The German health-care system is characterized by a statutory health insurance based on the principle of social solidarity. Nonprofit sickness funds and regional associations of physicians are the central components of the German system. The historical development of the system for more than 100 years has been characterized by negotiations, rather than confrontation, among physicians, patients, and insurance carriers. With the increasing sophistication of modern medicine, medical expenditure is rising, and great demands are facing the health-care systems of the industrialized world. The hope is that the German system will be able to preserve the principle of solidarity and remain a one-tier health-care system rather than allow health care to be viewed as essentially a private consumption good, in which case availability and quality are allowed to vary with family income. As a means to achieve this goal, the autonomy of the sickness funds and regional associations of physicians will be increased substantially, and the governmental authority will be decreased. Strengthening of autonomy must be accompanied by incentives for self-responsibility and self-participation of Germany's citizens.  相似文献

The CALPHAD method is used for the thermodynamic assessment of the Cu-Ti system that bounds the ternary Cu-Ti-Zr system, which is capable of forming amorphous alloys. The self-consistent parameters of thermodynamic models of the phases are obtained from data on the phase equilibria and thermodynamic properties of liquid alloys and intermetallic compounds. The Gibbs energy of the liquid phase is described using the associated ideal solution model. To describe the thermodynamic properties of the Cu4Ti and CuTi intermetallic compounds with homogeneity range, sublattice models are used. The calculated phase diagram of the system and the thermodynamic properties of the phases are in good agreement with experimental data.  相似文献

The megakaryocytic apparatus of bone marrow and platelets are discussed as a common system whose physiological purpose is to ensure hemostasis when the integrity of the vascular wall is impaired. The principle of operation of the megakaryocyte-platelet system is synthesis, accumulation, and organization of a potent hemostatic potential, its distribution and dispersal along the vascular bed, if inactive, and its new formation at the moment of and at the site of required hemostasis. At the same time in its early and late major functional performance, the elements of the system are stable-at the early stages of megakaryocytopoiesis to the extent to the appearance of a promegakaryocyte and at the stage of platelet hemostatic cork. At the intermediate stages-that of the mature megakaryocyte divided by demarcation membranes and that of reversible aggregation of platelets which have not lost their individuality, the elements of the system are in an unstable state that is ready for disintegration or in a state that does not exclude its possibilities. In the central phase of its existence, the system is in a disintegrated state and appears as proplatelets and platelets. The mechanism of the dispersal and combination of elements and hemostatic potential of the megakaryocyte platelet system serves the apparatus of structural and contractile proteins, which acts as its system-forming factor.  相似文献

The RAND Corporation established a laboratory to conduct an interdisciplinary investigation of human factors in man-machine systems. RAND from 1951 to 1954 conducted a number of studies related to an Air Defense Direction Center (radar-site) concerning "a system that not only processes incoming information, but also makes crucial decisions based on interpretations of it." It was possible, on the basis of hypotheses generated and tested in the laboratory, to make some rather detailed predictions about system learning. A somewhat simplified schematic diagram of a system is presented. Various psychological skills important to STP (Systems Training Program) are briefly described. The "rapid growth of automation techniques presents a real challenge for psychologists, guaranteeing a most exciting future for those who care to meet it."
