Iron is an important ion that regulates many metabolic functions in the human body, and its deficiency or overload can cause serious health problems. In view of this, the development of tools that can quantify iron in aqueous media is quite valuable. A new material based on a metal-organic framework (MOF) and a calixarene derivative (CALIX), here named CALIX@UiO-66-NH2, was successfully prepared and used as a luminescent sensor for iron ions in a water matrix containing various metal ions. The post-synthetic modification was demonstrated to be efficient on the MOF (UiO-66-NH2) modification, leading to a hybrid platform. The effect of the combination of both components (MOF and CALIX) led to a platform more sensitive to iron detection than the independent compounds. The CALIX@UiO-66-NH2 sensor shows a linear response toward Fe3+ ions with satisfactory linearity (R2 = 0.994) within the concentration range of 6.74 × 10−6−1.72 × 10−5 mol L−1. The limit of detection was determined to be as low as 1.6 mg L−1. The data demonstrate that CALIX@UiO-66-NH2 is an excellent probe for detecting Fe3+, as confirmed by almost complete fluorescence suppression. body problems this valuable metalorganic organic CALIX, CALIX , (CALIX) CALIX@UiO66NH2, CALIXUiO66NH2 CALIXUiONH CALIX@UiO 66 NH2, UiO NH2 NH postsynthetic post synthetic UiO66NH2 UiONH (UiO-66-NH2 compounds CALIX@UiO66NH2 CALIX@UiO-66-NH Fe3 Fe R2 R (R 0.994 0994 0 994 674 6 74 6.7 106172 10 1 72 10−6−1.7 105 5 10− L1 L L−1 16 1. suppression (CALIX CALIXUiO CALIXUiO66NH UiO66NH (UiO-66-NH CALIX@UiO66NH 0.99 099 99 67 7 6. 10617 10−6−1.

Abstract The Galapagos Islands, a natural heritage of humanity, have meticulous control of wildlife and strict inspection of the number and frequency of visitors. The increase in tourists, apart from positive aspects, and the increase in population generates a greater demand for electrical energy. In this sense, Galapagos seeks a boost to comprehensive energy sustainability, replacing thermal energy with environmentally friendly Non-Conventional Renewable Energy (NCRE), through the optimal energy management project through the Conolophus microgrid project. This document analyzes the optimal management of electrical energy (short-term economic dispatch) considering the stochasticity presented by the high insertion of NCRE in the Santa Cruz-Baltra electrical system. For it. The free simulation software called “SimSEE” (Electric Energy Systems Simulator) is used, where operational scenarios are modeled with and without the Conolophus project in order to analyze its impact on the planning of the operation of the Santa Cruz-Baltra system.

Resumen: Las islas Galápagos, patrimonio natural de la humanidad, cuentan con un control minucioso de la vida silvestre y ejercen estricta inspección del número y frecuencia de visitantes. El incremento de turistas, aparte de aspectos positivos, y el incremento de la población genera una mayor demanda de energía eléctrica. En este sentido, Galápagos busca un impulso a la sostenibilidad energética integral, reemplazando la energía térmica con Energías Renovables No Convencionales (ERNC), amigables con el medio ambiente, a través del proyecto de gestión óptima de la energía mediante el proyecto de microrred Conolophus. En el presente documento se analiza la gestión óptima de la energía eléctrica (despacho económico de corto plazo) considerando la estocasticidad que presenta la alta inserción de ERNC en el sistema eléctrico Santa Cruz-Baltra. Para ello. se usa el software libre de simulación denominado “SimSEE” (Simulador de Sistemas de Energía Eléctrica), donde se modelan escenarios operativos con y sin el proyecto Conolophus con la finalidad de analiza su impacto en la planificación de la operación del sistema Santa Cruz-Baltra.

Abstract: The 35 sister-cities agreements of Oaxaca de Juárez and Guanajuato capital do not automatically lead into a useful paradiplomatic activity for the citizens. The specialized literature has marginalized four core components in the management of a beneficial internationalization of municipalities: visibility, functionality, rationality, and institutionalization. Through a model based on the four components, questionnaires were submitted to both municipalities through the National Transparency Platform. The end goal of such was to assess the visibility, functionality, rationality, and the institutionalization dimensions for the 35 of international sister-cities agreements signed by both Mexican municipalities. Results suggest an insufficient visibility of the sister-cities agreements, a precarious functionality, a questionable rationality in the selection of the sister-city’ agreements, and a scarce institutionalization and follow-up for most international sister-cities agreements in which both Mexican capitals take part.

Resumen: Los 35 hermanamientos internacionales de Oaxaca de Juárez y la capital de Guanajuato no conducen automáticamente a una actividad paradiplomática útil para la ciudadanía. La literatura especializada ha marginalizado cuatro componentes medulares para la conducción de una internacionalización provechosa de los municipios: la visibilidad, la funcionalidad, la racionalidad y la institucionalización. A través de un modelo que incluye los cuatro componentes, se aplicaron cuestionarios a ambos municipios a través de la Plataforma Nacional de Transparencia para evaluar la visibilidad, la funcionalidad, la racionalidad y la institucionalización de los 35 acuerdos de hermanamientos internacionales suscritos por ambos municipios. Los resultados sugieren una insuficiente visibilidad de los hermanamientos, una precaria funcionalidad, una cuestionable racionalidad en la selección de los hermanamientos y una escasa institucionalización y seguimiento de la mayoría de los hermanamientos internacionales de los que son parte estas dos capitales mexicanas.

Resumen La moderna Sociedad del Conocimiento percibe una innovadora característica basada en manejar los contenidos curriculares, potenciando el pensamiento lógico matemático por medio de plataformas y aplicaciones digitales. El objetivo del presente trabajo se centraliza en analizar estrategias didácticas aplicadas por docentes para potenciar las habilidades matemáticas en los estudiantes del nivel de Bachillerato General Unificado dentro de la Unidad Educativa “Eidan Abel Erique Cercado” del cantón San Vicente. El aspecto metodológico se basó en el enfoque mixto, empleando como instrumento primordial una prueba pedagógica que mide las destrezas del pensamiento numérico, así como los indicios de una entrevista semi estructurada y los aportes de docentes del área de matemáticas como participantes dentro de un grupo focal. Se comprobó la predisposición para un trabajo orientado bajo la plataforma Khan Academy, necesaria para beneficiar las habilidades del pensamiento numérico poco perfeccionadas en el estudiante. Finalmente, se denotaron aquellas estrategias empleadas por los docentes las cuales no afirman una estimulación consistente para potenciar las habilidades numéricas, demostradas bajo un nivel poco aceptable en el afianzamiento de la resolución de problemas con enfoque matemático en los estudiantes.

Abstract The modern knowledge society perceives an innovative characteristic based on managing curricular contents, promoting mathematical logical thinking through digital platforms and applications, the purpose of this work is focused on determining the existing perception with the use of the Khan Academy platform in the mathematical skills and how teachers focus didactic strategies to enhance mathematical skills in students of the Unified General Baccalaureate level within the "Eidan Abel Erique Cercado" Educational Unit of the San Vicente canton. The methodological aspect was based on the paradigm of the mixed approach, using as a primary instrument a pedagogical test that measures the skills of numerical thinking, as well as the indications of a semi-structured interview and the contributions of teachers in the area of mathematics as participants within a focus group. The predisposition for a work oriented under the Khan Academy platform, necessary to benefit the slightly improved numerical thinking skills in the student, was verified. Finally, those strategies used by teachers were denoted which do not affirm a perennial stimulation to enhance numerical skills, demonstrated under an unacceptable level in the consolidation of problem solving with a mathematical approach in students.

ABSTRACT Background and Objective Salvage robot assisted radical prostatectomy (sRARP) is performed for patients with biochemical or biopsy proven, localized prostate cancer recurrences after radiation or ablative therapies. Traditionally, sRARP has been avoided by lower volume surgeons due to technical demand and high complication rates. Post-radiation sRARP outcomes studies exist but remain few in number. With increasing use of whole gland and focal ablative therapies, updates on sRARP in this setting are needed. The aim of this narrative review is to provide an overview of recently reviewed studies on the oncologic outcomes, functional outcomes, and complications after post-radiation and post-ablative sRARP. Tips and tricks are provided to guide surgeons who may perform sRARP. Materials and Methods We performed a non-systematic literature search of PubMed and MEDLINE for the most relevant articles pertaining to the outlined topics from 2010-2022 without limitation on study design. Only case reports, editorial comments, letters, and manuscripts in non-English languages were excluded. Key Content and Findings Salvage robotic radical prostatectomy is performed in cases of biochemical recurrence after radiation or ablative therapies. Oncologic outcomes after sRARP are worse compared to primary surgery (pRARP) though improvements have been made with the robotic approach when compared to open salvage prostatectomy. Higher pre-sRARP PSA levels and more advanced pathologic stage portend worse oncologic outcomes. Patients meeting low-risk, EAU-biochemical recurrence criteria have improved oncologic outcomes compared to those with high-risk BCR. While complication rates in sRARP are higher compared to pRARP, Retzius sparing approaches may reduce complication rates, particularly rectal injuries. In comparison to the traditional open approach, sRARP is associated with a lower rate of bladder neck contracture. In terms of functional outcomes, potency rates after sRARP are poor and continence rates are low, though Retzius sparing approaches demonstrate acceptable recovery of urinary continence by 1 year, post-operatively. Conclusions Advances in the robotic platform and improvement in robotic experience have resulted in acceptable complication rates after sRARP. However, oncologic and functional outcomes after sRARP in both the post-radiation and post-ablation settings are worse compared to pRARP. Thus, when engaging in shared decision making with patients regarding the initial management of localized prostate cancer, patients should be educated regarding oncologic and functional outcomes and complications in the case of biochemically recurrent prostate cancer that may require sRARP.

Abstract Objective: Suicide attempt (SA) is the strongest predictive variable for completed suicide. The Department of Cauca in Colombia has an SA rate higher than the national average, but the factors are unknown. The objective was to identify the profiles of SA in children and adolescents of Cauca. Methods: Cross-sectional study, which included all SA (Event-356) records from the SIVIGILA platform in children under 18 years of age between 2016 and 2019. The authors described the variables and multiple correspondence analysis (MCA) with the Burt method, according to the completeness of the data to establish the possible SA profiles using STATA 15.1, and R. The Ethics Committee at Universidad del Cauca approved it. Results: The study found 977 SA during this period, 72.4% female, 97.1% adolescent, 74.4% mestizo, 19.3% indigenous, 45.3% resided in municipalities exposed to the armed conflict, 32.3% expressed ideation and previous attempts, and 15.5% prior attempts. The MCA included 810 SA and identified three profiles: “Classic”, which had mestizo adolescents with a history of prior SA, mental illness, or psychoactive substance use problems; “Related to the armed conflict”, which included female adolescents with a first SA and residents in municipalities exposed to the armed conflict; “Ethnic” represented by male indigenous, with housing in a rural area. Conclusion: The SA profiles found in Cauca were “Classic”, “Related to the armed conflict”, and “Ethnic”; these can be considered to implement prevention strategies from a cross-cultural, mental health, and gender perspective, with the presence of the state in the territories.

RESUMEN Introducción: la yerba mate (Ilex paraguariensis) constituye un recurso alimentario autóctono, formando parte de la tradición y cultura alimentaria del Paraguay. Sin embargo, existen pocos estudios locales sobre los hábitos de consumo y preferencias por los paraguayos. Objetivo: describir los hábitos de consumo de la yerba mate (Ilex paraguariensis) en el Departamento Central en el 2022. Metodología: estudio descriptivo, transversal, con datos primarios, realizado en el Departamento Central de Paraguay. Muestreo no probabilístico en racimos. Instrumento de elaboración propia, diseñado como encuesta digital en la plataforma Google Form® (EE.UU.). Las variables fueron agrupadas en datos demográficos, relacionados al consumo de mate, tereré y cocido, procesados en Microsoft Excel® (EE.UU.) y EPI INFO® 7.0 (EE.UU.). Resultados: participaron 207 personas, la mayoría contaban entre 18 a 40 años, sexo femenino (83,22 %, 119), solteros, universitarios. El consumo más frecuente fue mate+ tereré+ cocido (43,96 %, 91) y tereré + cocido (14,01 %, 29). Todos los encuestados percibían más de dos salarios mínimos, y eran trabajadores de tiempo completo. El 81,64 % (169) consumían tereré, 69,08 % (143) mate, 80,23 % (138) cocido. El tipo de yerba más consumido fue la “compuesta con hierbas medicinales”, con un promedio de 1,5 Litros diarios. Conclusión: las formas más consumidas son tereré, cocido y mate, el tipo de yerba es la compuesta con el agregado de hierbas medicinales. Se sugieren realizar estudios poblacionales más amplios sobre el consumo de bebidas a base de yerba mate en Paraguay, así como ampliar estudios sobre las posibles interacciones e inocuidad entre la yerba mate con hierbas medicinales.

ABSTRACT Introduction: yerba mate (Ilex paraguariensis) constitutes a native food resource, forming part of the food tradition and culture of Paraguay. However, there are few local studies on the consumption habits and preferences of Paraguayans. Objective: to describe the consumption habits of yerba mate (Ilex paraguariensis) in the Departamento Central in 2022. Methodology: descriptive, cross-sectional study, with primary data, carried out in the Departamento Central of Paraguay. Non-probability cluster sampling. Self-developed instrument, designed as a digital survey on the Google Form® platform (USA). The variables were grouped into demographic data, related to the consumption of mate, tereré and cocido, processed in Microsoft Excel® (USA) and EPI INFO® 7.0 (USA). Results: people participated was 207, the majority were between 18 and 40 years old, female (83.22 %, 119), single, university students. The most frequent consumption was mate + tereré + cooked (43.96 %, 91) and tereré + cooked (14.01 %, 29). All respondents received more than two minimum wages, and were full-time workers. 81.64 % (169) consumed tereré, 69.08 % (143) consumed mate, 80.23 % (138) cooked. The most consumed type of herb was “composed with medicinal herbs”, with an average of 1.5 Liters per day. Conclusion: the most consumed forms are tereré, cooked and mate, the type of yerba is the one composed with the addition of medicinal herbs. It is suggested to carry out larger population studies on the consumption of yerba mate-based drinks in Paraguay, as well as expand studies on the possible interactions and safety between yerba mate and medicinal herbs.

Resumen Este artículo analiza, a través de la simulación, dos sistemas de desarrollo regional en dos regiones de Chile (Antofagasta y Coquimbo), para contrastar su potencial para promover el desarrollo endógeno. Los modelos se elaboraron con la plataforma de simulación Social SocLab, la cual se basa en la teoría de los sistemas de acción organizada. El modelo se nutre de información proveniente de entrevistas con las partes interesadas, estrechamente relacionadas con la toma de decisiones en la asignación de fondos públicos para la innovación y el desarrollo productivo. Comparando los modelos con un enfoque cualitativo, los resultados muestran que el modelo descentralizado de Antofagasta tiene mayor potencia para promover el desarrollo endógeno, al permitir un alto grado de influencia y coordinación entre los actores locales y presentar un mejor estado de recursos críticos para este propósito, mientras que el modelo centralizado de Coquimbo presenta un gran dominio y autonomía de un solo actor (gobierno central) sobre otros actores locales, que de esta manera corren el riesgo de desvincularse del interés regional. Este documento es original y es pionero porque aplica con éxito una plataforma de simulación basada en una teoría social bien conocida (sistema de acción organizado) para modelar y simular dos sistemas de actores responsables del desarrollo endógeno regional, a fin de comprenderlos mejor, compararlos a la luz de algunos atributos para el desarrollo endógeno y luego elaborar algunas políticas de mejora en este sentido.

Abstract This paper analyses, through simulations, two regional development models to contrast their potential to promote endogenous development in two Chilean regions (Antofagasta and Coquimbo). The models were developed with the SocLab social simulation platform, which is based on the theory of Organized Action Systems. The models' input was generated by interviews with stakeholders closely involved in the allocation of public funds for innovation and productive development. The results show that Antofagasta's decentralised model promotes endogenous development by permitting a high degree of influence and coordination among local actors, while presenting a better state of critical resources for this purpose. For the Coquimbo region, the centralised model presents greater dominance and autonomy of a single actor (central government) over other actors who should respond to the local interest. The models were compared by using a qualitative approach. The novelty of the paper relies on the application of a simulation platform based on the Organized Action System theory to model and simulate two systems of actors responsible for regional endogenous development. The proposed approach helps to better understand and compare different development models which contribute to policy making.

RESUMO Nos últimos 30 anos, ocorreram transformações significativas nas relações de trabalho, no sindicalismo e na própria comunicação sindical no Brasil. O avanço do neoliberalismo e das plataformas online expandiu a informalidade, fragmentou as organizações da classe trabalhadora e produziu um proletariado da era digital ainda mais precarizado. Sob os efeitos do capitalismo de plataforma, os trabalhadores de aplicativos começaram a experimentar novos arranjos de resistência a partir da convergência midiática e das possibilidades de existir e lutar em ambientes digitais. Este artigo analisa as experiências de comunicação do grupo de moto-entregadores Galera da Pressão (GDP), em atividade na cidade de Natal, no Estado do Rio Grande do Norte, desde 2020. As reflexões buscaram identificar possíveis semelhanças e diferenças com a tradicional comunicação sindical, a partir da observação de uma paralisação liderada pelo coletivo, em maio de 2022, cujas ações foram registradas no Instagram do grupo.

RESUMEN En los últimos 30 años se han producido importantes transformaciones en las relaciones laborales, en el sindicalismo y en la propia comunicación sindical en Brasil. El avance del neoliberalismo y de las plataformas online ha expandido la informalidad, fragmentado las organizaciones de la clase trabajadora y producido un proletariado de la era digital aún más precario. Bajo los efectos del capitalismo de plataformas, los trabajadores de las aplicaciones han comenzado a experimentar nuevos dispositivos de resistencia basados en la convergencia mediática y en las posibilidades de existir y luchar en entornos digitales. Este artículo analiza las experiencias de comunicación del grupo de repartidores en moto Galera da Pressão (GDP), activo en la ciudad de Natal, en el estado de Rio Grande do Norte, desde 2020. Las reflexiones buscaron identificar posibles similitudes y diferencias con la comunicación sindical tradicional, a partir de la observación de una huelga protagonizada por el colectivo en mayo de 2022, cuyas acciones fueron registradas en la cuenta de Instagram del grupo.

ABSTRACT In the last 30 years, significant transformations have occurred in labor relations, unionism, and union communication itself in Brazil. The advance of neoliberalism and online platforms has expanded informality, fragmented working class organizations, and produced an even more precarious digital age proletariat. Under the effects of platform capitalism, app-based workers began to experiment with new resistance arrangements based on media convergence and the possibilities of existing and fighting in digital environments. This article analyzes the communication experiences of the group of delivery motorcyclists Galera da Pressão (GDP), which has been operating in the city of Natal, in the state of Rio Grande do Norte, since 2020. The reflections sought to identify possible similarities and differences with the traditional union communication, based on the observation of a strike led by the collective, in May 2022, whose actions were recorded on the group's Instagram.

SIGNIFICANCE: The Freshwater Biodiversity Information System (FBIS) is a powerful, open-access platform for hosting, sharing, and analysing freshwater biodiversity data for South Africa. Platform design and functionality were strongly informed by the requirements of key data end-users and decision-makers. The platform has over 790 000 occurrence records, which are freely available to data-users and are now being converted into impact through incorporation in national decision-support tools. With better data comes better decisions, and access to a data repository like FBIS means that the monitoring, management and conservation of our freshwater ecosystems can be improved, for the long-term betterment of both people and biodiversity.

Abstract This article endeavours to examine how Brazilian television has responded to technological trends in the context of media convergence within the realm of Brazilian television, with a specific focus on the streaming platform of Globo Group, the largest media conglomerate in Latin America, known as Globoplay. The central argument of this paper revolves around the various forms of engagement employed by the organisation as it seeks to adapt to the changing landscape of media. Using the case study method (Yin, 2015), this research correlates the theoretical framework with three central points aimed at discussing engagement in the era of media convergence as a foundation for television’s relationships with its advertisers, the creation of audiovisual products and projects, and, most importantly, its relationship with the contemporary audience. The analysis underscores the use of techniques such as artificial intelligence and machine learning, which aid the platform in reshaping its strategies and decision-making processes. In light of the findings and subsequent discussion, it can be inferred that the primary goal of these initiatives is to foster engagement among both its audience and advertisers.

Resumo Este artigo visa examinar como a televisão brasileira tem respondido às tendências tecnológicas no contexto da convergência mediática, com foco específico na plataforma de streaming do Grupo Globo, o maior conglomerado de média da América Latina, conhecida como Globoplay. O argumento central deste artigo gira em torno das várias formas de engajamento empregues pela organização enquanto procura adaptar-se ao cenário de constante mudança dos média. Utilizando o método de estudo de caso (Yin, 2015), esta pesquisa correlaciona o quadro teórico com três pontos centrais destinados a discutir as noções de engajamento na era da convergência dos média como base para as relações da televisão com os seus anunciantes, a criação de produtos e projetos audiovisuais e, sobretudo, a sua relação com a audiência. A análise destaca o uso de técnicas como inteligência artificial e aprendizagem automática, que ajudam a plataforma a remodelar as suas estratégias e processos de tomada de decisão. À luz dos resultados e discussão subsequentes, pode-se inferir que o objetivo principal dessas iniciativas consiste em adaptar-se ao contexto hipertelevisivo e ampliar o modo como o Grupo Globo se relaciona tanto com o seu público como com os seus anunciantes.

ABSTRACT Introduction Throughout their academic and professional careers, orchestral musicians are exposed to environments that exhibit varying levels of sound pressure, whether it be through individual work with their instrument or exposure to the sound emanating from the orchestral ensemble in which they are incorporated. Exposure to high sound levels can be potentially damaging to the instrumentalist's hearing health. Objectives Frame the risk and potential consequences associated with exposure to noise by professional orchestra musicians considering the most recent research; contextualize preventive measures described in the literature; and present a summary of preventive measures to be proposed to employers, musical teaching establishments and professional musicians. Methods Integrative literature review, using the Population, Exposure and Outcome strategy. The literature search was carried out in b-on platform and on the website of “Revista Portuguesa de Saúde Ocupacional Online”, with 20 articles being selected after applying the criteria defined in accordance with the objective of the present review, for a research period between 2013 and 2023. Results The level of daily exposure to noise by an orchestra musician can vary between 79 dB(A) and 111 dB(A), whether during individual daily practice of the instrument, rehearsals, or live concerts. The characteristics of the musical instrument played by the musician can increase the risk of consequences associated with noise, as well as variables associated with the musical piece worked on and the place where the musician will perform. Noise-induced hearing loss is one of the consequences most cited in the literature. Constructive/engineering, organizational and individual protection measures have been applied, which present advantages but also some potential disadvantages to the performance of orchestra musicians. Conclusion It is important that occupational health professionals initiate early intervention with orchestra musicians and collaborate with cultural institutions to implement individual and collective protection measures that are appropriate to the level of exposure to noise by instrumentalists.

RESUMO Introdução Ao longo da sua formação académica e carreira profissional, o músico de orquestra encontra-se exposto a ambientes com variados níveis de pressão sonora, seja no âmbito do trabalho individual com o seu instrumento, como na exposição ao som emitido pelo grupo orquestral onde se encontra inserido. A exposição a níveis sonoros elevados pode ser potencialmente prejudicial à saúde auditiva do instrumentista. Objetivos Enquadrar o risco e potenciais consequências associadas à exposição ao ruído por músicos de orquestra profissional à luz da investigação mais recente, contextualizar as medidas preventivas descritas pela literatura e apresentar uma síntese das mesmas a propor às instituições culturais, estabelecimentos de ensino musical e músicos profissionais. Metodologia Revisão integrativa da literatura, com utilização da estratégia Population, Exposure e Outcome. A pesquisa bibliográfica foi executada na plataforma b-on e no website da Revista Portuguesa de Saúde Ocupacional Online, tendo sido selecionados 20 artigos após a aplicação dos critérios definidos de acordo com o objetivo da presente revisão, para um espaço temporal de pesquisa entre 2013 e 2023. Resultados O nível de exposição diária a ruído por um músico de orquestra pode variar entre 79 dB(A) e 111 dB(A), seja durante a prática diária individual do instrumento, ensaios ou concertos ao vivo. As características do instrumento musical utilizado pelo músico pode incrementar o risco de consequências associadas ao ruído, assim como variáveis associadas à peça musical trabalhada e ao local onde o músico desempenhará a sua performance. A perda auditiva induzida pelo ruído é das consequências mais referenciadas pela literatura. Têm sido aplicadas medidas construtivas/engenharia, organizacionais e de proteção individual, as quais apresentam vantagens, mas também algumas potenciais desvantagens em relação ao desempenho. Conclusão Será relevante que os profissionais da saúde ocupacional intervenham precocemente junto dos músicos de orquestra, assim como colaborem com as instituições culturais na implementação das medidas de proteção individual e coletiva adequadas ao nível de exposição ao ruído.

Abstract: The Research Ethics Committee (CEP) has become an essential mechanism for social control in Brazilian research involving human subjects, contributing to the development of studies guided by ethical standards and to the protection of research participants. This article analyzes the performance of CEP in Western Amazonian institution, its history, operating conditions, trends, and different aspects between 2018 to 2022. The theoretical framework addresses the history of research involving human subjects, the origins and evolution of bioethics in the international context, bioethics in Brazil, and regulations on the ethical analysis of research. The data were collected through the Brazil Platform and reports from the institution's CEP. The CEP evaluated 865 research protocols, most of which were from Health Sciences. Additionally, it was observed that during 2018 to 2022 the covid-19 pandemic had a negative impact on the number of projects submitted for evaluation to the CEP. The 57% drop in the number of projects registered during 2020/2022 reveals the negative impact of this event on the execution of projects with human participants.

Resumo: Os Comitês de Ética em Pesquisa (CEPs) tornaram-se um mecanismo essencial para o controle social em pesquisas brasileiras envolvendo sujeitos humanos, contribuindo para o desenvolvimento de estudos regido por padrões éticos e para a proteção de participantes de pesquisas. Esse artigo analisa o desempenho de CEP em instituição da Amazonia Ocidental, sua história, condições operativas, tendências e diferentes aspectos entre 2018 e 2022. O enquadre teórico visa a história da pesquisa envolvendo sujeitos humanos, as origens e evolução da bioética no contexto internacional, bioética no Brasil e regulamentos de análise ética de pesquisa. Os dados foram coletados através da Plataforma Brasil e relatórios do CEP da instituição. O CEP avaliou 865 protocolos de pesquisa, a maioria deles de Ciências da Saúde. Adicionalmente, foi observado que de 2018 a 2022 a pandemia da covid-19 teve um impacto negativo no número de projetos submetidos para avaliação do CEP. A queda de 57% no número de projetos registrados em 2020/2022 revela o impacto negativo desse evento na execução de projetos com participantes humanos.
