In recent years, application of Social Networking Services (SNS) and Blogs are growing as new communication tools on the Internet. Several large-scale SNS sites are prospering; meanwhile, many sites with relatively small scale are offering services. Such small-scale SNSs realize small-group isolated type of communication while neither mixi nor MySpace can do that. However, the studies on SNS are almost about particular large-scale SNSs and cannot analyze whether their results apply for general features or for special characteristics on the SNSs. From the point of view of comparison analysis on SNS, comparison with just several types of those cannot reach a statistically significant level. We analyze many SNS sites with the aim of classifying them by using some approaches. Our paper classifies 50,000 sites for small-scale SNSs and gives their features from the points of network structure, patterns of communication, and growth rate of SNS. The result of analysis for network structure shows that many SNS sites have small-world attribute with short path lengths and high coefficients of their cluster. Distribution of degrees of the SNS sites is close to power law. This result indicates the small-scale SNS sites raise the percentage of users with many friends than mixi. According to the analysis of their coefficients of assortativity, those SNS sites have negative values of assortativity, and that means users with high degree tend to connect users with small degree. Next, we analyze the patterns of user communication. A friend network of SNS is explicit while users' communication behaviors are defined as an implicit network. What kind of relationships do these networks have? To address this question, we obtain some characteristics of users' communication structure and activation patterns of users on the SNS sites. By using new indexes, friend aggregation rate and friend coverage rate, we show that SNS sites with high value of friend coverage rate activate diary postings and their comments. Besides, they become activated when hub users with high degree do not behave actively on the sites with high value of friend aggregation rate and high value of friend coverage rate. On the other hand, activation emerges when hub users behave actively on the sites with low value of friend aggregation rate and high value of friend coverage rate. Finally, we observe SNS sites which are increasing the number of users considerably, from the viewpoint of network structure, and extract characteristics of high growth SNS sites. As a result of discrimination on the basis of the decision tree analysis, we can recognize the high growth SNS sites with a high degree of accuracy. Besides, this approach suggests mixi and the other small-scale SNS sites have different character trait.

In participatory design, not only the designer, but other people such as end users participate in the process of designing to satisfy as many people as possible with the final product. The problem is, however, that interaction among people does not necessarily lead to good results. In our project we aim to make a design that reflects many people's intentions without interaction among them. We use rich text data from the web and computationally analyze the data to extract the intentions of people concerning the design. In this paper, we propose what data to use and how to analyze the data from a cognitive linguistic point of view. The points are that (i) we should use texts which are written spontaneously (such as those found in micro-blogs) and (ii) we should analyze the tense markers and epistemic modalities of the texts to extract intentions. We also introduce in the paper our workshop held at a library in an art university. In this workshop, we have visualized the intentions of students on digital maps.

従来の憲法学習の多くは,憲法の三大原則を教え込んでしまう内容主義に陥っている。そのため,子どもたちになぜ憲法が必要なのか,という疑問を持たせることなく,受動的に憲法を受け入れさせてしまう。そして何よりも「憲法とは何か」という本質的な理解をさせることができない。初等教育における憲法学習の目的は憲法の内容を教えることではなく,民主主義国家の中での憲法の役割がわかるようにすることであると考える。民主主義国家における憲法の役割とは,国民の人権を保障するために政治に縛りをかけることである(憲法の制限規範性)。そしてこの政治に対する制限規範としての憲法の役割を理解させることのできる授業開発をすることが本研究の目的である。

The Web is perhaps the most complex system that we know today. Its massive scale, complex dynamism, open richness, and social character mean that it may be more profitable to study it by using tools and concepts appropriate for understanding nervous systems, organisms, ecosystems and society, rather than approaches more traditionally employed to study engineering technology. Simultaneously, the scientists trying to understand this wide array of complex natural systems may have much to gain by considering the emerging study of the Web. In this paper, taking examples from our recent studies on the Web, we concretely discuss the relevance of the Web as a large model, as opposed to small models often used in physics or biology, for understanding living systems. An idea is forwarded of a default mode network that introduces autonomy, evolvability and homeostasis into the Web. For example, we argue for the existence of two modes of the states in Twitter; the excitation and baseline. The Web turns out to be an excitable media similar to a brain or certain kinds of chemical systems. R. Ashby's laws of requisite variety is also revisited to study its relevance in the light of controlling complex systems.

In the present study, amenity effect on human psychology as affected by ornamental foliage plants used as a screen was analyzed by means of electroencephalogram (EEG) and semantic differential technique.The experiments were carried out in a room at Ehime University in November and December of 1997. The following three conditions concerning the arrangement of ornamental foliage plants or screens around the subject were rated by eleven students.(a) a screen on each side of the subject(b) a screen on the one side and three ornamental foliage plants on the other side of the subject(c) three ornamental foliage plants on each side of the subjectElectroencephalogram of each student were measured in the room. Ratio of alpha wave to beta wave was calculated as an index expressing the degree of amenity. As for semantic differential technique, factor analysis was performed based on nineteen SD scales.Higher ratio of alpha wave to beta wave was observed in the condition (c). Two factors were extracted by the factor analysis. The factor scores of the condition (b) and the condition (c) were higher than the factor score of the condition (a). These results indicated the amenity effect on human psychology by plants.

In this study, three experiments were performed in order to investigate the effect of ornamental foliage plants on visual fatigue caused by visual display terminal operation. Visual fatigue was evaluated as critical flicker fusion frequency (CFF). Four students served as subjects in each experiment.The experiment (1) was carried out to examine the reduction of visual fatigue by viewing plants during visual display terminal operation. As the results, the CFF of the subjects in case of viewing plants was higher than that in case of viewing no plant. Especially, the difference of the CFF of the subject A was 9.3%.The experiment (2) was carried out to examine the recovery of visual fatigue by viewing plants after visual display terminal operation. As the results, the CFF of the three subjects except A increased in case of viewing plants and decreased in case of viewing no plant. The differences of the CFF of the subjects B and D were 4.6% and 3.6% respectively.The experiment (3) was carried out to determine whether difference in kinds of plants could bring about difference of the recovery of visual fatigue. As the results, average of the CFF of the subjects in case of viewing Schefflera arboricola “Hong Kong”, Cupressus macrocarpa “Gold Crest” and no plant decreased by 2.7%, 3.1% and 6.0% respectively, while average of the CFF of the subjects in case of viewing Dracaena fragrans “Massangeana” showed an increase of 0.6%.

人間は顔に対する認識能力が優れているため、現実の顔だけでなく顔イラストに対しても、その個性を認識し、描かれている表情を感じ取ることが出来る。本研究では、イラストで描かれた顔に対する人間の評価を元にして表情を定量的にモデル化し、それを任意の顔イラストに適用することで、元の顔の特徴を保持したまま表情のみを変化させられるシステムを構築した。

Alfred Tarski says that his definition of truth is in harmony with the postulates of physicalism. What Tarski means by 'physicalism, ' however, has not been understood well. In this paper the author tries to make it clear what Tarski's physicalism in semantics is. First, the author examines Hartry Field's well-known article 'Tarski's Theory of Truth, ' in which he contends that although Tarski's philosophical purpose in the theory of truth is to pursue physicalism, Tarski fails to do so. There Field suggests his understanding of physicalism as the basis of his contention. According to Field, physicalistic semantics ought to explain the causal connection between language and (extralinguistic) reality. Such an explanation demanded by Field is something which one may naturally expect from physicalistic semantics. But the problem is : Is it also what Tarski demands of physicalistic semantics ? Second, in order to solve the problem, the author investigates Tarski's two methods of introducing the concept of truth, namely, the method of definition and the axiomatic method. Tarski regards the former as physicalistic, the latter non-physicalistic. When this distinction is made, whether or not a method can explain the causal connection between language and reality is not used as the criterion by Tarski. According to Tarski, that a method does not contain any special theories of truth is the criterion for the method to be physicalistic. Accordingly, the axiomatic method is judged non-physicalistic because it characterizes the properties of the concept of truth by its own special axioms. From the physicalistic point of view, the concept of truth does not need to be explained at all, but only to be defined. This is Tarski's physicalistic theory of truth. Therefore the author concludes that Field's physicalism is not the same as Tarski's and that Tarski succeeds in pursuing his own version of physicalism.

“The standard method for the evaluation of acute toxicity of pesticides to fish” and “A method for the evaluation of acute toxicity of pesticides to daphnids” were established to give 48h TLm values for carp and 3h TLm values for Daphnia pulex or Moina macrocopa. With these and some modified methods, acute toxicity of all the already registered pesticides to carp and daphnids were evaluated, and factors influencing the toxicity of pesticides or sensitivity of test organisms to pesticides were investigated. The results are summarized as follows: (1) Rotenone and organochlorine insecticides, organomercurial, organotin, dimethyl dithiocarbamate and phthalimide fungicides, dinitrophenol and pentachlorphenol herbicides have high toxicity to carp, while organophosphorus and phenylcarbamate insecticides are extremely toxic to daphnids. (2) In general, emulsifiable concentrates, technical products, wettable powders, dust and granules are toxic to carp, in this order. (3) The majority of pesticides are more toxic to carp and daphnids at higher temperatures, but some, including folpet and DDT, are less toxic to carp and daphnids, respectively, at higher temperatures. (4) The majority of pesticides are less toxic at higher pH. (5) No apparent synergism or antagonism is observed to occur between 6 pairs of organophosphorus and phenyl carbamate insecticides with carp. (6) No remarkable change in sensitivity of carp is observed with growth to 6 pesticides, including organophosphorus insecticides and pentachlorphenol herbicide, although sensitivity to endosulfan insecticide is extremely high at earlier developmental stages after floating. (7) Dietary pesticides are in general less toxic to carp than pesticides in bath exposure systems. In addition, sensitivity of other aquatic organisms to pesticides was evaluated by the recently developed method. Results are summarized as follows: (1) Gold fish, tanago; Rhodeus moriokae, dojo; Misgurnus anguillicaudatus, and medata; Oryzias latipes, have sensitivity similar to carp. (2) Larvae of dragonfly; Orthetrum albistylum speciosum, and mayfly; Cloëon dipterum, are found to have lower sensitivity than daphnids, but the correlations of TLm values among them are comparatively high. (3) The molluscean animals, Indoplanorbis exustus, Cipangopaludina chinensis malleata, Semisulcospira libertine and Physa acuta have low sensitivity to pesticides in general. (4) Tadpoles of Bufo bufo japonicas, Rana brevipoda and Rana catesbeiana have low sensitivity to pesticides in general.

本研究の目的は,ソーシャル・ネットワーキング・サービス(SNS)サイトにおけるコミュニケーション構造の推移に着目し,SNSのライフサイクルにある種の法則性を見出すことである。我々は,SNSにおけるコミュニケーションのされ方の移り変わりに着目し,コミュニケーション関係は固定的に維持されるのか,推移していくのか,コミュニケーション関係はフレンドネットワークと近いのか,無関係なのかといったコミュニケーションの性質を表す因子を抽出している。これらの指標から,コミュニケーション構造の推移を明らかにし,その推移をライフサイクルとみなしSNSを分類している。分類したSNSのネットワーク構造や活性化の度合いを比較し,さらに特徴を分析している。その結果,現実の人間関係がベースとなるSNSは規模が小さく密なコミュニケーションがなされていることを確認している。また,ファンサイトのような対象物を中心としたSNSは,初期に開拓的であるものがより活性化することを確認している。
