Based on the Deep Q-Network(DQN) algorithm of reinforcement learning, an active fault-tolerance method with incremental action is proposed for the control system with sensor faults of the once-through steam generator(OTSG). In this paper, we first establish the OTSG model as the interaction environment for the agent of reinforcement learning. The reinforcement learning agent chooses an action according to the system state obtained by the pressure sensor, the incremental action can gradually approach the optimal strategy for the current fault, and then the agent updates the network by different rewards obtained in the interaction process. In this way, we can transform the active fault tolerant control process of the OTSG to the reinforcement learning agent's decision-making process. The comparison experiments compared with the traditional reinforcement learning algorithm(RL) with fixed strategies show that the active fault-tolerant controller designed in this paper can accurately and rapidly control under sensor faults so that the pressure of the OTSG can be stabilized near the set-point value, and the OTSG can run normally and stably.

The reinforcement of the token, which is based on the token economy currently applied in blockchain-based cryptography, plays a critical role in forming the cryptographic-related ecosystem. Therefore, in this paper, it was investigated the reinforcement principle of token supporting the Token economy for blockchain model. In order to create a healthy ecosystem based on the reinforcement system principle, it is necessary to find ways to secure scalability by seeking consensus between the participants and the market economy structure so that it can generate an influx of more participants than seeking to maximize profits of certain people. Desirable behavior is defined as an action required by ecosystem participants that have the property of making the token ecosystem sustainable, and to do so, each individual receives appropriate incentives (rewards) when taking this action, ultimately encouraging voluntary participation and action by all participants in the ecosystem to optimize the interests of both individuals and participants. The expected benefit of this study may contribute to the establishment of various business models based on the principle of the reinforcement system.

This paper proposed the strategy learning method by means of the fusion of Back-Propagation neural network and Q learning algorithm for two-person, deterministic janggi board game. The learning process is accomplished simply through the playing each other. The system consists of two parts of move generator and search kernel. The one consists of move generator generating the moves on the board, the other consists of back-propagation and Q learning plus $\alpha$$\beta$ search algorithm in an attempt to learn the evaluation function. while temporal difference learns the discrepancy between the adjacent rewards, Q learning acquires the optimal policies even when there is no prior knowledge of effects of its moves on the environment through the learning of the evaluation function for the augmented rewards. Depended on the evaluation function through lots of games through the learning procedure it proved that the percentage won is linearly proportional to the portion of learning in general.

The purpose of this study is to design the compensation model by analyzing the compensation level for advanced science and technology manpower. The result of this study can be summarized as follows. First, advanced S&T manpower has preferred not only economic rewards, but also non-economic rewards which comprises both social reputation, self-satisfaction for job and other aspects of life. Second, the way of what high grade human resources in S&T have preferred to be rewarded differs among agencies. While professors in universities prefer research environment, researchers working for GRIs(Government-funded research institutes) want to have job stabilization and researchers in companies want to have higher monetary reward. Third, two main factors to change their occupation have been turned out to be monetary reward and social reputation. It means that the compensation system should satisfy what advanced S&T manpower at GRIs and companies need upgrading their social reputation.

These days, virtually every mobile game has a daily quest system. Daily quest is a great tool that can attract game players by providing daily rewards as the player conducts designated missions. However, conducting similar tasks repeatedly has a risk of becoming tedious duties, and maintaining an enjoyable daily quest is critical in enhancing the overall experience of a game. Based on the awareness on the need for academic research on daily quest systems, this study categorized the types of quests systems implemented in the current mobile games, observed how preferred type differs by player's propensity, and analyzed how motivation of a player can be improved using quest types. The results are (1) the staged rewards after each clearance of a task improve a player's motivation, (2) players with high autonomy should be given a freedom to choose their own quests, and (3) players who values their playing skills higher are motivated by providing a feedback on the completion of a task.

This research is interested in organization members' knowledge contribution, along with the requirement for the effective knowledge management as a critical corporate asset. We consider the performance appraisal and reward system on knowledge sharing as a key issue for the successful knowledge management. Analyzed will be the interactive relationship among the performance appraisal and reward system, individual knowledge contribution, and organizational knowledge contribution effectiveness. This case study is based on in-depth interviews in the consulting industry recognized as a knowledge-integrated industry. The purpose of this research is to examine how firms evaluate and reward organization members' knowledge contribution, to define how fim1s utilize IT for the knowledge management, and to show how the performance appraisal and reward system influence organizational knowledge contribution effectiveness. Besides, other determinants for knowledge contribution effectiveness are defined. It is recognized that knowledge contribution effectiveness is positively related to non-monetary rewards and informal appraisals. As for the future study, we recommend the empirical research based on several propositions developed in this study.

Background: The efficient knowledge management in hospital organization is generally known as the important activities relevant to employees' knowledge sharing behavior and work performance. This research examined factors affecting employees' knowledge sharing behavior and work performance in top 4 university hospitals. This study is based on individual factors such as incentives, reciprocity, behavioral control, and subjective norms. Also, there are organizational factors such as CEO support, learning climate, IT system, rewards system, and trust. Methods: Data was collected from employees who are working at 3 hospitals university in Seoul and 1 university hospital in Gyeonggi-Do through the self-administered questionnaires. A total of 779 questionnaires were analyzed by PASW SPSS ver. 18.0. (SPSS Inc., Chicago, IL, USA). Results: The significant variables affecting knowledge sharing behavior are behavioral control (in individual factor) and CEO, IT system, and trust (in organization factor). Also the significant variables affecting work performance are incentives, reciprocity, subjective norms, and behavioral control (in individual factor) and CEO support, IT system, reward system, and trust (in organization factor). Conclusion: The personality and organization characteristics factors is important to improve knowledge sharing behavior and work performance of hospital employees. Therefore, to make more efficient knowledge management is to build and system knowledge sharing culture, system, and leadership and to develop practical strategies.

First introduced in 1977, Korean health care system reached to national coverage in short period of time never seen before in any other countries, and rated as successful system protecting the health of the public at relatively low price. However, despite those positive evaluations, some of fraudulent medical organizations or pharmacies are hindering the sound development of the national health care system with meticulous false billing exaggerating the number of patients or the days of their treatment. To prevent aforementioned nursing home fraud and false billing, the misconduct should be punished as subject to the criminal law and severally punished for fines and payments which far exceed the expected amount of illicit gains as it is basically violation of criminal fraud, other than the forced return of illicit gains based on civil laws. Furthermore, the Health Insurance Review and Assessment Service should strengthen and complement the fraud investigators, the review process, and the professional training to raise the detection rates. It might also want to review ways to implement whistleblower rewarding system and rewards for evidences of healthcare fraud to overcome the limits of external review.
