Análise de portfólio de compras: estudo de caso

A importância do tema compras tem crescido dentro das empresas, à medida que estas começaram a constatar os possíveis ganhos económicos associados à melhoria dos processos de compras e das relações com os fornecedores. Isso implicou uma mudança de perspetiva, passando a encarar-se esta área como estratégica e não apenas operacional. Neste contexto, é objetivo da presente dissertação, a análise da estratégia de compras da Empresa e ao seu Portfólio de compras, com vista ao desenvolvimento de recomendações que permitam reduzir os custos com compras, tendo em conta a vertente estratégica da compra e não a vertente operacional. A metodologia usada foi o estudo de caso de uma empresa do setor alimentar adotando o Modelo de Kraljic, uma ferramenta para análise de portfólio de compras que permite recomendações estratégicas com base na categorização dos itens. Os dados foram recolhidos por intermédio de entrevistas ao Diretor de Compras da empresa em estudo bem como através da análise de documentação. Posteriormente foi analisada a política de compras, a multiplicidade de itens comprados e a base de fornecedores e as relações existentes. Os resultados permitiram verificar o desempenho da empresa ao nível das compras, esta que se encontra, na grande maioria dos itens, dependente dos fornecedores, sendo as exigências de qualidade o principal motivo dessa dependência. Foram propostas recomendações estratégicas para cada uma das famílias de itens, de modo a que possa ser mitigado o risco de abastecimento, sempre com vista á redução de custos e garantia do abastecimento.The importance of the purchasing theme has grown within businesses, as soon as the companies began to observe the possible economic gains associated with improving this department at the level of processes and relationships with suppliers. This implied a paradigm shift, with companies starting to face this area as strategic and not just as operational. It represents an evolution of the term "purchasing" for a new and broader concept, "procurement". In this context, it is the objective of this dissertation to analyze the company's purchasing strategy and its purchasing portfolio, and to develop recommendations to reduce purchasing costs, taking into account the strategic perspective of purchase and not the operational one. The methodology used was the case study and was adopted the Kaljic Model, a tool for purchasing portfolio analysis that allows strategic recommendations based on the categorization of items. The data was collected through interviews with the company's purchasing director as well as through the analysis of documentation. It was subsequently analyzed the purchasing policy, the supplier base and the existing relationships and the multiplicity of purchased items. The results have allowed to verify the company's purchasing performance, which is, for the majority of the items, dependent on the items' suppliers. The quality requirements are the main reason for this dependency. Strategic recommendations have been proposed for each of the items' families, so that the risk of supply can be mitigated, always with the purpose of reducing costs and ensuring supply

Análise global de tendências em contagens de fogos noturnos ativos (1996 - 2012)

Mestrado em Engenharia Florestal e dos Recursos Naturais - Instituto Superior de AgronomiaThis thesis aimed to perform a trend analysis of the global distribution of vegetation fires for the period from June 1996 to March 2012. We used the product from the World Fires Atlas (WFA) from the European Space Agency (ESA), obtained with the Along Track Scanning Radiometer (ATSR) sensor onboard the Second European Remote Sensing Satallite (ERS – 2), under which a filtering process was applied, following the same method of Mota et al. (2006). We conducted a comparative analysis between the initial data and the clean data and there was a percentage of false alarmes and fires that were not vegetation fires of 28%. The errors obtained were due primarily to hot surfaces and gas flares. With the data obtained, we conducted a trend analysis by performing the Mann-Kendall test in the program IDRISI Selva. The mapping created by the test, was studied to identity the presence of positive or negative trends. After a close visual study of the mapping and after the analysis of the temporal profiles of places of interest, we concluded that there is no relevant trend present globally, both positive or negative

Importância da proteção da mesa de instrumentais cirúrgicos na contaminação intraoperatória de cirurgias limpas

OBJECTIVE: to compare the degree of bacterial contamination of surgical instrument tables used in clean surgical procedures, either protected with plastic fields, sterilized with ethylene oxide, or disinfected with 70% alcohol and 1% iodine solutions. This is a randomized clinical trial in which samples were collected from the surfaces of surgical instrument tables before and after each procedure. Microbiological analysis was performed to identify microorganisms and their respective antimicrobial resistance. RESULTS: Bacterial growth in the surgeries using sterilized plastic was 5.71% before and 28.6% after surgery and, 2.9% and 45.7% respectively in surgeries using disinfection with 70% alcohol and 1% iodine solutions; no statistical difference was found between the methods. CONCLUSION: both methods present similar protection, however, 70% alcohol and 1% iodine do not generate solid waste.El objetivo del estudio fue analizar el grado de contaminación bacteriana de la mesa de instrumentos quirúrgicos en dos casos, después del uso: cubierta protectora plástico de la mesa quirúrgica esterilizada con óxido de etileno o desinfección con solución de alcohol a 70% y yodo a 1%, en procedimientos quirúrgicos limpios. Se trata de un experimento clínico aleatorio, con recolección de muestras de las superficies de las mesas de instrumentos quirúrgicos, antes y después de cada procedimiento, con posterior análisis microbiológica para identificar los microorganismos y la resistencia antimicrobiana.

A meta-analysis of biochar application to manage plant diseases caused by bacterial pathogens

The current agricultural scenario faces diverse challenges, among which phytosanitary issues are crucial. Plant diseases are mostly treated with chemicals, which cause environmental pollution and pathogen resistance. In light of the UN Sustainable Development Goals (SDGs), the biochar alternative use to chemical inputs fits into at least six of the proposed goals (2, 3, 7, 13, 15, and 17), highlighting the 12th, which explains responsible consumption and production. Biochar is valuable for inducing systemic resistance in plants because it is a practical and frequently used resource for improving physical, chemical, and biological soil attributes. This review assessed the beneficial and potential effects of applying biochar to agricultural soils on bacterial pathogen management. Such application is a recent strategy; therefore, this research evaluated 20 studies that used biochar to manage plant diseases caused by pathogens inhabiting the soil in different systems. The effectiveness of biochar application in controlling plant diseases has been attributed to its alkaline pH, which contributes to the growth of beneficial microorganisms and increases nutrient availability, and its porous structure, which provides habitat and protection for soil microbiome development. Therefore, the combined effect of improvements on soil attributes through biochar application aids pathogen control. Biochar application helps manage plant diseases through different mechanisms, inducing plant resistance, increasing activities and abundance of beneficial microorganisms, and changing soil quality for nutrient availability and abiotic conditions

Viral genetic clustering and transmission dynamics of the 2022 mpox outbreak in Portugal

Pathogen genome sequencing during epidemics enhances our ability to identify and understand suspected clusters and investigate their relationships. Here, we combine genomic and epidemiological data of the 2022 mpox outbreak to better understand early viral spread, diversification and transmission dynamics. By sequencing 52% of the confirmed cases in Portugal, we identified the mpox virus sublineages with the highest impact on case numbers and fitted them into a global context, finding evidence that several international sublineages probably emerged or spread early in Portugal. We estimated a 62% infection reporting rate and that 1.3% of the population of men who have sex with men in Portugal were infected. We infer the critical role played by sexual networks and superspreader gatherings, such as sauna attendance, in the dissemination of mpox virus. Overall, our findings highlight genomic epidemiology as a tool for the real-time monitoring and control of mpox epidemics, and can guide future vaccine policy in a highly susceptible population.info:eu-repo/semantics/publishedVersio
