In line with the United Nations' Action Plan for the First and Second World Programme for Human Rights, countries around the world are making efforts to strengthen and develop human rights education through voluntary participation and improvement of the legal system. South Korea is also trying to spread human rights education under the leadership of the National Human Rights Commission of the Republic of Korea, but there has been no significant progress so far. Moreover, it has failed to pay close attention to the human rights issues of seafarers on board. This study identified the phenomenological problems based on an analysis of domestic and international literature, and of cases of violation of seafarers' human rights. It utilized the interactivity research method to create an educational environment for improving the human rights situation of seafarers on board mixed-nationality crew vessels. In doing so, the research suggests the introduction of human rights education for seafarers and the implementation of a human rights education program in designated educational institutions as fundamental solutions to the human rights issues of seafarers, as these have been pointed out as the main cause of conflicts in mixed-nationality crew vessels.

This study aimed to determine the importance of the policies formulated through the Ministry of Maritime Affairs and Fisheries' master plan for Seafarer's policy. To confirm the importance of the Seafarer's policy, AHP analysis was conducted on the 3 main policies and 15 auxiliary policies established by the master plan for Seafarer's policy. To analyze the reliability of the survey, we investigated the inconsistency ratio of 34 respondents retrieved. We found that 25 respondents validated the reliability of the findings. The analysis showed that the policy of establishing a stable supply and demand system was the most important among the main policies for seafarers, while the policy of fostering seafarers linked to jobs was the most important one among the auxiliary policies. By group, the government recognized establishing a stable supply and demand system as a priority of policy. Dif erences were found on the fact that improving working conditions and expanding welfare were important for seafarers. This study, which analyzed the importance of the Seafarer's policy through AHP analysis, has the following implications. We established guidelines to enhance efficiency, such as budget allocation by policy according to the importance in implementing Seafarer's policies. Furthermore, our study can be used as basic data for establishing a master plan for Seafarer's policy by comparing differences in importance per group.

The term "ordinary practice of seaman" is applied to hold the responsibility of those involved in marine accidents. However, there is a concern that the responsibilities of seamen may become unclear as the ordinary practices of the seamen are imposed. In addition, the responsibility for improvement is diluted by mentioning the ordinary practice of seaman when the navigation rules stipulated in the COLREGs is clearly violated. The maritime safety investigation and tribunal system thoroughly analyzes the causes of marine accidents to prevent the recurrence of similar accidents. As one cause that does not contribute to the prevention of the recurrence of similar accidents, it would be appropriate to exclude the term "ordinary practice of seaman" as far as possible. Accordingly, I reviewed the reason for the existence of the maritime safety investigation system and ways to improve the application of the term "ordinary practice of seaman," which is recognized as a customary and an unconventional navigation rule, by examining the theories on the ordinary practice of seaman and analyzing cases of court judgments and decisions in the Korea Maritime Safety Tribunal. I also proposed a modern interpretation on the responsibility for proper and purposeful application. In addition, from the viewpoint of preventing the recurrence of maritime accidents, it is suggested that the nounized term in Korea be replaced with the descriptive term.

This study aims to propose safety culture design to ease to find out and control behavior characteristics of Korean seafarers. By empirical research of 377 Korean seafarers, the result revealed that significant characteristic of Korean seafarers was "affection to others" and custom of Confucianism affected Korean maritime society prevalently. But there were no significant differences between groups, such as rank, age, gender and sailing route with vessel type except educational background. Furthermore, this study concluded that positive reinforcement was more useful than negative reinforcement to promote safety operation of vessels. Regarding the vessel's safety management, the fact that means for vessel's safety management are linked only to the levels of educational background suggests that the efficiency of vessel's safety operation would be achieved by introducing suitable safety management system depending on the level of educational background.

The purpose of this study is to identify human factors that directly or indirectly cause ship accidents and to suggest implications based on the derived human factors. In particular, we conducted a survey on the basis of the human factors derived from the literature survey and interviews, and applied the revised importance-performance analysis (IPA) to develop implications from a comparison of two groups: seafarers and shipping operations managers. Data were collected from 159 practitioners in the Korean shipping industry. The analysis structure consisted of five major factors with 20 components, including unique factors related to ship and shipping management companies, personal competence, in-vessel organization, and personnel's health, as well as social factors. The result of the IPA analysis indicates that in-vessel organization is the most urgent and major factor for improvement. Some differences exist in the components that should be improved between the two groups. For the seafarer group, an increase in unskilled onboard crew affected sustainable safety activities, thus implying an area of preferential improvement regarding the in-vessel organization factor. However, for the shipping operations managers group, the difference in recognizing safety standards among the crew members on board and the ability to communicate with other crew members should be improved first relative to in-vessel organization factors. The personnel's health factor was identified to be of low importance in both groups. Finally, the importance of improving the safety consciousness level according to the safety education and training implementation for seafarers on board was different for the two groups.

COVID-19 is threatening the safety of ships and seafarers by delaying seafarer rotation. Shipping companies and governments have a blindspot in case of the onboard environment of seafarers. An effective, alternative plan should be devised to eliminate the possibility of human accidents in an emergency that threatens the safety of seafarers. According to the survey of former and current seafarers, the most important factor in boarding life was safety, and the most necessary thing during emergencies was to secure smooth seafarer rotation rather than improve wages and welfare. By analyzing the major routes of national shipping companies by continent, ports with a large number of calls and a high Air Connectivity Index were selected as the base port. In addition, the route was designed for effective, domestic seafarer rotation during international shipping. Other countries must be consulted to establish a travel route linking ships, ports, and airports for the safe return of sailors to their home countries during an emergency. In addition, it is necessary to work together for the seafarers who are in trouble of seafarer rotation through cooperation with the International Maritime Organization(IMO). Starting with this, the government should have a monitoring system for the return and non-return routes as well as the number of seafarers on board. If such a system is established, it will be able to determine the response direction of our country's policy in case of an emergency. Along with the shipping company's ef orts to improve the treatment of seafarers, national and social attention will be needed to review domestic laws and improve awareness about seafarers.

자율운항선박의 도입이 가시화됨에 따라 자율운항선박의 운항을 관리·감독하는 원격운항자의 운항능력에 대한 관심도 증가하고 있다. IMO에서는 원격운항자의 상시 모니터링과 비상시 원격지원을 기반으로 하는 자율운항 선박모델을 제시하고 있다. 특히 선박의 자동화 시스템으로 대응할 수 없는 복잡한 상황에 직면할 경우 해당상황을 해결하기 위해 원격운항자의 판단력과 지식이 요구되는 상황이 발생할 수 있다. 따라서 원격운항자는 선체와 주변 상황을 원격으로 인식하는 상황인식능력이 필요하며, 원격운항자의 상황인식능력은 기존 항해사의 상황인식능력과는 상이한 부분이 존재할 수 있다. 본 연구에서는 자율운항선박의 도입으로 인해 발생하는 운항환경의 변화에 따라 원격운항자에게 요구되는 상황인식 요구사항을 분석하고 이를 기존 선원의 상황인식 모델과 비교하여 자율운항선박의 안전한 도입을 위한 기초자료로 활용하고자 한다.

To maintain and improve seafarers oral health, I investigated and analyzed the oral health status of seafarers: who are safety training at Korea Institute of Maritime and Fisheries Technology located in Busan. The results of the investigation and analysis are as follows: Two times of brushing teeth a day occupied $51.0\%$ the largest percentage, mixed brushing method was the highest as $39.0\%$, $64.2\% of respondents have recieved teeth scaling. Two or three of times snack intake per day occupied $62.6\%$ the largest percentage. Based on the objects' answer on oral status, the persons answered that my oral status is 'good' $25.9\%$ 'bad' $38.3\%$ occupied The persons with a decayed tooth occupied $78.1\%$ and as for the subjective symptoms of oral disease, $25.6\%$ of respondents answered that I felt sensitivity. Intraoral discomfortable symptoms in the respect of each age, under forty age had dental decay, over forty age had sensitivity of teeth. The more has a intake snack, the more has an oral disease and oral decayed tooth. As a whole of the above results in order to control oral health of the seafarers reasonably, time and economic limiting factors must be solved in the first. In planning oral health education, practicability should be emphasized especially.

이 연구는 원격검사의 한 방법으로서, 특히 자율운항 선박에서 컴퓨터비전을 이용한 영상처리를 통한 원격 검사방법에 관한 것이다. 자율운항 선박은 자율화의 정도에 따라 다르지만, 선원이 승선하지 않거나 최소한의 선원만 승선하는 선박이므로 선박의 검사방법에 변화가 필요한 실정이다. 따라서 컴퓨터비전을 이용한 영상처리에 대한 이론적 배경을 바탕으로 원격검사 항목 중에서 아날로그 게이지의 정량화에 필요한 영상의 전처리 방법에 관한 연구이다. 아날로그 게이지의 정량화를 위해서 사용한 방법은 흑백처리, 가우시안필터, 임계화처리, 모폴로지 연산이다. 이 연구를 통하여 영상의 전처리 결과 배경과 객체를 비교적 명확하게 분류할 수 있었으며, 영상처리 과정 중 추가로 발생한 잡음을 효과적으로 제거할 수 있었다. 이를 통하여 영상에서 주된 객체인 지시바늘과 눈금판의 숫자를 인식에 필요한 이미지 전처리 방법을 제시하였으며, 나아가 컴퓨터 비전을 이용한 원격검사 방법은 아날로그 게이지뿐만 아니라 비상차단밸브, 통풍폐쇄장치, 고정식 소화장치 등 여러 방면에서 사용될 것이라 기대한다.

In recent years, use of machine automation is rising in the industry. Ships also obtain machine condition information from sensor as digital information. However, on ships, crew members regularly surveil the engine room to check the condition of equipment and their information through analog gauges. This is a time-consuming and tedious process and poses safety risks to the crew while on surveillance. To address this, engine room surveillance using an autonomous mobile robot is being actively explored as a solution because it can reduce time, costs, and the safety risks for crew. Analog gauge reading using an autonomous mobile robot requires digitization for the robot to recognize the gauge value. In this study, image processing techniques were applied to achieve this. Analog gauge images were subjected to image preprocessing to remove noise and highlight their features. The center point, indicator point, minimum value and maximum value of the analog gauge were detected through image processing. Through the straight line connecting these points, the angle from the minimum value to the maximum value and the angle from the minimum value to indicator point were obtained. The obtained angle is digitized as the value currently indicated by the analog gauge through a formula. It was confirmed from the experiments that the digitization of the analog gauge using image processing was successful, indicating the equivalent current value shown by the gauge. When applied to surveillance robots, this algorithm can minimize safety risks and time and opportunity costs of crew members for engine room surveillance.
