  • Changes in social, economical, and cultural environment affect the manner in which mourners greet those expressing condolence to the deceased. While the funeral process was done at home in the past, nowadays, most families prefer a funeral home. Funeral homes provide all necessary services for the funeral process, including food for visitors and rituals. This research was conducted using a questionnaire in the Kyonggido area. Overall food satisfaction level of visitors was moderate; satisfaction with cleanness was the highest, followed by taste, quality, freshness, and diversity. Satisfaction level of foodservice by the type of funeral homes showed home funeral was highest, followed by general funeral home, hospital funeral home. Regarding the acceptance of food items served at the funeral home, Yukgaejang was the most preferred, followed by Gaorichomuchim, Pyeonyuk, Kodarichim, and Injeolmi. There were differences in food acceptance according to age and gender of visitors. Male prefers Samgyeopsal-suyuk to Pyeonyuk. but female prefer Pyeonyuk to Samgyeopsal-suyuk. Elder individuals preferred Kodarichim, Gaoricho-muchim. Younger individuals preferred Jeon, Ojingeodorajimuchim, and Samgyeopsal-suyuk.

  • Color is one of the most important attributes determining the purchase of food products by consumers. Therefore, the purpose of this study was to identify consumer color preferences for songpyun, a traditional Korean rice cake, by a consumer acceptance test and using coated Pantone color chips. Color evaluation tools for the study were developed accordingly. From the results, the songpyun sample designated as product E was given the highest color acceptability score, and was 'slightly liked' (p<0.05). The color of product E was 'very pale red-purple'. All the evaluated pink-color songpyun products were based on this red-purple hue, however, they had differences in tone. The consumer panel favored a pale tone over a bright tone. The color concept for traditional songpyun within the pink color category was identified as 'very pale red-purple', using coated Pantone color chips. This result for the conceptual color preference was consistent with that of the consumer color acceptance test. Thus, color chips could be an effective tool when applied for color standardization in traditional foods production. From the overall results, it seems consumers are perceiving color trends and are willing to adapt to such changes in food applications.

  • 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.

  • The study investigates the various Acceptance Control Charts (ACCs) based on the factors that include process independence, data weighting scheme, subgrouping, and use of control charts. USL - LSL > $6{\sigma}$ that used in the good condition processes in the ACCs are designed by considering user's perspective, producer's perspective and both perspectives. ACCs developed from the research is efficiently applied by using the simple control limit unified with APL (Acceptable Process Level), RLP (Rejectable Process Level), Type I Error $\alpha$, and Type II Error $\beta$. Sampling interval of subgroup examines i.i.d. (Identically and Independent Distributed) or auto-correlated processes. Three types of weight schemes according to the reliability of data include Shewhart, Moving Average(MA) and Exponentially Weighted Moving Average (EWMA) which are considered when designing ACCs. Two types of control charts by the purpose of improvement are also presented. Overall, $\alpha$, $\beta$ and APL for nonconforming proportion and RPL of claim proportion can be designed by practioners who emphasize productivity and claim defense cost.

  • Drawing on the literature on TAM and presence, this study proposes a model of the extended TAM by identifying factors that affect the motivations to enhance our understanding of online consumers' acceptance of an e-tail website. This study conceptualizes that consumers' perceived presence variables such as telepresence and social presence are the antecedents to the motivations of TAM. Empirical tests using regression analyses generally supported the proposed model. The overall conclusion from the current data is that our integrated model is useful in understanding consumers' acceptance of an apparel e-tail website. The findings show that perceived usefulness, perceived ease of use, and perceived interest motivations act as strong determinants of consumers' attitude toward an e-tailer, which leads to their behavioral intentions about the e-tailer. This suggests that apparel e-tailers should consider these three motivations when they design their websites. As one way to influence these three factors, this study showed the role of perceived presence in the usage of an apparel e-tail website. The findings suggest that online consumers' perceptions of "being there" and "socialness" stimulate their perceptions of usefulness and interest in the website use. Thus, e-tailers should consider effective ways to increase consumers' perceived presence.
