Authors:   Department of Foreign Languages and Literature, Addis Ababa University, Addis Ababa, Ethiopia, Shewangizaw Gashaw
Published: October 2024

This study examined the perceptions and practices of Federal Democratic Republic of Ethiopian Technical and Vocational Training Institute English teachers regarding student-centered learning. Interviews, focus group discussion and classroom observations revealed that while teachers generally hold positive attitudes towards student-centered approaches, their actual classroom practices often remain teacher-centered, heavily relying on textbooks and overlooking trainees' interests. The study identified several challenges, including a lack of practical skills for implementing student-centered methods, the constraints of summative assessments, and the need for continuous formative feedback. Addressing the gap between theory and practice will require professional development that integrates practical experience and the implementation of flexible policies that support teacher autonomy and curricula tailored to trainees' needs. These findings provide valuable insights into the contextual challenges faced by educators and suggest ways to better align teaching practices with the evolving demands of the workforce through ongoing improvement and localized responsiveness.

Authors: Rodríguez Gutiérrez Elvira , Sanz Mínguez Carlos
Published: October 2024

El conjunto de fíbulas recuperado en la Zona Arqueológica Pintia, situada entre los términos municipales de Padilla y Pesquera de Duero (Valladolid), supera los tres centenares y medio de ejemplares. De esta abultada colección, cincuenta y ocho piezas se pueden adscribir al modelo que E. Cuadrado denominó anular hispánica. El estudio del conjunto de anulares a través de una nueva propuesta tipológica, adaptada a este registro, nos puede servir de muestra extrapolable al mundo vacceo. Veremos, además, con mayor detenimiento, una particular variante, identificada por uno de nosotros como tipo 19 o de cabecera remachada, muy relacionada con piezas de orfebrería vaccea. La cifra de ejemplares del tipo 19 documentados en Pintia se ha visto duplicada en los últimos años, alcanzándose un total de nueve piezas, una de las cuales proporciona contexto preciso al haber sido recuperada en una tumba bien conservada; las posibles derivaciones que pudo tomar, basándonos en su peculiar sistema de montaje, puede situarla como el prototipo de otro modelo muy habitual en la meseta Norte: el 4g o de anillo grueso con cartela.

Authors: González Carlos Enrique
Published: October 2024

Los procesos de urbanización son una de las causas más ubicuas de pérdida de hábitat y fragmentación para la gran mayoría de la vida silvestre (Kattan, 2001). Aquí, modelamos la conectividad del hábitat para Glaucis hirsutus (colibrí pecho canela) en la ciudad Maracay en Venezuela y proponemos un corredor ecológico para conservar especies y hábitats altamente intervenidos entre el Parque Nacional Henri Pittier (PNHP) y el lago Valencia. Se seleccionó el mejor corredor utilizando Corridor Designer, basado en el mapa de idoneidad del hábitat a escala urbana de 1:5.000. El mosaico urbano de Girardot posee apenas el 13% de su superficie cubierta de bosques (11.280.132 m2), aunque la ciudad tiene un área importante con cobertura vegetal, estos parches "verdes" son en su mayoría adecuados para el movimiento y solo el 9% de ellos se consideran hábitat adecuado para G. hirsutus. El Calvario cerca de HPNP y la zona Sur de La Hamaca, en la zona de inundación del lago de Valencia, fueron seleccionados como núcleos de biodiversidad, siendo el corredor resultante la mejor ruta en términos de los criterios utilizados para G. hirsutus. El área total del corredor fue de 167,57 ha con una distancia lineal de 4.948 m, de los cuales el 17% son áreas adecuadas para el mantenimiento de las poblaciones de G. hirsutus y el 39% son adecuados para actividades reproductivas ocasionales. Por lo tanto, ambos necesitan ser protegidos y gestionados porque su extensión no es suficiente para actuar como áreas funcionales completas.

Les influences linguistiques sur le français : une perspective historique sur les emprunts germaniques et anglais
Authors: Asgarova Mahsati
Published: October 2024

Cette étude explore l'influence des emprunts linguistiques germaniques et anglais sur la langue française à travers une analyse diachronique. En se concentrant sur deux périodes principales de contact linguistique – les interactions avec les tribus germaniques au Moyen Âge et l'influence croissante de l'anglais à partir du XIXe siècle – l’article examine comment ces emprunts ont façonné le lexique français. Les emprunts germaniques, souvent complètement assimilés, ont marqué des domaines comme le militaire et la vie quotidienne, tandis que les emprunts anglais, plus récents, dominent les champs technologiques, économiques et culturels. L’étude montre que les emprunts germaniques se sont largement intégrés de manière phonétique et morphologique, tandis que les termes anglais conservent fréquemment leur "extranéité" linguistique. L’article propose également une réflexion sur l'impact de ces influences sur l'identité linguistique du français et ouvre des perspectives pour de futures recherches comparatives avec d'autres langues.

Fluency and Accuracy in The EFL Oral Expression and Comprehension Classroom
Authors: Cherrad Soraya
Published: October 2024

Speaking the target language is often defined by both EFL students and teachers as the principal objective of language learning. However, all foreign language teachers recognize that this is in fact, one of the most difficult skills to develop, given that the aim of speaking is hindered by many factors resulting in most being reticent and unforthcoming when asked to speak the target language. Thus, EFL students may have difficulty speaking fluent and accurate English. The present research took place at Djillali Liabes University of Sidi Bel Abbes (Algeria), exactly in English as a foreign language oral classes. It aims to analyze learners' attitudes in the EFL oral expression and comprehension classroom as well as to detect whether the focus on accuracy could hinder the practice of oral communication as well as cause problems in learning. Thus, both classroom observations and an interview were chosen as tools for data collection. Since the aim of language learning is to enhance EFL learners’ oral proficiency, this paper aims to highlight the value of both fluency and accuracy in the EFL oral expression classroom, for the latter to be reached.

The purpose of this article is to decipher and ponder the intricate dynamics of maintaining effective collaboration between school management and the community, outlining goals that must be formulated and shared by both parties. Such a partnership is relevant for the configuration of favorable and indispensable conditions for the creation of an autonomous and participatory school environment. Given the contemporary obstacles faced by public schools, the urgency of collective participation by all those involved in education, in synergy with the community, is clearly emerging to ensure commitment and excellence in the educational process. Thus, the objective of this study is to contribute to the formulation of robust methods that address these issues and, consequently, ensure a school where its main protagonists experience the pleasure of teaching and learning. The methodological approach adopted for this study was qualitative in nature, predominantly: 1) a bibliographical investigation (comprising books, journal articles and dissertations); 2) the practical experience accumulated in a public school, both as a student and as a teacher, revealing a significant lack of interest on the part of parents and/or guardians in relation to issues involving students and, specifically, the teaching-learning process. The research question that underpins this reflection is to understand which factors and/or aspects have a direct influence on the participation of the school community in the institution's activities. Based on this analysis, it was possible to conclude that democratic management and the integration of the school community are fundamental to ensuring educational quality, promoting the social, intellectual and professional development of students.

Authors:   Francisca Marta Nascimento de Oliveira Freitas, Machado Gezia Da Silva , Silva Iara Felix Da , Corrêa Raimunda Cardoso ,   Luiz Eduardo Rodrigues Lima
Published: October 2024

A insegurança alimentar e nutricional (ISAN) no Brasil representa um desafio contínuo, apesar de alguns avanços  recentes. Dados de 2023 mostram uma redução no percentual de lares afetados pela ISAN, que caiu de 36,7% para  27,6%. Contudo, cerca de 119 milhões de brasileiros ainda enfrentam ISAN moderada. Os principais fatores que  contribuem para a insegurança alimentar incluem desigualdade social, pobreza e vulnerabilidade econômica. A  concentração de renda e desigualdade estrutural limitam o acesso a alimentos adequados e nutritivos. Além disso,  a baixa escolaridade e desemprego agravam a situação, especialmente nas regiões Norte e Nordeste, onde a insegurança alimentar é mais prevalente. Embora políticas públicas e programas assistenciais tenham mostrado progresso, eles permanecem insuficientes para erradicar a insegurança alimentar. Desperdício de alimentos e ineficiência na distribuição também são desafios críticos que precisam ser abordados. A agricultura familiar, especialmente em comunidades quilombolas e áreas rurais, desempenha um papel importante na promoção da segurança alimentar através da produção local. As disparidades regionais continuam a impactar a situação, com a insegurança  alimentar sendo mais severa em áreas empobrecidas e remotas. É necessário adotar estratégias integradas que  abordem a desigualdade econômica e melhorem a eficiência na distribuição de alimentos para enfrentar a insegurança alimentar de maneira mais eficaz.

Authors: Enuwhure Efejero Richard , Mgbemena Chinedum Ogonna , Izelu Christopher Okechukwu
Published: October 2024

This study aims to employ reverse engineering in the development of the Yamaha CY 80 motorcycle clutch hub using end-of-life (EOL) aluminium alloy obtained from automotive vehicle scraps. The remanufactured motorcycle clutch hub underwent characterization and transient thermal analysis by integrating the geometric and structural features of the clutch hub. The EOL aluminium was thoroughly washed with a sodium hydroxide (NaOH) solution, cleaned with running water, and dried under sunlight to remove impurities trapped on the metal surfaces. The EOL aluminium alloy was melted in a gas furnace, and the molten metal was cast into the clutch hub using a permanent mold designed with the geometric features and characteristics of the Yamaha CY 80 motorcycle clutch hub. The EOL aluminium alloy was characterized using Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS). The remanufactured CAD model of the Yamaha CY 80 motorcycle clutch hub was subjected to transient thermal analysis using ANSYS Workbench to predict the thermal behavior of the clutch hub during operation. The FTIR spectra exhibited the following distinctive bands: Al-O stretching modes in octahedral and tetrahedral structures, as well as symmetric bending of Al-O-H, with wavenumbers between 340 and 3131 cm-1 for -OH bonds and between 2109 and 1688 cm-1 for H-O-H bonds. The SEM-EDS micrographs indicated that the two main elements were bromine and silicon. Results from the transient thermal analysis indicated that the minimum and maximum temperatures were 40.109 °C and 250.09 °C within a time frame of 240 seconds. The maximum total heat flux was 30,271,000 W/m2. The compressive yield strength and tensile yield strength obtained in this study were 280 MPa, while the ultimate tensile strength was measured at 310 MPa. The alternating stress levels ranged from 62.05 MPa to 275.8 MPa. This study established that the material is susceptible to fatigue failure, as the alternating stress levels were below the material’s yield strength of 280 MPa.

Melting glaciers, emerging pandemics?
Authors: Chandrakanth Adarshini
Published: October 2024

The world contains over 198,000 to 200,000 glaciers, covering in total over 726,000 square kilometers of Earth’s surface (Davies; “Glacier Quick Facts”). The repetitive cycle of snowfall forming layers and compressing into ice sheets over the course of centuries has allowed the formation of these unique, massive masses of ice. Apart from being huge reservoirs of water, glaciers are also hosts of many interconnected microbiomes, fostering active and dormant bacteria, fungi, viruses and other extremophiles. During the Last Glacial Maximum (LGM), or the peak of the ice age around 23,000-19,000 years ago, the sea surface temperature was at its lowest accompanied by low atmospheric Carbon Dioxide (CO2) concentration (“How Does Present Glacier Extent”; Quamar et al.). This was when glaciers covered over 32% of Earth’s total surface.

However, today, glaciers account for just around 10% of land (“Glacier Quick Facts”). The rise of human choices, especially our indulgence in activities like industrialisation, consumerism and wastage have contributed to the emission of greenhouse gasses, which has in turn led to global warming. A consequence of this phenomenon is the melting of glaciers. Melting glaciers not only results in the release of water and rising sea levels, but also the unveiling of previously trapped microbiomes. This raised the hypothesis that melting glaciers, and other sections of the cryosphere can expose previously frozen, potentially pandemic-causing pathogens to the world. This descriptive research paper will serve the purpose of encapsulating existing research regarding whether the disintegration of the cryosphere can cause pandemics.

Authors:   University of Lucknow, Imurana Halidu , Bhartiya Dr.Anoop Kumar ,   University of Lucknow
Published: October 2024

The new Sustainable Development Goals (SDG3) for 2030 aim to promote excellent health and well-being, as well as reduce mother and infant mortality, by ensuring equal access to reproductive and child healthcare services. Compromises in access to reproductive and child healthcare services in SubSaharan Africa contribute to a rise in maternal and newborn mortality. A desk study was conducted to look into barriers to access and utilization of reproductive and child healthcare services in Sub-Saharan Africa, from the perspectives of both community people and health workers. According to the findings, the most significant hurdles to access and usage of reproductive and child healthcare services are transportation barriers to health facilities, economic considerations, and cultural views, as well as a lack of family support and poor care quality. More study is needed to aid policymakers in taking multi-sectoral action to provide equitable access to reproductive and child healthcare services in line with SDG3 by 2030.

Objective: The objective of the study was to assess the feasibility and clinical effectiveness of pre-emptively fabricated root analogue zirconia implants (RAZI) based on 3-dimensional root surface models obtained from cone beam computed tomography scan (CBCT). Materials and methods: A prospective pilot study was designed on subjects requiring extraction & immediate rehabilitation of tooth. Virtual tooth preparation and extraction was done on the data obtained from CBCT. RAZIs made of high-strength yttrium stabilised zirconia were made with computer aided designing and computer-aided milling (CAD-CAM). The tooth was atraumatically extracted, and immediate implant placement was done. Clinical parameters including gingival index, plaque index, bone loss, pocket depth, and implant stability were assessed. Surface area and volume analysis were performed comparing extracted tooth and implant. Paired t-test and bivariate Pearson correlation coefficient was applied. Results: 2 out of 9 implants survived at 1-year follow-up accounting for a low success rate of 22.2%. Surface area and volume of the RAZI were 9.6% and 10.40% higher than the extracted tooth respectively. Conclusion: The lower success rate of RAZI is attributed to difference in surface area and volume from extracted teeth. Though this technique validates pre-emptive fabrication of RAZIs even before tooth extraction, dimensional error should be minimized to achieve better clinical results.

In this work we have conducted systematic review following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and explore how recent changes in using renewable energy have affected the economy. We have examined 50 articles that were published in peer-reviewed journals between 2010 and 2024. These articles were chosen after a careful screening based on relevance and methodological quality. The main drivers find were technological advancement in solar and wind energy along with policy interventions such as subsidies and carbon pricing. Our main results assert the significant growth in renewable energy capacity with solar energy expanding at rate of 15 percent and wind energy at 10 percent. This growth has been accompanied by a 120 percent increase in investment in solar energy and creation of millions of jobs globally. However, transition also presents challenges particularly, regarding economic impact on traditional fossil fuel industries and the need for equitable acess to renewable resources. While renewable energy adoption offers substantial economic benefits, achieving just transition will require targeted policy interventions and infrastructure investment.

Citizen science has recently emerged as a powerful tool for wildlife monitoring and conservation efforts, offering cost-effective, large-scale data collection that supports traditional scientific research methods. This study explores the integration of citizen science in wildlife monitoring, citizen science data applications and challenges that could be faced, while giving insights on future directions. Citizen- generated data – including observational, environmental, geospatial, acoustic, photographic and genetic information – contribute to population estimations, health and biodiversity assessments, and threat detection. Moreover, the fusion of advanced technologies including mobile applications, web platforms, remote sensing and artificial intelligence has significantly improved data quality, citizen engagement and geographical coverage. However, challenges persist, including concerns about data accuracy, long-term participant engagement and technical knowledge gaps. Addressing these issues through user-friendly technologies and robust training programs is crucial for maximizing the potential of citizen science in wildlife conservation. As global biodiversity faces increasing threats from climate change and deforestation, citizen science offers a vital solution for wildlife monitoring and protection, fostering stronger connections between humans and nature while supporting evidence-based conservation efforts.

Background. Everyone should place a high premium on physical fitness because a fit body allows one to perform everyday chores and responsibilities at their best. Body mass index, which measures dietary status, is one element that affects physical fitness. (BMI). This study intends to assess the physical health and BMI of students at the Adventist University of Indonesia's Faculty of Nursing. With Spearman's rho test, this study technique is quantitative. There were 70 participants who voluntarily and consciously gave their consent. The Zuchora Physical Fitness Test, height measuring equipment, and weight scales were the research tools employed. Results: A significant negative connection between BMI and physical fitness, speed, and arm strength was found using the Spearman Rho test (p.05). Jumping ability, flexibility, endurance, and muscle strength did not have a significant association with BMI (p > 0.05), however. The findings of this study suggest that BMI has an impact on physical fitness in terms of arm speed and strength. The speed and arm strength decrease as BMI increases.

Sleep is a top priority for babies, so that the body can produce growth hormone and also the brain will grow 3 times from birth. In addition, sleep also provides benefits for the mental, emotional, physical health and immune system of the baby. The journal Pediatrics noted that about 33% of babies experience sleep problems, but they are not detected and not handled properly. Almost 72% of parents do not consider sleep disorders in infants as a problem, even though they can interfere with infant growth, cause impaired immune function, and endocrine system regulation (Sekartini &; Adi, 2016). The purpose of the study was to determine the effect of baby massage on the sleep quality of infants aged 0-6 months at TPMB Rosliana – South Tambun in 2022.
