| 영문 | cohort study | 한글 | 계획연구, 전향연구, 앞방향연구 |
|---|---|---|---|
| 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. |

| 영문 | flow | 한글 | 흐름, 유량 |
|---|---|---|---|
| 설명 | 액체 또는 기체의 각 부분이 시간과 함께 연속적으로 그 위치를 이동하는 현상. 그 양상은 복잡하지만 각 점에서의 흐름의 방향이 그 점에서의 접선 방향과 일치하도록 선을 그으면 흐름의 모양을 파악할 수 있게 된다. |

| 영문 | intermittent positive pressure breathing(IPPB) | 한글 | 간헐적양압호흡 |
|---|---|---|---|
| 설명 | 폐를 팽창시키기 위하여 대기압보다 높은 압력을 이용하는 인공호흡법이다. 신생아 무기폐의 치료나 만성 폐쇄성 호흡기 질환의 급성 악화시, 진단을 위한 가래의 배출을 위하여, 또는 약제의 흡입에 사용하고 있다. 합병증으로 공기가슴증이나 심박출량의 감소가 올 수 있다. |

| 영문 | pulse pressure | 한글 | 맥박압 |
|---|---|---|---|
| 설명 | 수축기 혈압과 확장기 혈압의 차이. mmHg로 표시한다. 심장의 수축력, 동맥 내 혈류량, 동맥벽의 긴장도에 영향을 받는다. 정상치는 수축기 혈압의 1/3, 또는 확장기 혈압의 1/2이다. 60mmHg이상을 대맥이라고 하며, 대동맥판막 폐쇄부족증, 갑상샘항진증, 동맥경화증, 혈압이 상승할 때 심장비대, 고열 등에서 볼 수 있다. 20mmHg 이하를 소맥이라고 하며, 급성 심근경색에 의한 좌심실 수축력 저하, 대동맥판막 협착등에서 볼 수 있다. 한편 맥압의 1/3에 확장기 혈압을 더한 것을 평균혈압이라고 한다. |

| 영문 | osmotic pressure | 한글 | 삼투압 |
|---|---|---|---|
| 설명 | 삼투라는 현상은 일정 크기 이하의 물질은 통과시키고 그 이상의 크기를 가진 물질은 통과 시키지 못하게 하는 막(반투막)을 사이에 두고 양쪽에 그 막을 투과하지 못하는 물질의 농도가 차이가 날 때 발생하는 것으로 막을 통과할 수 있는 물질이 막 양쪽의 통과 할 수 없는 물질의 농도를 같게 하는 방향으로 움직이는 것을 말한다. |

| isovolume pressure-flow curve | The relationship between transpulmonary pressure and respiratory air flow, expressed as a function of lung volume. (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) |
| 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) |
