Preventive Maintenance as a Critical Success Factor in Industry 4.0

In an economy that tends to operate in real time, where companies reduce stocks and value the customization of products and services according to the needs of their customers, information systems and technologies assume a predominant role. Equipment maintenance proves to be critical in supplying markets and meeting consumer needs. Regarding the maintenance of equipment, most managers are faced with the technical indications of suppliers, serving as a reference for the respective interventions. However, these indications often do not contemplate the contingency of certain situations, excessive hours of operation, or temperatures higher than those indicated. Preventive maintenance assumes an important role in the maintenance area by allowing interventions that are more appropriate to the wear and tear of the equipment. The technological potential associated with the internet of things or analytics allows the generation of economic value by guaranteeing the adequate conditions of the equipment and by avoiding disruptions in supply to the markets.

A Novel Ripple and Cyber Bullies Data Disclose (RACYBDD) Framework to Protect Images on Social Media

Due to the advancement in internet technology, everyone can connect to anyone living anywhere in this world who is far away from us by using social media. Social media became a public place to share everyone's personal photos and videos. These photos or videos are viewed, shared, and even downloaded by their respective friends, someone from their friends' profiles, and even unrelated persons also without their permission. One of the risks from the social media is the cyber bullying or online harassment. Cyber bullies perpetrate either through denigration or doxing. The cyber bullies are anonymous, and it is very difficult for us to catch and punish them. The main aim of this chapter is to provide the privacy and security to the photos that are sharing on social media. This chapter proposes a novel algorithm to keep the photos safe that are uploading on social media and the extension of the novel algorithm to reveal the details of the cyber bullies those who performed morphing on the photos that were downloaded from social media.

Data Governance in the Digital Age

In the contemporary organizational context, the sharing and transfer of knowledge play a significant role, and therefore, it is important to overcome internal and external barriers for them to be processed. This can be facilitated by the implementation of data governance (GovD). The problem is that, in addition to being a new construct and still little studied, conceptual divergences are fed by the amplitude the possible dimensions of analysis. In this context, the objective of this study arises in identifying the conceptualization of the construct governance and data proposed in the scientific literature to support its better understanding and perspective of future investigations. A theoretical research was conducted through a systematic literature review, followed by an analysis of the most relevant publications on the subject. The discussions about this subject are considered in the context of contemporary organizations; however, it signals the importance of future studies of empirical and theoretical order to foster discussions on the subject today.
