楽曲から抽出した遷移確率を用いて旋律部分と伴奏部分を自動作曲する方法を提案する.遷移確率とは,音高,音長について,ある音高 (音長) のつぎに,どのような音高 (音長) が続くかの確率である.本稿では,実際の楽曲 (アーティスト:バンプオブチキン,ラルクアンシエル) から遷移確率を抽出した.アンケート調査の結果,音楽的に悪くなく,アーティストらしい曲が作曲できている事が確認できた.

Recently, many and various microbial products appear on the market. However, almost all of them could not have sufficient effects. The expectation of users to microbial products is rising up. It is because of the directions for the environmental friendly and sustainable industrial activity. In addition, it is expected that the development of genetic engineering can make the possibility for the practical use of potential ability of microbes which is still not known.There are two major problems in practical use of microbial products. First, the transplanting of microbes into the target environment is not easy. Because, many indigenous microbes are inhabit in the industrial field and they doesn't allow introduced microbe(s) to be dominant in the field. Moreover, the environment of target fields is very fickle for introduced microbes. Second, the insufficient information of products promotes the misunderstanding to the users for the effect of the products.To the practical use of microbial products in the industrial fields, the researches and developments of reliable and effective products are required. Thereby, the preparations of special feeding and habitat are important for introduced microbes. Moreover, the analyses of microbes transplanted in the industrial fields are important to guarantee both the quality of the products and the correct information to users.The purpose of this communication is the clarification of present challenge for the practical use of microbial products in the industrial fields. Then, this communication suggests the several ways for the research and development of reliable microbial products and useful analytical methods for microbial community by genetic engineering.
