This article analysed the curricula of the tourism related majors, and proposed ways to enhance intercultural communication competence of tourism students. As the first step, the concept of the intercultural communication competence was explored through an extensive literature review. Then the tourism curricula of the universities in Korea were analyzed from the perspective of intercultural communication. The analysis of the curricula revealed that there were very few courses which focused on intercultural communication, and tourism English could take the role of teaching intercultural communication. Based on the analysis of tourism English curricula, suggestions were made in relation to course objectives, curriculum development, textbook development and the research needs to obtain a status as the English for Specific Purposes(ESP). Limitations of the study were also presented.

Twelve male students (major in physical education; non-coffee drinkers; 6 endurance athletes; 6 non-athletes) were studied to determine the effects of caffeine, and Glucose feedings on submaximal endurance performance. Each subject performed three submaximal cycling trials at an absolute intensity of 900kpm. The trials were randomized to negate any possible order or training effects. For the caffeine trial, 2.5 mg/kg body weight of caffeine in 250ml of artificially sweetened barley tea was ingested twice one hour and 30.min prior to the ride. In the glucose trial, 0.5g/kg. body weight of glucose in 250m1 of barley tea was ingested twice one hour and 30 min prior to the ride. During the control trial, 250ml of artificially sweetened barley tea was ingested twice one hour and 30 min prior to the ride. obtained data from the three trials were analyzed with one way ANOVA for repeated measures design. Significant differences between means were located using a multivariate comparison. The level of significance was established at p<0. 05. The results were summerized as follows : Ingestion of glucose elevated blood glucose and insulin levels at rest , but no significant differences in blood glucose concentration were found between the three trials . Glucose ingestion resulted in rapid hypoglycemia and inhibition of FFA mobilization during exercise. Caffeine ingestion increased significantly in VE, Vo2 and plasma osmolarity during the exercise. But caffeine ingestion failed to elevate plasma FFA concentration, HR and blood pressure significantly. Glucose or caffeine ingestion did not change in blood lactate, Hb , plasma Na+ concentration, Hit and RQ during exercise. In the above results, It was suggested that ingestion of caffeine prior to the exercise fail to increase in lipid metabolism during exorcise and may have some detrimental effects on endurance performance besides psychological ergogenic effect of caffeine, and that glucose ingestion prior to the exercise elevate blood glucose and insulin level at rest but may have detrimental effect of endurance performance because of rapid hypoglycemia caused by hyperinsulinemia.
