This article presents a new model of contingent decision making in which utility theories (including nonlinear utility theories such as the rank-dependent utility theory) are often violated. In this model, called “Mental Ruler” theory, it is assumed that people construct a mental ruler to evaluate options for judgment and decision. A mental ruler is assumed to have two endpoints(reference points) like an ordinal physical ruler. It is assumed that a mental ruler is constructed on the support for a subjectively framed situation which is dependent on the focused situation. Contrary to the most of the utility theories and prospect theory, evaluation function is inverse S-shaped function, which is concave below and convex above a certain point between the endpoints of the support for the mental ruler. Firstly, In this article, a critique of the previous theories is presented, and secondly, the qualitative model of the mental ruler is proposed. Thirdly, a set-theoretic foundation and the mathematical representation of the model is presented. Lastly, experimental findings on contingent decision making are interpreted by the mental ruler theory, and the theoretical implication of the model is discussed.

A<sub>2</sub>B<sub>7</sub>型金属間化合物が主相である超格子水素吸蔵合金は、高いエネルギー密度や優れた自己放電を有しており、Ni-MH電池に使用されている。しかし結晶構造がAB<sub>2</sub>ユニットとAB<sub>5</sub>ユニットが積層した複雑な結晶構造を有しており、単相化しづらいことから結晶構造の同定が困難であった。今回、SPring-8の放射光X線を用いて測定し、リートベルト法で解析することにより、微小な相の比率や元素位置の同定を試みた。今回の測定結果では、Ndの一部をCeで置換した合金では、CeがAB<sub>2</sub>ユニットに存在しやすく、AB<sub>2</sub>相を収縮させ、水素吸蔵放出の可逆性が失われて電気化学容量の低下や劣化の促進を引き起こしたと考えられる。またNiの一部をAlで置換した合金では、AlがAB<sub>5</sub>ユニットに存在しやすく、AB<sub>5</sub>相を広げたため、より安定な水素吸蔵放出が可能になったと考えられる。

A pacemaker (PM) and an implantable cardioverter defibrillator (ICD) are devices that are inserted into the body to maintain regular heart rhythm in patients with serious heart rhythm problems. Among Japan's aging population, the number of patients requiring PM and ICD implantation has gradually and steadily increased. Therefore, a quantitative assessment of the future number of those patients is not only clinically, but also medical-economically and politically important. In this study, to develop a forecasting model for the number of patients requiring PM or ICD implantation, we analyzed past records of the number of PM and ICD implantation from 2006 to 2013 in Japan. Using a multiple regression analysis, we show the age and gender dependence of the number of PM and ICD implantation in each year, and propose a forecasting model based on age and gender composition rates of population. Moreover, as an application of our model, we estimate the future demand of PM and ICD devices in Japan.

This is the third section of a three-part discussion of the construction of Daigoji temple, ordered by Emperor Daigo in Engi 7 (907). As the final section of the article, this section clarifies the meaning of the temple construct at Kami-Daigo. The unusual feature of the Kami-Daigo temple complex is the parallel display of the exoteric Buddhist deity Yakushi with the esoteric Buddhist deities known as the Godaimyoo. This article focuses on this point and begins with an examination of the role and function of Yakushi and the Godaimyoo from the latter half of the 9th century onwards. This examination revealed that prior to the latter half of the 9th century, Yakushi and the Godaimyôô were both thought to be able to protect the country and ward off calamity. Thus it was deemed that they should be enshrined in the focal points of national protection, namely the Kokubunji temples and other such sites. Thus, the KamiDaigo temple complex commissioned by Emperor Daigo was fitted with not one but two central worship images that had powerful anti-calamity functions. This was not, however, a normal state of affairs. It is thought that this unusual situation was brought about by the domestic and international dangers and political unrest that occurred from the end of the 9th century through the beginning of the 10th century. Internally, unrest continued in the Kanto region, with the so-called "ôgoku no ran" riots occurring at the beginning of the 10th century proving a considerable threat to the imperial court. From offshore, pirates from Silla were sporadically raiding Japan. These extremely heightened political tensions provided the impetus for the creation of the Yakushi and Godaimyos images for Kami-Daigo. At first glance this combination of Yakushi and Godaimyôô appears to be a mixed gathering of different types. This "mélange" that supercedes the framework of exoteric/esoteric had not previously been seen in temples. However, this "mélange" appears to be the major characteristic of the imperially commissioned Daigoji, including both Kami-Daigo structures and the Shimo-Daigo structures. At the same time, this "mélange" could only have emerged because of the changes in national policy and culture that began in the early years of the 10th century. Indeed, the period changes are fully etched into this KamiDaigo temple complex.

Although shear wave elastography (SWE) has been used to indirectly measure passive force in muscle tissues, it is unknown whether SWE can be utilized to evaluate passive force in capsule tissues. This study investigated the relationship between the shear elastic modulus and passive force in posteroinferior shoulder capsules using SWE. Six posteroinferior shoulder capsules were dissected from six fresh-frozen cadavers; then, humeral head–capsule–glenoid specimens were created from each capsule. The humeral head and glenoid were each immobilized with clamps of a custom-built device. Passive force (0-400 g in 25 g increments) was applied to each capsule via a pulley system, and elasticity was measured simultaneously using SWE. Our data revealed that the relationship between the shear elastic modulus and passive capsule force was highly linear for all six tested capsules (p < 0.01). The mean (± standard deviation) coefficient of determination was 0.933 (±0.030; range 0.883 and 0.963). Our study demonstrated that SWE is a valid and useful method for indirectly and noninvasively evaluating the passive force of the posteroinferior shoulder capsule.

Diabetes mellitus (DM) is characterized by metabolic disorders and psychological deficits, including cognitive decline. Here, we investigated the effect of cordycepin on oxidative stress and protein expression in the brains of diabetic mice. Twenty-four mice were divided into four groups, one comprising untreated healthy mice (N); one comprising healthy mice treated with cordycepin (24 mg/kg body weight) (N+Cor); one comprising untreated DM mice; and one comprising DM mice treated with cordycepin (24 mg/kg body weight) (DM+Cor). After 14 days of treatment, cognitive behavior was assessed using the novel object recognition (NOR) test. The brain levels of oxidative stress markers (glutathione, catalase, and superoxide dismutase) were examined using the respective detection kits. Protein expression in brain tissues was assessed by liquid chromatography with tandem mass spectrometry (LC–MS/MS); the functions of the identified proteins were annotated by PANTHER, while major protein–protein interactions were assessed using STITCH. We found that cordycepin treatment significantly decreased body weight and food and water intake in the DM+Cor group compared with that in the DM group; however, no differences in blood glucose levels were found between the two groups. Cordycepin treatment significantly reversed cognitive decline in diabetic mice in the NOR test and ameliorated antioxidant defenses. Additionally, we identified ULK1 isoform 2, a protein associated with cognitive function via the activated AMPK and autophagic pathways, as being uniquely expressed in the DM+Cor group. Our findings provide novel insights into the cellular mechanisms underlying how cordycepin improves cognitive decline in diabetic mice.

This paper is the first of a three-part series that will discuss the historical and philosophical background of the creation of the Yakushi Triad in the Yakushidô Hall, KamiDaigo, Daigoji, Kyoto, created at the beginning of the 10th century during Japan's Heian period. This article first analyzes the formative expression of the Yakushi Nyorai figure that stands as the central figure of the Daigoji Yakushi Triad. As has been indicated by a number of previous studies of the subject, older elements can be discerned in parts of this figure's formative expression. These revivalist elements seen in the formative expression quote elements of the sculptural style prevalent in Japan from the end of the Nara period through the beginning of the Heian period. This article takes the discussion a step further, comparing the facial expression of the Daigoji Yakushi Nyorai figure with that of the Tôdaiji Amoghapasa figure created around the middle of the 8th century during the Nara period. This comparison clearly reveals the resemblance between the figures in terms of the three-dimensional expression of their eyes, eyebrows, noses and mouths. Sculptural style, namely the characteristics of three-dimensional expression, is individual for each different historical period. Yet, the Daigoji figure reveals the inclusion of past styles into the compositional elements of the facial expression. This quotation of a section of a specifically dated style cannot be seen in figures created before the Daigoji figures and can be considered a special characteristic of this sculpture's formative expression. This use of revivalist expression in the Daigoji figure can be considered to have been based on the participation of the priest Shôbô (832-909) in the construction of the KamiDaigo structures. This was because Shôbô had been the bettô, or manager in charge, of various temples where the restoration of Buddhist sculptures was being carried out. Thus he was a person deeply connected to Nara, and hence very familiar with formal styles of Nara period sculpture. However, when a temple was created by imperial command, the imperial court established a temporary organizational structure for its work. Hence the degree to which Shôbô would have participated in the determination of the sculptural style must be considered carefully. With the aim of getting a relative view of Shôbô's achievements, the second chapter of this paper aims to clarify the facts surrounding the organizational structure of Daigoji during this period. As an element of that study, the first section analyzes the Shingon sect priest Eri who is thought to have been active in the creation of Buddhist figures along with Shôbô. The section presents a critique of the historical documents available regarding Eri, and through analysis of the reliable documents, it can be shown that it was not Shôbô, but rather Eri who was the Buddhist priest entrusted with the organizational structure by order of the imperial court.
