As the concept of open source extends beyond the scope of software, many companies are also introducing business models using open source concepts. This study is a study on how to create a web-based open-source platform using a 3D printer and aims to create an open-source platform modeled on the Kidults community where users are highly willing to participate. The research method established the direction of initial platform production by collecting basic data through the usability of the platform and Toy design preferences and propensity analysis through research on open source use cases by various companies and user surveys in the Kidults Community. Features unique platform Toy sources that are freely reinterpreted by the user and re-shared and sold to the platform. Research should continue to boost user motivation by activating communities within the platform.

The method and process of research and development (R&D) is changing when we develop artificial intelligence (AI), and the way R&D results are dispersed is also changing. For the R&D process, using and participating in open-source ecosystems has become more important, so we need to be prepared for open source. For product and service development, a combination of AI algorithm, data, and computing power is needed. In this paper, we introduce ETRI AI Strategy #4, "Expanding AI Open Platform." It consists of two key tasks: one to build an AI open source platform (OSP) to create a cooperative AI R&D ecosystem, and another to systematize the "x+AI" open platform (XOP) to disperse AI technologies into the ecosystem.

본고는 크게 두가지 주제로 구성이된다. 첫번째로는 HTML5 기반의 mobile Web application platform 구조에 대해서 상세히 소개한다. Web application platform은 기술 구조상 mobile OS에 내재되어 native형태로 배포되는 Browser engine을 포함한 platform 부분과 native Web platform 상에서 구동되는 HTML5 application framework 부분으로 구성된다. HTML5 application framework 구축을 위해 시장에서 널리쓰이는 open source로서 jQuery Mobile framework을 소개한다. 두번째로 해당 Web platform상에서 동작하는 Web application 개발시 부디칠 각종 성능 이슈 및 그것을 해결하기 위한 접근법을 다섯가지 기술 영역으로 나누어, 각 영역별로 적용 가능한 실기를 다룬다. 마지막으로 최적화시 사용가능한 각종 open source profiling 및 성능 최적화 tool에 대해서 소개한다.

The era of IoT in which all objects are intelligent and are connected to the internet has been started. In order to establish and activate an IoT eco system, open IoT services platform is very important. In this paper, we develop an open IoT services platform and verified the function by building a testbed. Our platform based on the open source hardware and commercial cloud services such as AWS which is a component of an open service IoT platform.

시스템 자체를 에뮬레이션 하는 Virtual Platform은 임베디드 시스템 개발 프로세스 과정 중 하나인 소프트웨어 개발의 시점을 앞당길 수 있어 Time-To-Market을 줄일 수 있다. 본 논문에서는 Virtual Platform에 리눅스를 포팅하고 벤치마크 프로그램을 수행하여 성능을 측정하였다. 또한 이를 임베디드 시스템의 실제 개발단계에서 사용되는 Prototype Machine과 완성된 시제품에 각각 매칭 될 수 있는 FPGA 와 PC의 성능과 비교함으로써 Open Source Virtual Platform의 대표 주자인 QEMU의 효용성을 연구하였다. 실험 결과, 전체적인 성능은 PC가 FPGA보다 약 5.27배, FPGA가 Virtual Platform보다 5.38배, PC가 Virtual Platform보다 약 28.36배 더 좋은 성능을 보였다.

Companies that use open source SW must comply with the "Open Source SW License" in order to use it freely. However, despite the potential legal responsibilities and risks associated with compliance, they do not know or neglect the risks. For this reason, cases of disputes, including license violations, are soaring. Recently, Open source SW license compliance platform services have been developed and actively utilized to address these issues. This study designed a business model for open source SW license compliance platform and conducted an economic feasibility analysis. The focus of the study is the establishment of a business model and the estimation of potential customers and actual purchase rates. For this purpose, we designed seven business model scenarios for promotion and sales period, and performed an economic evaluation using an expanded model of the Bass model, the Kalish model and the customer's maximum willingness to pay.

To cope with the rapid changes in the corporate environment, the creation of innovative output through various forms of collaboration have been discussed. For open collaborations, contributors who distribute to various countries and cultures are able to share knowledge via the internet without physical rewards or responsibilities. In this study, we focused on the open source software project, which is a representative open collaboration. We investigated the factors that affect the knowledge contribution of developers of various countries within the open collaboration platform. Specifically, we investigated the open collaborative nature of multi-culture developers by dividing cultures according to collectivism and individualism. We collected data on 26,604 developers using a python based web crawler for GitHub which is an open source software development platform, and conducted cross-cultural study. This paper contributes to the field of knowledge management by suggesting various impacts of antecedents such as hireability, and information exposure on knowledge sharing according to culture.

The interest on the Open Source Software(OSS) has been increasing as the Microsoft's latest Windows XP support ended. In this light trend, this study can contribute to the OSS marketing area. Specifically, it examined that the activation of online brand community about the OSS can affect to prosumer marketing of the OSS utilizing social media platform. In addition, the OSS social media platform users' loyalty for the OSS was investigated. The findings show that content, consumer support, UI, and reward among the activate factors of online brand community significantly affected to the activation of OSS social media platform. The brand reputation, however, was found insignificant to the activation of OSS social media platform. In addition, the activation of OSS social media platform can positively affect to their loyalty for the OSS. It means that participation to the social media activities about OSS and interaction with others in the network can help to form positive attitude for the OSS. In conclusion, the prosumer marketing utilizing social platform can be an important strategy as a new solution of the OSS business in the rapidly changing ICT ecosystem environment.

A virtual platform models a processor core and the peripheral devices constituting the SoC in software. Major companies utilize a variety of platforms for product development with optimal SW+SoC integrated system architecture design and IP reuse based Top-Down design flow using a virtual platform. In this paper, we propose a virtual platform based on OpenRISC, an open source RISC based core. The proposed virtual platform supports high speed emulation of approximately 20 MIPS using DBT (Dynamic Binary Translation).
