In the current globalization trend, introducing preschool children to English is an important “strategy” to help children form and develop skills in using English as a second language. Rhyming poems with rhyme, rhythm and repetition of words and sentence patterns significantly encourage preschool children to acquire English vocabulary. This effective tool supports language learning through a fun and memorable learning experience. Using document research and analysis, synthesis and comparison, the article points out three measures to use rhyming poems to develop English vocabulary for preschool children aged 5-6, which are: Selecting rhyming poems with vocabulary appropriate to the child's ability; Composing rhyming poems on familiar topics; Creating interactive situations in the process of organizing activities using rhyming poems to develop English vocabulary for children aged 5-6. By enhancing vocabulary development through engaging rhymes, teachers can create a stimulating learning environment that supports children's language acquisition and encourages their love of learning English at later stages.

The study aimed to expand the behavioral analysis of the Theory of Planned Behavior (TPB) to examine COVID-19 vaccine willingness among breast cancer patients. While both the WHO and the U.S. CDC have utilized adapted versions of the Increasing Vaccine Model to study vaccination trends across various populations and industries, limited research has explored vaccine acceptance in specific groups such as breast cancer patients. From May to July 2022, an online cross-sectional study was conducted in Taiwan, coinciding with the initial COVID-19 vaccination rollout. A total of 278 participants were included in the statistical analysis. Structural Equation Modeling (SEM) was employed to assess the conceptual validity of the measurements and test the proposed model. The analysis revealed that the model explained 36.8% of the variance in patients’ willingness to receive the COVID-19 vaccine and 40.3% of the variance in predicting future vaccination behaviors based on regret following vaccination. Fear of COVID-19 was found to indirectly influence vaccination willingness through shared decision-making, highlighting the importance of discussions between patients and their physicians. Patients who had more opportunities to consult with their doctors were more inclined to get vaccinated. Moreover, fear of COVID-19 enhanced the trust breast cancer patients placed in their physicians. However, decision conflicts and shared decision-making impacted vaccine willingness independently and directly, rather than through the mediating effect of trust in physicians. Furthermore, the study confirmed that patients who hesitated to get vaccinated were more likely to experience regret. These findings provide valuable insights into the behavioral aspects of vaccination among cancer patients, offering strategies to mitigate fear and improve preventive health measures.

Obra de teatro clown para el abordaje didáctico de la diversidad de cuerpos en la educación cultural y artística
Authors: Almeida Correa Paula Isabel
Published: January 2025

La siguiente investigación tiene como objetivo crear una propuesta artístico-didáctica acerca de la diversidad de cuerpos, a través del lenguaje clown y el teatro para acompañar los procesos de autopercepción y construcción de imagen corporal de los adolescentes pertenecientes a la Educación General Básica Subnivel Superior. La obra pretende propiciar un espacio de debate para repensar y deconstruir los ideales de belleza hegemónicos y estereotipos que propician una percepción distorsionada de los cuerpos, provocando inconformidad con la propia imagen corporal. Debido a esto se vuelve necesario generar este espacio de convivio teatral, donde se validen las opiniones y pensamientos de los estudiantes para cuestionar el imaginario colectivo sobre el cuerpo y la autopercepción, que se ha instaurado en el último tiempo. La obra de teatro se presenta como una propuesta artístico-didáctica que se sostiene en el Currículo del Ministerio de Educación, y que aporta a las materias de Educación Cultural y Artística y la de Educación Física.

Sexualidade, erotismo e transgressões da professora primária no romance “Menina que vem de Itaiara” (1996), de Lindanor Celina
Authors: NERY Guthemberg Felipe Martins , ALVES Laura Maria Silva Araújo
Published: January 2025

O objetivo deste texto é analisar os comportamentos transgressores praticados por uma professora nas vivências de sua sexualidade e erotismo em sala de aula do magistério primário no início do século XX, utilizando a narrativa da professora adjunta Ivanildes, personagem descrita no romance "Menina que vem de Itaiara" (1996), da escritora paraense Lindanor Celina. O romance é ambientado entre os anos de 1920 e 1930, período em que a figura feminina atuante no magistério é representada sob a imagem da “professora ideal”, uma profissional de corpo assexuado e desprovido de qualquer desejo sexual e erótico. A personagem Ivanildes, mulher dona de si, representa a transgressão contra o modelo de professora vigente, pois em sua atuação em sala de aula buscava formas de sentir e expressar suas paixões, seduções, desejos sexuais e atitudes eróticas no ambiente escolar primário de uma pequena cidade do interior paraense.

Conservação ambiental e o desenvolvimento urbano: uma análise sobre os instrumentos de educação ambiental do Jardim Zoobotânico da Amazônia
Authors: Avelar Marcilene Calandrine de , Pontes Altem Nascimento , De Paula Manoel Tavares
Published: January 2025

O desenvolvimento urbano e a sustentabilidade ambiental são fenômenos que estão intrinsecamente ligados à qualidade socioambiental de uma cidade. A manutenção dessa relação depende, dentre outros, da efetivação de políticas ambientais que visem agregar os aspectos históricos, culturais e ecológicos no processo educativo em ambiente não formal, como em Unidades de conservação urbanas (UCUs). Diante disso, este estudo objetiva investigar as percepções sobre as funções socioambientais, os instrumentos legais e as práticas de educação ambiental no contexto do Bosque Rodrigues Alves-Jardim Zoobotânico da Amazônia (BRAJZBA), relacionando-os com as tendências político-pedagógicas de educação ambiental. A área de estudo está localizada na cidade de Belém, Pará, Brasil. Trata-se de uma pesquisa qualitativa, cujos dados foram coletados por meio da aplicação de um questionário e de análise documental. A Análise de Conteúdo (AC) é a metodologia adotada para investigar os dados obtidos. Os resultados demonstraram que as funções ambientais se sobressaem às funções sociais na percepção dos funcionários. Além disso, as previsões para a educação ambiental contidas nos instrumentos legais que embasam o Regimento Interno do BRAJZBA, em sua maioria, estão alinhadas às tendências político-pedagógicas: conservacionista e pragmática. Já as práticas de educação ambiental revelam a aptidão dessa unidade de conservação como espaço educador e construtor da consciência ambiental. Todavia, essas ações ainda precisam ser fortalecidas para agregar uma vertente formativa menos conservacionista e mais emancipadora e promotora de transformação social.
Current State, Challenges and Opportunities to Improve Faba Bean Cultivation in Morocco: A Review
Authors: Chetto Oumaima , Kouighat Mohamed , Kouighat Mohamed , Nabloussi Abdelghani
Published: January 2025

Faba bean (Vicia faba L.) is a leguminous crop renowned for its millennia-long cultivation driven by its highly nutritious seeds. Rich in minerals, bioactive carbohydrates, fiber and protein with a complete amino acids profile, faba beans serve as vital components in both human and animal diets. In Morocco, faba bean is crucial for food security, sustainability and rural economy. After stable cultivation in the 1960s-70s and subsequent expansion, recent years have seen a decline in cultivated areas due to market volatility, climate challenges, traditional farming methods, pests and limited research. Addressing these multifaceted challenges requires a comprehensive approach. Key strategies include the adoption of alternative agricultural practices such as no-till farming to enhance soil quality and reduce labor costs. Implementing effective weed management strategies and increasing mechanization are crucial for reducing labor requirements and improving overall productivity. Additionally, breeding programs focused on developing drought-tolerant and high-yielding faba bean varieties are essential. Preparing solutions for emerging pests like aphids and pod borers, which thrive in the shifting hotter and drier climate, is critical. Adopting regional/agroecological varieties and developing open-pollinated and synthetic varieties for the national catalog are important considerations. To combat crenate orobanche, extensive screening of accessions and developing herbicide-resistant varieties should be prioritized. The integration of molecular tools, such as marker-assisted selection and genomic prediction, is crucial for accelerating the breeding process and enhancing precision in developing resilient varieties. Finally, emphasizing scientific research to optimize agronomic practices and reinforce crop resilience stands as a critical priority. This review evaluates the current status of the faba bean sector in Morocco, identifying the obstacles faced by farmers amidst economic, environmental and market fluctuations. It proposes essential strategies aimed at advancing faba bean production in Morocco, serving as a fundamental resource and reference for stakeholders including farmers, researchers, seed producers and policymakers.

Online learning is a relatively new thing for some teachers in South Kalimantan. It was the first time for these teachers to do online learning since the government took the policy of learning from home due to the disaster emergencies and environmental change. This study aims (1) to determine the perception of geography teachers in South Kalimantan who have just done online learning for the first time, and (2) to determine the quality of online learning that has been implemented based on the mean index value of each factor. The research was designed with a quantitative approach through an online survey of 26 geography teachers who teach 10th grade at the high school level. The sample was selected by Cluster Random Sampling. The questionnaire instrument used a modified the online learning quality index based on teachers and learners’ perceptions (OLQ-TLP). The research time was from December 2020 to February 2021. The results showed that teachers' perceptions of online learning were in a good category. Based on the index value, factors that have good quality are Learner content, Learner interaction, Instruction interaction, Social Presence, and Course design. Other factors still need to be improved, namely the factors of Learner satisfaction, Knowledge acquisition, Learning platform, Instruction, Learning support, and Ability of transfer. Therefore, to improve teachers' expertise in online geography learning on lithosphere material, training with an innovative Digital Education Shifting (DES) approach is needed.

Published: January 2025

A estimativa da evaporação em reservatórios artificiais, especialmente em regiões semiáridas, é relevante para o planejamento de políticas de gestão e gerenciamento dos recursos hídricos. Com isso, objetivou-se avaliar a estimativa da evaporação de água em um reservatório no estado do Ceará, utilizando diferentes métodos, e compará-los entre si, para a obtenção de coeficientes de correção da evaporação do tanque Classe A. A área selecionada para estudo foi o reservatório Santo Anastácio, localizado na cidade de Fortaleza (CE). Dados de precipitação, temperatura do ar, velocidade do vento, umidade, insolação total e evaporação do tanque Classe A foram medidos diariamente e avaliados, no período de 2007 a 2019. Posteriormente, estimou-se a evaporação através dos métodos de Penman (1948), Linacre (1977), Linacre (1993), Kohler et al. (1955) e Thornthwaite (1948). Estes foram comparados com os dados medidos de evaporação obtidos do tanque Classe A (ECA). Os resultados mostraram valores anuais de evaporação acumulados – variando entre 1602,52 mm e 3657,95 mm. Foram encontrados coeficientes de correção do tanque Classe A mensais genéricos entre 0,61 e 1,59; sazonais “chuvoso” de 0,79 e 1,45 e “seco” de 0,61 e 1,11; e anuais oscilando entre 0,74 a 1,29. Os coeficientes dos métodos de Linacre (1977), Kohler (1955) e Thornthwaite (1948) tiveram valores equivalentes. O modelo de Penman (1948) apresentou os maiores valores. De um modo geral, os coeficientes de correção do tanque Classe A obtidos por todos os métodos tendem a superestimar a evaporação no Açude Santo Anastácio (ASA). Porém, este trabalho sugere que o modelo de Linacre (1977) é o mais realista, seguido por Thornthwaite (1948) e, por último, Kohler et al. (1955). Esta pesquisa almeja contribuir para a gestão operacional dos reservatórios em regiões semiáridas, através da aplicação de ferramentas matemáticas e métodos de medição acessíveis.

In the pursuit of sustainable and clean energy sources, the development of efficient electrocatalysts for hydrogen evolution reaction has gained significant attention. In this work, we synthesized single-atom Fe-doped 1T MoS2 (sFe-1T/MoS2) nanosheets using a one-step hydrothermal method, harnessing the synergistic effects of iron-intercalation to enhance hydrogen production through an abundance of active sites. Notably, 10 at. % sFe-1T/MoS2 exhibited excellent hydrogen evolution reaction performance with a low onset potential of 190 mV and a Tafel slope of 55 mV/dec in acidic solution. High performance was also achieved in alkaline solutions. Additionally, these catalysts demonstrated excellent efficiency in seawater splitting. This work not only offers a cost-effective and scalable method for producing high-quality electrocatalysts but also sets a precedent for the application of this technology across various catalytic systems, marking a significant advancement in clean energy research.
The epidemiology of invasive Haemophilus influenzae in Northwestern Ontario from 2021 to 2022
Authors: Shortreed Hannah , Ulanova Marina
Published: January 2025

Invasive Haemophilus influenzae disease, particularly caused by serotype a (Hia) and non-typable (NTHi) strains, is prevalent in northwestern Ontario, Canada and can cause serious illness. This study reviewed epidemiological data for seven cases of invasive H. influenzae disease that presented over a 20-month period at the regional hospital serving northwestern Ontario. One pediatric and six adult cases with the following blood isolates were reported: 2 Hia, 2 NTHi, 2 serotypes f (Hif) and 1 serotype e (Hie). These findings demonstrate the consistent presence of Hia and NTHi as causes of serious disease in the region, preferentially affecting adults. Most patients in this cohort presented with pneumonia (71.4%) or bacteremia (57.1%). Two unique adult cases, bacteremia caused by Hie and epiglottitis secondary to Hif, were reported. This study highlights the need for ongoing surveillance of invasive H. influenzae disease in the region. The continuing presence of Hia supports introducing a new Hia vaccine, which is undergoing clinical trials in Canada, for immunization of groups at risk of invasive Hia disease.

Electrochemical DABCOylation enables challenging aromatic C–H amination
Authors: Malapit Christian , Stewart Griffin , Alvarez Eva Maria , Rapala Chris , Sklar Jonathan , Kalow Julia
Published: January 2025

The selective amination of aromatic C–H bonds is a powerful strategy to access aryl amines, functionalities found in many pharmaceuticals and agrochemicals. Despite advances in the field, a platform for the direct, selective C–H amination of electronically diverse (hetero)arenes, particularly electron-deficient (hetero)arenes, remains an unaddressed fundamental challenge.1-10 In addition, many (hetero)arenes present difficulty in common selective pre-functionalization reactions, such as halogenation11, or metal-catalyzed borylation12 and silylation13. Here, we report a general solution to these limitations that enables selective C–H amination across a comprehensive scope of (hetero)arenes. Key to this strategy’s success is the oxidative generation of highly electrophilic N-radical dications from bicyclic tertiary amines (DABCO) that reacts across a wide range of arenes with high selectivity. Notably, this platform constitutes the first anodically generated N-radical cations that engage in aromatic C–H amination over well-reported hydrogen atom transfer (HAT) with weak C­–H bonds.14-16 This C–­H amination reaction that allows selective functionalization of both electron-rich and deficient arenes, as well as pyridines, is a rarity in the general area of non-directed aromatic C–H functionalization.1-4 This sustainable electrochemical DABCOylation reaction provides access to many complex drug-like aryl- and pyridinylpiperazines with high functionality tolerance, chemoselectivity, and site-selectivity.17
Unravelling the mystery: The key role of tides in strengthening AMOC during the Bølling-Allerød epoch
Authors: Chen Yugeng , Song Pengyang , Sun Yuchen , Chen Xianyao , Lohmann Gerrit
Published: January 2025

The Bølling-Allerød (BA) period, characterized by rapid climate warming, provides a unique opportunity to study the dynamics of the Atlantic Meridional Overturning Circulation (AMOC). Despite expectations that the AMOC would weaken due to substantial meltwater input from Northern Hemisphere ice sheets, proxy data evidence suggests it unexpectedly strengthened during this transition. In this study, we examine the previously unconsidered role of tides during the BA period through a series of ocean circulation model simulations. Our findings indicate that enhanced tidal mixing during the BA significantly contributed to the rapid amplification of the AMOC, also increasing its resilience to freshwater inputs from deglaciation.

The final decision of the 2023 United Nations Conference of the Parties (COP28) called for transitioning away from fossil fuels, sparking a growing interest in the full phase-out of fossil fuels1. Integrated assessment and energy system models have outlined energy system transformation pathways to limit global warming to 1.5°C2,3. However, pathways towards a full phase-out of fossil fuels, which may require additional efforts beyond those for the 1.5°C goal, remain unclear4. Here, we employ two global energy system models to explore energy system transformations, and the challenges and opportunities related to attaining zero-fossil (ZF) energy systems. Our results showed that reaching a ZF goal by 2050 would accelerate direct and indirect electrification, involving 1.6–1.8-fold increases in total power generation compared to the cost-optimal 1.5°C pathways. This transformation would inevitably increase cumulative energy supply investments within this century by up to 30% and require the rapid scaling of technologies such as solar and wind power, as well as electrolysers in the near term. Despite opportunities including reduced climate impacts and lower reliance on carbon dioxide removal from the energy and land use sectors, these challenges imply that international society must approach the transition towards ZF energy systems with strong determination.

The evolution and functional genomics of the biosynthesis of secondary metabolites, including production of hydrogen cyanide (HCN), is a major goal in Lima bean research. This work describes our latest findings in short time evolution, genomics and expression, applied to Lima bean. This includes a chromosome-level assembly for the Andean gene pool and long-read sequencing of wild relatives. Large indels explained by transposable elements affect promoter regions of several genes related to domestication traits. The two major gene pools of P. lunatus diverged within the last million years, but recent insertions of LTRs produced important variations in genome size and composition. A core metabolic network for Phaseolus revealed patterns of variability in RNA expression for genes related to different primary and secondary metabolic processes. The Phaseolus genomes have important differences in the number, location, and expression of genes, which can explain the unique ability of Lima bean across domesticated Phaseolus species for production of HCN.

Disease attacks on crops like maize pose a significant threat to the global food supply chain in Africa, particularly in West Africa. Maize is a staple food source and the economic backbone of the population and farmers in West Africa. In recent years, maize yields have declined due to diseases. Systematic solutions, such as visual inspection through laboratory experiments for disease diagnosis, have not led to a significant improvement in production or ensured sustainable food security in Africa. In response to this challenge, we introduce a lightweight deep-learning ensemble model for early disease detection in maize plants. The study focuses on developing and validating a model specifically designed to identify and classify diseases in maize plants. We use computer vision technology to capture intricate patterns in maize leaf images. The model is trained to recognise six classes, with five representing different diseases and one representing a healthy state. In this paper, we explore the amalgamation of Residual Network (ResNet9) and Efficient-Net-b4 (ENetb4) as a pre-training model built on convolutional neural networks (CNN) to improve accuracy and robustness in maize disease detection and prediction. The results of the study indicate significant opportunities for improvement in agricultural technology in West Africa. For instance, the ResNet9 model accurately identified diseased images of maize crops with a performance accuracy of 98.2%, while the (ENetb4) model achieved a performance accuracy of 94.3% in the same task.
Abdominal cerebriform intradermal nevus in a 22 years old female in the Eastern Region of Democratic Republic of Congo, A psychodermatological case report
Authors: Gaylord INENA WA INENA
Published: January 2025

Cerebriform intradermal nevi (CIN) are a rare subtype of intradermal melanocytic nevi, distinguished by their characteristic surface morphology that resembles the gyri and sulci of the human brain. Typically presenting as benign skin lesions, these nevi occur predominantly as congenital formations, often evident at birth or during early childhood.Females are more affected. CINs generally manifest in areas such as the scalp and face and can be mistaken for malignant conditions due to their distinctive appearance and potential for growth, which may be influenced by hormonal changes, particularly during puberty and pregnancy.
An early diagnosis is crucial due to the associated risk of malignant melanoma, with lifetime incidence rates of melanoma in CINs ranging from 6.3% to 12%. Diagnosis is primarily clinical, supported by dermoscopy and, in uncertain cases, histopathological examination. Treatment options depend on factors such as cosmetic concerns and suspicion of malignancy, with complete excision being the most common intervention.
This case report details a 21-year-old female patient with a cerebriform lesion on her flank, exacerbated by postpartum hormonal changes. The report highlights the psychological impact of such skin conditions, as the patient experienced anxiety and depression related to her lesion. Following a successful excisional biopsy and psycho-educational support, her mental health improved significantly. This case emphasizes the importance of recognizing the psychological implications of CINs and adopting a biopsychosocial approach to patient management to ensure optimal outcomes and patient satisfaction.

Penile carcinoma (PeCa) predominantly affects less developed regions of the world. Its risk factors include poor genital hygiene, phimosis, and HPV (Human Papillomavirus) infection. Angiogenic activation is essential for the survival of neoplastic cells; however, there is limited data on this process in PeCa. The present study aims to review and correlate HPV infection with the angiogenic process in PeCa. A total of 66 articles were analyzed, all with a diagnosis of squamous cell carcinoma of the penis, diagnosed between 1994 and 2017, and associated with HPV infection. The review included the markers CD34, CD31, and CD105, as well as pro-angiogenic factors (VEGF, VEGFR1, and VEGFR2). Only neoangiogenesis, marked by CD105, was more pronounced in cases associated with high-risk HPV. This suggests an adjunct mechanism of neoangiogenesis promoted or facilitated by this virus. Additionally, other markers such as VEGF, VEGFR1, and VEGFR2 showed no significance in the analyzed articles, and there was no consensus regarding the use of p16INK4a as an HPV marker.
Korisna besmrtnost duše
Authors: Finci Predrag
Published: January 2025

Immanuel Kant diskutira problem duše u svim trima svojim Kritikama na različit način. U Kritici čistog uma Kant ukazuje na ograničenja duše u spoznavanju subjekta. U Kritici praktičnog uma ideja duše od pomoći je u reguliranju moralnih pitanja, dok u Kritici moći suđenja Kant shvaća dušu kao stvaralačku sposobnost i moć subjekta, koja je dobra ako je korištena s mjerom. Težište je ovog rada na Kantovu razumijevanju »besmrtnosti duše« u njegovoj drugoj Kritici kao nužne pripomoći u štovanju moralnog zakona.
Koliko učitelji likovne kulture u Sloveniji prate likovnu umjetnost? Analiza prema dobi i radnom stažu

Published: January 2025

Kvalitetan likovno-pedagoški rad od učitelja zahtijeva stalno stručno usavršavanje te praćenje likovne prakse i likovnih izložbi. Kako se umjetnost mijenja, mijenja se i društvo, a tako i škola. Ako učitelj želi osvježiti sadržaj i približiti ga učenicima, on onda mora pratiti promjene. U ovom članku predstavljamo dio šireg istraživanja u kojemu nas je zanimao osobni interes učitelja za praćenje likovne prakse. Istraživanje je provedeno na uzorku od 84 učitelja likovne kulture u višim razredima osnovne škole iz cijele Slovenije (N = 84). Interes učitelja analizirali smo s obzirom na dob i radni staž. Zanimalo nas je jesu li dob i radni staž čimbenici koji utječu na osobni interes učitelja likovne kulture i nastavak njihova profesionalnog usavršavanja. Rezultati pokazuju da učitelji, bez obzira na dob i radni staž, pokazuju sličan interes za umjetničke prakse.
Academic dishonesty in written assignments
Authors: Šimon Jana , Pavlin-Bernardić Nina
Published: January 2025

This study focused on the role of contextual factors and self-efficacy for self-regulated learning, as well as achievement goals as motivational determinants of academic dishonesty in written assignments among higher education students. We aimed to explore the potential mediating role of self-efficacy for self-regulated learning and achievement goals in the relationship between contextual factors and academic dishonesty in written assignments. 414 students from three social and humanities faculties of the University of Zagreb participated in the study. Students filled out the questionnaire which included measures of contextual factors of academic dishonesty, self-efficacy for self-regulated learning, achievement goal orientation, and rate of engagement in academic dishonesty in written assignments during their studies. Contextual factors predicted academic dishonesty in written assignments both directly and via self-efficacy for self-regulated learning and work-avoidance goal. The findings indicate the importance of both context of learning and motivational beliefs in understanding academic dishonesty in higher education.
