Abstract: The main objective of this study is to evaluate the impact of school furniture and work surface lighting on the body posture of two public Middle School students from Paraíba (Brazil). The target population included 8th grade groups involving 31 students. Brazilian standards for lighting levels, the CEBRACE standards for furniture measurements and the Postural Assessment Software (SAPO) for the postural misalignment assay were adopted for the measurements comparison. The statistic analysis includes analyses of parametric and non-parametric correlations. The results show that the students' most affected parts of the body were the spine, the regions of the knees …and head and neck and about 90% of the students presented postural misalignment. The lighting levels were usually found below 300 lux, below recommended levels. Such results indicate the need of investments in more suitable school furniture and structural reforms aimed at improving the lighting in the classrooms, which could fulfill the students' profile and reduce their complaints.

Abstract: Behaviour patterns specific to children pose them at greater risk of environmental hazards than adults. Ergonomics is the science of matching human interaction with the proximate environment. Conventionally ergonomic principles were applied on adult work places to ensure safety of the working environment. With emerging scientific evidence, school environments are being a focus to apply ergonomic principles. Children spend more time within schools during critical developmental stages of their life. Everybody feels that the schools are safe places, but they are not. A multitude of ergonomic hazards have been identified in school settings. Widespread mismatches between anthropometry and school furniture, …heavy schoolbag carriage and unhealthy bag behaviour are significant. Negative effects range from general tiredness, musculoskeletal pains, spinal deviations, shoulder level shifts, injuries and psychological disturbances. There are fragmented efforts to widen ergonomic concepts to health care professionals and other stakeholders of child health. Addressing ergonomic issues will ensure that children, the future productive generation contributing to economic growth and development of a country, are provided with opportunities in a healthy environment. This paper emphasizes the need for a concerted effort on widening the scope of ergonomics to cater for the evolving demand. Show more

Abstract: A study in the educators' work station at baby nursery of NDI/UFSC, located in Florianópolis, was conducted using the Work Ergonomic Analysis methodological tool. The demand considered was the educators' physical exhaustion caused by the weight carried when taking care of the babies, the postures assumed during the labor activity and the spatial arrangement of the baby nursery. Thinking ergonomically, the spatial arrangement is directly associated to three factors: the formal aspect of the environment, the esthetic aspect including colors and finish quality and the ease of understanding involved in the baby nursery labor. By the ergonomic adequacy it is …possible to assert that if were established better conditions of posture and comfort for the educators, as well as satisfactory technical and operational information to carry out the activities, greater safety and welfare would be provided to the babies, the main focus of the work.

Abstract: The double journey (work and study) may result or aggravate health problems, including sleep disturbances, as observed in previous studies with high school students. The aim of this study is to analyze the sleep-wake cycle and perceived sleepiness of working college students during weekdays. Twenty-three healthy college male students, 21-24 years old, working during the day and attending classes in the evening, participated in this study. During five consecutive days, the students filled out daily activities logs and wore actigraphs. Mean sleeping time was lower than 6 hours per night. No significant differences were observed in the sleep-wake cycle during …the weekdays. The observed lack of changes in the sleepwake cycle of these college students might occur as participants were not on a free schedule, but exposed to social constraints, as was the regular attendance to evening college and day work activities. Sleepiness worsened over the evening school hours. Those results show the burden carried by College students who perform double activities - work and study. Show more

Abstract: Schoolbag use by children is a global common concern.. Children carry school books and other amenities in their school bags. Global evidence indicates that daily load carried by school children may have negative health implications. Backpack as a school bag model, is the healthiest way of load carriage for school children. Several initiatives have been launched world over to minimize unhealthy consequences resulting from schoolbags. Based on a situation analysis, Sri Lanka implemented a national healthy schoolbag campaign by joint efforts of Ministries of Health and Education. Actions were contemplated on; strategies for bag weight reduction, introduction of an ergonomically …modeled schoolbag and bag behaviour change. New strategies were introduced with awareness campaigns to policy makers, bag manufacturers, parents, teachers and children. Four million schoolchildren benefitted. In 2000, the backpack strategy of “Pack it Light, Wear it Right” was started as a public health initiative in the United States by the American Occupational Therapy Association (AOTA). Over the last eleven years, thousands of occupational therapy practitioners and students participated in educational programs and outreach activities. In 2004, modeled after the success AOTA initiative, the Icelandic Occupational Therapy Association launched a national backpack awareness initiative. This article shares examples of practices that could be implemented in any context to the promote health of children. Show more

Abstract: The paper presents the development of a cutting tool guide, specifically for the harvest of bamboo. The development was made based on precepts of eco-design and ergonomics, for prioritizing the physical health of the operator and the maintenance of the environment, as well as meet specific requirements of bamboo. The main goal is to spread the use of bamboo as construction material, handicrafts, among others, from a handy, easy assembly and material available tool.

Abstract: This paper, which stems from a developing research project, aims to disseminate among the international scientific community the thought of Daciano da Costa (1930-2005) given the importance he conferred to Ergonomics, throughout his teaching career and his professional practice as a reference figure in the Design of the twentieth century in Portugal. We focus on the important role played by Ergonomics within the conceptual Design process, through the case study Daciano da Costa.What Daciano brought to the practice and teaching was a modernization of processes, a new perspective on the emerging themes of design, like ergonomics. Daciano believed that designing …was providing a service. This task was understood as the building of a relationship with users. One of his distinguished features was the particular attention he paid to the unique aspects of the scale of proximity: the scale of the hand, of the immediate gesture, of the body. As a professor he insisted not so much on the end product, but rather on the recognition of the research process and how it was conducted. When designing, developing and supervising the exercises he set, ergonomic factors were one of his main concerns. Show more
