ABSTRACT

The present study aims at investigating the positive side of Mr. Johnson, the Prime Minister of Britain, during the opening statement of COVID-19. Particularly, it sheds light on the positive constructions that that are employed by Mr. Johnson at three stages: the description, interpretation and explanation. The data in question are analysed descriptively and statistically. It is found that the active voice and the lexical verbs are mostly used in the description stage;the directive, expressive and declarative speech acts are equally used in the interpretation stage. It is concluded that the positive message are appropriately achieved via using the active voice, verbs, the expressive, declarative and directive speech acts in Mr. Johnson’s discourse. © 2022, Association Res Militaris.

ABSTRACT

Technology in teaching and learning is crucial as we are now focusing on 21st Century Learning. Moreover, the Covid-19 pandemic has affected many sectors, including education sectors, where most educators are continuously looking for approach and tools to enhance their teaching deliveries to ensure students can still learn effectively even though most of the classes are currently conducted online. Other than that, students also have problems with their visualization skills when learning engineering drawing, which caused a lack of understanding of the content, thus making it even harder for them to learn in this situation. Technology such as augmented reality is a well-received technology application due to its benefit in enhancing users’ learning experiences, enhancing visualization skills, and supplementing materials more effectively. Thus, this paper aims to describe Augmented Reality Engineering Drawing Apps (AREDApps) development process, a mobile augmented reality apps for orthographic projection topic in engineering drawing subject, highlight the students’ perception when using AREDApps during learning and introduce the engineering drawing learning framework based on AREDApps implementation in the classroom. The result indicates that students were mostly satisfied with augmented reality technology to learn orthographic projection. This is because AREDApps helps them supplement the information that cannot be delivered by using modules or PowerPoint presentation such as the three-dimensional representations of the task given to them. The findings of this paper strengthen the facts that augmented reality is a suitable technology to teach complex technical subjects, which requires supplementary materials that can help students to be able to visualize the task effectively. © 2022, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.

ABSTRACT

Cigarette smoking is a risk factor associated with different diseases, claiming millions of lives annually. Smoking status has been studied for a long time and proved to be a major cause of smokers' decreased immunity. In the present pandemic COVID-19 disease, there was an unclear belief about the effect of smoking on patients with COVID-19. Therefore, the current cross-sectional study aimed to evaluate the effect of cigarette smoking on the sequelae of COVID-19. This cross-sectional study involved 200 COVID-19 patients (114 males and 86 females) aged 13-77 years. A number of 87 patients were smokers, and the rest of them were non-smokers. All patients underwent a comprehensive laboratory assessment and diagnosis by full medical history by the physicians. The results indicated a significant difference (P<0.001) between smokers and non-smokers in terms of hypertension, anticoagulant, steroid therapy, pulmonary lesion, oxygen saturation, and duration of disease. As an overall conclusion, it can be stated that COVID-19 is less severe in smokers and they require less intensive treatment.

ABSTRACT

Objective: Coronavirus pandemic has spread globally. It has affected people mentally and economically. These types of pandemics often lead to post-traumatic stress traumatic syndrome among people. Research data is needed to know the PTSD due to the coronavirus pandemic among the general population. Materials and methods: This study is cross-sectional. Data was collected in 3 days from the general population of Karachi through an online questionnaire regarding age, gender, education, profession, precautionary measures, awareness related to COVID, satisfaction related to COVID, Health information awareness. IESR scale was used to assess post-traumatic stress syndrome. A total of 241 respondents were involved. Results: Moreover, 11.2% had partial PTSD, 4.1% had PTSD and 34.9% had PTSD high enough to suppress the immune system. Among the respondents majority belong to age group 20 to 30, female, student, undergraduate, were aware of COVID, tested positive for COVID, knew someone tested positive for COVID, applied precautionary measures, avoided going out, worried about your family members getting COVID, satisfied with health information available and were aware of health information available. Age group 20 to 30, Male gender, matric education level, housewives, tested positive for COVID, applying precautionary measures, applying social distancing, having present physical symptoms, worrying about your family members getting COVID, was associated with high IESR score and PTSD (p<0.05). Awareness related to COVID-19 and avoiding going out was associated with low IESR scores and were protective factors related to PTSD(p<0.05). Tested positive for COVID, presence of past physical symptoms, satisfaction with health information available, and awareness of health information available were not significantly associated with IESR score and PTSD (P>0.05) Conclusion: During the outbreak of the coronavirus pandemic more than half of the respondents reported partial to severe PTSD. Age group 20 to 30, Male gender, matric education level, housewives, tested positive for COVID, applying precautionary measures, applying social distancing, having present physical symptoms of COVID, worrying about your family members getting COVID are the vulnerable groups which need urgent attention related to PTSD. Awareness related to COVID-19 and avoiding going out are protective factors related to PTSD hence these factors can be considered by higher authorities to make psychological policies.

ABSTRACT

This paper presents an internet of things (IoT) based heart failure monitoring system using radio frequency identification (RFID). It is developed to assist doctors to monitor patient's health conditions with heart failure disease remotely. The monitoring process can be done without having the presence at the hospital especially during the COVID-19 pandemic crisis where the doctor and the caretaker can access the medical record of the patient whenever required. This project employs Arduino Mega as the microcontroller which is interfaced with several sensors as input such as temperature sensor, pulse oximeter sensor and pulse sensor. The patient only needs to place their fingertip on each sensor while the monitoring process is performed to obtain the reading of health data. These data will be sent to the microcontroller to be processed and compared with the threshold value of each sensor. If the data obtained exceeds the threshold value, a notification is sent via Blynk mobile application to notify the doctor or caretaker on the abnormalities of the patient's health condition for further action. ESP8266 Wi-Fi module is used to allow doctor to access and monitor their patient's data from the cloud server using Blynk mobile application. This mobile application displays and notify the health condition of the patient in real time. Besides, the health data also can be exported to Excel for analysis and evaluation. The result obtained from testing the system turned out to be satisfactory in monitoring patient's health condition with an almost accurate reading of health data. © 2021 IEEE.

ABSTRACT

This study evaluated a special form of lockdown that was applied in Jordan: one day of lockdown every week, which was applied on consecutive weekend days (i.e., Friday in Jordan, for 24 hours). We tried to assess the impact of this form of lockdown on the daily number of positive coronavirus disease 2019 (COVID-19) cases, using interrupted time series analysis. We included the period of March 5 to April 17, 2021, as the period affected by the Friday lockdown, which was applied to seven consecutive Fridays with a total of 168 hours. We used R version 4.0.5 (R Foundation for Statistical Computing, Vienna, Austria) for our analysis. We used Poisson model regression analysis, where the number of positive cases was used as the outcome variable, while the total number of tests, time, and lockdown were used as the predictor variables. We further performed quasi-Poisson regression analysis to confirm the first model. On Poisson model regression analysis, it was found that there was an evidence of an increase in the number of positive COVID-19 cases following the intervention of Friday lockdown, with a p value of <0.001 (relative risk, 1.569; 95% confidence interval, 1.549-1.590). On using quasi-Poisson regression, similar results were found with a wider confidence interval. We concluded that a single weekend day lockdown led to an increase in the number of daily cases of COVID-19. Therefore, we recommend authorities to adhere to evidence-based measures or to the WHO recommendations in the dealing with this pandemic.

ABSTRACT

The COVID-19 pandemic has resulted in 198 million reported infections and more than 4 million deaths as of July 2021 (covid19.who.int). Research to identify effective therapies for COVID-19 includes: (1) designing a vaccine as future protection; (2) de novo drug discovery; and (3) identifying existing drugs to repurpose them as effective and immediate treatments. To assist in drug repurposing and design, we determine two apo structures of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) main protease at ambient temperature by serial femtosecond X-ray crystallography. We employ detailed molecular simulations of selected known main protease inhibitors with the structures and compare binding modes and energies. The combined structural and molecular modeling studies not only reveal the dynamics of small molecules targeting the main protease but also provide invaluable opportunities for drug repurposing and structure-based drug design strategies against SARS-CoV-2.

ABSTRACT

This study is intended to answer the question of how political polarization is related to social media users posts about Covid-19. The researchers chose health cases related to Covid-19 instead of political issues (e.g. elections) to prove that this political polarization has spread to many areas. The research also wants to see the relationship between this political polarization and selective exposure. Theories applied in this study are polarization, filter bubble, and selective exposure. The study applied two methods: social media network analysis and content analysis. The network analysis included 82,156 posts, while the content analysis was carried out on 4,050 social media accounts. The research outcome proves the occurrence of political polarization. Social media users were divided into two major groups, namely pro-Jokowi and anti-Jokowi. Each group interacted with fellow users who had the same political choices and shared the same message content. Users with certain political choices tend to receive the same information as their political choices, and ignore information from other political parties. Another interesting finding from this study is how this polarization was sharpened by the use of hashtags. Each party (supporters and oppositions of Jokowi) uses hashtags to create solidarity and mobilization from each supporter. Research also proves the validity of the selective exposure and filter bubble hypothesis in the Indonesian context. © 2021 Complex Issues of Cardiovascular Diseases. All rights reserved.

ABSTRACT

The magnitude of the risks in the face of the COVID-19 disease is increasing every day, and foreshadowing a catastrophe facing humanity. It is clear, the levels of health services in different countries around the world are very different, therefore there will be many health risks in countries that are suffering in terms of health services. The objective of this study was to compare different therapy for patients with severe coronaviruses diseases (COVID-19). Nowadays, different medicines have been used to reduce the severity of symptoms of this disease such as Ribavirin, Chloroquine, Arbidol, Lopinavir/Ritonavir, Favipiravir, Remdesivir, Azithromycin, and Sputnik V. These medications are used in every region of the world to make some progress in finding a solution to (COVID-19), including Kurdistan region which is in the north of Iraq. As is the case in most third world countries, the health service is not at the required level, and despite that, we were able to make a comprehensive list of medicines used in many countries of the world and here in Kurdistan, Iraq. In addition to this narrative and comparison of the best medication used to treat this pandemic, we also surveyed the opinions of over 100 people on the medicines discussed in this study throughout their treatment. The medicinal properties of medications used for COVID-19 and the results of their use on humans were studied in this review to promote appropriate medications for the treatment of coronavirus.

ABSTRACT

Diagnostic testing is important for managing the 2019 novel coronavirus (SARS-CoV-2). We developed an optimized protocol for SARS-CoV-2 RNA extraction from the surface of the respiratory mucosa with nasopharyngeal swabs and compared the sensitivity of RNA extraction methods. RNA extraction was performed using three different procedures (TRIzol, QIAamp, VMT-TRIzol) from nine positive SARS-CoV-2 samples. SARS-CoV-2 was detected by real-time reverse transcriptase PCR (RT-PCR) using a detection kit for SARS-CoV-2 (Sun Yat-sen University). Compared to RT-PCR results, there were no discernible differences in detection rates when comparing the three different extraction procedures. On the basis of these results, the use of TRIzol as a transport medium and RNA extraction method for SARS-CoV-2 detection may be a helpful alternative for laboratories facing shortages of commercial testing kits.
