Authors: Гулов Владимир Павлович , Хвостов Виктор Анатольевич , Косолапов Владимир Петрович , Сыч Галина Владимировна
Published: April 2021

Проведен анализ моделей управления доступа используемых в настоящее время в системах защиты информации. На основе анализа достоинств и недостатков дискреционной, полномочной и ролевой моделей при осуществлении доступа мобильных систем субъектов с различными потребностями и ролями к иерархически организованным информационным объектам медицинских информационных систем предложено использовать управление доступом на основе тематическо - иерархической политики. На основе анализа организационной структуры медицинской организации и типовых модулей медицинских информационных систем, имеющих иерархическую структуру при которой тематика объекта доступа определяется тематическими узлами классификатора с автоматическим распространением на объекты классификации всех соответствующих подчиненных тематических узлов, субъектам доступа предоставляются права на доступ к объектам, тематика которых соответствует одному или нескольким узлам классификатора с автоматическим распространением прав работы на документы с тематикой соответствующих подчиненных узлов. Предложены методы формирования тематических решеток, обеспечивающие контроль безопасности информационных потоков. В статье предлагаются методы задания матрицы достижимости по чтению, записи и выполнению разных субъектов доступа к объектам доступа с монорубрицированной и мультирубрицированной иерархической тематической классификацией

The analysis of access control models currently used in information security systems is carried out. Based on the analysis of the advantages and disadvantages of discretionary, authoritative and role models when accessing mobile systems of subjects with different needs and roles to information objects of medical information systems, it is proposed to use access control based on a thematic hierarchical policy. Based on the analysis of the organizational structure of a medical institution and typical MIS modules, having a hierarchical structure in which the subject of the access object is determined by the thematic nodes of the classifier with automatic distribution to the classification objects of all corresponding subordinate thematic nodes and access subjects are granted access rights to objects whose subject matter corresponds to one or several to the nodes of the classifier with automatic distribution of the rights to work on documents with the subject of the corresponding subordinate nodes, methods for the formation of thematic lattices are proposed to ensure the security control of information flows. The article discusses methods for setting the reach ability matrix for reading, writing and executing different subjects of access to access objects with monorubric and multi-categorized hierarchical thematic classification

НАСЕЛЕННЫЕ ПУНКТЫ РАВНИННОЙ ЧЕЧНИ В 1824-1834 гг.
Authors: Осмаев А.Д.
Published: April 2021

Изучение истории предполагает не только установление фактов, связанных с тем или иным событием, но и, по возможности, реконструкцию названий и местоположения населенных пунктов, существовавших в тот период, определения численности проживавшего в них населения и к какому обществу чеченского народа оно относится. Задача тем более важна, что значительная часть этих аулов и сел так и не возродилась после неоднократного уничтожения и в настоящее время не существует. Не менее важной задачей нам представляется установление и сохранение имен активных участников событий, которыми, к сожалению, история Чечни в данное время не изобилует. Задачи эти нужно решать комплексно, изучая документы того времени, топонимию современных населённых пунктов и прилегающих к ним территорий, предания, легенды, семейные хроники.
СЕМЬЯ И СЕМЕЙНЫЙ БЫТ ЧЕЧЕНЦЕВ В 20-30-е ГОДЫ XX ВЕКА
Authors: Абдулвахабова Б.Б.-А. , Гелаева З.А.
Published: April 2021

В статье рассматриваются изменения, связанные с семьей и семейным бытом чеченцев в 20-30-е годы XX, в эпоху социалистических «модернизаций» в стране. Вековые традиционные формы, являющиеся основой семейного быта чеченского общества, в период модернизационных процессов постепенно разрушались. В период советской власти, особенно в 20-30-е годы XX столетия, эти основы претерпели кардинальные изменения. Сегодня, в постоянно меняющемся мире, где семье, семейным традициям отводится второстепенная роль, актуальным представляется изучение, анализ трансформаций, которые происходили в чеченских семьях, в семейном быте, роли женщины в обществе и семье в прошлом и настоящем. Несмотря на то, что данная тема освещалась в историко-этнографических исследованиях, пробелов достаточно. Актуальность избранной проблемы и заключается в том, чтобы объективно изучить и извлечь уроки из прошлого: содействовать сохранению ценностей, на которых развивалось чеченское общество, так как именно эти основы помогали чеченскому народу сохранить себя как социум в двадцатом столетии в процессе репрессий и страшных военных катаклизмов.

СОЛДАТСКИЙ ОРДЕН СЛАВЫ
Authors: Цуцулаева С.С.
Published: April 2021

В данной статье автор провел тщательную работу по выявлению участников Великой Отечественной войны из числа чеченцев, удостоенных ордена Славы различных степеней. Эта статья – дань уважения памяти тех, кто, не щадя своей жизни, сражался на полях Великой Отечественной войны, приближая заветный День Победы. Среди чеченцев немало фронтовиков-героев. Об одних написано и сказано много, другие скромно отмалчивались, не видя в том ничего героического. Однако мы должны понимать, что нельзя допустить, чтобы их славный военный путь был предан забвению. Нам необходимо выявить каждого воина-земляка, чтобы тем самым навсегда отбить охоту отдельным злопыхателям клеветать на наше славное прошлое, преступно обвиняя в пособничестве немцам. Имена героев, представленных в статье, - доказательство необоснованности таких обвинений.
ИЗ ИСТОРИИ ПАРАФИНОВОГО ПРОИЗВОДСТВА В ГРОЗНОМ
Authors: Эльбуздукаева Т.У. , Солтамурадов М.Д. , Гайтамирова С.А.
Published: April 2021

В статье рассматривается история парафинового производства в Грозном в 1920-х годах. Это стало возможным благодаря развитию нефтеперерабатывающей и нефтехимической промышленности, а также стало следствием политики индустриализации. Первый период после национализации рационализация эксплуатации промыслов шла под знаком количественного увеличения насосных скважин. Начиная со второй половины 1926-27 гг., рационализаторские мероприятия были направлены на целесообразное и экономически выгодное использование глубоких насосов. По мере расширения выхода грозненских нефтепродуктов на экспорт, направление переработки получило бензинокеросиновый характер. Основной задачей переработки становилось увеличение получения светлых нефтепродуктов в пределах тех же процессов первичной переработки. Особняком стояло создание парафинового производства. Парафиновый завод в Грозном начал свою работу с октября 1927 года. В своей работе завод был неразрывно связан с 14-кубовой масляной батареей, являющейся первичным производственным звеном в общей системе выработки парафина, поставляя для парафинового завода необходимый для его работы полуфабрикат.

Authors: Джамалдинов С.А.
Published: April 2021

Статья посвящена актуальным вопросам официального обнародования нормативных правовых актов государственных органов Чеченской Республики. Своевременное и полное информирование населения республики о нормотворческой деятельности уполномоченных органов является обязательным и необходимым условием возникновения у них соответствующих прав и обязанностей, а также способствует эффективной защите их прав. Результаты исследования приводят к выводу о том, что в Чеченской Республике предусмотрено официальное опубликование нормативных правовых актов в периодических печатных изданиях и в электронных средствах массовой информации, что является своевременным и прогрессивным решением. Между тем, в теоретической и практической плоскости неизбежно возникают коллизионные вопросы, связанные с возможными разночтениями в документах, опубликованных в печатных и электронных ресурсах, что требует дополнительных законодательных усилий по их решению.
СОВРЕМЕННЫЕ ТЕХНОЛОГИИ МОДЕЛИРОВАНИЯ СОДЕРЖАНИЯ УРОКА ФИЗИЧЕСКОЙ КУЛЬТУРЫ
Authors: Хамсуев Р.Н. , Умаров А.А.-К.
Published: April 2021

Традиционные проблемы в области школьного образования обычно связаны с проблемами воспроизводства неравенства, отсева, адаптации, доступа и качества, языка обучения и межличностного обмена, расстройств, учебных материалов, практики преподавания и успеваемости. Они часто обращаются к этим вопросам на стыке двух основных измерений обучения: когнитивной и интеллектуальной деятельности субъекта, с одной стороны, и социального и культурного измерения, с другой.
Уроки физической культуры строятся в соответствии с общими педагогическими принципами и должны решать образовательные, оздоровительные и воспитательные задачи. Образовательные задачи решаются путем предоставления учащимся необходимых знаний, умений и навыков по выполнению физических упражнений и, что самое главное, использования их в повседневной жизни и в процессе самосовершенствования.

ВОСПИТАНИЕ ГИБКОСТИ С ИСПОЛЬЗОВАНИЕМ УПРАЖНЕНИЙ ЦИКЛИЧЕСКОГО ХАРАКТЕРА
Authors: Исханов А.С.
Published: April 2021

Гибкость – это такое физическое качество, которое позволяет выполнять различные виды двигательных действий с максимальной амплитудой. Во многих видах спорта двигательные действия носят циклический характер, причем амплитуда их выполнения зависит от анатомического строения суставов, а также степени растяжения мышц и связок. Для занятий спортивными играми в физическом воспитании молодежи требуются достаточно высокие показатели подвижности суставов. Следует подчеркнуть, что в игровых видах спорта наряду с ситуативными движениями спортсмены выполняют и циклические двигательные акты, которые в основном проявляются через призму перемещений спортсмена по площадке. В этой связи перед специалистами постоянно стоит вопрос поиска наиболее рациональных средств воспитания гибкости с помощью циклических упражнений. Одним из таких средств являются упражнения на растяжение (стретчинг), в процессе выполнения которых двигательные действия могут повторяться неоднократно – циклично.
Permasalahan dalam Penerapan Mekanisme Pasar Perspektif Islam
Authors: Wahyuni Tri
Published: April 2021

The market is a place for economic activity where economic activities take place naturally so that the rules of the game occur naturally. So according to Islamic economics the market mechanism can occur naturally from the supply and demand side as it should. Furthermore, in terms of the market mechanism of the Islamic economic perspective, in principle, it rejects the existence of a price intervention if price changes occur because the market mechanism is reasonable. However, the market here requires morality, among others: fair competition, honesty, transparency and justice. If these values ​​have been enforced, there is no reason to reject market prices. And if there is a deviation, the state's obligation to regulate it is for the benefit of the people.

In the present paper, we investigate a generalized differential mixed quasi-variational inequality consisting of a system of an ordinary differential equation and a generalized mixed quasi-variational inequality. By using an important result concerning the measurable selection, we prove the existence of Caratheodory weak solution to ´ the generalized differential mixed quasi-variational inequality. Then, with the existence result, we establish two stability results for the generalized differential mixed quasi-variational inequality under different conditions, i.e., upper semicontinuity and lower semicontinuity of the Caratheodory weak solution with respect to the ´ parameter, which is a perturbation of some mappings in the generalized mixed quasi-variational inequality.

In the present work, we discuss the existence of mild solutions for the initial value problem of fractional evolution equation of the form where C Dσ t denotes the Caputo fractional derivative of order σ ∈ (0, 1), −A : D(A) ⊂ X → X generates a positive C0-semigroup T(t)(t ≥ 0) of uniformly bounded linear operator in X, b > 0 is a constant, f is a given functions. For this, we use the concept of measure of noncompactness in partially ordered Banach spaces whose positive cone K is normal, and establish some basic fixed point results under the said concepts. In addition, we relaxed the conditions of boundedness, closedness and convexity of the set at the expense that the operator is monotone and bounded. We also supply some new coupled fixed point results via MNC. To justify the result, we prove an illustrative example that rational of the abstract results for fractional parabolic equations.

Are Shocks to Tourist Arrivals in Morocco Permanent or Temporary?
Authors: El Menyari Younesse
Published: April 2021

The main goal of this article is to examine whether shocks had a permanent or temporary effect on international tourist arrivals in Morocco for its top 8 source countries. For this purpose, we apply the linearity test and the linear and nonlinear unit root tests. The results show that the series with linear characteristics are tourist arrivals from the UK and US and those with nonlinear characteristics are tourist arrivals from Belgium, France, Spain, Italy, Netherlands, and Germany. The unit root tests reject the null hypothesis of a nonstationarity in tourist arrivals from all countries except Germany. The implication of these findings is that the shocks had a temporary effect on tourism arrivals from seven markets to Morocco. Therefore, Morocco's tourism sector is a sustainable industry as external shocks have not had long-term disruption in the flow of tourist arrivals.
Gladiis ET Clypeis: Travel Motives Towards an Improvement Of Quality of Life When Visiting a Military Expo
Authors: Venter Dewald , Kruger Stefan , Uysal Muzzo
Published: April 2021

The African Aerospace and Defence military expo is held biannually in South Africa and is classified as the biggest military expo (event) on the African continent. This study sought to determine the effects that travel motives and life domains have on visitors' quality of life. The
study followed a convenience sampling technique, with fieldworkers administrating the measuring battery to visitors at the African Aerospace and Defence military expo. Data were gathered from 293 visitors regarding their travel motives, life domains, life domains overall, and quality of life.
A structural equation modeling analysis indicated a positive linear relationship between the visitors' travel motives, life domains (social life, leisure life, and self-life), life domains overall, and quality of life; all of which attained good composite reliabilities. The findings indicate
that travel motives have an influence on visitors' life domains, positive and negative, relevant to their perceived importance. Overall, a visit to this military expo had a positive effect on visitors' quality of life. Managerial recommendations include maximizing the uniqueness and novelty
of the event, which cannot be done generically. Digital marketing should be aimed at certain lifestyle aspects that are most appealing to visitors, such as social, leisure, or military life. The approach would likely appeal to the higher order needs of potential visitors, which could contribute
to their overall life satisfaction. This research contributes to the literature and methodology in tourism, positive psychology, and quality of life.
Overtourism: Residents' Perceived Impacts of Tourism Saturation
Authors: Berselli Cristiane , Pereira Lucimari Acosta , Pereira Tércio , Limberger Pablo Flôres
Published: April 2021

Tourism is a dynamic industry due to changes in the consumer market, and its constant development impacts the host community. Although the adverse outcomes of tourism are not a new phenomenon, new dynamics make this issue of ongoing importance. Governments see the activity primarily
as fostering economic development in developing countries with little concern about possible overtourism. This article aims to identify which indicators influence residents' perceptions of tourist saturation as an indication of overtourism. These perceptions are examined as a multidimensional
construct, comprised of several indicators, namely environmental, cultural, behavioral, public services, benefits, and economic costs. The proposed model is assessed with a sample of 477 residents in coastal destinations of Santa Catarina, Brazil. The results show that the perception of excessive
numbers of tourists is increased by environmental indicators, economic costs, and behavioral indicators. These indicators contribute to a greater perception of overtourism. In contrast, the indicators of economic benefits and public services show a negative relationship with the perception
of overtourism. This research indicates that when the population realizes the economic benefits and has access to quality public services, the perception of overtourism is lower. The findings contribute to the literature on overtourism in certain destinations.
Evaluation System of Green Tourism Industry
Authors: Wei Min , Wei Haixiang , Huang Haiyu
Published: April 2021

This study contributes to understanding the dynamic evolution process of green tourism industry, for which the evaluation system is constructed combining stakeholder theory with the characteristic of green tourism industry. Data from Mainland China from 2011 to 2017 are used to build the evaluation system of green tourism industry. The data are also analyzed comprehensively by applying entropy weighted TOPSIS and geospatial visualization. Following a horizontal comparison between provinces in Mainland China and a longitudinal comparison of the development history of these provinces, results show that the development of green tourism presents regional differences. Developed areas in the eastern region are superior to that in central and western regions in Mainland China. Interestingly, the relationship between green tourism development and the economy is non-linear. Green tourism resources, traffic accessibility, macroeconomic development level, and tourists’ characteristics will affect the development potential of green tourism. Ultimately, this study brings managerial implications to the development of green tourism.

Glial tumors, in particular those composed of astrocytes, are the most common group of primary brain tumors. The most common glial tumor is astrocytoma. The biology of glial tumors was routinely studied on immortalized cell lines. However, multiple passages result in a loss of cellular heterogeneity. Therefore, more and more scientific laboratories in their research are beginning to use primary cell lines obtained directly from the patient’s native postoperative material. The question of the timing of the genetic stability of primary cell lines remains open. A special type of genetic instability is microsatellite instability, which affects microsatellites found throughout the genome. Microsatellites have several alleles, which are determined by changes in the number of repetitions of a motif unit. Microsatellite instability is of great importance in the oncogenesis of malignant neoplasms. The aim of this work was to study the microsatellite instability of primary cell lines of poorly differentiated glial tumors at different passages in comparison with the patient’s primary tumor material. Tumor cells of primary cultures of anaplastic astrocytoma and glioblastoma at different passages were used as material for the study. Formalin-fixed paraffin wax (FFPE) slides were used as a microsatellite control. Microsatellite analysis was performed on primary cultures of anaplastic astrocytoma and glioblastoma using the following markers: D17S250, D2S123, D5S346, NR21, NR24, NR27, BAT25, BAT26 by PCR. Microsatellite analysis has shown that primary glioblastoma cell lines are genetically more stable than primary anaplastic astrocytoma cell lines.

Tobacco smoking, as a harmful individual habit, aggravates the negative environmental effects on health in people living in the northern regions of Russia, by increasing the incidence of diseases of the cardiovascular and respiratory systems, and oncological diseases. This study was aimed at elucidating the vasomotor reactions on local cooling in young people with nicotine addiction. Materials and methods. Twenty four practically healthy people (13 m, 11 f) aged 18-27 years were enrolled to the study. Of these, 16 subjects with initial stage of nicotine addiction formed the study group, and 8 non-smoking subjects served as a reference group. The degree of nicotine addiction was assessed with the Fagerstrom test and the smoking index. The local cold test (LCT) was used to study vasomotor reactions. The autonomous regulation was estimated by analyzing the time- and frequency-domain characteristics of heart rate variability (HRV). Results. In the group with nicotine addiction, increased cold-induced vasoconstriction was revealed from the dynamics of the hand skin temperature during LCT. Also, this group mwas characterized by decreased vagotonia seen as lower values of time- (SDNN, RMSSD, pNN50 and CV) and frequency- domain (TP, HF and LF) parameters of HRV. The functional test with deep controlled breathing revealed in this group lower reactivity of neurogenic mechanisms of heart rate control. Among subjects with higher number of cigarette consumption, HRV changes which corresponded with adaptation disorders were more notable. Conclusion. Individuals with initial degree of nicotine addiction were characterized by the impaired reactivity of the central and peripheral parts of the circulatory system what means lower health capacity of the organism. Increased vascular reactivity during LCT, as well as the impaired adaptation seen with HRV analysis, could serve as early indicators of the systemic effects of tobacco smoking.

Published: April 2021

Chronic compression injury elevates oxidative stress and inflammation leading to neuropathic pain that is alleviated by rutaecarpine in a dose-dependent manner. To understand the mechanism(s) underlying rutaecarpine effects on this process, changes in the expressions of the proteins and messenger ribonucleic acids for tumor necrosis factor-α, interlukin-6, and interleukin-1β were assessed. Also, the pathology of the sciatic nerve tissue was examined histologically. Furthermore, the expression of the levels of malondialdehyde, superoxide dismutase, and glutathione proteins were evaluated as markers of oxidative stress. Studies aimed at the understanding the mechanisms underlying actions of rutaecarpine suggested it to exert a protective effect on neuropathic pain in a chronic compression injury rat via activating nuclear-factor erythroid 2-related factor 2/Heme oxygenase-1 and inhibiting 6-phosphofructo-2-kinase/fructose-2,6-biphosphatase 3 gene pathways.

Pirmasis COVID-19 infekcijos atvejis buvo patvirtintas Kinijoje, o vėliau išplito visame pasaulyje, įskaitant ir Lietuvą. Skyrus didžiausią dėmesį COVID-19 pandemijai įveikti bei taikant eilę socialinius ryšius ribojančių priemonių, iškilo grėsmė atsirasti psichologinių problemų. Tiriant pandemijos įtaką asmens psichikos būklei, išskiriami pagrindiniai rizikos veiksniai (fizinė atskirtis ir izoliacija, pajamų nestabilumas, amžius ir lėtinės ligos) ir jų sąlygotos psichosocialinės problemos (stresas, depresija, nerimas, somatoforminiai sutrikimai, polinkis į priklausomybes, savižudybę). Lietuvos Respublikos Vyriausybė patvirtino veiksmų planą, skirtą ilgalaikėms neigiamoms psichikos sveikatos pasekmėms, sukeltoms COVID-19 pandemijos, mažinti. Didžioji dalis tyrimų, nagrinėjančių psichikos sveikatos problemas COVID-19 pandemijos metu, buvo atlikti Kinijoje. Jų paskelbtose gairėse išskirti keturi pagrindiniai aspektai: kova su dezinformacija, psichologinės paramos integravimas į kasdienį gyvenimą, visų specialybių gydytojų mokymas suteikti psichologinę pagalbą, tarptautinis bendradarbiavimas. Norint organizuoti tinkamą psichosocialinę pagalbą, svarbu, kad psichikos sveikatos gerinimo planai būtų savalaikiai bei moksliškai pagrįsti.
Gyvensenos veiksnių reikšmė prostatos vėžio progresavimui aktyviai stebimiems pacientams
Authors: Širvinskienė Rasa
Published: April 2021

Prostatos vėžys yra antra dažniausia vyrų onkologinė liga pasaulyje ir pati dažniausia vyrų onkologinė liga Lietuvoje. 2018 m. pasaulyje buvo užregistruota daugiau nei 1,3 mln. prostatos vėžio atvejų [1]. Daugybė atliktų tyrimų parodė gyvensenos ir prostatos vėžio rizikos santykį, bet yra nedaug tyrimų, kurie būtų sutelkę dėmesį į gyvensenos reikšmę prostatos vėžio progresavimui. Prostatos vėžiu sergančių pacientų aktyvi stebėsena suteikia geresnes galimybes vertinti gyvensenos pokyčių reikšmę ligos progresavimui, nes nėra iškraipančių gydymo rezultatų [2].
La verdad sobre el Aleph. Contrapunto humorístico entre Fontanarrosa y Borges
Authors: Palacios Cristian
Published: April 2021

A partir de la consideración del humorismo como un campo discursivo, el artículo se propone estudiar los modos en que la obra de Fontanarrosa retoma algunos de los más recurrentes motivos borgeanos tanto en sus historietas como en sus cuentos, haciéndolos pasar por la matriz discursiva de la risa. Partiendo de un cruce teórico entre semiótica y estudios discursivos analizaremos cómo Fontanarrosa reformula y transforma la obra del escritor con un sentido político muy preciso: el de invertir el gesto de la gauchesca decimonónica, que hacía uso de la “voz” de la culturas subalternas, desde el campo de la cultura letrada. Aquí, partiendo de la apropiación de la obra de Borges, se trata de hacer uso de la cultura letrada desde un tipo de lenguaje tradicionalmente adscripto a la cultura de masas, para acabar, finalmente, disolviendo los límites y las diferencias entre una y otra.
La novela negra entre realidad, historia y ficción. "El caso Bonapelch", de Hugo Burel
Authors: Gatti Riccardi Giuseppe
Published: April 2021

La novela El caso Bonapelch, que Hugo Burel (Montevideo, 1951) publicó a mediados de 2014, representa el caso más significativo de incursión en el género policial del autor uruguayo. Sobre la base de una anécdota temática que conecta la ficción con la historia real del país durante los años treinta, Burel crea un personaje, el inspector Santini, que –en sus tentativas frustradas de resolver el entonces célebre caso policial– bascula entre la dimensión de la ficción y los sucesos históricos. En el relato se evidencia, por una parte, la intuición de utilizar el género policial como herramienta discursiva para la representación de elementos socio-históricos idiosincráticos de la cultura local; por otra parte, el texto narrativo reelabora los modelos canónicos del género policial.
