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.

The purpose of this study was to evaluate the effect of dual-task training with cognitive effort on the walking and balance functions of chronic stroke patients. The study included 14 chronic stroke patients, who were randomly divided into the experimental group (EG) and control group (CG), each with 7 patients. The EG performed the dual-task training with cognitive effort 3 times a week, 30 minutes for 4 weeks, where as the CG performed single-task training three times a week, for 30 minutes for 4 weeks. Outcome assessments were made with 10 m walk test, timed up and go test, 6 minutes walk test, and Berg balance scale. In within-group comparison, subjects from the EG showed significant differences in all variables (p<.05), while subjects from the CG showed only significant differences in 6 minutes walk test, and Berg balance scale (p<.05). Further, there was significant difference in the improvement rate of 10 m walk test. The findings suggest that the dual-task with cognitive effort may be beneficial for improving walking and balance functions of patients with chronic stroke.

Globalization has led to a dramatic increase in intercultural service encounters between services providers and customers from diverse cultural backgrounds. This paper explores the causal relationship between service employees‟ cultural intelligence and adaptive sales behavior in intercultural service encounters, and the mediating effect of cognitive and emotional empathy on this relationship. A quantitative survey methodology was utilized to collect data on 341 salespeople at duty-free shops located on Jeju Island, Korea. Data analysis was conducted using SPSS 18 and Amos 18. The results show that cultural intelligence has a significant impact on cognitive empathy, emotional empathy, and adaptive sales behavior. Cognitive empathy has a positive impact on adaptive sales behavior, whereas the relationship between emotional empathy and adaptive sales behavior is not significant. Additionally, cognitive empathy mediates the relationship of cultural intelligence and adaptive sales behavior. This study has useful managerial implications for employee selection, training, and development in service firms engaged in intercultural service encounters. This study extends prior research on intercultural service encounters by exploring the direct impact of cultural intelligence on intercultural adaptation and the mediating effect of empathy, suggesting the presence of a cognitive mechanism that plays a key role in the impact of cultural intelligence on adaptive sales behavior.

Purpose: This study aimed to investigate factors affecting frailty by age groups among vulnerable elders in Korea. Methods: In this secondary analysis, data were collected from records for 22,868 elders registered in the Visiting Health Management program of Public Health Centers in 2012. Health behaviors, clinically diagnosed disease, frailty, depression and cognitive condition were assessed. Data were analyzed using stepwise regression to determine the associated factors of frailty by age group. Results: Alcohol consumption, physical activity, number of diseases, DM, CVA, arthritis, urinary incontinence, depression and cognitive condition were found to be factors significantly associated with frailty among the elders aged 65~74 (F=135.66, p <.001). Alcohol consumption, physical activity, CVA, arthritis, urinary incontinence, depression and cognitive condition were found to be factors associated with frailty in the elders aged 75~84 (F=245.40, p <.001). Physical activity, CVA, arthritis, depression and cognitive condition were factors associated with frailty in the elders over 85 years of age (F=96.48, p <.001). Conclusion: The findings show that frailty of elders and associated factors were different by age group, and common factors affecting frailty were physical activity, CVA, arthritis, depression and cognitive condition. Thus, these factors should be considered in the development of intervention program for care and prevention of frailty and program should be modified according to age group.
