Aziz Naciri 한국보건의료인국가시험원 2021 보건의료교육평가 Vol.18 No.-

As an alternative to traditional teaching, e-learning has enabled continuity of learning for health professions students during the coronavirus disease 2019 (COVID-19) pandemic. This review explored health professions students; perceptions, acceptance, motivation, andengagement with e-learning during the COVID-19 pandemic. Following the Preferred Reporting Items for Systematic Reviews andMeta-Analyses guidelines, a systematic review was conducted by consulting 5 databases: PubMed, ERIC (Ebsco), Science Direct, Scopus, and Web of Science. The quality of the included studies was assessed using the Medical Education Research Study Quality Instrument. The research protocol was previously registered in the PROSPERO registry (CRD42021237055). From 250 studies identified,15 were selected with a total of 111,622 students. Mostly positive perceptions were reported in 7 of 12 studies, which mainly focused ontechnology access, possession of basic computer skills, pedagogical design of online courses, online interactions, and learning flexibility. However, predominantly negative perceptions were identified in 5 of 12 studies, which pointed out constraints related to internet connections, the use of educational platforms, and acquisition of clinical skills. Satisfactory levels of acceptance of distance learning were reported in 3 of 4 studies. For student motivation and engagement, 1 study reported similar or higher motivation than with traditionalteaching, and another study indicated that student engagement significantly increased during the COVID-19 pandemic. Health professions students showed a positive response to e-learning regarding perceptions, acceptance, motivation, and engagement. Future research is needed to remediate the lack of studies addressing health professions students’ motivation and engagement during theCOVID-19 pandemic

Purpose: Learning motivation is an important factor in the teaching learning process in a digital environment. This study aims to examine self-determined motivation levels and associated factors among health professions students in distance learning activities. Methods: A cross-sectional, analytical, quantitative, multicenter study was conducted among health professions students from February 15, 2022, to July 31, 2022. Students’ self-determined motivation was assessed using a self-administered instrument. It consisted of 16 items categorized into four dimensions: intrinsic motivation, external regulation, identified regulation, and amotivation. It was based on 7-point Likert scale, ranging from 1 (strongly disagree) to 7 (strongly agree). Student engagement was examined using 15 items classified into the following subscales: behavioral, emotional, and cognitive engagement. A correlation between student motivation and engagement was performed. Univariate and multivariate logistic regression analyses were used to identify factors associated with students’ self-determined motivation in distance learning activities. Results: Of 1,121 students invited to the study, 1,061 valid questionnaires were received, giving a response rate of 94.6%; 595 participants (56.1%) were self-determined in distance pedagogical activities. Multiple regression analysis showed that ethnicity (adjusted odds ratio [aOR], 0.25; 95% confidence interval [CI], 0.08–0.73; p=0.012), educational level (aOR, 1.65; 95% CI, 1.16–2.34; p=0.005), distance learning environment (aOR, 1.65; 95% CI, 1.19–2.29; p=0.003), and student engagement: (aOR, 2.9; 95% CI, 2.21–3.80; p<0.001) were the significant factors associated with students’ self-determined motivation in distance learning. Conclusion: This study predicted some factors influencing students’ self-determined motivation. Health professions teachers need to be encouraged to adopt effective pedagogical practices in order to maintain and develop student motivation.

Purpose Distance learning describes any learning based on the use of new multimedia technologies and the internet to allow students to acquire new knowledge and skills at a distance. This study aimed to determine satisfaction levels with distance learning and associated factors among nursing and health technician students during the coronavirus disease 2019 pandemic in Morocco. Methods An descriptive study was conducted between April and June 2022 among nursing and health technician students using a self-administered instrument. The student satisfaction questionnaire consists of 24 questions categorized into 6 subscales: instructor, technology, course setup, interaction, outcomes, and overall satisfaction. It was based on a 5-point Likert scale, ranging from 1 (strongly disagree) to 5 (strongly agree). Univariate and multivariate logistic regression analyses were conducted to identify factors associated with student satisfaction during distance learning. Results A total of 330 students participated in this study, and 176 students (53.3%) were satisfied with the distance learning activities. A mean score higher than 2.8 out of 5 was obtained for all subscales. Multiple regression analysis showed that students’ year of study (adjusted odds ratio [aOR], 2.34; 95% confidence interval [CI], 1.28–4.27) and internet quality (aOR, 0.47; 95% CI, 0.29–0.77) were the significant factors associated with students’ satisfaction during distance learning. Conclusion This study highlights the satisfaction level of students and factors that influenced it during distance learning. A thorough understanding of student satisfaction with digital environments will contribute to the successful implementation of distance learning devices in nursing.

Inhibition of Eimeria tenella Development in vitro Mediated by Chicken Macrophages and Fibroblasts Treated with Chicken Cell Supernatants with IFN-g Activity

<P>Pretreatment of chicken macrophages or fibroblasts with supernatants from concanavalin A-stimulated spleen cells or from the virus-transformed cell line reticuloen-dotheliovirus as source of interferon gamma (IFN-&ggr;) slows down subsequent sporozoite replication in the cells. To identify the presence of IFN-&ggr;, we combined four typical activities of IFN-&ggr;: inhibition of cytopathic effect of vesicular stomatitis virus on IFN-&ggr;-treated fibroblasts, cytostatic activity of IFN-&ggr;-activated macrophages, induction of major histocompatibility complex II antigen expression on IFN-&ggr;-activated fibroblasts and macrophages, and induction of nitrite production in macrophages. We have shown that chicken fibroblasts and macrophages possess a microbiostatic capacity once they are able to prevent the otherwise unchecked intracellular replication of Eimeria tenella following activation with culture supernatants identified as containing a strong IFN-&ggr; activity. /// El pretratamiento de macrófagos aviares o de fibroblastos con sobrenadantes de células esplénicas estimuladas con concalabalina A o de una linea celular transformada por el virus de retículoendoteliosis como una fuente de interferón gama (IFN-&ggr;), disminuye la replicación subsecuente de los esporozoitos en las células.

The pure BaTiO3 and Ho doped BaTiO3 (Ba1-xHoxTiO3 with x = 0, 0.25, 0.50, 0.75, 1, 1.5 and 2%), powders were preparedthrough the sol-gel process and structurally characterized by Thermogravimetric analysis (TGA), Differential thermal analysis(DTA), X-Ray diffraction (XRD), Fourier Transform Infrared (FT-IR) and Raman spectroscopy. The optical propertieshave been investigated using Ultraviolet-Visible (UV-Vis) transmittance-reflectance spectroscopy. X-ray diffraction (XRD). The results revealed that the prepared powders, calcined at 1000 °C for 4 hours, crystallized in the pure perovskite structurewithout the presence of secondary phases and showed a slight transition from the quadratic phase (pure BT) to the pseudo-cubic phase for the doped samples. From these results, we can also notice that Ho may occupy both Ba and Ti crystallographicsites. Raman and Fourier Transform Infrared (FT-IR) results are in accordance with those obtained from XRDcharacterizations. The values of the bandgap energies for the doped samples are lower than that of the pure BaTiO3 (3.26eV), thus confirming energy softening effect of Ho.
