The Educator, Interrupted
Authors: O'Brien Elizabeth
Published: January 2023

Emerging from the suggestion that initial teacher education in Ireland shift to a version of the clinical school model, I ask how can we think about the in-school experience of student teachers in terms of those capabilities which promote subjectivity? In this paper I share a philosophical perspective on the educational value of the in-school experience during initial teacher education. I suggest that the university’s presence in school ought to be carefully considered. A closer relationship has implications for the breadth and possibility of the in-school experience of student teachers, and as such the development of the educator’s sense of their own significance and the significance of others. I do so by engaging with the philosophy of Hannah Arendt on plurality and beginnings, and Gert Biesta on subjectification and ‘subject-ness’, to consider the significance of the nature of existence in the world to the development of the individual as a subject of freedom and responsibility.
Interruption is proposed as an educational capability, which contributes in a meaningful way to life as an educator in the world of the school and requires open authentic real-world experience to flourish. We can be interrupted from outside, interrupt another person or a moment, or interrupt ourselves from within. It calls for a slowing down, for listening and attention. Interruption recurs. Furthermore, the educator may be the one who interrupts, who resists. The educator capable of Interruption values pause and consideration, foregrounding thoughtful resistance, and taking their place as a subject in the world.

Published: January 2023

A pandemia de Covid-19 gerou distintos impactos e desdobramentos em diversas temáticas e âmbitos das relações internacionais que demandaram dos Estados e dos blocos regionais ações diante de seus efeitos sanitários, políticos, sociais e econômicos. Este artigo tem como objetivo mapear e analisar os princípios comuns sobre a temática migratória que foram propostas no Mercado Comum do Sul durante os dois anos iniciais da pandemia da Covid-19 (2020 e 2021). Para lográ-lo, realizamos uma pesquisa qualitativa e exploratória utilizando fontes bibliográficas e documentais oficiais promulgados pelo bloco e por seus países-membros. Observamos que embora o bloco tenha sido um espaço importante de discussão e proposição de medidas conjuntas acerca da temática e do combate ao vírus, em alguns momentos da pandemia de Covid-19 seus Estados-membros adotaram medidas domésticas que contrastaram com os arranjos acordados dentro do Mercosul mesmo em períodos anteriores à pandemia.

Authors: Argüelles Indira López
Published: January 2023

Los efectos de la pandemia en la economía mundial han sido agudos y acarrearon notables reacomodos geoeconómicos, los que se han reorientado con el conflicto de Ucrania. Esta coyuntura tiene elementos favorables  para la región de  América Latina y  otros retadores;  en el plano geopolítico tal y como sucedió con el ascenso del poder Imperial de EE. UU, a finales del siglo XIX, las economías emergentes, para erigirse como superpotencias globales deberán pescar en aguas de esta región, por lo que se prevé en el mediano plazo,  nuevas batallas geopolíticas entre las nuevas economías emergentes ( China, Rusia, India, Turquía, Irán, Arabia Saudita, o cualquier otro)  y las tradicionales. Conocer las posibles formas de asociación entre estas economías emergentes y América Latina, así como adentrarnos en la identificación de cuáles deben ser los elementos esenciales de estas nuevas interacciones, resultará clave, por lo que el problema de investigación en este proyecto básico es, ¿cuáles son las nuevas dinámicas geopolíticas que debe encarar la humanidad? Qué retos encaran nuestros países y cuáles son las soluciones conocidas y abordadas hasta el momento y cuáles de ellas pudieran ser las más útiles a nuestros países. Como objetivo nos proponemos informar a decisores políticos que estas batallas pudieran conducir a nuevos patrones energéticos, en los que los recursos naturales de nuestros países vuelvan a ser disputados, de igual forma estos combustibles impulsarán nuevas tecnologías que pueden ser de uso masivo.  Consideramos que ante estas problemáticas, la región necesita de líderes leales al proyecto nación latinoamericana para potenciar una reinserción global y sobre todo emprender esenciales trasformaciones socioeconómicas, balancear los nexos con todas las potencias, y desde la autodeterminación buscar    autonomía y soberanía energética como vía garantes del desarrollo.

Authors: Kolb Jennifer M. , Davis Christian , Williams J. Lucas , Holub Jennifer , Shaheen Nicholas , Wani Sachin
Published: January 2023

INTRODUCTION:

Variability in adherence rates to the Seattle protocol and to surveillance interval recommendations, established quality indicators (QIs) in Barrett's esophagus (BE), is unknown.

METHODS:

We evaluated endoscopist and site-based adherence rates to these QIs from January 2018 to May 2021 using the GI Quality Improvement Consortium national registry with matched endoscopy and pathology data.

RESULTS:

Across 153 practices with 572 endoscopists performing 20,155 endoscopies, adherence to the Seattle protocol varied by endoscopists (median 93.8%, IQR 18.9%) and by site (median 90.0%, IQR 20.1%). Adherence to appropriate surveillance intervals for nondysplastic BE also varied by endoscopist (median 82.4%, IQR 36.3%) and site (median 77.2%, IQR 29.8%). The overall dysplasia detection rate was 3.1% and varied among endoscopists and sites.

DISCUSSION:

These US population-based results can serve as a benchmark for quality initiatives and intervention trials aimed at improving outcomes for patients with BE.

Published: January 2023

INTRODUCTION:

The relationships between sedentary behavior patterns and nonalcoholic fatty liver disease (NAFLD) in older adults are not well investigated.

METHODS:

This population-based study included 1,899 rural-dwelling adults (aged 60 years or older). We assessed sedentary parameters with ActiGraph and defined NAFLD using ultrasonography.

RESULTS:

Long total and prolonged sedentary time were associated with increased likelihoods of NAFLD, whereas engaging more breaks per sedentary hour and reallocating sedentary time to light-intensity physical activity were associated with reduced likelihoods of NAFLD (Plinear <0.05).

DISCUSSION:

Shorter sedentary time, engaging more frequent breaks in sedentary behavior, and replacing sedentary time with physical activity are associated with reduced likelihoods of NAFLD in older adults.
Does Gender Inclusivity Matter for Economic Growth in South Africa? An ARDL approach
Authors: Makua Khutso Baltimore , Malungane Neo , Mswephu Khayakazi , Sadiki Ronewa Candy
Published: January 2023

With inequality at the forefront of economic development, this paper examined the impact of gender inequality on economic growth in South Africa. Different gender dimensions were considered, including female education, female labor force participation, fertility, and the representation of women in the political arena (democracy). The research applied a quantitative approach (Autoregressive Distributive lag) (ARDL) with secondary data on the proportion of all variables spanning from 1989 to 2019. The results revealed that high fertility negatively affects economic growth. Moreover, the effects are positive when women have greater access to secondary education and the labor market. However, an unorthodox finding from the study reveals that the effects are negative when women have access to political seats in parliament. The paper recommends that policymakers should focus on guaranteeing obligatory secondary education for females in the country. Additionally, policymakers should introduce measures that favor appointing and absorbing women in qualified jobs.

Published: January 2023

The article presents the results of studies of polymer samples (PVC) under thermal exposure in a muffle furnace, by measuring color characteristics using a model of color decomposition into RGB components. Under thermal action, chemical and physical changes occur in polymers. The degree of thermal damage depends on the time and temperature of exposure [1]. The aim of the work was to establish the dependence of color characteristics in the RGB system on the temperature and time of exposure to PVC samples. A criterion for controlling the degree of thermal damage and a device for implementing the method are proposed. The device is based on the TCS3472 color sensor and a programmable logic controller. The data obtained can be used in the investigation of fires at objects with polymer finishes when detecting fire propagation paths, as well as monitoring the degree of thermal damage to polymers during various technological processes.

CORRECTION OF THE VECTOR CONTROL SYSTEM OF AN ASYNCHRONOUS ELECTRIC DRIVE BY MONITORING AND REGULATING THE COORDINATES OF THE STATOR CURRENT VECTOR
Authors: Meshcheryakov V. N. , Kryukov O. V. , Danilova O. V.
Published: January 2023

An adjustable asynchronous electric drive is considered, in which the vector control system is supplemented with correction blocks acting on the magnitude of the longitudinal (magnetizing) component of the stator current vector. It is shown that it is advisable to carry out the action of the correction system with a reduced static load of the motor in steady-state mode, due to which, at fixed values of the static moment, a decrease in the stator current is ensured. A feature of the construction of the proposed corrected vector control system is the use of correction blocks that monitor the longitudinal and transverse components of the stator current, which allows you to determine the tangent of the angle between the vectors of the stator current and its longitudinal component, as well as the mismatch of the received and set values, and in the function of the mismatch value to change the signal setting the longitudinal component of the stator current. The effect and advantages of the proposed correction system of an asynchronous electric drive with vector control are investigated by simulation modeling.

METHODOLOGY FOR THE FORMATION OF INFORMATION SYSTEMS FALSE NETWORK TRAFFIC FOR PROTECTION AGAINST NETWORK RECONNAISSANCE
Authors: Sokolovsky S. P. , Telenga A. P.
Published: January 2023

Simulation of false network traffic in order to protect the structural and functional characteristics of information systems is a difficult task in view of the self-similarity of its statistical properties in IP networks, not only in the current moment, but also retrospectively. A Hurst index based algorithm for assessing the degree of self-similarity of network traffic of information systems has been proposed. The connection between the fractal dimension of the attractor of the model of information system functioning and the Hurst index is shown. A technique has been developed to substantiate the characteristics of false network traffic to simulate the functioning of information systems in the process of reconfiguration of their structural and functional characteristics caused by an intruder conducting network reconnaissance. The methodology allows to solve the problem of improving the protection of information systems from network reconnaissance by providing the maximum likelihood of false network traffic by pseudophase reconstruction of the dynamic system attractor, approximating the time series of information traffic of the protected object. The approaches to the description of the network traffic of the information system are considered, the parameters determining the network interaction between the two nodes of the data transmission network are selected as follows: source IP-address, source port, destination IP-address, destination port, protocol, packet size, duration of connection. The process of functioning of information system in different situations is formalized and the dependences allowing to synthesize parameters of false network traffic, statistically similar to the reference ones are received.

Authors: Brekotkina E. S. , Pavlov A. S. , Pavlov S. V , Trubin V. D. , Khristodulo O. I.
Published: January 2023

Management of complex distributed systems, at present, is carried out using information technologies designed to collect and manage a large amount of heterogeneous information of an organization or institution. The computer infrastructure of such systems is also a complex distributed system, and information about the location and mutual arrangement of its individual components, as well as the location of the associated infrastructure and main users, is essential for its high-quality functioning. This paper proposes a method for mining spatial data to formalize the process of creating specialized databases for the implementation (creation) of individual subsystems as part of complex distributed information systems. The results of the application of this method for the construction of one of the subsystems, namely, the subsystem of information support for the management of computer infrastructure, as part of a complex distributed information system, are presented on the example of the geoinformation system of the Ufa State Aviation Technical University. The proposed approach to intelligent analysis and representation of spatial data can be used to build complex information systems in significantly distributed organizational and infrastructural systems.
NUMBERS-TYPES OF THE CLASSIFIER OF BIG DATA OBJECTS OF THE SOCIO-ECONOMIC SYSTEM
Authors: Konovalov V. A.
Published: January 2023

The N-scheme developed to replace the well-known g-scheme of the normal Markov algorithm is investigated. The numbers-types of the classifier of big data objects of socio-economic systems are introduced, theoretically substantiated and synthesized, which determine the N-scheme of the Markov algorithm. The purpose of such studies is determined – this is to find scientific and technical ways to counter money laundering, for which it is necessary to analyze a large amount of data on economic interactions (relationships) of individuals and legal entities that make up various socio-economic systems, where g-schemes are more expressive than the wellknown Markov g-schemes. It has been established that for this it is advisable to study the properties of combinations of initial, terminal and isomorphic morphisms (relationships) of objects of socio-economic systems. It was found that each word from the Markov alphabet A can be characterized by the morphism number n, which in turn can be represented as one of the letters of the alphabet M =tjilckmg, where its association method is defined by M, with the value f in the unit of measure “type”. It is noted that then for each object it is possible to collect data on all its initial, terminal, isomorphic relationships (interactions) and represent them in the form of w-syllables and w-words from letters of the alphabet M, completing the formation of the N-scheme of the Markov algorithm. Examples of categories and their type numbers are given, composed of letters of the alphabet M. It is noted that a certain lattice is formed from the type numbers, which can be used to solve NP-complete problems. It has been found that it is advisable to evaluate superlarge w-words of numbers-types, since they can contain fragments that are responsible for the entry of the algorithm into an infinite loop.
METHODICAL APPARATUS FOR ENSURING THE CORRECTION OF SINGLE ERRORS AND DETECTION OF DOUBLE ERRORS IN STORAGE DEVICES
Authors: Pavlov A. A. , Tsar’kov A. N. , Romanenko A. Yu. , Romanenko Yu. A. , Makeev M. I. , Pavlov F. A.
Published: January 2023

The analysis of errors that occur during the operation of static storage devices (SD) is carried out. The conclusion is drawn that single and double errors are most likely to occur in memory devices (single errors appear with a probability of up to 80 %, double errors up to 20 – 25 %, and errors of other multiplicity account for up to 2 %). Methods for protecting storage devices from single and double errors are considered. It has been established that at present, for the correction of single errors and the detection of double errors, a modified Hamming code is widely used, which uses for this purpose an additional parity bit for all bits of the code set. The necessity of developing a code that corrects single errors and detects double errors while reducing information redundancy is substantiated. Regularities have been identified that make it possible to form rules for encoding information, and when decoding, to form three additional checks for an error sign to determine erroneous bits in the event of indistinguishable error syndromes. The corrective ability of the proposed method of information coding is investigated. It has been established that the proposed code allows correcting all single errors, detecting all double errors and, at the same time, correcting some of the double errors that simultaneously occur in information and check bits. A regular information coding procedure is described for correcting single and detecting double errors while reducing information redundancy by one check bit and, consequently, reducing hardware costs associated with storing the values of check bits in a memory device. A comparative evaluation of the detection ability and information redundancy of the proposed method with a modified Hamming code is carried out using the example of coding an 11-bit information word. It has been established that for the code (15,11), the implementation of the proposed method makes it possible to detect all single and double errors, correct 100 % of single errors and 27 % of double errors, and use four check digits for these purposes (one less check digit than modified Hamming code). The conclusion is made that the reduction of information redundancy makes it possible to increase the code speed and reduce hardware costs associated with storing the values of a given bit in a memory device and, therefore, increase the probability of failure-free operation and reliability of the memory device operation while reducing information and hardware redundancy.
DEVELOPMENT OF A FUZZY MODEL OF A STUDENT INTELLIGENT TEACHING SYSTEM OF TECHNICAL DISCIPLINE
Authors: Tagirova L. F. , Zubkova T. M.
Published: January 2023

The development of computer technology provides great opportunities for modernizing the learning process. Teachers are actively introducing various electronic learning systems, the leading positions among which are occupied by intelligent learning systems. One of the tasks of developing an intelligent learning system is the implementation of dynamic adaptation of educational material to the level of knowledge of students. Therefore, it is necessary that it includes a student model that reflects the characteristics of the student that are important for managing the learning process. The paper describes the development of a fuzzy model of a student in teaching intelligent systems. This model is based on the concept of “student status”, the parameters of which are the level of mastering the discipline and the student’s personal qualities. A distinctive feature of the proposed fuzzy model is the joint use of the stereotypical and overlay models of the student. In addition, the developed fuzzy model is based not only on the assessment of student’s knowledge, but takes into account the personal qualities of students (responsibility, desire for self-learning and development, perseverance, attentiveness, stress tolerance). The paper proposes the use of a fuzzy expert system as a tool for decision support in determining the status of a student. During the operation of the expert system, the characteristics of students are evaluated, which are compared with the rules of the fuzzy rule base. When implementing a logical inference, a student is assigned one of the possible status values (beginner, trainee, master, professional and expert). At the final step, the student is offered to study the theoretical material of the discipline adapted to his characteristics.

The features of the architecture of the convolutional neural network U-net are described. An analysis of the CNN U-net was carried out, based on the analysis, a rationale was given for choosing the CNN U-net as the main architecture for using and building subsequent created and analyzed models of cert neural networks to solve the problem of segmentation of medical images. The analysis of architectures of convolutional neural networks, which can be used as convolutional layers in CNN U-net, has been carried out. Based on the analysis, three architectures of convolutional neural networks were selected and described suitable for use as convolutional layers in CNN U-net. Using CNN U-net and three selected convolutional neural networks (“resnet34”, “inceptionv3” and “vgg16”), three neural network models for medical image segmentation were created. The training and testing of the created models of neural networks was carried out. Based on the results of training and testing, an analysis of the obtained indicators was carried out. Experiments were carried out with each of the three constructed models (segmentation of images from the validation set was performed and segmented images were presented). Based on the testing indicators and empirical data obtained from the results of the experiments, the most suitable neural network model created for solving the problem of medical image segmentation was determined. The algorithm for segmentation of medical images has been improved. An algorithm is described that uses the predictions of all created models of neural networks, which demonstrated a more accurate result than each of the considered models separately.

The peculiarity of the local assessment is that it is a dynamic parameter that characterizes the state of the body at a given point in time, and to obtain it, the Holter technology was used with the formation of digital files of heart rate variability (HRV) indicators recorded by a monitoring system with a set of four clusters each, spaced in time and containing data of implementations of flight tasks of the initial, middle and final phases of the flight. Necessary and sufficient to display the dynamics of HRV was the time duration of the clusters of 300 seconds, which made it possible to obtain the necessary digital content of the HRV parameters in 40…60 minutes of flight time. The informational significance of the data obtained is determined by the content of the implemented flight tasks for various purposes. The capabilities of the semi-natural modeling complex made it possible to create complex and special flight situations, that negatively affect the psycho-physiological state of the operator. Local estimates of the tension index were obtained, which generally fell within the range of acceptable values, although in special cases of flight they went into the range characteristic of the states of effective adaptation of the organism. Levels were also recorded, signaling the exhaustion of the body’s capabilities, fatigue and a reduced level of performance. A generalized integral indicator of tension is proposed – the reserve coefficient of the body R as a linear combination of local estimates of tension: the maximum local intensity index achieved in a given flight cycle, “passport” indicator of the operator’s tension, fixed before the flight task at the stage of pre-flight preparation, and an indicator of the current tension at a particular point in time in a particular situation. At the same time, the smaller the value of R, the smaller the reserve of the organism. The obtained experimental integral estimates of the body reserve in the process of operator activity are not only of research interest, but also of interest in practical applications in the tasks of ergonomic expertise of aviation equipment and the design of the operator-pilot activity.

The article outlines methods for efficient computation of attributes in a table-driven top-down parsing process. This methods are based on the introduction of a stack of attributes into the parser. Semantic actions using this stack are defined by one of three methods. The first method is based on the fact that two parsers: table-driven and recursive descent parsers have the same use of depth first traversal. Therefore, the mechanisms for computing attributes in recursive descent are also applicable in a table-driven parser. Then the attribute stack will act like a frame stack of function calls. The second method assumes that the attribute stack is the memory of an abstract machine. For the source language of the translator, the structural-operational semantics is specified, which puts the translation result in line with the language constructions. The semantic actions of the translation scheme are implemented as analyzing and applying rules of an abstract machine built on the basis of structural-operational semantics. The third method assumes that an abstract syntax tree in postfix form will be formed in the attribute stack. Semantic actions for the attribute stack are built in such a way that the expressions formed on the stack are evaluated as far as possible. The article shows that the application of the three proposed methods to the scheme of translation of arithmetic expressions gives the same result. The proposed methods can significantly reduce the amount of memory used and make the design of the translator more understandable.

Algorithms for monitoring moving objects are of great interest in the field of computer vision. The paper presents the results of the development and research of image analysis algorithms for monitoring vehicles in a video stream. Currently, the monitoring of vehicles, especially in production areas, is performed manually by operators. Developing practical applications of video analytics will reduce operator workload, increase speed and accuracy of decision making, and automate the process of collecting and generating reporting statistics on plant transportation. Research was conducted and a video analysis system was developed that includes detection algorithms, classifications by vehicle type, color, and model, and vehicle tracking in the video stream. It should be noted that the architecture of existing solutions, as a rule, is monolithic and does not allow to refine and embed new unique modules to solve emerging problems. In modern conditions, in order to cover new requirements in the field of object recognition and detection in large vehicle flows, it is necessary to develop and implement new solutions. The results of the work of the algorithms on real images of existing datasets and the developed own dataset are presented. In this case, the objects are under different lighting conditions, in different angles, are rebuilt in the stream, there is an overlap of objects. The developed system has a microservice architecture, which allows to adapt the solutions to specific tasks.
ALGORITHM OF STRUCTURAL-PARAMETRIC SYNTHESIS OF VISUALIZATION SYSTEMS OF TRAINING COMPLEXES

Published: January 2023

This article discusses the solution of the problem of increasing the economic efficiency and quality of training of ergatic systems personnel when using training complexes by choosing the optimal parameters of the visualization system. The specificity of the task lies in the fact that in the course of its solution, the system structure is first determined, reflecting the categories of visualization equipment used, as well as the software implementation of the virtual representation at a high level of abstraction. In addition, the final solution to the problem of structural-parametric synthesis should ensure not only the maximum possible quality of information display when the conditions for economic and time costs are met, but also guarantee the necessary level of professional training. To determine the most optimal structure of the visualization system, an algorithm of structural-parametric synthesis of the visualization system has been developed, taking into account all of the above aspects of creating a training complex. Based on the proposed algorithm, a simulator visualization system for training miners based on a VR helmet and VR controllers has been developed. The training complex allows you to work out such actions as notification of the occurrence of an emergency situation, search for an escape route, as well as the use of fire extinguishing skills. After obtaining the optimal solution to the problem of synthesizing a simulator for training a miner, experimental studies were conducted to test the algorithm’s operability with a new focus group of subjects. As an alternative, a more cost-effective solution based on a monitor and a keyboard with a mouse was considered. The results of the comparison showed that the alternative solution does not provide the necessary level of competence formation in a timely manner. The proposed simulator allows you to get both the best quality of mastering and shorter terms of mastering.

Published: January 2023

Building computer models of dynamic canal surfaces is a special case when implemented in CAD-systems since existing methods of surface modeling of such type are concentrated mostly on obtaining analytical expressions such as equations for the surface itself or its sections. The article introduces a constructive method of building models based on plane and spatial geometric constructions. The paper provides the analysis of given surface parameters, constructive algorithms for setting up a geometric correspondence between the graph of the cross-sectional area and the directrix, constructing of cross-section for the given point on the cross-section area graph as well as placement the cross-sections in three dimensions and determining spatial coordinates of the points on the surface. This allows to build a structured point cloud of a dynamic canal surface of required density and build a model of it in CAD-systems. Suggested constructive algorithms are applied with the help of GC language commands. The paper provides fragments of construction subroutines as well as examples of created models of dynamic canal surfaces. The approach proposed provides for automation of building models of surfaces in CAD-systems, moreover it is flexible to adjust according to the given parameters such as a directrix shape, cross-section area graph, a cross-section shape, etc.
