- Avaliação das condições higio-sanitárias nas piscinas municipais do Grande PortoPublication . Silva, Ana Sofia; Queirós, Ana Inês; Silva, ManuelaNos últimos anos, tem-se verificado um aumento da procura de piscinas para atividades desportivas, recreativas e terapêuticas, acentuando desta forma a importância de questões ligadas à qualidade, às características estruturais, e às condições de funcionamento das piscinas. Contudo, nem a qualidade da água, nem as condições de instalação e de funcionamento das piscinas são objeto de regulamentação, com exceção das piscinas incluídas em recintos com diversões aquáticas, empreendimentos turísticos e hidroterapia. No entanto, existem documentos que podem ser usados como referência, Diretiva 23/93, NP 15288-1:2009, 15288-2:2009 e NP 4542:2017.
- Main complaints from workers at type I indoor swimming poolsPublication . Silva, Ana Sofia; Queirós, Ana Inês; Silva, ManuelaIn recent years, users have increased the demand for swimming pools, implying an increase in the number of workers. The main objective of this study is to identify the main complaints of workers, describe the possible consequences for the health of workers and the population, and propose mitigation measures. Nine municipal swimming pools in the metropolitan area of Porto participated in this study. The pool workers answered a questionnaire to identify the main complaints and symptoms in the work environment. The data were processed using SPSS IBM Statistics 27. Workers' main symptoms/complaints were chlorine smell, heat, temperature differences, noise, and fatigue. As mitigation measures, it is essential to make the pool ventilation system more effective, implement regular assessments of air quality, thermal environment, noise and illuminance.
- Utilization of Quality Tools: does sector and size matter?Publication . Fonseca, Luís; Lima, Vanda; Silva, ManuelaThis research focuses on the influence of company sector and size on the level of utilization of Basic and Advanced Quality Tools. The paper starts with a literature review and then presents the methodology used for the survey. Based on the responses from 202 managers of Portuguese ISO 9001:2008 Quality Management System certified organizations, statistical tests were performed. Results show, with 95% confidence level, that industry and services have a similar proportion of use of Basic and Advanced Quality Tools. Concerning size, bigger companies show a higher trend to use Advanced Quality Tools than smaller ones. For Basic Quality Tools, there was no statistical significant difference at a 95% confidence level for different company sizes. The three basic Quality tools with higher utilization were Check sheets, Flow charts and Histograms (for Services) or Control Charts/ (for Industry), however 22% of the surveyed organizations reported not using Basic Quality Tools, which highlights a major improvement opportunity for these companies. Additional studies addressing motivations, benefits and barriers for Quality Tools application should be undertaken for further validation and understanding of these results.
