During the Meiji Restoration, there was a faction of strong willed patriots called Shishi in the Choshu Domain. This was the result of the education which had been done throughout the Edo period. The schools representing that education were the domain school Meirinkan and the private school Shokasonjuku Academy by Shoin Yoshida.
In the Choshu Domain, we had some other excellent schools called Gogaku. They were built by the Mori clan and the upper samurai. They were proud of their facilities, many books, excellent teachers and students who were sons of the samurai. But little research has been done on these schools because there are only few sources whereas many researchers have focused on the Meirinkan and the Shokasonjuku.
In this study, I focus on the Ikueikan Academy, a Gogaku built and managed by the Masuda clan who reigned Susa (now a part of Hagi city) and were political top leaders in the Choshu Domain. What historical conditions led to it’s foundation and what kind of education was practiced there ? How was the relation between the Ikueikan and the Shokasonjuku, and the exchange of the students ? How did the students of the Ikueikan contribute to the political movements during the Meiji Restoration ?

Which is best, Kahoot, Quizizz, or Quizlet live? The question seems straightforward, and it is easy to find opinions on YouTube. However, after researching the published literature on the topic, we experimented using all three for ourselves, then surveyed students about it. We then combined their results with our results from the teacher perspective. We (an experienced teacher in Yamaguchi, and a new teacher in Tokyo) used the different kinds of software mainly as a tool for checking comprehension at the end of units and for vocabulary acquisition. In an attempt to answer the question of which is best, we used each tool for 4 weeks during the first semester with first and second year students at universities in Yamaguchi and Tokyo. We tried to predict what problems we might encounter as well as avoid mistakes mentioned in the literature by previous researchers. Along the way, we noted problems that arose while using them, and at the end of the semester we surveyed the students about their experience with the different kinds of software. In the survey we asked the students about their perceptions of concentration, engagement, enjoyment, learning, motivation, and satisfaction. We will reflect upon how the results or our survey compare with what the previous literature on the topic says, and hope to use the results in our future classes.

We report on the electronic structure and electronic transport properties of skutterudite CoSb3 based on density functional theory utilizing the nonequilibrium Green’s function method. CoSb3 has a non-parabolic (linear) dispersion relation near the top of the valence band, and the hole effective mass is much smaller than the electron effective mass. This is the reason for the characteristic property that hole mobility is higher than electron mobility. This is completely different from that of ordinary semiconductors. The four-membered ring of Sb, which is one of the features in the crystal structure, is important in relation to the electronic structure and electronic properties. The relation of these crystal structure features to the electron transport properties is discussed. Then, the optimization of thermoelectric properties is discussed based on the chemical potential dependence of thermoelectric properties.

In this paper, the heavy atom effect of organobismuth compounds synthesized by the author was discussed based on experimental and theoretical studies. NMR chemical shifts of organobismuth compounds are often influenced by the heavy atom effect derived from bismuth atom. In the case of bismabenzene and bismacyclobutadiene synthesized by the author and co-workers, the NMR signals assigned to be hydrogen and carbon nuclei were observed at unusual low-field region, probably due to the unique heavy atom effect. To get insight into the heavy atom effect of such compounds, I performed theoretical calculations by using Gaussian program package. Based on the comparison of chemical shifts estimated by experimental and theoretical methods, the heavy atom effect of organobismuth compounds was discussed in detail.

1970年代後半からパーソナルコンピュータが普及し始めると、各学校における活用方法についても考えられるようになった。学校へのコンピュータ導入初期には、コンピュータ支援教育（CAI：computer-assisted instruction）の考え方をもとにしたドリル問題や穴埋め、記号選択など生徒の個別指導に対応しようとする試みがなされた。理科教育における活用方法としては、自然現象をモデル化したシミュレーションやアニメーション、理科実験における計測、データ処理等に用いられる事例が見られはじめた。ただ、理科教材用のソフトウェアも十分ではなく、個々の理科教員がプログラムを作成し活用方法を探っている状況であった。
1990年代になり、コンピュータの処理能力の向上やオペレーティングシステム（以下「OS」と表記）の共通化、周辺機器の充実、インターネットへの接続などが進み、理科教育におけるコンピュータの活用方法についても様々な可能性が出てきた。
現在では、児童生徒一人一人がタブレットを持ち、ネットワークを活用したオンライン授業や自然現象の迅速な検索、またネット上の動画による自然現象の確認など、理科教育におけるコンピュータの活用は個別の学習を進めていく上で重要な役割を果たしている。
本稿では、理科教育におけるコンピュータの計測機器としての活用、自然現象のシミュレーションとしての活用の変遷をたどりながら、理科教育の本質を捉えたコンピュータの活用方法はどうあるべきかについて述べる。

Recently, research on solving regional problems through industry-academia-government collaboration has been
promoted in Sanyo-Onoda city area. As part of this research, through a proposal from Mr. Nakamura of West Japan Jibie Farm, a study on "Countermeasures against wildlife damage using drones and ICT," was started from April 2020. Thetemporal goal of the research was defined to be "ecological survey of wild boars utilizing ICT", i.e. (1) survey of traces ofwild boar inhabitation by actually exploring the mountain area, (2) the development of remote observation technology of wild boars at Wallows and Beast Roads discovered by reconnaissance, and (3) the development of infrared photography technology during midnight by drone in open areas.
The results of research can be summarized as follows. (1) A total of about 17 km was explored in the back mountains of the Kataobata and Imojiya area, two Wallows and one Beast Roads were found, and a remote observation camera was set up. (2) We developed an extremely power-saving system that can monitor the nighttime behavior of wild boars over a wide area in deep mountainous areas where it is difficult to access frequently. The system combines a 2.4GHz wireless terminal (Twelite), an infrared sensor for detecting wild boars, an LPWA wireless network, and a solar cell. (3) A total of 146 night-behavior wild boars were confirmed. It was revealed that wild boars act relatively early from 19:00 to 23:00, and that deers have begun to advance into the Asa area (10 cases). (4) The night photography of wild boar by drone was successful for the first time at 21:00 on March 19, 2021. Since it was assumed that the fallow reed bed in the Kataobata area was a roost of wild boars, we developed an automatic surveillance recipe and patrolled at night.

We evaluated the reflection and transmission characteristics in the microwave region of metal granular composite
materials containing flaky Cu particles, flaky Ag-coated Cu particles, and acicular FeCo nanoparticles as anisotropic
shape particles. In the flaky Cu particle composite and the flaky Ag-coated Cu particle composite, a significant jump of the ac conductivity σ with the particle content was observed at the percolation threshold φc at 4 and 3 vol.%, respectively; the σ of composites with particle content above φc showed a value above 10-1 S/cm. The 6 vol.% flaky Ag-coated Cu particle composite exhibited metallic reflection and transmission properties. On the other hand, the 6 vol.% flaky Cu particle composite showed a tendency for the transmission coefficient to decrease and the reflection coefficient to increase with increasing frequency. For the acicular FeCo nanoparticle composites, the electrical conductivity was low and the permeability was not affected by eddy currents even in the GHz range. The 49.9 vol.% acicular FeCo nanoparticle composite exhibited the frequency dispersion of permeability by magnetic resonance at several GHz, and the 10 vol.% composite showed slight absorption above 10 GHz.

In open string field theory, we performed numerical calculations with the level truncation approximation method in
a-gauge for “double brane” and “ghost brane” solutions in addition to the tachyon vacuum solution in the previous work. These solutions were constructed from one of the solutions in the Siegel gauge at the truncated level 0, 2, and 4, respectively, up to truncated level 20, and their gauge invariants were evaluated for various values of a including a=∞, which corresponds to the Landau gauge. Although these are obtained by restricting the space of string fields to the space spanned by the twist-even universal states, some solutions other than the tachyon vacuum and “double brane” solutions exist at the second lowest truncated level. Here, we evaluate gauge invariants for them and study their behavior. Namely, at the truncated level two, starting from all solutions obtained in a=0 or a=∞ gauge, we construct numerical solutions in various a-gauges by varying the values of a gradually and describe their gauge invariants. Our results might become useful for constructing new physically meaningful solutions at the large truncated level limit.

天災や人災が立て続けに人類を襲い、現下の新型コロナ感染症の蔓延に至り、人類は大きな試練の渦中に置かれてしまった。産業は低迷し、土台を支える日本の科学技術の世界での地位が相対的に下がった。国力低下の大きな根源である人口減少を前提とした、日本の競争力を回復する科学技術研究や教育の在り方を今こそ考えなければならない。近年の社会変化の中で科学技術に対する見方も変わった。研究者・技術者は自己の価値観を大切にし、環境や社会に対する強い識と高い倫理観を有することが必要となった。産業界の変化に伴い採用する人材は即戦力化してきたが、一方で、企業の価値創造を担う技術者が求められている。科学技術や工学に携わる者は、人類の生存や地球環境の維持に、いっそう目を向けなければならない。人口減少に対しては科学技術を駆使して広義の生産性向上の研究を推進し、個人の行動効率化のためには知識科学教育を行うべきである。科学技術の成果を展開するにあたっては、企業で用いている生産性向上やコミュニケーションのツールも役に立つ。イノベーションのためには戦略が必要とされるが、立案には客観的な情報収集・分析と世の中の技術や研究の変化への俊敏な対応が不可欠である。研究資源の８割を企業が有するが、その効率的運用を図る必要があり、自社の得意分野に絞った研究投資を行い、他はオープンイノベーションに委ねることが肝要である。研究費の効率を論ずることは難しいが、研究開発のプロセスを細分化して新たな指標とその分解指標を用いた、きめ細かい管理手法を提案する。効率的な研究には企業連携や産学連携が重要であり、双方の役割を明確にして実行することが成功につながる。教育については、企業の目的志向の幾つかの手法を大学でも活用したい。学びは生涯を通じてのものなので大学では知識よりも学ぶ術を身に着けるようにしたい。学ぶ方法も学生同士が教え合い、意見交換するような形を授業に反映したい。そして、学ぶ熱意を醸成するために、学生は大学の早い時期に将来の夢や目標を見出して欲しい。
