This paper presents a new and convenient process for determining the material plasticity parameters of metal materials through an indentation test conducted using a Rockwell testing machine and FE analysis. Identified parameters almost coincide with practical values. The proposed method can be used to evaluate the characteristics of materials on the order of micro to millimeters. First, the P-h curves of the indentation are determined by experiment. Second, FE analysis of the indentation test assuming plastic hardening behavior in power-law hardening material is specified by the stress-strain curve. The FE model consisted of the test piece material and the indenter with a spring element considered the elastic deformation of the measuring system. The material parameters can be identified based on the curve fit using the polynomial function consisting of material parameters. The best solution is determined by using the response surface methodology. For identification example using steel and cupper alloy, the estimation of the plastic and elastic properties are possible for practical use.

Water in the Earth has been transported from the oceans into its deep interior, where it forms hydrous deep mantle minerals. Wadsleyite [(Mg,Fe)2SiO4] has been considered as one of the most important host minerals incorporating this type of water as hydroxyl groups. To constrain the capacity of water in its structure and also to understand the effect of such water on its physical properties, it is essential to quantitatively determine the hydrogenʼs site and occupancy in the wadsleyite structure. Here we conduct a neutron time-of-flight single-crystal Laue diffraction study of it. Single crystals, which have size and quality suitable for this method, were successfully synthesized by a slow-cooling method at the relevant high pressure and temperature condition. The results unambiguously demonstrate a unique incorporation mechanism of hydrogen into the wadsleyite structure.

This paper examines how the economics of Marshall was pushed out of the mainstream of economics after his death.We firstly try to comfirm that the compatibility problem between competition and increasing returns was the main concern of Marshall from the early days of his career up to his Principles. Three new analytical tools he introduced into the Principles were intended to answer this problem. These are the distinction between internal and external economics, the period analysis, and the representative firm. The vision of the market as an organic system, we contend, is the key to understanding these three tools.Because economists at the early stage of institutionalization of the profession were eager to secure reliable analytical methods, the assessment of the economics of Marshall centered around the consistency of his analytical tools with the partial equilibrium method. Consequently, not enough attention was paid to the vision underlying his analytical tools. The same logic explains the gradual displacement of partial equilibrium method by general equilibrium method which started shortly after the assessment of Marshall by the Cambridge economists during the 1930s.

In Japan, during its era of Westernization from the mid-nineteenth century, political economy was introduced by way of a link in the chain of reception of Western enlightenment thought, which was characterized by its confidence in human reason and social progress. Afterwards, in line with national policy, political economy was rapidly institutionalized in Japan's higher education. Political economy was required to play a part in the authoritarian national order system. However, the vein of political economy as a component of enlightenment thought had never been eliminated. Such a political economy was observed in the non-main currents, beyond the so-called enlightenment period.This essay provides some examples from the latter half of the Meiji era to the Taisho era. Taguchi Ukichi and Keizaigaku Kyokai, Toda Kaichi and “Kyoto Keizaigaku”, and Takano Iwasaburo and Ohara Shakaimondai Kenkyujo, Osaka Rodo Gakko are all discussed from the viewpoint of the formation of scholars' groups. These scholars' groups spared no pains to emancipate political economy from the teachings of national policy and to locate it instead in civil life.

Banto Yamagata (1748-1821), a privileged Osaka merchant, spent his life during the period in which the Tokugawa regime entered a total structural crisis. As a rare rationalist who acquired universal reasoning from Confucian ideas, he proposed a system of economic thought (“keisei ron”) intended to promote a modern revival of the Confucian ideal politics “Jinsei” to overcome the crisis.He advanced a plan for an ideal Physiocratic peaceful state based on the principle of self-sufficiency (“jisan-jisoku”), challenging the currently dominant ideology of the mercantilist wealth-state, while excessively idealizing the existing order. He rationally grasped Japan's backwardness as compared to the mercantilist Western countries, and was seriously concerned that the mercantilist view of the national interest, which promoted outward expansion, would accelerate the external and internal crises.Thus we can see in his thinking, which emerged in the process of Japan's modernization, the possibility of rational Confucian economic thought.

Trans fatty acids are isomers of cis fatty acids. There are two main dietary sources of trans fatty acids- those derived from ruminant products such as milk, beef meat and those formed by the partial catalytic hydrogenation of vegetable and marine oils in the production of solid and liquid fats used in many industrially produced foods such as baked goods, frying fats and margarines. From epidemiological studies, increased coronary heart disease risk was associated with trans fatty acids. In addition, an excessive intake of trans fatty acids increased LDL-cholesterol level and decreased HDL-cholesterol. This paper reviews the outline of the trans fatty acids, the relation to disease and the intake situation of the trans fatty acids.

Rear projection is one of the most frequently used compositing techniques in Hollywood cinema from the 1930s to the late 1960s. Nevertheless, this technique has been hitherto underestimated. Of the scarce existing research, some studies have pointed out the economic advantages of it in terms of the studio system of the day, while others have examined it in the limited context of certain films or film directors. But such approaches have not paid sufficient attention to the fact that the many films had used the technique in spite of harsh criticism regarding the resultant image quality. This paper aims to clarify in part how the images created through rear projection were interpreted by the audiences of the time. The images were surely lacking in terms of the “reality” pursued by classical Hollywood cinema. However, the audiences were able to understand the mechanism of rear projection and experience its effects in a mode separate to that supposed by the classical Hollywood cinema. By analyzing a moving vehicle scene, I demonstrate how the gap created between foreground and background in the images re-arouses wonder in the audience, allowing them to enjoy the medium of cinema as a visceral attraction.

In the beginning of the thirteenth century, during the Shin-kokin period, waka poets followed classicism, reusing words and subjects from old poems. At the same time, they were in pursuit of atarashiki kokoro, or new content. New kokoro does not represent perfect newness that has never been composed; it represents content that overlaps with the classics. Moreover, the word atarashi has ambiguity; while new content is indeed ideal, novel subjects and how to use words are avoided. On the other hand, the word mezurashi means a kind of unexpectedness achieved by using old words in different contexts from past works. Mezurashi becomes especially significant in post-Shin-kokin waka. Nevertheless, since the fifteenth century, old poetry has begun to be ignored, and the focus has shifted to the kokoro of an individual poet. Atarashi, implying a newness that nobody has composed before, is emphasised and involves mezurashi. Such idealisation of novelty, which is regardless of differences from the old, brings the modern meaning of ‘originality’ to medieval waka. However, the classicism of waka never died until the modern era. Autonomous systems that identify differences from the classics as a norm have existed; thereby waka has acquired the extendibility and sustainability of composition.

Alberti’s impresa called the Winged Eye, carved in relief in his self-portrait plaque and medals, also drawn on some manuscripts from the end of 1420’s and the 1430’s, was described by Wind (1958) as the divine and awful God’s eye and is like a mystic Egyptian hieroglyph. Alberti was influenced by the discovery of Horapollo’s Hieroglyphica in 1419, and studied about hieroglyphs in the 1420s’ from Fracesco Filelfo, who was translating Pultarch’s Moralia that contains On the Worship of Isis and Osiris. However, it is also interpreted as a human eye since the Winged Eye is linked to the words “QUID TVM” from a poem by Virgil. In Alberti’s text of Anuli, the Winged Eye is a symbol of god and has human qualities such as prudence and providence. The Winged Eye is a Chimera-type image influenced by Egyptian and Greco-Roman cultures and is based on Egyptian hieroglyph’s eye and their amulets, as well as Roman coin reliefs of Octavianus in 38 BC, evil eyes and the Roman Winged Phallus amulets. The author suggests that when Alberti created the Winged Eye, he applied the Greek word “symbollon” which originally means “to throw together.”
