Among these, SOC10 emergedas the symptom with the highest intensity, centrality, and proximity, identifying it as the most central symptom.CONCLUSIONThe network model has strong explanatory power in describing the psychological consistency symptoms ofpatients after PCI, identifying the central SOC symptoms, among which SOC10 is the key to overall SOCenhancement, and there is a strong positive correlation between SOC2 and SOC8, emphasizing the need to considerthe synergistic effect of symptoms in intervention measures.展开更多

The non-dimensional symptom parameters in time domain are defined for reflecting the features of time signals measured for the fault diagnosis of rotating machinery. The synthetic detection index is also proposed to evaluate the sensitivity of non-dimensional symptom parameters for detecting faults. The practical example of condition diagnosis for detecting and distinguishing fault states of a centrifugal pump system, such as cavitation, impeller eccentricity which often occur in a centrifugal pump system, are shown to verify the efficiency of the method proposed in this paper.展开更多

Sixty-eight patients diagnosed with cancer participated in the research, with ages varying between 25 and 83 years (A = 55.4;SD = 13.3) and 85.3% were female. The instruments used were Identification Questionnaire, Perceived Social Support Scale—adult version (EPSUS-A), Medical Outcomes Short-Form Health Survey (SF-36) and the Baptista Depression Scale Hospital—clinic version (EBADEP-HOSP-AMB). It was verified that most of the patients reported not having depression diagnosis before the cancer, nor in the current moment, besides not using anti-depressive medication. The scores obtained in the EBADEP-HOSP-AMB suggest light depressive symptoms. It is concluded that the depressive symptoms were mostly presented in women, in patients with worse mental health condition and in those less satisfied with the social support.展开更多
