Inertial-Measurement-Unit-Based Novel Human Activity Recognition Algorithm Using Conformer
Authors: Kim Yeon-Wook , Cho Woo-Hyeong , Kim Kyu-Sung , Lee Sangmin
Published: May 2022

Inertial-measurement-unit (IMU)-based human activity recognition (HAR) studies have improved their performance owing to the latest classification model. In this study, the conformer, which is a state-of-the-art (SOTA) model in the field of speech recognition, is introduced in HAR to improve the performance of the transformer-based HAR model. The transformer model has a multi-head self-attention structure that can extract temporal dependency well, similar to the recurrent neural network (RNN) series while having higher computational efficiency than the RNN series. However, recent HAR studies have shown good performance by combining an RNN-series and convolutional neural network (CNN) model. Therefore, the performance of the transformer-based HAR study can be improved by adding a CNN layer that extracts local features well. The model that improved these points is the conformer-based-model model. To evaluate the proposed model, WISDM, UCI-HAR, and PAMAP2 datasets were used. A synthetic minority oversampling technique was used for the data augmentation algorithm to improve the dataset. From the experiment, the conformer-based HAR model showed better performance than baseline models: the transformer-based-model and the 1D-CNN HAR models. Moreover, the performance of the proposed algorithm was superior to that of algorithms proposed in recent similar studies which do not use RNN-series.
Deep Learning-Based Channel Estimation for mmWave Massive MIMO Systems in Mixed-ADC Architecture
Authors: Zhang Rui , Tan Weiqiang , Nie Wenliang , Wu Xianda , Liu Ting
Published: May 2022

Millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) systems can significantly reduce the number of radio frequency (RF) chains by using lens antenna arrays, because it is usually the case that the number of RF chains is often much smaller than the number of antennas, so channel estimation becomes very challenging in practical wireless communication. In this paper, we investigated channel estimation for mmWave massive MIMO system with lens antenna array, in which we use a mixed (low/high) resolution analog-to-digital converter (ADC) architecture to trade-off the power consumption and performance of the system. Specifically, most antennas are equipped with low-resolution ADC and the rest of the antennas use high-resolution ADC. By utilizing the sparsity of the mmWave channel, the beamspace channel estimation can be expressed as a sparse signal recovery problem, and the channel can be recovered by the algorithm based on compressed sensing. We compare the traditional channel estimation scheme with the deep learning channel-estimation scheme, which has a better advantage, such as that the estimation scheme based on deep neural network is significantly better than the traditional channel-estimation algorithm.
Nonlinear Predictive Motion Control for Autonomous Mobile Robots Considering Active Fault-Tolerant Control and Regenerative Braking
Authors: Hang Peng , Lou Baichuan , Lv Chen
Published: May 2022

To further advance the performance and safety of autonomous mobile robots (AMRs), an integrated chassis control framework is proposed. In the longitudinal motion control module, a velocity-tracking controller was designed with the integrated feedforward and feedback control algorithm. Besides, the nonlinear model predictive control (NMPC) method was applied to the four-wheel steering (4WS) path-tracking controller design. To deal with the failure of key actuators, an active fault-tolerant control (AFTC) algorithm was designed by reallocating the driving or braking torques of the remaining normal actuators, and the weighted least squares (WLS) method was used for torque reallocation. The simulation results show that AMRs can advance driving stability and braking safety in the braking failure condition with the utilization of AFTC and recapture the braking energy during decelerations.
Preventive measures of Rostrud: features of the exercise of powers to prevent violations of labor rights
Authors:   Kuban State Agrarian University, Krasnodar, Sapfirova A.A.
Published: May 2022

The shift in emphasis in the activities of Rostrud from the “sanction model” to the priority of preventive measures in the labor sphere is due to changes in the legislation on the implementation of control (supervisory) functions by state bodies. The article analyzes the mandatory preventive measures established for Rostrud and the additional preventive measures proposed by the author. As a result of the study, the following conclusions are drawn. First, informing is proposed to be considered from a broad and narrow perspective. Secondly, a distinctive feature of a preventive visit is not only the obligation of the state labor inspector to notify the employer of its conduct, but also the employer's right to refuse a preventive visit, except for mandatory cases. Thirdly, it is important to establish the obligation to conclude agreements on interaction between state inspectorates in the constituent entities of the Russian Federation and the MFC on informing and consulting. Fourth, it is proposed to consolidate the need for Rostrud to implement voluntary promising preventive measures: self-examination and incentives for conscientiousness. Fifthly, the goal of all preventive measures is defined.

El Acuerdo de Asociación entre la Unión Europea y Centroamérica: un potencial por explotar
Authors: Caldentey Pedro
Published: May 2022

El caso del acuerdo de asociación (AA) firmado en 2013 entre la Unión Europea (UE) y Centroamérica es muy relevante en el marco de las relaciones entre la UE y América Latina. Es el primer acuerdo birregional y se apoya en los antecedentes del Proceso de San José en el marco de los Acuerdos de Esquipulas, un caso de éxito sobre el impacto positivo de la UE en las relaciones internacionales. Este documento analiza el desarrollo del pilar comercial y las dificultades para desarrollar los pilares del diálogo político y cooperación, pendientes de ratificación. Los resultados preliminares del acuerdo son positivos, pero de baja intensidad para las dos regiones. No han respondido a las expectativas sobre la incidencia de la UE para apoyar el desarrollo centroamericano y no han generado incentivos significativos para mejorar el protagonismo de Centroamérica entre los Estados miembros de la UE. Recuperar los mecanismos de diálogo político previos al acuerdo entre las dos regiones, más informales pero más dinámicos, parece condición indispensable para que el acuerdo desarrolle su potencial.
County-Level Dialysis Facility Supply and Distance Traveled to Facilities among Incident Kidney Failure Patients
Authors: Velázquez Alexis F. , Thorsness Rebecca , Trivedi Amal N. , Nguyen Kevin H.
Published: May 2022

Key Points

The number of county-level dialysis facilities has increased between 2012 and 2019.

Patients in counties with no dialysis facilities traveled further to start treatment than those in counties with three or more facilities.

Background

The availability of dialysis facilities and distance traveled to receive care can impact health outcomes for patients with newly onset kidney failure. We examined recent changes in county-level number of dialysis facilities between 2012 and 2019 and assessed the association between county-level dialysis facility supply and the distance incident kidney failure patients travel to receive care.

Methods

We conducted a cross-sectional study of 828,427 adult patients initiating in-center hemodialysis for incident kidney failure between January 1, 2012, and December 31, 2019. We calculated the annual county-level number of dialysis facilities, and counties were categorized as having zero, one, two, or three or more dialysis facilities at the time of treatment initiation. We then measured the distance traveled between a patient’s home address and dialysis facility at treatment initiation (in miles) and evaluated the association between county-level number of dialysis facilities and distance traveled to initiate treatment.

Results

The average annual county-level number of facilities increased from 1.8 to 2.3 between 2012 and 2019. In our study period, 5% of incident adult kidney failure patients resided in a county that had zero dialysis facilities between 2012 and 2019. Compared with counties with three or more dialysis facilities, patients living in counties with no facilities in our study period traveled 14.3 miles (95% CI, 13.4 to 15.2) further for treatment.

Conclusions

Kidney failure patients in counties that had no dialysis facilities traveled further, limiting their access to dialysis. Counties with no dialysis facilities at the end of the study period were more rural and had higher poverty than other counties.

Dark-field ultrasonic imaging method using mode-converted longitudinal evanescent field
Authors: Oyabu Yota , Ohara Yoshikazu , Tsuji Toshihiro , Mihara Tsuyoshi
Published: May 2022

We propose a dark-field evanescent imaging method to visualize surface/subsurface micro defects with a high signal-to-noise ratio (SNR). This method utilizes the mode-converted longitudinal evanescent field (MCLEF) generated at defects by the incidence of a shear (S) wave. When an incident S wave only has the in-plane displacement on the top surface of a specimen, the 2D scan of a laser Doppler vibrometer, that can only measure out-of-plane displacements, can selectively probe the MCLEF with out-of-plane displacements. Note that the MCLEF can be generated even at a defect that is much smaller than the diffraction limit. In this paper, after describing the principle of the proposed method, we prove the concept in a specimen with a hole by finite element (FE) simulation and experiments. Further FE simulations demonstrate its super-resolution imaging capability for holes of different sizes and higher SNR than a conventional method for various defect geometries.

Authors: Ozaki Ryotaro , Nakahiro Keita
Published: May 2022

Berreman’s 4 × 4 matrix method is a standard method for the analysis of the optical properties of chiral liquid crystals such as cholesteric and ferroelectric liquid crystals. This method has been widely used to calculate transmission and reflection spectra and the density of states of chiral liquid crystals. A spatial profile of the electric field in a propagation medium is also important for fundamental research and development of optical devices, but electric field analysis by the 4 × 4 matrix method has not yet been established. We describe the calculation method of internal electric fields in liquid crystals by the 4 × 4 matrix method.

Published: May 2022

We experimentally evaluate the tolerance of a repeater laser (RL) method, which generates a reference wave using a phase-locked laser. The tolerance to the optical power variation of a plane wave component in a split object wave is limited by the dynamic range of an imager to record holograms in a conventional method, whereas it is limited by that of a photodetector for phase-locking in the RL method. The RL method using a commercial imager and photodetector achieved constant high measurement accuracy under the varying range of 50 dB and 100 times higher tolerance than the conventional method.

Polarimetric Microwave Sensor for Angular Speed Measurement
Authors: Mustapha Ademola , Rahman Mohammed Saif ur , Abou-Khousa Mohamed A.
Published: May 2022

This paper presents a design methodology and
prototyping of an angular speed sensor based on microwave polarimetry. The
detection mechanism relies on the transmission response of a dual-polarized
circular aperture irradiating an array of regularly spaced copper traces. The
generated response is a regular pulse train defined by the location of a copper
trace with reference to the center of the circular aperture. For speed
measurement, the response was acquired within a 10s duration with the circular
aperture response effectively sampled at 100 Hz. The acquired response was
analyzed in the frequency domain using Fast Fourier Transform (FFT) and the
rotor speed was obtained from the frequency spectrum of the acquired pulse
train. The detection system can detect
speeds as low as 0.4 RPM with an upper limit of 5000 RPM limited by the maximum
sampling rate of the acquisition system. With the adoption of the FFT technique
for speed estimation, the proposed angular speed measurement system can
instantaneously detect angular speed with a maximum absolute estimation error
of 0.0625 RPM within the 10 s acquisition time. The rotor occupies an area of
84.64 cm2.
Using Deep Learning Models to Predict Prosthetic Ankle Torque
Authors: Prasanna Christopher , Realmuto Jonathan , Anderson Anthony , Rombokas Eric , Klute Glenn K.
Published: May 2022

Inverse dynamics from motion capture is the most common technique for acquiring biomechanical kinetic data. However, this method is time-intensive, limited to a gait laboratory setting, and requires a large array of reflective markers to be attached to the body. A practical alternative must be developed to provide biomechanical information to high-bandwidth prosthesis control systems to enable predictive controllers. In this study, we applied deep learning to build dynamical system models capable of accurately estimating and predicting prosthetic ankle torque from inverse dynamics using only six input signals. We performed a hyperparameter optimization protocol that automatically selected the model architectures and learning parameters that resulted in the most accurate predictions. We show that the trained deep neural networks predict ankle torques one sample into the future with an average RMSE of 0.04±0.02 Nm/kg, corresponding to 2.9±1.6% of the ankle torque’s dynamic range. Comparatively, a manually-derived analytical regression model predicted ankle torques with a RMSE of 0.35±0.53 Nm/kg, corresponding to 26.6±40.9% of the ankle torque’s dynamic range. In addition, the deep neural networks predicted ankle torque values half a gait cycle into the future with an average drop in performance of 1.7% of the ankle torque’s dynamic range. This application of deep learning provides an avenue towards the development of predictive control systems for powered limbs aimed at optimizing prosthetic ankle torque. 
Analytical Models of Stochastic Scattering Loss for TM and TE Modes in Dielectric Waveguides Exhibiting Exponential Surface Roughness, and a Validation Methodology in 3D FDTD
Authors: Guiana Brian , Zadehgol Ata
Published: May 2022

The dielectric slab waveguide (DSW) has been the subject of much analysis in the past decades, with many important applications in high-speed high-bandwidth electromagnetic propagation; however, nearly all analysis of the DSW's stochastic propagation loss $\alpha$ (dB/cm), associated with random surface roughness of its sidewalls, has revolved around the transverse-electric (TE) mode of operation.

This work derives analytical expressions for $\alpha$ in the transverse-magnetic (TM) mode, and correlates it against numerical experiments in the method of finite-difference time-domain (FDTD) in both two-dimensional (2D) and three-dimensional (3D) space. In this work, we introduce the novel \textit{singular effective impedance} (SEI) formulation for normalization of the TM mode $\alpha$ and verify its accuracy through FDTD which shows near 0\% mean-error in both TM and TE modes. We perform several stochastic numerical experiments in 3D FDTD, where the DSW's width is set to be much larger than its height, and show that $\alpha$ correlates quite well against the proposed 2D analytical model and 2D FDTD. Finally, analysis of FDTD-computed data reveals that existing analytical models of $\alpha$ may be missing higher-order interaction terms involving correlation length $L_c$ (m) of the surface roughness.
Skew Filtering for Online State Estimation and Control
Authors: DOGRU OGUZHAN , Chiplunkar Ranjith , Huang Biao
Published: May 2022

Process optimization and control can become challenging when the measurements are affected by irregular noise. Classical approaches utilize Gaussian method like Kalman filtering to alleviate the sensory noise. However, many industries involve skewed noise in their processes. While the closed skew normal (CSN) distribution generalizes a Gaussian distribution with additional parameters, its dimension increases during recursive estimation, making it impractical. Even though there exist some techniques for the solution, they are typically either too complicated or inaccurate for the higher dimensional problems. This study proposes a novel online optimization scheme to reduce the dimensionality of a CSN distribution while considering the properties of the complete empirical distribution. Since the objective function used during the optimization step considers the geometry of the metric space, the proposed scheme achieves the higher accuracy without sacrificing computational efficiency. After finding the reliable combination of objective function and optimizer, the proposed filter is applied to two real-time pilot-scale experiments. The results indicate that it is beneficial for recursive state estimation in the presence of skewed noise.

In this paper, we provide a comprehensive and systematic review and analysis of the recent progress in DL methods for omnidirectional vision. There are some previous surveys in the literature. However, some of them are focused on the specific vision tasks, especially room layout reconstruction, 3D scene geometry recovery. Moreover, some provide limited reviews of omnidirectional video streaming methods. Unlike existing surveys, this paper highlights the importance of deep learning and probe the recent advances for omnidirectional vision, both methodically and comprehensively. To the best of our knowledge, this is the first survey to comprehensively review and analyze the DL methods for omnidirectional vision.

The main contributions of this paper to the community are five folds:

(I) We comprehensively review and analyze the DL methods for omnidirectional vision, including the omnidirectional imaging principle, representation learning, datasets, a taxonomy, and applications, to highlight the differences and difficulties with the 2D planner image data.

(II) We conduct an analytical study of recent trends of DL for omnidirectional vision, both hierarchically and structurally. Moreover, we offer insights into the discussion and challenge of each category.

(III) We summarize the latest novel learning strategies and potential applications for omnidirectional vision.

(I) We provide insightful discussions of the challenges and open problems yet to be solved and propose the potential future directions to spur more in-depth research by the community.

(II) We create an open-source repository that provides a taxonomy of all the mentioned works and code links, and hope it can shed light on future research.

The organization of this paper is structured as follows. In Sec.2, we introduce the imaging principle of ODI, convolution methods for omnidirectional vision, and some representative datasets. In Sec.3, we review and analyze the existing DL approaches for various tasks and provide taxonomies to categorize the relevant papers. Sec.4 covers novel learning paradigms for the tasks in omnidirectional vision, e.g., unsupervised learning, transfer learning, and reinforcement learning. Sec.5 then scrutinizes the applications, followed by Sec. 6, where we discuss open problems and future directions. Finally, we conclude this paper in Sec. 7. Furthermore, we summarize most, if not all but representative, works (over 200 papers) in the last five years, which were published in the top-tier conferences and journals in computer vision/graphics and machine learning.

Introduction: Patients frequently suffer from shivering following surgery. The shivering experienced by the patients may be a natural, thermal regulatory response to central hypothermia or as a result of the release of cytokines during the surgical process. This is unpleasant and occurs following surgery in 30-65% of patients who have received general anesthetics. Shivering increases the muscular activity, O2 consumption, CO2 production and may result in hypoxaemia, hypercarbia and lactic acidosis. It is not only uncomfortable but also cold sensation which is even worse feeling than pain sensation. Objective: To assess the Comparison the efficacy of ketamine on the patients undergoing elective surgery for prevention of postoperative shivering. Material & Methods: In this prospective study was conduct at the dept. of Anaesthesia, Shaheed Tajuddin Ahmad Medical College Hospital, Gazipur, Bangladesh from January to June-2021. Fifty (50) patients included in our study. The inclusion criteria were women aged between 30-65 years and ASA-PS classes I and II. Patients preoperative period were fasted at least 6 hrs and on arrival at OT I/V line was inserted; pulse, BP respiratory rate and SpO2 were recorded. Results: In our study fifty two (52) patients demographic data concerning the patient age, weight as well as duration of anaesthesia and type of surgery were comparable in two groups which are fairly matched. In preoperative situation in Group A mean pulse rate was 79 ±2.4, in Group B 82 ±1.5, mean anterial pressure 92.71±1.05 (Group A), 94.01±1.14 (Group B), SpO2 99±0.56 Group A, 98 ±0.26 (Group B) which showed no significant difference between the groups. In the postoperative period, incidences of shivering were 80.07% & 50% in Group-A and Group-B which are highly significant between the groups P<.001 Cardiovascular parameters SAP, DAP, MAP and SpO2 between the groups were not significant P>.05. The study showed that patients of Group-B were less shivering with good recovery. Conclusion: In concluded that the post-operative shivering are the most common complaints. The aetiology of postoperative shivering is multifactorial including anesthetic, patients and surgical factors. Antishivering prophylaxis may be justified in patients who are at great risk of developing post-operative shivering after general anaesthesia. The incidence of major side effects is not significant in ketamine group and contributes to some extent to post-operative analgesia.

Published: May 2022

Microgrids have emerged as a new way to integrate and use large-scale distributed power to provide electricity to isolated locations, such as islands and villages. A utility engineering microgrid structure is designed to provide fast response and efficient operation by analyzing hybrid power systems and fuzzy-PI-based control techniques. This project aims to design a solar photovoltaic (PV)-battery-diesel generator-based hybrid power system employing a Sepic converter. The Perturb and Observe algorithm is used for maximum power extraction from solar panel. A lithium-ion battery is utilized as a storage battery in this system, which may be charged by the PV source. When the storage battery is depleted and PV generation is unavailable, the charging station uses the grid and a diesel generator. The generated voltage is synchronised at the Point of Common Coupling (PCC) to achieve continuous charging. The simulation is done in MATLAB/Simulink. The simulation output of using the PI control strategy is compared with the fuzzy-PI control strategy. This demonstrates the efficacy of the fuzzy-PI control method.

This article discusses contradictions involving social and territorial conflicts generated by a large-scale public water project, the communities affected by this project, and how they resisted this process, considering the historical context involving the development model imposed by capitalism in Latin America and government regulation, especially contemporary strategies to deterritorialize peasant groups. We examine the struggle by farmers in the Lapa community for the recognition of their territory and against violations of their rights after the construction of the Figueiredo dam in Potiretama, Ceará, Brazil. In our analysis, Latin American social theory and the sociology of conflicts dialog with empirical data obtained from interviews and bibliographic/documentary research conducted in 2018-2020. The farmers in Lapa were seen to utilize various forms of resistance: collective organization, activation of collective identities, occupations, social mobilizations, and maintenance of the traditional way of life. We conclude that the peasantry includes groups that resist and fight in the countryside against the fallacy of “a better life” in defense of “living well”.elocation-id: e2230112Received: 10.07.2021  •   Accepted: 03.28.2022   •   Publicado: 05.20.2022Original article  /  Blind peer review  /  Open access

Annotation
Purpose. Reducing the cost of crop production due to the use of the created standard range of multifunctional mobile energy means (MEM) such as “Autotractor”.
Methods. Analytical methods of analysis of the state of technical support of APV and technical means using the basic laws of economic theory with the subsequent processing of results by means of the personal computer.
Results. The standard size range of multifunctional mobile power vehicles of the Autotractor type, which is formed by traction forces and consists of 4 traction classes, is substantiated. The main parameters of the representatives of the size range, in particular, weight, power of the internal combustion engine, load capacity, wheel formula are substantiated.
Conclusions. According to the results of the analysis of the state of technical support of APV and equipment produced by domestic tractor plants, the main parameters of the size range of MEM type “Autotractor” are substantiated. The standard size range consists of 4 traction classes, the weight of which is in the range from 1.4 t to 13.8 t, engine power – from 30 kW to 300 kW, load capacity – from 0.5 t to 12.0 t, wheel formulas – 4×4 and 6×6, maximum speed – 80–90 km/h.
Increasing the weight of the MEM due to the weight of the ballast (load) makes it possible to increase the traction class of the MEM.
The use of mobile power facilities (MEM) makes it possible to reduce the cost of their work by increasing the annual load and reduce the cost and range of the technological fleet of farm machines by 30 % and, ultimately, reduce th cost of crop production.
Keywords: standard size range, mobile power means, autotractor, traction class.
SCIENTIST, WARRIOR, TEACHER: TO THE 100TH ANNIVERSARY OF THE BIRTH OF PROFESSOR NIKOLAI ALEKSEEVICH STRUCHKOV (13.02.1922-15.11.1989)

Статья содержит воспоминания о заслуженном деятеле науки РСФСР докторе юридических наук, профессоре генерал-майоре внутренней службы Николае Алексеевиче Стручкове. Освещается его боевой, педагогический и творческий путь. Настоящая статья направлена на то, чтобы в какой-то мере восполнить недостаток информации об основоположнике советского исправительно-трудового права, тем более что личное общение автора с Николаем Алексеевичем в последние годы его жизни позволяет это сделать. Необходимо отметить незаменимую роль Николая Алексеевича в возрождении пенитенциарной науки, которой при богатейшем спектре своих научных интересов он отдавал предпочтение, участие Николая Алексеевича в работе в составе авторского коллектива по подготовке нового уголовно-исполнительного законодательства. Идея написания данной работы заключается в следующих словах : «Как когда-то, в суровые годы войны, ветеран-гвардеец на переднем крае - трудовые дела приняли эстафету у боевых и определяют всю жизнь…». Именно этим Николай Алексеевич руководствовался в своей жизни. Также представлена выдержка из статьи автора «В труде как в бою» о Николае Алексеевиче Стручкове, опубликованной в 1988 г. в газете «За кадры» Академии МВД СССР.

The article contains memories of the Honored Scientist of the RSFSR, Doctor of Law, Professor, Major General of the Internal Service Nikolai Alekseevich Struchkov. His combat, pedagogical and creative path is highlighted. This article is aimed at filling to some extent the lack of information about the founder of Soviet corrective labor law, especially since the author’s personal communication with Nikolai Alekseevich in the last years of his life allows this to be done. It is worth noting the irreplaceable role of Nikolai Alekseevich in the revival of penitentiary science, which, with the richest spectrum of his scientific interests, he preferred. It should also be noted that Nikolai Alekseevich participated in the work as part of a team of authors on the preparation of new penal legislation. The idea of writing this work lies in the following words: «As once, in the harsh years of the war, a veteran guardsman at the forefront - labor affairs took over from the military and determine all life ...». This is what Nikolai Alekseevich was guided by in his life. Also presented is an excerpt from the article «In work as in battle» in 1988, written by the author about Nikolai Alekseevich Struchkov in the newspaper «For Kadry» of the Academy of the USSR Ministry of Internal Affairs.
INFLUENCE OF SOCIO-COMMUNICATIONAL QUALITIES ON THE FUTURE PROFESSIONAL ACTIVITY OF STUDENTS UNDER CONDITIONS OF MODERN CHALLENGES

Published: May 2022

Актуальность исследования обуславливается специфичностью современного мира, характеризующегося быстроменяющимся условиями жизни и высокими требованиями к обществу и будущим специалистам в любой сфере, в частности, к специалистам, которые будут работать в сфере физической культуры и спорта. Проблема социально-коммуникативных навыков будущих специалистов в данной сфере на сегодняшний день стоит остро, так как для студентов, являющихся одним из основных сегментов общества любого государства, чаще всего испытывающих проблему вхождения в социум, данный вопрос особенно актуален. Нынешняя эпидемиологическая ситуация и нестабильные геополитические отношения между некоторыми мировыми государствами, в число которых входит Россия, является одной из причин социального разобщения в обществе. Анализ научной литературы по вопросу изучения понятия «социально-коммуникативные качества» позволил раскрыть это понятие и установить взаимосвязь между уровнем сформированности данных качеств и успешностью в профессиональной деятельности. Для студентов, обучающихся в вузах физкультурно-спортивного профиля, планирующих продолжать свою профессиональную деятельность по специальности, особенно важно в совершенстве владеть социально-коммуникативными качествами, так как их профессия тесно связана с межличностной коммуникацией. Статья предназначена для сотрудников системы образования, руководителей образовательных организаций, студентов, исследователей.

The relevance of the study is determined by the specificity of the modern world, characterized by rapidly changing living conditions and high demands on society and future specialists in any field. The problem of social and communication skills is the most acute today. For students, who are an important layer of society in any state and most often experience the problem of entering society, this issue is especially relevant. The current epidemiological situation and unstable geopolitical relations between some world states, including Russia, are one of the reasons for social disunity in society. An analysis of the scientific literature on the issue of social and communicative qualities made it possible to reveal this concept and establish the relationship between the level of possession of these qualities with success in professional activities. For students of physical culture and sports who plan to continue their professional activities in their specialty, it is especially important to master social and communicative qualities to perfection, since their profession is closely related to communication with other people. The statements of various scientists about the role of the university in the formation and development of students' social and communicative qualities are also considered. The article is intended for employees of the education system, heads of educational organizations, students, researchers.
Perspectiva a los procesos didácticos en el enfoque por competencia
Authors: Valencia Montero María Isabel , Carvajal Tovar Sorlinda , Estupiñan Gómez Fabio Alonso
Published: May 2022

En este artículo se presenta un análisis sobre el enfoque por competencia, mediante una metodología de revisión documental, para lo cual se realiza un proceso de documentación de autores como Tobón (2005), Velázquez y Frola (2011), Badilla, quienes plantean este enfoque como una opción hacia la calidad educativa. En el proceso se evidencia que la construcción del concepto de competencias se ha visto influenciada por diferentes tendencias disciplinares y cambios en lo social y económico, contribuciones que de alguna manera han aportado en su evolución, pero también han tergiversado la esencia de lo que es formar desde el enfoque y esto ha dificultado al momento de diseñar y ejecutar un plan académico. Asimismo, se menciona que los procesos didácticos están conformados por una estructura de inicio, desarrollo y cierre, en la cual articulan una serie de secuencias didácticas para poder planificar la educación por competencias. Respecto a la evaluación por competencias se constituye en una oportunidad inmejorable para que cada persona demuestre el dominio de lo aprendido en cualquier contexto en el momento que le sea requerido, allí radica que no solo es adquirir el conocimiento, sino saberlo desarrollar y articular.
Análisis de la producción escrita de niños con síntomas de dislexia a partir de un enfoque Lingüístico-Cognitivo
Authors: González Romel , Rincón Marión
Published: May 2022

En esta investigación se analizó la producción escrita de los niños con síntomas de dislexia, pertenecientes a la segunda etapa de educación básica de la escuela "Pedro Julio Maninat" del municipio Cabimas- Zulia, a partir de un enfoque lingüístico-cognitivo, mediante el diagnóstico y clasificación de las desviaciones encontradas en la producción escrita de dichos estudiantes, apropiándonos de las teorías de Cepeda (2009), Gutiérrez (2006), Pardo (2005) y Ferreiro (2008) quienes aportan criterios de interpretación de la producción escrita de los niños. Metodológicamente, estuvo enmarcada en una investigación de tipo descriptiva, con un diseño de campo no experimental y una muestra de 70 niños con edades entre nueve (9) y doce (12) años, quienes aportaron datos a través de la producción escrita. Entre las técnicas utilizadas para la recolección de datos, estuvo la observación directa, la revisión documental sobre los síntomas de la dislexia y la aplicación de entrevistas no estructuradas de manera espontánea tanto de niños como docentes. Cabe señalar que, mediante el análisis de la producción escrita, no se puede asegurar que el educando efectivamente padezca de dislexia, ya que esta deficiencia es originada por múltiples factores, sin embargo, el 8,5% de los infantes enfrenta serias dificultades para separar o unir adecuadamente palabras, confusión de letras y falta de paralelismo de las líneas, por lo que puede confundirse con dicha anomalía.
