The objective of this study was to investigate the sensory quality characteristics of coffee under various processing and roasting conditions of green beans. Colombia green bean samples were obtained from three processing methods: natural, pulped-natural, and washed methods. The green beans were roasted differently according to Agtron number: light (Agrton #65), medium (Agtron #55), and dark (Agtron #45). Moisture content, density, color value, pH, and total dissolved solid contents (TDS) were measured, and quantitative descriptive analysis (QDA) with 23 sensory attributes was performed for nine coffee samples. Hunter L values were significantly elevated with the degree of processing but reduced with roasting intensity. The pH values of the nine coffee samples were 5.6~6.2 and significantly increased with intensity of roasting. TDS decreased with an increase in processing and increased with roasting intensity. QDA results show that smoky aroma and nutty and chocolate flavor significantly increased while fruit and floral aroma decreased with intensity of processing. The attributes of brownness, oily surface, smoky aroma, bitter and burnt flavor, and greasy and heavy mouthfeel significantly increased while fruity and floral aroma, black tea, sour and umami flavor, pureness, and softness decreased as roasting intensity increased. Principle component analysis showed the overall significant relationships between 23 sensory attributes and nine coffee samples under different processing and roasting conditions.

As interest in the high-potential Chinese beauty market is growing, understanding the disposition of Chinese consumers different from Korea is becoming more important for successful entry into the Chinese market. This study attempted to compare differences in beauty shop selection attributes between Korean and Chinese consumers. In order to achieve this research purpose, the beauty shop selection attribute was classified into five components: environmental attribute, structural attribute, external attribute, awareness, and service attribute. Survey responses were collected from 162 Chinese and 111 Koreans, respectively, and empirical analysis was conducted. Both Chinese and Koreans had significant relationships between environmental attribute, service attribute and satisfaction, but the relationship between the remaining attributes and satisfaction were not significant. In addition, significant differences exist between Chinese and Koreans in the relationship between environmental attribute, service attribute and satisfaction. The results of this study can help companies to establish and operate a higher quality beauty shop based on understanding the situation and characteristics of each country in the fierce competition in the beauty market.

The COVID-19 pandemic has significantly impacted the aviation industry, leading to worldwide changes in travel restrictions and security measures. This study analyzes 59,818 reviews of 147 airlines from the SKYTRAX website between 2016 and 2023 to understand the changes in airline service satisfaction before and after the pandemic. Using sentiment analysis, the study compares overall satisfaction, review sentiment, and attributes influencing satisfaction. The results show a statistically significant (p<0.001) decrease in overall satisfaction post-COVID-19, with reduced positive sentiment and increased negative sentiment for all airline selection attributes, except cabin and in-flight services. Flight operation services had the most significant impact on overall satisfaction during both periods. This quantitative analysis of global major airlines' satisfaction attributes before and after COVID-19 contributes to enhancing future service satisfaction in the airline industry.

In this paper we propose a new method of evaluating customers' service quality using triangle fuzzy numbers and semantic differential scale. These two parameters are useful for quantifying the customers' linguistic variables and subjective judgements. We define the Service Quality(SQ) as the ratio of the expected and perceived service and address the Agreement Rate(AR) calculated from the hamming distance in order to define the Service Rate(SR) as the geometric mean of the SQ and AR. Using the SR in the analysis of service attributes provides more appropriate to measure the customers' service quality and to establish a creative service policy for competitive service quality improvement.

This study explored the behavior and choice attributes of specialty coffee shop customers according to their general characteristics. The results showed significant differences by gender, age, occupation, education, and income. Female customers stayed longer, valued taste, and their importance perception toward employee and systematic service was higher compared to the males. According to age, younger customers (20's, 30's) stayed longer, visited coffee shops to meet friends and enjoy specialty coffee, and placed high importance on physical surroundings, systematic service, and taking out coffee. Whereas older (50's and 60's) customers valued the location and having coffee on-premise. In terms of education, ustomers with higher education visited coffee shops to enjoy their favorite specialty coffee. By income, those with higher ncomes valued the location and brand of the coffee shop, and their importance perception toward employee and ystematic service was lower than that of customers with lower incomes.

The purpose of this study is to establish the principles of an arrangement planning for children's playgrounds which can be contributed to offer the recreation opportuqities to all urban children equally. The study is specially focused on the service radius and the inducement rate in children's playground. The data in this study were made into field survey, dividing the park users into preschool children (below 6- year-old)and school children (7 to 12-year - old), through six sampling places in Taegu City. The results are summarized as follows : The using distance was becoming shorter according as the dencity of population was becoming high. There wart 75% of the users to service radius 250m prescribing in the present City Park Law. The service radius of preschool children was 260m and that of school children was 300m in average. To investigate the effects of several attributes on the inducement of children's playground, three of six children's playgrounds were selected based on three attributes of those which were width of area, percentage of green coverage and the pattern of facility arrangment. Of three children's playgrounds, Sankyok 3- dong which had the highest percentage of green coverage, the greatest width of area and the corner type in the arrangement was a slight tendency to become the same in the inducement rate of the two age group. In the using pattern of this Sankyok 3-dong. preschool children usually used a play facility, on the contrary, school children showed the active play pattern by using space.

This study is about online purchases of foods that have been reluctant to deal with distribution processes and reliability issues. We find out that attributes of the online food market affects behavior intention and whether it differs according to consumption tendency. A survey was conducted on consumers who had ever purchased food online for hypothesis testing. Reliability and feasibility were reviewed for the collected data and the hypothesis was verified through structural equation model analysis. While product diversity, product information and customer service factors of the online food market significantly affect behavior intention, price is not. We identified differences in the impact of behavior intention on consumption tendencies. For the Gaseongbi group, only the product information factors have significant effect on behavior, and for the Gasimbi group, the price and customer service factors have a significant effect on behavior intention. The findings provide theoretical and practical implications for marketers to study various marketing method based on consumer tendencies.

Purpose of the research: This study aims to explain the state of marketing using fun among recent popular marketing strategies. Although companies are using various differentiated marketing strategies to gain a competitive edge, among them, fun marketing has constituted the most effective area of interest recently. Research design and methodology: To extract the customer selection attributes of fun marketing, after reviewing the literature, six optional attributes were selected from the factors of fun marketing towards consumers such as funny design, language play, celebrity use, funny taste, how to eat, and newtro (new + retro). Out of 300 questionnaires, 276 were used for analysis, excluding unscrupulous or incomplete questionnaires. The results were reviewed for validity and reliability using SPSS andAMOS, and the hypothesis was verified using structural equation modelling (SEM). Principal results: The results showed that funny design, language play, and newtro statistically significantly affected customer satisfaction, but celebrity use, funny taste, and eating methods had no significant effect. It was also confirmed that satisfaction had a statistically significant effect on repurchase intention. Major conclusions: This study can serve as basic data to enhance the marketing strategy of the food service industry, and it provides theoretical and practical implications.

Various non-face-to-face services are being activated due to the influence of the Corona 19 virus around the world. However, unlike the rapid development of delivery services, social awareness of delivery services is causing many problems. Therefore, in this study, we analyze the quality attributes of delivery services from the consumer's point of view, and based on the results, we try to derive a direction for service improvement. In this study, quality factors were established through interviews and surveys with actual consumers, and quality attributes were classified through the Kano model and Timko's customer satisfaction coefficient. "Attractive" is ('Ease of ordering, Accurate delivery to the designated place'), "One Dimensional" is ('Variety of payment methods, Accurate delivery on time, Accurate delivery of ordered food, Degree of non-deformation of packaging conditions, etc., Convenience of use time'), "Must be" is ('Kindness of the delivery person'), "Reverse" is ('provision of services, service response to order discrepancies'). This study has academic significance in that it compensated for the disadvantage of not being able to interpret the mathematical meaning of the Kano model with Teamco's customer satisfaction coefficient. It also has practical implications in that it provides an indirect clue to future improvement directions.

A digital cable broadcasting service is a multimedia broadcasting service that provides high definition and various supplementary services by using digital transmission. Korea implemented a complete digital broadcasting service by 2012. This study applied a choice experiment to investigate consumer preferences, and it calculated the marginal willingness to pay for this service. Moreover, we employed a multinomial probit model to relax the assumption that all respondents have the same preference for attributes being valued. The results suggest that respondents value channels, definition, video-on-demand (VOD) service, pay-per-view (PPV) service, and commerce based on TV (T-commerce). On the other hand, online gaming may be less important as an attribute for digital cable broadcasting service in Korea.
