This study extends our knowledge on the role of informal caregivers of seniors and the impact of this role on presenteeism and absenteeism at work. Based on the conservation of resources theory, this article seeks to gain insights into the mechanisms and antecedents of presenteeism and absenteeism among employees who are also informal caregivers of seniors. Specifically, this article argues that family-work conflict and emotional exhaustion mediate the relationship between the informal caregiver's role, presenteeism, and absenteeism.

This article aims to analyse the integration of sex and gender (s/g) by ergonomics students during their internship at the master's degree level, following training sessions on s/g issues in the workplace. This exploratory research used a descriptive mixed-methods design, encompassing evaluation of students' intention to use the content from the training ( = 13 students), and a multiple case study ( = 5 ergonomics interventions). The results show that while students found the training relevant, they only minimally integrated s/g in their interventions and when they did, it was primarily from an anthropometric and physiological perspective.

A Spectral-Based Approach for BCG Signal Content Classification.

Sensors (Basel)

February 2021

Laboratoire de Recherche en Imagerie et en Orthopédie, CRCHUM, Montreal, QC H2X 0A9, Canada.

This paper has two objectives: the first is to generate two binary flags to indicate useful frames permitting the measurement of cardiac and respiratory rates from Ballistocardiogram (BCG) signals-in fact, human body activities during measurements can disturb the BCG signal content, leading to difficulties in vital sign measurement; the second objective is to achieve refined BCG signal segmentation according to these activities. The proposed framework makes use of two approaches: an unsupervised classification based on the Gaussian Mixture Model (GMM) and a supervised classification based on K-Nearest Neighbors (KNN). Both of these approaches consider two spectral features, namely the Spectral Flatness Measure (SFM) and Spectral Centroid (SC), determined during the feature extraction step.

Spatio-Temporal Abnormal Behavior Prediction in Elderly Persons Using Deep Learning Models.

Sensors (Basel)

April 2020

LICEF Research Institute, Department of Science and Technology, TELUQ University, Montreal, QC 11290, Canada.

The ability to identify and accurately predict abnormal behavior is important for health monitoring systems in smart environments. Specifically, for elderly persons wishing to maintain their independence and comfort in their living spaces, abnormal behaviors observed during activities of daily living are a good indicator that the person is more likely to have health and behavioral problems that need intervention and assistance. In this paper, we investigate a variety of deep learning models such as Long Short Term Memory (LSTM), Convolutional Neural Network (CNN), CNN-LSTM and Autoencoder-CNN-LSTM for identifying and accurately predicting the abnormal behaviors of elderly people.

An analysis of 3D knee kinematic data complexity in knee osteoarthritis and asymptomatic controls.

PLoS One

March 2019

Laboratoire de recherche en imagerie et orthopédie, Centre de recherche du CHUM, École de technologie supérieure, 900 Rue Saint-Denis, Montreal (QC), H2X 0A9, Canada.

Three-dimensional (3D) knee kinematic data, measuring flexion/extension, abduction/adduction, and internal/external rotation angle variations during locomotion, provide essential information to diagnose, classify, and treat musculoskeletal knee pathologies. However, and so across genders, the curse of dimensionality, intra-class high variability, and inter-class proximity make this data usually difficult to interpret, particularly in tasks such as knee pathology classification. The purpose of this study is to use data complexity analysis to get some insight into this difficulty.
