This study was conducted to examine the volatile flavor compounds of Hahyangju, a traditional Korean liquor, and to evaluate the effect of the beverage on alcohol metabolism in rats. By GC/MS analysis, 17 volatile flavor compounds including iso-butyl alcohol and iso-amyl alcohol were detected in Hahyangju. The concentrations of acetaldehyde and ethylacetate in Hahyangju were decreased by filtration. Alcohol (0.035 mg/dL) and acetaldehyde (0.29 mg/dL) levels in the blood of rats given Hahyangju (HT animals) were lower than in rats given 17% (v/v) alcohol (AT rats). Also, alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activities in HT rats were $24.63{\pm}1.8{\mu}$moles/mg protein and $9.8{\pm}1.3{\mu}$moles/mg protein, respectively, and were higher than in AT animals. The increases in ADH and ALDH activity in HT animals resulted in decreases in alcohol and acetaldehyde concentrations in blood, compared to the levels seen in rats given 17% (v/v) alcohol. These results suggest that Hahyangju may increase alcohol metabolizing activity, and consumption of Hahyangju may result in less of a hangover than follows ingestion of beverages (such as wine) containing about 17% (v/v) alcohol.

Characteristic chemical compositions of jujube wine using different preparation methods including fermentation were investigated. Fermentation for jujube wine started using whole fruit (JW1), seed-removed fruit (JW2) and whole fruit heated at $100^{\circ}C$ for 2 h and then extracted (JW3). The free amino acids and flavors were analyzed quantitatively by HPLC and GC-MS. A total of 18 amino acids were identified in all samples. The amount of total free amino acids was detected from 141-210 ppm (JW1), 147-342 ppm (JW2), and 336-362 ppm (JW3). Large amounts of proline, aspartate, glutamate, arginine and alanine were detected in jujube wine. Thirteen kinds of volatile compounds including six alcoholic compounds (ethyl alcohol, iso-butyl alcohol, n-butyl alcohol, iso-amyl alcohol, n-amyl alcohol, and phenethyl alcohol), four ester (ethyl acetate, hexyl acetate, ethyl caprylate, and phenethyl acetate) and three aldehydes (diethylacetal, furfural, and benzaldehyde) were detected. Ethyl alcohol (30.50-33.95% peak area), benzaldehyde (2.55-15.97% ratio), furfural (0.07-15.28% ratio), iso-amyl alcohol (1.04-14.73% ratio), and phenethyl acetal (0.78-9.28% ratio) were abundant in jujube wine.

Objectives : To investigate the prevalence of hazardous and harmful alcohol use, which are a subthreshold of alcohol related disorders, Methods : Direct-interview questionnaires to 1,183 rural persons (489 male, 694 female) were conducted in Chungju-city from July 2 to 20, 1998. As a screening instrument, the alcohol use disorders identification test (AUDIT) was used. Results : The prevalence of alcohol use was 41.7%. In males, it was 66.3% and in females, it was 24.4%. The mean of the AUDIT score of males and females was 13.2 and 5.6, respectively. As WHO guideline, the prevalence of hazardous alcohol use in males and females was 80.3% and 20.7%, respectively. This suggests that the prevalence of 'hazardous drinking' and 'harmful drinking' was 45.4% and 29.3% for males and 1.2% and 2.4% for females, respectively. Conclusions : This study presented the prevalence of hazardous and harmful drinking of a rural population in Korea and reviewed those health problems. Further evaluation to detect and treat lower alcoholic drinkers is recommended.

This is an exploratory study to describe drinking patterns and alcohol-related problems (ARP) in women. A probability sample was drawn from Kyungnam Providence area 20 to 59 age by a multi- stage cluster sampling method and secondary data analysis was used. Drinking patterns in this study involve lifetime prevalence of alcohol use, year prevalence, month prevalence , frequency and usual quantity of drinking alcohol in a situation, ARPs were measured by employing a modified version of ARP developed by Alcohol Research Group in U.S.A. Three measurements were constructed to represent alcohol-related problems by summing up 41 alcoholic statements, which were consequence, social consequence and dependence. The results were as follows; 1) The lifetime prevalence of alcohol use in women was $80.3\%$ and year prevalence $78.3\%$. High prevalence rates of drinking were observed in the twenties who have at least community college diploma. and frequencies of alcohol use were increased as age increased. 2) More than $27.3\%$ of the respondents who were reported to experience at least a ARP in a year. 3) ARPs were associated with age, religion, frequency and usual quantity of drinking alcohol in situation. Issues were proposed with respect to research methodology and policy implications for public health.

This study was undertaken to investigate the effect of increase in the ratio of zinc to copper and alcohol consumption on serum lipid content in Sprague-Dawley male rats during five weeks. Sixty rats were divided into six groups, CZ < zinc 30ppm diet >, CZA < zinc 30 ppm diet plus alcohol 5% solution >, HZ < zinc 300ppm diet >, HZA < zinc 300ppm diet plus alcohol 5% solution >, SHZ < zinc 600ppm diet >, SHZA < zinc 600 ppm diet plus alcohol 5% solution >. High ratio of zinc to copper groups < HZ, SHZ > were significantly decreased in high-density lipoprotein (p<0.01) and increased in total cholesterol, triglyceride, total lipid in serum(p<0.001, p<0.001, p<0.01). Triglyceride levels of serum in alcohol groups < CZA, HZA, SHZA > were significantly higher (p<0.001) than non-alcohol group < CCZ, HZ, SHZ >. Copper levels of serum were reduced in group high ratio of zinc to copper. These results present that high ratio of zinc to copper increase cholesterol(p<0.001) and alcohol consumption increase triglyceride(p<0.001) in serum. This close association to lipid metabolism in rats draw attention to the potential significance of zinc and alcohol nutriture in relation to cardiovascular disease.

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.

An appropriate parent role model for alcohol, tobacco and other drug abuse prevention in adolescence was designed as part of a comprehensive effort to reduce the use of alcohol, tobacco and other drugs by underage youth. The content of the model offers a new and positive chemical health model. The model calls for development of a set of guidelines that can provide the framework for examining alcohol, tobacco and other drug use. The actions of adults in the community, especially parents, are very important factors in whether or not youth use chemicals. So these guidelines can be used to assist parents and other adults with questions such as, what can we say to young people about using alcohol, tobacco or other drugs except that it's against the law? At what age and times are discussions appropriate? What can we do to make our community a healthier place in which young people can make better decisions about alcohol, tobacco and other drug use? The model acknowledges and affirms the legal and appropriate use of alcohol and other drugs as well as supports the decision not to drink. It encourages participants to consider their own guidelines for using and not using alcohol and other drugs. The guidelines can also be used as the basis for early intervention when use is illegal, unhealthy or risky. It is important to note that the model affirms healthy and appropriate use as well as nonuse.

Alcohol consumption among soldiers impairs health status, performance, and increases the risks of injuries and violence. This study examined drinking behaviors, health problems, and violence among enlisted soldiers at Adisorn military unit in Saraburi, Thailand. Data collection using self-reported questionnaires were distributed to 256 enlisted male soldiers in May 2017. Participants were age 20-22 (93%), Buddhists (98%), high school education or lower (93%). They purchased alcohol at their own expense (46.5%). For alcohol consumption, all were lifetime drinkers (100%). The current drinking patterns were different 28.5% were current drinkers, 65.5% are currently abstaining from drinking (64.5%), and 6.6% stopped drinking permanently. The top three alcohol beverages were beer (52.3%), brandy (25.0%), and hard liquor (19.5%). Problems related to alcohol were from lost balance/falls (6.7%), illness (10.2%), driving under the influence (19.5%), and accidents (24.2%). Violence from drinking in the past month was from fighting (28.1%). This study is the first to provide information about alcohol-related problems in enlisted male soldiers. There is the need to offer straightforward advice, brief counseling, and refer soldiers to receive treatment to prevent alcohol-related problems. Online social media and web-based programs were recommended as platforms to provide preventive alcohol message to the enlisted.

Aqueous mixtures of hyaluronic acid and poly(vinyl alcohol) system and hydrogels thereof were introduced to obtain new bioartificial materials that have excellent mechanical properties, biocompatibility and enhanced rheological properties. The interactions between hyaluronic acid and poly(vinyl alcohol) and/or borax were investigated by rheological measurements. Preparation parameters of the aqueous mixtures were mixture composition, the degree of hydrolysis of poly(vinyl alcohol) and borax concentration. From the rheological behavior, it could be deduced that the key factor of the interaction between hyaluronic acid and poly(vinyl alcohol) was the hydrogen bonding between them and the effect was pronounced with borax. Enhanced viscosity was observed at the composition of $20wt\%$ of hyaluronic acid solution and $80wt\%$ of poly(vinyl alcohol) and borax solution. Rheological properties were influenced by the degree of hydrolysis of poly(vinyl alcohol) and borax concentration. As the degree of hydrolysis and borax concentration increased, rheological properties increased due to the increased hydrogen bonding and networking of hyaluronate aggregates. Physical hydrogels from hyaluronic acid and poly(vinyl alcohol) were prepared and the composition dependence of the gels was rheologically investigated as well.
