    • 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.

    • Chromium has diverse oxidation states, the charges of +3 and +6 for chromium occur the most commonly within chromium compounds. Trivalent chromium (Cr(III)) is not toxic and is essential for living organisms. On the other hand, hexavalent chromium (Cr(VI)) is known to has the strong ability to oxidize and to be a carcinogen. Therefore, it is important selectively to determine of Cr(VI) for the analysis of chromium due to the difference of toxicity between Cr(III) and Cr(VI). 1, 5-Diphenylcarbazide (DPC) is a reagent which selectively reacts with Cr(VI) to color violet complex. We have developed a simple and sensitive analysis of Cr (VI) using a micro fluidic paper-based analytical device (μPAD) with the DPC colorimetric reaction. The fabrication of μPADs was carried out by melting wax with an oven after the pattern was printed with a wax printer. The detection spots were dropped DPC solution and dried. Then, the sample solution was dropped into the sampling spot and wicked to the detection spots. μPAD was scanned with a scanner, the color intensity for the detection spots was analyzed by an image analysis software. The RGB intensity of the images was analyzed, and the highest sensitivity was obtained when G-intensity was used. The detection limit of this device for the Cr(VI) analysis was 26.2 μg/L, the sensitivity for present method has been enhanced compared to the previous method (30 mg/L).

    • Recently, nanostructured materials or nanocomposites, rather than thin films or superlattices, are of increasing interest in creating a new material with high thermoelectric figure of merit. The approach of nanoscale control of materials by introducing nanostructures, such as nanoinclusions, nanointerfaces, etc., may have a significant influence on the transport properties due to the energy filtering effect of the potential barrier at interfaces, or strong scattering effect of phonons and/or carriers at interfaces, whose density increases with decreasing size of structure. On the other hand, it is also of importance to elucidate the mechanism of enhancement in the Seebeck coefficient for nanostructured material systems. The density functional theory (DFT) using non-equilibrium Green’s function (NEGF) method may be a powerful tool to calculate the transport properties of nanoscale systems. There are, however, few studies of nanoscale system for thermoelectric clathrates by DFT using NEGF method. Thus, we adopt the DFT using NEGF method to calculate the transport properties of nanoscale system of Ba8Au6Si40/nanogap/Ba8Au6Si40, where nanogap acts as a potential barrier, as a model of nanoscale clathrate Ba8Au6Si40 system, to investigate the effect of nanointerface on the transport properties of thermoelectric clathrates. For Ba8Au6Si40/nanogap/Ba8Au6Si40 system, the Seebeck coefficient value at EF is greatly enhanced. The electrostatic potential difference was found to be large at the nanogap for Ba8Au6Si40/nanogap/Ba8Au6Si40 system. The calculation suggests that the potential barriers at nanointerface, such as grain boundary, have a significant influence on the Seebeck coefficient. We also discuss the effect of nanointerface on the electron and thermal conductance.

    • 「デイジー・ミラー」は、ヘンリー・ジェイムズの最も広く読まれ、研究された作品の1 つといえるだろう。この小説は、当時人気のあった旅行物語であると同時に、「国際テーマ」を取り上げた作品の嚆矢と見なされている。モダニティの観点から、この小説はさまざまな解釈の可能性を持って再読する価値があるといえる。いくつか例を挙げると、登場人物は単純化されており、より深い解釈が必要である。ヒロインの弟は、ほぼすべてのもの、人物に対しアメリカがベストという発言を繰り返し、現在のアメリカ第一主義を髣髴とさせる。アメリカン・マネーの経済力は Daisy が欲しいものを手に入れる手段として、物語の中で繰り返されているが、その源である父親については息子や妻によって言及されるだけで、経済力としての存在としてしか扱われていない。アメリカ・ドルの力は今でも世界中で支配的な力を持っていることを再考慮する必要がある。
       ヒロインの Daisy は「アメリカの浮気娘」として単純化されており、彼女は物語を通してヒーローの Winterbourne を当惑させている。 Winterbourne は、女性の美しさを「観察および分析することに夢中になっている」ため、Daisy の闊達な自発性に不思議の念を感じずにいられない。この2 人の人物造型や関係性は、従来とは異なる視点から解釈することが可能である。
       この論文では、この古典的な物語に新たにアクセスし、モダニティの観点から解釈したいと考えている。ここでのモダニティの観点とは、男性と女性の主人公の関係、経済力、市場の拡大、商品化された文化などである。さらに、都市小説, 紀行小説としての側面についても言及していく。

    • The activities of preventive care are important for extending life expectancy and improving the quality of life in an aging society. In order to spread these activities, the role of the community is important. “Ikiiki Hyakusai Taiso,” meaning lively 100-year-old’s gymnastics, is one of the preventive care activities operated by a local community. We analyzed whether there are any differences in the 12 elementary school districts regarding the data on living functions, physical functions, and medical expenses of the participants of the Ikiiki Hyakusai Taiso held in Sanyo-Onoda city. As a result, the Koyo Elementary School district was characterized by a few seconds of standing on one leg with eyes open, and low medical expenses. The community of Koyo Elementary School district has strong ties, and it is thought that preventive care activities are progressing with the help of local people. Akazaki and Motoyama Elementary School districts tend to have a high degree of certifications for preventive care. It is thought that this is because people who serve as self-government chairpersons and civil welfare officers and have a sense of mission play a central role in preventive care activities, and even those who find it difficult to participate alone in gymnastics can participate. It is important to strengthen local ties as a way of promoting preventive care activities. In areas where regional ties are not strong, it is considered effective to involve the chairman of the autonomy and local welfare officers.

    • Focusing on questioning skills as a component of critical thinking, this study examined a common classroom practice for developing these skills in students: comment cards. The purpose of this study was to develop a questionnaire that measures the effectiveness of comment cards by describing how students use them and what ideas and attitudes they foster among students.
       A survey was conducted with 108 participants, making use of 15 question items regarding how teachers intended to use comment cards in classes and how the students responded. A factor analysis yielded 11 items divided into three factors . After testing the reliability of the model, a final version of the scale (the Scale for Measuring Effectiveness of Comment Cards) was produced.
       The scale can provide researchers with a quantitative measure for examining the practical effectiveness of comment cards. When used in combination with scales on critical thinking and questioning, the scale can further provide insights into both the practical effectiveness of comment cards and the issues to be addressed.

    • 我が国の教育機関として、江戸時代には、藩校をはじめ、全国各地に多くの郷校(郷学)、寺子屋、私塾等が存在していた。中でも、郷校は全国で108校あったが、防長(周防・長門:山口県)で19校あり、校数で全国1位の数であった。その意味においても、山口県には域内各地で教育文化が根付く土壌があったと言える。山口県で育まれた特徴的な教育文化や道徳文化を語る上で、非常に有効であると思われるものについて、(1) 吉田松陰の行動力、(2) 郷校「徳修館」の存在、(3) 金子みすゞの詩、などを挙げることができる。これらの内容と、今後の教育課程改革に繋がる理念について、本論文で明確にしたい。吉田松陰が主宰した松下村塾では、最近告示された新しい学習指導要領の中で強調されている「主体的・対話的で深い学び」に繋がる教育が日常的に展開されていた。熊毛の地にあった郷校「徳修館」では、最近の学習指導要領の中で強調されている「生きる力」を形成する「知・徳・体」の3本柱の立体構造性・順序性の教育理念が貫かれていた。天才的童謡詩人である金子みすゞの詩の中には、仏教的な理念に裏打ちされた東洋的な発想が基盤にあり、今後の教育や科学を語る上で有効である。これらの中には、初等中等教育において順次、実施が始まっている新しい学習指導要領の教育理念と本質的に合致するものがある。山口県の教育文化と今後の教育課程改革の理念を関連づけて考えようとしたことが、本論文を作成した動因である。

    • Immediately after the Great East Japan Earthquake, I arrived at the university and started research on renewable energy that is resistant to natural disasters. For 10 years, I continued my research with my dear students in areas where other researchers have not done much. Among them, I would like to introduce three technologies that I have a strong feeling for. We have developed a transparent solar cell that converts ultraviolet rays into electric power, including its formation technology, and achieved the world's highest level of efficiency. It was possible to show that wind power generation with a diffuser using the wind lens effect can generate power even in weak winds. Furthermore, the soil microbial fuel cell originating from microorganisms has achieved 10 times the conventional power generation by introducing the novel porous body, which is our invention, and is close to practical use. This area has long daylight hours due to the coast of the Seto Inland Sea, and although it is weak, the wind always blows, and there are many lakes and rice fields. We would like to receive natural energy from them and convert it into electric power, which will lead to the realization of local production for local consumption of energy.
