Students and graduates of Agronomy at the Federal Institute of Santa Catarina (IFSC) - Campus São Miguel do Oeste joined this case study. The research aimed to characterize the profile of academics and correlate the training trajectory with professional insertion. The emphasis is on the family farming succession process among those from rural units. In methodological terms, the data collection took place through closed questionnaires. The target audience was 61 students and 36 graduates. Data analysis shows that 63.9% of respondents come from rural families. Others 28.8% have no parental connections with agriculture. The geographical origin of the graduates/students is in municipalities located within a radius of 60 km from São Miguel do Oeste. Desires regarding the course are similar among groups with different backgrounds, with many uncertainties persisting on the future. Changes of mind about the desired professional occupation are usual during the course year. After graduating, while waiting for job opportunities, many assume temporary jobs which differ from their aspirations. Among those from rural areas, the search for improving the family property and continuing as a farmer stands out, with one out of two graduates aiming to manage the family businesses.

This article aims to propose educational technology tools in different types of content presentation, which propose practices and methods such as interactivity, availability, accessibility, memorization, visualization and synthesis. The method is established by surveying bibliographical material which produces reports of experiences with these technologies, and which are the corresponding platforms or applications. The development presents these technologies, produces an analysis of its potentials and limitations and uses the experiences with educational technologies in other areas of study as comparison, enlightening the suitability of these tools for the complementarity of the study in the Technical Course in Forests. The conclusion is the verification of the positive effect produced by the use of these technologies accompanied by a critical review of their uses.

Sistema de gerenciamento de energia para baterias li-íon aplicadas em veículos elétricos

Traditional vehicles powered by internal combustion use fossil fuels derived from petroleum, which is a non-renewable source of energy, releasing polluting gases into the atmosphere capable of interfering with climate change and contributing to an increase in the average temperature of the planet. A solution to minimize the emission of pollutants is the use of purely electric traction vehicles, which require energy storage systems that are increasingly adequate and efficient. In this context, the main objective of this work is to analyze and implement an energy storage system, thus aiming to define the most efficient type for applications in a low-cost purely electric traction vehicle. It was observed that Li-ion (Lithium Ion) batteries are currently the most suitable for this type of application, however, they require a dedicated control to provide the best performance, useful life and safety guarantee. In this way, a BMS (Battery Management System) circuit was developed, responsible for managing the charging and discharging processes, balancing between series of the battery packs. The BMS implemented proved to be adequate, being able to guarantee the satisfactory operation of the storage system.

Análise das personagens do Romance "Carrie, a estranha"

This article aims to analyze the characters in the 1974 horror novel “Carrie”, by Stephen King, taking into consideration the theories present in the elements of the narrative and considering literature as a science that must be proven in detail by us, as Portuguese language teachers. The theoretical assumptions that allowed this analysis were Gancho (2003) and Cândido (1976) as well as Stephen King’s book itself. The analysis showed that a story is much more than what is on the printed paper, it is interpretative and each character is important in making the narrative a tangle of choices, actions and consequences.

Relações ambientais, sociais e econômicas do uso do canudo de plástico

Wed, 23 Apr 2025 00:00:00 +0000

Discussions regarding the use of plastic and its consequences stimulate the search for alternative materials, such as bioplastic, produced from renewable sources. One of the single-use plastic products, used on a large scale, and also by People with Disabilities – PwD, is the straw. The use of straws, mainly due to their environmental impacts, is the subject of legal regulations for their restriction and banning, however for a portion of society that depends on this product for their survival, as is the case of many PwD, these regulations are exclusionary. In this context of socio-environmental debates, and considering that a portion of society is dependent on straws, the work set out to raise and compare, through a literature review, the advantages and limitations of the use of plastic straws by PwD, taking into account environmental, social and economic aspects. For its execution, a systematic bibliographic review was carried out followed by a comparative analysis. The results show that the production of bioplastic straws can be as polluting as conventional plastic straws, as well as their disposal; despite being a dispensable item for most people, for some PwD it is an essential item that cannot be eliminated from the market; The costs to produce a conventional plastic straw are lower than alternatives. Therefore, it cannot be concluded that bioplastic straws are a favorable solution for both the environment and PwD; new materials need to be developed so that they can be accessible, sustainable and inclusive.

O GÊNERO DA QUÍMICA

Leila Violin — Thu, 12 Jun 2025 00:00:00 +0000

This article presents the experience report of a project developed in a technical high school class in chemistry in 2019, "The gender of chemistry", in which a didactic sequence was used that aimed to provide, in addition to learning chemistry, more specifically on the topic of radioactivity, a reflection on the representation of gender in science. The results are presented through the discourses of the students participating in the project, collected from (self) evaluative questionnaires and it was possible to evaluate the results in terms of significant learning, the difficulties encountered, the contextualization of knowledge through the adoption of interdisciplinarity, their reflections about women's issues in the sciences and the historical erasure of women chemists, as well as how much the chemical knowledge of radioactivity was appropriated by them and the positions that were possible as a result of this appropriation. The research showed that the inter and transdisciplinary pedagogical proposal of the project allowed the students to feel they were the subjects of the learning process and contributed to their better understanding and position in relation to the reality that surrounds them and to radioactivity. Likewise, it was possible to verify the importance of addressing the gender issue with science, contributing to social discussions in the area.

Entrevista – Diálogos Acadêmicos: reflexões sobre plágio em tempos de inteligência artificial

Elton Paulo Dobrovoliski , Jesué Graciliano da Silva, Eli Lopes da Silva — Thu, 12 Jun 2025 00:00:00 +0000

The university educational model has transformed over the last few decades. One aspect is the expansion of the applicability of artificial intelligence (AI) in pedagogical and teaching practices. In parallel to this, the phenomenon of academic productivism values performance based on quantitative criteria of technical-scientific publications. These aspects converge into one theme, the production of scholarly texts. In this scenario, AI of the generative category is presented, classified as a disruptive technology that is capable of creating texts from the processing of information existing on the internet. Despite the intrinsic benefits of the tool, the educational sphere has been reflecting on the possible negative impacts related to scientific integrity and academic misconduct, in part due to the failure to develop a critical sense in the practice of writing when using the tool, especially the commission of plagiarism. Considering that educational institutions are spaces with potential for critical reflection, the eighth edition of the live “Academic Dialogues” welcomed two guests, Jesué Graciliano da Silva, and Eli Lopes da Silva, to discuss the ethical use of AI in the production practices of academic texts and how plagiarism touches on this issue. The lecture is an initiative of the Publications Coordination (PROPPI) and the IFSC Editorial Board. It was broadcast on the IFSC YouTube channel, on August 14, 2024.
