[FPMULTI--a software for multi-layer composition and thickness analysis and its applications].

Main features of FPMULTI, a software for analyzing composition and thickness of multi-layer samples simultaneously using XRF, are briefly described in this paper. Based on fundamental parameter method, the software has the capability of determining multi-layer samples containing up to 10 layers and 25 elements. Calibration standards can be bulk or multi-layer of pure element or multi-element standards. Application examples for tin-plates, hot dip galvanized zinc-plates and 'fingerprint-resistant' plates were given. FPMULTI is used to predict the relationship between intensities of different X-ray lines and the thickness first and then to analyze those samples. When using only few calibration standards, the results from FPMULTI are much better than those from linear regression method, and this reflects the advantages of the fundamental parameter approach.

Information technology in the interventional pain practice: electronic medical records, practice management software, and document management.

Electronic medical records (EMR) can both replace the paper clinical chart and perform scheduling and billing tasks. EMRs are currently used in only a small proportion of medical practices; however, EMR adoption is expected to soar in a few years. Governmental and industry concerns about safety and quality, along with medical practice needs for increased productivity, are fueling this transition. Medical practices are likely to consider transitioning to EMRs. At this point, the marketplace is fragmented in terms of suppliers, and refinement of the software is continuing. Transitioning to an EMR is a step that offers enormous benefits to interventional pain management physicians, in terms of compliance, the ability to maintain quality, and the ability to manage practices, including larger and more complex practices. Transitioning to an EMR is also a major effort in terms of time and expense: the goal is to settle on a specific EMR and continue to use it. This review focuses on (1) why physicians are or are not transitioning to EMRs; (2) the benefits of a transition; and (3) factors to consider in evaluating the various competing software products. Although EMR technology continues to develop, the review also considers areas in which future development is necessary. The most important areas are seen in document management, data input, and outcomes analysis and decision support capability. The EMR market is evolving rapidly. However, this review should in no way serve as an endorsement of any particular system, vendor, or technology.

CalcDose: a software for drug dosage conversion using metabolically active mass of animals.

This Visual Basic computer program has been developed for drug dosage conversions using metabolically active mass (MAM) of the animals. The two body weights (one with known dosage and the other, for which the dosage has to be calculated) and the known dosage are entered in the respective input boxes and the appropriate units are selected using the option buttons. The program displays the report in the form of both the animals' body weights and the respective dosages in milligram per kilogram body weight as well as the total actual doses in milligrams. The object oriented layout, flexible data entry and comprehensive report format render the CalcDose software a convenient and handy tool for dosage conversions.

A rapid speech synthesizing software on a PDA for Japanese with speech impairments.

We developed a Japanese-language, rapid synthesizing software application for use on a personal digital assistant. It has an unrestricted vocabulary and can synthesize words and sentences within 3 s. Eight hundred common sentences and words are preregistered. By touching the first character at the head of a preregistered sentence or word from an on-screen Kana (Japanese alphabet) chart, the user can select the sentence or word to be spoken. Characters on the Kana chart can also be input sequentially. Two Japanese subjects with speech impairments rated the device highly for its portability and quick response. Whereas communication previously had to be done by writing or sign language, it was easy for listeners with or without specialized training in communication with persons with speech impairments to understand the output from this device, making conversation easier which, in turn, improved the quality of life and social activity of these persons with speech impairments.

Why did that happen? Exploring the proliferation of barely usable software in healthcare systems.

Clinicians and support staff are faced with increasingly complex computer applications. This complexity stems partly from the integration of heterogeneous systems ranging from computerized patient records to theatre management and dosage planning applications, and also from the increased functionality offered by the new generation of IT systems. Many members of clinical staff are bewildered by the vast array of configuration options and operating modes supported by computer based systems, while manufacturers often feel compelled to offer more and more software features to retain market position. These factors combine to create "usability" problems that have had a direct impact on patient outcomes as well as a number of indirect effects-for example, the costs of replacing and upgrading inadequate computer systems carry significant opportunity costs in terms of services that might otherwise have been funded. In the future we need to educate staff to reject substandard computer interfaces early in the acquisition process; encourage the use of human computer interaction techniques in health care; and train staff to recognize the dangers of "working around" poor interface design.

The development and validation of the Virtual Tissue Matrix, a software application that facilitates the review of tissue microarrays on line.

BACKGROUND: The Tissue Microarray (TMA) facilitates high-throughput analysis of hundreds of tissue specimens simultaneously. However, bottlenecks in the storage and manipulation of the data generated from TMA reviews have become apparent. A number of software applications have been developed to assist in image and data management; however no solution currently facilitates the easy online review, scoring and subsequent storage of images and data associated with TMA experimentation. RESULTS: This paper describes the design, development and validation of the Virtual Tissue Matrix (VTM). Through an intuitive HTML driven user interface, the VTM provides digital/virtual slide based images of each TMA core and a means to record observations on each TMA spot. Data generated from a TMA review is stored in an associated relational database, which facilitates the use of flexible scoring forms. The system allows multiple users to record their interpretation of each TMA spot for any parameters assessed. Images generated for the VTM were captured using a standard background lighting intensity and corrective algorithms were applied to each image to eliminate any background lighting hue inconsistencies or vignetting. Validation of the VTM involved examination of inter-and intra-observer variability between microscope and digital TMA reviews. Six bladder TMAs were immunohistochemically stained for E-Cadherin, beta-Catenin and PhosphoMet and were assessed by two reviewers for the amount of core and tumour present, the amount and intensity of membrane, cytoplasmic and nuclear staining. CONCLUSION: Results show that digital VTM images are representative of the original tissue viewed with a microscope. There were equivalent levels of inter-and intra-observer agreement for five out of the eight parameters assessed. Results also suggest that digital reviews may correct potential problems experienced when reviewing TMAs using a microscope, for example, removal of background lighting variance and tint, and potential disorientation of the reviewer, which may have resulted in the discrepancies evident in the remaining three parameters.

Development and testing of a PC-based system with menu-driven software for evaluating lung function in ICU patients.

This paper describes a portable PC-based system for measuring respiratory system resistance (Rrs) and dynamic lung compliance (Cdyn) in intubated and mechanically ventilated patients. A pneumotachometer placed immediately proximal to the endotracheal tube measures flow, and a pressure catheter with its tip at the distal end of the endotracheal tube measures lateral airway pressure. The software is menu driven and allows the user to select from options including patient information display and entry, data collection, data editing, and waveform display. Up to ten consecutive breaths can be analyzed per run. Rrs and Cdyn are calculated on a breath by breath basis. Results are displayed to the screen, output to the system printer, and written to a user-specified ACSII data file. The system was tested by measuring resistance and compliance in a model of the lung, and results compared with those calculated from analog signals. It was then used to make measurements in intubated post-operative patients. Results were comparable to those previously reported in intubated ICU patients without primary lung disease. We conclude that our system provides reliable measurements of lung mechanics in the intubated patient, and represents an inexpensive and more versatile alternative to microprocessor-based ventilator systems currently being marketed.

An automatized computer-method utilizing Procomm Plus and DataEase (4.2) PC and SAS (6.06) mainframe software for isolated, perfused guinea-pig heart studies.

A powerful, time sharing and automatized method of a comprehensive data analysis for isolated, perfused guinea-pig heart studies is described. Data are collected using DataEase PC software (version 4.2) into forms with data fields specified for vital parameters consistently recorded in isolated, perfused heart studies (HR, CBF, PEAKPRESSURE, DPDT, MVO2). After running, DataEase reports the data and information is uploaded to an IBM 3081D mainframe computer on each day of heart experiment and data collection. The uploading process, the data archival and the statistical analyses are automatized by Procomm Plus commands written in Aspect Source Program (.ASP) Files for logging, data transforming and file management procedures. The ASPCOMP.EXE compiler compiles these .ASP files into Aspect Script eXecutable (.ASX) programs, which run on the PC in our laboratory and activate WYLBUR (IBM 3081D Batch-job service and Command file processor) edited files in the mainframe's electronic devices then upload, backup and save data into these files. SAS EXE files containing program instructions for the data analyzing system are then forced by Procomm Plus to operate over the data just uploaded. SAS reads the DATA files by its INFILE facility and performs comprehensive statistical analyses and produces hard output including graphics and JOB reports of dose-response- and logaritmic scale curves for delivery to team members. This computerized and automatized method developed for isolated, perfused guinea-pig heart studies is capable of performing multiple file transfer, sophisticated statistical analyses and graphic procedures after one keystroke on the PC (Alt-F5 in Procomm Plus section) and also facilitates a consistent and convenient method for planning, controlling and standardizing experiments. The method is based on an interactive computer conversation between the PC in the laboratory and the remote's WYLBUR editor. No human presence is needed; however, in case of failure, Procomm Plus gives one of the team members supervising the system a phone call in order to get human help.

Kinetic modeling and fitting software for interconnected reaction schemes: VisKin.

Reaction kinetics for complex, highly interconnected kinetic schemes are modeled using analytical solutions to a system of ordinary differential equations. The algorithm employs standard linear algebra methods that are implemented using MatLab functions in a Visual Basic interface. A graphical user interface for simple entry of reaction schemes facilitates comparison of a variety of reaction schemes. To ensure microscopic balance, graph theory algorithms are used to determine violations of thermodynamic cycle constraints. Analytical solutions based on linear differential equations result in fast comparisons of first order kinetic rates and amplitudes as a function of changing ligand concentrations. For analysis of higher order kinetics, we also implemented a solution using numerical integration. To determine rate constants from experimental data, fitting algorithms that adjust rate constants to fit the model to imported data were implemented using the Levenberg-Marquardt algorithm or using Broyden-Fletcher-Goldfarb-Shanno methods. We have included the ability to carry out global fitting of data sets obtained at varying ligand concentrations. These tools are combined in a single package, which we have dubbed VisKin, to guide and analyze kinetic experiments. The software is available online for use on PCs.
