The purpose of this research is to investigate the effects of brand extension on original brand in mobile market. TAM (Technology Acceptance Model) was used in current research to verify the 'intention to use of mobile service', and 'perceived usefulness', 'perceived ease of use', and the effect of 'extended brand's intention to use' on continuous 'intention to use in original brand' are verified in the process. According to the results, TAM was found to be appropriate to verify the intention to use of mobile service. Also by verifying the effect of decision factor, it is found that perceived ease of use have positive(+) influence on continuous intention to use of original brand. According th this finding, marketers will be able to understand better in performing strategies in mobile service environment.

근래 지구온난화에 따른 자연재해의 증가와 장기 코로나19의 전염으로 사회적 비대면 필요성이 증대되면서 온라인을 통한 건강관리 및 의료 진단·처방 등 디지털 헬스케어의 필요성이 증대되고 있다. 디지털 헬스케어로 기존 병원 진료의 온라인 원격 진료/처방이 지속 증가하고 있을 뿐만 아니라 관련 빅데이터를 모아 개인 건강과 질병 상태 정보를 취합하여 건강 관리 및 치료를 하는 디지털 치료제 개발이 급속 진행되고 있으며 관련 벤처 창업도 활발히 진행되고 있다. 이러한 디지털 헬스케어, 디지털 치료제 산업의 활성화는 각 개인의 신체 상태를 상시 측정하고 이 정보를 관련 시스템과 연동 할 수 있는 웨어러블 디바이스, 특히 스마트워치의 보급 증대에 힘입은 바가 크다. 본 연구에서는 스마트워치의 기술혁신이 디지털 헬스케어의 수용성에 어떻게 영향을 미치는지 확장된 통합기술수용모델을 적용하여 분석하고, 혁신 사례로 스마트워치를 활용한 디지털 수면 치료제 벤처 개발 현황을 제시하였다. 본 연구를 통해 확인한 결과는 다음과 같다. 첫째 디지털 헬스케어 스마트워치의 개인혁신성, 효용가치, 사용편의 등 ICT 변인들에 대한 기술발전의 매개 영향은 유의한 것으로 나타났다. 둘째 ICT 변인들과 기술발전 매개변수는 디지털 헬스케에 스마트워치 수용의도에 대부분 정(+)의 영향을 미치는 것으로 확인되었다. 단 기술발전은 개인혁신성에는 크게 매개하지 않는 것으로 나타났다. 이러한 혁신기술의 디지털 헬스케어 스마트워치 수용의도 영향 평가 결과는 스마트워치 각종 서비스 상품기획과 마케팅에 유효하게 참조 할 수 있을 것으로 보이며 추후 세분화 연구를 통하여 더욱 소비자 특화된 제품과 서비스를 창출하는데 기여 할 수 있을 것으로 사료 된다.

The purpose of this study is to examine diverse factors influencing the adoption of IPTV services and relationships among them. To achieve the purpose, this study modified and applied the established theory of the Extended Technology Acceptance Model(ETAM) incorporating socio-cultural factor, flow experience and perceived behavioral control as related constructs. The suggested model was empirically tested through the structural equation modeling approach. The results are as follows: First, the socio-cultural factor and the perceived behavioral control have significant direct influences on the adoption of IPTV services. Second, the flow experience does not have a significant indirect influence mediated by the attitude toward IPTV services. Third, the socio-cultural factor has the significant relationships with the perceived usefulness and the perceived ease of use. Finally, the flow experience was influenced by the perceived usefulness and the perceived ease of use.

This study investigated the antecedents of VR(virtual reality) headsets acceptance and the causal relationships among self-efficacy, content diversity, the perceived usefulness, the perceived easy of use, the perceived playfulness and the adoption intention. We collected 238 survey responses and formed structural equation modeling with AMOS 23.0. The results of the analysis can be summarized as follows. The diversity of contents and self-efficacy had significant effects on perceived usefulness, perceived ease of use and perceived enjoyment, thus increasing the intention of acceptance. Perceived usefulness, perceived ease of use and perceived enjoyment had significant effects on the intention of acceptance. Perceived ease of use indirectly had an effect through increasing perceived enjoyment. The price did not affect the adoption intention and marketing communication increased the intention of acceptance. The results are expected to provide useful information to the companies related to VR.

The primary purpose of the study is to investigate museum visitors' intention to use of smart tourism contents by applying the extended technology acceptance model. The study conducted an online survey of a convenience sampling of individuals who visited the National Museum of Korea, and it conducted confirmatory factor analysis and structural equation modelling to test hypotheses of the study. The results showed that information quality of immersive digital gallery in the National Museum of Korea had a significant regression weight on both perceived ease of use and perceived usefulness, and perceived ease of use had a significant regression weight on perceived usefulness. Moreover, both perceived ease of use and perceived usefulness had a significant regression weight on intention to use. The findings indicate that it is necessary to develop smart tourism contents with easily accessible and usable digital applications for promoting smart tourism in the museum.

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.

As one of Virtual Reality devices, HMD(Head-Mounted Device) helps users to experience an extended actual environment by providing them with virtual environment flexibly through the device. HMD considers user experience as importance as well as technical factors. Therefore, this study intended to analyze how the factors such as information quality, enjoyment, self-efficacy can have influence on the adoption of VR device using the extended technology acceptance model. The results showed that information quality and enjoyment have significant influences on perceived ease of use and usefulness. Self-efficacy only affect perceived ease of use. In addition, perceived ease of use and usefulness have influences on intention to use.

Purposes: The convenience of smartphones have lead to people's overdependence on devices, which may cause obstacles in daily life. It is useful to manage smartphone overdependence by using mobile health applications. We aimed to investigate the acceptance of mobile health applications designed to help in the management of smartphone overdependence. Methodology/Approach: We developed the extended model based on the Unified Theory of Acceptance and Use of Technology 2. The modified model had six hypotheses with six variables: result demonstrability, performance expectancy, effort expectancy, social influence, perceived risk, and behavioral intention to use. We randomly included 425 smartphone users in an online survey in 2020. A structural equation model was used to estimate the significance of the path coefficients. Findings: Performance expectancy and social influence had a very strong direct positive association with behavioral intention to use. Result demonstrability had a direct positive association with performance expectancy. Perceived risk had a strong direct negative association with performance expectancy. Performance expectancy and social influence were the main factors directly influencing the acceptance of mobile health applications for the management of smartphone overdependence. Practical Implications: We demonstrated smartphone users' acceptance of mobile health applications for smartphone overdependence management. Based on these results, we could develop mobile health applications more effectively.

UML은 범용의 목적으로 설계된 모델링 언어이지만 않은 도메인 영역에서 사용되고 있다. 그것은 UML을 각 도메인의 특성에 맞게 확장할 수 있는 프로파일이라는 메커니즘을 자체적으로 보유하고 있기 때문이다. UML 표준 명세에 기술되어 있는 확장 메커니즘과 프로파일은 그 자체로 매우 잘 설계된 모델이나 그대로 설계 도구에 도입하기에는 부적합한 면이 않다. 본 논문에서는 UML 기반의 설계 도구에서 프로파일을 수용할 수 있도록 확장 메커니즘 모델을 개선하고 프로파일을 정의할 수 있는 정형적인 방법들을 제시한다.
