This study analyzed the factors that influence the domestic SMEs that have introduced smart factories on their intention to accept at a higher level for qualitative advancement. 375 copies collected through an online survey were analyzed using SPSS and AMOS with UTAUT and the extended two-stage information system continuous model. Performance expectancy, effort expectancy, social influence, and facilitating conditions have a statistically significant effect on user satisfaction and user satisfaction and CEO's will have an effect on the intention to accept the advancement. However, the suppliers' technology didn't have a direct effect on the advancement acceptance intention and user satisfaction has a mediating effect between performance expectancy, effort expectancy, social influence, facilitating conditions and the advancement acceptance intention. SME's advancement for smart factory, it is important to improve the satisfaction level and the CEO's will to become smart.

본 연구는 정보시스템이 조직에 수용된 후의 이용단계에서 사용자의 지속사용의도에 영향을 미치는 요인들간의 관계 모형을 도출하고, 실증하였다. 실증분석 결과, 성격심리유형과 주관적 지각인 기대일치, 자기주도성, 자기효능감이 정보시스템 수용 후 단계에서 지속적인 사용을 예측할 수 있는 변인으로 나타났다. 따라서 정보시스템 도입 초기의 기술수용관점에서 설명하였던 TAM과 그 확장모형들과는 달리, 수용 후 정보시스템 지속사용 성과 요인에 대한 인식을 사용자 중심으로 하는 방향으로 관점의 변화가 필요하다는 결론을 도출하였다.

정보화 사회에서 관광 웹 사이트는 그 지역의 가치가 있는 관광정보를 제공하고, 관광객을 유치하는 마케팅 도구로서 그 역할이 중요시되고 있다. 또한, 인터넷 정보 수용자는 관광 웹 사이트를 매개로 하여 그 지역에 대한 이미지를 갖게 되고, 점차적으로 일정한 태도를 형성하여 결국 관광지를 선택하는데 영향을 받는다고 볼 수 있다. 지방 자치 단체의 홈페이지에서 관광 홍보가 매우 중요하다. 그 이유는 첫째 인터넷 외에 지역의 관광정보를 여행하기 전에 입수하는 것이 매우 어려운 상황이고, 둘째로, 인터넷을 통한 관광 정보 탐색이 대중화되고 있기 때문이다. 정보탐색은 지속적 탐색이라 표현할 수 있는데 잠재적 관광객이 관광 홈페이지를 매개로 하여 그 지역의 대한 이미지를 갖게 되고 그에 따라 관광지 선택에 영향을 받는다고 볼 수 있다. 하지만, 광역자치단체의 웹사이트 상에서 관광정보를 구축하여 제공할 때에 정보 수용자 측면보다는 개발자 측면 중심으로 이루어진 경우가 많이 있다. 그래서, 막대한 재정적 투자를 통해 개발된 관광정보가 수용자의 욕구에 다소 못 미칠 수 있다. 이에 관광정보 수용자들의 정보탐색 요인을 파악하여 개발할 필요성이 대두되고 있다. 또한, 관광정보 요구자가 관광정보를 탐색할 때 그들의 특성에 따라 관광정보 웹 사이트를 평가하는 기준이 다르게 나타날 수 있다. 이를 기반으로 대학생들이 개인의 특성에 따라 웹 사이트의 평가에 미치는 영향에 대해 분석하고자 한다. 설문지법을 사용하여 전남 D대학교의 관광학 전공, 경영학 전공, IT(정보통신)학 전공 학생을 대상으로 총 90부를 설문조사 하였으며, 각 전공별 학생들을 컴퓨터 실습실에서 1시간 동안 전남도청 관광 웹 사이트를 탐색하게 한 후 설문지에 응답하는 방식을 사용했다. 개인의 특성에 따라서 관광정보 웹 사이트 수용도 에서는 유흥성향과 외향-내향성 성향이 관광정보 웹 사이트의 수용도에 영향을 미친다는 매우 유의하다는 결과를 도출 할 수 있었다. 웹 사이트의 특성에 따라서 관광정보 웹 사이트 수용도 에서는 탐색의 편리성, 정보의 충실성, 정보의 질이 관광정보 수용도 유의적이라는 결과를 도출했다. 하지만, 대고객 서비스에는 관광정보 웹 사이트 수용도에 대한 영향이 유의적이지 못한 결과를 보이고 있는데, 이를 위해서는 사용자에게 개별서비스 제공을 함으로서, 동영상이나 각종 사운드, 사용자 편의를 위한 관련정보 다운로드, 사용자를 고려한 부과서비스를 제공한다면 웹 사이트의 성과가 높을 것임을 기대할 수 있다.

This study aimed to demonstrate the effect of feedback type on users' subjective responses in a voice user interface. Feedback type is classified depend on information characteristic it involves; verification feedback and elaboration feedback. Error type is categorized as recognition error and performance error. Users' subjective assessment about system, feedback acceptance, and intention to use were measured as dependent variables. The results of experiment showed that feedback type has impacts on the subjective assessment(likeability, habitability, system response accuracy) of VUI, feedback acceptance, and intention to use. the results also demonstrated an interaction effect of feedback type and error type on the feedback acceptance. It leads to the conclusion that VUI should be designed with the elaboration feedback about error situation.

The purpose of this study is to define determinants of VoIP user acceptance and to verify significant causality among latent variables - performance expectancy, effort expectancy, cost expectancy, social influence, facilitating conditions, behavioral intend, use behavior - based on UTAUT model. We presented the expanded hypotheses including the new factor, cost expectancy and analyzed the moderating effect of user age, gender and usage experience variables. For a accuracy of predicted results, we focused on survey analysis with 641 real user samples. Compared to previous studies, it is meaningful that this research verified the conceptual difference between behavioral intention and usage behavior. As a result, all proposed hypotheses accepted and moderating effects are supported significantly in age and use experience moderating variables.

In this paper, we propose a methodology to estimate the number of users in e-Commerce systems. There have been a lot of previous work under the closed-LAN system environment. But the study on the number of acceptable users in real network environment is hard to find in the literature. Our research applies a Hybrid Simulation by using QoS results for end-to-end high-speed Internet service, and experiments are performed with regard to LAN and WAN, network equipments, and various network bandwidth. As result of the experiments we observed that the response time of high-speed Internet service media(Wireless LAN, ADSL, Cable, VDSL) depends heavily on the sequence and depth of transactions and on the ratio of transactional and non-transactional interactions. That is, as the network and application get more loads, the number of acceptable users decreases. By adding a cache server and an L4 switch to the simulation model, we analysed the changes in the number of users and client response time.

This study aimed to investigate the effects of user experience on Facebook acceptance behavior and advertising acceptance behavior. For the study, a survey was conducted among 367 male and female college students who use Facebook. In the results, first, functionality, usability, and pleasurable had positive effects on Facebook attitude, usability and pleasurable on flow, and reliability, usability, and pleasurable on the intent for continuous use. Second, functionality had a negative effect on advertising invasiveness while pleasurable had a positive effect on advertising attitude and no significant effect on advertising avoidance. The findings in this study provide basic data that can be used by various companies that use Facebook and advertising on Facebook for developing marketing strategy. In addition, future studies are expected on considering various variables related to user experience.

While the mobile application market is growing fast, the revenues of the majority apps are declining. Moreover, paid mobile application prices and purchases have been slow because of intensifying competition. However, the conventional studies focused only on the acceptance factor of mobile applications, so they cannot explain the phenomenon such as acceptance resistance for paid mobile applications. Therefore, our study tries to analyze the factors for the acceptance resistance of users for paid mobile applications. The research model in this paper, which is based on S-O-R model, verified through surveys how social influence and app characteristics affect user perception and how user perception affects to app resistance. The results of our study showed that paid mobile applications happened to be destroyed in front of the chasm because of the perceived loss. Consequently, the results implicate that the developers should lower the initial price and actively react to the negative reviews in order to lower the perceived loss. Moreover, the results verified that a sense of self-efficacy can lower application acceptance resistance by including personal properties to our research model as control variables.
