  1. Multilanguage -Internationalization -The language is not enough Michio Kimura M.D. Ph.D. Director and Professor of Medical Informatics Department Hamamatsu University School of Medicine JIRA DICOM Committee Advisory

  2. Three types of representation-- We have 2 patient names in HIS • Alphabetic • Ideographic • Phonetic • Ideographic names • have many ways to pronounce • are difficult to sort Michio Kimura M.D. Ph.D. Hamamatsu University School of Medicine

  3. Multi-Byte Character Codesin Use in Asia • Korea: KS X 1001, and 1001 annex 3 • Hanguls(phonetic) and Ideographics • China(PR): GB 18030-2000 • Taiwan(ROC): CNS 11643, and Big-5 • Japan: JIS X 0208-1997 • Katakana, Hiragana(Ph.) and Ideographics • Junior school pupils must read/write 810 letters. • Varieties: 6879(JIS) to 48711(CNS) Michio Kimura M.D. Ph.D. Hamamatsu University School of Medicine

  4. Byte-wise Representation of ISO2022 Michio Kimura M.D. Ph.D. Hamamatsu University School of Medicine

  5. RFC 1468: Japanese Character Encoding for Internet Messages • ISO-2022-JP • Within 7-bit, safe for most nodes • Every line starts/ends with ASCII • No carryover shifting • ISO-2022-KR is also used in Korea • Same method is in DICOM(Supplement 9), and HL7 v.2.3.1 Michio Kimura M.D. Ph.D. Hamamatsu University School of Medicine

  6. UNICODE: ISO10646 • “Allocating 2 bytes for every character, UNICODE can represent every character in the world without any status nor shifting technique.” • 16 bits=65,536 • -> CJK unified ideographics Michio Kimura M.D. Ph.D. Hamamatsu University School of Medicine

  7. CJK Unified Ideographics Michio Kimura M.D. Ph.D. Hamamatsu University School of Medicine

  8. Why we do not use UNICODE as Message? (I know it is used inside, but, we do not like it go outside as message format.) • If Chinese “Bone” and our “Bone” are to be recognized same, because of symmetry, how about using these? • UNICODE consortium says “Introduction of Language information”. • We cannot write “Chinese language textbook written in Japanese. • We cannot accommodate Koreans living in Japan with their name properly in Korean letter, but their address is Japanese, of course. • Original UNICODE dream is gone. Michio Kimura M.D. Ph.D. Hamamatsu University School of Medicine

  9. HL7 Japan’s answer to HL7 v.3 • In XML, UNICODE will be default in 2003. • Even in UNICODE v3.1, “over-unification” problem is not solved. • But with XML schema and XML namespace, font information can be set in each tag. • By this, Korean name in Japanese address can be described. • Original UNICODE dream (all languages in the same time) is gone, but “many 1 byte languages + one 2 byte language” is not bad. • Pokémon • Answer: “UNICODE can be default, provided that we can continue to use each local practice now being used.” Michio Kimura M.D. Ph.D. Hamamatsu University School of Medicine

  10. Language representation is not the only issue • Language used in; • Conversation with patients • School education • Medical, Nurse, Technicians • Medical record • Signs and symptoms • Reports • Structure of data types • Address • 250 Wu-Hsing street • 1-20-1 Handa cho Michio Kimura M.D. Ph.D. Hamamatsu University School of Medicine
