Objectives: This study was conducted to analyze the relationship between smoking and denture wear in the elderly individuals aged 65 years and older, and a total of 3,112 people were included. Methods: A complex sample chi-square test was performed for denture wear according to general, smoking, and smoking-related characteristics. Factors related to denture wear were assessed using multiple logistic regression analysis. Results: Among non-smokers, present smokers were 4.192 times more likely to wear dentures, and former smokers were 2.195 times more likely to wear dentures. The average number of daily past smokers was 0.564 times less likely to wear dentures if they smoked 15 cigarettes or less per day. Conclusions: Smoking among the elderly and wearing dentures are related, and it is necessary to develop and utilize a smoking cessation education program considers socioeconomic characteristics.

Purpose: Much evidence suggests long-term cigarette smoking alters coronary vascular endothelial response. On this study, we applied nonnegative matrix factorization (NMF), an unsupervised learning algorithm, to CO-less $H_2^{15}O-PET$ to investigate coronary endothelial dysfunction caused by smoking noninvasively. Materials and methods: This study enrolled eighteen young male volunteers consisting of 9 smokers $(23.8{\pm}1.1\;yr;\;6.5{\pm}2.5$ pack-years) and 9 nonsmokers $(23.8{\pm}2.9 yr)$. They do not have any cardiovascular risk factor or disease history. Myocardial $H_2^{15}O-PET$ was performed at rest, during cold ($5^{\circ}C$) pressor stimulation and during adenosine infusion. Left ventricular blood pool and myocardium were segmented on dynamic PET data by NMF method. Myocardial blood flow (MBF) was calculated from input and tissue functions by a single compartmental model with correction of partial volume and spillover effects. Results: There were no significant difference in resting MBF between the two groups (Smokers: 1.43 0.41 ml/g/min and non-smokers: $1.37{\pm}0.41$ ml/g/min p=NS). during cold pressor stimulation, MBF in smokers was significantly lower than 4hat in non-smokers ($1.25{\pm}0.34$ ml/g/min vs $1.59{\pm}0.29$ ml/gmin; p=0.019). The difference in the ratio of cold pressor MBF to resting MBF between the two groups was also significant (p=0.024; $90{\pm}24%$ in smokers and $122{\pm}28%$ in non-smokers.). During adenosine infusion, however, hyperemic MBF did not differ significantly between smokers and non-smokers ($5.81{\pm}1.99$ ml/g/min vs $5.11{\pm}1.31$ ml/g/min ; p=NS). Conclusion: in smokers, MBF during cold pressor stimulation was significantly lower compared wi4h nonsmokers, reflecting smoking-Induced endothelial dysfunction. However, there was no significant difference in MBF during adenosine-induced hyperemia between the two groups.

Objectives: This study Development of a healthy college life, and effective for smoking cessation programs for education is to utilize as a basis for. Methods: The study employs frequency analysis, cross-analysis and correlation analysis through SPSS Win 17.0 on 296 (84.6% of total participants) from the entire participants of 350. The significance test is delivered with ${\chi}^2$-test. Results: 1) The participants consist of 47.7% (147) males and 52.3% (161) females. 78.2% (241) has experience of smoking cessation program at high school. 61.7% (190) has parents who are smoking. 40.9% (126) answers that they are currently smoking while 59.1% (182) answers that they are not. 2) When asked about their perception on quitting smoking, 81.2% (250) says that non-smokers are distressed by others' smoking. 74.0% (228) has unpleasant experience with cigarette smoke. 3) The analysis of the relation between smoking cessation program at high school and smoking shows that 63.8% of the ones who have experience of the program are non-smokers while 68.7% of those with no experience of the program are smokers. 4) Among those who have tried to quit smoking, 73.9% have experience of smoking cessation program at high school. 31.8% of these participants also reveal their interest in the cessation program. 5) In the analysis of the correlation between smoking habits, the experience of smoking cessation program at high school is closely related to non-smoking while current smoking habit is highly related to the strong interest in participation of cessation program. Also, the more interest they have in participating, the stronger needs they feel for smoking prevention program at college. Conclusion: Therefore, the last phase of education-related courses at the University of educated and credits granted through open non-smoking pledge, non-smoking club, non-smoking camps, training programs, such as smoking in non-smoking education and programs for students interested in openness and participation must be done will.

Background: This study aimed to explore potential associations between single nucleotide polymorphisms (SNPs) of the x-ray repair cross-complementing group 1 (XRCC1) and cleft lip and palate transmembrane protein 1-like (CLPTM1L) and non-small cell lung cancer (NSCLC) susceptibility in non-smoker Chinese patients. Methods: A total of 200 NSCLC patients and 200 healthy controls with matched age and gender were recruited for genotyping of XRCC1 SNPs (rs2256507 and rs1001581) and CLPTM1L SNPs (rs401681 and rs4975616). Association of these SNPs with NSCLC risk was evaluated by computing the odds ratio (OR) and 95% confidence interval (CI) from multivariate unconditional logistic regression analyses with adjustment for gender and age. Results: The frequencies of genotype and allele in these four loci (rs2256507, rs1001581, rs401681, and rs4975616) were not significantly different between the cases and controls, or between either of the histological subgroups (adenocarcinoma and squamous cell carcinoma) and controls. Conclusions: Although these SNPs are associated with NSCLC risk in patients with a tobacco-smoking habit, this study demonstrated that XRCC1 and CLPTM1L gene SPNs are not linked with NSCLC risk in non-smoking patients, indicating that molecular mechanisms of NSCLC betwee tobacco smokers and non-smokers may be different. Future studies are needed to uncover the underlying molecular mechanisms for NSCLC in non-smokers.

This study was conducted to determine the urinary nicotine and cotinine concentration in 126 smokers and 143 nonsmokers. While urine samples were being collected, personal characteristics related to smoking habit such as sex, age, number of years since a person has been a smoker, average number of cigarettes consumed per day, and number of smokers in the family were surveyed. Urinary nicotine and cotinine concentration were analyzed by GC/NPD. The smokers smoked an average 17.0 cigarettes per day and the average concentration of nicotine and cotinine was 3.88 $\mu\textrm{g}$/ml and 3.64 $\mu\textrm{g}$/ml, respectively. The average number of smokers in the family was 0.72 persons and the average concentration of nicotine and cotinine were 0.11 $\mu\textrm{g}$/ml and 0.02 $\mu\textrm{g}$/ml in the urine of non-smokers, respectively. The concentration of nicotine and cotnine in smoker\`s urine was dependent on the number of cigarettes smoked per day(p<0.01). The number of years since a person had been a smoker, and the number of smokers in the family were not associated with the concentration of nicotine and cotinine. Also there was no significant effects of passive smoking on the family of smokers by the level of nicotine and cotinine concentration. We describe the relationship between smoking habit as assessed by urinary nicotine and cotinine excretion. This study provides an evidence for the assessment of active and passive exposure to tobacco smoke.

Background: Tobacco use is a leading cause of preventable morbidity and mortality from non-communicable diseases. The objectives of the study were to determine the percentage of annual income used to purchase tobacco-related products and treat tobacco-related illnesses, and assess the characteristics of smokers and their awareness of the health-related risks of smoking. Method: Stratified and snowball sampling methods were used to obtain information (via a 17-item, close-ended questionnaire) from 85 adult respondents (49 males and 36 females). The instrument comprised of demographic characteristics, smoking behavioural/lifestyle, health, and micro socio-economics. Results: There were no significant differences between individuals who were affected by chronic obstructive pulmonary disorder (COPD) (14.1%) and cardiovascular disease (18.8%). It was found that respondents spend 30-39% of their annual income on tobacco-related products. Forty percent (40.0%) and 41.7% of respondents with lung cancer and COPD respectively spend more than 50% of their annual income to treat these diseases. The majority (80%) of those who continues to consume tobacco-related products were uncertain as to why they were doing it. Not all the smokers were aware of the dangers of tobacco consumption despite their level of education. Conclusion: The majority of the respondents who had tobacco-related illnesses such as lung cancer and COPD spend a significant amount of their income on their health care. Not all the smokers were aware of the dangers of tobacco consumption despite their level of education. This suggests the need for increase public awareness where both smokers and non smokers are being fully or adequately informed about the dangers or health risks of tobacco consumption.

Graphic health warnings (GHW) on tobacco packages have proven to be effective in increasing quit attempts among smokers and reducing initial smoking among adolescents. This research aimed to examine the relative importance of different attributes of graphic health warnings on tobacco packages in Viet Nam. A discrete choice experimental (DCE) design was applied with a conditional logit model. In addition, a ranking method was used to list from the least to the most dreadful GHW labels. With the results from DCE model, graphic type was shown to be the most important attribute, followed by cost and coverage area of GHW. The least important attribute was position of the GHW. Among 5 graphic types (internal lung cancer image, external damaged teeth, abstract image, human suffering image and text), the image of lung cancer was found to have the strongest influence on both smokers and non-smokers. With ranking method, the image of throat cancer and heart diseases were considered the most dreadful images. GHWs should be designed with these attributes in mind, to maximise influence on purchase among both smokers and non-smokers.

Objectives : This research examined the Patient Hygiene Performance(PHP) index according to smoking and tooth brushing behavior, in order to analyze how they influence the oral hygiene. Methods : This research used PHP index and the structured questionnaire. The subjects were 203 men in their 20's who visited K university's dental hygiene department for oral prophylaxis from March to July of 2012. For data analysis SPSS WIN 12.0 was used. Results : 1. The average PHP index of all experimented subjects was 2.66, a very poor level. The PHP index according to general characteristics, smoking, drinking, and exercise showed statistical significance(p<0.05). 2. PHP index decreased with more frequencies and longer durations of toothbrushing(p<0.05). 3. The PHP index of smokers is higher than that of non-smokers. In the case of non-smokers, the frequency, method, and duration of tooth brushing had a statistical significance(p<0.05). 4. The PHP index of smokers who smoke less than or equal to ten cigarettes is 2.53 and smokers who smoked more than 10 cigarettes is 3.10. 5. The results of multiple regression analysis showed that smoking increased the PHP index, while the increase in tooth brushing frequency and the up and down tooth brushing method decreased the PHP index. All the coefficients were statistically significant (p<0.05). Conclusions : In order to increase Patient Hygiene Performance(PHP) index. there must be a decrease in smoking rate while people increase their tooth brushing frequency and use a proper tooth brushing method.

The purpose of this study was to compare the life satisfaction of smokers and non - smokers among rural elderly people and to provide a balanced understanding of smoking rather than prejudice about smoking. To do this, we selected 10 S-eup sites as a sample and conducted a life satisfaction survey of 100 smokers and 100 nonsmokers among the elderly aged 65 years and over, and compared the differences in psychological life satisfaction among these groups. The results showed that smokers were significantly more satisfied with mental life satisfaction, enjoyment of life, participation in social activities and loneliness than non - smokers. These results suggest that elderly people aged 65 and over in rural areas are exposed to smoking habits for at least 3,40 years. The results of this study are expected to help the elderly living in aging society to understand the cigarette smokes correctly. In the future study, Research is expected to be active.
