The purpose of this study is to investigate the influence of service quality factors and related ties on the repurchase intention of home shopping products and application home shopping through smart media using relation bonding according to the platform. In this study, it was confirmed that the relationship between home shopping and home shopping follows the process of establishing brand equity by mediating or partially mediating the influence relationship between specific service quality factor and repurchase intention. At this time, the mediating effect of the relationship tying is different according to the home shopping platform, but the relation of the TV + application group to the use of TV home shopping has no mediating effect. Also, according to users' usual media usage habits, service quality factors for home shopping have different influence relations on repurchase intention through relationship binding.

Study on the instability of waste plastic's thermal pyrolysis oil was carried out for the purpose of improving its quality. The reaction of pyrolysis oil with ozone changed double bonds into aldehydes and ketone, estimated that HDPE pyrolysis oil contained $\sim45$ wt% 1-alkene type olefins, and PP pyrolysis oil did $\sim73$ wt% olefins, which consisted of $\sim47$ wt% secondary and $\sim20$ wt% primary alkenes. The dark brown color and odor of pyrolysis oil were improved by eliminating double bonds, indicated that they were directly related to unsaturated hydrocarbons. Container test showed that metal can affected oil quality worse than the brown glass bottle. Antioxidant added into pyrolysis oil was consumed up to 90% within $2\sim3$ days and the wt. composition of unsaturated hydrocarbons in pyrolysis oil was not changed within 50 days, inferring that instability of pyrolysis oil due to unsaturated bonds can be stabilized by antioxidants. Adsorption test on silica gel, activated carbon and alumina to remove precipitates in oil produced a good result, but not enough to remove moisture. However, cheap anhydrous sodium carbonate showed the best removal efficiency of moisture as well as precipitates in oil. Therefore the pyrolysis oil quality improvement was accomplished by applying anhydrous $Na_2CO_3$ into the production plant.

The happiness of social worker's role in promoting the happiness of the people has been relatively overlooked. Despite the importance of the ultimate value and meaning of eudaimonic happiness felt by social workers as a value-oriented profession, negative aspects such as work-related burn-out or hedonic happiness such as pleasure has been mainly focused so far. Happiness is a concept that must be met with both hedonia and eudaimonia, and it is necessary to understand both two dimensions of job satisfaction experienced by social workers. The purpose of this study is to investigate 376 social worker's hedonic and eudaimonic job satisfaction and factors associated with them by analyzing "Social Worker's Eudaimonia" dataset in which the Korean Version of Global Hedonic & Eudaimonic Job Satisfaction(K-GHEJS) scale was used. The results showed that the factors affecting hedonia and eudaimonia were different so that hedonia was statistically significantly associated with the levels of education, income and workload while eudaimonia was not. Based on these results, how to improve the hedonic and eudaimonic job satisfaction among social workers was discussed.

The purpose of this study is to analyze the moderating effect of health privacy information on the relationship between the factors that affect the behavioral intention of the usage of u-health system have. Therefore, as a research hypothesis in TRA (Theory of Reasoned Action), self-efficacy and perceived usefulness will have a positive effect on the behavioral intention of the u-health system, and in the path, that personal information factors have an effect on each path. This study used the PLS-SEM methodology to verify the proposed research model. As a result of the analysis, this study showed that the moderating effect of health personal information in the presented model affects to some extent by the increase of R2 explanatory power. However, it was found that it was more consistent with the role of the independent variable rather than the moderating influence on the perceived usefulness.

In MMORPG (Massively Multiplayer Online Role-Playing Game), users advance their own characters to get to the maximum (max) level by performing given tasks in the game scenario. Although it is crucial to retain users with high levels for running online games successfully, little efforts have been paid to investigate them. In this study, by analyzing approximately 60 million in-game logs of over 50,000 users, we aimed to investigate the process through which users achieve the max level and churn of such users since the moment of achieving the max level, and determine possible indicators related to churn after the max level. Based on the result, we can predict churn of the max level users by employing behavioral patterns before the max level. Moreover, we found users who are socially active and communicate with many people before the max level are less likely to leave the service (p<0.05). This study supports that communication patterns are important factors for persistent usage of the users who achieve the max level, which has practical implications to guide elite users on enjoying online games in the long run.

The present study analyzed the effector that has an influence on continuance intention to use YouTube that is a prime platform to distribute visual contents. Whether the dispersion of information communication technology succeeds or not is determined by a more extent which user uses active and continued than adopts fast. From this point of view, we employed partial least square(PLS) path modeling to analyze structural causality among constructs in the post-adoption model(PAM). As a result, all paths given in PAM except for the path 'confirmation-satisfaction' were validated. Especially, confirmation mediated with satisfaction than perceived usefulness has a more effect on continuance intention. Finally, we described the limitation of the present study and the suggestion for future research.
