PURPOSE To describe and compare the content of instruments that assess environmental factors using the International Classification of Functioning, Disability and Health (ICF). METHODS A systematic search of PubMed, CINAHL and PEDro databases was conducted using a pre-determined search strategy. The identified instruments were screened independently by two investigators, and meaningful concepts were linked to the most precise ICF category according to published linking rules. RESULTS Six instruments were included, containing 526 meaningful concepts. Instruments had between 20% and 98% of items linked to categories in Chapter 1. The highest percentage of items from one instrument linked to categories in Chapters 2-5 varied between 9% and 50%. The presence or absence of environmental factors in a specific context is assessed in 3 instruments, while the other 3 assess the intensity of the impact of environmental factors. DISCUSSION Instruments differ in their content, type of assessment, and have several items linked to the same ICF category. Most instruments primarily assess products and technology (Chapter 1), highlighting the need to deepen the discussion on the theory that supports the measurement of environmental factors. This discussion should be thorough and lead to the development of methodologies and new tools that capture the underlying concepts of the ICF. :

Key priorities in biochar research for future guidance of sustainable policy development have been identified by expert assessment within the COST Action TD1107. The current level of scientific understanding (LOSU) regarding the consequences of biochar application to soil were explored. Five broad thematic areas of biochar research were addressed: soil biodiversity and ecotoxicology, soil organic matter and greenhouse gas (GHG) emissions, soil physical properties, nutrient cycles and crop production, and soil remediation. The highest future research priorities regarding biochar’s effects in soils were: functional redundancy within soil microbial communities, bioavailability of biochar’s contaminants to soil biota, soil organic matter stability, GHG emissions, soil formation, soil hydrology, nutrient cycling due to microbial priming as well as altered rhizosphere ecology, and soil pH buffering capacity. Methodological and other constraints to achieve the required LOSU are discussed and options for efficient progress of biochar research and sustainable application to soil are presented.

OBJETIVO Validar la version en portugues del World Health Organisation Disability Assessment Schedule (WHODAS 2.0). METODOS La version original con 36 items del WHODAS 2.0, administrada por entrevista, fue traducida al portugues de acuerdo con orientaciones internacionales, y evaluada en nueve participantes de la poblacion en general. La version en portugues fue aplicada en 204 pacientes con patologia musculoesqueletica. Se colectaron los datos sociodemograficos y de salud de los pacientes, asi como el numero de lugares donde presentaban dolor y su intensidad. El WHODAS 2.0 fue nuevamente aplicado por un segundo entrevistador, uno a tres dias posteriores a la primera entrevista para evaluar la confiabilidad inter-evaluadores. La validez del constructo fue evaluado con relacion a: capacidad del WHODAS 2.0 para diferenciar participantes con diferentes lugares con dolor y asociacion entre el WHODAS 2.0 y la intensidad del dolor. La consistencia interna tambien fue evaluada. RESULTADOS La version en portugues del WHODAS 2.0 fue de facil comprension, presento buena consistencia interna (α= 0,84) y confiabilidad inter evaluadores (CCI=0,95). Mostro ser capaz de detectar diferencias estadisticamente significativas entre individuos con diferente numero de lugares con dolor (p˂0,01) e indicar que mayor incapacidad esta asociada con la mayor intensidad del dolor (r=0,44, p˂0,01), indicando validez del constructo. CONCLUSIONES la version en portugues del WHODAS 2.0 se mostro confiable y valida al ser utilizada en pacientes con dolor asociado a la patologia musculo esqueletica.

Adaptive Robot Biped Locomotion with Dynamic Motion Primitives and Coupled Phase Oscillators

José Rosado; Filipe Miguel Teixeira Pereira da Silva; Vítor Santos; António Amaro

In order to properly function in real-world environments, the gait of a humanoid robot must be able to adapt to new situations as well as to deal with unexpected perturbations. A promising research direction is the modular generation of movements that results from the combination of a set of basic primitives. In this paper, we present a robot control framework that provides adaptive biped locomotion by combining the modulation of dynamic movement primitives (DMPs) with rhythm and phase coordination. The first objective is to explore the use of rhythmic movement primitives for generating biped locomotion from human demonstrations. The second objective is to evaluate how the proposed framework can be used to generalize and adapt the human demonstrations by adjusting a few open control parameters of the learned model. This paper contributes with a particular view into the problem of adaptive locomotion by addressing three aspects that, in the specific context of biped robots, have not received much attention. First, the demonstrations examples are extracted from human gaits in which the human stance foot will be constrained to remain in flat contact with the ground, forcing the “bent-knee” at all times in contrast with the typical straight-legged style. Second, this paper addresses the important concept of generalization from a single demonstration. Third, a clear departure is assumed from the classical control that forces the robot’s motion to follow a predefined fixed timing into a more event-based controller. The applicability of the proposed control architecture is demonstrated by numerical simulations, focusing on the adaptation of the robot’s gait pattern to irregularities on the ground surface, stepping over obstacles and, at the same time, on the tolerance to external disturbances.
