| 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. |

| 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.

| 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 | The force acting in shear flow expressed per unit area; units in the CGS system: dynes/cm2. (05 Mar 2000) |
| stress | 1. Forcibly exerted influence, pressure. In dentistry, the pressure of the upper teeth against the lower in mastication. 2. The sum of the biological reactions to any adverse stimulus, physical, mental or emotional, internal or external, that tends to disturb the organisms homeostasis, should these compensating reactions be inadequate or inappropriate, they may lead to disorders. The term is also used to refer to the stimuli that elicit the reactions. (18 Nov 1997) |
| stress-bearing area | Surfaces of structures that resist forces, strains, or pressures brought upon them during function. (05 Mar 2000) |
| stress breaker | A device that relieves the abutment teeth, to which a fixed or removable partial denture is attached, of all or part of the forces generated by occlusal function. (05 Mar 2000) |
| stress disorders, posttraumatic | Anxiety disorders manifested by the development of characteristic symptoms following a psychologically traumatic event that is outside the normal range of usual human experience. Symptoms include re-experiencing the traumatic event and numbing of responsiveness to or reduced involvement with the external world. (12 Dec 1998) |
| stress echocardiogram | <investigation> An echocardiogram that is performed after a period of physical exertion. Chemical stimulation of the heart (to mimic exertion) is used in some cases where physical activity is not possible. In some cases, exertion may manifest a cardiac abnormality not obvious during echocardiography in the resting heart. (27 Sep 1997) |
| stress echocardiography | Echocardiographic monitoring of a circulatory challenge, usually exercise. Transesophageal echocardiography, recording of the echocardiogram from a transducer swallowed by the patient to predetermined distances in the oesophagus and stomach. Transthoracic echocardiography, the standard echocardiography recorded from echocardiographic "windows" on the precordium. Two-dimensional echocardiography, echocardiography in which an image is reconstructed from the echoes stimulated and detected by a linear array or moving transducers. Synonym: B-mode echocardiography, cross-sectional echocardiography. (05 Mar 2000) |
| stress fibre | <physiology> Long bundles of microfilaments made up of actin subunits. They are involved in the attachment of cultured cells to a substratum, the determination of cell shape and may be involved in cellular mobility. They are found in most cells and have been shown to be contractile, have a periodicity reminiscent of the sarcomere and are anchored at one end to a focal adhesion, although sometimes between two focal adhesions. (17 Jul 2002) |
| stress fracture | <orthopaedics, radiology> A hairline or microscopic break in the bone that is not demonstrable with conventional X-rays. Symptoms include a dull aching pain with tenderness at the site. Symptoms often increase with activity and diminish with rest. Nuclear bone scanning will reliably demonstrate stress fractures where conventional radiographs often fail. Although they may occur in most any location, they are most common in the tibia, fibula and metatarsal bones. (27 Sep 1997) |
| stress immunity | Insusceptibility or resistance to the effects of emotional strain. (05 Mar 2000) |
| stress induced protein | <molecular biology> Alternative and preferable name for heat-shock proteins of eukaryotic cells, which emphasises that the same small group of proteins is stimulated both by heat and various other stresses. (18 Nov 1997) |
| stress, mechanical | A purely physical condition which exists within any material because of strain or deformation by external forces or by non-uniform thermal expansion; expressed quantitatively in units of force per unit area. (12 Dec 1998) |
| stress, psychological | Stress wherein emotional factors predominate. (12 Dec 1998) |
