Burnout and job stress are tragic events that unfortunately occur in many professions. In the teaching profession, however, it affects not just the individual, but also several concomitant parties: students, school, and parents. This has lead to the widespread problem of teacher attrition, where the challenge has become not so much to attract teachers, but to retain them. The present research is based on the reflective writing of early career teachers (ECTs). These ECTs volunteered to write short weekly reflections during a period of about half a year. Spotting potential wellbeing problems in these series of reflections, however, calls for careful reading and studying of such large amounts of texts that manual processing became impracticable. Hence, we developed an algorithm which transforms such a stream of reflections into a 3-D visualization of mood changes, in which times of stress and potential for burnout can be detected more easily. This in turns makes it possible to notice points of concern when there is still time to intervene. Copyright © 2022 by SCITEPRESS – Science and Technology Publications, Lda. All rights reserved.

作者： Fekete, Jean-Daniel Freire, Juliana INRIA Saclay Ile De France France NYU Comp Sci & Engn & Data Sci New York NY USA NYU Visualizat Imaging & Data Anal VIDA Ctr New York NY USA

The American National Academies of Sciences, Engineering, and Medicine (NASEM) has recently released the report "Reproducibility and Replicability in Science." The report has prompted discussions within many disciplines about the extent of the current adoption of reproducibility and replicability, the challenges involved in publishing reproducible results as well as strategies for improving. We organized a panel at the IEEE VIS conference 2019 to start a discussion on the reproducibility challenges faced by the visualization community and how those challenges might be addressed. In this viewpoint, we summarize key findings of the NASEM report, the panel discussion, and outline a set of recommendations for the visualization community.

Brain tumors are complex and potentially life-threatening conditions requiring accurate diagnosis. This study explores using VGG16 CNN architecture to classify brain tumors in MRI scans. CNNs excel in image classification but lack transparency, raising concerns in critical applications like medical diagnosis. To address this, we use Explainable AI (XAI) techniques. We enhance interpretability using Superpixel images, Heatmaps, and Image Masks to visualize important features for predictions. Our approach achieves 98.8% accuracy, with visualizations aiding in understanding the model’s decisions and providing insights for medical professionals. This research contributes to XAI in medical imaging, showing the potential of combining deep learning with interpretable methods for healthcare decision-making.

Third-dimensional human anatomical models have been used to better understand the human body. However, one of their most important uses is the personalization of any type of treatment. 3D human models of bones from the lower extremities are crucial for visualization, treatment planning, and orthotic and prosthetic design. Nonetheless, this 3D models must be compatibles with any modeling software, like those working with the finite element method. Therefore, a methodology to generate 3D anatomical models compatible with CAD systems was proposed. A couple of sets of Computed Tomography (CT) images in DICOM (Digital imaging and Communications in Medicine) format was used. To reduce the computational cost, different optimization algorithms were implemented. A Gaussian low-pass filter was implemented for bone segmentation, and the thresholding method was applied. Morphological operations to eliminate sparse pixels, gaps and to generate smooth edges were performed. The Marching Cubes algorithm was used to generate a three-dimensional mesh. The 3D model scale was adjusted by the metadata in the DICOM files. The 3D model surfaces were smoothed by a Gaussian filter applied to the segmented images and an averaging filter used on the model’s vertices. To verify the dimensions of the reconstructed model, they were compared with those obtained from a model reconstructed in InVesalius 3.1. Approximately, it took 1.95 min to generate the exported 3D model in a CAD-compatible STL file. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Clinical procedures rely heavily on visual data, particularly in diagnostic radiology. Eye-tracking technology was employed in this study to examine the relationship between visual search features and diagnostic performance in capsule endoscopy. Conventional visual search models, developed for static 2D images, may not be suitable for cross-sectional stack imaging used in computed tomography (CT) and magnetic resonance imaging (MRI) due to their dynamic nature. The study aimed to address this gap by analyzing the visual search patterns of an expert examining capsule endoscopy images. A framework integrating an eye tracker was developed, and a dataset of 536 images was collected. The eye-tracking system showed high accuracy in capturing gaze data. Expert visual search patterns were found to follow predominantly circular trajectories, with distinct optical flow characteristics. Variations in fixation duration and location were noted, with certain image types exhibiting drilling and scanning patterns. These findings highlight the potential for using eye-tracking data to improve diagnostic accuracy and contribute to radiology education.

This research delves into the intricate relationship between emotions and mental health, acknowledging the profound impact of emotional states on critical aspects such as task-solving ability, concentration, judgment, behavior, and overall daily functioning. Leveraging three distinct approaches to the study of emotions-self-reporting, analysis of nonverbal cues, and physiological assessments-seeking to provide a comprehensive understanding of the complex interplay of emotions in human experiences. Emotion recognition traditionally relies on tracking facial and bodily cues, but the concealment of true emotions remains a challenge for individuals adept at masking their feelings. To address this limitation, our study proposes a novel approach using thermal imaging, capitalizing on the inherent physiological changes in humans during emotional experiences. This research will use VGG16 and EfficientNet to analyze human emotions through thermal image, video, and camera.

This paper uses a new visualization method. The goal is to improve the results of 3D image reconstruction. Firstly, the hardware architecture of the system is improved. The clock of the system is extended. The combination of CY25400 micro controller and CDCVF2510 micro controller greatly speeds up the detection speed. Then the key technologies such as image parsing module, image preprocessing module and 3D visualization module are studied. The visualization elements are fed back to the 3D image to realize virtual reconstruction. Finally, the conventional 3D imaging technology is used to complete the simulation and comparison test in the same scene. Experiments show that this method can obtain high 3D image reconstruction effect. The system can clearly show the edge area of the image, and can meet the requirements of users.
