The geographically inequitable distribution of physicians has long posed a serious social problem in Japan. The government tackled this problem by establishing and managing Jichi Medical University (JMU) and regional quotas (RQs) for medical schools. JMU/RQs recruit local students who hope to work as physicians in rural areas, educate them for 6 years without tuition (JMU) or with scholarship (RQs), and after graduation, assign them to their home prefectures for 9 years, including 4–6 years of rural service. JMU/RQs entrants now (...) occupy 11.6% of all medical school entrants. While JMU/RQs have been shown to be highly effective in securing physicians for rural areas, ethical issues related to these policies have been raised, such as whether the government truly needs to implement these policies using tax money, and whether it is acceptable to limit the personal freedoms of the physicians. In this paper, we discuss these issues from the perspectives of social justice, utilitarianism, luck egalitarianism, liberty, medical professionalism and consistency with national health insurance and the Japanese Constitution. We conclude that JMU/RQs are necessary and ethically valid policies, and also propose some institutional improvements to better secure the integrity and maturity of these systems. (shrink)

Reinforcement learning has recently received much attention as a learning method for complicated systems, e.g., robot systems. It does not need prior knowledge and has higher capability of reactive and adaptive behaviors. However increase in dimensionality of the action-state space makes it diffcult to accomplish learning. The applicability of the existing reinforcement learning algorithms are effective for simple tasks with relatively small action-state space. In this paper, we propose a new reinforcement learning algorithm: “Q-learning with Dynamic Structuring of Exploration Space (...) Based on Genetic Algorithm ”. The algorithm is applicable to systems with high dimensional action and interior state spaces, for example a robot with many redundant degrees of freedom. To demonstrate the effectiveness of the proposed algorithm simulations of obstacle avoidance by a 50 links manipulator have been carried out. It is shown that effective behavior can be learned by using the proposed algorithm. (shrink)

Reinforcement learning is very effective for robot learning. Because it does not need priori knowledge and has higher capability of reactive and adaptive behaviors. In our previous works, we proposed new reinforcement learning algorithm: “Q-learning with Dynamic Structuring of Exploration Space Based on Genetic Algorithm (QDSEGA)”. It is designed for complicated systems with large action-state space like a robot with many redundant degrees of freedom. And we applied it to 50 link manipulator and effective behavior is acquired. However optimality and (...) fault tolerance of the proposed algorithm were not considered and to demonstrate effectiveness of the proposed algorithm other applications are necessary. Acquiring of locomotion patterns by a multi-legged robot is a very interesting problem. As it has many redundant degrees of freedom, application of usual reinforcement learning is difficult and an optimal locomotion has not been acquired using previous reinforcement learning algorithm. And the redundancy of the robot is effective to the fault tolerance and various locomotion patterns can be acquired for adapting the faults of the legs. In this paper, we applied QDSEGA to acquiring of locomotion pattern by the multi-legged robot and considered the optimality and fault tolerance. Effective behavior has been obtained by using our proposed algorithm. (shrink)

紀元前五世紀のインドで生まれた仏教。中国では布教に漢訳の経典が用いられたのに対し、日本は漢文のまま経典を輸入した。両国においてサンスクリットの原典は、ほとんど顧みられていない。中国は漢訳ならではの解釈 を生み出し、日本では特権的知識階級である僧が、意図的に読み替えた例もある。ブッダの本来の教えをサンスクリット原典から読み解き、日中両国における仏教受容の思惑・計算・誤解を明らかにする。.

サンスクリット原典の徹底的な精読を通じて明らかにする、『法華経』の教えの真意と現代的意義。.

Intervention studies on sedentary older adults have demonstrated that commencing physical exercise at an older age has a positive effect on brain structure. Although this suggests that older athletes with lifelong sports training have larger gray matter volume in some brain regions compared to age-matched non-athletes, evidence in the literature is scarce. Moreover, it remains unclear whether a larger GMV is associated with training intensity or period of training in life. To address these gaps in the literature, we compared regional (...) brain GMV between 24 older athletes and 24 age-matched non-athletes. The period of sports training and the current training time of the athletes were assessed. Both groups were evaluated for physical activity intensity as well as cognitive and motor performance. Although no group differences were noted in cognitive and motor performance, athletes reported higher physical activity intensity than non-athletes. Whole-brain structural analysis revealed a significantly larger GMV in several brain regions in athletes. Notably, the GMV of the precuneus in athletes was positively correlated with earlier commencement of sports training and training duration but was negatively correlated with current training time. Our findings demonstrate that early-commenced and continued sports training predicts structural maintenance of the precuneus in old age. Our results also suggest that excessive training time in old age may have a negative impact on the GMV of the precuneus; thereby delineating how the precuneus is associated with lifelong sports training in older athletes.

This study compared 30 older musicians and 30 age-matched non-musicians to investigate the association between lifelong musical instrument training and age-related cognitive decline and brain atrophy. Although previous research has demonstrated that young musicians have larger gray matter volume in the auditory-motor cortices and cerebellum than non-musicians, little is known about older musicians. Music imagery in young musicians is also known to share a neural underpinning [the supramarginal gyrus and cerebellum] with music performance. Thus, we hypothesized that older musicians would (...) show superiority to non-musicians in some of the abovementioned brain regions. Behavioral performance, GMV, and brain activity, including functional connectivity during melodic working memory tasks, were evaluated in both groups. Behaviorally, musicians exhibited a much higher tapping speed than non-musicians, and tapping speed was correlated with executive function in musicians. Structural analyses revealed larger GMVs in both sides of the cerebellum of musicians, and importantly, this was maintained until very old age. Task-related FC analyses revealed that musicians possessed greater cerebellar-hippocampal FC, which was correlated with tapping speed. Furthermore, musicians showed higher activation in the SMG during MWM tasks; this was correlated with earlier commencement of instrumental training. These results indicate advantages or heightened coupling in brain regions associated with music performance and imagery in musicians. We suggest that lifelong instrumental training highly predicts the structural maintenance of the cerebellum and related cognitive maintenance in old age. (shrink)

「近代の超克」から「近代の止揚」への“燎爛たる分裂”。西田幾多郎、三木清、戸坂潤の哲学を「個人‐市民‐大衆」形成論として捉える。.

Drawing on theories of institutional evolution, this article contends that despite the centrality of occupationally based social insurance in postwar Korea and Taiwan, the welfare state has in fact deepened considerably. The analysis is structured around three distinct eras of social policy reform in Korea and Taiwan: the developmental state, democratic transition, and postindustrialism. The authors contend that during each of these eras, the institutional purposes of social policy were altered to meet certain socioeconomic objectives. New institutional purposes were grafted (...) onto the prevailing social insurance model, changing the outcomes of social policy. The developmental state era was productivist in purpose, democratic reform during the 1980s reoriented social insurance toward universalist and redistributive principles, and the post-1997 era refocused social insurance to meet the imperatives of flexible labor markets, demographic shifts, and economic globalization.

Intelligent humanoid robots (IHRs) are becoming likely to be integrated into nursing practice. However, a proper integration of IHRs requires a detailed description and explanation of their essential capabilities, particularly regarding their competencies in replicating and portraying emotive functions such as empathy. Existing humanoid robots can exhibit rudimentary forms of empathy; as these machines slowly become commonplace in healthcare settings, they will be expected to express empathy as a natural function, rather than merely to portray artificial empathy as a replication (...) of human empathy. This article works with a twofold purpose: firstly, to consider the impact of artificial empathy in nursing and, secondly, to describe the influence of Affective Developmental Robotics (ADR) in anticipation of the empathic behaviour presented by artificial humanoid robots. The ADR has demonstrated that it can be one means by which humanoid nurse robots can achieve expressions of more relatable artificial empathy. This will be one of the vital models for intelligent humanoid robots currently in nurse robot development for the healthcare industry. A discussion of IHRs demonstrating artificial empathy is critical to nursing practice today, particularly in healthcare settings dense with technology. (shrink)

Die neuere Naturwissenschaft trat im 17. Jahrhundert zuerst als “Physik” auf. Man soll sich an die Gründung der modernen Dynamik von Galileo und Newton erinnern.Die methodisch-allgemeine Grundlegung dieser neuen Wissenschaft wird in der Cartesischen Philosophie am klarsten ausgedrückt.

This study investigated the circumstances and problems that departments of forensic medicine encounter with bereaved families regarding samples obtained from medico-legal autopsies. A questionnaire was posted to all 76 departments of forensic medicine performing medico-legal autopsies in Japan, and responses were received from 48 . Of the respondents, 12.8% had approached and communicated with bereaved families about collecting samples from the deceased person during an autopsy and the storage of the samples. In addition, 23.4% of these had informed families that (...) samples might be used in research. Eighteen departments had received enquiries and requests from families about the samples, with most requests concerning their return. The response to such requests varied according to the department. Few departments interacted with the bereaved families regarding the procedure for obtaining autopsy samples, and their methods for handling family concerns differed depending on the person within the department authorised to contact the family. Moreover, the procedures for engaging in such communication have long been unclear, and no legal or ethical consensus or agreement with the general public has been established. It is important for researchers to further discuss the correct way for forensic medicine departments to communicate with bereaved families. (shrink)

In this article we compare Fine’s theory of arbitrary objects with the theory of variables that Russell formulated in his Principles of Mathematics. We argue that Russell’s early theory of variables can be seen as a prefiguration of Fine’s theory of arbitrary objects. The main difference between Russell’s theory and Fine’s account lies in their account of dependence relations between variables. Fine develops a stable view of dependence between arbitrary objects, whereas no such view is presented in Principles of Mathematics. (...) We then sketch how Russell developed the notion of dependence between arbitrary objects in some of his subsequent works. (shrink)
