The purpose of this study was to analyze the general characteristics of coffee house consumers as well as the importance and satisfaction of selection attributes of specialty coffee houses according to length of coffee education period. Applicants in the Gwangju and Jeonnam area who had finished their Barista 2 grade certificate examination participated in a survey on March 12, 2011. Further, university students living in Gwangju participated as subjects who had never experienced coffee education from March 15 to March 31, 2011. Two-hundred and one subjects participated in the survey, and 184 questionnaires were used for analysis. Regardless of coffee education experience, quality of coffee was important, but higher educated subjects showed the lowest satisfaction of coffee from a coffee house (p<0.01) in terms of attributes such as freshness of coffee beans (p<0.01) and overall taste (p<0.01). Further, subjects who received no or little education demonstrated high correlation between importance/satisfaction of 'brand' and 'employee' compared to subjects who studied more than 2 semesters. These results provide future coffee house entrepreneurs and baristas with market information and marketing strategies for understanding customers' coffee house selection attributes.

This study was performed to investigate the consumption of coffee beverages and energy contribution ratios of coffee beverages and accompanying snacks by college students in Deajeon City and Chungnam Province in Korea. Questionnaire survey, dietary survey, and snack survey using food record method during 3-days were carried out. As a result, we found that 86.9% of male students and 75.6% of female students consumed coffee beverages usually, with no differences between the two groups. However, the frequency of coffee beverages consumed by female students out-numbered that of male students by 1 cup a day to 1-2 cups a week (p<0.05). Furthermore, male students most likely consumed coffee beverages at schools or academies, but female students consumed them at coffee shops (p<0.01). The reasons male students gave to consume coffee beverages were for scent, taste, fatigue, and to stay awake. Similarly, the reasons female students gave to consume coffee beverages were for scent, taste, habit, and to stay awake (p<0.01). Fully 58.1% of male students and 80.0% of female students ate snacks along with coffee beverages (p<0.01). Most male students substituted a coffee beverage and accompanying snack for a regular meal once a month. Female students were doing it at most 2-3 times a month (p<0.05). The mean daily dietary energy intake of male students was 1,924 kcal/d, and of female students was 1,518 kcal/d (p<0.001), which both were below the estimated energy requirements. Male students obtained 285.6 kcal/d and female students obtained 289.5 kcal/d from coffee beverages and accompanying snacks. There was a significant different in dietary intake of energy (p<0.05), calcium, and iron (p<0.001) for each ratio of reference intake between male and female students. The students who ate larger amounts of coffee beverages and accompanying snacks consumed less dietary energy, protein, calcium, and iron, respectively (p<0.05). These results show that many students consume coffee beverages regularly and obtain large amounts of energy from coffee beverages and accompanying snacks. It also shows that student's dietary nutrient intake tends to be poorer, as he or she obtains more energy from coffee beverages and accompanying snacks. Therefore, it is critical to monitor the influence of consumption of coffee beverages and accompanying snacks on the dietary nutrient intakes and health of college students, and to provide nutrition education about the proper consumption of coffee beverages and accompanying snacks based on scientific evidence.

This study was conducted to develop fabrics using non-toxic and eco-friendly natural dyes made from curcuma and coffee extract. The natural dyes were applied to non-printed cotton fabrics using the dip dyeing method, and the pattern was hand-printed onto the dyed fabrics to make dyed printed-fabrics. The four types of developed fabric samples were compared to analyze the effects of the dyeing materials and printing on the hygienic properties of curcuma- and coffee-dyed fabrics. The findings were as follows. First, air permeability of both curcuma- and coffee-dyed fabrics was greatly affected by the presence of patterns, although the type of dye did not seem to have an effect. Printing greatly reduced air permeability of the fabric, and coffee-dyed fabric showed greater reduction of dyeing method than curcuma-dyed fabric. Moisture regain also tended to decrease with printing, but the change was much smaller compared to air permeability. Second, increased UV blockage was observed in curcuma- and coffee-dyed fabrics with patterns compared to non-printed fabrics, showing that printing enhanced UV blocking. Third, deodorization rate tended to increase sharply for both curcuma- and coffee-dyed fabrics until 30 minutes and gradually increased thereafter to yield 30% for curcuma and 50% for coffee at 120 minutes, demonstrating higher deodorization of coffee dye. Coffee-dyed fabric showed an antibacterial rate about twice as high as that of curcuma-dyed fabric, and the observed data suggest that curcuma-dyed fabric had an insignificant level of antibiosis. Fourth, printing significantly enhanced wash, sunlight, and compound colorfastness of the two types of dyed fabrics. The effect of printing was most dramatic on sunlight and compound colorfastness, which are aspects in which natural dyed fabrics perform poorly in general. Eventually, the development and application of biologically- and environmentally-friendly fabrics with natural dyes correspond with increased interest towards the wellness and healthy attitudes of modern society.

An efficient molecular breeding technique for coffee plants was developed. In order to produce transgenic coffee plants, we established a model transformation procedure via Agrobacterium method. We isolated a gene encoding a protein possessing 7-methylxanthine methyltransferase (theobromine synthase) activity, and it was designated as Coffea arabica 7-methylxanthine methyl transferase; CaMXMT. Using this clone, we produced transgenic coffee plants, in which the expression of CaMXMT is suppressed by double-stranded RNA interference (RNAi) andlor anti-sense methods. The expression pattern of CaMXMT was analyzed by reverse transcription-PCR method and we found that, in the transformed cell lines, the level of transcripts were obviously suppressed by RNAi. The endogenous level of caffeine in the transformed cells was dramatically reduced in comparison with non-transformed cells.
