Opis:: The continuous development of production processes is currently observed in the fourth industrial revolution, where the key place is the digital transformation of production is known as Industry 4.0. The main technologies in the context of Industry 4.0 consist Cyber-Physical Systems (CPS) and Internet of Things (IoT), which create the capabili-ties needed for smart factories. Implementation of CPS solutions result in new possibilities creation – mainly in areas such as remote diagnosis, remote services, remote control, condition monitoring, etc. In this paper, authors indicated the im-portance of Cyber-Physical Systems in the process of the Industry 4.0 and the Smart Manufacturing development. Firstly, the basic information about Cyber-Physical Production Systems were outlined. Then, the alternative definitions and different authors view of the problem were discussed. Secondly, the conceptual model of Cybernetic Physical Production System was presented. Moreover, the case study of proposed solution implementation in the real manufacturing process was presented. The key stage of the verification concerned the obtained data analysis and results discussion.

Opis:: O cyberzagrożeniach łatwo mówić, gdy doszło już do incydentu bezpieczeństwa. Wówczas dowiadujemy się, że firma musiała zapłacić okup za uzyskanie klucza do zaszyfrowanych przez złośliwe oprogramowanie danych. Biznes na chwilę obniża poziom ciśnienia krwi, a cyberprzestępca liczy wpływy. Jak wynika z rynku zachodniego i badań zajmującej się cyberbezbieczeństwem firmy Infrascale: już 78% małych i średnich przedsiębiorców działających w modelu B2B zapłaciło pierwsze okupy w wyniku cyber ataku.

Opis:: Purpose: The purpose of the article is to present both theoretical and practical basis for cybersecurity in electronic banking in Poland during the COVID-19 pandemic. During this period a major reorganisation of IT solutions occurred, which allowed to extend the range of online products and services offered both to bank customers and employees. As our life is more and more dependent on digital technologies, cyber attacks have become more costly and more dangerous. Driven by dynamic technological development regulations have changed, which resulted in cybersecurity becoming a key priority in financial institutions. All the more so because the rapid technological development has been followed by more and more advanced techniques used by criminals searching for easy financial profits. Methodology: The paper uses the method of literature review - mostly electronic sources, descriptive and comparative analyses. Findings: From customers, perspective, the impact of COVID-19 pandemic on cybersecurity in electronic banking in Poland may be recognized as negative. The years 2020-2021 brought a dynamic growth in the number of digital banking customers, especially mobile banking. In those years financial institutions recorded an enormous increase in online payments, which was the result of strong, forced by the pandemic, surge in sales in E-commerce. At the same time, there was a sharp rise in the crime rate targeted at banks, but most of all, at bank customers. While the security of the very financial institutions remained unthreatened, there was an explosion in the number of cybercrimes targeted at E-banking users, with the losses giving dozens of millions PLN in total. That is reflected by the data provided by the National Bank of Poland, numerous complaints to the Financial Ombudsman, the Office of Competition and Consumer Protection, as well as the police investigations. Practical implications: The analysis of relations between theoretical and practical bases of cybersecurity in E-banking in Poland during the COVID-19 pandemic is a key factor for financial institutions. Cybercrime undermines customers' trust in E-channels and therefore negatively influences how banks are perceived, the level of the users' activity in digital channels, and consequently, activity and sales in E-channels. Besides the image and financial risks, banks need to take into consideration the increase in reputation, operation and legal risks. On these grounds, it is possible for state organisations and financial institutions to develop professional education concerning cybersecurity, not only for E-banking customers, but for the whole society.

Opis:: The text presents a short overview of activities of the Polish Ministry of National Education over the last dozen years or so, with a particular focus on the activities that are the results of planned or already implemented reforms in Polish school in terms of both improving its competitiveness and taking practical steps aimed at teaching practical skills, and not just providing the theoretical knowledge on such topics as new technologies, usage of ICT tools as didactic aids, Internet accessibility, cyber-safety, e-textbooks, or international cooperation projects (for instance eTwinning). The article can function as the base for comparison with the actions of other countries’ governments from our region in this field. The numbers given in this text are to give only the general idea of how many more challenges there are for the governing authorities, education financing system, and the Ministry of National Education. The school does not have to encourage students to use the Internet or multimedia, but it should teach how to use them in a safe and conscious way in order to develop one’s self, qualifications, and competences.
Tekst prezentuje krótki przegląd działalności polskiego Ministerstwa Edukacji Narodowej w ciągu ostatnich dwunastu lat. Szczególna uwaga poświęcona zostaje działaniom, które są rezulta-tem planowanych i już wprowadzonych reform w polskich szkołach w celu poprawy ich zdolności do współzawodnictwa z innymi szkołami, a także wykonania praktycznych kroków w kierunku nauczania umiejętności praktycznych, a nie prostego przekazywania wiedzy teoretycznej z zakresu nowych technologii, wykorzystania narzędzi ICT jako pomocy dydaktycznych, dostępu do Internetu, bezpieczeństwa w sieci elektronicznych podręczników oraz projektów współpracy międzynarodowej, takich jak eTweening. Artykuł może stać się punktem odniesienia dla porównania z działaniami podejmowanymi w tym zakresie przez rządy innych krajów. Liczby przytoczone w artykule dajątylko ogólne pojęcie o tym, jak wiele wyzwań staje przed rządzącymi, systemem finansowania edukacji oraz Ministerstwem Edukacji Narodowej. Szkoła nie ma obowiązku zachęcać uczniów do wykorzystywania Internetu i multimediów, ale powinna nauczać, jak ich świadomie i bezpiecznie używać, aby uczniowie rozwinęli się jako osoby oraz zwiększyli swoje kwalifikacje i kompetencje.

Opis:: The purpose of this study is to evaluate the safety of individuals’ behaviour in the cyber world, especially when using financial services. The article focuses on knowledge of cybersecurity issues, cyber risk awareness and respondents’ self-assessment as potential determinants of individual behaviour. The data obtained from a survey of a representative group of Polish citizens during the second wave of the COVID-19 pandemic was analysed. Ordinal logistic regression and instrumental variable analysis confirm the existence of a positive relationship between knowledge and awareness of cyber risk and safe behaviour in the cyber world. Older generations exhibit safer behaviour which may be linked to their life experience; however, the results do not confirm that experiencing a loss due to cyber risk convinces individuals to use Internet-based solutions in a safer manner. Therefore, educational campaigns should be expanded to include cyber risk issues and tailored to the needs of various users.

Opis:: The authors update the issue disassembly-free control and correction of all components of the error of measuring channels with multi-bit analog-to-digital converters (ADCs). The main disadvantages of existing methods for automatic control of the parameters of multi-bit ADCs, in particular their nonlinearity, are identified. Methods for minimizing instrumental errors and errors caused by limited internal resistances of closed switches, input and output resistances of active elements are investigated. The structures of devices for determining the multiplicative and nonlinear components of the error of multi-bit ADCs based on resistive dividers built on single-nominal resistors are proposed and analyzed. The authors propose a method for the correction of additive, multiplicative and nonlinear components of the error at each of the specified points of the conversion range during non-disassembly control of the ADC with both types of inputs. The possibility of non-disassembly control, as well as correction of multiplicative and nonlinear components of the error of multi-bit ADCs in the entire range of conversion during their on-site control is proven. ADC error correction procedures are proposed. These procedures are practically invariant to the non-informative parameters of active structures with resistive dividers composed of single-nominal resistors. In the article the prospects of practical implementation of the method of error correction during non-dismantling control of ADC parameters using the possibilities provided by modern microelectronic components are shown. The ways to minimize errors are proposed and the requirements to the choice of element parameters for the implementation of the proposed technical solutions are given. It is proved that the proposed structure can be used for non-disassembly control of multiplicative and nonlinear components of the error of precision instrumentation amplifiers.
