The Independent Influence of Large Differences in Adiposity on Thermoregulatory Responses during Exercise

Dervis, Sheila January 2014 (has links)
Currently no previous study has isolated the independent influence of body fat (BF) on thermoregulatory responses from the confounding biophysical factors of body mass and metabolic heat production (Hprod). Therefore, seven lean (L, BF:10.7 ± 4.1%) and seven non-lean (NL, BF:32.2 ± 6.4%) males matched for total body mass (TBM, L: 87.8 ± 8.5 kg, NL: 89.4 ± 7.8 kg; P= 0.73), cycled for 60 min in a 28.2 ±0.2˚C and 27 ± 10% RH room at i) a Hprod of 546 W; and ii) a Hprod of 7.5 W·kg lean body mass (LBM). Rectal (Tre) and esophageal (Tes) temperatures, and local sweat rate (LSR) were measured continuously; while whole body sweat loss (WBSL) was measured from 0-60 mins. At 546 W, changes in Tre (L: 0.74 ± 0.16ºC, NL: 0.83 ± 0.14ºC), mean local sweat rate (MLSR) based on an average of upper-back and forearm local sweat rates (L: 0.65 ± 0.25, NL: 0.59±0.12 mgcm-2min-1) and WBSL (L: 568 ± 28 mL, NL: 567 ± 29 mL) were similar (P>0.58). At 7.5 W·kg LBM, the L group had greater changes in Tre (L: 0.87 ± 0.16ºC, NL: 0.55 ± 0.11ºC), MLSR (L: 0.83 ±0 .38, NL: 0.41 ± 0.13 mgcm-2min-1) and WBSL (L: 638 ± 19 mL, NL: 399 ± 17 mL) (P<0.05). In conclusion, i) body fat does not independently alter thermoregulatory responses during exercise; ii) core temperature comparisons between groups differing in BF should be performed using a Hprod normalized for TBM, not LBM.

Specifika úrovně štíhlosti ve vybrané společnosti / Specifika úrovně štíhlosti ve vybrané společnosti

Lesňák, Martin January 2015 (has links)
The Lean concept arises from Toyota Production Syste (TPS). Then, the concept of leanness includes Value, Waste and Continuous Improvement. An organization with high level of leanness creates higher value to customers with lower level of waste within a continuous improvement environment. The examination of these diploma theses determines a new approach of lean measurement. Although, the use of ethnography is new in Lean management, it opens new possibilities to understand the behavior of the people about the organizational leanness.

No. of bitstreams: 1 Alceu Antonioli Filho.pdf: 1259303 bytes, checksum: ea7f3b6b4ead8b23c2f7f1cce4f0bfbd (MD5) Previous issue date: 2015-02-10 / The pursuit for an efficient productive process, low costs and higher value added for products and services offered to the customers has become an important feature for companies in various economic sectors in a global perspective. In the service sector, some companies have adopted the fundamentals of Lean Service to eliminate waste in many aspects of their activities aiming better operating results. However, the lack of knowledge in this sector and the low number of research in adoption of Lean Service, require studies on their applicability. This research aimed to check if the Lean Service practices are applied to Information Technology (IT) services activities and if this has brought improvements in operational terms as well as in the quality of services provided. A systematic literature review supported by bibliometrics methods identified just few articles published in this area into literature however this research identified some companies using it in this sector. In an empirical perspective of LS application two case studies present results with evidence of operating performance and quality improvements on LS practices adopted relating the previous environment. / A busca por um processo produtivo eficiente de baixo custo e maior valor agregado aos produtos e serviços oferecidos aos clientes se tornou uma característica importante para empresas de diversos setores econômicos em uma perspectiva global. No setor serviços, algumas empresas adotaram os fundamentos do Lean Service para eliminar os desperdícios em vários aspectos de suas atividades visando melhores resultados operacionais. Entretanto, a falta de conhecimento neste setor e a baixa quantidade de investigações sobre a adoção do Lean Service demandam estudos sobre sua aplicabilidade. Neste contexto, o trabalho buscou constatar se as práticas do Lean Service são aplicadas nas atividades de serviços de Tecnologia da Informação (TI) e se isso trouxe melhorias em termos de desempenho operacional, bem como, na qualidade dos serviços prestados. Uma revisão sistemática de literatura apoiado com técnicas bibliométricas aponta escassez de artigos publicados nesta área na literatura, entretanto um levantamento realizado nesta pesquisa indica sua utilização por diversas empresas do setor. Para uma perspectiva empírica da aplicação do LS, dois estudos de caso apresentam resultados com evidências de melhorias no quesito de desempenho operacional e qualidade em relação ao ambiente previamente às práticas do LS adotadas.

Espinoza Ruffner, Sergio, Gutiérrez Vega, Raúl, Sánchez Rengifo, Fernando 05 1900 (has links)
Este plan de negocio se basa en que la empresa Bestcon S.A.C. mejore el flujo de procesos y eficiencia de recursos para entregar servicios personalizados al cliente, en el tiempo esperado y a un costo por debajo promedio del mercado. Para lograr esto, se plantea el uso de la metodología Lean Construction, cuyo principio fundamental es la reducción de pérdidas en las actividades de construcción y maximizar la rentabilidad del proyecto. Es importante indicar que gran parte de las pequeñas y medianas empresas utilizan la metodología tradicional para brindar sus servicios, lo cual consiste en la falta de planificación de sus actividades y únicamente entrar donde hay espacio, sin tener clara la posibilidad de optimizar sus recursos. Es así como el uso de esta metodología (Lean Construction), genera una oportunidad de negocio. Parte del estudio realizado, es determinar el grado de rivalidad de los competidores en el mercado de implementación de oficinas, es así, que se comprobó la fragmentación del mercado de implementación de oficinas, es decir, compiten muchas empresas, pero ninguna tiene gran participación en el mercado. Por este motivo, es necesario agrupar el mercado por líneas de negocio y centrarse en empresas que brinden servicios similares o iguales con una estrategia basada en costos. Los clientes potenciales serán empresas de manufactura, logística, consumo masivo, informática y telecomunicaciones, que se encuentren buscando nuevas ubicaciones para trasladar sus oficinas administrativas, mayormente en los distritos de Surco, La Molina y Magdalena del Mar.

Teniendo en cuenta la demanda actual de viviendas en el Sector A en Lima Metropolitana, así como la aplicación de diferentes metodologías en el sector construcción con el propósito de desarrollar proyectos dentro del costo, tiempo y de calidad planeados, es que se ha tomado como objeto de estudio el proyecto de construcción de un edificio de vivienda bifamiliar del sector A, con un plazo de ejecución de 6 meses, considerando un alcance de construcción hasta la etapa Casco y en la modalidad de Suma Alzada. El objetivo del presente trabajo de investigación es desarrollar un planeamiento específico para proyectos de vivienda en el sector A en un tiempo reducido para minimizar los sobrecostos y cumplir con el plazo de obra. Por tal motivo, se han identificado los problemas suscitados durante la construcción de la obra, entre los que se encuentran las incompatibilidades del proyecto, inadecuado planeamiento, cambios en el diseño, cambios de alcance y retrabajos en obra. Seguidamente se ha diagnosticado la repercusión de estos problemas en el presupuesto meta, plazo de ejecución y calidad de la edificación, para finalmente elaborar un plan de acción en donde se presenta de manera detallada el Organigrama de obra, el EDT y Cronograma de obra, Modelado y sectorización, gestión de riesgos y cambios aplicados al proyecto y por último un Diagrama de Pareto aplicado al presupuesto meta. Finalmente se realiza la evaluación del costo de implementación del plan de acción con el propósito de que se pueda ser aplicable a otras construcciones de similares características. / Taking into account the current demand for housing in Sector A in Metropolitan Lima, as well as the application of different methodologies in the construction sector with the purpose of developing projects within the planned cost, time and quality, is that it has been taken as a study object the construction project of a two-family housing building in Sector A, with an execution time of 6 months, considering a scope of construction until the Casco stage and in the modality of “Suma Alzada”. The objective of this research work is to develop a specific planning for housing projects in sector A in a reduced time to minimize cost overruns and meet the construction deadline. For this reason, the problems that have arisen during the construction of the work have been identified, among which are the incompatibilities of the project, inadequate planning, changes in design, changes in scope and rework on site. Next, the repercussion of these problems on the target budget, execution time and quality of the building was diagnosed, and finally an action plan was drawn up, in which the work organization chart, the WBS and work schedule, modeling and sectoring, risk management and changes applied to the project were presented in detail, and finally a Pareto diagram applied to the target budget. Finally, the cost of implementing the action plan is evaluated so that it can be applied to other constructions of similar characteristics. / Trabajo de investigación

Propuesta de mejora en el proceso productivo de una empresa fabricante de películas plásticas para empaques flexibles / Improvement proposal in the production process of a manufacturing plastic films for flexible packaging company

Silva Reyes, Alfredo Jeampiere 09 January 2020 (has links)
El presente proyecto sobre el proceso de producción de películas plásticas nos muestra el problema del incremento de devoluciones de productos de una empresa que produce películas plásticas para empaques flexibles. Entre los factores que generan el incremento de devoluciones de productos de la empresa están los defectos de los films por la mala manipulación de materiales y, sobre todo, por el punto duro en las bobinas a causa del tiempo excesivo de setup de la extrusora haciendo que el cabezal se caliente y la extrusión no sea pareja. La extrusión es un proceso clave para la producción de los materiales plásticos; puesto que, transforma el polipropileno y los aditivos en láminas plásticas. Este retraso en los tiempos de preparación de la maquinaria por parte de los operarios genera el sobrecalentamiento del cabezal y; por lo tanto, productos defectuosos en la siguiente línea de producción que son devueltos a la empresa por los clientes. Con la finalidad de enfrentar este problema se desarrolla una propuesta utilizando la herramienta SMED de Lean Manufacturing para disminuir el tiempo de preparación de la extrusora y aumentar la productividad de la empresa. Para la validación de la propuesta se simula el sistema y la reducción del tiempo en el proceso de preparación de la máquina extrusora para el cambio de producción. / The present project show the problem of an increase in product returns for a company that produces plastic films for flexible packaging. Among the factors that have resulted in the increase of returned products are defects in the films caused by the poor manipulation of materials and, above all, the hard point in the coils caused by excessive extruder preparation time, causing the extrusion head to overheat as well as uneven extrusion. Extrusion is a key process in the production of plastic materials as it transforms polypropylene and additives into plastic sheets. The delay in the preparation time caused by machine operators leads to the overheating of the extrusion head and, therefore, defective products that are ultimately returned to the company by customers. In order to confront this problem, a proposal was developed using the SMED tool of Lean Manufacturing in order to reduce the preparation time of the extruder and to increase the productivity of the company. For the validation of the proposal, we simulated the system to determine the resulting reduction in extruder preparation time. / Trabajo de Suficiencia Profesional
