Open Source Softwares(OSS) are increasingly deployed in several domains, many educational organization have tried to deploy the OSS LMS(Learning Management System). For deploying OSS LMS, customization for specific environment is critical requirement. In this paper, we implemented the supporting environment to integrate the Moodle and school information system for user and course management. It is the most important customization requirement for introducing the Moodle to school. Also, we implemented supporting environment for the most important requirement so that we verified the usability of our guideline. We applied our environment to verify the efficiency of customization process.

OSS(Open source software) pursues the freedom to have access to open source and offers several advantages, over the proprietary software, to enterprises. Based upon Rogers(1995)' innovation-diffusion process, we assume that attributes of innovations includes five characteristics of innovations: relative advantage, compatibility, complexity, trialability, and observability, and that firms' perceptions of these characteristics predict the rate of adoption of OSS. To test this hypothesis, we presents a survey result from 201 companies and institutions concerning the use of OSS. Statistical analysis shows that adoption is highly correlated with each of those characteristics of innovations, but the regression analysis indicates that only compatibility and observability have effects on the adoption of OSS. This implies that intrinsic value of OSS is important, but unless the appropriate service package for improving IT environment is provided, it is not easy to change the perspective of corporate customers more favorable toward OSS use. As a conclusion, the academic and practical implications are also discussed.

Korean military uses 'Tactical information communication network' to exchange information between units. In this study, we developed a media processing board for multi-party voice and video telephony based on open source software. On the other hand, in order to apply open source software for weapon systems and parts that are mounted on weapon systems, appropriate review is required according to the weapon system software development and management manual of the Defense Acquisition Program Administration (DAPA). In this study, the analysis of the requirement items was performed and the appropriate countermeasures were proposed for the open software applied to the media processing board with respect to 'the guidelines for the application of weapon systems to open source software', an appendix to the DAPA's manual.

The purpose of this study was to confirm the extent of the reduction in the total cost of ownership of the open source software in comparison to the commercial software installed for information system, PC and cloud computing. Accordingly, the actual reduction rates in the total cost of ownership, when open source software is installed in the information system, PC and cloud computing, were computed and analyzed for 51 companies in the area of information system, 18 companies in the area of PC and 6 companies in the area of cloud computing, which included government institution, educational institution and private enterprises. The results of expert survey illustrated that the reduction rates are (1)63.3% on the average for the 4areas of information system, namely, DBMS, WAS, Web and OS, (2) 59.4% on the average for the 6 areas of PC, namely, OS, Documentation Program, Back-up and Restoration, Screen Capture, Vaccine and Others and (3) 61.2% on the average for the 6 areas of cloud computing, namely, Virtualization, OS, WEM/WAS, DBMS, DFS and Cloud Management.

개정된 7차 교육과정의 정보 교과에서는 창의적이며 논리적 사고력을 바탕으로 한 문제해결 능력 함양에 중점을 두어 중등학교에 공통적으로 '문제해결방법과 절차'라는 대영역이 포함되었다. 이 단원의 내용 요소 중에 알고리즘에 대한 내용이 포함되어 있다. 알고리즘에 관련된 내용요소를 교육할 때 기존 연구가 부족하여 교사와 학생들이 활용할 자료와 소프트웨어가 충분하지 못한 실정이다. 본 연구에서는 개정된 중등학교 정보 교과의 알고리즘에 대한 내용을 분석하고, 이 알고리즘 교육에서 공개소프트웨어를 활용하는 방안을 제시한다.

최근 공개SW를 활용한 IT서비스가 활성화되고 있으며, 대표적인 서비스 유형으로는 소프트웨어 개발, 소프트웨어 유지보수, SI 및 SM, 리포지토리 서비스가 있다. 공개SW의 대표적인 장점 및 기대효과로는 가격 경쟁력 향상과 개발 생산성 향상을 꼽을수 있다. 하지만 IT 서비스 업체에서 공개SW를 활용할 경우 라이센스, 유지보수, 품질 및 호환성 이슈에 대해 정확히 파악하고 사전에 준비해야 한다. LG CNS에서는 최근 해외시장에 공개SW를 적극적으로 활용하여 IT 서비스를 제공한 사례가 있으며, 해당 사례를 분석한 결과 공개SW를 IT 서비스에서 활용할 경우 실제로 소프트웨어 비용 절감을 통한 가격 경쟁력 제고 및 개발생산성 향상의 효과를 확인할 수 있다. 국내 IT서비스 업체가 상대적으로 공개SW에 대한 인식이 잘 형성되어 있는 해외 IT 서비스 시장에서 공개SW에 대한 이해를 바탕으로 주요 이슈에 대해 미리 준비하고 이를 적절히 활용한다면 경쟁력을 확보하는데 도움이 될 것이다.

Open source software when promoting development in R&D has many advantages and is becoming an open software - based R&D projects continuously created in a number of countries. However, there are still limits to the creation of effective performance in R&D projects, as well as difficulty of the project implementation because it not yet established an appropriate management plan for the open source R&D projects in the public sector. Therefore, through investigating a number of previous studies and practices, we intend to enhance the effectiveness of the system by suggesting concrete measures for promoting and managing open source nature in a preperiodic point of view on the public sector open source software R&D projects.

Advance in Information and Communication Technology (ICT) is intensely influenced to increase importance of Software on global ICT industries. The trend of technological development has been transformed from hardware-oriented environment to software-oriented environment. This industrial transformation brought novel trend to Software market. Open Source Software (OSS) has been widely distributed for private uses. At the same time, many governmental offices are planning to expand the use of OSS. In this paper, we analyze the strength and weaknesses of OSSs for both Web and WAS servers based on 4 types of testing environments which are created by the combination of 5 selected OSSs. We anticipated to learn the optimal system architecture design for the next generation of V-World through this research.
