Pensamiento computacional, innovación y perspectivas interdisciplinarias en ámbitos educativos
Authors:   , Gómez Noelia Soledad
Published: December 2020

El abordaje de la relación entre tecnologías, educación y comunicación, pretende generar un análisis interdisciplinario sobre pensamiento computacional en los sistemas educativos y su tratamiento en el desarrollo de políticas públicas. Se analizan los documentos marco de políticas educativas de la Unión Europea, entendidos como base de las políticas de sus países miembros. Se identifica su impacto en dos casos puntuales: Reino Unido y España. El criterio de selección de estos casos tiene que ver con su relevancia y temporalidad. En el primer caso, se reconoce al Reino Unido como país pionero en la implementación y curricularización de contenidos relacionados al pensamiento computacional en su sistema educativo. En el caso de España, además de ser uno de los países de habla hispana dentro de la Unión Europea, constituye un caso reciente de incorporación de contenidos de Ciencias de la Computación en escuelas públicas. Esta investigación realiza una sistematización rigurosa sobre pensamiento computacional, así como el desarrollo de un trabajo interdisciplinario de articulación entre los campos disciplinares de comunicación, pedagogía e informática que contribuya al análisis del pensamiento computacional como competencia compleja para pensar, no solo las formas de su enseñanza, sino el impacto y su incidencia dentro de los procesos educativos.
Producción de material multimedia interactivo con contenido en Química General
Authors:   , García Ricardo José
Published: December 2020

La incorporación e integración de material multimedia en escenarios educativos, abre la posibilidad de cambio y renovación en el funcionamiento del aula, en los procesos didácticos, en la infraestructura necesaria, en la actividad del docente y el rol del alumno (Salinas, 2004) El uso de estos recursos incide sobre los procesos cognitivos, incrementando la capacidad para codificar, almacenar y procesar la información (Bartolomé, 2000). En este marco se muestra relevante el diseño y desarrollo de materiales educativos digitales para integrarlos a diferentes contextos y paradigmas. La adecuada complementación entre los conocimientos tecnológicos, disciplinares y didáctico–pedagógicos de los diseños, las tendencias y experiencias que permiten validar su efectividad, son consideraciones a tener en cuenta a la hora del diseño de estos materiales multimediales. La búsqueda bibliográfica revela que se investigan las metodologías que permiten llevar adelante estos diseños, las herramientas de autor vinculadas al desarrollo, los formatos y los estándares para estos materiales (Ponzio, 2012). También se investiga específicamente, el uso de materiales educativos digitales orientados a la enseñanza y el aprendizaje de las Ciencias en general y de la Química en particular, con el propósito de asistir al docente en el tratamiento de determinados contenidos (Dell´Arciprete, 2013). En el área de las Ciencias se analiza, como aporte al aprendizaje, las posibilidades que ofrecen los laboratorios virtuales y remotos, como escenarios de sumo interés en el campo educativo. Están basados en procesos de simulación que evitan los riesgos de la manipulación de material peligroso, la limitación de los costos y la ausencia de infraestructura, rompiendo las barreas de accesibilidad y espacio – tiempo, fortalezas muy apreciadas en muchos casos (Akbar, 2013). Se proponen también herramientas para la evaluación de la calidad de sistemas/programas/ cursos a distancia, como la herramienta web basada en el modelo ECALEAD denominada Web ECALEAD de mucha utilidad a la hora de desarrollar e implementar estos materiales (Gorga, 2013). Las experiencias de diseñar e incluir materiales hipermediales en contextos educativos, han sido exitosas y se continúan desarrollando, mejorando e implementando. En este contexto, se llevará a cabo un trabajo basado en dos etapas. La primera etapa, contempla una revisión bibliográfica de antecedentes y experiencias de uso de materiales hipermediales para la enseñanza y aprendizaje de la Química y de las herramientas de autor para el diseño de materiales digitales. La segunda etapa se enfoca en el diseño e implementación de un material educativo digital para el aprendizaje de contenidos de Química General. Se espera que el material educativo obtenido resulte de utilidad para la enseñanza y el aprendizaje de los temas abordados.

Determination of regional earthquake parameters from surface wave records
Authors: Fomochkina Anastasiya , Bukchin Boris
Published: December 2020

We consider in this paper the possibility of the source models construction for two regional earthquakes: in Akaba (June 27, 2015, Mw=5.5) and in the Dead Sea region (July 4, 2018, Mw=4.8) by surface wave records analysis. Fundamental Love and Rayleigh modes recorded by seismic networks IRIS, GEOSCOPE, and GEOFON were used for this purpose. At the first stage, at zero approximation we describe the source by moment tensor, considering the instantaneous point shear dislocation (double-couple) at a given depth. Four equivalent solutions were obtained from the amplitude spectra of surface waves. For an unambiguous choice of a solution, additional data were used, such as the signs of the first P-wave arrivals (for the Aqaba earthquake) or phase spectra (for an earthquake in the Dead Sea) were calculated for each of the four solutions. Based on the minimum values of the constructed joint residuals, a unique solution was chosen for each event. Then, considering the source flat, the following integral parameters were obtained: the duration of the process in the source, the lengths of the major and minor axes of the source, the average instant centroid velocity, the angle between the major axis of the source and the axis of the strike, the angle between the direction of motion of the instant centroid and the axis of the strike. The quality of the obtained solutions is estimated using the normalized residual function. This function characterizes the difference between the theoretical amplitude spectra and the observed ones. In the case of the earth-quake in the Dead Sea, the resolution of this function for some parameters was so small that it was not possible to obtain a solution. Also, for the earthquakes under consideration, the ambiguity associated with a significant excess of the surface wavelengths over the depth of the shallow source was analyzed
Refinement of the velocity section sedimentary stratum by the Nakamura method at new seismic stations of the IDG RAS
Authors: Tarasov Stanislav , Goev Andrey , Volosov Sergey , Gorbunova Ella , Ivanchenko Galina , Korolev Sergey
Published: December 2020

In 2017, as part of a project to study the deep structure of the central part of the East Europe-an platform, IDG RAS staff installed a sub latitudinal seismic profile of about 500 km in length, consisting of six stations. To successfully solve the problem of restoring a deep velocity section, the fullest possible information is needed on the velocity characteristics of the sedimentary sequence and, in particular, the first 0.5-1 km. Despite the considerable knowledge of the geological structure of the Moscow syneclise, information about its speed structure is based on interpolation and is fragmentary in nature. The paper presents the results of studies of the upper part of the sedimentary cover of the central part of the East Eu-ropean Platform (EEP) according to the data of the new network of broadband seismic stations IDG RAS. Using seismic noise records for each station, the dominant frequency peaks were obtained by the Nakamura method. For the Mikhnevo and Shatura stations, based on the data of deep drilling, it was established that the dominant peak corresponds to the boundary of the Upper Devonian - Lower Carbonian sediments. The obtained results make it possible to trace the occurrence of the indicated boundary along with all stations of the network along with the sublatitudinal profile through the collision zone of the EEP.
Monitoring the dynamics of seismicity within the Kemin-Chilik zone, generating M≥8 earthquakes
Authors: Muratalieva Zhazgul , Omuralieva Aiymjan
Published: December 2020

The dynamics of seismic processes at the junction of the Tien Shan mountain building area and the Kazakh shield is presented in the paper. It is noted that the Tien Shan’s lithosphere over thrusts the Kazakh Shield’s lithosphere, and the Kazakh Shield’s lithosphere under thrusts beneath the Tien Shan’s lithosphere based on the seismic tomographic and seismotectonic data. Low-velocity heterogeneity is distinguished at the junction of these lithospheres, under where a low-velocity anomaly flow is assumed in the mantle. Marginal (active structures of the Ili basin, Zaili mountain range), and middle (active structures of the Kemin, Chilik basins, Kungei mountain range) subzones with characteristic seismicity and seismic regimes are formed here. Seismogenic zones are distinguished (from north to south): Predzaili, Kemin-Chilik, Predkungei. Powerful earthquakes with M>8 occur in the Kemin-Chilik seismogenic zone (about 250 km long and up to 25 km wide), and earthquakes with M=7-8 - in the Predza-ili and Predkungei seismogenic zones. The dynamics of the earthquakes’ sequence is predetermined by the dynamics of the hierarchy of faults and blocks in the junction zone. The sequence of earthquakes is expressed by the hierarchy of seismic cycles. Seismic activation period, a peak of seismic activation, a period of seismic activation’s decay, and seismic calm period are distinguished in every cycle. Strong earthquakes take place in a first-order cycle with a long period, significant and small earthquakes - in cycles with corresponding short periods. The seismicity level of the study area is determined by the trajectory of the seismic cycles’ association. Dynamic segmentation and dynamic sectorization, vectors of seismic activity directed from the east and west to the highly compressed central part of the region are noted in the spatial and temporal distribution of earthquakes at the junction of the Tien Shan and the Kazakh shield.
Non-anticipative strategies in guarantee optimization problems under functional constraints on disturbances
Authors: Gomoyunov M.I. , Serkov D.A.
Published: December 2020

For a dynamical system controlled under conditions of disturbances, a problem of optimizing the guaranteed result is considered. A feature of the problem is the presence of functional constraints on disturbances, under which, in general, the set of admissible disturbances is not closed with respect to the operation of “gluing up” of two of its elements. This circumstance does not allow to apply directly the methods developed within the differential games theory for studying the problem and, thus, leads to the necessity of modifying them appropriately. The paper provides a new notion of a non-anticipative control strategy. It is proved that the corresponding functional of the optimal guaranteed result satisfies the dynamic programming principle. As a consequence, so-called properties of $u$- and $v$-stability of this functional are established, which may allow, in the future, to obtain a constructive solution of the problem in the form of feedback (positional) controls.
Dynamics of a pair of point vortices and a foil with parametric excitation in an ideal fluid
Authors: Bizyaev I.A. , Mamaev I.S.
Published: December 2020

In this paper we obtain equations of motion for a vortex pair and a circular foil with parametric excitation due to the periodic motion of a material point. Undoubtedly, such problems are, on the one hand, model problems and cannot be used for an exact quantitative description of real trajectories of the system. On the other hand, in many cases such 2D models provide a sufficiently accurate qualitative picture of the dynamics and, due to their simplicity, an estimate of the influence of different parameters. We describe relative equilibria that generalize Föppl solutions and collinear configurations when the material point does not move. We show that a stochastic layer forms in the neighborhood of relative equilibria in the case of periodic motion of the foil's center of mass.
Nonintegrability of the problem of a spherical top rolling on a vibrating plane
Authors: Kilin A.A. , Pivovarova E.N.
Published: December 2020

This paper investigates the rolling motion of a spherical top with an axisymmetric mass distribution on a smooth horizontal plane performing periodic vertical oscillations. For the system under consideration, equations of motion and conservation laws are obtained. It is shown that the system admits two equilibrium points corresponding to uniform rotations of the top about the vertical symmetry axis. The equilibrium point is stable when the center of mass is located below the geometric center, and is unstable when the center of mass is located above it. The equations of motion are reduced to a system with one and a half degrees of freedom. The reduced system is represented as a small perturbation of the problem of the Lagrange top motion. Using Melnikov’s method, it is shown that the stable and unstable branches of the separatrix intersect transversally with each other. This suggests that the problem is nonintegrable. Results of computer simulation of the top dynamics near the unstable equilibrium point are presented.

Comportamento sexual
Authors: Jesus Maria Cristina Pinto de , Machado Vanessa Nascimento , Machado Daniela Nascimento
Published: December 2020

O presente estudo foi realizado pelo Programa de Iniciação Científica da Universidade Federal de Juiz de Fora, Minas Gerais, e bus- cou a compreensão do vivido concreto de pessoas contaminadas pelo HIV, em relacionamentos sexuais. Foram realizadas entrevistas fenomenológicas com pessoas que compareceram ao ambulatório do Hospital Universitário para receber medicação, buscando-se a compreensão do significado de seu comportamento motivacional frente à vida sexual. As seguintes questões foram colocadas para os sujeitos participantes: Como você se contaminou com o vírus da AIDS? Hoje em dia, como você age nas relações sexuais e o que você tem em vista? As descrições foram analisadas na perspectiva da Fenomenologia Social de Alfred Schütz, tendo emergido as categorias Doença e Vida sexual que caracterizaram a ação dos sujeitos frente à vida sexual como sendo, a princípio, de negação sobre a fatalidade do HIV, mas, no que diz respeito aos relacionamentos íntimos a pessoa deseja ser aceita, embora refira-se à restrição da vida sexual por medo de contaminar o outro, ser contaminada e ser discriminada.
Uma ótica das disfunções da excitação sexual
Authors: Kreutz Carla Meira , Müller Alberto
Published: December 2020

O presente artigo objetiva uma revisão de estudos sobre a sexua- lidade humana como produto da interação dos sistemas biológico, psi- cológico e social e discute possibilidades terapêuticas nos transtornos se- xuais. Inicialmente, percorre-se a história da sexologia clínica. Em seguida, discute-se a relação custo-benefício de um diagóstico sexológico em nível de atenção primária. Revisa-se também o que é dito sobre as fases biológicas da resposta sexual humana com vistas a uma melhor com- preensão da patologia. Definem-se então os transtornos da excitação sexual feminina e masculina, considerando algumas possibilidades terapeúticas no manejo das disfuncionalidades. Por fim, apresenta-se um caso clínico de disfunção da excitação sexual masculina (disfunção erétil). As conclusões obtidas apontam para uma terapêutica interdisciplinar. Nessa, deve haver uma atenção tanto aos aspectos orgânicos quanto aos emocionais, contrapondo-se a uma cisão do ser em mente e corpo e uma atenção tanto à disfunção quanto à subjetividade do iudivíduo, não o reduzindo ao seu diagnóstico.

Trata-se de um estudo descritivo, exploratório realizado em uma escola pública de Juiz de Fora cujo objetivo principal foi verificar a opinião de escolares adolescentes da 6ª série do 1° grau, sobre a edu- cação sexual realizada pelos pais a pela escola. Por meio de um questionário semi-aberto buscou-se a caracterização dos adolescentes, suas experiências vividas; nível de diálogo com os pais; opiniões sobre a par- ticipação da escola na educação sexual. Os resultados mostraram que adolescentes, em sua maioria, na faixa etária de 12 anos relataram já terem interesse Pelo outro e que receberam as primeiras informações sobre sexo com amigos da mesma idade. O nível de diálogo com pais e professores é pequeno, embora, a maioria desses adolescentes considera que os pais deveriam conversar abertamente sobre o assunto com os fi- lhos na adolescência e que a escola e o lugar apropriado para comple- mentar a educação sexual realizada pela família. Constatou-se caber aos pais, a realização da educação sexual dos filhos, constituindo-se parte integrante da educação global, portanto, a Escola deveria auxiliá-la nessa tarefa.

Authors: Shkurupii Dmytro Anatoliovich , Kholod Dmytro Anatoliovich
Published: December 2020

Vascular catheters installation is most frequently used in critical care units. A node in the catheter lumen is a rare mechanical complication of the central venous catheterization. The 14-year-old was treated for acute appendicitis complicated by diffuse purulent peritonitis. It was decided to install a central venous catheter on the very first day of treatment. A catheterization of the right subclavian vein according to Seldinger was carried out. The catheter functioned properly for 6 days. On the 7th day, in the process of removal of the catheter, its extraction was blocked at a 1 cm depth from the tip. The catheter was removed by strong physical force with the occurrence of a hematoma in the area of installation of the catheter. Once removed, on the catheter there was found a node, formed inside the vessel. In this case, no disabling and life-threatening complications as a result of the use of the catheter were recorded. In the future, the patient was discharged recovered.

Modified thoracolumbar interfascial plane block versus epidural analgesia at closure for lumbar discectomy: a randomized prospective study
Authors: ÇELIK Erkan Cem , EKINCI Mursel , YAYIK Ahmet Murat , AHISKALIOGLU Ali , AYDI Muhammed Enes , KARAAVCI Nuh Cagri
Published: December 2020

Background & objective: The postoperative period of lumbar discectomy surgery usually involves a period of moderate to severe pain if adequate pain management is not practiced. Various pain controlling methods have been used other than oral and/or parenteral analgesic administration. We aimed to examine the effect of epidural analgesia at closure (EAC) versus modified thoracolumbar interfascial plane (mTLIP) block on postoperative opioid consumption in patients undergoing lumbar discectomy.

Methodology: It was a randomized, prospective study involving sixty adult patients undergoing single-level lumbar discectomy. Patients were randomly assigned to two groups. mTLIP group (n=30) received ultrasound-guided bilateral mTLIP block with 20 ml of 0.25% bupivacaine. EAC group (n=30) received 20 ml of 0.25% bupivacaine to the epidural space by the surgical team at the closure stage of surgery. Postoperatively, analgesia was performed with intravenous tramadol with a patient-controlled analgesia (PCA) pump. Visual analog scale (VAS) scores, opioid consumption, rescue analgesia and side effects were recorded.

Results: Groups had similar demographic measures. There was statistically no difference in terms of opioid consumption from zero to 4th hr and VAS scores in the 1-2 hrs postoperatively (p > 0.05) between groups. At 4-12 hrs and 12-24 postoperatively hrs intervals, total opioid consumption was significantly lower in Group mTLIP compared to Group EAC (p < 0.05). At the 4th, 8th, 12th, and 24th hrs VAS scores were lower in Group mTLIP compared to Group EAC (p < 0.05). Rescue analgesia usage was significantly higher in the Group EAC than in the Group mTLIP, e.g. 11/30 vs. 3/30 respectively (p = 0.015).

Conclusion: Preoperative bilateral, ultrasound-guided modified thoracolumbar interfascial plane block offers more effective postoperative analgesia, thus reducing tramadol consumption as compared to epidural analgesia at closure after lumbar discectomy surgery.

SEPARATING THE TERRAIN COVER OF IRAQI MARSHES REGION USINQ NEW SATELLITE BAND COMBINATION
Authors: & Naji Abduljabbar
Published: December 2020

A band combination (542) has been adopted and applied as a new method to classify the Iraqi marshes regions which they are located in the southern of Iraq using Landsat-5 TM scene. The results of proposed band combination were compared to the standard band combinations which they are selected to classify scene classes (541, 543 and 742). In addition, the results reveal that the standard band combinations are failed to discriminate between the scene classes that due to the aquatic nature of the scene, which makes the spectral response of the different classes very close, thus, they miss-classify the scene. Furthermore, the green band which was used in the proposed band combination enhanced the spectral response to discrimination between the different land cover classes. It was found that the support vector machine technique that performed to classify the scenes was revealed to be a very good classifier. The contribution of this study is obvious as the resulting outcomes can be capitalized as guidelines to separate the land cover classes in the aquatic nature to an accuracy that has been reached to 98% compared with the scene’s region of interest.

THALASSEMIA -AN OVERVIEW
Authors: Gupta Muskan
Published: December 2020

Thalassemia is a hereditary disorder found on chromosome 11 and chromosome 16, caused due to point mutation/insertion/deletion. It is one of the most prevalent single gene disorder found in the Indian population with a carrier frequency of 3-4%. The individuals are categorized into 3 types: homozygous, heterozygous and compound heterozygous. Where heterozygous individuals are normally carriers and homozygous and compound heterozygous are affected. The severity of this disorder lies on what type of mutation the gene carries. Previous studies showed the use of ARMS-PCR for the detection of targeted mutations and other showed the use of Sanger’s sequencing for the study of the mutation. Some new or rare mutations can also be detected through Sanger Sequencing and can help in studying the spectrum of the gene. The Clinical treatment involves blood transfusion or allogeneic stem cell transplant. There are lots of complications arising during treatment such as iron overloading. Detection of mutation in the family helps in prenatal testing to prevent the birth of affected children in the family.

converters is carried out. The proposed control method is based on the
modulation of the effective filter inductance of the converter when operating
in discontinuous conduction mode (DCM). It is well known that the output
characteristic of a HS DC-DC converter operating in DCM is dependent on the
effective inductance of the output filter. This way, by using a variable
inductance the output of the converter can be controlled. The proposed control
method can be applied to any converter topology, namely buck, boost,
buck-boost, flyback, forward, and so on. In this paper, the operation of the
buck converter with MC is investigated in detail as a case study. This work
proves that the proposed control method can be effectively used to control
DC-DC converters on its own or by combination with other control parameters as
duty cycle and/or frequency. An experimental prototype has been built to test
the proposed control method and modeling process and to demonstrate its
feasibility and possibilities.

Introduction

Due to the complex nature of cancer cases, it is imperative that the involved healthcare providers coordinate the patients care plan in union to reach the best possible outcome in the smoothest and fastest manner. This is what multidisciplinary tumor board (MTB) meetings strive to achieve. Conducting regular MTB meetings requires significant investment of time and finances. It is thus vital to assess the empirical benefits of such practice.

Methods

A meta-analysis was conducted to evaluate the literature regarding the impact of MTB meetings on patient 5-year survival. Relevant studies were identified by searching Ovid MEDLINE and Embase databases from January 1995 to July 2019. Studies were included if they assessed 5-year survival in cases discussed in MTB meetings and used a comparison group and/or a pretest and posttest design.

Results

Five articles met the study's inclusion criteria. Quality of studies was affected by selection bias and the use of historic cohorts. The results showed significantly improved 5-year survival in the MTB group compared with the non-MTB groups (odds ratio for 5-year death rate of 0.59, CI 0.45–0.78, p < 0.001).

Conclusion

This meta-analysis showed that cancer MTB meetings have a significant impact on patients' 5-year survival. This could be because of several reasons, such as less time to treatment initiation, better adherence to guidelines, higher numbers of investigational imaging, lesser surgical complications, and recurrence rates. Future prospective studies are needed to further delineate reasons for improvement of outcome to enhance the benefits of this approach.

A cadeia produtiva do café no Brasil apresenta grande importância socioeconômica, gerando divisas, com grande capacidade geradora de empregos, que segundo o primeiro levantamento da safra de 2020 da Conab, o país deverá colher entre 57,15 e 62,02 milhões de sacas beneficiadas de café. Já no Estado do Espírito Santo, a produção prevista pela CONAB encontra-se entre 13,02 milhões e 15,44 milhões de sacas beneficiadas, sendo 30,84% desta de café arábica. A pesquisa na cafeicultura tem contribuído para o desenvolvimento de novas tecnologias, mas o tamanho de parcelas para experimentos com café é variável e baseado na maioria das vezes na experiência do pesquisador. Com isso, o objetivo do trabalho foi determinar os tamanhos ótimos de parcelas experimentais para avaliar características físico-químicas de café arábica, utilizando os métodos do modelo linear de resposta a platô, da máxima curvatura modificado e da comparação de variâncias. A modelagem aplicada neste estudo permite concluir que de acordo com os dados testados que: São necessárias pelo menos 7 plantas por parcela útil de café arábica para avaliar as características ATT, pH e compostos fenólicos totais, pelo método do modelo linear de resposta a platô; 6, 2 e 6 plantas por parcela experimental útil de café arábica para avaliar as características ATT, pH e compostos fenólicos totais, respectivamente, pelo método da máxima curvatura modificado; e para o método da comparação de variâncias são necessárias 4 plantas úteis por parcela experimental para as três características.

Os microrganismos atuam diretamente na qualidade da bebida do café, seja pela degradação de compostos presentes nos grãos ou pela excreção de metabólitos que difundem para o interior dos frutos. Portanto, o conhecimento dos microrganismos e seu papel na fermentação é de grande importância para se obter um produto de qualidade. A fermentação é utilizada para remover a camada de mucilagem aderida ao pergaminho do grão, com o potencial de melhoria da qualidade do café. Este estudo teve como objetivo avaliar a qualidade global do café em função de diferentes processamentos e tempos de fermentação. Para este estudo foram utilizados cafés cereja descascado e cafés cerejas naturais com fermentação espontânea e fermentações induzidas, nas quais foram inoculadas levedura e bactéria em tempos diferentes de fermentação. O estudo evidenciou que o uso de culturas starters durante a fermentação do café contribuiu para a obtenção de uma bebida de qualidade com características sensoriais aceitas pelos provadores, indicando que levedura Saccharomyces Cerevisae em ambiente anaeróbico e sem adição de água, melhorou significativamente a qualidade sensorial da bebida.

Published: December 2020

Large-scale production of parts from powders and powder steels, in which parts are shaped in presses is considered. The three processes for production of the parts are analyzed. At two of them preforms are formed from
the powder, they are sintered and the parts are punched from the sintered preforms. In the first process is used
hot forging, in the second process used cold forging. The advantage of cold forging is demonstrated. The durability of the tool during cold forming is not sufficient to produce of parts from powder steels. The ways to reduce of
stresses in the tool are described. The third process comprises forming from powder of the final shape parts and
their sintering. Such process is applied for parts from powder steels. However in this process the parts have large
porosity, which reduces their strength and reduces the efficiency of heat treatment. The method for reducing of the
parts porosity as they are formed is described.
