The Validity and Credibility of Crowdsourced Fact-checking
Demand of fact-checking has increased together with the amount of information. However, fact-checking is often neglected due to lack of time and labor source. Also, development of digital technology has contributed to the acceleration of information spread. As online information is overabundant, it is difficult for professional journalists to fact-check all information before publishing it. Many researchers are developing algorithms for fact-checking, but they are not practical yet. In order to assist those deficiencies of fact-checking algorithms, collective intelligence was considered as an alternative method. With the help from the public, journalists collect, classify, and analyze data, and also widen their perspectives.
This research aims to examine the validity of crowdsourced fact-checking and its credibility level compared to professional journalism fact-checking results. Lastly, the interface elements to enhance credibility of crowdsourced fact-checking results were observed. The results show that crowdsourced fact-checking process is promising except for ambiguous and partially true claims. The Mechanical Turk workers provided their deliberate opinions and critical evidence. Their rationale implies the possibility of public discussion and their capability of narrowing down broad statements to verifiable sentences. The credibility of traditional journalism fact-checking was generally higher than crowdsourced results but for certain categories crowdsourced condition had a higher credibility level due to the features of social media. Moreover, the reputation of the user was more influential to the credibility than social information disclosure level. The findings from current research implies the future design of fact-checking platform and how could the current fact-checking algorithms could benefit from the collective intelligence.
Emoticon Sticker Usage in Mobile Instant Message
As mobile instant messaging has become a major means of communication with the widespread use of smartphones, emoticons, symbols that are meant to indicate particular emotions in instant messages, have also developed into various forms. The primary purpose of this study is to classify the usage patterns of emoticons focusing on a particular variant known as “stickers” to observe individual and social characteristics of emoticon use and reinterpret the meaning of emoticons in instant messages. A qualitative approach with an in-depth semi-structured interview was used to uncover the motive in using emoticon stickers. The study suggests that besides using emoticon stickers for expressing emotions, users may have other motives: strategic and functional purposes.

Long-term Fandom and its Motivations for Married Women
An idol fandom is often considered as a teenage culture. A Korean idol group, ‘Shinhwa’, who debuted in 1998, has continued their album activities until now and most of its fans are in their late 20s or 30s. Usually, when an adult woman admires an idol star, people look at her pathetically, especially when she is married and has a baby. However, members of Shinhwa’s fan club, ‘Shinhwa Changjo (Creation of Myth)’, reveal themselves as fans of this idol group shamelessly. Although there are many limitations on their fan activities as married women, they consistently buy Shinhwa’s album and go to their concert.
Fans of Shinhwa were interviewed to investigate the motivations of their consistent fandom activities despite the constraints as married women. One’s identity is formed throughout lifetime, and teenagers start forming their identity by following an idol star as the object of admiration. This cannot last long because of the absence of the admirable object. Shinhwa, continued their activities for 18 years without change of its members. Their fans have affection for the group and not for the individual member, since they have ‘protected’ the group together. They also grant a special distinction to their group as well as themselves. For 18 years, the relationship between the star and the fans became strong and this ‘interdependent relationship’ differentiate themselves from other fandoms, providing the ground for them to reveal as idol fans.
Moreover, as their economic power grows, the fans can perform fan activities without their parents’ permission. A considerable amount of time and money is necessary for fan activities, but it is less burden to them compared to when they were students, and they can identify their social and economic position through these activities. Furthermore, the fans have shared social and cultural context for long time and this reinforces the relationship within themselves and also with the idol star. Through fan activities, they find themselves and liberate them from many activities which they gained through socialization.

Mobile Usage Research Using Scenarios with Vignette
As mobile usage increases, the more notifications from mobile message disrupt users. As a result, it is difficult to win users’ limited attention. To deliver the message more effectively to receive reply from receivers, many factors should be considered, i.e. interruptibility and message importance. To find out how those factors play in drawing appropriate attention, we examined how context of the receiver, sender and content of the message influence user action to the mobile message. Then, an appropriate notification style is investigated for particular scenarios. By using scenario-based method with simple vignettes, we found that the authority of the sender and message urgency affect the message importance. Also, users reply immediately when their interruptibility and message urgency is high and when the message contains less required action. Users prefer non-salient notification, but preferred auditory alarm to be turned on for urgent messages and from senders with high communication frequency.
