How can we get Japanese university students to give longer answers in spoken English? Longer answers come from being comfortable with using the target language. In this study, first I review some of the previous literature about increasing speaking output. Then, I will report on my own research. Two sections of the same class were taught by the same teacher for both 1st and 2nd year university students. The target independent variable was use of the Flipgrid website for oral submissions as well as reviewing other submissions. The working hypothesis is that being able to practice and being able to hear other submissions will lead to students giving longer oral responses during speaking tests. The two test groups used the Flipgrid website throughout the semester, and the two control groups did not.'Using Flipgrid'means to upload a submission as well as review at least two others for each of 6 assignments. Beginning and end-of-semester oral exams were given to 4 groups of students. The number of words per response for every student were calculated, and the results are presented in this study. I will reflect upon how the results of my study compare with what the previous literature on the topic says, and hope to use the results in future classes.

Semiconducting clathrates are attracting a great deal of attention as potential candidates of thermoelectric material based on a design concept called Phonon Glass and Electron Crystal (PGEC). Since most of the thermoelectric clathrates are n-type, developing a p-type clathrate with high thermoelectric performance is an important issue. In this study, the electronic structure and thermoelectric properties of Ba8Cu6Ge40 clathrate are calculated based on density functional theory (DFT) to search for new p-type clathrates. An energy gap is formed in the electronic band structure of Ba8Cu6Ge40, and the Fermi energy lies in the valence band, indicating that Ba8Cu6Geぃis a p-type semiconductor. The effective mass of the valence
band is larger than that of the conduction band. The Seebeck coefficient for p-type is larger than that for n-type, reflecting the difference in effective mass. According to the dependence of Seebeck coefficient and electrical conductivity on the chemical potential, adjusting the Fermi energy, corresponding to the carrier concentration, to the optimum value improves the power factor. Therefore, the results of DFT calculation show that Ba8Cu6Ge40 has excellent properties as a candidate for p-type thermoelectric materials.

Since 2020, school education activities have changed significantly to prevent the spread of the ℃OVID-19". "Online lessons," which appeared in search of resumption of educational activities while avoiding the risk of infection, became more widespread and established than expected and exceeded the original purpose of "avoidance of Three Cs."
Anymore, it even shakes the significance of "face-to-face lessons" that have continued to exist as the most popular teaching method so far. Based on our interests, this paper aims to clarify the question, "How do students accept new learning forms such as online lessons and exchange of tasks via "Moodle", and how do they interpret them?".
Our university has already conducted a questionnaire about lessons for students, and statistical processing can give an objective evaluation of lessons. However, the questionnaire survey consists of data that cut out human perception at a particular time. It disregards the series of processes that human encounters an event, accepts, understands, leading up to recognition. Therefore, we conducted an interview survey of several university students and a qualitative analysis using Modified Grounded Theory Approach(M-GTA), clarifying the process of accepting this situation and building their learning.
In addition, we would like to identify the determinants that established the process of restructuring new learning and go beyond the binary opposition of "online or face-to-face" to deepen the essential understanding of lessons. We hope this knowledge will support learners'understanding of the COVID-19 pandemic and provide a new perspective to contribute to teaching methods studies.

There is a need to develop new energy sources that can replace or complement renewable energies such as solar power generation and wind power generation, which have been put into practical use but have many problems in terms of economy and stability. The author has focused on the SMFC (Sediment Microbial Fuel Cell) power generation research as one solution to this problem. In particular, the control of microorganisms that are the source of power generation was examined to increase the electrical output, which is the key to practical application. By incorporating an inorganic porous structure into the fuel cell, the author has succeeded in accumulating microorganisms near the electrode for the first time. As a result, it was found that the output characteristics of the SMFC were remarkably improved by inserting the porous material, which was embedded in the soil in advance and promoted the accumulation of microorganisms and organic substances, in the vicinity of the anode. By improving the open-circuit voltage and the short-circuit current, the output power has increased about 6 times on average compared to the conventional one. It is considered that the reason for this is that the accumulation of microorganisms near the anode promotes electron charge transfer into the electrode, increases the amount of generated hydrogen ions, and accelerates the reduction reaction. Furthermore, the author tried to optimize the amount and arrangement of the inorganic porous material to be inserted, and to introduce iron ions that have the function of promoting electron transfer in the battery. As a result, excellent output characteristics for practical use could be obtained.

Tungsten has a high melting point, low resistance, and excellent chemical resistance, and is used as an industrial material for lamp electrodes (filaments) and electrodes for large-scale integrated circuits. Since trace components in the material have a significant effect on the performance and reliability of the device, it is extremely important to determine the concentration of the components in order to evaluate the material properties. In this study, a separation and preconcentration method using a flow injection (FI) system has been developed for the analysis of trace elements in tungsten by AAS. A cation exchange resin column was used for separation and preconcentration. The spike and recovery tests of trace amounts of iron in tungsten were performed by the proposed FI system, and good recoveries were obtained without interference from the tungsten matrix. The proposed system has a 7-fold higher enrichment factor with a sample volume of 3.7 mL and a detection limit of 9 ppb (equivalent to 3.7 µ g g―1 in a solid sample), which enables highly sensitive analysis. The amount of waste fluid per sample analysis is extremely small (27 mL), and the relative standard deviation of 50 ppb iron solution measured five times repeatedly is 2.7 %, which enables accurate analysis. The system is capable of rapid analysis, taking only 6 minutes per sample, and the amount of liquid waste is less than one-tenth that of conventional method, thus reducing the burden on the environment. In this report, iron was selected as the target analyte, but this system is also expected to be applied to highly sensitive analysis of components that can be adsorbed on cation exchange resin.

This paper studies the Japanese translations of Lafcadio Hearn's "From the Diary of an English Teacher" and explores their role in highlighting the multilingual nature of the original text. "From the Diary of an English Teacher" (1894) is based on Hearn's experience as an English teacher in an ordinary middle school (Jinjo Chugakko) and in a normal school (Shihan Gakko) in Matsue. The essay is one of Hearn's most popular works and has been translated several times into Japanese. In his interactions with Japanese colleagues and students, he showed a strong interest in various types of Japanese, such as that used in the Japanese anthem "Kimigayo" or the Imperial Rescript on Education (Kyoiku Chokugo). Hearn sometimes transcribed these Japanese words using Roman characters, while at other times he translated them into English. This makes his writing difficult to translate into Japanese, and it becomes necessary to examine each translated word closely. Hearn also paid attention to the English compositions written by his students. These writings are also difficult to translate into Japanese and require special strategies. In this paper, we analyze the works of three translators of Hearn's essay: Ryuji Tanabe, Teiichi Hirai, and Sukehiro Hirakawa. Tanabe's version was published in 1926 and was included in the first collected works of Hearn in Japanese. Hirai's version was included in his translation of Hearn's works in 1964, which played an important role in making Hearn popular in Japan. Hirakawa's version, however, is the most accessible and widely read of the three.

In spite of vaccination on a large scale, COVID-19 has continued spreading all over the world. In the history of Japan many epidemics such as Smallpox and Tuberculosis have broken out and taken many people's lives. In this study, I research on the epidemic outbreak of Cholera which was raging throughout the Choshu domain in 1858. It happened after Japan was forced to open the country to the Western countries, and Cholera spread almost all over Japan from the crew of an American ship in Nagasaki port who was infected in China. The Cholera epidemic was one of the reasons for the expulsion of foreigners from Japan.
It was an age when neither vaccines.treatments.nor even original pathogens were known. How did the statesmen and people in the Choshu domain confront this terrible and unknown infectious disease? What did they leave as lessons for the future? In this study, I inquire into the following historical sources : One is the Ura Dairy written by Yukie Ura, an upper samurai.the Lord of Atsuki (a part of now Yanai) and one of the top political leaders of the Choshu domain. The other is the Furuya Douan Nichijou (Dairy) written by a doctor and educator living in a small village north of Shimonoseki at that time. The descriptions of the Cholera epidemic in the end of the Edo era give us useful hints about dealing with the challenges we face in our Reiwa period.

The Takahashi-Tanimoto identity-based solution in bosonic open string field theory contains one real parameter a. From various viewpoints, it has been confirmed that the solution is pure-gauge for a> -1/2 and represents the tachyon vacuum for a= -1/2. In particular, we have obtained a consistent numerical result with the above for the "double brane" solution in the previous work using the level truncation approximation. In the literature, we obtained the "double brane" solution in theory around the identity-based solution as follows: firstly, we constructed the "double brane" solution for various values of a at truncation level two, and then we constructed numerical solutions at each a level by level. Alternatively, at each truncation level, we can construct numerical solutions from Kudrna-Schnabl's "double brane" solution, which corresponds to the case a =O, by varying the value of a little by little. We have found that solutions by two methods are in different branches for a region of a at truncation levels 20 and 22. Here, we plot gauge invariants for them and give some comments on consistency.
