OBJECTIVE To assess delay in clinicians obtaining emergency biochemistry test results when the telephoning of results by laboratory staff is supplanted by installation of computer ward terminals. DESIGN Retrospective observational study. SETTING Accident and emergency department and acute medical admissions ward of a teaching hospital. SAMPLE 3228 emergency requests for biochemistry tests...

IN THE cognitive domain mathematics provides one of the clearest examples of complex learning and performance, for the structure of the subject itself provides numerous constraints on any adequate theory. The learning and performance models derived from the main trends of contemporary mathematical learning theory have provided an excellent predictive analysis of a large variety of experimental ...

Many phylogenetic analyses, particularly morphological studies, use higher taxa (e.g., genera, families) rather than species as terminal taxa. This general approach requires dealing with interspecific variation among the species that make up the higher taxon. In this paper, I review different parsimony methods for coding and sampling higher taxa and compare their relative accuracies using compu...

Intermodal terminals are critical elements in the total freight transportation chain. They provide the interface not only between modes, but also between shippers and carriers. Therefore, the performance of those terminals needs to be closely monitored and their operations optimised with respect to the two key performance areas, namely: customer service and operational efficiency. This paper de...

The integrated telemonitoring system (ITS) for homecare has been designed to improve quality of care as measured by increased nursing productivity, improved patients' clinical and behavioral outcomes and reduction of cost. The system incorporates managerial, organizational, operational and clinical tasks optimized for delivery of quality care through telemonitoring. A secure, multi-modal comput...

We present a unified polynomial-time approximation scheme (PTAS) for the prize collecting traveling salesman problem (PCTSP) and the prize collecting Steiner tree problem (PCSTP) in doubling metrics. Given a metric space and a penalty function on a subset of points known as terminals, a solution is a subgraph on points in the metric space, whose cost is the weight of its edges plus the penalty ...

applications are mobile communication terminals, digital consumer equipment, and multimedia systems. One example of digital consumer equipment is the digital still camera. Hitachi has developed a digital camera system based on the SH-DSP (Fig. 1). ABSTRACT: Recently sales have grown markedly in the field of mobile communication terminals such as global system for mobile communications (GSM), pe...

The evolution of the mobile communication systems is paving the way towards the development of new information services. At present Location Based Services (LBS) are gaining momentum since they allow the provision of mobile users with information related at their positions that, therefore, can help them on the move. The access to an information system is complicated by the fact that the access ...

Computer technology today only provides modest support for mobile users: small and lightweight `Personal Digital Assistants' are available but are limited to proprietary user interfaces; in particular they lack adequate input facilities. Notebook computers feature standard keyboards but these limit miniaturisation and therefore mobility. Both PDAs and notebook computers suffer from current defi...

in this paper, we are going to investigate the growth of the iranian maritime transport with a focus mainly on the north - south transit corridor, review of dry ports in order to support the iranian container terminals at the south ports in order to increase the volume of container storages at the terminals. for the purpose of assessing the outcome of port operational management, the balanced s...
