자동충돌예방 교육과 레이더시뮬레이션 교육은 STCW 협약 상 지정된 교육으로 항해사들이 항해사로 승선 시 필수적으로 수료해야 하는 교육이다. 최근에는 지정교육기관기준에 의거 교육과정 및 필요시설의 요건을 권고규정으로 두고 있어 각 교육기관은 그에 맞추어 시뮬레이션 수업을 위한 장비, FMSS(Full Mission Simulator System)을 도입하였다. 본 연구는 도입 후부터 현재까지 FMSS를 이용해서 이루어지고 있는 알파/레이더/시뮬레이션 교육이 어느 정도 효과가 있는지를 정량적으로 분석하기 위해 재학생을 대상으로 1년에 걸쳐 설문조사를 실시하였다. 그리고 분석 결과 응답자들은 수업 전과 비교하여 2.13배 능력이 향상 되었다고 답변하였다. 또한 분석 결과를 바탕으로 시뮬레이션 수업 시 발생하는 문제점을 도출하고 개선방안을 제시하고자 한다.

The performance requirements on the safety-based functionality of railway signal systems have been reinforced and the effort for enhancement of the existing system or development of the new system is being accordingly made. In particular, various technical researches on replacement or improvement of the existing ATS(Automatic Train Stop) signaling system are now in progress for better operational efficiency. In this study, the complementary points for improvement or replacement of the currently used system(i.e., ATS) will be derived in terms of operating efficiency in an integrated operating environment with the newly introduced system(e.g., ATC: Automatic Train Control). This study can contribute to derive the need for improvement of the signaling system by checking the interface problems and comparing between different systems through the analysis of real operation cases in the field. Eventually, this analysis can be applied to prevent and estimate the collision accidents can be caused by the failure of the signaling system in advance. In addition, the results can be used to provide a future direction to secure the reliability in the parallel operation by integration based on different railway signaling systems.

This study analyzed the allocation of the skipper's attention during fishing operation in the wheelhouse of a Korean coastal composite fishing vessel by using video observation. To summarize the results, the ratio of lookout, radar and GPS monitoring, which is essential for prevention of collision at sea, was significantly lower than that of other fishing operation due to the attention concentration on the work place during hauling line. In order to reduce exposure to risk of collisions due to concentration of attention to certain tasks such as line hauling, it is necessary to develop an alert system that can notify the approach of other ships or obstruction throughout the ship using information from radar or the automatic identification system. In addition, the order of attention allocation to devices and facilities obtained in this study is expected to be used as basic data for device or facility layout based on the principle of usage frequency in designing wheelhouse for coastal composite fishing vessels in the future.
