Authors: Garzón Vásquez David Esteban , Toloza Villegas Jenny Alejandra , Villalobos González Gina Paola , Medina Barros Albeiro José
Published: January 2022

Se presenta una sistematización, realizada desde el Departamento de Estudios a Distancia de la Universidad Autónoma de Manizales (DEAD-UAM, Colombia), que muestra la experiencia de tres prácticas empresariales y sociales de los programas virtuales de las áreas de administración y negocios durante el periodo correspondiente al 2014-2020. Se realizó un estudio mixto de alcance descriptivo, el cual caracteriza los procesos utilizados por cada práctica, evalúa las secuencias didácticas digitales utilizadas y expone los principales resultados en términos de cobertura, población beneficiada y tipo de proyectos adelantados. Ante la escasa literatura en español relativa a las prácticas virtuales universitarias empresariales y sociales, esta experiencia muestra que la utilización del Modelo de Entornos Convergentes (MEC Complexus) permite hacer un uso intencional de TIC para construir secuencias didácticas digitales contextualizadas que faciliten las relaciones entre la universidad, la empresa y los territorios. De esta manera, las prácticas universitarias mediadas por TIC, bajo un modelo didáctico de soporte, recortan las distancias geográficas y permiten mayor accesibilidad, contribuyendo con el estudiante en el proceso de finalizar su ciclo educativo mediante el mejoramiento de sus competencias sociales y profesionales en contextos organizacionales reales.
"Eu só sei o que eu não quero", ou a arte como ritual: uma conversa com Getúlio Abelha
Authors: Dos Santos Renato Trevizano
Published: January 2022

Em uma conversa com o cantor, compositor e performer Getúlio Abelha, realizada virtualmente em agosto de 2020, refletimos sobre videoclipes cuir contemporâneos, tanto os de Getúlio, como Laricado, Tamanco de Fogo, Aquenda, Vá se Lascar e Sinal Fechado, quanto de outras artistas LGBTQs, incluindo Ventura Profana, Linn da Quebrada e Leona Vingativa. Estabelecemos ainda algumas relações com outros períodos e obras, como do Cinema Marginal e do underground norteamericano, com destaque para a figura de Divine nos filmes de John Waters. Além dessas produções audiovisuais, recorremos a alguns teóricos de referência para refletirmos sobre questões cuir, como Judith Butler, e a artigos contemporâneos sobre videoclipes, como “Vogue bike: cabra fêmea e outros horizontes subversivos nas paisagens do forró nordestino – a emergência de estéticas baitolas pelo artivismo” (Ribamar José de Oliveira Júnior e Leonardo Lemos Zaiatz, 2018), “Novas imagens da pomgabira na cultura pop: mitos, símbolos e estereótipos em circulação” (Florence Marie Dravet e Leandro Bessa Oliveira, 2015) e “Terrorismo anal em Anaconda de Nicki Minaj” (Fabrício Lopes da Silveira, 2015).

Memória e ação com o CachoeiraDoc: um festival de cinema com e como política pública
Authors: Cesar Amaranta , Costa Leonardo Figueiredo
Published: January 2022

Através de uma perspectiva descritiva e analítica endógena, o presente artigo oferece uma reflexão sobre o CachoeiraDoc - Festival de Documentários de Cachoeira, evento criado em 2010 pelo Grupo de Estudos e Práticas em Documentário (Gepdoc) da Universidade Federal do Recôncavo da Bahia (UFRB), em parceria com a Ritos Produções, produtora cultural baiana, na cidade histórica do interior da Bahia. Pioneiro no gênero no Nordeste do Brasil, o CachoeiraDoc se relaciona, desde sua origem, com políticas públicas em educação e cultura, que foram fundamentais para descentralização dos investimentos estatais nesses setores e, consequentemente, para a recente dinamização dos pressupostos epistemológicos que tem organizado esses campos de produção de saber. A partir de uma abordagem sócio-antropológica do cinema, nossa intenção é relatar a experiência do festival, a partir da materialidade política que o tornou possível, enfatizando as relações estabelecidas com instrumentos públicos de fomento e financiamento. Nos empenhamos ainda em esboçar um quadro conceitual através do qual seja possível pensar os festivais de cinema como política pública, a fim de oferecer, assim, uma contribuição para o novo campo de estudos de festivais no Brasil.

Um festival para as chanchadas? As conexões entre o Festival Cinematográfico do Distrito Federal e as comédias musicais (1953-1959)
Authors: Pinto Carlos Eduardo Pinto de
Published: January 2022

O artigo aborda a boa recepção obtida por algumas chanchadas ao longo da existência do Festival Cinematográfico do Distrito Federal. Criado por decreto em 1951 pela Secretaria de Turismo do Rio de Janeiro, com o objetivo de premiar obras que apresentassem uma visão atrativa da cidade, teve sua primeira edição realizada apenas em 1953, mantendo constância até 1959, penúltimo ano em que o Rio de Janeiro ocupou o posto de capital da República.  Em sete edições, o festival atribuiu o prêmio de melhor filme a quatro chanchadas, agraciadas também com troféus de melhor direção, argumento, roteiro e atuação. Tais dados chamam atenção por si, dada a visão negativa que imperava a respeito desse gênero entre a crítica especializada – o que os resultados das premiações permitem matizar. Contudo, os liames dos filmes com um imaginário sobre a capital, que era incentivado pelo governo federal por meio do concurso, também são levados em consideração, cogitando-se que o caráter “carioca” do gênero apresentava algum apelo às expectativas oficiais.
The three-dimensional impacts of governance on economic growth: Panel data evidence from the emerging market
Authors: Feyisa Habtamu Legese , Ayen Dereje Degu , Abdulahi Salah Mohammed , Tefera Frezer Tilahun
Published: January 2022

In a modern economy, good governance is considered a prominent factor for economic growth (Liu, Tang, Zhou, & Liang, 2018). However, Sub-Saharan Africa has a poor track record of good governance and economic growth (Fayissa & Nsiah, 2013). Therefore, this study is aimed to investigate the impact of governance on economic growth in Sub-Saharan Africa. Panel data that covers a period from 2005 to 2019 for 34 countries and the principal component analysis (PCA) method are employed to achieve the stated objective of the study. The selected fixed- and random-effect estimations showed that among the six-governance quality indicators control of corruption, government effectiveness, regulatory quality, and rule of law positively affect real GDP per capita (economic growth) while political stability and absence of violence and voice and accountability are statistically insignificant to affect real GDP per capita. The estimations result of composite governance indicators confirmed that except for the political dimension of governance both the economic and institutional dimensions of governance, as well as overall composite governance indexes, positively affect the economic growth of the region. Besides, foreign direct investment, the government fixed capital formation and gross domestic product growth affect real GDP per capita positively in all models while government consumption expenditure and age dependency ratio negatively affect real GDP per capita. Therefore, in addition to the existing support in the improvement of the political activities in Sub-Saharan Africa, concerned bodies should also focus to enhance the economic and institutional dimensions of governance in the region

In recent time digital imaging systems are the most commonly utilized technology in the field of radiology. The screen-film radiography systems are almost replaced by digital radiography. In which the image quality should be optimized while lower radiation dose is maintained according to the properties of the specific imaging system. Therefore, it is essential to regularly investigate image quality to ensure correct and accurate image interpretation assessment. This research is aimed to assess the factors that influence image quality and to recognize the different evaluation methods and their corresponding approaches that are used for system performance. Resolution describes the ability of medical imaging process to discriminate adjacent structures in organ tissues being examined. Signal from detected photon should be recorded with sufficient resolution in space, intensity and possibly time to produce a digital image that enables a medical interpretation of tissue structure and function. The anatomical and physiological characteristics of the region being imaged are considered to be the intrinsic factors of image contrast, which are called intrinsic, subject, object, or patient contrast. Low intrinsic contrast tissues such as breast tissues have very subtle differences in composition. In radiography, the physical properties of atomic number, physical density differences among different tissues and patient thickness influence intrinsic or subject contrast. Imaging methods and techniques are the second major factor which control image contrast. Will be more appropriate to select careful exposure techniques for specific tissues and for certain purposes greatly enhances image contrast to obtain the desired information. The only way to optimize image quality parameters while maintaining low radiation dose is to deeply understand the effects of these parameters on each other, the influence factors and their impact on the radiation dose for each different digital radiographic systems.[5] Keywords: Assessment, Image Enhancement, Radiology, Digital, Technology

Mobile Ad-Hoc Networks are infrastructure-less wireless communication technology that interconnects mobile devices such as phones, laptops, and smart devices including providing flexibility, seamless communication and mobility to all devices forming the network. MANET suffers security lapses due to the absence of central control infrastructure to monitor and control the devices that joins the network. These security lapses in MANET discourage it and makes it vulnerable to attacks such as denial of service attacks. Amongst various attacks prevalent on MANET environment, packet flooding is a common attack and causes a devastating effect on MANET nodes which if left undetected may lead to consequent crashing of the entire network. There is need to secure data and be kept confidential. In this paper, the separation of trusted nodes from malicious nodes and to protect the data packet from attackers is to be taken as research goal. Therefore, a highly secured Hybrid Trust-based Anonymous Authenticated Routing Protocol (HTBAARP) to mitigate flooding attacks is to be developed to avoid unauthorized access and to detect malicious nodes. This will be achieved by integrating a Modified Authenticated Anonymous Routing Protocol (MAASR) to a Trusted Management Scheme (TMS). Simulation will be done using NS-2 in conjunction with MATLAB R2020a to evaluate performance. The proposed solution is expected to improve throughput, packet delivery ratio and, reduces routing delay and routing overhead in the network.

Cloud computing is the practice of delivering on-demand computing resources such as servers, storage, databases, software, etc. This has created a paradigm shift in how things are being done by organizations regarding their IT operations. In some regions of East Africa, there is a decline in the level of Cloud computing. The study aims to provide an understanding of the status and trends for cloud computing in East Africa from several perspectives, including adoption, impact, and policy. The method utilized in the paper was a quantitative approach taken due to the existing literature reviews and case studies on cloud computing adoption in East Africa to provide detailed analysis so as not to limit the scope of the research for in-depth information. The result of this research describes how cloud computing is adopted in several East Africa countries and this will detail the current level of Cloud computing in the considered countries. Cloud computing was discovered to have been effectively adopted in the banking, marketing, education, and agriculture sectors as these sectors account for about 26%, 26%, 25%, 23% respectively. With the Agricultural sector being relatively the least. Although Cloud computing is not rapidly and readily adopted in East Africa, the result above shows that there is a fair adoption of Cloud computing in these sectors listed in the outlined countries.

This paper is focused on the use of technical personnel in the typical setting of a workshop in higher educational institutions in Nigeria. The essence is to fully manage tools for more creativity in technical work. The case study is focused on woodwork engineering management where vending cost analysis and implications model is presented to enhance productivity and reduction of requisition cost. So far, wood work refurbishing and repairs are being carried out with existing tools such as CNC-MDF Chain Saw Machine, and Automatic Edge Banding Machines respectively in quite a number of higher educational institutions in Nigeria. Now the trend has changed, more efficacious wood work requiring the production of durable stools and other furniture is needed. CNC works on the Cartesian coordinate system (X, Y, Z) for 3D motion control and parts of a project can be designed in the computer with a CAD/CAM program, and then cut automatically using cutters to produce a finished part. So these engineering trend has to be fully managed in such a way that the functionalities of these tools are fully harnessed to ensure full operations; particularly to produce for high-volume local content, skills acquisition and entrepreneurial development. The resultant effect will be to remove costly and repetitive manufacturing steps for office and other relevant furniture, and to create opportunities with future expansion for revenue generation.

Published: January 2022

The clarity of a river ecosystem and its ability to support and sustain aquatic life greatly depends on the quality and types of sediment it carries. The variation in the distribution of different categories of sediment could result in the changes in river channel formation and habitat. However, the paucity of information on the sediment quality of Gbalegbe River necessitated the investigation of its sediments characteristics dynamics. Gbalegbe River (12.5 km) was spatially stratified into eight sampling stations (S1, S2, S3, S4, S5, S6, S7, and S8) with reference to key anthropogenic activities. At each station, three sampling points were randomly chosen. Temporal stratification covered wet (March - October) and dry (November – February) seasons. Sediment samples were collected from each station forth – nightly for 24 months following standard methods. Sediment samples were analysed for Clay – %, Clay + Silt (CS –%), Organic Carbon (OC – mg.kg –1), pH, Cation Exchange Capacity (CEC – Cmol+.kg – 1) and Average Phosphorus (AP – mg.kg –1) following standard procedures. Data were subjected to descriptive statistic and ANOVA at α0.05. The highest (45.0) and least (20.3) Clay, CS (66.2, 35.3) were obtained in S2 and S1; OC ranged from 2.20±1.77 to 7.88±1.66 in S3 and S2; pH (4.30±0.93, 6.79±0.61) in S2 and S1; CEC (39.06±7.16, 108.59±34.43) in S1 and S6; AP (11.24±7.41, 41.83±22.78) in S3 and S8, respectively. Seasonally, Highest (45.8) and least (29.3) Clay; CS (75.0, 46.9) occurred in wet and dry seasons, respectively, while OC ranged 2.55±1.29 to 4.51±1.25; pH (5.61±0.89, 6.01±1.65); AP (14.49±1.79, 21.18±8.86) in wet and dry seasons, but highest (96.56±3.79) and least (91.04±3.67) concentrations of CEC were recorded in wet and dry seasons, respectively. The dynamics of sediments characteristics of Gbalegbe River are relatively unstable with Clay, CS, OC and pH. Therefore, its rich fisheries resources could be threatened.

Authors: Zhuang Pan , Liu Xiaohui , Li Yin , Li Haoyu , Zhang Lange , Wan Xuzhi , Wu Yuqi , Zhang Yu , Jiao Jingjing
Published: January 2022

OBJECTIVE: To
assess the relationship of circulating fatty acids (FAs) with risk of type 2
diabetes (T2D) and potential interactions with genetic risk.

RESEARCH DESIGN AND METHODS: 95,854
participants with complete data on plasma FAs from the UK Biobank, were
enrolled between 2006 and 2010, and were followed up to the end of 2020. Plasma
concentrations of saturated fatty acids (SFAs), monounsaturated fatty acids
(MUFAs), and polyunsaturated fatty acids (PUFAs) were analyzed by a
high-throughput NMR-based biomarker profiling platform. The genetic risk score
(GRS) was calculated on the basis of 424 variants associated with T2D.
Pathway-specific GRSs were calculated based on robust clusters of T2D loci.

RESULTS: 3,052 T2D cases were documented
after an average follow-up of 11.6 years. Plasma concentrations of SFAs and
MUFAs were positively associated with T2D risk while plasma PUFAs were
inversely associated. After adjustment for major risk factors, HRs (95% CIs) of
T2D for 1 SD increment were 1.03 (1.02-1.04) for SFAs, 1.03 (1.02-1.05) for
MUFAs, 0.62 (0.56-0.68) for PUFAs, 0.67 (0.61-0.73) for n-6 PUFAs, 0.90
(0.85-0.95) for n-3 PUFAs, and 1.01 (0.98-1.04) for n-6/n-3 ratio. Plasma MUFAs
had significant interactions with the overall GRS and GRSs for Proinsulin and
Liver/Lipid clusters on T2D risk. The protective associations of n-3 PUFAs with
T2D risk were weaker among individuals with higher Obesity GRS (P
interaction=0.040) and Liver/Lipid GRS (P interaction=0.012). Additionally,
increased plasma n-3 PUFA concentration was associated with more reductions in
T2D risk among participants carrying more docosapentaenoic acid-associated
alleles (P interaction=0.007).

CONCLUSIONS: Plasma concentrations of SFAs and MUFAs were
associated with a higher T2D risk whereas plasma PUFAs and n-6 and n-3 PUFAs
were related to a lower risk. Circulating MUFAs and
n-3 PUFAs had significant interactions with genetic predisposition to T2D and FA-associated variants.
Efficacy of Treatments for Cholestatic Pruritus: A Systemic Review and Meta-analysis
Authors: Dervout Charles , Boulais Nicholas , Barnetche Thomas , Nousbaum Jean-Baptiste , Brenaut Emilie , Misery Laurent
Published: January 2022

Cholestatic itch is a disabling symptom that may be secondary to liver or biliary diseases. Management of cholestatic pruritus is complex. A systematic review and meta-analysis on the efficacy of treatments for cholestatic pruritus were performed. PubMed and Cochrane Library were searched using the algorithm “(hepatitis OR cholestatic OR liver) AND (pruritus OR itch) AND (management OR treatment OR treatments)” for 1975–2019. Of the 2,264 articles identified, 93 were included in a systematic review and 15 in a meta-analysis (studies evaluating pruritus with a visual analogue scale). Some treatments act by reducing levels of pruritogens in the enterohepatic cycle, others modify the metabolism or secretion of these pruritogens, or act on pruritus pathways. A further possible treatment is albumin dialysis. However, due to many heterogeneities in the reviewed studies it is difficult to identify and recommend an optimum treatment. Only 15 studies were included in the meta-analysis, due to the small number of randomized studies using a visual analogue scale.
Effects of Adjacent Tooth Type and Occlusal Fatigue on Proximal Contact Force of Posterior Bulk Fill and Incremental Resin Composite Restoration
Authors: Oliveira LRS , Melo C , Cavalcanti KGBA , Soares PBF , Cardenas AFM , Soares CJ
Published: January 2022

Objectives

To measure the proximal contact force in newtons (N) between incremental and bulk fill class II resin composite restorations and implant molar teeth or adjacent premolar teeth with simulated periodontal ligament.

Methods

The model used was created with a typodont first molar tooth with two bilateral occlusal-proximal class II cavities, an adjacent tooth simulating an implanted molar tooth (Titamax CM, Neodent, Curtiba, PR, Brazil) and a premolar with simulated periodontal ligament. Two resin composite restorative techniques were used: Inc-Z350XT, (Filtek Z350, 3M Oral Care, St. Paul, MN, USA) inserted incrementally and Bulk-OPUS, (Opus Bulk Fill APS, FGM, Joinville, SC, Brazil) high viscosity bulk fill resin composite (n=10). As a control, a typodont having intact teeth without restorations was used. After the restorative procedure, each specimen was radiographed using a digital system (Dürr Dental, Bietigheim-Bissingen, Germany). The proximal contact force (N) was measured using dental floss with a microtensile machine (Microtensile ODEME, Luzerna, SC, Brazil). The specimens were then subjected to mechanical fatigue cycling to simulate 5 years of aging. All the parameters were measured after aging. The X-rays were blindly qualitatively analyzed by two operators to identify the loss of proximal contact. One-way ANOVA was used for comparing the initial contact force between restored and intact teeth. Two-way ANOVA followed by Tukey testing was performed for contact area data and for the contact force/contact area ratio. The proximal contact force data were analyzed using one-way repeated measurement ANOVA followed by Tukey testing (α=0.05). The X-ray proximal contact analyses were described by the frequency.

Results

The initial proximal contact force was similar for intact and restored teeth. The contact force and contact area with the molar were significantly higher than with the premolar; however the contact force/contact area ratio was similar for all tested groups. The bulk fill technique showed a contact force similar to the incremental filling technique. Fatigue resulted in a significant reduction in the proximal contact force (p<0.001), irrespective of the region analyzed or restorative material used. The digital X-rays detected no alteration in the proximal contact after occlusal fatigue.

Conclusions

Larger contact area resulted in higher proximal contact force. Proximal contact force decreased with 5 years of simulated occlusal fatigue. The bulk fill technique showed a proximal contact force similar to that of the incremental filling technique.
Os Processos Avaliativos no Ensino de Matemática e os Documentos Oficiais
Authors: França Alexandra Cristina Madeira , Andrade Maria de Fátima Ramos
Published: January 2022

Este artigo tem como objetivo investigar os processos avaliativos utilizados pelos professores, no ensino da Matemática, considerando as diretrizes da Base Nacional Comum Curricular e da Deliberação CEE 155/2017. Trata-se de um estudo de cunho qualitativo, descritivo-analítico, tendo como procedimento a realização de entrevistas semiestruturadas com professores que atuam numa escola particular. Apoiamo-nos, como referencial teórico, nos estudos de Telma Weisz que tratam das concepções de aprendizagem e de Hoffmann, Luckesi e Perrenoud que abordam o conceito de avaliação. Os dados coletados foram submetidos à análise e divididos em dois eixos: “fundamentos da ação docente e aprendizagem da docência” e “concepções de aprendizagem e os processos avaliativos”. Constatamos, com a análise, que os professores não definem qual a concepção de aprendizagem que sustenta suas práticas pedagógicas. Além disso, eles afirmam que conhecem os documentos oficiais - Deliberação CEE 155/2017 e a BNCC -, mas não os utilizam, preferindo seguir as normas avaliativas institucionais.

Authors: Rothenberger Eva
Published: January 2022

Le Dictionnaire historique et critique de Pierre Bayle est depuis longtemps considéré comme un des ouvrages clés qui a non seulement effectué une influence importante à l'époque de sa parution, mais aussi sur le siècle des Lumières par la suite. Le présent ouvrage examine, dans un premier temps, le dictionnaire en tant que genre littéraire et fait ressortir les particularités du Dictionnaire historique et critique. Dans un deuxième temps, on s'intéresse à la question de savoir comment des aspects formels du texte baylien permettent à l'auteur de propager des argumentation sceptiques. Par ce moyen, le rapport entre la forme et le contenu devient visible. Dans un troisième temps, on s'interroge finalement au même rapport entre la forme et le contenu mais en considérant la dimension historiographique de Pierre Bayle. Par cette étude, il devient possible de montrer que l'auteur se munit de certains outils de travail pour faire part de sa pensée en choisissant le dictionnaire comme genre pour son texte.

Hence, this study dealt with this sociolinguistic phenomenon and examine the impact of the Arabic diglossic situation in terms of social communication and the Arabic language learning process based on the second Arabic language learners’ perspective. The study starts with reviewing and discussing the literature by considering the Arabic diglossia from both linguistic and educational perspectives. To achieve the research objectives the researcher used mixed-method research namely, a close-ended questionnaire for quantitative data and open-ended questions for qualitative data. The sample included 26 students from different nationalities at the Arabic Language Center for Speakers of Other Languages at King Khalid University. The researcher concluded that the Arabic diglossic situation, especially the difference between the functionality of MSA (Modern Standard Arabic) and CA (Colloquial Arabic) is an impactful factor that can create an obstacle for the second Arabic language learners in terms of social communication in real context as well as the Arabic language learning process. The data prove that the second Arabic language learners in the Arabic Language Center for Speakers of Other Languages at King Khalid University are aware of Arabic diglossia and its impact on their social communication in real-life situations. Moreover, it was found that the Arabic diglossic situation slightly impacted their Arabic language learning process in terms of their desire to continue learning the Arabic language and the switching between MSA and CA that take place in the educational setting by some teachers

The article analyzes applying the machine learning methods for automated classification and routing in the ITIL library. The ITSM technology and the ITIL library are considered, the definitions to the incident and IT services are given. Further, the vectorization and extraction of keywords in the information written in natural language is carried out, for which lemmatization and the TF-IDF measure will be used. A comparative analysis of the application of machine learning methods, as well as a comparison of the results of automatic classification of text information using gradient boosting and a convolutional neural network is presented. Various parameters of these methods are considered. Gradient boosting showed the best results for the training and test sampling - 95% of correctly classified incidents; in cases with a neural network the result made 91%, a convolutional neural network had 92%. The accuracy of the handwritten classifier is 90%, as some of the incidents do not fall under its terms and remain unclassified. The results of the machine learning methods application for the automated classification of incidents make it possible to route requests for the restoration of the operability of IT services with high accuracy, to reduce the response time and errors associated with the human factor.

The effect of wind on the wires of overhead transmission lines leads to their vibration, as well as oscillations of different amplitudes. At places where the wire is suspended, damage to the metal structure of the fatigue type occurs. This is an excessive number of vacancies, dislocations, grain boundaries and blocks compared to the equilibrium one. The defective structure degrades in the direction of the formation of micro-gaps and cracks. The generation and development of the damage zone occurs from the surface of the wire. To prevent a rupture, it is necessary to monitor the development of this zone during the operation of the line without dismantling the wire. To improve the accuracy of assessing the level of accumulation of fatigue damage, the limiting states of the wire, it is recommended to develop methods based on measuring the electrical resistance of the wire material during the development of fatigue damage. A method for monitoring the state of the surface layer by measuring electrical resistance at high frequencies is proposed. The thickness of the controlled layer is determined by the frequency of the measuring signal due to the presence of a surface effect. For effective control, the depth of penetration of the field into the conductor must be commensurate with the thickness of the defective layer. For experimental research, samples were taken of a new wire and wires after various periods of operation on existing lines. According to the results of static tests, the tensile strength and the degree of nonlinearity of the tensile curve were determined. The results of experimental studies of fatigue strength and surface electrical resistance of a separate aluminum wire of A50 conductor are presented. The samples were tested for fatigue under loads close to the conditional endurance limit. The surface resistance of the wires was measured before and after fatigue tests in the frequency range 200 Hz – 2 MHz. The studies have shown the dependence of surface resistance on the degree of development of fatigue damage, which can be used to diagnose the accumulation of fatigue damage.
V.I. Chernyshev as Researcher of Russian Punctuation
Authors: Seagal K. Ya.
Published: January 2022

A generalization of the experience of research by Corresponding Member of the USSR Academy of Sciences V.I. Chernyshev (1867-1949) on Russian punctuation is presented. The polemic of V.I. Chernyshev with contemporary scientists A.M. Peshkovsky and G.O. Vinokur on the problems of punctuation is considered. The role of V.I. Chernyshev in the development of punctuation theory in Russian linguistics is shown. The relevance of the study lies in the fact that V.I. Chernyshev’s punctuation concept, which is the first experience of a functional approach to punctuation, is fully described. The novelty of the study lies in the fact that the analysis of segregation as a punctuation phenomenon is assessed. We found textual explanations for those uses of punctuation marks that are significant for the author’s style. The textual understanding of punctuation is revealed, the main principle in teaching punctuation is discussed. According to V.I. Chernyshev, the choice of a punctuation mark is based on semantics, correlated with the tradition of expressing a certain meaning by means of punctuation in the book language and with the aesthetic task of the author. V.I. Chernyshev’s ideas about the interaction of the author’s stylistics and textual criticism in the work of the editor on the punctuation of the artist of the word are described. Special attention is paid to individual examples of V.I. Chernyshev’s analysis of the use of punctuation marks in the works of A.S. Pushkin.

Authors: Kostetskaya E. V. , Suslova L. N.
Published: January 2022

The issue of reconstructing the image of Peter I on the pages of “Tobolsk Gubernskiye Vedomosti” is considered. The newspaper materials selected for the study reflect public opinion about the personality and transformations of Peter I and at the same time represent the source of Peter I image formation in the mass consciousness of the “Tobolsk Gubernskiye Vedomosti” readers. The purpose of the research is to study examples of the construction of the image of Peter I on the pages of the newspaper “Tobolsk Gubernskie Vedomosti”. Literary and comparative-historical approaches to the study of this problem are used. The analysis of the texts of newspaper materials published from 1857 to 1909 is carried out, and cases of mentioning the name of Peter the Great in the context of the events of all-Russian and local history are described.  The authors concluded that the newspaper participated in the preservation and consolidation of the name of the tsar and the events of his reign in the historical memory of Siberians. Examples of the formation of the image of an ideal ruler through various news reports of the newspaper “Tobolsk Gubernskiye Vedomosti” is considered in the study. It is proved that the newspaper supported the myth of Peter I as an idol, an enlightened autocrat, under whose reign Russia achieved prosperity and power. The publications of various genres reflect a positive attitude towards the tsar, as this corresponded to the policy of the official printed organ — the strengthening of monarchical ideals in the mass conscious-ness.
Sart-Kalmyks of Kyrgyzstan: a Brief Ethnographic Essay
Authors: Borlykova B. Kh. , Menyaev B. V.
Published: January 2022

In this article, based on published, archival and personal field materials of the authors (2009—2021), a brief ethnographic sketch of the Sart-Kalmyks of Kyrgyzstan is given. Sart-Kalmyks (Issyk-Kul, or Karakol Kalmyks / Kalmaks) are a relatively small Mongol-speaking people of Oirat origin who practice Islam. The article briefly examines the ethnonym “Sart-Kalmyk”, the history of the study of the Sart-Kalmyks, ethnic his-tory, ethnic composition, population, language, writing, economy, material and spiritual culture of the Sart-Kalmyks in the late XIX — early XXI centuries. Despite the paucity of sources, the authors tried to restore the ethnic origin and ethnic composition of the Sart-Kalmyks, which consists of more than twenty clans. During the expedition of 2021, the authors of the article found a copy of the manuscript of the “Kyrgyz-Sart-Kalmyk-Russian Dictionary”, compiled by S. S. Nasynbatov in the 1990s. It is shown that in the Sart-Kalmyk language words related to Buddhist vocabulary were found, which is evidence that they once included Buddhists. Particular attention is paid to the changes taking place in the modern life of the Sart-Kalmyks of Kyrgyzstan. It is concluded that the long-term residence of the Sart-Kalmyks in a different ethnic environment actively influenced the loss of their native language, writing, traditions and led to ethnic and ethno-cultural changes.

Published: January 2022

The features of the formation and development of wire broadcasting in the Buryat-Mongolian ASSR in the second half of the 1930s are analyzed. On the basis of previously introduced into scientific circulation and new archival documents, the authors prove that in the context of the organizational and technical strengthening of radio, the development of mass-political and cultural-educational propaganda, the state has made serious efforts to give the auditory means of communication the most important role of political and cultural education of citizens, increase their educational level and social activity. It is argued that at the end of the 1930s, the activities of the Republican Radio Committee for Radio and Broadcasting under the Council of People’s Commissars of the Buryat-Mongolian Autonomous Soviet Socialist Republic were characterized by its growing importance in the field of self-education of citizens, enlightenment and cultural and political propaganda. It is shown that serious work was carried out to create an effective broadcasting structure and differentiation of programs, special attention was paid to the organization of radio propaganda in the Buryat language. In describing the experience of the first five years of radio broadcasting in the republic, issues of staffing the radio committee, its close work with the department of cultural agitation and propaganda of the Regional Committee of the All-Union Communist Party of Bolsheviks are touched upon. It is noted that the most important results of this period were an increase in the volume of wire broadcasting, an improvement in the content of political, musical, literary, dramatic and other types of broadcasting.
