Denaturalization as a special ground for termination of legal ties with the state
Authors: Proniakina Svetlana
Published: December 2021

The legal grounds for acquisition and revocation of citizenship by persons born and residing on the territory of different states may differ significantly due to historical, political, economic, and other reasons. This article provides a comprehensive analysis of the grounds for revocation of citizenship – denaturalization. The author establishes the factors and circumstances that contribute to termination of the political0legal ties of an individual with the state upon the initiative of the state. The article explores the international legal acts, as well as conducts a comparative analysis of the legislation of different countries on the issues of denaturalization. The author reviews the conditions and restrictions for implementation of the procedure for revocation of citizenship by the state, as well as correlation of such grounds for termination of citizenship as revocation of citizenship and reversal of decision on naturalization. The scientific novelty lies in the conclusion that revocation of citizenship is not prohibited by the international legal acts if there are legal grounds established by the domestic legislation of the country. Such grounds may include unlawful actions of a citizen against public security and national interests, as well as other actions that undermine the fundamentals of the constitutional system. The author offers the open legislative consolidation of the legal institution of denaturalization for the possibility of revocation of citizenship of an individual upon the initiative of the state.
Regulatory sandboxes: comparative-legal study on the institution of experimental legal regimes in the Russian Federation and regulatory laboratories in Georgia
Authors: Makarov Vladislav Olegovich
Published: December 2021

This article carries out a comparative-legal study of the institution of regulatory sandboxes in the Russian Federation and Georgia. Based on the information acquired upon the request of the National Bank of Georgia, the author examines the normative regulation of regulatory laboratories of Georgia – Decree of the President of the National Bank of Georgia No. 110/04 of May 25, 2020 “On the Approval of Establishment of Regulatory Laboratories by the National Bank of Georgia and their Use", as well as its comparison with the federal law and normative acts that regulate experimental legal regimes in Russia. The application of comparative-legal methods allows determining the similarities and differences in legal regulation and practice of implementation of such institutions in the Russian Federation and Georgia. Description is given to the terminological differences in legislation on legal experiments of the two countries, as well as the differences in the model of legal regulation of the institution of experimental legal regimes: comprehensive regulation by means of the federal law and normative acts in the Russian Federation, and overall regulation solely by the Decree of the President of the National Bank of Georgia. Georgia allows experimental regulation applicable exclusively to financial technologies, while the Russian Federation allows for a broader scope of implementation. This substantiates the differences in the requirements of initiators and authorities that regulate such legal experiments. The conclusion is made on the more successful practice of implementation of legal experiments in the sphere of financial technologies in Georgia, despite the absence of special law or large array of developing legislation.
Deliberate distortions of the concepts of “West” and “East” in media discourse
Authors: Yuan Lin
Published: December 2021

This article dedicated to identification distortions in the traditional interpretations of the concepts of “West” and “East” in modern Russian media discourse. The goal lies in outlining separate aspects of distortion of these concepts and determination of causes for the emergence of such distortions in mass media discourse. The object of this research is the modern Russian media discourse that takes place in the online space. The subject is the distortions of media discourse. The article employs the analysis of scientific literature, linguoculturological text analysis, comparison and systematization of research results, continuous sampling, and keyword search. The scientific novelty consists in the fact that that this article is first to examine distortions of the concepts of “West” and “East”. It is revealed that the content of the concept of “West”, namely such aspects as modernity, progressiveness, development of new technologies, wealth, etc., are exposed to distortions the most; while the concept of “East” and its components, such as tradition, ancient civilization, despotism of state power, vestige of the past, impairment of rights of the women, and specific mode of living remain virtually unchanged. The conclusion is made that distortions of the concept of “West” and consistency of the concept of “East” in media discourse may be associated with the orientation of modern Russia towards Eastern civilization, as well deliberate opposition of Russia and the West presented in media discourse.
Macro-semantic rhythmic structures in popular author songs
Authors: Zipunov Andrey , Valganov Sergei Vladimirovich
Published: December 2021

Certain author song of the 1950s – 1980s are characterized with such structural peculiarity as semantic rhythms. This pattern manifests itself in two forms: dialectical juxtaposition of the particular and the general (PG-rhythm); as well as the conflict of non-entropic and entropic processes, order and chaos (OC-rhythm). For broader understanding of this phenomenon, it is necessary to determine its place within the framework of the author song as a large-scale cultural phenomenon. The author mass processing of popular compositions using the method of almost full enumeration. The research material includes all 5 thematic national collections that feature 487 songs. The analysis of the lyrics reveals the total number of works with the initial semantic rhythmics: 43% with the PG-structure and 23% with the OC-structure. The application of various strategies of analysis indicates that the sampling of no less than 70-80 compositions should be used for achieving accurate results in partial studies (for example, by authors) . In the course of research, the author determines new versions of manifestation of the semantic structures: PG-structure of fable-type, as well as variability of Brodsky's saw in songs with entropic rhythmics. There are also songs with intersection of both types of semantic rhythms. Correlation is established between the social processes of cultural environment associated with the author song and the dynamics of semantic rhythms in popular compositions. In the early 1970s, a bifurcation point is noticed in the moods of the corresponding social community.
A leitura acadêmica como prática discursiva para o ensino de metodologia científica
Authors: Mendes Maria das Dores Nogueira , Matos José Wesley Vieira
Published: December 2021

Partindo da observação do discurso sobre a leitura acadêmica e percebendo algumas lacunas relacionadas à naturalização e elitização desse processo de letramento, ao enfoque grafocêntrico, como também às práticas de ensino de caráter imediatista voltadas à produção, propomos, neste estudo, refletir sobre a leitura como prática discursiva e as implicações pedagógicas disso para o ensino de metodologia científica no contexto universitário. Apoiados nas discussões desenvolvidas por Orlandi (2007; 2008), Possenti (1992; 2009a) e, principalmente, Maingueneau (1997; 2004; 2008; 2015), apresentamos os conceitos que podem fundamentar uma perspectiva discursiva da leitura, tais como campo discursivo, posicionamento, investimentos discursivos, formas de textualidade e competência (inter)discursiva. Tal aporte não aparece desconexo de uma sistematicidade didática, por isso, também enfatizamos o papel basilar da leitura para as práticas de pesquisa exploratória e, de forma geral, para as demais práticas nucleares do campo. No centro das discussões, o tipo de comunidade fechada, as características gerais das práticas genéricas, os papéis dos parceiros legítimos em relação com a especificidade das cenas genéricas científicas e a coincidência dos sujeitos produtores e consumidores reforçam que, na ciência, os atos de leitura são aliados aos de produção. Dessa forma, esperamos contribuir com as discussões sobre um ensino de metodologia científica mais reflexivo que não subentenda a leitura como dada, nem a relegue a um lugar menor, mas busque compreendê-la, na medida em que enfocamos as competências genérica e (inter)discursiva, enquanto prática clivada e constitutiva do trabalho investigativo
Afrontas queer/cu-ir: linguagem não-binária na escrita acadêmica (implicações políticas e possibilidades)
Authors: Santos Filho Ismar Inácio dos
Published: December 2021

A discussão sobre linguagem (não) sexista e a respeito de ativismo linguístico não é nova. Se recuperarmos seu histórico, podemos ir ao século 18, quando Olympe de Gouges propôs a Declaração dos Direitos das Mulheres, com o argumento de que elas não se sentiam incluídas com a Declaração dos Direitos do Homem e do Cidadão, e também em contraposição à tradição gramatical francesa, conforme Borba (2020) e Lopes (2021). No Brasil, essa discussão é “recente”, inicialmente no espaço da academia, no âmbito do feminismo. Todavia, nesses últimos anos, no ativismo transfeminista, a reivindicação por uma linguagem não-binária ganhou popularidade e chegou ao debate público, mobilizando inclusive o poder legislativo brasileiro, que vêm propondo decretos que visam proibir o uso do “gênero neutro” na esfera escolar e na administração pública. É nesse cenário de disputas linguístico-ideológicas que nos propomos a refletir acerca de possibilidades e implicações políticas do uso dessa linguagem na escrita acadêmica, numa maneira de afronta queer/cu-ir às normatividades/normalidades de língua e de corpos em nossa cultura. O estudo dialoga com Carvalho (2021), Bagno (2019), Borba (2020), Fabiano (2004; 2020), Lagares (2018; 2020), Moita Lopes (2013), Melo (2021) e Santos Filho (2015; 2020), dentre outras reflexões, e argumenta que usar a linguagem não-binária na escrita acadêmica é atuar para provocar urgentes desestabilizações de sentido, atuando na microfísica das tramas de forças do dizer científico, de modo a reconhecer todes
The Role of Turkish Drones in Azerbaijan’s Increasing Military Effectiveness: An Assessment of the Second Nagorno-Karabakh War
Authors: Kınık Hülya , Çelik Sinem
Published: December 2021

This study focuses on Turkey as a rising drone power in the international arena in recent years. In this context, the article will scrutinize the case of the Second Nagorno-Karabakh War, which broke out on September 27, 2020. The Nagorno-Karabakh conflict, one of the frozen problems in the Caucasus region, was ended in favor of Azerbaijan less than two months later. Turkey took on a game-changing role in the region by supplying its ally Azerbaijan with unmanned aerial vehicles (UAVs) for use in the conflict, and significantly contributed to Azerbaijan’s victory. Turkey’s political, diplomatic, and military contributions to Azerbaijan will likely be discussed on the global agenda for years to come; this study will contribute to the literature on the role and impact of Turkey’s military support, especially its drones, on Azerbaijan’s Nagorno-Karabakh victory.
Russia’s Policy during the 44-day of the Karabakh War
Authors: JAFAROV Nazim , ASLANLI Araz
Published: December 2021

The 44-day Karabakh War seriously affected the international balances in the Caucasus in terms of security, politics, and economic dimensions. The attitude of international actors during the war was important to define the fate and consequences of the war. Among these international actors, Russia’s attitude was of special importance. The policy followed by Russia during and after the 44-day Karabakh War had four main and parallel pillars: The first pillar of Russia's policy was maintaining the status of its traditional ally Armenia. The second pillar was maintaining its mediator role for the resolution of the conflict. The third pillar of the policy pursued by the Kremlin was not harming the strategic partnership relationship with Azerbaijan, which had been specially developed during Vladimir Putin’s tenure. The fourth pillar of the policies pursued by Russia was not disrupting the multidimensional profound relationships with Turkey, which had advanced in recent years. The first two dimensions of this policy followed by the Putin Administration during the 2nd Karabakh War represent Russia’s conventional Caucasus policy and the last two dimensions embody a policy change.
Turkey’s Strategic Conduct under the Changing International System
Authors: Yeşiltaş Murat , Pirinççi Ferhat
Published: December 2021

This article analyses how Turkey should orient its grand strategy under the changing international order. It claims that the international order has undergone a significant transformation that is pushing Turkey to relocate its international position. First, the article analyses the characteristic features of the changing dynamics of the international system; it then sheds light on the new aspects of Turkey’s changing strategic landscape. By taking into consideration the transformation in Turkish foreign and security policy since the Arab Uprising, the article argues that Turkey needs a basis for determining what is important and what is not, what the primary threats to the nation’s interests are, and how best to serve those interests in a way that is attentive to the costs and risks it is willing to bear. Our aim in this article is to describe how Turkey can deal with the new reality of the international system and pursue and protect its important interests by developing a comprehensive grand strategy.

СТРУКТУРНЫЕ ФАКТОРЫ УПРОЧНЕНИЯ УГЛЕРОДИСТОЙ ИНСТРУМЕНТАЛЬНОЙ СТАЛИ У8А ПРИ ЦИКЛИЧЕСКОМ ТЕПЛОВОМ ВОЗДЕЙСТВИИ

Published: December 2021

В работе представлены результаты изучения структурных факторов упрочнения углеродистой инструментальной стали У8А при циклическом тепловом воздействии. Изучено влияние высокотемпературной термоциклической обработки с неполными фазовыми превращениями на её структуру и физико-механические свойства. Проведены металлографические исследования с применением методов цветного травления, сравнительный фазовый анализ образцов из стали У8А после традиционной закалки и ТЦО с последующим двухчасовым отпуском при температуре 200 °С. Сравнивали строение и состав образцов, имеющих одинаковые значения твердости – 60НRCэ, но различные значения ударной вязкости КС. Анализ микроструктуры, определение морфологии составляющих, осуществляли при помощи программного комплекса «Thixomet PRO» и металлографического микроскопа «Carl Zeiss Axio Observer Z1m». Установлено, что в результате ТЦО происходят следующие основные изменения: изменяется структура стали (происходит перераспределение структурных составляющих, значительно снижается содержание остаточного аустенита (более чем в 3 раза), снижается общее количество карбидов (в 1,5 раза), происходит их измельчение, сфероидизация и перераспределение в объёме); снижается уровень внутренних напряжений; основным местом зарождения трещин являются большие частицы карбидов, основным путем распространения трещин – межфазные границы “α-фаза-карбид” и внутрифазные границы в α-фазе. Измельчение, сфероидизация и перераспределение карбидов затрудняет зарождение микротрещин и их распространение. В результате всех этих структурных изменений, происходящих под воздействием ТЦО, значительно повышается ударная вязкость и сохраняется высокая твердость стали. Окончательная ТЦО стали У8А по оптимальным режимам приводит к повышению ее ударной вязкости до 7-8 раз при сохранении высокой твердости. При небольшом увеличении длительности процесса ТЦО технология термообработки по сравнению с традиционной (закалкой и отпуском) обеспечивает повышение эксплуатационной стойкости инструмента в 1,5-2 раза и более.

В настоящей работе впервые охарактеризован касситерит фумарольного генезиса. Он найден в отложениях активной фумаролы Арсенатной (второй шлаковый конус северного прорыва Большого трещинного Толбачинского извержения 197576 гг., Толбачинский дол, вулканический массив Толбачик, Камчатка), где тесно ассоциирует с солевыми минералами сильвином, галитом и щелочными сульфатами группы афтиталита, а также с безводородными арсенатами Ca, Mg, Na, Fe и Cu. Касситерит здесь представлен пушистыми мягкими радиально-лучистыми агрегатами тонкоигольчатых до волосовидных кристаллов в полостях, что является следствием быстрой кристаллизации из газовой фазы. Также он образует сагенитовую решетку на гематите, что зафиксировано для касситерита впервые. Эксгаляционный касситерит характеризуется необычно высокими содержаниями примесных компонентов: титана (до 21.1 мас. TiO2), сурьмы (до 9.3 мас. Sb2O5), железа (до 5.8 мас. Fe2O3) и меди (до 0.5 мас. CuO), изоморфно замещающих олово. Наиболее часто в нем реализуется изовалентная схема изоморфизма Sn4 Ti4. Зафиксированы также совместное вхождение Sb5 и трехвалентных компонентов по трипугиитовой схеме 2Sn4 Sb5 (Fe,Al) 3 и вхождение двухвалентных катионов, в первую очередь меди, по схеме 3Sn4 2Sb5 Cu2 предполагается, кроме того, гетеровалентная схема с участием кислородных вакансий: 2Sn4 O2 2(Fe,Al) 3 vac 0. В фумаролах Толбачика распространен оловосодержащий (до 7.1 мас. SnO2) гематит, в том числе содержащий эмульсионную вкрапленность касситерита или решетчатые образования, сложенные его ламелями. Это позволяет считать, что при высоких температурах (450750 оC) гематит и касситерит в данной системе образуют твердый раствор (Fe,Sn)2xO3, где, по нашим эмпирическим данным, x 0.025. При снижении температуры он может распадаться на гематит без олова (или с его низким содержанием) и касситерит.

STABILITY OF THE REST POINTS FRACTIONAL OSCILLATOR FITZHUGH-NAGUMO
Authors: Липко О.Д.
Published: December 2021

В работе с помощью качественного анализа были исследованы на устойчивость точки покоя дробного осциллятора ФитцХью-Нагумо в соизмеримом и несоизмеримом случаях. Для соответвующей точки покоя, с помощью численного метода теории конечно-разностных схем, была построена фазовая траектория. Показано, что точки покоя могут быть как асимптотически устойчивыми, что соответствуют устойчивым фокусам, так и являться асимптотически неустойчивыми (неустойчивыми фокусами), причем для них фазовые таректории, как правило, выходят на предельный цикл.

In this paper, using the qualitative analysis, we studied the stability of the point of rest of the fractional oscillator FitzHugh-Nagumo in commensurate and incommensurable cases. For the corresponding point of rest, using the numerical method of the theory of finite difference schemes, phase trajectories were constructed. It is shown that quiescent points can be both asymptotically stable, which correspond to stable focus, and are asymptotically unstable (unstable focus), and for them the phase trajectories usually go to the limit cycle.

Metal-organic framework-808 has been functionalized with 11 amino acids (AA) to produce a series of MOF-808-AA structures. The adsorption of CO2 under flue gas conditions revealed that glycine- and DL-lysine-functionalized MOF-808 (MOF-808-Gly and -DL-Lys) have the highest uptake capacities. Enhanced CO2 capture performance in the presence of water was observed and studied using single-component sorption isotherms, CO2/H2O binary isotherm, and dynamic breakthrough measurements. The key to the favorable performance was uncovered by deciphering the mechanism of CO2 capture in the pores and attributed to the formation of bicarbonate as evidenced by 13C and 15N solid-state nuclear magnetic resonance spectroscopy studies. Based on these results, we examined the performance of MOF-808-Gly in simulated coal flue gas conditions and found that it is possible to capture and release CO2 by vacuum swing adsorption. MOF-808-Gly was cycled at least 80 times with full retention of performance. This study significantly advances our understanding of CO2 chemistry in MOFs by revealing how strongly bound amine moieties to the MOF backbone create the chemistry and environment within the pores, leading to the binding and release of CO2 under mild conditions without application of heat.
Interdependent Dynamic Nitroaldol and Boronic Ester Reactions for Complex Dynamers of Different Topologies
Authors: Karalius Antanas , Qi Yunchuan , Ayinla Mubarak , Szabo Zoltan , Ramstrom Olof
Published: December 2021

Complex dynamic systems displaying interdependency between nitroaldol and boronic ester reactions have been demonstrated. Nitroalkane-1,3-diols, generated by the nitroaldol reaction, were susceptible to ester formation with different boronic acids in aprotic solvents, whereas hydrolysis of the esters occurred in the presence of water. The boronic ester formation led to significant stabilization of the nitroaldol adducts under basic conditions. The use of bifunctional building blocks was furthermore established, allowing for main chain nitroaldol-boronate dynamers as well as complex network dynamers with distinct topologies. The shape and rigidity of the resulting dynamers showed an apparent dependency on the configuration of the boronic acids.
Measuring anion binding at biomembrane interfaces

Published: December 2021

Understanding non-covalent molecular recognition events at biomembrane interfaces is important in biological, medicinal, and materials chemistry research.1 Despite the crucial regulatory roles of anion binding/transport processes at biomembranes, no information is available regarding how strongly anions can bind to naturally occurring or synthetic receptors in lipid bilayer environments compared to their well-established behaviour in solutions.2 To bridge this knowledge gap, we synthesised a flat macrocycle that possesses a record aqueous SO42– affinity among neutral receptors and exploited its unique fluorescence response at interfaces. We show that the determinants of anion binding are extraordinarily different in organic solvents and in lipid bilayers. The high charge density of dihydrogen phosphate and chloride ions prevails in DMSO, however in lipids they fail to bind the macrocycle. Perchlorate and iodide hardly bind in DMSO but show significant affinities for the macrocycle in lipids. Our results demonstrate a surprisingly great advantage of large, charge-diffuse anions to bind to a lipid-embedded synthetic receptor mainly attributed to their higher polarisabilities and deeper penetration into the bilayer, beyond the common knowledge of dehydration energy-governed selectivity. The elucidation of these principles enhances our understanding of biological anion recognition functions in membranes and guides the design of ionophores and molecular machines operating at biomembrane interfaces.
A platform for stop flow gradient generation to investigate chemotaxis
Authors: Xiao Zuyao , Nsamela Audrey , Garlan Benjamin , Simmchen Juliane
Published: December 2021

The ability of artificial microswimmers to respond to external stimuli and the mechanistical details of their origins belong to the most disputed challenges in interdisciplinary science. Therein, the creation of chemical gradients is technically challenging, because they quickly level out due to diffusion. Inspired by pivotal stopped flow experiments in chemical kinetics, we show that microfluidics gradient generation combined with a pressure feedback loop for precisely controlling the stop of the flows, can enable us to study mechanistical details of chemotaxis of artificial Janus micromotors, based on a catalytic reaction. We find that these copper Janus particles display a chemotactic motion along the concentration gradient in both, positive and negative direction and we demonstrate the mechanical reaction of the particles to small forces deviations, explaining this behaviour.
Analysis of Preferred Mechanisms of CO Oxidation with Atomically Dispersed Pt1/TiO2 Using the Energetic Span Model
Authors: Bac Selin , Mallikarjun Sharada Shaama
Published: December 2021

This work examines the mechanisms of low-temperature CO oxidation with atomically dispersed Pt on rutile TiO2 (110) using density functional theory and the energetic span model (ESM). Of the 13 distinct pathways spanning Eley-Rideal (ER), termolecular ER (TER), Langmuir-Hinshelwood(LH), Mars-Van Krevelen (MvK) mechanisms as well as their combinations, TER with CO-assisted CO2 desorption yields the highest turnover frequency (TOF). However, this pathway is ruled out because Pt is dynamically unstable in an intermediate state in the TER cycle, determined in a prior ab initio molecular dynamics study by our group. We instead find that a previously neglected pathway – the ER mechanism – is the most plausible CO oxidation route based on agreement with experimental TOFs and turnover-determining states. The preferred mechanism is sensitive to temperature, with LH becoming more favorable than ER and TER above 750 K. By comparing TOFs for Pt1/TiO2 with prior mechanistic studies of various oxide-supported atomically dispersed catalysts in the literature, we also attempt to identify the most viable metal and support materials for CO oxidation.

В работе впервые было исследовано влияние наночастиц серебра на люминесценцию иттрий-алюминиевого граната, легированного церием. С помощью метода химического восстановления был синтезирован золь с размером наночастиц серебра ≈100 нм. Керамический порошок люминофора иттрий-алюминиевого граната, легированного церием, был получен методом двухстадийного осаждения в уротропин. Золь наночастиц серебра в концентрациях от 0,125 до 0,1 мл вводили в порошок-прекурсор перед прокаливанием. Было показано, что при данном способе введения наночастиц серебра интенсивность фотолюминесценции возрастала по сравнению с эталоном. Оптимальной концентрацией в рамках исследования являлась концентрация 0,25 мл. При данной концентрации увеличение интенсивности фотолюминесценции на длине волны 540 нм составило порядка 10%. Проведенные исследования показали, что наночастицы серебра могут с успехом применяться для увеличения яркости люминофора иттрий-алюминиевого граната, легированного церием, без искажения и ухудшения спектральных характеристик.

This work was the first to study the effect of silver nanoparticles on the luminescence of cerium doped yttrium-aluminum garnet. A sol with the size of silver nanoparticles of ≈100 nm was synthesized using the method of chemical reduction. Phosphor ceramic powder of the yttrium-aluminum garnet doped with cerium was obtained by the two-stage precipitation method. The silver nanoparticles sol was introduced into the precursor powder before calcination in concentrations from 0,125 to 0,1 ml. It was shown that the photoluminescence intensity increased in comparison with the reference when we used this method of introducing silver nanoparticles. The optimal concentration within the study was 0,25 ml. At this concentration, the increase in the photoluminescence intensity at a wavelength of 540 nm was about 10 %. Studies have shown that silver nanoparticles can be successfully used to increase the brightness of the phosphor of the yttrium-aluminum garnet doped with cerium without distortion and deterioration of spectral characteristics.

Para refletir, de que forma a história de mulheres educadoras desde os movimentos sociais latino-americanos Ã  figura feminina nas contradições sociais do século XXI, podem colaborar para uma construção social baseada na igualdade de direitos, pensamos: As transformações da sociedade tanto no que diz respeito ao fator econômico, ou acerca do consumo presente no sistema do capital, as questões de gênero, a influência da mídia na sociedade, e principalmente a permanência da mulher como protagonista neste século, vem fortalecendo os movimentos sociais já existentes cujo os direitos das mulheres são principal foco bem como a inspiração cada vez mais forte de novos movimentos, como exemplo desta década temos o movimento da teologia feminista, que possibilita a reflexão do papel da mulher na religião sem a submissão histórica dos antepassados. Diante dos debates, muitas perguntas surgem, pois há contradições destas relações que precisam ser pensadas

Junto aos esfarrapados do mundo
Authors: Almeida Ana Lia
Published: December 2021

Este artigo resulta da sistematização de parte das análises empreendidas na tese de doutorado “Um estalo nas faculdades de direito: perspectivas ideológicas da assessoria jurídica universitária popular” (2015). Em “Junto aos esfarrapados do mundo: a educação popular da Assessoria Jurídica Popular”, busco problematizar as possibilidades, as contradições e as limitações das atividades de educação popular, inspiradas em Paulo Freire, desenvolvidas pelos grupos de assessoria jurídica universitária popular (AJUP). Delimito a concepção de “educação popular” destes grupos a partir de relatos deles próprios sobre suas práticas, identificando alguns dilemas desta atuação. No plano teórico, as análises encontram-se no campo da tradição marxista, em dialogo com as ideias de Paulo Freire e com importantes referências orgânicas da assessoria jurídica popular.

Published: December 2021

Background. There is a progressive increase of respiratory allergic diseases nowadays in the world, made it necessary to study the participation of the components of the immune system in these processes. From the point of view of modern aspects about the organs of the immune system, interesting are the patterns of morphogenesis and function of bronchus associated lymphoid tissue, occupied a special place in the immunological protection of the body due to the large area of contact with various antigens. Morphogenesis and reactive changes in the local immunity in respiratory system in conditions of allergic inflammation remain urgent issue of modern morphology. Objective. To study the changes in diffuse lymphoid tissue of bronchi and lungs of guinea pigs sensitized with ovalbumin. Methods. We have studied the lung of 48 guinea pigs, using histological, immunohistochemical, morphometric, statistical methods, under conditions of experimental ovalbumin-induced allergic inflammation, assessed the average number of lymphocytes, macrophages and plasma cells in the diffuse lymphoid tissue. Results. The average number of lymphocytes in diffuse lymphoid tissue of bronchi and lungs increased from the 23rd day of observation and remained at a high level until the end of the experiment, the maximum was during the early period of the development of allergic inflammation, the increasing coefficient was 4.7. The average number of plasma cells also acquired maximum elevation in the early period of allergic process, the increasing coefficient was 2.0. The most significant average number of macrophages was on the 23rd day of observation with same increasing coefficient. Among all types of immunocompetent cells of diffuse lymphoid tissue in bronchi and lungs, T-lymphocytes prevailed during the experiment elevated almost by 5 times. Conclusions. In the early period of development of experimental ovalbumin-induced allergic inflammation, the specific resistance of the respiratory system manifests itself in the form of activation of local links of cellular and humoral adaptive immunity, as evidenced by the dynamics of changes in the average number of lymphocytes (the maximum increasing coefficient 4.7 in the 1st experimental group), macrophages and plasma cells (maximum increasing coefficient 2.0 in the 1st experimental group) of diffuse lymphoid tissue of bronchi and lungs of guinea pigs.

Salah satu masalah kesehatan masyarakat yang masih banyak terjadi di Indonesia khususnya pada ibu hamil adalah masalah anemia. Anemia dalam kehamilan berdampak membahayakan bagi ibu dan janin. Mengubah tingkah laku membutuhkan metode yang lebih dramatis daripada sekedar mengajari/memberi tahu. Demonstrasi sangat berguna karena orang sering merasa terpengaruhi oleh apa yang mereka lihat, apa yang mereka lakukan dan apa yang orang lain lakukan. Tujuan dari penelitian ini adalah Menganalisis Pengaruh Model Behaviour Centered Design (BCD) Melalui Permainan Emo-Demo ATIKA SABU (Ati, Telur, Ikan, Sayur dan Buah) Terhadap Pengetahuan, Sikap dan Tingkah laku Pencegahan Anemia Pada Ibu Hamil. Metode Penelitian ini menggunakan metode quasi experimental research dengan 1 kelompok kontrol dan 1 kelompok perlakuan. Jumlah sampel 60 ibu hamil yang yang masing-masing setiap kelompok terdiri dari 30 orang, berdasarkan criteria ekslusi dan inklusi. Pengolahan data menggunakan uji mann-whitney. Hasil penelitian menunjukkan bahwa perbedaan peningkatan skor rata-rata pengetahuan, sikap dan tingkah laku ibu hamil setelah diberikan edukasi pencegahan anemia pada kelompok emo demo dengan kelompok kontrol adalah pengetahuan sikap dan tingkah laku . Hasil uji statistik pengetahuan dengan nilai p-value = 0,0001 sikap dengan nilai p-value = 0,0001 dan tingkah laku dengan p value = 0,0001. Kesimpulan dalam penelitian ini ada perbedaan yang signifikan antara kelompok emo demo dengan kelompok kontrol setelah diberi edukasi. Diharapkan agar diadakan pelatihan edukasi kesehatan menggunakan media Emo Demo untuk ibu hamil dalam meningkatkan pengetahuan, sikap dan tingkah laku tentang anemia dan salah satu upaya untuk menurunkan kejadian anemia pada ibu hamil.Kata Kunci : Emo Demo, Anemia, Pengetahuan, Sikap, Tingkah laku

Lupus cystitis is an uncommon manifestation of systemic lupus erythematosus (SLE). We describe the case of a 23-year-old woman with lupus that complained of abdominal pain, vomiting, and diarrhea for one week. Two years back, she was brought with an affirmative history that satisfied the clinical criteria of SLE which was renal biopsy-proven (class V membranous lupus nephritis). On radiologic workup, she was found to have bilateral hydronephrosis and a thick-walled bladder with diverticula. Immunosuppressive therapy was commenced however augmentation cystoplasty had to be opted for as the symptoms did not subside with medical therapy alone.

Digital Transformation: Smart Strategy in Administrative Reform in Vietnam
Authors: Thanh Nguyen Hai
Published: December 2021

Objectives: Digital transformation is becoming such a big trend that countries worldwide cannot resist because it brings prosperity and development to social progress. Therefore, countries, especially emerging countries, need to quickly bring the latest technology advances into socio-economic development. Therefore, the purpose of the article is to point out the theoretical issues of digital transformation, the advantages and challenges, and their impact on Vietnam's provincial administrative reform and forecast the trend of impacts of the digital transformation to administrative reform at the provincial level. Methods/Analysis: Qualitative and quantitative research methods have been used together, in which quantitative methods used available literature sources. The qualitative method has been developed based on designing two questionnaires on digital transformation and administrative reform, thereby exploring the current results of digital transformation and administrative reform in a cross-section. Findings: Research has shown that the reality of digital transformation and administrative reform in provincial administrative agencies in Vietnam is still limited. Although administrative reform is superior to digital transformation, they are closely positive related. Novelty /Improvement: Research shows that administrative reform at the provincial level in Vietnam will become more competent and more efficient when administrative agencies promote the application of digital transformation; both digital transformation and administration reform need to be concerned at the same time. Moreover, a more focus on developing digital capacity and skills for civil servants is necessary for digital transformation and administrative reform to achieve high efficiency. Doi: 10.28991/HIJ-2021-02-04-06 Full Text: PDF
ПОСТАННЯ ПСИХОСОФІЙНОГО ДИСКУРСУ ТОЛЕРАНТНОСТІ
Authors: Фурман Анатолій , Шаюк Ольга
Published: December 2021

Мета. У дослідженні вперше окреслено проблемне поле започаткування психософійного дискурсу толерантності, який науково проєктується розгорнути за вчинковим принципом В. А. Роменця, а також за методологічними підходами, нормативами і засобами вітакультурної методології наукової школи А. В. Фурмана.

Методи. Для реалізації мети наукового пошуку були використані методи: психологічного аналізу, проблемно-комунікативного синтезу, індуктивного переходу від конкретного до загального, логіко-змістової дедукції як сходження від загального до одиничного і конкретного, канонічного вчинення у його психософійному витлумаченні.

Результати. В контексті актуальності створення новітньої моделі/концепції толерантності системно розглянуто найбільш значущі точки її ґенези в найважливіших вимірах філософського та наукового осмислення, тенденції розуміння та інтерпретації цього ковітального феномену людського повсякдення, його формовияви суспільного уреальнення і суб’єктного життєзреалізування. Воднораз толерантність розкрито і як важливий концепт сучасного теоретичного мислення і професійного методологування, а також як інтегральну особистісну рису-якість. Однак найважливіша авторська ідея, що сформульована як надзавдання дослідження, полягає в тому, щоб обґрунтувати вчинок толерантності як вузловий осередок життєдіяльності і в першому предметному наближенні визначити його психософійні контури за допомогою системного набору методів: критичного аналізу, рефлексивного синтезу, логічної та емпіричної індукції, смислової дедукції з використанням інтелектуальних засобів миследіяльності і професійного методологічного моделювання. Внаслідок отримано теоретичне обґрунтування моделі вчинку толерантності як взаємодоповнення чотирьох компонентів – ситуаційного, мотиваційного, діяльного і післядіяльного. Таке структурне узмістовлення канонічно організованого вчинення уможливило висвітлення векторів психософії толерантності, аргументування продуктивності розробки психософійного напрямку вивчення толерантності як світоглядної універсалії, котра співвідносить ментальні і мовленнєві, емоційні та інтелектуальні, раціональні та ірраціональні, екзистенційні та моральні складові історичного досвіду людства, збагачує масову свідомість уявленнями про прийнятні форми, методи і засоби соціальних учинків, ситуаційної взаємодії та порозуміння, а відтак програмує життя всіх і кожного згідно із законами гуманності, солідарності, співдружності.

Висновки. Проведене дослідження доводить, що евристичний напрям конструктивної розробки розлогої проблематики людської толерантності є не так її детальним психологічним вивченням, як психософійним осмисленням, ціннісним наповненням і вчинково-канонічним зреалізуванням великих спільнот, малих груп і кожної особистості зокрема. Саме це дає змогу світоглядно програмувати життєвий шлях зрілої особи, яка стала на шлях розсудливого вчинення.
