Purpose: This study was done to identify differences in factors influencing cognitive function according to the cognition of community dwelling elders. Methods: A convenience sample of 565 community dwelling elders participated in this study and from May to June, 2010 trained research assistants collected data using structured questionnaires. Collected data were analyzed using descriptive statistics, t-test, one-way ANOVA, correlation, and multiple regression with the SPSS Win 15.0 version. Results: The elders had a slightly low degree of cognitive function. Of the 565 elders, 41.1% were in the normal group for cognitive function and 58.9% in the mild impairment group. Although there were no significant differences in general characteristics between the groups, factors influencing cognitive function were different. Factors influencing elders in the normal group were leisure activity and moderately good health status. These variables accounted for 5.7% of the variance in cognitive function. Factors influencing elders in the mild impairment group were leisure activity, depression, and education level limited to elementary school graduation. These variables accounted for 19.9% of the variance cognitive function. Conclusion: This study provides comprehensive understanding of factors influencing cognitive function in elders. Differentiated nursing interventions according to degree of cognitive function are suggested.

This study was designed and undertaken to find out the degree of powerlessness, perception of health and cognitive level of elderly home residents and to determine the factors influencing powerlessness, perception of health and cognitive level. The data were collected from October 1st to 20th, 1998. The subjects in this study were 271 elderly home residents over the age 60 living in Taejon city. The study tool for measuring powerlessness was developed by S.E. Chung(1998), the other for measuring perception of health was a self-rating scale defined by Mossey & Shapiro (1982), and the tool for measuring cognitive level was developed by Kahn, Goldfarb, Pollack and Peck(1960). Data were analysed for percentage, mean, t-test, and ANOVA using the SPSS program. The results of this study were as follows ; 1. The degree of powerlessness, perception of health and cognitive level was scored above the median. 2. The degree of the elderly' powerlessness was statistically significantly different in three demographic variables; sex, one's state of health compared to other elderly' and living expense load. 3. Perception of one's health was statistically significantly different in four demographic variables; sex, marital status, educational level and monthly money. 4. Cognitive level of the elderly was statistically significantly different in three demographic variables; age, educational level and one's health of state compared to other elderly' health. In conclusion, the factors influencing the elderly' powerlessness, perception of health and cognitive level generally were age, sex, their economic independence, marital status, and educational level. Also, this study indicates that social welfare for the elderly could be effective in reducing their powerlessness and enhancing their health of state and cognitive level.

학생들의 물리 오개념을 과학적으로 변화시키기 위한 학습전략 중 하나는 학생들에게 인지갈등을 유발시키는 것이다. 인지갈등전략의 핵심적 방법은 학생에게 불일치 상황을 제시하는 것이다. 그런데 학생들이 불일치 현상을 대면하기 전에 자신의 개념을 탐색하고 진술하는 단계에서도 인지갈등을 경험한다는 사례가 보고된 바가 있었다. 이 연구에서는 불일치 현상을 대면하기 전에 유발되는 인지갈등정도를 조사하고 그 인지갈등이 불일치 현상 대면 후에 유발되는 인지갈등과 개념변화에 어떠한 영향을 미치는지 알아보고자 하였다. 이 연구는 광원과 무중력 개념을 소재로 한 교실 수업으로 진행하였다. 연구대상은 부산 소재 중학교 2개교의 학생들이었다. 수업과정에서 사전개념, 대면 전과 후 갈등정도 및 사후개념을 조사하였다. 수업 3주후에는 지연사후개념을 검사하였다. 그 결과 불일치 현상 대면 전의 인지갈등 평균은 대면 후의 인지갈등 평균과 차이가 없었으며 두 인지갈등 사이에는 정적상관이 있었다. 불일치 현상 대면 전과 후의 인지갈등정도가 모두 개념변화정도와 정적상관이 있었는데, 두 인지갈등 중 개념변화를 주도적으로 설명하는 것은 불일치 현상 대면 전의 인지갈등정도였다.

Objective Motor, perceptual, and cognitive functions are known to affect driving competence. Subcortical ischemic changes on brain magnetic resonance imaging (MRI) can reflect reduction in cognitive and motor performance. However, few studies have reported the relationship between subcortical ischemic changes and driving competence of the elderly. Thus, the objective of this study was to investigate the association between subcortical ischemic changes on MRI and driving abilities of the elderly. Methods Participants (n=540) were drawn from a nationwide, multicenter, hospital-based, longitudinal cohort. Each participant underwent MRI scan and interview for driving capacity categorized into 'now driving' and 'driving cessation (driven before, not driving now)'. Participants were divided into three groups (mild, n=389; moderate, n=116; and severe, n=35) depending on the degree of white matter hyperintensity (WMH) on MRI at baseline. Driving status was evaluated at follow-up. Statistical analyses were conducted using ${\chi}^2$ test, analysis of variance (ANOVA), structured equation model (SEM), and generalized estimating equation (GEE). Results In SEM, greater baseline degree of WMH was directly associated with driving cessation regardless of cognitive or motor dysfunction (${\beta}=-0.110$, p<0.001). In GEE models after controlling for age, sex, education, cognitive, and motor dysfunction, more severe change in the degree of WMH was associated with faster change from 'now driving' state to 'driving cessation' state over time in the elderly (${\beta}=-0.508$, p<0.001). Conclusion In both cross-sectional and longitudinal results, the degree of subcortical ischemic change on MRI might predict driving cessation in the elderly.
