Vertebrate remains from Upper Silurian – Lower Devonian beds of Hall Land, North Greenland
Authors: Blom Henning
Published: May 2020

Vertebrate microscopic remains of twenty-six taxa of thelodonts, heterostracans, osteostracans, anaspids, acanthodians and chondrichthyans are described from limestone beds in two localities of Late Silurian - Early Devonian age of the Chester Bjerg Formation, Hall Land, North Greenland. The limestone beds form a minor part of a monotonous calcareous sandstone-siltstone-mudstone sequence at the top of the Franklinian Basin succession.Stratigraphical recognition using several thelodont and acanthodian taxa, supported by regional geological and structural trends, suggests a Silurian-Devonian boundary interval between beds of the Halls Grav and Monument localities. This possible resolution of the previous problematic correlation between the two distant sections of monotonous nature demonstrates the potential biostratigraphic utility of thelodonts in Silurian -Devonian marine successions.The Chester Bjerg Formation thelodont assemblage is unique with several new endemic taxa, but Loganellia cf. L. tuvaensis is very similar to the type material of the Tuva region south of Siberia, Russia and indicates a Late Silurian age for the beds of the Halls Grav locality. Canonia cf. C. grossi suggests an Early Devonian age for the Monument locality, since Canonia is so far only found in Lower Devonian marine strata of Arctic Canada and Russia. Fragments of cosmopolitan acanthodian genera such as Poracanthodes, Gomphonchus and Nostolepis are found together with heterostracans, osteostracans, anaspids and chondrichthyans at both localities but do not give a more exact age determination than Late Silurian - Early Devonian. New thelodont taxa are Loganellia almgreeni sp. nov., Paralogania foliala sp. nov., Praetrilogania grabion gen. et sp. nov. and Thulolepis striaspina gen. et sp. nov. Nostolepis halli sp. nov. is a new acanthodian species.

Conducted research and development of appropriate software are of practical importance in the construction/modernization of communication networks.
The dependence of the majority voting decision-making probabilities on a multi-expert binary system experts number
Authors: Avedyan E. D. , Linh Le Thi Trang
Published: May 2020

The article presents the analytical results of the decision-making by the majority voting algorithm (MVA). Particular attention is paid to the case of an even number of experts. The conditional probabilities of the MVA for two hypotheses are given for an even number of experts and their properties are investigated depending on the conditional probability of decision-making by independent experts of equal qualifications and on their number. An approach to calculating the probabilities of the correct solution of the MVA with unequal values of the conditional probabilities of accepting hypotheses of each statistically mutually independent expert is proposed. The findings are illustrated by numerical and graphical calculations.
Alternative signature generation procedures in the digital signature schemes based on the hidden discrete logarithm problem
Authors: Moldovyan D.N. , Moldovyan A.A. , Guryanov D.Yu.
Published: May 2020

Public-key cryptographic algorithms and protocols based on computational difficulty of the factorization problem and on the discrete logarithm problem are widely used in information-telecommunication systems. Currently the problem of construction of the post-quantum algorithms and protocols, i.e. cryptoschemes that are secure to potential attacks using quantum computers, represents a challenge in the area of applied and theoretic cryptography. In the literature the postquantum signature schemes based on the hidden discrete logarithm problem that is formulated in the finite non-commutativeassociative algebras were proposed. A disadvantage of such signature schemes is comparatively large size of the private key. The goal of the study is to develop an alternative signature generation procedures that will allow to reduce significantly the size of the private key. To achieve the goal, it is using the elements of the public key to compute the fixation vector at the first step of the signature formation procedure. As a result, there are designed alternative signature generation procedures in two known signature schemes based on the computational difficulty of the hidden discrete logarithm problem. Application of the proposed procedures gives possibility to reduce the size of the private key. The practical significance of the study is reduction the size of the protected memory in the electronic devices used for computation of the digital signatures.

Cyprian Norwid’s thoughts on independence
Authors: Toruń Włodzimierz
Published: May 2020

The presented sketch on Norwid’s thoughts on independence takes into account only the statements of Cyprian Norwid after 1864, fol­lowing the fall of the January Uprising. As a starting point for discus­sion, the crucial 1869 text for the discussed issues was used: the epis­tolary essay Walka-polska, addressed to Agaton Giller. The main thesis of this essay is that Poles “know how to do battle” but “they cannot fight” and it is one of the main objectives of Norwid’s critical view on the Polish road to independence. Besides this essay, the above sketch brings back other texts by Norwid, important for the issues of inde­pendence. It discusses Odezwa w sprawie udziału Polaków w wojnie francusko-pruskiej [The call on the participation of Poles in the Franco- Prussian War] of 1870 and Odpowiedź Cypriana Kamila N. niektórym obywatelom o stanie rzeczy narodowej zapytującym [Cyprian Kamil N.’s answer to some citizens asking about the state of national affairs] from the period of Russo-Turkish War in 1877. These discursive texts are completed by a verse from Norwid’s poem Co robić? where the crucial question on the issue of independence is asked: “What to do in the dis­membered country.” Norwid’s comments on the meaning of spiritual independence, the importance of which could sometimes be more im­portant than independence understood only politically close the con­siderations included in this sketch.
Znaczenie muzyki kościelnej w historii Kościoła
Authors: Tyrała Robert
Published: May 2020

Jeśli spojrzymy na wieki istnienia Kościoła, to od samego początku dostrzeżemy prawdę o tym, że on nie mówił, ale śpiewał swoją mod­litwę – najpierw psalmami, następnie usystematyzował ją w dosko­nały sposób w chorale gregoriańskim, kolejno pojawiła się polifonia. W pewnym momencie dopuszczono do liturgii organy oraz inne in­strumenty. Dopiero w XX w. do liturgii wprowadzono w sposób ofi­cjalny śpiew wiernych podczas liturgicznych celebracji. Przez przeszło 2000 lat istnienia chrześcijaństwa ten muzyczny język był niezwykle bogaty i różnorodny, jak to zostało przedstawione w poniższym arty­kule. Zawsze też należy się wszystkim zatroskanym o kształt i jakość muzycznej szaty liturgii wdzięczność. Dlatego słowa na zakończe­nie nowej instrukcji Episkopatu Polski o muzyce są bardzo wymow­nym sygnałem do dbałości o jej jakość: „biskupi wyrażają wdzięcz­ność wszystkim zatroskanym o wysoki poziom muzyki kościelnej. Zobowiązują do zapoznania się z treścią instrukcji oraz starannego jej przestrzegania wszystkich odpowiedzialnych za muzykę kościelną w Polsce, w tym szczególnie duszpasterzy, organistów, katechetów, dy­rygentów zespołów śpiewaczych i instrumentalnych, członków chó­rów kościelnych, kompozytorów. Równocześnie zachęcają do twórczej współpracy wszystkich, dla których piękno liturgii jest nadrzędną ideą artystycznej działalności” (II IEP 65). Ważne jest zatem nie tylko od­działywanie i znaczenie muzyki w Kościele dzisiaj i w historii, stanowi ono także wyzwanie dla przyszłych pokoleń chrześcijan.

The Sweet War, or How Military Campaigns of Alfonso V of Aragon Affected the Eating Habits in Early to Mid-15th Century
Authors: Hryszko Rafał
Published: May 2020

Starting from the time of James I the Conqueror (1213-1276) the Kingdom of Aragon started its Mediterranean expansion. Following successive military expeditions, its conquests included: Mallorca and the other Balearic Islands (1229-1235), Sicily (1282) and  Sardinia (1323-1324). The culmination of this process was the involvement of a Alfons V the Magnanimous (1416-1458) in the war for the Kingdom of Naples, which began in 1420. After 22 years of intermittent struggle, in 1442, Alfons V the Magnanimous eventually captured Naples, which in the years to come became one of the leading centers of the Italian Renaissance.

The appearance of foreign domination in southern Italy suddenly entailed the transfer of Catalan culture, language and customs. Among the latter, Catalan culinary traditions formed at the end of the fourteenth century also occupied an important place. It was during this period that a significant change took place in the Kingdom of Aragon regarding the role and the circumstances of eating sweets by its financial and political elites. Until then, confectioneries were served as part of dessert at the end of the main meal (dinner or feast), while in the period discussed their consumption considerably shifted in time. Initially, their consumption was still associated with the various elements of the feasting etiquette (e.g. dancing, amusements, other meals). With time, the ceremonial of eating sweets transformed into a separate meal of sweet snacks, referred to by the Catalan term of col·lació. It quickly became a solemn, independently functioning type of feast, with an established ceremonial and setting.

Under what circumstances were Catalan eating practices transplanted to Italian context? What influence did the ruler and his military operations have on the enrichment of Italian feasting with new ele ments of Catalan provenance? – Such questions define the direction of the considerations made by the author of the paper.
From the Editors
Authors: Zinkow Leszek
Published: May 2020

The title subject matter of this Issue 27 of our quarterly “Perspectives on Culture” is likely to direct the Reader’s intuition toward philosophical re­flection. And rightly so. The basic dictionary definition of “identity” pro­vides one meaning of the term signifying a state of being identical, and further, implies the facts, features, and personal information allowing one to identify a person. However, a deeper, humanistic and social definition refers to the area of self-awareness, but also a sense of unity with the com­munity, and the elements that determine it. These elements are especially culture, values, and finally, the community itself as seen in the metaphysi­cal dimension, i.e., high moral and religious ideals. Two authors–philosophers, Agata Płazińska, and Piotr Duchliński from the Ignatianum Uni­versity, propose their reflections on the metaphysical and culture-building nature of self-sacrifice as represented by the lives and deaths of Edith Stein and Simone Weil, and the meaning of self‑sacrifice in the name of higher values. In our culture, such value might lie in giving one’s life for another human being. It is a kind of sacrifice which can be described as an abso­lute one. Contrary to the present crisis in metaphysics and axiology, such “absolute acts” are essential and indelible elements of identity in our cul­ture. In the second text, Fr. Mariusz Szram from the John Paul II Catholic University of Lublin goes back many centuries, to the time of the Fathers of the Church, to explore the theological reflection on creating a monu­mental cohesion of Semitic and Hellenic thought, defining the identity of Christianity. Two other interesting analyses in our title section are Chris­tian Identity of a Teacher of Early Education in the Contemporary World by Ewelina Kurowicka-Roman (KUL JPII) and Shaping the National Identity of the Youth in the Polish Scouting Association (ZHP) by Kamil Roman (also from the Catholic University of Lublin).
Ojcowie Kościoła o tożsamości teologii
Authors: Szram Mariusz
Published: May 2020

Celem artykułu jest przedstawienie modelowych cech, jakimi cha­rakteryzowała się refleksja teologiczna doby patrystycznej. Są to: nierozłączne ukierunkowanie na Boga i na człowieka; uznanie Pisma Świętego za najważniejszy punkt odniesienia każdej refleksji teolo­gicznej; umiejętność wykorzystania w tworzeniu podstaw teologii chrześcijańskiej elementów zaczerpniętych z obu kultur, w których otoczeniu pojawiła się nowa religia, zarówno semickiej, jak i helleń­skiej; dążenie do uporządkowania i zdefiniowania podstawowych prawd wiary dotyczących Trójcy Świętej i osoby Jezusa Chrystusa; zachowanie postawy pokory w procesie poznania Boga; wewnętrzna jedność i spójność myśli teologicznej; duchowa głębia myślenia i egzy­stencjalne utożsamianie się z wyznawanymi prawdami wiary. Powyż­sze cechy teologii, na które zwrócili uwagę Ojcowie Kościoła, decydują o jej tożsamości i mogą ożywić także dzisiejszy sposób jej uprawiania.
Significance of Strategic Alliances; the Case of Airline Alliances
Authors: Kopeć Ewa , Wolanin Artur
Published: May 2020

This article is poised to explain the significance, analyze and under­stand the relationships that are established between partners of a stra­tegic alliance. The analysis conducted was modeled on the example of airline alliances. Airlines decide on operating as alliances due to eco­nomic benefits which they would not be able to reach on their own. In the result of their cooperation, these entities produce beneficial syner­gistic effects. It should be noted that by starting cooperation within an alliance, those entities still remain competitors. The analysis provides a comparison of three largest airline alliances: Star Alliance, SkyTeam and Oneworld. The article contains a summary of the most important conclusions of the analysis.
Old Polish Writers and Freedom of Expression. Reconnaissance
Authors: Koehler Krzysztof
Published: May 2020

The paper discusses the question of freedom of speech as an impor­tant topic in old Polish literature. The author considers the problem of whether freedom of speech was one of civil liberties recognized by old Polish writers as characteristic for the political consciousness of the nobility in the early modern era. Discussing several cases (Fran­ciszek Karpiński, Wespazjan Kochowski, Jan Chryzostom Pasek, and Stanisław Orzechowski), the author indicates the inalienable relation­ship between the awareness of freedom of speech and the old nobility’s moral sentiments.
Seeing as Action. The Methods of Interpreting Visual Materials on the Example of Photography
Authors: Lebda Małgorzata
Published: May 2020

The article asks about the power of photography. Four photographs are referred to. The author tries to describe ways of looking, analyzing and interpreting each of them. Every time, it is a subjective analysis based on individual visual competences. The concept of punctum turns out to be important, as it allows a closer look at the visual. Ultimately, the answer to the question whether in the analysis of an image we take possession of it, or is it the other way around, is solved at the level of individual reception of a particular photo.
PECULIARITIES OF THE RUSSIAN LANGUAGE PRESERVATION
BY THE RUSSIAN SETTLERS’ DESCENDANTS IN CHINESE REGION
OF THREE RIVERS IN THE ХХ CENTURY AND AT THE BEGINNING
OF THE XXI CENTURY
Authors: Pustovalov Oleg
Published: May 2020

The territory of Trekhrechiye is the Region of Three Rivers (Sanhe, the District of Hulunbuir, Inner Mongolia, the People's Republic of China). This territory is subject to scientific study by historians and philologists. The research objects of this article are language aspects of modern Trekhrechiye. The aim of the study is to describe language competence of the Russian settlers’

descendants, who live now in the Region of Three Rivers, that place became mass residential centre of the Russian people in the XX century. Moreover, it is important to show dynamics of the people’s competences of the Russian language throughout the entire period of the Russian presence there. The description of the language competence of the Russian settlers’ descendants

of different generations is based on the results of scientific expedition to the Region of Three Rivers. The expedition took place in 2017–2018 and was undertaken by the author. It allowed the author to monitor the extent of the Russian language preservation in different generations.
INTENTIONAL LEXICAL MEANINGS
AS AN OBJECT OF RESEARCH
Authors: Kutsevich Yuliya
Published: May 2020

The article studies the linguistic research corpus, devoted to the expression of the meaning «volitional action» by means of the semantic structure of the lexical units representing the notion «intention». The main aim of the paper is to systematize

the comprehensive data on the topic under study, coined since the early XXth century to the present day both in Russian linguistics and abroad. Analytical description

of the theoretical sources is based on the five following criteria: the criterion of motivation for singling out a research object from the reality continuum, the criterion of terminology, the criterion of methodology, the criterion of categorial

features of the object, the criterion of semantic individuality discriminating parts of the object. The research results in the conclusion that the approaches to lexical volition

are isomorphic in terms of the most essential criteria – those of motivation for singling out a research object, methodology applied to it and its categorial features. Thus, in the papers considered the rationale for studying intentional lexical meanings

is their anthropocentricity, the universal method of surveying them is componential analysis; the studied categorial features include intentionality, prospectivity, purposefulness, and agentivity. The controversies in the authors’ perspectives are also brought to light and treated as an object of new research, requiring the respective theoretical corpus, systematized in the present paper.

Techno-Economic-Environmental Impact of Derating Factors on the Optimally Tilted PV System
Authors: Masrur Hasan
Published: May 2020

Solar-powered photovoltaic (PV) system encounters a signiﬁcant amount of losses due to different derating factors of PV modules throughout its lifespan. Thus, proper investigation is much needed to grasp the technical and economic impact of derating factors on the solar PV system, specially the one which is connected to the utility grid. This study performs a comprehensive discussion on various PV loss parameters followed by a techno-economic-environmental assessment of combined derating factor on an grid-connected and optimally tilted PV system located at Hatiya, Bangladesh using HOMER (Hybrid Optimization Model for Multiple Energy Resources) software. Some criteria linked with derating factor such as PV degradation and ambient temperature are further explored to analyze their impact on the aforementioned power system. Simulation results show that the system provides the best technical performance concerning annual PV production, power trade with grid, and renewable fraction with less emissions at a higher value of derating factor since it represents the lower impact of loss parameters. Similarly, ﬁnancial performance in terms of net present cost (NPC), levelized cost of energy (LCOE), and grid power exchange cost is found lower when derating factor value is higher.

PROBLEMS AND CHALLENGES FACING THE NEWLY SPLIT SOUTH SUDAN STATE
Authors: Adil Abdelaziz Hamid
Published: May 2020

This paper seeks to explore the possible problems and challenges facing the fledgling South State. It is this impartial approach to addressing such an issue that sets the current study as unique and exclusive.
The people of South Sudan have finally managed to establish their own nation state after almost two-decade of internecine civil war. In fact wars between the North and South were fought ever since the dawn of independence, and even before. The newly independent State of the South Sudan has to be prepared to put up with lots of agonies partly seen and predictable and partly not. There are myriad of models of split States across the globe, however the reality of the Southern State is enormously different. The South has for decades been a battle ground for several wars and hardly ever a developmental program started there was fully accomplished as it was planned, no matter how vital was the nature of that project.
The South is a land housing a multitude of ethnicities who disparagingly have their different set of cultural and social values with very slender common ground. The South, by its very tropical nature, provides a hospitable milieu for accumulation of diverse diseases. Positive aspects of independence as they shall form the future of the newly emerging nation shall receive their due analytical weight, as well.

KEY WORDS: split, corruption, social maladies, ethnicities, cultural and social values, hygienic awareness, newly independent

Use of Immuno-Oncology in Melanoma
Authors: Smylie M.G.
Published: May 2020

Treatment options for patients with metastatic melanoma have expanded rapidly since the approval of ipilimumab by the U.S. Food and Drug Administration in 2011. Cytokines such as interferon and interleukin-2 were approved in 1995 and 1998 respectively. However, the effect on survival was marginal, and the toxicity, substantial. Multiple vaccine studies likewise failed to show improvements in survival. The “Holy Grail” came with the discovery of immune checkpoints, and the first metastatic melanoma trial to show an improvement in overall survival involved the use of an immune checkpoint inhibitor against ctla-4: ipilimumab. Since then, the field of immuno-oncology has exploded, with approvals for PD-1 inhibitors and discovery, in clinical trials, of several novel checkpoints such as tim-3, lag-3, and others. In fact more than 950 novel immunotherapy drugs are currently being trialled. Recently, combinations of ctla-4 and PD-1 inhibitors have been associated with 1-year survival rates exceeding 80% and 4-year survival rates greater than 50%. In no tumour has as much progress been made in the last 5 years as in melanoma, and the efforts to unravel and exploit mechanisms used by the tumour to avoid immune detection are just beginning.

Adsorption behavior of tin phthalocyanine onto the (110) face of rutile TiO2
Authors: Bodek Lukasz , Engelund Mads , Cebrat Aleksandra , Such Bartosz
Published: May 2020

The adsorption behavior of tin phthalocyanine (SnPc) molecules on rutile TiO2(110) was studied by scanning tunneling microscopy (STM). Low-temperature STM measurements of single molecules reveal the coexistence of two conformations of molecules on the TiO2 surface. Density functional theory-based simulations (DFT) indicate that the difference originates from the position of the tin atom protruding from the molecule plane. The irreversible switching of Sn-up molecules into the Sn-down conformation was observed either after sample annealing at 200 °C or as a result of tip-induced manipulation. Room-temperature measurements conducted for a coverage of close to a monolayer showed no tendency for molecular arrangement.

Published: May 2020

Two previously undescribed dibenzocyclooctadiene lignans, named sieverlignans D–E (1-2), as well as eight known ones (3-10), were isolated from the aerial parts of Artemisia sieversiana. Their structures were elucidated from extensive spectroscopic analysis, including HRMS, NMR and circular dichroism experiments. This study is the first to report dibenzocyclooctadiene lignans in the genus Artemisia and this plant. All the compounds were evaluated for their anti-neuroinflammatory effects on the lipopolysaccharides (LPS)-induced nitric oxide production in BV-2 murine microglial cells. Compounds 1 and 6 exhibited the moderate activity with their IC50 values of 47.7 and 21.9 μM, compared to a positive control quercetin with the IC50 value of 16.0 μM.
New pharmacological means of radiation protection (literature review)
Authors: Uzlenkova Nataliya
Published: May 2020

The review systematized the current data on new classes of pharmacological compounds and biologically active substances in the field
of radiation protection in Ukraine, as well as abroad. Methodological
approaches and the importance of using appropriate animal models
in the development of new pharmacological drugs for radiation protection are described, specifically in the cases when it is impossible to
conduct full clinical trials on patients. Current views on the division
of pharmacological agents into radioprotectors, radiomitigators, and
therapeutic radiation protection agents are examined. The changes
in the hematopoietic tissue, gastrointestinal tract and neurovascular
system that occur after acute radiation exposure are also described.
Particular attention is paid to pharmacological agents that can protect against acute exposure to ionizing radiation by limiting the risk
of radiation mortality from the hematological and gastrointestinal
forms of radiation syndrome. Results of the effectiveness of tolerant
antioxidants with a wide spectrum of biological activity as promising
agents for the prevention of acute and delayed radiation-induced
pathology, in particular, in lung tissue, are presented. Possible molecular mechanisms of the radioprotective effect of pharmacological
compounds on experimental models of total and local radiation
exposure are discussed. The effectiveness of the therapeutic use of
growth factors and recombinant cytokines in acute bone marrow
suppression аfter accidental radiation exposure is shown. The possibilities of cell therapy with myeloid progenitor cells mobilized
by tocopherol succinate hematopoietic/progenitor cells and bone
marrow mesenchymal stromal cells in acute radiation injuries are
shown. Special attention is paid to the importance of improving such
methodological approaches and regulatory requirements when introducing into practice new radiation protection facilities in Ukraine.
Key words: radiation protection, ionizing radiation, pharmacological
agents, acute radiation syndrome.

Algorithm for the use of 12-month linezolid treatments in patients with pre-XDR tuberculosis
Authors: Feshchenko Yurii , Lytvynenko Nataliia , Pohrebna Maryna
Published: May 2020

The research was aimed to formulate a clear algorithm for the use
of short, 12-month, regimens, which consist mainly of linezolid, in
patients with pre-XDR, and to develop clear inclusion/exclusion
criteria and indications for the use of such on / off algorithms and
indications for the use in patients with extensively drug-resistant
tuberculosis (pre-XDR TB), based on the study of immediate and
remote treatment results.
Materials and methods. The “case-control” study included 90 patients with pre- MDR. For the treatment of patients in the main
group (35 patients), 6 anti-TB drugs were administered before
receiving the result of the TMC: linezolide (Lzd), levofloxacine (Lfx),
caproemycine (Cm), protionamide (Pt), cycloserine (Cs), pyrazinamide (Z). In cases of resistance to Ofloxacine (Ofx) or Km/Cm, Lfx
was replaced with moxifloxacine (Mfx), with the addition of high
dose of isoniazide (H). Such an intensive methodology lasted for a
period of 6 months, transitioning to the up-keep phase after a period
of 6 months without Cm. Patients in the control group (55 patients)
received individual chemotherapy of standard duration - 8 months
IF AMBT and 12 months PF AMBT, without linezolid.
Results. In patients with pre-MDR, who were administered
12-month shorter regimens, an increase in effective treatment by
41,6 % was found due to a reduction in the «lost of follow-up»,
«treatment failure» and «die» category. Relapse occurred only in 1,8
% of patients treated with the standard regimen without linzolid.
Conclusions. The use of algorithms for the appointment and selection of short, 12-month, regimens of linezolide treatment can improve the outcome of «effective treatment» in patients with pre-MDR
by 41,6 % compared to patients, who received standard treatment
without linzolid.
Key words: pre-XDR, short chemotherapy regimen, effective treatment.

levels of basal and postprandial glycemia,
and secretory state of basal and stimulated
C-peptide in the preclinical period of type 1 diabetes development in children and adolescents as immunological, metabolic and hormonal predictors of the clinical onset of the disease

Published: May 2020

Materials and methods. Based on clinical and immunological studies, in this study, we present data on the establishment of mechanisms that are responsible for the development of early and late pre-clinical stages of the type 1 diabetes (T1D), obtained by studying diabetes-associated autoantibodies (DAAb) and the levels of basal and postprandial glycemia, and C-peptide secretion at the preclinical stage of T1D development in children and adolescents.
Results. As a result we were able to form a group of marker-positive children with a genetic predisposition and an increased predicted risk of developing the diease. A total of 474 practically healthy normoglycemic children and adolescents aged 7 to 18 years were examined. An elevated titre of DAAb, mainly GADA and IA-2A was found in 94 (25.68 %) of 366 children with a genetic predisposition for at least of two determinants of DAAb, and the clinical onset of T1D manifesting in 68 (72.34 %) of them from 6 months to 15 years (30.9 ± 3.2 months). The formula of combined occurrence and values of simultaneously elevated titres of DAAb against islet autoantigens, namely, IA-2A + GADA, which is a predictor of the duration of the preclinical stage of T1D, was determined.
Conclusions. It was established that the early preclinical development of T1D in DAAb + children was characterized by the presence of dysglycemia in the form of elevated glycemia 2 hours after the glucose tolerance test and a steady decrease in the secretion of stimulated C-peptide; additionally, dysglycemia was jointed as impaired fasting glycemia, and there was a decrease in both basal and stimulated secretions of C peptide, indicating the depletion of the potential of pancreatic beta-cells.
Key words: type 1 diabetes (T1D), children and adolescents, diabetes-associated autoantibodies (DAAb), autoantibodies against glutamic acid decarboxylase (GADA), autoantibodies against tyrosine phosphatase (IA-2A), basal and postprandial glycemia, basal and stimulated C-peptide.

Published: May 2020

A través del análisis de estrategias narrativas bajo el prisma de diferentes teorías feministas, este artículo contextualiza la sutil subversión de los imaginarios visuales y textuales socio-sexuales hegemónicos que se exponen en Dolores, de Gertrudis Gómez de Avellaneda. La teoría feminista combinada con el análisis de las coordinadas socio-sexuales del periodo revela el carácter de resistencia y subversión del discurso del sistema romántico-burgués que se encuentra en esta novela de Gómez de Avellaneda y sugiere la intención de la autora de cuestionar la hegemonía de los códigos socio-sexuales de la época.

Comida, memória social e o encontro de gerações: a retomada do saber-fazer de uma receita de família
Authors: Oliveira Daniel
Published: May 2020

Este artigo propõe analisar os acontecimentos relacionados a necessidade de revisitar a receita de um bolinho crocante conhecido em uma região do estado do Piauí com mirrado. A demanda por fazê-lo surgiu em razão de uma antiga amiga da minha família, que estava distante há muitos anos, manifestar a vontade de voltar a sentir o sabor dele, pois era algo bastante significativo das suas lembranças de adolescência. O evento proporcionou um encontro intergeracional de algumas mulheres da família, com o propósito de retomar um saber-fazer que a passagem do tempo havia deslocado para o plano das incertezas. As observações e narrativas aqui apresentadas são utilizadas como dados etnográficos que colocam em evidência como vínculos familiares lidam com processos de transformações que atingem práticas culturais e, por consequência, afetam a memória social.
Maracatu nação em Pernambuco: raça, etnia e estratégias de enfrentamento ao racismo
Authors: Albernaz Lady Selma Ferreira , Oliveira Jailma Maria
Published: May 2020

Este trabalho trata dos sentidos e dos significados coletivos elaborados nos rituais de maracatu, especialmente focando as vestimentas, inicialmente elementos que retratam uma cultura negra e posteriormente, agregando-se referencias à África, remetendo mais claramente a etnização. O trabalho se ancora em trabalho de campo, realizado desde 2009. Analiticamente consideramos as dimensões de gênero e classe para pensar as questões raciais, e autores que tratam especificamente do racismo e seu enfrentamento no Brasil e nas Américas. Os resultados, com dimensões provisórias e sugestão de hipóteses interpretativas, sinalizam para uma continuidade na criação de uma cultura negra, que mesmo não sendo voltadas para o enfrentamento ao racismo, é uma ancoragem da organização do movimento negro recente, o qual, por sua vez propicia e a ampliação do conhecimento sobre a África e a inclusão de referencias a este continente por meio das roupas em alguns grupos de maracatu que remetem mais claramente a etnização.
