With the recent revitalization of the shared economy, bike-sharing services are gaining huge popularity in the bicycle sector. Bike-sharing services are characterized by reducing environmental pollution and borrowing bicycles at low prices. This study investigated the mechanisms for the formation of customer's continuance intention toward bike-sharing services. The theoretical framework clarified the role of perceived value and trust in enhancing customer's continuance intention. Perceived usefulness, perceived ease of use and perceived enjoyment are considered as the vital factors of enhancing perceived value and trust in a service provider. The research model was validated by data from 217 bike-sharing users in China. Both perceived value and trust in a service provider had a significant impact on user's continuance intention. However, the analysis results showed that perceived usefulness does not have a significant impact on both perceived value and trust in a service provider. Perceived ease of use and perceived enjoyment played a significant role in enhancing both perceived value and trust in a service provider. Our results are expected to provide academic and practical implications for bike-sharing services.

This study investigated the key factors affecting online relational intimacy in the context of SNS. Based on the use and gratification theory, self-presentation, relationship formation and information searching were identified as the main needs of SNS usage. These needs were expected to influence online relational intimacy through user satisfaction, subjective well-being, and disclosing information behaviors. The theoretical framework was validated by a longitudinal method. Hypotheses were tested by using the partial least squares to data from 199 Facebook users. Self-presentation and information searching had a significant impact on both user satisfaction and subjective well-being. However, relationship formation did not significantly affect both user satisfaction and subjective well-being. User satisfaction had a significant direct effect only on online relational intimacy. Subjective well-beings played a significant role in enhancing both disclosing information behaviors and online relational intimacy. Finally, it has been found that disclosing information behaviors are a key factor in enhancing online relational intimacy. The results of this study are expected to provide academic and practical implications for the key antecedents of online relational intimacy.

The findings of ferromagnetic superconductor have attracted much attention not only for fundamental research to investigate how the antagonistic properties of ferromagnetism and superconductivity coexist peacefully but also for potential technological applications. Firstly, in order to help for understanding the ferromagnetic superconductor, I have explained the orbital and paramagnetic pair-breaking effects of magnetic field, which breaks the superconducting Cooper pairs. In addition to such effects of magnetic field, the singlet Cooper pairs become unstable upon going through the ferromagnetic materials by the proximity effect. The proximity effect occurs at the interface of thin films composing of superconductor and ferromagnet and leads to have very short penetration depth of Cooper pairs. However, a type of odd-frequency triplet in comparison with the singlet could be very stable and has a longer effective depth. It needs to be explored for the innovative spintronic devices. Finally, various ferromagnetic superconductors coexist and the lower-dimensional materials under the Quantum confinement effect have been introduced.

Consumers possess their own psychological distance towards products. Based on the construal-level theory, this study aims to analyze which type of advertising appeal is more effective according to psychological distance. Also this study conducts neurophysiology experiment through eye-tracker. By using eye-tracking methods, participants' responses to products was measured and analyzed accordingly. Results revealed that consumers prefer rational appeals when the psychological distance is perceived near, while emotional appeals are preferred when the psychological distance is perceived far. In addition, eye movements measured in Visit Count(VC), Fixation Count(FC), and Total Fixation Duration(TFD) showed significant difference when participants are viewing preferred and non-preferred appeals.

Product image location in search engine advertising plays an important role in consumer perception when the product is relatively low involved and has functional value. The purpose of this research is to investigate the interaction effects of product image location and product type on advertising effectiveness. Building on the literature of location effects, we show that for products for which heaviness is considered a positive attribute, product image placed on the right are preferred. To test hypotheses, a 2(product image location: left vs. right) × 2(product type: single vs. bundle) experiment is conducted and a total of 144 paricipants took part in the experiment. The results revealed that respondents show higher brand attitude and purchse intention toward a bundle product's advertising with product image place on the right. The results provide implications and suggestions for improving search engine advertising and marketing strategies.

The purpose of this study is to investigate the effects of the actual self congruity and the ideal self congruity on positive attitudes toward city through fictitious city brand experiments. Additionally, the moderating role of city brand personality in relationship between brand-self congruity and positive attitudes are examined. This research conducted a survey after developing scenarios of two city brand personality. Frequency analysis to identify the characteristics of respondents, t-test to check the experimental manipulation, multiple regression analysis and chow test for hypothesis testing were performed through the SPSS Statistics 21 program. The self congruity of city brand had significant effects on attitudes toward city, but the moderating role of city brand personality was not significant. Theoretical and managerial implications of the findings were discussed and self congruity is an important variable in brand-consumer relationship in city brand. Finally, limitations of this study and future research directions were discussed.

It is very important to have pre-service teachers enhance actual content development skill for STEAM classes through deep understanding of the concept. Thus the purpose of the study is to explore the educational methodology for improving pre-service teachers' competence of designing STEAM classes. The research performed with 17 pre-service teachers from Y university and 15 from S university in 2015. It includes blended learning methodology mixing online and offline classes. The result revealed that the students' perception on and the materialization skill of the STEAM education was improved by the methods of Lesson Study and blended learning. A positive result also came out in the respect of the perception on teaching with technology.

Current research examined the effect of fit in the executional cue on brand memory for luxury and non-luxury brand advertising. In particular, this research looked at music to see how well individuals memorize information about brands where background music and sound logo fit or non-fit in the advertisement. As results, the influence of fit in music was higher in the luxury brand advertisement than that of non-luxury brand. The findings demonstrate fit leads more positive response not only in the relationship between the executional cue and the brand image or executional cues, as seen in the literature, but also in the executional cue. Moreover, the effect of fit in the executional cue is greater for the luxury (vs. non-luxury) brand. Based on the results, present research proposes the academic and practical implications.

The mobile payment service, which shows remarkable growth, appears to have different situations between Korea and China. Based on the recent research, we tried to confirm that there is a difference in the technology readiness index of third-party mobile payment service between Korea and China. The data were collected from a survey of Korean and Chinese university students. As a method of analysis, t-test was conducted for each factor. The results show that there is a difference between China and Korea in all factors of technology readiness. In particular, Chinese users' optimism, innovation and discomfort were higher and insecurity was higher in Korean users. These results are expected to provide a strategic approach to expand the use of third-party mobile payment services.
