In this paper, we proposed the compensation method to evaluate arousal level in different initial arousal states. Arousal level was measured by the relationship between IRI and Nz. Since Nz is affected by BI which is directly proportional to initial arousal state of subjects, the arousal level is underestimated To overcome this problem, we proposed the compensation method using modified Karolinska sleepiness scale, and determined compensation coefficients derived from this scale with five arousal levels. Applying these coefficients to portable arousal monitoring system, the proposed method in this paper could be useful for real-time evaluation and control of arousal level. As a result the developed system can detect and control the arousal state from initial drowsing sate.

The purposes of this study are to examine the influences of appraisal and reward on the activities of knowledge management and to search the strategies for effective appraisal and reward system to activate the knowledge management. The results of covariance structural analyses indicate that appraisal has a significant direct effect on reward and knowledge creation as well as a significant indirect effect on knowledge sharing via reward and knowledge creation. Reward has a significant direct influence on knowledge sharing. Knowledge creation also significantly affects knowledge sharing. Based on the results, the potential implications of effective appraisal and reward system to activate the knowledge management are discussed.

When we introduce knowledge management system in our organization, first of all, we need to change the way of motivating the members so as to voluntarily activate knowledge sharing activity For this, it is very important to establish fair evaluation and adequate reward system about knowledge contribution. In this study, I hypothesized a desirable evaluation and reward model for knowledge contribution on the basis of analysis of documents and cases concerning them in domestic enterprises and R&D institutes that adopted knowledge management. Also, I took a survey to analyze the response of the members of KAERI (Korea Atomic Energy Research Institute) about the evaluation and reward for knowledge contribution. I expect that the analysis results of this study can be applied very usefully in R&B institutes that want to introduce knowledge management.

The purpose of this study is to examine the causal relationships among leadership, appraisal, reward, knowledge quality, knowledge management system(KMS) quality, and KMS use. The results of data analysis by structured equation model(SEM) indicate that leadership significantly influences appraisal and reward. Appraisal affects reward too. Reward and knowledge quality affect KMS Use, but leadership, appraisal, and KMS quality don't affect KMS use. Based on the results, the theoretical and practical implications of this study are discussed.

This paper analyses an impact of wage scheme and transparency of performance evaluation on the productivity. The main findings in this paper are as follows: First, the effect of wage scheme based on seniority system on the productivity is worse off than the performance pay. Second, there is a positive relationship between an incentive and the productivity, but, in the case of firms which individually informs the results of performance evaluation to their workers, it shows the hump-shaped relationship. Third, though the wage scheme is based on the performance, if the evaluation system is not transparent, the impact of incentive on the productivity is disappeared. Consequently, this paper implies that the appropriate incentive and the transparent performance evaluation system are required so as to improve the productivity.

The purpose of this study is to investigate the influence of KMS(Knowledge Management System) on the performance of KMS by setting the factors affecting KMS 's management performance as knowledge information factor and management factor. And the moderating effect of evaluation and compensation on knowledge information factor, management factor and management performance. As a result of the analysis, it was analyzed that the knowledge information factor set by the knowledge adaptability, the reliability of knowledge information, and knowledge management process affects the definition of management performance. Among the management factors, organizationalization and cooperation factors influence definition Respectively. In the results of verifying whether assessment and compensation play a moderating role, it is found that knowledge compatibility of knowledge information factor, reliability of knowledge information, support of knowledge management process, knowledge sharing activity of management factor, cooperation has played a moderating role in business performance.

360 VR video systems has become important to provide immersive effect for viewers. The system consists of stitching, projection, compression, inverse projection, viewport extraction. In this paper, an efficient luminance compensation technique for 360 VR video sequences, where feature extraction and histogram equalization algorithms are utilized. The proposed luminance compensation algorithm enhance the performance of stitching in 360 VR system. The simulation results showed that the proposed technique is useful to increase the quality of the displayed image.

We study incentive structures of public developers and land owners in the process of public expropriations using a sequential game model. In the model, we show that there is an incentive for the public developer to give more compensation than just compensation that are defined by law. Also the model shows that there is an incentive for the land owners to revolt strategically against the public expropriation. Then an ideal authority delegation model is introduced to resolve the problems, where an independent appraiser determines the compensation for the expropriation. In the real world, improving the independence of appraisal process is critical to make the system closer to the ideal authority delegation model. So this paper concludes by making a few policy suggestions to improve the current appraisal system.

연인두 폐쇄 부전으로 보상조음이 있을 때, 말 명료도를 저하시킬 뿐 아니라 실제의 연인두 기능이 과소평가 될 수 있으므로 이에 대한 감별 및 언어치료가 필수적이다. 본 연구에서는 연인두 폐쇄 부전 환자들에서 보상조음의 출현율을 알아보고 어떤 음소들이 영향을 받는지 살펴보고자 하였다. 또한 연령과 과비성의 정도에 따른 차이도 살펴보았다. 1998년 3월부터 2003년 6월까지 삼성서울병원에서 연인두 폐쇄 부전으로 진단 받고 언어치료를 받지 않았거나 언어치료 경험은 있지만 일반화되지 않고 중단된 환자 105명의 조음 및 공명 평가 자료를 분석하였다. 연령은 평균 11.3세(2.1세부터 63세)였고 7세 이하의 아동집단이 65명, 성인집단이 40명이었다. 조음은 구강압력자음인 파열음, 마찰음, 파찰음에서의 보상조음의 유무 및 종류를 분석하였다. 과비성의 정도는 경도, 중도, 심도로 평가하였다.
