Authors: Kebede Tinsae , Kumar Dharmendra , Sharma Pramod Kumar
Published: July 2020

A virus known as novel corona (SARS-CoV-2) which causes COVID-19 pandemic disease is
an invisible enemy, appeared for the first time in the world’s most populous country, China, and became
a reason for causing death of many people all over the world. As a result of this, a remarkable investigation
and clinical trials are ongoing to discover the treatment for this devastating pandemic disease. Effective
vaccines and anti-viral treatments are immediately required in order to control and eradicate the
disease. But still, neither vaccine nor any drug is approved for prevention and control of COVID-19
pandemic. Proper and well-designed strategies are needed to reduce social and economic consequences
arisen due to this pandemic disease. There are some drugs that are used for other diseases which are
showing valuable outcomes to elicit the virus causing COVID-19. However, there are no approved drugs
full of clinical evidence. A systematic review literature search was carried out from different electronic
databases to identify available articles on the effectiveness of drugs against COVID-19.Four therapies
suggested recently via World Health Organization (abbreviated “WHO”) that were later incorporated for
under taking efficient clinical trial of the newly established project (European Discovery), comprise
remdesivir, combination of anti-viral drugs (lopinavir and ritonavir), lopinavir plus ritonavir with beta
interferon, and anti-malarial drugs like hydroxyl chloroquine and chloroquine. On May 25 2020, hydroxychloroquine
and chloroquine were suspended by WHO from Solidarity trial because of their safety
and efficacy concerns. However, there were neither effective specific antivirals nor drug combinations
approved which were supported by great-level of clinical evidence.

O objetivo desse estudo foi revisar sistematicamente as publicações sobre engajamento escolar nas bases SciELO, PsycINFO e ERIC com os seguintes descritores: “school engagement”, “engajamento escolar” e “envolvimento escolar”. Foram selecionados os estudos que atendiam aos critérios de inclusão: (a) artigos cujos descritores supracitados constavam no título, resumo ou nas palavras-chave; (b) estudos publicados na modalidade artigo científico e (c) no período de 2014 a 2018. Como critérios de exclusão: (a) artigos com foco em outros temas, (b) não disponíveis na íntegra e (c) duplicados. Foram encontrados 410 estudos e 203 selecionados. A maioria dos estudos é correlacional e a produção sobre engajamento se concentra no eixo América do Norte/Europa. O engajamento foi tratado na maioria dos estudos como um constructo tridimensional e foram encontradas 35 escalas que avaliam o engajamento. Faz-se necessário mais estudos experimentais e quasi-experimentais devido à importância destes para a avaliação e desenvolvimento de intervenções que visem melhorar o engajamento escolar e também estudos que avaliem a relação entre o engajamento escolar e outras variáveis pertinentes ao contexto escolar.
PISA, TIMSS e PIRLS em Portugal: Uma análise comparativa
Authors: Rosa Vítor Alberto , Maia João Sampaio , Mascarenhas Daniela , Teodoro António
Published: July 2020

Neste artigo apresentamos uma análise comparativa entre três inquéritos internacionais: PISA, levado a cabo pela OCDE, o TIMSS e o PIRLS, realizados pela IEA, tendo em conta os seus objetivos gerais e uma correlação dos dados referentes a Portugal (por regiões da NUTS III). A revisão bibliográfica e documental mostrou como os resultados podem ser reformulados ou reinterpretados pelos diferentes atores sociais e que são vistos pelos decisores políticos e pelas organizações como uma ferramenta de comparação dos sistemas escolares, reveladora de pontos fortes e pontos fracos. A análise dos resultados gerais evidencia que Portugal tem vindo a melhorar os seus resultados no PISA, nos três domínios (leitura, matemática e ciências), que melhorou no TIMSS em matemática e piorou em leitura no PIRLS. A análise comparativa por regiões revelou que existe uma diferenciação dos resultados por regiões e que, enquanto o fator domínio não se apresenta como relevante, o fator objeto de avaliação em cada estudo parece determinante para os resultados dos questionários. Revelou, ainda, que há uma relação direta entre o PIB/habitante e os resultados dos questionários nas regiões com valores extremos de PIB/habitante, mas que essa relação não existe para a generalidade das regiões.
Autoeficácia, estratégias de coping e os efeitos das relações interpessoais e organizacionais de discentes de Ciências Contábeis
Authors: Meurer Alison Martins , Lopes Iago França , Colauto Romualdo Douglas
Published: July 2020

Esta pesquisa busca verificar a influência da autoeficácia nas estratégias de coping mediada pelas relações interpessoais e organizacionais estabelecidas por discentes de Ciências Contábeis. Para tal, a pesquisa descritiva com abordagem quantitativa tem como amostra 311 discentes de Instituições de Ensino Superior Público e Privado, localizadas no estado do Paraná (Brasil), e matriculados no ano de 2018. A partir da técnica de Modelagem de Equações Estruturais (MEE) foi possível constatar que as relações interpessoais e organizacionais atuam como mediadoras da autoeficácia académica com estratégias de coping voltadas para a recusa e distração. Estes resultados ilustram que reconhecer a posição mediadora do relacionamento interpessoal e organizacional entre a autoeficácia e as estratégias de coping é oportuno, na medida em que são constructos ligados ao processo de superação das adversidades vivenciadas no ensino superior. Os resultados indicam que, ao fomentar relações interpessoais e organizacionais satisfatórias, é maximizada a capacidade do discente de enfrentar os problemas de forma mais direta. Essa habilidade torna-se importante, pois contribui para o amadurecimento do discente e para o desenvolvimento de capacidades de enfrentamento adequadas para as situações vivenciadas no ambiente socioacadémico.

Federalismo fiscal y las asignaciones de transferencias en San Luis Potosí, México
Authors: González Ramírez Pedro Isidoro , Gomez Galarza Edgar
Published: July 2020

El objetivo es estudiar la asignación de transferencias que realiza el Gobierno Federal, bajo el marco del federalismo fiscal, a los 58 municipios del estado de San Luis Potosí durante el periodo 2000-2018. Con un panel de datos de 1102 observaciones se estimó un modelo de regresión múltiple para datos agrupados y un modelo de efectos fijos. Las transferencias estudiadas fueron las del Ramo 33, del Fondo General de Participaciones y del Fondo de Fomento Municipal. Los resultados muestran que en las del Ramo 33 y del Fondo de Fomento Municipal no se observa influencia de filiación política como determinante para la asignación de recursos. Mientras que en las del Fondo General de Participaciones existe evidencia estadísticamente significativa de mayores asignaciones de recursos para aquellos municipios con filiación política tanto federal como conjunta. El estudio puede replicarse en otros municipios para obtener mayor evidencia. La propuesta es original para el estudio de transferencias hacia los municipios de San Luis Potosí. Se concluye que la filiación política es un factor que determina una mayor asignación de transferencias hacia municipios en el periodo estudiado.
Modelo ARIMA aplicado al tipo de cambio peso-dólar en el periodo 2016-2017 mediante ventanas temporales deslizantes
Authors: Ayala Castrejon Rey Francisco , Bucio Pacheco Christian
Published: July 2020

En este trabajo se genera un abanico de pronósticos del tipo de cambio peso-dólar a través de un modelo ARIMA(1,1,1) en el periodo 2016-2017, dicho modelo que se aplica al tipo de cambio peso-dólar se estima de diversas maneras mediante el uso de ventanas temporales deslizantes; asimismo, se identifica la existencia de problemas de cambio estructural y se propone un ajuste óptimo al modelo ARIMA(1,1,1) propuesto, lo cual permite mejorar el pronóstico. La evidencia empírica resalta lo complejo que es realizar un pronóstico con datos que tienen un comportamiento cambiante a través del tiempo y que presentan además problemas de cambio estructural; en este sentido es recomendable utilizar mecanismos que ayuden a perfeccionar el pronóstico como en este caso lo fue el uso de ventanas temporales deslizantes y la propuesta de cambio estructural. Se concluye que el pronóstico a 30 días, tanto de ventanas deslizantes como de ventanas deslizantes crecientes por la derecha, es viable, ya que con un intervalo de confianza del 95% se tienen 12 registros de 30 dentro del rango del valor real del tipo de cambio peso-dólar.
Tasa de política monetaria en México ante los efectos de Covid-19
Authors: Sánchez Vargas Armando , López-Herrera Francisco
Published: July 2020

La crisis económica alimentada por el Covid-19 ha producido choques de oferta y demanda que afectan al producto potencial y a las preferencias de los consumidores, impacto que sugiere que la tasa real neutral de interés se modificó y, por ende, la tasa real de interés debe ajustarse para no generar una contracción económica más profunda en México. Estimamos el valor de la tasa neutral utilizando el método de Laubach y Williams, basado en el filtro de Kalman, y confirmamos los resultados con un modelo cointegrado de vectores autorregresivos (CVAR). Los resultados muestran que la tasa real neutral, teóricamente congruente con el pleno empleo y la meta de inflación, se reduce hasta 0.1% y la nominal hasta 3.1%, lo que sugiere la existencia de suficiente espacio para una política monetaria expansiva que permita enfrentar la crisis e impulsar la actividad económica durante al menos tres años.

Published: July 2020

Propolis is a mixture of resin and saliva of Tetragonula spp. that have antifungal activity. The purpose of this study was to develop spray-dried microcapsule propolis (SDMP) and to analyze its antifungal activity to Candida albicans. The SDMP was obtained using a spray drying method by maltodextrin and gum arabic coating. The antifungal activity of SDMP of rough propolis (taken from the outside beehive) and smooth propolis (taken from the inside beehive) was analyzed. The macroscopic characterization showed that SDMP has a powder form with brownish-yellow color. The microscopic characterization showed SDMP has a spherical uniform particle shape with particle size 9.32 - 14.61 µm. The encapsulation efficiency of smooth and rough SDMP was 81.22% and 83.04%; moisture content 5.58% and 5.84%; water solubility 98.19% and 98.31%, respectively. The microbial inhibitory concentration to C. albicans was the diameter of 6.33±1.5 to 10±2.5 mm. SDMP displayed remarkable activity in the assays against C. albicans.

Published: July 2020

A three-dimensional pore structure on activated carbon derived from hierarchically bamboo stem was synthesized in the monolithic form for increased applicability as a supercapacitor electrode. The preparation involved two step carbonizations, using a chemical activation at different concentrations. Subsequently, the morphology, chemical content, specific surface area and pore size distribution, as well as crystalline degree were evaluated with scanning electron microscopy, energy X-ray (EDX), N2 sorption and X-ray diffraction, respectively. Therefore, cyclic voltammetry (CV) was used to assess the electrochemical performance, in a two electrode system. The result shows the significant impact of the three-dimensional structure on electrochemical performance, and the optimized sample exhibited specific capacitance of 168.8 F g-1, energy density of 23.44 Wh kg-1, and power density of 84.46 W kg-1.
Mapping of Health Literacy and Social Panic Via Web Search Data During the COVID-19 Public Health Emergency: Infodemiological Study (Preprint)
Authors: Xu Chenjie , Zhang Xinyu , Wang Yaogang
Published: July 2020

BACKGROUND

Coronavirus disease (COVID-19) is a type of pneumonia caused by a novel coronavirus that was discovered in 2019. As of May 6, 2020, 84,407 cases and 4643 deaths have been confirmed in China. The Chinese population has expressed great concern since the COVID-19 outbreak. Meanwhile, an average of 1 billion people per day are using the Baidu search engine to find COVID-19–related health information.

OBJECTIVE

The aim of this paper is to analyze web search data volumes related to COVID-19 in China.

METHODS

We conducted an infodemiological study to analyze web search data volumes related to COVID-19. Using Baidu Index data, we assessed the search frequencies of specific search terms in Baidu to describe the impact of COVID-19 on public health, psychology, behaviors, lifestyles, and social policies (from February 11, 2020, to March 17, 2020).

RESULTS

The search frequency related to COVID-19 has increased significantly since February 11th. Our heat maps demonstrate that citizens in Wuhan, Hubei Province, express more concern about COVID-19 than citizens from other cities since the outbreak first occurred in Wuhan. Wuhan citizens frequently searched for content related to “medical help,” “protective materials,” and “pandemic progress.” Web searches for “return to work” and “go back to school” have increased eight-fold compared to the previous month. Searches for content related to “closed community and remote office” have continued to rise, and searches for “remote office demand” have risen by 663% from the previous quarter. Employees who have returned to work have mainly engaged in the following web searches: “return to work and prevention measures,” “return to work guarantee policy,” and “time to return to work.” Provinces with large, educated populations (eg, Henan, Hebei, and Shandong) have been focusing on “online education” whereas medium-sized cities have been paying more attention to “online medical care.”

CONCLUSIONS

Our findings suggest that web search data may reflect changes in health literacy, social panic, and prevention and control policies in response to COVID-19.
Personalized stratification of back to work risk amidst COVID-19: A machine learning approach (Preprint)
Authors: Lam Carson , Calvert Jacob , Barnes Gina , Pellegrini Emily , Lynn-Palevsky Anna , Green-Saxena Abigail , Hoffman Jana , Das Ritankar
Published: July 2020

BACKGROUND

In the wake of COVID-19, the United States has developed a three stage plan to outline the parameters to determine when states may reopen businesses and ease travel restrictions. The guidelines also identify subpopulations of Americans that should continue to stay at home due to being at high risk for severe disease should they contract COVID-19. These guidelines were based on population level demographics, rather than individual-level risk factors. As such, they may misidentify individuals at high risk for severe illness and who should therefore not return to work until vaccination or widespread serological testing is available.

OBJECTIVE

This study evaluated a machine learning algorithm for the prediction of serious illness due to COVID-19 using inpatient data collected from electronic health records.

METHODS

The algorithm was trained to identify patients for whom a diagnosis of COVID-19 was likely to result in hospitalization, and compared against four U.S policy-based criteria: age over 65, having a serious underlying health condition, age over 65 or having a serious underlying health condition, and age over 65 and having a serious underlying health condition.

RESULTS

This algorithm identified 80% of patients at risk for hospitalization due to COVID-19, versus at most 62% that are identified by government guidelines. The algorithm also achieved a high specificity of 95%, outperforming government guidelines.

CONCLUSIONS

This algorithm may help to enable a broad reopening of the American economy while ensuring that patients at high risk for serious disease remain home until vaccination and testing become available.
Explore the Possible Impact of BCG Vaccination Policy on the Morbidity, Mortality, and Recovery Rates due to COVID-19 Infection. (Preprint)
Authors: Chang Yue-Cune
Published: July 2020

BACKGROUND

The Coronavirus Disease-19 (COVID-19) is the new form of an acute infectious respiratory disease and has quickly spread over most continents in the world. Recently, it has been shown that Bacille Calmette-Guerin (BCG) might protect against COVID-19. This study aims to investigate the possible correlation between BCG vaccination and morbidity/mortality/recovery rate associated with COVID-19 infection.

OBJECTIVE

Our findings confirm that the BCG vaccination might protect against COVID-19 virus infection.

METHODS

Data of COVID-19 confirmed cases, deaths, recoveries, and population were obtained from https://www.worldometers.info/coronavirus/ (Accessed on 12 June, 2020). To have meaningful comparisons among countries’ mortality and recovery rates, we only choose those countries with COVID-19 infected cases at least 200. The Poisson regression and logistic regression were used to explore the relationship between BCG vaccination and morbidity, mortality and recovery rates.

RESULTS

Among those 158 countries with at least 200 COVID-19 infected cases, there were 141 countries with BCG vaccination information available. The adjusted rates ratio of COVID-19 confirmed cases for Current BCG vaccination vs. non-Current BCG vaccination was 0.339 (with 95% CI= (0.338,0.340)). Moreover, the adjusted odds ratio (OR) of death and recovery after coronavirus infected for Current BCG vaccination vs. non-Current BCG vaccination were 0.258 (with 95% CI= (0.254,0.261)) and 2.151 (with 95% CI= (2.140,2.163)), respectively.

CONCLUSIONS

That data in this study show the BCG might provide the protection against COVID-19, with consequent less COVID-19 infection and deaths and more rapid recovery. BCG vaccine might bridge the gap before the disease-specific vaccine is developed, but this hypothesis needs to be further tested in rigorous randomized clinical trials.

Published: July 2020

Background: Orchidopexy is a procedure of securing the testis inside the scrotum in patients with cryptorchidism. In the literature, various dissection techniques have been described to lengthen the spermatic cord to ensure a tension-free fixation of the testis to the lowest point of the scrotum.Objectives: The aim of this study is to determine if incorrect measurement of the spermatic cord’s length during open inguinal orchidopexy had led surgeons to over dissect the cord in a way that may pose an increased risk of testes, vas deferens and spermatic vessels.Materials and Methods: We prospectively studied the results of 40 orchidopexies performed in 40 patients with peeping or canalicular undescended testis , which was done at the Jordan university hospital in Amman from April 2018 to March 2019 , We compared the position of the testis before and after tunneling inside the inguinal canal. The difference in length is measured and analyzed.Conclusion: Failure to account for the subcutaneous fat layer thickness during orchidopexy increases the likelihood of over dissecting the spermatic cord which increases the risk of vas and vessels injury In this study we found that there is a difference between the cord length outside and inside the canal with excess length after passing the cord inside the canal ranges from 1-3 cm . This means that we do not need to dissect the cord to make the testis reaches the scrotum from outside. This decreases the risk of harming the cord and its contents.

Published: July 2020

Objective: In this study, we evaluated the effects of human embryonic derived neural progenitor cells on neurological score, histopathological changes, and miRNA-210 as biomarkers of regeneration.

Methods: The animals were randomly divided into the four groups: Sh (sham), MCAO (middle cerebral artery occlusion), MCAO+PBS, MCAO+Cell. One day after MCAO induction, embryonic derived neural progenitor cells (hESC-NPCsGFP) or PBS were injected intracerebroventriculary in MCAO+Cell or MCAO+PBS groups. On day 1, 2, 3, and 7 after ischemia induction, the neurological score was tested in each rat. At 48h, the expression of miRNA-210 was evaluated and 7 days after, the pathological assessments were performed by H&E staining.

Results: Neurological score showed the promotion of functional recovery in MCAO+Cell group. Based on H&E staining, the percentage of neural death in ischemic region reduced in MCAO+Cell group. The miRNA-210 significantly upregulated in both brain and blood samples.

Conclusion: According to the findings, hESC-NPCsGFP injection could up-regulate the miRNA-210 of tissue and blood to support the neuroprotective and regenerative effect of hESC-NPCsGFP in the ischemic lesion and improved the neurological score and reduce the neural death in ischemic region.

Published: July 2020

Based on the proximity of their habitat to the settlement, rats were classified as domestic, peridomestic, and sylvatic. Domestic rats are the most potent to transmit zoonotic diseases. Several studies report overlapping habitat on certain species as of transmission possibility between species in turn increase the number of reservoir species. This article purposes to criticize species domestication potency related to foraging and nesting behavior. The primary data were obtained from the rat survey result that was conducted in Banjarnegara district in 2017. The data were descriptively analyzed with the examination of the possibility of domestication phenomena on R. exulans, R. tiomanicus, and R. norvegicus species. The conclusion from this study is the rat domestication potency was relatively low on R. exulans and R. tiomanicus. Both species were good adapting with food resourced from human's food, however nesting behavior has become barriers to domestication. Rattus norvegicus has been long adapted to food resource and human environment by nesting in settlement so that this species classified as a domestic rat.

Results showed that n-hexane extract had moderate cytotoxic effect on T47D cells with IC50 value of 582.13 ± 61.64 µg/mL, while the ethanol and ethyl acetate extract did not have cytotoxic effect on T47D cells. TLC results indicated that n-hexane extract of noni fruit contains anthraquinone and coumarin.
Self-construal priming reconsidered: Comparing effects of two commonly used primes in the UK and China
Authors: Yang Shengyu , Vignoles Vivian L
Published: July 2020

Self-construal priming was devised to mimic the effects of chronic cross-cultural differences. Primes designed to activate independent/interdependent self-construals have been found to affect numerous culturally relevant outcomes. However, researchers have rarely checked precisely what these primes activated, nor tested their cross-cultural equivalence. We compared two common priming tasks, Similarities vs. Differences with Family and Friends (SDFF) and Sumerian Warrior Story (SWS), across seven dimensions of independence/interdependence among 118 British and 178 Chinese participants. The two tasks activated different combinations of self-construal dimensions. SWS showed a similar pattern of effects across cultures, whereas SDFF more strongly affected Chinese participants. Neither manipulation closely mimicked the pattern of pre-existing cross-cultural differences between samples. We propose researchers should develop more precisely targeted self-construal primes.

Authors: Fung Roderick , Fong Ben Y.F
Published: July 2020

Service-learning is a useful learning activity for students to understand and analyse the health and social conditions of elderly recipients. It offers a practical environment for the study of ageing. Students make the service-learning meaningful, by combining the course idea and concepts in the activity during service. Students enhance learning experience by finding an appropriate health suggestion to the elderly while investigating the health conditions of the elderly. Students enrich additional vision by designing effective activities for the elderly and explaining the course idea to the elderly. The elderly provide opinion in the activity and inspire students to have a better management for further life and service-learning. In this study, an experience of service learning in elderly home is described. It covers several themes: (a) preparation of service learning, (b) analysis of designed activities, (c) reflection on this service-learning, (d) comparison of in-class learning and service-learning.
Improvement of Safety in Operating Theatres by Training and Teamwork
Authors: Lam Carina Y.H , Ng Tommy K.C , Yee Hilary H.L
Published: July 2020

Medical incidents in public hospitals in Hong Kong have persisted for years. The operating theatres are one of the places where medical accidents occur, especially affecting service quality. The surgical team is a substantial cause of medical incidents, possibly because of human mistakes, environmental, equipment, and system failures. Not all surgery departments will implement uniform working styles. The Hospital Authority may set a management plan to unify practice and to identity the problems faced. Therefore, the government and Hospital Authority should focus on human resources, especially in terms of professional training and retention of staff. After all, surgery is a task of teamwork.

The shortage of fossil fuel can be minimized by developing renewable energies such as biogas. The raw material of biogas can be derived from corn stover. Biogas was produced under solid-state anaerobic digestion (SS-AD) and liquid anaerobic digestion (L-AD). The objectives of this study were to compare the biogas yield and analyze the pH value and VS degradation. The results reported that the SS-AD generated a higher biogas yield than L-AD. SS-AD could improve the biogas yield of 71%. Both SS-AD and L-AD had a higher final pH than the initial pH. Moreover, the VS degradation was proportionate to the biogas yield. The highest VS reduction was achieved on SS-AD. Keywords: anaerobic digestion, biogas, liquid state, solid state, volatile solid, renewable energy

Cocoa is a commodity that has a high economic value. According to the 2013 FAO, Indonesia ranks third as the largest cocoa producing country in the world and accounts for 17% of world cocoa production with an area of 1,774,303.97 ha of plantations. In Lampung province, many cocoa farmers process their own garden products into dry cocoa using conventional processes and the results are judged to be less efficient so that the quality of the dried cocoa beans produced is not good. In the conventional drying process requires firewood up to 1 cubic, drying time is 10 hours, and cocoa must be stirred every 30 minutes. This study aims to redesign conventional cocoa dryers in one of Wiyono village's independent businesses to be better in terms of heat distribution, fuel consumption, and drying time. In this research, MATLAB computation and simulation software are used to simplify the design process. The design that was carried out only modified the existing dryer without changing the total dryer system by adding a heating pipe into the drying chamber to produce better quality cocoa. From the results of simulations that have been carried out on the longitudinal axis alignment pipe design, the results of heat distribution are more evenly distributed than that of the widest axis directional pipeline arrangement. With the design of the longitudinal axis arrangement of the pipe, an estimated drying time of 7.9 hours is obtained, fuel consumption is between 0.15-0.28 m3 firewood, and there is no need for stirring during the drying process.Keywords: Cocoa, redesign, dryer, MATLAB.
