Since smartphones have become the main communication tool for modern people, mobile messenger services are now an important part of daily activities. Why do the majority of people choose to communicate with others through mobile messengers rather than phone calls?


At the 16th International Conference on Electronic Business (ICEB 2016), the presentation of Yonsei University Barun ICT Research Center researchers Yong Wan Park and Ae Ri Lee was on how media and behavioral characteristics of mobile instant messenger affect intimacy and fatigue,
focusing on the moderating effect of the context of communication. In their study, the characteristics of mobile messengers, such as feedback, parallelism,
system of symbols, possibility of trials, and the ability to repeat processes were proposed as reasons for the use of a mobile messenger. Communication connectivity and consideration of others are identified as characteristics of user behavior. The influence of these characteristics on the closeness and weariness experienced by mobile Messenger users were examined.


Research results showed that when people did not receive quick replies from friends and their messages on mobile messengers were left unread, they are concerned with weariness. In contrast, a continuous feeling of being connected through mobile messenger enhanced their sense of closeness. In particular, there were differences in research outcomes on the degree of messenger
use. People were more considerate when using mobile messengers in their work lives compared with their personal matters. Moreover, people felt greater communication connectivity when they used mobile messenger for personal purposes rather than for work, and were more greatly exhausted by receiving immediate replies on mobile messenger when it was for work. Therefore, the influence of each variable was different depending on the context for using mobile Messenger.


The ICEB 2016 was hosted by the Department of Business Administration at Xiamen University and sponsored by the International Consortium for Electronic Business in Xiamen, China from December 4 to 8, 2016. The theme of the conference was “Internet Plus,” referring to the utilization of internet and information technology as industries converge. E-business researchers worldwide gathered to share their findings from their recent studies and exchange ideas.
