The authors thank the german research community (DFG) for the support of the presented investigations whieh were realized inside the Special Research Area 326, named, J rocess Integrated Quality Control with Quality Information System for Metallic Parts in Mechanical Engineering, and special thanks to the scientific bilateral project between Brazil and Germany supported by the CNPq, KFA and DLR to realize the presented investigations in advanced radioscopy and tomography. 

The method used to develop the emission inventory does have some elements of error, but the other two alternatives are expensive and subject to their own errors. The first alternative would be to monitor continually every major source in the area. The second method would be to monitor continually the pollutants in the ambient air at many points and apply appropriate diffusion equations to calculate the emissions. In practice, the most informative system would be a combination of all three, knowledgeably applied. 

The CESARS database contains comprehensive environmental and health information on chemicals. It provides detailed descriptions of chemical toxicity to humans, mammals, aquatic and plant life, as well as data on physical chemical properties, and environmental fate and persistence. Each record consists of chemical identification information and provides descriptive data on up to 23 topic areas, ranging from chemical properties to toxicity to environmental transport and fate. Records are in English. Available online through CCINFOline from the Canadian Centre For Occupational Health and Safety (CCOHS) and Chemical Information System (CIS) on CD-ROM through CCIN-FOdisc. 

The overall conclusion that can be drawn from a survey of CPI data collection systems is that the better systems do attempt to address the causes of human error. However, because of the lack of knowledge about the factors which influence errors, the causal information that is collected may not be very useful in developing remedial strategies. General information in areas such as severity, work control aspects and the technical details of the incident will be required in all data collection systems. However, in almost all cases a structured process for causal analysis is lacking. Some of the requirements for causal analysis are set out in the following sections. 

With regard to the common European market, the European Economic Community (EEC) has undertaken numerous activities concerned with materials and material information systems. In one demonstration program for material databases eleven such databases from various countries in the EEC are being cooperatively developed with joint standards for terminology, data presentation, database access, and the user interface of search commands, aids, and menus. For the materials class of plastics, Polymat was selected to participate in this cooperative work. Interesting developments occur from which the users of central material databases in the entire EEC area can benefit. 

DAWN is a morbidity and mortality information system, funded by the National Institute on Drug Abuse, in which data are collected from a sample of more than 800 hospitals located in 27 major metropolitan areas in the continental United States, from a National panel of hospitals outside of these areas, and from medical examiners/coroners located in 26 major metropolitan areas. 

Computers. A certain number of personal computers are necessary for report generation and regulatory submission preparation. In addition, these may be useful for record keeping, depending on the type of stability information system that the company chooses to use. Alternatively, if the information system is intended to be accessible (read only) to many users, it may be more efficient to develop a local area network of mini-computers. The size of the database will help determine the nature of the software/hardware configuration used for this function. 

Analysis of biological data has now become far more complex, and there is a drive to develop software to allow disparate data sets, such as sequence, literature, clinical data and expression analyses, to all be accessible and interlinked. This allows movement between information systems and provides more complex meta-ana-lyses of these data sets, allowing a holistic view of biological research, in place of the current fragmented view we have available to us. This will ultimately lead to the blurring of boundaries between different disciplines, such as the areas of che-... 

Beyond playing a significant role as a measurement tool, audits provide the opportunity to share a set of fresh perspectives on areas where requirements have yet to be codified (e.g., process control procedures, management information systems, and maintenance programs). Audits also serve to indicate ongoing efforts to reexamine and reevaluate operations to further reduce operational risks and consequent liabilities (including property damage and business interruption). 

HTTP is designed beautifully for client-server and server-client communication and the design of HTML follows suit. They were not designed for server-server communications and some deficiencies in this area show up when implementing a distributed information system on top of HTT P/HTML. Fortunately, these are easy to work around. 

The NIH/EPA Chemical Information System (CIS), is a collection of computer programs and data bases which has been developed to support scientific and administrative needs of the two Agencies (1). This chapter about the CIS will be primarily devoted to those areas of the CIS which can and are being used by EPA in support of TSCA. The discussions here only relate to the scientific aspects of the system, particularly the area of analytical chemistry. 

While considerable progress has been made in the area of small molecule informatics over the past several decades, any effort in the field of polymers has been timid at best and there is considerable scope for development. The main reason for the virtual non-existence of polymer informatics is the complex nature of polymers. This review will therefore start with an examination of the particular informatics challenges posed by polymers, in particular in the area of polymer representation and will also discuss some of the peculiarities of polymer information ( the science of information ). It will look at information systems for polymers ( engineering of information systems ) and a final section will review attempts to develop structure-property relationships for polymers ( practice of information processing ). The modeling of polymers either on the molecular - or meso-level - is outside the scope of this review. 

Despite the benefits from stringent legislation and advances in environmental technology, the increase in the fleet of automotive vehicles and overpopulation in urban areas results in bad ah quality. It is estimated that up to 45% of Europe s urban population remains exposed to particulate concentrations above limit values, and up to 30% to ozone concentrations above target levels that assure human health protection. The concentrations of various pollutants in the atmosphere in various cities across Europe are shown in Table 1.4. The data in the table are from WHO s Healthy Cities Air Management Information System and the World Resources Institute, which relies on various national... 

Algorithm development in the areas of computer editing, data base management, sorting, computer-based composition, and text searching have been critical to the overall development of computer-based primary and secondary publications systems and text search services. Results of these developments are illustrated in the computer-based information system used at Chemical Abstracts Service (CAS) [ 1]. Lynch [2J describes principles and techniques for the computer-based information services and...
