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。

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.
