the identification of available resources within a given geographic area, and coordination of services to meet the needs of a specific group of patients.

a system for providing appropriate care to all mothers and infants within a specific geographical region. Perinatal care may be provided at primary (Level I) , secondary (Level II), or tertiary (Level III or IV) centers depending on the risk status of mother and baby. The low-risk pregnancy can be managed at a primary center-a regular hospital delivery room and nursery, where basic emergency equipment and trained personnel are available if needed. A secondary center has trained staff and special equipment to care for a pregnant woman or for an infant with moderate problems. A tertiary, or third level, center has all the staff and technology needed to manage serious medical problems of the mother or infant. Intensive care nurseries are usually found in Level II, III or IV (tertiary) centers.

Procedure for subdividing a geographic area into regions of relative homogeneity in ecological systems or in relationship between organisms and their environment

Akima, Kriging and Inverse Distance Weighting are available for the regionalization of time-invariant and/or time-varying data in 1D and 2D for all initial conditions, boundary conditions and material parameters. The Database regionalization menu controls these functions (see User's Manual).

Countries generally have prohibited imports of a foreign agricultural product if it has been associated with an unwanted pest or disease in the exporting country. Until recently, importing countries would not permit any of that product from the exporting country, even if it came from a region that did not have the disease or pest. Regionalization is a fundamental principle in the Sanitary and Phytosanitary provisions of recent trade accords. It provides for the acceptance of such imports if the exporting country can demonstrate that they are from a disease-free or a pest-free area.
