音は空気の疎密変化であり,疎密によって媒質の屈折率も変化するので,光を用いて屈折率を計測することで音を録ることができる.これは,マイクロホンの特性や音場への干渉が影響することのない非破壊非接触な計測を可能にし,また遠方から音情報を取得可能であるという利点も有するが,一方で,計測された信号の SN 比が悪いという課題がある.これに対し,筆者らは物理モデルを用いた信号処理を提案しており,SN 比の改善に取り組んでいる.本稿では,様々な光学的音響測定手法を概説した後,筆者らが提案する信号処理と,今後期待される応用について述べる.

This paper aims to study the creative process of collaborative improvisation, which has rarely been the subject of cognitive science research. The special focus is on how a dancer’s improvisational process is influenced by another dancer’s performance. Bat-tle performances of street dance are chosen as the target performances of this study and contrasted with solo performances, because in battle situations dancers have to generate their original expressions in a highly improvised manner. We conducted an experimental study, aiming to investigate both the cognitive process of dancers and the characteristic features of their dance performances. The three main results are as follows: 1) The generation frequency of new dance movements was not different be-tween solo and battle dance performances. 2) The generation process of a dancer’s new dance movements was influenced by another dancer’s performance. In the battle per-formances, dancers generated new dance movements by combining several movements that they had already acquired, while they generated new movements by only changing some parts of their acquired dance movements in the solo performances. 3) In the battle performances, as distinct from the solo dance performances, dancers generated their dance movements by adopting movements of another dancers and changing the structures of their movements. These features resulted in differences in the processes of generating new patterns.

The objective of this paper is to examine Gary Snyder's views on love in Regarding Wave with special attention to his attitudes toward nature and his scientific thinking.In Regarding Wave, Snyder tries to locate the element of love within the conversion of energy through biological imagination. He observes the behavior of the human race, and he holds females, in great esteem as the source of the energy. Snyder's idea of love is not based on the traditional concept of love in the Western world, but it is an extension of the act of eating. For him, his partner and family are an energy network that supplies him with vitality. Love is the most important process of exchanging energy which is not privileged to humankind. Accordingly, Snyder extends the identity of human beings into the roles of other life forms on earth.This idea is supported by his detailed understanding of the-natural world. There are some scientific theories behind his literary imagination; the first is quantum mechanics, the fundamental theory used by 20th-century physicists to describe atomic and subatomic phenomena. According to the quantum theory, the conversion of energy is caused by wave patterns in the natural world, so on many occasions, Snyder uses waves metaphorically in the poems both in their contents and in their forms. Even more important is thermodynamics, the branch of physics that studies the transfer of heat and the interconversion of heat and work in various physical processes. Snyder's imagination is also transferred from the external energy according to the first law of thermodynamics. Therefore, his creative activities are located in the working of nature, and his poems store wave like energy which is transmitted to his readers.Love is an essential part of the flow of his scientific energy and the idea that one organism is linked to another, and then another is the most important part of his thought project. Snyder locates human beings as merely a part of the totality of the environment rather than at the center of the world.
