Authors: Kalinina Nataliya , Nosova Tetyana , Mamchur Stella , Tsokur Nataliya , Komarov Nikita
Published: December 2021

The effect of modification with dispersed compositions on the grain structure and mechanical properties of industrial aluminum alloys has been studied. Aluminum alloys of the Al-Si, Al-Mg-Sc, Al-Cu-Mn systems were modified with dispersed Mg2Si powder with a particle size of up to 200 nm. The amount of modifier to be added to the melt is calculated. The physicochemical properties of dispersed Mg2Si have been studied. Melting of the AMg6, 1570, 2219, AK9ch alloys in the initial state and with the treatment of Mg2Si melts have been carried out. The action of insoluble applications, isomorphic to aluminum, the similarity of the influence of soluble elements holds only when the amount of insoluble addition exceeds the number of crystals formed arbitrarily under the same conditions. Thus, with an increase in the amount of insoluble addition, in particular silicon carbide particles, the grain size first decreases and then remains constant. The mechanism of the influence of dispersed particles of magnesium silicide on the formation of the structure of hypoeutectic aluminum alloys during crystallization is that their bulk is pushed out by the crystallization front into the liquid phase and participates in the refinement of the structural components of the alloy. To determine the optimal amount of silicon carbide modifier, industrial melting and testing were performed on specimens that underwent heat treatment according to the T6 mode (quenching and artificial aging). The quality of cast aluminum alloys during modification depends on many factors: the nature of the dispersed phase, the temperature of the melt, and the modes of its mixing with the introduction of particles. Dependences of the particle size and the amount of the modifier on the mechanical properties of the alloys have been established. The mechanism of interaction of the modifier with aluminum melt during crystallization has been established. In industrial experiments, the most effective size of SiC particles for increasing the σm of the AK9ch alloy from 115 to 260 MPa in the as-cast state has been established. The optimal content of Mg2Si (0.10 %) for increasing the σm of aluminum alloys has been determined.

Published: December 2021

Due to the lack of 63.5 mm balloons in Ukraine in the first layout of Hop-900 hydraulic transmission sample, the balls of the PBG company (Precision Ball and Gauge Co., England) were used. However, the trials of hydraulic transmission showed increased wear and cracks on the surface of the balls. Goal. The purpose of the work is to increase the wear resistance of the units of a pump-controlled hydraulic drive. Methodology. The coating on the TICRN ball was carried out at the Bu-Lat-3T installation. The coating modes were chosen using a methodology for mathematical planning of an experiment by evaluating microhardness of molded coating and the material use factor. Metallographic studies of the structure of the materials studied and sprayed coatings were performed on the digestive and non-digestive grinds on the MIM-8M microscope. The phase composition of the spray coatings was determined on a Don-1.5 diffractometer in monochromatic CUKα radiation. Results. Following the wear resistance of all investigated materials showed the largest wear resistance of the balls with ion-plasma coating on the surface. Originality. The tests of the samples of radial ball-piston hydraulic transmission of GOP-900 type allowed to conclude that their reliability and further improvement is largely due to the reliability of the piston ball, to which there are high requirements for wear resistance, minimum volume of force and temperature deformation. Practical value. Taking into account the negative experience of using imported steel balls from chrome steel, positive experience of using balloons from Steel SH-15CG, mastered by the production of OJSC HARP, and at the same time, the need to increase the heat resistance and wear resistance of balls should be considered as promising research when using beads from powder, rapid steels of type P6M5F3-MP, ceramic balls having high strength properties.

Establishment of rational parameters of temperature of working liquid in the hydraulic drive of the excavator of the fourth dimensional group at different equipment
Authors: Pimonov Igor , Pohorilyi Igor , Fedyuchkov Maksim
Published: December 2021

The article considers the hydraulic drive of a modern excavator on which the influence of the working fluid temperature on the power is established, depending on the technical condition of the hydraulic elements. Studies have shown that new pumps and which have operating wear, have different rational temperature of the working fluid. It is impossible to imagine modern construction machines without equipping them with a hydraulic drive. The operation of the hydraulic drive largely determines the efficiency of operation of both a single machine and the entire fleet, which consists of new and old machines . The efficiency of hydrated machines is ensured in their design, manufacture, and operation, where an important role is played by the parameters of the working fluid: the degree of its contamination and temperature (viscosity). The influence of the temperature of the working fluid on the efficiency of the hydraulic drive and the ability to control the efficiency of the hydraulic drive with the help of temperature have not been studied enough. One of the promising areas in determining the rational temperature of the working fluid is the development of new designs of heat exchangers, heaters, diagnostic devices, which will be able to assess the technical condition of individual elements and the hydraulic drive as a whole. Establishing a rational temperature of the working fluid as a necessary parameter of the hydraulic system is mandatory when using modern methods to increase the efficiency of operation, maintenance and repair of hydraulic drives. With increasing temperature of the working fluid, its viscosity decreases and the loss of pressure and power in the mains of the hydraulic drive. However, this increases the internal flow of hydraulic units, which leads to an increase in power loss. Studies have shown that new pumps and which have operational wear, have different rational temperature of the working fluid. At rational values of temperature to the hydraulic motor the worn out pumps can give almost twice more power, than at 50 ° C, recommended for new pumps. The driving power of the pump, thus, practically does not change.
Influence of outpatient treatment newly diagnosed pulmonary tuberculosis on the development of familial tuberculosis (epidemic situation)
Authors: Duzhyi I.D. , Oleshchenko G.P. , Bondarenko L.A.
Published: December 2021

The incidence of tuberculosis in our country, according to statistics, seems to be declining. However, it should be remembered that the figures of the Crimean Autonomous Republic and the temporarily occupied territories of Donetsk and Luhansk oblasts are excluded from the digital data. Of particular concern are the significant worldwide morbidity and infant mortality rate of 700 people per day.The problem’s urgency is due to the data and the increase in the number of patients with common and destructive forms of pulmonary tuberculosis. The leading factor is the constant increase in the number of patients with multidrug­resistant conditions, the effectiveness of treatment of which does not reach 50%. In comparison, the WHO considers the critical limit for stabilizing the epidemic situation «effective treatment» at 85 %.

Objective — to study the features of familial tuberculosis on the background of outpatient treatment of patients with newly diagnosed tuberculosis.

Materials and methods. We observed 157 families with various forms of pulmonary tuberculosis. Radiation, bacteriological, immuno­genetic methods were used in the examination. Family members were examined every six months.

Results and discussion. Among the TB contacts after this period, tuberculosis was found in 162 people. Sources of tuberculosis (157) were bacillary in 49.7 %, TB contacts — in 43.8 %. Among patients in the group of heads of tuberculosis, there were 28 (35.9 %) people on MRTB, and in the group of TB contacts — 32 (45.1 %), р < 0.05. Thus, tuberculosis’s cause in TB contacts was not isolated from the family of patients with newly diagnosed tuberculosis.

Conclusions. Based on the results obtained, it is safe to say that if at least fixed bacillary patients were hospitalized, there could be no family TB contact patients. Comparing all sources of tuberculosis patients (157), it can be imagined that cases of familial tuberculosis (162) could be avoided. Nature «responded» to ignoring one part of the epidemic process (transmission of infection that increases with contact) by increasing the number of patients with familial tuberculosis by 5 people. We note: it was only about the Sumy region and only for a limited time.

Objective — to study the effectiveness of treatment of MDR-TB (multidrug-resistant tuberculosis) and preXDR-TB/XDR-TB (pre-extensively and extensively drug resistant tuberculosis), depending on the composition of ITRs (individualized treatment regimens).

Materials and methods. Тhe prospective observational study included 566 patients with MDR/preXDR-TB and XDR-TB during 2016—2020 on the scientific clinical bases of the SI «National Institute of Phthisiology and Pulmonology named after F.G. Yanovsky NAMS of Ukraine» and ME «Kryvyi Rih Anti-tuberculosis Dispensary» Dnipropetrovsk Regional Council Department. Patients were prescribed individualized treatment regimens in cases where short (standard or modified) regimens could not be prescribed. Patients were divided into comparison groups: 469 of them were treated with antimycobacterial therapy including bedaquiline and other effective antimycobacterial drugs groups A—C (without delamanid) — group 1. And 97 patients who were treated with the inclusion of both new antimycobacterial drugs (bedaquiline and delamanid) — group 2.

Results and discussion. Regardless of whether the delamanid, in addition to bedaquiline and other drugs selected for the scheme according to WHO recommendations, «effective treatment» was found in 91.3 against 88.6 % of patients. In the remote period (6-month — 4-year follow-up period) there was no recurrence of the disease, regardless of the composition of the regime. The loss of treatment effectiveness was due to deaths from non-tuberculosis reasons and those lost for follow-up.

Conclusions. For highly effective treatment, individualized regimens should include bedaquidine and linezolid from group A, and for previously ineffectively treated patients, clofazimine and carbapenems must be included (possibility to include 4 or more effective AMDs in ITR). For patients with fluoroquinolone resistance, treatment should include delamanid.

Piano Sonatas I–IV
Authors: Sapp Allen
Published: December 2021

This volume presents a critical edition of Allen Sapp's four earliest piano sonatas, the first written at just age nineteen while he was a student of Walter Piston at Harvard in 1941. Piano Sonatas II, III, and IV were completed while Sapp was on sabbatical from Harvard and living in Rome in 1957. The three Roman piano sonatas are remarkable in that they were composed using serial procedures, yet they were intentionally written to have strong tonal centers (especially the third sonata). Irving Fine, who gave the premiere performance of Piano Sonata I, composed an ossia of a passage in the second movement, which is included in the edition.

Exploring the Informal Communication of Driver-to-Driver on Roads: A Case Study of Durban City, South Africa
Authors: Adedayo Adedeji Jacob , Feikie Xoliswa E
Published: December 2021

Road traffic fatality is rated as one of the ten causes of death in the world and with various preventive measures on a global level, this prediction is only placed on flat terrain and didn’t reduce. Nevertheless, road users’ communication is an essential key to traffic safety. This communication, be it formal or informal between the road users is an important factor for smooth traffic flow and safety. Communication language on roads can be categorized into; formal device-based signal (formal signal), formal hand signal (formal signal), informal device-based signal (informal signal), and informal gesture-based signal (everyday signal). However, if the intent of the message conveys is not properly understood by the other road user, mistakes and errors may set in. Overall, the formal signal is based on explicit learning which occurs during the driving training and the license testing process and the informal, implicit learning occur during the actual driving process on the road unintentionally. Furthermore, since the informal signal is not a prerequisite to driving or taught in driving schools, novice drivers are clueless and thus, might have contributed to errors and mistakes which leads to traffic fatalities. Therefore, this study seeks to document the informal means of communication between drivers on South African roads. Consequently, a qualitative semi-structured interview questionnaire would be used in the collection of informal signals, which were predominantly used on South African roads from driving instructors and thereafter, a focus group of passengers’ car, commercial and truck drivers will be used to validate the availability and their understanding of these informal signals using a Likert-type scale for the confidence level. In conclusion, the information gathered from this study will help improve road safety and understanding of road users especially drivers on the necessity of communication and possible adaptation for other developing countries.

Published: December 2021

Background: Alveolar soft part sarcoma (ASPS) is a rare, slow-growing soft tissue tumor with uncertain etiology; it is considered among the least common sarcomas, representing 0.2-1% of these cases in large studies. These tumors usually appear during childhood or young patients, with predominance in females.
Case description: We introduce the case of ASPS in a 62-year-old man, who presented with 7 months of progressive headache and diplopia. The brain MRI showed an infiltrative lesion in the anterior fossa that extended to the right orbital roof. The possibility of metastasis was ruled out.  The patient underwent resection of the tumor with posteriorly good visual and neurologic recovery. Histologic characterization demonstrated homogeneous eosinophilic cells with a solid, vascularized pattern, cells with large and binucleated nucleoli, and vessels with endothelial and myoepithelial hyperplasia; numerous apoptotic bodies and mitosis figures were also present, but no necrosis. On immunohistochemistry, cells exhibited positive CD56, NSE in membrane form, and slight myogenin; vessels were strongly positive for myogenin, myoglobin, CD34, CD31, factor VIII, vimentin, and nestin as well as for HBM45, CD20, GFAP, and S-100; cytokeratin showed fine extracellular and intracellular filaments; GATA and TTF1 were negative.  Some clear cells were observed to be positive for CD68. The piece was diagnosed as a non-meningeal alveolar sarcoma of the soft tissue with solid pattern.
Discussion and Conclusion: This case corresponds to the second tumor of this kind presented at our institution, the first one reported, and perhaps, one of the oldest patients to develop it worldwide.
FAR-RIGHT VIOLENCE AND TERRORISM RISES IN GERMANY: NATIONAL SOCIALIST UNDERGROUND (NSU) TERRORIST GROUP AND THE MURDERS OF EIGHT TURKISH-GERMAN CITIZENS
Authors: Tulun Teoman Ertuğrul
Published: December 2021

Between 2000-2007, ten people were killed in Germany by unknown perpetrators. Four days after the explosion, the missing woman – later revealed as Beate Zschäpe – turned herself in. As the German authorities started to put the pieces together, they recognized that they had discovered the underground cell of at least three wanted neo-Nazis that had gone clandestine in the late 1990s. All in all, the NSU caused the most severe crisis of the German internal security system after the Second World War – a process called by the Federal Prosecutor General Harald Range Germany's 'September 11' in March 2012 (FAZ 2012). By now a total of ten assassinations, three bomb attacks and fourteen bank robberies between 1998 and 2011 were attributed to the NSU and the trial in Munich against the last surviving member – Beate Zschäpe – and the four most important supporters is already the most extensive terror trail in post-Second World War Germany. Instead, according to people who were at the meeting, he spoke extensively about the danger posed by far-right extremists and so-called Reichsbürger, a fringe group that rejects modern Germany and instead adheres to the old German Reich. This represented 'one of the biggest challenges' for Germany's security apparatus. It is quite unfortunate that nowadays we are obliged to talk about far-right domestic terror acts against politicians in Germany who are defending human values. It is time to stop sweeping the serious threats emerging in Western Europe under the rug and face the real problem. It is a fact that certain sections of the Western European societies are moving steadily to far-right quarters feeding from white supremacist and racist ideas.

A Hard-Science Approach to Kondratieff’s Economic Cycle
Authors: MODIS THEODORE
Published: December 2021

In an effort to evidence the Kondratieff cycle more scientifically than the way economists do, physical variables are studied rather than monetary indicators. Previously published graphs are reproduced and updated here with recent data. A cyclical rather regular variation of energy consumption reveals a 56-year cycle. A dozen human endeavors/phenomena, such as bank failures, homicides, hurricanes, feminism, and sunspot activity are shown to resonate with this cycle. Possible explanations for this phenomenon may have to do with a climatic variation or with the length of time any individual actively influences the environment. There is some evidence that the cycle may be getting shorter in amplitude and duration in recent years. All quantitative confidence levels involved in these observations are poor by scientific standards and permit critics to question the very existence of this phenomenon.

Published: December 2021

Sensitivity for rewarding cues and distress signals from children are fundamental to human caregiving and modulated by the neuropeptide oxytocin. In a functional magnetic resonance imaging (fMRI) study we investigated whether oxytocin regulates neural responses to reward or distress cues form children. In a placebo controlled within-subject design we measured neural responses to positive, negative, and neutral cues from children in 22 healthy female subjects who received oxytocin (24 IU) vs. placebo. Further, based on current literature, we hypothesized that oxytocin effects are modulated by experiences of childhood trauma. The task elicited valence specific effects, positive images activated the ventromedial prefrontal cortex, left anterior cingulate cortex and right putamen, and images of children in distress the bilateral amygdala, hippocampus and right medial superior frontal cortex. The effects of oxytocin depended on subjective reports of childhood emotional neglect. Self-reported neglect interacted with oxytocin administration in the amygdala, hippocampus and prefrontal areas. In individuals with higher scores of emotional neglect oxytocin increased neural reactivity of limbic structures to positive and neutral images. Our findings need replication in larger samples and can therefore be considered preliminary but are in line with the recent literature on the modulating effect of childhood adversity on the sensitivity to OXT administration.
Pupil Drift Rate Indexes Groove Ratings
Authors: Spiech Connor , Sioros George , Endestad Tor , Danielsen Anne , Laeng Bruno
Published: December 2021

Groove, understood as a pleasurable compulsion to move to musical rhythms, typically varies along an inverted U-curve with increasing rhythmic complexity (e.g., syncopation, pickups). Predictive coding accounts posit that moderate complexity drives us to move to reduce sensory prediction errors and model the temporal structure. While musicologists generally distinguish the effects of pickups (anacruses) and syncopations, their difference remains unexplored in groove. We used pupillometry as an index to noradrenergic arousal while subjects listened to and rated drumbeats varying in rhythmic complexity. We replicated the inverted U-shaped relationship between rhythmic complexity and groove and showed this is modulated by musical ability, based on a psychoacoustic beat perception test. The pupil drift rates suggest that groovier rhythms hold attention longer than ones rated less groovy. Moreover, we found complementary effects of syncopations and pickups on groove ratings and pupil size, respectively, discovering a distinct predictive process related to pickups. We suggest that the brain deploys attention to pickups to sharpen subsequent strong beats, augmenting the predictive scaffolding’s focus on beats that reduce syncopations’ prediction errors. This interpretation is in accordance with groove envisioned as an embodied resolution of precision-weighted prediction error.
Do disasters trigger protests? A conceptual view and review of the connection between disasters, injustice, and protests – the case of COVID-19
Authors: Vestergren Sara , Uysal Mete Sefa , Tekin Selin
Published: December 2021

People around the globe were and are affected by the highly contagious virus SARS-CoV-2 (Coronavirus, COVID-19) far beyond the virus itself. Despite the high viral transmission, people did not stop acting collectively. Sometimes these collective actions were against government regulations to health and safety (e.g., anti-lockdown), or to deal with systemic injustice and inequality affecting specific groups (e.g., Black Lives Matter). In this conceptual paper, we discuss the relation between protests and disasters. More specifically we discuss the crucial element of perceived social injustice and inequality for protest to emerge during or in the aftermath of disasters. We review literature related to disasters and protests before moving on to the COVID-19 pandemic to discuss how the context of COVID-19 can have influenced protests as well as protests’ potential impact on viral transmission. We demonstrate that protests during or in the aftermath of disasters are not uncommon. Furthermore, we suggest a direct link between emergent or increased perceived injustice and inequality and protests during/after disasters.

Published: December 2021

Using a Monte Carlo method, we simulate the measurement, by the 2E technique, of the average prompt neutron multiplicity as a function of the mass of fragments from the thermal neutron-induced fission of 239Pu. The input data for the simulation, associated with the primary fragment mass (A), consist of the yield (Y), the distribution of the total kinetic energy characterized by its average ((TKE) ̅) and its standard deviation (σ_TKE), the average prompt neutron multiplicity (ν ̅_s, a sawtooth approach of experimental data), and the slope of neutron multiplicity against total kinetic energy (dν_s/d). The output data, associated with the simulated as the fragment mass measured by the 2E technique (µ), consist of the yield (y), the distribution of the total kinetic energy characterized by its average ((tke) ̅) and its standard deviation (σ_tke), and the average prompt neutron multiplicity (ν ̅_µ). In the mass regions A≈115 and A>150, ν ̅_µ is higher than ν ̅_s. This result suggests that, in those mass regions, the 2E experimental values associated with the average neutron multiplicity are overestimated, referred to the corresponding to the primary fragments.

Published: December 2021

Hemogloin (Hb) and serum ferritin levels are used to assess anemia in pregnancy. Some studies referred to the influence of maternal age, body mass index (BMI) and parity on Hb and serum ferritin levels. The study aimed to examine the possible association of maternal Hb and serum ferritin with maternal age, parity, and BMI in a sample of pregnant women in Baghdad.

 Ninety healthy pregnant women, grouped in three equal groups according to the pregnancy trimester, and thirty apparently healthy non-pregnant women from Baghdad were enrolled in this observational study.  Blood and serum samples were obtained for the estimation of Hb and serum ferritin levels.

The pooled data of participants showed a negative correlation between parity and each of blood Hb concentrations (r= -0.147, P=0.046) and plasma ferritin levels (r= -0.186, P= 0.038). The negative correlation of parity with blood Hb concentration was reported in participants in the third trimester of pregnancy (r= -0.270, P=0.048); and between parity and plasma ferritin levels in the second (r= -0.088, P= 0.046) and third (r= -0.398, P=0.029) trimester pregnant. The study did not report a significant correlation between age and BMI with blood Hb concentrations or serum ferritin levels in pregnant women at any trimester of pregnancy.

There is a negative correlation between parity and each of blood Hb concentration and serum ferritin levels in pregnant women in Baghdad. While, there is no such correlation with maternal age and BMI at any trimester of pregnancy.

Published: December 2021

Drinking yogurt (ayran) is one of the valuable traditional Anatolian dairy products. Ayran is prepared traditionally through adding water and salt to yogurt or manufactured industrially by fermentation of yogurt culture added diluted milk. Nowadays, interest and consumption of traditional different fermented dairy products have spread rapidly around the world. Although cucumber-yogurt (cacik), soda ayran, fruitful ayran have a commercial face, there is still locally consumed drinking yogurt ayran types. One of the locally consumed ayran types is herby-hot ayran from Puturge-Malatya. In the preparation of herby-hot ayran, the flavoring herbs/spices are added to the ayran in earthenware pots then buried under the soil and left to ferment spontaneously for at least 15 days. The objectives of this study were to determine physicochemical, microbiological, and sensory properties of traditional purslane and/or Cayenne pepper added drinking yogurt from Puturge-Malatya, Turkey. The analysis results were found total dry matter 5.80-7.03 %, pH 3.77-4.30, titratable acidity 0.61-1.17 % lactic acid, serum separation 11.17-21.5 mL (50 mL)-1. Levels of lactic acid bacteria (LAB) ranged from 7.00 to 8.04 log cfu mL-1 and the mold and yeast (MY) levels varied from 5.25 to 6.98 log cfu mL-1 for studied samples. Properties of traditional herby-hot ayran are found different from plain ayran. The results demonstrated that this product may have the potential for consumer preference. To reveal the changes occurring in product characteristics during the fermentation period would be thus of interest.

Bu çalışmada, Yedikır Baraj Gölü (YBG)’nde yaşayan Tatlısu Levreği (Perca fluviatilis L., 1758)’nin yaş tayininde kullanılan omur ve otolit yöntemlerinin karşılaştırmalı analizinin yapılarak, yaş tayini için ideal yöntemin belirlenmesi amaçlanmıştır. Örnekler Aralık 2015 ve Nisan 2017 tarihleri arasında Yedikır Baraj Gölü’nden yakalanmıştır. Yaş tayini için 235 örnekten omur ve otolit alınmış, ayrıca seçilen 65 örneğe ait otolitler kesit alma tekniğine tabi tutulmuştur. Omur, bütün otolit ve kesit alınmış otolitte bir okuyucu tarafından 3 tekrarlı yaş okuması gerçekleştirilmiştir. Yaş tayini uyumunun tespit edilmesinde yüzde uyum (YU), ortalama yüzde hata (OYH) ve değişim katsayısı (DK) kullanılmıştır. Populasyon genelinde yaş dağılımı 0-5 yaş olarak gözlenmiştir. Baskın yaş sınıfı omur (%61.70), bütün otolit (%61.25) ve kesit otolit (%43.08) için 0 (sıfır) olarak hesaplanmıştır. Omur ve otolit yöntemleri karşılaştırıldığında en yüksek yüzde uyum %84.69 ile otolitte tespit edilmiştir. Bütün otolit-omur, bütün otolit-kesit alınmış otolit ve kesit alınmış otolit-omur yaşları karşılaştırıldığında, en yüksek yüzde uyumun bütün otolit ve kesit alınmış otolit arasında olduğu saptanmıştır (%78.5). Perca fluviatilis’in YBG populasyonunda yaş tayini için otolitlerin omura göre daha iyi sonuç verdiği tespit edilmiştir. Bütün otolit ve kesit otolit yöntemlerinden birinin tercih edilmesi gerektiği durumlarda ise bütün otolitin kullanılabileceği sonucuna ulaşılmıştır.

V. V. Repkin: contribuições para o desenvolvimento da teoria da Atividade de Estudo (1963–2019)
Authors: Amorim Paula Alves Prudente , Puentes Roberto Valdés
Published: December 2021

O artigo aborda as principais ideias do filólogo, filósofo, psicólogo, didata e metodólogo ucraniano Vladimir Vladmirovski Repkin (1927). O objetivo geral é apresentar os resultados da análise do progresso teórico-metodológico do pensamento e da obra de Repkin em relação à Teoria da Atividade de Estudo, a partir da avaliação das contribuições do autor para o desenvolvimento da teoria com foco em quatro aspectos relevantes: a) objetivo da Atividade de Estudo, b) conceito de Atividade de Estudo, c) conteúdo da Atividade de Estudo e, d) estrutura da Atividade de Estudo. Do ponto de vista metodológico, o texto se baseia no pensamento sistêmico, no método histórico-lógico, assim como na metodologia construtivo-interpretativa. As análises permitem concluir que o caráter autoral das teses de Repkin sobre atividade de estudo levaram ao surgimento de uma variante específica dessa teoria no contexto da aprendizagem desenvolvimental na Ucrânia.
JUDICIALIZAÇÃO DA SAÚDE
Authors: Guerra Helena Carolina Gonçalves , Santos Maria Celeste Cordeiro Leite dos
Published: December 2021

A saúde é um direito social e, como tal, pressupõe uma função dúplice do Estado: impedir que terceiros pratiquem atos restritivos contra o exercício do direito de outrem e, ao mesmo tempo, mitigar as disparidades existentes entre diferentes células da sociedade por meio da assistência social. Contudo, a ineficiência da ação positiva do Estado faz com que, muitas vezes, se recorra ao Judiciário para assegurar a efetividade desse direito, o que evidencia a importância de se estabelecerem critérios objetivos e isonômicos na avaliação de casos concretos. Entretanto, por vezes, a atuação jurisdicional acaba por acentuar o distanciamento entre diferentes classes sociais, conforme se demonstrará pelos casos concretos em análise neste estudo.
Gauchos, cowboys y malandros
Authors: Lima de Paula Raquel
Published: December 2021

Este artículo establece un diálogo entre tres figuras míticas y pintorescas (gaucho, cowboy y malandro) que habitan distintas expresiones culturales y revelan características identitarias y costumbres (la gauchada, el jeitinho) de los países involucrados (Argentina, Uruguay, Brasil, Estados Unidos). Se consideran los aspectos históricos, políticos y literarios que están por detrás de las representaciones de estos seres populares y al margen del sistema social. El objetivo principal de este análisis es mostrar como personajes literarios, seres inventados e imaginados, suelen ser utilizados para crear verdades y acciones político-sociales, que favorecen los de siempre y reproducen ideologías fosilizadas a lo largo del tiempo. Para tanto, este trabajo hace uso del referencial de la teoría literaria, de la sociología y de las narrativas que representan los tres tipos míticos nombrados, señalando que las obras literarias nombradas van más allá de la tradición mimética y refuerzan el carácter excavador, expansivo de la literatura, que tiene el poder de dilatar fronteras, por ser en sí una herramienta de descubrimiento (como lo es el arte en general).

OBJECTIVE

Effective use of social media (SM) by medical professionals is vital for better connections with patients and dissemination of evidence-based information. A study of SM utilization by different stakeholders in the brain tumor community may help determine guidelines for optimal use.

METHODS

Facebook, Twitter, and YouTube were searched by using the term “Brain Tumor.” Platform-specific metrics were determined, including audience size, as a measure of popularity, and mean annual increase in audience size, as a measure of performance on SM. Accounts were categorized on the basis of apparent ownership and content, with as many as two qualitative themes assigned to each account. Correlations of content themes and posting behavior with popularity and performance metrics were assessed by using the Pearson’s test.

RESULTS

Facebook (67 pages and 304,581 likes) was predominantly used by organizations (64% of pages). Top themes on Facebook, Twitter, and YouTube were charity and fundraising (67% of pages), education and research (72% of accounts), and experience sharing and support seeking (48% of videos, 60% of views, and 82% of user engagement), respectively. On Facebook, only the presence of other concurrent platforms influenced a page’s performance (rho = 0.59) and popularity (rho = 0.61) (p < 0.05). On Twitter, the number of monthly tweets (rho = 0.66) and media utilization (rho = 0.78) were significantly correlated with increased popularity and performance (both p < 0.05). Personal YouTube videos (30% of videos and 61% of views) with the theme of experience sharing and support seeking had the highest level of engagement (60% of views, 70% of comments, and 87% of likes).

CONCLUSIONS

Popularity and prevalence of qualitative themes differ among SM platforms. Thus, optimal audience engagement on each platform can be achieved with thematic considerations. Such considerations, along with optimal SM behavior such as media utilization and multiplatform presence, may help increase content popularity and thus increase community access to neurooncology content provided by medical professionals.
