  • 본 논문에서는 학습자와 교수자간의 상호작용을 극대화하여 웹 상에서 효과적인 학습이 일어날 수 있도록 하는 기초전기회로 가상실험실을 자바 애플릿을 이용하여 구현하였다. 제안된 가상 실험실은 크게 실험원리학습실, 모의실험학습실, 자바가상실험학습실 및 가상실험실 관리 및 평가시스템으로 구성되어 있어 학습자로 하여금 흥미를 유발하여 전기회로실험을 간단한 마우스 조작만으로 수행하여 예비실험 결과를 데이터베이스에 저장하여 PHP를 이용하여 예비보고서 형태로 작성하여 학습자로 하여금 출력하여 프린트할 수 있도록 하였다. 본 논문에서 구현된 효율적인 기초전기회로 가상실험실은 수많은 방법중의 하나로써 향후 많은 수정과 보완이 이루어지리라 기대하며 기존의 교육시스템에서 발생되는 문제를 상당부분 보완할 수 있을 것으로 생각된다.

  • 임상병리과 정보관리시스템은 임상병리과에서 검사결과를 관리하는데 필수적인 요소이다. 저자들은 일반혈액 검사실의 전반적인 업무와 백혈구 감별검사에 대해 개인용 컴퓨터인 IBM 486 PC의 호환기종과 SCO foxbase 데이터베이스를 사용하여 일반 혈액검사실 정보관리시스템을 개발하였다. 사용한 컴퓨터는 주 기억용량이 16MB이고 하드디스크가 210MB, 9개의 RS-232C를 가진 IBM 호환 486 개인용 컴퓨터이고, 출력은 24핀 도트 프린터를 사용하였다. 이 시스템은 두대의 자동혈구분석기와 연결하여 검사결과를 자동으로 입력받고 병원의 주 컴퓨터와 API 기능을 사용하여 검사정보 및 검사결과를 전달할 수 있도록 하였다. 프로그램의 개발은 SCO foxbase에 내장된 Xbase 언어를 사용하였으며, 병원 주 전산기와 자동혈구분석기와의 연결은 C언어를 사용하였다. 이 시스템은 저렴한 비용으로 일반 혈액 검사실의 전산화를 구축할 수 있어 향후에 추진될 임상병리과 전체의 정보관리시스템을 구축하는데 일부분이 되고 다른 병원에서 임상병리과 전산화를 구축할 때에 모델이 될 것으로 사료된다.

  • This paper proposes an adaptive multimodal in-vehicle information system for safe driving. The proposed system filters input information based on both the priority assigned to the information and the given driving situation, to effectively manage input information and intelligently provide information to the driver. It then interacts with the driver using an adaptive multimodal interface by considering both the driving workload and the driver's cognitive reaction to the information it provides. It is shown experimentally that the proposed system can promote driver safety and enhance a driver's understanding of the information it provides by filtering the input information. In addition, the system can reduce a driver's workload by selecting an appropriate modality and corresponding level with which to communicate. An analysis of subjective questionnaires regarding the proposed system reveals that more than 85% of the respondents are satisfied with it. The proposed system is expected to provide prioritized information through an easily understood modality.

  • Virtualization technology has been widely applied in the area of computer security research that provides a new method for system protection. It has been a hotspot in system security research at present. Virtualization technology brings new risk as well as progress to computer operating system (OS). A multi-level perception security model using virtualization is proposed to deal with the problems of over-simplification of risk models, unreliable assumption of secure virtual machine monitor (VMM) and insufficient integration with virtualization technology in security design. Adopting the enhanced isolation mechanism of address space, the security perception units can be protected from risk environment. Based on parallel perceiving by the secure domain possessing with the same privilege level as VMM, a mechanism is established to ensure the security of VMM. In addition, a special pathway is set up to strengthen the ability of information interaction in the light of making reverse use of the method of covert channel. The evaluation results show that the proposed model is able to obtain the valuable risk information of system while ensuring the integrity of security perception units, and it can effectively identify the abnormal state of target system without significantly increasing the extra overhead.

  • Coordinated multi-point (CoMP) transmission has been regarded as a potential technology for LTE-Advanced. In frequency division duplexing systems, channel quantization is applied for reporting channel state information (CSI). Considering the dynamic number of cooperation base stations (BSs), asymmetry feature of CoMP channels and high searching complexity, simply increasing the size of the codebook used in traditional multiple antenna systems to quantize the global CSI of CoMP systems directly is infeasible. Per-cell codebook based channel quantization to quantize local CSI for each BS separately is an effective method. In this paper, the theoretical upper bounds of system throughput are derived for two codeword selection schemes, independent codeword selection (ICS) and joint codeword selection (JCS), respectively. The feedback overhead and selection complexity of these two schemes are analyzed. In the simulation, the system throughput of ICS and JCS is compared. Both analysis and simulation results show that JCS has a better tradeoff between system throughput and feedback overhead. The ICS has obvious advantage in complexity, but it needs additional phase information (PI) feedback for obtaining the approximate system throughput with JCS. Under the same number of feedback bits constraint, allocating the number of bits for channel direction information (CDI) and PI quantization can increase the system throughput, but ICS is still inferior to JCS. Based on theoretical analysis and simulation results, some recommendations are given with regard to the application of each scheme respectively.

  • Football (soccer) is one of the most popular sports in the world. A huge number of people watch live football matches by TV or Internet. A football match takes 90 minutes, but viewers may only want to watch a few highlights to save their time. As far as we know, there is no such a product that can be put into use to achieve intelligent highlight extraction from live football matches. In this paper, we propose an intelligent editing system for live football matches. Our system can automatically extract a series of highlights, such as goal, shoot, corner kick, red yellow card and the appearance of star players, from the live stream of a football match. Our system has been integrated into live streaming platforms during the 2018 FIFA World Cup and performed fairly well.

  • Real Time Simulation (RTS) has long been used in the nuclear power industry for operator training and engineering purposes. And, Online Simulation (OLS) is based on RTS and with connection to the plant information system to acquire the measurement data in real time for calibrating the simulation models and following plant operation, for the purposes of analyzing plant events and providing indicative signs of malfunctioning. An OLS system has been developed to support PWR operations for CPR1000 plants. The OLS system provides graphical user interface (GUI) for operators to monitor critical plant operations for preventing faulty operation or analyzing plant events. Functionalities of the OLS system are depicted through the maneuvering of the GUI for various OLS functional modules in the system.

  • MPEG-21은 사용자가 다양한 멀티미디어 데이터를 네트워크상에서 생성, 변형, 전달, 소비하기 위한 통합적 멀티미디어 프레임워크를 정의한 국제 표준이 다. MPEG-21 DIA(digital item adaptation)는 멀티 미디어 데이터를 사용자의 환경, 단말기 특성, 네트워크 특성에 대한 정보를 기술할 수 있는 표준을 정의하고 있다. 본 논문에서는 DIA에서 정의한 여러 가지 적응 변환 중 사용자의 관심 영역을 중심으로 한 의미론적 변환 엔진을 구현하였으며, 이에 대한 실험결과를 제시한다 기존의 변환 방법이 비디오 프레임의 전체 크기, 해상도 화질을 조정하였다면, 의미론적 변환은 사용자의 관심 영역을 중심으로 변환을 수행함으로써, 사용자의 관심도를 반영할 수 있는 장점이 있다.
