Objectives: This pilot study assessed secondhand smoke (SHS) exposure in smoking and non-smoking nightclubs in Seoul, Korea by measuring the concentration of particulate matter smaller than $2.5{\mu}m$ ($PM_{2.5}$). Methods: This comparative study was conducted in three nightclubs in Seoul. While one non-smoking nightclub was measured on weekdays and weekends, different smoking nightclubs were measured on weekdays and weekends. The concentration of $PM_{2.5}$ was observed using a real-time monitor over an average of three hours. The number of people in the clubs was also estimated. Settled dust was collected in a smoking and a non-smoking nightclub and analyzed for NNK concentration. Results: The $PM_{2.5}$ concentration in the smoking nightclubs was higher than those found in the non-smoking nightclub by 26 times on weekdays and three times on weekends. Indoor $PM_{2.5}$ concentration was correlated with the number of people in the smoking nightclubs. Relatively high $PM_{2.5}$ concentration was observed in the non-smoking nightclub on weekends. NNK concentration in the smoking nightclub was 7 times higer than in the non-smoking nightclub. Conclusion: Smoking in nightclubs caused high $PM_{2.5}$ concentration. Although the non-smoking nightclub had a lower $PM_{2.5}$ concentration, $PM_{2.5}$ concentration on weekends was higher due to the smoking room. Complete prohibition of smoking in nightclubs can protect patrons from secondhand smoke exposure.

Objectives: The purpose of this study was to investigate the effect of a child-parent secondhand smoke(SHS) prevention program(C-PSHSPP). Methods: The participants were parents whose children were attending daycare centers located in S city. The institutions were selected using two-stage cluster sampling and data were collected using a structured questionnaire. Descriptive statistics were performed using SPSS version 18.0. Results: Number of cigarettes smoked per day, rate of smoking when with child decreased significantly. Parental awareness on SHS and scores on changes of experiential process increased significantly. Conclusions: From these results, it is suggested that the C-PSHSPP has beneficial effects in decreasing parental daily smoking amount at the same time increasing parental awareness on SHS and importance of smoking cessation. Therefore, C-PSHSPP can be recommended as a SHS intervention program for preschool children.

Objectives: This study examined the extent to which attitudes about smoke-free air policies (SFAPs) in bars/restaurants, workplaces, all public places, and motor vehicles when minors are present can be explained by individuals' sociodemographic characteristics, smoking status, and beliefs about the health of others. Methods: Data were gathered from 359 individuals age 18 or older who attended the Lawrence County Fair in Indiana, United States, in July, 2009, an area where there were no SFAPs in place at the time of survey administration. Results: Multinomial logistic regression analyses indicated that perceived severity of secondhand smoke (SHS) on others, perceived responsibility of smokers for the harm their SHS causes to others, and perceived susceptibility of others to SHS exposure, along with education level and smoking status, significantly predict opposition to SFAPs in this population. Conclusions: The results of this exploratory study suggest the need for additional research related to attitudes about health policies as well as to the practical applications of these findings for smoke-free air advocacy.

Objectives: Although the Korean government is able to implement smoke-free regulations for shared areas in multi-unit housing (MUH), such regulations are limited for private homes. The purpose of this study was to determine the prevalence and predictors of support for the implementation of smoke-free regulations for homes and near the outsides of building among residents in MUH. Methods: A population-based sample of 2,600 residents among a web-based panel in Seoul was included. The residents completed questionnaires including smoking status, voluntary smoke-free home rules, and support for the implementation of smoke-free regulations for homes and near the outsides of building. The presence of a voluntary smoke-free home rule was determined when residents declared that no one smoked inside their homes. Results: Among the 2,600 MUH residents, prevalence of support for the implementation of smoke-free regulations for homes was higher (83.2%) than for near the outsides of buildings (75.1%). Support for the implementation of smoke-free regulations for homes was higher when residents were non-smokers, had voluntary smoke-free home rules, lived with children, lived with more residents, lived in owned homes, lived in apartments, and lived in homes with more frequent secondhand smoke (SHS) incursion. Support for the implementation of smoke-free regulations near the outsides of buildings was higher when residents were women, non-smokers, more educated, had a voluntary smoke-free home rule, lived with children, lived in homes with more frequent SHS incursion, and lived in a commercial area. Conclusions: The majority was supportive of the implementation of smoke-free regulations for homes. Predictors identified in the study can be useful for promoting implementation of smoke-free regulations for homes in MUH.

Purpose: The purpose of this study was to identify the assertive behavior of asking smokers not to smoke and investigate the factors related to assertive behavior in patients with vascular diseases. Methods: Participants were 203 adult Korean patients with vascular diseases such as cerebral infarction and myocardial infarction. Data were collected using questionnaires that included the characteristics of secondhand smoke (SHS), secondhand smoke-related variables (Health belief model factors, health promotion model factors) and level of assertive behavior. Descriptive statistics, t-test, ANOVA and multiple regression using SPSS/WIN 18.0 were performed. Results: Participants who never ask smokers not to smoke was 39.9%, whereas participants who always ask was 7.4%. There was a weak positive relationship between assertive behavior and susceptibility to disease (r=.18), severity of disease (r=.19), benefit of assertive behavior to SHS exposure (r=.10), barrier of assertive behavior to SHS exposure (r=.24), and self-rated health (r=.21) respectively. There was a moderate positive relationship between assertive behavior and self-efficacy of assertive behavior to SHS exposure (r=.49). Health belief model factors explained 15.7% variance and health promotion model factors explained 27.0% of assertive behavior. Conclusion: The findings of this study suggest that self-efficacy of assertive behavior to SHS exposure is a very important factor. Therefore the development of a program to foster self-efficacy of assertive behavior regarding SHS exposure in patients with vascular diseases is needed.

Because of space constraints of the ship, accessibility to supporting system for nonsmoking is poor in seafarers' group. This study was performed to find the smoking status, second-hand smoking status and factors related to smoking habit of Korean seafarers. So, we examined the rate of smoking and secondhand smoking, and knowledge about smoking, attitude for smoking behavior, smoking cessation intention and working environment related to smoking of 155 seafarers. Their smoking rate was 32.3% and secondhand smoke rate was very high by 86.5%. Their working place equipped a separate smoking room, but most of them had been smoked in where they were stayed. and we found the inadequate ventilation facility in 42.6%. Only 21.9% had a experience of education for smoking cessation. From the study Attitude for smoking behavior was negative and smoking knowledge was high. 90% of them tried to stop to smoke, but intention of smoking cessation was low. We need to motivate seafarers and increase their smoking cessation intention by regular education in available ways. From the study, we purpose that government will realign regulations related to ventilation facility and appointed smoking area on the board to prevent seondhand smoke, and the policy need to possess the regular survey of smoking status and customized smoking cessation education for seafarers.

Purpose:The present study was to apply the Attitudes-Social influence-Efficacy (ASE) model in order to identify factors associated with the assertive behavior of non-smoking college students when they are exposed to secondhand smokes in Korea. Methods: Data were collected from non-smoking college students (N=1,656, 76.6% female) at two universities in Seoul and Gyeonggi-do. The main outcome measure was the assertive behavior. ASE factors such as attitudes toward being assertive, social influences, and self-efficacy as well as socio-demographic, health-related, and smoking-related factors were self-administrated. Results: The mean of the assertive behavior (range 1~5 points) was 2.23;37.6% was not at all assertive, while 4.3% was always assertive. Higher assertiveness was significantly correlated with a higher level of positive attitude, social influence and self-efficacy (p<.05 for all). Stepwise multiple regression analyses showed that the social influence was the strongest factor associated with the assertive behavior (${\beta}=0.430$, p<.001, $R^2$=.246), followed by self-efficacy, motive to assertiveness, having any family member who had diseases, and male gender. These factors explained the assertive behavior by 39.7%. Conclusion: The ASE model may explain the assertive behavior of non-smoking college students under secondhand smoke exposure. Social influence and self-efficacy were significant factors associated with their assertive behavior.

Objectives: Outdoor tobacco smoke can penetrate into the indoor environment through cracks in the building envelope. This study aimed to characterize the particle size distribution of infiltrated secondhand smoke (SHS) through the gap in a single glazed and a secondary glazed window according to pressure differences in a chamber. Methods: Two polyvinyl chloride sliding windows were evaluated for infiltration, one with a glazed window and the other with a secondary glazed window. Each window was mounted and sealed in a polycarbonate chamber. The air in the chamber was discharged to the outside to establish pressure differences in the chamber (${\Delta}P$). Outdoor smoking sources were simulated at a one-meter distance from the window side of the chamber. The particle size distribution of the infiltrated SHS was measured in the chamber using a portable aerosol spectrometer. The particle size distribution of SHS inside the chamber was normalized by the outdoor peak for fine particles. Results: The particle size distribution of SHS inside the chamber was similar regardless of window type and ${\Delta}P$. It peaked at $0.2-0.3{\mu}m$. Increases in particulate matter (PM) concentrations from SHS infiltration were higher with the glazed window than with the secondary glazed window. PM concentrations of less than $1{\mu}m$ increased as ${\Delta}P$ was increased inside the chamber. Conclusions: The majority of infiltrated SHS particles through window gap was $0.2-0.3{\mu}m$ in size. Outdoor SHS particles infiltrated more with a glazed window than with a secondary glazed window. Particle sizes of less than $1{\mu}m$ were associated with ${\Delta}P$. These findings can be a reference for further research on the measurement of infiltrated SHS in buildings.

Objectives: We examined the prevalence of tobacco use and exposure to secondhand smoke among middle-school students in Korea using the Global Youth Tobacco Survey (GYTS) in 2013. Methods: The GYTS in Korea was conducted between July and August 2013 by the Korea Centers for Disease Control and Prevention. Data were collected using a self-administered anonymous questionnaire from a nationally representative sample of middle-school students aged 13-15 years in sampled classrooms. Results: The GYTS in Korea was completed by 4235 students aged 13-15 years in 43 middle schools. Approximately one in five of the students (17.8%) reported that they had tried cigarettes in the past, while 5.2% reported currently being cigarette smokers. Current cigarette smoking was higher in boys (7.5%) than in girls (2.6%). Of the students, 29.7% had been exposed to secondhand smoke at home, 47.4% inside enclosed public places, and 53.9% in outdoor public places. Of the current cigarette smokers, 25.7% bought their cigarettes from a store despite a law prohibiting this. Additionally, 58.0% of students noticed point-of-sale tobacco advertisements or promotions, 66.8% of current cigarette smokers wanted to stop smoking, and 70.9% of students had been taught about the dangers of tobacco use in school. Conclusions: These findings provide an opportunity to develop, implement, and evaluate a comprehensive tobacco control policy. The results suggest that youth have relatively easy access to cigarettes and are regularly exposed to secondhand smoke in public places, as well as to point-of-sale tobacco advertisements and promotions. Strict enforcement of the ban on tobacco sales to youth, expanding smoke-free areas, and advertising bans are needed to reduce tobacco use among youth.

Objectives: The purpose of this study is to investigate the factors that affect the smoking type among those who have used regular cigarettes, liquid or cigarette-type e-cigarettes. Methods: The subjects of analysis were 6,081 people who had smoked regular cigarettes or e-cigarettes. For data analysis, SPSS ver.25.0 statistical package program was used. Multinomial logistic regression analysis was performed to find out the factors affecting smoking type. Results: Factors affecting the experience of using e-cigarettes compared to regular cigarette smoking are gender and class. Academic performance, living with family members, drinking experience, and secondhand smoke in school. The factors influencing dual use compared to regular cigarette smoking were gender, class, academic performance, economic status, living with family, drinking experience, and experience of secondhand smoke in school. Smoking cessation attempts had an effect on dual use compared to regular cigarette smoking. Conclusion: Smoking cessation experience had a greater effect on e-cigarette use than regular cigarette smoking.
