Authors:   Danylo Halytsky Lviv National Medical University, Ukraine, Myhal I.I.
Published: December 2020

Introduction. The hemodynamic parameters during the Nuss procedure for repair of pectus excavatum are under the influence of surgical procedures and anesthetic components especially regional blocks. The aim of the study: analysing the hemodynamic parameters during the Nuss procedure for repair of pectus excavatum under the combination of general anesthesia with different regional analgesia techniques. Materials and methods. The observative prospective study inclueded 60 adolescents (boys/girls=47/13) undergone the Nuss procedure for repair of pectus excavatum under the combination of general anesthesia with different types of regional blocks. The patients were randomized into three groups (n=20 in each) according to the regional analgesia technique: standart epidural anaesthesia in the dermatome of maximal deformity (SEA), high epidural anaesthesia in Th2-Th3 level (HEA) and bilateral paravertebral anaesthesia (PVA). The deformity severity by Haller index in all patients was 3.9 [3.6–4.1]. The blood pressure (BP) and heart rate (HR) were analyzed at different stages of anesthesia and surgery. Results. SEA resulted to significant derease in BP up to 30% compared to initial level before anesthesia. In the HEA group the decrease in BP was moderate and in PVA group the BP did not decrease at all. The sternal elevation and applying capnothorax increased BP without increasing HR. The bar rotation provided a little hemodynamic change in spite of being the most traumatic moment of such surgery. Under PVA HR was moderately increased but BP was almost unchanged, and the intraoperative infusion volume was the smallest in PVA group. HEA provided more stable hemodynamics in comparison to SEA. At the end of surgery hemodynamic parameters almost the same as initial before surgery. Conclusions. During the Nuss procedure for pectus excavatum repair the blood pressure decreased significantly under the standart epidural anaesthesia in the dermatome of maximal deformity, moderately – under the high epidural anaesthesia in Th2-Th3 level and was stable under the bilateral paravertebral anaesthesia. HR decreased under epidural blocks but not under PVA. The sternal elevation and applying capnothorax increased BP. The initial hemodynamic parameters before surgery did not correlate with the severity of deformity according to the Haller index. The study was conducted in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the institution. Informed consent of parents and children was obtained for the study. The author declares no conflict of interest. Key words: hemodynamics, pectus excavatum, Nuss procedure, epidural anaesthesia, paravertebral anaesthesia.
A Personalistic Approach to Human Rights: Shifting Prevailing Philosophical Assumptions
Authors: García-Escobar Gabriela
Published: December 2020

The aim of this article is to analyze the prevailing philosophical presuppositions in human rights interpretations and how they provide a reductionist and partial vision of the human person and of rationality. This paradigm excludes the experiences and moral concerns of a significant segment of the global population and avoids engaging with the underlying claims behind human rights debates. In response to such a situation, this paper will introduce a personalistic philosophical approach to human rights as an alternative capable of explaining how the concept of ‘person’, as a relational self, can enrich the prevailing rationality in International Human Rights Law. The research suggests that looking at inter-subjective relationships, meaning, and an enlarged concept of ‘human experiences’ can provide a deeper understanding of the human person and it can help to frame human rights discussions in more diversified and inclusive terms.

Published: December 2020

El objetivo de este artículo es revisar la literatura médica y científica (incluida una revisión paraguas) relacionada con el uso de cubrebocas como medida de prevención en la transmisión de enfermedades respiratorias virales para tomar decisiones informadas durante una pandemia. Desde inicios del siglo XX se estableció que el cubrebocas es efectivo para reducir infecciones respiratorias.  El uso entre la población general inició hasta la pandemia de 1918. Desde entonces, las investigaciones se han enfocado principalmente en determinar los mejores materiales para su elaboración, encontrando que la efectividad del cubrebocas aumenta con el número de las capas, siendo ideal tres, de punto cerrado y de diversos materiales. Los meta-análisis demostraron que el uso de cubrebocas disminuye el riesgo de contagio de enfermedades respiratorias virales, incluido COVID-19, comparado a no usarlo. Los cubrebocas evitan el paso de una gran proporción de partículas del virus SARS-CoV-2 protegiendo tanto al portador como al resto de la población al reducir la carga viral a la que se está expuesto, disminuyendo así el riesgo de desarrollar enfermedad grave de COVID-19. Cuando las personas están en espacios públicos es preferible elegir usar cualquier cubrebocas, a no usar ninguna protección naso bucal. Para decidir sobre el uso del cubrebocas es importante evaluar el riesgo-beneficio. Con este análisis concluimos que según la evidencia, los beneficios del uso del cubrebocas superan los riesgos, por lo que recomendamos que el uso de cubrebocas de forma generalizada.

In this paper, we determine an optimal configuration for characteristics of a multilayer perceptron neural network (MPL) in nonlinear regression for predicting crop yield. Monte Carlo simulation approach has been used to train several databases generated by varying the internal structure of 3-MLP from simple to complex for five (5) different algorithms most commonly used. Results showed that the optimal configuration is obtained with the Levenberg Marquard algorithm, 75% of the number of input variables as number of hidden nodes, learning rate 40%, minimum sample size 150, tangent hyperbolic and exponential functions in the hidden and output layers respectively. This configuration has been illustrated with real life data.

Authors: Thompson Emmanuel , Talafha Ahmad Mahmoud
Published: December 2020

This study considers the problem of uncertainty of concurrent variables selection among a potential set of healthcare expenditure predictors. It evaluates two regularization (shrinkage) methods: Least Absolute Shrinkage and Selection Operator (LASSO) and Elastic Net (ENET). To improve the accuracy of identifying important and relevant predictors of healthcare cost, the present study proposes a new methodology in the form of a bootstrapped-regularized regression with percentile rankings. A simulation study under various scenarios was implemented to learn the performance of the proposed methodology. The proposed methodology was applied to healthcare expenditure data for all level income economies: lower-income, lower-middle-income, upper-middle-income, and high-income.

Published: December 2020

Modern trends in the automotive industry are aimed at reducing vehicle weight and increasing its safety. The high ductility of IF-BH steel in combination with increased strength allows the use of thinner rolled products in the car body structure. Achievement of high plastic properties in IF-BH steel is ensured by the low content of nitrogen and carbon (C <40 ppm, N <40 ppm) and controlled carbon content in the solid solution. The majority of sheet surface defects are associated with non-metallic inclusions. The presence of non-metallic inclusions in the finished product violates its homogeneity, deteriorates the surface properties of steel, fatigue strength and plastic characteristics of the metal. As a result of the work performed by the methods of fractional gas and micro-X-ray spectral analysis on a scanning electron microscope, metal samples of three IF-BH steel melts were analyzed, taken along the entire process chain of production. The main types of oxide non-metallic inclusions in the steel were quantitatively determined, as well as the total oxygen and nitrogen content in the metal. It is shown that the main types of oxide non-metallic inclusions in the investigated metal samples are aluminates, silicates and spinel. An increase in nitrogen content in the metal after breakdown of the vacuum on the VD was established, which indicates secondary oxidation of the metal. In metal of the samples in the section between the tundish and the crystallizer, nitrogen content in the metal increases which indicates the secondary metal oxidation. At the same time, the content of inclusions of aluminates in the metal increased and the number of inclusions of aluminum-magnesium spinel decreased. A mathematical model and software have been developed that describe the formation and removal of oxide nonmetallic inclusions. Adequacy of the program was confirmed by good convergence between the calculated and laboratory data on the total content [O] in various types of oxides for the first sample at the ladle-furnace unit and in the slab.

Published: December 2020

The article discusses the prospects of recycling the most massive wastes of aluminum production (namely, used cathode blocks of electrolyzers, gas treatment dust, gas treatment residue, and flotation tailing). It have been indicated the volumes of wasteaccumulation and a special attention has been focused on the need of their disposal with a view to improve the environmental conditions of the territories adjacent to the industrial zones. Specific characteristics of the generated waste have been determined, which indicate the possibility of their secondary use and transfer from waste to by-products.Existing technical solutions relevant to the issue have been reviewed, and the reasons preventing their implementation have been explained. The most promising methods of waste processing to be carried out successfully in the current economic conditions have been identified. Spent cathode blocks can be used at ferrous metallurgy enterprises (in blast furnaces and converters) as a substitute for expensive coke and fluorspar, and finely dispersed waste can be used at cement enterprises. The areas have been determined that in the future will significantly increase the volume of processing and the demand for these wastes of the aluminum industry in technological processes of ferrous metallurgy. The possibilities for cooperation between aluminum refineries and ferrous metallurgy enterprises, as well as other related industries, were emphasized in detail.

Published: December 2020

This article is a preliminary study that explores past events of the Dutch East Indies colonial government, specifically describing criminal cases of hate speech or haatzaai depicted in newspaper news between 1879 and 1942. The Dutch East Indies colonial government controlled freedom of thought, expression, and politics of the native population by using the legal instruments Wetboek van Strafrecht voor Nederlandsch Indie, especially articles 154, 155, 156, and 157. These four articles are known as haatzaai artikelen. This regulation was published and enforced in the Dutch East Indies in 1918. This article uses twenty-eight newspaper news articles published in ten cities on the islands of Java and Sumatra as the primary sources. This is research that uses historical methods by gathering primary
and secondary sources in the National Archives of the Republic of Indonesia (Jakarta), the National Library of the Republic of Indonesia (Jakarta), and the Constitutional Institution voor Taal-, Land- en Volkenkunde (KITLV) (Jakarta). This article concludes that based on the news articles found, haatzaai artikelen, as a repressive legal product, is not only used
by the colonial government to control people’s behavior but also used by fellow members of the community of East Indies to quarrel with each other in many cases of hatred, incitement, and defamation.
EKSISTENSI DAN PEWARISAN BUDAYA TUKU DALAM MASYARAKAT PULAU NDAO (ORANG NDAO) KABUPATEN ROTE NDAO NTT

Published: December 2020

On Ndao Island, Ndao Nuse Subdistrict, Rote Ndao Regency, the people have two prominent skills and have become the livelihoods of the people on the island, namely weaving skills (manènnu) and craftsmen or silversmiths (tuku). The two skills of the above Ndao island community are passed on by parents with informal and non-formal education patterns, but the two cultures experience different developments. Manènnu culture is still developing today among women while tuku culture is almost extinct. To
find out the existence and cause of near extinction of Tuku’s skills, this research was carried out with the formulation of the problem as follows: 1) how the existence of silver or tuku craftsmen on Ndao Island; 2) what is the cause of the almost endangered skill of silversmiths or tuku in Ndao Island; 3) how are the efforts of the people of Ndao Island to pass down the culture of silversmiths or tuku to young generation. This study aims: 1) to find out the existence of silver or tuku craftsmen on Ndao Island; 2) to find out the
cause of the almost endangered skill of silversmiths or tuku in Ndao Island; 3) to know the efforts of the people of Ndao Island to pass down the culture of silversmiths or tuku to their young generation. The method used in this study is a qualitative research method with interview and observation techniques for data collection. From the results of data analysis it can be concluded the following matters: First, there is an effort of cultural
inheritance in society but does not use the right pattern. Second, the lack of interest in the younger generation to learn tuku. Third, the existence of cultural assimilation is the inclusion of a new method of fishing that is using a large trawl boat with a large trawl type so that many young people from Ndao Island who do not want to learn tuku skills and prefer to be subordinates to lampara boats whose income is actually far below the
skills of tuku. Besides that, there are many people who pursue seaweed cultivation, the Fourth. The more difficult the silver raw materials in the community. The fifth pattern of cultural inheritance is not done well and well organized.

Poesia e Filosofia em Richard Rorty
Authors: Alvarenga Souza Bruno Henrique
Published: December 2020

Este artigo tem por objetivo fazer a exposição crítica do pensamento do filósofo americano Richard Rorty no que tange à sua concepção da poesia e sua relação com a filosofia, evidenciando através dos paradigmas filosófico e literário também sua ideia de indivíduo. O corpus textual analisado aqui é basicamente composto por quatro ensaios, nos quais Rorty abordou de forma direta o problema da poesia; são estes: “A contingência da identidade”; “A filosofia como um gênero transitório”; “Pragmatismo e Romantismo”; e “The fire of life”. Tentamos demonstrar e estabelecer a progressão da teorização de Rorty sobre o tema, não se apegando estritamente à linha cronológica dos textos, embora, o comentário ao último ensaio publicado em vida por Rorty, “The fire of life”, devido à natureza testamentária e sintética deste, encerre o trabalho.
Poéticas
Authors: Damasceno Batista Amanda
Published: December 2020

Na seção Poéticas, Marc Davi, capa desta edição, apresenta a fotoperformance “Da sensação de elasticidade quando se marcha sobre cadáveres”. O artista enuncia seu discurso a partir de diversas mídias que apontam para o confronto entre o caráter movediço das linguagens e a natureza arbitrária da substância que as constitui – e convocam os limites do corpo (e seus reguladores sociais) em direção a um tensionamento com o real. Davi parte da incompletude da matéria plástica para provocar um engajamento corporal como veículo último de ameaça possível aos sistemas de domínio que incidem sobre o sujeito. Por sua vez, Renato Contente, na coletânea poética “Solidão Neon”, traz à baila flashes de uma Recife quente e marcada pelo iminente esfumaçamento do objeto amoroso. A epígrafe, que cita Wally Salomão, já dá o tom do que se lerá adiante: “escrever é se vingar da perda/ Embora o material tenha se derretido todo,/ igual queijo fundido”. Em versos carregados de homoerotismo, Contente revisita diferentes passagens de uma relação fadada à solidão, que dura tempo equivalente às chamas da “Camisa amarela”.Jéssica Martins Costa produz uma poética que opera sob o entrelaçar da interioridade com o mundo objectual. Seus três poemas incluídos na presente edição oferecem o vislumbre de uma escrita que tensiona o próprio processo de nomear. Encerrando a seção, com “O surgimento de uma travesti”, Samantha Collins Winchester testemunha as violências e os maravilhamentos que marcam seu processo de percebimento de gênero. Nascida e habitante de um pequeno distrito do interior de Minas,Winchester escreve sobre como o espaço ao seu redor foi definidor de muitas experiências, tanto traumáticas quanto de fortalecimento político.

Published: December 2020

A Teoria da Autodeterminação da psicologia procura explicar a motivação dos indivíduos a partir de fatores intrínsecos que orientam a ação dos sujeitos. No ambiente do ensino, esta teoria contribui para explicar os fatores que influenciam o desempenho do acadêmico. Neste contexto, este trabalho tem por objetivo avaliar os fatores que influenciam o nível de motivação dos discentes de um curso de ensino à distância em gestão pública de uma Instituição de Ensino Superior pública brasileira, à luz da Teoria da Autodeterminação. Foi utilizada a aplicação da análise fatorial por meio da Escala de Motivação Acadêmica, com adaptações ao ensino à distância, em uma amostra de 188 estudantes. Os resultados apontam que os fatores relacionados ao prazer de descobrir coisas novas, de ampliar o próprio conhecimento e a auto superação a vivência de estímulos, são influenciadores da motivação intrínseca dos alunos. Já os fatores relacionados a crença de que a formação universitária aumentará a competência profissional, a provação individual de sucesso nos estudos e a possibilidade de obter um emprego de prestígio no futuro, são os principais elementos que influenciam extrinsecamente os alunos do ensino à distância.

Published: December 2020

O presente artigo é resultado da experiência de oferta de um curso online ministrado no Ambiente Virtual de Aprendizagem Schoology, e voltado para alunos de um dos polos do curso de Licenciatura em Ciências Biológicas a Distância, com o objetivo de analisar dados referentes ao silêncio virtual e evasão em ambientes de educação a distância. Após a realização do curso, foram enviados formulários eletrônicos aos alunos (desistentes, evadidos e concluintes) para a coleta de dados. A análise dos dados coletados permitiu concluir que, mesmo diante do esforço dos mediadores do curso em estabelecer uma comunicação, muitos alunos se mantiveram em silêncio, terminando por evadirem. Os alunos concluintes avaliaram positivamente o ambiente virtual Schoology, reforçando seu uso na educação. Faz-se necessário um maior número de pesquisas sobre o silêncio virtual e seu impacto sobre os índices de evasão/desistência nos cursos a distância.

Os Cursos Online Abertos e Massivos - MOOC - são uma proposta recente de ensino-aprendizagem, originada da teoria conectivista, que propõe um modelo de aprendizagem integrado às novas tecnologias. São cursos que se diferenciam da Educação a Distância tradicional por serem abertos e massivos. No ensino de Ciências, os MOOC possuem difusão ampla, havendo cursos nas diversas áreas específicas como Biologia, Física e Química. Com o objetivo de explorar os potenciais e as limitações relacionados aos cursos MOOC no ensino de Ciências, apresentamos uma revisão bibliográfica na qual elencamos três categorias de análise: avaliação, permanência e recursos para aprendizagem. Para isso, foram analisados artigos do período entre 2010 e 2019, disponibilizados em bancos de dados virtuais, que abordavam a temática MOOC relacionada à alguma área do ensino de Ciências. Os resultados da revisão apontaram que os cursos possuem algumas deficiências relacionadas a duas categorias: avaliação e permanência. Em relação aos recursos empregados nas plataformas, não houve críticas significativas, representando que, neste aspecto, os cursos MOOC têm atendido de forma satisfatória aos estudantes. O estudo concluiu que apesar dos problemas identificados, os cursos MOOC apresentam grande relevância para o ensino de Ciências, tendo já expressado resultados positivos na aprendizagem de conteúdos científicos, no acesso e na divulgação destes conteúdos para diversos públicos.

Published: December 2020

The purpose of this syllabus analysis was to explore the structure of courses focused on social media and geared toward education professionals. Fourteen-course syllabi from institutions located within the United States (U.S.) were analyzed as part of this investigation. The results of the analysis revealed a total of 46 unique topic themes across the different courses. The findings show that the most common course objectives aimed to encourage the application and practice of social media as part of a learning experience and the learners' professional practice. In total, the syllabi listed 67 unique required readings including non-peer-reviewed publications, peer-reviewed journal articles, and textbooks. Last, the analysis of the assignments listed in the syllabi shows that in these social media courses, there was a mix of traditional and non-traditional assessment methods. These non-traditional assessment methods focused on integrating social media as part of the assessment in which learners were required to create a social media account, become familiar with it, and create learning experiences incorporating a specific social media platform.

O desenvolvimento tecnológico e a integração global através da internet transformaram a linguagem e a comunicação, trazendo novos desafios educacionais. Nesse contexto, o presente trabalho se propôs a discutir os principais aspectos que devem ser considerados na utilização do meme no material didático para EaD. Para alcançar os objetivos, propôs-se conceituar e tratar dos principais aspectos da linguagem textual do gênero "meme". Em seguida, buscou-se um maior entendimento sobre os processos subjetivos e afetivos da comunicação no contexto da cibercultura. Por fim, procurou-se expandir a compreensão do material didático como principal elemento de mediação da aprendizagem na Educação a distância. Longe de ser uma conclusão definitiva sobre a temática, o presente estudo revelou-se uma reflexão aberta sobre a utilização da linguagem como mediadora de abordagens pedagógicas mais coerentes com as dinâmicas de linguagem associadas à contemporaneidade.

Published: December 2020

Training is important for the development of skills and knowledge. The purpose of this study was to explore the influence of post- safety training on the supervisors learning process, behaviour towards safety and development of safe work environment in the automotive original equipment manufacturing (OEM) companies. In the present study, a total of 129 supervisor level employees from different Indian automotive OEMs units, who have undergone a minimum of one-day safety training in the past three years, were a part of the survey. The survey was administered with the aid of a pre-validated designed questionnaire (developed in consultation with industry experts) to collect responses from the supervisor’s level employees during the period of January- August 2019. The 63 different manufacturing OEM automotive units from the Delhi- NCR and Pune- Nashik - Kolhapur from Western region agreed to participate in the survey. The results obtained were tested using multiple hierarchical regression analysis in a stepwise method, along with the correlation coefficient analysis. The results indicated that knowledge acquisition, learning process, and employee involvement regarding risks and hazards identification were positively related to the perceived effectiveness of post- safety training by the supervisors. It was further found that the post- safety training has no significant contribution towards the perceived self- behavior change and development of safe work environment. The effectiveness of safety training and development of safe environment along with the change in behavior towards the safety is related to factors such as related education in safety and health, working experience in the field of safety or EHS domain and knowledge of the supervisors gained through their career which play a significant role. A safety culture can be created by the organization by harnessing the safety-related work experience of the supervisors and periodically conducting the skill development program.

Fire is one of the most common production safety accident. The trend of fire can be mastered by analyzing the historical data. This paper explores the features of recent fires in China, predicts fire by two methods, namely, grey theory, and grey Markov theory, and compares the prediction results of the two methods. The results show that: the number of fires in China increased greatly in 2013; Since 2014, the number of fires, as well as the number of deaths, the number of injured, and property loss induced by fires were declining. The maximum relative error of grey prediction was 5.8%, and that of grey Markov prediction was 5%; grey theory is less accurate in fire prediction than grey Markov prediction. According to the causes and features of fires, several preventive measures were put forward. The research results provide insights into the prevention of fires and protection of production safety.
An Efficient Security Model for Password Generation and Time Complexity Analysis for Cracking the Password
Authors: Kumar Bathula Prasanna , Reddy Edara Srinivasa
Published: December 2020

Passwords tend to be one of the most popular approaches to protect operating systems and user’s data also. Most businesses rely on password protection schemes, and secure passwords are incredibly necessary to them. The proposed model typically aims to impose protection by forcing users to obey protocols to build passwords. For user protection, password has become a prevailing method in terms of exposure to scarce tools. The main problem with password is its consistency or power, i.e. how simple (or how difficult) a third person can be "assumed" to enter the tool that you use while claiming to be you. In operating systems, text-based passwords remain the primary form of authentication, following major improvements in attackers' skills in breaking passwords. The proposed Random Character Utilization with Hashing (RCUH) is used for generation of new passwords by considering user parameters. The proposed model introduces a new framework to design a password by considering nearly 10 parameters from the user and also analyze the time for cracking the generated password to provide the system strength. The proposed model aims to generate an efficient security model for password generation by considering several secret parameters from the user. To break a set of consistency passwords, analysis is also performed on time for password cracking. The tests show a close positive correlation between guessing complexity and password consistency. The proposed model is compared with the traditional password generation and cracking models. The proposed model takes much time in cracking the password that improves the systems security.
THE PERSPECTIVE USE OF VARIOUS VALVE SEAL DESIGNS FOR COMPONENTS, FUNCTIONING UNDER ULTRALOW TEMPERATURE AND DYNAMIC FORCE
Authors: Bezrodnyy Ilya I.
Published: December 2020

The need for the use of hydrogen as a proper substitution for kerosene-based aviation fuel is constantly growing. Research has been carried out to develop a fuel system that uses hydrogen since the previous century. The use of this fuel instead of kerosene-based fuel creates numerous technical issues. One of the most important issues is designing a seal for the valves, that would, by their design and the materials used, provide maximum durability and reduce the actuating force for sealing.
