Authors: Falcão Paula , Souza Aline Batista de 
Published: March 2021

Desde o final de 2019, o mundo tem enfrentado uma das mais graves pandemias da História: a Covid-19. Os riscos de contaminação, a busca pela cura, a necessidade de isolamento social, os números de morte que crescem a cada dia. O mundo já havia passado por tudo isso em outras crises sanitárias, mas a atual tem particularidades: graças aos avanços tecnológicos e ao advento da internet, hoje vivemos em uma sociedade em rede, na qual os indivíduos estão conectados de maneira global e a informação circula intensamente por meio de dispositivos digitais. Com instituições em crise, autoridades perdem credibilidade e vivenciamos a Era da Pós-verdade, onde reinam as fake news. Neste trabalho, discutiremos esse cenário da desinformação, infodemia e desinfodemia e traremos, de maneira expositiva, diversas fake news disseminadas durante a pandemia no Brasil – coletadas em portais de notícias, entre março e setembro de 2020, e organizadas conforme categorização temática de Posetti e Bontcheva.
Covid-19 knowledge graphs in Health Communication and Information
Authors: Iliadis Andrew 
Published: March 2021

This commentary discusses recent developments in ‘knowledge graph’ technology over the course of the Covid-19 pandemic. Recently experiencing a surge in popularity, knowledge graphs are technologies that assist with data integration through structured metadata modeling. Researchers tag and collate vast amounts of diverse data using knowledge graphs, yet problems related to semantic drift and more salient issues related to the political economy of information and communication technologies persist. Researchers should anticipate that the semantics of these Covid-19 knowledge graphs can change over time. Equally important, researchers should also consider all stakeholders involved, including those stakeholders that might be excluded.

Évaluation des propriétés conservatrices des extraits des racines d’Echium vulgare et de Fredolia aretioides dans des formulations de shampoing avec et sans EDTA
Authors: Bentabet N. , Boucherit K. , Boucherit-Otmani Z. , Rahmoun N. 
Published: March 2021

Les conservateurs sont des produits chimiques ajoutés aux produits cosmétiques pour les protéger contre toutes contaminations microbiennes qui se produisent lors de la fabrication ou pendant leurs usages par les consommateurs.
Dans notre travail nous avons examiné l’efficacité de conservation des extraits des racines de Fredolia aretioides et d’Echium vulgare dans trois types de formulations de shampoing.
L’incorporation des extraits des flavonoïdes 1-butanol ou l’acétate d’éthyle des racines d’Echium vulgare à une concentration finale de 1 % dans nos formulations de shampoing a induit une réduction des inocula. Il est important de noter que les shampoings ainsi préparés sont conservés contre la prolifération des bactéries et des levures et répondent par conséquent, au critère A de la Pharmacopée européenne. Au contraire, comme pour les bactéries et les levures, le shampoing sans conservateur était un bon substrat de croissance.
De nombreuses publications ont rapporté l’effet synergique de l’EDTA avec des conservateurs synthétiques ou naturels. Les résultats que nous avons obtenus ont montré que cet agent chélateur utilisé à une concentration finale de 1 %, améliore nettement le pouvoir conservateur des deux extraits testés. La réduction des inocula est estimée à 103 au 7e jour du test sans aucune augmentation au 14e et 28e jours pour les bactéries et à 102 au 14e jour du test sans aucune augmentation au 28e jour pour les levures.

Published: March 2021

Introducción: Hasta la fecha no se ha podido establecer un consenso para definir de forma universal el Síndrome Metabólico (SM) en niños y adolescentes. En Paraguay, no ha sido documentada la variación de la frecuencia de SM en niños y adolescentes de acuerdo a las diferentes definiciones propuestas en la literatura.
Objetivo: Determinar la frecuencia de Síndrome Metabólico en niños y adolescentes de una escuela de la ciudad de Asunción utilizando 3 diferentes definiciones.
Materiales y Métodos: Se realizó un estudio de corte transversal en niños y adolescentes (9-13 años). Se recolectaron datos demográficos y mediciones antropométricas. Se extrajeron muestras de sangre en ayunas. Se analizó el colesterol total, triglicéridos, HDL-colesterol, LDL-colesterol y se midió la presión arterial. La frecuencia de SM se estimó a partir de las definiciones modificadas de la Federación Internacional de Diabetes (IDFmod), Programa Nacional de Educación sobre Colesterol (NCEPmod) y De Ferranti. El protocolo de estudio fue aprobado por el comité de ética de la FCQ-UNA Cod 340/17.
Resultados: Se analizaron datos de 76 niños y adolescentes (el 56% de sexo masculino), cuya edad promedio fue de 10,5 ±1,1 años. El 54% presentó sobrepeso y obesidad. La frecuencia de SM fue 5,26% según IDFmod, 7,89% según NCEPmod y 22,37% de según De Ferranti.
Conclusión: La frecuencia de SM fue mayor al emplear la definición propuesta por De Ferranti. Utilizar definiciones cuyos puntos de corte son más estrictos podría tener un efecto en términos preventivos al detectar precozmente a los niños y adolescentes en riesgo.

Authors: Han Jiatong 
Published: March 2021

The beat is a kind of behavioral communication in the action or reaction. The dramatic action and the reaction with dramatic conflict together construct a narrative beat, and the dramatic conflict is the basis for establishing the narrative beat. The narrative of movie scenes should revolve around the same drama task. The establishment of narrative beats within the scene makes the drama conflict of events progressive and escalating. The narrative beat is a strategy to grasp the narrative rhythm, a method to create suspense, and a way to lay out the structure of the story.

Published: March 2021

This paper examined throughput optimization issue in wireless mesh network (WMN), the weakest point of this network in regard to this matter. A number of previous studies on this issue have been conducted, but most focus has been on general wireless network, only few studies so far have attempted on this network. This research aimed to optimize the CARA rate adaptation control algorithm in WMN network. The optimization was performed by adjusting the successtreshold and timeout parameters in the CARA algorithm to obtain an optimal throughput. The optimal result is showed that the optimal points of the success threshold and timeout are at range of 30-35. It is obviously seen in grid 4×5 and 5x5 where the throughput value of the optimization result continues to increase. Moreover, by adding the data transmission time for 100 seconds on grid 5×5 resulting the throughput value of 0.52206412 Mbps and after the optimization the throughput value increases up to 117% to 1.1350768 Mbps, when the success threshold and timeout value are 30. For an additional 150 seconds, the throughput value is 0.5074419333 Mbps and after the optimization the throughput increases up to 120% to 1.1211402 Mbps, when the success threshold and timeout value are 35.

Published: March 2021

Cibaligo River is the polluted rivers in Cimahi City. The river that flows through three districts and 6 sub-districts in Cimahi City catchment area of 666.19 hectares of watershed with a total length of 7 km. The land use of the district through which this river passes is domestic, trade, agriculture, livestock and industry whose waste will end into the Cibaligo River. The impact of these activities causes the river to be polluted and a decrease in water quality. The purpose of this study was to determine the status of water quality from upstream to downstream which represents the transition, dry, and rainy seasons. Knowledge of water quality status can be used as basic data for controlling water pollution in rivers. The pollutant index (IP) method used in this study is in accordance with the Decree of the State Minister for the Environment Number 115 of 2003 concerning guidelines for determining water quality status. The results showed that the water quality status of the Cibaligo River from upstream to downstream represented that each season was categorized as heavily polluted with the highest index value being in the rainy season at the downstream point. The main contributor that causes river water to be heavily polluted is domestic wastewater, especially the presence of total coliform and fecal coliform that exceed the established quality standards. Based on the results of the research, efforts to tackle domestic waste are needed to improve the quality of this river water.

Inductor with a metal core is a component which is almost always present in the daily electronic device known to us . To further prove the potential of the proposed new metalcore material, it is necessary to test the voltage variation, winding, and frequency in the inductor with the newly proposed metallic core material. The research method uses experimental methods. Three basic metal materials were used in the experiment, those are Cast Iron ASTM A48 (C 3.4%, Mn 0.5%, Si 1.8%,), Nicromine (Ni 80%, Cr 20%), Monel Alloy 400 (Ni 63%, Cu 31.7%, C 0.3%, Fe 2.5%, Si 0.5%, Mn 2%, S 0.024%). Experimental tests on these new types of metal were also carried out under various stress, winding, and working frequency conditions. The voltage variation selected is 4.5 V - 24 V, the winding variations and frequencies selected are 150 to 1000 turns and 50 Hz. The greatest inductance was obtained from ASTM A48, Fe, Monel Alloy 400, Nikromic, and without metallic core on the specified indicator variables. As the voltage increases and the number of turns increases, the inductance value increases.

Low Heart Rate Variability Predicts Stroke and Other Complications in the First Six Postoperative Months After a Hip Fracture Operation
Authors: Ernst Gernot , Watne Leiv Otto , Frihagen Frede , Wyller Torgeier Bruun , Dominik Andreas , Rostrup Morten 
Published: March 2021

Background: One-year mortality after hip fractures is underestimated and is reported as 25%. An improved risk stratifying could contribute to a better follow up of these patients. Heart Rate Variability (HRV) is an easy point-of-care investigation and is been used in cardiology, endocrinology, and perioperative care. This observational study intended to explore relevant associations between HRV parameters and 6-months mortality and morbidity after a hip fracture.Methods: One hundred and sixty-five patients admitted to two hospitals were included, and short-time HRV measurements (5 min, and 10 min at the two hospitals, respectively) were obtained. Mortality data were gathered by means of the Norwegian central address register. Patients, close relatives of patients, and in some cases their general physicians or nursery home physicians were interviewed 6 months postoperatively regarding the incidence of pneumonia, cardiac events, or stroke.Results: One and hundred fifty-seven (95.2%) patients were followed up after 6 months post-surgery. Twenty-one (13%) died during this period. Twenty patients (13%) developed pneumonia, eight (5 %) stroke, and four (2%) myocardial infarction. No HRV parameter was associated with 6-month general mortality. However, patients who developed stroke had significantly lower High Frequency Power (HF, p &lt; 0.001) and lower Very Low Frequency Power (VLF, p = 0.003) at inclusion compared to patients without complications. Patients who developed pneumonia had at the inclusion lower root mean square of successive differences (RMSSD, p = 0.044). Patients with a history of coronary heart disease (n = 41) showed a mortality of 7%. Mortality in this group was associated with standard deviation of beat-to-beat intervals (SDNN, p = 0.006), Total Power (TP, p = 0.009), HF (p = 0.026), and Low Frequency Power (LF, p = 0.012). Beta-blocker intake was associated with lower heart rate, but not with differences in HRV parameters.Conclusion: In this exploratory study, we present for the first-time significant associations between different preoperative HRV parameters and stroke, myocardial infarction, and pneumonia during a 6-month period after hip fracture. HRV might be a simple and effective tool to identify patients at risk that would warrant better follow-up.
