TJ-SP case law regarding freedom of speech on the internet and the protection of online privacy (2014-2023)
No full textA colisão entre direitos fundamentais é uma barreira enfrentada por juristas trivialmente no âmbito processual. No âmbito do livro digital (e-book), observou-se que há grande repercussão midiática quando esses direitos contrapostos são a liberdade de expressão, de um lado, e os direitos de personalidade, de outro. De 2014 a 2023, foram detectadas 61 apelações cíveis que abarcam tal temática no Tribunal de Justiça do Estado de São Paulo (TJ-SP). Desse montante, 23 processos foram analisados por este Trabalho de Conclusão de Curso, com o objetivo de compreender como a Corte estadual enfrenta o dilema liberdade de expressão versus personalidade e se existe um modus operandi que guia o julgamento desses casos no TJ-SP. Em síntese, a conclusão a que se chegou foi que a Corte privilegiou o direito à liberdade de expressão, em um rigoroso placar de 12 a 11.The collision between fundamental rights is a barrier trivially faced by the legal profession in the procedural sphere. In the context of the e-book, it was observed that there is a great deal of media repercussion when these opposing rights are freedom of speech, on the one hand, and personality rights, on the other. From 2014 to 2023, 61 civil appeals covering this issue were detected in the São Paulo State Court of Justice (TJ-SP). Of this amount, 23 cases were analyzed by this Graduate Research Paper, with the goal of understanding how the state court faces the dilemma of freedom of speech versus personality and whether there is a modus operandi that guides the judgment of these cases in the TJ-SP. In summary, the conclusion reached was that the Court favored the right to freedom of speech, in a strict 12-11 score

In Brazil and worldwide, regional research has progressed, emphasizing the identification of fishery by-products, conservation of gonads, somatic cells, and tissues, consolidating biobanks as an essential tool in combating animal trafficking, especially in regions of high biodiversity. Implementation proposals, such as regionalized material collection at CETAS and the creation of a national animal identification bank, should be explored. Despite limitations, the potential for expansion and application of biobanks in monitoring illegal trade is promising, particularly with the ongoing improvement of current research
Synthesis of hematite (α-Fe2O3) nanoparticles using Syzygium cumini extract: Photodegradation of norfloxacin and enhanced recyclability
No full textIn this study, we report obtaining α-Fe2O3 nanoparticles by a green synthesis method using different concentrations of Syzygium cumini (L.) Skeels (Myrtaceae) leaf extract. X-ray diffraction (XRD) analysis of materials confirmed the presence of pure hematite phase α-Fe2O3 without any impurities. In addition, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques revealed almost spherical NPs' morphology. At the same time, it was clear from the dispersive energy X-ray (EDS) technique that no other chemical elements were present in the sample. On the other hand, the band gap energy obtained from the materials was 1.9 and 2.0 eV. The photodegradation tests showed a photocatalytic efficiency of 96 % for the sample produced with the lowest extract concentration. The mineralization rate of norfloxacin was 32.5 %, as indicated by the Total Organic Carbon tests. In addition, its potential to generate reactive oxygen species that aid in the degradation of the pharmaceutical contaminant has been confirmed.Centro de Desenvolvimento de Materiais FuncionaisFundação de Amparo à Pesquisa e ao Desenvolvimento Científico e Tecnológico do MaranhãoSchool of Materials Engineering, Purdue UniversityConselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)PPGQ – Federal Institute of Maranhão Campus São Luís Monte Castelo – (IFMA), MACDMF LIEC – Federal University of São Carlos – (UFSCar), SPPDQ – Federal Institute of Maranhão Campus São Luís Monte Castelo – (IFMA), MAPPGQuim-Federal University of Maranhão-(UFMA), MAIQ – São Paulo State University (UNESP), SPIQSC – University of São Paulo (IQSC-USP), SPIFSC – University of São Paulo (IFSC-USP), SPIQ – São Paulo State University (UNESP), SPCNPq: 116926/2022-8FAPESP: 2013/07296-2FAPESP: 2018/09761-8FAPESP: 2018/22022-0FAPESP: 2018/22210-0FAPESP: 2018/22211-7FAPESP: 2019/06650-3FAPESP: 2021/06128-5FAPESP: 2022/06219-3FAPESP: 2022/12895-1FAPESP: 2023/01425-7FAPESP: 2023/06558-5FAPESP: 2023/07525-3CAPES: 88887.472618/2019–00CAPES: 88887.626035/2021-0
Effect on mechanical and microbiological properties of adding calcium glycerophosphate and xylitol to glass ionomer cement
No full textThis study aimed to evaluate the effect on the mechanical and microbiological properties of incorporating calcium glycerophosphate (CaGP) and/or xylitol into resin modified glass ionomer cement (RMGIC). Six experimental cements were tested: i) RMGIC without additions; and RMGIC with ii) 5% xylitol; iii) 10% xylitol; iv) 3% CaGP; v) 3% CaGP and 5% xylitol, or vi) 3% CaGP and 10% xylitol. The compressive strength, diametral tensile strength and surface hardness were determined (24 h and 7 days). Antimicrobial/antibiofilm activity was evaluated. Compressive strength values after 24 h for +3% CaGP & 5% xylitol were higher and similar to RMGIC. After 7 days, +3% CaGP & 5% xylitol presented the highest compressive strength values. The +3% CaGP & 10% xylitol showed the lowest values of diametral tensile strength values (24 h). The RMGIC with +3% CaGP & 5% xylitol showed the highest diametral tensile strength (7 days). The surface hardness (24 h) were highest for the RMGIC and +10% xylitol. After 7 days, +3% CaGP & 5% xylitol showed the highest value. The +3% CaGP & 5% xylitol or +3% CaGP & 10% xylitol showed the lowest levels of microbial/biofilm formation. The addition of CaGP/xylitol promoted improved the mechanical and antibacterial properties of RMGIC.School of Dentistry University of Ribeirão Preto – UNAERP, SPDepartment of Dental Materials Endodontics and Operative Dentistry Bauru School of Dentistry University of São PauloFraunhofer Institute for Manufacturing Technology and Advanced Materials IFAMDepartment of Morphology Genetics Orthodontics and Pediatric Dentistry São Paulo State University (Unesp) School of Dentistry, SPDepartment of Preventive and Restorative Dentistry School of Dentistry São Paulo State University (UNESP), SPPolyclinic of Operative Dentistry Periodontology and Pediatric Dentistry Faculty of Medicine Carl Gustav Carus Technical University of DresdenDepartment of Morphology Genetics Orthodontics and Pediatric Dentistry São Paulo State University (Unesp) School of Dentistry, SPDepartment of Preventive and Restorative Dentistry School of Dentistry São Paulo State University (UNESP), S
Temporary Facility Location Problem in Humanitarian Logistics: A Systematic Literature Review
No full textBackground: Facility location is a key challenge in humanitarian logistics, particularly in disaster response, where rapid and efficient resource deployment is crucial. Temporary facilities offer a cost-effective solution due to their rapid deployment and flexibility in addressing increased demand and the dynamic conditions of post-disaster environments. Methods: This study conducts a systematic literature review following PRISMA guidelines to analyze facility location problems involving temporary or modular facilities in humanitarian logistics. A total of 65 articles from Scopus and Web of Science were analyzed. Results: Most studies focus on temporary facilities like shelters and medical centers in earthquake-affected areas, with most applications in Asia. Despite being temporary, only 6% of the studies consider closure decisions. Recent research explores modular facilities that enhance adaptability through module relocation and capacity adjustments. Conclusions: Temporary facilities after sudden-onset disasters require advanced modeling approaches that include multi-period planning, modular design, and complex decision-making, requiring solutions through heuristics or relaxations. However, there is a lack of research on their application in slow-onset and human-induced disasters. Moreover, considering geographical, cultural, and political factors is essential to ensure effective solutions. Further studies are also needed on facilities functioning as collection and processing centers, given their critical role in the humanitarian supply chain.Production Engineering Department Polytechnic School Universidade de São Paulo—USPProduction Engineering Department São Paulo State UniversityEnvironmental Engineering Department São Paulo State UniversityProduction Engineering Department São Paulo State UniversityEnvironmental Engineering Department São Paulo State Universit
Evaluation of 10% metronidazole and 2% lidocaine paste with ozone therapy for the treatment of osteonecrosis of the jaw induced by zoledronate after extraction in ovariectomized rats
No full textA osteonecrose dos maxilares induzida por medicamentos (MRONJ) é uma condição patológica que ainda não apresenta um consenso na literatura sobre o seu tratamento e por isso merece atenção. Visto isso, terapias secundárias podem desempenhar papel importante no controle e resposta tecidual, ao passo que, a pasta para uso tópico à base de metronidazol e o ozônio sistêmico, podem ser promissoras. O objetivo deste trabalho foi avaliar o desempenho tópico da pasta à base de metronidazol associada com ozonioterapia sistêmica no tratamento da osteonecrose dos maxilares induzidas por bifosfonato após procedimento de exodontia em ratas senis ovariectomizadas e submetidas a terapia com zoledronato. Para isso, 30 ratas, de 12 meses de idade, foram divididas em 3 grupos. O grupo de microtomografia (n=15) teve 5 ratas submetidas à eutanásia após ambientalização em biotério para análise da arquitetura óssea (MCT0), 5 receberam zoledronato por 3 semanas e foram analisadas posteriormente (MCT1), e 5 receberam solução salina para comparação (MCT2). As demais ratas foram divididas igualmente em grupos experimentais, no grupo SAL as ratas foram submetidas a aplicações de solução de cloreto de sódio 0,9% e o grupo ZOL recebeu aplicação de Zoledronato 100μg/kg, ambos a cada 3 dias durante 7 semanas; o grupo ZOl+OZ/POI, recebeu a aplicação de zoledronato seguindo o mesmo protocolo e aplicação tópica da pasta, no alvéolo após a extração do 1° molar inferior esquerdo, além de ozonioterapia sistêmica. Após o fim do período de aplicação das terapias, as ratas foram submetidas a eutanásia, as mandíbulas foram analisadas por microtomografia computadorizada e exames histológicos. Os resultados indicaram a boa resposta tecidual e um processo de neoformação óssea eficiente, apesar da indução a osteonecrose, do grupo que recebeu as terapias alternativas em comparação ao grupo ZOL que apresentou um tecido ósseo frágil, áreas de necrose e inflamação.Medication-induced osteonecrosis of the jaw (MRONJ) is a pathological condition that still lacks a consensus in the literature regarding its treatment and therefore deserves attention. Given this, secondary therapies may play an important role in tissue control and response, while topical metronidazole-based paste and systemic ozone may be promising. The aim of this study was to evaluate the performance of metronidazole-based paste associated with systemic ozone therapy in the treatment of bisphosphonate-induced osteonecrosis of the jaw after tooth extraction in ovariectomized senile rats subjected to zoledronate therapy. For this purpose, 30 12-month-old rats were divided into 3 groups. The microtomography group (n = 15) had 5 rats subjected to euthanasia after environmentalization in a vivarium for analysis of bone architecture (MCT0), 5 received zoledronate for 3 weeks and were subsequently revealed (MCT1), and 5 received saline solutions for comparison (MCT2). The remaining rats were equally divided into experimental groups; in the SAL group, the rats were subjected to applications of 0.9% sodium chloride solution and the ZOL group received application of Zoledronate 100 μg/kg, both every 3 days for 7 weeks; the ZOl+OZ/POI group received the application of zoledronate following the same protocol and topical application of the paste, in the alveolus after the release of the first lower left molar, in addition to systemic ozone therapy. After the end of the therapy application period, the rats were euthanized, and their jaws were analyzed by computed microtomography and histological examinations. The results indicated a good tissue response and an efficient process of bone neoformation, despite the induction of osteonecrosis, in the group that received alternative therapies compared to the ZOL group, which presented fragile bone tissue, areas of necrosis and inflammation.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)FAPESP: 2022/10964-
Non-modifiable and modifiable factors affecting anxiety and depressive symptoms in young athletes
No full textA presente dissertação teve como objetivo inicial conduzir uma revisão sistemática com meta análise e meta regressão para investigar a prevalência e incidência de ansiedade e depressão moderadas a graves em atletas, identificando potenciais características que influenciam esses desfechos, considerando o nível de competição (amador, universitário, elite) e o tipo de esporte (individual vs. equipe), assim como o gênero (masculino vs. feminino) e a idade dos atletas por meio de uma revisão sistemática com meta-análise e meta-regressão. Este estudo incluiu 49 estudos e demonstrou uma prevalência de 15% para sintomas moderados a graves de ansiedade, 18% para sintomas moderados a graves de depressão e 35% para sintomas moderados a graves de ansiedade/depressão entre atletas em atividade, com uma incidência de 40% para sintomas de ansiedade/depressão quando ferramentas de triagem validadas foram utilizadas. No entanto, houve uma diferença notável na prevalência quando comparadas ferramentas de triagem para depressão (18%) e aquelas baseadas em autorrelato dos atletas sobre diagnóstico médico, dados de registro ou entrevistas diagnósticas (6%). Além disso, a maior carga de ansiedade, depressão e sintomas de ansiedade/depressão foi observada em atletas amadores e envolvidos em esportes individuais. Logo, é necessário também avaliar relações causais entre os possíveis fatores de risco ao longo de suas carreiras esportivas. Nesse sentido, o segundo objetivo foi conduzir um estudo de caráter transversal no sentido de verificar a associação entre fatores não modificáveis (categorias de idade, sexo e raça/etnia) e fatores modificáveis (modalidade esportiva, condição socioeconômica, carga de treinamento, sono e transtornos alimentares) com sintomas de ansiedade e depressão em jovens atletas.
Este estudo envolveu 168 jovens atletas de modalidades coletivas e individuais e explorou os determinantes da ansiedade e depressão nesses grupos. A qualidade do sono (p < 0.001) parece assumir um papel central no fenômeno investigado, afetando ambos os desfechos de saúde. Atletas do sexo feminino (p = 0,018), com 18 anos ou mais (p = 0,049) e aqueles de modalidades esportivas individuais (p = 0,012) apresentaram sintomas depressivos mais elevados. Atletas de grupos sociais minoritários apresentaram sintomas depressivos mais elevados do que o grupo Dominante (p = 0,014). Conclui-se, portanto, que a baixa qualidade do sono parece ser uma variável potencialmente associada à maior ocorrência de sintomas de ansiedade e depressão entre atletas jovens, enquanto a prática de esportes individuais e a maior idade parecem desencadear sintomas depressivos nesses atletas.The present dissertation initially aimed to conduct a systematic review with meta-analysis and meta-regression to investigate the prevalence and incidence of moderate to severe anxiety and depression in athletes, identifying potential characteristics that influence these outcomes. It considered the level of competition (amateur, collegiate, elite) and the type of sport (individual vs. collective), as well as gender (male vs. female) and age through a systematic review with meta-analysis and meta-regression. This study included 49 studies and demonstrated a prevalence of 15% for moderate to severe anxiety symptoms, 18% for moderate to severe depressive symptoms, and 35% for moderate to severe anxiety/depressive symptoms among active athletes, with an incidence of 40% for anxiety/depressive symptoms when validated screening tools were used. However, there was a notable difference in prevalence when comparing depression screening tools (18%) with those based on athletes' self-reports of medical diagnoses, registry data, or diagnostic interviews (6%). Additionally, the highest anxiety, Depression, and Anxiety/Depression symptom burdens were observed in amateur athletes and those involved in individual sports. Therefore, it is also necessary to assess causal relationships between possible risk factors throughout their athletic careers. In this regard, the second objective was to conduct a cross-sectional study to examine the association between non-modifiable factors (age categories, sex, and ethnicity) and modifiable factors (sport type, socioeconomic status, training load, sleep, and eating disorders) with anxiety and depressive symptoms in young athletes. This study involved 168 young athletes from ambos time and individual sports and explored the determinants of anxiety and depression in these groups. Sleep quality (p < 0.001) appears to play a central role in the investigated phenomenon, affecting ambos health outcomes. Female athletes (p = 0.018), those aged 18 or older (p = 0.049), and those participating in individual sports (p = 0.012) exhibited higher depressive symptoms. Athletes from Minority Group showed higher depressive symptoms than Dominant group (p = 0.014). Thus, it is concluded that poor sleep quality appears to be a potentially associated variable with a higher occurrence of anxiety and depressive symptoms among young athletes, while participation in individual sports and older age seem to trigger depressive symptoms in these athletes.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)CAPES: 00
Fuel energy transportation and transformation based on the hydrogen obtainment system by solid-oxide fuel-cell and ethanol steam reforming integration
No full textIn operation, hydrogen transportation can be subjected to frequent issues due to the complexity of its storage containment. This work investigates the transportation of a blend of ethanol and water instead hydrogen (e.g., compressed), combined with the usage of a compacted station (ten feet container volume) operated by a Solid-Oxide Fuel-Cell (SOFC) and an Ethanol-Steam-Reformer (ESR) integrated as a system. This system aims to produce clean-hydrogen and electricity either concomitantly or alternately, directly at the final consumer location (e.g., industrial facilities or refueling stations), establishing it as a valid alternative for energy transportation of fuel, particularly addressing the complexity of hydrogen transportation. A previous energy-mass balance studied related to hydrogen/electricity obtainment, based on exactly this stationary compacted station design, is used. An exergetic analysis related to the operation of the system (SOFC and ESR combined) complements the previous study based only on energy and mass balance. The investigation focused on a simulation of 1 kg of hydrogen production, involving the addition of an electrolysis (ELE) rig. The simulations conducted demonstrated operationally optimized values for ESR temperatures. It noticed a system exergetic efficiency of 79.8 % for an ESR temperature of 660 K (387 °C). Additionally, a methodology based on Value-Analysis (VA) or Value-Engineering (VE) is applied to evaluate the ethanol–water blend's carrying features compared to compressed hydrogen transport. The value of the function ‘retain the volume/mass’ of the ethanol–water blend is 31.4 % enhanced, compared to the hydrogen gas compressed, which is precisely the main disadvantage of hydrogen carrying.Universidade Estadual PaulistaUniversidade Estadual de Campinas (UNICAMP)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Laboratory of Optimization of Energy Systems (LOSE) Department of Energy School of Engineering Institute of Bioenergy Research (IPBEN-UNESP) - Associated Laboratory of buaratinguetá Sao Paulo State University (UNESP), SPPost-graduation Program in Mechanical Engineering Federal University of ABC (UFABC)Laboratory of Optimization of Energy Systems (LOSE) Department of Energy School of Engineering Institute of Bioenergy Research (IPBEN-UNESP) - Associated Laboratory of buaratinguetá Sao Paulo State University (UNESP), SPCAPES: 33002037024P7CAPES: 913621/2023-0
Proximal tibial osteotomies for treating grade IV medial patellar luxation in two feline stifles
No full textObjectives: There is a lack of literature regarding the surgical management of high-grade patellar luxation in cats. Among the available options, corrective osteotomies are suitable for correcting severe bone deformities. Therefore, this study aimed to report on the surgical management of grade IV medial patellar luxation (MPL) through tibial corrective osteotomies in two cats. Material and Methods: The two cats were diagnosed with grade IV MPL. The marked alterations observed in radiographic and tomographic images indicated external tibial torsion of 15.7° and 21.8°, concomitant with tibial valgus of 13.9° and a tibial plateau angle (TPA) of 20°, respectively. For surgical treatment, chrondoplasty was performed in Case 1, and block recession trochleoplasty in Case 2, followed by a combination of techniques originally developed for dogs. Proximal total tibial osteotomy (PTO) was combined with medial crescentic closing wedge osteotomy (MCCWO) for one case and with cranial closing wedge ostectomy (CCWO) for the other case. Results: Satisfactory postoperative results were obtained for both cats, resulting in realignment of the stifle extensor mechanism, with both tibial torsions close to 0° in subjective analysis. Additionally, a mechanical medial proximal tibial angle of 91° and a mechanical medial distal tibial angle of 99.3° were achieved for the first cat, whereas a TPA of 9.2° was achieved for the second cat. No major complications were observed, and the cats showed an early return to weight-bearing on the affected limb. Conclusion: Both cases highlight that tibial corrective osteotomies are suitable for cats and may play a role in the decision-making process for treating high-grade MPL. Moreover, a combination of PTO with MCCWO or CCWO may help achieve satisfactory outcomes.Department of Animal Science Federal University of Parana - UFPR Palotina, Acess Road Pioneiro 2153Department of Clinical and Veterinary Surgery School of Agricultural and Veterinary Sciences “Júlio de Mesquita Filho” São Paulo State University — UNESP, Access Road Prof. Paulo Donato Castellane s/n, Jaboticabal, State of São PauloOrtopediaVet Veterinary Clinic Dr. Eloy Curuci and team, Volta Redonda Street, 670 - Campo Belo, São Paulo, State of São PauloDepartment of Clinical and Veterinary Surgery School of Agricultural and Veterinary Sciences “Júlio de Mesquita Filho” São Paulo State University — UNESP, Access Road Prof. Paulo Donato Castellane s/n, Jaboticabal, State of São Paul
The feeling of hope and emotional suffering in teens in post-pandemic times
No full textConsiderando o contexto atual e a atuação dos seres humanos como sujeitos que vivenciam, participam, intervém e atuam sobre a realidade, o trabalho ora descrito teve como ponto de partida investigar o sentimento de esperança no futuro e o sofrimento emocional a partir da escuta de 3276 1meninos e meninas adolescentes dos 7º, 8º e 9º anos das escolas de ensino fundamental (anos finais) da rede pública e privada em tempos pós-pandêmicos. Além de um procedimento ético e humanizador, político e pedagógico, a escuta deve ser pensada como uma atitude ontológica de reconhecimento dos meninos e meninas adolescentes na condição de pessoas em si mesmas, em sua igualdade e em suas diferenças em relação aos adultos, conferida pela condição peculiar de desenvolvimento, uma escuta sensível que respeite as adolescências. A partir dessas afirmações, surgiram algumas indagações: Meninos e meninas adolescentes têm manifestado o sentimento de esperança quanto ao seu futuro? Meninos e meninas adolescentes têm manifestado problemas de sofrimento emocional? Existirá uma relação entre o sentimento de esperança e o sofrimento emocional autopercebidos por meninos e meninas adolescentes? Haverá diferenças entre a manifestação desses sentimentos e as variáveis de gênero, raça e tipo de escola. Optamos pela revisão bibliográfica acerca dos descritores esperança, adolescentes e sofrimento emocional. A presente pesquisa de caráter exploratório, descritivo e com abordagem quanti- qualitativa tem por objetivos verificar se existem relações entre o sentimento de esperança e a frequência do sofrimento emocional entre adolescentes; verificar se existem relações entre a frequência de sofrimento emocional e o sentimento de esperança manifestados por adolescentes que autodeclaram diferentes cor/raça; verificar se existem relações entre a frequência de sofrimento emocional e o sentimento de esperança manifestados por adolescentes de diferentes gêneros; verificar se existem relações entre a frequência de sofrimento emocional e o sentimento de esperança manifestados por adolescentes de diferentes tipos de escolas - públicas e particulares e validar um instrumento de mensuração do sentimento de esperança, em tempos pós-pandêmicos. A hipótese da presente pesquisa é que quanto mais alto o escore de sofrimento emocional menor o escore de esperança e vice-versa. Com relação ao sofrimento emocional e o diálogo com as variáveis desta pesquisa, os resultados evidenciam que há problemas de sofrimento emocional em ambos os tipos de escolas, sendo a pontuação mediana para as escolas particulares ligeiramente superior à das escolas públicas e as meninas adolescentes apresentaram os maiores escores. Quanto ao sentimento de esperança, os resultados encontrados indicam que as e os adolescentes obtiveram maiores frequências de respostas em categorias individualistas, que não souberam responder e a indícios de sofrimento emocional, respectivamente, sendo a última categoria mais frequente entre as meninas. Foi possível encontrar evidências do caráter correlacional entre o sofrimento emocional e o sentimento de esperança autopercebidos pelos adolescentes confirmando-se a hipótese inicial de uma relação entre os dois constructos: adolescentes com alto escore de sofrimento emocional tiveram baixos escores de sentimento de esperança e vice-versa. Ressalta-se assim, a necessidade da convivência cuidadosa dentro dos tempos e espaços da escola para a promoção do bem-estar a si e ao outro, sobretudo assegurando a quem é de direito - os meninos e as meninas adolescentes - a esperança por um futuro melhor.Considering the current context and the role of human beings as subjects who experience, participate in, intervene in, and act upon reality, this study aimed to investigate the feeling of hope for the future and emotional distress by listening to 3,276 adolescent boys and girls from the 7th, 8th, and 9th grades of public and private middle schools in the post-pandemic period. Beyond being an ethical, humanizing, political, and pedagogical procedure, listening should be understood as an ontological attitude of recognizing adolescent boys and girls as individuals in their own right, in both their equality and differences from adults, given their unique developmental condition. This requires a sensitive approach that respects the diversity of adolescent experiences. Based on these premises, several questions emerged: Do adolescent boys and girls express a sense of hope for their future? Do adolescent boys and girls report experiencing emotional distress? Is there a relationship between the self-perceived sense of hope and emotional distress among adolescent boys and girls? Are there differences in the manifestation of these feelings based on gender, race, and type of school? We opted for a literature review on the descriptors "hope," "adolescents," and "emotional distress." This exploratory and descriptive study, with a quantitative and qualitative approach, aims to determine whether there is a relationship between the sense of hope and the frequency of
emotional distress among adolescents; assess whether there is a relationship between the frequency of emotional distress and the sense of hope among adolescents who self-identify with different racial backgrounds; examine whether there is a relationship between the frequency of emotional distress and the sense of hope among adolescents of different genders; investigate whether there is a relationship between the frequency of emotional distress and the sense of hope among adolescents from different types of schools—public and private; and validate a tool for measuring the sense of hope in the post-pandemic period. The hypothesis of this study is that the higher the emotional distress score, the lower the hope score, and vice versa. The results indicate an average emotional distress score of moderate intensity (24.62 points), with some extreme cases reaching close to 100, highlighting the need for concern regarding the well-being of adolescents experiencing distress.Considerando el contexto brasileño actual y el papel del ser humano como sujeto que experimenta, participa, interviene y actúa sobre la realidad, el trabajo aquí descrito tuvo como punto de partida investigar el sentimiento de esperanza y el sufrimiento emocional a partir de la escucha de niños y niñas adolescentes de 8º y 9º grados de escuelas primarias públicas y privadas (últimos años) en tiempos post pandémicos. Además de ser un procedimiento ético, humanizador, político y pedagógico, la escucha debe ser vista como una actitud ontológica de reconocimiento de los chicos y chicas adolescentes como personas en sí mismas, en su igualdad y en sus diferencias con los adultos, conferidas por su peculiar condición evolutiva, una escucha sensible y respetuosa de la adolescencia. A partir de estas afirmaciones, han surgido algunas preguntas: ¿han expresado los chicos y chicas adolescentes un sentimiento de esperanza en su futuro? ¿Han manifestado los chicos y chicas adolescentes problemas de angustia emocional? ¿Existe correspondencia entre el sentimiento de esperanza y el malestar emocional autopercibido entre chicos y chicas adolescentes? ¿Existen diferencias entre la manifestación de estos sentimientos y las variables de género, raza y tipo de escuela? Optamos por una revisión bibliográfica sobre los descriptores esperanza, adolescentes y malestar emocional. El objetivo de este estudio exploratorio, descriptivo y cuantitativo fue validar un instrumento de medida del sentimiento de esperanza, conocer la prevalencia de este sentimiento entre los adolescentes, comprobar si existen diferencias entre género, raza y tipo de escuela y si existe correspondencia entre el sentimiento de esperanza y el sufrimiento emocional autopercibido entre chicos y chicas adolescentes. El instrumento de investigación fue un cuestionario online que contenía ítems relacionados con el perfil, el sentimiento de esperanza y el malestar emocional y dos escalas - la primera, un cuestionario con ítems sobre el sentimiento de esperanza y la segunda, construida y validada en Brasil sobre el malestar emocional en adolescentes
