Walsh, Paul David. "Accident or design : to what extent do teachers plan and own their professional learning?" Thesis, University of Roehampton, 2014. https://pure.roehampton.ac.uk/portal/en/studentthesis/accident-or-design(2608a0c3-98d3-4197-9dae-0bd34c1fa37c).html.
Full textAbstract:
Professional learning, a key aspect of teacher professionalism, receives considerable interest from the academic and policy making communities; however it is an area with limited empirical evidence specifically relating to teachers working in special schools. This research examines the extent to which eight teachers working in two special schools have ownership and are able to plan their professional learning within the context of whole school Continuing Professional Development (CPD) processes and activities. It explores whether transformative models of CPD (Kennedy, 2005) offer teachers more support in making choices about professional learning, examining the issues from the perspective of both the teacher and the school. A distinction is made between professional learning, professional development and CPD. Professional development and CPD refer to the planning, organisation and delivery of professional development activities within schools. Professional learning is the process whereby teachers move towards a greater level of expertise as an outcome of formal and informal professional development. An interpretive methodology was used to analyse qualitative data gathered from semi structured interviews and school documentation, to build two case studies. Computer assisted qualitative data analysis software was used within the interpretive approach to analyse the data; the intention was to look for patterns and themes in the case studies in order to examine the planning and ownership of professional learning. The emerging picture of how effectively teachers were able to plan their learning was a complex one, with teachers expressing variable degrees of ownership and planning. Special school training needs, based on a medical model of identification and intervention, impacted upon the degree to which the teachers interviewed felt that their planning of professional learning was effective. The interpretation of the findings concluded that the effectiveness of the planning of professional learning was curtailed by a lack of personalisation in the organisation of whole school CPD and a lack of coherence between whole school CPD planning and the teachers’ professional learning focus. Evidence revealed that institutional development needs and special school improvement issues often took precedence over teachers’ professional learning needs.

Alahdal, Alhosain Abdullah. "Family support plan for Middle Eastern countries following aircraft accidents." Thesis, Cranfield University, 2010. http://dspace.lib.cranfield.ac.uk/handle/1826/6850.
Full textAbstract:
Recent years have seen increasing acknowledgment that aircraft accidents
affect not only those who are killed or injured, but also the families and friends
of victims. Survivors, victims and their families require sensitive treatment in
order to help them cope with what has occurred. Following high profile
accidents including USAir 427 and TWA 800, the United State of America
started a new program which they call it Family Assistance after Air Disaster.
After that a several documents providing guidance for dealing with victims and
their families were published in Australia, the UK and the EU.
However, in the Middle East, there is no region-specific family assistance
guidance for dealing with aircraft accidents. As such, operators tend to use
plans which have been designed from a western perspective. This means that
the impact of culture, ethical sensitivities and religion have not been addressed
fully. This thesis explores the differences in dealing with the families of victims
after an accident in the Middle East focusing on the Muslim population.
Interviews were conducted with experts from airlines, family assistance
providers, religious leaders and victim support groups. These were
supplemented by a survey of passengers and family members in USA, Malaysia
and Saudi Arabia to compare and contrast the expectations and needs of those
who may be affected by an aircraft accident. Over 300 responses were received
and the data were validated through further expert interviews. The results
supported the findings of the literature review and matched with the bad
experiences documented within case study accidents such as the mid-air
collision involving Saudi Arabian Airlines flight 763. The study found that the
three factors are inextricably linked, with religion being a strong factor in
determining individual’s response to their loss; how they relate to others and the
type of support they should be given. Suggestions are made regarding the
design of a Family Assistance Centre, staff training, words that should / should
not be used; and to explain how people may react.

Full textAbstract:
The aim of this study is to compare the cause of the, to date, three onlycommercial nuclear power plant accidents. These are very complex incidents,which have dire impact on society and the environment and therefore benefitfrom further investigation, if there lays a possibility of identifying factors thatcould prevent further accidents in the future. In order to investigate this theactions and decisions that lead up to each nuclear meltdown was identified andcompared.The investigation was based on a qualitative study on three cases of nuclearmeltdown accidents. They are based on text analysis of official reports anddocumentaries on the subject. The theoretical background for this study wasKajtazi’s (2011) work on Information Inadequacy. The study was limited to theevents leading up to the accidents and do not include activities afterwards.The study shows that each case had different underlying reasons. It alsoshows that we seem to have learned something from our previous mistakes, andacted on them accordingly. From the Fukushima Daiichi accident we canrecommend that organizations in charge should take early warnings seriouslyand act upon them as soon as they are presented.

Full textAbstract:
My thesis installation emerged from an interest in visualizing breath. The resulting work came to exist at the intersection between art, biology, and performance.
The unicorn tapestries were used as a generative point of departure to explore the preservation and transformation of images through time, by time, and with time. Reproductions of the six tapestries were each etched into paper and then submerged into solutions of Phenol Red dye, Ferric Ferrocyanide (also known as Prussian Blue), and various forms of sodium chloride. Exhaled breath was used to encrust these images of the tapestries into physical objects which gradually crystallized and changed colors in response to viewers within the surrounding space. An invasive plant species native to Richmond, Virginia was utilized as a catalyst to re-absorb Carbonic acid from exhaled breath and convert the objects back to their original (or not so original) states. The final piece became the active remnants from an inquiry which quickly snowballed into so much more than I had initially planned.
The following text is written as a supplemental reading to trace some of my influences at the periphery of the piece while mapping my thought processes.

Full textAbstract:
En vue d’éviter ou de diminuer l’importance des dégâts causés par les accidents majeurs, il convient de modéliser les fonctions et les relations entre les composants d’un système industriel. Pour cela, dans cette thèse, on utilise la démarche de modélisation par la méthode STAMP (Systems-Theoretic Accident Model and Processes) pour représenter la structure hiéarchique du système, ainsi que les mécanismes de contrôle nécessaire pour préserver la sécurité d’un processus industriel. Afin de traiter les problématiques liées aux contrôles de la sécurité industrielle, on propose l’utilisation de l’outil de simulation Anylogic. Cet outil, permet modéliser et de simuler le comportement du système en fonction du temps en mode normal et en mode dégradé.L’objectif de ces travaux est donc de proposer une démarche basée à la fois sur la modélisation et la simulation pour analyser les risques et prévenir les accidents d’un site de stockage et distribution de GPL (Gaz Pétrole liquéfié)System thinking concepts and simulation tools are used to model the risk prevention plan and operational modes designed to enforce safety constraints at a French liquefied petroleum gas (LPG) storage and distribution facility. In France, such facilities are classified and the subject of special legislation and safety regulations. Their supervision is the responsibility of a control and regulatory body. A technological risk and prevention plan is provided, where all the dangerous phenomena likely to occur in addition to the safety control measures are listed in the safety report. Safety is therefore addressed through rules, and control mechanisms ensure that the system complies with safety constraints. Taking this facility as a case study, we use the STAMP theoretical framework together with AnyLogic simulation software to model technical elements and human and organizational behavior. We simulate how the system evolves over time and the strategies that are deployed in a loss of control scenario. The aim is to assess whether the prescribed safety program covers all of the system's phases; namely operations and audits. The results enrich other research that focuses on the contribution of system dynamics to risk analysis and accident prevention

Full textAbstract:
Class of 2011 AbstractOBJECTIVES: To assess the risk and return of publicly traded health insurance companies from 1986 through 2010. METHODS: Risk and return was assessed on these companies by identifying them with SIC 6231 and 6234 (Accident and Health Insurance and Medical Service Plans) along with their presence on the CRSP database. Risk and return was analyzed via alpha and beta for SIC 632x, which were calculated utilizing the CAPM, Fama-French 3 Factor and Carhart 4 Factor econometric models. Risk and return was further assessed by calculating a Sharpe ratio along with determining annualized mean excess return and volatility for SIC 632x and the overall market. Lastly, cumulative price paths for both SIC 632x and the overall market were calculated and a Monte Carlo simulation analysis in Matlab and Microsoft Excel was run to simulate 6500 portfolios to compare risk to return ratios for SIC 632x over the time period of 1986-2010 versus the time period of 2006-2010. RESULTS: Overall, 110 companies were identified with SIC 6321 and 6234 and 7938 observations were made. The results were reported in a cross sectional format with five time periods of five years each (1986-1990, 1991-1995, 1996-2000, 2001-2005, and 2006-2010 respectively). The descriptive statistics showed that SIC 632x had a higher rate of return than the overall market (1.21±14.15 compared to 0.88±4.49; however, they also had greater risk (0.89±14.15 vs 0.57±4.48). The CAPM model captured an overall alpha value of 0.44 while the 3 Factor model provided an overall alpha of -0.20 and the 4 Factor model provided an overall alpha of 0.31. The 4 Factor model had the highest overall r-squared value of 0.16. The overall annualized mean excess return was greater for SIC 632x than the overall market (10.71% vs 6.80%) while the volatility was also greater (20.30% vs 16.17%). Additionally, the Sharpe ratio was calculated and was greater overall for SIC 632x than the overall market (0.53 vs 0.42). Graphically, cumulative asset price paths were illustrated for both SIC 632x and market-based portfolios along with a mean variance efficient frontier for the SIC 623x portfolio set during the time periods of 1986-2010 and 2006-2010. These figures showed increased return for SIC 632x compared to the overall market while illustrating increasing risk and return rate trends for SIC 632x within the sector itself. CONCLUSION: Publicly traded companies providing accident and health insurance and medical service plans possess securities that have potentially higher returns but potentially higher risk relative to the overall market. Furthermore, the findings via the alpha, Sharpe ratio and Efficient Frontier simulation illustrated that the overall market provides a similar risk to return ratio compared to that of the analyzed companies in this study.

Full textAbstract:
Road safety is a major issue affecting the road sector. Road accidents remain a serious impediment to sustainable human development in many of the developing member countries (DMCs) of the Asian Development Bank (ADB). Road accidents continue to be an important social and economic problem in developing countries like India. Growth in the number of motor vehicles, poor enforcement of traffic safety regulations, poor quality of roads and vehicles, and inadequate public health infrastructures are some of the road safety problems facing in India.
The object of this Thesis is to present a status report on the nature of the government policy towards the Activity plans implemented till now and which has to be implemented later for the reduction of road fatalities and for the safe roads, and also giving the guidelines for financing of remedial measures, institutional framework, physical characteristics of the road, traffic control and calming measures, road safety education and enforcement issues.
The aim of the Activity plans is to analyze the present situation of road safety in India and to indicate main problems in individual sector of the Activity implemented by comparing and taking the examples of some of the ASEAN Region who are successed in implementing in the individual sectors. The effect of the programme to real safety situation is estimated, and further plans could be corrected if it is necessary. Implementation of the goals for the coming years to reduce the number of accidents at maximum extent and give people, the safe and the steady flow of traffic in India. The vision of a tremendous change next 5 to 10 years is based on a big potential for improvement and a joint effort of all involved groups on all levels of traffic safety, centrally coordinated by the National Road Safety Authorities.
The Action Plan is deliberately divided into 14 key Sectors of activity in broadly the same way as the individual country road safety action plans. The sectors involve many different disciplines and a very wide range of multi sector activities but all are based on applying scientific, methodical approaches to the problem. At the end the thesis gives the recommendations and conclusion for the safe Roads in India

Full textAbstract:
Ce travail s'est intéressé à la réponse du membre pelvien, l'une des premières parties corporelles touchées, dans des configurations d'impact impliquant l'usager vulnérable non motorisé (piétons et cyclistes). Un modèle éléments finis biofidèle du membre pelvien (modèle LLMS) a été utilisé pour reproduire, dans un premier temps, des essais fractionnés (impacts latéraux sur la jambe fléchie). Des corrélations entre le modèle et les expérimentations, sur la cinématique, les accélérations et le bilan lésionnel, a permis de vérifier, au moins qualitativement, la cohérence du modèle numérique. Un impact (cycliste heurté latéralement par un véhicule à 32 km/h), basé sur une expérimentation, a également été reproduit avec le modèle éléments finis. Les résultats numériques, comparés aux données expérimentales, ont montré de bonnes concordances. De nouvelles configurations d'impact (cycliste et piéton) ont été simulées. Ainsi, une étude paramétrique sur le véhicule (géométrie, vitesse) et, le cas échéant, sur le cycliste (vitesse, position) ont mis en évidence les situations les plus défavorables, suivant les lésions, pour l'usager vulnérable considéré. Les principaux mécanismes de blessure du membre pelvien, le cisaillement et la flexion latérale, ont été quantifiés au niveau du genou. Les différentes configurations d'impact ont permis d'établir, pour ces deux mécanismes, des critères lésionnels. Ainsi, pour une situation d'impact considérée, les niveaux de cisaillement et de flexion latérale au-delà desquels le membre pelvien de l'usager vulnérable est touché ont ainsi pu être évaluésIn accidents implying vulnerable road users, the lower limb is one of the most injured body areas. Therefore, this work is focused on the lower limb response in such impacts. A biofidelic finite element model (LLMS model) was first used to reproduce experimental tests that consisted of lateral impacts on the leg. Computed accelerations, kinematics and injuries were compared against experimental data. Good correlations were showed from a qualitative point of view. Based on an experimental configuration (lateral impact, car velocity 32 km/h), a car-bicycle impact was then simulated. The computed lower limb response was consistent with the experimental one. New impact configurations were studied for car-bicycle and car-pedestrian impacts. Parameters of the car (velocity, shape) and the posture of the cyclist (knee flexion) were modified to analyse the most critical conditions for vulnerable road users. The main injury mechanisms (shearing and lateral flexion) of the lower limb in such impact situations were quantified. Injury thresholds were estimated for all the tested configurations. In the present simulated car-bicycle and car-pedestrian impacts, levels of shearing displacement and lateral flexion angle leading to knee injury were evaluated

Garoo utiliza los conceptos de los videojuegos para entregar una experiencia educativa cautivante y efectiva a través de una aplicación para smartphones. Garoo opera primeramente en la industria de Educación/ChildCare. Estados Unidos tiene una tasa de mortalidad infantil baja pero debido a su población total eso significa más de 25.000 muertes al año. Por otro lado, existen más de 44 millones de padres con hijos menores a 5 años, de ellos más de un 70% tiene acceso a un Smartphone el cual usa diariamente. Las aplicaciones actuales apuntan a temas muy amplios como primeros auxilios, Cruz Roja y St. Johns son ejemplos de esto, o temas muy específicos como embarazo y desarrollo cognitivo. Para obtener clientes, Garoo extenderá su comunidad de padres existente para Estados Unidos en las principales redes sociales como Facebook, Instagram, Twitter. En ellas es posible identificar a más de 6,8 millones de personas por medio de publicidad. Por otro lado, se utilizará una estrategia de contenidos como fuente de contactos de manera orgánica para generar un efecto de red al entregar contenidos de calidad que sean compartidos de manera orgánica. Se necesitarían $115.000 dólares para financiar este plan de negocios hasta el punto de quiebre. En el primer año operando se espera obtener ventas por $180.000 dólares con gastos de $225.000 dólares. Para el tercer año de operación se espera incrementar las ventas hasta $7,62 millones de dólares con $4,85 millones de dólares en gastos.

Full textAbstract:
Las secuencias de accidente con rotura de tubos en el generador de vapor (secuencias SGTR) están consideradas como contribuyentes del riesgo en reactores de agua a presión. Su relevancia radica en la potencial liberación de aerosoles radioactivos al medio ambiente en caso de accidente severo. Sin embargo, dichas partículas podrían quedar retenidas parcial o totalmente sobre las superficies del generador de vapor, incluso en condiciones extremas de ausencia de agua en el generador de vapor. La carencia de conocimiento en cuanto a la capacidad de retención de término fuente de este componente ha eludido su consideración en los estudios probabilistas de seguridad y en las guías de gestión de accidente severo.
Esta tesis es una contribución a la comprensión y cuantificación de los procesos naturales de mitigación que tienen lugar dentro del generador de vapor como consecuencia de los accidentes SGTR. La principal actividad llevada a cabo ha sido el desarrollo de un modelo teórico que calcula la capacidad de retención de aerosoles en la etapa de rotura de un generador de vapor seco. El modelo, llamado ARI3SG, está basado en una aproximación de filtro y tiene una naturaleza semi-empírica. En él se tienen en cuenta tanto la dinámica de aerosoles como la hidrodinámica de aerosoles que tiene lugar dentro del generador de vapor en este tipo de escenarios. Para esto último, se han llevado a cabo una serie de simulaciones con el código tridimensional FLUENT 6.2, que han sido validadas con datos experimentales.
El comportamiento del modelo ha sido evaluado en profundidad: primero, a través de un proceso de verificación con el que se ha visto que es robusto. Segundo, a través de un proceso de validación frente a los datos experimentales disponibles. Tercero, a través del estudio del efecto de las incertidumbres del escenario y del modelo sobre los resultados.
La comparación frente a los datos experimentales ha sido satisfactoria y muestra la viabilidad del uso de formulaciones como la de ARI3SG en

Full textAbstract:
Aim: The current research aimed to study the association between exposure to low-dose radiation fallout after the Chernobyl accident in 1986 and the incidence of cancer in Sweden. Methods: A nationwide study population, selecting information from nine counties out of 21 in Sweden for the period from 1980 – 2010. In the first study, an ecological design was defined for two closed cohorts from 1980 and 1986. A possible exposure response pattern between the exposure to 137Cs on the ground and the cancer incidence after the Chernobyl nuclear power plant accident was investigated in the nine northernmost counties of Sweden (n=2.2 million). The activity of 137Cs at the county, municipality and parish level in 1986 was retrieved from the Swedish Radiation Safety Authority (SSI) and used as a proxy for received dose of ionizing radiation. Information about diagnoses of cancer (ICD-7 code 140-209) from 1958 – 2009 were received from the Swedish Cancer Registry, National Board of Health and Welfare (368,244 cases were reported for the period 1958 to 2009). The incidence rate ratios were calculated by using Poisson Regression for pre-Chernobyl (1980 – 1986) and post-Chernobyl (1986 – 2009) using average deposition of 137Cs at three geographical levels: county (n=9), municipality (n=95), and parish level (n=612). Also, a time trend analysis with age standardized cancer incidence in the study population and in the general Swedish population was drawn from 1980 – 2009. In the second study, a closed cohort was defined as all individuals living in the three most contaminated counties in mid-Sweden in 1986. Fallout of 137Cs was retrieved as a digital map from the Geological Survey of Sweden, demographic data from Statistics Sweden, and cancer diagnosis from the Swedish Cancer Registry, National Board of Health and Welfare. Individuals were assigned an annual 137Cs exposure based on their place of residence (1986 through 1990), from which 5-year cumulative 137Cs exposures were calculated, accounting for the physical decay of 137Cs and changing residencies. Hazard ratios for having cancer during the follow-up period, adjusted for age, sex, rural/non-rural residence, and pre-Chernobyl total cancer incidence, were calculated. Results: No obvious exposure-response pattern in the age-standardized total cancer incidence rate ratios could be seen in the first study. However, a spurious association between the fallout and cancer incidence was present, where areas with the lowest incidence of cancer before the accident coincidentally had the lowest fallout of cesium-137. Increasing the geographical resolution of exposure from the average values of nine counties to the average values of 612 parishes resulted in two to three times higher degree of variance explanation by regression model. There was a secular trend, with an increase in age standardized incidence of cancer from 1980 – 2009. This trend was stronger in the general Swedish population compared to the nine counties of the present study. In the second study, 734,537 people identified were divided into three exposure categories: the first quartile was low exposure (0.0 to 45.4 kBq/m2), the second and third quartiles were intermediate exposure (45.41 to 118.8 kBq/m2), and the fourth quartile was highest exposure (118.81 to 564.71 kBq/m2). Between 1991 and 2010, 82,495 cancer cases were registered in the three counties. Adjusted HRs (95% CI) were 1.03 (1.01 to 1.05) for intermediate exposure, and 1.05 (1.03 to 1.07) for the highest exposure, when comparing to the reference exposure. Conclusion: Using the ecological data, there was no exposure response trend; however, after refining the data to the individual level of exposure, there was an overall exposure response pattern. Nonetheless, due to the time dependency, these results were restricted to the age group of 25 – 49 among males. Using register-based data only, for determining the association between low-dose exposure to radiation and the risk of developing cancer, is difficult since we cannot control for other significant factors that are associated with cancer.

Collimator and shield configurations for two high-purity germanium detectors were designed for use during a loss of coolant accident at a boiling water reactor. The detectors will return information concerning stack releases to operators within a 15 minute time frame. Operating parameters for the stack monitors are defined by the United States Nuclear Regulatory Commission (USNRC) and a 24 hour source term generated by ORIGEN2. A lead collimator 0.4 cm in diameter, 20 cm in length for the high range detector and 2 cm in diameter, 20 cm in length for the low range detector was shown through a Monte Carlo code, MCNP4 to prevent high range detector saturation and provide enough low range detector response so good statistical data on stack releases result. A lead shield 20 cm thick was shown through MCNP4 to reduce the background radiation interference for both detectors to levels such that the detection of isotopes within the stack effluent is possible as required by the USNRC.

Esta dissertação refere-se a um estudo exploratório dos riscos de acidentes ampliados no Pólo Industrial de Camaçari bem como das vulnerabilidades do seu entorno. Para tanto realizou-se uma análise do planejamento urbano no entorno do Complexo Petroquímico de Camaçari, quanto aos aspectos protecionais existentes no Plano Diretor de Desenvolvimento Urbano - PDDU do Município de Camaçari, frente aos riscos desses acidentes. Realizou-se também uma análise das vulnerabilidades daquele município, indicando estratégias de conhecimento e minimização dos danos pós-sinistros, causados por acidentes ampliados gerados pelas empresas do Pólo. Promoveu-se, ainda uma analise, junto ao Instituto do Meio Ambiente - IMA do plano de contingência do Pólo, denominado pelo Comitê de Fomento Industrial de Camaçari - COFIC como “PROJETO APPOLO II”. Efetuou-se uma pesquisa bibliográfica sobre os principais acidentes ampliados ocorridos no Brasil e no mundo, um levantamento histórico dos acidentes ocorridos no Pólo e catalogados pelo Conselho Consultivo de Camaçari e uma análise das vulnerabilidades da defesa civil de Camaçari. As análises do PDDU, do Projeto Appolo II e as observações in locco concluíram que: 1) há riscos para a população da sede daquele município dado a proximidade do Pólo, 2) a Defesa Civil de Camaçari não está munida de equipamentos e sistemas protecionais necessários e adequados a situações de enfrentamento dos riscos de acidentes ampliados; 3) não há um plano de contingência para a população da sede do município de Camaçari.Como resultado este trabalho sugere a elaboração de um plano de contingência para o município de Camaçari e outras medidas no sentido de suprir as deficiências constatadas.

I fattori umani e organizzativi svolgono un ruolo chiave nella prevenzione e mitigazione di incidenti rilevanti. La Quantitative Risk Analysis (QRA), considera come cause di incidente solamente i fattori tecnici. Dunque è possibile integrare questa analisi con tecniche per Human Reliability Analysis (HRA), ma la loro applicazione è ancora limitata al settore nucleare. Inoltre, la staticità della QRA ha costruito le basi per la valutazione dinamica del rischio. Nel presente lavoro, è stato considerato un generico impianto di produzione di ammoniaca, per il
quale è stato creato un database di incidenti
e near misses che ha mostrato come i fattori umani rappresentano la seconda causa di incidenti. Successivamente è stato considerato come caso di studio rappresentativo la rottura catastrofica di un serbatoio di stoccaggio di ammoniaca avvenuta in Lituania nel 1989, al quale è stata
eseguita una bow-tie analysis per identificare le cause della rottura e le barriere di sicurezza coinvolte. In seguito, tre metodi per l’analisi dei fattori umani e organizzativi sono stati applicati al caso di studio. Il metodo REWI (Early Warning Indicator), basato sul concetto di resilienza, stabilisce una serie di indicatori il cui monitoraggio periodico può contribuire alla gestione del rischio in maniera proattiva. Il metodo Petro-HRA
è una tecnica innovativa per la Human Reliability Analysis sviluppata per l’industria petrolchimica. Essa fornisce un metodo sistematico per valutare i fattori umani e
organizzativi attraverso una procedura dettagliata. Infine il metodo TECnical Operational and Organizational factors (TEC2O) per la valutazione dinamica del rischio. Questo metodo considera fattori tecnici, umani e organizzativi, combinando i vantaggi dei metodi HRA con le caratteristiche dinamiche e di resilienza della metodologia REWI. Il suo risultato mostra una valutazione del rischio più completa e realistica e consente di identificare le caratteristiche di ciascun metodo trattato.

Full textAbstract:
In this study, following a severe accident at Kozloduy nuclear plant in Bulgaria how Turkey would be affected was investigated. The severe accident refers to core meltdown accident with catastrophic failure of containment. The model used is HySPLIT model developed in America. The worst day was predicted considering deposition of radionuclides. For initial runs, accidental release of I-131 and Cs-137 radionuclides was modeled for each day of year 2000 to find the worst day, seen to result from release beginning on April 7th 2000. After modeling release of all radionuclides for the worst day, radiation dose at different receptors, 12 most populated cities over Turkey has been calculated via different pathways. Late effects, fatal cancer, non-fatal cancer and hereditary risks, has been investigated for these receptors. The mostly affected part of Turkey was Marmara region and fatal cancer risk therein was 7x10-2 %. The collective health risk throughout Turkey was approximately 20 600 people. The same approach was then applied for investigating health risk of proposed nuclear reactor at Akkuyu, Turkey. In this case, the worst day was resulted from release beginning on 21st of February 2000. The worst affected part was the narrow strip in Central Anatolia extending to the north-eastern cost and fatal cancer risk in this region was 3.4x10-1 %. The collective health risk over Turkey was approximately 30 600 people. The results showed that Kozloduy nuclear plant has dominating effect throughout Turkey, but proposed Akkuyu reactor affects very limited region.

Les navires à passagers sont sensibles à un chavirement rapide dû à l’entrée soudaine de l’eau lors d’accidents maritimes. Durant et après la création de l’endommagement, le navire envahi peut souffrir de phases intermédiaires très dangereuses, qui risquent éventuellement de le détruire. Une investigation expérimentale utilisant la section centrale du navire à passager PRR02 – ITTC/SiW a été menée afin de déterminer les facteurs influençants ainsi que la manière dont ils interagissent entre eux. De plus, elle a pour but d’améliorer la compréhension de la physique de l’envahissement et de vérifier si l’investigation de ce type de navire est adéquate en eau calme. Une méthode innovante en ingénierie océanique, celle des Plans d’expériences (DOE), est utilisée pour planifier et conduire les tests, ainsi qu’analyser leurs résultats. Durant les phases intermédiaires d’envahissement, l’eau et l’air interagissent fortement entre eux et influencent le comportement du navire lui-même. Cette interaction est mise en évidence par la détection de trois pics importants des réponses. De plus, la présence de hautes et basses fréquences est observée dans le compartiment des machines. Ceci dépend de la compressibilité de l’air, et le ballotement de l’eau à l’intérieur de ces compartiments. Les tests confirment que le coefficient de décharge n’est pas constant pendant l’envahissement et ils l’évaluent expérimentalement. En se basant sur un plan factoriel d’expérience, un modèle mathématique caractérisant l’envahissement a été construit, validé, puis optimisé. Il met en évidence, pour le cas d’endommagement par le coté de ce type de navires, une influence marquée de la surface d’ouverture, de l’excitation externe, du tirant d’eau, ainsi que du temps de création de l’endommagement. La géométrie du compartiment des machines (disposition des blocs et perméabilité) a relativement peu d’influence. Les paramètres relatifs à l’air (envahissement transversal et niveau de ventilation) ont assez peu d’influence dans ce cas. Cette étude démontre l’utilité et l’efficacité de la méthode DOE. Elle construit la base d’élaboration d’une nouvelle procédure pour étudier la survivabilité des navires à passagers durant et après avarie. De plus, les modèles théoriques et les codes numériques pourront profiter des résultats obtenus afin d’améliorer leurs performancesRoll-On/Roll-Off passenger vessels appear to be sensitive to rapid capsizing due to abrupt ingress of water caused by maritime accidents. As a result of the damage creation, the flooded ship can experience transient and progressive flooding phases (Intermediate Flooding Stages, IFS) which might be more devastating than the final condition, as the sudden loading could significantly alter the ship stability characteristics. An experimental investigation using the midsection of the PRR02 – ITTC/SiW Ro-Ro passenger ferry is undertaken to determine the influential factors within the IFS, and to reveal their individual influence, as well as their interactions. More importantly, it is devoted to hopefully provide profound insight into the flooding physics and look over the adequacy of the calm water condition to assess the IFS of such vessels. A novel-in-ocean-engineering methodology, the Design of Experiments (DOE), is used to plan systematic model tests, perform them, and analyze their results. During the IFS, a strong interaction is found between, on one hand, both implicated fluids, i. E. Water and air, and, on the other hand, the model geometry and behavior. The detection of three conspicuous peaks highlights this interaction. Moreover, a two-fold behavior is observed in the Engine Room partially submerged. These behaviors are drawn by the air compressibility, the water surface, as well as the sloshing occurring inside this room. The tests confirm that the discharge coefficient for realistic flooding situations is not constant during the flooding, and estimate it experimentally. Besides, a mathematical model characterizing the IFS is successfully built, then optimized. Regarding the global behavior of such vessels suffering from side damages, it is pointed out that the Damage Opening area, the external excitation, the initial draught, and the duration of damage creation most affect the IFS; then Engine Room-related parameters (permeability and layout) come with a relatively less influence. A relatively very little influence is found for Air-related parameters (cross-flooding and air-ventilation level). This study demonstrates the validity and efficiency of applying the DOE methodology in Damaged Survivability Domain, and establishes a suitable basis to elaborating a novel assessment procedure based on ‘interactive research’ to reliably assess the damaged survivability of such vessels. Furthermore, theoretical models and numerical codes can benefit of its achievements to improve their performance and credibility

Accident is a metaphor for life. From an arbitrary point in time, we potentially preview the entirety of existence. There is a Chinese idiom called “ blessing or bane,” which implies that a misfortune may perhaps soon turn into a blessing. Focusing on accident as a design method implies making the best out of a bad situation. An accident reveals invisible circumstances and potentialities in the world, both familiar and unfamiliar. Looking into the unpredictable world, I can begin to release my control, take a breath, and see what might happen if I do not fight the situation. I am able to get out of my own way, and see what the work’s destiny will be. This sets up a context in which there are no faults, no mistakes, and no accidents — everything may contribute to a solution.

Full textAbstract:
Motor vehicle speed is a key risk factor contributing to many road accidents. Historical data shows that speed-related accidents account for a significant proportion of all the fatal and serious injury accidents and result in considerable social and economic costs. The objective of this thesis is to understand and quantify the relationship between traffic speed and accident frequency at urban signalized intersections in the city of Edmonton and Vancouver, Canada. This objective is achieved by developing accident prediction models which relate accident frequency to speed variables and other intersection characteristics. Road accident, traffic speed, traffic flow and road geometric data were obtained from the two cities for the purpose of the models development. The generalized linear modelling techniques are used to develop the accident prediction models assuming negative binomial error structure. A total of 15 models are developed relating accident frequency with five speed variables: average speed, mode speed, 85th percentile speed, speed standard deviation and percent of vehicles speeding. The results show that all five speed variables are positively correlated with accident frequency. A quantitative relationship between the change in the value of speed variables and the change in accident frequency is derived from the developed models.

L'instabilité des ouvrages souterrains est une cause importante d'accidents tant pendant leur réalisation que pendant leur exploitation. La rétro-analyse d'accidents passés est l'une des méthodes permettant d'améliorer la prévention de tels accidents ainsi que la conception et le dimensionnement des nouveaux projets. Une recherche bibliographique a permis d'établir une base de données de cas d'accidents rencontrés dans les ouvrages souterrains à travers le monde. Ces cas, actuellement au nombre de 230, concernent les phases de construction et d'exploitation d’ouvrages, chaque cas étant caractérisé par plusieurs variables associées aux phénomènes d'instabilité et aux caractéristiques géométriques et géomécaniques de l’ouvrage. Les causes et les conséquences d’instabilités ont été également analysées dont celles liées au contexte géologique et en particulier aux caractéristiques géotechniques des terrains traversés. Cette base de données a permis d’effectuer plusieurs analyses sur les instabilités des ouvrages dont la plus importante est une analyse factorielle de correspondances qui a éclairé les liaisons entres les phénomènes d’instabilités et les différentes modalités de ses variables explicatives.

Experience feedback of previous accidents is one of used methods that allows improving the prevention of such accidents during the design and the construction of new underground works projects. A bibliographical search enabled us to establish a database of tunnels and underground constructions accidents in the world. These database contains currently 230 case related to the two phases of construction and exploitation of underground constructions, each case was characterized by several variables associated to instability phenomena, to geometrical and géomechanicals characteristics of the concerned underground construction. The causes and the consequences of instabilities phenomena were also analysed especially those related to the particular geological context and the géotechnical characteristics of the surrounding ground. The established database enabled us to carry out several analyses on instabilities phenomena like as a factorial correspondence analysis, which aims to discover the relations between instabilities phenomena and their explanatory variables. This study proposes two representative numerical models of vaulted tunnels supported by masonry structure. Biased on the numerical simulation and the experimental design technique, it also relates to the analysis of the mechanical behaviour of the masonry structure support and its evolution in the time, where the influence of certain mechanical parameters of masonry structure was quantified and evaluated by various analyses methods such as multivariate variance analysis and the linear modelling by multiple regression

Thesis (MDF)--Stellenbosch University, 2006.ENGLISH ABSTRACT: In Southern Africa only five countries administer a fuel levy funded motor vehicle accident compensation system. These are South Africa, Namibia, Swaziland, Botswana and Lesotho. These accident compensation systems are administered by statutory bodies established through the respective Act of Parliaments, with the exception of Lesotho, which is outsourced to a private insurance agency for administration purposes. The enabling legislation prescribes the compensation of accident victims, where the cause of accident is due to the negligent or fault of the driver or owner of the vehicle. Over the years, the administration of these Funds have proven to be a significant challenge in respect of their enabling legislations, inadequate funding levels to meet liabilities as prescribed by the respective legislation and poor public governance of the institutions. The study reviews the Namibian MVA Fund's efforts to reform the compensation scheme in the context of an overall public management reform and social policy. The study presents the historical overview of the accident compensation regime and how that has influenced the current thinking and application of compensation policy in the Southern African region. The study emphasised the quest of the Funds to become financially viable, thus being able to meet present and future liabilities as and when they accrue to the respective Funds. Thus it presents new thinking and knowledge on alternative revenue sources that could be further explored to enhance financial viability and broadening the scope of coverage of the compensations scheme.
AFRIKAANSE OPSOMMING: In Suidelike Afrika gebruik slegs vyf lande 'n stelsel vir die vergoeding van motorvoertuigongelukke wat deur 'n brandstof heffing befonds word. Hierdie lande is Suid Afrika, Namibie, Swaziland, Botswana en Lesotho. Hierdie ongeluksvergoedingstelsel word ge-administreer deur statutere liggame daargestel deur die onderskeie wetgewing van Parlemente, met uitsondering van Lesotho, wat die funksie uitgekontrakteur het aan 'n private versekeringsmaatskapy vir adminstrasie doeleindes. Die betrokke wetgewing skryf die vergoeding van ongelukslagoffers voor waar die oorsaak van die ongeluk deur die nalatigheid of fout van die bestuurder of eienaar van die voertuig is. Die administrasie van die onderskeie fondse oor die jare, het getoon dat 'n groot uitdaging gestel word aan hul magtigende wetgewing ten opsigte van die toereikendheid van fondse en swak beheer, soos voorgeskryf deur die betrokke wetgewing. Hierdie studie hersien die Motorvoertuigongeluksfonds van Namibie se strewe tot die hervorming van die vergoedingskema in die oorhoofse publieke bestuurshervorming en maatskaplike voorskrifte. Die studie verteenwoordig die historiese oorsig van die ongeluksvergoedingskema en die invloed daarvan op die huidige denkwyses en toepassing van vergoedingskemas in die Suider-Afrikaanse streke. Hierdie studie het die proses van die Fondse om finansieel lewensvatbaar te word beklemtoon, derhalwe om in staat te wees om die huidige en toekomstige finiansiele verantwoordelikheid soos en wanneer dit deur die onderskeie fondse toegeskryf word, na te kom. Gevolglik verteenwoordig dit nuwe denkwyses en kennis van altematiewe bronne van inkomste wat verder ondersoek kan word om finansiele lewensvaatbaarheid te verbeter en die voordele struktuur van hierdie vergoedingskemas te vergroot.

Accidents initiated by a natural hazard or disaster which result in the release of hazardous materials are commonly referred to as Natech (Natural Hazard Triggering a Technological Disaster) accidents.
The conditions brought about by these kinds of events are particularly problematic, the presence of the natural event increases the probability of exposition and causes consequences more serious than standard technological accidents.
Despite a growing body of research and more stringent regulations for the design and operation of industrial activities, Natech accidents remain a threat. This is partly due to the absence of data and dedicated risk-assessment methodologies and tools. Even the Seveso Directives for the control of risks due to major accident hazards do not include any specific impositions regarding the management of Natech risks in the process industries. Among the few available tools there is the European Standard EN 62305, which addresses generic industrial sites, requiring to take into account the possibility of lightning and to select the appropriate protection measures. Since it is intended for generic industrial installations, this tool set the requirements for the design, the construction and the modification of structures, and is thus mainly oriented towards conventional civil building.
A first purpose of this project is to study the effects and the consequences on industrial sites of lightning, which is the most common adverse natural phenomenon in Europe. Lightning is the cause of several industrial accidents initiated by natural causes. The industrial sectors most susceptible to accidents triggered by lightning is the petrochemical one, due to the presence of atmospheric tanks (especially floating roof tanks) containing flammable vapors which could be easily ignited by a lightning strike or by lightning secondary effects (as electrostatic and electromagnetic pulses or ground currents).
A second purpose of this work is to implement the procedure proposed by the European Standard on a specific kind of industrial plant, i.e. on a chemical factory, in order to highlight the critical aspects of this implementation. A case-study plant handling flammable liquids was selected. The application of the European Standard allowed to estimate the incidence of lightning activity on the total value of the default release frequency suggested by guidelines for atmospheric storage tanks. Though it has become evident that the European Standard does not introduce any parameters explicitly pointing out the amount of dangerous substances which could be ignited or released. Furthermore the parameters that are proposed to describe the characteristics of the structures potentially subjected to lightning strikes are insufficient to take into account the specific features of different chemical equipment commonly present in chemical plants.

Cette recherche porte sur la prévention des Accidents de Plain-Pied (APP) survenant en situation professionnelle, accidents très fréquents et parfois très graves. Face à la difficulté de faire diminuer ces accidents en adoptant une démarche qui se base sur l’analyse d’accidents, nous nous orientons vers l’étude ce qui dans l’activité des opérateurs contribue à la survenue de ces accidents mais également à leur non survenue. En effet, la plupart du temps, les opérateurs sont exposés à des facteurs de risque d’APP et n’ont pas pour autant d’accidents. Nous cherchons ainsi à comprendre la façon dont les opérateurs gèrent la sécurité de leurs déplacements en étudiant les systèmes de ressources, valeurs et contraintes qui influent sur leurs pratiques selon les classes de situations rencontrées. Nous proposons des actions n’allant pas seulement dans le sens d’une suppression systématique d’éléments ‘à risque’, d’autant plus que tous ces éléments ne peuvent être supprimés (ex. : escaliers), mais également des actions dirigées vers l’aménagement et la conception de situations capacitantes au plan de la sécuritéThis research is about the prevention of work-related Accidents On the Level (AOL), occupational slips, trips and falls that occur frequently and sometimes prove consequential. Decreasing accidents while adopting an approach based on accident analysis is difficult; therefore we look at what aspects of operators' activities contribute to the occurrence and absence of such occupational accidents. Indeed, for the majority of the time, operators are exposed to AOL risk factors but do not have an accident. We learn the safety practices operators take when walking about at their workplace by studying systems of resources, values and constraints that have influence on their practices, depending on the situations classes met. We propose that effective preventative measures are not only linked to systematic suppression of risk factors but also to the designs of facilitating environments planned around safety

Abstract That accidents cause countless property damage, injury, and death is too serious to ignore. Traffic enforcement is the part of traffic safety administration and plays the key role for improving the whole traffic safety. Most enforcement units and individuals recognize this fact. But, they don't "know how"? This research attempts to construct a traffic accident prevention enforcement-planning model to help them "know how". There are three sub-systems in this model. The first one is the Accident Data Analysis Sub-System. It can help the enforcement unit to choose useful traffic accident data for manpower allocation and duty assignment. The following sub-system is mainly for manpower allocation. This sub-system consists of two models including manpower allocation and the enforcement model. Based on the manpower allocation model will give a basis for traffic enforcement units regarding patrol precinct under the present number of policemen in the enforcement unit, how many policemen and work times are needed for daily traffic accident prevention, The enforcement model will help to arrange a duty schedule, to decide the enforcement target, to prepare suitable duty style and so on. The third one is the Evaluation Sub-System. The evaluation sub-system is comprised of six mathematical formulas and is organized as one synthetic formula. The synthetic formula is adaptable to traffic enforcement unit needs and characteristics. The evaluation sub-system will examine the process and result of enforcement activities to lead the direction of traffic accident prevention. At last, the entire traffic enforcement-planning model for accident prevention is evaluated by a case study; in addition, questionnaires are also conducted to a survey of enforcement program designers and basic officers. The case study uses one highway patrol squad as an example. The accident data, which happened in its jurisdiction, would be collected for the whole past year. The number of accidents is 530. Later, the case study designs the enforcement program by this new model. The survey questions are made up of differences between this new and traditional enforcement programs. The result of investigation can prove that the degree of acceptability is high. The new enforcement program model is able to function well and perform successfully in the future.

In the Taiwan region, there are over 0.3 million traffic accidents per year, which affects even million families. For those who doesn’t have sufficient insurance, the claims are always through public opinion representatives, local officials, or even the blackmailers. Generally, negotiating with the other party may leads conflicts or bullying, which is a burden of people. The reason is that the Taiwanese are lack of the knowledge of the liability and claim of car accident. The purpose of this study is to design a set of teaching plans related to car accident claims and teach the public. To understand the performance of teaching, questionnaire survey is conducted and the results are analyzed.According to the results, people can learn about the rights and obligations of the laws and procedures related to car accident claims. Also, through the lecture people can learn how to negotiate with the other party and how to settle the content of the settlement. The teaching plan and material can be applied to other regions so as to help people to reduce unreasonable compensation.

During early stage of a nuclear power plant accident, consideration of beyond design basis accidents is an essential component of the defense in depth approach to assure nuclear safety. The probability of occurrence of a beyond design basis accident is very low, but such an accident may lead to significant consequences. Taiwan's fourth nuclear power plants, the Lungmen nuclear power station (LNPS), which is an advanced boiling water reactor (ABWR) with fully digitized instrumentation and control (I&C) system is chosen as the target plant. The LNPS full scope engineering simulator is used to generate the testing data for method development. The following common initiating events are considered in this study: Loss of coolant accidents (LOCA), Loss of all feedwater (TLOFW), Loss of offsite power (LOOP), Station blackout (SBO). This study combines symptom-oriented and event-oriented approach for early warning and decision making. First, the Plant Damage States, which is symptom-oriented, identify the initiating event. It also gives the information of safety system‘s status. Initiating event and safety system‘s status are used in Event Tree (ET), which is event–oriented, to determine accident sequences by using probabilistic risk assessment (PRA) technique. With accident sequences, the core melt frequency is easy to be calculated. Studies have indicated that the combination of the symptom-oriented approach and the event-oriented approach can be helpful for nuclear power plant accident early warning and management.
