3) 콜레스테롤은 근무전 평균은 178.7㎎/㎗에서 근무후 평균은 186.7㎎/㎗로 증가하였다.
4) 전해질 검사값 중 칼슘은 근무전 평균은 9.6㎎/㎗에서 근무후 평균은 10.0㎎/㎗로,인의 근무전 평균은 3.5㎎/㎗에서 근무후 평균 3.7㎎/㎗로 증가하였다.
3. 임상적으로는 1건의 결핵발생이 있었으며, 정형외과적 질환을 중심으로 하는 다양한사고가 있었다. 정상군에서의 검사값의 변화는 임상적 의미가 적었으나, 위험군은 근무후에 건강상태가 많이 악화되었다. 당뇨와 고혈압이 있었던 종사자는 근무후 고혈압이 악화
되었으며, 허혈성심증 소견을 보였다. B형 간염 양성자 세명 중 두명이 1년간의 근무후복부초음파 검사에서 만성간염 소견을 보였다.
그럼에도 불구하고 대다수의 세종기지 종사자 대부분은 근무후에 건강했다. 그러나, 근무전 건강검진에서 이상 소견을 보인 고위험군은 남극이 가지는 지역적 특성에 따라 필요시에 적정한 의료를 즉각적으로 받을 수 없다는 위험성이 있으므로, 근무를 제한할 필요가 있다. 그러므로 대원선발을 위한 적정한 신체적 기준이 마련되어야 한다. 또한 세종기지 근무가 장기적으로 신체적 측면, 사회적 측면, 정신적 측면에서 어떠한 영향을 미치는 가에 대한 앞으로의 추적연구가 필요하다. 이를 위해 우리 나라도 극지연구에 의료분과를 포함시켜야 하며, 의학적 자료를 체계적으로 수집해야 한다.

The main purpose of this study is to evaluate the influence of the 1 year stay at King Sejong Station on the health status of the members of the expedition team. From 1987 to 1997, the total number of persons who have participated in the Korea Antarctic Research Expedition program was 144. The size of the analytical sample was 90 persons, with both the pre-and post-winter-over health exam records available.
The results were as follows:
1. The mean age of the subject was 33.9 years old and 73.6% of the subjects were married.
2. Significant changes were observed in liver function test, hematologic exam, cholesterol level and electrolyte level after winter-over.
1) The mean AST level increased from 21.1IU to 25.4IU after winter-over. The mean ALT level and ALP level increased from 22.6IU to 29.4IU, from 146.9IU to 166.01IU, respectively.
2) The mean hematocrit level increased from 45.1% to 47.4% after winter-over. The mean hemoglobin level increased from 15.5g/㎗ to 15.9g/㎗, and WBC count, from 6.9(10³/m³) to 7.7(10³/m³).
3) The mean cholesterol level increased from 178.7㎎/㎗ to 186.7㎎/㎗.
4) The mean calcium level increased from 9.6㎎/㎗ to 10.0㎎/㎗, and the phosphorus level, from 3.5㎎/㎗ to 3.7㎎/㎗.
3. One case of tuberculosis was reported and many accidents, mainly related to orthopedic injury, occurred. Changes in the value among normal individuals did not show significant clinical meaning, but the health status of the high risk person aggravated after winter-over. For example, a researcher with diabetis
mellitus and hypertension had an aggravated hypertension after winter-over and developed ischemic heart disease. Two-thirds of the person with hepatitis B antigen developed chronic hepatitis in the abdominal sonogram taken after winter-over.
Overall, most of the people were healthy following winter-over. But high risk persons with abnormal pre-winter-over health status may need to be cautioned because of their high risk of aggravation of conditions and insufficient medical supply in antarctica. It may be necessary to consider selection criteria for winter-over personnel.
Further research on the long- term health effects of the antarctic experience through continuous follow-up of expedition members is necessary. A human biology and medicine part need to be established in the Korea Antarctic Research Program to facilitate this study.
