Published: June 2023

To determine the prevalence and type of anisometropia among school going children and to study association of degree of anisometropia with severity of amblyopia. A hospital based cross-sectional study carried on 500 school going children up to 10th grade (Age group:- 5 years to 16 years) selected by non-probability convenient sampling according to the inclusion and exclusion criteria. The clinical profile of these children was evaluated in department of ophthalmology, P.D.U Govt. medical college, Rajkot and they underwent detail visual assessment and ophthalmic examinations including measurement of uncorrected visual acuity, best corrected visual acuity, auto-refraction, retinoscopy, subjective correction and detailed squint evaluation, if present. During period of November 2019 to February 2021 during school health programme. Total of 500 school going children were enrolled in the study, out of which 221(44.2%) were females and 279 (55.8%) were males. The prevalence of anisometropia in our study was 23.8% (119 childrens out of 500 childrens). Out of total 119 childrens, 47 were males (39.5%) and 72 were females (60.5%). Maximum patients with anisometropia (n=54 out of 119 patients) were having compound hypermetropia. Prevalance of anisometropia increased as the age increased, till age of 14 years, and then again there occurs a declining trend. X2 = 10.139, p value = 0.051 and it was statistically significant. In our study, prevalence of amblyopia was 8.8% (n=44 out of 500 patients) and among amblyopic patients, 59% patients (n=26 out of 44 patients) had amblyopia due to anisometropia. Out of 26 patients with amblyopia due to anisometropia, 73.1% patients (n= 19 out of 26 patients) were anisohypermetropic and 26.9% patients (n= 7 out of 26 patients) were anisomyopic. In our study, depth and prevalence of amblyopia increased as the degree of anisometropia increased and it was found to be statistically significant(p=0.045).Our study concludes that the prevalence of anisometropia was high (59%) among the amblyopic patients with maximum patients having compound hypermetropic anisometropia. Depth and prevalence of amblyopia increased as the degree of anisometropia increased.

: The main objective of the study is to estimate determine the patient demographics, comorbidities, and medications used to treat COVID-19, presenting symptoms and signs, and the outcome of management of COVID-19-associated rhino-orbital-cerebral mucormycosis (ROCM).: A descriptive cross-sectional study was conducted among 50 patients admitted and suspected with Mucormycosis in 3 months duration from May 21 to July 21 Covid pandemic at a tertiary hospital in Villupuram. Written informed consentwas taken from patients or nearest of kin. This study was approved by Institutional Ethical Committee of Villupuram.: 84% patients among suspected mucormycosis were found to be diabetic, with 70% being males and 61.9% had covid history either covid positive or post covid status. About 60% of suspected mucor cases had h/o oxygen treatment and almost 44% had h/o steroid treatment for their covid treatment. Clinically 40% had extraocular muscle involvement in the form of restricted eye movement to total ophthalmoplegia and mortality was ranging from 37.5-57.14%. Those with proper glycemic control and initiation of treatment at appropriate time with endoscopic sinus debridement and antifungal therapy showed better recovery.: The study reveals that COVID-19 associated Mucormycosis has risen dramatically due to interplay of uncontrolled diabetes and in-appropriate corticosteroid use leading to pathogenic invasion and adverse outcomes. The infection has caused high morbidity and mortality among covid positive than post covid patients. It could be minimized by strict diabetic control under appropriate insulin dosage, wise use of steroids/oxygen and timely intervention based on clinical evaluation rather than waiting for investigations could minimize the complications from the infection and shorten the hospital stay.

Authors: Ribeiro Priscilla Ramos Lara , Nunes Piedade João Manuel 
Published: June 2023

O quadro Conhecimento Tecnológico Pedagógico do Conteúdo, do inglês Technological Pedagogical Content Knowledge - TPACK, procura compreender a base de conhecimentos necessária aos professores para que integrem adequadamente as tecnologias em suas práticas. Assim sendo, esta pesquisa investiga as contribuições do TPACK como referencial teórico para programas de formação de professores na área da Educação a Distância (EaD). Verificou-se o impacto de um curso de especialização voltado para a docência em EaD, ofertado por uma instituição pública de ensino superior brasileira (IES), na autoavaliação do conhecimento TPACK dos cursistas, pós-graduandos de uma das universidades públicas conveniadas a esta IES, na integração das Tecnologias de Informação e Comunicação (TIC) em suas práticas docentes. Optou-se por uma abordagem quantitativa, com a aplicação de um questionário com 41 itens, construído e validado exclusivamente para o estudo. Os resultados evidenciam que os participantes (1) consideram a formação obtida como satisfatória; (2) apresentam os maiores níveis de confiança no domínio de conhecimento do conteúdo e suas intersecções; (3) sentem-se mais confortáveis em usar a tecnologia para fazer ciência do que para ensinar e (4) possuem a idade como único dado sociodemográfico que influencia o TPACK. A partir destes resultados, foi possível detectar as demandas formativas dos participantes e vislumbrar futuros redirecionamentos acerca da matriz curricular do curso em análise.

Published: June 2023

Este artigo analisa a plataforma digital de aprendizagem musical Yousician, na perspectiva da teoria dos gêneros textuais, segundo Marcuschi (2002) e dos multiletramentos, à luz de Cope e Kalantzis (2009). A ascensão das plataformas digitais tem contribuído para o surgimento de diversos serviços de aprendizagem musical interativo-digital, fazendo-nos refletir sobre as possibilidades existentes nesses ciberespaços de práticas musicais. A partir de uma pesquisa exploratória, os parâmetros de identificação de gêneros no ambiente virtual de Marcuschi (2002) e as categorias de multimodalidade de Cope e Kalantzis (2009) foram utilizados para situar o Yousician como uma plataforma digital para a construção de significados e práticas. Os resultados alcançados permitiram compreender que as práticas de multiletramentos dos usuários do Yousician transgridem as instruções programadas do sistema e articulam outros cibercontextos, para compensar as limitações educacionais, linguísticas, tecnológicas e temporais da plataforma digital. Os resultados também evidenciaram os diferentes papéis assumidos pelos usuários enquanto aprendizes, mediadores e colaboradores na construção de saberes em rede.

As Limitações da Educação Básica Brasileira Durante a Pandemia da COVID-19
Authors: Ribeiro Victor Barbosa , Silva Andressa Stephanie Fernandes , Santos Nicoli Brandão dos , Teixeira Renata Plaza 
Published: June 2023

Em dezembro de 2019, foi notificado, na China, o primeiro caso do mundo de COVID-19. Já em março de 2020, em função dessa doença, as escolas começaram a ser fechadas no Brasil. Diante desse contexto, o presente estudo teve como objetivo verificar sob a óptica dos professores da Educação Básica brasileira se a educação brasileira estava preparada para toda essa conjuntura promovida pela pandemia da COVID-19. Para tanto, foi aplicado um questionário estruturado em um número máximo possível de professores. A divulgação do estudo perdurou entre os meses de junho e agosto de 2020, via Facebook e Instagram, e teve a intenção de entrevistar uma amostra de conveniência de pelo menos 500 professores. Foi identificado que grande parte deles não estavam preparada para o ensino remoto emergencial (ERE) e que não tinham estrutura de trabalho adequada em suas casas para suas ações. Além disso, relataram que boa parte dos estudantes não participaria ou participaria do ERE e demonstraram receio quanto à possibilidade de aglomerações e contaminação pela COVID-19 em escolas, assim como ansiedade e preocupação quanto ao ERE. Sugere-se que o contexto analisado é suficiente para promover desgastes emocionais e sobrecarga de trabalho. É intuitivo concluir ser necessário que os órgãos governamentais desenvolvam políticas de acompanhamento próximas aos professores, instituindo programas de acompanhamento psicológico, bem como que criem políticas de capacitação em ferramentas tecnológicas de forma contínua e retomem mais políticas de investimentos em educação, melhorando os processos de ensino-aprendizagem e reduzindo riscos de piora das condições de trabalho docente.

La nueva regulación del delito de uso fraudulento de medios de pago distintos del efectivo al albur de la reforma de 22 de diciembre de 2022: Un análisis del art. 249.1 b) y 249.2 b) del CP
Authors: Abadías Selma Alfredo 
Published: June 2023

Indudablemente, nos ha tocado vivir en unos tiempos complejos y cambiantes que afectan a muchas facetas de nuestras vidas, y por supuesto a la realidad delictiva. Desde una contextualización y ejemplificación detallada de los cambios históricos que nos han llevado al momento actual, en el presente artículo pretendemos abordar la reforma del CP de 22 de diciembre de 2022, centrándonos en el art. 249.1 b) y 249.2 b), que penaliza el uso fraudulento de los medios de pago distintos del efectivo metálico, y que toma sustento en la Directiva 2019/713, de 17 de abril, del Parlamento Europeo y del Consejo, sobre la lucha contra el fraude y la falsificación de medios de pago distintos del efectivo, por la que se sustituyó la Decisión Marco 2001/413 JAI, del Consejo. La citada y necesaria reforma del delito de estafa del art. 249 CP, que entendemos que proviene de una obsolescencia causada por los avances tecnológicos raudos e imparables de los últimos tiempos, incorpora una serie de medios de pago indeterminados o abiertos «…cualquier otro instrumento de pago material o inmaterial distinto del efectivo o los datos obrantes en cualquiera de ellos», que aperturan cierta incertidumbre en relación con la seguridad jurídica y su eficacia real en la lucha contra el delito, y por ende para el servicio a la ciudadanía, y sobre todo, para aquellos colectivos más vulnerables. Ello requiere una reflexión que toma como base la jurisprudencia y la doctrina científica más autorizada para realizar una exégesis crítica del tipo y ofrecer propuestas concretas que aquí proponemos.

A vueltas con la universalización del derecho a la educación superior. El caso de la docencia semipresencial en la educación a distancia: Profesores tutores en la UNED
Authors: Alguacil González-Aurioles Jorge 
Published: June 2023

La educación semipresencial, que desde un primer momento oferta la UNED, procura contribuir a hacer efectivo, en toda España, al menos parcialmente, el derecho a la enseñanza superior universitaria; de la mejor o peor regulación de esta forma de transmisión del conocimiento dependerá, en buena lógica, la realización efectiva de tal derecho. Se estudia así la forma de organización de esta Universidad, particularmente la regulación de la figura del Profesor Tutor, docente específico de esta Universidad, clave para asegurar este modelo de enseñanza. Los problemas que derivan históricamente de la regulación de esta figura se acrecientan con motivo de la adhesión de España al Espacio Europeo de Educación Superior, pues este proceso revaloriza aun más la función tutorial. De las posibles soluciones al problema, parciales, y generales, cabe extraer ciertas conclusiones.

THE INFLUENCE OF EXTERNAL FACTORS ON THE ACCURACY AND RELIABILITY OF THE DETERMINATION OF ULTRA-LOW POWER ELECTRIC FIELDS
Authors: Tychkov Dmytro , Voloshko Oksana 
Published: June 2023

The article presents the results of an experimental study of the influence of temperature, relative humidity of the surrounding environment, as well as the coefficient of electromechanical action on the process of determining ultra-low power electric fields. The analysis of the obtained results made it possible to establish the most rational conditions for determining the force (electrical tension) and energy (distribution of surface charge and electric capacity) parameters of such fields with higher accuracy and reliability. The paper proposes an experimental experiment to establish the accuracy and reliability of power and energy parameters for determining electric fields under conditions of changes in climatic factors and the electromechanical coefficient, the implementation of which took place on a measuring stand developed with the participation of the authors. The main element of such a measuring stand is an automatic device for determining, collecting and processing information on the distribution of power and energy parameters of the electric field under the sensitive element of the measuring transducer. The results obtained as a result of the experimental research made it possible to establish that the coefficient of electromechanical influence has a decisive influence on the accuracy of measuring electric fields of ultra-low power. It is shown that an increase in the coefficient of electromechanical influence from 38 pN/V (silicon <111>) to 190 pN/V (PZT-8 piezoelectric ceramics) leads to an increase in the relative error of electric field determination by 4.7%. It was established that reducing the temperature to 20 °C while maintaining the relative humidity from 38 % to 74 % leads to a decrease in the relative error by 1.5-2.2 %. At the same time, a decrease in temperature with a simultaneous decrease in relative humidity leads to an increase in the reliability of the determination of electric fields (so, the probability of error-free measurement of power and energy parameters of electric fields increases by 18 %). A comparison of the results obtained by the proposed method with the results obtained by atomic force microscopy method (in the mode of measuring the leakage currents from the working areas of the investigated surfaces) was carried out, which showed a strong positive correlation between these results, which confirms the objectivity of the proposed method and the adequacy of the obtained results. The conclusions and analyzed data obtained in the article based on the results of experimental studies can be used to create a system of automatic error correction and instability determination of power and energy parameters of ultra-low power electric fields, taking into account limiting external influences.
Modified Nonlinear Hysteresis Approach of a Tactile Sensor
Authors: Hussain Gasak Abdul , Holderbaum William , Theodoridis Theodoros , Wei Guowu 
Published: June 2023

Soft tactile sensors based on piezoresistive materials have various large-area sensing applications. However, their accuracy is often affected by hysteresis, a phenomenon that poses a significant challenge during operation. This paper introduces a novel approach that employs a backpropagation (BP) neural network to address the hysteresis nonlinearity in conductive fibre-based tactile sensors.
To assess the effectiveness of the proposed method, four sensor units with different layer configurations (1, 3, 6, and 12) were designed. These sensor units underwent force sequences to collect corresponding output resistances. A backpropagation network was trained using these force sequences, thereby correcting the resistance values. The training process exhibited excellent convergence, effectively adjusting the network&#039;s parameters to minimize the error between predicted and actual resistance values. As a result, the trained BP network accurately predicted the output resistances.
Several validation experiments were conducted to highlight the primary contribution of this research. The proposed method reduced the maximum hysteresis error from 24.2% of the sensor&#039;s full-scale output to 13.5%. This improvement establishes the approach as a promising solution for enhancing the accuracy of soft tactile sensors based on piezoresistive materials.
By effectively mitigating hysteresis nonlinearity, the capabilities of soft tactile sensors in various applications can be enhanced. These sensors become more reliable and more efficient tools for force measurement and control, particularly in the fields of soft robotics and wearable technology. Consequently, their widespread applications extend to robotics, medical devices, consumer electronics, and gaming.
Notably, the complete elimination of hysteresis in tactile sensors may not be feasible. Nevertheless, the proposed method effectively modifies the hysteresis nonlinearity, leading to improved sensor output accuracy.
