This study investigates drinking attitudes and behaviors of university students. The sample included 355 students living in Busan, Korea. The questionnaire addressed general background information (gender, age, grade and monthly pocket money), drinking attitudes (understanding the effects of alcohol on the body, stereotype of drink, age at the first drink, the drinking companion at the first drink, reasons for starting to drink, main drinking companions, major reasons for drinking, the history of drinking alone, and reasons for drinking alone), drinking behaviors (the cost of each drinking occasion, drinking amounts, the frequency of drinking, the frequency of heavy drinking, the type of alcoholic beverage, and the places of drinking). A few respondents (both male and female students) started drinking while in high school (p<0.05), and most respondents drank with friends (males: 91.0%, female: 92.2%). The main reasons for drinking were the mood for male student (46.3%) and relationships for female student (49.1%) (p<0.05). Male respondents consumed more than seven glasses of soju (39.9%), whereas female respondents, five to seven glasses (49.7%) (p<0.05). On average, the respondents drank one to two times a week (males: 47.9%, females: 51.5%) and experienced heavy drinking one to three times every three months (males: 19.1%, females: 21.0%) (p<.05). The results suggest that students with frequent alcohol consumption and heavy alcohol dependence are likely to face problems and thus require aggressive intervention strategies that target them specifically.

Alcohol is the most widely psychoactive drug and has known in almost all civilization since ancient time. Recently increase consuming alcoholic beverages, alcohol is on of the major public health problems in the world. Alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) play important roles in the metabolism of alcohols and aldehydes. The drink consists of medicinal herbs, Puerariae Radix, Phyllostachyos Folium, Citri Pericarpium, Polygonati Rhizoma, Rehmanniae Rhizoma (Vinegar), which have been widely used in oriental medicine. This study was designed to investigate effects of medicinal herbal drink (MHD) on alcohol metabolism in drunken SD rats subjects. In experiment, rats were treated to ethanol (EtOH, 3 g/kg, PO) at 60 min. after saline (CON) or MHD (1 ml/kg, PO) administration. The blood alcohol concentration (BAC), blood acetaldehyde concentration (BALC) activities of ADH, ALDH, AST and ALT were significantly decreased in MHD group than in control group as a time-dependent manner. And drinking water volume in MHD group with duplicate treatment, were significantly decreased than in CON group. These results suggested that MHD intake could give an influence upon the reduction in BAC and BALC may alleviate acute ethanol-induced hepatotoxicity by altering alcohol metabolic enzyme activities.

This study investigated the influences of the beverage intake on food behavior and personality for 1295 adolescents. The results were as follows. The favorite beverage was 'fruit juice', and preference of 'coffee' was the lowest. 'Milk and dairy product' was highest and 'milkshake' was lowest in intake frequency of beverage. The preference correlated positively(r = 0.391) with the intake frequency of beverage, especially high in 'green tea and black tea'(r = 0.622), 'coffee'(r = 0.581), 'carbonated drink'(r = 0.538), and 'milk and dairy product'(r = 0.501). The explanation power(R2) of beverage preference on beverage intake was 0.153. The explanation power($R^2$) of beverage intake on food behavior was 0.127, and 'carbonated drink' and 'coffee' as well as 'milkshake' had a negative influence on food behavior: however, 'milk and dairy product', 'green tea and black tea', and 'fruit juice' had a positive influence on food behavior. The relationship of beverage intake and sociality was very low($R^2$= 0.013), and 'isotonic drink' and 'green tea and black tea' had a positive influence on sociality. The relationship between beverage intake and anger expression was also very low. 'Coffee' showed a positive relationship with anger-in. 'Carbonated drink' and 'milkshake' showed a positive result with anger-out. 'Milkshake' showed a negative relation with anger-control, but 'green tea and black tea' and 'milk and dairy product' showed a positive relation. From these results, it was necessary to develop the practical nutritioneducation program on proper beverage choice for adolescents leading to better metal and physical status.

Through a survey on dietary intake of children and adolescents with brain lesions, the present study aimed to analyze the current status of nutrient intake and examine the effect of high-protein nutrient drink on their nutritional and muscle statuses. The study participants were 90 juvenile participants aged 8-19 years, with brain lesions. The participants were provided with a protein nutrient drink for 12 weeks and a questionnaire survey on dietary intake was performed to analyze the level of nutrient intake before and after ingestion. The physical measurements were taken to determine the improvements in nutrient and muscle statuses. The results showed that, before the intake of protein nutrient drink as a supplement, the participants exhibited lower height, weight, and body mass index than those of the standard levels of healthy individuals, and the level of nutrient intake through diet was lower than those of the required and recommended levels of nutrient intake for Koreans. Conversely, after the intake of protein nutrient drink for 12 weeks, the level of nutrient intake and physical statuses such as weight showed significant improvements. In addition, the muscle status had undergone approximately 10% of change during the intervention with no significant difference. Thus, to ensure an adequate level of nutrient supply to children and adolescents with brain lesions, there is an urgent need to develop a guideline of nutrient intake. The findings in this study are expected to serve as the basic data for such guidelines.

Nowadays drunken drive and other problems related to drinking have been increased in our society. Those problems, we believe, are just the outcomes of undesirable drinking life. To investigate the drinking life of youngsters aged between 20 and 30, 271 university students and workers in Chongju area were surveyed, focusing on attitude toward drinking, drinking behavior and drinking habits. The results are as follows: 1. Youngsters, regardless of their sex, have generous attitude toward drinking. 2. Youngsters usually drink to get along with their friends or fellow workers. 3. The university students drink alone more frequently than the workers do. And to drink alone occurs when they feel mental stress or face difficulties. 4. The university students and the workers do not differ in terms of average drinking frequency per month, the number of pubs they stop by per drinking occasion, and the king of liquor they take. 5. Above 80% of the car owners have experienced the drinking drive. And they tend to smoke more while drinking.
