  5. Telecommunications Network Plan

    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

  10. Topological analysis of telecommunications networks

    Directory of Open Access Journals (Sweden)

    Milojko V. Jevtović

    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.

    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.

    2005-08-01

    The operators of telecommunications have targeted their efforts towards realizing applications using broad band fiber optics systems in the access network. Thus, a new concept related to the implementation of fiber optic transmission systems, named FITL (Fiber In The Loop) has appeared. The fiber optic transmission systems have been extensively used for realizing the transport and intercommunication of the public telecommunication network, as well as for assuring the access to the telecommunication systems of the great corporations. Still, the segment of the residential users and small corporations did not benefit on large scale of this technology implementation. For the purpose of defining fiber optic applications, more types of architectures were conceived, like: bus, ring, star, tree. In the case of tree-like networks passive splitters (that"s where the name of PON comes from - Passive Optical Network-), which reduce significantly the costs of the fiber optic access, by separating the costs of the optical electronic components. That's why the passive fiber optics architectures (PON represent a viable solution for realizing the access at the user's loop. The main types of fiber optics architectures included in this work are: FTTC (Fiber To The Curb); FTTB (Fiber To The Building); FTTH (Fiber To The Home).

    The main application and usage of a gigabit-capable passive optical network in a telecommunication network is for providing triple-play services to resident users. However, the gigabit-capable passive optical network itself has more bandwidth than triple-play users need, as well as other mechanisms like the ability to provide quality of service. This excess bandwidth and these advance mechanisms can be utilized for other services and applications inside the same telecommunication network. Some of these advanced applications that use this excess bandwidth and capability of providing quality of service are described, and results of tests are presented in this article.

    Currently, most interplanetary telecommunication systems require human intervention for command and control. However, considering the range from near Earth to deep space missions, combined with the increase in the number of nodes and advancements in processing capabilities, the benefits from communication autonomy will be immense. Likewise, greater mission science autonomy brings the need for unscheduled, unpredictable communication and network routing. While the terrestrial Internet protocols are highly developed their suitability for space exploration has been questioned. JPL has developed the Multi-mission Advanced Communications Hybrid Environment for Test and Evaluation (MACHETE) tool to help characterize network designs and protocols. The results will allow future mission planners to better understand the trade offs of communication protocols. This paper discusses various issues with interplanetary network and simulation results of interplanetary networking protocols.

    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).

    A large scale earthquake was frequently occurred in 1993, 94 causing many damages. Based on the consideration that the telecommunication network has an important role in such the disasters, various measures have been taken from the past. The basic ideas in taking measures for the telecommunication network against disasters are; (1) `Upgrading of system reliability` which includes the strengthening of equipment itself and the redundant composition of network, (2) `Prevention of communication stoppage` which enables to allow communication even when the system is damaged, and (3) `Early reactivation of telecommunication service` when the system is physically damaged. Some examples proved that these approaches taken from the past are effective in the recent seismic disaster. 5 figs., 1 tab.

    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...

    To perform Quantum Key Distribution, the mastering of the extremely weak signals carried by the quantum channel is required. Transporting these signals without disturbance is customarily done by isolating the quantum channel from any noise sources using a dedicated physical channel. However, to really profit from this technology, a full integration with conventional network technologies would be highly desirable. Trying to use single photon signals with others that carry an average power many orders of magnitude bigger while sharing as much infrastructure with a conventional network as possible brings obvious problems. The purpose of the present paper is to report our efforts in researching the limits of the integration of QKD in modern optical networks scenarios. We have built a full metropolitan area network testbed comprising a backbone and an access network. The emphasis is put in using as much as possible the same industrial grade technology that is actually used in already installed networks, in order t...

    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

    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.

    In general, telecommunication facilities do not allow much flexibility in the choice of location; the main criterion is that the facility must work with 100% availability and reliability. Corresponding to the wide spectrum of locations, the applied power supply technologies are very diverse: grid connection, diesel generators, photovoltaics (PV), fuel cells, thermoelectric converters and wind generators. The first three types of technology have been used by the telecommunications industry for decades. The other options are at developmental stages between laboratory samples and limited series production. The traditional approach to supply power remote from the grid is by using diesel generators and storage batteries. This means high power ratings, but also high prices and a high maintenance demand. The convergence of telecommunications networks, i.e. overlap of the cabled network and radio cellular networks, with its enormous demand for installation sites, introduces new demands on power supplies: they must be reliable, maintenance-free, inexpensive, flexibly adaptable to widely divergent technologies. At two examples, a PV-hybrid system for a repeater station for cellular phones and a PV powered intelligent information system, the advantages that offer PV off-grid solutions in the system design are shown.

  5. Photovoltaics for telecommunications networks in Libya, uses and experiences

    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)

    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.

  7. 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.

    2013-04-01

    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

  11. Countrywide rainfall maps from a commercial cellular telecommunication network

    Accurate rainfall observations with high spatial and temporal resolutions are needed for hydrological applications, agriculture, meteorology, and climate monitoring. However, the majority of the land surface of the earth lacks accurate rainfall information. Many countries do not have continuously operating weather radars, and have no or few rain gauges. A new development is rainfall estimation from microwave links of commercial cellular telecommunication networks. Such networks cover large parts of the land surface of the earth and have a high density, especially in urban areas. The estimation of rainfall using commercial microwave links could therefore become a valuable source of information. The data produced by microwave links is essentially a by-product of the communication between mobile telephones. Rainfall attenuates the electromagnetic signals transmitted from one telephone tower to another. By measuring the received power at one end of a microwave link as a function of time, the path-integrated attenuation due to rainfall can be calculated. Previous studies have shown that average rainfall intensities over the length of a link can be derived from the path-integrated attenuation. A dataset from a commercial microwave link network over the Netherlands is analyzed, containing data from an unprecedented number of links (1500) covering the land surface of the Netherlands (35500 km2). This dataset consists of 24 days with substantial rainfall in June - September 2011. A rainfall retrieval algorithm is presented to derive rainfall intensities from the microwave link data, which have a temporal resolution of 15 min. Rainfall maps (1 km spatial resolution) are generated from these rainfall intensities using Kriging. This algorithm is suited for real-time application, and is calibrated on a subset (12 days) of the dataset. The other 12 days in the dataset are used to validate the algorithm. Both calibration and validation are done using gauge-adjusted radar data

    It is predicted that there will be many changes in environment of electric utilities such as expansion of electric power demand, spread of distributed power sources, and changes in market structures due to deregulation. As a first step to think about future telecommunication networks which respond to these changes and adopt technical innovation of telecommunication, present conditions and problems of the current utility telecommunication network are outlined. The utility telecommunication is characterized by high reliability and existence of the information that requires strict transmission delay restriction. The following points are given as the future subjects: although most utility telecommunication networks currently consist of leased lines, they have to be changed to the switched networks for diversifying telecommunication service. It should be considered that the leased line network, which has a hierarchical structure based on a geographical extent, will have a hierarchical structure that is able to correspond to the future telecommunication service. It is better for the current individual loop shape with dual telecommunication circuits to be changed into the overall link shape. In introducing the ATM transmission to improve the path efficiency, it is a premise to secure reliability. 8 refs., 7 figs., 7 tabs.

    Conrad, Stephen H.; O'Reilly, Gerard P.

    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.

  15. Knowledge Discovery Using Bayesian Network Framework for Intelligent Telecommunication Network Management

    Science.gov (United States)

    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.

    In this paper we propose X-MAQoS, a novel XML-based multi-agent system for the QoS management in telecommunications networks. This system is characterized by the following features:(i) it handles a user profile and exploits it jointly with suitable network resource management techniques to maximize user satisfaction; (ii) it is capable of operating in a large variety of telecommunications networks; (iii) it is semi-automatic; (iv) it exploits XML for guaranteeing a light,versatile and standard mechanism for information representation, storing and exchange. In this paper the basic features of the system are discussed in details. Furthermore, the main results of a performance evaluation study in UMTS environment, aiming at comparing X-MAQoS with alternative agent-based approaches for handling user access to telecommunications networks, are reported.

    We demonstrate a fully optical, remote characterization of independent ultrastable lasers separated by a geographical distance of more than 50 km via a 73 km long phase-stabilized fiber in a commercial telecommunication network. The phase-coherent comparison shows a fractional frequency instability between the independent ultrastable laser systems of s_y = 4E-15 for averaging times > 2 s; the remote analog transfer beat note shows a linewidth of 1 Hz. This demonstrates the potential of long-distance remote comparisons of ultrastable optical frequencies using commercial telecommunication fiber networks.

    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.

    Full Text Available Little is known about companies whose core business is selling telecommunications products that lever open source projects. Open source telecommunications (OST companies operate in markets that are very different from typical software product markets. The telecommunications market is regulated, vertically integrated, and proprietary designs and special chips are widely used. For a telecommunications product to be useful, it must interact with both access network products and core network products. Due to specifications in Service Agreements Levels, penalties for failures of telecommunications products are very high. This article shares information that is not widely known, including a list of OST companies and the open source projects on which they depend, the size and diversity of venture capital investment in OST companies, the nature of the commercial product-open source software and company-project relationships, ways in which OST companies make money, benefits and risks of OST companies, and competition between OST companies. Analysis of this information provides insights into the ways in which companies can build business models around open source software. These findings will be of interest to entrepreneurs, top management teams of incumbent companies that sell telecommunications products, and those who care about Ontario's ability to compete globally.

    2012-02-01

    The purpose of this report is to describe the use of telecommunication to improve the quality of postoperative care following microsurgery, especially following microvascular transfer of intestinal transfer for which shortening of ischemia time is of utmost importance to achieve high success rate. From 2003 to 2009 microvascular transfer of intestinal flaps had been performed in 112 patients. After surgery the patients were put in intensive care unit and the flaps were checked every 1 hour. The image for circulatory status of the flaps was sent directly to the attending surgeon for judgment. The information was sent through intranet and the surgeon can get access to the intranet through internet if necessary. Among the 112 cases, there were 9 cases of reexploration. The average duration between the time of problem detection and the time of starting reexploration was 54 min in 7 cases, and other 2 cases were delayed to enter the operating room which had been occupied by other cases of major trauma. Only two flaps were lost completely, two patients developed narrowing at the junction of cervical esophagus and thoracic esophagus. The rate of salvage for intestinal flap is apparently higher than those reported in the literature. In the postoperative management of microsurgery in ICU, telecommunication can help to reduce the ischemia time after vascular compromise in the transfer of free intestinal flap. Telecommunication is really an easy and effective tool in improving the outcome of reconstructive surgery.

    2011-01-01

    Policy-based management (PBM) is being used as technological solution on the managing and controlling complex networks and systems. One of the most important issues involved in the life-cycle of PBM is the policies creation because the future decisions made by the management system depend on this, and therefore, the network behavior. In this paper we present a novel model for creating management policies in telecommunications networks. We propose a model which includes a Policy Creation Process, Actors, Policy Abstraction Levels and a Procedure for Creating Policies. An implementation of the proposed model over the Technology Division at University of Cauca is included.

We show that public telecommunication network carrying Internet data can be used to compare and distribute ultra-stable metrological signals over long distances. This novel technique paves the way for the deployment of a national and continental ultra-stable metrological optical network.

    We demonstrate a cascaded optical link for ultrastable frequency dissemination comprised of two compensated links of 150 km and a repeater station. Each link includes 114 km of Internet fiber simultaneously carrying data traffic through a dense wavelength division multiplexing technology, and passes through two routing centers of the telecommunication network. The optical reference signal is inserted in and extracted from the communication network using bidirectional optical add-drop multiplexers. The repeater station operates autonomously ensuring noise compensation on the two links and the ultra-stable signal optical regeneration. The compensated link shows a fractional frequency instability of 3 x 10(-15) at one second measurement time and 5 x 10(-20) at 20 hours. This work paves the way to a wide dissemination of ultra-stable optical clock signals between distant laboratories via the Internet network.

    1994-05-01

    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.

    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

    2014-01-01

    By using two-way frequency transfer, we demonstrate ultra-high resolution comparison of optical frequencies over a telecommunication fiber link of 100 km operating simultaneously digital data transfer. We first propose and experiment a bi-directional scheme using a single fiber. We show that the relative stability at 1 s integration time is 7 10^18 and scales down to 5 10^21. The same level of performance is reached when an optical link is implemented with an active compensation of the fiber noise. We also implement a real-time two-way frequency comparison over a uni-directional telecommunication network using a pair of parallel fibers. The relative frequency stability is 10^15 at 1 s integration time and reaches 2 10^17 at 40 000 s. The fractional uncertainty of the frequency comparisons was evaluated for the best case to 2 10^20. These results open the way to accurate and high resolution frequency comparison of optical clocks over intercontinental fiber networks.

  6. 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.

  8. Location-allocation models and new solution methodologies in telecommunication networks

    Science.gov (United States)

    Dinu, S.; Ciucur, V.

    2016-08-01

    When designing a telecommunications network topology, three types of interdependent decisions are combined: location, allocation and routing, which are expressed by the following design considerations: how many interconnection devices - consolidation points/concentrators should be used and where should they be located; how to allocate terminal nodes to concentrators; how should the voice, video or data traffic be routed and what transmission links (capacitated or not) should be built into the network. Including these three components of the decision into a single model generates a problem whose complexity makes it difficult to solve. A first method to address the overall problem is the sequential one, whereby the first step deals with the location-allocation problem and based on this solution the subsequent sub-problem (routing the network traffic) shall be solved. The issue of location and allocation in a telecommunications network, called "The capacitated concentrator location- allocation - CCLA problem" is based on one of the general location models on a network in which clients/demand nodes are the terminals and facilities are the concentrators. Like in a location model, each client node has a demand traffic, which must be served, and the facilities can serve these demands within their capacity limit. In this study, the CCLA problem is modeled as a single-source capacitated location-allocation model whose optimization objective is to determine the minimum network cost consisting of fixed costs for establishing the locations of concentrators, costs for operating concentrators and costs for allocating terminals to concentrators. The problem is known as a difficult combinatorial optimization problem for which powerful algorithms are required. Our approach proposes a Fuzzy Genetic Algorithm combined with a local search procedure to calculate the optimal values of the location and allocation variables. To confirm the efficiency of the proposed algorithm with respect

  10. A Feedback Control Mechanism of QoS Management for IP Telecommunication Network

    Institute of Scientific and Technical Information of China (English)

    CUI Yi-dong; JIAO Li; LIN Yu; WANG Wen-dong

    2005-01-01

    In this paper a feedback control mechanism of Quality of Service (QoS) management is proposed. By measuring and monitoring the operational information of the IP telecommunication network, the feedback control-loops tune the network according to the trends of the traffic characteristics in order to gain a favorable network status. With theoretical analysis, it is concluded that the QoS of an arbitrary k-class flow can be guaranteed when the capacity of the k-class traffic is not fully filled. Thus by distributing the bandwidth of the egress bottleneck link among the ingress links, the congestion can be relieved. Moreover, the capacity of each traffic class that shares the same link affects one another. Therefore, the feedback control also aims at adjusting the capacity proportion among the traffic classes. In order to realize the goals, three feedback control-loops are designed in the QoS management system. A CORBA-based implementation is deployed on the testbed.

    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.

    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 number of systems that collect vast amount of data about users rapidly grow during last few years. Many of these systems contain data not only about people characteristics but also about their relationships with other system users. From this kind of data it is possible to extract a social network that reflects the connections between system's users. Moreover, the analysis of such social network enables to investigate different characteristics of its members and their linkages. One of the types of examining such network is key users extraction. Key users are these who have the biggest impact on other network members as well as have big influence on network evolution. The obtained about these users knowledge enables to investigate and predict changes within the network. So this knowledge is very important for the people or companies who make a profit from the network like telecommunication company. The second important thing is the ability to extract these users as quick as possible, i.e. developed the algo...

    International Nuclear Information System (INIS)

    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.

    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.

    By using two-way frequency transfer, we implement a real-time frequency comparison over a uni-directional telecommunication network of 100 km using a pair of parallel fibers with simultaneous digital data transfer. The relative frequency stability is 10-15 at 1-s integration time and reaches 2 ×10-17 at 40 000 s, three orders of magnitude below the one-way fiber instability. We also demonstrate ultrahigh-resolution comparison of optical frequencies with a bidirectional scheme using a single fiber. We show that the relative stability at 1-s integration time is 7 ×10-18 and scales down to 5 ×10-21 . The same level of performance is reached when an optical link is implemented with an active compensation of the fiber noise. The fractional uncertainty of the frequency comparisons was evaluated for the best case to 2 ×10-20 . These results open the way to accurate and high-resolution frequency comparison of optical clocks over intercontinental fiber networks.

    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

    Full Text Available The great challenge of the remarkably growing demand for personal communication mobile service in Libya has actively motivated Al-Madar Telephone Telecommunication Company to adopt various techniques in order to substantially improve its network capacity. An efficient allocation strategy of communication channels that could ensure good performance of the cellular network is critically needed, given the limited spectrum currently available that uses the Fixed Channel Allocation (FCA strategy. In this study, experimental investigations were conducted to improve Al-Madar Company network by proposing the evaluation of the adoption of the Local Packing Distributed Dynamic Channel Allocation (LP-DDCA strategy. The main reasons for proposing the adoption of the LP-DDCA strategy are; to minimize the call blocking probability, enhancing the network performance and increasing the number of network subscribers. This work has been done by applying actual data from an existing cellular network of Al-Madar Company in to the experimental simulation program. The results demonstrated clearly the superiority of the proposed the LP-DDCA strategy in the investigated locations (cells compared with the currently used FCA strategy. Conclusion: Application of the LP-DDCA strategy could give rise to substantial improvement in Al-Madar telecommunication mobile network performance and it will considerably increase the number of network subscribers.

    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.

    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

    The vision of an advanced information system is proposed to cope with the future social demand and business environmental change in electric utilities. At the large turning point such as drastic reconsideration of Electricity Utilities Industry Law, further improvement of efficiency and cost reduction are requested as well as business innovation such as proposal of a new business policy. For that purpose utilization of information and its technology is indispensable, and use of multimedia and common information in organization are the future direction for improving information basis. Consequently, free information networks without any limitation due to person and media are necessary, and the following are important: high-speed, high-frequency band, digital, easily connectable and multimedia transmission lines, and cost reduction and high reliability of networks. Based on innovation of information networks and the clear principle on advanced information system, development of new applications by multimedia technologies, diffusion of communication terminals, and promotion of standardization are essential. 60 refs., 30 figs., 5 tabs.

    An application of various mobile communication systems to the electric power telecommunication network has been investigated. Among these, the customer information network by PHS (personal handy-phone system) has been proposed. Although great numbers of base stations are required for PHS, it can be applied as the customer information network by connecting to the power controller developed by the Central Research Institute of Electric Power Industry. The geostationary satellite telecommunication has been positively utilized by the electric power industry since the Hanshin-Awaji Great Earthquake. It can be used as the customer information network in the future. Since the radio access is a one-way communication, it cannot be applied to the electric power telecommunication network at present. It can be applied to the simple message communication or relatively low-speed data communication through the two-way communication. Public ground mobile telecommunication in the future includes various mobile telecommunication systems. To start the operation in 2000, the ITU (International Telecommunication Union) is making specifications common in the world. It is required to investigate the utilization as multipurpose systems. The network for PHS can be applied to the telecommunication network without optical cable. 20 refs., 5 figs., 3 tabs.

    Full Text Available A Command Information System (CIS in a broader sense can be defined as a set of hardware and software solutions by which one achieves real-time integration of organizational structures, doctrine, technical and technological systems and facilities, information flows and processes for efficient and rational decision-making and functioning. 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

    2004-01-01

    Full Text Available The tariff policy of a telecommunication operator has a strategic importance on achieving of optimal revenues and a fundamental impact on its position in the competition with another operators on the liberalised telecommunication market. The payment for a connection through a telecommunication network is determined by a rate for one call unit, by the duration of the call unit and their count during a call. An operator derives the rate and the duration of the call unit from a detailed analysis of large databases that contain statistical data on counts and duration of particular calls depending on the call type. Only the operator knows these data files and it keeps them confidential. It will be shown in the paper how it is possible to come to an estimation of revenues from telecommunication traffic only knowing a pair of basic parameters. The first considerations handling with this topic can be found in [1], [2],[3].

  14. 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

    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。

    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

  6. 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

    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.

  4. 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

    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.

    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

  5. TELECOMMUNICATIONS INFRASTRUCTURE AND GDP /JIPP CURVE/

    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.

  6. Complementary and alternative medicine for children's asthma: satisfaction, care provider responsiveness, and networks of care.

    Science.gov (United States)

    Freidin, Betina; Timmermans, Stefan

    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.

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.

    1975-01-01

    The Health/Education Telecommunications Experiment (HET) was conducted jointly by NASA and HEW on NASA's ATS-6 communications satellite. This experiment actually consisted of six experiments testing health and education applications of a communication spacecraft producing a broadcast of color television directly from space to over 120 low-cost receivers located in remote rural areas throughout the U.S. (including Alaska). The experiments were conducted over the period from 2 July 1974 to 20 May 1975 and operated on an almost daily basis. The overall telecommunications system to support these experiments consisted of many elements: The ATS-6 spacecraft; five different types of earth stations consisting of 120 video receive terminals, 51 telephony tranceivers and eight video originating terminals of three different types. Actual performance of the equipment as measured in the field was shown to equal or exceed predicted values.

    This book contains the proceedings of the first international symposium devoted to research on the evaluation and planning of new person-to-person telecommunication systems. 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. (This excludes management information systems in which the computer performs important transformat...

    The paper offers an overview of the literature on bundling in the telecommunications sector and its application in the Spanish market. We argue that the use of bundling in the provision of services is associated to technological reasons. Therefore, there appears no need to regulate bundling activities. However, this is not to say that other related telecom markets should not be scrutinized and regulated, or that the regulator should not pay attention to other bundling-related anticompetitive ...

    Multi-Mission Telecom Analysis Tool (MMTAT) is a C-language computer program for analyzing proposed spacecraft telecommunication systems. MMTAT utilizes parameterized input and computational models that can be run on standard desktop computers to perform fast and accurate analyses of telecommunication links. MMTAT is easy to use and can easily be integrated with other software applications and run as part of almost any computational simulation. It is distributed as either a stand-alone application program with a graphical user interface or a linkable library with a well-defined set of application programming interface (API) calls. As a stand-alone program, MMTAT provides both textual and graphical output. The graphs make it possible to understand, quickly and easily, how telecommunication performance varies with variations in input parameters. A delimited text file that can be read by any spreadsheet program is generated at the end of each run. The API in the linkable-library form of MMTAT enables the user to control simulation software and to change parameters during a simulation run. Results can be retrieved either at the end of a run or by use of a function call at any time step.

    Full Text Available Users' satisfaction is an important end-point to evaluate health services. This study has to do with an assessment of the level of user's satisfaction with relation to the last visit held in the primary health care network of Porto Alegre — RS, whose objective is to compare satisfaction of the users that assess the quality of the care process received as being of high APS score with that of the users who evaluate it as low APS score. A cross-sectional study based on the population, using the Primary Care Assessment Tool - PCATool, which enables the classification of the health services at the level of guidance to APS by means of the general score of primary care, defining it as high or low, in accordance with the users' experience. The satisfaction of the user was measured by a questionnaire consisting of twelve questions relative to the last visit, being measured by a 5-item Likert scale: "very good", "good", "regular", "bad" and "very bad". For the analysis, the results were grouped into two classifications, i.e. "satisfied", when referred as "veg good" or "good", and "dissatisfied" when referred to any of the other items. A significant difference was noticed in the 12 variables reflecting satisfaction in several aspects of the visit, showing higher satisfaction in users that classified the service as being of high score. The .general evaluation of the service presented 95.6% and 73.5% of "satisfied" in the services with high and low APS score, respectively (p<0.001. Users of services with high level of guidance to primary care obtain higher satisfaction in their visits. This higher satisfaction can benefit the decision-making process of the patient in face of the medical recommendations made.

  19. 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.

    2015-07-01

    Full Text Available Background: Integrated health care networks (IHN are promoted in numerous countries as a response to fragmented care delivery by providing a coordinated continuum of services to a defined population. However, evidence on their effectiveness and outcome is scarce, particularly considering continuity across levels of care; that is the patient's experience of connected and coherent care received from professionals of the different care levels over time. The objective was to analyse the chronic obstructive pulmonary disease (COPD patients’ perceptions of continuity of clinical management and information across care levels and continuity of relation in IHN of the public health care system of Catalonia.Methods: A qualitative multiple case study was conducted, where the cases are COPD patients. A theoretical sample was selected in two stages: (1 study contexts: IHN and (2 study cases consisting of COPD patients. Data were collected by means of individual, semi-structured interviews to the patients, their general practitioners and pulmonologists and review of records. A thematic content analysis segmented by IHN and cases with a triangulation of sources and analysists was carried out.Results: COPD patients of all networks perceived that continuity of clinical management was existent due to clear distribution of roles for COPD care across levels, rapid access to care during exacerbations and referrals to secondary care when needed; nevertheless, patients of some networks highlighted too long waiting times to non-urgent secondary care. Physicians generally agreed with patients, however, also indicated unclear distribution of roles, some inadequate referrals and long waiting times to primary care in some networks. Concerning continuity of information, patients across networks considered that their clinical information was transferred across levels via computer and that physicians also used informal communication mechanisms (e-mail, telephone; whereas

    One third of all practicing physicians are currently working in one of the 400 German health care networks. These physicians' networks bring together GPs and specialists and cooperate with different partners, for example, nursing homes, hospitals, and self-help groups. To increase the quality and the efficiency of care and patient satisfaction by improving the collaboration and communication between physicians and other health care providers.The example of the accountable care organization "Gesundheitsnetz Qualität und Effizienz" (QuE; Health Quality and Efficiency Network) in Nuremberg is used to show that it is possible to achieve an increase in efficiency while providing above-average quality of care and achieving high patient satisfaction. Additionally, the article deals with the status quo, the core objectives, and the key activities of previous generations of health care networks. Quality indicators, satisfaction surveys, and economic parameters are the basis for measuring and representing the above-average performance of physicians' networks. Regional health care networks offer an entire range of patient care, from outpatients and inpatients to the complementary sector, and thereby have excellent prospects for playing an even more important role in the German health care system. The key success factors are: the consideration of specific regional characteristics, their proximity to the patient, and consistent patient orientation.

    1996-12-31

    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.

    Full Text Available 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.

    Full Text Available Abstract Background Extended follow-up of survivors of ICU treatment has shown many patients suffer long-term physical and psychological consequences that affect their health-related quality of life. The current lack of rigorous longitudinal studies means that the true prevalence of these physical and psychological problems remains undetermined. Methods/Design The ICON (Intensive Care Outcome Network study is a multi-centre, longitudinal study of survivors of critical illness. Patients will be recruited prior to hospital discharge from 20–30 ICUs in the UK and will be assessed at 3, 6, and 12 months following ICU discharge for health-related quality of life as measured by the Short Form-36 (SF-36 and the EuroQoL (EQ-5D; anxiety and depression as measured by the Hospital Anxiety and Depression Scale (HADS; and post traumatic stress disorder (PTSD symptoms as measured by the PTSD Civilian Checklist (PCL-C. Postal questionnaires will be used. Discussion The ICON study will create a valuable UK database detailing the prevalence of physical and psychological morbidity experienced by patients as they recover from critical illness. Knowledge of the prevalence of physical and psychological morbidity in ICU survivors is important because research to generate models of causality, prognosis and treatment effects is dependent on accurate determination of prevalence. The results will also inform economic modelling of the long-term burden of critical illness. Trial Registration ISRCTN69112866

    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.

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.

    The design and administration of a departmental computer network (Local Area Network) in anesthesiology and intensive care offer the opportunity to manage clinical information and control the work-flow. To improve the local network, after basic design, intelligence is necessary to maintain its efficiency. For this reason the role of a medical administrator of the network is fundamental because he is a qualified figure who recognizes the most important characteristics that a network must have, knows the users of the system, represents a valid consultant for the technician that has to build the network, and is able to face possible breakdowns. This paper illustrates the structure of a course to train a medical network administrator in anesthesiology and critical care.

    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.

    To construct an advanced operation and management system for utility telecommunications management network (TMN), this paper proposes a modeling method of managed objects (MOs) required for managing and managed systems, such as an asynchronous transmission mode (ATM) exchanger. Flexible line setting and path switching control are required for the advanced TMN, which must cope with the extension and modification of functions, flexibly. Assignment of roles of managing sides and managed sides was determined. Then, structures of objects such as facilities and logic data, and their interaction were modeled. Common management functions and objects of each function were classified. Based on the TMN standard and MOs of the existing design peculiar to utility, new MOs peculiar to utility were defined in response to the models. The existing MOs can be effectively utilized, and the optimum MOs to be incorporated can be expected. The MOs peculiar to utility are added to the common specification of electric power industry. Since they can be reused for the extension and modification of functions, the cost can be reduced. The MOs applicable to path switching control of utility were designed as a trial. 9 refs., 16 figs., 10 tabs.

    Correa, Gonzalo; Domènech, Miquel

    2013-07-01

    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.

    Full Text Available Telecommunication is very important as it serves various activities, services of electronic systems to transmit messages via physical cables, telephones, or cell phones. 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.

    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.

    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

    Full Text Available Purpose: To investigate the set up and operation of a Managed Clinical Network for cardiac services and assess its impact on patient care. Methods: This single case study used process evaluation with observational before and after comparison of indicators of quality of care and costs. The study was conducted in Dumfries and Galloway, Scotland and used a three-level framework. Process evaluation of the network set-up and operation through a documentary review of minutes; guidelines and protocols; transcripts of fourteen semi-structured interviews with health service personnel including senior managers, general practitioners, nurses, cardiologists and members of the public. Outcome evaluation of the impact of the network through interrupted time series analysis of clinical data of 202 patients aged less than 76 years admitted to hospital with a confirmed myocardial infarction one-year pre and one-year post, the establishment of the network. The main outcome measures were differences between indicators of quality of care targeted by network protocols. Economic evaluation of the transaction costs of the set-up and operation of the network and the resource costs of the clinical care of the 202 myocardial infarction patients from the time of hospital admission to 6 months post discharge through interrupted time series analysis. The outcome measure was different in National Health Service resource use. Results: Despite early difficulties, the network was successful in bringing together clinicians, patients and managers to redesign services, exhibiting most features of good network management. The role of the energetic lead clinician was crucial, but the network took time to develop and ‘bed down’. Its primary “modus operand” was the development of a myocardial infarction pathway and associated protocols. Of sixteen clinical care indicators, two improved significantly following the launch of the network and nine showed improvements, which were

  20. Clinic Network Collaboration and Patient Tracing to Maximize Retention in HIV Care.

    Directory of Open Access Journals (Sweden)

    James H McMahon

    Full Text Available Understanding retention and loss to follow up in HIV care, in particular the number of people with unknown outcomes, is critical to maximise the benefits of antiretroviral therapy. Individual-level data are not available for these outcomes in Australia, which has an HIV epidemic predominantly focused amongst men who have sex with men.A network of the 6 main HIV clinical care sites was established in the state of Victoria, Australia. Individuals who had accessed care at these sites between February 2011 and June 2013 as assessed by HIV viral load testing but not accessed care between June 2013 and February 2014 were considered individuals with potentially unknown outcomes. For this group an intervention combining cross-referencing of clinical data between sites and phone tracing individuals with unknown outcomes was performed. 4966 people were in care in the network and before the intervention estimates of retention ranged from 85.9%-95.8% and the proportion with unknown outcomes ranged from 1.3-5.5%. After the intervention retention increased to 91.4-98.8% and unknown outcomes decreased to 0.1-2.4% (p<.01 for all sites for both outcomes. Most common reasons for disengagement from care were being too busy to attend or feeling well. For those with unknown outcomes prior to the intervention documented active psychiatric illness at last visit was associated with not re-entering care (p = 0.04.The network demonstrated low numbers of people with unknown outcomes and high levels of retention in care. Increased levels of retention in care and reductions in unknown outcomes identified after the intervention largely reflected confirmation of clinic transfers while a smaller number were successfully re-engaged in care. Factors associated with disengagement from care were identified. Systems to monitor patient retention, care transfer and minimize disengagement will maximise individual and population-level outcomes for populations with HIV.

    Purpose The purpose of this paper of inter-professional networks is to analyze the evolution of relationships between professional groups enacting new forms of collaboration to address clinical imperatives. Design/methodology/approach This paper uses a case study based on semi-structured interviews with physicians and nurses, document analysis and informal discussions. Findings This study documents how two inter-professional networks were developed through professional agency. The findings show that the means by which networks are developed influence the form of collaboration therein. One of the networks developed from day-to-day, immediately relevant, exchange, for patient care. The other one developed from more formal and infrequent research and training exchanges that were seen as less decisive in facilitating patient care. The latter resulted in a loosely knit network based on a small number of ad hoc referrals while the other resulted in a tightly knit network based on frequent referrals and advice seeking. Practical implications Developing inter-professional networks likely require a sustained phase of interpersonal contacts characterized by persuasion, knowledge sharing, skill demonstration and trust building from less powerful professional groups to obtain buy-in from more powerful professional groups. The nature of the collaboration in any resulting network depends largely on the nature of these initial contacts. Originality/value The literature on inter-professional healthcare networks focusses on mandated networks such as NHS managed care networks. There is a lack of research on inter-professional networks that emerged from the bottom up at the initiative of healthcare professionals in response to clinical imperatives. This study looks at some forms of collaboration that these "grass-root" initiatives engender and how they are consolidated. PMID:27681028

  2. Effect of social networks and well-being on acute care needs.

    The effect of social surroundings has been noted as an important component of the well-being of elderly people. A strong social network and strong and steady relationships are necessary for coping when illness or functional limitations occur in later life. Vulnerability can affect well-being and functioning particularly when sudden life changes occur. The objective of this study was to analyse how the determinants of social well-being affect individual acute care needs when sudden life changes occur. Empirical evidence was collected using a cross-sectional mail survey in Finland in January 2011 among individuals aged 55-79 years. The age-stratified random sample covered 3000 individuals, and the eventual response rate was 56% (1680). Complete responses were received from 1282 respondents (42.7%). The study focuses on the compactness of social networks, social disability, the stability of social relationships and the fear of loneliness as well as how these factors influence acute care needs. The measurement was based on a latent factor structure, and the key concepts were measured using two ordinal items. The results of the structural model suggest that the need for care is directly affected by social disability and the fear of loneliness. In addition, social disability is a determinant of the fear of loneliness and therefore plays an important role if sudden life changes occur. The compactness of social networks decreases social disability and partly diminishes the fear of loneliness and therefore has an indirect effect on the need for care. The stability of social relationships was influenced by the social networks and disability, but was an insignificant predictor of care needs. To conclude, social networks and well-being can decrease care needs, and supportive actions should be targeted to avoid loneliness and social isolation so that the informal network could be applied as an aspect of care-giving when acute life changes occur.

    Wales, A; Graham, S; Rooney, K; Crawford, A

    2012-11-01

    The Knowledge Network (www.knowledge.scot.nhs.uk) is Scotland's online knowledge service for health and social care. It is designed to support practitioners to apply knowledge in frontline delivery of care, helping to translate knowledge into better health-care outcomes through safe, effective, person-centred care. The Knowledge Network helps to combine the worlds of evidence-based practice and quality improvement by providing access to knowledge about the effectiveness of clinical interventions ('know-what') and knowledge about how to implement this knowledge to support individual patients in working health-care environments ('know-how'). An 'evidence and guidance' search enables clinicians to quickly access quality-assured evidence and best practice, while point of care and mobile solutions provide knowledge in actionable formats to embed in clinical workflow. This research-based knowledge is complemented by social networking services and improvement tools which support the capture and exchange of knowledge from experience, facilitating practice change and systems improvement. In these cases, the Knowledge Network supports key components of the knowledge-to-action cycle--acquiring, creating, sharing and disseminating knowledge to improve performance and innovate. It provides a vehicle for implementing the recommendations of the national Knowledge into Action review, which outlines a new national approach to embedding knowledge in frontline practice and systems improvement.

There is considerable evidence that quality factors affecting customer satisfaction in numerous ways. However, this empirical study is initiated to find out what particular factors responsible for customer satisfaction in the mobile tel- ecommunication industry in Bangladesh. 282 samples have been collected through structured questionnaire; study reveals that service innovativeness, service reli- ability, service competitiveness and service consistency have significant influence on making customer satisfied and the operator’s network/signal coverage, pricing, offering, fulfillment of customer demand, value added service, brand value and op - erators contribution for society have insignificant influences on making customer satisfied at five percent level of significant at multiple regression analysis. On the basis of these findings; study concludes that in promoting customer satisfaction mobile service providers should be concerned for factors responsible for insignifi- cant influence on customer satisfaction and care of those factors have significant influence on promoting customer satisfaction in telecommunication industry in Bangladesh.

  7. 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

    2015-01-01

    Many normative beliefs are shared and learned through interpersonal communication, yet research on norms typically focuses on their effects rather than the communication that shapes them. This study focused on interpersonal communication during pregnancy to uncover (a) the nature of pregnancy-related communication and (b) normative information transmitted through such communication. Results from interviews with pregnant women living in rural Mexico revealed limited social networks; often, only a woman's mother or the baby's father were consulted about prenatal care decisions. However, women also indicated that communication with others during pregnancy provided important normative information regarding prenatal care. First, most referents believed that women should receive prenatal care (injunctive norm), which was conceptualized by participants as biomedical, nonmedical, or a blend of both. Second, family members often received prenatal care, whereas friends did not (descriptive norms). These findings highlight the key role of personal and social networks in shaping personal pregnancy-related beliefs and behaviors.

  11. 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...

    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

    Quantum cryptography has shown the potential for ultra-secure communications. However, all systems demonstrated to date operate at speeds that make them impractical for performing continuous one-time-pad encryption of today's broadband communications. By adapting clock and data recovery techniques from modern telecommunications engineering practice, and by designing and implementing expeditious error correction and privacy amplification algorithms, we have demonstrated error-corrected and privacy-amplified key rates up to 1.0 Mbps over a free-space link with a 1.25 Gbps clock. Using new detectors with improved timing resolution, careful wavelength selection and an increased clock speed, we expect to quadruple the transmission rate over a 1.5 km free-space link. We have identified scalable solutions for delivering sustained one-time-pad encryption at 10 Mbps, thus making it possible to integrate quantum cryptography with first-generation Ethernet protocols.

    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 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.

    Full Text Available Background The use of medication is at the heart of primary care, but is also the cause for major health concerns. It is therefore important to examine the prescription of medication process.Objective This study identifies the barriers and facilitators perceived by community pharmacists and primary care physicians concerning the adoption of a nationwide electronic prescribing (e-prescribing network in the province of Quebec, Canada.Methods We used purposive sampling to identify the most intensive users of the e-prescribing network. We conducted phone and in-person interviews. Interviews were transcribed, and we analysed their content with NVivo, using the clinical adoption framework (CAF for the codification of the data.Results We interviewed 33 pharmacists, 2 pharmacy technicians, 11 physicians and 3 clinic managers. Adoption of the e-prescribing network was fairly low. The respondents underlined adaptation of their work environment, openness to change and perception of benefits as facilitators to the adoption of the network. However, important barriers were perceived, including system quality issues and paper prescriptions being the only legal document in the prescribing process. Even if respondents recognised that the e-prescribing network can offer substantial benefits to the prescribing process, issues still persisted and raised barriers to the full use of such a network, especially in a context where different local information systems are connected within a nationwide e-prescribing network.Conclusion This study, based on the CAF, provides a better understanding of the factors related to the adoption of a nationwide e-prescribing network connecting primary care clinics and community pharmacies.

    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.

    2016-01-01

    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.

    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.

    Deutsch, Larry

    1995-10-01

    Health care is at its best when both the practitioner and patient are well-informed. In many central urban and remote rural areas, however, health care is characterized by a lack of continuity and coordination among providers. In these areas, a local information infrastructure and a patient-centered system of primary care are missing. Decision-making and ability to follow through is hampered, with limited involvement of patients in planning care and insufficient aggregate data for cost analysis, outcome research, community health planning, and other purposes. A Children's Health Network has been designed to extend current information technology to these underserved areas. Our approach to improving quality of individual care and controlling costs emphasizes use of computerized clinical information networks for better decision making and continuity, and secondarily through data aggregation for financial, research, and public health functions. This is in distinction to information systems centered on billing and administrative needs and to cost-control efforts which rely on fiscal and managerial ('gatekeeper') mechanisms. A uniform data base among sites serving the same population will answer several clinical and public health needs.

    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.

    Turner syndrome, a congenital condition that affects ∼1/2,500 births, results from absence or structural alteration of the second sex chromosome. There has been substantial effort by numerous clinical and genetic research groups to delineate the clinical, pathophysiological, cytogenetic, and molecular features of this multisystem condition. Questions about the molecular-genetic and biological basis of many of the clinical features remain unanswered, and health care providers and families seek improved care for affected individuals. The inaugural "Turner Resource Network (TRN) Symposium" brought together individuals with Turner syndrome and their families, advocacy group leaders, clinicians, basic scientists, physician-scientists, trainees and other stakeholders with interest in the well-being of individuals and families living with the condition. The goal of this symposium was to establish a structure for a TRN that will be a patient-powered organization involving those living with Turner syndrome, their families, clinicians, and scientists. The TRN will identify basic and clinical questions that might be answered with registries, clinical trials, or through bench research to promote and advocate for best practices and improved care for individuals with Turner syndrome. The symposium concluded with the consensus that two rationales justify the creation of a TRN: inadequate attention has been paid to the health and psychosocial issues facing girls and women who live with Turner syndrome; investigations into the susceptibility to common disorders such as cardiovascular or autoimmune diseases caused by sex chromosome deficiencies will increase understanding of disease susceptibilities in the general population.

    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.

    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

    2010-04-01

    Full Text Available Abstract Background The Primary Community Care Network (PCCN Demonstration Project, launched by the Bureau of National Health Insurance (BNHI in 2003, is still in progress. Partnership structures in PCCNs represent both contractual clinic-to-clinic and clinic-to-hospital member relationships of organizational aspects. The partnership structures are the formal relationships between individuals and the total network. Their organizational design aims to ensure effective communication, coordination, and integration across the total network. Previous studies have focused largely on how contractual integration among the partnerships works and on its effects. Few studies, however, have tried to understand partnership disengagement in PCCNs. This study explores why some partnerships in PCCNs disengage. Methods This study used a qualitative methodology with semi-structured questions for in-depth interviews. The semi-structured questions were pre-designed to explore the factors driving partnership disengagement. Thirty-seven clinic members who had withdrawn from their PCCNs were identified from the 2003-2005 Taiwan Primary Community Care Network Lists. Results Organization/participant factors (extra working time spend and facility competency, network factors (partner collaboration, and community factors (health policy design incompatibility, patient-physician relationship, and effectiveness are reasons for clinic physicians to withdraw or change their partnerships within the PCCNs. Conclusions To strengthen partnership relationships, several suggestions are made, including to establish clinic and hospital member relationships, and to reduce administrative work. In addition, both educating the public about the concept of family doctors and ensuring well-organized national health policies could help health care providers improve the integration processes.

    2012-02-01

    The PC program of the Italian speaking part of Switzerland (Ticino) has been developed bottom up since 1990. It was started with a palliative homecare service, called Hospice Ticino. Six years later PC consultant teams were introduced in the public hospitals. Finally in 2003 an acute palliative care unit was opened. Few resources are still lacking to ensure a comprehensive network, especially in the private clinics and in the elderly homes. Through the newly implemented National Strategy in PC 2010 - 12, the government of Canton Ticino has been charged with promoting a comprehensive, strategic and operative program in PC in order to guarantee access to high quality PC to every patient wherever he choses to be cared for. The article describes the history of Ticino's palliative care program, highlighting some of its controversial issues.

    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.

    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.

    2004-07-01

    In this paper, we provide the economic rationale for an important issue in the health care sector, namely the network formation, e.g., in The Netherlands. The presence of such cooperation structures is hard to explain using the basic concept of the economic organization (EO) theory, i.e., the dichotomy of hierarchy versus market. However, acknowledging the aspect of trust renders the clan concept to be a powerful tool in understanding the viability of intra- and inter-organizational cooperation in the health sector. The main reason for this is the manner in which the professionals involved perform, as well as the importance of the tacit knowledge of the actors employed in the various health institutions. First, we address the conversion from supply towards demand orientation and the resulting pressure on multi-professional cooperation between health care providers. Then, relevant EO concepts will be reviewed, while introducing theory on knowledge, learning, and trust. Moreover, we offer conclusions for the health care sector on a concept-by-concept basis. Finally, we propose the notion of interclan, a clan-inspired notion for inter-organizational cooperation, and analyse the observed network formation.

  12. 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.

    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.

  16. Lanthanide NIR luminescence for telecommunications, bioanalyses and solar energy conversion

    Jean-Claude; G.; Bünzli; V.

    2010-01-01

    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.

    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.

  1. Bio-inspired Autonomic Structures: a middleware for Telecommunications Ecosystems

    Manzalini, Antonio; Minerva, Roberto; Moiso, Corrado

    Today, people are making use of several devices for communications, for accessing multi-media content services, for data/information retrieving, for processing, computing, etc.: examples are laptops, PDAs, mobile phones, digital cameras, mp3 players, smart cards and smart appliances. One of the most attracting service scenarios for future Telecommunications and Internet is the one where people will be able to browse any object in the environment they live: communications, sensing and processing of data and services will be highly pervasive. In this vision, people, machines, artifacts and the surrounding space will create a kind of computational environment and, at the same time, the interfaces to the network resources. A challenging technological issue will be interconnection and management of heterogeneous systems and a huge amount of small devices tied together in networks of networks. Moreover, future network and service infrastructures should be able to provide Users and Application Developers (at different levels, e.g., residential Users but also SMEs, LEs, ASPs/Web2.0 Service roviders, ISPs, Content Providers, etc.) with the most appropriate "environment" according to their context and specific needs. Operators must be ready to manage such level of complication enabling their latforms with technological advanced allowing network and services self-supervision and self-adaptation capabilities. Autonomic software solutions, enhanced with innovative bio-inspired mechanisms and algorithms, are promising areas of long term research to face such challenges. This chapter proposes a bio-inspired autonomic middleware capable of leveraging the assets of the underlying network infrastructure whilst, at the same time, supporting the development of future Telecommunications and Internet Ecosystems.

    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.)

  3. Participation and coordination in Dutch health care policy-making. A network analysis of the system of intermediate organizations in Dutch health care.

    2013-06-01

    This study explores the system of intermediate organizations in Dutch health care as the crucial system to understand health care policy-making in the Netherlands. We argue that the Dutch health care system can be understood as a system consisting of distinct but inter-related policy domains. In this study, we analyze four such policy domains: Finances, quality of care, manpower planning and pharmaceuticals. With the help of network analytic techniques, we describe how this highly differentiated system of >200 intermediate organizations is structured and coordinated and what (policy) consequences can be observed with regard to its particular structure and coordination mechanisms. We further analyze the extent to which this system of intermediate organizations enables participation of stakeholders in policy-making using network visualization tools. The results indicate that coordination between the different policy domains within the health care sector takes place not as one would expect through governmental agencies, but through representative organizations such as the representative organizations of the (general) hospitals, the health care consumers and the employers' association. We further conclude that the system allows as well as denies a large number of potential participants access to the policy-making process. As a consequence, the representation of interests is not necessarily balanced, which in turn affects health care policy. We find that the interests of the Dutch health care consumers are well accommodated with the national umbrella organization NPCF in the lead. However, this is no safeguard for the overall community values of good health care since, for example, the interests of the public health sector are likely to be marginalized.

    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

    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

    Severe hand traumata have a significant impact on our health system and on insurance companies, respectively. It is estimated that 33% of all occupational injuries and 9% of all invalidity pensions are due to severe hand trauma. Unfortunately, these high numbers are not only due to the severity of the trauma but to organisational deficiencies. Usually, the patient is treated at the general surgical emergency in the first place and only then forwarded to a microsurgeon. This redirection increases the time that is required for the patient to finally arrive at an expert for hand surgery. On the one hand, this problem can be explained by the population's lack of awareness for distinguished experts for hand and microsurgery, on the other hand, the emergency network, or emergency doctors in particular are not well informed about where to take a patient with a severe hand trauma - clearly a problem of communication between the hospitals and the ambulance. It is possible to tackle this problem, but put participating hand trauma centres have to work hand in hand as a network and thus exploit synergy effects. The French system "FESUM" is a good example for such a network and even comprises centres in Belgium and Switzerland. To improve the treatment of severe hand trauma, a similar alliance was initiated in Germany just recently. The pilot project "Hand Trauma Alliance" (www.handverletzung.com) was started in April 2013 and currently comprises two hospitals within the region of upper Bavaria. The network provides hand trauma replantation service on a 24/7 basis and aims at shortening the way from the accident site to the fully qualified hand surgeon, to improve the therapy of severe hand injuries and to optimise acute patient care in general. In order to further increase the alliance's impact it is intended to extend the project's scope from regional to national coverage - nevertheless, such an endeavour can only be done in collaboration with the German Society for Hand

    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.

    We explore the argument that a new mode of health care organizing is emerging which moves beyond the established professional dominance versus New Public Management (NPM) debate. We review Foucault's work on 'governmentality', as applied to health care organizations. We specify two specific Foucauldian themes (the power/knowledge nexus in Evidence Based Medicine (EBM); and the technologies of the clinical managerial self) to analyse organizing in the English cancer services field. We introduce two qualitative case studies of Managed Cancer Networks. We suggest their governance can be fruitfully seen through a 'governmentality' lens. We consider implications for developing Foucauldian analysis of health care organizations.

    Through strategic clinical diversification, political activism, and bold expansion, Wills Eye Hospital, a teaching specialty surgical hospital, survives ravages of sudden onslaughts of managed care payment reductions while maintaining autonomy. Slack inpatient resources were re-utilized to create unique programs attractive to regional managed care organizations. Advocacy and lobbying for short-term favorable treatment from Medicare bought the Hospital valuable time and positioning. Building out a regional network of ambulatory surgical centers assures the growth and access to market required for Wills to maintain its autonomy in a managed care contracting environment.

    Full Text Available 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.

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

    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

    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.

    2011-07-01

    Full Text Available Global information and communication technologies permeate organizational structures, while questions of security pervade strategic plans of corporations worldwide. From the spectacular to the sublime, the effects of geomagnetic disturbances (i.e., electrical current produced by solar storms can be as devastating to an organization’s telecommunications systems as a hacker breaching a firewall. Using a dataset spanning 31 years (1978-2009 with 580,000 solar activity records, we investigate the effects and relationships of natural anomalies, specifically solar storms, on the security of corporate telecommunications. The ionosphere is a natural barrier around the earth to protect it from the sun and serve as a shield, but some electrical currents break this barrier causing significant telecommunications outages and security breaches within corporations. In this exploratory empirical study, we present the initial evidence that tracking geomagnetic disturbances can provide vital cautions for business continuity planning. The results of the study should help organizations with strategic planning efforts with respect to their overall security, especially as it relates to telecommunications.

  2. Twenty-Five Years of Applications of the Modified Allan Variance in Telecommunications.

    Science.gov (United States)

    Bregni, Stefano

    2016-04-01

    The Modified Allan Variance (MAVAR) was originally defined in 1981 for measuring frequency stability in precision oscillators. Due to its outstanding accuracy in discriminating power-law noise, it attracted significant interest among telecommunications engineers since the early 1990s, when it was approved as a standard measure in international standards, redressed as Time Variance (TVAR), for specifying the time stability of network synchronization signals and of equipment clocks. A dozen years later, the usage of MAVAR was also introduced for Internet traffic analysis to estimate self-similarity and long-range dependence. Further, in this field, it demonstrated superior accuracy and sensitivity, better than most popular tools already in use. This paper surveys the last 25 years of progress in extending the field of application of the MAVAR in telecommunications. First, the rationale and principles of the MAVAR are briefly summarized. Its adaptation as TVAR for specification of timing stability is presented. The usage of MAVAR/TVAR in telecommunications standards is reviewed. Examples of measurements on real telecommunications equipment clocks are presented, providing an overview on their actual performance in terms of MAVAR. Moreover, applications of MAVAR to network traffic analysis are surveyed. The superior accuracy of MAVAR in estimating long-range dependence is emphasized by highlighting some remarkable practical examples of real network traffic analysis.

  3. Investigating the quality of video consultations performed using fourth generation (4G) mobile telecommunications.

    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

    Energy savings in residential sector can be performed by home integrated control systems. Remote controlled interfaces allow electric appliances consumption matching effective needs. Nevertheless, the uses of those techniques are stagnating since several years. The first reason is an awkward human factors engineering, that is now improving. The second reason is an lack of definition of the needs, that lead to commercialization problems. (D.L.)

    2015-05-01

    In many countries formal or informal palliative care networks (PCNs) have evolved to better integrate community-based services for individuals with a life-limiting illness. We conducted a cross-sectional survey using a customized tool to determine the perceptions of the processes of palliative care delivery reflective of horizontal integration from the perspective of nurses, physicians and allied health professionals working in a PCN, as well as to assess the utility of this tool. The process elements examined were part of a conceptual framework for evaluating integration of a system of care and centred on interprofessional collaboration. We used the Index of Interdisciplinary Collaboration (IIC) as a basis of measurement. The 86 respondents (85% response rate) placed high value on working collaboratively and most reported being part of an interprofessional team. The survey tool showed utility in identifying strengths and gaps in integration across the network and in detecting variability in some factors according to respondent agency affiliation and profession. Specifically, support for interprofessional communication and evaluative activities were viewed as insufficient. Impediments to these aspects of horizontal integration may be reflective of workload constraints, differences in agency operations or an absence of key structural features.

    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.

  15. Reliability Measure Model for Assistive Care Loop Framework Using Wireless Sensor Networks

    Directory of Open Access Journals (Sweden)

    Venki Balasubramanian

    2010-01-01

    Full Text Available Body area wireless sensor networks (BAWSNs are time-critical systems that rely on the collective data of a group of sensor nodes. Reliable data received at the sink is based on the collective data provided by all the source sensor nodes and not on individual data. Unlike conventional reliability, the definition of retransmission is inapplicable in a BAWSN and would only lead to an elapsed data arrival that is not acceptable for time-critical application. Time-driven applications require high data reliability to maintain detection and responses. Hence, the transmission reliability for the BAWSN should be based on the critical time. In this paper, we develop a theoretical model to measure a BAWSN's transmission reliability, based on the critical time. The proposed model is evaluated through simulation and then compared with the experimental results conducted in our existing Active Care Loop Framework (ACLF. We further show the effect of the sink buffer in transmission reliability after a detailed study of various other co-existing parameters.

    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.

    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

    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

    Full Text Available Abstract Background S. Chiara hospital is the only neonatal intensive care unit (NICU in the Province of Trento (Italy. It serves a population of about 460000 people with about 5000 infants per year, admitting the totality of the inborn and outborn VLBWI of the province. The aim of this work is to compare mortality, morbidity and neonatal treatment of the very low birth weight infants (VLBWI of Trento area with those recorded in the Vermont Oxford Network (VON during 2004. Methods In this retrospective analysis, the rates of complications and related treatments reported in VLBWI admitted in the S. Chiara NICU during the period 2000–2005 were compared with those recorded in the VON in 2004. The analysis included both the total populations and different weight groups. Results The frequency of inborn infants was significantly higher in Trento than in VON: 91% vs 84% (MH 8.56; p-value 0.003. The administration of prenatal steroids (82% vs 74%; MH 7.47 and p-value 0.006 and caesarean section were significantly more frequent in the Trento area than in VON. In Trento significantly more VLBWI with BW ≤ 1000 grams were given surfactant prophylaxis compared with VON and significantly fewer VLBWI in every Trento weight group developed RDS (MH 18.55; p-value 0.00001. Overall rates of complications (CLD, PDA, NEC, IVH were significantly lower than in the Vermont Oxford Network. In CLD and PDA the differences were marked also in infants weighting less than 1000 grams. Overall rates of PNX, PVL, severe grade of ROP and mortality were similar in the two populations. In Trento, significantly more infants were discharged on human milk than in VON, in both the overall population and in BW sub-groups. Conclusion On the basis of this analysis, a less aggressive therapeutic strategy based on perinatal prevention in global management, such as that employed in Trento area, may be associated with an improvement in clinical outcomes in very low birth weight infants.

    2015-09-01

    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.

  20. Mode of effective connectivity within a putative neural network differentiates moral cognitions related to care and justice ethics.

    Directory of Open Access Journals (Sweden)

    Ricardo Cáceda

    Full Text Available BACKGROUND: Moral sensitivity refers to the interpretive awareness of moral conflict and can be justice or care oriented. Justice ethics is associated primarily with human rights and the application of moral rules, whereas care ethics is related to human needs and a situational approach involving social emotions. Among the core brain regions involved in moral issue processing are: medial prefrontal cortex, anterior (ACC and posterior (PCC cingulate cortex, posterior superior temporal sulcus (pSTS, insula and amygdala. This study sought to inform the long standing debate of whether care and justice moral ethics represent one or two different forms of cognition. METHODOLOGY/PRINCIPAL FINDINGS: Model-free and model-based connectivity analysis were used to identify functional neural networks underlying care and justice ethics for a moral sensitivity task. In addition to modest differences in patterns of associated neural activity, distinct modes of functional and effective connectivity were observed for moral sensitivity for care and justice issues that were modulated by individual variation in moral ability. CONCLUSIONS/SIGNIFICANCE: These results support a neurobiological differentiation between care and justice ethics and suggest that human moral behavior reflects the outcome of integrating opposing rule-based, self-other perspectives, and emotional responses.

    2016-06-01

    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 < .0001; Kruskal-Wallis χ(2) = 149.9 and 56.5, p < .0001, respectively). In multivariable models, it predicted high EE (but neither low EE nor low/high DP). EE/DP single items were correlated with parent subscales (Spearman's ρ = .89 and .81, p < .0001; Kruskal-Wallis χ(2) = 230.98 and 197.84, p < .0001, respectively). In multivariable models, the EE item predicted high/low EE, whereas the DP item predicted only low DP. Therefore, the three single-item measures tested varied in effectiveness as screeners for EE/DP dimensions of burnout. PMID:25716107

    This is an integrative literature review that analyzed the scientific knowledge produced on the orientation of Brazilian basic care services to primary health care focusing on child health. Searches were carried out in SciELO, Lilacs and Medline databases using descriptors "primary health care", "family health program", "child health" and "evaluation of health services". Studies published in Portuguese, English and Spanish between 2000 and 2013 were selected. A total of 32 studies were chosen and characterized in relation to the features of primary health care, region of the country, type of study and authors' practice area. A thematic review of studies was conducted and resulted in two categories: child care in the context of Brazilian primary health care and primary health care features: limitations to child care. It can be understood that Brazilian primary health care services are heterogeneous regarding the presence and scope of essential child care characteristics. There is a lack of structural and process changes in the services to substantially plan child care actions in basic care.

    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.

    2014-08-01

    Urban contexts introduce unique challenges that must be addressed to ensure that areas of high population density can function when disasters occur. The ability to generate useful data to guide decision-making is critical in this context. Widespread adoption of electronic health record (EHR) systems in recent years has created electronic data sources and networks that may play an important role in public health surveillance efforts, including in post-disaster situations. The Primary Care Information Project (PCIP) at the New York City Department of Health and Mental Hygiene has partnered with local clinicians to establish an electronic data system, and this network provides infrastructure to support primary care surveillance activities in New York City. After Hurricane Sandy, PCIP generated several sets of data to contribute to the city's efforts to assess the impact of the storm, including daily connectivity data to establish practice operations, data to examine patterns of primary care utilization in severely affected and less affected areas, and data on the frequency of respiratory infection diagnosis in the primary care setting. Daily patient visit data from three heavily affected neighborhoods showed the health department where primary care capacity was most affected in the weeks following Sandy. Overall transmission data showed that practices in less affected areas were quicker to return to normal reporting patterns, while those in more affected areas did not resume normal data transmissions for a few months. Rates of bronchitis increased after Sandy compared to the two prior years; while this was most likely attributable to a more severe flu season, it demonstrates the capacity of primary care networks to pick up on these types of post-emergency trends. Hurricane Sandy was the first disaster situation where PCIP was asked to assess public health impact, generating information that could contribute to aid and recovery efforts. This experience allowed us to

    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

    Obesity prevention in children offers a unique window of opportunity to establish healthful eating and physical activity behaviors to maintain a healthful body weight and avoid the adverse proximal and distal long-term health consequences of obesity. Given that obesity is the result of a complex interaction between biological, behavioral, family-based, and community environmental factors, intervention at multiple levels and across multiple settings is critical for both short- and long-term effectiveness. The Minnesota NET-Works (Now Everybody Together for Amazing and Healthful Kids) study is one of four obesity prevention and/or treatment trials that are part of the Childhood Obesity Prevention and Treatment (COPTR) Consortium. The goal of the NET-Works study is to evaluate an intervention that integrates home, community, primary care and neighborhood strategies to promote healthful eating, activity patterns, and body weight among low income, racially/ethnically diverse preschool-age children. Critical to the success of this intervention is the creation of linkages among the settings to support parents in making home environment and parenting behavior changes to foster healthful child growth. Five hundred racially/ethnically diverse, two-four year old children and their parent or primary caregiver will be randomized to the multi-component intervention or to a usual care comparison group for a three-year period. This paper describes the study design, measurement and intervention protocols, and statistical analysis plan for the NET-Works trial.

  2. 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 Call Quality is prevalent and widely used by carriers that transport the calls of telecom operators. Butfrom end-users perspective call quality has been not taken very seriously until now and this is the reasonfor surge in GSM gateways which resulted in interconnect revenue loss and more importantly the callquality. This particular research developed as QMeter® is focussed to address and derive the callquality parameters from end-users perspective. The call parameters used in our research are SignalStrength, the successful call rate, normal drop call rate, handover drop rate. An attempt to visualizethose parameters for better understanding of where the quality is bad with respect to various parametersproposed and implemented. To address the issues of quality in subscriber segment and satisfy its demandfor quality of services, an alternative solution proposing the varying tariff based on call and bandwidthquality parameter is proposed. Call statistics for the bundles of ten calls and ten data sessions isproposed to better address the tariff redemption procedures. The proposed methods of qualitymeasurement has been compared and correlated with subjective scores for hundreds of calls and theresults show that our results are 85% on an average in correlation with subjective scores.

We evaluated current documentation of BMI, and documentation and control of associated risk factors by BMI category, based on electronic health records from a 12-clinic primary care network. Methods We conducted a cross-sectional analysis of 79,947 active network patients greater than 18 years of age seen between 7/05 - 12/06. We defined BMI category as normal weight (NW, 18-24.9 kg/m2, overweight (OW, 25-29.9, and obese (OB, ≥ 30. We measured documentation (yes/no and control (above/below of the following three risk factors: blood pressure (BP ≤130/≤85 mmHg, low-density lipoprotein (LDL ≤130 mg/dL (3.367 mmol/L, and fasting glucose Results BMI was documented in 48,376 patients (61%, range 34-94%, distributed as 30% OB, 34% OW, and 36% NW. Documentation of all three risk factors was higher in obesity (OB = 58%, OW = 54%, NW = 41%, p for trend Conclusions In a large primary care network BMI documentation has been incomplete and for patients with BMI measured, risk factor control has been poorer in obese patients compared with NW, even in those with obesity and CVD or diabetes. Better knowledge of BMI could provide an opportunity for improved quality in obesity care.

    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.

    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.

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

    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.

    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.

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.

    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.

    Chronic wounds have been steadily increasing in the developed countries, caused by the combination of aging population and obesity. In the EU-27 area there are around 4 million patients yearly requiring hospital care for wounds. The total costs of treatment for a wound are around €6650-€10000 per patient. The medical supplies and equipment market, where wound care products belong to, is estimated to grow 5.8% between 2013 and 2018. These growth and value creation opportunities have been notic...

    Full Text Available BACKGROUND: Dementia is one of the most disabling and burdensome diseases. Incontinence in people with dementia is distressing, adds to carer burden, and influences decisions to relocate people to care homes. Successful and safe management of incontinence in people with dementia presents additional challenges. The aim of this study was to investigate the rates of first diagnosis in primary care of urinary and faecal incontinence among people aged 60-89 with dementia, and the use of medication or indwelling catheters for urinary incontinence. METHODS AND FINDINGS: We extracted data on 54,816 people aged 60-89 with dementia and an age-gender stratified sample of 205,795 people without dementia from 2001 to 2010 from The Health Improvement Network (THIN, a United Kingdom primary care database. THIN includes data on patients and primary care consultations but does not identify care home residents. Rate ratios were adjusted for age, sex, and co-morbidity using multilevel Poisson regression. The rates of first diagnosis per 1,000 person-years at risk (95% confidence interval for urinary incontinence in the dementia cohort, among men and women, respectively, were 42.3 (40.9-43.8 and 33.5 (32.6-34.5. In the non-dementia cohort, the rates were 19.8 (19.4-20.3 and 18.6 (18.2-18.9. The rates of first diagnosis for faecal incontinence in the dementia cohort were 11.1 (10.4-11.9 and 10.1 (9.6-10.6. In the non-dementia cohort, the rates were 3.1 (2.9-3.3 and 3.6 (3.5-3.8. The adjusted rate ratio for first diagnosis of urinary incontinence was 3.2 (2.7-3.7 in men and 2.7 (2.3-3.2 in women, and for faecal incontinence was 6.0 (5.1-7.0 in men and 4.5 (3.8-5.2 in women. The adjusted rate ratio for pharmacological treatment of urinary incontinence was 2.2 (1.4-3.7 for both genders, and for indwelling urinary catheters was 1.6 (1.3-1.9 in men and 2.3 (1.9-2.8 in women. CONCLUSIONS: Compared with those without a dementia diagnosis, those with a dementia diagnosis
