摘要： This British Standard specifies a data structure for recording names and identifiers of individuals and groups for the purposes of interoperability between information systems. The data structure is presented as a data model in Unified Modelling Language (UML). The model is formed around six basic classes of objects: person (see 4.1); person name (see 4.2); person identifier (see 4.3); group (see 4.4); group name (see 4.5) and group identifier (see 4.6). This British Standard defines the attributes of these classes of objects in structured English and in tabular format, and specifies the name of the attribute, the UML form of the attribute name, the definition of the attribute, whether the attribute is mandatory or optional, whether there can one be a single value of the attribute, or whether multiple values are allowed and the allowable values. This British Standard also presents the attributes as an example XML schema (see Annex E). This British Standard does not define how individual and group names are created. It does not prescribe any personal or group identifiers but does allow the use of existing identifiers such as National Insurance Number or customer reference number. This British Standard is aimed at information specialists, systems developers and users who have a primary interest or involvement in the interoperability of information systems that use names and identifiers of individuals and groups.

摘要： 在卫生信息领域中,卫生信息标准的统一,是进行信息资源交换与共享的基本前提。从目前我国临床实验室信息标准化方面看,实际上我们尚缺的主要信息标准之一就是临床实验室数据信息的通用编码标准。作为所有临床信息系统均可采用的,旨在标识各种实验室检测项目和临床观测指标的,观测指标标识符逻辑命名与编码系统 (LOINC)数据库,正是这样一个通用编码标准。从当前国际形势看,政府卫生部门和商业性医疗机构认可和采用LOINC代码的西方发达国家日趋增多。为此,主要对LOINC数据库的背景、用途、内容及国外应用现状进行了概括介绍。同时,作者还建议结合中国国情,为LOINC的顺利引进和尽快普及全面、深入、细致地做好基础性准备工作,促进临床实验室信息编码标准化的早日实现。

摘要： Protein identification by matrix-assisted laser desorption/ionization mass-spectrometry peptide mass fingerprinting (MALDI-MS PMF) represents a cornerstone of proteomics. However, it often fails to identify low-molecular-mass proteins, protein fragments, and protein mixtures reliably. To overcome these limitations, PMF can be complemented by tandem mass spectrometry and other search strategies for unambiguous protein identification. The present study explores the advantages of using a MALDI-MS-based approach, designated minimal protein identifier (MPI) approach, for protein identification. This is illustrated for culture supernatant (CSN) proteins of Mycobacterium tuberculosis H37Rv after separation by two-dimensional gel electrophoresis (2-DE). The MPI approach takes into consideration that proteins yield characteristic peptides upon proteolytic cleavage. In this study, peptide mixtures derived from tryptic protein cleavage were analyzed by MALDI-MS and the resulting spectra were compared with template spectra of previously identified counterparts. The MPI approach allowed protein identification by few protein-specific signature peptide masses and revealed truncated variants of mycobacterial elongation factor EF-Tu, previously not identified by PMF Furthermore, the MPI approach can be employed to track proteins in 2-DE gels, as demonstrated for the 14 kDa antigen, the 10 kDa chaperone, and the conserved hypothetical protein Rv0569 of M. tuberculosis H37Rv. Furthermore, it is shown that the power of the MPI approach strongly depends on distinct factors, most notably on the complexity of the proteome analyzed and accuracy of the mass spectrometer used for peptide mass determination.

关键词： probabilistic record linkage   patient identifiers   match weights   confidentiality  

摘要： As a linkage using less informative identifiers could lead to linkage errors, it is essential to quantify the information associated to each identifier. The aim of this study was to estimate the discriminating power of different identifiers susceptible to be used in a record linkage process. This work showed the interest of three identifiers when linking data concerning a same patient using an automatic procedure based on the method proposed by Jaro;the date of birth, the first and the last names seemed to be the more appropriate identifiers. Including a poorly discriminating identifier like gender did not improve the results. Moreover, adding a second christian name, often missing, increased linkage errors. On the contrary, it seemed that using a phonetic treatment adapted to the French language could improve the results of linkage in comparison to the Soundex. However, whatever, the method used it seems necessary to improve the quality of identifier collection as it could greatly influence linkage results.

摘要： The ID/LX1-S Mold Identifier is a mold-mountable device that allows un-instrumented molds to utilize the mold-identifying and job-startup features of RJG, Inc.'s eDART System. Designed to be mounted on either the moving or stationary mold half and to recognize each mold as it is placed in a machine, the Mold Identifier receives power and communications through a micro-connector that links the unit with the eDart System.

摘要： 在开始使用Lotus Notes邮件系统时,系统管理员要使用Lotus Administrator在邮件服务器上为每个用户注册邮件标识符,但生成大量用户标识符却不是一件轻松的事情.好在Lotus Notes为我们提供了批量生成的方法,我们可以使用文本编辑器创建一个纯文本文件,例如***.它包含每个邮件用户标识符的注册信息,每个用户占一行,其具体格式如下:

摘要： 在Windows中，有个名为类标识符的“家伙”，它的英文缩写为CLDID，它是一个16字节(128位)的符号代码，由“{}”号、数宇、字母组成，用来标识应用程序、文件、控件类型等对象，虽然几乎没有机会直接“看到”它们，但实际上我们会经常与它们打交道，类标识符的一个有趣的特性是在Windows中不会显示却可以像扩展名一样标识文件的类型，利用好类标识符可以实现一些特殊的功能。
