The Development and Precision of a Custom-Made Skitester
2021
In the sport of cross-country skiing, equipment has a direct influence on results. Ski teams do extensive testing of different ski base grinds and products on a yearly basis. To achieve reliable results, the quality of methods used for testing skis needs to be taken in to account in addition to factors including the physical characteristics of testing personnel and changes in weather conditions. The aim of this study was to introduce a custom-made skitester, that was developed for testing skis on real snow, in laboratory conditions, and to evaluate its precision. The current skitester is capable of glide testing both classic and skate skis as well as kick simulation for the testing of grip …
Capturing cognitive load management during authentic virtual reality flight training with behavioural and physiological indicators
2023
Background Cognitive load (CL) management is essential in safety-critical fields so that professionals can monitor and control their cognitive resources efficiently to perform and solve scenarios in a timely and safe manner, even in complex and unexpected circumstances. Thus, cognitive load theory (CLT) can be used to design virtual reality (VR) training programmes for professional learning in these fields. Objectives We studied CL management performance through behavioural indicators in authentic VR flight training and explored if and to what extent physiological data was associated with CL management performance. Methods The expert (n = 8) and novice pilots (n = 6) performed three approac…
Exploring the conceptual framework and measurement model of intrinsic capacity defined by the World Health Organization: A scoping review
2022
WHO has defined intrinsic capacity (IC) as the composite of all physical and mental capacities of an individual covering five subdomains: cognition, locomotion, sensory, vitality, and psychological. Despite this well accepted definition, the conceptual and measurement model of IC remains unclear, which hampers a standardized operationalization of the construct. We performed a scoping review to give a comprehensive overview of the extent to which the current literature of IC addresses and assumes the conceptual framework and measurement model of IC as reflective or formative. For inclusion, we considered all types of articles that were published in peer-reviewed journals except for protocol …
Wybrane narzędzia i metody ewaluacji jakości informacji na stronach WWW
2016
Celem opracowania jest przedstawienie wybranych metod i narzędzi oceny jakości informacji na stronach WWW oraz identyfikacja ich wspólnych kryteriów ewaluacji. Zaprezentowane w publikacji kryteria oceny jakości informacji w większości przypadków znalazły zastosowanie w badaniu jakości informacji medycznej oraz dotyczącej zdrowia. Na podstawie zaprezentowanych pięciu metod/narzędzi utworzono zestawienie wspólnych kryteriów, dotyczących oceny jakości informacji w serwisach internetowych.
Style partycypacji kulturalnej człowieka dorosłego : walidacja narzędzia pomiarowego
2017
Artykuł przedstawia proces walidacji narzędzia pomiarowego, diagnozującego style partycypacji kulturalnej człowieka dorosłego. Jego celem jest opis uzyskanych wyników w poszczególnych etapach walidacji oraz określenie związku pomiędzy stylami partycypacji kulturalnej a układami kultury prezentowanymi przez socjologów kultury. W związku z czym przedmiotem badań jest styl partycypacji kulturalnej człowieka dorosłego. Badania pilotażowe, jak i właściwe zostały przeprowadzone w województwie opolskim, próba badawcza kolejno liczyła 100, a następnie 400 respondentów. Za podstawę teoretyczno-metodologiczną rozważań przyjęto konstrukt teoretyczny Kazimierza Obuchowskiego, opisujący podmiotowy oraz …
Efficient design and modeling strategies for follow-up studies with time-varying covariates
2015
Epidemiological studies can often be designed in several ways, some of which may be more optimal than others. Possible designs may differ in the required resources or the ability to provide reliable answers to the questions under study. In addition, once the data are collected, the selected modeling approach may affect how efficiently the data are utilized. The purpose of this dissertation is to investigate efficient designs and analysis meth ods in follow-up studies with longitudinal measurements. A key question is how to select optimally a subcohort for a new longitudinal covariate measurement if we cannot afford to measure the entire cohort. Another key question we consider is how to determine …
Effect of low dissolved oxygen on the viability of juvenile Margaritifera margaritifera : Hypoxia tolerance ex situ
2022
The decline of endangered freshwater pearl mussel (FPM, Margaritifera margaritifera) has been attributed to juvenile mortality caused by low concentrations of dissolved oxygen in the stream substrate resulting from fine sediments (siltation) that impede water exchange in the interstitial microhabitat of juveniles. If low oxygen concentration causes recruitment failure of FPMs, knowledge on the oxygen tolerance of juvenile FPMs is essential for the conservation of the species, as it will justify conservation efforts improving water exchange in the bottom gravel. However, the tolerance of low oxygen of FPM juveniles has not been directly studied. Juvenile FPMs (9–11 months old) were exposed i…
Digital Correlation Method Based on Micro-geometrical Texture Pattern for Strain Field Measurement
2011
International audience; Image correlation methods are widely used in experimental mechanics to obtain displacement field measurements. Currently, these methods are applied using digital images of the initial and deformed surfaces sprayed with black or white paint. Speckle patterns are then captured and the correlation is performed with a high degree of accuracy to an order of 0.01 pixels. In 3D, however, stereo-correlation leads to a lower degree of accuracy. Correlation techniques are based on the search for a sub-image (or pattern) displacement field. The work presented in this paper introduces a new correlation-based approach for 3D displacement field measurement that uses an additional …
