    TCC(graduação) - Universidade Federal de Santa Catarina. Centro Tecnológico. Engenharia de ProduçãoAs micro e pequenas empresas correspondem à grande maioria dos empreendimentos, sendo responsáveis por gerar a maior parte dos empregos com carteira assinada no Brasil. Entretanto, quase metade dessas empresas fecham antes de completarem 2 anos de vida, e um dos principais motivos está relacionado à falta de planejamento estratégico nesses negócios. Dentro desse contexto, este trabalho tem como finalidade elaborar o planejamento estratégico de uma micro empresa de culinária japonesa, por meio do uso de técnicas e ferramentas desenvolvidas por autores renomados da área. Este estudo visa auxiliar a empresa a aumentar sua competitividade, direcionando seus recursos e esforços através de princípios estratégicos. A metodologia de implementação do planejamento estratégico usada neste trabalho propõe 4 etapas: diagnóstico estratégico, missão da empresa, instrumentos prescritivos e quantitativos e controle e avaliação. Os resultados ao final do trabalho destacam a receptividade da empresa quanto à aplicação da metodologia proposta.According to SEBRAE, micro and small companies correspond to the vast majority of enterprises, being responsible for generating majority of jobs with a formal contract in Brazil. However, about almost half of these enterprises go out of business before the first 2 years of operation, and one of the main reasons is the lack of strategic planning in these businesses. Within this context, this paper aims to elaborate the strategic planning of a Japanese cooking company, with techniques and tools developed by renowned authors of the area. This study aims to help the company increase its competitiveness by directing its resources and efforts through strategic principles. The strategic planning implementation methodology used in this work proposes four steps: strategic diagnosis, company mission, prescriptive and quantitative instruments and control and evaluation. The results of the work highlight the receptivity of the company regarding the application of the proposed methodology

    Jointly Exploring Client Drift and Catastrophic Forgetting in Dynamic Learning

    Federated and Continual Learning have emerged as potential paradigms for the robust and privacy-aware use of Deep Learning in dynamic environments. However, Client Drift and Catastrophic Forgetting are fundamental obstacles to guaranteeing consistent performance. Existing work only addresses these problems separately, which neglects the fact that the root cause behind both forms of performance deterioration is connected. We propose a unified analysis framework for building a controlled test environment for Client Drift -- by perturbing a defined ratio of clients -- and Catastrophic Forgetting -- by shifting all clients with a particular strength. Our framework further leverages this new combined analysis by generating a 3D landscape of the combined performance impact from both. We demonstrate that the performance drop through Client Drift, caused by a certain share of shifted clients, is correlated to the drop from Catastrophic Forgetting resulting from a corresponding shift strength. Correlation tests between both problems for Computer Vision (CelebA) and Medical Imaging (PESO) support this new perspective, with an average Pearson rank correlation coefficient of over 0.94. Our framework's novel ability of combined spatio-temporal shift analysis allows us to investigate how both forms of distribution shift behave in mixed scenarios, opening a new pathway for better generalization. We show that a combination of moderate Client Drift and Catastrophic Forgetting can even improve the performance of the resulting model (causing a "Generalization Bump") compared to when only one of the shifts occurs individually. We apply a simple and commonly used method from Continual Learning in the federated setting and observe this phenomenon to be reoccurring, leveraging the ability of our framework to analyze existing and novel methods for Federated and Continual Learning

    Este trabalho analisa um elevador de canecas, estruturando um método de cálculo para dimensionamento deste equipamento, a partir de metodologias atuais empregada na indústria, e então comparando seus resultados previstos. Os cálculos, escritos em código VBA, para possibilitar a geração de resultados instantâneos e seguros, dão a liberdade de modificar variáveis de entrada e avaliar os diferentes resultados obtidos, para então compará-los. Com a construção de um protótipo é avaliado o método de dimensionamento e validado sua eficácia para projetar um elevador funcional com descarga centrífuga. Com isto contribui-se para um refinamento dos cálculos de previsão teórica e analisa-se a prática construtiva e os efeitos sinergéticos das variáveis envolvidas na descarga do elevador. Assim, é possível averiguar a compatibilidade entre os resultados teóricos e experimentais para aproximar os resultados previstos pelo projeto com a realidade economizando-se na construção de equipamentos similares.This study analyzes a bucket elevator, setting the equations required to create a method of calculation to dimensioning of this equipment with current methodologies employed in the industry and compares the results. The calculations, written in VBA code, enable a generation of fast and safe results. With this procedure, there is independence to modify the input variables and evaluate the different results obtained, and then compare them. With the construction of a prototype the dimensioning method is evaluated, and its effectiveness validated for designing a functional centrifugal discharge elevator. This contributes to a refinement of the theoretical calculations, analyzes the constructive practice and allows seeing the synergistic effects of the variables involved in the lift discharge. Thus, it is possible to verify the compatibility between the theoretical and experimental results in order to bring the projected results closer to the reality as for improving the used methodology and lowering costs on the construction of similar equipment

    La presente investigación tuvo como objetivo establecer la diferencia en la Insatisfacción con la Imagen Corporal entre estudiantes mujeres de una Universidad Particular y una Universidad Estatal de la ciudad de Trujillo. El tipo de investigación, según su finalidad es de carácter práctico, debido a que hace uso de una teoría para solucionar un determinado problema; según su naturaleza es cuantitativa, dado que hace uso de procedimientos estadísticos; según su carácter es descriptiva comparativa, porque posee una variable y dos poblaciones de las cuales se intentan demostrar sus diferencias. Para la recolección de información durante el proceso de investigación se utilizó el Test de Imagen de Garcia (2013), el cual consta de tres dimensiones: cognitivo – emocional, perceptiva y comportamental, se aplicó en una muestra de 60 estudiantes universitarias. Finalmente, la investigación tuvo como resultado que no existe diferencia en la Insatisfacción con la Imagen Corporal entre estudiantes mujeres de una Universidad Particular y Estatal de la ciudad de Trujillo, debido a que la Insatisfacción con la Imagen Corporal se caracteriza principalmente por la presencia de juicios valorativos sobre el propio cuerpo que no coinciden con la realidad y características reales

    Mediante el presente artículo se analizarán los principios de tutela judicial efectiva y sostenibilidad fiscal existen en Colombia y se relacionan creando armonía en la producción de fallos de las altas cortes. Lo anterior, teniendo como referencia los diferentes procesos administrativos mediante los cuales los sujetos procesales actúan y se desenvuelven judicialmente para la protección de sus derechos. El legislador aclara que, en el momento de la expedición de sus fallos, se debe dar debida protección a los derechos de cada una de las partes procesales teniendo en cuenta que invocar el principio de sostenibilidad fiscal por parte de la administración seria ir en contra de dicha protección. En consecuencia, este trabajo de investigación busca responder a las preguntas: ¿Se genera alguna afectación a los derechos de los sujetos procesales invocar el principio de sostenibilidad fiscal a la hora de proferir fallos? Y ¿Cuál es el papel del bloque de constitucionalidad en dicho procedimiento administrativo? La Constitución Política de Colombia de 1991 (en su artículo 93), provee la cláusula de inclusión de normas de carácter internacional como lo son tratados suscritos y ratificados por la Nación para la protección de derechos humanos como en repetidas ocasiones se ha indicado que es la tutela judicial efectiva. Palabras claves: Sostenibilidad fiscal, Bloque de Constitucionalidad, incidente de Impacto Fiscal y Tutela Judicial Efectiva.Universidad Libre-- facultda de Derecho -- Especialización Derecho AdministrativoThrough this article, the principles of effective judicial protection and fiscal sustainability will be analyzed in Colombia and are related creating harmony in the production of rulings of the high courts. The foregoing, having as reference the different administrative processes through which the procedural subjects act and develop judicially for the protection of their rights. The legislator clarifies that at the time of issuing its rulings, due protection must be given to the rights of each of the procedural parties, taking into account that invoking the principle of fiscal sustainability by the administration would be going against said protection. Consequently, this research work seeks to answer the questions: Does it generate any affectation to the rights of the procedural subjects to invoke the principle of fiscal sustainability when making rulings? And what is the role of the constitutional block in said administrative procedure? The Political Constitution of Colombia of 1991 in its article 93, provides the clause of inclusion of international norms such as treaties signed and ratified by the Nation for the protection of human rights as it has been repeatedly indicated that it is judicial protection. effective
