BACKGROUND/AIMS As bacterial resistance to antimicrobial agents has grown due to the increasing use of antimicrobial agents, we sought to evaluate the suitability of ceftriaxone usage (representative of third generation cephalosporins) at 10 university hospitals in Korea. METHODS We prospectively evaluated the appropriateness of antibiotic usage in 400 adult patients who received ceftriaxone ...

In Geographic InfolTnation Systems spatial objects may change their spatiallocation and/or shapes over time. Query processing of such spatiotemporal objects consists of spatial query conditions and temporal query conditions. Dur study focuses on representing the spatiotemporal monitoring of a polygonal object and aims at developing an efficient data structure supporting queries and operations t...

Feeding low concentrations of DDGS early in the nursery period does not help to maintain growth performance when high concentrations of DDGS are incorporated in the diets during the late nursery period. Summary The objective of this experiment was to evaluate growth performance of weanlingpigs introduced to low concentrations (5%) of DDGS duringphase 2 of the nursery period followed by high con...

BACKGROUND Stress has been identified as one of the major public health issues in this century. New technologies offer opportunities to provide effective psychological interventions on a large scale. OBJECTIVE The aim of this study is to investigate the efficacy of Web- and computer-based stress-management interventions in adults relative to a control group. METHODS A meta-analysis was perf...

BACKGROUND The objective of the review was to evaluate the extent, quality and value of computer simulation modelling in population health and health care delivery. METHODS A narrative systematic review was carried out of world literature from 1980 to 1999, searching Medline, INSPEC, Embase, HealthSTAR, Science Citation Index, CINAHL, MathSci, INFORMS Online and SIGLE databases, and researche...

Categories are the most basic structures by which human beings understand, describe, and communicate phenomena and related information about the world (Lakoff, 1987). Geographers construct categories to conceptualize, define, interpret and communicate geographic phenomena, for instance, land cover, vegetation types, soil types, regions of economic growth, and many others. In general, categories...

This study investigated the effects of manipulating the load components of aerobic training sessions on the physical performance of rats. To achieve this purpose, adult male Wistar rats were divided into four groups: an untrained control (CON) group and training groups with a predominant overload in intensity (INT) or duration (DUR) or alternating and similar overloads in intensity and duration...

Associative memory for auditory-cued events involves specific plasticity in the primary auditory cortex (A1) that facilitates responses to tones which gain behavioral significance, by modifying representational parameters of sensory coding. Learning strategy, rather than the amount or content of learning, can determine this learning-induced cortical (high order) associative representational pla...

We study self-selection into contests among a large population of heterogeneous agents. We show that entry into the “richer” contest (in terms of show-up fees, number or value of prizes) is non-monotone in ability. Entry into the more meritocratic (i.e., discriminatory) contest exhibits two interior extrema. Other testable predictions of our model are: 1) All else equal, the more meritocratic c...
