| 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) |
| american speech-language-hearing association | A professional society concerned with the diagnosis, prevention, treatment, and remediation of speech, language, and hearing disorders. (12 Dec 1998) |
| rehabilitation of hearing impaired | Procedures for assisting a person with a hearing disorder to maximum comprehension in communication. (12 Dec 1998) |
| resonance theory of hearing | That the basilar membrane of the cochlea acts as a resonating structure, recording low tones from its apical turns and high tones from its basal turns. Synonym: Helmholtz theory of hearing. (05 Mar 2000) |
| Weber's test for hearing | The application of a vibrating tuning fork to one of several points in the midline of the head or face, to ascertain in which ear the sound is heard best by bone conduction, that ear being the affected one if the sound-conducting apparatus (middle ear) is at fault (positive test), but probably the normal one if the neurosensory apparatus is diseased (negative test). (05 Mar 2000) |
| conductive hearing loss | <otolaryngology> A form of deafness that results from a blockage of the ear canal or dysfunction of the ossicles or eardrum (sound collecting apparatus). In conductive hearing loss the auditory nerve is normal, but there exists a physical problem with the sound collecting apparatus. (05 Jan 1998) |
| hearing | The sensation of sound. (12 Dec 1998) |
| hearing aid | An electronic amplifying device designed to bring sound more effectively into the ear; it consists of a microphone, amplifier, and receiver. (05 Mar 2000) |
