Smart development in the making: Links between commuting, digital technologies and the demand for e-government applications in Hungary
Authors: Kaiser Tamás
Published: September 2024

Although various actors have examined the user acceptance of e-government developments, less attention has so far devoted to the relationship between attitudes of certain commuter groups against digital technologies and their intention to engage in productive time-use by mobile devices. This paper aims to fill this gap by establishing an overall framework which focuses on Hungarian commuters’ attitudes toward e-government applications as well as their possible demands of developing them. Relying on a representative questionnaire survey conducted in Hungary in March and April 2020, the data were examined by a machine learning and correlations to identify the factors, attitudes and demands that influence the use of mobile devices during frequent commuting. The paper argues that the regularity of commuting in rural areas, as well as the higher levels of qualification and employment status in cities show a more positive, technophile attitude to new ICT and mobile technologies that strengthen the demands for digital development, with special regard to optimising e-government applications for certain types of commuting groups. One of the main limitations of this study is that results suggest a picture of the commuters in a narrow timeframe. The findings suggest that developing e-government applications is necessary and desirable from both of the supply and demand sides. Based on prior scholarly knowledge, no research has ever analysed these correlations in Hungary where commuters are among the European citizens who spend extensive time with commuting.
Ремонт керамической посуды в неолите и энеолите (по материалам крайнего Северо-Востока Европы)
Authors: Карманов Виктор Николаевич
Published: September 2024

Публикуются региональные данные о ремонте керамической посуды в неолите и энеолите (VI – III тыс. до н.э.). Свидетельства древнего ремонта керамической посуды – это противоположные отверстия разного вида вблизи краев трещин лопнувшего сосуда или трещин, угрожающих его целостности, а также остатки адгезивных веществ, герметизировавших ремонтный шов и сверлины. В результате определено, что древнейшие свидетельства ремонта посуды в регионе связаны уже с ранним гончарством (VI тыс. до н.э.). Потребность в починке керамики возрастает к финальному неолиту (вторая пол. IV тыс. до н.э.) и снижается в энеолите (III тыс. до н.э.). Использование отверстий со скрепками из органических материалов и герметиков в диахронии также неравномерно. В комплексах раннего неолита применение адгезивных материалов не зафиксировано, напротив, оно возрастает к финальному неолиту, а в энеолите может являться единственным способом ремонта. Методом газовой хромато-масс-спектрометрии изучены пять образцов герметика чужяъельской культуры финального неолита – энеолита. Определено, что адгезивные материалы – это деготь, полученный «двухгоршечным» способом – нагревом исходного сырья в одной емкости и одновременным стеканием готового продукта в другой сосуд. Комплекс действий, инструментов и материалов для починки керамики обуславливает познавательные возможности этой категории источников. Как и любые доказательно восстановленные «биографии» артефактов, «истории» горшков позволяют рассказать о поведении людей и оценить их потребности и образ жизни.
Степь и волго-камские финны и угры: проблема контактов во второй половине I тыс. н.э. в археологическом выражении (на примере поясных наборов)
Authors: Иванов Владимир Александрович
Published: September 2024

Опираясь на результаты исследований Т.Б. Никитиной и Н.Б. Крыласовой по типологии и хронологии поясной гарнитуры из могильников VIII–XIII вв. Вятско-Ветлужского междуречья (древние марийцы) и Среднего Прикамья (финно-пермяки, носители родановской археологической культуры), автор статьи приводит сравнительно-географическую статистику распространения в регионе целых поясных наборов, состоящих из пряжки, накладок и наконечника. Полученные результаты показывают, что в VIII–IX вв. целые пояса концентрируются в основном в могильниках древних угров-венгров Прикамья и Южного Предуралья, по частоте встречаемости значительно превосходя могильники марийцев и мордвы. Вероятно, именно вследствие миграции венгров из Предуралья пояса и их детали могли отложиться и в могильниках древней мордвы. В X–XI вв. «статистическое лидерство» в использовании целых поясов переходит к поволжским финнам – марийцам. У угров Южного Предуралья пояса не встречаются вообще, а у кочевников-печенегов – единицами. Менее частое распространение этих изделий у прикамских финно-пермяков – носителей родановской культуры – при наличии у них собственного производства, вероятно, объясняется влиянием ислама, центром распространения которого в Прикамье был болгарский город-форпост Афкула.
Сходство и различие наборных поясов IX-XI вв. Ветлужско-Вятского междуречья и Пермского Предуралья
Authors: Крыласова Наталья Борисовна
Published: September 2024

К юбилею известного российского археолога Т.Б.Никитиной в статье оценивается ее вклад в изучение средневековых наборных поясов. Могильники Ветлужско-Вятского междуречья отличаются уникальной сохранностью поясов, что позволило не только всесторонне изучить отдельные элементы наборных поясов, но и проследить их состав, конструкцию и особенности ношения. По материалам Рождественского могильника в Пермском крае предпринята апробация классификации поясов, разработанной Т.Б. Никитиной. Как показали результаты исследования, классификация вполне универсальна и применима для анализа поясов различных территорий. На Рождественском могильнике выделены пояса в один и полтора оборота. Некоторые по составу абсолютно идентичны встреченным в Ветлужско-Вятском междуречье, и можно предполагать, что они поставлялись из одного центра. Есть пояса в целом схожие, но имеющие в своем составе, к примеру, не один, а два основных типа накладок, а есть местные пояса, включающие накладки, характерные преимущественно для Пермского Предуралья. Пояса в два оборота, вероятно, свойственны исключительно для культуры населения Ветлужско-Вятского междуречья. Подобные исследования существенно расширяют возможности поясной гарнитуры как археологического источника.

Ранний неолит Барабинской лесостепи: проблемы и особенности культуры
Authors: Молодин Вячеслав Иванович
Published: September 2024

В октябре 2024 г. научное сообщество отмечает 70-летний юбилей крупного ученого и организатора науки А.А. Выборнова. Особое значение в его творчестве имеют проблемы неолита. В этой связи вопросы раннего неолита Западной Сибири представляют для будущего юбиляра несомненный интерес. Барабинская ранненеолитическая культура выделена сравнительно недавно, однако привлекает постоянное внимание специалистов. Настоящая работа посвящена отдельным проблемам культуры, которые находятся в стадии разработки. Полученная серия радиоуглеродных дат позволяет датировать культуру в пределах конца VIII – начала VI тыс. до н.э., в настоящее время ведется разработка ее периодизации. Особой спецификой культуры является своеобразная по технологии и морфологии плоскодонная глиняная посуда. Представительный каменный инвентарь культуры характеризуется пластинчатой техникой исполнения, корнями уходящей в период верхнего палеолита. Для Барабинской культуры характерно широкое использование кости, из которой выполнялись характерные исключительно для данной культуры изделия, и вкладышевых орудий. Особенностью культуры является наличие на поселениях специальных ям для квашения рыбы, содержащих ритуальные приклады в виде различных животных или их частей. Культура представляется автохтонной, однако отчетливо фиксируется ее западные, юго-западные связи.
Неолитизация лесостепного и лесного Среднего Поволжья: разные выражения одного процесса
Authors: Андреев Константин Михайлович , Кудашов Александр Сергеевич
Published: September 2024

Представленная статья посвящена анализу процесса перехода в новый каменный век в двух сопредельных регионах. Дана характеристика природно-климатических условий и кремневых комплексов мезолитического и ранненеолитического периодов. Для лесного Среднего Поволжья приводится описание жилищных сооружений, характерных для обеих эпох. Также осуществляется поиск аналогий ранней керамике регионов и определяются вероятные источники ее заимствования. Учитываются последние разработки в области абсолютного датирования интересующих комплексов и результаты анализа технологии изготовления посуды. Различия в материальной культуре мезолитического и ранненеолитического населения лесостепного Поволжья оказываются весьма значительными. Представленное обстоятельство позволяет допускать прямую миграцию населения в регион из областей, население которых было знакомо керамическим производством, что способствует его неолитизации. Для лесного Среднего Поволжья характерна преемственность в традиции кремнеобработки между средним и новым каменным веками. Определенная близость фиксируется в приемах домостроительства обоих периодов. Новация – керамика – своим происхождением, вероятно, связана с населением лесостепной зоны. Учитывая ряд приведенных обстоятельств, допустимо рассматривать неолитизацию лесного Среднего Поволжья в результате диффузии отдельных групп южного населения (елшанская культура). Они не оказывают существенного влияния на материальную культуру аборигенного населения, а традиция изготовления глиняной посуды трансформируется в результате адаптации местным населением.
Quiet Disquietude
Authors: E. Aslan Ali
Published: September 2024

In describing our ideals of dignity and the like as fictions, I reflect on and uphold a non-pejorative understanding of fiction and how that stance is abused by power, which is unable to recognize any interiority except its own. To allow for that narrative of inner life, I accept the negative charge of the dialectic I am already thrown into; only then can I author my particularity/interiority and respond to the master enframing scheme which conceals our inner lives. All this movement and recognition of disquiet requires a certain quiet, a nothingness as fictitious and factful as the ideals that will spring forth from it. Not without that reflection can I step into my own being, to take account of where I might be wrong, to truly inhabit and entertain that which fascinates me, and to maintain a metaphysics wherein I am not only other but also open to the call of another. This is a reorientating quiet, an invitation to a creative nihil.
Adaptive Wind Field Estimation Using an Empirical Bayesian Approach
Authors: Kiehn Daniel , Schultz Julius , Fezans Nicolas , Römer Ulrich
Published: September 2024

In lidar-based gust load alleviation, the wind profile ahead of the aircraft cannot be measured directly but has to be reconstructed (estimated) based on the acquired line-of-sight measurements. Such wind reconstruction algorithms typically include regularization in order to adequately handle the noise within the data. This paper presents an empirical Bayesian approach to choosing optimal regularization parameters for any given set of measurements. Using simulations of flight through turbulence, the Bayesian approach is compared with a former approach (based on engineering guess) and an omniscient optimizer, which yields the best achievable results for a constant set of parameters by using the full knowledge of the wind field. The Bayesian approach is shown to outperform the engineering guess and performs close to the omniscient optimizer while purely relying on the lidar measurement data.
Medial meniscal posterior root tear – A current concept review
Authors: Kumar Amit , Vijay Vipul , Vaish Abhishek
Published: September 2024

Menisci are crucial structures in the knee joint for the adequate distribution of hoop stresses. Their significance in preventing early knee osteoarthritis has been acknowledged due to the rapid progression of osteoarthritis in knees following meniscectomy. The anatomy of menisci has been studied in detail with an increased understanding of the importance of meniscal root attachments. This review aims to provide an evaluated summary of the anatomical, biochemical, and functional aspects that are relevant in the clinical context of meniscus root attachments, alongside contemporary strategies for accurately diagnosing and treating common injuries affecting these attachments. We also propose an algorithm for managing medial meniscus root tears which may be beneficial for the readers. We did an up-to-date literature search on PubMed, Scopus, and Google Scholar database, using the keywords ‘meniscus’, ‘meniscal root’, ‘sports injury’, and ‘arthroscopy’ in April 2024 and filtered out the relevant literature for this review on the articles that were published in English. The management of root tears requires a high level of suspicion which is crucial for diagnosis, identifying subtle signs on radiology, and employing specific methods for root repair. The tears or avulsions within one centimeter of the tibial attachment of the medial meniscus posterior root are called medial meniscus posterior root tears. These injuries cause a functional meniscal deficiency, resulting in knee problems unfavorable to biomechanics. Numerous methods have been created to tackle meniscus root tears., with many demonstrating promising outcomes in terms of complete healing.

INFLUENCE OF INTERFACE CURVATURE AND SOLUTION NONIDEALITY ON THE HENRY’S LAW CONSTANTS
Authors: Кошоридзе С.И.
Published: September 2024

Парциальное давление газа, растворенного в воде, зависит от кривизны границы раздела вода-пар в соответствии с формулами Кельвина и Гиббса. Кроме того, вблизи вогнутой поверхности водный раствор несовершенен. Эти факторы обусловливают размерную зависимость констант закона Генри газов, содержащихся в нанопузырьках. В работе предложен метод расчета реальных констант Генри для некоторых газов.

The partial pressure of a gas dissolved in water depends on the curvature of the water-vapor interface according to the Kelvin and Gibbs formulas. In addition, near the concave surface, the water solution is imperfect. These factors cause the size dependence of the Henry’s law constants of gases contained in nanobubbles. The paper proposes a method for calculating the real Henry’s constants for some gases.

Published: September 2024

Предложено инженерно-физическое решение проблемы зачистки обогащенной рудной мелочи с почвы выработанного пространства гидромеханическим способом. Сущность способа заключается в том, что рудная мелочь под воздействием струи воды высокого давления перемещается небольшими объемами на скреперную дорожку и далее транспортируется по ней механическим способом до аккумулирующей выработки. Применение предлагаемого способа гидромеханической зачистки рудной мелочи позволит уменьшить потери отбитой руды и получить экономический эффект от повышения производительности труда и извлечения практически всей ранее отбитой и обогащенной руды.

An engineering and physical solution to the problem of stripping enriched ore fines from the soil of the developed space by a hydro-mechanical method is proposed. The essence of the method is that the ore fines under the influence of a high-pressure water jet are moved in small volumes to the scraper track and then transported along it mechanically to the accumulating production. The use of the proposed method of hydro-mechanical cleaning of ore fines will reduce the loss of broken ore and get an economic effect from increasing labor productivity and extracting almost all previously broken and enriched ore.
Leveraging a separation of states method for relative binding free energy calculations in systems with trapped waters
Authors: Wagle Swapnil , Merz Pascal , Ge Yunhui , Bayly Christopher , Mobley David
Published: September 2024

Methods for calculating the relative binding free energy (RBFE) between ligands to a target protein are gaining importance in the structure-based drug discovery domain, especially as methodological advances and automation improve accuracy and ease of use. In an RBFE calculation, the difference between the binding affinities of two ligands to a protein is calculated by transforming one ligand into another, in the protein-ligand complex, and in solvent. Alchemical binding free energy calculations are often used for such ligand transformations. Such calculations are not without challenges, however; for example, it can be challenging to handle interfacial waters when these play a crucial role in mediating protein-ligand binding. In some cases, the exchange of the interfacial waters with solvent water might be very infrequent in the course of typical molecular simulations, and such interfacial waters can be considered trapped on the simulation timescale. In these cases, RBFE calculation between two ligands, where one ligand binds with a trapped water while the other ligand displaces it, can result in inaccuracies if the surrounding water structure is not sampled adequately for both ligands. So far, a popular choice for treating the trapped waters in RBFE calculations is to combine free energy calculations with enhanced sampling methods that insert/delete waters in the binding site. Despite recent developments in the enhanced sampling methods, they can result in hysteresis in the RBFE estimate, depending on whether the simulations were started with or without the trapped waters. In this study, we introduce an alternative method, separation of states, to calculate the RBFE between ligand pairs where the ligands bind to the protein with different numbers/positions of trapped waters. The separation of states approach treats the sampling of the trapped waters separately from the free energy calculation of the ligand transformation. In our method, a trapped water in protein's binding site is decoupled from the system first, and the cavity created by its decoupling is stabilized. We then grow a larger ligand into this cavity-- a ligand that is known to displace the trapped water. In this study, we show that our method results in precise and accurate estimates of RBFEs for ligand pairs involving the rearrangement of trapped water via RBFE calculations for five such ligand pairs. We have optimized our simulation protocol to be suited for large distributed computational resources and have automated our RBFE calculation workflow.
Site-Selective and Late-Stage Deuteration of (Hetero)arenes with Supported Iridium Nanoparticles
Authors: Yao Chengbo , Copéret Christophe
Published: September 2024

Deuterated compounds have emerged as critical tools across diverse research areas, including pharmaceuticals, where deuterium incorporation can modulate the absorption, distribution, metabolism, and excretion (ADME) prop-erties of drugs. In this study, we report the development of a novel hydrogen/deuterium (H/D) exchange catalyst based on supported iridium nanoparticles, which enables selective deuteration of arenes and heteroarenes under mild conditions. Using C6D6 as the deuterium source, our catalytic system achieves high chemo- and regioselectivity, avoiding the common side reactions such as hydrogenation and dehalogenation observed with traditional heteroge-neous catalysts. Notably, the deuteration occurs selectively at the para- and meta-C(sp2)–H bonds, leaving ortho C(sp2)–H and C(sp3)–H bonds intact, and exhibits broad functional group tolerance, including with ketones, amides, alkenes, aryl ethers, and acidic protons. The heterogeneous nature of the catalyst was confirmed via filtration and mercury drop tests. This work presents a novel catalytic system for regioselective deuteration of complex molecules, offering complementary site selectivity to existing homogeneous and heterogeneous methods and the possibility to be used in the late-stage deuteration of pharmaceuticals.
Design, Modelling and Fabrication of a Fault Tolerant 1 T
Superconducting Applied-Field Module for a kW-class
Plasma Rocket
Authors: Olatunji Jamal , Glowacki Jakub
Published: September 2024

In 2022, Paihau-Robinson Research Institute developed a 1 T superconducting
electromagnet cooled by a space rated cryocooler and successfully integrated it with a kilowatt-class plasma rocket, in collaboration with the Shockwave and Space Propulsion Laboratory at Nagoya University. The use of superconductors reduced the input power by over 99%, generated magnetic fields three times stronger, and by using a space-rated
miniaturised cryocooler, the use of liquid cryogen was eliminated. Therefore, for thrusters that require a strong external magnetic field – such as an applied-field magnetoplasmadynamic thruster – this represents the first system that could reasonably be
flown in space. This paper discusses the design, fabrication, and testing of the superconducting
coils at RRI for thrusters. Special attention is paid to preventing a ‘quench’, a major fault mode for superconducting coils. If part of the cryogenic coils is heated above the critical temperature, the superconducting state is destroyed. The energy stored in the magnetic field is dissipated suddenly, which can permanently destroy the superconducting system. Despite numerous tests with the plasma rocket, the superconducting electromagnet never quenched, even with large heat loads during plasma generation. This paper therefore also discusses how this fault tolerance was achieved.
The Correlation between Bullying, Academic Emotion and Teacher Support in Baccalaureate Nursing Education
Authors: Hu Dandan , Wang Zhenzhen
Published: September 2024

Objective: To investigate and analyze the relationship between bullying, academic emotion, and teacher support in the nursing education of undergraduate nursing students. Methods: A convenient sampling method was adopted by conducting a questionnaire survey on undergraduate nursing students of a university from October 2022 to December 2022. Spearman’s correlation was used to analyze the relationship between bullying, academic emotions, and teacher support of nursing students, with a significance level of α = 0.05. Results: The total score for educational bullying was 12.51 ± 8.71, the total academic emotional score was 284.25 ± 34.69, and the total teacher support score was 80.76 ± 14.39. A negative correlation was found between nursing students’ bullying and teacher support, s = -0.20, P < 0.01, while a positive correlation was observed between academic emotion and teacher support, s = 0.21, P < 0.01. Additionally, bullying in nursing education was positively correlated with academic emotion, s = 0.25, P < 0.01. Conclusion: The academic emotion and teacher support of nursing students are at a moderate level. Part of the challenges in nursing survival is due to bullying in nursing education. Nursing educators should prioritize the stable development of nursing staff.
A Study on the Integration of Hainan Culture into College English Teaching Strategies
Authors: Yao Xiaochao
Published: September 2024

This study aims to explore the teaching strategies for integrating Hainan culture into college English courses and their impact on students’ learning outcomes. Drawing on relevant statements on cultural confidence, the research employs multiple methods, including questionnaires, in-depth interviews, classroom observations, and performance analysis, to systematically analyze the application effects of Hainan cultural elements in English teaching and student feedback. A survey of 200 students from a university in Hainan revealed that 90% of the students support the integration of Hainan culture into English teaching, 85% believe that this teaching method enhances their learning interest, and 80% think it helps improve cultural awareness. In-depth interview results show that both students and teachers agree that integrating culture into teaching not only improves English proficiency but also enhances cultural pride. Classroom observations indicate that students in the experimental class have significantly higher participation and interaction frequencies compared to the control class. Performance analysis shows that the English scores of students in the experimental class increased by 15%, significantly higher than the 5% increase in the control class. Comprehensive analysis results demonstrate the effectiveness of integrating Hainan culture into college English teaching. It is suggested that future teaching further enrich cultural content, innovate teaching methods, strengthen teacher training, improve evaluation mechanisms, promote interdisciplinary cooperation, and utilize external cultural resources to enhance students’ cross-cultural communication skills and overall competence.
Effect of PKD1L1 Mutation on its Interaction with PKD2 to Cause Situs Inversus Totalis
Authors: Haroon Fatima , Khan Salma Saeed , Ullah Assad
Published: September 2024

Situs inversus totalis (SIT) is a rare homozygous recessive disease caused by the mutation in PKD1L1, which is required for normal interaction with PKD2 and leads to different complications such as respiratory disorders, brain disorders and even obesity. The present study was designed to find out the mutational effect on the binding of PKD2 with mutated PKD1L1, which leads to SIT. The three-dimensional (3D) structure of wild type and mutated PKD1L1 was predicted with > 90% confidence using different online tools. The different online tools that were employed were SWISS-MODEL, Phyre2 (normal & intensive) and i-TASSER. To compute the physiochemical properties of PKD1L1 (wild & mutated) and PKD2 in silico approaches were employed using the ExPASy ProtParam tool. Physicochemical properties such as molecular weight, isoelectric point, the total number of negatively and positively charged residues, extinction coefficient, half-life, instability and aliphatic index, grand average of hydropathicity, and amino acid percentage were calculated. A lot of variability was observed in these parameters among PKD1L1 and PKD2, which accounted for diversification in their functional properties. The theoretical pI points showed that PKD1L1 (whole) is more basic with 6.64 pI compared to its first chain TOPO_DOM (amino acids from 1–1748) has a pI of 5.62 which means it is basic while PKD2 have the lowest pI point of 5.34. Docking was performed using the PatchDock and ClusPro online tools.

It is one of the main component of system suitability testing in a chromatographic system. The column efficiency can be assessed by using various traditional methods and reproducible results can be evaluated using liquid chromatography We studied the column efficiency using RP-HPLC technique for pharmaceutical drug product Aceclofenac in a validated method. Two mobile phases combinations Acetonitrile: Methanol (80:20 v/v) and Acetonitrile: Methanol: Ammonia (225:50:1 v/v) were compared on C-8 Lichrospher RP-HPLC column for Aceclofenac and three tablet samples (30 ppm). The height equivalent to theoretical plate (HETP) referred as direct measure of column efficiency produced efficient results (530-545 and 190-230) for respective mobile phases. The lower HEPT is an indication of efficient elution in second mobile phase. The change in polarity as per pKa of the analyte may enhance elution and resolution. helpful in method development for pharmaceutical and forensic drug analysis using liquid chromatography.

Authors: KUMAR JITENDRA , Singh Sonwani Nagendra , Ateriya Navneet
Published: September 2024

Death by Café' coronary syndrome is very rarely seen and at the same time challenging to interpret at the autopsy. We highlight the importance of autopsy in such cases and solve Café coronary at autopsy.

Café coronary syndrome was first reported as sudden collapse at restaurants while dining. Death was attributed to neurogenic cardiac arrest due to food in the upper airway and reflex vagal inhibition. Many of those individuals had consumed large amounts of alcohol before the incident. We present a series of three cases of sudden death by Café coronary in which food accidentally lodged in upper airways and collapsed suddenly without showing signs of asphyxia. Different risk factors were observed in all cases, including obesity as one of the associated risk factors for such incidence.

This paper underlines the significance of detailed autopsy and reliable history given by the witnesses related to death occurring by Café coronary syndrome.

Authors: Kang Jeongyoon , Kim Jieon , Park Jungheum , Lee Seokhee
Published: September 2024

The advancement of cloud-based data storage technology allows users to conveniently access and manage files using endpoint devices without being constrained by their environment. While cloud storage services have improved the efficiency of performing our daily tasks, they have also become a medium for criminals to distribute illegal materials. Services that support end-to-end encryption (E2EE), cannot decrypt data even when it's stored on their servers, attracting users who require high security. There are some existing studies related to cloud-based services using E2EE, but they only deal with local artifacts, which makes it difficult to analyze when local devices cannot be found or when there are changes to local artifacts. This study identifies the mechanisms by which MEGA, a cloud-based file hosting service, operates to obtain user authentication, explore metadata, and collect files while applying end-to-end encryption. Furthermore, we propose a forensic investigation methodology to explore various metadata and selectively acquire cloud resources relevant to an incident through an understanding of E2EE algorithms. Also, we apply MEGA to the existing framework to suggest improving the framework that encompasses E2EE cloud-based services. The findings of this study serve as a valuable reference for dealing with cloud-based services with E2EE from the perspectives of computer security and digital forensics.

This study received validation from 12 educational psychology experts regarding the program for reducing teacher stress. Additionally, ten middle school teachers in Y City, Gyeonggi Province, participated in the study, where the content of their writing was analyzed to explore the program's impact on stress management. The results revealed that reflective writing based on visual images is effective in helping teachers recognize and manage their emotions and problems, leading to an increase in positive emotional expression. Furthermore, offering the program through an online platform provided teachers with opportunities to manage their stress without being constrained by time or location. This study presents a new approach to managing teacher job stress and could serve as foundational data for developing programs applicable to various professions in the future.
Optimization of calculations in modeling the breaking of plasma oscillations
Authors: Chizhonkov E. V.
Published: September 2024

The proposed method of optimization of calculations is of a combined nature. First, using a piecewise uniform grid, a difference scheme of the second order of accuracy of the McCormack type is constructed, and then — to weaken the stability condition — an implicit version of the scheme is used, which even in the nonlinear case allows an iteration-free implementation. When constructing a grid, a preliminary study is required, which is based on the analytical properties of the solution of the differential problem. Based on the calculations carried out, it can be concluded that the potential reduction in the amount of calculations is dozens of times without a noticeable loss of accuracy.

The primary objective of this current study is to conduct a comprehensive analysis of the ways in which various leadership styles influence the overall organisational effectiveness of higher education institutions. Furthermore, the goal of the research is to determine whether demographic variables have an impact on the evaluation of organisational efficacy and the perceptions of leadership of individuals within these institutions. Data were meticulously collected from a sample of 215 teachers in Himachal Pradesh, India, who held a variety of positions at both private and public higher educational institutions. This was done in order to attain these objectives. The results of this study provide compelling insights: Initially, it is clear that demographic variables, at least to a certain extent, influence perceptions of organisational efficacy and leadership within higher education institutions. These variables include, but are not limited to, age, gender, educational background, and years of experience. Secondly, the research emphasizes a substantial correlation between the organisational efficacy of these institutions and the transactional style of leadership. In the context of higher education in Himachal Pradesh, transactional leadership is a significant influence on organisational efficacy, as it is defined by a focus on structured rewards and explicit communication of expectations. These results enhance comprehension of the manner in which demographic factors and leadership dynamics interact to influence the operational efficiency of educational institutions in this region.

Background: This study compares performance anxiety and aggression between female swimmers and female para-swimmers. It aims to identify significant differences and provide recommendations for enhanced psychological support for both groups.
Objective: To compare and analyse performance anxiety and aggression levels between para and able-bodied swimmers, identify key contributing factors, and develop recommendations for improved psychological support and coping strategies for both groups.
Method: This study involved a total of 50 national-level subjects, consisting of 25 female swimmers and 25 female para-swimmers, to identify previously unknown psychological drawbacks. All participants were aged between 18 and 30 years. Tests were administered to assess psychological variables including Aggression and Competitive State Anxiety as well as influencing factors in their sports careers.
Result: The analysis revealed that female swimmers had significantly higher levels of aggression (M = 80.04, SD = 14.72) and competitive state anxiety (M = 19.35, SD = 3.01) compared to female para-swimmers, who had lower scores in both areas (aggression: M = 72.04, SD = 13.77; anxiety: M = 17.08, SD = 5.91). T-tests showed significant differences in aggression (t = 2.02, p = 0.048) and anxiety (t = 2.99, p = 0.004) between the two groups, indicating that female swimmers experience higher levels of both psychological variables than female para-swimmers.
Conclusion: Female swimmers show significantly higher levels of aggression and competitive  state anxiety compared to female para-swimmers. These findings highlight the need for targeted psychological support to address these elevated levels and improve overall athlete well-being and performance.
