A socially assistive robot as a therapeutic tool for applied behavior analysis therapy in children with autism spectrum disorder through dynamically modulated serious games
(Universidade Federal do Espírito Santo, 2024-10-07) Freitas, Éberte Valter da Silva; Bastos Filho, Teodiano Freire; https://orcid.org/0000-0002-1185-2773; Caldeira, Eliete Maria; Cuadros, Marco Antonio de Souza Leite; Valadão, Carlos Torturella; Vasquez, Luiz Fernando Guerrero
This work presents the programming/adaptation of the Socially Assistive Robot (SAR) called Mobile Autonomous Robot for Interaction with Autistics and Trisomy 21 (MARIA T21) to be able to carry out interventions, according to the Applied Behavior Analysis (ABA) therapy, applied to Children with Autism Spectrum Disorder (ASD), Serious Games (SGs), which are projected by MARIA T21, with difficulty modulation dynamics, are used as part of this therapy thus creating a motivating and facilitating effect for children and therapists. The SGs were developed in Unity 3D, using C Sharp language (C#), and modulated according to the child’s performance, eye attention level, and user’s facial emotion, being integrated into the robot through the Robot Operating System (ROS). The child-Robot Interaction (CRI) protocol followed in this research was carried out in a child’s psychotherapy room at the APAE (Association of Parents and Friends of Excepcional People for the acronym in Portuguese) of Vitoria in Espirito Santo state (Brazil), which was instrumented with four video cameras and supervised by a group of researchers. The sample consisted of 18 children with a conclusive diagnosis of ASD, 3 girls and 15 boys, aged 5 to 9 years and presence of stereotyped movements of eyes and/or hands and/or feet. The experiments were separated into three modules for which SGs or specific therapeutic dynamics were applied, namely: Cognitive Module, Physical Module and Functional Module. The first one brings together the games and dynamics applied by MARIA T21 focused on the development and improvement of cognitive learning skills, whereas the physical module brings SGs for motor evaluation and correction, that can be used for physical and postural strengthening by a physiotherapist. Finally, the functional module has applications of SGs and Occupational Therapy dynamics in order to work on the so-called Activities of Daily Living (ADLs) and encourage autonomy in those assisted. In addition to the data recorded by MARIA T21, two evaluation scales– Pediatric Evaluation of Disability Inventory Computer Adaptive Test (PEDI-CAT) and System Usability Scale (SUS)– were applied for each module, and another for the degree of acceptance of the robot in therapy by the child. The results obtained so far enable the use MARIA T21 as an ABA therapeutic tool. In addition, the SGs are capable of dynamically modulating their difficulty, providing greater user adherence and continued attention in the optimal learning zone of the ABA bibliography while carrying out the activities. The technology embedded in the robot has also enabled the identification and quantification of characteristics and parameters, such as the presence and recurrence of stereotypies and postural dysregulations, placing the robot as an innovative and promising tool to assist health professionals in the early diagnosis, conduction and follow-up of therapies.

(Universidade Federal do Espírito Santo, 2024-05-14) Periani, Hellen Bianca Araújo; Franco, Shirley Carvalhêdo; https://orcid.org/0000-0002-0027-9182; Aldabalde, Taiguara Villela; https://orcid.org/0000-0002-7710-0355; Pereira, Gleice; Zaneti Júnior, Hermes; Silva, Carlos Guardado da
The study aims to identify cultural and information mediation practices in order to formulate procedural models of these practices that can be adopted and adhered to in order to increase the degree of cooperation and accessibility between the information management units of Brazil's State Public Prosecutors' Offices. As for the specific objectives, it addresses the concepts of cultural and information mediation, with a view to supporting the model applicable to the information management units of the State Public Prosecutors' Offices; it identifies the professionals who work in the information units of the State Public Prosecutors' Offices in Brazil; it proposes an accessibility model based on the Federal Public Prosecutor's Office Network; it seeks to develop part of the model of mediation practices that aims to increase collaboration; validates the method with professionals from the Public Prosecutor's Office as to the needs and potential of information management units in becoming a Network, by collecting data through a form and interview and; analyzes the results of the data collection, presenting procedural models applicable to the reality of Public Prosecutor's Offices and capable of being applied to other public institutions. The methodological procedures are divided into: bibliographical and documentary research, field research and exploratory research. In conclusion, the results show that the mediation practices of information professionals in the Public Prosecutor's Office corroborate the practices identified in the literature, but do not match them.

Da escultura tradicional à modelagem 3D: aspectos históricos, técnicos e patrimoniais da arte pública
(Universidade Federal do Espírito Santo, 2024-10-04) Fernandes, João Victor Silva; Cirilo, Aparecido José; https://orcid.org/0000-0001-6864-3553; Mello, Júlia Almeida de; Castilho, Liliana
This dissertation investigates the relationship between techniques, the evolution of tools, and new technologies that permeate the classical and contemporary sculptural process, while exploring connections between art and cultural memory within the urban ecosystems of Espírito Santo, with an emphasis on the Centro-Oeste region. This work is rooted in the extension project "Urban Ecosystems and Culture: Between Memory, Art, and History in the Training of Basic Education Teachers in the Centro-Oeste of Espírito Santo," which, over a year, promoted various educational actions focused on preserving local history. Based on the digital recreation of monuments through 3D modeling and printing, and the adaptation of these elements into pedagogical tools, such as the thematic chessboard, the study seeks to deepen the connection between the miniatures produced and the regional cultural heritage, promoted by the practice of collecting. Moreover, the research also addresses the impact of these initiatives on the transmission of heritage values and the strengthening of regional identity, reflecting on how art, combined with objects of affection, can serve as a link between past and present, valuing the cultural diversity and collective memory of Espírito Santo.

A utilização da variação social gírias no ensino da língua inglesa na educação básica
(Universidade Federal do Espírito Santo, 2024-08-30) Nascimento, Larissa Souza; Meira, Ana Cláudia Hebling; https://orcid.org/0000-0001-8848-6903; Martins, Raisa Maria de Arruda; Santos, Kelly Barros; http://lattes.cnpq.br/
The research aimed to investigate students’ perceptions of the use of slang in the context of English language teaching and learning. The theme aimed to include linguistic variation (slang) as a teaching and learning resource, in order to analyze whether this proposal was configured in a more attractive and meaningful format from the point of view of students immersed in the subject under discussion. In this way, the literature that underpins this study concerns the theoretical-methodological assumptions of sociolinguistics as well as the context of foreign language teaching and learning. This is a qualitative investigation, which was formalized through field research. The elements were produced through a discussion group (trigged by the semi-structured interview technique) and the introduction of a pedagogical workshop. An audio recorder was used as a tool for collecting information, and the recordings were later transcribed. The analysis resulting from the processes described was carried out using the content analysis method. In view of this, it is believed that the use of slang is effective because this linguistic variation usually makes up the daily vocabulary of young people, when used in the mother tongue, while at the same time enabling affinity and interest in the foreign language under discussion, since the presence of correlations between informal expressions in the Portuguese and English languages is perceived and, therefore, results in contextualized classes that have meaning and are meaningful to learners in the context of English language classes. The analyzed results showed that the pedagogical workshop, linked to the contextualization of the process with the use of slang as a methodology in language classes, resulted in linguistic education, which dialogues with the communicational reality of the research subjects.

Reciclagem do cátodo de bateria de íons de lítio do tipo LiFePO4 (LFP) e aplicação do material reciclado como pseudocapacitor
(Universidade Federal do Espírito Santo, 2024-07-30) Querubino, Renan Bobbio; Freitas, Marcos Benedito José Geraldo de; https://orcid.org/0000-0003-1521-774X; Machado, Marta Albuquerque; Pietre, Mendelssolm Kister de
Recycling lithium-ion batteries (LIBs) is an effective method of solid waste treatment and is crucial for the recovery of scarce, high-value metals that are of great technological importance. In this work, spent LIBs from electric vehicles were recycled through hydrometallurgical and pyrometallurgical processes, utilizing both citric acid and hydrogen peroxide leaching and alkaline leaching. The exhausted cathode material was characterized using X-ray Diffraction (XRD), Raman Spectroscopy, Energy Dispersive Spectroscopy (EDS), Scanning Electron Microscopy (SEM), and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), identifying LiFePO4, Fe2O3, and FePO4 as the primary phases in its composition, along with the secondary phases Fe(OH)3 and Fe2(PO4)O. The hydrometallurgical recycling process, performed by acidic leaching of the cathode with 1.0 mol L−1 citric acid and hydrogen peroxide, showed low selectivity for the leaching of lithium and iron. In contrast, alkaline leaching proved to be more effective in recovering lithium and preserving the structural components of the material, such as LiFePO4, while not leaching iron, resulting in a more efficient separation of battery constituents. From the residue of alkaline leaching, lithium ferrite (β-LiFe5O8) was synthesized. Structural and morphological characterizations of lithium ferrite, performed by XRD, Raman Spectroscopy, and SEM, indicated the formation of a disordered crystalline phase with agglomerated grain morphology, with particles of undefined size. The electrochemical evaluation of the recycled material as a pseudocapacitor was promising. The recycled material exhibited a pseudocapacitive profile with a maximum specific capacitance of 7.6 F g−1 and capacitance retention of 82% over 250 cycles, at a charge-discharge current density of 0.7 A g−1. The pseudocapacitive profile of this material included contributions from electric double-layer charge storage and Faradaic processes. This study demonstrates the feasibility of recycling spent lithium-ion battery materials, transforming them into high-value-added materials with promising technological applications, contributing to sustainability and the circular economy.
