In order to ensure the interoperability of products and technologies, companies apply standard technology in R&D but encounter various obstacles in this process, which they try to overcome through active standardization activities. Various studies have investigated the obstacles and coping strategies of companies in the R&D process. However, studies on the obstacles and coping strategies in the standardization process are insufficient, and the types of obstacles related to standardization, so a variety of studies are also needed on the types of activities. In this study, we tried to determine the types of obstacles related to standardization and to examine how these obstacles affect the standardization activities of companies. The analysis used the data from the 'National Standards Survey' which was conducted by the Korean Standards Association in Korea for companies engaged in the electrical, electronic, and information-related fields in Korea. The relationship between standard-related difficulties, needs and standardization activities was verified through structural equation modeling. The analysis results revealed that the standards-related disability issues have some influence on the standardization activities and the mediating effect by the necessity of the standard was investigated. We also found that many companies are making various efforts to overcome the barriers caused by standard activities. This suggests that a company can build a virtuous cycle structure by performing strategic actions to overcome obstacles by standardization activity and reducing the obstacles caused by standard-related research and development.

최근들어 반도체 제조업계에서는 반도체제조공정자동화에 대한 요구가 증대하고 있으며, 이의 실현을 위해서는 반도체 제조장비와 상위 컴퓨터간의 직접 접속에 의한 제조공정의 실시간 감시 제어가 선행되어야 한다. 본고는 통일된 통신규격의 부재로 야기되는 자동화의 장애요소를 해결하기 위하여 제정된 반도체 공정 자동화용 통신규격인 SECS(SEMI Equipment Communications Standard)의 주요 구성 및 기능에 대하여 기술한다. SECS는 컴퓨터를 이용한 반도체 공정 자동화를 효율적으로 실현하기 위한 유용한 수단으로 활용된다.

Increased network reliability is required as the size of communication network becomes larger and the bandwidth requirement is increasing. And preparing of backup path is required to protect the network from serious network failures in high speed network. In this paper, we construct multiple logical networks on a physical ATM network according to the ATM bearer service category(CBR, rt-VBR, nrt-VBR, ABR, UBR) defined by ATM Forum to support the required QoS(Quality of Service) and to manage the network more efficiently. We use backup path restoration algorithm rather than dynamic restoration to achieve rapid restoration when active path fails and we use fault management function in TINA. We propose a restoration scheme that is suitable for high-speed network.

최근 IT기술의 비약적인 발전과 더불어 사용자의 편의성을 극대화 시키는 웨어러블 컴퓨팅 기술이 주목을 받고 있다. 이러한 기술은 일반인뿐만 아니라 장애인들의 일상생활의 보조 도구에 활용되어 큰 도움이 될 것으로 예상된다. 본 논문에서는 시각 및 청각장애인을 위해 개발된 착용형 단말기들을 소개하고자 한다. 시각 장애인용 단말기인 SmartWand는 시각장애인용 지팡이에 부착하거나 손에 휴대할 수 있는 장치로, 시작장애인을 위한 보행 보조 및 색상과 명암 정보 인식 보조 기능을 갖춘 장치이다. SmarWand는 시각장애인이 보행 시 이용하는 기존의 지팡이로는 감지할 수 없는 전방의 장애물을 초음파 센서를 통해 탐지하여 촉각이나 음성으로 경고해주고, 물체의 색깔이나 주변의 밝기 정도를 측정하여 시각장애인에게 알려준다. 청각 장애인용 단말기인 SmarWatch는 손목에 착용하는 장치로서 아기 울음소리, 노크나 초인종 소리, 물 끓는 소리, 화재 경보 등 가정에서 발생하는 일상적인 소리를 인식할 수 있도록 해준다. SmartWatch는 입력 모듈의 마이크로 입력된 소리를 문선통신을 통해 컴퓨터로 전송한 후에 소리의 종류를 인식하고 적절한 제어신호를 다시 무선통신을 통해 전송받아 감지된 소리의 종류를 해당하는 진동과 시각정보로 표시해준다. 이런 착용형 단말기들을 통해 시각 및 청각 장애인의 일상 생활의 안정성과 편의성이 증대 되기를 기대한다.

As an increase in recent optical network-based IP services, GMPLS management framework becomes more important than ever before. In this paper, we propose the dynamic GMPLS path management algorithm, which can satisfy the users with their traffic engineering recovery requirements and find out the best backup service path under multiple link failures. To be more specific, we are deriving the soluble conditions of a backup path which is satisfied in a GMPLS network. In addition, through proposing the fast backup path selection algorithm, we can sufficiently satisfy a user's recovery requirement and minimally protect the suspension of the service against a link failure.

Effect analysis tool for space infrastructure has a role to give essential information which is needed to perform research systematically as effect analysis for satellites on earth orbit due to solar burst and statistical analysis for deriving key factor which is occurred anomalies to satellite. And retrieval function which is able to search domestic and foreign research data such as paper, report, journal and book related to satellite anomaly is also included. So this tool will be provided research environment for effect analysis from space environment to space infrastructure of earth orbit satellite. In this paper, it is shown design result for effect analysis for space infrastructure including DB design.
