PBL is a student-centered pedagogy in which students learn about a subject through the experience of problem solving. Marine engineer is the expert which supports the safe navigation and solves the problems could happen in independent situation as a ship. This study executed the fundamental study on the maritime training education for marine engineers using PBL. In this study, we conducted the survey on 56 students for 6 months using PBL in H university. The result showed the improvement on ability to solve the problems, interpersonal relationship, communication skill, synthetic thinking faculty and practical use of data but some students answered the complaint of the insufficient information and unacquainted learning method of PBL. This suggested the development and improvement plans for the maritime training education using PBL based on this fundamental study.

극지해역 운항선박은 주 추진시스템 및 선박 장비들이 일반 상선과 다른 경우가 많다. 따라서 극지운항 선박의 기관사들은 각종 장비 및 시스템에 친숙해져야 할 필요가 있다. 이 연구에서는 교육 및 훈련을 통해 극지 운항 선박에 승선하는 기관사관의 자질 향상을 통해 극지운항 선박의 안전운항을 도모하는데 있다. 또한, 그러한 자질 향상을 위해 필요한 Ice Engineer 교육 프로그램 방안을 모색하였다.

최근 해양사고의 통계를 분석해 보면 어선사고의 경우 2004년부터 감소하는 추세이나, 기관 사고의 경우 2004년부터 급격히 증가하는 추세로 2004년 136건에서 2006년 187건으로 50건(37.5%) 증가하였다. 2006년의 경우 전체 기관사고 중 어선이 약 96%를 차지하여 기관사고를 예방하기 위한 대책마련이 시급하다. 특히 소형어선 해양사고의 경우 약 1/3 이상이 기관사고로 안전관리 여건이 취약한 소형어선의 기관사고 예방대책 마련이 필요하며, 본 연구에서는 어선 기관의 특성, 어업기계의 사용실태, 기관손상사고 분석, 중고기관의 유통과정 등 어선 기관사용에 대한 상황을 분석하여 문제점에 대한 개선방안을 제시하고자 한다.

본 논문은 선박 기관사의 실무 능력 평가를 위한 CAI 시스템의 설계와 구현에 관한 것이다. 지금까지 실무 기관사들을 위한 평가 시험은 주로 필답 시험과 구두 시험에 의존해 왔지만, 컴퓨터를 이용할 CAI 시스템을 사용함으로써 평가에 걸리는 시간을 단축할 뿐만 아니라 효율적인 평가를 할 수 있다. 시스템의 구성은 영역 지식, 질문, 예제 등으로 구성되어 있으며 13 관련 분야에 바탕을 두고 있다. 이 시스템의 사용자는 교사, 실습생, 학생, 선박관련 전문가들이 될 수 있다. 또한 이 시스템을 Client/server 환경으로 확장하기 위하여 Oracle 7.3과 PowerBuilder 5.0을 이용한 실험적인 환경을 설계하고 대표적인 Client page를 보여주고 있다.

최근 해양사고의 통계를 분석해 보면 어선사고의 경우 2004년 575건에서 2006년까지492건으로 감소 하였으나, 어선 기관사고의 경우 2004년부터 급격히 증가하는 추세로 2004년 136건에서 2006년 187건으로 50건(37.5%) 증가 하였다. 2006년의 경우 전체 기관사고 195건 중 어선이 187건으로 96%를 차지하여 기관사고를 예방하기 위한 대책마련이 시급하다.특히 소형어선 해양사고의 경우 약 1/3 이상이 기관사고로 안전관리 여건이 취약한 소형어선의 기관사용실태를 분석한 기관사고 예방대책 마련이 필요하여, 본 연구에서는 어선기관의 특성, 어업기계의 사용실태, 기관손상사고 분석, 중고기관의 유통과정등 어선 기관사용에 대한 상황을 분석하여 문제점에 대한 개선방안을 제시하고자 한다.

Ship engine rooms have improved automation systems owing to the advancement of technology. However, there are many variables at sea, such as wind, waves, vibration, and equipment aging, which cause loosening, cutting, and leakage, which are not measured by automated systems. There are cases in which only one engineer is available for patrolling. This entails many risk factors in the engine room, where rotating equipment is operating at high temperature and high pressure. When the engineer patrols, he uses his five senses, with particular high dependence on vision. We hereby present a preliminary study to implement an engine-room patrol robot that detects and informs the machine room while a robot patrols the engine room. Images of ship engine-room equipment were classified using a convolutional neural network (CNN). After constructing the image dataset of the ship engine room, the network was trained with a pre-trained CNN model. Classification performance of the trained model showed high reproducibility. Images were visualized with a class activation map. Although it cannot be generalized because the amount of data was limited, it is thought that if the data of each ship were learned through transfer learning, a model suitable for the characteristics of each ship could be constructed with little time and cost expenditure.

The aim of onboard training of apprentice engineers in the training ship is to support and enhance fundamental knowledge and ability to have both theoretical and practical skills. This diversity in education and training improve the capability to handle problems in a crisis and build-up the feeling of confidence so they can effectively accomplish their assigned tasks in special circumstance like those onboard. Therefore this study suggests some remedies for qualitative improvement and guidance of onboard training ship for apprentice engineers to achieve the aims of onboard training to foster talented marine engineer officers with professional knowledge and leadership.

Fatigue is known to detrimentally affect a person's performance. Also, fatigue may reduce effectiveness and efficiency of marine officers and crew members. The purpose of this research is to understand on the status of the marine officers' fatigue. In this study, we carried out the questionnaire survey which is related to the marine officers' fatigue factors such as work, sleep and rest hour or period, sleepiness, casual factor, fatigue symptom, etc. The questionnaire contained 25 questions and it was distributed among 1,033 marine officers(deck officers 607 and engineers 426). The results of this survey show that marine officers' fatigue is a casual factor in marine accidents such as collisions, groundings and there was a fatigue difference between deck officers and engineers.
