Background: Tobacco control and cessation interventions are among the most cost effective medical interventions but health systems in low resource countries lack the infrastructure to promote prevention and cessation among tobacco users. Workplace settings have the potential to provide opportunities and access for tobacco prevention interventions. Methods: This is a single group study evaluating tobacco use prevention and cessation through a structured three stage intervention program for tobacco users comprising education on harmful effects of tobacco, oral cancer screening and behavior therapy for tobacco cessation at the worksite. Results: All the 739 workers who were invited participated in tobacco awareness program and were screened for oral pre cancer lesions. 291 (39.4%) workers were found to be users of tobacco in some form. Education, gender and alcohol use (p<0.0001) were some of the factors associated with tobacco user status. The prevalence of clinical oral precancer lesions among tobacco users was 21.6%. Alcohol consumption (p<0.001), the type of tobacco consumed (p<0.018), personal medical history of chronic diseases (p<0.007) and combined use of alcohol and tobacco (p<0.001) were some factors found to be associated with presence of oral pre cancer lesions. Conclusion: An integrated approach for worksite based tobacco use prevention with oral cancer screening program showed good acceptance and participation and was effective in addressing the problem of tobacco consumption among the factory workers.

Control effect of an avirulent bacterlocin-producing strain(ABPS) Y6l-1 of Pseudomonas solanacearum on bacterial wilt was 58.8 % when the bacterial suspension had poured onto the rhizosphere soil of tobacco cultivar NC82 on one day before transplanting to the field and of hilling time. Until eight weeks after inoculation, survival of the strain on rhizoplane and in stem of the plants inoculated was better than that of other four strains tested. It suggested that survival of the ABPS in and on the plants should be supported for the sufficient protection.

For the Purpose of this study, were researched the optimum condition preconditioning condition of orient tobacco leaves . The loss of 3-methyl pentanoic acid (3-MP) component of BASMA leaves in the treatment process amount to about 60% , but the loss of 3-MP At the optimum conditions of BASMA CTC treatment, the temperature was 45-$65^{\circ}C$ and the treatment time 25-35 minutes. And further, the physical properties of BASMA after CTC treatment was remarkably similar to the control's. Since VTC minimized the loss, it is suggested that CTC method should be changed by VTC method.

South Korea's state health insurer, the National Health Insurance Service (NHIS), is in the process of a compensation suit against tobacco industry. The tobacco companies have habitually endeavored to ensure favorable outcomes in litigation by misusing scientific evidence or recruiting scientists to support its interests. This study analyzed strategies that tobacco companies have used during the NHIS litigation, which has been receiving world-wide attention. To understand the litigation strategies of tobacco companies, the present study reviewed the existing literature and carried out content analysis of petitions, preparatory documents, and supporting evidence submitted to the court by the NHIS and the tobacco companies during the suit. Tobacco companies misrepresented the World Health Organization (WHO) report's argument and misused scientific evidence, and removed the word "deadly" from the title of the citation. Tobacco companies submitted the research results of scientists who had worked as a consultant for the tobacco industry as evidence. Such litigation strategies employed by the tobacco companies internationally were applied similarly in Korean lawsuits. Results of tobacco litigation have a huge influence on tobacco control policies. For desirable outcomes of the suits, healthcare professionals need to pay a great deal of attention to the enormous volume of written opinions and supporting evidence that tobacco companies submit. They also need to face the fact that the companies engage in recruitment of scientists. Healthcare professionals should refuse to partner with tobacco industry, as recommended by Article 5.3 of the WHO Framework Convention on Tobacco Control.

We investigated the control of Bemisia tabaci adults in tomato greenhouses using the eggplant as a trap plant with 4 systemic chemicals. The control effect of dinotefuran SG 50% on tobacco whitefly adults was 80% mortality, the highest than that cyantraniliprole, pyridaben and clothianidin, 51.0%, 12.4% and 11.0% respectively when all chemicals with recommended doses were used. Dinotefuran was applied at various doses and was observed to be most effective above 200ppm (88.4%)t. The control effect of dinotefuran lasted for appromimately nine 9 days and the density of tobacco whitefly adults increased there after. In field tests, the densities of tobacco whitefly adults on tomato shoots were highest at points 0, 15 and 20 m from the eggplant traps and lowest at 5 and 10 m. When the density of tobacco whitefly was low and the eggplants with dinotefuran SG 50% were placed in the tomato greenhouse at 10 m intervals, the overall density of tobacco whitefly adults was lower. In addition, densities were higher at the side of the greenhouse than in the interior and further away from the eggplant. When the density of tobacco whitefly was high and the eggplants with dinotefuran were placed at 5 m intervals, the density of tobacco whitefly at each 5 m point decreased. Theses results confirm that the eggplant is an effective trap plant for attracting tobacco whitefly audlts and combined with dinotefuran SG 50% decreases the density of tobacco whitefly in tomato greenhouses.

Background: Smokeless tobacco use in South Asia is believed to be a significant contributor to morbidity and mortality. In India, only a few studies involving health educational intervention by health care providers have demonstrated reduction in smokeless tobacco usage. In the present study we assessed the cessation efforts towards smokeless tobacco by physicians in two high tobacco prevalence states of India. The study also identified opportunities and barriers for integration of tobacco cessation services in routine practices of physicians. Materials and Methods: This mixed method study involved qualitative (phase I) and quantitative research study (phase II). In phase I, 59 in-depth interviews with physicians were conducted. In phase II, a quantitative study conducted among 238 physicians. An inductive approach was followed to analyze qualitative data using ATLAS. Ti software. The Chi-square test was employed to test the association between different variables of interest using SPSS version 17. Results: The majority of physicians related only respiratory problems and cancer with smokeless tobacco. Other major health effects like cardio-vascular problems, oral diseases, and effects on reproductive and neonatal health were recognized only by a few physicians. The age-group of 10-19 years was identified as most vulnerable to smokeless tobacco use. Less than one-third of physicians reported recording smokeless tobacco history of all patients. Findings indicated that less than half of physicians provided information on harmful health effects of smokeless tobacco with regard to specific diseases. Conclusions: The study revealed a low level of knowledge of physicians about harmful effects of tobacco and their suboptimal engagement in tobacco control practices. The study indicates the need of capacity building initiatives to equip physicians with skills in tobacco cessation.

A sodium chloride crystallizer shows oscillatory and nonlinear characteristics under its nucleating and growing process. Because these characteristics vary with operational condition, we can't control the product crystal size exactly with a PID controller or a sequence controller. Then, we make a model with threefold neural networks for the laboratory equipment that is a jet mixing crystallizer. We try to control the product crystal size with its neuro-model, and we reach the conclusion that our neuro-model is applicable to the practical crystallizer.

The incidence of urban female breast cancer has been continuously increasing over the past decade with unknown etiology. One hypothesis for this increase is carcinogen exposure from tobacco. Therefore, the objective of this study was to investigate the risk of urban female breast cancer from tobacco smoke exposure. The matched case control study was conducted among Thai females, aged 17-76 years and living in Bangkok or its surrounding areas. A total of 444 pairs of cases and controls were recruited from the Thai National Cancer Institute. Cases were newly diagnosed and histologically confirmed as breast cancer while controls were selected from healthy women who visited a patient, matched by age ${\pm}5$ years. After obtaining informed consent, tobacco smoke exposure data and information on other potential risk factors were collected by interview. The analysis was performed by conditional logistic regression, and presented with odds ratio (ORs) and 95% confidence intervals(CI). From all subjects, 3.8% of cases and 3.4% of controls were active smokers while 11.0% of cases and 6.1% of controls were passive smokers. The highest to lowest sources of passive tobacco smoke were from spouses (40.8%), the workplace (36.8%) and public areas (26.3%), respectively. After adjusting for other potential risk factors or confounders, females with frequent low-dose passive smoke exposure (${\leq}7$ hours per week) from a spouse or workplace had adjusted odds ratio 3.77 (95%CI=1.11-12.82) and 4.02 (95%CI=1.04-15.50) higher risk of breast cancer compared with non-smokers, respectively. However, this study did not find any association of breast cancer risk in high dose passive tobacco smoke exposure, or a dose response relationship in cumulative passive tobacco smoke exposure per week, or in the active smoker group. In conclusion, passive smoke exposure may be one important risk factor of urban female breast cancer, particularly, from a spouse or workplace. This risk factor highlights the importance of avoiding tobacco smoke exposure as a key measure for breast cancer prevention and control.

This experiment was conducted to study the effect of soil water potenial on the growth and internal changes of stressed plants. The experimental imposition of soil water potential ( $\Psi$soil) were -0.1 to -0.2, -0.2 to -0.5, -0.5 to -3.0, -3.0 to -10.0 bar respectively. During water stress all growth rates were depressed, and the most sensitive period to water stress was found to be 10 to 25 days after transplanting. The water potential of leaf was declined rapidly within 12 hours after with holding of water. Nitrate reductase activity was decreased progressively as water deficit was built up in tobacco leaves, but the activity of alpha- amylase and super contents were increased. There were differences in peroxidase isozyme patterns between tile control and water stressed plant. New isozymes started to appear as tobacco leaf water potential decreased.
