В спектре внутренней медицины гастроэнтерология является одной из наименее освещенных научными доказательствами областей. Это не означет, однако, что еe практика не может быть усовершенствована последовательным использованием подходов доказательной медицины
The perception of complex auditory information such as complete speech sequences develops during human ontogeny. In order to explore age differences in the auditory perception of predictable speech sequences we compared event-related potentials (ERPs) recorded in 5- to 6-yearold children (N = 15) and adults (N = 15) in response to anticipated speech sequences as successive and reverse digital series with randomly omitted digits. The ERPs obtained from the omitted digits significantly differed in the amplitude and latency of the N200 and P300 components between adults and children, the N400 and LPC components were more pronounced in children in the right frontal area for the digits presentation. These findings indicate that the perception of a successive speech structure is less automated in children and requires a detailed analysis of the successive structure and error detection. These differences in auditory ERPs reflect developmental changes in the auditory perception of speech sequences and can serve as indicators of the maturity of cognitive functions in children.
The study was aimed at examination of processing lexical-semantic information in Russian healthy individuals and aphasic patients grouped using aphasia diagnosis and lesion localization.
This prototype development explains the challenges encountered during the ISO/IEEE 11073 standard implementation process. The complexity of the standard and the consequent heavy requirements, which have not encouraged software engineers to adopt the standard. The developing complexity evaluation drives us to propose two possible implementation strategies that cover almost all possible use cases and eases handling the standard by non-expert users. The first one is focused on medical devices (MD) and proposes a low-memory and low-processor usage technique. It is based on message patterns that allow simple functions to generate ISO/IEEE 11073 messages and to process them easily. MD act as X73 agent. Second one is focused on more powerful device X73 manager, which do not have the MDs' memory and processor usage constraints. The protocol between Agent and Manager is point-to-point and we can distribute the functionality between devices.
Developed both implementation X73 Agent and Manager will cut developing time for applications based on ISO/EEE 11073.
