KM (Knowledge Management) systems have recently been adopted within the realm of enterprise management. On the other hand, data mining technology is widely acknowledged within Information systems' R&D Divisions. Specially, acquisition of meaningful information from Web usage data has become one of the most exciting eras. In this paper, we employ a Web based KM system and propose a framework for applying Web Usage Mining technology to KM data. As it turns out, task duration varies according to different user operations (...) such as referencing a table-of-contents page, down-loading a target file, and writing to a bulletin board. This in turn makes it possible to easily predict the purpose of the user's task. By taking these observations into account, we segmented access log data manually. These results were compared with results abstained by applying the constant interval method. Next, we obtained a segmentation rule of Web access logs by applying a machine-learning algorithm to manually segmented access logs as training data. Then, the newly obtained segmentation rule was compared with other known methods including the time interval method by evaluating their segmentation results in terms of recall and precision rates and it was shown that our rule attained the best results in both measures. Furthermore, the segmented data were fed to an association rule miner and the obtained association rules were utilized to modify the Web structure. (shrink)

The planet is experiencing a deep metamorphosis. The pressure that is being generated nowadays on the living can be felt in a human lifetime. The extreme speed of climate change and its impact on our ecosystem can no longer be ignored. When looking at the phenomenon of ecological resilience, we notice that after a disturbance, a shock on an ecosystem, like the burning of a forest, the resilient system rebuilds itself but not exactly as it was before, surprisingly new species (...) grow. In social systems, humans have the capacity to anticipate, adapt and invent new patterns of behaviours. In a world where everything is uncertain, moving, shifting, we are making an artistic proposal as an open dynamic system. We are developing two versions of the same HALO project to be presented on the sea and in public places. (shrink)

The sophisticated function of the central nervous system (CNS) is largely supported by proper interactions between neural cells and blood vessels. Accumulating evidence has demonstrated that neurons and glial cells support the formation of blood vessels, which in turn, act as migratory scaffolds for these cell types. Neural progenitors are also involved in the regulation of blood vessel formation. This mutual interaction between neural cells and blood vessels is elegantly controlled by several chemokines, growth factors, extracellular matrix, and adhesion molecules (...) such as integrins. Recent research has revealed that newly migrating cell types along blood vessels repel other preexisting migrating cell types, causing them to detach from the blood vessels. In this review, we discuss vascular formation and cell migration, particularly during development. Moreover, we discuss how the crosstalk between blood vessels and neurons and glial cells could be related to neurodevelopmental disorders. (shrink)

The form of higher plants is largely dependent upon cell division and expansion patterns. Taking a genetic approach, Takahashi et al.(1) have identified a regulatory molecule in Arabidopsis thaliana called DIMINUTO (DIM), which is involved in determining the degree and direction of plant cell expansion. Their extensive characterization of a dim mutant suggested a direct involvement of the DIM gene in regulating cell elongation, perhaps by modulating the expression of structural genes which determine the orientation and elasticity of the cell (...) wall.

新資料から、現代にも通ずる日本独自の豊かな死生観を探求した、江戸後期を代表する思想家としての新たな篤胤像を描き出す意欲作。.

儒教・仏教という知的伝統と、西洋哲学という新たな知が出会った明治。近代化と伝統の間で花開く新たな知の深層を明らかにする!

As I have pointed out in a series of papers, which appeared about fifteen years ago in the Revue de l'histoire des religions, there are numerous resemblances between the ancient myths of the Indo-Europeans, on the one hand, and those of Japan, on the other. These resemblances, relating both to the fundamental structures of the two mythological systems and to a number of curious details, constitute an assemblage which seems too conspicuous to be regarded as either accidental or the result (...) of a similitude of human mentalities, manifesting itself, so it seems, through the creation of a great many similar myths and legends throughout the length and breadth of the surface of our planet.

We proposed the Standards of Conducts to provide a general framework that will serve as the basis for guiding each biostatistician and stem cell researcher to formulate their personal standards, rather than as rules with which they are required to comply. Given the responsibility and characteristics of their work, they are expected to maintain independence and work autonomously as professionals. Each of the Standards of Conducts comprises a preamble, mission and values to uphold, Standards of Conducts, and background. When one (...) internalizes “self-formulated” standards, to make excuses for oneself would be akin to a self-betrayal; responsible actions can be anticipated. If one begins and continues to consider “who I am and what do I work for,” this will become their inner energy, and a source of motivation and pride to inspire oneself. In addition, this aspirational style might help citizens to recognize the autonomous stance of the professional body and that they share the same values. (shrink)

In nature, cells face a variety of stresses that cause physical damage to the plasma membrane and cell wall. It is well established that evolutionarily conserved cell cycle checkpoints monitor various cellular perturbations, including DNA damage and spindle misalignment. However, the ability of these cell cycle checkpoints to sense a damaged plasma membrane/cell wall is poorly understood. To the best of our knowledge, our recent paper described the first example of such a checkpoint, using budding yeast as a model. In (...) this review, we will discuss this important question as well as provide hypothetical explanations to be tested in the future. (shrink)

While much has been written about the uniquely Hawaiian take on the category “local” – usually in terms of resistance to colonization, the alternative or counterhegemonic – little has been written about “haole”, the trope that served to silhouette the “local” and has evolved in dialectical opposition to it. A term that emerged during the plantation era to represent working-class immigrant workers mostly from Asia, “local” is constructed by exclusion. It has evolved to represent solidarity against all “external forces” controlling (...) Hawai'i from without, such as land development, tourism and the military – all readily equated with haole, the visible sign of whiteness. The prevalence of the prescription “local vs. haole” in contemporary Hawai'i begs an inquiry into other interpretations that are being suppressed. This paper explores some suppressed histories, imaginings and subconscious aspects of identity in Hawai'i through the figure of the white person whose parents – and possibly great-great-great-grandparents – were born and raised in Hawai'i.

In this article I examine Lavoisier's collaboration with his wife in the translation of Kirwan's An essay on phlogiston into French (Essai sur le phlogistique, 1788). This translation is a kind of counter attack by the school of French scholars around Lavoisier. Mrs Lavoisier is generally considered only to have translated Kirwan's book, not to have refuted it. Through a detailed analysis of the translation, of her manuscripts, and of other documents of the period, I conclude that Mrs Lavoisier not (...) only actively attacked the doctrine of phlogiston in her translation, but in the notes and preface to it as well. In addition to her high-level knowledge of chemistry, her close scientific relationship with her husband should be noted. In the first three parts of the translation, the two shared the work between them, in order to convine the readers. A show that Mrs Lavoisier advocated the study of gases from the point of view of their motions, and that she always believed that her husband's theory would prevail. Moreover, Lavoisier assessed his wife's talent at its true value. (shrink)

This article extends the concept of symmetry to ethics. Using the case of canola in Canada, the authors argue that grades and standards simultaneously subject humans and nonhumans to rites of passage that test their "goodness. " Then, they further develop a tentative typology of standards. The authors argue that these standards allow something resembling the neoclassical market to be established, create the conditions for economic analysis, and allocate power among human actors.
