6519 Background: Two years after zoledronate, received FDA approval, four dental professionals treated 107 cases of osteonecrosis of the jaw (ONJ). We review the timeline and source for initial recognition of ONJ and the comprehensiveness of dissemination of information on this adverse drug event. Methods: Data sources included primary case series from dental professionals; published case reports, clinical trials, and cases reported to the manufacturers or the FDA. Exposure adjusted incidence rates estimates were derived from manufacturer sponsored and investigator initiated review of claims data from large cancer centers. Safety notifications were disseminated by the manufacturers, regulatory authorities, and academic investigators. Results: Between 2001 and 2003, 107 patients with ONJ received care from dental professionals. In late 2003, and 2004 peer-reviewed case series were published. By 2006, safety databases maintained by the FDA, the manufacturer, and the RADAR project included information on 2,270, 1,178, and 368 cases of ONJ, respectively. In 2004 and 2005, incidence estimates of 0.8 and 22 ONJ cases per 1,000 person-years of intravenous bisphosphonate therapy were reported by the manufacturer and academic investigators. From 2003 to 2006, safety information from manufacturers, national regulatory authorities, case series, and clinical guidelines were disseminated. Conclusions: Recognition and reporting of ONJ occurred two years after FDA approval of zoledronate, dissemination of safety information occurred in the third year, and publications were disseminated from year three to year five. The life-cycle for identification and information dissemination for this serious adverse drug reaction was short and comprehensive. [Table: see text] [Table: see text]

The safety information dissemination plays a vital role in the VANET communication. It is a technique of transmitting the information at scheduled intervals or during road hazards by detecting the events using onboard system and interfaces. Information is shared between vehicles and road side units which are further used to predict vehicle collisions, road line crossings, environmental warnings, traffic data and road hazards. Interestingly the risk of lateral collisions and dense traffic for vehicles can be avoided by accomplishing fast data dissemination i.e. warning alerts by event detection. Vehicular technology which supports the safe mode of transportation is growing faster due to the deployment of new automated technology in the intelligent transportation system (ITS). The different scenarios used in vehicular communication are Vehicle to Vehicle (V-V), Vehicle to Infrastructure (V-I) and Vehicle to Internet. Some of the important characteristics of vehicular communications are the mobility, frequent changes in topology, varying transmission power of antennas, intermittent connectivity. ITS providing the solutions for most critical transportation issues and inspiring the researchers for the betterment of road safety. In this paper, we propose a multi agent based safety information dissemination scheme for vehicle to vehicle communication. The proposed algorithm performs the safety information dissemination with help of intelligent agents by optimizing the channel access techniques, message encoding and selection of intermediate nodes. Here the communication between source and destination is achieved with fever number of intermediate links by selecting the nodes in the special zone. Short interval codes which represent safety information are effectively transmitted in the intermittent nature of wireless connectivity. This proposed work describes the details of algorithm with associated network environment, multi agent functions and dissemination mechanism to illustrate the improvement in end to end delay, PDR, energy constraints etc. This method reduces the problem of broadcast storm by delivering the information to intended node. Simulation of the proposed work gives the improved results on PDR, latency and connection overhead.

Any systems can be expressed by and connected with information. For the safety education system, doing so is essentially a process of safety information dissemination and cognition. Therefore, information is the core of the safety education system. At present, the key factors affecting the effectiveness of safety education are safety demand analysis information, the dissemination and cognitive processes of safety information and information feedback. Research on the construction of a framework model for safety education under the guidance of information flow clears and classifies information-related elements of the safety education process. Therefore, it is conducive to the construction of a safety education system to improve its management level and, through the rational use of information technology, to improve the conversion rate of safety information into safety behaviour. Based on a systematic review and comparison of the existing research perspectives on safety education and information-flow-based safety education (IFSE), this paper analyses the reasons why we need a new perspective on safety education. We introduce information flow into the safety education framework model. The fundamental and expanding elements of safety education propagation are examined and deduced based on information theory. Combined with the connotations of safety education and information flow, this paper analyses the implementation steps of IFSE and applies them to the safety education of new employees in metal and nonmetal mines. In the micro-design, virtual reality technology is used to integrate safety education content and information technology. A new perspective on safety education is created; then, the framework model of IFSE, its implementation steps and models of the processing and utilization processes of safety education are constructed. IFSE is a new perspective for realizing safety education in practice, and the framework model of IFSE provides rigorous theoretical knowledge. Of course, to improve IFSE in practice, more scientific and detailed evaluation methods need to be introduced. This paper is helpful for guiding the safety education theory research from “trivializes situated” to “systematic” and for guiding the design, implementation, assessment and optimization of the safety education practice.

Time Dissemination

Many safety applications needed safety warning information to be disseminated to all vehicles in an area quickly. A path prediction model was built from the fused evidences by evidence theory, in which the basic probability assignment function of the local load and the old path load could be achieved using fuzzy set. And the loads became the evidences of the dissemination path prediction respectively. The prediction result with the maximal confidence was regarded as the quasi-real-time dissemination path load. Simulations show that the average end-to-end delay of safety information under heavy load with path prediction is less than the half of the delay without path prediction. However, the average packets loss rate of two schemes is almost the same.

This research investigated the direct and indirect effects of the characteristics of motor vehicle drivers in Nebraska, including their socioeconomic characteristics, safe driving knowledge, and attitudes to inattentive driving at highway–rail grade crossings (HRGCs). A random statewide mail survey of drivers aged 19 years or older provided the data analyzed in this research. The use of a structural equation model (SEM) enabled identification of direct and indirect effects among the variables. Conclusions were that drivers’ attitudes toward safety issues at HRGCs had both direct and indirect effects on drivers’ inattentive behavior. Drivers’ intent to violate or obey driving regulations indirectly influenced driver inattention. Their overall knowledge of safely negotiating HRGCs did not directly affect inattentive driving, but it indirectly affected inattentive driving through interference with drivers’ intent to violate or obey regulations. Drivers’ perceptions of delay, safety, clarity, and reliability indirectly affected their inattentive behavior. Variables associated with fewer instances of inattentive driving included: positive attitudes toward safety issues at HRGCs; lower intent to violate (or greater intent to obey) driving rules at HRGCs; less frequent use of HRGCs; higher perceptions of the safety, reliability, and so forth of local HRGCs; older drivers (≥60); better knowledge of safely negotiating HRGCs; lower educational levels; male drivers; lower income households (<US$30 k per year); and longer residency in the current city. Safety information dissemination, high household income (>US$100 k per year), and younger drivers had direct effects on drivers’ safe driving knowledge and could lead to higher overall knowledge levels of safely negotiating HRGCs.
