We estimated risks of severe outcomes in 820,404 symptomatic paediatric COVID-19 cases reported by 10 European Union countries between August 2020 and October 2021. Case and hospitalisation rates rose as transmission increased but severe outcomes were rare: 9,611 (1.2%) were hospitalised, 640 (0.08%) required intensive care and 84 (0.01%) died. Despite increased individual risk (adjusted odds ratio hospitalisation: 7.3; 95% confidence interval: 3.3–16.2; intensive care: 8.7; 6.2–12.3) in cases with comorbidities, most (83.7%) hospitalised children had no comorbidity.

In recent years, the education sector has been a key player in nation- and state-building, a leading social institu- tion responsible for innovative human development, the formation of competitive human capital, so the leading task of the Ukrainian state was and remains a functioning and self-sufficient national education system. would progressive traditions of the past, correspond to new social relations and accumulate innovative potential for fur- ther development. However, despite a number of positive developments in national education in recent years, the historically accumulated inconsistency of domestic education and science with best European and world practice is still acute.

The article attempts to theoretically investigate the evolution of scientific views on the development and reform of education in Ukraine through the prism of publications of authors-researchers on the pages of the scientific professional publication «Pedagogical education: theory and practice. Psychology. Pedagogy» and the results of a comprehensive analysis of the state and development of national education for the 30-year period of indepen- dence of Ukraine, presented in analytical publications of the NAPS of Ukraine: White Book of National Education (2010), National Report on the state and prospects of education in Ukraine (2011, 2016, 2021). Attention is paid to the continuum of current problems in the educational sphere, assessment of the current state and short- term prospects of Ukrainian education and scientific substantiation of ways to modernize national education in the cross section of two planes — the position of leading NAPS scientists and practitioners.

Building the concept of research of evolution of views, ideas, positions, beliefs of educational community on actual questions of development of education through a prism of scientific publications of authors of the researched edition, we outlined for ourselves two strategic vectors of the analysis: features of formation of the national self- sufficient integral system of education of the sovereign country for the periods 2001-2010, 2011-2015 and 2016- 2021 and the analytical characteristic of a focus of scientific attention of educators-contributors of magazine

The Comparison between Empirical and Data-driven Computation in Predicting CO and NOx Emissions from Gas-Turbine-Based Power Plant
Authors: Wicaksono T. Y.
Published: December 2021

The demand for the energy has been significantly increased over years led by the growth of global population. By the signing of the Paris Agreement in 2015, countries pledged to reduce the greenhouse gas effect including gas emissions to prevent and mitigate the global warming. The emissions control from power generation has then become a serious concern for countries to achieve their target in reducing gas emissions. Besides, the emitted gas such as Nitrogen oxides (NOx) or Carbon Monoxide (CO) that are resulted from the combustion process of fossil fuels in power plants is harmful pollutants to the living organism. The presence of those gas emissions can be predicted using Predictive Emissions Monitoring System (PEMS) or Continues Emissions Monitoring System (CEMS) methods. Continuous Emissions Monitoring System is a system that was designed to monitor the effluent gas streams resulted from the combustion processes. However, this empirical method still has several constraints in predicting the gas emissions where in some cases, it produces significant errors that caused by some uncontrollable aspects such as ambient temperature, pressure and humidity that can lead to miscalculation of operational risks and costs. Solving this problem, we conduct a PEMS with data-driven approach. In this study, we used the 2011-2015 open data from gas-turbine-based power plants in Turkey to train and test several supervised methods as a practical application to predict gas concentration. Predictive Emissions Monitoring System (PEMS) offers more advantages than Continuous Emissions Monitoring System (CEMS) especially in economic aspects. The system will monitor and predict the actual emissions from gas-turbine-based power plants operation. The results of this study indicate that the data-driven approach produces a good RMSE value. By having the gas emissions predicted, a mitigation plan can be set and the operational costs in the following years can be optimized by the company
ISCA: Quick Real-Time Sand Potential Prediction Simulator based on Critical Drawdown Failure and Machine Learning Model
Authors: Biladi A. I.
Published: December 2021

Sand production is almost an inevitable problem in oil and gas production facilities. As the reservoir depletes, sand grains from the reservoir begin to flow into the wellbore, this can cause serious problems to the wellbore. Excessive sand production can eventually plug and erode tubing, casing, flowlines, and surface equipment or even lead to formation collapse. In general, once sand production has occurred and if it is not handled properly it can end the production life of a reservoir and wells. This problem mostly occurs in mature fields with marginal economics for workover. The more reasonable option is to predict or mitigate the sand production, which can help identify the most economical way of sand control methods at the early stage. Many conventional sand prediction techniques have been developed which are based on field observation and experience, laboratory sand production experiments, and theoretical or numerical modeling. These conventional techniques have proven their effectiveness, but to achieve them can be time-consuming and costly. In this paper, we try to predict sand production with high efficiency and accuracy by using a quick simulator. Integrated Sand Control Analysis or ISCA is a simple simulator to help predict early sand production based on critical borehole and calculate critical drawdown pressure prediction. ISCA is supported by several mathematical models that function to predict various types of formation. Integrated with Machine Learning makes ISCA also compatible with big data analysis. The results in this study show that the combination of Machine Learning and analytical model can achieve accuracy above 90% based on the comparison of laboratory results with software predictions. With a high level of accuracy results this software can be considered as a reliable tool to predict and analyze sand production.
Optimizing the Enhance Oil Recovery Method using Nanotechnology to Maximize Oil Production in Older Wells
Authors: Nur A.
Published: December 2021

The oil and gas industry is still the main pillar of energy availability in Indonesia. The decline of oil and gas production is certainly of great concern. Around 70% of the oil and gas availability in Indonesia is dominated by old wells. Enhanced Oil Recovery is a method used to increase oil reserves in old wells. However, it still needs to be developed to optimize the performance of this method so that the oil produced is more optimal. Nanotechnology is the manipulation of matter at the nanometer scale. The use of Nanotechnology in EOR can maximize the performance of this method because the materials used will more easily pass through the pores of the rock. This paper will discuss the comparison between the use of common EOR method and the use of EOR method using Nanotechnology in optimizing oil and gas production in old wells, selecting surfactants, advantages to be achieved, as well as opportunities and ways to minimize the challenges of using Nanotechnology in EOR method. The research method is based on collecting relevant information and published data from various reliable sources. The results of this study will provide information that is needed and in accordance with current field realities, including opportunities for applying Nanotechnology in EOR field based on comparison results, selecting suitable surfactants to be applied with Nanotechnology, benefits and ways to minimize challenges in applying Nanotechnology in EOR.
TOC Prediction Using Delta Log Resistivity, and Its Distribution in Cyclostratigraphy-INPEFA Trend in “S-Field”, Kutai Basin”
Authors: Kembuan B. B. S.
Published: December 2021

S field has unique geological conditions, with a depth of maturity around 800 meters based on geochemical analysis and classified as the shallowest in the Kutai Basin compared to other fields of around 4000 meters. This is caused by this field's geological conditions, which are influenced by the tectonic gravitational force from the north and the lifting of the middle Miocene formation from below. The study aims to have better understanding on the petroleum system using the ∆ Log R to analyse the source rock, to be integrated with the Cyclostratigraphy-INPEFA log to discover which cyclic deposition trend has the higher TOC (total organic carbon) accumulation. Determining the potential source rock with the rich TOC would help the finding of a new prospect reservoir for conventional or unconventional development. ∆ Log R is a practical method for predicting TOC and depth, applied in many fields with success stories. The research focuses on TOC prediction on a delta plain environment with abundant coal source rock using sonic, density, and neutron logs as porosity logs. Because most of the Organic Content is found in Non-Reservoir Rocks, Reservoir Rocks needs to eliminate Log-Gamma Ray as a lithological interpretation. Mature Organic Rocks with a high TOC value and excellent porosity will show high resistivity; this is because Kerogen, which is dominant in shale, validates this TOC prediction for geochemical analysis. Cyclostratigraphy-INPEFA log is generated from a particular formula based on cyclic deposition concept that refers to the orbital change that affects earth insolation. The phenomena cause the sea-level change (eustasy). When the sea level drops (cooling phase), the coarse sediment will be deposited., Whereas the finer sediment will be deposited when the sea-level rises (warming phase). This study shows that predicted TOC accumulation is much higher in the warming phase.
Reducing Uncertainties In Shear Wave Petrophysical Log Prediction By Using Deep Neural Network and Machine Learning Method
Authors: Abdurrachman M. F.
Published: December 2021

Shear-wave velocity (Vs) log is one of the essential petrophysical well logs for reservoir characterisation in oil and gas exploration. Unfortunately, only a limited number of wells have a ready-to-use shear-wave velocity log. The common way to predict Vs from a Compressional-wave velocity (Vp) log is using empirical equations such as Castagna’s mud-rock line or Greenberg-Castagna equation. However, these methods only work for a specific rock type and are inflexible as every area has a complex and unique petrophysical characteristic relationship. Therefore, the Machine Learning (ML) methods (e.g., Multiple-linear Regression, Polynomial Regression, Support Vector Regression (SVR), Decision Tree, Random Forest, and XGBoost) and the Deep Learning (DL) method (e.g., Deep Neural Network (DNN)) that are suitable for big data analysis are proposed to solve this problem. These proposed methods aim to generate a complex Vs prediction model from multiple log data that can be used for general purposes, either for shale, limestone, sandstone, or other rocks. The study shows that the DNN and XGBoost can generate Vs prediction model with a correlation up to 94% overall in the R2 metric score, better than the empirical calculation for either shale, limestone, sandstone, or other rocks.
Building Bridges: A Conversation between Friends, about Language, Laziness, and Long-distance Running

Published: December 2021

This conversation took place in a shared Google Doc over several occasions in April and early May 2021, between friends and colleagues, artists and writers, Hannah Clarkson and Matilda Tucker, in the context of an ongoing experiment in collaborative writing.
In their individual and collective practices, Clarkson and Tucker explore potential embodiments in language(s) of thinking and dwelling in the ‘here and elsewhere’ of places and spaces they may not physically be in, across cultural, geographical and/or emotional distance. They are interested in how language can be employed as a tool for empathy beyond concrete linguistic understanding; how translation as method opens up to modalities of fictioning and collective storytelling; and writing as an experiment in sharing everyday struggles and building collective narratives of care.
An attempt to bridge gaps between the here and elsewhere of Stockholm, Berlin and all the other places that in this time of pandemic we cannot be, the text below is not a conclusion but a conversation. It is a thinking out loud - or rather, on screen - together, on themes of language and translation; belonging and resisting; work and laziness; former and formless selves.

Tribological studies of different bioimplant materials for orthopedic application using Taguchi experimental design
Authors: Solanke Sachin , Gaval Vivek
Published: December 2021

In this research ball on disc wear tests have been carried out with ASTM G-99 standard at room temperature in simulated body fluid. The tribological property such as the coefficient of friction and wear weight loss was studied by using the Taguchi design of experiments. The design of the experiment was done using L8 orthogonal array to determine the collective contribution of the wear parameters. An analysis of variance demonstrated that the individual contribution of type of material factor was 97.15% and 66.66% for the coefficient of friction and wear weight loss respectively, which is the highest individual contribution as compared to other factors. It was concluded that the coefficient of friction and wear weight loss is mainly influenced by type of material factor. The analysis of the signal-to-noise ratio shows that the optimal coefficient of friction and wear weight loss was obtained with CoCrMo material at an applied normal load of 5 N with a sliding velocity of 0.05 m/s for a track diameter of 30 mm. To check the accuracy of results a confirmation test was carried out which indicates that predicted values are very close to the experimental values and the model is significant to predict the coefficient of friction. The results showed that the coefficient of friction and wear weight loss increases with increasing the applied load and sliding velocity. The microstructure of all substrates materials was analyzed using a scanning electron microscope. Wear track study showed that adhesive dominant wear mechanism for all four different substrate materials.
Wear and Friction properties of H-Al-17Si alloy with dry, lubrication and coated (DLC-Star) conditions under HFRR
Authors: Malleswararao.K N.D. , Niranjan Kumar I.N. , Nagesh BH.
Published: December 2021

Dry, lubrication (SAE15W40), and coated (DLC-Star) reciprocating tribological tests on rapid solidified AlSi17Cu3.5-4Mg0.6-0.8 alloy was conducted using a high frequency linear reciprocating rig (HFRR) at ambient temperature. The alloy fabricated with the rheo-stir squeeze casting procedure under T-6 condition. However, at different loading (0-30 N) conditions, wear and friction properties of rapid solidified H-Al-17Si alloy are investigated. It is observed that the lower friction coefficient value obtained for DLC-Star coated H-Al-17Si alloy compared to dry and lubrication conditions. Though, for dry and lubricated sliding, the obtained wear coefficient values are 2.9X10-3 mm3/N.m and 4.0X10-4 mm3/N.m. A lower coefficient of wear value of 5.4X10-5 mm3/N.m was recorded with DLC-star coating under dry conditions. The alloy wear coefficient values first increases with applied load (up to 20 N) and then decreases (20 N to 30 N). EDS, AFM surface roughness profilometer, SEM, and advanced metallurgical microscope (AMM) analysis techniques used for the characterization of surface morphologies. The developments in friction and wear coefficients were fundamentally ascribed to the dispersion and size of primary Si elements and the development of tribo-oxide films on the rapid solidified AlSi17 alloy coated (DLC-Star) surfaces.

Mathematics is central in school curricula around the world, yet outcomes are mixed at best. This is true both in relation to attitudes expressed towards mathematics, and in relation to observed assessment outcomes, showing how poorly individuals are prepared to use mathematics in a world in which the ability to do so is of increasing importance. Why? This essay uses some PISA 2012 mathematics outcomes to seek explanations and possible ways forward. The main message is that negative outcomes of school mathematics arise for a variety of reasons, and they can be reversed through deliberate and concerted action.

Posteriormente, obtenemos mediante un cuestionario, que de entre los criterios estéticos que aparecen en la literatura, el referido a la simplicidad es el que parece ser compartido por alumnos de educación secundaria con calificaciones académicas medias y bajas. Finalmente, observamos mediante un estudio de casos, que a través de contenidos matemáticos, en este caso las teselaciones del plano, se vislumbra en alumnos de educación secundaria la aparición de consideraciones y experiencias estéticas.The Role of Aesthetics in the Teaching and Learning of MathematicsWe present an exploration of the role of aesthetics in the teaching and learning of Mathematics. Firstly, we review the state of the issue. Subsequently, through a questionnaire, we obtain that among the aesthetic criteria that appear in the literature is the one related to simplicity that seems to be shared by high school students of middle and low academic qualifications. Finally, through a case study, we observe that through mathematical contents, in this case the tessellations of the plane, we see in students of high school the appearance of aesthetic considerations and experiences.Handle: http://hdl.handle.net/10481/48170WOS-ESCIScopus record and citations
Agrado y utilidad de las matemáticas en la formación inicial de maestros de educación primaria

Authors: Nortes Rosa , Nortes Andrés
Published: December 2021

Para conocer si a los estudiantes universitarios del Grado en Educación Primaria les agradan las matemáticas y las consideran útiles, realizamos un estudio donde se profundiza en dichas nociones. Para ello, se aplicó un cuestionario de agrado y otro de utilidad a una muestra de 976 estudiantes de segundo, tercero y cuarto curso, a lo largo de cinco cursos académicos. Los resultados muestran que agrado está por debajo de la puntuación neutral y utilidad la supera ligeramente. Además, destaca que a los hombres les agradan las matemáticas más que a las mujeres, aunque ambos las consideran útiles por igual.Liking and Usefulness of Mathematics in Primary Education Teacher TrainingIn order to know whether university students doing a Primary Teachers Training Degree like mathematics and consider them useful, 976 students from the second, third and fourth years were asked to complete a Liking and a Usefulness questionnaire across five academic years. The values obtained for the Liking questionnaire are below the neutral value while results for the Usefulness questionnaire are slightly higher, men like mathematics more than women do and both find them equally useful.Handle: http://hdl.handle.net/10481/48172WOS-ESCIScopus record and citations
The program Ethnomathematics: Cognitive, anthropological, historic and socio-cultural bases
Authors: D' Ambrosio Ubiratan
Published: December 2021

We discuss the concept of knowledge and the cognitive process backing the evolution of knowledge in the human species. This leads to a reflection about the meaning peace. In simple terms, peace is the capability of dealing with conflicts [which are unavoidable as a result of individual differences] without the resource to arrogance and to bigotry, which culminates in aggression and violent confrontation. A road to peace is the reformulation of education. A proposal of a new concept of curriculum is presented and there is a brief discussion of the Program Ethnomathematics as the realization of the proposal.El programa Etnomatemáticas: bases cognitivas, antropológicas, históricas y socioculturalesDiscutimos el concepto de conocimiento y el proceso cognitivo de soporte a la evolución del conocimiento en la especie humana. Esto conduce a una reflexión sobre el significado de paz. En términos simples, la paz es la capacidad de lidiar con conflictos [que son inevitables como consecuencia de las diferencias individuales] sin el recurso a la arrogancia y fanatismo, que culmina en agresión y la confrontación violenta. Un camino hacia la paz es la reformulación de la educación. Se presenta una propuesta de un nuevo concepto de currículo y hay una breve discusión del Programa Etnomatemáticas como la realización de la propuesta.Handle: http://hdl.handle.net/10481/53007doi:10.30827/pna.v12i4.7851Scopus record and citations
Componentes de conocimiento del profesor para la enseñanza de la resolución de problemas en educación primaria
Authors: Piñeiro Juan Luis , Castro-Rodríguez Elena , Castro Enrique
Published: December 2021

La importancia que presenta la resolución de problemas en la enseñanza y aprendizaje de la matemática es una premisa aceptada en la comunidad de educadores matemáticos. No obstante, los marcos que describen o caracterizan el conocimiento de los profesores sobre las matemáticas escolares han dado poca relevancia a este proceso. Partiendo de revisiones curriculares y teóricas, presentamos una organización del conocimiento del profesor de educación primaria sobre la resolución de problemas de matemáticas. En ella diferenciamos un conocimiento sobre la resolución de problemas del que emergen los componentes relativos al concepto de problema, proceso de resolución y disposición para afrontar un problema; y un conocimiento pedagógico sobre la resolución de problemas en el que distinguimos un componente referido al aprendizaje y otro a la enseñanza. Nuestra reflexión ratifica la idea que la naturaleza distinta de un proceso como la resolución de problemas provoca un conocimiento que los modelos han omitido.Teacher knowledge components for teaching problem solving in primary educationProblem solving is central in teaching and learning of mathematics, an accepted premise in the community of mathematics educators. However, the frameworks that describe or characterize teachers' knowledge have given little relevance to this process. Starting from curricular and theoretical revisions, we present a proposal of organization for the knowledge of primary teacher about problem solving. We differentiate a knowledge of the process from which the components related to the concept of problem, resolution process and disposition to face a problem emerge; and a pedagogical knowledge where we distinguish a component referring to learning and another to the teaching of problem solving. Our reflection confirms the idea that the different nature of a process such as problem solving, causes a knowledge that the models have omitted.doi: 10.30827/pna.v13i2.7876Scopus record and citations
Construcción del algoritmo de la división en estudiantes de cuarto año básico de una escuela chilena
Authors: Aravena Bauzá Angélica , Morales Soto Astrid
Published: December 2021

Desde un enfoque socioepistemológico, se presenta un estudio cualitativo cuyo objetivo fue develar, en los argumentos de los estudiantes de 9 años, elementos que permiten caracterizar el proceso de construcción del algoritmo de la división en el sistema de los números naturales. Para ello, se diseñó una situación, donde argumentaron y dieron significado al proceso de resolución de divisiones, y de problemas de reparto y agrupamiento. Los primeros hallazgos evidencian que la división como agrupamiento no la consideran división, solo reconocen esta como repartir en partes iguales; y que no consideraron el resultado como un solo número, sino como el producto del cociente con el divisor agregando el resto.Scopus record and citations
Idoneidad didáctica de procesos de instrucción programados sobre didáctica de la estadística
Authors: Ruz Felipe , Molina-Portillo Elena , Contreras José Miguel
Published: December 2021

Este trabajo presenta los resultados de la implementación de la Guía de Valoración de la Idoneidad Didáctica de procesos de Instrucción programados sobre Didáctica de la Estadística (GVID-IDE) en cuatro programas de asignaturas sobre didáctica o enseñanza de la estadística para profesores de matemática chilenos. Siguiendo una metodología cualitativa, y mediante un análisis de contenido, se identificó la presencia o ausencia de cada uno de los indicadores que conforman la GVID-IDE, en el marco de la Teoría de Idoneidad Didáctica. Se concluye que los programas tienen un grado de idoneidad alto para las facetas afectiva, interaccional y mediacional, pero solo alcanzan un grado medio en las facetas epistémica, cognitiva y ecológica.Didactical Suitability of Planned Training Processes on Statistical EducationIn this work, we present the results of the implementation of the Assessment Guide of Didactic Suitability of planned Instructional processes about Educational Statistics (AGDS-IES) in four Chilean training programs of teaching statistics for mathematics teachers. Following a qualitative methodology and through a content analysis, the presence or absence of each of the indicators that compose the AGDS-IES was identified, within the framework of the Didactic Suitability Theory. It is concluded that the programs have a high degree of suitability for the affective, interactional and mediational facets, but only with a medium degree in the epistemic, cognitive and ecological facets.doi: 10.30827/pna.v14i2.8897
Mathematics teacher's specialised knowledge of prospective primary teachers: An explorative study
Authors: Ferretti Federica
Published: December 2021

The importance of good mastery of specialised mathematics knowledge for mathematics teachers and prospective teachers is now recognised internationally. This paper presents an exploratory study aimed at investigating how mathematics education courses affect the Mathematics Teachers’ Specialised Knowledge (MTSK) of prospective primary teachers. A questionnaire was administered to a sample of 118 future teachers, and an analysis of their answers was carried out with the MTSK model. The research highlights positive feedback on the effectiveness of the mathematics education laboratory that was staged, and provides an outline of the beliefs and the knowledge of the prospective teachers.
