Purpose: The purpose of this study was to identify the relationships among distress from drinking, alcohol abstinence self-efficacy and outcome expectancy in youths. Method: The participants in this study were 174 university students who were enrolled by convenience sampling. The data were collected from March to August, 2005. Descriptive statistics and Pearson's correlation coefficients with SPSS 12.0 were used to analyze the data. Results: There were significant differences in the physical distress from drinking according to gender, age, residence, drinking frequency and drinking capacity. There were significant differences in alcohol abstinence self-efficacy by drinking frequency and drinking capacity. There were significant differences in drinking outcome expectancy according to gender, drinking frequency and drinking capacity. The physical distress from drinking showed a significant positive correlation with alcohol abstinence self-efficacy (r=.312, p=.000) and negative correlation with drinking outcome expectancy (r=-.353, p=.000). Alcohol abstinence self-efficacy showed a significant negative correlation with drinking outcome expectancy (r=-.387, p=.000). Conclusion: There were relationships among physical distress from drinking, alcohol abstinence self-efficacy, and drinking outcome expectancy. These findings provide the basis to prevent problems of drinking by developing alcohol control program for university students.

To investigate the detoxificative effect of tea, five kinds of tea(mulberry, anaerobic treated mulberry, green, barly tea and corm tea) were selected and determined their dotoxication activities for Cd and Pb in drinking water. The effect of tea on the removal of Cd and Pb were increased proportionally to the contents of teas. Anaerobic treated mulberry leaf tea showed stronger detoxication activity than the others. In drinking water contaminated with Cd, the removal effect of Cd was high 27% by anaerobic treated mulberry leaf tea and 14% by mulberry leaf tea as compared to green tea. Also, in drinking water with Pb, the removal effect of anaerobic treated mulberry leaf tea was the best among five kinds of tea. Pretreatment method on the removal effect of Cd was better than post-treatment method in the treatment method.

Purpose: The purpose of this study was to identify the factors influencing drinking problems in female university students to provide basic data for a nursing intervention program to improve health and prevent drinking problems. Method: Data were collected from September 17 to 21, 2007 through a questionnaire survey of 325 female college students in G City. Collected data were analyzed using descriptive statistics, pearson correlation coefficients and stepwise multiple regression. Result: The most powerful predictor of drinking problems was refusal self efficacy. The combination of the influence of friends, perceived stress, personality of novelty seeking, and alcohol expectancy accounted for 23.7% of the variance in drinking problems. Conclusion: From the results, I recommend that refusal self efficacy, influence of friends, perceived stress, personality of novelty seeking, and alcohol expectancy should be contained in developing nursing intervention programs for preventing drinking problems in female university students.

Purpose: The purpose of this study was to investigate drinking motives and the drinking-related problems of Korean high school students at a city in Jeonbuk province. Methods: There were 657 students from two academic and two vocational high schools at J city in Jeonbuk province. The sample was collected using a stratified sampling method and the data was collected from June 30th to July 16th 2003. The study instrument used to examine drinking motive was a 20-item summated scale (Cronbach's ${\alpha}$ = .95) and for drinking-related problems was an 18 item summated scale (Cronbach's ${\alpha}$ = .91). The data was analyzed using SPSS/PC+ by percentage, x2-test, t-test and correlations. Results: 1. Drinking experience: Among the high school students, 74.3% of them had drinking episodes. Female students started drinking later (x2 = 12.857, p = .002) and had more drinking friends (x2 = 7.785, p = .020) than males. Vocational school students drank more frequently (x2 = 32.138, p = .001), had more heavy drinking episodes (x2 = 40.370, p = .001). 2. Drinking motives & Drinking-related problems: The mean score of drinking motives was $31.2{\pm}11.12$ out of 80 and that of drinking-related problems was $21.8{\pm}5.85$ out of 72 points. Neither score were stronger was significantly different according to gender and grade. On the other hand, both drinking motives (t = -4.077, p = .001) and drinking-related problems (t = -3.423, p = .001) were stronger in vocational school students than in academic school students. The correlation between drinking-related characteristics and problems were weak (from r = .286 to r = .520) but the correlation within the subcategories of drinking motives was high such as between enhancement and coping (r = .822) and enhancement and social motives (r = .822). Conclusion: The majority of Korean high school students start to drink during their junior high school days. Drinking motives and drinking-related problems were not serious but the drinking motives and the drinking-related problems are stronger among vocational school students. As a result, school-based health education and counseling programs should focus on solving drinking motives than on drinking-related problems.

The analytical methods for dioxins in water sample from wastewater to tap water were reviewed. For extraction method, liquid-liquid extraction (LLE) has been widely used, however, this process needs too much time and man power. New approach including solid phase extraction (SPE) is now applicable to large volume of water sample with high extraction efficiency. Column clean up in classical analytical methods were very complex and time consuming procedures during decade. Modifications were tried to decrease solvent and reagents volume. Moreover, use of column connection method has been demonstrated in the environmental matrices. Instrumental configurations also have been improved, in which GC/MS/MS with large volume injection approach can analyze picogram levels. Absolute sensitivities of HRMS increased compared to old versions of double focusing sector type mass spectrometers. Based on these analytical evolutions during last 10 years, we tried to optimize the analytical method for dioxins in water sample from sample extraction to instrumental analysis.

Today, a definition of tourism is shifting from simple sightseeing to experiencing various cultures directly and/or indirectly. Along with the shift, all countries of the world dedicate their full attention on globalization project. In order to do so, they try to promote their images and cultures through eating and drinking spaces for food where the rest of the world can approach with ease. China is a country of diverse culinary culture. By analyzing eating and drinking spaces operated in four Chinese cities, this research studies how the traditional Chinese elements are expressed in modernization. With the research, it will navigate a direction as a new design way to establish modernized traditionality in the future. The research conducted an advanced research that set up and analyzed a standard frame of realizing practice for traditionality. By doing so, it sorted out and reviewed the characteristics of interior space into four styles; an indicative imitation method, a partial invoked method, a partial transformation method and a conceptual reception method. According to the outcome of an analysis, (a) the indicative imitation method that directly employed Chinese tradition was most used one, followed by (b) the partial invoked method that carried a part of traditional space, (c) the partial transformation method that simplified or transformed the tradition, and (d) the conceptual reception method that interpreted hidden minds and concepts by illustrating modern spirit over an inherent order in traditional Chinese space, in respective order.

Purpose: This study investigated the prevalence of drinking behavior among elementary students, and the results may serve as the basic data for developing a drinking prevention program. Method: For this study, questionnaires were given to 734 fourth, fifth and sixth graders in five elementary schools in U county, North Chungcheong Province. The data was were collected from December 8 to December 20, 2003 and the data was analyzed using SPSS/PC for the descriptive and chi-square statistics. Results: Of these students, 72.8% reported that they had drunk alcohol. They reported that the first drinking started during the third and fourth grade (37.8%), at family gatherings (41.0%), and by mistake (26.0%). They reported that alcohol was tasteless when they first drank (53.1%). The drinking experiences were significantly related to gender. Similarly, environmental characteristics such as the residential area, parental attention, the home atmosphere, and drinking parents were significantly related to drinking behavior. Among the non-drinkers, 70.5% intended not to drink and 6.5% reported they would like to drink in the future. Conclusion: This study suggests the necessity of developing drinking prevention programs with considering the students' demographic and environmental characteristics.

We investigated springs in Seoul in 2009 to know the change of water quality according to storage method of spring water, the concentration of chemical compounds and their correlation. Even spring water that originally satisfied national standard for drinking water could be exceeded national standard for drinking water by storage method such as storage bottle, temperature and period; especially used PET bottles could affect the increase of total colony counts. Therefore, spring water is desirable to be consumed on the spot, or to be stored in sterilized bottles in refrigerator rather than room temperature at home, and also to be consumed shortly not exceeding 24 hours. Total colony counts, coliform, yersinia, $F^-$, $Cl^-$, $NO_3^--N$, hardness, total Solids, pH, color and Al were exceeded national standard for drinking water at some springs. The result of correlation analysis shows that hardness and total solids, which are caused by several ionic compounds, had relatively high correlations with other chemical compounds.

Due to the stringent drinking water quality, formaldehyde will be included in Korean drinking water standard from year 2014. However, its standard analytical method has not yet been established. This study compares two analytical methods, DNPH-LC and ACFAS with respect to their analysis principles, Method Detection Limit (MDL), Limit Of Quantitation(LOQ), precision, accuracy, reproducibility, convenience, number of samples analyzed per hour and analysis cost. These methods measure absorption intensity at 360 nm by using HPLC after DNPH-derivatization (DNPH-LC) and at 410 nm by using Automated Continuous Flow Absorption Spectrophotometer (ACFAS), respectively. Reproducibility was tested by repeating the analysis 7 times using a standard solution for each method. For DNPH-LC method, MDL was $0.5{\mu}g/L$, LOQ was $1.58{\mu}g/L$ with standard deviation of $0.16{\mu}g/L$. For ACFAS method, they were $0.27{\mu}g/L$, $0.85{\mu}g/L$L with standard deviation of $0.09{\mu}g/L$, respectively. Both methods satisfied the requirement set by the Korean drinking water quality standard. Complexity of sample pretreatment procedure for DNPH-LC method may cause large error and, consequently, the analytical result will depend on the level of skill of analyst. In contrast, ACFAS method which used only one reagent equipped with an automated injection device showed little analytical error. It costs about $5.00 and $1.00 for one sample to analyze by the DNPH-LC method and the ACFAS method, respectively. Compared to the DNPH-LC method, ACFAS method provided more reliable analytical results. In terms of convenience, easiness and analytical cost, ACFAS method was demonstrated to be superior to the DNPH-LC method. The results of this study suggested that the ACFAS method could be adapted as a proper method for determining formaldehyde content in drinking water.
