Disclosed is a method of preparing a knitting yarn having a water-repellent function, including providing a knitting yarn in the form of a skein or a cone, washing the provided yarn to remove impurities and oil therefrom, coating the washed yarn with a water-repellent agent by spraying a water repellent solution containing the water-repellent agent at a predetermined pressure, dehydrating and drying the coated yarn, and fixing the water-repellent agent to the yarn by applying heat to the dried yarn.
摘要:
The present invention relates to a method for preparing clopidogrel 1,5-naphthalenedisulfonate or a hydrate thereof, which comprises reacting a clopidogrel-acid addition salt with disodium 1,5-naphthalenedisulfonate or its hydrate in water, or a mixture of water and an organic solvent. High quality clopidogrel 1,5-naphthalenedisulfonate can be prepared by the inventive method by way of using non-corrosive disodium 1,5-naphthalenedisulfonate.

Ticlopidine and clopidogrel having high blood platelet aggregation inhibitory and anti-thrombotic activities are simply prepared by reacting a substituted thiophene derivative with a 2-chlorobenzylamine derivative.
摘要:
Optically pure clopidogrel can be prepared in a high yield by optically resolving a racemic form of the compound of formula (II) using an optically active amine to form the optically active form of the compound of formula (III) or its acid-addition salt; and methylating the compound of formula (III) or its acid-addition salt.
摘要:
It is possible to filter spam of diversified Internet protocol (IP) multimedia applications, since it is possible to provide spam filtering services suitable for various processing methods of calls of the IP multimedia applications and media features in an application server layer without changing a structure of IP multimedia service network by classifying calls of IP multimedia application services based on service features, checking policy information of the calls classified based on the service features, filtering spam so as to determine whether the call is spam through dynamic filtering mechanism for each application service, and transmitting the call to a lower network by determining a suitable processing method based on the checking result of the policy information or the filtering result, so as to filter IP multimedia spam in an application server in a network for providing various real-time IP multimedia application services.

摘要:
Provided is a method and apparatus for configuring and managing an overlay multicast data delivery tree in a transmission network having a SM (session manager) and at least one MA (multicast agent). The method includes the steps of at the MA intending to joining a session, obtaining an active neighbor MA list from the SM; detecting information on QoS information of each neighbor MA in the active neighbor MA list, selecting a MA having the most optimized QoS as a parent MA based on the QoS information of each Neighbor MA in the active neighbor MA list, joining an overlay multicast data communication session through the selected parent MA, periodically receiving HB (heart beat) information having information on a path from a root to the MA and determining whether to perform a parent-switching based on me HB information and parent-switching from the current parent MA to a MA having a better QoS when it is determined to perform the parent-switching
