Cryptris 1/2. Comprendre une des techniques les plus sophistiquées de cryptographie en... jouant à Tetris.
National audienceÉchanger des informations secrètes sur Internet ? C'est possible. Mais il y a toujours un risque qu'elles soient interceptées. C'est là que les mathématiques viennent à la rescousse. Et la méthode des " réseaux euclidiens " promet d'être encore plus efficace que les méthodes standard. De plus, il se trouve qu'on peut la comprendre en jouant à un jeu vidéo aux allures de Tetris, qui s'appelle " Cryptris "
DURAPI – Vers une meilleure connaissance et un accompagnement technique des exploitations apicoles professionnelles : durabilité, stratégies de renouvellement du cheptel et conséquences sur le fonctionnement global de l’exploitation
Variability of the production context, colony losses: professional beekeepers have to cope with several environmental and socio-economic issues to ensure the sustainability of their farm. Thus, the DURAPI project aimed at developing a sustainability assessment framework for bee farming operations through a participatory design involving the stakeholders from the beekeeping sector. We also considered the part of the colony and queen replacement strategy, which is central in the colony management: the existing replacement strategies were identified and their possible consequences on the farm sustainability, in particular on the work organisation, were studied. These results allowed us to develop training tools for future beekeepers. This project also provides several support tools for beekeeping advisors.Variabilité du contexte de production, pertes de colonies d’abeilles : les exploitations apicoles font aujourd'hui face à différentes problématiques environnementales comme socio-économiques. Dans ce contexte, le projet DURAPI a visé à élaborer un cadre d’évaluation de la durabilité de ces exploitations, à travers une démarche participative qui a impliqué de nombreux acteurs de la filière. Parallèlement, la place de la gestion du renouvellement des colonies et des reines dans cette durabilité a été considérée. Les principales stratégies de renouvellement du cheptel mises en place dans les exploitations ont ainsi été identifiées afin d’ensuite caractériser leurs conséquences possibles sur cette durabilité de l’exploitation, notamment en termes de temps et d’organisation du travail. Ces différents résultats ont donné lieu à la création de supports pour les formateurs en apiculture. Les méthodes développées dans le cadre du projet peuvent par ailleurs être mobilisées pour l’appui aux apiculteurs ou futurs installés
Use of the WHO Access, Watch, and Reserve classification to define patterns of hospital antibiotic use (AWaRe) : an analysis of paediatric survey data from 56 countries
Background Improving the quality of hospital antibiotic use is a major goal of WHO's global action plan to combat antimicrobial resistance. The WHO Essential Medicines List Access, Watch, and Reserve (AWaRe) classification could facilitate simple stewardship interventions that are widely applicable globally. We aimed to present data on patterns of paediatric AWaRe antibiotic use that could be used for local and national stewardship interventions.
Methods 1-day point prevalence survey antibiotic prescription data were combined from two independent global networks: the Global Antimicrobial Resistance, Prescribing, and Efficacy in Neonates and Children and the Global Point Prevalence Survey on Antimicrobial Consumption and Resistance networks. We included hospital inpatients aged younger than 19 years receiving at least one antibiotic on the day of the survey. The WHO AWaRe classification was used to describe overall antibiotic use as assessed by the variation between use of Access, Watch, and Reserve antibiotics, for neonates and children and for the commonest clinical indications.
Findings Of the 23 572 patients included from 56 countries, 18305 were children (77.7%) and 5267 were neonates (22.3%). Access antibiotic use in children ranged from 7.8% (China) to 61.2% (Slovenia) of all antibiotic prescriptions. The use of Watch antibiotics in children was highest in Iran (77.3%) and lowest in Finland (23.0%). In neonates, Access antibiotic use was highest in Singapore (100.0%) and lowest in China (24.2%). Reserve antibiotic use was low in all countries. Major differences in clinical syndrome-specific patterns of AWaRe antibiotic use in lower respiratory tract infection and neonatal sepsis were observed between WHO regions and countries.
Interpretation There is substantial global variation in the proportion of AWaRe antibiotics used in hospitalised neonates and children. The AWaRe classification could potentially be used as a simple traffic light metric of appropriate antibiotic use. Future efforts should focus on developing and evaluating paediatric antibiotic stewardship programmes on the basis of the AWaRe index. Copyright (C) 2019 The Author(s). Published by Elsevier Ltd
