  • We aim to propose the prediction modeling method of ship's position with extracting ship's trajectory model through pattern recognition based on the data that are being collected in VTS centers at real time. Support Vector Machine algorithm was used for data modeling. The optimal parameters are calculated with k-fold cross validation and grid search. We expect that the proposed modeling method could support VTS operators' decision making in case of complex encountering traffic situations.

  • A key element of a successful search and rescue is the correct prediction of the target location. In this paper, new computer models for drift prediction are suggested from the analysis of several methods currently used in other countries. Depending on the availability of the environmental data, users may select a model between the modified versions of U.S. Coast Guard CASP and FLENUMWEACEN SAR. Targets include boats, life rafts and person in water. Life rafts and boats are further classifed. New models are tested and compared with the limited number of field experimental results.

  • The ocean provides with not only the global environment and ecology, which is essential for human beings survival, but also various resources for human beings prosperity. The ocean security is to secure and keep the benefits that the ocean provides with to human beings. It is essential to keep enforcement measures for the ocean security. Major marine countries are challenging to secure ocean environment and resources since UNCLOS. The utmost policy priority should be given to the ocean security in Korea.

  • Should the Korea Maritime Police Agency (KMPA) be a comprehensive, multi-functional organization for a unique on-scene service at sea, as in the case of the U.S. Coast Guard, or should it be simply a water police agency, confining its mission only to law enforcement? The argument about enlarging or limiting KMPA's function has been and will be repeated. In this paper, Lee Sangjib highlights the internal and external issues facing KMPA, stemming partly from deficiencies of its struggles for advancement of the organization and partly from shortcomings of political support for it. In this regard, he urges KMPA to practise a scientific management system for maximizing cost-effectiveness of its administrative resources and for maintaining its identity and characteristics as a lead maritime agency. In addition, he also suggests that KMPA adopt the Total Quality Management System for quality improvements in services and greater efficiency in its organization structure to meet the future competition in the changing political and legal environment. He further recommends the proactive, non-regulatory 'Prevention Through People' program, pioneered by the U.S. Coast Guard, as a way of changing KMPA's existing lopsidedly legalistic culture. He concludes by providing a 6-point vision statement for KMPA from the standpoint of favoring enlarging the function of KMPA.

  • Maritime transportation is going to transfer to alternative fuels as a result of the worldwide demands toward decarbonization and tougher maritime emissions regulations. Methanol is considered as a potential marine fuel, which has the ability to reduce SOx and CO2 emissions, reduce climate change effects, and achieve the objective of green shipping. This work proposes and combines the innovative combination system of direct methanol solid oxide fuel cells (SOFC), proton exchange membrane fuel cells (PEMFC), gas turbines (GT), and organic Rankine cycles (ORC) for maritime vessels. The system's primary power source is the SOFC, while the GT and PEMFC use the waste heat from the SOFC to generate useful power and improve the system's ability to use waste heat. Each component's thermodynamics model and the combined system's model are established and examined. The multigeneration system's energy and exergy efficiency are 76.2% and 30.3%, respectively. When compared to a SOFC stand-alone system, the energy efficiency of the GT and PEMFC system is increased by 19.2%. The use of PEMFC linked SOFC has significant efficiency when a ship is being started or maneuvered and a quick response from the power and propulsion plant is required.

  • Purpose: This study aimed to analyze the jobs of paramedics who are diversifying by deriving duties in accordance with occupational group-related laws, although they are not directly specified in the job description of paramedics or the Emergency Medical Act. Methods: This study selected four paramedics who randomly extracted participants that submitted consent to participate between March 2023 and October 2023. Their occupational groups were the Korea coast guard and air rescue, health centers, and industries; they met on September 19, 2023, and directly transcribed the recorded contents through a three-and-a-half-hour focus group interview for analysis. Results: In the results, although the job description was not directly specified in the job description or emergency medical law, five areas of work applied to practice were derived: "rescue," "administration," "education," "industry," and "tactical." Conclusion: To expand jobs according to the diversification of the occupational field of paramedics, job analysis of paramedics belonging to various occupations is required.

  • The several sacrificial rites foods in east coast areas Kyungpook province, Pohang, Youngduk, and Uljin, were surveyed. For the anniversary menorial service, the food items in these reas were mainly rice(Bab'), soup(Guk'), stew(Tang'), fruits, neats and fishes, alcohol which are the typical food items for any other area in Korea. In this east coast area, the seaweed was used more often than in inner land area for this rite food. Four kinds of rice cake(Ddeok' or Pyun') were surveyed for this rite. For the baked food item(Geuk'), the fish squid and the Alaska pollack were used frequently for Geuk'. For the fruits dishes, 3 items were the basic. Tang' which was made with the various fishes, were used very frequently. For the religious memorial service for god to guard the household, the displayed food items were different from depending on the type of the god to guard the household, however, the general display of the food items was almost the same as in land area. For the winter sacrificial rite, the boiled rice(97%) and Bakpyun' was used mostly for the Ddeok'. For the Guk', bean sprout was used mostly, however, the seaweed soup was also used(7%). The fish Tang' was the most used one(35%). For young-deung-je', which implied th safe guard of the household, most of the food items are similar to those of the normal sacrificial rite, however, the fishes which were not fishy were used. The housekeeper arranged the rite to catch a large amount of the fishes and to hope the wellbeing of the household, Poong-yer-je is so called as Byul-sin-gud'(a practice of an exorciser). The food items for this Poong-yer-je' were almost similar to those of the winter sacrificial rite, however, Geulpyun' was mostly used for the Pyun'. In addition that, the red-bean Si-ruddock', Baekpyun', and Yung-ddock'(a dragon cake) were used for this rite, At the end of the sacrificial rite, Yong-ddock' was served to the dragon king which was believed in sea.

  • This paper develops a risk index based on an indicator of risk assessment in terms of coastal activity location and accident type. The risk index is derived from a formula which adds the consequence of failure to a vulnerability value, then subtracts the mitigation value. Specifically, the consequence of failure is the number of casualties in coastal activity locations. An indicator of vulnerability refers to coastal environment elements and social elements. A pointer of mitigation includes managerial and organizational elements that indicate the capabilities of coastal activities. A risk rating of coastal activity location is found from a risk matrix consisting of the accident location and type. The purpose of this study is to prevent accidents at coastal activity locations by allowing the Coastal police guard to monitor effectively and inform visitors of potential risks.
