This study focused on the movement adaptability of 19th century classical opera stage costumes. Researchers focused on a basic 19th century women’s jacket. The study analyzed movement adaptability using ROM (range-of-motion) tests of the upper limb flexion and abduction postures. It developed two research garments to mimic basic 19th century style jackets with or without gussets at the axilla. The ROM experiment identified the gusset size as 11cm in length. Experimental postures included upper limb flexion and abduction. The study measured subjective comfort at 8 postures. These postures included the flexion and abduction of the arms and torso. Subjects also evaluated the subjective comfort of the rotation posture of the torso. Researchers evaluated the similarities between research garments’ silhouettes and the 19th century women’s jacket. The study used a 3D virtual fitting system to evaluate fit, and specialists further analyzed fit with photographs and 3D virtual graphics. The results are as follows. The silhouettes of both research garments were similar to the silhouettes of the 19th century western women’s jacket. The jacket with axilla gusset had a better fit than the basic style jacket. The basic style jacket without the axilla gusset showed limited movement adaptability at the shoulder joint and it caused discomfort at the axilla and elbow. The 3D virtual fit test was not a suitable method for analyzing silhouette similarity.

The Digital Right Management is a technological measure that is used to protect the digital contents from illegal infringements without proper permissions. The fundamental license of DRM belongs to InterTrust and patent issue remains. There are two legal issues of DRM Technology. At first it’s DRM protection. Although the technological protection measures are becoming highly sophisticated, all the measures could be eventually defeated by technologically sophisticated users. So WIPO treaty, DMCA, EU directive and korean copyright act protect the technological measures. French copy right act accepts the content of EU directive. Second is DRM standard. Standardization of DRM is not established. Many groups like Microsoft, Apple and OMA compete to obtain DRM technology standard. At present the problem of interoperability among different DRMs is not solved. SK telecom accepts EXIM developed by MIC and ETRI and is scheduled to make interoperability possible.
