The quantitative increase in maritime transport for domestic and foreign trade is one of the main reasons for the increase in marine pollution accidents. Despite the implementation of relevant laws in each country to prevent and mitigate marine pollution accidents caused by ships, human negligence (carelessness, intention, etc.) by ship workers has been reported as the biggest cause of marine pollution accidents. One of the most effective ways to reduce marine pollution accidents caused by ships is to reduce human negligence through systematic education and training of ship workers. Therefore, this study aimed to review the appropriateness of the statutory education and training curriculum for ship marine pollution prevention managers in accordance with domestic laws and regulations such as the 「Marine Environment Management Act」 and suggest improvement measures. To this end, we compared and analyzed the legal training·general education courses related to the prevention of marine pollution and marine disasters in Japan, where the laws and systems are similar to Korea, and investigated the cases of legal training for experts in land pollution prevention in Korea.

The diet composition of skinnycheek lanternfish, Benthosema pterotum were collected by bottom trawl net in the South Sea of Korea during 2021 (February, May, August, and November) and 2022 (February, April, August, and November). The size of the specimens ranged from 16 to 73 mm in total length. B. pterotum were mesopelagic carnivores that mainly consumed euphausiids and copepods. Its diets included small quantities of amphipods, shrimps, mysids, etc. We calculated the trophic level as 3.16 for B. pterotum. The individuals of small size class (<40 mm) fed mainly on copepods. In the next size classes (40~45 mm, 45~50 mm, 50~55 mm), copepods' proportion decreased and euphausiids increased. In the largest class (55~60 mm and ≥60 mm), the proportion of euphausiids' decreased, and shrimps increased. As the body size of B. pterotum increased the mean weight of prey per stomach (mW/ST) tended to significantly increase (One-way ANOVA, P<0.05).

Total 158 Conger myriaster were examined and the range of Preanal length (PaL) was 8.2~40.1 cm and average Preanal length was 17.3 cm. Proportion of the empty stomach was 30.4% and individuals, which the prey items were found in stomach, were 110. The most important prey component in the diets of C. myriaster was Pisces that constituted 54.4% in %IRI (Index of relative importance). Engraulis japonicus was the most important prey component in Pisces. Macrura was the second largest prey component and Crangon hakodatei was the most important prey component in Macrura. The result of analysis in ontogenetic changes significantly exhibited among three size classes (<15.0 cm, 15.0~20.0 cm, ≥20.0 cm). The proportion of Macrura decreased as increasing body size, whereas the consumption of Pisces increased gradually. As body size of C. myriaster increased, the mean weight of prey per stomach (mW/ST) increased (one way-ANOVA, P<0.05).

지난 30년간 국내의 해양 시뮬레이터는 기능적인 개선 뿐만 다양한 부분에서 비약적으로 발전해 왔다. 그러나 국내에서는 대부분 해양 시뮬레이터를 외국산 장비를 도입하여 해기사 및 도선사의 교육, 훈련용과 항만개발 분야에서 결과 분석을 통한 안전성 평가의 목적으로 사용 되어왔다. 그러나 향후, 국내 해양 시뮬레이터 나아갈 방향은 오랜 운영경험의 토대로 해양 산업에 융합하기 위하여 연구 개발을 통해 국산화 기술 확보하여 국제적으로 경쟁력을 높일 뿐만 아니라 국내 해양 산업을 육성에 기여 할 수 있도록 검토해보고저 한다.

선원의 다국적화가 이루어짐에 따라서 해기사들의 외국인 선원관리에 대한 리더십이 날로 중요시 되고 있다. 효과적인 리더와 리더십은 교육을 통해 양성되고 향상될 수 있다. 본 연구는 선원의 다국적화가 증가되고 있는 현실을 감안하여 해기사 양성 대학의 리더십 교육체계 정립을 위한 기초연구로서, 학생들이 실습시 경험한 자료를 토대로 설문 분석을 하였다. 향후 확대된 자료의 수집과 심층분석을 통해 지속적으로 심층 연구를 하고자 한다.

IMO에서 규정하는 모든 교육 및 훈련을 이수한 전문 해기인력이 매년 배출되고 있지만, 해양사고의 발생은 끊이지 않고 있다. 이는 해양사고를 대처하는 해기사의 위험상황 대처 능력이 크게 개선되지 않았다는 점을 의미한다. 공통적으로 해기사에게 제공되는 교육 및 훈련뿐만 아니라 해기사 개개인의 위험요소를 파악하여 해당 위험 요소에 대한 매뉴얼을 제공할 수 있는 모델이 개발되면 해양사고를 대처할 수 있다. 이러한 모델을 개발하기 위하여 모델 구축에 필요한 데이터베이스(Data Base, D/B)가 필요하다. 이러한 D/B는 모델에 활용할 수 있도록 숫자로 표기된 것이어야 한다. 본 연구에서는 해양안전심판원에서 제공하는 해양사고 데이터를 수집, 분석하여 해양사고 예방을 위한 모델에 활용할 수 있는 해양사고 수량화 D/B를 구축하는 방법에 대하여 고찰하였다. 1차적으로 해양사고 수량화 D/B를 구축하였으나, 이의 유용성이나 목적에 적합한 D/B의 규모 등에 관한 연구는 추후에 계속 되어야 한다.

In this study, an expert survey was conducted using the Delphi technique to select items and indicators for evaluation before installing educational facilities in the marine fisheries safety field, in which the educational infrastructure gap between regions is wide. Seven indicators were selected as geographic, social, and administrative factors. In order to objectively evaluate each indicator, evaluation indicators that could be evaluated using public data such as the "Comprehensive National Balanced Development Information System" and "National Statistical Portal" were developed. The Analytic Hierarchy Process (AHP) method was applied to select the weight for each indicator, resulting in 10 most important influencing factors on the selection of the location of educational facilities of the Marine Fisheries Safety Education Facilities: the distribution of marine officers, access to high-speed railways, the number of small ships less than 5 tons, access to highways interchange, the distribution of fishing boats, the close relationship of related industries, the planned new port, the distribution of commercial ports, the number of marine leisure riders, and the availability of long-term land leases in local government councils. The location evaluation index of marine and fishery safety education facilities developed in this study can be used to evaluate each region using national public data, and has the advantage of enabling objective evaluation. Therefore, it is judged that this evaluation index can be used to verify the feasibility of installing marine fisheries safety education facilities as well as other marine-related facilities.

Total 418 Yellow Croaker Larimichthys polyactis were examined and the range of total length (TL) was 12.0~27.5 cm and average total length was 19.6 cm. The most important prey component in the diets of L. polyactis was Pisces that constituted 46.5% in %IRI (Index of relative importance). Euphausiacea was the second largest prey component. The result of analysis in ontogenetic and seasonal changes significantly exhibited. The proportion of Pisces increased as increasing body size, whereas the consumption of Macrura decreased gradually. The diets also were different among seasons, with the difference particularly being evident between warm (summer and autumn) and cold (winter and spring) seasons. Permutational multivariate analysis of variance (PERMANOVA) revealed significant dietary differences by seasons (P=0.001).

해양사고의 원인을 파악하기 위해 해양사고 관련자의 특성(연령별, 해기면허별)을 분석해보면, 상급 항해사가 관련된 사고는 33.5%이며, 하급 항해사가 관련된 사고는 64.1%로 항해사의 급수별로 해양사고 관련 비율에 차이가 있으며, 특히 하급 항해사가 관련된 해양사고의 비율이 상급 항해사와 비교할 때 상대적으로 높았다. 이러한 하급해기사 면허 소자자의 경우 그 동안 상급 해기사 면허 소지자에 비해 해기교육을 이수할 기회가 적었으므로, 기초적인 부분에 대한 교육이 먼저 이루어져아 할 것으로 판단된다. 그러므로, 이러한 기초적인 부분에 대한 교육을 수행할 수 있는 사무실 환경에 보급이 가능한 보급형 시뮬레이션 시스템 개발이 필요하다. 이에, 하급 항해사의 과실에 의해 발생되는 사고를 줄일 수 있도록 비교적 영세한 해운업체에도 보급이 가능한 하급 해기사 평가용 시뮬레이션 시스템을 개발하였다.

The number of ships using liquefied natural gas (LNG) as fuel is increasing to respond to the International Maritime Organization's (IMO) air pollutant emission regulations. At the same time, the need to expand LNG bunkering infrastructure for stable fuel supply and demand for ships is emerging. LNG bunkering is carried out in three ways: truck to ship (TTS), pipe to ship (PTS), and ship to ship (STS). In foreign countries, all three methods are being carried out, but in Korea, LNG bunkering is carried out only with the TTS method owing to the lack of infrastructure. LNG bunkering is a high-risk operation. For safe bunkering operations, the competence of the workers is extremely important, and a professional training course is required to strengthen the competence. This study was conducted to design training contents for LNG bunkering workers for fostering LNG bunkering experts and performing safe and systematic bunkering work. To this end, the current status of LNG-fueled ships and bunkering was identified, and related domestic and abroad educational contents were analyzed. In addition, opinions on the importance of educational contents were collected through expert questionnaires. Consequently, we designed training contents suitable for various training targets and divided them into basic and advanced training courses, with a duration of 4 days, and proposed. Based on the designed training contents, if additional research is conducted by sufficiently reflecting Korea's bunkering environment, it will be of great help to improve the competence of LNG bunkering workers and to foster human resources.
