     View Summary

    In the activity of creative bodily expression, we have structured “kansei expression media” which aims to create a new expression by facilitating image and movement generation of each performer and by weakly connecting their expressions. With utilizing the structured media, we have developed a model of bodily-expression activity. Close relation between media transformation and bodily expression has been clarified through the 3D-movement measurement and the subjective study in the fundamental study with the Shadow Media. We have confirmed that all the participants co-creatively make expressions in connection with media in the lesson practice or the workshop through the use of the developed activity model.

     View Summary

    We show a particular solution to solve the paradox in brain science and/or cognitive science, and propose the notion of phenomenal computation. In this perspective, the psychological time and space are explained as the process of individualization. The paradox of consciousness results from the mixture of two different categories, the wholeness and the locality. A neuron becomes a neuron making its own environment in which a neuron works. That is why a neuron involves the notion of a universe or wholeness in its own right. We propose the model of which a system becomes a system making its own environment in which a system works. In this model, the essential point is the form of incomplete wholeness. A system searches a formal universe incompletely, and then the environment can be made.
    Incomplete wholeness is formalized as a partially universal quantifier, and the formal environment called local semantics is formalized as a concept lattice. In this framework, a formal universe is also dynamically changed. A formal universe is defined as a triplet, two sets and the relation between them, and a local semantics is constructed as a lattice derived from a universe by using a partially universal quantifier. A system executes a computation in a generated local semantics, and the results of computation drive a change of the formal universe. This procedure is iterated, and then phenomenal computation proceeds. In this model, it is shown that the trade-off principle between universality and efficiency of computation found is programmable computation is weaken, and proper universal and proper efficient computation can be implemented. Syntactical computation and local semantics is replaced by the psychological time and space, and we estimate the dynamical relationship between them. This idea is also implemented as a cognitive experiment on memory of time and space. In a specific condition with reverse spectacles, we can obtain dynamical complementary relation between temporal memory and spatial memory.

     View Summary

    There has been almost no study made in which communication between each organ of a plant or between plants in a group was discussed from a view point of interrelationship. In order to investigate this problem, the process of BA fomation was researched by investigating whether synchronization phenomenon exists between individuals in environmental response and in morphogenesis or not. According to the plans and methods of this study which were reported in application form, the obtained results are following next 5 points.
    1. By making a long-term measurement of bio-electric potential changes (AC signals) of kapok leaves in a group, some leaves in seceded place showed same wave patterns. This phenomenon also happens when some leaves were excised. This shows that bio-electric potential changes in chaos. Furthermore, the correlation coefficient abates to about 2.5 when sound stimulation was given.
    2. By using a system which can make a long-term measurement of bio-electric potential (DC signals) changes, I have found that trees showing similar wave patterns form groups.
    3.A new measurement system which can measure patterns of changes on electric field self-organized around a root was developed. By this system, I investigated whether feeble electric field around a root changes or not by stimulating a stem or a leave with light, gavity, or obstacle. From experiments, we have found that electric field patterns are collapsed and re-organized in all cases. This suggests that electric field works as the autonomous interface between root and external environment, and roots create informations which were adjusted to environments on ground.
    4. By a system which can make a long-term measurement of motions of plant organs (leaves, roots, petals, and etc.), I have simultaneously measured rhythmic motions of a leaf and a root. I have found out that both root and leaf showed cooperative motions with period of about 2 [h]. Additionally, when two plants were placed adjacent to each other, both roots grew rhythmically with phase difference to not to collide int each other.
    5. Based on obtained results, I examined the communication of plants in emergence of BA,and I have indicated some knowledge on drafting informational BA.

     View Summary

    As the fundamental study on the biological information system in plant, the eddect of magnetic ot thermal stimulus on the regeneration phenomenon in callus and the surface biological potential behavior at each point in callus and in one leaf were investigated by the trial apparatus. Furthermore the relation between the intracellular potential detected by the capillay electrode and the leaf surface potential change detected by the Ag-Cl circular electrode having a diameter 5 mm was investigated by the another trial apparatus. Main results are as follows; (1) The shoor formation in the callus of carrot was accelerated under the magnetic stimulus. (2) The biological potential showed the cyclic ot rendom fluctuation after a few minutes in the case that the callus was wholly or partially stimulated by the magnetic stimulus. However the changes did not take place through all the area, but some part ot callus. Gurthermore the response parts in the callus changed with time. That is, the magnetic irritability of the callus depended with the location and the time. It could be considred above mentioned that magmetic stimulus induced or disturbed the spontaneous fluctuation in the callus, which was related to the regeneration. (3) the biological potential change of a learf showed the various patterns by the each magentic ot thermal stimulus points. Therefore the information path was rather complex. (4) The correlation was estimeted between the leaf surface potential and the inteacelluar potential changes. It couls be considered that the biological changes above mentioned were closely related to the recognition of the environment information in plant.

  • 植物的なコミニュケーションと情報場の設計

    1996  

     View Summary

     植物の外界認識やコミニュケーションに関する知見は動物とは異なった生物的な自律システムの設計原理を与える可能性がある。しかしながら、脳や神経系、感覚器官をもたない植物が様々に変化する環境を自身といかに関係付け、生長や形態形成に役立てているのか余り分かっていない。また、個体間のコミニュケーションの有無も定かではない。そこで本研究では、植物の生体電位(DC成分)やリズム運動に着目し、器官集団や個体集団における相互作用を情報システム論的な観点からしらべた。主な成果は以下の通りである。 1.エンドウの幼苗の茎先端部分を光刺激すると、刺激を受けた部分のみならず、主根先端部分においてもほぼ同周期のリズム運動が現われ、両者の間に位相関係が存在することを見出した。また、音刺激に対してもリズム運動が誘発されることを認めた。これらの結果は、環境情報が刺激箇所だけで局所的に処理されるのではなくて、相互引き込みにより植物体全体に共有されることを意味するものである。2.最大16本の幼苗を格子状に配列し生長挙動と生体電位変化を全自動計測できるシステムを構築した。本システムを用いて二三実験を行った結果、幼苗の生長速度は場所によって異なり一様ではないこと、さらに電位波形が類似するグループが複数存在することを明らかにした。また、このグループ形成と生長挙動との関係性について検討した。3.生体電位広域計測システムを用いて、野外における樹木集団のコミュニケーションについて調べた。その結果、自然林では同種、異種間において生体電位変化の相互引き込み的現象が起こり、時間経過とともに、樹木集団内にいくつものグループが動的、横断的に形成されることを見出した。4.以上の結果を基に、植物の個(部分)と集団(全体)との関係付けにおいて、情報の生成、共有がいかに行われるかを「場」と関連付けて考察した。
