Short Korean article on lead user innovation

I contributed an article on lead user innovation to the monthly Journal of Marketing in Korea probably one and half year ago. Title was lead user innovation in the context of open innovation. Open innovation and lead user innovation has been often used interchangably but certainly these two areas are distinct in some point, and professor, Joel West in Sanjose University maintains this aspect. I strived to view the lead user innovation from the perspective of product innvation point and stresssed that lead user innvation would be an intriguing research subject from the juction of marketing and product innovation.
