: The study was approved by ethics committees at St. Luke’s International University (approval number: 19-A036) and conducted following the Declaration of Helsinki guidelines. Participants were provided written explanations of the survey’s purpose, research methods used, details of participating in and withdrawing from the survey, protection of personal information, and data management methods used in the study. The collected data were managed separately, and facility ID numbers and a correspondence table were created to ensure that individual participants could not be identified from the data. Further, data such as basic attributes were coded to maintain participant anonymity. Since participation was anonymous and voluntary, consent was implicitly obtained by receipt of completed questionnaires.
