Required Quality

Today’s market drives companies to change, adapt, and compete. Many consumers are increasingly looking at price, without sacrificing quality. In order to be attractive to the customer, companies must be able to offer the required quality at the lowest possible price. The life cycle of many products has been shortened compared to the past because now technologies are evolving faster. For these reasons, it is important that companies reevaluate all the operations that are carried out within them, to optimize them and eventually adopt new technologies if they offer interesting opportunities. In this discussion, we first study the design for disassembly, a technique that can bring several advantages during the life cycle of a component, offering the possibility of reducing time and cost of disassembling a product, and better reuse of the different materials of which it is composed. Subsequently, augmented reality is discussed, and how this technology is exploited in the world, especially in the industrial sector. During the work, we discuss a case study, with the gearbox being the object of analysis. This allows us to apply the theoretical concepts illustrated in a concrete way, allowing for a better understanding of the topics.

Disassembly Sequence

Environmental impact and recycling have been increasingly frequent topics in recent years. At the same time, the life cycle of products has increasingly become shorter, as the escalating competitive market requires new products in smaller pieces. From this perspective, the recovery of parts and products that are produced in this market system for subsequent reuse when they reach the end of their life cycle is essential. For these reasons, it has become critical that companies re-evaluate their product design with a view to the possible recovery of the parts that comprise their products and to create new products for the market. The following discussion was based on the study of design for disassembly (DfD), which is the analysis of industrial products aimed at optimizing disassembly in terms of time and costs. The application of the DfD to a case study of a gearbox has, among its main objectives, the search for the best disassembly sequence in terms of time and money. During the course of the study, augmented reality (AR) was used. Through the use of the Unity software and Vuforia package, it was possible to bring the gearbox back to AR and then simulate the disassembly sequence in AR.

The Impact

Transformation of digitalization in large industries has an impact on the automation of production equipment, including the replacement of production machines from conventional machines (manual) to digital machines. Meanwhile, automation of production equipment requires workers with higher skills, in fact the existing workforce does not have expertise in carrying out all-digital equipment. The impact is a reduction in labor (layoffs). Machine replacement is done in stages so that the reduction of workforce (PHK) in bulk is not visible. However, the inconsistency between the preparation in the world of education and the needs in the world of work continues to occur today. Until now, vocational development based on local resources has not been operating optimally and needs serious attention from the local government. The government on various occasions mentioned four leading sectors that will be strengthened in the development of vocational institutions, namely maritime, tourism, agriculture (food security), and the creative industry. In addition, the government is also developing a policy scheme for Skill Development Funds (SDF), which is a skills improvement program for workers affected by automation (PHK), including through Vocational Training Center (BLK).

The World

With the rapid development of applications for mobile platforms, developers from around the world already understand the need to impress with new technologies and the creation of such applications, with which the consumer will plunge into the world of virtual or augmented reality. Some of the world’s most popular mobile operating systems, Android and iOS, already have some well-known tools to make it easier to work with the machine learning industry and augmented reality technology. However, it cannot be said that their use has already reached its peak, as these technologies are at the stage of active study and development. Every year the demand for mobile application developers increases, and therefore more questions arise as to how and from which side it is better to approach immersion in augmented reality and machine learning. From a tourist point of view, there are already many applications that, with the help of these technologies, will provide more information simply by pointing the camera at a specific object.Augmented Reality (AR) is a technology that allows you to see the real environment right in front of us with a digital complement superimposed on it. Thanks to Ivan Sutherland’s first display, created in 1968 under the name «Sword of Damocles», paved the way for the development of AR, which is still used today.Augmented reality can be divided into two forms: based on location and based on vision. Location-based reality provides a digital picture to the user when moving through a physical area thanks to a GPS-enabled device. With a story or information, you can learn more details about a particular location. If you use AR based on vision, certain user actions will only be performed when the camera is aimed at the target object.Thanks to advances in technology that are happening every day, easy access to smart devices can be seen as the main engine of AR technology. As the smartphone market continues to grow, consumers have the opportunity to use their devices to interact with all types of digital information. The experience of using a smartphone to combine the real and digital world is becoming more common. The success of AR applications in the last decade has been due to the proliferation and use of smartphones that have the capabilities needed to work with the application itself. If companies want to remain competitive in their field, it is advisable to consider work that will be related to AR.However, analyzing the market, one can see that there are no such applications for future entrants to higher education institutions. This means that anyone can bring a camera to the university building and learn important information. The UniApp application based on the existing Swift and Watson Studio technologies was developed to simplify obtaining information on higher education institutions.

Digital technology is at the forefront of transforming how governments operate around the world. Using Brunei's Information Department (InfoDept) as a case study, this chapter looks at how the agency has evolved from its inception in the 1950s to 2019 in its embrace of both old and new media to pursue its mission and objectives as a government-run media agency. The results demonstrate how new media, such as social media, can complement old media if done right. The case study on InfoDept contributes to the growing field of research related to the increased advancement, development, application, and impact of new technologies in bolstering the digital governance process. This chapter also provides strong evidence on how governments can improve its general governance process and unlock the digital dividend in the 21st century by incorporating new media into its public policy architectonic. Salient lessons for policymakers and practitioners on digital governance have also been presented in this chapter.

As China's coffers have swelled over the past three decades, its citizens' waistlines have also expanded. Western goods and lifestyles habits are consistently being imported into the Asian giant, including the obesity epidemic. Chinese children are particularly susceptible and future generations face tremendous health risks despite medical advances. States and international bodies such as the World Health Organization are alarmed at the damage obesity is already producing. The price tag to treat the health problems associated with obesity and the rsulting loss in economic productivity is staggering. While this essay uses China as a case study to examine the causes of obesity and its consequences, social and economic health, the grim reality is that this pattern is occurring worldwide as countries develop and their people adopt Western "nutritional" norms.

The Relationship

With the advent of new technologies, the man begins to experience a significant change in the perception of the other, time and space. The acceleration of time promoted by new technology does not allow the exercise of affection for the consolidation of ties, relations take narcissists hues seeking immediate gratification and the other is understood as a continuation of the self, the pursuit of pleasure. It is the acceleration of time, again, which leads man to present the need for immediate, always looking for the new – not new – in an attempt to fill an inner space that is emptied. The retention of concepts and pre-stressing of temporality are liquefied, become fleeting. We learn to live in the world and the relationship with the other in a frivolous and superficial way. The psychic structure, facing new phenomena experienced, loses temporalize capacity and expand its spatiality, it becomes pathological. Post-modern inability to retain the past, to analyze the information received and reflect, is one of the responsible for the mental illness of today's society. From a temporality range of proper functioning, the relationship processes with you and your peers will have the necessary support to become viable and healthy.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Metaheuristic Methods

The work carried out has the purpose of improving and optimizing various industrial technical operations, such as preventive maintenance, taken here as an example of application, using the Design for Disassembly (DfD) technique. Therefore, through four metaheuristic methods that have been chosen among the most widespread in the field (described below) to make a comparison between them, the optimal disassembly sequence is sought, if it exists, in terms of time and then costs in order to extract a target component without damaging the other mechanical parts of the assembly. The hypothesis that has been tested throughout this case study is “a responsible application of DfD, not only from the design process of a product but also during the disassembly procedure, can bring substantial benefits to the company”. Interaction with a hypothetical operator in charge of the work to be performed is implemented with the use of augmented reality. In fact, through an application programmed for an Android device (in this case, a mobile phone, hence a handheld device), the operator can be instructed step-by-step on the disassembly sequence in dynamics as an animation. Finally, two virtual buttons were added in augmented reality with which the operator can start and pause/resume the animation at any time to facilitate the understanding of the different steps established by the sequence.

This book is an in-depth case study of the Furness Withy and Co Shipping Group, which operated both tramp and liner services and was one of the five major British shipping groups of the early twentieth century. It demonstrates how British shipowners of this period generated success by exploring Christopher Furness’ career in relation to the social, political, and cultural currents during a time of tremendous shipping growth in Britain and the establishment of some of the largest shipping firms in the world. It approaches the study from three angles. The first analyses how the Furness Group expanded its shipping activities and became involved with the industrial sector. The second illustrates the organisational and financial structure of the enterprise. Finally, the Group’s leadership and entrepreneurship is scrutinised and placed within the wider context of twentieth century British business. The case study begins in 1870, with an introduction explaining how Christopher Furness came to join the family company, Thomas Furness and Co. in order develop services, expand, and instigate the changes and mergers that brought the Furness Group into existence. There are thirteen chronologically presented chapters, a bibliography, and seven appendices of data including an ownership timeline, tonnage statistics, acquisitions, a list of maritime associates, and a timeline of Christopher Furness’ life. The book concludes in 1919 with the de-merging of the Furness Group’s shipping and industrial holdings, the resignation of the Furness family from the company’s board, the sale of their shares, and the move into managing the firm’s industrial interests.

Abstract Consumer behavior is shifting radically with the rise of e-commerce and new technologies. As a result, luxury retailers are forced to embrace a variety of technologies to keep their customers engaged. How do brands captivate shoppers and provide the customer experience that will satisfy their desires? Through dissemination of literature and case studies on examples from the industry, this paper presents a detailed discussion on the new approaches to customer experience in the luxury fashion industry, in the context of a modern economy that is highly shaped by disruptive technological innovations. The discussion includes two detailed case studies, focusing on two key themes that define contemporary customer expectations: the story – discussing customer’s desire to be immersed in the narratives behind catwalk collections, and the experience – discussing the use of technology to create a unique retail space through the use of online and mobile specific technologies. The first case study focuses on how new technologies provide brands with new opportunities to present their products through narratives. Using famous luxury retailers Dior, Givenchy and Prada as examples, the case study provides a detailed discussion on the use of virtual reality and augmented reality as tools that enable customers to project themselves into the story behind a catwalk show and become active characters in the narrative, through the use of technological devices. The second case study focuses on the importance of merging the online and the traditional brick-and-mortar store. “The Store of the Future”, by luxury retailer Farfetch is used as an example of how retailers make use of high-tech equipment, virtual reality and augmented reality not only to create a tech-powered interactive experience that will intrigue customers, but also to improve retail productivity by capturing customer data. The study adopts a qualitative research method to evaluate the validity of the concepts discussed in the Literature Review, using a sample of three in-depth interviews with industry experts, focusing on the use of technology to improve customer experience in physical retail spaces. Based on previously published research, it is estimated that the primary research will indicate that it is not the use of technology that drives the customer experience, but customer expectations that determine the adoption and adaptation of disruptive technologies to satisfy the shoppers’ requirements.

In the past two decades, pandemics of several fatal coronaviruses have posed enormous challenges for public health, including SARS-CoV (2003), MERS-CoV (2012), and SARS-CoV-2 (2019). Among these, SARS-CoV-2 continues to ravage the world today and has lead to millions of deaths and incalculable economic damage. Till now, there is no clinically proven antiviral drug available for SARS-CoV-2. However, the bioactive molecules of natural origin, especially medicinal plants, have been proven to be potential resources in the treatment of SARS-CoV-2, acting at different stages of the viral life cycle and targeting different viral or host proteins, such as PLpro, 3CLpro, RdRp, helicase, spike, ACE2, and TMPRSS2. They provide a viable strategy to develop therapeutic agents. This review presents fundamental biological information on SARS-CoV-2, including the viral biological characteristics and invasion mechanisms. It also summarizes the reported natural bioactive molecules with anti-coronavirus properties, arranged by their different targets in the life cycle of viral infection of human cells, and discusses the prospects of these bioactive molecules for the treatment of COVID-19.
