The alluvial‐fan deposits in the Cretaceous Yongdong Basin, Korea, consist of conglomerates with a muddy or sandy matrix and sandstones thick thin laminations. occur commonly couplets, constituting apparently single sedimentation units. Facies transitions can be summed up tripartite facies sequence: (1) clast‐supported conglomerate parallel clast alignment (facies A B), (2) matrix‐supported coarse‐tail normally graded random orientation C) thickly stratified pebbly sandstone D), (3)...
To evaluate the risk of fractures related with zolpidem in elderly insomnia patients.Health claims data on entire South Korean population from January 2005 to June 2006 were extracted Health Insurance Review and Assessment Service database. We applied a case-crossover design. Cases defined as patients who had fracture diagnosis. set hazard period 1 day length prior date four control periods same at 5, 10, 15, 20 weeks date. Time independent confounding factors such age, gender, lifestyle,...
Objectives This study estimated the association of cardiovascular health behaviors with risk all-cause and disease (CVD) mortality in middle-aged men Korea. Methods In total, 12 538 aged 40 to 59 years were enrolled 1993 followed up through 2011. Cardiovascular metrics defined following lifestyle proposed by American Heart Association: smoking, physical activity, body mass index, diet habit score, total cholesterol, blood pressure, fasting glucose. The score was calculated as a single...
The aim of this study was to evaluate and quantify the risk both individual combined health behaviors on premature mortality in middle aged men Korea.
The presence of lamination on sedimentary rocks is a distinct characteristic, particularly in shales. They are due to the contrast between successive layers with regard grain size, composition, color, and structures, such as graded beds. Typically, degree controlled by sedimentation rate flow regime. Herein, we developed mudstone classification scheme terms because lamination-based shale facies related differing features mineral porosity, Young’s modulus. This study also attempts verify...

Objectives The aim of this study was to investigate whether a medium high degree total physical activity and indoor were associated with reduced all-cause cardiovascular mortality among elderly Korean women. Methods A prospective cohort done evaluate the association between mortality. made up (≥65 years age) subjects. Baseline information collected self-administered questionnaire linked death certificates retrieved from database. Cox proportional hazard models used estimate ratios (HRs) 95%...
The static modeling and dynamic simulation are essential critical processes in petroleum exploration development. In this study, lithofacies models for Wabiskaw Member Athabasca, Canada generated by multipoint statistics (MPS) then compared with the built sequential indicator (SIS). Three training images (TIs) selected from modern depositional environments; Orinoco River Delta estuary, Cobequid bay-Salmon Danube delta environment. order to validate models, average variance of similarity...
Calcium magnesium carbonate nanoparticles (CaMg(CO3)2 NPs), well-known as dolomite, are formed by the replacement of half calcite minerals limestone. The dolomite (CaMg(CO3)2) composed (CaCO3) and (MgCO3), both which offer promising strategies for maintaining growth development in mammals agricultural plants. A grounded mixture limestone was prepared via colloidal precipitates synthesis CaMg(CO3)2 NPs, their characteristics were examined using XRD, particle size analysis DLS, surface...
Shale reservoirs, the most important unconventional resource, are difficult to characterize. formations require detailed interpretation of geological, petrophysical, and geochemical analyses, an integration these disciplines. In terms geological interpretation, commonly used sequence stratigraphy analysis includes a lithofacies analysis. The application shales facilitates ability relate between mineral composition, petrophysical parameters, kerogen contents, which affected by depositional...

Background: In Korea, Cerebrovascular and cardiovascular diseases (CVD) were the second leading cause of deaths in 2011. 2010, American Heart Association (AHA) published health metrics (CVHM) aimed at reducing from all CVDs stroke, improving population as a whole. Despite their implications, AHA’s have not been broadly studied or previously applied to an Asian population. Objectives: This study estimated combined association behaviors on risk all-cause CVD mortality middle-aged men Korea....
