Published: March 2021

Objetivo: mapear as evidências existentes na literatura sobre os lutos vividos pelos profissionais de enfermagem durante a pandemia da Covid-19 e discutir sobre as repercussões para sua saúde mental. Método: revisão integrativa, cuja questão norteadora foi: qual o conhecimento cientí­fico produzido, até o momento, sobre os lutos vividos pelos profissionais de enfermagem em tempos de COVID-19? A busca foi realizada em novembro de 2020, nas bases de dados Pubmed, Cinahl, Scopus e Lilacs, utilizando os descritores Coronavirus Infections; Bereavement; Nursing; Mental Health, alcançando um total de 198 publicações. Após aplicados os critérios de inclusão e exclusão, obteve-se um corpus de 04 artigos. Resultados: Os estudos analisados foram realizados no Brasil e no Reino Unido.  Dois estudos investigaram aspectos da saúde mental no enfrentamento da Covid-19 especí­ficos para a equipe de enfermagem, um abordou todos os profissionais de saúde e o outro pesquisou os profissionais de saúde e a população em geral. Discussão: No enfrentamento da pandemia da Covid-19, as vivências do luto foram permeadas por sentimentos de medo, desamparo, desesperança, sofrimento moral, estresse, ansiedade, sintomas depressivos, Burnout e impotência, segundo os estudos analisados. Além disso, essas pesquisas traziam também algumas recomendações de proteção para a saúde mental dos trabalhadores, tais como: apoio por teleatendimento por enfermeiros especialistas em saúde mental e teleatendimento por psicólogos. Conclusão: A pandemia de Covid-19 tem gerado inúmeras mudanças na vida de todas as pessoas. Para os profissionais de enfermagem, a convivência diária com situações de luto faz emergir sentimentos que podem repercutir em sua saúde mental. Por ser um tema recente, ainda são escassos estudos que mostrem o real impacto da pandemia na saúde mental desses profissionais, apontando a necessidade de mais estudos que possam fundamentar ações de apoio ao luto durante a pandemia de Covid-19.

The purpose of the work is to determine in the Ukrainian society the scale of harm inflicted by drinkers to other persons, as well as the gender and age characteristics of this harm. In four regions of Ukraine (Kharkiv, Lugansk and Zaporizhzhia regions, Kyiv), during 2018-2020, 1,742 people were examined from three qualitatively different comparison groups: patients with alcohol dependence (393 people); their healthy relatives (274 people) and representatives of the general population (1075 people). The main research tool was the questionnaire of the international research consortium GENAHTO (Gender, Alcohol, and Harms to Others). It was shown that, in general, drinkers are present in the microsocial environment of 27.62 % of the surveyed healthy respondents. Extrapolation of this indicator to the entire population of Ukraine suggests that the total number of people who suffer in one way or another due to the drinkers in their environment is about 11.6 million people. In addition, the drinkers frequency in the environment of respondents can be used to determine the real number of people with alcohol problems in our country. Preliminary calculations indicate that this number is from 1.5 to 2.2 million people. The drinkers frequency in the environment of the respondents significantly depends on the age of the latter. The highest values of this indicator are characteristic of the respondents in the age category 40—59 years old” (31.43 % for men and 41.27 % for women). The subjective perception of harm from drinkers in the environment grows steadily with increasing age of the respondents, while this growth is most pronounced in women.

Aim: Substance use disorders (SUD) result in substantial morbidity and mortality worldwide. Opioids, and to a lesser extent cocaine, contribute to a large percentage of this health burden. Despite their high heritability, few genetic risk loci have been identified for either opioid or cocaine dependence (OD or CD, respectively). A genome-wide association study of OD and CD related phenotypes reflecting the time between first self-reported use of these substances and a first DSM-IV dependence diagnosis was conducted. Methods: Cox proportional hazards regression in a discovery sample of 6,188 African-Americans (AAs) and 6,835 European-Americans (EAs) participants in a genetic study of multiple substance dependence phenotypes were used to test for association between genetic variants and these outcomes. The top findings were tested for replication in two independent cohorts. Results: In the discovery sample, three independent regions containing variants associated with time to dependence at P < 5 × 10−8 were identified, one (rs61835088 = 1.03 × 10−8) for cocaine in the combined EA-AA meta-analysis in the gene FAM78B on chromosome 1, and two for opioids in the AA portion of the sample in intergenic regions of chromosomes 4 (rs4860439, P = 1.37 × 10−8) and 9 (rs7032521, P = 3.30 × 10−8). After meta-analysis with data from the replication cohorts, the signal at rs61835088 improved (HR = 0.87, P = 3.71 × 10−9 and an intergenic SNP on chromosome 21 (rs2825295, HR = 1.14, P = 2.57 × 10−8) that missed the significance threshold in the AA discovery sample became genome-wide significant (GWS) for CD. Conclusions: Although the two GWS variants are not in genes with obvious links to SUD biology and have modest effect sizes, they are statistically robust and show evidence for association in independent samples. These results may point to novel pathways contributing to disease progression and highlight the utility of related phenotypes to better understand the genetics of SUDs.

Published: March 2021

The present communication proposal is the result of an empirical research developed during the recording of the documentary “Ouro de Minas: a look at Luso-African-Brazilian cultural hybridity”, which addresses the tourist path from Belo Horizonte to Tiradentes, as a mediation proposal between the colonial past and contemporary social constructions. Therefore, the present article will seek to construct its own theory, multidisciplinary, hybrid and, therefore, legitimate representative of Cultural Studies, to propose a concept of digital image that is credible in the face of the contemporary challenge of a fragmentary, liquid and, above all, cultural reality. guided by network flows.
La pintura bajo el signo del Biopic
Authors: Vargas Manuel Rodríguez
Published: March 2021

When Ricciotto Canudo asserted: “We need Cinema in order to create the total art towards which all the others, since the beginning, have tended. The Seventh Art reconciles all others in this way”, everyone did not know to what extent these words would transcend. Thereby, cinema is always interested in a lot of themes, and one of them is art and artists, for this reason, it is not surprising then that a large number of painters have had a biopic, and all this had a great acceptance by the general public, because what until that moment was in the history books, could now be visualized through the big screen.However, artworks are not, in principle, too attractive material to elaborate a narrative so, it is common that biographical films about these great creators to pay attention to their mood swings, their often difficult character and the historical context in which they moved. So that, Michelangelo, Leonardo da Vinci, El Greco, Caravaggio, Vermeer, Rembrandt, Goya, Turner, Renoir, Van Gogh, Rodin, Modigliani, Dalí, Picasso, Frida Kalho or Pollock and their respective films will be studied and analyzed in this investigation. Thus, we are able to recognize and bring the talent of each of them, and the circumstances in which some of his most famous works were developed.
Metamorfoses – Um projeto de videoarte e fotografia.
Authors: Sobral Filomena Antunes , Simões Cláudia Figueiredo
Published: March 2021

Metamorphoses is a project whose objective is to induce introspective thinking about the search for perfection through the image. It refers to the existence of metamorphic gaze when the reflection of the self reproduces itself in the mirror: there remains the manifest contemplation of the individual as a reflected element and simultaneously a second surreptitious image created by the projection of the self. It is evidenced the artistic interpretation of the relationship of the subject with his reflection conditioned by social and cultural experience.Many artists use their own bodies to convey a message through image manipulation, and this is the focus of the Metamorphoses project. Therefore, this paper intends to present the results of an artistic project that establishes a symbiotic connection between photography and video art to show a self-representation which was distorted by the mirror in order to question the ideas of identity and perfection. The conception of metaphors is emphasized by the manipulation of sound and image and the constant presence of the mirror in photographic and video art creation wants to highlight the narcissus myth as a symbolic representation of the culture of the selfies.Thus, the article wants to divulge the experience of a scientific and artistic project that manipulates photography and video to communicate distorted transformations which an altered look may originate and that resulted in an art exhibition that reflects the structure of contemporary society in which the appearance and construction of Ideal images seem to be the foundation of the postmodern.
Speciesism | Ageism | Racism
Authors: Alves da Veiga Pedro
Published: March 2021

Speciesism | Ageism | Racism (SAR) is a generative cinematic artwork stemming from the millennia-old practice of mask making and laying claim to the fundamental richness of diversity. SAR generates sequences of masks from photos of people and animals without bias, imbued meaning or particular intent, leaving all interpretations and assumptions to the audience. SAR is aesthetically rooted in traditional folklore and the worldwide popular art of mask-making, in the concepts of “loop” and metric montage. Conceptually, SAR thrives in the intersectionality of postcolonial theory, feminist and anti-discrimination studies, as well as animal rights movements, policies and practices. By stripping away the ability to consistently identify species, age, race, gender or sexual orientation, the artwork allows for a disruptive aesthetic appreciation, which confronts the ideology and politics of group superiority. SAR delivers a participatory, hypnotic, rhythmic and generative audio-visual experience, charged with an anti-discriminatory message countering speciesism, ageism and racism.

Encontros, Festivais e Mostras - caminhos para construção do cinema negro brasileiro
Authors: Penha de Souza Edileuza , Mesquita Marcus Vinicius
Published: March 2021

The article seeks from the realization of the “Afro-Brazilian Cinema Moments Exhibition - Retrospective”, to analyze the process of consolidation of the concept of Black Cinema, and how the specific Encounters, Festivals and Exhibitions strengthened this process. Based on the questions about the image and the place of the black population in film production, we investigated the factors that led to the increase of production made by black filmmakers. In this way, we understand this process as a consequence of the racially defined public policies developed in recent decades, strengthened by the advance and access of new technological mechanisms and apparatuses of production; the establishment of the Association of Black Audiovisual Professionals (APAN); and also the outbreak of contemporary film festivals and shows, shaped around the racial issue in all regions of the country.
Entre oceanos e conhecimentos – o cinema documental na universidade
Authors: Santana Gilmar
Published: March 2021

Nowadays in several intellectual productions of the academic world in the fields of humanities, documentary film is an integral and simultaneous part of the processes and results of scientific research. Given the irreversibility of this fact, it is clear that dilemmas about its relevance still appear questioning its legitimacy as a tool, in itself, of knowledge. In this sense, from the testimony and reflection of five university professors who develop their research concomitantly with the imagery production in five different countries - Brazil, Cuba, the United States, England and Switzerland - this paper intends to debate how they present and articulate themselves: the presence of documentary cinema at university, its place as a producer and problematizer of knowledge, its support as a dialogical resource and its relevance as a sociological data in a world increasingly marked by the image as a vehicle of cultural practices.
Design & cinema: A timeline of graphic design in film
Authors: Tude Helena
Published: March 2021

Graphic design elements have always been part of cinema’s hybrid language, as a material of expression manifested through the visual channel, together with the filmed image. The graphic language is present throughout an entire filmic narrative, from the choice of verbal, pictorial and schematic elements in titles and animations, to the creation (and curation) of printed or handmade graphic props, signage and logos filmed by the camera. Together, they form a movie’s graphic identity, which aids in conveying meaning to the narrative as well as bringing a dynamic and authentic storytelling. This paper intends to present a timeline of graphic design in film by pointing out the technological milestones that shaped cinema’s development, directly influencing the emergence and disappearance of graphic configurations – which became more complex with time and affected the roles designers acquired in the film industry. By focusing mainly on examples from Hollywood’s contemporary cinema, the paper aims to show how the graphic language in films developed as an impact of technology reflected in society, which also leads to the identification of the three main functions acquired by the graphic language in narrative films nowadays.
O movimento das coisas: Jodie Mack e as animações experimentais em looping
Authors: Filho Wilson Oliveira , Falcão Gabriel Linhares , Malta Francisco
Published: March 2021

Since 2003, the english experimental director Jodie Mack has used primordial resources of cinema to produce cinematically powerful and entertaining works. With looping as the main artifice, her films explore different speeds, textures, colors, cuts, reflections, compositions and points of view. In movies like “Dusty Stacks of Mom: The Poster Project” (2013) and “The Grand Bizarre” (2018), the musical background is a constant. In the first, the director makes a rock opera adapting The Dark Side of The Moon to record the fall of the poster market, transforming the cultural products accumulated in her mother’s store into discard and consequently into raw material for her abstractions. The second is a roadmovie that moves around the raw material, mainly fabrics, tapestry pieces and maps that move around accompanied by music. Her movies stand out in contemporary experimental cinema for the uniqueness of having fun; experimentation is a great joke. Our aim is to analyze how Mack’s works dialogue with the looping of Eadweard Muybridge and Étienne-Jules Marey’s pre-cinema, with Stan Brakhage’s experimental provocations that encourage the exploration of movement, colors, textures and with animated GIFs. Despite the cinema’s proximity to GIF, it is not an easy task to point out names in contemporary cinema that relate to GIFs. Mack’s films are one of the few that can be seen as a series of GIFs and possibly the only one that, through a range of visual stimuli, manages to create movies as GIFs.
Sound in the Mise-en-jeu: Conveying Meaning through Videogames’ Mediated Space
Authors: Ribeiro João Pedro , Carvalhais Miguel , Cardoso Pedro
Published: March 2021

Mise-en-jeu is the ontological equivalent of film’s mise-en-scène. As such, mise-en-jeu is a cinematographic language through which game designers communicate. It offers designers the ability to create and shape the aesthetics of videogames’ mediated space, the space of the cinematographic presentation.Our prior work on mise-en-jeu focused on the visual aspects of videogames. With that in mind, starting with an analysis of mise-en-scéne, this paper provides an understanding of how sound is relevant for meaning-making through mise-en-jeu. Since videogames make use of some of motion picture’s filming techniques, we first studied practitioners and academics in the history of film, approaching videogames afterwards.The results of this research show that sound in mise-en-jeu allows designers to provoke emotions in players and to assist those players in formulating meaning as intended by the designers. We also found that mise-en-jeu allows for the deconstruction and interpretation of the characteristics of various variables of videogames’ mediated space. Therefore it allows us to understand better the relationship between videogames as audiovisual artefacts and the potential meanings that emerge from playing them.
Standing Ground: the index in the landscape of the digital
Authors: O’Sullivan Richard
Published: March 2021

This paper explores the intellectual background and production methodology behind the video Standing Ground (2019), a practice as research work that brings analogue and digital images into juxtaposition in a portrait of a derelict farmhouse. The accounts of three key theorists centred on the definition of photochemical photography and/or film through the indexical sign are discussed: André Bazin, Peter Wollen, and Roland Barthes. The paper then considers the work of scholars who have considered the implications of the transition to digital imaging for the indexicality of the image, including Lev Manovich and William Brown. In the light of this theoretical context, the paper reflects on the creative decisions made in the conception and production of Standing Ground, and considers the outcome of these decisions in the finished work. The paper concludes with an assessment of the methodology of the work in attaining the research aims of the project.
Hybrid Damage Prediction Procedure for Composite Laminates Submitted to Spectra Loading
Authors: Bousfia Mohammed , Aboussaleh Mohammed , Ouhbi Brahim
Published: March 2021

In this document, a hybrid procedure is constructed in order to predict the damage of a composite unidirectional laminate under random loading. This procedure is based on two pillars: a stiffness degradation model (SD-M) combined with an energy approach taking into account the effect of load ratio in addition to a system of equations generated by SSDQM method (Space State Differential Quadrature Method) which we have solved with a novel technic. The outputs of SSDQM method, previously serving for free vibration behavior analysis of composite structures, are used with those of SD-M model to predict damage failure of a composite laminate subjected to spectra loading. The results obtained correlate very well with experimental ones and an extensive comparison with other models validate the accuracy and convergence characteristics of this hybrid procedure.

The economy of the Murmansk region retains its raw material orientation, as it is justified by the region’s natural resources and industrial potential. Economic activity of mineral-resource enterprises and those mining ores of ferrous and non-ferrous metals is going to remain the dominant sector of the regional economy for a long time due to the geological and economic characteristics and natural and climatic features peculiar to this area. The region is endowed with various natural resources. On the Kola Peninsula there are more than sixty major deposits of various types of mineral raw materials with more than three dozen extractable resources, the most valuable of which include copper-nickel, iron, apatite-nepheline ores and ores of rare metals. Production management and transportation of raw materials require well-developed infrastructure, creating an integrated transport system, that is why it plays a strategic role in the economy of the Murmansk region. It is connected with the fact that the region is predominated by industries focused on producing and delivering considerable volumes of raw materials and metals outside the region. In these circumstances, every enterprise plans and arranges transportation of cargo by various means of transport. Railway transportation plays a significant role as it provides round-the-clock cargo transportation from senders to recipients fulfilling clients transportation requests regardless of weather conditions.Therefore, the important scientific task is analyzing the cargo base and finding solutions for improving the existing and creating new designs of wagons and containers for railroad transportation of cargo, taking into account spatial directions of cargo flows, which is the purpose of this article. The authors have proposed options for modernization of wagons and designs of composite containers that possess scientific novelty, as the current state of the railroad transport system requires modernization.It is impossible to achieve effective economic performance of an enterprise that works in the sphere of mining and processing of mineral raw materials without creating a proper transport component that requires its own development. The implementation of the given proposals will allow the enterprises to increase the volume of cargo transportation which in its turn is going to have a significant impact on socio-economic development of the region.

Pulsation spurts of clusters determining nanocurrent ferroelectric electricity of gel tin oxyhydrates are shown experimentally, which characterizes macroscopic quantum coherent effects induced by a nonstationary magnetic field in the dynamics of high-spin magnetic nanocurrent clusters in a gel matrix. The polyhedral Coxeter model of the tin oxyhydrate Pattern, which is used to make gel objects, is considered, and specific cluster structures are calculated. The experimental geometry of Coxeter polyhedra is described by a gram matrix, where the values of the matrix are cosines of the slope angles of the faces of WHITNEY oxyhydrate structures. Matrix description of the structure of the oxyhydrate, for example, for 42 days (165-231 min.) of aging, allowed to quantify the structural features of polyhedra or the so-called Whitney folds, which form the electromagnetic wave fronts of energy caused by nanocurrent polarization of oxyhydrate polyhedra. Quantitatively, the Whitney folds are determined by calculating the trace or hole of the corresponding gram matrix. The Coxeter polyhedra of the oxyhydrate gel are constructed mainly from cluster five-vertices, which in time can compete isomorphically with the facet 30, 20, 14, 12, and 6 vertices. This determines the fine structure of the gel axiology conformations during aging. The probability of the formation of 30 vertices in the gel of tin oxyhydrate is one of the highest.

Combined heat and power plant (CHP) are sources of environmental pollution and therefore requires continuous control of the flow of pollutants which are generated during their work. One of the leading CHP in the city of Kirov (Kirov region, Russia) is a CHP-5 located in the South-Western outskirts of the city. The aim of the study was to assess the degree of anthropogenic load and the territorial focus of the impact of CHP-5 on the natural environment according to the results of chemical analysis of snow. As indicators of contamination used in the mass concentration of ions of sodium, ammonium, potassium, magnesium, calcium, strontium, zinc, cadmium, lead, copper, fluoride-, chloride-, nitrate-, phosphate- and sulfate-ions; the concentration of polycyclic aromatic hydrocarbons (PAH) in solid phase of snow water, acidity and electrical conductivity. It was found that the samples of snow water in areas near CHP-5 had a content of inorganic ions and PAHs exceeding the background values. The higher content of ions and heavy metals (HM) differed from forest sites in comparison with meadow. The highest concentrations of sodium, ammonium, potassium, calcium, magnesium ions, more alkaline reaction of the medium are determined in the snow water of the leeward areas of CHP-5. In comparison with background sites, the highest content of HM ions in snow water was found in samples from sites in the South-West direction from the CHP near the place of storage and transportation of coal. The most polluted PAHs are the areas located on the leeward side of the CHP and near the Sovietsky tract. The carcinogenic activity of PAHs in the solid phase of snow water is quite high and varies from 6.79 to 9.71 µg/dm3. Maximum electrical conductivity, high concentrations of potassium, calcium, copper, lead, zinc, chloride, nitrate, sulfate ions, increased content of pyrene relative to background, benz[b]fluoranthene, benzo[a]pyrene and benzo[g,h,i]perylene is set for the forest area (4-S-W), located in the south-western direction from the CHP, in the immediate vicinity of storage and transportation of coal. This site is the most polluted of all investigated, the degree of its pollution can be characterized as an average.
