Une approche comparée des principes de proportionnalité et de subsidiarité dans la jurisprudence de la CJUE et du TJCA: la coordination-harmonisation des pluralismes juridiques régionaux à l’épreuve de l’internationalisation du droit de l’intégration

Face à la complexité de la comparaison entre les droits de l’Union européenne et de la Communauté andine caractérisés par une internationalisation pluraliste croissante, l’idée de coordination du pluriel appelle l’émergence de «macro-principes» pour penser l’universalité juridique, tant dans sa diversité que dans son unité, dans le cadre d’un système juridique supranational. Sur ce point, un constat liminaire s’impose: on ne peut aujourd’hui définir les frontières d’un droit communautaire internationalisé car elles sont floues et ouvertes. Il convient dès lors de prendre comme point de départ une étude du noyau de cette internationalisation qui passe par une comparaison de principes à vocation universelle («macro principes»). En ce sens, la proportionnalité et la subsidiarité peuvent faire l’objet d’une analyse à travers une étude comparée de la jurisprudence de la CJUE et du TJCA. Le premier principe peut ainsi être vu comme un moyen de coordination de droits communautaire tandis que le second se révèle être un outil de coordination de compétences communautaires. 

Implementation of ‘School Back’ by the ‘Core’ technique in a factory of geotextiles to prevent back pain

Introduction: This article aims to show an alternative intervention for the prevention and control of back pain to the people of a production plant of geotextiles for the construction exposed to handling and awkward postures through the implementation of the Back School using the CORE technique. This technique being understood as trainer of the stability musculature of the spine; whose benefit is proportionate the muscular complex of the back, stability and avoid osteomuscular lesions and improved posture. Objective: To present the results about the implementation of the back school by the CORE technique for prevention of back pain in a population of forty-eight male collaborators. Materials and methods: The back school began with talks of awareness by the occupational health physician explaining the objectives and benefits of it to all participants. Once this activity was done, was continued to evaluate all plant employees to establish health status through the PAR-Q questionnaire, who were surveyed for the perception of pain using visual analog scale (VAS) and stability was determined column through the CORE assessment, to determine the training plan. Then, were made every six months the revaluations and implementation of a survey of assistant public perception to identify the impact of the implementation of the school back on the two variables referred (pain perception and stability of column). Results: The pain perception according VAS increased in the number of workers asymptomatic in 12% and based in the satisfaction survey 94% of population reported that with the development of this technique decrease the muscle fatigue in lumbar level; and 96% of population reported an improvement in the performance of their work activities. Discussion: Posterior to the analysis of all results, it is interpreted that back schools practice through CORE technique, contributes to the prevention and / or control of symptoms at the lumbar level in population of productive sector exposed to risks derived from the physical load, provided that ensure its continuously development and supervised for a competent professional.
