Purpose. Analysis of refractive errors’ frequency in children with retinoblastoma.

Patients and Methods. A retrospective study included 57 children with retinoblastoma (31 male and 26 female) who received treatment in 2013–2017. The criteria for patient selection was the presence of mono- or bilateral retinoblastoma, as well as autorefractometry of both eyes before treatment. In all cases, the study was performed with cycloplegia. The parameters studied included gender, age at the time of the initial examination, visual acuity, spherical and cylindrical component of refraction, the axis of the cylinder.

Results. Bilateral retinoblastoma was determined in 34 children (59.6 %), the average age of the patients was 18.0 ± 2.6 months. Monolateral retinoblastoma was detected in 23 patients (40.4 %), the average age at the time of check-up was 26.2 ± 3.1 months. In total, anisometropia of more than 2.0 diopters was detected in 14 patients (24.6 %), of which with monolateral RB in 6 patients (26.1 %) and in bilateral patients in 8 (23.5 %). In 26 cases (45.6 %) anisometropia was determined from 1.0 to 2.0 diopters, of which 41.1 % (n = 14) with bilateral lesion and 52.1 % (n = 12) with monolateral. The frequency of hyperopia over 3.0 diopters in the total cohort was 25.2 %, myopia 3.3 %. Significant differences (p = 0.025) were obtained by comparing the frequency of astigmatism determination of more than 1.0 D (39.6 % in the total cohort versus 13.0 % for healthy eyes). When analyzing the frequency of ametropia depending on age, a trend was observed (0.05 < p < 0.1) to reduce the frequency of hypermetropia and increase the frequency of astigmatism. Additionally, an analysis of the astigmatism’s frequency depending on the tumor localization was made. Patients with central or paracentral localization of the tumor lesion amounted to 69.4 % (n = 25), and from the peripheral — 30.6 % (n = 11) (p = 0.002).

Conclusions. In this paper, we analyzed the frequency and nature of refractive errors in children with monolateral and bilateral retinoblastoma. The identified risk factors may affect the development of refractive amblyopia in children with retinoblastoma in more adulthood, which requires the development of an individual approach to the correction of refractive disorders taking into account the localization of tumor foci, the nature of the lesion and the individual characteristics of patients.

Published: April 2020

Introduction: Noise is one of the most important pollutants in worksites. Hospitals are imposed to noise pollution.  Considering lack of research in Sari educational hospitals and applicability of noise control by engineering controls and education, we proposed this research to evaluate the sound pressure level (SPL) in three educational hospitals of Sari, Iran.
Methods: In a descriptive-analytical study, the SPL of three hospitals was evaluated using sound level meter (model; CACELLA CELL-490, made in England). The evaluation was performed in 1.5 meter height, in three shifts, and in three days of the week. Data were analyzed using descriptive statistic methods and SPSS software version 24.  For assessing the rate of effective factors, the GEE (Generalized estimating Equation) methods were used.
Results: According to the results, the mean SPL was 63.30 ± 7.33 dB and a significant difference was observed between the mean SPL and the standard (35 dB) (p <0.001). Moreover, the highest mean of sound in hospitals was observed in Fatemeh Al-Zahra Hospital. Considering the week days, Saturday and among shifts, the night shift had the highest mean SPL.
Conclusion: The findings showed that SPL was higher than the Iranian National Construction Regulations and World Health Organization (WHO) standards in all evaluated places. So, the noise control programs should be considered seriously.

Authors: Syaripudin Tatang
Published: April 2020

This paper aims to describe multiliteration and higher order thinking skills (HOTS) as challenges for 21st century society, as well as their implications to education. 21st century civilization has triggered the development of the meaning of literacy into multiliteration, and requires the public to have cognitive process skills that are classified as higher order thinking skills. Based on analysis of implications, multiliteration and higher order ranking skills have implications to education. Especially in developing thinking process skills, the purpose of education should be directed at developing cognitive process skills at levels C2 through C6. The curriculum is ideally holistic, integrative, child centered and activity centered. The learning approach is student-centered and applies heuristic strategies. In its implementation, it is necessary to apply various models and/or learning methods that require students to do problem solving, think creatively, and cooperate. The teacher acts as a guide and facilitator rather than as an instructor. 21st century teachers ideally have characteristics: permissive, friendly, a guide, open-minded, enthusiastic, creative, socially aware, alert, patient, cooperative and sincere.

Published: April 2020

Literacy is one of life skills that cannot be separated from an individual. Starting from the low literacy ability of elementary school students in Indonesia, especially the ability to read, researchers try to find alternatives that can help students in making literacy activities into fun activities. One of the causes of the low literacy in Indonesia is the difficulty in obtaining fun teaching materials, so that students have assumed that literacy is only limited to school assignments. One of the efforts that the writer did was to use literacy-based teaching materials. The purpose of this study is to find out how the application of literacy-based teaching materials especially big books and whether literacy-based teaching materials can improve students' reading skills. In addition, teachers are expected to be able to make improvements in planning and implementation of learning activities and researchers are expected to be able to collaborate with practitioners in the field, thereby increasing insight and input for teaching in LPTK. This study uses a quantitative approach. The results showed that big books can improve students' reading skills in elementary school.

Authors: Andriansyah Eka Hendi
Published: April 2020

The purpose of this study is to create the formation of students' attitudes and understanding of teaching materials through a contextual approach by comparing the use of two methods that are almost the same, namely the demonstration method and the field trip method. The contextual approach is very compatible with the 2013 curriculum, in which students are required to be able to construct their learning through an approach by leading to real-world learning. The research method used is the experimental method that tests the use of two learning methods that exist in contextual learning, namely the control class treatment with the Demonstration method and the experimental class treatment with the field trip method. It was found the significance of the differences in learning by using a contextual approach, especially using the field trip method compared to using a contextual approach with a demonstration method. Learning done with field trips results in higher scores in terms of understanding as well as student attitudes compared to demonstration methods on the same contextual approach. Bringing students directly into the real world while providing students the opportunity to socialize with the world around them and learn to interact in the right way so that they can create better attitudes than learning in the classroom.

Effect of Alcohols on the Rheological Properties of Tetrahydrofuran Hydrate Slurries
Authors: de Lima Silva Paulo H. , Naccache Mônica F. , de Souza Mendes Paulo R. , Valim Leandro S. , Teixeira Adriana
Published: April 2020

Hydrate formation is an issue that can have a significant negative economic impact on the oil industry. Hydrates are crystalline solids that resemble ice, usually formed in the presence of a mixture of oil/gas/water in conditions of high pressure and low temperature, similar to those found in deepwater oil production. Depending on the amount of hydrates formed, production lines can be severely affected, causing huge financial losses. Therefore, it is of great interest to understand and analyze the characteristics of the hydrates formed, and eventually identify means of mitigating hydrate formation, to reduce the production losses. In this work we analyze the effect of alcohols for hydrate mitigation through rheological characterization. We study the rheology of hydrates formed in a mixture of tetrahydrofuran (THF) and water. This is used as a model system because hydrates are formed at atmospheric pressure. Using the rheology of the model system as a baseline case, we analyze the effect of different alcohols (monoethylene glycol, ethanol, isopropanol) and concentrations on the rheology of the resulting hydrate slurries to verify and understand the capability of these additives to mitigate hydrate formation.

Background: Despite the beneficial health effects of exclusive breastfeeding (EBF) for infants, the practice of EBF remains low in South Africa, a country burdened with HIV. Given that the factors limiting EBF are multi-factorial and context-specific, we sought to examine the factors influencing EBF practice among mothers on antiretroviral therapy (ART) in the Eastern Cape, South Africa.Methods: This was a prospective cross-sectional study of 469 parturient women enlisted in the prevention of mother-to-child HIV transmission cohort study in the Eastern Cape. A structured questionnaire was used to collect relevant socio-demographic, lifestyle and maternal information. Bivariate and multivariate logistic regression analyses were performed to assess associations between socio-demographic, lifestyle factors and EBF.Results: EBF for six months was practised by a few women (32.0%). The prevalence of EBF was significantly higher among married women (36.8%), unemployed women (36.6%), non-smokers (32.7%), and those who never drank alcohol (37.0%). Unemployed women (AOR = 1.66, 95% CI: 1.08-2.56) and those with grade 12 or less level of education (AOR =2.76, 95% CI: 1.02-7.49) had a higher likelihood of practising EBF for six months compared to employed women and women who attained tertiary level of education. While mothers who take alcohol (AOR = 0.54, 95% CI: 0.34-0.85) were less likely to practice EBF for six months compared to those who never drank alcohol. Conclusions: Factors contributing to the low prevalence of EBF among mothers in this setting are employment, tertiary education and alcohol consumption. Strategies should target these socioeconomic indicators and lifestyle behaviour in the region.
A study on the design of a wardrobe, for patients bed-ridden with cancer, applying the knowledge of anonymous design
Authors: Fujii Naoko
Published: April 2020

The majority of human beings will be admitted to hospital at some point over the course of their lives. For the more fortunate among us, these hospital stays will be brief and will barely register as a significant experience. However, for others, being admitted for weeks or months at
a time will be necessary in order to combat and recover from whatever it was that made admittance to hospital necessary. While it is easy to think of many reasons why a prolonged hospital stay might be undesirable, one that may escape our attention is the clothes that are worn by patients
during their stay. Once a patient has been assigned a bed, they are often given a gown which they put on without thought and then lie down. The gowns that are given to patients are generally designed with healthcare professionals in mind. For example, in Japan pyjamas and yukata (bathrobes)
are used as hospital gowns because they have a front opening that is easy to use during treatment and nursing care. In addition, the other gowns can be opened from the ankle to the crotch using the zip. Dr Naoko Fujii has focused her career on designing clothes for hospital patients and believes
that there is a way to satisfy the practical needs of a hospital and the care it gives at the same time as satisfying the requirements of patients. She is now focusing her attention on this challenge.

Published: April 2020

Metallurgy is part of materials science and engineering and refers to the study of the physical and chemical behaviour of metallic elements, their intermetallic compounds, and their mixtures, known as alloys. It's an exciting area, with metals, alloys and composites representing the
backbone of many industries, including construction, automotive and aerospace. One important element, which has widespread uses in a number of industries due to its ability to be used in the fabrication of lightweight materials, is magnesium (Mg). It is particularly useful when alloyed with
other elements and processed properly to make it lighter, stronger, and more compelling in airplane and car construction. In order for innovations to arise in this field, enhanced understanding of alloys is required, and this is something that Professors Yoshihito Kawamura and Donald Shih,
researchers at the Magnesium Research Center (MRC), Kumamoto University, Japan, are focused on.

Published: April 2020

It is difficult now to imagine life without dependence on a multitude of electronic devices that permeate our day-to-day endeavours. Most of these devices depend on a number of factors, one of which is the phenomenon of piezoresistance. Professor Kazunori Matsuda, a researcher in microelectronics
and semiconductor engineering in the Department of Nano Material and Bio Engineering at Tokushima Bunri University, is leading a team which has been working on the piezoresistance effect and the established theoretical model for silicon. Matsuda's project objective is to verify the piezoresistance
effect of germanium both experimentally and theoretically. The team hopes that their results will provide a breakthrough into research in the current semiconductor physics.

EPISTEMOLOGIAS DA GAMIFICAÇÃO NA EDUCAÇÃO: TEORIAS DE APRENDIZAGEM EM EVIDÊNCIA
Authors: Oliveira Josefa Kelly Cavalcante de , Pimentel Fernando Silvio Cavalcante
Published: April 2020

O artigo está vinculado à pesquisa Gamificação na Perspectiva dos Multiletramentos, desenvolvida nos anos iniciais do Ensino Fundamental. Tem como objetivo analisar as epistemologias presentes na literatura sobre gamificação. A pesquisa foi realizada com base em revisão sistemática de literatura, conforme os princípios propostos por Yin (2016). O presente trabalho baseou-se no tema de estudo, problema da pesquisa, resumo, palavras-chave, introdução, principais resultados e considerações para análise de dados das dissertações, e como critério de seleção a gamificação na educação. Nesse contexto, as questões epistemológicas são relevantes, na medida em que são elas que estabelecem os critérios que são levados em consideração nas estratégias de gamificação na educação para justificar o caminho proposto para o desenvolvimento da aprendizagem do estudante. Todavia, nem sempre estão alicerçadas em fundamentos que vão além do sendo comum, ou ainda são baseadas em uma perspectiva que contempla a gamificação como ferramenta, instrumento para utilização. Esta pesquisa foi realizada com o apoio financeiro da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes) no Brasil.
PERSPECTIVAS DA FORMAÇÃO DE PROFESSORES PARA O MAGISTÉRIO NA EDUCAÇÃO BÁSICA: A RELAÇÃO TEORIA E PRÁTICA E O LUGAR DAS PRÁTICAS
Authors: Gatti Bernardete A.
Published: April 2020

Neste artigo analisamos questões relativas ao conceito de prática educacional e suas relações com as teorias, a partir de onde levantamos questões sobre as práticas desenvolvidas na formação para a docência na educação básica, seja em processos de educação continuada, seja em processos de formação inicial no ensino superior. A discussão parte da descrição de dois exemplos concretos realizados, um em escolas municipais de São Paulo, outro em uma Universidade Federal, em Niterói, a partir da utilização de publicações. Agregase estes exemplos de referências a várias outras iniciativas. Pelo examinado, considerando o universo possível para mudar e renovar perspectivas nessas formações, constata-se que as iniciativas ainda são tímidas: de um lado, não têm afetado substancialmente os currículos institucionais de formação para a docência em suas dinâmicas e práticas; de outro, nas formações continuadas ainda não alcançaram largo curso. No entanto, são reveladoras da consciência da necessidade de mudar práticas educacionais para essas formações e se mostram como alternativas pedagógicas ao hábito instaurado nos cursos de formação para a docência.

Authors: Miranda Nonato Assis , Garcia Paulo Sérgio , Veraszto Estéfano Vizconde
Published: April 2020

No contexto das políticas de avaliação em larga escala, este artigo apresenta os resultados de um estudo que investigou as concepções de gestores escolares acerca do uso dos resultados dessa avaliação na rede pública paulista de ensino. Os dados foram coletados por meio de um questionário estruturado e tratados pelo método da Análise Fatorial. As concepções dos gestores mostram a importância das avaliações em larga escala no desenvolvimento de práticas de gestão que estão atreladas às dimensões pedagógica e de monitoramento do currículo, sendo o pagamento do bônus um incentivo à melhoria dos resultados educacionais. Conclui-se que essas concepções apontam para o alinhamento entre o preconizado pelas políticas educativas paulistas e um modelo de avaliação que se tornou um instrumento de auditoria orientado para a obtenção de dados com vistas à definição de políticas e orientação da gestão escolar.
Usability of Mobile Health Apps for Postoperative Care: Systematic Review (Preprint)
Authors: Patel Ben , Thind Arron
Published: April 2020

BACKGROUND

Mobile health (mHealth) apps are increasingly used postoperatively to monitor, educate, and rehabilitate. The usability of mHealth apps is critical to their implementation.

OBJECTIVE

This systematic review evaluates the (1) methodology of usability analyses, (2) domains of usability being assessed, and (3) results of usability analyses.

METHODS

The A Measurement Tool to Assess Systematic Reviews checklist was consulted. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guideline was adhered to. Screening was undertaken by 2 independent reviewers. All included studies were assessed for risk of bias. Domains of usability were compared with the gold-standard mHealth App Usability Questionnaire (MAUQ).

RESULTS

A total of 33 of 720 identified studies were included for data extraction. Of the 5 included randomized controlled trials (RCTs), usability was never the primary end point. Methodology of usability analyses included interview (10/33), self-created questionnaire (18/33), and validated questionnaire (9/33). Of the 3 domains of usability proposed in the MAUQ, satisfaction was assessed in 28 of the 33 studies, system information arrangement was assessed in 11 of the 33 studies, and usefulness was assessed in 18 of the 33 studies. Usability of mHealth apps was above industry average, with median System Usability Scale scores ranging from 76 to 95 out of 100.

CONCLUSIONS

Current analyses of mHealth app usability are substandard. RCTs are rare, and validated questionnaires are infrequently consulted. Of the 3 domains of usability, only satisfaction is regularly assessed. There is significant bias throughout the literature, particularly with regards to conflicts of interest. Future studies should adhere to the MAUQ to assess usability and improve the utility of mHealth apps.
