Exploring and Acquiring Modern Human Resource Competencies in Cybersecurity Amidst State Digital Transformation

This paper validates the relevance of contemporary electronic communication systems, networks, and hardware and software suites and tools being particularly susceptible to cyber influences. The goal of the article is to concisely summarize international experience in modern human resource competencies within the cybersecurity domain and to identify their components according to specific directions. The paper examines current international trends regarding the formation of a minimal necessary package for creating, implementing, technical support, and enhancing an information security and cyber defense management system. This necessitates the development of a digitally aware society by the state, a crucial area of its internal policy. It emphasizes the undeniable fact that the demand for cybersecurity professionals will continually grow as high-technology society advances. In the context of the state’s total defense, the role of unified training for defense force personnel and the civilian sector in cybersecurity is beyond doubt. It is concluded that the main focus in forming Cybercom of partner countries is adequate funding, careful selection of personnel, quality professional training, and ensuring full interoperability of diverse structural units of subjects ensuring information protection and cybersecurity at the state level. The share of cyber threats is increasing, and this trend will intensify over the next decade as the internet technology sphere is developing rapidly, and digital solutions are being used in combination (e.g., artificial intelligence and blockchain). For instance, current Russia is one of the main threats to national and international cybersecurity, actively implementing the concept of information confrontation based on a combination of destructive actions in cyberspace. An increase in conflicts between states and the intensity of intelligence and subversive activities in cyberspace is expected. The number of states seeking to form their own cyber-intelligence, master the latest methods of destructive influence in cyberspace, and strengthen state control over the state segment of the Internet is growing. The technical level of cyber threats is increasing, and new tools and mechanisms for cyber attacks are constantly being improved and developed

Large-Scale Fabrication of Tunable Sandwich-Structured Silver Nanowires and Aramid Nanofiber Films for Exceptional Electromagnetic Interference (EMI) Shielding.

The recent advancements in communication technology have facilitated the widespread deployment of electronic communication equipment globally, resulting in the pervasive presence of electromagnetic pollution. Consequently, there is an urgent necessity to develop a thin, lightweight, efficient, and durable electromagnetic interference (EMI) shielding material capable of withstanding severe environmental conditions. In this paper, we propose an innovative and scalable method for preparing EMI shielding films with a tunable sandwich structure. The film possesses a nylon mesh (NM) backbone, with AgNWs serving as the shielding coating and aramid nanofibers (ANFs) acting as the cladding layer. The prepared film was thin and flexible, with a thickness of only 0.13 mm. AgNWs can easily form a conductive network structure, and when the minimum addition amount was 0.2 mg/cm2, the EMI SE value reached 28.7 dB, effectively shielding 99.884% of electromagnetic waves and thereby meeting the commercial shielding requirement of 20 dB. With an increase in dosage up to 1.0 mg/cm2, the EMI SE value further improved to reach 50.6 dB. The NAAANF film demonstrated remarkable robustness in the face of complex usage environments as a result of the outstanding thermal, acid, and alkali resistance properties of aramid fibers. Such a thin, efficient, and environmentally resistant EMI shielding film provided new ideas for the broad EMI shielding market.

Application of Electronic Communication Signal Modulation Recognition System Based on Fourier Transform

Abstract In this paper, the weighted class fractional Fourier transform is redefined by means of the weighted superposition of state functions, and the Fourier transform is applied to dissect the intrinsic relationship between the M-WFRFT and the 4-WFRFT and to obtain the weighting coefficients of the electronic communication signals. On the basis of the WFRFT discrete algorithm, the electronic communication signal is expanded to include M a term after the M -WFRFT and the hybrid carrier modulation method based on the WFRFT is given. According to the design idea of the electronic communication system, the hardware part and software part of the electronic communication system are designed, and the electronic communication signal modulation recognition system is experimentally analyzed by using the simulation experiment method. The results show that when the signal-to-noise ratio is -8dB and the optimization algorithms are the Sgd algorithm, Sgdm algorithm, and Adam algorithm, the modulation identification accuracy of OFDM signal is 39.3%, 57.5% and 43.5%, respectively, which indicates that the Sgdm optimization algorithm is the most suitable one compared with other algorithms, and it is more effective in the modulation identification of OFDM signals at low signal-to-noise ratio. The number of scans of the three-layer multi-parameter WFRFT signal by the non-cooperative party is 6.4 × 1013 times, and the increase in the number of scans leads to an increase in the cost paid by the non-cooperative party, which confirms that the secure communication system based on three-layer weighted fractional-order Fourier transform has good resistance to parameter scanning characteristics and high confidentiality. This study further improves the a priori parameter setting of the electronic communication system and enhances its complexity, resulting in better anti-interception identification features.

Stable vortex waves generation by a flexible antenna made of highly conductive graphene film

Electromagnetic waves carrying orbital angular momentum (OAM and vortex waves) attract much attention due to their specific characteristics and prospects for use in wireless communication, biomedical engineering, and imaging. Vortex waves are complex spatial entities; therefore, their stable generation is a quite complicated task, especially in the radio frequency and terahertz wave domains, considering that the corresponding antennas must be precisely adjusted. Such adjusting is very difficult to achieve for flexible antennas, which are now being actively introduced into practice. Here, we propose a design of a flexible antenna that is able to stably generate waves carrying OAM even when being subjected to some bending. The antenna is composed of a ring-shaped resonator made of a highly conductive graphene film deposited on a thin polydimethylsiloxane substrate. The antenna is operated on two mutually orthogonal degenerate TMm1 modes excited by two supply strip lines to generate vortex waves with a desired topological charge. We verify this ability numerically and in a microwave experiment on two antenna prototypes deriving the OAM mode purity by changing the bending radius of the antenna bearing surface, giving it either positive or negative curvature. The obtained experimental results confirm that the antenna has good performance and can be used for flexible electronic devices and communication systems.

The Impact of Work-related Electronic Communication During Non-working Time on Work Performance

With the development of electronic information technology, the use of electronic communication equipment for work communication has become ubiquitous in people's work and life, and has brought a series of positive and negative effects. The purpose of this study is to review and analyze the academic literature on non-work time participation in work-related electronic communication. A significant finding is that most of the existing literature focuses on how non-working electronic communication affects employee initiative, work-family conflict, and time banditry behavior. At the same time, there is relatively little discussion on employee work performance. Therefore, this study aims to analyze the relationship between remote employees engaged in work-related electronic communication during non-working time and their work performance by applying affective events theory, job characteristics model theory, and job demands-resources model theory, to provide effective suggestions for enterprises and employees on how to balance work and life.

A Study on Communication Behaviour of Wheat Growers in Reasi Distt. of Jammu & Kashmir, India

Introduction of latest interactive communication technology among the rural population has opened a new vista of researchers to find out viability, acquaintance, accessibility, satisfaction, constraints and many more issues of the launched electronic communication technology and systems. There exists a gap between the information available and its dissemination. There is a need to find out better and faster means of communication which will bridge the gap between the researches and their applicability. The information technology revolution has provided huge opportunities to make easy access to information with interactive distance learning. The mechanism of internet and T.V. aided information technology help to reach the unreach.
 Wheat is an important crop grown in hilly Distt. Reasi of Union Territory of Jammu and Kashmir where different varieties of wheat are grown. Keeping in mind the importance of communication behaviour in the transfer of wheat production technology, a study on “Communication Behaviour of Wheat Growers in Reasidistt. Reasi of Jammu &Kashmir, India” was conducted in hilly District Reasi of Union Territory of Jammu and Kashmir which was selected purposively. Out of 12 C.D. Blocks 4C.D.Blocks namely Reasi, Pouni, Katra and Thuroo were selected randomly. A sample of 20 per cent villages was selected randomly from selected Gram Panchayats. A sample of 20 per cent Gram Panchayats from each selected block was selected randomly. A sample of 20 per cent villages from the selected Gram Panchayats was selected randomly. A sample of 20 per cent (150) wheat growers was selected randomly from selected villages. Hence, a total of 150 respondents were finally selected for recording their responses for study purpose. Communication behaviour of wheat growers has been operationalised as information input, information processing and information output behaviour of the respondents. An index was prepared for studying the communication behaviour of wheat growers, wherein information input was studied in terms of sources of information, processing of information was studied in terms of evaluation, storage and transfer of information and information output was studied in terms of dissemination of information.
 It was found that the majority of respondents were using Extension Personnel of KVK, Extension Personnel of Departments of Agriculture, progressive farmers, television, relatives and friends and radio as arranged rank wise 1, 2, 3,4, 5 and 6respectively as the main sources of information on wheat production technologies referred as the information input behaviour of the vegetables growers.
 A large number of farmers used to evaluate (processing) the information by discussing with the elder family members, progressive farmers, neighbourers and local leaders/key communicators as arranged rankwise 1, 2, 3 and 4 respectively. Majority of wheat growers stored the information by memorization and writing in general notebooks as arranged rankwise 1 and 2 respectively. A large number of wheat growers transformed the information by rearranging the important information as per their needs and rearranging the information in local dialect. Majority of wheat growers disseminated the information (information output) to their family members, neighbourers and those who cultivate in their lands as arranged rank wise 1, 2 and 3 respectively. It was found that majority of wheat growers had medium communication behaviour towards different wheat production information sources.

Timed Petri Nets for Modeling and Performance Evaluation of a Priority Queueing System

The application of queueing theory is very broad. Examples include electronic communication systems and devices. New technologies, electronic communication systems, and devices are used by many modern organizations. However, this implies certain requirements and risks. The requirements are, first and foremost, reliability, which accounts for the complexity and interdependence of the system. On the other hand, the stochastic characteristics and complexity of these systems introduce risks related to the demands of reliability control, transmission quality, availability, and security. The research conducted so far is concerned with relatively simple queueing models that require certain assumptions to be made about the stochastic nature of the event stream. This is because complex queueing systems are very difficult to analyze using analytical methods. Hence, this paper attempts to use timed Petri nets in the modeling and performance evaluation of queueing systems belonging to the PQS (Priority Queueing System) group. IntServ and DiffServ architectures are discussed, as well as queueing systems used in quality-of-service assurance. A weighted PQS that eliminates the possibility of blocking lower-priority traffic is investigated. Based on a Petri model, the performance characteristics of the studied system are obtained. The impact of data generation on the system performance was analyzed, showing that temporal Petri nets can be effectively used in the modeling and performance evaluation of PQS systems.

Incorporating Loss Factor Modular Design for Full Ku-Band Microwave Attenuation in Double-Layered Graphene Aerogels.

The fabrication of absorption-dominant electromagnetic interference (EMI) shielding materials is a pressing priority to prevent secondary electromagnetic pollution in miniaturized electronic devices and communication systems. Meeting this goal has remained a tough challenge to keep pace with the rapid evolution of electronics due to the complex compositional and structural design and narrow operating bands. This work articulates a sound and simple strategy to precisely modulate the electrical conductivity of reduced graphene oxide (rGO), as the building block in lightweight double-layered rGO-film/rGO-aerogel/polyvinyl-alcohol (PVA) composites, for efficient microwave absorption over the entire Ku-band frequency range. These constructs reasonably comprised a porous absorption structure built from parallel rGO sheets aligned and prepared via freeze casting followed by freeze drying. The electrical conductivity and impedance of this layer were tuned by varying the annealing temperature from 400 to 800 °C, thereby adjusting the degree of reduction and the absorption characteristic. This layer was backed by a highly conductive rGO film reduced at a high temperature of 1000 °C, with a reflectivity of 97.5%. The incorporation of this film ensured high EMI shielding effectiveness of the double-layered structure through the absorption-reflection-reabsorption mechanism, consistent with the predicted values based on calculated loss factors and the input impedance of the structure. Accordingly, at an average EMI shielding effectiveness of 57.59 dB, the reflection shielding effectiveness (SER) and reflectivity (R) of the assembled composites were optimized to be as low as 0.22 dB and 0.049, respectively. This equates to approximately 99.999% shielding (SET) and ∼95% absorptivity (A) of the incident wave. This study opens new avenues for the development of lightweight (with a density as low as 15 mg/cm3) absorption-dominant EMI shielding composite materials with promising EMI shielding efficiency and potential applications in modern electronics.

Evaluation of the Approaches Adopted by the Infectious Diseases and Clinical Microbiology Specialists and Medical Microbiology Specialists in the Case of Myroides spp. Growth in Urine Culture: A Survey Study

Myroides species are bacteria that, although rare, can cause a variety of serious infections, including urinary tract infections, and are often resistant to antibiotics. There are no studies on the knowledge and attitudes of specialists regarding Myroides spp. growth in culture in literature. In our study, the survey forms created with Google Forms (Google LLC, CA, USA) were shared in the e-mail groups of Infectious Diseases and Clinical Microbiology (IDCM) and Medical Microbiology (MM) specialties via electronic communication system. The results were evaluated statistically. 92 IDCM specialists and 75 MM specialists participated in the study. It was found that 48.9% of IDCM specialists and 20% of MM specialists have never seen Myroides spp. growth in a urine sample, and 32.6% of IDCM specialists and 14.9% of MM specialists still use the old name Flavobacterium for Myroides spp. (28.8% of MM specialists do not know that the name Flavobacterium is changed), and 45% of MM specialists who had previously seen Myroides spp. growth were able to recognize the Myroides spp. colony visually, and 53.3% of MM specialists who had previously seen Myroides spp. growth routinely performed antibiograms in case of Myroides spp. growth in urine culture, and 32.6% of IDCM specialists requested typing and sensitivity testing in case of Myroides spp. growth in urine culture, and 31.9% of IDCM specialists who had previously seen Myroides spp. growth considered Myroides spp. growth as a causative agent of infection in the presence of pyuria in urine, while 36.2% always considered it as colonization/contamination, and 61.7% of IDCM specialists only changed the catheter without giving antibiotics when they considered Myroides spp. as a causative agent of infection, while 21.3% gave antibiotics according to the antibiogram result. As a conclusion; our study is the first study in the world to investigate the knowledge and attitudes of infectious disease specialists and medical microbiologists about Myroides spp. growth in urine culture. The findings of our study showed particularly that approximately half of the IDCM specialists had not seen Myroides spp. growth in urine culture and that some of the specialists may have a low level of knowledge about Myroides spp.. Additionally, among the specialists participating in the study, it was shown that attitudes and approaches in the case of Myroides spp. growth in urine were not directly related to the hospital that they worked and their years of experience in specialty. Our findings suggest that MM and IDCM specialists need an update of their knowledge on Myroides spp.

Flow of information contributing to medication incidents in home care-An analysis considering incident reporters' perspectives.

To describe the contributing factors and types of reported medication incidents in home care related to the flow of information in different phases of the medication process, as reported by multi-professional healthcare groups. This descriptive, qualitative study used retrospective data. An incident-reporting database was used to collect 14,289 incident reports from 2017 to 2019 in a city in Finland. We used this data to select medication incidents (n = 1027) related to the flow of information in home care and between home care and hospitals. Data were divided into five groups based on the medication phase: (1) prescribing, (2) dispensing, (3) administration, (4) documentation and (5) self-administration. In addition, the types of medication-related incidents were described. The data were examined using abductive content analysis. The EQUATOR SRQR checklist was used in this report. Four main categories were identified from the data: (1) issues related to information management, (2) cooperation issues between different actors, (3) work environment and lack of resources and (4) factors related to healthcare workers. Cooperation issues contributed to medication-related incidents during each phase. Incomplete communication was a contributing factor to medication incidents. This occurred between home care, remote care, hospital, the client and the client's relatives. Specifically, a lack of information-sharing occurred in repatriation situations, where care transitioned between different healthcare professionals. Healthcare professionals, organisations, clients and their relatives should focus on the efficient and safe acquisition of medications. Specifically, the use of electronic communication systems, together with oral reports and checklists for discharge situations, and timely cooperation with pharmacists should be developed to manage information flows. These findings demonstrate that healthcare professionals require uniform models and strategies to accurately and safely prescribe, dispense and administer medications in home care settings. No patient or public contributions.

Semi-Blind watermarking using convolutional attention-based turtle shell matrix for tamper detection and recovery of medical images

“Telemedicine or e-medicine” refers to an electronic communication system that shares medical information from one location to another through the transmission channel. The increase in multimedia data sharing/transmission across the communication channel has raised to an uncontrollable stage. Thus, the transmission of medical reports across the network has increased higher, which has a chance of tampering either intentional or unintentional attacks. In the case of deliberate attacks, tamper detection and localization are the highly required criteria to verify the originality. In such cases, medical image authentication, security, and integrity verification are also essential criteria in telemedicine applications to verify whether the report belongs to the right person or not. To achieve these criteria and to satisfy these requirements Digital watermarking techniques are highly suggested. Much research has been carried out to address this issue, but some drawbacks and limitations still need to be addressed. The objective is to accomplish a Tamper detection, localization, and recovery (TDLR) system with minimal source information at the receiver end with a better payload or embedding capacity. This paper presents a novel Conventional Attention network (CoAtNet) based invariant watermark generation. A two-level embedding is proposed to enhance watermark security, where image tamper localization and recovery information is generated. The primary level of embedding is carried out by the Turtle Shell Data Hiding Algorithm (TSDH), and the secondary level of embedding is carried out by the DWT-SVD transform. The result shows that the proposed model achieves high imperceptibility and tamper detection accuracy of 60.24 and 99.51% respectively. Furthermore, the suggested system performed well in evaluations of tamper detection and image restoration for various malicious attacks against state-of-the-art systems.

A Review on the Design of Equalizers for Frequency Selective Channels

Wireless channels rarely fulfill the conditions required for distortion-less transmission. sensible wireless channels suffer from the impact of a non-flat magnitude response and a non-linear section response that leads for distortions within the received signals. what is more effects liketiny scale weakening, massive scale weakening and physicist shifts cause dis- similarity between the transmitted and received signals. Wireless channels not showing the perfect impulse response ends up in the reception of multiple copies of the transmitted signal at the receiver thereby leading to entomb image Interference (ISI). A additive and cascading impact of the on top of mentioned reasons ends up inthe degraded performance of electronic communication systems. to avoid these prejudicial effects, many equalizer styles are projected.This paper focuses on the design aspects of equalizers with an inclination towards decision feedback equalizers, due to their efficiency in nullifying the detrimental effects of practical wireless channels. Keywords: Frequency Selective Channel, Equalizer, Decision Feedback Equalizer, Bit Error Rate (BER), Probability of Error (Pe), Throughput.

Designs of Array Multipliers with an Optimized Delay in Quantum-Dot Cellular Automata

Quantum-dot cellular automata (QCA) has been considered as a novel nano-electronic technology. With the advantages of low power consumption, high speed, and high integration, QCA has been treated as the potential replacement technology of the CMOS (complementary metal oxide semiconductor) which is currently used in the industry. This paper presents a QCA-based array multiplier with an optimized delay. This type of circuit is the basic building block of many arithmetic logic units and electronic communication systems. Compared to the existing array multipliers, the proposed multipliers have the smallest cell count and area. The proposed designs used a compact clock scheme to reduce the carry delay of the signals. The 2 × 2 array multiplier clock delay was reduced by almost 65% compared to the existing designs. Moreover, since the multiplier exhibits a good scalability, for further proof, we proposed a 3 × 3 array multiplier. Simulation results asserted the feasibility of the proposed multipliers. Extensive comparison results demonstrated that when the design scaling was increased, our proposed designs still displayed an efficient overhead in terms of the delay, cell count, and area. The QCADesigner tool was employed to validate the proposed array multipliers. The QCADesigner-E was used to measure the power dissipation of the alternative compared solutions.

Preliminary Development of an upgrade of a chamber to measure the response of quartz crystal resonators

Quartz crystal microbalance (QCM) sensors have been frequently used as weighing devices, since they have proven to be sensitive due to shifts in their resonant frequency due to increments in the mass attached to their surface. These, are normally used as sensor arrays for systems known as "Electronic Noses", to detect and analyze gases, fluids, medical and environmental applications, and biological compounds, among others. For the implementation of such systems, it is necessary to characterize the response of the sensors at different types of compounds, primarily in temperature-controlled environments, which implies the use of control systems with a high cost. This work presents the preliminary design of a static system to measure the response of quartz crystal gas sensors, as a lower cost proposal, using an open-loop controlled temperature environment, through an electronic communication system with the computer and a virtual instrumentation software to monitoring and manipulating the temperature. To observe the effectiveness of the system, real QCM gas sensors with a coat of sensing film of ethyl cellulose were used, applying concentrations of ethanol. In addition, temperatures of 25°C, 35°C and 45°C were adjusted, obtaining typical results of the response of this type of sensors.

Synthesis, Characterization, and Electromagnetic Properties of Ba1.8Sr0.2Co2Fe11.9Pr0.1O22/Ti3C2Tx‐MXene Composites

Ba1.8Sr0.2Co2Fe11.9Pr0.1O22/Ti3C2Tx‐MXene composites are synthesized with the unique combination of magnetic and conducting components that enhance electromagnetic wave absorption. Ba1.8Sr0.2Co2Fe11.9Pr0.1O22, Ti3C2Tx‐MXene and their composites in a weight ratio of 100:0 (YM1), 75:25 (YM2) and 50:50 (YM3) are synthesized by sol–gel autocombustion, etching process, and mechanical blending, respectively. From the morphology of the composites, Ba1.8Sr0.2Co2Fe11.9Pr0.1O22 particles are confirmed to be well‐integrated with the Ti3C2Tx‐MXene, indicating that the Ba1.8Sr0.2Co2Fe11.9Pr0.1O22 particles are evenly distributed in the Ti3C2Tx‐MXene, leading to homogeneous composites. M–H loop exhibits a saturation magnetization and coercivity of 23.01 emu g−1, 14.87 emu g−1, 12.45 emu g−1, and 87.44 Oe, 94.06 Oe, 102.97 Oe for YM1, YM2, and YM3, respectively. The reflection losses for YM1, YM2, and YM3 are −8.88, −11.64, and −21.39 dB, respectively. The double‐resonance peaks contribute to two magnetic loss peaks in YM3 within a broad frequency range. The higher attenuation constant is observed for YM3 corresponding to a stronger electromagnetic absorption. The improved electromagnetic properties of the composites can be attributed to the synergistic effect between the Ba1.8Sr0.2Co2Fe11.9Pr0.1O22 and Ti3C2Tx‐MXene, which enhances the impedance matching and increases the absorption of electromagnetic waves. These improved electromagnetic properties are important in applications such as electronic devices and communication systems.

The Effects of Digitalization as Challenges to the Effectiveness of Democracy and “Mass Policy” at the Present Stage

The article is devoted to the problem of the influence of the effects of digitalization on institutions and ideology of democracy in its various modern interpretations, as well as on the very evolution of the formats of participation of the masses in politics. Technological progress and the development of electronic communication systems lead to often unexpected, if not paradoxical, consequences in the relationship between elitism and mass politics. As a result, a new stage in the struggle for the management of public opinion and the main channels of communication is at the same time a consequence of technological changes and the evolution of the “mass” policy’s previously unregulated basic contradictions. The elitist approach is characterized by a priority course of maintaining control over the key digital platforms “for the common good” through agreements with the “digital oligarchy”, which minimizes destructive, from the point of view of the political mainstream, attempts by counter-systemic forces to change the status quo in dominant ideologies, values and power relations. For the extension adepts of mass politics, the new technical possibilities just give a hypothetical chance to correct the status quo, and in this sense, the “progressive” agenda opens the way for the conservative, and for outsider, in relation to the political mainstream, political and intellectual groups.
