Present study is targeted to detrimental effects of EMF radiation on various biological systems mainly due to online teaching and learning process by suppressing the immune system. During COVID-19 pandemic the increased usage of internet due to online education and online office leads to more detrimental effects of EMF radiation. Further inculcation of soft computing techniques in EMF radiation has been presented. A literature review focusing on the usage of soft computing techniques in the domain of EMF radiation has been presented in the article.

This article discusses the strategies used by five non-millennial teachers (aged 54-59 years old) of a junior high school in coping with the online teaching during the COVID-19 pandemic, in Ngawi, East Java, Indonesia. The teachers were interviewed, and the data were transcribed and analyzed by creating a data repository, expanding the codes, describing the coded data, and drawing conclusions. The results revealed that the teachers had several strategies used, which were to increase students’ interest in learning, provide students with knowledge and attention, create efficient learning resources, and use SIMPEL (Sistem Informasi Manajemen Pembelajaran or Learning Management Information System), which is specifically available only in Ngawi. SIMPEL was specially developed by the Ngawi district education office, to ensure that the learning processes in Ngawi Regency continue to run optimally during the COVID-19 outbreak. SIMPEL substituted the use of online YouTube videos and materials because the materials were already provided by the system, decreasing the need for the teachers to depend on other resources. Despite these teachers also using other online platforms, hence issues such as the slow internet connection, running out of quotas and blackouts, hindered their efforts to use these platforms at times. Hence, WAG was the most used media to conduct their online learning due to its simplicity and availability. These teachers continued to strive to learn digital technologies ever since they changed from their previous face-to-face teaching strategies.

The implementation of online English instruction in remote areas during the COVID-19 pandemic, which mandates school closures, remains unknown, especially given these areas’ reputation for inadequate educational facilities. Additionally, the preparations, implementation, and challenges experienced by English as a Foreign Language (henceforth, EFL) teachers in rural areas remain unclear. This study therefore aimed at exploring the experiences of EFL teachers in rural areas on (1) their readiness for conducting online teaching, (2) their implementation of online teaching, and (3) the challenges during the implementation of online teaching due to the COVID-19 pandemic. The research was conducted in Indonesia with eight English teachers in rural schools. This study was a qualitative study that employed a phenomenological study approach and used semi-structured interviews to collect the data. The findings indicate that EFL teachers, during this pandemic time, were able to conduct fully online English teaching because they possessed sufficient knowledge of English instruction using technology. Additionally, these teachers might leverage various technologies and adapt those tools to transform their usual face-to-face English instruction into online instruction. Nonetheless, these teachers in rural schools frequently encountered challenges with internet connectivity, student-owned technology devices, student enthusiasm, and student netiquette when enrolling in online English teaching. Additionally, this article discusses some practical considerations for implementing online English teaching during a pandemic.

<p style="text-align: justify;">Coronavirus disease (COVID-19) preventive measures influenced teachers directly. The sudden shift to new teaching environment emerged unknown challenges influencing teachers’ work differently. As self-efficacy is a key factor of successful teaching, the goal of our study was to examine the relationship among teachers’ efficacy-related experiences, work satisfaction and workload during the pandemic. 769 teachers (55 men and 677 female, 32 undefined) completed the online version of the Norwegian Teacher Self-Efficacy Scale and the Relative Self-Efficacy Scale. Findings indicated significant positive correlation between job satisfaction and self-efficacy as well as job satisfaction and the sense of competency. Kruskal-Wallis Test proved higher level of self-efficacy among teachers with more experience in online teaching in the past. According to SEM analysis, job satisfaction is predicted by efficacy beliefs concerning the sense of competence, motivation, coping and conflict resolution. Our findings indicate that experience in online teaching methods can enhance self-efficacy, which contributes to higher job satisfaction.</p>

The study questionnaire containing 20 questions was prepared, prevalidated and distributed to all the study participants as google form. Data from completed questionnaires was entered into an excel sheet and analyzed using descriptive statistics.Analysis of data from 279 students revealed that the 69% of the students used smartphones to attend online classes, 96% of them reported having internet problems and 42% of the students enjoyed the online classes. Understanding of the topic and knowledge gained during online classes were rated average and above average by 59% and 53% of the students respectively. Many students felt that long screen hours have made the classes less interesting and caused health issues like headaches, eyestrain, and backache. They also felt that online classes were less interactive and did not provide much clinical and practical knowledge.Students showed a negative response to online classes. There is a need to make online classes more interactive and interesting by using certain strategies like problem-solving activities, quizzes, discussions, surveys, and polls. Faculty should be trained in good online teaching practices to ensure its success.
