The present study examined the factors influencing individuals' risk information seeking and processing using the case of 2015 MERS outbreak in Korea. Analyses of two-wave online panel data demonstrated that perceived risk, negative affect, subjective norm, and information insufficiency predicted the risk information seeking/avoiding as well as information processing mode, which validates the Risk Information Seeking and Processing(RISP) model. More importantly, this study found new evidence that information seeking and systematic processing promoted MERS preventive behaviors. In addition, active SNS use moderated the link between perceived risk and negative affects about MERS crisis as well as the relationship between social normative pressure and to seek the risk related information.

Image distortions are typically characterized by degradations of structures. Dictionaries learned from natural images can capture the underlying structures in images, which are important for image quality assessment (IQA). This paper presents a general-purpose no-reference image quality metric using a GRadient-Induced Dictionary (GRID). A dictionary is first constructed based on gradients of natural images using K-means clustering. Then image features are extracted using the dictionary based on Euclidean-norm coding and max-pooling. A distortion classification model and several distortion-specific quality regression models are trained using the support vector machine (SVM) by combining image features with distortion types and subjective scores, respectively. To evaluate the quality of a test image, the distortion classification model is used to determine the probabilities that the image belongs to different kinds of distortions, while the regression models are used to predict the corresponding distortion-specific quality scores. Finally, an overall quality score is computed as the probability-weighted distortion-specific quality scores. The proposed metric can evaluate image quality accurately and efficiently using a small dictionary. The performance of the proposed method is verified on public image quality databases. Experimental results demonstrate that the proposed metric can generate quality scores highly consistent with human perception, and it outperforms the state-of-the-arts.

We aimed at identifying the determinants of favorable UCC usage and creation by integrating emotional dimension, social influence and motivations. The finding show the significant effect of pleasure on intrinsic motivation in both Korea and U.S.A. Arousal has a positive effect on intrinsic motivation in the United States, but it has no relationship wit h intrinsic motivation in Korea. In case of social influence, subjective norm gives a significant impact on extrinsic motivation whereas proved insignificant in the United States. Image is shown to be significantly related with extrinsic motivation in both nations. Also, intrinsic motivation does not posit an effect on UCC usage and creation in Korea whereas it influences on UCC usage and is not related with UCC creation in the United States. In addition, it was observed that UCC usage has a positive and significant impact on UCC creation in both nations.

The foods served in festivals only affect attractiveness on visitors in itself. Because residents, tourists and vendor flow into the site in opening periods. In this case, there are always the possibility to happen to accident in site unprecedently. Therefore, The purpose of the study is to examine how visitors perceive the foods vendors served in festivals and how the factors influence among the casual relationship to applying the planned behavior theory. The Results is following up. Behavior Intention is affected the variables of belief, subjective norm and perceived behavior control. Final varialbe Food buying is affected the variable of behavior intention positive, but perceived behavior contro is not significant(p<0.05). Festivals make for the depar from the life, the attractiveness of the food happen to buy it stronger than the control ability of visitors. The health control for the food is needed systemically on the focus of the risk management

In this study, the selection attributes of contemporary dance audience were constructed based on prior study and the selection attributes of contemporary dance performance were identified through EFA(Exploratory Factor Analysis). Therefore, Six attributes were derived: physical evidence, tickets, people, information, product, and reputation. Based on these attributes, the selected attributes were identified through 'ETPB(Extended Theory of Planned Behavior)' to see if they affect ticket purchase behavior. In result, Among the selection attributes of contemporary dance performances, three attributes of reputation, people and product influenced the audience's attitude, while only product and human attributes influenced the purchase intention of tickets. Among the variables of ETPB to enhance the ability to purchase intention of tickets, audience attitude, perceive behavior control, and prior knowledge have had a positive effect on purchase intention of tickets, except for subjective norm. Therefore, it is meaningful that this study presented and verified empirically the attributes of select centered on visitors, which can improve the intention of purchasing tickets for contemporary dance performances.

Objectives: This study was to develop a measurement scale that explains aggressive regulation behavior of middle school student, based on Ajzen's Theory of Planned Behavior (TPB) and verify its validity and reliability. Methods: The basic items were modified by selecting 41 items of middle school student aggressive behavior measurement scale. Through the content validity test, 63 first preliminary question items and 42 second preliminary question items were developed. The participants were 286 middle school students. The collected data were analyzed using content validity, correlation coefficient, exploratory factor analysis, confirmatory factor analysis, reliability and Cronbach α. Results: In this study, it was proved that the most important variable showing aggressive regulation behavior was aggressive regulation intention. This study was composed of 4 factors for direct measurement(attitude toward the behavior, subjective norm, perceived behavioral control, behavior intention) and 5 factors for indirect measurement(behavioral beliefs, outcome evaluation, normative beliefs, motivation to comply, control beliefs). The total variance was 65.4% and 67.6%, respectively, and the reliability was .90, .82. Finally, 42 questions were developed. Conclusion: We found the questionnaire used in this study was valid and reliable as a measure scale to explain the aggressive regulation behavior of middle school student based on TPB. Therefore, it is concluded that the aggressive regulation behavior scale could be a useful scale for the measurement of the aggressive regulation behavior of middle school student.

This research attempted to identify the factors associated with the intention of human papilloma virus vaccination among mothers of elementary school daughters. The subject of study is 132 mothers of elementary school students. Data collection was conducted from July 1 to August 30 in 2017, and analyzed using SPSS 23.0 Program. Results showed that 94.7% children of the participants had not been vaccinated, whose reasons were the low knowledge about HPV vaccination, concerns about its side effects, burden for cost. The attitude toward HPV vaccination appeared to be the most important predictor of vaccination, which was followed by perceived behavior control and subjective norm as meaningful predictors, as well. Based on these results, further researches should be conducted to develop educational programs, which are able to offer exact information about the effect and side effect of HPV vaccination, and verify the effectiveness.
