The result showed that the Smart Delineator was able to identify the location of occurrence and affecting driving according pattern, either adhering to recommended speed or reducing speed according to the pre-defined hazard level.

Teleconsultation in pre-hospital emergency medical services: Real-time telemedical support in a prospective controlled simulation study

BackgroundTeleconsultation from the scene of an emergency to an experienced physician including real-time transmission of monitoring, audio and visual information seems to be feasible.In preparation for bringing such a system into practice within the research project “Med-on-@ix”, a simulation study has been conducted to investigate whether telemedical assistance (TMA) in Emergency Medical Services (EMS) has an impact on compatibility to guidelines and timing. Material and methodsIn a controlled simulation study 29 EMS teams (one EMS physician, two paramedics) ran through standardized scenarios (STEMI: ST-elevation myocardial infarction; MT: major trauma) on high-fidelity patient simulators with defined complications (treatable clearly following guidelines). Team assignments were randomized and each team had to complete one scenario with and another without TMA. Analysis was based on videotaped scenarios using pre-defined scoring items and measured time intervals for each scenario. ResultsAdherence to treatment algorithms improved using TMA. STEMI: cathlab informed (9/14 vs. 15/15; p=0.0169); allergies checked prior to acetylsalicylic acid (5/14 vs. 13/15; p=0.0078); analgosedation prior to cardioversion (10/14 vs. 15/15; p=0.0421); synchronized shock (6/14 vs. 14/15; p=0.0052). MT: adequate medication for intubation (3/15 vs. 10/14; p=0.0092); mean time to inform trauma centre 547 vs. 189s (p=0.0001). No significant impairment of performance was detected in TMA groups. ConclusionsIn simulated setting TMA was able to improve treatment and safety without decline in timing. Nevertheless, further research is necessary to optimize the system for medical, organizational and technical reasons prior to the evaluation of this system in routine EMS.

Some problems of RSC are analyzed in this paper, and then the SRSC system network topology is proposed. Furthermore, the technical integrated architecture and related key technologies are discussed.

Mobility Management for Seamless Information Flow in a Heterogeneous Networks

Problem statement: In the heterogeneous networks, generally the entire networks operating on the Radio Frequencies under wireless mode available for communication are brought under a single head based on their common operating procedures and functions. As a common mode the basic functions of the networks are requesting, tracing, sending, acknowledging, authenticating, authorizing, receiving, updating, forwarding, controlling, registering, managing. As the radio frequency is considered the signal strength, maximum coverage, power level are taken as the major factor. Approach: Todays cellular network has a wide coverage area and also a good signal strength and as the WiMax is considered the data transmission rate and the volume of information communicated is high. As we consider the Adhoc Network the path tracing and the nearby node identification is faster and there is no need for a standard architecture. As the major of the different networks are combined with certain QoS without disturbing the existing infrastructure a fast seamless flow of voluminous information in real time application can be achieved. As the data transmission is considered the major part is affected based on the initiation & delay such as authentication delay, handover delay, session initiation, activation which is being carried out only after the control had reached the service point. Results: In the proposed study the transmission of information is purely controlled by categorizing the type of information that is being transmitted such as the information ready for transmission is online or offline. Coming to on line either voice communication, Multimedia communication or real-time information transmission. Considering the offline the information is stored file or images. Among the above one the real time video transmission is considered as the major application because delay cannot be permitted and one more thing the mobility should be managed without any break in the transmission path. The rapidly growing demand for “anywhere, anytime” high-speed access to IP-based services is becoming one of the major challenges for mobile networks. Conclusion: As the demand for mobility increases, mobile terminals need to roam freely across heterogeneous networks, posing the challenge of network integration into an All-IP ubiquitous access platform.

Precision livestock production: tools and concepts

Precision livestock production (PLP) is the augmentation of precision agriculture (PA) concepts to include all components of agroecosystems, particularly animals and plant-animal interactions. Soil, plants and soil-plant interactions are the subjects of PA or site-specific farming, where the main principle is to exploit natural spatial heterogeneity to increase efficiency and reduce environmental impacts. For the most part, PA has been studied and developed for intensive cropping systems with little attention devoted to pastoral and agropastoral systems. PLP focuses on the animal component and exploits heterogeneity in space and among individual animals towards more efficient and environmentally friendly production. Within PLP, precision grazing consists of the integration of information and communication technologies with knowledge about animal behavior and physiology to improve production of meat, milk and wool in grazing conditions. Two main goals are to minimize overgrazing of sensitive areas and to maximize the quality of the product through enhanced traceability. An integrated precision grazing system is outlined with its components: sensors of animal position, behavior and physiological status, real-time transmission of information to a decision support system, and feed-back through a series of actuators. Control of animal movement and diets is based on knowledge about species specific responses to various stimuli within the paradigms of flavor aversions and operant conditioning. Recent advances in the technologies and instrumentation available are reviewed briefly and linked to current livestock identification systems. The precision grazing vision is presented in full and the areas that need further research and development are discussed.

What Do Spanish Physicians Believe and Expect about Telemedicine? Results of a Delphi-Based Survey

The aim of this Delphi-based study was to evaluate the intention of Spanish physicians to accept and use telemedicine as a future useful tool in daily practice. An online Delphi questionnaire was answered by 985 physicians (966 in the second round), representatives from rural and urban areas of the entire country (generalists, internists, cardiologists, endocrinologists, and nephrologists). The participants were 65% males, with a mean age of 46.7 years old and 20.3 years in the profession, mostly coming from primary care centers (91.8%) of urban Spanish areas (72.8%). Some responders (56.4%) reported lack of Internet use at work and 80.2% never participated in a telemedicine project, but 80.9% said they would be interested in participating in the future. As for the benefits of telemedicine, the specialties perceived as the most benefited were cardiology, followed by general medicine, pediatrics, and emergency services. The main reported difficulty for telemedicine implementation was the opinion that patients prefer the physical contact with physicians (77.8% of responders). Interviewed participants expressed strong interest in future telemedicine projects related to online training, distance control of chronic diseases, online communication among specialists, and real-time transmission of images and information. Most Spanish physicians have not implemented telemedicine in clinical practice, but they would be interested in future applications such as on-line training or disease control, although they still prefer physical patient contact.

A Randomized Controlled Trial of the Effect of Real-Time Telemedicine Support on Glycemic Control in Young Adults With Type 1 Diabetes (ISRCTN 46889446)

To determine whether a system of telemedicine support can improve glycemic control in type 1 diabetes. A 9-month randomized trial compared glucose self-monitoring real-time result transmission and feedback of results for the previous 24 h in the control group with real-time graphical phone-based feedback for the previous 2 weeks together with nurse-initiated support using a web-based graphical analysis of glucose self-monitoring results in the intervention group. All patients aged 18-30 years with HbA(1c) (A1C) levels of 8-11% were eligible for inclusion. A total of 93 patients (55 men) with mean diabetes duration (means +/- SD) 12.1 +/- 6.7 years were recruited from a young adult clinic. In total, the intervention and control groups transmitted 29,765 and 21,400 results, respectively. The corresponding median blood glucose levels were 8.9 mmol/l (interquartile range 5.4-13.5) and 10.3 mmol/l (6.5-14.4) (P < 0.0001). There was a reduction in A1C in the intervention group after 9 months from 9.2 +/- 1.1 to 8.6 +/- 1.4% (difference 0.6% [95% CI 0.3-1.0]) and a reduction in A1C in the control group from 9.3 +/- 1.5 to 8.9 +/- 1.4% (difference 0.4% [0.03-0.7]). This difference in change in A1C between groups was not statistically significant (0.2% [-0.2 to 0.7, P = 0.3). Real-time telemedicine transmission and feedback of information about blood glucose results with nurse support is feasible and acceptable to patients, but to significantly improve glycemic control, access to real-time decision support for medication dosing and changes in diet and exercise may be required.
