However, the exact meaning of the word is ambiguous and inconsistence. Hence, this study aim to clarify the meaning of “the environment” qualitatively and quantitatively, by investigating and analyzing sixty-seven textbooks of the environment. As a result, main elements of “the environment” are listed by the extraction of the textbook contents and divided into eleven fields. In addition, the proportion of each field varies among the textbooks and is visualized by boxplot with all of the textbooks, indicating that “pollution” and “climate system” are large proportion. These results help us to understand “the environment” and to develop the environmental studies. キーワード:「環境」,書籍分析,環境学,定量化","PeriodicalId":113122,"journal":{"name":"Ningen to kankyo","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122891676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined how anthocyanin pigment, an antioxidative substance, changes under salt stress conditions and how the antioxidant properties of this pigment affect the salt resistance reaction in perilla ( Perilla frutescens ) plants. The results indicated that the salt tolerance of anthocyanin-rich red perilla plants was higher than that of anthocyanin-poor blue perilla plants. The maintenance of ion homeostasis, which corresponds to ionic or osmotic damage, was not the main function of anthocyanin. Instead, the pigment exhibited a secondary radical oxygen scavenging function. Specifically, the primary salt tolerance function of red perilla was associated with the antioxidant ability of anthocyanin, and the content of this antioxidative pigment nearly doubled as salt stress increased. Moreover, the antioxidant functions of active oxygen scavenging enzymes, mainly catalase, were subsequently detected. In conclusion, the results indicated that increasing amounts of anthocyanin pigment under salt","PeriodicalId":113122,"journal":{"name":"Ningen to kankyo","volume":"342 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122545144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
