Redesigning Location-based Check-in App (Daum Place) and Its Interaction Flow

As the primary researcher on redesigning a location-based check-in app Daum Place, I conducted paper prototyping, formative usability testing, and semi-structured interviews to understand the use contexts and specific needs of users of Daum Place and other check-in apps (e.g., Foursquare, Facebook Check-in).

By triangulating the results from studies of different methods , this project identified the Daum Place redesign prototype’s UX problems and provided actionable insights to update the features, interaction flows, and content of this location-based check-in app.

Motherhood and Social Networking Sites: How do sociocultural contexts and technological factors affect Korean mothers’ KakaoStory use? 

In this project, I worked with Jinyoung Kim and Myeong Lee to examine Korean mothers’ use of mobile social networking service “KakaoStory.” Specifically, this project investigated the role of sociocultural contexts and technological characteristics that interact to shape Korean mothers’ use of this mobile-based social networking service. This study showed that the sociocultural context of Korean mothers as primary child caregivers interacted with the photo-driven user interface of KakaoStory to influence their specific use of KakaoStory for acquiring information and fulfilling their mothering duties.

Who was a neighbor to those from the other side of the globe?: International newcomer students’ local information behaviors in unfamiliar environments

This research (dissertation) examines international and domestic newcomer students’ information and technology practices and the role that their socio-national contexts play during their adjustment to unfamiliar host environments. Specifically, I developed a theoretical construct “local co-national context” through which I examined the varying information and technology practices of international students from around the world. I used a longitudinal mixed-method approach by conducting online surveys, follow-up semi-structured interviews, and cognitive mapping (a research method in which participants draw their own map of an area; see pictures below) over a two-year period.


Through this longitudinal, mixed method approach, I achieved a holistic characterization of the information behaviors of international newcomer students and identified the social and technological contexts that shape their varying information and technology practices during adjustment to host environments. My dissertation-based article has recently been published in Early View at the Journal of the Association for Information Science and Technology (JASIST).
