Kwahk, Kee-Young,Park, Do-Hyung Elsevier 2018 Computers in Human Behavior Vol.80 No.-

<P><B>Abstract</B></P> <P>The explosive growth of the internet as the main source of information and knowledge has greatly impacted the manner in which people make use of their memory. As a result, interest in the internet environment, and in particular in the role of transactive memory in a social media environment, has been heightened. Transactive memory is the shared memory system that is formed through interactions between people. Through social media, people have been able to form various human networks, which in turn have made it possible to acquire new information and knowledge. In this sense, the utility of transactive memory has been further increased in a social media environment. This study introduced social interaction, social presence, self-monitoring, and core self-evaluation as the factors impacting the formation of transactive memory capacity. The impacts of transactive memory capability on the tertius iungens orientation and individual job performance were also verified. Data from 225 workers was collected to verify the research model introduced in this study, which was empirically verified using a structural equation model. The study revealed that the four antecedent factors included in the research model significantly impacted individuals’ transactive memory capability and that the transactive memory capability positively influenced the tertius iungens orientation and job performance. Lastly, the results of the study were discussed, and the theoretical and practical implications were introduced.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The increased utilization of transactive memory in social media environment. </LI> <LI> The impact of individual and social factors on transactive memory capability. </LI> <LI> The relationship between transactive memory capability & tertius iungens orientation. </LI> <LI> The indirect effect of transactive memory capability on individual job performance. </LI> <LI> Theoretical and practical implications for social media management. </LI> </UL> </P>

The Effects of Use of Instant Messenger on Purchase Intention: The Context of Chinese C2C E-Commerce

Kwahk, Kee-Young,Ge, Xi,Lee, Jeong-Min The Korea Society of Management Information System 2012 Asia Pacific Journal of Information Systems Vol.22 No.2

In recent years, C2C e-commerce has become more and more popular in China. Chinese C2C buyers use an instant messaging more commonly during transactions compared to other countries, which seems to be an interesting phenomenon. Based on the Chinese market, this study aims to examine the role of instant messenger in the C2C e-commerce context and to find how it impacts buyers' purchase intentions. In addition to use of instant messenger, we brought in two antecedents of purchase intention-trust for vendor and customer satisfaction-to establish a theoretical research model. Through an online questionnaire survey, we tested and analyzed the research model and its related hypotheses. Structural equation modeling was used to analyze the data, and the results indicated that use of instant messenger did not directly influence purchase intention but had positive effects both on trust for vendor and customer satisfaction, which in turn influenced purchase intention. In conclusion, we discussed the research findings and suggested some implications for researchers and practitioners.

Understanding mandatory IS use behavior: How outcome expectations affect conative IS use

Kwahk, Kee-Young,Ahn, Hyunchul,Ryu, Young U. Elsevier 2018 INTERNATIONAL JOURNAL OF INFORMATION MANAGEMENT - Vol.38 No.1

<P><B>Abstract</B></P> <P>Implementing enterprise systems (ES) suffers from a high failure rate despite their promised benefits. A commonly cited reason for ES implementation failures in the context of mandatory use is end users’ unwillingness to adopt or use systems or their sabotage thereof. Considering that expectations toward using newly implemented systems may promote positive user behavior, we examine the effects of outcome expectations on information systems (IS) use activity from the viewpoint of social cognitive theory. In addition, we propose a new surrogate variable for IS use activity in the mandatory use context, conative IS use, which is conceptualized as a second-order aggregate construct comprising three dimensions: immersion, reinvention, and learning. Conative IS use here refers to IS use that is proactively motivated by intentional and personal causes. The empirical results, based on data collected from 208 ES users, are found to support the conceptualization of the proposed variable. They also reveal that conative IS use is positively affected by outcome expectations. The findings of this study thus imply that the appropriate management of expectations may promote IS use behavior in the mandatory use context.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Successful implementation of standardized enterprise information systems is often a challenging task. </LI> <LI> We examine the effects of outcome expectations on information systems use activity from the viewpoint of social cognitive theory. </LI> <LI> We propose a new surrogate variable, called “conative use” for system use activity in the mandatory use context. </LI> <LI> The empirical results reveal that conative use is positively affected by outcome expectations. </LI> <LI> The findings of the study imply that the appropriate management of expectations may promote enterprise system use behavior in the mandatory use context. </LI> </UL> </P>

The Impacts of Social Networks on Individual Adaptation to Technochanges

Kwahk, Kee-Young The Korea Society of Management Information System 2011 Asia Pacific Journal of Information Systems Vol.21 No.1

Despite the growing attention to the effective utilization of ICT system in workplace, there is an accumulation of evidence from the literature indicating that organizations do not utilize newly introduced ICT systems to their full functional potential and an amount of new implementations continue to fail. We explore the reasons for the underutilization of new ICT by focusing on the individuals' social networks. This paper investigates how the social networks influence individual adaptation to the new ICT and its related performance. Based on the coping theory, we establish a research model that explains the coping mechanism. Collected data are analyzed to test the proposed model and its hypotheses using PLS and UCINET. The results show that the coping effort mechanism of individuals can be explained in terms of their positions within social networks. We conclude the paper by discussing theoretical and practical implications for the research findings and by proposing future studies.

Human performance models using neural network

Kwahk, Ji-Young,Han, Sung-H. The Ergonomics Society of Korea 1996 大韓人間工學會誌 Vol.15 No.2

A single line display menu (SDM) is widely used for the user interface of many electronic consumer products, and the designers need useful guidelines applicable to the SDM. In many studies on menus, major focus has been placed on the optimal menu structure, but only a few standard menu structures, such as $64^{1},8^{2},4^{3}$,and $2^{6}$ are usually tested for optimality. In many cases, however, ill defined or asymmetric structures are suggested as design alternatives. To determine the optimal menu structure, user performance should be obtained in terms of quantitative measures. Hence, a model is needed to provide a predicted value of user performance for a given menu structure. Altough several models have been proposed for ordinary menus, none is available for the SDM yet. To solve this problem a performance model was developed in this study using the neural network approach. This model is capable of providing quantitative measures of human performance for any menu structures without conducting additional experiments, which will save much time and reduce the design cost.

A Simulation based Approach for Group Decision-Making Support

Kwahk, Kee-Young,Kim, Hee-Woong 한국경영과학회 2004 Management Science and Financial Engineering Vol.10 No.1

The changing structure of organization and the increasing diversity of business have forced organizations to have abilities to coordinate dispersed business activities. They have required cooperation and coordination among the functional units in the organization which should involve group decision-making processes. Although many group decision-making support tools and methods have been introduced to enable the collaborative process of group decision-making, they often lack the features supporting the dynamic complexity issue frequently occurring at group decision-making processes. This results in cognitive unfit between the group decision-making tasks and their supporting tools, bringing about mixed results in their effects on group decision-making. This study proposes system dynamics modeling as a group decision-making support tool to deal with the group decision-making tasks having properties of dynamic complexity in terms of cognitive fit theory.

An Approach to Support Group Works

Kwahk, Kee-Young 啓明大學校 産業經營硏究所 2003 經營經濟 Vol.36 No.1

The agility of an organization's response to the market demand has been recognized as one of critical factors in meeting competition. It has required cooperation and coordination among functional units in the organization which should involve group decision-making processes. Although many group decision-making support tools and methods have been introduced to deal with the group decision-making issues, there have been some limitations due to the following fundamental reasons - bounded rationality and dynamic complexity. To address these two issues, this study proposes system dynamics modeling as a problem-solving tool to deal with problem-solving tasks having properties of both bounded rationality and dynamic complexity in the group decision-making context.
