This study analyzes whether there are differences in the level of compensation and pay-performance sensitivity between venture firms and non-venture firms listed on KOSDAQ. To test the above mentioned purpose, this study uses 726 firm-year data listed on KOSDAQ from 2006 to 2009. The results are as follow: First, we find that managers' compensation level of venture firms are higher than non-venture firms. Second, pay-stock performance sensitivity is higher than pay-accounting performance sensitivity in venture firms. Overall, because venture firms give a lot of stock-option to managers, compensation level of venture firms is higher than other firms. Also, venture firms set higher pay-stock performance sensitivity than pay-accounting performance sensitivity to mitigate short-sighted decision.

This study examines the compensation scheme for the executives and risk-taking behavior in the Korean banks. Theoretically, shareholders prefer risky asset choice to the optimal one due to the limited liability feature of reward, and stock-based executive compensation may induce choices favorable to the shareholder. We empirically test this risk-taking hypothesis using Korean banks' data. Since only the stock option data is available under the current disclosure system, we limit our analysis to examine the relationship between the compensation through stock option and the risk of banks. The result provides no evidence that stock option compensations increase the risk of banks, which is contrary to the theoretical prediction and preceding studies in the US. This may be due to any factor that the executive reward data omit, or regulation effects on the bank management.

Using longitudinal data of 575 sample from 122 firms in large business conglomerates from 2001 to 2008, this study examines the impact of controlling shareholders' control-ownership disparity on executive compensation. The empirical study finds that controlling shareholders' control-ownership disparity is negatively related to the level of executive compensation and moderate negatively the relation between firm performance and executive compensation. This finding suggests that controlling shareholders' control rights in excess of ownership rights lead to decreased executive compensation in order to relieve the concerns of stakeholder about the potential agency costs of controlling shareholder, and have, on the other hand, entrenchment effects on the decision of executive compensation by decreasing its sensitivity on firm performance.

The purpose of this paper is to examine the relation between executive excesss compensation and credit rating. According to the prior research which show the negative effects of excess compensation on a firm's future performance, this paper expects the negative effect of excess compensation on credit rating. Using a sample of Korean listed non-financial firms from 2014 to 2019, I perform the multivariate regressions analysis of excess compensation on credit rating. I find that excess compensation is negatively related to credit rating when executive compensation exceed expected executive compensation. Moreover, I find that the result is constant when a fim belongs to small-medium business. These results show that credit rating is affected by executive excess compensation and the relation could be different by the type of firm's size. Therefore, this study contributes to the literature by suggesting the possibility that capital market is aware of negative effect of executive excess compensation.

Delay estimation must be simple and efficient, since millions or more delay calculations may be required during a timing-driven placement stage. We have developed a new Modified Elmore delay estimation method, which is significantly more accurate than the original Elmore delay by considering resistance shielding effects, but has the same order of complexity with that of Elmore delay. Experimental results show that the suggested technique can significantly reduce the error in estimated delay, from 31.6 ~ 145.2% to 2.5 ~ 22.7%.

Using 850 disclosures of individual executive compensation from 2014 to 2017, this study examines the impact of female auditors on the sensitivity of executive compensation-performance relation. The major findings as follow: First, Female auditors have positive effects on the sensitivity of executive compensation to performance, implying that when auditors are appointed to be females who are more ethical, of high moral development, risk averse and conservative as well, they play an efficient monitoring role in aligning executive compensation to performance. Second, the monitoring effects of female auditors on the sensitivity of executive compensation to performance are significant when they are full time employed, suggesting that gender-based differences are more likely to be realized on the condition that they are in position to commit to their jobs for their owns. The results overall support that female auditors exercise efficient monitoring roles in aligning executive compensation to performance in Korean listed firms. The research contribute to complement the study of gender effects on corporate decision making, which have been focused on gender diversity of the board, by providing empirical evidence of the impact of female auditors on the sensitivity of executive compensation-performance relation.

Today, people are exposed to the various noisy environments, such as in the buses, subway and supermarkets where there are a lot of people. The noise issue is getting more serious as people want to use portable sound equipment and mobile phones even under this noisy condition. People want to use the portable equipment to exchange the information freely and they set the volume as 15dB higher than the noise around them, which almost reach at 110 dB. That amount of sound can cause noise induced deafness to the users and another issue to the others as additional noise source. A Bone-conduction system can be a solution to reduce noise and enhance voice signal of mobile phone. In this paper, we propose the way of cancelling noise and enhancing speech signal of mobile phones, by installing bone-conduction feedback system with ordinary mobile phones. With this system, we can reduce the environment noise and enhance the voice quality of mobile phones. Using this method, we can enhance the signal by around 17 dB.

The wideband chirp signal generator to enhance the resolution of synthetic aperture radar of obtaining the earth observation image is needed. This paper deals with designing, manufacturing and testing the wideband digital chirp signal generator having high resolution for LEO earth observation satellite. The wideband digital chirp signal generator is implemented with the memory-map based structure which is mostly applied in the satellite, and consists of the digital module to generate the digital chirp signal and the RF module to perform the quadrature modulation. The I/Q signals stored in the memory of the digital module are D/A converted and delivered to be quadrature modulated with the reference signal of 1275 MHz in the RF module. Furthermore, the test bench and GUI to validate the signal generator function are also developed. It is found that the requirement of 144 MHz bandwidth for the digital chirp signal generator is well met. Finally it is noteworthy that the distortion occurred in the chirp signal generator was compensated by the pre-distortion compensation.

Clutch torque control is the key to the ride comfort improvement of a vehicle equipped with AMT (automated manual transmission). For such control, the torque transfer starting point, known as the "kiss point," should be indicated or at least estimated to compensate for the clutch torque. The kiss point changes due to wear, high temperature, and fatigue; as such, it should be estimated while the vehicle is being driven. In this study, the method of kiss point active estimation for an AMT vehicle with a dry-type clutch was devised. The kiss point is learned while the engine is in an idle state and while the transmission is at a neutral gear position. It is determined when the input shaft of the transmission starts to rotate by slowly engaging the clutch. The noise of the shaft speed signal during the slow engagement process is filtered for accurate control. The kiss point estimation at various clutch engagement speeds was analyzed via a vehicle test.
