The article presents the results of a hygienic study conducted in the territory of the Primorsky Territory to assess the primary incidence of digestive system organs among the children of the Primorsky Territory. For the study, data on the recorded primary incidence for 18 years were analyzed. Mapping of the primary morbidity was carried out, the attributive risk of digestive diseases was calculated. The territorial distribution of statistically significant average annual levels of primary morbidity showed that children are more likely to suffer from gastritis and duodenitis, gastric ulcer and duodenal ulcer in the northern part of the region, where the highest incidence rates are recorded — these are rural areas. with an unstable economic situation and areas of the eastern coast of Primorye with the most unfavorable climatic conditions. The results of calculating the attributive risk show that children (0–7 years old) living in rural areas of the Primorsky Territory belong to the risk group for diseases of the digestive system. The identified territories are the least economically developed, with the absence of powerful sources of anthropogenic pollution of the population's habitat. The results obtained in this work should be taken into account when choosing and substantiating the indicators of the regional information fund for social and hygienic monitoring, when developing effective primary prevention measures and making managerial decisions at the regional level in the field of health care for children and children. adolescents in the Primorsky Territory.

presença de professores homens nos anos iniciais
Authors: Martins Fonseca Thomaz Spartacus , Ferrari Anderson
Published: July 2021

O cuidado e a feminização são duas características dos docentes que trabalham com crianças. Essas duas características acabam vindo à tona e sendo tensionadas com a presença de professores homens nos anos iniciais do Ensino Fundamental. Nosso propósito é problematizar essas tensões que relacionam gênero com docência a partir de uma pesquisa realizada com dois professores homens que lecionam nos anos iniciais. Foi a perspectiva pós-estruturalista, sob as influências das abordagens foucaultianas, que nos inspirou nas análises, considerando que somos resultados de discursos e de relações de saber-poder que vão construindo os gêneros e os seus lugares de pertencimento.

Authors: Souza Silveira Samara , Ferrari Anderson
Published: July 2021

Como o encontro com duas faxineiras negras na escola deu origem a um processo de repensar e colocar sob suspeita as formas de pensar e agir de uma professora branca e de classe média? Essa é a questão foco deste artigo que tem como objetivo a problematização das nossas formas de olhar e estar na escola. O convite é tomar as feministas negras e o arcabouço foucaultiano como perspectiva de análise sobre a interseccionalidade, os discursos, as experiências, as relações de saber-poder e a constituição dos sujeitos pelos atravessamentos de gênero, raça e classe. Foram esses encontros, não somente com as faxineiras negras, mas também com a leitura das feministas negras que foram capazes de (trans)formar a professora de História e convocar a escola para o trabalho com as relações de gênero, classe e raça, defendendo que as relações se constroem em todos os espaços escolares e não somente nas salas de aula.

Hérodote et la légende royale iranienne
Authors: Tourraix Alexandre
Published: July 2021

History, as founded by Herodotus, is neither pure inquiry, nor purely narrative process. To the main narrative, recounting and explaining the Persian Wars, Herodotus adds another history, that of the Median and Achaemenid Persian kings. He draws this part of his history, without knowing exactly what he does, from a number of narratives probably circulating in the Persian Empire, where they were part of the so-called “Royal Iranian Legend”, itself derived from the Indo-European ideology of sovereignty. Such an interpretation is by no means exclusive of any other.

Schon in der früharchaischen Kunst wird das Hermeszeichen in seiner endgültigen Form abgebildet. Seine Herkunft bleibt dennoch geheimnisvoll. Ais erster berichtet Hyginus über die Gestaltung des Stabes mit der Schlangenkrone, in einer wohlbekannten aitiologischen Erzählung. Kein antikes Kunstwerk hält den Augenblick der Entstehung fest. Erst die neuzeitliche Plastik stellt dar wie sich zwei Schlangen, irgendwo in arkadischer Landschaft, um den göttlichen Stab winden.
The strange case of Fyodor Dostoevsky and Robert Stevenson in the Victorian Age: A protest against the depersonalization
Authors: Kondratiev Alexander , Rudneva Olesуa , Tolstenko Andrew
Published: July 2021

In the article, the authors touch upon the problem of moral choice in the works of Dostoevsky and Stevenson. Comparative analysis showed that Dostoevsky's character strives more towards the ideal of all-humanity and to the deeds within the framework of Christian orthodoxy. In “The Double” Golyadkin who was rooted in the tradition of folk perception of the world, tries to preserve his moral look and attempts to reach a new level of self-determination. Stevenson created his own artistic version of the fate of the dual hero. The successful Dr. Henry Jekyll himself gave birth to Mr. Hyde to enjoy the fullness of sinful temptations, but life did not succumb to the presumptuous correction. The moral choice of the heroes of Dostoevsky and Stevenson, due to various reasons, to reach the heights of success and sink to the very bottom, testifies to the futility of claims to spiritual emasculation of a person and depersonalization in the bureaucratic world.

Authors: Ríos-Cuesta Wilmer
Published: July 2021

Diversos estudios han comentado la importancia de la argumentación en la construcción de conocimiento matemático y las implicaciones en el desarrollo de competencias. Estos estudios han centrado su mirada en el análisis de la actividad discursiva en el aula en torno a la construcción individual y colectiva de argumentos válidos. Otros, en cambio, en la cognición que desarrollan los estudiantes en las interacciones en clase y tratan de acercarlos a los procesos de prueba mediante la presentación de argumentos deductivos. Sin embargo, son diversas las posturas sobre lo que se entiende como argumentación, al punto que algunos conciben la prueba como una forma particular de argumentación. En este estudio se presenta un análisis documental que resulta útil para futuras investigaciones en educación matemática al develar algunas posturas encontradas en investigaciones sobre argumentación, así como algunos marcos teóricos predominantes para analizar los actos de habla, de modo que les permita a los investigadores posicionarse de acuerdo con el tipo de investigación que desarrollen. Se destaca el uso del modelo de Toulmin para tipificar argumentos y la propuesta del modelo ck¢ para indagar en los conocimientos que movilizan los estudiantes en los procesos de argumentación.

Aplikasi website menjadi salah satu komponen penting bagi sebuah perusahaan. Setiap aplikasi website terdaftar ke sebuah alamat domain untuk mengakses aplikasi tersebut. Sebuah website biasanya memiliki sebuah halaman yang bersifat umum dan sebuah halaman private yang digunakan untuk pengelolaan data yang ditampilkan. Tetapi hal ini membuat developed time menjadi lama karena developer perlu membuat dua buah muka website. Laravel frameworks memungkinkan sebuah aplikasi menerima request dari lebih dari 1 domain. Penulis membuat sebuah aplikasi website yang dapat menerima request dari banyak domain, dan memungkinkan pengelolaan semua data hanya menggunakan sebuah muka aplikasi website. Pengujian membuktikan aplikasi yang dibangun dapat mengurangi development time.

The paper discusses previous studies on the effect of fatigue among flight crews and their effect on airline businesses. Fatigue is a major concern in flight operations as many reports were issued on this problem among flight crew. The long flight duration requires them to travel several time zones, which leads to fatigue. Furthermore, the change of time zones could also lead to the occurrence of jet lag and subsequently causes fatigue too. Fatigue can occur during and after the travelling period, and it takes a while to recover from it. This study aims to observe the effects of fatigue experienced by flight crew. The results show that fatigue causes many health problems such as an increase in cancer risk, depression, mental illness and miscarriage. Additionally, fatigue reduces one's work productivity as working in a tired state reduces work performance. Furthermore, fatigue also leads to other problems such as anger, anxiety, stress and job dissatisfaction. With the studies conducted on the issue of fatigue, airlines should take appropriate actions to minimise or solve the problem to ensure that fatigue problem will not affect flight crew performance and the airline business.

Published: July 2021

Investigations of the thickness and optical characteristics of thin SiO2 films obtained by one-, two-, or three-stage rapid thermal processing (RTP) at atmospheric pressure, pulses of 6, 12, and 20 s duration have been carried out. To obtain thin SiO2 films by the RTP method, N-type:Ph 4.5 Оhm/□ (100) silicon wafers were used as initial samples. The samples were preliminarily oxidized at 1000 °C of the obtained wet oxygen (SiO2 d = 100 nm), then the silicon oxide was completely removed in a solution of hydrofluoric acid, after which the wafers were subjected to chemical cleaning using the Radio Corporation of America (RCA) technology. Oxidation in a stationary oxygen atmosphere was carried out in one or two stages by heating the plates with a light pulse of different power up to maximum temperatures of 1035 – 1250 °C, as well as a three-stage process, where the final stage was annealing in a nitrogen atmosphere or in a forming gas (N2 97% + H2 3%). The characteristics of SiO2-Si barrier structures nitrided in N2, obtained by the RTP process by light fluxes with pulses of a second duration, were studied to improve the electrophysical parameters of gate oxides by the RTP method. It is of interest for integrated circuits (ICS) with a high density of the active regions of devices.
Image processing method based on aerospace monitoring
Authors: Mitsiukhin A. I. , Pikirenya I. I.
Published: July 2021

The paper considers a digital image processing method that provides efficient transmission, redistribution and storage of aerospace environmental monitoring videographic information. The requirement to increase the monitoring efficiency, if necessary, to carry out regular monitoring of changes in the image field of the observed object is especially relevant when describing spatially aligned sets of images obtained after multi-zone, multi-time and multi-polarization shooting. In many remote sensing applications, the processing efficiency reflects the degree of reduction in the volume of transmitted, described, analyzed and stored videographic information. The computational processing of digital images based on the coordinate survey scheme is presented. The method can be used to perform the procedure for decoding images in order to solve the problem of classifying objects of interest, analyzing images. Such characteristics of binary objects as a spatial boundary and a contour were used as deciphering signs. These features make it possible to describe the shape of an object, its geometric parameters and search for images with specific spatial structures. The processing method is realized by executing efficient algorithms for coding an image on a discrete grid by means of a chain code and spectral coding based on the fast discrete Hartley transform. The result of processing comes down to minimizing the number of such basic computational operations as multiplication, addition, transferring, as well as reducing the time and capacitive complexity of the program, and reducing the redundancy of the initial data. An example of an effective representation and description of a segmented image of an object is given. The proposed method makes it possible to expand the technical capabilities of more efficient transmission and processing of images for solving problems in the field of remote sensing.

Authors: Shcherbina N. V.
Published: July 2021

Biofeedback based on electrodermal activity of the skin is used as a method for optimizing the functional state of drivers and assistant drivers of locomotive crews. High-quality inter-trip rest of locomotive crew drivers ensures the preservation of health, labor protection and higher indicators of professionally important psychophysiological qualities necessary for the successful performance of locomotive management activities. The purpose of this work is to determine the nature of the relationship between the relaxation abilities of locomotive crew drivers and their professionally important psychophysiological and personal qualities. The experiment was conducted on the basis of the office of the psychological service of the Motor Car depot in Minsk. A personal computer and the NeuroDog hardware and software complex were used as the equipment for the biofeedback training. A factor analysis of the primary empirical data of subjects who successfully developed the relaxation skill was performed. Factor analysis was carried out using the principal component method and the Varimax method available in the Statistica 10.0 package. The results of the analysis allowed us to determine the structure of psychophysiological and personal qualities of locomotive crew drivers, as well as the degree of their influence on the successful development of relaxation skills. The results obtained will later be used to develop a methodology for training drivers in relaxation skills in accordance with their individual characteristics and algorithms for its implementation in the context of the UPDK-MK hardware and software complex, used by the psychological service of the Belarusian railway to monitor the current state of functional systems of locomotive crew drivers.
Research of the process of obtaining capillary-porous materials from metal powders for heat pipes

Published: July 2021

Heat pipes are designed to effective removing heat from heating elements and reducing the temperature of various devices. Heat pipes with capillary porous structures are designed to operate under conditions of unfavorable gravity forces. Their main advantages are their high heat transfer capacity, as well as the ability to retain the coolant in a capillary-porous structure under dynamic power loads. The purpose of this work is to study the process of obtaining capillary-porous materials from metal powders for heat pipes with increased efficiency of using the vibration molding method. The article substantiates the relevance of creating heat pipes from metal powders. The information about the influence of the contact angle, surface tension and capillary pressure on the heat transfer capacity of a heat pipe is provided. It is shown that for the efficient operation of the heat pipe it is necessary to create such a capillary structure of the porous material, which could simultaneously provide a high speed of movement of the coolant and its rise to a given height. The above requirements can be satisfied by creating a capillary structure using powder metallurgy methods by optimizing the distribution of pore sizes. In this case, the most promising method seems to be the method of molding when applying a vibration to a mold with a powder. It is possible to obtain the required pore distribution in this way by choosing the correct particle size, shape and vibration parameters. This makes it possible to ensure the packing of particles in size, which affects their packing density, pore size, tortuosity and length of pore channels. The distribution of the maximum pore sizes over the thickness of the samples obtained from powders of various granulometric composition with the use of vibration has been investigated. As a result, a process was developed for obtaining capillary structures by the method of vibration molding of metal powders, depending on the size of the powder particles, the amplitude and frequency of vibration. It is shown that this method can provide a given pore distribution of the capillary structure for heat pipes, which makes it possible to increase their heat transfer capacity.
Division of images into areas of local extrema with a monotonic change in pixel brightness
Authors: Nguyen A. T. , Tsviatkou V. Yu.
Published: July 2021

In this paper, the problem of segmentation of halftone images is considered, in which areas of local maxima and minima (extrema) are distinguished with a monotonic change in the brightness of pixels from local extrema to the boundaries of areas. To solve this problem, a mathematical model is proposed and a segmentation algorithm is developed on the basis of counter-wave growing of local extremum regions. The developed algorithm differs from the known segmentation algorithms by using a set of brightness thresholds (by the number of regions), varying by one in each cycle, starting from the values of local extrema, taking into account the increase or decrease in brightness to select adjacent pixels that are attached to the regions formed from these local extrema. The algorithm provides a greater deviation of pixel brightness from the average value within the region compared to known segmentation algorithms. This does not allow evaluating its efficiency using known indicators based on the variance of the brightness within the region. In this regard, estimates of the monotonicity of changes in the brightness of regions are proposed based on a) the shortest distances from each pixel of the region to the corresponding local extremum along the routes determined by the maximum increase (for the region of the local maximum) or decrease (for the region of the local minimum) the brightness of pixels and b) taking into account the number pixels that break the monotony of the segment brightness change. Using these estimates, it is shown that the proposed algorithm provides segmentation of artificial and natural grayscale images with a monotonic change in the brightness of pixels in the areas of local extrema. These properties allow us to consider the developed algorithm as a basis for the selection of texels, spots, low-contrast objects in images.

Це виявляється у здатності особистості до мотивованої саморегуляції ефективної поведінки, збереження самоідентичності, забезпечення особистісного потенціалу, організації умов життя та реалізації особистісного зростання.

Визначено психологічний механізм формування особистісної зрілості через закріплення в індивіді системи здібностей, що функціонують у певній діяльності, яка забезпечує оволодіння предметами матеріальної і духовної культури, в яких втілено людські здібності. Здійснено теоретико-методологічний аналіз категорії здібності з точки зору діалектики загального, особливого та одиничного у проявах психічного. Визначено психологічну природу особистісної зрілості в широкому науково-теоретичному сенсі (на рівні загального), її специфічні характеристики в контексті актуальних ситуацій життєдіяльності (на рівні особливого) та закономірності формування індивідуальної конфігурації в межах психологічного простору особистості (на рівні одиничного).
ИМПЛИЦИТНЫЕ ТЕОРИИ ЛИЧНОСТИ УЧЕНИКОВ, СУЩЕСТВУЮЩИХ В СОЗНАНИИ ПЕДАГОГОВ НАЧАЛЬНЫХ КЛАССОВ
Authors: Былинская Наталия
Published: July 2021

В настоящей статье излагаются результаты исследования имплицитных теорий личности (ИТЛ) школьников у педагогов начальных классов. Моделирование имплицитных теорий личности различных типов учащихся (нормального, трудного, одаренного и развивающегося) у учителей младших классов, осуществленное посредством метода семантического дифференциала, показало их одинаковую когнитивную сложность для ученика нормального, проблемного, одаренного (пять ортогональных категорий). ИТЛ ученика развивающегося проще по своей структуре (четыре категории), что свидетельствует о меньшей знакомости для учителей данного типа учащихся. Общими категориями, опосредующими понимание учителями начальных классов различных типов учеников, являются: «ученический нонконформизм», «прилежание», «креативный лидер», «рациональный самоконтроль». Специфической категорией в ИТЛ проблемного ученика выступает конструкт «коммуникативное поведение», а в ИТЛ одаренного ученика – это конструкты «неординарность», «благополучная одаренность» и «проблемная одаренность». Выявленная структура и содержание имплицитных теорий личности школьников свидетельствуют о недостаточной дифференциации знаний о личности различных типов учащихся в педагогическом сознании.
ПЕРЦЕПТИВНЫЕ ДЕЙСТВИЯ ПОДРОСТКОВ С ПРЕДМЕТАМИ ВАРИАТИВНОЙ ФОРМЫ И ИГРОВАЯ ЗАВИСИМОСТЬ
Authors: Северин Алексей
Published: July 2021

В статье анализируется проблема тактильного восприятия предметов с вариативной формой. Рассмотрены два теоретических подхода к исследованию восприятия упругости. Автором установлено, что при блокировке зрительного тактильного звена модели перцептивного действия с предметом вариативной формы нарушается работа механизма перцептивного действия, значительно снижается точность перцептивных действий подростков-геймеров с предметом вариативной формы. В связи с этим становится важным в теоретическом и прикладном планах изучение зрительного, тактильного восприятия предметов вариативной формы подростками. Именно в подростковом возрасте в связи с его противоречивостью и переходным характером протекания, а также в виду неблагоприятных обстоятельств (например, появлению у них компьютерной игровой зависимости) данный навык может деформироваться. Поэтому становится важным изучение того, как именно подростки воспринимают предметы вариативной формы. На основе этого сложного вида восприятия у них происходит становление других психических процессов (памяти, мышления). Перцептивные действия выступают для подростков как условие и предпосылка успешности их общественной социализации, подготовки к выбору будущей профессии.

Результаты исследования показали, что при блокировке и разблокировке разных звеньев (глаза, руки, рассогласования) работа перцептивного действия с предметом вариативной формы и точность шкалы упругости у обычных подростков существенно отличается от подростков- геймеров. У геймеров заметно снижается точность перцептивных действий и в большей степени деформируется восприятие предметов вариативной формы.
КОНЦЕПТУАЛЬНІ ПІДХОДИ ДО ВИВЧЕННЯ ПРОБЛЕМИ НОРМАТИВНОСТІ У ПСИХОЛОГІЧНІЙ НАУЦІ
Authors: Хомич Іванна

У положеннях наукової статті автор аналізує концептуальні підходи до вивчення проблеми нормативності у вітчизняній і зарубіжній психологічній науці та рівень дослідженості вказаної проблеми, зокрема, в аспекті психологічного аналізу нормативної поведінки особистості. Автор також здійснює уточнення та подальшу конкретизацію понятійного апарату дослідження, який включає дефініції базових категорій та понять роботи. В рамках статті здійснено аналіз характеру конгруентних зв’язків між нормативністю та нормою. В якості сутнісних атрибутивних характеристик норми, змістовно релевантних предмету дослідження – нормативній поведінці, автор виокремлює: об’єктивність норми, тобто незалежність її від індивідуальної свідомості; низький ступінь усвідомлення; здатність здійснювати регулюючий вплив на поведінку; здатність організовувати поведінку в певному напрямку, тобто виступати в якості формуючого орієнтиру дії; властивість прогнозувати кінцевий результат дій.
CAUSE-RELATED MARKETING AND CAUSE SPONSORSHIP’S COMPANY-CAUSE FIT AND eWOM: SPREADING CSR ON FACEBOOK
Authors: Pangan Ronnie , Shim Jaehak
Published: July 2021

Businesses should utilize Corporate Social Responsibility (CSR) marketing communications to show genuine support for stakeholders affected by the Covid19 pandemic. This study focuses on two forms of CSR marketing communications: cause-related marketing (CRM) and cause sponsorship (CS). This research would look into how CRM and CS’s company cause fit will affect eWOM (electronic word-of-mouth), a type of consumer response. A survey-based within-subjects trial of CRM and CS x 2 company-cause fit will be conducted on active Facebook users aged 18 to 64 years old. Ten (10) pre-selected firms from the Philippines' Top 30 Businesses were selected. These companies posted both CRM and CS Facebook messages. The CRM posts will be shown to half of the sample size (N=272), while the CS posts will be shown to the other half (N=272) and graded via a questionnaire. The research concluded that there were positive relationships between CRM and CS’s company-cause fit and eWOM. Between the two, CRM had a greater effect on eWOM as compared to CS. This was also evident in the models. The higher the company-cause fit, the higher the eWOM response. The suggestion to companies was to concentrate on CRM FB posts with the high company-cause fit so that the occurrence of eWOM would be higher especially during periods of crisis like the Covid19 pandemic. For future researchers, other forms of CSR marketing communications and consumer responses may be studied to further increase the effectiveness of Facebook CSR posts.
THE EFFECT OF MARKETING ETHICS AS A MODERATOR ON THE RELATIONSHIP BETWEEN CUSTOMER ORIENTATION AND SMES PERFORMANCE IN SAUDI ARABIA

Recent literature has demonstrated the importance of consumer orientation (CO) for small and medium-sized enterprises (SMEs); however, doubts persist about how CO can improve SMEs performance due to its ambiguity. We examine the marketing ethics (ME) that govern the relationship between COs and SMEs. A proposed model was empirically tested using a structural equation model (SEM) on 408 manufacturing SMEs in Saudi Arabia. The findings indicate that CO has a positive effect on the performance of SMEs and, more importantly, that this effect is indirect because ME fully moderates it. These findings indicate that CO improves performance when firms invest in marketing ethics development. While consumer orientation is critical, it may not be enough to boost performance if the firm is unable to adhere to marketing ethics practices.
Estado, institucionalidade e a interiorização da economia política na produção do indivíduo
Authors: Santos Thiago Andrade dos
Published: July 2021

Este estudo de natureza teórica objetiva refletir acerca do modo como a economia política produz e reproduz a sociedade e, para isso, precisa reproduzir o indivíduo. Evidencia-se o papel assumido pelo Estado, ou por qualquer forma de institucionalidade, na reprodução da sociedade. Os diversos enfrentamentos próprios do campo da política são, destarte, absorvidos, obscurecidos, ou apaziguados por esse Estado e sua arte de governar, que, com sua pretensa neutralidade e razão consensual, atua em função da anulação dos contrapoderes e de demais resistências. No modo de produção capitalista o Estado, atuando em função do processo de acumulação dos capitais, fortalece o poder do capital sobre o trabalho em tempos em que este último, tendencialmente, é expulso do processo produtivo. Os aportes teóricos aos quais se recorre nesta reflexão, embora distintos entre si, caminham no mesmo sentido, mas em paralelo, tocando-se alguns pontos. Ambos revelam que o poder hegemônico, em suas diversas formas de manifestação, sempre objetiva a produção de sociedades a sua imagem e semelhança.
The Reflection on the Human Nature and the Power in the Constitution of the Republic of Poland of 1997 from the Legal-Constitutional Research Perspective
Authors: Litwin Tomasz
Published: July 2021

RESEARCH OBJECTIVE: The main research aim of the article is the analysis of the relations between the conception of the human nature and the main purposes of the power in the rules of the Constitution of Poland.

THE RESEARCH PROBLEM AND METHODS: The research problem of the article is how the constitutional conception of the human nature influences the conception of power and its purposes expressed in the Constitution. The article presents the legal-constitutional research perspective and is based on various methods of interpretation of the constitutional rules.

THE PROCESS OF ARGUMENTATION: The article analyses the constitutional conceptions of the human nature, power and its purposes, as well as their mutual relations.

RESEARCH RESULTS: It seems that the constitutional conception of the human nature has only partial influence on the rules of the constitution describing the power and its purposes.

CONCLUSIONS, INNOVATIONS AND RECOMMENDATIONS: The conception expressed in the preamble of the Constitution describing the Polish citizens as accepting such fundamental and universal values as truth, justice, good and beauty is inadequate. It should be removed and these values could be introduced to art. 8 along with such value as “wisdom”, as the set of fundamental values protected by the Constitution.
