  • As people have gained leisure time and become more interested in sports, various industries catering to these sports, including aquatic and underwater activities are growing. Many people are getting into scuba diving, where people can explore the sea at depths of more than 40-meters. Despite the increasing demand, there are limited studies on the sport. This study aims to provide basic research on materials suitable for developing technical scuba diving suits by analyzing several areas, such as design, material, sewing patterns, etc. The following trends were observed in all wetsuits: closure designs, ergonomic patterns, practical and functional details. Neoprene was the primary material of diving suits, and various functional materials were attached to the outer fabric or lining. The seam technique which minimized water contact and improved durability was sewing. Various techniques were also applied, such as flatlock stitching, GBS, LFS, etc. Subsequent studies shall investigate consumer preference etc. and other aspects, and continue to allow for the research and development of technical diving suits.

  • This study analyzed the recreational scuba diving regulations in Korea and other foreign countries and it proposes five changes to improve the Act On The Safety, Promotion, Etc. Of Underwater Leisure Activities in Korea. First, "recreational underwater activity participant" should be modified to refer to 'an individual or group of individuals entering into a contract with a recreational underwater activity businessperson for their own use'. Second, the person setting up the recreational underwater activity zone should be expanded to 'recreational underwater activity businessperson and/or recreational underwater activity participant'. Third, since recreational technical diving uses nitrox or mixed gas, a clause should be added that a sticker or band clearly indicating the type of gas should be attached. Fourth, a Surface Marker Buoy (SMB) should be added to the diving equipment, and the daily management and maintenance of cylinders should be specified in detail. Fifth, it is necessary to specify in the Act that recreational underwater activity participants are encouraged to purchase diving insurance for their own use. In addition, for the safety of underwater activity participants, the Act must specifically state the emergency procedures and diving guidelines of a recreational underwater activity businessperson.

  • This study suggests the improvement of ROK Navy salvage and rescue diving system. ROK Navy system experiences characteristic restrictions for the environmental loading. These restrictions are known to deteriorate the efficiency of Navy salvage and rescue diving activity. In this study, the measurements were suggested to improve the efficiency. To achieve the goal, a comprehensive analysis is conducted using the published data including those of USN, NOAA and IANTD. Based on the analysis, suggestions were made. The technical diving techniques may be introduced to improve current ROK Navy diving system in limited areas. By adopting that technique, decompression procedures and underwater operation can be improved.
