Tatouage des Images Médicales en Vue d'Intégrité et de Confidentialité des Données
2010
International audience; Dans l'objectif de contribuer à la sécurité de partage et de transfert des images médicales, nous présentons dans ce travail la méthode de tatouage multicouche. Cette dernière consiste à insérer dans l'image médicale les informations qui concernent la signature de centre hospitalier et les données du patient. Elle doit permettre d'assuré l'intégrité, la confidentialité des données lors de leur partage, et la robustesse aux différents types d'attaques (compression JPEG, Copier-coller, transformations géométriques, etc).
Analysis of the perceived self-‐efficacy in the use of ICT of pre-‐ service primary and preschool teachers
2017
La formación del profesorado en el uso de las TIC es un aspecto importante para conseguir una verdadera integración de las TIC en la educación. Según el modelo TPACK, esta formación no debe limitarse a contemplar de manera separada los aspectos relacionados con las TIC, el contenido curricular y la metodología. En el presente estudio se explora la percepción de autoeficacia en cuanto al uso de las TIC en el aula de una muestra de 107 estudiantes de los grados de Maestro/a en Educación Infantil y en Educación Primaria. Para ello se emplea una traducción del cuestionario para la autoevaluación de las competencias TIC elaborado por Tondeur et al. (2016). Los resultados del estudio muestran que…
Frazeologizmy w internetowych grach werbalno-wizualnych
2021
Obraz zdominował nasze życie, stał się jego nieodłącznym elementem, wdziera się do niego z ekranów telewizorów, telefonów, komputerów. Użytkownicy internetu korzystają z możliwości, jakie daje im komputer, i chętnie tworzą teksty łączące w sobie elementy werbalne i graficzne. Jednym z najpopularniejszych polikodowych gatunków internetowych są demotywatory. Połączenie w nich dwóch kanałów: werbalnego i ikonicznego powoduje wzmocnienie siły ich oddziaływania. Często w werbalnej części demotywatorów są wykorzystywane frazeologizmy i skrzydlate słowa. Połączenie ich z elementem graficznym powoduje ich defrazeologizację oraz grę językową z wykorzystaniem wieloznaczności i homonimiczności wyrazów.
"Last Signification Bits" Method for Watermarking of Medical Image
2011
International audience; In this paper, we present a new approach for watermarking of medical image that we are trying to adapt to telemedicine. This approach is intended to insert a set of data in a medical image. These data should be imperceptible and robust to various attacks. It's containing the signature of the original image, the data specific to the patient and his diagnostic. The purpose of the watermarking method is to check the integrity and preservation of the confidentiality of patient data in a network sharing. This approach is based on the use the LSB (least significant bits) of the image and tools borrowed from cryptography.
Näkyvä lapsuus : lapsuuskuva havainnointipäiväkirjassa ja television mainoskuvissa
2017
This research addresses images of childhood in the context of media and children´s everyday lives. Images of childhood reproduced by young children themselves and by their parents and day-care personnel, and in television advertising were investigated. Representations are studied as social, cultural and historical entities that are formed in the course of everyday life. The question is asked, what kind of childhood is (re)produced in children's everyday lives and in the media context, and how are the representations created using visual and textual materials connected with the cultural imagery of childhood? To collect child observations and descriptions of daily lives as provided by adults …
On Temporal Aspects in Cross-Cultural e-Collaboration Between Finland and Japan Research Teams
2018
Time is an essential dimension in cross-cultural e-collaboration among research project teams. Understanding temporal aspects and project dynamics in cross-cultural research e-collaboration and related processes can improve team members' skills in cross-cultural communication and increase their cultural competence. The present case cultures are Finnish and Japanese, and the case universities are the University of Jyväskylä (Finland) and Keio University (Japan). Three issues are addressed in this article. First, cultural dimensions and time models in the cross-cultural e-collaboration context are discussed. Second, temporal aspects related to e-collaboration activities are introduced. Third,…
Caractérisation fine du climat en serre expérimentale - Cas de la plateforme 4PMI de l’INRA de Dijon
2019
Les conditions environnementales dans lesquelles sont cultivées les plantes influent grandement surleurs caractéristiques observables, i.e. leur phénotype. Les conditions environnementales d’une serren’étant pas homogènes, elles peuvent induire un biais lors de l’analyse des résultats de phénotypage.Afin de mieux contrôler ce biais, la plateforme « Plant Phenotyping Platform for Plant Micro-organismsInteractions » (4PMI) hébergée par le Centre INRA de Dijon a mis en place un système decaractérisation du climat de chaque plante dans ses serres. Le développement de ce protocole a faitl’objet de ce stage. Dans un premier temps un système de collecte et de gestion des donnéesclimatiques produit…
High-Frequency and Ultra-High Frequency Ultrasound: Musculoskeletal Imaging up to 70 MHz
2020
AbstractMusculoskeletal (MSK) ultrasound has well-established advantages, able to investigate very small structures with high resolution and a quick and real-time dynamic evaluation with the possibility of contralateral comparison. Thus ultrasound has kept its own almost exclusive fields of application in daily clinical practice, and it is considered the first-level imaging technique to assess tendons, bursae, and capsuloligamentous structures of small peripheral joints as well as peripheral nerves. Up to now, however, clinical MSK ultrasound imaging could not go beyond the first 1 to 2 cm under the skin, using high-frequency probes up to 18 to 20 MHz with spatial resolution just below mill…
FRIGHTENING OF CHILDREN BY PARENTS AND ITS CONSEQUENCES
2018
The article attempts to generalize data on such a complex pedagogical and psychological phenomenon as the deliberate frightening of children by adults. Despite an obvious or apparent harm, it is still included in the established set of methods of family education. In our study, we studied the origins of this phenomenon, the degree of its prevalence in the practice of family education at the present time, and the consequences of using threats in the process of education in the assessments of the adults who were brought up in this way.To achieve the research objectives, a number of former children who were frightened in childhood by their parents, the content of adults’ threats, the motives f…
