    In this chapter, we look into the role of telecommunication networks and their capability of supporting critical infrastructure systems and applications. The focus is on smart grids as the key driving example, bearing in mind that other such systems do exist, e.g., water management, traffic control......, etc. First, the role of basic communication is examined with a focus on critical infrastructures. We look at heterogenic networks and standards for smart grids, to give some insight into what has been done to ensure inter-operability in this direction. We then go to the physical network, and look...... at the deployment of the physical layout of the communication network and the related costs. This is an important aspect as one option to use existing networks is to deploy dedicated networks. Following this, we look at some generic models that describe reliability for accessing dynamic information. This part...

    International Nuclear Information System (INIS)

    The Office of Civilian Radioactive Waste Management (OCRWM) must, among other things, be equipped to readily produce, file, store, access, retrieve, and transfer a wide variety of technical and institutional data and information. The data and information regularly produced by members of the OCRWM Program supports, and will continue to support, a wide range of program activities. Some of the more important of these information communication-related activities include: supporting the preparation, submittal, and review of a license application to the Nuclear Regulatory Commission (NRC) to authorize the construction of a geologic repository; responding to requests for information from parties affected by and/or interested in the program; and providing evidence of compliance with all relevant Federal, State, local, and Indian Tribe regulations, statutes, and/or treaties. The OCRWM Telecommunications Network Plan (TNP) is intended to identify, as well as to present the current strategy for satisfying, the telecommunications requirements of the civilian radioactive waste management program. The TNP will set forth the plan for integrating OCRWM's information resources among major program sites. Specifically, this plan will introduce a telecommunications network designed to establish communication linkages across the program's Washington, DC; Chicago, Illinois; and Las Vegas, Nevada, sites. The linkages across these and associated sites will comprise Phase I of the proposed OCRWM telecommunications network. The second phase will focus on the modification and expansion of the Phase I network to fully accommodate access to the OCRWM Licensing Support System (LSS). The primary components of the proposed OCRWM telecommunications network include local area networks; extended local area networks; and remote extended (wide) area networks. 10 refs., 6 figs

    2011-01-01

    Full Text Available A topological analysis of the structure of telecommunications networks is a very interesting topic in the network research, but also a key issue in their design and planning. Satisfying multiple criteria in terms of locations of switching nodes as well as their connectivity with respect to the requests for capacity, transmission speed, reliability, availability and cost are the main research objectives. There are three ways of presenting the topology of telecommunications networks: table, matrix or graph method. The table method is suitable for a network of a relatively small number of nodes in relation to the number of links. The matrix method involves the formation of a connection matrix in which its columns present source traffic nodes and its rows are the switching systems that belong to the destination. The method of the topology graph means that the network nodes are connected via directional or unidirectional links. We can thus easily analyze the structural parameters of telecommunications networks. This paper presents the mathematical analysis of the star-, ring-, fully connected loop- and grid (matrix-shaped topology as well as the topology based on the shortest path tree. For each of these topologies, the expressions for determining the number of branches, the middle level of reliability, the medium length and the average length of the link are given in tables. For the fully connected loop network with five nodes the values of all topological parameters are calculated. Based on the topological parameters, the relationships that represent integral and distributed indicators of reliability are given in this work as well as the values of the particular network. The main objectives of the topology optimization of telecommunications networks are: achieving the minimum complexity, maximum capacity, the shortest path message transfer, the maximum speed of communication and maximum economy. The performance of telecommunications networks is

    Full Text Available In many application, the network designer may to know to senthesise a reliable telecommunication network. Assume that a network, denoted Gm,e has the number of nodes n and the number of edges e, and the operational probability of each edge is known. The system reliability of the network is defined to be the reliability that every pair of nodes can communicate with each other. A network synthesis problem considered in this paper is to find a network G*n,e, that maximises system reliability over the class of all networks for the classes of networks Gn,n-1, Gn,m and Gn,n+1 respectively. In addition an upper bound of maximum reliability for the networks with n-node and e-edge (e>n+2 is derived in terms of node. Computational experiments for the reliability upper are also presented. the results show, that the proposed reliability upper bound is effective.

  17. Reputation-based Telecommunication Network Selection

    Seigneur, Jean-Marc

    2010-01-01

    Nowadays, mobile users can switch between different available networks, for example, nearby WiFi networks or their standard mobile operator network. Soon it will be extended to other operators. However, unless telecommunication operators can directly benefit from allowing a user to switch to another operator, operators have an incentive to keep their network quality of service confidential to avoid that their users decide to switch to another network. In contrast, in a user-centric way, the users should be allowed to share their observations regarding the networks that they have used. In this paper, we present our work in progress towards attack-resistant sharing of quality of service information and network provider reputation among mobile users.

    The U.S. Army Medical Command, lead by the Brooke Army Medical Center, has embarked on a futuristic project that will revolutionize the practice of teleradiology in the DoD. The U.S. Army Virtual Radiology Environment (USAVRE) is a CONUS- based network that connects all the Army's major medical centers and Regional Medical Commands (RMC). The purpose of the USAVRE is to improve the quality, access, and cost of radiology services in the Army via the use of state-of-the-art medical imaging, computer, and networking technologies. The USAVRE contains multimedia-viewing workstations for static and dynamic modality cases. The storage and archiving systems are based on a distributed computing environment using Common Object Request Broker Architecture (CORBA) middleware protocols. Collaborations between archive centers and viewing workstations are managed by CORBA functions and multimedia object streams. The underlying telecommunications network is an ATM-based backbone network that connects to the RMC regional networks and PACS networks at medical centers and RMC clinics. The U.S. Army Information Systems Engineering Command (USAISEC) at Ft. Huachuca, AZ is responsible for the ATM backbone network to the RMC sites. This project is a collaborative effort between Army, university, and industry centers with expertise in teleradiology and Global PACS applications. This paper describes the telecommunications backbone network architecture for the Cable Bundling Initiative (CBI) being deployed by the Technology Integration Center. The U.S. Army U.S. Army Information Systems Engineering Command (USAISEC) at Ft. Huachuca, AZ has begun deployment of a 45 Mbps backbone network called the Cable Bundling Initiative (CBI).

  5. A Functional Complexity Framework for the Analysis of Telecommunication Networks

    CERN Document Server

    Dzaferagic, Merim; Macaluso, Irene; Marchetti, Nicola

    2016-01-01

    The rapid evolution of network services demands new paradigms for studying and designing networks. In order to understand the underlying mechanisms that provide network functions, we propose a framework which enables the functional analysis of telecommunication networks. This framework allows us to isolate and analyse a network function as a complex system. We propose functional topologies to visualise the relationships between system entities and enable the systematic study of interactions between them. We also define a complexity metric $C_F$ (functional complexity) which quantifies the variety of structural patterns and roles of nodes in the topology. This complexity metric provides a wholly new approach to study the operation of telecommunication networks. We study the relationship between $C_F$ and different graph structures by analysing graph theory metrics in order to recognize complex organisations. $C_F$ is equal to zero for both a full mesh topology and a disconnected topology. We show that complexi...

    Random SALOHA and CSMA protocols that are used to access MAC in ad hoc networks are very small compared to the multiple and spontaneous use of the transmission channel. So they have low immunity to the problems of packet collisions. Indeed, the transmission time is the critical factor in the operation of such networks. The simulations demonstrate the positive impact of erasure codes on the throughput of the transmission in ad hoc networks. However, the network still suffers from the intermittency and volatility of its efficiency throughout its operation, and it switches quickly to the satura

  8. Improvement in Energy Optimization in Telecommunication Network Service

    Kadiri Kamoru. O

    2014-09-01

    Full Text Available Energy-efficient operation is an important issue today in telecommunication networks and in the near future. Due to the fact that the energy consumption rises with the increased in demand for capacity and network speed, this arises a strategies for a sustainable network management. It is a well-known fact that traffic demands vary significantly over periods and areas, most notably in day/night- and in weekly cycles. This provides the main potential for energy-saving strategies. Here is the question of how much power is necessary to operate a network during peak or low-traffic times? How much energy is spent in the core and in metro regions of the network and how big are the savings in low-demand scenarios if we always assume the system power-minimum in these situations? The study respects realistic side constraints, such as protection requirements and routing schemes, and takes the special structure of an extensive nation-wide optical network, including backbone and regional sections, into account. This paper presents a comprehensive summary of recent work addressing energy efficient and low-power design within all layers of the telecommunication network

    Full Text Available This paper presents a practical proposition for the application of the Linear Programming quantitative method in order to assist planning and control of customer circuit delivery activities in telecommunications companies working with the corporative market. Based upon data provided for by a telecom company operating in Brazil, the Linear Programming method was employed for one of the classical problems of determining the optimum mix of production quantities for a set of five products of that company: Private Telephone Network, Internet Network, Intranet Network, Low Speed Data Network, and High Speed Data Network, in face of several limitations of the productive resources, seeking to maximize the company’s monthly revenue. By fitting the production data available into a primary model, observation was made as to what number of monthly activations for each product would be mostly optimized in order to achieve maximum revenues in the company. The final delivery of a complete network was not observed but the delivery of the circuits that make it up, and this was a limiting factor for the study herein, which, however, brings an innovative proposition for the planning of private telecommunications network provisioning.

    International Nuclear Information System (INIS)

    The use of photovoltaic systems as a stand-alone power supply in Libyan telecommunication networks has been in use since 1980. It was proved that PV generators are reliable and cost effective in this type of applications in comparison with diesel generators. In Libya about 100 photovoltaic systems were put into work to supply electricity for repeater stations instead of diesel generators, these PV systems proved to be reliable, very low or no communication stops, and and more economical in comparison with stations running by diesel generators, a wide knowledge of experience has been built of using photovoltaic systems in this applications. This paper is focusing on the role of stand-alone PV systems in communication networks of Libya, as a stand alone power source for telecommunication repeater stations. We will evaluate some of these systems after ten years of work, discuss the past experience, their reliability, and running cost, Stand-alone systems can be used in telecommunication networks, and in general the experienced advantages of using PV solar generators can be summarized as low running cost, high reliability, fewer services visits,, low maintenance cost, less number of thefts, no communication stops.(Author)

    2009-01-01

    The mode of telecommunication network management is changing from "network oriented" to "subscriber oriented". Aimed at enhancing subscribers'feeling, proactive performance monitoring (PPM) can enable a fast fault correction by detecting anomalies designating performance degradation. In this paper, a novel anomaly detection approach is the proposed taking advantage of time series prediction and the associated confidence interval based on multiplicative autoregressive integrated moving average (ARIMA). Furthermore, under the assumption that the training residual is a white noise process following a normal distribution, the associated confidence interval of prediction can be figured out under any given confidence degree 1-α by constructing random variables satisfying t distribution. Experimental results verify the method's effectiveness.

  13. US computer research networks: Domestic and international telecommunications capacity requirements

    Kratochvil, D.; Sood, D.

    1990-01-01

    The future telecommunications capacity and connectivity requirements of the United States (US) research and development (R&D) community raise two concerns. First, would there be adequate privately-owned communications capacity to meet the ever-increasing requirements of the US R&D community for domestic and international connectivity? Second, is the method of piecemeal implementation of communications facilities by individual researchers cost effective when viewed from an integrated perspective? To address the capacity issue, Contel recently completed a study for NASA identifying the current domestic R&D telecommunications capacity and connectivity requirements, and projecting the same to the years 1991, 1996, 2000, and 2010. The work reported here extends the scope of an earlier study by factoring in the impact of international connectivity requirements on capacity and connectivity forecasts. Most researchers in foreign countries, as is the case with US researchers, rely on regional, national or continent-wide networks to collaborate with each other, and their US counterparts. The US researchers' international connectivity requirements, therefore, stem from the need to link the US domestic research networks to foreign research networks. The number of links and, more importantly, the speeds of links are invariably determined by the characteristics of the networks being linked. The major thrust of this study, therefore, was to identify and characterize the foreign research networks, to quantify the current status of their connectivity to the US networks, and to project growth in the connectivity requirements to years 1991, 1996, 2000, and 2010 so that a composite picture of the US research networks in the same years could be forecasted. The current (1990) US integrated research network, and its connectivity to foreign research networks is shown. As an example of projections, the same for the year 2010 is shown.

    Full Text Available Technological developments in recent years have transformed the telecommunications environments in more complexes, distributed, heterogeneous and dynamic systems difficult to manage. Traditional management approaches show their limits to these new architectures. One possible approach to manage these environments is to develop novels models and open management systems. In this work, we proposed a new generic model with six layers for open systems development. We then proposed a flexible management system based on an open paradigm to the integrated management of next generation networks and services. We first studied the open source systems management to present out their strengths and weaknesses. The generic layered model that we propose allows integrating new management functions. And finally we have developed and implemented a system for remote configuration management of network devices

    2011-10-11

    Disclosed is a method and apparatus for conserving power in a telecommunications network during emergency situations. A permissible number list of emergency and/or priority numbers is stored in the telecommunications network. In the event of an emergency or power failure, input digits of a call to the telecommunications network are compared to the permissible number list. The call is processed in the telecommunications network and routed to its destination if the input digits match an entry in the permissible number list. The call is dropped without any further processing if the input digits do not match an entry in the permissible number list. Thus, power can be conserved in emergency situations by only allowing emergency and/or priority calls.

    Bashar, Abul; Parr, Gerard; McClean, Sally; Scotney, Bryan; Nauck, Detlef

    The ever-evolving nature of telecommunication networks has put enormous pressure on contemporary Network Management Systems (NMSs) to come up with improved functionalities for efficient monitoring, control and management. In such a context, the rapid deployments of Next Generation Networks (NGN) and their management requires intelligent, autonomic and resilient mechanisms to guarantee Quality of Service (QoS) to the end users and at the same time to maximize revenue for the service/network providers. We present a framework for evaluating a Bayesian Networks (BN) based Decision Support System (DSS) for assisting and improving the performance of a Simple Network Management Protocol (SNMP) based NMS. More specifically, we describe our methodology through a case study which implements the function of Call Admission Control (CAC) in a multi-class video conferencing service scenario. Simulation results are presented for a proof of concept, followed by a critical analysis of our proposed approach and its application.

    Full Text Available An intelligent network (IN is a service-independent telecommunications network. That is, intelligence is taken outof the switch and placed in computer nodes that are distributed throughout the network. This provides the network operator with the means to develop and control services more efficiently. New capabilities can be rapidly introduced into the network. Once introduced, services are easily customized to meet individual customer's needs. Wireless intelligent network (WIN is a concept being developed by the Telecommunications Industry Association (TIAStandards Committee TR45.2. The charter of this committee is to drive intelligent network (IN capabilities, based on interim standard (IS-41, into wireless networks. IS–41 is a standard currently being embraced by wireless providers because it facilitates roaming. Basing WIN standards on this protocol enables a graceful evolution to anIN without making current network infrastructure obsolete.

    Science.gov (United States)

    Lord, Andrew; Soppera, Andrea; Jacquet, Arnaud

    2016-03-01

    This paper discusses both UK-based and global Internet data bandwidth growth, beginning with historical data for the BT network. We examine the time variations in consumer behaviour and how this is statistically aggregated into larger traffic loads on national core fibre communications networks. The random nature of consumer Internet behaviour, where very few consumers require maximum bandwidth simultaneously, provides the opportunity for a significant statistical gain. The paper looks at predictions for how this growth might continue over the next 10-20 years, giving estimates for the amount of bandwidth that networks should support in the future. The paper then explains how national networks are designed to accommodate these traffic levels, and the various network roles, including access, metro and core, are described. The physical layer network is put into the context of how the packet and service layers are designed and the applications and location of content are also included in an overall network overview. The specific role of content servers in alleviating core network traffic loads is highlighted. The status of the relevant transmission technologies in the access, metro and core is given, showing that these technologies, with adequate research, should be sufficient to provide bandwidth for consumers in the next 10-20 years.

    s of workshop papers are presented. Networked reality refers to the array of technologies and services involved in collecting a representation of reality at one location and using it to reconstruct an artificial representation of that reality at a remote location. The term encompasses transmission of the required information between the sites, and also includes the psychological, cultural, and legal implications of introducing derived communication systems. Networked reality is clearly derived from the emerging virtual reality technology base but is intended to go beyond the latter to include its integration with the required telecommunication technologies. A noteworthy feature of the Networked Reality '94 technical program is the extent of emphasis on social (particularly medical) impacts of the technology.

  19. Achieving QoS for Aeronautical Telecommunication Networks over Differentiated Services

    Science.gov (United States)

    Bai, Haowei; Atiquzzaman, Mohammed; Ivancic, William

    2001-01-01

    Aeronautical Telecommunication Network (ATN) has been developed by the International Civil Aviation Organization to integrate Air-Ground and Ground-Ground data communication for aeronautical applications into a single network serving Air Traffic Control and Aeronautical Operational Communications. To carry time critical information required for aeronautical applications, ATN provides different Quality of Services (QoS) to applications. ATN has therefore, been designed as a standalone network which implies building an expensive separate network for ATN. However, the cost of operating ATN can be reduced if it can be run over a public network such as the Internet. Although the current Internet does not provide QoS, the next generation Internet is expected to provide QoS to applications. The objective of this paper is to investigate the possibility of providing QoS to ATN applications when it is run over the next generation Internet. Differentiated Services (DiffServ), one of the protocols proposed for the next generation Internet, will allow network service providers to offer different QoS to customers. Our results show that it is possible to provide QoS to ATN applications when they run over a DiffServ backbone.

    Full Text Available This paper deals with management system requirements in telecommunications. A TMN (Telecommunication Management Network is necessary to be well designed and constantly upgraded. The  ETOM (Enhanced Telecommunication Operation Map framework, defined by the ITU-T Recommendation M.3050, is used to describe various processes that occur in the network for monitoring and control of military telecommunications systems. Their definition is an essential precondition for introducing management applications that would manage all of the processes in their end-to-end structure. Telecommunication networks are categorized in  accordance withg their functions. A set of relevant network processes important for supervision and management is explained for each described subsystem. This defining represents a prerequisite for the management application configuration which aims to automate management functions and services. eTOM frame and its implementation in telecommunication management networks ETOM is defined as a telecommunication conceptual frame which includes all the processes that exist in a telecommunication network. It does not represent a telecommunication model, but gives a basic frame for all the processes to be included within. It ranges throughout three basic areas: operation processes, planning and development processes and production management. ETOM supports two different process grouping perspectives: horizontal and vertical. The aim of this kind of grouping is to provide the complete overview in all the processes a telecommunication management network should include. Horizontal grouping includes functional processes within the same managed system. Vertical grouping includes all the processes within a TMN. Overlapped horizontal and vertical group constellations enable a connected matrix structure of the eTOM frame. Operational processes within a TMN can be divided into a few categories: user-network interaction, services management and

  4. The universal service in the future of network-type industries: telecommunications, electricity, postal services

    International Nuclear Information System (INIS)

    The notion of universal service emerged in the European regulation of the telecommunications sector, and can be applied to all network-type industries. Public monopolies have been put into question again. The introduction of deregulation and competitiveness were expected to improve the service provided to the end consumer, but this deregulation has been also put into question again for matters of universality and equity. Then the issue of financing of these services emerges. The aim of this research thesis is therefore to identify which funding modes can be optimal, and to identify a general methodology for all network-type industries. In the first part of this research thesis, the author studies the cost of universal service obligations. She explains the general methodology of calculation of this cost, and reports this calculation while taking indirect benefits of the operator into account. In a second part, she studies the modalities of financing thus calculated cost by describing the different possible modalities, their benefits and drawbacks, and by presenting a comparison between these methodologies according to three criteria: those set by the European Commission, welfare, and applicability. For these different topics, the author takes all experiments and recent developments into account. These experiments and developments are noticed in different countries: USA, Australia, UK, Sweden, Netherlands, Germany, Belgium, Italy, France

    Science.gov (United States)

    Staniec, Kamil; Habrych, Marcin

    2016-01-01

    The importance of constructing wide-area sensor networks for holistic environmental state evaluation has been demonstrated. A general structure of such a network has been presented with distinction of three segments: local (based on ZigBee, Ethernet and ModBus techniques), core (base on cellular technologies) and the storage/application. The implementation of these techniques requires knowledge of their technical limitations and electromagnetic compatibility issues. The former refer to ZigBee performance degradation in multi-hop transmission, whereas the latter are associated with the common electromagnetic spectrum sharing with other existing technologies or with undesired radiated emissions generated by the radio modules of the sensor network. In many cases, it is also necessary to provide a measurement station with autonomous energy source, such as solar. As stems from measurements of the energetic efficiency of these sources, one should apply them with care and perform detailed power budget since their real performance may turn out to be far from expected. This, in turn, may negatively affect-in particular-the operation of chemical sensors implemented in the network as they often require additional heating. PMID:27447633

  8. Using heuristic algorithms for capacity leasing and task allocation issues in telecommunication networks under fuzzy quality of service constraints

    Science.gov (United States)

    Huseyin Turan, Hasan; Kasap, Nihat; Savran, Huseyin

    2014-03-01

    Nowadays, every firm uses telecommunication networks in different amounts and ways in order to complete their daily operations. In this article, we investigate an optimisation problem that a firm faces when acquiring network capacity from a market in which there exist several network providers offering different pricing and quality of service (QoS) schemes. The QoS level guaranteed by network providers and the minimum quality level of service, which is needed for accomplishing the operations are denoted as fuzzy numbers in order to handle the non-deterministic nature of the telecommunication network environment. Interestingly, the mathematical formulation of the aforementioned problem leads to the special case of a well-known two-dimensional bin packing problem, which is famous for its computational complexity. We propose two different heuristic solution procedures that have the capability of solving the resulting nonlinear mixed integer programming model with fuzzy constraints. In conclusion, the efficiency of each algorithm is tested in several test instances to demonstrate the applicability of the methodology.

    The introduction of contestability conditions in the market of electricity distribution, following the dominant economic paradigm (Neoclassical or Marginalist) and solidary to the commercialization segment, it doesn't exhibit satisfactory solutions at the present time. This asseveration, of general character, have special incumbency for those countries of Latin America that, from regulatory schemes, try to define a deregulated market for certain kind of user (denominated eligible). A eligible user is characterized by to have demands equal or higher than a preset threshold value of electric power/ energy. In this work, considering the models implemented in the telecommunications networks, the problem of allocation of distribution costs, as the first step toward a contestable offer in the retail energy service, is discussed to establishing access prices in the distribution networks (non contestable markets). The analysis is focalized to definition of two market segments: one regulated and other competitive. Their methodological and instrumentation difficulties, are presented, concluding in the necessity of an alternative paradigm.

    2000-11-01

    Primary care research networks are being publicly funded in the United Kingdom to promote a culture of research and development in primary care. This paper discusses the organisational form of these networks and how their productivity can be evaluated, drawing on evidence from management science. An evaluation of a research network has to take account of the complexity of the organisation, the influence of its local context, and its stage of development. Output measures, such as number of research papers, and process measures, such as number of research meetings, may contribute to an evaluation. However, as networking relies on the development of informal, trust-based relationships, the quality of interactions within a network is of paramount importance for its success. Networks can audit and reflect on their success in promoting such relationships and a more formal qualitative evaluation by an independent observer can document their success to those responsible for funding.

  3. A new Mn-Zn ferrite for high-speed data transmission applications in telecommunication networks

    International Nuclear Information System (INIS)

    In DSL and ISDN telecommunication technologies, advanced modems are used to increase data transmission speed over regular UTP lines. The good operation of these modems requires a low signal distortion of the polycrystalline Mn-Zn ferrites used as transformer core components at low fields. Given that distortion is directly related to the non-linearity of the B-H loop, the purpose of this study was to determine the basic guidelines for the development of Mn-Zn ferrites with a linear B-H behaviour. It appears that retarding the Fe2+-Fe3+ electron exchange with appropriate dopants such as TiO2 leads to the manufacturing of Mn-Zn ferrite materials that exhibit high initial permeability (∼8500), low losses (tan δ/μ-6 at 25 deg. C, 10 kHz, 0.25 mT and tan δ/μ-6 at 25 deg. C, 100 kHz, 0.25 mT) and low hysteresis material constant (-3), that are suitable for DSL and ISDN transformer applications

    Social network is a social structure made of individuals or organizations associated with one or more types of interdependence (friendship, common interests, work, knowledge, prestige, etc.) which are the "nodes" of the network. Networks can be organized to exchange information, knowledge or financial assistance under the various interest groups in universities, workplaces and associations of citizens. Today the most popular and widely used networks are based on application of the Internet as the main ICT. Depending on the method of connection, their field of activity and expertise of those who participate in certain networks, the network can be classified into the following groups: a) Social Networks with personal physical connectivity (the citizens' associations, transplant networks, etc.), b) Global social internet network (Facebook, Twitter, Skype), c) specific health internet social network (forums, Health Care Forums, Healthcare Industry Forum), d) The health community internet network of non professionals (DailyStrength, CaringBridge, CarePages, MyFamilyHealth), e) Scientific social internet network (BiomedExperts, ResearchGate, iMedExchange), f) Social internet network which supported professionals (HealthBoards, Spas and Hope Association of Disabled and diabetic Enurgi), g) Scientific medical internet network databases in the system of scientific and technical information (CC, Pubmed/Medline, Excerpta Medica/EMBASE, ISI Web Knowledge, EBSCO, Index Copernicus, Social Science Index, etc.). The information in the network are exchanged in real time and in a way that has until recently been impossible in real life of people in the community. Networks allow tens of thousands of specific groups of people performing a series of social, professional and educational activities in the place of living and housing, place of work or other locations where individuals are. Network provides access to information related to education, health, nutrition, drugs, procedures

    "The nation which most completely assimilates high performance computing into its economy will very likely emerge as the dominant intellectual, economic, and technological force in the next century", Senator Albert Gore, Jr., May 18, 1989, while introducing Senate Bill 1067, "The National High Performance Computer Technology Act of 1989". A national network designed to link supercomputers, particle accelerators, researchers, educators, government, and industry is beginning to emerge. The degree to which the United States can mobilize the resources inherent within our academic, industrial and government sectors towards the establishment of such a network infrastructure will have direct bearing on the economic and political stature of this country in the next century. This program will have significant impact on all forms of information transfer, and peripheral benefits to all walks of life similar to those experienced from the moon landing program of the 1960's. The key to our success is the involvement of scientists, librarians, network designers, and bureaucrats in the planning stages. Collectively, the resources resident within the United States are awesome; individually, their impact is somewhat more limited. The engineers, technicians, business people, and educators participating in this conference have a vital role to play in the success of the National Research and Education Network (NREN).

  14. A measurement-driven approach to assess power line telecommunication (PLT) network quality of service (QoS) performance parameters

    International Nuclear Information System (INIS)

    Power line telecommunication (PLT) technology offers cheap and fast ways for providing in-home broadband services and local area networking. Its main advantage is due to the possibility of using the pre-existing electrical grid as a communication channel. Nevertheless, technical challenges arise from the difficulty of operating on a hostile medium, not designed for communication purposes, characterized by complex channel modeling and by varying time response. These aspects put practical problems for designers and testers in the assessment of network quality of service performance parameters such as the throughput, the latency, the jitter, and the reliability. The measurement of these parameters has not yet been standardized so that there do not exist reference test set-ups and measurement methodologies (i.e. the type of isolation from the ac main, the observation time and the number of experiments, the measurement uncertainty and so on). Consequently, experiments executed by adopting different methods may lead to incompatible measurement results, thus making it also impossible to have reliable comparisons of different PLT modems. Really, the development of standard procedures is a very difficult task because the scenarios in which the PLT modems can work are very wide and then the application of an exhaustive approach (in which all the parameters influencing the PLT performance should be considered) would be very complex and time consuming, thus making the modem characterization very expensive. In this paper, the authors propose a methodological approach to develop an efficient measurement procedure able to reliably assess the performance of PLT modems (in terms of network quality of service parameters) with a minimum number of experiments. It is based on both creating a reconfigurable grid to which real disturbing loads are connected and implementing an original design of the experiment technique based on the effects of the uncertainty of the measurement results

    Fulfilling the shared care paradigm, health care networks providing open systems' interoperability in health care are needed. Such communicating and co-operating health information systems, dealing with sensitive personal medical information across organisational, regional, national or even international boundaries, require appropriate security solutions. Based on the generic security model, within the European MEDSEC project an open approach for secure EDI like HL7, EDIFACT, XDT or XML has been developed. The consideration includes both securing the message in an unsecure network and the transport of the unprotected information via secure channels (SSL, TLS etc.). Regarding EDI, an open and widely usable security solution has been specified and practically implemented for the examples of secure mailing and secure file transfer (FTP) via wrapping the sensitive information expressed by the corresponding protocols. The results are currently prepared for standardisation. PMID:10724890

    2014-10-01

    Full Text Available An innovative wireless monitoring system for measuring greenhouse climatic parameters was developed to overcome the problems related to wires cabling such as presence of a dense net of wires hampering the cultivation practices, wires subjected to high temperature and relative humidity, rodents that can damage wires. The system exploits battery-powered environmental sensors, such as air temperature and relative humidity sensors, wind speed and direction, and solar radiation sensors, integrated in the contest of an 802.15.4-based wireless sensors network. Besides, a fruit diameter measurement sensor was integrated into the system. This approach guarantees flexibility, ease of deployment and low power consumption. Data collected from the greenhouse are then sent to a remote server via a general packet radio service link. The proposed solution has been implemented in a real environment. The test of the communication system showed that 0.3% of the sent data packed were lost; the climatic parameters measured with the wireless system were compared with data collected by the wired system showing a mean value of the absolute difference equal to 0.6°C for the value of the greenhouse air temperature. The wireless climate monitoring system showed a good reliability, while the sensor node batteries showed a lifetime of 530 days.

    In today's competitive landscape for health care talent, nursing executives and human resource professionals need to assess and evaluate new avenues for recruitment. The strategy of filling positions by means of print advertising is becoming outmoded quickly. As an industry, health care typically lags behind other industries when it relates to technology. This is especially true in implementing any interactive strategies to target hard-to-fill positions. Social networking sites have appeared on the Internet landscape quickly and continue to flourish. Nurse leaders need to capitalize on this phenomenon. PMID:18080628

Time distribution and quality of information directly affect the implementation of the decision making process and criteria for evaluating the effectiveness of the system in which the achievement of the most important role is an integrated telecommunications and computer network (ITCN, dimensioned to the spatial distribution of tactical combat units connecting all the elements in a communications unit. The aim is to establish the design methodology as a way of the ITCN necessary to conduct analysis and extract all the necessary elements for modeling that are mapped to the elements of network infrastructure, and then analyzed from the perspective of telecommunications communication standards and parameters of the layers of the OSI network model. A relevant way to verify the designed model ITCN is the development of a simulation model with which adequate results can be obtained. Conclusions on the compliance with the requirements of tactical combat and tactical communication requirements are drawn on the basis of these results.

    Full Text Available Abstract Background Despite the increase of mobile phone use in the last decade and the growing concern whether mobile telecommunication networks adversely affect health and well-being, only few studies have been published that focussed on children and adolescents. Especially children and adolescents are important in the discussion of adverse health effects because of their possibly higher vulnerability to radio frequency electromagnetic fields. Methods We investigated a possible association between exposure to mobile telecommunication networks and well-being in children and adolescents using personal dosimetry. A population-based sample of 1.498 children and 1.524 adolescents was assembled for the study (response 52%. Participants were randomly selected from the population registries of four Bavarian (South of Germany cities and towns with different population sizes. During a Computer Assisted Personal Interview data on participants' well-being, socio-demographic characteristics and potential confounder were collected. Acute symptoms were assessed three times during the study day (morning, noon, evening. Using a dosimeter (ESM-140 Maschek Electronics, we obtained an exposure profile over 24 hours for three mobile phone frequency ranges (measurement interval 1 second, limit of determination 0.05 V/m for each of the participants. Exposure levels over waking hours were summed up and expressed as mean percentage of the ICNIRP (International Commission on Non-Ionizing Radiation Protection reference level. Results In comparison to non-participants, parents and adolescents with a higher level of education who possessed a mobile phone and were interested in the topic of possible adverse health effects caused by mobile telecommunication network frequencies were more willing to participate in the study. The median exposure to radio frequency electromagnetic fields of children and adolescents was 0.18% and 0.19% of the ICNIRP reference level respectively

    In the context of triple play, telecommunication industry shapes itself with new industrial chain features and market structure, which exert influences on competition strategies of telecom operators. This article holds that the vertical chain of telecommunication industry is undergoing decomposition and reintegrating, horizontal chain is deepening and expanding by triple play development, and side chain is forming with business model innovation of two-sided market. This three-dimensioned industrial chain structure combines into a network structure of industrial chain, in which industrial convergence strengthens contestable feature of telecommunication industry while network externality strengthens monopolistic feature. These opposite and complementary effects of competition and monopoly form a competitive monody structure of telecommunication industry. Accordingly, these network structure of industrial chain and competitive monopoly market structure demand telecom operators implement a comprehensive competitive strategy based on compound industrial chains.%“三网融合”发展背景下,电信产业呈现出新的产业链形态和市场结构特征,并影响了电信运营商的市场竞争策略。本文认为在电信纵向产业链分解与重组的基础上,“三网融合”深化和扩展了电信横向产业链,电信商业模式创新形成了基于双边市场的电信侧向产业链,纵向、横向和侧向三个维度的产业链相互交织形成了网状化产业链形态。这种变化一方面通过产业融合增强了电信产业的可竞争性,另一方面通过网络外部性机制增强了电信产业的可垄断性,两种相反相成的竞争效应共同形成了“三网融合”特有的竞争性垄断市场结构.网状化产业链形态和竞争性垄断市场结构促使电信运营商实行复合产业链竞争策略。

    1996-12-01

    Healthcare providers interested in forming delivery networks to secure managed care contracts must decide how to structure their networks. Two basic structural models are available: the noncorporate model and the corporate model. The noncorporate model delivery network typically has a single governing body and management infrastructure to oversee only managed care contracting and related business. The corporate model delivery system has a unified governance management infrastructure that handles all of the network's business. While either structure can work, corporate model networks usually are better able to enforce provider behavior that is in the best interest of a network as a whole. PMID:10163003

  7. Evolution and convergence in telecommunications

    International Nuclear Information System (INIS)

    These lectures throw a spotlight on different aspects of the evolution of telecommunications networks, namely on the various facets of service and network convergence. The last years progress in data and telecommunications technologies, such as P-based networks, and the enormous potential of mobile communication systems and users' demands for comprehensive and network-independent have led to a convergence of data and telecommunications infrastructures in many aspects. In order to help the reader to an easier understanding of the phenomenon convergence, in the first two parts of this volume the evolution of the basic technologies is described one by one. This is done briefly and is focused on the principle topics, just to build a basis for the third part devoted to problems of convergence in telecommunications. These notes are addressed to those readers, who in a quick overview want to be informed on the future service and network landscape. The notes are equally suited for professionals with the desire to extend their horizon as well as for students looking for an introduction into telecommunications under more general aspects. The authors clearly understand the difficulties in writing a book devoted to the evolution in telecommunications. Today, telecom landscape varies at very high speed. Every few months new network technologies, new products and new services are developed. Attempts to present them in time can be accessible only for magazine publications or contributions to conferences. Therefore, in a number of areas, such as Voice over IP and new switching technologies not much more than the starting point of new paradigms is described. However, the content is up-to-date to a degree, that the phenomenon convergence can be fully understood. Partially, these notes are based on a number of lecture courses that were delivered during recent ICTP winter schools devoted to multimedia and digital communications

  14. Single-chip MEMS 5 × 5 and 20 × 20 double-pole single-throw switch arrays for automating telecommunication networks

    International Nuclear Information System (INIS)

    This paper reports on microelectromechanical (MEMS) switch arrays with 5 × 5 and 20 × 20 double-pole single-throw (DPST) switches embedded and packaged on a single chip, which are intended for automating main distribution frames in copper-wire telecommunication networks. Whenever a customer requests a change in his telecommunication services, the copper-wire network has to be reconfigured which is currently done manually by a costly physical re-routing of the connections in the main distribution frames. To reduce the costs, new methods for automating the network reconfiguration are sought after by the network providers. The presented devices comprise 5 × 5 or 20 × 20 double switches, which allow us to interconnect any of the 5 or 20 input lines to any of the 5 or 20 output lines. The switches are based on an electrostatic S-shaped film actuator with the switch contact on a flexible membrane, moving between a top and a bottom electrode. The devices are fabricated in two parts which are designed to be assembled using selective adhesive wafer bonding, resulting in a wafer-scale package of the switch array. The on-chip routing network consists of thick metal lines for low resistance and is embedded in bencocyclobutene (BCB) polymer layers. The packaged 5 × 5 switch arrays have a size of 6.7 × 6.4 mm2 and the 20 × 20 arrays are 14 × 10 mm2 large. The switch actuation voltages for closing/opening the switches averaged over an array were measured to be 21.2 V/15.3 V for the 5 × 5 array and 93.2 V/37.3 V for the 20 × 20 array, respectively. The total signal line resistances vary depending on the switch position within the array between 0.13 Ω and 0.56 Ω for the 5 × 5 array and between 0.08 Ω to 2.33 Ω for the 20 × 20 array, respectively. The average resistance of the switch contacts was determined to be 0.22 Ω with a standard deviation of 0.05 Ω

    The routingtelecommunication networksbeing one of key issues of management influences the switch rate and load balance directly, and becomes more and more important as the telecommunication traffic increases at full speed. It was said that raising one percent of switch rate of current Chinese telecommunication networks would result in revenue about one billion Yuan RMB. On the basis of demerit-analysis of routing scheme being used, a new intelligent routing strategy based on multi-agent systems and recurrent neural network predication is presented, including routing strategy, Calls generating and agent~ recurrent neural network computation, simulation software design, results and discussion. The results show that the new one is better by virtue of its upstanding distribution and intelligence characters, and provides excellent solution to increase network switch rate and balance network load. Meanwhile, its applications will go beyond the scope of telecommunication networks. But whether the strategy will be perfect depends on the cooperation among operator, manufacturer and researchers.

    The development and state of the art is presented for inpatient psychotherapy in neurotic and psychosomatic patients. The question is then posed whether time-tested inpatient psychotherapy can survive the introduction of "diagnosis-related groups" (DRG) with its threat of flat-rate case billing. Thus, the development of an "in- and outpatient network" has been considered as a possible alternative, in which hospitals and private practices combine intervals of inpatient and outpatient psychotherapy.

    2016-01-01

    As part of long-term care reforms, home-care organisations in the Netherlands are required to strengthen the linkage between formal and informal caregivers of home-dwelling older adults. Information on the variety in mixed care networks may help home-care organisations to develop network type-dependent strategies to connect with informal caregivers. This study first explores how structural (size, composition) and functional features (contact and task overlap between formal and informal caregivers) contribute to different types of mixed care networks. Second, it examines to what degree these network types are associated with the care recipients' characteristics. Through home-care organisations in Amsterdam, the Netherlands, we selected 74 frail home-dwelling clients who were receiving care in 2011-2012 from both informal and formal caregivers. The care networks of these older adults were identified by listing all persons providing help with five different types of tasks. This resulted in care networks comprising an average of 9.7 caregivers, of whom 67% were formal caregivers. On average, there was contact between caregivers within 34% of the formal-informal dyads, and both caregivers carried out at least one similar type of task in 29% of these dyads. A principal component analysis of size, composition, contact and task overlap showed two distinct network dimensions from which four network types were constructed: a small mixed care network, a small formal network, a large mixed network and a large formal network. Bivariate analyses showed that the care recipients' activities of daily living level, memory problems, social network, perceived control of care and level of mastery differed significantly between these four types. The results imply that different network types require different actions from formal home-care organisations, such as mobilising the social network in small formal networks, decreasing task differentiation in large formal networks and assigning

  13. Study on Theory and Methods of Telecommunication Tariff

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The pricing of telecommunication services is quite important aswell as complicated. This paper strengthens the research of theories and implementation of telecommunication tariff in China. It is helpful for the government authorities and enterprises to unify and standardize the regulatory methods, to guide the deciding of the structure and level of telecommunication tariff by implementing scientific theories, to further develop and optimize the tariff system. This paper conducts a systematic, in-depth and creative research on some of the most popular and most difficult problems in the area of telecommunication tariff research, such as the regulation of telecommunication tariff, the theories of telecommunication tariff, the systematic pricing theory, the interconnection charge, the model cost evaluation theory, the long-run incremental cost theory, and the international telecommunication tariff. After studying the foreign methods on telecommunication tariff regulation, basing on the current situation of China's tariff regulation, the scope and methods for China's telecommunication tariff regulation are suggested. Aimed at the weakness of pricing theory for enterprises to set up telecommunication tariffs, an overall frame work of telecommunication tariff theories is proposed. The systematic pricing theory and model cost evaluation theory of telecommunication services are put forward from a brand new perspective. A front topic, the LRIC theory, is probed. In addition, the pricing practices of network interconnection charge and international telecommunication tariff, which are currently very attractive to the theorists, are discussed. Basing on these studies, this paper improves the structure of telecommunication tariff theory. It provides the Chinese government authorities with practical methods and helpful supports to regulate the telecommunication tariffs; in the mean time, it also provides the enterprises with scientific pricing theories and methods to set up

    Although hospital-owned primary care practices have been unprofitable for most hospitals, some hospitals are achieving competitive advantage and sustainable practice operations. A key to the success of some has been a net income reporting tool that separates practice operating expenses from the costs of creating and operating a network of practices to help healthcare organization managers, physicians, and staff to identify opportunities to improve the network's financial performance. This "Net One, Net Two" reporting allows operations leadership to be held accountable for Net One expenses and strategic leadership to be held accountable for Net Two expenses. PMID:11066669

    2014-01-01

    A detailed review was conducted of the literature on models evaluating the effectiveness of integrated and coordinated care networks for the older population. The search made use of the following bibliographic databases: Pubmed, The Cochrane Library, LILACS, Web of Science, Scopus and SciELO. Twelve articles on five different models were included for discussion. Analysis of the literature showed that the services provided were based on primary care, including services within the home. Service users relied on the integration of primary and hospital care, day centers and in-home and social services. Care plans and case management were key elements in care continuity. This approach was shown to be effective in the studies, reducing the need for hospital care, which resulted in savings for the system. There was reduced prevalence of functional loss and improved satisfaction and quality of life on the part of service users and their families. The analysis reinforced the need for change in the approach to health care for older adults and the integration and coordination of services is an efficient way of initiating this change.

    2007-01-01

    This essay analyzes the data of Chinese telecommunication market, telecommunication investments and investment benefits over the past 20 years. On the basis of these data, the essay reviews Chinese changing telecommunication policies and discusses the major events in the course of China's telecommunication development. It is argued that telecommunication policies, regime backgrounds and market demand characteristics have a significant impact on investment decision mode in telecommunication industry. The evolution of network investments decision mode in China's telecommunication has corresponded to the transformation of these key factors. Considering the special events in the development of Chinese telecommunication as divisions, the essay discusses three stages of the evolution of investments decision mode in China's telecommunication. With the firm environment and problems that Chinese telecommunication operators have been facing since 2000 analyzed. it is demonstrated that Chinese telecommunication operators should change their mode of investment decision into the "profit-oriented investment decision mode" in order to achieve a high growth performance in the capital market,. This investment decision mode will result in increase of the investment profit with limited investment capital. The main procedure of profit-oriented investment decision mode is set out, which is abstracted to a mathematical model eventually.

    2008-01-01

    We explain why some caretakers opt for alternative medicine for the treatment of children's asthma whereas others do not. In the past 15 years, asthma care has been standardized, with clinical practice guidelines centered on advanced pharmacological regimes. Clinicians argue that with proper biomedical treatment and environmental control, asthma should be a manageable chronic disease. Yet many patients forego available pharmacological treatments for alternative medicine or complement prescribed drugs with unconventional treatments. On the basis of open-ended, in-depth qualitative interviews with 50 mothers of children with asthma, we argue that the experience with biomedical treatments, social influence in mother's network of care, concerns about adverse and long-term effects, health care providers' responsiveness to such concerns, and familiarity with alternative treatments explain why some families rely on alternative medicine and others do not.

    Directory of Open Access Journals (Sweden)

    Mariana Kaneva

    2016-07-01

    Full Text Available The relationship between telecommunications infrastructure and economic activity is under discussion in many scientific papers. Most of the authors use for research and analysis the Jipp curve. A lot of doubts about the correctness of the Jipp curve appear in terms of applying econometric models. The aim of this study is a review of the Jipp curve, refining the possibility of its application in modern conditions. The methodology used in the study is based on dynamic econometric models, including tests for nonstationarity and tests for causality. The focus of this study is directed to methodological problems in measuring the local density types of telecommunication networks. This study offers a specific methodology for assessing the Jipp law, through VAR-approach and Granger causality tests. It is proved that mechanical substitution of momentary aggregated variables (such as the number of subscribers of a telecommunication network at the end of the year and periodically aggregated variables (such as GDP per capita in the Jipp�s curve is methodologically wrong. Researchers have to reconsider the relationship set in the Jipp�s curve by including additional variables that characterize the Telecommunications sector and the economic activity in a particular country within a specified time period. GDP per capita should not be regarded as a single factor for the local density of telecommunications infrastructure. New econometric models studying the relationship between the investments in telecommunications infrastructure and economic development may be not only linear regression models, but also other econometric models. New econometric models should be proposed after testing and validating with sound economic theory and econometric methodology.

    Babulak, Eduard

    2006-01-01

    The continuous increase in the complexity and the heterogeneity of corporate and healthcare telecommunications infrastructures will require new assessment methods of quality of service (QoS) provision that are capable of addressing all engineering and social issues with much faster speeds. Speed and accessibility to any information at any time from anywhere will create global communications infrastructures with great performance bottlenecks that may put in danger human lives, power supplies, national economy and security. Regardless of the technology supporting the information flows, the final verdict on the QoS is made by the end user. The users' perception of telecommunications' network infrastructure QoS provision is critical to the successful business management operation of any organization. As a result, it is essential to assess the QoS Provision in the light of user's perception. This article presents a cost effective methodology to assess the user's perception of quality of service provision utilizing the existing Staffordshire University Network (SUN) by adding a component of measurement to the existing model presented by Walker. This paper presents the real examples of CISCO Networking Solutions for Health Care givers and offers a cost effective approach to assess the QoS provision within the campus network, which could be easily adapted to any health care organization or campus network in the world.

It was sponsored by NATO's Special Programme Panel on Systems Science and took place, in September 1977, at the University of Bergamo in the north of Italy. Telecommunication systems which provide for communication be­ tween people, rather than computers or other instruments, are of two kinds. There are mass communication systems (broadcast radio and television) and interpersonal systems (for example, the telephone and Telex) which join together individuals or small groups. Here we have included in the interpersonal category certain systems for re­ trieving information from computers, essentially those systems in which the role of the computer 1s primarily to act as a store and to identify that information which best fits a user's request.

  12. Accelerating a Network Model of Care: Taking a Social Innovation to Scale

    Directory of Open Access Journals (Sweden)

    2012-07-01

    Full Text Available Government-funded systems of health and social care are facing enormous fiscal and human-resource challenges. The space for innovation in care is wide open and new disruptive patterns are emerging. These include self-management and personal budgets, participatory and integrated care, supported decision making and a renewed focus on prevention. Taking these disruptive patterns to scale can be accelerated by a technologically enabled shift to a network model of care to co-create the best outcomes for individuals, family caregivers, and health and social care organizations. The connections, relationships, and activities within an individual’s personal network lay the foundation for care that health and social care systems/policy must simultaneously support and draw on for positive outcomes. Practical tools, adequate information, and tangible resources are required to coordinate and sustain care. Tyze Personal Networks is a social venture that uses technology to engage and inform the individual, their personal networks, and their care providers to co-create the best outcomes. In this article, we demonstrate how Tyze contributes to a shift to a network model of care by strengthening our networks and enhancing partnerships between care providers, individuals, and family and friends.

    The Los Angeles Free-Net, an interactive community information resource, was established in part to help community members become more effective consumers of health care services. By providing timely, expert answers to anonymously asked medical questions at no charge, we hope to decrease unnecessary physician-patient encounters, encourage effective preventive-health measures, and improve the overall results of health care in our community. Although it is too early to assess health care benefits from this system, the following observations may help guide the development of similar systems around the nation: (1) A small annual registration fee generates both moral and financial public support. (2) Demographic information from registered users can help direct attempts at enfranchising all members of the community. (3) Toll-free access, free public-instruction sessions, moderated forums, extensive volunteer help, and encryption security are encouraged, while Internet censorship is difficult and counterproductive. (4) Access to Internet resources is important, but the strength of a community system lies primarily in the sharing of expertise and resources among members of the community. (5) A critical mass of available physicians to answer questions must be matched with a critical level of question input for this type of interactive medical information resource to function in a time-sensitive fashion.

    The end of the Second World War saw global telecommunications governance renegotiated. The dominant British Imperial (later Commonwealth) network experienced multiple changes: the tightly integrated and collaborative imperial governance system fell away as the governing partners increasingly pursued their own, rather than a collective agendas and as the ‘imperial’ company, Cable and Wireless', dominance gave way to a competition and interconnection based regime as American firms and their net...

  19. Medical image telecommunication

    International Nuclear Information System (INIS)

    After years of waiting for Picture Archiving and Communication Systems (PACS) to become technologically mature and readily available at competitive costs, it appears that the ingredients are now available for producing at least the telecommunication component of the PACS. They are as follows: 1. A variety of pathways now exist for long-distance high-speed digital data transmission at acceptable costs. 2. Developments in computer technology and keen competition in the microcomputer and video display markets have markedly reduced to costs for components of digital data terminals. 3. The volume of native digitally acquired images is expanding yearly, whereas at the same time the pressure for converting images acquired in analog format to digital format is increasing. 4. The advantages of and potential for processing and storing imaging data in digital format are becoming more widely recognized. These factors, individually and collectively, favor the successful applications of image telecommunication to the field of diagnostic imaging. The authors have attempted to provide an overview of the subject and the basics of this emerging technology

    This paper presents the sensor network infrastructure for a home care system that allows long-term monitoring of physiological data and everyday activities. The aim of the proposed system is to allow the elderly to live longer in their home without compromising safety and ensuring the detection of health problems. The system offers the possibility of a virtual visit via a teleoperated robot. During the visit, physiological data and activities occurring during a period of time can be discussed. These data are collected from physiological sensors (e.g., temperature, blood pressure, glucose) and environmental sensors (e.g., motion, bed/chair occupancy, electrical usage). The system can also give alarms if sudden problems occur, like a fall, and warnings based on more long-term trends, such as the deterioration of health being detected. It has been implemented and tested in a test environment and has been deployed in six real homes for a year-long evaluation. The key contribution of the paper is the presentation of an implemented system for ambient assisted living (AAL) tested in a real environment, combining the acquisition of sensor data, a flexible and adaptable middleware compliant with the OSGistandard and a context recognition application. The system has been developed in a European project called GiraffPlus. PMID:24573309

    2009-01-01

    Health care in the United States is a system that, organizationally speaking, is fragmented. Each hospital facility is independently operated and is responsible for the hiring of its own employees. Corrupt individuals can take advantage of this fragmentation and move from hospital to hospital, gaining employment while hiding previous employment history. However, the need to exchange pertinent information regarding employees will become necessary as hospitals seek to fill positions throughout their organizations. One way to promote this information exchange is to develop trusted information sharing networks among hospital units. This study examined the problems surrounding organizational information sharing and the cultural factors necessary to enhance the exchange of employee information. Surveys were disseminated to 2,603 hospital chief executive officers and chief information officers throughout the nation. A sample of 154 respondents provided data into their current hiring practices and on their willingness to engage in the sharing of employee information. Findings indicated that, although fear of defamation and privacy violations do hinder the exchange of information between hospitals during the hiring process, by increasing external trust, linking the sharing process with the organizational goals of the hospital, and developing a "sharing culture" among hospitals, the exchange of employee information could be enhanced.

    Full Text Available AIM: Guideline implementation programs are of paramount importance in optimizing acute ST-elevation myocardial infarction (STEMI care. Assessment of performance indicators from a local STEMI network will provide knowledge of how to improve the system of care. METHODS AND RESULTS: Between 2008-2011, 1505 STEMI patients were enrolled. We compared the performance indicators before (n = 869 and after implementation (n = 636 of a local STEMI network. In 2011 (after introduction of STEMI networking compared to 2008-2010, there were more inter-hospital referrals for STEMI patients (61% vs 56%, p12 hours after symptom onset were similar (53% vs 51%, NS. Moreover, the numbers of patients with door-to-balloon time ≤ 90 minutes were similar (49.1% vs 51.3%, NS, and in-hospital mortality rates were similar (8.3% vs 6.9%, NS in 2011 compared to 2008-2010. CONCLUSION: After a local network implementation for patients with STEMI, there were significantly more inter-hospital referral cases, primary PCI procedures, and patients with a door-to-needle time ≤ 30 minutes, compared to the period before implementation of this network. However, numbers of patients who presented very late, the targeted door-to-balloon time and in-hospital mortality rate were similar in both periods. To improve STEMI networking based on recent guidelines, existing pre-hospital and in-hospital protocols should be improved and managed more carefully, and should be accommodated whenever possible.

    Full Text Available This article examines the processes of technical mediation within familial care networks based on a study of home telecare targeted at older people. Supported by contributions from the actor—network theory as part of the social psychology of science and technology, these processes of technical mediation are analyzed using a qualitative approach. The data were gathered through six focus groups and four in-depth interviews; the participants in the study included users, relatives and formal carers. Thematic analysis techniques encompassing the information were used, revealing the effects on the patterns of caring relationships. The results show the interplay between presence-absence made possible by the devices; the two-way direction of care between the older people and the artifacts; and the process of sustaining care using the technology. We conclude that care should be seen as a socio-technical network where technology plays an active role in sustaining family relationships.

    Full Text Available Abstract Background Older people's social networks with family and friends can affect residential aged care use. It remains unclear if there are differences in the effects of specific (with children, other relatives, friends and confidants and total social networks upon use of low-level residential care and nursing homes. Methods Data were drawn from the Australian Longitudinal Study of Ageing. Six waves of data from 1477 people aged ≥ 70 collected over nine years of follow-up were used. Multinomial logistic regressions of the effects of specific and total social networks on residential care use were carried out. Propensity scores were used in the analyses to adjust for differences in participant's health, demographic and lifestyle characteristics with respect to social networks. Results Higher scores for confidant networks were protective against nursing home use (odds ratio [OR] upper versus lower tertile of confidant networks = 0.50; 95%CI 0.33–0.75. Similarly, a significant effect of upper versus lower total network tertile on nursing home use was observed (OR = 0.62; 95%CI 0.43–0.90. Evidence of an effect of children networks on nursing home use was equivocal. Nursing home use was not predicted by other relatives or friends social networks. Use of lower-level residential care was unrelated to social networks of any type. Social networks of any type did not have a significant effect upon low-level residential care use. Discussion Better confidant and total social networks predict nursing home use in a large cohort of older Australians. Policy needs to reflect the importance of these particular relationships in considering where older people want to live in the later years of life.

  15. Telecommunications, politics, economics, and national sovereignty: A new game

    The impact of telecommunications on politics, economics and national sovereignty is creating a new game. Political and economic power may operate over the same territory, as in the now-rare case of isolated economies, but, more often, their domains do not coincide. Increasingly, telecommunications create major challenges for countries preoccupied with issues of national sovereignty because the national state has only a limited ability to control these intrinsic and at times potentially destabilizing powers of telecommunications and the {open_quotes}telecommunities{close_quotes} they make possible. As many traditional aspects of sovereignty are becoming weakened by telecommunications, and as the intense dynamics of networks and the expansion of telecommunities revolutionize business and politics, there is a need to prevent the situation from becoming chaotic and uncontrollable, even while recognizing the possibilities of enhanced opportunities. This requires focusing on a more flexible conception of sovereignty which can enhance the state`s attractiveness for telecommunications infrastructure, while addressing issues of ethics and morality in the new telecommications environment. A new, broad socio-technological research agenda needs to be developed - with the ultimate purpose of providing society with the tools to play the new game and thrive. 10 refs., 3 tabs.

    The Family Health Strategy Service (FHSS) is an important ally in the mental health system, contributing to the completeness and effectiveness of care. This study aimed to discuss the mental health care network as compared to the daily routine of an FHSS. It is an evaluative study with a qualitative methodological approach. It was developed in an FHSS in Porto Alegre-RS, Brazil. Data was collected between July and December of 2010 through interviews with 16 workers and ten relatives. We identified important resources in primary health care, such as partnerships with academia. However, the constitution of this care is still based on specialty, following the logic of patient referral. Our intention for this study was to contribute to the operationalization of the mental health care network, consolidating the partnership with the FHSS and developing activities in the territorial space, raising awareness, demystifying health care service in the area, and countering the perception that it is uniquely specialized.

    In this article, a clustering method based on genetic algorithm (GA) for telecommunication customer subdivision is presented. First, the features of telecommunication customers (such as the calling behavior and consuming behavior) are extracted. Second, the similarities between the multidimensional feature vectors of telecommunication customers are computed and mapped as the distance between samples on a two-dimensional plane. Finally, the distances are adjusted to approximate the similarities gradually by GA. One advantage of this method is the independent distribution of the sample space. The experiments demonstrate the feasibility of the proposed method.

    Pediatric health care networks serve millions of children each year. Pediatric illness and injury are among the most common potentially emotionally traumatic experiences for children and their families. In addition, millions of children who present for medical care (including well visits) have been exposed to prior traumatic events, such as violence or natural disasters. Given the daily challenges of working in pediatric health care networks, medical professionals and support staff can experience trauma symptoms related to their work. The application of a trauma-informed approach to medical care has the potential to mitigate these negative consequences. Trauma-informed care minimizes the potential for medical care to become traumatic or trigger trauma reactions, addresses distress, provides emotional support for the entire family, encourages positive coping, and provides anticipatory guidance regarding the recovery process. When used in conjunction with family-centered practices, trauma-informed approaches enhance the quality of care for patients and their families and the well-being of medical professionals and support staff. Barriers to routine integration of trauma-informed approaches into pediatric medicine include a lack of available training and unclear best-practice guidelines. This article highlights the importance of implementing a trauma-informed approach and offers a framework for training pediatric health care networks in trauma-informed care practices. PMID:26571032

    2002-09-01

    The Telecom Act of 1996 was intended to address the lack of competition and reduce regulation in local telephone services and in other areas of the telecommunications sector. The competitive situation in telecommunications, particularly regarding local telephone services, has experienced a limited amount of positive change as a result of the Act. Local Telephone service consumers are still given little choice as the Incumbent Local Exchange Carriers (ILECs) continue to dominate coverage in the local loop. The purpose of this thesis is to demonstrate the effects that the situation resulting from the Act had on the expansion of telecommunications options and the emergence of new technologies. This thesis also focuses on exploring to what degree competition in telecommunications has improved since 1996. Case studies of telecom companies are utilized to demonstrate how effective the regulations of the Act were in various telecom areas such as long-distance and local services. The convergence of technologies and applications is also identified as several providers combined to offer services such as Web hosting, Voice Over IP solutions, wireless, and long-distance. Problems such as the need for new networks in the local loop are identified and recommendations for potential solutions in the telecom industry are also given.

    This article reviews the current issues and advancements in social network approaches to HIV prevention and care. Social network analysis can provide a method to understand health disparities in HIV rates, treatment access, and outcomes. Social network analysis is a valuable tool to link social structural factors to individual behaviors. Social networks provide an avenue for low-cost and sustainable HIV prevention interventions that can be adapted and translated into diverse populations. Social networks can be utilized as a viable approach to recruitment for HIV testing and counseling, HIV prevention interventions, optimizing HIV medical care, and medication adherence. Social network interventions may be face-to-face or through social media. Key issues in designing social network interventions are contamination due to social diffusion, network stability, density, and the choice and training of network members. There are also ethical issues involved in the development and implementation of social network interventions. Social network analyses can also be used to understand HIV transmission dynamics.

    Full Text Available Paper presents telecommunications security issues with dynamically changing networking. Paper also presents performance indicators of authentication as an integral part of the approach to non-public information. Expected level of security depend on relevant ITS services requirements, different solutions require different levels of quality. Data volumes transferred both in private data vehicle on board networks as well as between vehicles and infrastructure or other vehicles significantly and progressively grow. This trend leads to increase of the fatal problems if security of the wide area networks is not relevantly treated. Relevant communications security treatment becomes crucial part of the ITS telecommunications solution because probability of hazards appearances grow if vehicles networks are integrated in the dynamically organized wide area networks. Besides of available "off shelf" security tools solution based on non-public universal identifier with dynamical extension and data selection according to actor role or category is presented including performances indicators for the authentication process.

The two main factors that affect the growth of telecommunications are the rapid growth of modern technology and the market demand and its competition. These two factors in return, create new technologies and products, which open a series of options and offers to customers, in order to satisfy their needs and requirements. However, one crucial problem that commercial companies in general and telecommunication in particular, suffer from is a loss of valuable customers to competitors; this is called customer churn prediction. In this paper, the dynamic training technique is introduced. The dynamic training is used to improve the prediction of performance. This technique is based on two ANN network configurations to minimise the total error of the network to predict two different classes; names churn and non-customers.

This study presents the results of a multisite card study organized by The Collaborative Care Research Network, a subnetwork of the American Academy of Family Physicians' National Research Network devoted to conducting practice-based research focused on the provision of BH and health behavior services within primary care practices. The goals of the study included: (1) identifying the characteristics of patients referred for BH services; (2) codifying reasons for referral and whether patients were treated for the referral; (3) exploring any differences between patients who initiated BH contact and those who did not; and (4) assessing the types and frequency of BH services provided to patients who attended at least one appointment. Of the 200 patients referred to a BHP, 81 % had an initial contact, 71 % of which occurred on the same day. Men and women were equally likely to engage with a BHP although the time between appointments varied by gender. Depression and anxiety were the primary reasons for referral. Practice-based research is a viable strategy for advancing the knowledge about integrated primary care. PMID:24073133

  18. Clinical and regulatory protocols for the management of impaired vision in the public health care network

    Directory of Open Access Journals (Sweden)

    Jayter Silva Paula

    2011-06-01

    Full Text Available PURPOSE: To describe the procedures used in developing Clinical and Regulatory Protocols for primary care teams to use in the management of the most common scenarios of impaired vision in Southern Brazil. METHODS: A retrospective review of 1.333 referral forms from all primary care practitioners was performed in Ribeirão Preto city, during a 30-day period. The major ophthalmic diagnostic categories were evaluated from those referrals forms. The Clinical and Regulatory Protocols development process was held afterwards and involved scientific cooperation between a university and the health care system, in the form of workshops attended by primary care practitioners and regulatory system team members composed of health care administrators, ophthalmologists, and professors of ophthalmology and social medicine. RESULTS: The management of impaired vision was chosen as the theme, since it accounted for 43.6% of the ophthalmology-related referrals from primary care providers of Ribeirão Preto. The Clinical and Regulatory Protocols developed involve distinctive diagnostic and therapeutic interventions that can be performed at the primary care level and in different health care settings. The most relevant clinical and regulatory interventions were expressed as algorithms in order to facilitate the use of the Clinical and Regulatory Protocols by health care practitioners. CONCLUSIONS: These Clinical and Regulatory Protocols could represent a useful tool for health systems with universal access, as well as for health care networks based on primary care and for regulatory system teams. Implementation of these Clinical and Regulatory Protocols can minimize the disparity between the needs of patients with impaired vision and the treatment modalities offered, resulting in a more cooperative health care network.

  19. SAT-Based Complete Don't-Care Computation for Network Optimization

    CERN Document Server

    Mishchenko, Alan

    2011-01-01

    This paper describes an improved approach to Boolean network optimization using internal don't-cares. The improvements concern the type of don't-cares computed, their scope, and the computation method. Instead of the traditionally used compatible observability don't-cares (CODCs), we introduce and justify the use of complete don't-cares (CDC). To ensure the robustness of the don't-care computation for very large industrial networks, a optional windowing scheme is implemented that computes substantial subsets of the CDCs in reasonable time. Finally, we give a SAT-based don't-care computation algorithm that is more efficient than BDD-based algorithms. Experimental results confirm that these improvements work well in practice. Complete don't-cares allow for a reduction in the number of literals compared to the CODCs. Windowing guarantees robustness, even for very large benchmarks on which previous methods could not be applied. SAT reduces the runtime and enhances robustness, making don't-cares affordable for a v...

    Most primary care physicians do not treat obesity, citing lack of time, resources, insurance reimbursement, and knowledge of effective interventions as significant barriers. To address this need, a 10-minute intervention delivered by the primary care physician was coupled with individual dietary counseling sessions delivered by a registered dietitian via telephone with an automated calling system (House-Calls, Mobile, AL). Patients were seen for follow-up by their physician at weeks 4, 12, 24, 36 and 52. A total of 252 patients (202 women and 50 men) were referred by 18 primary care physicians to the program. The comorbid conditions reported for all patients at baseline included low back pain, 29% (n = 72); hypertension, 45% (n = 113); hypercholesterolemia, 41% (n = 104); type 2 diabetes, 10% (n = 26); and sleep apnea, 5% (n = 12). When offered a choice of meal plans based on foods or meal replacements, two-thirds of patients (n = 166) chose to use meal replacements (Ultra Slim-Fast; Slim-Fast Foods Co., West Palm Beach, FL) at least once daily. Baseline weights of subjects averaged 200 +/- 46 lb for women (n = 202) and 237 +/- 45 lb for men (n = 50). Patients completing 6 months in the program lost an average of 19.0 +/- 4.0 lb for women (n = 94) and 15.5 +/- 8.2 lb for men (n = 26). Physicians reported a high degree of satisfaction with the program, suggesting that a brief, effective physician-directed program with nutritionist support by telephone can be implemented in a busy primary care office.

    2008-07-01

    Partnerships represent a prescriptive form of network governance, based on the idea of cooperation. This article has four aims. The first is to describe why network governance and partnerships are important now, and what one particular example - Primary Care Partnerships - is addressing. The second is to analyse the network structure of two of these partnerships, and the third is to examine network dynamics. The fourth aim is to explore relationships and sustainability over the longer term. Two government-funded and steered partnerships, which were established to increase coordination between primary care services in Victoria, Australia, were examined. Annual interviews at three points in time between 2002 and 2005 were used to explore relationships between organizations within these two partnerships. The structure of two different communication networks, based on contacts for work and contacts for strategic information, were examined using social network analysis. Tracing network structures over time highlighted partnership dynamics. The network structures changed over the three years of the study, but an important constant was the continuing centrality of the independent staff employed to manage the partnerships. Over the longer term, it seems to be more important to fund independent partnership staff, rather than people who connect partnerships to the funding agency. If partnerships are seen as valuable in improving service coordination and health outcomes, then long term rather than just start-up funding support is required. PMID:18472201

    Clinical networks for paediatric and adolescent rheumatology are evolving, and their effect and role in the transition process between paediatric and adult services are unknown. We therefore explored the experiences of those involved to try and understand this further. Health professionals, young people with juvenile idiopathic arthritis and their families were recruited via five national health service paediatric and adolescent rheumatology specialist centres and networks across the UK. Seventy participants took part in focus groups and one-to-one interviews. Data was analysed using coding, memoing and mapping techniques to identify features of transitional services across the sector. Variation and inequities in transitional care exist. Although transition services in networks are evolving, development has lagged behind other areas with network establishment focusing more on access to paediatric rheumatology multidisciplinary teams. Challenges include workforce shortfalls, differences in service priorities, standards and healthcare infrastructures, and managing the legacy of historic encounters. Providing equitable high-quality clinically effective services for transition across the UK has a long way to go. There is a call from within the sector for more protected time, staff and resources to develop transition roles and services, as well as streamlining of local referral pathways between paediatric and adult healthcare services. In addition, there is a need to support professionals in developing their understanding of transitional care in clinical networks, particularly around service design, organisational change and the interpersonal skills required for collaborative working. Key messages • Transitional care in clinical networks requires collaborative working and an effective interface with paediatric and adult rheumatology.• Professional centrism and historic encounters may affect collaborative relationships within clinical networks.• Education

  8. Fuzzy bi-objective preventive health care network design.

    Davari, Soheil; Kilic, Kemal; Ertek, Gurdal

    2015-09-01

    Preventive health care is unlike health care for acute ailments, as people are less alert to their unknown medical problems. In order to motivate public and to attain desired participation levels for preventive programs, the attractiveness of the health care facility is a major concern. Health economics literature indicates that attractiveness of a facility is significantly influenced by proximity of the clients to it. Hence attractiveness is generally modelled as a function of distance. However, abundant empirical evidence suggests that other qualitative factors such as perceived quality, attractions nearby, amenities, etc. also influence attractiveness. Therefore, a realistic measure should incorporate the vagueness in the concept of attractiveness to the model. The public policy makers should also maintain the equity among various neighborhoods, which should be considered as a second objective. Finally, even though the general tendency in the literature is to focus on health benefits, the cost effectiveness is still a factor that should be considered. In this paper, a fuzzy bi-objective model with budget constraints is developed. Later, by modelling the attractiveness by means of fuzzy triangular numbers and treating the budget constraint as a soft constraint, a modified (and more realistic) version of the model is introduced. Two solution methodologies, namely fuzzy goal programming and fuzzy chance constrained optimization are proposed as solutions. Both the original and the modified models are solved within the framework of a case study in Istanbul, Turkey. In the case study, the Microsoft Bing Map is utilized in order to determine more accurate distance measures among the nodes. PMID:25171939

    Converting the health care delivery system into a learning organization is a key strategy for improving health outcomes. While the learning organization approach has been successful in neonatal intensive care units and disease specific collaboratives there are few examples in general medicine and fewer still have leveraged the role of hospitalists to implement improvements. This paper describes the rationale for and early work of the Hospital Medicine Reengineering Network (HOMERuN), a collaborative of hospitals, hospitalists, and care teams whose overarching purpose is to use data to guide collaborative efforts aimed at improving the care of hospitalized patients. We review HOMERuN’s collaborative model, which focuses on a community-based participatory approach modified to include hospital-based as well as the larger community, and HOMERuN’s initial project focusing on care transition improvement using perspectives from the patient and caregiver.

  11. Standby battery requirements for telecommunications power

    Science.gov (United States)

    May, G. J.

    The requirements for standby power for telecommunications are changing as the network moves from conventional systems to Internet Protocol (IP) telephony. These new systems require higher power levels closer to the user but the level of availability and reliability cannot be compromised if the network is to provide service in the event of a failure of the public utility. Many parts of these new networks are ac rather than dc powered with UPS systems for back-up power. These generally have lower levels of reliability than dc systems and the network needs to be designed such that overall reliability is not reduced through appropriate levels of redundancy. Mobile networks have different power requirements. Where there is a high density of nodes, continuity of service can be reasonably assured with short autonomy times. Furthermore, there is generally no requirement that these networks are the provider of last resort and therefore, specifications for continuity of power are directed towards revenue protection and overall reliability targets. As a result of these changes, battery requirements for reserve power are evolving. Shorter autonomy times are specified for parts of the network although a large part will continue to need support for hours rather minutes. Operational temperatures are increasing and battery solutions that provide longer life in extreme conditions are becoming important. Different battery technologies will be discussed in the context of these requirements. Conventional large flooded lead/acid cells both with pasted and tubular plates are used in larger central office applications but the majority of requirements are met with valve-regulated lead/acid (VRLA) batteries. The different types of VRLA battery will be described and their suitability for various applications outlined. New developments in battery construction and battery materials have improved both performance and reliability in recent years. Alternative technologies are also being proposed

    We have designed and developed a novel data communications network targeted at the provision of Emergency Medical Care in disaster situations over wide areas. The network nodes can transmit essential biosignals and in addition, support video and diagnostic quality sound (auscultation) broadcasting for teleconsultation purposes, by using a variety of wireless transports. The medical data acquisition stations are networked dynamically and on demand, with no requirement for an existing communications infrastructure at the disaster sites. The network design allows for limited transmitting station mobility and support for software-based Voice over IP during station roaming. Initial test results, following the hardware and software integration, indicate that the chosen network design meets specifications, and a full-scale field test, utilizing a large number of wireless stations operating under realistic conditions is to take place.

    Full Text Available Objective: to understand and identify the support network and social support from the perspective of families of children with chronic conditions. Methods: a qualitative study, with content analysis of 134 records, followed by ten semi-structured interviews. Results: the analysis has revealed that the primary caregiver, the mother, participates in a network of limited support, only with the help of her husband, children, grandparents and the child´s godparents. They also have a social network through a multidisciplinary team, which in some cases is not effective. Conclusion: families have a deficient and limited support network and the demand for care rely only on the support of the husband, grandparents, children, and godparents. Social networking refers to the philanthropic institutions, while the aid of public service, basic health unit is basic.

    2010-03-01

    Full Text Available Rates of hospital-acquired infections, such as methicillin-resistant Staphylococcus aureus (MRSA, are increasingly used as quality indicators for hospital hygiene. Alternatively, these rates may vary between hospitals, because hospitals differ in admission and referral of potentially colonized patients. We assessed if different referral patterns between hospitals in health care networks can influence rates of hospital-acquired infections like MRSA. We used the Dutch medical registration of 2004 to measure the connectedness between hospitals. This allowed us to reconstruct the network of hospitals in the Netherlands. We used mathematical models to assess the effect of different patient referral patterns on the potential spread of hospital-acquired infections between hospitals, and between categories of hospitals (University medical centers, top clinical hospitals and general hospitals. University hospitals have a higher number of shared patients than teaching or general hospitals, and are therefore more likely to be among the first to receive colonized patients. Moreover, as the network is directional towards university hospitals, they have a higher prevalence, even when infection control measures are equally effective in all hospitals. Patient referral patterns have a profound effect on the spread of health care-associated infections like hospital-acquired MRSA. The MRSA prevalence therefore differs between hospitals with the position of each hospital within the health care network. Any comparison of MRSA rates between hospitals, as a benchmark for hospital hygiene, should therefore take the position of a hospital within the network into account.

    Cancer is a top concern globally. Cancer care suffers from lack of coordination, silos of information, and high cost. Interest is emerging in person-centered technology to assist with coordination to address these challenges. This study evaluates the usability of the "personal health network" (PHN), a novel solution leveraging social networking and mobile technologies, among individuals undergoing chemotherapy and receiving care coordination. Early results from interviews of 12 participants in a randomized pragmatic trial suggest that they feel more connected to the healthcare team using the PHN, find value in access to the patient education library, and are better equipped to organize the many activities that occur during chemotherapy. Improvements are needed in navigation, connectivity, and integration with electronic health records. Findings contribute to improvements in the PHN and informs a roadmap for potentially greater impact in technology-enabled cancer care coordination. PMID:27332197

    Full Text Available Normal 0 0 2 false false false EN-US JA X-NONE MicrosoftInternetExplorer4 Music use in dementia care often takes place within a music therapy context, where music therapy sessions aim to reduce agitated behaviour, access emotions or enhance inter-personal communication. Such sessions usually take place within care homes and their effect has been evaluated by a number of studies. However, there is little research on music use that takes place outside of care homes (e.g. in community centres for people with dementia who are cared for at home by their family. This paper discusses this type of music use, focusing on the meaning of weekly local music making activities in relation to every day dementia care. I use empirical data from a study of a community based music activity called "Singing for the Brain" (SFTB run by the Alzheimer's Society in the UK. The data was collected through extensive participant observation research and interviews with organisers, carers and care receivers. The preliminary findings from the data analysis are discussed: how SFTB can be seen as a ecological practice; its various “spin-off’ effects in the everyday care of the members with dementia; how SFTB, together with other local music groups, constitute the music and care world in the town; and how this develops into fluid support networks to support local people with dementia and their carers.

    Briones, Janette C.; Handler, Louis M.

    2013-01-01

    Radios today are evolving from awareness toward cognition. A software defined radio (SDR) provides the most capability for integrating autonomic decision making ability and allows the incremental evolution toward a cognitive radio. This cognitive radio technology will impact NASA space communications in areas such as spectrum utilization, interoperability, network operations, and radio resource management over a wide range of operating conditions. NASAs cognitive radio will build upon the infrastructure being developed by Space Telecommunication Radio System (STRS) SDR technology. This paper explores the feasibility of inserting cognitive capabilities in the NASA STRS architecture and the interfaces between the cognitive engine and the STRS radio. The STRS architecture defines methods that can inform the cognitive engine about the radio environment so that the cognitive engine can learn autonomously from experience, and take appropriate actions to adapt the radio operating characteristics and optimize performance.

    Full Text Available Aim: Political decisions usually emerge from the competing interests of politicians, voters, and special interest groups. We investigated the applicability of an advanced methodological concept to determine whether certain institutional positions in a cooperating network have influence on the decision-making procedures. To that end, we made use of the institutional network of relevant health care and health governance institutions, concentrated in Belgrade, Serbia. Methods: We used a Principal Component Analysis (PCA based on a combination of measures for centrality in order to evaluate the positions of 25 players in Belgrade‟s institutional network. Their directed links were determined by a simulated position approach employing the authors‟ long-term involvement. Software packages used consisted of Visone 2.9, UCINET 6, and KeyPlayer 1.44. Results: In our analysis, the network density score in Belgrade was 71%. The PCA revealed two dimensions: control and attractiveness. The Ministry of Health exerted the highest level of control but displayed a low attractiveness in terms of receiving links from important players. The National Health Insurance Fund had less control capacity but a high attractiveness. The National Institute of Public Health‟s position was characterized by a low control capacity and high attractiveness, whereas the National Drug Agency, the National Health Council, and Non-Governmental Organisations were no prominent players. Conclusions: The advanced methodologies used here to analyse the health care policy network in Belgrade provided consistent results indicating that the intended decentralization of the health care network in Belgrade may be incomplete, still with low participation of civil society representatives. With the present study we set the stage for a broad-range survey based data collection applying the methodology piloted in Belgrade.

    American health care organizations are experiencing increasing change driven by emerging partnerships, market demographics, population health initiatives, and merger and acquisition trends. The health care business environment necessitates alterations in how companies operate on a larger scale. New regional leadership roles are being created to provide leadership to systematize networks, build market share, and strengthen market needs. It is important and necessary to explore, review, and contrast the roles, skills, and behaviors of regional leader's roles and the solo organization leaders. It is also imperative to review the benefits of new affiliations for the community and hospital entity. PMID:27584890

    Booth, Mark; Hill, Graham; Moore, Michael J; Dalla, Danielle; Moore, Michael G; Messenger, Anne

    2016-01-01

    On 1 July 2015, the Australian Government established 31 new Primary Health Networks (PHNs), following a review by its former Chief Medical Officer, John Horvath, of 61 Medicare Locals created under the previous Labor administration. The Horvath review recommended, among other things, that new, larger primary health organisations be established to reduce fragmentation of care by integrating and coordinating health services, supporting the role of general practice, and leveraging and administering health program funding. The two main objectives of the new PHNs, as stated on the Department of Health's website, are "increasing the efficiency and effectiveness of medical services for patients, particularly those at risk of poor health outcomes, and improving coordination of care to ensure patients receive the right care in the right place at the right time". Below are three viewpoints, commissioned for this primary health care themed issue of Public Health Research & Practice, from the Australian Government Department of Health, the Public Health Association of Australia and a Sydney-based PHN. We asked the authors to focus particularly on how the newly established networks might help to integrate public health within the primary health care landscape. Our authors have pointed out the huge overlap between public health and primary care and looked at evidence showing the great benefits for health systems of collaboration between the two. Challenges ahead include a possible government focus on delivery of 'frontline' medical services, which may come at the expense of population health, and the complexity of dealing with all primary health care stakeholders, including health professionals, Local Health Districts, nongovernment organisations, research institutions and local communities.

  12. A Novel Intrusion Detection System for Wireless Body Area Network in Health Care Monitoring

    Directory of Open Access Journals (Sweden)

    T. V.P. Sundararajan

    2010-01-01

    Full Text Available Problem statement: Health monitoring, telemedicine, military, interactive entertainment and portable audio/video systems were most promising applications where WBANs can be used. However, designers of such systems face a number of challenging tasks, as they need to address often quite conflicting requirements for size, operating time, precision and reliability. Network security is very important in Wireless Body Area Network (WBAN since the vital human life might be jeopardized, unless managed properly. Approach: This article presented security architecture of a wireless body area network for ambulatory health status monitoring. A novel Intrusion Detection System (IDS inspired by the biological immune system that use Negative Selection Algorithm (NSA was proposed to enhance the performance of Wireless Body Area Networks (WBAN to operate despite the presence of compromised (misbehaving nodes. Results: The proposed IDS scheme had been implemented using network simulator Qualnet v5.2. The performances of IDS scheme had been analyzed using AODV, DSR and DSDV routing protocols for parameters such as average detection rate and false alarm rate. These negative selection detectors are capable of distinguishing well behaving nodes from compromised nodes with good degree of accuracy. The high false positives rate is also minimized. Conclusion/Recommendations: Wireless Body Area Networks are an enabling technology for mobile health care. The IDS can be implemented on today’s devices as it only requires minimal and low-cost hardware changes. The authors strongly believe that adding sufficient security mechanisms to WBAN will study as a trigger in the acceptance of this technology for health care purposes. Simulation results indicate the non-degradability of network performance when these IDS is incorporated in the routing algorithm for security enhancements.

    Changing demographics and an increasing burden of multiple chronic comorbidities in western countries dictate refocusing of heart failure (HF) services from acute in-hospital care to better support the long inter-critical out-of-hospital phases of HF. The needs of the HF population are not adequately addressed by current HF outpatient services, as documented by differences in age, gender, comorbidities and recommended therapies between patients discharged for hospitalized HF and those followed up at HF clinics.The Working Group on Heart Failure of the Italian Association of Hospital Cardiologists (ANMCO) has drafted a consensus document for the organization of a national HF care network. The aims of this document are to describe tasks and requirements of the different health system points of contact for HF patients, and to define how diagnosis, management and care processes should be documented and shared among healthcare professionals. In this document, HF clinics are classified into three groups: 1) community HF clinics, devoted to the management of stable patients in strict liaison with primary care, regular re-evaluation of emerging clinical needs and prompt treatment of impending destabilizations, 2) hospital HF clinics, that target both new-onset and chronic HF patients for diagnostic assessment, treatment planning and early post-discharge follow-up. They act as main referral for medicine units and community clinics; 3) advanced HF clinics, directed at patients with severe disease or persistent clinical instability, candidates to advanced treatment options such as heart transplant or mechanical circulatory support. These different types of HF clinics are integrated in a dedicated network for the management of HF patients on a regional basis, according to geographic features. By sharing predefined protocols and communication systems, these HF networks integrate multiprofessional providers to ensure continuity of care. This consensus document is expected to

    Maillé, Patrick; Naldi, Maurizio; Tuffin, Bruno

    Modeling the competition among telecommunication operators (or providers) as a repeated game may explain why tacit collusion to maintain high charging prices can be observed. Such outcomes clearly do not benefit the users, nor do they provide operators with incentives to improve the network quality of service to outperform their competitors. We propose a simple regulation based on price stability over time, to modify the game played by operators in a way that could prevent collusion.

    Kumar, A.A.; Li, J.; Zhang, M.F. [Prairie View A& M Univ., Texas (United States)

    1994-12-31

    The purpose of this paper is twofold: to discuss high temperature superconductors with specific reference to their employment in telecommunications applications; and to discuss a few of the limitations of the normally employed two-fluid model. While the debate on the actual usage of high temperature superconductors in the design of electronic and telecommunications devices-obvious advantages versus practical difficulties-needs to be settled in the near future, it is of great interest to investigate the parameters and the assumptions that will be employed in such designs. This paper deals with the issue of providing the microwave design engineer with performance data for such superconducting waveguides. The values of conductivity and surface resistance, which are the primary determining factors of a waveguide performance, are computed based on the two-fluid model. A comparison between two models-a theoretical one in terms of microscopic parameters (termed Model A) and an experimental fit in terms of macroscopic parameters (termed Model B)-shows the limitations and the resulting ambiguities of the two-fluid model at high frequencies and at temperatures close to the transition temperature. The validity of the two-fluid model is then discussed. Our preliminary results show that the electrical transport description in the normal and superconducting phases as they are formulated in the two-fluid model needs to be modified to incorporate the new and special features of high temperature superconductors. Parameters describing the waveguide performance-conductivity, surface resistance and attenuation constant-will be computed. Potential applications in communications networks and large scale integrated circuits will be discussed. Some of the ongoing work will be reported. In particular, a brief proposal is made to investigate of the effects of electromagnetic interference and the concomitant notion of electromagnetic compatibility (EMI/EMC) of high T{sub c} superconductors.

    Full Text Available Guaranteed selected quality of telecommunication service and wide area coverage are typical requirements of the ITS (Intelligent Transport Systems applications. Extensive range of wireless data services with reasonable coverage is provided by public wireless services operators, however, mostly no guaranteed relevant range of quality and security is available. ITS services require cost-effectively solution which can be resolved by combination of the "core" public solution with the other public as well as private services where and when it is needed. Such approach requires implementation of the relevant flexible system architecture supported by the efficient decision processes. ITS specific service security requirements would not underestimated, as well. Special situation is identified in case of the C2I (Car to Infrastructure and C2C (Car to Car communication namely if the vehicle on board unit is interconnected with the vehicle CAN (Controlled Area Network based network. Such configurations significantly increase potential of dangerous intruders´ attacks. Probability of the critical hazards appearances grows if the ITS data are accessible in the wide area networks. That is also the main reason why relevant telecommunications security support is understood as one of the crucial part of the ITS telecommunications solution.

    2015-12-01

    Full Text Available Background: Community care workers (CCWs in rural South Africa provide medical, personal, household, educational, and social care services to their clients. However, little understanding exists on how provision of services is approached within a household, taking into account available social support networks. Objective: The aim of this study was to generate an understanding of the processes that underpin the provision of care by CCWs in rural households and their engagement with clients, primary caregivers (PCGs, and other members of the social support network. Design: We analysed in-depth interviews conducted in a triad of participants involved in a home-based care (HBC encounter – 32 clients, 32 PCGs, and 17 CCWs. For each triad, a purposefully selected CCW was linked with a purposefully selected client and the corresponding PCG using maximum variation sampling. Three coders used an inductive content analysis method to describe participants’ references to the nuances of processes followed by CCWs in servicing HBC clients. Written informed consent was obtained from all participants. Findings: The results suggest that, by intuition and prior knowledge, CCWs treated each household uniquely, depending on the clients’ care needs, cooperation, availability of a social network, and the reliability and resilience of the social support system for the client. Four distinct processes took place in rural households: needs assessment for care, rationing of care, appraisal of care, and reinforcement of a social support system. However, there was no particular order or sequence established for these processes, and caregivers followed no prescribed or shared standards. Conclusions: CCWs bring a basket of services to a household, but engage in a constant, dynamic, and cyclical process of weighing needs against services provided. The service package is uniquely crafted and tailored for each household, depending on the absorptive capacity of the social

    Converting the health care delivery system into a learning organization is a key strategy for improving health outcomes. Although the collaborative learning organization approach has been successful in neonatal intensive care units and disease-specific collaboratives, there are few examples in general medicine and none in adult medicine that have leveraged the role of hospitalists nationally across multiple institutions to implement improvements. The authors describe the rationale for and early work of the Hospital Medicine Reengineering Network (HOMERuN), a collaborative of hospitals, hospitalists, and multidisciplinary care teams founded in 2011 that seeks to measure, benchmark, and improve the efficiency, quality, and outcomes of care in the hospital and afterwards. Robust and timely evaluation, with learning and refinement of approaches across institutions, should accelerate improvement efforts. The authors review HOMERuN's collaborative model, which focuses on a community-based participatory approach modified to include hospital-based staff as well as the larger community. HOMERuN's initial project is described, focusing on care transition measurement using perspectives from the patient, caregiver, and providers. Next steps and sustainability of the organization are discussed, including benchmarking, collaboration, and effective dissemination of best practices to stakeholders. PMID:24448050

    Full Text Available Abstract Background Day care-associated infectious diseases are widely recognized as a public health problem but rarely studied. Insights into their dynamics and their association with the day care setting are important for effective decision making in management of infectious disease control. This paper describes the purpose, design and potential of our national multi-center, day care-based sentinel surveillance network for infectious diseases (the KIzSS network. The aim of the KIzSS network is to acquire a long-term insight into the syndromic and microbiological aspects of day care-related infectious diseases and associated disease burden and to model these aspects with day care setting characteristics. Methods/design The KIzSS network applies a prospective cohort design, following day care centers rather than individual children or staff members over time. Data on infectious disease symptoms and related morbidity (children and staff, medical consumption, absenteeism and circulating enteric pathogens (children are collected on a daily, weekly or monthly basis. Every two years, a survey is performed to assess the characteristics of participating day care centers. Discussion The KIzSS network offers a unique potential to study infectious disease dynamics in the day care setting over a sustained period of time. The created (biodatabases will help us to assess day care-related disease burden of infectious diseases among attending children and staff and their relation with the day care setting. This will support the much needed development of evidence-based and pragmatic guidelines for infectious disease control in day care centers.

  17. A queueing network model to analyze the impact of parallelization of care on patient cycle time.

    Science.gov (United States)

    Jiang, Lixiang; Giachetti, Ronald E

    2008-09-01

    The total time a patient spends in an outpatient facility, called the patient cycle time, is a major contributor to overall patient satisfaction. A frequently recommended strategy to reduce the total time is to perform some activities in parallel thereby shortening patient cycle time. To analyze patient cycle time this paper extends and improves upon existing multi-class open queueing network model (MOQN) so that the patient flow in an urgent care center can be modeled. Results of the model are analyzed using data from an urgent care center contemplating greater parallelization of patient care activities. The results indicate that parallelization can reduce the cycle time for those patient classes which require more than one diagnostic and/ or treatment intervention. However, for many patient classes there would be little if any improvement, indicating the importance of tools to analyze business process reengineering rules. The paper makes contributions by implementing an approximation for fork/join queues in the network and by improving the approximation for multiple server queues in both low traffic and high traffic conditions. We demonstrate the accuracy of the MOQN results through comparisons to simulation results. PMID:18826003

    2011-05-01

    Full Text Available Because of its severity, frequency and increasing social and economic impact, Diabetes Mellitus (DM is considered the third priority health problem in the world. Although to date there is no curative treatment, it does have effective measures to reduce its occurrence and limit its complications. Objective: to describe the control program of diabetes in a statewide network of health services in regard to clinical variables, the epidemiology of population served and the control actions, in order to identify strategies for improvement. Methodology: operational research based on secondary data. We reviewed the general conditions of operation of the program based on records of patient care. We studied a random sample of medical records of patients served by the control program of diabetes care units in the network.The results were validated in a meeting with officials of the institution. Results: we detected flaws and points of improvement in the performance of the control program that resulted in specific recommendations for the institutional network. Other failures are due to rules that hinder health system monitoring and control of the DM at the first level. Conclusion:the review of medical records reveals important problems about registration, monitoring and control of diabetics. Other regulatory and contractual provisions of the colombian health system were identified as restrictions that prevent the program to control hyperglycemia and early detection of renal damage. These restrictions could be affecting the programs of control of diabetes in other institutions of the country that are subject to the same rules

  6. The current situation and future scope of radiation emergency medical care network in Nagasaki

    International Nuclear Information System (INIS)

    Under the framework of the International Consortium for Medical Care of Hibakusha and Radiation Life Science (Nagasaki University 21st Century COE Program) and bearing in mind the unique history and responsibility of Nagasaki University, several projects on radiation emergency preparedness are in progress. The critical accident in Tokaimura, Japan in 1999 made us realize that nuclear emergencies happen anywhere radionuclides exist. In fact, nuclear accidents possibly take place in factories, research facilities, hospital and wherever radioactive materials are in transit. Therefore, it is necessary to establish an effective preparedness network system for potential radiation emergency that may occur in Nagasaki and nearby prefectures and to cooperate with other Japanese and worldwide networks.

  10. Integrated optical devices for telecommunications

    Science.gov (United States)

    Qi, Xiaoyuan

    Integrated optical devices have received a lot of interest in recent years. With electronic devices becoming smaller and smaller, semiconductor industries are facing significantly difficult problems. Photonic devices have unique characteristics which can avoid problems in electronic devices and they can achieve better performance. However, the development of integrated optical devices is needed to realize integrated optical circuits in the future. In this thesis, three aspects of integrated optical devices were studied for telecommunication applications. First, integrated isolators were fabricated. Dry etching and wet etching recipes have been developed for the well-known isolator material, yttrium iron garnet (Y3Fe5O 12), and ridge waveguides were patterned into YIG with different configurations. Integrated polarizers based on 2-D YIG photonic crystals (PCs) were also fabricated using a Focused Ion Beam (FIB). Second, an inexpensive method to fabricate 2-D PCs was developed using anodized aluminum oxide (AAO) as an etch mask. An approach to grow nanopores on top of various films/substrates was found. This approach involved growing aluminum films directly onto the substrate of choice, and then anodizing the film electrochemically. The next step was to use reactive ion etching (RIE) to transfer the newly obtained AAO pattern to the underlying films/substrates, and so make PCs, for example in ordered porous Si. The third project was to simulate 1-D and 2-D tunable electro-optic filters for telecommunications. Interfering thin-film structures were studied with Pb(Mg1/3Nb1/3)O3-PbTiO3(PMN-PT) as a 1-D tunable electro-optic layer. Design rules were developed and the performance of these filters was compared with the requirements in dense wavelength division multiplexing (DWDM). 2-D tunable electro-optic filters were also designed based on 2-D photonic crystals and Fabry-Perot structures. The design flow was demonstrated and some results were elaborated. These three

    2012-05-01

    Full Text Available Abstract Background Inequalities in geographic access to health care result from the configuration of facilities, population distribution, and the transportation infrastructure. In recent accessibility studies, the traditional distance measure (Euclidean has been replaced with more plausible measures such as travel distance or time. Both network and raster-based methods are often utilized for estimating travel time in a Geographic Information System. Therefore, exploring the differences in the underlying data models and associated methods and their impact on geographic accessibility estimates is warranted. Methods We examine the assumptions present in population-based travel time models. Conceptual and practical differences between raster and network data models are reviewed, along with methodological implications for service area estimates. Our case study investigates Limited Access Areas defined by Michigan’s Certificate of Need (CON Program. Geographic accessibility is calculated by identifying the number of people residing more than 30 minutes from an acute care hospital. Both network and raster-based methods are implemented and their results are compared. We also examine sensitivity to changes in travel speed settings and population assignment. Results In both methods, the areas identified as having limited accessibility were similar in their location, configuration, and shape. However, the number of people identified as having limited accessibility varied substantially between methods. Over all permutations, the raster-based method identified more area and people with limited accessibility. The raster-based method was more sensitive to travel speed settings, while the network-based method was more sensitive to the specific population assignment method employed in Michigan. Conclusions Differences between the underlying data models help to explain the variation in results between raster and network-based methods. Considering that the

    2011-05-01

    Full Text Available Abstract Background Increasing the effective targeting and promotion of self-care support for long-term conditions requires more of a focus on patient contexts and networks. The aim of this paper is to describe how within a programme of research and implementation, social networks are viewed as being centrally involved in the mobilisation and deployment of resources in the management of a chronic condition. This forms the basis of a novel approach to understanding, designing, and implementing new forms of self-management support. Methods Drawing on evidence syntheses about social networks and capital and the role of information in self-management, we build on four conceptual approaches to inform the design of our research on the implementation of self-care support for people with long-term conditions. Our approach takes into consideration the form and content of social networks, notions of chronic illness work, normalisation process theory (NPT, and the whole systems informing self-management engagement (WISE approach to self-care support. Discussion The translation and implementation of a self-care agenda in contemporary health and social context needs to acknowledge and incorporate the resources and networks operating in patients' domestic and social environments and everyday lives. The latter compliments the focus on healthcare settings for developing and delivering self-care support by viewing communities and networks, as well as people suffering from long-term conditions, as a key means of support for managing long-term conditions. By focusing on patient work and social-network provision, our aim is to open up a second frontier in implementation research, to translate knowledge into better chronic illness management, and to shift the emphasis towards support that takes place outside formal health services.

  13. Solar energy applications in telecommunications

    Science.gov (United States)

    Girard, J.

    The results of a half-decade of a coupled wind-photovoltaic powered, remotely sited telecommunications installation called 'Aerosolec' are reported. A station is examined which was situated at 500 m altitude between Nice and Monaco and comprised a 4 module solar cell plant generating 180 W, a 300 W windpowered generator, and a battery bank. The batteries were linked by a diode, charged by the photovoltaics only when load was met, and provided voltage when the wind/solar cell configuration failed to produce enough power to meet demand. Output of the generators and meteorological parameters were recorded for two years. The station drew a nominal 180W, which was met by the power systems, and involved an actual extra discharge of excess energy. Other, similar stations are outlined, and the use of coupled wind/solar systems for telephone service in remote sites, for optic fiber repeaters, and for telephone relay station are recommended. Cost advantages are seen with the solar/wind systems over liquid hydrocarbon fueled generator systems for low power demand installations.

    The telecommunications sector plays a pivotal role in the system of increasingly connected and interdependent networks that make up national infrastructure. An assessment of the probable structure and function of the bit-moving industry in the twenty-first century must include issues associated with the surety of telecommunications. The term surety, as used here, means confidence in the acceptable behavior of a system in both intended and unintended circumstances. This paper outlines various engineering approaches to surety in systems, generally, and in the telecommunications infrastructure, specifically. It uses the experience and expectations of the telecommunications system of the US as an example of the global challenges. The paper examines the principal factors underlying the change to more distributed systems in this sector, assesses surety issues associated with these changes, and suggests several possible strategies for mitigation. It also studies the ramifications of what could happen if this sector became a target for those seeking to compromise a nation`s security and economic well being. Experts in this area generally agree that the U. S. telecommunications sector will eventually respond in a way that meets market demands for surety. Questions remain open, however, about confidence in the telecommunications sector and the nation`s infrastructure during unintended circumstances--such as those posed by information warfare or by cascading software failures. Resolution of these questions is complicated by the lack of clear accountability of the private and the public sectors for the surety of telecommunications.

    Morishima, Atsutomo; Kijima, Yasuaki

    2012-12-01

    In hospitals, information technology(IT)has been a natural part of care for some time. However, IT has not yet been widely introduced into home care. While performing home care, healthcare providers must carry numerous patients' medical records, and are unable to share the information included in those records with other providers. Thus, we introduced the system of sharing patient information using iPads. This system enables access to patient information regardless of time and place. In addition, we can share information such as X-ray images and computed tomography(CT)scans between different clinics. Thus, we are able to give clearer instructions to patients and other providers in a smoother way. This system could be used to construct a network for home care. In the future, we could aim to share patient information within a much wider network, including families and other kinds of organizations, for optimal care. This system will aid in the development of IT use in home care. PMID:23268884

  14. A Survey of System Architecture Requirements for Health Care-Based Wireless Sensor Networks

    Directory of Open Access Journals (Sweden)

    Abraham O. Fapojuwo

    2011-05-01

    Full Text Available Wireless Sensor Networks (WSNs have emerged as a viable technology for a vast number of applications, including health care applications. To best support these health care applications, WSN technology can be adopted for the design of practical Health Care WSNs (HCWSNs that support the key system architecture requirements of reliable communication, node mobility support, multicast technology, energy efficiency, and the timely delivery of data. Work in the literature mostly focuses on the physical design of the HCWSNs (e.g., wearable sensors, in vivo embedded sensors, et cetera. However, work towards enhancing the communication layers (i.e., routing, medium access control, et cetera to improve HCWSN performance is largely lacking. In this paper, the information gleaned from an extensive literature survey is shared in an effort to fortify the knowledge base for the communication aspect of HCWSNs. We highlight the major currently existing prototype HCWSNs and also provide the details of their routing protocol characteristics. We also explore the current state of the art in medium access control (MAC protocols for WSNs, for the purpose of seeking an energy efficient solution that is robust to mobility and delivers data in a timely fashion. Furthermore, we review a number of reliable transport layer protocols, including a network coding based protocol from the literature, that are potentially suitable for delivering end-to-end reliability of data transmitted in HCWSNs. We identify the advantages and disadvantages of the reviewed MAC, routing, and transport layer protocols as they pertain to the design and implementation of a HCWSN. The findings from this literature survey will serve as a useful foundation for designing a reliable HCWSN and also contribute to the development and evaluation of protocols for improving the performance of future HCWSNs. Open issues that required further investigations are highlighted.

  15. [Dental care in cross-cultural networks-- case management--approaches in group prevention].

    Science.gov (United States)

    Robke, F J

    2000-01-01

    Oral epidemiology studies of previous years have shown an increasing difference in caries cases in respect of different social strata. Thus, frequency of caries cases is related to social status. High rates of caries prevalence are found especially among children from typical areas of welfare problems. Already, today every fifth child is born into a family of immigrants. In areas of typical social deprivation their share is about 40% and more. Since the previous educational campaigns for social fringe groups have hardly shown any positive effect on dental health, new strategies are necessary. In a community of Hanover with low socio-economic status and a generally high caries level, the treatment strategies of dental care for the young have centred on the case-management approaches of social welfare programmes since the early 90s. Beside the expanded basic preventive programme, which includes application of a fluoride varnish for children, social compensatory measures with intercultural networks are also being taken. This concept shows very clearly that the dental health of children living in areas of social disorganisation can be effectively improved by means of these strategies. For the future, dental care for these children requires more intercultural competence and more knowledge of social welfare work by adolescent dental care providers. PMID:11037670

    The Imaging Science and Information Systems (ISIS) Center of the Department of Radiology at Georgetown University Medical Center recently collaborated with the US Army in developing an off-the-shelf teleradiology network for Operation Joint Endeavor, the peace-keeping mission in Bosnia-Herzegovina. The network is part of Operation Primetime III, a project to deploy advanced communications and medical equipment to provide state-of-the-art medical care to the 20,000 US troops stationed there. The network encompasses three major sites: the 212th Mobile Army Surgical Hospital (MASH) near Tuzla, Bosnia-Herzegovina; the 67th Combat Support Hospital (CSH) in Taszar, Hungary; and the Landstuhl Regional Medical Center (LRMC) in Landstuhl, Germany. Planning for the project began in January 1996, and all three sites were operational by April 1996. Since the system was deployed, computed radiography (CR) has been sued almost exclusively at the MASH and CSH for all general x-ray exams. From mid- May to September 1996, over 2700 CR images were acquired at the MASH and over 1600 at the CSH. Since there was not a radiologist a the MASH, the images were transferred to the CSH for primary diagnosis and archiving. In the same time period, over 550 patient folders were sent from the MASH to the CSH.

    Research on service needs among older adults rarely addresses the special circumstances of lesbian, gay, bisexual, and transgender (LGBT) individuals, such as their reliance on friend-centered social networks or the experience of discrimination from service providers. Limited data suggests that older LGBT adults underutilize health and social services that are important in maintaining independence and quality of life. This study explored the social care networks of this population using a mixed-methods approach. Data were obtained from 210 LGBT older adults. The average age was 60 years, and 71% were men, 24% were women, and 5% were transgender or intersex. One-third was Black, and 62% were Caucasian. Quantitative assessments found high levels of morbidity and friend-centered support networks. Need for and use of services was frequently reported. Content analysis revealed unmet needs for basic supports, including housing, economic supports, and help with entitlements. Limited opportunities for socialization were strongly expressed, particularly among older lesbians. Implications for senior programs and policies are discussed. PMID:24313252

    Present-day advanced technologies heavily rely on the exciting magnetic and spectroscopic properties of lanthanide ions. In particular, their ability to generate well-characterized and intense near-infrared (NIR) luminescence is exploited in any modern fiber-optic telecommunication network. In this feature article, we first summarize the whereabouts underlying the design of highly luminescent NIR molecular edifices and materials. We then focus on describing the main trends in three applications related to this spectral range: telecommunications, biosciences, and solar energy conversion. In telecommunications, efforts concentrate presently on getting easily processable polymer-based waveguide amplifiers. Upconversion nanophosphors emitting in the visible after NIR excitation are now ubiquitous in many bioanalyses while their application to bio-imaging is still in its early stages; however, highly sensitive NIR-NIR systems start to be at hand for both in vitro and in vivo imaging, as well as dual probes combining magnetic resonance and optical imaging. Finally, both silicon-based and dye-sensitized solar cells benefit from the downconversion and upconversion capabilities of lanthanide ions to harvest UV and NIR solar light and to boost the overall quantum efficiency of these next-generation devices.

    Full Text Available The field of data mining has flourished into research area of significant technological and social importance due to the advancement in technology. Mining frequent pattern or itemset from real data environment is a fundamental and essential problem in many data mining applications. The Apriori-inspired algorithms show good performance with sparse datasets such as market-basket data, where the frequent patterns are very short. However, in the area with dense datasets such as telecommunication, computational biology and census data, the performance of these algorithms degrades incredibly as there were many, long frequent patterns. The focus of this paper is to design a CPU- efficient algorithm CIMTEL for finding closed frequent calling patterns (long pattern in a telecommunication database. Due to the evaluation of next generation telecommunication network the amount of communication data’s rises in volume, vaiety and velocity (Bid Data. Thus algorithm provides an way for analysis the consumer for service provider. The Performance of this algorithm outperforms the former COLTEL , CHARM and EXPEDITE algorithm by an order of two for a worst case scenario. Also the performance analysis of this algorithm with former algorithms is determined.

    In view of the rapid rate of development of domestic telecommunication services and the emphasis on private networks, it was sought to determine if hospitals had major requirements which could be aggregated and served by such networks. The value of the information transfer services judged to be most promising over the next twenty years was evaluated, based on expenditures and activity levels in five hospitals and one management services firm and the judgement of their senior staff. An implicit assumption is that services will become affordable once the hospital industry aggregates its requirements. A methodology to evaluate the value of telecommunication services in a hospital was developed and tested.

    The liberalisation of network based industries represents an economic problem, which raises on the one hand a multiplicity of theoretically unresolved questions and for which exist now on the other hand experiences in economic policy in Germany. The causes of the economic problems are not only to be found thereby in certain industry characteristics of the network based industries, but also in a missed special treatment of the network based economic sectors in the past by the economic policy. However, competition pushes in network based industries at borders, because the infrastructure necessary for the production of network based services typically represents an non-open to attack, natural monopoly in the hand of an established, vertically integrated supplier. From it extensive possibilities for the discrimination of competitors result, the competition political action need draw. It applies to analyze these in the available work and to discuss alternative solutions of the discrimination problem. (orig.)

    2010-06-01

    Full Text Available Abstract Background Social networks are theorized as significant influences in the innovation adoption and behavior change processes. Our understanding of how social networks operate within healthcare settings is limited. As a result, our ability to design optimal interventions that employ social networks as a method of fostering planned behavior change is also limited. Through this proposed project, we expect to contribute new knowledge about factors influencing uptake of knowledge translation interventions. Objectives Our specific aims include: To collect social network data among staff in two long-term care (LTC facilities; to characterize social networks in these units; and to describe how social networks influence uptake and use of feedback reports. Methods and design In this prospective study, we will collect data on social networks in nursing units in two LTC facilities, and use social network analysis techniques to characterize and describe the networks. These data will be combined with data from a funded project to explore the impact of social networks on uptake and use of feedback reports. In this parent study, feedback reports using standardized resident assessment data are distributed on a monthly basis. Surveys are administered to assess report uptake. In the proposed project, we will collect data on social networks, analyzing the data using graphical and quantitative techniques. We will combine the social network data with survey data to assess the influence of social networks on uptake of feedback reports. Discussion This study will contribute to understanding mechanisms for knowledge sharing among staff on units to permit more efficient and effective intervention design. A growing number of studies in the social network literature suggest that social networks can be studied not only as influences on knowledge translation, but also as possible mechanisms for fostering knowledge translation. This study will contribute to building

    As the enterprise of the “Internet of Things” is rapidly gaining widespread acceptance, sensors are being deployed in an unrestrained manner around the world to make efficient use of this new technological evolution. A recent survey has shown that sensor deployments over the past decade have increased significantly and has predicted an upsurge in the future growth rate. In health-care services, for instance, sensors are used as a key technology to enable Internet of Things oriented health-care monitoring systems. In this paper, we have proposed a two-stage fundamental approach to facilitate the implementation of such a system. In the first stage, sensors promptly gather together the particle measurements of an android application. Then, in the second stage, the collected data are sent over a Femto-LTE network following a new scheduling technique. The proposed scheduling strategy is used to send the data according to the application’s priority. The efficiency of the proposed technique is demonstrated by comparing it with that of well-known algorithms, namely, proportional fairness and exponential proportional fairness. PMID:27152423

    Health care data holds great promise to be used in clinical decision support systems. However, frequent near-synonymous diagnoses recorded separately, as well as the sheer magnitude and complexity of the disease data makes it challenging to extract non-trivial conclusions beyond confirmatory associations from such a web of interactions. Here we present a systematic methodology to derive statistically valid conditional development of diseases. To this end we utilize a cohort of 5,512,469 individuals followed over 13 years at inpatient care, including data on disability pension and cause of death. By introducing a causal information fraction measure and taking advantage of the composite structure in the ICD codes, we extract an effective directed lower dimensional network representation (100 nodes and 130 edges) of our cohort. Unpacking composite nodes into bipartite graphs retrieves, for example, that individuals with behavioral disorders are more likely to be followed by prescription drug poisoning episodes, whereas women with leiomyoma were more likely to subsequently experience endometriosis. The conditional disease development represent putative causal relations, indicating possible novel clinical relationships and pathophysiological associations that have not been explored yet.

    2014-12-01

    Full Text Available Using three spatial network measures of “space syntax”, this correlational study describes four interaction-related behaviors among three groups of users in relation to visibility and accessibility of spaces in four adult intensive care units (ICUs of different size, geometry, and specialty. Systematic field observations of interaction-related behaviors show significant differences in spatial distribution of interaction-related behaviors in the ICUs. Despite differences in unit characteristics and interaction-related behaviors, the study finds that when nurses and physicians “interact while sitting” they prefer spaces that help maintain a high level of environmental awareness; that when nurses “walk” and “interact while walking” they avoid spaces with better global access and visibility; and that everyone in ICUs “walk” more in spaces with higher control over neighboring spaces. It is argued that such consistent behavioral patterns occur due to the structural similarities of spatial networks over and above the more general functional similarities of ICUs.

    Alliance Against Cancer (ACC) was established in Rome in 2002 as a consortium of six Italian comprehensive cancer centers (Founders). The aims of ACC were to promote a network among Italian oncologic institutions in order to develop specific, advanced projects in clinical and translational research. During the following years, many additional full and associate members joined ACC, that presently includes the National Institute of Health, 17 research-oriented hospitals, scientific and patient organizations. Furthermore, in the last three years ACC underwent a reorganization process that redesigned the structure, governance and major activities. The present goal of ACC is to achieve high standards of care across Italy, to implement and harmonize principles of modern personalized and precision medicine, by developing cost effective processes and to provide tailored information to cancer patients. We herein summarize some of the major initiatives that ACC is currently developing to reach its goal, including tumor genetic screening programs, establishment of clinical trial programs for cancer patients treated in Italian cancer centers, facilitate their access to innovative drugs under development, improve quality through an European accreditation process (European Organization of Cancer Institutes), and develop international partnerships. In conclusion, ACC is a growing organization, trying to respond to the need of networking in Italy and may contribute significantly to improve the way we face cancer in Europe. PMID:26578263

    CommAspen is a new agent-based model for simulating the interdependent effects of market decisions and disruptions in the telecommunications infrastructure on other critical infrastructures in the U.S. economy such as banking and finance, and electric power. CommAspen extends and modifies the capabilities of Aspen-EE, an agent-based model previously developed by Sandia National Laboratories to analyze the interdependencies between the electric power system and other critical infrastructures. CommAspen has been tested on a series of scenarios in which the communications network has been disrupted, due to congestion and outages. Analysis of the scenario results indicates that communications networks simulated by the model behave as their counterparts do in the real world. Results also show that the model could be used to analyze the economic impact of communications congestion and outages.

    Full Text Available The challenge in the field of multimedia telecommunications is an attempt to integrate texts, sound, images and videos coherently and consistently and to ensure simplicity and interactivity of operation. In order to make the proposed multimedia applications acceptable to end-users, the quality of transmission through the network and message presentation should have special attention. The main aims of this paper are the introduction to the communication channel with its basic elements, a detailed description of the information source and the presentation of possible approaches to the analysis of the telecommunication channel. Introduction In the age of mass application of various communication means, end-users of telecommunication channel elements rarely pay attention to the processes taking place in everyday communication and the elements presented in the channel. In order to discuss all the factors that influence the establishment and maintenance of the links, this paper will explain the basic elements of telecommunication channels. Source Every object that generates messages to be transferred to a recipient is called the source of the message. Directors, writers, speakers, books, newspapers, various instruments (thermometer, barometer, ammeter, etc., computers, a man himself - these are all sources of various messages. In relation to facilities that generate messages, there are different sources of messages. All the messages that they generate belong to discrete or continuous modes of messages. Discrete messages can be presented with element sets, where elements can be considered through different values of observed messages. Each text message of arbitrary length, for example, is made of a finite number of elements - symbols (letters, numbers, punctuation marks, from the set of symbols called the alphabet message source. Continuous messages can be presented with an infinite number of sets of elements where elements can have different values of

    2016-05-01

    Recent advances in medical treatment and emergency applications, the need of integrating wireless body area network (WBAN) with cloud computing can be motivated by providing useful and real time information about patients' health state to the doctors and emergency staffs. WBAN is a set of body sensors carried by the patient to collect and transmit numerous health items to medical clouds via wireless and public communication channels. Therefore, a cloud-assisted WBAN facilitates response in case of emergency which can save patients' lives. Since the patient's data is sensitive and private, it is important to provide strong security and protection on the patient's medical data over public and insecure communication channels. In this paper, we address the challenge of participant authentication in mobile emergency medical care systems for patients supervision and propose a secure cloud-assisted architecture for accessing and monitoring health items collected by WBAN. For ensuring a high level of security and providing a mutual authentication property, chaotic maps based authentication and key agreement mechanisms are designed according to the concept of Diffie-Hellman key exchange, which depends on the CMBDLP and CMBDHP problems. Security and performance analyses show how the proposed system guaranteed the patient privacy and the system confidentiality of sensitive medical data while preserving the low computation property in medical treatment and remote medical monitoring.

    We validated three single-item measures for emotional exhaustion (EE) and depersonalization (DP) among rural physician/nonphysician practitioners. We linked cross-sectional survey data (on provider demographics, satisfaction, resilience, and burnout) with administrative information from an integrated health care network (1 academic medical center, 6 community hospitals, 31 clinics, and 19 school-based health centers) in an eight-county underserved area of upstate New York. In total, 308 physicians and advanced-practice clinicians completed a self-administered, multi-instrument questionnaire (65.1% response rate). Significant proportions of respondents reported high EE (36.1%) and DP (9.9%). In multivariable linear mixed models, scores on EE/DP subscales of the Maslach Burnout Inventory were regressed on each single-item measure. The Physician Work-Life Study's single-item measure (classifying 32.8% of respondents as burning out/completely burned out) was correlated with EE and DP (Spearman's ρ = .72 and .41, p burnout.

    2013-03-01

    Efforts have been increasingly invested to improve local health systems' capacities in developing countries. We describe the application of innovative methods based on a social network analysis approach. The findings presented refer to a study carried out between July 2008 and January 2010 in the Brong Ahafo region of Ghana. Social network analysis methods were applied in five different districts using the software package Ucinet to calculate the various properties of the social network of eye care providers. The study focused on the managerial decisions made by Ghanaian district hospital managers about the governance of the health system. The study showed that the health system in the Brong Ahafo region experienced significant changes specifically after a key shock, the departure of an international organization. Several other actors at different levels of the network disappeared, the positions of nurses and hospital managers changed, creating new relationships and power balances that resulted in a change in the general structure of the network. The system shifted from a centralized and dense hierarchical network towards an enclaved network composed of five sub-networks. The new structure was less able to respond to shocks, circulate information and knowledge across scales and implement multi-scale solutions than that which it replaced. Although the network became less resilient, it responded better to the management needs of the hospital managers who now had better access to information, even if this information was partial. The change of the network over time also showed the influence of the international organization on generating links and creating connections between actors from different levels. The findings of the study reveal the importance of creating international health connections between actors working in different spatial scales of the health system. PMID:22411882

    The German Telecommunications Satellite (DFS) Program is to provide telecommunications service for high data rate transmission of text and video data to the Federal Republic of Germany within the 11-14 GHz and 20-30 GHz bands. The space segment of this program is composed of three satellites, DFS-1, DFS-2, and DFS-3, which will be located at 23.5 degrees E longitude of the geostationary orbit. The DFS will be launched from the Center Spatial Guyanis in French Giana on an Ariane launch vehicle. The mission follows the typical injection sequence: parking orbit, transfer orbit, and earth orbit. Attitude maneuvers will be performed to orient the spacecraft prior to Apogee Kick Motor (AKM) firing. After AKM firing, drift phase orbital and attitude maneuvers will be performed to place the spacecraft in its final geostationary position. The Deep Space Network (DSN) will support the transfer and drift orbit mission phases. Information is presented in tabular form for the following areas: DSN support, compatibility testing, frequency assignments, telemetry, command, and tracking support responsibilities.

    2015-09-01

    The use of fourth-generation (4G) mobile telecommunications to provide real-time video consultations were investigated in this study with the aims of determining if 4G is a suitable telecommunications technology; and secondly, to identify if variation in perceived audio and video quality were due to underlying network performance. Three patient end-points that used 4G Internet connections were evaluated. Consulting clinicians recorded their perception of audio and video quality using the International Telecommunications Union scales during clinics with these patient end-points. These scores were used to calculate a mean opinion score (MOS). The network performance metrics were obtained for each session and the relationships between these metrics and the session's quality scores were tested. Clinicians scored the quality of 50 hours of video consultations, involving 36 clinic sessions. The MOS for audio was 4.1 ± 0.62 and the MOS for video was 4.4 ± 0.22. Image impairment and effort to listen were also rated favourably. There was no correlation between audio or video quality and the network metrics of packet loss or jitter. These findings suggest that 4G networks are an appropriate telecommunication technology to deliver real-time video consultations. Variations in quality scores observed during this study were not explained by the packet loss and jitter in the underlying network. Before establishing a telemedicine service, the performance of the 4G network should be assessed at the location of the proposed service. This is due to known variability in performance of 4G networks. PMID:25766856

  10. Decentralized production management: telecommunication and coordination schemes validation

    International Nuclear Information System (INIS)

    Decentralized production development is a reality in the majority of the power networks all over the world. The deregulation of the market of energy, ecological constraints as well as the technological developments of small power production encourage this development. Distribution networks represent the portion of the power system where the development of this production is the most awaited. Some studies carried out on the interconnection of decentralized production on a large scale ratio have shown significant effects and impacts on operation of the entire electric system. Indeed, the entire distribution network is going to be deeply modified by the introduction of new functions of remote control, of specific architectures, of intelligent protection systems and of telecommunication and information technologies. With these new paradigms the ability of testing and simulating the Distribution Management Systems is more and more necessary. Also, this is a crucial requirement for new communication means in order to better define the new management strategies of the production units within the distribution networks. The aim of this paper is to present a new real time experimental bench able to validate control strategies and communication devices included in Distribution Management Systems (DMS). (authors)

    2010-01-01

    The Phoenix Lander, first of NASA's Mars Scout missions, arrived at the Red Planet on May 25, 2008. From the moment the lander separated from its interplanetary cruise stage shortly before entry, the spacecraft could no longer communicate directly with Earth, and was instead entirely dependent on UHF relay communications via an international network of orbiting Mars spacecraft, including NASA's 2001 Mars Odyssey (ODY) and Mars Reconnaissance Orbiter (MRO) spacecraft, as well as ESA's Mars Express (MEX) spacecraft. All three orbiters captured critical event telemetry and/or tracking data during Phoenix Entry, Descent and Landing. During the Phoenix surface mission, ODY and MRO provided command and telemetry services, far surpassing the original data return requirements. The availability of MEX as a backup relay asset enhanced the robustness of the surface relay plan. In addition to telecommunications services, Doppler tracking observables acquired on the UHF link yielded an accurate position for the Phoenix landing site.

    2015-10-01

    Full Text Available This paper describes the application of Analytic Hierarchy Process (AHP for unraveling customers’ motivation for churn of telecommunication network in Nigeria. By identifying, modeling and measuring of customers` churn motivations across four mobile telecommunication service providers in Nigeria. AHP was used to design a hierarchical model of seven criteria for customers` churning of network and investigates the relative priorities of the criteria through a pairwise comparison. The questionnaire were administered through convenient sampling to 480 mobile telecommunication customers and was completed and returned by 438 mobile phone subscribers in Lagos state, Nigeria, but only 408 copies were useful for the analysis of this study. The result shows that six out of the seven criteria have weight above 10% in their individual contribution to motivating customer churn behavior in the Nigeria telecommunication industry. The inefficient data/ internet plan criterion has the highest weight of 18.81% relative to the churn decision. Thus, AHP effectively supported modeling and analyzing subscribers` motivation toward good marketing decision for both the individual and the organization. It helps in developing an analytic and intelligible framework of decision-making on complex problem of customer churn in an emerging market like Nigeria

This results in frequent and time-consuming outpatient examinations for the patient and family at the oncological center in order to evaluate clinical condition and hematological findings. In widespread regions such as the Weser-Ems area in northwest Lower Saxony, Germany, the long distances between patients' home and the oncological center lead to higher risks and impairment of quality of life (QoL) for the patients and their families. Accordingly, in 2001 pediatric hospitals and practices, patient care services and patients' support groups in Weser-Ems founded a network (Verbund PädOnko Weser-Ems). The "Verbund PädOnko" aims at coordinated, high-quality regional outpatient patient treatment in order to reduce risks of long-distance transports to reach the oncological center. Since 2005 a newly established mobile care team realized 1 443 home visits covering a total of 150 300 km. Since 2007 the network has been funded by health insurance organisations. Internal and external benchmarking was performed showing that the rate of short term inpatient treatments were reduced. Treatment quality was assured and the QoL of the patients and their families was improved through the work of the network. The "Verbund PädOnko Weser-Ems" network represents a promising prototype model for the regional coordination of outpatient treatment and care of patients with rare diseases in wide spread areas.

    2008-12-01

    Full Text Available The convergence of telecommunication, cable TV, and broadcast networks towards the Internet technology will enable the provision of emerging multimedia services as well as the integration of rich communication capabilities with TV services. However, enabling efficient delivery of interactive personalized multimedia services with mobility support requires an advanced overlay control framework. The IP Multimedia Subsystem (IMS offers the basic functions to manage multimedia sessions over different access networks. This paper outlines current standardization activities that address the provisioning of TV services over IP networks—known as IPTV—and proposes a novel end-to-end overall architecture based on IMS that enables the delivery of converged multimedia services. Furthermore, the paper presents the FOKUS Media Interoperability Lab as a reference implementation of this framework which covers a widespread spectrum of converged interactive scenarios. The final section gives an impression of the system performance by providing the end-to-end signaling delay of a session setup for live TV service delivered over unicast transmission mode.

    Full Text Available This study examines the critical influence of advertising on consumer choice of telecommunication services in Nigeria. The advertisement played a key role in providing the consumers with product information. The study investigates the effect of marketing medium of telecommunication as a proxy for advertisement on preference of telecommunication services as a proxy for consumer choice in Nigeria. The Binary Logit Model (BLM and descriptive analytical frameworks are used to evaluate the statistical importance of advertisement, quality of services, income of the consumer, product’s self and related service charges for a consumer choice of telecommunication services through Wald test. The findings show that product’s self service charge and service quality are statistically significant for a consumer choice of telecommunication services in Nigeria at 1 percent significance level. And, related product’s service is statistically significant for a consumer choice of telecommunication services in Nigeria at 5 percent significance level. While advertisement and income of the consumer are statistically significant for a consumer choice of telecommunication services in Nigeria at 10 percent. The study concludes that advertisement is important for the choice of telecommunication services in Nigeria but having less impact. And, product’s self service charge and service quality are hugely significant for the choice of telecommunication services in Nigeria. Therefore, the sector of telecommunications needs more investment in advertisement so as to have telecommunications’ products information spread in order to stimulate the increase in demand for telecommunication services in Nigeria.

  19. A public-private trauma center network in Florida harnesses data to improve care quality for an aging population.

    Science.gov (United States)

    DuVernay, Christina

    2013-12-01

    As the US population ages, trauma systems face new challenges in addition to the long-standing problem of access. Patients ages sixty-five and older are more likely than younger patients to fall and suffer serious injury or death as a result. This older patient population, when compared with younger cohorts, suffers higher mortality rates, has more comorbidities-diabetes, cancer, and heart conditions being the more serious among them-and takes more medications, which can complicate treatment. The University of South Florida (USF) Medical School and the HCA hospital system have partnered to create a network of five trauma centers in underserved areas of the state to increase access to trauma care for all Floridians while maintaining a special focus on geriatric trauma care. Collecting and analyzing data for improving care quality and undertaking research is a central aim of the partnership. Based on their research findings, trauma surgeons in the USF/HCA Trauma Network have identified best practices and codified them in standard operating procedures. PMID:24301397

  20. Effects of Natural Disaster Trends: A Case Study for Expanding the Pre-Positioning Network of CARE International

    Directory of Open Access Journals (Sweden)

    Serhan Duran

    2012-08-01

    Full Text Available The increasing number of natural disasters in the last decade necessitates the increase in capacity and agility while delivering humanitarian relief. A common logistics strategy used by humanitarian organizations to respond this need is the establishment of pre-positioning warehouse networks. In the pre-positioning strategy, critical relief inventories are located near the regions at which they will be needed in advance of the onset of the disaster. Therefore, pre-positioning reduces the response time by totally or partially eliminating the procurement phase and increasing the availability of relief items just after the disaster strikes. Once the pre-positioning warehouse locations are decided and warehouses on those locations become operational, they will be in use for a long time. Therefore, the chosen locations should be robust enough to enable extensions, and to cope with changing trends in disaster types, locations and magnitudes. In this study, we analyze the effects of natural disaster trends on the expansion plan of pre-positioning warehouse network implemented by CARE International. We utilize a facility location model to identify the additional warehouse location(s for relief items to be stored as an extension of the current warehouse network operated by CARE International, considering changing natural disaster trends observed over the past three decades.

    Full Text Available Abstract The mobile telecommunications industry is capital intensive by nature. With the rapid advancement of technology and changing consumer behaviors mobile network operators has had to adapt their product and service portfolio in quick succession. The main implication of the need for high capital investments is the risk associated with the investment. Therefore it is essential that mobile telcos follow up technological investments with the correct service provisioning to the customers. This requires a thorough understanding of the behavior of the consumers. Through this paper the author attempts to identify evaluate and quantify the effects of a number of traits of consumers that determine the consumer preference to a particular mobile network brand. The author also provides recommendations on strategy formulation. The evaluation has been carried out in the context of the Sri Lankan Mobile Telecommunications Industry.

    Full Text Available Objective. To describe and evaluate the feasibility of integrating a suicide prevention program with Primary Health Care services and evaluate if such system can improve screening and identification of depressive disorder, reduce number of suicide attempters, and lower rate of suicide completion. Methodology. This was a quasi-experimental trial in which one community was exposed to the intervention versus the control community with no such exposure. The study sites were two counties in Western Iran. The intervention protocol called for primary care and suicide prevention collaboration at different levels of care. The outcome variables were the number of suicides committed, the number of documented suicide attempts, and the number of identified depressed cases. Results. We identified a higher prevalence of depressive disorders in the intervention site versus the control site (χ2=14.8, P<0.001. We also found a reduction in the rate of suicide completion in the intervention region compared to the control, but a higher prevalence of suicide attempts in both the intervention and the control sites. Conclusion. Integrating a suicide prevention program with the Primary Health Care network enhanced depression and suicide surveillance capacity and subsequently reduced the number of suicides, especially in rural areas.

  14. The effect of introducing increased-reliability-risk electronic components into 3rd generation telecommunications systems

    International Nuclear Information System (INIS)

    In this paper, the dependability of 3rd generation telecommunications network systems is studied. Special attention is paid to a case where increased-reliability-risk electronic components are introduced to the system. The paper consists of three parts: First, the reliability data of four electronic components is considered. This includes statistical analysis of the reliability test data, thermo-mechanical finite element analysis of the printed wiring board structures, and based on those, a field reliability estimate of the components is constructed. Second, the component level reliability data is introduced into the network element reliability analysis. This is accomplished by using a reliability block diagram technique and Monte Carlo simulation of the network element. The end result of the second part is a reliability estimate of the network element with and without the high-risk component. Third, the whole 3rd generation network having multiple network elements is analyzed. In this part, the criticality of introducing high-risk electronic components into a 3rd generation telecommunications network is considered

    2014-07-01

    The era of big data, loosely defined as the development and analysis of large or complex data sets, brings new opportunities to empower patients and their families to generate, collect, and use their health information for both clinical and research purposes. In 2013 the Patient-Centered Outcomes Research Institute launched a large national research network, PCORnet, that includes both clinical and patient-powered research networks. This article describes these networks, their potential uses, and the challenges they face. The networks are engaging patients, family members, and caregivers in four key ways: contributing data securely, with privacy protected; including diverse and representative groups of patients in research; prioritizing research questions, participating in research, and disseminating results; and participating in the leadership and governance of patient-powered research networks. If technical, regulatory, and organizational challenges can be overcome, PCORnet will allow research to be conducted more efficiently and cost-effectively and results to be disseminated quickly back to patients, clinicians, and delivery systems to improve patient health.

    The rural sector of the US is examined from the point of view of whether telecommunications technology can augment the development of rural education. Migratory farm workers and American Indians were the target groups which were examined as examples of groups with special needs in rural areas. The general rural population and the target groups were examined to identify problems and to ascertain specific educational needs. Educational projects utilizing telecommunications technology in target group settings were discussed. Large scale regional ATS-6 satellite-based experimental educational telecommunications projects were described. Costs and organizational factors were also examined for large scale rural telecommunications projects.

    Full Text Available BackgroundAn interactive web tool has been developed for facilitating shared decision-making in dementia-care networks. The DecideGuide provides a chat function for easier communication between network members, a deciding together function for step-by-step decision-making, and an individual opinion function for eight dementia-related life domains. The aim of this study was to gain insight in the user friendliness of the DecideGuide, user acceptance and satisfaction, and participants’ opinion of the DecideGuide for making decisions.Materials and methodsA 5-month field study included four dementia-care networks (19 participants in total. The data derived from structured interviews, observations, and information that participants logged in the DecideGuide. Structured interviews took place at the start, middle, and end of the field study with people with dementia, informal caregivers, and case managers. Results1. The user friendliness of the chat and individual opinion functions was adequate for case managers and most informal caregivers. Older participants, with or without dementia, had some difficulties using a tablet and the DecideGuide. The deciding together function does not yet provide adequate instructions for all. The user interface needs simplification. 2. User acceptance and satisfaction: everybody liked the chat’s easy communication, handling difficult issues for discussion, and the option of individual opinions. 3. The DecideGuide helped participants structure their thoughts. They felt more involved and shared more information about daily issues than before. ConclusionParticipants found the DecideGuide valuable in decision-making. The chat function seems powerful in helping members engage with one another constructively. Such engagement is a prerequisite for making shared decisions. Regardless of participants’ use of the tool, they saw the DecideGuide's added value.

    Full Text Available The paper will analyze the consumption behaviour of the Orange mobile telephony company’s clients towards its services’ characteristics within the current economic financial crisis, taking into consideration the following elements: the low tariffs (for calls/ subscriptions/ other services, the quality of calls/ of sound, the network coverage within the territory, the company’s reputation, the negotiated offer, the quality and availability of the customer care service, the diversity of the auxiliary services, the range and prices of the mobile telephones, the costs that pay those who make calls towards this network, the loyalty programs, the usage of a last generation technology, the friends have subscriptions in the same network and the promotional offers. For a thorough research we will divide the operator’s clients into natural persons clients and legal persons clients, each group having its specificities. The data gathering method was the questionnaire sent by post office to all the Orange Romania branches (a total of 225 branches. We received a number of 64 responses, what means a responses rate of 28.4%, which were analyzed using the SPSS informatics program focusing on the correlation analysis and factor analysis. The main results emphasize the fact that the fight to attract clients becomes more and more powerful. The very competitive market leads to the growth of the importance of the price in choosing a provider. The operators’ short term gains from the clients that prefer low prices represent a long term risk of image. Choosing some services packages is sometimes very difficult due to the complexity of the offer. The clients expect the service to work, be simple and easy to use. They want to benefit from rapid and efficient assistance if errors occur and the operator respects the clauses of the contract. The results obtained through this study, allowed us to make an opinion on the perspective that the

    McNulty, John C.

    2008-02-01

    Despite the initial skepticism of OEM companies regarding reliability, MEMS-based devices are increasingly common in optical networking. This presentation will discuss the use and reliability of MEMS in a variety of network applications, from tunable lasers and filters to variable optical attenuators and dynamic channel equalizers. The failure mechanisms of these devices will be addressed in terms of reliability physics, packaging methodologies, and process controls. Typical OEM requirements will also be presented, including testing beyond of the scope of Telcordia qualification standards. The key conclusion is that, with sufficiently robust design and manufacturing controls, MEMS-based devices can meet or exceed the demanding reliability requirements for telecommunications components.

    The use of Facebook is ubiquitous among both patients and physicians. Often Facebook intrudes into medical practice, thereby highlighting its potential to be either a positive or negative factor in a patient's medical care. Despite being a "hot topic" in the medical literature, very few real world examples exist of physicians actually using information obtained from Facebook to reach a diagnosis or otherwise affect patient care. We present a case involving a 13-year-old girl who posted photographs and captions on Facebook demonstrating suicidal ideation. The patient's parents were alerted to the girl's statements in her Facebook profile and brought her to the emergency department. The girl's statements and photographs, as reported by her parents, were used by an emergency physician to make a diagnosis of suicidal risk and to disposition of the patient to an inpatient psychiatric ward. We discuss the potential diagnostic utility of information posted on Facebook and briefly discuss the ethical questions surrounding this situation. PMID:24160899

    Full Text Available Abstract Background People with mental disorders have a higher prevalence of physical illnesses and reduced life expectancy as compared with the general population. However, there is a lack of knowledge across Europe concerning interventions that aim at reducing somatic morbidity and excess mortality by promoting behaviour-based and/or environment-based interventions. Methods and design HELPS is an interdisciplinary European network that aims at (i gathering relevant knowledge on physical illness in people with mental illness, (ii identifying health promotion initiatives in European countries that meet country-specific needs, and (iii at identifying best practice across Europe. Criteria for best practice will include evidence on the efficacy of physical health interventions and of their effectiveness in routine care, cost implications and feasibility for adaptation and implementation of interventions across different settings in Europe. HELPS will develop and implement a "physical health promotion toolkit". The toolkit will provide information to empower residents and staff to identify the most relevant risk factors in their specific context and to select the most appropriate action out of a range of defined health promoting interventions. The key methods are (a stakeholder analysis, (b international literature reviews, (c Delphi rounds with experts from participating centres, and (d focus groups with staff and residents of mental health care facilities. Meanwhile a multi-disciplinary network consisting of 15 European countries has been established and took up the work. As one main result of the project they expect that a widespread use of the HELPS toolkit could have a significant positive effect on the physical health status of residents of mental health and social care facilities, as well as to hold resonance for community dwelling people with mental health problems.

    Despite the myriad assistive technologies that have been developed over the years, high installation costs and limited functionalities have prevented their widespread adoption. To overcome these barriers, the concept of body sensor networks (BSNs) was introduced, which proposes the development of miniaturized wireless sensing systems to continuously capture physiological signals and context information. Many novel sensing platforms have since been introduced, enabling pervasive monitoring of blood pressure, Galvanic skin response, electrocardiogram (EKG), gait, photoplethysmogram (PPG), and other vital signs.

    An overview is provided of the Space Exploration Initiative (SEI) concepts for telecommunications, information systems, and navigation (TISN), and engineering and architecture issues are discussed. The SEI program data system is reviewed to identify mission TISN interfaces, and reference TISN concepts are described for nominal, degraded, and mission-critical data services. The infrastructures reviewed include telecommunications for robotics support, autonomous navigation without earth-based support, and information networks for tracking and data acquisition. Four options for TISN support architectures are examined which relate to unique SEI exploration strategies. Detailed support estimates are given for: (1) a manned stay on Mars; (2) permanent lunar and Martian settlements; short-duration missions; and (4) systematic exploration of the moon and Mars.

  1. Laying the Groundwork: Lessons Learned from the Telecommunications Industry for Distributed Generation; Preprint

    Energy Technology Data Exchange (ETDEWEB)

    Wise, A. L.

    2008-05-01

    The telecommunications industry went through growing pains in the past that hold some interesting lessons for the growing distributed generation (DG) industry. The technology shifts and stakeholders involved with the historic market transformation of the telecommunications sector mirror similar factors involved in distributed generation today. An examination of these factors may inform best practices when approaching the conduits necessary to accelerate the shifting of our nation's energy system to cleaner forms of generation and use. From a technical perspective, the telecom industry in the 1990s saw a shift from highly centralized systems that had no capacity for adaptation to highly adaptive, distributed network systems. From a management perspective, the industry shifted from small, private-company structures to big, capital-intensive corporations. This presentation will explore potential correlation and outline the lessons that we can take away from this comparison.

  2. The Case for Deep Space Telecommunications Relay Stations

    Science.gov (United States)

    Chandler, Charles W.; Miranda, Felix A. (Technical Monitor)

    2004-01-01

    Each future mission to Jupiter and beyond must carry the traditional suite of telecommunications systems for command and control and for mission data transmission to earth. The telecommunications hardware includes the large antenna and the high-power transmitters that enable the communications link. Yet future spacecraft will be scaled down from the hallmark missions of Galileo and Cassini to Jupiter and Saturn, respectively. This implies that a higher percentage of the spacecraft weight and power must be dedicated to telecommunications system. The following analysis quantifies this impact to future missions and then explores the merits of an alternative approach using deep space relay stations for the link back to earth. It will be demonstrated that a telecommunications relay satellite would reduce S/C telecommunications weight and power sufficiently to add one to two more instruments.

    Evaluations of multisite community-based projects are notoriously difficult to conceptualize and conduct. Projects may share an overarching vision but operate in varying contexts and pursue different initiatives. One tool that can assist evaluators facing these challenges is to develop a "theory of action" (TOA) that identifies critical assumptions regarding how a program expects to achieve its goals. Community Care Network (CCN) evaluators used the TOA to refine research questions, define key variables, relate questions to each other, and identify when we might realistically expect to observe answers. In this article, the authors present their national-level CCN TOA. They also worked with sites to help them "surface" their local TOA; the article analyzes the results to determine the content, clarity, extent of evidence base, and strategic orientation of theories articulated by different sites.

    Edwards, C.; DePaula, R.

    2010-01-01

    Over the past decade, an evolving network of relay-equipped orbiters has advanced our capabilities for Mars exploration. NASA's Mars Global Surveyor, 2001 Mars Odyssey, and Mars Reconnaissance Orbiter (MRO), as well as ESA's Mars Express Orbiter, have provided telecommunications relay services to the 2003 Mars Exploration Rovers, Spirit and Opportunity, and to the 2007 Phoenix Lander. Based on these successes, a roadmap for continued Mars relay services is in place for the coming decade. MRO and Odyssey will provide key relay support to the 2011 Mars Science Laboratory (MSL) mission, including capture of critical event telemetry during entry, descent, and landing, as well as support for command and telemetry during surface operations, utilizing new capabilities of the Electra relay payload on MRO and the Electra-Lite payload on MSL to allow significant increase in data return relative to earlier missions. Over the remainder of the decade a number of additional orbiter and lander missions are planned, representing new orbital relay service providers and new landed relay users. In this paper we will outline this Mars relay roadmap, quantifying relay performance over time, illustrating planned support scenarios, and identifying key challenges and technology infusion opportunities.

    2011-01-01

    Full Text Available What make a good doctor is a question posed by the public and profession and is key when designing training programmes. The goal of training is to change practice not simply acquire knowledge yet too often curriculums and assessment focuses on knowledge and skills. Professional practice is underpinned by beliefs and values and therefore training may need to challenge deeply held values in order to result in a change in practice. Palliative care offers an opportunity to challenge values at a deeply personal level as it brings experiences of pain and suffering alongside clinical knowledge and skills. Palliative care is holistic and so real scenarios where physical, psychological, social and spiritual issues are evident can be presented in an interactive, learner centered environment. Training in ethics alongside clinical skills will assist the development of judgment which should also be assessed. Communication skills enable the clinician to hear and understand the needs and wishes of those facing life limiting illness. Training should include aspects of modeling and mentorship to demonstrate and integrate the learning with the realities of clinical practice and include those who lead and influence policy and advocacy.

    Full Text Available Customer churn is a focal concern for most of the services based companies which have fixed operating costs. Among various industries which suffer from this issue, telecommunications industry can be considered at the top of the list. In order to counter this problem one must recognize the churners before they churn. This work develops an effective and efficient model which has the ability to predict the future churners for broadband internet services. For this purpose Genetic Programming (GP is employed to evolve a suitable classifier by using the customer based features. Genetic Programming (GP is population based heuristic used to solve complex multimodal optimization problems. It is an evolutionary approach use the Darwinian principle of natural selection (survival of the fittest analogs with various naturally occurring operations, including crossover (sexual recombination, mutation (to randomly perturbed or change the respective gene value and gene duplication. The intelligence induced in the system not only generalizes the model for a variety of real world applications but also make it adaptable for dynamic environment. Comprehensive experimentations are performed in order to validate the effectiveness and robustness of the proposed system. It is clear from the experimental results that the proposed system outperforms other state of the art churn prediction techniques.

  9. Space Telecommunications Radio System (STRS) Compliance Testing

    Science.gov (United States)

    Handler, Louis M.

    2011-01-01

    The Space Telecommunications Radio System (STRS) defines an open architecture for software defined radios. This document describes the testing methodology to aid in determining the degree of compliance to the STRS architecture. Non-compliances are reported to the software and hardware developers as well as the NASA project manager so that any non-compliances may be fixed or waivers issued. Since the software developers may be divided into those that provide the operating environment including the operating system and STRS infrastructure (OE) and those that supply the waveform applications, the tests are divided accordingly. The static tests are also divided by the availability of an automated tool that determines whether the source code and configuration files contain the appropriate items. Thus, there are six separate step-by-step test procedures described as well as the corresponding requirements that they test. The six types of STRS compliance tests are: STRS application automated testing, STRS infrastructure automated testing, STRS infrastructure testing by compiling WFCCN with the infrastructure, STRS configuration file testing, STRS application manual code testing, and STRS infrastructure manual code testing. Examples of the input and output of the scripts are shown in the appendices as well as more specific information about what to configure and test in WFCCN for non-compliance. In addition, each STRS requirement is listed and the type of testing briefly described. Attached is also a set of guidelines on what to look for in addition to the requirements to aid in the document review process.

    Photonics is an inherently interdisciplinary endeavor, as technologies and techniques invented or developed in one scientific field are often found to be applicable to other fields or disciplines. We present two case studies in which optical spectroscopy technologies originating from stellar astrophysics and optical telecommunications multiplexing have been successfully adapted for biomedical applications. The first case involves a design concept called the High Throughput Virtual Slit, or HTVS, which provides high spectral resolution without the throughput inefficiency typically associated with a narrow spectrometer slit. HTVS-enhanced spectrometers have been found to significantly improve the sensitivity and speed of fiber-fed Raman analysis systems, and the method is now being adapted for hyperspectral imaging for medical and biological sensing. The second example of technology transfer into biomedicine centers on integrated optics, in which optical waveguides are fabricated on to silicon substrates in a substantially similar fashion as integrated circuits in computer chips. We describe an architecture referred to as OCTANE which implements a small and robust "spectrometer-on-a-chip" which is optimized for optical coherence tomography (OCT). OCTANE-based OCT systems deliver three-dimensional imaging resolution at the micron scale with greater stability and lower cost than equivalent conventional OCT approaches. Both HTVS and OCTANE enable higher precision and improved reliability under environmental conditions that are typically found in a clinical or laboratory setting.

    A flight-qualified implementation of a Software Defined Radio (SDR) Operating Environment for the JPL-SDR built for the CoNNeCT Project has been developed. It is compliant with the NASA Space Telecommunications Radio System (STRS) Architecture Standard, and provides the software infrastructure for STRS compliant waveform applications. This software provides a standards-compliant abstracted view of the JPL-SDR hardware platform. It uses industry standard POSIX interfaces for most functions, as well as exposing the STRS API (Application Programming In terface) required by the standard. This software includes a standardized interface for IP components instantiated within a Xilinx FPGA (Field Programmable Gate Array). The software provides a standardized abstracted interface to platform resources such as data converters, file system, etc., which can be used by STRS standards conformant waveform applications.

    Bornkessel, Alexandra; Furberg, Robert; Lefebvre, R Craig

    2014-07-01

    Social media brings a new dimension to health care for patients, providers, and their support networks. Increasing evidence demonstrates that patients who are more actively involved in their healthcare experience have better health outcomes and incur lower costs. In the field of cardiology, social media are proposed as innovative tools for the education and update of clinicians, physicians, nurses, and medical students. This article reviews the use of social media by healthcare providers and patients and proposes a model of "networked care" that integrates the use of digital social networks and platforms by both patients and providers and offers recommendations for providers to optimize their use and understanding of social media for quality improvement.

    2015-12-01

    Full Text Available The introduction of mobile number portability (MNP in the Nigerian telecommunications industry has brought a new challenge for mobile operators. This study investigates the use of Analytic Hierarchy Process (AHP in customer retention decisions in the Nigerian telecommunication industry using a cross-sectional survey design. Primary data were obtained through questionnaires administered to 480 mobile telecommunications subscribers in six tertiary institutions located in Lagos State, Nigeria. These educational institutions were chosen using a multistage sampling technique. Of 438 questionnaires received from subscribers, 408 were valid. Based on this sample data an AHP model was built to assess the determinants of customer retention decisions. Next, eigen values, an eigen vector and maximum lambda (λMax were obtained using the AHP analysis for the matrices. This analysis shows that customers considered call quality as the important in the retention decision. We conclude that AHP is a meaningful tool for determining what motivates retention decisions, that can help network operators formulate effective customer retention strategies.

  1. PRISMA as a quality tool for promoting customer satisfaction in the telecommunications industry

    International Nuclear Information System (INIS)

    Near-miss event reporting systems have a successful history in managing risk in industries such as medicine, aviation, nuclear power, and the petrochemical industry. By treating events of customer dissatisfaction as accidents, near-miss event reporting systems designed to reduce risks to safety in hazardous environments may be borrowed by the telecommunications industry. The system chosen for this study was the Prevention and Recovery Information System for Monitoring and Analysis (PRISMA), developed by the Eindhoven University of Technology (EUT). The purpose of this study was to determine the feasibility of applying PRISMA as a tool to reduce risks to customer dissatisfaction. Participants in the project included the EUT Safety Management Group, a consultant, and six Network Service Managers from a telecommunications company whose duties included responding to customer complaints. Twenty-three incidents were investigated with an average of 5.9 root causes arising from 2.9 process owners per event. Causal trees were generated for each incident and root causes were classified according to the Eindhoven Classification Model (ECM). The distribution of 135 root causes was 50% organizational, 32% human, 16% technical and 2% unclassifiable. The participants were successful in executing the functional steps of PRISMA in response to incidents of customer dissatisfaction. This study established the suitability of PRISMA as a tool for managing risks to customer satisfaction within the telecommunications domain

    Full Text Available Abstract Background Primary health care is essential in improving and maintaining the health of populations. It has the potential to accelerate achievement of the Millennium Development Goals and fulfill the “Health for All” doctrine of the Alma-Ata Declaration. Understanding the performance of the health system from a geographic perspective is important for improved health planning and evidence-based policy development. The aims of this study were to measure geographical accessibility, model spatial coverage of the existing primary health facility network, estimate the number of primary health facilities working under capacity and the population underserved in the Western Province of Rwanda. Methods This study uses health facility, population and ancillary data for the Western Province of Rwanda. Three different travel scenarios utilized by the population to attend the nearest primary health facility were defined with a maximum travelling time of 60 minutes: Scenario 1 – walking; Scenario 2 – walking and cycling; and Scenario 3 – walking and public transportation. Considering these scenarios, a raster surface of travel time between primary health facilities and population was developed. To model spatial coverage and estimate the number of primary health facilities working under capacity, the catchment area of each facility was calculated by taking into account population coverage capacity, the population distribution, the terrain topography and the travelling modes through the different land categories. Results Scenario 2 (walking and cycling has the highest degree of geographical accessibility followed by Scenario 3 (walking and public transportation. The lowest level of accessibility can be observed in Scenario 1 (walking. The total population covered differs depending on the type of travel scenario. The existing primary health facility network covers only 26.6% of the population in Scenario 1. In Scenario 2, the use of a bicycle

    Despite calls for more interprofessional and intraprofessional team-based approaches in healthcare, we lack sufficient understanding of how this happens in the context of patient care teams. This multi-perspective, team-based interview study examined how medical teams negotiated collaborative tensions. From 2011 to 2013, 50 patients across five sites in three Canadian provinces were interviewed about their care experiences and were asked to identify members of their health care teams. Patient-identified team members were subsequently interviewed to form 50 "Team Sampling Units" (TSUs), consisting of 209 interviews with patients, caregivers and healthcare providers. Results are gathered from a focused analysis of 13 TSUs where intraprofessional collaborative tensions involved treating fluid overload, or edema, a common HF symptom. Drawing on actor-network theory (ANT), the analysis focused on intraprofessional collaboration between specialty care teams in cardiology and nephrology. The study found that despite a shared narrative of common purpose between cardiology teams and nephrology teams, fluid management tools and techniques formed sites of collaborative tension. In particular, care activities involved asynchronous clinical interpretations, geographically distributed specialist care, fragmented forms of communication, and uncertainty due to clinical complexity. Teams 'disentangled' fluid in order to focus on its physiological function and mobilisation. Teams also used distinct 'framings' of fluid management that created perceived collaborative tensions. This study advances collaborative entanglement as a conceptual framework for understanding, teaching, and potentially ameliorating some of the tensions that manifest during intraprofessional care for patients with complex, chronic disease.

    Mertz, Leslie

    2016-01-01

    In the field of wearable biomedical sensors, the convergence revolution is more than a fanciful, utopian view of the way innovation should be done. Medical-grade wearable sensors rely on it. Their development requires technical know-how, computing expertise, clinical input, and collaboration-a true meeting of the minds to permit the conversion of wearables from neat gadgets into practical and proficient tools that will propel health care to new heights. Beyond the increasing miniaturization of hardware and the shift to wireless communication technology, flexible electronics and more powerful computing capabilities, including application specific integrated circuits (ASICs) and microelectromechanical systems (MEMS), have enabled new work on body sensor networks (BSNs) that monitor, analyze, and make sense of body signals for the prevention, diagnosis, and treatment of health disorders. Developments in processing, such as sensor-connected nodes combined with evolving algorithms and decreasing power requirements, have also contributed. In addition, new approaches to subjective measures (pain and emotion) have opened possibilities. PMID:26799721

    Full Text Available Coordinate rotation digital computer (CORDIC is an efficient algorithm for computations of trigonometric functions. Scaling-free-CORDIC is one of the famous CORDIC implementations with advantages of speed and area. In this paper, a novel direct digital frequency synthesizer (DDFS based on scaling-free CORDIC is presented. The proposed multiplier-less architecture with small ROM and pipeline data path has advantages of high data rate, high precision, high performance, and less hardware cost. The design procedure with performance and hardware analysis for optimization has also been given. It is verified by Matlab simulations and then implemented with field programmable gate array (FPGA by Verilog. The spurious-free dynamic range (SFDR is over 86.85 dBc, and the signal-to-noise ratio (SNR is more than 81.12 dB. The scaling-free CORDIC-based architecture is suitable for VLSI implementations for the DDFS applications in terms of hardware cost, power consumption, SNR, and SFDR. The proposed DDFS is very suitable for medical instruments and body care area network systems.

    An increasing number of patients are developing chronic kidney disease (CKD). Appropriate care for patients with CKD must occur in the earliest stages, preferably before CKD progresses to more severe stages. Therefore, recognition and treatment of CKD and its associated complications must occur in primary care settings. Patients with CKD often have comorbid conditions such as diabetes mellitus, hypertension, and dyslipidemia, creating specific considerations when treating these diseases. Also, these patients have CKD-related conditions, including anemia and renal osteodystrophy, that are not traditionally evaluated and monitored by the primary care practitioner. Collectively, many opportunities exist for pharmacists who practice in the primary care setting to improve the care of patients with CKD. PMID:15767229
