초록

정보기술 발달은 다양한 기기에서 인터넷 망을 통한 음성통화를 가능하게 하고 있다. 스마트 폰에서는 무료로 제공되는 모바일 VoIP 앱을 설치하고 이용하는 사용자가 늘고 있다. 본 연구에서는 모바일 기기에서 확산되고 있는 무료통화 앱의 수용에 영향을 주는 요인을 밝히고 이들 요인간의 구조적인 관계를 파악하고자 한다. 이를 위해 관련 모바일 VoIP 관련 연구들을 살펴본 후 영향 요인들을 도출하고 이들 간의 구조적인 영향에 대한 연구모형을 설정하였다. 연구모형의 검증을 위해 설문조사와 통계적인 분석을 통한 실증분석을 실시하였다. 탐색적 요인분석을 통해 설문에 사용된 변수 사이의 요인을 찾아내었고 요인들 간의 구조적인 영향 관계를 규명하기 위해 구조방정식모형을 이용한 분석을 실시하였다. 실증분석 결과 모바일 VoIP가 제공하는 유용한 혜택과 사회적인 영향이 이용의도와 실제 이용에 많은 영향을 미치는 것으로 나타났으며, 이는 사용자를 대상으로 유용성을 강조하고 사회적인 영향을 강화할 수 있는 기능이 필요함을 시사하고 있다.

The progress of Information Technology enables people can communicate each others using the Internet. As a smartphone proliferates, many free mobile VoIP(Voice over IP) application are developed and accepted by smartphone users. In this study we investigate the factors affecting the acceptance of mobile VoIP applications and the structural relationship among these factors. We review the related works and extract the related factors and build a research model describing the causal relationship among these factors. We conduct an empirical study - a survey and statistical analysis - to verify the research model. EFA(Exploratory Factor Analysis) is applied for variables in the survey and SEM(Structural Equation Model) is used to reveal the structural relationship among the factors. We can find that two factors - usefulness of mobile VoIP and social influence - positively affect usage intention and actual use. These findings imply that it is required to emphasize the benefits of mobile VoIP use and add S/W functionalities enhancing social influence.
