In recent years, venture capital funds in emerging Asian markets have witnessed significant growth. This study investigates the impact of institutional investors and intellectual property payments on venture capital fund using panel data from 8 emerging Asian countries and 13 developed countries over the 10-year period from 2011 to 2020. In emerging Asian markets, the results show that new institutional investors have a significant positive impact on the development of venture capital funds. Intellectual property payments has a significant negative impact on venture capital in emerging Asian Markets. On the other hands, in developed markets, new institutional investors and intellectual property payments do not have a significant impact on the development of venture capital funds. Furthermore, we find that market capitalization has a strong negative impact on venture capital fund investment in emerging Asian markets, unlike in developed markets. Rule of law has a strong positive impact on venture capital fund investment in emerging Asian markets. GDP growth in emerging Asian markets has a strong negative effect on venture capital fund in emerging Asian markets. These findings suggest that the factors affecting venture capital funds in emerging Asian markets are somewhat different from the developed markets. Therefore, future research on venture capital should consider the characteristics of emerging Asian markets.

The development of automotive technology and increased consumers demand changes in the criteria for evaluating the emotional quality of the vehicles, not only the car"s performance as well as noise and vibration from the vehicle and the sound quality of the vehicle has emerged as an important factor. These things include wind noise, door closing sound and sand noise (almost everything you can feel) and many research to improve this are actively conducted in recent years. In this paper, the sound quality factor of sand noise which affects the subjective evaluation is defined by Taguchi S/N ratios and the standard reference model which can be calculated from measuring sound is suggested by using T-method.
