Many aspects of the way we work and live in the twenty-first century will be determined by the vast web of Internet. Virtual environments open the door to new identity experiences. Having the possibility to enter in a new community, where any personal information is directly shown to others, is a possibility to experiencing different self and thus to show and build new identities. This paper aims to identify how to relate the perception of cyber identity, loyalty and purchase intention. First, we classified cyber identity into two types, personal and social, and analyzed perception of each identity type. Then we conducted a survey using pre-designed questionnaire and found out factors consisting personal and social identity. Finally we analyzed the effects of these factors on loyalty and purchase intention using Structural Equation Model.

Existing loudness models are specified only to diotic sounds in spite of the fact that normal human beings hear dichotic sounds. Approximately, the arithmetic mean of loudness values of both ear signals has been suggested for the resultant perceived loudness. In this study, the dependence of overall loudness perception on the interaural level differences was investigated by the subjective tests. It was found that the larger the interaural level difference, the louder the perception than the mean of calculated loudness values at both ears and the lower the critical band rate or the reference level, the louder the perception than the mean value. A modified loudness model was proposed to he applicable to dichotic sounds by using the equivalent diotic levels.

This research was implemented by using TRAM model. An existing research (Ok 2011) which dealt with technology readiness and social commerce at once had only asked consumers' attitude on 'general technology'. This research, however, has specifically focused on Social Network Service and mobile social commerce. Research hypotheses and research model were developed and tested by using 610 consumer survey data. It was found that individual's positive/negative technology readiness has a direct influence positively/negatively on perceived ease of use and perceived trust respectively. Also their positive and negative technology readiness has an indirect influence positively/negatively on perceived usefulness. Thus someone's positive and negative attitude on SNS has a different direction towards the perception of mobile social commerce. Perception on mobile social commerce depends on their attitude (positive or negative) concerning SNS. Managerial implications and limitations of the study were also discussed.

Purpose: This study was done to identify levels of health teacher's perception and performance on abdominal pain management in elementary schools. Methods: The participants were 207 health teachers in elementary school in B metropolitan city. In a descriptive cross-sectional study, the structured self-report questionnaire was developed based on the literatures and school health care guidelines by the researchers. The data were analyzed using the PASW 18.0 program. Results: The mean scores (${\pm}SD$) on perception and performance of abdominal pain management were $4.02{\pm}0.43$ (range 1~5) and $3.47{\pm}0.41$ (range 1~5), respectively. Their perception and performance of abdominal pain management had a statistically significant correlation (r=.27, p<.001). In a regression analysis, the performance of abdominal pain management was significantly influenced by perception of abdominal pain management, career of health teachers, self-confidence in abdominal pain management, and total number of classes in a school. The regression model explained 19% of the variance of performance of abdominal pain management. Conclusion: These findings showed that the performance levels were lower than its perception levels of elementary school health teachers on abdominal pain management for students. It suggests that the standardized abdominal pain management guideline is developed to improve the performance of school health teachers.

Purpose: The purpose of this study was to investigate the contribution of actual cardiovascular disease (CVD) risk, as well as, individual, psychosocial, and work-related factors as predictors of CVD risk perception among Korean blue-collar workers. Methods: The participants were 238 Korean blue-collar workers who worked in small companies. Data were collected through a survey; anthropometric and blood pressure measures; and blood sampling for lipid levels. Results: Blue-collar workers had high actual CVD risk and low CVD risk perception. The significant predictors of risk perception included perceived health status, alcohol consumption, knowledge of CVD risk, actual CVD risk, decision latitude, and shift work. The model explained 26% of the variance in CVD risk perception. Conclusion: The result suggests when occupational health nurses are giving routine health examination in small companies, they can enhance CVD risk perception in blue-collar workers by providing essential information about CVD risk factors and personal counseling on the individual worker's CVD risk status.

Purpose: The purpose of this study is to analyze the relationship between characteristics of social media sites (SNS) and the intention of Pakistani tourists to visit South Korea while determining the role of usefulness, interestingness, and involvement of tourists. Research design, data and methodology: A research model was developed through the previous research, and the questioner-based survey was conducted on Pakistani tourists visiting Korea. The survey data was collected by following multiple hypotheses: the relationship between SNS tourism information and perception of SNS, the relationship between SNS perception and intention to visit, and adjustment of involvement in the relation between tourism information characteristics, and SNS perception. We used SPSS and AMOS24.0 statistical tools to analyze the hypothesis testing data. Results: Based on the data analysis, the study found that the characteristics of SNS have a positive effect on intention to visit via users' perception like usefulness and interestingness. The involvement has a moderating effect between SNS characteristics and users' perception. In the group with high involvement, the degree of influence of the quality factor of SNS on user perception was greater than in the group with low involvement. Conclusions: This study demonstrated that traveler's involvement has a moderating effect on the relationship between SNS characteristics and visit intention for Pakistani travelers visiting Korea. It shows that practitioners or researchers should establish and operate SNS strategies in consideration of user involvement.
