The purpose of this study is investigating how sport-utilized 5G advertisement attribute affects advertising attribute and advertisement acceptance intention to provide empirical basic data for effectively utilizing sports advertisement contents. For the subject of the study, customers from more than 20 years of age who experienced the sports-utilized 5G advertisement were selected as the population, and online questionnaires were distributed; total 286 cases were used for final analysis. The questionnaire is consisted of total 27 questions using 5-point Likert scale. For data processing, statistical analysis software SPSS 22.0 were used for the frequency analysis, the exploratory factor analysis, the reliability analysis, the correlation analysis, and the multiple regression analysis. The results are as following. First, advertisement a ttitude had meaningful effect on advertising attitude. Second, advertisement attribute had partially meaningful effect on acceptance intention. Third, advertising attitude had meaningful effect on acceptance intention. Putting together the above results, it can be decided that the sports-utilized advertisement sets up favorable and positive feelings to new technology consumers and that the sports field has very large possibilities as a marketing factor to approach various fields like cutting-edge technology. Therefore, when a new technology emerges in various industries, not only applying sports as a product of the advertisement, the advertisers or the large advertising agencies can utilize sports contents to facilitate communication with the public and a positive effect is expected from it, based on this study.

LED scraps consisting of highly crystalline GaN and their leaching behavior are comprehensively investigated for hydro-metallurgicalrecovery of rare metals. Highly stable GaN renders the leaching of the LED scraps extremely difficult in ordinaryacidic and basic media. More favorable state can be obtained by way of high temperature solid-gas reaction of GaN-Na2CO3powder mixture, ball-milled thoroughly at room temperature and subsequently oxidized under ambient air environment at1000-1200 ℃ in a horizontal tube furnace, where GaN was effectively oxidized into gallium oxides. Stoichiometry analysisreveals that GaN is completely transformed into gallium oxides with Ga contents of ~73 wt%. Accordingly, the oxidized powdercan be suitably leached to ~96% efficiency in a boiling 4 M HCl solution, experimentally confirming the feasibility ofGa recycling system development.
