The methods of improving the cyclic codes efficiency constructed on the basis of combinatorial configurations of the type "ideal ring bundles" (IRB) s by three factors – correction ability, power of coding method and complexity of the decoding procedure are considered. The method is based on the principle of combinatorial optimization, grounded on the algebraic theory of ordered integer sequences with a circular structure, all the numbers, as well as all sums of consecutive numbers exhaust the value sofnatural row numbers. Two theoretically grounded approaches to increase of noise immunity of cyclic codes are offered: implementation of optimized IRB-code, as well as monolithic and group one. Optimized cyclic IRB-code favorably differs from the rest of the codes of this class by the highest correction capacity at the same length of code words. Optimized IRB-codes constitute a large group of cyclic codes designed on a combinatorial models with selection of corresponding relationships between the parameters of the code to achieve its specified technical characteristics. Noise protected monolithic and group codes belong to the group of self-correcting codes with a ring structure and probabilistic assessment of the level of noise protection. This property allow so instant lydetect a particular part or all invalid characters in the code word by the majority principle. Mathematical calculations have been performed to calculate the optimized ratios between the parameters of cyclic IRB-codes, under which they reach maximum correction capacity. The algorithm of constructing and increasing the power of coding methods of optimized noise-resistant IRB-codes is examined and analyzed. The concrete examples of increase efficiency of combinatorial optimization cyclic codes methods with appropriate calculations and tables are given. The comparative analysis of the IRB-codes with the Golay codes and Bose – Chaudhuri – Hocquenghe (BCH) codes with respect to correction ability, power encoding method and computational complexity of decoding procedures is carried out. The advantages and disadvantages of cyclic, and ringmonolithic and group IRB-codes in comparison with classical analogues are determined. The prospect so fusing the research results in the problems of information and communication technologies are outlined.

The Impact

This study investigated key factors impacting on blended learning delivery with particular focus on socio-cultural and human-computer-interface issues, in the hope that the outcome of this enquiry might contribute positively towards the empowerment of learners and facilitators alike. The study involved a group of first year students enrolled in a Communications Skills Course offered by the (then) Department of English and Communication at the Durban University of Technology. The PRINTS Project, a webquest around which the course activities were based, provided an example of a blended delivery course in practice. While the teaching paradigm used in the course was constructivist, the research orientation employed in this project was critical realist. Critical realism focuses on transformation through praxis and also lends itself to modelling, which provides a way to understand the factors at play within a social system. In the preliminary stages of the research, an exploratory empirical (i.e. applied) model of blended learning delivery was formulated from a theoretical model of course delivery in order to assess which factors in blended learning were systemic and which were variables. The investigation then sought to uncover key factors impacting on the blended delivery system, utilising both quantitative and qualitative methodologies. The findings were analysed in terms of the empirical model to gain an understanding of any factors that might be seen to either enhance or inhibit learning in blended delivery mode. The result was that certain core issues in blended learning and teaching could be clarified, including the use, advantages and disadvantages of information and communication technologies (ICTs) in a learning environment. The notion of the digital divide could also be reconceptualised, and the relationship between literacy (be it academic, professional or social), power and culture could be further elucidated, drawing specific attention to the South African educational environment. The notion of iv culture and its relevance in a blended delivery environment was also further clarified, since the findings of this research project suggested how and why certain key socio-cultural factors might impact, as both enhancers and inhibitors, on the blended learning delivery system.

This article is aimed at demonstrating the possibilities of using the usability testing method in the framework of research to determine the features of the new forms of digital urban participation by Russians in solving social and environmental problems and conflicts. In particular, the authors investigated the effectiveness of environmental online platforms in the UX research methodology through usability testing of these sites from the perspective of their users. The results of testing showed that both the functionality of these platforms to involve the population in environmental practices and technical limitations prevent users from putting environmental initiatives into practice. The data obtained in the framework of the UX study will allow us to compare the perception of users of online platforms with the conceptual vision of their developers to identify potential biases in the perception of these products by their ideologues and users in order to minimize these gaps. In terms of the increase of scientific knowledge, this study will allow to assess the effectiveness of the use of information and communication technologies (ICTs) for digital ecoactivists in comparison with traditional (offline) forms of urban participation, to analyze the new strategies and forms of digital participation, and to identify the main advantages and disadvantages of ICTs in minimizing socio-environmental problems and conflicts in the tradition of M.

Distance learning is the process of acquiring knowledge, abilities, skills and methods of human cognitive activity, it occurs mainly through the indirect interaction of participants in the educational process distant from each other in a specialized environment, it functions on the basis of modern psychological, pedagogical and information and communication technologies. In today’s world, distance learning is a must. This was shown by the existing COVID-19 pandemic. The purpose of our work was to present teaching methods at the Department of Orthodontics of the Ukrainian Medical Dental Academy and to determine the advantages and disadvantages of distance education. To present theoretical and practically oriented content, organize independent work and control knowledge during quarantine, the possibilities of distance learning were used using the Google Classroom web service and using the ZOOM platform, Google-meet, which made it possible to use video, photographic materials, tables, control and diagnostic models, panoramic and other images, orthodontic appliances, orthodontic instruments. Distance learning technology is flexible than traditional. This is its advantage. It is aimed at those who study, creates a comfortable environment for the applicant for higher education to master the material 24 hours a day, 7 days a week. Distance learning allows you to move away from the traditional system of teaching educational material. However, this teaching methodology requires a high level of teacher training. The teacher must have modern pedagogical and information technologies and be psychologically ready to work with applicants for education in a new educational and cognitive environment. The distance form of education must correspond to the methods of teaching in higher medical school. So, the material and technical clinical base of the Department of Orthodontics of the UMCA allows you to provide high-quality online training. But the spread of COVID-19 leads to day-to-day changes in all spheres of life, including healthcare, and the education system.

It goes without saying that the advances of Information and Communication Technologies have brought many changes in various forms of traditional commerce including gambling industry. Nowadays, e-gambling has dramatically changed the way of wagering and is considered as one of the fastest growing sectors of contemporary e-commerce. Every day even more individuals are moving from terrestrial to online gambling venues or start wagering exclusively online taking advantage of the numerous playing options. Characteristically, the global internet gambling gross market is expected to exceed US$51 billion by 2018. Consequently, its dynamics has forced many researchers to investigate e-gambling scientific field from different perspectives trying to gain an improved insight into gamblers behavior in the cyberspace. This chapter aims to investigate the perceived advantages and disadvantages of terrestrial versus online gamblers towards e-gambling activities focusing on university students. Furthermore, it aims to identify possible similarities and differences between the two groups examined.

Nowadays, information and communication technologies (ICT) are being used in the mental health field to improve the quality of the services provided. Several studies refer both advantages and disadvantages for these practices. E-therapy appears as a new way to help people in their life and existing relationships, and there is proven evidence that online therapy helps, for instance, to reduce depression symptoms. It is also seen as a complement of the technological and traditional techniques, to improve the effectiveness and efficiency of the therapeutic process. As a matter of fact, some people tend to be more comfortable with the computer than in face-to-face therapy. Besides patients and physicians, other direct players could be found in this domain, namely, families and caregivers. All players will be directly affected by the use of existing services and thus, a correct assessment of the effectiveness of e-therapy solutions and studies is required. eSchi is a multimedia portal that enables an e-therapy setting for schizophrenia patients. Currently under development, the system is described and future trends in the area are depicted.
