| 설명 | 협심증이 일어나기 쉬운 환자에게서 그 정도를 판단하기위해 시행한다. 방법은 같은 곳에서 환자를 달리도록 한 다음, 얼마의 속도에서 혈압이 떨어지고 협심증 증상이 나타나는가를 검사한다. 대개 심할수록 낮은 속도에서도 증상이 빨리 나타난다. |

| 설명 | 1. 적응하기 어려운 환경에 처할 때 느끼는 심리적-신체적 긴장상태. 장기적으로 지속되면 심장병, 위궤양, 고혈압 따위의 신체적 병을 일으키기도 하고 불면증, 노이로제, 우울증 따위의 심리적 부적응을 나타내기도 한다. ‘긴장’, ‘불안’, 짜증‘으로 순화. 2. 일반적으로 재료에 외력을 주면 그에 따라 변형되지만 탄성한계 안에서는 그 외력과 균형을 이루는 힘이 내부에 생긴다. 이를 응력이라 한다. 외력을 더욱 증가시키면 외력을 제거해도 원상으로 복구되지 않는다. 이를 금속의 가공에 응용한다. 응력은 이들 외력에 저항하는 물질내부의 원자력 사이의 힘을 말하지만 그것은 실용적인 것은 아니기 때문에 보다 마크로적으로 단위면적에 대한 하중에 저항하는 힘을 응력으로 하고, 방향과 크기가 있는 벡터량(kgf/ mm2)(kgf/cm2)(MPa)으로서 나타낸다. |

| shear | 1. To cut, clip, or sever anything from with shears or a like instrument; as, to shear sheep; to shear cloth. It is especially applied to the cutting of wool from sheep or their skins, and the nap from cloth. 2. To separate or sever with shears or a similar instrument; to cut off; to clip (something) from a surface; as, to shear a fleece. "Before the golden tresses . . . Were shorn away." (Shak) 3. To reap, as grain. 4. To deprive of property; to fleece. 5. <mechanics> To produce a change of shape in by a shear. See Shear. Origin: Sheared or Shore; Sheared or Shorn; Shearing] [OE. Sheren, scheren, to shear, cut, shave, AS. Sceran, scieran, scyran; akin to D. & G. Scheren, Icel. Skera, Dan. Skire, Gr. Cf. Jeer, Score, Shard, Share, Sheer to turn aside. 1. A pair of shears; now always used in the plural, but formerly also in the singular. See Shears. "On his head came razor none, nor shear." (Chaucer) "Short of the wool, and naked from the shear." (Dryden) 2. A shearing; used in designating the age of sheep. "After the second shearing, he is a two-sher ram; . . . at the expiration of another year, he is a three-shear ram; the name always taking its date from the time of shearing." (Youatt) 3. <engineering> An action, resulting from applied forces, which tends to cause two contiguous parts of a body to slide relatively to each other in a direction parallel to their plane of contact; also called shearing stress, and tangential stress. 4. <mechanics> A strain, or change of shape, of an elastic body, consisting of an extension in one direction, an equal compression in a perpendicular direction, with an unchanged magnitude in the third direction. Shear blade, one of the blades of shears or a shearing machine. Shear hulk. See Hulk. Shear steel, a steel suitable for shears, scythes, and other cutting instruments, prepared from fagots of blistered steel by repeated heating, rolling, and tilting, to increase its malleability and fineness of texture. Origin: AS. Sceara. See Shear. Source: Websters Dictionary (01 Mar 1998) |
| shear fields | <radiobiology> As used in plasma physics, this refers to magnetic fields having a rotational transform (or, alternatively, safety factor) that changes with radius (for example, in the stellarator concept, magnetic fields that increase in pitch with distance from the magnetic axis.) (09 Oct 1997) |
| shear flow | A flow of a material in which parallel planes in the material are displaced in a direction parallel to each other. (05 Mar 2000) |
| shear rate | The change in velocity of parallel planes in a flowing fluid separated by unit distance; its units expressed in seconds-1. (05 Mar 2000) |
| abiotic stress | <botany> Nonliving environmental factors (such as drought, extreme cold or heat, high winds) that can have harmful effects on plants. (06 May 1997) |
| acute stress reaction | A sudden bout of anxiety that is often accompanied by the features of hyperventilation (tingling around mouth and in fingertips, rapid breathing, faintness or fainting). (27 Sep 1997) |
| biotic stress | <biology> Living organisms which can harm plants, such as viruses, fungi, bacteria, and harmful insects. (19 Jan 1998) |
| magnetic stress tensor | <radiobiology> A second-rank tensor, proportional to the dyadic product of the magnetic field (B) with itself. The divergence of the magnetic stress tensor gives that part of the force which a magnetic field exerts on a unit volume of conducting fluid due to the curvature of the magnetic field lines. (09 Oct 1997) |
| contraction stress test | A test used to evaluate foetal well-being by inducing contractions and analyzing the foetal heart rate response. (05 Mar 2000) |
| porcine stress syndrome | A severe form of fever that occurs as a reaction to certain anaesthetic agents and muscle relaxants. Malignant hyperthermia is an inherited autosomal dominant condition. Inheritance: autosomal dominant. (27 Sep 1997) |
| posttraumatic stress | A psychological disorder that develops in some individuals who have had major traumatic experiences (and, for example, have been in a serious accident or through a war). The person is typically numb at first but later has symptoms including depression, excessive irritability, guilt (for having survived while others died), recurrent nightmares, flashbacks to the traumatic scene, and overreactions to sudden noises. Posttraumatic stress became known in the 70s due to the adjustment problems of some vietnam veterans. It was listed as a diagnostic category by the american psychiatric association in 1980. Although the name post-traumatic stress was new, the condition was not. It was known as shell shock in world war i and battle fatigue during world war II. (12 Dec 1998) |
| posttraumatic stress disorder | Development of characteristic symptoms following a psychologically traumatic event that is generally outside the range of usual human experience; symptoms include numbed responsiveness to environmental stimuli, a variety of autonomic and cognitive dysfunctions, and dysphoria. (05 Mar 2000) |
| posttraumatic stress syndrome | <syndrome> A disorder appearing after a physically or psychologically traumatic event outside the range of usual human experience, (e.g., a serious threat to one's life or seeing a loved one killed), characterised by symptoms of re-experiencing the event, numbing of responsiveness to the environment, exaggerated startle response, guilt feelings, impairment of memory, and difficulties in concentration and sleep. (05 Mar 2000) |
| heat stress disorder | A group of conditions due to overexposure to or overexertion in excess environmental temperature. It includes heat cramps, which are non-emergent and treated by salt replacement; heat exhaustion, which is more serious, treated with fluid and salt replacement; and heatstroke, a condition most commonly affecting extremes of age, especially the elderly, accompanied by convulsions, delusions, or coma and treated with cooling the body and replacement of fluids and salts. (12 Dec 1998) |
| shear stress |
Shear stress is the result of the force that is generated in a melt to overcome its resistance to a particular flow situation. Shear stress is the product of a material and shear rate.

| shear stress |
frictional force overcome in sliding one "layer" of fluid along another, as in any fluid flow. The shear stress of a petroleum oil or other Newtonian fluid at a given temperature varies directly with shear rate (velocity). The ratio between shear stress and shear rate is constant; this ratio is termed viscosity of a Newtonian fluid, the greater the shear stress as a function of rate of shear. In a non-Newtonian fluid
