Deploying the Minimum Number of Rechargeable UAVs for a Quarantine Barrier

To control the rapid spread of COVID-19, we consider deploying a set of Unmanned Aerial Vehicles (UAVs) to form a quarantine barrier such that anyone crossing the barrier can be detected. We use a charging pile to recharge UAVs. The problem is scheduling UAVs to cover the barrier, and, for any scheduling strategy, estimating theminimum number of UAVs needed to cover the barrier forever. We propose breaking the barrier into subsegments so that each subsegment can be monitored by a single UAV. We then analyze two scheduling strategies, where the first one is simple to implement and the second one requires fewer UAVs. The first strategy divides UAVs into groups with each group covering a subsegment. For this strategy, we derive a closed-form formula for the minimum number of UAVs. In the case of insufficient UAVs, we give a recursive function to compute the exact coverage time and give a dynamic-programming algorithm to allocate UAVs to subsegments to maximize the overall coverage time. The second strategy schedules all UAVs dynamically. We prove a lower and an upper bound on the minimum number of UAVs. We implement a prototype system to verify the proposed coverage model and perform simulations to investigate the performance.

A retrospective study of knowledge management for integrated resorts (IRs) crisis preparedness

PurposeThis study aims to propose a systematic knowledge management model to explore the causal links leading to the organizational crisis preparedness (OCP) level of integrated resorts (IRs) during the COVID-19 pandemic based on the intangible capital of organizational climate, dynamic capability, substantive capability and commitment.Design/methodology/approachThe authors use data obtained from IRs in Macau. The Wuli–Shili–Renli (WSR) approach underpins the study. Structural equation modeling following fuzzy-set qualitative comparative analysis (fsQCA) was used for data processing.FindingsThe results showed that organizational climate has an essential role in IRs preparedness for crises and affects their dynamic capacity, substantive capacity and commitment. The fsQCA results revealed that the relationships between conditions with a higher level of dynamic and substantive capability lead to higher OCP scores.Practical implicationsExecutives should develop systemic thinking regarding organization preparedness in IRs for crisis management. A comprehensive understanding of the IRs' business environment and crises is necessary, as they will require different factor constellations to allow the organization to perform well in a crisis. Financial support for employees could ensure their assistance when dealing with such situations. Rapid response teams should be set up for daily operations and marketing implementation of each level of the IRs management systems.Originality/valueThis study contributes to the extant literature on IRs crisis management in the OCP aspect. The authors constructed a systematic composite picture of organization executives' knowledge management through the three layers of intangible capitals in WSR. Moreover, the authors explored causal links of WSR from symmetric and asymmetric perspectives.

Social media use, psychological well-being and physical health during lockdown

In efforts to curb the spread of COVID-19, many countries have implemented a variety of lockdown and quarantine measures. With substantially reduced face-to-face interactions, many people may have relied heavily on social media for connection, information, and entertainment. However, little is known about the psychological and physical health implications of social media use during strict lockdown. The current study investigates the associations of social media use with psychological well-being and physical health among Wuhan residents (N = 1214). Our findings showed that non-COVID related self-disclosure was positively associated with psychological well-being, while COVID related information consumption and sharing were negatively associated with psychological well-being. Further, more generic use of social media was associated with lower psychological well-being, which in turn related to more somatic symptoms. Quarantined people used social media more frequently than non-quarantined people. Importantly, the negative association between social media use and psychological well-being was significantly stronger for quarantined people than unquarantined people.

Mental disorders during the pandemic of a new coronavirus infection: causes and predisposing factors.

Objective: to study the causes and predictors of mental disorders during the COVID-19 epidemic in those who turned to psychiatrist for the first time, as well as in patients with already diagnosed mental illness. Patients and methods. We examined 100 patients who turned to a psychiatrist due to a deterioration in their mental state during the pandemic, 50 patients were newly diagnosed (Group 1) and 50 with previously diagnosed mental disorders (Group 2). The study was carried out by a clinical method using a specially designed map, followed by statistical processing of the obtained data. Results and discussion. Mental disorders caused by the COVID-19 pandemic more often occurred at a young age, in patients with higher and secondary specialized education, and in single patients. In the 1st group, as a result of exposure to psychogenic factors (the influence of the media, quarantine, economic changes), anxiety (36.8%) and depressive (21.1%) disorders occurred more often, and after the coronavirus infection, depressive disorders were in the first place (54.2%). The 2nd group mostly included patients with endogenous disorders (bipolar affective disorder - 24%, recurrent depressive disorder - 20%, schizophrenia - 20%), which were exacerbated more often as a result of COVID-19, to a lesser extent - psychogenic (experiences associated with a change in material status and illness of relatives). Obsessive-compulsive disorder, generalized anxiety disorder, somatoform disorders have been associated with epidemic factors. Conclusion. The results obtained indicate that there are differences between the mental disorders that first appeared during the pandemic and the exacerbations of the condition in mentally ill patients, which relate to the predictors, causes and clinical manifestations of these disorders.Copyright © 2022 Ima-Press Publishing House.

University students' experience with mobile learning during COVID-19 pandemic

The study focuses on mobile learning at universities, with emphasis on the changes brought by the quarantine during the COVID-19 pandemic (the first and the second wave) in which only distance education was possible. The participant sample consisted of Slovak university students (N = 48;age 20–25 in 2020 and N = 45;age 20–25 in 2021). Qualitative design and narrative method were chosen to find out the individuals' experience of concrete events embedded in a socio-cultural context. The data was analyzed using a holistic-content perspective in combination with a thematic analysis. The results showed the key moments linked to the university students' experience in the first wave of the COVID-19 pandemic: nostalgia, shock – sudden change, and adaptation. In the second wave of the COVID-19 pandemic, the key moments were: nostalgia, uncertainty, and short-term planning. The important phases for the sustainability of m-learning were related to the comparison between nostalgia, the recovery from the shock after a sudden change in lifestyle, and the adaptation to new living conditions. This was reflected in the key topics focused on the main phases, with an accent on life enjoyment, self-centring, and stress before the COVID-19 pandemic. The paper fulfills the gap in the research focused on understanding students' feelings, attitudes, values, and use of m-learning during forced distance education. Qualitative design research allowed going deeper into students" psychological aspects during national quarantine. The results allow us to prepare the universities and state policies on working with students during future crises and emphasize sustainable mobile learning.

COVID-19 pandemic and comfort food consumption based on gender in a Brazilian sample: which variables are related to this behavior?

PurposeThis study aims to identify comfort food (CF) consumption and its associated factors during the pandemic period. The study also involves an online survey conducted five months after the quarantine started in Brazil. Design/methodology/approachData on lifestyle, eating habits and anthropometric data were collected before and during the pandemic, and the differences in these habits were analyzed. Univariate and multivariate logistic regression models were performed to identify predictors of CF consumption by gender. FindingsA total of 1,363 individuals were included in the sample, with a median age of 31 years old, of whom 80.3% were women. Since individuals were free to respond about the food consumed without predetermined categories, it was possible to carry out a faithful assessment of the occurrence of this behavior. At the same time, allowing the subjectivity and symbolism inherent to the concept of CF to be embraced. CF consumption was present for 54%, with "sweets" being the most mentioned group by both genders. The factors associated with CF consumption in women during the pandemic were increased snacking, increased bread, candies and alcoholic beverage intake, increased time spent at work, worsened sleep quality, reduced meals, perceived stress (PS), emotional eating (EE), age and increased frequency of meat intake. In men, the predictors for CF consumption were remote full-time work/study, PS, EE and early waking time. For both genders, CF consumption during the pandemic period was associated with PS and EE. Originality/valueThis study provides an important overview of the possible contributions of the pandemic on behaviors and food choices related to the consumption of CF in Brazilians. This information is valuable to support further studies to investigate and treat the impacts of the pandemic on lifestyle, eating habits and behavior, mental health and other factors in the postpandemic period.

Alcohol risk consumption during the COVID-19 pandemic quarantine time in Paraguay, 2020: a virtual survey

Introduction: The impact of the outbreak of pandemic proportions of COVID-19 has initiated several health and social measures worldwide. Thus, there is growing concern about the consequences of preventive social confinement associated with the pandemic due to the potential increase in the consumption of alcohol and other harmful substances. Between 2010-2014, in Paraguay approximately 5% of deaths over 15 years of age are attributable to alcohol consumption and are associated with external cause injuries, cancers, liver disease, cardiovascular diseases, addictions and domestic violence. Early detection and treatment are recommended intervention strategies to prevent these consequences. Objective: To determine the demographic characteristics of alcohol risk consumption during the covid-19 pandemic quarantine period. Methods: Analytical cross-sectional, exploratory observational study. It consisted of 16,538 virtual surveys carried out on persons of legal age throughout the national territory between June and September 2020. A total of 219 respondents were excluded for not meeting the inclusion criteria or for incorrectly filled out data. Risk consumption was determined using a test that rated consumption by scores. More than 5 points for men, more than 4 for women. Results: 12224 adult participants (18-65 years old) with a mean age of 31.9 years (±9.2), were part of the analysis, with a predominance of male participation 64.5% (n=10531). The 74.9% (n=12224) came from the Metropolitan Axis. According to gender, the OR was 1.15 CI95 (1.08-1.23), pv=0.001. When comparing educational level, high school complete/incomplete, the OR was 1.56 CI95 (1.19-2.06), pv=0.001. And when comparing by axes of residence, the OR was 0.83 CI95 (0.77-0.89), pv=0.001. Discussion: It was observed that, during the quarantine period, alcohol consumption increased as the educational level of the population increased. Males presented a higher risk consumption than males. Knowing this behavior would help to propose actions to help prevent alcohol consumption in the most atrisk group. © 2022, Faculty of Medical Sciences, Santa Rosa del Aguaray Branch, National University of Asuncion.

A Review on the Effect of COVID-19 in Pregnant Women

Coronavirus Disease 2019 (COVID-19) is an emerging disease with a rapid increase in cases and deaths since its first discovery in December 2019, in Wuhan, China. Limited data are available on COVID-19 effects during pregnancy;however, information on diseases associated with other highly pathogenic coronaviruses (i.e. Severe Acute Respiratory Syndrome [SARS] and the Middle East respiratory syndrome [MERS]) may provide insight into the effects of COVID-19 during pregnancy. Coronaviruses cause illnesses ranging from the common cold to severe respiratory disease and death. The data indicate an average of 5 days incubation period (range: 2-14 days). The average age range of the hospitalized patients was 49-56 years, and a third to half of them have an underlying illness. Children were rarely mentioned. Within hospitalized cases, men were more frequent (54%-73%). Fever, cough, myalgia, vomiting, and diarrhea are common symptoms. This review aims at giving an in-depth understanding of COVID-19 by comparing its effects with SARS and MERS to evaluate its severity in pregnant women1. The results of varied studies show that COVID-19 affects pregnant women seriously and there is an alarming need to look into this aspect to prevent its harmful effects on the fetus.Copyright © 2020

Viral modernity? Epidemics, infodemics, and the ‘bioinformational' paradigm

Viral modernity is a concept based upon the nature of viruses, the ancient and critical role they play in evolution and culture, and the basic application to understanding the role of information and forms of bioinformation in the social world. The concept draws a close association between viral biology on the one hand, and information science on the other – it is an illustration and prime example of bioinformationalism that brings together two of the most powerful forces that now drive cultural evolution. The concept of viral modernity applies to viral technologies, codes and ecosystems in information, publishing, education and emerging knowledge (journal) systems. This paper traces the relationship between epidemics, quarantine, and public health management and outlines elements of viral-digital philosophy (VDP) based on the fusion of living and technological systems. We discuss Covid-19 as a ‘bioinformationalist' response that represents historically unprecedented level of sharing information from the sequencing of the genome to testing for a vaccination. Finally, we look at the US response to Covid-19 through the lens of infodemics and post-truth. The paper is followed by three open reviews, which further refine its conclusions as they relate to (educational) philosophy and the notion of the virus as Pharmakon.

Traffic Impacts of the COVID-19 Pandemic: Statewide Analysis of Social Separation and Activity Restriction

The COVID-19 pandemic resulted in significant social and economic impacts throughout the world. In addition to the health consequences, the impacts on travel behavior have also been sudden and wide ranging. This study describes the drastic changes in human behavior using the analysis of highway volume data as a representation of personal activity and interaction. Same-day traffic volumes for 2019 and 2020 across Florida were analyzed to identify spatial and temporal changes in behavior resulting from the disease or fear of it and statewide directives to limit person-to-person interaction. Compared to similar days in 2019, overall statewide traffic volume dropped by 47.5%. Although decreases were evident across the state, there were also differences between rural and urban areas and between highways and arterials both in terms of the timing and extent. The data and analyses help to demonstrate the early impacts of the pandemic and may be useful for operational and strategic planning of recovery efforts and for dealing with future pandemics.

Television coverage of gender-based violence in Spain during lockdown

This article analyzes the presence of gender-based violence on free-to-air Spanish television (TV) channels La1, Antena 3, Tele 5, La Sexta, and Cuatro throughout their 24-h daily broadcasting, between March 20, 2020 and June 20, 2020, along with the same period for the year 2019. This article studies whether, despite the COVID-19-dominated agenda of media coverage of gender-based violence increased or decreased, driven by government policies to protect potential victims. Also, we analyze whether any TV channels provided tools (such as the 016 helpline) to help women or were rather limited to reporting murder cases. In addition, the most predominant terms used in such coverage are identified, along with any potential difference in the behavior of public versus private TV channels. The data confirm, among other issues, that coverage of gender-based violence on these TV channels decreased during the studied time frame. However, the mention of tools aimed at supporting women at risk increased. The results of this study also reveal that TV coverage of violence against women did not coincide with the dates in which gender-based murders took place and that, of all Spanish media networks, public TV paid the most attention to this issue.

Areas within the United States at the Highest Risk for African Swine Fever, Classical Swine Fever, and Foot-and-Mouth Disease Introduction

Domestic livestock production is a major component of the agricultural sector, contributing to food security and human health and nutrition and serving as the economic livelihood for millions worldwide. The impact of disease on global systems and processes cannot be understated, as illustrated by the effects of the COVID-19 global pandemic through economic and social system shocks and food system disruptions. This study outlines a method to identify the most likely sites of introduction into the United States for three of the most concerning foreign animal diseases: African swine fever (ASF), classical swine fever (CSF), and foot-and-mouth disease (FMD). We first created an index measuring the amount of potentially contaminated meat products entering the regions of interest using the most recently available Agricultural Quarantine Inspection Monitoring (AQIM) air passenger inspection dataset, the AQIM USPS/foreign mail, and the targeted USPS/foreign mail interception datasets. The risk of introduction of a given virus was then estimated using this index, as well as the density of operations of the livestock species and the likelihood of infected material contaminating the local herds. Using the most recently available version of the datasets, the most likely places of introduction for ASF and CSF were identified to be in central Florida, while FMD was estimated to have been most likely introduced to swine in western California and to cattle in northeastern Texas. The method illustrated in this study is important as it may provide insights on risk and can be used to guide surveillance activities and optimize the use of limited resources to combat the establishment of these diseases in the U.S.

Changes in the characteristic of dietary and lifestyle during Covid-19 lockdown in different countries: A systematic review

Due to the covid-19 pandemic, governments were forced to adopt lockdown policies to effectively control the pandemic. These restrictions increased anxiety, depression, and lifestyle changes. This systematic review aims to analyze changes in dietary patterns in the worldwide population during the COVID-19 lockdown. 11 studies were selected from the 1412 founds after searching in three databases. Searching keywords were: "Change dietary”, "COVID-19 dietary” "Confinement dietary”. Inclusion criteria were: studies that collected people's dietary patterns during the COVID-19 lockdown and recorded the consumption of food groups and the variations in lifestyle habits. This research found that people increased their consumption of food. People increased their sedentary hours, slept more but exercised less, leading to gain weight during the lockdown, as well as a poorer sleeping quality and higher anxiety levels.Alternate : Debido a la pandemia de COVID-19, los gobiernos se vieron obligados a tomar medidas de confinamiento para controlar eficazmente el contagio. Sin embargo, después de un tiempo de control al poblado, estas restricciones hicieron la gente tener más ansiedad y depresión, incluso cambiar el estilo de vida.

Potential targets and traditional Chinese medicine treatment strategy of cough after SARS-CoV-2 infection.

The severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) Omicron variants BA.5.2 and BF.7 have become the main epidemic strains in China since the quarantine policy was lifted in 7th December 2022. Cough is one of the main symptoms induced by SARS-CoV-2 infection. SARS-CoV-2 infection-associated cough injuries the lung and upper respiratory tract, while the infected people cough out virus and liquid which forms virus-containing aerosols, a medium for quickly spreading. Furthermore, cough is one of primary sequelae of discharged patients in corona virus disease 2019 (COVID-19). By now, there are no efficacious drugs for treatment of upper respiratory tract infection associated cough induced by omicron. Traditional Chinese medicine (TCM) has a long history on treating cough. By reviewing the mechanisms of the occurrence of cough after SARS-CoV-2 infection, potential therapeutic targets and cough suppressant herbs with significant efficacy in clinical and basic research, we provide a reference for the treatment of cough after SARS-Cov-2 infection and a basis for the majority of infected patients to select appropriate herbs for cough relief under guidance of physicians.Copyright © 2023 Editorial Office of Chinese Traditional and Herbal Drugs.

Intentions of companies for health-promoting telework after the COVID-19 lockdown 2020

Background: Companies had to find quick solutions for continuing to work due to the pandemic in spring 2020. However, working conditions at home (teleworking) do not always comply with the basic principles and quality criteria of workplace health promotion (WHP). Objectives: How strongly is the approach of health-promoting telework (working at home) established in companies and what influences the strategic anchoring and the use of supporting materials? Materials and methods: Theoretically derived hypotheses were operationalised and 1858 Austrian companies were invited to participate in an online survey. The sample (n = 192) represents a broad mix of company sizes, sectors and regions. Results: Workplaces vary widely in their intention to implement health-promoting telework in the future. A part can be explained by multivariate path models, with behavioural control and social norms playing a central role. The former is determined by the degree of preparation for telework and its implementation in the company. In particular, teleworking culture, in addition to teleworking readiness, is shown to be responsible for the strength of social norms towards its implementation. Conclusions: Teleworking has so far received too little attention in the sense of holistic WHP. Such an implementation strongly depends on the health-promoting corporate structures and processes, the culture, and the decision-makers' scope for action. Companies are recommended to follow the concept of capacity building in order to build up competencies and knowledge and to enable appropriate measures.

Home-based care programme (HBCP) for patients with COVID-19: Boon or burden during pandemic management?

Introduction and Aim: India experienced the peak of the second wave of COVID-19 during April to June 2021. Massive surge of cases resulting in shortage of beds and oxygen, home care was recommended as a strategy for management of asymptomatic/mild COVID-19 cases. The present study was undertaken to perform home visits and monitor COVID 19 patients who are a part of home-based care programme (HBCP) in Puttur taluk of Dakshina Kannada district, identification and immediate referral of patients with red flag signs/ symptoms and to identify barriers/challenges faced by health care staff in implementing the programme. Methodology: The present study was a cross-sectional study with universal sampling. It was carried out as part of a district programme for management of home isolation COVID-19 patients. The team visited the houses of COVID-19 patients and evaluated them. Result(s): A total of 112 COVID-19 patients were in home isolation during the study period in Puttur Taluk. Hypertension (29.5%) was the most common co-morbidity and nearly two-fifths (41.1%) of the study participants had one or more comorbidities. Almost two-third (63%) of the patients with comorbidities were symptomatic compared to only 29.4% of patients without any comorbidities. Of the six patients who had saturation of less than 95% five were more than 60 years of age, only one had received vaccination against COVID-19 and all had comorbidities. The HBCP had to face several challenges as the team members could not be in full PPE because of long distances between the houses and hard to reach areas. Conclusion(s): Overall, it is a helpful initiative for patients as the health services were provided at the doorstep during the time of restriction of movement. This can be an important tool in managing not only COVID pandemic but also future outbreaks that may follow.Copyright © 2023, Indian Association of Biomedical Scientists. All rights reserved.

The animal keeping culture and the motivation of animal keepers in Hungary

Background: In the past few decades the animal keeping culture and habits have changed a lot internationally, some animals have become family members. The COVID-19 pandemic has created an unprecedented situation in the world, including Hungary. In many places, the quarantine period was associated with Isolation and, therefore, an increase in the number of companion animals. Objectives: Our aims were to (1) survey the animal keeping culture and habits, (2) examine the motivation of the owners and (3) explore the attitudes about adoption, neutering, breeding and the use of livestock animals in Hungary. Materials and Methods: Specialized surveys were conducted among 843 persons through social media and personal interviews from 20 June to 30 August 2021 by using a questionnaire including 16 questions. The chosen groups were compared with Fisher's Exact test and Chi-square test. Results and Discussion: 97.0% of the respondents regard their dog as a family member. Nearly 25% of the respondents do not wish to neuter their dogs, because they want to breed the dogs or they find it unnecessary. The primary reason for cat keepers not to neuter their pet is the financial issue. Animal keepers and women are significantly more likely to consider their animal as a family member (p < 0.001). Men, the elderly, people who live in the countryside and those who have only elementary education think that neutering is of less importance (p < 0.001). Non-animal keepers, elderly people and men think more negatively about adoption. Buying an animal from a breeder is more important to the younger age groups (p < 0.001) arid those who live in Budapest (p < 0.01). 42.3% of the respondents gave the lowest evaluation scores to the assessment of the livestock units. Women, people from younger age groups (p < 0.05) and those who have higher education (p < 0.001) think more negatively about the use of farm animals. Non-animal keepers, the elderly and people of lower education consider the livestock animals' emotional intelligence lower (p < 0.05). Men (p < 0.001), people over 65 years of age (p < 0.001) and of lower education (p < 0:01), and also non-animal keepers (p < 0.001) accept significantly easier the use of livestock animals.
