Purpose This study discusses the contradictory behavior of smart-phone users who consider security is important, but they do not follow the security recommendations. We found through literature research that this contradictory behavior is resulted from a low level of efficacy. Design/methodology/approach Research hypotheses were set based on Extended Parallel Process Model, Control Theory, and Self Efficacy Mechanism. The data were collected from undergraduate students. Total of 178 data were used for the analysis. Findings Results of the analysis, first, showed that the relationship between threat and security attitude varies with the level of coping efficacy. Second, showed that the relationship between threat and fear does not vary with the level of coping efficacy. Both the groups with high coping efficacy and low coping efficacy had a statistically significant effect on the relationship between threat and fear.

Purpose Social Network Service (SNS) users feel fatigue in process of using open type of SNS like Facebook and Twitter. Compared to the open SNS, the closed SNS takes an closed form to prevent privacy exposure, and they are more practical and advantageous to form deeper social relationships. This study attempt to examine the effects of the mobile closed SNS characteristics (such as usefulness, playfulness, perceived security, psychological privacy, social influence, and belonging) on the users' continuous SNS usage intention. Design/methodology/approach This study used a mixed methodology combining in-depth interviews and empirical validation to investigate the effects of the mobile closed SNS characteristics on the continuous SNS usage intention of users. Findings Analytical results from a survey of 210 mobile closed SNS users showed that except perceived security, the effects of the five SNS characteristics on continuous SNS usage intention were significant. These findings contribute to improving the quality of mobile closed SNS services and suggesting SNS related marketing strategies.

Purpose By participating in the business ecosystems, customers make both positive and negative impacts in the ecosystem. In particular, users of platform businesses participate in the business ecosystem as partial employees who voluntarily create and manage content. According to the organizational behavior literature, employees' psychological ownership toward the organization has an influence on the organizational competitiveness. Thus, with an assumption that customers gain psychological ownership toward the business that they participate in, it is important to analyze the process and the factors that influence their psychological ownership. This study proposes a research model that describes the process: customers undertake customer socialization, which then lead them to participate in the business-level and the business ecosystem-level activities. Through the participation, customers gain psychological ownership toward the business. Design/methodology/approach Based on a structural equation model, this study analyzes the data regarding the factors in the research model. Data was collected by surveying college students who represent themselves as Facebook and DaumKakao users. By analyzing the collected data, the relationships are validated between customer socialization and customer participations (i.e., both business-level and business ecosystem-level participation), and between the participations and customers' psychological ownership. Findings Based on the validation, this study confirms the importance of managing customers' psychological ownership and offers customers' participation by their socialization as a solution for increasing customers' psychological ownership. Also, this study proposes the business ecosystem research model as the general research framework for future research and expands the scope of strategic management from the individual level strategy to the business ecosystem wide perspective.

Purpose While new versions of mobile applications could offer users better computing environment, users are not always comfortable with them for various reasons. Considering making update decisions is important task for users, it is crucial for us to understand users' behavior and attitude on app updates. The purpose of this study is to explain why mobile users succumb to both reactance toward the update and satisfaction to the current version, ultimately leading them to feel the regret by employing three theoretical perspectives including regret theory, status quo bias theory and the dual model. Design/methodology/approach Survey data collected from 204 mobile users was used to test the research model using partial least squares analysis. The results have shown that both reactance toward the update and satisfaction to the current version have negative impacts on individuals' decisions to update, which leading to their regret after updating the applications Findings By integrating both status quo bias and regret theory in the model, this study tried to explain why mobile users feel regret in application update settings. More specifically, this study has proposed a novel framework that introduces an individual's update decision on mobile applications.

Purpose: This study was tried to investigate a structural relationship among key impacting factors and usage in SNS of government institutions. It was designed to research the processing property of SNS, the emotional property of SNS, and the service property of SNS for the SNS usage. Based on the research framework from the relationships among intrinsic SNS characteristics, social psychological characteristics, and the attitude of government institutions' SNS, the empirical research model and the hypotheses were established. Design/methodology/approach: Data for empirical study were collected from 453 of total distributed 500 by the structured questionnaire survey with SNS users of government institutions. The analysis was performed from effective 432 data, and the sample was mainly consisted of men, the thirty-old, and salesmen. Findings: The results showed that the emotional and service properties in intrinsic characteristics of SNS have a significantly positive effect to the value perception and the security variable in social psychological characteristics has a significant positive effects to the trust. Finally, the value perception has positive effects on both trust and use intention of government institutions' SNS. Meaning of these results is that intrinsic SNS characteristics, social psychological characteristics, and the attitude of government institutions' SNS have a significant effect on SNS usage.

Purpose The purpose of this study is to introduce U-CAAM(University-Competence Assessment & Accreditation Management) system which is designed to effectively manage extracurricular education programs in a university. Extracurricular education is known to be very important to increase core competences of students who have different levels of knowledge and skills as well as career plans. Design/methodology/approach In this study, U-CAAM system which is designed and developed to tackle the problems related to university extracurricular education is introduced. The case will give meaningful insights to those universities which consider to have similar environment. The survey is conducted to show the need to a systematic management environment to effectively manage the problems with operating extracurricular education programs. Findings The survey result shows that universities understand the need to manage extracurricular education programs effectively. Implementation of U-CAAM provides the practical insights related to this issue.

연구목적 컴퓨터 기반의 아이디어 생산 그룹들이 그렇지 않은 그룹들에 비해 여러 면에서 월등한 퍼포먼스를 보여 왔다고 컴퓨터 기반 브레인스토밍 연구들은 주장한다. 하지만 다른 연구들은 컴퓨터 기반 아이디어 생산 중에 발생하는 인지자극 시너지가 노미널 그룹과 비교했을 때 예상치보다 크지 않다고 지적한다. 컴퓨터 환경 하에서는 개인의 성향 차이에 따라 긍정적이고 부정적인 영향력이 다르게 작용한다. 따라서 본 연구는 아이디어가 생산될 때 발생하는 타임 스탬프를 분석하여 개인의 성향 차이가 아이디어 생산과정에서 어떤 영향을 미치는지를 관찰한다. 방법론 외향성/내향성 개인차와 아이디어 자극수위 (0/20/40/80개 아이디어)를 결합한 이원요인계획법을 사용하였다. 각 실험참가자는 무작위로 8개의 실험조건 중 하나에 할당되었다. 그룹시뮬레이터를 이용하여 실험참가자들의 퍼포먼스를 관찰하였다. 데이터베이스에 모아진 아이디어들 가운데 중복되지 않은 아이디어와 각 아이디어의 타임 스템프를 분석에 사용하였다. 결과 실험결과 (1) 내향성 집단은 외향성 집단에 비해 아이디어 세션 중반부 이후 생산성이 현저히 떨어지는 양상을 보인다. (2) 내향성 집단은 외향성 집단에 비해 현저히 적은 범주의 아이디어 생산 양상을 보인다. 따라서 컴퓨터 기반 브레인스토밍은 외향성 집단의 생산성 향상에 더 적합한 방법으로 보여진다.

While information technology(IT) users' behaviors has been considered one of the most important research topics and studied in very many ways, 'non-use' has not been focused as a research topic. However, understanding non-use provides new insights for analyzing and understanding the essential nature of IT uses with wider frames and more qualitative dimension. The objective of this study is to provide some guidelines for studying non-use. For this purpose, the previous studies for non-use were reviewed focusing on resistance, suggested potential research issues and some research methodologies based on grounded theory.
