Turkish Journal of Emergency Medicine , 2009,
Abstract: Violence is one of the serious problems that should be taken into consideration in emergency service. Violence may be the symptoms of a phsychiatric disorder generally, but it may also be seen in many organic disorders. Although it is an important issue in emergency setting, there is no any standard treatment guideline for its management. However, many pharmacological and non-pharmacological treatment approaches have been reported in the literature. The aim of this article is to review the researches about the management of violence in emergency service.

W. Hufenbach,M. Gude,N. Modler,C. Kirvel
Journal of Achievements in Materials and Manufacturing Engineering , 2007,
Abstract: Purpose: Piezoceramic actuators in lightweight structures enable a purposeful manipulation of the dynamic and vibroacoustic structural behaviour. Above it, further studies focus on the application of thin and flexible piezoceramic modules as power sources in morphing structures aiming at a shape adaptation.Design/methodology/approach: A specific example of novel morphing structures is introduced, which rely on multistable deformation phenomena of fibre-reinforced composites with an unsymmetric lay-up. For the large-scale capable utilisation of such active struc tural parts made of fibre-reinforced thermoplastic composites, novel piezoceramic modules, which are specifically tailored to the structural material, and required manufacturing methods are developed.Findings: The piezoceramic modules with the highly regarded compatibility to ther moplastic composites permit their substantially coherent and homogeneous integration in the fibre composite structure without intricate adhesive assembly effort. Furthermore, thermally induced residual compressive stresses during the manufacturing process serve for pur posefully prestressing the piezoceramic components to reduce the module’s sensitivity to tensile loading.Research limitations/implications: For the manufacture of those novel piezoceramic modules, a continuously operating fabrication method has been developed. By the process-related integration of a hot press, residual compression stresses are thermally induced into the modules that considerably contribute to the decrease of the piezoceramic module’s sensitivity to tension.Originality/value: The successful development of the novel TPM offers a significant advancement in the efficieny within the large scale production of novel intelligent lightweight structures.

Open Access Emergency Medicine , 2011,
Abstract: Yves Chaput1, Lucie Beaulieu2, Michel Paradis3, Edith Labonté41Department of Psychiatry, McGill University, Montreal (presently in private practice); 2Department of Psychiatry, Haut Richelieu Hospital, Saint-Jean-sur-Richelieu, Quebec; 3Department of Psychiatry, University of Montreal, Montreal; 4Department of Psychiatry, Laval University, Quebec, CanadaIntroduction: Studies of aggressive behaviors in a nonforensic mental health setting have focused primarily on the inpatient ward and, on event prediction, using behavior-based clinical rating scales. Few studies have specifically targeted aggressive behaviors in the psychiatric emergency service or determined whether assessing the demographic and clinical characteristics of such patients might prove useful for their more rapid identification.Methods: We used a prospectively acquired database of over 20,900 visits to four services in the province of Quebec, Canada, over a two-year period from September 2002 onwards. A maximum of 72 variables could be acquired per visit. Visits with aggression (any verbally or physically intimidating behavior), both present and past, were tagged. Binary logistic regressions and cross-tabulations were used to determine whether the profile of a variable differed in visits with aggression from those without aggression.Results: About 7% of visits were marked by current aggression (verbal 49%, physical 12%, verbal and physical 39%). Including visits with a “past only” history of aggression increased this number to 20%. Variables associated with aggression were gender (male), marital status (single/separated), education (high school or less), employment (none), judicial history (any type), substance abuse (prior or active), medication compliance (poor), type of arrival to psychiatric emergency services (involuntary, police, judiciary, landlord), reason for referral (behavioral dyscontrol), diagnosis (less frequent in anxiety disorders), and outcome (more frequently placed under observation or admitted).Conclusion: Our results suggest that many state-independent variables are associated with aggressive behaviors in the psychiatric emergency service. Although their sum may not add up to a specific patient profile, they can nevertheless be useful in service planning, being easily integrated alongside state-dependent rating scales in a triage and/or observation instrument for daily use in the psychiatric emergency service.Keywords: psychiatric emergency service, aggressive behaviors, epidemiology

Architecting Service Based Sensor Networks for the Intelligent Assimilation  [PDF]

Chinese Journal of Engineering , 2014, DOI: 10.1155/2014/701829
Abstract: The aim of this paper is to propose an architectural model for assimilating distributed sensor networks through cloud paradigm. This strategy can be applied to monitor and control the physical parameters such as temperature, pressure, and level. It is proposed to consider the use of service oriented architecture to program and deploy the sensed parameters. The service oriented architecture for sensor network has been implemented in such a way that, for every specific requirement of the monitor center, the assimilation agent invokes the services of the sensors through a registry and the specific changes in the sensed parameters are also notified as auditable event using push interaction pattern of SOA. The assimilation agent serves as an intelligent component by providing authentication services. This SOA is extended to integrate different types of sensor networks through cloud environment. Hence several sensors can be networked together to monitor different process parameters and they have been assimilated with Internet by registering them as services, hence a complete distributed assimilation environment is exploited. 1. Introduction The industrial process parameters such as temperature, pressure, and level, are time critical and they have been traditionally monitored at the control centers. The physical parameters measured by analog or digital instruments are converted into electrical parameters such as voltage and/or current, so that it is easier to transmit them to a distant control center. The above methods of monitoring, analysis, and control are possible only within the industrial coverage area. Recent advances in microsensor technology have led to the large-scale deployment of low cost and low power sensing devices to sense the process parameters with computational and wireless communication capabilities. The heterogeneous sensors to sense the different process parameters sensors to sense the different process parameters are networked together to form a distributed sensor network. For such applications, sensor networks could not operate as stand-alone networks. There must be an effective way for user to gain access to the data produced by the sensor networks. The integration of sensor networks with Internet is one of the open research issues in wireless sensor networks. At the same time, it is envisioned that sensor networks are to be pervasive and ubiquitous. It makes a lot of sense to integrate sensor networks with Internet [1]. It is not possible to give an IP address to every sensor node for their large numbers, thereby making it impossible
Intelligent Emergency Stop Algorithm for a Manipulator Using a New Regression Method  [PDF]
Minkyu Cheon,Jeisung Lee,Wonju Lee,Chang-Ho Hyun,Mignon Park
Sensors , 2012, DOI: 10.3390/s120607451
Abstract: In working environments with large manipulators, accidental collisions can cause severe personal injuries and can seriously damage manipulators, necessitating the development of an emergency stop algorithm to prevent such occurrences. In this paper, we propose an emergency stop system for the efficient and safe operation of a manipulator by applying an intelligent emergency stop algorithm. Our proposed intelligent algorithm considers the direction of motion of the manipulator. In addition, using a new regression method, the algorithm includes a decision step that determines whether a detected object is a collision-causing obstacle or a part of the manipulator. We apply our emergency stop system to a two-link manipulator and assess the performance of our intelligent emergency stop algorithm as compared with other models.
