概要. 本論文では,平山が提案した有限区間積分に対する数値積分法 —本論文では「超函数法」と呼ぶ —について解析を行う.超函数法では,問題とする積分を閉積分路上の複素積分に変換して,周期関数に対して性能の良い台形公式で近似計算する.数値実験により,超函数法は積分区間端点の特異性が強い積分に対して有効であることがわかる.また,超函数法と佐藤超函数論との関係についても触れる.

In light of the recent pandemic, favipiravir (Avigan®), a purine nucleic acid analog and antiviral agent approved for use in influenza in Japan, is being studied for the treatment of coronavirus disease 2019 (COVID-19). Increase in blood uric acid level is a frequent side effect of favipiravir. Here, we discussed the mechanism of blood uric acid elevation during favipiravir treatment. Favipiravir is metabolized to an inactive metabolite M1 by aldehyde oxidase and xanthine oxidase, and excreted into urine. In the kidney, uric acid handling is regulated by the balance of reabsorption and tubular secretion in the proximal tubules. Favipiravir and M1 act as moderate inhibitors of organic anion transporter 1 and 3 (OAT1 and OAT3), which are involved in uric acid excretion in the kidney. In addition, M1 enhances uric acid reuptake via urate transporter 1 (URAT1) in the renal proximal tubules. Thus, favipiravir is thought to decrease uric acid excretion into urine, resulting in elevation of uric acid levels in blood. Elevated uric acid levels were returned to normal after discontinuation of favipiravir, and favipiravir is not used for long periods of time for the treatment of viral infection. Thus, the effect on blood uric acid levels was subclinical in most studies. Nevertheless, the adverse effect of favipiravir might be clinically important in patients with a history of gout, hyperuricemia, kidney function impairment (in which blood concentration of M1 increases), and where there is concomitant use of other drugs affecting blood uric acid elevation.

Recent small-angle X-ray scattering (SAXS) for biological macromolecules (BioSAXS) is generally combined with size-exclusion chromatography (SEC-SAXS) at synchrotron facilities worldwide. For SEC-SAXS analysis, the final scattering profile for the target molecule is calculated from a large volume of continuously collected data. It would be ideal to automate this process; however, several complex problems exist regarding data measurement and analysis that have prevented automation. Here, we developed the analytical software MOLASS (Matrix Optimization with Low-rank factorization for Automated analysis of SEC-SAXS) to automatically calculate the final scattering profiles for solution structure analysis of target molecules. In this paper, the strategies for automatic analysis of SEC-SAXS data are described, including correction of baseline-drift using a low percentile method, optimization of peak decompositions composed of multiple scattering components using modified Gaussian fitting against the chromatogram, and rank determination for extrapolation to infinite dilution. In order to easily calculate each scattering component, the Moore-Penrose pseudo-inverse matrix is adopted as a basic calculation. Furthermore, this analysis method, in combination with UV–visible spectroscopy, led to better results in terms of accuracy in peak decomposition. Therefore, MOLASS will be able to smoothly suggest to users an accurate scattering profile for the subsequent structural analysis.

Although self-disclosure after a negative experience may be good for our adjustment, we also feel hesitant to do so. This study investigated the relationship between self-esteem and hesitancy to disclose negative information about one's self. One hundred and fifty-five undergraduates imagined self-disclosure to a friend of high or low intimacy. They then answered a questionnaire concerning hesitancy to self-disclose negative information to friends, as well as expected negative consequences of such self disclosure. Main results were: (1) Low intimacy strongly affected the hesitancy. (2) Factor analysis of the negative consequences found three factors: interpersonal and intra-personal negative-effect, and no positive expectation. (3) Hesitancy of high self-esteem students was most affected by the interpersonal factor. Impression management may be the reason. (4) On the other hand, low students tended to feel hurt after negative self-disclosure. Theirs was affected by the intra-personal and no positive expectation factors. Defensiveness may be the reason. The results were discussed from the viewpoint of adjustment when people have had a negative experience.

Conventional research on Kamakura-Fu (鎌倉府), which ruled the ten eastern provinces of the Kanto region during the Muromachi period, has tended to concentrate more on its relationship with the Muromachi Bakufu in Kyoto and less on what kind of power structure supported it and how this government controlled the various classes in the Kanto area. The present paper starts out to consider Kamakura-Fu's power structure and its control over the Kanto Plain, especially the power base of the Kamakura Kubo (鎌倉公方). Then, the author switches attention to the Hoko-shu (奉公衆) itself, which formed the military and political base of the Kamakura Kubo's ruling power ; and together with identifying that group of attendants from existing documents, he summarizes the Hoko-shu's conditions of existence and its organizational process. Concerning the Hoko-shu's conditions of existence, from the historical source entitled Kamakura Nenchu Gyoji (鎌倉年中行事), describing yearly events and ceremonies in that administrative town, we find three statuses within the Hoko-shu, namely 1)the Hyojo-shu (評定衆), 2)the Hikitsuke-shu (引付衆) and 3)other members. We see clear status discrimination toward those "other members" excluded from (or positioned below) statuses 1) and 2). Also, as the Hoko-shu formed a rotation system for guarding the Kubo's palace (gosho 御所), there were also members located (or living) in the provinces. The author was able to identify from the available sources 74 members of the Kamakura-Fu Hoko-shu. Their names and conditions of membership may be summarized as follows : A)The Ashikaga clan families including the Kira (吉良), Shibukawa (渋川), Isshiki (一色), Imagawa (今川), Kako (加子) and Hatakeyama (畠山). B)The original Ashikaga family vassals including the Uesugi (上杉), Ko (高), Kido (木戸), Noda (野田), Teraoka (寺岡), Kajiwara (梶原), Ebina (海老名), Shidara (設楽) and Yanada (簗田). C)Traditional Kamakura based bureaucrats including the Nikaido (二階堂), Nagai (長井), and Machino (町野). All of the families included in A, B and C served the Kamakura Kubo from the inception of Kamakura-Fu ; and during the era of Kubo Motouji (1349-67), the B group of Ashikaga vassals formed the dominant power group of the Hoko-shu. However, beginning from the era of Kubo Ujimitsu (1367-98) the Kamakura Kubo more and more included in the Hoko-shu many provincial bigmen (kokujin 国人) throughout the Kanto Plain. And so, when Mitsukane became Kubo (1398-1409), the number of Hoko-shu members had greatly increased, and their main source of power had shifted to a new group (D) made up of these same Kanto Plain kokujin. These included the likes of the Ohmori (大森) of Suruga, the Honma (本間) and Miura (三浦) of Sagami, the Edo (江戸) of Musashi, the Satomi (里見), Yamana (山名), Nawa (那波) and Takayama (高山) of Kozuke, the Sano (佐野) of Shimotsuke, the Shishido (宍戸), Tsukuba (筑波) and Oda (小田) of Hitachi and the Unagami (海上), Indo (印東) and Ryugasaki (龍崎) of Shimousa. During Mitsukane's reign such families as the Shishido and Unagami even appear in the elite corps of Kubo palace functionaries (gosho bugyo 御所奉行). As a result of their personal hold over these Kanto Plain kokujin, the Kamakura Kubos were able to expand quite successfully their own direct military bases.

This study focuses on the characteristics of the welfare regime of Japan after the second world war with the aim of forecasting its future. This study has found one of the major features of the welfare regime of Japan in its strong demand on families to be financially and physically independent. The risks the Japanese families had been forced to take by themselves, however, reduced to some extent by the governmental policies I call "communalization" or "kyodotaika."

The purpose of this study is to investigate consumer attitudes towards shopping in Japan. Factor analyses of data by 1,286 nonprobability online panels in a Web survey (in 2014) confirmed a hypothesized two-factor structure (the hedonic and utilitarian), but although the hedonic subscale had enough internal consistency, the utilitarian subscale had relatively low internal consistency. The correlations of the scores on consumer attitudes towards shopping with other measures, such as bargain orientation, impulsive buying tendency, and frugality, provided support for the criterion validity of each subscale. In many cases, these relationships were not affected by variables such as gender, life stage, and household income. Implications for the two-dimensional model of Japanese consumer attitudes towards shopping are discussed.

Two closely related species, Spiranthes sinensis and S. australis (Orchidaceae), have often been distinguished based on the presence or absence of hairs in their inflorescence and on the stems and ovaries: the stems and ovaries of S. australis are generally pubescent, whereas those of S. sinensis are reported to be glabrous. Although S. australis has not been documented to occur in Taiwan, we found a population of Spiranthes with slightly pubescent stems and ovaries at Tahanshan, southern Taiwan. Because the slightly pubescent plants may represent an undocumented extension of the distribution of S. australis, we attempted to identity the slightly pubescent plants by sequencing the ITS and trnL–F intergenic spacer regions. We also compared the lip and column morphology, which have diagnostic characteristics in Spiranthes, and the molecular and morphological data from S. australis, S. sinensis, their close relative, S. hongkongensis, and the unknown plants. The molecular analysis revealed the slightly pubescent plants to be heterozygous for the ITS sequences from S. australis and S. sinensis or from S. hongkongensis and S. sinensis, whereas the trnL–F intergenic spacer region was identical to that of S. sinensis. While we could not completely exclude the possibility that the unknown plants were hybrids between S. hongkongensis and S. sinensis based on the molecular data, we concluded that they were hybrids between the pubescent S. australis and the glabrous S. sinensis (Taiwan type) based on the lip and column morphology.

路面電車郊外とは,19世紀末に米国で展開した路面電車沿線に開発された郊外住宅地のことを指す。日本の地方都市における路面電車郊外像を探るべく,10の事例報告を通して類型化し,郊外住宅地の概念にどう位置づけられるか考察した。人口変動に伴う宅地化圧力と都市計画の実施状況を軸に以下の類型を見出した。人ロポテンシャルの高い都市では典型的な路面電車郊外が形成されたが,それ以外の都市では土地区画整理を計画したが連続的な宅地形成には至らず,都市計画事業を実現できず宅地化の萌芽に留まる例もあった。日本の路面電車郊外は自発性を含み,理念先行ではなく都市のポテンシャルに即して形成された郊外住宅地であると位置づけられる。

The recent emerging 'Net Right-Wing' became an important variable in the new trend of conservative swing and hate speech in both Japan and South Korea. This study analyzed “2Channel (rebranded as“5Channel”in October 2017)1)” and “ILBE” bulletin boards, which have recently created a threatening and hostile atmosphere in both countries. The results of the study show that at the root of conservative swing and hate speech lies the frustration of Japan's post-war democracy and of Korea's 1987 system.
