Published: February 2024

Selected physical properties of dehusked coconut as length, width, thickness, geometric mean diameter, sphericity, surface area, bulk density and true density were investigated. Compositional changes in coconut fruits, including volume and weight, shell weight, weight of mature coconut water, wet and dry flesh weight, thickness of the flesh and shell were also evaluated. The average fruit length, major diameter and minor diameter were 99.2±13.3 mm, 91.5±8.9 mm, and 89.5±8.7 mm, respectively; while the sphericity, true density, bulk density and surface area were 0.90±0.05, 998±68.8 kg.m-3, 483±37.3 kg.m-3 and 274.2±50.4 cm2 , respectively. The frequency distribution of the major diameter and the fruit mass followed the Gaussian model. Correlations between fruit characteristics were also determined. Results indicated that fruit weight and total wet flesh weight were closely correlated, and both of these characteristics can be used as an indicator of fruit size.

Inteligencia artificial Vs creatividad musical, ¿sustituto o complemento?
Authors: Bravo Fuentes Paloma
Published: February 2024

La integración de la Inteligencia Artificial en el ámbito artístico despierta interrogantes sobre su capacidad creativa, su influencia en la esencia y apreciación del arte, así como el rol del artista. Esta investigación realiza una revisión sistemática de la literatura para abordar estas cuestiones centrando el foco en la música y conocer la situación del estado del arte. En la actualidad, hay IAs que tienen la capacidad de generar composiciones de manera autónoma, planteando si la percepción de originalidad y belleza cambia cuando es una máquina la que crea. Al simular procesos cognitivos, la IA brinda perspectivas sobre la manifestación de la creatividad humana. Sin embargo, la creatividad de las personas es única, influida por emociones y vivencias. En contraposición, las máquinas se basan en replicar patrones preexistentes, pero con la dirección adecuada, pueden potenciar la creatividad humana. Aun así, requieren calibración constante, confiando en criterios humanos para juzgar su producción. La convergencia de tecnología y creatividad ha llevado a debates éticos y de derechos de autor de las obras. Es crucial que la tecnología esté al servicio del ser humano, subrayando la urgencia de establecer un marco ético firme en nuestra era digital.
COMPARATIVE STUDY FOR RESPONSE TO Cycas circinalis-INDUCED TOXICITY IN LIVER, KIDNEY AND COLON OF RATS AND GUINEA PIGS
Authors: OLUDE O. M. , OMOREGIE F.O.
Published: February 2024

This study evaluated the toxicological response of rats and guinea pigs to Cycas in feed. Ten rats and guinea pigs were randomly designated into two groups for each animal. The control groups were fed with a normal diet while the experimental groups were fed with the Cycas-containing feed for 6 weeks. The effect of the Cycas feed on the animals’ liver, kidney, and colon were evaluated using biochemical and histological assays. The result of the experiment showed changes in body weight and tissue (liver, kidney, and colon) antioxidant levels. Additionally, the animals on the Cycas diet observed an increase in oxidative stress and lipid peroxidation. The histology result for both the rats and guinea pigs revealed that cycasin present in the plant is a potent colon carcinogen, it induced hyperplasia in the colon cells which is a great pointer towards abnormal cell division and hence cancer. We predicted that the plant via its induction of oxidative damage and depletion of tissue antioxidants could drive tissue toward tumorigenesis in both animals. There were significant changes between the (p<0.05) values derived from the different animals. Guinea pigs were more susceptible to the negative effects of the cycasin.

In a nation characterized by diverse economic sectors and challenges such as tax evasion and a significant informal economy, the need for strategic fiscal policies is paramount. This paper explores the multifaceted approach to effective taxation, including broadening the tax base, simplifying the tax system, and utilizing technology for efficient tax collection. Drawing on progressive taxation, incentives for strategic sectors and ensuring transparency, the paper advocates for policies that not only increase revenue but also promote economic stability and social equity. The importance of reducing dependence on oil revenue, enhancing compliance, and encouraging investments is highlighted. In conclusion, it stresses that effective tax policies are integral to Nigeria's economic stability, providing funding for critical sectors such as education and healthcare. The paper emphasizes the significance of these policies in reducing income inequality, fostering entrepreneurship, and creating a conducive environment for business growth. As a recommendation, the paper suggests that policymakers prioritize the implementation of these strategies, invest in modern tax administration technologies, and foster collaboration between government agencies and the private sector. These measures can pave the way for a financially robust Nigeria, ensuring sustainable development and an improved quality of life for its citizens.
Investigating the Healthcare-seeking Behavior among Residents of Otuoke Community in Ogbia Local Government Area, Bayelsa State, Nigeria
Authors: C. O. Ezenwaka , E. V. Uruejoma
Published: February 2024

Health is vital to human living. Poor health in rural areas is prevalent due to various issues impacting health status and service efficacy, with health service functionality measured by affordability and accessibility. Structured questionnaires and oral interviews were employed to investigate the healthcare-seeking behavior of residents of Otuoke community in Ogbia Local Government Area, Bayelsa State. The study established a low response of residents of Otuoke community to biomedical health care (12.8%). Cost (31.4%) was the main limiting factor to seeking health care by the residents. Other factors implicated in influencing healthcare-seeking behaviour include proximity, poor attitude of health care workers, poor medical services and long waiting time in assessing biomedical health care. Most of the respondents resorted to self-examination and self-medication to save cost and time, thereby utilizing the services of local chemists. Traditional healthcare practices still hold sway and gain more relevance based on the fact that it is easily accessible, acceptable and affordable to meet the rural dwellers' expectations compared to biomedical medicine. The study also identified perceived barriers to patronage of the Federal University Otuoke health facility by the students as mainly due to the unavailability of drugs and long waiting time to access medical care. Health education should be deployed to enlighten the residents on rational use of medications and access to treatment at healthcare facilities rather than self-examination and self-medication. University administration should develop strategies to enhance students’ accessibility to the university’s health care services and address the existing barriers.
Algorithms of Encryption Using Graph Theory
Authors: Huda Anwar  , Zill e Shams
Published: February 2024

Encryption plays a vital role in securing sensitive information in various domains from communication networks to financial transactions. Graph theory, with its vast mathematical framework and powerful algorithms, presents a potential method for creating encryption methods. This abstract introduces an algorithm that leveragesgraph theory concepts to provide a symmetric encryption method. Encryption is the process of hiding the original plain-text message by producing a cipher text; decryption is the process of resolving the cipher text to reveal the original plain-text message. In this research, an encryption method based on an idea from graph theory is suggested for encrypting the message. This method stores the original data (plain text) as a complete graph. An encryption table is used for labeling. Some matrix has been modified by using an alphabet encoding table. Ashared key, K, is used which increases the complexity of the cipher text and we provide the decryption process.

Diabetic Nephropathy: Pathogenesis and Drug Delivery System
Authors: Jummah Nurul , Satrialdi Satrialdi , Anita Artarini Aluicia , Anindyajati Anindyajati , Mudhakir Diky
Published: February 2024

Diabetic nephropathy is the leading cause of chronic kidney disease. The pathogenesis of diabetic nephropathy consists of four main pathways that indicate intracellular metabolic abnormalities identified in diabetic nephropathy, namely the activation of polyol and protein kinase C pathways, formation of advanced glycation end products, increased oxidative stress, and intraglomerular hypertension. Conventional treatment approaches for diabetic nephropathy that have been through clinical trials are, among others, the use of glucose-lowering agents, reduction of blood pressure, reduction of capillary permeability, and antioxidants. Although such treatments have been proven to slow the severity of diabetic nephropathy which leads to chronic kidney failure, their effectiveness does not cure diabetic nephropathy in patients. Thus, the modification of drug delivery systems and the widely-performed gene therapy need to be reviewed for their effectiveness with the previous treatments of diabetic nephropathy. This review article discusses the perspective of implementing the most effective diabetic nephropathy treatment system in order to achieve the therapeutic goals of diabetic nephropathy. The modification of drug delivery system and the gene therapies are expected to be able to increase the effectiveness of the drugs and guarantee their safety. The characteristics of the therapeutic targets in each kidney cell need to be understood more deeply so that the therapeutic goals can be achieved. It is hoped that the testing in the clinical phase of diabetic nephropathy by modifications of the drug delivery system and gene-based therapies will be widely carried out in the future.
Chitosan- A Promising agent for site specific drug delivery in periodontics
Authors: D. Shetty Nishmitha , G. Kamath Deepa , J. Shetty Neetha
Published: February 2024

Periodontal diseases are chronic infectious illnesses that have become a significant burden on oral health. Several new treatment targets have been found because of advances in the study of the epidemiology, aetiology, and pathophysiology of periodontitis, as well as the analysis of the polymicrobial interaction in the oral bacterial communities. Efforts to limit growth of bacteria and the formation of substances that eventually damage the tissues supporting the teeth have been the foundation of periodontal therapy. Systemic antibiotic administration for periodontitis has significant shortcomings, attracting attentiontowards the advancement of localized drug delivery systems capable ofmaintaining effective antibiotic concentrations at the intended site throughout the course of treatment with minimum side effects. A controlled release system that can be placed within the periodontal pocket so as to extend therapeutic concentrations at the desired site at a considerably lesser dosage is a pressing priority. Chitosan, a potential carbohydrate biopolymer, is receiving scientific interest in a diverse range of biomedical fields due to its exceptional chemical and pharmacokinetic attributes. Chitosan is a biocompatible and biodegradable naturally occurring polysaccharide with several uses in dentistry owing to its functional versatility and easy accessibility. The applications of chitosan are vast, exciting, and still unexplored. Thisreviewfocusesonthe potential uses of chitosan in periodontology.

The purpose of this exploratory study is to add to the literature on the perceived value of applying IFRS for SMEs standard from the perspective of managers in Jordan’s small and medium-sized enterprises (JSMEs). Based on previous literature and the Value-Based Model Theory, which incorporates the cost-benefit analysis principle, a questionnaire was developed, and 137 valid ones were used to test data regarding the perceived value of appropriateness, possibility, cost, and benefits of implementing IFRS for SMEs standard.The study’s major conclusion found a moderate level of positive consensus about implementation perception; the results also suggested that benefits marginally outweighed implementation costs.The study’s goal is to raise policymakers’ and regulatory experts’ attention to the potential benefits, costs, and obstacles of implementing the standard.this study contributes to international accounting harmonization efforts by demonstrating how Jordanian managers assess the costs, benefits, and opportunities of IFRS for SMEs in JSMEs implementation. This study recommended the following: Expedite the application, conduct thorough IFRS for SMEs awareness and training programs at different levels, and provide financial data for these SMEs in the public interest.Future studies should test new firm variables after the application of this standard and, the reasonable costs and benefits are known.
The Discursive Clash Between the Portraits of Turkey and the Ottoman Empire in Relation to Their Foreign Policy: The ‘Victorious’ Turkey Versus the ‘Defeated’ Ottoman Empire
Authors: Goksel Reyhan Kadriye
Published: February 2024

This article argues that the Turkish press of the early republican years was one of the instruments used by the Turkish political discourse of the early republican years to disseminate and reproduce its values in the public sphere. This article attempts to examine the discursive distinction between Turkey and the Ottoman Empire in terms of their international relations through the Turkish press discourse. To this end, this article focuses on the Turkish newspaper column "Sabah Gazeteleri ne diyorlar?" published in the Turkish newspaper Haber Akşam Postası on June 11, 1938, and conducts an argumentation analysis of the column by applying the Vienna School of Discourse-Historical Approach (Reisigl & Wodak 2001; Wodak 1990, 1994; Wodak & Meyer 2001; Wodak & Chilton 2005; Wodak et al. 2009). This article examines the rhetorical, discursive, and argumentative strategies used by the editorial writer Asım Us to persuade readers. One of the key findings of the article is the following: the negative portrayal of the Ottoman Empire versus the positive portrayal of Turkey. While the Ottoman Empire was described as "defeated" in World War I, Turkey was portrayed as a "victorious" country that was able to sign the Treaty of Lausanne with the Entente powers on an equal footing.

Authors: Machado Marly Stephany Magalhães , Cleophas Maria das Graças
Published: February 2024

Embora exista uma vasta literatura sobre as práticas de feedback e os seus efeitos nos resultados da aprendizagem, são escassas as pesquisas que analisem os efeitos das tecnologias digitais como aporte para fornecer o feedback e promover a regulação metacognitiva dos estudantes. Este estudo teve como objetivos examinar: a) investigar as relações entre o perfil dos professores e a abordagem dessa estratégia no contexto de ensino; e b) identificar as tecnologias digitais utilizadas para o desenvolvimento da regulação metacognitiva em sala de aula. A amostra foi composta por 101 professores de ciências da educação básica pertencentes às cinco regiões que compõem o Brasil. Dito isso, adotou-se uma pesquisa mista, descritiva e exploratória. A coleta de dados se deu a partir de um levantamento survey on-line direcionado aos professores que aderiram à pesquisa. Os resultados constataram diferenças na distribuição das respostas em três aspectos: sexo, região e habilitação em relação aos componentes do feedback, autorregulação e tecnologias, respectivamente. Por fim, espera-se que esta pesquisa possa contribuir para a ampliação do entendimento referente à temática de feedback aliado às tecnologias digitais como estratégia para a regulação metacognitiva.

Published: February 2024

O artigo traz resultados de um estudo que teve como objetivo perceber como ocorre o processo de transição da Educação Infantil para o Ensino Fundamental, na perspectiva das crianças. Trata-se de uma pesquisa de campo realizada em uma escola da rede pública municipal na cidade de Natal/RN, no início do ano letivo. Foram realizadas observações sistemáticas, no período de acolhimento às crianças no 1º ano e duas entrevistas semiestruturadas, individual e coletiva, com 6 (seis) crianças. Autores como Neves (2010),  Faria (2012),  Martinati (2012), Motta (2013), Ribeiro (2014) e Paulino e Queiroz (2018) tratam sobre esse processo de transição e corroboram com a discussão teórica. Com o estudo  percebeu-se os sentimentos de medo e insegurança das crianças, e também de euforia ao ingressar no 1º ano, a ausência que sentem das brincadeiras presentes na educação infantil e o desânimo na realização de atividades repetitivas e sem sentido.
Dispositivos de poder no conviver
Authors: De Morais Michele Luciane Blind , Strieder Roque
Published: February 2024

Diante de pressupostos da modernidade que insistem na preservação da lógica de pensar simplificadora e reducionista, o artigo objetiva aprofundar o debate sobre a avaliação educacional, de modo a elucidar diferentes dispositivos de poder e reflexos na educação brasileira, bem como alternativas possíveis. A perspectiva epistemológica adotada na investigação atende aos preceitos da metodologia histórico-crítica de análise. Consideramos que os pressupostos modernos mascaram a fragmentação de saberes dando ênfase às especialidades e competências. Argumentamos que a avaliação educacional, pós New Public Management, possui dispositivos utilizados para benefícios do capital, recontextualizada de diferentes formas e com interesses prioritariamente mercantilistas, visando vigilância, controle e punição de escolas, diretores, professores e estudantes. Concluímos que a concepção de autopoiese, apostando na autonomia, individualidade e unidade, viabiliza a sustentação de diferentes fazeres docentes.

Published: February 2024

Neste trabalho foram analisadas 7 amostras de pudins, sendo 5 produtos dietéticos e 2 produtos convencionais, de cinco marcas diferentes. Adquiridas em supermercados da Cidade de São Paulo, visando avaliar as informações nutricionais contidas em suas rotulagens. Os pudins foram preparados de acordo com a indicação dos fabricantes e padronizou-se para os dietéticos, o leite desnatado e, para os convencionais, o leite integral. A análise constou da determinação de lipídios, carboidratos, proteínas e do cálculo do valor calórico total. Utilizando-se metodologias descritas nas Normas Analíticas do Instituto Adolfo Lutz. Nos alimentos dietéticos, duas amostras apresentaram valores calóricos bem diferentes dos declarados nos rótulos, onde as calorias se apresentaram, uma subestimada em 63,80% e outra superestimada em 35,93%. Nas demais amostras, inclusive dos produtos convencionais, os valores se encontraram com diferenças menores do que 10,00%. Com relação aos teores de lipídios, somente uma amostra (marca B - convencional) apresentou no rótulo teor concordante com o resultado experimental. Quanto aos teores de glicídios, exceto a amostra (marca B - dietético) que subestimou este valor em 27% no rótulo, todas as outras amostras indicavam nos rótulos, teores deste componente com diferenças abaixo de 10% dos resultados obtidos experimentalmente. Os produtos dietéticos analisados não atenderam aos padrões exigidos pela legislação em vigor. As informações nutricionais apresentadas nos rótulos e embalagens são deficientes e algumas vezes incorretas.

Authors: Luisa Barbosa Maria
Published: February 2024

Os vírus Dengue são arbovírus da família Flaviviridae, com 4 sorotipos antigenicamente distintos. Variações genéticas intraespecíficas entre os mesmos sorotipos, inclusive em uma mesma epidemia, estão bem estabelecidas. O desenvolvimento da técnica de polimerização em cadeia (PC R) é uma alternativa na identificação dos vírus Dengue. Neste estudo construímos dois novos pares de primers para os sorotipos 1 e 2, sem a ajuda de programas de computador. Foram utilizadas como modelo as seqüências genômicas de DEN-1 (Western Pacific), Nauru Island e DEN-2 New Guinea C. Os primers sense 5' ACA AAA AGT GGA GAC CTG GGC TC 3' (D1S) e complementar 5' GTC TAT TCC AAG TCT CTT GGG 3' (DIA) correspondem respectivamente às posições 769 a 791 e 1607 a 1587 do genoma do vírus DEN-l. Estas seqüências reconhecem parte das regiões de membrana (M) e proteína estrutural (E) do genoma do sorotipos 1 e contem 838 pares de bases. A seqüência de primers de DEN-2 foi 5' TGA AGG GGA CGG TTC TCC ATG T 3' (D2S) homólogos aos nucleotídios 1838 a 1859 e 5' GAC TCC CAC CAA TAC TAG TGA CAC 3' (D2A) correspondendo às posições 2312 a 2288. O produto da amplificação foi de 474 pares de bases correspondendo a uma porção do genoma responsável pela síntese da proteína E. A especificidade dos primers foi avaliada por multiplex RT-PCR.
Drosophila melanogaster Meigen: I. Sensibilidade ao Endosulfan e biomonitoramento de seus resíduos em couve-manteiga
Authors: R. de Almeida Garcia , G. R. Reyes Felix
Published: February 2024

A sensibilidade das moscas Drosophila melanogaster ao endosulfan e o seu uso no biomonitoramento dos resíduos do inseticida em couve, foram avaliados. Nas condições do bioensaio, método do filme seco em placa de Petri, o endosulfan se degrada em função da temperatura, sendo mais rápida para o isôrnero alfa do que para o beta. Os bioensaios com D. melanogaster indicaram que a toxicidade do endosulfan aumenta com a temperatura (25 a 35°C) e que as fêmeas são mais sensíveis ao inseticida. Os valores da CL 50, calculados em função da temperatura, variaram entre 4,2 e 11,7 ug/g pc para machos e 2,8 e 8,1 ug/g pc para fêmeas. Os resíduos de endosulfan em couve-manteiga foram determinados pelo método de bioensaio, que apresentou um limite de quantificação da ordem de 0,1 mglkg e reprodutibilidade com coeficiente de variação de 10 %. A validação do bioensaio por cromatografia a gás corrobora a viabilidade do emprego da D. melanogaster no monitoramento de resíduos de endosulfan em couve.

Published: February 2024

As ostras são moluscos bivalves que, com freqüência, são consumidas cruas. Podem ser objeto de processos de depuração (descontaminações físicas e químicas), pois este hábito de consumo está associado a eventos de doenças transmitidas por alimentos em vários países. No presente trabalho, foram realizados testes para verificar a possibilidade de contaminação de ostras em laboratório, com o objetivo de estabelecer modelo para avaliações de processos de depuração. As ostras foram mantidas vivas em água do mar previamente ozonizada. Foi procedida a contaminação da água com Vibrio cholerae EI Tor 01 não toxigênico. Foram realizadas determinações analíticas da água e das ostras imediatamente após e depois de 2, 4, 12, 18 e 24 horas da contaminação. Após 2 horas, as ostras apresentaram positividade para o V. cholerae usado no experimento, em até a diluição 107, igual ao número inicial de células viáveis imediatamente após a contaminação. Os níveis de presença da cepa testada manteve-se elevada, tanto na água como nas ostras, durante todo o período de observação (até a diluição 109 na água e 108 nas ostras). Os resultados obtidos indicam que este método é útil, pois permite a manutenção da viabilidade das ostras. A avaliação da eficácia e eficiência de processos tecnológicos de depuração (descontaminação), como o uso de ozônio e de radiação ionizante, pode ser conduzi da, mantendo os parâmetros reais, inclusive com a presença da microbiota autóctone destes moluscos. A comparação das diluições positivas no decorrer do experimento, demonstram que a cepa adaptou-se às condições do experimento, apresentando inclusive multiplicação. Foram realizados três testes independentes (triplicata), para observar possíveis variações na incorporação da cepa.

Diferentes solventes de extração, assim como técnicas para limpeza de extratos para determinação de rnicotoxinas, tanto clássicas (clarificação, partição) como aquelas envolvendo colunas para extração em fase sólida (sílica, octadecilsilil e imunoafinidade) foram avaliadas para determinação de ocratoxina A em café verde e torrado. Apenas as colunas de imunoafinidade foram capazes de remover os interferentes existentes nos extratos de café permitindo a determinação de ocratoxina A por cromatografia líquida de alta eficiência com detecção por fluorescência em níveis de 0,7 ng/g. Colunas de imunoafinidade de duas marcas diferentes foram testadas com relação à recuperação da toxina e à reutilização em outras análises. Colunas de uma marca apresentaram recuperação média de 97% no primeiro uso e acima de 70% até a quarta utilização. Colunas de uma segunda marca apresentaram recuperação média de 73% no primeiro uso e abaixo de 30% no segundo.

Implications of Artificial Intelligence for Teaching and Learning
Authors: Tang Kuok Ho Daniel
Published: February 2024

Artificial Intelligence (AI) has significantly transformed teaching and learning, facilitating a shift from teacher-centered to student-centered education. This review outlines the broad implications of AI for education and synthesizes both the opportunities and challenges associated with its implementation. Examining over 55 papers related to the impacts of AI on education, the review encompasses various educational contexts, avoiding a singular focus on specific types of education or the teaching of AI alone. According to the review, AI introduces new opportunities for creating intelligent content that enhances learning experiences, fostering interactivity and a student-centered approach. Smart content enables instructors to integrate multimedia, interactive tools, AI-related wearables, and information technologies, diversifying learning modes and engaging students more effectively. The creation of smart content aligns with smart education frameworks to ensure efficient content development. AI also contributes to the development of intelligent tutoring systems, which simulate human tutors to deliver personalized and adaptive educational experiences. These systems can host smart content, enabling independent learning. Additionally, AI improves virtual learning environments by analyzing student data to tailor content and delivery methods based on individual needs. It automates tasks such as grading and feedback, allowing teachers to concentrate on other essential responsibilities. While AI brings significant benefits, it is not without limitations. Challenges include infrastructure requirements, considerations of inclusion and equity, teacher readiness and preparation, data quality and inclusivity, profit orientation, data privacy and ethical concerns, and the potential for unequal access. Addressing these limitations is crucial for maximizing the positive impacts of AI in the realm of education.
Views of school held by children and young people with Down syndrome. How do we ask and what do they report?
Authors: Geiger Sarah
Published: February 2024

Aims

This study investigated the views of children and young people with Down syndrome of their schools, with the aim of increasing the understanding of the features of successful educational placements and the implications for planning, consultation and support.

Methods

The study used a participatory visual interview approach, aiming to reduce language and memory demands and task avoidance due to intimidation.

Findings

The findings indicate that the research techniques used did help the participating young people to highlight experiences and issues that were of importance to them. Their reports about what was good and what was difficult about school are original and enlightening and provide important insights about their experiences and preferences.

Limitations

This was a small, convenience sample and the reporting of interview findings represents the perspective of the participating young people with Down syndrome. Two school tours were limited by restrictions imposed by school staff. School tours and interviews were not repeated. However, the interviews did provide new and unique information about children and young people with Down syndrome’s experiences of school. The study was part of wider research mapping the educational experiences of a large group of children and young people with Down syndrome, identifying predictors, strategies and approaches that contribute to successful placements. Only three young people with Down syndrome were interviewed and this small number affects the generalisability of results.

Conclusions

The study identifies what is valued by the participating young people with Down syndrome, and provides guiding principles and practical implications. It presented an opportunity for children and young people with Down syndrome to communicate their views, and for those views to influence their school experience. Ethical considerations emphasise those relating to the involvement of children and young people with Down syndrome who have additional developmental and communication vulnerabilities. The dissemination supports advocacy at a systemic, school and individual level.
