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.

소비자는 건강식품을 구매할 때, 건강관련 식품표시 뿐 아니라, 제품의 맛과 가격을 함께 고려하고, 과거구매경험과 주변 사람들의 의견에 영향을 받는다. 본 연구는 이러한 점에 초점을 맞추어 계획적 행동이론의 모형에 맛, 건강 기대도와 가격수용도 등의 구매 전 품질평가 변수와 제품사용태도, 과거구매경험 변수를 추가하고, 구조방정식모형 분석을 통해 제품 선택 시 건강관련 식품표시의 영향을 살펴보았다. 건강관련 식품표시는 유기가공표시, 영양강조표시, 식품첨가물표시로 구성하였고, 자녀용으로 슬라이스 치즈를 월 1회이상 구입하는 기혼여성 300명을 대상으로 온라인으로 설문조사를 수행하였다. 본 연구결과, 건강관련 식품표시에 대한 인식은 맛과 건강에 대한 기대와 가격수용도를 높여 제품사용 및 구매태도와 구매의도에 긍정적 영향을 미쳤다. 특히, 건강관련 식품표시를 인식하는 것만으로도 별도의 품질평가 없이 제품사용에 대한 호의적 태도가 형성되는 것으로 나타났다. 가격수용도는 제품사용 및 구매태도에, 과거구매경험은 제품사용 및 구매태도와 구매의도에 직접적으로 정적인 영향을 미쳐 계획적 행동이론 확장모형의 주요 변수로 파악되었다. 또한, 구매의도에 가장 큰 영향을 미치는 변수는 제품구매태도로 나타났고, 지각된 행동통제의 구매의도에 대한 영향은 유의하지 않았다. 본 연구는 계획적 행동이론을 기반으로 맛, 가격 등 구매 전 품질평가와 과거구매경험 변수를 포함하여 건강관련 식품표시와 제품선택에 대한 새로운 이론적 틀을 구축하였다는 점에서 의의가 크다.

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.
