  • Based on Nisbett and his colleagues' theoretical model "Holistic" and "Analytic" which show the differences in cognitive style of Eastern Asian and Westerners, the author hypothesized that the differences in cognitive style of people from diverse cultural backgrounds may influence their perception and usage of webpage. An experiment was carried out and the Eye-gaze device was used to assist to explore the relationship. The results revealed the relationship between cognitive style and webpage design. different cognitive style results different viewing pattern on webpage. Chinese people are more likely to have a holistic view of the whole page first and then focus on detail, while French people tend to read the heading information first and then proceeding down the page. Chinese emphasized the background as well as the whole look and feel of the webpage more, while French noticed the independent contents and element designs more on the webpage.

  • FCM(Fuzzy Cognitive Map) is a fuzzy signed directed graph for representing causal reasoning which has fuzziness between causal concepts. Authors have already proposed FCM-based fault diagnostic scheme. However, the previously proposed scheme has the problem of lower diagnostic resolution. In order to improve the diagnostic resolution, a new diagnostic scheme based on extended FCM which incorporates the concept of fuzzy number into FCM is developed in this paper. Furthermore, an enhanced TAM(Temporal Associative Memory) recall procedure and pattern matching scheme are also proposed.

  • Objectives: The purpose of this study was to identify the needs of bio-signal devices for the diagnosis, assessment, and analysis of neurocognitive disorder in Korean medicine (KM) hospitals and clinics. Methods: A questionnaire was developed to survey the current status of medical device use, and diagnosis and interventions for patients with cognitive disorders in KM hospitals and clinics. November 11~December 2, 2019, 114 responses (71.9% completed) were collected by internet-based questionnaires from the members of the Korean society of Oriental Neuropsychiatry. Results: The clinical requests were in the descending order of hematology analyzer, ultrasound imaging system, and electroencephalography among the 15 most commonly used devices of which research would support for their clinical usability. The biosignal-based devices showed the highest research demands for patients with mild cognitive impairment rather than more severe stages of cognitive impairment. Prevention rather than diagnosis, or several treatment regimens was the strongest clinical area of the KM for patients with neurodegenerative cognitive impairment. Many responded that five to 10 minutes of test duration and 20,000 won to 30,000 won of cost would be appropriated for a new device to be developed. Conclusions: There were strong demands for the development of bio-signal devices for neurocognitive disorders among the KM doctors. Specifically, it showed high needs for the technology that can be used in the prevention area of cognitive disorders. Additionally, new medical devices to assess cognitive functions and to obtain KM pattern-related information were the high needs.

  • This study was performed to develop cold-heat and deficiency-excess pattern identification for dementia, as well as for standard Korean medicine diagnosis and treatment. Five experts comprised of 4 neuropsychiatrists of Korean medicine and 1 statistician to develop cold-heat and deficiency-excess pattern identification for dementia. We searched studies about pattern identification and selected 507 articles using Oasis search terms provided by the KIOM. As a result, 10 pattern identification research study were recruited. Moreover, we analyzed neuropsychological assessments for dementia that evaluate Behavioral and Psychological Symptoms of Dementia (BPSD) and cognitive function using experts conferences and we selected neuropsychological instruments using pattern identification. Six cold patterns, six heat patterns, ten deficiency patterns, and four excess patterns were identified according to the cold-heat and deficiency-excess pattern identification of dementia. We selected the Caregiver-Administered Neuropsychiatric Inventory and the Korean Mini-Mental State Examination as neuropsychological assessments of dementia, which examine behavioral symptoms and cognitive function, suspectively. We formed positive and negative correlation between Korean medicine pattern identification and neuropsychological assessments for dementia. We developed and suggested a forecast module of pattern identification for dementia. But, it is necessary to perform additional clinical trials to verify its validity and accuracy.

  • Objectives : Cognitive therapy is the most extensively researched psychological treatment for nonpsychotic unipolar outpatient depressive disorders. This review focused on the utility of this approach in severe or chronic depressive disorders, in relapse prevention and also on the potential benefits of combining cognitive therapy with medication. Methods : The author reviewed original studies and quantitative analyses on the effects of cognitive therapy, predictors of response, and neuroimaging studies of cognitive therapy in major depressive disorder. The sources used for the literature search were data bases : PubMed, EMBASE, CDSR on the internet, references in papers or books. Results : This review suggests that cognitive therapy is as effective as antidepressant medication in severe depressive disorders. And cognitive therapy can be an effective alternative to antidepressant medication. Patients benefited significantly more from combined cognitive therapy and antidepressant treatment than from either treatment alone. Most importantly, the addition of cognitive therapy to usual treatment appears to protect against future relapse in individuals known to be at high risk of repeated episodes of depression. In addition, subjects who received cognitive therapy showed significantly greater improvements in chronic depression than receiving antidepressant medication. Pooled data suggests that there is a significant relationship between the therapist's level of training or experience, the type of therapy used and patient outcome. Recent functional imaging studies examining brain changes following cognitive therapy report a variety of regional effects, but there is no consistent pattern across the few published studies. Conclusion : Cognitive therapy has proved beneficial in treating depressive patients. Despite empirical data supporting its efficacy, there are still problems in gaining access to cognitive therapy in clinical practice.

  • The relationship between cognitive function and dietary patterns in Korean elderly women was investigated in this study. Twenty-four-hour dietary recall and cognitive function tests were performed in 170 elderly women aged over 60 years. Average age of the subjects was 71 years and the average number of family members was 3.3. Most of the subjects had less than seven years of education and their monthly income was much lower than the Korean average. Most of the subjects engaged in regular exercise and did not indulge in drinking and smoking. The average cognitive function score of the subjects was 58.4. Most of the subjects appeared to consume insufficient amount of food ; average intakes of energy, Ca, iron, vitamin A, and riboflavin were lower than RDA for the elderly. Cognitive function score was positively related to education level and regularity of exercise. Also, cognitive function score had a strong relationship with food intake such as total amounts of foods, fish and shellfish, milk and dairy products, total animal food, fruit, bread and sugar. Energy, protein, Ca, p, riboflavin, and niacin were also shown to have positive relationships to cognitive function score, while carbohydrate caloric ratio had a negative relationship with cognitive function. According to the results of multiple regression analysis, factors that most influenced on cognitive function were education level and riboflavin intake. The subjects who had more than seven years of education had significantly higher cognitive function scores than those with no school education. And cognitive function scores f3r those who consumed more than 2/3 of the RDA for most nutrients were significantly higher than the ones fir the subjects who consumed less than 2/3 of the RDA. These results suggest that proper education and adequate nutrient intake in quantity and quality by achieving food diversity are essential in maintaining cognitive function in later life (Korean J Nutrition 31(9) : 1457-1467, 1998)

  • The purpose of this study is to analyze the relationship between the self-leadership and the cognitive flexibility of the university students who are majoring in dance to provide useful information in the field of dance instruction. Participants were the students majoring in dance who are enrolled in the dance department of the four-year universities nationwide and 282 data have been used for the final analysis. The analytical method for verification of hypothesis was multiple regression analysis to be performed at a significance level of ${\alpha}$=.05. As the result, the following conclusions have been gained. First, the constructive thinking pattern among the sub-factors of self-leadership had a positive influence on the flexibility of preferred varieties which is a sub-factor of cognitive flexibility. However, the behavior-oriented and natural reward self-leadership did not have influence on the diversity preferred flexibility. Second, the natural reward and constructive thinking pattern among the sub-factors of self-leadership have positive influence on the flexibility of preferred complexity which is a sub-factor of cognitive flexibility while the constructive thinking pattern flexibility was shown as exercising a very powerful influence. But the behavior-oriented self-leadership did not have influence on the flexibility of preferred complexity.
