Added claen-up tag. At the very least needs extreme copy-editing; difficult to assess other issues because a) I am not an expert in this subject; b) The article is incomprehensible in its current form. May have been machine translated using e.g. Babelfish and cut 'n' pasted verbatim, and hence copyright issues could also be a problem (although may just have been ported over from the Japenese Wikipedia). Salvageable but needs work.
