Perception of Hurricane and COVID-19 Risks for Household Evacuation and Shelter Intentions

The COVID-19 pandemic presented new challenges for scholars and government officials to predict people's evacuation decisions under a conflicting natural disaster. In this study, we examined households' evacuation and shelter intentions given the potential conflicts between the perceived risks from a hurricane and the coexisting public health crisis. We surveyed households living inside hurricane evacuation zones in Florida during the 2020 hurricane season. Data were first used to examine the evacuation and shelter intentions before and during the pandemic. We then measured respondents' hurricane and COVID-19 risk perception, respectively. The impacts of both risk perceptions on respondents' hurricane evacuation intentions were explored. We found that when people felt unsafe to stay home for a Category 2, 3, or 4 hurricane, their intended evacuation was about the same before and during the pandemic regardless of their COVID-19 risk perception. The COVID-19 risk perception, however, significantly lowered the evacuation intention for a Category 1 hurricane. It also significantly influenced evacuees' preference for nontraditional shelters such as government-contracted hotels. The results of our study have practical implications for emergency management and public health governance. Our study also provides insights into decision-making under the conflict between natural hazards and infectious diseases. (English) [ FROM AUTHOR] La pandemia del COVID-19 planteó nuevos retos a los eruditos y funcionarios gubernamentales para predecir las decisiones de evacuación de la gente sometida a un desastre natural conflictivo. En este estudio, examinamos la evacuación e intenciones de albergue de familias teniendo en cuenta potenciales conflictos entre los riesgos percibidos de un huracán y las crisis coexistentes en la salud pública. Encuestamos a las familias que residían en las zonas de evacuación por huracanes de la Florida durante la temporada de huracanes del 2020. Los datos se usaron primero para examinar las intenciones de evacuación y de refugio antes y durante la pandemia. Después, medimos la percepción del riesgo de afectaciones por huracanes y COVID-19 de los encuestados, respectivamente. Se exploraron los impactos de ambos tipos de percepciones de riesgo en las intenciones de evacuación, por encuestado. Hallamos que cuando la gente se siente insegura de permanecer en casa frente a huracanes de las categorías 2, 3 y 4, su evacuación intencionada era más o menos la misma de antes y durante la pandemia, sin importar la percepción del riesgo de COVID-19. No obstante, la percepción del riesgo de COVID-19 redujo de manera significativa la evaluación de la intención de evacuación para un huracán de categoría 1. Eso también influyó significativamente en la preferencia de los evacuados por refugios no tradicionales, como los hoteles contratados por el gobierno. Los resultados de nuestro estudio tienen implicaciones prácticas en el manejo de las emergencias y la gobernanza de la salud pública. También proporciona nuestro estudio nuevas visiones en lo que concierne a toma de decisiones bajo condiciones de conflicto entre las catástrofes naturales y la enfermedades contagiosas.

Control System for Indoor Safety Measures Using a Faster R-CNN Architecture

This paper presents a control system for indoor safety measures using a Faster R-CNN (Region-based Convolutional Neural Network) architecture. The proposed system aims to ensure the safety of occupants in indoor environments by detecting and recognizing potential safety hazards in real time, such as capacity control, social distancing, or mask use. Using deep learning techniques, the system detects these situations to be controlled, notifying the person in charge of the company if any of these are violated. The proposed system was tested in a real teaching environment at Rey Juan Carlos University, using Raspberry Pi 4 as a hardware platform together with an Intel Neural Stick board and a pair of PiCamera RGB (Red Green Blue) cameras to capture images of the environment and a Faster R-CNN architecture to detect and classify objects within the images. To evaluate the performance of the system, a dataset of indoor images was collected and annotated for object detection and classification. The system was trained using this dataset, and its performance was evaluated based on precision, recall, and F1 score. The results show that the proposed system achieved a high level of accuracy in detecting and classifying potential safety hazards in indoor environments. The proposed system includes an efficiently implemented software infrastructure to be launched on a low-cost hardware platform, which is affordable for any company, regardless of size or revenue, and it has the potential to be integrated into existing safety systems in indoor environments such as hospitals, warehouses, and factories, to provide real-time monitoring and alerts for safety hazards. Future work will focus on enhancing the system's robustness and scalability to larger indoor environments with more complex safety hazards.

Governing systemic and cascading disaster risk in Indonesia: where do we stand and future outlook

PurposeThis paper aims to identify key factors for a contextualised Systemic Risk Governance (SRG) framework and subsequently explore how systemic risks can be managed and how local institutional mechanisms can be tweaked to deal with the complex Indonesian risk landscape.Design/methodology/approachUsing a case study from Palu triple-disasters in Central Sulawesi, Indonesia, the authors demonstrate how inland earthquakes in 2018 created cascading secondary hazards, namely tsunamis, liquefactions and landslides, caused unprecedented disasters for the communities and the nation. A qualitative analysis was conducted using the data collected through a long-term observation since 2002.FindingsThe authors argue that Indonesia has yet to incorporate an SRG approach in its responses to the Palu triple-disasters. Political will is required to adopt more appropriate risk governance modes that promote the systemic risk paradigm. Change needs to occur incrementally through hybrid governance arrangements ranging from formal/informal methods to self- and horizontal and vertical modes of governance deemed more realistic and feasible. The authors recommend that this be done by focusing on productive transition and local transformation.Originality/valueThere is growing awareness and recognition of the importance of systemic and cascading risks in disaster risk studies. However, there are still gaps between research, policy and practice. The current progress of disaster risk governance is not sufficient to achieve the Sendai Framework for Disaster Risk Reduction (2015–2030) unless there is an effective governing system in place at the local level that allow actors and institutions to simultaneously manage the interplays of multi-hazards, multi-temporal, multi-dimensions of vulnerabilities and residual risks. This paper contributes to these knowledge gaps.

Effects of the COVID-19 pandemic on the mental health of hotel housekeeping staff. (Special Issue: Tourism in the northeast.)

This research aimed to understand the effects of the Covid-19 pandemic on the mental health of workers of hotel housekeeping departments in the city of Joao Pessoa/PB. A quantitative analysis was carried out, to measure the information gathered from workers of three medium-sized hotels in the capital of the state of Paraiba, using a questionnaire to gather data, and descriptive analysis for the data analysis. It was found that the Covid-19 pandemic had caused impacts on the mental health of workers in this area, mainly in terms of financial worries;fear of losing their jobs;fear of contracting the disease while at work;and fear that if infected, they might pass it on to other members of the family. Added to this were physical fatigue, obsession with cleaning, and stress.

Surface deformation and damage of 2022 (M 6.8) Luding earthquake in China and its tectonic implications

The 2022 (M 6.8) Luding earthquake on the Xianshuihe Fault Zone (XFZ) caused severe casualties and property losses, and surface deformation and damage of which is crucial for studying the earthquake hazard assessment. However, few intensive scientific understanding has obtained to date because of widespread coronavirus transmission, strong vegetation coverage, and post-earthquake paralyzed traffic. By integrating high-resolution satellite images, large-scale geomorphic mapping, and UAV surveys, we constrain coseismic fractures and ruptures along an NW-SE-trending surface deformation zone, with discontinuous geomorphic scarps, en echelon cracks, and bulges concentrated in the areas of Yanzigou, Moxi, Menghugang, and Xingfu villages near the epicenter. Field observation also shows that the zone extends nearly parallel to the pre-existing XFZ with a length of ∼35 km with variable widths and a maximum vertical displacement of ∼100 ± 10 cm. The earthquake-induced surface coseismic effects, such as landslides, rock falls, and collapses, caused damage to the area. The amplification effect of the topography and the improper aseismic design and poor constructions may be responsible for the spatial distribution of MM Intensity IX, which is larger than other previous earthquakes that occurred in the surrounding area with a similar tectonic setting.

Seroprevalence of anti-SARS-CoV-2 antibodies in high-risk occupational and low-risk groups in southwestern Iran

Background: Monitoring the spread of SARS-CoV-2 has been considered by the World Health Organization (WHO). We examined the prevalence of anti-SARS-CoV-2 immunoglobulin antibodies in southwestern Iran in spring 2020. The circulation of SARS-CoV-2 is high in the general population, especially among health care workers (HCWs) who are in close contact with patients. Objectives: The aim of this study was to determine the prevalence of anti-SARS-CoV-2 antigen in high-risk occupational and low-risk groups to investigate risk factors for serum positivity in Shiraz, southwestern Iran. Methods: A cross-sectional survey was performed on 366 participants (204 from high-risk and 162 from low-risk subjects). IgG and IgM antibodies were detected using Pishtaz Teb COVID-19 ELISA Kits to evaluate SARS-CoV-2-antigen in serum samples. After enzyme-linked immunosorbent assay (ELISA), serum prevalence, as well as IgG/IgM positive factors, was determined using logistic regression. Results: From July to September 2020 (a few months after reporting the first case of COVID-19 cases in Iran), out of 366 survived people, 72 (40.9%) were IgG positive, and 50 (27.5%) were IgM positive. The frequency of positive serology for IgG and IgM antibodies in individuals aged < 30 years was higher in the low-risk group than in the high-risk group. Multivariate logistic regression showed that headache (OR 0.312 [95% CI: 0.136 - 0.717]) and cough (OR 0.427 [95% CI: 0.182 - 1.004]) factors were associated with IgG or IgM positive serology. Conclusions: Between July and September 2020, the prevalence of anti-SARS-CoV-2 antigen was high in Shiraz. The prevalence of SARS-CoV-2 IgG/IgM antibodies in the high-risk group and their family as low risk was shown to increase viral infection due to close contact with COVID 19 patients than in the general population. Several factors were found to be related to the prevalence of anti-SARS-CoV-2 antigen that needs to be considered by policymakers to determine what to do about the SARS-CoV-2 pandemic.

Health in the Skies: A Narrative Review of the Issues Faced by Commercial Airline Pilots.

While the health of airline pilots is crucial to ensuring the safe travel of millions of people worldwide, they remain vulnerable to a variety of health challenges due to the nature of their job. The purpose of this narrative review is to provide a comprehensive summary of the most common health issues experienced by commercial airline pilots. By examining the published literature on this topic, we sought to identify areas where further research is needed to understand better the health risks associated with being a pilot and to develop effective interventions to address these risks. We also highlight how recent technological advances in digital health can be leveraged to conduct research into the potential usefulness of telehealth assessments for identifying occupational hazards in the aviation sector and providing targeted interventions. Overall, addressing the challenges of taking care of pilots' health and ensuring public safety will require a collaborative effort among airlines, governments, and regulators. Prioritizing pilot health and safety can actually improve profitability in the aviation sector by reducing costs associated with absenteeism, turnover, and accidents.

Americans' COVID-19 risk perceptions and risk perception predictors changed over time

Identifying and understanding risk perceptions—"how bad are the harms” to humans or to what they value that people see as potentially or actually arising from entities or events—has been critical for risk analysis, both for its own sake, and for expected associations between risk perceptions and subsequent outcomes, such as risky or protective behavior, or support for hazard management policies. Cross-sectional surveys have been the dominant method for identifying and understanding risk perceptions, yielding valuable data. However, cross-sectional surveys are unable to probe the dynamics of risk perceptions over time, which is critical to do while living in a dynamically hazardous world and to build causal understandings. Building upon earlier longitudinal panel studies of Americans' Ebola and Zika risk perceptions using multi-level modeling to assess temporal changes in these views and inter-individual factors affecting them, we examined patterns in Americans' COVID-19 risk perceptions in six waves across 14 months. The findings suggest that, in general, risk perceptions increased from February 2020 to April 2021, but with varying trends across different risk perception measures (personal, collective, affective, affect, severity, and duration). Factors in baseline risk perceptions (Wave 1) and inter-individual differences across waves differed even more: baseline ratings were associated with how immediate the threat is (temporal distance) and how likely the threat would affect people like oneself (social distance), and following the United States news about the pandemic. Inter-individual trend differences were shaped most by temporal distance, whether local coronavirus infections were accelerating their upward trend, and subjective knowledge about viral transmission. Associations of subjective knowledge and risk trend with risk perceptions could change signs (e.g. from positive to negative) over time. These findings hold theoretical implications for risk perception dynamics and taxonomies, and research design implications for studying risk perception dynamics and their comparison across hazards. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

Visual analysis of the trend of mental health changes among Chinese college students in the context of the normalisation of the new crown epidemic

Public health events are sudden, public in nature and have serious social hazards. The COVID-19 outbreak coincided with the Lunar New Year, which had a direct or indirect impact on all areas of society. Previous studies related to emergencies have found that a considerable number of college students lacked experience in dealing with emergencies, were not emotionally stable enough, lacked analysis and decision-making ability, were easily suggestible and acted more impulsively. Therefore, in this paper, based on the existing actual information, combined with the awareness and understanding of college students' mental health, and based on the existing research results, the Hopfield-mental health model is used as a theoretical basis to study the trend of changes in college students' mental health. The results of the study show that 83.21% of the people are more concerned about the situation of this new crown pneumonia epidemic and they think that the new crown epidemic has seriously affected their living habits;65.45% thought that this new crown pneumonia epidemic did not have any major impact on their school life. The five sources of psychological stress, including academic, employment, economic, interpersonal relationship and love, were calculated and analysed in the model, which showed that employment stress, academic stress and economic stress were the largest sources of psychological stress among college students in this new pneumonia epidemic, accounting for 89%, 81% and 93%, respectively. They were followed by interpersonal and romantic stress, with 31% and 52%, respectively. © 2022 Liping Zhang.

COVID-19 exposure setting, social and gender determinants in a Mediterranean region

BACKGROUND: Knowledge of social and gender determinants, which influence the places where people are exposed to COVID-19, may be relevant in the development of preventive and control strategies. The aim of this paper was to determine the context in which COVID-19 cases were infected (household, work/labor, health, social-health, and social-leisure settings) according to country of origin, occupational social class and gender, which is essential in order to designing public health strategies. METHODS: A cross-sectional study of an epidemiological registry of 56,628 COVID-19 incident cases was made, whose exposure/ contagion setting was studied according to the previous variables from June 15 to December 23, 2020, in the Region of Murcia (Spain). An exact Fisher test was used to study the distribution of COVID-19 cases based on the above variables. RESULTS: The cumulative incidence was higher in people from Africa (5,133.5 cases/100,000 inhabitants) and Latin America (11,351.1) than in non-immigrants (3,145.7). It was also higher in women (3,885.6) than in men (3,572.6). It is noteworthy, that 53.3% of the cases with employment were workers in industry or construction, artisans, agricultural workers, or elementary occupations. In contrast, during the second semester of 2020, 41.3% of the employed population in the Region of Murcia performed such jobs. The household was the main exposure setting (56.5% of cases with a known setting), followed by social-leisure (20.7%) and work/labor (18.2%). The labor settings were more important in immigrants from Africa (28.4%) and Latin America (35.7%) than in non-immigrants (12%), inversely to social-leisure settings. Labor context was more important in women (19.6%) than in men (16.5%) and in manual workers (44.1%) than in non-manual workers (26.6%). CONCLUSIONS: The context in which COVID-19 cases were infected is different according to social inequalities related to country of origin, gender and occupational social class.

Chemical Safety Knowledge Assessment of Academic Researchers from Brazil During Covid-19 Pandemic

Introduction: Laboratories are inextricably dangerous work environ-ments, as fatal incidents are reported in both academic and non-aca-demic environments worldwide, where poor safety culture has been rec-ognized as the major accident contributor. Workers can be exposed to chemical, biological, physical, or radioactive hazards, in addition to mus-culoskeletal stresses. In Brazil, hundreds of thousands of workers are employed in laboratories, either in private or public institutions. Alt-hough laboratory safety can be governed by local, state, or federal regu-lations, learning how to identify common laboratory hazards is the first step to preventing accidents in the lab environment. Methods: The study aimed to assess the degree level of safety culture in an academic population of research laboratories, located in the largest city in Brazil, and their compliance with occupational safety regulations during the COVID-19 outbreak. This study was carried out between Oc-tober and November 2020. The results were obtained from the standard-ized questionnaire used to assess 98 researchers working in laboratories during the COVID-19 pandemic. Results: The majority of respondents (95%) reported being exposed to more than two risks, simultaneously. About two-thirds (66%) of them were not fully aware of the laboratory's risk map. About half of the re-searchers (50%) were lacking in safety culture, and 57%and 43% were preoccupied with chemical and non-chemical hazards, respectively. Per-sonal protective equipment (PPE) during laboratory work was used by most researchers, but 75% of researchers claim that security awareness learning should be a high priority for admission to laboratories. About 39% of researchers agreed that awareness of security must be improved in their laboratories Conclusion: The survey proves the lack of information and attitudes about chemical safety, especially among less experienced researchers, even if they use personal protective equipment when necessary. © 2023 by Animal Bioscience.

Air pollution with pm10 for the municipality of Burgas and the monthly cases of disease with COVID 19, 2021

An important environmental problem for the Municipality of Burgas is the relatively high levels of PM10 pollution. Particulate matter PM10 is defined as the fraction of particles with an aerodynamic diameter smaller than 10 pm. The article provides statistical processing and evaluation of daily data on the concentration of PM10 in the air by quarters fix Burgas, 2021. A histogram of the frequency distribution of concentrations by quarters was prepared. A regression model for calculating the monthly concentrations in the atmospheric air is derived The tests and inspections performed show that the performed modelling is suitable for evaluation, analysis and forecast. Air pollution harms human health and the environment. Exposure ID air pollution is associated with a wide range of acute and chronic health effects, ranging from irritating effects to death From the end of 2019 until now in the world, Europe and in particular Bulgaria is raging a dangerous respiratory disease known as COVD19. The average monthly new cases of COVD19 for Burgas were assessed, as well as the respective maximum and minimum monthly values. A qualitative assessment of the relationship between the monthly concentrations of PM10 and the incidence of COVID19 was made.

Need of Technological Interventions for Indoor Air Quality and Risk Assessment Upon Short-Term Exposure: A Futuristic Approach

The variation in ambient air pollution hampers indoor air quality (IAQ), and even the short-term variation is very hazardous for the exposed population. Technological interventions including sensors, smartphones and other gadgets are implemented to build smart environments. However, these interventions are still not fully explored in developing countries like India. The COVID-19 pandemic has made it very important to keep a tab on the air we breathe in as those already suffering from respiratory troubles are prone to fall victim to the deadly disease. In such a scenario, even a rise in pollution for a short duration is dangerous to the exposed pollution. Such short-term exposure facilitated by the meteorological creates a disaster for environmental health. The short-term rise in the concentration of pollutants makes things worse for the exposed people, even indoors. It is therefore critical to come up with a concrete solution to predict the IAQ instantly and warn the exposed population which can be only achieved by technological interventions and futuristic Internet of Things-based computational predictions. This chapter is intended to elaborate the health hazards linked to short-term rise in pollutants, which often goes unnoticed but has a critical impact and how with the help of IoT-based applications, the short-term variation can be predicted through different strategies. Similarly, the assessment of the health impact associated with short-term exposure to air pollution is also significant, and different exposure assessment models and computational strategies are discussed in the course of the study. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Ambulatory visits, active component, U.S. Armed Forces, 2021

The aggregate numbers and rates of ambulatory care visits by active component service members in 2021 were the highest of the previous ten years. Most disease and injury categories experienced slight increases in both rates and numbers. From 19% of ambulatory care visits in 2020 to less than 15% in 2021, telehealth contacts were used less frequently. The statistics for 2021 demonstrate a return to pre-pandemic levels, notwithstanding the possibility that the response to the COVID-19 pandemic in 2020 was related with declines in the incidence of disease and injury diagnoses in the community of service members seeking ambulatory care. Additionally, the proportions of telehealth-delivered medical encounters have similarly decreased to the lower levels seen before the pandemic. Lessons learned may direct future actions to lower the frequency of disease and harm in the post-pandemic era. This study details the ambulatory health care visits made by active component members of the U.S. Army, Navy, Air Force, and Marine Corps in 2020 in terms of frequency, rates, trends, and other factors. U.S. service members' ambulatory visits to fixed military and nonmilitary medical treatment facilities (reimbursed through the Military Health System [MHS]) are recorded in standardized, computerized records. The Defense Medical Surveillance System (DMSS), the data source for this report, routinely archives these records for health surveillance purposes. This research excludes ambulatory visits that are not frequently and fully recorded using standardized electronic records (for example, during deployments, field training exercises, or at sea). As in previous MSMR reports, the primary (first-listed) diagnostic position of the visit records was used to categorize all records of ambulatory visits of active component service members according to the first four characters of the ICD-10 codes. In this research, a specific query of the DMSS records was carried out to identify ambulatory visits that were completed via "telehealth" encounters rather than in-person meetings (e.g., via telephone or video conferencing). Most data summaries included both types of encounters and did not make a distinction between them, however due to the rise in telehealth encounter usage during the coronavirus 2019 (COVID-19) pandemic, changes in the proportions of telehealth encounters were examined.

Technostress at work during the COVID-19 lockdown phase (2020-2021): a systematic review of the literature.

Technostress is a psychosocial phenomenon associated with the use of technologies to the detriment of health, the same one that during the pandemic was accelerated in the work considering home confinement. This work aims to systematize the main research on the impact of technostress at work during the severe confinement stage of the pandemic, between the years 2020 and 2021, with the purpose of identify and evaluate its main determining factors. A systematic review of the literature was carried out during COVID-19, using the words "technostress work COVID-19." The works found focus mainly on analyzing the creators and inhibitors of technostress in workers, as well as the main consequences of the materialization of this technological risk associated with work performance during the stage of confinement by COVID-19. Techno invasion and techno overload were identified as the main techno stressors, with the main type of technostress appreciated in the literature being techno fatigue. Technostress is identified as a problem that had direct and relevant effects during the season of severe confinement and remote work at home due to COVID-19; highlighting techno fatigue as the most frequent type of stress, and techno stressors such as techno invasion and overload as the ones that presented the highest incidence.

Bioprotection of Transportation and Facilities from SARS-CoV-2 (COVID-19).

The recent COVID-19 pandemic has led to a nearly world-wide shelter-in-place strategy. This raises several natural concerns about the safe relaxing of current restrictions. This article focuses on the design and operation of heating ventilation and air conditioning (HVAC) systems in the context of transportation. Do HVAC systems have a role in limiting viral spread? During shelter-in-place, can the HVAC system in a dwelling or a vehicle help limit spread of the virus? After the shelter-in-place strategy ends, can typical workplace and transportation HVAC systems limit spread of the virus? This article directly addresses these and other questions. In addition, it also summarizes simplifying assumptions needed to make meaningful predictions. This article derives new results using transform methods first given in Ginsberg and Bui. These new results describe viral spread through an HVAC system and estimate the aggregate dose of virus inhaled by an uninfected building or vehicle occupant when an infected occupant is present within the same building or vehicle. Central to these results is the derivation of a quantity called the "protection factor"-a term-of-art borrowed from the design of gas masks. Older results that rely on numerical approximations to these differential equations have long been lab validated. This article gives the exact solutions in fixed infrastructure for the first time. These solutions, therefore, retain the same lab validation of the older methods of approximation. Further, these exact solutions yield valuable insights into HVAC systems used in transportation.
