RESUMO Objetivo Avaliar a prevalência de insatisfação com a imagem corporal e os fatores associados entre universitários da área da saúde. Métodos Trata-se de um estudo descritivo, de caráter transversal e abordagem quantitativa, com 364 acadêmicos matriculados em cinco cursos da área da saúde. Para a obtenção dos dados, foram utilizados seis instrumentos autoaplicáveis: questionário socioeconômico, demográfico e de hábitos de vida adaptado do Vigitel, o Body Shape Questionnaire (BSQ), o Eating Attitudes Test (EAT-26), o Questionário Internacional de Atividade Física (IPAQ), o Inventário de Ansiedade de Beck (BAI) e o Inventário de Depressão de Beck (BDI). Foram coletadas, ainda, as medidas antropométricas. A associação entre as variáveis estudadas e a insatisfação com a imagem corporal foi verificada por análise bivariada seguida de regressão logística, com variância robusta. Resultados Houve prevalência de insatisfação com a imagem corporal de 9,1% entre os universitários. As variáveis que, após análise múltipla, se mostraram associadas a maior prevalência de insatisfação com a imagem corporal foram: cor da pele não branca, realização de tratamento para perder peso, presença de atitudes para transtorno alimentar, estado de saúde regular/ruim, ansiedade moderada/grave e circunferência abdominal. Conclusão A prevalência com a insatisfação com a imagem corporal nos universitários foi baixa, entretanto fatores sociodemográficos, estilo de vida, estado de saúde e condições clínicas e antropométricas mostraram-se associados com a prevalência da insatisfação com a imagem corporal.

This paper investigates how gamification in the workplace has developed from 2016 to 2023 in the production sector and what ethical safeguards have been adopted. The paper presents a state-of-the-art Systematic Literature Review (SRL) performed in the Scopus and Web of Science databases to identify empirical studies involving the adoption of gamification solutions in the manufacturing and construction industries. Twenty-three articles were found and examined regarding the problems evidenced in each workplace, the methodological perspective, the gamification elements considered, the reported psychological and organizational impacts, and the ethical aspects of the research. The SRL highlighted two research gaps: the lack of ethical discussion around the gamification of workplaces and the lack of gamification applications in the construction industry. Only four studies mention ethical issues concerning the participants, and only four studies are related to construction. On the other hand, there is a tendency to use collaborative platforms to share knowledge and increase engagement.

This research combines technical, environmental, and economic aspects regarding the utilization of Bege Bahia marble waste (BB) in clinker production. Three different eco-friendly clinkers were produced, investigated, and compared with one that is commercially available. BB was used to replace 49.2%, 77%, and 80.3% of the limestone by total amount of clinker. Two clinkers were selected to produce cement pastes, and their impact on compressive strength at 28 days was examined. The results suggest that substituting limestone with BB does not adversely affect the compressive strength of cement paste. Moreover, employing 77% or 80.3% BB in clinker production does not significantly influence the alite and belite contents but slightly increases the tricalcium aluminate and ferrite phases while reducing the periclase content. A life cycle analysis was conducted to assess the effects of replacing limestone with marble waste. The results revealed a substantial decrease in abiotic depletion, leading to conservation of substantial natural resources. Consequently, the utilization of BB in clinker production makes a significant contribution to environmental preservation while providing an effective alternative to limestone. In addition, the resulting clinkers serve as useful repositories, providing a permanent and sustainable destination for waste that is currently deposited in landfills. Finally, the economic viability was also examined under various scenarios based on the distance between marble and cement plants. The results highlight the transport distance of marble waste as the primary determinant of economic feasibility in utilizing this residue as a limestone replacement.

Objective: The objective of this study is to evaluate the use of synchronous online focus groups for requirements gathering in the development of a computational tool that integrates Building Information Modeling (BIM) and Life Cycle Assessment (LCA) in hydro-sanitary building system projects. Theoretical Framework The theoretical framework is based on the integration of BIM and LCA as essential methodologies for promoting sustainability in civil construction, particularly in water and sanitation building systems, improving efficiency and reducing environmental impacts. Previous studies indicate that this integration is complex, with challenges in interoperability between software. Method: The methodology adopted follows Design Science Research (DSR), using focus groups to elicit requirements, providing a collaborative and qualitative environment. The data was collected through focus groups made up of designers, professors and civil engineering students, conducted online and synchronously. Results and Discussion: The results show that the application of focus groups made it possible to identify functional and non-functional requirements relevant to the development of the artifact, as well as highlighting the importance of visualization and interoperability of the systems. The discussions show that the use of online focus groups is effective, although there are challenges related to adapting the methodology to a digital format. Research Implications: The implications of the research suggest that the use of Focus Groups in the elicitation of requirements for the tool results in better development of the computational tool for integrating BIM and LCA, meeting the expectations of the stakeholders and the system itself, which can improve sustainable design practices in civil engineering, especially in the area of sustainability in water and sanitary building systems. Originality/Value: The originality of the study lies in the use of synchronous online focus groups in a DSR approach to integrate BIM and LCA in water and sanitary installation projects, through the construction of software, contributing to the evolution of more sustainable practices in the construction industry.

This study evaluated the feasibility of using the waste Bege Bahia marble powder (BBMP) as a substitute for limestone filler in eco-friendly cement. Six cements were produced using eco-friendly clinkers containing varying ratios of BBMP, combined with 4.47% calcium sulfate and 25% carbonate material (either limestone filler or BBMP). Isothermal calorimetry, thermogravimetric analysis and X-ray diffraction were employed to assess hydration kinetics, thermal behavior, and mineralogical composition, respectively. The results indicate that completely replacing limestone with BBMP caused no significant changes in the hydration behavior or thermal performance compared to the reference cement. Therefore, it is believed that the BBMP as well as waste marble powder (WMP) with similar composition is a suitable substitute for limestone in clinker and cement production, contributing to reducing natural resources extraction and offering a solution for waste from the marble industry.
