This study was conducted in order to identify consumption and experience of adverse effects of high-caffeine energy drink among high school students. This study was a descriptive survey including 245 students in D city. Data were analyzed using descriptive statistics and ${\chi}^2$ test. In the results, 79.5% of the students had previous experience of energy drink consumption. 50.6% of students were experienced adverse effects, mainly palpitation. Among the general characteristics, there was a significant difference according to the experience of high-caffeine energy drink consumption depending on monthly allowance(p=.019) and drinking(p=.033), and a significant difference from adverse effects depending on gender(p=.001) and health condition(p=.006). Also, there was a significant difference according to the experience of adverse effects depending on drinking reason(p=.040) and drinking time(p=.005). After, policy measures are needed to limit the sale of high-caffeine energy drinks and continuous health education is needed to foster the ability of students to control themselves.

Objectives: This study sought to assess the prevalence and duration of weight-control or health functional food use, associated weight-control behavior, perception, and knowledge among university students. Methods: The subjects were 442 university students in Cheonju, Korea, and data was collected by a self-administered questionnaire. Both χ2 and t-tests were conducted for categorical and mean comparisons. Results: An estimated 62.7% (female 69.0%, male 54.8%) had ever attempted weight-control. Among these, an estimated 59.2% of females and 38.9% of males had used weight-control or health functional foods with significant gender difference. The weight-control foods commonly used included chicken breast, protein powder, low-fat milk and soymilk, and meal replacement drinks, while garcinia cambogia extract and green tea extract were frequently used as health functional foods. One of 10 (10.3%) consumers of weight-control foods reported ≥ 7 months use, with less frequent long-term consumption of health functional foods (4.2%). The average degree of satisfaction was 3.24 ± 0.92 for weight-control foods and 2.72 ± 0.97 for health functional foods on a 5-point scale, meaning 'slightly satisfied' and 'slightly dissatisfied', respectively. Females or students with an experience of weight-control reported poorer perceptions of their health and body image as well as a higher need for weight control. Besides, both male and female subjects felt a high need for correct information regarding weight-control methods. Conclusions: Our results provide a better understanding of the characteristics associated with the use of weight-control or health functional foods among university students and will be useful in developing a nutrition education program by incorporating correct body image, knowledge, and practical yet desirable practices for weight control.

Purpose - We perform an empirical analysis of the effects of global consumer culture positioning (GCCP) in TV advertisements on consumer's brand evaluations (perceived quality, perceived price, and brand prestige) and attitude toward brand. Also, we analyze the moderating roles of consumer characteristics (ethnocentrism and level of product knowledge) in those effects. Design/methodology - This research is based on a survey of 210 randomly-selected university students in Seoul, Korea. The participants in the survey were shown a total of 8 TV advertisements of consumer goods of nondurable goods (fast food and carbonated drinks), and durable goods (sports shoes and digital camera), which included two advertisements for each product where one uses GCCP strategy while another uses LCCP strategy. We estimate the structural model using the AMOS 18.0 computer program. Findings - We find that GCCP has more positive effects on consumers' brand evaluations and attitude toward brand than LCCP in TV advertising. We also find that GCCP has stronger effects on brand evaluation and attitude toward brand in consumers with weak ethnocentrism and in those with a low level of product knowledge. Practical implications - Using GCCP in an advertisement is an effective way of improving consumer's evaluation of the brand and attitude toward the brand mainly when cosmopolitan consumers and consumers with low knowledge levels are segmented as targets. Originality/value - The study contributes to identify how and for what consumer groups' global brand positioning strategies in TV advertisements affect consumers' brand evaluations and their attitudes toward brands.

Purpose: It is important to consider both clinical factors and epidemiological factors in treating burn patients in emergency rooms. However, many emergency medical staffs happen to miss their chances of treating burns based on these considerations. This study is designed to find a better treatment for burn patients in emergency rooms along this approach. Methods: This study was conducted based on the data of the burn patients visiting the emergency room of a single general hospital from January 2015 to December 2019. The epidemiological and clinical factors were extracted out of the data, then the relationship between the prognosis and these factors were analyzed. Results: Most of burn accidents occurred at home, and were caused by hot water, soup, drinks, oil, etc. Especially, flame burns showed high hospitalization rate, surgical rate and mortality. In addition, their prognosis was poor when the affected area included facial, limb and perineal areas etc., or any inhalation burn co-existed. Also, the hospitalization rate and period increased when the treatment time was delayed or the pre-treatment was taken. There was a strong relationship between prognosis and the period of follow-up when patients were admitted during the period. Conclusion: It is difficult for medical staffs to evaluate prognosis of burns in emergency rooms due to progressive damages. Precise treatment and disposition are essential for patients' good prognosis. Therefore, medical staffs should establish treatment plans by identifying the patient's epidemiological and clinical factors, rather than giving prescriptions based on fragmentary and superficial symptoms.

Background and Objectives: To investigate the relationship between hearing impairment and alcohol drinking patterns in South Korean adults. Subjects and Methods: Data collection was performed by Korean National Health and Nutrition Survey from January 1 to December 31, 2012. Data analyses were performed from February 20 to March 3, 2018. Data from 3,860 adults 20 years of age or older without a history of malignancy or chronic otitis media in the Korean National Health and Nutrition Survey 2012 database who participated in the health questionnaires, and who had available results from otologic examinations that included pure tone audiogram, were included. Pure-tone average hearing thresholds were calculated at 500, 1,000, 2,000, and 4,000 Hz. Hearing loss was defined as a pure-tone average >40 dB in one or both ears. The Alcohol Use Disorder Identification Test was used to evaluate drinking statuses of subjects. Data were analyzed using the complex-sample χ²-test of independence and a complex-sample logistic regression analysis. Results: Of the 29,954,319 individuals in the weighted cross-sectional study population, 15,106,040 (50.4%) were men and 14,848,098 (49.6%) were women. A total of 8.1% of men and 7% of women had hearing impairment. The degrees of drinking with appropriate, risky, and hazardous drinking habits were 58.2, 32.1, and 9.7% among men; and 76.4, 12.5, and 11.1% among women, respectively. Among men, the odds ratio of hearing loss increased by 2.506 times when comparing hazardous and appropriate drinking (confidence interval, 1.083 to 5.800, p=0.002). Moderate alcohol consumption (≤2 drinks per day) was not protective for hearing in either group. Conclusions: As hazardous drinking tends to coexist with hearing impairment in men, appropriate prevention and intervention strategies should be emphasized. A longitudinal study to investigate harmful drinking and the mechanism of hearing loss should be performed.

With the recent changes in society and the introduction of new technologies, the usage patterns of parks have become diverse, leading to increased complexity in park management. As a result, there is a growing demand for flexible and diverse park management that can adapt to these new requirements. However, there is inadequate discussion on these new demands and whether urban park management policies can respond. Therefore, empirical research on how park usage patterns are evolving is critical. To address this, blog data, in which individuals share their experiences, was used to examine the spatial consumption patterns through semantic network and topic analysis. This study also explored whether these spatial consumption patterns exhibit experiential consumption characteristics according to the experience economy theory. The results showed that consumption behaviors, such as renting picnic sets and having food and drinks delivered, were prominent and that emotional experiences were pursued. Furthermore, these findings were consistent with the experiential consumption characteristics of the experience economy theory. This suggests that park planning and maintenance methods need to become more flexible and diverse in response to the changing demands for park usage.

This study was performed to investigate the effect of the health related factors on the preference and frequency of intake of coffee and traditional beverages among 280 university students (128 males and 152 females) who were residing in Incheon areas. The results were as follows; 1. Male students of over weight and obese were more than female students and female students of under weight were more than male students. Female students were interested in weight control and had an experience in weight control more than male students. 2. The group who was much interested in weight control preferred green tea, yuja tea and dunggulre tea. The group who was much interested in health when drink beverages preferred green tea, ginseng tea, dunggulre tea, vinegar drinks and water but didn’t prefer coffee. 3. The frequency of intake of green tea is high in the group who had an experience in weight control. And the frequency of intake of honey tea was high in the group who drank alcohol almost every day. Coffee intake was the highest among beverages in smokers and water intake was the highest among beverages in nonsmokers. In conclusion this study showed that as an interest in health is higher, the preference and frequency of intake of coffee was low whereas those who intake of traditional beverages was high in general.

The purpose of this research was to investigate consumers' perceptions of foods that are most compatible with traditional Korean liquors. The study participants were a total of 402 customers who visited traditional Korean bars. Thirty-eight percent of the participants drank alcohol once or twice a week, and overall, 79% drank with friends or co-workers. Forty-three percent spent 30,000-40,000 won on alcoholic drinks, and half of them frequently drank distilled Soju whereas 27% drank beer. Those who drank traditional Korean liquor chose to do so because they viewed it as good for their health and the beverage was tasty. Participants selected Yakju/Baekseju (47.5%), Bokbunjaju (21.1%), and Takju/Makgeoli (8.2%) as the most compatible Korean traditional liquors with Korean traditional foods. The most compatible foods with Yakju were identified as Haemulpajeon (11.8%), Dubukimchi (9.8%), and Bossam/Suyuk/Pyeonyuk (7.5%). Bokbunjaju was viewed as a good match with Jangeogui (8.1%), Hunjeori (6.5%), and Saengseonhoe (6.4%). The respondents perceived Deodeokgui (6.7%), Saengseonhoe (5.9%), and Dubukimchi (5.6%) as the most compatible foods with Yakju with mushrooms. Chengju was viewed as a good pairing with Eomuktang (9.2%), Altang/Maeuntang (7.2%), and Saengseonhoe (6.8%). The respondents thought Takju went well with Haemulpajeon (17.7%), Dubukimchi (14.2%), and Kimchijeon (11.7%). And finally, Altang/Maeuntang (11.8%), Samgyeopsalgui (8.7%), and Honghaptang/Jogaetang (8.1%) were mentioned as the most compatible foods with distilled Soju.
