強化学習モデルとは,ヒトの行動選択の過程を数理的に表現するモデルであり,代表的なものにQ学習モデルがある。強化学習モデルを考える利点の一つは,主体が採用している学習メカニズムの情報を得られることである。しかし,これまで強化学習モデルは人間の手で作られてきたため,実際のメカニズムを反映したモデルを見落としている可能性がある。そこで本研究では,遺伝的プログラミングを用いて強化学習モデルを探索するAIを開発し,研究者のモデル構築をサポートすることを目指す。ところで,AIが強化学習モデルを探索できると一口に言っても,それがどのような条件下で可能かによって,実用性は大きく異なる。本研究では,AIの開発可能性を高めるために,「パラメータが特定の値をとり,選択されなかった行動の価値は更新されない」という特殊な条件下でのモデル探索を目指す。具体的には,Q学習モデルから人工的にデータを生成し,そのデータからAIが正しくQ学習モデルを探索できるか否かを検討する。開発したAIでモデル探索を行った結果,AIは正しくQ学習モデルを探索できた。今後は,より一般的なモデルを探索できるようAIを改良する予定である。

A inverter-fed permanent magnet synchronous motor with a rotor position sensor and a speed sensor is used in many industrial applications as a DC-brushless motor. In this paper, a strategy which determines the rotor position and the speed of the permanent magnet synchronous motor by using the instantaneous values of phase voltage and phase current sensing is explained.In a permanent magnet synchronous motor, the permeance of the stater magnetic circuit is altered by rotating the rotor position; the inductance of a phase winding changes according to rotor positions. Hence, the phase voltages and currents of the motor have close relations with the rotor positions. Measured values of phase voltages and currents and the values of the equivalent circuit parameters are substituted to the voltage equation of the synchronous motor. Then, we can calculate the value of the rotor position angle by that voltage equation. The rotating speed of the rotor can be calculated from the voltage equation by substituting the rotor position angle. In these calculations, we used a 16-bit micro-computer and a DSP, and for sensing phase voltages and currents, 12-bit high quality A/D converters are used.Experimental results obtained by using the prototype system were congruous values of the rotor position angles and the rotating speed.

Young men's leagues ("Seinen-dan") created by the Japanese government for the Han people in Taiwan (hereafter called Taiwanese) seem to have played a significant role in ultimately mobilizing the Taiwanese as soldiers. In previous studies I have illustrated that Taiwanese young men's leagues, that until the first half of the 1930s had been closely organized with the communities called gaisho (administrative units equivalent to towns and villages in Japan) and served as institutions for training elites. The leagues were transformed in the late 1930s into organizations used to impose military training on young people who recently graduated from elementary schools, in order to implement the three major policies of colonial Taiwan, namely "Japanization, " "industrialization, " and "southward expansion." This paper explores the system of young men's leagues in Taiwan between 1940 and 1943 when the mobilization of youth was one of the most important goals of the Office of the Governor-General of Taiwan. Around this period, the establishment of youth schools ("Seinen Gakko") for Taiwanese students was promoted and the special Army volunteer program began in earnest in 1942. By examining young men's leagues in relation to these systems, I attempt to explain the social meaning of young men's leagues within the context of colonial Taiwan, referring to Taiwan Kyoiku (the journal published by the Taiwan Education Society), magazines published for indoctrination, the official gazette published by the Taiwanese Government-General, and Kobun Ruijyu owned by the National Archives of Japan, among others. The analysis of these materials uncovered the following historical facts. In all-out war, a number of youth-oriented programs were introduced in Taiwan between 1940 and 1943, including the national elementary school system ("Kokumin Gakko") in April 1941, the special Army volunteer system in April 1942, and the compulsory education system for elementary schools and the spread of youth schools throughout Taiwan in April 1943. In this climate, young men's leagues in Taiwan underwent two major changes. In December 1941, they were reorganized as Taiwanese Youth Leagues ("Taiwan Seishonen-dan") and young men's leagues emerged as organizations closely aligned with national elementary schools while simultaneously reinforcing their identity as organizations of so-called "working youth" who chose not to go on to secondary schools and higher schools. Thus, as the governing body of working youth, young men's leagues encouraged working youth to enlist under the special volunteer system and promoted Japanization. In April 1943, as the effort to upgrade youth schools for Taiwanese began throughout Taiwan, young men's leagues were reorganized as one of the groups under the umbrella of Komin Hokokai, thereby establishing their position as an organization to bring all working youth in the community under control. In sum, it can be argued that young men's leagues, much like school education, played a central role in the indoctrination (or education) of youth in colonial Taiwan.

日本統治下の台湾や朝鮮では、学校教育を受けることのできる子どもたちは限られていた。その機会に恵まれた子どもたちでさえも、その期間は限定されていたが、子どもたちは学校以外でもさまざまな学びを経験したはずである。そこで私たちは学校教育以外の場で、子どもたちがどのような学びを経験したのか、その様相に焦点を当て多様性を明らかにした。例えば、社会教育(伝統教育機関、夜学や国語保育園など)、サブカルチャー(児童文学、紙芝居、ラジオ、労働、遊び)の中での彼らの学びである。資料としては、当時の政策文書や新聞雑誌、インタビュー調査の記録を用いた。
