Objectives The aims of this study were to compare the performance of machine learning methods for the prediction of the medical costs associated with spinal fusion in terms of profit or loss in Taiwan Diagnosis-Related Groups (Tw-DRGs) and to apply these methods to explore the important factors associated with the medical costs of spinal fusion. Methods A data set was obtained from a regional...

Objectives The aim of this article is to study patient satisfaction with complementary and alternative medicine (CAM) in an in-hospital setting before and after the introduction of diagnosis-related groups (DRGs). Methods Patients were interviewed regarding a general evaluation of their hospital stay, the psychological talking therapy, the nutrition therapy, and the overall success of the tre...

Recall that nitrogen has five valence electrons and therefore requires three electrons or bonds to complete its octet (see Amine Tutorial). Based on this valence and bonding order, nitrogen forms three bonds in its neutral state and maintains one pair of non-bonded electrons (NBEs). In amides one of the three bonds is a carbonyl carbon. Thus amides may be viewed as "acylated amines" or as deriv...

In 1980, about 20 years after sequenceable groups were introduced by Gordon to construct row-complete latin squares, Keedwell published a survey of all the available results concerning sequencings. This was updated (jointly with Dénes) in 1991 and a short overview, including results about complete mappings and Rsequencings, was given in the CRC Handbook of Combinatorial Designs in 1995. In Sect...

<p>When working with a metric space, we are dealing the additive group (R, +). Replacing +) an Abelian (G, ?), offers new structure of space. We call it G-metric space and induced topology is called topology. In this paper, studying spaces based on L-groups (i.e., partially ordered groups which lattices). Some results in obtained. The defined further studied for its topological properties...
