개개인의 데이터가 비즈니스적으로 중요하지 않을 수 있지만, 대량으로 모으면 그 안에 숨겨진 새로운 정보를 발견할 가능성이 있는 데이터의 집합체로 빅데이터 분석 활용 사례는 점차 늘어나는 추세이다. 빅데이터 분석 기술 중 전통적인 데이터 분석방법인 하둡(Hadoop)은 예전부터 현재에 이르기까지 정형 비정형 빅데이터 분석에 널리 사용되고 있는 기술이다. 하지만 하둡은 배치성 처리 시스템으로 데이터가 많아질수록 응답 지연이 발생할 가능성이 높아, 현재 기업 경영환경과 시장환경에 대한 엄청난 양의 고속 이벤트 데이터에 대한 실시간 분석이 어려운 상황이다. 본 논문에서는 급변하는 비즈니스 환경에 대한 대안으로 오픈소스 CEP(Complex Event Processing)기반 기술을 사용하여 초당 수백에서 수십만건 이상의 이벤트 스트림을 실시간으로 지연 없이 분석가능하게 하는 실시간 분석 시스템을 개발하여 병원 ERP시스템에 적용하였다.

Today's Software Systems are becoming bigger, larger and more complex than ever before. To develop largerscale projects, it is required that many experts of different fields participate and cooperate in the same project. So, it is an applied area of CSCW(Computer Supported Cooperative Works} that centers around methodologies and tools that enable cooperative works by geographically distributed people engaged in all aspects of product development. In this paper, we designed a multi-user cooperative works platform, SPACE(Software Platform for distributed Application sharing under Cooperative Environment} as a infrastructure that support to CSCW based system development for telecommunication and information system. SPACE has a fully distributed architecture under Windows 95 environment, has an application sharing mechanism enabling collaborative use of mteractive application adapt to a mixed GUI sharing technology which capture GUI and screen information, and also, an event sharing technology that has a replicated architecture.

Many organizations operate security systems and manage them using the intergrated secutity management (ISM) dechnology to secyre their network environment effectively. But current ISM is passive and behaves post-event manner. To reduce cost and resource for managing security and to remove possbility of succeeding in attacks by intruder, the perventive security management technology is required. In this paper, we propose PRISM model that performs preventative security management with evaluating the security level of host or network and the sensitivity level of information asset from potential risks before security incidents occur. The PRISM can give concrete and effective security management in managing the current complex networks.
