  • Cigarette smoking is known to be associated with various chronic pulmonary and cardiovascular diseases ranging from inflammation to cancer. Not only first-hand smoke but also second-hand smoke is suggested to be a factor of health risk. This study was to investigate whether Platycodi Radix extract administration would alter oxidative stress in lung leading to protection of cigarette smoke-induced lung damage. Sprague-Dawley rats were randomly divided into 3 groups; Intact, Smoke+PR and Smoke+Vehicle. In Smoke+PR and Smoke+Vehicle group, the exposure to cigarette smoke was performed for 15 min/day for 4 weeks in ventilated smoking chamber. The Platycodi Radix extract and saline were orally administrated to Smoke+PR and Smoke+Vehicle group each. The rats of Intact group were just kept in ventilated chamber without cigarette smoke. After the experiment for 4 weeks, the lung tissues were collected for histological observation and immunohistochemistry. In Results, airspace enlargement and goblet cell hyperplasia were observed after 4 weeks' exposure to cigarette smoke. Whereas, the oral administration of Platycodi Radix extract for 4 weeks reduced airspace enlargement and goblet cell hyperplasia. Moreover, the alterations of BAX/Bcl-2 proteins in lung tissues were observed. These results suggest that Platycodi Radix extract ameliorates lung damage in cigarette smoke-exposed rats and has protective effects on second-hand smoke injury.

  • Background: This study was performed to gather data on second-hand smoke (SHS) concentrations in a range of public venues following the implementation of partial Smoke-Free Legislation in Malaysia in 2004. Materials and Methods: $PM_{2.5}$ was measured as a marker of SHS levels in a total of 61 restaurants, entertainment centres, internet caf$\acute{e}$s and pubs in Kuala Lumpur, Malaysia. Results: Under the current smoke-free laws smoking was prohibited in 42 of the 61 premises. Active smoking was observed in nearly one-third (n=12) of these. For premises where smoking was prohibited and no active smoking observed, the mean (standard deviation) indoor $PM_{2.5}$ concentration was 33.4 (23.8) ${\mu}g/m^3$ compared to 187.1 (135.1) ${\mu}g/m^3$ in premises where smoking was observed The highest mean $PM_{2.5}$ was observed in pubs [361.5 (199.3) ${\mu}g/m^3$]. Conclusions: This study provides evidence of high levels of SHS across a range of hospitality venues, including about one-third of those where smoking is prohibited, despite 8 years of smoke-free legislation. Compliance with the legislation appeared to be particularly poor in entertainment centres and internet caf$\acute{e}$s. Workers and non-smoking patrons continue to be exposed to high concentrations of SHS within the hospitality industry in Malaysia and there is an urgent need for increased enforcement of existing legislation and consideration of more comprehensive laws to protect health.

  • Second-hand tobacco smoke (SHS) exposure at home, especially among children, is a serious issue in Viet Nam. During the past decade, much effort has been taken for tobacco control in the country, including various prgorammes aiming to reduce SHS exposure among adults and children. This article analysed trends and factors associated with SHS exposure at home among school children aged 13-15 in Viet Nam, using the Global Youth Tobacco Surveys conducted in 2007 and 2014. Descriptive and inferential statistical methods with logistic regression were applied. Overall, there was a significant reduction in the level of exposure, from 58.5% (95%CI: 57.6-59.3) in 2007 to 47.1% (95%CI: 45.4-48.8) in 2014. Of the associated factors, having one or both parents smoking was significantly associated with the highest odds of SHS exposure at home (OR=5.0; 95%CI: 4.2-6.1). Conversely, having a mother with a college or higher education level was found to be a protective factor (OR=0.5; 95%CI: 0.3-0.8).

  • Through various media, damage of both smoking and second-hand smoking has been recognized, and brought global scale of interest in antismoking. In Korea, government has tightened regulations of smoking in non-smoking zone since December, 1980, and after National Health Promotion Act in 1995, non-smoking zone has been gradually expanded. On the other hand, there were law suits to find those regulation towards smokers are either unconstitutional or not for 4 times. In this current state, people need smoking area to prevent second-hand smoking and to consider smokers in multi-unit dwelling. Main purpose of this research is to plan smoking spaces based on various typology of multi-dwelling plan for protection of both smokers and non-smokers' right. The research group collected and analyzed the smoking behaviors in various multi-unit dwelling types such as flat type, tower type, hybrid type and others. Based on those data, the group found three phenomena. First, there are internal regulations in multi-unit dwelling to make non-smoking zone based on National Health Promotion Act and resident representative meeting decision. Second, main smoking activities are occurring at major traffic line and entrances. Third, smoking inside of multi-unit dwelling complex causes second-hand smoking to residents live in $1^{st}$ floor and when they enter. Therefore, one can achieve both smokers' and non-smokers' protection of right by creating a designated smoking space near main entrances of multi-unit dwelling complex to consider smokers' and prevents second-hand smoking by using shaft space, which is in core space, to ventilate tobacco smoke through roof.

  • Tobacco use is the most important preventable risk factor for premature death. The World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC), the first international public health treaty, came into force in 2005. This paper reviews the present status of tobacco control policies in Korea according to the WHO FCTC recommendations. In Korea, cigarette use is high among adult males (48.2% in 2010), and cigarette prices are the lowest among the Organization for Economic Cooperation and Development countries with no tax increases since 2004. Smoke-free policies have shown incremental progress since 1995, but smoking is still permitted in many indoor public places. More than 30% of non-smoking adults and adolescents are exposed to second-hand smoke. Public education on the harmful effects of tobacco is currently insufficient and the current policies have not been adequately evaluated. There is no comprehensive ban on tobacco advertising, promotion, or sponsorship in Korea. Cigarette packages have text health warnings on only 30% of the main packaging area, and misleading terms such as "mild" and "light" are permitted. There are nationwide smoking cessation clinics and a Quitline service, but cessation services are not covered by public insurance schemes and there are no national treatment guidelines. The sale of tobacco to minors is prohibited by law, but is poorly enforced. The socioeconomic inequality of smoking prevalence has widened, although the government considers inequality reduction to be a national goal. The tobacco control policies in Korea have faltered recently and priority should be given to the development of comprehensive tobacco control policies.

  • Objectives: This study examined the impact of a smoke-free policy on indoor air quality at indoor recreation facilities by assessing $PM_{2.5}$ concentrations before and after the implementation of the new policy. Methods: Using real-time monitors, $PM_{2.5}$ concentrations were measured in 50 billiard rooms and 50 golf simulator rooms in Seoul, Korea. The characteristics of the indoor recreation facilities, smoking status, and atmospheric conditions were recorded at the same time.After the enforcement of a smoke-free policy, $PM_{2.5}$ concentrations, installation of smoking room, and smoking status were examined when the facilities were revisited. Results: Almost a half of the billiard rooms and over 80% of golf simulator rooms were located underground. Seventy percent of the billiard rooms and one hundred percent of the golf simulator rooms were equipped with a local exhaust ventilation system. After the implementation of the smoke-free policy, 46% of the billiard rooms and 20% of the golf simulator rooms newly installed a smoking room. In the billiard rooms with a newly-installed smoking room, the $PM_{2.5}$ concentrations decreased from 97.9 to $45.6{\mu}g/m^3$ after the implementation of the smoke-free policy. The same change of 29.0 to $ 26.3{\mu}g/m^3$ was not statistically significant in golf simulator rooms. Indoor $PM_{2.5}$ concentrations were correlated with outdoor $PM_{2.5}$ concentrations, number of smokers, and number of people in the room. Conclusions: The smoke-free policy for indoor recreation facilities was not effective at making the indoor spaces free from second hand smoke. Although a few billiard rooms installed a smoking room, indoor $PM_{2.5}$ concentrations were still higher than those of outdoor $PM_{2.5}$ or atmospheric $PM_{2.5}$. Stricter enforcement of the smoke-free policy should be achieved to prevent secondhand smoke exposure.

  • 육지와 떨어진 제약적 환경 때문에 선박에서 근무하는 해기사는 사무직근로자보다 보건소와 같은 금연지원체계에 대한 접근성이 떨어질 수 있다. 본 연구는 한국 해기사의 흡연 및 간접흡연 실태를 파악하고 관련요인을 조사하기 위해 총 155명의 대상자에게 홉연 및 간접흡연 경험, 흡연에 대한 지식, 태도 및 금연의도와 선박 내 흡연시설에 대해 설문하였다. 조사 결과, 대상자의 흡연율은 32.3%였고, 간접흡연율은 86.5%로 높은 수준이었다. 선박 내 금연구역이 있는 경우에도 대부분의 흡연행위가 휴게실과 같은 해기사들의 생활 공간에서 주로 발생한다고 답하였다. 또한 선박 내 지정흡연실이 없거나 환풍시설이 미비한 경우도 40%정도에 이르는 것으로 조사되었다. 한편, 대상자 중 금연교육을 받은 사람은 21.9%에 불과하였다. 흡연행위에 대한 태도는 34.58점(총 60점)으로 부정적이었고, 흡연에 대한 지식은 16.12점(총 20점)으로 중간보다 높았다. 흡연자 10명 중 9명은 금연을 시도한 경험이 있었으나 금연 의도는 낮은 것으로 나타났다. 제한된 공간에서 근무와 생활을 병행하는 장기간 체류하는 해기사들의 흡연율을 감소시키기 위해서는, 해기사가 활용 가능한 방법으로 주기적인 금연교육을 통해 동기를 부여하고 금연의도를 높일 필요가 있다. 또한 정기적으로 흡연 실태조사를 조사하여 간접흡연의 피해를 주기적으로 파악하는 한편, 선박 내 흡연관련시설 등 환경적 요인에 대한 법규를 재정비하는 등 제도적 정비가 필요하다.
