The theory behind and factors influencing the use of telemedicine during the COVID-19 pandemic: A systematic review.

A paradigm change in patient health care toward telemedicine services was necessary in 2020 due to the COVID-19 pandemic, which broke out at the end of 2019. Theories used in determining the determinants of telemedicine utilization are various theories. Research conducted on the use of telemedicine still has doubts about the basic theory used in analyzing the factors that influence telemedicine, especially during the Covid-19 pandemic. The goal of this study is to outline the fundamental principles of telemedicine utilization during the Covid-19 outbreak and the variables that affect it. This Literature Review uses the scoping review method with the tool procedure, namely PRISMA. Based on the conducted literature review, there are 12 scholarly papers addressing the variables that affect the utilization of telemedicine services. During the Covid 19 epidemic, more individuals in many nations used telemedicine services. Anderson's theory of health care use and the idea of technology adoption or acceptance serve as the foundational theories for forecasting the variables that affect the use of telemedicine. The utilization of telemedicine is influenced by 29 different factors that come from different theories. The desire for health, exposure to COVID 19, co-morbidities, social media usage, avoiding contamination, time efficiency, ease of use of services, social impact, and hedonic incentive are among the factors associated to the COVID 19 pandemic.

The COVID-19 Health Protocol among University Students: Case Studies in Three Cities in Indonesia.

The COVID-19 pandemic has caused lifestyle changes for everyone and led to the practice of regulated health protocols for preventing the spreading or severity of the COVID-19 pandemic. This study examines the differences in health protocols and health practices among university students. The designed online survey was conducted among 292 university students in three cities in Indonesia, i.e., Yogyakarta, Semarang, and Surakarta. A forced-entry multivariate regression was conducted using all RANAS (risk, attitude, norms, ability-self-regulation) sub-factors as independent variables and health protocol obtained from PCA as the dependent variable. The results showed that the students' health protocol and health practices were practiced with varying frequency. A face mask covering the chin and nose was the most practiced health protocol, while reducing mobilization by maintaining distance was the most violated health protocol among students. We also found that four health protocol practices are highly correlated, i.e., handwashing in public spaces, physical distancing, frequency of using the mask, and avoiding crowded places. In addition, three significant psychological factors were identified, which were positively associated with the student's health protocol practice, i.e., belief about time (attitude) (OR: 0.119; CI: -0.054-0.136; p ≤ 0.05), personal norm (norm) (OR: 0.232; CI: 0.149-0.539; p ≤ 0.01), and action control (self-regulation) (OR: 0.173; CI: 0.046-0.427; p ≤ 0.05), where the personal norm is the most significant one. Finally, to minimize the COVID-19 transmission among students, especially when they back to onsite learning, it was important to create students' sense of ethical self-obligation to follow and practice standard health hygiene correctly and regularly.

Highly antimicrobial and strong cellulose-based biocomposite film prepared with bacterial cellulose powders, Uncaria gambir, and ultrasonication treatment.

This work characterized bacterial cellulose (BC)/Uncaria gambir (G) biocomposite film prepared with ultrasonication treatment. Films were prepared from BC powder suspensions in distilled water without and with various loadings (0.05 g, 0.1 g, 0.2 g, 2 g) of G powder then treated using an ultrasonic probe at 1000 W for one hour. The results revealed that the ultrasonication treatment of the suspension greatly increased tensile strength (TS), elongation at break (EB), and toughness (TN) of a BC film by 3097%, 644%, and 32,600%, respectively, compared to non-sonicated BC film. After adding 0.05 g G into the sonicated BC powder suspension, TS, EB, and TN of the biocomposite film were improved to 105.6 MPa, 14.3%, and 8.7 MJ/m3, respectively. The addition of the G increased in antimicrobial activity of the film. This study indicates that biocomposite film is potentially useful for nanopaper production with good antimicrobial and high tensile properties.
