Objectives : The purpose of this study was to investigate attitudes toward and practice of oral health management among adults in the Gumi area. Health behavior especially drinking and smoking have been proven to affect the tissues around the teeth and increasing in importance. Thus the study set out to examine oral management according to drinking and smoking to suggest a need for education about oral health and provide basic data for oral health education. Methods : Total 226 subjects, who consist of 141 male adults and 85 female adults, in Gumi were asked to fill out a self-administered questionnaire on October 24, 2009. Their answers to the items about general characteristics, health behavior, and oral health behavior were analyzed with the SPSS WIN 12.0 program. Results : 1. As for the frequency of visiting a dental clinic(hospital) for the last year, the non-movement group recorded higher frequency than the movement group, and the drinking group also did than the non-drinking group(p<0.05). 2. As for the experience and frequency of scaling, the female subjects were higher in the experience and frequency of scaling than their male counterparts. The older they got, the more they tended to have scaling. The married respondents had more experiences of scaling than the singles, and the non-drinking group was high in the experience of scaling(p<0.05). 3. As for the number, time, and method of toothbrushing a day, more women answered they brushed teeth three times or more per day than men; those who were in their forties were the highest in terms of the roll method, and those who were in their twenties were the highest in terms of toothbrushing time. The married group and the non-smoking group answered they brushed teeth in the roll method three times or more per day in higher percentage. And the non-drinking group was high in the roll method, which was statistically significant(p<0.05). 4. As for use and kinds of auxiliary oral hygiene devices, the female respondents used them more than their male counterparts. The older they became, the more they used them. The married group, the non-smoking group, and the non-drinking group used such devices a lot. The smoking group used dental floss most, and the non-smoking group used more kinds of such devices than the smoking group, which was statistically significant(p<0.05). Conclusion : Oral diseases can be prevented by adopting healthy and right oral management behavior. Using the findings of the study, more diverse programs about actual oral health education should be activated so that people can change their bad oral management and behavior and develop a habit of the right oral management attitude.

Objectives: This study is to examine that drinking problems among university students were accounted for not only by student's individual characteristics but alcohol policy and environmental characteristics of the university in which students were enrolled. Method: Secondary data analysis was employed in which variables under study were derived from a raw data of a nationwide representative sample in 2009. Raw data under analysis included 3,665 students from 63 universities across Korea. Organizational and environmental characteristics of the university were collected from university administrators while individual characteristics and drinking behavior from the students in using self-administrated questionnaire. Multilevel regression analyses were employed to describe alcohol policy effects on students's drinking problems measured by AUDIT by using HLM7.0. Results: ICCs indicate that variation in drinking problem depends on alcohol policy of university. Multilevel regression models identified statistically significant factors in explaining variance of drinking problems. Group means on drinking problem are affected by indicators representing alcohol policy with level of drinking problem of student being decreased in accordance to level of availability of alcohol on campus. Conclusions: It is concluded that drinking problems among university students were associated with both individual characteristics and alcohol policy of the university they enrolled. This study supports policy belief that interventions at environmental as well as individual level are required to prevent drinking problem among university students.

Objectives : It is well-known that Korean people show distinctive drinking behaviors depending on the gene polymorphisms of alcohol metabolizing enzymes. This study examined the gene polymorphisms of ALDH2 and ADH1B and their combination on the drinking behaviors of Korean young adults. Methods : Through a follow-up survey performed for a cohort consisting of 551 university freshmen for six years, the authors attempted to identify genetic factors affecting drinking behaviors. In 2000, drinking behaviors and scores of CAGE questionnaires were assessed and ALDH2 gene polymorphism was determined with PCR-RFLP. In 2006(n= 150), AUDIT-K was assessed in addition to the above and gene polymorphism of ADH1B was determined through SNaPshot$^{TM}$ method. Results : While ALDH2*2 allele was associated with increased degree of drinking in 2000 and 2006. When both enzymes were active, the possibility to be classified into the risk group for alcohol dependence such as AUDIT-K(>12), and CAGE(>2) was high. Conclusion : The ALDH2 genotype had a significant effect on drinking behavior and degree of drinking during early adulthood. However, the combination of the active form of ADH1B and the active form of ALDH2 can be risk factor for problem drinking.

Purpose : Although quantitative research on alcohol consumption among nursing students is important, qualitative research is needed to determine the subjective views of individual students, such as their feelings and thoughts, and ensure the implementation of a targeted alcohol intervention program. Q-methodology is a systematic approach that examines the subjective perspectives of individuals, including their views, beliefs, and attitudes, enabling understanding of the types and characteristics according to the individual's subjectivity structure. This study examined the subjective perceptions of drinking among freshmen in nursing college using Q methodology. Methods : Q-sorting was conducted, collecting 38 P samples and 40 statements. The data were analyzed using the PC QUANL program. The principal component factor analysis method was used for Q-factor analysis. Results : The results identified four types of drinking perceptions among freshmen in nursing college. Type 1 was "safety and health pursuit," type 2 was "friendship pursuit," type 3 was "'norm-oriented," and type 4 was "sound manners." When looking at the subjective perceptions of drinking among freshmen in nursing college, there was a common opinion that drinking should not be forced and that it is an individual choice. However, the difference in views (positive and negative) of drinking shows the need for customized educational programs and interventions suitable for each type. Conclusion : Nursing freshmen should be prepared to play an important role in health care as an educational role and model in preventing damage from drinking and maintaining health promotion throughout their life by habituating proper drinking behavior during college life. In addition, it is necessary to develop a plan to increase positive awareness of drinking among nursing students through various strategic programs that can participate in sobriety prevention programs within the university.

A new procedure for the concentration of nonoviruses from water samples has been developed. This procedure (calcium flocculation-citrate dissolution method) uses the following steps: virus flocculation formed by treatment with 1 M $CaCl_2$ and 1 M $Na_2HPO_4$, virus release by sodium citrate dissolution (0.3 M Na citrate, pH 3.5), and virus re-concentration by ultrafiltration. When reverse transcription (RT)-PCR was performed after the procedure, the overall detection sensitivity for seeded noroviruses in a one liter drinking water sample was as low as 1 RT-PCR unit, which is equal to a $10^{-6}$ dilution of the virus sample. This approach showed at least a 5-fold-higher sensitivity than the current method with its three steps of adsorption-elution-concentration. The newly developed procedure was used to test different brands of bottled drinking water from China for putative contamination with noroviruses. A total of 144 samples were analyzed; all of the samples were negative for norovirus specific nucleic acids.

This research is conducted to develop predictable method of real scale nanofiltration treatability with small scale nanofiltration experiments. As a result of comparing calculated values with measured values, they are in a good agreement for the concentrations in filtered water and concentrated water. The results of that are not affected by change of system recovery from 20% to 95%. The proposed method is produced using constant recovery of elements, that is, no considering the pressure change. we can predict filtrated flux and contaminant concentrations with the method. The method has the following steps. (1) Calculate recovery of each element with water quality level after fixing recovery elements, (2) Predict system recovery with recovery of elements in 1, 2, 3, and 4 banks, (3) Run small scale nanofiltration experiments in predicted water quality and (4) Simulate large scale nanofiltration system for forecasting actual water quality. As the cost for nanofiltration pretest will reduced if we use the proposed method, it will be a promising method for introducing nanofiltration to supply safe drinking water.

The purpose of this study was to analyze the factors affecting the drinking behavior of adolescents. Based on this, it aims to suggest the practical and policy measures to prevent the drinking behavior of adolescents and to mediate / reduce them. We used binomial logistic analysis as an analysis method.As a result of this study, the individual factors affecting alcohol drinking were gender, smoking experience over the past year, sexual satisfaction, cyber delinquency, self-esteem, parental abuse, peer as family factors. Peer trust was significantly associated with attachment factors, and school adaptation factors were not found to be associated with alcohol drinking in adolescents. This suggests that multilateral efforts such as individuals, families, and communities are needed to mediate and reduce the drinking behavior of adolescents.

Objectives: This study examined how adolescents' cognitive stress relates to suicidal thought, thereby offering basic data about social and institutional ways to reduce adolescent suicide. Methods: In this study, data from an online survey on adolescents' health conducted by Korea Center for Disease Control(2013, 9th) was used after altering it to fit the purpose of the study. The data was analysed using the complex sampling method and structural equation model(SEM). Results: Whilst adolescents' cognitive stress had positive effects on suicidal thought, problem drinking and cognitive depression, it had a negative effect on physical activity. The structural equation model from cognitive stress, problem drinking, cognitive depression, physical activity influenced suicidal thought. Problem drinking on the other hand had an influence on cognitive depression. Conclusion: These findings suggest that future intervention programs for prevention of adolescents' suicidal thought should also address problem drinking, cognitive depression, and cognitive stress.

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.
