Forecasting medical resource requirements during combat operations is dependent upon reliable estimates of the anticipated patient load. Traditionally, mean patient load estimations are used to determine the medical resources and supplies. However, these approximations can underestimate the resources needed to treat casualties during certain peak periods of an operation. This paper discusses the use of percentile estimates in forecasting patient loads as an alternative to using measures of central tendency. To assist in providing alternative estimates of ground casualty rates, the SLICECAS model has been developed to compute the varying percentile estimates. Design and construction of the model is based on data and trends observed during previous combat operations.

modeling and simulation is one of the fastest growing areas of engineering. It is also one of the fastest growing areas of cutting edge research in the social sciences. And yet, there has been relatively little interaction between engineers and social scientists. The concept of interoperability suggests a broad program to integrate modeling and simulation across a range of disciplines. We argue in this paper that this is a particularly apposite agenda for the gap between the social sciences and engineering. There are a broad range of engineering problems for which the human element is critical. Developing approaches to modeling and simulation that will allow the incorporation of human behavior in consistent and systematic ways is an essential research frontier. To this end\ we briefly review how differences between social and physical systems may challenge the integration enterprise. Ultimately, a common language needs to be developed for interoperable modeling and simulation across disciplines. At the same time, the more effective incorporation of modeling and simulation into the social science learning environment, and making room for some exposure to the social sciences in the engineering curriculum will be essential for facilitating the kinds of collaboration that will be necessary for tackling a range of twenty-first century challenges.

The MMVR Conference is one of a handful of national forums where leading researchers regularly convene to discuss medical modeling and simulation. As such, the presentations made during the conference represent a reasonable overview of both the state-of-the-art in virtual reality in medicine and the basic and applied research trends in the field. This article describes those trends and some of the implications based on a meta-analysis of almost three hundred articles published as a result of the MMVR Conferences in 2000, 2001, and 2002.

Analysis of data taken in a human psychomotor experiment shows that high performance is associated with chaos in the mathematical sense. Thus realistic simulation of the behavior of high performing individuals should be mathematically chaotic. Some means to incorporate chaos into behavioral simulation are suggested.

Chinese medicine is among other traditional medical systems practiced either as a coadjutant intervention to Greek medicine or as the unique therapeutic intervention for illness prevention, treatment or rehabilitation. The complete spectrum from that traditional system includes acupuncture and moxibustion, herbal and food therapy, massage therapy （tuina）, physical exercises （taijiquan）, and breathing exercises （qigong）. In this article, it is presented several randomized controlled trials and systematic reviews on the application of all therapeutic modalities from Chinese medicine in the physical rehabilitation scenario. The discussed studies encompasses both ＂positive＂ and ＂negative＂ results of Chinese medicine intervention for disabilities due to illnesses of the nervous, musculoskeletal or cardiovascular systems. Additionally, the importance of the personalized approach for Chinese medicineand rehabilitation is emphasized together with the need for reproducible methods for pattern differentiation and intervention selection. Chinese medicine resources are recognized as promising methods for therapeutic rehabilitation and can be incorporated into the rehabilitation science. The wide variety of therapeutic resources explains why Chinese medicine is currently a multidisciplinary practice for health protection and promotion, early diagnosis and treatment as well as rehabilitation with roles in the public health care system.

The computation of the two-electron four-center integrals over gaussian basis functions is a significant component of the overall work of many ab initio methods used today, Improvements in the computational efficiency of the base algorithms have provided significant impact, Somewhat overlooked are methods that provide approximations to these integrals and their implementation in application software. A partial review of approximate integral techniques focused on the resolution of the identity (RI) four-center, two-electron integral approximation is given. The past and current uses of the RI algorithms are presented along with possibilities for further exploitation of the technology.
