Master data quality management in a global enterprise

In a networked business environment the visibility requirements towards the supply operations and customer interface has become tighter. In order to meet those requirements the master data of case company is seen as an enabler. However the current state of master data and its quality are not seen good enough to meet those requirements. In this thesis the target of research was to develop a process for managing master data quality as a continuous process and find solutions to cleanse the current customer and supplier data to meet the quality requirements defined in that process. Based on the theory of Master Data Management and data cleansing, small amount of master data was analyzed and cleansed using one commercial data cleansing solution available on the market. This was conducted in cooperation with the vendor as a proof of concept. In the proof of concept the cleansing solution’s applicability to improve the quality of current master data was proved. Based on those findings and the theory of data management the recommendations and proposals for improving the quality of data were given. In the results was also discovered that the biggest reasons for poor data quality is the lack of data governance in the company, and the current master data solutions and its restrictions.

The burden of disease in Spain: results from the global burden of disease study 2010

BackgroundWe herein evaluate the Spanish population¿s trends in health burden by comparing results of two Global Burden of Diseases, Injuries, and Risk Factors Studies (the GBD studies) performed 20 years apart.MethodsData is part of the GBD study for 1990 and 2010. We present results for mortality, years of life lost (YLLs), years lived with disability, and disability-adjusted life years (DALYs) for the Spanish population. Uncertainty intervals for all measures have been estimated.ResultsNon-communicable diseases accounted for 3,703,400 (95% CI 3,648,270¿3,766,720) (91.3%) of 4,057,400 total deaths, in the Spanish population. Cardiovascular and circulatory diseases were the main cause of mortality among non-communicable diseases (34.7% of total deaths), followed by neoplasms (27.1% of total deaths). Neoplasms, cardiovascular and circulatory diseases, and chronic respiratory diseases were the top three leading causes for YLLs. The most important causes of DALYs in 2010 were neoplasms, cardiovascular and circulatory diseases, musculoskeletal disorders, and mental and behavioral disorders.ConclusionsMortality and disability in Spain have become even more linked to non-communicable diseases over the last years, following the worldwide trends. Cardiovascular and circulatory diseases, neoplasms, mental and behavioral disorders, and neurological disorders are the leading causes of mortality and disability. Specific focus is needed from health care providers and policy makers to develop health promotion and health education programs directed towards non-communicable disorders.

Intervenciones de identidad territorial en el proceso global de construcción de imagen de marca de los destinos turísticos

La competitividad emergente entre destinos turísticos ha puesto de manifiesto la necesidad de enfatizar las estrategias de comunicación –con el fin de crear un valor añadido intangible para el potencial cliente- encaminadas a crear una imagen favorable de los espacios que se pretenden promocionar, mediante el diseño de acciones de comunicación con objetivos que van más allá del mero interés promocional o informativo. En este sentido, tanto los emplazamientos que conciben el turismo como una solución de diversificación económica (destinos emergentes), como las localizaciones geográficas que ya disponen de una cierta solera en relación a su tradición turística (destinos maduros), aúnan esfuerzos en aras de consolidar una identidad territorial acorde con sus posibilidades turísticas. Si además se tiene en cuenta que, en la actualidad, el consumo de imágenes percibidas a priori representa, de antemano, un primer viaje simbólico previo a un posterior viaje real, se puede llegar a vislumbrar el papel decisivo que desempeña la interpretación del consumidor (creación de imaginarios individuales y colectivos) en un escenario global de comercialización del territorio. Por tanto, el valor añadido en una situación de dura competencia entre destinos, radica en los valores que se asocian a la imagen de marca turística, que representa la primera carga de sensaciones y emociones que percibe el potencial turista y/o visitante antes de decidirse por uno u otro destino.

Estudi i guia docent per a modelatge i simulació de sistemes mitjançant l'entron ARENA

Aquest projecte es basa en el modelatge i simulació de sistemes utilitzant un simulador digital, i pretén ser una guia docent com a eina d’ajuda per a una assignatura que, a priori, s’impartirà a la Universitat de Vic. La simulació és una tècnica que permet representar el comportament de processos (físics, productius, de serveis, etc.) sense necessitat d’accedir al sistema real. Per analitzar, estudiar i millorar el comportament d’un sistema mitjançant la tècnica de la simulació digital és necessari primer desenvolupar un model conceptual que descrigui les variables d’interès, i després implementar-lo en un simulador per poder analitzar els resultats. ARENA és el software de simulació que s’estudia en aquest projecte i es presenta com una eina que permet la descripció complerta de l’experiència que una entitat desenvolupa a l’interior del sistema mentre flueix a través d’aquest. En concret s’utilitza la versió ARENA 10.0. Pel que fa a l’estructura del projecte, primerament s’introdueixen conceptes teòrics referents a la simulació, així com avantatges i inconvenients i els camps d’aplicació de la simulació. Seguidament i ja centrats en l’Arena, s’analitza un exemple senzill per començar-ne a veure el funcionament. Posteriorment, es van estudiant varis exemples amb complexitat progressiva. Aquests exemples es desenvolupen pas a pas de manera que es puguin anar provant amb el simulador. En el transcurs del projecte es van estudiant les eines de l’Arena i les seves possibilitats, així com els resultats obtinguts i les interpretacions d’aquests. Aquest projecte pretén, doncs, donar conceptes introductoris en el camp de la simulació en general, i, en particular, descriure eines bàsiques sobre el funcionament de l’Arena.

Projectes de modelatge i simulació avançada de sistemes mitjançant l'entorn ARENA

En l’exercici de les funcions típiques de qualsevol activitat humana, l’home ha de prendre decisions d’un o altre tipus permanentment i aquesta situació porta afegit, per lo general risc i incertesa, el que compromet la qualitat i l’èxit de la decisió. Per ajudar i contrarestar aquesta situació, l’home ha desenvolupat a través del temps una diversitat d’eines que li permeten minimitzar el risc i la incertesa en la presa de decisions. La simulació és una d’aquestes eines. Mitjançant la seva aplicació no només s’aconsegueix la comesa anterior, sinó que també es minimitzen els costos involucrats en la decisió mitjançant un millor ús dels recursos, la disminució del temps emprat per a la seva realització i la minimització de les probabilitats de risc. Aquest projecte representa la continuació d’un primer estudi introductori de la simulació anomenat: Estudi i guia docent per a modelatge i simulació de sistemes mitjançant l’entorn ARENA [9].

ContinuousMultimodal Global Optimization with Differential Evolution-Based Methods

Metaheuristic methods have become increasingly popular approaches in solving global optimization problems. From a practical viewpoint, it is often desirable to perform multimodal optimization which, enables the search of more than one optimal solution to the task at hand. Population-based metaheuristic methods offer a natural basis for multimodal optimization. The topic has received increasing interest especially in the evolutionary computation community. Several niching approaches have been suggested to allow multimodal optimization using evolutionary algorithms. Most global optimization approaches, including metaheuristics, contain global and local search phases. The requirement to locate several optima sets additional requirements for the design of algorithms to be effective in both respects in the context of multimodal optimization. In this thesis, several different multimodal optimization algorithms are studied in regard to how their implementation in the global and local search phases affect their performance in different problems. The study concentrates especially on variations of the Differential Evolution algorithm and their capabilities in multimodal optimization. To separate the global and local search search phases, three multimodal optimization algorithms are proposed, two of which hybridize the Differential Evolution with a local search method. As the theoretical background behind the operation of metaheuristics is not generally thoroughly understood, the research relies heavily on experimental studies in finding out the properties of different approaches. To achieve reliable experimental information, the experimental environment must be carefully chosen to contain appropriate and adequately varying problems. The available selection of multimodal test problems is, however, rather limited, and no general framework exists. As a part of this thesis, such a framework for generating tunable test functions for evaluating different methods of multimodal optimization experimentally is provided and used for testing the algorithms. The results demonstrate that an efficient local phase is essential for creating efficient multimodal optimization algorithms. Adding a suitable global phase has the potential to boost the performance significantly, but the weak local phase may invalidate the advantages gained from the global phase.

Resíduos de agrotóxicos em alimentos: uma preocupação ambiental global - Um enfoque às maçãs

This paper describes the use of pesticides in agriculture. Research has shown that significant quantities of pesticide residues have been found in many types of foods. Thus, an overview is given of pesticide residue determinations in fruits and vegetables, with special attention to apples. The toxicity and the adverse effects possibly caused by the exposure of these compounds are alerting the scientific community to develop studies about the validation of analytical methods for multiresidue pesticide determination in these samples. This review shows that pesticide-residue determination in apples is becoming a very important and challenging issue.

Sustainable drugs and global health care

Each day, Earth's finite resources are being depleted for energy, for material goods, for transportation, for housing, and for drugs. As we evolve scientifically and technologically, and as the population of the world rapidly approaches 7 billion and beyond, among the many issues with which we are faced is the continued availability of drugs for future global health care. Medicinal agents are primarily derived from two sources, synthetic and natural, or in some cases, as semi-synthetic compounds, a mixture of the two. For the developed world, efforts have been initiated to make drug production "greener", with milder reagents, shorter reaction times, and more efficient processing, thereby using less energy, and reactions which are more atom efficient, and generate fewer by-products. However, most of the world's population uses plants, in either crude or extract form, for their primary health care. There is relatively little discussion as yet, about the long term effects of the current, non-sustainable harvesting methods for medicinal plants from the wild, which are depleting these critical resources without concurrent initiatives to commercialize their cultivation. To meet future public health care needs, a paradigm shift is required in order to adopt new approaches using contemporary technology which will result in drugs being regarded as a sustainable commodity, irrespective of their source. In this presentation, several approaches to enhancing and sustaining the availability of drugs, both synthetic and natural, will be discussed, including the use of vegetables as chemical reagents, and the deployment of integrated strategies involving information systems, biotechnology, nanotechnology, and detection techniques for the development of medicinal plants with enhanced levels of bioactive agents.

Uso de perfis cromatográficos de voláteis de cafés arábicas torrados para a diferenciação das amostras segundo o sabor, o aroma e a qualidade global da bebida

In this work, the volatile chromatographic profiles of roasted Arabica coffees, previously analyzed for their sensorial attributes, were explored by principal component analysis. The volatile extraction technique used was the solid phase microextraction. The correlation optimized warping algorithm was used to align the gas chromatographic profiles. Fifty four compounds were found to be related to the sensorial attributes investigated. The volatiles pyrrole, 1-methyl-pyrrole, cyclopentanone, dihydro-2-methyl-3-furanone, furfural, 2-ethyl-5-methyl-pyrazine, 2-etenyl-n-methyl-pyrazine, 5-methyl-2-propionyl-furan compounds were important for the differentiation of coffee beverage according to the flavour, cleanliness and overall quality. Two figures of merit, sensitivity and specificity (or selectivity), were used to interpret the sensory attributes studied.
