The purpose of this study was to examine the smoking-related characteristics of health and non-health related majors and the relationship between the smoking dependence and oral health practice of college students. The subjects in this study were the college students who were selected by convenience sampling from four different universities in the city of Jeonju, North Jeolla Province. The answer sheets from 811 respondents were analyzed. The findings of the study were as follows: The rate of the smoker students whose major was related to health stood at 20.6 percent, and that of the smoker students whose major was not related to health stood at 29.4%. There were significant differences according to the track of their major (p<0.05). As for links between smoking dependence and a plan to quit smoking, 32.7% of the health-related majors who considered themselves to depend on smoking replied they would give up smoking if there would be a rise in cigarette price (p<0.005), and 37% of the nonhealth related majors who considered themselves to depend on smoking gave the same answer. Thus, the largest group of the students intended to quit smoking if there would be a rise in cigarette price, and there were statistically significant differences according to smoking dependence (p<0.05). Concerning connections between smoking dependence and actual oral health practice, the non-health related majors who didn't consider themselves to depend on smoking got 3.53 in the item whether they brushed their teeth twice or more a day (p<0.05). In conclusion, the development and implementation of systematic programs that are to teach students to stay away from or quit smoking and take care of their oral health regardless of their major are required to step up the oral health promotion of college students.

Smoking is one of the three major risk factors for vascular disease along with hypertension and hyperlipidemia. It is true that smoking has a negative effect on the circulatory system, and the frequency of coronary artery disease and peripheral vascular disease is significantly increased in smokers. Many epidemiological studies report that smokers have an approximately two-fold increased risk of coronary artery disease compared to non-smokers. This study was designed to investigate the relationship between cerebral blood flow change and depression index after acute smoking. Cerebral blood flow tests were performed before and after smoking in 8 subjects. Changes in blood flow after smoking were correlated with the depression score and negatively correlated with the depression score. In particular, there was a strong correlation with changes in blood flow in anterior cerebral artery. It is well known that changes in blood flow after smoking have a negative effect. In addition, considering the study that smoking aggravates the symptoms of depression, it was found that smoking and depression are factors that negatively affect each other.

Object:Nicotine dependence is the most common substance abuse disorder. One of the characteristics of nicotine dependence is craving. Regional activation of the brain induced by craving for nicotine was evaluated by using functional magnetic resonance imaging to investigate neuroanatomical site of smoking craving. Method:A smoker who satisfied DSM-IV criteria for nicotine dependence and a non smoker was studied. MRI data were acquired on a 1.5T Magnetom Vision Plus with a head volume coil. Two sets of visual stimuli were presented to subjects in a random manner. One was the film scenes of inducing smoking craving and the other was neutral stimuli not related to smoking. There were two fMRI sessions before and after smoking or sham smoking. Data were analyzed using SPM99. Results:fMRI showed significant activated area in anterior cingulate and medial frontal lobes in the smoker during smoking craving. Right dorsolateral prefrontal cortex and parietal lobes were activated in the control during visual stimulation before smoking. After smoking, there was no brain activation during visual stimulation in both of smoker and non smoker. Conclusion:Metabolic activity of the anterior cingulate and medial frontal lobes increased during craving for smoking. This result suggests that fMRI may be a valuable tool in the identification of neurobiological process of craving.

The purpose of this study is to examine the effectiveness of video-and discussion-based smoking cessation intervention for adolescents. And this study is intended to provide a basic database for the development of health education, to serve health promotion for adolescent. The subjects were 472 high school students in K yungkido. The data was collected from September 23th to October 31 st, 2002. The data was collected by the measurement of knowledge, attitude, and intention toward smoking. Pre-research was conducted before smoking cessation education and post-research was performed twice, immediately after the education and 4 weeks later. Collected data was analyzed by using the SPSS 10.0 which is a computational statistical program. The results of this study are as follows： 1. Total knowledge points in smoking cessation program-based group are higher than any other groups and the statistical difference is significant. 2. The students' attitude points in experimental groups are higher than that of the control group and the statistical difference is significant. However, the meaningful statistical difference disappeared after 4 weeks. 3. The non-smoking students' intention points do not show any significant difference. And the smoking students' intention points in experimental groups are higher than that of the control group but the statistical difference is insignificant. 4. There are correlations among knowledge, attitude and intention toward smoking： knowledge and attitude are negatively correlated, knowledge and intention are positively correlated for non-smoking students, and for smoking students, attitude and intention have a negative correlation.

The purpose of this study was to investigate the effect of smoking on dietary behavior and nutrient intake among the male college students. The subjects were divided into three groups; non smoker(n=84), moderate smoker(n=68), and heavy smoker(n=89) according to duration and degree of smoking. And they were asked for general characteristics, life style, eating pattern, food frequency, and nutrient intake using questionnaire and 24-hr recall method. The mean age, height, weight, and BMI of the subjects were 26.2$\pm$6.2 years, 173.3$\pm$5.3㎝, 66.5$\pm$9.3㎏, and 22.1$\pm$2.7㎏/$m^2$, respectively. The type of residence and frequency of alcohol drinking were significantly different among three groups; the frequency of self-boarding and alcohol drinking in moderate smoker and heavy smoker was higher than those in non smoker. Comparing with non smoker, the frequency of skipping meals, especially breakfast and supper, was significantly high in moderate smoker and heavy smoker. The most common reason why heavy smoker skipped meals was ‘eating habit’, while it was ‘lack of time’ in non smoker. The results showed that the heavy smoker tended to drink coffee more often compared to the other two groups. There were no significant differences in nutrient intakes among three groups. In conclusion, heavy smoking students have unhealthy dietary behaviors in terms of high frequency of alcohol drinking, habit of skipping meals and frequent coffee drinking showing a strong need of proper education on smoking withdrawal and meal practice for them.

This research compared the features of respiration and phonation between practical musicology students and general male students, according to their smoking status. Participants of this research are 15 practical musicology male students attending ${\bigcirc}{\bigcirc}$ university and 16 general ${\bigcirc}{\bigcirc}{\bigcirc}$ university students. The participants, both non-smokers and smokers with 5-years of smoking history have no history of voice disease in any case and have normal cognitive functions. The results indicated that, first, there is not a notable difference in the respiratory activity status(FVC, FEV1, FEV1/FVC), regardless of major and smoking status. In MPT, even though there is no significant difference in accordance with their majors, considering smoking status, the smoker group was shorter than non-smoker group significant difference statistically (p<.01). Second, the divisions of participants' major did not show significant difference in Fo, jitter, shimmer, and NHR in the vowel prolongation task. However, the smoker group showed a significantly higher degree of jitter and shimmer than the non-smoker group (p<.05) as Fo and NHR shows no difference. In the case of VRP, maximum frequency and frequency range of the practical group are significantly higher than normal group statistically (p<.001). Moreover, although the difference of the minimum frequency shown at the statistic is not significant, practical group showed a higher tendency of frequency than normal group (p=.051). In conclusion, even though there is no difference in respiratory activity between the smoker group and non-smoker group, the MPT of the smoker group is shorter than that of non-smoker group. In addition, the smoker group showed a higher degree of jitter and shimmer than the non-smoker group. MPT is related to the valve action of vocal fold that passes through the glottis. Thus, it is interpreted that the smoker group has a lower quality of voice and valve action of the vocal fold. Also, the practical group has a higher degree of maximum frequency and frequency range than the normal group. This research can function as basic data for vocal characteristics for the majors in relation to the voice-specializing.

Purpose: The purposes of this study were(a) to identify smoking behavior by following a cohort representative of the population of 4th grade elementary schoolers in South Korea over a four-year period(2004-2007), and(b) to explore predictors of smoking initiation among non-smokers in Wave 1. Methods: Secondary data, the Korea Youth Panel Study, was analyzed in this study. First, frequencies or percentages were calculated to identify smoking behavior(i.e., smoking initiation, smoking intensity, and smoking duration). Second, binary logistic regression analysis was performed to examine significant factors related to smoking initiation. Results: Smoking initiation and daily smoking were more pronounced when the participants entered middle school. In bivariate analysis, statistically significant predictors of smoking initiation were loneliness at school, self-control, delinquent behavior, depressive symptoms, and stress. However, after controlling for other factors, only a high level of risk-taking tendency and a greater number of delinquent behaviors remained statistically significant. Conclusion: Based on greater involvement in smoking among first-year middle schoolers, smoking prevention strategies should be provided to elementary schoolers rather than middle schoolers. A risk-taking tendency and delinquent behaviors should be considered as proxy measures to detect the high-risk group for smoking initiation.

Objectives : To evaluate the impact of the workplace smoking ban in South Korea, where the male smoking rate is high (57%), on smoking behavior and secondhand smoke exposure. Methods : A workplace smoking ban legislation implemented in April 2003 requires offices, meeting rooms, and lobbies located in larger than 3,000 square meter buildings (or 2,000 square meter multipurpose buildings) should be smoke free. A representative cross-sectional survey, the third wave (2005) of health supplements in the National Health Nutrition Survey of South Korea, was used to measure the impact of the 2003 workplace smoking ban implementation on smoking behavior. It contained 3,122 observations of adults 20 to 65 years old (excluding selfemployed and non-working populations). A multivariate statistical model was used. The self-reported workplace smoking ban policy (full workplace ban, partial workplace ban, and no workplace ban) was used as the key measure. Results : A full workplace smoking ban reduced the current smoking rate by 6.4 percentage points among all workers and also decreased the average daily consumption among smokers by 3.7 cigarettes relative to no smoking ban. Secondhand smoke showed a dramatic decrease of 86 percent (= -1.74/2.03)from the sample mean for full workplace ban. However, public anti-smoking campaign did not show any significant impact on smoking behavior. Conclusions : The full workplace ban policy is effective in South Korea. Male group showed bigger impact of smoking ban policy than female group. The public antismoking campaign did not show any effectiveness.

This study examined the effects of a non-smoking program according to the stress and emotional condition of male office workers. As research subjects, 106 smokers at C company who participated in the campaign of "No Second-Hand Smoking and No Cigarette Smoke at Work" from April 25, 2011 to December, 2011 for 8 months were enrolled in this study. Apreliminary survey of the general characteristics, motivation to quit smoking, emotional condition, behavior to cope with stress, stress in life, hope, and the emotional variables of job satisfaction in the research subjects was carried out. The study undertook a pre-and-post effect analysis of the non-smoking program only with those who succeeded in quitting smoking. In terms of the general characteristics of the subjects, the success rate of quitting smoking was higher in those in their thirties and above and those who were married. No significant difference in the emotional variables was observed between those who were not successful and those who were. These results suggest that the motives for stopping smoking and effective dealing with stress or anxiety is important for male office workers to succeed in stopping smoking, based on which smoking cessation programs should be developed. In addition, the message of a smoking cessation campaign should be designed specifically for each target audience, effectively emphasizing the emotional aspects of each target group.

Purpose: Sitting time, smoking, and perceived stress strongly influence physical health independent of physical activity. However, the associations among perceived stress, sedentary behavior, and smoking are poorly understood. Therefore, we examined the relationships between sitting time, smoking, and perceived stress in Korean adults aged < 65 years. Methods: We analyzed data from the seventh National Health and Nutrition Survey. In this cross-sectional study, data from 6,890 Korean adults aged < 65 years were analyzed. Complex-sample logistic regression was used to examine the relationships between sitting time, smoking, and perceived stress. Results: The group with a high sitting time (≥ 8 h/day) and those who smoked had significantly higher odds of experiencing stress than the low sitting time (< 8 h/ day) and non-smoking groups (odds ratio: 1.88, 95% confidence interval: 1.42-2.50). Conclusion: Perceived stress was positively correlated with current smoking status and increased sitting time. High sitting time (≥ 8 h/day) and current smoking were associated with a higher risk of perceived stress in Korean adults aged < 65 years.
