Feasibility of using waste sweet bay wood (Laurus nobilis L.) in particleboard production
Authors: Yazici Hikmet
Published: July 2021

Turkey holds a 95% market share of global sweet bay (Laurus nobilis L.) leaf trade, and it has 25 leaf processing and manufacturing facilities with different capacities. In this study, the usability of waste sweet bay wood (BW) that was removed from bay leaf processing plants was studied. For this purpose, three-layer particleboards were produced by mixing industrial chips (IC) and waste sweet bay wood chips (BWC) at a mixture rate of 0%, 25%, 50%, 75%, and 100%. For panel production, urea formaldehyde adhesive (UF) was used in 10% of the surface layers and in 8% of the middle layer based on dry chip weight. Some mechanical properties, such as bending strength (BS), modulus of elasticity in bending (MOE), internal bond strength (IB) of the test panels, thickness swelling (TS), and water absorption (WA) amounts, were determined. The results showed that all panel groups except group C (25% BWC + 75% IC) met the general purpose panel class (P1) requirements for use in dry conditions according to TS EN 312 (2012). In addition, group A panels (100% BWC) met the requirements of P2 class for the MOE and BS, and group E panels (75% BWC + 25% IC) met the P3 standards. The results showed that BWC could be used to produce particleboard for general purposes, including furniture.

Published: July 2021

The surface roughness of bamboo is a factor that determines the processing quality. The effects of spindle speed, feed speed, and cutting depth on the surface roughness of bamboo were studied using the orthogonal design test method. The results were analyzed using range analysis, main effect analysis, interaction analysis, and variance analysis to determine the effect of cutting parameters on the surface roughness of bamboo. The feed speed had a greater effect on the surface roughness of the bamboo in the tangential section; the spindle speed had a greater impact on the surface roughness of the bamboo in the cross section. The cutting depth had a greater impact on the surface roughness of the bamboo in the radial section. For the surface roughness on the tangential, cross, and radial sections of the bamboo, there was a relationship with the cutting parameters. A mathematical model for the analysis of surface roughness was established by response surface method. Also, contour and surface plots based on regression models showed the correlation between surface roughness and all possible pairwise combinations of three cutting parameter variables. The cutting technology with the best surface quality was determined by optimization analysis.
Determination of decay, larvae resistance, water uptake, color, and hardness properties of wood impregnated with honeybee wax
Authors: Akçay Çağlar
Published: July 2021

The aim of the study was to determine the effect of honeybee wax impregnation on the antifungal, larvicidal, water uptake, color, and mechanical properties of wood. Wood samples (poplar, Scots pine, beech, and lime) were impregnated with melted honeybee wax under vacuum. The wax-impregnated samples were exposed to the wood-decay fungi Trametes versicolor and Neolentinus lepideus for 8 weeks. The larvicidal effect of the beeswax was tested against European old house borer (Hylotrupes bajulus L.). Water uptake, color measurements, and surface hardness were also tested. According to the obtained findings, a 34.6% mass loss was seen in the poplar control wood, and only 3.9% mass loss was found in the 100% beeswax-impregnated samples. The results showed that H. bajulus larvae could digest honeybee wax with wood when beeswax surface treatment was applied. Additionally, an average of 30% larvae mortality rate was achieved on beeswax-treated wood surfaces, compared to a 2.5% rate on the controls. However, when wood was deeply treated with beeswax, larval mortality reached 100%. In the water uptake test, beeswax-treated samples showed water repellent efficiency. The lowest water uptake (24.2%) was obtained in poplar wood treated with 100% beeswax, compared to 92.6% in the poplar control in 96 h immersion time. With the beeswax treatment, a* and b* color values increased, while the L* values decreased.

Published: July 2021

Cross-laminated timber (CLT) is increasingly used in building construction worldwide. Durability of CLT against fungal attack has yet to be fully explored. Water intrusion in mass timber can yield dimensional changes and microbial growth. This study evaluated the performance of CLT coated with various water- and solvent-based stains commercially available in the United States. Twelve coatings were tested for moisture excluding effectiveness, water repellency effectiveness, volumetric swelling, and anti-swelling efficiency. Only five coatings repelled water, limiting dimensional changes. A modified version of AWPA E10-16 (2016) was performed to evaluate decay of the coated CLT samples. Weight losses were recorded after 18 weeks’ exposure to the brown-rot decay fungus Gloeophyllum trabeum. In accelerated mold testing, coated CLT samples were grown in chambers containing spores of Aspergillus sp., Rhizopus sp., and Penicillium sp. for 29 d and assessed visually for mold growth. In both tests, coating C (transparent, water-based, alkyd/acrylic resin) performed the best among the tested coatings. Mold growth was completely prevented, and weight loss caused by G. trabeum was approximately 1.33%. Although coating C prevented decay for 18 weeks, coatings are not intended to protect against decay fungi. However, they may offer short-term protection during transport, storage, and construction.

What Was Protected by the State in Vilnius and Nowogródek Voivodeships Between 1928 and 1939? Evaluation and Listing of Cultural Monuments
Authors: Kurienė Viktorija
Published: July 2021

This article focuses on the process of monument listing, done by conservators of Vilnius in interwar Poland and which provided the monuments state protection. Between 1931 and 1939, monument conservators made 202 decisions confirming monumental value to various objects of architecture, urbanistics, archeology and nature. In the text the listing and evaluation process is described by analyzing the register of monuments and the decisions it was based on. The documents from the archive of the Art Department of Vilnius voivodeship are used in the article. The analysis of the register of monuments is based on statistical methods. Interpretation and evaluation are based on analytical and comparative methods. The research leads to findings that monument listing was dominated by architecture. Objects of nature were announced monuments based on their cultural value. Officially the status of a monument was given on the grounds of its aesthetics, age or documental value. However, the inner motive was Polishness. Thus, the most frequent monuments were baroque Catholic churches. The patriotic context is also seen in nature protection. The process of monument listing was led by only one expert – a conservator of monuments. The monument status and state protection depended on their interests, expertise and power. The conservator cooperated only with a small group of Polish authority and intelligentsia, leaving the majority of society out of this heritage process. The decision confirming monumental value was a way to control and have an impact directly on the monument’s existence, indirectly – on the discourse of memory. The monument listing reveals values and identities of a Polish art historian working for the state. Consequently, these values and identities were projected for the whole society as universal. This type of discourse on heritage, conception and practice was common in Western countries in the 20th c.
In Defense of Alexander Ivanovich Isaev (Using Materials of the State Archive of the Tomsk Region)
Authors: Trukhan Elena
Published: July 2021

The article introduces into scientific circulation official documents dated 1853‒1855, preserved in the State Archive of the Tomsk region and recreating the last months of the life of Alexander Ivanovich Isaev — a friend of F. M. Dostoevsky in Semipalatinsk, the first husband of Maria Dmitrievna Constant (Isaeva, Dostoevskaya). These documents include: A. I. Isaev's certificate of service, issued on September 27, 1853, and 6 reports and 12 official letters dated February‒November 1855. Until recently, the corpus of biographical literature about Dostoevsky offered an image of A. I. Isaev as a bitter drunkard, a weak-willed man who ruined his career and life and left his family in poverty. Materials of the State Archive of the Tomsk region contain positive characteristics of Isaev and confirm his professional achievements and career growth from 1840 to July 28, 1853, the day of his dismissal. These archival materials reveal an important fact — the official reason for his dismissal from service. It was not Isaev's alcoholism, exaggerated in the works of Dostoevsky's biographers, but a deadly disease, namely, consumption (tuberculosis). This fact explains the words of Dostoevsky in a letter to Baron A. E. Wrangel dated August 14, 1855. about Isaev’s “dark fate”, the writer's unwavering respect and goodwill towards him, as well as the desire to raise his son Pavel as if he was Dostoevsky’s own. Archival materials demonstrate that immediately after the Isaev's death on August 4 (16), 1855, many persons applied for his position as a tavern assessor in the Kuznetsk Zemsky court, but relinquished it soon after starting the job.
Dostoevsky and Antiquity: Classical Education at the L. I. Chermak Boarding School
Authors:   Petrozavodsk State University, Smirnova Ekaterina
Published: July 2021

The article attempts to identify the classical linguistic and cultural context of F. M. Dostoevsky's education at the L. I. Chermak boarding school. It lists the programs and textbooks that Dostoevsky studied in 1834‒1837 to learn about the intricacies of classical languages and ancient history, and the teachers who may have influenced his perception of ancient history and culture. Using the issues of the “Biblioteka dlya chteniya” (Library for Reading) journal, the authors investigate which texts related to classical antiquity were available to Dostoevsky outside of the curriculum. The period of Dostoevsky's studies at the Chermak boarding school can be characterized as extremely favorable for the assimilation and comprehension of ancient heritage. The reason for this is the emphasis on classical languages in education set by government decisions, successfully augmented by the brilliant teaching staff at the boarding school, i. e., K. M. Romanovsky, N. I. Bilevich and A. M. Kubarev, Dostoevsky saw Greco-Roman antiquity not as a boring and tiresome collection of dead forms, but as a source of fantasies, reflections, comparisons, and sublime ideas. The publications in Library for Reading on history and archeology, literature and art of Ancient Greece and Rome revealed antiquity in a multi-faceted manner, taking the teenager inclined to serious reading far beyond the school curriculum into the world of stunning discoveries, sharp scientific controversy, bold comparisons with modern times and vivid artistic images.

Currently, in various industries (engineering, aircraft, energy, etc.) the issue of product quality assurance and control is particularly acute. This is due primarily to the ever-increasing requirements for increasing reliability with increasing loads on products, which entails the strengthening of technical standards. The issue of quality control for rocket and space technology products is especially relevant. Modern power structures of rocket and spacecraft made of polymer composite materials, and especially the body of solid fuel rocket engines (SFRЕ), are multilayer packages of various polymer-composite materials (PKM), obtained and interconnected in the process of manufacturing the body. The efficiency of SFRЕ depends on the quality of the formation of PKM in production conditions. The most important issues are the implementation of production quality control of composite structures, the reliability of control results and the ability to automate the control process. The article presents an automated system of non-contact ultrasonic non-destructive testing, which allows to control the stability of the technological process of forming the composite material of the wall of the SFRЕ body and, if necessary, to adjust it. The probability of detecting zones of anomalous violation of the integrity of the wall material of the SFRЕ housing is carried out due to adaptive algorithms, digital systems of multilevel matrix processing and optimal filtering of the received signals. The automated system of contactless ultrasonic non-destructive quality control of SFRЕ cases allows to register conditions of scanning and control for more visual representation of the defectogram in the expanded look of the case of a product in the course of control and at documentation of its results. The presented results of work on the development of an automated system of non-destructive testing of the integrity of the buildings of the SFRЕ type "cocoon" confirm the possibilities of practical implementation in production.

During the decade of research, the Research Institute “Mykolaiv Astronomical Observatory” (RI “MAO”) developed hardware and software for monitoring, extracting, and calculating the parameters of meteor phenomena using the forward scattering by meteor ionized trail of the signals of over-the-horizon FM-stations broadcasted in the frequency range of 88—108 MHz. This allowed creating a network of observations of meteor phenomena in the radio range, which consists of six stations located in Mykolaiv (three stations), Rivne, Lviv, and Hlukhiv. The stations have identical hardware and software. Yagi-Uda antennas with six or eight horizontal vibrators and SDR receivers based at RTR2832U microchip are used to receive radio signals. The station software performs continuous registration and analysis of received radio signals at the output of quadrature detectors of the receivers, automatic detection of moments of appearances of meteor reflections, formation, and sending by e-mail daily reports on detected meteor phenomena. Equipment setup and current monitoring of stations operations are carried out by the RI «MAO» using remote access to station computers via the Internet. Monthly reports on the number of meteor events recorded by each station are posted on the site of Radio Meteor Observation Bulletin (RMOB). The article presents the results, obtained by the network in 2017—2019, confirming a correspondence of daily variations in the number of meteors registered by network stations, to the known dependence (observation of meteors in the apex and antapex), as well as a correspondence between the expected characteristics (in time and intensity) of three meteor showers (Perseids, Geminids and Quadrantids) and that had been obtained by the network. Recommendations are also given in the article for additional research aimed at achieving the main goal, namely, expanding information about meteor phenomena, including the estimating of kinematic parameters (velocities, radiants) of meteoroids and their relationship with potentially hazardous asteroids.

Published: July 2021

Introduction. Insects act as an element of the mythological system and rituals, provided by a variety of functions, occupied a certain place in the rituals, beliefs and medical practice of the Karelians. Among domestic insect parasites, the lice are most widely represented in the Karelian language and rituals. The research novelty of the study is determined by the fact that researchers did not turn to the question of the functioning of insects in mythological views and the ritual tradition of Karelians. However, such research is necessary in order to recreate the integrity of the mythological picture of the Karelians, which determines the relevance of this article.
Materials and Methods. The material for the study was entomological images in the beliefs and folk medicine of the Karelians. They were considered using comparative historical, comparative and comparative and ethnolinguistic methods.
Results and Discussion. The authors dwell on the mythological views of Karelians about domestic parasite insects using the example of lice. These beliefs are reflected in the causes of diseases, methods of treatment, as well as in mythological stories and folklore.
Conclusion. The collected and analyzed linguistic and ethnographic data make it possible to come to the conclusion that the lice are the representatives of the entomofauna. Karelians have many beliefs connected with lice, which are reflected in the linguistic picture of the world and traditional culture.
Los primeros juegos atléticos y la primera carrera pedestre costarricense. San José 1905
Authors: Jorge Lobo Di Palma Jorge
Published: July 2021

A finales del siglo XIX, Costa Rica experimentaba un proyecto cultural propuesto por los liberales de la época en el cual se buscaba crear una identidad nacional moderna e influenciada, en gran medida, por aquellos intelectuales costarricense que estudiaron en Europa y que volvían con ambiciosos proyectos de modernización, entre los que se incluían la práctica deportiva. Por lo que el objetivo de la presente semblanza histórica es rescatar, como parte de la memoria del deporte costarricense, los primeros juegos atléticos celebrados en el país a principios del siglo XX. La actividad contempló 14 eventos en los que se incluyen pruebas de pista, campo y, además, la primera prueba pedestre registrada. Para la realización de dicho evento, se llegó a construir la primera pista atlética del país, en la Sabana, lo cual dejó un legado permanente hasta el día de hoy. Fueron unos juegos tan bien organizados, que estaba incluida la participación de las mujeres. Algunas de esas pruebas, todavía hoy en día están vigentes a nivel nacional e internacional, por lo que permitiría continuar con investigaciones sobre evolución técnica e histórica del atletismo en Costa Rica.

Profesorado de educación primaria con mención en Chile: entre lo planteado en los estándares orientadores para egresados de pedagogía y lo real de la práctica docente
Authors: Sanchez Bustos Mario Arturo , Torres Díaz Romi Alejandra
Published: July 2021

En el contexto de un Sistema Nacional de Aseguramiento de Calidad en educación, que exige precisión en la definición de los aprendizajes del currículo nacional; el presente estudio compara lo planteado en los estándares orientadores para personas egresadas de carreras de pedagogía en educación básica con lo que ocurre en las escuelas de primaria; ya que se asume que para cada asignatura se designarán profesionales con preparación en el área. Este artículo pretende contribuir a la reflexión sobre la formación docente y la necesidad de potenciar el trabajo en todas las disciplinas para generar aprendizajes más contextualizados y significativos, y cómo esta situación presenta una buena oportunidad para que las universidades puedan crear una especialización, post título o mención para docentes del primer ciclo básico en las áreas indicadas sin preparación. Para esta investigación se trabajó con 50 docentes y 30 directivos de escuelas subvencionadas; además, se revisó la oferta académica de 28 universidades que dictan esta carrera en Chile. Los resultados evidencian que no existe una relación entre la práctica y la formación profesional en una mención específica, porque en realidad las y los docentes imparten clases también en otras disciplinas como Artes Visuales, Música o Tecnología, independiente si recibieron o no preparación en ellas, y en consecuencia, al no tener certeza del dominio que posee el profesorado sobre estas áreas del conocimiento, no se puede garantizar que la formación que reciban sus estudiantes sea de calidad, lo que demanda que las escuelas formadoras de docentes pongan un acento especial en la necesidad de impartir menciones en todas las asignaturas impuestas como obligatorias.

Published: July 2021

Este trabajo es un reporte parcial de una investigación en proceso, que corresponde al diseño de un taller con enfoque en aprendizaje colaborativo para resignificar el concepto y las implicaciones del trabajo colegiado en profesores de una Institución Formadora de Docentes en Durango, México. Se realizó bajo la metodología cualitativa, siguiendo el método de la Investigación-Acción, tipo práctico-deliberativo y el modelo de Elliott (1993, citado por Latorre, 2003). Para diagnosticar el problema, en la recogida de datos se utilizó la técnica de encuesta mediante la aplicación de un cuestionario de respuesta abierta a 17 docentes. Para sistematizar y validar la información se siguió el modelo de Cisterna (2005) de categorización y triangulación. Los resultados corresponden a la fase de diagnóstico y el diseño de una propuesta de intervención en función de dos categorías: conceptos e implicaciones. Como principales hallazgos se identifica que existe un sentido latente sobre el trabajo colegiado y sus implicaciones, asociado a la racionalidad técnica y competitiva. En el diseño de la propuesta se conjugan datos empíricos y teóricos, además comprende niveles de conocimiento que van desde lo epistemológico hasta lo didáctico. Se concluye que existe entre el profesorado concepciones diversificadas sobre el trabajo colegiado y sus implicaciones en el desarrollo de las actividades institucionales, que pueden ser resignificadas a partir de la instrumentación de estrategias de aprendizaje colaborativo.

Published: July 2021

This study is aimed at understanding perceptions regarding how physical activity impacts women who are participating in the Mothers in Movement program an initiative sponsored by two priority schools in Heredia, Costa Rica and also examines social support received by participants and their families. The goal was to obtain input to foster interventions towards increasing physical activity among sedentary adult women and their families. This study uses a qualitative approach, obtaining data through focus groups conducted among a sample of 22 persons who are stay-at-home mothers. The study results show that, at an intrapersonal level, women feel more successful and self-sufficient when they are physically active. They are also better able to control their expectations as well as their social, persuasion and modelling abilities.  On an interpersonal level, participants turned to social, instrumental, emotional and informational support and companionship when deciding to engage in physical activity. Finally, at an organizational level, the school´s support in helping coordinate and execute this project was essential to promoting physical activity. This study highlighted the success of a socio-ecological model as a starting point to help sedentary mothers and their families lead more physically active lives.

El presente artículo tiene como objetivo analizar la percepción de estudiantes de tercer año medio, de un establecimiento educacional de la provincia de Concepción hacia distintos tipos de retroalimentación o feedback correctivo oral en errores de pronunciación. La metodología utilizada se basa en el enfoque de investigación cualitativa de paradigma interpretativo bajo un diseño de estudio de caso. La muestra estuvo constituida por 18 estudiantes de tercer año medio, a quienes se les aplicó una entrevista semiestructurada e individual. Mediante el análisis del contenido se obtuvo que las personas consideran al feedback como un aspecto favorable para su aprendizaje, particularmente para mejorar su pronunciación. Ellos y ellas se inclinan por la modalidad implícita de corrección y prefieren la estrategia de feedback de tipo pista metalingüística. Además, consideran que el mejor momento para recibir este feedback es inmediatamente finalizada la tarea oral. Este estudio busca resaltar la importancia del Feedback Correctivo Oral y su beneficio en aspectos de la oralidad, como en la pronunciación del estudiantado que aprende inglés como lengua extranjera.

Tres objetivos guiaron el trabajo: examinar el impacto de la crisis económica en el financiamiento y gasto público en educación en el Perú, 2020-2021; revisar lo actuado en financiamiento y gasto educativo, 1950-2019; y demostrar los beneficios para el país del desarrollo humano junto a las competencias para la vida. Para lograr los dos primeros objetivos, el diseño es no experimental, longitudinal y de tendencia; y el tercer objetivo, transversal. Los datos, en el caso de las finanzas educativas y el PBI del Perú, corresponden al período 1950-2019; las competencias para la vida (años 2012, 2015 y 2018) y los indicadores de educación, salud, economía y social, recolectados de 55 países, durante 2018 o 2019. Las fuentes de información fueron nacionales e internacionales de reconocido prestigio. El tratamiento de los datos se basó en el uso de técnicas estadísticas inferenciales: mínimos cuadrados ordinarios, test de Chow y correlación. Los resultados de la investigación evidencian lo siguiente: primero, las proyecciones revelan una contracción del gasto público en educación al finalizar 2020 y un crecimiento a 2021; segundo, la tensión por definir la fuente (pública o privada) de financiamiento de la educación, el uso del gasto educativo público como instrumento de política económica y superposición, desde 2001, de las competencias para la vida sobre la tasa de escolaridad; y tercero, a partir de la evidencia internacional, los beneficios de las competencias para la vida en el enfoque escuela eficaz. Finalmente, las recomendaciones se formulan para cada conclusión.

Objetivo: compreender as implicações biopsicossociais em vítimas de acidentes de trânsito que adquiriram deficiência. Método: Trata-se de uma pesquisa descritiva com abordagem qualitativa, desenvolvida em um Centro de Saúde Universitário de um município de referência do Território Sertão Produtivo da Bahia, Brasil, com doze vítimas de acidentes de trânsito atendidas com deficiência adquirida. As informações foram coletadas por meio de entrevista semiestruturada, no período de agosto a setembro de 2018. Para a análise das informações, foi utilizada a técnica de análise de conteúdo. Resultados: No aspecto físico, o acidente de trânsito gerou restrição de autonomia, limitação física para realização de atividades básicas da vida diária, deterioração de habilidades e perda da independência. No aspecto psicológico, o acidente causou sofrimento psíquico, representado por sentimentos de desesperança, tristeza, estresse, raiva, culpa e medo, intensificados pela instabilidade econômica. Além disso, o acidente teve grande impacto social, como restrições ao trabalho, estudo e lazer. Conclusão: a deficiência adquirida em um acidente de trânsito tem repercussões importantes na vida das vítimas, tanto física quanto psicossocialmente. A formação de redes de apoio compostas por familiares e equipe de saúde é fundamental para dar o suporte necessário às pessoas nesta nova condição de vida
A enfermagem brasileira pede socorro

O presente ensaio visa refletir e incrementar a divulgação sobre o atual panorama da Enfermagem brasileira com vistas à sensibilização da sociedade, órgãos, entidades e categoria profissional. O presente ensaio foi desenvolvido por meio de análise de artigos e documentos legais selecionados de forma aleatória nas plataformas de pesquisa no intuito de sustentar teoricamente os resultados aqui discutidos. Após anos de lutas sem avanços significativos, certamente a passividade dos profissionais precisa ser reduzida e contrapor às concepções de uma Enfermagem caridosa e subserviente. Desta forma, os sujeitos envolvidos devem assumir de forma ativa e emancipatória a responsabilidade de lutar em defesa da profissão e de todos que dela se beneficiam. Sugere-se que a Enfermagem brasileira intensifique a posição político-participativa em movimentos reivindicatórios e ocupem os espaços de tomada de decisões para lutarem pela categoria. Desse modo, ocorrerá o fortalecimento da profissão que, consequentemente, culminará na sua valorização e melhores condições de trabalho, implicando de forma positiva nas ações assistenciais.

Published: July 2021

Biohumus-based preparations are widespread in agricultural production due to the high content of nutrients for plants, which improve their growth and development and, as a result, productivity. GTK indicates sufficient moisture during the growing season, but, given the nature of precipitation, in certain periods, pea plants that are sensitive to moisture, experience a lack of it in the soil and atmospheric air. The research was carried out in the farm Belousov I.V. of Starozhilovsky district. The area of plots is 40 m2. Water for the preparation of the drug solution was taken from a pond located 20 m from the pea field. The object of the study is the seed pea (Pisumsativum), which belongs to the Fabaceae family, the genus Pisum, which forms nodules on metamorphosed roots. As a result, there is a different intensity of nutrient and water consumption in ontogenesis. Watering and spraying pea plants with Humistar preparation made it possible to reliably prove high agronomic and economic efficiency in option 2: activation of enzymes, an increase in the mass of nodules on roots to 69 mg/plant, an improvement in growth to 57 cm and plant development by 5–15 days, an increase in peas yield up to 27,7 dt/ha, accumulation of dry matter in seeds up to 59 g and an increase in the level of profitability up to 80,7%.

ABSTRACT Objectives: to develop and validate an educational technology (educational video) oriented toward health professionals and addressing fall prevention in hospitalized children. Methods: methodological study carried out between December 2017 and January 2019 in five steps: identification of themes based on a literature review and the examination of the Brazilian Ministry of Health Fall Prevention Protocol; development of an educational video; validation of the material by referees specialized in children’s health, patient safety, or social communication; validation by the target audience, made up of health professionals at a pediatrics institute in Rio de Janeiro, Brazil; and material adjustment. A Likert-like scale was used to validate the video, with items showing agreement indexes equal to or higher than 70% considered validated. Results: the video “Fall prevention in hospitalized children” was produced and validated with an average adequacy agreement index of 86% among the referees and 99.3% among the target audience. Only one item, related to adequate size of titles and topics, was not validated by the referees and was modified based on their suggestions. Conclusion: the video was validated by the referees and the target audience and may have practical application in education and training of health professionals who work in the children’s health field.
