        IP 기반의 다채널 엘리베이터 영상감시 시스템

        신재흥(Jea-Hung Shin),김홍열(Hong-Ryul Kim) 대한전기학회 2013 전기학회논문지 P Vol.62 No.4

        Recently, in the elevator of the buildings, such as apartment and office building, the visitor monitoring cameras for surveillance, advertising LCD to provide a variety of information , emergency call devices, and safe driving information sensors are installed. A variety of multimedia data from these devices to the central control office, management office, or to guard room are transmitted in real-time. Each sub-systems in the elevator are installed with a separate lines and operated independently and use different management principals, so integrated management for each sub-systems are very difficult. In this study, we develop a new IP-based multi-channel video surveillance system which is integrated surveillance camera, emergency call devices, communications devices, various sensors in the elevator, DVR, ODM, and can manage all devices by two-way communication and integrated interface. And we evaluated the performance of the developed system.

      • Functional MR Imaging을 利用한 鍼刺戟 效果의 映像化 硏究 : 至陰 刺戟이 大腦視覺皮質에 미치는 影響을 中心으로 The Effects of BL 67 Acupuncture Stimulation on the Visual Cortex of Brain

        李惠貞,朴희濬,金弘烈 WHO COLLABORATING CENTRE FOR TRADITIONAL MEDICINE 1998 東西醫學硏究所 論文集 Vol.1998 No.-

        The purpose of this experiment is to find the methods of visualizing the effects of acupuncture. The limbs are main active areas of Qi. Therefore, the activation of Qi in these areas can have an effect on the trunk and the sensory organs. Ji-Eum(BL67) is known to have special relationship to the eyes and optical functions. Based on this theory. I chose 10 volunteers, first I compared visual activation and no visual activation, and next I look at the acupuncture stimulation at BL67 and no acupuncture stimulation. The first experiment was conducted with light to the eyes using checker board 8Hz flash and observed the time course data. Next I stimulated BL67 using the same time course paradigm as I did during the visual stimulation. The results of acupuncture stimulation were distinct and showed much similarity to the result of visual stimulation. The cerebral cortex is composed of almost only neuronal cell bodies, and the sensory signals at any part of the body are transferred along the nervous system to the brain. But the signal changes at the visual cortex which were stimulated through acupuncture of BL67 cannot be explained through the neuronal pathway of acupuncture pain signal. Therefore It suggests that this phenomenon occur due to another mechanism which might give a hint to the still unknown mechanism of Meridian. As a control group, stimulation of non-acupoint has been performed, but there were no clear changes at the brain cortex. This leads to the conclusion that this stimulation of the visual cortex is done specifically through stimulation of BL67. The results of this experiment are like this; 1. Visual stimulation through checker board 8Hz flash induced 6.94±0.74% positive signal changes at the visual cortex of the brain. 2. Acupuncture stimulation at BL67 induced 6.58±0.74% negative signal changes at the visual cortex of the brain. 3. Acupuncture stimulation at Non-acupoint did not induce any significant signal changes at the same area.

Acupuncture stimulation at BL67 induced 6.58±0.59% negative signal changes at the visual cortex of the brain. 3. Acupuncture stimulation at Non-acupoint did not induce any significant signal changes at the same area.
