About my family name
Before 19 October 2003 when I got married, my family name was "Tanaka". Therefore all the publications in which I was involved and written in English are under the name of "Takehiko Tanaka".
Domestically, all the applied patents are in the name of "Murakawa", and you could find my current family name in several verbal presentations and proceedings of workshops.
Since 2007, I write papers with "Takehiko Murakawa" as the author's name.

Foreign Student Guidance
For about a half year from September 2005, I took in a French student, Mr. Martin Rolland, through the exchange program between University of Technology of Belfort Montbeliard in France and Wakayama University. I provided images of Buddhist canons and some research problems while he wrote several Java programs for the image process. We communicate in English, but I think it worked well since he had full patience as well as excellent linguistic ability. Moreover, he enjoyed communication with lab mates in English and in Japanese, which stimulated the whole laboratory.
Since 2004, one or two Chinese students per year joined our laboratory, so we teaching staffs have given continuous guidance. Some of them had been research students of Graduate School of System Engineering to pass the entrance examination for postgraduate course. We communicate in Japanese, and they write documents and make presentations in Japanese, although I often get the word in Chinese when they talk with each other.
Computing Environment
I use several desktop PCs and laptop PCs for servers and end-user computing.
The server computers have Linux (Ubuntu or Debian) installed. It is rare that I directly login such a server, but usually I operate on a Windows PC to connect to the server's console through SSH. Thanks to zsh and screen, I am able to enjoy the pseudo-terminal whenever or wherever necessary.
As for server software, Apache and PostgreSQL run for Web and database server, respectively. In addition, I have constructed and maintained several full-text search system where the search engine is Hyper Estraier or Senna with Ludia (PostgreSQL) or Tritonn (MySQL).
A programming language is indispensable for constructing some Web application in cooperation with the HTTP daemon and the database management system, so I like to write the programs with Ruby if it is maintained only by myself, while PHP or C is employed under collaboration with students.
I devote Windows PCs to my desktop computing life. My favorite text editor is Meadow, an Emacs-based software fitted into Windows. Instead of Command Prompt, I equip Cygwin to put shells (zsh or bash), GCC (GNU Compiler Collection), and Unix-like tools in use. Some documents are made with TeX (latex2e), and some with Microsoft Word. Other MS Office tools such as Excel and PowerPoint are also used regularly.
To share files through laboratory research, we introduced Subversion. Indeed it is intended mainly for version management, but Subversion allows us to exchange large files which we hesitate to send via e-mail.
