The main findings of the study are that there is a correlation between attitudes and concerns regarding inclusion and teacher self-efficacy and that there are factors such as employment, experience and education that have an influence on attitudes towards inclusion.
Reform dynamiReform Dynamics and the Professionalisation of Principals in Sweden and Finland. A Study of Articles in Union Journals Since the 1990’scs and the professionalization of principals in the North of Europe since the 1990’s.
Authors: Troedson Nicklas , Wermke Wieland
Published: October 2024

This article analyses union journals in Sweden and Finland since 1990. In doing so, the article recognises the journals as principals’ collective professional voice regarding major education reform dynamics. Our findings suggest that principals in both Nordic countries, as collective actors, have clearly influenced reforms of the school system significantly. The unions serve as a strong voice with major influence in both professional and reform ambitions. However, the main arguments for the respective professional projects were similar, although professional ambitions were different in both cases: discretion for more educational leadership, without explaining what educational leadership means in detail.

Published: October 2024

This study aimed to identify selected catabolic genes in two indigenous hydrocarbon-degrading bacteria involved in the biodegradation of used engine lubricant-contaminated soil. Used engine lubricant-contaminated and uncontaminated soil samples were collected, and their physicochemical characteristics were evaluated. The results indicated that water holding capacity, potassium, nitrogen, and phosphate were higher in used lubricant-uncontaminated soil than in used lubricant-contaminated soil but vice versa for pH, total carbon, cation exchange, organic carbon, nickel, and lead levels. Culturable heterotrophic and hydrocarbon-utilizing bacterial counts were carried out on both Nutrient agar and Mineral Salt Medium (MSM) amended with used engine lubricant. The counts for heterotrophic bacteria (3.8×108±0.21 cfu/gm) were higher than that of hydrocarbon-utilizing bacteria (2.2×108±0.15 cfu/gm). All isolated bacteria (16) underwent screening for hydrocarbon degradation potential. Lysinibacillus odysseyi and Bacillus sp (in: firmicutes) emerged as the best oil degraders. Further screening of the chromosomal and plasmid DNA of the two bacteria was done to determine the presence and location of some selected catabolic genes (NidA, AlkB, NahH, NahAC, and Alma). The presence of Alkane monooxygenase (AlkB) and Naphthalene dioxygenase (NahAC) genes was confirmed in both isolates, while Pyrene dioxygenase (NidA) was confirmed in Bacillus sp. (in: firmicutes) only. The location of AlkB was confirmed to be both plasmid and chromosome, while NidA and NahAC genes were confirmed to be the plasmid. In conclusion, the soil contaminated with used engine lubricant contained indigenous bacteria, Lysinibacillus odysseyi, and Bacillus sp. (in: firmicutes), the two bacteria with the highest degradation potential, contained catabolic genes, monooxygenase (AlkB), NidA, and dioxygenase (NahAC). Therefore, they are effectively used as engine lubricant degraders, and the possibility of horizontal gene transfer can be used in important industrial applications and is recommended for the bioremediation of petroleum compounds.
The Selfish Suicide in Jay Asher’s Thirteen Reasons Why from an Existentialism Perspective
Authors: Thamer Hasan Hasan
Published: October 2024

The suicide of the character Hannah Baker in Thirteen Reasons Why (2007) by Jay Asher (1975) functions as a central element that prompts an examination of existentialist motifs. With an emphasis on personal accountability, autonomy, and the quest for significance, this abstract analyzes the concept of “The Selfish Suicide” through an existentialist lens. Existentialism asserts that people possess the agency to mold their own lives by using the decisions they make. Hannah’s choice to terminate her life is interpreted as a demonstration of her agency and a reaction to the suffering she endures. The suicide she commits may be perceived as a last-ditch effort to regain authority over her life and alleviate the anguish that she is enduring. Moreover, the novel emphasizes the concept of genuineness, compelling readers to confront the practicalities of their lives and conduct themselves in alignment with their personal principles. Hannah’s act of suicide may be interpreted as a repudiation of the duplicity and lack of authenticity that she observes in others. Through her audio recordings, she exposes the conduct and attitudes of individuals responsible for her anguish to hold them accountable for their decisions. Nevertheless, the novel also explores the repercussions of Hannah’s suicide on those who remain, thereby prompting inquiries into the significance of personal choices and the obligation that people have towards one another. In conclusion, Thirteen Reasons Why offers an existentialist analysis of “The Selfish Suicide” that is intricate and multifaceted. The text stimulates readers to contemplate the following themes: personal accountability, autonomy in decision-making, and the quest for significance. Serving as a poignant illustration of the importance of empathy, compassion, and understanding in our interpersonal exchanges, the novel underscores the criticality of contemplating the repercussions of our decisions on those in our immediate vicinity.
Innovativeness of the European economies in the context of the modified European Innovation Scoreboard
Authors: Nawrocki Tomasz L. , Jonek-Kowalska Izabela
Published: October 2024

Research background: Innovation is an important determinant of economic development, and its importance is growing with the advancement of digitization and the development of the Fourth Industrial Revolution. In turn, the assessment of the innovativeness of a country’s economy affects its investment attractiveness and international image.
Purpose of this study: Given the factors presented above, the main aim of this study is to explore and compare the innovativeness of European economies in the context of the modified European Innovation Scoreboard.
Methods: To achieve this goal, the authors propose two key modifications of the existing innovation assessment methodology contained in the European Innovation Scoreboard. The first concerns the principles of the normalization of assessment indicators and aims to eliminate extreme assessment values. The second proposes to remove the indicators which are difficult to measure, subjective, and not always useful: (1) those related to sustainable development (resource productivity; emissions of fine particulates; and environment-related technologies) and (2) those that take into account only small and medium-sized enterprises (SMEs introducing product innovations; SMEs introducing business process innovations; and innovative SMEs collaborating with others).
Findings & value added: An alternative approach to assessing the innovativeness of the analyzed countries — as proposed by the authors — resulted in changes in the ranking of countries in relation to the European Innovation Scoreboard, but the changes were not significant. The major changes concerned Serbia (down four places), Belgium (down two places), Hungary (up three places), and Poland (up two places). In addition, five countries moved up one place in the ranking (the UK, the Netherlands, Luxembourg, Estonia, Slovenia, Spain, and Slovakia), and five lost one place in the ranking (Norway, Italy, Portugal, Greece, and Croatia). Thirteen countries had no changes. The obtained results allowed us to conclude that the countries with the best and the worst innovativeness maintained the assessment level regardless of changes in the methodology of its implementation. The objectification of rules had the strongest impact on the countries in the middle of the ranking. This study draws attention to the problem of the subjectivity of the innovation rankings. It has also been documented that modifying the selection of evaluation criteria may change the final position in the ranking, which, in the case of emerging and developing economies, may affect investor assessment and economic growth opportunities. Such considerations are important because they are outside the often uncritical mainstream approach to the assessment of the innovativeness of economies. The conclusions imply the need for a multisource analysis of innovation and a critical look at the proposed methodologies.

Currently, the aquaculture industry is challenged with disease outbreaks and pathogen infections with using intensive aquaculture production, to mitigate these challenges. Using phytogenic natural compounds as dietary curcumin nanoparticles that have been extensively applied in aquafeeds to enhance the performance, antioxidant activity, and innate immunity of several fish species. The present study investigates the response of white-leg shrimps (Litopenaeus vannamei) challenged with Fusarium solani fed on dietary curcumin nanoparticles (C-NPs) on growth, digestive enzymes activity, antioxidant enzymes activity, and their humoral immune responses. White-leg shrimps, L. vannamei (3.56±0.02g) were raised in triplicate groups for 56 days on a diet contained 39% protein and 11% lipid and contained 5 concentrations of C-NPs (0 as the control, 15, 30, 45, and 60 mg/kg). The pathogen, F. solani confronted the shrimps after the feeding trial. The findings showed that the performance parameters FBW, WG, SGR and FCR increased significantly (P≤0.05) by 19.5%, 34.82%, 18.47%, 18.33% and 3.07% with increasing the concentrations of dietary C-NPs. The amount of 45 mg/kg C-NPs in shrimp feed serving as an optimum dosage. The control diets had the highest cumulative mortality of white-leg prawns when they were exposed to the pathogen (70.00%), followed by T1 (55.00%) and T2 (45.00%), while T3 and T4 recorded the lowest cumulative mortality rates (35.00%). The intestinal layers (mucosa) of infected shrimps treated by different concentration of C-NPs were significantly improved by 15%. Therefore, the current study recommended using dietary C-NPs to enhance the white-leg shrimp's functionality, digestive and antioxident enzymes activities and immune system response.
O conceito de consciência e o ensino de História

Published: October 2024

Este artigo discute o conceito de consciência, realizando um debate com o pensamento idealista, especificamente aquele ligado ao ensino de História. Importante se faz sistematizar essa categoria, na sua relação com a Pedagogia histórico-crítica, por ser uma filosofia de ensino mais adequada, se pensada do ponto de vista do materialismo histórico e dialético. O artigo debate com a Didática e com a Teoria de História, de Jörn Rusen, procurando demonstrar que, vendo a categoria de consciência a partir da Pedagogia histórico-crítica, o conceito de Consciência Histórica, de Rüsen mostra-se problemático. Defende-se que esse conceito não nos permite pensar as categorias de dialética, práxis e outras, importantes na análise e na síntese marxista, relacionadas ao ensino de História.

Authors: Azizati Zidni , Rohmatun Nisa Umi , Khofya Haqiqi Arghob
Published: October 2024

Biodegradable foam can be used as an alternative packaging which is safe for health and environment. The raw material used to produce biofoam is starch. Taro consist of 67.42% starch. Contrarily, biofoam produced from starch has fragile mechanical properties. The addition of chitosan aims to improve the mechanical properties of biodegradable foam. Beside that, Chitosan is expected to reduce water absorption and increase tensile strength of biodegradable foam without reducing degradability. Biodegradable foam was synthesized by three steps, first step was isolation of starch from taro, second step was synthesis of biodegradable foam from taro starch-chitosan which used various concentration of chitosan to study the effect of chitosan addition for mechanical properties of biodegradable foam. Various concentration of chitosan was 0%, 1%, 2%, 3%, and 4% (w/w). Third step was characterization of biodegradable foam.  The Analysis of biodegradable foam was carried out included FTIR functional group, mechanical properties, biodegradability and water absorption. The result showed that the best tensile strength test was 1% chitosan addition with a value of 3.75 MPa; based on water absorption test, the optimum sample was 4% chitosan addition with a value of 11.66%. The results of the functional group analysis of FTIR biodegradable foam contained of C=O (amide), CN, NH and OH groups which indicated the existence of chitosan in the sample.

Published: October 2024

Lithium battery as one of the energy storage has two important elements, namely electrodes and electrolyte. Electrolyte is a part of the battery element that has undergone many developments. In this study, the manufacture of electrolytes in the form of Solid Polymer Electrolyte (SPE) was carried out by utilizing the abundant availability of nata de coco. The nanofibrous cellulose structure in Bacterial Cellulose (BC) nata de coco has the advantages of good porosity, flexibility in surface functionality, compact porous structure that provides abundant ion pathways and hetero atoms (oxygen atoms) with free electron pairs that facilitate ionic conduction. The SPE synthesis process was carried out by varying the soaking time of nata de coco in ethanol, namely 1, 2 and 3 days to determine the structure with optimal results. FTIR characterization results show the synthesis of cellulose nanofiber has the same groups as commercial cellulose groups in the form of O-H, C-H, C=O and C-O. CV characterization results show the SPE electrolyte has good redox properties, especially in the 2-day variation with the highest specific capacitance. The EIS test showed the lowest resistance in the 1-day variation sample with a conductivity of 0.017 ohm-1.

Published: October 2024

Bacterial cellulose (BC) is a natural polymer with good mechanical properties and hydrophilicity. Polyvinyl alcohol (PVA) is a synthetic polymer widely used in medicine. Both have been researched for their potential in drug release and acceptance. This study aims to determine the role of BC and PVA as drug release matrices for tetracycline hydrochloride (TCH), with additional fillers such as graphite (G) and TiO2. The results showed that the composites with BC matrix had lower mechanical properties than those with PVA matrix, with tensile strength values of 6.4075 and 17.446 MPa, respectively. However, the BC matrix was superior in porosity and swelling ability. The drug release testing of TCH from the composites showed that the appropriate model to describe drug release in BC matrix composites was in zero order, while the PVA matrix was in first order. The antibacterial activity of the composites on both matrices was tested against Staphylococcus aureus. The results indicate that both composites have potential applications in promising biomedical fields.

Degradable plastics may be employed as a substitute for conventional plastics in various commercial applications. Plastics made from starch and PVA-g-MAH are biodegradable. This research uses sago and jackfruit starch, a maleic anhydride compatibilizer, and PVA to make degradable plastics stronger. The research method consists of several stages, making sago starch and jackfruit seed starch, preparing degradable plastic synthesis, and testing the resulting degradable plastic. The test of mechanical characteristics of degradable plastics carried out is the tensile strength test of 4.41 Mpa - 6.02 MPa on sago starch-based degradable plastic with PVA-g-MAH, while the tensile strength of 6.86 - 8.43 MPa on jackfruit seed starch-based degradable plastic with PVA-g-MAH. The test shows that the compound is hydrophilic, meaning it binds to water and is easily degraded by soil. The DSC thermogram shows that the plastic samples degrade when heated, both thermogram peaks occur which indicate physical changes. The swelling value obtained in sago starch degradable plastic with PVA-g-MAH is (28.14-72.17%) while in jackfruit seed starch degradable plastic, the swelling obtained ranges from (25.91-84.72%) showing a good result. Sago starch and jackfruit seed starch degradable plastics degraded in 6-18 days using PVA-g-MAH. Sago starch and jackfruit seed starch-based plastics using PVA-g-MA meet the ASTM 6400 standard for biodegradable plastics. The plastic should be able to biodegrade up to 60% within six months or 90% within one year.

Kokosan (Lansium domesticum cv Kokossan) is one of the Meliaceae family plants known to produce various compounds with various activities. The Meliaceae family is known to have fruit seeds with a bitter taste that can be utilized as an antifeedant in insects. However, research on the bioactivity and content of secondary metabolites in the roots and bark of kokosan as termiticides against subterranean termites has never been reported. This study aims to determine the content of secondary metabolite compounds and test the anti-termite activity of extracts and fractions of kokosan root and stem bark against Coptotermes curvignathus Holmgren termites. Root and stem bark powder were macerated separately using methanol solvent and then fractionated to obtain n-hexane, dichloromethane, ethyl acetate, and methanol fractions (residue). Each extract and fraction was fed to termites through cellulose paper at a concentration of 5% for 3 days. Based on the results of phytochemical tests on extracts and fractions from the roots and bark of kokosan, it is known to contain alkaloid, flavonoid, terpenoid, and phenolic compound groups. The results of the anti-termite activity test are based on the percentage mortality value obtained by the methanol extract of the most active root with a value of 97.2% and paper weight loss of only 6.92%. In the ethyl acetate fraction of the roots, mortality was 84.4% and paper weight loss was 2.38%, and the n-hexane fraction of the stem bark showed mortality of 87.6% and paper weight loss of 2.20%. The kokosan root obtained has the most active activity against Coptotermes curvignathus Holmgren.

The phenomenon of old-age pensioners reentering the workforce is neither new nor unique and has been well-reported in several published literature. However, there are remaining challenges to this group of job seekers whose needs have yet to be well-documented from employer’s perspectives, especially regarding decent work, legal landscape, and organizational culture. Our study seeks to provide a better understanding of the underlying causes of these and to help policymakers introduce social protection policies to create a more welcoming and supportive environment for older workers. The study used a case study from service companies in Thailand that participated in the Thai government’s campaign on promoting older employment. Data was collected from interviews with top managers of the human resources department, and that information was analyzed by thematic analysis. Key findings highlighted that the supportive mechanisms for matching decent work, a room for integrating legal framework, and a culture that values inclusivity and fair treatment of all workers, regardless of age, can enhance the social protection system for older workers. The establishment of a modern database of older workers’ skills, which ensures easy accessibility to both employers and older workers, the establishment of a task force specific for monitoring laws and regulations concerning older employment, and the development of effective measures against workplace discrimination are recommended as effective interventions for social protection.

Published: October 2024

Background and Objective

In Kenya, the leading cause of maternal deaths is obstetric hemorrhage (39.5%), with postpartum hemorrhage (PPH) accounting for 50% with quality of uterotonics as one of the biggest challenges. The World Health Organization (WHO) in 2018 included heat-stable carbetocin (HSC) for the prevention of PPH in settings where the quality of oxytocin cannot be guaranteed. Maintenance of the cold chain for uterotonics is a challenge. HSC does not require refrigeration, reducing pressure on the fragile cold chain infrastructure. The main objective was to understand PPH prevention knowledge, experience, and perspectives, including uterotonic use, by policymakers and healthcare providers (HCPs) in the public health sector in ten counties in Kenya. HCP knowledge, perception, and experience were assessed after the HSC introduction.

Methods

The mixed methods study was implemented in 39 secondary and tertiary public hospitals from ten counties. Quantitative interviews targeting 171 HCPs at baseline and end-line were collected using REDCap software (v5.26.4) and analyzed using Stata version 17. Qualitative data was collected from 19 policymakers at the national, county, sub county, and health facility levels and analyzed using NVIVO 12.

Results

At the end line, 98.8% had administered HSC for the prevention of PPH, while 96.5% of the HCPs were aware that their facilities had protocols/guidelines in place on the use of HSC. To enhance awareness of WHO recommendations on the use of HSC among HCPs, a top-down approach was used. Over 90% of HCPs agreed that HSC was easy to administer and distinguish from other uterotonics. Policymakers agreed that there was value in the HSC introduction in the public health sector that experiences cold chain challenges and recommended budgetary allocation.

Conclusion and Global Health Implications

The findings demonstrate that HCP’s knowledge, perception, and experience coupled with the policymaker’s perspective is the key to the introduction of HSC in the public sector. Policymakers find value in introducing HSC as it alleviates challenges with the fragile cold chain systems. This study contributes to the global body of knowledge on the introduction of lifesaving commodities, which is anticipated to potentially improve PPH prevention and management, and hence reduce maternal mortality.
Prevalence of HLA-B*27 in the North Indian population: A single-center study
Authors: Mishra Vikash Chandra , Chandra Dinesh , Raina Anoushka , Pandey Avdhesh , Raina Vimarsh
Published: October 2024

Objectives:

Ankylosing spondylitis (AS) is a type of spondylitis in which the spine and other joints are largely affected. A strong association of HLA-B*27 with AS has been observed. However, the exact mechanism underlying this association and the pathogenesis of the disease remains unclear. As the diversity of HLA varies among populations, our objective was to investigate the prevalence of HLA-B*27 and its allelic variants in the North Indian population.

Materials and Methods:

The data of 7451 individuals were analyzed for the study and all these samples have HLA typed by sequence-based typing from an American Society for Histocompatibility and Immunogenetics (ASHI)-accredited laboratory.

Results:

Among the studied population, 304 individuals (4.08%) were found to have HLA-B* 27 allele. The most frequent subtypes of HLA-B*27 observed in the North Indian population were HLA-B*27: 05 (21.71%) and HLA-B*27: 07 (16.28%). A total of 97 HLA-B genotypes were identified among studied population.

Conclusion:

The higher frequency of HLA-B*27:05 suggests an idea that the North Indian population may have a higher risk of AS.
What Do News Editorials Point to in the Framing of Nigerian National Security? Does Media Content Project Public Lens or Elites Power Hierarchies?
Authors: Muhammad Hamisu Sani
Published: October 2024

Growing cases of the role of media in national security tend to suggest that news is reflective of on the spot assessment. Yet, a corpus of literature shows that media influence is highly dominated by elites’ power, where media framing projects more of these power and influence. This paper therefore expounds on the extent to which news media editorials are reflective of public concerns or portray more of elites’ power. Succinctly, the aim is to explore what media editorials point to in the framing of national security issues. In view of the precarity of insecurity and mounting challenges of Nigeria’s national security, it is pertinent to unravel what constantly preoccupies media establishments, mostly, their editorial contents. And what trajectory and path do they tilt towards in the broader mediatization of the nation’s national issues occasioned by terrorism, militancy, banditry, kidnapping and other crimes. Overall, the paper provides a clue about how news editorials showcase and often pander to hierarchal power within Nigeria’s national security architecture.

Published: October 2024

The Belitong Geopark, located in Tanjungpandan is one of the geopark areas that has extraordinary natural potential. The sustainability of the Belitong Geopark has become a concern in recent years, with efforts to utilize the geopark's potential to support the economic growth of local communities that have not felt a significant economic impact. At the level of business communication studies, we see that there are barriers to effective communication with the resulting economic implications. The methods of this study are observation and literature review. The data that has been collected is then analyzed using Em Griffin's semiotic analysis. The results showed that the sustainability of the Belitung Geopark has a positive influence on the economic growth of the Tanjungpandan community. The increase in Tanjungpandan community income is driven by increased tourist visits to Geopark Belitung. The increase in employment of the Tanjungpandan community is driven by the increase in economic activities related to Belitung Geopark, such as tourism, trade, and services. The increased welfare of the Tanjungpandan community is driven by increased income and employment.

Published: October 2024

В работе исследуется тематическое многообразие междисциплинарного журнала. Цель исследований составляет построение графа знаний журнала для тематического представления и систематизации электронного архива и новых публикаций журнала. Исходные данные представляют собой статьи журнала, посвященные различным информационным и математическим технологиям в науке и управлении, то есть междисциплинарным исследованиям. Предлагается систематизация текстов с помощью методов векторного анализа. В процессе тематического анализа контента журнала предлагается разбиение на рубрики, устанавливаются связи рубрик и статей с соответствующими описаниями специальностей ВАК. Для анализа тематики используется разведочный анализ исходных текстов, далее применяются методы интеллектуального анализа данных. Результаты разбиения предоставляются экспертам журнала, после чего вырабатывается решение о формировании тематической рубрики и включении в нее специальностей ВАК. Статьи журнала интегрируются в семантическую библиотеку LibMeta, в силу чего онтология библиотеки достраивается и формируется онтология журнала, и на этой основе строится граф знаний журнала. Предлагается процедура навигации по контенту журнала с помощью графа знаний в семантической библиотеке LibMeta, которая может стать основой для информационного сопровождения научных исследований и создания цифрового ассистента в междисциплинарной предметной области. Примеры приведены для конкретного контента журнала, но предложенная технология может быть распространена на другие журналы, так как большинство журналов, относящихся к нескольким специальностям ВАК, естественным образом захватывают несколько дисциплин.

Сравнительный анализ систем управления научными рабочими процессами
Authors: Воскобойников М.Л. , Феоктистов А.Г.
Published: October 2024

Стремительное развитие параллельных и распределенных вычислительных систем, телекоммуникационных технологий и облачных платформ обеспечило возможность разработки и применения научных приложений с целью подготовки и проведения крупномасштабных экспериментов с большими массивами данных. Зачастую создаваемые приложения предполагают сложную схему решения задач, базирующуюся на интегрированном выполнении процессов передачи, обработки и анализа данных, ресурсоемких вычислений и принятия решений. При этом математическое и программное обеспечение приложений может реализовываться различными группами специалистов из разных организаций и ориентироваться на разнородные вычислительные ресурсы. Все это обусловливает необходимость использования развитых средств проектирования, реализации, развертывания и выполнения научных рабочих процессов в рамках единой распределенной вычислительной среды, интегрирующей в конечном счете алгоритмические знания, программно-аппаратное обеспечение, данные и разнообразные сервисы. В настоящее время в качестве таких средств, как правило, выступают системы управления рабочими процессами. В этой связи статья посвящена обсуждению текущего состояния известных систем управления рабочими процессами, а также рассмотрению проблем, связанных с научными рабочими процессами для различных вычислительных сред. Актуализируются проблемы разработки и применения подобных систем, которые в настоящее время не решены в полной мере. В частности, отмечается необходимость учета предметной специфики и обеспечения масштабирования вычислений, востребованность сервис-ориентированных приложений, эффективность эксплуатации гетерогенных сред, интегрирующих высокопроизводительные ресурсы пользователей, кластерные ресурсы центров коллективного пользования, Grid-систем и облачных платформ.
Модификация алгоритма минимальной степени для повышения эффективности вычислений при итерационном решении контактной задачи теории упругости методом конечных элементов
Authors: Дудаев М.А.
Published: October 2024

В статье предложена модификация классического алгоритма минимальной степени, предназначенного для упорядочения структуры глобальной матрицы коэффициентов системы линейных алгебраических уравнений метода конечных элементов, с целью повышения эффективности вычислительного алгоритма решения контактной задачи теории упругости при моделировании сопряжений деталей специальными контактными элементами сопряжения конструкций, применение которых обусловливает итерационное решение задачи с постепенным уточнением их состояния. Предложенная модификация реализована совместно с прямым методом Холецкого решения систем линейных алгебраических уравнений, вычислительная эффективность которого проявляется в наибольшей степени при решении систем с симметричной, положительно определенной матрицей коэффициентов, преимущественно имеющей в методе конечных элементов, разреженную структуру. Важной проблемой в методе Холецкого является заполнение «треугольного множителя» по сравнению с исходной матрицей в процессе разложения; уменьшение заполнения реализуется обычно с использованием известных эвристических алгоритмов, среди которых существенное распространение получил алгоритм минимальной степени. Модификация этого алгоритма, предложенная в работе, симметричной перестановкой строк и столбцов упорядочивает структуру исходной глобальной матрицы таким образом, что позволяет в процессе итерационного решения контактных задач теории упругости, проводить частичное разложение Холецкого на повторных итерациях с экономией времени расчета по сравнению с полным разложением. В работе показано, что структура матрицы, упорядоченная модифицированным алгоритмом, в целом, является менее предпочтительной, нежели при использовании классического алгоритма минимальной степени, так как претерпевает большее заполнение, однако, эффективность применения вычислительного алгоритма достигается с проведением повторных итераций при постепенном уточнении состояния контактных конечных элементов сопряжения конструкций. С использованием тестовой конечноэлементной модели сборного ротора, а также модели роторной системы реального авиационного газотурбинного двигателя, определены и показаны портреты исходных матриц и их треугольных множителей, проведены оценки количества арифметических операций и условного времени их выполнения при использовании классического и модифицированного алгоритма минимальной степени.

Authors: Yusuf Mohammad
Published: October 2024

This study aimed to validate variables impacting the prevalence of low back pain (LBP) in adolescents, focusing on gender, age, exercise, sedentary activities, and dietary factors. A cross-sectional study with random sampling was conducted among adolescents aged 9 to 19 years, using a modified questionnaire based on the Oswestry and Roland-Morris LBP and Disability questionnaires. The response rate was 81.9%, with the highest LBP prevalence (87.5%) in 18-year-olds. Overall, 93.5% of participants reported experiencing back pain, particularly among those not actively involved in sports; notably, 63% led a sedentary lifestyle.Of the subjects, 23.5% reported sleeping 6-8 hours, 29.5% went to the gym 2-3 days a week, and 30.6% consumed over 3 liters of water daily. Additionally, 45.2% maintained a diet rich in fruits and vegetables, while 26.1% consumed high-protein foods. A good breakfast routine was linked to significantly reduced LBP. Males (59.2%) reported higher LBP frequency than females. For relief, 48.8% of males sought medical help or took medication, while 34.4% relied on self-healing methods. The study underscored the associations between various factors and LBP in adolescents and school-age children.
