This study was conducted to develop the objective evaluation method for tobacco smoke. The evaluation was carried out by using the data of cut or blended tobacco components, smoke components, electric nose system (ENS), and sensory test. By using the statistical methods, such as cluster analysis, discriminant analysis, factor analysis, correlation analysis, and multiple regression analysis, the relationship among the data of tobacco, smoke, ENS, and sensory evaluation was studied. By the results of cluster analysis, the data from smoke analysis by GC and ENS were able to select the difference of tobacco leaf characteristics. As the results of discriminant analysis, grouping by the components of tobacco leaves and smoke was possible and the results of GC analysis of smoke could be used for discrimination of tobacco leaves. In the results of factor analysis, nicotine, tar, CO, puff No and pH in the smoke were the factors effecting on the tobacco leaf characteristics. From the correlation analysis, aroma, taste, irritation, and smoke volume of sensory test had high relation to tar, p-cresol threonolatone, levoglucosane, and quinic acid- ${\gamma}$ -lactone of smoke. The ENS data showed high efficiency for discriminant analysis and cluster analysis, but it was not good for factor analysis, and correlation analysis. It was possible to estimate tobacco leaves and their blending characteristics by the analytical data of tobacco leaves, smoke, ENS, and sensory test results. By the multiple regression analysis, some correlation among selected chemical components and sensory evaluation were found. This study strongly indicated that the some chemical analysis data was available for the objective evaluation of tobacco sensory attributes.

Tobacco leaves cultivated in Korea, U.S A., Greece and Turkey were analyzed for their essential oils that are solanone, nor- solanadione, damascenone, dana scone and mesa stigmatrienone (4- isomer). Regardless of tobacco varieties and cultivated localities, solanone was the most abundant. Among them particularly, Basma has the highest amounts of the solanone than other varieties. Flue-cured tobacco leaf has much higher amounts of damascellone than burley and aromatic tobacco leaf do. U.S. A. flue-cured, U.S. A. burley and Basma clave much higher concentration of solanone than corresponding Korean varieties, but significant differences could not be observed in other components. The order of total amounts of 8 essential oils in tobacco varieties were as follows; Aromatic) Burley) Flue-cured

Essential oil components were isolated from Korean aromatic tobaccos by using a simultaneous distillation and extraction apparatus. The essential oils were analyzed by GC/M S and date system. Forty-two volatile components were identified on the basis of their mass spectra. Determination of contents of essential oil components from Hyangcho and Sohyang was achieved by pseudo-multiple ion selection (Ml S) technique. Varietal differences were detected from the quantitative comparison of the MIS data.

Introduction: Andhra Pradesh (AP) is one of the largest tobacco producing states in India. About 29% of adults in AP currently use tobacco in some form. Almost 24% of males and 4% of females are smokers. The prevalence of tobacco use in the state is higher than the national average of 15% for male and 2% for female smokers. However, few attempts have been made to understand the current situation of tobacco control resources, activities and strategies in the context of such a high tobacco prevalence state. The present study aimed to identify the gaps in existing tobacco control program and areas where tobacco control efforts can be integrated. Methods: Data were collected using both quantitative and qualitative methods. Semi-structured interviews were undertaken with a total of 95 key officials of state health departments, program managers, and project directors in six districts to understand ongoing tobacco control efforts. To facilitate the interviews, semi-structured guides were developed. Simple descriptive statistical analysis was conducted on the quantitative data using SPSS version 17. Results: The results of the situational analysis suggest that a sufficient health workforce and infrastructure with the potential to integrate tobacco control activities is available in the surveyed districts. However, lack of integration of the tobacco control program intothe tuberculosis control program and the National Rural Health Mission was observed. Information, education and communication activities were lacking at block level health facilities. Conclusions: Our findings indicate that lack of trained health professionals, paucity of dedicated funds, lack of information, education and communication materials and low priority given to tobacco control activities are some of the factors which impede integration of tobacco control into existing health and developmental programmes in the districts of Andhra Pradesh, India.

This study was conducted to develop the method of hydrocarbon analysis and investigate hydrocarbon contents in flue-cured and burley tobacco leaves harvested in Korea and U.S.A. Tobacco leaf was extract with hexane in soxhlet apparatus. Hydrocarbon was fractionated from hexane extract by silica gel column chromatography, and then separated and indentified by GC, GC/MS using SE-54 fused silica capillary column. The developed method was feasible to analyze neophytadiene, normal and branched hydrocarbons from Clo to Cn. The result of recovery test was decade 99%, eicosane 100%, triacontane 102%. The major hydrocarbon of tobacco leaves were neophytadiene, nC3l, iC31, nC33, aC33, aC32, aC30 and nC29. The amount of total hydrocarbon in burley and flue-cured tobacco leaves harvested in U.S.A. and Korea were 4591, 2931, 2929 and 3015$\mu\textrm{g}$/g, respectively.

Objectives: This study was conducted to investigate dental hygienists' knowledge of smoking, attitudes toward tobacco cessation, and tobacco cessation education activities, which will serve as fundamental data for developing an effective tobacco cessation education program for dental hygienists. Methods: From 2020-08-17 to 2020-09-05, 184 dental hygienists working at dental clinics and hospitals in Gwangju and Jeollanam-do were surveyed. We performed t-tests, ANOVA, Pearson's correlation analysis, and multiple regression analyses. Results: Dental hygienists' smoking-related knowledge, expert attitudes toward tobacco cessation, and tobacco cessation education activities were all high in tobacco cessation education (p<0.05). According to the analysis of the dental hygienists' knowledge of smoking, attitude toward smoking, and correlation of tobacco cessation education activities, there was a significant amount of correlation (p<0.01). According to the analysis of factors affecting dental hygienists' tobacco cessation education activities, expert attitudes towards tobacco cessation (𝛽=0.434, p<0.001), tobacco cessation materials (𝛽=0.160, p=0.009), experience in tobacco cessation education while attending school (𝛽=0.152, p=0.010), and attitudes toward tobacco cessation (p<0.05) were statistically significant. Conclusions: The results of this study are utilized as fundamental data to develop an effective tobacco cessation education program, factoring in dental hygienists' attitudes toward tobacco cessation.

Some or the parameters affecting the thermal analysis of different types of ground tobacco have been discussed. The sample, Korean flue- cured and burley and Greek orient tobacco leaves were run in air at heating rate of $10^{\circ}$ and 20^{\circ}C$ per minute. The thermograms obtained were divided into four temperature zones. The effect of different heating rates on thermal degradation has been discussed At the lower heating rate the maxima of DTA curves in zone 3 and 4 were 25-$40^{\circ}C$ lower than that of the higher heating rate.

Cigarettes were prepared using cut tobacco blends containing 5 levels of expanded tobacco. The effect of expanded tobacco content and tobacco weight on the draw resistance, tar, nicotine, static burning rate, net weight, and carbon monoxide deliveries were examined. At the specified hardness, tar, and tricot me significantly decreased with increasing expanded tobacco rates as a consequence of the increasing cigarette draw resistance. In the view of the experts, the smoke analysis of the cigarettes containing the expanded tobacco was investigated.
