Inception of COVID ’19 has brought new normal globally. Contagious nature of various infectious diseases necessitated frequent hand washing in order to reduce rate of contamination and community transmission. The need to contain the spread of COVID-19 necessitated the development of an Automatic Hand Sanitizing System (AHSS). The AHSS employed proximity sensor (IR) to sense the hand and actuate the 5V DC submersible pumps in charge of both water and sanitizer units of the AHSS. The DC voltage that powered the system was harvested from the Sun with the help of 5v Photovoltaic cell connected to a controlled charging circuit. The system responded to presence of user object within the active zone of the IR proximity sensors. This presence sends signal to the pumps to release either the Sanitizer/water. Evaluation based on Delay Time (DT), Average DT (ADT), True Positive (TP), False Positive (FP), Unable to Detect (UTD) and Accuracy (A) was conducted. The system was tested 180 times among students of School of Engineering, Federal Polytechnic, Ile-Oluji (FEDPOLEL). Results of evaluation indicate 12s, 180, 0.00, 0.00 and 100% for ADT, TP, FP, UTD and Accuracy, respectively. Accuracy of the designed AHSS was encouraging. An AHSS that can notify user about level of water and sanitizer, also test for presence of COVID-19 infection can also be designed and constructed.

Approximately forty-four percent of the global population lives in villages, including 59% in Africa ( https://unhabitat.org/World%20Cities%20Report%202020 ). The fast-evolving nature of SARS-CoV-2 and its extremely contagious nature warrant early and accurate COVID-19 diagnostics across rural and urban population as a key to prevent viral transmission. Unfortunately, lack of adequate infrastructure, including the availability of biosafety-compliant facilities and an end-to-end cold chain availability for COVID-19 molecular diagnosis, limits the accessibility of testing in these countries.

Nuclear rivalry, as well as terrorism and the war against terror, exemplify the dangerous escalation of violence that is threatening our world. Gandhi’s militant nonviolence offers a possible alternative that avoids a complacent indifference toward injustice as well as the imitation of violence that leads to its escalation. The French-American cultural anthropologist René Girard discovered mimetic rivalries as one of the main roots of human conflicts, and also highlighted the contagious nature of violence. This article shows that Gandhi shares these basic insights of Girard’s anthropology, which increases the plausibility of his plea for nonviolence. Reading Gandhi with Girard also complements Girard’s mimetic theory by offering an active practice of nonviolence as a response to violent threats, and by broadening the scope of its religious outreach. Gandhi’s reading of the Sermon on Mount not only renounces violence and retaliation like Girard but also underlines the need to actively break with evil. Both Gandhi and Girard also address the religious preconditions of nonviolent action by underlining the need to prefer godly over worldly pursuits, and to overcome the fear of death by God’s grace. This congruence shows that Girard’s anthropology is valid beyond its usual affinity with Judaism and Christianity.

BACKGROUND & OBJECTIVE: This study investigated medical and non-medical students’ knowledge, attitude, and preparedness regarding COVID-19 pandemic, to groom volunteers and future healthcare providers in a better way. METHODOLOGY: This cross-sectional study was completed from April to May 2020 during the first wave of COVID-19. An online questionnaire was distributed using internet and social media (SM). The questionnaire was composed of several parts concerning to demographic data, knowledge, attitude, and practices. RESULTS: This study included 1851 students [1041(56.54% medical, 810(43.46%) non-medical students)]. Medical students had significantly better knowledge about the contagious nature, spread and treatment of coronavirus. Non-medical students showed more risky behavior compared to medical students (p = 0.005). The use of masks and the frequency of handwashing was better among medical students as compared to non-medical students (p< 0.001; p< 0.014, respectively). The odds ratio indicates that students of the age group 21-25 years (45%) and medical students (75%) were more likely to have a positive attitude. CONCLUSION: This study revealed good knowledge, positive attitudes, and good practices towards COVID-19 among medical students. Still, a minority of participants from both groups revealed misconceptions and relatively poor conceptual knowledge regarding the disease.

The highly contagious nature of SARS-CoV-2 has led to several studies on the transmission of the virus. A little studied potential fomite of great concern in the community is currency, which has been shown to harbor microbial pathogens in several studies. Since the onset of the COVID-19 pandemic, many businesses in the United States have limited the use of banknotes in favor of credit cards. However, SARS-CoV-2 has shown greater stability on plastic in several studies.  Herein, the stability of SARS-CoV-2 at room temperature on banknotes, money cards and coins was investigated. In vitro studies with live virus suggested SARS-CoV-2 was highly unstable on banknotes, showing an initial rapid reduction in viable virus and no viral detection by 24 hours. In contrast, SARS-CoV-2 was far more stable on money cards with live virus detected after 48 hours. Environmental swabbing of currency and money cards on and near the campus of Brigham Young University supported these results, with no detection of SARS-CoV-2 RNA on banknotes, and a low level on money cards. No viable virus was detected on either. These preliminary results suggest that the use of money cards over banknotes in order to slow the spread of this virus may be ill-advised. These findings should be investigated further through larger environmental studies involving more locations.

Abstract Background Forgotten or retained (double-J) DJ stents may lead to several complications. Management of retained DJ stents poses a challenge for urologists not just surgically but also medicolegally and adds to the economic burden of the patient. Difficulty in follow-up for patients due to the contagious nature of COVID-19 and several restrictions posed in the form of lockdown. Smartphones today have become an integral part of our daily lives providing a convenient and reliable platform for data storage and access. Methods All patients requiring placement of DJ stents and agreeing to enrol in the study were registered on the application over the physicians smartphone. SMSs regarding dates for removal of stent and follow-up with the literature regarding stent care were sent to the patients in their regional language. Results A total of 100 patients were stented during this period of 3 months. Mean age was 42.61 years with three patients of paediatric age group. Mean duration of stent was 6 weeks. All patients received periodic messages (average 3) regarding follow-up and date for stent removal. 3%(n = 3) patients were delayed for follow-up; 2% (n = 2) patients lost to follow-up, compared to a 9% to 10% loss to follow-up in patients followed up only on paper discharges in our department previously. Conclusion It significantly reduced the number of physical visits of the patient to the hospital and provided a more streamlined tracking of the indwelling stents for the user; patient compliance was found to be almost 98%; being cloud based (android/iOS), it was easily accessible to the user; and with the option of sharing the account details, the patient record could be accessed by several residents from their individual devices, which significantly reduced loss to follow-up rates from 9 to 2%.

The COVID-19 outbreak in 2020 has changed the way people travel due to its highly contagious nature. In this study, changes in the travel behavior of passengers due to COVID-19 in the first half of 2020 were examined. To determine whether COVID-19 has affected the use of transportation by passengers, paired t-tests were conducted between the passenger volume of private vehicles in Seoul prior to and after the pandemic. Additionally, the passenger occupancy rate of different modes of transportation during the similar time periods were compared and analyzed to identify the changes in monthly usage rate for each mode. In the case of private vehicles and public bicycles, the usage rates have recovered or increased when compared to those of before the pandemic. Conversely, bus and rail passenger service rates have decreased from the previous year before the pandemic. Furthermore, it is found that existing bus and rail users have switched to the private auto mode due to COVID-19. Based on the results, traffic patterns of travelers after the outbreak and implications responding to the pandemic are discussed.

Correctly recognizing and efficiently attending to emotional situations are highly valuable skills for social species such as humans and bonobos, humans' closest living relatives. In the current study, we investigated whether humans perceive a range of emotional situations differently when these involved other humans compared to bonobos. A large group of children and adults participated in an emotion perception task and rated scenes showing either bonobos or humans in situations depicting distressed or aggressive behavior, yawning, scratching, grooming, playing, sex scenes or neutral situations. A new group of people performed a dot-probe task to assess attentional biases toward these materials. The main finding is that humans perceive emotional scenes showing people similarly as emotional scenes of bonobos, a result reflecting a shared evolutionary origin of emotional expressions. Other results show that children interpreted bonobos’ bared teeth displays as a positive signal. This signal is related to the human smile, but is frequently seen in distressed situations, as was the case in the current experiment. Children may still need to learn to use contextual cues when judging an ambiguous expression as positive or negative. Further, the sex scenes were rated very positively, especially by male participants. Even though they rated these more positively than women, their attention was captured similarly, surpassing all other emotion categories. Finally, humans’ attention was captured more by human yawns than by bonobo yawns, which may be related to the highly contagious nature of yawns, especially when shown by close others. The current research adds to earlier work showing morphological, behavioral and genetic parallels between humans and bonobos by showing that their emotional expressions have a common origin too.
