Na atualidade, diversas atividades foram e ainda são transformadas de forma que facilite seus processos. Essa facilitação tem como consequência uma diminuição do movimento humano, o qual tem papéis relacionados à saúde, mobilidade, motivação e socialização, além de aumentar o índice de sedentarismo. O sedentarismo é uma situação em que a pessoa não pratica um nível mínimo de atividade física diariamente, e o mesmo pode interferir na qualidade de vida das crianças e adolescentes. O objetivo desse estudo foi comparar a qualidade de vida de acordo com o nível de atividade física em escolares do município de Caxias do Sul - RS. Trata-se de um estudo transversal com amostragem não probabilística por acessibilidade, composta por escolares de sete a nove anos da rede municipal de Caxias do Sul/RS no ano de 2018. O nível de atividade física foi avaliado pelo Physical Activity Questionnaire for Children (PAQ-C) e a qualidade de vida pelo KINDL QV- Genérico. Um teste T- independente foi utilizado para comparação entre os grupos, com um nível de significância de p≤0,05. Dos 720 escolares entrevistados, apenas 18,1% (n=130) foram classificados como ativos, restando um total de 81,9% (n=590) classificados como sedentários. Em relação à qualidade de vida, o escore geral foi de 76,8±9,8 pontos, demonstrando um bom nível de qualidade de vida. Comparando os grupos, percebemos que os escolares sedentários apresentaram menores escores nos domínios autoestima (p=0,007), amigos (p=0,002) e no escore total (p=0,002). Para os demais domínios não foram observadas diferenças significativas entre ativos e sedentários (p≥0,05). O presente estudo pode concluir que a maior parte dos escolares avaliados foram classificados como sedentários e estes apresentaram pior escore na qualidade de vida geral e nos domínios autoestima e relação com amigos.

Authors: Rumiantseva A.
Published: September 2024

The relevance of the article conditioned by the modern immediacy of the problem of maintenance of spiritual values, by the necessity of the research of regional features of composer’s schools and specifics of embodiment of spiritual instructions in V. Ptushkin’s compositional, particularly piano creativity, that hasn’t got an exhaustive coverage in modern national musicology.
The purpose of the article is to highlight the specifics of the concept of spirituality as the worldview and axiological center of V. Ptushkin’s compositional, particularly piano creativity.
The methodology of the article is based on comparative, historical-typological, interpretative method, methods of generalization, stylistic and genre analysis.
The results. The article highlights the concept of spirituality, represented as a concentrated reflection of the humanistic orientation of V. Ptushkin’s compositional, particularly piano creativity and a means of affirming spiritual values in a dialogue with the spiritual experience of mankind, appeals to the signs of cultural eras, genre model of the past — requiem, choral, spiritual cantata, concerto grosso, in the reproduction of eternally relevant images and themes — symbols of spirituality, in particular the image of Virgin Mary as the ideal of humanity’s existence and the positioning of the sublime and the earthly as the poles of worldview and human existence. It is revealed that the specificity of the embodiment of the concept of spirituality in the work for two pianos “The Sublime and the Earthly” is related to: understanding its significance through the prism of comparing personal and universal principles and allusions to the signs of the Renaissance, Classicism, romanticism; resonance with worldview guidelines of the culture of the border of XX–XXI centuries; functional mobility; the variability of performing teams; compositional and structural abnormality. The global significance of the concept of spirituality is imprinted in the work on the following levels: texture — in large-scale vertical chords, chronotope and dynamics — in powerful orchestral sonority, tonal organization — in the affirmation of major constructions, genre — in the movement from lyrical, individualized elegy to anthem as a reflection of the human unity.
The scientific novelty of the article is due to the substantiation of the concept of spirituality as a worldview basis of V. Ptushkin’s work and the study of the peculiarities of its embodiment, in particular in the play «The Sublime and the Earthly».
The practical significance of the article is determined by the possibility of using the results of the study in performing and pedagogical practice.

Energy­efficient routing protocol in wireless sensor networks
Authors:   State University of Information and Communication Technologies, Kyiv, Dakova L. V.
Published: September 2024

Recently, self-organizing networks have gained popularity, which are distinguished by the possibility of connecting terminals anywhere and at any time without the need for a centralized network infrastructure. Mobile self-organizing networks are a promising direction for the development of information and communication systems. However, one should take into account the problems arising from the very nature of such networks: mobile nodes lead to an increase in the dynamism of the network topology due to the possibility of disconnection and the probability of movement; the limited supply of power sources of nodes requires careful management of power consumption in the design of hardware and protocols. Energy-saving design in self-organizing networks is more complex and important than in other wireless networks. The lack of infrastructure requires mobile nodes to act as routers, which increases traffic and therefore power consumption. Also, the energy-saving mode must take into account different network performance criteria, which can be caused by different protocols and power limitations. Thanks to the latest advances in technology and the rapid development of the production of small and affordable sensors, it has become possible to use them technically and economically effectively. These electronic sensors, which have high sensitivity, measure environmental parameters and convert the received data into an electronic signal that is transmitted over a wireless channel. After processing this signal, you can get information about the properties of objects or events that occur near the sensor. The application of a large number of such sensors, which can monitor a large area and exchange data wirelessly, forms a single wireless sensor network. Route allocation is a key challenge for resource-constrained networks. With the growth of computing power in wireless sensor technology, these sensor nodes are required to be equipped with more and more capabilities to perform more complex tasks. Each sensor is limited by its energy level, processing power, and ability to perceive information. Thus, the network of these sensors forms a more reliable and accurate structure. The article discusses the issue of using the HABRP protocol for its application in wireless sensor networks. The use of the HABRP protocol allows for improvement in the efficiency of wireless sensor networks, namely their energy efficiency. Therefore, the energy efficiency and simplicity of the HABRP protocol make it an excellent candidate for use in wireless sensor networks.
Method of operating assessment of the state of network elements to ensure the quality of services in corporate high­speed multiservice communication networks
Authors:   State University of Information and Communication Technologies, Kyiv, Drobyk O. V.
Published: September 2024

The article proposes intelligent methods and algorithms for operational assessment of the state of network elements to ensure indicators of the quality of communication services in corporate multi-service communication networks that function in a mode close to real time. A feature of corporate multi-service networks is the high dynamics of changes in their state. And the task of the automated network management system is to ensure the given quality of communication services. Thus, the relevance of this study is determined by the need to implement network management processes in a mode close to real time, with a given quality. The basis of the method of operational assessment of the state of network elements is the concept of using intelligent agents. In the proposed approach, intelligent agents are created as hierarchical fuzzy situational networks, in which management decisions, in contrast to known methods based on the application of reference situations, are produced on the basis of solving a hierarchical system of optimization tasks based on fuzzy mathematical programming methods. The main paradigm of their functioning is «situation – action». This makes it possible to significantly reduce the dimension of the task to be solved and obtain Pareto-optimal solutions for managing the quality of communication services. The intelligent agent of management solutions can be implemented automatically, provided that the network administrator delegates such capabilities to it. The method of estimating traffic parameters is based on the concept of conditional nonlinear Pareto-optimal filtering. Its essence is to apply a two-stage procedure; at the first stage, a forecast of the values of parameter estimates is made, but in the second, with the receipt of the following observations, their values are adjusted. The average relative error of traffic parameter estimation does not exceed 10%, which is sufficiently operational for managing the quality of communication services.
Zero trust architecture logical components and implementation approaches
Authors:   State University of Information and Communication Technologies, Kyiv, Prydybaylo O. B.
Published: September 2024

Zero Trust Architecture (ZTA) is a contemporary cybersecurity approach that challenges the traditional perimeter-based security model. In the zero-trust model, organizations do not automatically trust any user or device, regardless of whether they are inside or outside the corporate network. Instead, it assumes that threats can come from both internal and external sources, and it verifies every user and device attempting to access resources. Here are the key principles of this software development trend: • Identity verification: individuals need to authenticate their identity before gaining access to resources. This often includes multifactor authentication and reliable verification methods. • Least privilege access: users are granted the minimum access required to perform their tasks. Access is limited only to essential elements, reducing the potential impact of a security breach. • Micro-segmentation: involves segmenting the network at a granular level, allowing isolation and protection of individual resources. • Data encryption: encryption is applied both during transmission and at rest to safeguard data from unauthorized access. • No implicit trust: applying the principle of "never trust, always verify," meaning verification is necessary at every stage of access. The article discusses modern challenges and approaches to cybersecurity amidst the rapid development of cloud technologies. Specifically, it analyzes the shift in container usage in software deployment and its impact on the cybersecurity model. Security approaches based on the concept of Zero Trust Architecture (ZTA) are highlighted in the context of new demands and opportunities. The article elaborates on key logical components of ZTA, such as policy mechanism and policy administrator, pointing out their interaction in creating a secure environment. It also provides an overview of data sources used for creating access policy rules and their consideration in ZTA mechanisms. Additionally, approaches to implementing ZTA for operational workflows in corporate environments are proposed: enhanced identity management, logical micro-segmentation, and network-based segmentation. Each of these approaches has its advantages and is considered based on the needs of individual organizations.

Authors:   State University of Information and Communication Technologies, Kyiv, Kaznacheyeva A. V.
Published: September 2024

The advancement of solar technology has facilitated the development of autonomous power stations that primarily rely on solar energy. This article delves into the crucial role that smart cleaning technologies play in enhancing the efficiency of these solar power modules. Solar panels, pivotal in harnessing solar energy, require regular and effective cleaning to maintain their efficiency. Traditional cleaning methods, although somewhat effective, are increasingly becoming insufficient due to the evolving demands of autonomous systems. The focus of this research is on the innovative integration of the Internet of Things (IoT) technologies to optimize the cleaning process. IoT not only enables remote monitoring and control but also automates the cleaning process through advanced algorithms that assess environmental data and panel conditions. This optimization ensures that the panels operate at peak efficiency by scheduling cleaning sessions based on actual needs rather than fixed intervals. Specifically, the study explores various smart devices such as autonomous robots and drones equipped with sensors and cleaning systems. These devices perform tasks ranging from dust detection to thorough cleaning without manual intervention, significantly reducing the labor cost and time involved in maintaining large solar farms. The use of embedded sensors and cameras facilitates real-time monitoring of the panels’ conditions, detecting any inefficiencies or malfunctions early. Furthermore, this article highlights the potential of mobile applications in smart cleaning systems. These applications provide operators with real-time data analysis, system status updates, and the flexibility to adjust operational parameters remotely. This capability not only enhances the responsiveness of the maintenance teams but also contributes to a proactive maintenance culture, preventing potential downtimes. In conclusion, smart cleaning technologies, powered by IoT and supported by innovative hardware and software solutions, represent a significant advancement in the field of renewable energy. They ensure that solar power modules operate at their highest potential, thereby supporting the broader goal of sustainable and efficient energy use in autonomous power stations. This research underscores the transformative impact of integrating smart technologies in the renewable energy sector, suggesting that continued innovation in this area is essential for the future of sustainable energy infrastructure.
Algorithms for detecting the structure of labyrinths and studying the efficiency of their application
Authors:   State University of Information and Communication Technologies, Kyiv, Іlyin O. O.
Published: September 2024

The article considers labyrinths in the context of the task of their creation and completion for use in the gaming IT industry. Artificial intelligence is currently used to simulate human behavior in computer games, which, depending on the algorithms, more or less imitates the intelligent behavior of a computer opponent. The peculiarity of a computer player is that at the software level, computer opponents have access to all objects of the game situation: the level map, the game board, etc. For a better human imitation of the behavior of the agent, the data coming to it is suppressed in such a way that it coincides with the data that a person in the same situation can receive using the senses. Therefore, it is important to apply appropriate algorithms for finding a way out of it, as well as recognizing their structure. The study of path-finding algorithms and the structure of the labyrinth for the detection of "human-like" approaches, and the evaluation of the effectiveness of such algorithms, allows us to identify better algorithms on the basis of which it is possible to develop games with a more interesting plot. Thus, this work is devoted to the research of algorithms for finding the structure of a labyrinth. Achieving the final goal involves the practical development of software in the Java language for visualizing their structure and obtaining specific values of the performance parameters of the selected algorithms. The work provides basic information about labyrinths, their main varieties and structures, and provides a mathematical model of an ideal labyrinth. Questions related to the selection of parameters for evaluating the effectiveness of their work, the direct analysis of algorithms, the design of a test application in Java and the analysis of the obtained results are investigated and resolved. During the performance evaluation, several structure research algorithms were analyzed in terms of speed of operation, and recommendations were given to choose the most optimal of the ones presented.
Methods of ensuring the invariance of parameters in infocommunication networks in emergency situations to forecasting and random disturbances
Authors:   State University of Information and Communication Technologies, Kyiv, Berkman L. N.
Published: September 2024

Currently, the mode of operation of information and communication networks corresponds to the emergency mode. In this mode, it is necessary to ensure the invariance (insensitivity) of network parameters under random disturbances that actually act on the signal as various interferences. Thus, the main task of the information and communication network is to ensure that the deviation of the parameters from the norm is within acceptable limits. This quality of invariance of the information and communication network must be ensured both for predictable disturbances and unpredictable random facts. Ensuring the invariance of information transmission systems is characterized by such a parameter as noise immunity. The quantitative assessment of noise immunity is the probability of error. The task of ensuring invariance is to preserve the quantitative characterization of the error probability. It is necessary that the error probability be less than the specified one and remain unchanged despite the presence of interference that causes the information transmission system to be unstable in emergency situations. Thus, a given quality of the system’s functioning is achieved due to the invariance of the error probability, its independence from predictable and random unpredictable disturbances. That is, the system will have the properties of invariance. The article presents methods for achieving invariance. Examples are given to illustrate the basic concepts of the theory of invariance and practical methods for building information transmission systems invariant to various interferences in emergency situations.

Authors: Al-Zamili Hussein Ali Awadh , Al-Mayaly Ithar Kamil
Published: September 2024

Linear alkylbenzene sulphonate (LAS), a surfactant frequently incorporated into detergent formulations, typically ends up in wastewater treatment facilities after use. The present study aims to investigate the efficacy of bacteria isolated from Iraqi wastewater in removing LAS. This strain was identified as Pseudomonas aeruginosa by genetic analysis (16S rRNA). Three LAS concentrations (25, 50, and 100 mg/l) were employed in this investigation, along with three temperatures (30, 35, and 40 oC) and pH values (5, 7, 9). The LAS anionic surfactant demonstrated optimal biodegradation by Pseudomonas aeruginosa at a temperature of 30 °C and at pH levels of 7 and 9, with removal percentages of 93.76% and 90.4%, respectively, at a concentration of 25 mg/l of LAS. The study's findings demonstrated the possibility and importance of using aerobic biodegradation to remove LAS from actual effluents. This bacterium is useful for bioremediation because of its capacity to break down LAS.
Prediction of shear wave velocity in three sedimentary rocks in East Baghdad oilfield using multiple regression analysis
Authors: Jawad Ali K. , Hadi Farqad A.
Published: September 2024

Shear wave is a crucial parameter for assessing the wellbore stability, the stress response, and rock deformation. It is essential for constructing the mechanical earth model (MEM) for many applications related to reservoir geomechanics including wellbore stability, sand production, hydraulic fracturing, and fault reactivation. However, shear sonic data is often omitted during the well-logging measurements for cost and saving purposes. To overcome this challenge, recent research has been focused on determining shear wave velocity through the use of core plugs, empirical correlations, artificial intelligence techniques, and multiple regression to quantify and evaluate the mechanical properties of subsurface formations without performing direct measurements at the wellbore. The greatest difference between this study and the literature is to predict the shear wave velocities for three sedimentary rocks based on conventional well logs.
   This study has been conducted on datasets of two wells drilled in the East Baghdad oilfield, for which there is a lack of shear wave data. Two formations (Tanuma and Zubair formations) within the production section of this field were conducted to develop new models for determining the shear wave velocity using multiple regression analysis. These two formations primarily consist of three lithologies: limestone, sandstone, and shale. Before the model development, data analysis on the selected data was applied to figure the most influential parameter(s) in determining the shear wave velocity. The results of the developed models are then compared with the previous models in the literature.
   The results showed that the multiple regression analysis technique is a powerful technique in determining shear wave velocity with high-performance capacity. The correlation coefficient ( ) and the root mean square error (RMSE) were 0.84 and 0.092 for limestone, 0.84 and 0.0972 for sandstone, and 0.86 and 0.0796 for shale respectively. Furthermore, the performance of the developed models is well matched to the actual shear wave data rather than the Castagna correlations. The findings of this study are effective in determining shear wave velocity for future applications related to reservoir geomechanics without needing costly well-log or core measurements.
Design, synthesis, and evaluation of some metal ion complexes of mannich base derived from 2-Mercaptobenzimidazole as potential antimicrobial agents
Authors: Sabah Thuraya Q. , R. Baqer Shaymaa
Published: September 2024

This study aims to prepare new compounds and investigate them spectroscopically and biologically against selected types of positive and negative bacteria and fungi to demonstrate their biological effectiveness. The prepared ligand combining formaldehyde, indole, sulfa benzamide, and 2-mercapto benzimidazole, a Mannich base ligand (L) was synthesized. The six metal ions including Cobalt (II), Nickel (II), Copper (II), Palladium (II), Platinum (IV), and gold (III) have interacted with the ligand and formed new complexes. Different spectroscopic methods, including C.H.N.S., FTIR, UV- Range visible, 1HNMR, 13CNMR, mass spectra, magnetic moment, and molar conductivity were used to suggest the new geometry of the complexes. The result from the infrared spectrum showed that the ligand behaves as tridentate with all prepared complexes. Conductivity analysis revealed the electrolytic nature of palladium, platinum, and gold ions complexes and non-electrolytes. The antibacterial activity of the compounds that were produced was tested using an agar-well diffusion procedure towards two strains of gram-positive as well as two strains of gram-negative bacteria and fungi (Staphylococcus, Streptococcus, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans) respectively at 0.02M. The standard (∆Eo) and (∆Hfo) of ligand and six complexes were calculated using the program Hyper chem 8.0.7. The research established that complexes are more stable than ligands. Calculated HOMO and LUMO and vibration frequencies using (parametric method 3 (PM3)) to find out the active sites in the ligand showed that they can coordinate and note the extent to which the results of theoretical vibrational frequencies are close to the process when calculating the vibrational frequency of the active aggregates.

Published: September 2024

A successful synthesis of mesoporous Santa Barbara amorphous (SBA-15) with nanoparticle size was attempted using prepared sodium silicate from Iraqi high silica sand. EO20PO70EO20 copolymer was used as a template at highly acidic conditions (pH < 2). The effect of crystallization temperature of (100, 110, 120, and 130 0C), and crystallization time of (24, 48, 72, and 120 h) on surface properties was studied. The experiments were characterized using XRD, FTIR, AFM, BET, and FESEM. The XRD and FTIR tests represent amorphous SBA-15 without any impurities. Decreasing average particle size distribution increased the surface area, and decreased the porosity (pore volume, and pore size) in all experiments. The texture properties were surface area of 210-756 cm2/g, volume pore of 0.28-0.7 cm3/g, and pore size of 1.94-13.45 nm. The optimum result of surface area was achieved at hydrothermal conditions of 110 0C, and 24 h, while optimum results of pore volume, and pore size were achieved at hydrothermal conditions of 100 0C, and 120 h.  Semi-spherical shape of particles appeared at hydrothermal conditions of 120 0C and 24 h. This morphology was transferred to small rods at 130 0C, and to semi-platelets at 120 h.

Authors: Hammood Noor M. , Abdulrazzaq Nada N. , Akrouti Inen
Published: September 2024

In this study, lead ions were removed from simulated wastewater by batch adsorptive filtration. A three-dimensional printed water filtration was designed using a blender and successfully synthesized from a PLA spool and a 3d printer machine. The filter surface was treated with NaOH solution to hydrolyze the polyester group in PLA. After that, α-Fe2O3 was prepared by the coprecipitation method and coated on the filter through doping and drying. α-Fe2O3 was characterized by X-ray diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDX), and Brunauer-Emmet-teller (BET). The results successfully indicate the synthesis of α-Fe2O3 consisting of 67.3% Fe and 32.7% O2. α-Fe2O3 appeared to have a surface area of 95 m²/g with distinct morphology and functional group. The effect of initial Pb concentration (100-800) ppm and the effect of contact time (5-120) min on the removal process were studied. Lab data was collected, and the adsorption was investigated kinetically. The 3d printed filter system coated by iron oxide showed significant and promised results for wastewater treatment and lead ions removal using this technique. Also, the results showed that the adsorption of Pb ions on the α-Fe2O3 surface fitted with the Langmuir model, with a correlation coefficient (R²) of 98.65%.  The kinetic model’s investigations revealed that the pseudo-second-order model was the most fitted model for the process with R² of 99.997%. The highest adsorption saturation capacity was 165.2 mg/g adsorbent.
Analytical and descriptive study of the production behavior for pilot multi-stages hydraulic fracturing wells in southeast Iraq
Authors: Hashim Ameer H. , Al-Jawad Mohammed S.
Published: September 2024

The hydraulic fracturing technique is a widely used technique worldwide, making it interesting to study. This technique was applied for the first time in Iraq on a tight carbonate reservoir in the Halfaya oil field. In this field, the oil production rates, and flowing pressure were low during production periods reflecting a problem for the development plan designed to increase production using a hydraulic fracture technique.  Initially, the hydraulic fracture well showed high oil-producing rates, but then, quickly experienced a high decline failing to keep a stable production rate. To address this problem, it is important to describe and analyze the behavior of pilot hydraulic fracturing wells during their production period, study the inflow performance relationship (IPR), and determine the optimum wellhead pressure above the bubble point pressure (Pb) to avoid loss of lifting energy. Furthermore, it identifies the allowable flow rate to keep stable production, investigates the effect of selecting internal tubing size, and reveals a future production procedure for hydraulic fracture wells.
   This study reveals that the transient inflow performance relationship observed in the production history of hydraulic fracture well in the tight carbonate reservoir and traditional inflow performance relationship concepts are not applicable. The optimum wellhead pressure for stability in production for Wells w-5 and w-55 is determined to be 750 and 580 psi with optimum rates of 800 and 450 Bbl/D, respectively. The results also showed that producing at a high flow rate may cause a depletion in the fracture potential storage without giving an opportunity for a reservoir to compensate for the produced fluid into fracturing potential storage. The internal tubing size has a passive effect on the hydraulic fracture well, as an increase in size causes an unstable flow zone. Lastly, future production procedures emphasize keeping wellhead pressures stable or increasing them if they drop. This can be accomplished by re-adjusting the choke size according to any changes observed.

Published: September 2024

The judiciary played a significant role in the evolution of democracy in Pakistan. Throughout history, the military remained at the core of politics and as an avoidable stakeholder influenced the judiciary in validating its extraconstitutional actions. However, after 2009, the judiciary emerged as exceptionally independent invalidating extraconstitutional actions and stretching its authority to take up matters else within the jurisdictional province of the other state organs, resulting in judicial overstretch. Excessive judicial activism had evident adverse impacts on the equilibrium of the state organs, imposed financial liabilities, and compromised its dignity. By employing qualitative research methodology, this article considers the judiciary as a double-edged weapon and critically examines the cases where the judiciary deviated from the international treaty obligations, leaving the fragile economy of Pakistan to a blow of penalties. Lastly, the research contributes to what Pakistan can learn from the US Constitutional construct.

Regulatory Developments on Sustainability Issues in Light of Delegated Regulation (EU) 2023/2772 (ESRS)
Authors: Martínez-Torres Virginia
Published: September 2024

Sustainability reports have undergone significant evolution with the implementation of Directive 2022/2464 (CSRD). Despite the standardization efforts through the European Sustainability Reporting Standards (ESRS) developed by EFRAG, in 2023, the European Commission proposed significant reductions in reporting requirements, with cuts of up to 50%. This step back in the requirements has caused uncertainty about the CSRD’s ability to ensure effective environmental sustainability reporting. The changes, formalized in Delegated Regulation (EU) 2023/2772, represent a turning point in regulating corporate sustainability, and their adequacy in achieving transparency and comparability objectives continues to be a matter of debate.
