To develop computer and communication in the information society, difficulties exist in managing the enormous data manually. Also, loss of data due to natural disasters or hacker attacks, generate a variety of disasters in the IT securities. Hence, there is an urgent need for an information protection management system in order to mitigate these incidents. Information Security Management System has various existing frameworks for IT disaster management. These include Cyber Security Framework, Risk Management Framework, ISO / IEC 27001: 2013, and COBIT 5.0. Each framework analyses and compares the entry for IT disaster recovery from among the various available data. In this paper, we describe a single integrated management scheme for fast resolution of IT disasters.

오늘날 사람들은 PC, 테블릿, 스마트폰 등 다양한 모바일기기를 이용하여 시간과 공간의 제약 없이 인터넷에 접속하여 전자금융 서비스를 편리하게 이용하고 있다. 이렇게 전자금융 서비스를 편리하게 이용하고 있지만, 사용자의 금융정보도 온라인을 통해 전송되고 있어서 이를 노린 다양한 해킹위협에 노출 되어 있다. 더욱이 금전적 이득을 노리고 불법적으로 금융정보를 탈취하는 등의 전자금융 이용자를 대상으로 하는 악의적인 목적의 다양한 해킹공격이 발생하고 있다. 이러한 해킹위협에 대응하기 위하여 OTP, 보안카드 등의 인증매체를 사용하고 있으나, 여러 서비스 제공자에 접속하기 위하여 다수의 인증매체 를 발급해야 하는 불편이 뒤따르고 있어 통합인증기술에 대한 요구가 증가하고 있다. 국내외 표준화 기구에서 활발하게 추진하고 있는 전자금융 통합인증기술은 스마트환경에 적합한 다양한 인증기술을 통합하여, 사용자와 여러 서비스 제공자가 공동으로 이용할 수 있도록 하는 것을 목표로 한다. 통합인증기술은 크게 여러 사용자와 서비스 제공자를 통합하여 서비스를 제공할 수 있는 프레임워크와 사용자인증 등에 필요한 OTP, BIO 등 다양한 요소 인증기술, 그리고 서비스 제공에 필요한 보안 요구사항으로 구분할 수 있다. 본 논문에서는 통합인증 프레임워크, 요소 인증기술, 보안 요구사항의 국내외 표준을 분석하고 표준화의 동향을 알아봄으로써 다양한 환경에서 안전하고 편리하게 사용할 수 있는 통합인증기술을 전망해본다.

Recently, the concern of IT-in-Agriculture convergence technology that combines information technology and agriculture is increasing rapidly. Especially, the crop cultivation related prediction services by spatial data mining (SDM) can play an important role in reducing the damage of natural disaster and enhancing crop productivity. However, the data conversion and integration procedure to acquire the learning dataset of SDM for the prediction service need a lot of effort and time, because of their heterogeneity between distributed data. In addition, calculating spatial neighborhood relationships between spatial and non-spatial data necessitates requires the complicated calculation procedure for large dataset. In this paper, we suggest a SOA-based data integration framework that can effectively integrate distributed heterogeneous data by treating each data source as a service unit and support to find the optimal prediction service by improving productivity of learning dataset for SDM. In our experiment, we confirmed that our framework can be effectively applied to find the optimal prediction service for the frost damage area, by considering the case of peach crop cultivation in Icheon in Korea.

For Knowledge Information Governance, integration search mechanism of Knowledge Information is required in various industries. But when Knowledge Information system constructs in each professional field, it developed and used its own metadata format. Accordingly, if distributed information system searches using metadata, heterogeneous problems are occurred among metadata. For integration search, it needs a consistency management of metadata. Therefore, this paper defines a standard metadata that represent standard metadata as surveying a used metadata in each field systems. Also, we propose a metadata registry integration framework for Knowledge Information Governance. It enables an integration search service without a metadata modification of existing system. Through the proposed framework, it can registries and manages efficiently the existing metadata. Also, it enables a semantically extended search using semantic relation between metadata.

UPnP AV Framework automatically integrates and manages various AV devices that are connected to network as an important component in home network. Therefore, user can access and control AV contents at any time. But, other existing home entertainment systems target multimedia service support that is based on multimedia home server system. In this paper, we propose an integrated home entertainment system (u-MUSE system) that supports remote control service. It can manage application in remote AV device or control AV contents directly in home network environment. The proposed system sufficiently performs role of control center for electronic devices in home via integrated system control and AV contents playback service.

최근 시스템의 컴포넌트화 경향은 인터넷 환경이 보편화되면서 플러그앤플레이(plug and play) 형태로 조립하여 재사용하려는 기업의 요구에 가장 핵심적인 패러다임으로 등장하고 있다. 따라서, 기업은 기존의 레거시 시스템을 컴포넌트화하여 유지보수뿐만 아니라 새로운 시스템 도입에 있어서도 유연성 및 확장성을 용이하게하기 위한 재공학 솔루션을 필요로 하고 있다. 따라서, 본 논문에서는 레거시 시스템을 소프트웨어 컴포넌트화하기 위한 재공학 프레임워크를 제안하였다. 이 프레임워크는 컴포넌트 개발 방법론에서 필요한 절차와 Robert C. Seacord와 John Robert가 제안한 레거시 시스템 현대화 방법론을 통합하여 제시하였으며, 프레임워크의 각 단계는 레거시 시스템의 분석 단계, 컴포넌트화 방법 결정 단계, 마지막으로 컴포넌트로의 변환 단계로 이루어져 있다. 각 단계에서는 다시 세부 절차와 이에 필요한 제반사항을 기술하여 레거시 시스템을 소프트웨어 컴포넌트화하는데 있어서 필요한 절차와 가이드라인을 상세하게 제공하고자 한다.

MPEG-4에서는 다양한 객체를 취급하기 위하여 시스템 부분(Part1)이 차지하는 비중이 MPEG-1이나 MPEG-2에서 보다 훨씬 높아졌다. 이러한 MPEG-4의 시스템 부분을 구현한 참조 모델을 IM1이라고 한다. IM1에는 다양한 오디오/비디오(A/V) 객체를 수용하기 위하여 디코더 프레임워크를 마련하고, 어떤 A/V 객체든 이 프레임워크에 맞추어 디코더를 구현하면 IM1 프리젠터에서 플레이가 가능토록 하고 있다. 현재 IM1 버전 3.8에서는 H.263 비디오, G.723 오디오, JPEG 이미지, AAC 오디오를 지원하고 있다. 이 논문에서는 MPEG-4 비디오 디코더를 IM1 디코더 프레임워크를 맞추어 설계, 수정한 내용을 기술하였다.

In this paper we design and implement a management framework base on JMX to control and manage ubiquitous home networks. To do this, we organize the ubiquitous home network test-bed that consists of information electronics and sensor devices. In the test-bed network, we implement the management framework which can control and manage various applications and devices in home network environment. In addition, it can also define and add new services easily. Moreover, it is possible to provide various management interfaces with multi-protocols. The framework is formed to integrate legacy management systems readily.

The testing time and cost of developed software can be reduced by automation of the whole or part of testing process. Since the testing automation tools to be used currently have been developed without their interoperability, test case information such as test procedures, test data, and expectation of test results generated at the stage of test execution cannot be shared and reused in other testing automation tools, In order to reduce testing time and cost, in this thesis, we have proposed a software testing automation framework which makes it possible to share and reuse the test case information generated in testing process. To prove the availability and effectiveness of proposed testing automation framework, three testing automation tools that are available in current market were experimented by the test scenario. As a result of experiment, the testing time and cost could be reduced by sharing and reusing the test case information in software testing automation framework.

Since the advent of Six Sigma in 1980's, Six Sigma is widely used in various industry areas, such as manufacturing, financial, government, and service, and proves its innovation ability and value by providing lots of success stories. Several researches have been conducted to adopt Six Sigma for Software Development and Software Quality Assurance-Software Six Sigma. Although the wide use of Six Sigma, there is no software tool to support the execution of Six Sigma Project. For this reason, the Quantitative Six Sigma Project Management is required to support for measuring and analyzing Six Sigma Projects, storing and reporting the results from Six Sigma Projects, and managing Six Sigma Projects through the whole process of, DMAIC or DMADV. In this paper, we introduce the design and implementation of a Quantitative Six Sigma Project Management Framework and Tool. The execution of Six Sigma Project based on Six Sigma Project Management Tool benefits the quantification, the systematization, and the integration.
