ABSTRACT
Emergencies have a significant impact on the economy. Thus, effective prevention and control measures can reduce economic losses to the greatest extent. Taking the novel coronavirus outbreak as the starting point, we proposed the SEEIR-E model, an optimization model of the SEIR. The model compares two different prevention and control modes, 'fence mode' and 'free-range mode' Combined with the big data of the epidemic, systematic simulation and analysis were carried out in the Netlogo simulation environment. When environmental factors are the same, the 'fence model' can control the spread of the disease more quickly, and the economic impact is less. At the same time, the impact of various environmental factors on economic recovery was simulated and analyzed. The result provides a basic understanding in economic recovery after the epidemic. © 2022 IEEE.
ABSTRACT
With the widespread use of applications and services supporting audiovisual calls via smartphones, both in business and leisure contexts, a key challenge for service providers is meeting end user Quality of Experience (QoE) expectations and requirements. To successfully meet this challenge, there is a need to identify and analyze the key system-related factors impacting user perceived quality. In this paper, we contribute beyond state-of-the-art by conducting a large scale web-based questionnaire survey to investigate the system-related factors that subjects identify as most influential in contributing to their overall experience and quality perception. We focus in particular on leisure audiovisual calls, established via mobile devices. Our initial survey (Phase 1) was conducted in Feb. 2020, just prior to the outbreak of the COVID-19 pandemic (272 participants). To investigate if the importance of factors has changed due to increased usage of the service caused by the pandemic among the general population, we conducted a second survey (Phase 2) in October 2021 with 249 participants. Based on obtained results, we identify key system-related QoE influence factors belonging to three categories: media quality, functional support, and usability and service design. We observe no significant differences in user opinions and expectations prior to and during the period of increased service usage, despite different participant demographics and study time frames, thus contributing to generalizability of obtained results. Study results contribute to providing insights for designing future user studies investigating QoE, in terms of key factors that should be considered.
ABSTRACT
The COVID-19 pandemic has had a huge impact on people's consumption behavior and habits. This paper takes Shanghai, China as a case study and uses a questionnaire survey of urban residents in all districts in Shanghai from April to May in 2022. Herein, we empirically analyze the factors affecting shopping modes for agricultural products, describe how things have changed compared to before the outbreak of the pandemic, and explore the underlying mechanism. This paper can provide a policy reference for how to ensure the safety of people's food supply in the context of the COVID-19 pandemic. The results show that urban residents pay more attention to the basic attributes of agricultural products such as the quantity guarantee and health safety, and will adjust their consumption modes for agricultural products according to the needs of families and management. Compared with shopping malls and supermarkets, the quantity and quality assurance of community groups and e-commerce platforms can better meet the consumption situation of agricultural products during the pandemic period. The moderating effect of consumer commodity preference in the positive influence of safety evaluation on the transformation of shopping mode is significant. In general, online e-commerce platforms and community group buying have played a significant role in ensuring the acquisition of supplies needed by people during the COVID-19 pandemic. However, it remains to be determined whether the changes in the shopping modes for agricultural products of urban consumers brought by the current COVID-19 pandemic are long term or solidified.
ABSTRACT
Objective To understand the willingness and factors of children's parents for COVID- 19 inoculation,and to provide the basis for the formulation of COVID- 19 inoculation strategy. Methods Easy sampling was used to conduct questionnaire survey on parents of 215 children from a Grade AAA hospital in Wuhan between December 2020 and January 2021. Results One hundred and fifteen valid questionnaires were collected, and 96.74% of parents had heard of COVID- 19 before this survey. WeChat accounts 43.72%(94/215) and Tiktok accounts 28.37%(61/215) were main sources of COVID- 19 and vaccine- related knowledge. 90.23%(194/215) of the parents of children were willing to be inoculated against COVID- 19, and 9.77%(21/215) of children’s parents weren’ t willing to be inoculated against COVID -19 vaccine, mainly because they believed that the interval between the development and use of the vaccine was short,the necessity of time spending in considering(38.10%, 8/21),concerns about adverse effects and safety(47.62%,10/21). Parents of children with a bachelor's degree(OR=0.034,95% CTJO.002-0.582) and a monthly income of 5 000 to 7 999 Yuan(OR=11.459,95%CI-1.708-76.870) were more likely to inoculate COVID- 19 vaccine. Conclusion Parents of children have high willingness to inoculate COVID- 19 vaccines, while they show concerns about adverse reactions and safety of vaccines. The authorities concerned are recommended to strengthen the publicity of inoculation knowledge of COVID- 19 to thereby ease public doubts and ensure safe and effective promotion of vaccines. © 2022, Editorial Department of Medical Pest Control.

ABSTRACT
The satisfaction of highly educated citizens with community services for COVID-19 represents the attitude of the middle class and plays an important role in both the social and political stability of a country. The aim of this paper was to determine which factors influence public satisfaction with COVID-19 services in a highly educated community. Through a literature review and using the American Customer Satisfaction Index (ACSI) model, this paper constructed a public satisfaction model of community services for COVID-19 and proposed relevant research hypotheses. A community with many highly educated residents in Beijing was selected as the case study, where 450 official questionnaires were distributed based on the age ratio of residents, with 372 valid questionnaires being collected from May 2021 to July 2021. The study results obtained by a structural equation model (SEM) show that: (1) public satisfaction is significantly and positively influenced by quality perception (0.305 **), public demand (0.295 **), and service maturity (0.465 ***); (2) public satisfaction has a significantly positive effect on service image (0.346 ***) and public trust (0.232 **), and service image significantly affects public trust (0.140 *); (3) service maturity is positively influenced by public demand (0.460 ***) and quality perception (0.323 *); and (4) public demand is positively influenced by quality perception (0.693 ***) (* p < 0.05; ** p < 0.01; *** p < 0.00). The conclusions of the study can provide suggestions and recommendations to improve the satisfaction of highly educated residents with community healthcare services during the COVID-19 pandemic.

Physical activity and sports are a central part of individuals' lives throughout the life cycle. During adolescence, its regular practice may contribute to the development of healthy adult lifestyles, decreasing chronic disease incidence. Therefore, the reasons that drive adolescents to start practicing sports in a certain club may be multiple and understanding such causes can be important to design and implement public policies to promote active lifestyles for everyone. In this article, we report the core findings of a research on why young athletes do sports, how they choose their team-training club and how COVID-19 has had an impact on their routines. From a methodological viewpoint, a questionnaire was developed and sent to sport clubs located in NUTS2 Centro Region, Portugal, and results were analyzed through the use of geographic information systems and statistical analysis, namely association tests (Chi-square test), difference tests (Mann-Whitney test and Kruskal-Wallis test), logistic regression and descriptive analysis. Findings show that family, age group, friends, proximity to sports facilities, teammates, and club conditions are the factors that influence adolescents the most. In short, external factors have a significant preponderance to practice physical activity and choose a sports' club. These findings can provide useful insights for clubs, coaches and policy-makers to become more aware of the relationship between sports practice and accessibility to sports halls, as well as the athletes' behavior and their connection with the club and basketball practice. As such, these findings can motivate the design of initiatives and strategies to boost sports practice and to find ways for clubs to attract more adolescents.
ABSTRACT
Aim: We investigated to understand post-traumatic stress disorder (PTSD) during the coronavirus epidemic, and related influential factors. We hoped to provide more basis for targeted services to improve public psychological health care. Methods: From the psychological aid platform set up by the Wuhan Mental Health Center, we obtained online sample data of Chinese residents during the coronavirus epidemic. We used the PTSD examination scale as the study tool and analyzed the data with SPSS. Results: A total of 376 data was collected. The PTSD degree of the public was 45.93 +/- 17.32, the positive detection rate was 63.56%, and the PTSD level increased with fluctuation. Participants' gender, educational level, and location were the influential factors. Specifically, women, lower educational backgrounds, and people in Wuhan were more likely to have PTSD. Conclusions: The epidemic had a great impact on people's psychological status. Although the epidemic has basically been brought under control, PTSD levels have not declined. Therefore, it is necessary to provide timely psychological assistance for people in need, and help them adapt to life as soon as possible. (PsycInfo Database Record (c) 2022 APA, all rights reserved)
ABSTRACT
Objective To describe the spatial distribution of COVID-19 cases in Shaanxi Province and further explore its relevant factors, so as to provide evidence for the prevention and control of COVID-19 in Shaanxi Province. Methods The information of confirmed COVID-19 cases and relevant socioeconomic data in Shaanxi Province were collected. The temporal and spatial distribution characteristics of confirmed cases, and the correlation between the incidence of COVID-19 and socioeconomic factors in the population were analyzed by using a generalized linear model. Results Four cases were first reported in Shaanxi on 23 January 2020, with the highest number of new confirmed cases reaching 23 on 4 February and no new cases after 19 February. The imported cases appeared earlier and reached the new peak than the local cases, and entered the zero stage earlier than the local cases. The spatial distribution showed that Xi′ an (120 cases) had the largest number of confirmed cases, accounting for 48.98% of the total cases, and the districts with more confirmed cases were in Lianhu, Yanta, Xincheng and Weiyang. Socioeconomic factors which significantly associated with the number of confirmed cases in each district and country were education expenditure (IRR=0.287, 95% CI: 0.134-0.612), GDP per capita (IRR=1.143, 95% CI: 1.049-1.245) and the distance from Wuhan (IRR=0.995, 95% CI: 0.992-0.998). Conclusion Measures should be taken in key areas and population at the early stage of the epidemic to control the spread of the epidemic as soon as possible. © 2021, Publication Centre of Anhui Medical University.

ABSTRACT
European economic processes have always been the center of public interest. 2010-2019 were characterized by economic development and result achievements in the conditions of information flows exchange and digital changes. However, the pandemic effects of Covid-19 have negatively influenced economic activity, causing significant uncertainty in subsequent economic processes, which were reflected in GDP trends and determined the non-stationary economic conditions. And although the first half of 2021 marks GDP growth, the economic recovery, projected in the traditional scenario, is not enough to reach the precrisis level of production again. The purpose of the study is to identify the effects on European countries economic development and to develop proposals for directions and instruments of regulatory policy transformation, which would take into account the current non-stationary economic conditions. Achieving the goal led to the usage of scientific and practical methods of cognition, including the method of deduction and induction, system analysis, synthesis, generalization, mathematical methods and models. The study characterizes the nature of non-stationary economic development and identifies the need for regulatory influence to ensure further economic growth. The analysis proposes to use GDP as an indicator of economic processes dynamics with the specification of system of direct and indirect influence factors using a multifactor dynamic model. The assessment of depth and nature of their impact allowed to divide them by the stationary and non-stationary criterion. On the basis of received values the directions of regulatory policy transformation in the conditions of non-stationary economic processes have been offered.
ABSTRACT
PURPOSE: Some studies have shown that patients with coronavirus disease 2019 (COVID-19) still have sequelae after discharge. However, little is known about the long-term physical and psychological sequelae of patients, especially factors that influenced the prognosis. PATIENTS AND METHODS: Patients with COVID-19 were followed up for 6 months. The psychological status of patients was evaluated by DASS-21 questionnaire, while physical functions were determined using medical history, laboratory examination, thoracic computed tomography (CT), and echocardiography. RESULTS: Fifty patients infected with COVID-19 were enrolled, and 11 (22%) patients still showed symptoms related to COVID-19. The mean contents (cells/ul) of CD3+ cells, CD4+ and CD8+ T, B lymphocytes and NK cells of the survivors elevated significantly after 6-month discharge (P < 0.001). The frequency of ground-glass opacities and consolidations decreased from 90% to 42% (P < 0.001), and 54% to 20%, (P = 0.001), respectively, while the changes of reticulation and bronchiectasis were insignificant (P > 0.05). The frequency of left ventricular diastolic dysfunction decreased from 40% to 15% (P = 0.002). Depression was observed in 5 (12.5%) participants, stress in 3 (7.5%), anxiety in 6 (15%), and among them 1 (2.5%) showed extremely severe anxiety. Covariation analysis elucidated age might be a risk factor (OR: 1.09, 95% CI: 1.01-1.18, P = 0.038), while NK cell was a good prognostic factor for pulmonary recovery. The comorbidities were significantly positive correlated with persist pulmonary damage (r = 0.33, P = 0.020). Compared with patients with antiviral therapy, patients without antiviral therapy had higher anxiety score (3 vs 0, P = 0.033). CONCLUSION: After 6-month discharge, the persisting cardiopulmonary damage was observed in recovery patients, and psychological implications should not be ignored. Age, comorbidities, NK cell and antiviral therapy might be associated with the prognosis of COVID-19.
ABSTRACT
OBJECTIVE: Information regarding the epidemiology and clinical features of mild to moderate patients caused by COVID-19 in Fangcang Hospital is scarce. Through a retrospective cohort study, the clinical characteristics of COVID-19 patients in Dongxihu Fangcang shelter hospitals were analyzed, and the factors that affected the disease progression of COVID-19 patients were explored. METHODS: The clinical characteristics of 714 patients with COVID-19 were retrospectively analyzed at Dongxihu Fangcang Hospital between February 7 and March 8, 2020. We described the clinical characteristics and distribution of discharge or transfer times for each patient. According to the disease progression of COVID-19 patients, we divided all patients into Non-Deteriorated group and Deteriorated group. Furthermore, binary logistic regression was used for a single outcome and multiple response variables. RESULTS: We treated 789 patients with mild and moderate COVID-19, of which 714 were included in this study, which included 326 (45.66%) deteriorated patients and 388 (54.34%) non-deteriorated patients. The mean age of the study population was 48.16±12.44 years. Of all patients, 319 (44.7%) were men and 395 (55.3%) were women. The average length of the patient's stay was 16.08±5.13 days. The most common clinical feature on admission was fever (593 of 714, 83.05%). It is worth noting that 80 (11.20%) of the 714 patients were asymptomatic from exposure to admission. Multivariate logistic regression analysis showed that gender, age, diabetes, respiratory system disease, fever, dyspnea, and nasal congestion were risk factors associated with deterioration in cases with COVID-19 patients, and asymptomatic (OR: 0.058; 95% CI: 0.022-0.155; P<0.001) was the protective factor for deterioration of COVID-19 patients. CONCLUSION: Accompanied by chronic diseases, old age, fever, nasal congestion, and dyspnea were factors that influenced the aggravation of COVID-19 patients, and more attention and treatment should be given to these patients.
ABSTRACT
Harmonious and stable family relations are undoubtedly an important component of victory in terms of epidemic prevention. Take the COVID-2019 (2019 new crown pneumonia epidemic) as the major public events background; 24,188 national samples were obtained based on a network survey. We selected gender, education level, occupation type, family scale, neighborhood relationship and psychological state as independent variables, and adopted multiple logistic models to assess the impact of major public events on family relationships and the characteristics of humanistic-regional attributes. The findings are as follows: (1) During the epidemic period, major public health emergencies effectively promoted the national residents' family relationships. (2) The family relationships of national residents presented a high level in central China and a low level in the border areas of China, which is consistent with the spread of COVID-2019 in January and February. (3) Family relationship level averages between 2.201~2.507 among different groups when divided by occupation, age and education. The family relationship has improved, but the change is not drastic and the gap between various groups is not significant, so there is essentially no difference. (4) The impact of major public health emergencies on all families is nearly sudden and instant, so that family relationship changes are often also abrupt. (5) Educational level, family size and gender have a positive effect on the change in family relations, but this effect is weakened as family education level increases; while the anxiety of the interviewees and the neighborhood had a negative effect on the change in family relationship, this indicates that the better the neighborhood relations are, the more harmonious a family relationship is. The above research can provide an important scientific support and decision-making basis for the government to carry out community prevention work, respond to major public health emergencies and construct a family support social policy system in the future.

The novel coronavirus (COVID-19) has become a pandemic and the risk perception plays an important role in self-protection and spread prevention. This study attempts to explore the intrinsic characteristic of risk perception and the spatial distribution of it, which have not been involved in previous studies. To attach this purpose, data from questionnaire conducted in China and Korea (samples of 897 respondents in China and 340 respondents in South Korea) are used to produce risk perception of COVID- 19. Results reveal four principal findings: (1) risk perception of COVID-19 can be categorized into perceived social risk and perceived risk of being infected; (2) the internal differences are most pronounced in perceived risk of being infected about oneself in China, and in perceived social risk disorder about local community in South Korea; (3) the spatial distribution of risk perception is not consistent with that of epidemic severity, for high-risk perception spread out beyond the epicenter with different performance in the two categories; and (4) among the influence factors, trust in information, familiarity with epidemic situation, and interpersonal distance from suffers in the epicenter are found to have a significant influence on different aspects of risk perception. The theoretical and practical implications of this study enrich the understanding of risk perception of epidemic, and provide specific suggestions for preventing this ongoing epidemic spread across the population.
ABSTRACT
The objectives of this study were to investigate the status and influence factors of caregiver's quality of life (QOL) on caring for patients with chronic wound during COVID-19 epidemic. A prospective cross-sectional study of 83 informal caregivers was included. The characteristics of informal caregivers as well as their QOL assessment by the Family Dermatology Life Quality Index (FDLQI) were measured, respectively. Single-factor analysis and multiple regression analysis were carried out to explore the independent influence factors of QOL of caregiver on caring for patient with chronic wound. 62.65% of the caregivers were female with a mean age of (54.24 ± 12.6) years, and 34.9% of the caregivers were parents. The mean FDLQI score was 13.01 ± 7.53 at a high level. The following variables influenced the FDLQI scores of caregivers: self-care ability of patients, patient's satisfaction of home-based wound care, and home-based wound care need of caregivers. The model was able to explain 29.9% of variance in QOL of caregiver (F = 6.561, P = .000, R2 = 0.299, adjusted R2 = 0.253). In conclusion, the impact of chronic wound disease on the QOL of caregivers is heavy during COVID-19 epidemic. Wound professionals are suggested to pay attention to wound care need at home and QOL of caregiver on caring for patients with chronic wound during COVID-19 epidemic and develop tailored wound health education and support programme in order to improve the QOL of caregivers.
