Realist Japan? An examination of Japanese foreign and security policy under Abe Shinzo in three case studies
No full textHow can international relations theory best explain the motivation and dynamism behind the making of Japan’s foreign and security policy in the twenty-first century? This research provides one answer to this question by examining the policymaking of the Abe administration from 2012 to 2020 (also known as ‘Abe 2.0’). It is still theoretically puzzling as to why and how the Abe administration could bring about historical changes in Japan’s foreign and security policy. Structural realism might attribute such policy shifts to a changing of balance of power. Meanwhile, constructivism argues that the changes of domestic identity and norms would matter. Although different theories may have some explanatory power, this research argues that none of these approaches can solely explain the mechanism of Abe 2.0 foreign and security policy. Rather, as argued here, neoclassical realism (NCR) that incorporates domestic factors into a systemic analysis can best explain the changes in Japan’s foreign and security policy during Abe 2.0. To make this case, this thesis tests a NCR framework in the three exemplary cases of Japanese foreign and security policy under Abe 2.0: 1) security policy reforms and alliance management with the United States; 2) the management of Japan-China relations; and 3) the promotion of the Free and Open Indo-Pacific (FOIP) concept. Relying principally on Japanese-language sources and qualitative data, it reveals that domestic factors, especially leader images and policymaking processes, played significant roles to translate structural factors, namely the rise of China, into specific policy planning and outcomes. It concludes that while systemic stimuli primarily drove Japan’s realist shift in foreign and security policy, domestic intervening variables solidified policy agendas and approaches and occasionally moderated policies in a more practical rather than strictly realist direction.</p

Non-Collimatorによるシンチグラムの画像復元について
No full textWe have conducted an experiment on restoring scintigram images obtained without the use of collimators. Uncollimated images of liver slice phantoms filled with 99mTc were taken at a phantom-camera distance of 0 cm. The sensitivity under these conditions was about one thousand times higher than that using a low-energy high-resolution collimator. Uncollimated images were restored using unsharp masking in combination with spatial filtering. The unsharp masking process involved subtracting two images taken at phantom-camera distances of 0 and 2.3 cm to produce a difference image. The mean squared errors found were 0.56 for the uncollimated images, 0.54 for the images processed with the spatial filter only, and 0.53 for the images produced using unsharp masking followed by spatial filtering. Thus, the images processed using both unsharp masking and the spatial filter bore the closest resemblance to the actual images. Also, since this method was capable of revealing the shape of the phantom, it may already be usable for imaging large lesions, such as in lung perfusion scintigraphy.「久保直樹，花田博之著：Non-Collimatorによるシンチグラムの画像復元について, 北海道大学医療技術短期大学部紀要，8, p.151-156(1995)」の英訳
Obligatory roles of dopamine D1 receptors in the dentate gyrus in antidepressant actions of a selective serotonin reuptake inhibitor, fluoxetine
No full textDepression is a leading cause of disability. Current pharmacological treatment of depression is insufficient, and development of improved treatments especially for treatment-resistant depression is desired. Understanding the neurobiology of antidepressant actions may lead to development of improved therapeutic approaches. Here, we demonstrate that dopamine D1 receptors in the dentate gyrus act as a pivotal mediator of antidepressant actions in mice. Chronic administration of a selective serotonin reuptake inhibitor (SSRI), fluoxetine, increases D1 receptor expression in mature granule cells in the dentate gyrus. The increased D1 receptor signaling, in turn, contributes to the actions of chronic fluoxetine treatment, such as suppression of acute stress-evoked serotonin release, stimulation of adult neurogenesis and behavioral improvement. Importantly, under severely stressed conditions, chronic administration of a D1 receptor agonist in conjunction with fluoxetine restores the efficacy of fluoxetine actions on D1 receptor expression and behavioral responses. Thus, our results suggest that stimulation of D1 receptors in the dentate gyrus is a potential adjunctive approach to improve therapeutic efficacy of SSRI antidepressants. © 2018, The Author(s).1
Synthesis of Mo–Si–B in situ composites by mechanical alloying
No full textIn this study, the synthesis of Mo-Si-B multi-phase alloys, so-called in-situ composites, was attempted with the combination of mechanical alloying (MA) and spark plasma sintering (SPS) processes. MA was conducted with mixed powders of Mo, Si and B using a planetary ball mill under various milling conditions. MAed powders were characterized by X-ray diffractometry (XRD) and scanning electron microscopy (SEM). The results obtained by XRD indicated that Mo-Si-B alloyed powders were successfully produced when elemental powders were milled at a higher milling energy. Vacuum heat treatments after the MA process promoted the formation of Mo-Si-B intermetallic phase in MAed powders. On the other hand, the MAed powders were successfully consolidated by a SPS technique, and as a result, sound compacts of Mo5SiB2-based composites were synthesized
