Kyodo Gyogyo Fisheries Company developed into the biggest fishing company in Japan, owning 71.6% of trawlers in the 1930s. It decided to expand into shrimp trawling off the west coast of Mexico in 1934. Since 1929, the soga shosha Mitsui Bussan had imported Galveston shrimp, caught in the Gulf of Mexico, in the United States. Shrimps were a profitable business, and Mitsui expanded its business to the Gulf of California and bought large quantities of shrimp from Mexican cooperatives at Guaymas. Kyodo's trawlers also used Guaymas as a fishing base and came into conflict with Mitsui. But in February 1937, the two companies launched a US$19, 000 joint venture called the Guaymas Project. The venture failed after half a year when Mitsui withdrew, fearing no future in the importing of shrimp because of strict foreign exchange controls by the Japanese Ministry of Finance.In September 1937, Nippon Suisan's Mexican office asked the San Francisco office of the soga shosha Mitsubishi Shoji to sell its shrimp and provide financial assistance. Their relationship was good, but with increased sales in the United States, Kyodo, renamed Nippon Suisan in 1937, depended more and more on Mitsubishi for both sales and finances. Mitsubishi gradually left the sales business in the hands of American brokers, while taking a 5% commission but providing insufficient financial support. In July 1940, Nippon Suisan sought to restructure its Los Angeles office to sell directly to American brokers on the West Coast and dismantle the sales system dependent on Mitsubishi. But until September 1940, Mitsubishi continued to control 100% of sales of two fisheries companies, Nippon Suisan and the late-coming Hayashikane Shoten. The trawling of shrimp was prohibited by the Mexican government in September 1940, a move supported by popular nationalist sentiment in Mexico.

本研究では,探究活動を行う高校生80名に対して質問紙調査と「振り返りメモ」の分析を行い,探究活動の前後における「科学の本質(Nature of Science: NOS)」に対する理解の変化を明らかにした。これにより以下の三点が明らかになった。第一に,選択式質問項目の分析結果から,自然科学の探究活動を行う生徒においては「暫定性」,人文社会科学の探究活動を行う生徒においては「理論負荷性」に対する理解に深まりが見られた。第二に,探究活動を通じて「暫定性」や「理論負荷性」に対する理解に深まりが見られた生徒の「振り返りメモ」の分析から,探究活動の中でも特に先行研究を検討する過程においてNOSに対する理解が深まることが示唆された。第三に,自然科学や人文社会科学といった探究する領域の違いや指導形態の違いによってNOSの理解の仕方に相違が生じる可能性が示唆された。以上より,探究活動を通じてNOSに対する理解が深まることが明らかになった。これらを踏まえ,探究活動が今後日本におけるNOS教授の足がかりとなる可能性を指摘した。

一側性難聴児は対側が正常聴力であれば,乳幼児期の言語獲得や日常生活において支障はないと考えられてきた。しかし,両耳聴ができないために,騒音下での聞き取りが困難,難聴側からの聞き取りが困難,音源定位が困難である。特に学童期になると,集団学習の場である学校の教室は暗騒音や他の児の声などの騒音があることから,一側性難聴児にとって教室は教師の声が聞き取りにくい環境であると考えられる。これまで本邦では,一側性難聴児の座席配置を教室の前方で聞こえる方の耳を教師に向ける席が望ましいと指導する程度で,それで十分な聞き取りができるかの検討は行われてこなかった。我々は,一側性難聴児の騒音下での語音聴取能を評価し,学校での聴覚補償として,一側性難聴児の補聴援助システムの使用とその購入費助成制度について報告した。

小児,思春期,若年のがんにおいて,造血器腫瘍の占める割合は多い。治療成績の向上により長期サバイバーのquality of lifeへの関心が高まっている中,治療後の妊孕性低下は重要な問題である。近年,国内外より妊孕性ガイドラインが発表されており,以前に比べて各治療レジメンの妊孕性低下リスクや妊孕性温存療法に関する情報が入手しやすくなった。一方,妊孕性温存に充てる時間が極めて限られる造血器腫瘍において,妊孕性温存療法は実施可能なのか,温存ができた場合に将来挙児が得られる可能性はどれくらいか,などの情報は不足している。さらに,妊孕性低下リスクの不明な新規薬剤を使用する場合には妊孕性温存療法を実施すべきかなど,未解決の問題が多く残されている。

The aim of this study is to investigate myocardial damage in recovering coronavirus disease 2019 (COVID-19) patients with high-sensitivity troponin levels (hsTnT) and echocardiography. In this single-center cohort study, 215 COVID-19 recovered patients were recruited from all over Japan between April and September 2020. Demographic characteristics, hsTnT levels, and echocardiography data were collected for 209 patients, after excluding those without serum samples or good-quality echocardiographic images. The mean (± standard deviation) age was 44 (± 12) years (range: 36-55 years), and 50.7% of the patients were males. The median time interval (interquartile range) from COVID-19 onset to post-recovery examination was 56 days (34-96 days). Seventy-four recovered patients (35.4%) had hsTnT less than detection sensitivity (< 3 pg/mL) and 135 recovered patients (64.6%) had hsTnT ≥ 3 pg/mL. Ejection fraction was more than 50% in all cases. Left ventricular global longitudinal strain (LVGLS) and right ventricular free-wall longitudinal strain (RVFWLS) were reduced in 62 (29.7%) and 8 patients (3.8%), respectively. They were significantly associated with elevated hsTnT levels. In cases with hsTnT above 5 pg/mL, the LVGLS was greatly reduced to 19.0 ± 2.2% (p < 0.001). Multivariate linear regression analysis showed that elevated hsTnT level was an independent predictor of reduced LVGLS (standardized β = -0.34; p < 0.001). In recovered COVID-19 patients, even a slight increase in hsTnT above detection sensitivity was associated with decreased LVGLS. hsTnT and echocardiography may be useful tools to detect myocardial injury in recovered COVID-19 patients.

The half-century's effort to increase food supply has not solved the world food problems, and “Zero Hunger” remains to be the second goal of the Sustainable Development Goals. This paper aims to suggest a theoretical framework to analyze food and agriculture that are embedded in the capitalist world economy. It first reviews research trends of the capital appropriation of agriculture, agri-food business analysis, and the Food Regime frameworks, as well as the recent discussions on the financialisation of food and agriculture. Then, the paper discusses the historical case of Japan by positioning it in the Food Regime frameworks; how Japan's modern food system has developed along its capitalist development since the 19th century. It reveals the policy decisions of Japan's modern nation state and its effort to accumulate capital, together with large Japanese capital of Zaibatsu (the origins of some sogo-shosha), contributed to build modern industries of flour-milling, vegetable oil refining, and sugar manufacturing. As Japan opened its market in the middle of the 19th century, it began importing wheat flour, which had become a world commodity in the First Food Regime. Japan itself contributed to promote soy as a world commodity in the First Food Regime in the Asian context. Then, Japan established modern sugar industry based on its colonial crop in Taiwan. After WW2, these industries, together with sogo-shosha, incorporated Japan's food system into the US-centred agri-food complexes in the Second Food Regime. In the current Global Corporate Food Regime, Japan's sogo-shosha and large food-related companies have been expanding their business abroad, especially to the growing economies of Asia. In conclusion, the theoretical frameworks for the capitalist food system are necessary to analyze the world food issues, as our food and agriculture have been deeply embedded into the capitalist power relations.
