IMO에서는 피로(Fatigue)를 정신력, 체력, 신속성, 반응시간, 기능의 조화, 의사결정, 마음의 안정 등을 포함한 모든 육체적, 정신적 또는 감정적인 소모의 결과로 인하여 인간의 육체적 또는 정신적 능력이 저하되는 것 즉, 인간의 효율성의 감소라고 정의하고 있다. 선박승무원의 피로는 선박안전운항과 해양환경보호를 위한 업무수행능력(Performance)에 영향을 미칠 뿐만 아니라 승선중인 선박승무원의 건강(Health)과도 밀접한 관계가 있으며 또한 많은 영향을 미치게 된다. 본 연구에서는 선박승무원의 피로에 영향을 미치는 다양한 요인과 그로 인한 효과들을 살펴보고 피로와 선박승무원의 건강과의 관련성 및 그 영향 등에 대하여 고찰을 하고자 한다.

This paper presents the crew members fatigue survey in order to understand the current state of various fatigue causal factors and personnel fatigue subjective symptoms, and then analyzes the survey items. The results of this survey are as follows. Firstly, many crew members were struggling with the lack of sleep and rest hour. Secondly, environmental factors such as weather, ship motion and vibration, noise, accommodation condition etc. disturbed the sleep of crew members. In third, their duty hours were more than 10 hours per day in certain types of ship. In fourth, they felt fatigue a lot when they were on board because of the workload and stress. Lastly, in some measurement items of fatigue symptoms(physical, mental, emotional), many crew members were experiencing more than moderate fatigue symptoms.

For many years, fatigue was discounted as a potential cause of or contributor to human error. However, resent accident data and research point to fatigue as a cause of and/or contributor to human error precisely because of its impact on performance. The goal of this study is to analyze and examine of the fatigue factors related to human error. In this study, we carried out the questionnaire sw-vey which concerned with the fatigue factors.

고품질 선박 평가의 중요한 척도인 진동허용 기준에 대한 관심이 점차 높아지고 있다. 진동 허 용기준은 선박 계약시 건조사양에 포함될 뿐 아니라 건조후 시운전 결과 평가시나 인도후 아프터 서비스 과정에서도 선주와 건조자간에 자주 거론되는 항목이다. 평가 관점으로서는 .승무원의 거주성 및 작업성 .구조 부재의 피로파괴 발생 가능성 .기계기기 기구들의 성능 보존성 등이 있으며 IOS(국제표준화기구)나 여러 선급 기준들이 사용되고 있다. 그러나 보다 쾌적한 거주구나 작업 구역을 원하는 탑승자들의 욕구가 커짐에 따라 최근 저 진동선을 요구하는 선주 들의 허용기준에 대한 관심 또한 늘어나고 있다. 이에 따라 IOS는 선박진동의 종합평가 기준인 IOS 6954 개정 작업을 진행중에 있으며 일부 선급에서도 자체적으로 보완한 기준들을 제시하고 있다. 반면에 조선소들의 입장에서 보면 그간 진동 예측 방법과 방진설계 기술이 발전된 덕분에 심각한 진동문제는 많이 줄어들었다 하겠으나 90년대 아후 선박의 고속화에 따른 기진력 증가로 인하여 저 진동 선박 건조가 쉽지만은 않은 것이 최근의 상황이다. 따라서 본 고에서는 현재 사용되는 각종 선박진동 허용 기준들을 다시 정리하고 그중 강화될 전망이 있는 거주구 진동 허용기준에 대한 변화 추세를 살펴보고자 한다.

Decrease in crew performance is frequently cited as a major causal factor in maritime accidents. Although considerable researches on working hours undertaken by seafarers have been conducted through interviews and record analyses, experimental studies on the effects of factors, such as high workload, shift patterns, stress, sleep deprivation, and disturbance on the cognitive performance of mariners have been limited. Other safety-critical transport industries, such as aviation and rail, have developed fatigue management tools to help managements in the work patterns of their operators. Such tools for mariners would assist shipboard crews, marine pilots, and shore managers for planning and improving work schedules. The overall aim of this paper is to determine a fatigue factor that can be applied to human performance data as a part of a software program that calculates total cognitive performance. This program enables us to establish the levels of cognitive performance in a group of marine pilots in order to test a decision-making task based on radar information. This paper addresses one of the factors that may contribute to the determination of various fatigue factors: the effects of different work patterns on the cognitive performance of a marine pilot.
