Argumentar por escrito en el discurso académico español
Authors: Cervera Rodríguez Angel
Published: November 2021

Introducción: Las principales competencias que han de adquirir los estudiantes a lo largo de su formación son la comprensión lectora, la interpretación comunicativa y la producción discursiva mediante una expresión correcta, razonada y coherente. De esa forma, han de saber argumentar con criterios lógico-racionales en cualquier ámbito discursivo, sobre todo en el académico. Por medio de la argumentación pretendemos transmitir el conocimiento adquirido con criterios válidos, aunque podemos aportar ideas sobre el tema desde nuestro punto de vista utilizando razones sólidas que logren convencer a quienes nos dirigimos. Metodología: El contenido del artículo se apoya en un marco teórico relevante de la lingüística del texto y el análisis del discurso, acompañado de un método analítico cualitativo aplicado a una selección de fragmentos de ensayos representativos, cuyo objetivo es reconocer y explicar los elementos lingüísticos, los recursos retóricos y los procedimientos pragmático-argumentativos del discurso académico con el fin de saber utilizarlos en las producciones discursivas.  Resultados: A través del análisis empírico y cualitativo aplicado a los ensayos seleccionados se comprueba que son textos apropiados para el discurso académico por estar dotados de organización lógica y por dominar en ellos la argumentación, la intertextualidad y la polifonía. Conclusión: Así pues, el ensayo es el prototipo de género discursivo académico español para desarrollar las competencias lingüístico-cognitivas y pragmático-comunicativas de los estudiantes

Published: November 2021

Research background. Tiger milk mushroom (Lignosus rhinocerus) is a medicinal mushroom that is geographically distributed in the region of South China, Thailand, Malaysia, Indonesia, Philippines and Papua New Guinea. Consumption of its sclerotium has been reported to treat various ailments. However, its anticancer potential towards oral cancer cell lines is yet to be determined considering the traditional method of its consumption by biting/chewing of the sclerotium.
Experimental approach. Mushroom sclerotial powder of cultivar TM02® was extracted and fractionated in a chromatographic column prior to cytotoxicity testing against a panel of human oral cancer cell lines. The capability of the identified bioactive fraction in regulating several molecules associated with its tumour necrosis factor (TNF) pathway was investigated.
Results and conclusions. 2,5-Diphenyl-2H-tetrazolium bromide (MTT) proliferation assay indicated that cell lines ORL-48 (derived from gingiva), ORL-188 (derived from the tongue) and ORL-204 (derived from buccal mucosa) were inhibited by cold water extract of L. rhinocerus sclerotia and its high-molecular-mass fraction (HMM) in varying degrees with ORL-204 being most affected. Hence, the treatment of ORL-204 with HMM mushroom extract was further investigated. HMM mushroom extract induced
apoptosis and G0/G1 phase cell cycle arrest through caspase-3/7 cleavage. Activities of MIP2 and COX-2 were downregulated by 0.2- and 4.6-fold respectively in the HMM mushroom extract-treated ORL-204 cells.
Novelty and scientific contribution. Using ORL-204, we showed that HMM mushroom extract may act via the TNF pathway at various network sites as a potential dietary compound for cancer prevention and natural adjunct therapeutic to conventional cancer treatment.
Pensamiento intuitivo, lógica y toma de decisiones
Authors:   Universidad EAFIT, Builes Roldán Isabella
Published: November 2021

Antes se creía que las decisiones se tomaban, o debían tomarse, de manera puramente racional. Sin embargo, hoy sabemos que eso es imposible, pues toda decisión humana implica componentes racionales e intuitivos. Asimismo, sabemos que la intuición tiene un rol determinante en las decisiones importantes. Por tal razón, es momento de avanzar a una mayor comprensión de los procesos subyacentes al pensamiento intuitivo y su relación con la toma de decisiones. Este libro contiene un estudio de las bases de la toma de decisiones intuitiva, desde la perspectiva de los aspectos lógicos subyacentes. Partiendo de interesantes comprensiones sobre el pensamiento y el lenguaje, se desarrolla una rigurosa articulación entre dos elementos que se plantean como opuestos, la lógica y la intuición, mostrando que ambos conceptos están muy relacionados. Los desarrollos conceptuales presentados tienen una vocación práctica, pues sientan bases para una posible comprensión, estudio y aplicación de la toma de decisiones en general, teniendo presente la responsabilidad ética que conlleva toda elección.
REINSTATING GREEK E-GOVERNANCE: A FRAMEWORK FOR E-GOVERNMENT BENCHMARKING, IMPROVEMENT AND GOVERNMENT POLICIES
Authors:   Ionian University, Kontogeorgis Georgios , Varotsis Nikolaos ,   Ionian University
Published: November 2021

This paper presents the implementation and evolution of e-governance in Greece as well as offering insights, policies and suggestions for the design of e-government benchmarks. The research objectives of this article are to identify the appraisal of Greece in e-government over time and in relation to other countries as well as the role of internal audit and transparency related to digital public services. The method adopted is through an extensive bibliographic review of the Greek, European and international literature of the thematic field of e-government as well as the presentation of several frameworks to structure the discussion of e-government benchmark design based on a benchmarking with key indicators of published surveys from internationally reputable organizations. The findings of this paper are that Greece proceeded at a very slow pace in its digital transformation, shows shortcomings in e-government policies, records delays in adapting the services requested by citizens, and no matter the lack of investment in technological infrastructure, the effectiveness of e-governance presupposes proactiveness. Nevertheless, another key conclusion of the research is that Greece is far from the average performance of e-government in the European Union due to its chronic economic problems, the lack of technological equipment and the lack of overall orientation in e-government. Furthermore, this paper can be a measure of comparison for other countries that have similar characteristics to Greece in order to improve e-governance.
IMPLEMENTATION OF MONITORING OF THE QUALITY OF PUBLIC SERVICES AT THE LOCAL LEVEL AS A TOOL FOR REFORMING PUBLIC ADMINISTRATION – THE POLISH EXPERIENCE
Authors:   University of Gdańsk, Michalski Tomasz , Kopeć Krzysztof ,   University of Gdańsk
Published: November 2021

The main aim of the article is to present a model of monitoring of the quality of public services which can be used to enhance the quality of self-government in European post-communist countries. The secondary aim of the article is to identify factors which hinder the implementation of the model. The theoretical basis for the presented model comes from three earlier ones: the Deming cycle, the Boyd cycle, and the model of institutional development of organizations. The model has been tested in 10 local administration units (LAU) in Poland. It consists of six stages presented in the article: decision to implement monitoring, its objectives and resources; selection of indicators; collection of data; analysis of the collected data and preparation of reports; use/dissemination of the reports; final evaluation of monitoring and implementation of conclusions. Three critical points were identified at which decisions to stop monitoring were often taken, namely: disappointment with the first main report which failed to answer all of the problems raised by the authorities, changes of the LAU authorities as a result of elections, and “indolence” of local authorities manifested in expecting support from outside.

Published: November 2021

This paper examines the transformational shifts in investment strategies of sovereign wealth funds. It analyzes the basic theory of sovereign wealth funds and justifies the need for its development. It identifies the similarities and distinguishing features of sovereign wealth funds. Four types of sovereign wealth funds are characterized, and the key requirements for their management system are clarified. Analysis results for the changing capital among the world’s largest sovereign wealth funds since the start of the Covid-19 pandemic are given. Market value trends of the Government Pension Fund Global (Norway) for 1998-2021 were revealed, and a prediction of its changes for the period until 2026 was created. The influence of the Covid-19 epidemic on the structure of investment portfolios (including the emergence of a new class of assets) was presented, along with GPFG’s investment strategy. Changes in the amount of NWF’s funds (Russia) for the period 2008-2021 were presented and its growth for 2022-2023 was predicted. The transformation of NWF’s liquidity regulatory structure was assessed. New trends in the investment activities of sovereign wealth funds, which occurred under the influence of the Covid-19 epidemic, were revealed. These include reduced risk appetite, increased investment activity, and a higher share of direct investments in asset portfolios. Individual sovereign wealth funds were used to compile a chart of their investment portfolios, which were diversified depending on investment goals and risk level. Recommendations for building the investment strategy of sovereign wealth funds were formulated, with a proposed algorithm for its formulation, including three consecutive stages. It is noted that the results of implementing the investment strategy of sovereign wealth funds directly depends on management quality, whose efficiency can be assessed using special indicators.
Review of highland sorghum improvement research in Ethiopia
Authors: Zigale Semahegn , Temesgen Teressa
Published: November 2021

Sorghum is the most well-known helpful cereal crop for poor farmers in Ethiopia’s dry lowland areas due to it’s a high yielding, drought tolerant, nutrient use efficiency crop that can be grown over 80 % of the worlds’ cultivated land. It has many advantages in the economic lives of the farmers in the highlands of the country. It is a source of food, feed, fuel, construction, fencing to poor farmers of Ethiopia. Though, many biological and environmental stresses are reducing grain yield increment. Foliar and grain diseases are one of the main biological stresses limiting sorghum production and productivity in the high and intermediate rainfall areas of Ethiopia. Therefore, the objective of this paper is to review the current state of highland sorghum improvement in Ethiopia’s highlands. Breeders, pathologists, agronomists, and research extension workers have all worked hard to overcome the constraints. In addition, the national sorghum research program is focusing on developing tolerant varieties that can withstand a variety of pressures by backcrossing tolerant characteristics into existing potential landraces and elite advanced lines. Due to many yield-limiting conditions, the crop’s production is well below its potential. Sorghum breeding began in Ethiopia in the early 1950s to solve important production difficulties that contributed to low productivity, and as a result, a number of improved varieties have been offered to farmers. Since 1978, research and development efforts previous to Ethiopian sorghum enhancement have been studied. Generally, believe that future productivity will most likely increase as a result of the integration of a diverse collection of mutually beneficial disciplines and organizations with varying priorities in technology development, advancement, promotion, and market/product production. Multidisciplinary methodologies, system sustainability with temporal and spatial intensification, and participation of essential stakeholders, including farmers, in the technological development, increase, promotion, and proper intervention in production are also of interest.

Authors: Krishan Kumar Verma , Chhedi Lal Verma , Munna Singh
Published: November 2021

Jatropha curcas received a lot of attention as a biodiesel feedstock in several countries around the world. The leaf area (LA) estimation is important for biological research due to its close relationship to soil fertility, plant physiological parameters, and photosynthetic efficiency. Allometric models for reliable and accurate models for estimating the leaf area of Jatropha curcas plants based on non-destructive measurements of leaf length (L), width (W), and/ or leaf margins length (P) were developed. Jatropha plant leaves were randomly selected for model construction to estimate the leaf area using L, W, and P leaf values. Simple and accurate equations were obtained, based on leaf width (AL = W1.795), R2 = 0.987, rib length (AL = L32.081), R2 = 0.989, width and rib length (AL = LW0.320), R2 = 0.997, rib length and leaf periphery segment (AL = LP1P120.274), R2 = 0.995, and half rib and width length (AL = LW/0.50.467), R2 = 0.994. The equations were accurate for estimating leaf area of small, medium, and large size of Jatropha leaves.

Patterns of use and trends in the use of medications for the control of COPD in a cohort of Colombian patients, 2017-2019 v1
Authors: Machado Alba Jorge
Published: November 2021

Introduction: Chronic obstructive pulmonary disease (COPD) affects approximately 174 million people worldwide.The objective was to determine the trends of the use of medications for COPD in a group of Colombian patients. Methods: This was a retrospective study on prescription patterns of bronchodilators and other medications used in COPD from a population database with follow-up at 12 and 24 months. Patients older than 18 years of age of any sex who had COPD between 2017 and 2019 were included. Sociodemographic variables, medications, treatment schedules for COPD, comorbidities, comedications, and the specialty of the prescriber were considered. Results: A total of 9,476 people with a diagnosis of COPD were evaluated. They had a mean age of 75.9 ± 10.7 years, 50.1% were men, and 86.8% were prescribed by a general practitioner. At the beginning of the follow-up, on average, they received 1.6 medications/patient, mainly short-acting antimuscarinics (3784; 39.9%), followed by short-acting β-agonists (2997, 31.6%) and inhaled corticosteroids (ICS) (2239, 23.6%), but 5083 (53.6%) patients received a long-acting bronchodilator. At the beginning of the follow-up, 645 (6.8%) patients were put on triple therapy with antimuscarinics, β-agonists, and ICS, and at 12 months, this rose to 1388 (20.6%). A total of 57.9% had comorbidities, most often hypertension (44.4%). Conclusions: This group of patients with COPD treated in Colombia frequently received short-acting bronchodilators and ICS, but a growing proportion are undergoing controlled therapy with long-acting bronchodilators, a situation that can improve the indicators of morbidity, exacerbations, and hospitalization.

INFLUENCIA DEL TRASTORNO MENTAL COMÓRBIDO (ESQUIZOFRENIA, TRASTORNO BIPOLAR Y DEPRESIÓN MAYOR) EN EL FUNCIONAMIENTO RÍTMICO DE PACIENTES DUALES EN TRATAMIENTO
Authors: Adan Ana , Marquez-Arrico Julia E. , Serrano-Serrano Ana Belén , Martinez-Nicolás Antonio , Navarro José Francisco
Published: November 2021

Objetivos: El presente trabajo explora la influencia del trastorno mental comórbido en el funcionamiento rítmico circadiano de pacientes en fase de tratamiento de deshabituación. La ritmicidad circadiana se ha asociado, tanto en pacientes con Trastorno por Uso de Sustancias (TUS) como en trastornos mentales graves, con la severidad sintomatológica clínica y la recuperación, pero la investigación con pacientes duales es muy escasa. Material y métodos: Se seleccionaron 114 pacientes duales varones distribuidos en tres grupos según el diagnóstico comórbido: esquizofrenia (SZ+; N=38), trastorno bipolar (TB+; N=36) y trastorno depresivo mayor (TDM+; N=40). El funcionamiento circadiano se evaluó con registros de los horarios de sueño-vigilia, la tipología circadiana (matutina, intermedia y vespertina) y la temperatura cutánea durante 48 horas (Thermochron iButton®). Resultados y conclusiones: Los pacientes SZ+ mostraron mayor cantidad de horas de sueño nocturno con un horario más tardío de despertar respecto a aquellos con diagnóstico TB+ y TDM+ (F(2,112)=7.84; p<0,001), probablemente debido a la medicación prescrita. Los grupos presentaron diferencias en la tipología circadiana (χ2(2)=12.66; p<0,05), siendo la matutina predominante en el grupo TDM+ y la intermedia en los grupos SZ+ y TB+. Ello se halla modulado por el tipo de tratamiento, la tipología matutina es más frecuente en los pacientes residenciales que en los ambulatorios (χ2(2)=10.96; p<0,001). Los parámetros de temperatura periférica cutánea evidenciaron que las principales diferencias entre grupos se detectan durante la vigilia (F(2,111)> 3,23; p<0,05), apreciándose una menor activación y más somnolencia en los pacientes SZ+, seguidos de los TB+ y TDM+. Los resultados sugieren que el tratamiento para pacientes con trastornos duales debe evaluar no sólo el sueño sino también la vigilia. En caso necesario, la implementación de estrategias cronobiológicas para potenciar la sincronización del ritmo circadiano con el ciclo luz-oscuridad puede beneficiar la recuperación y reducir el riesgo de recaída.

Published: November 2021

1.Objective: Dual diagnosis patients perpetrate crime more often than healthy individuals and is of great importance for forensic mental health services. However, in dual diagnosis patients, very little is known about factors explaining criminal behavior. This work aims to summarize the epidemiological and clinical approach of dual diagnosis patients, focusing on the Iberian Peninsula scope. Aditionaly, it aims to analyse the state of the art regarding associations between demographic and clinical factors and perpetration of crime in dual disorder patients. 2. Method: A non-systematic review of the literature is presented. Bibliographic selection was carried out through keyword research in MEDLINE and Google Scholar. 3. Results and conclusions: Perpetration of violence was independently associated with younger age, severity of alcohol use problems, lifetime trauma exposure, and higher manic symptom scores. The three drugs most commonly associated with the drugs–crime connection are heroin, crack and cocaine. A study conducted in penitentiary centers of the Interior in Spain found a high percentage of dual pathology (81.4%) In the portuguese largest security ward, in Coimbra, 40.5% of the sample had dual diagnosis disorders. Forensic units must take an integrated approach to addressing substance-use disorders. It is needed to consider not only the complexities of the substance misuse and the mental disorder, but also the offending behaviour that brought them into the forensic services. Also, social skills can effectively be improved in dual diagnosis patients. Further research is required to identify additional risk factors, such as individual substances of abuse, and establish a causal model leading to criminal perpetration.
Scanning for Cultural Competency in Online Urban Planning Programs
Authors: Garcia Brian
Published: November 2021

This article investigates online urban planning degree programs. The Covid-19 pandemic forced urban planning programs to pivot to online delivery instantly. However, there is little preexisting knowledge on online learning in place-making fields of study both in the literature and in practice. Meanwhile, working and learning from home is expected to continue as part of urban planning education and practice. The key tension of teaching urban planning online, as a traditional place-dependent field, is the starting point for our inquiry in this article. To understand the state of online urban planning programs, an internet search was conducted. A database of 176 higher education programs was created that identified only eight online programs including degree-granting and certificate programs in urban planning. These urban planning program results were concentrated in the western United States. Key challenges in online learning were identified through a literature review, including pedagogical efforts in skill transfer and multiculturalism. The eight-program curriculum strategies were analyzed through a qualitative case study analysis. A discussion on the tactics during the transition from in-person to online education in the Department of Urban and Regional Planning at California State Polytechnic University Pomona is also presented. This article provides online urban planning program information for educators currently teaching online and for those interested in creating an online program. Online programs in place-specific fields such as urban planning have particular challenges in understanding communities without site visits, ethnography, or robust in-person community engagement. Online urban planning programs must make additional efforts to achieve a social, collaborative learning and practice environment.
Modern Caesar section

As you know, under the name of the Caesar section is an operation, with the help of which in case of impossibility of giving birth per vias naturales new pathways are created for the birth of the fetus through the incision of the abdominal wall and the wall of the uterus. The idea of ​​the operation is so simple that it suggests itself. Indeed, the emergence of the idea of ​​this operation dates back to ancient times. We find indications of this method of delivery already in Greek mythology. In this way, the birth of Aesculapius took place. In ancient Rome, the requirement to perform the Caesar section indeed, on the dead was embodied in the form of a law (the so-called lex regia de inferendo mortuo) attributed to Numa Pompilius.

Published: November 2021

La creación del Espacio Europeo de Educación Superior ha traído consigo la necesidad de crear y desarrollar metodologías docentes más activas e innovadoras, que convierten al alumnado en protagonista activo de su proceso de aprendizaje y apuestan por un aprendizaje comprensivo, centrado no solo en la adquisición de conocimientos, sino también de habilidades y competencias. Una de estas metodologías innovadoras es la gamificación, que consiste en la aplicación de juegos fuera de contextos lúdicos, como pueden ser los educativos, y que ha demostrado ser una herramienta eficaz en la motivación del alumnado universitario. Es por ello que este capítulo presenta una experiencia de gamificación, en particular centrada en la aplicación de un juego de rol en materias de introducción a la gestión empresarial. El juego consiste en formar diferentes grupos de estudiantes que constituirán empresas que competirán entre sí -convirtiendo así el aula en un mercado- y deberán tomar diferentes decisiones empresariales encaminadas a maximizar el beneficio empresarial. Los resultados de la experiencia revelan que ésta contribuye al refuerzo de los conocimientos teóricos desarrollados en el aula, a la mejora de competencias como el trabajo en equipo o la toma de decisiones, o a favorecer la motivación del alumnado.

Published: November 2021

In this study, porous polylactic acid/methotrexate (PLA/MTX) scaffolds were successfully fabricated by threedimensional (3D) printing technology as controllable drug delivery devices to suppress tumor growth. Scanning electron microscopy and energy-dispersive spectrometer confirmed that MTX drug was successfully incorporated into the PLA filament. 3D-printed PLA/MTX scaffolds allow sustained release of drug molecules in vitro for more than 30 days, reducing systemic toxic side effects caused by injection or oral administration. In vitro cytotoxicity assay revealed that PLA/MTX scaffolds have a relatively high inhibitory effect on the tumor cells (MG-63, A549, MCF-7, and 4T1) and relatively low toxic effect on the normal MC3T3-E1 cells. Furthermore, results of in vivo experiments confirmed that PLA/MTX scaffolds highly suppressed tumor growth and no obvious side effects on the organs. All these results suggested that 3D-printed PLA/MTX scaffolds could be used as controllable drug delivery systems for tumor suppression.
O Sujeito Anímico e o Sujeito Espiritual em Ideias II
Authors: CADENA Nathalie Barbosa de la
Published: November 2021

In this article I intend to highlight how the relationship between psychic subject and spiritual subject is fundamental for the understanding of intersubjectivity and the life world (Lebenswelt). In Ideas II, Husserl explains how, from the self, subject and object are constituted in the world: nature, soul and spirit. These three strata of the being are known from the theoretical attitude and the spiritual attitude and, in the process, the self is explicit. In a theoretical attitude we have nature's constitution, for which the body (Körper / Leib) is fundamental. Then the constitution of objects of animic nature, human or animal, including self-perception. Assuming the spiritual attitude, the other is perceived (Urpräsenz) initially as a body together with things, and beside this perception there is an apprehension (Appräsenz) of co-given horizons. There is an identity between the body of others and mine, it is the moment of empathy (Einfühlung). The world constituted from a naturalistic or theoretical attitude is a reduction of the surrounding world (Umwelt), but the everyday world of the personalistic or spiritual attitude precedes it, the life-world (Lebenswelt). It is therefore through the personalistic or spiritual attitude that a community of spiritual subjects is constituted. Palavras-chave : Husserl; Soul; Spirit; Intersubjectivity; Life-world.

Authors: Belyanin A.F. , Bagdasarian A.S. , Nalimov S.А.
Published: November 2021

For the manufacture of electronic devices, layered structures based on substances characterized by a complex of unique properties are promising. These substances include AlN, which has the property of field emission, is a piezoelectric and wide-gap semiconductor material and has high hardness, thermal conductivity, sound speed, stability at high temperatures. To create microwave acoustoelectronic devices, AlN is promising as a piezoelectric material with a strong piezoelectric effect. The main factor determining the achievement and reproducibility of the necessary physicochemical properties of AlN films, in particular, piezoelectric ones, is the ordered structure of the film. To solve the problem of producing films with an ordered atomic structure, sputtering methods are promising, in particular, magnetron sputtering, the application of which has no restrictions on the synthesis temperature and requirements for the substrate material. The disadvantage of growing films by magnetron sputtering is the production of multiphase material, which requires careful refinement of the synthesis conditions and control of the properties of the resulting substances. The method of reactive RF magnetron sputtering on substrates of amorphous and crystalline materials grown AlN films with a thickness of 10 nm to 10 μm. It was established that AlN films consist of X-ray-amorphous and axially textured <0001> crystalline phases. Using electron microscopy, X-ray diffractometry, energy dispersive spectroscopy, and Raman spectroscopy, we studied the influence of synthesis conditions on the composition and structure of AlN films. The Raman spectra of light of AlN films with different contents and structure of the crystalline phase are shown. The piezoelectric efficiency of the films was determined on the models of delay lines on surface acoustic waves. Understanding the features of crystallization and phase transformations during film growth by spraying methods helps to create layered structures with controlled values of functional properties and operational characteristics. The ability to control the piezoelectric efficiency of AlN films by Raman spectra is shown.

The comparison of total factor productivity in the researched enterprises and in Russian enterprises in general shows that high technology enterprises are more productive than other ones. It leads to the conclusion that one could pay more attention to the key reallocation mechanisms and the mechanism of the constructive destruction. The comparison of the total factor productivity in Russia with other states shows that Russia is a country with the transition economy where there is a big necessity to stimulate innovation activity on the enterprise level and the decrease in productivity level inside the country.

The creation of materials and technologies that ensure the safety of a person and objects of his vital activity in various emergency situations is impossible without modeling the properties of the main parameters of objects that pose a threat to them. Research in this direction is relevant and timely. Comprehensive studies have been carried out in terms of creating materials, structures and technologies for armor protection, analyzing and modeling the properties and parameters of the striker (object of threat) and target (object of armor protection), special attention is paid to the process of high-speed (meeting) of the striker with the target. Various options are modeled based on the properties and parameters of objects of threat and objects of armor protection with the use of modern achievements in the mechanics of destruction processes and by solving nonlinear differential equations in mathematical modeling. The prospects for the use of porous materials and structural design have been identified and shown, and methods for their preparation have been proposed. The level of survivability of the armor protection materials was modeled depending on the parameters, including the initial velocity of the objects of threat (materials, shells and bullets).

Published: November 2021

The article analyzes the problems associated with the reform of control and supervisory activities to reduce the administrative burden on business entities. Special attention is paid to the mechanism of the "regulatory guillotine" in the Russian Federation, as a comprehensive update of mandatory requirements. This reform is especially relevant for organizations that produce high-tech products, since it is at these enterprises that the requirements corresponding to the current level of scientific and technological progress should be applied. As a research goal of the article, the authors analyzed the features of the introduction of the "regulatory guillotine" mechanism for industrial enterprises. As a result of the analysis, it is established that it is necessary to apply a process-oriented approach in the implementation of control and supervisory activities. It is determined that on the one hand, the mechanism of the "regulatory guillotine" for enterprises will reduce unnecessarily unjustified control and supervisory checks, form a system of regulation of control and supervisory activities, and minimize administrative pressure. The new regulatory and legislative framework (mandatory requirements) should be consistent and unambiguous, meeting the requirements of the time and technological development of enterprises, based on the most significant public risks. This will allow businesses to reduce costs and remove barriers to development. On the other hand, it is established that the implementation of the "regulatory guillotine" mechanism strongly depends on organizational and managerial aspects: the definition, justification and development of mandatory requirements that ensure a risk-based approach to control and supervisory activities is a difficult task for all participants of the reform, requiring them to be prompt and consistent. The implementation of the "regulatory guillotine" may take years and enterprises will have to work in the mode of uncertainty of the regulatory framework for several more years, and the establishment of a large number of uncontrolled exceptions contributes to the ambiguity of control and supervisory procedures. The article defines the difficulties of implementing the mechanism of the "regulatory guillotine" in industrial enterprises.
Substantiation of selection and dimension reduction of non-centered informative features of signals in information systems of short-range location

Published: November 2021

In this paper, we consider the issues of selection of informative features, dimension reduction of feature vectors in regression algorithms of detection and recognition of signals and interference, as well as the issues of obtaining informative features using neural network algorithms with ill-conditioned data. The problem is considered in relation to the short-range location, with large dynamic ranges of informative features and small decision intervals, when it is impossible to estimate mathematical expectations, that is, it is impossible to use adaptive algorithms. Regression algorithms for processing non-centered random signals are presented, with a priori unknown mathematical expectations of informative parameters, which consider the specificity of short-range location and use a priori information about the initial regression characteristics of informative features – multiple initial regression coefficients. Unlike it is in traditional regression analysis, the coefficients are determined through the elements of the matrices that are inverse to the matrices of the initial correlation moments. In regression algorithms, it is necessary to calculate the square error of multiple initial regression representations. The residual mean of squares of the initial regression representations are used to justify the methods for selection and dimension reduction of informative features of signals in the problems of detection and recognition of signals and interference. We give examples of application of the proposed methods for the problems of detection and recognition of a helicopter and airplane by acoustic signals when processing histograms of the distributions of the durations of intervals between zeros, samples of envelopes and samples of local extrema of the power spectral density. Good separability of the {airplane} and {helicopter} classes in the space of non-centered parameters of signals (features) is shown. The issue of obtaining regression statistical characteristics with illconditioned data is considered. If the matrices of the correlation moments of the informative features of signals and noise are illconditioned, it becomes impossible to obtain a priori information about the multiple initial regression coefficients. The possibility of using neural network algorithms to obtain estimates of the residual mean squares of regression representations and multiple initial regression coefficients through the weight coefficients on the inputs of neurons with ill-conditioned data is shown. The results can be used in short-range location systems with a large dynamic range of non-centered informative parameters, when it is not possible to estimate the mathematical expectations of the signal parameters due to the limited observation interval.
Features of the ground moving targets indication during the rotation of the phase center of a real antenna
Authors: Yasentsev D.A.
Published: November 2021

The mode of selection of ground moving targets is one of the main modes of operation of the radar observation of the underlying surface. The article discusses the features of processing a trajectory signal when detecting moving targets in a radar with synthesizing the antenna aperture due to the rotation of the real antenna phase center. To compensate for the distortion of the trajectory signal arising from the movement of a target, an algorithm is proposed for estimating the Doppler shift of the signal frequency reflected from a moving target, with its subsequent compensation.

Traditional Kalman-type tracking filters are based on a kinematic motion model, which leads to the occurrence of dynamic errors, which significantly increase during target maneuvering. One of the solutions to this problem is to develop a model of motion dynamics with the ability to adapt its structure to external influences. It is shown that the use of a dynamic model of motion in the filter, which takes into account the inertia of the target and the forces acting on it, makes it possible to significantly increase the efficiency of the state assessment. Purpose is to development of an algorithm for assessing the position of a maneuvering object, effective in terms of accuracy criterion. The use of an adaptive motion model as part of the filter provides an increase in the estimation accuracy in comparison with the classical Kalman filter, which is confirmed by the performed numerical modeling.

To determine the characteristics of optoelectronic devices, as a rule, models are used that do not take into account the peculiarities of the functioning of information tools, the conditions of visibility and observability, which does not allow to reliably assess their capabilities to obtain coordinate and non-coordinate information. Goal of the work is to investigate the model of an optical-electronic information tool in order to evaluate the characteristics and determine the possibility of obtaining coordinate and non-coordinate information in various conditions. A block model of a system for monitoring space debris in near-earth space by means of optical-electronic information means is considered. A structural diagram of the model's constituent parts is proposed. It is shown that the position of an object in the composition of space debris is determined based on the solution of the above differential equations. The interrelation of the influence of various conditions on the capabilities of optoelectronic information facilities, on the processes of detection and tracking is described. The equations and relationships underlying the model of operation of the optoelectronic information facility are described. The results of modeling are presented, which allow planning the rational placement of optoelectronic information facilities. The presented model makes it possible to obtain initial data for planning the rational placement of optoelectronic information facilities and to substantiate the requirements for their technical characteristics.
