The Waste Sorting Education Media: An Innovation with Android-based Game

Knowledge of waste classification and segregation is very important considering that currently Indonesia is one of the largest plastic waste contributor countries in the world. Games that can be modified for educational purposes are educational games, especially in waste sorting. This study aims to develop an android-based waste sorting educational game (with the types of waste that appear in the school environment), as well as how to sort this android-based waste. Educational games are very appropriate as educational or learning media. Researchers use a research and development design or Research and Development Design (R&amp;D) with the Borg and Gall model. In this initial study, it was carried out up to the small-scale user trial stage. The collection of teacher response data as a media user is carried out using an application usability instrument, namely the System Usability Scale (SUS). The research was conducted in 4 elementary schools. The educational game Sorting Trash was developed using Construct 3, Canva and Pixlr. This game is operated with an Android-based smart phone so that it is easily accessible to the wider community. The results of the validity test by media experts and material experts show that the results of the Android-based Sort Waste educational game are very valid, so they are very suitable for use as educational media for elementary school students.
A Study on the Correlation between Self-directed Learning and Classroom Psychological Climate among Undergraduate Nursing Students

Objective: To study the correlation between self-directed learning ability and the classroom psychological atmosphere of undergraduate nursing students. Methods One hundred and sixteen undergraduate nursing students from a college in Pingdingshan City, Henan Province, were selected, and the study was carried out through the Chinese version of the Self-Directed Learning Rating Scale and the Class Psychological Atmosphere Scale. Results The total score of nursing undergraduate interns' self-directed learning ability was (221.43±10.59). The score of the class psychological atmosphere was (151.17±7.92), and self-directed learning ability and class psychological atmosphere were positively correlated (rs=0.793, P=0.000). Conclusion Nursing undergraduates' self-directed learning ability is at a medium level, the class psychological atmosphere is at a medium-high level, and the two are strongly positively correlated, so it is recommended that colleges and universities take direct or indirect ways to improve the class psychological atmosphere and promote students' self-directed learning ability.
The Role of Kalman Gain and Noise Covariance Selection on the Convergence in State Estimation

In state estimation problems, the Kalman filter (KF) algorithm considers the noise in the measurements and the systems facilitating convergence to the true state. This paper presents the Bayesian derivation of the discrete-time KF algorithm for a simple example known as the random walk model. However, if the KF coefficients are not well-tuned, it can significantly impact the estimation accuracy and may lead to algorithmic inconsistency. The Kalman gain is a quantitative measure which plays a crucial role in achieving the optimum convergence and stability. In this study, we evaluate the importance of the Kalman gain in the KF algorithm across several choices of the error covariance within the context of the random walk model. Furthermore, we demonstrate that the optimal Kalman gain is determined by minimizing the mean squared error (MSE), producing an unbiased and efficient estimate. This adaptive adjustment enables the KF to tune parameters easily. The theoretical and numerical investigations were carried out using the random walk plus noise model.
Law and technology: The impact of innovations on the legal system and its regulation

The relevance of this study is due to the introduction of technologies into the legal sphere, as well as their rapid development, which causes the inconsistency of conventional legislation with the emerging social relations. Thus, the purpose of this study was to research the impact of digital technologies on the modern legal society and their legislative regulation to formulate ways to improve and further develop this area. The methods used in this study were the following: historical, comparative legal, statistical, forecasting. The main results of this study are as follows: the concepts of technology, innovation, digitalisation, and artificial intelligence were investigated; the legal regulation of these concepts in both Ukrainian and foreign legislation was examined. The study also identified the main problems and risks associated with the use of digital technologies, including problems related to user security, personal data protection, copyright. Solutions and legislative changes regulating the field of technology were also covered using evidence from the United States of America, Switzerland, Japan, the United Kingdom, Canada. The study analysed the impact of artificial intelligence on the ethical aspects of the work of a lawyer. The study also highlighted the future vision and consequences of the use of technology in various spheres of public life. It was found that digitalisation and the introduction of technology into public spheres of life require flexibility and readiness for change from the legal sphere, as well as the need to strike a balance between innovative changes and the guarantee of fundamental human rights. Considering the international standards that were investigated, it was found that the key area that requires additional protection in the digital age is data privacy and confidentiality. The findings of this study can be used as a basis for improving the legislative framework that governs relations in the field of technology use by lawyers, sociologists, and legislators
Investigating cryptocurrency financing crimes terrorism and armed aggression

The article is devoted to the study of the problems of investigating crimes of financing terrorism and armed aggression with cryptocurrency, which is relevant considering the attack on Ukraine by the Russian Federation, as well as in connection with the significant spread and use of cryptocurrency for financing both terrorism and armed aggression. The purpose of the article is to study the problems of investigating crimes of cryptocurrency financing of terrorism and armed aggression and finding ways and means of solving problematic issues, because cryptocurrency financing of terrorism and armed aggression is an encroachment on national security. The methods of system analysis and technical- legal analysis, as well as the formal-logical method, were used in the research process. Thanks to this, approaches to understanding the way of committing crimes of the researched category have been determined. The shortcomings in the legal regulation of the circulation and use of cryptocurrency in Ukraine, as well as in the legal regulation of the investigation of crimes related to the illegal acquisition and use of cryptocurrency for criminal purposes, including for the financing of terrorism and armed aggression, are highlighted. Jurisdictional problems of criminal prosecution of persons who committed crimes of this category, their high latency due to the lack of proper legal procedures and methods of investigation, have been determined. The need to create specialized units in law enforcement agencies, whose competence will include the detection and investigation of the specified crimes, their active interaction with the Cyber Police, is substantiated. The attention and necessity of introducing a system of constant monitoring of social networks, the Internet, and media and conducting OSINT-intelligence from open sources with the aim of detecting and stopping such criminal activities, tracking and arresting and eventually seizing cryptocurrency, if such an opportunity is available, was emphasized. Practical recommendations for the investigation of crimes of cryptocurrency financing of terrorism and armed aggression have been formulated. The need for international legal cooperation in this area was emphasized; the need to involve specialists in the field of information technologies, programming, and blockchain engineering in the investigation process in general and in specific investigative actions. The requirements for the recording of evidence in the protocols of investigative (search) actions during the investigation of crimes of this category are formulated, in particular, the need for hashing of files is specified. The practical significance of the study is that the obtained results can be used during the investigation of crimes of the studied category
Toward Innovative Recognition of Handwritten Arabic Characters: A Hybrid Approach with SIFT, BoVW, and SVM classification

The goal of handwriting recognition has been a top priority for those who want to enter data into computer systems for more than thirty years. In several fields, the advent of handwriting recognition technology is highly anticipated. OCR technology has made it possible for computers to recognize characters as visual objects and collect data about their unique characteristics in recent years. In particular, several studies in this field have focused on Arabic writing. The use of machines to examine handwritten papers is the first step in the character identification process. The identification of specific Arabic characters is the main goal of this particular investigation. In computer vision, Arabic character recognition is very important since it's necessary to correctly recognize and classify Arabic letters and characters in manuscripts. In this research, an innovative approach based on identifying Arabic character characteristics using BoVW (bag of visual words) and SIFT (Scale Invariant Feature Transform) features is proposed. These features are clustered using k-means clustering to produce a dictionary. Following that, SVM (Support Vector Machine) is utilized to classify the word images in a visual codebook created using these terms. The proposed approach is an innovative method to deal with the difficulties associated with Arabic hand-writing recognition. The utilization of BoVW and SIFT features is expected to enhance the system's robustness in recognizing and classifying Arabic characters. The proposed approach will be experimentally evaluated using a dataset that includes a variety of Arabic characters written in various styles. The results of this study will offer important new perspectives on the effectiveness and practicality of the approach suggested.
Diffracting Alto Saxophones

This article presents a study that utilises a performative research approach, contribut ing to our comprehension of music making by grounding it in Karen Barad's theory of agential realism and expanding upon Donna Haraway's use of the concept of diffraction. The starting point is a lecture performance held in 2022 at the Arts in Action: Urgencies in Art and Art Education, where a piece of music for alto saxophone was coming into being, while the saxo phonist partly played and improvised and partly talked about what she sensed and imagined. With saxophones as a pivotal point, a diffractive field is established by the lecture performance and a concert that took place in 2019. Effects that cross time and space are analysed through two agen tial cuts in the concert in the form of two pieces of music. Empiric material is gener ated through sound and video recordings of the soundcheck and concert, supplemented by research notes and a concert review in the Danish daily newspaper, Politiken . The study aims to contest the anthropocen tric tendency to centre human subjects in the making of music. Instead, it asks what human and nonhuman bodies and materi alities do in the study's music making.
Modern challenges and prospects for the development of remote education: A systematic review of the literature

The events of recent years in the world and Ukraine (quarantine restrictions due to the pandemic and Russian military aggression) directly affect the format of educational services and create the need to introduce online education, which will guarantee all subjects of the educational process the acquisition of knowledge, preservation of life, as well as psychological and physical health. The research aims to conduct a literature review of the peculiarities of online education at the present stage in Ukraine and analyse its main advantages and disadvantages. As a result of a systematic analysis of the literature, the interpretation of the “online education” concept by various Ukrainian researchers and the peculiarities of online learning under martial law were analysed, and a detailed analysis of the main pros and cons of online education in Ukraine was carried out. The context of the new challenges (the coronavirus pandemic and Russia’s full-scale invasion of Ukraine) makes distance learning strategically important for ensuring the provision of educational services and preserving the physical and psychological health of all participants in the educational process. The study confirms the active development of online education in Ukraine, with important improvements in infrastructure, teaching materials and teacher training. The importance of online education in both normal and crises is substantiated, and its advantages and disadvantages are identified. The need to learn how to use these technologies while preserving the value of personal communication in education is emphasised. The studies of foreign scholars are analysed and a comparative analysis of education in crises abroad and Ukraine is carried out. It has been found that online education is a promising and necessary form of education, it is developing very actively and can respond quickly and successfully to the needs of society. The practical significance of the study lies in its contribution to the further development of the field of educational technologies and education reform in Ukraine
Sound generation by entropy perturbations passing through circular orifices

Entropy waves generate sound in the presence of flow gradients. At the exit of a combustor, entropy noise generated by the acceleration of entropy waves may affect thermoacoustic stabilities inside the combustion chamber. The Cambridge EWG experiments measured the noise generated by entropy waves passing through a circular orifice. However, predictions based on isentropic models differed significantly from experiment results. To address this mismatch, a compact, one dimensional model that considers the contraction effects at the throat and the degree of non-isentropic effect of the expansion section has been developed previously. However, this model does not explain the differences in acoustic response between thin and thick orifices. This work considers the influence of the L/D ratio of the holes on the internal flow state and corrects the vena contract a factor corresponding to the thick orifice in the previous model. The results of the modified model are closer to the experiment results than those of the previous model. Both theoretical and experimental results indicate that for orifices with small aperture ratios, the entropy noise reflection coefficient is less sensitive to the variation of the flow contract a factor compared to the acoustic reflection coefficient.
The influence of the style and type of education in the family on the functioning of the child's social intelligence in the conditions of distance education

The article reveals the influence of the style and type of upbringing in the family on the functioning of the social intelligence of a child of primary school age in the conditions of distance learning. It is shown that currently the influence of information technologies is growing rapidly, the so-called "digitalization" of many social spheres is taking place. The remote conditions of the educational environment have various consequences on the psychological state of younger schoolchildren and the functioning of their social intelligence. The educational process in the context of social deprivation is a modern norm. This is where the psychogenic nature of distance learning is born, which directly or indirectly affects its subjects. Accepting modern trends in the development of school education, it is important to emphasize the need to harmonize the conditions of the influence of family upbringing on the functioning of the social intelligence of a child of primary school age, which would help the creative self-disclosure of his personality. The psychogenic aspect of distance education in one way or another makes it possible to increase the experience of self-regulation, space for creative expression and self-realization, conscious encounter with new distance learning conditions. The essence of the harmonization of the learning process in the conditions of a distance educational environment is the adoption of a new learning format, the ability to adapt the style and type of family upbringing in the direction of the formation of the creative potential of the younger schoolboy's personality and the development of his social intelligence. Key words: younger schoolchildren, social intelligence, development of social intelligence, functioning of social intelligence, distance learning, family education, styles and types of family education.
Marketing Management of Leisure Tourism Services between Needs and Desires

The paper presents the results of the study on the need for a different kind of marketing for leisure tourism services starting from the needs and desires of tourists to spend their free time in a pleasant way during a vacation.

Computerization, Aid-Dependency, and Administrative Capacity: A Sudanese Case Study

This chapter describes the challenge of information management in the Sudan, focusing on the problems of aid dependency and development planning. It focuses on the issues that are more closely related to the practical side of computerization efforts, considering some specific challenges of the Sudanese context and offering a number of suggestions for system development in similar settings. The chapter is based on our experiences as technical advisors to the Government of Sudan on two United States Agency for International Development-funded projects in which computerization played a major role. One involved the design and implementation of systems for financial accounting, developmental budgeting, project monitoring, commodity assistance tracking and donor coordination for the Sudanese Ministry of Finance and Economic Planning. The other involved support for the Sudanese National Population Committee in a program of research, policy formulation and education.
CROSS-MOMENTS COMPUTATION FOR STOCHASTIC CONTEXT-FREE GRAMMARS

In this paper we consider the problem of efficient computation of cross-moments of a vector random variable represented by a stochastic context-free grammar. Two types of cross-moments are discussed. The sample space for the first one is the set of all derivations of the context-free grammar, and the sample space for the second one is the set of all derivations which generate a string belonging to the language of the grammar. In the past, this problem was widely studied, but mainly for the cross-moments of scalar variables and up to the second order. This paper presents new algorithms for computing the cross-moments of an arbitrary order, while the previously developed ones are derived as special cases.
