江木千之と文政審議会（1）－義務教育年限延長案の結末－
No full textEgi Senshi who was inaugurated as the Education Minister in January in 1924, newly organized the Council on Educational Affairs and proposed the draft of law for the two years expansion of the length of the term of the compulsory education. However, the Education Minister Okada Ryohei of the Cabinet under Premier Kato Takaaki who took power in June of the same year withdrew the draft. In this paper, the author makes much of a fact that Egi Senshi and Okada Ryohei were the same mind and makes clear the aims of the two persons which lurked in a conclusion.departmental bulletin pape

北一輝の辛亥革命に関する「電文集」と「報告書簡集」について : 内田家資料による
No full textAt the end of October in 1911, Ikki Kita, by order of Ryohei Uchida (内田良平), went over to Shanghai to give support to the revolutionary army. His activities in China were informed to Uchida in detail by thirteen letters and fifty-nine telegrams. These reports are now preserved by Mr. Osamu Uchida (内田治), son-in-law of Ryohei. In this article, the author studied the thought of Ikki Kita on the Chinese Revolution through these materials, especially through his letters. His political thought seems to have showed us the proper and reasonable attitude of Japan, which may be adaptable for us in the present also, in the relations with China. Finding two errors in the formerly accepted opinions on Kita's going to Shanghai, the author tried to correct these errors. The author's study on the telegrams, which could not be dealt with in this article, will be published in the other one
小説教材の読みに関する学習者論的研究 : 「トロッコ」(芥川龍之介)の場合
No full textThis research clarified conceived learners in teacher's interpretations. Three patterns of interpretation processes that were recursive reading of Ryohei's personality between two times in his childhood and adulthood, reading as different roles among teacher and learners, and reading through expanding sympathy with Ryohei was pointed out as the result of considerations. Then author have revised conceived learners by focusing on narrator
Quasi-solid-state self-assembly of 1D-branched ZnSe/ZnS quantum rods into parallel monorail-like continuous films for solar devices
No full textTranslating the extraordinary optoelectric properties of colloidal quantum rods (QRs) into functional devices requires multiscale structural control to preserve the nanoscale attributes as well as to introduce micro- and macroscale interactions between the building blocks. Self-assembly of anisotropic QRs into ordered nanostructures can tailor the photoelectric properties of the QRs, such as in light absorption, and charge separation and transfer. However, it remains a challenge to assemble anisotropic nanomaterial into centimeter-sized, multilayered continuous films that retain nanoscale properties in the fabricated macroscopic devices. We have developed a quasi-solid-state self-assembly of randomly oriented nanostructures for overcoming this challenge, demonstrated by the re-assembly of randomly packed ZnSe/ZnS QRs into aligned and ordered parallel monorails (PMs). These ZnSe/ZnS PMs show significant enhancement in photo-excited charge transport, boosting photocatalytic oxygen evolution rates and the enhancement of photoelectrochemical activities, with a photocurrent density of 18 μA/cm2 , 5 times higher than the parent random packing of ZnSe/ZnS QRs. The ZnSe/ZnS PMs enrich the p-n heterojunctions, which can modulate charge carrier separation and transport at the interfaces. The new method has applicability for re-assembling randomly packed films of anisotropic nanoparticles into ordered nanostructures. Importantly, the extraordinary photoelectro-energy conversion behavior of the Type-I core/shell quantum materials illuminates the pathways for novel designed materials by tailoring the hierarchical structures at all scales.Dechao Chen, Huayang Zhang, Keisuke Miyazawa, Ryohei Kojima, Peng Zhang, Lei Yang, Qiang Sun, Guosheng Shao, Takeshi Fukuma, Yongsheng Gao, Nam-Trung Nguyen, Colin L.
