ABSTRACT

Meat 4.0 refers to the application the fourth industrial revolution (Industry 4.0) technologies in the meat sector. Industry 4.0 components, such as robotics, Internet of Things, Big Data, augmented reality, cybersecurity, and blockchain, have recently transformed many industrial and manufacturing sectors, including agri-food sectors, such as the meat industry. The need for digitalised and automated solutions throughout the whole food supply chain has increased remarkably during the COVID-19 pandemic. This review will introduce the concept of Meat 4.0, highlight its main enablers, and provide an updated overview of recent developments and applications of Industry 4.0 innovations and advanced techniques in digital transformation and process automation of the meat industry. A particular focus will be put on the role of Meat 4.0 enablers in meat processing, preservation and analyses of quality, safety and authenticity. Our literature review shows that Industry 4.0 has significant potential to improve the way meat is processed, preserved, and analysed, reduce food waste and loss, develop safe meat products of high quality, and prevent meat fraud. Despite the current challenges, growing literature shows that the meat sector can be highly automated using smart technologies, such as robots and smart sensors based on spectroscopy and imaging technology.

ABSTRACT

This study, in the two years since the beginning of the COVID-19 pandemic, reveals the most focused issues by the Turkish white goods suppliers regarding Industry 4.0 and the challenges encountered while engaging in Industry 4.0 practices. The data were obtained through a questionnaire form participated by the managers of 36 different companies that are members of the Turkish White Goods Suppliers Association. The collected data were classified, and it was found that the most focused issues of the companies were technology investments, ERP and MES, data collection, business processes, investment plans, organizational transformation, occupational health and safety, and participation in Industry 4.0-related events, respectively. Moreover, the most common challenges companies face concerning Industry 4.0 are related to the not being able to come together, finance, technology providers, postponement of investment plans, and loss of employees. On the other hand, 16% of the participating companies stated that they did not encounter any difficulties. © 2022 IEEE.

ABSTRACT

A 21-year-old woman presented with a 5-month history of swollen, painful, purple discolouration of her toes and fingers, which began 6 weeks after COVID-19 infection. This was refractory to ibuprofen and clobetasol 0.05% w/w ointment. She reported no other associated symptoms. On examination she had erythematous mottling of the tips of the toes and nail folds of the right foot and sausage-shaped deformities of the left second and fourth toes, consistent with dactylitis. Her blood work-up for COVID toes revealed a raised serum angiotensin- converting enzyme (ACE) level (64 U L-1) with no other abnormalities. Her chest X-ray was unremarkable. Plain radiographs of the feet showed soft tissue swelling and lacelike bony appearances with discrete areas of lucency, particularly affecting the middle phalanx of the left second toe. This pattern has been described in sarcoid arthropathy. Magnetic resonance imaging of the left foot demonstrated features of inflammatory arthropathy, including subarticular bone marrow oedema, periarticular soft tissue oedema and flexor tendon tenosynovitis. The findings were consistent with COVID toes;however, some features of the dactylitis extended beyond the expected presentation of a vascular manifestation of COVID-19. She displayed overlap features seen in sarcoid-related pathologies, including raised ACE levels and a lace-like bony appearance. We believe this to be a sarcoid-like immune reaction to COVID-19 presenting with COVID toes and dactylitis. A sarcoid-like immune reaction to COVID-19 with granulomatous skin lesions rather than dactylitis has been reported. Viral infections are a documented trigger for sarcoid- like immune reactions. This case suggests that COVID-19 can trigger sarcoid-like immune reactions, albeit with a more discrete presentation.

ABSTRACT

Our lives are still not back to normal because of the novel coronavirus epidemic, and people around the world are looking for ways to compensate for the limited experience. The global buzz around Metaverse can also be seen as a concern to upgrade the experience, and the trend toward virtual world interaction is unstoppable, in the future, the boundary between virtual world and real world will be a direction of further exploration in the field of interaction design. If the meta-universe can be developed into a future society, it should not be viewed as a mere technical question. Whether this future is worthy of human pursuit requires us to think more. So based on the future doomed to borderline ambiguous social forms, the establishment of a new order first needs to clarify the virtual world and the real world and the relationship between the difference. This paper critically interprets the concept of meta-cosmic society, and discusses the thinking of the boundary definition in the future context, it is hoped that this discussion will provide a valuable perspective for interaction design to be integrated into the new experience pattern in the future. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

ABSTRACT

In this study, we aim to determine how the global turmoil of COVID-19 acts as a catalyst for global transformations. After examining recent sociological and economic implications of this pandemic crisis, we analyse specific theoretical frameworks that can be helpful to illuminate some of the features of the current global evolutionary readjustment from an elliptic point of view. These theoretical approaches are the techno-economic paradigm shift, the notion of ‘endless transition’, the fourth industrial revolution analytical framework, and the approach of ‘new globalisation’. Finally, we identify that the current pandemic crisis has caused a ‘stroke’ to the world economy that accelerates developments and radically intensifies the pre-existing challenges. Especially for the less developed, stable, and resilient socio-economic systems and organisations (the case study of Cyprus is examined, respectively), we conclude that their survival and growth depends primarily upon their potential for adaptiveness, innovation, and on building efficient change management aptitudes and mechanisms. © 2021, University of Nicosia.

ABSTRACT

BACKGROUND & AIMS: Liver transplant recipients (LTR) show a decreased immune response after two SARS-CoV-2 vaccinations compared to healthy controls (HC). Here, we investigated the immunogenicity of additional vaccinations. METHODS: In this prospective study, humoral (anti-S RBD) and cellular (Interferon-gamma release assay (IGRA)) immune responses were determined after mRNA-based SARS-CoV-2 vaccination in 106 LTR after a third, and in 36 LTR after a fourth vaccination. Patients with anti-S RBD antibody levels >0.8 AU/mL after vaccination were defined as responders. RESULTS: After three vaccinations, 92% (97/106) of LTR compared to 100% (28/28) of HC were responders. However, the antibody titer of LTR was lower compared to HC (1891.0 vs. 21857.0 AU/mL, p<0.001). Between a second and third vaccination (n=75) the median antibody level increased 67-fold in LTR. In patients seronegative after two vaccinations, a third dose induced seroconversion in 76% (19/25), while all HC were already seropositive after two vaccinations. A spike-specific T-cell response was detected in 72% (28/39) after a third compared to 32% (11/34) after a second vaccination. Independent risk factors for a low antibody response (anti-S RBD <100 AU/mL) were first vaccination within the first year after LT (OR: 8.00, p=0.023), eGFR <45 mL/min (OR: 4.72, p=0.006), and low lymphocyte counts (OR: 5.02, p=0.008). A fourth vaccination induced a 9-fold increase in the median antibody level and seroconversion in 60% (3/5) of previous non-responders. CONCLUSION: A third and fourth SARS-CoV-2 vaccination effectively increases the humoral and cellular immune response of LTR, but to a lesser extent than in HC. A fourth vaccination should be generally considered in LTR.

ABSTRACT

The COVID-19 pandemic since 2020 created havoc across the globe. This led to the establishment of effective vaccines to mitigate the virus. Several vaccines are developed to create immunity amongst the population. However, due to emerging variants of SARS-CoV-2, despite a double dose of vaccines, people have still infected that termed vaccine breakthrough infection. This paper aims to highlight the recent re-surging massive outbreak of COVID-19 in China despite mass vaccination and, discuss the issue of vaccine breakthrough infection, possible causes, and recommendations to enhance immunity and curb the transmission.

ABSTRACT

There is scarce information on seroconversion and adverse events after immunization (AEFI) with the fourth dose of BNT162b2. Our aim was to correlate the magnitude of the antibody response to this vaccination regimen in terms of clinical conditions and AEFI. This was an observational pilot study in which SARS-CoV-2 S1-S2 IgG antibodies titers were measured 21-28 days after the first and second dose, three months after the second dose, 1-7 and 21-28 days after the third dose, before the fourth dose, and 21-28 days after the fourth dose. We recruited 112 subjects in a hospital in Mexico, 74% women, with an average age of 43 (SD 9) years. After the first dose, subjects had a median IgG AU/mL (IQR) of 122 (1904) that increased to 1875 (2095), 3020 (2330), and 4230 (3393) 21-28 days after the second, third, and fourth doses, respectively (p < 0.01). The number (%) who experienced any AEFI between the first and fourth doses was 90 (80.4), 89 (79), 65 (58), and 69 (61.5), respectively (p < 0.001). After the fourth dose, the most frequent of AEFI was pain at the injection site (87%). There was a correlation between AEFI and gender after the fourth dose, as well as with antibody levels (p < 0.05). During the Omicron outbreak, six (5.3%) had mild COVID-19 for 8-28 days after the fourth dose. The median increase in S1/S2 IgG was 30.8-fold after the fourth BNT162b2 dose when compared with the first dose and caused mild AEFI.

ABSTRACT

This study assessed the influence of the COVID-19 pandemic in motivating digital transformation in the education sector in Zimbabwe. The study tracked the rate at which the Fourth Industrial Revolution (4IR) tools were used by various institutions during the COVID-19 lockdown. Data were obtained from secondary sources. The findings are that, in Zimbabwe, during the lockdown, a variety of 4IR tools were unleashed from primary education to higher and tertiary education where educational activities switched to remote (online) learning. These observations reflect that Zimbabwe generally has some elements of excellence to drive the education sector into the 4IR, which has the potential to increase access. Access to education, particularly at a higher education level, has always been a challenge due to a limited number of spaces available. The pandemic has presented an opportunity to assess successes and failures of deployed technologies, costs associated with them, and scaling these technologies to improve access.

ABSTRACT

Objective: NA Background: The etiology of MOGAD post-COVID-19 infection is not well understood and there are limited publications describing cases in pediatric patients. Here we report a case of a 14-year-old male with MOG antibody positive ADEM (Acute Disseminated Encephalomyelitis) and positive COVID-19 PCR. Design/Methods: NA Results: The patient presented to our hospital in December of 2020 with acute onset of ataxia and lower extremity weakness. His exam was pertinent for mild and symmetric weakness in bilateral hip flexors, dysmetria with ataxic gait, as well as bilateral patellar and ankle hyporeflexia. MRI brain showed symmetric areas of T2 signal hyperintensity, predominantly adjacent to the fourth ventricle as well as the peri-insular and frontal regions. MRI of the lumbosacral spine demonstrated T2 signal hyperintensity within the conus medullaris without enhancement. CSF studies revealed an increased white blood cell count of 74 (90% lymphocyte), elevated protein of 51, elevated kappa free light chain (0.12) and positive oligoclonal bands (3). He was also found to be serum anti-MOG antibody positive (1:100) and COVID-19 positive (PCR). He received 1000 mg of intravenous methylprednisolone daily for 5 days and 2 g/kg IVIG. He was subsequently placed on a 6 week taper of oral prednisone. 2 months after his initial presentation, his neurologic symptoms have completely resolved, and he has been asymptomatic since. Repeat MRI brain 4 months later showed improvement in his multifocal supratentorial FLAIR signal abnormalities. Conclusions: Here we describe a case of a 14-year-old male with MOGAD post-COVID-19, with complete resolution of his symptoms after high dose corticosteroid and IVIG treatment.

ABSTRACT

The definition of work has been significantly impacted by the rise of the open talent economy and a greater focus on outcome-based work design. These changes have led to a reconceptualisation of the psychological contract as organisations seek new ways of work to achieve sustainable success, whilst employees are expecting work design as part of an attractive employee value proposition. With the acceleration of the changing world of work it has become imperative to explore how organisations respond to the changing psychological contract. The chapter provides a high-level and speculative perspective on the trends that will impact the world of work over the coming years and positions these trends as changes to what we refer to as 'work'.

ABSTRACT

Purpose Studies have shown that managing household solid waste from low-cost housing in urban and sub-urban communities is challenging, especially in developing countries and COVID-19 era. Previous research proved that the fourth industrial revolution (4IR) technologies could be engaged to improve urban public services such as household solid waste. Thus, the study investigated 4IR role in improving low-cost housing solid waste management (LCHSWM) in the COVID-19 era across Malaysia's cities. Design/methodology/approach The researchers selected four Malaysian cities (Pulau Pinang, Kuala Lumpur, Kuching and Putrajaya) to achieve the study's objectives via a qualitative research design. The study engaged forty experts through semi-structured virtual interviews. A thematic approach was used to analyse the collected data. Findings Findings identified initial high implementation and maintenance costs, unwillingness to accept change, inadequate knowledge and skilled personnel to manage the operation, amongst others, as the perceived challenges facing 4IR technologies in managing low-cost housing solid waste across Malaysian cities in the COVID-19 era. Also, the study proffered measures to improve 4IR technologies usage. Research limitations/implications This paper is limited to the perceived contributory challenges and proffered measures to improve 4IR technologies usage in managing LCHSW across Malaysian cities in the COVID-19 era. Practical implications Proffered measures will stir policymakers and the political class (city councils) to start thinking of an all-inclusive approach to addressing the issue of LCHSW in the 21st century. As part of the practical implications, the possible outcome might enhance collaboration between the public and private sectors to better service delivery to mitigate environmental degradation. Originality/value As revealed in the review, there is a paucity of literature regarding digital technology's roles in mitigating LCHSW across Malaysian cities in the COVID-19 era.

ABSTRACT

The COVID-19 pandemic hit Afghanistan at a time when the country was most vulnerable, with a fragile healthcare system and unable to contain the disease, and meet the needs of the vulnerable people. The country has gone through four waves of the disease thus far. An analysis of the COVID-19 cases reported by the District Health Information Software-2 shows that the fourth wave has just passed in March 2022. With the resurgence of the COVID-19 cases in other countries, it is likely that the next wave might not be too far. Challenges such as the lack or insufficiency of donor funds, unstable political situation, inadequate healthcare services, insufficient healthcare workers and diagnostic capacity, illiteracy of people, poor economy and shortage of the COVID-19 vaccine are greatly threatening the nation. The de facto authority does not seem to have a clear plan to fight against the pandemic. Therefore, the international community, civil societies, healthcare workers and other stakeholders should stay alert and combine their efforts to rescue an already plagued nation. Fortunately, many COVID-19 hospitals and laboratories have resumed their activities with the funds coming from international donors. However, to combat the infection in the long term, there seems to be a great need to integrate the COVID-19 services in the existing package of healthcare services, ie the Sehatmandi project. Moreover, awareness campaigns should be continued to keep the most vulnerable groups safe and protected. Vaccination services also need to be speeded up to have a significant portion of people immunized. Public willingness towards getting the vaccine should be increased through awareness campaigns mostly conducted by social media volunteers and healthcare workers.

ABSTRACT

Background: There is no evidence to date on immunogenic response among individuals who participated in clinical trials of COVID-19 experimental vaccines redirected to standard national vaccination regimens. Methods: This multicentre, prospective controlled cohort study included subjects who received a COVID-19 experimental vaccine (CVnCoV)(test group, TG) - and unvaccinated subjects (control group, CG), selected among individuals to be vaccinated according to the Spanish vaccination program. All study subjects received BNT162b2 as a standard national vaccination schedule, except 8 (from CG) who received mRNA-1273 and were excluded from immunogenicity analyses. Anti-RBD antibodies level and neutralising titres (NT50) against G614, Beta, Mu, Delta and Omicron variants were analysed. Reactogenicity was also assessed. Findings: 130 participants (TG:92; CG:38) completed standard vaccination. In TG, median (IQR) of anti-RBD antibodies after first BNT162b2 dose were 10740·0 BAU/mL (4466·0-12500) compared to 29·8 BAU/mL (14·5-47·8) in CG (p <0·0001). Median NT50 (IQR) of G614 was 2674·0 (1865·0-3997·0) in TG and 63·0 (16·0-123·1) in CG (p <0·0001). After second BNT162b2 dose, anti-RBD levels increased to ≥12500 BAU/mL (11625·0-12500) in TG compared to 1859·0 BAU/mL (915·4-3820·0) in CG (p <0·0001). NT50 was 2626·5 (1756·0-5472·0) and 850·4 (525·1-1608·0), respectively (p <0·0001). Variant-specific (Beta, Mu, Omicron) response was also assessed. Most frequent adverse reactions were headache, myalgia, and local pain. No severe AEs were reported. Interpretation: Heterologous BNT162b2 as third and fourth doses in previously suboptimal immunized individuals elicit stronger immune response than that obtained with two doses of BNT162b2. This apparent benefit was also observed in variant-specific response. No safety concerns arose. Funding: Partly funded by the Institute of Health Carlos-III and COVID-19 Fund, co-financed by the European Regional Development Fund (FEDER) "A way to make Europe".

ABSTRACT

Orientation: Regulations for the industrial psychology profession state that short-term counselling may be provided to employees in the workplace. It is therefore necessary to be equipped with the required skills to assist employees especially to cope in the changing world of work. Research purpose: The general objective of this research study was to explore the role of industrial psychologists as workplace counsellors in the changing world of work. Motivation for the study: In light of recent changes in the world due to coronavirus disease 2019 (COVID-19), there seems to be a strong motivation to explore the importance of workplace counselling with regard to the changing nature of work. Research approach/design and method: A qualitative descriptive research strategy was utilised, with homogeneous sampling of 22 industrial psychology practitioners ( n = 22). Main findings: The results showed that workplace counselling as an intervention provides the support employees need to adapt to changes in the workplace. Technological advances have a major impact on the manner in which people work, and therefore employees need the support to cope with these changes. Counselling from an industrial psychology practitioner could provide this type of support. Practical/managerial implications: Industrial psychology practitioners in the role of counsellors in an organisation play a major part in helping employees with accepting and coping with the changes and challenges presented by the implications of the Fourth Industrial Revolution (4IR). Contribution/value-add: This study could contribute by providing organisations with valuable feedback on how to address challenges presented by the changing nature of work, specifically the importance of the role of workplace counselling provided by industrial psychology practitioners.

ABSTRACT

BACKGROUND: Waning vaccine-immunity and an increased incidence of COVID-19 during the Omicron outbreak led the Israeli Ministry of Health to recommend a fourth dose of BNT162b2 for high-risk individuals. This study assessed the effect of that dose for hospitalized patients with severe/critical, breakthrough COVID-19. METHODS: In this multi-center retrospective cohort study of hospitalized adults with severe/critical COVID-19 in Israel, from 01/15/2022-01/31/2022, cases were divided according to the number of vaccinations received. Poor outcome was defined as mechanical ventilation or in-hospital death, and was compared between 3- and 4-dose vaccinees using logistic regression. RESULTS: Included were 1,049 patients, median age 80 years (IQR 69-87), 51% males. Among them, 394 were unvaccinated, 386 had received 3 doses and 88 4 doses. The 3-dose group was older, had more males and immunosuppression, but with similar outcomes, 49% vs. 51% compared to unvaccinated patients (p = 0.72). Patients after 4 doses were similarly older and immunosuppressed, but had better outcomes compared to unvaccinated patients, 34% vs. 51% (p < 0.01). We examined independent predictors for poor outcome in patients with either 3 or 4 doses, received a median of 161 (IQR 147-168) or 14 (IQR 10-18) days before diagnosis, respectively. Receipt of the fourth dose was associated with protection: OR 0.51 (95%CI 0.3-0.87), as was Remdesivir OR 0.65 (95%CI 0.44-0.96). Male sex, chronic renal failure and dementia were associated with poor outcomes. CONCLUSIONS: Among hospitalized patients with severe/critical breakthrough COVID-19, a recent fourth dose was associated with significant protection against mechanical ventilation or death, compared to three doses.

ABSTRACT

Health systems were severely strained at the start of the COVID-19 pandemic, where the demand for personal protection equipment (PPE) could not be met. The challenge faced by many countries was how to innovate quickly to create PPE and other needed solutions. The subsequent research gap identified was a lack of practical insights on how to support such novel technology adoption, particularly those that stem from Industry 4.0 (I4.0) within a developing world context. To address this previous literature on I4.0 technology, the role of innovation environments and theoretical principles of technology adoption was reviewed. A practical case from an academic makerspace based in a South African university was then assessed. It was selected due to its direct role in rapid solutions development of PPE using additive manufacturing (AM) until such a time that manufacturers could set up production on a larger scale. It was found that AM and other novel technologies have facilitated innovative solutions to address the significant impacts of the pandemic. Key to which were practices identified of an innovation environment that supported early-stage adoption of AM to achieve this even in a developing country context. The findings imply that innovation environments offer an agile platform to leverage innovation by streamlining certain critical success factors of I4.0 technology adoption, which is presented in a model. However, individual skills developed by such environments to enhance innovation capabilities within this paradigm require further research.

ABSTRACT

This study investigated the essentials for institutionalizing technologies for teaching and learning across the three types of universities in South Africa. This was with a view to determining the skills required for teaching and learning in the 4IR era. In order to obtain the data needed for the study, cross-sectional survey design was employed and online interview was conducted on Microsoft Teams and Zoom with the participants to elicit first-hand information. The population consisted of all the Executive Deans/Deans of Faculties in twenty-six (26) South African Universities. A total of twenty-two (22) Universities were purposefully selected to allow fair representation to make the findings generalizable. Seventy (70) Executive Deans/Deans participated in the online data collection via Microsoft Teams and Zoom. Content analysis and descriptive statistics were employed for analyzing data. Findings revealed that the universities in the Republic deployed fifty-seven different technologies to facilitate their teaching and learning activities, and teaching platforms had been supplemented with new technologies such as WhatsApp, Zoom, and MS Teams. Although resistance had been experienced in the past, the teaching staff is competent to moderately competent in the use of existing technologies for teaching because most faculties had provided training in an on-going basis. Improvements in the standard and quality of teaching and learning were observed with the aid of emerging technologies. The study concludes that while Universities are settled to adopt blended learning as the strategy to implement the convergence between human and machines in the era of the fourth industrial revolution, there is a need to have a national policy in place that deals with funding (special grant) to plug the gap on the digital divide.

ABSTRACT

Purpose>The Fourth Industrial Revolution (4IR) and the Coronavirus Disease 2019 (COVID-19) have challenged the academic libraries system with a paradigm shift that has never been experienced before. This article highlights how the library staff offered support with the 4IR to the remote during the COVID-19 era;to ensure that the provision of information resources does not halt because of the imposed lockdown COVID-19 regulations. The purpose of this study was to examine the library staff support with 4IR's application to provide information resources to remote clients during the COVID-19 library services.Design/methodology/approach>The study was anchored by the positivism research paradigm and used a quantitative research approach. Microsoft Form was used to design an online questionnaire to collect data from the library staff working in a distance education environment in Gauteng Province of South Africa. The collected data were analyzed using the Statistical Package for the Social Sciences (SPSS).Findings>The findings discovered that the library staff was keen on job innovation;however, the COVID-19 restrictions were a major cause for the library staff not to provide information resources to remote clients effectively.Research limitations/implications>The 4IR has both positive and negative effects on the library staff and the remote clients. To ensure that academic libraries fully embrace the 4IR;it is imperative to examine how the remote clients affected by digital divide can benefit from this revolution since they do not have access to adequate gadgets such as laptops/personal computers/tablets/smartphone/iPods and data for Internet connection.Practical implications>This study contributed to the Library and Information Science's (LIS) field by adding value to the knowledge base concerning how the library staff working in academic libraries operating in a distance education environment in Gauteng Province of South Africa offered support to the remote clients during the COVID-19 pandemic that impacted the drastic adoption of the 4IR.Social implications>Stakeholders, library management and policymakers gained insight to revisit the existing library staff support regarding mentoring, coaching training remote clients on how to access and download online information resources. This is inspired by the fact that COVID-19 significantly influenced library services' value for knowledge by facilitating policy changes and aligning with 4IR.Originality/value>The study greatly influences policymakers and information practitioners to mobilize new methods of library staff support.

ABSTRACT

Currently, molecular hydrogen treatment has the potential to manage the Corona Virus disease (COVID-19) and pandemic based on its anti-inflammatory, apoptosis-resistance, antioxidant, and hormone-regulating properties. Antioxidant properties are beneficial in both animal and human diseases. In agricultural sciences, molecular hydrogen is used to postpone postharvest ripening and senescence in fruits. However, studies on flower senescence are limited to the application of hydrogen molecules during floral preharvest and postharvest. Fortunately, improved tools involving molecular hydrogen can potentially improve postharvest products and storage. We also discuss the benefits and drawbacks of molecular hydrogen in floral preharvest and postharvest. This review provides an overview of molecular hydrogen solutions for floral preservative storage.
