The t-wise intersection is a useful property of a linear code due to its many applications. Recently, the second author determined the t-wise intersection of a relative two-weight code. By using this result and generalizing the finite projective geometry method, we will present the t-wise intersection of a relative three-weight code and its applications in this paper.
We define an operator version of the relative Rényi entropy as the generalization of relative von Neumann entropy, and provide its fundamental properties and the bounds for its trace value. Moreover, we see an effect of the relative Rényi entropy under tensor product, and show the sub-additivity for density matrices.
This article coined a general class of estimators for various measures in normal population when some' a priori' or guessed value of standard deviation a is available in addition to sample information. The class of estimators is primarily defined for a function of standard deviation. An unbiased estimator and the minimum mean squared error estimator are worked out and the suggested class of estimators is compared with these classical estimators. Numerical computations in terms of percent relative efficiency and absolute relative bias established the merits of the proposed class of estimators especially for small samples. Simulation study confirms the excellence of the proposed class of estimators. The beauty of this article lies in estimation of various measures like standard deviation, variance, Fisher information, precision of sample mean, process capability index
A cost analysis for hospitalized patients was performed based on the RBRVS in order to determine an appropriate nursing fee schedule. The study was conducted through three phases as follows: 1) Nursing activities provided for the inpatients currently in Korea were identified and classified using a taxonomy which was developed by our research team through the Delphi process. 2) The resource-based relative points for every nursing activity according to nursing time, mental effort and judgement, technical skill, physical effort and stress were determined through a survey of 300 clinical RNs working at 5 tertiary hospitals from May 25 to July 25. 1998. 3) The nursing cost of every nursing activity for hospitalized patients was estimated based on the RBRVS. As a result, 136 nursing activities were identified and classified by nursing processes and nursing domains. However, our classification system of nursing activities should continue to be refined, and all nursing practices should be standardized. The nursing activities were given resource-based relative points ranging from 100 to 400 points, then each nursing activity was assigned a value for the RBRVS, which was determined by the exponential function of 2resource-based relative point/100. Thus, a value of 2 was calculated for 100 points, 4 for 200 points, 8 for 300 points, and 16 for 400 points. Meanwhile, the unit cost of nursing was calculated as 170 Won. The nursing cost of 136 nursing activities was estimated using the RBRVS as shown in
