We have developed highly moisture-resistant optical adhesives for optical communication. These cyanogen-free and silane-modified adhesives are less allergenic and much safer for environments than conventional adhesives. These adhesives contain organic and inorganic hybrid structures and their median times to failure by deterioration are 11-132 times much longer than that of the conventional adhesive Epotek-353ND. Their adhesion characteristics are also good for other adherends. Furthermore, their high power resistivity and polarization maintaining property are better than those of the conventional adhesive Epotek-353ND.

Supervisory control is a control scheme to restrict the behavior of a discrete event system such that a given logical control specification is satisfied. Its unique feature is dealing with uncontrollable events that cannot be disabled using a controller, called the supervisor. In this article, we not only present basic theoretical results on supervisory control including the existence condition of a supervisor based on the controllability of languages and a method for synthesizing a maximally permissive supervisor but also discuss the effect of the existence of uncontrollable events and the issue of modeling the system and specification.

What is human ‘sociality’? It is possible that a robot/android-human theater can provide an answer to this question. In this article, we explain the history and background of a robot/android-human theater project (chapter 2), and from the results of analyzing the practice of making directions to actors and robots or androids, we discuss ethnography and conversation analysis in a field where artists and engineers work together (chapter 3). From the results of evaluating the practice of producing a theater, and from the impressions of the audience, we discuss engineering and cognitive science aspects of a robot/android-human theater (chapter 4). Finally, by considering the position of this project in the society, we discuss the significance of a robot/android-human theater in contemporary theatrical performance (chapter 5).

Microphone array signal processing is a framework for source localization, source enhancement and source separation with processing multichannel observations achieved using multiple microphones, which are difficult using a single microphone. In microphone array signal processing, the small time difference between channels is a very important cue to obtain spatial information. Therefore, a multichannel A-D converter has been conventionally essential for synchronized observation. On the other hand, if microphone array signal processing can be performed using asynchronous recording devices such as laptop PCs, voice recorders, or smart phones, which are easily available in daily life, it would enhance convenience and increase the number of possible applications markedly. In this review, focusing on a new trend of microphone array signal processing using asynchronously recording devices, we survey existing works and also introduce our approach.

The availability of genomic data resulting from rapid developments in gene sequencing technologies has accelerated the progress in genome epidemiological studies, which also contributes to the realization of genomebased disease-associated risk prediction as part of a personalized medical treatment. However, privacy concerns currently hinder the ubiquitous exploita-tion of personal genomic and clinical data. Accordingly, it is necessary to develop privacy-preserving methods that will allow the analysis of genomic and clinical data for genetic epidemiology and personalized medication as below. We give a broad overview of diverse risks and threts attached to the dissemination or publication of genetic data. As major privacy-enhancing technologies to reduce privacy risks, secure multiparty computation and differencial privacy are then introduced. We describe how these technologies preserve the privacy of genomic data when applied to genetic epidemiology and personalized medication.
