The COVID-19 pandemic has led to a health system crisis, deaths and socioeconomic hardship. In order to minimize the consequences of the COVID-19 pandemic in the municipality of Lavras, a partnership was developed between the Lavras City Hall and the Universidade Federal de Lavras (UFLA). The present study aimed to describe the main prevention measures proposed in Lavras and to evaluate the community's perception of the management model towards COVID-19. A public online questionnaire, with 20 multiple-choice questions, about the measures to confront covid was submitted to the Google Forms platform from April 22nd to April 30th, 2020. The data regarding the strategies carried out to deal with COVID-19 was obtained from the published municipal ordinances. During the eight days that the questionnaire was applied, a total of 8,874 respondents from Lavras were obtained. Among these respondents, 31.64% (2,808) were men, 68.15% (6,047) were women, and 0.21% (19) declared "another option". When the participants were asked whether they are respecting the social distance measures, 7,452 (84.1%) of them answered "yes."Also, a total of 57.4% of the participants reported that the social distancing measures compromised their family income. However, despite the impact of this economic compromise on these families, 93.82% of the respondents believe that the measures applied are important. When analyzing the questionnaire responses, it was noticeable that despite residents suffering negative economic consequences, there was great popular approval of preventive measures, such as social distancing and the use of masks. In addition, it was possible to notice the population's trust in the measures recommended by professionals at UFLA and the city hall, highlighting the importance of establishing contact between authorities and the population during decision making.

CULTURA MATERIAL: OPERAÇÕES ANALÍTICAS DE UM ARTEFATO E SUA ABORDAGEM DIDÁTICA COM HISTÓRIA E MATEMÁTICA
Authors: Rannyelly Rodrigues de Oliveira  , Bispo da Silva Ana Paula
Published: February 2023

Este trabalho tem como objetivo organizar a análise de um objeto numa perspectiva pedagógica fundamentada na Cultura Material cuja base está firmada no materialismo histórico da tradição marxista. Segundo Meneses (1983), a Cultura Material é conjunto de normas e práticas sociais, pelas quais o homem se apropria do meio físico. Foram estabelecidas as finalidades especificas: apresentar um percurso metodológico, evidenciando suas etapas de desenvolvimento, que permita analisar um artefato com enfoque na Cultura Material e apresentar uma proposição didática com História e Matemática na perspectiva da Cultura Material. A análise do objeto foi organizada em quatro operações analíticas: descrição, avaliação, análise cultural e interpretação diacrônica do objeto. Foi realizada uma pesquisa bibliográfica e descritiva assumindo como referencial teórico a Cultura Material. A etapa descritiva enfatizou as operações analíticas de uma bandeja, seguida de uma proposição didática no ensino de Matemática. A descrição do escopo matemático da bandeja foi desenvolvida na operação descritiva do artefato. Pode-se concluir que apesar da Cultura Material ter sua gênese nas Ciências Humanas; e ser aplicada, principalmente, nas disciplinas de História, Geografia, Sociologia e Filosofia; não se pode ignorar a existência de conceitos matemáticos em artefatos, cuja função social pode trazer à tona significados culturais. Numa perspectiva historiográfica da Matemática, acredita-se que objetos matemáticos são importantes no cenário histórico-cultural e sua contextualização está relacionada a essa aplicabilidade. Por exemplo, a bandeja ilustra figuras geométricas retratando a Geometria presente no cotidiano construída a partir da mobilização de conhecimento matemático. Por fim, pode-se pensar na Cultura Material em uma abordagem voltada para a Educação Matemática, em que se vislumbra oportunizar a aprendizagem da Matemática envolvendo, além do estudo dos conceitos matemáticos presentes no objeto, o conhecimento histórico que está incorporado no mesmo.

Published: February 2023

O objetivo deste artigo é analisar os anais dos principais eventos referentes às pesquisas brasileiras, catálogo de teses e dissertações brasileiras, periódicos nacionais e dois periódicos internacionais difundidos no Brasil, os quais versam sobre a inclusão de estudantes com deficiência visual nos processos de ensino e de aprendizagem do conceito de função. Para isto, foi realizada uma pesquisa de abordagem qualitativa, de cunho bibliográfico, a partir, de uma revisão da literatura, foi utilizada, para demarcação temporal a promulgação da Convenção sobre os Direitos das Pessoas com Deficiência. Assim, recolhemos trabalhos publicados no período compreendido entre 2006 e 2020, nas principais bases de dados que disseminam investigações sobre o ensino de Matemática. Para isto, foram utilizados, inicialmente, os seguintes descritores: inclusão, Educação Inclusiva, conceito de função, deficiência visual, cego e baixa visão. Os estudos apontaram para uma necessidade de substituir símbolos matemáticos presentes na escrita Braille, como forma de simplificar a leitura e o entendimento das informações escritas. Além disso, a necessidade de explicar aos estudantes cegos que a leitura dos gráficos das funções, não pode ser realizada por linha, como comumente ocorre na leitura de textos impressos em Braille. Ademais, os estudos apresentaram um apelo para a utilização de materiais e metodologias que possam vir a permitir a superação do visocentrismo nos processos de ensino e de aprendizagem da Matemática.

Authors: Nunes Machado Junior Ricardo , Araujo Guedes Gabriel
Published: February 2023

Neste artigo, adotamos o estilo “survey”, no qual copilamos e concatenamos os principais resultados e aplicações sobre polinômios de torre. Esse conceito da combinatória nos permite associar problemas enumerativos à distribuição de torres não atacantes em um tabuleiro. As motivações para estudar essa teoria advém da possibilidade de agregar diversos problemas combinatórios com restrições numa única técnica, além do caráter visual que pode ser empregado ao criar uma imagem do tabuleiro e sua fácil implementação computacional. Na Seção 4, exibimos a robustez do método deduzindo resultados para permutações caóticas, com elementos repetidos ou com pontos fixos, permutações k-posicionadas e permutações discordantes. O texto é repleto de bons exemplos, destacamos a resolução do problema das coincidências e o problema dos encontros. Disponibilizamos um complemento on-line, feito em PreTeXt, contendo os códigos das implementações em SageMath e versões interativas, que podem ser utilizadospor discentes e docentes que queiram engrandecer seus trabalhos.

Published: March 2023

200 hemispheres of the brain of people who died from diseases not related to brain pathology were studied. Morphometric method was used and statistical analysis was completed. It was found out that the width of the right and left hemispheres of the brain in both men and women of brachycranial skull type is slightly greater than of mesocranial and dolichocranial ones. Men and women with dolichocranial skull type have the width of the left hemisphere greater than the right one. Men have the width of the left and right hemispheres greater than women. The limits of individual variability of brain hemispheres’ and occipital lobes’ width have been determined taking into account the type of skull and sex. The largest indicators of the cerebral hemispheres’ width are the next: men of the brachycranial skull type have the right hemisphere’s width of the 70.6•10^-3 m, left one of the 71.4•10^3 m width; the women of the brachycranial skull type have the right hemispheres’ width of the 63.4•10^-3 m and the left one of the 63.8•10^3 m, the women of the mesocranial skull type have the left hemisphere’s width of 63.7•10^3 m. The smallest indicators of the cerebral hemispheres’ width are: men of the dolichocranial skull type have the width of the right hemisphere 44•10^3 m, of the left one of the dolichocranial skull type and of the brachycranial skull type have the width 43.8•10^3 m; women of the dolichocranial skull type have the width of the right hemisphere 38.5•10^3 m, left one of 42.5•10^-3. The largest indicators of the occipital lobes’ width are: men of the brachycranial skull type have the width of the right hemisphere 56•10^3 m, men of the mesocranial skull type have the width of the left hemisphere 65•10^3 m; women of the dolichocranial skull type have the right hemispheres’ width 58•10^-3 m, of mesocranial skull type have the left one is of 63•10^-3 m and of dolichocranial it is of 62.5•10^3 m. The smallest indicators of the occipital lobes’ width are: men of the dolichocranial skull type have the width of the right lobe 41•10^3 m, of mesocranial and brachycranial types it is 42•10^3 m, the width of the left lobe in men with dolichocranial skull type of 38•10^3 m; women of the mesocranial skull type have the right lobe’s width of 36•10^3 m, the left one of dolichocranial skull type it is of 34•10^-3 m.

KNOWLEDGE ABOUT GENETICS AND TRUST IN GENETIC TESTING IN A MID-SIZE CITY IN ARGENTINA
Authors: Mendoza M. , Mazza B. , Cabana G.S. , Smith L. , Di Fabio Rocca F. , Delfino H. , Martínez C.
Published: March 2023

Public attitudes about genetics appear to depend on the local context. We analyzed survey responses obtained in 2015 from 293 residents of Luján, a city in the province of Buenos Aires, Argentina, who self-assessed their knowledge about genetics and their trust in genetic tests. The survey integrated a larger research project for which consenting adult participants shared demographic and genealogical information and provided saliva samples for genetic ancestry analyses. Participants reported little knowledge but high trust in genetic testing when questioned about knowledge and trust. Well-known media stories of DNA-based forensic genetic investigations to identify the victims of state repression during the military dictatorship may have contributed to the high self-assessment of their genetic knowledge expressed by some participants, regardless of educational attainment. Our analysis provides information that could be used as a baseline to begin unraveling the current level of public trust in genetics in a region of the Global South where genetic testing has become widespread, but people’s knowledge of and trust in genetics remain poorly studied.

Key words: genetic tests, knowledge, public attitudes, trust
“Brujas” euskaldunes alavesas en el proceso inquisitorial de Logroño (1609-1614)
Authors: Fernández de Pinedo Kike , Otsoa de Alda Xabi
Published: February 2023

Entre 1609 y 1614, el proceso inquisitorial llevado a cabo en Logroño tiene como parte de sus protagonistas a personas acusadas de brujería originarias de la Llanada Oriental y de la Montaña alavesas. Las declaraciones que se conservan, realizadas todas en 1611, bien acusatorias o las posteriores revocatorias, necesitan de intérprete de “bascongado” para que las autoridades inquisitoriales pudieran entenderlas. Estos hechos, sumados a otros similares, refuerzan la idea de monolingüismo euskérico en gran parte de la geografía alavesa en los inicios del siglo XVII. Muestran también que el impacto de la Inquisición en Álava ha sido mayor que el considerado hasta ahora.
Pants design and pattern generation based on body images

Published: March 2023

The personalized pattern generation method based on 2D body-measuring technology has considerable application
potential in clothing e-commerce, remote clothing customization, clothing production, and other aspects. By inputting the
front and side body images, this study proposed a new method of generating personalized patterns automatically. The
silhouettes could be extracted from the body images to estimate body sizes and design style. The basic rules between
the patterns and the body sizes were analysed, and the rules of the general pattern generation were established through
a knowledge-based combination of the basic pattern and the style parameters. The sizes extracted from images were
compared with the manually measured values, and the errors of these sizes were analysed. Sample pants were made
and tried on with the automatic pattern generation system, and the experiments showed that the sample pants have a
good fit at some key landmarks. As a result, this system can automatically generate personalized patterns and style
designs based on 2D human body images, to improve garment fit and accelerate clothing customization.

The Information and Communications Technology sector may be organized into individual technologies or solutions.
Theoretical literature review argues digitalization technologies make up enterprise architecture and shape business
processes or business models. It also shows contemporary business models market solutions for a given value or
impact, rather than sell individual technologies per se. Empirical data confirms enterprise architecture is the market for
system integration. Market data shows the market leader is Software AG. The goal of this article is to build a theory with
an emerging case example of more technologically and business model sophisticated solutions than the theoretical and
market benchmark. The methodology is a dual case study on important market players, Siemens and PTC. The
standalone cases allow for similar solutions which cannot be otherwise tested or validated. Reference is also paid to
other market players within the article. The empirical data analysis is compared to acceptable benchmarks, theoretical
literature review and the enterprise architecture market leader Software AG. Findings show emerging technologies add
capability maturity levels to accepted system integration. Network business models with a quantifiable and provable
customer value proposition: bespoke or personalized products, reasonable cost per item, and zero inventory achieve
the vision of mass customization. The business models are enabled by the highest level of digitalization capability
maturity, not considered in the status quo literature review and at the leading enterprise architect. They place the textile
industry at the forefront of technological innovation and extended reality-based marketing.
Sobre la definición y cálculo de la Energía de Falla de Apilamiento
Authors: Bravo Constanza , Monsalve Alberto
Published: February 2023

Los aceros austeníticos de alto contenido en manganeso (Mn > 20%) de estructura FCC, pertenecen a la nueva generación de aceros avanzados de alta resistencia, esto por su buen comportamiento mecánico global. Las mejores propiedades de estos materiales se deben a la competencia entre los distintos mecanismos de deformación que pueden manifestarse, estando estos relacionados con la Energía de Falla de Apilamiento (EFA), que define la prevalencia de un mecanismo por sobre otro, siendo estos el deslizamiento de dislocaciones, el maclado mecánico y la transformación de austenita-γ a martensita-ε. Este artículo explica el concepto de la Energía de Falla de Apilamiento dentro de materiales FCC, los métodos de obtención y los mecanismos de deformación que son regidos por esta, para finalizar con el planteo del modelo de Olson y Cohen y su aplicación en un acero específico de composición Fe-22%Mn-0,6%C en un rango de temperatura entre 50 a 600 [K]. Se demuestra que la EFA es proporcional a la temperatura y que se relaciona principalmente con la interacción de los elementos de aleación.

Authors: Cahyadi Rino Tam
Published: March 2023

The LQ45 index is a group of 45 companies that have the largest level of liquidity and market share on the Indonesia Stock Exchange. The facts show that there are still inconsistencies in the distribution of dividends by several LQ45 indexed companies. Researchers investigated the topic of funding surplus factor which means that the company has more cash balances so that it is suspected could influence on the dividends. The novelty of this research is the added intervening variable namely investment opportunity set to prove the indirect relationship between surplus funding and dividends. This study uses intervening variable regression with path analysis testing: Sobel Test in testing the intervening variable. The results showed that the funding surplus proved to have no direct nor indirect effect on dividends. In addition, the researcher also finds that there is no difference in dividends distributed between companies with surplus financial condition and companies with funding deficit.

Red bone marrow samples investigation in deceased COVID-19 patients enabled to identify the phenomena of secondary hemophagocytosis. Analysis of the data showed that phagocytic reactions during infection of patients with SARS-CoV-2 are manifested both in relation to erythrocytes and leukocytes. The data obtained make it possible to expand the strategy of therapeutic measures, taking into account the new data on the mechanisms of the pathogenesis of COVID-19 in severe viral infection based on morphological findings and additional information on the involvement of young erythrocytes and lymphocytes in the structure of the red bone marrow in the cascade of pathological reactions. The results obtained confirm a wide range of aggressive damaging effects of SARS-CoV-2 in the development of multiple organ failure against the background of COVID-19 and the involvement of the red bone marrow in the pathological process. The authors supplemented information about the mechanisms of hypoxia in COVID-19, which is not only a consequence of damage to the respiratory epithelium, but also the result of damage to erythrocyte differons both at the level of red bone marrow and in peripheral blood. This fact must be taken into account in the development of a treatment strategy and in the creation of new drugs for the treatment of infected patients with various strains of SARS-CoV-2.

Este trabalho é a reunião de diferentes escritos autoetnográficos como resultados de imersões memorialísticas nos sentidos elaborados sobre o campo/roça a partir das histórias de vida e das culturas dos(as) autores(as) circunscritos(as) em específicos contextos e ruralidades. O que se pretende com este artigo é, entre outras coisas, demonstrar a capacidade dos(as) autores(as) de, por si mesmos(as), pesquisar, compreender, interpretar, descrever e publicizar o conhecimento construído sobre suas existencialidades, identidades e culturas do campo/roça, que são os obje-tos de pesquisa das autoetnografias e, assim, poder romper com o ‘objetivismo-cartesiano’. O texto tem como característica a presença de diferentes vozes, portanto um anfiteatro polifônico de onde é possível ouvir a difusão eloquente e engajada das vozes emitidas no híbrido lugar do pesquisador(a)-pesquisado(a), do objeto-sujeito, da ação-e-do-locus. Nesse sentido, as autoetno-grafias, dispostas em partes, são singulares e distintivas nas vozes que narram ‘de si pró-prios(as)’, no entanto, são avizinhadas, pois, todas nascem das memórias e das as experiências vividas de cada autor e autora e seus vínculos com o campo/roça.
Abstract: This work is the gathering of different autoethnographic writings as results of memorialistic immersions in the meanings elaborated on the countryside from the life stories and cultures of the authors circumscribed in specific contexts and ruralities. The aim of this article is, among other things, to demonstrate the authors' ability to research, understand, interpret, describe and publicize the knowledge built on their existentialities by themselves, rural/rural identities and cultures that are the research objects of autoethnographies and, thus, being able to break with the ‘Cartesian-objectivism’. The text is characterized by the presence of different voices, therefore a polyphonic amphitheater from which it is possible to hear the eloquent and enga-ged diffusion of voices emitted in the hybrid place of the researcher-researched, of the object-subject, of the action-and-do-locus. In this sense, the autoethnographies, arranged in parts, are unique and distinctive in the voices that narrate themselves, however, they are close, as they are all born from the memories and experiences of each author and author and their links with the field/cropland.

This work aimed to apply a didactic sequence (DS) for environmental awareness of basic-education (BE) students regarding bromeliads and their importance for maintaining biodiversity. The activities were developed in four primary and secondary years (primary 3rd and 4th, and also 4th and 9th years of the secondary), during a school semester, through multidisciplinary projects, using 10 stages of a DS as a base plan for all classes (with proper adaptations to each class). The stages of DS were planned using project approaches, three-moment approach, inverted classroom and field activities. During the activities, the students' commitment to the issues raised was noticed, as well as an awareness of the importance of bromeliads and their relationship with the environment. In general, throughout the execution of the project, the students were motivated by the themes presented, and at the end of the activity, they were better able to respond clearly and critically about the environmental issues raised in the classroom, both with the theme "importance of bromeliads” as with “environmental education and conservation”.

Desa Bawukan Kecamatan Kemalang Klaten, mayoritas masyarakatnya mempunyai ternak sebagai sumber tambahan untuk keluarga. Ternak yang dipelihara antara lain sapi dan kambing. Keuntungan dari memelihara ternak, berdampak pada ekonomi warga dengan penghasilan ladang utamanya dan ternak sebagai penghasilan tambahan. Limbah ternak (kotoran ternak) mampu mengurangi biaya produksi pertanian karena menghemat pembelian pupuk. Pakan merupakan salah satu faktor yang sangat penting untuk peningkatan produktivitas ternak. Pakan dengan kualitas dan kuantitas yang cukup sangat dibutuhkan untuk mendukung pertumbuhan dan produksi ternak. Pakan memegang peranan yang sangat penting di dalam keberhasilan suatu usaha peternakan. Total produksi dalam usaha peternakan sekitar 80% nya keluar untuk pakan saja. Di desa Bawukan sumber pakan ternak dari alam melimpah pada musim tertentu saja. Ketika musim kemarau dan air susah di dapat para peternak kesusahan untuk mencari sumber pakan ternak sehinga warga untuk mencari rumput harus pergi keluar daerah sedangkan untuk mencari membutuhkan waktu lama untuk perjalanan. Pada musim kemarau rumput yang biasanya untuk pakan ternak mengering karena kekurangan air. Untuk itulah melalui PKM ini sudah dilakukan pelatihan pembuatan pakan ternak fermentasi dengan metode Silase, untuk memenuhi kebutuhan pakan ternak dimusim kemarau. Juga dilakukan pelatihan menentukan Harga Pokok Penjualan hewan ternak untuk mengetahui keuntungan atau kerugian.

Vanadium oxides (VOx) are representative materials with a high temperature coefficient of resistance (TCR); however, VOx films can have complex phase structures that are dependent on their fabrication method. While past research has focused on the TCR behavior of VOx thin films, this study investigates the TCR of VOx thin films annealed at different temperatures as well as focuses on the relation between the VOx phase, surface morphology, sheet resistance, and TCR. VOx thin films were deposited via radio-frequency magnetron sputtering and annealed at 150 °C–500 °C in 20% O2. Alongside morphological changes, the deposited VOx thin films exhibited phase changes from V2O5 to VO2 with increasing annealing temperature. The VOx thin films annealed at 300 °C and 330 °C showed the lowest and highest average TCR of 1.25%/°C and 3.34%/°C, respectively. Furthermore, a bolometer fabricated using the higher-TCR film showed more than 5-fold infrared responsivity under the same infrared intensity.

The Positive End Expiratory Pressure (PEEP) parameter is a parameter that must be considered in the process of determining the patient's condition, a safe threshold, and must be in accordance with the settings. However, often the PEEP value on the ventilator does not match the settings so that the measuring instrument capable of detecting PEEP on the ventilator is the Flow Analyzer. The purpose of this study was to design a Flow Analyzer using the MPX2010 sensor to analyze the stability of the PEEP parameters on the ventilator. This study used PEEP settings of 0, 5, 8, 11, 14, 17, 20, 23, 26, and 29 cmH2O. Data were collected using a ventilator with VCV (Volume Control Ventilation) and PCV (Pressure Control Ventilation) modes. The tool used for reference from standard measurements uses the Standard Flow Analyzer tool. The results of this study indicate that the measurement accuracy of PEEP parameters with the Flow Analyzer module at each PEEP setting has the smallest error of ±0% at 0 cmH2O setting so that it also has the smallest value of 0 by standard. deviation and uncertainty (UA) value 0 at each setting. The Flow Analyzer measurement module has the largest error in the 5 cmH2O setting, which is ±13.2% with the largest correction value of 0.77. From the data obtained, it can be said that the monitoring of the PEEP parameter is quite stable even though the value is still out of tolerance. Monitoring of PEEP stability parameters can be implemented during the ventilator calibration process which needs to be carried out to analyze damage and reduce the time of damage to the ventilator.

The coronavirus disease 2019 (COVID-19) pandemic has brought a major impact to health
systems and societies worldwide. However, knowledge about the effect of COVID-19 infection
during pregnancy and the perinatal outcome is still limited and no specific recommendations
available yet on the management of this condition. This was a literature review study on the
characteristics of pregnant women, types of delivery, and neonatal outcomes associated with
COVID-19. The database used as the literature source were PubMed, AJOG, NCBI, RCOG,
and Google Scholar and the search was performed on the articles published from July 2021 to
August 2021 that meet the inclusion criteria. Eleven articles were included in this study and
were extracted and analyzed using statistic summary. The majority of the term pregnant women
in labor with COVID-19 were 21-35 years old (86.4%) and 55.5% were multiparous, with the
majority of them delivered their baby through caesarean section (74.3%). The perinatal
outcomes demonstrated that a small percentage of newborns experienced low birth weight
(10.9%) and asphyxia (3.3%). Further studies are needed regarding vertical transmission from
women in labor with COVID-19 to their baby.

The ability to solve problems is an important thing to teach students. This is because, in real life, every individual faces various problems that need to be faced and resolved. This research was conducted with the aim of increasing students' ability to solve problems in the Global Perspective Course with the Topic: The Influence of Science and Technology in Human Life. The research method used is Classroom Action Research which includes: planning, implementing action, observation, and reflection. Before the action is taken, the initial data on student abilities are recorded by giving an initial test (pretest). This study's results indicate an increase in students' ability to solve problems in the Global Perspective Course. It can be seen from the difference in the results of problem-solving abilities in the pre-cycle, cycle one, and cycle two which continued to increase where in the second cycle 80%, namely 92.1% (35 students) were able to solve problems well and scored above the completeness standard. There is an increase in the activity of lecturers and students from cycle I to cycle II, which is above 80%.

Increase in the size of gingiva referred to as “gingival enlargement,” usually overlls the interproximal spaces, ballooning out over the teeth and sometimes even protruding into the oral cavity. It may occur as localized enlargement in relation to a single tooth, a group of teeth, or may be generalized involving the entire dentition. Sometimes, it may appear as diffuse enlargement of gingiva without any specic etiologic factor. It is then considered as idiopathic enlargement. Patient with gingival hyperplasia should be examined to exclude other reasons to determine the idiopathic gingival bromatosis or not. Treatment is not required in all cases of idiopathic gingival hyperplasia. Surgical excision is indicated if mechanical problems exist. In this case report, an idiopathic gingival enlargement was successfully treated using gingivectomy by ledge and wedge procedure. This describes an unusual case of non-syndromic generalized idiopathic gingival bromatosis in a 19-year-old female. Surgical treatment in the form of ledge and wedge procedure with internal bevel gingivectomy was performed .The surgical technique performed yielded functionally as well as esthetically satisfying results and at the same time, it maintains the integrity of periodontium
