| 영문 | isotope | 한글 | 동위원소 |
|---|---|---|---|
| 설명 | 원자번호는 같지만 질량 수가 다른 원소. 동위체라고도 한다. Isotope라는 명칭은 F. 소디가 명명한 것이다. 동위원소는 보통원소기호의 왼쪽 어깨에 질량수를 붙여 표시한다. 일반적으로 동위원소는 성질이 비슷하지만 원자번호가 작은 원소, 예를 들어 수소의 동위원소(수소 1H, 중수소 2H, 3중수소 3H) 등에서는 화학적 성질까지도 약간 다른데가 있다. 동위원소에는 안정한 동위원소와 불안정한 방사성동위원소가 있다. |

| 설명 | 약물에 의한 치료를 할 때 나타나는 치료목적에 부합되지 않는 불쾌한 작용, 즉 부작용을 역효과로 표현하는 경우가 있다. 세계보건기구(WHO)에서는 역효과란 “예방, 진단, 치료의 목적으로 사람에게 상용량의 약을 사용하였을 때 발현하는 장애로, 의도하지 않은 작용”이라고 정의하고 있다. 약물에 의한 치료를 할 때, 특히 주목하여야 할 일반적인 역효과로서 약물알레르기, 조혈장기 장애, 간-콩팥의 장애, 물질 대사 장애 등이 있다. 이 외에 임산부에게 투여하여 발생한 기형발생, 마약, 각성제, 기타 향정신제에 의한 의존성 형성도 중요하다. |

| radioactive isotope | <physics, radiobiology> An isotope of an element that has an unstable nucleus, it tries to stabilise itself by giving off ionising radiation. (09 Oct 1997) |
|---|---|
| stable isotope | A nonradioactive nuclide; an isotope that shows no tendency to undergo radioactive decomposition. (05 Mar 2000) |
| daughter isotope | An element produced by radioactive decay of another. See: radionuclide generator, cow. (05 Mar 2000) |
| isotope | <radiobiology> One of several nuclides having the same number of protons in their nuclei and hence having the same atomic number, but differing in the number of neutrons and therefore, in the mass number. Almost identical chemical properties exist between isotopes of a particular element. The use of this term as a synonym for nuclide is to be discouraged. (16 Dec 1997) |
| isotope clearance | The rate at which an isotope is removed (usually by blood flow) from a tissue or organ such as the brain. (05 Mar 2000) |
| isotope labeling | Techniques for labeling a substance with a stable or radioactive isotope. It is not used for articles involving labelled substances unless the methods of labeling are substantively discussed. Tracers that may be labelled include chemical substances, cells, or microorganisms. (12 Dec 1998) |
| kinetic | Pertaining to or producing motion. <study> Kinetics: The study of reaction rates and the study of the relationship between force and mass. (14 Oct 1997) |
| kinetic analyzer | An instrument that measures the rate of change in a chemical substance; used mainly for enzyme measurement. (05 Mar 2000) |
| kinetic ataxia | Ataxia developing upon attempting to perform coordinated muscular movements. Synonym: kinetic ataxia. (05 Mar 2000) |
| kinetic energy | <chemistry> Energy due to the motion of an object (09 Jan 1998) |
| kinetic measurement | Continuous or frequent monitoring of the readings in a chemical reaction to determine its rate. (05 Mar 2000) |
| kinetic molecular theory | <chemistry> This theory assumes that molecules must collide in order to react. The more collisions the more likely it is for a reaction to occur. However, depending on the conditions, only a small fraction of the collisions are effective in producing a reaction. There are several constraints. In order for a reaction to occur, bonds initially are broken, which requires energy. This energy depends on the type of the reaction and comes from the kinetic energies that the molecules possess before the collision. It is called the activation energy. Increasing the temperature increases the kinetic energies and more collisions will occur. In adition, at a higher temperature a greater number of the reacting molecules might possess an energy equal to or greater than the activation energy. However the molecules must also collide in a specific orientation, called the steric factor in order for a reaction to occur. A reaction will only be successful, if the collision has enough energy to be either equal to or greater than the activation energy and if the orientation of the collision allows for correct bond formation. These factors are in the Arrhenius equation: k = zp The rate constant k is proportional to the Arrhenius factor A. A is the product of the collision frequency z, and the steric factor p. The fraction of collisions with sufficient energy to produce a reaction are in the term of the equation. (09 Jan 1998) |
| kinetic perimetry | Mapping of the visual field by using a moving rather than a static test object. (05 Mar 2000) |
| kinetic strabismus | Strabismus due to spasm of an extraocular muscle. (05 Mar 2000) |
| kinetic system | A term proposed by G.W. Crile to denote the chain of organs through which latent energy is transformed into motion and heat: it includes the brain, the thyroid, the adrenals, the liver, the pancreas, and the muscles, that part of the neuromuscular system whereby active movements are effected; distinguished from the static system.
