합성곱신경망(CNN)을 활용하여 국내 해양레저관광지 사진 분류 및 해양레저관광 행태를 분석할 수 있는가?

In order to quickly respond to changes in marine tourism trends and to establish effective policies, it is necessary to prepare a reliable method for collecting data on visits. The purpose of this study is to conduct an exploratory study on the behavior of marine leisure tourism users by using images, which are unstructured data of public data and social media data, in order to analyze the characteristics of domestic marine tourism. As a research method, the possibility was proposed as a new research method by using the convolutional neural network(CNN) algorithm used for image classification based on deep learning. Supervised learning was performed by classifying behaviors based on theories based on public data and images collected through SNS. As a result of the study, the behaviors of beach users were largely classified into landscape-based and activity-based. As the supervised learning of this study did not show satisfactory results, it is necessary to classify marine leisure tourism behavior by applying the photo classification algorithm for future research. In addition, a management plan for public data was proposed for continuous research use.

The purpose of this study is to analyze the problems of university yacht classes and suggest improvement using the delphi method measures to promote the future development direction of university yacht classes and further the qualitative and quantitative growth of marine leisure sports in universities. A group of experts involved in university yacht classes was selected as a population, and a total of 9 university yacht experts, university yacht administrators, and university yacht leaders were surveyed and studied using a purposeful sampling. Data processing analyzed the median, quartile, number of responses, and average for the degree of changeability and hope based on the linear formula, and the research results are as follows. First, the problems of university yacht classes were the lack of professional leaders, the lack of theory and practical skills, the qualty of classes decreased due to excessive staffing, the lack of post-class evaluation, the lack of equipment necessary for classes, and the lack of equipment storage facilities. Second, the improvement measures for the problems of university yacht classes were derived by training professional leaders, introducing self-directed education methods, organizing appropriate class personnel, applying systematic class programs step by step, supplying many equipment, and securing equipment storage facilities. Third, the possibility and degree of hope for the improvement of university yacht classes are highly likely to change and favor the degree of hope, such as securing a sense of safety and ethics, systematic post-evaluation after practice, centralized class due to weather problems, insurance registration and transfer of safety-related equipment.

Hydrodynamic Response Analysis of Hybrid Floating Structure according to Length of Damping Plate

New businesses such as marine leisure and floating construction have recently flourished on the coast. As a result, consideration is given to a floating structure appropriate for marine environments. In this study, we applied a damping plate to increase the stability of a hybrid floating structure that was expanded by vertical and horizontal stacking of mobile unit modules. In the numerical analysis using ANSYS AQWA, the behavioral characteristics of the floating structure were analyzed according to the length change of the damping plate. However, the wave forces acting on a floating structure are excessively calculated by the resonance of fluid surrounded by the structure in the numerical analysis using potential flow. Therefore, we used the damping zone option of the ANSYS AQWA in the frequency domain analysis.

Insights into coral restoration projects in Japan

Coral transplantation, including out-plantation, is performed worldwide to restore coral reefs. To date, >300 000 coral colonies have been transplanted in Japan, and the survival rate of transplanted corals is mostly <20% after 4 years. Here, I highlight problems that have arisen as a result of coral restoration projects in Japan and discuss solutions that may maximise transplantation effectiveness. The government, companies, and researchers have focused on the positive aspects of transplantation technology and new biological findings; however, negative aspects such as the high mortality rate for transplanted corals and high maintenance costs have garnered less attention. Uncritical and incomplete coverage of reef projects by the mass media has led to a misconception that the coral reef crisis can be resolved by current biological engineering solutions. Therefore, transplantation has been used to justify sea reclamation including marine leisure facilities and various other construction projects. Consequently, approximately 400 ha of coral reefs in Japan have been lost in only a decade. Understanding the limitations of transplantation techniques is necessary, and hence, I propose that coral transplantation guidelines be adopted to prevent further loss. Further advances in transplantation technology are required to increase scalability and cost-effectiveness and improve survival/performance; however, practitioners, researchers, companies, and governments, especially in environmentally unconscious countries, should clearly state that coral transplantation cannot restore large-scale coral reef ecosystems and should not be used to justify land reclamation affecting reefs, as mentioned in most international guidelines. Moreover, when coral transplantation and seedling production are used for environmental education, the death of transplanted corals and difficulties underlying artificial coral regeneration should be clearly explained. Effective coral transplantation use within a conservation framework is critical to avoid high and unfounded expectations.

선박 주취운항 관련 법령의 개정방안 연구

The majority of trade in Korea is centered on international trade rather than local demand. Because of the topographical features of the sea on its three sides, most of the trade is carried out by sea transport. In recent years, there has been an increase in marine accidents due to the growth of the marine leisure industry, offshore fishing, and deep-sea fishing. Given that property damage and mortality are significantly higher in maritime drunk accidents than in land-based ones, it is thought that drastic remedies are required. It takes the shape of a single legal system centered on the Road Traffic Act when it comes to drunk driving, independent of the use of the vehicle, the area, the size of the driving, etc. In the case of marine drunk driving, depending on the purpose of use of the vessel, the location of the operation, and the size of the vessel, the Marine Safety Act, the Water Leisure Safety Act, the Cuise ship and Ferry Business Act, and the Fishing Management and Raising Act are applicable. The lack of uniformity in the marine drunk driving requirements, the authority for punishment and enforcement, etc., is an issue as a result. In this way, it seems necessary to solve the problem in that it goes against the principle of proportionality or appropriateness in the effectiveness and punishment of enforcement, because the punishment is different or the enforcement authority is limited despite the same drunken operation depending on the location, size of the vessel, and the purpose of use of the vessel. Therefore, the related regulations for drunken operation are considered and the purpose is to solve the problems in this paper. Consequently, it is intended to solve the problem of coherence related to drunken operation and derive a unified revision to prevent accidents of drunken operation and to provide equitable punishment by allowing the contents of each law to be unified and by deriving the consistency of each related law which the actual condition of drunken operation is reviewed, and the standards, prohibitions and penalties for drunken operation related to the current drunken operation are considered through each law in this paper.

여가활용의 방안으로 레저스포츠 참여와 생활체육 활용의 이원적 고찰

Today, as Korea grows remarkably economically, the quality of life of the people is improved, and it is also developed into a five-day workweek, and furthermore, into leisure culture. In particular, as the number of participants in leisure sports increases due to the natural environment surrounded by the sea on three sides, marine leisure sports are in the spotlight due to the good use of leisure activities. On the other hand, the state and local governments are legally encouraged and participation in sports for all is encouraged by the good use of leisure time that falls short of the area of leisure sports that requires some economic (leisure organization) and expertise (navigation). In this sense, this paper aims to promote national leisure activities and contribute to the creation of leisure culture by presenting a model that induces the participation of leisure sports as a professional leisure activity and promotes the use of sports for the good use of leisure by the general public.

해양레저체험과 재미인식, 삶의 질의 구조적 관계

Modern people have increased their interest in various physical activities due to their desire for a healthy life, and their values have started to change towards the pursuit of leisure forms that accompany active physical activity. In the tourism field, various leisure sports activities are changing to a dynamic form, and the psychological state of the experience is a major research subject in the tourism field. It is reported that leisure and leisure activities contribute significantly to the quality of life by helping to change mood, relieving stress, enhancing self-confidence, and self-satisfaction. Therefore, it is possible to infer that the marine leisure experience can be a psychological channel that induces the quality of life through fun recognition. In recent studies, there are few cases of research on the relationship between marine leisure experience, fun perception, and quality of life of skin scuba divers. In particular, it is difficult to find studies that verified the structural relationship of quality of life through marine leisure experiences through empirical studies. Therefore, the purpose of this study is to establish and explore the structural relationship that improves the quality of life of skin scuba divers through marine leisure experiences. 209 copies of research results using analysis data, the marine leisure experience was found to have a positive (+) effect on the perception of fun and the quality of life.

해상상태별 낚시어선 안전조업 합리화 방안

Sea fishing has established itself as a popular means of marine leisure activity for the whole nation, with people’s increasing earnings, achievement of marine leisure culture and increasing interests in the ocean. The number of fishing vessels users reached about 4.8 million in 2019, and constantly increasing. However rise in marine accident of fishing vessels has caused escalating anxiety about fishing vessels and distrust of safety policies. Collision and stranding were the highest in the number of occurrences and casualties among marine accidents of fishing vessels. when analyzing the sea state in the accident of fishing vessels collision and stranding, weather factors such as regional occurring fog are the acting as the cause. The sea fog’s occurring areas and routes are various depending on the elements such as the sea area and season. When the sea fog occurs, marine accidents of fishing vessels can be possible to prevent by alerting ever-changing fog information to captain of fishing vessels, which is quickly and accurately collected and analyzed.&#x0D; Safe fishing, considering sea state, will be able to carried out by establishing “Control Regulation for Satety Fishing” for fishing vessels based on maritime weather information.

Simulation of Marine Leisure Accidents Using Random-Walk Particle Tracking on Macro-Tidal Environment

In the west coast of Korea (WCK), macro-tidal environments with wide tidal flats yield distinctive characteristics such as recursive tidal currents and tidal asymmetry. Here, we proposed an efficient search and rescue (SAR) computation method for WCK conditions (where bottom shapes affect nearshore sticking) using a finely resolved wet–dry circulation model. A random-walk particle tracking module (PTM) was applied to an unstructured finite element model to provide the SAR information needed to mitigate the consequences of marine leisure accidents. To capture the unique external forcing characteristics affecting the nearshore SAR case, sensitivity tests, which considered the characteristics of human bodies in particle representation, were performed on an idealized basin under typical external forcing. Furthermore, the effects of surface drag were included to represent real conditions more accurately. Our simulations showed that the accuracy of initial accident times for in situ mannequin floating tests (where several initial locations and times of accidents were used) directly affected the accuracy and effectiveness of SAR missions. However, to understand and predict the missing floating person in real time, additional intensive field experiments are required that account for the local geomorphological characteristics, external real-time temporal tides, and wind forcing incorporating extreme weather conditions.

FFF 3D 프린터를 이용한 DfAM 기반 소형선박용 스탠션 지속가능 개발 사례 연구

In this study, the 3D printing technique called design for additive manufacturing (DfAM) that is widely used in various industries was applied to marine leisure ships of equipment. The DfAM for the stanchion for crew safety was applied to the equipment used in an actual recreational craft. As design constraints, the design alternatives were not to exceed the safety and weight of the existing stainless steel material, which were reviewed, and the production of a low-cost FFF-type 3D printing method that can be used even in small shipyards was considered. Until now, additive manufacturing has been used for manufacturing only prototypes owing to its limitations of high manufacturing cost and low strength; however, in this study, it was applied to the mass production process to replace existing products. Thus, a design was developed with low manufacturing cost, adequate performance maintenance, and increased design freedom, and the optimal design was derived via structural analysis comparisons for each design alternative. In addition, a life-cycle assessment based on the ISO 1404X was conducted to develop sustainable products. Through this study, the effectiveness of additive manufacturing was examined for future applications in the shipbuilding industry.

Proposal for the Expansion of Research on the South Korean Marina Development Project

Kim, J.-S. and Jang, S.-H., 2021. Proposal for the expansion of research on the South Korean Marina Development Project. In: Lee, J.L.; Suh, K.-S.; Lee, B.; Shin, S., and Lee, J. (eds.), Crisis and Integrated Management for Coastal and Marine Safety. Journal of Coastal Research, Special Issue No. 114, pp. 345–349. Coconut Creek (Florida), ISSN 0749-0208. The South Korean Marina Development Project includes a long-term plan to construct an industrial cluster and a marina business model by developing marinas nationwide since 2010. This plan aims to develop coastal/fishing regions across the country into leisure hotspots. Building on active support from the government, this led to the establishment of the Second Marina Basic Plan in 2020, making this the largest marine leisure project in the country to date. Unfortunately, many marinas across the country face severe difficulties owing to various causes. In this study, we aimed to suggest new directions for research on the Marina Development Project as part of a series of academic efforts to resolve problems with the project. To this end, we conducted a literature review to explore (1) the current project and the directions of previous research by inspecting “the current state of the Marina Development Project and related research trends” and (2) “the expansion of research on the Marina Development Project.” More specifically, we claim that there is a need for “critical research examining the nature of the problems that have caused failure to date” and for a “cultural approach to participants.” Finally, we also emphasize the need for “community governance research” as a practical and long-term solution. This expansion of research can guide recovery from the various difficulties faced by the current Korean Marina Development Project.
