| 영문 | radiation dose | 한글 | 방사선량 |
|---|---|---|---|
| 설명 | 방사선조사의 정도. 방사선생물학이나 인체의 방사선방호에서는 전리방사선의 양, 즉 선량이 문제가 된다. 방사선량에서도 국제단위계(SI)가 채용되어 국제방사선방호위원회(ICRP)의 권고에 따라서 다음의 여러 단위가 널리 사용된다. ① 흡수선량(absorbed dose). 물질의 단위질량이 방사선에 의해 받아들이는 에너지. 이 단위는 방사선 및 물질의 종류가 어떠한 것이더라도 사용할 수 있다. 국제단위는 J/kg이며 이것에 고유한 명칭으로 그레이(gray, 기호 Gy)가 부여된다. 1Gy=100라드(rad). ② 조사선량(exposure) 또는 공중선량. X선 또는 γ선에 한해서 사용된다. 국제단위는 C/kg. ③ 선량당량(dose equivalent). 방사선방호를 위해 사용되는 양. 기호는 H. H는 방사선의 종류와 에너지에 의해 생체에 주는 효과를 보정하는 선질계수(Q)와 그 밖의 인자(예를 들면 선량률, 방사성동위원소에 의한 내부피폭시에는 그 핵종의 체내분포 등)에 근거한 보정계수(N)를 흡수선량(D)에 곱한 것, 즉 H=D-Q-N. 또한 D의 단위를 Gy 또는 rad로 표시하였을 때 H의 단위를 각각 시베르트(sievert, 기호 Sv) 및 렘(rem)이라고 한다. 따라서 1 Sv=102rem. 일반적으로 단위시간당의 선량을 선량률(dose rate)이라고 한다. |

| 영문 | dose | 한글 | 용량, 투여량, 방사선량 |
|---|---|---|---|
| 설명 | 1. 약제를 한 번 또는 하루에 사용하거나 복용하는 분량. 2. 물질이나 조직에 대한 방사선의 작용 정도를 나타내는 양. 즉, 방사선량이라는 개념은 어떤 한 점에 입사하는 방사선과 그 점 근처에 있는 물질에 대한 방사선의 물리적-화학적-생물학적 효과와의 관게를 정량적으로 나타내는 공통인 척도로서 생각된 것이다. 라드(rad)로 나타내는 흡수량, 렌트겐(R)으로 나타내는 조사 선량, 렘(rem)으로 나타내는 선량 당량으로 구분하여 쓴다. |

| 영문 | skin dose | 한글 | 피부선량 |
|---|---|---|---|
| 설명 | 1. 피부표면에서의 방사선의 공중선량으로 여기에는 1차방사선과 후방산란이 포함된다. 2. 피부에 흡수되는 선량. |

| infinitesimal | <mathematics> An infinitely small quantity; that which is less than any assignable quantity. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| active principle | A constituent of a drug, usually an alkaloid or glycoside, upon the presence of which the characteristic therapeutic action of the substance largely depends. (05 Mar 2000) |
| antianaemic principle | The material in liver (and certain other tissues) that stimulates haemopoiesis in pernicious anaemia; for practical purposes, the antianaemic effect of extracts from such tissues is approximately equivalent to the content of vitamin B12. (05 Mar 2000) |
| azygos vein principle | A principle based on the observation that animals can survive prolonged vena caval occlusion without sequelae: if blood from the azygos vein alone is permitted to enter the heart, patients are perfused during cardiac and pulmonary bypass at flows much less than the normal resting cardiac output. Synonym: low flow principle. (05 Mar 2000) |
| Bernoulli's principle | <physics> When friction is negligible, the velocity of flow of a gas or fluid through a tube is inversely related to its pressure against the side of the tube; i.e., velocity is greatest and pressure lowest at a point of constriction. Synonym: Bernoulli's principle, Bernoulli's theorem. (05 Mar 2000) |
| pain-pleasure principle | A psychoanalytic concept that, in a human's psychic functioning, he/she tends to seek pleasure and avoid pain; a term borrowed by experimental psychology to denote the same tendency of an animal in a learning situation. Synonym: pleasure principle. (05 Mar 2000) |
| reality principle | The concept that the pleasure principle in personality development is modified by the demands of external reality; the principle or force that compels the growing child to adapt to the demands of external reality. (05 Mar 2000) |
| Pauli's exclusion principle | The theory limiting the number of electrons in the orbit or shell of an atom; that it is not possible for any two electrons to have all four quantum numbers identical. (05 Mar 2000) |
| repetition-compulsion principle | In psychoanalysis, the impulse to redramatise or reenact earlier emotional experiences or situations. Synonym: principle of inertia. (05 Mar 2000) |
| melanophore-expanding principle | A polypeptide hormone secreted by the intermediate lobe of the hypophysis in humans (in neurohypophysis in certain other species) which causes dispersion of melanin by melanophores, resulting in darkening of the skin, presumably by promoting melanin synthesis; this effect is readily demonstated in some lower vertebrates, such as frogs and fish; alpha-melanotropin is an N-acetylated peptide with 13 amino acids; beta-melanotropin has 22 amino acids. Synonym: intermedin, melanocyte-stimulating hormone, melanophore-expanding principle. (05 Mar 2000) |
| Mitrofanoff principle | Use of an isolated appendix on a vascularised pedicle as a catheterizable route of access to the bladder from the skin. Synonym: Mitrofanoff principle. Origin: eppendico-+ L. Vesica, bladder, + G. Stoma, mouth (05 Mar 2000) |
| closure principle | In psychology, the principle that when one views fragmentary stimuli forming a nearly complete figure (e.g., an incomplete rectangle) one tends to ignore the missing parts and perceive the figure as whole. See: gestalt. (05 Mar 2000) |
| pleasure-pain principle | The psychoanalytic concept that man instinctively seeks to avoid pain and discomfort and strives for gratification and pleasure. (12 Dec 1998) |
| pleasure principle | A psychoanalytic concept that, in a human's psychic functioning, he/she tends to seek pleasure and avoid pain; a term borrowed by experimental psychology to denote the same tendency of an animal in a learning situation. Synonym: pleasure principle. (05 Mar 2000) |
| consistency principle | In psychology, the desire of the human being to be consistent, especially in his attitudes and beliefs; theories of attitude formation and change based on the consistency principle include balance theory, which suggests that the individual seeks to avoid incongruity in his various attitudes. See: cognitive dissonance theory. (05 Mar 2000) |
