Abstract
Professor Emeritus Fujio Mizuoka of Hitostubashi University, read a paper at the Third Global Conference on Economic Geography 2011 in Seoul, Korea. Judging from the abstract available via the internet, it includes some misunderstanding on rules and customs in Wikipedia. In addition, it also includes some passages which closely resemble comments made by a user of Japanese Wikipedia, Keizai-Chi-Tanuki-Gakkai or, a "raccoon dog". The user made comments in Japanese, which are almost identical with phrases found in Professor Mizuoka’s abstract in English. As of July 2015, the user has made no response to my questions to him/her raised in Wikipedia in 2010. If this user actually is Professor Mizuoka himself, he should explain why he declined to continue discussion or conversation within Wikipedia. Meanwhile, if the Professor is not the "raccoon dog", he should justify his possible violation of other person's copyright.
