Cheating Prevention in E-proctoring Systems Using Secure Exam Browsers: A Case Study

In this research, a case study has been conducted to analyze the possibility of preventing cheating or reducing it by using one of the lockdown browsers during the exam. An e-exam has been created using Moodle platform, and the exam has been conducted with the Safe Exam Browser (SEB) as a restriction program at one time and without it at another time, and an analysis has been made of the extent of the possibility of cheating during the exam for both cases. Wireshark and Registry Changes View programs have been used to observe the possibility of opening programs and applications or the ability of the examinee to use Windows tools during the exam. The use of Wireshark and Registry Changes View software showed high effectiveness in analyzing the examinee's device data and identifying the examinee's activity during the electronic exam, to give a clear perception of the possibility of preventing access to resources and applications on the examinee's device. The researchers concluded that the use of lockdown browsers is very necessary to prevent the examinee from accessing the resources on his device, which leads to a significant reduction in cheating during the electronic exam. The research contributions are two, the first one is the use of analyzing programs to observe the examinee`s activity during the exam, and the second one is presenting the lockdown browsers` features

Determination of time-dependent coefficient in time fractional heat equation

The aim of this work is to determine the time-dependent heat coefficient in a type of inverse problem for one dimensional time-fractional heat equations defined by the Caputo operator for (0<α<1) by applying a method based on the finite difference scheme and Tikhonov’s regularization. First, a stable implicit finite difference scheme is applied to find a numerical solution to the (forward) direct problem. While the inverse problem was reformulated as a nonlinear least-square minimization problem with a simple physical bound on the unknown coefficient and solved efficiently by MATLAB routine lsqnonlinfrom the optimization toolbox. But the latter problem will remain ill-posed because the presence of any error in the input data will lead to a large error in the output data. So, Tikhonov’s technique is applied to obtain stable results. In the end, two numerical test examples show that the proposed method is stable, accurate, and works well with different noise level

Healthy Behavior to Athletes among Physical Impairment Sport Clubs in Jordan

The study aimed to identify the patterns of healthy behavior which common among physical disabled athletes in Jordanian sport clubs, and the differences in the level of healthy behavior according to the variables: the club, the game, sex, age, and level of education. The sample of this study included (101) Players from Jordanian sport clubs for physical disabled athletes. The sample of this study was chosen randomly. Then, the researcher designed a questionnaire to identify the patterns of healthy behavior. The questionnaire distributed into four axises: (73) items were about personal healthy behaviors which related to training or competition, (18) items were about risky behaviors (smoking, alcohol, steroids, stimulants, narcotics), (24) items were about food and feeding habits, (13) items were about positive healthy behaviors. The data of this study are analyzed by using descriptive statistics (mean, standard deviation, and rank) for each variable of the study variables, T- Test, ANOVA (analysis variance) followed by a comparable dimensional test as well as the significance and coefficient of Cronbach\u27s alpha. The results indicated that the response of the sample to measure health behavior characterized normally and propensity toward moderation, as the similarity of healthy behavior among members of the same research due to the variables (educational qualification, age, sex, type of game which practiced) in general and the partial effect of the sex factors in the fields of risky behaviors and clubs that belong to players between the clubs (the future and Alwafa) and (Alwafa and national) in the field of risky behaviors

Possible acute rejection associated with the use of the new antihepatitis C virus medications

Hepatitis C virus infection is associated with increased morbidity and mortality. It remains a major challenge for management and treatment, especially in patients with renal transplant. The new directacting antiviral agents gave big hopes to both clinicians and patients that they can overcome this challenge without major side effects. Studies recently have supported this claim; however, they are still few, limited, and may give false hopes. In the following case report, we present a case, supported by histological evidence about a possible acute rejection of kidney transplant after treatment with these new medications. This case is limited by the absence of donorspecific antibodies. This report is aimed to increase awareness about the urgent need for further studies

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

Background Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population.The aim of this study was to inform vaccination prioritization by modelling the impact of vaccination on elective inpatient surgery. The study found that patients aged at least 70 years needing elective surgery should be prioritized alongside other high-risk groups during early vaccination programmes. Once vaccines are rolled out to younger populations, prioritizing surgical patients is advantageous
