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.

본 논문은 2인용 보드게임의 정보에 대한 전략을 학습할 수 있는 방법을 역전파 신경회로망과 Q학습알고리즘을 이용하여 제안하였다. 학습의 과정은 단순히 상대프로세스와의 대국에 의하여 이루어진다. 시스템의 구성은 탐색을 담당하는 부분과 기물의 수를 발생하는 부분으로 구성되어 있다. 수의 발생부분은 보드의 상태에 따라서 갱신되고, 탐색커널은 αβ 탐색을 기본으로 역전파 신경회로망과 Q학습을 결합하여 게임에 대해 양호한 평가함수를 학습하였다. 학습의 과정에서 일련의 기물의 이동에 있어서 인접한 평가치들의 차이만을 줄이는 Temporal Difference학습과는 달리, 기물의 이동에 따른 평가치에 대해 갱신된 평가치들을 이용하여 평가함수를 학습함으로써 최적의 전략을 유도할 수 있는 Q학습알고리즘을 사용하였다. 일반적으로 많은 학습을 통하여 평가함수의 정확도가 보장되면 승률이 학습의 양에 비례함을 알 수 있었다.

최근에 서비스되는 모바일 게임들은 대부분 일일 퀘스트 시스템을 갖고 있다. 일일 퀘스트는 매일마다 반복적으로 수행할 수 있는 과제와 적절한 보상을 제공하여, 플레이어에게 게임의 플레이 방향을 알려주면서 접속을 유도할 수 있는 훌륭한 장치이다. 그러나 비슷한 과제의 반복적인 수행은 자칫하면 지루해질 수 있어 플레이어들의 동기부여를 고려한 일일 퀘스트에 대한 연구는 게임 경험 향상에 중요한 주제이다. 본 연구는 일일 퀘스트에 대한 학술적 논의가 매우 부족함에 대한 인식을 기반으로, 현재 서비스 중인 모바일 게임의 일일 퀘스트 유형을 정리하고, 플레이어의 성향에 따라 어떤 일일 퀘스트 유형을 선호하는지, 어떤 유형에서 동기를 더욱 향상시킬 수 있는 지를 분석하였다. 그 결과로 다음 세 가지를 도출해 내었다. 첫째, 일일 퀘스트를 클리어할 때마다 단계적으로 추가 보상을 제공하여 플레이어들의 동기를 향상시킬 수 있다. 둘째, 플레이 성향에 따라 선호하는 일일 퀘스트의 유형이 다를 수 있으며, 자율성을 중요하게 생각하는 플레이어들은 자신이 직접 퀘스트를 선택할 수 있는 기회를 통해 동기를 향상시킬 수 있다. 마지막으로, 숙련으로부터 더욱 동기 부여를 받는 성향의 플레이어들은 퀘스트를 모두 완료했다는 피드백으로 동기를 향상시킬 수 있다.

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.

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.
