The advance of IT brings various IT equipment which functions as creation, application, and distribution of digital contents, and its demand is increased in the market. As the world IT equipment market has grew steadily, some companies think of it as a good opportunity. But there is a entry barrier like IT Capabilities to the late movers. So some participate in the market, forming the technology alliance with a advanced company. Ironically, the market system set companies' partnership into rivalry. In this context, our study focused on strengthening late mover's competitiveness under the technology alliance. And we conducted the case study concerning the technology alliance, and showed a strategical implications. As a result, we found some challenges for late mover; price policy making by scientific demanding forecasting, preparatory research and management for brand identity and efficient contact points for customer management. We hope that results of the study will influence the development of digital contents industry.

Nowadays, SCM(supply chain management) is recognized as a efficient way to overcome the limits of asset and capability of one fun through the synergy effects comes from strategic alliance. Traditionally material management and logistics are recognized as a simple functional activity. But as the importance and needs of customer service are increased, gradually these activities are given to strategic role of cutting off the cost and increasing the sales. But unlike traditional alliance, for example technology alliance or holding facility in common, SCM has many difficulties in action because of differences in organization structure and management system between two firms. So in this paper, I will review literatures about the concept and constructing factor of SCM, the conditions for effective doing and strategic implications.

Patent litigation has been considered as a tool to protect and facilitate innovation. Ironically, yet, the misguided uses of patent litigation as a strategic tool for vigilance against competitors are acting as a hindrance for innovation. Previous studies show that the better the quality of a patent, the higher the chance of the patent being litigated. Therefore, it is particularly important for the innovating firms to take strategic precautions to minimize the risk of patent litigation. This study investigates the moderating role of firms' past alliance experiences on the relationship between patent quality and patent litigation from the perspective of a defendant. A unique dataset on patents, infringement lawsuits, and firm performances in the printed electronics industry confirms that firms' previous alliance experiences mitigate the impact of patent quality on infringement litigation. For instance, the results confirm that the presence of past alliance experience reduces the litigation rate by 33% for firms with median-quality patents. This paper makes two major contributions. First, it contributes to the literature on alliance experience by confirming its role as a reputation in mitigating future litigations. Second, this paper contributes to the literature on patent litigation by identifying a unique moderator, i.e., alliance experience, on the linkage between patent quality and litigation. An innovating firm is likely to become an alleged infringer under a false accusation. Therefore, this paper focuses on firms that partake in infringement lawsuits unwillingly. Despite the importance, to the best of our knowledge, this is the first study to investigate patent litigations from the perspective of defendants.

Recently, many internet firms have opted the strategic alliances with other on/off-line firms in order to gain and sustain their competitive advantages. Previous research on market reaction to such alliances, however, shows mixed results. Therefore, the purpose of this thesis is to analyze the announcement effects of the alliances among internet firms in the stock market. Focusing on on-line firms that have been outside the scope of previous research, this study applied the event study methodology and examined the cumulative abnormal returns(CAR) for 245 alliance announcements between October 1998 and May 2002. Further, this study conducted a survey to categorize various types of announcements and 40 usable returns has been analyzed. The notable results from this study include: 1) The strategic alliances announcements do not have statistically positive effects on stock prices of the announcing firms. 2) Contrary to the results of the previous research, the CARs associated with marketing alliances are higher than those with technology alliances. 3) The degree of fitness among firms' disposition, their alliance purpose, and alliance type chosen influences the performance of their alliances.

UWB는 2002년부터 FCC에서 상용을 허용한 이후 IEEE802.15.3a에서 DS-CDMA 방식과 MB-OFDM 방식을 논의해 왔으나 표준안 도출에 실패한 후 지금은 WiMedia Alliance와 UWB Forum에서 각기 표준화 진행중이다. Intel, Microsoft, HP 등이 주축인 WiMdeia Alliance는‘PAN 환경에서 장치간의 무선 멀티미디어 연결과 상호운용성’을 위하여 구성되었으며, 2003년 MBOA와 합병하여 MBOA 기술을 기반으로 하는 물리계층 및 MAC 계층 기능 규격을 ECMA 등에 표준으로 등록하였고, 그 외 표준화 단체에 표준안 채택을 위한 노력을 계속하고 있다. 또한 USB Forum, Bluetooth, IEEE1394 등에 MBOA 기반 응용이 사용될 수 있도록 노력하고 있으며, 2005년 MBOA 기반의 Certified Wireless USB 규격으로 UWB 시장을 선점하기 시작하였으며, Bluetooth 및 IEEE1394에서도 MBOA 기반 표준이 진행되고 있다. 본 고는 WiMedia Alliance의 최근 표준 활동과 WiMedia 규격을 활용한 국내.외 기술동향에 대하여 살펴보고자 한다.

IEEE802.15에서 표준화가 진행중인 WPAN(wireless personal network)은 개인영역 네트워크 혹은 근거리 무선 네트워크를 구축하기 위한 기술로, 개인용 컴퓨터, PDA, 주변기기, 휴대전화, 가전 등의 휴대나 이동 컴퓨팅을 위한 기술이다. IEEE802.15.1에서는 블루투스, IEEE802.15.4에서는 ZigBee를 위한 저속 WPAN(low rate WPAN) 그리고 IEEE802.15.3에서는 고속 WPAN(high rate WPAN)에 대한 표준화를 담당하고 있다. 본 고에서는 IEEE802.15 산하 TG3a에서 표준화 중인 Alt-PHY 기술로 경합을 벌이고 있는 MBOA(Multi-Band Orthogonal frequency division multiplexing Alliance) UWB(ultrawideband)에 대한 활성화를 꾀하고 있는 WiMedia Alliance의 시험인증 동향을 고찰하고자 한다.
