RÉSUMÉ

The aging population and the increasing prevalence of chronic diseases in the elderly have brought a significant economic burden to families and society. The non-invasive wearable sensing system can continuously and real-time monitor important physiological signs of the human body and evaluate health status. In addition, it can provide efficient and convenient information feedback, thereby reducing the health risks caused by chronic diseases in the elderly. A wearable system for detecting physiological and behavioral signals was developed in this study. We explored the design of flexible wearable sensing technology and its application in sensing systems. The wearable system included smart hats, smart clothes, smart gloves, and smart insoles, achieving long-term continuous monitoring of physiological and motion signals. The performance of the system was verified, and the new sensing system was compared with commercial equipment. The evaluation results demonstrated that the proposed system presented a comparable performance with the existing system. In summary, the proposed flexible sensor system provides an accurate, detachable, expandable, user-friendly and comfortable solution for physiological and motion signal monitoring. It is expected to be used in remote healthcare monitoring and provide personalized information monitoring, disease prediction, and diagnosis for doctors/patients.

RÉSUMÉ

Objective: To explore the effect of emotional optimization of workplace employees in immersive virtual natural environment. Methods: In July 2020, 15 subjects were selected to complete two groups of treadmill walking training experiments in virtual natural environment and daily environment respectively. At the same time, the subjects' skin electrical (EDA) , pulse frequency (Pf) , respiratory frequency (Rf) physiological data and Self-Assessment Manikin (SAM) data before and after walking were collected; the mean value of three dimensions of SAM and the emotion difference before and after the experiment were calculated. The differences of physiological indexes and subjective mood changes of subjects were tested by paired sample t-test. Results: Compared with the daily environment, the ΔEDA, ΔPf and ΔRf of the subjects in the virtual natural environment were all decreased , and the differences were statistically significant (P<0.05). There were statistically significant differences in pleasure and arousal between subjects before and after using the virtual natural environment (P <0.05). Compared with the daily environment, the Δpleasure degree of subjects using the virtual natural environment increased, and the Δarousal degree and Δdominance degree decreased, and the differences were statistically significant (P <0.05). Conclusion: Walking in virtual natural environment can help subjects improve their mood, relax and improve the regulation ability of autonomic nervous system.

RÉSUMÉ

Objective: To compare l-Borneolum, Borneolum, Borneolum Syntheticum, Styrax, and Benzoinum for regulating the physiological index of node and strength in a rat model of lipopolysaccharide (LPS)-induced fever in parallel based on the overall concept of tradition Chinese medicine (TCM) and the idea of dynamic view. Methods: The influence of resuscitation inducing aromatic herbs on rats with normal activities of body temperature (T), heart rate (HR), blood pressure (SBP and DBP), activity (A), and other physiological parameters were dynamically monitored by DSI implantable physiological signal telemetry technology. The data were processed and mapped by SPSS 17.0, SAS 9.2, and OriginPro 8.5. Results: Three kinds of borneol showed inhibitory effect on T and HR of model rats, and l-Borneolum had the optimal inhibitory effect; Styrax showed the excitation-inhibition trend on HR, SBP, DBP, and A of model rats; Benzoinum had no obvious effect on each index. The results of principal component analysis showed that Borneolum and Styrax had the same orientation in model rats; Borneolum Syntheticum could simultaneously affect A, SBP, and DBP. Cluster analysis and correspondence analysis showed that characteristics of three kinds of borneol can be classified as the same kind; Benzoinum and Styrax had their own affect rules. Conclusion: The three kinds of drugs have inhibitory effect on each physiological index; Styrax has the excitation-inhibition trend, which is related to the previous understanding of its time-window; Benzoinum has no effect on model rats, which is related to its evenness. The future research can be expanded on the mechanism of resuscitation drugs on rats with LPS-induced fever.
