Diplomas are of particular importance in society, as they serve as official proof of education. Therefore, it is not surprising that counterfeits of such documents have become common. Thus, employers usually have to verify diplomas manually with the issuer. In line with the principles of social responsibility (accountability, transparence, ethical behavior, respect of stakeholders’ interest), ensure inclusive and equitable quality education (SDG 4) become a priority for universities. Blockchain technology creates opportunities to surmount these obstacles because it has revolutionized the way people interact with each other. For that purpose, a total of 147 students from a technical university in Romania answered questionnaires to determine how familiar they are with blockchain concepts and what they think about the implementation of this technology. Further, structured interviews were conducted with education and ICT experts to determine the main advantages and disadvantages, applications, and needs for adopting blockchain technology. Therefore, the objective of this paper is to explore the influence of blockchain on education through the assessment of 69 variables. The final part contains the consequences of the analysis’s findings and potential future advancements.

The automotive industry has set a highly demanding standard to meet customer satisfaction. The paper aimed to detail how quality analysis has been conducted to state the main causes that generated nonconformities of heat, ventilation and air conditioning (HVAC) systems. Problems have been reported on HVAC systems, such as noise, not being cold enough and moldy smell issues. All three problems determined by customer reports initiated the first contribution of this paper, namely by an initial quality study, and generated the investigation using is/is not problem scoping, data analysis, and graphical analysis. Pareto analysis and the Plan, Do, Check and Act (PDCA) approach are used to highlight the traceability of the actions performed in the evaluation of the problems and the detection of the causes related to each problem. The data analysis process and the data obtained from the analysis are the core of this paper. An immediate action plan is proposed, concluding with the hypothesis that the root cause is the blockage of the heater. This methodology has significant potential for being implemented, even for other components in the same industry or different sectors.

In this study, the production efficiency of a company’s manufacturing flow decreased, and therefore specific improvement actions on the tire manufacturing process were implemented. Additionally, the process improvement plan started with a deeper understanding of the activities, by using the SIPOC method (suppliers, inputs, process, outputs, customers). In order to identify the root-causes and the opportunities for improvement, quality instruments, such as the Ishikawa and Pareto quality tools, were used. The tire manufacturing process was reorganized using the 5S method, then the process was standardized and maintained through specific working procedures drafted on the standard operating procedure format. A particular device was designed for unlocking spring vents. Finally, the implementation of the redesign project shows added value as the entire manufacturing process improved by identifying weaknesses and correcting them. In addition to this, a different objective of the same company used in this case study is linked to adapting to market regulation requirements (the Economic Commission of Europe), with the aim to remain competitive. Therefore, well-defined processes and a strategy based on continuous improvement are needed. The methodology may be transferred to other industries.
