Nous sommes heureux de publier de larges extraits d'un article paru dans la Revue suisse de medécine militaire (Bâle, décembre 1972), et que celle-ci nous autorise aimablement à reproduire. L'auteur, colonel sanitaire de làarmée suisse et médecin-chef d'une zone territoriale, y expose ses idées personnelles sur la médecine de catastrophe et le recyclage dans des établissements formant le personnel médical, les auxiliaires spécialisés et les secouristes sanitaires. Or, ce sujet est de nature, sans doute, à intéresser nos lecteurs. Car la Croix-Rouge se trouve confrontée aujourd'hui à des problèmes de secours en masse et, lors de conflits ou à la suite de désastres naturels, les problèmes de médecine et de chirurgie viennent au premier plan et Us concernent aussi Men les mèdecins que les infirmiers et secouristes, dont certains travaillent sous le signe de la croix rouge, du croissant rouge ou du lion-et-soleil rouge (Réd.).

Medical practice in disaster relief has a very specific aspect as compared with medicine in general, but I must point out that the difference lies in its organization rather than in its therapeutic nature. A doctor who has before him a sick or wounded person, or any other patient, will unstintingly provide care according to the knowledge and training he received at medical school. He will do so in accordance with the code of ethics of his calling, inculcated by his throughout the world draw inspiration from the Hippocratic Oath, the Prayer of Maimonides or the Geneva Declaration. All of this has been accepted and need not enter the type of training which we are about to define. The same applies to nurses and to the doctor's specialized auxiliaries, who are adequately trained for their occupation, in similar yet differentiated fashion.

Die erreichbare Genauigkeit von Werkzeugmaschinen hängt unter anderem von den Bedingungen am Aufstellort ab, wobei die Temperatur aufgrund ihres Jahres- und Tagesgangs sowie weiterer externer und interner Wärmequellen eine besonders wichtige Rolle spielt. Das gilt auch für die dynamischen Eigenschaften der Werkzeugmaschinen und deren Auswirkungen auf den Prozess. Dies ist bei der Simulation von Maschinenschwingungen zu berücksichtigen.
 
Facing the rising number of exported machine tools supplied by German manufacturers, the influence of the ambient temperature on process results becomes more variant, less predictable and moderate, and thus a constructive task and scientific matter. While the thermal influence on the process accuracy is extensively investigated, this work takes a closer look on the achievable process stability at different ambient temperatures, using modern measurement and simulation techniques.

INTRODUCTION: Data are emerging showing the adverse consequences on mental health of the general public due to the COVID-19 pandemic. Little is known about the needs of veterans with pre-existing mental health difficulties during the COVID-19 pandemic. METHODS: Data were collected through a cross-sectional online survey from a randomly selected sample (n=1092) of military veterans who have sought help for mental health difficulties from a veteran-specific UK-based charity. The response rate was 25.2% (n=275). Participants were asked to complete a range of standardised mental health outcomes (post-traumatic stress disorder (PTSD): Post-traumatic Stress Disorder Checklist, common mental health difficulties (CMDs): 12-Item General Health Questionnaire, difficulties with anger: 5-Item Dimensions of Anger Reactions—Revised and alcohol misuse: Alcohol Use Disorders Identification Test) and endorse a list of potential stressors related to changes to daily life resulting from COVID-19. Regression analyses were fitted to explore predictors of mental health severity. RESULTS: It was observed that symptoms of common mental disorder and PTSD (69.3% and 65.0%, respectively) were the most commonly reported to have been exacerbated by the pandemic. Lack of social support and reporting increasing numbers of stressors related to COVID-19 were consistently associated with increasing severity of a range of mental health difficulties. CONCLUSIONS: Our findings suggest veterans who had pre-existing mental health difficulties prior to the outbreak of COVID-19 may be at increased risk of experiencing CMDs as a result of the pandemic. Intervening to improve levels of social support and offering practical guidance to better manage any additional stressors relating to the pandemic may provide strategies to help reduce the burden of mental health symptoms.

There is a growing interest for marine flooding related to recent catastrophic events and their unintended consequences in terms of casualties and damages, and to the increasing population and issues along the coasts in a context of changing climate. Consequently, the knowledge on marine flooding has progressed significantly for the last years and this review, focused on storm-induced marine submersions, responds to the need for a synthesis. Three main components are presented in the review: (1) a state-of-the-art on marine submersions from the viewpoint of several scientific disciplines; (2) a selection of examples demonstrating the added value of interdisciplinary approaches to improve our knowledge of marine submersions; (3) a selection of examples showing how the management of future crises or the planning efforts to adapt to marine submersions can be supported by new results or techniques from the research community. From a disciplinary perspective, recent progress were achieved with respect to physical processes, numerical modeling, the knowledge of past marine floods and vulnerability assessment. At a global scale, the most vulnerable coastal areas to marine flooding with high population density are deltas and estuaries. Recent and well-documented floods allow analyzing the vulnerability parameters of different coastal zones. While storm surges can nowadays be reproduced accurately, the modeling of coastal flooding is more challenging, particularly when barrier breaches and wave overtopping have to be accounted for. The chronology of past marine floods can be reconstructed combining historical archives and sediment records. Sediment records of past marine floods localized in back barrier depressions are more adequate to reconstruct past flooding chronology. For the two last centuries, quantitative and descriptive historical data can be used to characterize past marine floods. Beyond providing a chronology of events, sediment records combined with geochronology, statistic analysis and climatology, can be used to reconstruct millennial-scale climate variability and enable a better understanding of the possible regional and local long-term trends in storm activity. Sediment records can also reveal forgotten flooding of exceptional intensity, much more intense than those of the last few decades. Sedimentological and historical archives, combined with highresolution topographic data or numerical hindcast of storms can provide quantitative information and explanations for marine flooding processes. From these approaches, extreme past sea levels height can be determined and are very useful to complete time series provided by the instrumental measurements on shorter time scales. In particular, historical data can improve the determination of the return periods associated with extreme water levels, which are often inaccurate when computed based on instrumental data, due to the presence of gaps and too short time-series. Longterm numerical hindcast of tides and surges can also be used to provide the required time series for statistical analysis. Worst-case scenarios, used to define coastal management plans and strategies, can be obtained from realistic atmospheric settings with different tidal ranges and by shifting the trajectory of storms. Management of future crises and planning efforts to adapt to marine submersions are optimized by predictions of water levels from hydrodynamic models. Such predictions combined with in situ measurements and analysis of human stakes can be used to define a vulnerability index. Then, the efficiency of adaptation measures can be evaluated with respect to the number of lives that could be potentially saved. Numerical experiments also showed that the realignment of coastal defenses could result in water level reduction up to 1 m in the case where large marshes are flooded. Such managed realignment of coastal defenses may constitute a promising adaptation to storm-induced flooding and future sea level rise. From a legal perspective, only a few texts pay specific attention to the risk of marine flooding whether nationally or globally. Recent catastrophic events and their unintended consequences in terms of death and damages have triggered political decisions, like in USA after hurricane Katrina, and in France after catastrophic floods that occurred in 2010. ; 151-184pp ; Volume 165 ; DHA/NEC ; Earth-Science Reviews
