Recently, people's interest in marine leisure has been increasing, and research and development on leisure boats are actively being carried out to pioneer overseas markets. These days, the materials used for leisure boats are fiber-reinforced plastic (FRP) and aluminum alloy. However, FRP is hygroscopic and causes environmental problems, and aluminum alloy has high thermal conductivity and fire susceptibility. Therefore, titanium alloy is being adopted as a material for leisure boats instead. In this study, hull thicknesses and design pressures were calculated while considering dynamic effects for titanium boats. Four sets of rules and regulations were used: ISO 12215-5, RINA Pleasure Yacht, LR Special Service Craft, and KR High-speed Light Craft. The maximum bottom slamming loads were in the order of ISO, KR, LR, and RINA, and the required hull thicknesses were in the same order. This research might be helpful for understanding the rules, regulations, and overseas export of leisure boats.

전기차 충전 장치가 전기차로부터 ISO/IEC 15118 국제 표준을 따르는 XML 형식의 통신 메시지를 받아 IEC 61850 국제 표준의 SCL (Substation Configuration Language)로 구성되는 논리 노드를 통해 통신 메시지를 전력 계통으로 보낸다. 역방향 통신 메시지의 경우에는 그 역순으로 진행된다. ISO/IEC 15118 국제 표준이 XML 형식을 스키마로 규정하고 있고 IEC 61850 국제 표준이 SCL 형식을 스키마로 규정하고 있으며 두 스키마를 변환하여 ISO/IEC 15118 통신 메시지와 IEC 61850 통신 메시지를 상호 변환할 수 있다.
