E-learning is an evolutionary concept, not a revolutionary concept since it has been introduced and practiced in previous decades as well. The current research paper contributes to educational research based on the investigation of holistic perspectives of the ongoing online teaching activities during the lockdown period. The article is built on a literature review. The methodologies are described and the results are presented. There have been research on distant learning and digitalization, but mostly in terms of potential, obstacles, and student assessments, as well as their influence on education. There are no empirical research on the worldwide trend of how employees utilize e-learning resources to determine instructors’ interest in and attitudes about using them. This chasm is also regarded a new angle of empirical research that uses the Chi-square test of independence to find patterns. The present research aims to build a realistic instrument that can assess instructors’ attitudes about e-learning during COVID-19 with this purpose in mind.The paper consists of two parts: a literature review and statistical analysis. The research was conducted by means of a diagnostic opinion CAWI (Computer Assisted Web Interview) questionnaire and statistical analysis. This study was conducted among 342 teachers working in various universities located in the following countries: Poland, Pakistan, Iraq, USA, UK, Germany, and Austria. The questionnaire consisted of 20 questions. The researchers provided a detailed overview of e-learning practices during the pandemic and its future prospects from the teacher’s point of view. The goals of this article and the research problems are to learn about the worldwide trend of how employees utilize e-learning resources, to identify teachers’ interests in and attitudes towards using e-learning resources throughout the globe, and to recommend opportunities for workers to use e-learning resources around the world, which is a very important issue, especially in the era of globalization, society 5.0, and industry 4.0. The authors also proposed a Chi-square statistical analysis to check whether there exists a relationship between two variables based on which the hypotheses were formulated. The results of the study clearly show that the respondents approach to e-learning was very responsible because they realized that it was up to them to properly convey knowledge. The results of empirical research show that the digitalization of education is no longer a future trend, but today’s trend or even a university standard in the education improvement direction.

The study presents the use of spatial imaging of the shape of the deformation formation area occurring at the point of contact between the burnished tool and the processed material surface in the burnishing process. In the analysis of changes in the shape of surfaces processed by ball and disc pressure burnishing, an integrated measurement station was used to measure surface stereometry (New Form Talysurf 2D/3D 120 by Taylor Hobson) and to carry out a series of axially shifted roundness measurements (Talyrond 365 by Taylor Hobson). The geometric parameters of the deformation zone determined in the direction of the circumference of the cylindrical surface (direction of the main movement) and in the axial direction (in the feed plane) are presented. The data obtained as a result of metrological measurements were analysed using specialized computer software.

The paper presents a computer simulation of the influence of the corner construction of a forming tap on the tool material strain. The obtained visual representation is presented of the course of thread groove formation and the distribution of stresses and deformations in the workpiece and tool. The obtained operational stress distributions allow the observation of places with maximum loads and thus exposed to accelerated wear. This helps to select the most advantageous outline for the tool adapted to the specific application in the technological process without the need for long-term operational tests.

This study analyses a set of phenomena occurring in the burnished surface layer at the initial moment of deformation formation. The aim of the present research was to explain the phenomena occurring in the top layer of the material during burnishing. The presented analyses include selected laboratory and experimental studies of the process involved in forming burnished surface layers. As shown, conducting an analysis of these processes is purposeful and important because the processes affecting final deformations determine the definitive properties of the burnished surface layers. The final results should help to increase the durability and smoothness of the surface of the products obtained. The feasibility of applying computer technology to determine the three-dimensional shape of the deformation zone formation based on measurements of the stereometry of the contact zone of the burnishing tool with the workpiece material is presented. The process of forming a deformation zone was analysed, revealing that irregularities left over from prior treatment are permanently deformed, and a new structure of irregularities is formed on the machined surface, conditioned by the mechanical, geometric, and kinematic factors of the process. Crucial to this are qualities such as the burnishing load (pressure), the type, shape, and dimensions of the tool, the properties of the workpiece material, and the roughness of the surface before burnishing. The analyses presented here include the first stage of processing, in which initial contact is made with the workpiece, and the period of actual processing, during which plastic deformation of the material occurs in three perpendicular directions, leading to the formation of a material wave on the machined surface just in front of the burnishing tool.
