Objectives: The purpose of this study was to investigate the correlation between soft drink consumption and subjective oral symptoms in Korean adolescents. Methods: Data of 65,528 adolescents were derived from the twelfth Korea youth risk behavior web-based survey, which was conducted from 1st June 2016 to 30th June 2016. Sociodemographic factors, dietary habit, and oral health behavior were collected as independent variables. The subjective oral symptoms were used as a dependent variable. The chi-square test and logistic regression analysis were performed to identify the correlation between dental caries and the other variables. Results: A multiple logistic regression analysis revealed that subjective oral symptoms were correlated with sex, age, subjective economic status, soft drink consumption, sweet drink consumption, tooth brushing frequency and dental sealant experience. Conclusions: Since the intake of soft drink adversely effects subjectively perceived oral symptoms in Korean adolescents, oral health education should include information on the pH levels of food and beverages including carbonated drinks, the effects of sugar on the teeth, and precautions to preventing tooth damage.

This study assessed the association between vitamin D sufficiency (serum 25(OH)D ${\geq}30ng/mL$) and alcohol consumption using data from the Korea National Health and Nutrition Examination Survey conducted in 2009. The following characteristics were obtained in 7,010 Korean participants ${\geq}19$-years-of-age: serum 25(OH)D level, alcohol consumption (drinking frequency, drinking number of alcoholic beverages on a typical occasion, average daily-alcohol intake), and potential confounders (age, residence, housing status, occupation, total fat and lean mass, smoking, physical activity, history of liver diseases, liver function, and daily intake of energy, protein, and calcium). After adjusting for confounders, vitamin D sufficiency in men was significantly associated with drinking frequency, number of alcoholic drinks consumed, and average daily alcohol intake; odds ratio of 1.21-1.72, 2.17-3.04, and 2.27-3.09, respectively. Increase in the three alcohol drinking-related behaviors was also linearly associated with increase in serum 25(OH)D level in men. By comparison, there was no significant association between alcohol intake and serum 25(OH)D level in women. The positive association between vitamin D sufficiency and alcohol consumption was evident only in Korean men.

Despite provision of drinking water as the most common method of occupational heat stress prevention, there remains confusion in hydration messaging to workers. During work site interactions in a hot and humid climate, workers commonly report being informed to consume tepid fluids to accelerate rehydration. When questioned on the evidence supporting such advice, workers typically cite that fluid absorption is delayed by ingestion of chilled beverages. Presumably, delayed absorption would be a product of fluid delivery from the gut to the intestines, otherwise known as gastric emptying. Regulation of gastric emptying is multifactorial, with gastric volume and beverage energy density the primary factors. If gastric emptying is temperature dependent, the impact of cooling is modest in both magnitude and duration (${\leq}5$ minutes) due to the warming of fluids upon ingestion, particularly where workers have elevated core temperature. Given that chilled beverages are most preferred by workers, and result in greater consumption than warm fluids during and following physical activity, the resultant increased consumption of chilled fluids would promote gastric emptying through superior gastric volume. Hence, advising workers to avoid cool/cold fluids during rehydration appears to be a misinterpretation of the research. More appropriate messaging to workers would include the thermal benefits of cool/cold fluid consumption in hot and humid conditions, thereby promoting autonomy to trial chilled beverages and determine personal preference. In doing so, temperature-based palatability would be maximized and increase the likelihood of workers maintaining or restoring hydration status during and after their work shift.

Purpose: The purpose of this study was to analyze the relationship between physical activity and energy drinks consumption in Korean Adolescents. Methods: This study was a secondary data analysis using statistics from the 2017(13th) Korea Youth Risk Behavior Web-based Survey. The variables used in the study were physical activity, energy drinks consumption and socio-demographic characteristics such as gender, academic achievement, household economic status and weekly allowance. The data were analyzed by $x^2$ test and multinominal logistic regression and the results were presented in percentage. Results: As the number of days engaging in moderate and vigorous physical activities increased, the response that they consume energy drinks 'more than 5 times a week' also increased. The subjects who participated in a 'moderate' or 'high' level of moderate physical activity consumed 1.4 times more energy drinks than those who do not participate in physical activity. And the subjects who engaged in a 'low' or 'moderate' level of vigorous physical activity consumed about 1.3 times more energy drinks than those who don't work out. Conclusion: As the level and intensity of physical activity increased, the number and frequency of energy drinks consumption increased. The results of this study can be used as basic data for intervention programs to reduce energy drinks consumption and promote proper physical activity.

This study aimed to analyze preferences depending on consumption value in relation to fashion jewelry design, colors, and materials. For this, 156 female consumers participated in it as subjects, and for a research tool of consumption value, VALS (Values and Life Style) technique was employed to make an empirical analysis by dividing it into three types such as principle-oriented value, status-oriented value and behavior-oriented value. Research findings indicate that above all, there are differences in preferences depending on characteristics of fashion jewelry design depending on consumption value. It was found that there are differences in preferences depending on numbers of setting of fashion jewelry depending on consumption value, but it was found that there are no differences in preferences depending on jewelry materials. In addition, it was observed that for color characteristics of fashion jewelry, there are differences in preferences depending on consumption value. There are differences in preferences for fashion jewelry depending on consumption value, which indicates that preferences for products change depending on consumers' consumption value rather than use value. And it can be an explanation for this reason. Therefore, it is necessary to work out a more efficient strategy through a process of setting up a target according to consumption value.
