The arterial system can be modelled by means of distributed analogs and by lumped parameter representations, such as the Windkessel. The distributed models, together with biological data, lead to the explanation of arterial function in terms of pressure and flow. The lumped parameter models form the basis of arterial compliance and characteristic impedance estimation. They also make comparison between mammals possible and it could be shown that input impedance, when scaled, is similar in mammals.

Medical informatics educational tasks seen from practical perspective. Tempus-Phare Project CME-02555-96.
This paper tries to synthesize the discussion of a seminar on medical informatics educational tasks held in May 1998 in Sinaia, Romania, within the frame of the Tempus-Phare Project CME-02555-96 entitled "Know How Transfer from University to Industry" and coordinated by the University of Medicine and Pharmacy Timisoara, Romania. Special emphasis was paid to particular features of medical education requirements in East European countries, with particular reference to Romania.

International experiences reveal the important role played by scientific research and systematic study a problems, in effectively tackling change in the health sector. Meta-analysis was introduced to address the problem of synthesizing the large quantity of information on a particular subject. It is viewed, only as a step in the process of developing better tools to quantify information across studies. ⋯ If there are gaps in the funnel shape it indicates that some studies may have not been published or located. In evaluating bias, we use meta-analysis studies about radiotherapy alone versus combined radiotherapy and chemotherapy in stages IIIa and IIIb non-small cell lung cancer. A simple analysis of funnel plots provides useful test for the likely presence of bias in meta-analyses, but as the capacity to detect bias will be limited when meta-analyses are based on a limited number of small trials the results from such analyses should be treated with considerable caution.

Knowledge optimization theory and application to point-of-care testing.
Point-of-care testing is defined as testing at or near the site of patient care wherever that medical care is needed. The number and types of tests available at the point of care are increasing dramatically. Point-of-care testing provides test results to the clinical team immediately, usually within a therapeutic turnaround time of five minutes. ⋯ The basis for optimality is improved medical and/or economic outcomes. Results show that point-of-care testing is strongly justified for emergency resuscitations under any circumstances, in critical care, such as the operating room and intensive care unit, and in disease management. Long-range implications are: (1) the point-of-care testing trend will accelerate; (2) viable optimization tools include integrative strategies, clinical algorithms, care paths, and performance maps; (3) attention should be focused on rapid communication and understanding of critical results; and (4) enhanced human interfaces are crucial for efficient medical decision making and efficacious patient therapy.

Telecommunications play an important role in telemedicine. Many forms of telecommunication services based on different telecommunication technologies are developed for various needs. The paper deals with complex real-time applications which demand high telecommunication requirements. ⋯ Requirements for multimedia elements are listed separately. Later on, short introduction of related telecommunication protocols is given. Real-time medical applications can show their ability in case of guaranteed quality of services delivered by telecommunication network as it is explained in the end.
