Why Do You Wear A Mask? Children’S Conceptualizations Of Covid-19 And Contagion Avoidance Behaviors, Emily Hillman

Scripps Senior Theses

With the outbreak of the COVID-19 pandemic, a need has emerged for psychological research on children’s understanding of infectious disease transmission. However, little existing research examines the link between children’s cognitive reasoning about illness and their subsequent behaviors regarding its transmissibility. This study will examine children’s conceptualizations of contagious illnesses such as COVID-19 and their subsequent contagion avoidance. A mixed methods approach will be used to establish the content of children’s conceptualizations of contagion and level of causal reasoning related to illness transmission. Dyads will be constructed comprising 4-12-year-old children and their parents. It is expected that parental contagion avoidance …

Evaluation Of Test Methods For Determining Footwear Slip Resistance On Ice Surfaces, Chantal Gauvin, Atena Roshan Fekr, Yue Li, Gordon Wong, Wayne Cheng, David Pearsall, Tilak Dutta

Rapports de recherche scientifique

Slipping on ice is one of the main risks of outdoor occupational activities during winter. Ice and freezing rain were involved in 14% of slip, trip and fall (STF) accidents from 2014 to 2016 in Quebec. Many workers who perform outdoor activities rely on their boots to prevent them from slipping. However, choosing the best slip resistant footwear is challenging. Currently, there is no standard test method for evaluating slip resistance of footwear on ice surfaces. The SATRA STM 603 whole shoe tester is used in standard test methods (ASTM International, 2019b, F2913-19; International Organization for Standardization [ISO], 2019, 13287:2019) …

Confort Thermique Et Mobilité Des Policiers Motards Lors Du Port Du Gilet Pare-Balles : Une Analyse Ergonomique, Steve Vezeau, Alain S. Comtois, Victoria Budico

Rapports de recherche scientifique

Plusieurs études démontrent une diminution importante des risques de décès chez les agents de police qui portent un gilet pare-balles (GPB). Cependant, certains patrouilleurs demeurent réticents à le revêtir à cause des inconforts qu’il engendre sur les plans thermiques et de la mobilité; ceux-ci représentent 8 % de l’ensemble des agents de police et 47 % des agents motards, ce qui accroît les risques pour leur sécurité. Les agents des unités motocyclistes seraient donc parmi les plus exposés, notamment en raison de conditions particulières telles que le travail à l’extérieur, la proximité d’une source de chaleur (moteur), le port de …

Mise Au Point D’Une Méthode De Mesure Objective De L’Effet D’Occlusion Basée Sur La Voix, Hugues Nélisse, Hugo Saint-Gaudens, Franck Sgard, Olivier Doutres

Rapports de recherche scientifique

Lors de l’utilisation de protecteurs auditifs ou de prothèses auditives, le fait d’obstruer le canal auditif peut engendrer un effet indésirable et désagréable, appelé « effet d’occlusion », qui se manifeste notamment par la sensation que notre propre voix sonne différemment, avec de basses fréquences amplifiées, qu’elle est distordue. L’effet d’occlusion est souvent considéré comme une source d’inconfort qui entraîne parfois les utilisateurs de protecteurs ou de prothèses à mal les utiliser ou encore à simplement les retirer. Dans le cas des travailleurs, par exemple, le retrait des protecteurs auditifs peut les exposer à des niveaux de bruits potentiellement dangereux, …

Particular Matter with diameter <2.5 microns or micrometers (a pollutant PM2.5) is highlighted as dangerous kind of pollutant in the worldwide. There were epidemiological studies reporting the harmful effects of PM2.5 in population due to the particle can lead various chronic diseases and premature deaths. The aim of this study is to assess the changes in health due to short- and long-term exposure and to provide the estimation attributed cases and proportion in the Thai population which could be avoid where the PM2.5 concentration reduce to the cut-off values that respected I collected data of PM2.5 concentration from 70 air monitoring stations of Pollution Department Control Thailand to indicate all provinces. For missing data, the values were calculated using the single imputation technique. The Ordinary Kriging Techniques were applied to construct the interpolations of PM2.5 concentration data for each district. I collected national health data including total number morbidity and mortality incidences related with negative effects from PM2.5 exposure in all provinces from Ministry of Public Health, Thailand. Total numbers of population all ages for specific province have been collected, where people ages >30 years old as population at risk on this study. This study presents all data that collected in 2019.

Leakage Versus Material Filtration In Barrier Facemask Efficiency, Ali Bahloul, Clothilde Brochot, Barbara Layne

Études primaires

The World Health Association and many governmental agencies recommend the wearing of facemasks by the general public to prevent the spread of COVID-19. It is believed that masks can significantly protect others and may offer some protection to the wearer. Although there are standards for FFRs, surgical masks, and recently for barrier face coverings, they all indicate the level of protection for the wearer. However, testing facial masks not at the point of inhalation, but at the source, the exhale, offers a new perspective on how to impede particle emissions. In this paper, the experimental results show that, although the …
