Published: August 2021

The issue of psychological feasibility of distance learning is understudied and remains relevant both in theoretical and practical terms. The purpose of the study viewed in the article is to identify the connection between students’ preferences to study using the Internet and electronic textbooks with their personal psychological traits. Presumably, confident, self-organized students have a positive attitude towards their use, while anxious, emotionally unstable students have a negative attitude. The study involves 1st – 4th year students (N = 270, aged from 17 to 21 years; 61.3% women) students, who specialize in Economics and Agricultural Industry in Izhevsk State Agricultural Academy. We used the following techniques: questionnaire developed by O. N. Malakhova, O. A. Zhuchenko, aimed at studying students’ preferences and Cattell’s Personality Factor Questionnaire (16-PF), form C, which has the goal to study personality traits that are significant for the research. It was found that there was a direct interconnection between students’ preference to use digital educational resources with their personal psychological traits. The study revealed that students with self-discipline and analytical mindset have a negative attitude to the use of electronic textbooks and distance learning. It was found that among the main personal psychological characteristics of students, which influence their preferences, are sensitivity and radicalism, anxiety and lack of self-discipline. We did not confirm the hypothesis put forward in the study. The applied aspect of the problem under study can be implemented in educational practice to increase the efficiency of educational process and in the development of digital training courses. The research perspectives are related to the study of teacher preferences.

Authors:   Saratov State University, Kosareva Svetlana A.
Published: August 2021

The article presents theoretical analysis of the phenomenon of self-organization and its definition and introduces the structural-functional model of pedagogical support for increasing the level of students’ self-organization. It was developed due to the fact that students have well-developed skills of self-organization, since they need to cope with a large amount of autonomous work, and university graduates, since they are required to solve professional problems effectively. The purpose of the study is justification of the content of the model blocks. The hypothesis of the study is that the implementation of the model will provide an increase in the level of students’ self-organization. The model includes the purpose, approaches, principles of teaching, pedagogical conditions, description of teacher and students’ activities, methods, forms and means used in the educational process. The model has criteria, indicators and levels of self-organization as well. The author provides justification for the application of these approaches and principles of teaching, explains the need to create certain pedagogical conditions. Work on increasing the level of students’ self-organization consists of a theoretical and practical part, which correspond to the preparatory and main stages of pedagogical support. Thus, the practical part of the work includes students’ project activities aimed at compiling a textbook, which serves as a basis for training self-organization skills. The control and correction stage is connected with determining the achieved level of self-organization on the basis of its criteria and their indicators. We highlighted and gave a description of three levels of self-organization. The result of the analysis is that students’ level of self-organization becomes higher.

Published: August 2021

The relevant problem of social educational psychology is to identify states of self-organization and self-development of students’ psychological traits in the academic group. One of the possible ways to solve the problem is to use the mathematical theory of dynamic systems to determine the attractors of the development stages of university students’ agency. The purpose of the study presented in the article is to substantiate application of the theory of complex dynamic systems in modeling development stages of university students’ agency. Hypothesis of the study: the theory of complex dynamic systems is applicable to modeling the development stages of university students’ agency. Approbation of the theory of dynamical systems was carried out in the course of a longitudinal study in four groups of 1st to 4th year full-time students (N = 79; M = 19.6; SD = 2.4 years; 100% women). The study revealed that the development stages of university students’ agency have one stable stationary state. The interval between two measurements was 28 weeks. The most common attractors are found in the “learner” and “master” stages. We revealed two stable states in the stages in the second-year students’ group. The stages indicate presence of micro groups with different levels of manifestation of development stages of agency, which are characterized by the phenomenon of self-organization in the academic group. The applied aspect of the study is to create a dynamic model of the stages of university students’ agency development in a separate academic group. The research showed prospects of applying the dynamic systems theory combined with the ecopsychological approach.

Published: August 2021

Introduction: One of the simplest methods to predict mesiodistal width of permanent canines and premolars is using Tanaka and Johnston’s prediction formula; however, dental size varies according to race. The study aimed to examine the relationship between incisors mesiodistal width and mandibular first molar’s with mesiodistal width of maxillary and mandibular canines and premolars and to determine the reliability of Tanaka and Johnston prediction formula.
Materials & Methods: In the present cross-sectional study, 200 pairs of a dental cast of 12-25 years old were selected and the greatest mesiodistal width of canines and premolars crown in each jaw and incisors and mandibular first molars were measured with a digital caliper with 0.01 resolution. Data were analyzed using regression analysis, t-test (p value < 0.05).
Results: There was a significant statistical difference between actual width and Tanaka and Johnston prediction formula in the group under study (p value < 0.001). Moreover, a new linear equation for the prediction of mesiodistal width of maxillary and mandibular canines and premolars based on mesiodistal width of lower incisors and mandibular first molars was developed using regression analysis.
Conclusion: In statistical terms, Tanaka and Johnston’s prediction formula is not applicable for the population under study because maxillary estimated measures were a little high and mandibular estimated measures were a little low.

Zastosowanie analizy planimetrycznej w badaniach geologicznych – eksperymenty i spostrzeżenia
Authors:   Instytut Nafty i Gazu – Państwowy Instytut Badawczy, Ziemianin Konrad
Published: August 2021

Planimetric analysis is a well-known and commonly used method for determining the content of a given component in the area of the analyzed surface. In geology, it is used to determine both the mineral and maceral composition, and its results are helpful in solving a wide range of research problems. The aim of this study was to investigate the relationships between the obtained results of planimetric analysis and the density of the measurement grids, which can be adapted to specific situations in geological samples in order to optimize the ratio of the accuracy of the result to the time of analysis. The research was divided into two stages. Models were used in the first stage, while in the second, coal samples were investigated. In the first stage, a virtual grid of measurement points with dimensions of 100 by 100 points was created, which gave a total of 10 000 points. After creating the measurement grid model, 102 scenarios were established, differing in the content of the analyzed component A (0.1%, 0.5% and from 1 to 100%). In each of the adopted scenarios, 100 combinations were carried out so that the arrangement of points on the measurement grid corresponding to component A was random. Then, the number of measuring points was reduced several times from the original 10 000 to 100 and each time content of component A was calculated. The obtained average component A content in most cases turned out to be only slightly different from the original, which cannot be stated in the case of both minimum and maximum values – here a wider range of results is observed. In the second stage, 3 coal samples of varying maceral composition complexity were investigated and a measurement grid of 100 by 100 points was used. The original grid density was gradually reduced (down to 144 points) and maceral composition was calculated each time. Results obtained from models as well as from samples show a clear trend of decreasing accuracy with decreasing density of the measuring grid. The obtained results were also analyzed in terms of the established acceptance criteria for which the content of the component was assumed to be different from its content based on a grid of 10 000 points by up to 5%, 10% or 30% of the original value. The analysis of the relationship between the accuracy of the obtained results and the time of conducting the analysis seems to indicate that the choice of the measurement grid based on 500 points is optimal.

Artykuł omawia badania laboratoryjne ukierunkowane na stwierdzenie, w jakim zakresie możliwa jest neutralizacja siarkowodoru przez bakterie z rodzajów Thiobacillus i Acidithiobacillus w środowisku wody złożowej i wody technologicznej. Woda złożowa pochodziła z obszarów PMG (podziemnego magazynowania gazu) oraz z obecnie eksploatowanych złóż; wody pobierano głównie ze złóż gazu ziemnego. W trakcie eksperymentów zastosowano zróżnicowany czas inkubacji próbek testowych: od inkubacji 1-dobowej do 30-dobowej. W poszczególnych próbkach określano zmiany zawartości H2S pod wpływem oddziaływania kultur bakteryjnych w stosunku do zawartości siarkowodoru w próbkach kontrolnych. Obliczono procentową zmianę poziomu H2S w badanych próbkach wód złożowych. Kolejne testy przeprowadzono na skażonych wodach technologicznych. Są to tzw. wody bazowe, służące do sporządzania wodno-dyspersyjnych polimerowych płuczek wiertniczych. W wodach tych również badano zmiany zawartości siarkowodoru pod wpływem działania bakterii. W ramach pracy dokonano porównania działania czterech zawiesin bakterii z rodzajów Thiobacillus i Acidithiobacillus. Zdecydowanie najbardziej efektywne okazały się bakterie A. thiooxidans, natomiast na drugim miejscu była zawiesina A. ferrooxidans. Szczegółowe wyniki zawarto w zestawieniach tabelarycznych. Pozostałe zawiesiny bakterii z rodzaju Thiobacillus użyte w pracy badawczej okazały się znacznie mniej skuteczne w neutralizacji siarkowodoru w badanych próbkach wód. Artykuł omawia również wyniki przeprowadzonych testów obrazujących łączny efekt oddziaływania bakterii oraz inhibitora azotanowego (o nazwie BMF Bac 4), stosowanego w niektórych złożach w ramach technologii nitrate-based treatment. Technologia ta znalazła zastosowanie na świecie jako alternatywa dla wykorzystania biocydów, w celu zmniejszenia zawartości siarkowodoru w mediach złożowych.

The article presents the results of research on the possibility of increasing the recovery factor of oil fields by implementing the waterflooding treatment as one of the most common enhanced oil recovery method. Based on the interpretation of data from the core flow tests, an attempt was made to characterize the displacement process using original reservoir brine and waters with lower salinity level. Additionally, the relation between the type of wettability of the rock and recovery factor was investigated. Original reservoir fluids that were characterized in terms of their basic rheological parameters were used for research purposes. The rock material consisted of 16 samples of Cambrian sandstones. The initial scope of work concerned the petrophysical characteristics of the cores, including the determination of their basic parameters, such as absolute gas permeability, porosity and pore volume. Based on the determined values of permeability, the available samples were grouped which made it possible to perform test sets for pairs with the most similar filtration parameters in the next stages of the research. Further work included the performance of relative permeability analyses and the determination of the value of the mobility factor for the oil – reservoir water system in order to determine the type of wettability of the rock and the potential efficiency of the oil displacement process. The main element of the research was the simulation of the waterflooding process carried out in two parts – the first with the use of the original reservoir water (corresponding to the secondary recovery methods) and the second with the use of low-salinity waters (the third recovery methods) in two variants of the mineralization level. Based on the obtained data of the displaced oil, for each of the displacement medium recovery factor curve were constructed and compared with the determined type of wettability of the rock.

Authors: Mele Arellano Graziela
Published: August 2021

La crisis por la COVID-19 ha generado consecuencias en diversos aspectos de la vida social en el que destaca, entre ellos, la esfera económica. Los cambios dentro de la economía mundial fueron ocurriendo uno tras otro. Los mercados se volvieron más impredecibles, los modelos utilizados fueron reestructurados y las empresas se reinventaron. Los negocios pequeños y con crecimiento a corto plazo fueron cada día más comunes de encontrar y, en una cierta cantidad de casos, los emprendedores nos han mostrado que salirse del status quo es necesario para encontrar el “éxito”. Los emprendimientos, hoy en día, protagonizan un boom que vale la pena documentar. La Antropología empresarial tiene mucho por registrar, analizar y aplicar dentro de un futuro cercano acerca de los emprendimientos y empresas con rápido crecimiento como los startups. El presente texto es una crónica de campo basada en la labor antropológica dentro de un pequeño startup durante el periodo marzo-agosto del 2020. Se basa en la primera experiencia laboral que tuve y que, coincidentemente, fue ejecutada paralelamente a una crisis sanitaria mundial. De esta forma el objetivo general del texto es contar las experiencias del trabajo desde mi perspectiva antropológica dentro de una empresa. La crónica narrada a continuación recoge fragmentos de entrevistas realizadas, reflexiones y análisis del posicionamiento de la empresa “Mamá al rescate”.
Los procesos de juridificación de la ronda campesina de Macusani
Authors: Arredondo Villar Claudia
Published: August 2021

El presente artículo explora los procesos de juridificación en las rondas campesinas del distrito de Macusani en la región de Puno, un escenario de pluralismo jurídico presente en los márgenes del Estado. Para ello, se analiza la presencia de elementos del Estado en las prácticas y discursos de los ronderos y ronderas; particularmente, el lenguaje jurídico adoptado por la ronda y lo que ello implica para la construcción de la legitimidad y autoridad de esta organización campesina. Se emplea una metodología cualitativa de corte etnográfico para analizar un caso observado en una asamblea extraordinaria de la ronda de Macusani, en el cual se identifican varios momentos donde se invocan estratégicamente instrumentos legales, que reflejan la adopción y apropiación de discursos y procedimientos para-legales. Entre ellos, se encuentran el Convenio internacional Nº169 de la Organización Internacional del Trabajo, la Ley de Rondas Campesinas Nº 27908, el discurso de Derechos Humanos, y otras normativas del Estado empleadas en los argumentos de los ronderos y su concepción de la justicia.

Authors: Dash Bhabani Shankar , Swain Sangram Keshari , Behera Debaraj , Rayaguru Kalpana , Meshram Megha
Published: August 2021

Background: Green gram is a popular pulse crop in India (with 2.02 MT production over a cultivated area of 4.26 Mha) and Odisha (20.8 lakh ha area with a yield of 10.60 lakh tonnes). The information on the engineering properties and its behavioural changes with moisture content is vital for handling and designing of different agricultural processing equipment. Methods: This work mainly focused on studying green gram variety’s (Sujata) engineering properties at five different moisture levels (within a moisture range of 10.58 to 45.45% (d.b.). Standard methods and procedures were followed in the study and the output results were compared with previous research work to justify the variation or anomaly in some cases. The curve estimation method (regression analysis) was followed to find the best-fit curve and equation for the parameters studied. Result: The geometric mean diameter (GMD) of grain increased from 3.75 to 4.12 mm within the moisture content (MC) range and the variation was statistically significant (p less than 0.05). Sphericity and surface area varied significantly from 0.83 to 0.82 and 44.13 to 53.45 mm2, respectively, within the range of moisture contents studied with a high correlation among the data. Mass of thousand grains augmented (44.13 to 53.45 g) with a rise in MC and the data followed logarithmic and inverse curves. Bulk and true densities of green gram declined significantly from 860 to 670 kg m-3 and 1330 to 1240 kg m-3 with an increase in the moisture content. The porosity of green gram increased significantly from 35.75% to 46.38% and the terminal velocity raised from 9.20 m s-1 to 11.10 m s-1 with an increase in MC. The dynamic angle of repose increased significantly from 30.95 to 46.57o with MC. A significant variation in the coefficient of internal friction (0.78 to 0.90) was observed for the grains. The coefficient of static friction of grain increased significantly for different surfaces (MS, SS, Plywood and GI) with a rise in MC. The MS surface produced the highest coefficient of static friction and SS had the least. The results confirmed significant effect of MC on all engineering properties of green gram.

Background: The aim is to study the pharmacokinetics and tissue residue status of tilmicosin after administration through ‘in-crop’ and ‘in-water’ routes and compare the effectiveness of the two routes and establish a suitable dosage regimen for treating Mycoplasma gallisepticum infection in broiler chicken. Methods: The plasma pharmacokinetic disposition of tilmicosin in broiler chicken was investigated after administration orally by direct deposition at crop (25 mg/kg body weight) or drinking water (40 mg/kg b.wt.). Residues of tilmicosin in tissues of broiler chicken were assayed. The plasma and tissue concentrations of tilmicosin were analyzed by reverse-phase high-performance liquid chromatography (HPLC) method. The plasma concentration-time data was described by the non-compartmental model for both routes and pharmacokinetic parameters were calculated. The data were statistically analyzed by Mann-Whitney U test. Conclusion: The mean plasma concentrations of tilmicosin in two routes tested (in-crop, in-water) were effective above MIC reported for Mycoplasma gallisepticum (0.05 µg/ml) up to 24 h. In addition, the drug residue in lungs was found at desirable concentration up to 22 days. However, residues of tilmicosin in tissues were above the advocated maximum residue limit (MRL) till 18th day in muscle and liver and till 22nd day in kidney. The results of the study indicate that the antimycoplasmal drug tilmicosin can be therapeutically efficacious after administration in crop as well as in drinking water.

Background: Elasmobranch is one of the largest marine fish resources, consisting of sharks, sawfishes, rays and skates. A worldwide estimate of elasmobranch diversity reveals 815 species coming under 9 orders, 42 families and 164 genera, of which 359 species are sharks and 456 are skates and rays. Hence, it has been planned to investigate the biodiversity and fishery of elasmobranchs along the Coromandel Coast of Tamil Nadu, Southeast India. Methods: Elasmobranch specimens were collected during June 2019 to March 2020 from three main landing centres of Coromandel Coast of Tamil Nadu viz Royapuram (Chennai), Cuddalore and Nagapattinam Fishing Harbours. Sampling was done fortnightly in the above three landing centres. The specimens were collected from the catches of trawl nets, bottom set gillnets and hook and lines. The specimens were identified morphologically in the landing centres itself based on the valid taxonomic keys. Result: In the present study, 67 species of elasmobranch belonging to 7 orders, 21 families and 46 genera were recorded. Of the 7 orders, Carcharhiniformes had the largest number of species (27). Among the 25 families, Carcharhinidae (21) had the largest representation.
​Influence of Pre-sowing Treatments, Sowing Positions and Age of Stones after Extraction from Fruit on Germination and Vigour of Mango
Authors: Reshma U.R. , Simi S.
Published: August 2021

Background: Mango stones are in general recalcitrant. Moreover, they are available only during April- May months which are the drier parts of the year. So stone germination and plant vigour are very low. Proper seed orientation, age of stones after extraction from fruit and pre-sowing treatments need to be taken into consideration for inducing early germination, boosting growth, enhancing the seedling vigour and reducing the mortality. Methods: The experiment was laid out in factorial completely randomized design with forty two treatment combinations replicated thrice. The treatments were comprised of two sowing positions viz., flat and stalk end up, three age of stones after extraction from fruit, viz., fresh extracted, 10 days and 20 days after extraction and seven pre-sowing treatments viz., 100 ppm GA3, 200 ppm GA3, 1 ppm KNO3, 2 ppm KNO3, cow dung slurry, water, control and their combinations. Result: Stalk end up sowing of freshly extracted stones pre-treated with 200 ppm GA3 for 24 hours recorded better germination and vigour of mango seedlings.

In today’s labour market, being competitive requires, in addition to technical skills, several twenty-first-century career competencies, including the capacity to think critically. Although the literature on teaching methods designed for enhancing students’ reflective thinking abounds, the contribution of special tasks with varying complexity to learners’ critical thinking capacity, to our knowledge, has not been earlier investigated. Hence, the present investigation sought to investigate the effect of multi-level critical thinking activities introduced into classes on the critical thinking level of post-secondary vocational students. This cross-sectional study employed the Starkey Critical Thinking Test adapted for the Russian-speaking population in order to measure critical thinking level in a sample (n = 218) of vocational students. Results showed that among students whose classes were complemented by critical thinking tasks, almost half of subjects with low and test scores eventually shifted to a medium scoring cohort. Eleven learners who were medium scorers at the beginning gained high-level results at the end point. Meanwhile, only a small percentage of those no-treatment participants with initially low performance on the critical thinking test eventually moved into the medium level, as well as from the latter into a high achievement category. The independent two-tailed t-test revealed a significant difference between posttest scores observed in control and intervention groups. It can be therefore suggested that critical analysis of thought-provoking materials with subsequent class presentation and discussion can provide catalytic conditions for developing learners’ reflective thinking abilities. It was recommended that future studies using similar intervention should involve a larger sample and deal with qualitative data to extend the research and increase its validity.

Se presentan los resultados preliminares del proyecto Movilización del concepto ambiente en estudiantes de grado sexto, específicamente los resultados de la exploración conceptual sobre ambiente. El proyecto tiene como objetivo el diseño y construcción de una propuesta pedagógica y didáctica que contribuya a la movilización de las concepciones de ambiente instaladas en estudiantes hacia una visión sistémica del mismo y que sea pertinente con las intencionalidades formativas del Proyecto Ambiental Escolar (PRAE). El proyecto se lleva a cabo bajo el paradigma Socio crítico, con enfoque investigativo Cualitativo y una metodología Investigación acción, con una muestra de 29 estudiantes con edades entre 11 y 13 años pertenecientes a uno de los tres grados sexto de la Institución Educativa Técnica Enrique Olaya Herrera del Municipio de Guateque. Veintiún (21) estudiantes realizaron un dibujo y un texto explicativo del mismo, a partir de la pregunta ¿para ti qué es el ambiente? La categorización de las respuestas, permitió concluir que los resultados coinciden con lo reportado en la revisión de antecedentes: los estudiantes no establecen interacciones entre componentes del ambiente y centran sus respuestas en una visión antropocéntrica y naturalista del mismo. Estos resultados ratifican la necesidad de construir una propuesta pedagógica y didáctica que permita la comprensión del concepto ambiente desde una visión sistémica.
Enseñanza y aprendizaje en resolución de problemas: productos notables

Published: August 2021

Este artículo presenta resultados parciales de una investigación que tuvo como objetivo: establecer las características de las prácticas de enseñanza y aprendizaje en la resolución de problemas de factorización para el grado octavo, y caracterizar algunos aspectos de las prácticas de enseñanza y aprendizaje de resolución de problemas sobre productos notables. A partir del análisis de tres textos escolares y un cuestionario aplicado a 191 estudiantes, se hace la configuración epistémica y cognitiva del Enfoque Ontosemiótico. Los componentes de idoneidad epistémica, cognitiva y afectiva del enfoque dan relevancia al grado de representatividad del significado institucional, a la apropiación de los conocimientos y al uso de medios tecnológicos. La metodología fue de carácter mixto, y se usó el método de análisis de contenido. Entre los hallazgos se infiere que prevalece el modelo pedagógico tradicional, debido a que las clases de álgebra se fundamentan en las explicaciones de los docentes.

Este artículo de reflexión se deriva de la investigación “Competencia comunicativa oral por medio del uso del celular”, cuyo objetivo fue identificar cómo el uso del dispositivo móvil incide en la mejora de la competencia comunicativa oral de los estudiantes de grado noveno en la Institución Educativa Técnica de Nobsa, a través del análisis e interpretación sobre la manera como la tecnología ha influido en la calidad de la educación, sus aportes a la misma y los avances que se han obtenido en el desarrollo de habilidades cognitivas y competencias comunicativas. A partir de un sustento teórico, se busca delimitar los conceptos que dan soporte al proceso investigativo que posee un enfoque crítico social generando un cambio de pensamiento en el contexto educativo. Así mismo, el trabajo se enmarca en la Investigación Acción Educativa. En consecuencia, se presentan los impactos alcanzados con una propuesta que usó el celular como herramienta pedagógica, en talleres que lograron potenciar algunas de las habilidades necesarias para alcanzar una competencia comunicativa oral adecuada, y cómo se creó un ambiente en donde los estudiantes con motivación, trabajo colaborativo e innovación aprovecharon las características pedagógicas que puede brindar el dispositivo al ser multifuncional, asequible y portátil.

Published: August 2021

A través de la experiencia de los autores, es posible inferir que las anécdotas del abuelo, específicamente la intitulada: “el Diánchiro de Carboneras”, brinda algunas estrategias en la enseñanza ortográfica de las palabras oxítonas terminadas en vocal, y da pie a la escritura del presente artículo reflexivo, que tiene por objetivo mostrar la incidencia del relato mencionado en el aprendizaje del tildado en una estudiante de quinto grado en la sede rural Carboneras, de la institución Educativa Juana Caporal del municipio de Coper (Boyacá). Por medio del respaldo de referentes teóricos y la aplicación de actividades a partir de la anécdota, la cual fue aportada por la estudiante mencionada, se muestra la relación de la anécdota con la enseñanza de la ortografía de las palabras oxítonas, implementando actividades que pueden apreciarse con precisión en el asidero metodológico del presente artículo. Se relata la anécdota en un tiempo verbal (pretérito perfecto simple), que permite una comprensión práctica de la temática aquí abordada. Como resultado del aprendizaje del uso de la acentuación de dichas palabras, se ha evidenciado una escritura de textos con mayor sentido y coherencia.

En la educación actual, no se puede seguir haciendo las mismas tareas y aun así, pretender obtener resultados diferentes; por esto, es responsabilidad del maestro hacer una autocrítica de su labor pedagógica, para mejorarla. Teniendo en cuenta esto, el presente artículo de investigación expone brevemente la intervención, cuyo objetivo es, mejorar los procesos de comprensión de los estudiantes del Colegio Boyacá de Duitama, a través de la implementación y creación de los cuentos como herramienta didáctica. Para lograrlo, fue necesario primero, indagar sobre trabajos similares, junto con las teorías adecuadas que lo soporten, seguido de las fases de la Investigación-Acción-Educativa, obteniendo resultados significativos en cuanto a comprensión lectora se refiere; por ejemplo, los estudiantes en proceso de alfabetización ya pueden explicar con sus palabras, qué se hace más evidente en el momento que el estudiante escribe, con la intención de ser entendido por otros.
