원자력산업살리기협의회 회원기업 대표들은 7월 20일 국회 정론관에서 기자회견을 갖고 "탈원전 정책과 원자력 기업이 상생할 수 있는 길을 마련해 줄 것"을 호소했다. 협의회는 성명서를 통해 "원자력산업은 기술집약적 중소기업형 산업으로 기자재분야는 소재와 부품공급사의 90%가 중소기업"이라며 "신규 원전 건설 계획 백지화와 신고리 5 6호기 건설 중단 방침으로 약 700여개 원자력 공급업체와 95개의 원도급사 그리고 512개 하도급사와 협력사 등이 불안과 일자리 박탈 우려로 밤잠을 이루지 못하고 있다."고 읍소했다. 원자력산업살리기협의회는 무진기연 등 원자력 관련 중소기업 200여개사가 회원으로 가입돼 있다.

MMDS 방식은 세계적으로 약간의 차이는 있지만 거의 2.5∼2.7GHz 주파수 대역을 사용하는 무선 CATV 전송 서비스 방식으로 현재 사용되고 있는 비디오 전송 방식 중 가장 경제적인 방식이다. 또한, LMDS는 아직 실험용 수준인 반면 MMDS는 이미 세계 67개국에서 500만 이상의 가입자를 확보하고 있으며 미국, 캐나다 등에서도 이미 상용화되었지만 특히 신규 CATV 도입국(남미, 중미, 호주, 태국 등)에서 유선 CATV의 대체 수단으로 각광을 받고 있다. 그러나, 상대적인 대역 제한 및 50W 정도의 출력에서 50∼60Km의 반경을 커버하므로 양방향 기능에 있어서는 제한적인 단점이 있다.

이제는 유비쿼터스이다. 초고속 인터넷이나, 휴대이동전화는 신규 가입자를 확보하기가 쉽지 않다. 이미 시장은 포화 정점에 머물러 있다. 새로운 시장 또는 서비스를 찾고 있으며, 이의 화두는 통합과 유비쿼터스이다. 위성 DMB, 휴대인터넷, 양방향 디지털 방송, 무선 랜 등등... 여기서는 Indoor AP를 이용한 무선랜 서비스를 Outdoor 용 Smart AP를 통해 확산을 꽤 하고자 한다.

This paper is to study the effects of some PSTN(public switched telephone network) related services on PSTN usages. We found a strong relationship between the number of subscribed services and PSTN usages. The more a user subscribes, the more he/she spends on PSTN. We also found a relationship between the number of subscriptions and whether to subscribe a new introduced service. A user with more subscriptions is likely to adpot a new introduced service.

In this paper, we propose and the call admission control mechanism that can improve the capacity of the wireless system for the non-uniform traffic load distribution based intelligent information in multiple cellular CDMA environment. The number of mobile stations that can be served simultaneously in a base station is limited by the amount of total interference received in CDMA system. Further, the average number of mobile stations in each cell may not be uniformly distributed. In this paper, considering this factors, the call admission control mechanism using the effective bandwidth concept is adapted to improve the system capacity of non-uniform traffic load distribution based intelligent information. Thus, the bandwidth for a new call can be varied dynamically for reducing the blocking rate of new calls and the dropping rate of handoff calls. The suggested call admission control mechanism is experimented through simulation by dynamically assigning the bandwidth to new and handoff calls. The simulation results show that the proposed call admission control mechanism can accommodate more mobile stations than the other methods in multiple cellular CDMA environment.

European economic integration and geographical enlargement brought change in the intra-european trade flow and a trade structure. The first, an european enlargement contributes to the increase in intra-european trade, but its effect relatively becomes smaller successive enlargement. The second, the intra-industry trade increases in the intra-european trade according as an european economic integration and enlargement make possible the economy of scale. In the intra-industry trade, the horizontal intra-industry trade decreases and the vertical intra-industry trade increases. The third, the Western Europe's trade is generally an intra-industry trade, the trade of Southern Europe, Central and Eastern Europe is an inter-industry trade. But the South Europe's trade and Central and Eastern Europe's trade change from the inter-industry trade to the intra-industry trade.

In this paper, we propose the call control scheme that can improve the capacity of the wireless system for the non-uniform traffic load distribution and the multiple types of services in multiple cells CDMA system. The number of mobile stations that can be served simultaneously in a base station is limited by the amount of total interference received in CDMA system. Further, the average number of mobile stations in each cell may not be uniformly distributed. Considering this factors, the call admission control scheme using the effective bandwidth concept is adapted in this paper.

Cloud storage service has the potential to be a core infrastructure for the future mobile and Internet service; thus related service providers have been investing in it and trying to attract as many users as possible. In addition, those need to find out what motivates the users to keep using their service not only to attract new customers but also to secure their subscribers. Therefore, this study will examine its relationship with user's motivation based on the extended TAM model with external variables for objective research about continuous use of cloud storage service. As a result, it was found that personal innovativeness, self efficacy, functional attributes, and psychological switching cost influence the continuous use of cloud storage service. Also, it is expected they can guide service providers to the right track when setting up their business strategy in the future.
