To predict the transonic buffet onset for a supercritical airfoil with shock-boundary layer interactions, a practical steady approach has been proposed. In this study, it is assumed that the airfoil flow is steady even when buffet onset occurs. Steady Navier-Stokes computations are performed on the supercritical airfoil. Using the aerodynamic parameters calculated from Navier-Stokes solver, various steady approaches for predicting buffet onset are discussed. Among the various steady approaches considered in this study, Thomas' criterion based on Navier-Stokes computation has shown to be the most appropriate indicator of identifying the buffet onset for a supercritical airfoil with shock-boundary layer interactions. Good agreements have been obtained compared with the results of unsteady transonic wind tunnel tests. The present method is shown to be reliable and useful for transonic buffet onset for a supercritical airfoil with shock-boundary layer interactions in terms of practical engineering viewpoint.

This study investigated the hotel buffet restaurant's service quality, emotional reaction of customer, recommendation intention, and defection intention. The survey was conducted from January 3 to February 7 in 2011, and 400 respondents were used in the data analysis. As a results of this study, the hotel buffet restaurant's service quality was classified by the interaction, outcome, and physical environment quality. The emotional reaction of hotel buffet restaurant's customer was classified by the positive and negative emotion. The all factors of hotel buffet restaurant's service quality had a positive impact on positive emotion, while it had a negative impact on negative emotion. The positive emotion reaction of hotel buffet restaurant's customer had a positive impact on the recommendation intention, while the negative emotion had a negative impact on the recommendation intention. And the negative emotion had a positive impact on the defection intention in hotel buffet restaurants. In addition, there were partially differences in the service quality and emotional reaction by general characteristics. There were significant differences in the recommendation intention by marriage status and monthly income. Therefore, the hotel buffet restaurants have to design a strategy of service for increasing customer's positive emotion and recommendation intention.

Up to these days, hotels are assumed to compete each other. Due to the spread of high quality the hotel buffet restaurants have begun to face an intensive competition. Hotel Buffet Restaurant have become the more competitive along with fund, good price, service, quality food, and management know-how. It causes the hotel restaurants confront with management difficulties. In order to overcome the management difficulties, hotel buffet restaurants have to improve their marketing abilities and especially to improve their service quality. For this, it is necessary for hotel buffet restaurants to investigate how their service providers and receivers recognize their service quality. In this research, we examined the cognitive three types of cognitive gaps among customers, service providers, and managers both on the service quality and on the positioning of hotel buffet restaurants. Their cognitive gaps proved negatively correlated with hotel's performance. This research suggests the fellowing findings. Firstly, the competitiveness of hotel buffet restaurant depends on the accurate communication and consensus among managers, service providers, and customers. Secondly, using the information about cognitive gaps recognized, each hotel buffet restaurant should develop concrete marketing plans and strategies with a careful consideration about its current competitive position and management condition.

The Korean buffet restaurant, which was developed by combining the Korean food and a buffet, allows a large menu to be enjoyed at a reasonable price and has become popular with men and women, young and old, and become a new type of eating out. This study examined the effects of the waiting time management and menu quality on the customer satisfaction and re-visit intention in a Korean buffet restaurant to help quality improvement and development of Korean buffet restaurants. The customer satisfaction and re-visit intention only had a significant effect on the staff attitude toward waiting time. Hygiene, sensory factor, and variety of menu quality were significantly related to customer satisfaction and re-visit intention, respectively. In addition, satisfaction with food and service had a significant effect on the re-visit intention and customer satisfaction. Therefore, it is important to establish a virtuous cycle structure that will improve the re-visit intention by satisfying customers through waiting time management and menu quality for the development of Korean buffet restaurants.

For the hotel industry, the situations having difficulties in management are becoming we planed by the rises of the cost and labor costs, the imbalance between supply and demand, stiffening competitions between the hotels. Therefore, there has been a plan for a great change to attract customers, escaping from the existing form of management in order to secure competitive powers in the food and beverage field. For that purpose, we plan to investigate into the preference of buffet restaurants in ten 5star hotels in Seoul. By the analysis, we also plan to present the menu concepts that stand out and are preferred by the customers in managing semi-buffet restaurants. Therefore, the linear and planar coordinate values of the H Hotels and I Hotels came out both positive(+) as results of a similarity analysis using MOS, we can predict that they would be positioning on the same dimension. Furthermore we can predict that the menu of antipasto, sushi, sashimi and desserts would be positioning on the same dimension as a result of analysis of the most preferred menu by customers for each station in managing a semi-buffet restaurant. Based on these results, there must be continuous supervision over the menu of buffet restaurants.
