| 설명 | 보라색보다 더욱 파장이 짧은 400nm 이하의 볼 수 없는 광선이며 다음의 3종으로 나눈다. ① 200~290nm(UVC): 저압램프에서 조사되는 것으로 DNA를 저해하며 피부에 조사되면 홍반이 생긴다. 대기중의 O3나 H2O에서 흡수된다. ② 290~320nm(UVB): 피부가 햇볕에 타서 검게 되며 지나치면 수포나 피부암을 일으킬 위험이 있다. ③ 320~400nm(UVA): 지표면에 많으며 무해하다. 다량이 폭로되면 피부에 색소침착을 일으킨다. |

| 설명 | 290~320nm의 자외선. 일광화상과 그을림을 가장 효과적으로 유발한다. 백인에서 자외선 과다는 피부암을 유발할 수 있다. |

| 설명 | 200~290nm의 자외선 방사. UVC라고도 한다. 일광의 UVC는 지구 표면에 도달하지 않는다. 멸균/수은아크등은 일광화상과 각막염을 유발할 수 있다. |

| spectroscopy, near-infrared | A noninvasive technique that uses the differential absorption properties of haemoglobin and myoglobin to evaluate tissue oxygenation and indirectly can measure regional haemodynamics and blood flow. Near-infrared light (nir) can propagate through tissues and at particular wavelengths is differentially absorbed by oxgenated vs. Deoxygenated forms of haemoglobin and myoglobin. Illumination of intact tissue with nir allows qualitative assessment of changes in the tissue concentration of these molecules. The analysis is also used to determine body composition.

| near | 1. Not far distant in time, place, or degree; not remote; close at hand; adjacent; neighboring; nigh. "As one near death." "He served great Hector, and was ever near, Not with his trumpet only, but his spear." (Dryden) 2. Closely connected or related. "She is thy father's near kinswoman." (Lev. Xviii. 12) 3. Close to one's interests, affection, etc.; touching, or affecting intimately; intimate; dear; as, a near friend. 4. Close to anything followed or imitated; not free, loose, or rambling; as, a version near to the original. 5. So as barely to avoid or pass injury or loss; close; narrow; as, a near escape. 6. Next to the driver, when he is on foot; in the Unted States, on the left of an animal or a team; as, the near ox; the near leg. See Off side, under Off, . 7. Immediate; direct; close; short. "The nearest way." 8. Close-fisted; parsimonious. Near may properly be followed by to before the thing approached'; but more frequently to is omitted, and the adjective or the adverb is regarded as a preposition. The same is also true of the word nigh. Synonym: Nigh, close, adjacent, proximate, contiguous, present, ready, intimate, dear. Origin: See Near. Source: Websters Dictionary (01 Mar 1998) |
| near drowning | Any almost drowning. All cases should be evaluated by a physician. Complications include aspiration pneumonia and adult respiratory distress syndrome. (27 Sep 1997) |
| near point | That point in conjugate focus with the retina when the eye exerts maximal accommodation. Synonym: punctum proximum. (05 Mar 2000) |
| near point of convergence | The point to which the visual lines are directed when convergence is at its maximum. (05 Mar 2000) |
| near point of the eye | <ophthalmology> The nearest point to the entrance of the pupil of the normal eye at which focus is attained without strain, 10 inches (250 mm) is the generally accepted distance. In very young people and in those with myopia, this distance is less. The near point recedes with age, possibly even causing farsighted condition,. (05 Aug 1998) |
| near reaction | The pupillary constriction associated with a near vision effort, i.e., with accommodation and convergence. (05 Mar 2000) |
| near reflex | Pupillary constriction with a near vision effort, with ocular convergence, or with accommodation; an associated reaction, not a true reflex. (05 Mar 2000) |
| near sight | <ophthalmology> That error of refraction in which rays of light entering the eye parallel to the optic axis are brought to a focus in front of the retina, as a result of the eyeball being too long from front to back (axial myopia) or of an increased strength in refractive power of the media of the eye (index myopia). Also called nearsightedness, because the near point is less distant than it is in emmetropia with an equal amplitude of accommodation. Origin: Gr. Myein = to shut (18 Nov 1997) |
| near-total thyroidectomy | Removal of nearly all of each thyroid lobe leaving unresected only a small portion of gland adjacent to the entrance of the recurrent laryngeal nerve into the larynx. (05 Mar 2000) |
| far-and-near suture | A suture utilizing alternate near and far stitches, used to approximate fascial edges. (05 Mar 2000) |
| light-near dissociation | A stronger near pupil response than light response; due to weak pupillomotor input, Argyll Robertson pupil, dorsal midbrain syndrome, or to misdirection of ciliary muscle fibres into the iris sphincter. Synonym: light-near dissociation. (05 Mar 2000) |
| vital ultraviolet | Rays necessary or helpful to normal growth; they promote calcium metabolism, are antirachitic in action, and have wavelengths between 3200 and 2900 A |
| microscopy, ultraviolet | Microscopy in which the image is formed by ultraviolet radiation and is displayed and recorded by means of photographic film. (12 Dec 1998) |
| near ultraviolet |
----Ultraviolet (UV) radiation is electromagnetic radiation of a wavelength shorter than that of the visible region, but longer than that of soft X-rays. It can be subdivided into near UV (380–200 nm wavelength) and extreme or vacuum UV (200–10 nm). ...
