ABSTRACT
Objective. To examine the relationship between eHealth literacy, perceived risk, and COVID-19 phobia among Chinese university students studying in Korea (the international group) and China mainland (the mainland group). Methods. A cross-sectional survey was conducted using an online questionnaire. With 1,107 student samples, structural equation modeling (SEM) was performed to examine the relationship between eHealth, perceived risk, and COVID-19 phobia among the two groups. Results. These Chinese university students had a COVID-19-related eHealth literacy of 30.23 (SD 6.65), with scores of the mainland group higher than those of the international group. The international group students (56.47 +/- 17.64) reported a higher level of COVID-19 phobia than the mainland group students (48.89 +/- 17.76). The findings indicated that use frequency and information trust were higher when students possessed a higher level of COVID-19 eHealth literacy. Information trust would not have a significantly positive relationship with COVID-19 phobia, while higher levels of information use and perceived risk were positively associated with COVID-19 phobia. Conclusion. eHealth literacy, information factors, and perceived risk were associated with Chinese university students' phobia status. There may be substantial feasibility and practicality in conducting relevant interventions that consider the university students' psychological status and risk perception based on eHealth literacy and information factors.
ABSTRACT
In face of the complex and severe epidemic prevention and control situation and extremely arduous tasks of drug review, from 2020 to 2021, under the strong leadership of National Medical Products Administration (NMPA) Leading Party Members' Group, Center for Drug Evaluation (CDE) of NMPA exerted all its strength to promote the emergency review and approval of COVID-19 vaccines and drugs and continue to deepen the reform of the review and approval system, with gradually appearing benefits of reform;CDE also continued to promote the reform of the traditional Chinese medicine (TCM) evaluation mechanism and carry out the transformation of achievements in three anti-epidemic prescriptions;multiple measures were implemented to support pediatric drugs research and development and innovation. New progress was made by modernization of the evaluation system and capacity, a more complete evaluation standard and a more scientific process-oriented evaluation system were established, which continuously enhanced the people's sense of happiness and security.

ABSTRACT
The outbreak of COVID-19 has encouraged people to wear their masks more frequently than ever. However, the absence of much facial information from the masked face will cause failures in many current face recognition and verification functions to recognize the individual's identity. To tackle this problem precisely, our group builds a modified SimCLR model with the contrastive loss that is able to extract similarity features from individuals regardless of whether a mask is worn. From our experiments, we find out that our usage of contrastive loss leads to a large improvement in the testing verification accuracy compared to a baseline model with the commonly used MSE loss. © 2021 IEEE.
ABSTRACT
BackgroundThe residents of Victoria (Australia’s second most populous state), were subject to a hard lockdown for several months as they experienced a second wave of COVID-19. Victorians could only leave their homes for essential activities, were required to wear facemasks, remain within 5km of their homes and were subject to a nightly curfew. Elsewhere in Australia, COVID numbers remained low with no lockdown in place. We examined the impact of the lockdown on the sexual behaviour of Victorians compared with elsewhere in Australia.MethodsOur online survey was open for 2.5 weeks during the lockdown (August 13th to 31st). Participants aged 18+ were recruited via social media and asked to report on their current sexual practices. Logistic regression was used to calculate the difference in the proportion of practices between Victorians and non-Victorians.Results976 people completed the survey: 71% identified as female, 75% were aged 18–29 years, 61% resided in Victoria. Compared with elsewhere in Australia, Victorians were less likely to report sex in the last 4 weeks (54.8% vs 68.0%, diff=-13.3%, 95%CI -19.6, -6.9). Victorians were also less likely to report casual hook-ups (10.6% vs 17.3%;diff=-6.7%, 95%CI -12.5, -0.8) and sex with a fuckbuddy (10.6% vs 16.9%;diff=-6.2%, 95%CI-12.1,-0.4). There was no difference in dating app use in the last 4 weeks between Victorians and others (27.0% vs 26.6%;diff=0.4;95%CI -5.2,6.1), but Victorians were more likely to report using apps for virtual dates (15.7% vs 2.9%, diff=12.8%, 95%CI 6.2,19.3) and chatting (83.0% vs 72.5%;diff=10.5;95%CI 0.0,20.9) and less likely to use them for face-to-face dates (15.1% vs 56.9%;diff=-41.8%, 95%CI -52.9,-30.7).ConclusionsHard lockdowns impact sexual behaviour and practices. However, sexual activity did not stop completely, highlighting the importance of ensuring accessibility of sexual and reproductive health services during periods of restriction.
ABSTRACT
To investigate the knowledge, preventive practices, and depression of Chinese university students living in South Korea and Mainland China during the COVID-19 outbreak and explore the determinants of depression among these students, an online cross-sectional questionnaire survey was conducted from 23 March to 12 April 2020. The online questionnaire included questions on knowledge and preventive practices related to COVID-19, and the Patient Health Questionnaire-9 was used to diagnose depressive symptoms. A total of 420 Chinese university students were finally included in the study (171 students from South Korea and 249 students from Mainland China). The majority of these students had a good level of knowledge of COVID-19. Students living in South Korea displayed better preventive practices than those living in Mainland China;however, the proportion of students (28.7%) with moderate-to-severe depression in this group was relatively higher than that (18.9%) of the Mainland Group (chi<sup>2</sup> = 5.50, p < 0.05). More severe depression was related to high levels of concern about family members and contracting COVID-19 as well as suspecting themselves of having come into contact with patients. Displaying more preventive behaviors decreased the depressive symptoms in both groups. These data could be used as a reference for further studies in different regions to take measures (e.g., psychological counseling and encouragement for physical activities) to reduce depressive symptoms in university students.
