Colombia is a country that is characterized by having potential in many renewable and sustainable energy sources such as solar, wind, hydroelectric, biomass, etc., in this country the growth value of renewable energy (ER) has not yet reached a benchmark, this due to the existence of several barriers or limitations that have hindered the path of research and implementation. It is difficult to identify and prioritize the impact of these barriers that mostly hinder growth or improvement in the quality of life of a specific population. For this research, a systematic structure has been developed to identify and prioritize the barriers and manage to find a solution path to the aforementioned. This study aims to recognize and classify the barriers according to their impact on the development of renewable energy technologies, as well as demonstrate the non-relationship that may exist between a territory rich in energy potential and the good quality of life of its inhabitants, the study consists of four phases; (1) A study area was taken for its characterization in renewable energy potential and compared with the current quality of its inhabitants, (2) The barriers were recognized from the available literature studies, project reports and interactions with 6 experts from academia and industries, (3) for the final selection, the FAHP decision method was used, then, 24 were selected and classified into five groups: social and economic barriers, political and, administrative and market barriers and geographical and environmental barriers and (4) the FAHP method was used to obtain the priority weight and the hierarchy between these barriers. The results showed first that there is no relationship indicating that a potential area in renewable energy source has a positive impact on people's quality of life, also that politics and political barriers occupies the first place among the main barriers, besides that corruption and nepotism is the most relevant sub-criterion according to the experts’ results. Sensitivity analysis is used to confirm the stability of all prioritized barriers.

More than 70% of subjects have excess skin (ES) after bariatric surgery causing physical and psychosocial daily life inconveniences. These negative consequences may be a barrier to the practice of physical activity (PA), which is highly recommended to optimize bariatric surgery results. Thus, the purpose of this study was to evaluate the impact of ES on the practice of PA in women who have undergone bariatric surgery. Questionnaires administrated to 26 women (29.1AE0.8kg.m 2), who underwent bariatric surgery 2AE0.2 years before, evaluated daily life inconveniences and mobility limitations caused by ES, the practice of PA, physical self-perception and physical exercise beliefs. We used the 6-min walking test and muscular endurance tests to evaluate the physical fitness and photographs with anatomic markers to quantify ES. Among the subjects, 76.9% declared mobility limitations caused by ES during the practice of PA and 45.2% stated avoiding PA because of ES, which caused sloshing, weightiness, hygiene problems and people staring. The women avoiding PA because of ES had significantly lower physical selfperception, physical fitness and more embarrassment during PA without significant difference in the magnitude of ES (p¼0.06), BMI, daily life inconveniences and energy expenditure compared to women not avoiding PA. ES is a barrier to practice PA in some patients, but does not prevent the regular practice of PA and the magnitude of ES does not seem to be related to the PA avoidance.
