- Evaluation of perceived risk by education professionals in kindergartenPublication . Tavares, J.M.; Azevedo, R.P.; Vieira Da Silva, ManuelaThe present study aims to evaluate the perceived risk by education professionals of 8 Kindergarten of the city of Maia. A survey was applied to a sample of 34 kindergarten teachers and 34 auxiliary teaching staff. The results obtained revealed no statistical difference between risk perception of the two professionals groups, both occupational categories answered in general according to the requirements in the Portuguese legislation. The results also highlight the importance of risk communication and experi ence sharing as measures to decrease accident occurrence and increase the success of a safety culture

- Characterization of workers’ noise exposure of Portuguese industryPublication . Lopes, A.M.; Pinto, Edgar; Laranjeira, P.; Rebelo, M.; Oliveira, P.This study aimed to characterize the industrial workers’ noise exposure. The analysis was carried out using data from noise exposure assessment bulletins, prepared under the Prevenir program. This study covered eight sectors of Portuguese industry. The results showed that the sectors with higher levels of noise are the metallurgy and metalworking and also the wood and furniture. The quieter sectors are the textile and clothing industry, jewellery and watchmaking and chemical industry. Regarding the attenuation provided by hearing protection available to workers from the evaluated industries, the vast majority use earplugs with excessive attenuation.
- Applications of Proteomics in AquaculturePublication . Rodrigues, Pedro M.; Schrama, Denise; Campos, Alexandre; Osório, Hugo; Freitas, MarisaAquaculture is one of the fastest growing world industries due to the increased demand of fishery products for human consumption and capture restrictions as a result of aquatic ecosystems exploitation. Aquaculture is therefore an extremely competitive business with major challenges to keep a high quality farmed fish through a sustainable production system. These challenges imposed quite important changes in this more traditional market, namely at the level of integrating scientific knowledge and research. Proteomics presents itself as a powerful tool not only for a better understanding of the marine organisms biology but also to provide solutions to deal with changes and the increasing demand in the system’s production line to ensure the required supply. In this book chapter we will give an overview of aquaculture nowadays, its challenges and describe relevant proteomics studies in several areas of this industry. A brief description of the proteomics technical approaches applied to aquaculture will also be addressed.
- Noise Reduction and Control in Hospital Environment: Design of the NeoNoise ProjectPublication . Alberto Alves Carvalhais, Carlos; Vieira Da Silva, Manuela; Xavier, Ana; Santos, JoanaThe “NeoNoise Project: Integrated Approach to Minimize Sound Pressure Levels in Neonatal Intensive Care Units” is being conducted by the Research Group on Occupational and Environmental Health of the Research Center on Health and Environment in neonatal intensive care units, since exposure to sound pressure levels in these spaces has been recognized as a factor that influences the quality and well‐being of the occupants (workers and others), as well as the recovery of premature infants who are hospitalized. This work reports the rationale and the design of the NeoNoise project as well as the methods used for data collection. A brief review on the results published and available for the scientific community is also made. In general, NeoNoise project intends to make an integration of all relevant factors, with the intention of presenting a guiding document to change the working practices and occupant's behaviors. So far, this study provided data on sound pressure levels by objective and subjective approaches, as well as information about the exposure factors and sensitivity of the occupants to noise.
- Schoolbag weight and the postural and psychophysical changes in young students: A pilot studyPublication . Rodrigues, Matilde; Silva, Diana; Silva, Diogo; Santos, Rubim; Monteiro, Pedro; Loureiro, IsabelThis study aims to analyse the applicability of a new experimental procedure to determine bio- mechanical and psychophysical changes in young students, during the schoolbag carriage over one and two shoulders. A pilot study was performed, involving eight male students aged between 12 and 13 years old. Ex- perimental tests were also performed. The students were requested to walk on a treadmill for 10 minutes, with and without the backpack. The load of the backpacks was 10%, 15% and 20% of the students’ body weight (BW). Biomechanical and psychophysical changes were found. The results obtained are interesting to better understand the problem of students carrying heavily loaded schoolbags or carrying them improperly. Still, some limitations to the experimental procedure were pointed out.
- Health care staff perception of noise in neonatal intensive care units: a questionnaire survey from NeoNoise ProjectPublication . Alberto Alves Carvalhais, Carlos; Santos, J.; Coelho, M.; Xavier, A.; Silva, M.A hospital Neonatal Intensive Care Unit (NICU) is designed to treat premature infants who need special care. These kind of units have become quite sophisticated, with a sort of medical devices that support an array of health care staff, such, physicians, nurses, health technicians, etc. (Konkani & Oakley, 2012). Noise in NICU is recognized as an agent with negative implications on health and well-being of premature infants (Nicolau, Casal, Lopes, & Kronenberg, 2005) and health professionals (Carvalhais, Santos, Vieira da Silva, & Xavier, 2015). Noise in NICU, and its effects on patients and staff, such as physiological and psychological disorders, has become an important issue, particularly because in these case patients are mainly premature infants. Noise as a stressor does not only put pressure on the workers and may result in a higher error occurrence, but also affect in a negative way, the healing process of patients (Siegmann & Notbohm, 2013). Figure 1, presents a general noise reaction scheme which can be used for hypothesis testing in noise epidemiology considering the cause-effect (Babisch, 2002).
- Endophytic Actinobacteria for Sustainable Agricultural ApplicationsPublication . Carvalho, M. F.; Ma, Y.; Oliveira, Rui S.; Freitas, H.Endophytic actinobacteria have the capacity to establish intimate associations with plants and colonize their inner tissues without causing apparent disease symptoms. They can protect plants by producing bioactive compounds that act as plant growth promoters or biological control agents and, in return, obtain nutrition and protection from the host plant. The application of endophytic actinobacteria in agriculture has attracted increasing attention. We address isolation and identification methods and the occurrence and diversity of endophytic actinobacteria in agricultural crops. Attention is given to the roles of endophytic actinobacteria in plant growth and development and health promotion for sustainable agriculture is discussed.
