Abstract:
ABSTRACT:Epilepsy encompasses medical, psychological, social and demographic factors which are best studied in large populations. The Canadian Epilepsy Database and Registry (CEDAR) is a comprehensive English language, multicentre epilepsy database which has been developed to study the impact of these and other factors on epilepsy in Canada. In addition, it can be used locally in the clinic for office record keeping, automated printout of a referral letter or graphing seizures and other data over time. The data in CEDAR are similar to what is found in the patient's chart. There are 20 participating centres across Canada which have entered data on over 8000 adult and pediatric epilepsy patients. The information in CEDAR will be available for research purposes to centres entering data as well as to academic researchers, the pharmaceutical industry and government agencies.

Abstract:
ObjectiveWe aimed to study the epidemiology of the prodromal and mild stages of Alzheimer’s disease (AD) patients who are eligible for clinical trials with disease-modifying therapies.SettingsWe analysed two large complementary databases to study the incidence and characteristics of this population on a nationwide scope in France from 2014 to 2018. The National Alzheimer Database contains data from 357 memory centres and 90 private neurologists. Data from 2014 to 2018 have been analysed.ParticipantsPatients, 50–85 years old, diagnosed with AD who had an Mini-Mental State Exam (MMSE) score of ≥20 were included. We excluded patients with mixed and non-AD neurocognitive disorders.Primary outcome measureDescriptive statistics of the population of interest was the primary measure.ResultsIn the National Alzheimer Database, 550 198 patients were assessed. Among them, 72 174 (13.1%) were diagnosed with AD and had an MMSE ≥20. Using corrections for specificity of clinical diagnosis of AD, we estimated that about 50 000 (9.1%) had a prodromal or mild AD. In the combined electronic clinical records database of 11 French expert memory centres, a diagnosis of prodromal or mild AD, certified by the use of cerebrospinal fluid AD biomarkers, could be established in 195 (1.3%) out of 14 596 patients.ConclusionsAD was not frequently diagnosed at a prodromal or mild dementia stage in France in 2014 to 2018. Diagnosis rarely relied on a pathophysiological marker even in expert memory centres. National databases will be valuable to monitor early stage AD diagnosis efficacy in memory centres when a disease-modifying treatment becomes available.

Abstract:
SummaryA multicentre database management system has been developed which permits individual centres to enter, update, and retrieve their data while allowing detailed analysis to take place on a multicentre basis. Individual centres can access only their own data; summaries, reports and graphics output can be used as a teaching device for seminars and rounds. In one instance, the system provides interactive services to 12 kidney transplant centres spanning a distance of 5000 kilometres; the database contains 20,000,000 items.The database management system is discussed and comparisons are made with other available systems.

Abstract:
Rare diseases constitute a major burden on public health, mainly due to the high cost of therapy and logistical difficulties (for example, the need to organise a network of designated treatment centres). National and international registries of rare diseases facilitate data collection and analysis for demographic, economic and research purposes. They are also useful for treatment centres and other healthcare providers and pharmaceutical companies developing orphan drugs. We present the HemoRec database, implemented in 2006 in six European countries, as an example of an international registry of inherited bleeding disorders. HemoRec is used in 15 Polish treatment centres and stores data on 1,100 patients with inherited bleeding disorders (amounting to 24.9% of all patients registered in the Polish central registry held at the Institute of Haematology and Blood Transfusion in Warsaw). It can be developed in the future into a national platform of data collection and exchange in the network of Polish, and hopefully also European, haemophilia treatment centres.

Abstract:
There is no central database that records the changing provision of prostheses in the United Kingdom. Experience suggests there have been some shifts in the population, particularly in the past decade. Because the detailed records of these changes are contained in the patients' medical records it is difficult to assess the substance of these data except on an individual basis; the larger picture requires the sifting of a centre's or many centres' data. This paper describes the analysis of one such set of records at the Oxford Limb Fitting Centre. It relates the profile of the population that attends the centre to the general population, and compares the information with that obtainable from other sources. The possible causes for the findings are discussed.

Abstract:
AbstractBackground:The Pediatric Heart Network Normal Echocardiogram Database Study had unanticipated challenges. We sought to describe these challenges and lessons learned to improve the design of future studies.Methods:Challenges were divided into three categories: enrolment, echocardiographic imaging, and protocol violations. Memoranda, Core Lab reports, and adjudication logs were reviewed. A centre-level questionnaire provided information regarding local processes for data collection. Descriptive statistics were used, and chi-square tests determined differences in imaging quality.Results:For the 19 participating centres, challenges with enrolment included variations in Institutional Review Board definitions of “retrospective” eligibility, overestimation of non-White participants, centre categorisation of Hispanic participants that differed from National Institutes of Health definitions, and exclusion of potential participants due to missing demographic data. Institutional Review Board amendments resolved many of these challenges. There was an unanticipated burden imposed on centres due to high numbers of echocardiograms that were reviewed but failed to meet submission criteria. Additionally, image transfer software malfunctions delayed Core Lab image review and feedback. Between the early and late study periods, the proportion of unacceptable echocardiograms submitted to the Core Lab decreased (14 versus 7%, p < 0.01). Most protocol violations were from eligibility violations and inadvertent protected health information disclosure (overall 2.5%). Adjudication committee reviews led to protocol changes.Conclusions:Numerous challenges encountered during the Normal Echocardiogram Database Study prolonged study enrolment. The retrospective design and flaws in image transfer software were key impediments to study completion and should be considered when designing future studies collecting echocardiographic images as a primary outcome.

Abstract:
Background For researchers working in gerontology or the demography of ageing, knowledge of and access to population-based data, which includes mature age respondents, is critical. The collection of metadata (information describing data) supports researchers in their search for relevant data. Aims This proof-of-concept project seeks to develop a metadata database including metadata on Australian sample surveys relevant to ageing over the period 2010–2018. Data and methods We used a five-stage approach to create the Centre for Excellence in Population Ageing Research (CEPAR) metadata database on ageing: 1) identification of in-scope survey datasets; 2) indexing the in-scope surveys; 3) scraping metadata from publicly available sources; 4) appending metadata to a master database; and 5) creation of a webtool to enable users to search and export metadata and obtain contact details for the relevant data custodian. Results The CEPAR Metadata Database webtool is available from: https://mspgh.unimelb.edu.au/centres-institutes/centre-for-health-policy/research-group/metadata-database. Conclusions Metadata database collections can assist researchers to identify what data has been collected (for their specific research interest in ageing), how it was collected and how to gain access to the data.

Abstract:
Our aim was to determine the effect of a national strategy for quality improvement in cancer management (the “Plan Cancer”) according to time period and to assess the influence of type and volume of hospital activity on in-hospital mortality (IHM) within a large national cohort of patients operated on for lung cancer.From January 2005 to December 2013, 76 235 patients were included in the French Administrative Database. Patient characteristics, hospital volume of activity and hospital type were analysed over three periods: 2005–2007, 2008–2010 and 2011–2013.Global crude IHM was 3.9%: 4.3% during 2005–2007, 4% during 2008–2010 and 3.5% during 2011–2013 (p<0.01). 296, 259 and 209 centres performed pulmonary resections in 2005–2007, 2008–2010 and 2011–2013, respectively (p<0.01). The risk of death was higher in centres performing <13 resections per year than in centres performing >43 resections per year (adjusted (a)OR 1.48, 95% CI 1.197–1.834). The risk of death was lower in the period 2011–2013 than in the period 2008–2010 (aOR 0.841, 95% CI 0.764–0.926). Adjustment variables (age, sex, Charlson score and type of resection) were significantly linked to IHM, whereas the type of hospital was not.The French national strategy for quality improvement seems to have induced a significant decrease in IHM.

Full text
Abstract:
The authors contribute to the developing literature on call centres by providing detailed empirical evidence on the spatial unevenness in the distribution of call centre activity. They argue that the driving forces of call centre growth, whether as the rationalisation of back-office functions or as entirely new entities, have been corporate strategy and the pursuit of low-cost competitive advantage. Thus, although technological developments at the heart of call centre operations render them relatively ‘footloose’ in locational terms, the search for specific characteristics makes certain regions (and parts of regions) more attractive than others. By using a sample database of call centres, the authors describe the characteristics of call centres in the United Kingdom in terms of size, sector, and spatial distribution. They then attempt to explain the determinants of call centre location at the county level through a multiple regression analysis. The results indicate that there is a propensity to site call centres close to existing concentrations of allied activity, with preferences for densely populated areas mediated by needs to maintain employee access and avoid staff turnover problems. This has important implications for the spatial division of labour, with call centre growth likely to reinforce existing spatial unevenness in employment in key service activities. The authors conclude by considering the implications of these findings for contemporary urban and regional development, as well as providing a number of suggestions for future research.

Abstract:
A l'origine de cette thèse il y a le constat d’une science en changement. Ce changement se caractérise par deux grandes tendances globales : la dépendance croissante à des grands équipements coûteux et partagés et la production de données de masse qui sont également très coûteuses à stocker et gérer. Dans les deux cas ces ressources sont financées par des programmes publics et proposés à la communauté scientifique selon un principe d’ouverture à des utilisateurs extérieurs sous forme de Infrastructures de recherche (IR). Plusieurs facteurs peuvent nous amener à penser que les IR sont des lieux favorables à la créativité. Cependant les moyens par lesquels les IR favorisent la créativité n’ont pas été étudiés. L’objectif de cette thèse est de répondre à cette question. La problématique se décline en deux sous-questions de recherche. D’abord nous nous demandons, comment les IR peuvent-elles contribuer à la créativité scientifique de leurs utilisateurs ? Puis nous nous interrogeons sur : comment mesurer cet impact ?
At the origin of this thesis there is the observation of a changing science. This change is characterized by two major global trends: the growing reliance on large expensive and shared equipment and the production of mass data which are also very expensive to store and manage. In both cases these resources are financed by public programs and proposed to the scientific community according to a principle of openness to external users in the form of Research Infrastructures (RIs). Several factors may lead us to believe that RIs are favourable places for creativity. However, the means by which RIs promote creativity have not been studied. The purpose of this thesis is to answer this question. The research question is divided into two sub-questions of research. First, we wonder how IRs can contribute to the scientific creativity of their users. Then we ask ourselves: how to measure this impact

Full text
Abstract:
Annotations play a key role in understanding and describing the data, and annotation management has become an integral component in most emerging applications such as scientific databases. Scientists need to exchange not only data but also their thoughts, comments and annotations on the data as well. Annotations represent comments, Lineage of data, description and much more. Therefore, several annotation management techniques have been proposed to efficiently and abstractly handle the annotations. However, with the increasing scale of collaboration and the extensive use of annotations among users and scientists, the number and size of the annotations may far exceed the size of the original data itself. However, current annotation management techniques don’t address large scale annotation management. In this work, we propose three chapters to that tackle the Big annotations from three different perspectives (1) User-Centric Annotation Propagation, (2) Proactive Annotation Management and (3) InsightNotes Summary-Based Querying. We capture users' preferences in profiles and personalizes the annotation propagation at query time by reporting the most relevant annotations (per tuple) for each user based on time plan. We provide three Time-Based plans, support static and dynamic profiles for each user. We support a proactive annotation management which suggests data tuples to be annotated in case new annotation has a reference to a data value and user doesn’t annotate the data precisely. Moreover, we provide an extension on the InsightNotes: Summary-Based Annotation Management in Relational Databases by adding query language that enable the user to query the annotation summaries and add predicates on the annotation summaries themselves. Our system is implemented inside PostgreSQL.

Abstract:
This thesis integrates three disciplines: geosciences, computer science, and museum collections management. Although these are not commonly integrated, by developing their intersection this thesis uniquely contributes a much-needed system for effectively managing geological collections. The lack of effective organization and management of collections can result in a serious problem: not only is history lost, but so is the potential for collection of further data from documented samples using newer analytical techniques. Using the Department of Geosciences at Virginia Tech as a beta testing ground, the electronic geological management system, EGEMS, was developed (Chapter 2). A database such as EGEMS should provide ready access to useful information including, a materialâ s provenance or current location, as well as any published analytical data. Past experiences volunteering in museums have allowed the author to design a system that is easily queried for such information. The organizational scheme and data model integral to the functionality of EGEMS was driven by direct experiences with geological research, in particular the electron microprobe analyses of Mn-rich minerals from the Hutter Mine, Virginia (Chapter 1). The final component of this thesis (Chapter 3) describes a facet of museum science that is most importantâ communication. This project records the development of a museum exhibit. Titled â The Search for the Mysterious Mineral,â this approach relies on pedagogical tools to engage the audience, and to illustrate how the scientific method used by a geologist is the same technique used in any problem solving. The exploration involved in these projects has lead to an enhanced understanding and appreciation for connections among generating, managing, and communicating geological information.

Abstract:
This thesis has developed a database solution for storage of interface data which are to different systems in a train, the interface data is used in the design of data communication between different systems in the vehicles. The database solution has focused on following problems: revision control of project related data, consistency of interface data between documentation and database, the possibility to roll back the database to an earlier revision, and the possibility to extract delta documents between two revisions in the database. For demonstration of the database solution, a user interface program has been created which communicates with the database. Revision control of the database has been solved by dividing the project related data into three sections: one approved, one modified, and one revised section. The approved section always contains the latest approved data and thereby the ability to read data even though it is subject for a revision at the moment. The modified section contains data that are currently being changed.  Obsolete data are stored in the revised section. To aviod inconsistency of interface data which are stored in both Word documents and in the database, the data is extracted from the database and inserted into tables in the Word documents. The Word documents contain bookmarks where the tables shall be inserted. Algorithms for rolling back the database to an earlier revision, and to extract delta documents were created. These algorithms are not implemented in the user interface program. As a result from this thesis, the interface data is revision controlled and no data is removed from the database during the change process; the data is moved between sections with different flags and revision numbers. Only if the database is rolled back to an earlier revision, data is removed. The functionality to transfer data from the database into tables in Word documents is verified.
Detta examensarbete har tagit fram en databaslösning för lagring av gränssnittsdata för olika systemenheter i ett tåg, gränssnittsdatat används i konstruktionen av kommunikation mellan olika system i fordonen. Databaslösningen har fokuserats på följande problem: revisionskontroll av projekt relaterat data, att gränssnittsdata överensstämmer mellan dokument och databasen, möjligheten att kunna gå tillbaks till en tidigare revision i databasen, samt möjligheten att kunna exportera delta dokument mellan två revisioner i databasen. För att demonstrera databaslösningen har ett användarprogram skapats som kommunicerar med databasen. Revisionskontroll i databasen har lösts genom att dela upp det projektrelaterade datat i tre sektioner: en godkänd, en modifierad samt en reviderad sektion. I den godkända sektionen finns alltid det senast godkända datat och möjligheten att läsa dessa data även om den är under ändring. I den modifierade sektonen finns data som är under pågående ändring. Data som har blivit ersatt återfinns i den reviderade sektionen. För att undvika inkonsekvens av gränssnittssdata som återfinns både i Word-dokument samt i databasen, extraheras datat från databasen till tabeller i Word-dokumenten. Word-dokumenten innehåller bokmärken där tabellerna sätts in. Algoritmer är framtagna för att kunna backa tillbaka till en tidigare revision i databasen samt kunna exportera delta dokument. Dessa algoritmer är inte implementerade i användarprogrammet. Detta examensarbete har resluterat i att gränssnittsdatat är revisionskontrollerat och inget data tas bort från databasen under en ändringsrutin, datat flyttas bara mellan olika sektioner med olika flaggor och revisionsnummer. Endast om man går tillbaks till en tidigare revision tas data bort ur databasen. Funktionaliteten att överföra gränssnittsdata från databasen till tabeller i Word-dokument är verifierad.

Abstract:
The efficient and flexible management of large datasets is one of the core requirements of modern business applications. Having access to consistent and up-to-date information is the foundation for operational, tactical, and strategic decision making. Within the last few years, the database community sparked a large number of extremely innovative research projects to push the envelope in the context of modern database system architectures. In this paper, we outline requirements and influencing factors to identify some of the hot research topics in database management systems. We argue that—even after 30 years of active database research—the time is right to rethink some of the core architectural principles and come up with novel approaches to meet the requirements of the next decades in data management. The sheer number of diverse and novel (e.g., scientific) application areas, the existence of modern hardware capabilities, and the need of large data centers to become more energy-efficient will be the drivers for database research in the years to come.

This research utilized a semi-structured survey instrument delivered to subject matter experts within the national network of fusion centers and employed a constant comparison method to analyze the survey results. This smart practice exploration informed through an appreciative inquiry lens found considerable variation in how fusion centers plan for, gather requirements, select and acquire federated search tools to bridge disparate databases. These findings confirmed the initial hypothesis that fusion centers have received very little guidance on how to bridge disconnected databases to enhance the analytical process. This research should contribute to the literature by offering a greater understanding of the challenges faced by fusion centers, when considering integrating federated search tools; by evaluating the importance of the planning, requirements gathering, selection and acquisition processes for integrating federated search tools; by acknowledging the challenges faced by some fusion centers during these integration processes; and identifying possible solutions to mitigate those challenges. As a result, the research will be useful to individual fusion centers and more broadly, the National Fusion Center Association, which provides leadership to the national network of fusion centers by sharing lessons learned, smart practices, and other policy guidance.

Abstract:
This thesis reports results of a research study into the usefulness of a user-centred approach for designing information retrieval interfaces. The main objective of the research was to examine the usability of an existing Web-based IR system in order to design a user-centred prototype Web interface. A series of usability experiments was carried out with the Web of Science. The first experiment was carried out using both novice and experienced users to see their performance and satisfaction with the interface. A set of search tasks was obtained from a user survey and was used in the study. The results showed that there were no significant differences in the time taken to complete the tasks, and the number of different search terms used between the two search groups. Novice users were significantly more satisfied with the interface than the experienced group. However, the experienced group was significantly more successful, and made fewer errors than the novice users. The second experiment was conducted on novices' learning and retention with the Web of Science using the same equipment, tasks and environment. The results of the original learning phase of the experiment showed that novices could readily pick up interface functionality when a brief training was provided. However, their retention of search skills weakened over time. Their subjective satisfaction with the interface also diminished from learning to retention. These findings suggested that the fundamental difficulties of searching IR systems still remain with the Web-based version. A heuristic evaluation was carried out to find out the usability problems in the Web of Science interface. Three human factors experts evaluate the interface. The heuristic evaluation was very helpful in identifying some interface design issues for Web IR systems. The most fundamental of these was increasing the match between system and the real world. The results of both the usability testing and the heuristic evaluations served as a baseline for designing a prototype Web interface. The prototype was designed based on a conceptual model of users' information seeking. Various usability evaluation methods were used to test the usability of the prototype system. After each round of testing, the interface was modified in accordance with the test findings. A summative evaluation of the prototype interface showed that both novice and experienced users improved their search performance. Comparative analysis with the earlier usability studies also showed significant improvements in performance and satisfaction with the prototype. These results show that user-centred methods can yield better interface design for IR systems.

Abstract:
Orphan wastes have properties preventing them from being managed according to existing or currently planned management routes, or lack characterisation so that their management is uncertain. The identification of new management opportunities for orphan wastes could realise significant benefits by reducing the number of processing facilities required, reducing waste volumes, reducing hazard or leading to the development of centres of excellence for the processing of certain types of orphan wastes. Information on the characteristics of orphan waste existing at nuclear licensed sites across the UK has been collated and a database developed to act as a repository for the information gathered. The database provides a capability to analyse the data and to explore possible treatment technologies for each orphan waste type. Thirty five distinct orphan waste types have been defined and possible treatment options considered. Treatment technologies (including chemical, high temperature, immobilisation and physical technologies) that could be applied to one or more of the generic orphan waste streams have been identified. Wiring diagrams have been used to highlight the waste treatment / lifecycle management options that are available for each of the generic orphan groups as well as identifying areas for further research and development. This work has identified the potential for optimising the management of orphan wastes in a number of areas, and many potential opportunities were identified. Such opportunities could be investigated by waste managers at waste producing nuclear sites, to facilitate the development of new management routes for orphan wastes.

Abstract:
Using object-oriented databases as the primary data source in VR applications has a variety of advantages, but requires the development of new techniques concerning data modeling, data handling and data transfer from a Virtual Reality system’s point of view. The many advantages are outlined in the first part of this paper. We first introduce versioning and collaboration techniques as our main motivation. These can also be used in the traditional file based approach, but are much more powerful when realized with a database on an object and attribute level. Using an object-oriented approach to data modeling, objects of the real world can be modeled more intuitively by defining appropriate classes with their relevant attributes. Furthermore, databases can function as central communication hubs for consistent multi user interaction. Besides, the use of databases with open interface standards allows to easily cooperate with other applications such as modeling tools and other data generators. The second part of this paper focuses on our approach to seamlessly integrate such databases in Virtual Reality systems. For this we developed an object-oriented internal graph database and linked it to object-oriented external databases for central storage and collaboration. Object classes defined by XML data schemata allow to easily integrate new data models in VR applications at run-time. A fully transparent database layer in the simulation system makes it easy to interchange the external database. We present the basic structure of our simulation graph database, as well as the mechanisms which are used to transparently map data and meta-data from the external database to the simulation database. To show the validity and flexibility of our approach selected applications realized with our simulation system so far e. g. applications based on geoinformation databases such as forest inventory systems and city models, applications in the field of distributed control and simulation of assembly lines or database-driven virtual testbeds applications for automatic map generation in planetary landing missions are introduced.

Abstract:
CARAIBES is the traceability information system in radioactive solid waste management of the French Atomic Energy Commission, (CEA). Initially developed for the reprocessing facility of low and intermediate level waste of the centre of Cadarache, it has been gradually enhanced to manage very low level waste and the facilities of the centres of Saclay and Fontenay-aux-Roses. This software is directly connectable to characterization equipment as X-Ray measurement, gamma spectrometric measurement and/or neutronic measurement. After 15 years of operation, a new information system should replace it in 2014. This new CARAIBES V2 will make the functional and technical improvements resulting from the CARAIBES feedback but will also allow to manage all produced and/or treated waste in the Atomic Energy Commission and to ensure the traceability of waste and waste treatment before and after its packaging. From the analysis of the processes, waste management was described as an iterative process where, in every step, the facility in charge of a waste will apply a treatment to it (packaging, association or division) and will characterize it in order to evacuate it towards the next facility. Associated with a strongly customizable information system, this process allows the management of all kind of radioactive waste, including radioactive liquids. The final objectives are: to share a unique software and only one database for all CEA’s facilities involved in radioactive waste management, to be able to track the radioactive waste through all steps of its process, to meet the user’s needs as well as the regulatory requirements.

Abstract:
Database modeling of engineering information is crucial for constructing manufacturing systems because current manufacturing industries are typically information-based enterprises and information systems have become their nervous center. Engineering information can be modeled at two levels: conceptual data model and logical database model. Generally a conceptual data model is designed and then the designed conceptual data model will be transformed into the chosen logical database schema. Imprecise and uncertain information, however, is generally involved in many engineering activities and imprecise and uncertain engineering information are represented by fuzzy sets. Nowadays relational databases are still the most useful database product and IDEF1X is most useful for logical database design of relational databases in engineering. So in this paper, we focus on fuzzy data modeling in IDEF1X and relational databases. The formal approaches to mapping fuzzy IDEF1X models to fuzzy relational database schemes are hereby developed.

Abstract:
This paper presents the results of statistical and engineering analysis of Loss of Offsite Power (LOOP) events registered in four reviewed databases. The paper includes events registered in IRSN (Institut de Radioprotection et de Sûreté Nucléaire) SAPIDE and GRS (Gesellschaft für Anlagen- und Reaktorsicherheit mbH) VERA database in time period 1992 to 2011. The Nuclear Regulatory Commission (NRC) Licensee Event Reports (LERs) database and the IAEA International Reporting System (IRS) database are screened for the relevant events registered in period 1990 to 2013. In total, 228 relevant events were identified in the IRSN database, 190 in GRS, 120 in LER and 52 in IRS. The data include events registered both during the critical (at power) and shutdown operation of the plants. The identified events were classified considering nine different categories. In the three databases (SAPIDE, VERA, IAEA-IRS) the largest numbers of events are registered for the plant centered category. The largest number of the events in the NRC-LER database is found for switchyard centered events. According to the mode of operation, most events were reported during critical power operation, in all four databases. The “Partial loss of external power” events are the most frequent type of event found in the IRSN and NRC databases while the “Physical loss of electrical busbars” is the main type in the GRS and IAEA databases. The largest number of events in all databases is identified for the switchyard failures followed by the interconnections failures (both lines and transformers). Mainly LOOP event are identified by the fault report in the control room. Electrical deficiency is detected as the main direct cause of events. Environment is registered as the main contributor for the electrical grid deficiency in the French and NRC databases. Electrical failures are dominant contributor to the electrical grid deficiency in the German and IAEA databases. The principal root cause for the LOOP events are human failures with the human errors during test, inspection and maintenance as the largest sub-group. The largest number of the LOOP events resulted in reactor trip followed by the Emergency Diesel Generator (EDG) start. The majority of the reported LOOP events lasted for more than 2 minutes. Main lessons learned from the analysed events and potential actions for decrease of the number of LOOP events are presented.

Abstract:
This paper presents the results of the trend analysis of Loss of Offsite Power (LOOP) events registered in two reviewed databases. The reviewed databases include the Nuclear Regulatory Commission (NRC) Licensee Event Reports (LERs) database and the IAEA International Reporting System (IRS). Both databases were screened for the relevant events registered in period 1990 to 2012. The statistical analysis of the identified relevant LOOP events is done. The analysis includes assessment of the LOOP initiating event frequency, distribution of the events per year in the analysed period and trend analysis of the identified events. The LOOP frequency is calculated for LOOP events registered in NRC LERs subdivided into four types by cause or location: plant centered, switchyard centered, grid related, and weather related. These four LOOP categories are assessed for two modes of operation (critical and shutdown operation). The number of LOOP events in each year over the analysed period and distribution of events per unit in given year were assessed from the reviewed databases. Trend analysis of the identified events is performed with the utilization of four trend measures. Analysis is done for events registered during power and shutdown operation and their sum. The obtained LOOP frequency for events registered NRC LERs for critical and shutdown mode is comparable to the one assessed in NUREG/CR-6890. Decreasing trend is obtained for the LOOP events registered for events in NRC LER database. Different trends are identified during critical and shutdown modes of operation for the events registered in the IAEA database. The sum of the LOOP events reported during critical and shutdown modes in IAEA IRS show no trend.

Abstract:
Computer-based information systems have become the nerve center of current manufacturing systems. Engineering information modeling in databases is thus essential. However, information imprecision and uncertainty extensively arise in engineering design and manufacturing. So contemporary engineering applications have put a requirement on imprecise and uncertain information modeling. Viewed from database systems, engineering information modeling can be identified at two levels: conceptual data modeling and logical database modeling and correspondingly we have conceptual data models and logical database models, respectively. In this paper, we first investigate information imprecision and uncertainty in engineering applications. Then EXPRESS-G, which is a graphical modeling tool of EXPRESS for conceptual data modeling of engineering information, and nested relational databases are extended based on possibility distribution theory, respectively, in order to model imprecise and uncertain engineering information. The formal methods to mapping fuzzy EXPRESS-G schema to fuzzy relational schema are developed.
