Intelligent beehive monitoring system based on internet of things and colony state analysis
Published 2024-12-01“…With the development of the IoT and computer vision algorithms, we hope to provide an automated and efficient system to meet the above challenges. In this paper, we proposed a hive monitoring system, and build a visualization module in the cloud to monitor the activity of bee colonies and the environmental dynamic changes. (1) We proposed a multi-bee tracking algorithm to solve the problem of monitoring bees at the door of the hive; (2) we constructed a dataset containing various complex scenes, named BEE22, for training and testing the performance of our algorithm; (3) we designed a bee counting rule, based on results of multi-bee tracking algorithm, to reasonably count the bees entering or leaving the beehive; (4) we have deployed multiple sensors around(center, margin, door, and environment) the hive to accurately reflect the changes in the environment around the hive. …”

“The Heart of the Center”: Exploring the Role of the Patient Care Technician in US Dialysis Care
Published 2025-01-01“…Eight themes emerged: (1) value of PCT role is not reflected in job or organizational policies and structures; (2) PCTs play a flexible and often ill-defined role in dialysis clinics; (3) despite being in a position with high risk of burnout, PCTs find ways to persevere and provide high-quality care; (4) PCTs are often perceived as “helpers” or ancillary rather than an integral part of the dialysis care team; (5) PCT job training and qualifications are not standardized and often not commensurate with job expectations and responsibilities; (6) PCT-patient relationships are deeply valued, but boundaries can be fluid and become blurred because of the frequency and nature of dialysis care; (7) dialysis patients and staff are vulnerable to multilevel workplace safety issues; and (8) PCT-staff dynamics have a strong impact on employee morale, clinic efficiency, and patient satisfaction. …”
