Abstract

Seasickness not only makes persons on board vessels to vomit but also causes vertigo, headache, sleepiness, fatigue, lethargy and other discomforts. This ailment leads to disturbance of biorhythm and decline of perception which would eventually cause reduction of situational awareness among ship's operators that leads to marine accident. This study is about the sensitivity of people onboard ships to seasickness and focused on deck or navigation officer cadets(apprentice officers) and engine officer cadets(apprentice engineers) who have no previous experiences on board. It is conducted by using motion sensor that can measure ship's X, Y, Z-axis motions and through the questionnaire survey, and evaluated each students' degree of seasickness symptoms. Through this study, in same circumstance, we have known that there are different degrees of motion sickness for wheel house worker and engine room worker, It also confirmed that seasickness have high relationship with degree of hull motion and also, with cycle of hull motion. In addition, we have confirmed that Z-axis hull movement has higher relationship with seasickness than X-axis and Y-axis hull movements. This study aims to initiate additional researches about X-axis and Y-axis of the ship's motion which it expects to greatly enhance safety of wheelhouse and engine room personnel, ship's livability and comfortable sailing.

멀미는 구토 증상뿐만 아니라 현기증, 두통, 졸음, 피로감, 무기력증 등을 동반하여 선박운항자의 신체리듬과 판단능력을 저하시켜 해양사고로 이어질 수 있다. 이 연구는 승선경험이 없는 조타실 근무자(실습항해사)와 기관실 근무자(실습기관사)를 대상으로 뱃멀미 민감성에 대하여 조사하였다. 선박의 X, Y, Z축 방향에 대한 선체운동을 측정할 수 있는 선체운동계측장비(motion sensor)를 이용하여 선체의 운동을 계측하였고, 설문을 통해 조타실과 기관실 근무자의 멀미에 대한 증상 정도(VIR, VSR)를 산출하였다. 이 연구를 통해 동일한 상황에서 조타실 근무자와 기관실 근무자간에 느끼는 멀미 정도에 차이가 있다는 것을 알 수 있었으며, 멀미는 선체 움직임의 크기뿐만 아니라 움직임의 주기와도 높은 연관성이 있다는 것을 확인할 수 있었다. 또한 X축과 Y축 방향 선체운동보다 Z축 방향의 선체운동이 멀미와 상관관계가 높았다. Z축 이외 X축과 Y축에 대한 연구가 진행된다면 조타실과 기관실 근무자의 안전과 선박의 거주성 및 승선감 향상에 크게 기여할 수 있을 것으로 기대된다.
