The purpose of this study was to develop service quality dimensions for fashion retail stores and to identify significant service quality dimensions influencing customers satisfaction for each fashion retail store. 687 young adults completed written questionnaires consisting of items related to service quality. For analysis of data, confirmatory factor analysis, one-way ANOVA, scheffe test, and stepwise regression analysis were applied. The results were as follows: 1. The service quality dimensions of fashion retail stores were tangibles, reliability, responsiveness, assurance, empathy, fashionability and variety, price, convenience, merchandise quality and credit card usability. Among those 10 main dimensions of service quality were grouped as experience attributes and search attributes. 2. In examination of the highest valuable service quality dimension based on the types of stores, imported fashion stores were evaluated the highest in terms of all factors except price, tangibles and credit card usability. 3. To predict consumer satisfaction, service quality dimensions such as reliability, responsiveness, assurance, empathy, fashionability/variety, price, convenience, merchandise quality and credit card usability should be considered.

When consumers choose healthy foods, they base their buying decisions on health-related food labeling and quality assessment of taste, health, and price. Moreover, both purchase experience and opinions of family and friends affect consumer choices. Focusing on these points, this study examined the effects of health-related food labeling on consumer choices by adding two variables-quality assessment of taste, health, and price and purchase experience-to the model of the theory of planned behavior. We also used structural equation modeling to test our hypotheses. In the study, health-related food labeling includes organic labeling, nutrient claims, and food additive labeling. We conducted a mail survey among 300 married women who buy cheese slices for their children more than once a month. It was discovered that health-related food labeling positively affected the level of quality assessment of taste, health, and price, and consequently led to positive attitudes and purchase intentions. Particularly, health-related food labeling positively influenced attitude toward using products without assessing the quality of taste, health, and price. The level of quality assessment of price positively affected attitude toward using and purchasing products, and purchase experience positively affected attitude toward using and purchasing products, and purchase intentions. The relationship between attitude to purchasing products and purchase intentions was the most positive, and the relationship between perceived behavioral control and purchase intentions was not significant. Overall, this study essentially contributes to the development of a theoretical framework of food labeling and consumer choices, which includes quality assessment of taste, health, and price and purchase experience, by using the theory of planned behavior.

As the broadband network are being deployed recently, the IPTV (Internet Protocol TV) has appeared and become a most representative service that incorporates audio, video, etc. In spite of the long-period efforts, however, no standardized method exists to measure and evaluate the quality of video that is experienced through TV in the customer's premises. Therefore, before developing a method to measure and evaluate the quality of experience (QoE) for video that is the ultimate goal, this paper reviews the outcomes from the past standardization activities and drive a few important implications that would be reflected to the method to measure and evaluate QoE for video.

Purpose: The purpose of this study is to examine the Hawthorne effect on healthcare service process innovation, by investing the difference between checklist items of patients and doctors on direct clinical observations (DCO) and the retrospective clinical review (RCR). Methods: The data set consisted of 30 patients and 30 doctors respondents. T-tests were used to perform a comparative analysis of DCO and RCR items between patients and doctors by pre and post examinations. Results: The results indicate that there was a difference between the non-prior notice checklist items of the patients and doctors, while there was no difference of the post-examination checklist items between the patients and doctors. Conclusion: This study provides useful information and can be applied to the improvement of patient experience through healthcare service process innovation. The results of this study also offer practical insights about how hospitals can motivate providers to participate in healthcare service process for improved quality care by the Hawthorne effect. The study contributes to the existing knowledge of the Hawthorne effect for effective strategies for providing quality care.

Video streaming services make up a large proportion of Internet traffic on both fixed and mobile access throughout the world. Adaptive streaming allows for dynamical adaptation of the bitrate with varying network conditions, to guarantee the best user experience. Adaptive bitrate algorithms face a significant challenge in correctly estimating the throughput as it varies widely over time. In this paper, we first evaluate the throughput estimation techniques and show that the method that we have used offers stable response to throughput fluctuations while maintaining a stable playback buffer. Then, we propose an adaptive bitrate scheme that intelligently selects the video bitrates based on the estimated throughput and buffer occupancy. We show that the proposed scheme improves viewing experience by achieving a high video rate without taking unnecessary risks and by minimizing the frequency of changes in the video quality. Furthermore, we show that it offers a stable response to short-term fluctuations and responds swiftly to large fluctuations. We evaluate our algorithm for both constant bitrate (CBR) and variable bitrate (VBR) video content by taking into account the segment sizes and show that it significantly improves the quality of video streaming.

Purpose: To examine whether the Patient Experience Assessment (PEA) has led to perceptible changes at the ground level of health care, as a way of evaluating PEA as a policy intervention for quality improvement. Methods: Four focus group discussions (FGDs) were conducted, each comprising six to eight participants who were employees responsible for patient experience at their respective hospitals. The primary focus of the FGDs was on questions such as: 1) How do hospitals respond to PEA? 2) What significant changes were observed after the implementation of PEA? 3) What were the unintended consequences of implementing PEA, if any? 4) What areas of improvement have been identified for maximizing the potential of PEA? Results: Two broad themes emerged out of the FGDs: changes observed post implementation of PEA, and areas for improvement of PEA. Four significant changes were reported by participants: changes in perception and attitude regarding patient experience in hospital employees, increased active involvement by the hospital leadership, enhanced efforts to improve patient experience, and increased cooperation between such activities. Furthermore, eight areas of improvement were identified, which have been grouped in three categories: improving the process of data collection for PEA, introducing additional catalysts to facilitate further changes, and paying attention to structure- and patient-level constraints that must be addressed in parallel. Conclusion: The implementation of PEA led to perceptible changes within hospitals, which implies that it can serve as an effective catalyst for improving patient experience. A number of areas of improvement that would aid in maximizing the potential of PEA were also identified.

Purpose: This study examines the structural relationship between perceived quality, relationship quality, and revisit intention in the context of coffee shop. In this model, perceived quality consists of product, service, and experience quality, and relationship quality consists of satisfaction, trust, and commitment, and performance consists of revisit intention. More specially, this study identifies whether perceived quality plays a mediating role in the relationship between perceived quality and relationship quality and the direct/indirect effects of perceive quality on intention to revisit. Research design, data and methodology: The survey was conducted from September 1 to 30, 2019. The data were collected from 320 respondents and analyzed using structural equation modeling (SEM) with AMOS program. Results: The findings are as follows. First, quality perception of coffee specialty stores had a statistically positive effect on relationship quality, indicating supports H1. Therefore, customers can know that they are aware of the quality of coffee specialty stores, including quality of service and experience as well as products, and that they form relationship quality with coffee specialty stores. Second, relationship quality between coffee shops and customers had a significant positive effect on performance. Thus, H2 was supported. The results show that if the coffee shop does not consider relationship quality as important, customer loyalty decreases, the number of customers decreases, and the number of customers who switch to another coffee shop increases, which can lead to a threat to the coffee shop. Third, in the case of hypothesis H3, it was found that there was a partial mediating effect of satisfaction and trust between quality perception and reuse intention of coffee specialty stores, so hypothesis H3 was partially supported. As commitment appears to have no mediating effect, it can be said that customers who use coffee shops are not only difficult to maintain as regular customers of a particular coffee shop, but also have ample room to move to other coffee shops. Conclusions: Although many scholars point out the importance of service quality, few studies were conducted in the context of the Korean food service industry (including coffee shops). From this perspective, this study tested several hypotheses that the quality (product, service, experience) perceived by customers can have a positive effect on relationship quality and performance (re-visit intention), either directly or indirectly. The findings of this study demonstrate that if the manager of a coffee shop understands the characteristics of quality perceived by customers and the role of relationship quality, the effect of quality perceptions on customers can be maximized in order to maintain the relationship with customers.

The purposes of this study were to classify respondents by their fashion lifestyle and to investigate the differences in cognition, attitude and purchasing experience of SPA brands among fashion lifestyle groups. The convenience sample was drawn from females between the ages of 20 and 39 who lived in Daegu and Gyeongbuk regions from November $1^{st}$ and $15^{th}$ 2012. Descriptive statistics, cluster analysis, ANOVA, Tukey test, and ${\chi}^2$ test were applied to analyze data from 255 respondents. Four clusters (fashion-oriented group, fashion indifferent group, conservative individuality-oriented group, conservative practicality-oriented group) were developed by 16 fashion lifestyle items. The attitude toward SPA brand was classified by six factors(fashionability/variety, good location, good quality, diverse promotions, low price, limited number of merchandise, sales person's information). There were significant differences in cognition, five attitude factors (fashionability/variety, good location, good quality, low price, limited number of merchandise) and purchasing experience of SPA brands among types of fashion lifestyle. While the fashion-oriented group had the highest scores of cognition, attitude and purchasing experience of SPA brands, the fashion indifferent group or the conservative practicality-oriented group had the lowest scores. There were significant differences in age and marital status among the four groups while there were no significant differences in marital status, family monthly income, and job.
