Abstract

This study was limited to the underwater search part among water accidents on the inland water surface, and analyzed five underwater search methods and lifesaving time at 5m underwater. The subjects of the experiment were 10 people. The semi-circle search took the longest with 259 seconds, and the modified round-trip search took 78.60 seconds, showing a significant difference with an average of 180.04 seconds. Subjects B and D showed similar values, with average underwater search times of 199 seconds and 202 seconds, respectively. Subject C showed a significantly higher average underwater search time of 209 seconds. The reason seems to be from increased anxiety and excessive tension due to poor underwater watch. Subject A showed a significantly lower underwater search time of 187 seconds. The reason seems to be the result of E's experience being the most among the test subjects and his rich diving experience in the Han River with poor visibility. As for convenience, semicircle search showed a low score of 6~7, and modified reciprocal search showed a high score of 8~9. The most suitable rescue method as an underwater search method in the Han River where visibility is poor is determined to be a modified round-trip search method.

이 연구는 내수면의 수난사고 중에서도 수중수색 부분에 한정하고, 수중 5m에서 5가지 수중탐색 방법과 인명구조 시간을 분석하였다. 실험대상자는 10명으로. 반원 탐색은 259초로 가장 길었고, 변형된 왕복 탐색 방법은 78.60초로, 평균 180.04초의 유의미한 차이를 보였다. 실험대상자 B, D는 수중탐색 평균 시간이 각각, 199초, 202초로 비슷한 수치를 나타내었다. 실험대상자 C는 수중탐색 평균 시간이 209초로 유의하게 높게 나타났다. 그 이유는 수중 시계의 불량으로 인한 불안감 가중 및 과도한 긴장에서 기인한 것으로 보인다. 실험대상자 A는 수중수색 시간이 187초로 유의하게 낮게 나타났다. 그 이유는 E의 경력이 실험대상자 중 가장 많고, 시계가 불량한 한강에서의 잠수 경험이 풍부하여 나타난 결과로 보인다. 편리성은 반원 탐색은 6~7로 낮게, 변형된 왕복 탐색이 8~9로 높은 수치를 나타내었다. 시계가 불량한 한강에서의 수중탐색 방법으로 가장 적합한 구조 방법은 변형된 왕복 탐색 방법으로 판단된다.
