The purpose of this experimental study is to investigate and compare the vowel lengths of the English diphthongs, /eɪ/ and /aɪ/, and the front low vowel /æ/ among English-speaking natives with Korean college students using the Praat software program. To do this English sentences were uttered and recorded by twelve subjects, six Korean subjects and six English-speaking native subjects. All the subjects are female and their age ranges from 23 to 35. Acoustic features(duration) were measured from a sound spectrogram with the help of the Praat software program and analyzed through statistical analysis. Results showed that the vowel lengths of the English diphthongs and the front low vowel between native English speakers and Korean collegians were different. In the pronunciation of the diphthongs /eɪ/ and /aɪ/, Korean subjects pronounced longer than native subjects did, but the difference was not significant. However, in the pronunciation of the English front low vowel /æ/, native subjects pronounced significantly longer than Korean subjects did. From the data of the overall sum of words and vowels between the two subject groups, we were able to find out that the differences of lengths of both the three words and the two diphthongs /eɪ/ and /aɪ/ were not significant, but those of /æ/ were significant.

This study was conducted to investigate the dietary behaviors and health-related lifestyles, according to exercise habits, of female university students in the Jeonju area. Self-administered questionnaires were collected from 285 students, and the statistical data analysis was completed using the SPSS v. 10.0 program. The results are summarized as follows. The weight, height, and BMI averages of the regular exercise and non-exercise groups were 53.05 kg, 162.46 cm, and 20.23, and 50.81 kg, 161.46 cm, and 19.48, respectively. The breakfast skipping ratio was higher in the non-exercise group than the exercise group. More than 72% of the exercise and 71% of the non-exercise group responded to regularly having lunch at the university canteens or restaurants around campus. Approximately 70% of the exercise and 71% of the non-exercise group responded to having dinner irregularly, which was mainly caused by reasons such as 'irregularity of life style' and 'appointments with friends'. The snack intake ratios of the exercise and non-exercise groups were high, but the exercise group ate more fruit, yogurt, and milk than the non-exercise group. The favorite sports of the exercise group were 'walk(jogging)', 'yoga', 'bicycle,' 'swim,' etc. In particular, 5.3% of the exercise group had ridden a bicycle to the university. More than 97% of the students were non-smokers. About 14% of the exercise and 15% of the non-exercise group rank alcohol once or twice a week. The exercise group did not show exceptional health-oriented dietary behaviors in comparison to the non-exorcise group. Therefore, an exercise-oriented nutrition education program would be beneficial to the students, in order to improve their dietary behaviors and health-related lifestyles.

This study investigates the purchasing and wearing conditions of wetsuits, and analyzes consumer awareness on wetsuit functional factors between domestic and imported brands. This research provides basic information on presenting competitiveness and developing suitable wetsuits for the Korean body shape through an investigation of a size system. An in-depth interview was conducted to consider consumer awareness with 10 persons of different levels of scuba diving experience. The survey variables consist of classified suggestion of inquires for functional factors and size systems. We distributed 80 questionnaires to scuba diving club members; subsequently, a total of 66 usable data sets were coded for statistical analysis through SPSS WIN 18.0. The result shows that respondents preferred imported ready-to-wear brands, whereas national ready-to-wear brands were purchased less often. However, the difference in customer awareness of functional factors between domestic and imported brands was not significant. In evaluating the size system of six brands (including three domestic and three imported brands), wetsuits of domestic brands were better fitted to the Korean body shape than imported brands; however, competitiveness has been hindered by public perception that domestic brands imitate imported brands. The results suggest that domestic brands can strengthen their competitiveness through promoting a lower price and size suited to Koreans while trying to change public perception as imitators of imported brands.
