A staff canteen in the workplace can offer a healthier diet, which may lower the blood pressure (BP). The purpose of this paper is to evaluate whether the presence of staff canteen in the workplace is associated with consumption of healthy food and lower systolic and diastolic BP.

A cross-sectional study was conducted, randomly selecting workers through a multistage sampling, stratified by company size in Brazil. Demographic, socioeconomic, and life style characteristics were evaluated, and weight, height, and BP were measured. Statistical analysis used generalized linear models, controlling for design effect and confounding factors, to assess the association between BP and staff canteen and the intake of food items.

In total, 4.818 workers, aged 35.4±10.7 years, 76.5 percent men, with 8.7±4.1 years of formal education were enrolled. Prevalence of hypertension was 24.7 percent (p-value <0.001) among workers from industries with staff canteen vs 30.6 percent among those with no staff canteen. Workers of industries with staff canteen consumed higher proportion of fruits, green leafy vegetables, and milk than workers of industries without canteen, and had lower systolic and diastolic BP, independently of the frequency of intake.

Workers of industries with staff canteen consumed a healthier diet, and had lower systolic and diastolic BP, and lower prevalence of hypertension than workers from workplaces without staff canteen.

This study was the first carried out among workers of industries reporting that the presence of a staff canteen in the workplace is associated with lower systolic and diastolic BP and prevalence of hypertension.

This chapter discusses how young Black people produce social agency through the sphere of culture, based on hip-hop. Divided into two parts, it surveys theses and dissertations produced in Brazilian universities on the subject in the last ten years. In a second moment, it proposes a research methodology that takes young people as narrators of their social experiences, emphasizing how they think about the school space. The work is an exploratory study and seeks the interposition between formal schooling and the cultural practices of hip-hoppers. It intends to affirm hip-hop as a power, an affirmative form of an ethic of life, a way of life, and a way of escaping the established places for poor, Black young people from the suburbs. It is also intended to show how hip-hop, a marginal culture, has triggered a game of cultural positions within the school and displaced provisions of power.

Although the adoption of metal additive manufacturing (AM) for production has continuously grown, in-house access to production grade metal AM systems for small and medium enterprises (SMEs) is a major challenge due to costs of acquiring metal AM systems, specifically powder bed fusion AM. On the other hand, AM technology in directed energy deposition (DED) has been evolving in both: processing capabilities and adaptable configuration for integration within existing traditional machines that are available in most SME manufacturing facilities, e.g. computer numerical control (CNC) machining centers. Integrating DED with conventional processes such as machining and grinding into Hybrid AM is well suited for remanufacturing of metal parts. The paper aims to discuss these issues.

Classical facility location models are employed to understand the effects of SMEs adopting DED systems to offer remanufacturing services. This study identifies strategically located counties in the USA to advance hybrid AM for reverse logistics using North American Industry Classification System (NAICS) data on geographical data, demand, fixed and transportation costs. A case study is also implemented to explore its implications on remanufacturing of high-value parts on the reverse logistics supply chain using an aerospace part and NAICS data on aircraft maintenance, repair and overhaul facilities.

The results identify the candidate counties, their allocations, allocated demand and total costs. Offering AM remanufacturing services to traditional manufacturers decreases costs for SMEs in the supply chain by minimizing expensive new part replacement. The hubs also benefit from hybrid AM to repair their own parts and tools.

This research provides a unique analysis on reverse logistics through hybrid AM focused on remanufacturing rather than manufacturing. Facility location using real data is used to obtain results and offers insights into integrating AM for often overlooked aspect of remanufacturing. The study shows that SMEs can participate in the evolving AM economy through remanufacturing services using significantly lower investment costs.
