It is commonly known that C. I. Lewis started modern modal logics (S1-S5) because of his dissatisfaction with material implication. But his original intention was to construct a logic of strict implication rather than a logic of modality. Then he had got involved in the latter gradually against his original intention. In this paper, I clarify where his original intention lay and how he was involved in modal logics tracing his writings chronologically. Considering his contemporary logicians' responses, I sum up the argument.

【目的】軽微な頭部外傷後の脳梗塞症例の臨床, 画像的特徴, 特にmineralizing angiopathy (以下MA) との関連を検討する. 【方法】1980年4月から2016年11月までに脳梗塞の診断で当院に入院した患者の診療録を後方視的に調査し, 軽微な頭部外傷後の脳梗塞患者を対象に, 臨床, 画像的特徴について検討した. 【結果】動脈性脳梗塞と診断された119例のうち5例が軽微な頭部外傷後の発症であった. 発症年齢は10か月から11歳 (中央値は2歳9か月) で全例男児であった. 1例で無症状, 4例で左片麻痺を認め, 全例予後は良好であった. 頭部画像は4例は右側, 1例は左側の大脳基底核に梗塞像を認めた. 5例中, 麻痺を認めた4例にCTで穿通枝のMAと考えられる線状の高吸収域を認め, うち3例は両側に認めた. 11歳の症例では今回の梗塞像の対側基底核に陳旧性梗塞像を認めた. 【結論】軽微な頭部外傷後の基底核梗塞症例で高率に穿通枝にMAの合併を認めた. 脳梗塞の原因となるその他の因子は明らかとなっておらず, MAが軽微な頭部外傷後の脳梗塞と関係がある可能性が疑われる. 軽微な頭部外傷後脳梗塞は乳幼児の報告が多いが, 本検討の最高齢は11歳で既報より高かった. 乳幼児期以降にも軽微な頭部外傷後脳梗塞の発症があることや, 再発の可能性を考慮する必要があると考えられた.

We can perceive small color differences, and we can also perceive color as a group of many different colors (categorical color perception). Visual performances based on small color differences are known to be better in the central visual field than in the periphery. We have clarified the characteristics of categorical color perception in the peripheral visual field. Observers were shown color chips of the OSA Uniform Color Scales set in the central or the peripheral visual field. The chip, which subtended 4deg, was presented at the fovea (Odeg), eccentricities of 30, 50, and 60 deg in the nasal visual field and of 30, 50, 70, 80, and 90 deg in the temporal visual field. A large gray surrounding field was made with a hemisphere and illuminated at a moderate intensity of D65 lights (yielding 2000 scotopic td) to suppress rod activity. The observers reported color appearance of the stimulus with one of the eleven basic color terms. The distributions of the color categories on the xy chromaticity diagram varied little between stimulus locations from 30 deg to the nasal and 70 deg to the temporal visual field. The results of eccentricities greater than nasal 50 deg and temporal 80 deg were remarkable different from those in the locations closer to the fovea. Our results suggest that categorical color perception in the central visual field is maintained across a wide area of the peripheral visual field.

The finless porpoise has characteristic tubercles on its dorsal ridge. These tubercles are supposed to have biological and mechanical functions. In the former, specific nerve endings and fibers exist in the tubercles indicating its function as a sensory organ. In the latter, tubercles provide fluid dynamic functions such as underwater drag reduction or inhibition of wave or spray drag while breathing at the sea surface. This research focuses on the latter function aiming at the application to the drag reduction in moving vehicles. Small projection models, or tubercle models were fabricated with resin and tested in the wind tunnel to investigate the effect on the lift and the drag characteristics of an airplane model with the tubercle models attached on the wing-fuselage connection. In consequence, it was shown that the tubercles effectively delayed the wing stall at high angles of attack without largely degrading the wing performance. The oil flow experiments also clarified that this delay of wing stall was caused by the inhibition of flow separation on the wing surface. The tubercles then had a positive influence on the flow around the wing or fuselage effectively inhibiting the flow separation and thus may be a useful device to reduce drag, noise, or vibration of moving vehicles.

A display of the enormous amounts of historical material connected with Hirata Atsutane and the Ibukinoya Juku kept by the Hirata family is to be held in October this year at the National Museum of Japanese History in Sakura. The presenter was involved in the organization of several thousand pieces, mostly connected with the publication and distribution of Hitrata Atsutane's works. I have also been researching the affect they had on society. Research until now regarding Atsutane's publications have focused on publishing during his lifetime, from Bunka 10 (1813) to Tenpou 14 (1843). This presentation, while utilizing this research, will also seek to look into publishing beyond his death.Hirata Atsutane's written works were printed and spread widely following his death, through the end of the Edo and into the Meiji period. The volume printed and sold goes beyond comparison with that during his lifetime. It is clear that the method of sales and gathering money to cover publishing costs differed before and after his death. At the same time, particularly during the Bakumatsu period, due to the nature of his writings, care had to be placed in avoiding political persecution. Among his works there were some that for a time only found their way into people's hands as hand-copied manuscripts, and some, such as the case of the second volume of Tamadasuki, were printed well after the others in the series.This presentation will examine these works of Atsutane's that were forced to drift between being distributed and simply not printed, based on new historical material.There is a connection between the problems of the need for and reception of Hirata's publications, that is, his version of Kokugaku, and the "level of education" (including that involving Japanese "classics" centered on mythology) within society from the end of the Edo through to the Meiji period, which also connects with the theme of the conference.
