线性文本与超文本的区别,不只在于文本的结构方式、技术实现方式、阅读写作方式和存储记忆方式等方面,还在于文本的媒体表现方式.狭义的超文本,意指跨越文本局限、打破线性结构的语篇组织方式;广义的超文本,则是指运用超文本标示语言(HTML),经数字化编辑而成的包括文本、音乐、图像、动画、影视等一切表意媒体的信息集合(超文本语篇).因此,超文本连贯性,除了具有线性文本的特征,更有其自身的特点,以视觉原理为基础的数字化修辞手段便是主要手段之一. 相似文献

Recently, the digital imaging and communications in medicine (DICOM) standard introduced rules for the encoding, transmission,
and storage of the imaging diagnostic report. This medical document can be stored and communicated with the images in picture
archiving and communication system (PACS). It is a structured document that contains text with links to other data such as
images, waveforms, and spatial or temporal coordinates. Its structure, along with its wide use of coded information, enables
the semantic understanding of the data that is essential for the Electronic Healthcare Record deployment. In this article,
we present DICOM Structured Report (SR) and discuss its benefits. We show how SR enables efficient radiology workflow, improves
patient care, optimizes reimbursement, and enhances the radiology ergonomic working conditions. As structured input significantly
alters the interpretation process, understanding all its benefits is necessary to support the change.

The present paper proposes a new psychophysiological approach to the genesis of positive and negative schizophrenic symptoms. According to this approach, the initial factor in schizophrenic disorders is a functional insufficiency of the right hemisphere which can be determined by early emotional experience in combination with subtle brain damage. This functional insufficiency causes (a) the inability to grasp and select information before its realization; and (b) the inability to produce a polysemantic context which is crucial for creativity, psychological defense, and the restoration of search activity, all of which determine psychophysiological adaptation to the environment. Right hemisphere insufficiency causes left hemisphere hyperactivity as an ineffective attempt to compensate for this functional deficiency. As a result, normal search activity is replaced by artificial search activity which is represented by “positive” symptoms, and which uses the predisposition of the left hemisphere's catecholamine system for its increased activity. The suggestion is made that cognitive impairment in schizophrenia (the inability to use appropriate previous information in relation to current perceptual input) is related to the competition between information processing which requires left hemisphere activity, and the formation of positive symptoms, also based on left hemisphere activity. 相似文献

Based on the fuzzy characteristic of the pulse state and syndromes differentiation thinking mode of TCM, an information fusing recognition method of pulse states based on SFNN (Stochastic Fuzzy Neural Network) is presented in this paper. With the learning ability in parameters and structure, SFNN fuses the measurement information of three pulse-state sensors distributed in Cun, Guan, and Chi location of body for the pulse state recognition. The experimental results show that the percentage of correct recognition with new method is higher than that by single-data recognition one, with fewer off-line train numbers. 相似文献

This study uses the Taiwan Healthcare Indicator Series (THIS) system as an example to examine which determinants would improve
performance by sharing indicators from a management perspective. This study population included all 227 hospitals participating
in the THIS system in 2006. A structured questionnaire was sent to the director who was responsible for the THIS system via
electronic mail. A total of 111 responses were returned by February 10, 2006. Questions included current implementation and
impacts of the system. Hierarchical regression models were performed to identify which variables were significantly associated
with performance improvement, adjusted for hospital characteristics. Four variables significantly associated with implementing
the THIS system to improve performance were ‘senior management support,’ ‘benchmarking,’ ‘making departments improve the underperforming
indicators and report the improvement results in performance management meetings,’ and ‘integration with the National Health
Insurance payment regulations’. This study contributes substantially to the evidence base about what works to improve performance
by information sharing. Although information sharing is the basis of efforts to improve performance, senior management support
and how to effectively apply the information are the most important determinants of performance enhancement. 相似文献
