지난날 우리기업들은 수많은 경영혁신 기법들을 도입하여 추진해 왔지만 그것들은 기대를 충족시키지 못하고 관심에서 멀어져가 버린 경우가 많다. 경영혁신 도입 실패는 많은 경우, 기법 자체의 문제라기보다는 그것을 실행하는 기업의 문제라고 보아야 할 것이다. 주요한 실패 원인의 하나는 경영혁신이 기업의 전략과 정렬되지 못했다는 것이다. 본 논문에서는 경영혁신 기법들을 경쟁전략의 틀에 맞추어 분석, 분류함으로써 전략과 경영혁신기법의 통합모델을 제시한다. A lot of companies experience failure in innovating their management practices even though they adopt various innovation techniques that seem to be valid and competitive. The primary reason for this failure can be found from the fact that the company failed to conduct innovation techniques in harmony with their business strategies. In this context, we focus on developing a unified framework that innovates the management practices in accordance with the business strategies of the company. For this purpose, we first analyse numerous innovation techniques and business strategies, and then classify them into several clusters in terms of 'innovation technique-strategy" match. Therefore, the result of this work can be used as a guide to derive competitive innovation techniques that are compatible with the underlying business strategies.

Capacitation of mouse spermatozoa in vitro is brought about by epididymal secretions released into the m-Tgrode medium at the time of sperm collection. Epididymal mouse sperm suspension achived by centrifugation were preincubated for a total of 120min with aliquants being removed at 5, 30 and 120min. By gently centrifugation and resuspending in fresh medium, the fertilizing rate of unwashed 5-and 30-min suspensions was increased such that 30-min washed samples did not differ significiantly from full capacitated, highly fertile 120-min unwashed samples. When epididymal suspension was added fertilization of cumulus intact oocyte was markedly inhibited, although fertilization of zona free oocytes was unaffected. Washing sperm suspensions preincubated in the absence of $Ca^{2+}$ with the subsequent introduction of exogenous $Ca^{2+}$ resulted in a significant increase in fertilization rates over equivalent unwashed samples.
