Assessing the Involvement of Users During Development of Lower Limb Wearable Robotic Exoskeletons: A Survey Study.

OBJECTIVE: To explore user-centered design methods currently implemented during development of lower limb wearable robots and how they are utilized during different stages of product development. BACKGROUND: Currently, there appears to be a lack of standardized frameworks for evaluation methods and design requirements to implement effective user-centered design for safe and effective clinical or ergonomic system application. METHOD: Responses from a total of 191 experts working in the field of lower limb exoskeletons were analyzed in this exploratory survey. Descriptive statistics were used to present responses and measures of frequency, and chi-square tests were used to contrast the answers of respondents who identified as clinicians versus engineers. RESULTS: A vast majority of respondents involve users in their development, in particular at the initial and iterative stages, although some differences were found between disciplines. A variety of methods and metrics are used to capture feedback from users and test devices, and although valuable, some methods used may not be based on validated measures. Guidelines regarding tests on safety of exoskeletons also lack standardization. CONCLUSION: There seems to be a consensus among experts regarding the importance of a user-centered approach in exoskeleton development; however, standardized frameworks with regard to appropriate testing methods and design approaches are lacking. Such frameworks should consider an interdisciplinary focus on the needs and safety of the intended user during each iteration of the process. APPLICATION: This exploratory study provides an overview of current practice among engineers and clinicians regarding the user-centered design of exoskeletons. Limitations and recommendations for future directions are identified.

During the study of semivolatile compounds, lactic acid was found in the honey produced by four species of stingless bees. Moreover, other compounds were identified: 2-ethylhydroxy- propanoic acid in Melipona favosa honeys, 5-(hydroxymethyl)-2-furancarboxaldehyde and a-phenylmethyl benzene ethanol in Scaptotrigona mexicana honey, 2-butanol, heneicosane and heptacosane in Trigona carbonaria honey.

Adaptación lingüística y cultural de dos instrumentos para la detección de sospecha de maltrato hacia las personas mayores / Linguistic and cultural adaptation of two tools for the detecting suspected elder abuse

Este trabajo constituye la continuación natural del proyecto llevado a cabo por la Sociedad Española de Geriatría y Gerontología y el Instituto de Mayores y Servicios Sociales y auspiciado por la OMS y la Universidad de Ginebra, denominado «respuesta global al maltrato hacia las personas mayores incluyendo la negligencia: capacitación de los servicios de atención primaria para el abordaje de un problema mundial». Su realización ha sido posible gracias a la financiación del Instituto de Mayores y Servicios Sociales en el marco del Plan Nacional de Investigación Científica, Desarrollo e Innovación Tecnológica 2004–2007. El objetivo general de este proyecto era la validación tanto de un instrumento para la detección de sospecha de maltrato hacia las personas mayores denominado índice de sospecha de maltrato hacia las personas mayores (EASI) como del formulario de evaluación de trabajo social (FETS) cuyo objetivo era la confirmación de casos de sospecha de maltrato. Tras los resultados obtenidos, en este trabajo se presentan los cuestionarios obtenidos como resultado de la adaptación lingüística y cultural del índice de sospecha de maltrato hacia las personas mayores y del formulario de evaluación de trabajo social(AU)

This work is the natural continuation of the project conducted by the Spanish Geriatrics and Gerontology Society (SEGG) and the Institute for the Elderly and Social Services (IMSERSO) and under the auspices of the World Health Organisation and Geneva University, called “Global response to abuse and neglect of the elderly: Building Primary Health Care Services capacity to deal with a worldwide problem”. The carrying out of this work has been made possible due to funding by the Institute for the Elderly and Social Services (IMSERSO) in the framework of the National Plan for Scientific Research, Development and Technological Innovation 2004–2007. The general aim of this project was the validation of the tool for detecting suspected elder abuse, called (Elder Abuse Suspicion Index, EASI) as well as the Social Worker Evaluation Form (FETS) which is used for the confirmation of suspected abuse cases. After obtaining the results, the questionnaires obtained as a result of the linguistic and cultural adaptation of EASI and FETS are presented(AU)

Composition and antioxidant activity of Trigona carbonaria honey from Australia.

Stingless bees (Tribe Meliponini) are a diverse group of highly eusocial bees distributed throughout the tropics and subtropics. Trigona carbonaria honey, from Australia, was characterized by traditional physicochemical parameters (acidity, sugars, diastase, electrical conductivity, hydroxymethylfurfural, invertase, nitrogen, and water content) and other compositional factors (flavonoids, polyphenols, organic acids, and water activity), as well as total antioxidant capacity and radical scavenging activity. For the Australian T. carbonaria, the traditional analytical parameters were similar to those previously reported for neotropical stingless bee honey and confirm that honeys produced by Meliponini bees possess several physicochemical properties that are distinctly different from Apis mellifera honey, with higher values of moisture (26.5 +/- 0.8 g of water/100 g of honey), water activity (0.74 +/- 0.01), electrical conductivity (1.64 +/- 0.12 mS/cm), and free acidity (124.2 +/- 22.9 mEq/kg of honey) and a very low diastase activity (0.4 +/- 0.5 diastase number) and invertase activity (5.7 +/- 1.5 invertase number). The sugar spectrum was quite different from that of A. mellifera honey, with 20.3 +/- 2.9 g of maltose/100 g of honey. The values of pH (4.0 +/- 0.1), lactonic acidity (4.7 +/- 0.8 mEq/kg of honey), sucrose (1.8 +/- 0.4 g/100 g of honey), and fructose/glucose ratio (1.42 +/- 0.13) fell in the same ranges as those of A. mellifera honey. Citric (0.23 +/- 0.09) and malic (0.12 +/- 0.03) acid concentrations (in g/kg of honey) of T. carbonaria honeys were in the range described for A. mellifera honey. D-Gluconic was more concentrated (9.9 +/- 1.3 g/kg of honey), in the range of Italian Castanea, Thymus, Arbutus, and honeydew honeys. Flavonoid content was 10.02 +/- 1.59 mg of quercetin equivalents/100 g of honey, and polyphenol contents were 55.74 +/- 6.11 mg of gallic acid equivalents/100 g of honey. The antioxidant activity, expressed as percentage of 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) cation (ABTS(*+)) decolorization, was 233.96 +/- 50.95 microM Trolox equivalents, and free radical 1,1-diphenyl-2-picrylhydrazyl (DPPH(*)) depletion was 48.03 +/- 12.58 equivalents of ascorbic acid. All reported values are averages +/- standard deviation. The antioxidant activity can represent an important added value for T. carbonaria honey, to initiate a medicinal approach for both nutritional and pharmaceutical applications, besides further physicochemical characterization.
