safety of medicinal use, therapeutic classification mark, transdermal Patch, clustering algorithm

Peoplefs consciousness of the safety of medical usage has not been investigated from the point of view of users of a medicine. Our research focused on the analysis of awareness of the safety to use transdermal patches, making use of the questionnaire whose respondents are doctors, pharmacists, nurses and patients who are the users of cardiac transdermal patches. Besides traditional statistical analyses, we applied a data-mining technique, agglomerated hierarchical clustering algorithm with our pseudo-distance measurement, to the questionnaire data. The results shows that medical experts support the validity of the transdermal patches and the design of the therapeutic classification mark. As a sub-product, they also revealed that the thought about the displays on labels differs depending on their occupations. Following the opinion of pharmacists and nurses, who deal directly with medicines, we concluded that we should promote the display of the therapeutic classification mark and product name.
