Forgotten officials: social and cultural characteristics of junior employees оf Odesa postal‑telegraphic districtаt at the end of the 19th – the beginning of the 20th century
Authors: Fedorchenko Oleh , Kaminskaya Olena
Published: January 2022

The aim: based on archival statistical materials, to create a socio-cultural portrait of lower employees of post and telegraph offices of Tavriya and Kherson provinces: class and group affiliation, educational level, age, religion, and dynamics of social-cultural portrait changes. Research methods: historic-genetic, historic-systemic, comparative. Main results: The dynamics of changes in the constituents of the socio-cultural characteristics of the lowest level employees of the Post department is analyzed. It is noted that, contrary to the government’s desire to form a generation of agents, the corps of the lowest level employees was formed, first of all, from peasants and burghers, who were attracted by the opportunity to get a rank and rise in the hierarchy of the Russian Empire. The educational level of the guards was increased at the expense of women, who, from 1916 were allowed to occupy positions of the lowest level employees. The educational indicators of postmen declined as the administration of post offices gave preference to physically fit people. Considering the religiosity of the society of the Russian Empire, most of the messengers were Orthodox. More than half of the messengers were married, which ensured a stable staff of lower-level employees. The practical significance lies in the creation of a systematic, factual basis for the reconstruction of the history of the Post office in Ukraine at the end of the 19th – beginning of the 20th centuries, in particular, the study of the ”human factor” of the Post department functioning. The originality of the research lies in the use of a wide range of unpublished archival sources and their comprehensive analysis. Scientific novelty: the main characteristics of the composition of the lower employees of the post and telegraph offices of Tavriya and Kherson provinces are comprehensively presented for the first time. Age, status, educational, family components and their changes are analyzed. Type of article: descriptive and analytical.
Eneolithic Bronze Age mound near the village of Katerynivka in the Middle Prisamarye
Authors: Marina Zoia
Published: January 2022

The purpose is to analyse the materials of the mound near Katerynivka in the Petropavlivsky raiion of the Dnipropetrovska oblast studied by the expedition of the Oles Honchar Dnipro National University in 2016. Research methods: descriptive, typological, chronological, comparative historical. Main results. The mound construction and 13 burial complexes of the Eneolithic – Bronze Age are analyzed. At the time of the excavations, the mound located on the edge of the high root cape of the Samara River was significantly damaged due to anthropogenic activity. There are difficult ritual actions in the main Eneolithic burial № 9. The tomb has stone mortgage and cromlech with diameter on the Nord-South direction equal 5.2 m. The skeleton of an adult is stretched out on his back, head to the South. The chalk sprinkling is fixed on the bottom. The miniature molded pot from the main Eneolithic tomb № 9 belongs to ceramics of the Zhyvotylivsky culture type. Tombs no. 2–8, 10, 13 belong to Yamna culture. Rectangular tombs are made with the use of wood in the floor. Plant litter and ocher is found in the bottom of the graves. The skeletons are bent at the back, oriented in the western semicircle (two cenotaphs). Two tombs are without skeletons. Concomitant equipment includes an egg-shaped pot and a flint chip. For some of the burials, backfilling was carried out mainly in the southern direction (to the edge of the cape), which necessitated the strengthening of the embankment in the form of a stone lining up to 3.5 m wide with small stones in this direction. Tomb no. 12 belong to the Catacomb culture. It is located in a tomb with a round entrance well and an oval chamber attached to it. The skeleton of a young man or a young woman lay twisted on the right side, head to the northeast. The remains of a lamellar bronze bracelet are on the ankle of the right leg. Log burials (no. 1, 11) are represented by skeletons bent on the right side in the northeast and northwest orientation. The ceramic is represented poorly. Conclusions. The ancient mound was built in the Eneolithic period. Other constructions represent different periods of the Bronze Age. Practical meaning: the published materials can be used in generalizing research of the problems of archeology of the Eneolithic – Bronze Age of Ukraine. Scientific novelty: cultural and chronological features of the mound near Katerynivka in the Petropavlivsky raiion in the Dnipropetrovska oblast are determined. Type of article: analytical.

Tendencias y desafíos en la creación de metadatos en proyectos de archivo de la web
Authors: Blanco-Rivera Joel Antonio
Published: January 2022

Este trabajo tiene como objetivo identificar prácticas y desafíos relacionados al manejo de metadatos en proyectos de archivado web. Se lleva a cabo un análisis de literatura sobre sobre metadatos en archivos de la web publicadas desde 2013, con particular atención a identificar estudios sobre estas prácticas en archivos y bibliotecas. Estos hallazgos apuntan a la necesidad de proveer una mayor contextualización sobre la conformación de un archivo o colección web, así como la importancia de tender puentes entre prácticas bibliotecológicas y archivísticas. Además, para profundizar sobre la importancia de los metadatos en proyectos de archivo de la web, se presenta como estudio de caso la conformación y catalogación de la Colección Web #RickyRenuncia, que forma parte del Proyecto RickyRenuncia, una iniciativa colaborativa y voluntaria para documentar las protestas que llevaron a la renuncia del gobernador de Puerto Rico en julio de 2019. A manera de conclusión, se argumenta sobre la necesidad de conocer más sobre prácticas de archivado web en Latinoamérica y el Caribe, y sobre la posibilidad de establecer redes de colaboración dirigidas a fortalecer la preservación de contenidos web en la región.

Authors: Castillo-Madrigal Josué , Pozos-Guillén Amaury , Gordillo-Moscoso Antonio
Published: January 2022

Temporomandibular joint dysfunction syndrome (TMD), is a collective term characterized by symptoms involving chewing muscles, temporomandibular joint and orofacial structures. The efficacy of low intensity laser (LLLT) Gallium arsenide, in combination with a non-steroidal anti-inflammatory drug (NSAID) was evaluated. The main objective was to evaluate the maximum mouth opening without pain (ABM), arthralgia in the joint capsule through visual analog scale (VAS), laterality, protrusion, joint noises and count of tablets ingested per group. A controlled clinical trial (double-blind-randomized) was carried out in 30 subjects, who presented DTM of arthrogenic etiology; 5 applications of LLLT were made with wavelength of 810 nm, output optical power of 100-200 mw, emission PW=Pulsed (1-10,000Hz), dose of 10 jouls-cm², time of 1.44 minutes in mouth closed and with the mouth half open. One more follow-up appointment per month. There were two groups: experimental and control group, where different variables were analyzed (ABM, laterality, protrusion, VAS and sociodemographic). In the control group, a supposed LT application (not active) was made, for later comparison. Pain-free ABM was assessed in all appointments in addition to the other clinical parameters. Repeated measures analysis was performed with mixed models. Thirty patients were included of which 28 finished the treatment, two of them were lost during follow-up. The groups were similar in all their baseline variables. There were no statistically significant differences when applying the final multiple regression analysis, in the ABM, or in any other of the clinical parameters analyzed. LT was not effective in treating arthrogenic DTM.
Identificación de aberraciones cromosómicas en una población infantil costarricense con discapacidad intelectual idiopática
Authors: Abarca Ramírez Melissa , Morales Montero Fernando , Vindas Smith Rebeca , Ortiz Morales Fernando , Castro Volio Isabel
Published: January 2022

La prevalencia mundial de la discapacidad intelectual (DI) es del 3 %. Una de las causas más comunes de DI de origen genético son las aberraciones cromosómicas, las cuales resultan fácilmente detectables mediante un cariotipo. Sin embargo, muchas de estas pasan desapercibidas durante el análisis citogenético convencional debido a su tamaño. Estas pequeñas alteraciones se pueden localizar en los subtelómeros y se ha observado que, cuando es así, constituyen una razón importante de DI en pacientes que carecen de un diagnóstico de causalidad. En este estudio de tipo observacional, se utilizó la técnica MLPA con el objetivo de determinar la frecuencia de aberraciones cromosómicas submicroscópicas en los subtelómeros en una población infantil con DI de origen desconocido. Se examinaron 70 muestras de forma exitosa y se obtuvo un caso con una microduplicación en el subtelómero 17p, para una frecuencia del 1,4 %. También, se realizó el análisis citogenético en 33 muestras y se encontró un caso con una aberración cromosómica detectable al microscopio, para una frecuencia del 3 %. El porcentaje de aberraciones cromosómicas subteloméricas fue menor al esperado en comparación con estudios similares. Finalmente, se concluyó que el cariotipo y la técnica MLPA se complementan para el abordaje de personas con DI de origen desconocido.
Consumo de alimentos altamente procesados y de alta palatabilidad y su relación con el sobrepeso y la obesidad
Authors: Vindas-Smith Rebeca , Vargas-Sanabria Dayana , Brenes Juan C.
Published: January 2022

Introducción: la obesidad es un rasgo multifactorial determinado por la interacción de factores biológicos, ambientales, psicosociales y político-socioeconómicos. Propósito: el objetivo de esta revisión descriptiva-exploratoria es discutir el papel del consumo de alimentos altamente procesados y de alta palatabilidad (APAP) en la epidemia de la obesidad, así como presentar algunas propuestas para disminuir su ingesta. Argumentos para la discusión: los APAP se caracterizan por ser energéticamente densos, ricos en grasas y azúcares. En su formulación se utiliza una gran cantidad de aditivos industriales para potenciar su sabor, vida útil y la estabilidad de sus componentes. Suelen contener sustancias químicas conocidas como disruptores endocrinos (EDC) que se transfieren de los empaques al alimento, como el bisfenol A y los ftalatos, y afectan distintas vías de señalización hormonal, promoviendo alteraciones en el metabolismo del tejido adiposo y otros sistemas endocrinos. El sobreconsumo de APAP induce a cambios neuroplásticos en el sistema de recompensa y esto aumenta, a la vez, el número de porciones, con la subsecuente acumulación de grasa corporal; además, dicho abuso causa desbalances en la composición del microbioma intestinal (disbiosis) asociados al desarrollo de obesidad. Conclusiones: el sobreconsumo de APAP incrementa el riesgo de obesidad y enfermedades crónicas no transmisibles, máxime si se inicia a edades tempranas. Para contrarrestar esta problemática, se plantea cambiar la estructura de la canasta básica, regular la venta dentro y alrededor de centros educativos, crear mayores impuestos y fortalecer la investigación en obesidad, APAP y EDC.
Modelo preclínico de obesidad basado en alimentos altamente procesados y de alta palatabilidad
Authors: Quesada Dayana , Hernández-Solano Mónica I. , Brenes Juan C. , Vindas-Smith Rebeca
Published: January 2022

Introducción: el alarmante incremento de la obesidad en todo el mundo y en Costa Rica responde principalmente a modificaciones en la composición de la dieta habitual de las personas. La presente investigación tuvo como objetivo implementar un protocolo de alimentación formulado a partir de alimentos altamente procesados y de alta palatabilidad (APAP) consumidos por la población costarricense para, luego, evaluar sus efectos en la conducta alimentaria y en parámetros biométricos y bioquímicos. Metodología: ratas adultas macho Wistar se asignaron a dos grupos. Al primero se le administró alimento estándar para roedores (grupo DC) y al segundo, alimentos APAP (grupo APAP), durante ocho semanas. Resultados: a lo largo de ese periodo, los animales expuestos a los APAP exhibieron mayor ingesta y energía, caracterizadas por un alto consumo de grasas y uno menor de proteínas y fibra; además, mostraron un incremento significativo en los diversos parámetros de obesidad (e. g., peso corporal y ganancia de peso, índice de Lee y adiposidad central) y niveles descriptivamente superiores de glucosa y triglicéridos en sangre, pero notablemente menores de colesterol total. Conclusiones: los resultados indican que una dieta basada en los alimentos APAP más frecuentes en la población costarricense es capaz de inducir hiperfagia y obesidad. Así, este modelo constituye una herramienta prometedora para ahondar en el estudio de las factores neurobiológicos y metabólicos relacionados con la obesidad por el sobreconsumo de alimentos APAP.
STUDY ON THE LEVEL OF DISASTER PREPAREDNESS AMONG VETERINARY PRACTITIONERS
Authors: Balieva G. , Ivanov V.
Published: January 2022

PURPOSE: This study was focused on veterinary practitioners in Bulgaria with the aim to investigate and present their level of preparedness for disaster response and continuance of professional activities after disaster events. METHODS: A sociological survey through a questionnaire with open and closed questions was sent to veterinarians throughout the country personally or via e-mail. RESULTS: Veterinary practitioners in Bulgaria are not legally engaged in disaster prevention, excluding the prevention of contagious animal diseases. At the same, time veterinarians could assist the population not only in case of biological contamination but also in any crisis situation caused by natural, technical, and human factors. The study showed that one-third (34.38%, n=11) of the respondents had supplied their practices with emergency equipment, while 75% (n=24) of them had secured the continuity of communications. Another 21.88 % (n=7) of respondents had arranged in advance a meeting place for staff after evacuation to meet and plan the reorganization of their activities. Only 3.13% (n=1) of the respondents had conducted simulated evacuations in arranged training. CONCLUSIONS: The findings could be used for drafting guidelines and teaching materials for professional training, enhancing the veterinary practitioners to perform more effectively in emergencies and thus raise the disaster resilience of the community as a whole.

Sanskritisation of the Muttappan Cult: A new hermeneutic for the Muttappan legend and ritual
Authors: Gabriel Theodore
Published: January 2022

'Sanskritization' is a term coined by the reputed Indian anthropologist M. N. Srinivas, initially in his seminal thesis on the Coorgis of South India. Srinivas wanted to challenge the notion that caste is a rigid and inflexible phenomenon and that it has always remained inviolable and accepted in toto by the people in the lower echelons of the caste hierarchy.
Introduction
Authors: Pye Michael
Published: January 2022

In Japan well-established Shintō shrines form a nation-wide network forming the sites around which two types of pilgrimage, mainly but not exclusively Buddhist, occur: single shrine pilgrimage and pilgrimage to several shrines in sequence (circulatory). The subject of this book is circulatory pilgrimage. The two most famous circulatory pilgrimage routes form a model for all of the others: the Saikoku Pilgrimage comprising 33 temples in Western Japan and the Shikoku Pilgrimage comprising 88 temples on the island of Shikoku. The book uses three organizing concepts in the phenomenology of pilgrimage: route (the geographic patterns followed), the performed rites of transaction, and the dimension of Buddhist meaning. Various theories of pilgrimage are examined including Viktor and Edith Turner’s liminality and communitas, commercialized tourism and locality/sacred space and a general definition of pilgrimage is given.
The Shikoku Pilgrimage
Authors: Pye Michael
Published: January 2022

This chapter examines the second major pilgrimage route of Japan - the chain of eighty-eight temples spread through the four prefectures of Shikoku, the fourth largest island. Although the Saikoku pilgrimage has a greater claim to antiquity, many people, and not only devotees of the Shingon Buddhist sects, would regard the Shikoku route as the most prominent symbol of all Buddhist pilgrimage in Japan. It has received the most interest from foreigners including the first to write about it, the German Alfred Bohner in 1931. The 88 temples of the Shikoku Route were reputedly designated by Kūkai (Kōbō Daishi), the founder of Japanese Shingon Buddhism. The chapter looks at each of the 88 temples along with imitations and miniature Shikoku pilgrimages.
Right Speech: What I Say
Authors: Hunt Geoffrey
Published: January 2022

We generally pay little here-and-now attention to the assumptions and intentions underlying our speech. The Buddha analyses speech with his aim of understanding how we fail to see the Path and how, seeing it, it can lead us to peace. The Buddha distinguished between skilful speech and unskilful speech. That is, between the ignorant speaking that springs from our craving, clinging and our rejecting and the wise speaking that springs from letting go of that triumvirate in favour of compassion, generosity and gratitude. Speaking, we discover, is a manifestation of the ontology (the structure of reality) of ‘I-me-mine’ – which is ultimately where the trouble and the solution lie. With Right Speech we have started the path to uncovering the self.
Right Livelihood: How I Live & Work
Authors: Hunt Geoffrey
Published: January 2022

For lay people it is especially helpful that the Buddha does not limit himself to addressing monks and nuns, but examines everyday living and working, in the light of his general ethical teaching. For him ‘Right Livelihood’ is a mode or style of living, or subsistence that does not cause unnecessary harm to people or other living things, and avoids exploitation. Instead, he shows how the Path must promote caring, honest, fair and accountable relations in all encounters with people and other living things.
Right Mindfulness: Insight
Authors: Hunt Geoffrey
Published: January 2022

We now run through the first three ‘Foundations of Mindfulness’ with some simple exercises. (We shall return to the fourth foundation in Chapter 17). By a ‘foundation’ of mindfulness is meant a category of those things we can be mindful of. In this chapter there is a quick description of the four: 1. the bodily experience (e.g. skin sensations), 2. the pleasure/pain experience (e.g. an insect bite, a delicious morsel), 3. the meditational quality of the mind (e.g. whether it is concentrated or not), 4. a reflexive evaluation of one’s meditational journey and its landmarks (e.g. the struggle with hindrances and the cultivation of good will). Instructions are hen given for Walking Meditation, Standing Meditation and for the keeping of ‘states of mind’ diary. These lead to a recognition of the crucial breakthrough to ‘three marks of existence’: anxiety or suffering, impermanence, and not-self (insubstantiality).
Essentialism in Early Shinto Studies
Authors: Rappo Gaétan
Published: January 2022

In earlier years Western ideas on Shinto were strongly influenced by “nativist” (kokugaku) ideas on the subject emanating from Japan and hence tended to showcase a very “essentialist” view of Shintō. This paper critiques various Western writers whose writings were typical of this approach. However the paper also explores how this attitude had a reverse influence on pre-war Japanese thinkers. This was especially the case with Hiraizumi Kiyoshi, a scholar who became a major figure in the production of the extreme imperialist ideology of the early Shōwa period. He was also a major source for discourses comparing the Japanese spirit to Nazi ideals, which were created mostly by contemporary German scholars. The origins of this process can be seen in Hiraizumi’s sojourns in Europe, especially in France, Germany and England, from 1930 to 1931.
Why does Shin Buddhism Reject the Worship of the Kami?
Authors: Rhodes Robert
Published: January 2022

It is well known that most Japanese people possess multiple religious identities, stereotypically praying at Shinto shrines on New Year’s Day, getting married at a Christian church and holding funerals at Buddhist temples. Several Japanese religions however, notably Shin Buddhism, have rejected this pluralistic stance. Here the reasons for Shin Buddhism’s formal rejection of kami worship, a position known in as jingi fuhai 神祇不拝, are considered. Second a more conciliatory position towards the Japanese kami is considered, which arose under the influence of Zonkaku存覺 (1290-1373) and Rennyo 蓮如 (1415-1499). Third, two stories in Gōzei’s仰誓 (1721-1794) Myōkōnin-den 妙好人伝 (Biographies of the Myōkōnin) from the late Edo period are explored to see how he sought to promote the normative Shin Buddhist position towards the kami, even while presenting evidence that it was not always strictly observed in practice.

Published: January 2022

In the proposed paper, we study one composite optimal control problem described by a set of ordinary differential and integral equations. Admissible controls are selected from the class of piece­wise-continuous functions. First, the calculated formula for the increment of the second-order quality functional. Then, assuming that the control domain is convex, a necessary first-order optimality condition is proved in the form of a linearized maximum condition. The case of degeneration of the linearized maximum condition (quasi-special case) is considered. The necessary conditions for optimality of quasi-singular controls are established. In the particular case, from the necessary optimality condition of the second order an analogue of the Legendre – Klebsch condition is obtained.

Published: January 2022

The problem of asymptotic stability for autonomous functional differential equations is studied on the basis of the investigation of the roots of the characteristic function. We apply D-decomposition method for obtaining the sharp boundaries of stability domains. We obtain necessary and sufficient conditions of asymptotic stability for two families of linear autonomous differential equations with distributed delay and power kernels. These criteria of stability are formulated in terms of the parameters of the original problem. Based on the criteria, we find absolute stability conditions for each of the families.

MATHEMATICAL MODEL OF ARTIFICIAL ELECTRICAL CAPACITY FOR REDUCING THE PEAK LOAD OF MANOVER HEAT
Authors:   Kurgan State University, Popov Igor
Published: January 2022

The possibility of equipping a shunting diesel locomotive with an inert-capacitive energy storage device is being considered, which will smooth the load on the power plant and thereby reduce its power and mass and dimensions. The relatively frequent change in the operating mode of a shunting locomotive determines the efficiency and feasibility of equipping it with an energy storage device. In addition to smoothing the load on the power plant, the drive will allow energy to be recovered during braking, thereby increasing the energy efficiency of the shunting diesel locomotive. The theoretical background for creating an inert-capacitive energy storage device, which is technically designed as a DC machine with a super flywheel, is presented. The use of flywheels on shunting diesel locomotives is justified by virtue of not rigid requirements for the total weight. Another advantage of the locomotive is the presence of an electromechanical transmission, which minimizes the development for it of the considered inert-capacitive drive

The simple nonstationary random process with the sufficiently smooth realizations is considered. On the basis of kinetic modelling, the governing parameter of the process is represented for the each realization as the function of time and parameters of the kinetic equation. According to the realizations, these parameters represent the system of random quantities. As a result, the nonstationary random process is represented by the usual function of system of limited number of random quantities. For the purpose of reliability, the numerical characteristics of this process are determined by two approximate methods: linearization of function and analysis using the hypothesis of the normal distribution of the system of random quantities. The proposed lemma along with the hypothesis of the normal distribution of the system of random quantities gives the analytical expressions for the numerical characteristics up to the correlation functions for the process and for its rate. It is noted that just the expression for the expectation value contains the variances of the random quantities. In this connection, the variance restrictions are obtained. It is shown that for the both approaches the numerical characteristics converge as the variances decrease. The suggested method is illustrated with the repeatability of the process of the biological destruction of some medicine.

Authors:   V.A. Trapeznikov Institute of Control Sciences of the Russian Academy of Sciences, Kalanov Georgiy , Titov Nikolay ,   LTD “NVP MODEM”, Shibeko Victor ,   Sukhoi State Technical University of Gomel
Published: January 2022

The article investigates the combinatorial problem of the formation of coordinated work schedules, ensuring the continuous loading of the allocated labor resources for the construction of a group of wells. A parametric mathematical model of continuous scheduling, taking into account a number of restrictions on the organization of the well construction process, is proposed. The model is supplemented with a simple formula for calculating the time characteristics of the well construction depending on the drilling conditions and the drilling crew qualification. The universal nature of the basic model of continuous scheduling allows you to easily transform the model for many practical applications. A multi-criteria algorithm for finding the best planning options based on the methods of dynamic programming and aggregation of the initial planning task taking into account the flow rate of wells under construction is developed. For the selection of alternative solutions, a system of performance indicators and a number of criteria are proposed, taking into account not only the construction procedure and routes of drilling equipment, but also important economic factors, including the time risks of performing planned tasks. The novelty of the work lies in the fact that instead of the "manual" approach to the preparation of a single suitable calendar plan, a methodology for solving calendar planning problems is proposed, based on the development of adequate combinatorial search algorithms.
STABILITY ANALYSIS OF THE RATING AND CONTROL MECHANISM TO AGENT’S STRATEGIC BEHAVIOR (ON EXAMPLE OF THE RISK MANAGEMENT POLICY COORDINATION)
Authors:   Perm National Research Polytechnic University, Alekseev Alexander
Published: January 2022

The stability of the matrix rating and control mechanisms to the agent’s strategic behavior is investigated. The agents could to distort information about their capabilities and preferences to achieve their own purposes. It is shown that the results of complex assessment obtained using the additive-multiplicative approach of the mechanism based on the convolution matrix, the elements of which were determined using the matrix anonymous generalized mechanism, are resistant to the strategic behavior of agents, i.e. the agent's objective function, formalized as the difference between the complex estimate obtained by reporting the original convolution matrix and the complex estimate when the message is distorted, has a minimum. The task is considered on the example of the task of agreeing with the collegial management body a unified risk management policy of the organization in terms of creating a risk matrix that describes the response to the risks with all possible combinations of risk factors: the possibility (likelihood) of a risk event and consequences if it occurs (amount of risk). We consider a model example with three members of the board of directors, each of which has its own vision of the risk matrix, and shows the final risk map, which was obtained using the proposed approach.
THE METHOD OF AUTOMATICLY GENERATED EFFECTS OF EVENT-BASED GAME MECHANICS IN THE FRAMEWORK OF A CORPORATE E-LEARNING SYSTEM
Authors: Loginov Konstantin
Published: January 2022

The article is devoted to the problem of the lack of a flexible unified approach to the corporate e-learning systems implementation using game mechanics. The aim of the work is to develop a new method for automatically generated effects of event-based game mechanics. The proposed method is based on a formal model for describing event-based game mechanics and production rules. This approach allows us to consider the impact of event-based game mechanics as a control object, providing the ability to unify the rules for generating impacts for the entire class of event-based game mechanics. The article describes an information model of an e-learning management system that meets the xAPI (Experience API) standard specification and allows implementing proposed method for automatically generated effects of event-driven game mechanics. The proposed information model provides with ability for using a blended learning approach and mobile technologies. The article also highlights the specificities of the learning management system software implementation, designed on the basis of the proposed information model that meets the xAPI standard, and that implements the developed method for automatically generated effects of event-based game mechanics. It is proposed to consider the subcomponents of the Activity Provider component as separate microservices, the exchange of messages between each other by REST API interfaces. Information of user actions is also sent to the Learning Record Store (LRS) via REST APIs. The library of production rules is a separate component. The rules for automatically triggering the game mechanics’ effects are written using the extended Gherkin notation language. Every rule effect associated with a specific program function those implements dispatching events of actions of event-based game mechanics. Experiments and approbation of the proposed method of automatically generated effects of event-based game mechanics have proven the effectiveness of the proposed method. Results analysis of corporate training using the proposed solutions according to the four-level Kirkpatrick model showed that each of the four levels of this model for assessing effectiveness was successfully achieved.
ANALOGUE OF THE DISCRETE MAXIMUM PRINCIPLE AND THE NECESSARY OPTIMALITY CONDITION OF SINGULAR CONTROLS IN ONE TWO-PARAMETRIC DISCRETE OPTIMAL CONTROL PROBLEM
Authors:   Institute of Control Systems of NAS Azerbaijan, Mamedova Turkan
Published: January 2022

A two-stage (stepwise) optimal control problem for linear two-parameter systems with distributed control functions is considered. The aim of the work is to establish the necessary optimality condition under the assumption that the convexity of the set of admissible controls is satisfied and the connection condition is nonlinear. Using increments of the quality functional in the form of two-dimensional linear inhomogeneous systems of difference equations, a formula is obtained that allows one to obtain both a discrete analogue of the Pontryagin maximum principle and to study the case of its degeneration. A theorem is formulated that is an analogue of the discrete Pontryagin maximum principle for the problem under consideration. In the case of special controls, the discrete maximum principle degenerates and, therefore, becomes ineffective, including in the verification sense. Therefore, it is necessary to have new necessary conditions for optimality. A special, in the sense of the Pontryagin maximum principle, case of a discrete maximum condition, under which admissible controls are considered special, is studied. A necessary condition for optimality of singular controls is established.

The problem of constructing a mathematical model for assessing the competitiveness of the regions of the Russian Federation has been formulated and solved. For this, a structuring method based on hierarchical trees is proposed. Their leaves are statistical indicators of socio-economic activity according to official data. These indicators are combined using integral characteristics. An example of the analysis of networks of socio-economic indicators based on the construction of minimal sections of the Kolmogorov – Chapman equations for the “Innovation” indicator is given. To describe the leaf vertices of the indicator trees, it is proposed to use status functions that represent complex-valued functions. The proposed mathematical model represents a system of integrodifferential equations, including the status function for the integral indicator of the competitiveness of the region, functions for each of the integral indicators, polynomials that are obtained as a result of interpolation of statistical data, and management influences. The analysis of the obtained graphs of the normalized values of a number of static indicators, the assessment of trends is given. The possibility of using numerical methods of nonlinear dynamics based on status functions to take into account the cross-section and mutual influence of the parameters of the risks of competitiveness of the regions of the Russian Federation for use in automating decision support in social structures is shown.
EPÍLOGO - Trata de personas y migración
Authors: Gibajá, SAC Carmela
Published: January 2022

El llanto de Raquel no versa sobre su propio dolor personal, sino que en su grito queda recogido todo el sufrimiento de un conjunto de personas que están atenazadas y violadas en sus derechos fundamentales. El clamor de esta matriarca de Israel es, en primer lugar, un lamento colectivo. Este texto bíblico es una provocación y una invitación para transformar nuestra mirada y a ensancharla.

Published: January 2022

Neste relato de experiência, pretende-se apresentar uma prática pedagógica criada para a disciplina “Didáticas para o Ensino de Matemática” no curso de pedagogia do Instituto Singularidades. A elaboração de tal prática iniciou com a reflexão do ensino por competências e a análise de tais competências e respectivas habilidades propostas na Base Nacional Comum Curricular. Em seguida, fundamentou-se teoricamente a utilização de jogo como uma estratégia pedagógica, para então ser criado um jogo intitulado “Se movimentando com frações”, cujo público alvo são crianças do 5º ano do Ensino Fundamental. O referido jogo visa sistematizar o aprendizado de frações, especificamente a comparação entre elas. Foram elaboradas também algumas intervenções, de forma a propiciar uma reflexão dos estudantes sobre as possíveis jogadas, com objetivo de pensarem mais profundamente sobre o que aprenderam com o jogo.
O direito da criança com deficiência: profissional de apoio em sala de aula
Authors: Lopes de Souza Rafael , Mendes de Oliveira Andréia , Hatakeyama Viviane Vieira
Published: January 2022

A temática de educação inclusiva à pessoa com deficiência é caracterizada no direito de todos no processo escolar do ensino aprendizagem, por esta razão, apresenta-se: O direito da criança com deficiência: profissional de apoio em sala de aula. Indaga-se: toda criança com deficiência tem este direito de fato? A criança e o jovem com deficiência têm ganhado espaço dentro das escolas, um fator social que amplamente tem introduzido a necessidade de novas práticas pedagógicas para a inclusão de todas elas. Em maior ou menor escala, o Profissional de Apoio é um agente colaborador nesta trajetória, na busca constante de metodologias e autonomias que, somadas a políticas públicas, possam não só garantir, mas também questionar os aspectos inclusivos necessários.
Gestão Intercultural: Percepção de Gestores da Agroindústria do Sudoeste Paranaense

Este trabalho busca analisar a percepção de gestores em relação à gestão intercultural em organizações no setor da agroindústria na região Sudoeste do Estado do Paraná. Tal problematização centra-se na escassez de estudos em relação a gestão intercultural, especialmente ao se tratar da inserção de trabalhadores oriundos de outros países. A região Sudoeste do Estado do Paraná, foi palco de destino de trabalhadores haitianos que foram admitidos nas agroindústrias da região. Para tanto, realizou-se uma pesquisa descritiva, de caráter qualitativo, por meio da técnica de análise de conteúdo. Dessa análise emergiram, três categorias: reconhecimento do outro, diferença e identidade. Os resultados evidenciaram a ineficácia da comunicação, uma vez que, os trabalhadores migrantes não dominam a língua portuguesa, interferindo na interação com o ambiente de trabalho. Todavia, a gestão intercultural proporciona aprendizagens significativas relativo à diversidade, o reconhecimento do outro, assim como a interação entre culturas.
A relação prazer-sofrimento no contexto de trabalho de startups, à luz da psicodinâmica do trabalho

Published: January 2022

A pesquisa buscou compreender como se caracteriza a relação prazer-sofrimento, no contexto de trabalho em startups, à luz da Psicodinâmica do Trabalho (PDT). O referencial teórico foi composto pela conceituação de startups e seu desenvolvimento no mundo do trabalho, seguida da apresentação da lente teórica, a PDT, e suas macrodimensões. O método da pesquisa foi de cunho qualitativo, com coleta de dados através de cinco entrevistas semiestruturadas, com trabalhadores de três startups, as quais foram transcritas, categorizadas e analisadas a partir da técnica de Análise dos Núcleos de Sentido (ANS). Diante dos achados do estudo, conclui-se que o contexto laboral das startups possui, de forma mais representativa, vivências de prazer, pois o sofrimento não foi objetivamente identificado, mas sim diversas situações que podem promover sua posterior emergência, bem como aspectos limitantes que se colocam como barreiras ao prazer. O estudo contribui com uma incipiente e relevante combinação de construtos, proporcionando subsídios para diálogos teóricos futuros, além de contribuições práticas para os gestores das startups compreenderem seu contexto laboral e traçarem estratégias para a melhoria da relação homem-trabalho, estimulando seu potencial inovativo.
Fotojornalismo e imagem intolerável
Authors: Drigo Maria , Pagliarini de Souza Luciana Coutinho
Published: January 2022

Este artigo tem como tema relações entre imagens e jornalismo, com foco nas imagens fotojornalísticas que registram massacres, campos de refugiados, fugas em massa e outros horrores que permeiam o nosso planeta. Com o propósito de verificar se as imagens que provocam dor ou indignação são pertinentes ao fotojornalismo, apresentam-se aspectos da produção em fotojornalismo e o conceito de imagem intolerável, segundo Rancière, com análise da foto de Aylan Kurdi e de outras imagens que, em certa medida, reportam-se ao mesmo objeto ou referente. A relevância deste artigo está na possibilidade de repensar o senso comum então estabelecido para o fotojornalismo, o de exibir o intolerável na imagem.
