김의곤(Eui Kon Kim),임일(Il Im) 한국경영학회 2015 經營學硏究 Vol.44 No.6

This research focuses on the media capabilities by comparing traditional media and mobile media. Previous studies have examined media capability and its impacts on communication performances. Media richness theory(MRT) and media synchronicity theory(MST) are representative framework in this area. However, little research has investigated communicators’ perception on media’s capability and synchronicity and how they affect communicators’ satisfaction and communication performance. This study argues that communicators’ perception about media, as well as actual capabilities of the media will affect communicators’ use of media and media’s effectiveness. The effectiveness of the media will also affect communicators’ satisfaction and group cohesiveness. An experiment was designed and conducted with a total of 313 college students and MBA students in South Korea and the U.S. Subjects were required to perform a group collaboration task using Twitter on either PC or mobile phone. Subjects worked on an experimental task in teams of four people. After experiment was completed, subjects were asked to answer a postexperimental questionnaire which was designed to measure subjects’ perceived media capability(transmission velocity, immediacy of feedback, parallelism, rehearsability, and reprocessability), satisfaction, and group cohesiveness. The results show that the type of media(PC and mobile device) does not significantly affect people’s perceived media capabilities. It implies that capability of a medium lies more on communicators’ perception and how they use the medium rather than physical attributes of the medium. It was found that the immediacy of feedback, parallelism, and reprocessability have positive influences on the communication satisfaction. The enhanced satisfaction also increases the group cohesion. This research empirically analyzed the key factors of media capabilities for communication satisfaction by verifying Media synchronicity theory in the group collaboration context.

최재원 한국무역연구원 2020 무역연구 Vol.16 No.5

Purpose This study attempts to predict the automobile sales volume and WoM Effect of electronic cars such as the Tesla Model S. Design/Methodology/Approach This study extracted the data in a new industry, specifically, an electronic car such as the Tesla Model S based on the literature review of the existing media theory: the Media Richness Theory (MRT) and the Media Synchronicity Theory (MST). The unstructured data was used as text data for classifying important topics following the flow of time. Using Latent Dirichlet Allocation (LDA) and Dynamic Topic Modeling (DTM), we deducted the significant topic related to the company performance such as sales volume. Findings We find out that the text mining approach allowed us to identify the derived indicators for an automobile manufacturer’s market success with centrality measures. Also, this research found evidence of conveyance and convergence for the communication process on the web relative to users’ web comments. Research Implications Although previous studies used the economic approach, this study established that social media could capitalize on using conveyance and convergence of the communication process (e.g., conveyance vs. convergence) based on MST through theoretical consideration.

최재원 한국무역연구원 2021 무역연구 Vol.17 No.2

This study identifies a big data analysis of online user comments from social media and describes product sales volume based on media richness theory (MRT) and media synchronicity theory. Design/Methodology/Approach This study utilized online user comments for electronic vehicles like the Nissan Leaf. The data was used as clustering various sales topics for developing market strategy. Using Word2Vec and Dynamic Topic Modeling, we developed important topics related to Nissan’s market performance with social network analysis. Findings We found online user responses affected vehicle sales performance with comments on social network sites. Also, dimensions for the communication process on social network services were different from user behaviors. Research Implications We found online user comments strongly affected automobile industry sales. Thus, firms should consider the power of social network services in the expansion of market volume with conveyance and convergence processes centered around big data in advertisements.

The Interaction Effects between Synchronous CMC Technology and Task Networks

Heedong Yang,Chulwoo Park,Min Soo Kim 한국산업정보학회 2008 한국산업정보학회 학술대회논문집 Vol.2008 No.10

A "task network" is a type of social network that consists of experts who exchange professional help and advice regarding executing tasks. In this study, we investigate the task network used within the IS department of a national bank in Korea. We identify how this network moderates the influence of computer-mediated communication (CMC) technology on an individual s task performance. Size, density, and centrality were measured as the characteristics of a personal task networks. Size equates to the total number of colleagues who work with a specific member for a certain project. Density is the ratio of the number of actual relationships to the total number of available relationships. Centrality defines whether an individual s position is in the exact center of whole network, and is measured by betweenness centrality, meaning the position one member holds between others in a network. Our findings conclude that the conditions - the larger the size of the task network, the smaller its density and the higher its level of centrality - lead to more benefits of using CMC media. Further, this positive effect of CMC is more noticeable when it provides synchronicity.

Based on the media synchronicity theory and literature about online communication, we identify the functional and emotional features of mobile messenger. In particular, this study demonstrates that functional and emotional features of mobile messenger would influence intimacy and fatigue. Also, intimacy and fatigue, as mediating variables, have an impact on user satisfaction and commitment toward mobile messenger service. The results of this study provide practical implications for mobile messenger providers and users which attempt to facilitate positive effect such as intimacy among users and reduce negative effect such as fatigue on mobile messenger communication.

The Impacts of Media Symbol Variety on Performance in Virtual Teams

심상민,서길수,임건신 한국데이터전략학회 2010 Journal of information technology applications & m Vol.17 No.3

The purpose of this study is to examine the impacts of media symbol variety on group performance in virtual teams. Symbol variety is defined as the number of ways in which information can be communicated and includes Daft and Lengel [1986]’s multiplicity of cues and language variety. According to media richness theory and media synchronicity theory, the use of media with high symbol variety is assumed to facilitate and promote communications among virtual team members. Therefore, it is expected that the media symbol variety is positively associated with group performance in virtual teams. Furthermore, online relationship building is expected to mediate the impacts of symbol variety on the performance. To confirm the suppositions, a controlled lab experiment was conducted with 60 undergraduate students as subjects. In the experimental virtual teams, subjects were allowed to communicate with other members using text-based messenger with emoticons. Subjects in the control virtual teams were allowed to communicate using only text-based messenger. The direct impact of symbol variety on group performance in virtual teams was found insignificant. However, the online relationship was found to completely mediate the positive impact of symbol variety on group performance. The implications and limitations of this study are also discussed for future research.

The Moderating Effect of Media Synchronicity in the Communication Media Use and Knowledge Creation

류성열,구철모 한국경영정보학회 2010 Asia Pacific Journal of Information Systems Vol.20 No.2

Social communications using information and communication technologies (ICT) for social interactions have been making a significant impact on task performance in organizations. However, most of the existing studies on ICT (e.g., telephone and email) have only focused on technical improvement of communication efficiencies (e.g., information exchange and storage). In this paper, we claim that ICT may be another alternative source of knowledge creation that enables employees to work, find solutions, and achieve their goals faster and better. We investigate the impact of ICT in terms of both tasks and social aspects with knowledge creation as task performance. Also, we investigate the moderating effect of media synchronicity on these relationships. This study contributes to the understanding of contemporary communications media usage and its performance in organizations. We collected and analyzed survey data of 248 company employees, using PLS. The results indicate that task urgency and social influence directly affect ICT usage, and even knowledge creation. Also the media synchronicity moderates the relationship between the characteristics of a given task and ICT usage and the relationship between ICT usage and knowledge creation. Theoretical and practical implications of these findings are also discussed in the paper.
