This study divided the structure of the introduction into the periphery and the center of the university student report to examine how the composition of the introduction was structured and what type of vocabulary(phrase) was used. So far, we have summarized the following. First, the introduction of general facts was the highest at 31.7%, followed by 27.7%. Second, as for the central component of the introduction of the university student report, 97.5% of the research purpose was found to be important in identifying the purpose of the research in relation to the function of the introduction. Third, as a result of examining the use of vocabulary(phrase) for each component, the usage type of the vocabulary(phrase) of peripheral components appeared more diverse than the center. This is related to the fact that peripheral components have more diversified central components. Therefore, based on the analysis of the actual situation so far, the basic requirements of all the reports given in relation to the liberal arts and major classes of the university must be included in the central component of the introduction. Training on discourse markers used in the component will be required.
