Do ensino remoto emergencial ao HyFlex:
Authors: Schlemmer Eliane , Moreira José António Marques
Published: February 2022

O Ensino Remoto Emergencial, as Aulas Simultâneas e o Modelo HyFlex representam opções pedagógicas construídas durante a pandemia do COVID-19. Estas propostas situam-se ao nível da solução de problemas, cuja resolução emerge da atenção à vida pragmática, o que implica criatividade. Nesse movimento, um novo nível de atenção é necessário, uma atenção suplementar, o que contribui para a invenção de problemas e onde se potencia a Educação Híbrida e emerge a Educação OnLIFE. O objetivo  deste  artigo,  de  natureza  eminentemente  teórica, último da trilogia "Paradigma de Educação OnLIFE" é discutir as principais abordagens educacionais desenvolvidas em tempos de pandemia e a emersão de um paradigma educacional onde não exista distinção entre offline e online e onde as tecnologias digitais e as redes não sejam encaradas como ferramentas, mas como forças ambientais que afetam a nossa auto-conceção, as nossas interações e como ensinamos e aprendemos.

Published: February 2022

RESUMO: O artigo em revista é um recorte de uma pesquisa de pós-doutorado em curso e elege as narrativas digitais, as vídeo-cartas e as juventudes como categorias teóricas centrais. Intenta analisar as repercussões das vídeo-cartas produzidas por jovens no âmbito da educação. A escrita em tela inicialmente descreve quatro projetos de vídeo-cartas de jovens e discute suas formas de expressão, mediadas pela tecnologia. A trilha metodológica contou com uma revisão de literatura sobre narrativas digitais, vídeo-cartas e projetos de vídeo-cartas. Os resultados da revisão de literatura deste artigo revelam que a produção acadêmica sobre narrativas digitais e vídeo-cartas são recentes no Brasil, como os estudos Kieling (2012), Rodrigues (2020), Ruiz (2009) e Dultra (2018). Quanto aos projetos analisados, as vídeo-cartas mostraram que as narrativas digitais dos jovens, tomados aqui como sujeitos históricos e singulares (LEIRO, 2004), trazem reflexões subjetivas sobre suas vidas, concorrem para ressignificação das cartas tradicionais e indicam novos tempos no entrecruzamento da educação com as tecnologias contemporâneas.

Published: February 2022

Este artigo apresenta uma investigação sobre a relação entre inovação pedagógica e ensino remoto emergencial. Apresenta uma apuração sobre a transladação das aulas presenciais para o formato remoto, que aconteceu por causa da pandemia gerada pelo Covid-19. O estudo é de caráter qualitativo e exploratório, com aplicação de questionários aos professores que estão lecionando remotamente, sendo a amostra não probabilística. Em duas etapas distintas, usando a metodologia “bola de neve”, produzimos dados para análise. A primeira etapa teve como ênfase inovação pedagógica e a segunda foi direcionada para avaliação no ensino remoto emergencial. Os resultados mostram que a maior parte dos professores apenas transladou a sua metodologia para o formato online, ainda que a maioria tenha feito um replanejamento das suas aulas. Conclui-se que ainda é necessário aprofundar a relação entre tecnologias e inovação das práticas pedagógicas.

Published: February 2022

Salta es una de las provincias ubicadas en el NOA (Noroeste Argentino) que presenta mayores datos alarmantes de desigualdad en la región, en términos de desocupación, pobreza infantil, desnutrición y femicidios (Chachagua, 2019). La desigualdad socioeconómica pre existente fue profundizada en el contexto de pandemia originado por el COVID-19 desde principios de 2020, e impactó fuertemente en el ámbito educativo, tanto en el acceso (dispositivos tecnológicos y conectividad) como en los procesos de enseñanza- aprendizaje; por lo que las trayectorias educativas se vieron afectadas y modificadas, especialmente en los sectores más vulnerables. En este artículo se propone problematizar las desigualdades educativas y digitales en una escuela rural de la provincia de Salta, teniendo en cuenta el contexto general. Se abordará este caso desde una perspectiva metodológica cualitativa (RIST, 1977) ya que es inductiva y sigue un diseño de investigación flexible; para lo que entrevistó a varias trabajadoras de la institución para que dieran cuenta de la situación de transformación y desafíos educativos que tuvieron que enfrentar por la pandemia. Además, se tomaron algunos datos de la Encuesta Permanente de Hogares (EPH), la MAUTIC, y otros materiales relevantes para describir el contexto educativo y el acceso a las TIC en Salta.

El Tiempo de la Araña
Authors: Sierra Franco Angélica María , Monterroza Jesús
Published: February 2022

Los poetas Angélica María Sierra Franco (textos) y Jesús Monterroza (ilustraciones) han decidido, felizmente, co-crear el hermoso libro de poesía El Tiempo de la Araña. Ya desde el mismo hecho de la doble autoría, este poemario resulta interesantísimo, por haber sido “escrito” desde una visión bifronte, en la que se conjugan lo femenino y lo masculino, síntesis expresiva que potencia el hecho poético. Angélica María Sierra Franco y Jesús Monterroza en El Tiempo de la Araña han activado el tejido de su propia realidad y, a través de él, se aproximan a la comprensión del mundo como ser, del ser en el mundo y de la existencia de ambos como un todo creado y creador. El Tiempo de la Araña es un libro absolutamente sustentado en la realidad simbólica, compuesto por un bestiario ejemplificante con el que los creadores tejen sus aspiraciones, deseos y pensamientos. La abeja, la hormiga, la almeja, el pájaro, el comején, el búfalo, el caballo, el tiburón, el mosquito son las fuerzas poéticamente simbolizadas que activan el sentido textual que, en unidad temática y estilística, abarca todo el libro. A través de ese bestiario se aprecia y comprende el mundo, al poner por delante un ansia de trascendencia que se vuelve genésica siempre y que otorga a cada poema un rigor depurado y una visión consolidada y valiosa, creada, verso a verso, con el misterio de las cosas que ofrece la naturaleza en su estado más originario y virginal.

Since its molecular isolation on January 7, 2020, the new SARS-CoV-2 coronavirus has spread rapidly, affecting regions such as Latin America. Ecuador received the worst outbreak globally if we count excess mortality per capita. This study describes the clinical, epidemiological and therapeutic characteristics of 89 patients admitted to an intensive care unit (ICU) in a second-level hospital in Quito, Ecuador. Methods: We conducted a retrospective cohort study. We collected data from health records of adult patients with severe COVID-19 admitted to an ICU in Quito, Ecuador, during the first five months of the SARS-CoV-2 outbreak. We used the Chi-square test or Fisher's exact statistics to analyze risk and associations between survivors and non-survivors. We used ROC curve analysis to predict mortality and determine cut-off points for mechanical, analytical, and cytometric ventilation parameters. We used the Wald test to evaluate the categorical predictors of the model at the multivariate level during the regression analysis. Results: 89 patients were recruited. The mean age of the patients was 54.72 years. Men represented 68.54% (n=61) and women 31.46% (n=28). Significant differences in mortality were observed (men 40.98% vs. women 17.76%). LDH and IL-6 at 24 hours after hospital admission were higher among non-survivors than survivors. Persistent hypercapnia (PaCO2 >45 mmHg), a PaFiO2 ratio of less than 140 mmHg, and positive end-expiratory pressure (PEEP) titration >9 mmHg were also associated with increased mortality. Conclusions: Elevated levels of LDH at 24 hours, IL-6 at 24 hours, lymphocyte and platelet count at 48 hours, neutrophil count at 48 hours and NLR are factors associated with higher motility, higher risk of failed extubation and reintubation in patients with acute respiratory distress syndrome due to COVID-19.

Optimization of cephalosporin C acylase immobilization using crosslinked enzyme aggregates technique
Authors: Julkipli Julkipli , Syamsu Khaswar , Wibisana Ahmad
Published: February 2022

Cephalosporin C acylase (CCA) is an essential enzyme for the one-step conversion of cephalosporin C into 7-aminocephalosporanic acid (7-ACA), an intermediate compound used to synthesize various semi-synthetic cephalosporin antibiotics. The industrial process prefers to use enzymes in immobilized form rather than soluble. A crosslinked enzyme aggregate (CLEAs) is a potential matrix-less enzyme immobilization technique to produce stable immobilized enzymes with high activity and low production costs. This study aimed to optimize the CCA immobilization using the CLEAs technique with Chitosan as a co-aggregate. The CCA lysate was obtained from harvesting CCA fermentation broth using a mutant strain of Escherichia coli through cell separation and lysis steps. Partially purified CCA by ammonium sulfate addition was conducted to obtain an active fraction of 20-60% saturation, followed by co-aggregation with Chitosan to form physical CCA aggregates. The aggregates were then immobilized by a crosslinking technique using glutaraldehyde to form CLEAs-CCA. Optimization of the immobilization process was carried out by Response Surface Methodology in three steps, (i) screening of the influencing factors, (ii) determining the level of the significant factors, and (iii) optimizing the immobilization condition. The CLEAs-CCA activity was used as a response parameter. Under optimum conditions, CLEAs-CCA activity obtained was 85.91 Ug-1.

Published: February 2022

Background

As evidenced by the further reduction in access to testing during the COVID-19 pandemic, there is an urgent, growing need for remote cognitive assessment for individuals with cognitive impairment. The Neurotrack Cognitive Battery (NCB), our response to this need, was evaluated for its temporal reliability and stability as part of ongoing validation testing.

Objective

The aim of this study is to assess the temporal reliability of the NCB tests (5 total) across a 1-week period and to determine the temporal stability of these measures across 3 consecutive administrations in a single day.

Methods

For test-retest reliability, a range of 29-66 cognitively healthy participants (ages 18-68 years) completed each cognitive assessment twice, 1 week apart. In a separate study, temporal stability was assessed using data collected from 31 different cognitively healthy participants at 3 consecutive timepoints in a single day.

Results

Correlations for the assessments were between 0.72 and 0.83, exceeding the standard acceptable threshold of 0.70 for temporal reliability. Intraclass correlations ranged from 0.60 to 0.84, indicating moderate to good temporal stability.

Conclusions

These results highlight the NCB as a brief, easy-to-administer, and reliable assessment for remote cognitive testing. Additional validation research is underway to determine the full magnitude of the clinical utility of the NCB.

Published: February 2022

This field research using participant observation critically analyzed the post-war reconciliation between Aceh Province and the Indonesian Government. Special attention was paid to the violent incidents at Rumoh Geudong, Krueng Arakundoe, and Jambo Keupok. Besides, in-depth interviews with 16 informants who were engaged directly and indirectly on the problems to collect the data, followed by employing library research to sight the findings. The peace agreement was concluded by parties who hated each other. Contrarily, the government’s function as the developer of the post-understanding process was not shown substantially. This has further enhanced the new forms of violence carried out after the previous violence. This meant nothing to the power of peace itself. The reconciliation was not substantially successful but failed. The absence of which had an impact on the existence of war victims, particularly in rebuilding their psychological conditions. Human values during the 14 years of peace were not programmed in priority at all, which generated extensive sustainable peace. The collapse of the state’s responsibility to unravel all cases of dehumanization had an impact on the increasingly dominating pragmatic value, meaning that the value of the existence of war victims was minimal, even closer to nothing.

Authors: Irsyad Muhamad Faqih
Published: February 2022

The Keyword Method (KWM) is a mnemonic method designed to assist learners in learning foreign vocabulary. The method encompasses two processes, namely, the similarity of the words in sound(s) or the similarity of the keyword spoken with foreign language words and created mental images. This case study of the intervention involved a 26 years old student who had newly commenced as a first-year Indonesian studies student at Flinders University, Adelaide. She is a locally born Australian student who speaks English as her native language. To interpret the result findings, the checklist method (consisting of correct, doubt, and no responses), descriptive analysis, and interviews, as well as observations, have been applied in the KWM implementation. The results proved that the KWM has successfully assisted the learner in improving her Bahasa Indonesia, both in acquisition and retention, in a more effective manner compared to her other study strategies. This was especially apparent after conducting the immediate and delayed comprehensive test. The subject was also able to generate self-regulated learning. This indicated that the subject is able to metacognitively, motivationally and behaviorally utilize her cognitive sources to control the tasks. Cognitive and metacognitive processes of the KWM implementation, involving the detailed information processing of the learner, are discussed here.

Published: February 2022

For ensuring of the efficient operation of tractors in agriculture, there is a need of the information on failures of aggregates and systems. In the agricultural production of Russia, serial tractors are operated in various production and climatic conditions, the specifics of failures in specific regions are of particular interest. Kirovets tractors are the most common in the agro- industrial complex of the Novosibirsk region. (Research purpose) The research purpose is to collect and analyze statistical data on failures of Kirovets tractors operated in agricultural production in the Novosibirsk region. (Materials and methods) Failures of Kirovets tractors were logged at the place of appearance and operating time of the tractor for three years. The sample consists of 129 tractors. The data obtained were processed by mathematical statistics methods. (Results and discussion) Forty one percent of failures occur in the operating time interval of up to 500 moto-hours. The maximum number of failures accounted for the chassis, 37 percent, and transmission units, 32 percent. Forty six percent of failures are caused by violation of operating rules, 8 by climatic factors, 46 percent by insufficient quality of the tractor itself. (Conclusions) The article describes a certain specificity of failures of the studied tractors in the conditions of the Novosibirsk region. The main reason for failures is the low quality of assembly and the use of substandard materials in production. The article recommends for improving of the reliability of the Kirovets tractor to develop proposals to adjust the frequency and content of maintenance, taking into account regional specifics. The manufacturer needs to pay more attention to the quality control of the assemblies and components and the incoming quality control of materials used in the production of the tractor.
A NEW METHOD FOR DETERMINING THE PERMISSIBLE WEAR OF PARTS, CONNECTIONS, MACHINE CONDITION PARAMETERS
Authors:   Federal Scientific Agroengineering Center VIM
Published: February 2022

The technical documentation contains a standard for permissible wear of machine parts. An indicator of the technical condition is a resource parameter that depends on the operating time or operating time of the selected part or node. (Research purpose) The research purpose is in developing a new methodology for determining the permissible wear of machine parts. (Materials and methods). When developing the method at the first stage, they tried to solve this problem economically, reducing the calculated costs of downtime, while optimizing the allowable wear. For the parts of the same name, the result gave large calculation errors, since they did not take into account the influence of different wear rates on reliability indicators, the probability of failure and service life. With an increase in the rate of wear, the probability of failure turns into the probability of preventive replacement. In order to increase the reliability of the results of the study, it is necessary to take into account the climatic conditions of operation. Since the standard is constant for all regions of the country, it is necessary to change its value for different regions. (Results and discussion). The article presents the dependence of the increase in operating time on the wear rate of a group of the same name; the lower the wear rate, the greater the operating time of such parts. The probability of failure also changes by changing the resource of these parts. (Conclusions). This technique makes it possible to reduce the probability of failure by five or more times during the inter-control period. This circumstance can make the diagnosed machine trouble-free, provided it is equipped with modern means of monitoring the technical condition.

Published: February 2022

The current trend in the development of scientific and technological progress is characterized by the development and production of a huge number of automated agricultural machinery. Thorough knowledge and understanding of the content and essence of automated agricultural machinery makes it possible to operate it professionally and effectively. (Research purpose) The research purpose is in creating recommendations on identifying the causes of failures and malfunctions, as well as on the effective operation of automated agricultural machinery. (Materials and methods) The automation system is designed in the form of an expanded block diagram, and its elements are represented by conventional symbols, which are divided into graphic and alphabetic designations. The structural diagrams show the mechanisms of formation of control signals, commands and actions in automation systems; control circuits, regulation, control and signaling; automatic control regulators, monitoring and signaling. (Results and discussion) During the structural analysis it is necessary to determine the full composition of structural elements in each automation system under study. When performing a detailed structural analysis, you need to use the results of a simplified one, and consider the automation object with all its input and output physical parameters. The automatic regulators of the system must be subjected to additional structural analysis. (Conclusions) Detailed structural analysis is the most popular direction and fully reveals the structure of automation systems. The use of detailed structural analysis leads to an understanding of the essence of automatic control of objects in some types of automation systems and the essence of automatic control of the state of objects in other types of automation systems. Performing a detailed structural analysis sufficiently fully reveals the descriptive and cognitive nature of the process of studying automation systems.
«Smart City» in Socio-Political Projection (The Case of Barcelona)
Authors: Baranov A. V. , Garas L. N.
Published: February 2022

This article reveals the process of becoming a “smart city” based on the materials of Barcelona. The socio-political aspects of the use of “smart city” technologies in the information and communication era are revealed.The authors use of the system method made it possible to study the technologies of the “smart city” in aggregate, and the use of the comparative method made it possible to establish the specifics of the development of Barcelona during the tenure of Mayor Xavier Trias and Ada Colau. The authors draw attention to the reasons for the recognition of the capital of Catalonia as the most high-tech city in the world in 2015. It is emphasized that Barcelona has made a rapid breakthrough in a relatively short period of time, turning into a post-industrial city. It is noted that the driver of Barcelona’s transformation was the holding of the XXV Summer Olympic Games in 1992, which essentially changed the appearance of the city.The authors point to the additional opportunities in city management that the information and communication revolution led to and the speed of the Internet penetration rate. It is emphasized that information and communication technologies led to the transformation of a rigidly vertical bureaucratic system of exercising power and set the vector of its transition to a horizontal (network model) based on the effects of high technologies.It is noted that the modern model of exercising power in Barcelona presupposes the active involvement of citizens in the processes of city management, based on the use of technological platforms that simplify coworking processes.As a result of the study, the authors come to the conclusion that the contemporary paradigm of the “smart city” involves the involvement of citizens as active participants in decisionmaking and planning. Attention is focused on the formation of two models of urban governance in Barcelona, differing in the dynamics of the exercise of power and the prevalence of tendencies from “top to bottom” (mayors of the city of K. Trias) and from “bottom to top” (mayor of the city A. Colau). The authors emphasize that modern Barcelona is not only a flagship of technological development, but also a city with democratic traditions and a high level of humancentered orientation.

Published: February 2022

Pencemaran udara yang meningkat sekarang ini mengakibatkan beberapa permasalahan kesehatan bagi masyarakat luas. Bertambahnya jumlah kendaraan bermotor, industri tidak ramah lingkungan dan juga penggunaan energi pembangkit listrik yang tak terbaharukan menjadi penyebab utama permasalahan ini. Karbon dioksida menjadi salah satu komponen dalam pencemaran udara yang apabila terpapar manusia dalam kadar yang tinggi dapat mengakibatkan kehilangan kesadaran hingga akibat paling buruknya adalah kematian. Salah satu faktor yang memperburuk pencemaran udara adalah kelembaban udara. Kelembaban udara berbanding lurus terhadap konsentrasi CO artinya ketika kelembaban meningkat maka konsentrasi CO juga meningkat. Quadcopter atau drone merupakan suatu pesawat tanpa awak yang memiliki empat lengan dengan masing-masing satu motor sebagai pemutar baling-baling. Dengan mengaplikasikan quadcopter yang bergerak secara manual ataupun otomatis melalui titik waypoint yang sudah ditentukan ditambah dengan arduino sebagai modul mikrokontroler yang dilengkapi dengan sensor gas MQ-7 untuk mendeteksi gas CO dan sensor DHT-22 untuk mendeteksi kelembaban udara. Hasilnya adalah kadar ppm gas CO yang dipantau pada sore hari pada ketinggian 10 meter memiliki rata-rata kadar sebesar 3,31 ppm, pada ketinggian 15 meter memiliki rata-rata kadar sebesar 3,36 ppm, dan pada ketinggian 20 meter memiliki rata-rata kadar sebesar 3,40 ppm

Kemajuan teknologi dalam bidang robotika pada saat ini sudah memasuki era modernisasi serta perkembangannya memasuki era baru dan sudah serba otomatis untuk sebuah pendidikan dan teknologi. Robot lengan pada dunia industri berpengaruh sangat besar, misalnya dapat membuat waktu lebih efisien dan dapat mengurangi biaya dimana yang sebelumnya harus membayar gaji karyawan. Berdasarkan hasil pengujian sinkronasi gerak antar robot lengan dan slider pengendali didapatkan hasil bahwa semakin besar nilai derajat pergesaran slider maka lebar pulsa sinyal PWM semakin melebar dan tegangan keluaran dari pin mikrokontroler Arduino Uno semakin besar dengan nilai rata – rata tegangan yang dihasilkan sebesar 115,03 mV. Robot dalam keadaan standby hanya membutuhkan daya sebesar 0,9 Watt dan saat beroperasi membutuhkan data sebesar 3,94 Watt. Pada motor servo ini, terdapat beberapa kekurangan, dimana salah satunya adalah tidak akuratnya dalam melakukan pengukuran sudut, dapat dihitung bahwa selisihnya sebesar 13% atau sejauh 7,3 derajat.
