Objectives: The objective of this study was to identify seasonal changes of the physical activity in daily life of the elderly living in snowy regions. Subjects and Methods: Five healthy elderly individuals living in a snowy region were given pedometers for seven days every month in 2008, and analyses were performed on the research subjects' step counts, periods of activity, and personal journal contents. They received explanations of the research aims, methods, confidentiality, and free choice to participate. Results: Two of the subjects had high step counts and several periods of physical activity during spring to autumn, and were less active during winter. No seasonal changes were observed in the other three subjects. Within the journals maintained by the two individuals in whom seasonal changes were observed goals had been set for the number of steps to take, self-evaluations were present, and plans to achieve goals had been recorded. Conclusions: It was thought that a positive attitude toward self-management, behavioral characteristics affected changes in physical activity. It is difficult to maintain the amount of physical activity in winter. There is a need for places and opportunities that will lessen the effects of unfavorable winter weather conditions in snowy regions. Source

Objective: The aims of this study were to examine the number of missing teeth in the people of the Edo period (or number of remaining teeth) and to contribute to the 8020 movement proposed in Japan to help people retain 20 or more of their own teeth until the age of 80. Background: The study of dentition in ancient skeletal remains of our ancestors from multiple perspectives can yield information that can contribute to the study of physical anthropology and the leading edge of modern dental research. Materials and methods: The materials were 82 excavated individuals (52 males and 30 females) from 1603 to 1868 whose maxillas and mandibles were both examinable. The age and sex were estimated by anthropological methods, and the individuals were divided into five groups. The status of missing teeth was compared between groups, and a chi-square test was used to test significant differences between groups. The rates of tooth loss were examined in the maxillas and mandibles. Results: In the people of the Edo period, many teeth remained in good condition until early to late middle age. There were more remaining teeth in these individuals than in modern-day individuals. However, the Edo people clearly showed increased tooth loss with age. There were no differences in tooth loss by sex. The tooth type with a high rate of tooth loss was posterior teeth, but incisor loss also occurred with ageing. Mandibular canines were most likely to be remaining. Conclusion: The Edo people had more remaining teeth than modern-day society. This finding was unexpected. The notion that "people of long past ages lost more teeth more quickly" does not seem to apply to people in the Edo period in Japan. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

Engineers and researchers are paying more attention to reinforcement learning (RL) as a key technique for realizing adaptive and autonomous decentralized systems. In general, however, it is not easy to put RL into practical use. Our approach mainly deals with the problem of designing state and action spaces. Previously, an adaptive state space construction method which is called a "state space filter" and an adaptive action space construction method which is called "switching RL", have been proposed after the other space has been fixed. Then, we have reconstituted these two construction methods as one method by treating the former method and the latter method as a combined method for mimicking an infant's perceptual and motor developments and we have proposed a method which is based on introducing and referring to "entropy". In this paper, a computational experiment was conducted using a so-called "robot navigation problem" with three-dimensional continuous state space and two-dimensional continuous action space which is more complicated than a so-called "path planning problem". As a result, the validity of the proposed method has been confirmed. © 2012 ISAROB. Source

Reinforcement learning (RL) attracts much attention as a technique for realizing computational intelligence such as adaptive and autonomous decentralized systems. In general, however, it is not easy to put RL to practical use. This difficulty includes the problem of designing a suitable action space for an agent, i.e., satisfying two requirements in trade-off: (i) to keep the characteristics (or structure) of an original search space as much as possible in order to seek strategies that lie close to the optimal, and (ii) to reduce the search space as much as possible in order to expedite the learning process. In order to design a suitable action space adaptively, in this article, we propose a RL model with switching controllers based on Q-learning and an actor-critic to mimic the process of an infant's motor development in which gross motor skills develop before fine motor skills. Then a method for switching controllers is constructed by introducing and referring to the "entropy." Further, through computational experiments by using a path-planning problem with continuous action space, the validity and potential of the proposed method have been confirmed. © 2010 International Symposium on Artificial Life and Robotics (ISAROB).

The present study aimed to clarify the efficacy and issues of a confirmation system involving videobased self-evaluation regarding nursing students' skill in changing the sheets of bedridden patients. Skill acquisition status, students' ability to deliver accurate self-evaluations consistent with those of their teachers, and students' perceptions of the system were analyzed for 14 first-year students at N University. The system was positively perceived by the majority of students, and comparison of initial and repeat technique implementation after video-based confirmation revealed improved ability in all students. Particular improvements and a certain level of learning effect were observed for aspects of the nursing technique that demonstrated comparatively high degrees of consistency between student self-evaluations and teacher evaluations, specifically creases and slackness', consideration given to avoiding jolting the patient', position and balance', and making corners'. These aspects were also visually easy to perceive. Conversely, little improvement was observed for aspects for which there was low consistency between student and teacher evaluations, specifically observing and talking to patients' and body mechanics'. Further research is required regarding issues such as efficient confirmation methods and examining teaching materials and methods for more deliberately teaching these important points. Source
