This study is the first model to apply the concept of media engagement to a political campaign by which the voters' mind toward the supporting political candidates, are read. Thus it provides the theoretical and practical implications to the political campaign, and eventually contributes to the development of democracy. For these objectives, the total of 729 people who have the right to vote were telephone surveyed using the peoplemeter, CATI program in the 18th Presidential Election (12 areas including Seoul) of Dec. 19th 2012, and Re and By-election of April 24th 2013. Research question is to examine how the 5 attributes of the media engagement (interest, immersion, relevance, satisfaction and participation), play a role as the moderating variables in cross-correlation, socio-economic status and media properties. The result shows that of the five properties of media engagement, the relevant factor is the important parameter of mediating variable to the causal relationship. The media usage (TV, SNS, print media), socio-economic status (gender, age, income, marriage and area), involvement and the Presidential Election, and Re and By-election are also effective in the five attributes of media engagement. These results suggest that the a study model can measure the campaign effectiveness. This study will contribute significantly to the development of politics, election, media, advertising, and public relations area as well as to promote interdisciplinary research.

The purpose of this study is to explore the anti-smoking message effects and smoking status on smoking belief attributes. Based on the health behavior theories such as theory of reasoned action, health belief model, and social cognitive theory, three factors are selected to investigate the effects of anti-smoking campaign messages. The balance of benefits and barriers, self-efficacy, and social pressure are selected as independent variables. Three two-way ANOVA were conducted. Results showed that the main effect of social pressure were found with the social smoking attributes. Interaction effects were found on the nonsmoker-social pressure group and the non-smoker-two sided message group. It is found that nonsmokers accepted these two anti-smoking messages easily as compared to smoker groups. No main smoking status was found in this study; it is believed that smoking is a habitual that is not changed easily because attitude formation takes time. Results revealed that the two-sided message video releases and the social pressure video releases were favored by both smokers and nonsmokers. This study contributes the theoretical framework that can be transferred to the practices of anti-smoking campaign. Also, the researcher produced the televised stimuli which is not common in health message studies. By using the televised message material, the research tried to solve the validity problem which is common in experimental design.

This study empirically examines the differences in attitude and memory effect according to the product knowledge (high knowledge / low knowledge) and temporal distance (near future / far future) in the new product preannouncing strategy of companies through Facebook Respectively. Experiments were conducted by inserting the experiment into a virtual web browser using Facebook 's actual brand fan page and then connecting the experiment to the experimental banner site. As a result of research, when preannouncing new products are released in the near future, low knowledge consumers have made judgments of purchasing decisions because GRM judgments are more favorable than property information (ARM) judgments, but preannouncing is a new product At the time of launch, highly-knowledgeable consumers had a positive effect on the property information (ARM) judgment of the product rather than the comprehensive information (GRM) judgment. In addition, when preannouncing was introduced in the near future, the attitudes of the products between the low-knowledge consumers and the high-knowledge consumers were all positive, but when the new products were launched in the distant future, Product attitude was negative.

This quasi-experimental study examined the experience of simulation clothes and its effects among undergraduate nursing students. Method: The experimental group consisted of 44 sophomore students in a diploma nursing program, while 41 students comprised the comparison group. Only the experimental group experienced the functional decline of aging after taking on simulation clothes. Homogeneity between the groups was analyzed using t-test, and Fisher's exact test. Paired t-test and t-test were adopted for testing changes of attitudes and awareness of supporting elders. In addition, contents of students' reports of the aging simulation experience were analyzed. Results: No significant quantitative effect was observed in attitudes toward elders and awareness of supporting elders. However, the simulation experience seemed to have enhanced students' understanding of elders and of basic elder care as well. Furthermore, the students could think of preparing for their later lives. Conclusion: The experience of simulation clothes is a meaningful learning opportunity in gerontological nursing curriculum. Students' experiences need to be shared and reinforced in a discussion session. Safety should be secured in the process of the experience. The simulation experience can be further developed to raise its quality.
