The purpose of this research was to test the effects of entrepreneurship and technological innovation capability on new product performance in SMEs and the moderating role of absorption capability. For this study, Research data were collected through questionnaire instruments from the sample of 374 employees in 18 SMEs of metropolitan area. The 336 sample was selected and analyzed by hierarchical regression technique. The results showed that entrepreneurship and technological innovation capability had a positive effect on new product performance. And also found out absorption capability had the moderate roles between all the three factors of technological innovation capability factors and new product performance, but not between all the three factors of entrepreneurship and new product performance. With the research results, the implications for technical management of SMEs were discussed, and the directions for future research were suggested.

PURPOSES: This paper presents the results of computer simulations of roadside safety barrier, called by safety roller guardrail, consisting of rotational roller, rotation control plate, post and subsidiary members. The rotation roller and rotation control plate are made by EVA(ethylene vinyl acetate), and PE(polyester), respectively. METHODS: The occupant risk analysis has been carried out under vehicle crash condition for high containment level of SB-4 for the purpose of local road. Simulations are performed with the finite element code LS/DYNA-3D. RESULTS: The numerical results obtained by LS/DYNA-3D software from the viewpoints of vehicle stability, vehicle trajectory, occupant risk, etc. CONCLUSIONS: It is noted that not only impact severity is drastically reduced but also vehicle trajectory is improved due to the characteristics of energy absorption and rotation pattern of EVA rollers connected by control plates.
