ABSTRACT
Background: This study aims to evaluate the mental health status of children, adolescents and their parents during the first year of COVID-19 pandemic in Belgium. Method(s): Analysis compared results before and during the second national lockdown, which started on November 2nd 2020. A cross-sectional online survey was conducted between May 2020 and April 2021. Result(s): Two hundred and eighteen adults and 273 children fully completed the survey. Almost one in five children (17.9%) presented moderate-to-severe scores of depression. Adolescents presented a higher level of depression than children (p = 0.007). The rate of moderate-to-severe depression scores (10.8% to 21%, p = 0.007) and internalized symptoms increased during the second lockdown (p < 0.001). Parents' depression (p < 0.001) and anxiety (p = 0.027) levels also increased during the second lockdown. Logistic regression showed that the use of psychotropic medication in parents and parents' depression scores were risk factors for children to have worse depression scores. Conclusion(s): The second lockdown appears to worsen the effects of the pandemic on children's and parents' mental health. There is a need to implement specific interventions targeting both children/adolescents and their parents to support them during lockdown periods and improve mental health outcomes.Copyright © 2022, The Author(s).
ABSTRACT
Background and Objectives: Fear of COVID-19 is common among older adults and negatively impacts on their physical and mental health. Self-regulation is an essential factor for controlling or managing excitement and anxiety. So, this study aimed to determine the relationship between fear of COVID-19 and death anxiety with the moderator role of self-regulation among the elderly residing in Qazvin. Method(s): This descriptive and cross-sectional study was performed on 430 elderly aged 60 and over living in Qazvin in 2021. Samples were selected by cluster sampling method. The demographic checklist, Templer death anxiety scale, fear of COVID-19 questionnaire, and Self-Regulation Inventory were used for collecting the data. The data were analyzed using the Path Analyze test. Result(s): The mean age of the elder participants in the study was 66.88 +/- 6.40 years old. The results showed a significant and positive relationship between fear of COVID-19 and death anxiety (beta=0.60, P<0.001) and an inverse association between fear of COVID-19 (beta=-0.24, P=0.021) and death anxiety (beta=-0.10, P=0.021) with self-regulation. Furthermore, the results of the Path analysis confirmed the moderator role of self-regulation in the association between fear of Covid-19 and death anxiety among the elderly residing in Qazvin, Iran. Conclusion(s): Given the mediator role of self-regulation in the relationship between fear of COVID-19 and death anxiety, it is suggested to use teaching strategies to the older adults to improve self-regulation to control and mitigate the negative impacts of the fear of COVID-19 in this vulnerable population.Copyright © 2022 The Authors.
ABSTRACT
The aim of the research. To study the features of cardiovascular system disorders in post-covid syndrome (PCS) in children and adolescents after a mild form of coronavirus infection (COVID-19). Material and methods. From 260 children and adolescents after a mild form of COVID-19, a total of 30 patients aged 7-17 years with cardiac manifestations of PCS were selected. Therewith, 32 patients with an uncomplicated form of the disease were selected to form a comparison group. In 3 and 6 months after disease onset, a comprehensive examination of patients was performed with a questionnaire on the subjective scale for MFI-20 assessment asthenia (Multidimensional Fatigue Inventory-20), electrocardiography (ECG), echocardiography;daily monitoring of ECG and blood pressure. The biochemical blood test included assay of creatine phosphokinase-MB (CPK-MB), troponin I and lactate dehydrogenase (LDH). Results. The incidence of PCS with cardiac manifestations amounted to 11.5 %. After 3 months from the disease onset, complaints of pain and discomfort in the chest, palpitations, fatigue, and poor exercise tolerance persisted. Asthenic syndrome was diagnosed in 70 % of patients. The "general asthenia" indicator totalled14 [12;16] points (p<0.001) and was associated with the age of patients (r=+0.5;p<0.05). Arrhythmic syndrome and conduction disorders were detected in 67% of children. Labile arterial hypertension and hypotension occurred in 23 % of the adolescents. The increase in CPK-MB remained in 17% of the children, LDH - in 10%. In the sixth month after the onset of the disease, there were no significant differences in the results of the examination in the observation groups. However, a decrease in the level of resistance within 6 months was recorded in 43.3% of the schoolchildren with PCS (p<0.001). Conclusion. The data obtained indicate the need for early verification of cardiopathies in children with COVID-19, determination of a set of therapeutic and rehabilitation measures as well as ECG monitoring.Copyright © 2022, Krasnoyarsk State Medical University.

ABSTRACT
Background. Currently, a great body of data regarding the link between epilepsy and novel coronavirus infection (NCI) has been accumulated. Numerous studies have paid a great attention to rise in frequency and severity of epileptic seizures as well as failure of remission in individuals suffering from epilepsy. Objective(s): to study clinical and mental changes during NCI in patients with epilepsy. Material and methods. Fifty patients with epilepsy were examined, who were divided into two groups depending on the NCI history: Group 1 (main) - 25 patients undergone COVID-19 in the period from 2020 to 2022;Group 2 (control) - 25 patients not undergone COVID-19 during the same period. Slinical-anamnestic and psychometric methods were used as well as the following scales and questionnaires: National Hospital Seizure Severity Scale (NHS-3), Mini-Mental State Examination (MMSE), Hospital Anxiety and Depression Scale (HADS), Beck Depression Inventory (BDI), Medical Outcomes Study Sleep Scale (MOS-SS), Multidimensional Fatigue Inventory (MFI-20). Results. In patients with epilepsy who had undergone COVID-19, there was a tendency for more frequent epileptic seizures and increased severity of seizure course. Among such patients, mild depression and more severe asthenia, cognitive impairment, moderate sleep disturbances were more common than in the control group. Conclusion. The NCI pandemic has had a pronounced negative impact on the severity of epilepsy (the underlying disease).Copyright © 2023 IRBIS LLC. All Rights Reserved.
ABSTRACT
Although the importance and benefits of logistics integration in omni-channel (OC) retailing have been discussed in the literature, the impacts of logistics integration from the dimension of internal and external logistics remain unknown. To fill this gap, this study aims to investigate the relationships among internal and external logistics integration capabilities, supply-chain integration (SCI), and financial performance (FP) in OC retailing based on the dynamic capability view. An empirical study is conducted based on a survey of 230 OC retailers in China's market. Factor analysis and regression analysis are conducted to examine the hypotheses of the proposed conceptual model. The quantitative analyses show that the internal logistics integration capability is significantly related to the external logistics integration capability, and they both have positive effects on SCI, while the external logistics integration capability generates a higher impact (i.e., almost 1.5 times that of the internal logistics integration capability). The numerical results also demonstrate that the logistics integration capabilities and SCI have similar positive effects on FP (i.e., all the relevant regression coefficients show values around 0.25), and SCI plays a partial intermediary role in the relationships between logistics integration capabilities and FP. Furthermore, the quantitative evidence addresses the fact that the FP is not influenced by OC retailers' characteristics, indicating a fair business environment in the OC retail industry.
ABSTRACT
The sudden outbreak of the novel coronavirus (COVID-19) and the declaration of a pandemic caused many rapid changes to educational systems around the world in March 2020. Many issues were encountered during the transition from on-campus to online teaching and learning approaches. With educators and policymakers focusing on how best to provide quality education and scrambling to ensure that appropriate technology and teacher training were in place, mental health issues became increasingly prevalent. Positive education approaches that build on existing strengths are essential to ensure both student and teacher well-being. The Positive Workplace Framework (PWF) is an example of how a strength-based approach can improve well-being in schools. By implementing practices related to one's basic mental fitness needs and promoting team resiliency assets, schools can create optimal conditions that allow everyone to thrive and be at their best. The Mental Fitness and Resiliency Inventory (MFRI) is a validated questionnaire that provides a snapshot of a school's well-being practices, as well as a profile from which to structure plans for enhancing collective well-being among staff and students. © Springer Nature Switzerland AG 2021.

ABSTRACT
Background: The Covid-19 pandemic radically changed the way of studying, suddenly we went from fa-ce-to-face learning to a virtual one, in many cases without digital media, without properly managing plat-forms, adding anxiety to contagion, fear of death, economic instability, the uncertainty that it will happen, brings with it changes in academic work, thus influencing academic performance. Aim(s): Relate anxiety, self-esteem and study habits with academic performance in Peruvian university students. Methos: Quantitative, longitudinal, correlational and prospective study with a non-probabilistic sample of 260 students from the 1st cycle of the USS period 2020-II, virtual questionnaires were applied to measure anxiety (Beck's Anxiety Inventory), self-esteem (Stanley's Self-esteem Inventory Coopersmith), study habits (CASM-85 Study Habits Inventory) and academic performance (Promotional Proceedings). Result(s): 40% of the students present a minimum level of anxiety, 50.4% present high average self-esteem and 25.8% have very positive study habits. Conclusion(s): There is a relationship between anxiety and academic performance with statistical significan-ce;while self-esteem, study habits and academic performance were not statistically significant.Copyright © 2023, Ediciones Avances S.L..

ABSTRACT
Introduction: Burnout is common amongst clinical staff. Critical Care is widely accepted to have amongst the highest rates, with an incidence of >38%.1 The Covid-19 pandemic placed unprecedented pressures on staff, making them vulnerable to burnout.2 Although stressors were similar across medical teams, we suspected there were differences in burnout between medical specialties. Objective(s): This study aimed to examine burnout amongst the hospital MDT, focussing on three higher care clinical areas: Coronary Care (CCU), Respiratory (RSU) and Critical Care (ICU) and identify recurring positive and negative experiences. Method(s): Between March and April 2021 staff were invited to complete a two-part survey. Part one investigated demographic data and free text answers on feelings towards Covid-19. Part two questioned recipients on the 22 questions of the MBI -HSS (Maslach Burnout Index- Human Services Survey).3 This survey assesses burn-out in three domains: Emotional Exhaustion (EE), Depersonalisation (DP), and lack of Personal Accomplishment (PA). MBI-HSS results were analysed and a previously used 'high-risk' cut-off was used to calculate percentages per domain and overall. Free text analysis was conducted by two researchers to identify common themes, protective factors and negative factors which may increase burnout. Result(s): 148 staff members responded to the survey: 53% of respondents met the criteria for burnout in at least one domain. 58% of ICU staff, 42% of RSU staff and 44% of CCU staff were burnt out in one domain or more. ICU had the highest percentage of staff at high risk of EE and lack of PA. RSU had the highest percentage of staff scoring highly for DP. Free text analysis demonstrated some positive experiences from the Covid-19 pandemic: teamwork, communication, resilience, and opportunities to learn new skills were highlighted by staff across all areas. All areas found staffing and workload a negative factor. In ICU, workspace organisation and long shifts in PPE were key stressors which made communication and taking breaks safely difficult. Managing stress and uncertainty were highlighted by the ICU teams. In RSU, a significant proportion of staff found the lack of established treatments and poor outcomes difficult to manage, potentially highlighting the differences in Covid-19 management compared with ICU. As nursing staff work with higher ratios in RSU, some found managing patients' needs difficult: "Not having enough time to care for patients' basic needs . . . patients in side-rooms were left feeling isolated and scared". In CCU, there was a shift towards fear of catching the virus, PPE provision and poor infection control guidance, possibly arising from lower exposure to Covid-19: "It felt like the trust didn't give a s**t about their staff with regard to PPE and vaccinations." Conclusion(s): All clinical areas highlighted increased teamwork as a positive outcome of the Covid-19 pandemic, and good relationships have been built, a known protective factor against burnout. Many negative factors have impacted the rate of burnout, including high workload, staffing issues, redeployment and managing death and uncertainty. We hope to resurvey the same areas to assess wellbeing one year on, and address key factors to improve wellbeing.
ABSTRACT
PurposeThe purpose of this paper is to identify the radio frequency identification (RFID) strategic value attributes (RFIDSVAs) mechanism selections preferences and also integration of RFID tags with technology coordination tools (IRTWTCTs) alternatives ranking performance decisions in supply chain management (SCM). RFID-enabled techno-economic feasibility decisions are enhancing the SC visibility in apparel supply chains (ASCs). The RFIDSVAs mechanism selections have performed significant agility to strategic competitive advantages, namely, inventory visibility, multi-tags ownership transfer within trusted third party, etc.Design/methodology/approachFuzzy analytical hierarchy process (FAHP) and FAHP-fuzzy Technique for Order of Preference by Similarity to Ideal Solution (FTOPSIS) approaches have been used to evaluate the quantitative assessment of RFIDSVA mechanisms selection decision based on weight priority orders and IRTWTCTs alternatives selection in ASC networks. The comparison of FAHP and FAHP-FTOPSIS approaches to evaluate the integrated framework develop in RFIDSVAs mechanisms and IRTWTCTs alternatives selection decisions in Indian multi-tier ASC networks.FindingsThe result found that the FAHP-FTOPSIS approaches have used to prioritizing the RFIDSVA mechanism selection weights and also identify the IRTWTCTs alternatives ranking preferences order in apparel SCM. The comparison between the FAHP and FAHP-FTOPSIS approach to quantitative assessments from RFIDSVA mechanisms and IRTWTCTs alternatives selection decisions, which enable them SC agility potential across multi-tier visibility in ASC networks. ASC stakeholders can be benefited by techno-economic feasibility decisions, RFID-enabled shop floor activities, multi-tags ownerships transfer in SCs and knowledge-based cryptography tags/items separation in SCs.Research limitations/implicationsThe research work has considered only five RFIDSVA mechanisms and also three integration of RFIDTWTCTs alternatives in multi-tier ASC. The strategic competitive advantages are achieved by RFID-enabled break-even tags price decisions and also techno-economic feasibility decision by contractual design multi-tier SC stakeholder's involvements.Practical implicationsThe pilot project study explores that the quantitative assessment decision has based on RFID-enable techno-economic feasibility in ASCs. Stakeholders can be benefited by inventory control of the financial losses, reducing the inventory inaccuracies and multi-tags ownership transfer within trusted third-party traceability in ASC networks.Originality/valueThis study explores the RFID-enabled apparel SC process and activities visibility (natural fibre's fibre producer, fibre dyeing producer, yarn spinning producer, knitting and finishing producer).
ABSTRACT
In the context of the COVID-19 pandemic, the burden on healthcare professionals at all levels has increased significantly, especially those who are at the forefront of the fight for patients' lives. Physicians directly caring for COVID-19 patients are exposed to excessive stress and significant biological and psychosocial risk. Objective. To identify the features of the mental state of doctors of various specialties during the COVID-19 pandemic. Material and methods. The study included 85 doctors of the Arkhangelsk region: 41 anesthesiologists/intensive care physicians (mean age 32.4+/-5.0 years) and 44 general practitioners (mean age 38.9+/-4.2 years). The study was conducted during the third wave of the COVID-19 pandemic (from May to June 2021). We used the following study methods: questionnaire, psychological testing (K. Maslach and S. Jackson Burnout Inventory (MBI), Beck's Depression Inventory, Perceived Stress Scale, World Health Organisation-Five Well-Being Index), mathematical and statistical processing of empirical data. Results and discussion. Analysis of the results showed that about half of the surveyed general practitioners and only 3 (7.3%) of the anesthesiologists/intensive care physicians had a history of COVID-19, having contracted it while performing professional duties. Manifestations of maladaptation, such as low professional competence, lack of soft skills, aggressiveness, introversion, risktaking, recklessness, and family problems, are more pronounced in anesthesiologists/intensive care physicians. They were more likely to have negative emotions and feelings, were less satisfied with themselves and life in general, and had a lower well-being index than general practitioners. General practitioners overestimated their professional burnout severity and more often complained about their state of health. Correlation analysis of the examination results for anesthesiologists/intensive care physicians allowed us to identify direct relationships between the level of perceived stress, overstrain and depression, low mood, difficulties in relationships with relatives and colleagues, dissatisfaction with various aspects of life, inverse relationships between the level of perceived stress and the well-being index. In general practitioners, direct relationships were established between perceived stress and overexertion, and inverse relationships were established between the level of perceived stress, the well-being index, and the reduction of personal achievements. Conclusion. The COVID-19 pandemic negatively impacts anesthesiologists/intensive care physicians more than general practitioners, causing negative emotions and maladaptation. In primary care physicians, the pandemic increases mobilization processes to address emerging professional challenges. Therefore, special attention should be paid to psychological support for anesthesiologists/intensive care physicians.Copyright © 2023, Media Sphera Publishing Group. All rights reserved.
ABSTRACT
Background: The outbreak of the COVID-19 pandemic, the constant transformation of the SARS-COV-2 virus form, exposure to substantial psychosocial stress, environmental change, and isolation have led to the inference that the overall population's mental health could be affected, resulting in an increase in cases of psychosis. Objective(s): We initiated a systematic review to determine the impact of the SARS-COV-2 virus and its long-term effects-in both symptomatic and asymptomatic cases-on people with or without psychosis. We envisioned that this would give us an insight into effective clinical intervention methods for patients with psychosis during and after the pandemic. Method(s): We selected fifteen papers that met our inclusion criteria, i.e., those that considered participants with or without psychiatric illness and exposed to SARS-COV-2 infection, for this review and were retrieved via Google, Google Scholar, MEDLINE, PubMed, and PsychINFO Database. Key Gap: There is a dearth of research in understanding how COVID-19 affects people with or without a prior personal history of psychosis. Result(s): The systematic review summary provides insight into the state of knowledge. Insights from the systematic review have also been reviewed from the salutogenesis model's perspec-tive. There is moderate evidence of new-onset psychosis during the COVID-19 pandemic in which some antipsychotics treated the psychotic symptoms of patients while treating for COVID-19. Suggestions and recommendations are made for preventive and promotive public health strategies. Conclusion(s): The Salutogenesis model and Positive Psychology Interventions (PPI) provide another preventive and promotive public health management approach.Copyright © 2023 Bentham Science Publishers.
ABSTRACT
Among the lessons learned from the pandemic response are changed perceptions within the industry regarding flex capacity, risk management, supply chain, and inventory control, according to Eric Langer, managing partner at BioPlan Associates. [...]infectious disease drugs have already overtaken perpetual leader oncology as the year's top therapy area for contract manufacturing service agreements, since many of these vaccine-developer companies are small and lack manufacturing capabilities. The expansion will include new suites for the development and clinical manufacturing of drug product intermediates and drug products using spray-drying, hot-melt extrusion, and melt-spray-congeal processing and CGMP suites for early-phase CGMP manufacturing featuring added storage, gowning, and a customer in-plant viewing corridor (4).
ABSTRACT
The US military, intelligence, and diplomatic communities have overlooked a key vulnerability in their assessment of a potential military conflict between China and Taiwan- Taiwan's growing reliance on agricultural imports and its food stocks (except for rice) that could endure trade disruptions for only six months. This article assesses Taiwan's agricultural sector and its ability to feed the country's population if food imports and production are disrupted;identifies the food products that should be prioritized in resupply operations, based on Taiwan's nutritional needs and domestic food production;and outlines the required logistical assets. These findings underscore the urgency for US military planners to develop long-term logistical solutions for this complex strategic issue.
ABSTRACT
The article presents a new diagnostic category, Suicide Crisis Syndrome (SCS), which was proposed to the next revision of Diagnostic and Statistical Manual of Mental Disorders (DSM). Study objective: Adaptation of the Suicide Crisis Inventory (SCI-2) on a Russian sample. Participants: 618 responses to an internet-survey were used, the study lasted from June 16, 2020 to April 26, 2021. Age of the participants: 18-99 (.=26.9;SD=12.8). Gender: 451 females (74.2%), 135 males (22.2%), 32 participants preferred not to answer or chose other gender identity. Instruments: Suicide Crisis Inventory (SCI-2), Suicidal Narrative Inventory (SNI), Stressful Life Events Questionnaire, Columbia Suicide Severity Rating Scale (C-SSRS), questions about recent and lifetime suicidal behavior. Results: Confirmatory factor analyses confirmed the five-factor (chi(2)[1420]=5003.56, p<.001, CFI=.99, TLI=.99, RMSEA=.07, SRMR=.06) and one-factor (chi(2)[1430] = 9847.34, p<.001, CFI=.98, TLI=.98, RMSEA=.10, SRMR=.07) solutions of the inventory, with five-factor as a better solution (Delta chi(2)[10] = 4843.78, p <.001). Based on retrospective data (self-reports on suicidal attempts during the last month), SCI-2 showed good diagnostic qualities (AUC=.85, 95% CI [.72;.97]). The cut-off score was established (80), which indicates the presence of acute suicidal risk. Conclusions: Adaptation of the Suicide Crisis Inventory (SCI-2) went well, the instrument is ready for use for clinical and research purposes.
ABSTRACT
The COVID-19 is associated not only with symptoms of the acute phase, but in some patients some symptoms persist even after overcoming it, we are talking about the so-called post-COVID syndrome. The aim of our work was to identify factors influencing the level of anxiety in patients with this syn-drome. In total, data were obtained from 404 patients, anxiety levels were assessed using the Beck Anxiety Inventory (BAI). The file con-tained 143 men and 261 women, in the age range of 19-90 years. The average BAI value was 13.2 Most often, patients experienced a mild course of covid-19 infection. According to our results, the severity of the COVID-19 infection itself and the presence of comorbid somatic disease have not effect on the BAI value, on the contrary, hospitalization turned out to be a significant factor. Hospitalized patients had a statistically significantly lower level of anxiety than those who experienced this disease at home. Patients with a pathological level of anxiety were significantly younger and, when comparing gender, there were significantly more anxiety in women. The con-nection between the presence of pulmonary post-inflammatory changes on the chest X-ray and the degree of anxiety was not proven, but a statistically significant trend was found.Copyright © 2023, Czech Medical Association J.E.

ABSTRACT
In the Philippines, a barangay is the smallest administrative unit serving as suburban neighborhoods' first line of defense. According to Bautista, barangays conduct a manual file-based process of storing the community's health information. Therefore, the need for a single platform enables a small government unit to manage its resources while being transparent to its community. The study aims to develop a web- based barangay health information system portal for Barangay 69 District 1 in Tondo Manila. The system would be a reference tool for barangays as their platform provides inventory management, the barangay's health programs, and a dashboard for data visualization inventory management, tracking of Covid cases, administration of health activities, and a dashboard for data visualization. As a result, the web portal is functional, and different test scenarios show above-average results. The study concludes that the system provided a platform for the barangay and its residents. It also concludes that it is user-friendly and efficiently disseminates the barangay's health programs and activities. © 2023 IEEE.
ABSTRACT
The COVID-19 pandemic has significantly affected firm performance. As a result, many studies have examined the significance of supply network complexity. Our paper uses the fuzzy set qualitative comparative analysis (fsQCA) method to investigate the causal relationships among the supply network complexity, geographic dispersion, inventory turns, and firm performance. Using a sample of 263 Chinese listed firms, we find that no single factor is necessary to achieve high firm performance during COVID-19 and reveal four paths to produce high performance: operational level driven, supply base complexity driven, and customer base complexity driven with supplier distance, and supply network complexity absence. Furthermore, our findings suggest that supply-based complexity-driven and customer-based complexity-driven can improve firm performance, but not all supply network complexity dimensions can improve firm performance. Hence, firms need to choose the suitable path based on their specific situations.
ABSTRACT
BACKGROUND: Burnout syndrome (BS) has a negative impact among health professionals. AIMS: Our research objective is to quantify the level of burnout in health workers of the Spanish National Health System during the COVID-19 pandemic using and comparing two independent measurement instruments. METHODS: Cross-sectional, descriptive and multicenter study conducted through an anonymous online survey among health workers of the National Health System, measuring the level of burnout using the Maslach Burnout Inventory (MBI) and the Copenhagen Burnout Inventory (CBI). RESULTS: A total of 448 questionnaires were analyzed, the mean age of the participants was 43.53 years (range: 20-64), 365 (81.5%) women. 161 (35.9%) participants presented BS measured with the MBI and 304 (67.9%) measured with the CBI. Regarding work contract, those who had greater job stability presented a higher degree of cynicism with respect to the eventual ones (p = .010), the eventual ones presenting higher mean scores in professional efficacy (p = .034). Urban workers had higher scores of exhaustion (p < .001) and cynicism (p < .001) than those living in rural areas. When comparing both tests, a high predictive value for exhaustion and cynicism was found to measure BS through the CBI (AUC = 0.92 and 0.84, respectively) and a low AUC with respect to the predictive value for efficacy (AUC = 0, 59). CONCLUSIONS: The results obtained show a high level of BS among the health workers who participated in our study. Both tests have an excellent correlation in the degree of exhaustion and cynicism, but not in efficacy. The BS measurement must be performed with at least two validated instruments to increase its reliability.
ABSTRACT
Several countries implemented prevention and control measures in response to the 2019 new coronavirus virus (COVID-19) pandemic. To study the impact of the lockdown due to COVID-19 on multiple cities, this study utilized data from 18 cities of Henan to understand the air quality pattern change during COVID-19 from 2019 to 2021. It examined the temporal and spatial distribution impact. This study firstly utilized a deep learning bi-directional long-term short-term (Bi-LSTM) model to predict air quality patterns during 3 periods, i.e., COVID-A (before COVID-19, i.e., 2019), COVID-B (during COVID-19, i.e., 2020), COVID-C (after COVID-19 cases, i.e., 2021) and obtained the R-2 value of more than 72% average in each year and decreased MAE value, which was better than other studies' deep learning methods. This study secondly focused on the change of pollutants and observed an increase in Air Quality Index by 10%, a decrease in PM2.5 by 14%, PM10 by 18%, NO2 by 14%, and SO2 by 16% during the COVID-B period. This study found an increase in O-3 by 31% during the COVID-C period and observed a significant decrease in pollutants during the COVID-C period (PM10 by 42%, PM2.5 by 97%, NO2 by 89%, SO2 by 36%, CO by 58%, O-3 by 31%). Lastly, the impact of lockdown policies was studied during the COVID-B period and the results showed that Henan achieved the Grade I standards of air quality standards after lockdown was implemented. Although there were many severe effects of the COVID-19 pandemic on human health and the global economy, lockdowns likely resulted in significant short-term health advantages owing to reduced air pollution and significantly improved ambient air quality. Following COVID-19, the government must take action to address the environmental problems that contributed to the deteriorating air quality.
ABSTRACT
PurposeThis study aims to understand how the recent COVID-19 pandemic impacted burnout levels among working mothers in leadership positions and how income and work schemes play an important role in their burnout. Design/methodology/approachData were collected from 961 working mothers and fathers in leadership positions in Mexico under different work schemes during the COVID-19 lockdown. Snowball sampling was used in this study. The Maslach Burnout Inventory General Survey was distributed online, using the burnout scale, with income and work schemes as categorical variables. FindingsBurnout levels among working mothers in leadership positions were higher than those among working fathers. The hybrid work scheme (i.e. working from home combined with working from office) lessens burnout in working mothers, contributing both theoretically and empirically to better understanding burnout levels of mothers in leadership positions. Practical implicationsThe findings can encourage human resource areas to reflect on the overexertion and work stress of mothers in leadership positions, and potential support resources can be provided to motivate them and retain their talent. Originality/valueThe introduction of the notion of lockdown in a conceptual model to observe its interaction with burnout and hybrid work schemes (i.e. working from the office and home) has rarely been discussed in existing literature. The impact, especially for working mothers in leadership positions, must be thus carefully considered while dealing with future crises, thereby helping to develop policies and processes accordingly.
