The purpose of this study is to investigate the mediating effect on self-efficacy in the effect of the compensation system of caregivers on job satisfaction. The research method was analyzed with SPSS V22.0 on the data of 367 people surveyed of caregivers working at home welfare facilities and elderly care facilities in the metropolitan area. The result is as follows. First, it was found that the average monthly salary, satisfaction of compensation treatment, and fairness of compensation had a positive effect on job satisfaction in the compensation system of caregivers. Second, in the compensation system for care givers, it was found that monthly average salary, satisfaction with compensation treatment, and compensation process had a positive effect on self-efficacy. Third, it was found that the self-efficacy of caregivers had a positive effect on job satisfaction. Fourth, in the compensation system of caregivers, it was found that the monthly average salary, compensation treatment satisfaction, and compensation process had an effect on job satisfaction, whereas self-efficacy had a positive mediating effect. It revealed that the higher the average monthly salary, compensation treatment satisfaction, and compensation process in the caregiver's compensation system, the more positively the self-efficacy had, and this self-efficacy had a positive effect on the job satisfaction of the caregiver.

This paper introduces a derivation method of both P-SKIP and B-SKIP modes for illumination compensation in the multi-view video coding scheme. In this proposed method, mismatches between IC flag and IC offset in P-SKIP mode are removed, and also computational complexity is far reduced in B-SKIP mode in comparison to a multi-view video coding scheme. In simulation results, proposed method has the almost same coding efficiency in comparison with the referenced coding scheme. However computational complexity in 11m-time decoding process is tremendously reduced, such that the average number of blocks that should be processed in P-SKIP mode is saved in about 7.47%, and the average number of operations per block in B-SKIP mode is saved in about 50.36% and corresponding average decoding time per block is also saved in 46%.

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.

In this paper, we proposed the compensation technique that overcomes the limitations of the conventional approaches through summing up the bias terms between world's codebook and individual codebook vectors of feature parameters. But, mean compensation without condition can bring higher false acceptance. Therefore, the proposed technique compensates the channel mis-match condition by weighted bias sum using nonlinear function regarding to the distortion between speech and silence. The simulation results show that the FRR (flase reject rate) is decreased 14.95% when the proposed algorithm was applied.

본 논문에서는 저속으로 회전하는 모터의 속도를 추정함에 있어서 속도 관측기를 이용하고 적절한 보상을 통해 가속/감속 운전 시에도 속도 추정 성능을 개선시킨다. 가속도 정보를 이용한 보상을 통해, 모터 인코더카운터 값으로부터 발생하는 양자화 오차를 줄인다. 가속/감속 운전시 인코더 펄스에 의한 평균속도는 펄스가 발생한 시점에서 불연속일 수밖에 없게 된다. 제안된 방식은 이 불연속적인 평균속도를 가속도 보상을 통해 연속적으로 증감하는 보상된 속도를 얻고 이를 다시 관측기 입력에 보상하여 양자화 오차를 감소시킨다.

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.

Autonomous driving technology has recently made great progress with the introduction of deep reinforcement learning. In order to effectively use deep reinforcement learning, it is important to select the appropriate activation function. In the meantime, many activation functions have been presented, but they show different performance depending on the environment to be applied. This paper compares and evaluates the performance of 12 activation functions to see which activation functions are effective when using reinforcement learning to learn autonomous driving on highways. To this end, a performance evaluation method was presented and the average reward value of each activation function was compared. As a result, when using GELU, the highest average reward could be obtained, and SiLU showed the lowest performance. The average reward difference between the two activation functions was 20%.

본 논문에서는 모델 기반의 잡음 보상 방법인 PMC (parallel model combination)를 온라인상에서 적용하는 방법에 관해 논한다. PMC는 파라미터 보상시 미리 계산된 잡음 모델을 필요로 하며 파라미터 보상에 많은 연산을 요구하므로 온라인으로 모델 파라미터를 보상하기가 어렵다. 본 논문에서는 이러한 문제를 해결하기 위해 기존에 제안된 온라인 모델 보상 방법을 살펴보고, 기존 방법에서 보상 시간 문제로 제외한 PMC의 공분산 보상을 비교적 적은 연산량으로 수행하여 인식성능을 더욱 향상시켰다. 고립 숫자음 인식시스템에 백색 잡음을 SNR 0, 5, 10 dB로 가산한 평가 자료로 실험한 결과, 제안한 방식은 PMC를 적용한 경우에 비해 모델 적응 시간은 적게 걸리면서도 기존의 온라인 모델 보상 방법에 비해 평균 10%의 인식률 향상을 보였다.

In general, several moving regions with different motions coexist in a block located on motion boundaries in the block-based motion estimation. In this case the motion compensation error(MCEs) are different with the moving regions. This is inclined to deteriorate the quality of motion compensated images because of the inaccurate motions estimated from the conventional mean absolute error(MAE) based matching function in which the matching error per pixel is accumulate throughout the block. In this paper, we divided a block into the regions according to their motions using the motion information of the spatio-temporally neighboring blocks and calculate the average MCF for each moving mentioned. From the simulation results, we showed the improved performance of the proposed method by comparing the results from other methods such as the full search method and the edge oriented block matching algorithm. Especially, we improved the quality of the motion compensated images of blocks on motion boundaries.
