- KonferenzbeitragPartial Order Concepts in Ranking Environmental Chemicals(Environmental Informatics and Systems Research, 2007) Brüggemann, Rainer; Voigt, Kristina; Sørensen, Peter B.; De Baets, BernardWith the discussion around REACH the interest in ranking of chemicals is increased. In this paper we take a statistical point of view in evaluation and ranking of chemicals. The data matrix with relevant properties of the chemicals plays the central role. Its evaluation is performed by simple concepts of partial order (Hasse diagram technique (HDT)). Several extensions are discussed: First the concept of METEOR (METhod of Evaluation by ORder Theory), then the approach by fuzzy concepts, combined with partial order, and finally the DLPO-concept (Double Layer Partial Orders). DLPO is a novel method where attributes are themselves combined by partial order. The main idea is to avoid the bias due to a functional combination of attributes (for example by weighted sums as in METEOR). Whereas HDT does not need any information beyond the data matrix, all other methods discussed so far, need additional knowledge.
- KonferenzbeitragRisk Assessment, Cost-Benefit Analysis and Knowledge Management in Food Safety Risk Analysis: An Economist’s Perspective on Tools for Decision Making(Environmental Informatics and Systems Research, 2007) McLaughlin, ChristinaRisk analysis is the framework for decision makers and regulators to use risk assessment, risk management, costbenefit analysis (CBA), and risk communication in order to reduce the public impact of risks, especially, health and safety risks. The primary mission of FDA’s Center for Food Safety and Applied Nutrition (CFSAN) is to protect the public health by ensuring that food is safe. Decision makers rely on a risk analysis framework to evaluate risk management options for implementing food safety programs and policies. The standard paradigm states that risk analysis is made up of three components: risk assessment, risk management and risk communication. It is also argued that components should be kept separate in the interest of scientific integrity and to make sure results are not affected by political pressure. However, it is important to maintain interaction among the different components of risk analysis so that the risk assessment along with the CBA can aid risk management in decision making. CBA needs to be part of risk analysis.
- KonferenzbeitragA Web-based System to Support e-Collaboration in the Design and Construction of Environmental Models(Environmental Informatics and Systems Research, 2007) Brito, Halisson; Strauch, Julia; Souza, JanoDesign and construction of environmental models are usually complex tasks that can be considerably improved with collaboration among design teams. Knowledge Management can also play an important role in these tasks, facilitating knowledge acquisition, dissemination and reuse. This paper presents a Web-based system to support e-collaboration in the design and construction of environmental models. The system is centered in Knowledge Management issues and also makes use of ontologies to increase the modeller’s abilities to obtain, share and reuse knowledge about models in order to improve the design of environmental models. These tools are also valuable in model validation and reuse.
- KonferenzbeitragMigrating to Modern Web Technologies - Experiences in Re-Designing a Substance Retrieval Systems(Environmental Informatics and Systems Research, 2007) Menger, Matthias; Jahnke, Petra; Eiblmaier, JosefThe successfully running search & retrieval applications for the substance database GSBL have been coming to age and need to reflect more the new needs of users dealing with modern networks and infrastructures. In its first version, the substance database GSBL used to be a classical desktop application. Performant access (the combination of throughput, response time, availability, and functionalities) was restricted to a narrow group of users having a desktop (fat) client installed. This allows a very performing client application with a wide range of functionalities which make this search & retrieval system unique in its class of substance information systems. Search and retrieval of substructures in more than 200.000 chemicals within a fraction of a second has been just one essential feature. With the growing of wider and better networks, more users and the approach to use software as a service, the obstacles of a pure client application become obvious. Innovative Web technologies and the availability of ever better performing networks allow to provide information to broad public more easily, faster and more convenient. Functionalities for search & retrieval do not need a fat client including installation and administration burdens. Just using your browser to get the same qualified information from everywhere you have access to the network was the aim of the re-design. Therefore, the cutting-edge technologies like Apache STRUTS, Ajax and JSTL were applied to create an easy to handle and efficient web application named 'GSBL Web application 3.0'. The following paper will describe the choice of technologies which fulfil best the needs of current and potential GSBL-users. This re-design allows continuing the successfully running service for environmental relevant information for chemical substances. The combination of continuously updated, comprehensive and reliable environmental data of the Federal Environment Agency (Umweltbundesamt) with InfoChem’s expertise in substance and structure handling make this application is an indispensable resource for public environmental authorities, first action forces, and governmental departments in the legislative process.
- KonferenzbeitragIntegrated Model-Based Decision Support for Management of Weather-Related Agricultural Losses(Environmental Informatics and Systems Research, 2007) Ermolieva, Tatiana; Romaniuk, Maciej; Fischer, Günther; Makowski, MarekThe natural catastrophes lead to severe losses for agricultural production and decrease of farmers’ income. These problems are especially important for poor and underdeveloped countries, which also face huge disasters like hurricanes, droughts, floods and earthquakes. Classical mechanisms of insurance may not be sufficient or not enough developed in these countries. In this paper we discuss an integrated catastrophic risk management model, which consists of a few layers of insurance and financial instruments.
- KonferenzbeitragStatus and Prospects in Geo Raster Service Standardization(Environmental Informatics and Systems Research, 2007) Baumann, PeterIncreasingly raster data are becoming integral component of geo services, since today’s hardware and software technology is powerful enough to allow online access even to objects of Terabyte to Petabyte size. The logical next step from standalone geo Web services are interoperable, community-sharable archive networks, and this raises the question of standardised access interfaces. The Open GeoSpatial Consortium (OGC) develops and promotes geo raster services as part of their geo service standards. Recently version 1.1 of the Web Coverage Service (WCS) has been released, and the Web Coverage Processing Service (WCPS) as a dynamic value-adding raster processing service is under preparation. Both WCS and WCPS are presented in this contribution. The author ist active member of the OGC WCS Revision Working Group, Chair of the WCPS Working Group, and Co-Chair of the Coverages Working Group.

- KonferenzbeitragIndicators of Waste Exposure in an Area of Campania (Southern Italy) Characterized by Numerous Dumping Sites(Environmental Informatics and Systems Research, 2007) Trinca, Stefania; Martini, Giovanna; Cossa, Luciana; Falleni, Fabrizio; Matteucci, Marzia; Piccardi, Augusta; Musmeci, LoredanaAs a task assigned by the Department of Civil Protection of the Italian Governement, a working group including WHO, CNR, ISS, OER and ARPA Campania has been established in order to check whether and how waste treatment in Campania Region could have repercussions on territory and resident population. To assess health risks from the presence of storage, treatment, disposal and illegal dumping sites of hazardous and nonhazardous waste, a number of data dating back to period 1997-2003 and coming from various administrations have been implemented in an apposite geo-database. By means of arcGIS software-platform a territorial analysis has been performed in terms of sites and municipalities. As a result, ‘synthetic descriptive indexes’ have been obtained in order to measure position-variability of such sites and of their potential health impact in the Provinces of Naples and Caserta. Our results represent a base for exposure assessment in epidemiological studies now in progress.
- KonferenzbeitragNew Methods including Picture Processing for Hydro-Meteorological On-Line Data Acquisition(Environmental Informatics and Systems Research, 2007) Kollmitzer, Christian; Skritek, Paul; Woletz, Kurt; Stadler, HermannEarly warning systems, quality control networks and sustainable protection of drinking water resources became more and more important as a main task of water resources management. They heavily rely on on-line measurements, which mostly are automated. Nevertheless the quality of the measured data can be increased by an integrated Quality Management System, including also the field measurement devices into a complete chain of quality traceability. To increase the data reliability alternative measuring methods have to be evaluated. In our prototype development staff gauge images are digitally processed to achieve a second value for the actual water-level. If the both detected water levels are different, an alarm is generated or remote configuration procedures are performed. The system is a contribution to an integrated Quality Management Tool, allowing retracing the complete chain of measuring value acquisition. Low Earth Orbit Satellites then allow worldwide “nomadic” on-line data-communication from otherwise inaccessible regions. Their combination with plausibility tests in the run-up to the database enables us to accept the great challenge of "real-time" supervision of the quality of the measurements.
