Introduction
In the second decade of the twenty-first century, the world stands on the cusp of industry 4.0 paradigm which has remarkably become global emergence with a core of industrial transformation, revitalization, and development [1]. Simply put, industry 4.0 is the integration of cyber and physical worlds through introduction of new technologies in the industrial fields [2,3]. In other words, it is a technological revolution in every production system including operator and maintenance [4], which is quite unique from the previous revolutions as shown in Table 1 [5][6][7][8][9]. Industry 4.0 is the digitization of the industrial value chain which has become unexampled for economic and social development in the recent years [10][11][12]. On the one hand, it allows highwage countries to maintain their business responsiveness and competitiveness [13]. On the other hand, research and development units are organizationally, personally, and methodically being aligned for innovation competitiveness [14,15]. Industry 4.0 is a data-driven production system which is progressing exponentially while reshaping the way individuals live and work essentially. erefore, the public remains optimistic regarding the opportunities it may offer for sustainability and the future of quality work in the global digital economy [16][17][18][19][20]. Actually, industry 4.0 is increasingly being promoted as the key for improving productivity, promoting economic growth, and ensuring the sustainability of manufacturing companies [21][22][23]. Moreover, it aims to improve the flexibility, adaptability, and resilience of the industrial systems [24,25]. Industry 4.0 has been considered a new industrial stage in which several emerging or disruptive technologies including Internet of ings (IoT), artificial intelligence (AI), 3D printing, and big data are converging to provide digital solutions [26,27]. Industry 4.0 is characterized by the mass employment of smart objects in highly reconfigurable and thoroughly connected industrial product-service systems [28]. In this respect, industry 4.0 phenomenon is bringing unprecedented disruptions for all traditional production/ service systems and business models (value chains) and hotfooting the need for redesign and digitization of activities [29][30][31][32]. Tout ensemble is retrofitting and/or redefining the patterns of value creation and annexations, production networks, and supplier base and customer interfaces [33][34][35]. e concept of industry 4.0 is greatly linked to other concepts such as servitization [36,37], crowdsourcing [38], circular economy (sharing economy) [39][40][41][42][43][44], green economy, and bioeconomy [45]. Besides being complemental to a vast number of existing concepts, the main strength of industry 4.0 is the promises for shorter delivery time, more efficient and automated processes, higher quality, agility in production, and profitable and customized products [46,47]. Furthermore, it is expected to create extra values as the world is massively experiencing digital transformation [48]. In this regard, industry 4.0 has not only opened windows of opportunity for emerging economies but also brought its own bureaucracy in terms of the main challenges that these changes pose to firms, industrial systems, and policy approaches [49]. e curiosity and the need to contemplate the meaning and concept of industry 4.0 have been ubiquitous among academic and business communities and thus make industry 4.0 to be one of the most important topics in the modern world as a result of digital milestones in the innovation area [50]. So far so good, there are several ambiguities with almost 100 definitions and related concepts of industry 4.0 already in existence among academic and nonacademic literature [51]. In the academic community, engineering has incredibly gained more attention to the industry 4.0 topic than other subject areas including computer science, chemistry, and energy ( Figure 1) [52]. e rapid and fascinating adoption of the industry 4.0 topic among academic and business entities has led to the massive use of icon or neologism "4.0" to depict industry 4.0 disruption in the systems, processes, activities, or even industrial sectors. However, the collective numbers and names of the existing industry 4.0 neologisms have remained unclear [53]. In addition, industry 4.0 disruption through the convergence of its technologies has been ill-defined among previous researchers [26]. To this end, the outstanding contributions of the present study are trifold: (1) identify industry 4.0 neologisms used among the academic and business communities, (2) clearly understand industry 4.0 disruption in education industry (education 4.0), energy industry (energy 4.0), agriculture industry (agriculture 4.0), healthcare industry (healthcare 4.0), and logistics industry 3. Industry 4.0 Neologisms e concept of industry 4.0 originated from the manufacturing industry purposely to improve the engineering excellence from machine building to informatization [55]. However, nowadays, the concept of industry 4.0 has expanded enormously, and its definition spans beyond engineering, smart and connected machines, and systems and has become a more general concept with mainstream appeal and applicability [56]. is can be evidenced by a multitude of neologisms such as fashion 4.0 and care 4.0. Interestingly, the icon "4.0" and beyond (e.g., "5.0") have spread exceedingly as witnessed by the fact that the combination of a noun and the icon "4.0" is used to signal and usher in discussions about the future of business and society [53]. In this study, 99 industry 4.0 neologisms were identified and categorized into 6 areas based on the subject of the published literature as depicted in Table 2. However, the previous study done by Madsen [53] reported only 37 neologisms. is alone can divulge that there is an increasing  e disruptive landscape of industry 4.0 is so strong that change is inevitable, including within the education industry [176], making education 4.0 the illustrious cant among educationists today [177,178]. Education 4.0 is an advanced education and networked ecosystem capable of developing skills and building competences for the new era of manufacturing [106]. In other words, education 4.0 is advanced engineering education for industry 4.0 [179,180]. Furthermore, it is termed as higher education in the fourth industrial revolution [181][182][183][184]. Moreover, education 4.0 can be defined in terms of OECD future education and skills 2030 [185] and PhD program in the era of industry 4.0 [186]. Simply put, education 4.0 is creativity-focused technology education in the age of industry 4.0 [187].

Major Industrial Sectors
Generally, education 4.0 came forth in response to industry 4.0 which is a technology-and data-fueled world [188]. It has similar remarkable trends of (r)evolution just as industry 4.0. Table 3 shows the characteristics of each education evolution [189][190][191][192][193][194][195]. Education 4.0 is the most complex system as compared to the previous evolutions.
is is derived from the fact that industry 4.0 disruption is introducing rapid and unbelievable changes and challenges including the issue of skills and job profiles [196]. erefore, it poses the question of how to educate and prepare new logical innovations and to develop not only left-brain skills but also right-brain skills [197]. As a result, education 4.0 topic has attracted a number of researchers in the recent year. Lately, the World Economic Forum developed education 4.0 framework that can be easily adopted and implemented by any institution, government, or university as presented in Table 4 [198].

Learning Factory.
As far as education 4.0 is concerned, adequate and innovative manufacturing education and training are required in order to prepare employees for changes in their working environment related to quickly advancing digitalization. Most importantly, theoretical knowledge and practical skills regarding data acquisition, processing, visualization, and interpretation are needed to exploit the full potential of digitalization [199]. Consequently, the concepts of learning factory (LF)/teaching factory and innovation laboratory have egressed in the recent epoch as the lucrative approaches for qualification of participants from the field of engineering, especially industrial and mechanical engineering [200][201][202][203][204].
LFs offer a suitable environment to combine theoretical learning and practical application and are therefore predestined to impart industry 4.0 knowledge and skills [205]. LFs are employed to teach students how the methods and Publications included in this study = 797 Figure 2: e flowchart diagram for the literature search strategy used in this study. N � n 1 + n 2 + n 3 + n 4 + n 5 represents the total number of PDF files downloaded from the respective databases. Journal of Engineering 5 concepts are learned in theory work in a hands-on and industry-related environment [200]. Elaborately, LFs are a platform created to provide an effective learning environment that will bring about human capacity development in a bid to bridge the gap between learning and practice (i.e., the gap between academia and industry) [206,207]. e promising strength of LFs is the ability to solve problems in a structured way which is an essential competence of people in   Personalized and selfpaced learning Move from a system where learning is standardized to the one based on the diverse individual needs of each learner and flexible enough to enable each learner to progress at their own pace Accessible and inclusive learning Move from a system where learning is confined to those with access to school buildings to the one in which everyone has access to learning and is therefore inclusive Problem-based and collaborative learning Move from process-based to project-and problem-based content delivery, requiring peer collaboration and more closely mirroring the future of work Lifelong and studentdriven learning Move from a system where learning and skilling decrease over one's lifespan to the one where everyone continuously improves on existing skills and acquires new ones based on their individual needs a factory, from the shop floor operator to the management level factory [208]. Furthermore, LFs are an effective solution to deal with new technologies, concepts, and methods [209]. Generally, LFs develop a uniform, unambiguous concept of competence that can be applied to production technology in the engineering community [210]. However, the requirements for the planning, implementation, and operation of an academic LF vary depending on the specific area of the respective institution [211]. For instance, the use of LFs differs for education in maintenance, manufacturing, production design, and technology adoption [212]. To this end, several learning factory concepts have been developed including game-based learning or gamification for manufacturing education [213] and Internet of ings laboratory (IoT lab) [214]. Table 5 outlines some examples of the learning factories launched majorly by institutions. higher level of operational efficiency, productivity, and automatization, it brought bureaucracy as huge amount of energy and materials is demanded and extremely large amount of solid, liquid, and gaseous wastes or greenhouse gases is generated from these complex industrial systems [237,238]. erefore, smart factories need to be sustainable and renewable in terms of energy pattern (electric system industry) [124,[239][240][241]. Furthermore, the United Nations Industrial Development Organization (UNIDO) has set the relevancy of industry 4.0 and sustainability in the global Sustainable Development Goals (SDG 7 and 9) that digital industrial development should support the growth of industrial sustainable energy [242]. is has pointed towards the evolution of new energy concept known as energy 4.0. Energy 4.0 is a digital revolution in the energy sector and also known as smart energy or green energy [99]. It presents opportunities for companies to establish new business models and sustainable strategies of producing and delivering energy [99]. Moreover, the idea of energy 4.0 is based on accelerating clean energy through adoption of the industry 4.0 concept in the energy sector [243]. e energy transition from 1.0 to 4.0 can be traced back in a similar manner to that of the web system as illustrated in Figure 3

e Drivers of Energy 4.0.
e concept of energy 4.0 is nascent, and therefore, no clear information on its concept exists so far in the literature [99]. Nevertheless, renewable energy is fundamental to the energy 4.0 epoch. However, the transition to intermittent energy production from renewable energy sources increases the complexity of providing reliable energy supply. is has been handled with the introduction of digital or smart energy systems [244]. e truth is that smart renewable energy ware systems lie at the core of industry 4.0, and a number of recent advanced technologies and approaches play pivotal roles by exploiting innovative technologies and optimization methods [241]. For instance, the production of crude biofuels obtained from biomass and renewable energy sources is unheard-of. e biomass crude oil generation technology is currently up-to-date in terms of reducing dangerous emissions into the environment [245]. In addition, offshore and onshore wind energy harvesting has become the driving force towards the realization of energy 4.0 in most developed and developing countries [100].
Another key driver of energy 4.0 is how to reduce energy consumption whilst maintaining or increasing profits and productivity. e fact that energy requirements have grown due to automation of industrial systems makes energy optimization central in energy 4.0.
us, a number of sophisticated energy-efficient mechanisms and software have been developed including real-time embedded systems [246] and computational modeling (e.g., energy efficiency analysis modeling system) [247][248][249].
Additionally, the advancement in power distribution is another driver of energy 4.0. is is accomplished through the integration of conventional power grid system with industry 4.0 technologies including IoT, big data, and AI. e combination of these technologies and power grid has been cited as smart grid [99].
Furthermore, the advancement in the energy storage system which employed nanotechnology as one of the core technologies for its development is emblematic to energy 4.0. Currently, the next-generation lithium-ion batteries are under rapid development using various nanostructured materials including silicon nanowires and silicon nanotubes which are two promising anode materials due to their high specific capacities [250]. e disruptive waves of industry 4.0 in agriculture and food systems (agri-food) can be witnessed from the digital transformation of the production infrastructures such as connected farms, new farm equipment, and connected tractors and machines [251,252]. e driving force behind this is the need to increase efficiency, productivity, and quality in agri-food systems and environmental protection (reduce global warming) [253,254], that is, the sustainability of agricultural systems which is paramount important for the survival and wellbeing of humans worldwide [255]. In fact, agriculture plays a great role in providing human food security and sustainability in any country [256]. erefore, to meet this ever-increasing food demand in the epoch of industry 4.0, the new concept "agriculture 4.0" was born [82]. Agriculture 4.0 is known with several names including data-driven and automated agriculture [172,257], intelligence agriculture [258], smart agriculture [259], digital agriculture [260], digital farming [261], smart farming [262], and farming 4.0 [83]. Agriculture 4.0 emerged when telematics and data management were combined to the already known concept of precision agriculture (improving the accuracy of operations) [172]. Agriculture 4.0 can further be defined as farming in the era of industry 4.0 through digitalization [263]. Moreover, it is the future of farming technology which is based on the emergence of smart technology including smart devices (sensors and actuators) and communication technology [263,264]. Simply put, agriculture 4.0 is the fourth evolution in the farming technology which is unparalleled to the previous (r)evolutions ( Figure 4) [168,172,265]. Some authors have argued that it should be called "agriculture 5.0" [171], but it is not yet common among the academic and nonacademic literature.
Similar to industry 4.0, agriculture 4.0 is universally complemental to a number of concepts including vertical farming and food systems, bioeconomy, circular agriculture, and aquaponics [266]. Agriculture 4.0 is composed of existing or developing technologies such as robotics, nanotechnology, synthetic protein, cellular agriculture, gene editing technology, AI, blockchain, and cloud computing [266].
Importantly, food and farming systems must reconcile the need to produce enough healthy and affordable food with the equally important motive of ensuring that humans do not degrade the ecosystems on which they entirely depend for sustenance [171]. On the one hand, agriculture industry is critical to sustainable development, and agricultural production by smallholders in lower-income It focuses on planning, operation, and analysis of flexible manufacturing systems (FMS). e aim is to allow the students to achieve the intended learning outcomes mostly with learning by doing. [226] 8 Automated class room is is an industrial cyber-physical system (ICPS) demonstration platform. It is used as a practical testbed, where students from different departments can learn together on how to implement the industry 4.0 concept and technologies. [227] 9 Industrie 4.0 learning factory It aims to support "made in China 2025" strategy with necessary qualification of employees in Chinese production companies. [228] 10 Training Factory Stator Production It aims at providing small-and medium-sized companies, particularly those affected by change, with the opportunity to train their employees. [229] 11 MTA SZAKI learning factory It aims at providing infrastructure, learning content, and opportunities for future production engineers, with a strong emphasis on automation and human-robot collaboration. [230] 12 Chair of production system (LPS) It aims at teaching industry 4.0 requirements in application and development. [231,232] 13 LogCentre learning factory It aims at availing a low-cost environment for German Kazakh University in Almaty, Kazakhstan, to learn how state-of-the-art concepts and technologies are applied in logistics systems, e.g., RFID. [233] 14 Learning Factory advanced Industrial Engineering (LF aIE) LF aIE is a model factory at the Institute of Industrial Manufacturing and Management (IFF) of University of Stuttgart designed for training on methods of production optimization. [201,234] 15 AAU Smart Production Lab is is the Aalborg University (AAU) learning factory. It has implemented industry 4.0 nine core technologies including collaborative robots, virtual environments, horizontal and vertical system integration, industrial Internet of ings, cyber security, use of cloud service, additive manufacturing, and big data and analytics for training purposes. [235] 16 TU Wien Pilot Factory Industry 4.0 (TUPF) countries contributes substantially to the food security of both rural and urban populations [267]. On the other hand, food industry is a key issue in the economic structure due to both weight and position of this industry in the economy and its advantages and potential [268]. In order to harness and control both agriculture and food industries, a complex industry (agri-food) has emerged, better known as "agrifood 4.0," in the era of the fourth industrial revolution [96,98,269]. In fact, the term agri-food 4.0 is an analogy to the term industry 4.0, coming from the concept of agriculture 4.0 [95]. In this regard, agriculture 4.0 was adopted in this study to cover all the aspects of food and agricultural industries.

Convergence of Disruptive Technologies in Food and
Agriculture. More like in the manufacturing system, industry 4.0 is disrupting agricultural and food systems through the convergence of its technologies [26]. In order to understand and illustrate this fact, a massive exploratory     [27], and these included 3D printing (3DP), AI, augmented reality (AR), big data, blockchain (BC), cloud computing (cloud), drones, IoT, nanotechnology (nanotech), robotics (robots), simulation (Sim), and synthetic biology (Syn-Bio). e identified applications were categorized into 10 major application areas in agriculture and food systems, namely, food processing and management (FPM), farm equipment and facility maintenance (FEFM), agriculture machinery automation (AMA), general agri-food planning and operation management (GAFPOM), yield prediction and precision farming (YPPF), weather and environment management (WEM), land preparation and planting optimization (LPPO), crop and livestock growth, improvement and protection (CLGIP), food packaging and storage (FPS), and irrigation and water management (IWM) as shown in Table 6. ese application areas were derived just from the mentioned applications in the collected relevant publications. So, by mapping the application areas with the disruptive technologies, the convergence of these technologies is clearly visible as illustrated in Figure 5. e quantitative analysis involved counting the converging technologies in each application area and calculating the percentage convergence as shown in Table 7. e result demonstrates that the application areas GAFPOM and YPPF were the dominant with 17% technology convergence followed by WEM and CLGIP with 15% and then LPPO (11%) ( Figure 6). However, each application area has totally different sets of technologies in convergence. For instance, the technologies converging in the GAFPOM application area include AI, AR, big data, blockchain, cloud computing, drones, IoT, robotics, and simulation, whilst the technologies converging in YPPF include AI, AR, big data, cloud computing, drones, IoT, nanotechnology, robotics, and synthetic biology. ese differences were also observed in the other application areas. e disruptive and transformative waves of industry 4.0 which are incredibly retrofitting many industries have also paved its way into the healthcare industry or medical fields including orthopaedics and dentistry. As the result of the tremendous disruption into the healthcare system, a new concept termed as "healthcare 4.0" has evolved [398][399][400][401]. Although the implementation of the healthcare 4.0 concept has been characterized as being highly complex and costly and requires a more skilled labor force, a number of hospitals in the advanced countries are already embracing it [402,403]. e driving force behind this healthcare (r)evolution is the need to deploy industry 4.0 technologies to deliver more effective and efficient healthcare services including high security and privacy on the patients' data electronic health record while allowing remote and real-time access and diagnosis by the doctors or healthcare personnel [404][405][406][407].
Healthcare 4.0 is also known as hospital 4.0 [123]. It is a term that has egressed recently and derived from industry 4.0. Simply put, healthcare 4.0 is digital health or the use of digital technologies for health. e term digital health is rooted in electronic health (eHealth). eHealth is defined as the use of ICT in support of health and health-related fields, while mobile health (mHealth), which is a subset of eHealth, entails the use of mobile wireless technologies for health. On the contrary, healthcare 4.0 germinated as a broad umbrella term encompassing eHealth (which includes mHealth), as well as emerging areas, such as the use of industry 4.0 technologies including IoT, big data, 5G, AI, computing (cloud, fog, and edge), and blockchain [408][409][410][411][412][413][414]. Holistically, the World Health Organization (WHO) [408] reiterated the term healthcare 4.0 as a discrete functionality of digital technology that is applied to achieve health objectives and is implemented within digital health applications and ICT systems, including communication channels such as text messages. In a similar manner to industry 4.0, the healthcare industry has revolutionized from 1.0 to 4.0 as illustrated in Figure 7 [415][416][417]. Besides the implementation of industry 4.0 technologies in the healthcare system, there are ongoing studies in the development of healthcare services including the Social Cooperation for Integrated Assisted Living (SOCIAL) [418], OpenEHR [419], GraphQL, and HL7 FHIR [420]. is is because healthcare service and management plays an essential role in the human society [421,422]. ese are also contributing a lot to shaping the journey of healthcare 4.0.
One of the factors that is boosting the adoption of healthcare 4.0 is the concept of smart city. Smart healthcare is an essential part of creating a smart city because anyone can go to the hospital for treatment [423]. To this far, some of the major players in healthcare 4.0 include Abbott Laboratories, Philips Healthcare, Life Watch, GE Healthcare, Omron Healthcare, Siemens Healthcare, and Honeywell International Inc. [424]. Nevertheless, the healthcare industry lags behind other industries in protecting its data from cyber attacks [425]. e strength and the benefit of healthcare 4.0 adoption have been witnessed in the fight of the novel coronavirus 2019 (COVID-19) pandemic [426]. Coronavirus is one of the viral respiratory illnesses and can be fatal to some immunocompromised patients [427]. However, combating this pandemic has become a global hurdle. As a lifesaving strategy, a number of healthcare facilities have devoted to using 3D-printed patient respiratory ventilators and breathing equipment to sustain the life of patients [428].

Journal of Engineering
For the case of supply chain management, industry 4.0 with its associated technological advances is increasing supply chain resilience or lean supply chain management which is highly linked to the general operation and performance of the logistics industry [538][539][540].
Globalization, finance, governance, leadership, and society at large play an astonishing role in enhancement of the general performance and development of the logistics industry as well as economic growth in any country [569][570][571][572][573]. Most importantly, delivering on digitalization for large multinational business, in the contemporary context of global operations and real-time delivery, is a significant opportunity to the logistic industry [574,575]. In globalization, all the three modes including trade, financial, and technological globalizations are now practiced everywhere in the world as an important and economic reason for    company improvement [576][577][578]. However, globalization in the era of industry 4.0 has taken a quantum leap into a new concept known as "globalization 4.0" which is among the main drivers of logistic 4.0 [579]. One of the key countries behind globalization 4.0 is China. China's Belt and Road Initiative is an important vector for globalization 4.0 as it helps to bring its enabling infrastructure and technologies to all corners of the globe [580]. Table 11 depicts the transition or (r) evolution from 1.0 to 4.0 for globalization, leadership, and society [581][582][583][584][585].
Similarly, finance sectors in the logistic industry are leapfrogging as disruptive technologies paved their ways into services and financial inclusion. In most organizations today, finance professionals are being asked to learn new skills, often related to such technologies, because work is morphing into more project-oriented opportunities. For instance, the major challenges that chief finance officers of the logistics industry are facing include handling massively big data, liquidity and cash flow, complicated cash lifecycle finding, and retaining good talent [586]. In order to overcome these hurdles in finance systems for the logistics industry, a new concept of finance called "finance 4.0" was born, which is driven by digital transformation in the finance and banking system [587][588][589]. Figure 10 elaborates three generations of finance and banking systems from 2.0 to 4.0 [145,[586][587][588]590].

Conclusions
Just like the light set-up in the morning, the disruptive landscape of industry 4.0 in the industrial sectors is unlimited. is can be evidenced from the explosive use of neologism "4.0" among the academic and business communities. e convergence of disruptive technologies is incredible, and this is the remarkable power of industry 4.0 disruption in any industrial sector. Adoption of education 4.0 through implementation of the learning factory is paramount important for building the requisite skills into the workforce for industry 4.0. e concept of energy 4.0 is still nascent, and thus, much research is required to ensure its success because the amount of energy requirement has reached unprecedented level due to the automation of the industrial plants to make them industry 4.0-compliant. e present study demonstrated the convergence of disruptive technologies in agriculture, healthcare, and logistics industries. is might not depict the real-life situation because the study was solely based on the published literature and therefore limited by the availability of information. Nonetheless, it provides an insight into the convergence of industry 4.0 technologies in the industrial sectors. A number of disruptive technologies, however, have received very few applications in these selected industries. is points out the need for more research to increase the application areas of these technologies. More especially, application of synthetic biology in logistics needs to be investigated. Additionally, application of disruptive technologies in the field of dentistry should be expanded. e convergence of disruptive technologies in education and energy sectors should also be investigated.
