본 논문에서는 광역의료서비스인 항공응급의료체계에서 요구되는 심전도, 혈압등과 같은 의료신호를 저장하기 위해 표준방식인 부호화기를 구현하기 위한 파서를 설계한다. 부호화기는 MDER에 기초하여 테그에 의해 파형의 정보를 부호화하고 이를 저장하기 위한 방법으로서, 이를 구현하기 위해서는 각 테그의 적용 범위를 고려하여 부호화기의 파서 구조를 설계하여야 한다. 연구에서는 테그간의 영향을 미치는 범위를 고려하여 루트속성을 갖도록 한 부호화기 파서의 구조를 설계한다. 설계된 파서는 구현을 통해 다른 구조들과 비교한다.

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.
