ABSTRACT
The COVID-19 pandemic is expected to significantly impact cancer treatment due to the shortage of medical supply, including the anxiety of patients and their families-specifically those associated with the risk of infection. We conducted a questionnaire survey using the internet service formrun between March 1 and 31, 2021. A total of 126 hospitals and 65 patients responded to the survey. Telemedicine perception differed between hospitals and patients. Hospitals found telemedicine to be useful, whereas patients did not;the main reasons for this were inadequate examinations and consultations and difficulty in communicating symptoms. Although telemedicine is regarded as one of the most effective tools during the COVID-19 pandemic, there are still issues with its widespread application. Notably, it would be essential to collaborate with local hospitals to improve cancer treatment during this pandemic.
ABSTRACT
This study developed an online observable augmented reality dynamics experimental system that can be used in the current COVID-19 pandemic, where face-to-face experiments are difficult to conduct. The developed system enables the broadcast of mass point and rigid body measurements using an online depth camera, and remote observation using mobile devices. The mass point measurement enables students to quantitatively analyze results by utilizing 2D projected trajectories. Students can view the virtual trajectories by modifying the gravity or restitution coefficient, which is not possible in real experiments. The complex motion of the rigid body can be shown separately as the motion of the center of gravity and the moment of inertia with respect to the center of gravity. © 2021 IOP Publishing Ltd.
