The Research on the Usage of Roman Letters of ISHIKAWA Takuboku's "Romaji Nikki".

本研究以石川拓北的《罗马字日记》为研究对象，对该书的罗马字母用法进行了研究，并得出以下结论：1.《罗马字日记》的机读教材的编写对于《罗马字日记》，研究者对罗马字母的用法往往漠不关心。这可能是我们没有紧跟原作的印刷型书的原因之一。然后，我访问了函馆，在那里“罗马吉尼基”是保管的函馆市图书馆。在图书馆和函馆市文学馆，我阅读了原文的副本，然后我编写了一本机读教科书，它尽可能地遵循原文。2.对《罗马字日记》罗马字母用法的分析通过对机读教科书的调查，我证实了它是按照日本系统还是赫普本系统分为四个部分。在第二部分和第三部分之间，插入了一个名为“Kokuon Romaji-ho Ryakkai”的罗马字母表，它有两个显著的特点。一个是关于缩音，另一个是“独立音标”（[overhead dot][overhead dot]）。后者在《罗马日记》中实际上使用了两次。3.在罗马文字史上定位拓本的使用特征我在国立国会图书馆进行了研究，发现这两个特征都有先例。关于前者，我找到了末松贤长和丸山敬一的著作，关于后者，我找到了南武义一的著作。关于2和3，我在2004年日本学术会秋季会议（熊本大学）上阅读了一篇论文，并为“日语研究”做了贡献。

On this research, I have investigated the usage of Roman letters of ISHIKAWA Takuboku's "Romaji Nikki" and obtained the result below.1.Compilation of a machine-readable textbook of "Romaji Nikki"As for "Romaji Nikki", researchers tend to be indifferent toward the usage of Roman lettters. It may be one of the causes that we have no printing type book closely following the original. Then, I visited Hakodate, where "Romaji Nikki" is in custody of Hakodate City Library. At the Library and the Hakodate city literature museum, I read the copy of original, and then I drew up a machine-readable textbook, which follows the original as closely as possible.2.The analysis of the usage of Roman letters of "Romaji Nikki".Investigating the machine-readable textbook, I verified it is divided into 4 parts by that which Takuboku wrote with, Japan system or Hepburn system. Between the 2nd part and the 3rd, a table of Roman letters, named "Kokuon Romaji-ho Ryakkai", was inserted, and it has two distinctive features. One concerns the contracted sound, and the another is the "independent pronunciation mark" (【overhead dot】【overhead dot】). The latter was actually used twice in "Romaji Nikki".3.Positioning the features of Takuboku's usage in the Roman letter historyI researched at the National Diet Library, and found the two features have previous instances. For the former, I found SUEMATSU Kencho's and MARUYAMA Michikazu's, and for the latter, NAMBU Yoshikazu's.As for 2 and 3, I read a paper at the Japanese Academic Society Fall Conference in 2004 (at Kumamoto University), and contributed to "Studies in the Japanese Language".
