초고속 인터넷, 다양한 통신 기기, 신규 인터넷 애플리케이션 등의 확산으로 인터넷 상의 콘텐츠 트래픽 규모가 급격하게 증가하고 있다. 비디오와 같은 대용량 멀티미디어 콘텐츠 트래픽이 전체 트래픽에서 차지하는 비중은 날로 증가하여, 2014년에는 전체 인터넷 트래픽 중 90% 이상을 차지할 것이라고 예측되기도 한다. 따라서 트래픽의 대부분을 차지하는 콘텐츠 중심으로 네트워크 아키텍처를 혁신할 필요성이 대두되고 있다. 본 논문은 최근 급증하는 콘텐츠 서비스의 송수신 특성에 적합한 네트워크 아키텍처에 대한 학계와 산업체의 연구동향과 콘텐츠 네트워킹 관련 기술의 국제 표준화 동향을 고찰하고, 향후 실제 적용을 위한 이슈를 분석한다.

As companies seek lower cost and superior quality at the same time, which depend on improvement in product architecture, they need to critically consider product architecture as part of corporate strategy. This research investigated how product architecture and organizational capability affect innovative outcomes with using architecture framework. As a result, we were able to find out Korean shipbuilding company has put much effort on integral works such as development of FGSS(Fuel gas supply system), PRS(Partial Re-liquefaction System) and weight lightening for improving fuel efficiency. And this kind of integral ability was realized by organizational capability of Korean shipbuilding company based on interactive relationship with plant workers. In contrast, Chinese shipbuilding companies focused excessively on the standard design and the convenience of research and development made by central government, overlooking the need for fine-tuning. As a result, the fuel efficiency of Chinese LNG ships turned out to be 7-10% lower than those of South Korea with using the same modules and components.

It can be organized with PVRs and FC-AL for a high-quality TV content-sharing architecture. It is, however, not easy to configure a large community network with the FC-AL since it has a 7-bit address space with supporting up to 127 users. We, therefore, propose a novel scalable FC-AL multiple-loop architecture using shared disks, which does not need to use expensive and load-concentrated switches. In this article, our suggested architecture shows a superb startup delay, such as less than 20msec. In addition, it demonstrates outstanding scalability, such that the number of accomodable users increases almost linearly according to adding loops. Lastly, it reveals exceptional time-shifting hours, that is, which supports more than 140 hours with 1000 users.

The emergence of new business models software industry is demanding a change to technology that can cope quickly and flexibly. In this regard, microservices, which is being addressed as the architecture of the next-generation record management system, has emerged as an agile and convenient architecture. If record-management system with micro-service is developed, agility and expandability with basement of innovation can be ensured. The purpose of study is to suggest efficient ways when record-management system with micro-service is built. For this, tranditional architecture has been checked and main features of micro-service have been explained. Also, it was summarized that three points : 'Short history of micro-service', 'Maturity of technology' and 'Techical level of project team' have to be reviewed when record-management system with micro-service architecture is built. And we suggested some issues to consider when constructing the records management system applying microservices according to the domestic environment.

지난 몇 년간 서비스 공급업체, 주로 신생 업체는 새로운 광 스위치 (OXC)의 서비스 기능, 유연성 및 비용 상의 우위를 즉시 활용할 수 있는 미개척 네트워크 영역을 구축해왔다. 최근 시장 침체로 인해 서비스 공급업체 특히 신생 업체가 타격을 받고 있다. 이러한 상황으로 인해 지능형 OXC 사용을 중심으로 하는 새로운 전송 아키텍처의 도입 열기가 다소 가라앉았지만 결코 멈춘 것은 아니다. 분명히 광 스위칭 및 분산 지능 기반의 아키텍처는 계속 존재할 것이다. 기존 업체(ILEC, IXC, RBOC 및 PTT)를 비롯하여 많은 서비스 공급업체는 이 아키텍처의 혁신적인 기술 및 기능을 인정하고 받아들이고 있다.

RISC-V is a free and open ISA enabling a new era of processor innovation through open standard collaboration. Born in academia and research, RISC-V ISA delivers a new level of free, extensible software and hardware freedom on architecture, paving the way for the next 50 years of computing design and innovation. In this paper, according to the emergence of RISC-V architecture, we describe the RISC-V processor instruction set constituted by arithmetic logic, memory, branch, control, status register, environment call and break point instructions. Using ModelSim and Quartus-II, 38 instructions of RISC-V has been successfully simulated and synthesized.

The change in information technology demands drastic change in digital library service. This study defines what a social semantic digital library should consist of and proposes a new architecture that incorporates core functions needed in designing a SSDL. The SSDL supports semantic information processing based on metadata and ontology and is an innovation system that allows SSDL users to participate in generating new knowledge by interacting with existing metadata and ontology structures. This study designed a SSDL model that consists of five horizontal and two vertical structures.

This study analyzed how the subcontracting business relations and structures of cooperation affect the relationship skills (Outcome) that is divided into three steps. We analyzed integrated data every other year from 2005 to 2009. As a results, in the execution of technical cooperation trade relations have influenced the positive attributes, but recently their influence has been weakened. As for technical cooperation, the structure should alleviate the problem of the uneven performance of technical cooperation. We suggested that technical expertise and infrastructure make possible the culmination of the long-term technological competitiveness level.

Despite many previous studies on catch-up, understanding on the effect of product architecture developed by latecomers on the catch-up performance remains limited. On the other hands, in contrast to the semiconductor, ship building, and automotive industry, even if Korean industry and government have invested the development of numerical controllers for machine tools in the past four decades, the industry and government have failed to achieve catch-up. Therefore, we newly examine the effect of product architecture on the catch-up performance of the Korea by implementing comparative research with periods on the evolution of product architecture of Fanuc's numerical controllers, which have achieved the largest market share in the world. We found that Fanuc developed open modular architecture based numerical controllers and provided product with customization of user requirements as well as cost effectiveness. Consequently, Fanuc has sustained market leader position since the mid-1980s. However, despite all the efforts of the industry and government, we found that the Korea failed to develop open modular architecture based numerical controllers and could not achieve significant catch-up performance. Our findings provide important theoretical backgrounds for examining the catch-up performance as well as investigating the reason why latecomers failed to achieve market catch-up even if they accomplished technological catch-up.

기업 ICT (Information & Communication Technology) 인프라의 혁신을 위해 선행되어야 할 조건으로 유무선 네트워크 시스템의 통합을 들 수 있다. 최근 10년간 통신 사업자들을 중심으로 유무선 네트워크 통합과 통합된 네트워크를 효율적으로 관리하기 위한 망 관리 시스템의 통합이 추진되어 왔다[5][6]. 여러 개의 망 관리 시스템을 하나의 시스템으로 통합하면서 발생하는 문제점 중 하나는 데이터베이스의 종류와 개수가 증가하면서 사용자들이 원하는 망관리 정보를 쉽게 찾을 수 없다는 점이다. 이러한 문제를 해결하기 위해 본 논문에서는 다양한 종류의 데이터베이스와 연동하여 사용자가 원하는 메뉴를 쉽게 찾을 수 있도록 지원하는 검색 체계를 제안한다. 제안된 아키텍처는 유무선 통합 망관리 시스템 환경에서 사용자가 원하는 망관리 정보를 쉽고 빠르게 검색하는 기능 구현에 적합하다.
