Eu conto ou vocês contam? A comunicação interna no Campus Aracruz e sua relação com a política de comunicação do IFES
(Universidade Federal do Espírito Santo, 2024-09-26) Chimali, Kenya Cristina Locatelli de Oliveira; Setubal, Flávia Meneguelli Ribeiro; https://orcid.org/0000-0003-1667-7131; Vilela, Bruno de Almeida; Souza, Flavia Mayer dos Santos
The present work conducts a case study on internal communication at the Aracruz Campus of the Federal Institute of Espírito Santo (Ifes), aiming to analyze the alignment of this communication with the objectives established in Ifes’s Communication Policy. The research utilizes both quantitative and qualitative methods, including questionnaires and semi-structured interviews, to collect data from campus employees, encompassing administrative staff, faculty, managers, and directors. Data analysis in the quantitative phase was performed using descriptive statistics, while the qualitative phase employed content analysis techniques, based on theoretical studies on Organizational Communication, Public Communication, Internal Communication, and Communication Policy. The results indicate that, although internal communication is recognized as a strategic tool by managers, there are significant gaps, particularly regarding staff's lack of awareness about the Communication Policy and the underutilization of certain communication channels, such as the Ticketing System. Furthermore, the study identified a need for greater coordination among campuses and for updates to the Communication Policy to reflect new technologies and practices. This study contributes to communication management at Ifes, offering insights that can be applied at both the Aracruz Campus and other campuses within the institution, aiming to improve communication effectiveness, alignment with institutional goals, and support for expected outcomes.

Stroke is one of the leading causes of acquired disability worldwide, with approximately 80% of survivors living with permanent disabilities. Recovery of upper limb functionality is particularly challenging, with only about 50% of patients regaining some functional use after the event. In this context, physiotherapy and occupational therapy are essential, but robotic rehabilitation emerges as a promising alternative to enhance therapeutic outcomes. However, the effectiveness of these new therapies is directly linked to the control interfaces and strategies applied in the patient’s interaction with the robotic device. Thus, this work investigates the development and application of control strategies and interfaces in an arm exoskeleton designed for neuromotor rehabilitation of post-stroke patients. We explore different strategies using surface electromyography (sEMG) to identify the patient’s movement intention and strategies operated by the physiotherapist, applied to an upper limb exoskeleton. Additionally, a rehabilitation protocol was implemented using an interface based on assistive trajectory control. The results indicate significant improvements in rehabilitation, highlighting the efficacy of incorporating advanced robotic technologies in the neuromotor recovery process, providing a more effective and individually tailored approach to patient needs.

Avaliação da eficácia de um reator retangular, contínuo, com eletrodos em formato de chicanas no tratamento de efluentes oleosos por eletrocoagulação
(Universidade Federal do Espírito Santo, 2024-10-29) Leite, Daniela Luz; Andrade, George Ricardo Santana; https://orcid.org/0000-0002-1772-9477; Porto, Paulo Sérgio da Silva; https://orcid.org/0000-0002-6486-7813; Faria, Rochkhudson Batista de; Pinto, Luiz Antônio de Almeida
Oily waters from various industrial sectors are effluents containing millions of liters of oil-in-water (O/W) emulsions, requiring prior treatment before disposal. Research on electrocoagulation (EC) to recover oily effluents has been highlighted. Electrolysis, a non-spontaneous reaction that releases metal into the medium, decomposes the synthetic emulsion, resulting in the formation of flakes in the medium. The flakes integrated with the gas bubbles culminate in the separation of the oil and the obtaining of the treated effluent. This research explored the rectangular geometry, applied to an EC reactor, in the search for an efficient and rapid recovery of emulsified oil in water. The influence of the volumetric flow rate and the polarity inversion time in this process were evaluated. The dependent variables include turbidity, pH, aluminum (Al) concentration, residual oil content and zeta potential. The rectangular reactor was equipped with Al electrodes arranged in the form of baffles, connected by a polarity inverter, operating in continuous mode. The best results were obtained using 2.58 mL/s in the inlet flow rate and 20 s of polarity inversion time, achieving 95.62% oil removal and 97.87% turbidity removal. The highest energy efficiency was obtained using 4 mL/s and 20 s of the parameters recently mentioned, obtaining 89.86% oil removal and 95.70% turbidity removal. The zeta potential analysis showed that the EC alters the stability of the emulsion. The pH remained within the legal requirements throughout all experiments. The wear of the plates was minimal, stipulating that their reuse can be implemented. Complementary tests indicated that the use of perforated electrodes increases the efficiency of contaminant removal, as well as indicating that the reuse of electrodes for twice the time reduced the aluminum concentration at the reactor outlet. Despite this, in all experiments the amount of aluminum obtained was higher than the current standard, indicating the need to add another step in this process, in order to retain Al3+ ions.

"Deixa o professor explicar?": a coprodução de moralidade na fala-em-interação de sala de aula na modernidade recente

This research examines how participants in classroom interaction implement morally loaded actions and thereby manage a moral stance in interaction. It is known that the activity of attributing rights and responsibilities to self and others is a pervasive one in social life (Linell; Rommetveit, 1998) that is also evident in the organization of classroom participation in late modernity (Rampton, 2006). This qualitative study aims to, within the theoretical and methodological framework of Conversation Analysis, investigate when and with which resources the participants in our data make relevant a certain moral order of society and engage on collaboratively doing morality in interaction. In addition, this study aims to provide a characterization of how the interactional production of morality relates to the new communicative order of contemporary classroom talk-in-interaction (Garcez; Lopes, 2017). For instance, morally charged actions can be observed in complaints and reproaches addressed to students by teachers. However, in relation to the emerging interactional arrangement of the classroom, we seek to explain how sanctions like these also occur among the students themselves. Indeed, their actions are implemented in disadvantage or in favor of the teacher’s program of action. For accomplish our analytical purposes, we proceeded with a sequential and multimodal analysis of audiovisual data that belong to the corpora of Grupo Linguagem, Interação e Etnometodologia (GLIE), which consist of excerpts of naturalistic interactions recorded in a public school of Grande Vitória/ES (Goulart, 2020; Mascarenhas, 2020). Among the results of the research, the following interactional patterns were observed: a) the management of moral stance in disadvantage of the main interaction (“PMDIP”); and b) the management of moral stance in favor of the main interaction (“PMPIP”). We observed that such patterns, which are illustrative of the new communicative order, have as sequential developments a discrediting action by teachers in second sequential position (PMDIP) and a ratifying one in second sequential position (PMPIP). This shows us the relevance of teachers' moral work in the classroom interaction. We also analyzed cases of non-co-production of morality in interaction, when teachers are not oriented towards carrying out this work. Therefore, the study sheds light on the interactional consequences of managing a moral stance for ongoing activities in interactions regarding the possibilities of the teachers’ moral work, which point to different ways of doing morality collaboratively in the contemporary classroom.

The central theme of this study is the composition of dialogic networks with students about the New High School (NMS). Its general objective is to set up dialogical networks with a group of students enrolled in a state school in Espírito Santo in order to understand the enunciations about the NEM in their formative processes. To this end, the specific objectives are: a) to understand the process of creating and implementing the New Secondary Education and the main guidelines that guide this policy in Brazilian education and in the Espírito Santo State Education Network, i.e. history, legal foundations and pedagogical guidelines; b) to problematize the operationalization of the New High School in the daily life of a teaching unit of the Espírito Santo State Education Network and seek to understand, through dialogical networks set up with a group of students, their understanding of the policy in question; c) to prepare, as an educational product, a notebook with the systematization of the round table discussions held with the students. As a theoretical reference, it dialogues with Paulo Freire and authors who deal with NEM. The methodology is based on qualitative and participatory research, carried out through document consultation, moments of participant observation and conversation circles with students in the third year of secondary school at a state school in Espírito Santo. As a result, the students indicated that: a) the New High School is far from meeting the needs/expectations of the working class; b) the suppression of subjects has had an incisive and negative impact on the processes of appropriation of knowledge; c) the lack of teacher training to work with the new policy favors decontextualized teaching practices; d) there are power relations within schools that disempower dialogue between students and educators; e) the aforementioned policy was designed to scrap the social right to Education for students coming from the working class. In addition, the young people say they want to continue studying, including the desire to go on to higher education, and that there is a need to re-evaluate this policy, so that it is thought of from multiple perspectives and strengthens the social right to education, as prescribed by the 1988 Federal Constitution and Law No. 9.394/96 on the Guidelines and Bases of National Education.
