| 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. |

| radiofrequency | 1. Radiant energy of a certain frequency range; e.g., radio and television employ radiant energy having a frequency between 105-1011 Hz, while diagnostic X-rays have a frequency in the range of 3 × 1018 Hz. 2. In magnetic resonance imaging, the energy applied to switch or create a gradient in the magnetic field. (05 Mar 2000) |

| radio frequency or radiofrequency | <physics> Term used to describe electromagnetic radiation with frequencies less than infrared, but greater than audio frequencies, i.e., greater than about 15,000 Hz. Wavelengths are therefore less than about 20,000 km and greater than about 0.01 mm. (These numbers are not precise.) (09 Oct 1997) |
| radiofrequency plugging | <radiobiology> Use of axial ponderomotive force to plug an open-ended device. First demonstrated on RFC-XX, Institute of Plasma Physics, Nagoya University, Nagoya, Japan, and later demonstrated in the Phaedrus device at the University of Wisconsin. (09 Oct 1997) |
| radiofrequency pulse | In nuclear magnetic resonance, a short electromagnetic signal used to change the direction of the magnetic field. See: sequence pulse. (05 Mar 2000) |
| radiofrequency trapping | <radiobiology> Use of RF waves to pitch angle scatter particles flowing axially into a magnetic mirror cell. The particles are scattered out of the loss cone and are trapped. (See entries for pitch angle scattering, magnetic mirror, loss cone.) (09 Oct 1997) |
| British Thermal Unit | <unit> Unit of energy needed to raise one pound of water by one degree fahrenheit. It is equal to 252 calories or 1055 Joules. Acronym: BTU (13 Nov 1997) |
| differential thermal analysis | Technique by which phase transitions of chemical reactions can be followed by observation of the heat absorbed or liberated. (12 Dec 1998) |
| thermal | Pertaining to or characterised by heat. (18 Nov 1997) |
| thermal anaesthesia | Loss of temperature appreciation. (05 Mar 2000) |
| thermal barrier | <radiobiology> In magnetic mirror devices, this is a depression of electrostatic potential formed by enhancing ion loss in the region between the central cell and the positive potential plug. The thermal barrier significantly reduces the density requirements in the plug and lowers the overall power required to sustain the solenoidal plugging by thermally decoupling central cell electrons from the end plugs. (09 Oct 1997) |
| thermal burn | A burn caused by heat. (05 Mar 2000) |
| thermal capacity | <chemistry> The amount of energy required to raise the temperature of an object by one degree Celsius (or Kelvin), it is represented by the symbol C and is given in units of J/K. (09 Jan 1998) |
| thermal conductivity | <radiobiology> Degree to which a substance transmits heat. (basic definition, I believe, is: (heat flow) = (thermal conductivity) (temperature gradient)) (09 Oct 1997) |
| thermal conversion cycle | <radiobiology> Process of generating electrical power with a fusion reactor by means of a steam / other gas turbine. This is distinct from direct conversion cycles. (09 Oct 1997) |
| thermal cover | Vegetative condition, generally with greater than 70% canopy closure and 40 feet in height, that can significantly ameliorate weather effects such as wind, heat, cold, and snow. Used by wildlife in winter. (05 Dec 1998) |
