Modern trends in physics education in Ukraine: integration of technologies and methods to increase effectiveness

The importance of the development of physical education cannot be doubted, since it is the key to the health of the nation and the building of a harmonious society as a whole. Modern realities of life in Ukraine, unfortunately, require not only the appropriate level of education, but also the consideration of additional negative factors affecting a person, his opportunities and needs. The main problems concern the general decrease in the physical activity of education applicants, the forced distance learning format, the lack of conditions for full-time physical education and sports. Nevertheless, this should not affect the quality and efficiency of education, which has caused attention to innovative technologies and approaches in education. There is an urgent need to develop educational and methodological support that will take into account the conditions of obtaining education, possible health risks for their maximum prevention, the potential of innovative technologies when mastering the discipline, the modern domestic experience of introducing new methods of training and directed physical development. The purpose of the article is to systematize innovations in the field of physical education in Ukraine to increase its effectiveness. The following general features of the development of physical culture in Ukraine were determined: striving for a healthy lifestyle and self-improvement among young people; craving for non-traditional sports; the desire to get certain results in sports, that is, persistent internal motivation. All this must be taken into account when drawing up educational and training programs that can really contribute to the development of physical capabilities, the identification of interest in various sports and physical activities, depending on the preferences and level of training, the state of health of the applicants for education. Innovative practices in the field of physical education must take into account the conditions of obtaining education. Therefore, innovations with the use of modern communication technologies, which allow to study independently, while receiving full informational support and control of the teacher, additional motivation from his side, are relevant at the moment. The emphasis in the methodology of theoretical training has shifted towards taking into account the possible risks of injury when performing exercises. This is mainly due to the distance learning format. It is important to provide applicants with all the information about the technique of performing exercises, possible mistakes and their consequences, to foster a responsible attitude to the training process. The introduction of modern communicative practices will contribute to encouraging students to physical development, a healthy lifestyle, independent additional classes, will allow you to correctly choose an interesting, necessary and affordable physical activity for yourself. Further development of this topic can be a detailed study of the methods of organizing the educational process taking into account the peculiarities of the introduction of innovations. The practical development of the experience will be the implementation of the formed programs and the determination of their effectiveness.

On the Need to Develop a Federal Program to Optimize the Economic Base of Public Control in Russia

Annotation. This article is devoted to the analysis of the prospects for the development and adoption of a federal program aimed at optimizing the economic basis of public control in the Russian Federation. The authors substantiate the position that one of the main problems hindering the development of public control in the country is its weak economic base. Due to the fact that public authorities play an important role in the process of formation and functioning of subjects of public control in Russia, the basis for financing the organization and activities of public control are funds from state and municipal budgets. In this regard, the authors substantiate the need for the development and adoption by the Government of the Russian Federation of a comprehensive federal program dedicated to strengthening organizational, technological, material and property independence and independence of subjects of public control. The work substantiates the need to include in the draft of the above-mentioned federal program sections devoted to: ensuring the material and technical independence of subjects of public control from public authorities; ensuring their financing primarily from protected items of public budgets; development of processes for the use of modern information and communication technologies by these entities; consolidation of a system of criteria for assessing the effectiveness and efficiency of the work of subjects of public control as the main condition for increasing the volume of their funding; consolidating a system of control on the part of public authorities regarding budget financing of the activities of these entities; systems for organizing public-private partnerships in the field of public control. In addition, the work substantiates the system of proposals for participation in the development of the above-mentioned federal program of the country's Public Chamber.

Novel intrusion detection system based on a downsized kernel method for cybersecurity in smart agriculture

Smart farming aims to ameliorate the quantity and quality of farms products using modern information and communication technologies. Agriculture has always used cutting-edge technology to improve profitability, efficiency, and safety as well as creating the opportunity for more environmentally friendly operations. In smart agriculture network communication between smart devices is necessary to managing the agriculture process. Consequently, the possibility of information being exposed to hacking is very likely, which makes the information security system extremely important and cannot be neglected. Even though many solutions have been developed to overcome cyberattacks in smart networks, some limitations are observed, such as solving multi-class problems, high feature dimensions, and overhead computation. To address the aforementioned issues, an intelligent Intrusion Detection System (IDS) for identifying cyberattacks in the Internet of Agriculture Things (IoAT) is proposed. The developed model uses a proposed reduced kernel method, the Downsized Kernel Partial Least Square (DKPLS) to extract and reduce data feature dimension to improve detection performance. The DRKPLS approach is used to reduce the dimension of a kernel matrix generated using the Kernel Partial Least Square (KPLS) technique by selecting the most important features. In classification phase, the Kernel Extreme Learning Machine (KELM) is used to classify data for binary and multi-class classification. The proposed IDS is evaluated on a new Industrial IoT Dataset, X-IIoTID. The developed approach achieved higher performances for binary classification and for multi–class classification compared to others machine learning and deep learning approaches. The proposed approach achieved an accuracy rate of 99.92% for binary classification and 99.99% for multi–class classification. Furthermore, the higher percentage in multi-class classification is obtained for the two types of attacks Ransom Denial of Service (RDoS) and Command_Control respectively.

Digital human rights: doctrinal principles

The authors note that the digitization of public services has taken place, which has led to the transition of most or at least a significant number of public services to an electronic format and allowed us to talk about the emergence of concepts of electronic state (government) (e-government). The step-by-step transformation of state data management based on digital technologies, the development of complex super-services for citizens and businesses to receive public services in one click (DIY) was called «digital public administration». However, a clear definition and framework of the concept of «digital human rights» has yet to be developed. They seem to cover all human rights in the context of digitization and the development of modern information and communication technologies. It can be considered that this is the field of information law, which regulates human rights related to the use of information technologies. This includes the regulation of relations in the field of personal data processing, publication of information on the network, processing of big data, application of artificial intelligence, etc. The purpose of the scientific article is to consider the concept of digital rights and their implementation in the Ukrainian and European legal space, taking into account the contribution of Ukrainian scientists. The digital revolution that has swept the world has significantly changed the way people communicate, work and live. However, this rapid technological development brings with it new challenges for the protection of human rights. This article examines the concept of digital human rights and their dimensions in the Ukrainian and European context. It is indicated that the study and protection of digital human rights in the modern world requires a comprehensive approach, taking into account both Ukrainian and European experience. The works of domestic scientists testify to the urgency of the problem and indicate the need for further research in this area. Digital human rights are becoming an integral part of modern society, where technology is rapidly changing the way we live and interact. Ukraine, like other countries, faces many challenges in the field of digital rights, which are caused by the rapid development of information and communication technologies. From this context: first, understanding digital rights and their importance becomes a necessity for every member of society. People should be aware of their rights and responsibilities in the digital space, especially regarding the protection of privacy and personal data; secondly, the development of digital rights in Ukraine should take into account the best practices of European countries and global standards. Improving legislation, increasing public awareness and developing cyber defense are aspects that require immediate attention; thirdly, the importance of cooperation between the state, citizens, business and the scientific community. Effective and sustainable solutions to ensure the digital rights of Ukrainians can only be created through joint efforts.

Transparent ionic liquid antenna based on multi-modes using multiple feeding structures

With the rapid development of modern wireless communication technology, there is an increasing demand for the functionality of the communication system carried by a single platform. To improve the utilization of the antenna, a multimode liquid antenna is proposed in this paper. The antenna is fabricated using 3D printing technology and mainly consists of a cylindrical dielectric resonator, a coaxial feeding structure, and a slot-coupling feeding structure. By hollowing out the middle of a resin container and filling it with low-loss ionic liquid with stable dielectric properties, a liquid dielectric resonator antenna (DRA) is formed. The various resonant modes (slot mode, HEM11δ, TM11δ, TM21δ, and TM31δ modes) can be excited by introducing different feeding structures. The operating frequencies and radiation patterns can be modulated by mode switching. Simulated and measured results show that the antenna operates in the frequency bands of 2.25–2.76 GHz (20.4 %) and 4.82–5.73 GHz (17.3 %), and the maximum gain can be up to 10.3 dBi. The proposed antenna structure avoids the complex RF control circuit design, which has various applications including 5G/6G communications, transparent electronic devices, and Internet of Things.

Rate splitting with semantics as a generalized multi-access framework for intelligent reflecting surfaces

The rapid advancement of modern communication technologies necessitates the development of generalized multi-access frameworks and the continuous implementation of rate splitting, augmented with semantic awareness. This trend, coupled with the mounting pressure on wireless services, underscores the need for intelligent approaches to radio signal propagation. In response to these challenges, intelligent reflecting surfaces (IRS) have garnered significant attention for their ability to control data transmission systems in a goal-oriented and dynamic manner. This innovation is largely attributed to equitable resource allocation and the dynamic enhancement of network performance. However, the integration of rate-splitting multi-access (RSMA) architecture with semantic considerations imposes stringent requirements on IRS platforms to ensure seamless connectivity and broad coverage for a diverse user base without interference. Semantic communications hinge on a knowledge base-a centralized repository of integrated information related to the transmitted data-which becomes critically important in multi-antenna scenarios. This article proposes a novel set of design strategies for RSMA-IRS systems, enabled by reconfigurable intelligent surface synergizing with semantic communication principles. An experimental analysis is presented, demonstrating the effectiveness of these design guidelines in the context of Beyond 5G/6G communication systems. The RSMA-IRS model, infused with semantic communication, offers a promising solution for future wireless networks. Performance evaluations of the proposed approach reveal that, despite an increase in the number of users, the delay in the RSMA-IRS framework incorporating semantics is 2.94% less than that of a RSMA-IRS system without semantic integration.

Sandwich-Structured Mxene/Waste Polyurethane Foam Composites For Highly Efficient Electromagnetic Interference, Infrared Shielding and Joule Heating.

Electromagnetic interference (EMI) shielding and infrared (IR) stealth materials have attracted increasing attention owing to the rapid development of modern communication and military surveillance technologies. However, to realize excellent EMI shielding and IR stealth performance simultaneously remains a great challenge. Herein, a facile strategy is demonstrated to prepare high-efficiency EMI shielding and IR stealth materials of sandwich-structured MXene-based thin foam composites (M-W-M) via filtration and hot-pressing. In this composite, the conductive Ti3C2Tx MXene/cellulose nanofiber (MXene/CNF) film serves as the outer layer, which reflects electromagnetic waves and reduces the IR emissivity. Meanwhile, the middle layer is composed of a porous waste polyurethane foam (WPUF), which not only improves thermal insulation capacity but also extends electromagnetic wave propagation paths. Owing to the unique sandwich structure of "film-foam-film", the M-W-M composite exhibits a high EMI shielding effectiveness of 83.37dB, and in the meantime extremely low emissivity (22.17%) in the wavelength range of 7-14µm and thermal conductivity (0.19W m-1 K-1), giving rise to impressive IR stealth performance at various surrounding temperatures. Remarkably, the M-W-M composite also shows excellent Joule heating properties, capable of maintaining the IR stealth function during Joule heating.

Enhancing spectrum utilization and primary user detection in cognitive radio networks through greedy cooperative spectrum sensing

The utilization of the spectrum is optimized through which primary users of modern wireless communication technologies might obtain a higher chance of detection. The research aims to study how the NI-USRP hardware platform can be used to set up greedy cooperative spectrum sensing for cognitive radio networks. Research primarily deals with energy detection and eigenvalue-based detection approaches, both of which are highly recognized for their capacity to sense the spectrum without having prior knowledge of the primary user signals. In the hardware arrangement, there is one transmitter and two cognitive radio receivers. LABVIEW makes it simple to deploy and maximizes the detection probability across a large sample. Here, it was demonstrated that cooperative spectrum sensing is superior to non-cooperative spectrum sensing, which results in a reduction in the risk of errors occurring during detection. The research discovered that the OR combination rule has a higher detection probability than the AND rule at the same time. The research emphasizes the significance of expanding cooperative spectrum sensing to improve overall detection capabilities. SNRs that are more than 10 dB allow the energy detector to operate, and the eigenvalue detector continues to work when the SNR drops to –9 dB.

“Tektology”, VSM and the digital age

PurposeI examine Bogdanov’s notion of Tektology within the context of modern communication systems and political agendas.Design/methodology/approachThe practicality of Tektology from the perspective of 21st century sensibilities.FindingsI argue that, like the implications of creating a suitable environment in Red Star, the practicality of enabling tektology in the 21st century is unlikely.Research limitations/implicationsTektology was an idea created in the early 20th century and the social conditions of that era-especially in Russia. The work associated with it is Stafford Beers VSM – an idea of combining the two was suggested by Jackson in 2023. Clearly, the early ideas rely on the source material of that era which are taken within the context of now. A mixture of early 20th and 21st century references are referred to. To limit such a topic as this to the word limits of the journal necessitates reducing discussion, for example the link between Tektology and Happiness.Practical implicationsIt is not possible to test these ideas in a practical sense. The discussion relies upon what Tektology proposes and the way in which ICT is used in the 21 century. The only practical attempt of using technology as a major control system is that of Beer’s Chilean project but Tektolgy was more ambitious; it was aimed at creating a new society. The paper can only relate to observations about the way ICTs are used and controlled presentlySocial implicationsThe paper highlights the way that communication platforms are used and controlled in western society and elsewhere.Originality/valueWhile attempts have been made to link Tektology to modern communication technologies few consider it within the context of 21st century cultural, political and media experience.

Drivers of adaptive capacity of rural women farmers: The role of climate action and information mediums in rural Ghana

AbstractGender‐differentiated roles, responsibilities, access, rights, and knowledge gaps shape women's vulnerability to climate change. This is especially critical for women farmers whose livelihoods are climate‐dependent. A key component in building women farmers’ resilience to climate change is deepening their adaptive capacity. Therefore, this research sought to measure the adaptive capacity of women farmers from two unique districts of Ghana using the sustainable livelihood capitals and investigate how access to climate information and the uptake of climate action can influence women's adaptive capacity. Rural women farmers (n = 497) were interviewed through a survey and supported with key informant interviews from six agricultural staff at the selected districts. The adaptive capacity of respondents was rated moderate at 0.405. Differences between the adaptive capacity of women from different agroecological zones (Dormaa East—0.422; East Gonja—0.388) were statistically insignificant (p > 0.05). All climate information mediums except the TV medium had a significant prediction on women farmers’ adaptive capacity. The odds of a decreasing relationship of predictor variables, such as extension officer medium, radio, and adaptation action, require strategic structuring to accrue holistic benefit. The study thus recommends deepening women's benefit from extension services by attracting and retaining female extensionists, while training extensionists on tailored techniques for engaging female farmers. Again, extensionists who report high outreach to female farmers should be incentivized. Traditional and modern Information and Communication Technology mediums must be explored and integrated as alternatives. Co‐benefit practices for both adaptation and mitigation should be encouraged among women farmers to deepen climate action.

Formation of pedagogical skill of future teachers of physical culture by means of mobile games

The article is devoted to the problem of the formation of pedagogical skill among students of higher education institutions. The analysis of the sources proved that the formation of a highly moral personality of the future professional plays an important role in the preparation of a specialist with a higher education. It is natural that the development of a truly civilized society is impossible without the education of patriotic, civic, moral-ethical, cultural-ethical and general human qualities in people. It was found that the purpose of professional training of the future pedagogical community in the context of the requirements is the formation of a high general culture, personal qualities, readiness for independent, creative, personally-oriented pedagogical activity as a humane and culture-forming activity. It has been proven that the future teacher must be able to creatively organize the educational process, carry out scientific research of the pedagogical process, be fluent in the methodology of pedagogy, master new technologies and information systems, and generalize advanced pedagogical and methodical experience. It is substantiated that the quality of education of future specialists remains an important issue and the most important stage in the formation of the future teacher's personality is the first stages of training, when the foundation and base of the specialty is laid, the essence of professional activity is realized.
 It was determined that the educational process in institutions of higher education is characterized by flexibility, adaptability, modularity, economic efficiency, orientation to future professional duties and reliance on modern communication and information technologies. The analysis of the educational program for the training of future physical culture teachers made it possible to find out that a certain distribution of credits for mastering educational components is proposed for the formation of pedagogical skills of students. In order to form the signs of pedagogical mastery, we proposed innovative approaches to mastering mobile games and entertainment. Thus, mobile games in the system of training physical culture teachers contribute to the formation of professional competences in students, which will contribute to strengthening the health of schoolchildren, develop vital motor skills in them, and develop skills in the organization and methods of conducting game material. So, it has been proven that pedagogical mastery is a manifestation of a high result of professional activity, the ability to embody and realize one's own creative potential, combined with effective methods of building the pedagogical process at a high level.

A reality check on the digitalisation of prisons: Assessing the opportunities and risks of providing digital technologies for prisoners

While our societies are developing into digital information societies, most prisoners do not have access to modern information and communications technologies. Smart prisons that provide digital devices for prisoners aim to grant prisoners more autonomy, provide access to education and information, strengthen contact with relatives and friends and reduce the effects of deprivation. The concept of ‘digital rehabilitation’ suggests that digital devices have a positive effect on rehabilitation in various areas. Nonetheless, technological developments also entail risks that go beyond security concerns such as misuse of the devices by prisoners. Based on qualitative interviews with Austrian prisoners and theoretical reflections on the opportunities and risks of digital technologies in prison, we point out ambivalences and possible negative effects for prisoners that have received little attention so far. We outline the importance of a needs-oriented implementation in order to avoid negative outcomes such as a mere expansion of surveillance, an outsourcing of institutional responsibility, a loss of important social interactions and a deepening of the digital divide within the institution. In this paper, we further contend that the selective digital transformation of prisons can function as a ‘Potemkin façade’ enabling prisons to present themselves as modern without structurally improving the conditions of the majority of the prison population. These risks, which might be less obvious than security concerns, must be taken into account when evaluating and implementing digitalisation strategies.

Nano FeCoNi-based high-entropy alloy for microwave absorbing with high magnetic loss and corrosion resistance

With the development of modern communication and military technology, the protection of electromagnetic wave pollution and radar stealth technology have been widely concerned. In this background, the magnetic metals were widely used due to the strong ferromagnetism, which can induce strong magnetic loss to the electromagnetic wave. However, it remains challenging to precisely control the wave-absorbing performance of individual magnetic metals, and there are issues with poor corrosion resistance and high temperature resistance. Therefore, the alloy powders based on Fe, Co, and Ni in this work were prepared by wet chemical method at room temperature. Different from most of the traditional powder metallurgy methods, the wet chemical method enables us to obtain binary, ternary and quaternary alloys with a nanometer-scale and uniform distribution, all products have a microscopic morphology of 300–500 nm spheres. The FeCoNi alloy powder shows an effective absorption band (RL<-10 dB) of 7 GHz in the high frequency electromagnetic wave range at an ultrathin thickness of 1.5 mm, which has a high temperature magnetism (Tc >900 K) and excellent corrosion resistance. Further doping of Cu to form a quaternary alloy can improve the corrosion resistance and maintain the original wave-absorbing properties, while doping of Mo and Sn can adjust the position of the effective absorption bandwidth.
