Background Ethics committees and their system of research protocol peer-review are currently used worldwide. To ensure an international standard for research ethics and safety, however, data is needed on the quality and function of each nation's ethics committees. The purpose of this study was to describe the characteristics and developments of ethics committees established at medical schools and general hospitals in Japan. Methods This study consisted of four national surveys sent twice over a period of eight years to two separate (...) samples. The first target was the ethics committees of all 80 medical schools and the second target was all general hospitals with over 300 beds in Japan (n = 1457 in 1996 and n = 1491 in 2002). Instruments contained four sections: (1) committee structure, (2) frequency of annual meetings, (3) committee function, and (4) existence of a set of guidelines for the refusal of blood transfusion by Jehovah's Witnesses. Results Committee structure was overall interdisciplinary. Frequency of annual meetings increased significantly for both medical school and hospital ethics committees over the eight years. The primary activities for medical school and hospital ethics committees were research protocol reviews and policy making. Results also showed a significant increase in the use of ethical guidelines, particularly those related to the refusal of blood transfusion by Jehovah's Witnesses, among both medical school and hospital ethics committees. Conclusion Overall findings indicated a greater recognized degree of responsibilities and an increase in workload for Japanese ethics committees. (shrink)

Human interaction has two principle functions: building and maintaining relationships with others and exchanging information. The function of building and maintaining relationships with others relates to interpersonal coordination; this behavior pattern is expected to predict the outcome of social relationships, such as between therapists and patients. It is unclear, however, whether the exchange of information is associated with interpersonal coordination. In the present study, we tested a hypothesis of whether body movement synchrony occurs in a natural conversation and whether this (...) synchrony has a positive correlation with the degree of information exchange. Fifty participants were engaged in a conversation task; each had different roles in the conversation. We measured their body movements during this conversation using an optical motion capture system. Similar to methods that can be found in previous research, we calculated body movements and quantified their synchrony applying the methods previously reported that automatically quantified their body movements. Moreover, we determined the participants’ degree of information exchange concerning the conversation using a questionnaire. We observed that the body movement synchrony of pairs who talked with each other was significantly higher than that of pairs who did not talk with each other, and that this synchrony was positively associated with the degree of information exchange. These results suggest that body movement synchrony predicted information exchange. (shrink)

Compared to institutional and area-based ethics committees, little is known about the structure and activities performed by ethics committees at national medical organizations and societies. This five year follow-up study aimed to determine (1) the creation and function of ethics committees at medical organizations in Japan, and (2) their general strategies to deal with ethical problems. The study sample included the member societies of the Japanese Association of Medical Sciences (n=92 in 1998, n=96 in 2003). Instruments consisted of two sections: (...) (1) the structure, function and activities of ethics committees, and (2) the strategies for dealing with ethical problems. Response rates were 84.4% in 1998 and 64.4% in 2003. Findings showed a significant increase of ethics committees at medical organizations between 1998 (25.6%) and 2003 (50.0%). Members were mostly male, medical doctors in clinical or basic medicine, and members of the organization. The major functions of ethics committees were ethical reviews of research protocols, policy making and ethical reviews of manuscripts submitted for journal publication. Among organizations that did not have an ethics committee, a significant decrease was found in organizations that replied that they had never experienced an ethical problem which needed further investigation (p<0.01). Findings suggested an overall rise in awareness of the importance of ethical issues and also highlighted an increase in recognition of responsibility regarding ethical problems. (shrink)

To further develop three-dimensional (3D) applications, it is important to elucidate the negative effects of 3D applications on the human body and mind. Thus, this study investigated differences in the effects of visual fatigue on cognition and brain activity using visual and auditory tasks induced by watching a 1-h movie in two dimensions (2D) and 3D. Eighteen young men participated in this study. Two conditions were randomly performed for each participant on different days, namely, watching the 1-h movie on television (...) in 2D (control condition) and 3D (3D condition). Before and after watching the 1-h movie on television, critical flicker fusion frequency (CFF: an index of visual fatigue), and response accuracy and reaction time for the cognitive tasks were determined. Brain activity during the cognitive tasks was evaluated using a multi-channel near-infrared spectroscopy system. In contrast to the control condition, the decreased CFF, and the lengthened reaction time and the decreased activity around the right primary somatosensory cortex during Go/NoGo blocks in the visual task at post-viewing in the 3D condition were significant, with significant repeated measures correlations among them. Meanwhile, in the auditory task, the changes in cognitive performance and brain activity during the Go/NoGo blocks were not significant in the 3D condition. These results suggest that the failure or delay in the transmission of visual information to the primary somatosensory cortex due to visual fatigue induced by watching a 3D movie reduced the brain activity around the primary somatosensory cortex, resulting in poor cognitive performance for the visual task. This suggests that performing tasks that require visual information, such as running in the dark or driving a car, immediately after using a 3D application, may create unexpected risks in our lives. Thus, the findings of this study will help outlining precautions for the use of 3D applications. (shrink)

Cet article s’intéresse aux mutations de la famille japonaise au XXe siècle à travers les manga de Machiko Hasegawa (Sazae-san), première dessinatrice de bande dessinée au Japon, et de Kyoko Okazaki (La maison du bonheur et Au bord de la rivière), qui appartient à la génération actuelle. L’analyse comparée de plusieurs de leurs albums montre, notamment à travers les scènes de repas, la déstructuration de la famille japonaise d’après-guerre, dans un contexte d’industrialisation qui a poussé les Japonaises à délaisser en (...) partie le foyer familial pour travailler.

In Legends of the Samurai, Sato confronts both the history and the legend of the samurai, untangling the two to present an authentic picture of these legendary warriors. Through his masterful translations of original samurai tales, laws, dicta, reports, and arguments accompanied by insightful commentary, Hiroaki Sato chronicles the changing ethos of the Japanese warrior from the samurai's historical origins to his rise to political power. For this purpose, Sato has chosen to translate, wherever possible, writings closest in time to (...) the actual event. His translations are a testament to his mastery of the language for they flow with lively ease that one might not expect from accounts, many of which are ancient. Legends of the Samurai covers legends from mythological times to the early eighteenth century. Through this book Sato describes men accomplished in martial arts, warrior-commanders in battle, and samurai's own views of themselves. It ends with a famous modern retelling of a mass disembowelment in the mid-seventeenth century. (shrink)

The plasmodium of _Physarum polycephalum_ is a unicellular and multinuclear giant amoeba with computational abilities. The plasmodium has been widely used as a model organism in the field of bio-computing; however, its ability to perform computation related to its biological nature itself in the essential sense has not yet been fully realized. Therefore, in this study, we focused on the phenomenon in which a plasmodium trapped in a closed space surrounded by repellent substances escapes from the field by changing its (...) own behavior rules. We demonstrated that this phenomenon is bio-computationally important in that it may enable the implementation of biological characteristics in computing. (shrink)

Public satisfaction with policy process influences the legitimacy and acceptance of policies, and conditions the future political process, especially when contending ethical value judgments are involved. On the other hand, public involvement is required if effective policy is to be developed and accepted.

In 1997, after long social debates, the Japanese government enacted a law on organ transplantation from brain-dead bodies. Since 1993, on gene therapy, administrative agencies have issued a series of guidelines. This study seeks to elucidate when people became aware of the issues and when they formed their opinions on organ transplant and gene therapy. At the same time, it aims to examine at which point in time experts, those in university ethical committees and in academic societies, consider these technologies (...) became accepted among the public. A self-administered questionnaire was sent by mail to a stratified random sampling of 3000 people nationwide in Japan. Another questionnaire was sent both to the member societies of the Japanese Association of Medical Sciences and to the ethical committees of all the medical schools in Japan. Results of the surveys indicated that many of the public remained undecided on the desirability of organ transplant or gene therapy at the time of enactment of official guidelines. A substantial part of them formed their opinions in subsequent periods, especially around the time of first implementation and thereafter. Experts of the academic societies and of the university ethical committees regarded the time of implementation as an important factor in the acceptance of the technologies in society. Since many people formed their opinion during the period of technological implementation, communications efforts to facilitate public understanding of science and technology, as well as to advance practical discussion on policy alternatives in this period can play a key role in determining the fate of technological innovation and ethical debates in medicine.
