ABSTRACT
The use of plastic bottles has become a significant environmental concern, and recycling them has become a priority. Small and medium-sized recycling companies must collect and categorize large volumes of plastic bottles and sell them to larger recycling firms, a process that is time-consuming, costly, and labor-intensive. This manual sorting process can pose health risks, particularly during the COVID-19 pandemic, and can affect worker productivity. To address these issues, this study proposes the development of an automated conveyor belt system that can rapidly and accurately separate plastic bottles by type. The system utilizes an opaque and transparent plastic bottle separation platform, which saves time, cost, and manpower. This system design provides recycling SMEs with a competitive advantage by serving as a practical application model and a prototype with an easy-to-use concept. Key tools employed in this research include product design development (PDD), Kansei engineering, manufacturing process design, controlling system, and fault tree analysis (FTA). The light sensors are critical components in the separation process, detecting the opacity or transparency of the bottles' surfaces. The proposed prototype's reliability will be assessed by FTA, which considers all potential failures. This study contributes to the body of knowledge surrounding the integration of conveyor systems and provides valuable information for businesses seeking to optimize their sorting processes. The guidelines developed in this study can serve as a starting point for further research on the integration of conveyors in waste sorting plants. © 2013 IEEE.
ABSTRACT
The word Metaverse has influenced many sectors such as healthcare, education, retail and manufacturing and few more industries are there which will be impacted by 2026 as per the research conducted by Gartner. The word 'Metaverse' especially in education sector came into existence after the COVID-19 epidemic when the humanity were forced to think about the new methodology of educating and teaching. This ecosphere is the combination of technologies which enables multimodal interactions with artificial environment, electronic library and people such as Virtual Reality (VR) and Augmented Reality (AR). It is believed that metaverse will improve collaboration, training process will be enhanced and most importantly it will create a happier workplace. This is only the reason that many corporate giants like Nvidia, facebook, apple, epic Games and companies has shifted towards this pedagogical ecosystem. This technology has the potential which enables absolute incorporating user conversation in actual-time and compelling interactivity with digital artifact. In this paper, we are addressing metaverse in education along with a detailed framework of metaverse in education. It includes a comparative study of conventional education, online education and metaverse education based on parameters like place of learning, resources used, teaching methodology, learning experience, learning target and learning assessment. Competency based education, energize student and positive attitude towards learning. The various challenges of the metaverse in educational sector are also debated. This paper will help the researcher's fraternity to get a deeper insight along with a clear perception of this ecosystem in education. © 2023 IEEE.
ABSTRACT
This paper attempts to elucidate Vietnam's strategies and policies for fostering digital transformation. Vietnam has made some progress in the digital transformation of its economy but there are challenges to achieving further progress. Business enterprises struggle to adopt digital technologies due to technical, financial and regulatory constraints. These constraints include conversion costs, internal infrastructure resources, data leakages and ineffective regulations. The government has provided support for the digital transformation of enterprises through improvements in its å framework for the digital economy, promotion of science and technology, taxation regime and SME assistance. The government should undertake further legal reforms to support digital transformation, strengthen digital human resources and enhance e-government capabilities.
ABSTRACT
To cope with the digital transition exacerbated by the COVID-19 pandemic, managers of manufacturing small and medium enterprises (SMEs) need to adopt innovative practices to face uncertain scenarios and create long-term value, identified as transformational entrepreneurship practices. Among emerging digital technologies, digital platforms are shaping and outgrowing the e-commerce channel representing a potential opportunity for manufacturing SMEs to embrace digital transformation. Drawing on affordance theory, this research uses a mixed method approach to investigate how manufacturing SMEs' e-commerce commitment and digital platform adoption stimulate the actualization of three e-commerce affordances: consumer knowledge generation, internationalization, and customer diversification. Based on survey responses from 165 manufacturing SME managers, we find that direct selling through owned websites actualizes consumer knowledge generation and internationalization, indirect selling actualizes customer diversification and internationalization, and agency selling through third-party platforms actualizes all three affordances. The relationship between e-commerce commitment and ecommerce performance is mediated by consumer knowledge generation and internationalization but not by customer diversification. A fsQCA analysis outlines seven configurations actualizing these e-commerce affordances by pairing different ecommerce approaches with degrees of e-commerce commitment. Finally, an analysis of open-ended questions from 24 respondents complements the study and deeply interprets the seven unique configurations outlined. © 2023 The Authors

ABSTRACT
Fibre-reinforced plastic (FRP) materials are attracting growing interest because of their high specific mechanical properties. These characteristics, in addition to a high level of tailorability and design of freedom, make them attractive for marine, aerospace, automotive, sports and energy applications. However, the large use of this class of material dramatically increases the amount of waste that derives from end-of-life products and offcuts generated during the manufacturing processes. In this context, especially when thermosetting matrices are considered, the need to deeply study the recycling process of FRPs is an open topic both in academic and industrial research. This review aims to present the current state of the art of the most affirmed recycling technologies used for polymeric composites commonly used in industrial applications, such as carbon and glass FRPs. Each recycling method (i.e., chemical, thermal and mechanical) was analysed in terms of technological solutions and process parameters required for matrix dissolution and fibre recovery, showing their advantages, drawbacks, applications and properties of the recycled composites. Therefore, the aim of this review is to offer an extensive overview of the recycling process of polymeric composite materials, which is useful to academic and industrial researchers that work on this topic.
ABSTRACT
The furniture industry is one of the strategic industries in Serbia, with about 30,000 employees. The subject of research in this paper was the furniture market in three selected regions in Serbia with the aim to consider the influence of certain factors on the demand for furniture during the COVID-19 pandemic, as follows: prices, quality, payment terms, brands, promotions, terms of purchase, frequency of furniture purchase, assortment, and online shopping. The methods used for the research included field research, surveys and analysis of the obtained data. The sample size included 210 respondents who were selected by random sampling method. When it comes to the impact of the COVID-19 pandemic, research shows that it did not significantly influence consumers' decision to buy furniture. Preference is given to domestic producers, both because of the availability of products and because of the more affordable price. When it comes to quality of furniture, the research showed that the 63% are satisfied with the ratio of price and quality, as well as the range offered on the market. The terms of payment are satisfactory, with the 58% customers opting for cash payments. On the other hand, the choice of the manufacturer is based on previous positive experience or recommendation, while going to the salon is the choice of 92% customers, compared to online shopping (8%). The conducted research is important for producers, distributors, and traders of furniture, as well as for the academic community because, for the first time, research was conducted on this topic in Serbia. © 2022 15th International Scientific Conference WoodEMA 2022 - Crisis Management and Safety Foresight in Forest-Based Sector and SMES Operating in the Global Environment.

ABSTRACT
The world is facing dual challenges of generating an economic recovery from the COVID-19 crisis, and transitioning to a low-carbon economy to tackle climate change. Strongly interrelated global challenges will require an integrated and coordinated response by all countries to manage the risk and lay the foundation for building back better. As the world's biggest emitter and the second-largest economy, China is a very important player in international collaboration and coordination in climate action. Against this backdrop, this paper looks into the increasingly crucial role that China is playing in global climate action, especially focusing on three aspects: China's domestic and foreign policymaking for the energy transition;its role in promoting multilateralism and international collaboration on building a sustainable world;and how it could accelerate climate action and diplomacy through research, development and innovation. In the critical decade of the 2020s, China has a great opportunity to further transform and upgrade its energy and industrial structures, promote research, development and the application of green and low-carbon technologies and intensify international climate cooperation on climate change. China should aim to be at the forefront of raising climate ambition and accelerating climate action for a sustainable and more equitable world. © 2023 IOP Publishing Ltd.
ABSTRACT
In the wake of the pandemic Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) we can look at many aspects of the global response, including social, scientific, and governmental. Current research in the areas of vaccine development and manufacturing find the process of developing a new vaccine takes an especially long time and is unresponsive. Understanding the factors that influence responsiveness can help organizations be better prepared to address the needs of society should another pandemic strike. Responsiveness can be linked to product, process, and volume. The vaccine development and manufacturing process historically takes years to reach distribution for public use. In the face of potential pandemics, learning from SARS-CoV-2 vaccine responsiveness will provide essential information for future decision making. This paper will propose a method to quantify and evaluate the responsiveness of manufacturing processes and vaccine development within the vaccine industry by considering various elements of an organization's vaccine development and supply chain process. We created a model to evaluate characteristics within the supply chain for vaccine delivery. The model can be used to better understand an organization's strengths and weaknesses in their supply chain. In turn, an organization can be better prepared to act swiftly against a future pandemic.

ABSTRACT
Science and manufacturing have always been a generator and conduit of innovations in every field of human life. The innovations are of both fundamental and purely applied nature. The first environment for testing these innovations is the internal firm's educational system. In this regard, the last two years circumstances around the pandemic of COVID-19 served as a catalyst for the training in companies to adopt contemporary, interactive and attractive methods of training processes. Of course, some of these methods have been used in the pre-pandemic environment, but they have not been widespread. This confirms the rule related to a crisis management, namely that any crisis must be seen not only as a threat, but also as an opportunity to master new approaches and to show their effectiveness in practice. The aim of this paper is to focus on the possibilities of using virtual reality in training employees in forest-based SMEs such as specific manufacturing procedures, healthy work condition, organization of manufacturing etc. A number of research methods will be used. These will include: literature research, retrospective analysis, method of comparison etc. © 2022 15th International Scientific Conference WoodEMA 2022 - Crisis Management and Safety Foresight in Forest-Based Sector and SMES Operating in the Global Environment.

ABSTRACT
Halliburton uses the term "local content" to describe programs to develop and use local resources in providing our services in that host country. Local content requirements vary by country, but commonly include providing employment opportunities to local citizens, procurement of goods and services from within the country, manufacturing and value addition through partnerships with and development of local entities, training programs to develop the technical skills of local individuals and businesses, and carry out research and development for finding indigenous alternates of imported materials. In almost all cases, local content requirements are mandated by the laws of the countries where we operate. Adhering to and improving local content is an important part of Halliburton's commitment to support the countries in which it operates and it also brings benefits for both Halliburton and local communities. In this paper, we share a case study of how Halliburton carried out the process of localizing chemical manufacturing in Saudi Arabia, the steps taken, and support extended in developing the local suppliers. Meeting local content requirements requires precise collaboration and communication between regional and country management teams, compliance with host country laws and regulations, adherence to Halliburton company policies, and meeting the quality standards the National Operating Company which is the end user in most cases. The methodology for achieving effective localization results started with setting the right strategy and putting challenging but achievable targets. This localization initiative exemplifies company efforts to create value in every aspect of the company's business through the In-Kingdom Total Value Add (iktva) program mandated by the national operating company in the country. Having a local source of manufacturing and supply chain mitigates any disruptions like the one we saw during COVID 19 whereby the movement across borders was partially closed and supply chain globally was disrupted. Any local souring effectively diminishes the impact of any such disruptions. This initiative considered more than 50 Halliburton commercial chemical products and resulted in more than 10 successful replacements. Halliburton was able to export three products to company's operations outside Saudi Arabia. Partnering with Saudi Aramco, chamber of commerce and local manufacturers and suppliers in this program will drive additional domestic value creation to support a rapidly changing economic environment and foster future prosperity.

ABSTRACT
As the healthcare response to the COVID-19 pandemic continues, providing enhanced protection to frontline healthcare personnel exposed to aerosolized infectious material is essential. The rapid spread of the COVID-19 virus across the globe in early 2020 generated an overwhelming surge in demand for effective personal protective equipment (PPE), in particular, passive personal respirators (PPR). Global manufacturing of PPR was limited, and research and development of improved respirators were restricted by the availability of accredited laboratories for timely testing at the peak of the pandemic. The authors have described a clinical method of safety and efficacy testing of a new PPR, the TopBioShield, using portable capnography for the measurement of end-tidal pCO2 (ETCO2) and bedside pulse oximetry to measure oxygen saturation (SpO2), respiratory rate (RR), and heart rate (HR) in healthy volunteers to overcome shortages of clinical testing capabilities during the height of the pandemic. Twenty-eight volunteers with a median age of 41 years (range 16–71) representing all 10 subgroups of head/face size were included. Only one participant asked to withdraw due to a feeling of claustrophobia after 30 min. Clinical monitoring while wearing TopBioShield revealed ETCO2, SpO2, respiratory rate, and heart rate measurements were within normal limits in all the subjects throughout the experiment. Bedside clinical monitoring is effective in demonstrating the physiological safety of PPR and is an important alternative to conventional mannequin testing. In this study all measured values over a 90-min experiment period were within normal limits, demonstrating the effectiveness of TopBioShield in preventing CO2 retention. Clinical testing methods must adhere to the highest standards and are essential during times of shortage. © 2023, The Institution of Engineers (India).
ABSTRACT
After the COVID-19 pandemic has spread throughout the world, many research institutions and industrial organizations are putting great efforts into producing environmentally friendly solutions for the transportation sector. This paper presents a newly developed combined solid oxide fuel cell system with a turbofan engine that can use five alternative fuels, such as dimethyl ether, methanol, hydrogen, methane, and ethanol, with different blending ratios to form five fuel blends. The proposed system is studied in this paper using exergoenvironmental analysis (which is known as environmental impact assessment by exergy) in order to quantify and evaluate the environmental impact. The combined turbofan has an exergetic efficiency of 82%, with total fuel and product exergy rates of 905 and 743 MW, respectively. The total environmental impact caused by emissions and exergy destructions has a range of 4000 to 9000 Pt/h for all the fuel blends. The specific exergoenvironmental impact values of electricity production vary from about 3 to 8 mPt/MJ for solid oxide fuel cells and 10 to 25 mPt/MJ for the three turbines. The exergoenvironmental impact of the thrust force is a minimum of 34 Pt/(h.kN) for the RF1 fuel and a maximum of 87 Pt/(h.kN) for the RF4 fuel. © 2022
ABSTRACT
Humanity has faced many crises in the past, such as pandemics, wars, and economic crises, and other crises are certain to come in the future;however, emerging technologies have a role to play in improving companies' resilience in the face of such crises. The coronavirus (COVID-19) pandemic has led to human, technological, and managerial constraints for manufacturing companies due to scarce resources or supply chain (SC) disruptions. The research goal of this paper is to investigate whether Industry 4.0 implementation improved companies' resilience and whether companies' performance maintained stability during the COVID-19 outbreak. Composite-based structural equation modeling is applied to analyse data collected from 207 manufacturing companies. The theoretical model is grounded in the Practice-Based View (PBV) theory. The research findings show that operational responses based on Industry 4.0, smart manufacturing practices, and smart capabilities enable manufacturers to build resilience and quickly mitigate performance loss in times of global crisis. Therefore, the results demonstrate that Industry 4.0 implementation provides resilience for companies through flexibility, reliability, robustness, and responsiveness. The main practical implication of this study is to support managers in achieving manufacturing performance stability during disrupted times, such as the COVID-19 crisis, using Industry 4.0 approaches to make their companies more resilient and prepared to face future challenges and crises. © 2022 Elsevier B.V.
ABSTRACT
The CO2 emission is enhancing drastically because of the continuous emission from industries and transport sector. Although the CO2 emission had decreased in the first half of 2020 by 8.8% due to COVID-19 restrictions however, it is again on the rise and it might exceed the estimated level in 2030. The current methods used for CO2 separation have serious operational and environmental constraints. To overcome these problems we have devised a supported ionic liquid membrane (SILM) incorporated with the blend of bimetallic metal-organic framework (MOF) of copper and magnesium ions (CuxMgx) and Trihexyltetradecylphosphonium chloride [P66614] [Cl] ionic liquid (IL). CuxMgx MOF were synthesized and characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD), and energy dispersive X-ray analysis (EDX). CuxMgx MOF with [P66614] [Cl] IL were immobilized on a flat sheet of polytetrafluoroethylene (PTFE) membrane. Single gas permeation tests of membranes loaded with 0.2/0.8 wt/wt% MOF/IL solution showed the highest CO2 permeability of 2937 Barrer and CO2/N2 selectivity of 33.26. The performance of SILM was also investigated with different water loadings of (30 wt % and 50 wt %) in addition to MOF/IL solution and at different feed pressure varying from 0.5 to 2 bars. Membranes showed enhancement in CO2 permeability to 3738 and 4628 Barrer whereas CO2/N2 selectivity decreased to 23.53 and 21.8 with membranes loaded with 30 and 50 wt % water, respectively, at a feed pressure of 2 bar. The gas permeation results show that the incorporation of CuxMgx MOF with IL in polymeric membrane enhances the CO2/N2 separation under humid conditions but slightly decreases CO2/N2 selectivity with an increase in feed pressure. The SILM synthesized in this research is highly viable for industrial flue gases because of the incorporation of phosphonium-based ILs that have high thermal stability. © 2022
ABSTRACT
The results of research conducted by Katadata in 2020 when the Covid-19 pandemic hit Indonesia showed that beauty products had the 2 highest sales after fashion. On the other hand, during the Covid-19 pandemic (social restrictions imposed), where not everyone was allowed to gather face-To-face, educational activities at school and college were conducted online. Everyone generally uses beauty products, however, during a pandemic, beauty product sales are still the 2nd highest. From this situation, this research was conducted with research questions, how do risk factors affect the Online Customer Experience Model specifically for beauty products during the covid-19 pandemic. This study uses 436 respondents who are customers of beauty products. This study uses quantitative methods with the Structural Equation Model and Partial Lease Square (SEM-PLS) techniques. It was found that the risk factors affecting the Affective Stage of 0.183 (18.3%), the risk factors affecting the Cognitive Stage of 0.127 (12.7%), the risk factors influencing the 0.225 (22.5%), the effect of risk factors on perceived control of 0.394 (39.4), the influence of factors risk of 0.089 (8.9%) on Repurchase Intention, the effect of risk factors on Trust in Online Shopping. The results of this research are very useful for industrial product development, especially the beauty industry. © 2022 ACM.
ABSTRACT
With the rapid development of China's new energy industry, the consumption demand for copper resources is increasing. As a key raw material, copper resources are becoming increasingly important. Taking the demand for copper commodities in China's new energy development as the research background and the international trade environment and pattern of copper supply as the research perspective, this paper makes an overall assessment of the commodity supply risk of China's copper industrial chain from 2010 to 2021 using the complex network and the newly established three-dimensional risk assessment model and finally reaches the following conclusions. The supply risk of commodities in China's copper industrial chain has been rising continuously since 2019 after experiencing fluctuating development in the early stage and a continuous decline in recent years, and there may be a trend of continuing to rise. The supply risk of China's copper industrial chain was gradually reduced from upstream to midstream and downstream, and the supply risk of copper smelting was more severe. The disruption potential risk of China's copper industrial chain was relatively low, and the international import market structure of copper commodities was relatively reasonable. The supply risk characteristics of each link in China's copper industrial chain were different. Due to the influence of import dependence, the copper mining industry had a high risk of trade exposure. However, the smelting and copper processing industries had certain limitations in production management, operation management and technology research and development, and their ability to withstand risks was weak. In addition, the impact of the domestic COVID-19 epidemic ha caused a high industrial chain vulnerability risk. © 2023 Elsevier Ltd
ABSTRACT
The coronavirus (COVID-19) pandemic has reemphasised the potential importance of having a unit or a formal structure that supports engineering students and faculty. Maintaining the integrity of teaching and learning during the pandemic necessitated collaboration, new skills, and new ways of thinking, for which many universities and faculties were unprepared. It is proposed that an Engineering Education Unit (EEU) would be able to facilitate new learning and thinking, an integrated view of collaboration and exploring new technologies. Therefore, this position paper provides a case for the establishment of an EEU and was aimed at answering the following research question: How can we position the integration of an Engineering Education Unit in South African universities which do not currently have such a formal structure? As a result, this paper aims to position how Engineering Education Research (EER) and engineering education practice can be integrated rather than separated. Furthermore, the scholarship of Engineering Education (EE) presents itself as an exciting space for collaborative thinking between engineering education scholars, engineering practitioners and engineering students. The researchers center their argument around three theoretically informed concepts in this position paper, namely (I) Community participation for skills development, (2) Crafting methodological relevance, (3) and Emerging economies such as the 4th Industrial Revolution (4thIR) / Industry 4. 0. Although several studies have examined clear distinctions between engineering education as practice-based and engineering education as research-focused, a strong focus on how an alignment of both fields could inform the agenda of an EEU has been lacking. As such, this position paper provides additional insights into the ways in which theory can inform the teaching and practice of engineering curriculum by establishing a Unit that is dedicated to the practical application of engineering education research. The Unit would be a place for engineering faculty to seek meaningful exploration in building community towards equitable, social participatory, engineering education learning experiences. The growing number of local and global institutions that have been engaging extensively with work in both the engineering education space and the education research space, support the justification for the establishment of such a Unit. It is envisaged that other universities can use the results of this position paper as motivation to establish their own EEU. Similarly, it can facilitate an understanding of the possible benefits of such a Unit. The anticipated benefits of such a Unit are: (i) furthering the engineering education research agenda, (ii) breaking down silos, (iii) interdisciplinary collaboration, and (iv) increasing student success. © 2022 IEEE.
ABSTRACT
Learning in times of pandemic represented a challenge for teachers and students, due to the difficulties generated by social distancing. During the Covid-19 pandemic, learning processes in educational institutions used multiple computer and electronic media. As for engineering programs, laboratory practices were discarded in many cases. This work develops a computer application with non-immersive virtual reality, applying a physical/actual laboratory guide in a virtual environment, in which a current loop for an Endress+Hausser PMD75 differential pressure transmitter had to be configured. This application was developed by students and the tutor of the AR/VR research incubator in conjunction with the teacher of the Industrial Instrumentation course, who acted as a client. The Unity3D game engine was used to simulate a tank, a cabinet and industrial instrumentation to measure the pressure at the bottom of the tank. Student were allowed to carry out the wiring of the different instruments inside the cabinet, and the configuration of the transmitter via a hand-terminal;In addition, the application includes a record of student events and interactions for future analysis. The perception of the application was evaluated through a survey applied to 43 students. The results showed that this tool, although it is a valuable support during virtual courses, and provides a first approach to real practice, the student requires interaction with real instruments. Therefore, the tool becomes a valuable complement prior to practices in a real laboratory. © 2022 IEEE.
ABSTRACT
As more and more companies adopt lean management as a system to continuously develop people, leaders are increasingly intent on conducting gemba walks. This means going to the workplace, be it production, engineering, or supply chain - to explore and discover important business challenges - often under the guidance of a sensei. As a result of the COVID-19 pandemic and the associated social distancing measures and travel restrictions, physical meetings in the workplace have been hampered, especially those involving outsiders. This has since led organizations to consider reducing travels and physical gatherings in general. Therefore, in this paper, we present assisted reality technology as a means of digitalizing gemba walks, allowing managers and executives to benefit from working with external sensei - albeit on a remote basis. We explore the use of RealWear HMT-1 technology as an enabler of the virtual sensei concept, comparing it with the more traditional face-to-face approach to gemba walks and offering insights from multiple interventions between external sensei offsite and local management representatives onsite. The assisted reality approach has been tested both within and across international borders. In general, we find that the digitalization of gemba walks using assisted reality offers multiple benefits over more traditional means. However, there are also several limitations. As such, this work has implications for both research and practice, in that we contribute towards the growing literature on digital lean manufacturing as well as offer practical guidelines for managers and executives embarking on a lean transformation. © 2022 IEEE.
