In recent years, the privacy concern for mobile consumers is emerging as the use of mobile application(apps) is growing according to the rapid spread of mobile devices such as smart phones and tablet PCs. To improve privacy protections in the mobile communications and apps, overseas organizations are announcing guidelines and/or checklists for stake holders. Although personal information protection guidelines for application developers have been prepared in the country, efforts to improve consumer privacy capability is insufficient. Thus, in this paper we first scope the app privacy related guidelines in both domestic and foreign affairs, then present the risk factors of privacy invasion by the stage of mobile application use based on the "Privacy Protection Act", offering privacy checklists for consumers. This checklist will enhance the self-management capability of consumer privacy and create virtuous cycle in the mobile ecosystem.

In this paper, we analyzed whether there exists positive relation between firm's global activity and various innovation output and, if it exists, what are the major factors by which innovation outputs can be generated, focusing on the different degree of global activity. We found that for foreign MNC affiliates, their superior information access to existing knowledge is much more important and for non-MNC exporters and domestic MNC parents not only access to existing knowledge but also active investment in new knowledge is important. When we analyze the product and the process innovation separately, we found that for the process innovation information flows from existing knowledge is relatively more important while for product innovation investment in new knowledge and information flows from existing knowledge are almost equally important. Thus in Korea policies that promote both direct R&D activities and information flows should be pursued at the same time to enhance firms' innovativeness.

The purpose of this study is to investigate the determinants of the SNS usage time depending on SNS motive of the youth workers. Although previous studies revealed that there are many motivations for SNS usage, it is not known which factors determine usage time of each SNS motive. In this study, we constructed the unbalanced panel data of the Korean Education & Employment Panel data. Among three different SNS motives such as information exchange, social networking, and fun pursuit, gender, physical health, extraversion, and conscientiousness affected the usage of SNS when the motivation was information exchange. When it was personal connection, the size of organization, education, physical health, subjective happiness, job satisfaction, neuroticism, and agreeableness did. When it was fun & interest, foreign company, status of children, subjective happiness, and job satisfaction did. Based on the findings, we discussed theoretical and practical implications.

The purpose of this study was to investigate the convergence factors affecting of physical activity level on hemodialysis patients' depression, health-related quality of life and sleep disorders. The participants were 193 hemodialysis patients undergoing hemodialysis in five hospitals in two cities. Data were analyzed by technical statistics, correlation and hierarchical regression. The results showed that depression and physical activity were negatively correlated (r = -.259, p <.01), and physical and mental health related quality of life and physical activity correlated positively (R = .273, p <.01, r = .186, p <.01), respectively. Hierarchical regression analysis showed that the higher the quality of life related to physical health, the higher the level of physical activity of hemodialysis patients (${\beta}=.22$, p <.01). Therefore, it is required to develop an intervention program to improve health-related quality of life by improving the physical activity of hemodialysis patients.

Purpose - The purpose of this paper is to analyze the trade structure and competitiveness of China's information technology (IT) industry in comparison to that of Korea and the United States, particularly in terms of quality. Design/methodology/approach - Indices such as trade specialization index (TSI), Revealed Comparative Advantage (RCA), and Market Comparative Advantage (MCA) are used. Further, an Intra-industry Trade (IIT) index is used to analyze qualitative changes in horizontal intra-industry trade and intra-industry trade of high- and low-quality goods. Findings - China's IT industry has a comparative competitive advantage over that of Korea and the United States, and mainly exports goods of inferior quality and imports goods of superior quality. Further, China's horizontal intra-industry trade has been decreasing, while its vertical intra-industry trade has been increasing and vertical trade of inferior quality goods outweighs that of superior quality goods. This shows that China is rapidly catching up with Korea and the United States, even though its qualitative competitiveness has not significantly improved. Research limitations/implication - This study has academic and political implications, as it analyzes changes in China's IT trade competitiveness. However, it is somewhat limited as factors determining qualitative aspects has not been considered. Originality/value - Most studies aggregate analyses of export competitiveness using methodologies such as TSI, RCA, and market share. However, the focus of these methods is price competitiveness. Hence, an examination of the objective and qualitative trade competitiveness of China's IT industry is necessary. this study the trade structure and quantitative competitiveness of the industry by analyzing intra-industry trade focusing on the quality of competitiveness. Therefore, the changes in China's IT industry in the USA and Korea and in foreign trade competitiveness and quality competitiveness are clarified. The results show that the academic and policy implications of these changes in the IT industry will be a useful resource. This is the first study in Korea to attempt such an analysis. This is the first study in Korea to attempt such an analysis.
