| 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. |

| 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) |

| international | 1. Between or among nations; pertaining to the intercourse of nations; participated in by two or more nations; common to, or affecting, two or more nations. 2. Of or concerning the association called the International. International code, a common system of signaling adopted by nearly all maritime nations, whereby communication may be had between vessels at sea. International copyright. See Copyright. International law, the rules regulating the mutual intercourse of nations. International law is mainly the product of the conditions from time to time of international intercourse, being drawn from diplomatic discussion, textbooks, proof of usage, and from recitals in treaties. It is called public when treating of the relations of sovereign powers, and private when of the relations of persons of different nationalities. International law is now, by the better opinion, part of the common law of the land. Cf. Conflict of laws, under Conflict. Origin: Pref. Inter- + national: cf. F. International.

| International Classification of Disease | The classification of specific conditions and groups of conditions determined by an internationally representative expert committee that advises the World Health Organization, which publishes the complete list in a periodically revised book, the Manual of the International Statistical Classification of Diseases, Injuries and Causes of Death. The Tenth Revision (ICD) came into use in 1992; it has 20 chapters, each with a hierarchical arrangement of subdivisions (rubrics); some chapters are aetiological, more relate to body systems, some to classes of conditions, some to procedures. Acronym: ICD (05 Mar 2000) |
| International Classification of Health Problems in Primary Care | A classification of diseases, conditions and problems arranged for use in primary care where diagnostic precision is seldom possible. (05 Mar 2000) |
| International Classification of Impairments Disabilities and Handicaps | A WHO-sponsored numerical taxonomy of the impairments, disabilities and handicaps consequent upon injury and disease. (05 Mar 2000) |
| International Code of Zoological Nomenclature | <zoology> An Authoritative document containing a system of rules and recommendations to be followed in giving a scientific name to an animal or animal group. Adopted by the International Congresses of Zoology and Administered by the International Commission on Zoological Nomenclature. The most recent version of the Code, adopted in principle by the 20th General Assembly of the International Union of Biological Sciences at Helsinki in 1979, was approved by the ICZN late in 1983. With minor exceptions it retains the same format as the first two editions. Minor amendments for immediate incorporation are published in Bulletin Zoological Nomenclature as Declarations to remain in force until ratified or rejected by future congresses. (09 Jan 1998) |
| International Committee of the Red Cross | A neutral Swiss organization serving as an intermediary between contending forces in armed conflict, in civil war, or internal strife, to help victims receive protection and other humanitarian assistance under the Geneva Conventions in accordance with the fundamental principles of the Red Cross.
