To provide efficient video streaming service over a wireless networks, the rate adaptation scheme should be applied at the low layer and the quality adaptation scheme should be considered at the high layer. In this paper, we propose a new cross-layer design which includes rate adaptation scheme at the MAC/PHY layers and quality control at the application layer. Proposed rate adaptation scheme improves the wireless channel utilization by transmitting the consecutive frames and selects optimal transmission mode by calculating the goodputs for each transmission mode. Based on selected transmission mode, the rate adaptation scheme calculates the rate limits and informs that to the application layer. Then the video streaming application utilizes this rate limits to adjust the quality of the video stream. Through performance evaluations, we prove that our cross-layer design improves the quality of the wireless video streaming service by means of the proposed rate adaptation scheme.

The purpose of this study is to find the effect of restaurant brand image upon service quality, price acceptability, and revisit intention, and to propose the importance of brand image to operators and managers who manage restaurants. To accomplish the purpose of this study, sampling was taken among customers who visit six deluxe hotels and six family restaurants in Seoul. Six hundreds questionnaires were distributed to each hotel and restaurant and 487 valid samples were selected for statistical analysis. The questionnaire consists of 77 items about demographical characteristics, brand image, service quality, revisit intention, price acceptability, and spending patterns. SPSS WIN 10.0 was used for statistical analysis. A research model was built up and three null hypotheses were established. Based on theses research model and three null hypotheses, the test was conducted, and the results are as follows. Brand image has an effect upon service quality, and furthermore this can be preceding variable of service quality. Also Service quality has an effect upon price acceptability and revisit intention.

The spread of the COVID-19 pandemic has been increasing non-face-to-face activities; as a result, this has resulted in the number of individuals obtaining medical information from the websites and mobile contents of medical institutions increasing. The study conducted the structural equation modeling to test hypotheses; as a result, all sub-factors of e-service quality of small medical clinic websites and mobile contents, usability, security, responsiveness, design, and information, had a significant positive effect on relationship quality, and relationship quality had a significant positive effect on e-Loyalty. Moreover, the structural equation model showed a good model fit, χ²/df of 2.021, NFI of .954, TLI of .969, CFI of .976, RMSEA of .046. Future research is suggested to study relationship quality by developing a system able to quickly and accurately respond to websites and mobile contents users; furthermore, improving e-service quality and relationship quality is likely to strengthen e-loyalty.

This study aims to the recognize the importance of uniform design and provide empirical data to companies after getting the effects of uniform design in cosmetics companies on service quality perception and customer satisfaction. For this, a preliminary survey was conducted against 30 college women (aged 20s) from 'K' University, and effective samples were obtained from 250 people. In terms of a research method, collected data were coded and analyzed using SPSS. The respondents' characteristics were analyzed using descriptive statistics. For reliability analysis, Cronbach's ${\alpha}$ was used. For a validity test, factor analysis was performed. In addition, correlation analysis was carried out to examine multicollinearity among variables. The analysis results found that the characteristics of uniform design have a positive effect on service quality and customer satisfaction. Among the characteristic of uniform design, however, functionality wasn't confirmed in a relational test. This kind of result was obtained because the uniform was mostly analyzed from customers' perspective, not from the wearer's standpoint. It is expected that the study results would be helpful in establishing brand identity through the improvement of the importance of uniform design.

The participants were women in their 20s to 50s with experiences of purchasing apparel from major department stores. A total of 324 survey responses were used for the final analysis. The data were analyzed using factors analysis, reliability analysis, and multiple regression analysis with PASW 18.0. The results were as follows. First, the department store personality was composed of 3 factors; prestige, passion, sincerity. Service quality factors were defined as tangibility, responsiveness, and empathy. Second, the three dimensions of brand personality-prestige, passion and sincerity turned out to be influential factors affecting the customers' revisiting intention and recommendation intention. Also, tangibility and responsiveness of service quality factors had a significant influence on their revisiting intention, whereas tangibility, responsiveness and empathy factors had a significant influence on their recommendation intention. Third, the sub-dimensions of store personality and service quality had a different influence on the customers' revisiting intention and recommendation intention according to the department store brand.
