(Universidade Federal de São Carlos, 2024-02-28) Alves, Claudia Oliveira Fernandes; Maria Tomazzetti, Cleonice; http://lattes.cnpq.br/4821077407620769; https://orcid.org/0000-0002-1976-4604; http://lattes.cnpq.br/3307580624688880; https://orcid.org/0009-0001-1487-6463; Fernanda Vedovatto Machado, Dijnane; Toshie Irie Saito, Heloisa; http://lattes.cnpq.br/6758025601578309; http://lattes.cnpq.br/2902881020655837; https://orcid.org/0000-0002-7435-6849; https://orcid.org/0000-0003-1061-5933
This study focuses on the Projeto de Ação Especial/PEA (Special Action Project) and aims to investigate its contribution to the continuing in-service training of kindergarten teachers in the city of São Paulo. The main objective of this investigation is to understand how the training actions developed by the PEA are carried out in the continuing in-service training at the Centro de Educação Infantil/CEI Girassol (Girassol Early Childhood Education Center). The choice and delimitation of the theme is based on the researcher’s experiences in teaching in Early Childhood Education at different moments in her teaching career, and which permeates the construction of her own conception of what it means to be a teacher, especially from her work in the Municipal Education Network of São Paulo as a teacher and pedagogical coordinator. This work methodology guiding is based on a qualitative approach, using the case study method (YIN). In order to collect the data, we used instruments such as a field diary, official documents from São Paulo Rede Municipal de Educação/RME (Municipal Education Network), CEI Girassol Pedagogical Political Project, documents and records that organize the educational unit’s continuing in-service training, as well as semi-structured interviews with five teachers and the pedagogical coordinator, participating at the PEA training. The main contributions to the theoretical framework that underpins this research include authors such as Nóvoa (1995, 2002, 2009, 2014, 2019), Tardif (2014), Zeichner (2008) Gatti (2011), Placco (2010) and others. The choice of these authors is based on their contributions that help to broaden the understanding of the conceptions that underpin the debate on continuing teacher training, especially those that shed light on the discussions about continuing in-service training in early childhood education. This study is expected to contribute to the construction of a new approach to the continuing education of kindergarten teachers in the city of São Paulo, based on official regulations, such as the Portaria nº 901, from January 24th, 2014, and the Instrução Normativa nº 14, from March 4th, 2022, which have established the Projeto de Ação Especial/PEA (Special Action Project) as an instrument for continuing in-service training. The results and discussions, based on the guiding question, point to reflections on the Projeto de Ação Especial/PEA (Special Action Project) as an important instrument that contributes to the continuing in-service training of kindergarten teachers in the city of São Paulo. Therefore, there is an understanding that the dimension of the work of continuing education and in-service training based on the PEA revealed itself as the expression of the priorities outlined by the guidelines established by Portaria nº 901, in alignment with the Political-Pedagogical Project of the Educational Unit and the curricular guidelines for Early Childhood Education, without, however, forgetting the increase in the levels of quality of care for children aged zero to three at CEI Girassol.

This study investigated the level of development of empathic active listening skills among public servants at the Center for Exact Sciences and Technology of the Federal University of São Carlos (CCET/UFSCar). Empathic active listening is a form of listening motivated by the desire to understand others through active engagement, mindfulness, and empathic comprehension. Techniques associated with empathic active listening skills contribute to improved interpersonal communication, making it a required skill for all public servants. In this context, this study aimed to measure the development of empathic active listening skills among public servants at the Center for Exact Sciences and Technology of UFSCar. To answer the research question and understand the measurement of empathic active listening, an integrative literature review was conducted to identify scales for measuring this skill. This study used the Empathic Active Listening Scale (AELS), a selfreport scale comprising three dimensions: detection, processing, and response, along with the listening skills subscale and the opportunity for conversation from the Active Listening Attitude Scale (ALAS). Data were analyzed using exploratory factor analysis. Statistical analysis of the data showed that the CCET/UFSCar presents a moderate level of empathic active listening skills and that the associations between faculty and administrative staff, and between Engineering and Exact Sciences, show the same level of development. The results of this study demonstrated the importance of empathic active listening in the development of interpersonal communication among public servants and the importance of providing training for the development of empathic active listening in the public service. This study contributed to the literature by studying empathic active listening skills among public servants at a Center for Exact Sciences and Technology of a federal university, filling an academic gap. From a practical standpoint, this research presents an empirical diagnosis of the level of development of empathetic active listening skills among public servants. As a technological product, this study developed a conclusive technical report demonstrating the level of development of public servants at CCET/UFSCar.
Desenvolvimento de sensores eletroquímicos para diagnóstico de infecção fúngicas
(Universidade Federal de São Carlos, 2025-09-26) Gallo Junior, Pedro Luis; Faria, Ronaldo Censi; http://lattes.cnpq.br/8659496864305621; https://lattes.cnpq.br/4883696230088968; Cunha, Anderson; Lindino, Cleber; http://lattes.cnpq.br/0329741640375661; http://lattes.cnpq.br/5882513103054906
DEVELOPMENT OF ELECTROCHEMICAL SENSORS FOR THE DIAGNOSIS OF FUNGAL INFECTIONS. Fungal infections, such as those caused by Candida albicans, Aspergillus fumigatus, Pneumocystis jirovecii, and Cryptococcus neoformans, are responsible for millions of deaths each year, especially in tropical and subtropical regions. The global increase in the number of immunocompromised individuals, including cancer patients, transplant recipients, people living with HIV/AIDS, and ICU patients, has significantly expanded the population vulnerable to these infections. Early diagnosis, however, remains a clinical challenge due to the lack of specific signs and symptoms in the initial stages, making laboratory methods essential to reducing morbidity and mortality. Conventional techniques such as optical microscopy, histopathology, fungal culture, and PCR often need to be combined to achieve high accuracy. In this context, this work proposes the development of an electrochemical magneto-immunoassay for the detection of fungi in human serum samples. Anti-chito-oligomer antibodies, provided by FIOCRUZ-Manguinhos, were used as specific bioreceptors for chitin, a structural component of the fungal cell wall. These antibodies were immobilized onto magnetic particles (Ab/MPs) for selective capture and onto gold nanoparticles (Ab/AuNPs) for signal amplification. The developed platform aims to provide a sensitive, rapid, and adaptable alternative for point-of-care diagnosis, especially in resource-limited settings.

(Universidade Federal de São Carlos, 2025-11-17) Gonçalves, Manoela de Araújo; Corrêa, Daniel de Souza; http://lattes.cnpq.br/0461451015026948; Sousa, Cristina Paiva de; http://lattes.cnpq.br/9002619114161319; http://lattes.cnpq.br/6939556889711360; Sousa, Cristina Paiva de; Paris, Elaine Cristina; Bernardi, Adilson César Abreu; http://lattes.cnpq.br/9002619114161319; http://lattes.cnpq.br/8475640212486290; http://lattes.cnpq.br/5280956129788239
Bacterial infections represent a widely recognized health problem and can be triggered by superficial or deep skin lesions. This scenario, combined with the growing number of cases of bacterial resistance, has intensified interest in research into new antimicrobials, both as complementary options and as more efficient forms of administration.Anacardium humile,A plant native to the Brazilian Cerrado and used in the food, cosmetic, and pharmaceutical industries, it has potential as a source of bioactive metabolites. The microorganisms that inhabit the internal tissues of plants stand out as a promising alternative to the excessive use of antibiotics, as they act in the biological control of phytopathogens and produce metabolites of biotechnological interest. Furthermore, submicron fiber mats have proven relevant in the development of dressings, as they enable the slow release of drugs due to their large surface area and high porosity. In this context, the present study aimed to evaluate the endophytic microbial diversity isolated fromAnacardium humile,with emphasis on its biological control potentialin vitro and in the characterization of enzymes produced by these microorganisms, that act as producers of secondary metabolites, evaluating their physiological and morphotintorial characteristics and their antagonic functions.Of the 65 bacterial isolates, amylase (73.8%), cellulase (43%), lipase (3%) and esterase (3%) enzymatic activities were observed, however, only 4 isolates obtained relevant inhibition halos, but only 2 isolates were identified that presented positive results for the 3 clinical strains.E. coli, S. aureus, and C. albicans. The 16S rDNA gene of 2 endophytic bacteria isolated fromAnacardium humilewas sequenced for taxonomic identification purposes. Molecular analysis revealed the presence of 2 bacterial species, namelyBacillus subtilisandBacillus amyloliquefaciensThese bacterial species were subjected to a growth curve characterization test to evaluate the best fermentation period for the endophytic microorganisms. The endophytic metabolic extracts were combined with basil, limonene, and clove essential oils, complementing the antagonistic action against strains ofE. coli, S. aureus and C.albicans and subsequently incorporated into polymeric fiber webs produced by solution blow spinning. The incorporation of lyophilized metabolic extracts ofB. amyloliquefaciens and B. subtilisassociated with essential oils in fiber sheets of the commercial biopolymer Ecovio F2332, were produced using the solution blow spinning (SBS) technique. Although the sheets presented a smaller inhibition zone when compared to the metabolic extracts associated with essential oils, their use was necessary because the extracts presented cytotoxic results, which was not observed in the spun polymer sheets, indicating the potential of these platforms for further studies for applications in skin dressings

(Universidade Federal de São Carlos, 2025-11-25) Freitas Junior , José Arnaldo de; Silva , Edson Luiz; http://lattes.cnpq.br/9720274214573371; https://orcid.org/0000-0003-3194-4912; http://lattes.cnpq.br/4055806383178293; https://orcid.org/0000-0003-3191-211X; Rodrigues, José Alberto Domingues; Zaiat, Marcelo; http://lattes.cnpq.br/2400983698111640; http://lattes.cnpq.br/7593950695805418
The increasing production of biodiesel in Brazil has generated significant volumes of crude glycerol, a low-value byproduct with potential environmental liability. In this context, wnaerobic digestion emerges as a promising alternative for the energetic valorization of these residues. This study evaluated the anaerobic codigestion of glycerol and synthetic domestic wastewater in anaerobic sequential batch fluidized bed reactors (AnSBFBRs), investigating organic matter removal efficiency, cosubstrate conversion, methane generation, and removal of emerging micropollutants. Two reactors were operated with different support materials (sand – AnSBFBR/A and shredded tire – AnSBFBR/P), varying cycle time, feeding mode, and organic loading rate. Operational parameters (pH, alkalinity, volatile acids) and the removal of seven micropollutants—caffeine, ibuprofen, diclofenac, atenolol, propranolol, sucralose, and carbamazepine—were monitored. Under intermediate operational conditions, both reactors maintained high organic matter removal efficiencies, above 75% during the first five phases, reaching maximum values of 91.7% for AnSBFBR/A (Phase 3: CT – 8 h; B – 15 min; 0.5 gCOD·L-1) and 96% for AnSBFBR/P (Phase 2: CT – 8 h; FB – 3 h; 0.5 gCOD·L-1). The addition of glycerol as a cosubstrate favored methane production (44.91% and 53.69% in AnSBFBR/A and AnSBFBR/P, respectively) but also intensified acidogenesis. From Phase 6 (CT – 8 h; 0.7 gCOD·L-1) onward, a progressive accumulation of volatile fatty acids (VFA) was observed, leading in Phase 8 (highest glycerol load applied, 1.5 gCOD·L-1) to a decrease in COD removal efficiency (74.4% in AnSBFBR/A and 64.7% in AnSBFBR/P), an increase in VFA concentrations (≈48 mg·L-1 in AnSBFBR/A and ≈45.8 mg·L-1 in AnSBFBR/P), and a reduction in pH (6.90 in AnSBFBR/A and 6.80 in AnSBFBR/P), indicating acidification and organic overload that inhibited methanogenic activity. Regarding micropollutant removal, compounds such as caffeine, atenolol, propranolol, and sucralose showed the highest removal rates, especially in AnSBFBR/P, which achieved up to 98.2% removal for caffeine and 90.9% for atenolol. In contrast, recalcitrant pharmaceuticals such as diclofenac and carbamazepine exhibited modest or even negative removal efficiencies, indicating persistence in the medium and the need for complementary technologies for their mitigation. The results demonstrate that the AnSBFBR configuration is a promising alternative for treating wastewater containing emerging micropollutants, combining high organic matter removal, efficient cosubstrate conversion, and renewable biogas generation. This study contributes to advancing the understanding of micropollutant behavior in anaerobic fluidized bed systems and provides insights for operational optimization aimed at improving wastewater treatment efficiency.
