Countless symbol-marks that are produced and utilized in Korea currently have somehow lost their nationality and significance. In addition, the serious problem of imitation is being raised. As a result of deducing the original form of Korean-style symbol-marks in this age of information, it was prescribed that the sun symbol-marks that have come about through the harmony between consciousness, for beauty and sun worship which are in fact the spiritual principles governing the creative activities of the Koreans at root, are the Korean-style symbol-marks. They were categorized into seven groups of concepts. Their ideographic representation and significance were observed and later the theoretical background of the Korean-style symbol marks were organized. Furthermore, through a table which have arranged the marks in chronological order, this study presented future tendencies for the style of expression to return its primitive original form.
