In this study, we examined the influence of news frame and involvement on risk perception. Based on individuals' optimistic bias in risk judgement and the third-person effect theory, we developed research hypotheses. An experiment was conducted in which 243 undergraduate and graduate students participated. Results indicated that societal level risk judgements were relatively invariant across experimental conditions but personal level risk judgements were influenced by the news frame and individuals' involvement in irradiated food. Based on the results, we provide explanations concerning when and how optimistic bias takes place in each experimental condition.

Recently, concern about family safety is rising again as an important issue with the context of family healthiness and well-being in Korean society despite of the dramatic economic growth. The purpose of this study is to examine the status of family safety of singles and single-parent households and to investigate the effect of social capital on the level of their family safety. Data are from the 10th wave of Korea Welfare Panel Study analysing one-person households(N=2,017) and single-parent households(N=172). One-person households were categorized as three groups by age(the youths/middle-aged/the elderly) and single-parent households were also three by family types(mother-child/fahter-child/grandparent-child). The major results were as follows: First, the mean of family safety index was highest among middle-aged, while single youths had the fewest problems in terms of family safety. Second, social capital was found to vary by family structure. In the one-person households, all the levels of the social capital variables, including trust, bond, acceptance, and participation, differed significantly; only two variables, bond and embracement, differed in the single-parent households. Third, social capital differed between the low-income households and others significantly. Forth, the positive effects of social capital on overcoming family safety problems were investigated. In conclusion, social capital represents an alternative resource for overcoming economic hardship for low-income one-person/single-parent households, especially for middle-aged singles and father-child single-parent households. Based on these empirical results, theoretical implications were discussed with regard to family policy and programs.

The speed and magnitude of mobile phone adoption is a recent worldwide phenomenon akin to those of the television in the middle of the 20th century and the Internet in the late 20th century. During the 2000s, mobile phone adoption was exploded and subscriptions reached 3 billion around the globe. Korea and Japan have been ahead of the rest of the world in introducing new handset and service capabilities. They were the first markets to launch 3G services and are currently the only markets to have achieved mainstream adoption of 3G with over one-third of customers in both markets subscribing to 3G services. The purpose of this article is to explore the cultural similarities and differences associated with mobile mail by presenting findings from a cross-cultural comparison of perceptions and uses of the technology. The results of the study are as follows：Of the characteristics that make up the mobile text-messaging service in Korea, a person's perceived ease of use and perceived enjoyment was found to have a positive effect on use attitude. Among the characteristics that make up a person's perceived ease of use, perceived enjoyment was found to have a positive effect on use intention. And use attitude was found to have positive effects on use intention. But, of the characteristics that make up the mobile text-messaging service in Japan, a person's perceived usefulness, perceived ease of use and perceived enjoyment were found to have a positive effect on use attitude. Among the characteristics that make up a person's perceived usefulness, perceived ease of use and perceived enjoyment were found to have a positive effect on use intention. And use attitude was found to have positive effects on use intention.

This paper aims to examine the third-person effect(TPE) of hate comments on online news, and analyze how the issue-relevant audience factors as well as the characteristics of the online message have influence on the TPE. More specifically, based on the distinction between hateful and logical comments regarding the issue of illegal immigration, the authors have conducted an online experiment that compares how the message-related features, i.e., ways of expressing the ideas, lead to the difference in TPE. Analysis was also conducted with regards to how political orientation and discriminatory predisposition to immigrants among the audiences, have different impacts on the TPE. The 479 participants in the experiments were randomly assigned to experimental group(exposed to hate comments) or control group(exposed to logical comments). The results reveal that the TPE of hate comments is higher than that of logical message. The same message proved to be more effective for news users with liberal orientation and discriminatory predisposition. The significance of this paper lies in that it has examined the effect of online hate comments in a rigorous experimental setting. Also the research further elaborated on the audience-related variables, for which the previous studies tended to focus those on the general psychological level rather than relate them more specifically to the issues.

The purpose of this study is to identify the relationship between PJF(person-job fit) and members' organizational commitment focusing on the mediating factor. Previous Studies have found that person-job fit has positive effect on organizational commitment, and self-efficacy has positive effect on the organizational commitment. On the other hand, the studies to identify whether self-efficacy has a role in mediation between PJF and the members' organizational commitment has been insufficient. To that end, we considered self-efficacy as the mediator of the relationship between PJF and organizational commitment. We used the data which to perform national policy research from 690 workers at a small or medium firm. As a result of verifying the suitability of the research model, it was suitable for the acceptance criteria. Besides the hierarchical regression analysis, bootstrapping was conducted to verify significance of mediating effect of self-efficacy. The main results are as follows. First, the variables, PJF, self-efficacy and organizational commitment showed a positive correlation. Second, PJF has a positive effect on self-efficacy and organizational commitment significantly. Also self-efficacy has a positive effect on organizational commitment significantly. Third, the mediating effect of self-efficacy in the relationship between PJF and organizational commitment is significant. In order to improve person-job fit, this study suggested that SMEs' owners should consider job rotation system and career development program for employees. Based on this study result and implications, we discussed limit of research and direction for future research.

Using structural equation modeling, this study sought to examine the structural causality between elderly age norms, social activities, and life satisfaction and to determine the moderating effect of death preparation activities. The analysis was conducted using data for 6,288 people over 65 years old, plus their spouses and children, taken from the '2017 National Survey of Older Koreans.' The study found, first, that the more positive the age norms to which the older person subscribes, the more their social activities increase. Second, as these social activities increase, the level of life satisfaction also increases. Third, the more positive the age norms to which the older person subscribes, the more the level of life satisfaction increases. Fourth, there is a significant positive mediating effect of social activity in the relationship between the age norms of the older person and life satisfaction. Fifth, there is a significant moderating effect of death preparation activities in the structural relationship between age norms, social activities, and life satisfaction that specifically impacts the age norm-life satisfaction relationship. Based on these results, practical plans to improve elderly people's life satisfaction are recommended.
