(Universidade Federal de São Carlos, 2023-01-30) Araujo, Bruna Paes Junqueira; Santos, Maria Walburga dos; https://lattes.cnpq.br/2954227254025696; https://orcid.org/0000-0002-9304-5800; https://lattes.cnpq.br/9473808920463753; https://orcid.org/0000-0002-4666-5599
The objective of this research was to investigate to what extent the editions of the São Paulo Congress of Early Childhood Education (COPEDI), by bringing current themes in the theory-practice relationship, constitute a training space for early childhood education professionals. It is understood that teacher training, whether initial or continuing, should not be limited to the formal/university space, which, although it is essential, ends up not being enough, since teaching in early childhood education requires a broad and diversified training. In this sense, in addition to the individual dimension, teacher training demands interaction and collectivity, because it is through the interactions between daily practices and knowledge that training is constituted. For Nóvoa (1986, 2013, 2017), teacher training as training for a profession takes place in the crossing of different institutions. And precisely because it is understood that theoretical activity and "isolated" practice do not lead to the transformation of reality, COPEDI is taken as the object of study, a broad and plural space of recognized importance in the national scenario in the area of Early Childhood Education, which brings together teachers, researchers, specialists, students and other subjects interested in debates, research and propositions in relation to childhood. children and their rights and Early Childhood Education. Among the theoretical frameworks, we highlight some authors who served as a basis for the dialogue between teacher training, public policies, early childhood education, education forums and COPEDI: NÓVOA; KRAMER; MORUZZI; ROSENBERG; FARIA and PALHARES; MAUDONNET; SERRAO AND NASCIMENTO; TOMAZZETTI; SANTOS and MELLO. The qualitative research was organized in two complementary stages: a) bibliographic research that aimed to deepen and analyze the accumulated scientific knowledge on the theme of early childhood education teacher training and public policies, in addition to mapping the data around COPEDI and teacher training in the period from 1998 to 2019; b) documentary research, which focused on documents derived from COPEDIs, such as: Annals, programming notebooks, books, and other sources such as websites/online pages of each edition. For the analysis and discussion of the data, publications from the FPEI and MIEIB were taken as a parameter. From the materials studied, some categories of analysis were created. Thus, in the course of the research it was possible to notice the importance and recognition by researchers, students, teachers, of MIEIB, FPEI and COPEDI for the field of early childhood education. The themes of COPEDI are in line with what has been presented in the meetings of WG07 of ANPEd. Broadly speaking. In general terms, it is concluded that although COPEDI is not directly responsible for the training of teachers of early childhood education, it brings contributions to the training of these professionals to the extent that the community fosters debates from the academic sphere, the legal field and the daily practices of early childhood education, in addition to dialoguing with people and institutions directly responsible for initial and continuing education. The survey and analysis of the themes indicate that they arise from pressing situations in each historical, political and social context. Influenced, therefore, by demands brought about by changes in public policies regarding the organization and structuring of early childhood education. On the other hand, COPEDI still has the challenge of expanding the participation of basic education teachers. Keywords: Teacher education. São Paulo Congress of Early Childhood Education.

Design of new immobilized lipases for biotransformations in aqueous and organic media
(Universidade Federal de São Carlos, 2023-01-30) Guimarães, José Renato; Lafuente, Roberto Fernández; https://lattes.cnpq.br/9814026415075608; Tardioli, Paulo Waldir; https://lattes.cnpq.br/0808991927126468; https://lattes.cnpq.br/4550733668734212
A review of the literature covering research on the immobilization of lipases on hydrophobic supports was performed using systematic mapping (MS) concepts. The MS approach enabled the identification of gaps that led to the development of this thesis. The mineralization of lipases immobilized with metal phosphate was the main focus of the study. This strategy is an alternative to solve the nanoflowers fragility while maintaining some of the mineralization benefits. When mineralization is performed on previously immobilized enzymes, the researcher can select the support based on its mechanical resistance, avoiding the difficulties derived from the management of the small and fragile nanoflowers. Moreover, the mineralization of immobilized enzyme couples the positive effects of enzyme mineralization during nanoflowers production with the benefits of enzyme immobilization in preexisting solids. Several lipases were immobilized on octyl agarose beads via interfacial activation and modified with diverse metal phosphates. It was found that the effects of the metal phosphate modification were clearer and more positive using highly loaded biocatalyst, suggesting that enzyme crowding could facilitate some of the positive effects of enzyme mineralization. The effects depended on the nature of both enzyme and metallic phosphate. The incubation with only sodium phosphate or only metal chloride, as well as the immobilization on previously modified supports which produced significantly reduced effects. The immobilized enzyme mineralization cannot produce a tridimensional nanoflower, as the enzymes will be located on a flat planar surface, but the results suggest that the positive effects of the building of nanoflowers may be, at least partially, achieved using this solid-phase strategy. However, we cannot talk of nanoflowers, as these tridimensional structures will never be achieved. The study was later extended to the use of diverse commercial biocatalysts and Thermomyces lanuginosus lipase (TLL) immobilized on Purolite@ C18. The modifications greatly altered enzyme specificity, increasing the activity versus some substrates while decreasing the activity versus other substrates. Enantiospecificity was also drastically altered after these modifications. Regarding the enzyme stability, no significant positive effects were found; in fact, a decrease in enzyme stability was usually detected. The influence of the immobilization protocol on the effects of mineralization was investigated. The stability, activity and specificity of the biocatalysts were very different, both the differently blocked vinyl sulfone biocatalysts (VS-biocatalysts) and the glutaraldehyde biocatalysts prepared at different pH. The activity, specificity and stability effects of the mineralization strongly depended on the enzyme and on the immobilization protocol. For the same enzyme, a mineralization protocol could be negative, positive or present no effect depending on the enzyme immobilization procedure and substrate. These results highlight the great potential of mineralization of immobilized enzymes to improve their properties, as well as the great interactions that immobilization protocol and mineralization can exhibit. The combination of both methodologies greatly increases the possibilities to find a biocatalyst that can be suitable for a specific process. The mineralization of chemically or physically modified immobilized lipases is also a potent tool to improve enzyme features. The changes caused by chemical modifications with glutaraldehyde, trinitrobenzenesulfonic acid or ethylenediamine and carbodiimide, or physical coating with ionic polymers, such as polyethylenimine and dextran sulfate have, in most cases, negative effects with some substrates and positive with other ones. Furthermore, the same mineralization could present different effects on the enzyme activity, specificity or stability, depending on the previous modification performed on the enzyme, showing that these previous enzyme modifications alter the effects of the mineralization on enzyme features. In this way, the combination of chemical or physical modifications of enzymes before their mineralization increases the range of modification of features that the immobilized enzyme can experienced, enabling to enlarge the biocatalyst library. Eversa@ Transform immobilized on Purolite@ C18 was successfully applied in the esterification of purified fatty acids of the hydrolysis of degummed soybean oil for the synthesis of octyl esters. Furthermore, aiming at the application of biocatalysts in organic reactions, TLL was immobilized on Purolite@ C18 aminated and activated with vinyl sulfone. The use of different blocking agents as reaction end point (using ethylene-diamine, aspartic acid, glycine, and cysteine) greatly altered the biocatalyst functional features (activity, specificity, or stability). Furthermore, the differently blocked VS-biocatalysts showed different performances in the synthesis of fatty acid methyl esters. In general, they showed better affinity for the transesterification of polyunsaturated oils.

Infância, pandemia e luto: ampliação da rede de apoio afetiva e social de crianças por intermédio de uma intervenção psicossocial
(Universidade Federal de São Carlos, 2023-01-30) Sanches, Amanda Moro; Veloso, Milene Maria Xavier; https://lattes.cnpq.br/6105598873866312; https://orcid.org/0000-0002-1035-8968; Pessoa, Alex Sandro Gomes; https://lattes.cnpq.br/4333565964821090; https://orcid.org/0000-0002-9271-8575; https://lattes.cnpq.br/7726503468577560
This study aimed to assess the effects of a psychosocial intervention in expanding the perceived social support network of children who lost one or more loved ones as a result of the contamination by COVID-19. This is a quasi-experimental study, based on the mixed-methods approach and with a cross-sectional design. Eighteen children participated, aged between 8-11 years old (M = 10; SD = 0.82), randomly divided into Experimental Group (GEx) and Control Group (CG). The intervention took place over eight sessions and was conducted in the context of a public school. The Five Fields Map (FFM) was employed for data collection and the data obtained in the pre-test (T1) and post-test (T2) measures were evaluated through descriptive analysis and through the robust t test for truncated mean and dependent samples. The findings showed that the intervention was able to increase the perception of social support received in the Friends field, as well as increase the frequency of people mentioned in Level 1 of the FFM. In addition, the averages showed that the effect size in favor of GEx compared to CG was of moderate magnitude in the dimensions Family (δt = 0.4; p = 0.26), Institution (δt = 0.53; p = 0.07), Friends (δt = 0.41; p = 0.07), Community (δt =0.33; p = 0.45) and Total (δt =0.64; p = 0.11). The limitations of the investigation are discussed, as well as future studies are indicated, especially in relation to psychosocial intervention programs aimed at children who experience losses in disaster contexts.
Benefícios e propriedades tecnológicas em alimentos enriquecidos com farinha de batata yacon
(Universidade Federal de São Carlos, 2023-01-30) Barabba, Giovanna Guimarães; Kato Junior, Edison Tutomu; https://lattes.cnpq.br/2870505840656417
One of the most important aspects in controlling, preventing, and treatment for several diseases is food. Because of that, the interest in functional food has been increasing steadily to promote health in general. Functional food is those that when part of a diet, besides the basic nutrition functions, present physiological and metabolic function benefits to the organism, contributing towards health, life quality and disease prevention. Health research utilizing yacon and its derivatives stand out for their prebiotic potential, antioxidant activity, immune system improvements and decrease on blood glucose. Due to the nutritional and functional benefits that the yacon potato presents, its flour has been developed and used as an ingredient. The use of yacon and its derivatives in developing new food products is promising, since its functional properties are being researched and confirmed scientifically over time. It is possible to make yacon into flour, and with it, develop new products such as: breads, cakes, frozen yogurt, tilapia fishburger and others. The main objective of this study is to compile the necessary information for analysis and comparison of the use of yacon potato flour in formulations and its benefits for human health based on theoretical foundations, resulting in a literature review.
