objectives : the present study was designed to investigate the possible relationship between job stress and mental health in a group of hospital employees of shiraz university of medical sciences. method: three hundred and ninety-seven employees (150 administrative and 247 medical staff) were selected randomly through stratified random sampling. they were requested to answer the general health ...

Multilevel inverters in renewable applications usually require a high-voltage dc link fed by front-end dc--dc boost stage. Such two-stage power conversion, however, increases the switch count, leading to higher costs and losses. To lower number of switches, this letter proposes six-switch inverter, capable generating seven-level voltage triple-voltage boost. Both features are achieved with only...

Healthcare applications are complex in the way data and schemas are organised in their internal systems. Widely deployed healthcare standards like Health Level Seven (HL7) V2 are designed using flexible schemas which allow several choices when constructing clinical messages. The recently emerged HL7 V3 has a centrally consistent information model that controls terminologies and concepts shared ...

Different communication standards in healthcare esp. HL7 version 2.x [1] and v3 [2] lack interand intra-family compatibility. Bridging between those to establish semantic interoperability using a formal ontology as a mediator in a mapping process [3] has demonstrated that both communication standards have in principle the same underlying architecture. This paper shortly analyses this structure ...

OBJECTIVE Biomedical research increasingly relies on the integration of information from multiple heterogeneous data sources. Despite the fact that structural and terminological aspects of interoperability are interdependent and rely on a common set of requirements, current efforts typically address them in isolation. We propose a unified ontology-based knowledge framework to facilitate interop...

Secure and scalable data sharing is essential for collaborative clinical decision making in telemedicine. Conventional clinical data efforts are often siloed, however, which creates barriers to efficient information exchange and impedes effective treatment decision making for remote patients. This paper provides four contributions to the study of applying blockchain technology to clinical data ...
