책 향기에 빠져보는 하루 서울시내 북 카페가 우리를 부른다. 예전의 카페가 친구끼리 연인끼리 둘 이상이 같이 와서 웃고 떠들며 혹은 조용한 대화를 나누던 공간이었다면 요즘의 카페 특히, 북카페는 혼자가 더 자연스럽다. 편안한 소파는 물론 좌석 온돌마루에 푹신한 방석이 있는가 하면, 족욕을 즐길 수 있는 곳까지 다양한 서울의 카페. 북 카페는 요즘 서울카페의 대세를 이룰 태세다.

This study was performed to survey and evaluate the contents of caffeine in commercial palatability foods by HPLC. The contents of caffeine in commercial palatability foods were 9.0~49.2 mg in black tea, 35.9~141.4 mg in coffee, 12.4~48.0 mg in green tea, 7.1 ~16.5 mg in brown rice green tea, 22.8 mg in cocoa tea, 10.3~25.0 mg in cola and 10.0~48.2 mg in ice bar(coffee) respectively. The contents of caffeine extracted from black tea, coffee(roasted beans) and green tea were rapidly increased for five minutes from the extraction initiation, and were not nearly changed after ten minutes. Moreover, the caffeine contents were increased until 10$0^{\circ}C$ of extraction temperature.

In this study, we investigate the effect of twenties female caffeine addiction on cardiorespiratory capacity. For this study, we divided 35 female students at H university into caffeine addict group(n=17) and none caffeine addict group(n=18). Measure maximal oxygen uptake, maximal energy consumption and METs using Cycle Ergometer to assess cardiac capacity. Measure peak inspiratory pressure, peak inspiratory flow rate, peak inspiratory capacity, average inspiratory pressure, average inspiratory flow rate, average inspiratory capacity using Power Breathe K5 to assess respiratory capacity. As a result, cardiac capacity showed a statistically significant decrease in maximal oxgen uptake and METs compared caffeine addict group to none caffeine addict group(p<.001). respiratory capacity showed a statistically significant decrease in peak inspiratory pressure(p<.05), peak inspiratory flow rate(p<.01), average inspiratory pressure(p<.01), average inspiratory flow rate(p<.01), compared caffeine addict group to none caffeine addict group. Combining the results of the study, we could see that caffeine addiction reduces the cardiorespiratory capacity in twenties female. Therefore, it could be used as a basis date to prevent caffeine addiction for twenties female.

This study was conducted in order to identify the present condition of caffeinated drinks intake including energy drink. Concretely, It was investigated about stress degree, study attitude, sleeping hours by intake degree of caffeinated drinks. Descriptive survey research was designed. A total of 371 students in M university was participated. Data were collected through a questionnaire (from October 22, 2012. to October 26, 2012). The data were analyzed by t-test, ANOVA, scheffe's test, using the SPSS version 17.0. There were no significant differences between caffeinated drinks intake's degree including energy drink. Most of students thought caffeinated drinks intake have an effect on their health. Intake time of caffeinated drinks was before or after studying or sleepy. Caffeinated drinks intaked mostly alone. Intake causes of canned coffee or energy drink was sleepy and coffee mix, black coffee, coffee flavored milk and green tea was good taste. Stress degree, study attitude, sleeping hours by intake degree of caffeinated drinks were no significant effects between canned coffee, coffee mix, black coffee, green tea and energy drink. But, stress degree by intake degree of coffee flavored milk was significant low when it intakes more than once a day, sleeping hours was significant long when it was nondrinking.

본 연구에서는 카페 비즈니스에서 중요한 서비스 품질의 여러 요인 중 카페의 사회문화성이 새로운 커피 비즈니스의 주요 특성으로 대두됨을 인식하여 이를 통해 카페의 이미지와 브랜드 충성도의 향상방안을 모색해보고자 함에 본 연구의 목적이다. 커피 전문점 중 전문브랜드와, 지역브랜드, 개인카페를 중심으로 설문을 통해 이를 분석한 결과, 카페 서비스품질 중 사회문화성은 전국 프랜차이즈는 브랜드 충성도를 도리어 낮추는 결과를 주지만 개인카페는 브랜드 충성도를 높이는 요인으로 작용하는 차별된 효과가 나타나 개인카페나 지역프랜차이즈의 카페 비즈니스에서는 전문성이 기반이 되어야만 브랜드 충성도를 향상시킬 수 있으며, 개인카페는 지역 프랜차이즈보다는 더욱 덜 복잡한 서비스 전략이 필요한 것으로 나타났다. 또한 개인카페의 특수한 사항들이 사회문화성을 통한 브랜드 이미지를 향상시키고 이를 통해 브랜드 충성도를 높이는 것을 알 수 있다. 결과적으로 전국 프랜차이즈는 서비스 품질 중 접근성과 확신성을 통해 브랜드 이미지와 브랜드 충성도가 높아지는 전략이 우선적으로 대두되며, 그 외의 서비스 품질들은 충분히 현재의 상태로도 매우 만족스러운 결과인 것으로 나타났다. 반면, 지역 프랜차이즈의 경우는 서비스 품질 중 확신성이 강화되고, 서비스 전문성과 접근성을 통해서 더욱 브랜드 이미지와 브랜드 충성도를 향상시킬 수 있는 전략이 마련되어야 전국 프랜차이즈화 될 수 있는 고객의 인지력을 향상할 수 있는 전략이 모색된다. 반면, 지역기반의 개인카페들은 전국단위의 프랜차이즈보다 전국단위의 프랜차이즈로 나아가기 위해서는 지역기반의 지역프랜차이즈 카페들보다도 전문성 강화가 중요하며, 사회문화성을 강조하는 서비스 전략을 통해 고객들로 하여금 브랜드 충성도를 높이도록 전략화 방안이 필요하다.

본 연구는 간호대학생의 카페인 음료의 섭취실태를 파악하고, 학습 집중력과 수면의 질과의 관계를 확인하기 위한 서술적 조사연구이다. 대상자는 한 달 평균 하루 2.45병의 카페인 음료를 섭취하고 있었고 잠을 쫓기 위한 섭취 이유가 집중력이나 학습능력 향상에 도움을 주는 것보다 수면의 질이 더 낮았고, 하루 2병을 섭취하는 경우가 하루 1병을 섭취하는 경우보다 수면의 질이 더 낮았다. 수면의 질은 카페인 섭취 이유, 학습 집중력과 통계적으로 유의한 양의 상관관계가 있는 것으로 나타났다. 이상의 결과를 바탕으로, 잠을 쫓기 위한 카페인 음료 섭취 및 하루 2병 이상의 카페인 음료 섭취는 수면의 질을 저하 시키므로 카페인 음료 섭취를 자제하고 수면의 질을 높일 수 있는 대안을 마련하여 학습 집중력의 향상을 도모해야 할 것이다.

A survey was carried out regarding university students' recognition of high-caffeine energy drinks in an effort to identify and improve problems as well as provide basic data. Most of the subjects had previous experience of energy drink consumption. Studies showed that most students consumed energy drinks when studying. Regarding frequency of energy drink consumption, most students' responded "1~6 times a year"; female students showed lower frequency of energy drink consumption than male students. Both male and female students used convenience stores to purchase energy drinks. In most cases, students became aware of energy drinks through advertisements on TV, radio, newspapers, and magazines. The most important factor affecting their energy drink purchase and consumption status was taste. The most frequent adverse effect they experienced after drinking an energy drink was unusual heart-pounding, whereas the biggest problem caused by energy drink consumption was addiction. This study indicates that students should have a better understanding of the problems associated with excessive and prolonged high-caffeine intake. In addition, instructions for proper purchasing and consumption of high-caffeine energy drinks should be provided as well as education and campaigns concerning symptoms caused by high-caffeine energy drink consumption so that students may refrain from excessive consumption. Further, civil organizations and the government need to devise effective measures for proper regulation of high-caffeine energy drink consumption.

Purpose: The purpose of this cross-sectional study was to investigate intake-related factors of energy drinks and educational needs regarding energy drinks in female high school students. Methods: Subjects were 340 female high school students in Incheon, and data were collected using self-administered questionnaires. Statistical analysis was performed using the SPSS 20.0 program. Results: Subjects who had drunk energy drinks were 74.3% (249 subjects) of all subjects. The first time they drank an energy drink was significantly associated with grade (p < 0.05). In 75.1% of 249 subjects who had drunk energy drinks, the places for buying energy drinks were supermarkets and convenience stores near their homes. For the effects of energy drink intake, sleeplessness (44.6%) and no effect (41.7%) were cited, and 24.5% experienced side effects such as palpitation, tremors, etc. The scores for self-diagnosis of caffeine addiction were significantly higher in the low weight group compared to the overweight group (p < 0.05). The degree of caffeine addiction was significantly associated with effects of energy drink intake (p < 0.001) and type of side effects (p < 0.001). Willingness to stop consuming energy drinks (p < 0.001) and necessity of nutrition education about energy drinks (p < 0.05) were significantly lower in the caffeine addiction group compared to the general group. About 75.0% of subjects wanted to be educated about the side effects of energy drinks and caffeine. Conclusion: This study shows that female high school students need proper education about the effects of intake of energy drinks. Therefore, guidelines and a nutrition education program right intake of energy drinks should be provided as well as campaigns concerning the side effects of energy drinks and caffeine in female high school students.

커피를 마시지 않는 우리 아이가 카페인을 과하게 섭취하고 있다면? 믿지 못하는 부모들이 많은데, 사실일 수 있다. 아이들이 즐겨 찾는 청량음료, 초콜릿을 비롯해 최근 히트하고 있는 이른바 에너지음료까지, 카페인 함유량이 만만치 않다. 카페인은 적절히 섭취하면 피로를 줄이고 집중력을 높이지만, 과다 섭취하면 건강을 해치고 심각한 중독으로 이어질 수 있다. 그렇다면 우리 아이에게 적당한 카페인 하루 섭취량은 얼마일까.
