This study investigated the physicochemical and sensory characteristics of Jeungpyun prepared with various levels of barley flour and Hizikia fusiformis powder. The pH, volume, and spreadability of the dough as well as the moisture content, color, texture, and sensory evaluation of Jeungpyun were analyzed. The results show that the pH of dough decreased in all sample groups with fermentation time and ultimately revealed a pH level ranging from 5.36~5.44. The spreadability of the dough significantly decreased as the substitute amount of barley flour increased; the sample group with 1% Hizikia fusiformis powder showed a significantly larger spreadability than the sample group with 2% Hizikia fusiformis powder (p<0.01). The moisture content of Jeungpyun significantly increased as the substitute amount of barley flour increased (p<0.01). Lightness and yellowness were reduced as the substitute amount of Hizikia fusiformis powder increased. In measuring texture, the 50% sample group with a high substitute rate of barley flour was observed to have high characteristics of hardness, gumminess, and chewiness. The results of the acceptance test show that the sample group with substituted 50% barley flour and added 2% Hizikia fusiformis powder had a higher acceptance than the sample group with 0% barley flour in terms of color, flavor, texture, and overall acceptance.

The effects of water dropwort on the physical characteristics of tofu were investigated and consumer acceptance test was conducted. pH decreased significantly with increasing water dropwort concentration from 0 to 3%, whereas titratable acidity showed the reverse trend (p<0.05). The amount of water dropwort did not significantly influence the moisture content up to 2% substitution (p>0.05). Turbidity increased significantly with increasing water dropwort concentration (p<0.05). A significantly lower moisture content in 3% water dropwort tofu may be attributed to the denser structure and hardness of that was significantly higher than those of the other samples (p<0.05). Even though $a^*$-values of 3% water dropwort tofu was lower than that of control, $a^*$-values increased significantly with increasing water dropwort content (p<0.05). On the contrary, $b^*$-values decreased significantly with increasing water dropwort content (p<0.05). 2% water dropwort tofu was found to be the best with respect to its overall acceptability score.

Purpose: This study empirically examines the bandwagon effects on the adoption of Kiosks for the restaurants' owners. Utilizing Davis (1989)'s Technology Acceptance Model as a framework, this study contributes to the literature by adding a bandwagon effect variable. Bandwagon effect has been studied extensively on the consumer marketing domain in terms of end-user behavior, but not on the business owners' willingness to invest on the new technology. Research design, data, and methodology: Davis (1989)' Technology Acceptance Model with added a bandwagon effect variable was set as a theoretical model. Data was collected via survey instrument from restaurants' owners who purchased or are considering a Kiosk. Structural Equation Modeling was used to empirically test the proposed model. Results: Results show that bandwagon effect is indirectly affecting to the adoption of Kiosks via perceived usefulness, trustworthiness, and interests. The bandwagon effects are NOT directly affecting the adoption of Kiosks. Conclusion: The findings suggest that buyers of Kiosks as storeowners (not end users) consider buying them after storeowners check perceived interests and trustworthiness from others. Thus, there could be a practical implication that it is important to illustrate perceived interests for the business to the storeowners when marketing new technology.
