Uso de ambientes virtuais para a simulação de acidentes radiológicos / Use of virtual environments to simulate radiological accidents

Tadeu Augusto de Almeida Silva 26 June 2012 (has links)
Em um ambiente virtual, construído com o uso de tecnologia computacional, encontram-se presentes entidades virtuais inseridas em um espaço tridimensional, que é utilizado para a simulação de processos críticos, como os acidentes radiológicos. A pronta detecção de um acidente radiológico e a determinação da sua possível extensão são fatores essenciais para o planejamento de respostas imediatas e de ações de emergência. A integração das representações georeferenciadas do espaço tridimensional, com modelos baseados em agentes autônomos, com o objetivo de construir ambientes virtuais que tenham a capacidade de simular acidentes radiológicos é a proposta dessa tese. As representações georeferenciadas do espaço tridimensional candidatas são: i)as representações espaciais usadas nos sistemas de informações geográficas (SIG) e ii) a representação adotada pelo Google MapsTM. Com o uso deste ambiente pode-se: quantificar as doses recebidas pelas pessoas; ter uma distribuição espacial das pessoas contaminadas; estimar o número de indivíduos contaminados; estimar o impacto na rede de saúde; estimar impactos ambientais; gerar zonas de exclusão; construir cenários alternativos; treinar pessoal técnico para lidar com acidentes radiológicos. / In a virtual environment, built with the use of computer technology, there are virtual entities, inserted into a virtual three-dimensional space, which is used to simulate critical processes, such as radiological accidents. Early detection of a radiological accident and determining its possible extension are essential for planning an immediate response and emergency actions. The purpose of this thesis is to build virtual environments that have the ability to simulate radiological accidents. These virtual environments are based on the integration of georeferenced representations of the three dimensional space with autonomous agents-based models. The georeferenced representations candidates are: i) the spatial representation used in geographic information systems (GIS); ii) the representation adopted by Google MapsTM. Using these virtual environments, in case of occurrences of radiological accidents, it will be possible to quantify the doses received by people, have a spatial distribution of infected persons; estimate the number of infected individuals; estimate the impact on the health network, estimate environmental impacts, generate exclusion zones, building scenarios alternative; train staff for dealing with these accidents.

Učební pomůcka při chemické havárii / Teaching tool in case of chemical accident

GAIGEROVÁ, Petra January 2017 (has links)
Learning programs using simulation technologies are not just a suitable form of replacement for classical textbooks. They are a brand new teaching aid using Jan Amos Komenský's old motto "Schola Ludus" is a school game. The combination of a virtual and realistic environment with simulation models enables students to visually explore the possibilities of dealing with an emergency situation. One of the projects implemented by the non-governmental nonprofit organization Center for Safe State Project Software Applications 3D simulator. The motivation for choosing the topic of my thesis is that I have been working as the head of a laboratory in a chemical plant for several years. One of the main activities is the transport of dangerous chemicals by road and rail, or operations related to packaging, loading, filling and unloading of such chemicals. My daily activity is responsible for preventing the occurrence of undesirable risks with regard to the protection of persons, property and the environment. To create a textbook for 3D simulator and consequently to use it in the framework of teaching was the main aim of this work. It is important to realize that dangerous substances can escape almost at any moment, so it is necessary to create conditions for the prevention of these events. The success of this area is mainly a good, systematic and coordinated preparation of decisive activities. The diploma thesis is divided into two parts. The theoretical part briefly summarizes the basic knowledge and information about the given issue. There are described the most commonly used software tools and their use for teaching. I deal with the model solution of the accident in the transport of dangerous substances in the practical part, the scenario being created includes a description of the activities that are involved in the management and solution of an emergency. This knowledge was subsequently used to create learning text.

Potřeby pacientů po poškození mozku / The Needs Of Patients After Brain Damage

PECHOUŠKOVÁ, Kateřina January 2017 (has links)
This diploma thesis is a part of the GAJU project entitled "Coordinated rehabilitation of patients with brain injury (reg. number GAJU 128/2016/S)". At the time when the thesis was elaborated, only the patients who suffered the cerebrovascular accident were engaged in the project, since in the hospital, no suitable patient after brain injury who would need a multidisciplinary team in home care had ever been sought. The selection of the patients was based on the communicative skills criteria e.g. if the skills to participate in the directed conversation based on the Functional Independence Measure Questionnaire (FIM), WHO Disability Assessment Schedule 2.0 and the follow-up questions concerning social issues, physiotherapeutic methods and techniques were preserved. Within the framework of the project, the research has not been finished yet. Given the above mentioned reasons, this thesis is therefore mainly focused on the identification of patients' needs after the cerebrovascular accident (CVA), on the period starting from its first incidence during the first three months period after the discharge from the hospital to home care. The complex results will be presented as a part of the publication activity of the project. The thesis comprises a theoretical and a practical part. The theoretical part presents a comprehensive view on the care for the patients who suffered the cerebrovascular accident. I addressed both the basic characteristics of the cerebrovascular accident and the organisation of the care for the patients in the Czech Republic; furthermore, the coordinated rehabilitation team, the role of a social worker, possibilities of social help provided by the welfare system to patients and their families, and the psychical condition of the patient. In the last chapter, I outline the general concept of human needs according to A. Maslow and describe important needs of the sick people. As far as the research part is concerned, my goal is to identify the needs of patients in home care after the brain injury. In connection with the aim of the thesis, two research questions were defined. The first question is: "What are the needs of the patients after brain injury?". The second question is: "What is the role of a social worker in meeting the needs of a patient with brain injury?" The qualitative research strategy was used; the instructional dialogue technique with patients after brain injury in the South Bohemia Region within the project. When analyzing the data collected from the patients during the first three months after the discharge from the hospital to the home care, seven major patient needs emerged need of help, need of psychical equilibrium, need of self-reliance, need of being without paint, need of recovering to the condition before CVA incidence, and need of establishing a new system of activities. Two of these needs, the need of recovering to the condition before CVA incidence and the need of establishing a new system of activities could be considered as principal, because the other needs are in general heading towards them. Furthermore, the analysis of the results showed the role of a social worker by means of which these needs can be saturated The results of the present thesis are used as a partial part from which the complex results of coordinated rehabilitation of patients after brain injury of the GAJU project are complied. The needs analysis of patients brought the proposals of dealing with/saturation of these needs and therefore had a direct impact on the lives of the respondents. The results of the research will become a part of the publication outputs of the above-mentioned projects.

Formalismy kvantové a relativistické fyziky při zkoumání příčin mimořádných událostí / Formalisms of quantum and relativistic physics in exploring the causes of emergencies

JANOŠÍKOVÁ, Martina January 2018 (has links)
Currently emergencies coming from different reasons and are caused by various factors. In my diploma thesis is focusing on the causes of emergencies coming from quantum and relativistic physics. Among such emergencies are the ligting and the radiation accident. Lightning causes fires in the landscape and its light identification can be explained by the quantum mechanics of the photon, the wave-particle duality of the photon. In the case of a radiation accident occur radioactivity and ionizing radiation. This leakage can be described using the special theory of theory of relativity. On the basis of this informationwas created an educational text that was adapted to the capabilities of students of Civil crisis preparedness.

Eliane Maria Gorga Lago 28 March 2006 (has links)
Dentro da cadeia produtiva da Construção Civil a segurança busca na prevenção seu enfoque principal, realizando sempre intervenções através das correções dos erros, das falhas e não conformidades do processo e da legislação evitando assim, as conseqüências que podem representar o acidente. Os custos dos acidentes podem ser de grandes proporções ou, até mesmo, incalculáveis, visto que a vida humana não tem preço. Assim sendo através disso as empresas passam a acreditar que a competitividade e o lucro não são os elementos fundamentais para a sua organização e demonstram através da busca da melhoria contínua de seus processos a preocupação com as questões da segurança do ambiente de trabalho. O objetivo desta pesquisa é desenvolver o Sistema de Gestão de Segurança e Saúde do Trabalho SGSST para empresas da indústria a construção civil, neste segmento, 98,28% possuem até 99 (noventa e nove) empregados segundo dados do Ministério do Trabalho Emprego MTE, tomando-se como base as Diretrizes da Organização Internacional do Trabalho OIT sobre Sistemas e Gestão da Segurança e Saúde no Trabalho. O SGSST proposto foi implantado, aplicado e monitorado em uma empresa de construção civil no estado de Pernambuco. Os resultados obtidos nos mostram uma significativa redução das situações de riscos de acidentes gerando uma melhora direta nas condições do ambiente de trabalho, instituindo uma nova cultura dentro da empresa através das ações preventivas, garantindo que a implementação do sistema de gestão de segurança do trabalho pode trazer melhorias ao sistema produtivo com produtividade. / Safety in the productive chain of Civil Engineering Construction focuses on prevention, intervening through the correction of errors, imperfections, and non-conformity of processes and legislation, thereby preventing consequences that can lead to an accident. The costs of these accidents can be enormous or even incalculable, considering that a human life is priceless. Companies are beginning to realize that competitiveness and profit are not the most important elements of their organization and have demonstrated through the implementation of continuous process improvement their concern with the issue of safety in the work environment. The objective of this research is to develop an Occupational Safety and Health Management System (SGSST) for small civil construction companies, which, according to the Ministry of Work and Employment (MTE), have less than 100 employees and represent 98.28% of workers in the civil construction industry, using as a base the Directives of the International Work Organization (OIT) on Occupational Safety and Health Management Systems. To evaluate the proposed SGSST, it was implanted, applied and monitored in a civil construction company located in the state of Pernambuco. The results obtained indicate significant improvements in work environment conditions, creating a new culture within the company, through the use of preventive actions. During the implantation of the system, there was a reduction of risk of work-related accidents, guaranteeing that the implementation of the occupational safety and health management system can bring significant improvements to the productive system with productivity.

Objectives: evaluating the health-related quality of life of family caregivers of patients with sequelae with CVA. Methods: the research was descriptive, transversal type, with a quantitative approach, held at the domicile of patients with sequelae by AVE, in the city of João Pessoa-Paraíba, in the period between the months of February and April 2013. The population of the study consisted of 136 family caregivers of patients affected by stroke. For data collection, there was used a structured instrument, contemplating closed issues relating to variables of the study and the specific measures to assess, respectively, the physical capacity of individuals with sequel by CVA, the overload and health-related quality of life among caregivers: Barthel index, Burden Interview Scale and Short Form-36. The analysis was performed using three techniques: statistical descriptive analysis and exploratory data analysis and Association through the Chi-square test and the T-test and F for comparisons of the averages. The project was submitted to the ethics committee of the Centre for Health Sciences, Federal University of Paraíba Health and approved under protocol number 0279/13 and CAAE: 13778313.3.0000.5188. Results: commitment was evidenced in almost all domains of quality of life of family caregivers, among them, those who were presented with lower average were: Pain (40.16), Mental Health (53.62) and Social Aspects (54.12). Characteristics of individuals with sequel by CVA, which is related with the domains of quality of life, one can find out that those who were below the age of 65, were married and had highest level of schooling, major averages, respectively, in the fields of Social Aspect, Emotional and Mental Health Aspects. Caregivers of people with higher level of dependency to the basic activities of daily living had lower average in the mental health field. Regarding the characteristics of the caregiver, major averages were caregivers under the age of 40 years old and married in the field, Functional Capacity, those who had a profession, on emotional aspects and those who had higher income, in the areas of mental health and vitality. There was also an association between overload and worse health-related quality of life in the areas of functional capacity, physical aspects, emotional aspects and Pain. Conclusion: the results of the study allowed understanding the different dimensions and specificities in the context of the health-related quality of life, evidencing the need for redirection of the look to public spheres for the recognition of the problems faced by the family when individuals are affected by a disabling disease, such as CVA. / Introdução: As sequelas físicas e cognitivas provocadas pelo AVE comprometem a capacidade funcional, a independência e a autonomia da pessoa acometida e acarreta alterações na dinâmica de vida não só do indivíduo acometido, mas também da família, sobretudo na do cuidador principal. Objetivos: Avaliar a qualidade de vida relacionada à saúde de cuidadores familiares de pacientes com sequelas com AVE. Metodologia: A pesquisa foi do tipo descritivo, transversal, com abordagem quantitativa, realizada no domicílio dos pacientes com sequela de AVE, no município de João Pessoa PB, no período de fevereiro a abril de 2013. A população do estudo foi composta por 136 cuidadores familiares de pacientes acometidos por acidente vascular. Para a coleta dos dados, foi utilizado um instrumento estruturado, contemplando questões fechadas relativas às variáveis do estudo e às medidas específicas para avaliar, respectivamente, a capacidade física dos indivíduos com sequela de AVE, a sobrecarga e a qualidade de vida relacionada à saúde entre os cuidadores: índice Barthel, Burden Interview Scale e o Short-Form-36. A análise foi realizada através de três técnicas: estatísticas: Análise Descritiva e Exploratória de Dados e Análise de Associação por meio do Teste de qui-quadrado e o Teste T e F para comparações das médias.

It is possible that the demonstration using videotapes or photographs of movements that will be learned can assist the codification, classification and reorganization of the elements of the task in familiar diagrams and thus facilitate the process of motor rehabilitation. The aim of this study was to analyze the performance in the test of recognition of sequences of functional activities such as water drinking and hair combing presented partially (by photos) and completely (by video) to the patients with encephalic vascular accident . The sample was generated from 12 patients (62 ? 8 years) and 10 healthy subjects (53 ? 5 years), of both sex, divided in two groups for which 5 functional activities were presented partially and completely, in 4 sequences that varied between reached and not reached objectives and correct and incorrect movements, during 24 trials. The test t'Student was applied to verify differences in the recognition time between the groups, and to compare the performance between the tests carried through at 9:00 am and retests at 9:00 am and 4:00 pm. To compare the frequency between the types of reply, the test Qui-square was used. It was verified that the patients presented a greater recognition time and a lower number of correct answers than the healthy subjects, and had better performances in the recognition of the complete sequence than the partial one. Bigger frequency was observed in the reply that the objective and the movement were being presented correctly, however the healthy subjects had soon indicated the correct reply in the first trials. An improvement tendency was observed in the performance, when the stages of tests and retests had been carried through in the same schedule. According to the results, it is suggested that the patients with stroke can better recognize the correct movements of a functional activity when it is presented completely in video form, what can influence the choice of the therapeutical strategy during the process of motor rehabilitation / Durante a reabilita??o motora de pacientes com patologias neurol?gicas, existem muitos fatores que interferem no processo terap?utico. ? poss?vel que a demonstra??o utilizando videoteipes ou fotografias de movimentos a serem aprendidos possa auxiliar a codifica??o, classifica??o e reorganiza??o dos elementos da tarefa em esquemas familiares e assim facilitar o processo de reaprendizagem motora.

Uso de ambientes virtuais para a simulação de acidentes radiológicos / Use of virtual environments to simulate radiological accidents

Tadeu Augusto de Almeida Silva 26 June 2012 (has links)
Em um ambiente virtual, construído com o uso de tecnologia computacional, encontram-se presentes entidades virtuais inseridas em um espaço tridimensional, que é utilizado para a simulação de processos críticos, como os acidentes radiológicos. A pronta detecção de um acidente radiológico e a determinação da sua possível extensão são fatores essenciais para o planejamento de respostas imediatas e de ações de emergência. A integração das representações georeferenciadas do espaço tridimensional, com modelos baseados em agentes autônomos, com o objetivo de construir ambientes virtuais que tenham a capacidade de simular acidentes radiológicos é a proposta dessa tese. As representações georeferenciadas do espaço tridimensional candidatas são: i)as representações espaciais usadas nos sistemas de informações geográficas (SIG) e ii) a representação adotada pelo Google MapsTM. Com o uso deste ambiente pode-se: quantificar as doses recebidas pelas pessoas; ter uma distribuição espacial das pessoas contaminadas; estimar o número de indivíduos contaminados; estimar o impacto na rede de saúde; estimar impactos ambientais; gerar zonas de exclusão; construir cenários alternativos; treinar pessoal técnico para lidar com acidentes radiológicos. / In a virtual environment, built with the use of computer technology, there are virtual entities, inserted into a virtual three-dimensional space, which is used to simulate critical processes, such as radiological accidents. Early detection of a radiological accident and determining its possible extension are essential for planning an immediate response and emergency actions. The purpose of this thesis is to build virtual environments that have the ability to simulate radiological accidents. These virtual environments are based on the integration of georeferenced representations of the three dimensional space with autonomous agents-based models. The georeferenced representations candidates are: i) the spatial representation used in geographic information systems (GIS); ii) the representation adopted by Google MapsTM. Using these virtual environments, in case of occurrences of radiological accidents, it will be possible to quantify the doses received by people, have a spatial distribution of infected persons; estimate the number of infected individuals; estimate the impact on the health network, estimate environmental impacts, generate exclusion zones, building scenarios alternative; train staff for dealing with these accidents.
