Comparison of biliary tract cancer incidence and rice yield by age group and prefecture
Get PDF胆道癌は早期発見と治療が困難で、予防が重要な疾患である。罹患率には地域差があり、日本はリスクの高い国の一つで、特に東北地方に多い傾向がある。リスクとして、遺伝子多型、胆石などの疾患、脂肪摂取過剰などの栄養学的因子に加えて、化学物質などの環境因子があげられる。先行研究では、稲作に関連した除草剤と罹患率・死亡率との関連が示唆されている。本研究では、コメ収穫量の多い10 道県について年齢階級別罹患率と収穫量との相関関係を調べ、胆道癌と稲作との関連について検討した。その結果、人口10 万人あたりのコメ収穫量と胆道癌罹患率との間には正の相関があり、更にこの相関には加齢に伴ってより強い影響が見られることが分かった。この年齢依存的影響について、1970 年代の農薬大量散布が主要な有害因子で、当時20 － 30 歳代の人への影響が50 年後に現れたと考えると説明できる。その場合、今後10-20 年で強い相関は次第に消失すると予想される。一方多くの有害因子総量が問題なのであれば、環境改善により罹患率が下がっても年齢依存的影響は存続すると予想される。今後は、低農薬・無農薬への取り組みについて、疫学的観点から注目してゆきたい。Biliary tract cancer is difficult to detect and treat at an early stage; thus, its prevention is important. Regional differences exist in disease incidence, and Japan is one of the highest-risk countries, particularly Tohoku. In addition to genetic polymorphisms, diseases such as gallstones, nutritional excess of fat, and environmental factors such as chemical substances are listed as risk factors for high incidence. Previous studies have suggested a relationship between herbicides used in rice cultivation and morbidity and mortality. In the present study, we examined the correlations between incidence rates by age group and rice yields in ten prefectures with high yields and discussed the relationship between biliary tract cancer and rice cultivation. Positive correlations between rice yield per 100,000 individuals and cancer incidence rates were observed, which were influenced more strongly by aging. This age-dependent effect can be explained by the fact that the mass spraying of pesticides in the 1970s was the main harmful factor and that the effect on individuals aged >20 and >30 years appeared 50 years later. In this case, the strong correlation in older individuals can be expected to gradually dissipate over the next 10–20 years. However, if the total number of adverse factors were a problem, the age-dependent effect would remain to some degree depending on environmental improvement. It can be concluded that efforts should be carefully implemented to reduce or eliminate pesticide use from an epidemiological perspective.departmental bulletin pape

What Can Language Teachers Learn from Bilingual Children?
Get PDFThis article seeks to explore the question “What can language educators learn from bilingual children?” First, an earlier study, based on a survey of children who grew up using both English and Japanese, is described. An analysis of the survey yielded seven principles that respondents identified as essential in their becoming bilingual. These principles are used as a framework for assessing the authors’ university English-language teaching practices. The article concludes with some practical suggestions for teaching ideas based on the experiences of and suggestions from bilingual children.departmental bulletin pape
