Examination of the usability of Tinkercad application in educational robotics teaching by eye tracking technique

Like all sectors, the education sector has been negatively affected by the Covid-19 pandemic. Considering the decision to conduct face-to-face training in schools remotely, teachers had many difficulties in moving course content to the online platform. Teachers who perform robotic coding applications are looking for ways to do these activities remotely. Simulators enable real objects to be animated in a computer environment. There are many paid and free platforms that simulate robotic coding tools. Arduino and Micro:bit, can be simulated on the Tinkercad platform. This study tests the usability of the Tinkercad platform by teachers. In usability tests, users are expected to complete the authentic tasks they must perform on the tested platform. In this study, 12 Information Technology teachers tried to complete 10 authentic tasks in the Circuits section of the Tinkercad platform. Eye movements have been recorded and analyzed while participants perform tasks. Surveys were applied to the participants and data were collected with the observation form during the tests. Consequently, the teachers who completed the usability tests stated that it is appropriate for the platform to be used by teachers and students over 10 years of age and that they can use the platform in their activities. © 2023, The Author(s).

Specialist physicians battle against the COVID-19 pandemic: the relationship between specialist physicians working conditions and levels of burnout during the COVID-19 pandemic.

OBJECTIVE: This study was planned to determine the burnout levels of physicians during the COVID-19 pandemic, and to contribute to taking the necessary measures by determining the associated factors. MATERIALS AND METHODS: This research was designed via Google Online Form as an online survey with questions of Sociodemographic Data Form, Maslach Burnout Inventory and Beck Anxiety Inventory and was conducted with 40 specialist physicians actively working at the Sakarya University Training and Research Hospital. The same questionnaire was re-applied online after two months, and 24 out of 40 physicians were accessed. The SPSS 25 (IBM, Armonk, NY, USA) program was used for the analysis of the data. RESULTS: According to the Maslach Burnout Inventory applied in the pre-test, it was found that the feeling of personal accomplishment was high, emotional burnout was normal, and depersonalization was low. Anxiety and burnout were found to be positively correlated, and there were no statistically significant differences in the average values of the pre-and post-test Maslach Burnout Inventory and Beck Anxiety Inventory scores. CONCLUSIONS: Detecting possible burnout in physicians working in a pandemic, identifying associated factors and taking required measures can be beneficial both for physicians and society from a biopsychosocial perspective.

Investigation of Education Faculty Students' Health Perception Levels and Healthy Lifestyles in the Covid-19 Process

Objective: With the increase of the Covid-19 epidemic, societies around the world have been exposed to different restrictions. Turkey has also implemented some restrictions in daily life to reduce the rate of coronavirus spread. This research was conducted to provide a better understanding of changes in health perception and healthy lifestyle habits of university students due to the Covid-19 restrictions. Methods: The research group consisted of 1032 (480 Female, 552 Male) volunteer students from the education faculties of Firat and Mustafa Kemal University. As data collection tool, an online questionnaire form, in which participants' demographic information, healthy lifestyles and health perception levels were questioned, was used. The data were analyzed using the SPSS package program. Results: Most of the research group did not do physical activity regularly and consumed two main meals a day and the most skipped meal was lunch with the rate of 55.2%. Students reported consuming foods such as cakes/cookies/biscuits most for their snacks, 28.5% of them consumed 1.5 liters of liquid daily. The students' perception of health scale total score average was 48.15 +/- 4.06, the scale sub-dimensions mean score control center mean score was 14.55 +/- 1.70, the certainty point average was 15.29 +/- 2.85, the average score of importance of health was 9.70 +/- 1.62, and the average score of self-awareness was 8.59 +/- 1.14. According to the gender variable, male students' perception of health scale and all sub-dimensions mean scores were higher than female students. It was observed that students who received nutrition education had higher mean scores than students who did not receive nutrition education. It was determined that students without a chronic illness had higher mean scores than students with a chronic illness except for the certainty and self-awareness sub-dimensions. Conclusion: The health perceptions of the students were at a moderate level, and their healthy lifestyle and physical activity levels were negatively affected. In line with these results, it is thought that the implementation of projects supporting a healthy lifestyle, as well as studies to increase the perception of health of individuals, will be beneficial in protecting and improving public health

Atmospheric Pressure Mass Spectrometry of Single Viruses and Nanoparticles by Nanoelectromechanical Systems.

Mass spectrometry of intact nanoparticles and viruses can serve as a potent characterization tool for material science and biophysics. Inaccessible by widespread commercial techniques, the mass of single nanoparticles and viruses (>10MDa) can be readily measured by nanoelectromechanical systems (NEMS)-based mass spectrometry, where charged and isolated analyte particles are generated by electrospray ionization (ESI) in air and transported onto the NEMS resonator for capture and detection. However, the applicability of NEMS as a practical solution is hindered by their miniscule surface area, which results in poor limit-of-detection and low capture efficiency values. Another hindrance is the necessity to house the NEMS inside complex vacuum systems, which is required in part to focus analytes toward the miniscule detection surface of the NEMS. Here, we overcome both limitations by integrating an ion lens onto the NEMS chip. The ion lens is composed of a polymer layer, which charges up by receiving part of the ions incoming from the ESI tip and consequently starts to focus the analytes toward an open window aligned with the active area of the NEMS electrostatically. With this integrated system, we have detected the mass of gold and polystyrene nanoparticles under ambient conditions and with two orders-of-magnitude improvement in capture efficiency compared to the state-of-the-art. We then applied this technology to obtain the mass spectrum of SARS-CoV-2 and BoHV-1 virions. With the increase in analytical throughput, the simplicity of the overall setup, and the operation capability under ambient conditions, the technique demonstrates that NEMS mass spectrometry can be deployed for mass detection of engineered nanoparticles and biological samples efficiently.
