In this paper, we propose the parser structure to realize the encoder which is standardized encoding rules to code and store the medical waveform such as an electrocardiogram or an blood pressure in aviation emergency medical service. To design the encoder based on the MDER, the effect on the scope of each tag should be considered. we design the parser with the root property which is to clarify the effect of scope between tags. the presented parser is implemented and compared with the other structures.

The capsizing and consequent sinking of a coastal car ferry was recently reported, with numerous human casualties. The primary cause was determined to be a sudden turn with improperly stowed and secured cargo. Part I of this study introduces how long term acceleration components are determined from seakeeping analyses. A carferry with a displacement of 1,633 tonf was selected as the target vessel. Sea data that included the significant wave heights and periods were collected at four observation buoys, some of which were far away from two main voyage routes: Incheon-Jeju and Pusan-Jeju. Frequency response analyses were performed to obtain the linearized radiation force coefficients, hydrostatic stiffnesses, and wave excitation forces. Time response analyses were sequentially performed to produce the motion-induced acceleration processes. The probabilistic distributions of the acceleration components were determined using a peak and valley counting method. Long term extreme acceleration components were proposed as a final result.
