MoCA and FaB was analyzed using SPSS 22. Correlation between total score of K-MoCA and each item of FaB which describes the fall-risk behaviors was analyzed as well. Results: The cognitive function was statistically positive correlated with the fall-related behaviors in pearson correlation analysis (p<.01). Nine items of total 30 items of FaB was significantly correlated with total score of K-MoCA. Conclusion: Fall-risk behaviors were decreased as the cognitive level was improved. If the cognitive function was vulnerable, the insight to fall-risk behaviors deficits and various fall-related behavioral factors exits. The high fall-risk behaviors were correlated with cognitive function, so that the cognitive level should be considered in fall prevention intervention in Occupational Therapy.

In this article, we conducted a literature review about cognitive aging and social-psychological factors that influence cognitive function in old age. As getting older, cognitive function was mostly seen as declining, even though the effect of aging is differential across domains of cognitive ability. The negative view about cognitive aging might be reflecting social-psychological factors such as age stereotypes. Age stereotypes vary among different cultures, but appear to be negative in general. Negative age stereotypes are related to lower level of memory performances. Older adults who were experimentally presented with positive age stereotypes exhibited better memory performances than those with negative age stereotypes. Self-referent belief, appraisals of one's own cognitive abilities, could also affect actual performance in cognitive tasks. Older adults showed lower self-referent belief than younger adults, and it might explain memory decline in old age. Theoretical explanation and implication about the relationship between social-psychological factors and cognitive abilities were discussed.

Parkinson's disease (PD) is clinically characterized by a variety of motor and non-motor symptoms, including cognitive and neuropsychiatric symptoms. Integrating a large variety of symptoms into a small number of clinical subtypes could be valuable for appropriate and early therapeutic intervention. As a first step toward this aim, this study attempted to identify correlation patterns among motor, cognitive and neuropsychiatric symptoms in PD without dementia. One hundred four non-demented patients with PD underwent a comprehensive motor, neuropsychological, and neuropsychiatric assessments. Factor analysis was performed to identify correlation patterns among demographic, motor, cognitive and neuropsychiatric variables. The eight factors were extracted: 1 motor-related, 3 cognitive-related and 4 neuropsychiatric factors. We indentified that characteristics of correlation can have associated symptom pattern in the disease process of Parkinson's disease. The current results suggest that a broad range of motor and non-motor symptoms in PD may be reducible to a small number of clinical parameters, which may be useful for identifying clinical subtypes of PD for individual patients.

This study analyzed the factors of stress perception and their patterns depending on the high school students from different types of high school, which include academic high schools and vocational high schools. The data reflected the degree of stress perception according to several factors, which are considered to be related to stress perception, and the study analyzed how differently these factors affected students in each school type. The subjects were 29,380 students from the 14th Korea Youth Health Behavior Survey who meet the purpose of this study. The factors related to stress perception were classified into general characteristics, health behavior characteristics, and health status characteristics. The factors of the study were compared in each group and between the groups. In both school types, stress perception was associated with a number of common factors and some group specific factors. The common main factors related to stress perception were depressive experience, subjective recognition of their health status, subjective recognition of sleep satisfaction, and gender. However, the pattern in which each factor was related to stress perception differed according to the school types. Therefore, efforts should be made to reflect the characteristics of each school type while considering the common factors related to stress perception when making policies for managing high school students' stress.
