“…This is supported by Nugroho and Mutiaraningrum (2020) and Nugroho, Ilmiani, and Rekha (2020) reporting that online learning consumes a lot of time to prepare the learning materials. Moreover, the unfamiliarity of using online learning platforms such as sending documents/files, creating tasks deadline, checking students' presence, submitting tasks, and archiving students' work becomes another great challenge for teachers in their online class (Sun et al, 2020). The teachers also reported that speaking was the most challenging skill to teach as many students were not confident to speak up in online speaking practices.…”

Myriad studies reported abrupt transition of face-to-face classrooms to online learning due to pandemic and the results were various, contextually-bounded from country to another. Yet, studies exploring the aforementioned issue in Indonesian EFL context are still scarce. This study explores issues and challenges experienced by Indonesian EFL teachers in conducting English online learning during the pandemic within qualitative approach. Twenty-five secondary English teachers from urban, suburban, rural and remote area participated in this study. Subsequently, online questionnaire and semi-structured virtual interviews were employed to collect data. Then, the data were analyzed descriptively and thematically. The results showed that the participants had positive responses to online learning to maintain learning processes in pandemic time. In terms of teaching language skills, the participants argued that speaking is the most challenging to teach online. Moreover, the study identified three types of online learning challenges related to technical aspects, teachers and students. Pedagogically, this study implied that pandemic time has given teachers disguised blessings as they had an opportunity to upgrade their information technology skills and literacies.

“…Besides, unstable internet and limited quota of the internet brought another headache for both students and instructors. Due to these challenges, students lost their motivation and instructors lost their appetite and interest to deliver the classes (Sun et al, 2020). As a solution, a suggestion was given to develop the instructors' and students" skills and consider their readiness before implementing online classes (Lucena and Leal, 2020).…”

The widespread COVID-19 pandemic has affected all fields of life including education. Almost all the countries were obliged to close the doors of schools and institutions and alternatively use online teaching. The students, during the COVID-19 era, came across many difficulties and challenges that affected their performance dramatically. The current study aims to find out the difficulties and challenges encountered by Kurdish EFL learners in the universities of Charmo, Sulaimaniya, and Salahaddin in Kurdistan of Iraq. The mixed-Methods approach has been used to gather the data that included questionnaires and interviews. 110 students participated in the Likert-scale questionnaire and 9 instructors participated in the online interviews; they were all from the three universities mentioned above. The results showed that the main difficulties are the lack/shortage of good high-speed internet connections, internet instability, electricity power going off frequently on daily basis, not being trained, and being skilful enough to use the technological tools required effectively. Additionally, the instructors also encountered all the difficulties mentioned; plus, they were also considered as another source of the difficulty. The instructors were viewed by the students as not being trained, skilful, and prepared to teach through online classes successfully. They were also accused of not motivating, engaging, monitoring, and assessing the students properly due to their unskillfulness on how to teach online efficiently. Additionally, family"s underestimation of online classes and students" not having spare rooms for online studies are also considered as other problems hindering online learning. The study ends with the conclusion and findings of the study.

Background Application of Artificial Intelligence (AI) and the use of agent-based systems in the healthcare system have attracted various researchers to improve the efficiency and utility in the Electronic Health Records (EHR). Nowadays, one of the most important and creative developments is the integration of AI and Blockchain that is, Distributed Ledger Technology (DLT) to enable better and decentralized governance. Privacy and security is a critical piece in EHR implementation and/or adoption. Health records are updated every time a patient visits a doctor as they contain important information about the health and wellbeing of the patient and describes the history of care received during the past and to date. Therefore, such records are critical to research, hospitals, emergency rooms, healthcare laboratories, and even health insurance providers. Methods In this article, a platform employing the AI and the use of multi-agent based systems along with the DLT technology for privacy preservation is proposed. The emphasis of security and privacy is highlighted during the process of collecting, managing and distributing EHR data. Results This article aims to ensure privacy, integrity and security metrics of the electronic health records are met when such copies are not only immutable but also distributed. The findings of this work will help guide the development of further techniques using the combination of AI and multi-agent based systems backed by DLT technology for secure and effective handling EHR data. This proposed architecture uses various AI-based intelligent based agents and blockchain for providing privacy and security in EHR. Future enhancement in this work can be the addition of the biometric based systems for improved security.
