Authors: Chávez Vázquez Gustavo Esteban
Published: January 2025

The present work shares the scope that the didactic museography proposes in the perception of heritage through the construction of itinerant collections, with the aim of situating the expositions that are deduced from it for the presentation of samples that contribute to the approach of diverse knowledge topics, besides exposing the experience in the development of the project entitled "Migrants" memorandum of the Ibero-American high school of the State of Mexico. Within the experience in this school, we try to describe a school project that is based on the foundations of museography; In this way, establish an articulation between museum and school. The purpose of this experience allows us to see the ways in which the representation of heritage can become a didactic strategy in teaching-learning processes. Through the recovery of different museum projects immersed in the creation of exhibitions, exhibitions and exhibitions of a transdisciplinary nature, the aim is to establish a complementation that helps to glimpse the importance of itinerant collections and their educational extension; as well as, the different perceptions about the material and immaterial cultural heritage of a certain place.
Paraíso prohibido. Imágenes dialécticas en la construcción del Estado del Interior.
Authors: Londoño Fernando
Published: January 2025

The dominant state of the 20th century in Colombia was the result of the political process lived during the 19th century. This one sought to assimilate but to attenuate, the modern ideology that was taking place in the international context. In order to accomplish this, Colombian politicians developed a double speech about Colombian identity: a “modern” foreign policy and an internal policy with rural and semi feudal features. Artists and intellectual people, felt and represented in their works the consequences of this paradox.

Género y memoria en la Atenas arcaica y clásica
Authors: Sierra Rodríguez David
Published: January 2025

Este artículo aborda las principales líneas de evolución de los discursos y espacios de memoria atenienses desde una perspectiva de género y a través del análisis de fuentes textuales y arqueológicas. Se propone una visión de amplio alcance, ya que, desde el primer momento, la memoria griega se construye sobre la división de género y sobre formas desiguales de recordar y percibir el propio recuerdo. En Atenas, la configuración de una nueva identidad política a partir de Solón, muy exclusiva de los varones, es causa y a la vez consecuencia de nuevas dinámicas de memoria en los discursos y los paisajes. Esta nueva memoria oficial necesita controlar y apropiarse de representaciones femeninas en su propio beneficio. Sin embargo, no puede ignorarlas ni evitar el surgimiento y existencia diaria de memorias más libres.

Hablar sobre la población mexicana y querer generalizarla se ha vuelto una tarea compleja, en virtud de que, si se quiere hablar sobre “la población mexicana” y pensar que los mexicanos son morenos, o son mestizos, o blancos, es tener una postura de carencia cultural de la diversidad genética y poblacional que existen, por ello resulta innecesario querer etiquetar a los mexicanos en un solo aspecto o característica. Dentro de este vasto país existimos personas de todo tipo.
En el sentido de la diversidad, no es de extrañarse que existan mexicanos afro, y es que basado en el último censo poblacional de INEGI (2020) “En 2020, a nivel nacional, dos de cada 100 personas se consideran afrodescendientes” (párr. 4), esto es alrededor de 2.5 millones de personas se auto perciben como afromexicanos, representando el casi el 2 % de la población total.

Published: January 2025

Los eventos adversos representan una de las principales causas de mortalidad a nivel mundial debido a las numerosas complicaciones derivadas de una atención de salud insegura. Por ello, el objetivo del presente trabajo fue describir el comportamiento de los eventos adversos en pacientes con COVID-19 hospitalizados en unidades críticas y su impacto en la morbimortalidad. Se llevó a cabo una investigación cualitativa y descriptiva, basada en una revisión bibliográfica de fuentes secundarias obtenidas de bases de datos indexadas como Scopus, Scielo, Pubmed y Google Académico, con una muestra de 50 artículos analizados de manera inductiva. Para la selección de los artículos se tomaron como criterio de inclusión a las publicaciones científicas en idioma inglés, español y portugués, publicados desde febrero 2020 hasta abril 2023. Por otra parte, fueron excluidos artículos secundarios como carta al autor, comentarios, casos, editoriales, tesis doctorales y maestrías. Los resultados mostraron que el desconocimiento y la falta de competencias entre los profesionales de salud han comprometido la seguridad de los pacientes. Esto, sumado al impacto de la pandemia de COVID-19 en la fragmentación de los sistemas de salud, ha llevado a prácticas inseguras y dilemas éticos, especialmente en personas mayores con comorbilidades. Se pudo concluir que los eventos adversos pueden tener un impacto significativo en los pacientes, afectando su salud, bienestar psicológico, calidad de vida y confianza en el sistema de atención médica, además de aumentar los costos, la estancia hospitalaria y la tasa de morbimortalidad.

This paper examines the economic impact of the COVID-19 pandemic on private dental practices in Bucharest, Romania, focusing on the influence of practice size and employee numbers. A comparative analysis was conducted across three years: 2019, 2020, and 2021, utilizing data sourced from the Romanian Finance Ministry. In 2019, there were 1,735 active dental practices, but this number declined to 1,704 in 2020 and further to 1,644 in 2021. Key financial indicators (KFIs) such as turnover, profit, revenue, expenses, debts, and employee numbers were analyzed. The findings revealed a significant decrease in turnover and revenue in 2020 compared to 2019 (p 0.001), with larger practices (those employing more than three individuals) facing a greater economic burden than smaller ones. However, in 2021, larger practices demonstrated a significant recovery, showing higher increases in turnover, profit, and revenue compared to the smaller ones (p 0.001). This research shows how important adaptable workforce management is in a dental practice for staying profitable during economic crises. This paper suggests that dental practices should create strategies to improve their resilience against future crises based on these findings.

The Department of Dental Radiology (UMF Carol Davila) implemented an online experimental method to examine the radiological knowledge of the students, adapted to the context of the SARS COV 19 pandemic. The study focused mainly on topics less assimilated by the students in the online teaching period. It was also performed a comparative analysis of the students’ results with the summative final examination (online grid test) based on the official university’s protocol of examination and secondly with the equivalent examination from the pre-pandemic period (face-to- face examination). The errors made by the students were linked to: periodontal diagnosis (34%), edentulous diagnosis ( 22%) dental diagnosis (19 %); bone diagnoses ( 12%), soft tissue diagnosis ( 1%) . From the dental diagnosis mistakes, the most common (40%) where related to systematization of answers. From the periodontal diagnosis, the errors of pointing the correct diagnosis ( 36%) where similar as percentage with errors of expressing correctly the diagnosis ( 32%). The Gaussian distribution of the scores from the experimental test were similar as shape and values comparing with the final grades obtained with the online grid test but verry different from the scores from the last pre-pandemic assessment( non- Gaussian distribution). Conclusion: the experimental method was reliable, appearing better than the previous face-to-face examination. It also showed the topics that needed to be better explained for an optimized learning.

Published: January 2025

Aim of the study This systematic review aimed to centralize the information regarding the effect of the orthodontic treatment with clear aligners (CAT) on the masticatory muscles activity, functional or parafunctional, by objective recording means of surface electromyography (sEMG). Materials and methods : An electronic search was performed until June 2024 using the following search strategy :(((orthodontic OR clear OR removable) AND (aligner*)) OR Invisalign) AND (Bruxism OR (parafunctional masticatory forces) OR (masticatory muscle activity) OR clenching) AND (EMG OR Electromyography). Time restrictions for the search were established between 2000-2024.
Results 640 studies were computed. Using the PRISMA method, 38 duplicates were found and removed to obtain 602 studies to be screened by title and abstract. 9 studies were eligible to be reviewed. Conclusions CAT does not influence muscle activity. Most of the data available is about the response of the masseter muscle but there is no clear evidence that this is the most affected muscle by bruxism.

Published: January 2025

This review aims to summarize the literature on classic and advanced surgical management strategies for tibial plateau fractures. The primary objective in treating these fractures is to restore joint functionality and ensure favorable short- and long-term outcomes. Effective surgical management minimizes the risk of joint instability, enhances long-term prognosis, and maintains the patient's quality of life. Most orthopedic surgeons adopt a staged treatment strategy, involving initial stabilization followed by definitive surgical fixation, respecting soft tissue conditions, achieving precise anatomical reduction, ensuring stable fixation, and promoting early rehabilitation. Surgical techniques include open approaches with arthrotomy for articular surface reconstruction and fixation using plates and screws, as well as minimally invasive approaches such as arthroscopy or percutaneous fixation with screws or external fixators. Modern osteosynthesis techniques—plates, screws, external fixators, and rotating hinges—have become the standard of care, except in cases of minimal displacement. These approaches collectively aim to optimize patient recovery and joint functionality.

This retrospective study evaluated the impact of orthodontic treatment on endodontically treated teeth. 32 teeth from 25 patients were analyzed, focusing on CBCT evaluations. All endodontic treatments utilized EDTA and 5.25% NaOCl in conjunction with Er:YAG laser-activated irrigation. Post-treatment assessment revealed that 21 teeth (66%) had root canal fillings of correspondent length, while 10 teeth (31%) were insufficient, and 1 tooth (3%) was uncertain. In terms of density and homogeneity, 25 teeth (78%) were classified as correspondent, 5 teeth (16%) as inadequate, and 2 teeth (6%) as uncertain. The periapical bone destruction probability index (PRI) demonstrated a significant increase in periapical destruction following orthodontic treatment. Specifically, the odds ratios for bone destruction were 1.67 (90% CI: 1.16–2.49, P=0.008) for present versus absent and 1.77 (90% CI: 1.11–2.85, P=0.031) for present versus uncertain. The proportion of teeth without periapical destruction decreased from 15 (14.9%) during treatment to 14 (23.9%) post-treatment. These findings highlight the critical relationship between endodontic quality and treatment outcomes, emphasizing the need for meticulous endodontics during orthodontic therapies.

Published: January 2025

Aim: Our study aimed to identify the procedural errors of endodontic treatment and to establish the prevalence of apical periodontitis (AP) in root canal treated teeth by means of cone-beam computed tomography (CBCT). Material and method: There were a total of 604 treated permanent teeth. We looked for apical radiolucency and errors, such as: incomplete filling, missed canals, instrument fracture, perforation, overfilling, non-homogeneous fillings. Results. The overall prevalence of AP was 58.6%. The most frequent error was incomplete filling (42.88%), followed by low-density fillings (34.1%), missed canals (26.32%), overfilling (15.72), perforations (3.8%), fractured instruments (2.64%). Risk factors identified that were significantly associated with AP were: incomplete filling more than 2 mm, missed canals, perforations, non-homogeneous fillings, fractured instruments, tooth type (posterior) and cast posts. Conclusions. Prevalence of AP in endodontically treated teeth in this study was high. Poor quality root canal obturations were associated with post-treatment apical disease. CBCT is a precise imaging diagnostic tool and accurately highlights the technical parameters of the canal obturation, but also the presence of AP even in the early stages.

Aim of the study: With chronic kidney disease (CKD) projected to be the fifth leading cause of death by 2040, this study investigates oral health and the relationship between salivary and renal function in pre-dialysis CKD patients. Material and methods: A cross-sectional survey of 51 pre-dialysis patients at a nephrology center in Bucharest collected socio-demographic data and assessed salivary function, oral health, and renal function. Measurements included saliva quality, pH, buffering capacity, calcium, phosphate, IL-6, TNF-α, and albumin, while oral health was evaluated using the DMFT index, OHI-S, GI, CAL, and assessments of periodontal disease. Renal function was assessed through serum creatinine, urea, and estimated glomerular filtration rate (eGFR). Results: Impaired saliva quantity was noted in 65% of participants (n=34), with elevated salivary calcium in 43.8% (n=22) and below-reference levels of IL-6 and TNF-α. Dental health was poor, reflected by a high DMFT score, fair oral hygiene, and moderate to severe gingival inflammation in 43.1% (n=22). Moderate or severe periodontal disease was observed in 45.1% (19.6% moderate, 25.5% severe), while median CAL and PD indicated moderate periodontal health. Renal function was compromised, with median eGFR placing 90.2% (n=46) in CKD stages 3–5. Significant associations included filled teeth and stimulated saliva (p 0.01), missing teeth and salivary calcium (p 0.05), filled teeth and IL-6 (p 0.05), and lower creatinine levels correlating with higher DMFT (p 0.01). Conclusions: This study underscores the significant link between pre-dialysis CKD and oral health, revealing higher prevalence of dental caries, periodontal disease, and salivary alterations in this group. Early intervention in oral health management is essential for improving outcomes and slowing disease progression.

Published: January 2025

Biodegradable magnesium (Mg), calcium (Ca), and strontium (Sr) alloys have garnered significant interest in regenerative medicine due to their unique mechanical properties, biocompatibility, and controlled degradation combination. These materials are particularly promising for temporary implants, such as orthopedic screws, plates, and cardiovascular stents, as they eliminate the need for secondary surgical removal and provide osteogenic benefits through the release of bioactive ions. Despite their potential, the clinical implementation of Mg-Ca-Sr alloys faces several challenges, including precise control of degradation rates to match tissue healing, optimization of biocompatibility to prevent inflammatory responses, and addressing the complexities of industrial production for consistent quality and performance. Future research directions focus on employing advanced technologies like nano-engineering and 3D printing to tailor the properties of these alloys for specific applications. Long-term in vivo studies are critical for understanding their behavior in biological environments while combining these alloys with ceramics or polymers could create hybrid materials with enhanced mechanical strength and degradation control. Additionally, artificial intelligence offers opportunities to optimize material design and predict clinical outcomes. Mg-Ca-Sr alloys are promising to transform the landscape of biodegradable implants, address current limitations, and improve patient outcomes through innovative materials and fabrication techniques.
Impact of biomechanical properties of tongue muscles on accuracy of English vowel pronunciation
Authors: Zhang Ping , Chen Xiaoguang
Published: January 2025

Pronunciation is a complex physiological process. Traditional research usually uses static pronunciation tests and fails to observe the dynamic changes of tongue muscles during pronunciation. This paper aims to comprehensively analyze the structure and function of tongue muscles and their role in English vowel pronunciation from the perspective of tongue muscle biomechanics, and provide a systematic framework for understanding. This paper designs multiple pronunciation tasks to evaluate participants’ pronunciation accuracy and dynamic changes of tongue muscles. Through multi-modal technology, dynamic images and electromyographic signals of the tongue are synchronously acquired to analyze the precise relationship between tongue movement and muscle activity in the pronunciation of English vowels. A tongue biomechanical model is constructed based on finite element analysis and Hill model to precisely simulate the mechanical response of tongue muscle activity and tongue position changes during pronunciation. The experimental results show that there is a significant negative correlation between electromyographic activity and pronunciation quality. The closer the correlation coefficient is to −1, the higher the consistency. The tongue is positioned higher and forward during pronunciation, making it easier to control, so that the pronunciation can be more accurate with less deviation. The greater the movement and flexibility of the tongue, the better it is able to form clear vowel pronunciations. In short, the tongue muscles achieve precise control of tongue position through the coordinated action of internal and external muscles during vowel pronunciation, which is beneficial to improving pronunciation accuracy.

PENDAMPINGAN PERUMUSAN REKOMENDASI KEBIJAKAN PENATAAN PARKIR DI KOTA TANJUNGPINANG
Authors: Wira Winata , Arianto Bismar , Adhayanto Oksep , Husna Asmaul
Published: January 2025

Kebijakan perparkiran di Kota Tanjungpinang merupakan salah satu isu penting dalam pembangunan daerah, mengingat masalah serupa terjadi di banyak wilayah perkotaan lainnya. Kondisi ini menjadi perhatian khususnya bagi pengambil kebijakan yaitu Pemerintah Kota Tanjungpinang dan publik sebagai pengguna layanan parkir yang memiliki harapan terhadap kenyamanan dan keteraturan dari sistem perparkiran yang efektif. Peningkatan jumlah kendaraan bermotor di Kota Tanjungpinang sejalan dengan pertumbuhan sosial ekonomi masyarakat namun di lain pihak, ketersediaan ruang publik tetap terbatas karena pertambahannya yang relatif stagnan. Bagi pemerintah daerah, sistem perparkiran memiliki dua fungsi utama: sebagai instrumen fiskal untuk meningkatkan pendapatan daerah dan pemenuhan tanggung jawab pelayanan publik dalam penyediaan fasilitas parkir yang memadai. Kenyataannya, penyelenggaraan parkir yang sebagian besar dilakukan oleh pihak ketiga, seperti badan usaha, belum sepenuhnya optimal dalam memenuhi kewajiban sebagai pembayar pajak daerah. Akibatnya, peningkatan volume parkir tidak sebanding dengan kontribusinya terhadap pendapatan daerah. Dalam konteks ini, tim pengabdian masyarakat dari Universitas Maritim Raja Ali Haji (UMRAH) Tanjungpinang, yang terdiri dari akademisi lintas program studi, telah melakukan pendampingan untuk mengidentifikasi permasalahan yang ada dan merumuskan langkah-langkah strategis untuk mengatasinya. Kegiatan ini berlangsung selama sekitar tiga bulan, dari Mei hingga Agustus 2023, dan menghasilkan sejumlah rekomendasi yang diharapkan dapat ditindaklanjuti oleh Pemerintah Kota Tanjungpinang.

La propagación mediante cultivo in vitro representa una opción eficiente para la producción a gran escala de plantas libres de patógenos, manteniendo intactas las características genéticas del material vegetal donante. El presente estudio tuvo como objetivo establecer el medio de cultivo apto para la propagación de tomate (Solanum lycopersicum L.) mediante explantes apicales. Para este ensayo se procedió a evaluar el efecto de diferentes concentraciones de inositol (100, 300 y 500 mg/L), utilizando el medio basal Murashige y Skoog (MS). Se analizaron variables como el porcentaje de contaminación y viabilidad, altura de planta, número de hojas y longitud de raíz. Los resultados mostraron que el tratamiento T1 (100 mg/L de inositol) presentó la mayor altura de planta (6.54 cm) y un menor porcentaje de contaminación, mientras que el tratamiento T3 (500 mg/L) registró una respuesta intermedia en la mayoría de las variables evaluadas. Por otro lado, la longitud de raíz y el número de hojas no mostraron diferencias estadísticas significativas entre los tratamientos, aunque T1 tuvo una ligera tendencia a mejores resultados. Los hallazgos destacan la importancia de optimizar la concentración de inositol en el medio de cultivo para maximizar el desarrollo inicial de los explantes y reducir la incidencia de contaminación. Este trabajo contribuye al perfeccionamiento de protocolos de cultivo in vitro en tomate, sentando las bases para investigaciones futuras sobre el efecto de aditivos secundarios en el cultivo de tejidos.

n el municipio de Calpulalpan Tlaxcala, se encuentran dos microrregiones principales con problemas de erosión en el suelo por la pérdida de la cubierta vegetal, por lo que el establecimiento de Sistemas Agroforestales (SAF) representan una propuesta apropiada para la conservación del suelo en dichas microrregiones, las cuales son: San José y Coecillos. El objetivo de esta investigación fue analizar las acciones realizadas, las limitantes y alternativas para los Sistemas Agroforestales establecidos por los productores en las microrregiones de San José y Coecillos del ejido de San Antonio Calpulalpan, Tlaxcala. Utilizando la metodología de análisis y diagnóstico de los sistemas de producción en las dos microrregiones, mediante la aplicación de un cuestionario semiestructurado (en entrevista presencial) con 50 ejidatarios, obteniendo algunas variables como: edad, escolaridad, actividad principal, superficie con sistemas agroforestales, tiempo de establecimiento, características, ventajas y limitantes de los sistemas agroforestales, entre otros aspectos.

Dentro de los resultados obtenidos se obtuvo que los principales factores de fomento del establecimiento de sistemas agroforestales son la recuperación de la fertilidad de los suelos agrícolas, el valor biocultural y económico de las especie vegetales perennes, como el maguey pulquero (Agave salmiana), y el conocimiento tácito de los ejidatarios para el diseño y plantación de sistemas agroforestales. En contraparte, los resultados obtenidos evidencian que los principales factores que limitan el establecimiento, son la falta de asesoría técnica especializada y la baja disponibilidad de recursos económicos de los ejidatarios. Una de las conclusiones más destacadas es que las características sociales y agrícolas de ambas microrregiones, requieren de una política regional de fomento agroforestal donde los cereales, especialmente la cebada, se vean como parte de un todo llamado sistema agroforestal, cuya función no solo es mitigar el deterioro ambiental, sino también el conservar tradiciones y costumbres de la población

Изучено влияние параметров процесса микронизации на активность уреазы и изменение влажности соевой рушанки при подготовке ее к экструдированию. Установлены оптимальные параметры процесса микронизации, показано, что наибольшее влияние на эти показатели оказывает продолжительность второго этапа облучения.

The influence of the parameters of the micronization process on the activity of urease and the change in the moisture content of soybean flour during its preparation for extrusion was studied. The optimal parameters of the micronization process have been established, and it has been shown that the duration of the second stage of irradiation has the greatest influence on these parameters.
Cyber threat intelligence in practice: Implications of the blurred lines between public and private intelligence activity
Authors: Ashdown Neil , Martin Keith
Published: January 2025

Intelligence is recognised as crucial for strengthening organisational security, particularly in the cyber domain. Companies have developed their own intelligence capabilities to address this requirement. Cyber threat intelligence (CTI) has historically been understood as a primarily technical, politically neutral practice. In contrast, this paper argues that CTI is socio-technical, collaborative and political. Interviews with industry and government practitioners were undertaken to better understand how CTI practitioners viewed their work. The findings underlined the importance of personal trusted relationships and collaboration. Companies were found to be working closely with government, often in ad hoc and informal ways. Moreover, the public and private sector were viewed as having different, complementary forms of visibility into the cyber domain. Together, this has contributed to a blurring of the lines between public and private organisations. These findings suggest that companies should promote trusted personal relationships through a combination of formal and less formal methods. At the same time, companies should be alive to the risks inherent in conducting intelligence activities in ‘operational intimacy’ with state actors, particularly in a period of increasing geopolitical competition and conflict.
Differences between traditional network security and security in the cloud

Published: January 2025

Serverless computing is transforming cloud application development by removing the need for infrastructure management, enabling developers to focus on writing and deploying code. This cloud-computing execution model offers significant advantages in cost-effectiveness, scalability and operational efficiency, with cloud providers dynamically managing server allocation, scaling and maintenance. Prominent serverless computing services include Amazon Web Services (AWS) Lambda, Azure Functions and Google Cloud Functions, facilitating faster development cycles and improving application performance. Security remains a critical concern as the serverless computing market grows. This paper focuses on AWS Cloud security, exploring the differences between traditional network security and cloud security and emphasising the challenges unique to the cloud environment. It advocates for a defence in depth strategy, which employs multiple layers of security to protect cloud infrastructure. The paper underscores the AWS shared responsibility model, which clearly outlines the security responsibilities of both AWS and its customers. It also explores the AWS Well-Architected Framework, which provides best practices for constructing secure, reliable and efficient cloud workloads. Additionally, it discusses the significance of a well-designed landing zone in AWS for managing multi-account environments and ensuring security through multilayered protection mechanisms, including identity and access management (IAM) policies, resource policies, data encryption and network security. In conclusion, the adoption of comprehensive security strategies, such as defence in depth and the utilisation of AWS tools and best practices, is not just beneficial but crucial for enterprises to secure their serverless computing environments. These measures play a pivotal role in mitigating risks, enhancing security postures and fully leveraging the benefits of serverless computing, thereby driving digital transformation initiatives.
Data minimisation: A crucial pillar of cyber security
Authors: Luehr Paul , Reilly Brandon
Published: January 2025

As data security threats mount, businesses should not lose sight of a fundamental but powerful tool to mitigate risk: data minimisation. Businesses across industries should recognise the potentially devastating security, operational and compliance risks that arise from keeping old and unreliable data. Helpfully, the latest generation of privacy laws are increasingly mandating data minimisation, purpose limitation and other measures designed to protect individual privacy. Such measures have the additional benefit of shrinking the surface area for cyberattacks and other threats to the confidentiality, integrity and availability of data. Leveraging new laws and technology, companies should maximise the value of their information by focusing on sound data governance, ensuring that it is not just an ‘IT issue’. Then businesses should use new tools to map their data and determine its age and sensitivity and start minimising their retention and use of data that no longer meets current business or compliance requirements. Businesses can use a variety of techniques to slim their data profile, eg destruction, de-identification, tighter retention policies, privacy-enhancing technology. In the end, these minimisation actions will be well worth the effort. Businesses will unlock their data’s true value, increase their productivity and avoid the serious privacy and information security risks that come from housing data they no longer need.
Investigating the Correlation Between Influencing Factors Affecting Students’ Interest in Learning and Academic Performance in Mathematics
Authors: Marbella Mary Bernadine , Cruz Yvonne
Published: January 2025

This study aimed to determine the factors influencing pupils’ interest in learning Mathematics and differences in pupils’ mathematics performance when grouped according to their subject of interest and subject with difficulty. The respondents of the study were the 183 randomly selected Grade VI pupils of the 10 Elementary Schools in Cluster 9 of the Division of Guihulngan City for the school year 2023-2024. The researcher utilized the descriptive correlational survey method and a validated researcher-made questionnaire. The instrument underwent reliability testing using the test-retest method with a gap of two weeks from its initial administration. Results of the test revealed coefficient stability of 0.95 (teaching pedagogy), 0.93 (utilization of learning resources), 0.91 (assessment strategies), and 0.92 (performance task). The researcher adhered to and observed the ethical guidelines outlined by Foundation University’s Ethics Committee. Consultation was pursued to ensure the research issue becomes clearly sound, significant, and ethically proper. The following statistical tools were used: percentage and frequency, weighted mean, mean, Kruskall-Wallis H-test, and t-test. The study then revealed that the following factors have a very high influence on pupils’ interest in learning Mathematics: (a) Teaching Pedagogy, (b) Utilization of Learning Resources, (c) Assessment Strategies, and (d) Performance Task. Data revealed that pupils’ performance in Mathematics based on grades is within the very satisfactory level. Moreover, a significant relationship exists between the earlier factors that influenced pupils’ interest in learning Mathematics and their Mathematics performance. Results further showed substantial differences in pupils’ Mathematics performance when grouped according to their subject of interest and subject with difficulty. At the same time, pupils’ demographic profiles cannot account for the differences in pupils’ Mathematics performance.
