    摘要: An apparatus and method for delay time computation and delay compensation between a Base Station (BS) and a remote Radio Frequency (RF) unit in a broadband wireless access system are provided. In a method of operating an apparatus for determining a delay time to compensate for delay between a BS modem card and a remote RF unit in a wireless access system, the method includes determining a process delay time required when traffic data is output from the BS modem card to an antenna of the remote RF unit in a state where a reference cable having a length short enough to neglect a cable delay time is connected between the BS modem card and the remote RF unit, determining a cable delay time required when a sync pulse signal is transmitted through a cable used in actual system operation between the BS modem card and the remote RF unit, and determining a time for outputting traffic data at an earlier time from a modem included in the BS modem card by using the determined process delay time and cable delay time.

    摘要: The present invention relates to covered porous biodegradable polymer microspheres for sustained-release drug delivery and tissue regeneration which has an interconnected inner open pore structure having a wide surface area and high porosity and an outer closed pore structure in which the surface of the microsphere is covered with a thin layer of a biodegradable polymer, and thereby the pores formed on the surface and exposed to the outside are closed; and methods for preparing the same. Due to such a characteristic pore structure, the covered porous biodegradable polymer microspheres according to the present invention can prevent the biologically active material from being excessively released in the early stage immediately after administration, and after that, can gradually release the biologically active material through the interconnected inner pore structure over a prolonged period as the biodegradable polymer thin layer is degraded. Therefore, the microsphere of the present invention can be effectively used for sustained-release drug delivery and tissue regeneration.
