The purpose of this study is to identify the direct effects of PSM on job satisfaction (JS) and perceived job performance (PJP) in public institutions and to identify indirect effects of the mediator. In particular, we define the person-organization fit (POF) used as the mediator as the fitness of the personnel system and identify the influence of POF in the relationship between PSM, JS, and PJP. The questionnaires used in this study were conducted for the members of Changwon Public Health Center and empirical analysis using structural equation modeling was conducted and the following results were obtained. First, PSM in the integrated public service organization has a positive effect on JS and PJP. Second, PSM shows that JS and PJP of organization members are improved through mediating effect of POF. It can be concluded that PSM can improve JS and PJP through institutional fit between members and organizations.

The purpose of this study is to investigate the influence of exogenous variables on the intention to use AI speaker. An online survey was administrated to 305 AI speaker users in order to examine the effect of the personal characteristics (self-efficacy, innovativeness, suitability, and enjoyment) and social impact (social conformity and social image) on perceived usefulness and easiness. The results indicate that (1) self-efficacy and social conformity have positively effect on perceived easiness; (2) suitability and social image have positively effect on perceived usefulness whereas innovativeness has negatively effect on perceived usefulness; (3) perceived usefulness and perceived easiness have significant effect on the intention to use AI speaker.

As the level of people's demand for service quality provided by public institutions increases, interest in improving organizational effectiveness of internal members is increasing. In this context, this study aims to identify the predisposing factors affecting the job satisfaction and perceived job performance of public institution members. In this study, public service motivation, work autonomy, and person-system fit were presented as antecedents to verify the organizational effectiveness, and the results were tested by regression analysis. As a result, all three antecedents have significant effects on job satisfaction and perceived job performance. Public service motivation, work autonomy has a relatively higher impact on job satisfaction. On the other hand, person-system fit has a relatively higher influence on perceived job performance. In particular, the results of this study confirmed that PSM theory is consistent with the main trends and is significant in organizations created through artificial integration. This result suggests the need to maintain the effectiveness of the public organization in the future due to the change of integration of public organizations.

Nowadays, as many robots are developed for desktop, users interact with the robots based on speech. However, due to technical limitations related to speech-based interaction, an alternative is needed. We designed this research to design a robot that interacts with the user by using unconditional reflection of biological signals. In order to apply bio-signals to robots more effectively, we evaluated the robots' overall service evaluation, perceived intelligence, appropriateness, trustworthy, and sociability according to the degree of the robot's embodiment level and the response speed of the robot. The result showed that in terms of intelligence and appropriateness, 3D robot with higher embodiment level was more positively evaluated than 2D robot with lower embodiment level. Also, the robot with faster response rate was evaluated more favorably in overall service evaluation, intelligence, appropriateness, trustworthy, and sociability than the robot with slower response rate. In addition, in service evaluation, trustworthy, and sociability, there were interaction effects according to the robot's embodiment level and the response speed.

Based on literature relating to the theory of planned behavior(TPB) and the TAM, this study extends the applicability of the TAM in a mobile banking context, by adding one trust-based construct('perceived credibility') and two resource-based constructs('perceived efficacy' and 'perceived cost') and technical suitability constructs to the model, while paying careful attention to the placing of these constructs in the TAM's existing nomological structure. Data collected from 182 users in Korea were tested against the extended TAM, using the structural equation modeling approach. The results strongly support the extended TAM in predicting users intentions to adopt mobile banking. Several implications for IT/IS acceptance research and mobile banking management practices are discussed.

본 연구는 기술수용모델(Technology Acceptance Model)을 기반으로 <클림트 인사이드(2017)>전시에서 사용된 <스토클렛 저택의 장식벽화(Stoclet Frieze)> VR 앱에 대한 인지된 유용성(이하 PU)과 인지된 이용용이성(이하 PEOU)의 평가에 초점을 맞추었다. VR 앱의 학습적합성(SFL)이 감상적합성(SFA)보다 높게 평가된 PU의 경우, 학습유용성(UFL)과 감상유용성(UFA)의 모든 요인이 만족도(DOS)에 긍정적인 영향을 미침으로써, 전시환경에서의 VR 앱의 학습에 대한 내적 동기 부여 및 감상 지원에 대한 잠재력이 확인되었다. 또한 PEOU의 모든 요인들은 DOS뿐만 아니라 DOI와도 유의미한 상관관계를 가졌다. 본 연구를 통해 TAM의 PU와 PEOU의 ATUA(DOS 및 DOI) 및 BITUA(ITRA(1) 및 ITRA(2))에 대한 영향력이 검증됨에 따라, 두 변수는 사용자의 VR 앱에 대한 기술 수용에 대한 예측을 가능케 했으며, 결론적으로 예술작품 원작을 재매개한 VR 앱에 대한 평가모델로써 TAM의 적합성이 입증되었다.

This study analyzed whether the suitability of strategy is playing a regulative role between IT characteristics & user characteristics and non-financial performance empirically. To this end, this study set up IT characteristics and user characteristics as independent variables, and set up non-financial performance as the performance variable of KMS, and also set up the suitability of the management strategy & informatization strategy of a business as moderating variables. This study defined the detailed factors in IT characteristics as IT maturity and IT/IS infrastructure while defining the detailed factors in user characteristics as perceived profit, organizing of learning, and user professionalism. In addition, this study defined non-financial performance as an organization member satisfaction, and KMS availability. As a result of the analysis, IT maturity & IT/IS infrastructure, which are defined as IT characteristics, and perceived profit, organizing of learning and user professionalism, etc., which were defined as user characteristics, were found to be variables playing a regulative role in non-financial performance.

This study investigates the influential factors for the user's satisfaction in usage of PDA in Korea Postal Services. This is the case of user's acceptance of information technology that organization mandatorily implements for the sake of employee's productivity. The factors examined in this study include system quality, information quality, perceived usefulness, user satisfaction, and compatibility with work. All these factors were found significant for users satisfaction. Especially, we notice the close relationship between compatibility with work, perceived usefulness, and user satisfaction in case of nonvolitional IT usage.
