Blockchain for Big Data: Approaches, Opportunities and Future Directions

Abstract: The last several years have seen a significant increase in interest in big data across a range of scientific and engineering fields. Despite having several benefits and applications, big data still has some difficulties that must be overcome for a higher level of service, such as big data analytics, big data management, and big data privacy and security. Big data services and apps stand to greatly benefit from blockchain decentralisation and security features. In this article, we present an overview of blockchain for big data with an emphasis on current methods, possibilities, and upcoming trends. We begin by providing a succinct explanation of big data, blockchain, and the purpose of their integration. After that, we look at different types of blockchain assistance for big data, such as blockchain for security in big data collection, data privacy protection, storage, and collection. Next, we examine the latest work on the utilization of blockchain applications for big data across different industries, including smart grid apps and applications, smart city applications, and smart healthcare applications. A few illustrative blockchain-big data initiatives are given and discussed for a good understanding. Finally, difficulties and potential directions are examined to advance research in an exciting field.

Social Networks as Emblematic of Children’s Communication Interaction

In this article, the key attention is paid to the problem of the potential dependence of the children‘s audience on participation in social networks. Having defined as the purpose of the article the need to specify the elements of communication dependence of children on participation in social networks, a significant material of specific studies of the interests of the children‘s audience in social networks of both theoretical and applied nature, conducted by Ukrainian and foreign scientists, was elaborated. It is emphasized that the Internet and such a significant factor in its functioning as social networks are an extremely useful social factor in the intellectual, social and cultural growth of children and young audiences. At the same time, social networks are such a mass communication environment, within which there is always a potential danger of attracting children and young audiences to dishonest, and often socially critical groups and communities. The deviant content of such social networks as Twitch, YouTube, Instagram, TikTok, Discord, Roblox was analyzed. A generalized algorithm for determining the key, emblematic characteristics of dangers for children in social networks is derived, recommendations are given for reducing the level of both children‘s dependence on social networks and absolute trust in the content transmitted by social networks.
Feature Based Indian Currency Detection Using Minimum Weight Distance Classifier

The Automated Currency Recognition is of great interest as a number of automated banking systems used by financial institutions make use of it as their main function. A review of the literature on banknote recognition, however, reveals that there are no methods that have been proposed or put into practice for the identification of recently issued bank notes. Real-time applications can benefit from the suggested approach's excellent performance and relative time efficiency. We believe that the composite feature described in this thesis which combines elements of both color and texture is a first in the field of banknote identification. Our contribution is that this research initiative and the suggested technology have made real-time recognition of recently released ultimate development of real-time multi-currency recognition is made feasible by banknotes.
Digital Humanities Projects

The author considers the Digital Humanities as a tendency towards a constructive synthesis of computer technology and humanitarian science in the context of their claim to make a paradigm shift in the humanities. As part of this review, the author raises a question about the role of interactive multimedia tools in the humanities, and tried to evaluate the novelty and content that scientific and educational projects receive with their help. The author develops and justifies the principle of systematization of Digital Humanities projects, based on the priority of distinguishing projects by the nature of the relationship between their humanitarian and computer (technological) components. Considering both the actual digital projects and the academic publications devoted to them in the context of their systematization, the author observes that many projects are largely experimental in nature due to the use of ever new multimedia tools, so it is premature to talk about a meaningful transformation of humanitarian science. Focusing on the issue of a successful synthesis of digital technologies and the humanities, the author notes that new technological tools (multimedia, AI or neural networks, etc) allow raising new questions, updating additional objects of research and creating new methods. However, new tools do not always set the completeness of the new content, only supplementing it, and the acquired interactivity does not always directly work for scientific character. In this case, we face with the reverse situation, when the claims of technologically determined disciplines to be scientific are intertwined with the claims of disciplinary science to manufacturability. As a result, the author concludes that the direction of Digital Humanities is significantly influenced by technoscience with its dissolution of the boundaries between fundamental and applied research and the desire for new technologies that transform the processes under study, which makes McLuhan’s concept especially relevant.
CONCEPT OF DESIGNING A VIRTUAL EDUCATIONAL SPACE WITH THE POTENTIAL FOR THE ADULT`S SUBJECTNESS DEVELOPMENT

The purpose of the article is to present the psychological concept of designing virtual educational spaces developed in the Laboratory of Modern Information Technologies of Education of G.S. Kostiuk Institute of Psychology of NAES of Ukraine, which provide the necessary psychological and pedagogical resources for the development of adults’ subjectivity. Research methods. Theoretical and methodological analysis of the problem. Results. The main theoretical and methodological provisions of the concept are defined, among which are the concept of virtual educational space, as well as the concept of subject, subjectness and field of subjectness in the context of virtual space, issues of systemic organization of activity of all subjects of the educational process. The concept of designing and its interpretation in the aspect of design of virtual educational space is introduced. As a leading psychological aspect of designing student activity, designing a learning community is considered. Specific digital technologies for designing a virtual educational space as an integral digital metatechnology are defined. Conclusions. The article shows that virtual educational space should be interpreted as an integral psychological and pedagogical metatechnology that systemically organizes the activity of all subjects of the educational process. It is found out that the theoretical and methodological foundations of designing a virtual educational space for the adults` subjectness development are design-technological paradigm and concept of hierarchical designing. It is proved that when organizing group work of adults in designed virtual educational spaces it is advisable to take into account the peculiarities of group dynamics that takes place in such a space. Integral use of specific digital technologies in designing a virtual educational space should conceptually correspond to the designed system of relevant psychological and pedagogical technologies.

Progress of Science and Interfaces of the World

In this article, I want to show that the concept “rationality”, which is important for the French school of epistemology of science, has a dual content and is not very successful. This is the main point of my polemic with Tatyana Sokolova. On the one hand, there seems to be general rationality in it, understood as a preference (in the broad sense) for benefits over costs. Benefits include true knowledge. On the other hand, there is a historical socio-cultural context in which scientific knowledge arises and in which the parameters of practice are determined, which serves as the final instance for testing knowledge. At the same time, there are many such contexts in society, which I call human interfaces. The world, for its part, offers many of its interfaces as collections of interaction tools. When some interface of a person and some interface of the world assimilate each other, knowledge arises, that is confirmed by practice. It can be considered rational. But with a change in the sociocultural context, the human interface also changes, so that a search for new assimilation takes place. It is carried out by science. I agree with Tatyana Sokolova’s characterization of the progress of science, but I suggest at least differentiating the levels of rationality. One operates in the historical sociocultural locus, the other ensures the change of such loci and the adaptation of knowledge to them. I consider the progress of science to be an evaluative characteristic; no objectively recorded phenomenon corresponds to it. The disciplinary distinction of science is derived from the concepts of “object” and “method”, which have a performative content.

Functions in R

In this chapter, we cover how to write functions in R. If you already know much of what is covered, feel free to skip ahead. We will discuss the way parameters are passed to functions as “promises,” a way of passing parameters known as lazy evaluation. If you are not familiar with that but know how to write functions, you can jump forward to that section. We will also cover how to write infix operators and replacement functions, so if you do not know what those are, and how to write them, you can skip ahead to those sections. If you are new to R functions, continue reading from here.
Auto-numbered list continuations

Pandoc’s Markdown allows for “fancy lists”, i.e., lists with different styles used for the marker of ordered list items. E.g., the list (I) primus (#) secundus (#) tertius uses uppercase roman numerals and double parentheses for the markers. It gets rendered as primus secundus tertius Continuations The fancy lists feature also allows to continue lists after an intermediate paragraph: i. one #. another Interruption; not part of any list. iii. continue #. keep counting This...
ART THERAPY AS A MEANS OF EDUCATIONAL WORK IN EDUCATION

The article reveals the essence, tasks, and functional capabilities of art therapy, elucidates the specifics of its use in the conditions of modern educational institutions of Ukraine. In modern society, interest in art therapy as a method of healing through creativity is growing. Art therapy sessions have a significant impact on the development of social communication skills and positive social and psychological traits of a person. Now we use new methods of value education of children and youth, turn to innovative educational and developmental technologies that are formed on the border of various scientific fields. The issue of finding new ways to improve the quality of education at the time of the democratization of education is discussed. Special attention is paid to the development of new educational technologies. In the education of the personality, the main thing in behavior is compliance with social norms. Much attention is paid to personally oriented education, that is, it is necessary to encourage the child to self-discovery and self-activity. The role and pedagogical conditions of the use of art therapy technologies in the teacher's work with the aim of creating a comfortable environment for the formation of a comprehensively developed personality are substantiated. It was determined that the pedagogical direction of art therapy is designed for a potentially healthy personality, connected with strengthening the child's physical and mental health. It is most urgent now to use new, non-standard methods of education of modern youth. It is art therapy that is an adequate methodological basis for solving educational and psychocorrective tasks. Art therapy helps to understand and evaluate one's feelings, memories, images of the future, therefore it is a unique way of communication of a person with himself.
A Sentiment Analysis Hybrid framework for recognizing Sarcasm and Negations in User Generated Content: The case of Greek Language

A Sentiment Analysis Hybrid framework for recognizing Sarcasm and Negations in User Generated Content: The case of Greek LanguageThe development of the World Wide Web 2.0 has allowed users to upload, share, and exchange their opinions or ideas on various topics on a plethora of websites.As a result, a large volume of data is generated that contains useful information about consumers' preferences from various sources, such as micro-blogs, reviews in digital marketplaces, discussion forums, and more.In research, various methodologies are presented to address the specific problem with the Sentiment Analysis to be the preferred one.Two techniques have also dominated: the machine learning techniqueand the semantic orientation technique.Additionally, three levels of analysisare presented: the text level,the sentence level,and the aspectlevel.Several frameworks have already been proposed that use machinelearning techniques, while the same level of interest is not shownfor the semantic orientation technique.Limited research is also presented in the recognition of sarcasm and negations, especially in user-generated content.It is worth noting that sarcasm is considered an advanced form of speech and is characterized as an important research field in Sentiment Analysis and in Natural Language Processing in general.The purpose of this research is to presenta hybrid frameworkusing the machinelearning technique and the sentimentorientation approach of Sentiment Analysisfor detecting the sarcasm and the negationin opinionative sentences in Greek language.The framework is tested in a dataset that contains 80,000 customers' reviews written in Greek Language and the findings will be practical and significant, as not enough attention has been paid to Natural Language Processing techniques and tools used in combination with non-English, like the modernGreek language.As future work, the framework will be implemented in English Language.
Formally verifying Kyber

In this paper we present the first formally verified implementations of Kyber and, to the best of our knowledge, the first such implementations of any post-quantum cryptosystem. We give a (readable) formal specification of Kyber in the EasyCrypt proof assistant, which is syntactically very close to the pseudocode description of the scheme as given in the most recent version of the NIST submission. We present high-assurance open-source implementations of Kyber written in the Jasmin language, along with machine-checked proofs that they are functionally correct with respect to the EasyCrypt specification. We describe a number of improvements to the EasyCrypt and Jasmin frameworks that were needed for this implementation and verification effort, and we present detailed benchmarks of our implementations, showing that our code achieves performance close to existing hand-optimized implementations in C and assembly.
RAFA: Redundancies-assisted Algebraic Fault Analysis and its implementation on SPN block ciphers

Algebraic Fault Analysis (AFA) is a cryptanalysis for block ciphers proposed by Courtois et al., which incorporates algebraic cryptanalysis to overcome the complexity of manual analysis within the context of Differential Fault Analysis (DFA). The effectiveness of AFA on lightweight block ciphers has been demonstrated. However, the complexity of the algebraic systems prevents it from attacking heavyweight block ciphers efficiently. In this paper, we propose a novel cryptanalysis called Redundancies-assisted Algebraic Fault Analysis (RAFA) to facilitate the solution of algebraic systems in the setting of heavyweight block ciphers. The core idea of RAFA is to expedite SAT solvers by modifying the algebraic systems, which is accomplished via two methods. The first method introduces redundant constraints, which is proposed for the first time in the context of algebraic cryptanalysis. The second one is a sophisticated linearization of the nonlinear Algebraic Normal Form (ANF). It takes RAFA for about 9.68 hours to attack AES-128. To the best of our knowledge, this is the first work that uses a general SAT solver to attack AES with only a single injection of byte-fault. Moreover, RAFA can attack AES-128 in 50.92 and 27.54 minutes for nibble- and bit-based fault model, respectively. In comparison, the traditional DFA algorithm implemented by pure C takes 4 ~ 5 hours under all three fault models investigated in this work. Moreover, in order to show the generality of RAFA, we also apply it to other heavyweight block ciphers. The best results show that RAFA could recover the key of Serpent-256 and SPEEDY-r-192 in 20.7 and 1.5 hours using only three faults, respectively. In comparison, AFA could not break these two ciphers even when 30 bits and 50 bits of their keys are known, respectively. Furthermore, no DFA work on Serpent or SPEEDY is known using comparable fault models.
