This study aimed to classify attendants of a wine training institute according to loyalty for wine training service program and to deduce the core managing points in a wine training program by IPA (Importance-Performance Analysis). Self-administered questionnaires were collected from 192 trainees and statistical data analysis completed using SPSS ver. 18.0. As a result of clustering analysis based on trainee loyalty from both attitude and behavioral perspectives, four classification groups were identified: a "genuine" loyalty group, a "latent" loyalty group, a "mendacious" loyalty group, and a "low" loyalty group. For the genuine loyalty group, the importance of total service quality was 4.32 on average whereas the performance was measured as 4.22; thus there was little difference between importance to quality and performance. However, for the other three groups, especially the low loyalty group, there were significant wide gaps between importance to quality and performance. According to IPA, different service quality items were posted on the 'Focus here' quadrant (a domain with high service quality importance but low performance) by group, while the other three quadrants had several common items regardless of the group. Finally, the core quality managing points were different depending on the level of trainee loyalty. Therefore, it is necessary to plan and conduct a wine training program that reflects the characteristics and needs of its students, which will lead to a differentiated management strategy according to the level of loyalty.

The purpose of this study was to analyze the effects of quality factors on value, satisfaction and loyalty in a wine training program. The results of this study can be summarized as follows: Structural verification of the wine training program loyalty model showed that the quality of the wine training program positively affected both value (p<0.001) and satisfaction (p<0.001). Further, the value of the wine training program positively affected satisfaction (p<0.01), which in turn positively influenced loyalty (p<0.001). The quality of the wine training program was presented as solicitude for students, textbook and curriculum, qualification and confidence of lecturer and staff, and training quality, whereas the value of the program was composed of sense of belonging, promotion of self-esteem, good impression on others, and improvement of social status. Therefore, the wine training institute's intensive management of the quality and value of the program could induce students' loyalty by enhancing satisfaction for the wine training program.
