Com a inserção de novas tecnologias e ferramentas em contextos escolares e de ensino, a utilização do uso de PowerPoint tornou-se bastante frequente pelos professores para facilitar as apresentações do seu conteúdo de uma forma dinâmica e visualmente mais atrativa. É perceptível que alguns docentes estão abertos ao novo, e percebem que há uma necessidade de acompanhar os avanços das tecnologias digitais que podem tornar-se aliadas no processo de ensino-aprendizagem. O objetivo deste trabalho é analisar slides produzidos e utilizados por professores de Geografia em sala de aula, de modo a identificar o saber tecnológico destes profissionais, quanto a criação e uso adequado da ferramenta do PowerPoint, na qualidade do seu potencial pedagógico. No que tange aos aspectos metodológicos, foi utilizado pesquisas bibliográficas que embasam acerca da ferramenta PowerPoint como recurso que disponibiliza funcionalidades para o uso de elementos textuais e audiovisuais. Além disso, foi desenvolvida uma pesquisa documental por meio de uma amostragem de slides selecionados para análise com o suporte de matrizes pré-estabelecidas. O PowerPoint é, portanto, uma das TICs que podem promover uma aprendizagem mais significativa, no entanto, é preciso que o docente alinhe o saber tecnológico e empregue sentido aos princípios pedagógicos inerentes à sua prática de ensino.

Published: October 2023

La presente investigación tuvo como objetivo establecer como índice de cosecha en frutos de palto cv. Hass los cambios en la pigmentación y color a nivel del ápice del fruto. Para ello desde la semana 23 después de máxima floración hasta la semana 29 se analizaron 30 frutos por semana de igual condición homogénea y similar tamaños tomados de panículas previamente marcadas al inicio de floración. Los cambios en la pigmentación y el color en el lado del ápice del fruto se evaluaron a través de los parámetros cromáticos L*, a*, b*, C*, h°, además se estimó el índice de color (CI) el índice de madurez de palta (AMI) la concentración de clorofilas a, b y total y la cuantificación del porcentaje de cobertura lenticelar (LC los cuales se relacionaron con el porcentaje de materia de los lados apical (DMA), central (DMC) y basal (DMB) del fruto. Los resultados muestran diferencias estadísticas entre los parámetros de color y la materia seca de la fruta, pero con coeficientes de correlación y determinación bajos. Siendo el matiz h° el único parámetro cromático que tuvo una mejor relación con el porcentaje de materia seca (r= -0.42). El comportamiento de la cobertura lenticelar con respecto a las semanas de evaluación y al porcentaje de materia seca del fruto se explican a través de una curva polinómica de tercer grado con coeficientes de relación (R2=0.97) y (R2=0.84) respectivamente. Ello permitiría estimar en base al porcentaje de cobertura lenticelar del ápice de los frutos de palto cv. Hass el porcentaje de materia seca de la pulpa debiendo la cobertura lenticelar ser al menos de 6.7 % para asegurar un porcentaje de materia seca (22 %) ideal para iniciar la cosecha de frutos. Respecto de las concentraciones de clorofila a, b y total, estas no presentaron diferencias ni variaciones en la zona apical del fruto.

Authors: Hidalgo Lozano Víctor , Vílchez-Perales Carlos 
Published: October 2023

The aim of this study was to evaluate the effect of the genotype on the deposition curve of the chemical components and fatty acid profile of carcass of guinea pigs of Peru and Cieneguilla genotypes. Forty-eight male guinea pigs (24 per genotype), randomly distributed in pens with three animals each per genotype were used. Management and feeding protocols, up to 32 wk of age, were similar for both genotypes. The deposition curve of the chemical components was determined using the Gompertz equation. Data of the fatty acid profile were submitted to analysis of varianza under a Randomized Complete Block Design using the SAS Studio Environment software, with a significance level of α = 0.05. The results showed that the asymptote of the moisture and protein content in the carcass of the Peru genotype was higher (P < 0.05) than that of Cieneguilla genotype, but not in the fat content, which was similar (P > 0.05) in both genotypes. Likewise, the function of the relationship between the maximum deposition rate of the three chemical components and the content at adulthood (k) was similar (P > 0.05) in the two genotypes. The age of maximum moisture deposition rate and total protein at the inflection point (ti) are lower than the maximum fat deposition rate in both genotypes. Regarding the fatty acid profile of the carcass, the content of total and individual saturated fatty acids was similar (p > 0.05) in the two genotypes was observed. However, the content of total monounsaturated fatty acids and oleic acid (C18:1C) were higher (p < 0.05) in the Cieneguilla genotype, while the content of total polyunsaturated fatty acids, linoleic and linolenic acids were higher (P < 0.05) in the carcass of guinea pigs of the Peru genotype. In conclusion, the asymptote of moisture content and crude protein in adulthood was higher (p < 0.05) in the Peru genotype. In saturated fatty acid content, there were no statistical differences between both genotypes, but the Cieneguilla genotype contains a higher (p < 0.05) percentage of monounsaturated fatty acids and the Peru genotype has a higher (p < 0.05) percentage of polyunsaturated fatty acids.
Albertina Carri: Remontar el archivo para una memoria desviada sobre el pasado reciente
Authors: Boido Pablo 
Published: September 2023

En el presente trabajo analizo un corpus de obras de la realizadora argentina Albertina Carri. Propongo poner en diálogo su último largometraje documental Cuatreros (2016) junto a la pieza Punto Impropio (2020) y Restos (2010) con la lectura performática titulada El affaire Velázquez (2013) y la instalación Investigación del cuatrerismo (2015). Estas realizaciones están construidas a partir de documentos tomados de distintos acervos. Pueden entenderse como un diálogo en ausencia que la directora intenta con su padre­madre desaparecidos por la última dictadura cívico-militar. Estas propuestas, además, son un intento de repensar la herencia o legado de sus progenitores partiendo desde los despojos. Allí asoma una forma de montaje desviado sobre los archivos construyendo otro tipo de narrativas intermediales que proponen repensar los vínculos íntimos y familiares.
This paper analyses a corpus of works by Argentine filmmaker Albertina Carri. I propose to put into dialogue her latest documentary Cuatreros (2016) together with the piece Punto Impropio (2020) and Restos (2010) using the performative lecture El affaire Velázquez (2013) and the installation Investigación del cuatrerismo (2015). These works are constructed from documents taken from different collections. They can be understood as a dialogue in absence that the director attempts with her parents, who were disappeared during the last civil-military dictatorship in Argentina. These proposals are also attempts to rethink the inheritance or legacy of her parents based on the remains. Somehow, there emerges a form of deflected montage on the archives, constructing another type of intermedial narrative that proposes to rethink intimate and family ties.
Automated Paper Screening for Clinical Reviews Using Large Language Models: Data Analysis Study
Authors: Guo Eddie , Gupta Mehul , Deng Jiawen , Park Ye-Jean , Paget Michael , Naugler Christopher 
Published: September 2023

Background
The systematic review of clinical research papers is a labor-intensive and time-consuming process that often involves the screening of thousands of titles and abstracts. The accuracy and efficiency of this process are critical for the quality of the review and subsequent health care decisions. Traditional methods rely heavily on human reviewers, often requiring a significant investment of time and resources.

Objective
This study aims to assess the performance of the OpenAI generative pretrained transformer (GPT) and GPT-4 application programming interfaces (APIs) in accurately and efficiently identifying relevant titles and abstracts from real-world clinical review data sets and comparing their performance against ground truth labeling by 2 independent human reviewers.

Methods
We introduce a novel workflow using the Chat GPT and GPT-4 APIs for screening titles and abstracts in clinical reviews. A Python script was created to make calls to the API with the screening criteria in natural language and a corpus of title and abstract data sets filtered by a minimum of 2 human reviewers. We compared the performance of our model against human-reviewed papers across 6 review papers, screening over 24,000 titles and abstracts.

Results
Our results show an accuracy of 0.91, a macro F1-score of 0.60, a sensitivity of excluded papers of 0.91, and a sensitivity of included papers of 0.76. The interrater variability between 2 independent human screeners was κ=0.46, and the prevalence and bias-adjusted κ between our proposed methods and the consensus-based human decisions was κ=0.96. On a randomly selected subset of papers, the GPT models demonstrated the ability to provide reasoning for their decisions and corrected their initial decisions upon being asked to explain their reasoning for incorrect classifications.

Conclusions
Large language models have the potential to streamline the clinical review process, save valuable time and effort for researchers, and contribute to the overall quality of clinical reviews. By prioritizing the workflow and acting as an aid rather than a replacement for researchers and reviewers, models such as GPT-4 can enhance efficiency and lead to more accurate and reliable conclusions in medical research.
Heavy grazing led to the decrease of competitive intensity relationships among dominant populations of clustered grasses in a desert steppe
Authors: Wang Zihan , Lv Shijie , Liu Hongmei , Chen Chen , Li Zhiguo , Wang Zhongwu , Han Guodong 
Published: October 2023

Stipa breviflora (Stipa breviflora Griseb.) and Cleistogenes songorica
(Cleistogenes songorica (Roshev.) Ohwi) are two dominant species in the
critically important desert steppe of northern China. Under the
interference of grazing, the two species will have the phenomenon of
plant cluster fragmentation to varying degrees. Therefore, when the two
plant populations appear in the same plant community, what changes will
happen in the inter-specific relationship during grazing has important
guiding significance for its regulation of plant community and function.
To study this, we observed populations of wild S. breviflora and C.
songorica in field under a suite of grazing intensities and at a variety
of scales. The density changes of dominant species S. breviflora and C.
songorica in desert steppe in Inner Mongolia were studied under four
grazing intensities (no grazing, CK, 0 sheep·ha-1·half year-1, light
grazing, LG, 0.93 sheep·ha-1·half year-1, moderate grazing, MG, 1.82
sheep·ha-1·half year-1, heavy grazing, HG, 2.71 sheep·ha-1·half year-1)
and six scales (5 cm×5 cm, 10 cm×10 cm, 20 cm×20 cm, 25 cm×25 cm, 50
cm×50 cm and 100 cm×100 cm). Results showed that grazing changes the
relationship between dominant species. With the increase of grazing
intensity, the densities of S. breviflora and C. songorica increased,
and the increase was more obvious with the increase of scale. Under
heavy grazing conditions, the dominant populations of clustered grasses
in Inner Mongolia desert steppe resisted the interference of
high-intensity grazing by reducing inter-specific competition ability
(increasing inter-specific affinity).

Published: October 2023

Introduction. This article, as one of the few research articles, explores the interrelation between creativity and participation in social network. It also studies the level of reflection in active virtual space users. The need for investigation is justified by the explosion in the number of social media users over the 2021 to 2022 period.Purpose. In our work, we will do research on the relationship between activity on social media and levels of reflection and creativity in active social media users.Materials and Methods. To achieve practical objectives, we used several psychological methods: The Differential Test of Reflexivity (DTR) by D. A. Leontiev and E. N. Osin, Diagnostics of Trait Creativity by E. E. Tunik, and the authors’ questionnaire for social media participation measure. The Mann-Whitney test and the Pearson correlation coefficient were chosen as mathematical statistics tools. 145 respondents of different age and occupation, students of the “Media Communications and Multimedia Technologies” faculty, and freelancers participated in the study.Results. We found that active users have higher scores on the “Quasi-reflection” scale. They distract themselves by diving in a virtual world that is full of affairs and experience, but has no relation to the real-life concerns. The level of creativity in active and inactive social media users does not have a significant difference. Discussion and Conclusion. The data obtained do not go in accordance with previously conducted studies on the interrelation between creativity and reflection in social media users, nor between activity in the network and reflection level. Therefore, the present research pushes the envelope on psychological characteristics of the personality, reveal themselves in social media, and influence behaviour in virtual social space. Our work expands the diagnostic program for research on psychological predictors of the information behaviour of the personality.
Reflection as a Predictor of Attitude Towards Time Perspective
Authors: Godunov M. V. , Komerova N. E. 
Published: October 2023

Introduction. Reflection stands as an ability to self-analyze, critically comprehend the present, and predict the future. It helps a person to cope with a situation of uncertainty, therefore, justifies the study on this matter. In our article, we considered the works of Russian and foreign scientists regarding reflection, self-observation, and attitude towards time perspective. However, it appears that the connection between leading type of reflection and attitude towards time perspective remains undiscovered.Purpose. We will study the relationship between reflection type and attitude towards time perspective in youth.Materials and Methods. The following methods were chosen: the Zimbardo Time Perspective Inventory; “The Image of a Possible Future” method (V. N. Petrova), “Differential Type of Reflection” (D. A. Leontiev, E. M. Lapteva, E. N. Osin, A. Z. Salikhova); and “Life-Purpose Orientations” test (D. A. Leontiev). For the statistical analysis, we used Kruskall-Wallis H test.Results. Examination of the answers (n=228) revealed the differences in attitude towards time perspective in the respondents with different types of reflection (systematic reflection, quasi-reflection, introspection). Thus, quasi-reflection as a leading reflection type expresses itself in higher focus on the future, daydreaming about it, and searching for the hedonism in the present. The predominance of introspection is seen through difficulties in understanding past experiences, belief in the force of circumstances, and a lower level of satisfaction with the process and result of life. Systematic reflection distinguishes itself in high level of self-awareness, personal maturity, shaped goals in life, and life-purpose orientations clearness.Discussion and Conclusion. In this section, we justify the accuracy of the results obtained. Significant differences were found in the groups: “fatalistic present”, “life process”, “life productivity”, “locus of control self” and “locus of control life”. It confirms that reflection serves as one of the factors associated with attitude towards time perspective. The results can be applied in study courses made for university students’ subject “Psychology of the Life Path”.

Introduction. The article is devoted to the aspects of psychological support in the creation of a common educational space for Donbas and the Russian Federation considering the new social and political conditions. The “canceling” of the Russian culture from the side of western countries and the strain geopolitical situation justify the urgency of the creation and further development of the space for Donbas and the Russian Federation. In this section, we focus on the role of psychological support in the establishment of the new educational system considering increased stress conditions.Purpose. In our work, we will consider conceptual issues and fundamental principles of psychological support modernization for the development of the common educational space for Donbas and the Russian Federation.Theoretical Justification. The main purposes of modernization and enhancement of the psychological support system in educational establishments are described there. Special focus is put on educational psychologist’s functions in teaching facilities: diagnostics of students’ psychoemotional state; consulting for parents and teachers; the creation of friendly psychological environment; psychological protection for school and university students, and others. There are issues that negatively impact effective psychological support of students: the lack of awareness regarding the presence of such help in the educational establishment; students’ low level of trust to psychologists and the fear that third-party entities can possess the information obtained during the counselling; as well as the lack of easy and swift access to a psychologist.Discussion. We suggest the development of express psychological support strategies for educational establishments and the creation of a psychological counseling service. Early identification of potential problem with the help of preventive diagnostic means, development of rapid response algorithm, establishment of organizational aspects, creation of suitable conditions for privacy protection, as well as access easement to psychological support, represent the assembly that configures foundation of the service mentioned above.

Authors: Kireev S. O. , Lebedev A. R. , Korchagina M. V. 
Published: October 2023

Introduction. The performance and reliability of gerotor hydraulic machines depend on the geometry of the cycloidal gearing profile. The existing methods of calculating and optimizing the profile parameters are cumbersome, multicriteria and difficult for practical application. Therefore, the problem of creating the methodology for calculating the parameters of the gerotor machine profile suitable for engineering calculations at the stage of conceptual design is a challenge. In this regard, the objective of this work was to modernize the methodology for designing the geometry of the profiles of the end section of hypocycloidal gears used in gerotor hydraulic machines, and to analyze the possibilities of their optimization during preliminary design. In the course of the study, the Mathcad computer mathematics system was used; numerical experiments were carried out to study the influence of geometric profile parameters on the performance and operability of the gerotor hydraulic machine, based on the data obtained and analyzed; recommendations for the design of optimal profiles of the end section of gerotor hydraulic machines were developed.Materials and Methods. Materials included known methods of profile parameters calculation, based on application of classical formulas of hypocycloidal equidistant used for outlining profiles of teeth of working elements of gerotor machines. The basic research method was modeling the gerotor machine profile using Mathcad computer mathematics system. Calculated data were obtained for the selected ranges of varying parameters, processed through the univariate regression analysis.Results. An algorithm for analyzing the tooth profile smoothness was developed. Two target parameters were defined: the cross-sectional area of the end profile, which affects the productivity; the smallest reduced radius of contact that determines operability of the working body. A technique for calculating the target parameters at the early stage of design was proposed. A number of optimal values of profile parameters according to the criteria of productivity and operability of gerotor machine was obtained. The dependences providing the optimum values of profile parameters at the stage of designing were constructed.Discussion and Conclusion. The developed methodology makes it possible to obtain an assessment of the performance and operability of the gerotor hydraulic machine at the design stage of the working body. The research results can be used in mechanical engineering when designing gerotor hydraulic machines in order to improve their technical and operational characteristics.

Published: October 2023

Introduction. The analysis of approaches to tracking the human body identified problems when capturing movements in a three-dimensional coordinate system. The prospects of motion capture systems based on computer vision are noted. In existing studies on markerless motion capture systems, positioning is considered only in two-dimensional space. Therefore, the research objective is to increase the accuracy of determining the coordinates of the human body in three-dimensional coordinates through developing a motion capture method based on computer vision and triangulation algorithms.Materials and Methods. A method of motion capture was presented, including calibration of several cameras and formalization of procedures for detecting a person in a frame using a convolutional neural network. Based on the skeletal points obtained from the neural network, a three-dimensional reconstruction of the human body model was carried out using various triangulation algorithms.Results. Experimental studies have been carried out comparing four triangulation algorithms: direct linear transfer, linear least squares method, L2 triangulation, and polynomial methods. The optimal triangulation algorithm (polynomial) was determined, providing an error of no more than 2.5 pixels or 1.67 centimeters.Discussion and Conclusion. The shortcomings of existing motion capture systems were revealed. The proposed method was aimed at improving the accuracy of motion capture in three-dimensional coordinates using computer vision. The results obtained were integrated into the human body positioning software in three-dimensional coordinates for use in virtual simulators, motion capture systems and remote monitoring.
