This study investigated intake of energy drinks, side effects and willingness to stop intake of 255 high school students in Gyeoungbuk region. The data were collected by the self-administered questionnaire. Frequency, t test, one-way ANOVA, Duncan's multiple range test, and ${\chi}^2$ test were conducted by SPSS Window V.21.0. About 78% of the respondents had experience of intake of energy drinks. The respondents were aware of energy drinks from 'advertisements on mass media (44.3%)', 'friends (32.2%)', and 'looking in stores (16.9%)'. The mean of the amount of energy drink intake per day was 30.62 mg. Forty-four percent of the respondents had energy drinks during an examination period, and 37% took it at home. The main reasons for intake of energy drinks were 'to fight off sleepiness', 'to recover from fatigue', and 'good taste' in order. Many respondents answered that energy drinks did not much help to increase concentration or learning ability. About 72% of the respondents experienced 'not feel sleepy' after having energy drinks. Half of the respondents experienced side effects such as palpitation, insomnia, and increase of urination. Most respondents had willingness to stop having energy drinks if it had bad effect on health.

A quantitative risk assessment tool was used to provide estimates of the probability that foot-and-mouth (FMD) virus-contaminated, smuggled animal products are fed to susceptible swine in Korea. Sensitivity analyses were conducted to attempt to distinguish between parameter uncertainty and variability, using different assumptions on the effect of cooking at home, the effect of the fresh meat, and the effect of heat treatment at garbage processing facility. The median risk estimate was about 20.1% with a mean value of 27.4%. In a scenario regarding all beef and pork were considered as fresh meat the estimated median risk was 3.4%. The risk was greatly dependent on the survival parameters of the FMD virus during the cooking or heat treatment at garbage processing facility. Uncertainty about the proportion of garbage that is likely contaminated with FMD had a major positive influence on the risk, whereas conversion rate representing the size of a load had a major negative effect. This model was very useful in assessing the risk explored. However, the model also requires enhancements, such as the availability of more accurate data to verify the various assumptions considered such as FMD prevalence in a specific country, proportion of garbage which is recycled as feed, proportion of food discarded as garbage. Other factors including the effect of selection of animals for slaughter, ante- and post-mortem inspection, the domestic distribution of the smuggled products, and susceptible animals other than pigs, are need to be taken into account in the future model development.

Background: Abnormal activation of matrix metalloproteinases (MMPs) plays an important role in UV-induced wrinkle formation, which is a major dermatological problem. This formation occurs due to the degeneration of the extracellular matrix (ECM). In this study, we investigated the cutaneous photoprotective effects of Ultraflo L treated ginseng leaf (UTGL) in hairless mice. Methods: SKH-1 hairless mice (6 weeks of age) were randomly divided into four groups (8 mice/group). UTGL formulation was applied topically to the skin of the mice for 10 weeks. The normal control group received nonvehicle and was not irradiated with UVB. The UV control (UVB) group received nonvehicle and was exposed to gradient-UVB irradiation. The groups (GA) receiving topical application of UTGL formulation were subjected to gradient-UVB irradiation on $0.5mg/cm^2$ [GA-low (GA-L)] and $1.0mg/cm^2$ [(GA-high (GA-H)] of dorsal skin area, respectively. Results: We found that topical treatment with UTGL attenuated UVB-induced epidermal thickness and impairment of skin barrier function. Additionally, UTGL suppressed the expression of MMP-2, -3, and -13 induced by UVB irradiation. Our results show that topical application of UTGL protects the skin against UVB-induced damage in hairless mice and suggest that UTGL can act as a potential agent for preventing and/or treating UVB-induced photoaging. Conclusion: UTGL possesses sunscreen properties and may exhibit photochemoprotective activities inside the skin of mice. Therefore, UTGL could be used as a potential therapeutic agent to protect the skin against UVB-induced photoaging.

Body mass index(BMI) is recognized as one of the most useful indexes for adiposity in children and adults. This study was conducted to provide information on BMI distribution by age and sex in Korean children, and to identify sociodemographic factors that affected BMI among children. The study was conducted on 2376 children(boys 1184, girls 1192) living in a middle-size city in Korea. Subjects were selected from the primary schoolchildren in grades 1-6 using the two-stage sampling method. Their mean age was 9.4 years. The percentile of BMI tended to increase as age increased in both sexes. The 85th percentile for boys, aged 6-12 years, was 19.8kg/㎡, and the 95th percentile was 22.5kg/㎡. The 85th percentile for girls, aged 6-12 years, was 18.9kg/㎡, and the 95th percentile was 21.5kg/㎡. Multiple regression analysis was carried out to predict BMI from percent ideal body weight (PIBW), age and sex. After adjusting PIBW and age, BMI for boys was 0.062kg/㎡ lower than that for girls. One year of age increased BIM by 0.55kg/㎡. The prevalence rate of overweight and obesity based on PIBW was 15.8% and 15.0% for boys, and 14.0% and 11.0% for girls, respectively. Demographic factors such as sex, age, and parents' obesity influenced children's BMI. After adjusting for sex, age and parents' BMI, the presence of another children in family, and mother's employment status showed a strong effect on children's BMI. The results suggest an age-sex specific BMI distribution of Korean children. The present study also provides direct evidence of a correlation between early life environmental factors, such as presence of siblings or mother's employment, and BMI level in Korean children.

Although antioxidant activities of Korean traditional fermented foods were reported by many researchers, study on antioxidant activity of microorganism originated from Korean traditional fermented foods was little. Therefore, we improved condition for antioxidant production by a bacterium isolated from home-made Chungkookjang. We selected a bacterial strain, which showed the highest antioxidative activity, from Chungkookjang and then named GJ. The selected GJ strain was identified as Bacillus methylotrophicus by alignment data of 16S rRNA gene nucleotide sequences. Improved medium compositions for DPPH radical scavenging activity were 0.25% sucrose, 1% peptone, 0.01% $MgSO_4{\cdot}7H_2O$ and initial pH 6.5, respectively. Optimal culture conditions were $30^{\circ}C$, 200 rpm and 4% inoculum volume, respectively. In improved conditions, DPPH radical scavenging activity of GJ reached to 91% in a short time. The strain GJ also possessed ACE inhibition and other antioxidative activities; ACE inhibition activity (49.4%), ABTS radical scavenging activity (99.8%), metal chelating activity (67.9%), SOD-like activity (36.5%) and reducing power ($A_{700}$ = 5.982) were observed, respectively. Therefore, our results suggest that B. methylotrophicus GJ strain may be potential candidate for functional foods, cosmetic products for anti-aging and medicine for diseases caused by oxidative stress.

This study assessed the nutrient intake for Korean adolescents using the estimated usual intake. The usual intake of 1,763 adolescents aged 12-17 years old was estimated from one-day 24-hour recall data in the 2010-2012 Korean National Health and Nutrition Survey. The nutrient intakes of four groups according to sex (male and female) and age (12-14 and 15-17 years old) were then assessed in reference to the 2015 Dietary Reference Intakes for Koreans. For macronutrients, the proportions of subjects below and above the Acceptable Macronutrient Distribution Ranges (AMDR) were calculated. The Estimated Average Requirement (EAR) cut-point method was used to assess insufficient intakes of protein, vitamin C, thiamin, riboflavin, niacin, calcium, phosphorus, and iron; the full probability approach was used to assess the insufficient intake for iron among females. The proportions of subjects over the Tolerable Upper Intake Levels for vitamin C, niacin, calcium, phosphorus, and iron and the proportions over the Intake Goal for sodium were calculated to assess excessive intake. The proportions of subjects above AMDR for carbohydrates ranged from 22.5% to 38.0% by group. The proportions of subjects by group with insufficient intake for vitamin C, riboflavin, calcium, phosphorus, and iron ranged 29.1-39.7%, 22.5-34.3%, 73.1-89.3%, 14.3-43.6%, and 23.2-55.5%, respectively. The proportions of subjects by group with excessive intake for sodium ranged from 91.5% to 99.3%. The results of this study represent important basic information to establish nutritional standards for school lunches as well as to decide on relevant nutrition policies for adolescents.

The findings of this study could provide useful information for consumer education and consumer policy development regarding GM foods. The specific purposes of this study were: (1) to examine consumers' attitudes toward GM foods, (2) to analyze the effect of the perception of GM foods and demographic variables on consumers' attitudes toward GM foods, and (3) to analyze the effect of the perception of GM foods and demographic variables on consumers' willingness to purchase GM foods. The questionnaire used in the survey was constructed by the author, based on existing literature. The survey was conducted with 1,100 housewives, and 723 of the completed survey forms were used in the final analysis. Frequencies, percentages, means, standard deviation, t-tests, ANOVA, Duncan-test, Pearson's Correlation, factor analysis, and discriminant analysis were employed for data analysis methods. Major findings are: (1) Consumers' attitudes toward GM foods consist of three factors, that are, attitude regarding potential danger, attitude regarding the use of GM technique on plants, and attitude regarding the use of GM technique on animals. (2) Consumers with a higher level of education tend to perceive GM food as more dangerous, whereas consumers with a lower level of education tend to accept more the use of GM technique on plants. (3) Consumers who tend not to consider GM foods as dangerous, and those who acknowledged benefits in using GM technique on plants are more willing to buy GM foods.
