Published: February 2022

With a perseverance worthy of a better application, humanity throughout its history has been creating means of defeating its own kind. The stone ax and club were replaced by such tools as a knife, an arrow, a dart, a battle ax, a saber, a sword, etc. With the invention of gunpowder, the era of firearms began, which began to improve rapidly and over a relatively short period of time - about 200 years, has undergone dramatic changes. However, no matter how condescendingly today we look at the guns of the era of Peter the Great, a qualitative leap in the development of means of destruction of manpower occurred precisely when the first shot from a primitive gun sounded.

Authors:   , Alhazmi Rehab Elaithah , Fisher Kathleen Mary
Published: February 2022

Mental illness stigma has been identified as a global problem. It occurs in the community and even among healthcare professionals who possess the education to know differently. This sequential explanatory mixed methods study explored the relationship between burnout and mental illness stigma among mental healthcare professionals in Saudi Arabia. The study utilized the Attributional Questionnaire (AQ-9) and the Maslach Burnout Inventory, Human Services Survey (MBI-HSS) to assess whether burnout was related to mental illness stigma. A total of 101 subjects included nurses, psychiatrists, psychologists, and social workers participated in the study. Data analysis showed a statistically significant relationship between the predictor variable depersonalization (DP) and mental illness stigma for nurses and non-nursing healthcare professionals. In addition, emotional exhaustion (EE) was a statistically significant predictor of mental illness stigma for non-nursing healthcare professionals. A statistically significant difference in personal accomplishment (PA) levels between nurses and non-nursing healthcare professionals was found, where nurses experienced a low sense of PA. Also, the findings showed that nurses experienced high EE, DP, and mental illness stigma compared to non-nursing healthcare professionals. The information gathered during the interview with four nurses provided an explanation of factors that contributed to high burnout and mental illness stigma among nurses. Factors that contributed to burnout were the COVID-19 pandemic, long shift hours and workload intensity, staff shortage and nurse-to-patient ratio, time management skills, nature of psychiatric illness, and education. Moreover, factors that contributed to mental illness stigma were education, community, and the media. The result of this study could help to design programs that decrease stress and mental illness stigma in the workplace in Saudi Arabia.

Published: February 2022

En este artículo se plantea un método destina- do a la planificación de misiones globales para vehículos aéreos no tripulados (UAVs, por sus siglas en inglés) en función de unos requerimientos iniciales específicos. La planificación es realizada en un entorno 3D. La metodología seguida está basada en la implementación del algoritmo Fast Marching Square (FM2) para generar la ruta más corta en tiempo entre dos puntos, el cual incluye dos parámetros de ajuste. Estos dos parámetros de ajuste modificarán el primer potencial (W) generado por FM2 para adaptar la trayectoria resultante de acuerdo a unas necesidades iniciales, como pueden ser, el ahorro de energía o combustible, o simplemente el rastreo de una zona específica, lo que da lugar a una minimización de costes en términos generales. Diferentes simulaciones se han llevado a cabo obteniendo buenos resultados.

Published: February 2022

Este trabajo tiene como objetivo contribuir al uso de técnicas de Computación Inteligente para la obtención, en este caso, de un modelo perfectamente funcional de un sistema MIMO (Multi-Input Multi- Output) de tipo Twin-Rotor. Dicho sistema presenta en determinados puntos de trabajo un elevado grado de no linealidad debido a las características intrínsecas del mismo, donde sus dos entradas y sus dos salidas quedan fuertemente acopladas, poniendo en compromiso sus condiciones de estabilidad, ante estrategias de control tradicionales. Este sistema consta de un rotor superior y otro lateral de cola, que controlan el Pitch y el Yaw respectivamente. El modelo neuronal NARX obtenido se presenta como una caja negra (“Black-Box”) que reproduce de forma aproximada la dinámica del funcionamiento del sistema, manteniendo los comportamientos no lineales más generales, tal y como lo demuestran los resultados presentados.

В условиях интенсивной цифровизации всех сфер общества происходит интеграция деятельности организационных систем с цифровой средой управления. Для этих целей выделяется адресное ресурсное обеспечение. Актуальной становится задача оптимального распределения этого ресурса. Рассматривается применение оптимизационного подхода при распределении ресурсного обеспечения по развитию цифровой среды управления. При этом управляющий центр организационной системы направляет деятельность на достижение заданного уровня показателей эффективности. Ресурсная поддержка выделяется на компоненты цифровой среды, которые в наибольшей степени способствуют решению этой задачи. Для реализации оптимизационного подхода сформирован комплекс формализованных моделей принятия оптимизационных решений в виде задач многоальтернативной оптимизации и линейного программирования. Алгоритмизация оптимального распределения ресурсного обеспечения за период развития позволяет интегрировать в цифровую среду управления наиболее значимые компоненты для поддержки заданного уровня показателей эффективности и осуществить ресурсную поддержку в определенные временные интервалы мониторинга и принятия решений.

In the context of intensive digitalization of all spheres of society, the activities of organizational systems are integrated with the digital environment for their management. For these purposes, targeted resource support is allocated. The problem of optimal distribution of this resource is becoming urgent. The article discusses the use of an optimization approach in the distribution of resource provision for the development of a digital management environment. At the same time, the control center of the organizational system directs activities to achieve a given level of performance indicators. Resource support is allocated to those components of the digital environment that are most conducive to solving this problem. To implement the optimization approach, a complex of formalized models for making optimization decisions has been formed in the form of multi-alternative optimization and linear programming problems. Algorithmization of the optimal distribution of resource provision over the development period allows integrating the most significant components into the digital management environment to maintain a given level of performance indicators and provide resource support at certain time intervals for monitoring and decision-making.

The scheme of distributed data processing using a parallel computer is built. A scheme of a digital data processing system using a two-tier architecture is proposed. A change in the scheme in the form of optimization for the use of the fast Fourier transform in base 4 is proposed. Two variants of implementation are shown, and an estimate of the computational efficiency of this transition is given. The practical significance of the research presented in the article lies in explicitly proposing the structure of a solver that has a higher computational efficiency compared to a similar one that uses the fast Fourier transform in base 2, as well as in the development of a scheme for including such decisive (computational) nodes in a computational cluster. The place of the control module, which forms a dynamic plan for the use of resources, is shown. This material will be of interest to radio amateurs, as well as to students and workers in the field of radar surveillance data processing.

VERSÕES E CONTROVÉRSIAS SOBRE O AI-5: OS ECOS E REPERCUSSÕES DA DITADURA MILITAR NO BRASIL
Authors: Fidelis Thiago , Francklin Adelino , De Almeida Teles Janaína
Published: February 2022

Este texto tem por objetivo analisar os ecos autoritários herdados da ditadura militar (1964-1985) no Brasil da atualidade, a partir das declarações e mobilizações políticas realizadas entre 2019 e 2020, nas quais prevaleceu a defesa do Ato Institucional nº 5, de 13 de dezembro de 1968, medida que suspendeu as liberdades individuais e garantias civis previstas pela Constituição de 1946, inaugurando o período mais coercitivo da ditadura militar. Para melhor compreender esse contexto histórico, o presente estudo debate o retorno do pensamento autoritário ao centro da política brasileira, por meio de um diálogo com as intepretações historiográficas a respeito do golpe civil-militar de 1964 e o aprofundamento da institucionalização do estado exceção estabelecido com a edição do AI-5. Para tanto, o estudo pretende apresentar um panorama crítico do contexto histórico no qual o AI-5 foi promulgado, estabelecido à luz das evidências e investigações mais recentes sobre o período e o ato mais autoritário entre as medidas de exceção editadas pela ditadura militar.
Cambios en los patrones espaciales de área quemada en Colombia, ¿qué ha pasado en las dos primeras décadas del siglo XXI?

Colombia ha venido avanzando en el monitoreo anual de los incendios forestales y el área quemada y su relación con las variaciones en un mismo año y de un año a otro de las condiciones climáticas que los propician, así como de las causas antrópicas que los generan. A nivel mundial se habla de cambios en el régimen de incendios, no obstante, en Colombia todavía no se ha determinado si la tendencia en el tiempo es de aumento en la extensión, tamaño y frecuencia de los incendios. En este estudio se presenta un análisis comparativo de las dos primeras décadas del siglo XXI en términos de los patrones espaciales y temporales de las áreas quemadas, con el objetivo de analizar cambios en algunos parámetros del régimen de incendios en el país (extensión total, tamaño, configuración espacial de los parches quemados y frecuencia). Se utilizó la información del producto de área quemada mensual Fire_cci v5.1 derivado del sensor MODIS a una resolución de 250 m para mapear mensualmente todos los parches detectados como quemados o las cicatrices de quemas desde enero del 2001 hasta marzo del 2020. El área quemada presentó una gran variabilidad anual y en el curso del año, siendo febrero y enero los meses más afectados por incendios. El área total quemada en un mes ha tendido a disminuir en la segunda década del siglo XXI, pero el tamaño promedio de los parches quemados ha aumentado de 188,75 ha en promedio en la primera década a 196,2 ha en la segunda década, durante la cual también se han detectado un mayor número de fragmentos. En términos de frecuencia, se encontró una gran variabilidad con zonas, especialmente las bajas, donde ha aumentado la frecuencia en la segunda década comparada con la primera. Se confirmó un cambio en algunas propiedades del régimen de incendios en Colombia, ya que, aunque el área total afectada disminuyó y los incendios menores se redujeron, el patrón encontrado indica una clara tendencia a más incendios de mayor tamaño y frecuencia.
Responsabilidad social y remediación: casos de buenas prácticas

Published: February 2022

Responsabilidad social y remediación: ejemplos de buenas prácticas, investigación realizada y financiada por la Universidad Militar Nueva Granada en la convocatoria Ciencia al Servicio de la Paz 2017, contó con la participación del Instituto Interamericano de Responsabilidad Social Empresarial y Derechos Humanos (IIRESODH). El propósito del documento es presentar un parámetro de caracterización de una buena práctica y aplicarlo al principio rector de remediación, en el cual se consideran criterios internacionales y nacionales que incluyan además estándares de responsabilidad social empresarial (RSE). Para lograrlo, se incluyen casos de diferentes sectores económicos. El estudio aborda los siguientes aspectos: primero, se desarrollan los conceptos básicos de rse y los Principios Rectores sobre las Empresas y los Derechos Humanos de las Naciones Unidas de 2011; luego, la remediación en derechos humanos (DD. HH.), su relación con la reparación judicial y administrativa y, después, se definen las buenas prácticas y la remediación y se llevan a cabo análisis sobre los casos seleccionados. Además, concluye que se deben visibilizar las acciones que se desempeñan en virtud del principio de remediación, puesto que estas dan cuenta del éxito de su labor en la implementación de los Principios Rectores sobre las Empresas y los Derechos Humanos y de las acciones en RSE. Es necesario enfatizar en la remediación en la política nacional de empresa y DD. HH. para posibilitar el entendimiento y emprendimiento de las compañías en la materia. Tras el desarrollo de la investigación, se recomienda la creación de lineamientos de políticas públicas que potencialicen la presencia de buenas prácticas en remediación y generen un acercamiento con las empresas, para buscar que dejen atrás la percepción negativa de la remediación y, en consecuencia, empiecen a visualizarla como un mecanismo de mejora. Asimismo, es necesaria la capacitación del sector empresarial al respecto, con especial énfasis en el núcleo de remediación y sus beneficios.

Innovation changes and the traditional financial sector

Published: February 2022

Purpose of the study: The main objectives of this work are to analyze the innovation process in general and financial Innovation in particular, during which potential effects will appear on the financial structures of economic units and considering the recent financial events of the crisis of the subprime discuss whether financial Innovation is a source of growth or, on the contrary, is a source of financial instability.

Methodology: The financial crisis has cast a shadow over recent financial innovations, particularly those that call for risk elimination. This research used secondary methods for innovation changes and traditional financial sectors. The secondary research method will collect data through google, websites, books, and other sources.

Main findings: The main goal of financial technologies offered by entities in this sector is to improve the efficiency and availability of financial services, both from the customer and the perspective and a financial institution. The digital economy is considered a vertical—data-focused, and connected economy to the device, with a centralized architecture and heavy technology.

Application of the study: In debates about the regulation of financial markets, the functions and social use-value of financial Innovation come under scrutiny. In developing countries, the crucial question arises of to what extent financial innovation is essential to creating the financial infrastructure necessary for industrialization, instead of simply making wealth more liquid where blockchain technology and cryptocurrencies and crypto money become more active.

Originality/Novelty of the study: In this way, new products have been created, new forms of derivatives, products that transfer risk, and so on. It should be borne in mind, in any case, that the Schumpeterian vision of the innovation process in the present case that of financial Innovation is part of a regular course in terms of an economy that seeks growth. However, the financial crisis has cast a shadow over recent financial innovations, particularly those that call for risk elimination.
