MPEG그룹은 미디어 객체를 시간과 3차원 공간상에 배치하여, 멀티미디어 컨텐츠를 표현하고, 사용자의 상호작용을 가능하게 하는 MPEG-4 System을 표준화하였으며, 다양한 전송계층 (File, TCP/IP, Broadcasting등)을 통합하여 처리할 수 있는 DMIF (Delivery Multimedia Interface Framework)[3] 전송규약을 표준화하였다. 이 논문에서는 MPEG-4 System의 BIFS와 SCENE을 제작할 수 있는 저작툴의 설계와 구현을 함으로써 MPEG-4 System을 이용하여 비디오, 오디오, 그래픽과 같은 다양한 미디어들을 결합해주고 사용자와의 상호작용에 의한 실시간 표현을 가능하게 해주며 사용자가 MPEG-4 System에 대해서 잘 알고 있지 않더라도 손쉽게 MPEG-4 미디어 파일을 만들 수 있도록 해주는 저작툴을 제안한다[1,3,5].

We reviewed the Magnetic Resonance Imagings(MRI) of 41 knees in 41 patients who had confirmed discoid lateral menisci of the knee joint arthroscopically from Nov. 1991 to Jan. 1994. The purpose of this study is to demonstrate the diagnostic value of MR imagings for discoid lateral meniscus and to describe the characteristic findings of MR imagings according the type of tears and to explain the causes of mis-diagnosis. Type of tears were confirmed by either arthroscopic finding or gross specimen. Peripheral detachment were found in 13 discoid menisci(31.8 %), complex tears in 16(39.0 %), horizontal tears in 5(l2.2%), longitudinal tears in 4(9.8%), transverse tears in 2(4.8 %) and intact in 1(2.4 %) discoid meniscus. 36 out of 41 discoid lateral menisci(87.7%) were correctly diagnosed as discoid menisci preoperatively on MR imaging. However 5 were mis-diagnosed as lateral meniscal tear. It was very difficult to diagnose discoid lateral meniscus which had detached from meniscosynovial junction and displaced into the center or had transverse tear in mid-horn. We also found that MR imagings showed the correct torn shape of 27 out of 36(75 %) discoid lateral nenisci which were correetly diagnosed as discoid menisci. Accuracy of MR imagings for each type of tear were follwings : 50 % for horizon, 100 % for peripheral tear, 73.3 % for complex tear 33.3 % for longitudinal tear, 0% for tranverse tear. On the MR imaging, capsular attachments of the popliteal muscle in knees with discoid meniscl were compared to those of 100 knees with normal lateral menisci. Capaular attachments of popliteal muscles were divided to three : type 1 is fibrous band, type 2 is thin muscle bundle, type 3 is thick muscle bundle. Capsular attaehments of popliteus muscle in the knees with discoid meniaci(68.3 %) had significantly higher incidienee of type 2 or 3 compare to the knees with normal lateral meniacus(32 %). As conclusion, MR imagings for diagnosing of discoid lateral meniscus had a relatively accurete diagnotic value and also shoed the its type of tear. It is very important to realize type of dicoid meniscal tear in order to obtain correct diagnosis.
