Purpose: The purpose of this study was to assess alcohol and caffeine intake and identify the impact of alcohol and caffeine intake on body mass index, alcohol use disorder, and quality of sleep among university students. Methods: This study design was accomplished with a cross sectional survey and conducted from May to June 2014. One hundred and twenty-four freshmen of E university in S city, Korea were selected and evaluated by self-administered questionnaires. Alcohol and caffeine intake were measured by self-reported recall. The data were analyzed using descriptive analysis, independent t-test, one-way ANOVA, Pearson's correlation, and multiple linear regression. Results: The average amount of alcohol intake was $175.02{\pm}219.97g$ and the proportion of freshmen who took in more than 40 g per day of alcohol was 75%. The average amount of caffeine intake was $116.79{\pm}111.14mg$. Factors influencing alcohol use disorder were dwelling type (t=2.25, p=.027) and alcohol intake (t=8.11, p<.001). And, the factor influencing quality of sleep was caffeine intake (t=3.88, p<.001). Conclusion: In order to reduce the harmful drinking of university students, preventive activities for freshmen are required and efforts on the part of the school needed.

The variations of asparagine and aspartic acid contents among the soybean varieties and in the different parts of soybean sprout after the different durations of storage were investigated. Asparagine and aspartic acid are known to have the detoxifying effects on acetaldehyde, which is highly toxic metabolites in the process of alcohol metabolism in the human body. The contents of asparagine and aspartic acid of beansprout showed continuosuly increasing trends along with the days to cultivation with a great varietal difference, especially in the roots. The duration of seed storage did not affect contents of asparagine content; the longer storage decreased aspartic acid content remarkably.

Alcohol, which can easily be obtained in the same way as ordinary beverages, is harmful enough to cause death due to excessive drinking and chronic alcohol intake, so it is important to maintain a proper amount of drinking and healthy drinking habits. In addition, the incidence of behavioral disturbances and impaired judgments that can be caused by chronic alcohol drinking of more than adequate amounts of alcohol is also significant. Accordingly it is very useful for forensic science to check whether the person involved is drunken or is alcoholism state in various accidents. Currently, in Korea, alcohol consumption is determined by detecting the level of alcohol or alcohol metabolism 'ethyl glucuronide (EtG)' in blood or urine samples. However, analysis of alcohol or EtG in blood or urine can only provide information about the current state of alcohol consumption because of a narrow window of detection time. Therefore, it is important to analyze the EtG as a long-term direct alcohol metabolite bio-marker in human hair and to investigate relationship between alcohol consumption and EtG concentration for the evaluation of chronic ethanol consumption. In this study, we established an analytical method for the detection of EtG in Korean hair efficiently and validated selectivity, linearity, limits of detection (LOD), limits of quantification (LOQ), matrix effect, recovery, process efficiency, accuracy and precision using liquid chromatography tandem mass spectrometry (LC-MS/MS). In addition, the assay performance was evaluated in Korean social drinker's hair and the postmortem hair of a chronic alcoholism. The results of this study can be useful in monitoring the alcohol abuse of Korean in clinical cases and legal procedures related to custody and provide a useful tool to evaluate postmortem diagnosis of alcoholic ketoacidosis in forensics.

Over-consumption of alcohol leads to many side-effects such as malnutrition, liver disease, and neuronal disorders and many investigators have tired to identify methods for preventing the side-effects of drinking. In this study, we demonstrated the protective effect of a new food component, SAC-1, containing Hovenia dulcis Thumb and Lonicera caerulea Thumb extract against the side-effects of drinking. We observed that blood alcohol concentration, glutamic oxaloacetate transaminase, lipid peroxidation, and total glutathione level decreased significantly in plasma and liver of mice fed the SAC-1 extract before alcohol intoxication. In particular, SAC-1 had more of a protective effect than that of Hovenia dulcis Thumb extract alone. These results suggest that SAC-1 should further be developed to treat alcohol detoxification and stimulate antioxidative potentials.

Purpose: This study was aimed to investigate effects of breath alcohol concentration (BrAC) increase on visual field and readable visual field. Methods: 23 males in 20s (average age $21.17{\pm}2.19years$, body mass index (BMI) $22.09{\pm}2.16$) were selected and administered the amount of alcohol to reach 0.05% and 0.08% BrAC calculated by BAC (blood alcohol concentration) Dosing Software program. Then, visual field and readable visual field test with Vision Disk were conducted. Results: Visual field are measured as $74.41{\pm}15.97^{\circ}$, $64.98{\pm}17.93^{\circ}$, and $58.33{\pm}19.01^{\circ}$ (p=0.000) and readable visual field as $21.93{\pm}12.71^{\circ}$, $17.41{\pm}11.36^{\circ}$, $14.26{\pm}9.93^{\circ}$ (p=0.006) in 0.00%, 0.05% and 0.08% BrAC respectively. As breath alcohol concentration increased, both visual field and readable visual field decreased. Conclusions: BrAC increase with drinking could be the cause of safety accident by decreasing visual field and readable visual field, it is necessary to raise awareness.

The current study was carried out to investigate the effect of oral administration for 30 days of the Jijang kimchi extracts on prevention of diabetes, alcoholic liver injury and reduction of blood lipids in laboratory rats with alcoholic liver injury and diabetes induced by streptozotocin. In a diabetic model animals, the blood lipid profile, ALT, and AST levels were lower in kimchi extract groups compared to DC (diabetes control) group, and blood glucose level of DCJK (DC+oral administration with Jijang kimchi extracts) group was lower than that of DCCK (DC+oral administration with commercial kimchi extracts) group. Insulin levels were increased in order of NC (normal control), DCJK > DCCK > DC groups. In alcoholic liver injury model animals, ALT, AST and bilirubin were lowed in order of AC (alcohol group received 1 bottle of soju) > ACCK (1 bottle of soju plus oral administration with commercial kimchi extracts) ACJK (AC plus oral administration with Jijang kimchi extracts) > NC groups. In the clinical pathologic findings of liver tissue, AC group was severely injured, and tended to be improved in groups eating a 1 bottle of soju plus oral administration with kimchi extracts, especially Jijang kimchi extract group. The results suggest that eating Jijang kimchi can improve insulin secretion ability while lowering blood lipid profile, blood sugar and ALT, AST, and bilirubin levles in diabetic and alcoholic liver injury model animals.

This study was designed to investigate whether consumption of onion wine can reduce serum biomarkers of ethanol-induced fatty liver in rats. Male Sprague-Dawley rats were initially trained for meal feeding to prevent reduction of food intake. After the training period, rats were weight-matched and assigned to the following three groups: 1) a control group fed a control liquid diet containing maltose-dextrin, 2) an ethanol group fed an ethanol liquid diet with 95% ethanol, and 3) an onion wine group fed the same ethanol liquid diet but containing onion wine extract at 1 mL/d/group. All three groups were fed daily for 6 weeks. At 0, 3, and 6 weeks, blood was collected via the orbital sinus following overnight food deprivation and terminally organs collected. Blood lipids and transaminase activities significantly increased in the ethanol-fed group but significantly reversed in the onion wine-fed group. The hepatic levels of fat and cholesterol at 6 weeks were significantly elevated by ethanol administration but significantly reduced by onion wine. These findings indicate that onion wine may ameliorate ethanol-induced fatty liver by lowering hepatic and blood lipid levels.

It has been estimated that up to $80\%$ of all marine accidents have human elements as a cause. t of these, human elements of crew fatigue is main causes of marine accident. Crew fatigue involves sleep, schedule. workload. off-time. alcohol health and stress. With a ship handling simulator, the effect of alcohol on ship operational performance is studied for each 0.05 and $0.08g\%$ blood alcohol concentrations. A main effect for alcohol was found indicating that ship operational performance was significantly impaired by this alcohol relative to performance in the non-alcohol condition. The results of this research can be applied to minimize marine accidents as basic data.

The effect of different ethanol feeding protocols on the oxidative stress in liver and blain of rats was studied. The rats were fed 5%-ethanol solution in drinking water (5%-EtOH group) or 2.5g ethanol/kg body wt. once daily intragastrically (2.5g-EtOH group). The levels of thiobarbituric acid reactive substances (TRARS) and vitamin EI in the liver, cerebrum and cerebellum were measured. In the liver of 5%-EtOH group, the level of TBARS was not changed, whereas vitamin I was significantly increased compared to control group. In the liver of 2.5g-EtOH group, the level of TBARS was significantly increased compared to control group and the vitamin E concentration was not affected. The levels of TBARS were increased and the vitamin E concentrations were decreased significantly both in the cerebrum and cerebellum in 5%-EtOH group as well as in 2.5g-EtOH group. These results show that lipid peroxidation and vitamin E concentration in liver were varied according to the conditions of ethanol treatment, however, the vitamin E contents in cerebrum and cerebellum were affected by both ethanol intoxications used in this study.
