Augmented Scale은 모던한 사운드의 스케일로서 현대 재즈에서 종종 사용되고 있다. 본 연구에서는 재즈 피아니스트 비안(Vian)의 작품 "Wilderness"에서 이 스케일을 멜로디와 화성에 어떻게 적용했는지 살펴본다. 무엇보다도 이 곡의 솔로 형식(solo form)에서 즉흥연주(improvisation)를 위한 재즈 라인 (jazz line)을 어떻게 접근할 것인지 연구한다.

EPONs are a low cost, high speed solution to the bottleneck problem of broadband access networks. To support point-to-point and shared LAN emulation, EPONs use the multi-point control protocol (MPCP), which uses logical link identification (LLID) for frame tagging and filtering between the OLT and ONUs. In this paper, ONU-based multicast or multiple shared LAN emulation is used for IPTV channel package delivery services. Using ONU-based VLAN services, EPONs can support separate and secure connections between providers and subscribers in a simple manner. Also, IPTV channel packages can be delivered through EPONs by implementing ONU-based VLAN and IGMP snooping mechanisms. By showing fast channel zapping time of proposed architecture, I show that EPONs is suitable for IPTV channel package delivery service.
