Purpose: Factors associated with ever-use and differences between ever-users and non-users of tobacco among adolescent school students from low income families in Mumbai were assessed. Materials and Methods: A self-administered questionnaire, completed by 1918 students from grades 7, 8 and 9 in 12 schools managed by the city municipal corporation in July 2015, gathered data on socio-demographic characteristics, tobacco use and tobacco-related knowledge, attitudes and beliefs. Results: Although only 1% of respondents thought tobacco was cool, nearly 35% were unaware of associations between tobacco use and health problems. Male students were almost twice as likely (OR=2.5, P <= 0.05) to have ever used tobacco compared to females and Supari (areca nut) users were eight times more likely (OR=8.99, P < 0.001) than Supari non -users. Tobacco-users were more likely to agree with statements: 'People who use tobacco have more friends' (OR=2.8, P = 0.004), 'Smoking relieves stress' (OR=5.6, P = 0.002) and 'It is possible to purchase any tobacco product within 100 yards of school' (OR=10.8, P < 0.001). Conclusion: This study highlights the gains made by tobacco prevention campaigns in that almost all students did not consider tobacco as cool or a stress reliever. However, they still need education about health consequences of tobacco-use. In addition, Supari use has to be addressed in school-based tobacco prevention and cessation initiatives. Furthermore, programs must also address perceptions and norms related to peers and tobacco use and ensure active implementation of existing laws. Such integrated measures will help ensure tobacco-free spaces around schools.

Using sucker agents for tobacco can lead some advantages including saving labor, increasing yield and reducing the spread of diseases. At present, the sucker control agents used in China mainly depended on importing. The agents includes two groups, systemics (Maleic hydrazide: MH, etc) and partial systemics (Butralin, Flumetralin, Pendimethalin, etc). Now, Pendimethalin(a.i. 33%, wp) was used extensively all over the tobacco field in China. Sucker control agents will also be used for tobacco production in China. Because of the high price of the imported agents, China has studied on the domestic production of tobacco sucker control agents and has made some progresses.

In this study we analyse how the tobacco prices have an effect on the national health. The level of tobacco price will fluctuate its consumers demand and eventually affect the national health status. We estimate tobacco consumption function as well as households'demand system in which tobacco and health expenditure functions are included. Demand elasticities are estimated and evaluated in order to find future policies to improve the national health by controlling the national tobacco consumption There are two econometric approaches app1ied in this study. The lent tobacco demand analysis method is mm tobacco consumption function model. Using national indices of tobacco price, tobacco consumption and other related variables, tobacco consumption function is estimated. The other is micro demand system analysis by using Korean urban households expenditure data during the period of 1991 to 1999. The own price elasticity which is estimated from national tobacco demand per capita is -0.19 for all people and -0.176 for the adults over 18, which means 100% price increase will cause decease of tobacco demand at 19% and 17.6% per each The cross vice elasticity which is estimated between tobacco and health expenditure of urban households demand system is -0.2328, which implies 100% of tobacco price increase will decrease 23.28% of health expenditure. The low price elasticities imply that tobacco price increase will increase total tobacco sales volume. 100% of tobacco price increase will bring about 79% increase of total tobacco sales volume according to our scenario. Korea's tobacco demand is negatively responsive to fluctuations in its price. The health expenditure is also negatively relatedto the tobacco price fluctuation. These empirical outputs could be utilized as the basis of government's tax policy to control national tobacco consumption in the future.

This study investigated that what strategies tobacco companies have taken for marketing tobacco and tobacco companies on news media, by reviewing the previous research analyzing the tobacco companies' documents and the news coverage of tobacco. The tobacco document studies showed that tobacco companies have created close relationships with news media, a quid pro quo, by providing advertising and diverse forms of sponsorships and obtaining favored treatment on news coverage and have built networks with journalists by supporting journalist organizations. They have also supported thinktank groups and pro-smoking groups so as to represent and advocate their perspectives and assertions on news media and have utilized sponsorship of art and culture as pseuo-event for publicizing tobacco and tobacco companies on news media. Futhermore, news coverage of tobacco showed that news media tended to deal with tobacco issues lukewarmly, without a clear position and perspective and deliver naturally tobacco industry's perspective and message that smoking is controvertial rather than totally undesirable and unacceptable. Also, the news coverages have often reflected tobacco industry's publicity strategies identified in tobacco industry documents. This study suggests how tobacco industry access and utilize news media to obtain favorable news coverage, and thus it provides a rational of why tobacco industry's publicity activities have to be regulated.

Feeding preference of cigarette beetle, Lasioderma sewicorne F., on cured tobacco leaves was investigated to obtain basic information on ecological management of the insect pest in tobacco storage warehouses. About 3, 000-4, 000 adults of the insect were released in a warehouse in which groud tobacco leaves were placed on the bottom and at 3m above the floor level, and numbers of insects attracted were examined. There was no significant difference on feeding preference between the two tobacco varieties, flue-cured(NC82) and air-cured(Br3l) tobacco leaves. However, significant differences were noted in feeding preference between thick and thin leaves and among different quality grades within a tobacco variety. Feeding preferences of cigarette beetle between flue- and air- cured tobacco varieties showed significant differences on the lower position, though there were no differences on the 3m upper position. On the 3m upper position, feeding preferences were different between thick and thin leaves of tobacco varieties, and variety X thickness and variety X thickness equality grades showed statistically significant differences. Significantly higher feeding preference by cigarette beetle adults was observed for the food placed on the 3m upper than on the lower position. There were negative correlations between quality grades of cured tobacco leaves and feeding preference on the lower position, and the regression equation was Y(feeding preference)=4.050-0.683 X (degree).

The involvement of health-care professionals in tobacco-control activities is essential to prevent smoking-related morbidity and mortality. The purposes of this predictive correlational study were to examine tobacco-control activities and to identify the predictors of such activities of community health practitioners (CHPs). Of the 1,813 members of the Korean Association of CHP, 1,247 participated in this study. A mailed survey was conducted to collect data. The majority of CHPs supported tobacco-control policies and recognized tobacco-control activities as an important role for them. Only $44.3\%$ of CHPs were confident in their knowledge and skills regarding tobacco-control activities, and only $30.8\%$ had received professional tobacco-control education. While the majority of the CHPs 'asked, advised, and assessed' their clients, only a small number 'assisted or arranged'. The tobacco-control activities of CHPs were predicted by their attitude toward it, age, experience of tobacco-control education, educational level, and general perception of the risk of smoking; these variables accounted $13.5\%$ of variance in the tobacco-control activities of CHPs. These findings provide the basis for developing a continuing education program for CHPs. CHPs should be encouraged to integrate tobacco-control activities into their routine practice, and CHP education programs should be adjusted to increase the time spent on the tobacco-control intervention techniques.

A fluorescent material was accumulated in inoculated leaves showing necrotic local lesions of tobacco plants with N gene, Nicotiana tabacum cvs. Xanthi-nc NN, Samsun NN, Burley 21 and KF 114, and N. glutinosa, and Datura stramonium at the early growth stages by the inoculation of Tobacco mosaic virus (TMV). It was identified as a coumarin phytoalexin, scopoletin. Although the material was most prominently produced in TMV-inoculated tobacco leaves with local necrotic lesions, its accumulation was also noted in uninoculated leaves of TMV-inoculated plants. Its accumulation was somewhat greater in high resistance-induced leaves than low resistance-induced and intact leaves. Scopoletin treatment induced the expression of a pathogenesis-related protein, PR-1, prominently at the concentration of 500 or 1000 ${\mu}$g/ml. This suggests that scopoletin is a phytoalexin abundantly accumulating in N gene-containing resistant plants in response to TMV infection, and may be related to hypersensitive responses (HR) and systemic acquired resistance (SAR) in the resistant tobacco plants.

The significance of soil and/or rhisosphere populations of Erwinia carotovora sobsp. carotovora (Ecc) as a source of primary inoculum for tobacco hollow stalk disease has been demonstrated conclusively. The survival of Ecc in field soils fter overwintering was estimated by using the enrichment technique. The population number of pectolytic erwinia (PE) in field soils relatively decreased at the rate of 102-104 colony forming unit(CFU) per g of soil after overwintering. Higher level of PE population overwintered in the rhlzosphere foils of tobacco stubbles and detected more frequently in rhizosphere soils of weed plants than in those of bare fields. All of the tobacco stubbles collected from fields where tobacco had been grown the previous year contained Ecc. The more survived population number of PE at the 30cm depth of artifitiany infested soils than at the upper of those by introducing with diseased tobacco plant tissue after overwintering. Ecc overwintered effectively in rhizosphere soils of tobacco stubbles, overwintered weeds and tobacco debris in field soils.

The experiment was carried out to study the effect of dry ice expanded tobacco (DIET) blending ratio on the physical properties of cigarettes. Vnencapsulated pressure drop (UPD) of the cigarette decreased from 85 mmWG to 78 mWG when the DIET blending ratio increased from 0% to 60%, but it increased in the range of over 60% blending ratio. But the overall UPD/EPD ratio of these cigarettes showed a decreasing tendency. Cigarette ventilation rate increased from 55% to 66% with the increased blending ratio of expanded tobacco and loose ends also showed the same tendency. The higher the blending ratio of expanded tobacco, the faster became the static burning time from 7' 34" to 5' 02". However, the cigarette hardness was almost not affected by the blending ratio.ing ratio.
