Análise fluidodinâmica computacional para otimização do desempenho de um veículo Baja SAE
Authors: Nascif Gabriel Nobre Alves , Escaleira Pedro Augusto Gama
Published: August 2021

Este trabalho trata-se de uma análise CFD (Fluidodinâmica Computacional) realizada no ANSYS, com o objetivo de quantificar as forças e coeficientes aerodinâmicos atuantes em um veículo off-road de competição estudantil Baja SAE, e, desta forma, possibilitar examinar a influência de diferentes formatos de carenagem na velocidade final do protótipo. O estudo aborda desde a parte inicial da modelagem da geometria em CAD (Desenho auxiliado por computador), a qual foi feita no software SOLIDWORKS, a simplificação do modelo para geração da malha, aplicação das devidas condições de contorno, e, finalmente, o pós-processamento da simulação fluidodinâmica, com análise dos gradientes de pressão e velocidades do fluxo de ar ao redor do veículo, a fim de justificar os valores de arrasto encontrados. Após a realização das análises computacionais, levou-se o veículo para teste em um dinamômetro de rolos para aferição de sua curva de potência por velocidade. Com isso, juntamente com os resultados adquiridos na simulação, foi possível a comparação dos dados das potências resistivas dos diferentes modelos avaliados no software com a potência disponível do próprio protótipo, chegando assim, em velocidades finais distintas para cada geometria. Além disso, averiguar a partir de qual velocidade o arrasto se torna relevante. No desenvolvimento, dois formatos de parede corta-fogo (estrutura que separa o piloto do tanque de combustível) foram analisados, o primeiro, com a geometria fechada, e o segundo, com uma redução da área em comparação ao modelo anterior. Com os resultados obtidos, fica evidente a considerável influência que esta estrutura exerce no veículo, com uma redução de 38% no coeficiente de arrasto e 163% de diferença na força aerodinâmica para uma velocidade de 15 m/s.
Un recorrido por las distribuciones de probabilidad
Authors: Nores María Laura
Published: August 2021

Las variables aleatorias tienen una distribución de probabilidad que bajo ciertas circunstancias viene dada en términos de una expresión conocida. Muchas veces esta fórmula se deduce fácilmente del contexto en el que surge la variable aleatoria, mientras que en otras ocasiones no resulta tan claro. En este artículo, se busca dar un paso más en la comprensión de las distribuciones de probabilidad más conocidas, intentando profundizar en la motivación que las origina y en la deducción de su expresión, destacando además relaciones existentes entre algunas distribuciones. De esta manera, el trabajo contribuye a brindar elementos para discernir cuándo resulta razonable asumir cierta distribución para una variable aleatoria en consideración.
La enseñanza de la geometría en la escuela secundaria: materiales didácticos para favorecer el estudio de figuras o cuerpos geométricos
Authors: Giarrizzo Alicia Mirta
Published: August 2021

Los estudiantes de secundario conocen los conceptos matemáticos de diferentes maneras durante sus trayectorias escolares. Y, si no tienen la posibilidad de enfrentarse a problemas desafiantes a fin de no solo decidir a cuáles de esos conceptos recurrir para resolverlos, sino también remediar los errores que aparecen en sus producciones, es muy probable que puedan tener dificultades para otorgarles sentido. Uno de los errores más frecuentes que se manifiestan en la resolución de problemas geométricos, se vincula con la aplicación de la proporcionalidad directa para calcular perímetros y áreas de figuras geométricas o áreas y volúmenes de cuerpos geométricos cuando varían una o más de sus dimensiones lineales. Considerando lo antes mencionado, con este trabajo se intenta compartir situaciones de enseñanza que fueron propuestas a estudiantes de un tercer año de secundario. Las mismas se basan en la construcción de figuras geométricas y de cuerpos geométricos de diferentes tamaños y formas para favorecer, a partir de su uso como material didáctico, el aprendizaje de contenidos relacionados con la proporcionalidad y la semejanza.

Authors: Ong Chin Fong , Lye Chun Teck
Published: August 2021

This study examines the online communities’ gratifications of social media usage and to understand how their perceived values within an online brand page environment can affect brand loyalty. In addition to the content-oriented and relationship-oriented aspects of uses and gratifications of online brand communities, this study also includes economic value to the existing model considering online promotions and rewards may encourage consumer brand engagement and subsequently lead to brand loyalty. The data collected via snowball sampling method consisted of the responses of 150 respondents who are in one or more online brand communities of different brands in Malaysia. The result shows that functional value and hedonic value are the most important motivators to drive brand loyalty in online brand communities. The result implies that the brand loyalty in online brand communities in Malaysia depends on the functionality and pleasant sensations experienced from the brand fan page. The result suggests that brand page should deliver informative, rich and customised information contents to fulfil the satisfaction of online communities. This study provides insight on social media users’ perceived values that drive their satisfaction and loyalty towards the brand via the fan page, which in turn helps brand marketing practitioners in Malaysia to understand on how these perceived values may influence the brand loyalty of online communities, particularly from the perspective of the Uses and Gratifications theory.

Covid 19 has brought many changes in human life. Currently, the campus is implementing an online learning system, aka online (in the network). This has an impact on final year students who are writing a thesis which will usually cause stress when compiling a thesis. Therefore, progressive muscle relaxation can reduce stress and learn how to relax tense muscles. The purpose of this study was to determine whether progressive muscle relaxation therapy can relieve or reduce stress levels in final year students. The research design used was quasi experimental. The research design used "pre test post test with control group design." The sample size obtained in this study was 30 respondents with a sampling technique carried out in the form of probability sampling with non-equivalent control group techniques. The data analysis used was the Wilcoxon test data analysis with a significance level of α = 0.05. If the value of ρ <0.05 then Ha is accepted. The research results from statistical analysis using the Wilcoxon test obtained the value of ρ = 0.001, where the value of ρ is smaller than the value of α = 0.05, so Ha is accepted. The results of the study proved that there was an effect of progressive muscle relaxation therapy on stress levels in final year students in the Indonesian Muslim University nursing study program. The conclusion of this study is that before being given progressive muscle relaxation therapy, the stress levels for final year students were moderate stress, severe stress and very heavy stress. Meanwhile, after being given progressive muscle relaxation therapy intervention, there was a decrease in stress levels, namely normal, mild stress and moderate stress.

Authors: Salam Syukriana
Published: August 2021

Insomnia is a common health problem in the elderly. The aging process causes a decrease or change in physical and psychological conditions, thereby increasing sleep latency, decreasing sleep efficiency, and waking up earlier. This study aims to determine the effect of murottal Al-Qur'an therapy on reducing insomnia levels in the elderly. Murottal Al-Qur'an therapy is one of the healing methods that can reduce stress hormones and increase endorphins, thereby increasing feelings of relaxation and happiness. This study used a one-group pretest-posttest design. Data analysis used paired T test. The population in this study were elderly people who experienced insomnia of ​​Puskesmas Usuku Wakatobi with a sample of 30 people (15 people in the control group and 15 people in the intervention group). The control group was not given therapy while the intervention group was given therapy. Insomnia level measurements before (pretest) and after therapy (posttest) were carried out in both groups. The results of the study using the paired t test showed that the provision of Al-Qur'an murottal therapy can reduce the level of insomnia in the elderly by a significant level of 5%. Murottal Al-Qur'an therapy can reduce the number of insomnia sufferers to 5 people (33%) mild insomnia and 10 people (67%) recovered from insomnia. Whereas in the control group, there was no significant reduction in insomnia levels. It can be concluded that, giving murottal Al-Qur'an therapy with Surah Al-Rahman can reduce insomnia levels in the elderly in the working area of ​​Puskesmas Usuku Wakatobi.
Question Dynamics
Authors: Barseghyan Hakob , Levesley Nichole
Published: August 2021

The paper presents a new scientonomic account of question dynamics. To explain the process of question acceptance and rejection, we begin by introducing the notion of epistemic presupposition and show how it’s different from the notion of logical presupposition. With the notion of epistemic presupposition at hand, we formulate the law of question acceptance, a new scientonomic axiom, which states that a question becomes accepted only if all of its epistemic presuppositions are accepted, and it is accepted that the question is answerable. We then show how the process of question rejection can be explained by means of the question rejection theorem, which states that a question becomes rejected when other elements that are incompatible with the question become accepted. To deduce this theorem in the usual scientonomic fashion (from the first law and the compatibility corollary), we first ascertain that the notion of compatibility/incompatibility is applicable to questions and show that one can legitimately speak of both question-theory and question-question incompatibility. We conclude by providing a quick illustration of the historical applicability of this new framework and suggest a number of questions for future research.

Authors: Kura Kabiru Maitama , Alkashami Mohamed
Published: August 2021

Employee voice which refers to the collective bargaining of employees in an organization, is gaining much attention and importance. Studies are linking the role and relationship between employee voice with many important individual and organizational outcomes. To understand its current state and influence, the present study tested employee voice and its influence on employee engagement and business performance. Following the relationship hypothesized model, the current study applied structural equation modeling using Smart PLS 3 and found a significant relationship between employee voice and business performance. In addition, the study also found significant influence of employee voice on employee engagement and business performance. The study also found that employee engagement was mediating the relationship between employee voice and business performance. The results confirm that employees who have the freedom and opportunity to share their ideas, opinions, and input in decision-making are likely to show high engagement, which contributes to increasing business performance. The study results offer important findings based on which implications are drawn for theory and practice for businesses aspiring to increase performance.

Objective: To determine the percentage of neonates who achieved therapeutic theophylline level (TTL) after receiving standard IV loading/maintenance aminophylline doses. To assess factors associated with achieving therapeutic theophylline concentrations and to describe adverse effects of aminophylline. Materials and Methods: This was a pilot, cross-sectional study. Preterm neonates ≤34 weeks’ gestation for which aminophylline was indicated for treatment of apnea were enrolled. Standard IV aminophylline dosage is 8 mg/ kg loading dose, followed by 1.5 mg/kg maintenance dose every 8 hours. Serum theophylline concentrations were measured prior to the 8th maintenance dose. Descriptive statistics, univariate and multivariate analyses were performed. Results: Twenty-five neonates (52% female) were enrolled: mean (standard deviation) gestational age and birth weight were 30.4 (2) weeks and 1,277 (415) grams, respectively. Aminophylline was initiated at a median (25%tile, 75%tile) postnatal age of 4 (1, 8) days. Baseline heart rate prior to the loading dose was 153 (13) beats-per-minute. Sixty percent of neonates achieved a therapeutic theophylline level. In the univariate analysis, being male and postnatal age ≤5 days were associated with successfully achieving a TTL. After adjusting for gender, postnatal age ≤5 days was the only factor associated with achieving a TTL (adjusted odds ratio 17.7, 95% confidence interval: 1.9, 164.4). Tachycardia and feeding intolerance were observed in 44% and 24% of neonates, respectively. Conclusion: Current IV aminophylline dosing conditions in Thailand achieved TTL in approximately two-thirds of neonates, suggesting therapeutic drug monitoring is beneficial for guiding dosing. A higher maintenance dose could be considered for neonates older than 5 days.

Objective: Depressive symptoms are common mental health problems among the family caregivers of patients with dementia. However, little is known about the prevalence of depressive symptoms among the family caregivers of patients with dementia in Indonesia. This study aimed to examine: 1) the factors predicting depressive symptoms, 2) the mediating role of social support in the relationship between burden and depressive symptoms, and 3) the association between depressive symptoms and healthcare utilization among family caregivers. Methods: This was a cross-sectional study involving 250 family caregivers of patients with dementia recruited from four hospitals in Java, Indonesia. Data were collected by Zarit Burden Interview (ZBI); the Neuropsychiatric Inventory Questionnaire (NPI-Q), the Mastery scale, the Multidimensional Scale of Perceived Social Support, and the Center for Epidemiologic Studies Depression (CES-D) Scale. Descriptive statistics, chi-square test, hierarchical multiple linear regression, and Baron and Kenny’s regression method were used to analyze the data. Results: The results revealed that about a quarter of the participants (24.8%) experienced depressive symptoms. Caregiver burden, mastery, behavioral and psychological symptoms of dementia, and social support explained 45.5% of the variance in the prevalence of depressive symptoms among family caregivers (R2=0.455). Social support also partially mediated the association between caregiver burden and depressive symptoms. There was no association between depressive symptoms and the use of healthcare services among the family caregivers. Conclusion: The findings revealed that social support is a mediating factor affecting the relationship between caregiver burden and depressive symptoms. Interventions targeting social support to help alleviate caregiver burden would be effective in helping reduce depressive symptoms in the family caregivers of patients with dementia.

The Struggle for Class Ranks and Prosecutor’s Dress during Ukrainian Independence: Historical, Legal, and Cultural Perspectives
Authors: Kaluzhna Oksana
Published: August 2021

This article is devoted to the problem of confrontation between researchers about the dress of Ukrainian prosecutors and whether prosecutors should have class ranks (special ranks, equated to military ranks and providing bonuses to salaries). This confrontation has lasted for more than 10 years. Ukrainian MPs have proposed
legislative amendments to solve this problem, but the approaches of the proposals are in opposition to each other.
According to the Law of Ukraine ‘On the Prosecutor’s Office’ of 19 September 2019, the Ukrainian Parliament, at the ninth convocation, completely abolished the class ranks and military-like dress of prosecutors. At the same time, a Draft Law on their restoration is being considered by the current session of the same parliament, and the initiators call their abolishment a ‘premature mistake’. Regardless of the consequences of the consideration of this Draft Law, this issue may not be resolved in the near future in Ukraine, as it is an integral part of the worldview and culture of the pro-Western or Eurasian vector of the prosecutor’s office.
The aim of the present piece of legal scholarship is to provide a report that is as informative as possible on the consistency between class ranks, prosecutor’s dress, and the principles of justice, the functions of the prosecutor, and his/her role in the justice system in comparison with the approaches of other states. Moreover, it is important to advise the legislative initiatives, and the voice of parliamentarians since this issue has gained traction in the professional environment and in society.
The author analysed the issue of prosecutor’s dress and class ranks in relation to various aspects – constitutional functions and roles of prosecutors, procedural law, comparative law, international law, incentive, as well as psychological, value-philosophical, cultural, and deontological aspects, etc.
The prosecutor’s dress code of the Council of Europe’s 47 member states has been clarified; it was found that only prosecutors from Russia, Azerbaijan, and Armenia have the military dress; in other countries, prosecutors wore a robe or business suit. Periods of transformation of the prosecutor’s office had taken place in all the post-Soviet republics as a part of their European integration processes – Lithuania, Latvia, and Estonia, as well as Georgia and Moldova, abandoned the military dress of prosecutors as associate members of the EU.
The remuneration system of prosecutors in Poland and Germany is analysed in detail, where seniority, experience, qualifications, and position are taken into account in the ‘rates’ (Poland) or ‘R levels’ (Germany) of the basic salary of prosecutors. ‘Rates’ and ‘R levels’ are important only for calculating wages and are not analogous to class ranks.

Published: August 2021

Periglacial melting processes can provide the water source for secondary lahars triggered by volcanic and/or meteorological phenomena on volcanoes. Between December 2015 and April 2016, four major lahars were reported southeast of Chimborazo volcano (Ecuador). Fieldwork allowed determining the area (1.670.37 km2), volume (3E+05 to 7E+05 m3), peak discharge (100 - 150 m3/s) and mean speed (2 - 4 m/s) of these flows, which affected the local infrastructure and threatened several towns downstream (>1000 inhabitants). This case study suggests that anomalous periglacial melting could have been induced by: i) an increase in temperatures at periglacial altitudes partly ascribed to El Niño phenomenon, ii) albedo reduction of the glacier due to ash fallout from Tungurahua volcano (40 km east of Chimborazo) which erupted from 1999 to 2016 and, iii) a slight increase in internal activity at Chimborazo prior and during the lahars occurrence, as evidenced by more seismic events and thermal anomalies. These simultaneous factors could have led to the formation, outburst and/or overflow of superficial and intra-glacier ponds providing the water source to generate lahars on a dormant volcano.

Along with the development of increasingly sophisticated technology, vessels as means of transportation at sea have progressed a lot. There is a part of activities aboard vessel which determines the effectiveness of every voyage of the vessel which is communication aboard vessel. Communication which occurs intensively and properly leads to effective communication. In radio communication committing flouting maxim of conversation could not be avoided. The radio communication context plays significant role to interpret the meaning of the speech itself. This study aims to determine the conversational implicature used aboard vessel and the flouting maxims which arise especially from the external radio communication. The design of the research was descriptive qualitative in which the data were taken from the radio communication among cadet’s radio communication practice in bridge simulator. The finding shows that the four types of maxim flouting were committed by the duty officers on radio communication. The highest maxim flouted was flouting maxim of quantity as much as 36,3%. The less frequent maxim to be flouted was maxim of manner and quality as much as 18,2%. The other 27,3% was the occurrence of flouting maxim of relevance. The rationales behind the flouting maxims were also revealed in this study to get the knowledge and best practices onboard radio communication.

Validating a biophysical parasite model with fish farm pen and plankton trawl data
Authors: Adams TP , Marshall S , Brown S , Black K
Published: August 2021

Biophysical models of parasite dispersal are being increasingly used as a method for screening marine aquaculture developments, whether in establishment of new sites or expansion of existing sites, or planning of farmed fish health management strategies on local or regional spatial scales. How well these models reflect reality, however, is often brought into question, due to the difficulties in validating their outputs. Larval parasitic sea lice can spend up to around 14 d in the water column, as a result potentially travelling several 10s of km between farms. Lice distribution in the water column is typically patchy and low density. Furthermore, infection can occur from lice carried by wild fish. Combined with rapid population turnover and larval exchange between farms, this causes difficulties in attributing links between juvenile lice and their sources. We sought to validate a biophysical model of sea lice dispersal using plankton trawl abundance data and farm site juvenile lice counts. Unusually high farm lice abundances over the study period allowed model predictions of larval density to be compared with trawled samples, in addition to mapping the link between parent and offspring lice counts found on farm sites. We compared the prediction of the larval dispersal model with a site neighbourhood-based metric of infection pressure. Our results validate the ability of the model to predict variation in larval density over time and space and suggest an exponential relationship between estimated infection pressure and observed site juvenile count.

This investigation studied the effect of concentrated growth factor and nanofat on aging skin of nude mice induced by
D-galactose. BALB/c mice were randomly divided into five groups: 5 mice in the control group were fed normally without any intervention, 9 mice were treated with concentrated growth factor (CGF), 9 mice were treated with nanofat (NF), 9 mice were treated with CGF+NF, and 9 mice in the model group (no treatment after subcutaneous injection of D-galactose). Relevant indicators are measured and recorded. In skin and serum, SOD and GSH content in the model group were significantly lower than those in other groups (P<0.05), and the MDA of the three treatment groups was significantly lower than that of the model group (P<0.05). Compared with the control group, the contents of total collagen, type I collagen and type III collagen in the NF group and model group were decreased in different degrees (P<0.05); the contents of elastin and elastic fiber in the skin of nude mice in the model group and NF group were significantly decreased. Compared with the model group, he number of CD31 and VEGF in the treatment group was significantly increased (P<0.01); the skin AGE content of three treatment groups was significantly lower (P<0.05). These findings suggest that concentrated growth factor and nanofat may have a significant effect on delaying aging skin induced by D-galactose in nude mice.

Authors: Medina-Pérez Jessica , González-Campos José
Published: August 2021

En la actualidad los perfiles de egreso son considerados de gran importancia, ya que delinean la formación que se entregará en cada carrera, sin embargo, encontramos una variedad de elementos en ellos, algunos muy completos y otros con escasas competencias mencionadas especialmente, en las carreras de pedagogía, como se señala en este estudio. La siguiente investigación propone los elementos que deberían considerarse para la construcción de perfiles de egreso de los futuros profesores, basados en una revisión bibliográfica y las principales Políticas Educativas de Chile. Los perfiles de egreso son fundamentales para la construcción de mallas y programas de estudios, asimismo su correcta elaboración es crucial para la consideración del modelo de profesor que queremos para el país, los que deben alinearse con las demandas de la sociedad, las Políticas Educativas actuales y las experiencias internacionales exitosas. Este trabajo propone un perfil de egreso para profesores, orientado y focalizando competencias para la Formación Inicial Docente, delineando así un modelo de profesor, quedando constituido por: una competencia global común, competencias genéricas o transversales separadas por ejes, competencias de la disciplina y competencias del sello de la universidad.
En este trabajo se propone un perfil de egreso para profesores y busca contribuir a orientar, focalizar y potenciar las Políticas Educativas de Formación Inicial Docente, tanto a nivel regional como nacional logrando un perfil de egreso para profesores y delineando un modelo de profesor para el país.

Se presenta una estrategia didáctica, con enfoque de resolución de problemas, mediante la modelación matemática para realizar un modelo de utilidad para prevenir el contagio del COVID-19, usando conceptos matemáticos; desarrollada en la asignatura de Matemática III, durante el semestre 2020-I en la Carrera Profesional de Arquitectura de la Universidad Nacional Hermilio Valdizán de Huánuco-Perú. La investigación fue de enfoque cuantitativo, nivel descriptivo y diseño no experimental. La estrategia constó de 5 fases: fase 1: formulación del problema del contexto para prevenir el contagio de COVID-19, con un modelo de utilidad usando superficies cuadráticas o curvas; fase 2: marco teórico y objetivos; fase 3: modelación matemática; fase 4: elaboración de planos del modelo de utilidad; fase 5: modelo de utilidad en 3D. La evaluación de la estrategia se realizó a través de rúbricas de: evaluación docente, autoevaluación, coevaluación entre estudiantes y la heteroevaluación de expertos. Se concluye que, con la aplicación de la estrategia, la mayoría de los estudiantes lograron un nivel de desempeño mayor al esperado (resolutivo) en la obtención del modelo de utilidad, permitiendo a los estudiantes relacionar las matemáticas con problemas de la vida real, con pensamiento complejo, creatividad y aplicando conocimiento de la carrera de Arquitectura.
Maximiliaan August Schwartz, 1884-1973

Published: August 2021

Classicus Max Schwartz was een veelzijdig geleerde, een gedreven docent en beminnelijke rector. Pas op latere leeftijd, vanaf 1951, publiceerde hij vertalingen van de belangrijkste Griekse en Romeinse verhalende schrijvers, zoals de Ilias en Odyssee van Homerus en de Aeneis van Vergilius die nog steeds herdrukt worden. Uit zijn aanpak en stijl blijkt dat hij de moderne tijd van de wederopbouw perfect aanvoelde: hij zocht en vond een nieuw publiek, dat wel geïnteresseerd was in de klassieke oudheid maar er niet of amper mee was opgegroeid.
A nyálkahártya-védelem mechanizmusa és a vírusinvázió csökkentésének lehetőségei Covid-pandémia idején
Authors: Hodinka László
Published: August 2021

A koronavírus behatolási kapuja a légzőszervek nyálkahártyája. A Covid-19 súlyosságát, szervi manifesztációit és kimenetelét a megtámadott szervezetbe jutó vírustömeg, a vírusterhelés határozza meg. A vírus áthatolásában, az epithelsejtekkel való fúziójában és replikációjában a légutak és a gastrointestinalis nyálkahártya állapota és védekező rendszerének kapacitása a döntő. Ennek függvénye a közvetlen neuralis terjedés, a mélyebb légutakba hatolás és a lymphogen szóródás is. A vírus megkötődése és bekebelezése aktív folyamat, enzimatikus transzfer útján jut az epithelsejt endomszómáiba, ahol a természetes védekezés elemei érzékelik és ezzel kiváltja az első elhárító reakciókat. Ezek a teljes im­munrendszert alarmírozzák, és a vírusterheléssel arányos gyulladásos és enzimatikus védekező folyamatok egész láncolatát indítják meg (citokin- és bradikininvihar). A Covid-patológia súlyossági végpontja az alveolitis, cerebralis vasculitis és a belszervi károsodás, amelyek sokszor fatálisak. A légúti mucosa felszíni faktorok kiválasztásával és az adaptív immunrendszer sejt­jeinek toborzásával és aktiválásával védekezik. Ez utóbbinak fontos eleme a szekretoros IgA korai megjelenése a mucosában. A vírusinvázió megelőzésének lehetősége a carragenintartalmú orrspray alkalmazása, amely a carragenin gélképző sajátsága útján bevonja a vírust, és megakadályozza annak kötődését. Ez a hatás a korábbi ví­rus­­jár­vá­nyokban már működött, és az első Covid-19-tapasztalatok is megerősítik protektív sze­­repét.
