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)

To investigate how bereaved families felt about the explanation received before and after forensic autopsies, the authors conducted a cross-sectional survey of the bereaved families whose next of kin underwent a forensic autopsy at the two Departments of Forensic Medicine and a few bereaved families of crime victims. Of 403 questionnaires sent, 126 families responded. Among 81.5% of the respondents who received an explanation from policemen before the autopsy, 78.8% felt that the quality of the explanation was poor or improper. (...) In Japan, the law has restricted disclosure of information from a forensic autopsy. Despite legal restrictions, 82% wanted to hear from the person who conducted the autopsy. However, police explained the results of autopsy to 65.2% of respondents. Among the families whose frustration and anger increased after autopsy, 86.4% had not been satisfied with the explanation before the autopsy. Additionally, 57.7% had not been informed on the autopsy findings at the time of the questionnaire when more than 2 years had passed after the autopsy. These results reminded us of the importance of an explanation before and shortly after a forensic autopsy for a better understanding and acceptance by bereaved families. (shrink)

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)

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)

Spatial metaphors of affect display remarkable consistencies across languages in mapping sensorimotor experiences onto emotional states, reflecting a great degree of similarity in how our bodies register affect. At the same time, however, affect is complex and there is more than a single possible mapping from vertical spatial concepts to affective states. Here we consider a previously unreported case of spatial metaphors mapping down onto desirable, and up undesirable emotional experiences in Mlabri, an Austroasiatic language of Thailand and Laos, making (...) a novel contribution to the study of metaphor and Cognitive Linguistics. Using first-hand corpus and elicitation data, we examine the metaphorical expressions: klol jur ‘heart going down’ and klol khɯn ‘heart going up’/klol kɔbɔ jur ‘heart not going down’. Though reflecting a metaphorical mapping opposite to the commonly reported happy is up metaphor, which is said to link to universal bodily correlates of emotion, the Mlabri metaphors are far from idiosyncratic. Rather, they are grounded in the bodily experience of positive low-arousal states, and in that reflect an emic view of ideal affect centered on contentment and tranquility. This underscores the complexity of bodily experience of affect, demonstrating that cultures draw on the available sensorimotor correlates of emotion in distinct ways. (shrink)

The purpose of this study was to clarify the minimum necessary educational content in the area of nursing ethics in a basic nursing education program, and the level of students’ mastery of this content, based on a Delphi study in both educational and clinical settings. A Delphi study was conducted in three rounds with faculty members who teach nursing ethics at all 158 four-year nursing universities in Japan as targeted panelists. In this study the opinions on nursing ethics of nursing (...) instructors responsible for hospital education at all 82 special functioning hospitals were reflected in the panelists’ opinions. Consensus was obtained on 41 items from a total of 63 items in 4 proposed frameworks. There were 20 items related to the Concept of nursing ethics, 7 items related to Ethical codes, 13 items related to Ethical issues and methods to resolve them, and 1 item related to Efforts and issues in practical and educational settings. Consensus as to desired level of mastery was reached on a total of 40 items. This agreed-upon level involved understanding of the concept for 22 items, the ability to explain the concept for 16 items, and the ability to act based on the concept for 2 items. (shrink)

We investigated the effects of everyday language exposure on the prediction of orthographic and phonological forms of a highly predictable word during listening comprehension. Native Japanese speakers in Tokyo (Experiment 1) and Berlin (Experiment 2) listened to sentences that contained a predictable word and viewed four objects. The critical object represented the target word (e.g., /sakana/;fish), an orthographic competitor (e.g., /tuno/;horn), a phonological competitor (e.g., /sakura/;cherry blossom), or an unrelated word (e.g., /hon/;book). The three other objects were distractors. The Tokyo (...) group fixated the target and the orthographic competitor over the unrelated objects before the target word was mentioned, suggesting that they pre-activated the orthographic form of the target word. The Berlin group showed a weaker bias toward the target than the Tokyo group, and they showed a tendency to fixate the orthographic competitor only when the orthographic similarity was very high. Thus, prediction effects were weaker in the Berlin group than in the Tokyo group. We found no evidence for the prediction of phonological information. The obtained group differences support probabilistic models of prediction, which regard the built-up language experience as a basis of prediction. (shrink)

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.

Understanding consciousness is a truly multidisciplinary project, attracting intense interest from researchers and theorists from diverse backgrounds. Thus, we now have computational scientists, neuroscientists, and philosophers all engaged in the same effort. This book draws together the work of leading researchers around the world, providing insights from these three general perspectives. The work is highlighted by a rare look at work being conducted by Japanese researchers.

We correct a mistake in the paper “Generalized periodicity and primitivity for words” [4] and justify the existence of regular languages all of whose roots are not even context-sensitive.

Schopenhauer’s theory of religion is mainly discussed in his ethics. Therefore, conventional studies often argue that Schopenhauer made an attempt to make a rational justification of religion through the process of recognising the reason for religion’s existence in its ethical values. However, his theory of religion contains other aspects which cannot be discussed soley in terms of the above view, for he not only observed subtle differences between religion and ethics but even considered that religion could go against ethics at (...) times. For this reason, we cannot simply say that Schopenhauer used ethics as a means to make a rational justification of religion. Rather, he viewed ethics as a standard for criticising religions, though he did not deny religion. He neither affirmed nor denied religion. Based on his ethics, he simply engaged in a philosophical analysis of a human activity called religion as he considered such an approach to be the appropriate one for a philosopher. On that account, what is important here is where in religion Schopenhauer saw the conditions for ethical values. From that point of view, this paper reinterprets his thought through descriptions in his major work, The World as Will and Representation, with an intention to offer a new reading of Schopenhauer’s theory of religion.
