“…In this type of research, in addition to assessing the evolution in the number of accidents and the possible impact of the measures taken on such accidents, differences in the accident rate related to individual variables such as age or type of contract are examined. Regarding age, higher rates of accidents have been found at the extremes of the age range (in young people due to greater carelessness and in elderly people due to a possible loss of mental-physical conditions) (Balderrama et al 2015). With regard to the type of contract, the loss ratio has been associated with precarious work and contractual instability (Benach et al 2014;Romero Caraballo 2019;Simões et al 2019).…”

Purpose The main goal was to identify the variables (sociodemographic, work, psychosocial, perceived health, and personality) associated with occupational accidents suffered in the past by women in the cleaning sector. Methods A sample of 455 women was evaluated. Results A total of 23.5% of the workers (n = 107) had suffered an occupational accident with medical leave. In general, women who had suffered some accident in their life had a worse situation in all areas evaluated. Two subsamples of women had a greater association with accidents. Specifically, the presence of work accidents was 15.9 times higher among those who presented a worse perception of their physical effort and a greater tendency towards risky behaviours and 13.5 times higher among those who had a moderate perception of physical exertion and a disability. Conclusion In general, the characteristics of female workers were found to be associated with different accident rates. Preventive actions should be designed individually.

THE PROBLEM SOLVING METHODOLOGY: AN EXPERIENCE FOR THE STUDY OF CHEMICAL BONDS. This article presents an experience of the use of the Problem Solving (PR) methodology with undergraduate students of the Licentiate Course in Chemistry of UFRGS, for the study of Ionic Bonding (LI). Salar de Uyuni salts were used to contextualize the problems employed. The Field Log records of the researchers and the presentations of the undergraduates show that the implemented didactic sequence favored conceptual learning, such as the relation between chemical bond theories and some properties of the materials, procedural learning, such as public argument, as reading and handling of different bibliographical reference sources and attitude learning, such as interpersonal relations among students and teachers during the different problem solving stages. Additionally, the results brought to evidence that, from the Problem Solving experience with the Ionic Bond contents, the future teachers were able to perceive work alternatives for their future classrooms.Keywords: problem solving; teacher formation; chemical bonds; Salar de Uyuni. INTRODUÇÃOO presente artigo apresenta uma experiência da utilização da metodologia de Resolução de Problemas (RP) com licenciandos do curso de Licenciatura em Química da UFRGS, para o estudo de ligações químicas, especificamente, Ligações Iônicas (LI). Esse conteúdo foi escolhido, pois há um pequeno número de relatos na literatura sobre o ensino de ligações químicas a partir de perspectivas investigativas. Além disso, esse tema é importante para o entendimento de outros conteúdos de química e de propriedades da matéria como condutividade elétrica, solubilidade e pontos de fusão e ebulição. 1,2De acordo com alguns pesquisadores, devido às dificuldades de compreensão dos conceitos científicos, e, também, falta de domínio do uso de metodologias alternativas ao modelo de ensino tradicional, os professores de Ciências podem afastar seus alunos do mundo científico, pois exigem que os estudantes aprendam pela memorização e não pelo entendimento dos conceitos.3-5 Essas práticas podem estar relacionadas às fragilidades na formação inicial, no que se refere à falta de um eixo formativo que possua a função de integrar conhecimentos conceituais da Química às contemporâneas metodologias de ensino.6-8 Herreid 9 destaca que dentre os professores, os de Ciências, Química e Física são os que menos empregam metodologias ativas de aprendizagem.Nesse âmbito, acredita-se que trabalhar a RP com os licenciandos no papel de alunos pode favorecer que estes se utilizem dessa metodologia nas suas futuras salas de aula com maior propriedade, como apresenta-se no decorrer do texto. FUNDAMENTAÇÃO TEÓRICA Resolução de problemasDiversos relatos na literatura apontam que o uso da metodologia de Resolução de Problemas (RP) no ensino de Química, tanto nos contextos de sala de aula, 10-13 como nos cursos de formação de professores, 14-16 contribui significativamente para a aprendizagem dos estudantes, por envolver alunos e professores na con...

“…Moreover, there is the constant ageing of the population. Age, which is increasingly greater among female workers, is related to an increase in absenteeism related to work accidents and greater severity in those cases where risks are involved (22)(23)(24)(25)(26).…”

BACKGROUND: Cleaning is considered a female-dominant occupation. Women cleaning workers present a high risk of suffering impaired health probably as a result of performing low-skilled tasks. However, to date, no studies have been found that examine the health status of female cleaning workers in Spain. OBJECTIVES: The objectives were to 1) determine the level of perceived health in a sample of female cleaning workers, 2) evaluate the main psychosocial risks they face, 3) explore the relationship between perceived health and psychosocial risk factors, and 4) compare the perceived health of those women who present some psychosocial risk factor and those who do not. METHODS: This is a multi-centered cross-sectional study carried out in the service sector of a Spanish company. The final sample was composed of 455 female cleaning workers. Sociodemographic variables, perceived health status and psychosocial risk factors were assessed. RESULTS: Women presented a high perception of health status. The main psychosocial risk was lack of acknowledgement by their superiors, which affected 25.2% (n = 111) of the sample. Moderate negative correlations (r=–.222 to –.442; p < .01) were identified between perceived health and evident psychosocial risks. Those women who presented some psychosocial risk (n = 174; 38.3%) had a worse state of perceived health in all variables studied. CONCLUSION: Presence of psychosocial risk had a relationship with a worse health perception. This article highlights the need to orient preventive actions in the psychosocial field. The COVID-19 pandemic represents a new situation to renew the health promotion between cleaning workers.
