This study deals with a methodology for increasing the efficiency of dynamic process calculations in elastic elements of complex engineering constructions. We studied the complex dynamic processes in a simple engineering construction, a mechanical system of an elastic body–continuous flow of homogeneous medium. The developed methodology is based on the use of a priori information on some of the vibrations forms, the construction of a “simplified” mathematical model of system dynamics, and the obtaining of an analytical relationship that describe the overall range of factors on the elastic vibrations of system. The methodology is used for cases of complex vibrations of elastic bodies, and the obtained results can serve as a basis for choosing the main technological and operational parameters of elastic elements of mechanisms and machines that perform complex vibrations. The results obtained in this work are the basis for calculating the blast effect on the elements of protective structures in order to increase their protective capacity by improving the method of their attachment or by using additional reinforcement, buff load effects on the elements of drilling strings and dynamic processes that occur during surface strengthening by work hardening in order to avoid resonance phenomena, and technological processes of vibration displacement or vibration separation of granular media.

The COVID-19 pandemic and lockdowns resulted in an unusual increase in electronic commerce not only in the conditions of the Slovak Republic. This fact also causes many unanswered questions in business practice, which bother entrepreneurs in ecommerce, especially in the context of consumer protection. The main goal of the article is to examine the current possibilities of electronic commerce in the conditions of the Slovak Republic and especially its limits in the context of consumer protection as a weaker part. Determining the goal of a scientific studye conceived in this way responds to the current practical problems in the business practice. Due to the nature of the researched topic, we have applied analysis, synthesis as well as comparison of legal regulations in the processing of this issue. However, in addition to the mentioned scientific methods of research, we also used scientific literature, case law and analogy of the law. In our scientific article, we strive for qualified answers to the needs of business practice. In conclusion, we critically point out the application problems we have identified and we proposed legislation.

Fact-checking and journalists professional standards usually are considered to be the best fail-safe against manipulations in media. However, we found that newsmakers are able to manipulate even the audience of so-called ‘high-quality media’ who practice all mentioned approaches. To prove this we have refined the concept of ‘pseudo-event’, introduced by D.J. Boorstin, by defining the term ‘fake newsworthy event’ as an event created by newsmakers, that is high-profile and attractive for media, but the only or particular aim of these actions is an agenda-setting, and this aim is not obvious from the origin of the action. Namely, the member of parliament may file some bill realizing that it cannot be adopted and trying just to shape the public opinion. Or some person may claim against a celebrity or businessman having no chance to win at trial. On the example of Ukrainian ‘high-quality media’ we showed that journalists usually do not take into account whether some topics are launched just for manipulating agenda-setting. To prove that we gathered the data about publications focused on such topics in Ukrainian ‘high-quality media’, we provided their discourse analysis, and compared the result with experts’ evaluations of ‘media quality’ and ‘artificiality rate’ of the topic. We have not found correlations between ‘artificiality’ of the topic and the number of publications. Recommendations were elaborated for the media workers if they want to avoid this type of manipulation.

The Covid-19 crisis lockdown caused rapid transformation to remote working/learning modes and the need for e-commerce-, web-education-related projects development, and maintenance. However, an increase in internet traffic has a direct impact on infrastructure and software performance. We study the problem of accurate and quick web-project infrastructure issues/bottleneck/overload identification. The research aims to achieve and ensure the reliability and availability of a commerce/educational web project by providing system observability and Site Reliability Engineering (SRE) methods. In this research, we propose methods for technical condition assessment by applying the correlation of user-engagement score and Service Level Indicators (SLIs)/Service Level Objectives (SLOs)/Service Level Agreements (SLAs) measurements to identify user satisfaction types along with the infrastructure state. Our solution helps to improve content quality and, mainly, detect abnormal system behavior and poor infrastructure conditions. A straightforward interpretation of potential performance bottlenecks and vulnerabilities is achieved with the developed contingency table and correlation matrix for that purpose. We identify big data and system logs and metrics as the central sources that have performance issues during web-project usage. Throughout the analysis of an educational platform dataset, we found the main features of web-project content that have high user-engagement and provide value to services’ customers. According to our study, the usage and correlation of SLOs/SLAs with other critical metrics, such as user satisfaction or engagement improves early indication of potential system issues and avoids having users face them. These findings correspond to the concepts of SRE that focus on maintaining high service availability.

This scientific study focuses on the assessment of the legislation on land valuation, which takes place in the framework of selected administrative procedures in the Slovak Republic. The issue of land valuation is regulated in several pieces of legislation and, in terms of content, is their unifying feature of the valuation of land for public purposes. The reason for examining the determination of the so-called “administrative price of land” is the fact that, in practice, the administrative procedures analyzed are extremely time-consuming and considerably inefficient compared to other administrative practices. Another reason for analyzing the legislation on land valuation is the fact that they also have a direct impact on the speed of the related administrative procedures and on the use of land for private purposes and, therefore, on the actual exercise of the property rights to which the parties to those proceedings are legally entitled. The main objective of this study is to examine the quantity, quality, and differences of legislation allowing land valuation for land consolidation purposes and to compare it with land valuation for restitution and expropriation purposes. In the processing of the topic, we primarily used the method of critical legal analysis and suitable and available scientific methods designed for law examinations, such as description or synthesis. In the context of the examination, we also applied a comparative method to compare the development of the legal situation of the Slovak Republic with the Czech Republic. We also used scientific and doctrinal interpretations associated with the application of case law on Slovak and Czech legislation, as well as professional and scientific literature contained in the Web of Science and Scopus databases. The results of the study indicate that, despite the multi-annual effectiveness of the legislation, it would be appropriate to resolve the problems encountered in the Slovak Republic by adopting a new code regulating the issue of land consolidation.

The scientific paper deals with a part of the business sector, which is made up of family businesses. The paper presents the current status of such businesses from the perspective of positive and negative factors which will be linked to the problem areas. In this article, we have focused our attention on some aspects of family business, especially the managerial aspects, because the management of a family business has various differences and specifics compared to other types of businesses. In the theoretical part, we present the current state of the issue, while the empirical part of the article is based on a survey conducted among family businesses using a questionnaire. This article does not aim to highlight the contentious areas of family business. However, it brings valuable findings of business practice. More than 400 enterprises were approached, the resulting sample consisted of 185 family enterprises. Therefore, we understand the results as a case study from Slovakia. Our findings were subject to statistical analysis using several quantitative methods (t-test, regression models) and we present them in the empirical part. Based on our results, we bring the most valuable findings and ideas for further research.

In this article, we have explored methods for the strategic management of web projects. By introducing a long-term web project development strategy into the operation of a web project, mechanisms can be developed to improve the efficiency and effectiveness of the web project. An important factor is to develop a strategy taking into account all possible crisis situations and ways out of these situations. The authors analyzed and simulated the web project structure, working out methods of web project strategy realization and implementation in a crisis situation. Additionally, in this article, the authors have presented the model for the strategic map of the balanced scorecard of a web project. The authors tested the developed methods on six web projects of university departments. The received results confirmed the appropriateness and necessity of the development and implementation of methods of the strategic management of web projects.
