APPLICATION OF COMPUTER MODELING TO ASSESS THE NOISE IMMUNITY OF DIGITAL COMMUNICATION LINES WITH M-ARY FREQUENCY-SHIFT-KEYED
Authors: Fomin A. V. , Voznyuk V. V. , Baranov V. M.
Published: December 2021

The article considers the process of unintended noise interference with variable frequency and spectrum width values on a digital communication line with multi-position frequency manipulation. To conduct research in the modeling environment Matlab developed software model allows to estimate the influence of noise of various structures to receive signals from multiple frequency shift keying and obtain the dependence of the probability of bit error against signal-to-noise. The transmitter model allows you to generate a high-frequency signal manipulated by the frequency of an information message, which is represented in the work as a set of ASCIIRU-code characters. The receiver model is based on the scheme of optimal coherent reception of a frequency-manipulated signal. To improve the quality of signal reception, the transmitter and receiver models include: an interference-resistant encoder and decoder, an interleaver and deinterleaver, and an amplitude limiter. The interference model allows you to form a noise interference with a given band, with random amplitudes distributed according to the Rayleigh law, and random phases according to a uniform law in the interval [0, 2π]. Evaluation of the noise immunity of a signal receiver with multi-position frequency manipulation is performed on the basis of simulation for various noise parameters. Patterns of interference that have the most destructive effect on the receiver of signals with multi-position frequency manipulation are revealed. The protective ratio is used as an indicator of the effectiveness of radio-electronic protection, and the probability of a symbolic error (p* = 0.01) is the criterion for making a decision about the operability of the radio line.
NEURAL NETWORK METHOD FOR PREDICTING THE STATE OF INFORMATION OBJECTS
Authors: Obukhov A. D.
Published: December 2021

The analysis and process of not only the current states of information objects, but also the prediction of future states with a certain time interval presents a major significance for adaptive information systems. This allows improving the quality and reliability of these systems functioning, reducing the delay in response to external influences, preparing for operations, and increasing the responsiveness and speed of the system. In order to solve this problem, the article proposes a neural network method for forecasting the state of information objects based on the application of machine learning technologies. A formalized algorithm for its implementation in the notation of set theory is presented. A distinctive characteristic of the designed method is the automatic determination of the optimal structure of the neural network, depending on the type of information object. The method also covers the possibility of using the complex of the previous states of the object to improve the forecast accuracy. Practical researches on approbation of the neural network method showed its efficiency and high accuracy. The following popular datasets were used as input data: Individual household electric power consumption, HAR (Human Activity Recognition) accelerometer, as well as gathered data on human relocation. LSTM (Long Short-Term Memory) neural network was applied to conduct the forecasts. The comparison of the developed method with a similar software solution DEvol (DeepEvolution) showed comparable or better indicators in terms of accuracy and time for the problem solution (1.7 times faster on average).
MANAGEMENT OF TESTS OF COMPLEX TECHNICAL SYSTEMS BASED ON A CONSISTENT RELIABILITY ASSESSMENT AND TAKING INTO ACCOUNT A PRIORI DATA ON THEIR ELEMENTS
Authors: Buryak Yu. I. , Skrynnikov A. A.
Published: December 2021

The article deals with the problem of reducing the volume of tests of complex systems by using a priori data on the reliability of their elements. At the preliminary stage, the a priori distribution of the probability of failure of the system as a whole is determined. To do this, the results of element tests are processed and the parameters of the a posteriori probability distribution of element failure are determined based on the Bayesian procedure. The type of distribution law (beta distribution) is chosen from the conjugacy condition. Statistical modeling of the system failure probability of a known structural-logical reliability scheme is performed for random values of the failure probabilities of each element, set in accordance with the obtained distribution law. The system failure probability distribution law is formed as a mixture of beta distributions; the advantage of this distribution law is a fairly high accuracy of the simulation data description and conjugacy to the binomial distribution. The parameters of a mixture of beta distributions are determined using the EM (Expectation-Maximization) algorithm. The quality of selection of the desired distribution density is checked using the nonparametric Kolmogorov criterion. When testing the system, after each experiment, the a posteriori density of the probability distribution is recalculated; it is represented as a mixture of beta distributions with a constant proportion of components. The parameters of each element of the mixture are easily determined by the results of the experiment. As a point Bayesian estimate, the average value calculated from the a posteriori distribution is taken, the confidence interval for a given confidence probability is found as the central interval. An example is given and the possibility of minimizing the number of tests is shown.
PROCESSING OF DATA FROM FIELD OBSERVATIONS OF WATER FLOW VELOCITY PROFILES IN A SHALLOW RESERVOIR BASED ON THE KALMAN FILTER
Authors: Atayan A. M. , Chistyakov A. E. , Nikitina A. V.
Published: December 2021

The paper is devoted to the numerical implementation of the Kalman filter algorithm for processing data from natural experiments obtained during expedition work to research the ecological state of the Azov Sea. Due to the use of various types of measuring devices placed on a research vessel, there is a problem of interference in the signal. To analyze the data of full-scale measurements of the profile of the three-dimensional velocity vector of the water environment’s movement in the Eastern part of the Sea of Azov at the qualitative and quantitative levels, sensor readings with a minimum amount of interference are necessary. In this paper, we selected the Kalman filter algorithm that allows us to obtain the minimum dispersion of the unbiased estimate of the dynamic system’s state. The Kalman filter is an algorithm that can be used to analyze measurements that include not only the desired measurements of the observed parameter or value, but also noises. Based on the full-scale velocity profiles measured by the ADCP probe at some points of the shallow water, a data filtering algorithm was constructed. A software module has been developed for solving the problem of filtering data of water flow velocities fields. The solution to the problem of constructing a filtration model is based on the two-stage Kalman algorithm. Estimates of the coefficients describing the error of the model and the measuring device are obtained. Natural measurements of the water flow velocity are used as input data for solving the filtration problem. Measurements were recorded at one second intervals every 10 centimeters. 128 measurements of each of the components of the velocity vector were performed in depth at the current time. The implementation of the Kalman filter algorithm for field measurements of the velocity field of the water flow of the Azov Sea was carried out using: the Python programming language, the PyCharm integrated development environment. PyCharm makes development as productive as possible with code completion and analysis features, instant errors highlighting, and quick fixes. With PyCharm, smart code updates are available with safe deletion and renaming, a extract method, an input variable, an inline variable or method, and other refactorings. Framework and programming language oriented refactorings will help you make any change within an entire project. Processing of natural measurements based on Kalman’s filtering makes it possible not only to refine the input data for the mathematical model problem of hydrodynamics, but also to significantly reduce the error of its solution.

Authors: Simankov V. S. , Dubenko Yu. V.
Published: December 2021

The system analysis of the hierarchical intelligent multi-agent system in general, as well as its main structural unit, the intelligent agent, its major subsystems identified. As part of the analysis of the computer vision subsystem, it was concluded that the considered sources have insufficiently worked out issues related to the processing of occlusions, with the automation of the process of reconstruction of three-dimensional scenes, with the implementation of the processing of an unstructured set of images. The structure of the block for the reconstruction of three-dimensional scenes is proposed, the implementation of which is aimed at eliminating the indicated problems characteristic of the machine vision subsystem. The analysis of the main methods of implementing unsupervised learning is carried out, based on the results of which it is concluded that it is advisable to use reinforcement learning when implementing systems of this type. Such types of reinforcement learning as hierarchical reinforcement learning and multi-agent reinforcement learning are considered. A method for segmentation of macro actions is proposed, based on the implementation of clustering by the method of label propagation, in which the number of transitions is formalized in the form of weight coefficients of edges.
APPROACH TO DATA BANKS PROCESSING IN CORPORATE INFORMATION SYSTEMS FOR DEFECTS LOCALIZIN
Authors: Mozhenkova E. V. , Paramonov A. I.
Published: December 2021

The paper considers issues of data migration from corporate information systems of clients for localizing defects on the developer’s side. The main revealed problem is the defects localization on the client side. As a solution, an approach to data banks processing is proposed. The approach is based on the defect data exchange method and the defect presentation model. The paper describes an information flows model of a corporate system in the context of the detected defects layer (data cast). The main task of data banks processing in defect localization is determined. It is the selection of data cast for a specified time period. A defect model is proposed in the form of a parameters set for data selection, which is built on the metadata concept. The model is defined as a tuple of data records from a set of interrelated entity tables for some time period. Thus, application of the proposed approach will automate the data migration process between client and developer systems and, in general, will increase the efficiency of corporate information systems support by reducing the processed and sent information. The results of a computer experiment showed that the data volume during the migration process significantly decreased. To approach will improve the efficiency of maintaining corporate systems by reducing the processed and transmitted information. Potentially, this model can be applied in the inverse problem – to migrate data from the developer’s side to the client. It is supposed to carry out processing on a database of any size and structure.
AUTOMATIC ARRHYTHMIA DETECTION BASED ON THE ANALYSIS OF ELECTROCARDIOGRAMS WITH DEEP LEARNING
Authors: Shchetinin E. Yu.
Published: December 2021

According to the World Health Organization, cardiovascular diseases (CVD) are one of the most common causes of death in the world. The most effective clinical method for visualizing the cardiac electrical activity is electrocardiography (ECG). Automated ECG analysis has been of great interest in the medical researches. The problem of automated detection of cardiac arrhythmias may be reduced to the ECG signals classification. To solve this task such methods were used as Hidden Markov Models (HMM), discrete wavelet transforms (DWT), support vector machine (SVM) etc. Now days, the deep learning models began to play the major role in solving this problem. In this paper, for the classification of ECG signals, a number of models of deep neural networks, including deep convolutional, recurrent based on short-term long memory have been developed and implemented. To improve the classification accuracy of individual classes of the studied data, the CNN-LSTM deep model was built, which combines convolutional and recurrent networks. In addition the following machine learning algorithms were used for ECG signals classification: support vector machine (SVM), decision trees (DT), random forest (RF) and extreme gradient boosting (XGB). To test the performance of the proposed models, MIT-BIH database was used, a freely available dataset that is widely used to evaluate the effectiveness of ECG signal classification algorithms. The results of a comparative analysis of various algorithms for the quality of classification for individual classes showed that machine learning algorithms classify classes with a large volume of samples well. For example, SVM and DT classify samples from class N and Q with an accuracy of 92 and 97%, respectively, while samples from classes S and F are classified with much worse accuracy of 63%. At the same time, analyzing and comparing the performance of various neural network models based on the obtained estimates of the classification accuracy, it can be argued that CNN LSTM model allows not only a high classification accuracy of 99.37%, but also high values of other indicators of classification quality, such as F1- metric, precision, and recall.The proposed algorithms for the automated detection of cardiac arrhythmias can be applied in biomedical applications that analyze the electrocardiogram and help physicians diagnose cardiac arrhythmias more accurately.

Authors: Rodzin S. I.
Published: December 2021

The authors propose a hyperheuristic bioinspired algorithm for selecting the most important classification features and assessing the classification accuracy. The algorithm is a modification of two approaches – bats echolocation bioheuristics and differential evolution. The k-nearest neighbors and decision tree classifiers were used in the experiments. The authors also assess the efficiency of the algorithm using reference datasets from the world library UCI (the University of California, Irvine). Based on the results of the experiments, the performance of the algorithm was compared with competing bioheuristics of bats, crows, gray wolves, a hybrid particle swarm algorithm, and gravitational search. We can say that the algorithm leads in the average and best values of the fitness function for most of the tested datasets, and is also statistically significant compared to competing algorithms according to the Wilcoxon T-test and the Friedman test.
METHOD FOR STEGANOGRAPHIC HIDE OF INFORMATION BASED ON CONTINUOUS WAVELET TRANSFORM
Authors: Variukhin V. A. , Levina A. B.
Published: December 2021

This article discusses continuous wavelet transform as a method of steganographic embedding of confidential information into an image. The main purpose of steganography is to hide information so that the possibility of data detection is minimized. This is done by hiding the message inside the container so that outsiders are not aware of the secret’s existence. Thus, the main principle of steganography is the principle of invisibility, which is also the basis of security when using these systems to transfer information. Steganography methods are divided into two large groups: spatial and frequency. The former visually degrade the image quality by directly changing the components (pixels). The latter interact with frequency characteristics, which has the best effect on the quality of the converted image. At this point in time, one of the most common frequency methods (discrete-cosine transform) is increasingly being replaced by a wavelet transform. This method of embedding confidential information is visually less noticeable to human vision, relative to those existing at a given time.The paper presents brief theoretical information on the wavelet transform, gives the characteristics of the Haar transform, presents images demonstrating the principle of the wavelet transform. The developed algorithm for steganography based on the wavelet transform is shown. The algorithm was implemented in the Matlab environment, as well as the analysis of the results obtained using the example of a test image. Conclusions, advantages of this method, as well as recommendations for further research in this area are given.
MORPHOLOGICAL IMAGE ANALYSIS BASED ON ATTRIBUTE AND RELATIONAL REPRESENTATIONS OF MOSAIC IMAGE MODELS
Authors: Vizilter Yu. V. , Vygolov O. V. , Zheltov S. Yu. , Morzhin A. V.
Published: December 2021

A unified scheme for morphological analysis based on attribute and relational representations of mosaic image models is proposed. We consider 4 main types of model representation: functional-attribute (2D feature map), functional-relational (4D relational map), structure-resource-attribute (an area list with resources and attributes), and structure-resource-relational (a graph, which nodes correspond to regions and edges – to relations and both having resource attributes). In this case, the forms of representation of the model are equivalent to each other, in the sense that they contain the same information, there is a one-to-one correspondence between them, and the formulas for the transition from one representation to another can be written out explicitly. In this scheme, the construction of specific morphological operator for some complete image model presumes the separation of this model into two parts: the guiding (modifying) part, which determines the transformation algorithm, and the guided (modifiable) part to be transformed. These two parts of the model can intersect, therefore cannot be called “variable” and “constant” components. As a basic sample, we consider the halftone Pyt’ev morphology. We explore the specifics of different-sort models, introduce the mutual models and propose different tools for creation of model-based morphological operators. Further, various other morphological systems can be described and explored using the proposed generalized approach.
INTERACTIVE APPLICATION DEVELOPMENT BASED ON THE JOINT USE OF THE HASKELL FUNCTIONAL PROGRAMMING LANGUAGE AND Qt FRAMEWORK
Authors: Konyuhova O. V. , Kravtsova E. A. , Uzharinskiy A. Yu.
Published: December 2021

The Haskell language allows you to efficiently implement computational algorithms. Higher-order functions, composition of functions, lazy calculations allow you to create functional programs with a clear structure that most fully reflect the logic of the algorithm being implemented. This allows you to get programs that are more compact and more flexible to make changes. Also, the use of pure functions allows you to avoid errors associated with the influence of the “side effect”. The I / O operations required for user interaction use special constructs and functions with a “side effect”, which violates the functional purity of the Haskell language. The approach considered in the article involves the allocation of two parts in an interactive application: interface (front-end) and computing (back-end), interacting with each other by exchanging parameters. The interface part of the application organizes the interaction with the user through the graphical user interface, and the computational part provides the algorithm implementation. To implement front-end is proposed to use the Qt Creator framework with C++ language, and to implement the back-end – the Haskell language. Using a shared address space (files) for data exchange minimizes the impact of the “outside world” on the Haskell program. We also consider a possible way of the software implementation of this approach and example of its applying to develop an application for solve the k-shortest path problem in a graph.
IMAGE SHAPE COMPARISON IN MOSAIC DIFFUSION MORPHOLOGIES
Authors: Vizilter Yu. V. , Vygolov O. V. , Zheltov S. Yu.
Published: December 2021

In this paper, developing the early proposed unified approach to the representation of morphological models, we show that since morphological models in the attribute representation have the same mathematical form as images, the morphological models themselves can be the subject of morphological analysis and can be directly compared in form with using morphological operators. In this case, the previously introduced formalism of mosaic diffusion morphology is used.In the framework of mosaic diffusion morphology, two alternative descriptions of the projection of the image on the form are considered, which are based on a clear model and a fuzzy model of the form respectively. It is shown that the projection operator in the second case is a one-sorted diffuse operator that makes direct comparision of model to model instead of image to model. In this case, a fuzzy mosaic model appears in this scheme as a projection of a clear mosaic model onto another clear mosaic model. Based on this shape-to-shape projection idea, we propose the new version of Pytiev morphology tools for shape comparison: the morphological shape difference map, the morphological quasi-distance between shapes, as well as the Morphological Shape Correlation Coefficient (MSCC). We show that MSCC from the resource parameters of the reciprocal model has exactly the same formula as the standard effective morphological correlation coefficient proposed earlier based on statistical averaging of projected images.
ALGORITHMIC METHOD OF AUTONOMOUS CORRECTION MEASUREMENT ERRORS IN SYSTEMS AUTOMATIC CONTROL AND REGULATION
Authors: Kikin I. S.
Published: December 2021

A method of autonomous a posteriori estimation of control target’s state coordinates is demonstrated. The method’s accuracy does not depend on automatic control system sensors errors. An algorithmic implementation of the method is proposed – an algorithm for processing the array of data on the control target observed inputs and outputs, obtained by passive information accumulation during the observation interval of the control target normal functioning. At the final stage of the estimation algorithm, the implemented control process is simulated with complete a priori information about the conditions for its implementation (simulation estimation method). The algorithm execution time should be negligible in relation to the duration of the observation interval (instantaneous a posteriori estimation of the control target’s state). The proposed method allows to cyclically correct instrumental errors of automatic control and regulation systems without using external sources of information.

Published: December 2021

In this paper, the geometric theory of multidimensional interpolation was further developed in terms of modeling and using adaptive curves passing through predetermined points. A feature of the proposed approach to modeling curved lines is the ability to adapt to any initial data for high-quality interpolation, which excludes unplanned oscillations, due to the uneven distribution of parameter values, the source of which are the initial data. This is the improvement of the previously proposed method for constructing and analytically describing arcs of algebraic curves passing through predetermined points, obtained on the basis of Bezier curves, which are compiled taking into account the expansion coefficients of the Newton binomial. The paper gives an example of using adaptive algebraic curves passing through predetermined points for geometric modeling of the stress-strain state of membrane coatings cylindrical shells using two-dimensional interpolation. The given example an illustrative showed the advantages of the proposed adaptation of algebraic curves passing through predetermined points and obtained on the basis of Bezier curves for geometric modeling of multifactor processes and phenomena. The use of such adaptation allows not only to avoid unplanned oscillations, but also self-intersection of geometric objects when generalized to a multidimensional space. Adaptive algebraic curves can also be effectively used as formative elements for constructing geometric objects of multidimensional space, both as guide lines and as generatrix’s.

The present issue of Studies in Second Language Learning and Teaching is the last in the 2021 volume and concludes the eleventh year of the existence of the journal. Looking back, it has been an exceptionally good year for SSLLT. First, we have been receiving a constantly increasing number of submissions and, what is of paramount importance for any journal, most of these submissions have been of very high quality. Second, we are very happy with the scope and quality of the papers that have been published, including those comprising the special issue on teaching English reading and writing to young learners, which was guest-edited by Barry Lee Reynolds and Mark Feng Teng. Third, and perhaps most importantly, not only has SSLLT been finally indexed in the Web od Science, but it is also listed among the 20 best journals in linguistics (18/193), with the impact factor of 3.036 (Q1) (JCR). Achieving this status has been a long and arduous process but at the same time an extremely rewarding journey. Obviously, this undeniable success would not have been possible without all of those who have lent their support to the development of SSLLT from the get-go. My sincere thanks go to Associate Editors, all the guest editors of special issues, members of the Editorial Board, the many hundreds of reviewers and, first and foremost, to all the amazing authors who have chosen SSLLT as a venue for their work. I can assure all of you that we will not be resting on our laurels and will do everything in our power to keep up the good work to further enhance the position of SSLLT in the field. We are also hoping to be able to celebrate its success with a face-to-face conference to be held in Kalisz, Poland in October 2022. We are currently working on the call for papers and we are planning to send it out in the next month or so.
Accuracy order in L2 grammatical morphemes: Corpus evidence from different proficiency levels of Turkish learners of English
Authors: Akbaş Erdem , Ölçü-Dinçer Zeynep
Published: December 2021

The present study empirically scrutinizes the fixed natural order of grammatical morphemes relying on a manual analysis of an EFL learner corpus. Specifically, we test whether the accuracy order of L2 grammatical morphemes in the case of L1 Turkish speakers of English deviates from Krashen’s (1977) natural order and whether proficiency levels play a role in the order of acquisition of these morphemes. With this in mind, we focus on the (in)accuracy of nine English grammatical morphemes with 2883 cases manually tagged by the UAM Corpus Tool in the written exam scripts of Turkish learners of English. The results based on target-like use scores provide evidence for deviation from what is widely believed to be a set order of acquisition of these grammatical morphemes by second language learners. In light of such findings, we challenge the view that the internally driven processes of mastering grammatical morphemes in English for interlanguage users are largely independent of their L1. Regardless of L2 grammar proficiency in our data, the observed accuracy of some morphemes ranked low in comparison with the so-called natural order. These grammatical morphemes were almost exclusively non-existent features in participants’ mother tongue (e.g., third person singular –s, articles and the irregular past tense forms), thus suggesting the influence of L1 in this respect.
Professionalization of non-medical support of women in perinatal period: the significance of the doula profession
Authors: Stępkowska Justyna , Królak Anna , Stępkowska Katarzyna
Published: December 2021

Wprowadzenie:Doula (gr. „kobieta, która służy”) to osoba przeszkolona do udzielania kobiecie i jej rodzinie wsparcia emocjonalnego, fizycznego i informacyjnego w czasie ciąży,porodu i połogu.

Cel:Celem pracy jest próba analizy roli i zadań douli na płaszczyźnie zróżnicowanych potrzeb kobiet rodzących z uwzględnieniem wyników wstępnych badań dotyczących opinii i doświadczeń polskich kobiet na temat wsparcia douli w okresie okołoporodowym.

Metody: Przeprowadzone badanie miało charakter wstępny. Badaniem ilościowym objęto 526 kobiet z wywiadem położniczym, w wieku od 18 do 50 lat. Próba została podzielona na grupę badaną (kobiety, które kiedykolwiek skorzystały z usług douli) N=62 i grupę kontrolną (kobiety, które nigdy nie korzystały z asysty douli) N=464. Dane zostały zebrane anonimowo, za pomocą autorskiego kwestionariusza w formie badania on-line. Dobór próby celowy. Wyniki poddano analizie statystycznej. Obliczeniawykonano w programie PQStat (wersja 1.6.6).

Wyniki: Zawód douli i możliwość skorzystania z jej wsparcia w okresie okołoporodowym nie są szeroko rozpoznawane wśród badanych kobiet w Polsce. Wyniki wskazują na konieczność lepszego wsparcia rodzącej, zwłaszcza w zakresie potrzeb informacyjnych, emocjonalnych oraz wsparcia w zakresie niefarmakologicznych metod łagodzenia bólu porodowego. W opinii badanych kobiet, które korzystały z asysty douli, jej wsparcie miało korzystny wpływ na przebieg okresu okołoporodowego.

Wnioski:Wydaje się, że wsparcie douli jako dodatkowa forma opieki na oddziałach położniczych powinna być traktowana bardziej otwarcie. Niezbędna jest również promocja i popularyzacja alternatywnych form wsparcia prenatalnego i poporodowego poprzez kampanie edukacyjne i promocję dedykowanych usług opiekuńczych i wspierających, takich jak usługi douli, w celu zapewnienia lepszej opieki dla kobiet w okresie około porodowym i redukcji czynników stresogennych. Przeprowadzone badania wskazują na potrzebę popularyzowania informacji o istnieniu zawodu douli oraz rozpowszechniania wiedzy o zadaniach i roli douli.
Kontrowersja animacji poczęciowej: spór nierozwiązywalny? Krytyczna ocena wybranych koncepcji animacji embrionu ludzkiego

Fenomen poronienia klinicznego wzbudza coraz większe zainteresowanie badaczy z dyscyplin pozamedycznych. Choć nadal dostrzegalna jest znacząca dysproporcja pomiędzy obszerną literaturą traktującą o poronieniu spontanicznym z perspektywy medycznej w porównaniu do wzrastających liczebnie studiów prowadzonych w zakresie nauk społecznych i filozoficznych, to sukcesywnie postępuje proces zmiany orientacji badawczej wczesnych strat prokreacyjnych. Dominujące dotychczas jednostronne podejście biomedyczne ustępujące miejsca holistycznym ujęciom aksjomedycznym. Niniejsze studium wpisuje się w aksjomedyczny model poronienia klinicznego. Jego celem jest pogłębiona analiza czterech kluczowych kontekstów straty prokreacyjnej występującej na początkowych etapach rozwoju prenatalnego ‒ antropologicznego, relacyjnego (przywiązania rodzicielskiego), psychologicznego i pomocowego. W rezultacie prowadzonych badań dochodzimy do wniosku, iż główną dominantą charakterystyk poronienia klinicznego jako zdarzenia tanatycznego jest płaszczyzna rozstrzygnięć antropologicznych statusu płodu i jego implikacji etycznych.

Cnoty teologalne (wiara, nadzieja, miłość) uzdalniają władze człowieka do uczestnictwa w naturze Bożej, do życia w jedności z Trójcą Świętą. Ukierunkowują one życie chrześcijańskie do pełnej komunii z Bogiem. Ich początkiem, motywem i przedmiotem jest Bóg, poznawany przez wiarę, w którym pokładamy nadzieję i którego miłujemy dla Niego samego. Cnoty teologalne kształtują, pobudzają i charakteryzują działanie moralne chrześcijanina – życie teologalne. Są wszczepione przez Boga w dusze wiernych, by uzdolnić ich do działania jako dzieci Boże i do zasługiwania na życie wieczne. Odsłaniają cel życia ludzkiego – Bóg powołuje nas do swojego własnego szczęścia. Cnoty teologalne stanowią rękojmię obecności i działania Ducha Świętego we władzach człowieka. Życie moralne chrześcijan jest podtrzymywane przez dary Ducha Świętego. Są one trwałymi dyspozycjami, które czynią człowieka uległym, by iść za poruszeniami Ducha Świętego.
Revisión taxonómica de la ictiología marina de Galicia: Clase Actinopteri (Orden Acipenseriformes al Orden Scorpaeniformes)
Authors: Bañón Díaz Rafael , Maño Toño
Published: December 2021

En este trabajo se realiza una revisión taxonómica de los peces óseos de Galicia (Clase Actinopteri) del Orden Acipenseriformes al Orden Scorpaeniformes, a través de los distintos tratados y publicaciones ictiológicas publicadas a lo largo de la historia. Se listan un total de 219 especies, de las cuales ocho se consideran dudosas, al no estar su presencia suficientemente demostrada o porque existen dudas sobre su estatus taxonómico. Una revisión de la bibliografía y nomenclatura científica nos ha permitido citar nuevas especies para Galicia y reasignar antiguas denominaciones a nuevas especies, subsanando errores de identificación de otros autores. Esta revisión permite además conocer la primera cita para cada especie en Galicia y establecer una cronología precisa del conocimiento taxonómico histórico de estos grupos de peces.

En este trabajo se realiza una revisión taxonómica de los peces óseos de Galicia (Clase Actinopteri) del Orden Trachiniformes al Orden Tetraodontiformes, a través de los distintos tratados y publicaciones ictiológicas publicadas a lo largo de la historia. Se listan un total de 188 especies, de las cuales 5 se consideran dudosas, al no estar su presencia suficientemente demostrada. Una revisión de la bibliografía y nomenclatura científica nos ha permitido citar nuevas especies para Galicia y reasignar antiguas denominaciones a nuevas especies, subsanando errores de identificación de otros autores. El orden Perciformes, con 145 especies, es el más numeroso de los peces de Galicia. A este orden pertenecen especies de alto interés comercial como el jurel Trachurus trachurus y la caballa Scomber scombrus. El listado también incluye también los primeros registros para Galicia de especies de carácter tropical desplazadas hacia el norte debido al cambio climático a lo largo de estas últimas décadas. Algunas de estas especies son el jurelo azul Caranx crysos, el pez globo Lagocephalus laevigatus y el mero tropical Epinephelus aeneus.

Se presenta el primer estudio de mapa de riesgos laborales psicosociales de la Comunidad de Madrid. El objetivo fundamental es situar y describir la presencia e impacto de los riesgos laborales psicosociales en población trabajadora de Madrid. Para ello, se combinaron metodologías cualitativas como estrategias de análisis documental, grupos de discusión o entrevistas a informantes clave junto con metodologías cuantitativas de recogida de datos y procedimientos muestrales. En la novedad de esta investigación por sus características y objeto de estudio, los principales resultados señalan la emergencia de un mercado laboral precario, fraccionado en el que se evidencian de manera particular riesgos laborales como la violencia y la inseguridad contractual. Tales riesgos transforman y cambian aquellos más tradicionales, estableciéndose un escenario complejo para la prevención y la gestión en esta materia. En suma, se hace necesario adaptar las medidas y evaluaciones de Prevención de Riesgos Laborales (PRL), y más concretamente, aquellas dirigidas a riesgos laborales psicosociales, a este nuevo contexto, a la par que desarrollar nuevos modelos de intervención y prevención propiamente dicha.
When age becomes a plus: Seniors and Cognitive Reserve
Authors: Rimassa Carla , Taramasco Carla
Published: December 2021

Cognitive Reserve alludes to gain, resistance, plasticity and is the functional correlative of neuroplasticity and a potential protection factor, which could explain why some patients may show the same pathology but quite different clinical manifestations. Among the activities considered as promoters are studies, work, physical and social activities. Although there are surveys or tables that seek to measure these factors and reflect this reserve in an index, this can be a quite reductionist strategy. Given the increasing ageing of the population, added to the active elders paradigm, programs addressed to seniors are carried out; it is important to consider that gains are accumulative and dynamism must be promoted from earlier ages. The sample for this work consisted of 30 seniors (60–87years) from the Region of Valparaíso, Chile. The CRIq was applied to the participants to measure the CR index and no differences were found between men and women. The purpose of this work is to describe the activities that promote reserve, carried out from 18 years onwards by 30 autonomous and cognitively competent seniors. It is held that it is not the type of activity that matters, but rather the frequency and the length of the execution period that turns into advantages for the persons. The data submitted reveal that seniors never failed to frequently execute some of the activities. That is, they had the habit of being active along their whole lives. This mechanism could be considered as a kind of dynamo where the greater input of promoting activities would make possible better conditions of the nervous system, but it does not have an easy storage as it is in continuous use. For this reason, gains depend on the active habit of execution, its early start, diversity of activities and permanence during the whole life span.
On the structure of some non-periodic groups whose subgroups of infinite special rank are transitively normal

Розглядається задача про рух високов’язкої рідини у вузькому каналі з підігрівом, який моделює процес екструдування полімерів для тривимірного друку. Важливим елементом для цього класу задач є підбір параметрів руху полімерної маси та теплообміну з метою сталого формування виробу. Він полягає в тому, щоб трохи перегріту масу подати до відповідного місця, де вона швидко застигне, в результаті чого буде стійко зберігатися форма друкованого виробу. Як робоче середовище використовуються відповідні полімери, які мають необхідні властивості. У задачі, що розглядається, для розкриття фізичних особливостей процесу використовується ньютонівська рідина, яка за своїми властивостями є близькою до поліетилентерефталату (ПЕТФ), який також застосовується в технології тривимірного друку. Задачу про рух і теплообмін сформульовано в рамках теорії моделі вузького каналу з урахуванням дисипації механічної енергії. Для високов’язких рідин, навіть незважаючи на малі швидкості, урахування дисипативних членів є необхідним, оскільки великі градієнти швидкостей можуть призводити до великої величини дисипації і, відповідно, до значного зростання температури. Ця особливість виявилася надзвичайно важливою саме для такого класу задач. Для більш яскравого подання розв’язку крім однієї рідини, близької до ПЕТФ, розглянуто рух і нагрів рідини, в’язкість якої у 10 разів менша за в’язкість полімеру. Розв’язання було проведено методом смуг, в яких температура і, відповідно, в’язкість, що залежить від неї, приймалися незалежними від поперечної координати. Це дозволило використовувати аналітичну залежність для швидкостей у кожній смузі, що зробило метод напіваналітичним та полегшило розв’язання задачі. Результати, отримані чисельно, вказують на те, що в робочому інтервалі формування (приблизно 0,1 м/с та 0,5 м/с), дисипація дійсно значно впливає на процес. Так, для умовно малов’язкої рідини перегрів її в кінці апарату виявляється істотним, але може бути знятий за допомогою додаткового обдування. Для високов’язкої рідини це зробити практично неможливо, тобто така рідина не може використовуватися в апараті з розглянутими геометричними розмірами. Отже, математичне моделювання досліджуваного процесу дає можливість проводити розрахунки параметрів течії та визначати необхідні умови і, відповідно, властивості рідини для стійкого тривимірного друкування.
