  • The grinding process is very complex and relates many parameters to control the process. As this reason, a theoretical analysis and a quantitative estimation of the grinding process has not been well established. In this study, the in-process monitoring system was suggested by applying the neural network for monitoring and shooting the malfunction of cylindrical plunge grinding process. This system used the power signals from the electric power meter. This neural network was composed of processing elements [4-(5-5)-3] with 4 identified power parameters. Because sensitivity is blunted some minute vibration components, the simulation result of this system has appeared about 10% erroneous recognition in the uncertain pattern and the average success rate of the trouble recognition was about 90%. Consequently, the developed system, which applied to the power signals, can be recognize enough to monitor the grinding process as in-process.

  • Recently, Trouble of sand supply is occurred according to exhaustion of natural sand resources. therefore, various measures are proposed for solution of trouble of sand supply and crushed sand among measures is used as one of most universal measures. but crushed sand which have poor particle shape and plenty of makes micro particle the qualify of concrete deteriorated. Therefore, this study evaluated physical properties of mortar using crushed sand and applied evaluation result to fundamental data The result of this study have shown that quality of mortar using crushed sand independently is poor against general mortar. but, mortar flow and compressive strength is increased in case of using crushed sand according to mixing ratio properly.

  • 현재 통신망상에서 운영되고 있는 네트워크 장애처리시스템의 가장 큰 문제점은 통신망상에서 발생한 장애를 보고하는 기능은 지니고 있지만, 이에 대한 효율적 처리의 방안이 부족하다는 것이다. 또한 발생한 장애에 대한 데이터베이스 유지와 이를 활용하여 지식 정보화를 구축하는 측면과 통신망 사용자의 문의 및 불만 상담을 처리하고, 사용자에게 장애 처리에 대한 정보를 제공하는 기능은 거의 제공되고 있지 못하다. 이러한 통신망 상에서 발생하는 장애를 효과적으로 해결하기 위해서는 장애를 처리하는 네트워크 장애처리시스템(Network Trouble Management System)이 필수적으로 요구되며, 이에 대한 운영 방식을 효율적으로 개선함으로써 통신망 장애로 인한 시간적, 경제적 손실을 최소화하고, 사용자와 관리자 모두에게 효과적인 시스템에 대한 구축의 필요성이 증대하고 있다. 본 논문에서는 전문가 기반의 장애처리시스템에 자동 응답 시스템을 접목시켜 각 분야의 전문가들을 영입하고 관리할 수 있으며, 기존의 장애 처리 데이터베이스를 활용하여 사용자에게 장애처리에 대한 방안을 제시한 수 있는 전문가 기반의 확장 장애처리시스템을 구현함으로써 사용자에게 신뢰성 있는 고부가가치의 서비스를 제공할 수 있게 하였다.

  • Objective : I would define the differences of sentences that 'A tongue can detect five basic tastes' and 'A mouth can perceive the five cereals' in Youngchu Macdo(靈樞 脈度). Methods : 1. I refer to literatures for the sentences in Youngchu Macdo 2. I look into the symptoms which may be caused by heart and pancreas troubles, respectively. Result : Human being can not detect a specific taste on his heart trouble. That is, acid, bitter, sweet, hot, and saltness can be all one. Human being may lose his appetite on his pancreas trouble. Even though the viscera and the tongue are connected to on-meridians, the function of a tongue is managed and controlled by a heart. Such a tongue perceives five basic tastes. Conclusion : A healthy tongue appreciates five basic tastes clearly and a healthy mouth may stimulate his appetite.

  • Undesired trouble such as chatter vibration and burning on the ground surface appears frequently in the cylindrical plunge grinding process. Establishment of a credible fault diagnostic system for the grinding process is the major purpose of this study. Power signals generated during the grinding operation were sampled and analyzed to determine the relationship between grinding troubles and behavior of signal changes. In addition, a neural network was optimized with a momentum coefficient a learning rate, and a structure of the hidden layer through the iterative learning process. Based on the established system, success rates of the trouble recognition were verified.
