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.

This convergence study was conducted to compare difference of risk behaviors and injury incidence between younger(under 65 years) and elderly(over 65 years). For this analysis we used law data of nation-wide community health survey data during August to October 2010. Data of drink-driving, seat belt use, injury incidence rate, type of injury, cause of injury were used for comparison. Seat belt use(85.16% vs 78.81%) was high but drink-driving(12.99% vs 13.24%) was low in elderly. Injury incidence was high especially in falls(1.07% vs 2.22%). In conclusion, elderly do less risk behaviors, but experienced much more injuries especially falls.

The purpose of this study was to examine how socio-demographic characteristics and delinquent behaviors affect the suicidal ideation among the Korean high school students. Using the 35,668 senior high school student cases of 2009 Korean Youth Health Risk Behavior On-line Survey data, it conducted a secondary data analysis. Frequency analysis, chi-square test and logistic regression analysis was done. Being female, living without parents, low economic status, poor academic record, technical school students, young students, poor academic record, internet addition, problem drinking, smoking cigarettes and experience of drug use significantly increased probability of their suicidal thoughts. Findings may be used for tackle the issues of suicidal thoughts among the Korean senior high school students.

This study intends to investigate the health behavior, self-efficacy, behavior pattern and social support among hospital of nurses, to provide the basic data for self-efficacy promoting program and social support promoting program. The self-administered questionnaires were given to 202 nurses employed in hospital during the period from June 10 to June 26, 2011. As a results, the score of level of self-efficacy was statistically significant difference according to educational status, working period, marital state, place of duty, religion, night-duty, distribution of household labor, exercise and stress management. The score of level of social support was statistically significant difference according to place of duty, religion and distribution of household labor, alcohol drinking, smoking, and stress management. But the score of level of behavior pattern was not statistically significant difference according to self-efficacy and social support. In correlation, the score of self-efficacy level correlated positively with social support and not with behavior pattern.

This study aims at investigate dietary behaviors, smoking and drinking status of university students depending on their gender and residential patterns, and analyzing relationships with their subjective health status. The subjects of this study was 538 university students in Metropolitan areas from May 10-31, 2010. Data were analyzed with chi-square test, fisher's exact test, t-test and stepwise multiple regression SPSS 12.0. Male students higher frequency on the intake of eggs, meats and carbonated drinks than female students. The group residing at one's own house showed higher frequency on the intake of beans, fruits and milk than the self-boarding group or other groups(p<0.05), while preferring sweet taste the most. Male students were significantly higher than female students in the amount of smoking and drinking(p<0.05). They had positive recognition on their health conditions as they have higher frequency on the intake of potatoes, seaweeds, green tea and milk with less frequency on the intake of eggs, fast foods and drinking amount. Accordingly, it was considered necessary to have continuous education on nutrition and social supports to prevent their dietary behaviors from leaning on convenience or preference.

It has been reported in animal and human studies that green tea shows a health protective characteristics. In the present study, we investigated the disease prevalence according to chronic green tea consumption in 92 subjects (mean age: 59.548.9, men: 41, women: 51) living in green tea cultivation village. The consumption of green tea and other life-style characteristics were ascertained by a questionnaire. The subjects were divided into three groups according to the period of green tea consumption (0, < 10 year, and $\geq$ 10 year). For green tea consumption groups, most of the subjects have been drinking green tea in order to protect disease and recognized the effects of green tea as detoxification of alcohol and smoking, protection of cold or release from fatigue. There were no significant differences in drinking and smoking, physical activity, and a cold prevalence among the groups. Green tea consumption was associated with lower levels of prevalence of tooth decay as well as the osteoporosis. The score of dietary habits was higher by increasing green tea consumption period (p<0.05). Consequently, chronic green tea consumption can be considerably effective in health promotion.

Based on the previous studies on alcohol effects on human behavior and performance in transportation system such as airplane and car driving, the alcohol exposure before and on watch of a ship has a great influence on subsequent behavior. In this paper, to examine the drinking status of officers on board multiple choice questionnaires are circularized under instruction and surveyed for 118 officers. According to the results of the questionnaire survey on alcohol dependance (Alcoholism) that was invested by WHO, over 27% of those surveyed represented alcohol abuse symptoms. In addition to that, the existing state and awareness for on-board-drinking was summarized to make a scenario of drunk-operation with a ship handling simulator to investigate the effect of alcohol (0.08 g% blood alcohol concentrations) on ship operational performance. A main effect for alcohol was found indicating that ship operational performance was comparatively impaired by this alcohol relative to performance in the non-alcohol condition. The results of this research can be applied to minimize marine acciedents as basic data.

The purpose of this study was to investigate nutrition knowledge, dietary habits, health related life style and health condition of 247 male and 244 female students at K University in Chuncheon. The results of the survey are summarized as follows: The average nutrition knowledge score and dietary habit score were 10.79 and 19.38 for male, and 10.89 and 19.48 for female, respectively. The percentage of those who smoked, drank and exercised regularly were 32.0%, 93.9%, 47.0% for male, and 6.1%, 91.8%, 24.6% for female, respectively. The health scores of the female (43.02) were significantly lower than those of the male (46.26) (p<0.001). On female students, significant correlation was found between dietary habits score and health score (p<0.01). College students are in early stage of adult life and their dietary habits, health related life style and health condition will be continued to their later life.
