As for types of menus, the score of overall customer satisfaction was not significantly different between cafeteria menu and double choice menu.

An attempt was made to provide valuable information to improve service quality and customer satisfaction for in-flight catering service. The customers' demographic characteristics that impact on service quality and customer satisfaction were examined for a group of customer. 474 customers who have been used the airplane within 1 year were participated in this study. Statistical analysis was performed using SAS software program (version 6.01) for descriptive analysis, factor analysis, t-test and ANOVA. The results of the study can be summarized as follows: 1. Service Quality in In-flight catering was assessed on the basis of 18 service quality attributes and 5 dimensions derived from a factor analysis. After comparing customers' perception to customers' expectation regarding in-flight service quality, the quality of dimensions for 'meals', and 'sanitation' were not showed any significant differences. However, the expectation for dimensions of 'diversity of menu', 'providing information', and 'the degree of concern to the customers' were rated significantly higher than the perception for those. 2. Among the demographic variables, age and gender had highly influences on the customers' expectation and perception regarding service quality and customer satisfaction. 3. The korean food that the customers wanted to have for in-flight meals was investigated. Among the kinds of gruel(jook), abalone gruel(jeonbok-jook), pumpkin gruel(hobak-jook), and pine-nut gruel(jat-jook) were chosen to have for in-flight korean meals. It was rated that the preferences for beef soup(sogogikook), hot spicy beef soup(youkgaejang), brown sea-weed soup(miyoukkook) were higher than others in soup group. The preferences for boiled rice with assorted mixture(bibimbab) showed the highest and beef and rice soup(seoleongtang), boiled rice with four the staple cereals(ogogbab) were preferred higher than the others in main dish group. Bulgogi was rated the most popular dish. Korean style punch with omiza(whachae), sweet rice dish(yaksik) and fried glutinous rice cake(gangjeong)showed high preferences in dissert.

The aim of this study has been two fold - to analyze the degree of utilization of Korean menu items in family restaurants; and to evaluate consumer satisfaction with the quality of family restaurant food and food-related service. A self-completed questionnaire survey of 280 consumers having meals in 6 family restaurants in Korea was undertaken and detailed information was collected from each. Consumer satisfaction with the quality of food and food-related service in family restaurants was evaluated by consumer questionnaires. It was measured by assessing 24 variables. Statistical data analysis was using SAS package program for descriptive analysis, t-test and analysis of variance. Importance mean score of customers was 4.07 out of 5, with performance mean score of 3.19. The gap between importance and performance scores was 0.87. The Importance-Performance Analysis (IPA) technique was used for obtaining information of the degree of utilization of Korean menu items in family restaurants. By the results of the IPA technique, menu items with fair to poor performance and high importance to the customer were cooked meals, noodles, steamed and grilled dishes, Korean salads, kimchi, beverages, single-dish course, suggesting that customer seemed to be dissatisfied with the degree of utilization of Korean menu items in family restaurants.

Purpose - This study attempted to construct and validate a structural model of the relationship between the quality of medical services, perceived risk, reputation and customer satisfaction, which is the main concept of the relationship between large hospitals as well as small and medium hospitals and medical consumers. Through this verification, the small and medium hospitals are to find the way for wise coping in competitive situation with large hospitals. Research design, data, and methodology - This research developed a hypothesis by constructing a structural equation that reaches the satisfaction and the relationship between reputation of perceived risk and perceived risk of service quality perceptions of customers of small and medium hospitals. Research data were collected through a questionnaire survey of respondents who had medical service experience from small and medium hospital. A total data of 252 respondents were used as the sample for the final analysis and analyzed using SPSS 23.0 and AMOS 23. Results - As a result, the relationship of quality of medical service, reputation, and customer satisfaction among small and medium hospitals was consistent with the results of precedent studies, and the perceived risk has a significant impact on reputation, so the greater the perceived risk, the higher the preference for reputable medical institutions as large hospitals. In addition, it was found that the direct route from perceived risk to customer satisfaction was not significant, and reputation was found to have a full mediating effect on perceived risk and customer satisfaction. Customers who use small and medium hospitals prefer to use reputable medical institutions if their perceived risk is high, which is different from risk perception when specific targets are specified. Conclusions - In terms of the effect from customer satisfaction, not only the path of perceived risk → reputation → customer satisfaction, but also the quality of service quality → reputation → customer satisfaction. These findings suggest that small and medium hospitals are appropriately responding to competition with large hospitals, rather than focusing on the perceived risks and reputation of customers in establishing and utilizing competitive strategies to create new customers and preserve existing customers

Purpose - The purpose of this study is to classify the quality factors of chicken restaurant customers with the service quality based on the SERVQUAL, the quality factors based on the selection attributes and service qualities of chicken restaurants used in the previous studies.

Thirdly, it showed that service encounter quality, purchase quality, and cleanliness had a positive impact on trust, respectively. Fourthly, it showed that customer satisfaction had a positive impact on behavioral intention. Additionally, it suggested that customer satisfaction of chicken restaurant consumers had a positive impact on behavioral intention and thereby, higher customer satisfaction leads to higher levels of reuse and recommendation intention. Lastly, after checking the effect relations of trust between customer satisfaction about chicken restaurant and behavioral intention, it was analyzed that customer satisfaction has a positive impact on trust and trust has a positive impact on behavioral intention. On the other hand, it showed that trust have a partially mediating effect in the relations between customer satisfaction and behavioral intention. But, it showed that product quality, aesthetics, overall interior, purchase quality, and convenience did not have a positive impact on customer satisfaction. Conclusions - Chicken restaurant consumers put more priority on friendly and good services of chicken restaurant staff in service encounter and delivery order, rather than on reasonable price and discount systems. Thereby, chicken restaurant marketers need to take factors like service encounter quality, cleanliness into more consideration.

한때 K 뷰티 열풍과 함께 호황을 이루던 로드숍이 위기를 맞게 되었다. 로드숍 경영 악화의 여러 이유 중 드러그 스토어의 성장과 함께 변해가는 소비자의 성향과 트렌드를 이해하지 못하는 것이 가장 큰 원인으로 보고 있다. 현재 소비시장의 핵심 고객 세대는 베이비붐세대에서 밀레니얼 세대로 변하였고 핵심 고객의 특성을 조사하는 과정에서 밀레니얼 세대는 경험을 중요시한다는 것을 알 수 있었다. 본 연구는 뷰티숍 경험을 바탕으로 서비스 디자인을 제안하였다. 먼저 현 뷰티 시장에서 세 가지 브랜드로 좁혀 사례마다 데스크 리서치 하였다. 각각의 브랜드는 체험적 요소를 다양하게 적용하고 제품과 함께 다양한 이벤트를 제공함으로써 경험적 서비스 제공하고 있었다. 이후 미스터리쇼핑을 통해 각 매장의 체험 요소와 뷰티 브랜드 서비스를 경험하여 여정 맵을 그리고 소비자의 고객 경험 포인트가 매장, 제품, 서비스로 범위가 나뉘면서 경험 포인트별로 로드숍의 이용자를 대상으로 인터뷰 내용을 작성하였다. 인터뷰의 답변을 모아 두 명의 퍼소나를 설정하였고 제품 구매를 목적으로 하는 상황과 일상에서 코스메틱 제품이 필요한 상황으로 나누어 고객 여정 맵을 그렸다. 그 결과 매장 안의 제품에 대해서 5가지, 매장 환경에 대해서 3가지, 매장에서 경험하는 서비스에 대해서 5가지의 페인 포인트(Pain point)를 발견하였다. 발견한 페인 포인트(Pain point) 중 제품 정보 습득에 대한 불편함, 포인트에 대한 적은 기대치, 브랜드 서비스의 해결방안에 중점을 두어 애플리케이션을 활용한 서비스 디자인을 제안하였다. 본 연구에서 제안된 코스메틱을 위한 애플리케이션 서비스는 고객뿐만 아니라 뷰티 전문가, 코스메틱 업체 모두 만족할 수 있는 서비스 디자인으로 소비자와 소통하고 경험 디자인을 통하여 브랜드 가치 상승과 충성고객을 이끌어 가는 매개체가 되길 희망한다.

Purpose - With the economic development in China, the lifestyle of Chinese customers has changed dramatically. Chinese customers are more likely to have coffee in a shop with the ability to make them happy than those with high quality coffee in a nice physical environment. Happiness becomes a critical driver of customers’ intention to purchase a cup of coffee in a specific coffee shop again and again. As a result, happiness becomes an important factor for managers to make strategies for attracting customers. Although managers and scholars pay more attention to emphasize the importance of happiness in customers’ consumption, little research has been conducted to investigate the relationship between happiness and coffee shop’s continuous usage intention in the Chinese coffee industry. Research design, data, and methodology – A research model is made to explain the impact of happiness on customer’s behavior. To understand the influence of happiness better, we consider two dimensions of happiness which are subjective well-being and psychological well-being. In order to confirm the relationships of the variables in the research model, the online survey is constructed in China. Customers who have experienced the services in a coffee shop are asked to do the questionnaire. With 453 reliable questionnaires, structural equation modeling is used to analyze the causal relationships of the coffee quality, physical environment, subjective well-being, psychological well-being, and continuous usage intention. Results - Results indicate that coffee quality and physical environment are not the direct factors that influence customers’ continuous usage intention. However, good coffee quality and physical environment are the significant predictors of Chinese customers’ happiness associated with subjective well-being and psychological well-being, which in turn affects customers’ continuous usage intention. Conclusions - In this study, it is proposed that coffee quality and physical environment may be the key factors influencing customers’ happiness. Happiness, including subjective well-being and psychological well-being matters in decision making process. More importantly, happiness increases the continuous usage intention when the coffee shop can serve customers with higher quality coffee at a good atmospheric place. Managers should consider happiness as an important factor in making marketing strategies to compete in this industry.

Purpose - Customer loyalty and citizenship behavior are key success factors of franchise system. They make the management of franchisee more effective and efficient. Prior studies, however, mainly dealt with only acquisition utility of customer, such as perceived product/service quality and brand reputation to explain customer loyalty and citizenship behavior, which explains only on one side. We tried to investigate the effect of exchange utility of customer, such as relationship strength and psychological obligation together with the acquisition utility. In addition, we tried to investigate the relationship between customer loyalty and citizenship behavior in franchise context. Research design, data, and methodology - This study used data collected from the dining franchisee managers of 342 franchisors in South Korea. The franchisors consist of more than ten franchisees, the majority of which participated directly in the transaction with franchisor and have worked for more than six months. To test the hypotheses, the study used structural equation model analysis. Results - H1-1, 1-2, 1-3 predicted that acquisition utility would increase customer loyalty to franchisee. In support of H1-1, 1-2, 1-3, the results indicated that acquisition utilities such as perceived product value, perceived service value, and franchise brand reputation had positive effects on customer loyalty. H2-1, 2-2 predicted that exchange utility would increase customer loyalty to franchisee. In support of H2-2, the result indicated that psychological obligation had positive effects on customer loyalty like other acquisition utilities. However, H2-1 was not supported. Relationship strength had no significant effect on customer loyalty. H3 predicted that customer loyalty would increase customer citizenship behavior. In support of H3, the results indicated that customer loyalty had positive effect on customer citizenship behavior. Overall, the evidences generally supported the hypotheses. Conclusion - The results of the study show that not only acquisition utility but also exchange utility increases customer loyalty to franchisee and also show that customer loyalty increases customer citizenship behavior. Interestingly, however, relationship strength has no significant effect on customer loyalty. These results have two implications. The one is that increasing exchange utility can improve customer loyalty as acquisition utility can. The other one is that both of customer utilities can improve customer citizenship via customer loyalty.

Purpose - To meet the needs of various customers in an uncertain market environment, many companies use product modularization strategies. Modularization of a product means that one product consists of several components and that the type of product can be changed according to the combination of components. The greatest feature of modularity is that changes in one component do not significantly affect the physical changes in the other component to which they are connected. Modularization of products is recognized as a very important strategy to reflect increasingly complicated customer requirements to products and respond to the needs of various markets. Many studies have been made in connection with the concept of mass customer satisfaction. There are many prior studies that modularization of such products positively affects the operational performance (manufacturing cost, fast delivery, etc.) and innovation of the product. However, excessive modularization has been found to have a negative effect on this performance. However, there are very few studies on the nonlinear relationship between product modularization and customer satisfaction. Supplementing these academically insufficient parts is very necessary when considering the current market environment. Research design, data, and methodology - In order to make up for the shortcomings of academic research in Korea, this study collects data through questionnaires in electronic, auto, and defense industry. This is because these industries are using modularity of products. based on lots of previous studies and information overload theory, we made two hypothesis and verify with empirical analysis. All 108 data were used. We used the R program and SPSS program for statistical verification. Results - As a result of the study, modularization of products showed positive relationship with customer satisfaction to a certain level. However, it has been found that when the modularization is over and beyond a certain level, there is a negative relationship with customer satisfaction. Conclusions – Excessive modularization of products can have a negative impact on customer satisfaction. This result can be understood as a result of human limited rationality due to information overload. Therefore, it is important for companies to apply appropriate modularity to product design.
