We identified the intake pattern and consumption propensity of milk and sought improvements to promote consumption of milk. We targeted 362 preschool children aged 5~7 years old who attended nursery school in the Bucheon area. Questionnaires were distributed and 328 questionnaires were collected. Approximately 36.2% of boys and 31.2% of gorls drank milk six times per week. A total of 32.9% of the preschool children drank more than 2 cups of milk/day. Approximately 72.9% of them currently drink white milk, and 46.0% preferred milk to processed milk. The reasons why they drink milk included 'want to be tall'(66.5%) and 'good health'(52.4%). Mothers(54.6%)and preschool children(39.3%) were the purchasers with the greatest impact on product purchases. Consumer propensity to buy milk was shown in the order of expiration date(4.80 points), and nutrition facts(4.01 points). (4.88 points) and enhanced nutrients(4.59 points) should be promoted for milk consumption. Therefore, it is thought that continuous nutrition education should be made together in order to increase consumption of milk of children and education targeting teachers and school parents should be conducted as well. And in order for children to drink milk without repulsion, the development of various products satisfying both symbolic aspects and nutritional aspects should continue to be made.

This study was conducted to investigate the changes in alcohol consumption of male university students in Daegu, Korea and their drink-related behavior. The study focused on these changes over a decade using self-administered questionnaire surveys and health examinations that were carried out at a university campus in 1999 and in 2009. In both years more than 85% of students responded that they drank alcohol. However, significant increases in the frequency and amount of alcohol consumption were found (p<.001). The main influence on students' drinking behavior was friends/peers in both years. The most frequently preferred alcohol of respondents was so-ju (a traditional Korean liquor) in both years. However, the most frequently preferred type of food to accompany drinking had significantly changed (p<.01). Other changes including the increase of drinking speed and smoking during drinking were found to have significantly changed (p<.05) while significant difference regarding the decrease in food intake during drinking was not found. No significant difference in the amount of alcohol consumed was noted between underage drinkers and drinkers of above the legal drinking age. Heavy drinkers in the 2009 population had significantly higher systolic blood pressure than non-drinkers and moderate drinkers (p<.01). This study also indicates that there may be a rise in heavy drinking and/or binge drinking among drinkers including underage students. The results of this study suggest that alcohol-blood pressure associations are considered to be of concern even in young adults. This study also suggests the need for special alcohol prevention programs or campaigns to intervene in the behavior of students.

Purpose: The purpose of this study was to understand the impact of long- and short-term energy drinks on anxiety-like, depressionlike, and cognitive behavior in adolescent rats. Methods: Adolescent rats (age six weeks) were randomly classified into a control group (CON), a long-term administration group (LT), and a short-term administration group (ST). The LT group was orally administered 1.5 mL/100 g (body weight) of energy drink twice daily for 14 days, the ST group was orally administered for one day, and the control group applied the same amount of normal saline. Later, an open-field test, a forced swim test, novel object recognition test, and an 8-arm radial maze test was conducted to assess the rats' anxiety, depression, and cognitive function. Results: There were different effects in the long- and short-term groups of energy drink administration. In the LT group, anxiety- and depressive-like behavior increased because of increased movement in the side corner and decrease of immobility time. Also, the time to explore novel objects decreased, and the number of correct responses was reduced, indicating a learning and memory function disorder. However, the ST group was not different from the control group. Conclusion: These results indicate that long-term consumption of energy drinks can increase anxiety-like, depression-like behavior, and this can lead to decrease in learning and memory functions. Thus, nurse and health care providers should understand the impact of energy drink consumption in adolescence to provide appropriate practices and education.

BACKGROUND/OBJECTIVES: The objective of the study was to provide useful insights into plain water intake of Korean adults according to life style, anthropometric, and dietary characteristics. SUBJECTS/METHODS: The data from the 2008-2010 Korea National Health and Nutrition Examination Survey were used. The subjects were 14,428 aged 20-64 years. Water intake was estimated by asking the question "How much water do you usually consume per day?". Dietary intake was estimated by 24-hour dietary recall. A qualitative food frequency questionnaire including 63 food items was also administered. RESULTS: The mean plain water intake for men and women were 6.3 cup/day and 4.6 cup/day, respectively. Plain water intake increased as lean body mass, waist circumference, and body mass index levels increased, except for percentage of body fat. As energy and alcohol intakes increased, plain water intake increased. As total weight of food intake and total volume of food intake increased, plain water intake increased. Plain water intake increased as consumption of vegetables increased. Plain water intake increased as frequencies of green tea, alcoholic drink, and all beverages were increased in men. Plain water intake increased with increased frequencies of green tea, milk, soy milk, and alcoholic drink and decreased frequencies of coffee and soda in women. CONCLUSIONS: Our results suggest that persons who had a higher waist circumference or lean body mass and women with higher BMI consumed more plain water. The persons eating high quality diet, or the persons who had more vegetables, green tea, milk, soy milk, or alcoholic drink consumed more plain water.

According to "The Annals of the Joseon Dynasty", we know that korean ancestors confuse tea prescription with green tea. It makes cultural misunderstanding Tea doesn't mean green tea but tea prescription. It is caused that tea prescription has been called tea habitually in Korea. Korean don't drink green tea much. Instead, they have had a habit of drinking decoction of medicinal herbs and they called it tea. This habit has developed into Korean traditional tea culture. In the palace in the Joseon Dynasty period, Ginseng tea was used in the tea ceremony. When the king had poor health or had a disease or was even on the eve of death, a royal physician tried to cure him by tea. They used about 30 kinds of tea according to "The Annals of the Joseon Dynasty" Such as ginseng tea, astragalus tea, ginger tea. Tea in korea is not a drink but the way to cure a disease. Korean people usually get to drink decoction of other herbs instead of green tea. This became the basis of korean traditional tea culture. We need to change a definition of Korean tea like this way and study about it much more. With this research paper, korean tea culture should be studied on more various ways and established itself as original and unique tea culture. On the basis of this studies, Korean tea brand can be famous in the world like Chinese tea or Japanese tea.

Alcohol consumption has numerous health consequences for the human body. For example, heavy drinking on a daily basis causes liver diseases, and certain products such as acetaldehyde produced from alcohol metabolism are more toxic than alcohol itself. Accordingly, the current study evaluated the role of Lactobacillus fermentum MG590 to enhance the removal of the toxic effect of alcohol in alcohol metabolism. The maximum activities of the alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) by L. fermentum MG590 were observed after 6 h of culture. The production of ADH and ALDH by L. fermentum MG590 was also confirmed by SDS-PAGE. Six hours after the addition of alcohol to a culture broth of L. fermentum MG590, the alcohol concentration decreased from 7.5 to 2.7％. From an in vitro evaluation based on hepatocytes, the viability of hepatocytes in a medium containing alcohol and the cytosol of L. fermentum MG590 was higher than that in a medium containing only alcohol. From an in vivo test using SD rats fed a 22％ alcoholic drink, the blood alcohol concentration (BAC), glutamic-oxaloacetic transaminase (GOT), and glutamic-pyruvic transaminase (GPT) in the rats fed a medium containing L. fermentum MG590 were lower than those in the rats fed a medium containing only the alcohol drink. These results demonstrate that the ADH and ALDH produced by L. fermentum MG590 play an important role in detoxicating alcohol in vivo. Therefore, a fermentation broth of L. fermentum MG590 could be used as an effective alcohol detoxification drink.

A total of 321 salaried employees were surveyed by questionnaires during September and October 2001 in order to investigate the bases for their choices between 26 popular menu items in JinJu restaurants. The subjects were aged 20 to 61 years, and were classified into 3 age groups (ages 20-29, 30-39, and over 40) and 2 gender groups. The data were analyzed using the SAS program for factor analysis. The results of this study were as follows: 1) The 26 popular menu items were classified into 6 factors by the 20-29 age group, into 5 factors by the 30-39 age group, and into 3 factors by the over 40 age group. The younger age group had the more numbers of factor which act as choice criteria of restaurant foods according to the purpose of eating out. 2) Because subjects classified steak and fast food into the same factor named 'new generation's food', we found that steak was an unfamiliar food for most of them, 3) The 20-29 age group had an aversion to Boshintang(dog soup), while the 30-39 age group and the over 40 age group liked Boshintang as a stamina food. 4) The over 40 age group, and men in all age groups, didn't choose Buffet and Shabushabu as a dinner food because they had negative attitudes toward novel or unfamiliar foods. 5) Women distinguished between a factor called 'social drink and party food' from a facor called 'dinner food', while men integrated the factor of 'dinner food' into the factor of 'social drink and party food' 6) Men preferred Samgyetang (chicken stew with ginseng) and Yangnyeumtongdak (spicy fried chicken) as a 'social drink and party food', while women preferred Dwaejibossam (boiled pork and kimchi) and Beef Bulgogi. In conclusion, most of subjects did not recognize fast food and steak as a meal, which were introduced recently in JinJu. The choice criteria and preferences of restaurant foods were different from the age and gender groups. The over 40 age group, and men in all age groups, had more negative attitudes toward novel or unfamiliar foods than the younger age and women groups.(Korean J. Nutrition 35(9) : 996~1006, 2002)

Sugars in Korean jujube fruit and jujube fruit drinks were studied. The sugars in Korean jujube fruit were extracted by boiling with water for 30min and stirring for 1 hour at 7$0^{\circ}C$ after soaking in the water for 24 hours at 4$^{\circ}C$ followed by crushing. Korean jujube fruit was found to contain 25% of sucrose, 21.2% of fructose and 20.7% of glucose. Korean jujube fruit drinks of V company and H company were found sugar composition of 5.9% and 6.9% of sucrose, 2.2% and 2.1% of fructose and 2.4% and 2.4% of glucose, respectively. No other mono- and oligosaccharides were detected in the test of TLC and HPLC. A viscous material in jujube fruit and jujube fruit drinks was separated by ethanol fractionation, and identified as pectin by 1H-NMR and carbazole analysis. Pectin of Korean jujube fruit, jujube drink of V company and jujube drink of H company was found to contain 61, 58 and 55% of galacturonic acid, respectively.

Onions are considered to be a promising source of the alcoholic drink because they are rich in sugar, amino acids and various nutrients. To isolate strains of Saccharomyces cerevisiae producing ethanol of higher concentration, 19 strains were subjected to screening. Among them, the strain producing the highest concentration of ethanol was OJ-8 strain. Onion's oder was effectively removed by treatment for 30 min with 10% (w/v) charcoal against medium and then heat treatment of onion extract for 40 min at $100^{\circ}C$. The optimum conditions for alcoholic fermentation was investigated in medium containing the onion extract. The optimal conditions for ethanol production was obtained by standing culture for 5 days at $25^{\circ}C$ with 5% inoculum volume.
