RESUMEN El trabajo a través de aplicaciones móviles surgió como una alternativa para muchos hombres brasileños durante la crisis económica y el aumento del desempleo. Sin embargo, estos trabajadores operan de manera informal, sin relación laboral, lo que genera precariedad laboral y falta de derechos laborales. Desde un abordaje teórico-reflexivo, este artículo analiza la intersección entre la salud ocupacional, la plataformización del trabajo y los desafíos específicos que enfrentan los hombres repartidores de aplicaciones, especialmente durante la pandemia de covid-19. Las categorías reflexivas se dividieron en dos secciones temáticas: “La inserción laboral a través de aplicaciones móviles en Brasil y el modelo de trabajo mediante algoritmos” y “hombres, salud y motocicletas: la salud ocupacional y el comportamiento masculino en el trabajo a través de aplicaciones de entrega”. Se examina la expansión de este tipo de trabajo en el contexto socioeconómico brasileño, la falta de seguridad y protección laboral para estos trabajadores, así como los riesgos enfrentados, especialmente durante la pandemia, en el marco de una cultura masculina.

ABSTRACT Work through mobile applications emerged as an alternative for many Brazilian men during the economic crisis and rising unemployment. However, these workers operate informally, without a formal employment relationship, leading to labor precariousness and a lack of workers’ rights. Using a theoretical-reflexive, this study analyzes the intersection between occupational health, the platformization of work, and the specific challenges faced by male delivery app workers, especially during the COVID-19 pandemic. Reflective categories are divided into two thematic sections: “Labor insertion through mobile applications in Brazil and the algorithmic work model” and “men, health, and motorcycles: occupational health and male behavior in app-based delivery work.” The study examines the expansion of this type of work in the Brazilian socio-economic context, the lack of security and labor protection for these workers, as well as the risks faced, particularly during the pandemic, within a male-centric culture.

Eight petroleum samples from Potiguar Basin were submitted for determination of saturated biomarkers by gas chromatography (fingerprint), liquid chromatography (saturates, aromatics, resins and asphaltenes), gas chromatography-mass spectrometry (GC-MS), nickel and vanadium by high resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GF AAS). The geochemical parameters provided information on type of depositional paleoenvironment in which organic matter that gave rise to each oil sample and level of thermal maturation reached by generating rocks that make up the Potiguar Basin were deposited. The relationships between the stable isotopes of carbon (δ13C) and between Ni and V concentrations of each petroleum sample were also evaluated. The evaluations separated for oil samples into two distinct groups. Group 1 formed by samples P1, P2, P5 and P8, with characteristics of generating rock that was deposited in a marine hypersaline environment. Group 2 composed of samples P3, P4, P6 and P7 with freshwater lacustrine depositional paleoenvironment, which were elucidated through the geochemical parameters studied. The hierarchical cluster analysis was presented as promising chemometric tool for characterization of petroleum samples in the according to their origin of the generating rock by ratio parameters of hopane/sterane , tetracyclic polyiprenoids/diastereomers and diastereos R+S/cholestane R+S.

OBJETIVO: Descrever o perfil dos cuidadores de idoso, bem como sua importância e principais dificuldades no ato de cuidar do idoso. METODOLOGIA: Trata-se de estudo transversal descritivo e exploratório realizado pela equipe PET Saúde, em uma Estratégia de Saúde da Família (ESF), no município de Ananindeua, Pará. A coleta de dados foi feita por meio de um questionário semiestruturado abordando aspectos sociodemográficos e questões referentes a importância e dificuldades encontradas pelos cuidadores de idosos. RESULTADOS: Foram entrevistados 31 cuidadores, predominando sexo feminino, estado civil casado, com ensino médio completo, renda entre dois e três salários mínimos, tempo de exercício da função maior que 12 meses, em sua abrangência cuidadores informais e com vínculo de parentesco com o idoso. Os cuidadores reconheceram que é importante a presença de um cuidador e consideraram o idoso sob seu cuidado como saudável. CONCLUSÃO: A maioria dos cuidadores era do tipo informal, caracterizada por mulheres, com vínculo familiar, que destacaram a paciência e a falta de conhecimento como as principais dificuldades do cuidador. Os dados deste estudo se limitam a uma realidade local, necessitando de mais pesquisas para fomentar as particularidades e dificuldades enfrentadas pelos cuidadores.

OBJECTIVE: To describe the profile of caregivers of elderly, as well as their importance and main difficulties in caring for the elderly. METHODOLOGY: This was a descriptive, exploratory cross-sectional study conducted by the PET Saúde staff in a Family Health Strategy (FHS) in the city of Ananindeua, state of Pará, Brazil. Data was collected through a semistructured questionnaire addressing sociodemographic and issues concerning the importance and difficulties encountered by caregivers of the elderly. RESULTS: We interviewed 31 caregivers, predominantly female, married state, with complete secondary education, income between two and three minimum wages, time of exercise of the function over 12 months, most of them informal caregivers and with family relationship with elderly. Caregivers acknowledged the importance of a caregiver and found the elderly under their care as healthy. CONCLUSIONS: Most caregivers were informal type, characterized by women with family ties, which emphasized patience and lack of knowledge as the main difficulties of the caregiver. Data from this study are limited to a local reality, requiring further research to foster the particularities and difficulties faced by caregivers.
