Abstract: These instructions give you guidelines for preparing papers for IJEMSR. Use this document as a template if you are using Microsoft Word. This word template is useful for estimating the length of an study but it is optional. The electronic file of your study will be formatted further at IJEMSR. Paper titles should be written in uppercase and lowercase letters. Avoid writing long formulas with subscripts in the title; short formulas that identify the elements are fine (e.g., “Nd-Fe-B”). Do not begin a title with the word “On.” Avoid starting a title with articles like “The” full names of researchers are much preferred but initials may be used instead. Chinese, Japanese and Korean researcher are encouraged to include their names in native characters in parentheses after their Romanized names. More information may be found at the journal website. Department names are optional in the affiliations. Do not give street addresses in the affiliations (except for researchers with no institutional affiliation). Define all symbols used in the abstract and again in the text. Do not cite references in the abstract. The purpose of this study is to analyze the knowledge and structure of creativity to understand the concept of creativity of preliminary designers and preliminary engineers among university students. In this study, 30 preliminary designers and 30 preliminary engineers among the university students of 2 universities located in Busan City were randomly sampled and 60 students were selected as research subjects. The findings of the study were as follows: First, both the preliminary designer and the preliminary engineer had the highest idea of ‘idea’ as the upper concept of creativity. Second, the number of the superordinate concepts that the prospective engineers described was 165 and that of the superordinate concepts used by the prospective designers was 136. As a result of categorizing the terms presented by the two groups based on similarity, their words were respectively classified into 19 categories. Third, as a result of analyzing their density scores on creativity, the density of the conceptual diagrams of the prospective engineers ranged from 1.00-2.62 and that of the conceptual diagrams of the prospective designers was between 1.00 and 3.42. The density scores of the two groups tended not to be high. The findings imply that their knowledge of creativity was parallel and not integrated properly rather than hierarchical and well organized.
