Authors: Belko V. , Cheng Liu , Kalmykova Sofiya , Pechnikov Aleksey , Plotnikov Andrey
Published: February 2025

The aim of the study is to reveal the influence of the electrode configuration of metallized film capacitors on their characteristics and performance under conditions typical of power electronics. Presently used electrodes configurations are summarized, their benefits and disadvantages are ana-lyzed. We showed that currently used metallized film capacitors electrodes configurations, ensuring reliable self-heling, have too high equivalent resistivity. Authors propose to introduce a hybrid type of electrode for metallized film capacitors. We showed the influence of the capacitor electrodes on its performance under the conditions typical of power electronics and experimentally studied the effect of the electrode thickness on the breakdown strength. The breakdown strength of polymer films with var-ious metallization thickness was determined using common dielectric testing methodology. We found out that the breakdown strength follows Weibull distribution and slightly depends on vacuum sput-tered metal thickness, unlike previous studies results. The effects from the fracture of electrodes caused by electrical discharges occurring during self-healing of metallized film capacitors are demon-strated experimentally. It was established the prominent influence of electrical explosion and micro-arc destruction of metallized electrode on polymer film breakdown strength. The results of numerical and analytical calculations of equivalent electrode resistivity for various configurations are presented. Comparative calculations of the surface resistance and active area of segmented and hybrid electrodes showed the advantage of the latter. We experimentally established that at comparable process dura-tions the deposited energy for the fracture of hybrid electrodes was less than for segmented ones. Keywords: metallized film capacitor, breakdown strength, electrode configuration, equivalent series resistance, self-healing, profile metallization, segmented metallization.

materialismo histórico-dialético espinosano
Authors: Goldblum Kissel
Published: February 2025

O método reflexivo do autor da Ética é considerado uma anomalia na constelação filosófica de seu tempo. Ao negar o estatuto da transcendência e recusar qualquer privilégio gnoseológico do cogito cartesiano, inaugurou uma matriz teórica inédita, que rejeita “qualquer dissociação entre direito e poder” (Montang, 1998, p. 17). Este artigo é um ensaio, que pretende contribuir com a história da filosofia materialista, nas palavras de Negri, ainda pouco divulgada, ao identificar  algumas estruturas teórica-metodológicas da obra de Espinosa que, como propomos, são uma chave que nos auxiliam a compreender a novidade espinosana, como “antecessora do materialismo dialético” (Deborin, 1952, p. 14).
Deus enquanto fim ético
Authors: Gomes Carlos Wagner Benevides
Published: February 2025

A felicidade é um dos temas mais relevantes para a metafísica e para a ética filosófica remontando desde a antiguidade grega, com a noção de eudaimonia aristotélica. Na modernidade, o filósofo seiscentista holandês Benedictus de Spinoza (1632-1677) apresentou uma concepção sui generis sobre felicidade ou beatitude (beatitudo) a partir de uma ontologia segundo a qual Deus aparece como uma causa imanente e autoprodutora da realidade. No pensamento spinozano, Deus e Felicidade tornam-se fins éticos imanentes para o homem, uma vez que este deve reconhecer sua necessária união com Deus, a substância absolutamente infinita, e, nesse sentido, ele pode ser feliz ao conhecer a causa de todas as coisas. Neste artigo, analisaremos a questão da felicidade segundo a leitura e perspectiva de três obras do pensador holandês: Breve Tratado, Tratado da emenda do Intelecto e Ética.

Student-Produced Films in Laboratory Courses as Learning Incentive and Exam Option
Authors: Berglund Liv-Irene , Krause Kirsten
Published: February 2025

An increasingly digitalized society demands that both educators and students master the use of digital tools in all teaching and learning activities. In laboratory-based courses, the practical elements of teaching are difficult to digitalize without sacrificing the important hands-on experience, leaving the remaining components such as seminars, reports or exams as possibilities where the classical concepts can be supplemented or replaced by digital solutions. In this paper we report on the use of digital film production as an alternative option for written laboratory reports and a means to intensify the learning outcome from practical experiments. Films were produced by students of the Bachelor course “Green Biotechnology and Bioenergy” on selected parts of the course. Simple and budget-friendly measures were implemented to carry out the filming. The films replaced the laboratory reports for the respective experiments. A seminar served as an interactive platform for the students to present their films to their fellow students and exchange feedback before the films were assessed by evaluators as part of the examination. The pedagogical benefits of this teaching method and its suitability as an assessment form were later analyzed to shed light on the question if student-produced films are a promising way to impart digital expertise effectively while acquiring practical skills in an informative and creative manner. Beyond advocating student-produced films as a possible exam concept for practical courses, our article demonstrates that self-executed filming was able to provide a more creative, interactive, and thus more motivating teaching atmosphere with mutually advantageous learning experiences for all parties involved.
Consequences of Unbalanced Productivity Growth in India: Lessons from the Scandinavian Model
Authors: Kulkarni Kishore G. , Wague Cheick , Warrier P. Nandakumar
Published: February 2025

Unbalanced productivity growth with one sector lagging behind is seen to spur aggregate inflation in the Scandinavian model of inflation. In other models, unbalanced wage growth embodied in a wage rise shock arising from the home goods sectors is seen to lead to a contraction of the private competitive sector while leading to an expansion of the public sector. Such analyses at a disaggregated level can offer some insights into some puzzling and distressing developments in the Indian economy, namely sluggish growth in manufacturing output and a persisting low level of agricultural productivity. This paper adopts a three-sector model including manufacturing, services and agricultural activity which does give a pointer about addressing the maladies referred to above. Data show that while productivity in services shows a healthy trend, there is a large differential between wages in services and manufacturing. The model gives the result that a hike in service sector wages has a positive effect on manufacturing output, if the propensity to consume out of wage income is higher than from wage income. The surplus in agriculture also increases, consistent with movement of labour into services (not modelled here) and a rise in agricultural productivity.
Harnessing Convolutional Neural Networks for The Optimization of Anaerobic Digestion of Sugarcane Bagasse: A Novel Approach to Pretreatment Strategies and Microbial Activity Prediction
Authors: Kasulla Srinivas , Malik S J , Yadav Anjani , Kathpal Gaurav , Zafar Salman
Published: February 2025

This paper is aimed at verifying the effectiveness of CNN in optimizing anaerobic digestion with sugarcane bagasse, considering the enhancement of strategies for pretreatment and accurate prediction of microbial activity and biogas yield. The primary objective of this research work is to increase the utilization efficiency of anaerobic digestion systems along with boosted biogas production using convolutional neural networks for better forecasts and optimizing procedures. This paper discusses the prediction of microbial activity and biogas from the anaerobic digestion of sugarcane bagasse using convolutional neural networks. The experiments conducted here are similar to studies that have studied various types of feedstock pretreatments, such as AFEX, steam explosion, and alkaline treatments. Different architectures of CNNs are trained with feedstock characteristics, process operational parameters, and conditions-related information to predict the output of biogas production (Olatunji et al., 2021; Sharma et al., 2023). This also verifies that CNNs outperform classical machine learning models and algorithms, such as SVMs and regression, in the prediction of the biogas yield from sugarcane bagasse at an accuracy of 92% and F1 score of 0.90. It accurately assesses the pretreatment methods, temperature, and operational conditions that have a considerable impact on biogas production. This is an embodiment of AI in making it possible to improve predictability and optimize biogas production processes (Parvane et al., 2022; Gao et al., 2022). A work analysis revealed that CNNs enhance the anaerobic digestion process of sugarcane bagasse by improving better and more accurate forecasting abilities in comparison to the traditional models while handling complex data. Follow-up research studies about follow-up hybrid AI models to amplify further the role of AI in real-time monitoring and optimization of biogas production for sustainable bioenergy solutions may focus on large-scale industrial applications of such models (Blasi et al., 2023; Malik et al., 2020).

It is not easy to find the proper definition of talent for there is not one (right) answer to the question: ''What talent really means?'' There are a lot of various answers including many different conditions and criteria (time when talent has occured, behavioural characteristics or anticipation of the future behaviour, type of behaviour and so on). It is considered that there are as many as 160 definitions of talent (Cvetković-Lay, 1995), that speaks enough about the complexity of that question/phenomenon. Definition, or to say understanding talent as a phenomenon is relevant for all other stpes that should be taken later on: recognition, identification, education, etc. Talented child parents' or family's is crucial for all these phases. In distinction from some believes talented children could come from any family regardless educational level of parents, their social state, and (a) talented parents and so on. It is very important for parents to be supportive, and to offer stimulating and chalenging setting to their child so she/he could develop its potentials, but also positive characteristics as a person, self-respect and real image of his/her presonality.

Constructive resolving of educational problems as well as learning problems is frequently based on theoretical and practical postulates of Pedagogy, Psychology, Sociology, Andragogy and other related sciences. Creative participation of school and parents offers great possibilities and oportunity for improvement of the school and parents and their common participation help the development of democratic and human school tryaing to establish a dialogue of equality and cooperation with parents. Being partners, teachers and parents are both responsible for development and progress of a child. They both have rights and obligations connecting them and making them responsible. Values that child has accepted in his/her family are the base for any kind of upbringing and schooling. School should start from these attitudes in it educational work especially when family did not contribute or does not realize its primary educational role in adequate way. Individualized approach to the pupil and his/her family, and then systematic approach in understanding relationship within the family of each pupil or student will contribute partnership among parents and school to
be developed. Without such approach, pupil remains an isolated individual only. It is useful to know all inadequacies and advantages impacting the motivation for school/parents partnership to be developed proprely. Knowledge of inadequacies and adventages will guide us in choosing adequate motivation strategies successfully encouraging parents to cooperate as partners and to participate within (their) children education process. Epstein underlines: ''Partnership is built on mutual confidence and respect requesting time and patience''.

Authors: Chi Vu Mai , Anh Nguyen Tuan , My Nguyen Ha
Published: February 2025

This research investigated the correlation between herd behavior and the fear of missing out (FoMO) in Vietnam’s security market, focusing on their combined impact on investor decisions and market stability. The authors used a survey of 212 individual investors whose data were collected through a questionnaire, with responses measured on a 7-point Likert scale from March 2024 to April 2024. Additionally, the article applied Spearman’s rank correlation coefficient to assess the relationship between these two behaviors. The findings demonstrated a significant positive correlation between herd behavior and FoMO. Investors who had a tendency for FoMO were more likely to follow herd behavior, especially during volatile markets; these behaviors tend to occur together. In conclusion, the article not only emphasized the importance of controlling psychological biases to enhance market stability but also addressed these behaviors that can help minimize speculative bubbles. The results of this research have important implications for improving Vietnam’s stock market efficiency and competitiveness. By recognizing potential biases that may influence their investment decisions, investors can adopt different strategies to mitigate the impact of such biases on their financial outcomes.

The  purpose  of  the study. This research examines injury patterns, prevalence, and management in female Kabaddi athletes from North Sumatra during the PON XXI 2024 competition, addressing a gap in sports medicine regarding the physiological challenges faced by women in this contact sport. Kabaddi's lack of research on female athletes contributes to a significant deficit in understanding its physiological impact on women.
Materials and methods. The study utilized a quantitative descriptive design with 22 female national Kabaddi athletes from North Sumatra, employing structured surveys, clinical assessments, and systematic injury documentation for comprehensive athlete health evaluation. The methodology comprised pre-competition medical screenings, post-competition injury documentation, and follow-up on recovery and rehabilitation, utilizing advanced statistical methods including descriptive analysis, frequency distributions, and correlation investigations, with significance testing established at p < 0.05.
Results. Findings indicated a 100% injury rate among participants, highlighting the extreme demands of competitive Kabaddi, with the most common injuries being muscular strains (36.4%), joint sprains (27.3%), contusions (18.2%), and other soft tissue injuries (18.2%). The severity profile revealed 45.5% of injuries were mild (Grade I), 36.4% moderate (Grade II), and 18.2% severe (Grade III), with significant correlations identified between training intensity and injury occurrence (p = 0.015), body composition and injury susceptibility (p = 0.025), and age and injury risk (p = 0.042). Injury distribution showed lower limb injuries at 54.5%, upper limb injuries at 27.3%, and trunk/core injuries at 18.2%, with primary injury mechanisms including direct contact trauma (45.5%), overextension (27.3%), rapid directional change (18.2%), and repetitive stress (9.1%). Rehabilitation outcomes indicated an 86.4% recovery success rate, although a 13.6% recurring injury rate emphasized the need for comprehensive athlete management strategies.
Conclusions. This research challenges prevailing norms in sports medicine by promoting gender-specific injury prevention, personalized management, and thorough monitoring. The study offers crucial insights into the injury patterns of female Kabaddi athletes and advocates for tailored approaches to athlete health and performance. By examining the complex interactions among physiological factors, training demands, and injury mechanisms, the research establishes a comprehensive framework for enhancing athlete care, preventive measures, and long-term sustainability in high-intensity sports.
Poverty Analysis through Spiritual, Multidimensional and Monetary Material Approaches in Indonesia
Authors: Yunanto Ary , Laksana Rio Dhani , Jati Dian Purnomo
Published: February 2025

In 2023, Banyumas' poverty rate rose, with Banyumas Regency, Central Java Province ranking eighth among all regions in terms of poverty in Indonesia. Other factors, such as social, cultural, and political factors, remain in this cycle of poverty. Low levels of education are the first step toward being unable to use and develop natural resources. After that, a poor work ethic eliminates the low production. In Banyumas district's, Central Java Province impoverished neighborhood, the study was carried out. The first year will involve selecting 200 impoverished people from four subdistricts in Banyumas Regency: Cilongok, Pekuncen, Wangon, Kedungbanteng, and Rawalo. This will allow for the identification of factors that affect the area's poverty level. The multinomial logit regression approach is an analytical tool used to address the study objectives. The findings of this study demonstrate that, in the instance of the Banyumas district region covered in this article, socioeconomic determinants do not necessarily have the same impact on multidimensional poverty or monetary poverty. The significance of formal employment status is limited to financial destitution. Multidimensional poverty alone is strongly influenced by regional geography. Only monetary poverty is impacted by informal credit, and that influence is favorable.
Contribution. This research can provide a comprehensive entrepreneurship concept that can accelerate poverty reduction in Banyumas Regency.

Published: February 2025

The spending allocated to the agricultural sector in the general budget is one of the important financial policy tools responsible for developing this important sector. In light of this, this study aimed to identify the extent of development and impact of some spending policies affecting the accumulation of agricultural capital during the study period. The regression equation was used to estimate the relationship between the variables and the (Eviwes 12) program was used to analyze the data. The results showed a positive significant effect of agricultural GDP, trade openness and inflation on the accumulation of agricultural capital. It also showed a negative significant effect of the agricultural labor force and interest rates on the accumulation of capital. This study recommended the necessity of activating the agricultural sector, introducing modern technologies, using advanced machines and equipment, moving away from traditional methods in production processes, rationalizing spending operations for fear of waste and increasing spending directed to the agricultural sector as it is one of the important sectors related to the lives and livelihoods of citizens.

Abstract: Diesel particulate filter (DPF) clogging and high temperature failures are predominant issues affecting the reliability of diesel engines in the market applications. These failures, which include substrate crack and melting, can lead to a significant increment of tailpipe particulate matter (PM) emissions, even exceeding the acceptable limits. Such DPF events not only diminish the vehicle productivity but also escalate the maintenance costs. The DPF, situated downstream in the diesel engine exhaust system, is directly influenced by the health state of the upstream engine and diesel oxidation catalyst (DOC). Addressing the risks of DPF system failures is a complex systems engineering challenge. This paper employs a fault tree analysis (FTA) to identify the root causes of these failures, considering the DPF after-treatment functions, all elements affecting system performance, and key interconnections among these elements. Then the DPF reliability optimization strategies are discussed from a system optimization perspective, focusing on reducing the engine-out PM, ensuring the appropriate substrate volume and precious metal coating content for DPF clogging, improving the virtual DPF soot loading sensor accuracy, lowering the extremely uneven flow or DPF soot loading and adopting the conservative regeneration control for high temperature failures. These measures are crucial to mitigate the failure risks and ensure the reliable DPF operation. To achieve the tighter PN requirement of future regulation, additional DPF optimizations would be required. Adopting the new Cordierite material with a higher porosity, further smaller mean pore size and uniform pore size distribution are one of current developing tendencies from existing studies. The Cordierite material with membrane design would be a new developing direction for further improving of filtration efficiency and better hysteresis of DPF pressure drop, plus lower porosity and thicker wall design would get better robustness and DPF pressure drop.

Sanshou is a sport that demonstrates the actual technical movements of attack and defense. It is also one of the confrontational fighting sports. Practical attack and defense include bare-handed and weapon-based fighting. Bare-handed fighting includes Sanshou, which is what we usually call fighting in a ring, and Push Hands, which is the push hands of Tai Chi, and weapon-based fighting. Sanda sports are actual combat exercises of offense and defense that are conducted under certain conditions and with certain competition rules. That is to say, it is a step higher than the original sparring routines and is a practical exercise. Technical training is the core content of the entire Sanda training. The level of technical skills determines the quality of sports performance. Good physical fitness is the basis for mastering and improving Sanda skills. Only when athletes master the skills can they effectively give full play to their physical training level. The two are mutually dependent. Sanda basic training refers to the training of striking, throwing, attacking and defending movements. The purpose is to enable athletes to master these movements proficiently and be able to use them flexibly and freely in actual combat.
Pore Structure and Fractal Characteristics of the H Formation of the K Structure in the Eastern X Depression
Authors: Hu Chong
Published: February 2025

To address the limited understanding of the pore structure in the H reservoir of the K structure in the eastern X depression, a fractal analysis method was employed to analyze the reservoir pores. Through the integration of experimental techniques, including casting thin sections, X-ray diffraction, and mercury intrusion, the study identified the reservoir's pore types, pore-throat distribution characteristics, and fractal properties. Additionally, it explored the relationships between fractal dimensions, reservoir physical properties, pore structure parameters, and mineral compositions.The results indicate that the pore types in the reservoir of the study area are primarily primary intergranular pores, intergranular dissolution pores, and intragranular dissolution pores. The reservoir's mineral composition is dominated by quartz and feldspar, with chlorite being the most abundant among clay minerals.Based on the morphology of capillary pressure curves, the reservoir pore structures are classified into four types: Type I, Type II, Type III, and Type IV. Their storage capacity and permeability decrease sequentially, while heterogeneity gradually increases.The reservoir pores exhibit multifractal characteristics, with the pore space divided into macropores (megapores and macropores), mesopores, and micropores (micropores and nanopores). The pore structure of macropores and mesopores is superior to that of micropores. The fractal dimension is unrelated to reservoir porosity but shows good correlations with permeability, pore structure parameters, and mineral composition.This study reveals the pore size distribution characteristics of the reservoir from the perspective of multifractal theory, providing a basis for the development of the H reservoir in the K structure of the X depression in the eastern region.

Authors: Mu Bangbang , Xie Shuaishuai
Published: February 2025

Aiming at the problem of high cost of filling materials in the coal mining process, a cement-based high-water material is proposed, and cement is used as the basic cementing material for high-water materials in coal mines. The type of cement is determined by single-factor test, and the orthogonal test design is used as the dependent variable. According to the test results, the mathematical model of the water bleeding rate is obtained by using the response surface analysis method. Combined with the two-factor correlation analysis, the influence of different single factors and two factors on the water bleeding rate is determined. The factors that are more related to the water-cement ratio, fly ash content, and thickener ratio are determined. The mathematical model of strength is established by using the response surface test design with these three factors as independent variables.

Published: February 2025

Surgical site infections (SSIs) are a major cause of postoperative morbidity, prolonged hospital stays, and increased healthcare costs. Patients with diabetes mellitus are at a higher risk of developing SSIs due to impaired immune responses and delayed wound healing. Understanding the impact of diabetes on SSIs in elective surgeries is crucial for improving perioperative care and patient outcomes. Objective: To compare the incidence of surgical site infections (SSIs) between diabetic and non-diabetic patients undergoing elective surgeries in a surgical unit and to evaluate associated factors influencing infection rates. Methods: This comparative cross-sectional study included 70 patients aged 25 years and above, divided equally into two groups: 35 diabetic patients (Group A) and 35 non-diabetic patients (Group B). The patients underwent elective, open and laparoscopy surgeries with similar perioperative care protocols, including standardised antibiotic prophylaxis. SSIs were identified based on clinical criteria, including purulent discharge, erythema, swelling, fever, and elevated white blood cell counts. Patients were followed for 30 days postoperatively to record infection outcomes. Results: The incidence of SSIs was notably higher in diabetic patients, with 42.9% (n=15) developing infections, compared to 17.1% (n=6) in non-diabetic patients (p<0.05). Demographic characteristics, including age and BMI, were comparable between the two groups. Comorbidities such as obesity and hypertension were more prevalent in diabetic patients, potentially contributing to the increased risk of SSIs. Among the surgical approaches, laparoscopic procedures were more common in both groups, yet the infection rates remained disproportionately higher in the diabetic cohort. Conclusion: Diabetes is a significant independent risk factor for SSIs, even in elective surgical procedures. The findings underscore the need for optimised glycemic control, management of comorbid conditions, and stringent perioperative infection prevention measures to improve surgical outcomes in diabetic patients.
Comparison of Urban and Rural Education in China -- A Case Study of Hunan Province
Authors: Shen Zeyan
Published: February 2025

In recent years, society attaches more importance to rural education, exposing more rural education defects to people's vision, and the disequilibrium of development between countryside and city has become a hot topic. This paper takes Hunan Province as an example to study this unbalanced development. It starts with comparing the status in quo of citys and countrysides development and specifically compares the hardware facilities and teachers. It is learned that rural education lags far behind the city in these two aspects. It can also be seen from these small aspects, that although there are policies to help the countryside, rural education still lags behind the city. Further analysis is made of the four reasons that cause the disparity of their education level, namely, economy, cognitive level, registered permanent residence and faculty: the government invests less money in rural education, parents and students in rural areas have lower cognitive level and less information is obtained, registered permanent residence hurts rural students, and rural faculty is weak; Given these reasons for the backwardness of education in countryside, specific suggestions are given, hoping to provide some reference and value for the balance of urban and rural education.

Published: February 2025

With the development of the technology, more and more affairs are gradually replaced by artificial intelligence (AI), and a large-scale AI comes into peoples lives, it not only refreshes the existence of artificial intelligence but also the number of people who use it increasing. In fact, a labor force, such as teachers, will not be replaced by AI, but at the same time it is can not be ignored that advantages are brought by AI. This paper focuses on the in-depth discussion on the work content, findings and plans during a class on the application of AI in pedagogy. Based on the development of the science and technology innovation ability and artificial intelligence, online teaching is a well-known way of learning in this contemporary society in addition to offline teaching. For teachers, teaching methods are becoming diversified; for students, it is quite significant for them to find out which learning styles they are keen on. This paper analyzes the pros and cons from the opinions of not only teachers but also students, and elaborates on the practice of AI in teaching specifically. For instance, educators are worried about the poor distraction in class of kids; also, for the young generation, they are exploring a new way of teaching that is network teaching. As for the practice, this paper refers to the class preparation, class and after class for teachers.

For Motor Imagery (MI) signals based on Brain-Computer Interface (BCI), user intentions are transformed into signals with specific frequencies that reflect motor identities. However, it is difficult to classify MI-EEG signals due to their non-stationarity and low signal-to-noise ratio. In this study, we proposed a signal preprocessing method based on the Short-Time Fourier Transform (STFT), which has high time and frequency resolution to extract detailed information from the signals. Furthermore, we constructed a hybrid model that combines our custom-designed Double-Dimensional Multi-Scale Convolutional Neural Network (DDMSCNN) with an Attention Network. Our model captures deeper spatial-temporal features and effectively manages locally significant information in MI-EEG signals. The dataset BCI Competition IV 2a is used in the experiments. The mean accuracy of user-independent classification reaches 64.04%, while user-dependent classification accuracy achieves 70.50%, which demonstrates the advantages of our hybrid DDMSCNN-Attention model. In summary, this method for MI-EEG classification has reached high accuracy while maintaining low computation time. An in-depth exploration of our model architecture may provide a fresh approach for refining the classification of MI-EEG signals, thereby advancing the field of brain-computer interactions.
Impact of Mechanical Keyboard Switch Types on Typing Performance and User Experience
Authors: Fu Wenkai
Published: February 2025

In recent years, mechanical keyboards have become the most widely used human-machine interface in public spaces, owing to their user-friendly operation, durability, simplicity, and cost-effectiveness. These keyboards, known for their tactile and auditory feedback, are often evaluated based on their performance and user preferences. This study investigates the effects of different mechanical keyboard switchesspecifically blue, red, and brownon typing performance, user experience, and perceived comfort. Data were collected through controlled experiments where participants were asked to perform typing tasks on keyboards with each switch type. The main tools used for analysis were performance metrics such as typing speed (words per minute, WPM), accuracy, and subjective user feedback gathered through surveys. The results indicate that users demonstrated higher typing speed and accuracy on the red switch compared to the blue and brown switches. Additionally, the blue switch was associated with greater tactile feedback, but at the cost of a louder sound profile. These findings suggest that switch choice significantly impacts typing performance and user experience, with implications for product design and future research in the area of human-computer interaction.

A História do Holocausto relacionada à educação em direitos humanos nas séries iniciais do Ensino Fundamental
Authors: Falavinha Ramos Luzilete , Asinelli-Luz Araci
Published: February 2025

O presente artigo tem por objetivo apresentar uma investigação realizada com seis professoras que atuam nas séries iniciais do Ensino Fundamental de uma unidade escolar da Rede Municipal de Ensino de Curitiba e que fizeram uso de recortes da História do Holocausto como tema gerador na Educação em Direitos Humanos (EDH) entre os anos de 2010 e 2019. Na tentativa de entender como se deu a escolha pelo tema holocausto e como tais práticas pedagógicas se desenvolveram, esta pesquisa de caráter qualitativo, exploratório e descritivo utilizou como instrumentos de coleta de dados entrevistas e grupo focal. Além disso, os relatórios, contendo as atividades realizadas dentro do projeto de EDH, enviados anualmente pela escola à Secretaria Municipal de Educação foram utilizados para verificar informações coletadas a partir dos instrumentos citados anteriormente. O tratamento dos dados foi feito a partir dos Núcleos de Significação (Aguiar; Ozzela, 2006) que permitiram compreender, a partir da perspectiva das professoras participantes, o processo de consolidação da EDH na unidade escolar. Os resultados apontam para uma reformulação da compreensão do que é a EDH pelas professoras participantes a partir do momento em que se envolveram com a História do Holocausto e passaram a utilizá-la como tema gerador para o desenvolvimento de práticas pedagógicas.
