As the advance of multi-platform and multi-channel online services, brokerages are now offering three representative online trading systems - HTS(Home Trading Systems), WTS(Web Trading Systems), MTS(Mobile Trading Systems). In this study we investigated and compared the impact of different systems on the performance of brokerages. Using the panel data of 29 brokerages of 4 periods, we empirically tested the impact of online trading systems and the commissions of trading services. We found out that there exist some differences between the impacts of online trading systems based on the platforms. HTS was identified as the main platform for online trading services. However the role of MTS was also significantly identified while WTS showed no significant impact on the brokerage performances. Commission also showed significant negative impact in case of HTS and MTS platforms. Finally, offering MTS was identified as the significant dummy variable influencing the performance of brokerages. The results provides some implication for the multi-platform strategy for online services.

온라인 연예 뉴스 기사의 연성화와 속보성 기사가 증가함에 따라 많은 사람들이 연예면 기사를 접하며, 연예인에 대한 평가를 내릴 수 있게 됐다. 연예인에 대한 평판은 소속된 연예인 자원을 최대한 활용해야 하는 연예기획사의 사업전략에 핵심적인 요소이나, 실시간적으로 대규모 기사가 올라오는 환경에서 어떤 뉴스 기사가 어떤 연예인에 관한 것인지 체계적으로 분석하는 것은 용이하지 않다. 본 논문은 연예 뉴스 데이터에서 언급되는 연예인의 언급량을 기준으로 해당 기사의 주제가 되는 연예인을 추출하고, 해당 연예인의 연예기획사로 연관짓는 연예 뉴스 키워드 분석 시스템을 제안한다. 본 논문에서 제안된 시스템을 통해 광고사 혹은 연예기획사 측에서 사업을 위한 참고 자료로 해당 연예인의 가치 판단을 할 수 있다. 이와 더불어 증권사나 투자자들에게 연예기획사의 전망을 예측하여, 투자 전략의 토대를 마련해줄 수 있다.
