Mobile messenger services (MMSs), such as Kakaotalk, Wetalk, Line, and Whatsapp, are gaining popularity worldwide because of communicating with other people without any cost. We examined key antecedents of user loyalty to understand user's decision-making process in the MMS environment. To capture a long-term relationship with service providers, we posit relational commitment and user satisfaction as key predictors of user loyalty. Moreover, the effects of perceived usefulness, perceived enjoyment, and corporate image on user's decision-making processes were examined. The proposed model was tested by applying partial least squares to data from 220 experienced Kakaotalk users. The findings of this study found that both relational commitment and user satisfaction play an important role in enhancing user loyalty in the MMS context. The analysis results indicate that corporate image influences relational commitment and user loyalty through user satisfaction. The analysis results help MMS providers establish management or marketing strategies to effectively improve user loyalty.

The communication via MIM(Mobile Instant Messenger) has unique characteristics; one of them is use of emoticons. Although using emoticons in MIM is getting a lot of attention from business fields and emoticons markets in MIM is growing rapidly, there are little researches focused on emoticons in MIM in consumer behaviors and marketing area. So, the purpose of this study is to fill this theoretical and practical gap. For this purpose, we explore the effect of and trust in MIM system and attitude toward use of emoticons on purchase intention to emotions in MIM. Our study used structural equation modeling analysis; the results showed that perceived benefits and perceived risk to MIM affected trust in MIM system significantly, more specifically, while perceived benefits affected trust in MIM system positively, perceived risk affected trust in MIM system negatively. We also found that perceived usefulness of emoticon in MIM and flow experience influenced attitude toward use of emoticons positively. Lastly, trust in MIM system and attitude toward use of emoticons had positive effect on purchase intention to emoticons in MIM. The implication and limitations of this study are also discussed.

최근 피싱과 파밍으로 인한 사용자들의 피해가 속출하고 있다. 또, OTP(One Time Password)의 MITM 공격에 대한 취약성이 밝혀지면서 기존의 인증기법을 개선할 필요가 있다. 그러므로 피싱과 파밍 공격을 방지하고 OTP의 취약점을 개선한 인증기법을 제안하는 것은 매우 중요한 문제이다. 본 논문에서는 메신저를 이용한 피싱/파밍 방지기능을 제안한다. 또한 제안하는 기법은 1차로 기존과 같은 ID / PWD 방식 인증과 2차로 모바일 메신저 상에서의 인증시작버튼, 3차로 물리적인 QR코드 인식 후 인증을 하는 3단계 인증을 통해 개선한다. 제안하는 인증기법은 일상생활 속에서 많이 사용하는 메신저와 카메라 기능을 통해 진행되므로 사용자는 추가적인 기능을 배울 필요가 없으며, 친숙하게 사용할 수 있다. 피싱/파밍 공격은 물론 MITM공격에 대한 취약점을 메신저의 특징과 2차, 3차 인증단계를 이용해 막아낼 수 있을 것으로 기대된다.

The aim of this study is to investigate the relationship between communication motive, fatigue and loneliness in mobile environment. According to previous research, the most important communication motive in mobile environment is pleasure. Therefore, pleasure was selected as a representative communication motive. To do this, we collected data for empirical analysis from mobile messenger users using questionnaire. We found that pleasure has a negative effect on loneliness. Second, pleasure has a negative effect on connection, function, and focus. On the other hand, pleasure has no effect on delivery and relationship fatigue. Finally, function and focus have a positive effect on loneliness. On the other hand, connection, delivery, and relationship fatigue have no effect on loneliness. As a result of the research, it is possible to reduce the function and focus fatigue due to the use of the mobile messenger by adding the functions that cause the enjoyment of using the messenger. In addition, the addition of fun-inducing features can also reduce loneliness caused by the use of mobile messenger. Future research will also need to identify factors that may reduce connection and relationship fatigue.
