“…[13141516] In most studies, smoking was associated with lower education, older age, and unemployment. [6101417] Particularly, education level is considered as a key demographic factor in predicting smoking,[61819] so that smoking rate significantly decreased with higher education level. Therefore, the role of education, which somehow leads to the promotion of health literacy, will be given further consideration.…”

Background:Smoking is a modifiable risk factor for noncommunicable diseases with a wide range of harmful health outcomes. Identification of sociodemographic characteristics of smokers can be a guideline to development of effective intervention proportional to target population. This study aimed to determine smoking pattern and its associated sociodemographic factors in Iran.Methods:This cross-sectional study was conducted based on data from the sixth round of nationwide STEPwise approach to Surveillance (STEPS) survey in the 31 provinces of Iran. A total of 10,834 participants aged ≥15 years were selected through a multistage cluster sampling method. Collecting data was performed via three-step questionnaire (ecological, behavioral risk factors, and physical and biochemical measurements). Data analysis was performed via Epi Info and then SPSS version 21 softwares using descriptive methods and analytical tests.Results:Of all participants, 9.6% were current cigarette smokers, which was significantly more frequent among men than women (21.5% vs. 1.1%, respectively, P < 0.001). Smoking was significantly associated with being self-employed and having under diploma education level (P < 0.05). Of all current cigarette smokers, 8.7% were daily smokers. The mean ± standard deviation of systolic blood pressure and history of cardiovascular symptoms in current smokers were higher than nonsmokers (P = 0.005 and P < 0.001, respectively). Coughing for >4 weeks, frequent wheezing, and shortness of breath were significantly more frequent in current smokers than nonsmokers (P < 0.001, P < 0.001, and P = 0.02, respectively).Conclusions:Our results draw a picture of sociodemographic distribution of smoking pattern to determine the specific characteristics of the target population affecting cigarette smoking and identified specific demographic strategies for preventive and control action plan.

“…Thermal radiation has obvious characteristics, including an abnormal duration, range, and morphology, and is closely related to the geological structure. Ionospheric total electron content (TEC) anomalies have been found to have occurred 8 hours before the Philippines earthquake (M7.6 on August 31, 2012), but these precursors may not always be detectable before every large-scale earthquake 11 . The region-time-length (RTL) algorithm has been widely used for investigating precursory seismicity changes before large and moderate earthquakes 12 .…”

After a triggering earthquake (TGE) occurs on one side of a plate boundary, it often produces a vertical-downward shift, which will cause a vertical-upward shift on the other side of the plate boundary, where after a long period of time, the stress may be re-accumulated and a large earthquake (triggered earthquake, TDE) may occur. The larger the magnitude of the TGE is, the greater the distance between the TGE and TDE will be, and the longer the time interval between the TGE and TDE will be. The correlations between the magnitude and distance and between the magnitude and time interval were calculated. Based on the regression equations, we verified 86 large earthquakes over the past 100 years with magnitudes greater than 6.6. The prediction process is similar to a mine sweeping game. Although only 63%–88% of large-scare earthquakes can be accurately predicted, earthquakes of M ≥ 9.0 and earthquakes that have caused significant casualties had all met our model with a prediction accuracy of 100 km and 3 days.
