ABSTRACT
Although terminology requires continuous consideration of recorded technical terms, extracting these terms manually is difficult, because the number of recorded terms is constantly increasing. Text-mining acquires information from numerous documents, and is capable of extracting technical terms. The purpose of this study is to extract candidate terms using text-mining toward updating the terminology of Japanese society of radiological technology (JSRT). First, the subjects for this study were textbooks published by the JSRT, and morphological analysis was conducted, which is an analysis to break the books up into meaningful words. Additionally, index terms of textbooks were extracted. Second, we observed overlaps between the JSRT technical terms and the terms obtained from the morphological analysis and the indexes of textbooks and the extracted terms were absent in the JSRT terminology. The overlap was 53.6% (3090/5770 terms). The terms, "imaging technology for magnetic resonance" and "information and system in radiological technology" were missing from the JSRT terminology. From these results, it was estimated that half number of the JSRT technical terms were changing with time. This study demonstrated that text mining showed the differences between old and new technical terms.

This study attempted to clarify whether medical radiological technologists of the Japanese Society of Radiological Technology in Gunma sought to obtain Bachelor degrees and Master of Science degrees. In September 2005, a postal questionnaire survey was conducted on a sample of 153 technologists, and 68.0% (104/153) of the questionnaires were returned. The percentage of respondents who wished to obtain a degree was 25.0% (26/104) . The first reason for wishing to obtain a degree was to improve the quality of their work 47.8% (11/23) . Moreover, 28.8% (30/104) of respondents indicated a desire to obtain a master's degree. A total of 103 respondents indicated the subject they wished to study: 45.6% (47/103) indicated their own specific area, and 34.0% (35/103) indicated clinical psychology. The results of the survey showed that a high ratio of radiological technologists in Gunma would like to obtain an advanced degree. Even the radiological technologists who did not wish to obtain an advanced degree indicated their desire to continue in more specialized areas of radiology. The above investigation suggested some ways to implement lifelong education at the Gunma Prefectural College of Health Sciences.
