This study aimed to investigate the formation of the social perception of domestic maritime sports using text mining analysis of keywords and topics from domestic media coverage over the past 10 years related to representative maritime sports, including yachting, rowing, and canoeing. The results are as follows: First, term frequency (TF) and word cloud analyses identified the top keywords: "maritime," "competition," "experience," "tourism," "world," "yachting," "canoeing," "leisure," and "participation." Second, semantic network analysis revealed that yachting was correlated with terms like "maritime," "industry," "competition," "leisure," "tourism," "boat," "facilities," and "business"; rowing with terms like "competition" and "Chungju"; and canoeing with terms like "maritime," "competition," "experience," "leisure," and "tourism." Third, topic modeling analysis indicated that yachting, rowing, and canoeing are perceived as elite sports and maritime leisure sports. However, the perception of these sports has been demonstrated to have little impact on society, public opinion, and social transformation. In summary, when considering these results comprehensively, it can be concluded that yachting and canoeing have gradually shifted from being perceived as elite sports to essential elements of the maritime leisure industry. Contrariwise, rowing remains primarily associated with elite sports, and its popularization as a maritime leisure sport appears limited at this time.

The 6m class high speed boat is developed with a durable hull and inflatable tube, which is called RIB(Rigid Inflatable Boat), for the purpose of marine leisure. In the stage of the conceptual design, its requirements to be optimized are determined based on the presented information of similar marine leisure RIBs. The 3-D graphical technique using Marine Rhino is utilized to optimize the compartment layout of RIB. The stability analysis is performed for the light and full load conditions with and without the inflatable tube. In addition, the sea keeping and hydrodynamic performance was tested using the proto-type ship in the sea condition. From the results of the computation and the sea trial test, it shows that the performance of the marine leisure RIB satisfies the speed, the convenience, and the stability requirements. This study provides the typical information of the design factors and the procedure to manufacture the marine leisure RIB.

In this world, the interest in the marine leisure-sports, nature friendly oriented, has been increased. The width of leisure activities has became enlarged because of expansion of leisure time and the changes of recognition on the rational management and use of marine resources. Marina ports influence significantly marine leports and this paper reviewed the maria ports status and problems. This Country has strived to develop marina ports in local areas, designing the 1st basic National Plan of Marina Development. We have keen interest in Marina but have no detail strategy and preparation. This paper suggested how marina port shall be developed for the expansion of marine leports and what strategies shall be adopted for the activation of the facilities. After reviewing the previous researches and with the results of questionnaire survey, this paper suggested two types strategies. First on the policy oriented point, it suggested 10 alternatives on the perspectives of development and operation areas. Secondly, it proposed some strategies for the activation of marina ports on the aspects of 4Ps of marketing. This paper theoretically groped the activation schemes with the knowledge and experiences of experts, but it is recommended furthermore some survey on the practical field and user attitude must be progressed.

Cisplatin has been reported to cause side effects such as muscle wasting in humans and rodents. The physiological mechanisms involved in preventing muscle wasting, such as the regulation of AKT, PGC1-α, and autophagy-related factor FOXO3a by MuRF 1 and Atrogin-1, remain unclear following different types of exercise and in various skeletal muscle types. Eight-week-old male Wistar rats (n = 34) were assigned to one of four groups: control (CON, n = 6), cisplatin injection (1 mg/kg) without exercise (CC, n = 8), cisplatin (1 mg/kg) + resistance exercise (CRE, n = 9) group, and cisplatin (1 mg/kg) + aerobic exercise (CAE, n = 11). The CRE group performed progressive ladder exercise (starting with 10% of body weight on a 1-m ladder with 2-cm-interval grids, at 85°) for 8 weeks. The CAE group exercised by treadmill running (20 m/min for 60 min daily, 4 times/week) for 8 weeks. Compared with the CC group, the levels of the autophagy-related factors BNIP3, Beclin 1, LC3-II/I ratio, p62, and FOXO3a in the gastrocnemius and soleus muscles were significantly decreased in the CRE and CAE groups. The CRE and CAE groups further showed significantly decreased MuRF 1 and Atrogin-1 levels and increased phosphorylation of AKT, FOXO3a, and PGC1-α. These results suggest that both ladder and aerobic exercise directly affected muscle wasting by modulating the AKT/PGC1-α/FOXO3a signaling pathways regardless of the skeletal muscle type.

This study attempted to categorize the motivation for participation in leisure sports and analyze the difference in consumer demand for leisure sports wear according to the type. As a result of the analysis, the functionality of the preferred material consisted of movement, comfort, and body temperature maintenance. When purchasing, the factors to consider were extracted such as basic emphasis, emphasis on flaunting, and emphasis on practicality. The improvement requirement was composed of basic function improvement and various function additional factors, and the purchase satisfaction factor was composed of three factors: brand, practicality, design, and functionality. Motives for participation in marine leisure sports were grouped into mania, leisure, and health types. As for the functionality of the preferred material, the mania type and leisure type preferred movement, comfort, and body temperature maintenance functionality over the health type. As for the factors to consider when purchasing, the mania type and leisure type had higher consideration for the factors of basic emphasis, ostentation, and practicality than the health type. In the improvement requirements, both basic function improvement and various function additions had the highest mania type and the lowest health type. In terms of purchase satisfaction factors, practicality and brand were found to have a high leisure type, and functional factors were found to have a high mania type. For the enthusiastic group, it is thought that product development should focus on functionality and additional functions, and health types should be focused on design and utilization.
