클라우드 컴퓨팅은 정보가 인터넷 상의 서버에 영구적으로 저장되고 데스크탑이나 테이블 컴퓨터, 노트북, 벽걸이 컴퓨터, 휴대용 기기 등과 같은 클라이언트에는 일시적으로 보관되는 패러다임을 뜻한다. 가용성과 사용상의 편의에 대한 요구의 증가로 최근들어 빠른 속도로 발전하는 모습을 보이고 있다. 클라우드 컴퓨팅은 제공하는 서비스의 유형에 따라 IaaS(Infrastructure as a Service), PaaS(Platform as a Service), SaaS(Software as a Service)로 나뉜다. 이 중 IaaS는 인프라를 서비스로 제공하는 모델이다. 이를 구현한 오픈소스 클라우드 플랫폼으로 오픈스택과 클라우드 스택이 대표적이다. 시트릭스는 자사가 개발중인 클라우드 플랫폼인 클라우드스택을 아파치 라이센스로 전환하겠다고 발표했다. 이전까지 같은 종류의 클라우드 플랫폼인 오픈스택의 회원사로 참여하고 있던 시트릭스가 오픈스택 그룹에서 탈퇴하고 클라우드스택을 지원한다는 발표는 큰 관심을 받았다. 본 논문에서는 여러 오픈소스 클라우드 플랫폼 중 오픈스택과 클라우드스택을 비교해보고, 이를 통해 향후 오픈소스 클라우드 플랫폼의 발전가능성에 대해 고찰해보고자 한다.

Several multi-user online applications which are operated by the existing fixed terminals(PC) are being changed into online application based on multi-platform operated by the several PC, PDA and mobile phones to perform concurrent works due to the popularization of mobile devices recently. This paper proposed the infrastructure for network applications based on multi-platform. We also proposed the methods of consistency control based on multi-platform, update propagation protocols among diverse clients which take the asymmetry of computing power and network bandwidth among each client into account. Moreover, we implemented a chatting application based on multi-platform and it showed the proposed infrastructure and methods perform well.

COVID-19의 확산과 급속한 디지털 전환으로 인해 비대면으로 소통하고 정보를 교류하는 메타버스 플랫폼이 최근 많은 주목을 받고 있다. 하지만 새로운 플랫폼의 등장에도 불구하고 대부분 게임이나 상용 시스템 위주로 적용되고 있으며 학술정보서비스 영역에서의 적용은 요원한 현실이다. 본 연구에서는 기술의 적용 형태와 지향범위에 따른 메타버스의 '증강현실, 일상기록, 미러월드, 가상세계' 등의 4가지 유형과 메타버스 플랫폼 주요 현황을 살펴보고, KISTI에서 제공하고 있는 과학기술지식인프라 통합서비스 ScienceON과 연계하여 디지털 연구환경 조성과 개방형 협업연구 활동을 지원하는 메타버스 플랫폼 키온버스의 제공서비스 유형과 주요 기능 등 학술정보서비스 영역에서의 메타버스 적용방안을 제시하였다. 본 연구는 학술정보서비스에 적용된 메타버스 플랫폼의 사례로서 향후 메타버스 활성화에 기여할 것으로 기대한다.

미디어 플랫폼의 다양화로 인하여 다양한 교육방법이 시도되고 있으며, 특히 교육용기능성게임은 G-learning 베이스로 새로운 교육방법으로 제시되고 있다. 하지만 "게임"이라는 부정적 인식으로 인하여 저변확대가 이루어지고 있지 않다. 게임을 즐기고 자라난 게임세대들에 대한 인식전환과 교육용 기능성게임에 대한 교육적 효과검증을 통하여 교육용 기능성게임을 새로운 교육방법으로 활용하기 위하여는 사회적 인식전환과 저변확대가 우선순위이다. 이를 위하여는 일반인들에게 교육용기능성게임을 알릴 수 있는 대회를 활성화하여 인식의 전환과 효과를 직접 체험할 수 있도록 해야한다. 이를 위하여 국내외 교육용 기능성게임대를 분석하고 활성화 방안을 모색하여 새로운 교육패러다임전환에 기여할 수 있는 방안을 제시하고자 한다. 이는 향후 국내 교육용 기능성게임 유저를 확산시켜줄 뿐만 아니라, 새로운 교육적 방법으로 활용할 수 있는 계기를 제시할 것으로 보인다.

This paper presents a conceptual strategy and technologies for the digital transformation of design and construction of reinforced concrete (RC) structures. The development of an automated detail design strategy for RC structures is described. Integrated digital platform based on 5D BIM concept is proposed for the replacement of the current technology environment-based 2D CAD. Generally, the detail design development is labor-intensive and iterative. Effective automation of relevant aspects can dramatically improve productivity and accuracy. The proposed solutions for the automated BIM modeling based on the rebar and formwork detail design automation achieves the productivity and accuracy sufficient for site application. The platform integrates and manages the information flow between each solution or application and provides it to all participants of the project. Finally, it is expected that the proposed strategy and technologies can be further enhanced to achieve the productivity and accuracy needed for widespread site application and digital transformation.

New strategies in the automobile industry have been required with the advent of new green car era. This study examines how to develop the electric automobile industry among green cars effectively. It's necessary to change fragmentary relationship-based analysis focusing on stakeholders in the existing automobile industry into platform-based analysis. The purpose of this study aims to define an analytical framework for adopting a more developed industry platform. To this end, the following major issues are analyzed. First, what is the definition of industrial platform, why is it needed? Second, who participate in industry platform, what are the working factors of the platform? Third, who are participants in industry platform applicable to electric vehicle market and what are the working factors for electric vehicle industry platform? Fourth, this researcher derives analytic framework of electric vehicle industry platform based on related cases and discusses applicable measures for the framework.

The cloud services market is growing rapidly from the on-premises environment to the cloud computing environment and the domestic cloud software market in Korea is expected to grow at a CAGR of around 15%. In Korea, research teams are providing open cloud platforms using open source software under the government taking the initiative, which intends to enhance the reliability and functionality of open cloud platforms, provide users with a world-class open cloud platform-based and developer-friendly environment that is managed on heterogeneous cloud infrastructure and supported by full-lifecycle management of application software. In this paper, we propose a method to utilize CaaS in the open cloud platform, through incorporating the platform with the container orchestration platform. Finally, by providing users with the application runtime and container runtime, it presents how the two platforms can coexist and cooperate in the same ecosystem.

This paper is a study aimed at facilitating a comprehensive understanding of the music metaverse platform that will emerge in the era of Web 3.0 and exploring productive strategies for its construction. We examine the significance of the metaverse music platform from various perspectives and investigate the developmental process of digital music platforms from Web 1.0 to 3.0. Subsequently, assuming the emergence of metaverse platforms as a transition to Web 3.0, we align this transition with technological(VR technology, wearable devices, generative AI), cultural(digital avatars, fandom), and economic(NFT) discussions related to Web 3.0. These discussions are integrated with the developmental strategies of the metaverse music platform. Through this study, we hope to enhance the understanding of the metaverse music platform and provide insights into potential construction strategies.

Several multi-user online applications which are operated by the existing fixed terminals(PC) are being changed into online application based on multi-platform operated by the several PC, PDA and mobile phones to perform concurrent works recently. The contents of current online application based multi-platform are, however, very unsophisticated because the applications don't consider the simultaneous accesses of shared data by multi-user and also the asymmetry of computing power and network bandwidth among each client. This paper proposed the methods of consistency control based on multi-platform, update propagation protocols among diverse clients, object management techniques which take the characteristics of mobile clients into account. We also implemented a chatting application based on multi-platform and it showed the proposed methods perform well.

As data is evaluated as a key asset for digital transformation, efficient and stable management of data, smooth sharing data, and provision of services using data are also required in the defense. To support this, the Korean military is laying the foundation for the Military Artificial Intelligence Platform which is a defense data management infrastructure. In this paper, we examine the data strategies and data platform promotion directions of Korea and major advanced groups, and we look for suggestion and present the direction of development of the Military Intelligent Platform. We are expected that it can contribute to the establishment of a safe and efficient defense data management infrastructure for the Korean military.
