The purpose of this study is to measure the acoustic properties of Tofu and Acorn Curd (Dotori Muk), which are possibly used as tissue mimicking materials (TMMs). Due to its availability and low cost, Tofu was suggested as a TMM by several researchers who measured only sound speed and attenuation. The acoustic properties of Tofu and Muk including the backscattering coefficient were measured in this paper. Sound speed was measured by the time shift in a pulse echo setup. Attenuation coefficients and backscattering coefficients were measured by a broadband method using both 5 MHz and 10 MHz transducers in the frequency domain. The measured acoustic properties of both Tofu and Muk are observed to be similar to those of biological tissues such as beef liver or beef heart.

Purpose The purpose of this study is to identify the influence relationship between BJ interactivity, explicitness of paid advertisements, flow, and product attitude in YouTube muk-bang, and to determine whether there are gender differences in the relationship between them. Design/methodology/approach In this study, an online survey was conducted targeting college students who watch YouTube muk-bang content using a questionnaire form provided by Google. 115 questionnaires were collected from April 1 to 15, 2024, and after excluding 15 insincere responses, a total of 100 questionnaires were used in the final analysis. Findings The results of the empirical analysis are as follows. First, the explicitness of including paid advertising was confirmed to have a significant impact on both flow and product attitude. Second, while BJ interactivity had a significant effect on flow, it was confirmed that it had no significant effect on product attitude. Third, flow was confirmed to have a significant impact on product attitude, and as a result of confirming the moderating effect due to differences between genders in the relationship between the variables set in this study, it was confirmed that there was no moderating effect.
