The purpose of this study is to examine the effect of personal psychological variables(cognitive flexibility, emotion dysregulation, subjective health condition), family variables(marital satisfaction, father-adolescent communication) and job satisfaction on the psychological well-being of middle-aged men. For this research, questionnaires were administered to 550 middle-aged men residing in Seoul, Gyeonggi and Incheon. Among 352 questionnaires collected, 327 were selected and statistically analyzed by average, standard deviation, frequency analysis, t-test, one-way ANOVA, and hierarchical regression analysis using SPSS Win 21.0. The main results of the study are as follows: First, according to middle-aged men's social-demographic variables, the level of their psychological well-being differed significantly. Second, cognitive flexibility was the most significant predictor of their psychological well-being. In addition, emotion dysregulation, job satisfaction, father-adolescent communication, and subjective health condition were significant predictors. These results suggest that cognitive reconstruction training or problem-solving intervention could be useful for the psychological well-being of middle-aged men.

The purpose of this study were to investigate: 1) The level of information-processing competencies of children consumers. 2) The differences of information-processing competencises of children consumers according to the cognitive development stage, the variables related to social learning and the socio-ecomonic variables. 3) The independent influences of variables related to information-processing competencies of children consumers. 4) The independent influences of variables related to information-processing competencies of children consumers according to the cognitive development stage. For these purposes, a survey was conducted using questionaires. The questionaires consisted of mother's and child's were distributed to children of second and 6th grade and their mothers of 5 elementary schools in Seoul 634 cases were selected for data analysis. Then, these data were analyzed with statistical methods such as Frequency Distribution, Percentile, Mean, One-way Anova, Scheff -Test, T-Test, Pearson's Correlation and Multiple Regression Analysis. From these finding, the follawing suggestions are made. First, to improve information processing competencies of children consumers, children consumers should be offered the consumer information that is suitable to child's cognitive development stage. Second, the consumer education and learning practical discriminatory competencies on TV ads. should be conducted for children consumers and his mothers. Third, children consumers should have the opportunities to practice as a consumer. The last, children consumers in low-income should be offered the specially educational program.

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.

For information processing tasks, it is an important cognitive skill to manipulate and store information, which is known as information intake. One of the tasks which greatly involve this skill would be a spreadsheet calculation task. In this study, a spreadsheet calculation task is analyzed by the cognitive task analysis based on the cognitive factors having been usef for a model of human information processing. By the results of the cognitive task analysis, the spreadsheet calculation tasks to be used in the experiments are designed and the testbattery of cognitive abilities assessment (CCAB ; complex cognitive asssessment battery) are selected. Then, the features of cognitive demands and a human performance model of the spreadsheet calculation task are suggested by means of correlation analysis, principal component factor analysis, and regression analysis of the results of the experiments on task performances and the assessment of cognitive abilities. Also, the application of the results of the study to job placement and further research issues are described.

The purpose of this study was to examine the role of cognitive conflict in the conceptual change process. Ninety-seven high school students in Korea participated in this study. Before instruction, we conducted pretests to measure learning motivation and learning strategies. During instruction, we tested the students' preconceptions about Newton's 3rd Law and presented demonstrations. After this, we tested the students' cognitive conflict levels and provided students learning sessions in which we explained the results of the demonstrations. After these learning sessions, we tested the students' state learning motivation and state learning strategy. Posttests and delayed posttests were conducted with individual interviews. The result shows that cognitive conflict has direct/indirect effects on the conceptual change process. However, the effects of cognitive conflict are mediated by other variables in class, such as state learning motivation and state learning strategy. In addition, we found that there was an optimal level of cognitive conflict in the conceptual change process. We discuss the complex role of cognitive conflict in conceptual change, and the educational implications of these findings.

The purpose of this study was to find the effect of these variables on the duration of the momentum effect. To examine the momentum effect for gravitational field concepts, an intensive time series design was used. We collected data every day except Sundays and holidays for 50 days; 5 days for baseline, 30 days for intervention, and 15 days for the follow up We adopted cognitive levels and styles as students characteristics and two item characteristics(quantity versus quality, and word versus picture) as the item representation patterns. In this study, the momentum effect was influenced by students characteristics and item representation patterns. The results showed that two variables, cognitive style and quantity/quality, were the most influential factors for the duration of momentum effect. Field independent students showed a longer duration than field dependent students did. In addition, students showed a longer duration in quality items than in quantity items. However, students cognitive levels(formal or preformal) and word/picture presentations seemed to have relatively weak effect on the duration of the momentum effect.

This study analyzed President Park's speeches and the government's industry policy in the field of information security using cognitive map. The relationship analysis between policy tool variables and policy goal variables was employed to derive revitalization strategy of information security. This paper found that entrepreneurship revitalization has very strong causality with expansion of domestic market and global market. But, on the other hand, HR development has very weak causality with job creation and future growth driver because the labor market in the information security industry is poor and its transfer rate to other industry is very high. This study showed that this cognitive map could be characterized by a scarcity of feedback loops and a strong emphasis on the positive loops in the structure of virtuous circle. In this paper, we also constructed a comprehensive cognitive map on the policy vision of information security, showing that there are a risk of cyber threat, an opportunity of new fusion security market, information security reinforcing circle, global economic circle, and domestic market circle.
