| 설명 | 분석역학에서의 요인-대조연구의 한 기법이다. 사람의 집단에서 질병유행과 가설요인과의 연관성을 고찰하여 인과관계를 밝히는 것을 목적으로 한다. 가설요인을 갖는 집단과 갖지 않는 집단, 혹은 적은 집단과 많은 집단의 2군(코호트)으로 나누어 추적 조사하여 각 집단에서의 질병의 발생빈도를 비교하는 것이다. 일반적으로는 전향적인 연구로 행해지는 경우가 많으나 후향적인 연구로도 행하여진다. |

| amide linkage | <biochemistry> This is a carboxylic acid containing an amino group (-NH2). In an alpha amino acid, the amino group is attached to the carbon atom directly beside the carboxyl group. (09 Oct 1997) |

| map, linkage | A map of the genes on a chromosome based on linkage analysis. A linkage map does not show the physical distances between genes but rather their relative positions, as determined by how often two gene loci are inherited together. The closer two genes are (the more tightly they are linked), the more often they will be inherited together. Linkage distance is measured in centimorgans (cm). (12 Dec 1998) |
| genetic linkage | <genetics> The term refers to the fact that certain genes tend to be inherited together, because they are on the same chromosome. Thus parental combinations of characters are found more frequently in offspring than nonparental. Linkage is measured by the percentage recombination between loci, unlinked genes showing 50% recombination. See: linkage equilibrium, linkage disequilibrium. (18 Nov 1997) |
| glucosidic linkage | <biochemistry> The linkages between dextrose molecules in a glucoside compound which must be hydrolysed (broken apart) to produce the dextrose molecules. (09 Oct 1997) |
| medical record linkage | The creation and maintenance of medical and vital records in multiple institutions in a manner that will facilitate the combined use of the records of identified individuals. (12 Dec 1998) |
| phosphodiester linkage | <biochemistry> A chemical linkage in which two alcohols are esterically boundto a bridging molecule of phosphoric acid. (31 Dec 1997) |
| Y-linkage | The state of a genetic factor (gene) being borne on the Y chromosome. This idea is analogous with X-linkage but since the Y chromosome does not fully take part in chiasma formation and recombination, it not amenable to analysis by conventional linkage methods. Little is known about its content. There is a gene for the H-Y antigen, and indirect arguments suggest that there is a principle that determines the formation of the testis and masculinization of the foetus but its localization, though narrowing the limits, remains elusive. (05 Mar 2000) |
| linkage | <genetics> Tendency for two or more non-allelic genes to be inherited together, because they are located more or less closely on the same chromosome. Thus parental combinations of characters are found more frequently in offspring than nonparental. Linkage is measured by the percentage recombination between loci. (04 Jul 1999) |
| linkage analysis | <genetics> Study aimed at establishing linkage between genes. Today linkage analysis serves as a way of gene-hunting and genetic testing. (12 Dec 1998) |
| linkage disequilibrium | <genetics> The occurrence of some genes together, more often than would be expected. Thus, in the HLA system of histocompatibility antigens, HLA A1 is commonly associated with B8 and DR3 and A2 with B7 and DR2, presumably because the combination confers some selective advantage. (18 Nov 1997) |
| linkage equilibrium | <genetics> Situation that should exist in a population undisturbed by selection, migration, etc., in which all possible combinations of linked genes should be present at equal frequency. The situation is no more common than are such undisturbed populations. (18 Nov 1997) |
| linkage group | A set of two or more loci that have been shown by linkage analysis to be physically close in the genome but that have not yet been assigned to specific chromosomes. It is rapidly becoming an outmoded term. (05 Mar 2000) |
| linkage map | <genetics> A map of the relative positions of genetic loci on a chromosome, determined onthe basis of how often the loci are inherited together. Distance ismeasured in centimorgans (cM). (09 Oct 1997) |
| linkage marker | A locus at which there is a high probability of heterozygotes (indispensible state for linkage analysis), but in itself perhaps of no clinical interest. See: marker locus. (05 Mar 2000) |
| analytic study | In epidemiology, a study designed to examine associations, commonly putative or hypothesised causal relationships; usually concerned with identifying or measuring the effects of risk factors or with the health effects of specific exposures. (05 Mar 2000) |
