Background: The term 'hardcore' has been applied to use of smoking tobacco and generally referred to as the inability or unwillingness of regular smokers to quit. The component constructs of hardcore except nicotine dependence are product neutral. With the use of 'time to first chew' as a measure of nicotine dependence, hardcore definition can be extended to characterize smokeless tobacco users. Hardcore users respond less to tobacco cessation interventions, and are prone to tobacco induced diseases including cancer. Thus identifying hardcore users would help in estimate the burden of high risk population for tobacco induced diseases. Smokeless tobacco use is predominant and accounts for more than 50% of oral cancer in India. Hence, hardcore chewing information could be used for planning of tobacco and cancer control interventions. The objective of this study was to assess the prevalence and associated factors of hardcore smokeless tobacco use in India. Materials and Methods: Global Adult Tobacco Survey (GATS)-India 2010 data were analyzed to quantify hardcore smokeless tobacco use in India with following five criteria: (1) current daily smokeless tobacco use; (2) no quit attempt in the past 12 months of survey or last quit attempt of less than 24 hours duration; (3) no intention to quit in next 12 months or not interested in quitting; (4) time to first use of smokeless tobacco product within 30 minutes of waking up; and (5) knowledge of smokeless tobacco hazards. Results: The number of hardcore smokeless tobacco users among adult Indians is estimated to be 5% (39.5 million). This group comprises 23.2% of daily smokeless tobacco users. The population prevalence varied from 1.4-9.1% across different national regions of India. Logistic regression modeling indicated age, education and employment status to be the major predictors of hardcore smokeless tobacco use in India. Conclusions: The presence of a huge number (39.5 million) of hardcore smokeless tobacco users is a challenge to tobacco control and cancer prevention in India. There is an unmet need for a universal tobacco cessation programme and intensification of anti-tobacco education in communities.

In empirical software engineering research, there is an increased use of questionnaires and surveys to collect information from practitioners. Typically, such data is then analyzed based on overall, descriptive statistics. Overall, they consider the whole survey population as a single group with some sampling techniques to extract varieties. In some cases, the population is also partitioned into sub-groups based on some background information. However, this does not reveal opinion diversity properly as similar opinions can exist in different segments of the population, whereas people within the same group might have different opinions. Even though existing approach can capture the general trends there is a risk that the opinions of different sub-groups are lost. The problem becomes more complex in case of longitudinal studies where minority opinions might fade or resolute over time. Survey based longitudinal data may have some potential patterns which can be extracted through a clustering process. It may reveal new information and attract attention to alternative perspectives. We suggest using a data mining approach to finding the diversity among the different groups in longitudinal studies (agile skeptics). In our study, we show that diversity can be revealed and tracked over time with the use of clustering approach, and the minorities have an opportunity to be heard.

This study attempted to demonstrate the role of perceived value and trust in the relationship between mobile banking service quality and use satisfaction. A survey was conducted on customers of Mongolian banks, and an analysis was conducted based on the collected data With the development of the fintech industry, the Internet-based mobile banking market is striving to provide convenient services to consumers. The result led to the introduction of an online-oriented Internet bank that can operate 24 hours a day regardless of time and space. The characteristic of operating only with the Internet has a positive aspect of providing services quickly and conveniently, but at the same time, including concerns about security and personal information leakage. This can make you hesitate to use the service. Therefore, we attempted to find out how the quality of mobile banking service affects the perceived value and satisfaction of using trust. A survey was conducted to verify the contents of the research model and hypothesis. This is to secure data to be used for empirical analysis of research hypotheses. The survey was conducted with 124 consumers in Ulaanbaatar, the capital of Mongolia. Based on the analysis results, we understood the satisfaction of consumers using mobile banking and suggested ways for consumers to improve their actual satisfaction using mobile banking. Specifically, service quality sensitivity, security, convenience, and design had a positive effect on perceived value or trust, ultimately leading to consumer satisfaction.

This paper analyzes the demand characteristics of DMB services using survey data. According to a Logit analysis, the willingness to adopt the services is higher if the would-be user is male, is better informed with the service, is watching TV longer, and is spending more for the telecommunications services. And the survey results tell us that for the stimulation of the service, efforts should be made to increase the level of public awareness of the services. The survey response from the would-be DMB users shows that the respondents who value the nationwide coverage and the numbers of channel are more inclined to use the satellite DMB service. On the other hand, the service charge and the availability of the terrestrial broadcasting channel for the time being does not seem to influence the intention of using the terrestrial DMB service. It could be interpreted that the potential user are deciding whether to use the service more by the quality and contents of the service rather than by the cost of the service.

Background: The results of the Global School Personnel Survey (GSPS) conducted in India in 2009 are compared with 2006 GSPS to assess any change in 2009 on tobacco use and knowledge and attitudes to tobacco use, training and availability of tobacco control teaching material in schools and the existence of school tobacco control policies. Methods: GSPS is a cross sectional survey conducted twice (2006 and 2009) in entire India. A total of 180 schools were surveyed each time. Results: Of the participating school personnel, 2660 in 2006 and 2575 in 2009, about 95% were teachers and the balance administrators. In 2009, compared to 2006 the prevalence of current smoking of cigarettes (19.6% in 2006 and 10.3% in 2009) and bidis (21.5% in 2006 and 13.9% in 2009) was found to be significantly lower; the percentage of teachers receiving training on preventing youth tobacco use has significantly reduced (16.7% in 2006 and 10.1% in 2009); access of teachers to educational materials on tobacco use and how to prevent its use among youth had not increased (34.6% in 2006 and 37.8% in 2009); there was no change in policy prohibiting tobacco use among students and school personnel; however, ever use of any tobacco on school premises was significantly lower (15.6% in 2006 and 9.6% in 2009). Conclusions: The prevalence of current smoking (cigarettes/bidis) among school personnel and use of any tobacco on school premises were significantly decreased in 2009 as compared to 2006. Necessary action should be planned to increase the number of teachers trained and the availability of teaching materials on preventing youth tobacco use in order to have effective prevention of tobacco use among students.
