In this tutorial, we introduce a differential equation simulation model for use in pharmacometrics involving NONMEM, Berkeley Madonna, and R. We report components of the simulation code and similarities/differences between software, rather than how to use each software. Depending on the purpose of the simulation, an appropriate tool can be selected for effective communication.

Selection of bacteria classification, collection the normal groups in sterility of vaccine and substances of national Institute of Vaccines (IVAC) of Nha Trang - Da Lat during 20 years (from 1983 to 2003). Cultured environment thioglycolate and Sabouraud. Gram's stain method and recognized and biochemical test were applied routinely by WHO. A computer software based on bacteria classification and SQL language in MS Access were developed by IVAC. This program was used for controlling sterility of vaccine and substances to follow GMP requirement in the future

The importance of software version in the medical device software supervision does not cause enough attention at present. First of all, the effect of software version in the medical device software supervision is discussed, and then the necessity of software version in the medical device software supervision is analyzed based on the discussion of the misunderstanding of software version. Finally the concrete suggestions on software version naming rules, software version supervision for the software in medical devices, and software version supervision scheme are proposed.

OBJECTIVETo accomplish the computation of Fisher exact probability test for fourfold table data in Excel.

METHODThe computing program of exact probability method for medical data in fourfold table design was edited by employing the IF statement and the relevant functions, such as SUM, FACT, DSUM, etc in Excel. The computational results are compared and evaluated according to the case studies.

RESULTSThe output of Fisher Exact Probability was generated and presented correctly following the input of four numerical values into the computation program in the setting of Excel. The parametric outcomes are in agreement with those produced by SAS and SPSS, in the combination tables containing the P value, two-tailed cumulative P value, left-tailed P-value, right-tailed P-value, Chi2 values and P values both for direct Chi-squared test and corrected Chi-squared test.

CONCLUSIONSDirect Chi-squared test, corrected Chi-squared test combined with Fisher Exact Probability test for fourfold table data can be conveniently, rapidly, and accurately accomplished in Excel.

This paper is maintenance of four kinds of failures of Carestream GC1.5 the workstation used several years to summarize, workstation software, change the host, burn, workstations transmission, and four kinds of failures of the specific case of itemized elimination steps are introduced.

OBJECTIVETo realize propensity score matching in PS Matching module of SPSS and interpret the analysis results.

METHODSThe R software and plug-in that could link with the corresponding versions of SPSS and propensity score matching package were installed. A PS matching module was added in the SPSS interface, and its use was demonstrated with test data.

RESULTSScore estimation and nearest neighbor matching was achieved with the PS matching module, and the results of qualitative and quantitative statistical description and evaluation were presented in the form of a graph matching.

CONCLUSIONPropensity score matching can be accomplished conveniently using SPSS software.
