The increasing number of Internet of Things (IoT) devices in different areas has led to worries about their susceptibility to security risks because of their limited resources. This study aims to improve IoT security by utilizing a streamlined key management system based on the PRESENT block cipher algorithm. The proposed method is compared to TinyIKE and Elliptic Curve Diffie-Hellman (ECDH) using key parameters like Encryption Time, Decryption Time, Storage Usage, Energy Consumption, and Key Entropy. The paper’s introduction contextualizes the importance of securing IoT devices, highlighting the difficulties caused by their restricted computational capabilities. The research proposes using the PRESENT algorithm for key management systems because of its lightweight characteristics and compatibility with resource-limited environments. The proposed method will be thoroughly analyzed across different parameters to evaluate its performance in comparison to current solutions. The research shows that the suggested lightweight key management scheme using PRESENT is more effective than TinyIKE and ECDH in Encryption Time, Decryption Time, Storage Usage, Energy Consumption, and Key Entropy. The results demonstrate the effectiveness of the suggested approach in meeting the particular security needs of IoT devices with limited resources. This research enhances IoT security by proposing a lightweight key management method that efficiently tackles the issues caused by resource-limited devices. The comparative analysis demonstrates that the proposed method outperforms others, indicating its potential as an effective solution for securing IoT ecosystems in practical scenarios.

Published: April 2024

An exhaustive examination and evaluation of hierarchy network security measuring and optimal active defense in the context of cloud computing is provided in this paper. After collecting all the cloud platform’s security-related data obtained via evaluation, the pertinent security data is summarized and analyzed to create the cloud platform’s safety record index. This index serves as a benchmark for the cloud platform administrators to evaluate the security vulnerabilities associated with their cloud platform. It offers cloud platform administrators a standard against which to assess the security hazards of cloud platforms. We primarily investigate the building of the cloud platform, the building process of the security situational awareness system, and the estimation of the safety circumstance value and use via the cloud platform’s security circumstance understanding system, thereby significantly enhancing the cloud platform’s stability, security, and dependability. By implementing the approach, the limitations of conventional network security management are circumvented, as the latter is predicated solely on historical data and is incapable of perceiving real-time alterations in the security condition of the system. Concurrently, the anticipated outcomes are incorporated into the imprecise decision-making system’s input, enhancing the evaluation’s precision. The approach improves the efficiency and efficacy of predicting the network safety situation in real time, augments the algorithm’s rate of convergence and prediction precision, and prevents overfitting from occurring. Simulation experiments conducted using the internet network safety posture dataset demonstrate that this research approach exhibits superior learning efficiency and lower prediction error compared to conventional machine learning and other deep learning techniques.

Published: April 2024

In the modern world, the development of the economy of any country is closely linked to the sustainable development of regions. Social processes play a crucial role in the sustainable development of a region. Much attention is paid to these processes in scientific works on economics, politics, sociology and interdisciplinary studies. We have touched upon the economic aspects of social development of regions. When writing the article such methods of scientific cognition as system approach, comparative and statistical analysis were used. The data on average monthly wages were used. Taking into account the presence of other sources of income, we also analysed the data on nominal cash incomes of the population by regions. In the analysis we used average per capita indicators to adjust for differences in the population size of the regions. The comparison was carried out using the unevenness index. The calculations revealed that the unevenness of both indicators is growing, which does not correspond to the current trends of sustainable development. The importance of the problem of sustainable development of regions in terms of social development is obvious, so we believe that the results of the research conducted in this article can be used for further scientific developments. Keywords: social development, sustainable growth, unevenness, regions, Kazakhstan, economy, wages, income, population, standard deviation.

Effects of Eccentric Speed during Front Squat Conditioning Activity on Post-activation Performance Enhancement of Hip and Thigh Muscles
Authors: Stastny Petr , Kolinger Dominik , Pisz Anna , Wilk Michal , Petruzela Jan , Krzysztofik Michal
Published: April 2024

The phenomenon of post-activation performance enhancement plays an unidentified role in movement eccentric speed and individual muscle group responses. Therefore, this study aimed to determine whether the loaded front squat (FSq) speed of the eccentric phase would influence the post-activation performance enhancement effect and whether the FSq would elicit similar performance enhancement of knee flexion, knee extension, hip flexion, and hip extension muscles. Twenty resistance-trained handball players performed the FSq under maximum eccentric-concentric speed and 2-s eccentric speed (only the eccentric phase performed), while pre- and post-front squat countermovement jump, knee, and hip isokinetic flexion/extension performance were tested. The FSq conditioning activity was performed in a single set of three repetitions with either 90% (maximum eccentric-concentric speed) or 120% (2-s eccentric speed) of one repetition maximum, and post-performance was measured 4–12 min after the FSq. Athletes randomly changed the FSq eccentric speed and tested the hip or knee isokinetic flexion/extension strength at 180°/s. ANOVA showed that the rate of force development during the jump increased (Cohen d = 0.59–0.77) with no differences between 2-s eccentric and maximum speed eccentric protocols. Isokinetic strength increased after the 2-s eccentric FSq in hip extension (d = 0.76–0.86), knee flexion (d = 0.74–0.88), and hip flexion (d = 0.82), with no differences in knee extension strength. After maximum eccentric-concentric speed, isokinetic strength increased in hip extension (d = 1.25). In conclusion, the FSq conditioning activity enhances hip extensors' performance more than knee extensors' performance. Different eccentric types of muscle action during a conditioning activity alter the level of local muscle enhancement.

Published: April 2024

The purpose of this study was to examine the differences in braking and propulsion force-time characteristics and barbell velocity between traditional (TRAD) and accentuated eccentric loaded (AEL) back squats using various load combinations. Sixteen resistance-trained men participated in four separate testing sessions which included a one repetition maximum (1RM) back squat during the first session and three squat testing sessions. During the squat testing sessions, participants either performed sets of three repetitions of TRAD back squats each with 50, 60, 70, and 80% 1RM or performed the same loads with the addition of weight releasers that increased the total eccentric weight of the first repetition of each set to either 100 (AEL-MAX) or 110% 1RM (AEL-SUPRA). Braking and propulsion mean force, duration, and impulse as well as mean and peak barbell velocity were compared between each condition and load. Significantly greater braking impulses were produced during the AEL-MAX and AEL-SUPRA conditions compared to TRAD (p < 0.03) with small-moderate effect sizes favoring AEL-SUPRA. No other significant differences existed among conditions for other braking, propulsion, or barbell velocity variables. AEL-MAX and AEL-SUPRA back squats may provide a greater braking stimulus compared to TRAD squats; however, the propulsion phase of the movement does not appear to be impacted. From a loading standpoint, larger and smaller load spreads may favor rapid and maximal force production characteristics, respectively. Further research on this topic is needed as a large portion of the braking stimulus experienced during AEL back squats may be influenced by relative strength.

Published: April 2024

We examined the effectiveness of two different jump-squat (JS) loading ranges on the physical performance of rugby players. Twenty-eight elite male rugby players were divided into two JS training groups: a light-load JS group (“LJS”; JS at 40% of the one-repetition maximum [1RM] in the half-squat (HS) exercise) and a heavy-load JS group (“HJS”; JS at 80% HS-1RM). Players completed the distinct training programs over four weeks, three times per week, during the initial phase of the competitive period. Pre- and post-training tests were conducted in the following sequence: vertical jumps, a 30-m speed test, peak power in the JS and the HS, and maximum isometric force in the HS. Additionally, the rating of perceived exertion (RPE) was assessed at the end of all training sessions throughout the intervention. A two-way ANOVA with repeated measures, followed by the Tukey’s post-hoc test, was employed to analyze differences between groups. The level of significance was set at p < 0.05. Effect sizes were used to assess the magnitude of differences between pre- and post-training data. Except for the RPE values (which were lower in the LJS group), no significant changes were detected for any other variable. In summary, using either a light- (40% HS-1RM) or a heavy-load (80% HS-1RM) JS during the initial phase of the competitive period is equally effective in maintaining physical performance levels attained during the preceding training period (pre-season), with the significant advantage of the light-load protocol resulting in lower levels of the RPE. This finding may have important implications for resistance training programming, especially in disciplines where acute and chronic fatigue is always a problematic issue.

Employee Attrition Prediction using Machine Learning Models: A Review Paper
Authors: Alqahtani Haya , Almagrabi Hana , Alharbi Amal
Published: April 2024

Employee attrition refers to the decrease in staff numbers within an organization due to various reasons. As it has a negative impact on long-term growth objectives and workplace productivity, firms have recognized it as a significant concern. To address this issue, organizations are increasingly turning to machine-learning approaches to forecast employee attrition rates. This topic has gained significant attention from researchers, especially in recent times. Several studies have applied various machinelearning methods to predict employee attrition, producing different resultsdepending on the employed methods, factors, and datasets. However, there has been no comprehensive comparative review of multiple studies applying machine-learning models to predict employee attrition to date. Therefore, this study aims to fill this gap by providing an overview of research conducted on applying machine learning to predict employee attrition from 2019 to February 2024. A literature review of relevant studies was conducted, summarized, and classified.

Research on Fuzzy C- Clustering Recursive Genetic Algorithm based on Cloud Computing Bayes Function
Authors: Xu Wang , Qiang Huang Wei
Published: April 2024

Aiming at the problems of poor local search ability and precocious convergence of fuzzy C-cluster recursive genetic algorithm (FOLD++), a new fuzzy C-cluster recursive genetic algorithm based on Bayesian function adaptation search (TS) was proposed by incorporating the idea of Bayesian function adaptation search into fuzzy C-cluster recursive genetic algorithm. The new algorithm combines the advantages of FOLD++ and TS. In the early stage of optimization, fuzzy C-cluster recursive genetic algorithm is used to get a good initial value, and the individual extreme value pbest is put into Bayesian function adaptation table. In the late stage of optimization, when the searching ability of fuzzy C-cluster recursive genetic is weakened, the short term memory function of Bayesian function adaptation table in Bayesian function adaptation search algorithm is utilized. Make it jump out of the local optimal solution, and allow bad solutions to be accepted during the search. The improved algorithm is applied to function optimization, and the simulation results show that the calculation accuracy and stability of the algorithm are improved, and the effectiveness of the improved algorithm is verified.

O artigo retrata um estudo cujo fito foi verificar o modo pelo qual professores de Educação Física escolar fomentam estratégias metacognitivas durante as aulas. Participaram da pesquisa: docentes e estudantes do 4º, 5º e 6º ano do ensino fundamental, de duas escolas da rede pública localizadas em um município do sul de Minas Gerais. Tratou-se de uma investigação orientada por métodos mistos resultantes das abordagens qualitativas e quantitativas. Em termos de recurso para coleta de dados, empregou-se o processo observacional de seis aulas de Educação Física ao longo de um mês letivo, somado a aplicabilidade de um questionário o qual visou cotejar informações sobre as estratégias metacognitivas direcionadas aos aprendizes. Os resultados sinalizaram que as referidas estratégias foram pouco promovidas no interior desse componente curricular. Malgrado, o professor e os estudantes da escola 1 (observada) apresentaram melhor eficácia e atuação, quando comparado aos discentes e professor da escola 2.  Conclui-se, portanto, que o incentivo às estratégias metacognitivas ocorre com baixa incidência e de forma intuitiva no contexto educativo cuja pesquisa foi desenvolvida.
