RESUMO
Despite the proved usefulness of drones in biodiversity studies, acquisition costs and difficulties in operating, maintaining and repairing these systems constrain their integration in conservation projects, particularly for low-income countries. Here we present the steps necessary to build a low-cost fixed-wing drone for environmental applications in large areas, along with instructions to increase the reliability of the system and testing its performance. Inspired by DIY (Do It Yourself) and open source models, this work prioritizes simplicity and accounts for cost-benefit for the researcher. The DIY fixed-wing drone developed has electric propulsion, can perform pre-programmed flight, can carry up to 500 g payload capacity with 65 minutes flight duration and flies at a maximum distance of 20 km. It is equipped with a RGB (Red, Green and Blue) sensor capable of obtaining 2.8 cm per pixel Ground Sample Distance (GSD) resolution at a constant altitude of 100 m above ground level (AGL). The total cost was $995 which is substantially less than the average value of similar commercial drones used in biodiversity studies. We performed 12 flight tests in auto mode using the developed model in protected areas in Brazil, obtaining RGB images that allowed us to identify deforestation spots smaller than 5 m2 and medium-sized animals. Building DIY drones requires some technical knowledge and demands more time than buying a commercial ready-to-fly system, but as proved here, it can be less expensive, which is often crucial in conservation projects.

OBJECTIVE:: to identify articles that assessed the effectiveness or efficacy of nonpharmacological interventions to improve quality of life of people with heart failure in the literature. METHOD:: an integrative literature review was performed in Lilacs, MedLine and SciELO databases, including randomized or nonrandomized clinical trials and quasi-experimental studies published between 2003 and 2014, in Portuguese, English or Spanish. RESULTS:: twenty-three studies were included. The categories of nonpharmacological interventions that improved quality of life of people with heart failure were: Remote health monitoring, Instructions on health practices, Physical activity follow-up and Traditional Chinese Medicine practices. CONCLUSION:: these results can guide the selection of interventions to be implemented by health professionals that treat people with heart failure. Future systematic reviews with meta-analyses are needed in order to identify the most effective interventions for improving these individuals' quality of life.

RESUMO Objetivo: identificar, na literatura, artigos que avaliaram a efetividade ou eficácia de intervenções não farmacológicas para melhorar a qualidade de vida de pessoas com insuficiência cardíaca. Método: revisão integrativa de literatura realizada nas bases de dados Lilacs, MedLine e SciELO, incluindo ensaios clínicos randomizados ou não randomizados e estudos quase-experimentais publicados entre 2003 e 2014, em português, inglês e espanhol. Resultados: foram incluídos 23 estudos. As categorias de intervenções não farmacológicas que melhoraram a qualidade de vida de pessoas com insuficiência cardíaca foram: Monitoramento remoto da saúde, Orientação sobre práticas de saúde, Acompanhamento de atividade física e Práticas de Medicina Tradicional Chinesa. Conclusão: estes resultados podem direcionar a seleção de intervenções a serem implementadas por profissionais de saúde que cuidam de pessoas com insuficiência cardíaca. Futuras revisões sistemáticas com metanálise são necessárias para identificar as intervenções mais eficazes para melhorar a qualidade de vida desses indivíduos.
RESUMEN Objetivo: identificar, en la literatura, artículos que evaluaron la efectividad o eficacia de intervenciones no farmacológicas para mejorar la calidad de vida de personas con insuficiencia cardíaca. Método: revisión integrativa de literatura realizada en las bases de datos Lilacs, MedLine y SciELO, incluyendo ensayos clínicos aleatorios o no aleatorios y estudios casi experimentales publicados entre 2003 y 2014, en portugués, inglés y español. Resultados: fueron incluidos 23 estudios. Las categorías de intervenciones no farmacológicas que mejoraron la calidad de vida de personas con insuficiencia cardiaca fueron: Monitoreo remoto de la salud, Orientación sobre prácticas de la salud, Acompañamiento de actividad física y Prácticas de Medicina China Tradicional. Conclusión: estos resultados pueden direccionar la selección de intervenciones a ser implantadas por profesionales de la salud que tratan de personas con insuficiencia cardiaca. Futuras revisiones sistemáticas con meta-análisis son necesarias para identificar las intervenciones más eficaces para mejorar la calidad de vida de estos individuos.
