Por que Ensinar Astronomia nos Ensinos Fundamental e Médio
Authors: MADUREIRA ALEXANDRE MAGNO DE AMORIM
Published: May 2024

Este trabalho tem por objetivo avaliar as vantagens e a importância da introdução de Astronomia no ensino regular, como fator de motivação para o conhecimento científico. No contexto geral, os conteúdos de Astronomia são ministrados nas disciplinas de Ciências, Geografia e História. No entanto, muitas vezes os professores não têm formação adequada para ministrá-los com a competência e a maestria necessárias. Constata-se assim que, na prática, grande parte dos alunos da rede pública de ensino deixa o ciclo básico de estudos sem o conhecimento de conceitos astronômicos pertinentes a uma formação científica adequada. É bom salientar que esse conhecimento é capaz de trazer vantagens para a formação do indivíduo, que vão desde a compreensão de princípios básicos da natureza até o estímulo a uma futura carreira nas áreas de ciência e tecnologia. Demonstramos que com oficinas de Astronomia somos capazes de melhorar o desempenho desses alunos e potencializar suas habilidades de aprendizagem.
APPLICATION OF ARTIFICIAL INTELLIGENCE IN HIGHER EDUCATION INSTITUTIONS: FOREIGN EXPERIENCE
Authors: Bobro Natalia
Published: May 2024

The purpose of this article is to study the application of artificial intelligence in higher education institutions in foreign countries. The article provides an overview of various tools for using artificial intelligence in the educational environment, reveals examples of successful implementation of digital technologies in higher education institutions, and outlines the shortcomings that should be taken into account when introducing artificial intelligence into educational practice. Methodology. The study used a set of complementary methods based on the principles of general scientific methodology: theoretical methods of analysis, synthesis and generalisation of works corresponding to the stated topic. Theoretical analysis allowed the identification of theoretical concepts, models and technologies used to support the educational process. The method of synthesis enabled the information obtained to be put into a systematic and comprehensible form. By synthesising different sources and data, a general idea of how artificial intelligence can be used in modern education was formed. The method of synthesis helped to build a system of existing knowledge and experience in this area and identify new areas of research. Results. The creation of individualised experiences using artificial intelligence and machine learning has been shown to tailor learning to the individual characteristics of the student, increasing the effectiveness of training. Personalised learning technologies are used to improve the learning process through data mining and the provision of personalised information. Personalised learning can also use methods such as games and virtual activities to make the learning process more interesting and engaging. Disadvantages include insufficient technological development, lack of personal contact, limited AI in the curriculum, limited creativity and flexibility of systems, algorithmic discrimination and loss of skills. Despite these shortcomings, it is noted that the use of intelligent learning systems and adaptive technologies allows for the personalisation of learning based on the individual characteristics of each student, which contributes to more effective training. It is important to find an optimal balance between the traditional approach to learning and the use of the latest learning technologies that will contribute to successful and productive learning. Practical implications include the importance of personalising learning with the help of intelligent systems, the need to find a balance between traditional and modern methods, taking into account the shortcomings of technology implementation, continuing research and developing partnerships for the successful implementation of artificial intelligence in educational practice. Value/Оriginality. The paper proposes specific methods and examples of artificial intelligence application in education, analyses the shortcomings of this process and provides practical recommendations for its further improvement.

Published: May 2024

Cardiovascular Disease (CVD) account for a large portion of the global health burden and are one of the main causes of decease worldwide. In the classification and forecasting of CVDs, Machine Learning (ML) techniques have demonstrated encouraging outcomes. In this research report, a comparative analysis of classification and prediction models for CVD is presented, including both linear and ensemble ML approaches. The paper compares ensemble models like Catboost, Histogram Gradient Boosting Machine (HGBM), and Extra Trees against linear models like Gaussian Nave Bayes, SVM, and KNN. The objective is to identify the most effective CVD prediction model by assessing its performance through accuracy, precision, sensitivity and F1 score as key evaluation metrics. Moreover, results show that ensemble models outperform linear models using advanced techniques such as boosting and histogram-based algorithms. The results underscore the critical role ensemble models play in accurately diagnosing and predicting cardiovascular disease and provide important new information to researchers and healthcare providers. Using these models has the potential to significantly improve patient outcomes and health management by enabling early detection and intervention

Games of Collaboration
Authors: Reed Adam
Published: May 2024

This paper looks at the theme of collaboration through the prism of game design, and especially the example of serious games. At its heart, this is a consideration  of two collaborative projects between experts. The first is a current collaboration between computer scientists, game designers, and a theatre company in Scotland, in which the author is also a collaborator and the project’s ethnographer. The second is perhaps the largest and most high-profile collaborative project recently led and documented by anthropologists, Meridian 180, which aims to experiment with the norms of collaboration itself, and which has already been theorised and extensively reflected upon by one of its founders, Annelise Riles. The paper aims to put these two collaborations into some kind of conversation in order to throw each into productive relief and to ask some new questions about how we think about both the exercise of collaboration and the deliberate subversion of its norms.

International Children and the Institutional Infrastructures of Schools in Finland
Authors: Korpela Mari
Published: May 2024

Growing numbers of children are moving between countries because of their parent(s)’ careers. The temporary labour migration of highly educated professionals – sometimes called career expatriates or transnational corporate elites (Amit 2002; Fechter 2007) – is increasing in various parts of the world. Finland, among many countries, welcomes such professionals both because they offer skills that are needed in the global competitive markets and because the country’s domestic population is ageing. Often, these professionals do not intend to stay permanently but rather to return to their native countries or move on to other locations after a few years.
The international professionals are often accompanied by their spouses and children. In this paper, I focus on a central institutional infrastructure in these children’s lives, namely education and schools. I elaborate on international schools in Finland, and on the children’s position within this infrastructure. The paper is based on extensive ethnographic research in an international school in a Finnish town.
Tracing Infrastructure and its Evolution in the Search for the Missing in Poland
Authors: Matyska Anna
Published: May 2024

Every day around the globe, people go missing for any number of reasons. Some disappearances are intentional, others are enforced by oppressive political regimes or the result of natural disasters. Whatever the reason, these disappearances produce family ruptures and anxieties, and require a search to establish, at the very least, whether the missing person is dead or alive. In Poland, the number of reported disappearances gradually rose to 20 000 by 2018. (For comparison, other countries’ figures vary widely due to the diverse contexts and calculations used—for instance, Finland records 700–800 missing incidents annually, while in the UK there are over 300 000.) The increase in Poland’s figures results from the sheer growth in disappearances given the ease of movement and rising socioeconomic pressures, bringing with them health issues, debt, and family conflicts. The increase in disappearance figures also results from an increased willingness among families to report missing persons and a willingness among the police to accept such reports. I associate the rising sociopolitical recognition of disappearances in Poland with the expansion of tracing infrastructure, which I define as the interlocking assembly of state and nonstate agents, institutions, and technologies engaged in the search for missing persons.

Missing persons and infrastructures of search and identification
Authors: Huttunen Laura
Published: May 2024

People go missing all over the world, but the reasons for disappearances are enormously diverse. Some people are intentionally disappeared by the state: totalitarian and military governments as well as various paramilitary and criminal organizations have used enforced disappearances as a tactic to control the population and create submissive citizens or subjects though fear and insecurity. Both civilians and soldiers disappear invariably in the chaotic circumstances of war and armed conflict. Some people disappear in natural catastrophes or fatal accidents; some disappear of their own free will. Whatever the reason for disappearance, it disturbs the everyday flow of life in families and communities, and in many places, it creates anomalies for modern state bureaucracies. Unaccounted-for absences give rise to search practices, but the circumstances of search are radically different in different places and different contexts of disappearance. One way to approach these differences is to analyse the infrastructures of search in each site. I am especially interested in the entanglement of the local with the global, and of the spatial reach of search infrastructures . Moreover, I consider the significance of the material affordances of some infrastructural forms, especially of the DNA as the key tool for identification. I make some observations on how the entanglements of local and transnational investment and the material affordances of the techniques allow some of the disappeared to be found and identified, while others stay more ‘disappearable’ (Laakkonen 2022).

2 • Storiografia e analisi nel dibattito epistemologico degli anni Settanta
Authors: Vagelli Matteo
Published: May 2024

Il capitolo si apre con la ricostruzione dei termini del dibattito sulla natura e sui limiti della scienza, con particolare attenzione ad alcune posizioni italiane, a metà degli anni Settanta. Col vaglio di diverse prospettive storiografiche e approcci metodologici si definisce la possibilità di un approccio storico-analitico al problema della scienza e del sapere. Si ipotizza il passaggio da un’analisi in termini storico-dialettici propria del marxismo ad una linguistico-epistemologica, la cui possibilità è situata ne Il sapere senza fondamenti di Gargani e nella filosofia di Wittgenstein.

Published: May 2024

Pitching is a major part of baseball, so much so that it can be said to be the beginning of baseball. Analysis of accurate pitching motions is very important in terms of performance improvement and injury prevention. When analyzing the correct pitching motion, the currently used motion capture method has several critical environmental drawbacks. In this paper, we propose analysis of pitching motion using the RGB-based Human Pose Estimation (HPE) model to replace motion capture, which has these shortcomings, and use motion capture data and HPE data to verify its reliability. The similarity of the two data was verified by comparing joint coordinates using the Dynamic Time Warping (DTW) algorithm.
Anomaly Detection in Livestock Environmental Time Series Data Using LSTM Autoencoders: A Comparison of Performance Based on Threshold Settings
Authors:   Korean Institute of Smart Media, Chung Se Yeon , Kim Sang Cheol
Published: May 2024

In the livestock industry, detecting environmental outliers and predicting data are crucial tasks. Outliers in livestock environment data, typically gathered through time-series methods, can signal rapid changes in the environment and potential unexpected epidemics. Prompt detection and response to these outliers are essential to minimize stress in livestock and reduce economic losses for farmers by early detection of epidemic conditions. This study employs two methods to experiment and compare performances in setting thresholds that define outliers in livestock environment data outlier detection. The first method is an outlier detection using Mean Squared Error (MSE), and the second is an outlier detection using a Dynamic Threshold, which analyzes variability against the average value of previous data to identify outliers. The MSE-based method demonstrated a 94.98% accuracy rate, while the Dynamic Threshold method, which uses standard deviation, showed superior performance with 99.66% accuracy.
Deep learning-based clothing attribute classification using fashion image data
Authors:   Korean Institute of Smart Media, Jeong Hye Seon , Lee So Young , Lee Choong Kwon
Published: May 2024

Attributes such as material, color, and fit in fashion images are important factors for consumers to purchase clothing. However, the process of classifying clothing attributes requires a large amount of manpower and is inconsistent because it relies on the subjective judgment of human operators. To alleviate this problem, there is a need for research that utilizes artificial intelligence to classify clothing attributes in fashion images. Previous studies have mainly focused on classifying clothing attributes for either tops or bottoms, so there is a limitation that the attributes of both tops and bottoms cannot be identified simultaneously in the case of full-body fashion images. In this study, we propose a deep learning model that can distinguish between tops and bottoms in fashion images and classify the category of each item and the attributes of the clothing material. The deep learning models ResNet and EfficientNet were used in this study, and the dataset used for training was 1,002,718 fashion images and 125 labels including clothing categories and material properties. Based on the weighted F1-Score, ResNet is 0.800 and EfficientNet is 0.781, with ResNet showing better performance.

A Study on Key Arrangement of Virtual Keyboard based on Eyeball Input system
Authors:   Korean Institute of Smart Media, Lee Sa Ya , Hong Jin Gyeong , Lee Joong Sup
Published: May 2024

The eyeball input system is a text input system designed based on ‘eye tracking technology' and ‘virtual keyboard character-input technology'. The current virtual keyboard structure used is a rectangular QWERTY array optimized for a multi-input method that simultaneously utilizes all 10 fingers on both hands. However, since ‘eye-tracking technology’ is a single-input method that relies solely on eye movement, requiring only one focal point for input, problems arise when used in conjunction with a rectangular virtual keyboard structure designed for multi-input method. To solve this problem, first of all, previous studies on the shape, type, and movement of muscles connected to the eyeball were investigated. Through the investigation, it was identified that the principle of eye movement occurs in a circle rather than in a straight line. This study, therefore, proposes a new key arrangement wherein the keys are arranged in a circular structure suitable for rotational motion rather than the key arrangement of the current virtual keyboard which is arranged in a rectangular structure and optimized for both-hand input. In addition, compared to the existing rectangular key arrangement, a performance verification experiment was conducted on the circular key arrangement, and through the experiment, it was confirmed that the circular arrangement would be a good replacement for the rectangular arrangement for the virtual keyboard.

Introdução: as lesões por fricção são definidas como feridas traumáticas resultantes de fricção, contusão ou cisalhamento da pele. Estes agravos são comuns em idosos, apresentando potencial de tornarem-se feridas de difícil cicatrização. A epidemiologia destas ainda não é totalmente esclarecida, desta forma, estudos com esta finalidade são pertinentes.  Objetivo: identificar a prevalência pontual de lesão por fricção, bem como, os fatores associados a este agravo, em pacientes internados em um hospital universitário público da Região Centro-Oeste do Brasil. Método: estudo transversal, de prevalência pontual, realizado em junho de 2022. Desenvolvido com 23 pacientes internados no setor de Clínica Médica, de um hospital vinculado ao Sistema Único de Saúde. Destes, 7 foram identificados em risco para o desenvolvimento de lesão por fricção. Os dados foram coletados através de exame físico da pele e das informações presentes nos prontuários. Para análise dos dados, utilizou-se estatística descritiva simples, com cálculo de médias e percentuais. Resultados: a idade média encontrada dos pacientes internados foi de 52,3 anos, sendo a maioria dos pacientes do sexo masculino (52,1%). A prevalência pontual de lesão por fricção encontrada foi de 57,2%, sendo comum nos pacientes comorbidades, assim como, alterações nutricionais. Conclusão: a prevalência encontrada foi elevada. Identificou-se que as condutas e intervenções para a prevenção e tratamento destas lesões não estavam adequadas. Estes achados denotam a necessidade de ações educativas sobre o tema. Novos estudos semelhantes podem contribuir para o aumento na visibilidade e construção de documentos e políticas públicas relacionados ao tema.

Artificial Intelligence and Educational Measurement: Opportunities and Threats
Authors: Ho Andrew D.
Published: May 2024

I review opportunities and threats that widely accessible Artificial Intelligence (AI)-powered services present for educational statistics and measurement. Algorithmic and computational advances continue to improve approaches to item generation, scale maintenance, test security, test scoring, and score reporting. Predictable misuses of AI for these purposes will result in biased scores, construct underrepresentation, and differential impact over time. Recent efforts to develop standards for AI use in testing like those of Burstein are promising. I argue that similar efforts to develop AI standards for educational measurement will benefit from increased attention to the context of test use and explicit commitment to ongoing monitoring of bias and scale drift over time.
Ferroptosis and Lipid Metabolism in Acute Myocardial Infarction
Authors: Wu Xinyu , Li Jingru , Cheng Huan , Wang Luqiao
Published: May 2024

Acute myocardial infarction (AMI) is triggered by the blockage of coronary arteries, leading to restricted blood flow to the myocardium, which results in damage and cell death. While the traditional understanding of cell death primarily revolves around apoptosis, a new player in the game has emerged: ferroptosis. This novel form of cell death relies on iron and is propelled by reactive oxygen species (ROS). Lipid metabolism, an indispensable physiological process, plays a vital role in preserving cellular homeostasis. However, when this metabolic pathway is disrupted, the accumulation of excess waste increases, specifically lipid peroxides, which are strongly linked to the occurrence and progression of AMI. As a result, comprehending this complex interaction between ferroptosis and lipid metabolism could pave the way for new therapeutic approaches in tackling AMI.

Published: May 2024

Background: The coronary no-reflow (NR) phenomenon is an independent predictor of major adverse cardiac events (MACEs). This study aimed to establish a clinical and comprehensive nomogram for predicting NR in acute myocardial infarction (AMI) patients after primary percutaneous coronary intervention (pPCI). Methods: The multivariable logistic regression analysis was performed to determine the NR-related factors. A nomogram was established via several clinical and biochemical factors, and the performance was evaluated via discrimination, calibration, and clinical factors. Results: The study consisted of 3041 AMI patients after pPCI, including 2129 patients in the training set (70%) and 912 patients in the validation set (30%). The NR event was 238 in the training set and 87 in the validation set. The level of N-terminal prohormone B-type natriuretic peptide (NT-proBNP), basophil count (BASO), neutrophil count (NEUBC), D-dimer, hemoglobin (Hb), and red blood cell distribution width (RDW.CV) in NR patients showed statistically significant differences. In the training set, the C-index was 0.712, 95% CI 0.677 to 0.748. In the validation set, the C-index was 0.663, 95% CI 0.604 to 0.722. Conclusions: A nomogram that may predict NR in AMI patients undergoing pPCI was established and validated. We hope this nomogram can be used for NR risk assessment and clinical decision-making and significantly prevent potentially impaired reperfusion associated with NR.

Published: May 2024

Background: Revascularized patients still experience adverse cardiovascular events. This is particularly true for elderly patients over the age of 65, as they often have more co-morbid vascular conditions. It is important to develop a tool to assist clinicians in comprehensively assessing these patients’ prognosis. The objective of this study is to create a comprehensive visual nomogram model combining clinical and physiological assessments to predict outcomes in elderly patients undergoing percutaneous coronary intervention (PCI). Methods: This study is a retrospective investigation of patients who underwent PCI between January 2016 and December 2017. A total of 691 patients with 1461 vessels were randomly divided into a training (n = 483) and a validation set (n = 208). A multivariate Cox regression model was employed using the training set to select variables for constructing a nomogram. The performance of the nomogram was assessed through the receiver operating characteristic curve (ROC) and calibration curves to evaluate its discrimination and predictive accuracy. To further assess the clinical usefulness, Kaplan–Meier curve analysis and landmark analysis were conducted. Results: Independent risk factors, including diabetes mellitus (DM), post-PCI quantitative flow ratio (QFR), previous myocardial infarction (MI), and previous PCI, were contained in the nomogram. The nomogram exhibited a good area under the curve (AUC) ranging from 0.742 to 0.789 in the training set, 0.783 to 0.837 in the validation set, and 0.764 to 0.786 in the entire population. Calibration curves demonstrated a well-fitted curve in all three sets. The Kaplan–Meier curves showed clear separation and the patients with higher scores in the nomogram model exhibited a higher incidence of target vessel revascularization (TVR) (7.99% vs. 1.24% for 2-year, p < 0.001 and 13.54% vs. 2.23% for 5-years, p < 0.001, respectively). Conclusions: This study has developed the visually intuitive nomogram to predict the 2-year and 5-year TVR rates for elderly patients who underwent PCI. This tool provides more accurate and comprehensive healthcare guidance for patients and their physicians.
Unlocking A Global Ocean Mixing Dataset: toward Standardization of Seismic-derived Ocean Mixing Rates
Authors: Wei Jingxuan , Zhao Zeyu , Gunn Kathryn , Gulick Sean , Shillington Donna , Lowery Christopher
Published: May 2024

Turbulent mixing is vital for water transformation in the ocean and sustains the global thermohaline circulation. Despite decades of global observations using different platforms, our understanding of ocean turbulence is still limited. More observations are needed to better characterize the spatio-temporal distribution of mixing to reduce uncertainties in climate models. Marine seismic reflection surveys are an untapped data resource for high-resolution ocean turbulence observation. Turbulent mixing can be extracted from seismic data through horizontal internal wave slope spectra. However, to date, a standardized approach to prepare seismic data for this spectral analysis is still lacking, leading to insufficient consideration of the impact of noise on the resulting diffusivities. To address these issues, we perform a full-wavefield synthetic modeling and processing to reveal noise-induced overestimation of diffusivities. We further propose a widely applicable workflow and apply it to three field seismic surveys with increasing noise levels conducted in regions of different turbulence environments: ocean ridges, open ocean interior, and continental slope. The derived diffusivities are benchmarked against direct measurements around the region to show the fidelity of this seismic method. The extended observation records by seismic data across the Kauai Channel and away from Mid-Atlantic Ridges reveal the importance of topography in modifying the propagation of internal tides and the distribution of turbulent mixing in both near and far fields. Our proposed workflow marks a key advancement towards standardization of seismic-derived ocean mixing rates and holds the potential to unlock massive marine seismic reflection dataset worldwide for ocean mixing characterization.

Prevalence studies of dark chocolate may produce results similar to those observed after resistance exercise. The results examining the effects of dark chocolate ingestion on aerobic exercise performance are controversial. In addition, there is a choice in experiments with chronically consumed chocolate components (40 to 80 g) and large amounts of dark chocolate in studies to improve athletic performance. Therefore, the purpose of this study to verify the effect of acute supplementation of 80 g dark chocolate (70% cocoa) on performance on cycle ergometer test. Eleven healthy, physically active, but untrained men participated in the study. Two incremental cycle ergometer tests were performed to determine the peak power output (Ppeak) without chocolate supplementation (control condition, C) and with supplementation of 80 g of dark chocolate 70% cocoa (C70%) ingested orally two hours before the test. Variables such as heart rate (HR), blood glucose concentration [GLI], blood pressure (SBP/DBP), and rating of perceived exertion (RPE) were monitored. Data normality was verified by the Shapiro-Wilk test, and the results are presented as mean ± standard deviation (SD). The performance data of the tests and physiological variables were compared using Student's t-test for paired samples, adopting a significance level of P < 0.05. No statistical differences were found for Ppeak (238.0 ± 35.1 vs 250.9 ± 42.7 W) between conditions (C and C70%, respectively), as well as in the other variables. Therefore, we concluded that although the ingestion of 80 g of dark chocolate (70% cocoa) 2 hours prior the cycle ergometer test did not modify the peak power output, physiological and psychophysiological variables analyzed when presenting the average results, individual analysis demonstrated that this supplementation could be used to enhance peak power, which support individual as opposed to group analysis to evaluate performance responses to supplementation protocols.
CORPOS SOB TREINAMENTO DESPORTIVO: UMA (RE)LEITURA SÓCIO-HISTÓRICA DAS CIÊNCIAS DO ESPORTE
Authors: Silva Alan Camargo
Published: May 2024

Esta resenha se refere à obra “Além das próprias forças: origens e caminhos das ciências do esporte no Brasil entre as décadas de 1930 e 1980”, publicada pela editora CRV em 2023. Este livro escrito cuidadosamente pelo Prof. Dr. Quéfren Weld Cardozo Nogueira permite demarcar a necessidade de (re)pensar a construção das ciências do esporte por diferentes vozes do campo e referenciais teórico-metodológicos das Ciências Humanas e Sociais. Entende-se como o processo de historicidade deve ser levado em consideração ao analisar as ciências do esporte para além dos seus aspectos físico-orgânicos ou parâmetros estatístico-biomédicos. Assim, a construção sócio-histórica do treinamento aponta como os aspectos políticos, econômicos e socioculturais influenciam nas formas de atingir o desempenho atlético, como também na própria maneira de lidar com o esporte de alto rendimento. Nesse sentido, esse livro faz pensar como a área de Educação Física assume um papel fundamental na formação reflexiva e na racionalidade de intervenção de novos profissionais sensíveis também a outras variáveis que escapam da dimensão biológica. A leitura desse livro, portanto, indica como a Sociologia, História e Pedagogia do Esporte podem ser incorporadas, de modo aplicado, na atuação dos profissionais do esporte e, sobretudo, indubitavelmente, fazendo a diferença na vida laboral daqueles que atuam em diferentes instituições ligadas a esse tema. Em termos gerais, a obra do Prof. Dr. Quéfren Weld Cardozo Nogueira destaca a importância do contínuo exercício de revisitar criticamente a Educação Física, como também abrir frentes ou lançar novos olhares/interpretações de investigação científica e ação acerca do “treinar” na área.
THE GREAT REIMAGINING
Authors: Hocking Bree T.
Published: May 2024

While sectarian violence has greatly diminished on the streets of Belfast and Derry, proxy battles over the right to define Northern Ireland’s identity through its new symbolic landscapes continue. Offering a detailed ethnographic account of Northern Ireland’s post-conflict visual transformation, this book examines the official effort to produce new civic images against a backdrop of ongoing political and social struggle. Interviews with politicians, policymakers, community leaders, cultural workers, and residents shed light on the deeply contested nature of seemingly harmonized urban landscapes in societies undergoing radical structural change. Here, the public art process serves as a vital means to understanding the wider politics of a transforming public sphere in an age of globalization and transnational connectivity.
