Objective: This study aimed to identify and measure the awareness of anterior cruciate ligament (ACL) prevention programs among professional and semi-professional soccer players in the Qassim region.
Methods: This cross-sectional study was conducted by interviewing the professional players in the Qassim region and using an online questionnaire for the semi-professional players. The questionnaire and the interview were designed to assess awareness and interest in preventive training programs (PTPs).
Results: In total, 740 soccer players were surveyed. The predominant age bracket was 21-25 years, comprising 45.8% of the participants. A notable 28.8% participated in tournaments. Awareness of ACL preventive programs was observed among 12.2% of the players. In a multivariate regression analysis, factors such as prior ACL injury history, education concerning ACL injuries, and ongoing engagement in ACL PTPs emerged as significant independent predictors influencing awareness of ACL PTPs.
Conclusion: Athletes demonstrated limited awareness of ACL preventive programs. Factors such as prior ACL injury history, education about ACL injuries, and active participation in ACL injury prevention programs were identified as significant drivers for increased awareness of ACL PTPs. Moreover, the involvement of physical therapists and coaches played an important role in enhancing athletes' understanding of ACL PTP concepts.

Authors: Albuagmi Shoag , Altoukhi Khaled , Albaqmi Omar , Alarawaji Fatma
Published: November 2024

Background: Ectopic pancreas is defined as a pancreatic tissue lacking vascular or anatomical continuity with the main body of the pancreas. The majority of cases are symptomatic; however, they can present with bleeding or luminal obstruction. Herein, we present a case that had ectopic pancreatic tissue in the mesentery of proximal jejunum mimicking gastrointestinal stromal tumor.
Case Presentation: We present a case of a 24-year-old Saudi female, married who presented to the emergency room because of lower central abdominal pain radiating to the flanks for 9 days with on-and-off fever, 1 day diarrhea, and urinary symptoms. She was conscious, coherent, afebrile, and ambulatory with vital signs in the Emergency room revealed an oral temperature of 36.5°C, heart rate of 81 bpm, respiratory rate of 18 per minute, BP of 121/75 mmHg, and SpO2 of 99%. Abdominal examination revealed soft and lax tenderness in the lower central abdomen and left flanks.
Conclusion: Ectopic pancreatitis should be taken into account in a patient who has chronic abdominal pain with a normal native pancreas according to imaging results. Small intestinal tumors, whether detected on imaging investigations or accidentally found after surgery conducted for another reason, should be diagnosed with ectopic pancreas in mind.

Objective: This study aimed to assess awareness and knowledge of septic arthritis among the general population in Alahsa, Saudi Arabia.
Methods: A cross-sectional study was conducted among 391 participants aged 18-87 years in Alahsa, Saudi Arabia. Data were collected through an online questionnaire that assessed awareness of septic arthritis' symptoms, causes, risk factors, and sources of information. The survey was distributed via social media, and informed consent was obtained.
Results: The study found that 34.3% of participants had heard of septic arthritis, with joint pain being the most recognized symptom (68.6%). However, awareness of other symptoms like joint swelling (58.9%), warmth (51.2%), and fever (30.6%) was low. Nearly half of the participants correctly identified bacteria as the leading cause (48.6%), though misconceptions about viral and fungal causes were common. Weakened immunity (41.2%), and joint conditions (38.4%) were the most frequently identified risk factors. Higher education levels (chi-square = 13.661, p-value = 0.018) and employment in the health sector (F = 31.674, p-value < 0.001) were significantly associated with greater awareness, while no significant association was found between awareness and gender.
Conclusion: The study highlighted gaps in awareness and knowledge of septic arthritis in Alahsa. Public health efforts should focus on educating the population, especially through healthcare professionals and online platforms, to promote early diagnosis and treatment. Further research is needed to assess the effectiveness of educational campaigns.
Intergenerational Healing within Waterscapes:
Authors: Rodriguez Milena Renee
Published: November 2024

Since time immemorial, humans have had a flowing communication with Water and have been connected to Water in infinite ways through ritual, celebration, storytelling, and contemplative practices (Leonard et al., 2023). We are Water. This essential truth of our interconnected existence has been denied by past and present interrelated systems of violence, such as colonialism, patriarchy, and pollution, which have affected us and our planet (Ansloos, 2023). In this article, I analyze the films Estiu 1993 (2017) and Whale Rider (2003), their girl child protagonists Frida and Pai, and illustrate how young girls find a spiritual connection to themselves, their departed loved ones, and the world through a spiritual connection with the Waterscapes they have access to. I also highlight Indigenous perspectives about intergenerational healing through embodied Water practices and rituals. with the beyond-human world (Rodriguez, 2024). I offer suggestions on approaching the films pedagogically, emphasizing the potential to integrate anti-oppression and eco-justice discussions within multigenerational and culturally safe educational environments.

Authors: Medellf Gladys , Tascón Esther Cilla
Published: November 2024

Se realizó un experimento de campo para evaluar el efecto de un diseño educativo sobre salud reproductiva y sexualidad, en 423 estudiantes de primer semestre, de la Universidad del Valle, Cali, Colombia, dividido en 2 grupos: experimental y control. El diseño se desarrolló en forma de taller, con los siguientes temas: riesgo reproductivo (embarazo, aborto, enfermedades de transmisión sexual), órganos de la reproducción, métodos anticonceptivos y actitudes hacia la sexualidad. Al relacionar el nivel de conocimiento sobre sexualidad y salud reproductiva con las variables estrato socioeconómico, sexo, facultad, tipo de colegio de estudios secundarios, educación y profesión de los padres, se encontraron mayores conocintlentos en los alwnnos de la Facultad de Salud, de estrato medio, que procedían de colegios privados no mixtos y cuyos padres tenían educación secundarla, universitaria y/o de profesiones técnicas o universitarias. Los hallazgos indicaron que las diferencias en conocintlentos y actitudes, antes del diseño educativo, entre los grupos control y experimental no fueron significativas. Al comparar los promedios de conocimientos y actitudes del grupo experimental, antes y después del diseño educativo, se observó un incremento estadísticamente significativo. Los resultados de este estudio permiten corroborar la importancia de establecer programas de educación sexual para los adolescentes y jóvenes a nivel de instituciones educativas con el fin de disminuir los riegos a que están expuestos en salud reproductiva y sexualidad.

Published: November 2024

Introdução: A perda de um filho é uma experiência devastadora, principalmente no período perinatal, com especificidades que a tornam única. Há um importante impacto financeiro no sistema de saúde, com aumento do risco de surgimento de luto complicado e transtornos mentais graves, incluindo tentativas de autoextermínio. Apesar dos avanços na compreensão do enlutamento perinatal, os pais relatam se sentirem silenciados e estigmatizados no processo. Método: Revisão narrativa sobre luto perinatal e seu impacto na saúde mental dos pais, a partir de busca dos principais estudos nas plataformas PubMed, MEDLINE, Embase e Cochrane com os descritores “perinatal grief”, “perinatal loss”, “miscarriage”, "stillbirth'', “TOPFA”, “neonatal death” e “anxiety”, ”depression” ou “PTSD”. Resultados: O luto perinatal é privado de direitos sociais, com ausência de suporte do parceiro e da rede de apoio social como principais fatores de risco para o desenvolvimento de transtornos mentais. Possui como características principais a perda do próprio senso de identidade, do papel parental e do senso de ser um ente feminino reprodutor. Apresenta sentimentos e pensamentos ruminativos disfuncionais relacionados a culpa e autopiedade, medo, decepção, raiva, fracasso e de inveja de outras mulheres poderem gerar um filho, além da percepção de ter sido traída pelo seu próprio corpo. A prevalência de transtornos mentais varia amplamente na literatura entre 8.6% e 49%, sendo os principais: depressão, ansiedade e transtorno de estresse pós-traumático. Conclusão: O luto perinatal representa uma experiência devastadora e única, com impactos significativos na saúde mental dos pais. A falta de suporte social, a perda de identidade e os riscos de transtornos mentais ressaltam a necessidade urgente de uma abordagem mais capacitada por parte dos profissionais de saúde mental. É fundamental que haja um acolhimento e tratamento adequados, visando mitigar os impactos psicossociais e econômicos desse processo desafiador para essas famílias.
A similar feature point matching method for aerial electric power tower images based on a one-ring neighborhood of vertices
Authors: Chen Keyu , Guo Jufu , Wang Weijun , Lei Bo , Huang Hui , Luo Lijing
Published: November 2024

Due to the susceptibility of images to various factors such as scale changes, imaging conditions, and image noise, traditional feature point matching methods are difficult to achieve ideal matching accuracy, leading to many challenges in the automatic analysis and processing of power tower images. To improve the matching accuracy of similar feature points in aerial images of electric power tower, this study proposes a method for matching similar feature points in aerial images of electric power tower based on a vertex ring neighborhood, addressing the problem of large matching errors caused by factors such as scale and imaging conditions. This method first adopts the feature point extraction technique of electric power tower image based on decomposition and filtering, and constructs the Laplacian pyramid of the original image. Subsequently, filter banks are used to decompose the pyramid image in different directions, extract local extremum points as candidate feature point sets, and merge them to obtain the final feature point set. On this basis, taking into account the spatial relationships and geometric characteristics around the feature points, a texture mapping algorithm based on vertex ring neighborhood and patch classification is applied to construct a vertex ring neighborhood structure and extract geometrically representative electric power tower features. Finally, by using a texture feature point matching method based on the principle of similarity, the similarity between the real-time image and the reference image features is calculated for matching, and combined with the Babbitt coefficient to remove mismatched feature points, accurate matching of similar feature points in aerial electric power tower images is achieved. The experimental results show that this method has a mean square error of less than 0.1 Pixel in matching similar texture feature points of aerial power tower images under various working conditions, significantly improving the matching accuracy and providing an effective tool for automatic analysis and processing of power tower images.

Published: November 2024

В статье приведены результаты экспериментов по воспроизведению процесса прерывистого скольжения по модельному разлому и инициирования подвижки борта разлома флюидными и электрическими воздействиями. Отличительной особенностью использованной экспериментальной установки является протяженный подвижный блок, позволяющий существенно увеличить площадь межблочного контакта, заполненного сухим мелкозернистым песком. Это позволило исследовать пространственную картину развития зон активного деформирования контактной зоны посредством решения задачи локации источников акустической эмиссии. Отдельное внимание уделено изучению отклика контактной зоны на инжекцию в неё воды и прямое воздействие электрического тока. В результате проведенных экспериментальных исследований определены пространственно-временные закономерности отклика модельного разлома на увеличение сдвиговой нагрузки и флюидные и электрические воздействия. Показано, что воздействие электрического тока вызывает рост акустико-эмиссионной активности во всей области между электродами за исключением области активизации эмиссии на этапе инжекции воды. Установлено, что электрическое воздействие может приводить к инициированию динамической подвижки с активизацией пространственных областей, проявленных на предыдущих этапах воздействия.

This paper presents the results of experiments to reproduce the stick-slip process along a model fault and to induce fault edge movement by fluid and electrical effects. A special feature of the experimental setup used is an extended movable block, which allows to significantly increase the area of the interblock contact filled with dry fine-grained sand. This makes it possible to study the spatial pattern of the development of active deformation zones of the contact zone by solving the problem of locating acoustic emission sources. Particular attention has been paid to the study of the response of the contact zone to the injection of water into it and to the direct application of electric current. As a result of the experimental studies, spatiotemporal patterns of the response of the model fault to an increase in shear load and fluid and electrical effects have been determined. It is shown that the effect of electric current causes an increase in acoustic emission activity throughout the area between the electrodes, except for the emission activation area at the water injection stage. It was found that the electrical action can lead to the initiation of dynamic motion with the activation of spatial areas manifested in previous action stages.

В предлагаемой статье сделана попытка проследить эволюцию некоторых базовых положений модели геофизической среды М.А. Садовского в работах сотрудников ИДГ РАН. Богатый экспериментальный материал, накопленный на протяжении многих лет участия в испытаниях ядерного оружия, послужил фундаментом для развития динамики деформирования массивов горных пород на разном иерархическом уровне. Показано, что многие современные подходы и результаты последних лет в том или ином виде были предсказаны в работах М.А. Садовского. Продемонстрирована ключевая роль разломных зон в эволюции деформационных процессов в земной коре. Развитие нового научного направления Геомеханика разломов открывает новые возможности в решении фундаментальных и прикладных задач физики твердой Земли.

The article attempts to trace the evolution of some basic provisions of the model of the geophysical medium by M.A. Sadovsky in the works of the employees of the IDG RAS. Rich experimental material accumulated over many years of participating in nuclear weapons tests served as a foundation for developing the dynamics of rock mass deformation at different hierarchicallevels. It is shown that many modern approaches and current results anyway were predicted in the works of M.A. Sadovsky. The key role of fault zones in the evolution of deformation processes in the Earthʼs crust is demonstrated. The development of a new scientific school «Geomechanics of Faults» opens up new possibilities in solving fundamental and applied problems in the physics of the solid Earth.

Published: November 2024

The rapid digital transformation driven by Artificial Intelligence (AI) is reshaping innovation and operational efficiency across industries. As autonomous AI systems are becoming prevalent, they significantly influence traditional business models, societal norms, and legal frameworks. AI technologies are evolving beyond mere tools to become independent economic agents capable of generating assets, making decisions, commercializing products and services, and being accountable for their actions. This evolution requires a reassessment of traditional concepts of corporate and moral personhood, particularly as AI-driven businesses need to operate inside conventional legal frameworks. This paper explores the rise of entirely AI-driven entities with fully autonomous decision-making processes, advocating for the legal status of artificial personhood. It underscores the need for an ethical and regulatory framework to ensure these entities will proliferate and operate for human progress with integrity and responsibility.

The ambiphilic reactivity of alkyl sulfonyl fluorides in the stereoselective synthesis of diverse cyclopropanes from ole-fins under palladium(II) catalysis is presented. The sulfonyl fluoride functionality serves as both an acidifying group and an internal oxidant within the ambiphile, enabling the successive carbopalladation and oxidative addition steps in the catalytic cycle, respectively. The transformation grants access to cis-substituted cyclopropanes and exhibits broad compatibility with various alkyl sulfonyl fluorides, including those bearing –CN, –CO2R, isoxazolyl, pyrazolyl, and aryl groups. With internal alkene substrates, 1,2-3-trisubstituted cyclopropanes that are otherwise challenging to synthesize are formed in good to moderate yield and predictable diastereoselectivity. Detailed mechanistic insights from reaction progress kinetic analysis (RPKA) and density functional theory (DFT) calculations reveal that the SN2-type C–SO2F oxidative addition is the turnover-limiting and diastereoselectivity-determining step.

Published: November 2024

Objective: To determine the effect of Public Private Partnership (PPP) financing structure on the completion of geothermal energy development projects in Kenya.
 
Theoretical Framework: The study used agency and public choice theories to analyze the dynamics between PPP financing structure and completion of geothermal energy development projects.
 
Methodology: A cross-sectional census survey in Kenya surveyed 48 geothermal energy development projects, collecting quantitative data through structured questionnaires and qualitative insights from industry regulators, financiers, and practitioners. A combination of descriptive, correlation, and linear regression statistical models were applied. Multiple diagnostics tests and data triangulation were performed.
 
Results and Discussion: The study results provide strong statistical evidence depicting a positive relationship between PPP financing structure and the completion of geothermal energy development projects in Kenya. The findings suggest that as the level of PPP involvement increases, so does the likelihood of faster project completion. The study also reveals that a balanced PPP financing structure has a substantial effect on the completion of geothermal energy development projects. The analysis demonstrates that a hybrid PPP financing structure comprising recommended proportions of private and government equity, commercial and concessional loans, hybrid finance, and grants significantly affects project completion outcomes.
 
Research Implications: The study emphasizes the significance of a structured PPP financing model, comprising private and government equity, concessional and commercial loans, hybrid finance, and mixed grants, in mitigating inherent PPP risks for enhanced project completion outcomes. In addition, effective government support measures and robust delivery capability of developers jointly influence the two variables in a significant manner.
 
Originality/Value: This study uniquely analyzes the influence of PPP financing structure on the completion of geothermal energy development projects in Kenya, integrating quantitative and qualitative data for a comprehensive perspective, thus offering essential insights for stakeholders.

Authors: Oyasor Emmanuel Imuede , Gbadebo Adedeji Daniel
Published: November 2024

Objective: This article develops and analyses the framework in promoting sustainable job satisfaction based on experience of a Canadian firm, the National Best Financial Network (NBFN).
 
Method: The paper applies the Five C’s (Company, Customers, Competitors, Collaborator and Climate/Context) and the PEST (political, economic, socio-cultural and technological) analysis to evaluate the situations for the strategic decision and attainment of the objectives.
 
Result and Discussion: The paper reveals that the industry remains an attractive one due to the ability to compete moderately with a similar product and the low switching costs of buyers.
 
Implications: The implication is that growth potential and demand for the product/service is expected to increase, and the threat of substitute products/services are weak. While threats from new entrants is low, existing companies have the advantage of existing market share and can take active efforts to retain it.
 
Originality/Value: The note provides information that identifies the issues affecting the growth and development of the firm, and the financial industry in Canada.
 
Recommendations: We recommend regulatory policies that allow for ease of entry along with the ability to quickly assimilate into the market with existing technology.

Published: November 2024

Purpose: The major objectives of the study were to assess the classroom management practices of the teachers, to assess the critical thinking skills of the students and to measure the effect of teachers’ classroom management practices on the development of students’ critical thinking skills.
Design/Methodology/Approach: The research approach was quantitative and correlational research was used. The population of the research was based on 7294 faculty members serving in HEC recognized universities of Islamabad. Sample of 447 teachers was selected by using stratified-sampling technique. Researcher used classroom management practices scale based on 45 items and critical thinking skills assessment scale based on 47 items.
Findings: The data revealed that the classroom management had no effect on Critical Thinking Development. Teacher’s cohesiveness had 0.1% negative effect, teacher’s support had no effect, teacher’s involvement had also no effect, teacher’s skill related to investigation had 0.1% effect, task orientation had 0.2% effect, teacher’s co-operation had 0.2% negative effect and teacher’s equity had 0.2% positive on student’s critical thinking development. However none of the above mentioned effect was statistically significant. Teachers need to learn how to manage positive learning environment. For this purpose, teachers need to use regular feedback, appreciations, and interactive classroom discussions and peer learning methods.

Authors: Usenko O. Y. , Fedorov D. O. , Hrynenko O. V , Ostapyshen O. M , Pidopryhora O. O.
Published: November 2024

Objective. To evaluate the safety and early results of laparoscopic extended liver resection in case of focal liver pathology by retrospective comparison with the relevant parameters of a similar open intervention.
Materials and methods. The study involved 162 patients who were divided into two groups: Group 1 – 50 patients who underwent laparoscopic extended liver resection, and Group 2 – 112 patients who underwent open extended liver resection. The groups were compared by age structure, sex, body mass index, type of pathology (benign/malignant), as well as by characteristics of surgical intervention and postoperative period. Statistical analysis included a t–test for independent samples, Pearson's chi–square test, and other appropriate methods with the calculation of the confidence level p (parametric criterion). The difference in indicators was considered statistically significant at p < 0.05.
Results. Laparoscopic osshire  for liver resection was longer (p = 0.0012), but was associated with a lower level of pain according to the visual analog scale (p = 0.02) and fewer bed days to discharge (p = 0.0007) than a similar open intervention. There was no statistically significant difference between the groups in terms of age structure, body mass index, number of liver tumors, blood loss, complication rate, and degree of ischemic liver damage.
Conclusions. Laparoscopic extended liver resection is a less invasive method than open liver resection, and patients recover faster after it, although its duration is longer. At the same time, laparoscopic and open intervention had a similar incidence of complications, which indicates acceptable safety and high clinical efficacy of the laparoscopic approach in the treatment of patients with liver disease.
