해상구조물은 그 특성상 해상에서 고립되어 있고, 액체상태 또는 가스 상태의 탄화수소 등을 다루고 있어 사고발생시 대형사고로 이어질 가능성이 크다. 이에 해상구조물에는 유엔해양법협약에 따라 500m라는 넓이의 안전수역이 설정되어 있으며 추가로 설정되는 제한 수역은 명확한 근거 없이 상이한 넓이로 설정되어 있다. 이에 본 연구에서는 선박의 조종성능 및 해상구조물에서 다루는 화물의 고유한 위험특성을 파악하여 표준화된 안전수역을 설정하는 방안을 제시하고자 한다. 이에는 국제해사기구의 조종성능기준인 선회경의 크기제한, 초기선회성능, 정지성능 등이 있다. 본 연구는 정량화된 안전수역 및 제한수역 설정 등에 대한 기준을 제시하는 데 도움을 줄 수 있을 것으로 사료된다.

The feeding habits of Largehead hairtail Trichiurus japonicus was studied using 377 specimens collected in the Yellow Sea of Korea. The specimens ranged from 4.5 to 33.7 cm in Anal length (AL). T. japonicus consumed mainly a piscivore, such as Engraulis japonicus [percent index of relative importance (%IRI) =74.1%]. We calculated the trophic level as 3.84 for T. japonicus. Fishes were the main prey items for all seasons. The main fish prey during autumn and winter was E. japonicus, whereas those during spring and summer was Larimichthys polyactis. Fishes were the main prey items for all size groups (<15 cm, 15~20 cm, 20~25 cm, ≥25 cm). T. japonicus also showed size-related dietary shift from Spratelloides gracilis and E. japonicus to L. polyactis and T. japonicus. As the anal length of T. japonicus increased, the mean number of preys per stomach (mN/ST) and the mean weight of preys per stomach (mW/ST) tended to increased (One-way ANOVA, P<0.05). Seasonal and size-related shifts in dietary composition were investigated by PERMANOVA analysis, which showed significant variations among size classes and seasons.

In 2010 the Manila Amendments established the highest practicable standards for officers and engineers. This amendments includes knowledge, understanding, skills, and proficiency required for a deck officer in terms of the BRM (Bridge Resource Management) to reduce human errors, stated in the International Convention on Standards of Training, Cerification and Watchkeeping for Seafarers (STCW). This paper proposes a proper direction to improve BRM education program in Korea. In relation to the BRM program, its contents and education method were analyzed through the satisfactions survey for cadets and the experienced officers. As a consequence, this research gives several suggestions to improve the current BRM course.

Throughout the years, cybersecurity incidents related to the shipbuilding and maritime industries are occurring more frequently as the IT industry develops. Accordingly, expertise in the information protection industry is necessary, and effective education contents on information protection are needed for this purpose. Recently, there have been more and more cases of increasing user experience by applying Metaverse technology to the educational field. Therefore, this study analyzes the existing information protection education and training and the information protection education contents in the maritime industries and proposes four directions for content development (i.e., online education and seminars, cybersecurity threat learning of virtual ships, accident reproduction, and maritime cybersecurity exhibition operation).

The diet composition of Spanish mackerel Scomberomorus niphonius, was investigated using 853 specimens collected using two-boat trawl, stow net, gill net and set net from January to December 2019 from the South Sea of Korea. The size of the specimens ranged from 25.2 to 114.8 cm in fork length. S. niphonius fed mostly on fishes. Its diets also included small quantities of shrimps, cephalopods, crabs, stomatopods, etc. Among them, Engraulis japonicus was the dominant species. The dietary composition of S. niphonius exhibited significant differences based on their size. The proportion of Trichiurus japonicus increased as body size of S. niphonius increased, whereas the proportion of E. japonicus decreased gradually. As the body size of S. niphonius increased, the mean weight of prey per the stomach (mW/ST) tended to increase significantly (one-way ANOVA, P<0.05).

The diet composition of common flying squid Todarodes pacificus was studied using 1,084 specimens collected through trawl and jigging from June 2018 to June 2020 in the East Sea of Korea. The mantle length (ML) of the collected individuals ranged from 13.6 to 31.1 cm. Todarodes pacificus is a carnivore. In the study area, T. pacificus was observed feeding mainly on fish and cephalopods, in addition to small quantities of crustaceans. The calculated trophic level value for T. pacificus was 4.10. Small individuals (ML, <18.0 cm) mainly fed on cephalopods, while intermediate (ML, 18.0-23.0 cm) and large (ML, ≥23.0 cm) individuals fed mainly on fish and occasionally on cephalopods. Overall, as the body size of T. pacificus increased, the mean weight of the consumed prey increased (one-way ANOVA, P<0.05).

The diet composition of octopus Octopus vulgaris was studied using 392 specimens collected from January to December 2020 in the coastal waters of Yeosu, Korea. The body weight ranged from 86.4 to 3,645.4 g. The most important prey item in the diet of O. vulgaris was decapods, which constituted 43.9% in ranking index (%RI). The second largest prey item was Pisces (%RI=27.9%), and cephalopods (%RI=21.8%) constituted the third largest prey item. The average trophic level of O. vulgaris was 3.97±0.59. Ontogenetic changes were significant among size classes (<400 g, 400-800 g, ≥800 g). The small size class (<400 g) mainly fed on decapods, whereas the medium (400-800 g) and large size (≥800 g) classes mainly fed on cephalopods and Pisces, respectively. The dietary composition varied significantly with season.

The purpose of this study was to verify a model for the structural relationships of safety education provided by a marine leisure sports experience center to first-aid coping skills and experience satisfaction. 307 male and female customers who used a marine leisure sports experience center located in the city of S-si, K-do Province, were investigated from June 15 to August 30, 2017. The collected data were statistically analyzed by SPSS/PC+ 20.0 and Amos 16.0. The findings of the study were as follows: First, the safety education offered by the marine leisure sports experience center was found to have affected first-aid coping skills(t=3.425, p<.001). Second, the safety education by the marine leisure sports experience center was found to have exerted an influence on experience satisfaction(t=3.751, p<.001). Third, the first-aid coping skills of the marine leisure sports experience center was found to have had an impact on experience satisfaction(t=6.781, p<.001). The measurement model for the hypothesis test in this study was found to be appropriate(GFI=.978, NFI=993, CFI=984). Given the findings of the study, more extended safety education is expected to be effective, as customers who use marine leisure sports experience centers will be able to enjoy marine leisure sports more safely and improve their quality of life when they are compulsorily required to receive safety education.
