For years, pink pepper has been used in folk medicine as an analgesic and anti-inflammatory, which has aroused the interest of the scientific community regarding its biological activities, such as antioxidant. The search for natural compounds as alternatives to the use of synthetic antioxidants has been growing in the meat industry. Among meat products, processed chicken products have a great need to use these additives, as they have a high susceptibility to the development of lipid oxidation. This study aimed to evaluate the effect of pink pepper extract and the type of packaging (aerobic and vacuum) on the physicochemical characteristics and oxidative stability of chicken burgers. Pink pepper ethanol extracts were obtained and analyzed for total phenolic compounds and antioxidant activity (DPPH and ABTS). Subsequently, the extracts at a concentration of 90 mg of gallic acid equivalent/kg of meat were applied to chicken hamburgers and evaluated as a natural antioxidant compared to a formulation containing synthetic antioxidant (BHT), and a control formulation (without antioxidants). All samples were stored in an aerobic environment and under vacuum for seven days at 4 °C and evaluated for oxidative stability, color and pH. The pink pepper extract showed considerable content of phenolic compounds and antioxidant activity. The hamburger with pink pepper extract was more effective than the one with BHT to delay the lipid oxidation of samples conditioned in an aerobic environment and was as efficient as this synthetic antioxidant in samples packed under vacuum. Regarding the samples packaged in an aerobic environment, pink pepper proved to be as efficient as BHT after 7 days of storage. There was a slight reduction in pH of the samples packed in an aerobic environment and darkening of the samples with the addition of pink pepper extract, probably due to the slightly acidic pH and the coloring of the natural extract. The application of pink pepper extract as a natural antioxidant is efficient to delay lipid oxidation, showing that it can be used as a promising natural antioxidant in the industry.
Profissionalização docente na educação infantil no município de São Carlos - SP: a sobreposição da lógica educacional à lógica assistencialista
(Universidade Federal de São Carlos, 2022-08-18) Bueno, Jaqueline Cristina dos Santos; Filho, Alceu Gomes Alves; https://lattes.cnpq.br/7885557554922569; https://orcid.org/0000-0002-7465-1581; Candido, Silvio Eduardo Alvarez; https://lattes.cnpq.br/0194644249955417; https://orcid.org/0000-0002-5275-6577; https://lattes.cnpq.br/8283279518927940
The present study addresses organizational change with a focus on the transition from welfare to educational logic in early childhood schools in the city of São Carlos, using a survey on the training and specialization of the teaching staff to analyze this process. Data obtained from the Municipality of São Carlos and interviews with teachers from the municipal early childhood education network were used for this purpose. Faced with social changes related to the way of seeing the child as a social actor, theories began to value the experiences and experiences of this age group, and this had an impact on education. Initially, daycare centers were designed with a more assistentialist character, supervised by the Social Assistance Department, with a focus solely on the care and hygiene of children. Professionals who worked directly with students did not need any training, since early childhood education was not part of basic education . Since the 1990s, several laws have brought about changes in child care. This required an adjustment on the part of professionals and managers of the teaching organization. A process of encouraging the continuing education of professionals working in education was initiated. Thus modifying the routine, the assessment methods, and consequently the skills developed. It was noted that the vast majority of professionals had their level of education increased during their professional lives and continuing education is something present in the school calendar. It can be concluded, therefore, that even when caring is associated with educating in early childhood education, the assistentialist logic of the day care center has been gradually replaced by the educational logic, and it is possible to verify an overlap between the two logics at times through the perspectives and modes thinking, as well as everyday attitudes already established in the organization's routine.
Formigas (Hymenoptera: Formicidae) e vespas parasitoides (Hymenoptera: Braconidae) em duas fitofisionomias de Cerrado
(Universidade Federal de São Carlos, 2022-08-18) Iéck, Bianca da Cruz; Schlindwein, Marcelo Nivert; https://lattes.cnpq.br/9690898537150950; Dias, Angélica Maria Penteado Martins; https://lattes.cnpq.br/8637344058859147; https://lattes.cnpq.br/0983737147439182
Environments with diversified vegetation in phytophysiognomies, such as the Cerrado, provide high species diversity. In the state of Minas Gerais, the cerrado occurs predominantly and has important conservation units to preserve the fauna and flora of this biome, with Serra da Canastra National Park (PNSC) standing out. Despite its extension and importance, studies on the biodiversity present in the park, especially on invertebrates, are still scarce. Thus, the present work aimed to know the fauna of ants and parasitoid wasps collected with Moericke traps in phytophysiognomies of rupestrian fields and gallery forest in Serra da Canastra National Park, MG, Brazil. For this, we used data collected monthly, from December 2018 to October 2019 at three collection points, each point represented by two adjacent areas: one of rocky field and one of gallery forest. A 50m transect was drawn in each area with 100 Moericke traps distributed, which were exposed for 48 hours. Data on parasitoid wasps were obtained at the subfamily level; ants were identified in morphospecies. A total of 11,143 ant specimens were collected, grouped into 96 morphospecies, belonging to 31 genera of 7 subfamilies, with 5,287 individuals recorded in the rocky field and 5,856 in the gallery forest. A total of 2,857 specimens of parasitoid wasps of the Braconidae family were collected, with 87 individuals found in rupestrian fields and 2,770 in gallery forest, distributed in 18 subfamilies. The ant species richness was significantly higher in the gallery forest and the composition was different in the gallery forest when compared to the rupestrian field. For parasitoid wasps there was a greater abundance of individuals in the gallery forest and a greater richness of subfamilies in the campo rupestre. This result can be explained by the vegetation structure, because in the gallery forest the number of diversified plant species forms a heterogeneous and complex environment, providing greater availability of food resources and nesting sites, allowing the occurrence of nests and the coexistence of a greater number of species. Considering that plant diversity can influence herbivore populations, the presence of endemic plants in the rupestrian fields may be able to harbor differentiated hosts of specialized parasitoid wasps. The results obtained in this work demonstrate that the Serra da Canastra National Park harbors a very rich fauna of ants and parasitoid wasps, with a high diversity of species, especially when considering the gallery forest. These results can be expanded from other studies to be carried out in the park area.

(Universidade Federal de São Carlos, 2022-08-18) Gonçalves, Simone Munafó Tostes; Santos Junior, João Batista dos; https://lattes.cnpq.br/5615071332323472; https://lattes.cnpq.br/8213048231177175
This work addresses aspects of teacher training through a collaborative process that is configured from the Classroom Study approach. The study took place during the COVID-19 pandemic with 13 elementary school teachers from a public school in the city of Sorocaba/SP, in a formative process for the teaching of science of interest in the implementation of scientific literacy. Taking into account that the Classroom Study takes place in stages of development, the teachers went through a conceptualization with the theme chosen in their theoretical approach, collaboratively carried out lesson plans, applied and investigated the proposals of the contents and, finally, carried out analyzes reflective. This process proved to be effective for the development of the introductory implementation of scientific literacy where the teachers developed aspects of the collaborative culture among their peers, favoring their professional development.
Atuação dos orientadores pedagógicos dos centros de educação infantil do município de Sorocaba
(Universidade Federal de São Carlos, 2022-08-18) Galão, Sabrina Aparecida; Sant'Ana, Isabella Mendes; https://lattes.cnpq.br/7860235863062183; https://lattes.cnpq.br/0966995604985853
This study aimed to investigate the role of the Pedagogical Advisor who works in the public network in Early Childhood Education institutions in a city in the interior of São Paulo. As specific objectives were defined: 1) to know the Pedagogical Advisor's perspective regarding his/her professional role; 2) to investigate the challenges, potentialities and characteristics of the work and significant experiences about the performance in the area. The research was based on the Cultural-Historical Theory and semi-structured interviews were carried out with 5 (five) Pedagogical Advisors effective in the position for more than five years. The information obtained indicates that the participants addressed the relevance of this professional's work and presented several dimensions about their role in Early Childhood Education, covering actions aimed at planning; the teaching-learning process and the training of teachers and education assistants. Challenges highlighted include: gaps in initial training; lack of continuing education; performance in two school units and various activities that extrapolate the functions related to the Pedagogical Advisor. The potential of the work involves the configuration of a school environment more favorable to the observation of child development, based on the pedagogical strategies carried out by the teachers; the training of educators and the existence of pedagogical actions that are more integrated with school agents. Regarding the experiences, it was observed that the participants exposed important events in their professional trajectories, based on the interrelation of social, cognitive and affective aspects. It is argued that, due to the complexity that permeates the reality of the Pedagogical Advisor's performance, it is understood that it is necessary to value this and other professionals in Education, especially in Early Childhood Education, from the recognition of the work of the Pedagogical Advisor. Pedagogical Advisor, aiming at the quality of care offered to early childhood.
Arte sonora: nomadismo, escutas e processos criativos
(Universidade Federal de São Carlos, 2022-08-18) Ramos, Alex Suraty; Nespoli, Eduardo; https://lattes.cnpq.br/0482744763085170; https://lattes.cnpq.br/8414390712773145
The present work proposes to investigate the poetic aspects intrinsic to the Sound Art, taking the nomadism notion as the principal reference. Starting from the relationship between the pieces, the listening modes and the interactive processes, the dissertation approaches how the choices of materials, technologies and the formation of sound artists are important elements in the creative process. The sound artist transits between different means, knowledges, technologies and art languages to propose their own pieces. This research conducts a mapping of píeces and sound artists, tracing a broad dialogue with the investigated bibliography. The researched Sound Art pieces are found as sound installations, site-specific, sound sculptures and interactive environments. The Sound Art explores the potential of listening and the use of sound as a way of interacting with the pieces. In this way, the research points out that this artistic genre is characterized by its hybridism, revealing some historical approximations between music and the contemporary plastic arts. Furthermore, it is of great importance for the conception of Sound Art the influence of the experimental pieces of John Cage and the Fluxus group. From Cox's theory (2004; 2009) about the notions of becoming and duration, the virtual and the actual; and from Santos's theory (2000; 2004; 2006) about nomadic listening, it was concluded that Sound Art enables a listening in movement, dialoguing with the spectator’s memories on aesthetic enjoyment in sculptures, installations and architectonic spaces. So the sound artist is observed as a proposer of pieces and the creation arises from experiences in process.
Análise da concentração de elementos potencialmente tóxicos em hortaliças cultivadas de modo convencional, hidropônico e orgânico
(Universidade Federal de São Carlos, 2022-08-18) Silva, Victor Dubas da; Oliveira, Luciana Camargo de; https://lattes.cnpq.br/6238603150964753; https://lattes.cnpq.br/9107130480998070
In search of a better quality of life, it is currently common to look for organic products, which tend to be seen as healthier, one of the reasons being the possibility of them having less contaminants. Amongst the main contaminants are the potentially toxic elements (PTEs), as, for instance, cadmium, copper, chromium and lead. Motivated by the risks posed by the consumption of food contaminated with PTEs and the availability of vegetables grown by different farming methods, this study analysed the concentrations of Al, Ba, Cd, Co, Cr, Cu, Fe, K, Mn, Mo, Ni, Pb, Sr and Zn in curly and smooth lettuce, collard greens, escarole and rocket grown by conventional farming, hydroponics and organic farming, aiming to investigate possible relations between the concentrations of PTEs and the farming methods. The samples were obtained in the region of Sorocaba – SP in local commerce, and the concentrations were determined by microwave plasma atomic emission spectroscopy (MPAES). Higher concentrations of Al, Ba and Fe were observed on vegetables from conventional farming (C), when compared to those from organic farming (O), and the latter higher than those from hydroponics (H) (trend C > O > H). K, Pb and Zn showed the trend O > C; Sr: C > O = H; Mn: C > O; Mo was present in a lower concentration on vegetables from conventional farming; and for Cr and Cu no tendencies were observed. Cd, Co and Ni concentrations were below the limit of detection in most samples and, therefore, it was not possible to find any trend for these elements. In this context, for the studied samples, it was not possible to affirm that a given farming method favours higher or lower concentrations of the analysed elements in general. However, the knowledge about PTEs concentrations on vegetables is fundamental to the monitoring of these species on the environment, as it is for the maintenance of a food quality control.
Os olhos de Ojuobá: experiências docentes para a educação das relações étnico-raciais no ensino fundamental da rede pública municipal de Sorocaba
(Universidade Federal de São Carlos, 2022-08-18) Cavalheiro, Adilene Ferreira Carvalho; Pinheiro, Rosa Aparecida; https://lattes.cnpq.br/6292207464385037; https://lattes.cnpq.br/9616524538043974
The research on screen analyses how pedagogical practices are revealed for the Education of Ethnic Racial Relations (ERER) that intend to get rid of the distancing perspective, arising from the touristic curriculum. It comes from the initial consideration that African and indigenous matrices are silenced throughout the year, becoming visible in the school environment, only on specific dates, and in a punctual mode. Scientific studies on curricular themes and anti-racist education show the insistent reproduction of knowledge that arises from Eurocentric thinking and colonialised mindsets, as choices that underlie the teaching-learning processes in the context of Basic Education, and reveal limitations in the process of continuing education of ERER teachers. In view of these findings, we elaborated the question of this research: how can pedagogical practices in the context of elementary education in public municipal schools of Sorocaba converge with the Education of Ethnic-Racial Emancipatory Relations? The scope of this research resides in the elementary school grounds, second stage of Primary School Education, in two public municipal Educational Institutions of the city of Sorocaba, which caters for children from the 1st to the 9th grade, and adheres to the Institutional Initiation Scholarship Program to Teaching – PIBID, whose chosen theme was “Education of Ethnic-Racial Relations and Human Rights”. This is a qualitative research, with a methodological approach that took place through a narrative interview and bibliographic review on studies that focus on ethnic-racial identification and teacher training. We seek to start our journey from the perception and perspectives of the teachers participating in the research on their formative experiences, articulated with pedagogical practices that invited the African matrix to become the focus of their attention. “The eyes of Ojuobá...” is a title that refers to choosing a type of register that dialogues at the same time with the theoretical-methodological framework and allows a sensitive hearing, to listen and build with teachers the data about the perceptions arising from the knowledge of experience confluent with the ERER. The results indicated the existence of pedagogical practices that brought the African matrix as their central focus. An incipient process, constructed in the border territory between school and university, however, a powerful contribution to the strengthening of afro-perspectivist approaches in a sustainable way within the school. The possible articulations convey considerations about the training processes for ERER, creatively empowered at the crossroads between the personal and the professional dimension.
Interrupções e distrações na assistência de enfermagem na Unidade de Terapia Intensiva-COVID-19 em um hospital universitário
(Universidade Federal de São Carlos, 2022-08-18) Fonseca, Renata Elizabete Pagotti da; Zem-Mascarenhas, Silvia Helena; https://lattes.cnpq.br/0185144417072417; https://lattes.cnpq.br/2371913920864364
Frequent disruptions, whether from interruptions or distractions, negatively impact health care, impairing the cognitive process. When a task is interrupted, when resuming, the professional needs time to return to the point where he stopped, and it is possible that some steps of the process are omitted or repeated and, consequently, can lead to errors. In view of this theme, we chose to study interruptions and distractions during the activities carried out by the nursing team in an ICU for the care of patients with COVID-19 and reflect on strategies to reduce these interruptions and distractions. The objective of was to analyze the interruptions and distractions witnessed by nurses and nursing technicians, as well as the perception of these professionals on this topic. The development of the research took place in three phases. In phase I, a literature review was carried out, to list the main interruptions and distractions experienced by the nursing team in the literature and the strategies to minimize them. In phase II, on-site observations were carried out and in phase III, the interview with the nursing team was carried out. The theoretical framework used was patient safety. Data analysis in phase I was performed with a structured instrument, in phase II it was performed through absolute and percentage frequencies and through measures such as mean, standard deviation, minimum, median and maximum, Poisson regression model and regression model Gamma. For all analyses, a significance level of 5% was adopted. Finally, in phase III, the analysis took place through Bardin's content analysis. As a result, of the 243 activities performed by the team, 61 of them suffered interruptions (25.1%) and 8 of them suffered distractions (3.29%). The most interrupted activities were the administrative ones, such as annotation in the electronic system, printing of labels for the collection of exams and in carrying out the systematization of nursing care. However, it was observed that there were interruptions in care activities, such as when a new patient was admitted to hospital, when checking the prescription and in the preparation and administration of medication. The main source of interruption identified was the nursing technician, followed by equipment, self-interruption and the nurse. There were activities performed by the nursing team that interrupted other collaborators, such as, for example, pronation and supination, intercurrences during the shift and attire, as well as activities performed by the nursing team that were interrupted, such as taking notes. As distractions, cell phone use, parallel conversations and equipment alarms were signaled. It is concluded that interruptions can lead to consequences such as errors in medication preparation and administration, stress, delay and physical and emotional overload, and strategies to avoid interruptions and distractions in the work environment are considered important. This study was innovative in carrying out observations within an ICU for the care of patients with COVID-19, to collect data on interruptions and distractions to reflect on strategies to ensure that work is carried out safely.
