Revolutions Take Time
Authors: Wittenburg Peter , Strawn George
Published: November 2021

The 2018 paper titled “Common Patterns in Revolutionary Infrastructures and Data” has been cited frequently, since we compared the current discussions about research data management with the developments of large infrastructures in the past believing, similar to philosophers such as Luciano Floridi, that the creation of an interoperable data domain will also be a revolutionary step. We identified the FAIR principles and the FAIR Digital Objects as nuclei for achieving the necessary convergence without which such new infrastructures will not take up. In this follow-up paper, we are elaborating on some factors that indicate that it will still take much time until breakthroughs will be achieved which is mainly devoted to sociological and political reasons. Therefore, it is important to describe visions such as FDO as self-standing entities, the easy plug-in concept, and the built-in security more explicitly to give a long-range perspective and convince policymakers and decision-makers. We also looked at major funding programs which all follow different approaches and do not define a converging core yet. This can be seen as an indication that these funding programs have huge potentials and increase awareness about data management aspects, but that we are far from converging agreements which we finally will need to create a globally integrated data space in the future. Finally, we discuss the roles of some major stakeholders who are all relevant in the process of agreement finding. Most of them are bound by short-term project cycles and funding constraints, not giving them sufficient space to work on long-term convergence concepts and take risks. The great opportunity to get funds for projects improving approaches and technology with the inherent danger of promising too much and the need for continuous reporting and producing visible results after comparably short periods is like a vicious cycle without a possibility to break out. We can recall that coming to the Internet with TCP/IP as a convergence standard was dependent on years of DARPA funding. Building large revolutionary infrastructures seems to be dependent on decision-makers that dare to think strategically and test out promising concepts at a larger scale.
Operation Safety of a 2-DoF Planar Mechanism for Arm Rehabilitation

Published: November 2021

The operation safety of rehabilitation devices must be addressed early in the development process and before being tested on people. In this paper, the operation safety of a 2-DoF (degrees of freedom) planar mechanism for arm rehabilitation is addressed. Then, the safety and efficiency of the device operation is assessed through the Transmission Index (TI) distribution in its workspace. Furthermore, the produced stresses on the human arm are assessed via the FEM (finite element method) when the rehabilitation device reaches five critical positions within its workspace. The TI distribution showed that the proposed design has a proper behaviour from a force transmission point of view, avoiding any singular configuration that might cause a control failure and subsequent risk for the user and supporting the user’s motion with a good efficiency throughout its operational workspace. The FEM analysis showed that Nurse operation is safe for the human arm since a negligible maximum stress of 6.55 × 103 N/m2 is achieved by the human arm when the device is located on the evaluated critical positions.
Investigation on Aesthetic and Water Permeability of Surface Protective Material under Accelerated Weathering
Authors: Chen Feng , Quy Nguyen Xuan , Kim Jihoon , Hama Yukio
Published: November 2021

In this paper, experiments were conducted on the effects of aesthetic and durability of three representative surface protective material under accelerated weathering test for 5000 h. First, the adaptability of the surface protective material coating to the substrate was proven by examining the aesthetic properties and the water permeability of the building materials. Second, the pollutant resistance of the surface protective material coating to artificial stain was assessed using xenon-arc light. The result shows that the appearance of the silane types did not change significantly, and the water permeability was improved. In addition, the silicate types did not improve water permeability and the surface color was changed. Fluor- resin types effectively improved the water permeability, but the surface color became dark. Sample measurements showed changes in the average width of the contamination after weathering, with an increase after spray cleaning and ultrasonic cleaning. However, it was observed that after washing the pollution average width of all specimens due to weathering at 5000 h was almost as much or smaller than the initial value.

Published: November 2021

Injuries of the bone/cartilage and central nervous system are still a serious socio-economic problem. They are an effect of diversified, difficult-to-access tissue structures as well as complex regeneration mechanisms. Currently, commercially available materials partially solve this problem, but they do not fulfill all of the bone/cartilage and neural tissue engineering requirements such as mechanical properties, biochemical cues or adequate biodegradation. There are still many things to do to provide complete restoration of injured tissues. Recent reports in bone/cartilage and neural tissue engineering give high hopes in designing scaffolds for complete tissue regeneration. This review thoroughly discusses the advantages and disadvantages of currently available commercial scaffolds and sheds new light on the designing of novel polymeric scaffolds composed of hydrogels, electrospun nanofibers, or hydrogels loaded with nano-additives.
Co-Existence of Iron Oxide Nanoparticles and Manganese Oxide Nanorods as Decoration of Hollow Carbon Spheres for Boosting Electrochemical Performance of Li-Ion Battery

Published: November 2021

Here, we report that mesoporous hollow carbon spheres (HCS) can be simultaneously functionalized: (i) endohedrally by iron oxide nanoparticle and (ii) egzohedrally by manganese oxide nanorods (FexOy/MnO2/HCS). Detailed analysis reveals a high degree of graphitization of HCS structures. The mesoporous nature of carbon is further confirmed by N2 sorption/desorption and transmission electron microscopy (TEM) studies. The fabricated molecular heterostructure was tested as the anode material of a lithium-ion battery (LIB). For both metal oxides under study, their mixture stored in HCS yielded a significant increase in electrochemical performance. Its electrochemical response was compared to the HCS decorated with a single component of the respective metal oxide applied as a LIB electrode. The discharge capacity of FexOy/MnO2/HCS is 1091 mAhg−1 at 5 Ag–1, and the corresponding coulombic efficiency (CE) is as high as 98%. Therefore, the addition of MnO2 in the form of nanorods allows for boosting the nanocomposite electrochemical performance with respect to the spherical nanoparticles due to better reversible capacity and cycling performance. Thus, the structure has great potential application in the LIB field.
Spectral and Spatial Feature Integrated Ensemble Learning Method for Grading Urban River Network Water Quality
Authors: Zhou Xiaoteng , Liu Chun , Akbar Akram , Xue Yun , Zhou Yuan
Published: November 2021

Urban river networks have the characteristics of medium and micro scales, complex water quality, rapid change, and time–space incoherence. Aiming to monitor the water quality accurately, it is necessary to extract suitable features and establish a universal inversion model for key water quality parameters. In this paper, we describe a spectral- and spatial-feature-integrated ensemble learning method for urban river network water quality grading. We proposed an in situ sampling method for urban river networks. Factor and correlation analyses were applied to extract the spectral features. Moreover, we analyzed the maximum allowed bandwidth for feature bands. We demonstrated that spatial features can improve the accuracy of water quality grading using kernel canonical correlation analysis (KCCA). Based on the spectral and spatial features, an ensemble learning model was established for total phosphorus (TP) and ammonia nitrogen (NH3-N). Both models were evaluated by means of fivefold validation. Furthermore, we proposed an unmanned aerial vehicle (UAV)-borne water quality multispectral remote sensing application process for urban river networks. Based on the process, we tested the model in practice. The experiment confirmed that our model can improve the grading accuracy by 30% compared to other machine learning models that use only spectral features. Our research can extend the application field of water quality remote sensing to complex urban river networks.
High-Efficiency Multi-Sensor System for Chair Usage Detection
Authors: Baserga Alessandro , Grandi Federico , Masciadri Andrea , Comai Sara , Salice Fabio
Published: November 2021

Recognizing Activities of Daily Living (ADL) or detecting falls in domestic environments require monitoring the movements and positions of a person. Several approaches use wearable devices or cameras, especially for fall detection, but they are considered intrusive by many users. To support such activities in an unobtrusive way, ambient-based solutions are available (e.g., based on PIRs, contact sensors, etc.). In this paper, we focus on the problem of sitting detection exploiting only unobtrusive sensors. In fact, sitting detection can be useful to understand the position of the user in many activities of the daily routines. While identifying sitting/lying on a sofa or bed is reasonably simple with pressure sensors, detecting whether a person is sitting on a chair is an open problem due to the natural chair position volatility. This paper proposes a reliable, not invasive and energetically sustainable system that can be used on chairs already present in the home. In particular, the proposed solution fuses the data of an accelerometer and a capacitive coupling sensor to understand if a person is sitting or not, discriminating the case of objects left on the chair. The results obtained in a real environment setting show an accuracy of 98.6% and a precision of 95%.

Published: November 2021

Triage is the first interaction between a patient and a nurse/paramedic. This assessment, usually performed at Emergency departments, is a highly dynamic process and there are international grading systems that according to the patient condition initiate the patient journey. Triage requires an initial rapid assessment followed by routine checks of the patients’ vitals, including respiratory rate, temperature, and pulse rate. Ideally, these checks should be performed continuously and remotely to reduce the workload on triage nurses; optimizing tools and monitoring systems can be introduced and include a wearable patient monitoring system that is not at the expense of the patient’s comfort and can be remotely monitored through wireless connectivity. In this study, we assessed the suitability of a small ceramic piezoelectric disk submerged in a skin-safe silicone dome that enhances contact with skin, to detect wirelessly both respiration and cardiac events at several positions on the human body. For the purposes of this evaluation, we fitted the sensor with a respiratory belt as well as a single lead ECG, all acquired simultaneously. To complete Triage parameter collection, we also included a medical-grade contact thermometer. Performances of cardiac and respiratory events detection were assessed. The instantaneous heart and respiratory rates provided by the proposed sensor, the ECG and the respiratory belt were compared via statistical analyses. In all considered sensor positions, very high performances were achieved for the detection of both cardiac and respiratory events, except for the wrist, which provided lower performances for respiratory rates. These promising yet preliminary results suggest the proposed wireless sensor could be used as a wearable, hands-free monitoring device for triage assessment within emergency departments. Further tests are foreseen to assess sensor performances in real operating environments.
Water and the Circular Economy: Learning from Nature
Authors: Kakovitch Thomas S. , O’Hara Sabine
Published: November 2021

This paper examines the hydrological cycle and its implications for the production capacity of two countries, China and the United States. While it takes a macro-level view, it illustrates the relevance of understanding the circularity of nature as exemplified by the hydrological cycle, for urban and regional circular economy considerations. Taking the circularity of nature as a starting point is a departure from common circular economy conceptions, which take an anthropocentric perspective rather than a nature based one. We calculate the amount of solar energy available for freshwater evaporation and the allocation of freshwater to its key uses in the domestic, industrial, and agricultural sectors. Our calculations indicate that the capacity to generate economic output can be accurately described by the embodied solar energy distribution that determines the availability of freshwater for allocation to different uses. This illustrates the need to take environmental/physical conditions more fully into account in economic development decisions at every level, from local to regional, national, and global. We begin our analysis with a review of circular economy concepts and argue that they reveal a limited understanding of the circularity of nature evident in energy and material cycles and their economic capacity implications. Achieving further expansions of economic capacity may increasingly depend on an improved understanding of nature’s circularity, especially when competing resource pressures and land-use constraint exacerbate economic capacity limits. Our findings suggest three particularly important lessons for decision makers: first, the efficiency increases needed to realize growing economic output will require circular economy models that consider the efficient processing capacity of nature rather than relying solely on technological solutions; second, the non-use of resources may be as valuable or more than their use; and third, price policies can be effective in steering resource use and non-use in the right direction.
Tourism, Empowerment and Sustainable Development: A New Framework for Analysis
Authors: Scheyvens Regina , van der Watt Heidi
Published: November 2021

For over twenty years, tourism researchers have examined how to determine whether destination communities are being empowered through tourism: there is much we can learn through analysis of that work. We outline and critique the most commonly used empowerment framework in this field as was first published by Scheyvens in 1999, which has four dimensions (psychological, social, economic and political) but which has been adapted and extended in a variety of ways. We also consider two other frameworks, and the application of a revised model in the South African context, before proposing that the Scheyvens framework would be strengthened through the addition of environmental and cultural dimensions. We draw theoretical inspiration from nested circle approaches to sustainable development to embed the dimensions of community empowerment within a series of ‘enabling factors’ that might support possibilities for community empowerment to occur, and, in turn, the empowerment dimensions and enabling factors are situated within a wider circle of the natural environment. We have structured this all into a new Empowerment and Sustainable Development Framework.
Tin(IV) Compounds as Photo-Stabilizers for Irradiated Surfaces of Poly(Vinyl Chloride) Films
Authors: Mohammed Alaa , Kadhom Mohammed , Yousif Emad
Published: November 2021

Dimethyl-organotin(IV) valsartan (Me2SnL2) and dichlorostannanediyl valsartan (SnL2Cl2) complexes were synthesized, characterized, and applied as Poly(vinyl chloride) (PVC) photo-stabilizers. The complexes were loaded within the PVC films in a weight ratio of 0.5%, and the modified films were irradiated to a UV light of 313 nm wavelength for 300 h at room temperature. The efficiency of the complexes-filled films was compared with the plain one and evaluated before and after irradiation by Fourier transform infrared spectroscopy, weight loss, gel content, change in viscosity, atomic force microscopy, and field emission scanning electron microscopy. The SnL2Cl2 complex had higher activity than the Me2SnL2 complex to retard the PVC’s photodegradation by several mechanisms.
Multi-Tier Cellular Handover with Multi-Access Edge Computing and Deep Learning
Authors: Kapadia Percy , Seet Boon-Chong
Published: November 2021

This paper proposes a potential enhancement of handover for the next-generation multi-tier cellular network, utilizing two fifth-generation (5G) enabling technologies: multi-access edge computing (MEC) and machine learning (ML). MEC and ML techniques are the primary enablers for enhanced mobile broadband (eMBB) and ultra-reliable and low latency communication (URLLC). The subset of ML chosen for this research is deep learning (DL), as it is adept at learning long-term dependencies. A variant of artificial neural networks called a long short-term memory (LSTM) network is used in conjunction with a look-up table (LUT) as part of the proposed solution. Subsequently, edge computing virtualization methods are utilized to reduce handover latency and increase the overall throughput of the network. A realistic simulation of the proposed solution in a multi-tier 5G radio access network (RAN) showed a 40–60% improvement in overall throughput. Although the proposed scheme may increase the number of handovers, it is effective in reducing the handover failure (HOF) and ping-pong rates by 30% and 86%, respectively, compared to the current 3GPP scheme.

Lợn rừng, chó, mèo và chim ăn thịt bị nhiễm Trichinella do ăn xác, thịt động vật nhiễm Trichinella. Người bị nhiễm do ăn phải thịt tái/sống có ấu trùng Trichinela. Tỉnh Đắk Lắk có điều kiện khí hậu, phương thức chăn nuôi lợn và tập quán của người bản địa thuận lợi cho lưu hành Trichinella. Hiện tại, không có thông tin nào về sự lưu hành của Trichinella trên địa bàn tỉnh; do đó cần thiết xác định sự lưu hành Trichinella ở lợn trên địa bàn tỉnh Đắk Lắk. Sử dụng phương pháp xét nghiệm tiêu cơ cho mẫu cơ lấy từ 835 lợn nuôi nhốt, thả rông trên 3 huyện Buôn Đôn, Krông Năng và M’Drăk, kết quả cho thấy không xác định được mẫu nào có sự hiện diện của Trichinella. Tuy nhiên, bằng phương pháp tiếp cận Bayesian cho thấy tỷ lệ nhiễm thực Trichinella ở đàn lợn trên địa bàn tỉnh được ước tính dao động từ 0,38 (95% CrI: 0,02 - 1,29) đến 2,44% (95% CrI: 0,12 - 9,23%). Trong các nghiên cứu tiếp theo phương pháp chẩn đoán có độ nhạy cao cần được áp dụng để xác định chính xác hơn sự lưu hành của Trichinella trên địa bàn tỉnh Đắk Lắk.

TRANSDISCIPLINARY APPROACH IN FREE RADICAL THEORY OF AGING. CONTRIBUTION OF NIKOLAY M. EMANUEL AND HIS SCIENTIFIC SCHOOL TO GERONTOLOGY

Published: November 2021

Работа представляет собой обзор научных исследований влияния антиоксидантов-геропротекторов на старение экспериментальных животных и репликативное старение диплоидных клеток человека, выполненных в отделе кинетики химических и биологических процессов «ХИМБИО» Института химической физики АН СССР под руководством академика Николая Марковича Эмануэля в 1960- 1980- е гг. В работах Н.М. Эмануэля и сотрудников было установлено неизвестное ранее явление взаимодействия ингибиторов свободнорадикальных реакций в процессах окисления органических веществ, заключающееся в регенерации более эффективного ингибитора вследствие переноса атома водорода к его радикалу от молекулы менее эффективного ингибитора. Антиоксиданты поливалентны и могут влиять одновременно на многие процессы старения. Данные научной школы Н.М. Эмануэля по увеличению средней продолжительности жизни на 25,3 % и максимальной продолжительности мышей на 55,8 % под действием антиоксидантов, полученные в результате хорошо обоснованных экспериментальных и теоретических исследований, явились весомым аргументом в пользу свободнорадикальной теории старения.

The work is aimed to review the results of scientific studies of the effect of antioxidants-geroprotectors on the aging of experimental animals and the replicative aging of human diploid cells, carried out in the Department of Kinetics of Chemical and Biological Processes «KHIMBIO» of the Institute of Chemical Physics of the USSR Academy of Sciences under the leadership of academician Nikolay Markovich Emanuel in the 1960-1980s after pioneer work by D. Harman. By N.M. Emanuel and colleagues, it was established a previously unknown phenomenon of radical interaction of inhibitors in the oxidation of organic substances, which consists in the regeneration of a more effective inhibitor due to the transfer of a hydrogen atom to its free radical from a molecule of a less effective inhibitor. Antioxidants are polyvalent and can simultaneously affect many stages of aging processes. Data from the N.M. Emanuel scientific school on the increase of the average lifespan of mice by 25,3 % and their maximum lifespan by 55,8 % using antioxidants, discovered at the Institute of Chemical Physics of the USSR Academy of Sciences as a result of well-founded experimental and theoretical studies, became a powerful argument in favor of the free radical theory of aging in 1970-ties. This was further promoted by approaches based on the theory of reliability, the damage theory, and as well as an approach based on oxidative activation of the Nrf2 signaling pathway, which maintains the «nucleophilic tone» of protective oxidoreductases.

A pregnant woman often experiences many changes, both physical changes and psychological changes. This condition will always cause a feeling of physical discomfort to the pregnant woman, coupled with an image of the delivery process, how the baby is and the condition of the baby after birth. Such images are common in pregnant women who are about to undergo labor. Conditions like that can cause feelings of anxiety in pregnant women, especially in women who are pregnant for the first time (primigravida). The goal of prenatal yoga is to prepare pregnant women physically, mentally and spiritually for childbirth. With careful preparation, the mother will be more confident and gain confidence in going through labor smoothly and comfortably. This study aims to determine the effectiveness of prenatal yoga on anxiety and physical complaints of second trimester pregnant women at PMB Wulan Mardikaningtyas Singopuran Kartasura Sukoharjo.

Environmental problems today are indeed the most common problems in the environment, namely pollution, unhygienic ways of managing food, low levels of clean and healthy living (PHBS) and lack of clean water and healthy latrines. The latrine is a place for human waste disposal but there are still many people who do not dispose of their waste properly. The behavior of defecating (BAB) in any place and tends not to use the latrine is one of the habits that individuals have as a result of imitating the behavior of the people around them. Based on data from the Central Statistics Agency (BPS) in Rokan Hulu Regency, 9.61% did not use defecation facilities. The purpose of this study was to determine the factors that influence the ownership of latrines in Bangun Purba Village, Bangun Purba District. The method used was descriptive analytic with cross sectional design. The sample in this study amounted to 60 people. The sampling technique used is simple random sampling. Analysis of the data used is univariate analysis which performs univariable analysis and also bivariate analysis which performs statistical tests using the chi-square test. The results showed that there was a relationship of knowledge to the use of latrines in Bangun Purba Village with a p value of 0.001, there was a relationship between education and the use of latrines in Bangun Purba Village with a p value of 0.004, and there was a relationship between the role of health workers on the ownership of latrines in Bangun Village. Ancient with p value = 0.003. The conclusion is that there is a significant relationship between knowledge, education, and the role of health workers on latrine ownership. Suggestions need for counseling about the importance of latrines that are useful for maintaining public health and the environment.
Mapping subregional types of population dynamics of Irkutsk region

In the article the results of research of specifics of digital mapping of spatial and temporal dynamics of the population in a sparsely populated region (on the example of Irkutsk region). The study area is mainly inhomogeneously populated, with a sparse network of settlements (mainly spatially contiguous). The exception is the south territory along the Trans-Siberian Railway. To identify subregional and local characteristics of distribution of the population, the famous dazimetric method of V.P. Semyonov-Tyan-Shansky was used (adjusted for the features of sparsely populated regions). The boundaries of the areal inhabited territory are defined by the method of spots with a buffer radius of 3 km from the borders of populated locality.

The overlapping spots, form a solidly populated space, from which depart linear-band elements of settlement, formed on the base of settlements dislocated along the paths of old communications (rivers and roads). The article presents a geoinformation methodology for collecting and processing available statistical data about population movement. In contrast to usual mapping, the calculation of general population dynamics, growth component and subsequent mapping were implemented not in municipal districts, urban and rural settlements, but within localities and settlement areas formed by them, ignoring official boundaries. The mapping allowed to identify patterns and detailing of the dynamics of the population considering the features of real distribution of the population in Irkutsk region. There is a discrepancy between the tendencies of demographic and economic development. The growth of resource complex comes at the expense of the northern periphery of the region, and the general direction of the population system development—growth of demographic potential around the regional center in conditions of depopulation of the periphery. The experience of mapping subregional types of population dynamics in Irkutsk region can be used in mapping similar regions.

Penyebaran coronavirus desease-19 (covid-19) beralih pada klaster keluarga, sehingga meningkatkan jumlah kasus covid-19 secara signifikan. Berdasarkan sifat virus corona yang menyerang sistem imun, salah satu upaya yang dilakukan berupa penerapan perilaku hidup bersih dan sehat (PHBS) pada tatanan rumah tangga. Di masa pandemi covid-19 ini, penerapan PHBS pada tatanan rumah tangga kurang terkontrol meskipun beberapa indikator PHBS tatanan rumah tangga telah terintegrasi ke dalam tindakan protokol kesehatan namun indikator lainnya belum terdeteksi. Tujuan penelitian untuk mengetahui penerapan perilaku hidup bersih dan sehat pada tatanan rumah tangga di masa pandemi covid-19. Rancangan penelitian berupa studi deskriptif dengan pendekatan survey. Responden berjumlah 197 kepala keluarga menggunakan rumus deskriptif kategorik dengan teknik accidental sampling. Hasil penelitian mayoritas keluarga telah melakukan seluruh indikator PHBS tatanan rumah tangga selama pandemi covid-19 meliputi, perilaku mencuci tangan dengan baik dan benar (76,1%), mengkonsumsi makanan sehat sesuai dengan gizi seimbang (53,8%), menggunakan jamban yang bersih dan sehat (75,6%), melakukan aktivitas fisik setiap hari (23,4%), membuang sampah pada tempatnya (67%), tidak merokok (51%), menjaga kebersihan lingkungan sekitar rumah (72,6%), menghindari dan mengelola stress dengan baik dalam kehidupan sehari-hari (51,8%), dan istirahat yang cukup (55,8%). Kedisiplinan keluarga dalam penerapan PHBS pada tatanan rumah tangga selama pandemi covid-19 perlu ditingkatkan terutama aktifitas fisik guna meningkatkan imunitas tubuh, sehingga membantu mencegah paparan covid-19 di lingkungan keluarga maupun masyarakat.

A importância da leitura na infância para a formação do sujeito leitor no contexto da realidade tecnológica digital

Este artigo aborda a importância da leitura na infância para a formação do jovem leitor, utilizando como ferramenta nesse processo as tecnologias digitais. Com a expansão da internet e o desenvolvimento de ferramentas e aplicativos, tem-se acesso a grande quantidade de textos e informações, o que pode permitir maior número de leituras. Mas isso não significa ler com mais qualidade, capacidade de análise e compreensão crítica. O Indicador de Alfabetismo Funcional (INAF) 2018 constatou que o brasileiro tem dificuldades para atingir o nível de proficiência em leitura e escrita. E o Programa Internacional de Avaliação de Estudantes (PISA) 2018 divulgou que o brasileiro tem baixa proficiência em leitura comparado com estudantes de outros países. Esse contexto levou à investigação de como o ensino e a aprendizagem de leitura na infância são importantes para a formação do jovem leitor, utilizando as tecnologias digitais como ferramentas nesse processo. Para tanto, foi realizada uma pesquisa bibliográfica, a partir da qual verificou-se que ler é uma atividade complexa de interação e produção de sentidos (SOLÉ, 1998; DELL’ISOLA, 2001; KOCH; ELIAS, 2006). E as estratégias que permitem a condução dessa prática precisam ser ensinadas, não sendo uma aquisição espontânea e individual. Assim, o cotidiano das crianças, inseridas ou não em processo escolar, precisa ser constituído por práticas de desenvolvimento dos multiletramentos, incluindo o digital (SOARES, 2002; RIBEIRO, 2006; XAVIER, 2011; COSCARELLI, 2017). Os nativos digitais apresentam certa facilidade com o uso de ferramentas tecnológicas, a partir das quais podem aperfeiçoar a leitura não apenas de signos linguísticos, mas também de recursos audiovisuais. Portanto, nos ambientes familiar e escolar, cabe o incentivo ao uso de programas, jogos e aplicativos de qualidade, com mediadores de leitura que conheçam e compreendam os recursos digitais, propiciando o uso construtivo por parte dos leitores em formação.
Interacción colaborativa en aplicación móvil: una propuesta de enseñanza híbrida en clases de español

Published: November 2021

Este artículo presenta una investigación cualitativa, también una observación participante y un estudio de caso, hecha con estudiantes de la Enseñanza Fundamental (EF) de una escuela pública Federal, de la región norte de la ciudad de Goiânia, en el Estado de Goiás, Brasil. En este estudio se propuso una actividad de interacción colaborativa en aplicación de mensajería móvil en las clases de Español Lengua Extranjera (ELE). La propuesta se justifica pues las clases de Lengua Extranjera (LE) ocupan muy poco el horario de clases con un máximo de una hora y media por semana. Este tipo de actividad que mezcla la enseñanza en clase y en contexto digital se encuadra en la perspectiva de la enseñanza híbrida y tiene como objetivo principal fomentar la autonomía y la colaboración entre los estudiantes en otros ambientes de enseñanza diferentes de la clase. Los supuestos teóricos utilizados en este estudio se basan en la teoría sociocultural de Vygotsky para explicar la interacción colaborativa y el andamiaje entre los alumnos y/o la profesora. También la teoría de la enseñanza en contexto híbrido y la utilización de aplicación móvil de mensajería como herramienta pedagógica. Se percibe en algunos estudios que la utilización de aplicaciones móviles es una tendencia entre los profesores de diversos niveles y que ha presentado muy buenos resultados para la enseñanza y aprendizaje de lenguas.
