OBJECTIVES The purpose of the current study was to evaluate the usefulness of the following four comorbidity indices in gastric cancer patients who underwent surgery: Charlson Comorbidity Index (CCI), Cumulative Illness rating scale (CIRS), Index of Co-existent Disease (ICED), and Kaplan-Feinstein Scale (KFS). METHODS The study subjects were 614 adults who underwent surgery for gastric cancer...

Reliability is one of the main metrics transport system efficiency and quality service. For both travelers management organizations, high variance road travel times has become a problem. been identified as areas interest Strategic Highway Research Plan II. In order to evaluate congestion unexpected changes in time, reliability are increasingly used. GPS devices provide for exact assessment time...

OBJECTIVE To validate a protocol assessing upper limb kinematics using a planar robot among stroke patients. DESIGN Prospective cohort study. SUBJECTS Age-matched healthy subjects (n = 25) and stroke patients (n = 25). METHODS Various kinematic indices (n = 44) were obtained from 4 tasks performed by subjects with REAplan, a planar end-effector robotic device. The metrological properties ...

In this paper the problem of modeling electricity price dynamics in deregulated energy markets is studied. Since the nature of customers' energy consumption, market participants' strategic behavior and the power system reliability indices are stochastic processes, the electricity price model will be stochastic as well. In our analysis the price of electricity is modeled based on the customers' ...

In this paper, the redundancy and synchronization scheme for the high reliable surveillance data processing system for air traffic control is suggested. Two indices for reliability of surveillance data processing system are identified and full triple redundancy scheme and high availability software for the redundancy control are proposed. The synchronization issues among triple redundant nodes ...

This paper reviews some of the commonly used indices for measurement of gingivitis and periodontal disease. Periodontal disease should be measured using loss of attachment, not pocket depth. The reliability of several of the indices has been tested. Calibration and training of examiners seems to be an absolute requirement for a satisfactory inter-examiner reliability. Gingival and periodontal d...
