Competitive strategies for international marketing of hardwood products based on the mining of open questionnaire data
Authors: Arias Edgar , Quesada Henry , Smith Robert L.
Published: July 2021

International markets for U.S. forest products continue to make a significant contribution to the national economy; sustaining growth in production and job creation as demand from domestic markets is still yet to match that observed during the early 2000s. In this context, industry, government, and academia remain focused on procuring better market shares in foreign markets. The goal of this research is to help hardwood mills to improve their understanding of the needs of potential clients abroad and thus helping them to develop a competitive advantage. An exploratory study based on text mining of questionnaire data was conducted following a competitive criteria-based model on the major foreign markets for U.S. hardwood products. From a sample of buyers attending trade shows in Asia and Europe, this work has identified a series of factors for manufacturers to consider in future export ventures. It was determined that price and quality play multiple roles in developing a competitive advantage. Color-consistency and an adequate stock of the right mix of species are considered minimum requirements to compete in those markets. In contrast, certain time-compression dimensions are perceived as opportunities to add value and, therefore, to stay ahead of the competition.

Composite nanofibre polyvinyl alcohol (PVOH) was prepared in this work reinforced with nanofibrillated cellulose (NFC) using an electrospinning technique. NFC was isolated from oil palm empty fruit bunches (OPEFB) by steam explosion method followed by acid hydrolysis. A 12 wt% PVOH solution in distilled water was prepared under constant reflux at 80 ºC for 5 h. Several concentrations of NFC were added to the polymer solution of 2.5, 5.0, and 7.5 wt%. The nano-dimension of NFC was analysed using transmission electron microscopy (TEM). The morphology of electrospun nanofibre was characterised using scanning electron microscopy (SEM). The morphology of PVOH nanofibre was smooth and uniform without beads. The presence of NFC in the PVOH nanofibre decreased the diameter. The morphology of PVOH/NFC nanofibre at a concentration of NFC 2.5% was fairly uniform with good quality. However, the preparation of PVOH/NFC nanofibre at concentrations of NFC 5.0% and 7.5% resulted in elliptical beads. The crystallinity of NFC and electrospinning nanofibre was investigated using X-ray diffraction (XRD). In addition, the thermal properties of the samples were analysed using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results showed that NFC improved the thermal stability of electrospun PVOH nanofibre.
Dostoevsky's Garibaldi: additions to the commentary
Authors: Shvarts Natalia
Published: July 2021

This study is a contribution to the research of the extensive topic of Dostoevsky and Garibaldi and is an analysis of two fragments from Dostoevsky's texts, where he addressed the image of the Italian hero. This image is reflected in the artistic, journalistic and epistolary texts by Dostoevsky, his name is calligraphically printed on the pages of two of the writer's notebooks. The article analyzes an episode from the novel "The Idiot": the story of the liar and braggart General Ivolgin about his wound during the Crimean War that was treated by two outstanding surgeons – the Frenchman O. Nelaton and the Russian N. I. Pirogov. It is shown that the subtext of Ivolgin's story refers to the story of Garibaldi's wound in the battle of Aspromonte and the treatment of his leg by O. Nelaton and N. I. Pirogov, which Dostoevsky and his hero learned about from the newspapers. The European and Russian press, which closely followed the political events in Italy and Europe in the 1860s, created a heroic image of this man. The second reference to Garibaldi is from Dostoevsky's Geneva letter to his niece S. A. Ivanova dated January 1 (13), 1868. It presents a parody sketch of contemporary political events and figures in Italy (Cardinal Antonelli, General Kanzler, the defeat of Garibaldi's army at the Battle of Mentana). They are allegorically transferred to the games and amusements of the younger generation of the Ivanov family, with whom the writer spent the summer of 1866. The article corrects the error made by the publishers of Dostoevsky's letters: the title of "general kanzler" (this is how this phrase was published) never existed — in the Battle of Mentana, the supreme commander of the papal troops, which defeated Garibaldi, was General Hermann Kanzler, who had a German origin and surname. The cases considered indicate a significant interest of the writer in the heroic personality of Giuseppe Garibaldi, his activities and fate.
AN APPROACH WEB SERVICE SELECTION BY QUALITY CRITERIA BASED ON SENSITIVITY ANALYSIS OF MCDM METHODS
Authors: Polska O. V. , Kudermetov R. K. , Shkarupylo V. V.
Published: July 2021

Context. The problem of QoS based Web service from the list of Web services with equal or similar functionality was considered. This task is an essential part of the processes of finding, discover, matching and using Web services on the Internet due to the numerous offerings of Web services with equal or similar functionality. The reasonable selection of a suitable Web service takes into account a lot of user’s quality requirements, such as response time, throughput, reliability, cost, etc. Such a task is usually formulated as an MCDM problem, in which the parameters are the Web service quality factors and the importance degree of these factors. The object of this research is a process of selection Web services using MCDM methods, taking into accounts the user’s preferences and requirements to the Web service quality characteristics. The subject of the research is the LSP method, which, in addition to the degree of importance of the criteria used in all MCDM methods, simulates the user’s reasoning about quality, taking into account, in particular, such characteristics of the criteria as mandatory, sufficiency, desirability, simultaneity and substitutability.
Objective. The objective of the work is to develop an approach for comparing the result of using the LSP method with the results of using other MCDM methods.
Method. A method for calculating the weights of input criteria that are not always explicitly specified in the LSP method was proposed. For this, the conjunctive coefficients of impact are used, which are calculated as a result of the sensitivity analysis of the Web service generalized quality criterion to changes the partial quality criteria. This method underlies the proposed approach to comparing the efficiency of the LSP method with other MCDM methods, which consists of using the obtained weights as the weights of the input criteria for the MCDM methods.
Results. The developed method and approach was verified experimentally. The Web service ranking produced by the LSP method was compared with the ones produced by SAW, AHP, TOPSIS and VIKOR methods. This comparison confirmed the efficiency of the proposed method and approach.
Conclusions. From the obtained results of comparing the LSP method and the MCDM methods considered in this study, it follows that the proposed method and approach provide the equivalent input conditions for these methods as for the LSP method, which is a necessary condition for the correct comparison of MCDM methods. The use of the proposed approach made it possible to study the sensitivities of the considered MCDM methods. In practical applications, this approach can be used to select a suitable MCDM method. The proposed method can be useful for creating professional evaluation systems in which it is necessary to assess the importance (weights) of tens and hundreds of quality criteria.
EXPERIMENTAL ANALYSIS OF MULTINATIONAL GENETIC ALGORITHM AND ITS MODIFICATIONS
Authors: Gulayeva N. M. , Yaremko S. A.
Published: July 2021

Context. Niching genetic algorithms are one of the most popular approaches to solve multimodal optimization problems. When classifying niching genetic algorithms it is possible to select algorithms explicitly analyzing topography of fitness function landscape; multinational genetic algorithm is one of the earliest examples of these algorithms.
Objective. Development and analysis of the multinational genetic algorithm and its modifications to find all maxima of a multimodal function.
Method. Experimental analysis of algorithms is carried out. Numerous runs of algorithms on well-known test problems are conducted and performance criteria are computed, namely, the percentage of convergence, real (global, local) and fake peak ratios; note that peak rations are computed only in case of algorithm convergence.
Results. Software implementation of a multinational genetic algorithm has been developed and experimental tuning of its parameters has been carried out. Two modifications of hill-valley function used for determining the relative position of individuals have been proposed. Experimental analysis of the multinational genetic algorithm with classic hill-valley function and with its modifications has been carried out.
Conclusions. The scientific novelty of the study is that hill-valley function modifications producing less number of wrong identifications of basins of attraction in comparison with classic hill-valley function are proposed. Using these modifications yields to performance improvements of the multinational genetic algorithm for a number of test functions; for other test functions improvement of the quality criteria is accompanied by the decrease of the convergence percentage. In general, the convergence percentage and the quality criterion values demonstrated by the algorithm studied are insufficient for practical use in comparison with other known algorithms. At the same time using modified hill-valley functions as a post-processing step for other niching algorithms seems to be a promising improvement of performance of these algorithms.
Impact of obesity on echocardiographic parameters and N-terminal pro-brain natriuretic peptide levels in patients with heart failure with mid-range ejection fraction: unanswered questions

Aim. To analyze and compare the clinical, echocardiographic characteristics and serum N-terminal pro-brain natriuretic peptide (NT-proBNP) levels depending on the central cardiometabolic risk factors, with a focus on obesity, in patients with heart failure (HF) with mid-range ejection fraction (HFmrEF).

Material and methods. The study included 111 patients with old myocardial infarction and HFmrEF (men, 100%; mean age, 60 years) predominantly of NYHA class II. Echocardiography and blood sampling for NT-proBNP were performed with sinus rhythm. Left atrial volume (LAV) and left ventricular mass (LVM) were indexed to body surface area (BSA) and height raised to a power.

Results. Type 2 diabetes, overweight and obesity were diagnosed in 25%, 19%, 38% of cases, respectively, and were associated with greater changes in the morphologic and functional left ventricular parameters. There were no intergroup differences among patients with and without obesity in the LAV and LVM indexed to BSA. However, in patients with a body mass index (BMI) ≥30 kg/m2, the LAV indexed to height squared and LVM indexed to height2,7 were higher (p<0,05 for all). In 11% of obese patients, there were no changes in the criterion LAV or LVM values indexed to BSA, but the values indexed to height raised to a power exceeded the standard values. In 20% of patients with clinical manifestations of stable HFmrEF and structural and functional echocardiographic criteria, NT-proBNP were ≤125 pg/ml. An inverse correlation was found between NT-proBNP and BMI (r=-0,29; p=0,008), and lower values of myocardial stress marker were observed in obese patients (p=0,048).

Conclusion. Considering the high incidence of obesity in patients with HFmrEF and its ability to reduce NT-proBNP, an algorithm modification is required for diagnosing HFmrEF as follows: focus on clinical and personalized echocardiography data, taking into account the obesity and, possibly, indexing the threshold natriuretic peptide values in patients with BMI ≥30 kg/m2. The issues of indexation of echocardiographic parameters depending on morphometric parameters in obese patients today remain open, predetermining the limitations in diagnosis of heart failure with left ventricular ejection fraction >40%. This requires the search for optimal standardization and the development of a unified methodological approach.

Aim. To optimize the upper gastrointestinal bleeding (UGIB) risk scale in patients Material and methods. The UGIB risk scale was developed based on the with chronic coronary artery disease (CAD) receiving long-term antiplatelet therapy. prospective REGistry of long-term AnTithrombotic TherApy-1 REGATTA-1(ClinicalTrials.gov Identifier: NCT04347200). The registry includes 934 patients with stable CAD (men, 78,6%; median age, 61±10,7 years), 76% of whom were included after elective percutaneous coronary interventions and received dual antiplatelet therapy for 6-12 months. After a UGIB episode, patients were prescribed proton pump inhibitors. The 2015 European Society of Cardiology (ESC) scale was used for assessing the UGIB risk. In addition, we evaluated the ultrasound data on atherosclerotic burden (abdominal aorta and peripheral arteries).

Results. The median follow-up was 2,5 years [1,1-14,7 years]. The incidence of UGIB was 1,9 cases per 100 patient/years. Recurrent UGIB episodes and thrombosis was recorded in 13,7% and 31,4%, respectively. Based on the results of a multivariate logistic regression, a novel scale for assessing the UGIB risk (REGATTA) has been developed. In accordance with the odds ratio, points were assigned for each independent risk factor (RF): age ≥80 years — 3 points, prior gastric erosion, peptic ulcer disease or UGIB — 3 points for each RF, anticoagulation therapy — 4 points, non-steroidal antiinflammatory drug therapy — 2 points. The atherosclerotic burden (peripheral atherosclerosis and/or abdominal aortic aneurysm; 2 points) and heart failure (in most cases after a myocardial infarction; 2 points) were marked as a new independent predictor. The cutoff value (≥4 points) was determined, reflecting the high UGIB risk (sensitivity, 80,4%; specificity, 84,5%). The REGATTA scale was more powerful than the traditional 2015 ESC scale: AUC of 0,88, (95% confidence interval, 0,86-0,9) vs AUC of 0,79, (95% confidence interval, 0,760,82) (p=0,04).

Conclusion. The identified UGIB predictors (atherosclerotic burden and heart failure) and the developed REGATTA scale made it possible to improve the prognosis and prevention of UGIB in patients with stable CAD receiving long-term antiplatelet therapy.

Published: July 2021

The paper discusses the issues of managing uncontrolled hypertension. It is noted that in the International Classification of Diseases, 10th revision (ICD-10), there is no diagnosis “hypertensive crisis”, which complicates the epidemiological estimates. In the new Russian Society of Cardiology guidelines, instead of using the term “uncomplicated hypertensive crisis”, the term “sudden pronounced individually relevant blood pressure (BP) increase” was proposed to describe pronounced BP increase without target organ damage. Since the term “uncomplicated hypertensive crisis” is not recommended for use, but this condition is often diagnosed in practice, it is advisable to replace this term with “sharp BP increase not accompanied by target organ damage” or “sudden pronounced individually relevant BP increase”. At the same time, there is no evidence that in patients with uncomplicated hypertensive crisis, a more rapid BP decrease is more effective over the standard antihypertensive therapy in relation to the risk of complications. The drug Physiotens® lowers BP smoothly and without sudden falls, while having favorable pharmacokinetics. The issues of revising the current approaches to antihypertensive therapy in patients with frequent BP increases, as well as the use of original drugs and generics are considered.

Authors: Das Nipom Sekhar , Gogoi Koustav Kashyap , Chowdhury Avijit
Published: July 2021

Graphene and graphene oxide (GO) have attracted growing attention in the field of resistive switching memory due to their extraordinary structural, physical and electronic characteristics. Moreover, properties such as excellent charge carrier mobility, high mechanical strength, and
outstanding thermal properties make the graphene-based materials suitable for a broad range of other exploitations and many technological applications such as in sensors, energy storage devices, batteries, photocatalysis, electronic devices, supercapacitors etc. The limiting factors such as
low storage density and scaling capabilities in silicon-based memories have led the researchers to explore other alternatives for developing the next generation cost effective data storage devices. The article summarises the recent advances in the field of resistive switching memory and tries
to focus mainly on the use of graphene-based semiconductor heterostructure devices. The article further includes a brief comparison of the memory performances of graphene/GO nanocomposites with various insulating polymers and semiconducting materials.
Polyaniline/oxide-based core-shell like structured composites for reduction in electromagnetic pollution
Authors: Pal Rishi , Goyal Sneh Lata , Gupta Anil Kumar
Published: July 2021

Polyaniline (PANI) based composites with manganese dioxide (MnO2, 30 wt.%) and vanadium pentaoxide (V2O5, 30 wt.%) have been synthesized using the in-situ polymerization synthesis route, whereas both the oxides used as filler materials in the
polyaniline matrix. The amalgamated composites have been analyzed for morphological investigation and shielding the incident electromagnetic (EM) waves in the frequency range 8.2-12.4 GHz (X-band). PANI/MnO2 and PANI/V2O5 composites are synthesized in core-shell
like morphology, whereas PANI act as core while oxide act as the shell. The shielding of EM waves has been investigated in terms of shielding effectiveness (SE). PANI/MnO2 composite exhibits the efficient SE value i.e. ~50 dB as shown in the figure. This higher value of SE is due
to the ferromagnetic character of MnO2 particles which increases the dielectric losses in the specimen. Whereas, PANI/V2O5 composite attain the smaller value of SE i.e. ~9 dB, because V2O5 particles are diamagnetic in nature, thus dielectric
losses decrease. Moreover, SE decreases with an increase in frequency due to a decrease in dielectric losses. PANI/MnO2 composite has an SE value greater than the minimum requirement for industrial application i.e. 30 dB, thus, PANI/MnO2 composite can be used as EM shielding
material, whereas, PANI/V2O5 composite can’t fulfill this requirement.

Published: July 2021

The Boswellia sacra or Olibanum tree has unique herbal properties in the Burseraceae family and has already been considered a versatile material in traditional Arabic medicine. Zinc oxide nanoparticles (ZnO NPs) were synthesized using B. sacra aqueous leaf extract
as a mediator in the present study. As a critical reducing and stabilizing agent for ZnO NPs, B. sacra aqueous extract with reducing polysaccharides and phytochemicals have been used. UV-visible spectroscopy has preliminarily confirmed the formation of ZnO NPs. FTIR, XRD, and SEM analyses
were used to classify the photosynthesized nanoparticles. The functional group present in the nanoparticles was analyzed using FTIR. X-ray diffraction has been used to validate the particles’ crystalline existence. SEM technique determined the nanoparticles’ morphology and crystalline
phase of the nanoparticles. The enhanced photocatalytic activity for methylene blue as model pollutant dye under solar irradiation was 84% in 100 minutes. The antibacterial activity of ZnO NPs was tested using the agar diffusion technique against Staphylococcus aureus, Bacillus subtilis
(gram-positive), and Escherichia coli Pseudomonas aeruginosa (gram-negative) species. ZnO NPs synthesized using B. sacra leaf extract exhibited promising results against Gram-positive and Gram-negative bacterial strains with a maximum inhibition zone of 15 mm and 14 mm, respectively.
In conclusion, the results indicated that the protocol is quick, fast, one-step, eco-friendly, non-toxic, and alternative to physical/chemical traditional methods.
Development and Analysis of Ultrasonic Welding Process Using FEM Approach for Aluminum and Copper
Authors: Patil Pankaj , Periyannan Suresh
Published: July 2021

Ultrasonic welding is a process that uses mechanical vibrations using ultrasonic frequencies. The vibrations are produced by an ultrasonic sonotrode, which is used for joining two thin materials, especially in electronic industries (for applications in battery-making industries). Typically,
ultrasonic welding is based on the parameters (frequency range, input pressure/load of the sonotrode, by varying the coefficient of friction between two metal sheets, the thickness of a sheet) while performing the joining process. In this work, the FEA Model-based study is used for analyzing
the ultrasonic welding using “Von-Misses stress theory concepts”. The effects of various thickness of the sheet, normal force, coefficient of friction (at different welding conditions) are analyzed while performing the welding process. The temperature variation is studied while
using aluminum and copper as thin sheets. This study can be used in the electronic industries for high power ultrasonic welding process, especially using aluminum and copper materials in the form of electrodes, sheets.

Published: July 2021

Abstract This study aimed to assess the effects of environmental temperature and age of broilers on the energy value of corn. A total of 288 Cobb 500 chicks were distributed in a complete randomized design with a split-plot arrangement and six replications of six chicks each. The main plot consisted of three temperatures (cold: 18 ºC; thermoneutral: 25 ºC; and hot: 33 ºC), while the secondary plot consisted of age (initial: 11 to 14 days; growing: 25 to 28 days; and final: 39 to 42 days). The basal diet was based on corn and soybean meal. The test diet was produced by replacing the basal diet for test food: 40% corn + 60% basal diet. The mean values of AMEn observed for broiler chicks under cold, thermoneutral, and hot temperatures were 3322, 3279, and 3233 kcal/kg of natural matter, respectively, and 3215, 3218, and 3400 kcal/ kg of natural matter for the initial, growing, and final phases, respectively. Overall, the metabolizable energy values of corn and the balance and coefficients of metabolizability of nutrients in the test diet increased with the broiler age, but the true metabolizable energies of corn were not affected by environmental temperature. The balance and coefficients of metabolizability of nutrients in the test diet decreased due to heat exposure during the growing and final phases.

Authors: Fioravanti Maria Isabel Andrekowisk , Morgano Marcelo Antônio
Published: July 2021

Resumo A fórmula infantil é a opção de alimento mais recomendada quando a amamentação não é possível. Para o melhor entendimento do comportamento gastrointestinal e da absorção dos nutrientes presentes nas fórmulas infantis, realizam-se estudos que simulam os processos de digestão. Este trabalho teve como objetivo discutir a evolução das fórmulas infantis com foco na avaliação da absorção de Ca, Cu, Fe, K, Mg, Mn, P e Zn, identificando métodos disponíveis para a avaliação de bioacessibilidade e de biodisponibilidade, de forma a melhor entender a absorção desses nutrientes. Para isto, foi realizada uma revisão bibliográfica sobre fórmulas infantis e os métodos in vitro mais utilizados no estudo de minerais, com foco no consumo, na qualidade e nos aspectos tecnológicos. Foi constatada uma tendência mundial no aumento do consumo de fórmulas infantis e verificou-se que estudos de biodisponibilidade e bioacessibilidade de minerais, mesmo que ainda escassos, colaboram para a evolução e o desenvolvimento deste produto, visando a uma aproximação com a composição do leite materno. A pesquisa mostrou que a composição da fórmula infantil vem sendo constantemente aperfeiçoada por revisões das legislações e pela indústria, e que, para a obtenção de uma fórmula infantil com alta capacidade de absorção de nutrientes, devem ser realizados estudos de bioacessibilidade e/ou de biodisponibilidade, pois estes estudos possibilitam uma melhor compreensão da influência dos diferentes ingredientes na absorção dos nutrientes. Os estudos também mostraram que, para uma ingestão mais equilibrada, nas diferentes fases do lactente, são necessárias diferentes composições dos nutrientes nas fórmulas infantis.

Abstract In this work, it was determined the influence of temperature, pH and storage time on the enzymatic activity and stability of an extracellular fructosyltransferase (FTase E.C.2.4.1.9) from Aspergillus oryzae IPT-301 produced by submerged fermentation. The thermodynamic parameters showed a tendency for increasing enzyme denaturation with the rise in temperature. The maximum transfructosylation activity was obtained at the incubation pH 5.5. During storage at 4 °C, the transfructosylation activity decreased, whereas the hydrolytic activity increased, especially in the first nine hours, a time in which the enzyme presented 45.6% of its initial transfructosylation activity. These results contributed to the improvement of the conditions of storage, immobilization and use of the soluble fructosyltransferases (FTase) in fructooligosaccharide (FOS) production.
Transe e desconstrução: a repetição nos corpos de Copacabana mon amour e A idade da terra
Authors: Wahrhaftig Alexandre
Published: July 2021

Resumo Apesar das querelas entre seus diretores e dos quase dez anos que os separam, há muitas proximidades entre os filmes Copacabana mon amour (1970), de Rogério Sganzerla, e A idade da terra (1980), de Glauber Rocha. Dentre os vários elementos que imantam um filme ao outro, destaca-se a performance dos corpos em cenas marcadas por excessivas repetições tanto de gestos quanto de falas. O objetivo desse artigo é, através da análise comparativa, investigar como os dois filmes elaboram a repetição no sentido tanto de apreender o transe místico, elemento central para o filme de Sganzerla, quanto no sentido de desconstruir o próprio andamento do discurso fílmico, algo mais proeminente no filme de Glauber, questões fundamentais na alegoria de ambos.

Resumo O presente artigo tem como objetivo analisar as narrativas sobre a censura às diversões públicas materializadas na atuação de Rogério Nunes, que ocupou a chefia de Divisão de Censura de Diversões Públicas (DCDP) entre os anos de 1971 a 1979, durante a ditadura militar no Brasil. A partir da noção de mentalidade expressa por Vovelle (1991), foi realizada uma pesquisa empírica em acervos de jornais de grande circulação publicados no período, de modo a identificar o tratamento dado ao censor e à prática da censura, e perceber marcas ideológicas que repercutem valores morais vigentes na época.
Coisas que não existem: o papel do som do vento em À sombra do medo
Authors: Carreiro Rodrigo
Published: July 2021

Resumo O objetivo central deste artigo consiste em analisar os usos expressivos do som do vento na produção anglo-jordaniana-qatariana À sombra do medo (2016). Na maioria dos filmes, o vento possui presença discreta, apenas para dar impressão de verossimilhança e reforçar o senso de imersão do espectador na diegese. O filme estudado constitui uma exceção, na qual o sopro do vento incorpora um personagem sobrenatural e conduz o espectador, através do desenho de som, a uma experiência de tensão, desconforto e medo, além de simbolizar a repressão política no país. A análise fílmica será precedida por uma breve revisão histórica do papel do som do vento nos filmes.
Atravessamentos decoloniais da fotografia contemporânea negra sul-africana
Authors: Gonçalves Fernando , Meirinho Daniel
Published: July 2021

Resumo As imagens do artista visual Kgomotso Neto revelam práticas narrativas e estéticas decoloniais africanas representadas a partir de novos marcadores de liberdade e do registro da vida cotidiana nas townships e centros urbanos da África do Sul. O artigo faz uma leitura dos lugares, simbologias e identidades a partir das suas fotografias, enfatizando os modos como a negritude é percebida e construída através de uma lente que dá a ver novas formas de contestação do legado colonial. A partir da análise de dois projetos do artista, o texto argumenta que seu trânsito por distintas referências e linguagens e sua relação íntima com o cotidiano urbano lhe permitem realizar jogos com as representações de corpos e de espaços, convidando-nos a perceber estilos de vida, de liberdade e de moda como lugares de luta e de resistência, com os quais busca apontar e ultrapassar lacunas e opressões coloniais.
Apontamentos para uma filosofia da comunicação em E. Husserl: a questão da intersubjetividade em sua fenomenologia transcendental
Authors: Borges Junior Eli
Published: July 2021

Resumo Em sua vasta obra intelectual, Edmund Husserl toca em arestas importantes que nos fazem pensar — ou mesmo repensar — estratos básicos tanto do próprio conceito como dos modos de operação daquilo que compreendemos por “comunicação”. Como pensar esse termo em sua dimensão mais fundamental, aquela humana? O que nos permite atestar que “nos” comunicamos, que há aí um “eu” e um “outro”? Ou, em outros termos, como se daria uma das condições primeiras do ato comunicativo, a saber, a constituição dessa “intersubjetividade”? A fertilidade teórica com que Husserl trata questões como essas nos incita, neste artigo, a jogar luz sobre alguns de seus escritos como um terreno fecundo para o campo da filosofia da comunicação.
Costurar o tempo: tessituras para um arquivo nagô
Authors: Amaral Diego Granja do
Published: July 2021

Resumo Partindo de um breve exame sobre a questão do arquivo e o mal de arquivo em Derrida ([1995] 2001), este trabalho propõe uma reinterpretação do conceito de arquivo a partir de uma leitura da Arkhé nagô (SODRÉ, 2017) na obra de Rosana Paulino. Como argumento central, defendo a necessidade de se produzir arquivos como espaços de cura e emergência criativa da memória. Com isto em mente, proponho a noção de arquivo nagô em uma discussão que atravessa as manifestações do movimento Black Lives Matter na cidade de Bristol, na Inglaterra, em direção ao trabalho da artista Rosana Paulino, que serve de base para esta proposta. O objetivo é pensar a questão do arquivo no contexto do Brasil contemporâneo e, portanto, desde uma perspectiva não-eurocêntrica.

Abstract The 2010 remake of the horror film A Nightmare on Elm Street focuses on the earthly abuses committed by the now confirmed pedophile Freddy Krueger. The fact that the victims of Krueger’s sexual assaults start getting murdered in their sleep is relevant to the trauma studies, as nightmares are one of the most common symptoms observed in people diagnosed with Post Traumatic Stress Disorder. Therefore, one of the goals of this paper is to analyze the ways in which trauma is portrayed in the movie. Considering that the teenagers can only overcome Krueger — and therefore, their trauma — once they are able to witness the terrible events of their past, this work also aims at observing and discussing the trajectory that allows the protagonists to survive. In order to meet these goals, some central concepts to trauma theory are presented and discussed in relation to their portrayal in the film. The analysis shows that the main character Nancy can only defeat Krueger once she knows everything that has happened in the past and is able to have agency in the story.

Resumo Este artigo tem por objetivo analisar a transição do estado de emprego para o desemprego no mercado de trabalho brasileiro visando compreender que efeito a qualidade do posto de trabalho atual possui sobre a probabilidade de o trabalhador perder sua ocupação no período futuro. A intenção é entender o quanto as características pessoais, socioeconômicas, capital humano e as características de ocupação podem influenciar na probabilidade de os trabalhadores transitarem para o desemprego. São usados dados da Pesquisa Mensal do Emprego dos anos de 2002 a 2016. Os resultados apontam que trabalhadores alocados em categorias mais altas têm menor probabilidade de perder seu posto de trabalho. Ademais, é observado que a escolha da categoria da ocupação tende a ser mais importante para as mulheres, ou seja, os efeitos de uma escolha inadequada hoje afetam negativamente a probabilidade de emprego futura.

Resumo O objetivo deste estudo é apreender tanto as representações sociais de morte como a compreensão desse saber, construído na prática profissional por uma equipe multidisciplinar de cuidados paliativos. Participaram da investigação 20 profissionais de uma equipe multidisciplinar de cuidados paliativos que trabalhavam há pelo menos seis meses na equipe que aceitou participar da pesquisa. Trata-se de um estudo de abordagem qualitativa com delineamento de estudo de casos. A coleta de dados foi realizada por meio de entrevista individual em profundidade. A avaliação dos dados empregou a análise de conteúdo do tipo categorial, com o suporte do software Atlas.ti. Como resultado, afirma-se que os participantes compreendem a morte tanto como parte do processo de vida, quanto como um evento capaz de gerar perdas. Encontraram-se evidências de que a representação social de morte está em transformação nesse grupo, pois as trocas e compartilhamentos de experiências, pautados na filosofia paliativista, fazem com que os profissionais questionem sua própria forma de encarar a morte.
Análise do Discurso de Gênero no Contexto Hospitalar: Perspectivas de Mulheres Internadas nas Enfermarias de Ginecologia e Obstetrícia
Authors: Ruiz Juliana Machado , De Tilio Rafael
Published: July 2021

Resumo O objetivo desta pesquisa foi compreender as formações discursivas (FD) de gênero relativas aos cuidados em saúde de mulheres internadas nas enfermarias de ginecologia/obstetrícia de um hospital. Participaram do estudo treze mulheres e os dados foram analisados a partir da análise do discurso de Michel Pêcheux. As principais FD identificadas destacaram a naturalização da forma como as mulheres devem se relacionar com o sistema de saúde por meio do que é tradicionalmente delegado a esse gênero (mãe e cuidadora), priorizando intervenções voltadas para a saúde reprodutiva, bem como a matriz hegemônica do modelo biomédico na organização desses serviços, distanciando-os dos modelos de integralidade propostos pelas políticas públicas em saúde voltadas para esse público. Considerou-se o campo da saúde enquanto espaço discursivo de (re)produção de estereótipos e desigualdades de gênero, alicerçado em formações ideológicas e imaginárias que são constituintes dos modos como os sujeitos transitam nesse cenário. Propõem-se a compreensão das questões de gênero como conteúdo transversal a todas as áreas e contextos de saúde, partindo da perspectiva de que um melhor entendimento do universo feminino em relação à saúde, alicerçado pelas questões de gênero, pode favorecer a oferta de programas e serviços condizentes com as reais demandas e necessidades dessa população.

ABSTRACT Aim To assess the incidence and factors associated with pressure wounds in patients of a Brazilian clinical and surgical Intensive Care Center (composed of three Intensive Care Units). Method Cohort monitored for clinical and therapeutic variables in an Intensive Care Center. Cox’s Multiple Regression was employed, establishing the number of days until the first pressure injury as a time variable; the omnibus test was also performed. Results 178 patients, 64 (36%) developed at least one pressure wound. The independent variables for the risk of pressure wounds were: Braden <13 (HR: 10.6; 95% CI: 2.5-43.7), history of previous stroke (HR: 2.6; 95% CI: 1.3-5.0), age> 60 years (HR: 2.0; 95% CI: 1.2-3.5), nothing by mouth time (HR: 1.06; 95% CI 1.02 -1.10) and physical therapy days (HR: 0.81; 95% CI: 0.73-0.91). Conclusion Pressure wounds were incident. Braden <13 points, history of previous strokes, being elderly, and time in nothing by mouth were shown to be independent risk factors for pressure wounds. The days of exposure to physical therapy were protective. These findings corroborate recommendations to monitor the frequency of pressure wounds and to establish protective measures based on local indicators.

ABSTRACT Objective To describe the reflection-action process for the development of nurses' competence in prenatal care. Method Action research with 30 nurses from primary health care in a municipality in the south of the country, through workshops held between June and August 2019, analyzed according to Creswell. Results Nurses identify nursing consultation as a differential in prenatal care; point out the ignorance of work processes as an obstacle to the protagonism in prenatal care; and they highlight the registration of activities and the dissemination of the nurse's role with the team and the population as aspects that strengthen and value the profession. Conclusion The workshops enabled reflection to identify and overcome obstacles to the development of a competent practice, by strengthening nurses regarding the work process itself to discuss and implement changes in order to improve and enhance the care provided.

ABSTRACT Objective To investigate the trend of infant mortality from preventable causes in children under one year of age in Rondônia from 2008 to 2018. Method Epidemiological study of time series with data from the Mortality and Live Birth Information Systems, driven by STATA® version 11.0, trend measured by Prais-Winsten linear regression and autocorrelation with Durbin and Watson test. Results The infant mortality rate was 14.57 deaths / 1,000 live births, 9.14 / 1,000 due to preventable causes. Deaths decreased by 2.88% annually (95% CI: - 4.67; -1.06). However, causes that can be reduced by running immunization actions, to women during pregnancy and fetal and non-childbirth growth, have stable rates. Deaths from preventable causes in the late neonatal period were declining (-11.69%; 95% CI -19.56; -3.05). Conclusion Managers need to qualify maternal and child care, considering the performance of the team of professionals in assisting the pregnant-puerperal cycle as well as improving the quality of infant mortality records in the region.
