  • This study was to investigate the effect of eye movement and intentional finger movement on cognitive ability. Normal adult subjects were randomly divided into two groups: saccadic eye movement(SEM) and intentional finger movement(IFM). After 2 weeks of intervention, Digit span was used for short-term memory test and N-back was used for working memory test. As a result, the short-term memory of the IFM group increased significantly over time, and the follow-up test showed difference between group. The IFM group's the execution time, the error count and the accuracy rate of n-back item showed significant effects over time. The SEM group's the execution time and the accuracy of n-back item showed significant effects over time. In conclusion, the IFM method, which is a multiple stimulus that can activate the cerebral cortex more extensively than the single stimulus SEM, may be more useful as an intervention method of cognitive function improvement.

  • This research purposes to find out the mathematical cognitive characteristics of Korean students and compare it with that of TIMSS 2011 high-achieving countries based on the Cognitive Diagnostic Theory. Based on framework and questions of TIMSS 2011, we select cognitive attributes. Using the data of 8th grade students' mathematical achievement in TIMSS 2011, we compare and analyze the top 15-countries students' cognitive traits. As a result, cognition domain of TIMSS 2011 is reclassified as 9 cognitive attributes. we could distinguish between easy attributes and difficult attributes that students in each country relatively think. Especially, Students of Korea relatively think Recall/Recognize, Compute, Classify/Measure and Represent are easy. On the other hand, relatively they have difficulties in Retrieve, Implement, and Generalize. Based on this research result, It is necessary to establish an educational measures for each attributes which students have difficulties.

  • The study looked at the impact on the health of the spine caused by the increasing addiction to smart phones, and examine the moderating effect of adjusting spinal health according to cognitive strength. All subjects used the smartphone by measuring the diagnostic scale of the smartphone addiction, the angle of forward inclination of the cervical spine, and the amplitude variation of the cognitive Gamma-Peak of the brain waves. As a result, as the use of smart phones increases, the spine angle significantly increased (p<0.001), as cognitive strength increased, the spine angle decreased significantly (p<0.01). The cognitive strength also showed the effect of adjusting the spine angle through interaction with the degree of use of a smartphone (p<0.05). This results in a higher degree of smartphone use in lower and middle cognition strength groups, which results in a higher angle of forward tilt in the cervical spine.

  • This study investigated the effects of the cognitive acceleration program devised for accelerating the development of formal reasoning ability of students. ‘Thinking Science’ activities developed by the Cognitive Acceleration through Science Education(CASE) project were implemented to 420 students in 5th grade aged 10+ in four elementary schools over a period of two yea. Homogeneity between the experimental group and control group was tested with SRT II, and the improvement of formal reasoning ability of the students was tested with SRT III. The results were analyzed by treatment, gender, and cognitive levels of the students. Statistically significant gains were shown in the CASE group compared with those in the control group. Cognitive level of girls in the CASE group increased as compared with the control group, while there was moderate effect in boys for the primary school. These results implied that the thinking science activities were effective in cognitive acceleration of girls aged 10+. It was shown that much more CASE students in concrete operational level shifted to formal operational level as compared with the control group while there were no significant effects in the other levels for primary school.

  • This study aims to understand the effects of a Computer - based Cognitive Rehabilitation Therapy(CBCRT) evidence based on mild dementia patients' ability to activities daily living(ADL), cognitive function and measure of occupational performance and to suggest basic data for a cognitive rehabilitation therapy for dementia patients. Method : A CBCRT was applied two times a week for 5 weeks to 14 mild dementia patients who visited Yongin Center for Managing Dementia in Gyeongi-do between February and August 2009. Based on frame of reference for Visual-Perception a CBCRT was applied at home. Moreover, a one group pretest-post test design was, which is a quasi-experiment and research, also applied in order to verify the effects of the rehabilitation therapy on the subjects' ability to ADL, cognitive function and occupational performance skills. Results: A significant effect was confirmed (p<.05) from the CBCRT which Assessment of Motor and Process Skills(AMPS) processing skills and cognitive function and occupational performance skills. Neither was found any significant effect in improving motor skills from AMPS. Conclusion: It seems that a CBCRT based on evidence and has an effect on the improvement of the ability to ADL and cognitive function of mild dementia patients living in a community. The present author hopes that, in the future, more cognitive rehabilitation programs will be developed to improve the functions of mild dementia patients living in a community.

  • This study was performed to investigate the influence of Corporate Social Responsibility (CSR) activity on corporate image and repurchase intention (pre and post measure) after the news of food incident. A questionnaire survey was carried out for 235 college students in Seoul, Korea. The participants were given an instruction with CSR activity of company in food industry and completed the survey. We collected the survey and did the statistical analysis by SPSS. The result of this study was as follows: Significant differences (p < 0.05) were found between the two groups, one was aware of corporation's CSR activity and the other was not. The ranges of score of each question on corporate images after and before providing CSR information were 3.21-3.94 and 3.89-4.62, respectively. Also, the ranges of score of each question on repurchase intention after and before providing CSR information were 3.11-4.64 and 3.60-4.67, respectively. Thus, the result confirms that the previous studies' conclusion which explains CSR can shield consumers' negative attitude toward the company. The finding of this study emphasizes the importance of CSR activity to the companies in food industry and the need for making public awareness of CSR activity.

  • The purpose of this study was to examine the students' responses when students were confronted with anomalous situations in physics. 16 students were selected from one middle school in Busan by examining the pre-test results. To measure students' responses and cognitive conflict levels, written Cognitive Conflict Levels Test(CCLT) developed in a previous study was used together with interviews. Students' responses were tape-recorded. Two kinds of anomalous situations were presented. One was a quantitative demonstration with scale, the other was a qualitative demonstration without scale. In the quantitative group, all students observed anomalous situations correctly. However, in the qualitative group, many of their observations of anomalous situations were incorrect. The students who observed anomalous situations based on preconceptions tended not to abandon their preconceptions, and suggested confirmation experiments which were supposedly to support their preconceptions. The students who recognized results very differently from their preconceptions when confronted with anomalous situations abandoned their preconceptions and suggested alternative experiments. The students who changed their beliefs about preconceptions showed higher cognitive conflict levels than who didn't abandon their preconceptions.
