Peripheral refraction validity of the Shin-Nippon SRW5000 autorefractor

PURPOSE: To investigate the operation of the Shin-Nippon/Grand Seiko autorefractor and whether higher-order aberrations affect its peripheral refraction measurements. METHODS: Information on instrument design, together with parameters and equations used to obtain refraction, was obtained from a patent. A model eye simulating the operating principles was tested with an optical design program. Effects of induced defocus and astigmatism on the retinal image were used to calibrate the model eye to match the patent equations. Coma and trefoil were added to assess their effects on the image. Peripheral refraction of a physical model eye was measured along four visual field meridians with the Shin-Nippon/Grand Seiko autorefractor SRW-5000 and a Hartmann-Shack aberrometer, and simulated autorefractor peripheral refraction was derived using the Zernike coefficients from the aberrometer. RESULTS: In simulation, the autorefractor's square image was changed in size by defocus, into rectangles or parallelograms by astigmatism, and into irregular shapes by coma and trefoil. In the presence of 1.0 D oblique astigmatism, errors in refraction were proportional to the higher-order aberrations, with up to 0.8 D sphere and 1.5 D cylinder for ±0.6 μm of coma or trefoil coefficients with a 5-mm-diameter pupil. For the physical model eye, refraction with the aberrometer was similar in all visual field meridians, but refraction with the autorefractor changed more quickly along one oblique meridian and less quickly along the other oblique meridian than along the horizontal and vertical meridians. Simulations predicted that higher-order aberrations would affect refraction in oblique meridians, and this was supported by the experimental measurements with the physical model eye. CONCLUSIONS: The autorefractor's peripheral refraction measurements are valid for horizontal and vertical field meridians, but not for oblique field meridians. Similar instruments must be validated before being adopted outside their design scope.

La creación de valor en el museo y la sociomuseología

Los museos tienen normalmente mucha dificultad en justificar su existencia y en demostrar su valor real y su contribución al desarrollo de las comunidades a las que sirven. El coste del mantenimiento de un museo, después de inaugurado, nunca parece estar justificado para las tutelas y financiadores que lo promovieron. El museo, grande o pequeño, puede ser un elemento esencial en el desarrollo cultural del conjunto social, pero necesita tener una actividad que lo justifique y que su labor sea reconocida. Para contribuir con eficacia debe compartir con la comunidad su misión y sus actividades y para probar su valor debe tener sistemas de evaluación que permitan verificar si su labor de investigación y acción sobre el patrimonio, de promoción de la cultura y la ciudadanía y de colaboración con escuelas y asociaciones, reduce el fracaso escolar, aumenta la participación en la vida y cultura o contribuye a la cohesión social y a la formación de ciudadanos más responsables y solidarios. La Sociomuseología estudia estos campos de la actividad del museo, acompaña experiencias y propone soluciones a estas dificultades.

Dynamic Distance-Based Shape Features for Gait Recognition

We propose a novel skeleton-based approach to gait recognition using our Skeleton Variance Image. The core of our approach consists of employing the screened Poisson equation to construct a family of smooth distance functions associated with a given shape. The screened Poisson distance function approximation nicely absorbs and is relatively stable to shape boundary perturbations which allows us to define a rough shape skeleton. We demonstrate how our Skeleton Variance Image is a powerful gait cycle descriptor leading to a significant improvement over the existing state of the art gait recognition rate.

Volunteer coaches are critical for the existence of youth sports organizations. They are both leading the activity and are expected to develop the athletes in a technical, psychological, social and cultural way. The mission as a coach requires skills and knowledge from a wide range of fields and the mission as a coach appears complex. Stakeholders like Riksidrottsförbundet, Gymnastikförbundet and the sport organization have certain requirements on how to design the activities. Coaches have to follow those guidelines and implement them in practice. The social context is one important factor for understanding the driving force. It affects how coaches perceive their assignment as a volunteer coach. This study aims to contribute to increased understanding of the fenomen volunteer coach mission and increase understanding for the drivers of volunteer coaches in gymnastics. In order to clarify this, 6 interviews with volunteer coaches from gymnastics organizations linked to Riksidrottsförbundet were conducted. This study indicates that the motive behind the coaching mission is grounded in an intrinsic value of being a coach. The coaching mission itself appears partly contradictory when trying to combine the sport related and the social dimensions. Seeing progress from practice and to follow the development of gymnasts are aspects that drives coaches. That combined with the social interaction is important for understanding the drivers of being a coach.

Estratégias de sustentabilidade financeira das IPSS

Enquadramento: As IPSS debatem-se com constrangimentos de ordem financeira que podem ameaçar o seu desempenho. O Estado é o seu maior financiador, mas a tendência de diminuição dos apoios públicos impõe às IPSS encontrem outras formas de financiamento. As IPSS devem garantir a sua sustentabilidade financeira através da diversificação das fontes de financiamento (aumento do financiamento privado) e da implementação de estratégias de redução de custos e aumento das receitas. A gestão dos recursos das IPSS deve ser realizada de uma forma eficiente e eficaz, com vista à construção de uma organização sustentável que cumpra a sua missão e atinja os seus objetivos de carácter social. Objetivos: O objetivo geral do estudo é o seguinte: identificar as estratégias de financiamento que fomentam a sustentabilidade das IPSS. Os objetivos específicos são os seguintes: (1) Conhecer a tipologia das fontes de financiamento das IPSS; (2) Identificar os benefícios e os riscos da diversificação das fontes de financiamento das IPSS; (3) Analisar as fontes de receitas e de custos das IPSS; (4) Identificar os fatores que contribuem para vulnerabilidade financeira das IPSS; (5) Identificar as ações das IPSS que visam uma melhoria da sua sustentabilidade financeira. Métodos: Estudo de caso de 4 IPSS, com utilização de entrevista semi-estruturada (9 entrevistas) e análise documental. Recurso ao software NVivo 10 para categorização dos dados e à análise de conteúdo para interpretação dos dados recolhidos. Resultados:Os Acordos de Cooperação com a Segurança Social são a melhor estratégia para garantir a sustentabilidade financeira das IPSS. Estas desenvolvem um conjunto de ações que visam a melhoria da sua sustentabilidade económica, tais como, a rentabilização de recursos, a redução de despesas, o desenvolvimento de serviços de valor acrescentado e a angariação de recursos. As IPSS sentem necessidade de diversificar as fontes de financiamento (desenvolvimento de atividades complementares como fonte de receita) e apresentam preocupações relacionadas com o cumprimento da sua missão social (intervenção orientada para as necessidades dos stakeholders). Implicações:O estudo sugere a importância das IPSS diversificarem as suas fontes de financiamentoe explorar iniciativas de carácter privado que permitam criar lucro para desenvolver os objetivos e a missão da organização. Recomenda-se a replicação do estudo com uma amostra mais alargada.

Ampliação de movimentos na dança circular com pessoas com deficiência visual

This paper aims at studying how circular dance can afford to sight-disabled peoples movement and how they can learn to cope with the deep movement of relation, consciousness, appropriation and communion with the world. Inside circular dance, a cosmic metaphor, is inscribed the movement of the world, which tells and changes amorously the human history. In the works of Paulo Freire and Maurice Merleau-Ponty one can find the necessary support to discuss, as long as possible, movement and existence. Research-action is used as a methodological approach whose empirical center is placed on the Institute of Education and Rehabilitation of Blind, in Natal, which shelters eight sightdisabled adults. The research s data reveal that the practice of circular dance concurs to enlarge the movement of the research s subjects, to develop a more accurate perception of their selves and of their own capacities, as well as improve the relations Me/Others, Me/World, which require a context of differences. The study has revealed that the practice of dance develops a better perception of the limits and surpasses as a human condition and, in consequence, the discovery of one s own body and the other s body as a resource of lessons and representations of the self and of the world. It lets out the development of a new way of thinking and coping with discrimination surrounding the disabled persons. In movement, in circular dance, the barrier between sight disablement and vision loses force.

Quantification of the human postural control system to perturbations

Human standing posture is inherently unstable. The postural control system (PCS), which maintains standing posture, is composed of the sensory, musculoskeletal, and central nervous systems. Together these systems integrate sensory afferents and generate appropriate motor efferents to adjust posture. The PCS maintains the body center of mass (COM) with respect to the base of support while constantly resisting destabilizing forces from internal and external perturbations. To assess the human PCS, postural sway during quiet standing or in response to external perturbation have frequently been examined descriptively. Minimal work has been done to understand and quantify the robustness of the PCS to perturbations. Further, there have been some previous attempts to assess the dynamical systems aspects of the PCS or time evolutionary properties of postural sway. However those techniques can only provide summary information about the PCS characteristics; they cannot provide specific information about or recreate the actual sway behavior. This dissertation consists of two parts: part I, the development of two novel methods to assess the human PCS and, part II, the application of these methods. In study 1, a systematic method for analyzing the human PCS during perturbed stance was developed. A mild impulsive perturbation that subjects can easily experience in their daily lives was used. A measure of robustness of the PCS, 1/MaxSens that was based on the inverse of the sensitivity of the system, was introduced. 1/MaxSens successfully quantified the reduced robustness to external perturbations due to age-related degradation of the PCS. In study 2, a stochastic model was used to better understand the human PCS in terms of dynamical systems aspect. This methodology also has the advantage over previous methods in that the sway behavior is captured in a model that can be used to recreate the random oscillatory properties of the PCS. The invariant density which describes the long-term stationary behavior of the center of pressure (COP) was computed from a Markov chain model that was applied to postural sway data during quiet stance. In order to validate the Invariant Density Analysis (IDA), we applied the technique to COP data from different age groups. We found that older adults swayed farther from the centroid and in more stochastic and random manner than young adults. In part II, the tools developed in part I were applied to both occupational and clinical situations. In study 3, 1/MaxSens and IDA were applied to a population of firefighters to investigate the effects of air bottle configuration (weight and size) and vision on the postural stability of firefighters. We found that both air bottle weight and loss of vision, but not size of air bottle, significantly decreased balance performance and increased fall risk. In study 4, IDA was applied to data collected on 444 community-dwelling elderly adults from the MOBILIZE Boston Study. Four out of five IDA parameters were able to successfully differentiate recurrent fallers from non-fallers, while only five out of 30 more common descriptive and stochastic COP measures could distinguish the two groups. Fall history and the IDA parameter of entropy were found to be significant risk factors for falls. This research proposed a new measure for the PCS robustness (1/MaxSens) and a new technique for quantifying the dynamical systems aspect of the PCS (IDA). These new PCS analysis techniques provide easy and effective ways to assess the PCS in occupational and clinical environments.
