The purpose of this study was to understand educational changes and effects of cognitive behavioral art therapy using the smart device. The participant of the study was a 4th grade of male elementary school student who had aggressiveness and impulsiveness with emotional instability. The study was conducted one to two times a week for six months with a total of 30 educational sessions. Among 80 minutes per session, 60 minutes of art therapy and 20 minutes of cognitive behavioral therapy were applied, and during the sessions, cognitive action art therapy (drawing and shaping activities), cognitive restructuring, behavioral modification, systemic dullness, social skills training, empathy and landscaping training were applied. For the numeral assessment, Traffic Anxiety Inventory for Children (TAIC), Beck Anxiety Inventory (BAI) and emotional instability measures were used. Research showed that cognitive behavioral art therapy using smart devices had the effect of positive emotional change in children with emotional anxiety, and based on this, future development directions including systematic instructional design, scientific analysis and feedback technologies were discussed.

This study examined the influences of cognitive conflict and non-cognitive variables induced by a discrepant event on process of conceptual change, and the processes that a discrepant event lead to situational interest. Seventh graders participated in this study. A preconception test was administered to select students possessing misconceptions about density. The tests of cognitive response and situational interest to a discrepant event were administered. After learning with a CAl program, the tests assessing attention and effort allocated to the CAl, and conceptual understanding were also administered. A path analysis revealed that cognitive conflict induced by a discrepant event caused situational interest, which in turn increased attention and/or effort and thus, resulted in conceptual change. The results of the path analysis on the processes in which a discrepant event led to situational interest suggested that novelty may be a primary source of situational interest. Novelty influenced situational interest directly as well as through attention demand, exploration intention, and instant enjoyment. Moreover, novelty exerted a direct effect on challenge, which in turn had negative effects on instant enjoyment directly as well as through cognitive conflict, and thus, decreased situational interest. However, the path coefficients of the latter were relatively smaller than those of the former. Educational implications are discussed.

The purpose of this study is to examine the effect of care workers' assistance services on behavioral changes of the elderly. To achieve this, a survey was carried out on 100 elderly people, who receive the services from care workers in J area-based elderly care facilities, and elderly patient families. The results of this study are as follows. First, the effect of care workers' assistance services on the elderly's satisfaction of physical activities showed that the nursing and caregiving services have a significant positive effect on their satisfaction of physical activities(p<.05). Second, the effect of care workers' assistance services on the elderly's satisfaction of psycho-emotional activities showed that the caregiving services have a significant positive effect on their satisfaction of psycho-emotional activities(p<.01). Third, the effect of care workers' assistance services on the elderly's satisfaction of social cognition activities showed that the caregiving services have a significant positive effect on their satisfaction of social cognition activities(p<.01). Consequently, if the elderly receive the repetitive and continuous nursing and caregiving service in the limit that is forced to deteriorate the elderly's physical, psychological and cognitive development, and slow down their activities, there will be changes and promotion in their physical, psychological and cognitive behaviors. In other words, it is of use in that care workers' continuous assistance services can improve the elderly's life, driven by the changes of their physical, psychological and cognitive behaviors.

Geriatric depression is associated with pathological changes in the brain and increases the risk of cognitive impairment or dementia. However, high cognitive reserve, such as high education, can delay or minimize clinical manifestations of pathologies involving the brain, so the effect of geriatric depression on cognitive impairment or dementia may vary depending on the education level. In this study, the author analyzed data from the Korean Longitudinal Study of Aging (KLoSA) to examine whether the effect of geriatric depression on cognitive function differed depending on education level. Among the 10,254 subjects registered in the KLoSA, the 4,905 subjects who met the inclusion criteria were analyzed by stepwise regression analysis. The results were as follows: first, depressive symptoms predicted low cognitive function after 12 years; second, the negative effect of depressive symptoms on cognitive function after 12 years was higher in the old adult group than in the young adult group; and third, the effect of age was significant only in the low-educated group. These results suggest that depressive symptoms in low-educated old adults may increase the risk of development of dementia in the long term.

The purpose of this study is to analyze how a well-structured cognitive reflection journal can affect a learner's metacognition and learning achievement in the area of Engineering Education. The objects of this study were 143 students in total (experimental group: 52, control group: 91) who are taking the 'Fundamental Semiconductor Engineering' course in the Engineering Department at D college in the metropolitan area. For his particular study, we undertook three steps as follows. First, we verified that the two groups of students were equal in areas of metacognition and learning achievement. Second, the experimental group was asked to keep writing the well-structured reflection journal for four weeks and the control group was not. Third, we evaluated the metacognition and learning achievement. This study used a questionnaire to measure metacognition by Sperling(2002) in a Korean translation as well as a well-structured cognitive reflection journal. As a result, we found that the well-structured cognitive reflection journal affects learners positively in the sense of metacognition ability, continuity as well as learning achievement.

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.

Background: Cognitive deficit by hypoxia and/or hypercapnia is one of neuropsychological impairments frequently observed in patients with chronic obstructive pulmonary disease (COPD). The degree of cognitive deficit is variable among patients with similar level of hypoxia and/or hypercapnia, although a cause of this individual difference is well not known. COPD can be divided into two characteristic clinical entities including predominant emphysema and predominant bronchitis. This study was designed to evaluate the individual difference in cognitive deficit respond to hypoxia and/or hypercapnia in patients with COPD. Method: Sixteen patients with COPD (9 emphysema-dominant and 7 bronchitis-dominant) participated in this study. On admission arterial blood gas analysis and trail-making B (TMB) test for the evaluation of cognitive function were done in all patients. Mean TMB scores and the correlations between TMB scores and arterial blood gases were compared between two clinical groups. Results: 1) Mean TMB scores and arterial blood gases between two clinical groups were not different. 2) There was a tendency to be higher TMB score in hypoxemia, acidemia, and hypercapnia. However these findings were not statistically significant. 3) In emphysema-dominant group, $PaCO_2$ was mostly well correlated with TMB score (r=0.693). 4) In bronchitis-dominant group, arterial pH was mostly well correlated with TMB score (r=-0.526). Conclusion: Our data suggest that the individual difference in cognitive deficit respond to hypoxia and/or hypercapnia in patients with COPD may be dependent on their clinical entities, and arterial blood gases mostly well correlated with cognitive function that may be different according to their clinical entities.

최근 통신 기술의 발달로 온라인을 통한 대규모 콘텐츠의 유통이 가능해졌으나, 사용자들은 수많은 콘텐츠 사이에서 원하는 정보를 찾는 시간이 단축되는 것을 원했다. 이로 인해 다양한 분야에서 개인화된 콘텐츠를 추천해주는 추천 시스템(recommendation system)에 대한 요구가 점차 높아졌다. 그럼에도 불구하고 시니어를 위한 추천 시스템에 대한 연구는 매우 부족하다. 또한, 시니어 세대의 변화에 따라 시니어 관련 콘텐츠 연구도 다양하게 진행되고 있으나, 스마트 기기 및 서비스가 젊은 층에 친화적으로 개발됨으로써 시니어 층의 접근성을 감소시키고 있다. 이에 본 연구에서는 다양한 신체적 변화를 겪는 시니어 세대 위해 추천 시스템에서 인지반응 데이터를 이용하여 콘텐츠를 시청하기 적합한 환경을 제공함과 동시에 활동 이력을 중심으로 개인화 추천 시스템을 설계하여 시니어 사용자들의 개념 변화(concept drift) 문제로 사용자가 원하지 않는 콘텐츠를 추천받을 가능성을 줄일 수 있도록 한다.
