Results
In this study, consent had been obtained from a total of 86 participants. However, maintaining the research implementation structure became difficult after the primary researcher resigned during the course of the project. The decision to discontinue the study was made due to the absence of a researcher to play a central role and the difficulty in establishing a sufficient framework to carry out the originally planned research and analysis.
