A common failure in endodontic treatment of the permanent maxillary first molars is likely to be caused by an inability locate, clean, and obturate second mesiobuccal (MB) canals. Because importance knowledge on these additional canals, there have been numerous studies which investigated molar MB root canal morphology using vivo laboratory methods. In this article, protocols, advantages disadvantages various methodologies for in-depth study were discussed. Furthermore, newly identified...
Objective. Micro-computed tomography (MCT) with alternative image reformatting techniques shows complex and detailed root canal anatomy. This study compared two-dimensional (2D) 3D MCT standard tooth clearing for studying mandibular first molar mesial morphology. Materials methods. Extracted human roots (n = 31) were scanned by (Skyscan 1172). 2D thin-slab minimum intensity projection (TS-MinIP) volume rendered images constructed. The same teeth then processed staining. For each root,...

In this study, 20 microbrewery beer samples collected from different regions in Korea were analyzed for their contents of biogenic amines as well physiochemical properties (pH, acidity and alcohol content). The separation involved derivatization with dansylchroride followed by subsequent analysis high-performance liquid chromatography. As a result, such tryptamine (nd–1.10), 2-phenylethylamine (nd–0.69), putrescine (0.53–3.56), cadaverine (0.10–1.56), histamine (0.13–2.65), tyramine...
Reliable and precise navigation technology is essential for robust detection discrimination of unexploded ordnance (UXO) in a wide range field conditions, including GPS-challenged environment. Based on the fact that UXO involves frequent stops, this paper proposes an adaptive ZUPT (AZUPT) algorithm sliding time window to guarantee correct identification zero velocity condition improve position accuracy geolocation. Furthermore, known velocity-based prefiltering method used remove INS sensor...

To use barley as a green manure crop, this study has been conducted in Suwon, Gyeonggi-do to establish the (BGM)-rice cropping system with emphasis on soil incorporation date and BGM density. The nitrogen (N) contents of rye barley, grass crops, were 1.4~2.4% at early growth stage decreased rapidly 0.6~1.0% late stage. biomass was 449 kg/l0a heading (HS) increased 421 kg/10a 10 days after (DAH), 473 20 DAH. C/N ratio lowest 26.3 HS. N range 0.9~1.5%, highest HS gradually decreased, output...

The new approach of multivariate Total Least-Squares (TLS) adjustment has been applied to 33 stations the horizontal network Seoul/Korea in order estimate best-fitting affine transformation parameters. results are presented along with variances and covariances (in first approximation), comparisons drawn standard (LS) approach. Although estimates from TLS do not show practical differences respect LS, fit does yield significant improvements. Furthermore, could be substantially different when...
