Ava y Ova como Recursos Ubicuos
Authors: Pérez Lancheros María Luz
Published: October 2022

Las nuevas tecnologías dan un vuelco a la humanidad constantemente. Los productos se transforman de bienes y posesiones a servicios inmateriales, tal como la educación, el desarrollo de software, la asesoría financiera, etc., que poco a poco han crecido hasta convertirse en grandes generadores de capital. Se hace evidente, entonces, que el conocimiento en plataformas tecnológicas e innovación es de vital importancia en un mundo tan ajetreado y cambiante como el que se vive actualmente. La enseñanza tiene un papel fundamental en dichos procesos. Las personas ya no deben aprender como en antaño, cuando el cambio era paulatino, sino que deben ser capaces de aplicar, con decisiones rápidas y eficaces, el conocimiento adquirido a situaciones inesperadas o ajenas, y así abrirse paso por el camino hacia el futuro.

Authors: Aquino Luseni , Alencar Joana , Stuker Paola
Published: October 2022

Esta publicação é um seguimento da pesquisa O Poder Judiciário no Enfrentamento à Violência Doméstica e Familiar contra as Mulheres, desenvolvida com a colaboração do Conselho Nacional de Justiça (CNJ), entre 2018 e 2019. A atuação do Ipea foi concretizada por meio de parceria entre a Diretoria de Estudos e Políticas do Estado, das Instituições e da Democracia (Diest), que em seus pouco mais de dez anos vem desenvolvendo importantes trabalhos junto ao Poder Judiciário, e a Diretoria de Estudos e Políticas Sociais (Disoc), que ao longo de sua trajetória realiza diversos estudos de gênero. A ideia central dos textos aqui reunidos é retratar e analisar o trabalho desenvolvido pelo conjunto de profissionais envolvidos na aplicação da Lei Maria da Penha (Lei n° 11.340/2006). As reflexões baseiam-se nas práticas que formam o trabalho de magistrados(as), promotores(as), defensores(as) públicos(as), servidores(as) de cartório e integrantes de equipes multiprofissionais, e enfocam a maneira como esses atores compreendem a legislação e justificam seu papel no tratamento dos casos e na relação com as mulheres em situação de violência. O ponto de vista delas é objeto de um dos capítulos, que discute suas percepções sobre o atendimento recebido e suas chances de acesso efetivo à justiça.

A Importância de olhar para os atores envolvidos na aplicação da Lei Maria da Penha aos casos de violência doméstica
Authors: Aquino Luseni , Alencar Joana , Stuker Paola
Published: October 2022

Introduz a importância de olhar todos os envolvidos na aplicação da Lei Maria da Penha aos casos de violência doméstica. O objetivo foi trazer a público análises críticas não apenas das práticas cotidianas dos profissionais envolvidos, mas também das ausências que dão forma ao fazer jurisdicional nesse âmbito. Ao problematizar esse cenário a partir das situações de violência vividas pelas mulheres e levadas até os órgãos de justiça, no ano em que a Lei Maria da Penha completa quinze anos, o que se pretende é contribuir para as reflexões sobre os aprimoramentos necessários para a efetivação do acesso à justiça para as mulheres que buscam, também por meio da prestação jurisdicional, a defesa de seus direitos e uma resposta da sociedade para as violências a que são submetidas.

Interdisciplinary Perspectives to Sustain Effective Post-COVID-19 Classrooms
Authors: Omodan Bunmi Isaiah
Published: October 2022

Since the outbreak of COVID-19, teaching and learning have experienced various challenges and shifts from normal classroom dimensions to what several scholars regard as the "new normal." This situation disrupted teaching and learning systems, with various institutions trying to find alternative ways to ensure effective curriculum implementation. In the event that COVID-19 seems to be a thing of the past, there is a need to understand how best education actors could navigate the new shift. Therefore, researchers need to continue to work on improving educators' understanding of how best to teach and learn and how students and educational institutions respond to the shift in the post-pandemic classrooms. Based on this, a special issue was initiated to galvanize findings, views, approaches, and strategies to enhance sustainable post-COVID-19 pedagogical needs. Therefore, this special issue plays an essential role in helping students, scholars, educators, policymakers and educational agencies understand the present pedagogical shift and prepare for the future.

Keywords: Post COVID-19 Classrooms, teaching and learning, new normal, pedagogical needs.
Entropy of Generating Series for Nonlinear Input-Output Systems and Their Interconnections
Authors:   Old Dominion University, USA, Gray W. Steven
Published: October 2022

This paper has two main objectives. The first is to introduce a notion of entropy that is well suited for the analysis of nonlinear input-output systems that have a Chen-Fliess series representation. The latter is defined in terms of its generating series over a noncommutative alphabet. The idea is to assign an entropy to a generating series as an element of a graded vector space. The second objective is to describe the entropy of generating series originating from interconnected systems of Chen-Fliess series that arise in the context of control theory. It is shown that one set of interconnections can never increase entropy as defined here, while a second set has the potential to do so. The paper concludes with a brief introduction to an entropy ultrametric space and some open questions.
Desenho e análise de uma fonte de luz LED para aplicações em Fototerapia
Authors: Pontes Jhonatan De Abreu Soares , Gómez Sergio Leonardo , Turchiello Rozane De Fátima , Agostini Eloi
Published: October 2022

A Fototerapia é atualmente a terapia mais utilizada para o tratamento da hiperbilirrubinemia neonatal. Embora simples e eficaz, esta terapia não invasiva requer cautela e acompanhamento cuidadoso para garantir a segurança do tratamento. A eficácia da Fototerapia depende da fonte de luz, da dose de irradiância e da área superfícial exposta do corpo. Considerando que o espectro de absorção da bilirrubina in vivo encontra-se na região de 450 a 490 nm, luz com comprimento de onda na região do azul é considerada a mais eficaz para o tratamento da hiperbilirrubinemia neonatal. Nesse estudo, apresentamos o desenvolvimento de uma matriz de Light Emitting Diode (LED) com emissão na região do azul para ser utilizada no tratamento da hiperbilirrubinemia neonatal através do uso da Fototerapia. A fonte de alimentação para essa matriz de LED é baseada no retificador SEPIC para garantir operação com elevado fator de potência e mínima ondulação de alta frequência na corrente de entrada.
Coação da Teoria da Aprendizagem Significativa e do ensino experimental como metodologia para o ensino de Física na graduação
Authors: Colaço Moisés , Aiolfi Eron Brayan
Published: October 2022

Dentre as disciplinas de maiores aplicações experimentais se encontra a Física, e por esse motivo ela se torna um atrativo ao ingresso de alunos no universo das ciências exatas e tecnológicas. Entretanto, a prática experimental é muitas vezes suprimida no meio acadêmico devido às metodologias expositivas adotadas por muitos professores, o que subutiliza as estruturas laboratoriais das universidades e pode ocasionar uma grande improdutividade no aprendizado da disciplina. Este trabalho visa a concepção de um arquétipo metodológico objetivado na atenuação da mecanização do ensino de Física por intermédio de metodologias ativas na busca do aprendizado sólido por meio da imersão entre teoria e experimentação orientada pela teoria da aprendizagem significativa, a qual é fundamentada no conceito de que a aprendizagem ocorre através da associação hierárquica cognitiva das informações. Neste documento é apresentado um exemplo da metodologia pedagógica voltado à disciplina de Física III ou Eletromagnetismo, no qual em conjunto com a aprendizagem teórica ocorre o conhecimento pela experimentação por intermédio da construção de um protótipo experimental voltado à geração e utilização de um campo magnético alternado capaz de induzir uma força eletromotriz, em um enrolamento de espiras, suficiente para acionar uma calculadora científica comum e um conjunto de leds. A metodologia pedagógica proposta proporciona a concepção de uma sala de aula permissiva à aprendizagem significativa, o que torna os discentes sujeitos ativos em sua formação. O modelo induz a possibilidade de significativas melhorias na assimilação do conteúdo, o que traz consigo a capacidade de construção eficaz e consciente do tecido social por parte do alunado das referidas graduações.

A new study of Nagrajomyces: with two new species proposed and taxonomic status inferred by phylogenetic methods
Authors: Zhuo Lan , Guo Mei-Jun , Wang Qiu-Tong , Zhou Hao , Piepenbring Meike , Hou Cheng-Lin
Published: October 2022

Nagrajomyces (incertae sedis, Ascomycota) is a monotypic genus with a previously unknown systematic position. In this report, two new species are proposed, Nagrajomyces fusiformis and Nagrajomyces laojunshanensis. These new taxa are proposed based on morphological characteristics evident via light microscopy and molecular data. Multi-locus phylogenetic analyses (ITS rDNA, nrLSU rDNA, RPB2, and TEF1-α) show that specimens recently collected in Yunnan Province, China are closely related to Gnomoniaceae. Both new species and known species were discovered repeatedly in their asexual developmental form exclusively on twigs of Rhododendron spp. (Ericaceae). This indicates a host specificity of Nagrajomyces spp. for species of Rhododendron.
When will the hydrogen economy arrive?
Authors: Moriarty Patrick , Honnery Damon
Published: October 2022

The arrival of the hydrogen (H2) economy has been the subject of many studies. Earlier articles were over-optimistic about the timing and extent of global H2 uptake, and predicted private vehicles as leading the way to a H2 economy. The recent strong rise in the global electric vehicle fleet has inevitably led to a reassessment of the prospects for H2, at least for transport. This review paper examines how researchers over recent decades have envisaged how the H2 economy would arrive, and why it was desirable, or even inevitable; it also looks at the future prospects for the H2 economy. The key findings are as follows:

● Among the leading energy forecasting bodies, particularly the International Energy Agency (IEA), even the most optimistic scenarios predict under 10% H2 penetration by 2050.

● IEA forecasts are very optimistic about the prospects for the introduction of carbon dioxide removal technologies and growth of dispatchable sources of low-carbon energy.

● More realistic IEA forecasts would increase the need for the growth of intermittent energy sources such as wind and solar. The subsequent requirement for energy storage would in turn help the case for H2 adoption.

● No new technologies are on the horizon to decisively tip the balance in favor of H2.

● It is concluded that a global H2 economy is still distant, but it could arise in energy-poor countries such as Japan and South Korea, and it could find a niche in freight transport.
Stochastic optimization model for ship inspection planning under uncertainty in maritime transportation
Authors: Yan Ran , Yang Ying , Du Yuquan
Published: October 2022

Maritime transportation plays a significant role in international trade and global supply chains. Ship navigation safety is the foundation of operating maritime business smoothly. Recently, more and more attention has been paid to marine environmental protection. To enhance maritime safety and reduce pollution in the marine environment, various regulations and conventions are proposed by international organizations and local governments. One of the most efficient ways of ensuring that the related requirements are complied with by ships is ship inspection by port state control (PSC). In the procedure of ship inspection, a critical issue for the port state is how to select ships of higher risk for inspection and how to optimally allocate the limited inspection resources to these ships. In this study, we adopt prediction and optimization approaches to address the above issues. We first predict the number of ship deficiencies based on a k nearest neighbor (kNN) model. Then, we propose three optimization models which aim for a trade-off between the reward for detected deficiencies and the human resource cost of ship inspection. Specifically, we first follow the predict-then-optimize framework and develop a deterministic optimization model. We also establish two stochastic optimization models where the distribution of ship deficiency number is estimated by the predictive prescription method and the global prescriptive analysis method, respectively. Furthermore, we conduct a case study using inspection data at the Hong Kong port to compare the performances of the three optimization models, from which we conclude that the predictive prescription model is more efficient and effective for this problem.
Investigating the effect of cryogenic treatment of workpieces and tools on electrical discharge machining performance
Authors: Jatti Vijaykumar S , Khedkar Nitin K , Jatti Vinaykumar S , Dhall Pawandeep
Published: October 2022

In this competitive world, manufacturers must embrace new technology in order to differentiate their products and capture market leadership. This can be achieved using advanced materials; however, these materials are difficult to machine by using traditional machining processes. A very viable and practical unconventional machining process is electrical discharge machining (EDM). EDM processes need proper selection of input parameters to get optimum productivity aspects, namely, the material removal rate and tool wear rate. Thus, the present study aims at investigating the effect of cryogenically treated work pieces and tools, gap currents, gap voltages, pulse on time and pulse off time on the material removal rate and tool wear rate during EDM of Nitinol (NiTi) alloy, Monel (NiCu) alloy and beryllium copper (BeCu) alloy. The experimental results showed that cryogenic treatment significantly improved the electrical conductivity of the workpieces and tool electrodes, which resulted in an enhanced material removal rate and reduced tool wear rate.

Published: October 2022

This study examines the role of political stability in a firm's financial performance in Bangladesh. By considering 139 listed companies from the Dhaka Stock Exchange over the period of 2011 to 2020, we applied a dynamic generalized method of moments (GMM), dynamic quantile regression and dynamic threshold regression. The empirical evidence of this study shows a significant positive impact of political stability on Bangladeshi firms' financial performances. Using dynamic quantile regression, we found a positive impact of political stability in the firms' upper and lower quantiles. Additionally, we found the threshold effect of political stability on the firms' performance to have a score of 13.680. This study contributes theoretically and empirically by examining the importance of political stability on financial performance. For the investors, policymakers and other stakeholders, this study provides evidence of a threshold of political stability on a firm's financial performance.
Multi-Objective Adaptive Manta-Ray Foraging Optimization for Workflow Scheduling with Selected Virtual Machines Using Time-Series-Based Prediction
Authors: Singh Sweta , Kumar Rakesh , Rao Udai Pratap
Published: October 2022

Optimization problems are challenging, but the larger challenge is to deal with the energy issue of the cloud, with continuous dynamic load and fluctuating VM performance. The optimization technique aids in efficient task-resource mapping ensuring optimal resource utilization with minimum active hosts and energy consumption. Existing works focused on time-invariant and bounded VM performance with major concentration on minimizing the execution cost and time. A multi-objective adaptive manta-ray foraging optimization (MAMFO) has been proposed in the paper for efficient scheduling with optimum resource utilization and energy consumption. The paper contributes by considering the time-varying VM performance and performance prediction using a dynamic time-series based ARIMA model, filtering out the VMs with larger fluctuating possibility, and employing only the selected VMs to be scheduled using MAMFO to meet the optimization goal with minimum SLA violations. The experimental analysis improves the work efficiency (e.g., energy consumption attained to be 0.405 kWh, and 5.97% of SLA violations).

Profit Sharing in Multinational Corporations
Authors: Eisemann Charles W.
Published: October 2022

Multinational corporations are proliferating through­out the world. They are coming not only from the United States, but from Europe and Asia as well. The purpose of this article is to build a case around which is based the concept that profit sharing may be a force which will enable multinational corporations to transcend local situations and bring all employees to work for the benefit of the parent corporation, regardless of the corporation's nationality. The author recognises that local nationalism will always play an extremely important part in the eyes of employees and that corporate citizenship will con­tinue to be secondary. However, it is clearly apparent that the influence of the multinational corporation is only beginning to be felt, and when combined with the influences of transnational unionism, corpora­tions must begin to find newer and better ways of bringing employees under the corporate umbrella and working for the good of the corporation. A force which can provide one meaningful step in that direction is sharing the profits of the enterprise.

Разрешение особенностей пространств орбит $G_{n,2}/T^n$
Authors: Buchstaber Victor Matveevich , Terzic Svjetlana
Published: October 2022

Изучается пространство орбит $X_n = G_{n,2}/T^n$ стандартного действия компактного тора $T^n$ на комплексном многообразии Грассмана $G_{n,2}$. Описана структура множества критических точек $\operatorname {Crit}G_{n,2}$ обобщенного отображения моментов $\mu _n: G_{n,2}\to \mathbb {R}^n$, образом которого является гиперсимплекс $\Delta _{n,2}$. Каноническая проекция $G_{n,2}\to X_n$ переводит множество $\operatorname {Crit} G_{n,2}$ в множество $\operatorname {Crit}X_n$, состоящее по определению из орбит $x\in X_n$ с нетривиальной стационарной подгруппой в $T^{n-1}=T^n/S^1$, где $S^1\subset T^n$ - диагональный одномерный тор. В терминах пространств параметров орбит введено понятие особой точки $x\in \operatorname {Sing}X_n \subset X_n$. Доказано, что множество $Y_n = X_n\setminus \operatorname {Sing}X_n$ является открытым многообразием, всюду плотным в $X_n$. Показано, что $\operatorname {Crit}X_n \subset \operatorname {Sing}X_n$ для $n>4$, но $\operatorname {Sing}X_4\subset \operatorname {Crit}X_4$. Центральным результатом является построение проекции $p_n: U_n= \mathcal {F}_n\times \Delta _{n,2}\to X_n$, $\dim U_n = \dim X_n$, где $\mathcal {F}_n$ - универсальное пространство параметров. Ранее авторами было доказано, что $\mathcal {F}_n$ - замкнутое гладкое многообразие, диффеоморфное известному многообразию $ \overline {\mathcal {M}}(0,n)$. Показано, что отображение $p_n: Z_n = p_n^{-1}(Y_n)\to Y_n$ является диффеоморфизмом, и описана структура множеств $p_n^{-1}(x)$ для $x\in \operatorname {Sing}X_n$.

Для любого фактора получен эквивариантный гомеоморфизм, обобщающий известную конструкцию Дэвиса-Янушкевича для квазиторических многообразий и малых накрытий. Доказана формальность пространства соответствующей конструкции Бореля при естественном предположении о действии группы в комплексном случае, что приводит к новому описанию эквивариантных когомологий факторов по любым координатным подгруппам. Показано, что ослабленная гипотеза о торическом ранге выполнена для любого частичного фактора момент-угол-комплекса по действию диагональной окружности. Также предложена явная конструкция, показывающая, что целочисленные когомологии частичных факторов момент-угол-многообразий по действию окружности могут иметь произвольное кручение.
Exploring the vulnerability of a commonly exploited fish stock, Galeoides decadactylus in the artisanal mixed capture fisheries of Sierra Leone
Authors: Konoyima Komba Jossie , Showers Percival Arthur Timothy
Published: October 2022

Galeoides decadactylus is a commonly exploited fish stock in Sierra Leone, and the study of its vulnerability to capture in the artisanal mixed fisheries of Sierra Leone has not gained the needed attention of researchers, for which the present study has come in handy particularly when such information is critical for sustainable management of the stock. The study utilized length-frequency data obtained from 865 specimens as input datasets of analytical models inscribed for the FAO Fish Stock Assessment Tool (FiSAT II) software. Vulnerability indices for this study were the Length Structured Virtual Population Analysis (LVPA) and the Probability of Capture (PC). Results revealed minimum and maximum total length of 11cm and 36cm respectively for the study species, and LVPA showed highest catch (in numbers) for the length range, 20 cm (n = 94, 0000) - 21 cm (n = 100, 000). Also, the probability of capture evinced greater selection probability (p = 0.9) of the larger sizes (17cm - 22 cm (mean, 19.5 cm TL) at a maximum mesh size of 8cm of bottom drift net utilised by the fishers. The results of LVPA implied that the smaller length groups of the assessed stock (TL  are less vulnerable to fishing mortality, but most susceptible to natural mortality, and the probability of capture indicated that the gill nets used by the artisanal fishers for this study were highly selective to allow greater number (n = 4.8 x 106) of the smaller length group escape capture. In conclusion, G. decadactylus was efficiently exploited in the artisanal mixed fisheries. However, stringent measures on capture input and output controls are advised for the assessed stock.

Authors: Fanan, A. G., Uzoigwe, M. C., Ategwu, P. O., Kenn-Aklah, F. U.,
Published: October 2022

This study investigated the availability and utilization of instructional technologies in supervision in public secondary schools in Cross River State, Nigeria. To achieve the purpose of this study, descriptive survey research design was adopted; a research question was raised and two hypotheses were formulated to guide the study. The population of this study comprised the entire 279 respondents drawn through census approach from all the public secondary schools in Cross River State.Data collection was carried out with the use of researchers’ constructed instrument titled: Availability and Utilization of Instructional Technologies in School Supervision during COVID-19Pandemic Survey (AUITSSCOVID-19PS). The instrument was validated and reliability was established through Cronbach Alpha analysis which yielded .90 hence indicating high internal consistency in achieving the purpose of this study. In order to answer the research question, data collected were analyzed using mean and standard deviation while the hypotheses were tested with independent t-test statistical techniques. The results showed that the availability of instructional technologies used in school supervision is very low. It was also found that the extent of utilization of instructional technologies in school supervision is very low. Based on the findings and discussion, conclusions were made. It was therefore recommended among others that the government should ensure that adequate instructional technologies are provided and utilized in supervising secondary schools especially during this period of global COVID-19 pandemic.

To carry out this study, three research objectives that were later translated to hypotheses were generated on the basis of age, gender, level of education, and belief, to guide the research. Literature relating to the variables selected were reviewed to cover both conceptual and empirical sources. The Ex-post facto research design was utilized for the study. A sample of 461 respondents was drawn from six university libraries using the purposive (census) sampling technique. A structured questionnaire titled, ‘Socio-demographic Variables and Utilization of Information and Communication Technology for Library services (SDVUICTLS)’ was used as the main instrument for data collection. The tool was subjected to face and content validation by experts in Test, Measurement and Evaluation Faculty of Education, University of Calabar. The reliability coefficient ranged from 0.75 to .88 and was established through Cronbach’s Alpha method. The hypotheses were tested at .05 alpha levels. The data analysis techniques used were One-way Analysis of Variance (ANOVA), and independent t-test. The results of data analyses revealed that age (F=8.195), level of education (F = 5.232), belief (F = 4.242), significantly influenced utilization of ICT by library staff in the university libraries, while there was no significant influence of gender t=.252) on the utilization of ICT by library staff for library services. Based on these findings, it was recommended that library management/ parent institutions should embark on aggressive training and retraining of staff especially those that are 40 years and above with special reference to utilization of ICT for provision of services in the libraries.  The study equally recommended that Librarians should make personal effort to train themselves with or without the assistance of the management because this will make them to be more relevant and effective in delivering library services to the library users

Child adoption in Nigeria is still an evolving process .The enactment of the Child's Right Act in Nigeria has legalized child adoption. The Objective of this study include to access the perception of child adoption in Nigeria; to determine the challenges of child adoption in Nigeria, and to investigate the prospects of child adoption in Nigeria. The method used was to explore secondary data, policy documents, existing studies and reviews from scholars, local and international organizations. Perception of child adoption slightly vary across the country, with most Nigerian having fair knowledge of the term “child adoption”  which does not translate into its practice .It was also shown that infertility is the main factor that has influenced the rate of willingness and acceptability of child adoption in Nigeria. However, the ideology that biological ties are fundamental to family relations is associated with several stigmatizing beliefs about adoption, which may cause both the adoptee and the adoptive parents to feel socially marginalized and devalued. Just like other part of the world, child adoption in Nigeria is faced with several challenges ranging from stigmatization, unknown parental background, possible inherited or genetic diseases, psychological and religious beliefs, poverty, establishment of illegal adoption and orphanage homes, future claim by the biological parents, disloyalty or abandonment of adoptive parents the child when the child learns that he or she was adopted. The future prospects of child adoption lie in Nigerians taking seriously the principles and standards enunciated in the international adoption law of Nigeria that the best interest of children (which include their survival, development, protection and participation) should be the guiding principle in the whole adoption process. In conclusion , the perception, challenges and prospects of child adoption reviewed in this study shows child adoption in Nigeria is still evolving and requires the government, churches, other religious bodies, NGOs, individuals and the public at large to join hands in welcoming and implementing the right practices of child adoption, as well as ‘Child's Right Laws' .

Lymphoma is the second most common gastric cancer, following gastric adenocarcinoma. Most gastric lymphomas are mucosa-associated lymphoid tissue lymphomas or diffuse large B-cell lymphomas. Primary gastric Burkitt’s lymphoma is a subtype of non-Hodgkin lymphoma and represents an aggressive and rare malignity with the fewest cases reported globally. Primary gastrointestinal non-Hodgkin lymphoma is a rare condition. Burkitt’s lymphoma is an aggressive form of B-cell lymphoma endemic to Africa while it is not endemic to the rest of the world. Here we presented a young immunocompetent male patient who had weight loss and was admitted with a stomachache. Upper gastrointestinal endoscopy and biopsy detected a large primary gastric Burkitt’s lymphoma. While long-term survival rates are possible with early diagnosis and timely appropriate treatment, delay in treatment can be fatal for such patients.

Published: October 2022

In recent years, many researchers have been using computer-based systems containing artificial intelligence applications for different applications. Human recognition application is one of the studies carried out in this field. Face and object recognition applications, which were originally designed for security measures, are also used in the entertainment and shopping sectors recently. These applications are gaining even more popularity with the mobile application development of various companies. In face recognition applications, deep learning methods can be preferred if the data is large and complex. In this study, a 3-layer Convolutional Neural Network (CNN) has been developed for a face recognition application. The developed model was applied to the Libor Spacek's Facial Images Databases dataset. As a result of the application of the proposed method on the data set, it was determined that the accuracy rate was 99.29%. This means that the application can be adapted for real recognition systems.
Auto-detection of Intermetallic and Eutectic Phases in Microstructure of the AZ91 Mg-alloys by Image Processing Techniques
Authors: ELEN Abdullah , ELEN Levent
Published: October 2022

AZ91, which is used in the production of parts in the aerospace, defense and automotive industries, can be enhanced by the addition of an alloying element or the cooling rate, due to the weak strength and formability properties of advanced technology Mg-alloys. The microstructure change in Mg alloys significantly affects the mechanical properties. By analyzing the microstructure of these alloys, a close estimate of the mechanical properties can be made. In this study, an image processing-based model is proposed that automatically recognizes the intermetallic and eutectic phases required for the analysis of microstructural properties in AZ91 Mg-alloys. The proposed method consists of two stages; In the first step, the eutectic phase template is obtained as a binary image. In the second step, the binary image containing the intermetallic and eutectic phases is obtained and the result image with only the intermetallic phases is obtained by taking the difference of these two patterns. Experimental studies have shown that the proposed method gives a result close to the real value in the detection of eutectic phases.

As disciplinas escolares e os livros didáticos como expressões da cultura escolar:
Authors: Mello Bruno Falararo de , Pezzato João Pedro , Costa Chrstiane Fernanda da
Published: October 2022

Os livros didáticos estão intrinsecamente ligados à escola, pois são, eles próprios, expressões da cultura escolar. Neste artigo, apresentam-se algumas considerações acerca da constituição das disciplinas escolares, em uma perspectiva histórica, a partir do advento da escola dita moderna, tomando-se como exemplo a Geografia escolar. As disciplinas escolares são analisadas como criações originais e espontâneas da escola, detentoras de uma finalidade que vai além da mera transmissão de conteúdos acadêmicos. Elas são vistas no papel de produtoras de conhecimentos próprios e originais da cultura escolar, que intercambiam com os saberes produzidos pelas ciências de referência, mas que não se confundem com eles em seus objetivos. Os livros didáticos são tomados em seu papel de materializadores da cultura escolar. Os manuais registram o patrimônio cultural que identifica as histórias e elementos de determinadas comunidades. Eles têm servido para padronizar conteúdos e métodos de ensino, formalizar currículos, apontar normas de conduta desejadas e orientar os trabalhos dos docentes. Além dos aspectos ligados às práticas de ensino, eles se prestam, primordialmente, ao assentamento e à estabilidade das próprias disciplinas escolares.

School subjects and textbooks as expressions of school culture: some theoretical considerations
Abstract
School subjects and textbooks are intrinsically linked to school, as they are themselves school culture expressions. In this article, we presente some considerations about the school subjects constitution, in a historical perspective, from the advent of the so-called modern school, taking as na example school geography. School subjects are analyzed as original and spontaneous school creations, holding a purpose that goes beyond just transmission of academic content. They are seen in the role of producers of own and original knowledge of the school culture, which interchange with the knowledge produced by the reference sciences, but which are not confused with them in their objectives. Textbooks are taken in their role as materializers of school culture. They have been used to standardize content, formalize curricula, point out desired standards of conduct and guide the work of teachers. In addition to the aspects linked to teaching practices, they are primarily used for the settlement and stability of the school subjects themselves.
