Sugarcane/bioethanol production and usage status in Brazil：As a case study of the Fernandopolis Aragaki Group in São Paulo State

南米調査ではサトウキビを栽培し、バイオエタノール生産を行っているフェルナンドポリスを中心に報告する。フェルナンドポリスは、サンパウルから600 ｋｍ離れた場所で、人口は約7 万人である。バイオエタノールを生産している沖縄の移民2 世で築き上げた新垣グループを訪れた。新垣グループで栽培するサトウキビ面積は33,000ha ～ 35,000ha である。沖縄県の2016 年度の13,000ha に対して2.7 倍に及んでおり、いかに広い面積であるか確認できる。 そして、サトウキビの生産量は、1 万トン/1 日（24 時間稼働）、年間約200 万トンを生産している。沖縄の85 万トン（2016 年）と比較すると約2.4 倍である。砂糖価格が高い時にはエタノールと砂糖生産を半々にして生産していたが、世界砂糖価格が下落した調査当時はエタノール100％を生産している。沖縄のように政府の補助金に頼らず、市場メカニズムの取り組みに成功している新垣グループの事例は日本の最大サトウキビ生産地の沖縄に示唆するところが大きい。technical repor

An Analysis of Junior High School English Textbooks: Focusing on Task Activities

The purpose of this study is to analyze junior high school English textbooks authorized by the Japanese Ministry of Education, focusing on task activities that help students have more opportunities to use English in classroom situations. Many researchers point out that task activities play a significant role in enhancing communicative ability by creating authentic meaningful situations. Since the Course of Study emphasizes offering opportunities for students to use English, these activities are being increasingly adopted in English textbooks. According to Matsumura (2020), there are six types of task activities: (1) jigsaw, (2) information gap, (3) problem-solving, (4) decision-making, (5) exchange of opinions, and (6) narration activities. This study classified task activities in textbooks into one of these six types. The results shows that the most used type is “exchange of opinions”, followed by “information gap”, while “jigsaw” and “narration” do not appear in any textbooks. Moreover, the features of textbooks are uniquely clarified in terms of the number and types of task activities. For instance, two textbooks use “information gap” activities even for the first graders whereas the others do not use them at all until third grade. It is important to note that various task activities would be possible even for the first graders if textbooks took a step-by-step approach in leading students to engage in task activities and to use more input-type activities.departmental bulletin pape

Archival studies of the "Documents of Hanashiro Family" held by the Kin Town Board of Education-Focusing on research, donations, cataloging, and the social significance of family documents-

コロナ禍における「花城家文書」の受贈・整理・公開のありようについて論じた。また、「花城家文書」が作成・収受・保管された要因や背景などを射程に入れながら文書群の構造分析に基づいた目録の編成・記述の方法について明らかにした。そのうえで、家文書・個人文書が、多少なりとも、国民や地域住民の「知る権利」の保障と、記憶の継承に関係することについて言及した。The paper describes the donation, organization, and public release of the Documents of Hanashiro Family during the COVID-19 pandemic. It will also explain how the catalog was compiled and written based on a structural analysis of the documents. It will also mention that family and personal documents are, to some extent, related to guaranteeing the "right to know" of citizens and local residents, and to the inheriting theirmemories.departmental bulletin pape
