International Organization for Standardization has recently published ISO 12215-5 which is the small craft-hull construction and scantling. According to ISO 12215-5 AnnexB, the scantling determination can be accomplished by drop test for craft with a length $L_H$ of 2.5m up to 6m and single-skin construction. The current method, however, of visual test has the issue where it is difficult to make an objective evaluation of ship body strength. In this study, in order to develop an evaluation system that can make a quantitative evaluation of the drop test of leisure boats, the domestic/foreign regulations on drop test of leisure boats are analyzed and the drop test evaluation system is designed, and the system applicability is reviewed through 5-meter level aluminum ship, and the issues incurred by the state of the ship and the posture while dropping were checked.

This paper describes a statistical analysis method for predicting a coast fishing boat's effective horsepower. The EHP estimation method for small coast fishing boats was developed, based on a statistical regression analysis of model test results in a circulating water channel. The statistical regression formula of a fishing boat's effective horsepower is determined from the regression analysis of the resistance test results for 15 actual coast fishing boats. This method was applied to the effective horsepower prediction of a G/T 4 ton class coast fishing boat. From the estimation of the effective horsepower using this regression formula and the experimental model test of the G/T 4 ton class coast fishing boat, the estimation accuracy was verified under 10 percent of the design speed. However, the effective horsepower prediction method for coast fishing boats using the regression formula will be used at the initial design and hull-form development stage.

Characteristics of restoring force for the wind-powered leisure boat was investigated using mathematical formulation and commercial computational method such as the ANSYS Workbench CFX-Mesh. The objective is to find the restoring moment and heel moment while boat is sailing in windy power. Conditions for angle of attack were given from $5^{\circ}$ to $90^{\circ}$. It is known that side force is larger in terms of angle of attack is higher, however critical angle is suggested to limit before over of $60^{\circ}$ for safe navigation for boat in wind. Natural results are found that stronger heel moment is observed when sail is used than no sail, and higher angle of attack is induced stronger heel moment.

During scuba diving in Korea, accidents involving bodies being struck by the ship propeller when entering and exiting the water, repeatedly occur every year. In response to the need to reduce accidents and implement safety management measures, Korea has established regulations for the installation and management of propeller guards. However, owing to the absence of clear production regulations in domestic laws and regulations, the installation standards are ambiguous, and the inspection items are limited to the appearance and fixation status. As a result, the safety of divers in propeller accidents is not guaranteed. Therefore, this study was conducted to specify the current legal requirements for the installation and inspection of propeller guards. To achieve this goal, we conducted a thorough analysis of the current state of domestic and foreign propeller guards and the legal factors pertaining to safety standards. Based on this analysis, we identified specific areas for improvement and proposed a plan to enhance the system for installation and inspection. The installation standards for propeller guards were clearly outlined in terms of the lattice size and material. Additionally, inspection standards were proposed for appearance, fixation, and material condition, along with clear indicators for assessing them.

The ancient fishing methods include stone fish weir, beach seine and baulk net, but the fish catches of the stone fish weir is the most abundant. The stone fish weirs not only constitute important landscape, but also are representative of the fishery culture in Penghu, because they are fishing ground built by ancient people to take advantage of natural environment and resources. The objectives of this study is to understand the relevance of stone fish weirs in Penghu and to preserve biological diversity, as well as the value of stone fish weirs in Penghu fishery culture, and further make suggestions on the stone fish weirs. According to the present study, the marine species around the stone fish weirs tend to be diversifying, and in the future the region's economy can be revitalized by sightseeing, which may promote the ecotourism, and also volunteer tourism. In the future, stone fish weirs must be promoted as a sightseeing destination. Also, by taking into consideration the experience of the Jibei stone weir protection team, the local communities of Penghu can have their own protection team to revitalize the stone fish weirs for sustainable operation and management.

The tourism industry is considered as the world largest industry and it is assessed as the most effective way to create employment. In particular, the marine tourism industry such as marine leisure sports, cruise can create high added value so that its significance has been more emphasized. Korea has natural tourist attractions such as more than 3,000 islands, about 12,000km lengths coastline, wide wetlands and beautiful seascape. In addition, the establishment of the five-day workweek and the development of means of transportation make the policy demand of the public for marine tourism increase continuously. However, Korea currently lacks policy and system for revitalizing marine tourism industry as the new growth engine and has not made good use of its retained tourist resource. Accordingly, this study explores the current situation and challenges of Korean marine tourism industry and further analyses the limits of the national legal systems for marine tourism. Lastly, it suggests policy recommendation for promoting marine tourism industry.

This study is to develop marine fashion items for various marine leisure activities based on the identity of Busan. Motifs from the fireworks festival and image colors of Busan are introduced for the items. A prototype design to express uniqueness and characteristics of fireworks was produced with a line combination among design modeling factors and applied to T-shirt item for comfort use in the marine leisure activity and daily life. T-shirt is one of fashion items for a message communication due to a unique modeling which can be used an excellent advertising item for the culturel identity and image of Busan. Designs were produced with the characteristics of fireworks in which circular shapes of a chrysanthemum, ring, and peony designates as motif 1, 2, 3 as well as linear shape of Niagara, fan shape, and tiger-tail as motif 4, 5, and 6. These designs were located on the front, central chest, and left chest in the T-shirts then analyzed by major students in the course of master and doctor of clothing and textiles with statistical methods. A design with new coloring preferred than the design of a symbolic construction, and circular design on the front and linear design on the left chest were preferred in the results. Prototypes were produced with peony and tiger-tail design which show a high corelation between circular and linear shape, and coloring as well as high purchasing needs. This study results will expect to use for the development of advertising items for the various events of Busan based on the textile design and fashion items with the identity of Busan.
