The Impact of Covid-19 Pandemic on Students’ Sport Activity

The rapid spread of COVID-19 virus in Romania has had a substantial impact on higher education, where almost all institutions have been closed and on-site teaching activities have been replaced by online courses (at the peak of the pan-demic, 90% of the world’s students were affected by the closure of institutions). International research papers show that these prevention measures have in-creased stress and anxiety levels and the number of cases of depression. This fact had a considerable effect especially among the students of the physical education faculties, who could no longer support their sports activities. As shown in the pre-sent study, 80.5% of the students confirmed that they were affected physically and mental/emotional by the COVID-19 pandemic. The research aimed to identify the current physical condition, but also to compare the physical condition before and during the pandemic and to understand the emerging negative effects of the pan-demic on students of the Faculty of Physical Education and Sports at Babes-Bolyai University in Cluj-Napoca.

A Global Study of the Wellbeing of Adolescent Students During the COVID-19 2020 Lockdown

AbstractAs the COVID-19 (SARS-CoV-2) virus spread across the world, countries took drastic measures to counter the disease by requiring their citizens to home self-isolate i.e., lockdown. While it was not known how young people would cope with the social distancing restrictions, there was concern that the lockdown would have a debilitating effect on youth mental health. This study examined whether there was an association between adolescent subjective wellbeing and the amount of time spent in lockdown. Global Research Alliance researchers in 15 countries collected data using the Mental Health Continuum (Keyes in Am J Orthopsych 76:395–402, 2006) from over 7000 middle-school students aged 11–18. Findings show a decline in eudemonic wellbeing, particularly among females during the first 6 months of lockdown, which was most strongly associated with diminished psychological wellbeing, followed by social wellbeing, while emotional wellbeing remained relatively stable. An adaptation effect was noted after approximately 6 months. There was evidence suggesting females were slower to adapt to lockdown conditions compared to males. More attention should be paid to the wellbeing of students in lockdown to overcome languishing tendencies and educators should be cognizant of diminished student wellbeing, particularly among females, when students return to school. Positive school experiences, and positive relationships within the school community, may assist in reducing the risk of languishing in lockdown conditions, so schools should design interactive online activities for off-campus learning.

Study on SEAI Model of COVID-19 Based on Asymptomatic Infection

In this paper, an SEAI epidemic model with asymptomatic infection is studied under the background of mass transmission of COVID-19. First, we use the next-generation matrix method to obtain the basic reproductive number R0 and calculate the equilibrium point. Secondly, when R0<1, the local asymptotic stability of the disease-free equilibrium is proved by Hurwitz criterion, and the global asymptotic stability of the disease-free equilibrium is proved by constructing the Lyapunov function. When R0>1, the system has a unique endemic equilibrium point and is locally asymptotically stable, and it is also proved that the system is uniformly persistent. Then, the application of optimal control theory is carried out, and the expression of the optimal control solution is obtained. Finally, in order to verify the correctness of the theory, the stability of the equilibrium point is numerically simulated and the sensitivity of the parameters of R0 is analyzed. We also simulated the comparison of the number of asymptomatic infected people and symptomatic infected people before and after adopting the optimal control strategy. This shows that the infection of asymptomatic people cannot be underestimated in the spread of COVID-19 virus, and an isolation strategy should be adopted to control the spread speed of the disease.

Iran’s Legislative Policy in dealing with Fraud During COVID-19 Pandemic

The fear of the coronavirus has led to various types of scams related to the virus on the internet and in people’s homes, including in Iran. Scams include fraud through corona vaccine cards, fake coronavirus tests, counterfeit drugs, phishing fraud, and sites selling masks at exorbitant prices. Criminals have also been visiting homes for corona testing or disinfection, and using the pretext of livelihood loans or pre-sale advertisements of tourist tours with corona vaccine injections. As the COVID-19 virus spreads, Iran’s legislative policy has been to punish criminals to maintain the psychological safety of society. However, implementing legal principles in emergencies like this can be challenging, especially when ensuring the right to health and compliance with the basic human rights of criminals or their rehabilitation is necessary. Therefore, criminal policymakers should identify technological punishments and penal policies that are suitable for emergencies. They should create suitable grounds for achieving the goals of criminal justice in these circumstances. This article uses the descriptive-analytical method to explain Iran’s legal criminal policy towards criminals in the coronavirus era. It examines the principles of human rights and criminal principles that lead to appropriate legislative policies in upcoming events like COVID-19. The paper concludes that Iran’s legislative policy in emergencies like Corona is severe punishment of criminals to maintain the psychological safety of society. However, it also seeks to rehabilitate the criminals.

Pengaruh Reka Bentuk Bangunan terhadap Sistem Pengudaraan Pusat Membeli Belah di Malaysia

The COVID-19 pandemic that hits the world since 2019, has become an eye-opener regarding the importance of having good ventilation system in buildings. An enclosed space which has a poor ventilation system causes the spread of COVID-19 virus more widely. Shopping malls are among the buildings that are often visited by the public. Therefore, this study is conducted out of awareness of the need to use an effective ventilation system in shopping mall, especially since the COVID-19 pandemic occurs. This study is a preliminary study. The objective of this study is to identify the influence of building design on the ventilation system used in shopping malls in Malaysia, from the past to the present. The research method used is qualitative descriptive evaluation through the observation and case studies. A total of four shopping malls around the Klang Valley, Malaysia, which are built in four different phases, have been selected for this preliminary study. The results show that shopping malls built before the year 2000, have enclosed type design, and the ventilation system used depends merely on a mechanical system which is air-conditioning system. Meanwhile, after the year 2000, the design of shopping mall has evolved to a combination of enclosed and open design. This design has affected the ventilation system used, which is a hybid system that combines the mechanical and natural ventilation. The results of this study are important in providing information about the approach to the ventilation system of shopping malls in Malaysia, from the past to the present. The results of this study are able to encourage various further studies regarding the ventilation systems in shopping malls.

Investigating the association of physical and psychological problems with the levels of interleukin-1 and -6 in COVID-19 patients.

The COVID-19 virus spreads at a high rate, exerting many physical, mental and psychological effects on patients. Patients with COVID-19 have been reported to have high levels of interleukin 1 and interleukin 6. Therefore, this study was conducted to determine the association of physical, mental, and psychological problems with the levels of interleukin-1 and -6 in COVID-19 patients. This is cross-sectional descriptive-analytical research on 121 COVID-19 patients selected using simple random sampling method. The patients were hospitalized in university hospitals affiliated to Ahvaz Jundishapur University of Medical Sciences and Amir al-Momenin Hospital. Data collection tools included the depression anxiety stress scale (DASS), a demographic questionnaire, and a checklist of physical problems. Blood sampling was also done to perform an ELISA test and measure the level of interleukin-1 and -6. Data were analyzed based on independent t-tests, chi-square, regression, and Pearson's correlation coefficient, using SPSS ver. 22. The average age of the 121 patients participating in this study was 53.31 ± 14.09. A direct and statistically significant correlation was observed between body temperature on the first day and interleukin 1 level. A statistically significant negative correlation was observed between blood oxygen saturation level and interleukin-1 and -6 on the first, third and fifth days. Shortness of breath and coughing had a statistically significant correlation with the level of interleukin 1 on the third and fifth days. A direct and statistically significant correlation was observed between body temperature on the first, third and fifth days and interleukin 6 level. Coughing on the third and fifth days had a statistically significant relationship with interleukin 6 level. No direct and non-significant statistical correlation was found between depression and stress and the serum level of interleukin 1, but a significant correlation was observed between anxiety and serum level of interleukin 1. Finally, the results showed that depression, anxiety and stress had a direct and statistically significant correlation with the serum level of interleukin 6. Given the relationship between interleukin-1 and -6 and most physical and psychological problems, level of the inflammatory biomarkers interleukin-1 and -6 can be used to estimate the severity of physical and psychological symptoms in COVID-19 patients.

Research on the Distribution of Emergency Supplies during the COVID-19 Epidemic

The COVID-19 virus spreads quickly and is highly contagious, and the timeliness of emergency supplies is extremely demanding, so adequate and efficient emergency supplies have become a necessary prerequisite for strict prevention and control during the outbreak. However, the available research results are still relatively few, and using the brain storm optimization algorithm to solve the emergency supplies distribution problem is still blank. In order to optimize the emergency supplies distribution system in the context of COVID-19, this paper studies the open vehicle routing problem by considering the load weight constraints, demand constraints, and time window constraints. With the shortest total distribution distance as the objective function, a mathematical model of mixed integer linear programming is established, and the crossover operation of the genetic algorithm, the destruction operator and the repair operator of the large neighborhood search algorithm are introduced in the brain storm optimization algorithm to enhance the diversity of the solution while making the solution toward the optimal direction. Through the verification of two sets of examples, we found that compared with the other 13 solution algorithms, the solution capability and solution efficiency of the brain storm optimization algorithm are better than the comparison algorithms, which can significantly reduce the length of the distribution route and lower the distribution cost, and has excellent convergence and stability. Meanwhile, it can effectively improve the distribution efficiency of emergency supplies, which is of great significance to help the emergency reception and regular prevention and control during the outbreak of the COVID-19 epidemic. In addition, it has the necessary guidance for the improvement of personnel efficiency in the supply chain and logistics industry.
