Lopez, Sylviane. "Transformation de l'activité d'apprenants de l'enseignement professionnel en situation de presque accident : une approche énactive". Electronic Thesis or Diss., Université de Toulouse (2023-....), 2024. http://www.theses.fr/2024TLSEJ014.
Pełny tekst źródłaThe thesis entitled « Transformation of vocational learners’ activities in near-accident situations An enactive approach » focuses on the imperative of preventing accidents among learners in agricultural education during their professional training period in companies. The goal is to explore learner activity in risky professional situations, with particular attention to the population of young workers. It aims to decipher their behaviors and attitudes in potentially dangerous situations and identify variables influencing their decision-making processes, thereby enhancing understanding of issues related to occupational health and safety (OHS). Themethodology adopted relies on the intersection of Vermersch’s psychophenomenology Vermersch, 2012; Depraz et al., 2011) and the explicitation interview, combined with the Empirical Research Program of Course of Action within the enactive paradigm proposed by Theureau (2004a, 2015). This theoretical combination enables the analysis of learners’ work ituations in near-accident scenarios, which refer to situations that could have resulted in an accident. This qualitative and heuristic study comprises 11 case studies : five interviews with apprentices in Apprenticeship Training Centers, three with students in Rural Family Houses, and three with students in initial training in agricultural high schools. The aim is to describe, through xplicitation interviews, the lived experience during near-accident situations, without making prior assumptions about the learning process, and to identify factors that have facilitated or indered the learners’ protection. In this perspective, the primary objective is to capture the subjective experience of learners in order to understand how their activity transforms during this specific moment, referred to as the « moment of reversal » (t = r ). The analysis of « courses of experience » allows for understanding the factors that led to the incident, shedding light on the transformations of the activity. The results of this research reveal the intentional ambivalence of learners, manifested by their dual intention to meet social and personal expectations while taking risks to demonstrate their competence. Various fundamental concerns influence the transformation of young individuals’ activity during their decision-making processes, including contrasting emotions ranging from confidence to incomprehension, as well as feelings of pride and anger towards oneself, disappointment, and fear. Furthermore, a strong determination to fully engage in tasks, to succeed, to avoid delays and meet deadlines, a particular attention to details and landmarks, such as lunchtime, and anticipation of tasksto be accomplished, quick and effective reactions to unexpected or dangerous situations (sometimes surprising), and a pronounced self-critique and sense of guilt in case of failure. These results suggest potential implications for accident prevention and improvement in the pproach to health and safety at work among learners. The thesis emphasizes the necessity for actors involved in learner training during their work placements to consider the levels of leaning and contextual dimensions relevant to the learner

Pełny tekst źródłaBlunt aortic rupture (BAR) is the second leading cause of death following blunt trauma in motor vehicle crash accidents (MVCAs). Aortic distraction was postulated to be a primary BAR mechanism, but intra-aortic pressure effect on BAR is controversial. Previous finite element (FE) simulations did not simultaneously study the BAR mechanisms of the two contribution sources. Therefore, the BAR mechanisms remain to be ascertained under the effects of physiological intra-aortic pressure and intra-thoracic interactions during MVCAs.Our objective is to investigate BAR mechanisms in MVCAs with a focus on intra-aortic pressure. The work is organized: 1) to quantify aortic responses under cardiac function, 2) to identify the necessity of considering intra-aortic pressure, 3) to develop a FE model including both injury contribution sources and 4) to investigate BAR mechanism during MVCA with the new model. The aortic responses under cardiac loadings should be considered for BAR. Intra-aortic pressure could induce a significant BAR risk. BAR in MVCA resulted from a combined mechanism with aortic stretch and intra-aortic pressure as the primary and secondary cause

Pełny tekst źródłaThe study focuses on the fluctuation of levels of tolerance regarding road insecurity within the period of fifty years. Firstly, the study looks at the way road accident peddles and produces social representations. Various procedures then are explored to underline the drama : spectacular pictures, expressions of the tragic, shocking headlines that come to attract the reader's attention by provoking amazement and deep emotions. Secondly, the study shows how in fifty years the French society has shifted from the fatalistic view that the accident was the doomed fate of traffic to the certainty that problems of road safety can be overcome by preventive and punitive actions. Finally, road security appears as an "absolute social phenomenon". Any accident brutally unveils living conditions as well as social and professional inequalities between road users. It is also an indicator of social values. Furthermore, road security has become an instrument of political pressure for a few years now
Laboureur, Delphine. "Experimental characterization and mondeling of hazards, BLEVE and BOILOVER". Doctoral thesis, Universite Libre de Bruxelles, 2012. http://hdl.handle.net/2013/ULB-DIPOT:oai:dipot.ulb.ac.be:2013/209603.
Pełny tekst źródłaThe objective of this thesis is to study the apparition criteria and the consequences of an accident involving a container of pressure liquefied gas (BLEVE phenomenon) or liquid fuels (Boilover phenomenon). After a bibliographic research on the two phenomena, an experimental study in laboratory scale is conducted and from the results, the phenomena and their hazards are modeled. Small scale experiments are performed in the BABELs facility (Bleve And Boilover ExperimentaL setup) that consists of a cylindrical chamber of 2m diameter and 3m high, with round shape flanges, made out of steel with a rated pressure of 0.5 MPa. It has 3 series of 7 optical accesses, an entrance door, and an optional air venting system.
A Boilover is a violent ejection of fuel due to the vaporization of a water sublayer, resulting in an enormous fire enlargement and formation of fireball and ground fire. Small scale experiments with cylindrical reservoirs of 0.08 to 0.3m diameter in glass or metal, filled with a mixture of diesel and oil have been performed. Instrumentation of the measurements consists of thermocouples rake, Medtherm radiometers, load cell and CCD or high-speed camera with a fisheye. During the quasi-steady combustion prior the Boilover, the typical variables describing a pool fire like burning rate, flame size, puffing frequency and radiation can be predicted with semi-empirical correlations available in the literature. At Boilover onset, high speed visualizations in glass reservoir show that the growth of one big bubble leads to a boiling front that propagates radially all along the fuel-water interface, ejecting the upper fuel layer and leading to the increase of flame size. LS-PIV technique applied to high-speed camera images shows that the flame enlargement is directly linked to the velocity of the flame.
A BLEVE (or Boiling Liquid Expanding Vapour Explosion) is an explosion resulting from the catastrophic failure of a vessel containing a liquid at a temperature significantly above its boiling point at normal atmospheric pressure. Small scale experiments are performed with cylinders of 42g of propane, laid horizontally and heated from below by an electrical resistor. A groove of the reservoirs on the upper part allows better reproducibility of the rupture. High speed visualization and shadowgraphy are helping in visualizing the rupture and the content release. Thermocouples and PCB are also used to measure respectively the temperature and the blast wave overpressure. These experiments show that the fluid behavior during rupture differs with the size of the weakened part and therefore with the rupture pressure. The internal pressure measurement showed that the rupture pressure and temperature are supercritical, leading to the definition of a new type of BLEVE since there is no distinction between liquid and vapor phases prior rupture.

Nop, Raksmy. "Experimental investigation and modeling of the transient flow boiling crisis of water at moderate pressure and high subcooling". Thesis, université Paris-Saclay, 2020. http://www.theses.fr/2020UPAST046.
Pełny tekst źródłaIn case of a reactivity insertion accident in an experimental nuclear reactor, heat generation in the core can grow exponentially in time, with a power escalation period ranging from a few to a few hundreds of milliseconds. Due to neutronic and thermohydraulic effects, boiling crisis may arise, possibly leading to an explosive reaction. If the boiling Crisis has been widely investigated in steady-state conditions, this has not been the case for transient heat inputs. The aim of the present work is to understand and to predict the transient flow boiling crisis in the conditions of moderate pressure and high subcooling. To this end, an experimental campaign has been realized making use of space and time highly resolved videos and IR thermography covering a wide range of experimental parameters. The analysis of the massive amount of data produced by these experiments gives a better insight on the dependency of the transient Critical Heat Flux to the different parameters of interest (power escalation period, flow velocity, subcooling, pressure, channel width, heating length). Moreover, their fine analysis enables to highlight the underlying mechanisms. For conditions of forced flow and high subcooling, the bubbles generated at the wall present a pulsating behavior. This specific process leads to an efficient heat transfer from the wall to the neighboring fluid. Boiling crisis is stated to occur when a thin layer of liquid contacting the wall reaches the saturation temperature. Starting from these observations, a model is developed which brings to light two non-dimensional parameters useful to describe the transient nature of the process and the dominant cooling processes. With the knowledge of the steady-state CHF, the model permits to conservatively estimate the value of the Critical Heat Flux for any power escalation period and subcooling. This model is now ready for implementation into simulation codes to investigate nuclear accidental transients

"Syndrome d'apnées du sommeil et cerveau : une relation bidirectionnelle Continuous positive airway pressure improves gait control in severe obstructive sleep apnoea: A prospective study Hypoxic conditioning and the central nervous system: A new therapeutic opportunity for brain and spinal cord injuries?" Thesis, Université Grenoble Alpes, 2020. https://thares.univ-grenoble-alpes.fr/2020GRALS025.pdf.
Pełny tekst źródłaThe human brain is a perfect example of our dependence on oxygen. Brain physiological constraints render it vulnerable to hypoxia, such as encountered in environmental conditions (high altitude exposure) or pathological hypoxemic conditions. Among those pathological conditions, and due to its high prevalence in general population and the various levels of hypoxia resulting of the different degrees of severity of the pathology, obstructive sleep apnoea syndrome (OSAS) is a pathophysiological model of choice to investigate the detrimental effects of hypoxia on the brain. The cyclical, repeated episodes of apnoea and hypopnea during sleep that characterize OSAS result in intermittent hypoxia, sleep fragmentation and fluctuations in intrathoracic pressure, which are stressors that triggers mechanisms contributing to the initiation and progression of life-threatening cardiometabolic diseases, as well as several brain repercussions, such as cognitive impairment and stroke. This Thesis work explores the bidirectional relationship between sleep apnoea syndromes (SAS) and the brain. The first axis is focused on the neurocognitive consequences of OSAS through the lens of gait control. The neurocognitive signature of OSAS has been thoroughly investigated but recently, gait impairments have been highlighted in severe OSAS, with dose-response relationship between OSAS severity and the magnitude of gait impairments. As gait control relies at least partly on frontal lobe functions, it has been suggested that gait could represent a marker of OSAS brain repercussions. We investigated the effects of continuous positive airway pressure (CPAP) treatment on gait control, with contrasting results. In a first prospective controlled study, eight weeks of CPAP improved gait control in severe OSAS patients (Baillieul et al., 2018, Plos One). In order to validate those results and investigate the neurophysiological correlates of the link between gait control and OSAS, we conducted a randomized controlled trial which investigated the impact of an 8-week CPAP treatment compared to sham-CPAP on gait control in severe OSAS patients (Baillieul et al., 2020, Submitted). Contrary to our hypothesis, we found no improvement in gait control in the CPAP group and this result is substantiated by the absence of impact of CPAP on the determinants of gait control, further illustrating the complexity of the OSAS-neurocognitive relationship. The second axis is focused on the cerebrovascular repercussions of SAS. SAS and stroke are both severe intertwined conditions, SAS being both cause and potentially consequence of stroke. The present work is focused on the identification of phenotypic traits of SAS in post-stroke patients, to improve diagnosis of SAS following stroke (Baillieul et al., in preparation). Screening stroke patients for SAS is crucial due to the high risk of morbimortality and functional consequences associated to SAS following stroke but cannot be achieved without a more accurate identification of patients at risk to develop SAS following stroke. The third axis has been conceived as a perspective that will serve the development of the second axis. In this last axis, the potential of brain imagery and in particular magnetic resonance imagery to develop markers of stroke recovery as well as investigate the pathophysiological mechanisms underlying stroke-related deficiencies are presented, with a specific focus on gait and walking activity. The neural correlates of walking activity following stroke are highlighted, using a voxel-based lesion-symptom mapping approach (Baillieul et al., 2019, Hum. Mov. Sci.). Imagery markers of walking recovery following stroke using diffusion tensor imaging are also presented (Soulard et al. 2019, Neurology). This work on brain imagery markers of stroke recovery will further serve the development of investigations focused on the neural correlates of SAS following stroke

Nicolaï, Alice. "Interpretable representations of human biosignals for individual longitudinal follow-up : application to postural control follow-up in medical consultation". Electronic Thesis or Diss., Université Paris Cité, 2021. http://www.theses.fr/2021UNIP5224.
Pełny tekst źródłaIndividual longitudinal follow-up, which aims at following the evolution of an individual state in time, is at the heart of numerous public health issues, particularly in the field of medical prevention. The increasing availability of non-invasive sensors that record various biosignals (e.g., blood glucose, heart rate, eye movements), has encouraged the quantification of human physiology, sensorimotricity, or behavior with the purpose of deriving markers for individual follow-up. This objective raises however several challenges related to signal modelling. Indeed, this particular type of data is complex to interpret, and, a fortiori, to compare across time. This thesis studies the issue of extracting interpretable representations from biosignals through the problematic of balance control follow-up in medical consultation, which has crucial implications for the prevention of falls and frailty in older adults. We focus in particular on the use of force platforms, which are commonly used to record posturography measures, and can be easily deployed in the clinical setting thanks to the development of low cost platforms such as the Wii Balance Board. For this particular application, we investigate the pros and cons of using feature extraction methods or alternatively searching for a generative model of the trajectories. Our contributions include first the review and study of a wide range of state-of-the-art variables that are used to assess fall risk in older adults, derived from the center of pressure (CoP) trajectory. This signal is commonly analyzed in the clinical literature to infer information about balance control. Secondly, we develop a new generative model, ``Total Recall'', based on a previous stochastic model of the CoP, which has shown to reproduce several characteristics of the trajectories but does not integrate the dynamic between the CoP and the center of mass (CoM) -- a dynamic which is considered to be central in postural control. We also review and compare the main methods of estimation of the CoM in quiet standing and conclude that it is possible to obtain an accurate estimation using the Wii Balance Board. The results show the potential relevance of the Total Recall model for the longitudinal follow-up of postural control in a clinical setting. Overall, we highlight the benefit of using generative models, while pointing out the complementarity of features-based and generative-based approachs. Furthermore, this thesis is interested in introducing representations learned on labeled data and tailored for a particular objective of follow-up. We propose new classification algorithms that take advantage of a priori knowledge to improve performances while maintaining complete interpretability. Our approach relies on bagging-based algorithms that are intrinsically interpretable, and a model-space regularization based on medical heuristics. The method is applied to the quantification of fall risk and frailty. This dissertation argues for the importance of researching interpretable methods, designed for specific applications, and incorporating a-priori based on expert knowledge. This approach shows positive results for the integration of the selected biosignals and statistical learning methods in the longitudinal follow-up of postural control. The results encourage the continuation of this work, the further development of the methods, especially in the context of other types of follow-up such as continuous monitoring, and the extension to the study of new biosignals

Road traffic accident handling is highly professional and complex work, the supervision of the state in 91 year and 102 year for the road traffic accident related business to correct the case. The current police agencies have been responsible for traffic accident handling units and personnel, however, in the case of traffic accidents and the number of casualties in recent years continue to surge in the circumstances, responsible for road traffic accident handling police workload, work pressure and job burnout is becoming increasingly important attention. The main purpose of this study is: 1、To explore the different basic characteristics of the traffic accident handling police officers, the work of the feelings of the situation. 2、Explore the relevant circumstances of the traffic pressure and the coping strategies of police officers responsible for traffic accidents. 3、To study the basic characteristics of the traffic accident handling police officers, the impact of work pressure on the response strategy and forecast. 4、To construct a forecasting model that affects the traffic pressure handling of police officers, and to propose specific and constructive immediate and feasible long-term recommendations for the management of the police authorities. There are few studies on the work pressure and response strategy of the police officers involved in the road traffic accident handling. At present, this paper summarizes the work pressure and response strategy of the police officers responsible for traffic accident handling, Taichung Government Police Bureau for traffic accident handling police officers, the implementation of the questionnaire, after the pre-test subjects 27 copies, a total of 340 questionnaires issued, after the withdrawal of invalid questionnaires, fill incomplete and dishonesty respondents, completely there were 294 effective questionnaires, the effective recovery rate was 86.47%. And then the data collected by the statistical program SPSS data processing and analysis, and the number of times and percentage, one-way anova, t-test, pearson product-moment correlation, multi-regression analysis and other methods to analyze the results are as follows: 1、Different "marital status" and "police from the police" dedicated traffic accident handling police officers feel the pressure on the work of a significant level. 2、Different "average monthly handling of the number of accidents" dedicated traffic accident handling police officers on the application of the strategy to achieve significant standards. 3、The greater the pressure on police officers to deal with road traffic accidents, the greater the pressure to deal with the problem of "direct problem solving", "logical analysis and handling" and "emotional depression". Will use the "emotional adjustment to adapt" and "seek support from all parties" and other strategies to respond. 4、The "basic characteristics of the individual" have a significant impact on the overall "work stress" scale, which has a correlation between "personal basic characteristics" and "work stress", that is, the ability to predict between "personal basic characteristics" and "work stress".Which is better equipped with different "police education", "handling of A1 accident experience" and "service area" for "work pressure". 5、The "Work Stress" scale significantly affects the overall "response strategy" scale to verify that there is a correlation between "work stress" and "response strategy", that is, between "work stress" and "response strategy".The best use of the "work factor" and "organizational factors" for the "response strategy". Finally, according to the above analysis results, put forward relevant research proposals for working pressure and response strategies and follow-up research recommendations.

As automotive technology has been developing rapidly, customers have more and more demands on vehicles nowadays. Casting huge funds in research and development, many automobile companies pay a lot of attention on the vehicle safety control system. In order to raise driving speed, lower fuel consumption, diminish exhaust and enhance handling, vehicle safety and handling performance are highly demanded. Driving speed is raised because vehicle performance and the stability of suspension system are enhanced. It is pretty easy to speed up to one hundred kilometer per hour by stepping on the accelerator slightly. Therefore, in addition to improve handling performance, a relatively important unit for safety control is the tire, that is in contact with the ground. It is crucial to maintain tires in good condition all the time. In view to high accident rates for cars in Taiwan, inadequate maintenance is usually an important factor. Accident rates those result from tires are especially high because drivers disregard the maintenance knowledge, or do not have enough defensive tools for tire pressure detection, so that, pressure and temperature changes inside tires are not detected in time. According to the National Freeway Bureau’s statistics, 70% of the major accidents arise from tire puncture. Among those major accidents recently, 30% of those are classified as tire problems; and 75% of the problems are owing to tire leaking or insufficient tire pressure. This thesis studies an important issue about traffic safety in Taiwan presently, that is, the acknowledgement of using tires safely and tire pressure detectors. Whether the government propagates and carries out policies for tire puncture safety sufficiently and whether safety equipment installation in cars promotes effectively are indispensable and extremely important for life safety of all road users, which include drivers and pedestrians. In order to understand integrative requirements of defensive tire pressure detectors for market end-users, this study is performed by means of questionnaires. This research offers references to car users for preventing from accidents, which may result from neglected maintenance, or delay of replacing or installing defensive tire detectors due to price consideration. Consumers can realize and weigh between value and price. By collecting 47 SPSS questionnaires, which are focused on consumers who are considering and possibly going to replace tires and tire pressure detectors, this research confirms matters those consumers think over before transaction. Besides, 121 questionnaires of the AHP predicting mode are issued to drivers who have visited the service centers. Moreover, 142 questionnaires are issued and studied through the web. All data, being analyzed and verified, are offered to the service centers belongs for elaborating sale techniques, which can be used to help customers to decide the replacement or installation and to reduce accidents.
