Comprehensive bans on tobacco advertising and promotion were introduced through tobacco control legislation in Viet Nam, but it has been established that violations of the bans are very common. This study was conducted to explore the trend in violations of bans on tobacco advertising and promotion at points of sale in Viet Nam in the past six years and to explore any differences in the violation situations before and after the Law on Tobacco Control came into effect on 1st May 2013. Quantitative data were collected through observation of violations of the bans on tobacco advertising and promotion at points of sale in 10 provinces throughout Viet Nam in four survey rounds (2009, 2010, 2011, and 2015). Variation in violation prevalence over time was examined by chi-square test using a Bonferini method. Binary logistic regression was employed to identify the factors that may have influences on different types of violation. A level of significance of p<0.05 was used for all tests in this article. The most common form of violation was the display of more than one pack/one carton of a cigarette brand. Violation of bans on tobacco advertising increased while violations on promotion ban and on displaying tobacco decreased through time. Some factors associated with the tobacco advertising and promotion bans included surveyed years, types of points of sale, regions and areas where the points of sale were located. The enforcement of the bans did not improve even after the issuance and the enactment of the Law on Tobacco Control. This suggests that the monitoring and enforcement of bans on tobacco advertising and promotion at points of sale should be strengthened. Penalties should be strictly applied for violators as indicated in the current tobacco control legislation.

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.

Background: Tobacco use among youth is a major public health problem. Youth outside of formal school settings are often understudied but may be at increased risk. Materials and Methods: A descriptive cross-sectional study was carried out among 326 young people aged 15-24 years in four randomly selected motor parks in Lagos state. Interviewer-administered questionnaires were used to collect data. Results: The mean age of the respondents was $21.0{\pm}2.3yrs$. Many 252 (77.3%) dropped out before the end of the third year of secondary schooling. The majority were aware that active (78.2%), and passive smoking (77.3%) are harmful to health. Nearly two-thirds of the respondents disagreed with an outright ban of cigarettes (63.2%) and restriction of cigarette sales to persons below 18 years (67.9%) while 254 (66.8%) supported a ban on tobacco smoking in enclosed public places. One hundred and fifty (46.0%) respondents had experimented with smoking of which 106 (32.5%) had progressed to become current smokers. Half of the current smokers, 54 (50.9%), felt the need for a cigarette first thing in the morning. A multivariate analysis for smoking initiation, showed that for every increasing year of age, respondents were 1.08 times more likely to have initiated cigarette smoking; males and respondents who lived alone or with peers were 2.34 times and 1.77 times more likely to have initiated smoking respectively; those who consume alcohol and marijuana were 7.27 and 1.89 times respectively more likely to have initiated smoking while those who consumed alcohol were 6.17 times more likely to be current smokers.

황색종 잎담배의 성숙과 노쇠 (이식후 50일부터 106일까지 )에 따른 생엽중 전분, 전당, 니코틴 및 전질소의 함량 변화와 이들 성분간의 관계를 조사한바, 전분함량은 두 품종 모두 각 엽위에서 성숙함에 따라 증가하였으나 노쇠함에 따라 감소하였다. 전질소 함량은 성숙함에 따라 감소하였으나 니코틴 함량 은 점점 증가하였다. 전당 함량은 성숙함에 따라 감소하는 경향이었다. 전분 함량은 전질소 함량과는 부의 상관을 보였으나 니코틴 함량과는 정의 상관이 인정되었다. 전질소 함량과 니코틴 함량은 부의 상관이 인정되었다. 그러므로 수확기를 관행보다 5-7일 늦추는 것은 건엽에서 환원당과 니코틴의 비를 더 좋게 하는 방법일 것이다.

In this study quality of tobacco cessation information provided through Internet web sites was evaluated in terms of retrievability, easy of use, user-supportiveness, feedback, and continuity. This study limited to those internet web sites developed and delivered by Korean public health service organizations or their related institutions or associations. This study analyzed 8 internet web sites and evaluation criteria developed by Chung, Yong Chul (2002) and Yoo, Sarah (2001) were used. Study results indicated that retrievability was evaluated low except search-speed of data: the easy of use was evaluated moderately: user-supportiveness was evaluated moderately: feedback, and continuity of those sites were evaluated low. The quality of tobacco cession information of those sites are needed to be improved. The development of guidelines for standardized health information on Internet web sites is necessary, too.

본시험은 붕소시용이 잎담배의 생리적특성과 입고병 발생에 미치는 영향을 구명하고자 황색종인 NC2326, Coker 86을 공시하여 입고병포장에서 실시한바 그 결과를 요약하면 다음과 같다. 1. 붕소시용량이 증가할수록 지상부의 생장이 지연되었고 간장은 낮아졌으나 붕우시용구에서 세근발달이 억제되고 뿌리의 부패율과 입고병이병율이 크게 감소 되여 입고병발생에 간접적인 효과가 있었다. 2. 수량은 10a당 붕소 또는 붕산 $2\~4kg$ 시용구에서 높았고 붕소시용에 따른 증수경향은 NC2326에서 컸다. 3. 건엽중의 Phenol 화합물은 붕소시용구에서 증가하였고 입고병저항성이 큰 Coker 86에서 더 많았으며 니코친합량은 붕소시용량이 증가할수록 감소하였다.

Background: In 2013, legislation in Vietnam regulated smoking in public areas. Included was a ban on indoor smoking at universities. Objective: Since awareness and attitude are moderators of the effectiveness of smoke-free policy, ou aim was to assess changes in students' knowledge and attitude tosecond hand smoke (SHS) and awareness and support of smoke-free legislation at four Vietnamese universities, one year after legislative changes. Methods: A two-phase cross sectional study of undergraduate students using self-administered questionnaires (based on the Global Adult Tobacco Survey and the Thrasher survey) was conducted at the introduction of the legislation and one year thereafter. Results: One-year post legislation there were significant increases in knowledge of smoke-free legislation and awareness of universities as smoke-free environments. There was a significant increase in knowledge of harmful effects of SHS on diseases such as examples in the heart and lung, including lung cancer, and miscarriage. Students expressed strong support of smoke-free environments in universities, hospitals, schools, workplaces, public transport, libraries, cinemas and theatres; support was also increased post legislation. Changes were seen in attitude to SHS, and rights of non-smokers and smokers. Conclusions: Positive changes have occurred in knowledge and attitude toward smoke-free environments and SHS in universities since enactment of Vietnamese tobacco control legislation.
