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.

Reinforcement learning is a kind of unsupervised learning methods that an agent control rules from experiences acquired by interactions with environment. The eligibility is used to resolve the credit-assignment problem which is one of important problems in reinforcement learning, Conventional eligibilities such as the accumulating eligibility and the replacing eligibility are ineffective in use of rewards acquired in learning process, since on1y one executed action for a visited state is learned. In this paper, we propose a new eligibility, called the distributed 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 the proposed eligibility is applied to a cart-pole balancing problem, which shows the superiority of the proposed method to conventional methods in terms of learning speed.

When an individual needs to prove eligibility, it is sufficient to know whether or not s/he meets the eligibility, but any existing method inevitably exposes the identity of the owner or unnecessary additional information in the process of providing personal information. In this paper, among the immutable items of personal information such as gender, date of birth, and place of birth, we propose a method in which the owner provides only essential item(s) to the eligibility verifier with each iterm marked on one option among multiple choices. In this way, the eligibility verifier can access the combination of items stored in the blockchain with the consent of the information owner, and can safely store the access history by requesting recording in the blockchain again. In the proposed method, the user does not worry about his/her identity being revealed or his/her personal information being overly exposed, and the eligibility verifier can check only necessary items and search later records without separately storing the records.

With increase of Korean economy scale and globalization, permanent alien residents in Korea are increasing day by day. Living in Korea, they maintain their original nationalities, but their life in Korea is greatly affected by political decision made by Korea. It has been taken for granted that foreigners's suffrage were not recognized due to national sovereignty. The claim that foreigners should not be allowed to participate in government has constantly been met with counterargument on the basis of instability of sovereignty principle, trends of advanced countries, intrinsic differences between federal and regional governments, or actual state of foreigners. It is unreasonable to deal with foreigners' suffrage and eligibility for election differently in that the current public offices election law does not allow foreigners to be eligible for election without any special reason while allowing foreigners to vote in the local election. It is discrimination against foreigners not to allow foreigners to be eligible for election when there is no rationale to differently deal with foreigners' suffrage and eligibility for election. This paper deals with constitutional argument regarding foreigners' electoral eligibility, takes a look at legislative cases of Japanese and European countries, and examines possibilities of including foreigners' eligibility for election in our public offices election law.

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.
