Abstract

This study was limited to tying (connecting) knots using rescue ropes, and 5 subjects were selected for the experiment. After performing the correct knot, single-layer knot, figure-8 connecting knot, and fisherman's knot, the speed and convenience of each were analyzed. The results of analyzing the most convenient and fastest rope connecting method in rope tying are as follows. The correct knot and single-layer knot showed similar values of 11.80 seconds and 13.20 seconds, respectively. The figure-8 connecting knot showed significantly higher time of 19.00 seconds, which seems to be because the method of making a loop in the shape of a figure-8 and then inserting the rope along the figure-8 shape took some time to connect the rope. The fisherman's knot showed the lowest time of 9.80 seconds. This method overlaps the rope and forms a sling knot on the left and right, so it seems that the overall result is easy for the subjects to learn because it involves wrapping the rope once and pulling it out in the opposite direction. In an emergency rescue situation, the fisherman's knot is considered to be the most appropriate way to quickly and firmly connect ropes.

이 연구는 구조 로프를 활용한 매듭 중 이어 매기(연결)에 한정하고, 실험대상자 5명을 선발하여 실험하였다. 바른 매듭, 한겹매듭, 8자 연결 매듭, 피셔맨 매듭을 시행한 후, 각각의 신속성과 편리성을 분석하였다. 로프 이어 매기에서 가장 편리하고 신속한 로프 연결 방법을 분석한 결과는 다음과 같다. 바른 매듭과 한겹 매듭이 각각 11.80초, 13.20초로 비슷한 수치를 나타내었다. 8자 연결 매듭은 19.00초로 유의하게 높게 나타났는데, 이것은 로프를 8자 형태의 고리를 만든 후에 다시 8자 형태를 따라 로프를 삽입하는 방법이 로프 연결에 다소 시간이 소요된 것으로 보인다. 피셔맨 매듭은 9.80초가 소요되어 가장 낮은 수치로 나타났다. 이 방법은 로프를 겹친 후 좌우에 옭매듭을 형성하는 것으로 한번 로프를 감아서 반대로 빼주면 되므로 전체적으로 실험대상자가 숙지하기 쉬운 결과로 보인다. 긴급한 구조상황에서 로프를 신속하고 견고하게 로프를 연결하는 적정한 방법은 피셔맨 매듭으로 판단된다.
