  • The virtual reality(VR) technology can provide various stimuli, including, visual and auditory stimuli, simultaneously in the virtual environment and encourage the user to interact. Virtual reality is a set of computer technologies, which when combined, provide an interactive interface to a computer generated world. In this world the subject can see, hear and navigate in a dynamically changing environment in which he participates as an active player, by modifying the environment according to his will. Moreover, the subject can get a feeling for the virtual environment in much the same way as one feels real life situations. In the real world, a plethora of information from various modalities may be in conflict, and modulate each other to form an illusion. In this study we investigated whether a tactile illusion on a real hand could be evoked by a virtual stimulus, the time required to generate this illusion and its duration. This study shows that the illusion occurred, and that was correlated with presence score in the virtual environment.

  • With the rapid development of urban traffic system and fast increasing of vehicle numbers, the traditional centralized ways to generate the source-destination shortest path in terms of travel time(the optimal path) encounter several problems, such as high server pressure, low query efficiency, roads state without in-time updating. With the widespread use of smart cameras in the urban traffic and surveillance system, this paper maps the optimal path finding problem in the dynamic road network to the shortest routing problem in the smart camera networks. The proposed distributed optimal path generation algorithm employs the delay routing and caching mechanism. Real-time route update is also presented to adapt to the dynamic road network. The test result shows that this algorithm has advantages in both query time and query packet numbers.

  • A spectroelectrochemical system assembled with a white light source, bifurcated optical fiber, Oriel Multispec spectrograph, and a charge-coupled device (CCD) detector is described. The system is shown to be capable of acquiring a whole spectrum in the spectral range of 290-800 nm in 25 ms or a longer period during electrochemical experiments at reflective working electrodes such as platinum or mercury. The utility of the system in studying electrochemical reactions during the potential scan, galvanostatic electrolysis, or after the potential step is demonstrated.

  • The digital electronic switching system has some problems, when this system processes OAM(Operation, Administration And Maintenance) messages about the fault, the traffic, the account, and the performance, etc. , at the present. Therefore, we studied on Methods that could process OAM messages out of all digital electronic switching systems and, first of all, developed the MGS (Message Gathering System) to be able to accept and process the fault message of OAM messages out of all digital electronic switching systems in real time.

  • 인간면역결핍바이러스(Human Immunodeficiency Virus; HIV) 진단을 위한 초고속 실시간 PCR법을 개발하였다. 검출 대상의 DNA 염기서열은 495염기 HIV-1 특이 env 유전자(gi_l184090)및 294염기 HIV-2 특이 env 유전자(gi_1332355)를 사용하였다. 초고속 실시간 PCR은 microchip에 $6\;{\mu}l$의 PCR 용액을 탑재하는 $Genspector^{TM}$ (Samsung, Korea)을 사용하였으며, PCR의 각 회전 중 단지 두 단계(denaturation, annealing/extension)를 극단적으로 짧은 시간을 주어 수행하게 하였다. 융점분석을 포함한 30회전의 PCR 검색 시간은 총7분30초 이내에 완료되었으며, HIV-1 특이 117염기와 HIV-2 특이 119염기의 PCR산물은 최소 $2.3{\times}10^3$개의 각 env 유전자로부터 30회전의 2단계 초고속 PCR에 의해 성공적으로 증폭시킬 수 있었다. 이러한 초고속 실시간 PCR법은 HIV의 빠른검색뿐 아니라, 다른 병원채의 빠른 검색에도 유용하계 적용될 수 있을 것이다.

  • Design and implementation of monitoring and control system using dual-microprocessor node is presented for real time process. The proposed system is implemented with 2 of the single chip microprocessors in tightly coupled mode and results in speed up of $s_p=1.74.$ Under the assumption that the nodes are interconnected in multidrop. the overall system performance such as average throughout-delay characteristics and effective throughput are analyzed using M/G/1 gueueing model, and results show that the proposed node can be used to medium sized distributed monitoring and control system.
