“…The stabilization time of about 2 min is required between the camera and the patient during the thermal measurements 35 . Skin temperature can be influenced by various factors, including prolonged exposure to specific environmental conditions such as extreme temperatures, humidity, and solar radiation, engaging in extended periods of physical activity 36 . The evaporation of moisture, such as sweat, on the skin's surface can have a significant impact on temperature measurements obtained by a thermal camera.…”

The study aimed to achieve the following objectives: (1) to perform the fusion of thermal and visible tongue images with various fusion rules of discrete wavelet transform (DWT) to classify diabetes and normal subjects; (2) to obtain the statistical features in the required region of interest from the tongue image before and after fusion; (3) to distinguish the healthy and diabetes using fused tongue images based on deep and machine learning algorithms. The study participants comprised of 80 normal subjects and age- and sex-matched 80 diabetes patients. The biochemical tests such as fasting glucose, postprandial, Hba1c are taken for all the participants. The visible and thermal tongue images are acquired using digital single lens reference camera and thermal infrared cameras, respectively. The digital and thermal tongue images are fused based on the wavelet transform method. Then Gray level co-occurrence matrix features are extracted individually from the visible, thermal, and fused tongue images. The machine learning classifiers and deep learning networks such as VGG16 and ResNet50 was used to classify the normal and diabetes mellitus. Image quality metrics are implemented to compare the classifiers’ performance before and after fusion. Support vector machine outperformed the machine learning classifiers, well after fusion with an accuracy of 88.12% compared to before the fusion process (Thermal-84.37%; Visible-63.1%). VGG16 produced the classification accuracy of 94.37% after fusion and attained 90.62% and 85% before fusion of individual thermal and visible tongue images, respectively. Therefore, this study results indicates that fused tongue images might be used as a non-contact elemental tool for pre-screening type II diabetes mellitus.

“…It has also been investigated that infrared temperature measurement using non-contact infrared thermometers underestimates body temperature, which may be insufficient to detect fever. There exist statistically significant correlations of infrared body temperature with outdoor temperature, relative humidity, and wind speed, which may trigger normal results in subjects who are truly febrile (29). That is, if an emergency patient is unaware of his low fever and visits the ED for non-febrile symptoms, the face recognition temperature measurement device may classify him in the range of normal body temperature when identifying and measuring his body temperature, leading him to enter the ED.…”

The current epidemic of Coronavirus Disease 2019 (COVID-19) has become a public health event worldwide. Through ethical analysis of a series of epidemic prevention phenomena and epidemic prevention measures taken by the Chinese (and other countries) government and medical institutions during the COVID-19 pandemic, this paper discusses a series of ethical difficulties in hospital emergency triage caused by the COVID-19, including the autonomy limitation of patients and waste of epidemic prevention resources due to over-triage, the safety problem of patients because of inaccurate feedback information from intelligent epidemic prevention technology, and conflicts between individual interests of patients and public interests due to the “strict” implementation of the pandemic prevention and control system. In addition, we also discuss the solution path and strategy of these ethical issues from the perspective of system design and implementation based on the Care Ethics theory.

“…Weather-related factors such as temperature, relative humidity, and wind velocity have also been found to be significantly correlated with patient body temperature, with effects varying in magnitude depending on the distances from outside to the measurement site (Spindel et al, 2021). For example, high environmental temperatures (above 99.5 °F) readily affect shell (skin) temperature and infrared thermometry measurements (Mei et al, 2021).…”

The Florida Undergraduate Research Association (FURA) is thrilled to partner with the Florida Gulf Coast University to launch the second edition of the Florida Undergraduate Research Journal (FURJ)! Helmed by Dr. Melodie Eichbauer along with a talented and committed Editorial Board, FURJ continues to be the first peer-reviewed undergraduate research journal composed of submissions from students across the state. FURA would like to offer special recognition to the authors whose research you will read about in the following pages, scholarship spanning across the disciplinary spectrum.Dissemination, or the sharing of research, is a crucial component of the overall research process. It is not sufficient to conduct our research, if we are not sharing it in ways that benefit the wider public. FURA has long supported undergraduate research sharing through the Florida Undergraduate Research Conference, one of the nation's largest multi-disciplinary research conferences that is open to all undergraduate researchers from any Florida higher education institution. The addition of the Florida Undergraduate Research Journal provides another significant way for undergraduate researchers across Florida to share their research with this wider community, stretching beyond the boundaries of their individual institutions. We are especially delighted to have created a permanent DOI for the journal, so the incredible work of these undergraduate researchers will remain easily accessible moving into the future.Again, congratulations to the student authors represented in our inaugural journal and a very special thank you to all those who volunteered their time to review submissions and craft this impressive feat. For those interested in joining the editorial board or submitting your own work in the coming year, please be sure to check out the FURJ page on our FURA website or follow FURA on any of our social media accounts. We also encourage you to review the great work published in 2022 in the inaugural edition of FURJ here. Happy reading!
