        This study was conducted to examine the effects of Chinese perceptions of quality attributes on customer’s satisfaction, revisit intention and recommendation intention for coffee shops in Beijing, China. Subjects of this study included 200 customers who had visited a coffee shop at least once during the last year. Statistical analyses were performed using SPSS v23.0 and AMOS v21.0. In this study, the majority of customers visited a coffee shop once or twice a week with friends. Respondents preferred tall-sized warm coffee in the store. The coffee shop quality attributes of were derived from five exploratory factors identified upon analysis of 30 observational variables. It was important to maintain and strengthen the quality attributes of coffee shops in this area because IPA(Importance Performance Analysis) analysis showed that “Doing great, keep it well” part was a desirable area because it had high importance and performance. Finally, path analysis revealed that customer satisfaction was influenced by employee attitude and affected revisit intention and recommendation intention.

        The two-way quality theory has been widely used as a method for classifying quality attributes for several decades. In particular, the Kano model that classifies attributes into not just conventional one-dimensional but must-be and attractive has gained popularity due to its applicability and ease of use. However, the wordings of the five alternatives in the Kano's questionnaire has been criticised for unclear meanings. This study proposes a new two-way model to classify attributes using 5-point Likert scale alternatives. For this, the current paper investigated a case of TV sets to examine how the proposed model works in comparison with the Kano model. The application results of the proposed model are different from the original one. The two-way model classifies quality attributes in more detail such as the “one-dimensional with an attractive tendency” attribute, which has a greater influence on satisfaction than dissatisfaction, the opposite “one-dimensional with a must-be tendency” attribute, and “highly one-dimensional” and “less one-dimensional” attributes. In this study, a potential satisfaction coefficient (PSC), a potential dissatisfaction coefficient (PDC), and an average potential coefficient (APC) to manage quality attributes are proposed and discussed for their utilization.

        Effects of superheated steam (SHS) temperature (120, 150, 180, 220°C) and time (2, 5, 8, 10 min) on product quality attributes of snack-type ginseng chips were studied. Ginseng chips dried at faster rate under a higher SHS temperature. Higher SHS temperature resulted in ginseng chips with lower moisture content and water activity. After SHS treatment, lightness (L values) and redness (a values) of ginseng chips decreased significantly whereas yellowness (b values) of those increased. Although crude saponin content in ginseng chips reduced slightly after SHS treatment, chips treated at 150°C for 5 min had the highest saponin retention among samples. Scanning electron microscope analysis revealed that SHS treatment cause the shrinkage at the surface first, forming compressed cell layers. As treatment proceeded, pores and cavities were formed internally, resulting porous structure. These results suggested that SHS treatment shows great promise in production of snack-type ginseng chips by reducing drying time without any quality deterioratio

        We developed a type of sausage made of chicken breast and liquid egg whites for consumers interested in weight management. To determine the quality of the product, its chemical characteristics, fatty acid composition, free amino acid contents, and nucleotides contents were evaluated during 4 weeks of storage. Sensory evaluation was conducted by both general consumers and body-builders. The sausage was proposed as a fat-free product as fat content was 0.12% based on the Korean Indication Standard of Animal Origin Food. Protein content was 13.42% and calorie value was 61.50 kcal/100 g of the sausage. In sensory evaluation, the mixture of chicken breast and egg whites stuffed into the same casing had an adverse effect on taste, color, texture and overall acceptance while the product that contained egg white stuffed separately into the outer casing enclosing the chicken breast (double layer) improved these attributes. The developed double-layer sausage can last for at least 4 weeks of storage without quality deterioration of flavor-related compounds, such as fatty acids and nucleotides.

        Create, develop, maintain and nurturing the passengers-airline relationships is crucial in a very competitive market in Europe. Relationship quality and behavioural intentions to fly again in the same airline carrier and recommend to others are core outcomes which may result from a favourable travel experience over time. However, the complexity and the multidimensional phenomenon lead us to develop a holistic framework, which posits that relationship quality and behavioural intentions do not depend on individual air-flight attributes and other individual demographicpsychological variables but on specific configurations of such attributes and variables. Thus, the framework of this study is investigated using qualitative comparative analysis and a sample of 304 passengers. Accordingly, the property space consists of all combinations of binary states, that is, presence or absence, of the 7 in-flight attributes (air quality, temperature, odour, noise, crew, layout and equipment/amenities), frequency of fly in an airline carrier, the type of airline carrier and demographic-psychological variables (age, gender, mindful) (that is, 212 combinations or configurations). Data from both Portuguese and non-Portuguese passengers, who have air travel experiences through Europe in both low cost carriers and legacy airlines (also called traditional or flag airlines) are used to test the hypotheses. The Lisbon airport agreed in helping to conduct the survey during October 2015. Research Question: Which configurations of in-flight attributes, demographicpsychological variables, frequency of fly in an airline carrier and type of airline carrier lead to relationship quality and behavioural intentions? The findings of the current study highlight the importance of coaligning the multiple attributes of air-flight attributes and other individual demographic-psychological variables, also including the frequency of fly in an airline carrier and type of airline carrier, for increasing relationship quality and behavioural intentions. Here the findings point out that complexity theory and QCA are useful tools for understand that simple antecedent conditions relate to an outcome condition of interest positively, negatively, and not at all, which of these three relationships occur depends on the observed complex antecedent conditions in which the simple antecedent conditions occur. Positive outcome (relationship quality or behavioural intention) is not the mirror opposite of negative outcome. By employing QCA, airline managers in Europe can identify whether and under what circumstances individual attributes and other variables will increase (or decrease) the relationship quality and behavioural intentions. QCA can also help managers uncover alternative ways for combining the attributes in order to induce behavioural intentions. Overall it is possible to see that crew and equipment & amenities, particularly for mindful passengers, emerge in several configurations as essential elements for the four outcomes: satisfaction, trust, affective commitment and behavioural intentions. For passengers not affectively committed to an airline, satisfaction plays an important role in their behavioural intention to fly again in the same airline carrier and recommend it to others. The combination of trust and affective commitment may also generate the intention to fly again in the same airline carrier and recommend it to others, particularly for mindful passengers. The findings contribute to managerial practices by providing new insights for improving the in-flight service provide and process. The findings also contribute to theoretical advancing of how passengers’ in-flight evaluations and their experience with an airline relate to their assessments of relationship quality and behavioural intentions.

        The noodle market has been worldwide expanding by the rising tide of the convenience food trend and various consumer acceptances. With this trend, a great deal of effort had been made to enhance the quality attributes of instant noodles to satisfy the demand of current consumers. In this presentation, two primary topics related to the quality attributes of noodles are discussed – production of non‐wheat noodles slit from sheeted dough and reduction of noodle cooking times. First, corn proteins were utilized to form a viscoelastic protein network of non‐wheat dough and their rheological and structural properties were characterized to prepare the noodles slit from sheeted dough. The extended β‐sheet alignment imparted high mixing stability to the non‐wheat dough that could be successfully sheeted and slit to noodle strands without gluten. Second, a novel thermal technology based on the modified transient plane source method was applied in order to characterize the cooking property of instant noodles. The porous structure of wheat‐based noodles was also built up to shorten their cooking times. After cooked, the porous‐structured noodles exhibited higher thermal conductivity and lower firmness, possibly indicating the shortened cooking time. 19

        Noodles have been a part of our diet for a long time. In Asia, white-salted, Cantonese and instant fried types of noodles are widely consumed. White-salted noodles, also called Udon noodles, are consumed as wet or dried form. White-salted noodles are deeply favored in Korea and Japan and more consumption of Cantonese noodles are observed in other Asian countries. The quality attributes of white-salted noodles are predominantly dependant by wheat flour components, such as starch, protein and pigments, as wheat flour, water and salt are main raw materials of white-salted noodles. In several studies, the ratio between amylose and amylopectin is a key determinant of textural properties of white-salted noodles; hardness of white-salted noodles did have a significant (p<0.05) increase when amylose content in wheat flour was increased. The textural properties of white-salted noodles was not affected much by the protein content, especially protein content of flour was in the range of 10% ~ 13%. It seems that starch plays more important role than protein in the textural properties of white-salted noodles. Carotenoids and flavonoids pigment are major contributors of color of white-salted noodles.

        Determining relative importance among many quality attributes under financial constraints is an important task. The weighted value of an attribute particularly in QFD, will influence on engineering characteristics and this will eventually influence the whole manufacturing process such as parts deployment, process planning, and production planning. Several scholars have suggested weighting formulas using CSC (Customer Satisfaction Coefficient) in the Kano model. However, previous research shows that the validity of the CSC approaches has not been proved systematically. The aim of the present study is to address drawbacks of CSC and to develop APC (Average Potential Coefficient), a new approach for weighting of quality attributes. For this, the current study investigated 33 quality attributes of e-learning and conducted a survey of 375 university students for the results of APC, the Kano model, and the direct importance of the quality attributes. The results show that the proposed APC is better than other approaches based on the correlation analysis with the results of direct importance. An analysis of e-leaning’s quality perceptions using the Kano model and suggestions for improving e-learning’s service quality are also included in this study.

        I suggest a new method to determine the importance values of quality attributes which use the satisfaction index and dissatisfaction index of customer in Kano's model. A case study of TV set are solved by the proposed method and the result is compared with AHP pairwise comparisons and ASC(Average Satisfaction Coefficient). The results of the proposed method is similar with those of AHP pairwise comparisons and ASC. The proposed method is an effective tool to determine the importance values of quality attributes to supplement existing research's shortcomings.

        The purpose of this study is to explore the applicability of QFD to product development of clothes by empirically applying it to development of a specific clothes, middle and elderly women’s formal knitwear. The voices of customers(VOCs) for formal knitwear was collected through in-depth interviews with 25 customers, shop masters, and designers. Also, questionnaires of which respondents were 230 customers were used to rank the importance of the items of VOC. A QFD team of 10 knitwear experts implemented the task of translating VOCs into design attributes and measuring the values of the relationships between VOCs and design attributes. Importance ranking of the items of design attributes was obtained based on Lyman’s method. The results of this study were as follows. First, the customer requirements for formal knitwear were classified into five dimensions, that is, symbolism, aesthetic, fitness, usefulness, and maintenance. Second, the descending order of the necessity of improving the quality was maintenance, aesthetic, fitness, usefulness, and symbolism. Third, three-staged design attributes were obtained as a result of translating of VOCs into design attributes. Lastly, the descending order of the importance of design attributes was “sorts of yarn”, “sorts of color jacquard”, “color”, “tone”, “ease”, etc.

        The purposes of this study were to analyze importance and performance for coffee quality attributes based on customers according to their consumption types; and provided ideas and marketing strategies to increase sales through IPAs (Importance-Performance Analysis). University students in Incheon were conducted a survey from March 13, 2007 to March 31, 2007. As for a quality attribute with the highest importance, the survey showed 'price' was important for 「vending machine coffee」, and 'taste' was important for 「commercial coffee」, and 「coffee house coffee」. And 'thirst relief' was found to have the lowest importance for three types of coffee. As for a quality attributes with the highest performance, the survey showed 'taste' was important for 「coffee house coffee」 'price' was important for 「vending machine coffee」; and 'period of circulation' was important for 「commercial coffee」. IPA results for coffee quality attributes also showed quality attributes that should be improved quickly for each type of coffee: 'hygiene', 'safety', 'period of circulation', and 'package' were for 「vending machine coffee」; 'price' and 'freshness' were for 「commercial coffee」; and 'price' and 'period of circulation' were for 「coffee house coffee」.
