Humans can perform fast and skillful manipulations using various parts of the body by effectively utilizing the dynamics of the targets. Visual sensation is the most important human sense used for such manipulations. It is obviously preferable that robot can perform various tasks using same end effectors like a human hand and using visual information. Juggling is one such example involving skillful and dynamic manipulations, and visual information is essential for it to be successful. Previously, there have been several studies about robotic juggling. However, none of these studies have considered cases in which a human-like multifingered hand-arm is used for the robotic juggling. The purpose of this study is to achieve two-ball juggling using our robotic hand-arm, which has three general purpose fingers, and stereo vision. The trajectory of the robotic hand-arm is generated based on the ball's estimated dropping position and moment, and the robot catches the ball. The juggling motion is achieved by repeating this cycle.

The Kabasawa placer deposit is categorized as one of the Pliocene ilmenite placer deposit and its sedimentary and conservative environment is controlled by warping movement of the Okubushi line. the purpose of this paper lies in the research of such elements which influenced the deposition of the Kabasawa placer deposit characteristics relating to type of movement, behavior and development stage of the Okubushi line made during the Pliocene era. The Okubushi line consists of combinations of cross structure of NW and NE branches meeting at tangent angles to each other which reflects the tectonics in the basement of this area. Of these, the NW brach plays a main role in the tectonic movement. The NW branch of Okubushi line controlled the deposition in Pliocene Sendai Group as well as Pliocene sedimentary basin after making warping movement and bringing about an upheaval on its southwestern side and tilting subsidence on its northeastern side. In other words, the NW branch brought about a differential movement of upheaval and subsidence through the depositional stage of Kameoka and Tatsunokuchi formation and the central part of the past upheaval changed into a depressional tilting subsidence at the depositional stage of Kitayama formation. Finally, the NW branch terminated its geologic movement with the eruption of tuff (acidic volcanic deposits) at the depositional stage of Hirosegawa tuff. The Kabasawa sandstone and conglomerate member intercalating Kabasawa ilmenite placer deposit, is a deltaic deposit which was piled up upon the region of depressional tilting subsidence during the depositional stage of Kitayama formation. It forms a circle of 2km diameter and has an extraordinary thick stratum. It is generally believed that the movement in the NW branch of Okubushi line is the result of a tectonic movement, referred to as “Green Tuff Crustal Movement”, in full activity during the Miocene era and succeeded to the Pliocene era in the northeastern part of Japan.

To improve the yield of a Japanese tomato (Solanum lycopersicum) cultivar and determine how fruit yield changes as a result of grafting, we investigated the effects of a Dutch rootstock [‘Maxifort’ (S. lycopersicum × S. habrochaites): Mx] on the dry matter (DM) production and fruit yield of Dutch and Japanese cultivars. The Japanese cultivar (‘Momotaro York’: My) grafted onto Mx (My/Mx: scion/rootstock) had significantly higher fresh and dry weights of fruits per unit area than My/My. Fruit fresh weight yield per unit area was highly correlated with fruit dry weight (DW) yield (r = 0.96–0.97, P < 0.001), and DW yield was significantly correlated with total aboveground DM (r = 0.71–0.96, P < 0.001) and with DM allocation to the fruits (r = 0.52–0.75, P < 0.01). Total aboveground DM (TDM) was significantly and highly correlated with light-use efficiency (r = 0.98, P < 0.001). However, there was no significant correlation between light-use efficiency and the maximum photosynthetic rate, stomatal conductance, or the light-extinction coefficient. Although stomatal conductance significantly (P < 0.05) differed between the rootstocks at 57 and 119 days after transplanting (DAT), there was no significant difference in the maximum photosynthetic rate between the scion/rootstock combinations at 57 and 119 DAT. These results indicated that the fruit yield of My could be improved by grafting onto Mx, and that the increases in yield and TDM were mainly determined by the increase in light-use efficiency.

Borna disease virus (BDV) infection causes neurological disease in cats. Here, we report BDV infection in 199 hospitalized domestic cats in the Tokyo area. BDV infection was evaluated by detection of plasma antibodies against BDV-p24 or -p40. BDV-specific antibodies were detected in 54 cats (27.1%). Interestingly, the percentage of seropositive cats was not significantly different among the three clinical groups, i.e., healthy (29.8%), neurologically asymptomatic disease (22.2%) and neurological disease (33.3%). The specific antibodies were present even in cats aged below one year. The seropositive ratio was constant, irrespective of age and sampling season. The present study suggests that additional factors are required for onset of Borna disease in naturally infected cats and that BDV is transmitted through vertical routes in cats.

A dog developed a cervical mass, and computed tomography verified a mass surrounding the trachea with some pulmonary masses. Histopathologically, the cervical mass was composed of malignant neoplastic cells showing follicular appearance which reacted positive for thyroglobulin on immunohistochemistry. A characteristic feature of the tumor was abundant and metaplastic stromal components. Anastomosed collagenous tissues connecting to capsule of the tumor were abundant in the stroma. In parts of the collagenous tissues, mature cartilages and bones were continuously formed. There was no cellular atypia or invasion in the components. We diagnosed this case as follicular thyroid carcinoma with metaplastic stroma. This is the first case report that characterizes stromal components with chondroid and osseous metaplasia in a canine thyroid carcinoma.

A 9-month-old intact female Yorkshire terrier dog was presented with episodic partial seizure-like cramping of the limbs. The patient’s episodes began six months previously; the interval between episodes became shorter, and the duration of the episodes increased. Various tests including neurologic examination, blood examination, abdominal radiography, ultrasonographic examination, angiographic computed tomography (CT) and brain magnetic resonance imaging (MRI) detected no remarkable changes. After these tests were conducted, the patient’s condition was suspected to be canine epileptoid cramping syndrome (CECS), which could be a form of paroxysmal dyskinesia (PD), and as a trial therapy, Science Diet k/d (Hill’s Pet Nutrition, Topeka, KS, U.S.A.) was prescribed. The clinical signs were dramatically reduced after diet therapy, and we diagnosed the patient with CECS. This is the first case report of CECS in a Yorkshire terrier dog.

Old seismograms of the Tokyo earthquake in the Meiji era (June 20, 1894) were analyzed to retrieve source parameters. This earthquake gave considerable damage on the Tokyo metropolitan area. The focal depth was estimated to be about 50km or about 80km from S-P times of several seismograms observed at Tokyo. The magnitude, which was calculated from data of maximum amplitudes, was 6.6. The focal mechanism and the seismic moment were inferred from waveform fitting with seismograms observed by a Ewing-type strong motion seismograph and a Gray-Milne-Ewing-type seismograph. The estimated moment is 1-3×1018Nm (Mw=6.0-6.3). The earthquake is considered to have a nearly vertical nodal plane with N-S strike, and to have occurred in the Pacific plate or the Philippine Sea plate. Stress drop of the event was larger than the average value in the region.

Objective Partial expiratory flow-volume curves have the potential to detect mild bronchoconstriction because they are not affected by the modulatory effects of deep inspiration. The aim of this study was to investigate the relationship between the efficacy of bronchodilator therapy (BDT) in treating the cough and to assess the increase in the expiratory flow of the partial flow-volume curve at 40% above the residual volume level (PEF40) caused by treatment with a short-acting beta-2 agonist (SABA) in patients with chronic nonproductive cough. Methods We measured the reversibility of PEF40 caused by a SABA in 42 patients with chronic nonproductive cough at visit 1 (day 0). The patients received BDT for six days. The visual analogue scale (VAS) was used to assess the efficacy of BDT in treating coughing at visit 2 (day 7) (0 mm, 'no cough;' 100 mm, 'no change in coughing'). Results Reversibility of the PEF40 was correlated (r=0.690, p<0.001) with the VAS score determined at visit 2 and was higher in the patients with cough variant asthma (CVA) (44.9±18.3%) than in those with atopic cough (13.4±10.4%) (p<0.01). Conclusion Reversibility of the PEF40 predicted the efficacy of BDT in patients with chronic nonproductive cough and helped to identify patients with CVA.

This essay discusses physical culture and the establishment of the bukh system during Mongolia's socialist era and the reform of “traditional bukh” following democratization. It examines, in particular, the process through which traditional bukh wrestling has become a modern sport, focusing on the reforms the Bukh Federation has undertaken since 1990. Although this approach provides only a brief look at bukh during a short moment in its long history, it is distinguished by its emphasis on spontaneous and democratic modernization of the sport from the “inside” and from “below, ” in contrast to traditional studies, which have concentrated on the formation of a bukh system from “above” through the exercise of centralized power. The Bukh Federation, founded in 1990, took the position that “bukh is an ancient tradition that preserves in condensed form the essence of Mongolian culture.” By giving a precise definition to the concepts of “bukh wrestling, ” “wrestlers, ” and “spectators, ” and thereby reviving, revitalizing, and commercializing “traditional bukh, ” the Federation hoped to modernize the sport. This was intended, in the words of Federation leaders, to bring “traditional bukh” into the modern era. By setting up a modern bukh league with a large everyday following while stage-managing “traditional bukh” as a part of the Naadam national festival, the Federation skillfully merged this modernist discourse with the actual pratice of bukh. I call this process “the embodiment of tradition.” On the one hand, the modernization of bukh aimed not so much to internationalize the sport as to spread to other Mongolian-related groups a form of wrestling perfected inside Mongolia and reflecting a purely Mongolian ethnos. Thus, the modern reproduction of traditional bukh involves the construction of bukh culture as a symbol of a distinctly national or ethnic culture through the mutual interaction of the state and the Bukh Federation based on the twin concepts of nationalism and “tradition.”

本論文では、アイルランドの独立運動において重要な役割を果たしたGAA (Gaelic Athletic Association) が様々な揺らぎを経験しつつも、最終的にナショナリズムの波に合流していく過程を、グラスルーツ・レベルのメンバーのメンタリティに焦点を当てて検証した。GAAの各クラブは、アイルランドの近代史を語る上で重要なカトリシズム、さらにそのパリッシュ (小教区) をベースに設立された。また、土地解放運動を展開したINL (Irish National League) もGAAクラブ設立で重要な役割を演じた。カトリシズムと土地解放を中心とした自治権獲得運動、この二つのイデオロギーがGAA設立の大きなバックグラウンドであったといえる。交通網及びマスメディアが未発達の当時は、聖職者を中心とするパリッシュが人々の生存の基盤であり、また支配者階級のイギリス人地主に対抗するためパリッシュ内の凝集性は極めて高いものとなっていった。「我がパリッシュ」という「われわれ」アイデンティティとパリッシュ住民の自己アイデンティティはほぼ同一であり、いわば極めて単層化に近い構成のメンタリティがそこには存在した。このメンタリティが、さまざまな外界との接点を通して「われわれ=われバランス」に変化を来した。GAA等の活動を通したパリッシュ間、カウンティ間の交流、さらにパリッシュあるいはカウンティを横断したナショナリスト団体との繋がりによって、彼らのメンタリティの中に存在していたナショナリストとしての「層」が強固なものとなった。特にGAAの理念の中心となっていったBan (外国ゲーム禁止令等の制限ルール) により、イギリスの文化的侵略に対する認識が高まった。このことで「われわれ=Irishness」のアイデンティティが先鋭化し、占領者、占領文化に対する強固な抵抗へと具現化していった。分析の資料としてはGAAクラブ史に焦点を当て、今まであまり分析対象とされなかったグラスルーツ・レベルでの変化を検証し、独立運動へと向かった伝統スポーツの継承者たちの社会心理を浮き彫りにした。

For miniaturization of magnetic devices, it is necessary to increase the operating frequency. We have studied thin-film micro-inductors to realize a high operating frequency and reduce the iron loss. In this paper, we propose a thin-film micro-transformer with high operating frequency achieved by application of a multilayered magnetic film to the core. The magnetic core is made of amorphous CoFeSiB monolayer film or a CoFeSiB/SiO2 multilayered film. The induced magnetic anisotropy is controlled so that the exciting direction of the coil is along the hard axis. The total thickness of the magnetic layer is 3μm and the size of the core is 0.6 mm × 2.3 mm. The experimental transformers show that a multilayered core is useful for improving the transmission loss of transformers at high operating frequency. A thin-film transformer whose transmission loss is 2.7 dB from 100 MHz to 250 MHz has been developed. This value is smaller than the 5.3 dB of the monolayer core.

Fish muscle protein films were prepared from blue marlin (Makaira mazara Jordan & Evermann) meat which had been stored at 30°C to intentionally lower the meat quality. In this study, the effects of meat quality and pH on the formation of these protein films were investigated. Moreover, ε-polylysine was added to the film-forming solutions to reduce the microbial population of films. The mechanical properties of the films were slightly affected by acidic and alkaline pHs. However, the water vapor permeability of muscle protein films was not affected by either the quality of the fish meat or the pH of the film-forming solutions. SDS-PAGE (sodium dodecyl sulfate- polyacrylamide gel electrophoresis) showed the degradation of myosin heavy chain in acidic films and polymerization in alkaline films. It was revealed that biodegradable films can be produced even from very low quality fish meat, and that the bacterial population of films could be drastically reduced by the addition of ε-polylysine.

It has been well known that anisotropy in yield stress and the work-hardening rate is induced by pre-strain and aging. However, such an origin has not been adequately understood. In the present study, stress-strain curves in different directions were investigated after 2% pre-straining and post-heat treatment at 150°C in ferritic steel. When the applied strain path was changed to the orthogonal direction of the pre-straining path, the re-yield stress was lowered and the work-hardening rate in the low plastic strain was increased. The heat treatment following 2% pre-straining caused an increase of the re-yield stress in the parallel direction to the pre-strain and caused no change on the re-yield stress in the orthogonal direction. The work-hardening rate was increased in both directions after the heating. Electron back scatter diffraction pattern (EBSP) analysis was also conducted to measure the kernel average misorientation (KAM) value, which corresponded to the density of the geometrically necessary dislocation, on each [hkl]-oriented family grain for the pre-strained and the post-heated materials. The EBSP results indicated that heterogeneous work-hardening behavior among the [hkl]-oriented family grains could strongly effect the anisotropy induced by strain path change and aging.
