Signaled and Silenced Aspects of Nuclear Safety: A Critical Evaluation of International Nuclear Safety Thinking
2015
This article provides a critical analysis of safety-related assumptions and practices in international nuclear safety regulation, together with an overview of those aspects of safety that have been either signaled or silenced. The data consist of safety reports from the IAEA, OECD NEA and Western European Nuclear Regulators Association (WENRA), as well as from the national stress tests reports of the United Kingdom and Finland. For theoretical tools, we draw on the concept of a dominant co-operative scheme, and on some parts of Luhmann's Theory of Social Systems. The method is content analysis. We argue that the prevailing thoughts on safety by the international nuclear safety organizations…
Injury Evaluation in Teenage Cyclist-Vehicle Crash by Multibody Simulation
2014
Information on impact locations, impact situations and cyclist and pedestrian dynamics in impacts with passenger cars is fundamental for the development of effective solutions to improve cyclist and pedestrian protection. Accidentology research shows that cyclists typically have a higher impact location than the pedestrian, with a larger share of injuries from the windscreen area. Majority of accidents in Palermo, in the last years, happens at urban street (84%) that involve teenager (6.4%). In this paper simulation study captures dynamics and injuries to head and chest for teenager between a generic bicycle and a car model that is suitable for pedestrian or cyclist safety. Multibody simula…
Forensic mtDNA hair analysis excludes a dog from having caused a traffic accident
1999
A dog was suspected of having caused a traffic accident. Three hair fragments were recovered from the damaged car and subjected to DNA sequence analysis of the canine mitochondrial D-loop control region. The results were compared to saliva and hair samples from the alleged dog, as well as to control hair samples from four unrelated dogs of different breeds. Two sequence types exhibiting five nucleotide differences in a 377 bp fragment were identified among the four controls. Whereas the evidence hair fragment was identical to the type 1 control sequence, the alleged dog shared the type 2 control sequence except for one position. Thus the dog could be excluded as the origin of the hair fragm…
A comprehensive fracture prevention strategy in older adults : The European union geriatric medicine society (EUGMS) statement
2016
Published also in Aging Clinical and Experimental Research, Vol.28, No.4, WOS: 000379034800030 Prevention of fragility fractures in older people has become a public health priority, although the most appropriate and cost-effective strategy remains unclear. In the present statement, the Interest group on falls and fracture prevention of the European union geriatric medicine society (EUGMS), in collaboration with the International association of gerontology and geriatrics for the European region (IAGG-ER), the European union of medical specialists (EUMS), the Fragility fracture network (FFN), the International osteoporosis foundation (IOF) - European society for clinical and economic aspects …
Occupational exposure to home risk factors: analysis of physical and mental health condition of a group of Sicilian housewives
2016
INTRODUCTION: The work of housewives, in many ways, still lacks professional respect; particularly with respect to the neglect of exposure to risk factors such as: chemical, physical, biological, psychological and accidents. The purpose of this study is to analyze the possible impact of environmental risk factors on the physical and mental health of a group of Sicilian housewives. METHODS: We enrolled housewives living in Palermo and Catania and administered an anonymous questionnaire to obtain knowledge of three factors: (1) the habits of the respondents, (2) the type of house in which they lived and worked, (3) the diseases they suffered. We also administered them a hospital anxiety and d…
Dance movement therapy and falls prevention
2017
Falls are a leading cause of morbidity, healthcare use and mortality. Dance is a popular form of physical activity among older people and previous research has suggested that it may improve various health outcomes in this population, including balance, gait and muscle performance. A systematic review of the potential benefits of dance on falls and fear of falling is lacking. Thus, we conducted a systematic review considering all randomized controls trials (RCTs) investigating if dance can reduce falls and improve fear of falling in older adults. Major databases were searched from inception until 1 March 2017 and a total of 10 RCTs were identified, which included a total of 680 people (n = 3…
Das Krankheitsbild des doppelseitigen Carotisverschlusses
1974
An Hand von 10 eigenen Fallen wird das Krankheitsbild des doppelseitigen Carotisverschlusses dargestellt. Typische Verlaufsformen werden beschrieben. Am haufigsten sind: kontralaterale Hemiparese bei stummem einseitigem Verschlus, akute doppelseitige Symptomatik und langsam progrediente Hemisymptomatik. Die relativ geringe Bedeutung unblutiger Untersuchungsverfahren wird besprochen, nur die Angiographie kann die Diagnose sichern. Im klinischen Bild sollten auch diskrete beidseitige Symptome, ungewohnlich ausgepragte psychische Ausfalle oder auch eine verzogerte Ruckbildung der Ausfalle nach einem Insult an die Diagnose denken lassen. Die verschiedenen therapeutischen Konsequenzen werden bes…
Hazards That Can Affect CNC Machine Tools during Operation—An AHP Approach
2020
CNC (computer numerically controlled) machine tools are highly advanced technological systems, used to machine parts by means of metal cutting processes. Their structure and kinematics are very complex, involving accurate coordinated motions on three to five axes. Operating CNC machine tools is a complicated process, which can easily be affected by errors. Nowadays, safety systems and devices are developed in order to make this process safer and more user friendly. Modern CNC controllers are designed to deal with obvious sources of hazards, such as overloads (by means of various sensor systems) and collisions (by checking the NC code syntax and simulating it on the machine). However, despit…
Death of a 23-year-old man from cardiac conduction system injury through a blunt chest impact after a car accident.
2014
Abstract Cardiac contusion, usually caused by blunt chest trauma, has been recognized with increased frequency over the past decades. Traffic accidents are the most frequent causes of cardiac contusion resulting from a direct blow to the chest. Myocardial contusion is difficult to diagnose; the clinical presentation varies greatly, ranging from a lack of symptoms to cardiogenic shock and arrhythmia. Although death is rare, cardiac contusion can be fatal. The authors report a case of death due to a cardiac conduction system injury from a blunt chest impact following a car accident. The autopsy showed no external signs of thoracic trauma, no evident rib or sternum fractures. A small sub-endoc…
Improving reliability of road safety estimates based on high correlated accidents counts
2007
Calibrating a safety performance function (SPF) with many years of accident data creates a temporal correlation that traditional model calibration procedures cannot deal with. It is well known that generalized estimating equations (GEE) models are able to incorporate trends into accident data and thus overcome difficulties in accounting for correlation; the usual application of GEEs to safety analysis uses robust (or sandwich) estimates of regression coefficients under the independence hypothesis for the working correlation matrix. This practice is justified by the robustness of the GEE procedure against misspecification of the response correlation structure. Nevertheless, with this method,…
