Debris flow is composed of mixed-size gravel, and the grain size distribution and concentration of sediment strongly affects the flow behavior. To predict more accurate debris flows, we need a numerical model that considers mixed-size gravel and can describe sediment sorting. We propose a more accurate method for predicting mixed-size debris flow behavior, from torrents to alluvial fans. We combined a debris flow model that can describe sediment sorting with an integration model, and proposed an integrated model for mixed-size gravel. Applying this model, we simulated debris flow on a virtual watershed under different conditions of inflow sediment distribution. Our results showed that an integrated model for mixed-size gravel provide a more rational description of debris flow in torrents and alluvial fans than models of uniform-sized gravel.

The present study aimed to develop a short-form self-report measure to assess relaxation effects (S-MARE). Participants (N = 190) responded to a questionnaire comprised of 45 items assessing relaxation and non-relaxation based on the Relaxation Inventory (Crist et al., 1989). Exploratory factor analysis identified three factors: physiological tension, psychological relaxation, and anxiety. Each factor was related to 5 items and each had an acceptable Cronbach’s coefficient (α = .93, .94, and .85). S-MARE scores pre- and post- relaxation instruction were significantly correlated with the Emotional Relaxation Scale (Tokuda, 2011) (r = .446) and with State Anxiety (r = –.531) (N = 172). There was a significant correlation between the amplitude of the high frequency component of heart rate variability during relaxation instruction and physiological tension scores on the S-MARE (r = .456—.474, N = 24). These results confirmed the reliability and validity of the S-MARE in terms of physiological correlation with cardiac parasympathetic tone, suggesting that the S-MARE is a valid measure of relaxation effects.

Sweetpotato (Ipomoea batatas) cultivars grown in Japan are highly valued for their excellent sweetness, high quality, and good texture. The export volume of sweetpotato from Japan has been rising rapidly, with a 10-fold increase on a weight basis over the last 10 years. However, since sweetpotato is propagated vegetatively from storage roots, it is easy to cultivate and propagate this crop, prompting concerns that Japanese sweetpotato cultivars/lines are being exported overseas, cultivated without permission, or reimported. Therefore, a rapid and accurate cultivar identification methodology is needed. In this study, we comprehensively analyzed the insertion sites of Cl8 retrotransposon to develop a cultivar identification technique for the Japanese cultivars ‘Beniharuka’ and ‘Fukumurasaki’. These two cultivars were successfully distinguished from other cultivars using a minimum of two marker sets. Using the chromatographic printed array strip (C-PAS) method for DNA signal detection, ‘Beniharuka’ and ‘Fukumurasaki’ can be precisely identified using a single strip of chromatographic paper based on multiplex DNA signals derived from the amplicons of the Cl8 insertion sites. Since this method can detect DNA signals in only ~15 minutes, we expect that our method will facilitate rapid, reliable, and convenient cultivar discrimination for on-site inspection of sweetpotato.

本研究では、古代において国府と京を結んでいた七道駅路を中心として、古代物流ネットワークの形態解析と物流システムの移動利便性として移動距離や日数、運賃との関係について分析した。七道駅路ネットワークを構築した上で、本路・支路によって結ばれている国府の隣接グラフを構築した。そして、最小木と重複しない隣接グラフの辺は、地方と京をなるべく短い距離で結ぶように、放射・縦断方向に長い辺が構築されていることが明らかになった。七道駅路を用いた物流システムについて、運賃は距離と線形に比例する関係が見られ、往復日数の方が距離よりも運賃と比例関係が強いことが明らかになった。海上輸送は、陸上輸送と比べて、所要日数が少なく、運賃も大幅に低いことが明らかになった。このように、地形の起伏や広大な河川、海上輸送を含むかどうかが、移動に大きく影響していることが明らかになった。現在価値への換算すると、現代のトラック運賃と比べて、遠距離に行くほど差が広がっていることが明らかになった。このように、古代の物流においては、現代より日数、費用ともに大きくコストをかけて運ばれていたことが定量的に明らかになった。

Now that the Product Liability Law directly applies to pharmaceutical companies, their responsibility is much greater than before. Although the Product Liability Law does not directly apply to doctors and to pharmacists who are engaged in the preparation of medicines, they will indirectly but greatly be influenced by it as a result of the Product Liability Law being applied to the pharmaceutical companies.

Monazite in a granite pegmatite from Yamanoo, Sakuragawa, Ibaraki Prefecture, Japan has been examined in terms of U, Th, Pb, and rare earth element (REE) chemistry by electron microprobe analysis. This pegmatite occurs as a lenticular vein in the Kabasan granitic body. Oscillatory and sector zoning were observed by back-scattered electron images. An averaged empirical formula was (Ce0.286Nd0.180Sm0.104La0.077Y0.069Pr0.041Gd0.069Dy0.020Er0.004Th0.069U0.011Ca0.052)Σ0.982 (P0.983Si0.027)Σ1.010O4. Compositional variations suggest that the (Th + U) contents are controlled mainly by the coupled substitution (Th, U) + Ca = 2REE. Calculated U-Th-Pb chemical ages based on the assumption that the initial Pb is negligible are 61 ± 11–69 ± 10 Ma (2σ) and consistent with previously reported radiometric ages for the Kabasan granitic body.

A new synonymy of coelotine spider is proposed through a comparison of the morphological characteristics and the results of our molecular analysis. Coelotes hachijoensis Ono 2008, described on the basis of specimens from Hachijo Island, is a junior synonym of Coelotes oshimaensis Shimojana 2000. The original distribution of C. oshimaensis is considered to be on Amami-oshima Island and the Tokara Islands in southwestern Japan, far from Hachijo Island. Various circumstantial evidences suggested that C. oshimaensis on Hachijo Island may have been artificially introduced from Amami-oshima Island.

Since childhood, I have been unable to share my experiences with those around me and lived in chaos. With a diagnosis of autism spectrum disorder, I recognized myself as a member of a minority group and gained connections to minority communities. On the other hand, I also experienced the unfairness of being overly blamed for miscommunication. Therefore, based on the social model of disability, I conducted tojisha-kenkyu in order to explore my characteristics and the conditions of the environment that suited those characteristics. As a result, I was able to gain knowledge about my characteristics behind communication difficulties and how to guarantee informational accommodation appropriate for these characteristics. Although this knowledge improved my current wellbeing, the traumatic memory of the past remained afterwards, and I was unable to integrate my present and past selves. However, the knowledge from others who knew the past gave meaning to such memories and enabled me to construct an integrated self-narrative. The above process of tojisha-kenkyu brought about knowledge that made it possible to connect with the body, the world, and the past, but this knowledge was at the individual level. It was only by acquiring historical knowledge that enabled me to situate my own tojisha-kenkyu in the genealogy of the knowledge of tojishas, which I received from my past peers, updated and transferred to my subsequent peers, that I was able to challenge the exclusive society.

Recent extension of the container transport system has lead to the remarkable increase in both speed and size of container ships. Since there is a practical limitation to the maximum output of an individual engine, multiple-screw propulsion will become necessary for a large container ship to attain a higher speed with a large capacity of transport than the speed of 25 knots. Comprehensive research works have been conducted with the aim at developing a high speed container ship with triple-screw to be built at Mitsui Shipbuilding & Engineering Co., Ltd. in 1972, for the service between Europe and Japan.This report deals with comparative tests among single-, twin- and triple-screw propulsions, and with mutual interference between the hull and propellers, cavitation researches and full-scale measurements on the triple screw ship. Such other items of research works as vibratory forces of the propellers will be reported in a later paper.Principal conclusions obtained are as follows, 1) A triple-screw ship has a better propulsive performance than a twin-screw ship.2) For the triple-screw ship adopted, inward rotation of the wing propellers gives better propulsive efficiency than outward rotation, which is explained both by the wake measurements by 5 hole pitot tubes and by the results of the self-propulsion tests.3) Mutual interference between the center and wing propellers can be neglected practically.4) The effect of variation of the load of a propeller on the self-propulsion factors of each propeller will be negligible, unless the variation is too large.5) Added resistance of the appendages is also subject to the scale effect.6) Decreasing the camber of the propeller section near the leading edge was shown to be an effective means to decrease the amount of back cavitation, both on the ship and on the model.

Two patients, 48- and 50-year-old sisters, presented with a characteristic facial appearance with slowly progressive deafness and cerebellar ataxia starting in their 30s. Genetic testing identified compound heterozygous pathogenic variants in the ERCC6 gene: c.1583G>A (p.G528E) and c.1873T>G (p.Y625D). A diagnosis of Cockayne syndrome (CS) B type III was made. CS is usually diagnosed in childhood with well-defined facial characteristics and photosensitivity. This case report describes rare cases of adulthood CS with a primary presentation of slowly progressing deafness and cerebellar ataxia. CS should be considered in adults with characteristic facial and skin findings, deafness, and cerebellar ataxia.

ナラ枯れは、江戸時代以前から日本で発生しており、過去の被害は周辺に拡がらなかったが、1980年代以降、全国的に拡大するようになった。京都府では、1990年代に被害が発生し、2011年以降は終息に向かったが、被害が再発している地域も多い。 ナラ枯れの発生原因についても、主因、誘因、素因に別けて考えるべきであろう。主因は、カシノナガキクイムシが媒介する糸状菌(Raffaelea quercivora)であることが証明された。誘因については、2005年の総説で、ブナ科樹木の大径化を指摘した。すなわち、燃料革命で化石燃料の利用が増え、薪炭林(里山よりも奥山に多い)が放置され、カシノナガキクイムシが繁殖しやすい大径木が増えたことを指摘した。この説が定説になってしまったが、総説では温暖化の影響も指摘した。しかし「温暖化を原因とする説が提唱されたこともあったが、60年以上前に冷涼な地域で発生しており、関連性を示すデータは得られていない」と反論され、科学的な検証を試みる人はなかった。そこで、演者は、温暖化がナラ枯れに与える影響について検証してきた。ここでは、温暖化がナラ枯れの要因であることを示す。
