BackgroundWe aimed to investigate the role of the physician in practice and the factors that influence the success rate of smoking cessation.MethodsThis study retrospectively analyzed 126 adult smokers who had visited the outpatient department of pulmonology, and received motivational interviewing with or without supplement drugs. The findings include continuous smoking abstinence rate, which was evaluated at 6, 12 and 24 weeks, and the factors associated with continuous abstinence for 6 months or longer.ResultsThe patients with only motivational interviewing accounted for 57.9%, while the nicotine patch therapy was applied to 30.2%; and varenicline was prescribed to 11.9%. The smoking cessation success rates of at 6, 12, and 24 weeks were 55.6%, 47.6%, and 33.3%, respectively. However, even in the failure group at six months, tobacco consumption was decreased under 10 cigarettes per day in 42.1% (53/126). In multivariate logistic regression analysis, degree of Fagerstöm Test for Nicotine Dependence (p=0.034; odds ratio, 3.607; 95% confidence interval [CI], 1.102-1.807), the absence of smoking-related lung disease (p=0.008; odds ratio, 4.693; 95% CI, 1.497-14.707), and education level (p=0.001; odds ratio, 181.420; 95% CI, 8.414-3,911.502) were the predictors of successful smoking cessation.ConclusionAn improved continuous smoking abstinence rate can be obtained by motivational interviewing, regardless of the association with pharmacotherapy.

Vibration testing is necessary for functionality and durability evaluations of equipment that may undergo performance degradation due to operational vibrations. Here, we propose a planning method for the vibration testing of equipment with high slenderness ratios, such as missiles, and excitation, support, and measurement locations are important factors for the test configuration. A finite element model was used to calculate the normal modes and suitability indexes, based on the excitation and support locations. The measurement locations were obtained via the effective-independence method. Indexes of the response of dominant modes to excitation were generated for each surface through vibration testing involving various excitation, support, and measurement locations. The suitability indexes of excitation and support locations, exhibited a high correlation with the indexes of response magnitude in the dominant modes of the equipment. Therefore, the vibration test configuration can be planned effectively by exciting dominant modes of equipment under test.
