| 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. |

| 설명 | 사람의 적혈구 표면에는 여러 가지 항원성을 가진 물질이 존재한다. 즉 면역학적 반응을 일으킬 수 있는 물질을 표면에 가지고 있다. 그리고 사람의 피속에는 이것과 반응할 수가 있는 항체도 존재한다. 사람의 혈액은 이것에 따라 몇가지 형으로 분류할 수가 있고, 이것을 혈액형이라고 한다. 혈액형은 적혈구 표면에 있는 어떤 물질을 기준으로 하느냐에 따라서 여러 가지로 분류될 수 있다. 대표적인 혈액형의 구분 방법에는 ABO혈액형과 Rh혈액형이 있다. 1. ABO 혈액형 가장 많이 사용되고 있는 혈액형 구분법. 적혈구 표면에는 A, B형의 두 가지 물질을 하나, 혹은 둘, 또는 하나도 가지지 않을 수가 있다. 그리고 피속에는 이것과 반응해서 적혈구를 파괴하거나 응집시킬 수 있는 물질(항체)이 존재한다. 물론 자신의 적혈구가 가지고 있는 물질에 대한 항체는 존재하지 않는다. -A형 혈액형－적혈구 표면에 A항원, 혈액속에 B에 대한 항체 -B형 혈액형－적혈구 표면에 B항원, 혈액속에 A에 대한 항체 -AB형 혈액형－적혈구 표면에 A, B항원, 혈액속에 A,B에 대한 항체를 가지지 않는다. -O형 혈액형－적혈구 표면에 A, B항원 모두를 가지지 않고, 혈액속에 A, B에 대한 항원을 모두 가진다. 대개 이것을 이용하여 수혈의 타당성 여부를 조사한다. 만약 A형 혈액형을 가진 사람의 피를 B형 혈액형의 사람에게 수혈하면 B형 혈액형을 가진 자의 피속에 있는 A에 대한 항체때문에 들어온 A형의 적혈구는 파괴되거나, 응집이 된다. O형의 혈액형을 가진 사람의 혈액의 적혈구는 표면에 A, B의 어떠한 물질도 가지고 있지 않아서 어떠한 혈액형을 가진 사람에게 수혈해도 반응을 일으키지 않는다. 이와 같은 원리로 AB형의 혈액형을 가진 사람은 혈액속에 A, B에 대한 항체를 모두 가지고 있지 않으므로 어떠한 혈액형이라도 받을 수가 있다. 2. Rh혈액형 적혈구표면에 있는 D라는 물질을 기준으로 하여 혈액형을 나누는 방법. 만약 D라는 물질이 적혈구의 표면에 존재하면 Rh(+), 존재하지 않으면 Rh(－)라고 한다. ABO혈액형에서와 같이 Rh(+)혈액형을 가지는 사람의 피속에는 D라는 물질에 대한 항체가 존재하지 않지만 Rh(－)혈액형을 가진 사람의 피속에는 D에 대한 항체가 존재한다. ABO혈액형과 마찬가지로 수혈의 타당성을 결정하는데 중요한 역할을 한다. |

| 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) |
|---|---|
| blinded study | Clinical trials of drugs are often done blinded so that the patient does not know (is blinded as to) whether they are receiving the product being tested or the control/placebo to ensure that the results of a study are not affected by a possible placebo effect (by the power of suggestion). (12 Dec 1998) |
| blind study | A study in which the experimenter is unaware of which group is subject to which procedure. (05 Mar 2000) |
| case-control study | <epidemiology> A study in which the risk factors of people with a disease are compared with those without a disease. It is an epidemiological method that begins by identifying persons with the disease or condition of interest (the cases) and compares their past history of exposure to identified or suspected risk factors with the past history of similar exposures among persons who resemble the cases but do not have the disease or condition of interest (the controls). The relationship of an attribute to the disease can therefore be examined by comparing affected and non-affected individuals with regard to the frequency or levels of the attribute in each group. (05 May 2002) |
| retrospective study | <epidemiology> A study in which people are enrolled and then have their history of risks, infections or disease measured. (05 Dec 1998) |
| rosenzweig picture-frustration study | A projective test depicting cartoon-like characters in frustrating situations. The scoring of the subject's responses indicates the direction of hostility or aggression, that is, whether he blames himself, the other person, or the set of circumstances. (12 Dec 1998) |
| cohort study | A study using epidemiological methods, such as a clinical trial, in which a cohort with a particular attribute (e.g., smokers, recipients of a drug) is followed prospectively and compared for some outcome (e.g., disease, cure) with another cohort not possessing the attribute. (05 Mar 2000) |
| pioped study | <radiology> 251 patients with documented PE on pulmonary angiograms were given V/Q scans: 102 high probability, 105 intermediate probability, 39 low probability, 5 normal or near-normal (12 Dec 1998) |
| multicenter study | A controlled study executed by several cooperating institutions. (12 Dec 1998) |
| multigeneration study | Toxicity test in which at least 3 generations of the test organisms are exposed to the substance being assessed. Exposure is usually continuous. Any medical study which follows a family of people through several generations. (09 Oct 1997) |
| crossover study | <statistics> A study that compares two or more treatments or interventions in which the subjects or patients, upon completion of the course of one treatment, are switched to another. Usually refers to a study in which the subject is switched from the experimental to the control procedure (or vice versa). In the case of two treatments, a and b, half the subjects are randomly allocated to receive these in the order a, b and half to receive them in the order b, a. A criticism of this design is that effects of the first treatment may carry over into the period when the second is given. With this type of study, every patient serves as his or her own control. (21 Jun 2000) |
| cross-sectional study | <epidemiology> A study in which the presence or absence of disease or other health-related variables are determined in each member of the study population or in a representative sample at one particular time. This contrasts with longitudinal studies which are followed over a period of time. Synonym: horizontal study. (18 Jul 2002) |
| preclinical study | A study to test a drug, procedure or other medical treatment in animals. The aim is to collect data in support of safety. Preclinical studies are required before clinical trials can be started. (12 Dec 1998) |
| prospective study | <epidemiology> A study in which people are initially enrolled and then followed up at subsequent times. (05 Dec 1998) |
