Controle de qualidade em radioterapia: dosimetria de fótons em acelerador linear – Mevatron MXT

The treatment of a tumor with ionizing radiation is an ongoing process with well differentiated stages. These ones include the tumor diagnosis and location, the decision on the treatment strategy, the absorbed dose planning and calculation, the treatment administration, the absorbed dose verification and the evaluation of results in short and long terms. The quality of a radiotherapy procedure is closely linked to factors that may be classified as clinical, such as the diagnosis, the tumor location, the treatment strategy chosen and the continuous treatment reassessment; dosimetric or physical, such as the uncertainty in the dose calculation, its optimization and verification, the suitability of the equipment to provide a radiation beam consistent with the treatment planning; finally, others which are related to the practical application of radiotherapy treatment and the handling of the patient. In order to analyze the radiotherapy quality, one should realize that the three aspects (medical, physical or dosimetric and practical application) should be considered in a combined way. This means that numerous actions of the radiotherapists, medical physicists and technicians in radiotherapy should be held jointly and their knowledge level will significantly affect the treatment quality. In this study, the main physical parameters used in dosimetry are defined as well as determined experimentally for a linear accelerator Mevatron - MXT. With this, it is intended to provide recommendations for the physical aspects of Quality Assurance (QA) in the radiotherapy treatments, and these will usually be applied by professionals in Medical Physics. In addition to these instructions, it is recommended that additional texts are prepared to address in detail the clinical aspects of the treatments QA

Fatores facilitadores e restritivos no processo de gestão de franquias sob o ponto de vista do franqueado: um estudo multicasos no setor de alimentação

The present study sought to identify which are the facilitators and restrictive in the creation and management of franchises from the point of view of process factors franchisees. For this, we first proposed to critically analyze its creation and management.The specific objectives of this work are: a) to understand in the light of the theory , the basic requirements for creating franchises b ) identify, from the literature review , facilitators and restrictive factors in the process of franchise management , c) develop a survey tool to critically analyze the processes of creating and managing a franchise from the point of view of the franchisee , and d ) to review the process of creating and managing franchises , from the perspective of four franchised food services in the municipalities of Ribeirão Preto and Sao Jose do Rio Preto - SP . A descriptive qualitative work, which found the most important features about the franchises, through a study of 4 franchises in the food industry of São Paulo was performed. To complete the survey was conducted a semi-structured interview, containing questions regarding the main elements of a business: creating, planning, organization, direction and control. It was found that franchising is a business model with controversies. There are people who deal well with the system and that through him realize dreams such as owning their own business. Others need to think many times before embarking in business since the entrepreneurship factor can be so intense that it hinders the acceptance of norms and duties to the system. This causes some factors such as communication, measurement of outcomes, implementation plan and among others are considered restrictive or facilitators in the process of strategy management of franchises

Gestão ambiental aplicada a prevenção, controle e recuperação de erosão linear acelerada no município de Ipeúna-SP

The erosion is a natural process of detachment, transport and deposition of soil and rock particles from one place to another. Human activities with no previous planning may accelerate this process, causing several damages to the environment and to society. In order to control the acceleration of these erosion processes caused by humans, prevention and improvement initiatives emerge. Regarding works which interfere directly in some of the natural resources, these initiatives must respect the intrinsic physical properties of the area of interest, if they aim to obtain effective results. Based on this scenario, this work proposes a few methods of accelerated linear erosion prevention, control and recovery in a specific area of the municipal district of Ipeúna (SP). For that matter, this study is based on a method of physiographic compartmentalization of the area, considering and integrating soil, relief, geology and the use and land cover properties of the study area. Plus, a flowchart with general orientations regarding management of eroded areas was produced, focused on the control and recovery of linear erosion. The result demonstrates the importance of careful erosion control, respecting the physical properties of each physiographic unit. The vegetative and mechanical conservationists methods, and the discipline of water flow, have found wide applicability in the study area.
