The eligibility is used to solve the credit-assignment problem which is one of important problems in reinforcement learning. Conventional eligibilities which are accumulating eligibility and replacing eligibility make ineffective use of rewards acquired in learning process. Because only an executed action in a visited state is learned by these eligibilities. Thus, we propose a new eligibility, called the weighted eligibility with which not only an executed action but also neighboring actions in a visited state are to be learned. The fuzzy Q-learning algorithm using proposed eligibility is applied to a cart-pole balancing problem, which shows improvement of learning speed.

강화학습은 에이전트가 환경과의 상호작용을 통해 획득한 경험으로부터 제어 규칙을 학습하는 방법이다. 강화학습의 중요한 문제 중의 하나인 신뢰 할당 문제를 해결하기 위해 기여도가 사용되는데, 누적 기여도나 대체 기여도와 같은 기존의 기여도를 이용한 방법은 방문한 상태에서 수행된 행위만을 학습시키기 때문에 학습 자정에서 획득된 보답 신호를 효과적으로 사용하지 못한다. 본 논문에서는 방문한 상태에서 수행된 행위뿐만 아니라 인접 행위들도 학습될 수 있도록 하는 새로운 기여도로써 분포 기여도를 제안한다. 제안된 기여도를 이용한 퍼지 Q-learning 알고리즘을 역진자 시스템에 적용하여 학습 속도면에서 기존의 방법에 비해 우수함을 보인다.

온/오프라인상으로 개인이 적격성 증명을 해야 하는 경우, 자격 충족 여부를 알 수 있으면 충분함에도, 기존 어떤 방식도 개인정보 제공 과정에서 어쩔 수 없이 소유자 신원을 드러내거나 불필요한 추가 정보를 노출하게 된다. 본 논문에서는, 개인정보의 성별, 생년, 출생지 등 불변인 항목 중, 소유자가 적격성 검증자에게 꼭 필요한 항목(들)만을 각각 다수 선택지 중 하나의 값을 지정하여 제공하는 방식을 제안한다. 이 방식에서, 적격성 검증자는 정보 소유자의 동의로 블록체인에 저장된 개인정보 항목들 조합에 접근할 수 있으며, 접근 내역을 다시 블록체인에 기록 요청하여 안전하게 저장할 수 있다. 제안 방식을 통해 사용자는 자신의 신원이 드러나거나 개인정보가 과다하게 노출될 것을 우려하지 않으며, 적격성 검증자는 필요한 정보만을 확인하되 그 기록을 별도 저장하지 않고도 추후 기록을 조회할 수 있게 된다.

오늘날 우리의 경제규모 확대와 세계화의 흐름에 의해서 국내에 장기 거주하는 외국인이 날로 증가하고 있다. 장기거주외국인들은 본국의 국적을 그대로 가지면서 생활하지만 체류국의 정치적 결정에 의해 생활에 중대한 영향을 받고 있다. 외국인에게 참정권이 인정되지 않는 것은 국민주권의 원리상 당연한 것으로 치부되어 왔지만 국민주권원리의 동요, 선진외국의 동향, 국가와 지방자치단체의 성질상의 차이, 혹은 외국인의 실태 등을 근거로 해서 외국인이기 때문에 참정권이 부정된다는 주장에 대해 반론이 꾸준히 제기되어 왔다. 지방선거에서 외국인에게 선거권을 허용한 이상 피선거권만을 제한하는 현행 공직선거법의 태도는 특별한 이유 없이 선거권과 피선거권을 차별하는 불합리한 입법태도라고 지적할 수 있다. 선거권과 피선거권을 달리 취급해야 할 합리적 이유가 없는 데도 외국인에게 피선거권은 부여하지 않는 것은 불합리한 차별이다. 본고에서는 외국인에 대한 참정권부여를 둘러싸고 벌어지는 헌법적 논점에 관하여 서술하고 일본을 비롯한 유럽각국의 입법례를 살펴본 다음 외국인 참정권 중에서 피선거권을 중심으로 우리 공직선거법에의 도입가능성을 검토해 보고자 한다.

Background: Comprehensive medication management is essential to achieve safe and optimal drug use for the elderly in long-term care facilities (LTCF). This study aimed to develop eligibility criteria for "Comprehensive medication management program in LTCF" using the RAND/UCLA Appropriateness Method (RAM). Furthermore, we attempted to estimate the number of beneficiaries who met the criteria by analyzing the National Health Insurance claims data. Methods: Twelve criteria were selected initially. We composed a panel of 14 experts with expertise in long-term care. We conducted two survey rounds to reach a consensus. Rating for appropriateness and decision regarding agreement were applied per RAM. We analyzed the National Health Insurance data to estimate the number of LTCF residents who met each eligibility criterion. Results: Of the 11 items agreed upon, ten items were determined to be appropriate. In 2018, 83.6% of 165,994 residents of LTCF met one or more eligibility criteria. The largest number of subjects met the "New residents of LTCF" criterion, followed by "Take high-alert drugs" and "Chronic excessive polypharmacy." Since the items evaluated as most appropriate by the expert panel and those with a large number of subjects were similar, we confirmed the external validity of our criteria. Conclusion: It is worth noting that this is the first attempt to establish the eligibility criteria for medication management in LTCF. Further preliminary research is needed to identify the selected subjects' drug-related problems and revise the criteria according to the results.

During the progression of this study, we visited 17 medical institutions. These medical institutions underwent inspection for facility eligibility of national inpatient isolation units to care for patients. Seventeen consultation meetings were held to gather expert opinions, and conferences were held with the medical institutions and local levels of government. Based on these facts, we established a field application model of the criteria of safety-management and conducted a study on this method in order to create more scientific and systematic safety-management criteria including criteria regarding facilities maintenance and methods of equipment inspection. According to an analysis on the 17 medical institutions examined, facility eligibility of 17 national inpatient isolation units was found to be 78.3% on average. Through analysis of the present domestic and foreign conditions of medical institutions, we proposed improvements for when remodeling becomes necessary and established criteria for safety-management in national inpatient isolation units for the care of patients in accordance with the domestic healthcare system.

Purpose: This study is for the facility eligibility and improvement evaluation analysis for the patient care environment of 7 facilities which has national inpatient isolation units. Methods: For the evaluation, first of all, the patient care environment of national inpatient isolation units are scrutinized by the checklist which is used on from 2014 with the 4 fields of criteria : architectural planning and layout, general requirement and condition for operating the negative pressured isolated patient room, HVAC system, and waste water discharging system. Finally, the evaluation results are compared with that of 2014. Results: The result shows that the average value of facility eligibility is 89.3 percent and which is 8.9 percent higher than the value before the MERS occurred. Implications: It is clear that facility remodeling of 7 institutions is being performed continuously, and the result of facility eligibility evaluation is reflected on design of a new 21 national inpatient isolation units those are going to be constructed from 2016. Therefore, it is expected that this study is used as a practical reference to establish the criteria of patient care environment management and safety management for both infectious disease outbreak and general service condition.

We consider the online scheduling problems of three and four machines under eligibility constraint. Respectively for the cases of three and four machines, we prove that AW algorithm has competitive ratios of $\frac{5}{2}$ and 3 which are shown to be optimal. Also, we show that the same results hold for the semi-online cases with prior knowledge of the total and the largest processing time.

In this paper, we survey the parallel machines scheduling problem with GoS eligibility constraints so as to minimize the makespan. Our survey covers off-line, online and semi-online scheduling problems. In the case of online scheduling, we only focus on online scheduling one by one. Hence we give an introduction to the problem and present important results of the problem.
