Objectives: This study was conducted to investigate the awareness of energy drinks, energy drink consumption behaviors, and associated factors among college students. Methods: A total of 536 students from three universities in Cheongju completed a self-administered questionnaire regarding awareness and consumption of energy drinks as well as general characteristics, health-related characteristics, and eating habits. Results: Approximately half of the respondents reported they knew what energy drinks were, while 45.7% had heard of energy drinks but did not know what they were. However, 76.9% had experience in using energy drinks. The main reason for using energy drinks was to stay awake, and the main place that they were used was on campus or at the library. More than 70% of energy drink users did not read the caffeine contents of energy drinks. After consuming energy drinks, 31.3% experienced adverse effects, the most serious being sleep disturbance. Approximately 33% of students consumed energy drinks once a month or more frequently, and men consumed energy drinks more frequently than females. Energy drink users who consumed at least one drink each month were more likely to be natural science major or drink more milk for male students, and to have more allowances or consume less meat for female students, compared with non-users. Conclusions: Our study showed that 33% of students consumed at least one energy drink each month, and there were a small number of students consumed energy drinks almost every day or energy drinks mixed with alcohol. Accordingly, college students should be taught potential health hazards of energy drinks mixed with alcohol as well as energy drinks alone. In addition, reading labels about caffeine and sugar contents in energy drinks is encouraged.

Speech language pathologists depend on their voice for livelihood and are high risk group of voice disorders. But there are few studies on their prevalence of voice symptoms and voice handicap index. This study aimed to evaluate prevalence of voice symptoms and Korean voice handicap index with 86 speech language pathologists and 90 individuals employed in other occupations. We analyzed self-reported voice symptoms and voice handicap index using a questionnaire for this study. The results showed that the prevalence of voice symptoms of speech language pathologists is 60.5% and voice handicap index scores of speech language pathologists group are significantly higher than those of control group in physical and total score. And we found that alcohol history was a risk factor for voice symptoms. These findings indicate that special vocal hygiene program for speech language pathologists and follow up studies for comparisons of prevalence of voice symptoms and voice handicap index with other professional voice users are necessary.

The study is designed to compare differences between male and female Internet users in present Internet use conditions, Internet addition, self-respect, and deviation from a health life and analyze and understand factors causing compulsive Internet use. The research is aimed at suggesting basic information to guide a desirable direction for healthy and effective Internet use. The survey of 456 students majoring in public health at some universities in the Pusan-Kyungnam areas was made in November, 2006. The results are as follows: As for general information on those surveyed the number of the males was 50(11.0%) and that of the females was 406(89.0%), which shows an absolute higher ratio of the female respondents. On a question of Internet use frequency 62% of the male students and 44.6% of the female students answered they use the Internet everyday. Also the male respondents' Internet use time was longer. 64.0% of the male students use the Internet for games and entertainment, which were the highest ranked reason. 64.4% of the female students said they use the Internet to check e-mails. To all the questions assessing Internet addiction, the male users' answers implied higher addiction levels, but there wasn't statistically significant difference. However, the statistically outstanding distinction between the two sexes on deviation from a health life is shown in smoking, cheating in a test, obscene video/books, and conflicts with parents. The most answered deviations among the male respondents are smoking, cheating in a test, and obscene video/books, while conflicting with parents is for the female students. On self-respect the survey has found statistical differences in five questionnaire items and the female showed higher levels in all those questions. The male students answered cheating in a test(0.399), conflicts with parents(0.391), and Internet use time(0.242) have significant plus(+) influences on their compulsive internet use, while alcohol(-0.308) has a minus(-) influence. The female students answered self-respect(0.114), alcohol(0.097), obscene video/book (0.218), conflicts with parents (0.243), and Internet use time (0.284) factors have plus(+) effects.

Drug dependence deals a heavy socioeconomic burden to the society. For adolescents, the damage from drug dependence is greater than adults considering their higher susceptibility to drug effect and increasing chance for violence leading to criminal punishment process. Habitual drug use depends on genetic and environmental factors and the complex interactions between the two. Mammalian model systems have been useful in understanding the neurochemical and cellular impacts of abused drugs on specific regions of the brain, and in identifying the molecular targets of drugs. More elucidation is required whether biological effects of drugs actually cause the habitual dependence at the cellular level. Although there is much insight available on the nature of drug abuse problems, none of the systems designed to help drug dependent individuals is efficient in screening functional ingredients of the drug, and thus resulting in the failure of helping drug dependent individuals recover from drug dependence. Alternative model systems draw the attention of researchers, such as the invertebrate model systems of nematodes (Caenorhabditis elegans) and fruit flies (Drosophila melanogaster). These models should provide new insight into the mechanisms leading to the behavior of drug users (even functional studies analyzing molecular mechanism), and screening useful components to help remove drug dependence among drug users. The relatively simple anatomy and gene expression of the invertebrate model systems should enable researchers to coordinate current knowledge on drug abuse. Furthermore, the invertebrate model systems should facilitate advance in experiments on the susceptibility of specific genetic backgrounds and the interaction between genetic factors to drug dependence.

The food composition tables are frequently used to health and nutrition practices. But it is difficult to find out food exchange lists with food exchange groups in the food composition table. Over 2500 items and many kinds of nutrients are in the food composition table. But now food exchange lists are used a few foods. The internet demands the users needs for obtaining more food exchange lists and nutrient information from food composition. This basic study is to solve the users need and the supply more efficient and effective manipulation system for e-food exchange database construction and search system:ENECC/e-food exchnage(E-Nutrition Education and Couseling Center/e-food exchange). This paper introduces the food exchange database construction and search system(ENECC/e-food exchange) using the formula which calculates the food exchange quantity of 6 food exchange groups and added one extra groups(alcohol) based on the internet. The ENECC/e-food exchange database is basically based on the 6th food composition table(2001) of the National Rural Living Science Institution in Rural Development Administration, Korea. The e-food exchange database are consisted of 2,261 foods in 6 basic food groups and one extra groups by using ENECC calculating formula. Also, the e-food exchange database has the proximate composition, mineral and vitamin content such as energy, moisture, protein, fat, carbohydrate, ash, calcium, phosphorus, iron, sodium, potassium, retinol equivalent, retinol, â-carotene, thiamin, riboflavin, niacin, ascorbic acid, refuse per 100g of each food.

The purpose of this study was attempted to analyze the relationship between drug abuse and the other problem behavior Patterns among high school students in Cheju. In order to achieve these set-goals, questionaires were finally supplied to the total 379 case of 9 high school from October to December, 1990. The collected data were processed using the SPSS-X computer program and statistically analyzed by the Chi-square method and. percentage. Results of the study were as follows: Among the 370 adolescents, 32.4% of students experienced cigarette smoking in their life, adolescents who experienced alcohol drinking were 46.8%, 0.5% of the students ever used marihuana; cocaine 0.3%, stimulant 3.2%, hallucinogen and inhalants 0.5%, tranquilizer 1.4%, analgesics 31:6%, antitussives 6.5%, antihistamines 1.9%. And all students never experienced the amphetamines and narcotics. The rates of drug use except stimulant and antitussive were higher in the male than in the female students. For the analysis of personal identifying datum, the rates of experienced smokers increased among groups of buddhist and the rates of experienced alconoi drinking increased among groups of no religion. Drug abuser increased among the group lower socio-economic status student, the adolescents whose parents have traditional education point of view. And it was also higher in those who were living only one than in those who were living together. Most students tended to use drugs after 17 or 18 years old. Drug users were more inclined to commit other problem behaviors when compared non-drug users. In the conclusion of the above results, it will be necessary to investigate the drug problem of adolescent. Drug abuse of students must be seen in an environmental context including family, school, peer group and society and not solely as the characteristics of an individual adolescent. And their parents and teachers must be on the alert for the behavior changes of their children such as changes of school performance, neglecting homework, tardiness or truancy from school, runaway from home, and mingled with bad companions, etc. We must recognize that drug abuse is frequently symptomatic of problems in the adolescent's environment.

The purpose of this study was to examine changes in acoustic characteristics after drinking alcoholic beverages and singing in order to establish guidelines for vocal hygiene of both singers and non-singers. 21 university students (10 males and 11 females) vocalized /a/ before drinking, after drinking and after singing. Changes in vocal range and acoustic characteristics were analyzed by Dr. Speech 4.0 (Tigers Electronics). No significant difference was observed in vocal range following drinking. However, there was statistically significant changes in vocal range after singing. We may infer that appropriate amount of singing functioning as vocal warm-up, rather than drinking alone, resulted in improvement in their abilities to lengthen vocal folds. This is directly related to the ability to produce high-pitched sounds. Changes in jitter in female voices after singing was the only acoustic factor that was significant. Changes in Shimmer and NNE was not significant either after drinking nor singing. Subjects who were judged to perform better in singing were marked by minimum acoustic changes, which may due to their well-trained vocal fold function. The results of this study may address the necessity for vocal function exercises for the patients with neurogenic voice disorders including dysarthria. The need for more extensive research with a larger number of subjects including professional voice users is also addressed.

Information technology has economic, social and cultural impacts is closely linked to our lives. This information technology is becoming a key to the change of human civilization through connecting people and objects on the earth. In addition, future information technology is becoming more intelligent and personalized with the development of computing technology, and due to the rapid development of alcohol, environment without time and space constraint is realized, Is spreading. Since existing portable storage media are made of physical form, there is a limit to usage due to the risk of loss and limitation of capacity. Cloud services can overcome these limitations. Due to the problems of existing storage media, it is possible to overcome the limitations of storing, managing and reusing information through cloud services. Despite the large number of cloud service users, the existing research has focused mainly on the concept of cloud service and the effect of introduction on the companies. This study aims to conduct a study on individual characteristics that affect the degree of cloud use. We will conduct research on the causes of IT knowledge, personal perception of security, convenience, innovation, economical trust, and platform dependency affecting the intention to use the cloud. These results show that the variables affecting individual 's use of cloud service are influenced by individuals, and this study can be used as a basic data for individuals to use cloud service.

This study was conducted to investigate the factors related to smoking and smoking differences among adolescents who have experienced smoking using data from the 11th (2015) Korean Youth Risk Behavior Web-based Survey. The data used in this study were from 5,347 middle and high school students who had cigarette smoking and electronic cigarette smoking experience among 68,043 respondents to the 11th (2015) Korean Youth Risk Behavior Web-based Survey. The data were evaluated by frequency analysis, the ${\chi}^2$ test and logistic regression analysis using weighted composite sample analysis. Overall 20% of the total smoking adolescents were dual users and 85.6% of the users of electronic cigarettes used nicotine. The results from multinomial regressions show that: male students (OR 1.63; 95% CI 1.15-2.31), living in the metropolitan area (OR 1.76; 95% CI 1.32-2.33), an average consumption of fast food of once or twice a day (OR 2.48; 95% CI 1.33-4.64), first started smoking during high school (OR 0.76; 95% CI 0.58-0.98), having experience with passive smoking (OR 1.24; 95% CI 1.07-1.44), experience drinking alcohol (OR 2.03; 95% CI 1.65-2.48) and those with higher weekly allowances were more likely to be at risk than dual users. This study provides basic data regarding the dual use of electronic cigarettes and cigarettes by adolescents. The results presented herein will facilitate development of a smoking cessation program and policy.
