This work presents the development and construction of an adaptive street lighting system that improves safety at intersections, which is the result of applying low-power Internet of Things (IoT) techniques to intelligent transportation systems. A set of wireless sensor nodes using the Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 standard with additional internet protocol (IP) connectivity measures both ambient conditions and vehicle transit. These measurements are sent to a coordinator node that collects and passes them to a local controller, which then makes decisions leading to the streetlight being turned on and its illumination level controlled. Streetlights are autonomous, powered by photovoltaic energy, and wirelessly connected, achieving a high degree of energy efficiency. Relevant data are also sent to the highway conservation center, allowing it to maintain up-to-date information for the system, enabling preventive maintenance.

Musculoskeletal disorders (MSD) are the most common source of occupational health problems in Western countries. In Spain, musculoskeletal disorders (MSDs) can be reported either as accidents or occupational diseases. When reported as an occupational disease, a full diagnosis is performed, as the compensation system needs the approval of the social security authority and a mandatory investigation has to be performed. Although many methods are available for investigating the causes of occupational accidents, occupational diseases have not been analysed with the same depth, and there is a lack of investigation methods. This paper aims to analyse the role of 43 occupational investigations of causes of musculoskeletal diseases in the prevention cycle. This study is based on the occupational investigations performed by workplaces’ occupational health and safety specialists when musculoskeletal diseases are reported. The analysis of the data involves descriptive statistics and the Φ coefficient. Based on administrative data, 68 workplaces employing 15,260 workers were surveyed and 41 workplaces with 13,201 workers submitted valid questionnaires to be analysed. The most frequent cause of reported musculoskeletal disease, in terms of primary risk, is repetitive movement. The only proposed measure with a significant association to the exposure by repetitive movements is job rotation (alternating workers between tasks within a job or between activities as a means to vary different levels of exposure). The investigation of occupational diseases has been useful in most of the cases for proposing preventive measures. Most of the workplaces surveyed have performed investigations and adopted preventive measures, but the managers of some workplaces were not aware of any disease notification regarding their workers when surveyed. More research is needed to provide tools for this important task.

La protección de la salud de las personas trabajadoras es una exigencia básica en el desarrollo de las relaciones sociales, políticas y comerciales presentes y futuras entre la Unión Europea y los países de Latinoamérica y el Caribe, entre otras regiones del mundo. La armonización del marco normativo y su aplicación real es un objetivo compartido por todas las partes. Dicho objetivo está alineado con los Objetivos de Desarrollo Sostenible de la Agenda 2030, en concreto el número 8, relacionado con el trabajo decente y productivo. Con estos planteamientos como premisa principal, el Vicerrectorado de Calidad, Igualdad y Responsabilidad Social y la Sede Santa María de la Rábida de la Universidad Internacional de Andalucía (UNIA), han promovido un Foro Iberoamericano que ha servido para poner sobre la mesa temas de actualidad en materia de salud laboral y prevención de riesgos laborales, debatidos en profundidad con expertos en la materia y agentes sociales y económicos de toda Iberoamérica. De esta forma, se han extraído conclusiones operativas que pueden ser de utilidad para los decisores de políticas públicas de nuestros países.…
