Abstract: 본 발명은 다음의 방법에 의하여 육가공품의 생산 공정에 있어서 육색 고정에 필요한 물질인 NaNO2(이하 아질산염)을 첨가하지 않고, 육색 고정 반응을 위한 원 물질인 일산화질소(이하 nitric monoxide)를 직접 이용하여 아질산염의 특징적인 육색 고정 작용과 같은 효과를 낼 수 있는 방법에 관한 것이다.  
     식육의 육색소인 myoglobin 단백질 내의 heme cell에 대한 육색 고정 과정은 현재 육가공 산업에서 주로 아질산염을 첨가함으로서 이루어지고 있다.  
     그러나 중요한 것은 육색 고정에 직접 필요한 물질은 아질산염이 미생물이나 낮은 산성의 환경에서 변화하는 과정을 거처, 발생되는 Nitirc monoxide에 의하여 육색이 고정되는 것이다. 이러한 것은 heme cell의 포피린 구조체의 6번재 연결 고리에 어떠한 기체가 반응되었는 가하는 중요한 부분이며, 이 6번째 고리에 nitric monoxide가 결합하며, myoglobin 단백질은 nitric oxide myoglobin이된다. 육가공 품은 이러한 nitric oxide myoglobin을 가열하여 육색을 고정하는 원리로 제품의 색상을 "발색" 시켜서 사용하는 것이다  
     또한 nitric monoxide는 물에 잘 녹지 않아 잔류량을 쉽게 제거할 수 있으며, 안정적인 기체로서 장기 보관이 가능하기 때문이다.  
     이러한 원리를 활용하여, 육제품의 육색 고정을 아질산염을 사용하지 않고, nitic monoxide를 직접 활용함으로서, 아질산염의 잔류량이 전혀 없거나, 획기적으로 줄일 수 있는 육제품 제조 공정에 활용할 수 있는 특징이 있다.

Abstract: A system and a method for mirroring a server are provided to mirror channel information generated from one server to another server by using a routing server having a relatively simple logic and enable a user connected to the server to monitor states of channels generated from another server. A message routing server generates publisher and subscriber groups(300,302), and makes the server participate in the publisher or subscriber group correspondingly to request information of the server. A publisher server(206) keeps connection with the message routing server by joining in the publisher group. Each mirroring server(202,204) keeps the connection with the message routing server by joining in the subscriber. If a channel is generated, the publisher server transmits a channel generation message and the message transmitted through the generated channel to the message routing server. If the channel generation message or the message transmitted to a publisher server channel is received from the publisher server, the message routing server transfers the received message to all mirroring servers joined in the subscriber group.
