| medical records, problem-oriented | The structuring of a patient's record according to a complete listing of his medical problems accompanied by progress notes for each problem. (12 Dec 1998) |
|---|---|
| problem | 1. A question proposed for solution; a matter stated for examination or proof; hence, a matter difficult of solution or settlement; a doubtful case; a question involving doubt. 2. <mathematics> Anything which is required to be done; as, in geometry, to bisect a line, to draw a perpendicular; or, in algebra, to find an unknown quantity. Problem differs from theorem in this, that a problem is something to be done, as to bisect a triangle, to describe a circle, etc.; a theorem is something to be proved, as that all the angles of a triangle are equal to two right angles. <geometry> Plane problem, a problem requiring in its geometric solution the use of a conic section or higher curve. Origin: F. Probleme, L. Problema, fr. Gr. Anything thrown forward, a question proposed for solution, fr. To throw or lay before; before, forward + to throw. Cf. Parable.

| problem area wetland | <ecology> A wetland that is difficult to identify because it may lack indicators of wetland hydrology and/or hydric soils, or its dominant plant species are more common of nonwetlands. (09 Oct 1997) |
| problem-based learning | Instructional use of examples or cases to teach using problem-solving skills and critical thinking. (12 Dec 1998) |
| problem-oriented record | A system of record keeping in which a list of the patient's problems is made and all history, physical findings, laboratory data, etc. Pertinent to each problem are placed under that heading; especially useful for out-patient records of patients with multiple problems who are followed for long periods. (05 Mar 2000) |
| problem solving | A learning situation involving more than one alternative from which a selection is made in order to attain a specific goal. (12 Dec 1998) |
| Sturm-Liouville problem | <radiobiology> The general problem of solving a linear differential equation of order 2n, together with 2n boundary conditions, also known as the eigenvalue problem. (09 Oct 1997) |
| French flag problem | The French flag (tricolour) is used to illustrate a problem in the determination of pattern in a tissue, that of specifying three sharp bands of cells with discrete properties that do not have blurred edges using, for example: a gradient of a diffusible morphogen. (18 Nov 1997) |
| genetics, population | The study of the genetic composition of populations and of the effects of factors such as selection, population size, mutation, migration, and genetic drift on the frequencies of various genotypes and phenotypes. (12 Dec 1998) |
| growth rate of population | <epidemiology> A measure of population change in the absence of migration, comprising addition of newborns and subtraction of deaths; the result is known as the natural rate of increase of the population; it is the difference between the crude birth rate and the crude death rate. (05 Mar 2000) |
| rural population | The inhabitants of rural areas or of small towns classified as rural. (12 Dec 1998) |
| p in population genetics | The frequency of the more common of two different alternative (allelic) versions of a gene. (the frequency of less common allele is q). (12 Dec 1998) |
| population | 1. <genetics> A stable group of randomly interbreeding individuals. 2. <statistics> The set of objects or individuals from which a random sample is drawn. Origin: L. Populatio, from populus = people (18 Nov 1997) |
| population characteristics | <epidemiology> Qualities and characterization of various types of populations within a social or geographic group, with emphasis on demography, health status, and socioeconomic factors. (12 Dec 1998) |
| population control | Includes mechanisms or programs which control the numbers of individuals in a population of humans or animals. (12 Dec 1998) |
