In The Aporia of Mind: Space, Body and Meaning, Noya tried to answer two difficult philosophical problems about the world and other minds. And his answers were given mainly by the elimination of person from his theory of Cyoubou. In this paper, I examine his arguments and explain why sceptics would not be fully satisfied with his solution. First, I argue that the explanation of the unity of multimodal perceptions should require person. Second, I insist that person is needed for the individualization of the body and show that the subject of experiences can be separated from that of acts. Finally, after showing the difference between actuality and reality, I point that Noya's theory missed the problem of the other lives in the different actuality.

In this paper, we present a logical system which is constructed on the following principles: I) the singular proposition is a universal proposition with a singular term as its subject; II) the identity proposition is a singular proposition with a singular term as its predicate; III) a singular term is a term which designates the only one object. The resulting system is shown to be inferentially equivalent to the original system of Lesniewski's Ontology dating from 1920. We shall present some results on the comprehension axiom and the law of extensionality, too.

Until now, Many philosophers have tried to elucidate plurality of epistemic norms in terms of plurality of aims with which we acquire knowledge. In this paper, I try to elucidate them in terms of plurality of aims with which we evaluate knowledge. For this purpose, I construct the new knowledge model which is composed of the idea of Attributor Contextualism and the conception of language games by Wittgenstein. With this model, I want to suggest a new research program of epistemology which can contain both Internalism and Externalism that have caused a lot of controversy in contemporary epistemology.

The symptoms of borderline personality disorder (BPD) are often observed in young adults. They have difficulty in adaptation. Therefore, it is important to assess the extent of their BPD symptoms to ascertain intervention. However, there is no scale to assess BPD symptoms and their changes in young adults in Japan. Therefore, we developed a Japanese version of the Quick Evaluation of Severity over Time (QuEST-J) to assess these symptoms and investigated the reliability and validity of this scale in a sample of Japanese undergraduates (N=733). QuEST-J comprises three sub-scales: “Thoughts and Feelings,” “Behaviors-Negative,” and “Behaviors-Positive.” A confirmatory factor analysis corroborates the factorial validity. Moreover, the results indicate enough internal consistency, test-retest reliability, and criterion-related validity. Therefore, QuEST-J is a reliable and valid scale to assess BPD symptoms in young adults.

Long-term paleo-seismic history is significant for the understanding of earthquake mechanisms and the assessment of earthquake and related hazards (e.g., tsunami). Especially, tsunami deposits research progressed after the devastating large tsunamis (e.g., the 2004 Indian Ocean earthquake and 2011 Tohoku-oki earthquake) and paleo-tsunami deposits have been identified all over the world. In the terrestrial environment, it is generally difficult to find an appropriate site for revealing the long-term paleo-tsunami history and such appropriate sites were limited due to landform development and artificial modification. It is true along the Pacific coast area in the Tohoku region, northeast Japan. However, the authors found the most appropriate site for the reconstruction of long-term paleo-tsunami history on the Sanriku Coast. This is the Koyadori site, where organic fine sediments accumulated continuously since Towada-Chuseri (To-Cu) tephra (ca. 6 ka; Mclean et al., 2018) and sediments supply from surrounding are small except for tsunami deposits. In this study, we show the ages of paleo-tsunami deposits since 6 ka and their subsurface distribution in Koyadori lowland based on dense and many excavation and drilling surveys. From 2012 to 2015, we conducted trench excavation survey (Ishimura and Miyauchi, 2015), outcrop survey (Ishimura and Miyauchi, 2015), drilling survey (Ishimura et al., 2014), short Geoslicer survey (Ishimura et al., 2015), and long Geoslicer survey from 200 m to 400 m distance from the coastline and used these samples to this study. In the laboratory, we conducted the radiocarbon dating, tephra analysis, μXRF analysis, and gravel roundness analysis for lateral correlations of sediments. In this study, we mainly used five long Geoslicer samples. All samples reached To-Cu tephra and, that is, they record a continuous 6 thousand years history. From these samples, we confirmed that there are 14 tsunami deposits including the 2011 event after To-Cu tephra and the average recurrence interval is estimated to be 300-400 years. Subsurface distribution of them was revealed by sedimentary facies, geochemical signature, gravel roundness, and radiocarbon dates of long Geoslicer, short Geoslicer, and drilling cores. As a result, the most appropriate site in Koyadori for tsunami deposits research is limited only 300 m to 350 m area distance from the coastline. On the other hand, in the seaside area behind the 5-m-high beach ridge (200 m to 300 m distance from the coastline), large erosion occurred a few times after To-Cu tephra and these erosions were not expected from the present topography. This indicates that we need to care buried topography and to conduct a multi drilling survey. Takeda et al. (2018) pointed out a similar thing. This study gives us clues for tsunami deposits identification and accurate lateral correlation of sediments. Dense drilling surveys and/or continuous outcrops tell us an accurate number of tsunami deposits. Tephra layers give us robust ages and correlative layers in sediments. A geochemical signature can be used to correlate background sediments and gravel roundness is useful to identify tsunami deposits and correlate them. Radiocarbon dating gives us confirmation of the lateral correlation of sediments. We thought that this is an efficient procedure for paleo-tsunami deposits research.

本学部では e ラーニングによる入学前教育を実施しており,プログラミングの課題も含まれている.本研究では,受講対象者である高校生をチューターと学習者に分け,学習者が作成したプログラムに対して,チューターが確認を行うためのオンライン上の学習環境を構築した.そのシステムは,学習者がビジュアル型言語でプログラムを作成して提出するまでの履歴を記録し,チューターがプログラムや履歴を確認して学習者にフィードバックを行うことを支援する.構築した学習環境を用いて入学前教育で試行した結果,チューターの確認とフィードバックにより,学習者のプログラムの改善が見られた.一方で,履歴を提示することはチューターの役に立っていたが,プログラムの確認やフィードバックには不十分な点が見られるなどの課題が残った.その課題を踏まえ,システムの改善について検討した.

脳動脈瘤の治療法はclipping, coil embolization, by pass+parent artery occlusionの3種類に大別されるが,困難な症例ほど単一の治療法のみにならない判断が必要になる.このためには治療チームとして上記3種類の治療技術を高いレベルでもち.柔軟性をもった治療計画を立てることが必要である.手術手技についても基本的な方法を大切にしたうえで.体位やアブローチ,剥離操作などを症例に応じてmodifyすべきであり,単一のやり方に偏りすぎるべきではない.安全に外科治療を行ううえには,術前・術中に次のステップで起こりうるリスクに備えそれを防ぐことと,手術器具について基本的知識をもつことが大切である,
