The interpretation of the set of radiographs taken during the follow-up period after tooth replantation might pose several difficulties, especially the inability to adequately reproduce the projection geometry of the exposures. This article describes a method for the geometric standardization of intraoral radiographs using a custom-made apparatus comprising a film-holder attached to an occlusal...
Variation, long accepted to be the norm in otolaryngologic surgical practice, has recently come under scrutinization. Efforts can be seen daily in the operating room to standardize procedures with time-outs, checklists, and protocols. The thought is that by enforcing repetition and eliminating variation, it is possible to decrease human error and reduce cost. However, there is understandable re...
Performing a digital forensic investigation (DFI) requires a standardized and formalized process. There is currently neither an international standard nor does a global, harmonized DFI process (DFIP) exist. The authors studied existing state-of-the-art DFIP models and concluded that there are significant disparities pertaining to the number of processes, the scope, the hierarchical levels, and ...
Chemical variability of propolis is discussed with respect to the problem of standardization. Several chemical types of propolis are formulated, based on their plant source. Reliable criteria for chemical standardization of different propolis types are needed but such generally accepted criteria do not yet exist. The chemical profile of "poplar" propolis, typical for the temperate zone, can be ...
BACKGROUND The Canadian Health Measures Survey (CHMS) is an ongoing cross-sectional national survey that includes a measure of 25-hydroxyvitamin D [25(OH)D] by immunoassay. For cycles 1 and 2, the collection period occurred approximately every 2 y, with a new sample of ∼5600 individuals. OBJECTIVE The goal was to standardize the original 25(OH)D CHMS values in cycles 1 and 2 to the internatio...
This paper examines the effect of choice architecture on Massachusetts' Health Insurance Exchange. A policy change standardized cost-sharing parameters of plans across insurers and altered information presentation. Post-change, consumers chose more generous plans and different brands, but were not more price-sensitive. We use a discrete choice model that allows the policy to affect how attribut...
BACKGROUND Medical laboratories play a central role in health care. Many laboratories are taking a more focused and stringent approach to quality system management. In Korea, laboratory standardization efforts undertaken by the Korean Laboratory Accreditation Program (KLAP) and the Korean External Quality Assessment Scheme (KEQAS) may have facilitated an improvement in laboratory performance, b...
Cell migration research has recently become both a high content and a high throughput field thanks to technological, computational, and methodological advances. Simultaneously, however, urgent bioinformatics needs regarding data management, standardization, and dissemination have emerged. To address these concerns, we propose to establish an open data ecosystem for cell migration research.
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
BACKGROUND To provide the validated and standardized form of the Persian version of the Ages and Stages Questionnaires as an appropriate developmental screening tool for evaluation of Iranian children's development. METHODS This was a cross-sectional study. Translation and back-translation, content validity determination, cultural and lingual modifications, pilot study on 100 parents and inte...
