Le but de notre travail était d’évaluer l’impact des rythmes biologiques et psychologiques sur l’activité opérationnelle des sapeurs-pompiers (SP). La 1ère partie de notre étude se base sur une analyse des bases de données opérationnelles du SDIS 71. Le profil circadien du lag time (LT), durée existante entre l’appel et le départ du véhicule de secours pour arrêt cardiaque extra hospitalier (ACEH), ainsi que le profil horaire du risque relatif des accidents en intervention des SP (AIRR, tenant compte du nb de SP par intervention et par unité de temps), ont été étudiés sur 4ans. Une variation circadienne montrant un pic nocturne a été validée pour le LTACEH ainsi que pour l’AIRR. La stabilité du LTACEH et sa faible corrélation avec le rythme des ACEH favorisent l’hypothèse d’une origine endogène. De plus, pour une seule et même population de SP, le profil circadien du LTACEH est corrélé positivement à celui des AIRR: l’hypothèse d’une variation de performance corrélée à celle des accidents semblait donc validée. La 2ème partie s’est intéressée aux différences individuelles entre les τ de 16 rythmes de 30 SP du SDIS 71, de moyenne d’âge, de BMI, de chronotype, et d’expériences comparables. Les mesures ont été recueillies pendant 8j en hiver et en été. Le taux de désynchronisation (TD = nb variable τ≠24.0h / nb variables étudiées x100) a servi à confirmer la coexistence d’oscillateurs circadiens souples et robustes, dont le gradient définit les différences interindividuelles dans le TD des SP. Ces différences sont cohérentes avec l’hypothèse d’une origine héritée de la propension à la désynchronisation des SP. Elles pointent également le fait que, malgré les creux nocturnes d’AIRR et du LTACEH, les rythmes de la performance sont inexistants pour la majeure partie des SP étudiés, réfutant l’hypothèse d’un lien unique existant entre rythme de la performance et rythme des accidents. Ces résultats mettent en perspective de nouvelles explications du phénomène du black time. Ici, le pattern circadien d’AIRR semble plus fortement lié aux rythmes de la fatigue et du sommeil. D’autres explications possibles – la suppression de l’expression des rythmes circadiens et/ou le déverrouillage de celle des rythmes ultradiens de la performance cognitive en situation stressante, compétitive ou revêtant un enjeu vital – sont également envisagées. Dans son ensemble, notre étude permet de considérer de nouvelles pistes en matière de chronoprévention des risques chez les SP, basées sur l’étude des rythmes biologiques, psychologiques et sociaux. Cette recherche a bénéficié du soutien du SDIS 71, du Fond National de Prévention de la CNRACL et a été approuvée par le Comité de Protection des Personnes Est 1 / The aim of this study was to assess the impact of biological and psychological rhythms on the firefighters (FF) activity. The 1st part of our study was performed on FF’s interventions databases. 24-h pattern of lag time (LT), duration in min between a call and departure of service vehicle for out-of-hospital cardiac arrest (OHCA), and 24 pattern of relative risk of work-related injuries (WRIRR) of FF (which takes into account the number of at-risk FF/unit time), were assessed on a 4y span.. This analysis revealed a 24-h variation in LTOHCA and in WRIRR, with both a nocturnal peak. The stability of the LTOHCA rhythm between years and seasons and its weak relationship with the OHCA 24-h pattern favored the hypothesis of an endogenous component or origin. Moreover, for the same FF population, LTOHCA and WRIRR patterns were positively correlated : the hypothesis of a common mechanism linking performance and accidents seemed to be validated. The 2cd part assessed the differences in τ, of 16 coexisting rhythms of 30 healthy FF of mostly comparable average age, body mass index, career duration, chronotype—morningness/eveningness. Data of the self-assessed 16 circadian rhythms were gathered continuously throughout two 8-d spans, in winter and in summer. The desynchronization ratio (DR: nb of variables with τ≠24.0h/nb of variables x100) served to ascertain coexistence of rather strong and weak circadian oscillators, fro which the gradient reflects interindividual differences in FF’s DR. These différences are consistent with the hypothesis of an inherited origin of a differential propensity to circadian desynchronization. It pointed also the fact that, although a nocturnal trough of WRIRR and LTOHCA was confirmed, the rhythms of performance were inexistants for most of the FF of our study, refuting the classical hypothesis of a standalone link between variations of performance and accidents. These results also put into perspective new possible explanations of black time. We propose the 24 h pattern of WRIRR, particularly of FFs and other highly skilled self-selected cohorts, is more strongly linked to circadian rhythms of fatigue and sleepiness than cognitive performance. Other possible explanations –suppressed expression of circadian rhythms and/or unmasking of ultradian periodicities in cognitive performance in specific circumstances, e.g., highly stressful work, competitive, or life-threatening settings, are also discussed. Furthermore, the whole study allows to consider new paths in chronoprevention of risks in the FF profession, based upon the study of biological, psychological and social rhythms. This study was supported by the Fire Departement of Saône et Loire (France), the French National Fund for the Prevention of Occupational Accidents and Diseases of the French National Pension Fund for Administrative Division Officials, and was approoved by a regular ethics comittee

This study was concerned with establishing the extent to which various components of the environment were exposed to the three toxic minerals, arsenic, mercury and lead. The concentration of these three elements were determined in groundwater and surface water, soil, plants, animals such as goats, and humans in potentially contaminated areas in the Limpopo Province of South Africa. The focus of the study was to assess the possible exposure to infants through ingestion to arsenic, mercury and lead. Comparison of the mineral content of water at the study sites with international and national drinking water standards, indicated water from Rooiberg, Leeupoort and Gravelotte are not fit for human consumption due to high arsenic and lead concentrations. Water at Gravelotte also has unacceptably high levels of mercury. The soil, plants, goat’s milk and mother’s milk at Rooiberg have higher levels of arsenic and lead than have been recorded for many other countries. Mother’s milk and goat’s milk are the main sources of arsenic, lead and mercury contamination at Rooiberg. It is therefore newborns and toddlers who are most at risk from exposure to arsenic and lead. This is a cause for environmental and health concerns, but as this research is only a base-line study, it is imperative that more comprehensive surveys of potentially toxic mineral contamination be conducted in the province. / Environmental Sciences / (M.Sc.

I prepared my thesis on Health Support at Workplaces under Particular Conditions of a Textile Factory. The main objective was to determine the company management?s activities in the field of health support. The second objective was to map the information provided to the staff on health support at the workplace, and the third objective was to propose the concept of a specific preventive programme. When preparing the concept of the preventive programme for the textile company I co-operated with the company management and with the company doctor. The reference group was represented by women employed in a textile plant in South Bohemia who worked in different workshops producing car seat covers, housing and children?s clothing. The work described in this thesis was carried out as quantitative research. For data collection I used anonymous questionnaires and the results of this research were plotted on graphs. The thesis is divided into a theoretical part and an empirical part. The theoretical part mainly deals with health support at the workplace, with an analysis of health risks at work including the impact of physical factors. At the beginning of the empirical part I set the goals and set out three hypotheses. Having analysed the collected data I found that H1, H2 and H3 were confirmed. The empirical section includes a description of the research technique which shows that more than 50 per cent of employees of the textile factory are overweight, then that there is a greater occurrence of health problems in the departments of sewing and embroidery machines and many women also had no idea of the meaning of health support at the workplace. According to the results it is possible to say that the textile company does not organize any physical activities or rehabilitative exercises for their employees. Based on the information I would recommend organizing sports courses, providing healthy canteen meals, reducing stress at the workplace and introducing dust extractors in order to reduce dust at the workplace. This thesis may bring the company better working comfort and help to improve the employees? health. The proposed preventive programme can also be a manual for employers in the textile plant in the field of health support at the workplace.

Impacts of global climate changes in the form of repeated natural disasters are becoming a part of the day-to-day life of the present-day society. The issue of preparedness for extraordinary and crisis situations is becoming more and more topical. The Czech Republic is no exception; it regularly faces heavy rains, floods or snow. The key prerequisite for successful management of these emergencies is an effective prevention and preparedness in the form of crisis plans or crisis preparedness plans. The objective of my thesis is to find out whether Emergency Medical Service of Zlín Region is sufficiently prepared for the occurrence of emergencies and to propose solutions if shortcomings are identified. The Emergency Medical Service of Zlín Region constitutes a basic component part of the Integrated Rescue System of Zlín Region. As a provider of emergency medical services, it is included in the Crisis Plan of Zlín Region. Capacity for action and the activities of the Emergency Medical Service of Zlín Region have to be ensured not only in day-to-day operation, but also if an emergency occurs and continues. The theoretical part of my thesis provides a general overview of emergency and crisis planning, competencies of administrative authorities with respect to emergency medical services in case of an emergency situation announcement, traumatology plan and pandemic plan. This chapter includes also characterization of the legal entity of Emergency Medical Service of Zlín Region and description of special antropogenic and natural threats. The theoretical part is followed by qualitative research, which involves in particular a detailed study of available professional resources in printed and electronic form, especially crisis and emergency planning documents of Zlín Region and internal documents of Emergency Medical Service of Zlín Region. The practical part of the thesis contains an analysis of external and internal threats at respective ambulance stations of Emergency Medical Service of Zlín Region. The external risks analysis is based on the Crisis Plan of Zlín Region and Emergency Plan of Zlín Region, while the internal risks analysis is based on an expert estimate of potential risks at respective ambulance stations of EMS ZR. I assigned the potential impact on the activity of EMS ZK to each identified risk in the risk analysis. The outputs from the analysis became the main source for the preparation of the crisis preparedness plan. The analysis of external risks confirmed that agility and EMS ZK activities may disrupt in particular the following threats: natural flood (ambulance station in Zlín Peroutkovo nábřeží, Uherské Hradiště, Vsetín), special flood (ambulance station in Zlín - Peroutkovo nábřeží, Karolinka, Vsetín), risks arising from climatic conditions (especially heavy snow in Wallachia), disruption of pharmaceuticals and medical supplies (secondary consequence of the crisis) and electricity cuts (especially ambulance stations that do not dispose of emergency power unit). The thesis result is a proposal of Crisis Preparedness Plan of Medical Emergency Service of Zlín Region. A legal entity or an individual who secures the performance of measures resulting from the regional crisis plan is responsible for the preparation of the crisis preparedness plan. The particulars and manner of preparation of the crisis preparedness plan are described in detail in the Government Decree No. 462/2000 Coll., which implements the provisions of Sec. 27(8) and Sec. 28(5) of Act No. 240/2000 Coll., on Emergency Management and Amendment to Some Acts. When drafting the plan I proceeded according to valid legislation. This plan is an internal document of the legal entity to solve the challenges of security in crisis situations.

This thesis and the feasibility study, which is attached to the thesis, solves the complex issue of the technology rehabilitation in the unit of the voluntary fire brigade of the village of Solenice using a subsidy program for the purchase of a large-capacity tank syringe with use for the cadastre of the municipality of Solenice. The aim of this work is to prepare a risk analysis for the cadastral territory of the municipality of Solenice in connection with the document entitled "Feasibility study", which is an indispensable part of the documents for submitting the application for the data title for restoration of obsolete fire fighting equipment in the municipality. This document focuses on the description of the cadastre of the village and its unit, its layout and its significance from the point of view of the IRS, which is based on the plan coverage of the fire protection units. This paper deals with the necessary documents focusing on the application and the successful realization of the project in order to restore the fire technology in our village and thus to improve the unit's operational capability using the newly acquired technique. This document will save the municipality to make a Special Assessment and will allow the savings to invest in other projects according to the current grant calls and needs of the municipality.

[pt] O planejamento e controle de portfolios de projeto é uma tarefa desafiadora. Eles estão sujeitos a múltiplos riscos, restrições de recursos, relações de precedências e penalidades por atrasos de projetos. É fundamental desenvolver estratégias efetivas de alocação dos recursos disponíveis de forma a garantir que estes projetos sejam concluídos dentro dos limites de tempo e custo. Um fator crucial que deve ser levado em consideração ao tomar estas decisões é o gerenciamento das incertezas associadas a execução dos projetos. Neste contexto, este trabalho propõe uma metodologia baseada em otimização robusta para planejamento e controle de portfolios de projeto sob incerteza. Este método combina modelos e algoritmos desenvolvidos para diferentes problemas de alocação de recursos para os quais foi aplicada a mesma abordagem de otimização robusta. Nela, a incerteza é modelada como um adversário capaz de materializar a combinação de riscos de pior caso que maximiza o impacto no(s) projeto(s) para qualquer plano de alocação de recursos. Nos problemas estudados o tomador de decisão tem então que determinar a alocação ótima de recursos que minimiza um objetivo particular assumindo que a combinação de riscos de pior caso irá se materializar. A abordagem também provê um mecanismo para controle do grau de conservadorismo das soluções robustas. Para cada problema modelado, uma estratégia de solução é desenvolvida através de um esquema de reformulação que parte de uma formulação Min-Max compacta e termina em um algoritmo de geração de cortes. Diversos experimentos computacionais foram executados, provendo importantes conclusões que direcionaram o desenvolvimento da metodologia de controle e planejamento de portfolios. A importância de se desenvolver planos de alocação de recursos de forma integrada no contexto de tomada de decisão em portfolios de projetos e a falta de efetividade do método tradicional de análise de caminhos críticos no contexto de cenários de pior caso para as durações das atividades, são importantes exemplos das conclusões obtidas pelos experimentos. A aplicação da metodologia foi demonstrada em um caso de estudo que contempla um portfolio para construção de duas refinarias. O referido exemplo demonstrou o potencial do uso prático dos métodos propostos neste trabalho. / [en] Planning and controlling complex project portfolios is a challenging task. These portfolios are subject to a number of potential risk sources coupled with resource constraints, intricate precedence relationships, and penalties for project delays. For this reason, it is fundamental that optimal strategies for the allocation of the available resources are constantly adopted by the decision makers to ensure that their projects are completed within limits of time and cost. Moreover, the uncertainty that affects these projects has to be taken into account for effective resource allocation decisions. Within this context, this work proposes a robust optimization-based methodology for planning and controlling project portfolios under uncertainty. The method combines models and algorithms for multiple resource allocation problems under the same robust optimization framework. In this approach, the uncertainty environment is modeled as an adversary that selects the worst-case combination of risks for any decision maker s actions. Subsequently, the main goal of the decision maker is to determine optimal resource allocation plans for minimizing a particular objective subject to the assumption that the adversary s worst-combination of risks will materialize. The approach also provides a way to control the degree of conservatism of the solutions. For each studied problem, a solution strategy is developed through a reformulation scheme from a compact min-max formulation to a cut-generation algorithm. Several computational experiments are conducted, providing key insights that drive the design of the referred portfolio planning and control methodology. The ineffectiveness of traditional critical path analysis under worst-case realizations of uncertain activities durations and the importance of taking integrated resource allocation decisions in the context of project portfolios, are examples of the key findings of the experiments. The application of the methodology is demonstrated in a case study of a portfolio aimed at the construction of two refineries. This example presents the capabilities of the developed techniques in a practical context.

Being even more worrying when contaminate groundwater for public supply, as the case of Natal City. For this reason, the Public Ministry/RN, in partnership with UFRN, developed the project environmental suitability of Gas stations in Natal, of which 36% showed evidence of contamination. This paper describes the four stages of the management of contaminated areas: preliminary assessment of environmental liabilities, detailed confirmatory investigation of the contamination, risk analysis to human health (RBCA), as well as the remediation plan of degraded areas. Therefore it is presented a case study. For the area investigated has been proposed a mathematical method to estimate the volume of LNAPL by a free CAD software (ScketchUp) and compare it with the partition method for grid area. Were also performed 3D graphics designs of feathers contamination. Research results showed that passive benzene contamination in groundwater was 2791.77 ?g/L, when the maximum allowed by CONAMA Resolution 420 is 5 ?g/L which is the potability standards. The individual and cumulative risks were calculated from 4.4 x10-3, both above the limits of 1.0 x10-5 or by RBCA 1.0 x10-6 by the Public Ministry/RN. Corrective action points that remediation of dissolved phase benzene is expected to reach a concentration of 25 ?g/L, based on carcinogenic risk for ingestion of groundwater by residents residential, diverging legislation. According to the proposed model, the volume of LNAPL using the ScketchUp was 17.59 m3, while by the grid partitioning method was 14.02 m3. Because of the low recovery, the expected removal of LNAPL is 11 years, if the multiphase extraction system installed in the enterprise is not optimized / Atividades que possuem sistema de armazenamento subterr?neo de combust?veis s?o consideradas potencialmente poluidoras pela Resolu??o CONAMA 273/2000, devido ? possibilidade de vazamento, derramamento e transbordamento de combust?veis para o solo. Sendo ainda mais preocupante quando contaminam ?guas subterr?neas destinadas ao abastecimento p?blico, como o caso de Natal. Por este motivo, o Minist?rio P?blico/RN, em parceria com a UFRN, desenvolveu o projeto de adequa??o ambiental dos postos revendedores de combust?veis em Natal, dos quais 36% apresentaram ind?cios de contamina??o. Este trabalho descreve as quatro etapas do gerenciamento de ?reas contaminadas: avalia??o preliminar do passivo ambiental, investiga??o confirmat?ria detalhada da contamina??o, an?lise de risco a sa?de humana (RBCA), bem como o plano de remedia??o das ?reas degradadas. E apresenta um estudo de caso. Para a ?rea investigada ? proposto um m?todo matem?tico para estimar o volume de fase livre auxiliado por um software CAD livre (ScketchUp), este foi comparado com o m?todo de parti??o da ?rea por grid. Tamb?m s?o realizados os designs gr?ficos 3D das plumas de contamina??o. Os resultados da investiga??o de passivo mostraram que a contamina??o por benzeno na ?gua subterr?nea foi 2791,77 ?g/L, quando o m?ximo permitido pela Resolu??o CONAMA 420/2009 ? de 5 ?g/L que ? o padr?o de potabilidade.
