Abstract

Elucidating the sealing capacity of caprock is very important because CO2 sequestered in deep aquifers can remain there for several hundred years in the CO2 sequestration. Threshold capillary pressure is a key property affecting sealing capacity, and therefore, the ability to measure the threshold pressure of a target rock conveniently is highly sought after. In this study, data collected during the CO2 injection process in triaxial compression tests of mudstone supposed to be a caprock were used to measure threshold pressure via the dynamic method. These triaxial tests were conducted to study the mechanical properties of mudstone below depths of 1000 m. The threshold pressure for 23 out of 26 test samples was successfully measured. Measured values ranged from 0.54 to 1.57 MPa, which was within a reasonable range compared to the results reported by three other studies that used similar mudstone specimens. A small amount of shrinkage induced by a pore pressure decrease, which was caused by a threshold pressure, was observed in the experiment. The threshold pressure showed a positive correlation with the shrinkage, implying that this pressure might be estimated from the shrinkage. Thus, a volumetric elastic constant was calculated from the shrinkage assuming that the decrease in mean pore pressure was half of the threshold pressure. The mean volumetric elastic constant was 0.92 GPa, which was about 40% lower than that of the rocks from which the test samples were obtained. These results indicate that the shrinkage value cannot be directly used to estimate the threshold pressure, and that a correction of this shrinkage value is necessary.

Abstract

Weld-joint has been atracting attention to assemble structures of dissimilar metals, particularly in automobile industry. However, the application of weld-joint to steel and aluminum plates is still limited due to uncertainty of the fatigue strength. Fatigue strength of weld-joint is rather complicated to evaluate because both effects of stress concentration at the edge and formation of intermetallic compounds along the interface should be considered carefully. This study focused on finding the key factor that determines the fatigue strength of steel-aluminum brazing joint by considering the variation of strength along interface. The welded part of single lap joint was partially removed by a wire-cut electric discharge machine to investigate the influence of length and location of interface on fatigue strength. When the applied load was relatively low it was found that the numbers of cycles to failure were found to be similar, even though the lengths of interface were different due to partial removal. Furthermore, observation on the fracture surface indicated that early stage of crack propagation showed similar topography regardless of the partial removal of weld part. These results clarified that the number of cycles to failure was mainly consumed at the early stage. Finite element analysis was then conducted to investigate the stress component affecting the fatigue strength. As a result, principal stresses were maximum at the fracture initiation site in all the specimens. Therefore, we concluded that fatigue life of weld-joint is dominant in the early stage of crack propagation, which is characterized by the principal stress.

Abstract

To improve the high-temperature oxidation resistance of grade S45C carbon steel, we formed a Cr / Ni diffusion layer on the surface of carbon steel by atmospheric-controlled induction heating fine particle peening (AIH-FPP) treatment. Cr and Ni particles were mechanically milled in planetary ball mills and used as shot particles in the AIH-FPP treatment to create a Cr / Ni diffusion layer. High temperature oxidation tests were carried out at 900°C for 100 hours to evaluate the high-temperature oxidation resistance of the AIH-FPP treated specimen. The mechanically milled particles and specimen were analyzed using a scanning electron microscope, an energy dispersive X-ray spectrometer, and an X-ray diffractometer. Results show that the AIH-FPP treated specimen prepared using mechanically milled particles formed a Cr / Ni diffusion layer on the carbon steel. The carbon steel sample with the Cr / Ni diffusion layer exhibited improved high-temperature oxidation resistance compared to the untreated sample. This is due to the formation of Cr and Ni oxidized layers on the treated surface, which inhibited oxidation of the inner substrate. The results indicate that a Cr / Ni diffusion layer formed by AIH-FPP treatment using mechanically milled particles can improve the high-temperature oxidation resistance of grade S45C carbon steel.

Abstract

This paper reports on the overseas teaching practicum in the U.S. and the international forum in which we exchanged ideas on “next-generation global teacher education.” This year, four graduate school students participated in the overseas teaching practicum, and we found the change of their lessons from “information-giving” style in the previous years to “experiencing”, “exchanging”, and “creating” type of lessons this year. The participants reported that it became an excellent opportunity for them to consider a better and comprehensible way to explain something to children since there was “the English barrier”, they noticed the power of visual and other means to convey messages. In the international forum, held earlier in July in Hiroshima, two participants of the previous year’s overseas teaching practicum program reported how their perspectives toward education and the actual lessons had been changed from the experience. The speakers from the U.S. introduced how international exchange at their schools work to broaden the students’ eyes and their global-mind.

21. Globalization and Reconstruction of Social Policy: A Japanese Case Study

Author

Fukazawa, Kazuhiro

Abstract

This paper examines why Japanese social policy changed from the 1990s. Globalization and its accompanying trade liberalization have affected the regime of international political economy and social policies of many countries. Many previous studies on this issue focus on the U.S. or the U.K.; however, the Japanese social policy system is different from that of those countries because the roles of the companies are very important. In the 1990s and the first half of the 2000s, Japanese social policy experienced neoliberal reform due to the reaction to globalization. Japanese neoliberal reform is mainly diversification of employment types and reduction of welfare programs provided by companies. However, because of this reform, two problems have arisen. One is the increasing number of non-regular employees, and the other is a lack of social security. To solve these problems, Japan reconstructed the social policy system in the second half of the 2000s and the 2010s. This paper assumes three paths to resolving problems after neoliberal reform. Path A is reconstructing the social policy. Path B is continuing with neoliberal reform. Path C is denying globalization and encouraging protectionism. According to the result of analysis, Japan has chosen path A among these paths.

Abstract

In recent years, bank breaching occurred high frequency. In August 2016, the east pan of Hokkaido in Japan was attacked a heavy rainfall and the tributaries of Tokoro River (Shibayarnasawa River and Toua River) had a bank breach caused by the back water of Tokoro River. Although both tributaries were almost the same size and both junctions were very close, the situation of inundation were largely different. At the breaching point of the Sibayarnasawa River, the inundated flow toward to the upstream side of the inland, while at the Toua River it was perpendicular to the channel. In order to understand the cause of the difference in phenomena, it was tried to reproduce the breaching situation in both tributaries using the numerical simulation model “iRIC Nays 2D Breach”. From the result, it was revealed that the direction of the inundated flow changes greatly depending on the timing of the discharge change at the tributaly when the bank failure occurs. At the time of bank breaching, when the discharge of the tributary is small, the inundated flow towards to the upstream direction. At the time of bank breaching, when the discharge of the tributary is large, the inundated flow towards to the perpendicular direction of the channel.

Abstract

The purpose of this study is to identify features of teacher-student interaction in senior high school English classrooms in Japan. In recent second language acquisition research, many studies have been carried out on corrective feedback to L2 learners’ oral and written errors. However, although classroom interactions include far more diverse interactions including error corrections, few studies have analyzed how meaningful and communicative those interactions are. Therefore, the present study chose two 50-minutes English lessons by two experienced high school teachers, extracted from their lessons a total of 85 units of teacher-student/ student-to-student interactions in English/Japanese and closely scrutinized them for common classroom communication patterns among Japanese teachers of English. The results indicated that the analyzed classroom interactions contained many teacher-dominated one-way interactions both in English and Japanese.

Abstract

本共同研究の目的は，学校教師が，専門科学（研究）者が行う研究を教材研究として読み解き，その読み解きから一人の研究者の「学習」過程を読み取り，授業づくりに応用する，論文読解から学習構造への変換システムを開発することにある。 本稿では，小学校における教科横断型単元を開発するために，社会科と英語科が協働して進めるCLIL（Content and Language Integrated Learning : 内容言語統合型学習）単元を事例に取り上げる。社会科と英語科の教員がフロイド＝シュモーの活動を共通事例に，それぞれの教科授業を構想し，協働した単元を作るために，共通の教材研究として用いた論文（著書）読解を研究対象とした。ここではシュモーに学ぶ会編『ヒロシマの家－フロイド＝シュモーと仲間たち－』の読解から，専門科学（研究）者の「真正な学び」を学習者の学びへと変換する過程と，その構造を解明した。そのうえで，小学校社会科・英語科が協働するCLIL 単元を開発し，その開発過程を説明した。この教材研究からCLIL 単元作りへの過程をどのように進めたのかを明らかにすることを通して，教科横断型単元開発における，著書読解，その教材研究，単元づくりという教師の学びのプロセスを明らかにした。 明らかにした点は，次の3 点である。 （１）小学校段階においても，またその教科横断型単元開発でも，論文（著書）読解による研究者の学びの構造理解は教材研究－単元づくりの過程に有効に活用することができる。 （２）小学校段階では，単元づくりにおいて，論文（著書）読解で見いだした研究者の学びの構造は応用・活用できるが，発達段階，学習環境に応じて別のものに変えた方がよい場合がある。教科横断型単元では2つの教科における学習双方に有効な材料を見いだすことが戦略上，大切である。 （３）教材研究としての論文（著書）読解において重要なことは， １）その論文（著書）の構成に示されている構造の発見である。 ２）その構造が示す中心観念である。そして，その中心観念が単元づくりの中心に活用できるかどうかを検討することである。 ３）小学校の教材研究と単元づくりでは，発達段階や子どもの学習における適切性である。, The purpose of this collaborative study is to design a transformation system in which school teachers read academic literature as a way of materials study; they learn a researcher’s learning process by reading his/her research articles/books; and they apply their findings to lesson planning. In particular, the present study focuses on a lesson for Content and Language Integrated Learning (CLIL) collaboratively developed by social studies and English teachers in order to carry out cross-curricular lesson planning at the elementary school level. First, a social studies teacher and an English teacher individually planned a lesson based on the activities by Floyd Wilfred Schmoe as a common case and later studied a book about his work as a common ground for collaborative materials development. Here they read the book about Schmoe’s Houses for Hiroshima Projects and learned the process and structure of how to turn professional researchers’ learning to learners’ learning. Then the authors developed a CLIL lesson together and showed its design process. This materials development study shows the process of CLIL lesson planning and by doing so, it showed a teachers’ learning process in cross-curricular lesson planning ranging from reading articles/books, materials study, and lesson planning. There are three findings from this study: (1) Understanding the structure of researchers’ learning process can be utilized in the process of materials study and lesson planning in cross-curricular lesson planning in the elementary school. (2) Although it is possible to apply and use the structure of researchers’ learning found in their articles/books, findings should be adapted to the children’s developmental stages and learning environment. It is important to make sure that the developed cross-curricular lesson should provide effective materials to both subjects. (3) Important things in reading articles/books as materials study are: 1) to identify the structure of the target articles/books 2) to identify the key concepts of the resource materials and see if those concepts can be used as a core in lesson planning 3) to consider if the developed materials/lessons are appropriate for children in elementary school, ※内容訂正のためPDFファイル差替え（2017年7月18日）
