Multi-objectives robust optimization based on Grey-Taguchi method for the electric vehicle frame collision
Authors: Xie Jipeng , Yang Guolai , Zhao Zhendong , Ni Jianhua
Published: May 2021

The proportion of electric vehicles in vehicle manufacturing is increasing, but with the endurance mileage of the battery improved, the collision safety problem of electric vehicles is becoming more prominent. To solve a multi-objective robust design problem with discrete variables for vehicle collision design, we propose the Grey-Taguchi robust optimization method. The Grey-Taguchi method transforms the multi-objective functions into a single grey relation grade sequence instead of the signal-noises ratio used in Taguchi and selects the optimal combination of design variables predicted by the minimum design of experimental and the analysis of means. For the vehicle crashworthiness problem, the Grey-Taguchi method can converge to the Pareto front with several iterations. The mass of frame, maximum lateral intrusion, and peak deceleration after the optimization are decreased 14.5 %, 32.3 %, and 17.8 %, respectively. The Grey-Taguchi robust optimization method can not only enhance the robustness of the optimization design but also improve the lightweight design performance and crashworthiness. The proposed method is considered promising for complex engineering design problems with multi-objectives and discrete design variables.
A noval risk assessment method and application for the on-site power operations
Authors: Peng Boya , Zhang Wei , Lin Xiangyu , Qiu Hao
Published: May 2021

In order to improve the risk warning and management ability of power industry workers to implement an on-site power operation, this paper proposes a new risk assessment method based on a fuzzy comprehensive assessment method with variable weight. This method begins with selecting the factors related to the risk assessment of on-site power operations. And then, the Analytic Hierarchy Process (AHP) method is used to determine the initial value of the relative weight of the risk assessment factors. Afterward, according to the actual on-site power operation situation, the score value of the risk assessment factors can be obtained. This paper innovatively proposed a variable weight mechanism, which redistributes the relative weight of risk assessment factors according to the scores of risk assessment factors. And through the membership function to determine the fuzzy judgment risk matrix to obtain the risk level of power operations. Finally, take the actual on-site power operation of “220 kV line protection inspection of a power department” as an example. Comparing the evaluation strategy of this paper with the traditional evaluation strategy, we can concluded that the evaluation strategy of this paper not only can obtain the risk level of electric power operation directly, but also can judge whether there are potential high-risk factors in the electric operation through the degree of medium-risk or high-risk membership.

Authors: Choudhary Neelam , Strelnikova Elena
Published: May 2021

In the paper, the vibrations of liquid in a rigid and circular cylindrical container have been investigated. The effects of an elastic membrane placed on the free surface of the fluid have been analyzed on sloshing frequencies. The cylindrical container is assumed to be partially filled with an incompressible fluid. The potential theory is used to formulate the mathematical problem and set up the boundary value problem. The solutions are obtained for velocity potential and the deflection of elastic membrane in form of Fourier-Bessel series. The results are compared for the proposed analytical approach and BEM.

Published: May 2021

Introducción: el quiste aracnoideo es una colección benigna de fluido similar en composición al líquido cefalorraquídeo dentro de la aracnoides, circunscrita por tejido fibrovascular normal que comprime las leptomeninges que rodean el nervio óptico.
Reporte: Se describe el caso de una paciente con quiste aracnoideo de la vaina del nervio óptico con un defecto campimétrico típico de glaucoma, pero con un disco óptico sin características de glaucoma, con el fin de resaltar la necesidad de estudiar con neuroimágenes estos casos y detectar este tipo de alteraciones.
Conclusi´ón: El quiste aracnoideo de la vaina del nervio óptico es una entidad excepcional que generalmente tiene un comportamiento benigno, permaneciendo estable en el tiempo, aunque eventualmente puede producir una neuropatía óptica compresiva, afectando la agudeza o el campo visual por daño de la capa de fibras nerviosas. En el caso descrito, este daño se manifestó con un defecto de campo visual que simulaba neuropatía glaucomatosa.
Challenges of post-war policy reforms in Lebanon's water sector – lessons learned
Authors: Gharios Georges , Farajalla Nadim , El Hajj Rana
Published: May 2021

Lebanon has not been able to properly develop and benefit from its water sources. A confessional system of governance has hindered development of the sector. Laws and regulations have been developed erratically with many superseding others without the superseded laws being erased from the registry. This created a chaotic regulatory and legal environment with overlapping jurisdictions and no clear accountability mechanisms. The period before the onset of the civil war in 1975 witnessed significant progress of both infrastructure and laws and regulations related to the management of the water sector. The civil war destroyed the water sector infrastructure and emptied all regulatory control of the resources. The period of reconstruction between 1990 and 1999 witnessed the promulgation of ambitious reconstruction plans for the water sector with funding reliant on borrowing from local and external debtors. Post 1999, government reforms started creeping into the system but were often donor driven and still suffered from the same mistakes of laws overlain on top of existing laws without erasing the older material. Critically, the management of the sector is not inclusive and the beneficiaries of water services are often not heard and ignored.
Removal of Disperse Blue 56 from synthetic textile effluent using ionic flocculation

Published: May 2021

The textile industry is one of the main generators of industrial effluent due to the large volumes of water containing a wide variety of pollutants, including dyes. Thus, the present study aimed to remove the Disperse Blue 56 dye present in synthetic textile effluent using ionic flocculation through surfactant flocs produced from animal/vegetable fat, assessing the system at different surfactant concentrations and temperatures. The process kinetics, adsorption mechanism and equilibrium were evaluated. The results show that the kinetics was better described by the Elovich model when compared to pseudo-first order and pseudo-second order models, indicating that chemical adsorption occurs during the process. The study of the adsorption mechanism obtained lower outer layer diffusivities than their intra-particle counterparts, demonstrating that the dye transport to the surfactant floc is controlled through the outer layer. The Langmuir isotherm was suitable for equilibrium data and the separation factor calculated showed that the isotherm is classified as favorable. Dye removal efficiency reached 87% after 360 minutes of contact between the effluent and the surfactant flocs, indicating that ionic flocculation is an efficient alternative in the treatment of textile effluent containing disperse dye.
Development of LaxCa1-xMnO3 materials for Bezaktiv Blue removal in aqueous media
Authors: Nascimento É. V. , Garrido Pedrosa A. M. , Souza M. J. B.
Published: May 2021

In this work, mixed oxides of LaxCa1-xMnO3 perovskite type (x = 0, 0.5 and 1.0) were synthesized through modified proteic method using collagen and calcination process at 700 °C/2 h in order to remove the commercial textile dye Bezaktiv Blue S-MAX from water. Oxides were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), N2 physisorption, scanning electron microscopy (SEM) and point of zero charge (PZC) techniques while the dye only by the first two techniques. The XRD showed that perovskite monophase was obtained for x = 0.5 and 1.0. However, for x = 0, the low crystalline perovskite phase was obtained in the midst of precursor oxides. FTIR showed the adsorption process did not damage the adsorbents structure. The successful obtained materials have meso and macroporous with slit or cavity shape, rough surface and particles with varying sizes. The pseudo-second-order model was the one that best fit the kinetic data. The process must occur through electrostatic surface interactions between the adsorbent surface and the dye molecule. For the equilibrium study, Langmuir isotherm is the most suitable when using LaMnO3 adsorbent, while Freundlich isotherm was better suited when used the other two materials. The adsorbents were termally regenerated and reused five times. The best performance was exhibited by LaMnO3.

Do ensino presencial ao remoto: experiências dos docentes do bacharelado em Turismo durante a pandemia da Covid-19
Authors: Hastenreiter Silva Marina , Soares da Cruz Hastenreiter Roberto , Laborda Santos Mayra , Conceição Martins da Silva Ivan
Published: May 2021

A imposição de isolamento social decorrente da pandemia da Covid-19 desencadeou a suspensão das aulas presenciais em toda rede pública e privada de ensino no Brasil. Com isso, docentes de instituições privadas de cursos superiores presenciais de turismo se depararam com a realidade de lecionar longe da convencional sala de aula, tendo que transpor o planejamento pedagógico pautado no ensino presencial para o ensino remoto. Perante essa conjuntura, o objetivo geral desta pesquisa foi investigar as experiências desses docentes devido à implementação do ensino remoto. Quanto aos procedimentos metodológicos, adotou-se a abordagem qualitativa, tendo como instrumento de coleta de dados entrevistas semiestruturadas online com docentes de cursos presenciais de bacharelado em turismo de instituições privadas no estado do Rio de Janeiro, no período de 21 a 28 de maio de 2020. A sistematização e análise de dados ocorreu baseada na pesquisa de Estrada-Villa (2014), concomitantemente ao uso dos pressupostos de análise categorial-temática de Bardin (2011). Como resultados, identificou-se oito categorias: (1) atitude e interesse; (2) características dos estudantes; (3) política da Instituição de Ensino Superior; (4) ferramentas e recursos tecnológicos; (5) treinamento; (6) capacitação docente; (7) ambiente de trabalho e trabalho de reprodução social; (8) condições físicas e psicológicas. Logo, o ensino remoto não apenas expôs o problema da desigualdade ao acesso à tecnologia digital, mas também vários outros problemas que atingem tanto docentes quanto discentes: ambiência para estudos; saúde mental-psicológica; e falta de políticas públicas direcionadas à primeira infância para auxiliar mães e pais docentes.

Fundamentados nas premissas teórico-metodológicas dos Modelos Baseados no Uso (Bybee 2016; Goldberg 1995, 2006; Traugott & Trousdale 2013), analisamos, neste artigo, a microconstrução [deixar+de+Vinf.] dos domínios semânticos de aspecto e de polaridade. Por estarem ligadas, via elo de heterossemia (Lichetenberk 1991), em diferentes redes taxionômicas do português, mostramos que essas microconstruções se originam da construção transitiva com o verbo deixar, cujo significado central é o de afastamento. Descrevemos as singularidades das microconstruções por meio de análise diacrônica, quantitativa e qualitativa, dos parâmetros tipo de entidade semântica representada pelo sujeito da microconstrução e tipo semântico de Vinf., tendo por base dados extraídos do Corpus do Português (Davis & Ferreira 2006, 2016). Os resultados nos permitem comprovar, ao final, a hipótese de que essas microconstruções surgem via relações com outras já existentes e se abstratizam gradativamente, ao sancionarem uma maior variedade de tipos semânticos de sujeito e de Vinf..

Penelitian ini bertujuan agar 1) masyarakat mengenal Angguk Kipas 2) agar angguk kipas menjadi lebih menarik 3) agar Tari Kipas asri bisa menjadi bahan ajar di sekolah 4) agar Tari kipas asri mampu menjadi magnet generasi muda untuk berkarya. Metode penelitian yang digunakan adalah etnokoreologi, yaitu Etnokoreologi itu sendiri merupakan istilah yang masih sangat muda. Di Amerika istilah ini identik dengan dance ethnology. Sebelum ada istilah etnokoreologi, pertama-tama muncul istilah ethnochoreography atau etnokoreografi di awal tahun 1960-an. Hasil penelitian adalah Proses penciptaan karya tari Kipas Asri tentu mengalami berbagai permasalahan dan kendala yang dihadapi. Terkadang sesuatu yang telah direncanakan faktanya berbeda ketika berada di lapangan, salah satu contoh seperti kesepakatan jadwal latihan dengan pemusik, mengatur jadwal dengan pemusik tidak semudah yang direncanakan karena pemusik memiliki jadwal lain yang sama dengan jadwal latihan karya tari Kipas Aari. Banyak hal yang dialami dalam realisasi proses penciptaan yang justru lebih banyak mengajarkan tentang proses kerja kelompok dalam mencipta sebuah karya tari seperti mengatur emosi ketika para penari atau pemusik sedang bercanda gurau, atau terlambat saat datang latihan. Kata Kunci: Tari kipas asri, penciptaan, etnokoerologi KIPAS ARI DANCEThis study aims to 1) let people know Angguk Kipas 2) make Angguk Kipas more attractive 3) make Asri Fan Dance be one of the teaching material in school 4) make Asri Fan Dance become a magnet for young generations to perform. The research method used is ethochoreology, which it itself is a new term. In America this term is synonymous with dance ethnology. Before the term ethnocoreology, the term ethnochoreography or ethnocoreography first appeared in the early 1960s. The results of the study show that there are obstacles in the creation process of Kipas Asri dance. Sometimes, something that has been planned turned to be different when in the field, one of the examples is the agreement on a training schedule with musicians, arranging a schedule with musicians is not as easy as it seemed because musicians have other schedules that are similar to the Kipas Aari dance practice’s schedule. Many things are experienced in the realization of the creation process which actually teaches more about group work in creating a dance work such as controlling emotions when dancers or musicians are joking or late when coming to practice. Keywords: Kipas Ari dance, creation, ethnokoerology

Published: May 2021

En 2018, la Universidad Nacional de San Martín – T (UNSM-T) realizó la autoevaluación de sus programas de estudio, para lo cual usó una herramienta basada en Excel del Sistema Nacional de Evaluación, Acreditación y Certificación de la Calidad Educativa (SINEACE), el cual cumple estructuralmente con la matriz de evaluación, pero carece de funciones que resultan indispensables para que las escuelas profesionales puedan manejar adecuadamente sus recursos. Por otro lado, la carencia de las mismas genera incertidumbre al realizar el monitoreo. En ese sentido el objetivo fue implantar un sistema de monitoreo basado en dashboard para mejorar el seguimiento y evaluación del cumplimiento de los estándares de acreditación de los programas de estudio de la UNSM-T. Para ello se realizó un estudio descriptivo comparativo, aplicado, transversal a 60 miembros de los comités de acreditación a los que se aplicó un instrumento para medir su opinión respecto al monitoreo del cumplimiento de los estándares de acreditación en la UNSM-T, antes y después de la propuesta. Los resultados nos indican que 91.7% opina que la propuesta es buena en comparación a la propuesta en Excel. Se concluye que la propuesta permite realizar un adecuado seguimiento y evaluación del cumplimiento de los estándares de acreditación de los programas de estudio de la UNSM-T.
DETERMINANTES ECONÓMICOS - FINANCIEROS DE LA RENTABILIDAD SOBRE EL PATRIMONIO EN LAS CAJAS MUNICIPALES DE AHORRO Y CRÉDITO DEL PERÚ, PERÍODO 2010 – 2014
Authors: Aparicio Ballena Jorge Alberto
Published: May 2021

Las Cajas Municipales de Ahorro y Crédito (CMAC) han crecido en el período 2010–2014, pero no a la velocidad de años anteriores, por ejemplo, sus activos totales y sus créditos directos, crecieron en dicho periodo en 162% y 159% respectivamente. Sin embargo, este importante crecimiento se viene contrarrestando con una tendencia negativa de los principales indicadores económicos y financieros de las CMACs. En el período analizado, las rentabilidades se incrementaron en el año 2011 en la mayoría de las cajas, sin embargo en el 2012 y 2013 disminuyeron notoriamente. Llevando a establecer el objetivo de describir los principales determinantes económicos – financieros de la rentabilidad que afectan el retorno del patrimonio en las CMACs. La investigación se realizó a las 11 cajas municipales existentes, siendo esta, de tipo correlacional porque trató de establecer la relación entre los determinantes económicos – financieros de la rentabilidad de las CMACs del Perú con el patrimonio de las mismas.  De acuerdo a los resultados obtenidos, y a la significancia estadística de los parámetros a través del test de ANOVA se ha logrado comprobar la hipótesis general. Por lo que se concluye que el ratio de capital global, ratio de morosidad, ratio de eficiencia, y ratio de endeudamiento, son estadísticamente significativos para explicar la rentabilidad sobre el patrimonio de las Cajas Municipales de Ahorro y Crédito del Perú, en el período 2010 – 2014.Palabras Clave: Indicadores, Rentabilidad, Patrimonio, Determinantes Economicos-Financieros.
COMPORTAMIENTO ORGANIZACIONAL DEL DOCENTE UNIVERSITARIO ANTE EL CAMBIO INSTITUCIONAL DE LA UNIVERSIDAD POLITÉCNICA TERRITORIAL JOSÉ ANTONIO ANZOÁTEGUI (UPTJAA)

Published: May 2021

Se trata de un proyecto de investigación macro que tiene como objetivo configurar una aproximación teórica etnográfica del comportamiento organizacional en la Universidad Politécnica Territorial “José Antonio Anzoátegui” (UPTJAA). El artículo presenta los hallazgos parciales que orientan la intención investigativa de describir el comportamiento organizacional del colectivo social docente en dicho contexto universitario. El método utilizado fue el etnográfico hermenéutico, siendo empleadas las técnicas para la recolección de información la observación participante (diario de campo), el grupo focal y entrevistas en profundidad. A los efectos del presente artículo se presentan los resultados obtenidos mediante la técnica de la entrevista en profundidad realizada a ocho (8) “versionantes”. El diseño de investigación se orientó en la perspectiva metodológica cualitativa por lo que la información recolectada se sistematizó mediante el proceso de codificación y categorización de los relatos proporcionados en las entrevistas. Seguidamente se realizó una “descripción densa” o interpretativa a tres categorías principales transversales: como son: (a) Espacios introspectivos del comportamiento, (b) Actuaciones comunes y el sentido de las interrelaciones, y (c) Matices sistémicas en la dinámica comportamental. Como reflexión final se tiene que en el comportamiento de los docentes resalta el predominio excesivo de la politización y burocracia partidista, lo cual genera rechazo, aislamiento y separación entre grupos, conformado un ambiente de conformismo, de disociación institucional y de deriva gerencial e institucional hacia lo que se esperaba que este tipo de universidades impactase en el bienestar social, científico y tecnológico del territorio regional y local.

El profesor se posiciona como una figura clave en la relación familia-escuela en los primeros niveles de educación. Desde esta perspectiva, el artículo presenta los resultados de una investigación fenomenológica realizada en cuatro escuelas primarias de México. Buscó comprender la perspectiva del profesor sobre la participación de los padres en la educación y su propia participación en la relación familia-escuela. Participaron 17 profesores, su selección y el tamaño de la muestra fueron determinados por muestreo selectivo y saturación teórica. Se usó la técnica de la entrevista individual. El análisis de contenido temático se encontró que el profesor percibe la participación de los padres de diferentes maneras y grados.Su participación se reduce a informarse sobre el desempeño escolar de sus hijos y apoyar a la escuela con la organización de eventos y actividades para el mejoramiento de la infraestructura escolar. Surgen como barreras para la participación de los padres: la limitada disponibilidad de tiempo debido a los compromisos de trabajo, su bajo nivel económico y la poca importancia que se da a la educación de sus hijos. Se concluye que la participación se reduce a ser utilitaria y hay desinformación sobre qué y cómo los padres pueden participar. Es necesario promover espacios que involucren a los padres en la educación de sus hijos en un ejercicio de reconocimiento mutuo y asociación para avanzar hacia el concepto de escuela como escenario de formación para la participación social, desde su estructura y organización.

El objetivo de este texto es analizar el impacto emocional y social de la desaparición forzada de una persona, en los integrantes de su familia y sus implicaciones en la dinámica familiar. Se empleó la metodología cualitativa, desde el enfoque fenomenológico, con base en la técnica de la entrevista profunda; el estudio se realizó en Morelia Michoacán, México, con la participación de una familia (madre, padre, 3 hermanas e hija del desaparecido). Los resultados obtenidos a partir del análisis de los discursos de los participantes, permitieron establecer cinco categorías: afrontamiento del duelo, distintos tipos del duelo vivido, malestares orgánicos, estrategias familiares de recuperación, afrontamiento de la falta de apoyo legal por parte de la familia. Se encontró que la familia atraviesa por una pérdida ambigua, la cual ocasiona confusión, estrés, y que a menudo atormenta su vida cotidiana. Resulta de gran relevancia comprender que con frecuencia los familiares tienen la esperanza de que el desaparecido regrese y que, al no contar con la certeza de su situación actual, se da pie a la vivencia de la pérdida ambigua, por tanto, se dificulta el procesamiento del duelo y la reestructuración del sentido de vida. En el caso de estudio, la desaparición impactó en la dinámica familiar, ya que fortalecieron su vínculo con la intención de aminorar su dolor.

LA EDUCACIÓN TRIBUTARIA EN EL PERÚ: UNA ALTERNATIVA PARA MEJORAR EL CUMPLIMIENTO DE LAS OBLIGACIONES TRIBUTARIAS
Authors: Cárdenas Rojas Gebson Roger
Published: May 2021

En el Perú, el cumplimiento de la obligación tributaria se encuentra establecida bajo el modelo de la autodeterminación del tributo, que además implica cumplir con diversos deberes formales, cuya exigencia  puede ser coaccionada por el fisco, está coerción implica una cobranza forzosa al contribuyente por parte de la Superintendencia de Aduanas y Administración Tributaria (SUNAT) quien es la encargada de administrar los tributos y aplicar la normatividad para el control y fiscalización de la obligación tributaria. Sin embargo, a pesar de que la ley ha facultado a la Administración Tributaria realizar la fiscalización y cobranza de los tributos, la Administración no ha logrado mejorar el cumplimiento tributario, ni erradicar la evasión tributaria y el contrabando. El presente artículo, aborda el estudio de la cultura tributaria frente al incumplimiento de obligaciones tributarias. La conciencia tributaria implica que la ciudadanía comprenda el rol social de los impuestos a partir de procesos educativos, es así que, se describe la importancia de la enseñanza de la tributación desde el sistema educativo básico.
Direitos humanos em tempos de pandemia
Authors: Alves de Sousa Maria Eliane
Published: May 2021

Neste estudo propõe-se uma discussão das relações entre a pandemia de Covid-19 e as condições de vida e saúde das mulheres negras no Brasil. A defesa dos direitos humanos ecoa mais forte e torna-se mais necessária em tempos de crises, porque a dignidade da pessoa humana e a cidadania podem ser ameaçadas pelas determinações tomadas para contê-las. As mulheres negras possuem situação histórica de discriminação e exclusão social que acentuam a distância social em relação aos demais segmentos sociais. A pesquisa é bibliográfica e documental a partir dos regulamentos internacionais, de tópicos sobre a pandemia e da legislação nacional e políticas nacionais para mulheres negras. A relação entre a pandemia de Covid-19 e as condições de vida e saúde das mulheres negras no Brasil transcende os fatores meramente biológicos do corpo, porque as desigualdades de gênero, racial e classe influenciam com desvantagens acumulativas para que os impactos da doença sejam mais severos e negativos para esse grupo de mulheres.

Published: May 2021

In this study, we used an image neural network model to assess the relationship between economic growth, pollution (PM2.5, PM10, and CO2), and deaths from COVID-19 in the Hubei area (China). Data analysis, neural network analysis, and deep learning experiments were carried out to assess the relationship among COVID-19 deaths, air pollution, and economic growth in China (Hubei province, the epicenter of the COVID-19 pandemic). We collected daily data at a city level from January 20 to July 31, 2020. We used main cities in the Hubei province, with data on confirmed COVID-19 deaths, air pollution (expressed in µg/m3 as PM2.5, PM10, and CO2), and per capita economic growth. Following the most recent contributions on the relationship among air pollution, GDP, and diffusion of COVID-19, we generated an algorithm capable of identifying a neural connection among these variables. The results confirmed a strong predictive relationship for the Hubei area between changes in the economic growth, fine particles, and deaths from COVID-19. These results would recommend adequate environmental reforms to policymakers to contain the spread and adverse effects of the virus. Therefore, there is a requirement to reconsider the system of transport and return to production by combining it with economic growth to protect the planet.

Bio-based earth composites present various environmental benefits, such as usable wastes, coproducts, abundant or renewable materials, etc. Moreover, the incorporation of bioaggregates in the earth matrix allows the buildings to act as an effective carbon sink. A growing number of studies are now focusing on the mechanical and hygrothermal properties of bio-based earth building materials. However, the durability of these types of material is a major concern, and knowledge of their various aspects is essential to anticipate maintenance and sustain the performance levels. Here, the durability of compressed earth composites, valorizing discarded earth containing 3% of barley straw, hemp shiv, or rice husk, is investigated. Due to the lack of internationally recognized standards to assess the durability of earthen materials and products, we proposed some testing procedures and discussed their relevance. The addition of these three bioaggregates decreases stiffness, as estimated by ultrasound velocity, and improves the resistance to impact and erosion by water. However, water absorption under low pressure is increased, and dry abrasion resistance is decreased. Moreover, the rice husk composite presents the best compromise.

Published: May 2021

Background

For the safety monitoring of vaccinations postlicensure, reports of adverse events after immunization (AEFIs) are crucial. New technologies such as digital mobile apps can be used as an active approach to capture these events. We therefore conducted a feasibility study among recipients of the influenza vaccination using an app for assessment of the reporting of AEFIs.

Objective

The goal of the research was to determine factors influencing adherence to and correct use of a newly developed app for individuals to report AEFI for 3 months using regular reminder functions, to identify determinants of AEFI occurrence and define reported AEFI types.

Methods

We developed the app (SafeVac) and offered it to recipients of the influenza vaccination in 3 occupational settings in fall 2018. In this prospective longitudinal feasibility study, data on AEFIs were generated through SafeVac for 3 months. Using logistic and Cox regression, we assessed associations between app adherence, correct app entry, AEFIs, and sociodemographic parameters.

Results

Of the individuals who logged into SafeVac, 61.4% (207/337) used the app throughout a 3-month period. App use adherence was negatively associated with female sex (odds ratio [OR] 0.47; CI 0.25-0.91) and correct app entry was negatively associated with older age (OR 0.96; CI 0.93-0.99) and lower education (OR 0.31; CI 0.13-0.76). AEFI occurrence was associated with female sex (hazard ratio 1.41; CI 1.01-1.96) and negatively with older age (hazard ratio 0.98; CI 0.97-0.99). The most common AEFIs reported were injection site pain (106/337), pain in extremity (103/337), and fatigue/asthenia (73/337).

Conclusions

Digital AEFI reporting was feasible with SafeVac and generated plausible results for this observation period and setting. Studies directly comparing SafeVac with conventional passive reporting schemes could determine whether such digital approaches improve completeness, timeliness, and sensitivity of vaccine vigilance. Further studies should evaluate if these results are transferable to other vaccinations and populations and if introduction of such a tool has an influence on vaccination readiness and therefore vaccine safety.
Medical Insights from Posts About Irritable Bowel Syndrome by Adolescent Patients and Their Parents: Topic Modeling and Social Network Analysis
Authors: Zhong Bu , Liu Qian
Published: May 2021

Background

Adolescents with irritable bowel syndrome (IBS) are increasingly seeking and sharing information about their symptoms in web-based health care forums. Their posts and those from their parents contain critical insights that can be used by patients, physicians, and caregivers to manage IBS symptoms.

Objective

The aim of this study is to examine the posts from adolescent patients and their parents in a health forum, IBS Group, to better understand the key challenges, concerns, and issues of interest to young patients with IBS and their caregivers.

Methods

Using topic modeling and social network analysis, in this study, we analyzed all the messages (over 750 topics and 3400 replies) posted on the IBS Group forum from 2010-2019 by adolescents with IBS aged 13-17 years and parents having children with IBS. We first detected 6 major topics in the posts by adolescent patients and parents on teenagers’ IBS symptoms and the interaction between the topics. Social network analysis was then performed to gain insights into the nature of web-based interaction patterns among patients and caregivers.

Results

Using the Latent Dirichlet Allocation algorithm and a latent Dirichlet allocation visualization tool, this study revealed 6 leading topics of concern in adolescents with IBS: school life, treatment or diet, symptoms, boys’ ties to doctors, social or friend issues, and girls’ ties to doctors. The top 6 topics in the parents’ discussions were school life, girls’ issues, boys’ issues, diet choice, symptoms, and stress. The analyses show that the adolescent patients themselves are most concerned about the effect of IBS on their everyday activities and social lives. For parents having daughters with IBS, their top concerns were related to the girls’ school performance and how much help they received at school. For their sons, the parents were more concerned about the pain and suffering that their sons had to endure. Both parents and adolescents gained social support from the web-based platform. Topic modeling shows that IBS affects teenagers the most in the areas of pain and school life. Furthermore, the issues raised by parents suggest that girls are bothered more by school performance over pain, whereas boys show exactly the opposite: pain is of greater concern than school performance.

Conclusions

This study represents the first attempt to leverage both machine learning approaches and social network analysis to identify top IBS concerns from the perspectives of adolescent patients and caregivers in the same health forum. Young patients with IBS must face the challenges of social influences and anxiety associated with this health disorder in addition to physical pain and other symptoms. Boys and girls are affected differently by pain and school performance and view the IBS impacts differently from the parents.
Characteristics of the Measurement Tools for Assessing Health Information–Seeking Behaviors in Nationally Representative Surveys: Systematic Review
Authors: Choi Hanna , Jeong Gyeonghui
Published: May 2021

Background

The coronavirus pandemic (COVID-19) has also emerged as an infodemic, thereby worsening the harm of the pandemic. This situation has highlighted the need for a deeply rooted understanding of the health information–seeking behaviors (HISBs) of people.

Objective

The aim of this paper was to review and provide insight regarding methodologies and the construct of content in HISB surveys by answering the following research question: what are the characteristics of the measurement tools for assessing HISBs in nationally representative surveys around the world?

Methods

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses was used as the framework for this study. A data search was performed through 5 international and 2 Korean databases covering the years between 2008 and 2020. Initially, studies performed among nationally representative samples were included to discover HISB survey instruments. The methodologies of the studies using HISB surveys were analyzed. For content analysis, 2 researchers reached a consensus through discussion by scrutinizing the contents of each survey questionnaire.

Results

A total of 13 survey tools from 8 countries were identified after a review of 2333 records from the search results. Five survey tools (Health Information National Trends Survey, Health Tracking Survey, Annenberg National Health Communication Survey, National Health Interview Survey, and Health Tracking Household Survey) from the United States, 2 instruments from Germany, and 1 tool from each of the countries of the European Union, France, Israel, Poland, South Korea, and Taiwan were identified. Telephone or web-based surveys were commonly used targeting the adult population (≥15 years of age). From the content analysis, the domains of the survey items were categorized as follows: information (information about health and patient medical records), channel (offline and online), and health (overall health, lifestyle, and cancer). All categories encompassed behavioral and attitude dimensions. A theoretical framework, that is, an information-channel-health structure for HISBs was proposed.

Conclusions

The results of our study can contribute to the development and implementation of the survey tools for HISB with integrated questionnaire items. This will help in understanding HISB trends in national health care.

Authors: Lánczky András , Győrffy Balázs
Published: May 2021

Background

Survival analysis is a cornerstone of medical research, enabling the assessment of clinical outcomes for disease progression and treatment efficiency. Despite its central importance, no commonly used spreadsheet software can handle survival analysis and there is no web server available for its computation.

Objective

Here, we introduce a web-based tool capable of performing univariate and multivariate Cox proportional hazards survival analysis using data generated by genomic, transcriptomic, proteomic, or metabolomic studies.

Methods

We implemented different methods to establish cut-off values for the trichotomization or dichotomization of continuous data. The false discovery rate is computed to correct for multiple hypothesis testing. A multivariate analysis option enables comparing omics data with clinical variables.

Results

We established a registration-free web-based survival analysis tool capable of performing univariate and multivariate survival analysis using any custom-generated data.

Conclusions

This tool fills a gap and will be an invaluable contribution to basic medical and clinical research.
