Developing a case-mix methodology for home health services is more difficult than developing one for hospitalization and acute health services, because the determinants of need for home health care are more complex and because of the difficulty in defining episodes of care. To evaluate home health service case mix, a multivariate grouping methodology was applied to records from the 1982 Nationa...

This article discusses the Severity of Illness case-mix groups, and suggests a refinement to diagnosis-related groups (DRG's) designed to accommodate the important element of patient severity. An application of the suggested refinement is presented in a discussion of the efficient production of hospital services. The following areas are addressed. A brief summary of the goals and development of...

System BV is an extension of multiplicative linear logic (MLL) with the rules mix, nullary mix, and a self-dual, non-commutative logical operator, called seq. While the rulesmix and nullary mix extend the deductive system, the operator seq extends the language of MLL. Due to the operator seq, system BV extends the applications of MLL to those where sequential composition is crucial, e.g., concu...

In this paper we explore the problem of maximizing revenue for an Internet service firm that operates in a market of unique short-lived products that have uncertain demand. We look at the short-term problem where the firm has a capacity constraint and has to choose an appropriate product mix such that customers' desired quality-of-service requirements are fulfilled. For example, converging digi...

Anonymous networks enable entities to send messages without disclosing their identities. Many anonymous networks had been proposed already, such as Mixnet, DC-net, Crowds, etc., however, they still have serious drawbacks. Namely, they require tremendous computation overheads to transmit messages over networks. That is because asymmetric key encryption algorithms are used. This paper proposes ES...

Existing stable matching algorithms reveal the preferences of all participants, as well as the history of matches made and broken in the course of computing a stable match. This information leakage not only violates the privacy of participants, but also leaves matching algorithms vulnerable to manipulation [8, 10, 25]. To address these limitations, this paper proposes a private stable matching ...

We make use of a universal re-encryption mixnet to efficiently perform a secure multiparty computation to generate a secret permutation. When complete, the permutation is shared among the players in such a way that each player knows his share of the permutation but no others. Such a permutation is useful in dining cryptographers networks (DC-nets) to determine in which slot each player should t...

purpose:     methods:     results:     conclusion:     our study suggests that using mpcd method is an effective way to increase clinical reasoning skills of medical students. the attitude of students about the positive effects of mpcd increased significantly from the first day to the last day (p intervention. 120 third-year medical students at our medical university were randomly assigned to 1...
