Nowadays, big data influences many aspects of human life. They help in medicine with diagnosing different illnesses, in traffic with watching of traffic accidents, and of course, they have a crucial role in supporting decisions. It is appropriate to test another database, respectively, another database type, in every operation's unsatisfactory performance by using a set database. A transformation process is needed in this case. Big Data entering this database has a different structure and size, which influences the set transformation process's time difficulty. The transformation process changes the data structure, from relational to nonrelational, respectively nonrelational to a relational database, making it possible to stop the process or an error that can end up with an incomplete change of a data structure and the data this process must have been repeated. “Version” system we created in this paper is, in the case of incomplete data change, respectively failure of transformation process during the transformation of a relational database to a nonrelational or nonrelational database to relational, capable of continuing from the error point of the previous approach, and so it can erase necessity to perform whole transformation process from the very first beginning.

Blended learning represents a combination of face-to-face instruction in a classroom and e-learning. In several studies, we proved that it is a suitable method for teaching mathematics at our faculty. However, in a summer term of the academic year 2019/2020, it was not possible to have face-to-face lessons due to a pandemic situation caused by COVID-19. Thus, we have to use only e-learning. In the paper, we compare the results of the students taught by blended learning and e-learning and we prove that e-learning helps to reduce the negative impact of COVID-19 in teaching mathematics. Moreover, we declare that there is no significant difference between the results of daily and external students in the final tests.

This study focuses on the use of Apple iPads in lessons in primary schools in the Czech Republic. Despite the fact that in Western countries, both the manner and the efficiency of the use of iPads in various educational stages are already being researched, there are no such studies thin the context of the Czech Republic. In this regard, this study provides yet unpublished and innovative findings.

In this article we deal with the use of one-parameter machine learning methods for the recognition of DDoS attacks. At the same time, we want to present the implementation of research focused on cybersecurity in the curriculum of our study engineering program Applied Network Engineering. We focused on the autoregressive coefficient of the first order autoregressive analysis and on the Hurst coefficient, which expresses the degree of self-similarity of the observed flow. We tested the ability of the coefficients to detect a change in the structure of the IP flow during a DDoS attack in time on simulated data and subsequently on several recorded real DDoS attacks which were preprocessed by our students.

Crowdsourcing as a new approach in the field of Quality of Experience (QoE) and an alternative to the traditional subjective laboratory testing has become popular and gradually expanded. In recent years several crowdsourcing web-based frameworks have been developed. In this paper we present a web-based crowdsourcing framework developed by multimedia team at our Department of Multimedia and Information-Communication Technology. The paper also deals with a description of term crowdsourcing in a general form as well as in a context of quality assessment. Furthermore, some differences between laboratory and crowdsourcing approaches are written. Moreover, several of the well-known existing frameworks are described.

Teaching formal methods, especially semantics of programming languages is an important aspect of theoretical informatics. The learning process often includes a lot of mathematics and learning different notations, which appears to be very difficult for students. In this paper, we present a new interactive tool for visualization of the structural operational semantics of a simple imperative program. We demonstrate our approach on the example of a simple program, where we visualize the inference process of small steps semantic method.

Education, the educational process is characterized as a purposeful activation of conditions that allow the optimal development of each individual about individual predispositions. Education is a comprehensive process of personality development, which includes cognition, practice and teaching. The aim of the paper is the transfer of new acquired experience, skills and knowledge and especially the change of work behaviour through learning and application of new methodologies. For the student himself, subsequently, the graduate, as well as functioning on the labour market, achieving competition ability, prestige, or obtaining various awards is an influential motivating factor. In the case of the introduction of a new product, it is crucial to cultivate the maintenance and increase of the company's market share and thus satisfy customer demand. Not every product has to satisfy every customer, and therefore the definition of the target market is a critical part of the product at the beginning of the life cycle. Quantitative market research should be carried out at all stages of the design process. Product development is a creative discipline that requires a systematic approach to managing the operations needed to bring a new product to market. The result of innovative concepts and the use of product configurators is applied in almost every single sphere, not excluding the education market itself and the implementation of new methods.

In the recent past, the use of learning management systems has increased as these enable remote education via electronic media, i.e. eLearning. The use of such platforms was further elevated by needs for eLearning due to the COVID-19 pandemic. In order to achieve secure and reliable identity management in eLearning systems, biometric technologies are increasingly deployed for remote student authentication. Numerous researchers proposed concepts and methods on how to effectively integrate biometric recognition into eLearning. This work provides a conceptual categorisation and survey regarding the state-of-the-art of biometric technologies for eLearning along with a detailed discussion on open issues and challenges in this emerging field of research.

The article presents the implementation of the course Management of cybersecurity incidents in the virtual laboratory in GNS3. Topologies in virtual laboratories are actual in today's covid-19 pandemic times, because many universities are forced to use live online or hybrid teaching.

Blended learning is a formal education program in which a student learns at least in part through online delivery of content and instruction with some element of student control over time, place, path, and/or pace and at least in part at a supervised brick-and-mortar location away from home (see [1]). In this paper we present an example of use of blended learning education for the university courses, specifically for the Fuzzy sets courses. These courses are taught on Matej Bel University, Faculty of Natural Sciences, Department of Computer Science. The presented example is being used in the teaching of external students. Since this period is affected by the COVID-19 disease it is useful to be prepared for teaching all of the students with the use of these methods.
