Empirical Study on the Acceptance of Mobility as a Service (MaaS) Based on the UTAUT2 Model
Toyama Masaki 한국마케팅학회 2022 ASIA MARKETING JOURNAL Vol.24 No.3
To achieve the widespread use of Mobility as a Service (MaaS), a novel transportation platform, it is important to increase consumers' intention to use MaaS. Therefore, this study clarifies the determinants of consumers’ intention to use MaaS based on the UTAUT2 model. The research model is tested using structural equation modeling based on data from a web-based questionnaire survey of Japanese consumers. The results show that performance expectancy, social influence, hedonic motivation, and price value have significant effects on the intention to use MaaS. Moreover, the relationship between the intention to use MaaS and independent variables is moderated by old age. Theoretical and practical implications are discussed based on the findings.

Background/Aims: The necessity for pharyngeal anesthesia during upper gastrointestinal endoscopy is controversial. This study aimedto compare the observation ability with and without pharyngeal anesthesia under midazolam sedation. Methods: This prospective, single-blinded, randomized study included 500 patients who underwent transoral upper gastrointestinalendoscopy under intravenous midazolam sedation. Patients were randomly allocated to pharyngeal anesthesia: PA+ or PA– groups (250patients/group). The endoscopists obtained 10 images of the oropharynx and hypopharynx. The primary outcome was the non-inferiorityof the PA- group in terms of the pharyngeal observation success rate. Results: The pharyngeal observation success rates in the pharyngeal anesthesia with and without (PA+ and PA–) groups were 84.0%and 72.0%, respectively. The PA– group was inferior (p=0.707, non-inferiority) to the PA+ group in terms of observable parts (8.33 vs. 8.86, p=0.006), time (67.2 vs. 58.2 seconds, p=0.001), and pain (1.21±2.37 vs. 0.68±1.78, p=0.004, 0–10 point visual analog scale). Suitablequality images of the posterior wall of the oropharynx, vocal fold, and pyriform sinus were inferior in the PA– group. Subgroupanalysis showed a higher sedation level (Ramsay score ≥5) with almost no differences in the pharyngeal observation success rate betweenthe groups. Conclusions: Non-pharyngeal anesthesia showed no non-inferiority in pharyngeal observation ability. Pharyngeal anesthesia may improvepharyngeal observation ability in the hypopharynx and reduce pain. However, deeper anesthesia may reduce this difference.
