The recent emergence of electronic commerce could provide different opportunities to small firms in overcoming part of their technological, environmental, organizational, and managerial inadequacies. However, recent research provided a gloomy picture about electronic commerce uptake and use in small firms. Until now few small flrms adopted electronic commerce. This phenomenon gives us several implications. One of the implications is a need to generate more research to small firms' uptake and use of electronic commerce. So, this research aims at what is determinants in small firms' adoption of electronic commerce, especially business - to - business(B2B). Several previous studies were identified various influential variables in adoption of small firms' electronic commerce. To some extent, by industries these variables may be different in influencing B2B adoption of small firms. This study selected fishery industry's wholesale firms as survey domain. Then, It selected some variables from previous studios and group them in several factors for consistently comparing variable's influential power. Through hierarchical influencing model of B2B adoption, managers who worked for fishery wholesale firms were surveyed. Among the first level's factors of the model, business factor was identified as the statistically most influential factor in B2B adoption. Technological factor and environmental factor at the frist level were identified as relatively less influential factors. Among the second level's factors of the model, it was statistically significant only that technological usefulness factor was more influential than technological burden factor in B2B adoption. And among the third level's factors of the model, it was identified that formal plan and task team for B2B, top management support, and mutual beliefs of inter - firms were statistically more influential than related variables in B2B adoption. These results give us some implications. First, fishery wholesale firms recognized B2B as a new business paradigm, and technological problems as not obstacles in adopting B2B. Thus it would be possible to activate the fishery B2B if they were guided to getting B2B benefits and B2B's relative advantages. Second, they considered the power of influential factors might be different by B2B stages. That is, top management support was more important in the B2B introduction stage, and formal plan and task team for B2B and mutual beliefs of inter - firms were more important in the B2B operation stage.

LVC(Live Virtual Constructive) 통합 훈련 체계는 대표적인 가상물리시스템 중 하나이다. LVC 훈련 체계를 구성하는 각 L,V,C 체계들은 서로 다른 시간 도메인, 해상도 및 동작 방식을 갖는다. 이에 각 체계의 이종 미들웨어들을 공통의 통신 미들웨어로서 통합하고, 연동 gateway (GW)를 이용하여 이종 체계를 연동하는 방안 연구는 매우 중요하다. 특히, LVC체계는 서로 다른 시간 도메인을 사용하고 있기 때문에 다른 체계 간 이벤트들의 인과성 보장과 시간 동기화에 대한 연구가 필요하다. 본 연구에서는 LVC 훈련체계의 통합 미들웨어로서 L 체계의 실시간 통신 미들웨어인 OMG DDS(Data Distribution Service)를 기반으로 HLA(High Level Architecture)/RTI(Run Time Infrastructure)기반의 시뮬레이션 시간을 사용하는 V, C 체계와 시간 차원에서 연동하는 방안을 제시한다. 본 논문에서는 HLA의 Time management 기능과 Clock Federate를 기반으로 DDS와 HLA 각각의 통신 개체인 파티서펀트(Participant)와 페더레이트(Federate)간 인과성을 유지하는 정밀한 시간 동기화 기법을 제안한다. 더불어, 각 미들웨어 상에서 실제 응용을 개발하여 제안한 방식에 의해 이종 체계 간 시간 제어 및 동기화가 이루어짐을 검증한다.
