Beverages using mountain edible herbs(MEH) were formulated by determining optimum ratio of juices of MEH to several other ingredients. Fermented beverages were made by mixing juices(1 volume) fermented with Lactobacillus helverticus with syrup(3 volumes), followed by homogenization and flavoring . The general analysis and quality change of the beverages during storage were Peformed. The analysis of the beverages showed that the pH of Synurus deltoides and Cirsium sctidens were 3.8 and 3.7, titratable acidities were 0.50 and 0.49, optical densities were 1.201 and 1.119, respectively, The pH and color were not significantly changed when Synurus deltoides and Cirsium sctidens were stored at room temperature and 37$^{\circ}C$ for 6 months. The pH of Synurs deltoides beverage ranged 3.95~3.96 and pH of Cirsium sctidens was 3.83~3.95 at room temperature and 3.87~3.98 at 37$^{\circ}C$, respectively. The analysis of fermented beverages showed that pHs of Synurus deltoides and Cirsium sctidens were 3.65 and 3.70, titratable acidities were 0.57 and 0.60. Solids-non-fat were 3.2 and 3.1, and total counts of lactic acid bacteria were 2.5$\times$10$^{8}$ and 4.0$\times$10$^{8}$ , respectively. The changes of pH and titratable acidities stored at 4$^{\circ}C$ for 15 days were 3.39~3.56 and 0.61~0.81 for Synurus deltoides and 3.48~3.67 and 0.60~0.78 for Cirsium sctidens, respectively.

Volatile profiles of beverages and encapsulated powders containing Artemisia princeps Pampan extracts were analyzed by solid-phase microextraction-gas chromatography/mass spectrometry during production and storage. Beverages containing 0.32 and 0.64% extracts were stored at room temperature for 8 weeks and $60^{\circ}C$ for 8 days, respectively. Encapsulated particles were stored at room temperature and $60^{\circ}C$ for 8 days. Total volatiles in beverages decreased significantly during storage, irrespective of storage condition (p<0.05). Terpenoids, including cymene, thujone, and ${\beta}$-myrcene, were major volatiles in beverages, and some volatiles including ethylfuran, vinylfuran, and 2-fufural increased in 60oC samples only. Total volatiles in microcapsules at room temperature were not significant different for 8 days (p>0.05), whereas those at $60^{\circ}C$ increased by 16.5 times. Limonene was the most detected volatile in microcapsules, and aldehydes such as hexanal, pentanal, and octanal, and furans such as 2-butylfuran and 2-pentylfuran increased in the $60^{\circ}C$ samples, which may have originated from oxidized lipids used in the microcapsules.

The consumption of beverages among children is rising. The purpose of this study was to examine the effect of kid's drink on dental resin-based pit and fissure sealant. Pororo, I-kicker, Sunkist kids were included in the experimental groups, and Samdasu was included in the control group. A conventional dental sealant material ($Clinpro^{TM}Sealant^{(R)}$) was selected for this study. Resin specimens (8 mm in diameter and 1 mm in thickness) were prepared according to manufacturers' instructions and the initial roughness (Ra) was then measured. The pH of all the four groups was measured using a pH meter. The specimens were individually immersed in 5 ml of the experimental solutions and stored at $37^{\circ}C$ for 72 hours. Following this, the surface roughness of the resin specimens was measured by Surftest. The concentration of residual monomer released was determined by high performance liquid chromatography (HPLC). The surface morphology of the resin specimen was evaluated before and after storage by scanning electron microscopy (SEM). Data were statistically analyzed using Kruskal-Wallis and Duncan's test. The results showed that all the children's beverages examined in this study contained citric acid. The pH of I-kicker was the lowest ($3.03{\pm}0.01$), followed by that of Sunkist kids ($3.26{\pm}0.02$) and Pororo ($3.47{\pm}0.02$). We observed an increase in the surface roughness of resin specimens after 72 h of immersion in all the beverages tested (p<0.05). There was matrix degradation after immersion, visualized on SEM image, in all the beverage groups. Bisphenol-A-glycidyl methacrylate was not detected after 72 hours, but triethylene glycol dimethacrylate levels were increased in all the beverages tested during the 72 hours by HPLC. These results suggest that intake of beverages containing acid can cause degradation of the resin-based pit and fissure sealants in children.

This study investigated the status of drinking highly caffeinated beverages by Korean adolescents, and we identified the factors influencing this behavior by Korean adolescents by using statistics from the 13th (2017) Survey on Youth Health Behavior Online Survey. The data was collected from 62,276 middle and high school students and the variables of this study included demographic factors, health behavioral factors, mental health factors and the availability of highly caffeinated beverages. The methods of data analysis included descriptive statistics, Chi-square tests and logistic regression analysis. This study found that the intake rate of highly caffeinated beverages was 1.9% for men and 1.5% for women, and these percentages increased with age (p<0.001). Current smoking and drinking, current drug usage and active people also had high intake of caffeinated beverages (p<0.001). A high level of stress, a low level of subjective sleep satisfaction and a feeling of happiness increased the rate of consuming highly caffeinated beverages. The factors of drinking highly caffeinated beverages were gender, age, smoking, physical activity, drug use, stress level, depression and suicidal ideation. Therefore, continuous discussion is needed to improve both the health behavior and mental health by managing the stress felt by Korean adolescents.

We measured the rate of water transfer across the isolated small intestine of the rat in Wiseman apparatus using tritiated water ($^3H_2O$) in drinking beverages such as electrolytes solution, fruit juice, carbonated water and barley water. Initial transfer rate of water using four beverages were determined: Electrolytes solution is the fastest and followed by barley water, carbonated water and fruit juice.

The purpose of this study is to analyze the foods which 424(male 171, female 253) university students surveyed consumed frequently and to evaluate and the factors affecting their food consumption patterns. The survey was conducted at the beginning of nutrition courses each semester, March and September, 1998, with the questionnaire composed of general information, food, drinking and smoking habits, nutrition knowledge/attitude and food frequency questionnaire. The rates of alcohol drinking in male and female students were 89.2% and 78.1% respectively, and the rates of smoking were 68.1% and 1.6% in males and female. The nutrition knowledge score was higher in females than in males, but the nutrition attitude score was not significantly different between the male and female groups. The foods frequently consumed among students were cooked rice(14.3/week), kimchi(11.1/week), coffee(5.7/week), vegetables in soup, jjigae and jorim(3.5/week), carbonated beverages(3.3/week), cooked mixed rice(3.2/week). Ramyun and chocolate·candies·biscuits were frequently consumed, too. There were several factors influencing food consumption patterns. These were gender, regularity of mealtimes, the status of alcohol drinking and smoking, residence type and the levels of nutrition knowledge and attitude. Males ate more frequently cooked rice, coffee, carbonated beverages, ramyun, functional beverages and ham·sausage, while females ate more frequently cooked mixed rice and fruits. Those who had the habits of irregular mealtimes seemed to eat more soft drinks, instant foods and snacks. These trends were also found in the alcohol drinking and smoking groups. High level groups for nutrition knowledge of attitude score chose raw yellow green and green vegetables, cooked mixed rice, soybeans and seaweeds more frequently than the other groups. On the other hand, low level groups for nutrition knowledge or attitude score were apt to eat carbonated beverages and ramyun more frequently. Therefore, more attention should be taken to males, having habits of irregular mealtimes, alcohol drinking and smoking, and low level groups for nutrition knowledge or attitude score so as to improve their health.
