Published: April 2021

Introduction: Early diagnosis of Hepatocellular Carcinoma (HCC) by imaging and biochemical tests would be valuable in controlling morbidity and mortality associated with this most common primary hepatic malignancy which is the third leading cause of global cancer-related deaths. Objective: To determine an association between the level of serum Alpha Fetoprotein (AFP) and the size of the tumor in Hepatocellular Carcinoma (HCC).Materials & Methods: This cross-sectional descriptive study was conducted in Rehman Medical Institute, Peshawar, Pakistan from January 2018 till December 2019. Data were gathered from the medical records of Endoscopy Unit of Rehman Medical Institute. Patients were separated into three groups on the basis of serum AFP levels: Group I had standard levels of AFP (<20 IU/ml), Group II had moderately raised AFP (20-399 IU/ml), and Group III had significantly raised AFP (>400 IU/ml). Patients were also separated into three groups on the basis of tumor; in Group A tumor size was less than 3 cm, in Group B it was between 3 and 5 cm, and in Group C the size was greater than 5 cm. For categorical variables, the Chi-square and Z test for proportions were applied; the Wilcoxon Rank-Sum (Mann-Whitney) test was used to evaluate the variation in the two categories, and the Kruskal-Wallis Rank test was used to evaluate the difference between categories. A p value ≤0.05 was taken as significant. Descriptive statistics were obtained by SPSS 24. Result: A total of 136 patients were evaluated according to AFP levels. The male to female ratio was 2.31:1. The mean presenting age was 59.36 ± 9.85 years while the mean tumor size was 6.93 ± 4.39 cm. Regarding AFP groups, there were 50(36.76%), in Group I, 31(22.79%) in Group II and 38(27.94%) in Group III. As per the Child Pugh classification, Class A, B and C were 69.85%, 16.18% and 0% respectively.Conclusion: Serum alpha fetoprotein was significantly associated with HCC tumor size. Alpha fetoprotein level can be a helpful marker to detect HCC and to differentiate between its initial and late stages. Monitoring AFP levels could be useful to diagnose recurring disease for patients with tumors that produce AFP.Keywords: Serum Alpha Fetoprotein; Hepatocellular Carcinoma; Tumor size.

Black and Blue: Revelations in Harold Mahoney’s X-rayed Anatomical Sections
Authors: Tirak Lita M.
Published: April 2021

Approximately ninety cyanotypes and negatives depicting interior views of the human body – among the most obscure works in the art world – are now in the Rijksmuseum Photography Collection. They have no established provenance, production or creator, and without these factors, interpretations for the last thirty years have resulted in speculations. By examining an original negative and print, aided by research in X-ray history, this study uncovered the missing information.Harold Mahoney, a Chicago-based X-ray technician and an academically trained artist of the early twentieth century, was the original creator of the negatives. With his radiographic process, he managed to capture detailed soft tissue and bone in the same image on film, decades before computerized tomography scans.
Art museums around the world have until now emphasized the universal humanness in the cyanotypes, as the social identity and context were unknown. This research has brought a racial identity to the series through a surviving photograph of a subject that Mahoney chose to supplement his published study. The racial core that appears from beneath the X-rays creates an interpretive framework for an American narrative about this photographic series, resonating with the historical and contemporary need for Black visibility and value. With new social inequities discovered in the cyanotypes that could complicate exhibition, this study also suggests an approach for museums to welcome a Black reclamation of the narrative. This research establishes the provenance and foundational analysis for the series that has fascinated museums and collectors for three decades.

High-luminosity IR galaxies (LIRGs, ULIRGs, and HLIRGs) are important for studies related to star-formation processes in the early Universe, as their luminosity allows to detect them at large distances. High IR indicates active star-formation and often starburst processes, which is typical to HII (starburst, SB) and AGN. An interesting question is whether the starburst triggers AGN or vice versa or there is no direct impact. Considering that very often such objects manifest double and multiple structure, it is also interesting to investigate the interrelationship between the SB, nuclear activity and interactions or merging. We have analyzed the IRAS PSC/FSC Combined Catalogue for search for new bright ULIRGs. By means of the SDSS DR14 data, namely redshifts for those objects having spectroscopy, we have calculated the IR luminosities and have found 114 very high-luminosity IR galaxies; 107 ULIRGs and 7 HLIRGs. Among them, 48 new ULIRGs and 7 new HLIRGs have been discovered. These objects have been studied by SDSS color-color, luminosity-redshift and other diagrams. Further studies will include the content of the sample for activity types and other available data.

Изучены некоторые характеристики модифицированных слоев после катодного насыщения конструкционных сталей азотом и углеродом. Структура слоев исследовалась с помощью сканирующего электронного и оптического микроскопов, элементный состав слоя определялся энергодисперсионным анализом. Микротвердость и шероховатость измерялись стандартными методами. Обнаружено образование оксидных слоев при катодных процессах цементации, азотирования и нитроцементации, сопоставимых с наблюдаемыми при анодной обработке. Отмечен некоторый азотный потенциал катодной оболочки, образующейся в растворах, содержащих хлорид аммония. Показано, что максимальная микротвердость слоя на стали 20 после катодной цементации в растворе глицерина и хлорида аммония достигает 900 HV, что превышает получаемую при анодной цементации. Шероховатость поверхности стали 20, нитроцементованной в растворе нитрата аммония и глицерина, может быть снижена в 1,3 раза последующим анодным полированием в растворе хлорида аммония.

Incorporating batching decisions and operational constraints into the scheduling problem of multisite manufacturing environments
Authors: Ackermann Sergio , Fumero Yanina , Montagna Jorge M.
Published: April 2021

In multisite production environments, the appropriate management of production resources is an activity of fundamental relevance to optimally respond to market demands. In particular, each production facility can operate with different policies according to its objectives, prioritizing the quality and standardization of the product, customer service, or the overall efficiency of the system; goals which must be taken into account when planning the production of the entire complex. At the operational level, in order to achieve an efficient operation of the production system, the integrated problem of batching and scheduling must be solved over all facilities, instead of doing it for each plant separately, as has been usual so far. Then, this paper proposes a mixed-integer linear programming model for the multisite batching and scheduling problems, where different operational policies are considered for multiple batch plants. Through two examples, the impact of policies on the decision-making process is shown.
A computational evaluation of constructive heuristics for the parallel blocking flow shop problem with sequence-dependent setup times
Authors: Ribas Imma , Companys Ramon
Published: April 2021

This paper deals with the problem of scheduling jobs in a parallel flow shop environment without buffers between machines and with sequence-dependent setup times in order to minimize the maximum completion time of jobs. The blocking constraint normally leads to an increase in the maximum completion time of jobs due to the blockage of machines, which can increase even more so when setup times are considerable. Hence, the heuristic to solve this problem must take into account these specificities in order to minimize the timeout of machines. Because the procedures designed to solve the parallel flow shop scheduling problem must deal not only with the sequencing of jobs but also with their allocation to the flow shops, 36 heuristics have been tested in this paper, of which 35 combine sequencing rules with allocation methods while the last one takes a different approach that is more related to the nature of this problem. The computational evaluation of the implemented heuristics showed good performance of the heuristic designed especially for the problem (RCP0) when the setup times are considerable. Furthermore, the evaluation has also allowed us to propose a combined heuristic that leads to good solutions in a short CPU time.
Tragedy, Dignity, and the Dionysian
Authors: Palmer David
Published: April 2021

abstract

Arthur Miller is a moralist, but his moral vision is not as simple as it sometimes is taken to be. Miller does not hold his characters against an objective moral standard; rather, his goal is to encourage his readers to examine the social mores that underlie their own moral judgments and self-narratives. In this way, Miller's project is much like Nietzsche's, as is his vision of tragedy, which is based on the experience of crises in a person's self-narrative or sense of dignity. Like Sean O'Casey and absurdist dramatists, Miller is working within a Nietzschean metaphysics of the tension between our oversimplified Apollonian narratives and the Dionysian complexity of life. Miller's critique of the ways the inadequacies of our cultural myths misguide our lives and our societies continues today in the works of commentators who seek to understand the tribalism and tensions in contemporary American society.

En una era de rápidas transformaciones tecnológicas, desaceleración económica y transición a una “nueva normalidad” postcovid-19, surgen muchas vicisitudes en las diversas actividades económicas, conllevando a la urgente necesidad de otros perfiles técnico profesionales en la fuerza laboral y, a la vez, reformas en los programas de educación superior.
Una de las acciones relevantes será la recualificación expedita de la población para adaptarla a las necesidades cambiantes del mercado laboral. Entre las áreas que se deben promocionar y reforzar en los programas educativos y en el sistema de formación técnico profesional son las competencias en ciencia, tecnologías, ingenierías y matemáticas (STEM, por sus siglas en inglés).
En el análisis de las estadísticas del Ministerio de Educación – Educación Superior 2017, se observa un incremento favorable de matriculados en las carreras STEM; sin embargo, este grupo de carreras solamente representa el 23% del total de la población estudiantil a nivel terciario en El Salvador. Asimismo, solo el 28,5% de los matriculados STEM pertenecen al género femenino, lo que podría limitar la mayor inclusión en la economía formal e igualdad de oportunidades a las jóvenes en el país. Otro hallazgo es que se observan pocas especialidades relacionadas con las tecnologías de la industria 4.0, tales como robótica, arquitectura 3D, analista y científico de datos, inteligencia artificial, internet de las cosas, cloud computing, ciberseguridad, entre otras.
Una de las recomendaciones para iniciar las acciones en materia educativa y de formación del talento humano es, obviamente, integrar una visión compartida entre los diferentes sectores del país (gobierno, academia y sectores productivos) en las reformas educativas pertinentes a ejecutar, entre ellas: 1) Mayor ﬂexibilidad para el diseño curricular, 2) Reducir los tiempos de estudio; diseñar programas de capacitación cortos e intensivos, y 3) Diseñar programas educativos y capacitación para la recualificación de la fuerza laboral (especialmente sin empleo) en nuevas competencias y habilidades en demanda, 4) Promoción de la educación virtual.

El ser humano, como ser social, tiende a agruparse según características compartidas. En ese sentido, se quiso comparar la cosmovisión de la muerte en el cristianismo católico y el islam, y a la vez identificar los ritos mortuorios practicados en estas religiones. La comparación se realizó en el área metropolitana de San Salvador, entre los meses de agosto y noviembre del 2019. Para comprender dicho contexto, la investigación se auxilió de una metodología cualitativa, donde se retomó como instrumento la entrevista. Es a partir de esta técnica que se desarrollaron resultados principales en cuanto a que la muerte es una transición, que los ritos tienen un significado diferente en las dos religiones, que la base de comprensión es la misma, y además que los ritos se practican en torno a una base religiosa y varían de acuerdo con su contexto sociocultural.
Guerra Híbrida: Análise de uma perspectiva

Published: April 2021

Em seu texto publicado em 2015, Andrew Korybko faz uma análise da nova metodologia empregada pelos EUA para interferir na política interna de nações em áreas estratégicas para sua geopolítica. Neste estudo pautado pelo conceito de guerra híbrida, o autor mostra como esse processo de interferência externa conta massivamente com o uso de análise de dados e abordagem indireta para criar o que se chama de armamentização do caos, ou a utilização do caos social como forma de cooptação de uma parcela da sociedade-alvo que trabalhará ativamente contra seus interesses nacionais sem nem perceber: para exemplificar essa dinâmica, faremos uma breve análise do contexto brasileiro com base no conceito proposto pelo autor. Neste texto, sugerimos que o potencial explicativo do conceito como proposto por Korybko para analisar contextos sociopolíticos atuais é grande e, quando combinado aos mais tradicionais temas e teorias de diferentes áreas das ciências sociais, pode criar uma renovação teórica interessante para os desafios enfrentados pelas mesmas neste momento histórico. O artigo está divido em cinco tópicos diferentes, abordando em primeiro lugar o contexto que permite a existência da guerra híbrida e o que a justifica; no segundo momento, analisamos o processo de desenvolvimento dessa técnica; no terceiro, analisamos como ela ocorre pacificamente, enquanto no quarto, analisamos qual o papel da violência; no quinto, fechamos o raciocínio concluindo que o conceito pode enriquecer debates que abordem a corrosão das democracias.Palavras-Chave: Guerra híbrida; Geopolítica; Revoluções coloridas; Guerra de quarta geração; América Latina.
n. 14 - POLÍTICAS DE VALORIZAÇÃO DOCENTE NA REDE PÚBLICA DE ENSINO DE RIO BRANCO/ACRE
Authors: Silva Maria da Conceição De Moura , Hojas Viviani Fernanda
Published: April 2021

Este artigo apresenta resultados de pesquisa de mestrado que teve como objetivo analisar as políticas educacionais de (des)valorização dos professores dos anos iniciais do ensino fundamental introduzidas na rede pública de ensino de Rio Branco/Acre a partir de 2005. A pesquisa foi estruturada em etapas que se interligaram, sendo elas: construção de um suporte teórico mediante a leitura de diversas publicações relacionadas à valorização dos profissionais da educação; e reunião, sistematização e análise de leis e documentos de âmbito federal, estadual e municipal que tratam do assunto. Inicialmente, as atenções se voltaram para as políticas educacionais de caráter mais geral introduzidas na rede pública de ensino do município e, na sequência, para aquelas políticas que apresentam uma relação mais próxima com a questão da valorização dos professores dos anos iniciais do ensino fundamental. A investigação evidenciou que, quando tomadas em seu conjunto, as políticas municipais apresentam caráter contraditório e não representam necessariamente um avanço em direção à valorização docente haja vista que a efetivação de algumas delas está atrelada aos resultados de desempenho das escolas e dos estudantes.

O objetivo desta pesquisa consiste em identificar qual(is) o(s) princípio(s) de Governança corporativa as empresas brasileiras de capital aberto listadas na B3 priorizam em suas ações corporativas. Para tanto, elaborou-se uma métrica composta por 21 questões, alocadas nos quatro princípios da Governança Corporativa: Transparência, Equidade, Prestação de Contas e Responsabilidade Corporativa. A amostra do estudo consistiu em 434 companhias de capital aberto listadas na B3 no ano de 2018. Foi constatado que a Responsabilidade Corporativa é o princípio mais publicizado entre as empresas da amostra e que a Transparência e Equidade obtiveram o mesmo escore empatados com as menores médias gerais da métrica. Busca-se contribuir com a literatura ao focalizar as práticas das companhias listadas na B3 e que se relacionam com os princípios de governança; com as empresas pela possibilidade de atrair investidores ao demonstrarem o resguardo dos princípios da governança; com stakeholders ao tomarem conhecimento da tentativa empresarial de redução da assimetria informacional; e aos órgãos de controle que poderão investigar e implementar medidas nas lacunas das práticas, para que abusos empresarias possam ser impedidos.

O estudo objetivou analisar a eficácia das ferramentas tecnológicas utilizadas pela CGU na detecção de fraudes na aplicação dos recursos federais para combater a pandemia da Covid-19. Como questão problema, buscou-se verificar se as Tecnologias da Informação e Comunicação (TIC,) utilizadas pela Controladoria Geral da União (CGU), eram efetivas para realizar o monitoramento dos recursos públicos federais disponibilizados para combater à Covid-19. A metodologia evidenciou-se como qualitativa, para se descrever dados que foram levantados, por meio de busca em sites do Governo Federal, onde foi realizada análise de conteúdo, com a utilização das metodologias de estudo da fraude e pesquisa da KPMG (2015). Como principais resultados, destacou-se a constatação da efetividade das TIC, s da CGU, pois, conseguiu-se detectar R$ 11,2 bilhões de recursos que foram utilizados irregularmente, onde de acordo com o cálculo do custo da corrupção, esses valores representam uma parcela significativa dos recursos públicos, dessa forma a GCU conseguiu se aproximar desse parâmetro, mostrando-se efetiva com suas TIC, s. A principal contribuição desse estudo, destaca-se no conhecimento das Tecnologias da Informação e Comunicação que são utilizadas pela CGU para combater ilícitos com verbas públicas federais, destacando resultados expressivos dessas ferramentas no acompanhamento da aplicação de recursos públicos no combate a pandemia da covid-19. Para futuras pesquisas sobre o tema sugere-se que sejam levantadas outras variáveis dos envolvidos nas fraudes, como, idade, tempo de trabalho, função que ocupa e outras variáveis, para se promover um estudo mais aprofundado sobre o perfil do fraudador.

A implementação da Lei de Acesso à Informação Pública no Brasil e a cultura do sigilo: análise dos portais do Poder Executivo Federal
Authors: Silveira Pedro Afonso Domingos , Silva Rosane Leal da
Published: April 2021

Este estudo versa sobre a implementação da Lei nº 12.527/2011 (Lei de Acesso à Informação Pública, ou LAI), analisando o cenário nacional de aplicação do direito fundamental representado por esse acesso, após a vigência da lei. Para tanto, utilizou-se o método de abordagem dedutivo, partindo-se dos conceitos de participação e controle social, governo aberto e governo eletrônico, além da importância do assunto para o exercício de novas dimensões da cidadania, intensificadas com o advento das Tecnologias de Informação e Comunicação (TIC). As técnicas de pesquisa bibliográfica e documental são complementadas pelo método de procedimento monográfico, a partir do qual foram eleitos e observados, de maneira sistemática e não participativa, os portais online do Poder Executivo no âmbito federal, englobando ministérios e a Presidência da República, a fim examinar de forma crítica os reflexos da LAI na realidade brasileira de acesso a dados, especialmente em razão da necessidade de superação da cultura do sigilo, ainda existente. A conclusão é de que a Lei nº 12.527/2011, aliada às novas TIC, é um instrumento relevante para a democratização da informação, aproximando agentes públicos e sociedade. No entanto, há inconsistências na implementação da legislação, que ainda não foi capaz de sanar a carência de transparência pública. Verificou-se a necessidade de criação de procedimentos objetivos, transparentes e de fácil assimilação, a exemplo da atualização periódica das informações, bem como da padronização dos portais e maior concentração de dados nos próprios sites das entidades, para facilitar o empoderamento popular e a participação na política nacional.
