| 설명 | 나이 먹는다는 의미로 사용되기도 하지만 일반적으로는 성장이 완료, 정지되고 그 이후에 일어나는 모든 과정을 가리킨다. 나이를 먹어감에 따라 생체의 여러 가지 기능이 저하되는데, 일반적으로 세포에 색소가 축적되거나 세포자체나 핵이 작아지는 현상이다. 개개의 세포 기능도 저하되고, 세포 내에 색소가 침착되며, 기관은 암갈색을 띤다. 또한 피부는 얇아지고 털주머니도 위축되며, 모발은 색소를 잃고 탈모된다. 현재 많은 학자들은 세포내 DNA가 끊어지거나 끊어진 경우 수복력이 감소하거나, 면역력이 저하하기 때문으로 보고 있다. 노화가 일어나는 것은 세포의 종류에 따라서 크게 다른데 신경세포처럼 태어나서 죽을 때까지 세포분열하지 않는 세포는 노화가 두드러지고 고환이나 골수의 세포처럼 항상 분열하는 세포는 노화현상이 거의 일어나지 않는다. 발병과 죽음의 확률이 높아지지만, 노쇠성 변화와 병적 변화와의 경제는 명확하지 않다. 노쇠를 야기하는 노화의 본질적 원인에 대해서는 아직 정설이 없다. |

| knowledge | 1. The act or state of knowing; clear perception of fact, truth, or duty; certain apprehension; familiar cognizance; cognition. "Knowledge, which is the highest degree of the speculative faculties, consists in the perception of the truth of affirmative or negative propositions." (Locke) 2. That which is or may be known; the object of an act of knowing; a cognition; chiefly used in the plural. "There is a great difference in the delivery of the mathematics, which are the most abstracted of knowledges." (Bacon) "Knowledges is a term in frequent use by Bacon, and, though now obsolete, should be revived, as without it we are compelled to borrow "cognitions" to express its import." (Sir W. Hamilton) "To use a word of Bacon's, now unfortunately obsolete, we must determine the relative value of knowledges." (H. Spencer) 3. That which is gained and preserved by knowing; instruction; acquaintance; enlightenment; learning; scholarship; erudition. "Knowledge puffeth up, but charity edifieth." (1 Cor. Viii. 1) "Ignorance is the curse of God; - Knowledge, the wing wherewith we fly to heaven." (Shak) 4. That familiarity which is gained by actual experience; practical skill; as, a knowledge of life. "Shipmen that had knowledge of the sea." (1 Kings ix. 27) 5. Scope of information; cognizance; notice; as, it has not come to my knowledge. "Why have I found grace in thine eyes, that thou shouldst take knowledge of me?" (Ruth II. 10) 6. Sexual intercourse; usually preceded by carnal; as, carnal knowledge. Synonym: See Wisdom. Origin: OE. Knowlage, knowlege, knowleche, knawleche. The last part is the Icel. Suffix -leikr, forming abstract nouns, orig. The same as Icel. Leikr game, play, sport, akin to AS. Lac, Goth. Laiks dance. See Know, and cf. Lake, Lark a frolic. Source: Websters Dictionary (01 Mar 1998) |
| knowledge, attitudes, practice | Knowledge, attitudes, and associated behaviours which pertain to health-related events such as procedures, diseases, or family planning. (12 Dec 1998) |
| knowledge of results | <psychology> The hypothesis that learning is facilitated when the learner is informed at each step about the progress he is making in his learning. It hypothesises also that learning is facilitated when the learner is promptly informed whether a particular response is correct, and if incorrect, of the direction of error. The two usages refer to distinguishable situations and probably to different psychological processes. (04 Jul 1999) |
| aging | The gradual changes in the structure and function of humans and animals that occur with the passage of time, that do not result from disease or other gross accidents, and that eventually lead to the increased probability of death as the person or animal grows older. It does not apply to microorganisms. (12 Dec 1998) |
| aging, premature | Changes in the organism associated with senescence, occurring at an accelerated rate. (12 Dec 1998) |
| cell aging | The decrease in the cell's ability to proliferate with the passing of time. Each cell is programmed for a certain number of cell divisions and at the end of that time proliferation halts. The cell enters a quiescent state after which it experiences cell death via the process of apoptosis. (12 Dec 1998) |
| clonal aging | The deterioration in successive generations of a clone; thus paramecia and other simple forms, if allowed to reproduce asexually for a number of generations, invariably undergo deterioration, the characters of each group of descendants progressively departing from those of the original sexually produced ancestor. (05 Mar 2000) |
| skin aging | The process of aging due to changes in the structure and elasticity of the skin over time. It may be a part of physiological aging or it may be due to the effects of ultraviolet radiation, usually through exposure to sunlight. (12 Dec 1998) |
| erythrocyte aging | Senescence of the red blood cell. Lacking the organelles that make protein synthesis possible, the mature erythrocyte is incapable of self-repair, reproduction, and carrying out certain functions performed by other cells. This limits the average life span of an erythrocyte to 120 days. (12 Dec 1998) |
