The purpose of this study was to compare the differences in the quality of dietary and life across age groups of Korean adults. According to life cycle, four age groups (20~29, 30~49, 50~64, ≥65) were created. Anthropometric indices showed significant differences according to age group (p<0.001). Energy intake significantly decreased according to age group as a result of decreased protein and fat intake (p<0.001). The intake levels of minerals, vitamins, and dietary fiber per 1,000 kcal were the lowest in the 20~29 age group (p<0.001). Whereas saturated fatty acids, MUFA, and PUFA intake levels were the highest for those in the 20~29 age group (p<0.001). The quality of dietary (DQI-I) increased with age group, but the quality of life (EQ-5D index) decreased (p<0.001). The quality of dietary showed 5.8% explanation power on the quality of life (p<0.001). Additionally, diet moderation was shown as having a negative effect, but the diversity and balance of diets had a positive effect on the quality of life. By age group, the relationship between quality of dietary and quality of life was the highest in ≥65 age group. These results suggest that practical dietary education is needed from the 20's to ensure the quality of healthy life for the elderly.

Amid the growing importance and growth potential of venture firms worldwide, this study aimed to figure out the effect of new product development capabilities (NPDC) on the internationalization of Korean venture firms and the moderating impact of founders' human capital. NPDC is a core competency that can cope with the rapidly changing market environment and is required when entering multinational markets. Therefore, we subdivided founders' human capital into professional experience, startup experience, education level, and marketing capacity and examined each moderating effect on a venture firm's internationalization. As a result of empirical analysis of 1,362 Korean venture firms using the Tobit model, this study found that venture firms with excellent NPDC tend to achieve a higher level of internationalization. In addition, among the founder's human capitals, professional experience, education level, and marketing competency moderated the positive relationship between NPDC and internationalization. In contrast, the founder's startup experience was insignificant. The results of this empirical analysis explain the factors that trigger the internationalization performance of venture firms from the perspective of dynamic capabilities and suggest that the founder's human capital played an essential role in the internationalization.

This study aims to investigate how librarians' loyalty is affected by the organizational structure of libraries. For this purpose, 39 university libraries and 21 public libraries in Seoul were surveyed, and 126 questionnaires were collected and statistically analyzed. The main findings of the analysis are as follows. First, the centralization factor of organizational structure significantly affects the belongingness, responsibility, and devotion factors of loyalty. Second, the communication factor of organizational structure significantly affects the belongingness factor of loyalty, and it has a more substantial effect than centralization. Third, the moderating effect of library type on the effect of organizational structure on librarians' loyalty was found to be statistically insignificant. Based on the above results, this study suggests organizational structural measures to increase librarians' loyalty, and it is meaningful in that it is a study on an organizational field that has not been covered in depth in the literature.

This purpose of this study is to examine how emotional intelligence has a moderating effect on the relationship between emotional labor and job burnout. To test the hypotheses, moderation analysis, mediation analysis and moderated mediation analysis were performed. Of the 1,500 self-report questionnaires distributed to franchise employees, 1,412 usable responses and utilized in the final analyses. The resoults show that emotional labor significantly affected job burnout, and job burnout completely mediated the effect of emotional labor on turnover intention. And emotional intelligence moderated the relationship between emotional labor and job burnout, suggesting that the emotional dissonance-job burnout relationship was stronger in the low emotional intelligence group than in the high emotional intelligence group. The results of this study provide some implications for Korean companies entering the Chinese franchise field. First, the mediating effects of "emotional labor → job burnout → turnover intention" and the effect of emotional labor on job burnout were mitigated by self-efficacy in Chinese franchise workers. And the self-efficacy of the employees was an important factor. The implication of this study is that self-efficacy, which is a controlling variable affecting emotional labor, job burnout, and turnover intention, is important, so Korean companies that enter the Chinese franchise employ employees with high self-efficacy and to develop and implement an employee education program that can enhance self-efficacy.

Relationship with grandchildren mediates the effect of relationship with children on successful aging. In case of dismissing attachment style, the effect of relationship with spouse and grandchildren on successful aging were significant. Also the effect of relationship with children on relationship with grandchildren was significant. Relationship with grandchildren mediates the effect of relationship with children on successful aging. In case of fearful attachment style, the effect of relationship with spouse and grandchildren on successful aging were significant. Also the effect of relationship with spouse on relationship with children was significant and the effect of relationship with children on relationship with grandchildren was significant. Relationship with children mediates the effect of relationship with spouse on successful aging. This study explains the role of attachment styles as moderation variable of relationship with family on successful aging and also suggests the importance of marital and grandparents-grandchildren relationship as alternative supporter when the elderly has relational problems with adult children.

The study aims at verifying the effect of the image, trust and responsiveness to social welfare organizations on continuing the sponsorship of private donors, the mediating effect of the organizational identification and the moderating effect of their financial status. As a result of causal analysis of the variables by structural equation models, regardless of donors' financial status, social welfare organizations' image, trust and responsiveness has no direct effect on continuing the sponsorship. Among the donors in relatively good financial status, social welfare organizations' image, trust and responsiveness positively have direct effects on organizational identification, which has a direct effect on continuing the sponsorship. That is, the image, trust and responsiveness influence the continuity of the sponsorship through the full mediating effect of organizational identification. On the other hand, among relatively poor donors, only the organizations' image and trust positively influence the organizational identification, The direct and indirect effects on the continuity of the sponsorship are different according to the private donors' financial status, which means that the moderating effect of the donors' financial status is proved. The result of latent mean analysis regarding 5 main latent variables according to the private donors' financial status, shows the significant difference in the continuity of sponsorship only(Mean= .197, Cohen's D=.779). By emphasizing that Organizational identification is a critical factor in terms of enhancing the continuity of sponsorship, some practical implications are discussed based on the study's findings.

Large corporations have the work and roles of employees clearly defined in accordance with their established internal structure whereas small and mid-sized firms may lack an official job specification or a written job description, causing ambiguity in the role of employees. In IT service companies, especially, there is a relatively large number of tasks requiring one person to play multiple roles and they are often highly dependent on few key players. In this reality where about 80% of the job seekers end up in SMEs, it is therefore necessary to look into how the turnover factors such as job strain and occupational burnout caused by the role ambiguity from extra work affect the turnover intentions of small and medium sized IT service firm employees. The outcome of this study is as follows. First, the relationship between job strain and turnover intention has been examined to find that a weak inverted U shaped relationship exists between role overload, which is a subset of job strain, and turnover intention. Second, the hypothesis based on the competing values framework has been tested that the fitness with organizational leadership and culture would moderate the relationship between job strain and turnover intention and it has been confirmed that the degree of relationship between role conflict and role ambiguity, the subsets of job strain, and turnover intention has changed. In conclusion, in order to discourage turnover intention, it is necessary to increase the fitness with the organization and leadership or generate a sufficient level of strain in case of an organization with low fitness.
