FEATURES OF WEAR AND PROSPECTS FOR RESTORATION OF THE WORM AUGER SEGMENT OF A BEAD MILL
Authors: Herasimov Valerii , Plitchenko Serhii , Peremitko Valerii , Matyazh Illia
Published: June 2024

One of the most common problems of bead mills is the intensive wear of their working grinding segments, which negatively affects the quality of the crushed material and causes long-term downtime of the equipment, and, as a result, economic losses. Taking into account the identified problem, the purpose of the study is to analyze the working conditions and the nature of wear of the working surfaces of the segments of the bead worm shaft and justify the technology of their restoration. It was established that the main wear of the contact surfaces of the cast iron segments (ChKh1) is caused by their friction with the beads, which according to their chemical composition (55 % SiO2, 19.3 % СaO, 13.4 % Al2O3, 6.5 % B2O3, 4.2 % MgO) and hardness are an abrasive element relative to wearing surfaces. The nature and degree of loss of size and shape of the segments due to wear depends, among other things, on the diameter of the bead balls, which determines the waviness of the contact surface of the segment and the gradient of hardness values due to defamation. On the other hand, the working surfaces are affected by the technological suspension, which causes the appearance of the effect of cavitation wear, which consists in the formation of indentations on the surface after multiple repeated blows of the liquid. The conducted analysis of the operating conditions of the segments established a combined hydroabrasive wear mechanism of their working surfaces, which is explained by the simultaneous effect of abrasive bead elements and technological suspension. The nature of the intensity of the mentioned wear mechanism is uneven along the height of the worm screw, from mainly hydroabrasive for the upper segments to almost purely abrasive for the lower segments. Taking into account the determined mechanism of wear, it is proposed to restore the working surfaces of the segments by electric arc surfacing, and powder-coated wires of different chemical composition are used as surfacing materials. To clarify the influence of the chemical composition of the deposited metal on the mechanical properties of the restored layer, it is proposed to use powder-coated wires with different contents, primarily of carbon and chromium, which will allow to evaluate the resistance of the contact surfaces to both abrasive and hydroabrasive wear.

Authors: Pegley Kip
Published: June 2024

Background: While a small number of scholars explore how contemporary American soldiers consume music “in theatre” (in a war zone) to motivate themselves and protect their mental health, little research addresses how music functions for Canadian combatants.

Analysis: Case studies of two Canadian veterans illuminate the varied ways they used music to protect their mental health during their deployments in Afghanistan.

Conclusion and implications: This article demonstrates that Canadian soldiers listened to a wide range of music to cope while on tour and argues for music as a unique portal through which to understand soldiers’ deployment experiences.
Extreme Climate Events and Agricultural Commodity Markets
Authors:   , Shovon Mohammad
Published: June 2024

This article investigates the impact of extreme climate events on U.S. agricultural commodity markets, specifically focusing on corn and soybeans. Using event study methods and a comprehensive dataset of 254 extreme climate events for corn as well as 250 extreme climate events for soybeans in top ten corn & soybeans producing states of the USA between 1995 and 2023, we examine how storms, floods, extreme temperatures, and droughts affect the abnormal returns of these commodities. Our findings indicate that 22.04% of climate events significantly impact corn returns and 21.20% of climate events have significant impact on soybeans returns. Notably, extreme temperatures in the case of corn as well as storms in the case of soybeans emerge as the primary culprits, yielding the highest average cumulative abnormal returns. Moreover, we also find that the duration and interaction between GDP & U.S. import dependency significantly impact corn returns, whereas duration affects soybeans cumulative abnormal returns significantly following an extreme climate event. By shedding light on the vulnerability of agricultural markets to climate extremes, our study furnishes valuable insights for policymakers seeking to craft effective climate change adaptation strategies. Our findings underscore the imperative of bolstering agricultural markets’ resilience to these kind of events. Whether through diversifying portfolios, hedging against weather-related risks, or investing in climate-smart agricultural practices, our research provides a robust foundation for making well-informed decisions in navigating the intricate landscape of agricultural markets amidst climate uncertainty.

Superoxide Generating Activity of Nicotinamide Coenzymes
Authors: Sirota T. V
Published: June 2024

It has been shown that nicotinamide coenzymes (NADPH, NADH, NADP+, NAD+) are capable of generating superoxide anions (O2─●) in an alkaline environment. The superoxide-generating activity of coenzymes is associated with high pH values and is sensitive to SOD. However, nicotinamide itself, being a functional part of coenzyme molecules, does not have this property. Polarographic studies have shown that in the presence of coenzymes, molecular oxygen is consumed from the buffer, namely oxygen activation occurs due to the formation of O2-●. Based on the results obtained and in accordance with the literature, our observations suggest that the formation of adducts of nicotinamide, which is part of the coenzyme molecule, and hydroxyl anions (OH−) may lead to the formation of O2─●. Under mild conditions in the organism, the studied coenzymes, while performing their main functions, are expected to generate superoxide, meaning that they can be signaling molecules.

Published: June 2024

A theoretical conformational analysis was performed to study the conformational possibilities for thecasoxin C molecule (Tyr1-Ile2-Pro3-Ile4-Gln5-Tyr6-Val7-Leu8-Ser9-Arg10-OH). The potential functionof the system is chosen as a sum of non-valence, electrostatic and torsion interactions and the energy of hydrogen bonds. The low-energy conformations of the casoxin C molecule were found, the values of dihedralangles of the main and side chains of the amino acid residues that make up the molecule were determined,and the energy of intra- and interresidual interactions was estimated. It has been shown that the spatial structure of the casoxin C molecule is represented by conformations of eight shapes of the peptide skeleton. Theresults obtained can be used to elucidate the structural and structural-functional organization of casoxin molecules.
Development of the Concept
of “Gene” in the Academic Subject “Biology” for Grade 10 in the Light of Niels Bohr’s
Correspondence Principle
Authors: Krylova T. Y. , Sukhorukova L. N. , Goncharov M. A.
Published: June 2024

The relevance of the article is determined by the need to update the educational
content on the basics of genetics in the subject “Biology” for the 10th grade. It is
known that in most current textbooks the genetic section is built without reliance on the
methodology of theoretical cognition, the principle of historical continuity of theories of
genetics, which underestimates the cognitive capabilities of schoolchildren. The leading
component of theoretical knowledge that ensures its development is a concept. Thus,
genes are consistently concretized in the system of theories: starting from the teachings
of G. Mendel — to the chromosomal theory of heredity and from it — to the molecular theory
of the gene. The historical continuity of genetic theories serves as an ideal model of Niels
Bohr’s correspondence principle, according to which a new theory (as a more complete
one) does not override the previous one, but includes it as an independent fragment. The
construction of educational material in the light of the correspondence principle gives
an opportunity to “go beyond the subject”, to get acquainted with universal schemes of
development of scientific cognition. In this case, the concept of “gene” becomes an activity
unit of the content. The student “rediscovers” the process of concept emergence in thinking
and masters the ways of mental activity.

A PERSONAL MODEL AS AN IDEAL FOR IMITATION IN THE PEDAGOGY OF ORTHODOXY
Authors: Horin Dmitrii
Published: June 2024

The article considers the phenomenon of imitation in the pedagogy of Orthodoxy. The analysis of the use of the concepts of "example", "image", "ideal image", "personal sample", "ideal", "pedagogical ideal" and "goal" in the Russian pedagogical science is carried out. It is proved that all of them are concepts of the same order and are aimed at organizing the spiritual transformative activity of a person. From the point of view of pedagogy and psychology, the concept of "imitation" is considered and the tradition of its use in the pedagogy of Orthodoxy is studied. Following a personal model as an ideal for imitation in Orthodoxy correlates with the method of example in the pedagogical science. Based on acmeological, culturological and axiological approaches, the essence of the example in the pedagogy of Orthodoxy is revealed. It is proved that the method of example traditionally plays a special role in the educational system of Orthodoxy. An example in this case is the saints glorified in this face by the Orthodox Church. A special role is played by descriptions of the life of saints as a means of upbringing and education.

Authors: Waldhelm Andy , McElroy Lauren , Buescher Cameron , Barnett Haley , Cunningham Jessica , Richards Jared , Schwarz Neil
Published: June 2024

BACKGROUND:

Test selection during the return to sport evaluation is an important aspect of ensuring athletes are safe to return to competition.

OBJECTIVE:

To assess the test-retest and inter-rater reliability of two new single leg hamstring bridge tests (SLHBT) and the relationships between these new tests and isokinetic strength of the quadriceps and hamstrings.

METHODS:

Thirty healthy college students completed the study. Two testing sessions were held three to seven days apart. Session one, participants performed two SLHBT as well as concentric isokinetic strength tests for the hamstring and quadriceps at 60, 180 and 300∘/sec. The participants performed only the two SLHBT during the second session. The first SLHBT, participants performed as many repetitions as possible of the SLHBT in 30-sec, while the second test measured how quickly the participants could perform five repetitions. Intraclass Correlation Coefficients (ICC2,1) were used to assess test-retest reliability while ICC(3,1) were used to test inter-rater reliability.

RESULTS:

The test-retest reliability for the SLHBTs was moderate to good, with ICC(2,1) ranging from 0.68 to 0.75, while the inter-rater reliability were excellent with ICC(3,1) all above 0.98. There were significant correlations between the SLHBT and the isokinetic tests, but all correlations were low to moderate.

CONCLUSION:

This study found good to excellent reliability with the new SLHBT and poor to moderate correlations were noted Therefore, SLHBT may not be an alternative to test hamstring test during the RTS evaluation due to the multiple compensatory strategies athletes may have.

Authors: Ito Kazuhiro , Maeshima Etsuko , Saito Koichi , Koshiba Hiroya , Nakamata Takaaki , Yamaguchi Kazuki , Maegawa Ryota , Hatanaka Yasuhiko
Published: June 2024

BACKGROUND:

Hip flexion angle-torque may not be measured accurately due to the measurement posture.

OBJECTIVE:

Maximum isometric hip flexion torque was measured while excluding the effects of postural retention function and compensatory motion.

METHODS:

Experiment 1: Maximum isometric flexion torque of the hip joint was measured at 0∘, 30∘, 60∘, 90∘, and 105∘ in 195 participants. Experiment 2: Maximum isometric hip flexion torque of 33 participants was measured in standing and supine position at 0∘ hip flexion and in end-sitting and supine position at 105∘.

RESULTS:

Experiment 1: No interaction was observed between sex and hip angle, and hip flexion torque was minimum at 0∘ hip flexion and maximum at 105∘ hip flexion in both sexes ([Formula: see text] 0.01). Experiment 2: An interaction between measurement position and hip angle was observed, with maximum isometric flexion torque being greater in the supine position than in the standing position ([Formula: see text] 0.01). Maximum isometric hip flexion torque was greater at 105∘ than at 0∘ flexion ([Formula: see text] 0.01).

CONCLUSIONS:

Maximum isometric hip flexion torque showed greater joint angle-torque characteristics in deep flexion than in shallow flexion of the hip when excluding the effects of postural retention function and compensatory motion.
Induced Muscle and Liver Absence of Gne in Postnatal Mice Does Not Result in Structural or Functional Muscle Impairment

Published: June 2024

Background:

GNE Myopathy is a unique recessive neuromuscular disorder characterized by adult-onset, slowly progressive distal and proximal muscle weakness, caused by mutations in the GNE gene which is a key enzyme in the biosynthesis of sialic acid. To date, the precise pathophysiology of the disease is not well understood and no reliable animal model is available. Gne KO is embryonically lethal in mice.

Objective:

To gain insights into GNE function in muscle, we have generated an inducible muscle Gne KO mouse. To minimize the contribution of the liver to the availability of sialic acid to muscle via the serum, we have also induced combined Gne KO in liver and muscle.

Methods:

A mouse carrying loxp sequences flanking Gne exon3 was generated by Crispr/Cas9 and bred with a human skeletal actin (HSA) promoter driven CreERT mouse. Gne muscle knock out was induced by tamoxifen injection of the resulting homozygote GneloxpEx3loxp/HSA Cre mouse. Liver Gne KO was induced by systemic injection of AAV8 vectors carrying the Cre gene driven by the hepatic specific promoter of the thyroxine binding globulin gene.

Results:

Characterization of these mice for a 12 months period showed no significant changes in their general behaviour, motor performance, muscle mass and structure in spite of a dramatic reduction in sialic acid content in both muscle and liver.

Conclusions:

We conclude that post weaning lack of Gne and sialic acid in muscle and liver have no pathologic effect in adult mice. These findings could reflect a strong interspecies versatility, but also raise questions about the loss of function hypothesis in Gne Myopathy. If these findings apply to humans they have a major impact on therapeutic strategies.
Portable technology for postural control measurement: Comparing head position with center of pressure data
Authors: Harel Daphna , Lubetzky Anat Vilnai
Published: June 2024

BACKGROUND: Standing is a basic human function that healthy adults take for granted, yet it is a complex perceptual-motor process that requires sensation of position and motion from the sensory systems. OBJECTIVE: We assessed agreement between center of pressure data from a laboratory force-platform and head position data from an HTC Vive head-mounted display (HMD) for the evaluation of standing postural control. We investigated the impact of different statistical choices when assessing the relationship between two measurements. Specifically: 1) How does correlation and agreement statistics relate before and after logarithmic transformation? 2) Is there systemic or proportional bias between the force-platform and HMD measurements? METHODS: We tested 37 adults (26 controls, 11 with unilateral vestibular hypofunction) standing on foam, observing a static or dynamic visual scene projected from the HMD. We quantified anterior-posterior and medio-lateral sway via Directional Path, Root Mean Square Velocity, Variance, and Power Spectral Density (PSD) from a force-platform and the HMD. RESULTS: Intra-class correlations (ICCs) were moderate-to-good for the non-transformed data and good-to-excellent after logarithmic transformation for all outcomes except for PSD above 1 Hz. Correlations were higher than ICCs. Bland-Altman plots indicated proportional bias but not after logarithmic transformation. CONCLUSIONS: Both devices correlated linearly, and measure people’s postural responses but cannot be used interchangeably, mostly because they appear to diverge with larger sway as evident on Bland-Altman plots of non-transformed data. Agreement between devices was excellent for low frequency movement but poor for high frequency small corrective movements.

Authors: Chen Pan , Wang Xiaojie , Yan Pijun , Jiang Chunxia , Lei Yi , Miao Ying
Published: June 2024

BACKGROUND: Dysfunctions in metabolism and endocrine systems are outcomes of disruptions in human physiological processes, often leading to disease onset. External factors can hinder the human body’s innate capacity for self-regulation and healing, particularly when immune responses are compromised, allowing these factors to interfere with normal bodily functions directly. OBJECTIVE: To explore the effect of uric acid expression water in blood on the occurrence of atrial fibrillation in patients with hyperthyroidism, the expression level of uric acid in the blood and other physiological indexes were compared between patients with no symptoms of atrial fibrillation and patients with hyperthyroidism with symptoms of atrial fibrillation, to find the correlation between them. METHODS: A group of 112 hyperthyroidism patients who were admitted to our hospital from September 2019 to March 2020 were chosen and split into two groups. The control group consisted of 56 individuals (21 men and 35 women) aged between 16 and 86 years old, with an average age of 46.23 years (± 7.63). The observation group consisted of 56 individuals (24 males and 32 females) between 15 and 79 years, with an average age of 53.44 years (± 8.91). RESULTS: In the patients who were not treated with drugs before hospitalization the disease course and symptoms varied. The patients’ clinical medical and demographic data were recorded and the patients’ physiological indexes were obtained through blood tests and analysis. The differences between the two groups were analyzed by renal function, blood lipid index, thyroid function, and cardiac ultrasound, and these influencing factors were analyzed by regression analysis. The research adhered to ethical norms and ensured clear data presentation by using a rigorous technique to compare uric acid levels and physiological indicators among various patient groups. CONCLUSION: The study concentrated on the validation, repeatability, and contextual interpretation of data to provide a robust and rigorously scientific comparison. The most common is the increase of uric acid in the blood, which can induce other diseases, and atrial fibrillation is one of the most common diseases of cardiovascular diseases.

Published: June 2024

BACKGROUND: To enhance the self-management ability of elderly diabetes mellitus (DM) patients, priority should be given to the accurate evaluation of their current self-management ability, and then provide corresponding guidance. OBJECTIVE: To explore the application value of Diabetes Self-Management Behaviors among Older Koreans (DSMB-O) in self-management of elderly patients with type 2 diabetes mellitus (T2DM). METHODS: Using convenient sampling, this study retrospectively collected the clinical data of 215 elderly patients with T2DM who were admitted to our hospital from June 2020 to June 2022. Enrolled patients were divided into an effective-control group (n= 80) and an ineffective-control group (n= 135) based on whether the glycated hemoglobin (HbA1C) was < 7.5% for further comparison of the collected data. RESULTS: There were statistically significant differences in the comparison of the proportion of diabetes mellitus (DM) course (χ2= 26.000, P< 0.001), DSMB-O score (17.67 ± 4.07 VS 14.67 ± 4.70 points, t= 4.582, P< 0.001), and Summary Diabetes Self Care Activity (SDSCA) score (43.16 ± 11.17 VS 37.58 ± 12.47 points, t= 5.492, P< 0.001) between the two groups. The total score of DSMB-O was negatively correlated with both HbA1c (r=-0.281, P< 0.001) and complications (r=-0.193, P= 0.004); moreover, the total score of SDSCA was also negatively correlated with both HbA1c (r=-0.234, P< 0.001) and complications (r=-0.153, P= 0.025). Among various dimensions of DSMB-O, active exercise (OR= 0.699, 95%CI: 0.541 ∼ 0.902) and blood glucose monitoring (OR= 0.603, 95%CI: 0.431 ∼ 0.817) were protective factors for T2DM patients with HbA1c levels < 7.5%. The area under the curve (AUC) of SDSCA score and DSMB-O score predicting self-management level in elderly T2DM patients was 0.643 (95%CI: 0.611 ∼ 0.756) and 0.716 (95%CI: 0.689∼ 0.774), respectively. CONCLUSION: DSMB-O exhibits a higher accuracy in predicting the self-management level of elderly patients with T2DM than that of SDSCA. Regular exercise, medication, blood glucose monitoring, and reducing the risk of complications are all intimately associated with the control of blood glucose.
Protective effect of unsaturated fatty acids on cognitive impairment in CKD patients: Results from the National Health and Nutrition Examination Survey (2011–2014)

Published: June 2024

BACKGROUND: It is still unknown whether unsaturated fatty acids (UFA) have the same effect on preventing cognitive impairment in chronic kidney disease (CKD) patients as in healthy people. OBJECTIVE: To investigate the protective effect of dietary UFA intake and proportion on cognitive impairment in patients with CKD. METHODS: We extracted data from the National Health and Nutrition Examination Survey (NHANES, 2011–2014) on participants with a previous diagnosis of CKD and at least one complete cognitive assessment (Consortium to Establish a Registry for Alzheimer’s Disease test, Animal Fluency Test and Digit Symbol Substitution Test). We used the lower quartile of the total scores of these three tests as the cut-off point, and divided the participants into two groups of normal cognitive performance and low cognitive performance to extract participants’ intake of various UFA from the NHANES dietary module. The data were weighted using weighting parameters included in NHANES, and logistics regression and restricted cubic spline were used to analyze the protective effect of UFA intake on cognitive impairment in CKD participants. RESULTS: We found that participants with low cognitive performance all had significantly lower intakes of total monounsaturated fatty acids, total polyunsaturated fatty acids, ω-3 UFA, ω-6 UFA and ω-9 UFA than participants with normal cognitive performance (p< 0.05), and the ω-6 UFA and ω-9 UFA had the most significant protective effects on cognitive impairment of participants. We also discovered that oleic and linoleic acids play important roles in protecting against cognitive impairment in CKD participants. The protective effect of oleic acid, but not linoleic acid, on cognitive impairment showed a nonlinear relationship. The changes in the proportion of monounsaturated fatty acids to polyunsaturated fatty acids, ω-6 UFA to ω-3 UFA, and oleic acid to linoleic acid did not affect the risk of cognitive impairment in CKD participants. CONCLUSIONS: UFA can reduce the risk of cognitive impairment in CKD patients, especially oleic acid and linoleic acid have a more obvious protective effect on cognitive impairment in patients with CKD. Among them, the protective effect of linoleic acid on cognitive impairment was continuously enhanced with the increase of intake, indicating that linoleic acid may be the most important UFA to reduce cognitive impairment in CKD patients.

Submerged arc welding. Influence of welding flux on physical and mechanical properties of steel. Welding of high-strength steel grades
Authors: Baidimirov M. A.
Published: June 2024

Welding ceramic fluxes have several advantages over fused ones, for example, the possibility of alloying the weld metal by adding alloying additives, the second advantage is the environmental friendliness of the flux production, all components are heat treated without melting. Ceramic welding flux in most cases consists of two parts: the slag phase and alloying additives. The article presents the results of experimental work on studying the influence of ceramic welding flux on the properties of weld metal. The physical meaning of the slag phase of ceramic welding fluxes is demonstrated. The main characteristics of ceramic welding fluxes are given, it is shown, how the basicity of the slag phase of the flux affects the melting point and, together with it, the welding process. Depending on the basicity of the welding flux slag, the welding stroke can be adjusted. The physical, chemical and electrochemical parameters of a welding bath are similar to those of a steelmaking bath, but the fundamental difference is the reaction rate. To date, the effect of ceramic welding fluxes has not been fully studied. A sufficient number of factors can affect the final properties of the seam metal, in particular: chemical composition of the flux; chemical composition of the wire and base metal; the amount of alloying additives in the flux; welding modes (affect the degree of assimilation of alloying components); type of cutting of the welded product. The article also presents the results of electron microscopy of slag crusts of molten welding flux. According to the results of electron microscopy, it was possible to capture the process of oxidation and subsequent reduction of zirconium, zirconium is one of the main auxiliary elements contributing to a favorable effect on the properties of the seam metal, but at the same time, zirconium was not detected during chemical analysis of the seam metal.

The quality indicators of coke used for agglomerate and pig iron production at the enterprise are analyzed. It is shown that the moisture content in coke is unstable and the particle size distribution is heterogeneous. The values of coke quality indicators such as M10 abrasion, coke strength after reaction (CSR), and coke reactivity index (CRI) do not meet the recommendations of domestic and foreign scientists. Measures are proposed to improve the quality of coke used at the enterprise. It is established that the relatively low quality of agglomerate produced at JSC “Ural Steel” is associated with an unsatisfactory particle size distribution of agglomerate components, a significant content of small fractions in the pelletised agglomerate mix, and low granule strength. These deficiencies, combined with the lack of exhausters on agglomeration machines № 1‒3 and significant harmful suction at the sides of the pallets and ends of the agglomeration machines, prevent an increase the rarefaction in the collectors, height of the sintering layer, reduction in solid fuel consumption in the mix, improvement of gas permeability, and granule strength of the agglomerate. The chemical composition and strength characteristics of pellets produced by “Mikhailovsky GOK named after A. V. Varichev” with increased iron and magnesia contents are provided. The use of these pellets in the blast furnace burden can improve the technical and economic performance of the blast furnace process. The technology and production indicators of pig iron in blast furnace № 1 of the enterprise are analyzed. Feasible methods for reducing coke consumption and increasing the productivity of the blast furnace are developed for JSC “Ural Steel”.

This study discusses administrative law enforcement in the context of spatial planning, which involves the construction of spatial planning policy based on Law Number 26 of 2007 concerning Spatial Planning (UU 26/2007). This research uses a literature study method to analyze the differences between the space utilization control system used in the old Spatial Planning Law (UU No. 24 of 1992) and the new one (UU No. 26 of 2007). The research results show that the new Spatial Planning Law adopts the zoning concept, where space utilization is based on zoning regulations which stipulate zone-based rules. In a concrete case in West Jakarta, violations of spatial planning provisions resulted in the demolition of buildings carried out by the government after giving a warning letter. The form of administrative sanctions imposed includes several options, including building demolition. Keywords: Law Enforcement, Administrative Sanctions, Spatial Planning Abstrak Studi ini membahas penegakan hukum administrasi dalam konteks penataan ruang, yang melibatkan konstruksi kebijakan aturan tata ruang berdasarkan Undang-Undang Nomor 26 Tahun 2007 tentang Penataan Ruang (UU 26/2007). Penelitian ini menggunakan metode studi pustaka untuk menganalisis perbedaan antara sistem pengendalian pemanfaatan ruang yang digunakan dalam UU Penataan Ruang yang lama (UU No. 24 Tahun 1992) dan yang baru (UU No. 26 Tahun 2007). Hasil penelitian menunjukkan bahwa UU Penataan Ruang yang baru mengadopsi konsep zoning, di mana pemanfaatan ruang didasarkan pada peraturan zoning yang menetapkan aturan berbasis zona. Dalam kasus konkret di Jakarta Barat, pelanggaran terhadap ketentuan penataan ruang mengakibatkan pembongkaran bangunan yang dilakukan oleh pemerintah setelah memberikan surat peringatan. Bentuk sanksi administrasi yang diberlakukan mencakup beberapa opsi, termasuk pembongkaran bangunan. Kata kunci: Penegakan Hukum, Sanksi Administrasi, Penataan Ruang

Published: June 2024

The rise in online banking fraud, driven by the underground malware economy, underscores the crucial need for robust fraud analysis systems. Regrettably, the majority of existing approaches rely on black box models that lack transparency and fail to provide justifications to analysts. Additionally, the scarcity of available Internet banking data for the scientific community hinders the development of effective methods. This paper presents a decision support system meticulously crafted to identify and thwart fraud in online banking transactions. The chosen approach involves the application of a Random Forest decision tree model—a supervised machine learning technique renowned for its effectiveness in enhancing fraud detection within online banking systems, yielding substantial real-world impact. Constant monitoring of both the system and data ensures optimal performance, enabling timely responses to deviations. The overarching objective of the system is to furnish analysts with a powerful decision support tool capable of preempting financial crimes before they occur.

Резюме. Стан психофізіологічних функцій спортсмена безумовно залежить від особливостей центральної нервової системи, що позначається на процесі формування та вдосконалення спеціальних рухових навичок впродовж спортивної діяльності. Саме тому психофізіологічна діагностика є одним із актуальних напрямів сучасної спортивної науки. Мета. Оцінка функціонального стану центральної нервової системи за показниками реакції на рухомий об’єкт кіберспортсменів у зв’язку з рівнем прояву когнітивних функцій. Методи. Тести «Кільця Ландольта», «Зорова пам’ять», «Пам’ять на числа», «Встановлення закономірностей», «Домінуюча система сприйняття», «Три слова». Результати. Під час дослідження було виконано оцінювання показників реакції на рухомий об’єкт, показників когнітивної сфери кіберспортсменів (що характеризують рівень концентрації уваги, обсяг та точність короткочасної зорової пам’яті, особливості протікання аналітико-синтетичної діяльності під час вирішення наочно-образних завдань, домінуючий тип сприйняття, особливості творчої уяви) та взаємозв’язки між ними. Кіберспортсмени продемонстрували вищу точність у реакції на рухомий об’єкт порівняно із студентами, які не займаються комп’ютерними іграми. За результатами дослідження розроблено модельні характеристики точності реакції на рухомий об’єкт кіберспортсменів, які можуть стати основою для створення експрес-діагностики функціонального стану центральної нервової системи кіберспортсменів.
