There has been a recent increase in the interest towards founding companies and in line with the South Korean Government's policy on start-up support, discussions are rife about the effect of entrepreneurship on the management and performances of these companies. To enhance the competitiveness of SMEs, it is expedient to acquire and deploy consistent entrepreneurship, differentiate corporate resources, ensure the appropriate utilization of resources and the integration of such factors in response to the changing environment. This research examines relationships among entrepreneurship, three components of corporate capabilities, dynamic capability and technical performance based on resource-based view and the dynamic capability theory. The authors also investigate the moderating role of corporate life cycle. To test the hypothesis, we conducted a survey on 352 technologies -innovative SMEs located in South Korea via professional research institutes. The findings confirm the hypothesis that SMEs' entrepreneurship has a positive effect on three kinds of corporate capabilities (e.g., marketing, R&D, operations capability), and it had a positive effect on dynamic capability, whiles dynamic capability also had an influence on technical performances. The findings also confirmed the hypothesis that corporate life cycle moderates the relationship between dynamic capability and technical performances respectively. The research implications for both practitioners and academicians are discussed.
This study was directed to finding an optimum extraction condition of genistein from the S. flavescens with supercritical carbon dioxide as a solvent. In this effort, effects of the extraction conditions including pressure, temperature and a co-solvent on the extraction efficiency were investigated. The aqueous ethanol and methanol solutions were used as co-solvents while the tested operating pressure and temperature ranges were from 200 bar to 300 bar and from 308.15 K to 323.15 K, respectively. The concentration of genistein was determined by means of HPLC equipped with a UV detector. From the results, it was observed that an increase in pressure led to the higher extraction efficiency. Further, methanol showed better performance as a co-slovent than ethanol. The DPPH radical scavenging activities were measured to compare antioxidant activities of S. flavescens extracts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
