        This study evaluates the occupational accident risks of anchovy boat seine fishery in Korea. Using Bayesian network modeling within the framework of the Formal Safety Assessment (FSA) proposed by the International Maritime Organization (IMO), data from 508 accident compensation claims between 2018 and 2022 were analyzed. Accidents were categorized into processes (sailing, fishing, maintenance, loading/unloading, and catch processing) and risk factors (hull and working environment, fishing gear and equipment, machinery and equipment, weather and external conditions, and processing equipment). The analysis revealed significant risks associated with fishing processes and hull-related factors. Fishing accounted for 36.42% of all accidents with trips/slips being the most frequent type (29.13%). Bayesian network analysis showed that trips/slips accidents during fishing posed the highest risks (0.001100). The risk of fishing operations was 4.60 times higher than sailing and 30.00 times higher than loading/unloading. The findings indicate that risks vary significantly depending on the processes and risk factors involved. As risk assessments mandated by the 2025 revision of Korean fishing safety laws are expected to remain simple and qualitative, this study underscores the necessity of incorporating quantitative approaches to enhance the reliability and effectiveness of safety management practices.

        This study analyzed the Conservation and Management Measures (CMMs) related to fishing operations using Fish Aggregating Devices (FADs) among the measures implemented by Regional Fisheries Management Organizations (RFMOs) overseeing tuna purse seine fisheries. Additionally, we analyzed the FADs fishing status by sea area and examined the sustainable tuna purse seine fishing using FADs. Significant variations were observed in the number, materials, structure, and timing of FADs deployments, which were influenced by the fishing ground environment and methods in each ocean. These variations resulted in corresponding differences in the CMMs. However, all oceans required the use of non-entangling FADs and recommended biodegradable materials to mitigate marine pollution and bycatch of protected species. An analysis of FADs usage based on field interviews revealed that the total number of FADs deployed across all oceans in 2023 reached 142,020 sets, an increase of approximately 18% compared to 120,680 sets in 2013, despite the enforcement of CMMs by each RFMOs aimed at gradually reducing FADs fishing to promote sustainable fisheries. Each RFMOs aims to gradually reduce FADs fishing rates and ultimately achieve sustainable fisheries. Therefore, to achieve sustainable tuna purse seine fisheries using FADs, prioritizing research on the biodegradable materials used in FADs construction is essential. Furthermore, strict adherence to principles concerning the quantitative use and retrieval of FADs is deemed necessary.

        This study aimed to investigate the catch selectivity characteristics related to the mesh arrangement of the codend in bottom trawl. Sea trials were conducted using the covered codend method from January 16 to 17, 2024, off the southern coast of Gyeongsangnam-do, focusing on the side panels of diamond and square mesh codend. A probit model was used in the selectivity analysis to estimate retention probability curves for sea pike comparing the  , , and  selectivity lengths, the selection range ( ), and the corresponding  and  values. The estimated 50% selection lengths were 23.82 cm for the diamond mesh and 25.20 cm for the square mesh whereas the corresponding selection ranges were 5.23 cm for the diamond mesh and 3.71 cm for the square mesh. The  and  values for the square mesh were lower, at 35.91 and 36.71, respectively, compared to 37.65 and 38.45 for the diamond mesh. Additionally, the retention probability at a fork length of 15 cm was lower for the square mesh than for the diamond mesh. These findings provide practical insights for gear design while contributing to the reduction of bycatch and small size fish catches in bottom trawl.

        This study quantitatively analyzes risks of industrial incidents to fisher on overseas tuna purse seiners and long liners. A Bayesian network is employed to analyze 478 cases of industrial incidents, comprising 401 cases from purse seiners and 77 cases from long liners, reported from 2019 to 2022. The highest risk of industrial incidents on purse seiners is attributed to diseases. Excluding diseases, risks are the highest during fishing: 5.31 times higher during catch handling, 2.05 times higher during maintenance, and 2.38 times higher during loading and unloading. The risk of industrial incidents caused by the hull is 9.50 times higher than those caused by fishing gear, 4.59 times higher than those caused by machinery, and 3.61 times higher than those caused by the caught fish. Among the types of industrial incidents, slips are the highest: 2.58 times higher than industrial incidents caused by being bump, 3.74 times higher than those caused by hit, and 3.94 times higher than those caused by imbalance and overexertion. For long liners, most industrial incidents are concentrated in diseases, with dental, musculoskeletal, skin, and respiratory diseases being the primary types of industrial incidents identified. This study aims to propose reduction measures for reducing the high-risk form of industrial incidents, specifically slips, and to present health management strategies for preventing diseases among fisher on overseas tuna fishing vessels. By addressing these aspects, this study seeks to contribute to the safety and sustainability of the overseas tuna fishing industry.

        본 연구는 국제사회에서 심각한 인권침해국으로 비난받고 있는 북한이 여성에 대한 모든 형태의 차별철폐에 관한 협약(여성차별철폐협약)을 이 행하는 국제적 및 국내적 의도를 분석한다. 북한은 2001년 2월 여성차별 철폐협약에 가입했고 이듬해 1차 국가보고서를 제출했다. 2016년 2-4차 통합 국가보고서, 2021년에는 지속가능발전목표(SDGs)의 성평등 현황을 포함한 자발적국가리뷰를 포함해 제출했다. 국내법과 제도 등을 통해 인 권 기록을 개선하는 모습을 보였다. 국제규범이 국가의 국제규범 준수에 영향을 줄 수 있는 강압과 문화적응의 기제를 평판 개념과 연결하여 북 한이 국제여성규범을 이행한 의도를 분석한다. 우선 국제적으로는 북한 인권조사위원회의 보고서 제출 이후 북한에 대한 국제적 비난에 대응하 고 국제인권규범 이행으로 평판 우산을 만들어 유엔전략계획 등 국제기 구와 상호협력을 증진하기 위함이었다. ‘여성’ 규범은 기존 정책을 크게 바꾸지 않고도 국제규범을 실천하고 있다는 표현적 효과로 평판을 얻을 수 있는 분야였다. 국내적으로는 시장화 이후 여성의 지위 변화에 대응 하고 자신을 비난하는 국가들을 여성 권리 침해국으로 규정하여 북한을 국제규범을 준수하고 여성 권리를 보호하는 국가로 체제를 정당화하기 위함이었다.

        The model ship of this study, the Baek-Kyung fisheries training ship of Pukyong National University, has a length between perpendiculars of 85 meters, making it not subject to the IMO maneuverability standards. However, understanding the maneuvering characteristics of the vessel is essential for safe navigation. In this regard, this study was conducted to analyze the results from the sea trials of the model ship conducted in accordance with the IMO maneuverability standards. The results of the turning tests met the standards well while in the zig-zag tests, the first overshoot angle exceeded the standard in the 10°/10° test; however, such results met with a difference of 1.8° in the 20°/20° test. Additionally, using the course-stability discrimination formula, the calculated value was -0.0051, indicating unstable course-stability. The results of the stopping tests met the standards well. It is hoped that the analyzed maneuvering characteristics of the model ship from the study results will contribute to the safety of ship navigation.

        This study aimed to quantitatively analyze the risk using data from 329 safety accidents that occurred in aquaculture fisheries management vessels over the recent five years (2018-2022). For quantitative risk analysis, the Bayesian network proposed by the International Maritime Organization (IMO) was used to analyze the risk level according to the fishing process and cause of safety accidents. Among the work processes, the fishing process was analyzed to have the highest risk, being 12.5 times that of the navigation, 2.7 times that of the maintenance, and 8.8 times that of the loading and unloading. Among the causes of accidents, the hull and working environment showed the highest risk, being 1.7 times that of fishing gear and equipment, 4.7 times that of machinery and equipment, and 9.4 times that of external environment. By quantitatively analyzing the safety accident risks for 64 combinations of these four work processes and four accident causes, this study provided fundamental data to reduce safety accidents occurring in aquaculture fisheries management vessels.

        This study employs Bayesian network analysis to quantitatively evaluate the risk of incidents in trap boats, utilizing accident compensation approval data spanning from 2018 to 2022. With a dataset comprising 1,635 incidents, the analysis reveals a mortality risk of approximately 0.011 across the entire trap boat. The study significantly identifies variations in incident risks contingent upon fishing area and fishing processes. Specifically, incidents are approximately 1.22 times more likely to occur in coastal compared to offshore, and the risk during fishing processes outweighs that during maintenance operations by a factor of approximately 23.20. Furthermore, a detailed examination of incident types reveals varying incidence rates. Trip/slip incidents, for instance, are approximately 1.36 times more prevalent than bump/hit incidents, 1.58 times more than stuck incidents, and a substantial 5.17 times more than fall incidents. The study concludes by providing inferred mortality risks for 16 distinct scenarios, incorporating fishing areas, processes, and incident types. This foundational data offers a tailored approach to risk mitigation, enabling proactive measures suited to specific circumstances and occurrence types in the trap boat industry.

        We analyzed risk factors of coastal gillnet fishers during fishing process and considered work safety measures to reduce safety accidents during fishing using a UWB (ultra wideband) based positioning system. The static position accuracy of the UWB based positioning system was 45 cm. When entering a port, there is a risk of falling overboard. When casting a net, there was a risk of falling overboard due to being hit by fishing gear or guards, or getting caught in a buoy line or sinker line. When hauling a net, there is a risk of getting caught between fishing gear and net hauler, and the risk of musculoskeletal disorders due to repetitive work over a long period of time. Most safety accidents during work on fishing boats are blamed on human errors of the fisher and skipper, but safety accidents occur due to a mixture of mechanical and equipment factors, work and environmental factors, and management factors in addition to human errors. Therefore, the 4E were presented as countermeasures against the 4M, which are causes of safety accidents, and the proposed measures were used to identify risk factors for operation process, comply with work safety rules, and ensure the wearing of personal protective equipments. We need to reduce safety accidents during work by making it part of our daily routine. These research results can be used in the future for optimal placement of fishing gear and fishing nets in other coastal industries where safety accidents occur frequently.

        This paper compares the language policies implemented in Korea and Japan based on the Korean Language Basic Law and the Promotion of Japanese Language Education Act. The research examines the purpose, background, key policy agencies, measures taken, and achievements of legislation in order to gain insight into the philosophy behind and direction of national language education as a foreign language. The findings are summarized as follows: Firstly, there are differences between Korea and Japan in terms of the process and background of enacting policies for native language education as a foreign language. But in both cases, the legislation regarding language policies carries significant meaning as it imposes obligations on responsible bodies. Secondly, there are points worth noting regarding the content aspect that constitutes educational curricula. Within educational curricula frameworks lie ideological values inherent within them. Both Korean and Japanese languages’ educational curricula as foreign languages fundamentally embrace multilingualism and interculturalism.

        The aging fishery training vessels from the past have mostly been decommissioned, and many universities are introducing state-of-the-art large fishery training vessels. The purpose of these training vessels is to train marine professionals and above all, safety to prevent marine accidents should be of utmost priority as many students embark on the vessel. This study estimated the impact of the hydrodynamic interaction forces acting on the model vessel (fishery training vessel) from the bank when the vessel pass near the semi-circle bank wall in various conditions through the numerical calculation, especially concerning maneuvering motions of the vessel. For estimation, variables were mainly set as the size of the semi-circle shape, the lateral distance between the bank and the model vessel, and the depth near the bank. As a result, it was estimated that, in order for the model vessel to safely pass the semi-circle bank wall at a speed of 4 knots, the water depth to the vessel draft ratio should be 1.5 or more (approximately 8 m of water depth), and the lateral distance from the semi-circle bank wall should be 0.4 times the model vessel’s length    or more (a distance of 34 m or more). Under these conditions, it was expected that the model vessel would pass without significantly being affected by the bank wall.

        Recently, universities of fisheries and institutions related to fisheries are actively carrying out a project to build new fisheries training ships. These new fisheries training ships are significantly larger in size and longer in length than the previous ships. In addition, these new ships basically have space that can accommodate more than 100 crew and passenger. On the other hand, they are excluded from IMO maneuverability evaluation since the size of these ships are still less than 100 m in length (LBP). These results have had an impact on the study of maneuverability of fishing vessels including the fisheries training ships. Against these backgrounds, the authors conducted a study to estimate the maneuvering characteristics of fisheries training ship Baek-Kyung according to depth in order to prepare a maneuvering characteristic index that enables the large fisheries training ships to navigate more safely using a modified empirical formula. It was confirmed that the maneuvering characteristics of Baek-Kyung changed significantly as the values of the hydrodynamic force coefficients changed as the water depth gradually decreased from around 1.5 (approx. 8 m in depth) of the ratio of the water depth to the ship draft. The results of this study will not only help navigators understand the maneuvering characteristics of Baek-Kyung, but also serve as an indicator when navigating in shallow water. In addition, the accumulation of these results will serve as a basis for future study on maneuverability of fishing vessel types.

        This study quantitatively evaluated size selectivity for three netting shapes (T0; regular, T45, T90) and hanging ratio (35%, 70%) of T0 netting used for trawl codend. The size selectivity experiment was performed in a tank using a cube experimental model with a length of 50 cm on one side and 389 experimental individuals, jack mackerel (Trachurus japonicus). In the selectivity analysis, a selectivity curve was created based on the selection ratio using a logistic function, and the 25%, 50%, and 70% selection length and selection range  were obtained. The T0 netting was 19.54 cm when the 50% selective length, which is a selectivity evaluation index, had a hanging ratio of 35%, a selection range of 0.51 cm, and 22.70 cm and 3.08 cm for the hanging ratio of 70%. The T45 netting was 24.34 cm and 2.13 cm, and the T90 netting was 23.51 cm and 2.84 cm. The results of the T45 netting and the T90 netting are similar, and the 50% selection length and selection range were relatively larger than the T0 netting. There was a significant difference in the correlation between the circumference of the inner circle of the mesh by the shape of the netting and the body girth of the experimental individual (Pearson test,      ). There was no significant difference in the correlation between the selection ratio by the T0 netting, T45 netting, and T90 netting with a 70% hanging ratio (one-way ANOVA,   ). The results of this study showed that selectivity such as T45 netting and T90 netting appeared when the hanging ratio, which maximizes the area of T0 netting, was maintained at 70%.

        In this study, samples of sea anchor canopy cloth mainly used in Korean jigging fishing vessels were collected and tested for performance evaluation. The canopy cloth of sea anchor is a basic element of form composition that is known to have the greatest influence on anchor performance. In order to evaluate the performance of sea anchor canopy cloth, five types of samples were tested for new metric count, tensile strength, water vapour transmission rate and drying speed according to the national standard (KS), and some correlations were identified. As a result of the test, the new metric count of cloths was 335.5-443.4 denier in warp and 217-447.6 denier in weft, and the minimum tensile strength was 860 N in warp direction and 430 N in weft direction. The apparent number and tensile strength of cloth were proportional, the water vapour transmission rate of the sample was 206.8 g/m 2 h, and the drying speed was 90-100 min. This study partially confirmed the performance evaluation based on speculation by the standard test method, and further research is needed on the clear relationship between the research results and the performance of the sea anchor.
