“…Recent research mostly focusing on the spread of respiratory particles on its infection risk and the mitigation strategies. In contrast to invasive method through vaccine shots, non-pharmaceutical interventions remain as the critical strategy in flattening epidemic curve [4]. In the context of respiratory-emitted pathogens, mode of transmission including breathing, talking, coughing, and sneezing are some of the transmission modes being widely discussed in the literature.…”

Prediction of airborne transmission in different environmental condition remains as the research challenge in the field. This has motivated the present study to obtain the direct impact of flow field to the physical nature of transmission. ANSYS Fluent 2022 R1 software is utilised in this research to numerically investigate and visualize flow pattern in a closed environment with cross ventilation and its effect to the emitted droplets deposition. The effect of different indoor parameters towards airborne transmission are investigated, which include wind velocity, air relative humidity (RH), and exposure time after emission. Simulation result revealed increasing wind velocity according to Beaufort wind scale of 1.0 to 3.9 m/s, increases transmission rate due to enhanced convection effect. Surrounding air with higher RH leads to a larger mean diameter of particles due to hygroscopic growth effect, while evaporation effect dominates in lower air RH, leading to particle shrinkage. In a light wind breeze, droplet mass of 5.15 mg deposited on receiver body within 0.5 s of transmission when RH is 40%, while only 3.29 mg droplets reached receiver in RH of 99.5%. Droplet particles settle on the floor within 1.50 s revealed 0.66 mg deposited mass in higher RH, while 0.26 mg of droplets deposited in lower RH. Deposition at transmitter body is possible due to recirculation effect of incoming wind generated between transmitter and receiver, leading to 3.7 times higher deposited mass in lower RH as compared to in higher RH. This research highlights application of Euler-Lagrange model to represent the trajectory of cough droplets influenced by indoor condition with horizontal wind, in the effort to strengthen safety and health judgement in the event of a pandemic.

“…In other words, the Covid-19 pandemic has expedited the shift to teaching with technology, as educators and students were forced to have their lessons online. In the Malaysian educational setting, all citizens were ordered to stay at home during the Movement Control Order (MCO) in 2020 [1]. During this time, all educational institutions were closed; hence, all students and educators had to have classes online [2].…”

Technology plays a vital role in educational institutions today. Educators are required to integrate technology in their teaching and learning sessions and teach their students 21st-century skills simultaneously, on top of teaching the subject matters. Hence, 21st-century TPACK was introduced as a framework for educators to measure their knowledge and skills when using technology. However, it is observed that some educators have difficulties when using technology due to a lack of knowledge and experience in using technology to teach. Hence, this study aimed to investigate the importance of education qualifications and teaching experience at the 21st-century TPACK level among English language educators in Malaysia. A total of 225 respondents among English language secondary school teachers were involved in this study, which was conducted quantitatively using an adapted questionnaire as the research instrument. The findings of this study revealed that the highest education qualifications play a role in the 21st-century TPACK level, while teaching experience did not. The results of this study showed the importance of upgrading and updating teacher's knowledge to teach with technology in the 21st century.

Healthcare workers (HCWs) are known to be at a high risk of being exposed to the SARS-CoV-2, or the COVID-19 virus because they are required to interact with their patients at a distance of less than two meters, for more than ten minutes at a time. Due to limited resources, most HCWs are inadequately protected. This study describes the development and the performance of an affordable full-body isolation pod (isopod). The isopod structure consists of composite side panels and aluminum poles and strips. A clear tarpaulin sheet is used to seal its structure. Two identical a high-efficiency particulate air (HEPA) filters are used to filter the air that goes through the isopod while the pressure inside it is maintained within the range described by the Airborne Infection Isolation (AII) room of the United Stated of America Centers for Disease Control and Prevention (CDC). This isopod could be the solution for hospitals in developing countries to enhance the protection among HCWs from the deadly virus since it is attainable and satisfies the CDC requirements.
