The main purpose of this research is to investigate the impact of compensation on job satisfaction. The study is designed to determine whether perceived internal equity acts as a mediation role in affecting the relationship between compensation and job satisfaction. This study also aims to explore the role of supervisor support in affecting employees' perception of equity toward the compensation. A total of 157 samples was obtained for the data analysis as a quantitative approach. The results of the data analyses revealed that both extrinsic and intrinsic rewards are positively correlated with job satisfaction. The results also showed that perceived internal equity acts as a mediating role in predicting variables of compensation and job satisfaction. The supervisor support does not moderate the relationship between compensation and perceived internal equity. It is suggested that management's efforts must be made in compensation management in order to increase employees' job satisfaction and to improve employees' perception of equity.

한국천문연구원과 일본 국립천문대는 공동으로 한일공동VLBI상관기(Korea-Japan VLBI Correlator, KJJVC)를 개발하였다. 이 상관기는 최대 16 관측국에 대하여 16 세트의 자기상관 및 120 세트의 상호상관을 계산할 수 있다. 각 관측국당 최대 8,192 Mbits/sec의 입력 데이터를 처리할 수 있으며, 8,192개의 주파수채널을 갖는 상관 스펙트럼을 약 25.4 밀리초~수초의 적분 시간으로 출력할 수 있는데, 최대 상관 출력 속도는 1.4GB/sec이다. 한편, 이 상관기는 한국우주전파관측망(KVN) 뿐만 아니라 동아시아VLBI관측망 및 우주공간VLBI관측망의 관측 데이터도 처리할 수 있도록 설계 제작되었으며, 최대 지연 추적 범위는 ${\pm}35,000km$이며, 보상 가능한 최대 기선 속도는 7.5km/sec이다. 현재 다른 VLBI관측망에서 사용하고 있는 타 상관기의 경우 지연은 2차 미분까지 보상하고, 프린지 위상은 3 단계로 보상하고 있는 것에 비하여, 한일공동VLBI상관기에서는 지연은 3차 미분까지 보상하여 지연 잔차를 최소화하고 프린지 위상은 16 단계로 세분하여 보상 수준의 정밀도를 최대화하였다. 이러한 지연 보상 및 프린지 멈춤 알고리즘을 상세히 소개하고 그 특성 및 장점을 보고한다.

In this paper, we propose a compensation method of a non-ideal antenna array and a computationally efficient estimation method of the direction of arrival (DOA) for the antenna array. For DOA estimation, an antenna array is essential. By using the phase difference between the output signals of antennas, we can derive the DOA. In practice, however, mutual coupling between the elements of an antenna array change the beam pattern of each element and degrade the performance of DOA estimation. In the proposed method, we first estimate the DOA for the mid-subarray of the array, where all elements undergo relatively same coupling effect. We use the estimation of signal parameters via rotational invariance techniques (ESPRIT) algorithm to estimate the DOA. Then, we expand the array based on the estimated DOA by compensating the coupling effect. Simulation results show that the proposed method is effective when jamming to noise power ratio (JNR)is relative low.

In this paper, we investigated the effect of cross phase modulation(XPM) on compensation for WDM channel distortion due to chromatic dispersion, self phase modulation and XPM as a function of fiber dispersion coefficient and modulation format in 320 Gbps WDM systems. The considered WDM transmission system is based on mid-span spectral inversion(MSSI) compensation method, which has highly nonlinear dispersion shifted fiber(HNL-DSF) as nonlinear medium of optical phase conjugator (OPC) in the mid-way of total transmission line. We confirmed that the maximum channel input power resulting 1 dB eye opening penalty is reduced due to XPM effect on channel distortion, even if MSSI method was applied to WDM system. But, we confirmed that the effect of XPM on channel distortion becomes decrease as fiber dispersion coefficient of WDM system becomes larger. Futhermore, we confirmed that NRZ is better than RZ as a modulation format for similarly compensating overall WDM channels in WDM system with large fiber dispersion coefficient in order to minimize the effect of the XPM on channel distortion.

An effect of reward program related to promotional activity has the limitation of being concentrated on a short-term performance or of inducing temporary re-purchase. Accordingly, this study verified the influence of reward method upon consumers' response recovery centering on interactive effects of reward timing and reward intensity, in order to expand a research of dissatisfaction situation. As for the objective of this study, first, the aim is to verify the difference in the influence of economic, non-economic, and combined rewards, which are reward methods of dissatisfaction situation, upon consumers' cognitive response recovery and emotional response recovery. Second, the aim is to confirm a moderating role of reward timing and reward intensity in the effect of consumers' response recovery according to reward methods. To design a research, the perfect factor design between subjects in 3X2X2 was used. As a result of major research, first, there was a difference in the influence upon consumers' response recovery depending on reward methods. Second, the influence of reward method upon consumers' response recovery had a difference depending on reward timing. Third, the influence of reward method upon consumers' response recovery had a difference depending on reward intensity. Consumers' response recovery level was confirmed to have the greatest influence in the combined reward. This study has a significance in newly applying the reward timing, in the dissatisfaction situation which is addressed in the general reward program. Through this study, the aim was to support the empirically analytical results of prior researches and to expand its role in several angles.

Multipath diversity reception is applied to the compensation of the distortion of channel, which occurs in transmission of data at rapid speed. DS/BPSK systems are composed of the equipment with reception structure combined with a compensation algorithm to diversity branch. The efficiency of the system is evaluated from the point of view of average bit error rate according to SNR. In order to remove intersymbol interference, this algorithm is applied to time-invariant channel at every diversity branch with the number of L. As a result, the average bit error rate is saturated by $10^{-2}$ at the conventional compensation algorithm.
