4. A framework for improving the Marine Spatial Data System in the Republic of Korea
摘要： The main objective of this paper is to:(1)analyze and compare the present Marine Spatial Data(MSD)system in the Republic of Korea(ROK)with those of other countries,(2)identify the legal vacuum of the Act on Marine Spatial Planning(MSP)and Management,(3)propose a solid legal framework for the MSD system. By exploring some key significant points in the MSD system,the paper revealed a lack of a comprehensive framework for managing MSD in the current system.To effectively support the MSP,the study concludes that the Act should provide a legal basis for securing implementation.Preparing standardized guidelines is essential to combine distributed marine space information into an integrated one.In addition,amending ambiguous clauses of the implementation of MSP is crucial. This research illustrates how the advanced framework of the MSD system can be applied to ROK in two ways:(1)by establishing an executive MSP organization to provide guidelines concerning MSD for related organizations,(2)by connecting administration such as licensing with this MSD system's scenarios.This advanced system shall increase not only the public's cyclical participation in the MSP processes utilizing open API but also public acceptability thereby improving the transparency of decision-making based on scientific data and shall decrease social conflicts on sea use.

12. A Study on Maritime Education and Training-Self-Evaluation,Mutual Evaluation and Multistep Evaluation-
摘要： Evaluation is an essential part of education and training,and it can be used in maritime education and training to help learners organize their knowledge and improve their skills,as well as to improve education and training methods.In this study,self-evaluation and mutual evaluation were conducted during anchoring training on the training ship Shioji Maru belonging to the Tokyo University of Marine Science and Technology.In a survey of students trained in 2020 and 2021 regarding the acquisition of knowledge and skills,94.2%of students rated themselves as"very effective"or"effective"in their self-evaluation and 92.0%of students rated themselves as"very effective"or"effective"in their mutual evaluation.Comparing the self-evaluation scores with the mutual evaluation scores,it was found that the mutual evaluation scores tended to rank higher than the self-evaluation scores.This is thought to be due to a lack of confidence in one's own ship handling skills,which leads to harsh evaluations of oneself and more lenient evaluations of others.It was also found that the higher the instructor's evaluation score,the smaller the difference between the self-evaluation score and the instructor's evaluation score.Students with higher scores in the instructor's evaluation were more confident in their ship handling skills,which is thought to indicate that they can evaluate themselves more accurately.On the other hand,self-evaluation was conducted at an early stage immediately after the training,and the bridge operation team and the entire team also conducted the self-evaluation again after the debriefing.In other words,a two-step evaluation was conducted through two evaluations conducted at different times.We show the results of a qualitative analysis of the students'impressions and opinions of this multistep evaluation using the steps for coding and theorization(SCAT)method.

14. A Study on Long Period Waves in Coastal Waters of Toyama and Niigata
摘要： The research on waves has been carried out in National Institute of Technology,Toyama College(NIT,Toyama College)since 1967,but generating mechanism of long period waves is not clear yet.And so,long period waves were investigated by analyzing tide levels which were observed at coasts of Toyama and Niigata in this study.The results are as follows. (1)There is a wave with period of about 321 days in residuals between observed and calculated tide levels,amplitude and phase of the wave in Toyama and Niigata are the same.The amplitude of the wave is 1.5cm and the phase of the wave is 284 degrees. (2)There is a wave with period of about 420 days in residuals between observed and calculated tide levels,amplitudes and phases of the wave in Toyama and Niigata are slightly different from each other.The amplitude of the wave is 1.3 cm in Toyama and 1.2 cm in Niigata and the phase of the wave is 263 degrees in Toyama,260 degrees in Niigata. The wave with period of about 321 days,amplitude of 1.5 cm and phase of 284 degrees,which exists in coastal waters of Toyama and Niigata,is generated by fluctuation of the earth gravity.Further there is a possibility that the wave with the period of about 420 days,which corresponds to chandler period(about 435 days),is driven by the polar motion.Moreover,the waves suggest that tectonic plates are swaying relatively to inner earth under asthenosphere,and as a result,gravity on earth surface fluctuations with periods of 321 days and 420 days. It is a future problem to make clear generating mechanisms of the long period waves.

15. Pressure Variation Model of an Underwater Vehicle through Multiple Motions using CFD simulation
摘要： An underwater vehicle operates efficiently in the water environment when it determines the speed and direction.In this article,we investigate the pressure variation model(PVM)of an underwater vehicle to predict its speed and direction.A series of pressure sensors located at the port and starboard sides along the submerged body is used to measure the variation of pressure surrounding the body.The dynamic pressure is a selection to consider as a function of the flow velocity acting on each pressure sensor.Due to the good accuracy and flexibility in motion simulation of the CFD(computational fluid dynamics)method,it is applied to execute the submerged vehicle motions from simple to complexes such as rectilinear,turning,gliding,and spiral motions.For each motion,motion variables including linear velocity,angular velocity,and angle are given to describe the trajectory as well as the characteristics of motions.Based on the results of pressure variation,pressure are big changed for the position the head and rear of AUV.The PVM is established considering the motion variables and positions of the pressure sensors.The PVM proposed is also used to determine the motion variables.

17. An Actively Positioning System with an Accurate Localization Technique for Sunken Container via a Three-layer Network Structure
摘要： Searching for the sunken container is a significant task when an accident happens.However,it is challenging to figure out the accurate position of the container in such a highly dynamic and complex ocean environment.The container must have passively waited for detection on the seabed via scanning technology,which is inefficient.To get rid of the situation,the paper proposes a three-layer network structure where the container equipped with the sensors can indirectly but actively indicate its location in the underwater layer and share it with users.Moreover,considering the acoustic signal stratification effect,a localization technique that combines the bisection method and a linear estimator is presented in the underwater layer.A theoretical analysis of the proposed technique is also conducted.Simulations demonstrate that the proposed method has a relatively satisfactory localization accuracy compared with other state-of-the-art approaches.

19. Identification of Noise Points in Buoy Telemetry Position Data Based on PSO-DBSCAN Algorithm
摘要： Buoys are artificial signs that guide the navigation of ships,and are of great significance to ensuring the safety of ships.The effective use of the buoy telemetry position data can analyze the offset characteristics of the buoy and improve the buoy's navigation aid efficiency.However,due to the influence of data transmission or human factors,the buoy telemetry data often contains noise points,which affects the application of buoy telemetry position data.To identify noise points in buoy telemetry position data,a DBSCAN algorithm optimized by particle swarm optimization is proposed,and the input parameters are determined adaptively to realize the identification of noise points in the buoy telemetry position data.Experiments on the relative buoy telemetry position data in Xiamen Port show that the PSO-DBSCAN algorithm can accurately identify the noise points in the buoy telemetry position data,and its effect is consistent with the actual situation.

33. The history of the training ship Kaiwo Maru and her achievements in promoting maritime affairs after retirement
摘要： Following the loss of the sail training ship Kirishima Maru at sea with all hands in 1927,two sail training ships,the Kaiwo Maru and her sister ship Nippon Maru,were constructed and launched in 1930.In the decades that followed,these sailing vessels provided apprentice seamen and officer cadets with safe and efficient deck training environments during numerous overseas voyages.During her 59 years of service prior to her retirement,Kaiwo Maru sailed more than 1,460,000 km and provided educational services to 7,708 trainees.After her retirement,she was moored at the Toyama Shinko Port in Imizu City,Toyama Prefecture,where she now hosts events such as full-sail exhibitions and other maritime educational programs.Through these efforts,the Kaiwo Maru increases visitors'knowledge and interest in ships and the sea while contributing to the maritime education of younger generations.This study was conducted as part of efforts to create a digital archive of the Kaiwo Maru's historic maritime heritage and to provide examples of the efficient usage of the accumulated data. Through our efforts,numerous ship documents related to the Kaiwo Maru's service as an active training ship,such as deck logbooks and illustrations showing construction and repair work,have been digitally preserved.Since these documents,which span the fields of navigation,shipbuilding,and maritime education,among others,are part of our nation's priceless maritime heritage,we began creating a digital archive by photographing various documents on display in the Captain's Office in place,starting with Logbook No.1,after which all 298 logbooks covering the period from 1930 to 1989,along with various documents since her retirement,were digitalized. Then,to explore the possibilities of various maritime education effects using the digitalized data,we conducted actual-finding investigations of the Kaiwo Maru's first journeys that we entitled"Maiden Oceangoing Voyage to Truk Island"and the"Challenging Voyage to the Bering Sea".

34. Collecting and Analyzing Successful Experiences in Difficult Collision Avoidance
摘要： A recently developed safety concept called Safety-Ⅱ has gained attraction to be implemented in a variety of disciplines.Safety II aims to ensure safety through flexible response and shows promising potential applications for the maritime domain.When considering effective safety training methods for nautical students and inexperienced navigation officers,it is necessary to develop new training methods based on the concepts of Safety II.This method of implementation needs to refer to the successful maneuvering experience of ship navigators.However,attaining meaningful maneuvering experience is difficult because the experiences like near-miss cases or minor accidents are not always reported in detail.In this study,we have determined the importance of learning from successful maneuvering experiences in difficult collision avoidance situations.Keeping these points in mind,this study aims to collect and analyze successful experiences in difficult collision avoidance.This study was successful in logging many different cases of successful collision avoidance.Results suggest that there is a difference between senior and junior navigators,and precautions,special training,etc.may be required in the ordinary practice of seafarers who face high cognitive demands in actual collision avoidance situations.Results also indicate that these precautionary techniques may require more than textbooks and classrooms to successfully train seafarers.The analysis carried out in this study clearly indicates that constructing a Safety-Ⅱ-based training method can enhance young navigator proficiency to adapt to safe ship-handling even in complex situations.

35. A Study on the Perception of Vessel Collision Risk of Trainees
摘要： According to the recent statistics of maritime accidents in Korea,collisions were the most common accidents related to maritime traffic.In IMO Model Course 7.03,which stipulated the training course to become an officer in charge of navigational watch,education on COLREGs72 takes up the most time.However,collision prevention education is insufficient in the training curriculum of Korea maritime educational institutions.Therefore,this study aims to suggest the need of collision prevention education for trainees by presenting the current status of Korea's on-board training and the trainees'perception of collision risk.To examine the trainees'perception of collision risk,a survey was executed on the trainees in training ships of the Korea Maritime and Ocean University at the 2nd semester of 2021.The valid responses of the survey were compared with the PARK(Potential Assessment Risk)Model,which is maritime traffic risk models of Korea.Analysis shows that as the boarding period has elapsed,the trainees felt a higher risk in encounters with other ships,and perception of collision risk among the trainees became similar.When comparing trainees and the PARK model,it was found that consigned trainees of 1st semester were most similar to the collision risk perception tendency of PARK model when they disembarked.This seems to be because,the consigned trainees spent a lot of time on the navigational watch on merchant ships during the 1st semester.However,the capacity of consignment training is restricted,so that the necessity for collision prevention education was magnified.Therefore,an AHP-based survey was conducted in order to derive the optimal collision prevention education method.As a result of the analysis,it was verified that simulation training is suitable for a collision prevention education.This study can be used as fundamental research for the development of collision prevention education using the simulator.

46. Revealing success factors of safe ship operations of experienced captains to assess functional requirements of Maritime Autonomous Surface Ships using FRAM
摘要： It is essential to reveal skills of experienced captains in order to define functional requirements of Maritime Autonomous surface ships(MASS).While textbooks,manuals,and laws define rules for captains and officers to follow,there are lots of other tacit knowledge,which are not written in documents,for safe ship operations.In this respect,it is essential to take into account complex dependencies among tasks/subtasks to build"an experienced captain's model".In order to accomplish this goal,we adopted a function-based modeling methodology which can support rich environmental factors for analyzing ship management operation.In this research,we conducted the following two steps to identify functional requirements of MASS,i.e.,1)modelling the skills of officers of the watch(OoW)from literature reviews,2)analyzing the actions of OoWs from the data acquired with gaze movements. Firstly,we performed modellings of OoWs'skills by utilizing FRAM.FRAM provides a way to describe how systems work in given working environment by using a characteristic functional representation of the systems as a diagram;each function of the systems is defined with six aspects,visually represented as a hexagon whose vertexes correspond to each of them,and eventually the systems are represented as a network of the six aspects.This representation provides complex dependencies among functions,and moreover,deeper insights about how the systems are successfully functioning.Secondly,we analyzed actions of OoWs observed in the simulator trial s,using data obtained from an eye-tracker,videos,and a wearable device to measure heart rate variability.Then we have examined relationships between the variety of the OoWs'actions and the heart rate variability.This study will contribute to define functional requirements of MASS for safety ship operations and assess the functions of MASS to develop.

摘要： In the airline industry,which handles the transportation as the maritime shipping industry does,the importance of non-technical skills as a required competency for airline pilots is recognized,and the education and training to enhance the ability such as situation awareness,decision making,and communication has begun.In the maritime shipping industry as well,Bridge Resource Management(referred to as BRM)competency was included in STCW from the Manila Amendments in 2010 for maintain a safe navigational watch,and it began to be required to educate and train the ability of situation awareness.It is necessary to enhance the ability of situation awareness of the officers in charge of a navigational watch(hereinafter,referred to as OICNW)to avoid collision with other ships. However,the current education and training for seafarers focused mainly on the requirements for obtaining a mariners license(STCW requirements such as basic knowledge for navigational skills,principles of navigational equipment,specific factors that affect ship maneuvering and so on.),which classified technical skills. In this study,in order to analyze the correlation between the situation awareness elements of OICNW's non-technical skills and the causes of ship collisions,authors created a situation awareness elements classification sheet on the navigational watch and analyzed which component is correlated to the collisions. In this paper,authors considered what kind of the education and training should be introduced to enhance the ability of situation awareness required for the OICNW in order to prevent the situation awareness category from leading to the collisions.
