A new hand rehabilitation system based on the cable-driven mechanism and dielectric elastomer actuator
Authors: Amin Heba , Assal Samy F. M. , Iwata Hiroyasu
Published: October 2020

Abstract. The increasing number of patients with hand disabilities after strokes or peripheral nerve injuries necessitates the continuous development of rehabilitation system devices to accelerate muscle recovery and to help patients regain the motor functions of their hands. This paper introduces the design of a hand rehabilitation system for patients who have a solitary impairment of their hand extension. The system was designed to be portable, simple, and cheap. Using a system based on a cable-driven mechanism instead of traditional rigid links reduces the degrees of freedom of the finger to one. The dielectric elastomer actuator was designed and fabricated as a smart actuator for the system, which supports the low cost of the system. A kinematic analysis of the cable-driven mechanism has been done. Parameters of the actuator were optimized to reach the required output. In order to characterize the performance of the actuator, a uniaxial tension test, isotonic test, and isometric test have been implemented.

Resumption and Optionality in Arabic Definite Restrictive Relatives
Authors: Abdel-razaq Issa
Published: October 2020

The present study examines the claim that definite relative clauses in Modern Standard Arabic exhibit free variation between resumptive pronouns and gaps. The implication of such a claim presents a problem for minimalist syntax that does not tolerate true optionality. To solve this problem, the study argues that the original claim is incorrect and that despite similarities in the PF outputs, resumptive relatives are syntactically different from gapped relatives. While the latter is derived from a standard VSO structure, I propose, the former is derived from a topic-comment structure that already contains an RP. Thus, the fact that resumptive relatives contain resumptive pronouns has nothing to do with relativization, as is generally assumed. The study demonstrates that both resumptive relatives and gapped relatives are derived by movement in contexts that do not involve islands. As it turns out, resumption in relatives is used only as a last resort strategy to save structures in which movement is genuinely blocked, such as islands, from crash. Altogether the study concludes that the variation observed does not reflect true optionality, a finding that supports robust economy principles of minimalist syntax.
Cash Flow in an Agribusiness Restructuring Process
Authors: Junior Rubens Corrêa , Gameiro Augusto Hauber
Published: October 2020

The purpose of this article is to present cash flow as an accessible and efficient tool for the management of small and medium-sized egg companies, including those close to bankruptcy, aiming at their financial recovery. In order to achieve results, action research and the cash flow management method were adopted. The data were collected from a Brazilian egg producer that was close to bankruptcy. Data collection, implementation of the management tool and performance monitoring took place between July 2016 and December 2017. The use of the cash flow tool allowed the company’s financial recovery, which led to an increase of 951.5% in its cash and cash equivalents at the end of the research period, generating 22.5% of cash on the operating result and maintaining its minimum balance of cash by 23.6% above the limit required for it to keep operating safely. The method considered only the Cash Flow Statement, as it is the most practical and easy to understand for managers who have no management experience or training. The Balance Sheet and Income Statement were not explored. From the research results it is expected that the proposed management tool would be adopted by other small and medium-sized egg producers in Brazil, as well as in other branches of agribusiness. Hitherto, we are not aware of the availability of a tool proposed for small and medium companies in the animal production segment in Brazil. Therefore, it could be a valuable contribution to the socioeconomic development of this sector.

Published: October 2020

The objective of this study was to evaluate the effect of the use of different chemical compounds combined with ultrasound bath on the sanitization of minimally processed carrots. The sanitizers sodium hypochlorite, peracetic acid, and sodium dichloroisocyanurate were investigated, all of them associated with the ultrasound bath, and the aerobic mesophiles and E. coli counts were evaluated. Sodium hypochlorite associated with ultrasound reduced the population of aerobic mesophiles and E. coli by 0.23 and 1.88 log cycles, respectively. For sodium dichloroisocyanurate associated with ultrasound, the reduction was 3.06 and 2.76 log cycles, while for the association with peracetic acid, this reduction was 2.72 and 2.35 log cycles. Thus, the effect of the ultrasound bath and sodium dichloroisocyanurate increased the decontamination efficiency of the minimally processed carrots. In addition, there is an alternative to the use of sodium hypochlorite, once they are not involved in reactions with organic compounds and the formation of trihalomethanes, which are harmful to health.

Orbignya phalerata Mart. has great socio-economic value, originating various products and by-products; however, there are few studies about obtaining food products from of this raw material. In face of that reality, this study aimed to obtain powder extract from press cake of the babassu nut kernel, and to verify the influence of varying concentrations of Maltogill®10 and drying temperature on process yield through a factorial design, as well as to characterize the final product. Babassu nut used for pressing and acquisition of residual press cake and extract. Spray dryer was used to obtain the powder extract, which adopted a rotating central composite design (RCCD with 11 trials). The final product was characterized by analyses of moisture, solubility, hygroscopicity, water activity and bulk density. The experimental design showed significant influence (p ? 0.05) for the variables inlet temperature in the linear and quadratic models, focusing only on the linear term and the interaction between them, the model adjusted in planning was considered predictive; the best productivity obtained (80.37%), was for the temperature of 95°C with encapsulating agent of 18%. With respect to the powder product analysis, low moisture values, hygroscopicity, and density were observed, as solubility and water activity within the recommended parameters.

Published: October 2020

The objective of this study was to evaluate the efficiency and cost of two distinct hormonal protocols for induction of puberty in Bos indicus heifers in the western Amazon region. Nelore prepubertal heifers (n = 127) aged 20 to 24 months (21 ± 0.3 months) and weighing 300 to 340 kg (318 ± 7 kg) were submitted to two distinct protocols for induction of cyclicity. Females were previously submitted to two ovarian ultrasound examinations (12-day interval) to verify the absence of the corpus luteum (CL). Then, the heifers were divided into two experimental groups: G-CIDR/EC (n = 54) and G-P4/EC (n = 73). The G-CIDR/EC group utilized a CIDR® for 12 days and on the day of its withdrawal, 0.6 mg of estradiol cypionate (IM) was administered. The G-P4/EC group received 150 mg of injectable progesterone (IM) and one injection of 0.6 mg EC 12 days after the progesterone injection. Twelve days after the end of the hormonal protocols, the heifers were submitted to another ultrasound evaluation for identification of cyclicity (ovulatory follicle or CL). These females were then submitted to a conventional protocol of synchronization of ovulation for timed artificial insemination (TAI). Only heifers responsive to puberty induction (G-CIDR/EC (n=30) and G-P4/EC (n=51)) were included in the TAI protocol. After seven days of insemination, both groups were exposed to natural breeding. In addition, an economic analysis was performed to evaluate cyclicity induction, the TAI protocol, and pregnancy in both groups. The G-CIDR/EC group showed 81.48% (44/54) of females responsive to induction of cyclicity (presence of CL) while the G-P4/EC group obtained 86.3% (63/73; p=0.463). Regarding the conception rate to TAI and to bull (natural breeding), the G-CIDR/EC group displayed 43.33% (13/30) and 33.33% (10/30), respectively, and the G-P4/EC group exhibited 54.9% (28/51) and 39.22% (20/51), respectively. The overall pregnancy rate (TAI+Bull) was 76.67% (23/30) in the G-CIDR/EC group compared to 94.12% (48/51; P=0.023) in the G-P4/EC group. The cost of the hormonal protocol to cyclicity induction resulted in an economy of 42.8% for injectable P4 compared to the intravaginal P4 group. In addition, the final cost of cyclic induction associated with TAI was 34% lower in the G-P4/EC group compared to the G-CIDR/EC group. We concluded that both cycling induction protocols were efficient in Bos indicus heifers from the western Amazon. However, injectable P4 provided a higher conception rate and lower pregnancy cost at the end of the reproductive season.
Effect of the addition of sodium caseinate on the viability of cryopreserved buffalo semen

Published: October 2020

The use of cooled semen in artificial insemination operations results in higher pregnancy rates than the use of frozen semen. This result seems to be related to the more severe damage triggered by the freezing process than that observed during refrigeration. Due to its ability to bind to sperm-binding proteins and calcium ions, sodium caseinate has been studied as a substance capable of preventing early sperm capacitation, a significant cause of the decreased pregnancy rate resulting from the use of frozen semen. The first objective of this study was to evaluate whether a commercial egg yolk diluent developed for frozen bovine semen could be used for buffalo semen cryopreservation; the second objective was to investigate the effect of this diluent in combination with sodium caseinate during the procedures of buffalo sperm cryopreservation using flow cytometry and computer-assisted sperm analysis. In the first part of the study, comparing the results of spermatic kinetics and plasma and acrosomal membrane integrity, it was observed that the freezing process resulted in more cell damage than the cooling process. In the second part of the study, no effects of the addition of sodium caseinate to the egg yolk diluent were observed. From the results of the present study, it was possible to conclude that the egg yolk-based diluent was suitable for buffalo semen cryopreservation and that the addition of sodium caseinate did not decrease the harmful effects related to seminal cryopreservation.

Published: October 2020

We examined the production performance of Nellore heifers fed high-concentrate (90%) diets in which ground corn (GC) was substituted by ground soybean hulls (SH) at increasing levels (0, 33, 66, and 100%), in the concentrate portion. A total of 144 heifers (263.40 ± 13.90 kg average initial weight; 27 months old) received the test diets in a feedlot for 112 days. The experiment was set up as a completely randomised design with four treatments. Data were subjected to ANOVA and orthogonal contrasts, adopting ? = 5%. The sum of squares of treatments in the contrast analysis was decomposed into two orthogonal contrasts (L - linear and Q - quadratic effect) for the level of SH substituting GC. Dry matter intake was not changed by the GC substitution levels, averaging 2.51% of body weight. There was a linear increase in neutral detergent fibre intake (1.08, 2.03, 2.92, 3.78, 4.85 kg/day) and feed conversion (6.20, 7.08, 7.77, and 8.67 kg/kg); and a linear decrease in total digestible nutrient intake (5.78, 5.16, 5.03, 5.12, and 3.66 kg/day), average daily gain (1.24, 1.11, 1.02, and 0.89 kg/day), and slaughter weight (383.52, 374.71, 363.25, and 366.27 kg) as the substitution level was increased (0, 33, 66, and 100%, respectively). Subcutaneous fat thickness and loin-eye area were not influenced (P > 0.05), averaging 5.30 mm and 53.09 cm2, respectively. Substituting ground corn by ground soybean hulls in high-concentrate diets determined a reduction in production performance of feedlot-finished Nellore heifers.
Managerial Empowerment and Its Impact on Managerial Creativity: An Empirical Study in Greater Amman Municipality
Authors: Nawaf Al Homud Nehaya
Published: October 2020

Many organizations have collapsed due to lack of creativity and others have also made giant strides due to the creative and innovative ideas of the managers. Hence, creativity is important concept that can change the fortunes of organizations. This study has been conducted to examine the impact of the managerial empowerment on managerial creativity in Greater Amman Municipality. Managerial empowerment has been taken as independent variable. Freedom of choice, self-efficacy, and development of job has been used as the proxy dimensions of managerial empowerment. Moreover, managerial creativity has been taken as dependent variable. Creativity in the product, marketing creativity, and regulatory creativity have been used as the proxy dimensions of managerial creativity. Questionnaires have been used to collect data. The results highlighted that all the dimensions of managerial empowerment are statistically significant on the creativity in the product. The study recommended that proper attention should be paid to the empowerment of workers, especially in the lower administrative levels by encouraging them to take on responsibilities and to look at their mistakes in order to enhance the potential for creativity in Greater Amman Municipality.
Asymptotic solutions of nondiagonal linear difference systems
Authors: Naulin Raul , Pinto Manuel
Published: October 2020

This paper, relying on dichotomic properties of the matrix difference system $ W(n+1)=A(n)W(n)A^{-1}(n)$, gives conditions under which a perturbed system $ y(n+1)=(A(n)+B(n))y(n)$, by means of a nonautonomous change of variables $ y(n)=S(n)x(n)$, can be reduced to the form $ x(n+1)=A(n)x(n)$. From this, a theory of asymptotic integration of the perturbed system follows, where the linear system $ x(n+1)=A(n)x(n)$ is nondiagonal. As a consequence of these results, we prove that the diagonal system $ x(n+1)=\Lambda(n)x(n)$ has a Levinson dichotomy iff system $ W(n+1)=\Lambda(n)W(n)\Lambda^{-1}(n)$ has an ordinary dichotomy.

Oscillation criteria for differential equations with piecewise constant argument
Authors: Luo Zhiguo , Shen Jianhua
Published: October 2020

We obtain some new oscillation and nonoscillation criteria for the differential equation with piecewise constant argument $$ x'(t) + a(t)x(t) + b(x) x([t-k]) = 0, $$ where $ a(t) $ and $ b(t) $ are continuous functions on $ [-k, \infty) $, $ b(t) \ge 0 $, $ k $ is a positive integer and $ [ \cdot ] $ denotes the greatest integer function. The method used is based on the treatment of certain difference equation with variable coefficients. Our results extend theorems in [15]. As a special case, our results also improve the conclusions obtained by Aftabizadeh, Wiener and Xu [3].

Nonparametric Bayes estimators for hazard functions based on right censored data
Authors: McKeague I. W. , Tighiouart M.
Published: October 2020

In this article, we analyse right censored survival data by modelling their common hazard function nonparametrically. The hazard rate is assumed to be a stochastic process, with sample paths taking the form of step functions. This process jumps at times that form a time-homogeneous Poisson process, and a class of Markov random fields is used to model the values of these sample paths. Features of the posterior distribution, such as the mean hazard rate and survival probabilities, are evaluated using the Metropolis--Hastings--Green algorithm. We illustrate our methodology by simulation examples.

Investigation of the efficacy of mycotoxin-detoxifying additive on health and growth of newly-weaned pigs under deoxynivalenol challenges
Authors: Holanda Debora Muratori , Kim Sung Woo
Published: October 2020

Objective: This study evaluated the effects of feeding diets naturally contaminated with deoxynivalenol (supplemental 2 mg/kg) on health, growth, and the effects of a mycotoxindetoxifying additive in newly-weaned pigs.Methods: Thirty-six pigs (27 day-old) were housed individually and assigned to 3 treatments for 5 weeks: CON (diet containing minimal deoxynivalenol), MT (diet with supplemental 1.9 mg/kg of deoxynivalenol), and MT+D (MT + mycotoxin-detoxifying additive, 0.2%, MegaFix, ICC, São Paulo, Brazil). The mycotoxin-detoxifying additive included bentonite, algae, enzymes, and yeast. Blood was taken at week 2 and 5. Jejunal tissue were taken at week 5. Data were analyzed using the MIXED procedure of SAS.Results: Pigs fed MT+D tended to have decreased (p = 0.056) averaged daily feed intake during week 1 than MT. At week 2, serum aspartate aminotransferase/alanine aminotransferase in MT tended to be lower (p = 0.059) than CON, whereas it was increased (p< 0.05) for MT+D than MT, indicating hepatic damages in MT and recovery in MT+D. Pigs fed MT had lower (p<0.05) blood urea nitrogen/creatinine than CON, supporting hepatic damage. At week 5, pigs fed MT tended to have reduced (p = 0.079) glucose than CON, whereas it was increased (p<0.05) for MT+D than MT, indicating impaired intestinal glucose absorption in MT, which was improved in MT+D. Pigs fed CON tended to have increased (p = 0.057) total glutathione in jejunum than MT, indicating oxidative stress in MT. Pigs fed MT+D had a reduced (p<0.05) proportion of Ki-67-positive cells in jejunum than MT, indicating lower enterocyte proliferation in MT+D.Conclusion: Feeding supplemental 1.9 mg/kg of deoxynivalenol reduced growth and debilitated hepatic health of pigs, as seen in leakage of hepatic enzymes, impaired nitrogen metabolism, and increase in oxidative stress. The mycotoxin-detoxifying enhanced hepatic health and glucose levels, and attenuated gut damage in pigs fed deoxynivalenol contaminated diets.

There were used the spherical lenses in industry conventional for long time, but new types of lenses were created during innovation processes. One type of lenses is aspherical. Two main parameters describing quality of aspherical lenses are accuracy of the form shape and surface roughness. These parameters can be obtained after last operation – polishing. Technical parameters that give the biggest influence to form shape and surface roughness were investigated in this experiment and optimal technical parameters for polishing process were established. Melted quartz ,,UVFS” was used in this research, investigations were carried out according by full factorial design. Five axis CNC machine Schneider SCPA100 was used for polishing and profilometer Nanoscan 855 was used for measurements. After analysis of results it was found out that speed of rotation and penetration depth are the most important factors in polishing process. For getting the best shape it’s necessary to use the smallest chosen values of speed of rotation and penetration depth, for getting the best surface roughness polishing parameters changing conversely. The smallest value of surface roughness Rz was 0.06 µm, and shape deviation was 2.6 µm. Optimal polishing parameters for the best quality of aspherical lenses was provided.

Die Kohäsionspolitik der Europäischen Union spielt eine Schlüsselrolle dabei, die Unterschiede im Entwicklungsstand der Regionen in der EU zu verringern, um den wirtschaftlichen, sozialen und territorialen Zusammenhalt zu stärken. Geplant und umgesetzt wird die Kohäsionspolitik in der EU im Rahmen eines mehrere Ebenen umfassenden Systems („Mehrebenen-Governance-System“), an dem ein breites Spektrum von Stakeholdern beteiligt ist. Für den Programmplanungszeitraum 2007-2013 wurde erstmals auf nationaler Ebene ein förmliches dreistufiges Kontrollsystem eingeführt, dessen erste „unabhängige“ Prüfebene die Prüfbehörde ist. Aus vorläufigen Studien geht hervor, dass die Einführung der Prüfbehörden ein Meilenstein bei der Stärkung des Verwaltungs- und Kontrollsystems für die Ausführung des EU-Haushalts war und somit dazu beigetragen hat, den EU-Haushalt vor nicht förderfähigen Ausgaben zu schützen. Im vorliegenden Aufsatz wird analysiert, ob sich die Arbeit der nationalen Prüfbehörden im Rahmen der EU-Kohäsionspolitik auf den Grad der Zuverlässigkeit der EU-Ausgaben in diesem Bereich auswirkt. In diesem Aufsatz wird der Zusammenhang analysiert, der zwischen der Entwicklung bei den vorschriftswidrigen Ausgaben und der Entwicklung der den Prüfbehörden übertragenen Aufgaben besteht. Es soll vor allem festgestellt werden, ob die Entwicklung der Zuständigkeiten der Prüfbehörden zu einem robusteren Verwaltungs- und Kontrollsystem für die Umsetzung der Kohäsionspolitik beigetragen hat.

Published: October 2020

The exploitation of nature for decades due to several anthropogenic activities has changed the climatic conditions worldwide. The environment has been polluted with an increase of greenhouse gases. The major consequences are global warming, cyclone, an increase in sea level, etc. It has a clear negative impact on the natural environment including aquatic ones. As a result, production of fish in the aquaculture system and marine system is greatly affected. Marine ecosystems like coral reefs are also destroyed. Decreased fish production has also affected the livelihood and economic condition of the fish farmers. So, corrective measures should be taken to reduce the climate changes for minimizing its effects on fish production. Using more eco-friendly substances, planting more trees, and preserving our nature are some steps to be taken. Awareness should also be generated among the common people.

Published: October 2020

Curcuma comosa (Zingiberaceae) is widely grown in tropical and subtropical areas of Asia, like Thailand, Indonesia, Malaysia, and Myanmar. In Myanmar, the rhizome of Curcuma comosa is called Sa-nwin-ga, and local people had used it as a traditional medicine for stomach ache, diabetes mellitus, and hypertension. This species produces secondary metabolites of phenolic and nonphenolic groups. Phenolic groups like diarylheptanoids and flavonoids. While nonphenolics are terpenoids, especially sesqui- and monoterpenes. In this chapter, the group of sesquiterpene compounds from Curcuma comosa starts from the isolation technique, followed by the elucidation of the molecular structure, and their activity tests have been discussed.

Groundwater system is very vital to humanity and the ecosystem. Aquifers are determined based on the absence or presence of water table positioning, that is, confined, unconfined, leaky aquifers and fractured aquifers. The objective of this chapter is to discuss the characteristic and assessment of groundwater within the scope of vertical distribution of GW, types of the aquifer system, types of SW-GW interface, and SW-GW interaction at both local and regional scales. The properties of the aquifer depend on the physical characteristics of the materials (porosity, permeability, specific yield, specific storage, and hydraulic conductivities) which are determined by techniques like resistivity surveys and pumping tests followed by remote sensing and geographic information system for better information on the groundwater system. Furthermore, understanding the SW-GW interactions through available methods (seepage meter, heat tracer, and environmental tracer) is useful in watershed management, that is, risk management and assessment of the aquifer system.

It has always been a target to shorten and improve the healing process in medical field. Platelets with cytokines and growth factors in their structure have great importance on wound healing. Features of platelets gave the clinicians the idea of using platelet concentrates to promote the healing process. For this reason, many platelet-derived biomaterials have been tried in the medical field over the years. When approaching today, platelet concentrates have been found to be used medically, especially with the use of platelet rich plasmas (PRPs) and then platelet rich fibrins (PRFs). In particular, several studies conducted in recent years have revaled different blood concentrates. This chapter summarizes the develoment over time, properties and usage areas of blood concentrates in dentistry.

Published: October 2020

Hyperspectral imaging (HSI) is a technology able to measure information about the spectral reflectance or transmission of light from the surface. The spectral data, usually within the ultraviolet and infrared regions of the electromagnetic spectrum, provide information about the interaction between light and different materials within the image. This fact enables the identification of different materials based on such spectral information. In recent years, this technology is being actively explored for clinical applications. One of the most relevant challenges in medical HSI is the information extraction, where image processing methods are used to extract useful information for disease detection and diagnosis. In this chapter, we provide an overview of the information extraction techniques for HSI. First, we introduce the background of HSI, and the main motivations of its usage for medical applications. Second, we present information extraction techniques based on both light propagation models within tissue and machine learning approaches. Then, we survey the usage of such information extraction techniques in HSI biomedical research applications. Finally, we discuss the main advantages and disadvantages of the most commonly used image processing approaches and the current challenges in HSI information extraction techniques in clinical applications.
Anthocyanins: Promising Natural Compounds for Prevention and Treatment of Oral Squamous Cell Carcinoma
Authors: Pourshahidi Sara , Davari Mohaddeseh
Published: October 2020

Background: Oral squamous cell carcinoma (OSCC) is the most common oral cancer. In recent decades, numerous studies have focused on the effects of new herbal and natural bioactive substances or pharmaceutical products on different cancer types. Some investigations have shown that anthocyanins can inhibit carcinogenesis in various ways, and some others focused on the effects of anthocyanins on squamous cell carcinoma (SCC). Methods: An electronic search of the literature was carried out in PubMed, Web of Science, and Scopus databases using the keywords “anthocyanins” and “oral cancer” or “oral squamous cell carcinoma”. Articles relevant to our topic (except for review articles) were included in this study. Results: The reviewed articles showed the inhibitory and suppressive effects of anthocyanins on OSCC, which were exerted by inhibiting NF-κB, p-Akt/PI3k, and JAK/STAT3 pathways, the induction of caspase-1 and caspase-3 overexpression, pyroptosis, mitochondrial-mediated apoptosis, and reduction of expression and production of matrix metalloproteinases and urokinase-type plasminogen activator. Conclusions: Based on the results, the anti-proliferative and apoptotic effects of anthocyanins on OSCC were dominant. Their antimetastatic effect was also reported. Therefore, anthocyanins seem to be promising natural compounds for the prevention and treatment of OSCC. In vivo studies and clinical trials are recommended to further confirm these results.
Is Vision for Action Unconscious?
Authors: Wu Wayne ,   Journal of Philosophy Inc.
Published: October 2020

Empirical work and philosophical analysis have led to widespread acceptance that vision for action, served by the cortical dorsal stream, is unconscious. I argue that the empirical argument for this claim is unsound. That argument relies on subjects’ introspective reports. Yet on biological grounds, in light of the theory of primate cortical vision, introspection has no access to dorsal stream mediated visual states. It is wrongly assumed that introspective reports speak to absent phenomenology in the dorsal stream. In light of this, I consider a different conception of consciousness’s relation to agency in terms of access. While theoretical reasons suggest that the inaccessibility of the dorsal stream to conceptual report is evidence that it is unconscious, this position begs important questions about agency and consciousness. I propose a broader notion of access in respect of the guidance of intentional agency as the crucial link connecting agency to consciousness.
Socio-urban aspects of the pandemic crisis in Serbia
Authors: Božilović Jelena , Petković Jelena
Published: October 2020

The paper deals with the discussion of cities from a socio-ecological perspective, from the standpoint of health and quality of life from the time of the first industrialisation to the current social crisis. Rethinking the connection between health and life in the city in modern social theory has resulted in new constructive concepts of the city, and some ideas of such concepts in the current situation may be guidelines for the development of cities of the future. The second segment of the paper is based on the analysis of selected results of the broader empirical research conducted in 2020 by anonymous online survey and applying comparative-analytical and statistical methods. The respondents' views on the quality of life in the city and countryside at the time of the pandemic generally show that, despite the fact that the respondents evaluate the countryside more positively than the city, their attitude is such that minority of them agree with the fact that the experience with the pandemic will direct people to life outside cities in the future.
The coronavirus crisis as a world-historic event in the digital era
Authors: Tsekeris Charalambos , Zeri Persefoni
Published: October 2020

The world-historic event of the COVID-19 pandemic has once more confirmed that we live in a hyperconnected world society and that, nowadays, epidemics do not count as merely natural phenomena anymore. In such context, the present paper aims to interpret the complex relationship between the society and COVID-19, with emphasis on the role played by different forces in the field of information policy and public perceptions in general. For this reason, we elaborate on cultural factors, as well as on emotions like responsibility, trust, and fear during the crisis. We also focus on the dynamics of contemporary media in relation to public images of the pandemic, drawing upon relevant findings. Overall, this casts a fresh sociological and interdisciplinary light on the current pandemic as a relational process and a digital media-driven phenomenon.
